Next, the operation of the machine of the present invention having the above-mentioned structure will be explained. With the power source turned on, for example, 50 containers 2 are stacked, and the inner surface of the lowest container 2A is placed on the container receiving base 9 Then, the central portion of the outer surface of the uppermost container 2B is pressed by the lower end of the pressing rod 12. And
When the foot switch 20 is turned on, first, the air cylinder 15 operates downward, and the container pressing body 1 passes through the arm 11.
3 is pushed down, the container pressing body 13 is the uppermost container 2
After covering the outer surface of B, the entire container 2 is pressed against the elasticity of each container 2 to press the inner surface and the outer surface of each adjacent container 2 tightly, about 30 kg / cm ² When the limiter 23 detects the lower limit of the container pressing body 13 and presses down the container pressing body 13, the limit switch 23 operates to stop the pressing of the container pressing body 13 when only the outer side surface of the inlet peripheral portion 2'of each container 2 is adjacent. To do. In addition, the presser bar 12 also descends by its own weight in conjunction with the pressing of the container pressing body 13.
The lower end of the container keeps pressing the center of the outer surface of the uppermost container 2B. Then, immediately after the elapse of the time set by the timer (not shown), the motor 6 is operated to rotate the turntable 8, and at the same time, each spray gun group 18 is operated to apply the adhesive 4 to each container. It spouts toward the outer side surface of the inlet peripheral portion 2'of No. 2. Then, the container pedestal 9, the stacked container group, and the container pressing body 13 rotate in synchronization with the turntable 8, so that the adhesive 4 is applied along the outer surface of the inlet peripheral portion 2 ′ of each container 2. In this process, when the turntable 8 makes two turns, for example, the limit switch 21
Detects that and stops the operation of the motor 6, and at the same time, operates so as to stop the rotation of the turntable 8, the container support 9, the stacked container group and the container pressing body 13. Then, immediately after the lapse of the time set by the timer (not shown), the air cylinder 16 operates upward and pushes up the container pressing body 13 via the arm 11, and the container pressing body 13 is the uppermost container. Move away from 2B. Then, each container 2 floats up due to their elasticity, and at the same time, the uppermost container 2B pushes up the presser bar 12 that holds the center part of the outer surface thereof, and the adjacent inlet peripheral edge parts 2 of each container 2 are pushed up. ′ Are slightly separated from each other, and the containers 2 are supported in a stacked state by the pressing of the presser bar 12, and there is no part where the overlapping parts of the containers 2 are bonded with an adhesive. Then, when the container pressing body 13 reaches the upper limit position, the limit switch 22 detects it and operates so as to stop the upward movement of the air cylinder 16. The above operation can be repeated as one cycle to repeatedly apply the adhesive 4 to the outer surface of the inlet peripheral edge portion 2 ′ of each container 2. The containers 2 on which the application of the adhesive 4 is completed as described above are transferred to the step of drying the adhesive 4 while being stacked.

In the present invention, the container 2 may be a container formed of plastic other than foamed plastic. Further, the turntable 8 may be configured to be switched between automatic rotation and manual rotation, or may be configured to be only manual rotation. Also, the container support 9 and the presser bar 12
The interval between the and and the pressing force of the container pressing body 13 may be configured to be adjusted according to the number of containers to be stacked. Further, the number of spray guns and their intervals are appropriately increased or decreased depending on the number of containers to be stacked.

[0009]

[Effects of the Invention] The present invention was constructed as described above.
A large number of containers are stacked on a container cradle provided in the center of the turntable, and the stacked container group is pressed by covering the uppermost container with a container pressing body to press each container on the outer surface of each container. Since the inner side surfaces can be brought into close contact with each other so that only the inlet peripheral edge portions of the respective containers are adjacent to each other, and furthermore, the adhesive can be jetted by the spray gun group from diagonally above the adjacent inlet peripheral edge portions, the adhesive is It is applied only to each inlet peripheral part, does not enter the overlapping part of each container, and when the pressing by the container pressing body is released after the application of the adhesive, each container is slightly lifted by their elasticity, and each inlet peripheral part is Unlike the conventional example, there is no place where the containers stick to each other apart from the adjacent state.Therefore, in the state where many containers are stacked and laid sideways, It is possible to provide a container stacked products can be removed reliably sequentially one by one from the vessel group.
