The automatic case warehouse 1 constructed as described above.
The process (product replenishment process) when a package is stored in each of the warehouse units 2a to 2j will be described with reference to the flowchart of FIG. This description shows a case where the deadline for the order from the customer is until the day before the shipping date, and the sorting and shipping operations are performed at a distribution center and a distribution center during the daytime from morning to evening.

First, a delivery permutation is determined from the order list containing orders up to the previous day in consideration of the delivery time of the shipping truck (step S1). Next, a picking batch is generated from the determined delivery permutation (step S2).
Here, the picking batch is an order port grouped in delivery destination units or time units. The total number of the type units in the generated picking batch is calculated (step S3), and the calculated total number of the type units and the warehouse units 2a to 2
The difference between the package in j, that is, the excess package generated in the previous package replenishment process is calculated. The calculated number of differences is cut out from the upstream device (step S4). The upstream device referred to here is a case accumulator that accumulates and stores in a case row for each product type, or a face picking device that cuts out one surface of a package 5 stored in a stacked state on a case flow rack or a pallet. When the parcels 5 are cut out, each warehouse unit 2 is provided for each parcel 5 according to the order of delivery.
The storage destinations of a to 2j are allocated. Each package 5 cut out from the upstream device is assigned to the assigned warehouse unit 2a-
2j and temporarily stored (step S5). At this time, in the packages corresponding to the same retrieval cycle, the warehouse units 2a arranged in the downstream of the central retrieval conveyor 4 are stored in order from the earlier retrieval order, and the warehouse units arranged in the upstream in the latest retrieval order. 2j. The surplus luggage generated at this time is temporarily stored in any of the warehouse units 2a to 2j after checking the availability thereof, and is used in the next and subsequent picking batches. FIG. 5 shows the generation of the picking batches according to the delivery permutation and the allocation status to the warehouse units 2a to 2j. Here, the capital letters represent the product names. As shown in FIG. 5, when the packages 5 to be unloaded in one unloading 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 varieties A with the earliest delivery order in the warehouse unit 2a arranged at the most downstream side of the central delivery conveyor 4, stores the varieties C in the storage order sequentially from the warehouse units 2b, and stores the varieties C with the latest delivery order in the central warehouse. It is stored in the warehouse unit 2j arranged at the most upstream of the conveyor 4. This process is repeated for each delivery cycle.

Next, as described above, each warehouse unit 2
The process (item release process) when the package 5 stored in a to 2j is retrieved will be described with reference to the flowchart of FIG.

The warehouse units 2a-2 according to the delivery permutation
The luggage 5 stored in j is processed in one retrieval cycle unit. Here, the delivery cycle unit refers to a unit corresponding to the number of units of the warehouse units 2a to 2j arranged in a line, for example, a unit of luggage 5 of 10 cases. A case transfer device 8 of each of the warehouse units 2a to 2j together with the outgoing order.
Are operated in parallel at the same time, the luggage 5 of the first retrieval cycle is retrieved to the retrieval conveyor 10 and paid out to the central retrieval conveyor 4 all at once (steps S11 and S12). In this way, the case transfer devices 8 of the warehouse units 2a to 2j are operated in parallel at the same time, and the outgoing luggage 5 is paid out to the central outgoing conveyor 4 all at once, so that the outgoing luggage can be quickly paid out. In addition, since the storage units 2a to 2j store the luggage 5 in accordance with the outgoing permutation, the outgoing luggage 5 can be arranged in the central outgoing conveyor 4 in accordance with the outgoing permutation. 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 collectively deliver the packages 5 to the downstream patterizer or the shipping port 12 (step S13). This process is repeated for each retrieval cycle until one picking batch is completed. When one picking batch is completed, the loading process of the package 5 is performed again.

By repeating the loading and unloading processing of the parcels 5, the parcels 5 ordered can be discharged at a high speed in the required departure order. In addition, if an error occurs during the loading or unloading process of the package 5, the central storage conveyor 3 and the central storage conveyor 4 are formed in a loop, so that the package 5 can be passed again and temporarily evacuated. , When it has gone around, the warehouse unit 2a ~
The problem is dealt with by re-entering a predetermined warehouse unit in 2j and then re-exiting.
