BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warehouse for storing long materials such as shaped steel, pipes and steel bars, and more particularly to a long material having a transfer device capable of automatically dispensing or storing long materials. It concerns a three-dimensional warehouse.

[0002]

2. Description of the Related Art Conventionally, as a transfer device for such a long material storage warehouse, an outer surface that moves in a direction perpendicular to a plurality of rows of long materials installed on arms provided in a plurality of stages on a plurality of columns A device was used in which a stacker crane that travels was arranged and transferred by this.

For example, in the storage facility as shown in FIG. 5 of Japanese Utility Model Laid-Open No. 60-183708, the fork of a truck (stacker crane) has a structure in which a long material is mounted by overhanging only on one side. When you exit the rack shelf on the opposite side immediately after the storage is completed, return to the turntable once, rotate 180 °, and travel to the rack shelf to exit again to take out the long material. It takes a long time to run and is useless. Also,
When adding rack shelves, long materials are stored in the longitudinal direction, and there is a limit in extending the rack shelves from the factory building in the longitudinal direction. If the number of trucks (stacker cranes) and rack shelves is multiple due to the expansion of rack shelves, a turntable is also required, resulting in enormous equipment costs, and if the loading and unloading cycle time is too long. There was a drawback to say.

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a storage device and a transfer device for storing long materials without using a pallet, and in which storage and delivery are extremely easy.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention is that a plurality of long material storage frames are vertically tilted on an endless storage conveyor, and can be moved up and down on the inlet and outlet sides of the storage conveyor. A plurality of rows of conveyors with lifters are arranged, and in each gap of the rows of conveyors with lifters, a transfer conveyor that drives in a direction orthogonal to the transfer direction of the conveyors is arranged. In the long material storage / conveying device, a payout lifter is provided below the long material storage frame located on the delivery side and in the vicinity of the conveyor with lifter.

[0006]

[Function] First, the conveyor conveys the material from the entrance side equipment (not shown) and stops after conveying to the storage position. At the same time, the storage frame designated for storage is rotated at the storage conveyor by the storage conveyor. Stop at position. Next, the conveyor with lifter is raised and then rotated to insert the material into the storage frame to complete the storage. Next, when the designated storage frame is rotated by the storage conveyor and stopped at the most exit side, the conveyor with lifter rises to a position slightly lower than the upper surface of the storage frame and then waits for the delivery lifter to move up. Then, after dropping the material to the side of the conveyor with lifter, the conveyor rotates to transfer the material to the center and then lowers it to load it on the transfer conveyor. Then, the transfer conveyor rotates and supplies the material to the next step.

EXAMPLES The present invention will be specifically described below with reference to examples. 1 is a front view showing an embodiment of the present invention, FIG.
Is the side view. In the figure, 3 is an endless storage conveyor, which is driven via a sprocket 6. Reference numeral 7 denotes a bearing for the sprocket 7, which is engaged with the frame 8.
A plurality of long material storage frames 2 are attached to wheels 4 on the storage conveyor 3.
Is laid vertically.

Reference numeral 5 is a guide rail for the wheels 4, which is provided in parallel with the storage conveyor 3. Then, the long material storage frame 2 on which the long material 1 is mounted is moved by driving the storage conveyor 3 while riding on the rails 5 via the wheels 4.

Reference numeral 9 denotes a conveyer with a lifter, which communicates with a direct-feeding line 11 for the long material 1 and which conveys the long material 1 to the longest position (outward) side of the storage conveyor 3. It can be raised to a position where it can be placed on the material storage frame 2.
Reference numeral 12 is a transfer conveyor, which is arranged in each of the gaps in the row of conveyors 9 with lifters, and is driven in a direction orthogonal to the transfer direction of the conveyors 9 with lifters or the direct transfer conveyor 11.

Reference numeral 10 denotes a payout lifter, which is located below the long material storage frame 2 located on the most outmost side of the storage conveyor 3 and is raised to the rising level of the lifter-equipped conveyor 9 and placed on the storage frame 2. The long material 1 being pushed up is lifted up and discharged to the conveyor 9 with lifter. The upper surface of the payout lifter 10 is formed with an inclined surface for automatically rolling and dropping a long material (in FIG. 1, the loading / unloading portion of the lifter-equipped conveyor 9 may be formed on the right side). ).

Next, the steps of loading and unloading (storing and paying out) the long material 1 will be described in order. The material 1a transported by the transport conveyor 12 comes to a storage position and stops, and the storage conveyor 3 rotates the designated long material storage frame 2 for storage and stops at the most-entrance side. Let
Next, the conveyor 9 with lifter rises, lifts the material 1a, and stops it at a position where the conveyor upper surface is slightly higher than the upper surface of the storage frame 2 (state of the conveyor 9b), and then the conveyor rotates to rotate the storage frame 2 The material 1a is inserted in. This completes the storage (stocking) of materials.

Disbursement (delivery) of materials (specified materials)
When the storage frame 3 is rotated by the storage conveyor 3 and stopped at the most entrance side, the conveyor with lifter is also raised so that the conveyor upper surface is slightly lower than the storage frame 2 upper surface (conveyor 9a position). Stop).

Next, the lifter 10 rises to lift the material 1, but since the upper part of the lifter is inclined,
The material 1 drops onto the lifter-equipped conveyor 9a, the conveyor 1 is rotated to transfer the material 1 to the center of the conveyor 9a, and then the lifter-equipped conveyor 9a descends to transfer the conveyor 12
The material 1 is transferred onto the top, and the delivery (delivery) to the entrance side or the exit side is completed.

Further, for the material which is directly stored from the inlet side to the outlet side without storing the material 1 in the storage conveyor 3,
The direct transfer conveyor 11 on the entire lower part of the storage conveyor 3 is
It is also possible to receive the material directly and convey it directly to the output equipment.
