。[Prior Art] Conventional multi-level warehouses that store products of different heights have shelves of different heights and store them according to their heights. I am looking for a higher shelf to store it. If a shelf with a lower height than the one on which it was temporarily stored becomes empty, this technique involves rearranging the items several times until the items are stored on a shelf with the corresponding height.

Allocation is performed from a to middle shelf b. Next, when a space becomes available on the low shelf c, the middle shelf b is transferred to the low shelf c.

The storage position of the product and the height of the stored product are stored in association with each other, and when rearranging after receiving the product, the rearrangement of the product of small height stored on the shelf of large height is performed using the height of the product of small height. It is characterized by what to do when an empty shelf occurs on the shelf.

いない空時間に行なわれる。The height of the product is determined in the loading/unloading trolley 4 shown in FIG. When pallet height detectors 11, 12, and 13 are working, it is a high product, when pallet height detectors 11 and 12 are working, it is a medium product, and when only pallet height detector 11 is working, it is a small product. Product. (Step S1) If it is determined that the product is high quality in step S1, the high shelf a shown in FIG.
Find an empty shelf. (Step S5) Step S1
If it is determined that the product is a medium product, an empty shelf of the middle shelf b shown in FIG. 3 is searched. (Step S10) If there is no empty shelf in step S10, the process proceeds to step S15. Search for an empty shelf on high shelf a to store medium-sized products on the high shelf. (Step S15) If it is determined that the product is low quality in step S1,
Search for an empty shelf on the low shelf c shown in FIG. (Step S
20) If there is no empty shelf in step S20, the process proceeds to step S25. Middle shelf b to store low-quality products on the middle shelf
Find an empty shelf. (Step S25) Step S
If there is no empty shelf in step 25, the process proceeds to step 30. In order to store low-quality products on the high shelf, search for an empty shelf on high shelf a. (Step S30) Steps S5, S10, S1
5. The empty shelves found in S20, S25, and S30 are determined as storage shelves. (Step S35) Next, high shelf a, middle shelf b
A method for determining the allocation shelves for medium-sized products and low-quality products stored in the storage system will be explained with reference to the flowchart in FIG. This rearrangement is performed during idle time when loading and unloading operations using the stacker crane 2 are not being performed.

うものである。Products are stored in the storage shelves determined according to the flowchart in FIG. This high product, medium product,
The computer 5 shown in FIG. 4 memorizes which shelves the low-quality products are stored on. Therefore, if a shelf storing medium products is found on high shelf a, the process proceeds to step 5. High shelf a
, if you search for a shelf where low-quality products are stored on middle shelf b,
Proceed to step 10. (Step S51) Step S
If you search for a shelf where medium products are stored on a high shelf in step 51,
Search for an empty shelf on the middle shelf b shown in FIG. (Step S
55) When the high shelf and the middle shelf are searched for in step S51, an empty shelf of the low shelf c shown in FIG. 2 is searched. (Step S60) Steps S55, S60
The empty shelf found in is determined as the replacement shelf. (Step S6
5) In this way, the rearrangement of medium and low products stored on shelves a and b, which are higher than their own products, is as follows:
Rearrangement is performed only if there is a shelf where the product should be stored. For example, if a low-quality product is currently stored on high shelf a, it will not be rearranged even if there is an empty shelf on middle shelf b, but it will be rearranged only if there is an empty shelf on low shelf c. It is something.
【００２１】このため、配替え回数の管理を不要にでき
