Device and method for severing a continuous glass strip

摘要

The invention relates to a method and a device for severing a marked region of a glass strip (1) produced continuously on a conveyor belt (11), having the following characteristics: a) a line (12) highlighting the severing of the marked region is scored on the continuous glass strip (1), b) once the scored line (12) reaches the crusher roll (6), the two lock rolls (7, 8) following the crusher roll (6) are folded away downward, c) once the scored line (12) is located in the region of the highest area of the crusher roll (6), means for shearing off (5) push onto the glass strip (1) and break it off, d) after the broken-off glass piece (10) has dropped, the lock rolls (7, 8, 9) are folded back in the conveyor belt (11), and to a computer program and a machine-readable carrier with the program code thereof.

主权项

1. A device for severing a designated region of a glass ribbon (1) produced continuously on a conveyor belt (11), said device comprising:
a marking device (3) for scoring a line (12) on the continuous glass ribbon which marks the severing location for the designated region of the glass ribbon (1); a crusher roller (6) positioned forward of the marking device; at least one moveable lock roller positioned forward of the crusher roller and moveable between a folded up position and a folded away position; a free space between the crusher roller and the at least one moveable lock roller wherein a part (10) can fall through the free space when the at least one moveable lock roller is in the folded away position; a shearing-off tool (5) positioned above the free space; and a control unit in operable communication with the shearing-off tool; wherein all positions are in relation to the running direction of the conveyor belt; wherein the control unit controls movement of the shearing-off tool between a starting position above a plane of the conveyor belt (11) at the crusher roller (6) and a lowered position at or below the plane to break off a part (10) of the glass ribbon (1) by pressing from above onto the part (10) that protrudes freely past the crusher roller when the scored line (12) is located in the region of the highest point of the crusher roller (6); and wherein the at least one moveable lock roller comprises a front lock roller (7) and a rear lock roller (8) and at least one of the front and rear lock rollers is moveable downward to the folded away position when the scored line (12) on the continuous glass ribbon reaches the crusher roller (6) and return to the folded up position after the glass piece (10) which is broken off has dropped through the free space.
