DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Conventionally, in a multi-tiered shelf, a plurality of shelves, ie, a front shelf and a rear shelf, are provided before and after in a moving direction of a transfer device for each shelf row in order to increase the number of loads accommodated in the shelf. A so-called double storage type shelf structure has been used. In the shelf structure of this double storage system, when the cargo stored in the rear shelf is unloaded by the stacker crane, the cargo stored in the front shelf is moved to another shelf and then stored in the rear shelf. The unloading of existing cargo was being carried out. Therefore, in the case of the double storage type shelf structure, it is necessary to always provide a replacement shelf to store the load stored in the front shelf, and the total number of shelves cannot be used for storing the load. was there.

[0002] A shelf structure in a conventional automatic warehouse will be described below with reference to FIGS.

In FIGS. 6 and 7, reference numeral 1a denotes a loading / unloading station provided between shelf columns 5a and 5b at the end of each row of shelves 9, and has empty spaces 15 on both sides of the station section 1a.

Reference numeral 4 denotes a shelf supported by beams and shelf columns 5a and 5b, 9 denotes a shelf row, 10 denotes a front shelf provided in each shelf row, 11 denotes a rear shelf, 12 denotes a passage for a transfer device, and 13 denotes a transfer device passage. The transfer device 14 is a pallet receiver.

As described above, in the conventional automatic warehouse, since the shelf 5b is provided on the transfer device passage 12 side of the station 1, the station 1 must be provided between the shelf 5a and 5b. The dead space 15 is formed on both sides of the station.

[0006]

As described above, in the conventional double storage type shelf structure, when unloading the load stored in the rear shelf, the load stored in the front shelf is evacuated. It is necessary to provide the evacuation shelves in the row of shelves, and these evacuation shelves are not always used for storing loads, which causes a reduction in shelving efficiency. Therefore, the present invention solves the above-mentioned conventional problem by providing a shelving shelving unit in a station unit which has not been conventionally used as a dead space in a double storage type shelf. And, as described as a conventional device, since a shelf supporting a hanging shelf is provided on the passage side of the transfer device in the conventional station unit,
The station portion was provided at an intermediate portion between the columns, so that both sides of the station portion had dead spaces.
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention aims to improve the storage efficiency of shelves by changing the installation of shelf columns so as to use the dead space of the station section as shelters.

[0007]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems. In a double-storage type automatic warehouse, a loading / unloading station is provided at the end of each row of shelves on the side of the transfer device passage. And a shelves for evacuation are provided in the section, and a shelf on the side of the transfer device passage is erected on a hanging shelf.

[0008] The present invention has the above structure,
The empty space on both sides of the station, which was not used as a storage space at all, can be used as shelves for evacuation, so that all shelves can be used for storing cargo and the conventional shelf structure Even if it is, it can provide an automatic warehouse that can be repaired at low cost.
