Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional automatic warehouse for storing thin and long materials (sheet materials) such as steel plates for automobiles without using pallets.

[0002]

2. Description of the Related Art Conventionally, when a sheet material is stored in a three-dimensional automatic warehouse, since the sheet material is thin and long, the sheet material may be dripping or indented.

[0003]

In the case of a three-dimensional automatic warehouse using steel pallets, more pallets than the number of shelves are required, and manufacturing costs are high. In addition, it is necessary to load and unload empty pallets, and the cycle time of the stacker crane becomes stricter accordingly.Therefore, it is necessary to increase the required number of units and the capacity of motors, etc. Machine specifications. In addition, it is necessary to have a stock place for empty pallets, etc., and it is necessary to consider a large space in terms of layout.

However, in the conventional type steel shelves and stacker cranes (transfer system using slide forks), there is concern that the shelves may be bent or damaged due to surface pressure, or may be dropped, or the stacker crane may be damaged due to bending or surface pressure. Therefore, transfer without pallets (palletless) was impossible. An object of the present invention is to provide a three-dimensional automatic warehouse that does not use pallets (palletless), which can solve the above problems.

[0005]

According to another aspect of the present invention, there is provided a three-dimensional automatic warehouse comprising a steel shelf and a stacker crane. And a plurality of supporting members are provided on the slide fork of the stacker crane in a comb-tooth shape corresponding to the comb-tooth-like receiving beam of the above-mentioned shelf. It is what

[0006]

In the steel shelf, since the plurality of receiving beams are projected in the shape of comb teeth, the surface pressure acting on the sheet material can be reduced, and the sagging of the sheet material can be minimized. ..

On the other hand, also in the stacker crane, since the slide fork is provided with the plurality of supporting members in a comb-like shape, the surface pressure acting on the sheet material can be reduced as in the case of the receiving beam of the shelf. The sagging of the sheet material can be suppressed to a minimum.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in the case of being incorporated in a press line as shown in FIG. A plurality of steel shelves 10 are provided on both sides of the stacker crane 15. Details of the steel shelf 10 and the slide fork portion of the stacker crane 15 are shown in FIG.

The steel shelf 10 is constituted by a plurality of receiving beams 12 protruding in a comb-like shape at a narrow pitch from the beam 11 on the opposite side of the stacker crane 15 toward the stacker crane. The cross section of the receiving beam 12 is T-shaped, and a cushioning material 13 such as urethane rubber is attached to the upper surface thereof so that the sheet material S is not damaged.

On the other hand, on the slide fork 16 of the stacker crane 15, a common plate 18 in which a plurality of supporting members 17 are provided in a comb-teeth shape corresponding to the comb-teeth receiving beam 12 of the above-mentioned shelf is attached. .. The height of the support member 17 is larger than the height of the receiving beam 12.

Then, the slide fork 16 on which the sheet material S is placed is advanced toward the steel shelf 10 and then lowered, whereby the sheet material S is moved to the steel shelf 10 as shown in FIG. Reprint. Further, the sheet material S on the steel shelf 10 can be transferred to the stacker crane side by the opposite operation.

Next, the example of FIG. 2 is a blanking press A.
And the tandem press B, a three-dimensional automatic warehouse is incorporated, and the sheet material can be transported without using a pallet.

The sheet material from the blanking press A is placed on the pallet truck 20. As shown in FIG. 3 (a), the piler truck 20 is constructed by vertically arranging a support member 22 having a high height in a comb shape on a truck body 21. The transfer device 25 is a device that transfers the sheet material from the piler truck 20 to the stacker crane 15.

The transfer device 25 is shown in FIG.
As shown in FIG. 5, the main body 26 can run along the girder 27. Then, on the main body 26, there is provided a support base 28 having receiving beams projecting like a comb like the steel shelf,
It is provided so that it can be raised and lowered and can be turned.

As shown in FIG. 3 (b), the trolley 30 has a trolley body 31 with receiving beams 32 protruding like comb teeth like the steel shelves. The sheet material placed on the carriage 30 is fed to the tandem press B by the sheet feeder C.

Further, as shown in FIG. 3C, the transfer device 25 receives the sheet material from the steel shelf 10 and transfers it to the unmanned transport carriage 35. Then, it is conveyed to a transfer press (not shown) that is separately installed.

[0017]

As described above, according to the present invention, since the steel pallet is not required, the pallet manufacturing cost is low, and there is no fear that the sheet material is bent or damaged due to the surface pressure or dropped. , Reliable transfer is possible.
