Material tray warehousing method and system guaranteeing accurate material receiving by automatic navigation trolley

Abstract

The invention discloses a material tray warehousing method and system guaranteeing accurate material receiving by an automatic guided vehicle. The material tray warehousing method comprises the steps that when the automatic guided vehicle arrives at a material receiving platform and gets ready for fetching materials, a material receiving information verification request is sent to a warehouse dispatching platform; the warehouse dispatching platform acquires the current index number Index l of the automatic guided vehicle and searches for the corresponding predistribution transfer task number task 1 according to the index number Index l; the warehouse dispatching platform compares the task 1 and a current transfer task number task 2 provided by an electric control unit, wherein the task 2 is the transfer task number corresponding to a material container on the material receiving platform currently; if the task 1 is equal to the task 2, the warehouse dispatching platform sends a verification success instruction to the automatic navigation trolley; the automatic guided vehicle continues to receive the materials and transfer the material container to a target position. According to the material tray warehousing method and system guaranteeing accurate material receiving by the automatic guided vehicle, it is guaranteed that the AGV does not receive the material incorrectly in the material receiving process, an extra guarantee is provided for conformance between system record information and reality after the container is warehoused, and therefore production quality accidents caused by container warehousing dislocation can be avoided as far as possible.

Description

Technical field [0001] The invention relates to the field of tobacco automated logistics, and in particular to a method and system for warehousing material trays that ensure the accurate receiving of goods by an automatic navigation cart. Background technique [0002] With the development of cigarette production and the improvement of logistics automation, the automated guided vehicle AGV (Automated Guided Vehicle, AGV) has become an important handling tool in the logistics system. In the traditional automated logistics warehouse system with AGV as the main handling tool, AGV The warehousing methods for handling operations usually include: [0003] Step 101: The container with the material arrives at the warehousing application platform, and sends a warehousing request to the warehouse management platform, and the warehouse management platform receives and generates AGV transportation and warehousing task information. [0004] Step 102: The container continues to move forward to a c...

Problems solved by technology

[0010] In the AGV pick-up link of step 105, there is still a certain time interval between the AGV receiving the task and the start of handling. match, and the AGV did not check the container information again when picking up the goods, as long as there is a container at the receiving platform, it will be picked up, so this mechanism cannot guarantee that the container that the AGV picks up each time is the one originally allocated by the system, that is, it is easy to generate The phenomenon of wrong connection will lead to the discrepancy between the actual material information of the container and the information recorded in the system after the container is put into the warehouse. When the container is out of the warehouse, it may cause quality production accidents
