Multi-product pallet device, control system for multi-product pallet device, displacement-restricting mechanism, and conforming mechanism

A conforming mechanism comprising:

• a plurality of shafts;
• and
• a plurality of displacement-restricting mechanisms which restrict displacement of the plurality of shafts in an axial direction,
• wherein tip ends of the plurality of shafts are caused to conform to a shape of a workpiece,
• wherein each of the plurality of displacement-restricting mechanisms includes:
• an outer cylinder in which a tapered surface is formed on an inner peripheral surface of the outer cylinder surrounding a peripheral surface of the shaft;
• an inner cylinder disposed inside the outer cylinder;
• a rolling body held by the inner cylinder;
• and
• a pressing member that presses the rolling body toward the tapered surface through the inner cylinder,
• wherein the outer cylinder is movable relative to the inner cylinder in the axial direction in a state in which the inner cylinder does not move in the axial direction,
• wherein the conforming mechanism further comprises a conforming unit and a base member,
• wherein the base member includes a fixing part to which the conforming unit is fixed,
• wherein the conforming unit includes the plurality of shafts and the plurality of displacement-restricting mechanisms,
• wherein the tapered surface of the outer cylinder is reduced in diameter toward the fixing part,
• wherein the inner cylinder comes into contact with the fixing part and is not movable in a direction toward the fixing part in the axial direction of the shaft,
• wherein, due to a pressing by the pressing member, the rolling body held by the inner cylinder enters a wedge-shaped space formed between the peripheral surface of the shaft and the tapered surface of the outer cylinder, and then, the rolling body functions as a wedge, and the displacement of the shaft in the axial direction is restricted, and
• wherein a load is applied to the outer cylinder to move the outer cylinder in the axial direction with respect to the inner cylinder, rotate the rolling body, and release a displacement restriction of the shaft in the axial direction.
