In this case, the traveling device has a pair of front and rear posts, and an elevating table that is guided by these posts and is capable of moving up and down is provided with a load transfer tool that can freely move in and out in the lateral direction.

The traveling device combines a traveling movement, a raising and lowering movement of a lift table, and a withdrawal movement of a load delivery tool to provide a cargo handling space provided outside the shelf and a desired compartment storage space. The cargo is being delivered between the two. In this case, when the load is a plate-like object such as an iron plate, the plate-like object is handled in a state of being stacked on a pallet.

[0004]

However, when handling a plate-like object in the above-mentioned automatic warehouse facility, although the pallet unit can be loaded and unloaded by the traveling device, a single plate-shaped article cannot be loaded and unloaded. That is, for example, when only one plate-like object is to be unloaded, first the pallet unit is put out to the loading / unloading area, then one plate-like object is removed from the pallet in the loading / unloading area, and the remaining plate-like objects are removed. It was stored again together with the pallet, and in this case, the traveling device was inefficient and inconvenient because it carried out the storing operation and the discharging operation.

An object of the present invention is to provide a plate-like material storage facility capable of loading and unloading plate-like objects in pallet units as well as loading and unloading a single plate-like object.

When a single plate-shaped product is to be unloaded, first, the loading / unloading tool is moved to the position below the pallet and the suction device is positioned above the plate-shaped group. Then, the loading / unloading tool is lowered together with the carriage to bring the suction device into contact with the upper surface of the uppermost plate-like object. After the suction device is moved by suction, the carriage is slightly raised to lift the uppermost plate-like object. In this state, the loading / unloading tool is moved into and out of the carriage to be transported to the loading / unloading area.

In the loading / unloading area, the loading / unloading tool is moved so as to be positioned above the plate-shaped receiving portion, and the loading / unloading tool is lowered together with the carriage to be placed on the plate-shaped receiving portion. And after releasing the adsorption of the adsorption device,
The carriage is raised slightly to separate the suction device from the plate-like object. After that, the loading / unloading tool is moved into and out of the carriage. It should be noted that the reverse operation described above enables the storage of a single plate-shaped object.
