CONSTITUTION:Stacked boxes are shifted by a robot or the like to the mount section 24 of a lifter 19 stopped at a shifting stage, then conveyor rollers 21 are driven by a control signal to convey them to a fixed position of the mount section 24. Next, the mount section 24 is lowered to the lower end of a shift section 11 and is shifted to a stock section 12 by the rollers 21, and the boxes are delivered to the mount section 33 of the stock section 12. When pats boxes on the lifter 13 of a row disposal section 13 are discharged, a mount section 41 is lowered tot he same height as that of the mount section 33 of the stock section 12, parts are taken out in sequence starting from the top-row parts box, vacant boxes are stacked on the mount section 41, and stacked vacant boxes are carried out by rollers of the disposal section 13.
