Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and in particular to a stacker crane. Background Technology

[0002] In automated warehousing systems, stacker cranes transport cassettes within the system. The stacker crane performs numerous tasks: moving cassettes from the upstream handling system into the warehousing system, moving cassettes to temporary storage locations on multiple processing machines, moving finished cassettes back into the warehousing system, and moving cassettes to temporary storage locations on the downstream handling system. Thus, the stacker crane needs to perform many actions and travel a long distance.

[0003] CN111891983B discloses a stacker crane, including a lifting mechanism, a translation mechanism, a platform, a frame, and an unloading mechanism. The translation mechanism is installed at the lower end of the frame and drives the frame to translate, thereby stacking items in different positions. The platform is slidably installed on the frame and is used to carry items to be stacked. The lifting mechanism is connected to the platform.

[0004] In use, there are multiple shelves inside the warehouse, and the spacing between the shelves is narrow. In narrow aisles, it is inconvenient for the stacker crane to turn. Stacker cranes that can transport and stack to both sides require workers to move the pallets to the top of the stacker crane's top plate and move them through the telescopic device. In addition, a lifting device needs to be installed above the shelves to support the pallets, which makes the manufacturing cost high. Therefore, we have proposed a stacker crane.
