Abstract
A delivery system for use for delivering gobs of glass from a plurality of feeder orifices to a plurality of sets of a plurality of blank molds. The blank mold sets are rotated about a central axis with each blank mold of each set being positioned a different radial distance from the axis. The delivery system includes individual gob guiding units each having a lower end positioned over its associated blank mold as each set of blank molds are rotated underneath. The lower end of each unit is moved at a different relative tangential velocity to match the different relative tangential velocity of its associated blank mold. The scoops of the gob guiding units are independently moveable into and out of their feeding positions.
Claims5
A delivery system for delivering gobs of glass from a plurality of feeder orifices to a plurality of sets of a plurality of blank molds, said sets being rotated about a central axis with each said blank mold of each set being positioned a different radial distance from said central axis, said delivery system including a plurality of individual gob guiding units, each one feeding a gob from one orifice to one of the blank molds in a set of blank molds, and means mounting said gob guiding units so that the upper ends thereof are substantially under the orifice and the other ends are positioned over the blank molds as each set of blank molds are rotated underneath and the other end of each unit is moved at a different relative tangential velocity to match the different relative tangential velocity of its associated blank mold.
For use with a glassware forming machine having a plurality of individual sections with each section having a plurality of blank mold cavities, a delivery system for feeding gobs of glass from a feeder having orifices therein to the blank molds, said delivery ststem including a set of scoops, said set having a plurality of scoops equal in number to the number of blank molds for directing gobs of glass from the feeder toward the blank molds of one section at a given time, said scoops of said set each being moveable between an operative position under the orifice for feeding gobs to said blank molds and an inoperative position wherein said scoops are positioned out of feeding relationship with respect to its associated orifice, means for moving each said scoop between its feeding and inoperative positions, said means enabling at least one of said scoops of said set to be positioned in its inoperative position while at least one of said scoops of said set is positioned in its feeding position.
