[0001]
BACKGROUND OF THE INVENTION
In the present invention, shipment is performed in an automatic warehouse that handles a loading pallet in which fractional items that can be picked in units of layers are stacked on one pallet, and fractional items are loaded on the uppermost layered item. It is about the system.
[0002]
[Prior art]
As shown in FIG. 1, for example, a loading pallet in which a plurality of layers of the same article 1 such as a case are arranged on a pallet and a plurality of layer unit articles 1A that can be picked in units of layers is handled. In an automatic warehouse, there are cases where an article having a fraction less than the number of articles forming one layer is picked and shipped from the uppermost layer unit article group of the loaded pallet.
[0003]
As a result of such picking shipment, there is a loading pallet in which the fractional article 1B remains in the uppermost stage, that is, a mixed loading pallet 3 with a fraction and a layer. In the past, when the article is to be shipped, the fractional article 1B is picked, placed on another pallet and re-entry, and the target layer unit article is loaded from the loading pallet 4 consisting of only the remaining layer unit article group. The group 1A was picked and shipped, and the loading pallet 4 consisting only of the remaining layer unit article group 1A was re-stocked. As a result, for example, the same lot of articles 1 originally loaded on the same pallet 2 are divided into fractional articles 1B and layer unit article groups 1A, and are separately re-stocked and stored. If management was not devised, there was a disadvantage that the first-in first-out principle was not followed and lots were reversed. In addition, the number of pallets increases and the storage efficiency of the automatic warehouse decreases.
