Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warehouse for supplying and storing long materials such as shaped steel, pipes, steel bars, etc., and in particular, storing such long materials in a pallet and simplifying 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. That is, in this long material supply and storage device, since the pallet is inserted into and removed from the support from above, the warehouse requires a space equal to or higher than the height of the support and the pallet in an oblique posture. 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.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an automatic warehouse for supplying and storing long materials, which allows efficient storage and storage of long materials with simpler equipment. To aim.

In the width direction orthogonal to the arrangement direction of the racks 10, two pairs of rails 30 are laid across the substantially entire width thereof with parallel intervals in the front and rear directions. And each pair of rails 30
A transverse carriage 14 is attached to each of the carriages so as to traverse freely.

At this time, the distance between the two transverse child carriages 14 is an integral multiple (twice in this embodiment) of the pitch of the upper and lower rack arms 21 and 22 of the rack 10. Accordingly, the two transverse child carriages 14 can traverse over the rail 30 over substantially the entire width of the carriage main body 24 of the vertical carriage carriage 17, and at the same time, each of the carriage longitudinal paths 1
It is possible to move between 1 and the rack 10.

As shown in FIGS. 1 and 2, the carriage main body 31 of each of the transverse carriages 14 has a rectangular shape in a plan view, and the traveling wheels 32 attached to both sides of the carriage body 31 are the rails 3.
It is rotatably supported at 0. In addition, as shown in FIG. 7, the rotating shaft 33 to which the traveling wheels 32 are fixed has a speed reducing mechanism 34.
Drive motor 3 attached to the trolley body 31 via the
It is interlockingly connected to the output shaft of No. 5.

As shown in FIGS. 1, 3, 5, and 7,
A pallet mount 36 having a horizontally long rectangular shape in plan view is mounted at the center of the carriage main body 31 so as to be vertically movable by a lifting device 37a. In the present embodiment, as shown in FIG. 5, the lifting device 37a is attached to the central portion of the truck body 31, and the lifting cylinder 37 whose upper end is connected to the lower portion of the pallet mount 36 and the truck body 31. The pallet mounting base 36 is mounted on both sides and is configured to include a lifting guide 38 that guides the lifting and lowering of the pallet mounting base 36.

Further, as shown in FIGS. 1 to 3 and 7,

The inclined support surface 39 of No. 5 is brought into contact with the lower end of the pallet 13 and is slightly lifted so that the pallet 13
Can be transferred from the rack 10 to the transverse carriage 14. After the transfer, the traverse carrier carriage 14 is traversed from the position in the rack 10 indicated by the alternate long and short dash line in FIG. 5 toward the position in the carriage longitudinal passage 11 indicated by the solid line, and then the longitudinal master carriage 17 is moved. By driving, the transverse carriage 14
The pallet 13 can be carried out to the outside of the automatic warehouse for supplying and storing long materials by moving the pallet 13 along the trolley longitudinal path 11 and then tilting the pallet 13 horizontally by a tilting device (not shown).

Next, the work of loading the pallet 13 will be described. First, the pallet 13 loaded from the outside into the automatic warehouse for supplying and storing long materials is erected from the horizontal state to the inclined state by the tilting device and placed on the traverse carriage 14. Next, the vertical carriage 17 is driven to move the horizontal carriage 14 along the carriage longitudinal path 11 to obtain the desired value.
It is stopped at a position corresponding to the lower rack arms 21 and 22. Next, after the transverse carriage 14 is moved laterally from the position in the carriage longitudinal path 11 indicated by the solid line in FIG. 5 to the position in the rack 10 indicated by the alternate long and short dash line, the lifting device 37a is driven to drive the pallet receiving seat 15 By lowering the lower end of the pallet 13 to abut and support the lower rack arm 22 and the rear surface of the pallet 13 to the upper rack arm 21.
The pallet 13 can be transferred from the transverse carriage 14 to the rack 10 by supporting the pallet 13 on the front surface of the rack 10.
After the transfer, the traverse carrier truck 14 is moved from the position in the rack 10 indicated by the alternate long and short dash line in FIG.
Traverse to the position in 1 and let the next carry-out / carry-in work be performed or wait.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the configurations described in the above embodiments, and is described in the scope of claims. It also includes other embodiments and modifications that are conceivable within the scope of the matters. For example, in the above-described embodiment, the number of pallets supported and stored by each rack arm is two, but it may be one or three or more.
