Description

Description: TECHNICAL FIELD The present invention relates to a pipe storage facility with a loading / unloading device used as a warehouse in a steel mill, a warehouse of a wholesaler, and the like.

[Conventional technology]

2. Description of the Related Art Conventionally, automatic warehouses are mainly used for storing or storing products that are easily sorted or carried easily by humans, or bulky and heavy materials that are easily transported by a machine, and long and bound products. -Limited to small-diameter pipes (especially the former), a large number of pipes were not tied, and they were not used for storage of long, medium- and small-diameter pipes from which individual pipes had to be taken out one by one.

[Problems to be solved by the invention]

Automated warehouses are considered mainly for improving product storage capacity, product management level, and shortening entry and exit times, and from trucks to warehouses to mainly store lightweight objects that are easy for humans to handle. Conversely, transportation from the warehouse to the truck was not a problem. For this reason, automation of transport between trucks and warehouses has been delayed, and labor-intensive old-fashioned work has been repeated, so even if pallets or forklifts are used, work efficiency is poor and labor is required. However, there is a disadvantage that the waiting time of a truck or the like increases.

On the other hand, storage of long, medium and small-diameter pipes that is not based on an automatic warehouse not only has the same disadvantages as described above outside the warehouse,
The work efficiency is low in the warehouse and labor is required. In addition, there is an inconvenience that it is not suitable for single item management such as taking out a pipe one by one while going around a mountain.

In recent years, there has been a demand for rationalization of logistics even for heavy and large products, and in particular, it is based on the premise that single products can be taken out one by one without using a mountain pass, using an automatic warehouse at a relay base such as a wholesaler. Sorting and storage of the products are becoming necessary.

[Object of the invention]

The present invention has been made to solve the above problems,
Assuming that individual pipes can be taken out one by one without going through a mountain, sorting pipes from trucks or other cargo transporting means and loading them into an automated warehouse, and conversely transporting the pipes from the automated warehouse to the cargo transporting means. An object of the present invention is to automate as much as possible, save labor and shorten the time required for receipt and shipment, and improve storage efficiency.
