Abstract

A planar storage facility is provided with a storage/retrieval device for suspending and transporting storage items between a desired position in a storage item placement plane and a storage conveyor and a retrieval conveyor. A plurality of passage regions dividing the storage item placement plane into small areas are established in the storage item placement plane. At least one end of the passage regions opens to the outside of the periphery of the storage item placement plane. The task of manually unloading the storage items in the small areas can be performed from within the passage regions forming the small areas.

First claim

What is claimed is:

1. A planar storage facility comprising:
a storage item placement plane;
a storage conveyor;
a retrieval conveyor; and
a storage/retrieval device which lifts and transports a storage item between a desired position on the storage item placement plane and the storage conveyor and the retrieval conveyor,
wherein a plurality of passage regions dividing the storage item placement plane into small areas are established in the storage item placement plane, and at least one end of the passage regions opens to an outside of a periphery of the storage item placement plane and each passage region is configured such that an operation of manually transporting out a storage item stored in one of the small areas can be performed from within an associated passage region by transporting the storage item in a horizontal direction, via the associated passage region, to the outside of the periphery of the storage item placement plane.

2. The planar storage facility according to claim 1 ,
wherein each of the small areas is set to have an area such that the operation of manually transporting out the storage item in the small area can be performed from the passage region or the outside of the periphery of the storage item placement plane without an operator entering the small area.

3. The planar storage facility according to claim 1 ,
wherein in a full state where the storage items are stored in all of the respective small areas, the storage/retrieval device is controlled such that the storage item can be stored into the passage region from an innermost section of the passage region farthest from an open end which opens to the outside of the periphery of the storage item placement plane.

4. The planar storage facility according to claim 1 ,
wherein the storage item placement plane is divided into a plurality of storage regions according to planar sizes of the storage items, the small areas are established within each of the storage regions by the passage regions, and the storage item to be stored is stored into the small area selected within the storage region compatible with the planar size of the storage item.
