Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to cartons, containers, lids, etc. (hereinafter referred to as packaging materials).
It is a partition that divides the inside of the returnable box into several compartments when it is packed in a returnable box such as a cardboard box or a plastic box (hereinafter referred to as returnable box). The present invention relates to a partition and a partition of a packing material return box.

(Prior art) Dozens to hundreds of packing materials are packed in returnable boxes and transported from the packing material manufacturing plant to the place where they are used. , The interior of the returnable box is divided into several stages or rows by partitioning.

(Problems to be solved by the invention) In the conventional dividers, which divide the inside of the returnable box, the corrugated cardboard and the like are erected to form rows, and the corrugated board is laid out in a flat plate shape. The packaging material was taken out manually.

Therefore, with the conventional partition shape of the returnable box, even if the packaging material is to be automatically taken out by a robot or the like, the middle partition does not have a gripping portion or a supporting portion, so the middle partition must be removed manually. Moreover, since there is no gap between the packaging material and the inner surface of the returnable box, there is a problem that the returnable box is damaged, and there is a problem that the conventional partition structure cannot be automated.

The present invention was devised in view of such a point, and after the packaging material is clamped and taken out from the inside of the return box by the robot in a row unit, or vacuum suction is performed, the partition is removed by the robot. The purpose of the present invention is to provide a partition that can be fully automated for taking out.

(Means for Solving the Problem) In order to achieve the above-mentioned objects, the present invention solves the problem by improving the partition of the packing material return box.

That is, in the present invention, the step dividing plate and both side plates thereof are provided with a folding line which is folded from the center in the direction of both side plates, and the row dividing plate is pivoted along the folding line of the step dividing plate. The row partition plate is provided with a through hole for inserting at least one fork claw, and the step partition plate is provided with at least one air through hole on both sides of the central folding line. On both side plates of the above, a means for allowing the take-out member for taking out the packaging material on the step partition plate to pass is provided at symmetrical positions on both sides of the center folding line. The take-out means is a gripping piece of a robot or a vacuum suction section, and the take-out means for inserting these take-out means include a notch portion from the upper edge of the side plate and a spacing member attached to both sides thereof. Depends on
