Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a lifter beam for storing or unloading material in a storage shelf of a three-dimensional shelf.
The present invention relates to a material storage device that is provided with a supply material conveying device and a residual material conveying device to supply a material to a processing line and carry out a residual material from the processing line.

[0002]

2. Description of the Related Art A loading / unloading device for loading and unloading materials into and from each of the above-mentioned storage shelves of a three-dimensional shelf having storage shelves for appropriately accommodating materials such as rods in a plurality of stages has an automated processing line. As a result, it plays an extremely important role. Therefore, there are many patent applications relating to the carry-in / carry-out device, and for example, the carriage having the roll ganig supporting the material described in JP-A-58-78902 moves up and down to carry the material into and out of the storage rack. The composition is known.

Further, it is known that two conveyors described in DE 3817745 are formed in an L shape, a plurality of supporting claws are provided on the conveyors, and materials are carried in and out of a storage rack by the movement of the supporting claws.

Further, there is known a structure in which a material is carried in and out of a storage rack by a parallel link system described in JP-A-62-255301.

[0005]

In any of the above-mentioned conventional material storage devices, the number of treatments of the residual material and the next material is one each, and the residual material after processing is No matter how speedily and reliably the switching is carried out, the processing will be interrupted unless the removal of the remaining material and the supply of the next material are carried out by the separate device after the completion of processing one by one each time. This means that another device must move as fast as that, and a large-scale unloading and feeding device (crane device) cannot catch up with the processing speed like a three-dimensional system.

[0006] For example, in general steel cutting (particularly special steel), the number of cuts per piece is 1.8 on average, and even if the material is supplied according to the processing speed, the processing is completed immediately. However, it will have to be carried out as the remaining material. If the remaining material is carried out by a crane and returned to a predetermined place, then the material for the next material is taken out and supplied, if the processing time is longer than the above processing time, the processing will be interrupted. Especially when using a stacker crane in a three-dimensional system, there is a problem that this possibility is high.

The object of the present invention is to improve the above-mentioned problems, in addition to a device for returning the remaining material and carrying out the next material,
There is a possibility that processing will be interrupted if a separate supply material conveying device and residual material conveying device are provided to process multiple supply materials or residual materials, and the operation of returning the residual material and carrying out the next material will not catch up with the processing. The object is to provide a material storage device in which

[0008]

Configured storage device.

Further, according to the present invention, the supply material conveying device is a lifter which is movable in the Y-axis and Z-axis directions for supplying the material to the processing line, and the residual material conveying device removes the residual material from the processing line. The lifter is configured to be movable in the Y-axis and Z-axis directions to be carried out.

Further, according to the present invention, the residual material conveying device includes a conveyer for supplying the material to the processing line by the supply material conveying device and a lifter which is movable in the Z-axis direction directly below the processing line. Y-axis, Z that carries the remaining material from the line
The lifter is movable in the axial direction.

Still further, according to the present invention, the supply material conveying device is a conveyor for supplying the material to the processing line, and the residual material conveying device is a conveyor for discharging the residual material from the processing line. Is.

[0012]

By adopting the material storage device of the present invention, the desired material is carried out by the lifter arm of the lifter beam from the storage shelves provided in a plurality of stages on the three-dimensional shelf and placed on the lifter provided in the supply material conveying device. To do. The material placed on the lifter is transferred to the feed yard by moving the lifter in the Y-axis direction, and a plurality of materials are stocked. The stocked material can be carried out to the processing line by the lifter regardless of the movement of the lifter beam.

The residual material remaining after processing is taken out from the processing line by the lifter of the residual material conveying device and moved in the Y-axis direction to be stocked in the residual material yard, or
It is returned to the storage shelf again. When returning to the storage shelf, remove the remaining material on the lifter with the lifter arm of the lifter beam,
