The storage container transfer conveyor controller 52 controls the drive of the storage container transfer conveyor 13 by the start instruction and the stop instruction output from the control controller 50.

Next, the storage of the storage container 90 in the automated warehouse 22 will be described.
In the article storage facility 20, the storage container 90 is stored in the automated warehouse 22 at the receiving place 21. In the article storage facility 20, the number of articles to be stored in the automated warehouse 22 and the number of orders for articles to be shipped from the automated warehouse 22 are predetermined, and the total number of storage shelves 23 of the automated warehouse 22 ( The storage container 90 is stored in the automated warehouse 22 according to the number of goods stored in the automated warehouse 22 and the number of ordered goods from the customer, up to the number of stored containers 90 that can be stored in the automated warehouse 22). Here, in the sorting facility 10, when the same articles are allocated in the sorting areas 11 and 12 during the sorting work of the articles in the sorting areas 11 and 12, the storage container 90 containing the articles is specified. The same article is distributed and stored in a plurality of storage containers 90 so as not to stay in the sorting areas 11 and 12, and is stored in the automated warehouse 22. When the goods are discharged from the automated warehouse 22, the plurality of storage containers 90 are sorted. It is distributed and transported to areas 11 and 12. Therefore, the conveyor controller 35 calculates the number of storage containers 90 for sorting and storing the same goods according to the number of orders for goods to be delivered from the automated warehouse 22, and sorts the goods into the calculated number of storage containers 90. And store it in the automated warehouse 22. Specifically, the number of storage containers 90 is calculated as follows and stored in the automated warehouse 22.

When the goods arrive at the arrival place 21, the conveyor controller 35 calculates the physical number of storage containers 90 required to store the received goods in the storage container 90 and store the goods in the automated warehouse 22. .. That is, the number of storage containers 90 required to store all the received articles of the same type is calculated. Specifically, the conveyor controller 35 includes the number of goods received in the receiving place 21, that is, the number of goods stored in the automated warehouse 22, and the number of goods that can be stored in one storage container 90. The physical number of storage containers 90 to be stored in the automated warehouse 22 is calculated from. For example, when the number of goods stored in the automated warehouse 22 is 280 and the number of goods that can be stored in one storage container 90 is 20, the physical storage container 90 stored in the automated warehouse 22 is physically stored. The number of warehousing will be 14.
Further, the conveyor controller 35 calculates the number of storage containers 90 to be stored in the automated warehouse 22 from the number of orders for goods to be delivered from the automated warehouse 22. The number of storage containers 90 calculated here can accommodate the same articles even if the same articles are allocated in the sorting areas 11 and 12 during the sorting work of the articles in the sorting areas 11 and 12. An automated warehouse that takes into consideration the total number of storage shelves 23 of the automated warehouse 22 (the number of storage containers 90 that can be stored in the automated warehouse 22) so that the stored containers 90 do not stay in specific sorting areas 11 and 12. This is the optimum number of storage containers 90 for the number of orders for goods to be delivered from 22. For example, when the number of orders for goods from a customer is 124, the number of orders for goods to be delivered from the automated warehouse 22 is used as a reference so that the number of storage containers 90 to be stored in the automated warehouse 22 is 12. Set. Here, by setting the number of warehousing of the storage container 90 to the same number as the number of orders for goods to be delivered from the automated warehouse 22, it is possible to prevent the storage container 90 from staying in the specific sorting areas 11 and 12, but the customer. As the number of orders for goods from the automated warehouse 22 increases, the number of storage containers 90 stored in the automated warehouse 22 also increases, so that the capacity of the automated warehouse 22 may be exceeded depending on the number of ordered goods. Therefore, the number of storage of the storage container 90 is an article to be delivered from the automatic warehouse 22 after considering the total number of shelves of the storage shelf 23 of the automated warehouse 22 (the number of storage of the storage container 90 that can be stored in the automated warehouse 22). It is calculated according to the number of orders.
Then, the conveyor controller 35 receives the physical number of storage of the storage container 90 calculated according to the number of goods received in the automated warehouse 22 (the number of goods received in the receiving place 21) and the number of goods received in the automated warehouse 22. The number of storage containers 90 calculated according to the number of orders for goods to be delivered is compared with the number of storage containers 90, and the one with the larger number of storages is set as the recommended value for the number of storage containers 90 to be stored in the automated warehouse 22. For example, the physical number of storage containers 90 calculated according to the number of goods received in the automated warehouse 22 is 14, and the number of storage containers 90 calculated according to the number of orders for goods delivered from the automated warehouse 22 is stored. When the number is 12, the physical number of storage containers 90 (14 pieces) calculated according to the number of goods stored in the automated warehouse 22 having a large number of warehouses is stored in the automated warehouse 22. It is set as a recommended value for the number of storage containers 90 to be stored. The conveyor controller 35 calculates and sets a recommended value of the number of storage containers 90 to be stored in the automated warehouse 22 for each article to be stored in the automated warehouse 22. The conveyor controller 35 displays the calculated number of stored containers 90 as a recommended value on the display device 37 provided in the receiving place 21 for each item to be stored in the automated warehouse 22. The worker H of the receiving place 21 distributes and stores the goods in the storage containers 90 of the number of warehousing displayed on the display device 37, and puts the storage containers 90 containing the goods into the receiving conveyor 31.
In this way, in the article storage facility 20, the number of physical receipts of the storage container 90, which is the minimum necessary for accommodating the articles received in the arrival place 21, and the number of orders for the articles to be delivered from the automated warehouse 22 are set. On the other hand, by comparing with the optimum number of storage containers 90 and calculating the recommended value of the number of storage containers 90 to be stored in the automated warehouse 22, the number of goods received in the storage area 21 is large. In this case, the number of items stored in the storage container 90 is determined according to the number of items received, and if the number of items received in the receiving place 21 is small but the number of items ordered from the automated warehouse 22 is large, the items are stored. The number of storage containers 90 can be determined according to the number of orders.

Next, when the number of storage containers 90 stored in the automated warehouse 22 exceeds the total number of storage shelves 23 in the automated warehouse 22, the storage of the storage containers 90 in the automated warehouse 22 will be described.
In the article storage facility 20, as described above, a plurality of the same articles are used in consideration of the case where the same articles are assigned in the sorting areas 11 and 12 during the sorting work of the articles in the sorting areas 11 and 12. It is necessary to distribute and store the container 90 in the storage container 90 and store it in the automated warehouse 22. Therefore, the conveyor controller 35 calculates the total number of storage containers 90 to be stored in the automated warehouse 22 from the recommended value of the number of storage containers 90 to be stored in the automated warehouse 22 described above, and the calculated storage container 90 is calculated. The total number of required shelves of the storage shelves 23 of the automated warehouse 22 required for the total number of warehousing is calculated.
On the other hand, in the goods storage facility 20, the number of goods received in the storage container 90 for storing the goods increases due to a timing factor or the like, and the number of goods stored in the automated warehouse 22 increases. The total number of shelves in 23 (the number of storage containers 90 that can be stored in the automated warehouse 22) may be exceeded.
Therefore, in the article storage facility 20, the total number of required shelves 23 of the storage shelves 23 of the automated warehouse 22 and the total number of shelves 23 of the storage shelves 23 of the automated warehouse 22 with respect to the total number of storage containers 90 stored in the automated warehouse 22. By comparing the above, the number of storage containers 90 stored in the automated warehouse 22 is controlled.
Specifically, in the conveyor controller 35, according to the above comparison, the total number of storage shelves 23 of the storage shelves 23 of the automated warehouse 22 is the required shelves of the storage shelves 23 of the automated warehouse 22 with respect to the total number of storage containers 90 in the automated warehouse 22. If it is determined that the number is greater than the total number, the number of storage containers 90 stored in the automated warehouse 22 does not exceed the total number of storage shelves 23 in the automated warehouse 22, and the storage container 90 calculated by the conveyor controller 35. According to the recommended value of the number of warehousing, the storage container 90 is warehousing in the automated warehouse 22.
On the other hand, in the conveyor controller 35, according to the above comparison, the total number of shelves 23 in the storage shelves 23 of the automated warehouse 22 is the required number of shelves 23 in the storage shelves 23 of the automated warehouse 22 with respect to the total number of storage containers 90 in the automated warehouse 22. If it is determined that the number is less than the total, the number of storage containers 90 in the automated warehouse 22 exceeds the total number of storage shelves 23 in the automated warehouse 22, and the conveyor controller 35 determines that the number of storage containers 90 in the automated warehouse 22 is less than the total. The recommended value of the number of storage containers 90 to be stored in the automated warehouse 22 is calculated again so that the total number of storages in the automated warehouse 22 is smaller than the total number of storage shelves 23 in the automated warehouse 22. As a result of the conveyor controller 35 calculating the recommended value of the number of storage containers 90 to be stored in the automated warehouse 22 again, the total number of storage shelves 23 in the automated warehouse 22 is the total number of storage containers 90 in the automated warehouse 22. When the total number of storage shelves 23 of the automatic warehouse 22 exceeds the total number of required shelves, the storage container 90 is automatically stored in the storage container 90 according to the recommended value of the number of storage containers 90 recalculated by the conveyor controller 35. To be stocked in.
On the other hand, as a result of the conveyor controller 35 calculating the recommended value of the number of storage containers 90 to be stored in the automated warehouse 22 again, the storage shelf of the automated warehouse 22 with respect to the total number of storage containers 90 in the automated warehouse 22. If the total number of required shelves of 23 still exceeds the total number of shelves of the storage shelves 23 of the automated warehouse 22, the recommended value of the number of storage containers 90 recalculated by the conveyor controller 35 is adopted as it is and is accommodated. The container 90 is stored in the automated warehouse 22. Here, the conveyor controller 35 targets the goods scheduled to be stocked in the stockyard 21 and is scheduled to be stocked in the stockyard 21 with respect to the number of stored goods (stock quantity) stored in the automated warehouse 22. The ratio of the number of remaining shipments of goods (the number of goods to be received in the automated warehouse 22) is calculated. That is, the conveyor controller 35 calculates a value obtained by dividing the number of goods in stock stored in the automated warehouse 22 by the number of remaining shipments of goods scheduled to be stored in the arrival place 21. When the conveyor controller 35 calculates the ratio, the conveyor controller 35 displays the article name and the ratio on the display device 37 in ascending order of the articles with the smallest ratio. That is, the display device 37 displays the article names and their ratios in the order of articles in which the articles are likely to be out of stock in the automated warehouse 22.

Since the goods are sorted and stored in the automated warehouse 22, even if the same goods are assigned in the sorting areas 11 and 12 on the downstream side of the automated warehouse 22, the goods in which the allocations are duplicated are calculated. Each of the number of storage containers 90 can be sorted and stored, and the respective storage containers 90 in which the articles are sorted and stored can be transported to the sorting areas 11 and 12. Therefore, the articles with overlapping allocations do not stay only in the specific sorting areas 11 and 12, and can be sorted and transported to the respective sorting areas 11 and 12. Therefore, it is possible to improve the efficiency of the sorting work of the goods in the sorting areas 11 and 12.
In the article storage facility 20, since the articles stored in the automated warehouse 22 in a small number and the articles scheduled to be stored in the automated warehouse 22 can be preferentially stored in the automated warehouse 22, the articles can be stored in the automated warehouse 22 according to the number of orders. , Goods can be efficiently discharged from the automated warehouse 22.

In the present embodiment, the conveyor controller 35 makes various determinations in the storage of the storage container 90 in the automated warehouse 22 and calculates each numerical value, but the present invention is not limited to this, and the control controller 50 is not limited to this. May make the judgment, the calculation, etc. That is, the calculation device of the present invention is not limited to the conveyor controller 35, and may be another controller such as the control controller 50.
In the present embodiment, if the total number of storage shelves 23 of the automated warehouse 22 is less than the total number of required shelves of the storage shelves 23 of the automated warehouse 22 with respect to the total number of storage containers 90 in the automated warehouse 22, the conveyor When the controller 35 determines, the storage container to be stored in the automated warehouse 22 again so that the total number of storage containers 90 in the automated warehouse 22 is smaller than the total number of storage shelves 23 in the automated warehouse 22. The recommended value for the number of warehousing of 90 is calculated, but the recommended value is not limited to this, and the recommended value calculated at the first time is adopted as it is without recalculating the recommended value, and the storage container 90 is used as an automated warehouse. You may store it in 22.
In the present embodiment, the storage container 90 is charged into the arrival conveyor 31 by the worker H at the arrival place 21, but the present invention is not limited to this, and the storage container 90 may be automatically charged by the loading device or the like. I do not care.
