Device for sticking boxes (versions) and method of producing boxes

TECHNICAL FIELD

The present invention relates to the production and manufacture of packaging materials.

BACKGROUND

In the industrial products manufacturing corrugated cardboard using many different devices that convert a cutting from a corrugated cardboard carton blank into a finished box. Some of these devices can perform the cutting, causing the fold line folding and (or) gluing blanks made of cardboard in order to obtain the finished box. Adhesive machine is often one of the elements of the group consecutively installed machines, turning blanks made of corrugated cardboard boxes in one. This adhesive apparatus usually takes the folded blank with four adjacent walls, separated from one another by longitudinal fold lines and slits. Each of these walls also includes oppositely located flaps that can be folded so as to receive the upper and lower face of the box. Also it is always one of the walls has a tab for gluing. The adhesive glue is applied to the device for the adhesive tab and (or) to the nearest wall and presses the tab for the adhesive to the nearest wall, this gives a box with four connected parties.

Typical adhesive devices are relatively complex and large machines. These machines are often equipped with a conveyor belt for transporting pieces of corrugated cardboard through the machine. Typical adhesive apparatus also includes a device for applying the adhesive, which can be mechanically moved along the workpiece made of corrugated cardboard and put glue on the adhesive tab. In addition, many devices are adhesive device for applying pressure to the adhesive tab (e.g., pneumatic manipulator) which are intended for connection with an adjoining adhesive tongue wall box. Because of the complex structure of typical machines for bonding and the need for proper synchronization of the device glue and other moving parts glue machines often are equipped with computers or other electronic devices for controlling the operation of various parts of the machine and preventing their impact at work. For example, a computer or other electronic device can coordinate intervals and to control the operation of one or more pneumatic manipulators intended for folding the blank, the device glue for applying glue to the blank, and a pressing device for applying pressure to those parts of the workpiece for which the adhesive is applied, so that none of these components are not disturb other. The complex nature of the adhesive devices having a plurality of moving parts and electronic devices increases the cost of cars and often requires significant operating costs and maintenance costs.

In addition to the relatively complex structure of typical adhesive devices, they often have impressive dimensions. The blank of corrugated cardboard glued together model glue machine, usually bent in such a way that the adhesive tab comes out of the middle of the workpiece. Thus, all the devices have a large adhesive C-shaped frame. The lower part of the frame supports the blank of corrugated cardboard in the process of bonding. The upper part of the frame carrying the application device adhesive is placed over the top of the corrugated cardboard blanks at a location that allows to control the adhesive tab located in the middle portion of the workpiece. For larger pieces should be used with cell phones glued frames even larger. Such large glue machines can take up valuable space in the production or other types of industrial facilities.

Subject of the present application is not limited to the embodiment which avoids faults or work only in an industrial environment, as described above. It will be more emphasized that these conditions are given only to illustrate only one exemplary technology area where variations in the design described herein can be applied.

In Fig.1-13, and in the following text gives a brief and general description of exemplary designs that allow to implement the subject invention. Although the description that is given below machines for gluing a cardboard packaging, it is merely one example, while the structure of the invention may be implemented with other types of glued objects. Therefore, in the specification and claims, the term "glue object", "glue Element", "packaging material", "carton blank", etc. may be used to refer to virtually any type of items which can be glued together as described herein via the system or apparatus.

Figure 1 shows a general sketch of an exemplary structure 100 for bonding machines intended for gluing the blank. For clarity, the bonding machine 100 in Figure 1 is shown with an open lid 103. The machine 100 may operate as an open and a closed cover 103. The bonding machine 100 comprises an outer shell 102, cap 103 and base plate 132, on which in the gluing process is a packaging material. As shown, the bonding machine 100 is located on the support structure 130 (such as a desk) equipped support legs 134. The support plate 132 may be integrally formed with supporting structure 130 or 102 with the outer casing of the machine 100.

Adhesive apparatus 104 for applying glue to the glueing unit, and stored within the outer casing 102. The apparatus 104 for applying adhesive is mounted to the mounting bracket 106 which is movably attached to the rail structure 108 so that the device for applying the adhesive 104 may be selectively moved between a first and a second position on the support structure to provide a gluing along a length of at least one surface of the adherend member. Gluing machine 100 is also equipped with a reservoir for the adhesive 114 (e.g., a reservoir for the molten adhesive) connected with the device for feeding adhesive 104 through conduits 116, 118 and 112 and flexible hose 110.

Device for bonding 100 is also provided with a number of switches 124a-124e, which can be used to change the mode of the device 100, such as a manual mode in which the operator manually starts the bonding process, an automatic mode in which the device 100 may automatically run the unit for bonding after the workpiece is inserted into the device 100. In addition, there is a foot pedal 120 connected to device 100 cable or conduit 122. The pedal 120 may be used to start the bonding process in the manual mode. After the packaging material is glued and (optionally) are stacked, the unit can begin the next gluing packaging material in a similar manner.

Referring to Figure 2, which depicts an example of a corrugated cardboard blank 200, which may be glued using the machine 100 described herein and shown in the drawing. A carton blank 200 has four walls near (202a-202d), and an adhesive tab 206. The walls 202a-202d and glue tab 206 are separated by longitudinal fold lines 208a, 208 and 210 respectively. In addition, each side has a transverse incisions 212a-212h and the slots 214a-214f, which determine the position of opposing valves 204a-204h. Opposing valves 204a-204h are formed so as to receive the top and bottom of the box. Longitudinal and transverse fold lines (208a-208c, 210, and 212a-212h), the slots 214a-214f and the adhesive tab 206 can be performed using the cutting machine, Creaser and (or) using a stamping press. Alternatively, it will be described in more detail below, fold line 210 disposed between the adhesive tab 206 and the wall 202a may be formed by the machine for bonding.

By means of longitudinal and transverse fold lines (208a-208c, 210, and 212a-212h) and of the slots 214a-214f, 200 made on the workpiece, the workpiece may be folded along fold lines 208b, as shown in Figure 3, and an adhesive tab 206 can be attached to the adjacent wall, which allows to obtain a box 200a. Based on the reasons that will be described below, note that the carton blank 202a in the form in which it is folded and glued (see Fig. 3), the tab has an adhesive 206 disposed on the edge 200a of the box, and not in the middle. Also note that glue tab 206 located on the outer side of the adjacent wall 202d, rather than on the inner side wall 202d.

4 shows another embodiment of a carton blank which is divided into two separate parts 300a and 300b, which are glued together to form the box. Part 300a preform has two walls 302a-302b, and the adhesive tab 306a. Similarly, the portion of the workpiece 300b has two wall 302c-302d and the adhesive tab 306b. Side walls 302a-302b, and the adhesive tab 306a separated by longitudinal fold lines 308a and 310a, respectively. Similarly, the side walls 302c and 302d-adhesive tab 306b separated longitudinal fold lines 308b and 310b, respectively. Furthermore, each of the side walls 302a-302d includes a transverse fold lines 312a-312h and slots 314a-314d, which define oppositely-located valves 304a-304h, which are formed by folding the top and bottom of the box. Longitudinal and transverse fold lines (308a-308b, 310a-310b and 312a-312h), the slots 314a-314d, and glue the tabs 306a-306b may be performed using Creaser-cutting machine, and (or) with the die-cutter. Alternatively, as will be described in more detail below, the fold lines 310a-310b, located between the adhesive tabs 306a-306b and the walls 302a and 302d, may be formed by the device for gluing.

As shown in Figure 5, to receive a box 300c, the two halves of blanks for boxes 300a and 300b can overlap one another with two adhesive tabs 300a and 306b on opposite ends. In the first step bonding adhesive tab 306a may be attached to the corresponding wall 302c using machines for gluing as described herein. In the second stage the two halves of the box for bonding 300a and 300b, which are now connected between the adhesive tab 306a and the wall 302c can be removed from the apparatus, rotated through 180 ° to the other side and are inserted into the apparatus again so that the adhesive tab 306b was glued to the respective adjacent wall 302b.

Referring to Fig.6-13, which shows the various types of devices for bonding in accordance with various embodiments of the present invention.

6 shows a perspective view of an apparatus for bonding structure 100 when the blank 200 located on the support structure 130 for bonding. Furthermore, in order to show the scale of the figure shows a 600 operator.

Referring to Figures 6 and 7, which further fragments are views of the machine 100 in context. As mentioned when referring to Figure 1, the machine for bonding 100 has an outer housing 102, the cover 103 and support structure 130 (e.g., countertop) with support feet 134. The adhesive 104 is apparatus for applying glue to the blank 200 and stored in the inner casing 102 . Adhesive unit 104 mounted on a bracket 106 which in turn is attached to a system of rails 108 so that the adhesive device 104 can be selectively moved between a first and a second position on the support structure and to apply the adhesive along the length of at least one end face adhesive preform 200. Moving the device 104 from the first to the second position indicated by the arrow 144. The device 100 also has an adhesive tank for the adhesive 114 (e.g., hot glue) which is connected with an adhesive device 104 tubes 116, 118 and 112 and flexible hose 110 . The hose 110 has such a form as to avoid entangling the tubes 112 as you move the adhesive unit 104 back and forth.

Device for gluing 100 also has a number of switches 124a-124e, which can be used to change the mode of the device 100, for example, to switch to manual mode in which the operator manually starts the bonding process, the automatic mode, where the device 100 may automatically start the machine bonding after the preform is inserted into the device 100. In addition, there is a foot pedal 120 connected to machine 100 cable or conduit 122. The pedal 120 may be used to start the bonding process in the manual mode. After the packaging material is glued and (optionally) are stacked, the unit can begin the next gluing packaging material in a similar manner.

Moreover, as seen from the sectional drawing shown in Figure 7, the apparatus 100 for bonding has several drive pistons (e.g., 142 and 170) and a quantity of driving levers (for example, 140) that can be used to drive the clamp arms (e.g. , 136 and 138), as well as other devices for folding and gluing when the blank is folded 200. Devices intended for gluing and folding the blank 200 will be described in more detail below when taken 8A-13.

Referring now to Figures 8A and 8B, which show cross-sectional views of the machine 100 along lines 8A-8A and 8B-13-8V-13, previously shown in Figure 7. 8A and 8B, the carton blank 200 is aligned and supported on the support structure 130 to perform the bonding apparatus 100. Bonding apparatus 100 is provided with several mechanical structures that are designed for applying adhesive to the blank 200 folding and adhesive bonding of the tongue 206 on the adjacent wall 202d preform 200.

The apparatus 100 is provided with a first tack 156 for selectively and securely retain the first portion of the workpiece 200 (e.g., tab 206) on the base plate 132 and the second tack 136 and 138 for selectively and securely retain the second portion of the workpiece 200 on the base plate 132. As shown in Figures 8A and 8B, first and second are stuck in the top position.

Installation 156 is monitored sticking second lever 156 and the piston 160 are connected together and to the first tack 156. Set 156 may be stuck by extending piston 160 (to the upper position) or the compression piston 160 (to the lower position). Similarly, the installation of the second sticking 136 and 138 by a lever 140 and a piston 142 (see. Figure 7). In the process of bonding the first and second clamps 156 and 136/138 can move upward so that the workpiece 200 can be inserted into the machine 100, and down to secure the workpiece 200, and then again upwards to release the workpiece 200 after the adhesive agent, and remove it from the machine 100. Such a cyclical movement of sticking and bonding process can be run automatically by setting the workpiece 200 in the machine 100, or manually by the operator.

Furthermore, at least one support plate 132 of the device 100 is provided with means for alignment, such as a guide rail, a stopper leveling protrusion tags, sensors or other means for equalizing providing a proper positioning of the workpiece 200 on the base plate 132 so as to apply adhesive to the desired portion of the workpiece 200. According to one embodiment, shown in Figures 8A-13, as the means used for aligning the partition wall 154 installed in the device 100. When setting the workpiece 200 into the latch 206, 100 aligned via the partition wall 154 in such a manner that the tab 206 and the workpiece 200 will be ready for gluing and folding. Thus, the user can quickly, easily and accurately install the preform 200 on the base plate 132, without having to visually check the position of the workpiece 200. The partition wall 154 also has a number of notches 155 ensuring sticking cyclic movement up and down in the gluing process. Anyone familiar with the technique, it is understood that the alignment means may have very different shapes without departing from the subject of the present invention.

The apparatus also includes a glue unit 104 coupled to the glue supply system (e.g., 144 in Figure 6) through a conduit 112. The glue apparatus 104 includes housing 105 and the dispensing nozzle for the glue, consisting in turn of the proximal portion 146 connected to the body 105 and distal portion 148 projecting toward the carton blank 200. In the example shown in the drawing, the adhesive device 104 is movably mounted in the device 100 on the rails 108 by means of several wheels 107 so that the adhesive unit 104 may selectively move between the first and the second position and to apply the adhesive along the length of at least one end face of the carton blank 200.

Management gluing using dispensing nozzles 146/148 may be different variants of mechanical devices. For example, after the carton blank 200 is positioned so that the dispensing nozzle for the glue 146/148 was next to tab 206, the operator of the machine for bonding can turn on the glue nozzle 146/148 using the buttons, switches, pedals, etc. (e.g., pedal 120) to begin applying the adhesive to the workpiece 200. After applying the required amount of adhesive on the tab 206 and (or) to the adjacent wall 202d operator can deactivate the adhesive dispensing nozzle 146/1448, using the same or other control device ( button, a switch, a pedal and the like)

In one embodiment, the sensor 150 for detecting the presence of an object in the bonding machine 100 operatively connected to an adhesive unit 104. The sensor 150 shown in Figure 8A in the form of an infrared sensor detecting the presence of the workpiece 200, installed in the machine. The infrared beam sensor 150 is shown schematically callout 152. Once the sensor detects the presence of the preform 200 or other adherend object beneath the nozzle device 100 146/148 sensor starts the supply of adhesive glue machine. For example, if the preform 200 is under the glue dispensing nozzle 146/148, adhesive apparatus 104 starts to move horizontally from the first position to the second. The sensor 150 may be positioned such that the adhesive unit 104 starts to supply the adhesive only when the nozzle 146/148 is over the workpiece 200. This prevents the unwanted flow of glue adhesive machine at other times. Although herein described system of the infrared sensor, it is understood that possible installation of any other optical, electronic and mechanical sensors (e.g., laser sensors, photodetectors, motion detectors, proximity sensors, cameras, ultrasonic sensors, sonar, radar, a mechanical stylus, or any combinations of these devices) for detecting the presence of an object in the car adherend and application of the adhesive to the desired portion of the object.

In one embodiment, the sensor 150 may be coupled with an automated system that detects the presence of the workpiece 200 and automatically delivers the command to the device 100 for supplying glue to the glue tab 206 and (or) the wall 202d. This automated system may also determine that the tab and (or) coated on the wall if necessary amount of glue or that the tongue and (or) the workpiece is not under the nozzle. In both cases, the automated system will disable dispensing nozzle for glue and stops supplying the adhesive from the nozzle.

The apparatus also includes bonding the folding device designed to fold the glue tabs 206, 200 on the workpiece outer wall portion 202d adjacent blank 200. Crease apparatus is configured such that it bends the adhesive tab to the wall after gluing at least one outermost surface adhesive tab or wall.

Crease unit includes one zagibatel 162, which provides lifting, smoothing and folding of adhesive tab 206 to the adjacent wall 202d of the first workpiece 200. Installing zagibatelya 162 is made by at least one mechanical drive (piston 164), which picks up and smooths bends adhesive tab 206 on the rear wall of the first 156 stuck, and after getting stuck first zagibatel first 162 bends the adhesive tab 206 on the adjacent wall 202d workpiece 200. Crease unit is also provided with a second zagibatelem 166, which is under the distal end of the workpiece 200, while the first 162 zagibatel bend tab 206 . fitting of a second zagibatelya by a lever 168 and at least one mechanical actuator (e.g., piston 170).

Second zagibatel 166 supports a support plate 132 for the distal end of the workpiece 200. In this second zagibatel 166 supports a support plate in the gluing process and prevent deflection of the support upon the application of a bending force 162. Second first zagibatelem zagibatel 166 is also designed to enhance the efficiency of folding in the first zagibatelem 162 as a spacer wedge clamp for clamping and glue tab 206 to the adjacent wall 202d preform 200. This arrangement of first and second zagibateley 162 and 166 allows the use of rigid materials in the manufacture of the first and second zagibatelya 162 and 166 and the base plate. It also allows the use of fewer and less rigid internal structures in the machine 100, because the device 100 presses one end of the workpiece 200 and makes the seam, instead of having a lever which must reach the middle of the box.

In accordance with another embodiment of the invention, the first and second zagibateli 162 and 166 are separately disposed and actuated separately, at least one mechanical actuator (e.g., piston 164, and 170) which provide a cyclic sequence of movements of the first and second zagibateley 162 and 166 in the gluing process. In accordance with another embodiment, the first and second zagibateli 162 and 166 are separately disposed and are driven by multiple mechanical drives (e.g., pistons 164 and 170) which provide a cyclic sequence of movements of the first and second zagibateley 162 and 166 in the gluing process. The number of mechanical actuators required for operation is dependent on the size of the car 100 (i.e., the length zagibateley 162 and 166) and rigidity zagibateley 162 and 166. If the device 100 will be small in size and (or) zagibateli 162 and 166 are particularly stringent , it would be enough to have one or two mechanical actuator. However, if the size of the device 100 will be large and (or) a device 100 will have less stringent zagibateli 162 and 166, may require more mechanical actuators to provide the necessary pressure flexion and compression to glue tab 206 to the adjacent wall 202d.

In accordance with one embodiment of the invention, several separated by mechanical actuators are approximately 20-80 cm or 30-60 cm, or preferably 40-50 cm. The driving of the first and second 162 and 166 zagibatelya several mechanical actuators can increase benefits zagibateley 162 and 166 and provide a more uniform pressure along the length of the workpiece 200. In addition, the use of multiple mechanical drives may allow less stringent zagibateli 162 and 166, without affecting their ability to apply a uniform pressure along the length of the carton blank 200.

Referring now to Figures 9-13, which show the other stages of the bending process. 8A and 8B, the discussion of which is given above, a first step in the process of bending, wherein the workpiece 200 is inserted into the device 100 and its presence is fixed sensor 152. Figure 9 shows a second step in the process of bending.

In the second step, the first and second clamps 156 and 136/138 are lowered and pressed against workpiece 200 to a base plate 132. The first sticking 156 holds at least one preform layer 200 beyond the distal end thereof. For example, a first sticking 156 may fall down on the adhesive tab portion 206 by fold line 210 and to press the tongue 206 during bonding and adhesive has been applied to the workpiece 200 to bend the tab 206. In another example, a first sticking 156 may create a fold line 210 tongue 206. In still another embodiment, the first can 156 sticking down on the adjacent wall portion 202d so as to hold the wall 202d and a tongue 206 in the process of applying the adhesive, and bend the tab 206 after applying the adhesive. The second sticking 136/138 holds at least two layers of material of the box. For example, a second sticking 136/138 can be lowered onto the upper wall portion 202c, and (or) 202d, which will be located under the walls 202a and 202b, respectively. Thus, the second nip 136/138 200 may hold the workpiece in place on the base plate 132. While the workpiece 200 is held firmly in place the first and second tacks 156 and 136/138, the adhesive unit 104 may apply the adhesive (e.g., a drop of glue is schematically depicted callout 172), at least on the adhesive tab 206 or on the outer part of the adjacent wall 202d, which is connected to the tongue 206 after bending.

10-13 shows the steps of bending the adhesive tab 206 on the adjacent wall 202d. In the example shown zagibateli 162 and 166 are designed to fold the glue tab 206 to the adjacent wall 202d workpiece 200 at least in two stages or two steps. The first folding step is shown in Figure 10: zagibatel second adhesive 166 lying under the tongue 206 and the distal end 200 of the box until first zagibatel 162 rises, smoothes and glue tab 206 bends 90 ° towards the rear side of the first sticking 156 which is in the lower position .

As mentioned above, if the first zagibatel 162 rises, it can smooth the glue tab 206 at the rear side of the first well stuck to the adhesive tab was smooth and bend it along the fold line 210. This feature of the present invention is particularly advantageous when the blank 200 It comes from the infinite source of packaging material (such as cardboard), the folded "accordion". It is clear that when applying from an endless source, such as the processing of corrugated cardboard, folded "concertina" fold line or crease in the material is already available.

Fold lines "accordion" may cause some difficulties in the manufacture of boxes from the packing material. For example, if the carton blank is cut from the packaging material folded "concertina" fold line in the material may not coincide with the fold lines used to form the various walls of the preform. In this case, the fold line "accordion" may be at the center of one wall or the tongue. Such fold line "accordion" can lead to the fact that the blank will not lie flat, and the walls and an adhesive tab are not well aligned with the glue applied. In this case, the operator must hold the walls and an adhesive tab in place by gluing tabs.

Jetting apparatus shown in the present invention reduces the disadvantages associated with such fold lines. Since the device for bonding represented in the present invention causes the glue and attaches the adhesive tab when it is located on the edge of the carton blank, the only case where the fold line "accordion" presents difficulties is when this line goes to the center of the adhesive tab. However, the probability of such an arrangement the fold line is extremely low. Wherein the first zagibatel 162 works in conjunction with the first tack 156 and smoothes any crease line, which can be on the tongue because of the addition of material "accordion". Feature is that when the first zagibatel 162 picks up the glue tab 206, zagibatel 162 moves along the rear side of the first sticking the adhesive 156 and bends the tongue 206 up to the rear side of the first 156. The first sticking zagibatel 162 is shifted from the first stuck so that between them fit tab 206 but close enough to prevent the formation of fold lines in the tongue 206, which can lead to buckling or bending. Thus, when the first zagibatel 162 folds the glue tab 206 to the position shown in Figure 10, any fold line "bunching" on the tongue 206 will be straightened so that tab 206 can be glued to the wall 202d.

Figures 11-13 illustrate a second step in the process of bending. As shown in Figure 11, a first sticking 156 moves and lifts the adhesive tab 206. One of the reasons that the tab 206 is bent at an angle of 90 °, shown in this step. If the first sticking 156 rises, the adjacent wall 202d may also have a tendency to rise. However, since the adhesive tab 206 is bent on the adjacent wall 202d, 202d wall can not be raised for the tongue 206. This wall 202d rises and glue tab 206 can engage the wall 202d and press it down in the transition process of bending to the next stages.

Figures 12 and 13, the first adhesive zagibatel 162 holds the tongue 206 on the adjacent wall 202d. After the first 162 zagibatel squeeze the adhesive tab lever 163 connected to the first zagibatelem 162 presses the partition wall 154 and the first zagibatel move down and forward, pressing the tab to the adjoining wall 202d. Similarly, the second zagibatel 166, a raised, working with the first zagibatelem 162 and presses the tab 206 to the adjacent wall 202d. As seen from Figures 12 and 13, first and second zagibatel (162 and 166) are located on opposite sides of the workpiece 200. Such a configuration of the first and second zagibatelya 162 and 166 forms a wedge clamp which presses the glue tab 206 to the wall 202d. It is noteworthy that since the carton blank 200 is glued so that the adhesive tab 206 is located on the edge, not in the center of downforce, which should provide the first and second zagibateli 162 and 166, will be significantly lower than the force that is typically created glue devices with C-shaped frames.

After the glue tab 206 to be smeared with glue and folded onto the adjacent wall 202d, the workpiece 200 can be removed from the machine from the side through which it has been inserted into the machine. In accordance with one embodiment, the adhesive 104 may move the unit back to the first position is performed by the steps of folding the glue tab 206 to the adjacent wall 202d. This allows the car 100 to return to its initial position and to move quickly to gluing these boxes. Thus, when the adhesive tab 206 is folded on wall 202d, the glue unit can move back to the first position (see. Figure 7). Once the tab 206 is bent and attached to the wall 202d and the workpiece 200 is removed from the machine 100, it is possible to insert a different adhesive preform 200 and the machine is ready for the application of glue on it.

As shown above, a plurality of adhesive types of devices are designed to allow folded carton blank of the box so that the adhesive tab located in the middle of the workpiece that requires a large frame which is able to reach the central portion of the carton blank, apply glue to glue tongue and press the tab to adjacent wall. The construction of such a large frame makes it difficult gluing and clamping workpieces. In addition, such large frames take up a lot of useful space. Moreover, the large size of typical machines for bonding increases the time and distance required for handling of the carton blank (machine cutting machine for gluing and the like) as compared with the machines of smaller size.

Apparatus for bonding 100, as described in the present invention has such dimensions and design that it can be placed on a relatively small area, so it can be installed in close proximity to other machines for the production of cartons. This reduces the distance and reduce the time required to produce each box. For example, the device 100 for the bonding represented in the present invention allows the workpiece to bend the tongue mounted on the edge of the workpiece (see. For example, Figures 3 and 5). Apparatus for bonding 100, as described in the present invention eliminates the need for a large frame for applying adhesive on the adhesive tab. More precisely, the device 100 for bonding represented in the present invention is able to apply the adhesive on the blank boxes of any size without the need for adjustment, while having a compact size, allowing it to set relatively close to other devices.

Apparatus for bonding described herein can also be adapted so as to simultaneously glued one or more workpieces. For example, as previously described, the machine can be used for bonding for mounting and gluing a single blank boxes. At the same time it can be adapted for installation and bonding multiple pieces together. Thus, for example, can be installed and secured in position by sticking several blanks. Thereafter, the adhesive may be applied to each of the box blanks and zagibatel used for the simultaneous flanging of all glue flaps multiple workpieces. Furthermore, these blanks can vary in size and individually mounted on a support plate or the preform may be connected to one another so that there is formed a single unit, which will be laid on the baseplate. In the case of connecting several workpieces, they must have such a form that they can be separated after the bonding process. Thus, multiple blanks can be glued boxes in one process, thus increasing the number of frames produced by one time interval.

As indicated above, one advantage of the invention is the fact that it is possible to perform bonding workpieces of different sizes, without changing the configuration or setting device for gluing. For example, the device 100 for the bonding may be used for bonding tongue very large blank by simply inserting the folded part tongue in the workpiece with a device as described above. After the device 100 will be glued large workpiece immediately after harvesting can glue different size using the same procedure. There is no need to re-adjust or re-adjust any of the components for bonding device 100 to operate with workpieces of different size. Thus, the apparatus for bonding described herein allows, according to needs, glued blank of arbitrary sizes directly after one another without downtime associated changeover device.

This feature of the invention distinguishes it from most standard devices for bonding, which require special settings for specific sizes of box blanks. Moreover, most machines are configured for bonding to the processing of blanks of identical size batches. For example, it is possible to adjust the machine for bonding a preform with dimensions 20 × 20 × 20 inches. With these settings you can glue together all parties box blanks, which consist of dozens or hundreds of units. These blanks are stacked and then sent to consumers. For batch processing of workpieces with other dimensions, e.g., 10 × 18 × 6 inches is required readjustment of the machine in accordance with the new size. Thus, every time you want a new size workpieces, it is necessary to conduct such a changeover. In contrast to the above, the device for bonding represented in the present invention is able to apply the adhesive on the blank boxes of any size, in any order, without the need for any re-adjustment.

Referring again to Figures 1 and 8A-13. Adhesive unit 104 is connected to the adhesive supply system 114. As shown, the adhesive delivery system 114 has a reservoir with an adhesive dispensing nozzle connected to tubes 116 and (or) 118 on which the adhesive from the reservoir 114 enters the adhesive unit 104. Tubes 116 and (or) 118 may be any device, which can apply adhesive (tubes, pipes, etc.). Adhesive unit 104 may also have a pump that feeds the adhesive from the reservoir to the nozzle.

Apparatus for bonding 100 may use different types of adhesive. For example, if using hot glue, for instance a thermoplastic adhesive, with the adhesive tank 114 may include a heating element for melting the adhesive. Molten adhesive may then be applied to the adhesive device 104 through the hose 116 and (or) 118. In the device 100 for the bonding may be used and other types of glue: Adhesive for cold gluing resin, polymer adhesives, elastomers, pressure sensitive adhesive (e.g. neoprene) or adhesive curable under pressure.

Although the adhesive unit 104 shown in this embodiment, the machine has a reservoir 114 with the tubes, the device 100 may use other types of adhesive devices 104. For example, the apparatus may be used with rechargeable adhesive cartridges with built glue sticks and a heating element to melt the adhesive. An example of such a device may be a device for applying hot melt 3M Scotch Weld Hot Melt. Such a device for applying glue can be simple and easy to use. For example, the adhesive unit 104 may be attached to the support structure 100 device, as shown above. The user can quickly activate the adhesive unit 104 by pressing a button, trigger, etc. Anyone familiar with the technique, it is clear that the machine can be used for bonding a wide variety of types of devices suitable for gluing.

In accordance with another embodiment of the present invention describe a method for the manufacture of boxes. This method involves the use of the workpiece (e.g. preform 200 shown in Figures 2 and 3), which is a set of adjacent walls and an adhesive tab protruding from one of the walls. Between the walls of the carton blank and the adhesive is applied to the tongue (optional), fold or cut, providing the folding of the workpiece. In general rectangular box shape formed when the adhesive tab and the edge of the first wall and located along the perimeter of the workpiece. The adhesive tab attached to the first wall and forms glued carton blank, with fastening tabs to the first wall includes an insert blank in the first part of the machine for the bonding. The machine for bonding firmly holds the portion of the adhesive tab in place and securely holds the first wall portion in place, so that the edge of the first wall is located near the tongue of the adhesive. Then, at least one of the surfaces - on the adhesive tab or edge of the first wall - glue is applied, and then the tab is folded on the first wall, when between them is already a layer of adhesive.

In one embodiment of this method the blank is set on one side of the machine for the bonding and packing glued extracted from the same side of the machine. With this machine for bonding described herein may occupy a smaller area in comparison with other machines, in which the carton blank mounted on the one hand, and the finished carton is extracted from the other side of the device.

An apparatus for bonding and having various functions, which enhance the degree of comfort when using it. For example, the support structure of the apparatus for bonding may have wheels or rollers. These wheels or rollers allow without difficulty to move the car if needed. Furthermore, the device may be provided with a support plate larger than shown in the drawings. Baseplate larger size can be used for bonding relatively large boxes. In particular, a larger support plate allows it to lay on almost all or all of the preform, which requires less effort from the operator to support the workpiece at the desired orientation in the gluing process. Instead, the base plate bigger, but you can use a separate table, next to the device.

Although the various presented embodiments herein shown design of a machine with workpieces in a horizontal orientation, the device can handle a workpiece mounted in any position. For example, the support structure, the support plate, a device for applying the adhesive and other components can be installed at any angle. Thus, the apparatus for bonding represented in the present invention may have a structure which allows to process the workpiece in a vertical, horizontal or any other orientation. Changeover device for bonding so as to provide a more vertical orientation preform provides a considerable saving of occupied car seats.
