Method for controlling principal line at cold side of float glass

Abstract

The invention discloses a method for controlling a principal line at the cold side of float glass, which is characterized in that the running of the glass is tracked by taking a roller bed on the principal line at the cold side of the float glass to serve as a base unit through the running condition of the roller bed by combining with source data of a glass plate firstly entering the first section of roller bed, and the running of the roller bed serving as the base unit is controlled to realize the all-process positioning control of the glass.

Description

technical field [0001] The invention relates to a control method, in particular to a control method for a cold end main line of float glass. Background technique [0002] After the float glass is formed, annealed and cut, finished glass sheets of different specifications and quality grades will be produced. When glass is transported to different locations according to requirements in different specifications or grades, the system must adopt tracking control. Due to well-known reasons, such as glass cutting and breakage, plate drop / sampling inspection in the middle, change settings of different specifications and sizes, speed requirements of the roller table, random start and stop, variable speed actions, etc., will lead to changes in the glass sequence, or single piece / or multi-piece / or group production form changes, changes in the front and rear spacing and position of the board, etc. Board tracking after glass cutting has always been a major challenge in the industry...

AI Technical Summary

Problems solved by technology

[0005] Facts have proved that the above methods have their own advantages and disadvantages, but the fundamental problem is that one depends on the external detection switch, and a problem with the detection switch will cause errors in the entire tracking process; second, it cannot guarantee accurate tracking at any time. features, many accidents cannot be considered on every line

Once the wrong glass is on the shelves, it is difficult to make up for it

The result of leaving the factory with wrong quality information is the economic loss and reputation loss of the manufacturer.
