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 blank of corrugated cardboard boxes. 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 faces of the box. Furthermore, on one side of the strip also has to apply the adhesive. The adhesive glue is applied to the device adhesive strip and (or) to the nearest wall and presses the adhesive strip to the nearest wall, this gives a box with four connected parties.

Typical adhesive devices are relatively complex 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 strip. In addition, many devices are adhesive device for applying pressure to the adhesive strip (for example, pneumatic arm) which are intended for connection of the adhesive strip adjacent the wall of the box. Because of the large number of functions and the need for proper synchronization of the various moving parts glue machines are often equipped with computers or other electronic devices for controlling the operation of the various parts of the machine. 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 to which an adhesive. 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 so that the adhesive strip 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 stripes 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.

DETAILED DESCRIPTION OF THE INVENTION

Described herein are embodiments of methods, devices, systems, assemblies and devices forming part of machines for gluing. For example, they are configured so as to provide a simple and effective bonding sites.

In Fig.1-15, and in the following text gives a brief and general description of exemplary devices allowing to carry out the invention. Although the following description is given for gluing packaging machines, it is just one example, while the embodiments of the invention may be implemented with other types of glued objects. Therefore, in the specification and claims, the terms "glue sites", "gum element", "packing materials", "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.

Thus, Figure 1 shows one example of a machine for gluing, which implements some aspects of the present invention. Machine for bonding shown in Figure 1 is only one example of a suitable system / device and does not introduce any limitations in the scope of the functionality of the invention. This system / device can not be interpreted as having a dependence on the specific requirements of any component or combination of components illustrated in the drawing of the system / device or subordinate them.

Referring to Figure 1. Here, the example of construction machines for bonding the support structure 100 shown 102 and the adhesive unit 104 which adheres packaging materials, carton blanks are glued or another object or item presented in a general form callout 106. In particular, the device 100 is composed of a base plate 108 at which the bonding process can move the packaging material 106. The packaging material 106 may be moved along the base plate 108 toward the adhesive device 104 such that device 104 applies glue on the adhesive portion of the packaging material 106. Following application of the adhesive packaging material 106 moves through the rollers 110, which is uniformly applied adhesive on two surfaces of packaging material 106. According to the description, some embodiments may include supply unit driven rollers 110 dm for supplying the packaging material 106 by gluing machine 100. Furthermore, the roller unit 110 Drive may be so designed that allows stacking packaging material 106 after the bonding process. Thus, the roller unit 110 can relieve the operator from performing operations on the movement of the packaging material 106 for bonding machine 100. After the packing material was glued and 106 (optional) is composed in a stack, in a similar manner to the gluing machine 100 can produce the following adhesion wrapping material 106.

2A and 2B show one example of adherend object 106 which represents the carton blank of corrugated paperboard 106. The workpiece 106 has four walls, designated by the letters A, B, C and D, and the adhesive strip T. The walls A and B are separated longitudinal folding lines or notches 112 and slots 114. Similarly, the wall B, and C are separated by longitudinal folding lines or notches 116 and slots 118, and the walls C and D are separated by longitudinal folding lines or notches 120 and slots 122. In the illustrated embodiment, the adhesive strip T stands only along a portion of the width of the wall and D is separated from the wall of the longitudinal fold line D or notch 124. However, it should be appreciated that the strip T can act along the entire width of the wall and D can be separated from the wall by a fold line D, or notch 124 or slot .

The walls A, B, C and D further have transverse notches or fold lines 126, 128, 130 and 132, respectively, which together with the slots 114, 118 and 122 define oppositely disposed flaps which are folded to form the lid and bottom of the box. Longitudinal and transverse fold lines, the slits and adhesive strip T can be performed using a cutting machine, Creaser and (or) using a stamping press.

After the preform 106 formed fold lines and slits, the blank 106 can be folded along these crease lines so that the box begins to form. An example is shown in Figure 2. Here, the preform 106 V. first folded in half along a fold line 116. When folded along the fold lines 116 A and walls are walls of D and C, respectively. The adhesive strip T can then be folded along fold line 124 and is connected to the wall A, in accordance with the teachings herein. Based on the reasons described above, it should be noted that the blank 106 is folded as shown in Figure 2B, the adhesive strip T is disposed at the edge of the workpiece 106, not in the center of the workpiece 106. It should also be noted that the adhesive strip T is disposed A wall outside and not inside of the wall.

As shown above, a plurality of adhesive machines are designed to allow the cardboard to fold the carton blank so that adhesive strip is located in the middle of the workpiece that requires a large frame which is able to reach the central portion of the carton blank and apply glue on the adhesive strip. Glutinous machine provided in the present invention is adapted for gluing the carton blank so that when the adhesive strip is bent at the edge of the workpiece (as shown in Figure 2B). Thus, the machine for bonding provided by the present invention eliminates the need for a large frame for applying adhesive on the adhesive strip. To be more precise to say that the glue machine, provided in the present invention is able to apply the adhesive on the blank boxes of any size without the need to setup, while keeping unchanged compact size. This makes it possible to install such a machine for bonding in close proximity to other machines for the production of boxes, such as die cutting machines, machines for making slits and the fold lines and lifts primer machines. Thus, the machine for bonding provided by the present invention, not only takes up less space in a factory or warehouse, but also reduces the time required for the production of the box thanks to its location in close proximity to other machines, since it reduces the time it takes to the operator has moved from one machine to another in the processing of the carton blank.

Referring to Figure 3, which shows a perspective view of a bonding machine 100 according to one embodiment of the present invention. As seen in Figure 3, the bonding machine 100 includes a support structure 102, which are attached to all other components of the machine 100. In this example, it is seen that the support structure 102 includes support frame 134 and a rack 136 which is fastened to the support frame 134 . Additionally, the supporting frame 134 can stop the wheels or rollers 138, 100 to facilitate moving the machine from one location to another. The wheels or rollers 138 can be equipped with brakes or other devices to prevent accidental movement of the wheels or rollers 138.

As shown above, the support structure 102 is provided with various components for the gluing machine 100, which are attached thereto in various ways. One such component that is attached to the top of the rack 136, a base plate assembly 138. The base plate assembly 138 consists of a support plate 108 which is adapted to support the carton blank 106 while it (blank 106) is moved through the machine for bonding 100. The base plate 108 can be adjusted in size so as to provide the work 106 with workpieces of different sizes, or fragments thereof. For example, base plate 108 may be configured so that only the edge of the workpiece support 106, or the entire preform 106. Thus, the support plate 108 can have virtually any size necessary for supporting workpieces 106. On the other hand, the baseplate 108 may located next to the table, stand, shelf or the like, which can be used as auxiliary tools to support the workpiece 106. For example, Figure 6 shows a table located very close to the edge of the base plate 108 so that the base plate 108 or the operator does not support the workpiece 106 in its entirety. Increasing the size of the base plate 108 or setting the table next to the base plate 108 may be practical when bonding large pieces 106 using 100 machines.

The base plate 138 also includes a guide rail 140 that provides proper positioning of the workpiece 106 on the base plate 108 so that the glue could be applied to the desired portion of the workpiece 106. As seen in the example shown in Figures 3 and 4, the guide rail 140, and support plate 108 together form a trough 141 that extends at least partially beyond the length of the base plate 138. The chute 141 is opened from the support plate 108 and has a size such that it came edge folded blank 106 located thereon. Moreover, trough 141 is shaped to properly orient the preform 106 and combine with a device for applying an adhesive 142, more details of which will be given below. In particular, in the construction example shown in detail, that the groove 141 comprises a horizontal base plate 108, a vertical wall 144 and the upper inclined plate 146.

After the blank 106 is folded as shown in Figure 2B, a part of the workpiece 106 with the adhesive strip T is mounted on the base plate 108 so that at least a portion of the preform 106 was in the trench 141 (see. 5A). Thus, the fold line 124 between the wall D and strip T gets in front of the vertical wall 144 and strip T is maintained in a partially flexed at an angle θ upper plate 146. Setting the fold line 124 against the vertical wall 144 allows the operator to quickly, easily and accurately set the workpiece 106 and move the workpiece through the machine 106 for bonding 100. Specifically, the operator can move the workpiece 106 through the machine 100 for bonding to the desired position, maintaining the preform 106 so that fold line 124 located opposite the vertical wall 144.

As described above, the upper plate 146 supports the strip T at an angle θ, which enables the device for applying the adhesive 142 applied adhesive between the strip T and the wall A, and allows to compress together the strip T and wall After applying the adhesive between them, without damaging the strip T . Thus, the operator can quickly, easily and accurately position the workpiece 106 on the base plate 108, without visually checking the position of the workpiece 106. As described above, support plate 108 may have a shape other than flat, as shown in Figures 1 and 3 -6. For example, base plate 108 may have one or more rollers, conveyor belts and similar devices. On the other hand, other embodiments for bonding machines 100 have the base plate 108. In such embodiments, other components of the machine 100 and (or) an operator or a separate structure (e.g., table) may provide support to the workpiece 106 as it moves through the machine for bonding 100.

Those familiar with the art, it is clear that the guide rail 140 may have a very different shape without departing from the subject of the present invention. As will be shown below, the guide rail 140, for example, may be a plurality of rollers mounted so as to properly orient the workpiece 106 as it moves through the machine 100 for bonding.

As shown above, the base plate assembly 138 has a device for applying the adhesive 142 attached thereto. Apparatus for applying adhesive 142 is connected to the adhesive supply system 148 (see Fig. 3), which will be described below. Apparatus for applying adhesive 142 includes an adhesive dispensing nozzle 150 disposed near the guide rail 140 and the base plate 108. In the shown construction example of the dispensing nozzle the adhesive 150 is sufficiently far away from the base plate 108 so that the walls A and D of the carton blank 106 could be moved along the supporting plate 108 and a dispensing nozzle for the adhesive 150. In addition, a glue nozzle 150 has such a shape, direction and type (see FIG. 4 and 5) to apply the adhesive to the desired location. For example, in the illustrated embodiment, the dispensing nozzle 150 is configured so as to enter the space between the walls A and B of the adhesive strip T workpiece 106 until strip T is folded over the wall part A.

Shown above construction adhesive dispensing nozzle 150 provides for applying glue to desired items workpiece 106. For example, as shown in Figure 5 when the carton blank 106 is moved along the base plate unit 108 to the adhesive 104, the dispensing nozzle 150 the adhesive is able partially to enter under the adhesive strip T. While the dispensing nozzle 150 the adhesive strip T is under, the adhesive is applied to the strip and T (or) near the edge of the wall A. In other embodiments, the dispensing nozzle the adhesive 150 can not go under the strip T, but the however, is capable to apply the adhesive between the adhesive strip T and wall A. In both cases, the adhesive may be applied between the adhesive strip T and A wall, providing a bonding these parts together.

Despite the fact that the dispensing nozzle for the adhesive 150 is shown so that it is directed generally toward the guide rail 140, and is capable of connecting the adhesive strip T and the outer part of the wall A, it should be borne in mind that the dispensing nozzle for the adhesive 150 can be oriented and in other directions. For example, the dispensing nozzle the adhesive 150 may be directed in the opposite direction so as to enter the space between the adhesive strip and the wall T A T if the strip is adhered to the inner wall portion A. In addition, the dispensing nozzle the adhesive 150 may be attached to a base plate assembly 138 with the possibility of adjusting its position so that the dispensing nozzle for the adhesive strip 150 is glued or T with the outer or the inner side wall or A will operate with the carton blanks 106 of greater or lesser thickness,

Management gluing using glue dispensing nozzle 150 can be different variants of mechanical devices. For example, after the carton blank 106 are arranged so that the dispensing nozzle for the adhesive 150 located next to the strip T, the operator of the machine for bonding 100 may include an adhesive supply nozzle 150 with the help of the buttons, switches, pedals, etc. (not shown) to begin applying the adhesive to the workpiece 106. After the application of the necessary amount of adhesive to the strip T and (or) the wall A, the operator can shut down the dispensing nozzle for the glue 150, using the same or a different management body (button switch , pedal, etc.).

Alternatively, the bonding machine 100 may be provided with an automatic detection system preform 106 which includes supplying the adhesive to the strip and T (or) on the wall A. Such automated system may also determine the sufficient amount of adhesive applied to the strip and T (or) A wall or outlet strips and (or) the workpiece 106 from the dispensing nozzles for the adhesive 150. In each case, the automated system will disconnect the dispensing nozzle for the adhesive 150 and stop the flow of glue from it.

For example, according to an embodiment of the present invention shown in Figures 4 and 5, this automatic system is provided with one or more sensors 152 for detecting the workpiece 106 and (or) of the adhesive strip T. One or more sensors 152 can be mounted on the rack 136, a guide rail 140, the baseplate 108, or to glue the unit 104 so that the sensor 152 can record the presence or the approach of the workpiece 106 and (or) the strip T and activate the dispensing nozzle for the glue 150 at the moment when it is placed between the strip T and wall 152 A. Examples of sensors that can be used for this purpose include (among others), infrared sensors, laser sensors, photodetectors, contactless proximity sensors, cameras, ultrasonic sensors, sound sensors, sonar, radar, or any combination thereof.

As described above, the base plate 138 includes a roller 110. In the embodiment of the present invention shown in Figures 1 and 3-5V, roller unit 110 includes two rollers 154 and 156, located near the dispensing nozzle, in generally one above the other. Rollers 154 and 156 rotate in the same vertical plane, but in opposite directions so as to move the carton blank through the machine 106. The roller 154 rotates clockwise and the roller 156 - counterclockwise. The roller 156 is disposed so that its outer circumference is approximately at the same level or slightly higher than the base plate 108. The roller 154 is located sufficiently above the roller 156, so that the workpiece 106 can be moved between the rollers 154 and 156. As preform 106 is moved along the support plate 108 behind a glue dispensing nozzle 150, a part of the preform 106 on which the adhesive strip T, the adjacent edges of the wall and A and D are held between the rollers 154 and 156. Rollers 154 and 156 are driven home so as to press the strip T wall and A and D together when the adhesive is located therebetween, wherein the adhesive strip T is attached to the wall of A.

Furthermore, in some embodiments, the invention provides a fixing rollers 154 and 156 to the motor 158, which allows the rollers 154 and 156 move the workpiece 106 along the base plate 108. In addition, a motorized roller unit 110 may be designed to provide 106 after stacking blanks gluing them in accordance with the present invention.

As seen from Figure 1, 3 and 5B, the roller unit 110 may also include one or more rollers 159 that rotate in a horizontal plane. In the illustrated embodiment, the roller 159 mounted in the same vertical plane between the rollers 154 and 156 and the trough 141. The roller 159 is also mounted so that it contacts the fold line 124 as the workpiece 106 move behind the dispensing nozzles for the glue 150. This configuration Roller 159 further ensures the proper positioning and movement of the workpiece 106 during its processing in the machine 100 for bonding.

As seen in Figure 5B, roller unit 110 may be installed with respect to the dispensing nozzle for the adhesive 150 so that the front edge of the workpiece 106 and (or) of the adhesive strip includes a roller unit 11 0, while the dispensing nozzle 150 has glue applied glue the remainder of the strip and T (or) of the wall A. For example, pulley 110 may be placed at a distance of approximately 2 to 6 inches from the dispensing nozzle for the adhesive 150. One embodiment of the invention provides for the distance between the dispensing nozzle 150 and the adhesive roller unit 110, equal to about 4 inches. As shown above, the roller unit 110 may have a plurality of rollers, which are located between the dispensing nozzle for the adhesive 150.

Moving the finished workpiece 106 after the dispensing nozzles for the glue 150 in roller unit 110 may be provided by an adhesive strip T orientation with respect to the wall A, when the adhesive between the strip and the wall of the T A has already been done. As shown above (see. 5), the strip T can be folded so that the strip T and A wall, after applying the adhesive between them, to form an angle θ. Proper selection of the angle θ can quickly press the adhesive strip T to the wall of the block A by rollers 110, without damaging the strip T. In particular, as shown in Figure 5B, since the angle θ between the strip and the wall of A T after application of adhesive therebetween is relatively small , the clamp front wall strips T to A roller unit 110 until the end portion of the workpiece 106 between the strip and the wall T A still applied glue does not cause an undesirable deformation, bending or damage of the strip T. Thus, the roller unit 110 may press the front T portion of the strip to the wall A, while the rear portion of the adhesive strip T forms an angle θ, and the adhesive may be applied to the back of the workpiece 106 without damaging the adhesive strip T. Some embodiments of the present invention contemplate that the angle θ is between 10 to 20 ° °. Similarly, in other embodiments, the angle θ is approximately 15 °.

Referring now to Figures 7-11, which illustrate alternative embodiments of the unit of rollers, which can be installed in the machine for the bonding rolls 100. Block 160 shown in Figures 7-11, may be mounted on the base plate 138 so as to perform the functions of support plate 108, guide rail 140 and the roller block 110. In other words, the roller unit 110 and a support plate 108 (partially or completely) with the guide rail unit 140 may replace the rollers 160.

In the illustrated embodiment, the roller unit 160 is composed of a plurality of lower track rollers 162 and a plurality of side rollers 164, 106 supporting the workpiece and providing the alignment and movement of the workpiece 106 within the bonding machine 100. Thus, a plurality of lower track rollers 162 are configured such that at least a portion of the workpiece 106 rests on them while the workpiece 106 is moved in the machine 100. Thus, the lower supporting rollers 162 may operate as a base plate 108, and (or) be used instead. Thus the lower supporting rollers 162 can be regarded as the base plate. Thus, in some embodiments, a composition for the bonding machine 100 flat base plate 108 is not included.

In addition, several of the lower supporting rollers 162 allow the carton blank moving through the machine 100 with minimal resistance. A plurality of side clips 164 are the same as described above for the vertical wall 144. Thus, the side rollers 164 permit properly align the carton blank 106 as it moves through the machine 100 for bonding.

For example, setting the fold line 124 against the side 106 of the workpiece roller 164, the operator can quickly, simply and accurately set the workpiece 106 and the workpiece 106 move through the apparatus for applying adhesive 106. To describe it more in detail, then, setting the folding line 124 opposite the workpiece 106 a plurality of side clips 164 and moving it thereon, the operator can be sure that the preform 106 has leveled properly with respect to the dispensing nozzle for the adhesive 150. As with the lower support rollers 162, the side rollers 164 create minimum resistance when moving the workpiece 106 100 through the machine.

Roller unit 160 is also composed of several upper rollers 166, 168, 170, 172 and 174. The upper rollers 166, 168, 170, 172 and 174 are positioned vertically over a plurality of lower track rollers 162 and rotate generally in the same vertical plane that the support rollers 162. In contrast to the 110 block of rollers roller unit 160 has rollers mounted in front (left) and after (left) dispensing nozzle 150. The glue rollers mounted upon the adhesive dispensing nozzle 150, perform the same functions, and that the rollers 154 and 156, the description of which is given above. Thus, the rollers 172 and 174 and the lower supporting rollers 162 mounted underneath are intended for pressing the adhesive strip T to the wall After applying adhesive between them.

Rollers mounted to the dispensing nozzle the adhesive 150, and in particular, the upper rollers 166, 168, 170 may operate in the same way as the guide rail 140 and in a special way curved upper plate 146, the description of which is given above. Thus, the rollers 166, 168 and 170 of the adhesive strip T is held against the wall of A so as to form an acute angle. As previously shown, the retention strip T at an acute angle relative to the wall and moving the carton blank 106 Vehicle 100 provides numerous advantages. For example, if the rollers 166, 168 and 170 hold the strip T against the wall but at an acute angle to the dispensing nozzle the adhesive 150 may be applied between the adhesive strip T and the wall and moving the workpiece 106 along the machine 100. Furthermore, while distributing glue nozzle 150 continues to apply the adhesive between the strip and the wall of T A, the front portion of the strip T can be pressed against the wall and the rollers 172 and 174 without creating undesirable mechanical stress and causing bending or damaging the strip T. Thus, the rollers 166, 168 and 170 may be fully or partially perform the function of the guide rail 140 with the inclined plate 146 and the rollers 166, 168 and 170 may be completely or partially form the guide rail.

In the illustrated embodiment, the upper rollers 166, 168 and 170 are installed at different heights relative to each other. Thus, the roller 170 mounted vertically below roller 168, which is mounted vertically below than roller 166. This arrangement creates a narrowing channel through which the preform 106 has to pass to the strip T. Thus, during the passage of the edge of the wall with D adjacent fold line 124 above the lower supporting rollers 162 in the direction of the dispensing nozzles for the upper roller 150 of glue 166, 168 and 170 capture the adhesive strip T and gradually presses it against the wall of A. Upper rollers 166, 168 and 170 are inclined and shaped so that the strip T is set above the nozzle 150 by passing the strip T at the nozzle 150. The construction of the upper rollers 166, 168 and 170, gradually setting strip T in position, shown in Figures 8 and 9.

In addition to proper positioning of the adhesive strip T, the upper rollers 166, 168 and 170 are also inclined in such a manner that they establish strip T so that the rollers 172 and 174 pressed strip T to the wall A, without causing a break, bend or excessive compression, which could to compromise the integrity of the strip T. As seen from Figures 10 and 11, after the strip T has passed through the nozzle 150, the strip comes into contact with the upper roller 172. The upper roller 172 mounted vertically below the roller 170. This position of the roller 172 provides a clamp strip T to the wall A between the upper roller 172 and a lower roller 162. Note that the vertical displacement of the adhesive strip T due to the lower position of the lower roller 172 is minimal. Thus, as the dispensing nozzle the adhesive 150 continues to apply the adhesive between the strip and the wall of T A, the upper roller 172 can press the front part of the strip panel A to T, without causing deformation, cracking, or other damage.

After passing under the upper roller 172 bar T can pass between the upper roller 174 and lower roller 162. The other upper roller installation 174 may increase the clamping strip T, thereby providing sufficient time for curing the adhesive applied between the strip and the wall T A.

Similarly, block rollers 110, described with reference to Figures 1 and 3-6, block rollers rollers 160 can be activated manually or can be equipped with motor-driven.

For example, the rollers can freely rotate and begin to rotate when the carton blank 106 reach each roller. Another embodiment provides for the installation of one or a plurality of motors (not shown), which will create an automatic feeding system.

Returning to Figures 1 and 3-6. The dispensing nozzle 150 for the adhesive application device adhesive 142 is attached to the adhesive supply system 148. In the illustrated embodiment, the feed system includes a glue reservoir with glue (not shown). This tank has a connection with the glue with glue dispensing nozzle 150 through the hose 176, on which the glue is fed from a reservoir to the nozzle 150. A hose 176 can have any form suitable for feeding adhesive (instead of the hose, among other things, can be used, and so the tube. P.). Apparatus for applying adhesive 142 is also provided with a pump for pumping the adhesive from the reservoir into the dispensing nozzle for the adhesive 150. In this embodiment, the pump is built into the feeding system 148. Other embodiments of the adhesive may include a separate pump arrangement and delivery system 148 Adhesive.

Gluing machine 100 may use different types of adhesive. For example, if using hot glue, for instance a thermoplastic adhesive, with the adhesive reservoir may include a heater (not shown) for melting the adhesive. The expanded adhesive may then be applied to the adhesive dispensing nozzle 150 through the hose 176. The bonding machine 100 may be used and other types suitable for the application of glue: Adhesive for cold gluing resin, polymer adhesives, elastomers, pressure sensitive adhesive (e.g. neoprene) or adhesive curable under pressure.

Despite the fact that the device for applying the adhesive 142 shown in this embodiment is provided with a dispensing nozzle for the adhesive 150, through a hose 176 connected to a reservoir for the glue, in car 100 can use various types of devices for applying the adhesive. For example, a device for applying the adhesive 142 may include a rechargeable cartridge glue sticks and embedded heating element for melting the adhesive prior to its application. 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, it can be mounted on the supporting structure of the device as described herein. The user can quickly activate the device for applying the adhesive by pressing a button, trigger, etc. Anyone familiar with the art will appreciate that the machine can be used for bonding a wide variety of types of devices suitable for gluing.

Gluing machine 100 may have a variety of features that improve the level of convenience when working with it. So, presented version of the machine for bonding 100 may include zagibatel (not shown) similar zagibatelyu described in this document. For example, this zagibatel may be secured to the support structure 102 and turn down adhesive strip T workpiece 106 to the position shown in Figure 2 B. Thus, the base plate portion 108 opposite the roller unit 110 and a device for applying the adhesive 142 may extend further beyond zagibatel rail 140. This can be coupled to this part of the baseplate 108. The carton blank 106 may be mounted at this end of the base plate 108 so that the strip T is positioned over zagibatelem. Zagibatel can rotate and bend the strip T towards the wall A. Moreover, zagibatel may be designed to only rotate through a certain angle to bend the strip at a certain angle θ, as described above.

Although the shown embodiment having a generally stationary frame, the baseplate and the adhesive application device and it is necessary to move the carton blank with respect to the support frame for the bonding, other configurations are possible within the framework of the present invention. For example, a machine for bonding provided by the present invention may be constructed so that the machine can move relative to the workpiece in order to glue on it and pressing surfaces are coated with adhesive to one another. If we consider an embodiment in which the blank for the box may be held stationary, either the machine operator or forces, the bonding machine itself can be moved forward and backward relative to the workpiece. When moving the machine for bonding in one direction or the guide rollers are moved over the rails of the adhesive strips and set it as described above. The dispensing nozzle for the adhesive can be moved between the strip and the wall of the T A and the rollers will compress the two surfaces together.

Referring to 12-15, there is shown a machine 200 for bonding, in accordance with one embodiment of the present invention. In general, in accordance with this embodiment, the machine 200 includes a support structure 202 and the adhesive applicator 204, providing bonding packaging materials such as a blank for the box 106. The supporting structure 202 consists of two uprights 206 and cross member 208 mounted and fixed between the uprights 206. Between the uprights 206 also mounted and fixed base plate 210. The base plate 210 is intended for supporting the packaging material (carton blank 106) and fixing it in place in the process of applying an adhesive application device using the adhesive 204. In addition, hinged to the base plate 210 (or, alternatively, to the support structure 202) is mounted zagibatel 212 which bends the portion of the packaging material 106.

As seen from Figure 12, the support plate 210 is vertically mounted under the cross member 208 so that the base plate 210, the cross member 208 and strut 206 define a rectangular opening in the machine for applying adhesive 200. The carton blank 106 may be completely or partially inserted into a hole formed the reference plate 210, cross member 208 and struts 206. After insertion into this hole preform 106 supported on the base plate, as shown in Figure 12. If the workpiece 106 is mounted on the base plate 210, 214 drops sticking to the workpiece 106 and holds it in position on the base plate 210, as shown in Figure 13.

Gluing machine 200 also may have one or more guide rails 216 and one or more detents 218, allowing proper positioning of the carton blank 106 on the base plate 210. For example, prior to securing in place preform 106 tack 214, the operator can arrange one end of the workpiece 106 flush with the guide rail 216, and the edge strip T - very close to the one or more stoppers 218 as shown in Figure 12. Guide rail 218 and the detents 218 allow the operator to properly set the workpiece 106 on the base plate 210 so that the device for applying the adhesive 204 caused the adhesive to the desired portion of the workpiece 106 and 212 zagibatel bent to the desired part of the workpiece 106.

In the illustrated embodiment, the guide rail 216 is a post that is attached to the base plate 210. The geometric shape shown in the drawing the guide rail 216 allows the operator quickly to position and orient the carton blank 106 abutting the guide rail 216, relying on the sense rather than a visual orientation at the correct location in the workpiece 106. Similarly, the stoppers 218 are physical barriers to orientate the workpiece 106. In the illustrated embodiment, stoppers 218 are attached to zagibatelyu 212. Stops 218 prevent too deep insertion of the carton blank 106 into the opening formed by the base plate 210, the cross member 208 and struts 206. Stoppers 218 allows the operator to quickly align and position the workpiece 106 with respect to the stopper 218, focusing on feeling rather than a visual inspection, and provide the proper positioning of the workpiece 106.

Thus, the operator can insert a blank box in the hole and rapidly place it in relation to the guide rail 216 and the stopper 218 so that the preform 106 will be ready for gluing and folding at the right place. However it is clear that the guide rail 216 and the stoppers 218 may also have another shape. For example, the guide rail 216 and the stoppers 218 may be a visual indicator, in the form of lines that indicate a place positioning the workpiece 106. Alternatively, the guide rail 216 and the stoppers 218 may have sensors and (or) the warning means, such as lights, sound signals and the like for applying a signal to the operator as to where and how to locate the carton blank 106 on the base plate 210.

After the carton blank 106 is properly positioned on the base plate 210, 214 can drop sticking to the workpiece 106 to securely hold it in place. As shown in Figures 12 and 13, taking 214 is attached to the support structure 202 so that it is above the base plate 210. More words, sticking 214 has a movable connection with the cross member 208 by means of one or more movable joints 220 and spring 222 so 214 sticking that can selectively move between an upper position (see. Figure 12) and a lower position (see. Figure 13). Clamp 214 can save the current position. For example, 214 may be stuck in the upper position until the operator manually lowers sticking 214. Similarly, 214 may be stuck in the lower position, until the operator will not lift it manually. When this sticking 214 will not spontaneously descend or ascend without operator intervention, for example in the gluing process.

Clamp 214 may have a lever 224, which allows the operator to easily move the 214 stuck to the desired position. For example, after the workpiece 106 is properly positioned on the base plate 210 for bonding, the operator can press the lever (224 pull or rotate) so that sticking 224 goes to the workpiece 106, as shown in Figure 13. In the lower position stuck 214 may interact with the support plate so as to securely hold the workpiece 106 in place during bonding.

Clamp 214 can be lowered for a certain distance, thereby providing the necessary clearance for the workpiece 106 between tack 214 and the base plate 210 so that the sticking 214 does not damage the workpiece 106. In some embodiments, stuck 214 may be omitted as long as there is no fixed some effort. Thus, taking 214 can automatically adjust to the workpiece 106 different thicknesses.

After the carton blank 106 is secured in position on the base plate 210, as shown in Figure 13, the adhesive applicator 204 may be used for applying the adhesive portion of the preform 106. In the illustrated embodiment, the device for applying the adhesive 204 is a device ZM Scotch Weld Hot Melt. Adhesive application apparatus 204 is attached to the cross member 208 so that it can move back and forth over the workpiece 106. The adhesive applicator 204 may be activated as already described above. For example, the operator may activate the device for applying the adhesive 204 by pressing the button 226 or the trigger lever moving and the like Similarly, the adhesive application device 204 can be equipped with an automatic activation system, in accordance with the above description. For example, the adhesive applicator 204 may have one or more sensors (not shown) which detect when the dispensing nozzle 228 the adhesive 204 is positioned over the workpiece 106. If set so, the adhesive applicator 204 may apply adhesive to workpiece 206. Thus, the operator can move the adhesive applicator 204 so that the dispensing nozzle 228 the adhesive is above the workpiece 106, and to manually activate the device 204, or provide an automatic activation of the adhesive application device 204, and to apply the adhesive to the desired surface (s) of the blank 106. It is understood that when the applicator is moved over the glue 204 and the workpiece 106 is activated, the adhesive may be applied to one or more surfaces of the workpiece 106. For example, the dispensing nozzle the adhesive 228 may apply adhesive to the adhesive strip T, near the edge of the wall A or on both these surfaces.

In conjunction with the adhesive application device 204 support structure 202 also may have a movement system of cables and hoses 230 mounted thereon. System moving cables and hoses 230, such as energy management chain guide KabelSchlepp, can be used for flexible connection of power lines (electric wires and hoses with compressed air) to the device 204. The glue application system moving cables and hoses 230 is a safe design eliminates the possibility of damage to the cables, hoses and ensuring its free movement in conjunction with the adhesive application device 204.

As seen from Figures 12 and 13, when the blank 106 is secured in position on the base plate 210, with adhesive strip T is over zagibatelya 212 D wall (not shown) is located directly on the base plate 210, located on the A side wall of D, and the fold line 124 between the strip and the wall of A T located above the hinge area between the baseplate 210 and zagibatelem 212. Thus, after the adhesive is applied to the strip and T (or) to the wall A, zagibatel 212 can rotate and bend the strip T at A wall as shown in Figure 14. Thus after applying the adhesive to the workpiece 106 zagibatel 212 may be swiveled 232 upwardly from the position shown in Figures 12 and 13, in the position shown in Figures 14 and 15. Rotation zagibatelya strip 212 bends upward about the fold line T at 124 A. Zagibatel wall 212 can also be used for pressure on the adhesive strip T in the distribution of the glue on the wall of the strip A and T. For zagibatel 212 can press and hold the top position, ensuring proper bonding strip T and A wall using adhesive applied between them .

It should be noted that the stops 218 which are attached to zagibatelyu 212, able to penetrate into zagibatel 212 when it is rotated in accordance with the above description. Thus, in one embodiment of the present invention, the stoppers 218 are provided with springs connected to zagibatelem 212 and located inside it. Thus, when pressure is applied to the ends of the stoppers 218 may include detents in zagibatel 212. Here, when zagibatel 212 rotates upward and the stoppers 218 abut against the wall surface A, they are retracted inside zagibatelya 212 without damaging the wall. When zagibatel 212 turn down, moving away from the workpiece 106, the stoppers 218 will be withdrawn back out of the zagibatelya 212 under the embedded springs (not shown).

After the adhesive strip is attached to the panel A, zagibatel 212 may turn back to the initial position as shown in Figure 12, and stuck 214 rises above the workpiece 106, thereby allowing free removal of the workpiece 106 for bonding machine 200. After that glued carton blank 106 can be derived from the machine, stacked and sent to the warehouse for later use.

As illustrated, in particular from Figure 15, this embodiment for bonding machine 200 has a sufficiently compact form. This provides an advantage for the machine 200, when used in the complex machines for the production of packaging, or by using it on an occasional basis and then stored in a warehouse. For example, the small size allows to install 200 machines this machine among other machines, without removing them too far from one another. Similarly, when the vehicle 200 is not used, it can move up to the wall where it will be stored without taking up a lot of valuable space on the production floor.

200 gluing machine can be used independently or with a table / counter, which allows to increase the working surface of the machine 200. 12-15 shows a machine 200 placed next to the table, providing additional support for the workpiece 106 in the process of bonding. Alternatively, the machine 200 may be equipped with a larger support structure 202 and (or) of the support plate 210.

Bonding machine 200 may also be adapted so as to simultaneously glued one or more workpieces 106. As described above, the machine for the bonding adhesive 200 is placed to a workpiece 106. Alternatively, the machine 200 can place and secure multiple workpieces sticking 214 106 near. Thereafter, the adhesive may be applied to each preform 106, and zagibatel 212 may be used for the simultaneous flanging of each adhesive strip T at several workpieces 106. In addition, several box blanks 106 may be stacked on the base plate 210 alone, or the workpiece 106 may be assembled in single blank that may be placed on the base plate 210. In case of assembling multiple pieces 106 must remain possible their separation after the bonding process. Thus, several box blanks 106 may be glued in a single sequence of operations that can increase the number of boxes produced per time period.

One advantage of the invention is the fact that it is possible to perform bonding workpieces of different sizes, without changing the configuration or the settings of the machine for the bonding. For example, the bonding machine 100 may be used for bonding the strip is very large, by simply moving the workpiece edge folded blank from the adhesive strip through the guide rails 140 under the dispensing nozzle for the adhesive 150 and through the roller unit 110, as described above. After the machine 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 machine 100 to operate with workpieces of different size. The same applies to the bonding machine 200. Thus, in using the machine 200 may be held in place, glue and bend the workpiece in one size, and thereafter can immediately glued blank of a different size, without having to adjust any components of the machine 200. In this , the machine for the bonding, which is the subject of the present invention allows, in accordance with needs, glued blank of arbitrary size directly one after another without any downtime associated with the migration of the machine.

This feature of the invention distinguishes it from most standard devices for bonding, which require special settings for specific sizes of box blanks. More words, most of the machines are configured for gluing pieces of processing batches of the same size. 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 other workpieces, such as dimensions of 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, glue machine provided in the present invention is able to apply the adhesive to the blank boxes of any size, in any order, without the need for any re-tuning.

Although the various presented embodiments herein machines shown in connection with the type of workpieces 106 in a horizontal orientation, this machine 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 machine for bonding provided by the present invention may have a structure which allows to process the workpiece in a vertical, horizontal or any other orientation. Thus, resetting the machine for bonding with greater vertical orientation allows the workpiece to obtain significant savings in space occupied by the machine.

Machines for bonding shown in the present invention also have particular advantages in the treatment of billets supplied from a permanent source of the packaging material (corrugated paperboard) folded "concertina". It is understood that when feeding from a permanent source, for example, in 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 in the center of one of the walls or an adhesive strip. Such fold lines "accordion" can lead to the fact that the blank will not lie flat and the walls and the adhesive strip will not be aligned sufficiently being applied. In this case, the operator must hold the wall and the adhesive strip in place by gluing strips.

Adhesive machines presented in the present invention reduces the disadvantages associated with such fold lines. Because the machine for bonding provided by the present invention causes the glue and attaches the adhesive strip when it is located on the edge of the carton blank, the only case where the fold line "accordion" presents difficulties it is when this line goes to the center of adhesive strips. However, the probability of such an arrangement the fold line is extremely low. Furthermore, guide rails, roller blocks, clamps and zagibateli described above, also reduce the inconvenience associated with fold lines "accordion". For example, zagibatel 212 may exert sufficient pressure on the adhesive strip during its bending of the wall A to smooth any fold line. Similarly, the pressure applied to the adhesive strip roller unit described above may also smooth out any wrinkles that may be present on the strip.

Thus, machines for bonding provided by the present invention provides a quick and convenient method of gluing pieces of boxes of virtually any size, without requiring reconfiguration or changeover to different sizes of workpieces, thereby reducing or eliminating the potential difficulties associated with the use of packaging materials composed " an accordion.
