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 reduces the number of types of packaging boxes, standardizes their sizes, and reduces the minimum number of boxes required to handle the product to 1 ([li
If a large quantity of products is required, the number of boxes can be increased without changing the size of the box, and these packaging boxes can be packed in l packaging boxes for convenient handling such as storage and transportation. That is.

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 of scratches on the product due to the band digging into it, and in the case of tape, it has a number of drawbacks, such as peeling off and spoiling the aesthetic appearance.

Therefore, the present inventors have developed a packaging box made of cardboard such as corrugated paper (JI
Various pair cases in which two or more packaging boxes are connected by protruding one or several connecting allowances on the tab surface, side surface, or inner flap of the A type and B type in S. We have developed a packaging box for

By the way, these boxes were originally made as a single independent box, so in order to achieve the intended purpose, it is necessary to remove them after making the box or after storing the product. It is necessary to connect the boxes.

The present invention provides the first packaging box among the above-mentioned various pair case packaging boxes.
As shown in the figure, the tab surface (1), (1)' and the side surface (2)

A) ・There is also a crimping device (6) that crimps by applying (A) close light.

The glue applicator (4) consists of a fast-feed belt (7), a glue roller (8), and a conveyor table (9) that moves up and down.

The fast feed belt (7) is the feed belt at the tip of the storage line (
The packaging boxes (A) and 1 are stretched adjacent to the feeding belt at the same level as the feeding belt, and are fed out one after another from the storage device (not shown) and placed on the feeding belt (1). ... with the stopper (11) and the detection limit switch (11)

transport upwards. The conveyor stand (9) consists of roller conveyors (91) arranged around the length of the packaging box body (A) and having a small diameter and shorter than the width of the packaging box body.
), and the roller conveyor (91) is stopped at the same or slightly lower level than the rapid-feeding belt (7).

The packaging box body (A) sent from the fast-feeding belt (7) is placed on the roller conveyor (91), and is placed on the conveyor stand (
9) When the limit switch (13) on the upper end of the vertical guide plate (12) installed at the rear is pressed, the conveyor table (9) descends, and on the way, the roller (8) is used as an applicator to apply glue to the packaging box body. Apply glue to the inside of the connecting gap (3) in (A). Note that (8) in the figure is a guide roller for gluing. The vertical movement of the ring body (82) is performed by a cam, a gear motor, etc. Next, the packaging box body (A) is moved by a driving conveyor (
14) to the direction change device (5).

The direction change device (5) includes a drive conveyor (14) consisting of rollers, a direction change bar (15), and guide plates (1G)' and (lft)' provided on the upper side of the drive conveyor.
, (17) and (I7)'. Direction change bar (15
) is the delivery belt (
9) The packaging boxes (A) sent out by '' 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) is rotated 90 degrees in the direction of arrow R with the help of the guide plate (+6). Rotate and use the direction change bar (15
) is in the position (b), the packaging box (A) is rotated 90 degrees in the direction of the arrow by the guide plate (16)'. Next, the packaging boxes (AR) and (AL) are placed facing each other by the front parts of the guide plates (17) and (+7)', respectively, with the seams (3) and (3) inside. , to the crimping device (6) by a drive conveyor (14). The drive conveyor (14) and the fast-feeding belt (7) are driven intermittently in synchronization, and their feeding speeds are variable depending on the degree of dryness of the paste and other factors. The conveyor table (9) moves up when the conveyor table (9) sends out the packaging box (A), and the next packaging box (A) is fed from the fast-feeding belt (7).

The crimping device (6) is connected to the drive bell (18) following the drive conveyor (14) and the rear part of the guide plates (17) and (17)' which are narrowed to the length of the packaging box body (A,). , a push-up device (18) and a crimping conveyor (20) following the drive belt (+8). Drive conveyor (I4
) and the drive belt (+8), and the 2 (solid packaging box body (AR) / (AL) is conveyed by the rear part of the guide plate (17) / (17> ) are attached to the side edge (3a) of the other claw surface or side surface of the other party and are integrated, and the plate (19) of the push-up device (+9) is pressed by the push-in device (21).

is raised by one thickness, and at that position is supported from below by a stopper (22). When several (four in Fig. 3) connected packaging boxes (A2) are pushed up, the uppermost packaging box (A2) is pushed up by the pushing device (21).
)' into the crimping conveyor (20), and while passing through the crimping conveyor (20) section, the two packaging boxes (A)
- (A) is completely pasted. 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 (A2)
It can be easily separated by cutting the connecting margin (3) with a knife or by separating the pre-engraved perforation lines, and after separation, each box functions as one packaging unit and can be used for small quantities. It is also used to transport 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 gluing also requires 21 rollers.

Note that 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. In order to do this, the glue applicator is placed behind the direction changing device, and for example, until the packaging boxes (AR) and (AL) facing each other with the joints (3) inside are brought close to each other. It is necessary to temporarily stop the process and apply the Honmelt to the inside of the joints (i) and (3) using a coating tool such as a spray gun.

In addition, in order to bond within the effective bonding time (usually several to tens of seconds) after applying the glue, close pressure is applied immediately from the above-mentioned facing state to press the connecting margin to the corner surface or side surface of the other box body. There is a need.

However, if the direction change device is located in front of the glue applicator, two sets of glue rollers and spray guns are required. In this way, the glue applicator in the above embodiment becomes unnecessary, and the packaging box body (A) can be fed to the direction changing device directly from the feeding bell 1-(10) or via the fast-feeding belt (7). Also, since the adhesive is bonded immediately, the crimping process can be shortened. However, when using a hot melt adhesive with a long open time, it is also possible to use the apparatus of the above embodiment. Furthermore, if the gluing is applied only to the rear one of the two packaging boxes, the time from gluing to adhesion can be somewhat shortened. However, in this case, it is necessary to apply glue to the inner side of the connecting area (3) and the connecting area pasted part (3a) of the rear packaging box body.

Furthermore, when using a vinyl acetate adhesive, a brush or spray gun can be used instead of a roller for gluing, and unlike the above embodiments, the packaging box body is moved horizontally or inclined, and gluing can be done using rollers or other means. The glue applicator 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 body and rotate it by 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. Two packaging boxes for a pair case each have a protruding connection margin that is attached to the side edge of the other side or the other side.
When connecting individual boxes to form one package, glue is applied to the inside of the joint between the packaging boxes that are placed behind the box making line and the storage line and are sent in one after another, and a direction changing device is used to turn them facing each other or to change the direction. After conversion, glue is applied and the two packaging boxes are then crimped and connected, so the two packaging boxes can be assembled very quickly and reliably from the box manufacturing line or even the product storage line. It has excellent effects such as being useful in reducing packaging costs as well as transportation costs.
