Abstract

The invention relates to a process for the control of the position of workpiece and tool with a robot in a production machine. The objective of the invention is to reduce non-productive secondary processing time during the processing or measuring of a workpiece with a robot. The invention consists of a process for the control of the position of workpiece and tool with a robot in a production machine in which the workpiece ( 10 ) is positioned relative to the tool ( 1 ), ( 2 ) and during a continuous movement of the workpiece ( 10 ) with a tool ( 1 ), ( 2 ) at the processing location of the workpiece ( 10 ) a process takes place, and the tool ( 1 ), ( 2 ) is moving during the process synchronously to and in the same direction like the workpiece ( 10 ) and during the continuous movement of the workpiece ( 10 ) the tool ( 1 ), ( 2 ) is moved to and positioned in another processing location.

Claims (11)

1. A method for controlling position of a workpiece ( 10 ) and a tool ( 1 , 2 ) with a robot ( 9 ) in a manufacturing machine, comprising:

positioning the workpiece ( 10 ) relative to the tool ( 1 , 2 ),

processing the workpiece with the tool during a continuous movement of the workpiece ( 10 ) at a processing location of the workpiece ( 10 ) in which the tool ( 1 , 2 ) is moving during the processing synchronously to and in the same direction as the workpiece ( 10 ), and

during the continuous movement of the workpiece ( 10 ), positioning the tool ( 1 , 2 ) in another processing location.

2. The method according to claim 1 , wherein

the workpiece ( 10 ) is moved on an arm ( 12 ) of the robot ( 9 ) and wherein the tool ( 1 , 2 ) is moved linearly back and forth with a separate drive ( 4 , 5 ).

3. The method according to claim 1 , wherein

two workpieces ( 10 ) are moved together and joined by the tool ( 1 , 2 ).

4. The method according to claim 1 , wherein the workpiece ( 10 ) and the tool ( 1 , 2 ) are positioned with different robots.

5. The method according to claim 1 , wherein

during the processing, workpiece ( 10 ) and tool ( 1 , 2 ) are moved with constant velocity.
