Abstract

PURPOSE:To reduce turn-in and turn-out apparatuses, simplify the equipment, and improve its maneuverability in such a way that in an automatic warehouse having the plural number of shelf lane, the turn-in and turn-out sides of the shelf lanes in back-to-back contignation are connected to each other with a mover between the lanes, and movement between the shelf lanes for cargo is made possible. CONSTITUTION:In case where a cargo which has been turned in using a turn-in and turn-out apparatus is warehoused on shelf lane 4 or 5, the cargo is moved onto a mover 15 between the lanes using an automatic stack lane 2, and the mover 15 between the lanes are moved to the side of the shelf lane 5. As to warehousing on the the shelf lanes 6, 7, the automatic stack lane 2 is used as it is. A mover 16 and an automatic stack lane 3 are used for shelf lanes 8, 9. In the case of turn-out, the process should be reversed. Because the number of turn-in and turn-out apparatuses is thus reduced, the equipment is simplified, and the maneuverability can be improved.

Description

[Detailed description of the invention] The present invention relates to the structure of an automated warehouse.

Conventionally, in the case of an automated warehouse where loading and unloading is required on multiple floors, as shown in Fig. 1, a plurality of auto stack cranes (α) are installed so as to run in parallel, and cranes are placed on both sides of each in the running direction. A loading/unloading device (8) is provided between each end of the shelf lane (BL) and a loading/unloading device (8) that allows loads to move through the shutter (d) between each end of the rack lane (BL) and the loading/unloading rack (CL) provided on each floor. There is.

However, the conventional device described above had the following problems.

The same number of loading and unloading devices (g) as the number of rack lanes (b) are required on each floor, and as the number of required floors increases, the equipment cost for the loading and unloading devices (e) increases significantly.

(B) There are many regulations regarding fire prevention zones, etc., and the shutters (
dl increases according to the number of loading and unloading devices (-), and equipment costs increase.

(q) If the selection of the receiving shelf lanes (61) is not made equal, there will be unevenness in the stocking volume of each shelf lane (b), and there is a greater possibility that the dispersion between the shelf lanes (63) at the time of retrieval will increase. .

(Ugami shelf lane (63) If it becomes necessary to move the cargo between shelves lanes (6) and 63, the cargo should be moved to
After unloading the goods to the handling area (c) using
The stack crane at the destination (kM) needs to be loaded into the shelf lane (BL) at the destination, which requires time and effort to move, and the handling area (c) needs to be equipped with a device for transferring the cargo. be.

The present invention was made in view of the above-mentioned conventional problems, and in an automated warehouse having a plurality of shelf lanes, an inter-lane moving device is used to move between shelf lanes arranged back to back and adjacent to each other at the entry/exit side position. This allows for the movement of cargo between shelf lanes, thereby reducing the number of loading and unloading devices installed, simplifying the associated equipment, and improving operability when moving cargo between shelf lanes. That's what I got.

Embodiments of the present invention will be described below with reference to the drawings.

Figures 2 to 4 show an example of the present invention, in which a plurality of auto stack cranes (1) (2 ) Shelving lanes (
In the case of Fig. 3, the loading/unloading device (2) that transfers cargo between the loading and unloading area (6) on each floor through the shutter section 09 is installed at the loading/unloading side end of the rail (toward K). It is installed so that it can be run freely along the line.

In addition, at the lower position of the loading/unloading device (2), the shelf lanes (among the 4th to 9th lanes, between the shelf lanes arranged back to back ((5) and (6) in FIG. 4) ,
and between (7) and (8)), and an inter-lane moving device α0 (g) that can move on the rail α4 is provided.

Next, the effect will be explained.

First, if the cargo received from the storage/unloading device (2) shown in Fig. 3 is stored in the shelf lane (4 or (5) VC,
The auto stack crane (2) was used to transfer the cargo from the loading/unloading device (2) to the inter-lane transfer device (G), and then the inter-lane transfer device (To) was moved to the shelf lane (5) side. Second, the load on the inter-lane moving device (c) is stored in the shelf lane (4) or (5) using the auto stack crane (1).

Move the cargo on the loading/unloading device (2) to the shelf lane (6) or (7)
If it is to be stored on top, a stack crane (2) is used to store it as is.

Move the cargo on the loading/unloading device (2) to the shelf lane (8) or (9).
When storing in the shelf lane (4) or (5), the goods are stored via the inter-lane moving device (to) and the auto stack crane (3) in the same manner as in the case of storing in the shelf lane (4) or (5). Also, when leaving the warehouse, perform the operations in reverse to the above.

As mentioned above, by providing the inter-lane moving devices (c) and (g), the number of installed loading/unloading devices (6) can be significantly reduced.
D. By cyclically controlling the auto stack cranes (1), (2), and (3), warehousing or unloading can be performed equally on each lane. In addition, by being able to reduce the number of storage entry/exit devices @ as described above, in warehouse facilities that require fire protection compartments, it is possible to reduce the number of shutters Qη or doors installed for the fire protection compartments compared to before. It is possible to simplify equipment and increase the degree of fire protection.

Furthermore, even when there is no need for fireproof divisions, the work required to remove holes from partition walls can be reduced. Furthermore, in the above, even when moving cargo between shelf lanes, it can be easily done without using the loading/unloading device@ from the inter-lane moving device α0 country.

In the above embodiment, the number of auto stack cranes is 3, the inter-lane moving device is 1 stage, and the number of loading/unloading devices is 1 per floor. However, the number of installed cranes can be changed in various ways. For example, lane-to-lane moving devices may be installed on multiple floors, or loading/unloading devices may be installed on one floor.
Although a plurality of units may be provided on each floor, and although the illustration shows a case in which both the loading and unloading device and the moving unit between stores are based on carts, other systems (for example, a conveyor, etc.) may also be used. It goes without saying that various changes may be made within the scope of the invention without departing from the gist of the invention.

! According to the automatic warehouse system of the present invention described above, the following excellent effects can be achieved.

to.

(1) Even if the number of floors where warehousing or retrieval is required increases, even if each floor does not have the same number of warehousing or retrieval devices as the number of shelf lanes, it will still be possible to access the warehouse or from the gold side lane. Therefore, the overall configuration of the device can be simplified and equipment costs can be significantly reduced.

(iii) It is possible to evenly stock a plurality of shelf lanes using a single loading/unloading device, and it is possible to easily prevent variations in stocking between shelf lanes.

(iii) Stored loads can be easily moved between shelf lanes using existing auto stack cranes.

(1v) If a fireproof compartment or the like is required, the number of shutters, doors, etc. installed can be reduced by reducing the number of entry/exit devices, and equipment costs can be reduced.
