Considering that the same kind of materials can be delivered while being delivered, at present, some schemes are used for replenishing the first delivered and then unfilled containers again in the delivery process, so that the condition of replenishing the materials for many times occurs in the delivery process, the materials for replenishing the materials in the containers are always positioned above the materials put in the first delivery process, and then when the materials are delivered for the containers, operators can preferentially select the materials at the upper part of the containers according to working habits, so that the materials at the lower part of the containers are backlogged for a long time, and the shortest delivery time of the materials cannot be ensured. In order to solve the above problem, in this embodiment, the first time of storage is used to determine the storage sequence of the containers, specifically:
when the second container is used as the first container which is finally put into storage, the storage time is the first storage time of the corresponding first container, in the follow-up step, when the first container is completed for replenishment and put back into the stereoscopic warehouse, the storage time is not updated, the first storage time is still kept so as to facilitate the material delivery management, when the corresponding second container is used as the first container which is finally put into storage, the storage time is also the first storage time of the material in the second container, in the follow-up step, when the first container is completed for replenishment and put back into the stereoscopic warehouse, the storage time is the first storage time of the newly added material (i.e. the material in the time of replenishment), and the storage time of the original material (i.e. the material before the replenishment) is not updated, and the corresponding first storage time is still kept.
In this embodiment, the first time of storage of the materials may be achieved by means of manual recording, bar code recording, video image recording, etc., and the related implementation process is not the key point of this embodiment, and this embodiment also does not involve improvement of the specific implementation process thereof, and the specific implementation process for determining the first time of storage of the materials is not described here again.
As shown in fig. 2, the steps of delivering materials in this embodiment specifically include:
b1 Acquiring a material ex-warehouse request, wherein the material ex-warehouse request comprises information such as the types and the numbers of materials, and under the application scene of small batch, multiple varieties and frequent ex-warehouse entry, one material ex-warehouse request comprises information such as the types and the numbers of at least one material to be ex-warehouse, after acquiring the material ex-warehouse request, inquiring the warehouse-in time of all first containers corresponding to the material according to the types of the material ex-warehouse request, executing the step B2 for the material with the inquiring result, and prompting the material to be inventory-free and exit from the material ex-warehouse for the material without the inquiring result;
b2 Taking out the first container in which the materials are stored earliest, and sorting the materials in the first container out of the storage.
According to the embodiment, through the steps, the warehouse-out is performed according to the warehouse-in sequence of the containers, so that first-in first-out of materials is realized, and the related steps of the warehouse-out of the materials in the embodiment are described in detail below by taking single types of materials as examples.
