Grinding apparatus for treatment of a surface

Abstract

The present invention concerns a grinding apparatus ( 1 ) for processing a workpiece ( 20 ), including a support arrangement ( 4 ) for a number of grinding heads ( 6 ) that each includes a grinding element ( 2 ) and a grinding motor ( 3 ) driving an associated grinding element ( 2 ), where the support arrangement ( 4 ) includes an endless conveyor means ( 9 ) for the grinding heads ( 6 ), the conveyor means ( 9 ) being driven in an annular path with at least one long side perpendicular to an underlying conveyor, by at least one moving motor ( 5 ) for establishing an epicyclic movement of the grinding elements ( 2 ) across the work piece ( 20 ) during operation.

1 . Grinding apparatus ( 1 ) for processing a workpiece ( 20 ), including a support arrangement ( 4 ) for a number of grinding heads ( 6 ) that each includes a grinding element ( 2 ) and a grinding motor ( 3 ) driving an associated grinding element ( 2 ), characterised in that the support arrangement ( 4 ) includes an endless conveying means ( 9 ) for the grinding heads ( 6 ), the conveyor means ( 9 ) being moved in an annular course by at least one moving motor ( 5 ) for establishing an epicyclic movement of the grinding elements ( 2 ) across the work piece ( 20 ) during operation.  
   
   
       2 . Grinding apparatus ( 1 ) according to  claim 1 , characterised in that the conveyor means ( 9 ) is constituted by a number of drive chains or belts which are adapted for engaging with a drive wheel ( 11 ) driven by the moving motors ( 5 ).  
   
   
       3 . Grinding apparatus ( 1 ) according to  claim 1 , characterised in that it includes an apparatus frame ( 7 ) in which the support arrangement ( 4 ) is adjustable in height arranged by means of a number of displacing force providers ( 12 ).
