  • the IDs of the buckets 26 arranged in the depth direction of the shelves 24 are read, and the moving speed of the stacker crane 4 is high. For this reason, IDs of surrounding frontage other than the target frontage are often read at the same time. Therefore, the ID of one bucket is often stored in association with a plurality of frontages. Note that when the RFID 30 of the bucket 26 is read by running the stacker crane 4 at a low speed using an antenna having high directivity, such a problem does not occur. However, highly directional ID readers are expensive and take time to inventory.

The reason that the frontage where the bucket ID exists may be different between the inventory file 61 and the reading file 6 is that the directivity of the ID reader / writer is low and the moving speed of the stacker crane 4 is high. is there.
