Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to shaped steel, pipes, steel bars,
The present invention relates to a transfer device in a storage warehouse for long materials such as, and particularly in a three-dimensional warehouse for long materials that can be automatically dispensed or stored.

[0002]

2. Description of the Related Art Conventionally, as a transfer device in a storage device for such a long material, it moves in a direction perpendicular to a plurality of rows of long materials placed on arms provided in a plurality of stages on a plurality of columns. A device is used in which a stacker crane traveling on the outer surface is 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 12 of a truck (stacker crane) has a structure in which a long material is mounted by overhanging only on one side. Therefore, when leaving the rack shelf on the opposite side immediately after the storage is completed, once it returns to the turntable and rotates 180 °, it also travels to the rack shelf to take out and takes out the long material. It takes a long time and is useless.

Further, when adding rack shelves, long materials are stored in the longitudinal direction, and there is a limit in extending the rack shelves in the longitudinal direction from the factory building, and in the direction perpendicular to the long materials. When adding more rack racks,
When the number of trolleys (stacker cranes) and rack shelves is multiple, a turntable is also required, resulting in a large equipment cost, and there is a drawback that the time cycle of loading and unloading takes too long.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is a three-dimensional warehouse in which long materials are stored without a pallet, and can be loaded and unloaded very efficiently and transported. It is an object to provide a device that can be transferred to equipment such as a table.

[0006]

According to the apparatus for transporting a long material of the present invention, a transfer platform is provided on a carrier for transporting a long material so as to be vertically movable via a lifter, and an appropriate interval is provided on the transfer platform. A plurality of forks are arranged at a predetermined distance, and the forks are formed so as to be vertically movable by an elevating device and horizontally movable in the direction of the material receiving member of the long material storage warehouse, and on the transfer table. A transfer conveyor is arranged between the fork rows, and the transfer conveyor is formed so as to be horizontally movable in a direction orthogonal to the moving direction of the forks.

[0007]

First, the carrier 4 loads only the material 1 loaded on the receiving table 10 by a crane or the like from the input side equipment, but at this time, the vehicle 4 stops before the receiving table 10 and is placed on the vehicle. After the stacking section of No.1 has risen, it advances to the side of the receiving table, and after it has entered the lower side of the material, the lifter 5 ascends and lifts the material 1,
The material is loaded on the dolly as the fork 7 moves backward and descends.

[0008] Next, the truck stops after traveling to the designated rack and stores the material. First, the lifter 5 stops the loading section at a position slightly higher than the material receiving height, and the fork 7 advances to load the material. The part is stopped at the top of the material receiver 3. Next, the loading section is lowered by the lifter 5 to load the material 1 on the material receiver. The lifter 5 is stopped when the loading section is slightly lowered from the lower surface of the material to make a gap, and after the fork 7 is retracted, the lifter 5 is moved. The material is stored in the rack when the is lowered.

For the delivery, the material is received in the reverse procedure of loading into the rack, and the truck 4 stops after traveling to the delivery table 11, and the conveyor 8 on the truck and the conveyor of the delivery table are interlocked to each other. Material is transported to the side equipment.

Embodiments will be specifically described below with reference to embodiments of the present invention. 1 is a front view showing an embodiment of the present invention, FIG.
3 is a side view, FIG. 3 shows that the lifter of the conveying device is viewed from the side, and the material is lifted up to the height at which the material is loaded and unloaded. FIG. 4 is a view of the conveying device from the front of FIG. It shows the time when the fork advances to the material receiver and loads the material.

A is an apparatus for conveying a long material according to the present invention,
The configuration will be described. 4 is a carrier truck, 9 is a guide rail for the carrier truck, and on the carrier truck 4,
A transfer table is vertically movably mounted on the lifter 5. On the transfer table, a plurality of forks 7 are provided on the long member 1.
Are arranged at appropriate intervals along the longitudinal direction of the. The head shape of the fork 7 is formed in a V shape so that the long material can be easily transferred. The fork 7 is formed to be vertically movable via a fork lifting device 6 of, for example, an air pressure type. Further, as shown in FIG. 4, the material receiving member 3 of the long material storage warehouse is placed on the fork lifting device 6.
It is formed so as to be horizontally movable in the direction (the driving device is not shown).

Next, a conveyor 8 is arranged between the rows of the forks 7. This conveyor 8
Is formed to be movable in a direction orthogonal to the moving direction of the fork 7. Reference numeral 2 denotes a pedestal that constitutes a long material storage warehouse, and 10 denotes a storage table that is temporarily placed when the long material 1 is stored.

Next, the steps of loading and unloading the material 1 will be described in order. Material 1 on the receiving stand 10 with an overhead crane
When the transport device A travels to the receiving table side and is stopped at the material loading position when the fork 7 is loaded, the fork 7 advances to enter the lower part of the material 1 and then the fork lifting device 6 moves up to lift the material 1. When the fork 7 is lifted and the fork 7 is retracted, the loading of the material 1 on the transport device A is completed, and the warehousing operation can be performed.

The loading of the material 1 is stopped after the carrier A, that is, the carrier 4 has traveled to the designated rack, and after the lifter 5 on the carrier has moved up to the material receiving member 3 into which the fork 7 should be placed. After moving forward and stopping at the upper part of the material receiving member 3, if the lifter 5 descends and the fork 7 retracts, the material 1 is completely loaded on the material receiving member 3, and the lifter 5
When is lowered to the lower limit, the storage of the material 1 is completed.

When the material 1 is unloaded, the carrier A travels to the designated rack, the material 1 is loaded on the carrier A in the reverse procedure of the material 1 loading, and after traveling to the exit side transport table 11,
The conveyor of the conveying device A and the delivery table 11 are interlocked to deliver the material 1 to the delivery facility (not shown), and the delivery of the material 1 is completed.

[0016]

As described above, according to the present invention, since the long material itself is stored, a pallet is not necessary, and the loading and unloading can be performed very efficiently, and the transport table can be used. Also in the supply to the next process by such as, the long material can be transferred and stored unattended without any waiting time, and the operation rate can be improved.
