Further, the holder elevating device 3 is configured to move the upper frame holder 1 and the bottom plate holder 2 up and down using air cylinders 31 and 32, and is equipped with guide rods 33 and 33 that guide the lifting and lowering. Note that the air cylinder 31 is for primary lifting;
2 is for secondary ascent.

Further, the stopper 4 is provided on the conveyor 6 so as to form a gap 41 through which one separated collapsible container 7 can pass.

Further, the guide 5 is for substantially aligning the collapsible container 7 transported by the transport conveyor 6 with the upper frame holder 1.

Further, the conveyor 6 is a drive roller conveyor, and is driven by a motor equipped with a clutch and brake.

Since the collapsible container separation device of the present invention is configured as described above, for example, as shown in FIG. The left and right side plates 73, 7 can be attached to the left side and folded in half at the middle.
3 and front and rear plates 72, 72 whose lower ends can be rotated inwardly and upwardly with respect to the upper frame 71, and the foldable containers 7 assembled in the order of A, B, and C in the figure are stacked. When supplied, it can be suitably used to separate stacked collapsible containers 7 one by one.

Next, a description will be given of a manner in which the collapsible container having the above-mentioned configuration is separated using the collapsible container separating apparatus of the embodiment having the above-described configuration.

The collapsible container 7 (hereinafter referred to as a container) supplied onto the conveyor 6 is conveyed by the conveyor 6 in the direction indicated by the arrow in FIG. 2, and is stopped at a predetermined position by the stopper 4. In this embodiment, a large number (22) of containers 7 are stacked and supplied, but it goes without saying that this embodiment can be applied as long as two or more containers 7 are stacked.

When the container 7 stops, the upper frame holder 1 and the bottom plate holder 2 move forward in the direction of holding the container 7 by the air cylinder 12, as shown in FIG. At this time, the engaging convex portion 13 of the upper frame holder 1
is located at a position corresponding to the engagement recess 74 of the container 7 in the second tier from the bottom of the containers 7 stacked on the conveyor 6, so the upper frame holder 1 is attached to the container 7.
The upper frame 71 can be held securely. At the same time, the holder 24 of the bottom plate holder 2 holds the bottom plate 75 of the second container 7 from the bottom by the force of the spring 23 (see point A in FIG. 4).

Next, the upper frame holder 1 and the bottom plate holder 2 are raised by the secondary lifting air cylinder 32 of the holder lifting device 3, and the containers 7 and 2 in the first stage from the bottom are lifted.
