摘要： A workpiece holding tool changing system is configured to change at least one of a relative position and a posture of a holding tool T1 to Tn of a workpiece conveying apparatus (100) with respect to a feed bar 101R. The feed bar 101R includes at least one set among: a set of an X-axis direction linear mechanism 320 and an X-axis linear brake 321; a set of a Y-axis direction linear mechanism (330) and a Y-axis linear brake 331; a set of a Z-axis direction linear mechanism (340) and a Z-axis linear brake 341; and a set of a ball joint portion 310 and a ball brake 311. Under a state in which inhibition of movement or change in posture by a corresponding brake is canceled, a robot RR1 changes the relative position or the posture of the holding tool T1 to Tn to a desired relative position or a desired posture. After the change, the workpiece holding tool changing system is brought into a holding state in which the movement or the change in posture is inhibited.
