Description

TECHNICAL FIELD

[0002] In an automated warehouse system, when goods are moved from one area to another within the warehouse, the pallets may need to be changed to accommodate different storage or picking systems, and the pallets need to be changed to ensure compatibility with automated equipment such as automated guided vehicles (AGVs) and automated storage and retrieval systems (AS / RS). For example, the patent with application number CN202220651152.8 discloses a full-automatic pallet changer and conveyor. The full-automatic pallet changer includes a base frame, a pallet changing and overturning mechanism rotatably installed on the base frame, and a three-sided clamping mechanism rotatably installed on the base frame. The base frame is provided with a first driving mechanism for driving the three-sided clamping mechanism to overturn. The three-sided clamping mechanism is provided with a second driving mechanism for driving the pallet changing and overturning mechanism to overturn. The three-sided clamping mechanism and the pallet changing and overturning mechanism are controlled to overturn by driving the first and second driving mechanisms, thereby achieving the replacement of the pallets. The utility model clamps the material with the three-sided clamping mechanism, and then replaces the pallets with the pallet changing and overturning mechanism. The first and second driving mechanisms are driven to control the three-sided clamping mechanism and the pallet changing and overturning mechanism to overturn, thereby completing the replacement of the pallets.
