BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional storage facility for automatically loading and unloading a load from a shelf.

[0002]

2. Description of the Related Art Heretofore, loading and unloading of a load to and from a shelf of a three-dimensional storage facility of this type has been carried out by a stacker crane.
That is, the shelf has a plurality of storage sections provided in the horizontal direction in a plurality of upper and lower stages, and the stacker crane is arranged in front of the shelf so as to be horizontally movable. The stacker crane is provided with a vertically movable loading platform, and a fork for transferring a load between the storage section and the loading platform is provided on the loading platform so as to be retractable.

According to this, by moving the stacker crane horizontally and raising and lowering the loading platform,
The loading platform faces the intended storage area. After that, the load is delivered to the intended storage unit by retracting the fork.

[0004]

However, in the above conventional type, since the stacker crane moves the load up and down, moves horizontally, and transfers the load, when the load is heavy and the shelves are high, the load is lifted and leveled. There is a problem that a large load or moment is applied to the stacker crane that travels in the direction, so that the stacker crane becomes extremely large and the travel route of the stacker crane expands, and the entire three-dimensional storage facility becomes large.

Further, since it is difficult for the stacker crane to carry out the warehousing work and the warehousing work at the same time, there is a limit in improving the efficiency of the warehousing and unloading work. The present invention solves the above problems, and an object of the present invention is to provide a three-dimensional storage facility that can be downsized and can improve the efficiency of storage and retrieval work.

[0006]

In order to solve the above problems, the three-dimensional storage equipment according to the present invention is provided with a shelf having a plurality of storage sections formed in the horizontal direction and having a plurality of upper and lower stages, and an elevating device at a plurality of locations on the shelf. Is provided to form a horizontal movement passage extending between the loading / unloading side of the storage section of each stage and the loading / unloading side of the elevating device, and a moving carriage for moving these movement paths is provided,
A plurality of transfer carriages that can be transferred between the lifting device and the moving carriage and between the moving carriage and each of the storage units are provided, and a holding tool for holding and releasing a load is provided to these transfer carriages.

[0007]

According to the above construction, after the load is held on the carrier by the holder, the carrier is moved up and down by the lifting device to the height of the predetermined shelf level. Then, the transport carriage is transferred from the lifting device to the moving carriage, and the moving carriage is moved along the moving passage. As a result, the transport carriage moves horizontally with the moving carriage to the loading / unloading side of the intended storage section. After that, the transport carriage is transferred from the moving carriage into the storage compartment, the holder is opened, and the load held by the transport carriage is lowered into the storage compartment. As a result, the load can be stored in the intended storage unit.

[0008] Further, after the load stored in the storage section is held on the transport carriage by the holder, the transport cart is transferred from the storage section to the moving carriage, and the moving carriage is leveled to the loading / unloading side of the lifting device. To move. After that, the load can be unloaded from the shelf by moving the transport carriage from the moving carriage to the lifting device and moving the lifting device up and down to a certain position (such as the ground).

The above-mentioned warehousing work and warehousing work can be performed at the same time by providing a plurality of elevating devices and transporting carriages and providing a moving carriage for each stage of the shelf. Also, because the vertical movement, horizontal movement, and delivery of the load are performed separately by the lifting device, the moving carriage, and the transport carriage, even when the load is heavy and the shelf is high, a stacker crane or the like can be used. The entire facility can be made smaller than the conventional three-dimensional storage facility.
