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.

An electronic system for automatically controlling the weight of the glass gobs in a molten glass feeder of the type which includes, a feeder bowl which has feeder orifice; a rotating tube in the feeder bowl, aligned with the orifice and mounted on a mechanism that controls its rotation and height with respect to the orifice, in order to homogenize the glass in the feeder bowl and regulate the passage of the glass toward the orifice; at least a reciprocating plunger in the tube which is aligned with the orifice and mounted on a reciprocating mechanism which imparts and controls its reciprocating movement in order to push out a predetermined amount of glass toward the orifice; and at least a pair of reciprocating blades placed facing each other underneath the orifice and mounted on a reciprocating mechanism for cutting the glass gobs off the glass flow that comes out from the orificen and wherein the system comprising: a weight detector, a tube position detector coupled to said tube, and a temperature detector and a glass level detector placed at the feeder bowl, all of which provide representative signals of the weight of the finished articles, of the height of the tube with respect to the orifice, of the glass temperature and of the level of the glass in the feeder bowl; a data processor which receives and processes the signals of the detectors in order to compare the weight of the finished articles with the predetermined weight for the same and relate the weight deviations with the temperature, the glass level and the height of the tube, so as to provide height compensation signals to the tube mechanism in order to permit the adequate passage of the glass toward the orifice in order to obtain the predetermined weight for the articles; and an operator panel interconnected with the data processor in order to provide and obtain the information from the same.
