Definitions

  • the invention relates to a method for grinding the peripheral edge surface of a glazing, a glazing and a grinding wheel and a system comprising a glazing and a grinding wheel, each according to the preamble of the respective independent claim.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a possibility for improved retention of a glazing in the arrangement of the peripheral edge surface in a circumferential rubber lip.
  • This object is achieved by a method for grinding the peripheral edge surface of a glazing, a glazing and a grinding wheel and a system comprising a glazing and a grinding wheel, each according to the characterizing part of the respective independent claim.
  • Cartesian and / or polar kinematics can be used.
  • the edge surface of the glazing is guided past the grinding wheel by means of a grinding wheel.
  • the grinding wheel can be arranged stationary and the glass pane can be held by means of suction cups, for example by means of two or more suction cups, which can preferably engage in their central area.
  • the suction cups may also be provided close enough to the outer edges
  • the peripheral edge surface is deflectable due to the suction cups arranged away from the edge surface in a direction orthogonal to the plane of the glazing, so that it can make a certain movement in this direction.
  • the grinding wheel has a peripheral circumferential grinding surface, which is formed mirror-symmetrically such that the outer regions of the grinding surface in rounded or chamfered shape in each case opposite the central region of the grinding surface in the same way outwardly protruding.
  • the distance between the outwardly projecting protruding outer regions of the grinding surface is formed such that the edge surface for grinding in the region between the two previously formed outer regions of the grinding surface is insertable.
  • a displacement of the edge surface of the glazing towards the other protruding outer region of the grinding surface takes place.
  • a grinding wheel is used for grinding, the peripheral grinding surface is additionally provided with at least one provided between its two side edges circumferential projection. This is designed so that this comes at least one circumferential projection only after the self-centering of the edge surface of the glazing by the rounded or beveled shape of the outwardly facing projecting portions of the grinding surface with the edge surface.
  • the edge surface of the glazing is provided with a shape that is so mirror-symmetrical on the one hand with respect to the edge regions, that both the region of the upper circumferential glass edge and the region of the lower circumferential glass edge in a rounded or chamfered shape respectively with respect to the central region formed in the same manner receding in the direction of the center of the glazing, but on the other hand additionally provided with at least one provided between the upper and the lower edge of the glass peripheral groove, said groove at each point along the peripheral edge surface always at the same position of the edge surface, relative to the center of the edge surface, is arranged.
  • the groove is provided in the middle or at a quarter of the width of the edge surface, this is also the case with thickness of the edge surface which fluctuates due to thickness tolerances of the glazing along the entire course of the edge surface.
  • the depth of the at least one groove of the edge surface of the glazing is less than the depth of the rounded edge portions and the height of the at least one protrusion of the abrasive surface is less than the height of the rounded edge portions of the abrasive surface.
  • the geometric dimensions of the edge surface of the glazing and the geometric dimensions of the grinding surface of the grinding wheel are matched to one another such that the at least one circumferential projection of the grinding wheel only after the self-centering of the edge surface of the glazing by the rounded or beveled shape of the outwardly projecting portions the grinding surface with the edge surface in engagement comes.
  • the edge surface of the glazing is centered in relation to the glazing surface of the glazing before the grinding of the at least one groove begins.
  • the relatively uniform position of at least one groove is effected based on the width of the edge surface.
  • Fig. 1 shows the first method step of a method for grinding the peripheral edge surface 1 of a glazing 2 by means of a grinding wheel 3.
  • the edge surface 1 of the glazing 2 is guided past the grinding wheel 3 and / or the grinding wheel 3 is guided past the edge surface 1 of the glazing 2 ,
  • the edge surface 1 in this case has an upper circumferential glass edge 4 and a lower peripheral glass edge 5 in the orientation shown.
  • the grinding wheel 3 in turn has a peripheral circumferential grinding surface 6, which is mirror-symmetrical in such a way that the outer regions 7, 8 of the grinding surface 6 in rounded or bevelled shape in each case with respect to the central region of the grinding surface in the same way in the radial outward direction pointing are formed protruding.
  • the distance between the outwardly protruding outer regions 7, 8 of the grinding surface is greater than the width of the edge surface 1 of the glazing 2, so that the edge surface 1 for grinding in the region between the above-formed outer regions 7, 8 of the grinding surface 6 is insertable.
  • the height of the projection 9 is formed smaller than the height of the rounded or bevelled edge portions 7, 8 of the grinding surface 3, so that the projection 9 only after the self-centering of the edge surface 1 of the glazing 2 by the rounded or beveled shape in the radial Direction outwardly protruding portions 7, 8 of the grinding surface 3 with the edge surface 1 is engaged.
  • the desired contour of the edge surface 1 of the glazing 2 results lateral rounding of the glass edges 5, 6 and a depression 10 located between the glass edges 5, 6 includes.
