Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack shelf structure for storing luggage in an automatic warehouse.

[0002]

2. Description of the Related Art When storing a load in a rack by a stacker crane of an automated warehouse, the load is usually placed on a pallet or bucket, or directly loaded from a loading / unloading station to a predetermined storage space by a slide fork of the stacker crane. The pallet, the bucket, or the lower portions on both sides of the load are carried and supported by the rack rack by the expansion and contraction of the slide fork.

[0003]

When the shelf supports support the lower portions of both sides of the pallets or buckets or loads in this way, in the case of pallets (buckets) or loads narrower than the width of the shelf supports on both sides, the rack. It was no longer possible to store items in the same pallet or standardized packages. Therefore, the cross-shaped or skewer-type slide forks can be used to load luggage, and the shelf supports can also be aligned with the slide forks to project inward from both sides so that they do not interfere when going up and down. Although it has been proposed to configure so that it can be stored regardless of the situation, the load placed on the shelf receiver is likely to be laterally displaced, which causes collapse of the load. It wasn't, and the cost had risen.

[0004]

The present invention is configured as follows in order to solve the above problems. That is, in a rack receiver in one space of a rack having a plurality of storage spaces in an automated warehouse, a beam is horizontally laid horizontally in a direction perpendicular to the fork advancing / retreating direction with respect to a support, and a beam is loaded on the beam in the fork advancing / retreating direction. A plurality of sets of shelves for supporting the lower surface are provided, the shelves of the central set of the shelves are set to the lowest, and the shelves of the sets on both sides thereof are sequentially arranged to be higher than the shelves of the inner set. The luggage placed on the shelf receiver is a pair of the shelf receivers which prevent lateral displacement.

[0005]

By using such means, the luggage W
If you want to store the
When the load W is placed on the rack R and conveyed to a desired storage position of the rack R, and the slide fork 2 is extended and then lowered, when the load is small, the load is placed on the inner shelf supports 10a and 10a. Both sides of the lower part of the luggage WS are rack supports 1 on both sides thereof.
Lateral displacement is prevented by 0b and 10b. Then, when the luggage is large, it is placed on the outer shelf supports 10b and 10b so that different types of luggage can be stored.

[0006]

The problems and solutions to be solved by the present invention are as described above, and the structure of the embodiments will be described with reference to the accompanying drawings. 1 is a front view of a stacker crane and a rack, FIG. 2 is a side view showing one storage space of the rack, and FIG.
Is also a plan view and FIG. 4 is a side view showing another embodiment.

To explain the overall construction of the automated warehouse in FIG. 1, a traveling rail 14 is laid in the front-rear direction on the floor F in parallel with the rack R, and an upper guide rail 13 is arranged in parallel with the traveling rail 14 on the ceiling. Installed on the upper guide rail 13
The stacker crane S is arranged between the traveling rail 14 and the traveling rail 14 so as to be able to travel back and forth. The stacker crane S
In the configuration, the masts 12 and 12 are erected in front of and behind the traveling body 8 placed on the traveling rail 14, the operation box 3 is placed on the front portion of the traveling body 8, and the drive box is placed on the rear portion. Is disposed to accommodate the traveling motor and the elevating motor of the elevating table 1 in the drive box, and the elevating table 1 is arranged between the masts 12 so as to be able to move up and down.

Supports 15 and 15 are erected on the front and rear of the lift 1, and guide rollers 9 and 9 are rotatably provided on the outer sides of the supports 15 and 15 to rotatably support the masts 12 and 12. They are arranged on both sides and serve as guides for lifting the lifting platform 1. Then, a slide fork 2 is mounted on the lift base 1 so as to be able to move back and forth.
Is provided.

The rack R is provided with pillars 4, 4, ... Standing in parallel in the front-rear direction on the floor F at appropriate intervals, and the beams 11 are horizontally arranged in the front-rear direction on the pillars 4, 4.
·············
The shelf receiver 10 of the present invention is provided between the left and right beams 11 and 11.
10 ... are fixed so that the luggage W can be loaded. The horizontally arranged beams 11, 11, ... Are provided in a so-called European cantilever type rack, and are different from the type in which the column 4 is directly provided with shelf supports in the left-right direction.

That is, as shown in FIG. 2 and FIG. 3, the shelves 10 are a plurality of sets (two sets in this embodiment) of shelves 1 having different heights.
0a, 10b, ...
It is installed horizontally on the inside, and the inside (center side) shelf receiver 10a.1
0a is the lowest, and the smallest load WS can be placed on it. The height of the shelf support 10a is set so that the slide fork 2 can be inserted between the lower surface of the load W and the upper surface of the beam 11. And, the shelf supports 10a, 10 of the central side set
Outer rack shelves 10b and 10b are provided in parallel on both sides of a, and the height of the outer shelves 10b and 10b is higher than that of the inner shelves 10a and 10a.
I am able to put L. However, in this embodiment, two sets of large and small shelves are provided, but three or more sets may be provided so that the central shelves are lowered and the two sets of shelves are sequentially raised.

As shown in FIG. 4, the shelves 10 'have a stepped shelves 10' on the columns 4 and 4 without the beam 11 being installed horizontally.
It is also possible to install 10 'laterally and store luggage of different sizes, and the shelf support 10' is stepped in step 10a in a side view so that it lowers toward the center side. '・ 10b' ・ 10c 'is composed, and shelf holder 10'
A space is provided between the rack support 10 'and the shelf support 10' so that the slide fork 2 can pass vertically. In this case, the slide fork 2 can be formed in a plate shape, and a horizontal brace 16 is provided on the side opposite to the stacker crane S to reinforce so that the horizontal beam 11 is not provided.

When the luggage W is stored by such a configuration, the luggage W is placed on the lift table 1 of the stacker crane S at the loading / unloading station and is transported to the desired storage position of the rack R. When the slide fork 2 is extended and then lowered, if the load is small, it is placed on the inner shelf supports 10a, 10a, and the lower both sides of the load are horizontally moved by the shelf supports 10b, 10b arranged on both sides. The gap is prevented. And when the luggage is large, the outer shelf support 1
It is mounted on 0b and 10b. Further, when the luggage is taken out from the rack R, the lifting table 1 is moved to the storage space of the luggage to be taken out, the slide fork 2 is inserted between the lower surface of the luggage W and the beam 11, and the slide fork 2 is slightly lifted. It suffices to reduce the size of the stacker and return it to the original position, and then return the stacker crane S to the loading / unloading station. However, when lifting the luggage from the shelf, if you set several rising levels of the slide fork 2 according to the size of the luggage, the rising time can be shortened as compared with the case where the lifting level is set to the maximum luggage. It can be taken out efficiently.

[0013]

Since the present invention is constructed as described above, it has the following effects. In other words, it can be used as it is without changing the shape of the conventional slide fork, and since the shelf supports of several heights are provided, it is possible to store even luggage of different sizes in the same rack. Therefore, it is possible to transfer loads of various sizes and improve versatility. Also, since the rack trays on both sides are higher than the rack trays on the inner side, vibrations due to an earthquake or the operation of the stacker crane are transmitted to the rack, and the luggage slips off the rack tray and falls, or when the slide fork moves in and out, the cargo collapses. It was possible to prevent this, and the rack supports on both sides act as stoppers to prevent the luggage from shifting laterally.
