Stacking system

The embodiment of the invention provides a stacking system, and relates to the technical field of automatic loading. The stacking system aims to improve the stacking efficiency. The stacking system comprises a conveying device used for conveying stacking objects to a waiting platform, a movable loading device comprising a plurality of receiving platforms which are sequentially arranged at intervals in the vertical direction, a folding elevator comprising a plurality of lifting platforms which are movably arranged in the vertical direction, and a pushing device, wherein the multiple lifting platforms are used for sequentially moving to a feeding station in the vertical downward direction so as to receive the stacked objects moved out of the waiting platform; and the pushing device is used for pushing the stacked objects on the waiting platform to the lifting platforms located on the feeding station and used for pushing the stacked objects on the multiple lifting platforms to multiple receiving platforms in a o
