Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pair case manufacturing apparatus that attaches two pair case packaging boxes having connecting margins to form one package.

BACKGROUND ART Conventionally, two or more packaging boxes made of cardboard or other cardboard containing products have been combined into one package. This means reducing the types of packaging boxes and standardizing their sizes, storing the minimum number of products necessary to handle them in one packaging box, and reducing the size of the box when a large amount of products are required. The number of boxes can be increased without changing the number of boxes, and these packaging boxes can be packed into one package for convenient handling such as storage and transportation.

However, these packaging boxes have conventionally been assembled using adhesive tape or bands, or by storing them in exteriors such as cases or outer boxes, but all of these methods require extra effort and packaging materials, and the band In the case of hanging, there is a risk that the product may be damaged due to the band digging into it, and in the case of tape, it has various disadvantages, such as peeling off and spoiling the aesthetic appearance.

Therefore, the inventors of the present invention have developed a packaging box body, in particular, a container and a lid part that are integrally formed, and a packaging box body made of thick paper such as corrugated paper (A type and B type in JIS). We have developed packaging boxes for various paired cases in which two or more packaging boxes are connected by protruding one or several connecting margins.

By the way, these boxes were originally made as a single independent box, so in order to achieve the intended purpose, it is necessary to store them in the product storage area after manufacturing the box. It is necessary to connect the boxes.

Among the above-mentioned packaging boxes for pair cases, the present invention is directed to a cardboard packaging box (particularly A-type) in which the tab surfaces 1 and 1' and the side surfaces 2 and 2' are configured in series as shown in FIG. When two cardboard packaging boxes are placed facing each other, the side edges of the other tab surface 1' or side surface 2' of the opposite To provide a device that continuously, automatically and reliably connects two packaging boxes A for pair cases each having a protruding connection margin 3 to be pasted to form one package.

Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

Figures 2 to 4 show an example of the device of the present invention, which is placed behind a box manufacturing line or a line for storing products in boxes, and is used for pair case packaging boxes A (hereinafter referred to as "packaging boxes"). 3.
A glue applicator 4 that applies glue to the inner surface of the packaging box A, a direction changing device 5 that alternately rotates the packaging boxes A by 90 degrees in the opposite direction, and a packaging box A that faces each other two by two. It consists of a crimping device 6 that brings A into close contact and crimps it.

The glue applicator 4 consists of a fast-feeding belt 7, a glue roller, and a conveyor table 9 that moves up and down. The fast feed belt 7 is the feed belt 10 at the tip of the storage line.
The packaging boxes A, which are stretched adjacent to and at the same level as the feed belt, are sent out one after another from a storage device (not shown) and placed on the feed belt 10 are placed on the feed belt 10 by the stopper 11 and the detection limit switch 1.

transport upwards. The conveyor stand 9 includes roller conveyors 91 arranged in a row approximately the length of the packaging box A and roller conveyors 91 having a small diameter and shorter than the width of the packaging box.
The roller conveyor 91 is stopped at the same or slightly lower level than the fast-feeding belt 7.

The packaging box body A sent from the fast-feeding belt 7 is positioned on the roller conveyor 91 and transferred to the conveyor table 9.
When the limit switch 13 at the upper end of the vertical guide plate 12 provided at the rear is pushed, the conveyor table 9 descends, and along the way, the glue application roller 8 as a coating device applies the glue to the inside of the connecting margin 3 of the packaging box body A. . In the figure, 8' is a guide roller for gluing. Also rod 9
The vertical movement of 2 is performed by a cam, a geared motor, etc. Next, the packaging box body A is transferred to the driving conveyor 14.
The signal is sent to the direction changing device 5 by.

The direction change device 5 includes a drive conveyor 14 made of rollers, a direction change lever 15, and a guide plate 16/1 provided on the upper inner side of the drive conveyor.
It consists of 6', 17.17'. Direction change bar 15
The packaging boxes A, which are sent out from the descending conveyor table 9 by the delivery belt 9', are alternately rotated by 90 degrees in opposite directions. That is, in FIGS. 2 and 4, when the direction change bar 15 is in the position A, the packaging box body A rotates 90 degrees in the direction of arrow R with the help of the guide plate 16, and the direction change bar 15
When is in the position B, the packaging box body A is rotated 90 degrees in the direction of arrow L by the guide plate 16'. Next, each of the packaging boxes AR and AL is attached to the guide plate 1.
The front portions of the sheets 7 and 17' face each other with the splicing margins 3 and 3 facing each other, and are sent to the crimping device 6 by the drive conveyor 14. The drive conveyor 14 and the fast-feeding belt 7 are driven intermittently in synchronization, and their feeding speeds can be varied depending on the degree of dryness of the paste and other factors.
When the conveyor table 9 sends out the packaging box A, a limit switch (not shown) is actuated to raise the conveyor table 9, and the next packaging box A is fed from the fast-feeding belt 7.

The crimping device 6 connects a drive belt 18 following the drive conveyor 14, the rear portions of guide plates 17 and 17' narrowed to the length of the packaging box body A, and the drive belt 18.
Push-up device 19 and crimping conveyor 2 following 8
It consists of 0. It is conveyed by the drive conveyor 14 and the drive belt 18, and the guide plate 17.1
The two packaging boxes AR and AL, which are gradually brought into close contact with each other by the rear part of 7', are integrated by pasting the seam 3 to the other side end 3a of the opposite tab surface or side surface, and then pushing The device 21 places it on the plate 191 of the lifting device 19 . The plate 191 is moved up and down by the piston 192, and the connected packaging box body _A2 is raised by the thickness of one piece, and at this position is supported from below by the stopper 22. When several (four in FIG. 3) connected packaging boxes A ₂ are pushed up, the uppermost packaging box A ₂ is pushed into the crimping conveyor 20 by the pushing device 21', and the crimping conveyor 20 section While passing through, the two packaging boxes A and A are completely stuck together. Incidentally, both the pushing devices 21 and 21' operate in conjunction with each other.

In this way, a packaging box body _A2 which is connected as one package as shown in FIG. 5 is obtained, but this packaging box body
A ₂ can be easily separated by cutting the 3 connecting parts with a knife or by separating the pre-cut machined lines, and after separation, each box functions as one packaging unit. It is also used for transporting small quantities of goods, and does not cause any inconvenience in terms of appearance.

In the above embodiment, the description has been given to the packaging box in which the product is already stored, but it is possible to connect two packaging boxes even if the product is not stored, that is, the inner and outer top flaps are not closed. Not even. Furthermore, by making some changes to the storage line and the connecting device, it is also possible to connect three or more packaging boxes into one package. In this case, it is necessary to make another seam by cutting a part of the side surface or the tab surface of the packaging box excluding both ends, and two gluing rollers are also required.

The above example is a case where a vinyl acetate emulsion type adhesive is used as the glue, and when using a hot melt adhesive with a short effective adhesive time, the time from application of the glue to adhesion, that is, the process, can be shortened. It is necessary to do so.

Furthermore, when using a vinyl acetate adhesive, a brush or a spray gun can be used instead of the gluing roller, and unlike the above embodiments, the packaging box body can be moved horizontally or obliquely and the gluing roller or other glue applicator can be used. may be moved up and down. Further, a turntable may be used as the direction changing device.

In this case, the center of the packaging box is stopped at a position slightly forward or backward from the center of rotation of the turntable, and then the turntable is lifted from below and rotates the packaging box 90 degrees. Next, the turntable is lowered and the packaging box is transported forward by a roller conveyor. The box body to be connected to this packaging box body is also stopped at a position slightly forward or rearward of the center of rotation of the turntable, and the turntable is lifted upward, returned to its original position 90 degrees, and then lowered again. This is accomplished by repeating this process.

Furthermore, it is also possible to slightly shift the center of every other packaging box and rotate it 180 degrees using a turntable.

The present invention provides a case in which two cardboard packaging boxes are placed facing each other at the side end of either the tab surface or the side surface of a cardboard packaging box body in which the tab surface and the side surface are configured as a series. One is made by connecting two pair case packaging boxes each having a protruding connection margin that is attached to the other side edge of the other side or the other side.
When packaging, glue is applied to the inside of the joint between the packaging boxes placed at the rear of the box manufacturing line and storage line and sent in one after another, and a direction changing device is used to turn them facing each other or after the direction is changed, the glue is applied. Since the method involves applying the coating and then crimping and connecting the two packaging boxes, it is possible to connect the two packaging boxes extremely quickly and reliably from the box manufacturing line or even the product storage line. This has excellent effects such as helping to reduce costs and transportation costs.
