<p>PURPOSE:To make it easy to position a workpiece by selecting a reference pin corresponding to the kind of a workpiece based on the information identifying the kind of the workpiece, projecting the pin on a pallet and also positioning the workpiece according to the reference pin. CONSTITUTION:After a plurality of reference pins 8 to 10 provided to a pallet 1 are set below the surface of the pallet 1 by a resetting device respectively, the projection state of the detection pin 3 provided to the display section 4 of the pallet 1 is read out by the sensor of a model identifying station to identify a workpiece W. And a reference pin used for positioning a workpiece W to be placed on the pallet 1 based on the discriminant information is selected, and the workpiece W is positioned with the reference pin projected on the pallet 1 by a thrust-up cylinder. For this reason, one kind of pallets 1 can be coped with a plurality of workpiece W. The operations after positioning can, therefore, be done by positioning and fixing the machining reference position of the workpiece W to the specified position on the pallet 1.</p> |
