ABSTRACT:
Improved system for controlling the movement of rotary article conveying mechanism in IS glassware forming machines employing a reversing arm, operating mechanism for said arm to move same between a parison forming station and a blow molding station, said operating mechanism including a double action fluid driven actuator, solenoid controlled valves for the actuator, an arm position sensor, an actuator pressure sensor, a logic circuit receiving signals from the sensors, a digital valve responsive to signals from the logic circuit for fluid flow control from the actuator, a regulator controlling fluid pressure to the actuator, and a control panel containing digital indicators, mode switches and a mode indicator and a digital display for reception and transmission of signals to and from the logic circuit, the end result being the precise timing of reversing arm operation and elimination of impact at the end of reversing arm movement, with identical operational mechanism for the take-out arm, with the additional anti-shock safeguard by means of a pressure controlled damper set to a predetermined pressure to control the actuator upon failure of the normal actuator controlling elements.
