Abstract
A workpiece loading apparatus 100 includes a pick-up stage 31, an A-side palletizing stage 41 and a B-side palletizing stage 141, an A-side lifting device 42, a B-side lifting device 142, and a workpiece transfer device 60. The workpiece transfer device 60 is configured to transfer a workpiece 4 picked up from the pick-up stage 31 to one of an A-side stocker 44 or a B-side stocker 144 until the stocker becomes full, and a corresponding one of the A-side lifting device 42 or the B-side lifting device 142 is configured to operate so that a height of the corresponding one of the A-side stocker 44 or the B-side stocker 144 is aligned with a workpiece horizontal movement height of the workpiece transfer device 60. When one of the A-side stocker 44 or the B-side stocker 144 becomes full, the workpiece transfer device 60 switches an operation to transfer of the workpiece 4 to another one of the stockers 44, 144.
