(c) As a result of the article input to the container 40 in the above (b), when it is calculated by calculation that the front case 2 of each frontage 21 becomes empty by taking out the article, it depends on whether or not it is actually empty. Determine normal and abnormal distribution of goods. That is, when it is calculated by calculation that the case 2 at the head of each frontage 21 is emptied by taking out an article, the remaining number 0 is displayed on the removal quantity / remaining number display 24 of the distribution instruction device 22 of the frontage 21. The operator who sees this display confirms that the first case 2 is actually empty and determines that distribution is normal on the condition that the completion button 25 is turned on. On the other hand, the operator who sees the display of the above-mentioned removal quantity / remaining number display 24 of the remaining number 0 confirms that the top case 2 is not actually empty (under picking) and the removal abnormality button 26 The distribution abnormality is determined on the condition that is turned on, and this abnormality is taken out and displayed by blinking of the quantity / remaining number display 24.
[0012]
(d) When the stock quantity of the case 2 at the head of each frontage 21 is displayed on the taken-out quantity / remaining number display 24 as a result of the article input into the container 40 in the above (b), the operator who has seen this display Even if the take-out error button 26 is turned on after confirming that the actual remaining number of the case 2 is not equal to the display number (excess picking), the distribution abnormality is determined, and this abnormality is taken out and the remaining quantity indicator Displayed by blinking 24.
[0013]
(e) The operator who is informed of the distribution abnormality by the blinking of the taken-out quantity / remaining number display 24 in (c) and (d) above removes the front case 2 of the frontage 21 from the frontage 21 and stores the passage stock. When the completion button 25 is turned on, the stock quantity of the frontage 21 is updated, and the remaining quantity of picking quantity from the frontage 21 to the container 40 to be loaded is also taken out as the quantity to be taken out of the distribution instruction device 22 of the frontage 21. The number is displayed on the remaining number display 24, and the operator picks up the case 2 from the case 2 which is the new head of the frontage 21.
[0014]
(f) When a distribution abnormality is determined according to the above (c) and (d), one item containing articles taken out from the case 2 after the previous determination of normal distribution of articles until the current abnormality determination or A plurality of containers 40 are to be inspected as picking error candidate containers. Then, a picking error candidate container list (container number and picking quantity) is issued, and a forced shipping from the storage area in the lower process of the picking error candidate container to the inspection area is instructed. In the inspection area, inspection based on the picking error candidate container list is executed, and the quantity of input articles is corrected.
[0015]
FIG. 3 shows the No. 3 by the control device 27 when the distribution is normal in the above (a), (b), and (c). 1 container (6 picks), No. The procedure for distributing articles to two containers (6 picks) is shown. That is, from the top case 2 of the frontage 21 (10 full), no. Put six articles into one container and add the remaining four articles in case 2 2 When the container 2 is put in the container and the distribution is judged normal when the case 2 becomes empty, the case No. 2 is newly changed from the case 2 (10 full) to the top. This is an example in which two more articles are put into two containers and picking is finished.
[0016]
FIG. 4 shows an article distribution procedure by the control device 27 when the distribution is abnormal as described above in (c) to (f). That is, the picking quantity / remaining number display 24 displays the remaining number 0 even though there are still two items in the front case 2 of the frontage 21 and the picking quantity / remaining number display 24 displays This is an example of over picking in which the number of stocks in case 2 is 5 but there are actually only 4.
