[0002] In the process of intelligent logistics transfer in digital factories, it is often necessary to transfer materials between multiple floors. According to the process planning attributes, each floor has different material transfer methods. This requires that materials with different transfer methods on different floors be transferred to other floors for use according to the requirements of the production process. At present, multi-layer and multi-functional elevators generally do not realize the intelligence of the whole machine. Generally, materials are manually transferred from different docking ports to the freight elevator, and then the materials are transferred to the required floor through the freight elevator, and then manually transferred from the freight elevator to the required docking port. This method of manually transferring materials is time-consuming, labor-intensive, and inefficient. At the same time, manual transfer is not only costly, but also has a high error rate. In addition, different transfer methods are required for different floors. Manual transfer of materials often requires the operation of different handling tools to achieve docking, which has high requirements for porters and is difficult to recruit.

[0003] In the process of intelligent logistics transfer in existing digital factories, freight elevators and multiple hoists are also used in combination for multi-layer and multi-functional lifting. This combination often requires the use of multiple devices, which is very costly, and multiple devices occupy a large space, which is not conducive to the layout of digital factory workshops. At the same time, this ordinary hoist has a high safety risk and does not have the safety device and safety level of a freight elevator. In addition, ordinary chain hoists used on floors above 20 meters have a large settlement, making it difficult to achieve high-precision docking, and the speed is only 0.75m / s, which is difficult to meet efficiency requirements.

The AGV scheduling system schedules the AGV trolley to carry the pallet material from the pallet bracket on the first layer to the front of the fast door of the multi-layer multifunctional elevator. The AGV scheduling system then issues the arrival information of the AGV trolley. After receiving the arrival information of the AGV trolley, the multi-layer multifunctional elevator issues a fast door opening command. After receiving the information that the fast door has been opened, the AGV trolley automatically walks into the cabin of the multi-layer multifunctional elevator. After receiving the information that the AGV trolley has arrived in the cabin, the multi-layer multifunctional elevator automatically closes the fast door and automatically lifts the AGV trolley and the pallet material to the fourth floor. After the multi-layer multifunctional elevator arrives at the fourth floor, the fast door automatically opens, and the AGV trolley carries the pallet material out of the cabin of the multi-layer multifunctional elevator. Then the AGV scheduling system schedules the AGV trolley to carry the pallet material to the designated pallet bracket position, and the AGV trolley places the pallet material on the corresponding pallet bracket position. After completing the task, the AGV trolley waits for the AGV scheduling system to issue a new task.

9. A multi-layer multifunctional lifting system according to claim 1, characterized in that: The pallet transfer system includes a pallet docking position, pallet materials, and a logistics control system. The logistics control system dispatches the multi-layer multifunctional elevator to arrive at the second-layer pallet docking position. The rapid door automatically opens after the multi-layer multifunctional elevator fork arrives at the second-layer pallet docking position. The logistics control system dispatches the fork to take the pallet material on the second-layer pallet docking position and put it on the fork of the multi-layer multifunctional elevator. After the multi-layer multifunctional elevator receives the information that the pallet material has arrived at the fork and the fork has been retracted, it automatically closes the rapid door and automatically lifts the pallet material to the fifth-layer pallet docking position. After the multi-layer multifunctional elevator fork arrives at the fifth-layer pallet docking position, the rapid door automatically opens. The logistics control system dispatches the fork carrying the pallet material to automatically extend out of the multi-layer multifunctional elevator lifting and transfer component, and then the fork automatically places the pallet material to the fifth-layer pallet docking position.
