ABSTRACT:
A method is disclosed for automatically doffing a full strand package on a collet winder such as used in the manufacturing of fiberglass and the like strands. The method includes providing a rotating doffing cup (A) which includes a cylindrical cup (40) having an inflatable liner (44) carried on the inside of the cup. A robotic vehicle (10) includes a servo-linkage arm (28) which positions the doffing cup at a desired winding station along a row (14) of collet winders (B). The method includes bringing the doffing cup up to an approach position, pivoting a traverse guide (76) away from the collet, and extending the doffing cup over a full strand package (36). The rotating cup is brought up to a speed slightly greated than the speed of the rotating yarn package. The liner (44) is then inflated causing the rotating doffing cup to grip the strand. The rotating cup (A) is then retracted with the strand package. A length of strand (90) extends from the doffed yarn package (91) to auxiliary windings (88) formed on the collet from the strand (74) being previously pushed off the strand package. During retraction, the strand (90) breaks. The doffed strand package is then placed on a carrier (34) at a receiver station (32) which conveys the full strand packages to a next processing station.
