ANORDNING FOR INRIKTNING AV SKIVOR MED AVSEENDE PA EN REFERENSPUNKT, SERSKILT GLASSKIVOR

摘要

An apparatus for aligning glass sheets moving on a conveyor line prior to shaping on a bending apparatus includes a pair of stops for engaging the leading edge of the glass sheets and a pair of side pushers for engaging the end edges of the glass sheets to align the glass sheets with respect to a reference line. The spacing between the side pushers is automatically selected in accordance with the predetermined sequence of glass sheets. In addition, a sensor detects a mark on the sheets to generate a sequence signal identifying the sheets. The sequence signal is utilized to signal that a sheet is missing or an improper sequence, and/or the signal is utilized to control the means for automatically adjusting the spacing of the side pushers. The stop pins can be adjusted individually in a direction parallel to the reference line and a direction transverse to the reference line. Sensors are provided to detect the alignment of the leading edge of a glass sheet with respect to the reference line and generate an alignment signal. The alignment signal is utilized to position the stop pins along their parallel paths if the glass sheets that are not in the proper alignment.
