Storing whether the article is put into only a single container 8 or divided into a plurality of containers 8 (step-2), and then when a touch signal of the “start” switch is input from the touch panel 27 (Step-3) A picking data request signal including the unique number of the moving vehicle assigned to the picking work carriage 1 is output to the control computer 31 via the wireless communication devices 28, 7 (Step-4).

  When the picking data assigned via the wireless communication devices 7 and 28 is input from the control computer 31 in response to the picking data request signal (step-5), the picking data is stored (step-6). In Step-2, it is checked whether or not "Splitting into multiple containers 8" is stored (Step-7). When "Splitting into multiple containers 8" is stored, picking is performed. The data is converted so that one item picked at a time can be divided and loaded (stored) into a plurality of containers 8 at the same time, and stored as new picking data (step-8).

That is, the picking data formed in one store-item item (-pick quantity) is collected into a plurality of "store-pick quantity" for each item. The converted new picking data is
1 item-"1 store-picking quantity"-"1 store-picking quantity"-"1 store-picking quantity" ...
The data of shelf number N of each item is added, and the new picking data is
“Item Item— {Zone Number—Passage Number M—Shelf Number N—Store Code—Article Name—Picking Quantity} — {Zone Number—Passage Number M—Shelf Number N—Store Code—Article Name—Picking Quantity} -{Zone number-Passage number M-Shelf number N-Store code-Item name-Picking quantity} ...
It becomes.

Subsequently, a store of picking data is allocated to each container 8 (step-9).
Hereinafter, picking data of articles close to the picking start position Y, that is, picking data having a smaller zone number, passage number, and shelf number, are sequentially extracted from the stored picking data (including the case of new picking data). The

  The picking data of the (first) article is taken out (step -10), and it is confirmed from which store code of the picking data to which container 8 the picked article is put (step-11), and this container 8 position is included. As shown in FIG. 4, the picking data screen is displayed on the liquid crystal display 26 (step -12), and the quantity of articles to be input to the digital display 25a of the storage display 25 of the container 8 to be input is displayed.

In the case of new picking data, “container position-input quantity” data of the container 8 to which a plurality of stores of picking data are assigned is displayed on the liquid crystal display 26 of the terminal 21.

  Subsequently, the picking display data composed of the picking data shelf number N (the number unique to the article storage unit 5 of the storage shelf 3) and the picking quantity is formed (step -14), and the picking display data is converted into the wireless communication device 7. To the digital controller 33 (step -15). In the case of new picking data, the picking quantity of each store is added to obtain the picking quantity of the picking display data.

  Next, whether the operation signal of the display / completion button 25b of the storage indicator 25 of all (including a single case) container 8 into which the article is to be input is input (step -16), or “end” is made by the touch panel 27. When the touch signal is input (step-17), it is determined that the picking by the current picking data has been completed (step-18).

  Then, the quantity displayed on the digital display 25a of the storage display 25 of the container 8 to be loaded is turned off, the lamp of the display / completion button 25b is turned off (step -19), and then the LED 23 of the LED group 24 on the front side is turned off. When the LED group 24 on the front side is turned off one by one with time, the LEDs 23 of the LED group 24 on the outer side of the side are sequentially turned off one by one with time (Step-20).

Then, it is confirmed whether or not the picking operation with all the picking data has been completed (step-21). If confirmed, “all end” is displayed on the liquid crystal display 26 on the picking data screen (step-22), and the processing is completed. When the picking data remains, the process returns to Step-10, the next picking data is taken out, and the operation based on the picking data is started.
