METHOD FOR DISCRIMINATING SPECIFICATION OF TIRE WHEEL BALANCE WEIGHT FOR IMPROVING QUALITY OF TIRE BY PREVIOUSLY PREVENTING OPERATOR'S WRONG INSTALLATION OF BALANCE WEIGHT

摘要

PURPOSE: A specification discrimination method of a tire wheel balance weight is provided to prevent the shaking event of wheels and to improve the quality of a tire by preventing wrong installation of the balance weight. CONSTITUTION: A tire is rotated by using a servo motor(120) after centering the tire in a tire centering device(110). A displacement change point by a balance weight is checked by using a displacement sensor(130). An encoder value of the servo motor is read by receiving a signal when the displacement is changed(150). An encoder value of the servo motor is read by receiving a displacement change signal when the balance weight displacement is finished(170). An encoder displacement amount of the servo motor is calculated(190). A balance weight length is calculated(200). A balance weight specification by the balance measurement and a balance weight specification by the displacement sensor measurement are compared and discriminated(210). Thereby, the wrong installation of the balance weight is prevented.
