DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warehouse for supplying and storing long materials such as steel bars, pipes and steel bars. The present invention relates to an automatic warehouse for supply and storage of long materials that can be carried in and out of a warehouse.

[0002]

2. Description of the Related Art The present applicant has previously disclosed in Japanese Patent Laid-Open No. 7-2774.
In Japanese Patent Publication No. 28, a plurality of rows of supports are provided on a floor surface in a warehouse, which removably hold a vertical direction of a pallet capable of individually storing long materials in an oblique posture, and
A long material supply / storage device including a transport mechanism movable above a row of supports and capable of inserting and removing a pallet from a support is disclosed. This long material supply / storage device can simplify the equipment as compared with storage using a conventional stacker crane or the like, and can increase the storage efficiency.

[0003]

However, the above-described long material supply / storage device still has the following problems to be solved. That is, in this long material supply / storage device, the pallet is inserted into and removed from the support from above, so that the warehouse needs a space at least equal to the height of the support and the pallet in an oblique posture. For this reason, it is necessary to increase the height of the warehouse building, which is not preferable in terms of facility costs. In addition, a transport mechanism such as a fork that pulls out and transports a pallet can handle only one pallet for one support. That is, the loading and unloading of the pallet by the transport mechanism is 1
This is an operation of processing individual pallets, and in a facility where a large number of pallets are frequently taken in and out, the operation time becomes long.

[0004] As described above, in the conventional long material supply and storage device in which the pallets in the oblique posture are arranged, the equipment itself can be simplified as compared with the stacker crane, but the warehouse building becomes large and the handling efficiency is limited. There are still problems to be improved.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide an automatic warehouse for supplying and storing long materials that can efficiently store and store long materials with simpler equipment. Aim.
