ELECTRONIC GLASS SUPPLY PLUNGER OPERATION MECHANISM

Japanese Patent JPS6212618

A

A glass feeder plunger operating mechanism driven by an electric motor controlled by a programmable computer programmed to drive the motor in a predetermined manner in order to generate a predetermined motion profile of one or more glass feeder plungers. The plungers are secured to the end of a cantilevered lateral support bracket which is cyclically and vertically reciprocated by cyclical oscillations of the electric motor. The output shaft of the motor is connected to a ball screw in threaded engagement with a ball nut which is secured to a member connected to the plunger support bracket. The plunger support bracket is attached to a moveable vertical support shaft which maintains plunger alignment during the range of motion. The operating mechanism is attached to a frame which is adjustable in two dimensions to facilitate alignment of the plungers with their respective orifices. Air cylinders are provided to counter-balance the weight of the members being vertically reciprocated. Overload means is provided to limit plunger damage in the event excessive operating forces are encountered. Various sensor switches and adjusting means are disclosed to facilitate plunger alignment and control.
