Device for automatically changing grinding discs

Abstract

A device ( 1 ) for automatically changing sanding discs ( 12 ) includes a stacking device ( 10 ) for a plurality of grinding discs ( 12 ) and a guide element ( 16 ) for orienting the suction openings ( 32 ) in the grinding discs ( 12 ) along a common central axis ( 18 ), wherein the guide element ( 16 ) is arranged eccentrically with regard to the central axis ( 18 ). A positioning element ( 17 ) is provided for positioning a tool head of a grinding device, wherein the positioning element ( 17 ) and the guide element ( 16 ) are mounted in a floating manner. A device ( 1 ) for automatically changing grinding discs ( 12 ) includes a detachment device ( 50 ), wherein the detachment device ( 50 ) has a bearing surface ( 51 ) for a grinding-disc receptacle. The bearing surface ( 51 ) has an opening ( 52 ), the diameter of which is greater than the diameter of the grinding disc ( 12 ). A separating element ( 53 ) is arranged above the opening ( 52 ). A system includes a device ( 1 ) for automatically changing grinding discs ( 12 ) containing a stacking device ( 10 ) and a detachment device ( 50 ).

1 . A device for automatically changing sanding disks, comprising:
 a detaching device ( 50 ) for detaching sanding disks ( 12 ) from sanding disk receptacles ( 100 ), the detaching device ( 50 ) comprises:   a support surface ( 51 ) that has an opening ( 52 ), a diameter of which is greater than a diameter of the sanding disks ( 12 ), and   a separating element ( 53 ) is arranged above the opening.   
     
     
         2 . The device as claimed in  claim 1 , wherein the separating element ( 53 ) has a separating edge ( 54 ) that comprises a point ( 55 ). 
     
     
         3 . The device as claimed in  claim 2 , wherein the point is configured with a V-shape or a W-shape. 
     
     
         4 . The device as claimed in  claim 2 , wherein the separating element ( 53 ) is fastened to the support surface ( 51 ), and a spacer element is provided between the separating element ( 53 ) and the support surface ( 51 ). 
     
     
         5 . The device as claimed in  claim 1 , wherein the separating element ( 53 ) comprises a disk. 
     
     
         6 . The device as claimed in  claim 5 , wherein the disk includes a separating edge with a wall thickness that is less than a distance of a sanding disk from a sanding disk receptacle located beneath the opening. 
     
     
         7 . The device as claimed in  claim 1 , further comprising a container arranged beneath the opening configured to receive the detached sanding disks. 
     
     
         8 . The device as claimed in  claim 1 , wherein the separating element is releasably fastened to the support surface. 
     
     
         9 . The device as claimed in  claim 1 , further comprising a spacer element arranged between the separating element and the support surface, the spacer element is fitted in order to set a distance of the separating element from the support surface. 
     
     
         10 . The device as claimed in  claim 1 , wherein the separating element includes a deflection element configured to detach a sanding disk. 
     
     
         11 . The device as claimed in  claim 1 , wherein the separating element is tiltably mounted. 
     
     
         12 . The device as claimed in  claim 11 , wherein the separating element includes a separating edge or point that in an initial position is located higher than an opposite end of the separating element, and is configured such that upon the sanding disk receptacle reaching the separating edge or point, the separating element tilts to a removal position in which the separating edge is tilted in a direction of the support surface such that a setting angle of the separating element is reduced. 
     
     
         13 . The device as claimed in  claim 12 , wherein the separating edge is configured to come into contact with a rim of the sanding disk as a result of a change in angle, and is adapted to push the sanding disk in a direction of the support surface.
