Description of the Related Art Temporary storage of long products such as steel products such as steel pipes and steel materials and wood is generally carried out in the open storage, flat storage in a warehouse, or in a three-dimensional automatic warehouse. It is performed by storage or the like. Of these, three-dimensional automatic warehouses require a huge amount of capital investment, so in the warehousing industry and distribution field, they are generally rarely installed, and can be mainly carried out by open storage or flat storage in the warehouse. Many. When long objects are stacked in a plurality of stages by such a method, steel frames are installed at predetermined intervals to prevent collapse of the load, and the long objects are loaded in the steel frames.

[0003]

However, when long objects are laid flat in a warehouse, there is a problem that the storage capacity per site is small. In addition, when a plurality of long objects are stacked in a steel frame, the products are liable to be damaged due to contact between the long objects. It is necessary to interpose an intervening object such as a rod or a waste wire, which requires materials and labor, and there is a problem that a sling operation for lifting by a crane or the like is difficult and involves danger. The use of a three-dimensional automatic warehouse solves the above-mentioned problems, but requires a large amount of capital investment for installation thereof, and also has a problem that power costs and running costs increase.

[0004] Accordingly, an object of the present invention is to solve the above-mentioned problems and eliminate the necessity of huge facility costs and running costs as in a conventional three-dimensional automatic warehouse. Another object of the present invention is to provide a storage device for a long object that can be safely and easily performed without causing damage to the long object due to contact or the like, and that has a high storage efficiency per site area.

In the initial state in which the shelf arm is not placed, the lowermost shelf arm is at an obliquely upward angle, and all of the other shelf arms are in a vertically upward state, and are elongated on the shelf arm. Each time an object is loaded, the upper shelf arm is displaced from a vertically upward direction to an obliquely upward angle.

[0006]

According to the apparatus of the present invention, a plurality of shelf arms pivotally mounted on a support column can be rotated from a vertically upward direction to a horizontal direction by a crank arm and a connecting rod. Each time a long object is placed thereon, the upper shelf arm is displaced from a vertical upward direction to an obliquely upward angle so that the next long object can be placed. Therefore, the long objects can be efficiently stored without causing any damage or the like on the plurality of shelves in sequence without contacting each other.
