BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to the illustrated embodiments. The box assembling apparatus and the assembling method according to the present embodiment relate to an assembling apparatus and an assembling method for a B-type case using cardboard. As shown in FIG. 1, here, the packaging box is assembled by a horizontally long first plate-like body 11 made of cardboard and a vertically long second plate-like body 12 also made of cardboard.
[0010]
The first plate-shaped body 11 has a front plate 16 substantially at the center thereof, side plates 17 and 18 are continuously provided on both sides thereof, and joint pieces 19 and 20 are further provided on the distal ends of the side plates 17 and 18. I have. These are connected to bendable by bending lines.
[0011]
On the other hand, the second plate-shaped body 12 has a back plate 22 substantially in the center thereof, a bottom plate 23 below the lower plate 22, and a lid plate 24 above the upper plate. Further, flaps 25 and 26 are continuously provided at the distal ends of the bottom plate 23 and the cover plate 24, respectively.
[0012]
Next, the operation of assembling the B-type case using the first plate 11 and the second plate 12 will be described. As shown in FIG. 1A, one side plate 18 of the first plate-shaped body 11 is bent so as to overlap the upper side of the front plate 16, and the joining piece 19 on the tip side of the opposite side plate 17 is oriented in the same direction as the side plate 18. Fold so that it becomes. Then, a paste 28 is applied to the surfaces of the joining pieces 19 and 20 respectively.
[0013]
Thereafter, as shown in FIG. 1B, the folded first plate 11 is overlapped with the inside of the back plate 22 of the second plate 12, and the joining pieces 19, 20 coated with the glue 28 are joined together. Align with both ends of back plate 22. Then, the first and second plate-like members 11 and 12 are joined as shown in FIG. 1C by gluing and joining the joint pieces 19 and 20 to the back plate 22.
[0014]
Thus, three sides of the side surface of the box are formed by the first plate-shaped body 11. Accordingly, by closing the bottom opening with the cover plate 23 of the second plate-shaped body 12 and closing the upper opening with the cover plate 24, the B-type case is assembled as shown in FIG. 1D. The assembling apparatus and the assembling method according to the present embodiment, as shown in FIG. 1A, bend the first plate-like body 11 and apply the glue 28 to the joining pieces 19 and 20 and then apply the second plate-like body. The process up to the step of overlapping the back plate 22 of the body 12 as shown in FIG. 1B is performed. Then, the box assembled in a flat folded state as shown in FIG. 1B is supplied, and immediately before use, as shown in FIGS. 1C and 1D, the box is assembled three-dimensionally and used as a box.
[0015]
Next, the overall configuration of the box assembling apparatus will be described with reference to FIG. This assembling apparatus is provided with a gantry 30 extending long in the direction of the assembling process, and a hopper 31 and a bending unit 32 are vertically arranged on the front end side and at the top. A gluing unit 33 is disposed behind the hopper 31 and the bending unit 32. The gluing unit 33 is a unit that glues the glue 28 supplied from the glue tank 34 by the supply pipe 35 to the joining pieces 19 and 20 of the first plate-like body 11.
[0016]
A hopper 36 is disposed behind the gluing unit 33, and the hopper 36 supplies the second plate-like body 12. Then, the first plate-like body 11 and the second plate-like body 12 are pressed in the direction of overlapping in the pressure-accumulating unit 37, whereby they are glued and joined by the glue 28 applied to the joint pieces 19 and 20. It has become.
[0017]
Here, if the gluing positions of the joining pieces 19 and 20 of the plate-like body 11 are scratched in advance and glued at the place where such a scratch is made, the permeability or adhesiveness of the glue is improved. Instead of gluing to the joining pieces 19 and 20 of the plate-like body 11, gluing may be performed at the bonding position of the back plate 22 of the second plate-like body 12 on the opposite side.
[0018]
It is preferable that the paste applied to the bonding position between the first plate 11 and the second plate 12 is starch paste. This is a relatively long solidification time of about 3 to 5 seconds for starch paste, so that the first plate 11 and the second plate 12 are glued in a state where they are displaced from each other. However, this is because the relative displacement between the first plate-shaped body 11 and the second plate-shaped body 12 is corrected by the upright guides 57 and 58 of the accumulation unit 37 described later. Here, if a quick-drying adhesive such as hot melt is used, it is somewhat difficult to correct the positional deviation by the upright guides 57 and 58 of the pressure and pressure unit 37. In this regard, it is preferable that the starch paste is applied by the gluing unit 33.
