Workpiece support system

A workpiece support system comprising:

• a workpiece support device that supports a workpiece by a support body having a support that comes in contact with the workpiece;
• and
• a robot that is separately provided outside the workpiece support device and moves the support, wherein
• the support is configured to be movable within a predetermined range and lockable at an arbitrary position,
• by clamping a robot-clamped component of the support body, the robot unlocks the support and moves the unlocked support according to a shape of the workpiece,
• the support body includes an X-slide, a Y-slide, and a Z-slide, each of which is unlocked to move the support,
• the robot-clamped component unlocks the support by being supplied with air,
• the Z-slide is unlocked to become slidable by being supplied with the air, and the X-slide, Y-slide and Z-slide are interlocked so that when the Z-slide is unlocked, the X-slide and Y-slide are also unlocked to become slidable,
• the robot has a tool assembly that supplies the air, and
• as the tool assembly of the robot clamps the robot-clamped component of the support body, the air is supplied from the tool assembly to the robot-clamped component and the support is unlocked.
