Abstract
Description
Technical Field
[0001] This utility model relates to the field of reflux elevator technology, and in particular to an aerial reflux elevator. Background Technology
[0002] In modern manufacturing, the transportation and storage of materials are crucial for ensuring the continuous and efficient operation of production lines. This is especially true in fields with high production cycle requirements, such as electronic component assembly and automotive parts manufacturing. The efficiency of material tray transfer and the convenience of storage directly impact overall production efficiency. Currently, AGVs (Automated Guided Vehicles) are commonly used in conjunction with automated conveyor lines to transport materials and pallets, and storage racks are used for centralized storage of materials or pallets. Specifically, in the production process: AGVs first transport pallets filled with materials from the storage area to the assembly conveyor line. After loading, empty pallets are transported to the recycling area by AGVs. When the capacity of a certain process exceeds that of subsequent processes, excess materials or pallets need to be temporarily stored on storage racks. This approach significantly increases the cost of transporting materials and pallets due to the primary use of AGVs for transfer. Furthermore, the AGV transfer process requires following a pre-set path, which can easily lead to congestion when there are many personnel and equipment in the workshop or temporary obstacles, resulting in extended transfer cycles and significantly reduced material transfer efficiency. Therefore, improvements are necessary. Utility Model Content
