Method for automatic path control of a peripheral-edge-grinding machine for glass panes and device for implementing the method

摘要

The invention relates to a method for path control of the grinding head (10) of a peripheral-edge-grinding machine for glass panes, in which the grinding head (10) is arranged on an X-Y cross-slide (4), whose displacement is controlled according to a programme. The path control of the cross-slide (4) is carried out by means of a sensor member (15) which is articulated on the cross-slide (4) and which runs ahead of the grinding head (10) by a defined length while sensing the edge of the glass pane and establishes the values for the X and Y coordinates. The values thus established are stored in a biaxial shift register and are used, after the shift register has been scanned, for controlling the servomotors for the cross-slide (4). <IMAGE>
