Devices for altering the position of the scanning element unit on inclined installation of a segmented grinding platen and controller for control thereof

Abstract

On inclined installation of the segmented grinding platen ( 11, 12, 13 ) of a through belt grinding machine, the problem arises of the altered arrangement of the scanning element series ( 15 ) relative to a position for the segment series ( 11 ) which is different thereto, for example, at right angles. According to the invention, the resulting deviations are allowed for by the lateral displacement of the scanning elements by means of a lever device ( 16 ), or by a pivoting of the scanning element series in a parallelogram construct ( 18 ). The application of the segments ( 11 ), following the determination of the workpiece properties by the scanning elements ( 15 ), occurs using an individually programmable electronic controller.

1 . Device characterised in that sensing elements positioned prior to a segmented sanding block can be moved laterally in accordance with the degree of inclination of the segmented sanding block.  
   
   
       2 . Device as described in Patent  claim 1  characterised in that the separation of the sensing elements adjusts in accordance with the inclination.  
   
   
       3 . Device characterised in that the sensing elements positioned prior to an inclined segmented sanding block is moved parallel to and in accordance with the degree of inclination of the segmented sanding block.  
   
   
       4 . Control unit characterised in that the segments of a segmented sanding block, when inclined, can be controlled individually in accordance with the inclination.
