[0014]

According to the assembling apparatus of the present invention having the above structure, when assembling the cardboard paper A shown in FIG. 9A, for example, the cardboard B in the state of FIG. Assembled automatically. That is, in FIGS. 1 to 4 and 10, the suction means 52 of the box moving device 5 sucks the box (pattern) A in the unfolded state, so that the suction means 52 is positioned above the pair of base plates 13 located at both ends of the box. The guide members 30
And is placed on the base plate 13. When the unfolded pattern A descends between the pair of guide members 30, the front A 2 and the flap surface A 5 are bent upward at right angles along the fold lines C on both sides of the bottom surface A 1, and the back A 3 and the lid The surface A4 is bent upward at right angles. Therefore, the moving device 5 includes a pair of guide members 30.
Together with 30, it acts to fold the box along the fold lines C on both sides of the bottom surface A1.

Adhesive coating means 1 located in front of inner layer end face A6 connected to both ends of front face A2 of the box.
5 moves along the vertical fold line D between the front face A2 and the inner layer end face A6, whereby the inner layer end face A6 is bent inward at a right angle along the vertical fold line D. Subsequently, of the pair of pressing means 31 and 32, the pressing means 31 located on the side opposite to the inner layer end face A6 moves forward and comes into contact with the back surface A3 of the box. In this state, the pushing member 22 provided on the adhesive applying means 15 advances inward and pushes the inner layer end face A6. Subsequently, after the other pressing means 32 moves forward and comes into contact with the front face A2 of the box, the pushing member 22 retreats to the original position. Thus, the inner layer end face A6 is held in a state of being bent inward at a right angle along the vertical fold line D with the front face A2.

The adhesive applying means 15 moves to the original standby position while ejecting the adhesive E from the ejection nozzle 20, so that the adhesive E is applied to the surface of the bent inner layer end face A6.
Is applied.

When the pushing plate 25 turns horizontally inward, the end face A7 of the intermediate layer and the cover face A9 are bent inward at right angles along the vertical fold lines D at both ends of the back surface A3, and the inner layer is bent. The intermediate layer end face A7 is bonded on the end face A6. Thereafter, the pushing plate 25 horizontally turns outward and returns to the original position.

The adhesive applying means 15 reciprocates again,
When returning to the original standby position, the adhesive E
, The folded intermediate layer end face A
The adhesive E is applied to the surface of the substrate 7.

When the pushing plate 28 below the base plate 13 turns vertically upward, the outer layer end face A8 becomes the bottom face A
1 are bent upward at right angles along the vertical fold lines D at both ends, and are bonded onto the intermediate layer end surface A7. Thereafter, the pushing plate 28 turns downward and returns to the original position.

The above-mentioned steps (1) to (6) can be performed simultaneously in parallel on both ends of the box B, or can be performed sequentially on each side of the box B. In addition, the order of the above steps can be reversed (replaced), or the above steps can be performed between the above steps. Furthermore, the form of the box that can be assembled with the device of the present invention is not limited to the one shown in FIG. 9 described above.
2 and a back A3, a bottom A1, a front A2
And end faces A6, A7, A8 at both ends of the rear face A3, respectively.
What is necessary is just to have.

In the assembling apparatus according to the second aspect, when the lengths of the boxes to be assembled are different, the position of one of the moving units is adjusted so as to be at a predetermined position at the end of the box.
Since the position of the other moving unit also moves to a predetermined position at the opposite end of the box, it is possible to assemble boxes of different lengths and to easily adjust the position of the moving unit. In addition, when the boxes to be assembled have different depths, it can be easily coped with by adjusting the distance between the guide members.
