And the motor drive unit 57 outputs the speed signal n to the inverter 54
And the motor 53 is driven to move the movable shelf 4 to the right (step-49). Subsequently, the stop lamp 25 is turned off (step -50), and the start lamp 24 is turned on (step -5).
1), end. If the approach detection signal c is input in step -48, the right row completion flag _RR is set (R _R = 1) (step -52), and the right row execution flag R is reset (R = 0) (step-53), and step-6 is executed.

A specific standard (one passage) operation of the movable shelf 4 having the above configuration will be described for a case where a passage is provided on the right side of the intermediate rack 4B in the arrangement of FIG. In the intermediate rack 4B, when the start-up Pb21 is pressed or the standard is selected by the key switch 32 on the centralized operation panel 31,
When the path Pb33 is selected and the activation Pb34 is operated, FIG.
In the steps -18 to 21, the left row instruction is output to the left rack 4A and the right row instruction is output to the intermediate rack 4C. Left rack 4
A outputs a completion signal to the middle rack 4B on the right side because the approach detector 12A is on as in step -38, and the middle rack 4B outputs the left rack 4A as shown in steps -37, 38, 42 and 43. Since the completion signal is input and the approach signal is input, the left rack completion is output to the right intermediate rack 4C, and the left rack 4A and the intermediate rack 4B are stopped and do not move.
Further, the intermediate rack 4C transmits a right-hand instruction to the right intermediate rack 4D as in steps -6 to 8 in FIG. 10, and subsequently, the intermediate rack 4D also transmits a right-hand instruction to the right right rack 4E. The right rack 4E outputs the right row completion to the left intermediate rack 4D because the output signal c of the approach detector 11 is on as shown in steps -48 and 52 in FIG. As shown in steps -47 to 51, the middle rack 4D has completed the execution of the right rack 4E, but moves to the right because the approach detector 11 is not turned on. Further, since the completion signal has not been input to the intermediate rack 4C in step -47, the intermediate rack 4C moves to the right side almost simultaneously regardless of the state of the approach detector 11. When the approach detector 11 is turned on, the middle rack 4D outputs a rightward completion signal to the left intermediate rack 4C and stops, and the intermediate rack 4C also stops.
Turns on and stops. The intermediate racks 4C and 4D move to the right, and a passage is formed on the right side of the intermediate rack 4B.

Next, a specific operation for dispersing the movable shelf 4 will be described with reference to FIG. In the centralized control panel 31, a multi-passage is selected by the key switch 32, and a passage Pb, a passage Pb, a passage Pb
When 33 is selected and the activation Pb 34 is operated, a right row instruction is output to the left rack 4A in steps -17 to 22 in FIG. 7, and the left rack 4A is turned on the right side as shown in steps -6 to 8 in FIG. The rightward instruction is transmitted to the intermediate rack 4B, and subsequently, the rightward instruction is transmitted to the intermediate racks 4C, 4D, and 4E. The right rack 4E outputs the right row completion to the left intermediate rack 4D because the output signal c of the approach detector 11 is on as shown in steps -48 and 52 in FIG. As shown in steps -47 to 51, the middle rack 4D has completed the execution of the right rack 4E, but moves to the right because the approach detector 11 is not turned on. Intermediate rack 4C,
4B and 4A do not input the completion signal in step -47, so they move to the right almost at the same time regardless of the state of the proximity detector 11. Then, when the approach detector 11 is turned on, the intermediate rack 4D outputs a rightward completion signal to the left intermediate rack 4C and stops, and the intermediate racks 4C, 4B, and 4A similarly stop when the approach detector 11 is turned on. As shown in FIG. 16 (b), all the movable shelves 4 converge to the right.

In the centralized operation panel 31, the timer value t (r) of each movable shelf 4 is calculated according to the selected passage at step-21 in FIG. In -23 to 27, the divergence instruction SP and each timer value t (r) are output. In each movable shelf 4, FIG.
In steps -25 to 29, the timer value T is set, and as shown in steps -36, 44 to 46, and 39 to 41 in FIG. And when it reaches the timer set value T, it stops, so
As shown in FIG. 16C, a passage is formed.

Thus, by setting and starting the multi-passage,
The movable shelf 4 is forcibly moved to the right once, and the moving time (timer time) of each movable shelf 4 is set according to the selection of the plurality of passages Pb33, and the moving time is transmitted to each movable shelf 4 together with the spreading instruction signal. By moving each movable shelf 4 to the left by the movement time, the position of each movable shelf 4 according to the set movement time can be determined, and a plurality of passages can be provided. Due to the formation of the multi-passage, it is possible to perform the loading / unloading work on the plurality of fixed shelves 1 and 2 and the movable shelf 4 at the same time, thereby improving the working efficiency. Further, as in the related art, one passage can be formed with standard settings.

In the present embodiment, the movable shelf 4 is once moved to the right and then left and spread by the timer time. However, the movable shelf 4 is once moved to the left and moved right by the timer time. It may be.

As described above, according to the present invention, the moving time of each movable shelf is automatically set by selecting a plurality of passage positions,
After the movable shelf is forced to move leftward (rightward) once, the travel time is transmitted to each movable shelf, and the movable shelf is moved rightward (leftward) by the input travel time, thereby arbitrarily forming a plurality of passages. Can move in and out of the shelves simultaneously in a plurality of aisles, and can improve the work efficiency as compared with the conventional mobile shelf equipment in which only one aisle can be formed between movable shelves or between fixed shelves and movable shelves. You can further select multiple passages positions
Is performed by batch operation of the switches on the central control panel.
Thereby, workability can be improved .
