Abstract
Provided is a workpiece holding tool changing system configured to change at least one of a relative position and a posture of a holding tool of a workpiece conveying apparatus with respect to a feed bar. The feed bar includes at least one set among: an X-axis direction linear mechanism with an X-axis linear brake; a Y-axis direction linear mechanism with a Y-axis linear brake; a Z-axis direction linear mechanism with a Z-axis linear brake; and a ball joint portion and a ball brake. Under a state in which inhibition of movement or change in posture by a corresponding brake is canceled, a robot changes the relative position or the posture of the holding tool 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.
