  • Patent number: 6050172
    Abstract: A pneumatically operated mechanism for a glass machine comprises a piston and cylinder device, first and second air lines leading to opposite sides of the piston, and first and second control means for controlling the passage of air through the air lines, which control means each comprise an operating valve and a speed control valve. The valves are solenoid operated and by control of the timing of operation of the valves the speed of movement of the piston and the degree of cushioning at the ends of its stroke may be adjusted. In a modified mechanism pressure sensors which sense the pressures in the piston and cylinder device are connected to a processor which is adapted in response to data sensed by the sensors to operate the valves to obtain a desired movement of the piston.

  • Patent number: 6032493
    Abstract: An H-28 machine has a plurality of identical sections each processing a gob of molten glass into a parison and then into a piece of ware each complete revolution of the section. Each section includes a blank mold displaceable between a parison forming position and a retracted position by blank mold down air.Each section also includes a plunger which is displaceable from an elevated position down to the parison forming position and a neck ring assembly which includes an air motor. Finally the section also includes a blow mold displaceable from a remote position to a closed position. The air motor is operated from the time that the blank mold begins its displacement from the parison forming position to the retracted position by a valve which connects blank mold down air to the air motor.

  • Patent number: 6009727
    Abstract: Opposed mold supports of a mold opening and closing mechanism are driven by electronic motors between retracted and advanced positions. The motors are electronically geared together and follow a feed program which initially advances the associated mold supports a set distance which is half the separation distance. When the displacement of both supports stops, both motors are operated at a slow velocity. When it is determined again that both supports have stopped, the location of each is verified to be within an acceptable range and each motor is then operated to apply a desired clamping load.
