Abstract
A method and apparatus for controlling the delivery of gobs to each section of a multiple section glassware forming machine to assure that no one section can authorize the delivery of a gob of molten glass to any other section. The invention discloses means for monitoring the time of occurrence within a machine cycle of the delivery enable pulse from each section and for determining whether this delivery enable pulse occurs within a predetermined time window. In the event either the leading or trailing edge of this pulse occur outside predetermined time windows, the gob interceptor associated with the machine is activated to reject the gobs intended for that section. The invention also discloses means for monitoring the motion of a gob interceptor to provide assurance to an operator that the interceptor has moved to either a delivery or intercept position in a timely manner. The time lag between a command to the interceptor and the interceptor's actual arrival at a predetermined position is monitored and it exceeds a predetermined value a command is given to the retract mechanism associated with the gob distributor to retract the distributor to prevent delivery of gobs to all sections of the machine.
