Transverse flat glass snapping method

Abstract

The invention discloses a transverse flat glass snapping method which comprises the following steps: a front conveying roller way of a cross snapping roller is provided with a first optoelectronic switch and a coder, and a rear conveying roller way is sequentially provided with a second optoelectronic switch, a third optoelectronic switch and a fourth optoelectronic switch; when the first optoelectronic switch detects that a whole piece of flat glass comes, the coder begins to calculate the passing distance of the whole piece of flat glass; when the whole piece of flat glass passes through the preset distance, the front conveying roller way and the rear conveying roller way stop, the fourth optoelectronic switch detects that the whole piece of flat glass comes, and the cross snapping roller ascends to snap the whole piece of flat glass into first flat glass and second flat glass; the cross snapping roller descends, and the front conveying roller way and the rear conveying roller way are restarted; when the second flat glass passes through the preset distance, the front conveying roller way and the rear conveying roller way stop, the third optoelectronic switch detects that the second flat glass comes, and the cross snapping roller ascends to snap the second flat glass; the coder is adopted for distance measurement to control the start and the stop of the front conveying roller way and the rear conveying roller way, and in cooperation with the optoelectronic switches, the ascend and the descend of the cross snapping roller are controlled, so that the snapping position is accurate and can be adjusted.

Description

technical field [0001] The invention relates to the technical field of float glass manufacture, in particular to a method for laterally breaking flat glass. Background technique [0002] On-line cutting of float glass production is an important part of the cold-end production process. At present, flat glass is generally broken by horizontal breaking rollers after reaching the branch line. In order to cut into the required size, it must be broken at the corresponding position of the flat glass , the current practice is to use a tracking system to track the position of the flat glass, but the flat glass runs extremely fast on the roller table, and tracking is sometimes very difficult, resulting in breaking errors. Contents of the invention [0003] The object of the present invention is to provide a method for laterally breaking plate glass, which can accurately perform horizontal breaking on the plate glass on the branch line, and the breaking position is accurate, easy to ...
