Power failure detection system for a glassware forming machine

摘要

The invention involves a system for detecting power failures in a glass ware forming machine and for effecting either a programmed stop of the machine which permits removal of all molten glass in the machine prior to a shutdown or a more rapid emergency stop. Also a machine speed monitoring system shuts down the machine when the speed slows below a predetermined limit. A supplemental battery system is provided to maintain power during emergencies to permit a sequenced shut down. The programmed control is organized to shut down the elements of the machine to initialized positions.
