Abstract
A rectangular glass workpiece positioning system and method of use for a cutting table is disclosed. A conveyor transports a rectangular glass workpiece in a transporting direction. A stop mechanism is adapted to abut an edge of the glass workpiece which is positioned substantially perpendicular to the transporting direction of the conveyor. A movable edge sensor is adapted to sense an edge of the glass workpiece extending substantially parallel to the transporting direction with the movable edge sensor movable at least perpendicular to the transporting direction. A movable cutting head is provided for cutting the glass workpiece according to a predetermined pattern. The present invention additionally includes a method of retrofitting existing cutting tables.
Claims14
A glass workpiece cutting table comprising:
- a conveyor transporting and supporting a glass workpiece in a transporting direction;
- a stop mechanism adapted to abut an edge of the glass workpiece which is positioned to extend substantially perpendicular to said transporting direction of said conveyor, wherein said conveyor transports the glass workpiece in said transporting direction until the glass workpiece engages said stop mechanism;
- a movable electronic edge sensor adapted to sense an edge of the glass workpiece extending substantially parallel to said transporting direction without physically contacting the glass workpiece, said movabl edge sensor movable at least perpendicular to said transporting direction;
- a movable cutting head for cutting of the glass workpiece according to a predetermined pattern, the predetermined pattern not limited to a profile of the glass workpiece;
- and
- a controller coupled to said edge sensor for controlling movement of said cutting head, wherein said controller is adapted to determined a position of the glass workpiece, relative to said conveyor of said cutting table based upon a sensing of an edge of the glass workpiece by said edge sensor, and wherein said controller controls movement of said cutting head relative to said conveyor of said cutting table based upon said predetermined pattern.
A glass workpiece positioning system for positioning rectangular glass workpieces, said positioning system comprising:
- a conveyor for receiving, transporting and supporting the rectangle glass workpiece in a transporting direction;
- a stop mechanism adapted to abut an edge of the rectangular glass workpiece which is positioned to extend substantially perpendicular to said transporting direction of said conveyor, wherein said conveyor transports the rectangular glass workpiece in said transporting direction until the rectangular glass workpiece engages said stop mechanism;
- a movable electronic edge sensor adapted to sense an edge of the rectangular glass workpiece extending substantially parallel to said transporting direction, said movable electronic edge sensor movable at least perpendicular to said transporting direction without physically contacting the glass workpiece;
- and
- a control means coupled to said edge sensor adapted to determine a position of the glass workpiece relative to said conveyor based upon a sensing of the edge of the glass workpiece by said edge sensor.
A method of positioning a glass workpiece on a cutting table comprising the steps of:
- a) receiving and transporting a glass workpiece in a transporting direction;
- b) abutting a first edge of said glass workpiece which is positioned substantially perpendicular to said transporting direction;
- c) moving an electronic edge sensor substantially perpendicular to said transporting direction;
- d) sensing an edge of said glass workpiece which is substantially parallel to said transporting direction without physically contacting the glass workpiece;
- and
- e) determining a position of the glass workpiece relative to the cutting table based on a sensing of the edge of the glass workpiece by said edge sensor, wherein determining the position of the glass workpiece is used to adjust automatic processing of the glass workpiece on the cutting table.
