Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reversing and aligning device for multi-tiered stacking, which is suitable for use in aligning multi-tiered articles such as pallets.

Conventional technology Generally, when a forklift is used to transport cargo, the cargo is placed on a pallet made of wood or plastic and transported to the desired location. After use, they are piled up in one place.

These pallets are manually stacked vertically and horizontally in different places, but this requires a great deal of time and effort, so the pallets are left stacked using a forklift. In many cases, the pallets are stacked with some misalignment between them.

When these stacked pallets are transported by a forklift, vibrations during transport can cause the pallets to become even more misaligned, causing them to collapse, causing damage to the pallets and posing a danger to workers. There was a fear that he would invite her.

Problems to be Solved by the Invention In view of the above-mentioned circumstances, it is an object of the present invention to make it possible to easily align stacked pallets without requiring much effort.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a support provided on a stand, a work clamp device for raising and lowering the support towards the stand, and a workpiece clamping device for raising and lowering the support towards the stand.
