ABSTRACT:
An electronic system for automatically controlling the weight and shape of glass gobs in a molten glass feeder. This electronic system continuously monitors the temperature, viscosity and level of the glass at the feeder bowl as well as the rotation and height of the tube with respect to the feeding orifice of the feeder, the reciprocating speed and stroke of the plunger inside the tube, the cutting speed of the glass gob shear blades, the shape of the gobs, and the weight of the finished articles through appropriate detectors which provide representative signals of the parameters that said detectors are respectively monitoring; a data processor that receives the data and processes same so as to compare the weight and form of the finished articles with their predetermined weight and shape and relate weight and shape deviations with the rest of the detected parameters to provide control signals to the tube mechanisms, plunger and shear blades which regulate the rotation speed and tube height, the reciprocation speed and plunger stroke and the shear speed of the blades in order to obtain the desired shape of the gobs and the desired, predetermined weight of the finished articles.
