Patent ID: 8616150

Claim:
A device for blocking workpieces, for processing and/or coating thereof, comprising: a support for supporting the workpiece to be blocked, a blocking station, in which the workpiece can be blocked on a block piece with a temporarily deformable blocking material, a transport device having a holding head for the workpiece that provides a relative movement between the workpiece held at the holding head on the one hand and the support as well as the blocking station on the other hand for transporting said workpiece between said blocking station and a loading unit, said transport device having at least four closed-loop drives configured to control movement of the workpiece held at said holding head in a defined manner relative to a block piece disposed in the blocking station with consideration of orientation and of geometry data of the workpiece, and to hold the workpiece stationary during the blocking in the defined relative position with respect to the block piece while leaving a blocking material receiving gap between workpiece and block piece, three of said at least four closed loop drives being configured to move said workpiece along a respective single axis that is mutually orthogonal to two other axes of motion to position said workpiece along the respective single axis such that said three of said at least four closed loop drives are constructed to move said holding head along a respective axis independent of the other's position and positioning, and one of said at least four closed loop drives being configured to rotate said holding head for said workpiece about one of said respective single axes.
