Abstract
A component transfer device includes a detector configured to detect a rotation angle of a driving motor that moves a pair of gripping sections, or a position of the gripping sections, and a motor control section configured to perform position feedback control of the driving motor based on a detection signal of the detector and a position command signal from the transfer control device. A transfer control device is provided with a torque monitoring section configured to monitor a value of a command torque applied to the driving motor from the motor control section, and a gripping state determining section configured to determine that there was a change in a gripping state of the component when, with the pair of gripping sections in a state gripping the component, the command torque monitored by the torque monitoring section drops to a value smaller than a first threshold value.
