Self-positioning multilayer storage bookcase and system

The invention discloses a self-positioning multilayer storage bookcase and system. The self-positioning multi-layer storage bookcase comprises an annular bookshelf which is vertically arranged and can rotate along the central axis, a mechanical gripper is arranged in the annular bookshelf, and the mechanical gripper can be driven by a driving part to ascend and descend in the vertical direction and move horizontally in the radius direction of the annular bookshelf; a notch is formed in the side face of the annular bookshelf and used for allowing the mechanical gripper to penetrate through, so that books clamped in the mechanical gripper can be transferred between an inner cavity and the outside of the annular bookshelf. 本公开涉及一种自定位多层收纳书橱及系统，包括竖向设置且能够沿中心轴线自转的环形书架，环形书架中设有机械手爪，机械手爪能够在驱动件的带动下沿竖向升降以及沿环形书架半径方向平动；环形书架的侧面设有缺口，缺口用于穿过机械手爪，以使得机械手爪中夹持的书籍在环形书架内腔及外部之间转移。
