[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

1 to 3 show a pair case manufacturing apparatus 1 according to the present invention.
This is an embodiment of the present invention, which is placed behind a box manufacturing line or a line for storing products in boxes. This is provided with an introduction conveyor 3 connected to the above line and for introducing the packaging boxes 2 into the apparatus. The packaging box body 2 carried in by the introduction conveyor 3 is moved to the rotating device 4 by the second stopper 32 at the terminal end of the introduction conveyor 3.
It is stopped so that it is located directly below. When it is necessary to stop the packaging boxes 2 that are sequentially carried in by the introduction conveyor 3 before the rotating device 4, the packaging boxes 2 are stopped at the first stopper 31 provided in the middle of the introduction conveyor 3, and the rotation is first stopped. Device 4
After discharging the packaging box bodies 2 located directly under the rotating device 4, the stop is released and the packaging boxes 2 are fed one by one directly under the rotating device 4. In this case, the first stopper 31 may be provided between the line and the introduction conveyor 3, that is, at the tip of the introduction conveyor 3, and the packaging box body 2 may be retained on the line. Further, the middle part of the introduction conveyor 3 is made to be able to rotate in the vertical direction, and when stopping the packaging box body 2, it is rotated downward and the packaging box body 2 is stopped by hitting the frame of the device or the like. You can.

Next, the packaging box body 2 located directly below the rotating device 4 is rotated by the rotating device 4 by 180 degrees. As shown in FIG. 4, this rotating device 4 is configured to rotate a chuck 42 provided with clamping portions 41, 41 by a rotary actuator 43, and to move it up and down by an elevating cylinder 44.

In the case of the rotating device 4 of this embodiment, the packaging box body 2 is held between two diagonal ridge lines of the holding part 41 having an angular cross section. Alternatively, the opposing tab surfaces or opposing sides of the packaging box 2 may be pressed, but if the packaging box 2 is heavy or the material is not very strong, the surface may be affected by friction. Since it is expected that the material will wear out, the structure shown in the drawings is preferably used in that case. The rotation method using this rotating device 4 is as follows: First, the chuck 42 is lowered by the elevating cylinder 44, and after the packaging box body 2 is clamped by the clamping parts 41, the chuck 42 is raised. Then, after rotating the chuck 42 by 180 degrees using the rotary actuator 43, the chuck 42 is lowered again, the packaging box body 2 is released from the clamping part 41, and the chuck 42 is raised and placed on standby. In addition, when clamping the tab surface or side surface of the packaging box body 2, if the height of the packaging box body 2 is approximately constant or if the effective length of the clamping portion of the clamping part 41 is lengthened, the lifting and lowering is not possible. The cylinder 44 may not be provided. Further, it is preferable that the holding parts 41 can be arbitrarily articulated at intervals depending on the width of the packaging box body 2.

The packaging box body 2 rotated by 180 degrees is pushed out laterally by a pushing cylinder 5 provided on the side of the introduction conveyor 3. The glue applicator 6 applies glue to the connecting margin 25 and the connecting margin sticking portion 26 of the packaging box body 2 at this pushed-out position. This glue application device 6 is provided with two spray guns 61 for spraying glue onto both the connecting margin 25 and the connecting margin sticking portion 26, and sprays the adhesive while moving up and down with a cylinder 62 for raising and lowering each gun. I try to spray it on. The packaging box body 2 coated with the glue in this manner is moved by the polymerization device 7 to the side of the tab surface 21 on which the connecting margin 25 is protruded.

Furthermore, the next packaging box body 2 positioned directly below the rotating device 4 is pushed out by the pushing cylinder 5 without being rotated by the rotating device 4. As a result, the side surfaces 23 and 24 of the previous packaging box 2 and the next packaging box 2 come into contact with each other. This is because by moving the previous packaging box 2 in the polymerization device 7, the tab surface 21 of the previous packaging box 2 and the tab surface 22 of the next packaging box 2 are not on the same straight line. It is.

Then, the two packaging boxes 2 whose side surfaces 23 and 24 are in contact with each other are pressed from the lateral direction by the pressing means 8.
The connecting margin 25 and the connecting margin sticking portion 26 are adhered to each other to form a pair case 27. 'The pair cases 27 thus formed are sequentially discharged out of the apparatus through the packaging boxes 2 which are sequentially pushed out by the pushing cylinder 5.

In this embodiment, when the pressure means 8 presses the two packaging boxes 2 from the lateral direction, pressure is applied from the upper part of the packaging boxes 2 in order to force vertical displacement during adhesion. It is pressed by a cylinder 81. In addition, the number 82 in the figure is a manual discharge motor.
This is a drive device for feeding the pair case 27 out of the device by manual operation.

FIG. 5 shows an example of a packaging box provided for the apparatus of the present invention, and shows the tab surface 21 of an A-shaped cardboard box body in which the tab surfaces 21, 22 and side surfaces 23, 24 are configured in series.
A connecting portion 25 is provided protruding from the side end portion of. By arranging these two packaging boxes 2 to face each other, the connecting margins 25 are adhered to the connecting margin adhesion portions 26 at the side ends of the other tab surfaces 24 on the opposite side. The collection box thus obtained is a pair case 27 shown in FIG.

Furthermore, in the above embodiment, the description has been made regarding 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. Needless to say. Furthermore, it is also possible to make one package by connecting three or more packaging boxes by making some changes to the storage line and the connecting device. In this case, it is necessary to make a notch in the side surface or a part of the tab surface of the packaging box excluding both end portions to form another connecting margin.

[Effects of the Invention] As described above, the pair case manufacturing device according to the present invention has a packaging box made of cardboard, in which the tab surface and the side surface are configured in series, and the side end of either the tab surface or the side surface. When two cardboard packaging boxes are placed facing each other, two packaging boxes each having a protruding connection margin that is attached to the other side edge or side surface of the other are connected to form one package. In this process, the packaging boxes are placed behind the box manufacturing line and the product storage line, and the packaging boxes are alternately rotated 180 degrees so that they face each other, and these connecting margins are used to connect other packaging boxes. Since the two packaging boxes are bonded to the area where they are pasted to form a pair of cases, it is possible to connect two packaging boxes very quickly and reliably from the box manufacturing line or even the product storage line, reducing packaging costs and transportation costs. This is useful for reducing

Further, in the present invention, since the pushing cylinder is provided on the side of the introduction conveyor, the flow of the packaging box body is L-shaped, so there is an advantage that the installation space of the present device does not need to be large. Furthermore, since the configuration is such that a push cylinder is used to feed the formed pair case to the crimping part of the packaging box body and to discharge the formed pair case, the structure is extremely simple.
This has the excellent effect of making the device itself more compact.
