PROBLEM TO BE SOLVED: To accurately measure weight of a work without providing a special station by measuring weight of the work using a high resolution load cell provided in a main body, and to sort the work by weight by changing a place where the work is conveyed with corresponding to a measured weight. SOLUTION: A computer provided in a main body 16 controls a robot system to move an arm 20 to a storage space for a work and make the arm 20 hold the work. Weight of the held work is measured by a high resolution load cell 18. The computer captures weight data from the load cell 18 and determines a place where the work is conveyed according to the weight of the work. Namely, the work is conveyed to a normal position when the weight is within a specified range and to an eject position when the weight is out of the specified range.
