Next, the operation of the machine of the present invention having the above-mentioned configuration 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 presser bar 12. When the foot switch 20 is turned on, the air cylinder 15 first operates downward, pushing down the container pressing body 13 via the arm 11, and the container pressing body 13 covers the outer surface of the uppermost container 2B. After that, the entire container 2 is pressed while resisting the elasticity of each container 2, and the inner surface and the outer surface of each adjacent container 2 are brought into close contact with each other. The pressing force is about 30 kg / cm ² , and each container 2 The limit switch 23 detects the lower limit of the container pressing body 13 when only the outer side surface of the inlet peripheral portion 2'is made to adjoin, and operates so as to stop the pressing of the container pressing body 13. Note that the presser bar 12 also descends by its own weight in conjunction with the pressing of the container pressing body 13, and the lower end of the presser bar 12 continues to press 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 activated and the turntable 8 is rotated, and at the same time, each spray gun group 18 is activated to transfer 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 rotates, for example, two times, the limit switch 21 detects it and stops the operation of the motor 6, and at the same time, the turntable 8, the container pedestal 9, the stacked container group and It operates so as to stop the rotation of the container pressing body 13. Then, immediately after the lapse of time set by the timer (not shown in the figure), the air cylinder 16 operates upward and pushes up the container pressing body 13 via the arm 11, and the container pressing body 13 reaches the uppermost position. Separate from container 2B. Then, at the same time that each container 2 floats up due to their elasticity, 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 portion 2'of each container 2. The containers 2 on which the application of the adhesive 4 has been completed as described above are moved 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. The space between the container support 9 and the presser bar 12 and the pressing force of the container pressing body 13 may be adjusted according to the number of containers to be stacked. The number of spray guns and their intervals should be increased or decreased depending on the number of containers to be stacked.

[Effect of device]

 Since the present invention is configured as described above, a large number of containers are stacked on a container support provided in the center of the turntable, and the stacked container group is pressed by pressing the container pressing body on the uppermost container. This makes it possible to bring the inner surface of each container into close contact with the outer surface of each container so that only the inlet peripheral edge of each container is adjacent, and the adhesive is sprayed from diagonally above the adjacent inlet peripheral edge. Since it can be ejected by the gun group, the adhesive is applied only to the peripheral edge of each inlet, does not enter the overlapping part of each container, and when the pressing by the container pressing body is released after the adhesive is applied, each container is Due to their resilience, they are slightly lifted so that the peripheral edge portions of the inlets are separated from the adjacent state, and there is no place where the containers are bonded to each other as in the conventional example. Therefore, a large number of containers are stacked. , In a state where the sideways, it is possible to provide a container stacking products that can be removed reliably containers from a subsequent container group sequentially one by one.
