Definitions

  • the invention relates to a method with the features of introductory part of claim 1.
  • the invention relates to furthermore a device with which the method is carried out with the features of the introductory part of claim 16.
  • Glass panels are cut to the desired size by scratching and breaking Cut to size, which is usually on so-called “glass cutting tables” and these "break tables” assigned to them.
  • the glass panes obtained in this way have very sharp-edged, Burr edges, what for subsequent handling of the glass panes, for example when producing insulating glass panes is disadvantageous.
  • On the one hand there is a risk that the edges of the glass panes break out and on the other there is a not inconsiderable risk that someone will turn to the sharp edges of the glass panes injured by cutting.
  • Those attacking at the edges of the glass panes are also subject Support and means of transport (e.g. conveyor rollers or Conveyor belts) through unprocessed edges of glass panes heavy wear.
  • the invention has for its object a method and a device for trimming the edges of glass panes To provide with which glass panes are processed in this way that their edges are no longer sharp, in particular have no burrs.
  • the method according to the invention can be done in different ways be carried out. So it is possible, for example, one after the other trimming all (four) edges of a glass pane on both sides, why the glass pane after trimming the edges of an edge, for example around a perpendicular to its plane Axis, is rotated until the next edge of the glass pane, the edges of which are to be trimmed in the processing position located.
  • the method according to the invention allows it in one embodiment also several edges of a glass pane at the same time trimmed, especially in rectangular or square Slices is preferred. For example, this is how it worked be that first - for example, essentially vertically standing glass pane - the edges of the in Direction of movement front, vertical edge, then that of upper, horizontal edge, then that of the direction of movement rear, vertical edge and finally the edges of the the lower, horizontal edge of the glass pane.
  • a further acceleration of the trimming of glass panes in the This can reach the area of the edges at their edges be provided that several processing points for trimming become. For example, with two processing points be worked in such a way that in a processing point the edging tool, one after the other, the front, vertical edge and then worked on the rear, vertical edge of the glass pane and in a second processing station with two processing tools, for example, the edges at the same time the upper and lower, horizontal edge of the glass pane be trimmed.
  • a particularly efficient and fast working embodiment the trimming of glass panes according to the invention arises if the procedure is followed such that a (single) processing tool with belt grinders in one first processing point simultaneously in the direction of movement rear, vertical edge of a glass pane and the in Direction of movement front edge of a subsequent glass pane is processed.
  • the first of the two is then preferred Glass panes (i.e. those related to the conveying direction rear, vertical edge has just been machined - you front edge has already been processed) in a second Machining center promoted with two machining tools with belt grinders in a continuous process and in essentially the upper and the lower horizontal Edge of the glass pane is trimmed.
  • the two vertical edges of a glass pane are trimmed, where, for example, one of the processing tools provided for this purpose with belt grinders from bottom to top and the other can move from top to bottom and that afterwards the two horizontal edges, the lower one and the upper horizontal edge of the glass pane at the same time be trimmed in a continuous process.
  • This embodiment too of the method according to the invention can be carried out in two processing stations, with four processing tools with belt grinders be carried out.
  • All embodiments of the method according to the invention are with vertical while machining the edges of the glass panes or essentially vertically aligned glass panes executed.
  • Working with vertically aligned glass panes has the advantage that the inventive method and the intended device without problems in systems for the manufacture of insulating glass panes that are practically exclusively with vertically aligned glass panes, or Insulating glass panes work, can be integrated. It is then namely no longer necessary, the glass panes, their Edges according to the inventive method or in the inventive Device to be trimmed in a horizontal Able to topple over when saving from glass blanks (e.g. compartment trolley) can be removed according to the invention Method or in the device according to the invention to be processed.
  • the trimmed glass panes then no longer in the vertical or essentially be aligned vertically, for example be fed to a glass sheet washing machine. Nevertheless the method according to the invention can also be carried out if the glass panes are aligned horizontally. This can e.g. be beneficial if panes of glass immediately after it cut from glass sheets on a glass cutting machine have been trimmed by the inventive method become.
  • a suitable one for carrying out the method according to the invention Device works with machining tools that are crosswise have arranged belt grinders on both Attack edges of an edge at the same time, around the edges breaking the edges of the glass pane, so trimming and to remove sharp burrs.
