To eliminate displacement in the stacked configuration occurring when stacking aluminum ingots by two-direction rotation at only 0 degree and 90 degree since an ingot stacking device used in the stacking device for aluminum ingots lacks accurate gripping of the ingot due to a link type mechanism of a claw of a grip part.

The claw of the grip part of the stacking device is made to be a horizontal opening/closing system by a cylinder 2, and a smooth and accurate gripping operation can be performed. The ingot can be stacked in a parallel-cross shape without displacement by four-direction rotation system at 0 degree, 90 degree, 180 degree, and 270 degree.
