After the grinding wheel sheets and the gaskets on the stacking seats 54 are taken away, the empty stacking seats 54 are placed on the electromagnets 53 for repeated use. In this way, the stacking seats 54 are very convenient to take and place. The electromagnets 53 are charged to attract the stacking seats 54, so that the stacking seats 54 are stable during the rotation and cannot shake.

[0043] In the embodiment, the gasket storage device 3 can adopt the same structure design as the grinding wheel piece storage device 2, but considering that the gasket is more likely to be sucked and not easy to be damaged compared with the grinding wheel piece, the mechanism for lifting the gasket in the gasket storage device 3 can be driven by a cylinder lifting assembly, which has the same structure as the stacking buffer mechanism 57, so as to reduce the cost.
