PACKAGING RELATED SYSTEM and APPARATUS

TECHNICAL FIELD [0002] The present invention generally relates to the field of packaging, and in particular of any or all systems and devices for assisting the packaging of a product and / or for combined packaging and packaging of a product, yet more specifically but not exclusively, systems and devices for at least embedding a measured portion of settling product before packing / bagging to achieve a reduction in the volume of the measured portion of settling product

BACKGROUND OF THE INVENTION [0003] Packaging processes, e.g. bagging, settling products, are well known and numerous. One illustrative non-limiting class of commonly bagged, settling products consists of foodstuffs, in particular food snacks.

[0004] Probably the most well-known element of the food snacks family are foodstuffs characterized as "chips", e.g. potato, corn, tortilla, etc., salty, spicy, or other. From the documented sale of packaged snacks at $ 68 billion in 2008 (reportlinker.com), Rockville, Maryland (USA) packaging facts predict sales at around $ 82 billion by 2013, total market growth of around 20%. Everything indicates that despite the recent / current economic downturn and its impact on household budgets and the like, consumers are eating more snacks than ever before. While the various probable reasons generally anticipate increased and growing sales of such foodstuffs, this does not change the fact that

[0005] In addition to the introduction of new food snacks (e.g. 350+ new salty snacks launched in the United States in 2009 according to the Global Database of New Products operated by Mintel (NY, USA)), one of several thematic areas considered the packaging of the product considered beneficial in anticipation of an increase in revenues and profit. For example, among other things, the sale of a fixed quantity, i.e. weight in otherwise smaller bags, bags, etc. (i.e., bags of smaller volume) reduces the cost of packaging material by reducing material / resource consumption, and thus contributes positively to the bill profit and loss.

[0006] As outlined herein, FIG. 1, the processes for making sacks and packaging are generally characterized by a metering station 20, a bag manufacturing and packaging station 22, and a station 24 for transporting or transporting sacks. Such prior art bag and packaging systems are depicted in FIGS. 2 and 3 (US Patent No. 7,328,544 (Yokota et al., FIGS. 1 and 2) with a less "busy" representation of the bag and bag making station shown in FIG. 4 (U.S. Patent No. 5,732,532 (Fujisaki et al.), FIG.

1).

[0007] In general, a measured portion (i.e., the selected mass of product to be packaged) leaves the metering station (FIGURES 2 and 3) or the hopper (FIG. 4). The measured portion is directed to the chute or chute (e.g., the shank of the forming device (Fig. 3)) to pass through it. The film fed from the roll is directed to and onto the mandrel and finally around it and is then longitudinally sealed to form the foil sleeve (FIG. 4). Then, the sleeve formed in this way is sealed transversely by means of a welding machine lying under the pipe, in order to receive and maintain a measured portion of the product,

It goes without saying that many real challenges have obviously been confronted and at least somewhat overcome in the development of the processes, systems and devices of FIG. 1-4 and the like. While Yokota and others seem to focus on the adhering bags coming from the bagging and packaging station (1: 49-67), and Fujisaki and others blocking the filling passages of the cylindrical mandrel (2: 7-35), little if any something done in connection with the preparation of the product prior to packaging in addition to the establishment of metered product administration, to improve bagging and packaging operations of the product and the quality and / or nature of the packaged product. Thus, in the light of the above, it is considered that the related production of bags and the packaging of the product remain a challenge and it is considered that real and perceivable benefits are achievable. In order to, among other things, reduce packaging materials, deliver a measured portion of improved nature and / or quality and produce bagged food snacks or the like having a true and / or perceived improved nature (e.g., increased mass-volume ratio for the packaged product, reducing the amount of particles product or the like accompanying the packaged product, etc.), it remains advantageous and desirable to provide new and / or improved pre-packaging preparation steps and accompanying device / systems, thus improving the packaging process, system and device for the settling product.

SUMMARY OF THE INVENTION [0009] A device is provided to facilitate packaging of a settling product as well as a system comprising it. The device includes a rotary turret assembly, a turret-head base and an executive unit of the turret assembly associated operationally with the turret assembly to selectively actuate the turret assembly relative to the base of the turret assembly. The actuated turret assembly is characterized by containers for the deposition of the product. Each container for depositing the product from the product deposition containers may be positioned by actuating the actuated turret assembly to receive a metered portion of the settling product.

The actuated turret assembly or its product mounting containers preferably has, but not necessarily, a modular, easily replaceable or, in the case of containers, exchangeable or physically changed by adapting to more efficiently handle the processing of various settling products or to pack the target settling product. The turret is generally actuated, e.g. via, from among the various alternatives, an indexed rotation so as to thicken or embed a settling product held by the container from a plurality of product deposit containers.

The commissioning is preferably, but not necessarily, obtained by a selectively controlled mechanical system, in particular via a servo drive.

[0011] Containers among the product deposition containers may be properly characterized as pipes or sleeves having "open" opposite ends. Generally, the containers include the inlet part of the metered portion and the outlet part of the deposited metered portion, with the entrance part characterized by the cross-sectional area exceeding the cross-sectional area of ​​the outlet part. In the context of rotary compaction, the containers are "fed" by bursts arranged perimetrically in the turret assembly or turret body and can be adjusted in half to minimize the "embankment" of the product. The particular suitability container is configured to include an inlet portion characterized by a free funnel end that limits the metered-dose container,

[0012] The base of the turret assembly is generally adapted to allow for selectively passing the deposited measured portion of a settling product from a selected container, e.g. at a point of emptying the container. More specifically, the passage of an embedded measured portion of a settling product from a container positioned at a draining point is achieved by selectively activating the port of depositing a metered portion, e.g. a valve assembly, over which filled product containers can be set to discharge a metered set portion of the settling product from the device to a packaging station, preferably to a mandrel forming a bag having at least a segment including openings for passage of air.

[0013] Functionally, the trigger turret is moved, by means of selective actuation, relative to the base of the turret and located above the measuring station. More specifically, the indexed rotation start occurs in relation to the position / exact filling location defined by the metering station and the position / exact place for emptying the turret defined by the base, i.e. its discharge port. Preferably, the metered product will be collected at the loading station and released at the discharge station at approximately the same time.

[0014] As the container "x" of the total number "N" of the containers of the actuated turret assembly is set to empty at the emptying station, the container "x + 1" is preferably arranged for pre-filling in the filling station near the drain station, while when the "x + 2" container has passed the initial deposition / compaction repeat, and the "x-1" container goes into the "on board" setting for emptying (i.e., it is next in the queue for emptying). Indexing occurs whenever an embedded and formed measured portion of product is discharged from the turret assembly into a funnel / forming apparatus for bag production, preferably a vent of a ventilated tube, with several portions of the measured product introduced into the turret assembly during the actuation cycle. By such an operation, an embedded and formed portion of the measured mass of the settling product, i.e. the weight of the product with reduced volume, is ready for packaging. The more specific features and advantages obtained due to these features will become apparent with reference to the figures of the drawings and the DETAILED DESCRIPTION OF THE INVENTION.

DETAILED DESCRIPTION OF THE INVENTION [0016] In general, the invention relates to a device for compacting a product blank and to increase the density of a product in a package. The density refers to the density of the product in the package. The object is to form and concentrate the intermediate intermediate product, which is subsequently discharged into the packaging device and finally into the packaging. An additional object in one embodiment is to ensure that increased compaction is maintained throughout the packaging operation. Applicants have found that the formation and compaction of the intermediate blank, and then the discharge of said blank for packaging purposes results in an increased compaction of the product. The product blank refers to the product portion received.

[0017] Due to the resulting increased product compaction on the bag making machine, smaller deposition occurs in turn during the subsequent dispatch, handling and packaging exposition. Thus, the apparatus and method of the present invention ensure that the packaging displayed on the shelf will more closely resemble the packaging seen on the bag making machine. The term "bag making machine" as used herein refers to any packaging device. The device can be used in a wide range of bag making machines including, but not limited to, a vertical forming, filling and sealing machine, and a horizontal molding, filling and sealing machine, a "bag-in-box" device as well as a machine for cardboard packaging. Similarly, a packaging device also called a filling, sealing machine for producing bags, whereby the pre-formed bags are opened, filled and welded, and can also be used. The finished packages described herein may include traditional flexible packaging associated with snack products, vertical packaging, carton packaging, "bag-in-box" packaging, and other products containing a product that is subject to settling.

[0018] The device can be used to increase the concentration of various products including food products such as chips, pretzels, biscuits, pasta, nuts, cereals and seeds. Similarly, the present invention is also applicable to individually wrapped products such as individually wrapped peppermint candies or other candies that are susceptible to subsidence. The device and the method also work with other dry products including dog food, cat food, etc.

[0019] The description then goes directly to the general reference to FIG.5 and FIG.6-11 in FIG.5-21. The steps of processing the improved bag making and packaging process are generally shown in FIG. 5, namely adding a product deposition station, and more specifically, a deposition station for the measured product andforming a portion of the measured product into the process of FIG. 1. Preferred, non-limiting devices for facilitating the packaging (i.e., improved packaging) of settling solids are generally shown in FIG. 6 and in several views in FIG. 7-11. Similarly, details about its subassemblies, namely the valve assembly, are also provided, as preferred, but not necessarily, shown in the views of FIGs. 12 and 13 and turret pockets, as preferred, but not necessarily, illustrated in FIG.14 and

15. Finally, contemplated devices equipped with alternative turret assemblies of FIG. 14 and 15 are also shown in combination with the improved bag forming tube / stylus in FIGS. 16 and 17, as well as the main processing elements of FIG. 6 also shown in FIG. 18. Before going on to a detailed description, it is worth mentioning a few preliminary matters.

[0020] First, while the subject of the packaging / packaging improvement is derived from foodstuffs, more specifically food snacks, and more specifically those characterized properly as "chips", the subsequently presented process, the system and the device need not be limited to such a "product" ". In the case of a settling solid or semi-solid product, foodstuffs or other substances to be measured and subsequently packaged, in particular bagging, among others consideration of a favorable volume reduction by deposition or compaction before packaging is considered. Theoretically, a portion of the product (i.e. a predetermined weight (i.e., weight) of the packaged product) is to be reduced in volume without departing from the quality or nature of the product (e.g. in the case of chips or the like, perceptible breakage thereof).

[0021] Secondly, while the description below takes place with reference to previously known processes and systems, it need not be so limited. Commercially it is considered advantageous and / or desirable and reasonable for a machine for existing current "in-plant" operations to provide a position for embedding or embedding / forming a product portion within the frame or operating range of an existing bag and packaging station. A modernized deposition system (i.e., a modular or turnkey station, which in turn may be adapted to be modular) is designed to fit above or in an existing sack manufacturing frame in the area above the funnel / product forming device with minimal modifications to the manufacturing machine bags. In addition, it is considered advantageous that the position itself is susceptible to adaptation,

[0022] Third, in connection with the desire to produce many different "sizes" of the product, and again, as noted above, the processing of different products or product styles, the loss of the product is to be minimized (i.e., the whole portion of the product is to be packaged or bagged) . For example, and without limitation, the processing of chips for the production of bags intended for one person represents a greater potential loss than the processing of chips for the production of "family" bags. While it has been shown that it is advantageous to form an embedded measured portion of the product, it is particularly advantageous to produce and preserve an embedded metered portion, i.e. to produce a deposited and formed measured portion that is packaged or bagged. Even more precisely, using the following processing steps, systems and devices, the cross-section of the deposited and formed metered portion mimics the cross-section of a bag forming machine or a bag forming mandrel. Thus, in the light of the above, a more coherent and accurate bagging operation is realized. the cross-section of the deposited and formed metered portion mimics the cross-section of a bag forming machine or a bag forming mandrel. Thus, in the light of the above, a more coherent and accurate bagging operation is realized.

[0023] Referring now to FIG.5, an improved bag and packaging process is illustrated, namely a process characterized by a deposition or deposition / forming step, and more specifically a step 21 of depositing or embedding / forming a measured portion of product. Instead of a metered portion of the product passing directly to the bag manufacturing and packaging station, e.g. introducing a metered product portion to pass through the bag forming apparatus (i.e., through the squeegee forming bag or tube clearance preferably includes a step (FIG.4)), this interfering process, namely compacting, deposition and / or forming an embedded pre-selected system of a measured portion of product. As will be described in detail in detail in conjunction with the presentation of system and device details, improved, the non-limiting bag and packaging process can be properly characterized by the step of mixing a metered product portion as one or more inertia changes communicated with the trigger turret assembly that maintains a metered product portion through at least one deposition or deposition / forming chamber. As should be noted, for products or products susceptible or susceptible to settling, e.g. chips, as opposed to, for example, unshelled nuts, a reduction in the volume of a given product mass (i.e., a measured portion of product) is achieved and results in, among others, a commensurate reduction packaging materials (e.g. bag forming). as by one or more inertia variations transmitted with respect to the actuated turret assembly being operated, which keeps the metered portion of the product through at least one deposition or deposition / forming chamber. As should be noted, for products or products susceptible or susceptible to settling, e.g. chips, as opposed to, for example, unshelled nuts, a reduction in the volume of a given product mass (i.e., a measured portion of product) is achieved and results in, among others, a commensurate reduction packaging materials (e.g. bag forming). as by one or more inertia variations transmitted with respect to the actuated turret assembly being operated, which keeps the metered portion of the product through at least one deposition or deposition / forming chamber. As should be noted, for products or products susceptible or susceptible to settling, e.g. chips, as opposed to, for example, unshelled nuts, a reduction in the volume of a given product mass (i.e., a measured portion of product) is achieved and results in, among others, a commensurate reduction packaging materials (e.g. bag forming).

[0024] FIG. 6 provides a perspective view of a filling device using one embodiment of the invention including a deposition chamber. In FIG. 6, the deposition device 30 is located between the metering station 20, characterized by the weight 23 and the receiving hopper 25, and the product feed cylinder 60 for the forming, filling and sealing machine. Weight 23 may comprise virtually any weight known in the art. In one embodiment, the weight 23 is a statistical weight. As shown, a weighing hopper 23 is provided with a receiving hopper 25. The receiving hopper 25, or a series of funnels, receives and guides the product into the bag making machine behind it. The receiving hopper 25 used here refers to any device behind the scales, but before the deposition device that receives and directs the product. The receiving hopper 25 may be attached to the scales 23 and be its element and may comprise vertical or oblique walls. In one embodiment, a metal detector is located between the scale 23 and the receiving hopper 25 for monitoring foreign bodies. Those skilled in the art will recognize that the receiving hopper 25 is not necessary in all embodiments. Behind the receiving hopper 25 and the scale 23 there is a deposition device 30.

[0025] As shown, the deployment device 30 comprises one deposition chamber, vibrator 31 and valve 72 of the valve assembly 38. The deposition device, as used herein, refers to a device that receives and takes up a quantity of product to form an intermediate pre-concentrate of the compacted product. The deposition chamber 40 is a separate chamber that receives and holds the product. In one embodiment, the deposition chamber 40 has four vertical walls and an open top and bottom.

[0026] Applicants have found that collecting the product discharged from the scales 23 and holding the product for a certain period of time in the deposition chamber facilitates the deposition of the product and increases the compaction of the product. Increasing the product deposition during packaging results in reduced deposition after production. The deposition chamber can be shaken or vibrated through a vibrator 31 to facilitate and accelerate the deposition of the product. The time and amount of external energy needed, such as the vibrations required to facilitate deposition, depend on many factors including, but not limited to, product geometry, size and geometry of the deposition chamber, the size of the blank and the level of desired compaction. Those skilled in the art will be able to determine the amount of time and energy required to achieve the desired level of compaction. Other movements such as vertical, horizontal, rotary, vibratory and combinations thereof may also be passed to the deposition chamber to facilitate the deposition of the product, resulting in increased compaction. The vibrator 31, which is optional, may comprise any device that vibrates the deposition chamber. The vibrator 31 may be located at various locations of the deposition device. which vibrates the deposition chamber. The vibrator 31 may be located at various locations of the deposition device. which vibrates the deposition chamber. The vibrator 31 may be located at various locations of the deposition device.

[0027] Applicants have found that the geometry of the deposition chamber affects the shape of the packaged blank as well as the shape of the finished package, especially when the finished package is a traditional flexible bag. In one embodiment, the cross-sectional shape of the deposition chamber 40 is substantially similar to the desired shape of the blank. For example, in one embodiment, the seating chamber 40 has a substantially oval cross-section to mimic a substantially oval cross-section of a conventional flexible bag. Other cross-sections may be used, which include, but are not limited to, a circular or square cross-section.

[0028] The height of the deposition chamber 40 can vary according to the desired size and shape of the intermediate blank, which ultimately dictates the size and shape of the finished product. In one embodiment, the size of the deposition chamber is about 0.5 to 2.5 times the height of the finished package, and in one embodiment the deposition chamber is about 1.25 times the height of the finished package. The size of the chamber depends on various factors including the size of the required seating. In one embodiment, the height of the deposition chamber 40 is selected to fit properly between the balance and the packaging device without lifting the weight.

[0029] In one embodiment, the bottom of the deposition chamber 40 has a larger opening than the top of the deposition chamber. For some products susceptible to hanging, having a larger outlet diameter minimizes suspension. It helps to maintain the desired, compact shape of the product and results in faster and more efficient drainage.

At the bottom of the deposition chamber, there is a valve 72. Valve 72 may include a plurality of types of valves including sliding and swing valves. In one embodiment, the gate 72 is a sliding gate that allows fast and efficient discharge of the product from the deposition chamber.

[0031] Behind the valve 72 is a product delivery cylinder 60. In some embodiments, there is an intermediate funnel 99 that directs the product discharged from the valve 72 into the product delivery cylinder 60. The intermediate hopper 99 may comprise one or more funnels that may contain straight or sloping walls. In addition, the intermediate hopper 99 may have different shapes. In one embodiment, the intermediate funnel 99 has a shape similar to the shape of the deposition chamber.

[0032] In some embodiments, in accordance with the processing step from the receiving hopper 25 of the product delivery cylinder 60, each subsequent transition point has a larger diameter than the passage point in front of it. Thus, in such an embodiment, the intermediate funnel 99 has a larger diameter than the deposition chamber 40, but smaller than the product delivery cylinder 60. Such arrangement minimizes suspension and other disturbances of the combined blank.

[0033] Thus, the method of compacting the product blank starts with weighing the amount of product on the scale. The product is then guided and picked up in the deposition device. When the product is in the embedding device, with

the product is compacted to form a semi-finished product. As discussed, this can be done by storing the product for a period of time or by shaking, rotating and / or vibrating the deposition device. After concentrating the product, the product is discharged into the product delivery cylinder. It should be noted that the product may be discharged directly into the product delivery cylinder or it may be discharged into an intermediate hopper or chute prior to reaching the product delivery cylinder. Then, the blank is transferred from the product delivery cylinder to the packaging. As discussed above, the deposition device is located behind the balance and in front of the product delivery cylinder. Further, the deposition device may comprise only one deposition chamber or the device may comprise more than one deposition chamber.

[0034] In one embodiment, the deposition device 30 comprises only one deposition chamber. However, in other embodiments, the embedding apparatus 30 comprises more than one deposition chamber. In one embodiment, the two or more chambers 40 operate in parallel, each of which drains its blank into a further product delivery cylinder 60. In other embodiments, at least two chambers 40 act in series, whereby the first chamber is below the second chamber and the product partially seated in the first chamber before being deposited for further deposition in the second chamber. In one embodiment, one or more deposition chambers are located on the rotating deposition device.

[0035] Referring now to FIG. 7-11, a device 30 is generally shown to facilitate packaging, i.e. improved packaging, settling product by rotating the portion. The device alone or in a selected combination with further components associated with the process can be properly characterized as a system or station for embedding the product or embedding / forming the product. Preferably, but not necessarily, as previously mentioned, the general device or assembly of FIG. 7-11 are configured, dimensioned and / or readily adapted, or can be adapted to be included or attached by upgrading to known bag and packaging systems, e.g., without limitation, those of Ishida Co., Ltd. (Japan).

[0036] Generally, the apparatus 30 includes a trigger turret assembly 32 (refer also to FIGs. 11 and 12), a turret tool base 34, a turret-tool body 36 operatively associated with a trigger turret assembly 32 for selectively actuating the actuated assembly 32 turret with respect to the base 34 of the turret. In addition, the valve subassembly 38 (reference also to FIGS. 9 and 10) is preferably provided, namely, selectively actuated valve assembly to allow exit of the deposited and formed metered product portion from the trigger turret assembly 32 via the turret-base 34 of the turret assembly.

The actuated turret assembly 32 generally includes containers or containers 40 for depositing the product, preferably end-open containers (i.e., sleeves or pipes) which will be specified below, and the assembly body 42, e.g. mounting plates or spacers, upper 44 and lower 46 as shown, to hold the product depot containers and so define the assembly. Each container 40 for depositing the product from the product deposition containers is selectively set by selectively activating the actuated trigger assembly 32 (e.g., by mechanical, hydraulic or pneumatic drive and preferably as represented by the servo drive 48) to receive a metered portion of settling product. By actuating, reversing or otherwise actuating the turret assembly 32, e.g.

[0038] Theoretically, with respect to containers for forming and depositing a metered product, a preselected state of equilibrium or pseudo-equilibrium for the entry of a product into or out of the turret assembly is advantageous but unnecessary. As will be further specified in connection with the discussion of a preferred sequence of operations, the container for discharging the contents at time t0 is then transferred by actuating the turret assembly so that it is under the discharge from the metering station and filled therein at time t1. The "filled" container (FB) preferably, but not necessarily directly adjoined (i.e., behind it) to the emptied container (EB), see e.g.

FIG.9 (i.e. the emptying and filling operations of the containers are preferably, but not necessarily, performed side by side). Since the next, preferably filled, container substantially holding the seated and formed metered portion is positioned relative to the base of the turret assembly for discharging the contents, the pre-filled container commensurately passes the base of the turret assembly and by varying the inertia, it can be properly characterized as transferred from the state or a pre-filled position to a pre-embedded, embedded and formed state or position.

[0039] The driven turret assembly 32 is generally supported and more particularly preferably rotatably supported relative to the base of the turret assembly or base plate 34. The servomotor 50 of the servo drive 48 is functionally associated, via the shaft 52, the hub 54 of the shaft and the shaft sleeve 56 as shown, to the assembly, namely the body 42 of the assembly, to selectively transmit its movement.

[0040] The base 34 of the turret assembly is generally adapted to allow selective passage of the processed measured portions of product from the containers 40 of the turret assembly 32. Accordingly, with particular reference to FIG.9, the base 34 of the turret includes an output port, e.g. a notch or aperture 58 as shown, which is (see e.g. FIG.16) or may be (FIG.9) functionally associated with a sack manufacturing device / mandrel 60 and a slit peripheral edge 61 (i.e., gap 62) that allows and / or adjusts the reversible translational movement or reciprocal movement of the valve sub-assembly 38 of FIG. 12. Further non-limiting advantageous features of the turret base 34 of the turret assembly include, but need not be limited to, the use of an elongated through hole, e.g., a gap 64, extending adjacent and parallel to the output port 58, the cavity of the upper surface, and more specifically the channel cavity 66 as shown and additionally the guide or segment 68 of the overhanging guide or otherwise extending from the bottom surface 70 of the turret base 34 so as to abut and be parallel to the gap 62 is a slot-like peripheral edge 61. It should be noted with reference to FIG. 8 and 9, that the inner turret slot 64 of the turret-tool base is located downstream of the output port 58 and is generally dimensioned and configured to selectively pick up and feed particles, chips, etc., of the product. and more specifically, a channel cavity 66 as shown and additionally of a guide or segment 68 of a hanging guide or otherwise extending from the bottom surface 70 of the base 34 of the turret so as to abut and be parallel to the slot 62 of the slit peripheral edge 61. It should be noted with reference to FIG. 8 and 9, that the inner turret slot 64 of the turret-tool base is located downstream of the output port 58 and is generally dimensioned and configured to selectively pick up and feed particles, chips, etc., of the product. and more specifically, a channel cavity 66 as shown and additionally of a guide or segment 68 of a hanging guide or otherwise extending from the bottom surface 70 of the base 34 of the turret so as to abut and be parallel to the slot 62 of the slit peripheral edge 61. It should be noted with reference to FIG. 8 and 9, that the inner turret slot 64 of the turret-tool base is located downstream of the output port 58 and is generally dimensioned and configured to selectively pick up and feed particles, chips, etc., of the product.

[0041] Referring to FIG. 10, the rotating deposition device 30 is shown comprising eight depression chambers 40a-h located above the stationary retoucher table 34, a gate 72 and a vibrator 31. While the figure illustrates eight deposition chambers 40a-h. , other numbers of deposition chambers can also be used. Those skilled in the art understand that the number of deposition chambers required depends on many factors, including, but not limited to, product geometry, desired size and weight of each intermediate and desired bagging capacity per minute, required deposition time, etc.

[0042] In the rotating deposition device 30, the deposition chambers 40a-h may be arranged at different locations. In one embodiment, the centers of each of the deposition chambers are evenly spaced along the turret table 34. In one embodiment, the chambers are evenly spaced and oriented like the spokes of the wagon wheel. As shown, the deposition chambers are inclined with respect to the turret table 34 to maximize the number of chambers that fit on the turret table 34.

[0043] In the illustrated embodiment, the deposition chambers 40 have an open top and a bottom, i.e. the product is maintained in the deposition chamber 40 by the presence of the stationary turret table 34. In such an embodiment, the deposition chambers are slid and rotate on the turret table 34. A hole 92 is provided in the table 34 of the turret over the gate 72. In one embodiment, the shape of the opening corresponds to the shape of the deposition chamber. The chamber located in the position above the gate 72 and aligned with the hole 92 is called the outlet chamber 40a. The product in the discharge chamber 40a is held by the gate 72. Accordingly, when the gate 72 is opened, by sliding or otherwise, the product falls through the opening 92 in the turret table 34 and passes through the open gate 72.

[0044] In one embodiment, behind the gate 72 and below it is a product delivery cylinder 60. In such an embodiment, the compacted blank is discharged from the discharge chamber into the product delivery cylinder 60, where it is in turn packaged in a bag making machine.

[0045] The deposition chambers 40 can be filled at various locations. In one embodiment, the discharge chamber 40a is also the same deposition chamber that receives the product, called the receiving chamber. In this embodiment, after draining the product from the discharge chamber 40a, the valve 72 will close. Then, the outlet chamber 40a receives the product. All deposition chambers, in turn, will move one space at a time when the product settles in the deposition chamber and becomes more concentrated. Thus, in some embodiments, the reception and discharge do not take place simultaneously.

[0046] FIG. 10 and 11, however, show an embodiment in which reception and discharge do not take place in the same chamber. As shown in FIG. 10, the discharge chamber 40a discharges the product and another chamber, the receiving chamber 40c receives the product from the receiving hopper 25. In one embodiment, the discharge and collection takes place simultaneously. Thus, the discharge chamber 40a after the discharge of its product rotates by two positions to become the receiving chamber 40c, at which time it receives the product. In other embodiments, the discharge chamber 40a rotates only one position before it becomes the receiving chamber, while in other embodiments the discharge chamber rotates a plurality of positions before it becomes the receiving chamber.

[0047] Receiving chamber 40c, after receiving its product, rotates clockwise through the positions until it becomes the outlet chamber 40a again. Although the example has been described for rotation in a clockwise direction, this should not be a limitation, since the device can also rotate counter-clockwise.

[0048] During the rotation of the deposition chambers, the product becomes more compacted. In one embodiment, the vibrator 31 vibrates the product in the deposition chambers to facilitate the deposition of the product. The vibrator 31 can be located in various places, among others, but not limited to a fixed turret table 44 attached to the chambers 40 or otherwise attached to a rotating deposition device or other support structure.

[0049] As shown in FIGs. 10 and 11, the receiving hopper 25 is located on top of the rotating deposition device 30. The receiving hopper 25 directs the product to the receiving chamber. As indicated above, the receiver hopper 25 may be directly below the weight of 23 or may be below another funnel or a series of funnels.

[0050] FIG. 11 is a perspective view of a rotating deposition device comprising a plurality of deposition chambers at half rotation, the aperture 92 provided on the stationary table 44 is also visible. As shown, the chambers are in the middle of rotation so that the chambers do not receive or discharge the product. However, in other embodiments, the product is received and / or discharged during rotation. In some embodiments, however, it is desirable that the compacted blank is preserved in its compact state after the blank has been formed.

[0051] In Fig. 11, a fixed top 35 is shown. Top 35 acts to ensure that the product in the deposition chambers does not escape from the deposition chambers. In addition, the top 35 acts to stop the external components from entering the embedment device and subsequently before packaging. Top 35 is not necessary in all embodiments and those skilled in the art will know which processing conditions will justify such a top.

[0052] As shown, the intermediate funnel 99 and the recipient cylinder 60 of the product are shown behind the opening 92. In FIG. 11. the recipient cylinder 60 of the product is part of the bag forming apparatus in a vertical forming, filling and sealing machine. In one embodiment, the product receiving cylinder 60 is directly connected to the rotating device 30. In other embodiments, the recipient cylinder 60 of the product is not directly attached to the rotating device 30. The product receiving cylinder 60 can be separated from the rotating device 30 by a gap or can be connected via other equipment such as the middle funnel 99.

[0053] In one embodiment, the product in the package contains a product from only one deposition chamber. In such an embodiment, the amount of product received in the receiving chamber is equal to the amount of product in the finished package. In yet other embodiments, the finished package includes two product blanks. In one embodiment, the package includes a product from at least two different deposition chambers. In other embodiments, the package includes two product blanks from the same chamber. In such an embodiment, the first preform is first formed and discharged and then a second blank is formed in the same chamber and subsequently discharged.

[0054] Applicants have found that the density of some products is further increased when two or more smaller semi-finished products are compacted separately and then added to one package. For example, when a finished product is to contain two product blanks, blanks formed from two different compartments will be assembled in a single package. With reference to FIG. 10, in such an embodiment, one package will include a product discharged from the withdrawal chamber 40a as well as a product from the chamber 40h located one behind the discharge chamber 40a. Thus, the product from both chambers 40a / 40h is deposited in a vertical forming, filling and sealing machine for packaging in a single package.

[0055] In one embodiment, the height of each chamber is selected so that the existing device can be upgraded by using portions of the portion, without, for example, lifting the weight. As an example, in one embodiment due to the method with multiple portions, the deposition chambers can be made of a smaller height due to the height distributed over a plurality of chambers and as a result the weight does not have to be moved. This results in a reduction of the capital costs of upgrading an existing device.

[0056] Applicants have found that after inducing settlement, the preform retains its shape and compaction when it is producing bags. embedding while packed. This results in a smaller embedment after packaging giving the client a fuller package that more closely resembles a fuller bag appearance on the machine. As discussed previously, increased packaging reduces deposition after packaging, resulting in several advantages. One such benefit is the possibility of using a comparatively smaller package for the same product weight. This results in a reduction in production costs because less material is needed to make the package. In addition, this results in a reduction in shipping costs as more packages can be accommodated in a given volume. Also, this allows you to put more packages on the store shelf, because smaller packages take up less space. Likewise, smaller packages allow the consumer to store the same amount of products in a smaller space, thereby freeing up valuable space in the pantry.

[0057] As established, the device and method ensure that the same amount of product can be packaged in a comparatively smaller package. The smaller package may have reduced height, width or combinations thereof compared to the previous packaging. In one embodiment, the width of the package is not changed, but only the height dimension is changed. Such an embodiment minimizes the modifications required for the bag making machine. The following examples show the efficacy of one embodiment of the present invention and are provided for purposes of illustration only. Accordingly, the following examples should not be considered as limiting.

Control [0058] The test was carried out using chips with a mass of 21.5 ounces. Wheat flakes were thin wafers with ridges. The embedding device was not used during the inspection. The bags had a width of 12 inches, a total height of 18.75 inches and a usable height of 17.75 inches after subtracting 1 inch on top and bottom seals. The empty space in each bag was measured and the full level of each bag was calculated. The empty space was measured by measuring the average level of the product in the package. The packaging removed from the bag making machine, which was a vertical forming, filling and sealing machine, was on average about 86% full and had an average product level of 15.25 inches. Then, to determine the condition of packages after being on the shelf, the packaging was subjected to a simulated retail process, which included simulated transport, transfer and shelf life of a typical package. After the simulation, the empty space was measured and the filling of each bag was calculated on average to approximately 78% with a product level of 13.85 inches. Thus, the filling of the packaging decreased by an average of about 8% after the shelf simulation and the product level decreased by an average of 31.4 inches.

One serving [0059] During the next test, a non-rotating deposition device containing one deposition chamber similar to that of FIG. 2 during the operation was used using the one-portion method, so that each package contained one pre-product blank. The deposition device had deposition chambers having a substantially oval cross-section and a width of 12 inches. Due to the embedding of the product, a smaller package was used. The smaller package had a width of 12 inches and a height of 16.75 inches with a usable space of about 15.75 inches. The packaging machine was about 86% full on the packaging machine and had a product level of about 13.55 inches. Thus, the deposition device reduced the same amount of product in a bag of the same width from the product level of 15.25 inches to the level of product 13, 55 inches on a bag making machine. After the simulation, the packaging shelves were approximately 82% full and had a product level of about 12.85 inches. Thus, filling the package decreased only by 4% and resulted in a fuller bag compared to the control. In addition, the product level decreased by only 0.7 inches, which is about half of the decrease experienced during the inspection.

Multiple portions [0060] In the next study, the same apparatus was used using the method in multiple portions, the finished package containing two product blanks. Thus, in this embodiment, the deposition chamber formed and removed the blank, and then the same deposition chamber subsequently formed and discharged the second preform into the same package as the first disposed preform. A sack of the same size as for one portion was used for testing with numerous portions. On the bag making machine, the packages were approximately 87% full and had product levels of about 13.65 inches. After the simulation, the packaging shelves were approximately 83% full and had a product level of about 13.15 inches. So, compared to the one-serving method,

[0061] Both a single portion and a double portion produced a smaller package that contained the same amount of product as the larger bag during the inspection but to produce less material. Accordingly, the product's density resulted in reduced production costs, reduced transport costs, an increased number of packages available for a given size of retail space, packaging that took up less space in the pantry and packaging that seemed fuller for the retail consumer.

[0062] In a re-reference in general to FIG. 7-11 and in particular with reference to FIG. 12 and 13, a preferred, non-limiting, valve subassembly is shown, and more specifically a selectively actuated valve subassembly 38. The selectively actuated valve sub-assembly 38 generally includes a valve 72 and a valve base 74 operatively supporting the valve 72. The valve base 74, in turn, but not necessarily, includes an upper valve guide or tray 76 joined together with a tumbler 72 for reversible retraction in the path 66 the tumbler (FIG. 9), and the lower valve guide 72, namely the track guide 78 for moving along a path or segment 68 of the path to support the operatively upper valve guide 76 of the valve 72. Although a non-limiting "shifting" of the valve is indicated,

[0063] As shown, the selectively actuated valve subassembly 38 is preferably activated by an additional servo drive 48; namely a servomotor 50 'and a connecting arm 80 which converts the rotary motion into a translational or reciprocating motion to provide, among other things, fast and reliable reversal motion of the valve. The connecting arm 80 generally includes a rotary element or segment 82 integral with the servo drive shaft 53 to extend therefrom and a coupler 84, the first end portion of which is attached to the free end of the rotating section and whose second end portion is anchored in the part the lower guide 78 of the valve. As can be easily seen by reference e.g. to FIG. 7, one or more of the components or support unit 86 as depicted maintains the 48 'servo drive.

[0064] Operationally, and with reference to FIG.9, when the free end of the rotating segment 82 is pulled away from the base 34 of the turret assembly, the rotation of the servo shaft 53 in the clockwise direction as indicated in the figure, the coupler 84 also it reacts so as to result in a pulling movement (i.e., an opening or "opening" of the valve) or an action that is transmitted to the valve subassembly 38. In contrast to the previous situation, after the product has been released / released, the free end of the rotary segment 82 is pulled towards the base 84 of the turret assembly, rotation of the servo shaft 53 counterclockwise in the figure, the connector 84 also reacts so as to cause as a result, the pushing motion (i.e., "closing" of the valve) or action, which is passed to the valve subassembly. It should be noted that the extremely fast valve actuation is advantageous because it prevents disturbances of the deposited and formed measured portion of the product and allows the contents of the discharged container to retain its status or status as it passes from the container to / from the bag-forming shed / bag forming mandrel.

[0065] Applicants have found that the slow moving gate 72 reduces the density of the blank, while the fast-acting shutter 72 allows the semi-finished product to remain compacted. The fast-acting valve 72 used here is a valve that fully opens in less than 50 milliseconds. There are various ways to minimize the effect that the gate valve 72 has on compacting the blank. In one embodiment, the shutter speed 72 is increased. In another embodiment, the valve 72 is fully open in just about 40 milliseconds. As mentioned, this fast-acting valve 72 operates to minimize the drop in compaction. In one embodiment, the length of the valve 72 is increased. This allows to increase the speed of the valve 72 before opening the opening 92. Furthermore, as shown, the valve 72 and the opening 92 are arranged so that the shortest distance in the opening 92 is in the same direction in which the valve 72 is opened. The fast-acting valve 72 can be implemented in any device described herein.

[0066] In particular reference now to FIG. 14 and 15, two preferred non-limiting actuated turret bows 32, 132 are shown, namely assemblies for producing "large" (FIG.14) and "small" (FIG. 15) embedded and formed measured portions. As previously stated, changing the mass of a measured portion for packaging is not uncommon when processing a product. As can be seen from the review of the shelves of the grocery store, different sizes of packaging are available, ranging from packages provided for one person to several items in a package to the size of bags for "family" or "for adoption". By means of a modular approach, one actuated turret assembly can easily be exchanged for another actuated turret assembly or, alternatively, it is contemplated to replace or modernize the containers of a given assembly for adaptation to various production purposes. Before presenting the details of the actuated turret assemblies of FIG. 14 and 15, namely the characteristic details with respect to their product / deposition containers and molding containers, some general observations are justified.

[0067] Numerous containers 40, 140 for depositing / embedding the product and forming are generally shown with the delineation of the axis of rotation, namely the axis corresponding to the axial center line 88 of the rotor drive shaft 48 of the turret assembly. Containers for embedding the product / deposition product and forming a preferred device can be properly characterized as vertical tubes or vertically oriented sleeves (i.e., structures having "open" top and bottom). Each container or tube is characterized by an inlet portion 90, 190 of a metered product portion and an output counterpart 92, 192 of the deposited portion of product mounted, and can be properly characterized as having an axially extending centerline 94, 194. Preferably, but not necessarily, the cross-sectional area of ​​the container is substantially larger towards the outlet part from the entrance part (e.g. the entrance part of the deposition / deposition chamber and the constriction tapers towards its outlet part from the entrance part). Similarly, the maximum dimension of the container or container generally increases towards the outlet part from the entrance part. Furthermore, the containers are preferably configured to be properly characterized by a cross-section selected from the group consisting of circular, oblong or oval, although other cross-sections may be preferred. the maximum dimension of the container or container generally increases towards the outlet part from the entrance part. Furthermore, the containers are preferably configured to be properly characterized by a cross-section selected from the group consisting of circular, oblong or oval, although other cross-sections may be preferred. the maximum dimension of the container or container generally increases towards the outlet part from the entrance part. Furthermore, the containers are preferably configured to be properly characterized by a cross-section selected from the group consisting of circular, oblong or oval, although other cross-sections may be preferred.

[0068] In a further and general reference to FIG. 14 and a particular reference to FIG. 8, it should be noted that circumferentially spaced containers 40 should be inclined in the body 42 of the turret assembly. The bulk containment and forming containers are circumferentially disposed in the turret-tool body 42 such that the offset angle θ is determined by cutting the extension axis 96 for each massive receiving and forming container with a beam 98 connecting the axial center line of the revolver tool assembly (i.e. the axial center line 88 of the shaft 52) ​​and the center point of the extension axis 96 (i.e., the aforementioned axially extending centreline 94 of the container 40).

stopped or rapidly stopped), when rotating from a place of filling with a metered product to the place of discharge of the deposited and formed measured product (i.e., "pouring" the product due to centrifugal forces / inertia changes, if not eliminated, it is significantly and preferably reduced). It should be noted in the light of the above that the details of the turret assembly of FIG. 14, and more precisely, the containers and their arrangement in the assembly, facilitate the formation of an embedded and formed measured product for subsequent packaging. Although it is believed that an offset angle θ up to about 45 ° could be sufficient to achieve a particular purpose, it is considered that an offset angle θ in the range of about 20-40 ° is preferred.

[0069] Referring again and particularly to FIG. 15, a plurality of deposition / molding sleeve 140 depositions characterized by a substantially circular cross-section are shown to be circumferentially spaced about the rotation axis of the turret assembly. Bushings 140 as shown generally include a segment or upper portion characterized by a distinctly decreasing cross-sectional area, in particular and preferably the inlet portion 190 of the deposition / deposit forming sleeve 140 includes a funnel-free end, e.g. a metered container 189 that receives at least a pre-measured metering. portion of the product. Subsequent actuation of the turret assembly 132, e.g. indexed rotation, resulting in subsequent or sequential movement and retention of the pre-charged bushing, carries at least a portion of the pre-metered portion from the reservoir 189 to the sleeve segment 191 with a reduced and generally decreasing formed cross-sectional area that includes the output portion 192. By selectively activating the actuated rotary head assembly 132, prior to discharge or exit of the contents to be packaged, embedded and the measured portion of the product causes a reduction in the diameter of the sleeve. Preferably, but not necessarily, the cross-sectional area of ​​the inlet portion (i.e., the metering container 189) is in the range of about 1.25-2.5 times greater than the cross-sectional area of ​​the outlet and / or forming portion of the deposited portion. By selecting the actuation of the rotary head assembly 132 to be started, prior to discharge or exit of the contents to be packed, the embedded and measured portion of the product causes a reduction in the diameter of the sleeve. Preferably, but not necessarily, the cross-sectional area of ​​the inlet portion (i.e., the metering container 189) is in the range of about 1.25-2.5 times greater than the cross-sectional area of ​​the outlet and / or forming portion of the deposited portion. By selecting the actuation of the rotary head assembly 132 to be started, prior to discharge or exit of the contents to be packed, the embedded and measured portion of the product causes a reduction in the diameter of the sleeve. Preferably, but not necessarily, the cross-sectional area of ​​the inlet portion (i.e., the metering container 189) is in the range of about 1.25-2.5 times greater than the cross-sectional area of ​​the outlet and / or forming portion of the deposited portion.

[0070] Referring now to FIG. 15A, a portion of a further alternative deposition embedding / forming sleeve is shown, namely the metering reservoir 189 '. The reservoir has an entrance 190 'properly characterized as triangular with rounded corners. With respect to its arrangement in the turret assembly, the "nose" of the reservoir is intended to be directed to the axial center line 88. The cone is characterized by the transition from the reservoir 189 'to the portion of the embedded portion of the sleeve which includes the exit part (not shown). The lower part of the tank sleeve 189 'can be configured to have an oval cross-section, which should be appreciated with respect to the lower part thereof, however, this part is not intended to be such a limitation.

[0071] Referring now to FIG. 16 and 17, considerate deposition systems of a metered product are shown in combination with product transfer means, namely an improved bag forming device or bag forming mandrel 60, 160 (referring also to FIG 18, and generally FIGS 4 and 6). By following the above detail, the combination of FIG.16 is characterized by the turret assembly of FIG.14, while the combination of FIG.17 is characterized by the turret assembly of FIG. 15, and more precisely, the containers / sleeves receiving the metered portion respectively. FIG. 14 and 15. As indicated, the cross section of the bag forming mandrel generally mimics the cross-section of the output part of the product deposit containers, e.g. longitudinal (FIG.14) and circular (FIG. 15).

[0072] With respect to bag forming mandrel 60, 160, it is properly characterized as a sleeve that defines a clearance 63, 163 for receiving and passing, in this description, a deposited and formed measured portion of product. Although not shown, support of the mandrel or provision of a gas-introducing pipe (s) or similar is contemplated to facilitate the introduction of a portion of gas, e.g., nitrogen, into the product package prior to closure. The mandrel 60, 160, and more specifically the sleeve as shown preferably includes at least an elongated segment with through-passages. Provided that perforations or holes 65, 165 are shown, the transitions do not have to be so limited. As part of the processing of the film to form the film sleeve / bag around the mandrel, operations forming the sack, namely, a transverse sealing / sealing cut to form the closed top and bottom portions of the bag sleeve so as to define the top / bottom of the bag results in air displacement in the stem lumen in the upward direction (i.e. in the direction of forming the metered portion). The mandrel containing a perforated or otherwise de-aerated tube or sleeve / sleeve segment allows an inevitable counter-current "rising current" to cause a short-circuit before encountering to sever the under-pressure of the falling portioned and shaped measured product so that the condensed portion remains substantially compacted. in the direction of forming a measured portion). The mandrel containing a perforated or otherwise de-aerated tube or sleeve / sleeve segment allows an inevitable counter-current "rising current" to cause a short-circuit before encountering to sever the under-pressure of the falling portioned and shaped measured product so that the condensed portion remains substantially compacted. in the direction of forming a measured portion). The mandrel containing a perforated or otherwise de-aerated tube or sleeve / sleeve segment allows an inevitable counter-current "rising current" to cause a short-circuit before encountering to sever the under-pressure of the falling portioned and shaped measured product so that the condensed portion remains substantially compacted.

[0073] Referring now to FIG.18, a perspective view of a further filling device using a deposition chamber and openings for releasing a vacuum is shown. FIG. 18 is similar to FIG. 6 except that FIG. 18 also illustrates the openings for releasing the vacuum 65 in a portion of the bag forming mandrel 60. FIG.18 illustrates a deposition device 30 located downstream of the weight 23 and upstream of the product delivery cylinder 60, wherein the product delivery cylinder 60 includes a forming collar 27 and the product delivery cylinder 60 includes openings 65 for releasing a vacuum located above the molding flange 27. As mentioned in one embodiment, the condensed product blank is formed before the product is assembled in the product delivery cylinder. As mentioned before, this compacted blank creates a negative pressure in the product delivery cylinder 60 as it descends in the product delivery cylinder 60. This was not present in the prior art, because the product was characterized by sufficient spreading to prevent the formation of underpressure. In addition, there was no sliding gate 72, air flow, and thus produced

However, the compacted blank does not create a vacuum over the blank in the product delivery cylinder 60 when the product delivery cylinder 60 is sealed. In one embodiment, the product delivery cylinder 60 is sealed when the valve 72 in front of it is closed. This negative pressure reduces the speed with which the semi-finished product can fall. In order to minimize the negative pressure created, the openings 65 for releasing the vacuum are positioned above the forming flange 27 which directs the packaging material. The openings 65 for releasing the vacuum allow the air to enter the product delivery cylinder 60 and interrupt the vacuum. The openings 65 for releasing a vacuum may include one orifice or may include two or more openings. In one embodiment, the holes are 1/8 inch 1/4 inch.

[0074] In one embodiment, the openings do not start on the first three inches of the product delivery cylinder 60. Applicants have found that certain products comprising edges or corners may engage apertures 65 and thereby interfere with the flow of the product. To overcome this problem in one embodiment, the product may gain momentum in the product delivery cylinder section 60 that does not include holes before entering the product into the product delivery cylinder section 60, including holes 65. In another embodiment, the holes 65 are dimensioned to minimize capture through the openings 65. As shown, FIG. 18 does not include an intermediate funnel 99, however, other embodiments include an intermediate funnel 99. This intermediate member allows the product to gain momentum,

[0075] Vacuum relief openings 65 may be implemented in any sizing machine comprising a product delivery cylinder 60 that includes a collar 27. In one embodiment, the bag making machine comprises a vertical, forming, filling and sealing machine for making sacks, containing the weight and cylinder of product delivery.

[0076] In re-reference in general to the example of FIG. 6-11, another embodiment of the invention will now be discussed. In one embodiment, the discharge chamber 40a is monitored by a sensor. The sensor may comprise any known sensor of the prior art. In one embodiment, the sensor includes a digital or analog sensor. In another embodiment, the sensor includes a photoelectric sensor. As an example, in one embodiment, the sensor is located above the discharge chamber 40a. The sensor can determine the presence of the product in the chamber, which would indicate that not all of the product has left the discharge chamber 40a. In such a state, a poker can help in cleaning the discharge chamber 40a from the remaining product. The poker can contain any mechanical device, which can forcefully remove the product from the chamber. In one embodiment, the poker device includes a mechanical rod that forces the output of the product out of the chamber. In another embodiment, the poker includes a piston that forces the output of the product out of the chamber. In another embodiment, the poker includes a blast of air, nitrogen, etc. to force the removal of the remaining product from the discharge chamber 204a. It should further be noted that the sensing and mixing functions can be easily associated with the various embedding / deposition / forming approaches considered, previously or sequentially discussed and considered. In another embodiment, the poker includes a blast of air, nitrogen, etc. to force the removal of the remaining product from the discharge chamber 204a. It should further be noted that the sensing and mixing functions can be easily associated with the various embedding / deposition / forming approaches considered, previously or sequentially discussed and considered. In another embodiment, the poker includes a blast of air, nitrogen, etc. to force the removal of the remaining product from the discharge chamber 204a. It should further be noted that the sensing and mixing functions can be easily associated with the various embedding / deposition / forming approaches considered, previously or sequentially discussed and considered.

[0077] The poker can be located on the discharge chamber 40a or can be adjacent to the withdrawal chamber 40. Furthermore, in connection with the containment containers or chambers characterized as a reservoir, it is considered advantageous to provide mixing associated with both the reservoir and its portion of the deposited portion (see e.g. chambers from FIG. 15 / 15A). In one embodiment, the poker is located above the discharge chamber 40a and can be configured and / or actuated to "nudge" the product in the chamber or chamber or the poker can be configured and / or actuated to move up and down, through at least the upper part of the chamber. In one embodiment, the poker is actively coupled to the sensor. The expression actively coupled used here refers to the device, which receives a signal from another device. Thus, the poker receives the signal either directly or indirectly from the sensor. Finally, while sensing or on-demand functionality is contemplated, the start of the poker can also be simultaneous with said drain cycle, i.e. rather with a set operation than the selected one.

[0078] Referring now to FIG. 19-21, the attention is particularly directed to the structural departures of selected components, structures and / or elements of the embedding apparatus 30 (e.g., that of FIG. 7). Before providing further details, it should be noted that a part of the base 34, see e.g. FIG. 7, does not appear in FIG. 19 to facilitate the view of structures / features that would otherwise be invisible from the "top". Furthermore, while FIG.20 is a bottom view of the apparatus of FIG. 19, which inter alia illustrates operationally positioned bag forming means for the bag forming / filling station, FIG.21 shows a detailed view as FIG.20, but without bag forming means forming bags / sacks to make it easier to view structures / features that are otherwise invisible. [0079] In this embodiment, the body 42 of the assembly u includes selectively configured body plates of the assembly, and more specifically the stylized upper 44 'and lower 46' of the assembly plate, which could be properly characterized as 'star wheels'. Generally, the plates comprise U-shaped circumferential "notches" 45, the "legs" extending outwardly, i.e. away from the axial centerline 88. Although the hub and the spoked-wheel system or wagon wheels are illustrated, the distribution is also considered commensurate with the offset the arrangement of the containers of FIG. 8 or 10. [0080] While the illustrated peripheral profile of the plate is responsible for direct reception in the U-shaped recess of the associated receiving container packaging, indirect reception of various alternatively dimensioned and / or configured containers is contemplated. Accordingly, one or more & quot; assemblies & quot; of alternatively configured sleeves such as sleeve 47 & quot; of the first set of sleeves is provided to allow fast, easy collection and maintenance of the panel through a wide variety of different container configurations to settle. In the sleeve shown, the hole 101 is positioned adjacent to the rear end or edge 103 of the sleeve 47 to receive and retain a portion of the receiving container 40, e.g. as shown in the container segment 191, while the funnel end or reservoir 189 is selectively spaced by such a configuration of the sleeve. from the axial centerline 88. The "upper" and "lower" sleeves for each container as shown are in turn readily received and reliably maintained by the assembly body panels, and more specifically by each of the U-shaped perimeter cutouts.

[0081] In order to reduce processing time or line downtime, additional features should be noticed. Namely, fast and reliable reverse releasing of the assembly characterized by terminals 105 (e.g. FIG. 20) is ensured for the reversible retention of the bag forming mandrel (FIGS. 20 and 21) and the hatch 107 to allow passage of the receiving container into and out of the turret assembly body. from the bottom.

[0082] It should be appreciated in view of the contrasting views of FIG. 20 and 21, that the base 34 of the turret includes a passage in the form of a bore or cut-out 58 to allow / facilitate the exit of a generally-deposited, formed (s)

the deposited metered product portions from the deposition station, forming the deposition into a bag manufacturing and packaging station (see FIG. 5). As illustrated, a portion of the aperture 58 is traversed, traversed, or otherwise covered to selectively discharge a deposited product portion from a settling vessel, e.g., a gate 72 (FIG. 19), which as previously described is rapidly switched between the first and the portions. a second operative position to allow passage of the deposited product portion to and through the underlying bag forming mandrel by means of the protected / valve portions of the opening. In connection with the arrangement of FIG. 19, the valve is in the output blocking setting with respect to the hole 109 of the plate 111 with the hole retained at the bottom 70 of the base 34 of the turret (FIG. 20,

[0083] Adjacent to the valve from the top and the plate with the hole at the bottom, and thus substantially defined in this way (FIG 19 and 21 respectively) is the "remaining part" of the hole (i.e., part of the hole not covered by a valve / plate with an opening), which serves as a hatch or access point (FIG.20 or 21) to facilitate selective exchange of the settling chamber or its conversion to other production. More specifically, as will be appreciated after checking either FIG. 20 or 21, the passage of the canister of settling by the base 34 of the turret to be fixed in the plates of the assembly body is possible through the hatch.

With regard to a preferred operation sequence, the turret assembly rotates. [0084] Which is selectively operated relative to the base of the turret and located above the measuring station.

More specifically, the indexed rotation run occurs relative to the position / exact filling point defined by the metering station and the position / exact place for emptying designated by the turret's base. Preferably, the metered product will be collected at the loading station and released at the discharge station at approximately the same time.

[0085] When the "X" pipe from the total "N" of the pipe of the assembly is set to empty at the emptying stand, the "x + 1" pipe is preferably arranged for pre-filling at the filling station near the drain station, and the pipe " x + 2 "has passed the initial deposition / compaction repetition and pipe" x-1 "goes to the" on board "setting for emptying (ie next in the queue for emptying). The indexing occurs each time an embedded and formed measured portion of product is discharged from the turret assembly into or into the funnel / forming machine for making the bags, preferably the clearance of the ventilated tube as in FIG. 16 or 17, with several portions of the measured product introduced into the turret assembly through the commissioning cycle.

[0086] For the largest and largest sizes of the bag (s), it is advantageous if seven or eight containers / tubes are maintained in the body of the turret assembly that peel the measured portions of the product, once / in sequence, from the measuring station. The number of sleeves or tubes is variable, a function of, inter alia, the type of product to be processed and the purposes of processing the product, for example, the quantity or number could also be doubled if small sacks were considered. Inserted or replaced containers could be used, through a conversion and juxtaposition approach, to achieve one or more alternative product processing purposes.

[0087] When the tool turret rotates, it deposits the product in the tool turret by quickly stopping and restarting the one-way traffic. While the traffic under consideration is "start / stop" and the traffic is a one-way rotation, it does not have to be so limited. For example, inertial changes are generally considered satisfactory in assisting and / or performing deployment operations, e.g. changing the turret speed or acceleration, and cyclically working the revolver assembly back and forth, either by rotating the forward or rearward assembly of the set here or by bi-directional movement through a modified or alternatively configured turret assembly are also considered options.

[0088] Thus, because the steps, assemblies and / or process constructions, packaging-related systems and devices disclosed herein can be made in other specific forms without departing from the idea of ​​the invention and its general features, some of which are indicated, and features described and presented here should be considered in all respects as illustrative and not restrictive. Accordingly, the scope of the disclosed invention is defined by the language of the appended claims and includes versatile non-negligible equivalents.
