Abstract
Apparatus and method for measuring the volume and shape of a falling gob of glass. Two cameras are used to make section by section measurements of the horizontal extent of the moving gob. Timing of the measurements is controlled so as to cause measurements to be made at equal increments of the motion of the gob. The measurements are made 90.degree. apart with respect to the gob and are utilized to determine the volume of each section of the gob. The volumes of the individual sections of the gob are then summed to determine the total volume of the gob. An image of the gob is generated on a television screen to aid in the determination of the shape of the gob.
Claims15
A system for determining the volume of a falling gob of molten glass, comprising:
- glass feeder means for forming and delivering a gob of glass;
- means for measuring, at predetermined increments in the motion of the gob as it falls from said feeder means, the horizontal extent of the gob;
- and
- means for determining, as a function of said predetermined increments and said horizontal extent measurements, the volume of the gob.
A method for determining the volume of a gob of molten glass being delivered from a glass feeder, comprising the steps of:
- severing a gob so as to allow it to fall freely from said glass feeder;
- generating timing signals corresponding to predetermined increments in the motion of the gob;
- successively measuring the horizontal extent of the gob at a plurality of points along its length in response to said timing signals;
- and
- electronically determining, as a function of said horizontal extent measurements and said predetermined increments, the volume of the gob.
