A shipping yard is provided, and a picking device is provided on the second floor and above.

[0005]

[Function] Incoming goods are sorted by type and stored in a pallet, and the pallet is stored on a steel shelf in a warehouse by a stacker crane.

Then, according to the order from the user, the required pallet is taken out by the stacker crane, and then the required number is picked up from the pallet by the picking device and placed on the temporary receiving stand. Repeat this work to take out the required number of various steel materials for each destination and place them on the temporary pedestal. Then, the bundles are hung on the articles on the temporary receiving stand, and the finished bundles are temporarily placed on the steel shelves in the warehouse by the stacker crane. By repeating the above work, the bundled products for each destination are temporarily placed on the steel shelves in the warehouse. Then, at the time of shipping, the bundle is unloaded and shipped.

In this case, by providing a receiving and shipping yard on the first floor and a picking device on the second and higher floors, it is possible to effectively use the land and prevent the work from becoming crowded.
