[Conventional technology]

The above collective packaging box is 1. Since it can be transported or stored as it is, an outer box is not required during transportation or storage, and it is economical because it saves the trouble of storing it in an outer box.

A prior art method for manufacturing such collective packaging boxes is disclosed in Japanese Patent Publication No. 8978/1983. In this manufacturing method, in the process of transporting the box (unit box),
A predetermined number of boxes are assembled by extruding in a direction perpendicular to the feeding direction, the upper flap of the assembled boxes is folded down, and adhesive is applied to the upper surface and the sides of the boxes, and the assembled boxes are A lid plate is placed on top of the lid plate, and both sides of the lid plate are bent and adhered to the sides of the box body and the flap, respectively.

[Problem that the invention seeks to solve]

By the way, in the above manufacturing method, since the structure is such that the boxes in which the objects to be packaged (commodities) are stored in advance are conveyed one after another,
As a pre-process to form a collective packaging box, two steps are required: assembling the box from the box blank and storing the objects to be packaged inside the box, and also requires a conveyor device to convey the box. shall be. As a result, the overall size of the device increases, requiring an extremely large amount of equipment space.

Therefore, the present invention solves the above-mentioned inconvenience, houses the colored body inside the box at the same time as the box is assembled, collects a plurality of the boxes, and supplies a common lid blank thereon. However, the technical problem is to reduce the size of the device by assembling the lid blank when both are transferred upward at the same time.

[Means for solving problems]

In order to solve the above problems, the present invention forms a pair of side plates and a pair of knob plates around a bottom plate through a fold line, and forms a pair of side plates at both ends of the side plate through a fold line. A blank conveying process of conveying a box forming part blank configured to achieve a flap and further providing an inner flap on the side edge of the side plate through a fold line to the upper part of the box forming part, and a blank conveying process in which the blank is covered with a bottom plate of the blank. a step of transporting the package, a step of applying an adhesive to at least one of the top surface of the tab plate and the bottom surface of the side flaps of the blank during or after the transport of the box-forming blank, and the step of transporting the blank and the object to be packaged. At the same time, the blanks are assembled in a downward direction to form a box that accommodates the packaged object, and the box is transported with the side panels of the box in the front and the box directed below the lid bottom shape. Then, during the transportation, the inner flaps of the boxes are bent, and the side plates are brought into contact with each other to collect a plurality of boxes, and the lid blank is transported to the top of the assembled boxes. During the transportation, there is a step of applying adhesive to the bottom surface of the lid, and a process of pressing the collection box onto the bottom of the lid blank and simultaneously transporting it upward, and bending both sides of the lid blank during the transfer. It consisted of a step of gluing it to the collection box.

〔Example〕

Hereinafter, the configuration of the present invention will be explained based on the accompanying drawings.

As shown in Fig. 1, the box blank A has a pair of side plates C on both sides of the bottom plate A with the fold lines in between, and a pair of tab plates C on both ends of the bottom plate A with the fold lines above the valves. It is completed. Further, a pair of side flaps d are connected to both end edges of each side plate via a fold line, and an inner flap e is also formed to the side edge of each side plate via a fold line.

The box blanks A are piled up at a predetermined position, taken out one by one from the top or bottom, and supplied to one end on a single parallel rail 1 shown in FIG.

A pair of endless chains 2 with claws are placed between the rails 1, and the box blank A fed onto the rails 1 is
It is conveyed to the other end of the rail 1 by the claws 3 of the endless chain 2 and positioned by the stopper 4.

As shown in FIG. 1, a coating head 5 is arranged in the middle of the transport path of the box blank A. As shown in FIG. This application head 5
is actuated by a signal from a detector (not shown) that detects the passage of the box blank A, and applies adhesive to both sides of the upper surface of the tab C of the box blank A passing below.

FIG. 16 shows the adhesive layer.

On the bottom plate a of the box blank A positioned at the other end of the rail 1, a packaged object B conveyed by a packaged object conveying device 10 is supplied. As shown in FIG. 2, this packaged object conveying device 10 includes a belt conveyor 11 disposed on the side of the other end of the rail 1, and the packaged object B transported by the conveyor 11 to the end of the conveyor. is further conveyed forward by the forward motion of the slide block 13 that is slidably supported along the guide shaft 12 and is supplied onto the bottom plate a of the box blank A.

Here, a bushing 14 is supported by the slide block 13 so as to be movable up and down, and a cylinder 15 for raising and lowering the bushing 14 is supported by the slide block 13. The button 14 descends just before the slide block 13 moves forward, and the movement of the block 13 causes the button 14 to move toward the packaged object B.
When the packaged object n is conveyed to the bottom plate a of the box blank A, it will rise.

Note that the mechanism for moving the slide block 13 back and forth is a swing lever 17 whose one end is rotatably supported by the rotation of an arm 16 that is rotationally driven in one direction.
Although the other end of the swinging lever 17 and the slide block 13 are connected by a link 18, any other arbitrary mechanism may be adopted.

The box blank A that has been conveyed to the other end of the rail 1 is supported by a liftable table 20 arranged below it, and the upper part of the box blank A is When the object to be packaged B is supplied, the presser plate 21 provided above and movable up and down descends and comes into contact with the upper surface of the object to be packaged B during its descent. The presser plate 21 is further lowered from the state where it is in contact with the upper surface of the object to be packaged B, and at the same time, the table 20 is also lowered. Therefore, the box blank A and the packaged object B are transported downward with their upper and lower sides supported.

In this way, since the objects B to be packaged are transferred downward while the upper surface thereof is pressed by the presser plate 21, even if the objects B to be packaged are stacked in double rows and in multiple tiers, the arrangement can be maintained without disrupting the arrangement.
The packaged object B can be transported downward.

Note that a cylinder or the like may be employed as a drive device for raising and lowering the table 20 and the presser plate 21. A molding device 30 for assembling the box blank A is disposed on the downward transport path of the box blank A and the packaged object B. As shown in FIG. 3, this forming device 3o has a side plate bending guide 31 and a knob plate bending guide 32 arranged in a quadrilateral shape.
Each guide 31.32 is provided with an inclined surface 33.34 on its upper inner surface. The lower edge of the inclined surface 33 of the side plate bending guide 31 is located higher than the lower edge of the inclined surface 34 of the knob plate bending guide 32, so that the bending of the side plate precedes the bending of the knob plate C. ing. Further, side flap folding members 35 are arranged on both sides of the side plate bending guide 31, and the folding members 35. is moved diagonally up and down by the operation of the cylinder 36, and is moved upward when the box blank A is transferred downward.

Therefore, when the box blank A is lowered together with the table 20, the side flap d, the side plate and the knob C are sequentially folded by the folding member 35, the side plate bending guide 31 and the knob plate bending guide 32, and the knob plate C is folded in order. The adhesive 6 applied in advance to the side flap d adheres to the side flap d. Therefore, as the box blank A passes through the inside of the forming apparatus, the box A' is assembled as shown in FIG. 1, and at the same time, the packaged object B is accommodated.
