Abstract
There is disclosed a system for delivering gobs to a plural section glass forming machine in which an oscillating scoop distributes the gobs not only to the machine sections but also, on command to the servo motor drive for the scoop, to a delivery trough extending to a cullet chute. The chute may be behind the machine or in front. When it is desired to reject gobs from a section, the command is given to the motor control, which will index the scoop to the reject position instead of to the section so that it may be taken out of service.
Claims6
In apparatus for delivering gobs to plural sections of a glass forming machine wherein gob distributing scoops are positioned with their upper ends in alignment with feeder orifices of a glass gob feeder with means for oscillating said scoops about the axes of the feeder orifices to deliver gobs to a plurality of set of troughs each leading to one of a plurality of machine sections positioned therebelow, the improvement comprising a pair of deflector chutes extending from the path of sweep of the delivery end of said scoops to a cullet chute and means connected to said means for oscillating said scoops for selectively moving said scoops into alignment with said deflector chutes to reject gobs in sequence away from a selected machine section upon command.
In apparatus for distributing plural gobs to a series of glass forming machine sections positioned in a row therebelow, wherein the gob distributor comprises a set of oscillatable scoops whose upper ends are in alignment with the feeder orifices and their lower ends move through an arc and are indexed into alignment with plural sets of throughs extending to the forming machine sections, the improvement therein comprising a servo motor connected to drive the scoops in a preselected sequence to deliver the gobs to the sections in a predetermined order, a cullet chute adjacent said forming machine sections, a set of deflector chutes in addition to said plural sets of troughs, said deflector chutes extending from the arc of the scoops' lower end to said cullet chute and positioned with said scoop upper ends at the middle of the arc of said scoops' lower ends whereby gobs to be rejected are intercepted by the scoops when positioned in alignment with said deflector chutes.
