Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse for supplying and storing long materials such as shaped steels, pipes, and steel bars, and particularly, to store these long materials in a pallet and simplify the pallet as a unit. The present invention relates to an automated warehouse for supplying and storing long materials that can be loaded into and unloaded from.

[0002]

2. Description of the Related Art The applicant of the present invention has previously filed Japanese Patent Application Laid-Open No. 7-2774.
In JP 28, a plurality of rows of supports for detachably holding a pallet capable of individually storing long materials in an oblique posture in the vertical direction are installed on a floor surface in a warehouse, and
Disclosed is a long material supply and storage device that is movable above a row of supports and that has a transport mechanism that allows a pallet to be inserted into and removed from a support. This long material supply and storage device can simplify the equipment as compared with the conventional storage by a stacker crane or the like, and can increase the storage efficiency.

[0003]

However, the above-described long material supply and storage device still has the following problems to be solved.

Therefore, it is necessary to make the warehouse building taller, which is not preferable in terms of equipment cost. In addition, a transport mechanism such as a fork that transports a pallet by inserting and removing it can handle only one pallet with respect to one support. That is, pallet loading / unloading by the transport mechanism is 1
It becomes an operation to process each piece individually, and the operation time becomes long in a facility where many pallets are frequently put in and taken out.

As described above, in the conventional long material supply and storage device in which the pallets in an oblique posture are arranged, although the equipment itself can be simplified as compared with the stacker crane, the size of the warehouse building and the limit of the handling efficiency are increased. There are still problems to be improved.

An elevating device 49 consisting of a hydraulic cylinder is attached to the center of the carriage main body 23, and a third pallet receiving seat 21 is attached to the tip of the telescopic rod. Therefore, by operating the elevating device 49, the height of the pallet supporting surface of the third pallet receiving seat 21 is set to the first pallet receiving seat 28 of the rack 10 and the vertical parent carriage 19 described later. It can be raised or lowered by a minute distance from the attached second pallet seat 38.

Next, unloading and loading operations of the pallet 15 by the automatic warehouse for supplying and storing long materials having the above-mentioned structure will be described.

First, the unloading work of the pallet 15 will be described. The vertical parent carriage 19 in the carriage longitudinal passage 11 is operated to accurately align the second guide rail 20 thereof with the first guide rail 16 of the rack 10. As shown in FIG. 1, the traverse child carriage 17 is operated by the child carriage traverse multi-stage expansion / contraction device 24 so that both guide rails 20,
Via 16 the carriage traverse 11 into the rack 10. The elevating device 49 is operated to raise the third pallet receiving seat 21 attached to the front end thereof by a minute distance, and until now, it was supported by the first pallet receiving seat 28 of the rack 10 and the upper rack arm 12. The pallet 15 is supported by the third pallet receiving seat 21 and the second pallet receiving frame 22.

As shown in FIG. 1, the child carriage traverse multistage expansion / contraction device 24 is operated to move the traverse child carriage 17 from the rack 10 to the carriage longitudinal path 11. By operating the elevating device 49, the third pallet receiving seat 21 is lowered by a minute distance, and the pallet 15 which has been supported by the third pallet receiving seat 21 and the second pallet receiving frame 22 until now is
It is supported by a second pallet receiving seat 38 and a first pallet receiving frame 40 mounted on the vertical parent carriage 19. After that, the vertical parent carriage 19 is moved along the carriage vertical passage 11 and the pallet 15 is tilted to a horizontal state by a tilting device (not shown) to move the pallet 15 to the outside of the automatic warehouse for supplying and storing long materials. It can be carried out.

Next, the work of loading the pallet 15 will be described. First, the second pallet mounted on the vertical carriage 19 by causing the pallet 15 loaded into the automatic warehouse for supplying and storing long materials from the outside to stand up from the horizontal state to the inclined state by the tilting device. It is supported by the receiving seat 38 and the first pallet receiving frame 40. The vertical parent carriage 19 is actuated to move along the carriage vertical passage 11 and stop at a position corresponding to the desired upper and lower rack arms 12 and 13 to accurately align both guide rails 20 and 16. .

From the lowered position shown in FIG.
7 is operated to raise the third pallet receiving seat 21 attached to the tip thereof by a minute distance,
The pallet 15 supported by the second pallet receiving seat 38 and the first pallet receiving frame 40 is supported by the third pallet receiving seat 21 and the second pallet receiving frame 22. After operating the child carriage traverse multi-stage expansion / contraction device 24 to laterally move the traverse child carriage 17 from the carriage longitudinal path 11 into the rack 10, the elevating device 49 is driven.

1 and the rack 10 are traversed, and the elevating device 49 is operated in the carriage vertical path 11 and the rack 10 to elevate and lower the pallet 15 by a minute distance required for transfer.
Since the loading and unloading work can be performed in the automatic warehouse for supply and storage of No. 4, it is possible to eliminate the conventional upper space for withdrawing the long material 14, and to reduce the height of the warehouse. Therefore, the equipment cost can be reduced.

Further, the traverse child carriage 17 does not require a separate transfer device having a complicated structure, and uses the child carriage traverse multistage expansion / contraction device 24 and both guide rails 16 and 20 to form the carriage longitudinal path 11 Since the rack 10 can be easily moved to and from the rack 10, the rack 10 is mounted on the upper and lower portions of a plurality of rack posts 25 which are vertically provided with a space in the vertical direction.
It is possible to have a simple configuration in which the guide rails 16 are attached while the three are connected in a cantilever shape. Therefore, the rack 10 can be manufactured at extremely low cost without requiring precision in manufacturing the rack 10. In addition, since the child carriage 17 for traverse can be made to enter the rack 10 from the carriage longitudinal passage 11 by a sufficient distance by the cooperation of the child carriage traverse multi-stage expansion / contraction device 24 and both guide rails 16 and 20,
A large number of pallets 15 can be stored in one rack 10 and the effective use of the space in the automatic warehouse for supplying and storing long materials can be enhanced.

Next, a specific configuration of the child carriage traverse multistage expansion / contraction device 24 used in the present embodiment will be described in detail with reference to FIGS. 4 to 8. As shown in FIG. 6 and FIG. 8, the child carriage traverse multi-stage telescopic device 24 substantially includes a fixed frame 41 having a U-shaped cross section fixed to the longitudinal parent carriage 19.
And the first to fourth moving frames 42 to 45 that are stacked on the fixed frame 41 in four steps and that have four U-shaped cross sections that can expand and contract from the vertical parent carriage 19 toward the rack 10. The rotary motor 50 and a moving frame interlocking expansion-contraction mechanism including rack teeth and pinions that convert the rotational force of the rotary motor 50 into the advancing and retracting forces of the moving frames 42 to 45.

That is, as shown in FIGS. 6 and 8, a first pinion 56 is fixed to the output shaft 55 of the rotary motor 50 fixed to the vertical parent carriage 19, and the first pinion 56 is fixed. The first rack teeth 57 attached to the lower surface of the fourth moving frame 45, which is movably arranged in the fixed frame 41, are meshed with 56. The fourth moving frame 45 has a second pinion 5 at a position eccentric from the center.
