Abstract

An electronic system for automatically controlling the weight of glass gobs in a molten glass feeder, through the regulation of the height of the rotatory tube with respect to the feeder orifice; the electronic system includes, in combination, a finished article, a weight detector, a tube position detector attached to said tube, at least a temperature detector and glass level detector at the feeder, each of which respectively providing signals representative of the weight of the finished article, of the height of the tube with respect to the feeder orifice, of the molten glass temperature in said feeder and of the glass level in the same; a data processor which receives and processes the signals of the detectors, in order to compare the weight of the finished articles with a predetermined weight for the same and relates the weight deviations with the temperature and level of the glass and the height of the tube, in order to provide synergistic tube height compensation signals in order to allow an adequate flow of glass to pass between said tube and the feeder orifice and so obtain the predetermined article weight; and an operator panel interconnected with the data processor in order to obtain and provide data therefrom.
