DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional warehouse apparatus capable of storing a large number of loads.

[0002]

2. Description of the Related Art Conventional prior art of a three-dimensional warehouse apparatus for loading and unloading goods to and from a cargo receiving shelf by a stacker apparatus is roughly classified into two types. One of them is that, as disclosed in Japanese Utility Model Laid-Open Publication No. 62-164209, fixed shelves in which a plurality of receiving spaces are arranged in a matrix in the vertical and frontal directions are provided facing each other, A stacker device having a slide fork runs between shelves.

As another one, as disclosed in JP-A-56-28198 and JP-B-55-5525, the load receiving spaces in fixed shelves are arranged in a matrix in the vertical and frontal directions. And a deep receiving space in which two packages can be placed in the depth direction of each shelf, and a slide fork in the stacker device is configured to be a multi-stage telescopic type.

[0004]

According to the former,
Since the depth of the receiving space in the opposed two rows of fixed shelves is shallow, the forward / backward distance of the slide fork in the stacker device with respect to the receiving space is shortened, and there is an advantage that the structure can be simplified. However, since one traveling passage required for traveling of the stacker device is required for two rows of fixed shelves opposed to each other, the ratio of the area of the fixed shelves to the area of the traveling passage becomes small. In other words, the number of effective receiving spaces for a given warehouse site area is reduced, and the area efficiency is low.

On the other hand, according to the latter, although the structure of the slide fork in the stacker device is complicated, the load can be placed in two rows in front and rear on each fixed shelf, so that the area efficiency is increased. However, according to the latter,
In order to remove the luggage placed on the back side of the fixed shelf by the slide fork in the stacker device, it is necessary to remove the luggage on the front side in advance, which increases the time required for loading and unloading the luggage, and reduces work efficiency. There was a problem.

To solve this problem, Japanese Utility Model Application Laid-Open No. 52-8
Japanese Patent Publication No. 382 proposes that a traveling path is formed on the front and back of a fixed shelf having a large depth in which luggage can be placed in two front and rear rows, and luggage on the sides close to each other is taken in and out by a stacker device. However, this is substantially the same as the former configuration. The present invention solves these problems of the prior art, and provides an inexpensive three-dimensional warehouse apparatus which increases the number of effective receiving spaces for a predetermined warehouse site area and does not reduce the work efficiency of loading and unloading. It is intended for.
