Automatic and on-line method for weighing and measuring thickness of plate glass

Abstract

The invention discloses an automatic and on-line method for weighing and measuring thickness of plate glass. The automatic and on-line method comprises the following steps of arranging a parallel beamweighing sensor between a glass split table support rack and a glass split table; arranging three upper measurement air cylinders, and connecting the three upper measurement air cylinders to an upperdisplacement sensor; arranging three lower measurement air cylinders, and connecting the three lower measurement air cylinders to a lower displacement sensor; controlling a glass split table supportair cylinder to ascend by a glass production line PLC when glass runs at the glass split table so that the glass is raised from a transmission roller; sending acquired weight data to the glass production line PLC by the parallel beam weighing sensor, subtracting weight of the split table from the weight data to obtain glass weight by the glass production line PLC; and controlling the three upper measurement air cylinders to descend and simultaneously controlling the three lower measurement air cylinders to ascend by the glass production line PLC, and performing calculation to obtain glass thickness of a measurement point by the glass production line PLC according to displacement data fed back by a displacement sensor. By the automatic and on-line method, the working efficiency is improved,the labor cost is reduced, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to an online automatic weighing and thickness measurement method for flat glass. Background technique [0002] In the production process of flat glass, the production efficiency and quality of the original glass are the key to the success of the production line. The thickness variation, that is, the difference between the thickest and thinnest points of the same substrate glass within the required range (also called thickness difference) is an important indicator of quality. [0003] At present, the measurement of the thickness of the substrate glass is generally carried out in an off-line manner, and the manual measurement is performed using a micrometer. This measurement method requires a lot of manpower, low efficiency, low detection frequency, resulting in a lag in process adjustment, which seriously affects the yield rate and production efficiency of the production li...
