The case automatic warehouse 1 constructed as described above
The processing (commodity replenishment processing) when the parcel is loaded into each of the warehouse units 2a to 2j will be described with reference to the flowchart of FIG. In this description, the deadline for the order from the customer is until the day before the shipping date, and the case where the distribution center and the distribution center perform the sorting and shipping work in the daytime hours from the morning to the evening is shown.

First, the shipping order is determined from the order list containing the orders up to the previous day while taking into account the delivery time of the shipping truck (step S1). Next, a picking batch is generated from the determined delivery sequence (step S2).
Here, the picking batch is an order port that is grouped by delivery destination or by time. The total number of product type units in the generated picking batch is calculated (step S3), and the calculated total number of product type units and each of the warehouse units 2a to 2 are already calculated.
The difference between the package within j, that is, the excess package generated in the previous package replenishment process is calculated. The number of calculated differences is cut out from the upstream device (step S4). The upstream device referred to here is a face picking device that cuts out one surface of the loads 5 stored in a stacked state on a case accumulation conveyor, a case flow rack, or a pallet that stores and stores a case row for each product type. When the parcels 5 are cut out, the respective warehouse units 2 are arranged for each parcel 5 according to the order of delivery.
Storage destinations a to 2j are assigned. Each of the packages 5 cut out from the upstream device is assigned to the warehouse unit 2a ...
It is distributed to 2j and temporarily stored (step S5). At this time, in the parcels corresponding to the same shipping cycle, the warehouse units 2a arranged in the order from the earliest shipping order to the warehouse unit 2a arranged on the downstream side of the central shipping conveyor 4 are stored in order, and the goods in the latest shipping order are arranged on the upstream side. 2j. The excess baggage generated at this time is temporarily stored in one of the warehouse units 2a to 2j in consideration of the vacancy status and used in the next picking batch or later. FIG. 5 shows the generation of picking batches according to the delivery sequence and the allocation status to the warehouse units 2a to 2j. Here, the capital letters represent the product name. As shown in FIG. 5, when the parcels 5 delivered in one delivery cycle are in the order of type A, type G, type C, type F, type F, type E, type H, type D, type B, type C. Stores the product type A with the earliest shipping order in the warehouse unit 2a arranged on the most downstream side of the central shipping conveyor 4, stores the product units in order from the warehouse unit 2b, and the product type C with the latest shipping order in the central shipping. It is stored in the warehouse unit 2j arranged at the most upstream side of the conveyor 4. This process is repeated for each shipping cycle.

Next, as described above, each warehouse unit 2
The process (commodity warehousing process) when unloading the parcel 5 stored in a to 2j will be described with reference to the flowchart of FIG.

The warehouse units 2a to 2 according to the delivery sequence.
The parcel 5 stored in j is processed in units of one shipping cycle. The shipping cycle unit here means a unit corresponding to the number of units of the warehouse units 2a to 2j arranged in line, for example, 10 cases of luggage 5. A case transfer device 8 of each of the warehouse units 2a to 2j together with a shipping instruction
Are simultaneously operated in parallel to deliver the cargo 5 in the first delivery cycle to the delivery conveyor 10 and to the central delivery conveyor 4 simultaneously (steps S11, 12). In this way, the case transfer devices 8 of the warehouse units 2a to 2j are simultaneously operated in parallel to deliver the packages 5 to be delivered to the central delivery conveyor 4 all at once, so that the packages to be delivered can be promptly delivered. In addition, since the packages 5 are stored in the warehouse units 2a to 2j according to the shipping sequence, the packages 5 to be shipped can be arranged on the central shipping conveyor 4 according to the shipping sequence. When the packages 5 are delivered from the warehouse units 2a to 2j to the central delivery conveyor 4, the central delivery conveyor 4 is driven to batch-deliver the packages 5 to the downstream patterner or shipping port 12 (step S13). This process is repeated for each shipping cycle until one picking batch is completed. When one picking batch is completed, the loading process of the parcel 5 is performed again.

By repeating the warehousing process and the warehousing process of the parcel 5, the parcel 5 for which an order has been placed can be evacuated at high speed in the required procuring order. If an error occurs during the loading or unloading process of the luggage 5, the central warehousing conveyor 3 and the central unloading conveyor 4 are formed in a loop, so that the luggage 5 is passed once again to be temporarily saved. , When it goes around, the warehouse unit 2a ~
