Definitions

  • the invention relates to a method for re-sharpening (grinding) of grinding wheels and an arrangement with which the method can be carried out.
  • the problem is that the tool (the grinding wheel) wears off when it is used for grinding, so that the result of the grinding, in particular the shape of the edged edges of glass sheets, is not constant, but changes undesirably.
  • the invention has for its object to provide a method and an apparatus of the type mentioned are available, which does not have the disadvantages described.
  • the grinding tool (grinding wheel) can also be sharpened during use of the grinding wheel for grinding workpieces, in particular for trimming the edges of glass sheets, there are no production stoppages for the sharpening process (straightening process) of the grinding tools (grinding wheels) and the shape and quality of the workpieces obtained after grinding, in particular the edges of glass sheets which have been trimmed, remain the same.
  • the resharpening can be carried out continuously at specific, predetermined time intervals or else.
  • the grinding tool is assigned a tool for sharpening the same, which acts on the grinding tool at a location which is spaced from the point at which the grinding tool acts on the workpiece.
  • the tool used for re-sharpening can be a stationary or a rotating tool.
  • an application of the invention is to resharpen grinding wheels having grooves such as are used for trimming glass sheets at their edges.
  • the re-sharpening tool has a contour corresponding to the desired contour of the edged edge of the glass sheet.
  • the grinding tool is equipped with diamond as an abrasive material, it is preferred if the tool contains re-sharpening as an abrasive material corundum. It is understood that, as is common practice in grinding, the sharpening of the abrasive tool is performed while adding a liquid which cools and abrades (scours away) abraded material.
  • Fig. 1 shows schematically an arrangement for carrying out the method according to the invention in side view
  • the grinding tool is a grinding wheel 1, which has an annular groove 3, with which the edge 5 of a glass sheet 7 is trimmed, so that the edge 5 then has a rounded, for example approximately semicircular, cross-section.
  • the grinding wheel 1 is rotated by a drive, not shown, wherein the direction of rotation (arrow 9) of the relative movement between the glass sheet 7 and grinding tool 1 is directed opposite, as indicated in Fig. 1 by the arrows 9 and 11.
  • a tool 21 (the irregular outline shape of the tool 21 shown in the drawing is only a drawing technical measure, the tool 21 is "demolished” shown) is assigned for resharpening.
  • This tool 21 for re-sharpening is formed, for example, as a stationary tool which is pressed in the direction of the arrow 23 in the groove 3 of the grinding wheel 1.
  • the sharpening tool 21 may consist of corundum or be equipped with corundum as an abrasive material.
  • the outline shape of the tool 21 may be circular or polygonal, eg octagonal.
  • the resharpening tool 21 has at least one section which is curved with the same radius as the effective surface of the grinding wheel 1 (in the example the groove 3) and has a contour corresponding to the contour, which should have the edge 5 of the glass sheet 7 after trimming.
  • the tool 21 for re-sharpening the grinding wheel 1 is arranged in the region of the grinding wheel 1 which moves away from the workpiece 7, and not in the region which faces the workpiece 7 moving towards.
  • the tool 21 of the half 2 is associated with the grinding wheel 1, which moves away from the engagement point 13 of the grinding wheel (1) on the workpiece (glass panel 7).
  • This has the advantage that the cooling and rinsing liquid applied for trimming the glass panel 7 is also available to a sufficient extent for re-sharpening, so that in many applications a separate application of cooling and rinsing liquid for re-sharpening is not required.
  • the attack of the tool 21 on the grinding wheel 1 can be permanent or the tool 21 is brought in predetermined and adjustable intervals in engagement with the grinding wheel 1, to sharpen this.
  • a grinding tool in particular a grinding wheel 1, which is provided for trimming the edges 5 of a glass sheet 7, the grinding wheel 1 is associated with a re-sharpening tool 21 which operates continuously or intermittently during operation of the grinding wheel 1 in order to edge edges 5 is to the grinding wheel 1, resharpen. So production stoppages for resharpening are not required and it is a constantly consistent quality of the result of the grinding work (edged edge 5 of a glass sheet 7) guaranteed.

Abstract

L'invention vise à réaffûter un outil d'aiguisage, notamment une meule (1) destinée à l'affilage des arêtes (5) d'une plaque de verre (7). A cet effet, à la meule (1) est associé un outil d'affûtage (21) qui, pendant que la meule (1) est en service pour affiler des arêtes (5), agit en permanence ou par intermittence pour réaffûter la meule (1). Ainsi, il n'est pas nécessaire d'interrompre la production pour le réaffûtage et on obtient une qualité continue du travail de meulage (arête (5) affilée d'une plaque de verre (7)).
