Each storage drive device 40 includes a travel drive motor 41 for driving the pallet 14 to travel, and a direction change motor 42 for changing the direction of a rail (not shown) attached to the lower part of the barre 14. , a pallet position sensor 43 for detecting the position of the pallet driven by the travel drive motor 41, and a rail position sensor 44 for detecting the position of the rail driven by the direction change motor 42. Detection signals from these position sensors 43 and 44 are supplied to a control computer 60. The turnout drive device 50 includes a motor (not shown) for rotationally driving the rotary table 13 and a sensor (not shown) for detecting the rotational position of the rotary table 13.

The detection signal of this sensor is also supplied to the control computer 60.

Next, the operation of this embodiment will be explained with reference to FIG. Here, the storage section 12 is partitioned into 2 sections with 3 rows and 9 columns.
It has 7 divided spaces 18 and 4 empty spaces.

It is assumed that each partitioned space is assigned an address (x, y). Here, X indicates column numbers 1 to 9, and these are the front and back directions. Further, y indicates line numbers 1 to 3, which are taken as the left and right direction. Empty spaces are shown blank and pallet spaces are shown gray. Empty spaces are divided space addresses (2, 2), (3゜2), (4
, 2), and (5, 2).

Now, as shown in FIG. 3(a), move the shaded palette at address (1, 2) in the partitioned space (hereinafter referred to as the target palette) to address (9, 2). The operation in this case will be explained.

At this time, the management computer 30 first sends the pallet to address (1, 2) as a command signal (pallet control data).
→ Send data to move to (2, 2) (move forward in the front-rear direction) to the control computer 6° (Figure 3 (b))
. The control computer 60 first detects the running direction of the spaces (1°2) and (2,2) using the rail position sensor 44 according to the pallet control data (1°2)→(2,2) from the management computer 30. do. For example, if the space (it 2) is in the front-rear direction and the space (2, 2) is in the left-right direction, the control computer 30 first changes the direction of the space before the pallet travels. By selecting and turning on the storage switch 81, the control computer 30 connects the storage drive controller 71 and the direction change motor 42, generates a storage speed control signal VCI, and switches on the storage drive controller 71. The controller 71 rotates the direction change motor 42 according to the signal, performs a direction change operation, monitors the rail position sensor 44, and erases the storage speed control signal VC1 when the direction changes from left and right to front and rear. Also, the storage switch 81 is turned off to complete the direction change.

As a result of the above, the directions of spaces (1, 2) and (2, 2) are all forward and backward, so the control computer 30 moves the pallets. First, the storage switch 81 is selected and turned on, and for example, the storage drive controller 72, the travel drive motor 41 of the space (1, 2), and the space (2, 2)
) are connected at the same time, the storage speed control signal VCI is generated, and the storage drive controller 71 is connected simultaneously.
In accordance with the signal, the traveling drive motors 41 of spaces (1, 2) and (2°2) are rotated in the forward direction. As a result, the palette on space (1, 2) is changed to space (
2, 2) and monitors the pallet position sensor 43,
When the pallet moves to space (2, 2), the storage speed control signal VC1 is cleared and the storage switch 81 is
off and finish moving the pallet. As a result, the target palette moves to address (2, 2) (Figure 3 (
C)).

Next, the management computer 30 uses the pallet control data as pallet control data.
Data is sent to move the pallet from address (2,2)-(3°2) and from address (1,1) to (1,2) (FIG. 3(C)). As a result, the target pallet moves by 1 m from address (3, 2), and the pallet at address (1, 1) moves to address (1, 2) (FIG. 3(d)).

Similarly, under the control of the management computer 30, the target pallet is sequentially moved from address (3, 2) to address (4).
,2)→(5,2)→(6,2)−' (7,2)4
Move from (8, 2) to (9, 2) (Fig. 3 (e) to (
j)).

In this way, in this example, the target palette is changed from address (1, 2) to address (9, 2) in eight steps.
can be moved to Therefore, it is possible to take the vehicle out of the warehouse in a short time, and the waiting time at the time of leaving the warehouse can be reduced.

In the above embodiment, the case where there are four empty spaces has been described, but if there are three or more empty spaces, the waiting time at the time of exit can be sufficiently reduced.

Next, a case will be described in which a maintenance person periodically inspects and repairs the storage drive device 40.

First, as shown in FIG. 4, for example, the partition space Na
5, the maintenance staff uses the console and keyboard 100 shown in FIG. 5 to switch the management mode of the management computer 30 from the storage/retrieval mode to the inspection/repair mode, and at the same time, the maintenance staff uses the console and keyboard 100 shown in FIG. 14
For example, to move to partition space Nα8,
Instruct the management computer 30.

In response to this, the management computer 30 sends a switching signal to the control computer 60 to switch to the inspection/repair mode, and blocks requests for storage of all vehicles. Furthermore, the management computer 30 transfers the pallet 14 of the partitioned space Nα5 to partitioned spaces NQ, 8
The drive controllers 71 to 74 and storage drive device 40 provided in the corresponding partitioned spaces in order to move the storage drive device 40 and
A storage switch group 81 arranged between them is controlled.

Next, by the above control, the divided space Nα4. When Nα8 becomes drivable, the maintenance person operates the maintenance operation device 1.
01 is connected to the control computer 60 via the connection terminal board 102.

At this time, section space No. 5. The storage drive device 40 provided at Nα8 will be manually operated.

As shown in Figure M6 and Figure 7, the maintenance operation device 101 has a push button for moving the pallet 14 on which the vehicle 15 is mounted in the forward and reverse directions (back and forth or left and right). A maintenance worker can move the pallet 15 to divided space No. 8 and make divided space No. 5 a vacant space.

After inspection and repair, manually operate the maintenance operation device 101 again to move the pallet 14 to classification space No. 5, and then use the console and keyboard 100 to inspect and change the management mode of the management computer 30. Switch from repair mode to loading/unloading mode and complete the process.

〔Effect of the invention〕
