PROBLEM TO BE SOLVED: To provide an unloading device allowing unloading in any number except in one-line number while allowing unloading in each of lines. SOLUTION: The unloading device comprises suction pads 9, 9... arranged on a suction unit 20 for holding a negative pressure generated by a vacuum pump 11, a weight measurement available load sensor provided on a supporting part for suspending the suction unit 20 in a vertically movable manner and a controller for storing a specified number intended for unloading, finding a total number by adding numbers for gripping calculated from the measured weight and the unit weight. of a case W in sequence and instructing a solenoid valve mounted between the vacuum pump 11 and the suction pad 9 to cancel the gripping of the cases W in exceeding number when this total number exceeds the specified number.
