1,158,707. Feeding cops to, and donning cops in winding machines. MURATA MACHINERY CO. Ltd. 17 Oct., 1966 [20 Oct., 1965; 27 Nov., 1965; 22 Feb., 1966], No. 46410/66. Headings D1F and D1J. An automatic method for supplying cops to an automatic winding machine comprising feeding cops 3 in containers 4 to a point c where the cops are individually transferred to cop carriers 58 which move along an endless path, retrieving a yarn end from each cop along the path and joining it to the yarn end of a package being wound on a winding station 5, and feeding each cop to the appropriate winding station. The cop containers 4 transferred from a spinning machine by a conveyor pass along conduit 40 to rotating disc 12 which feeds the containers to a pair of vertically spaced horizontal plates 32 which have four grooves 31 spaced around their periphery. The cop carriers 58 are mounted on top and bottom rails and are driven through a friction drive by belt 56. Plates 32 are also driven through a friction drive. Both drives are set in operation by the passage of a winding station 5. Both the plates 32 and carriers 58 are normally prevented from moving by stoppers. Solenoids actuated by the passage of a winding station momentarily retract the stoppers so that an empty cop carrier 58 moves into the position below point c while plates 32 move through a quarter turn so that a cop container in a groove 31 moves to point c. At point c a cop falls through a chute into the carrier 58. The empty containers 4 are passed along a conduit 41 to a conveyor which returns the containers to a spinning machine. At position h the top of each cop is guided between a pair of rotating rollers which have radially projecting blades of polyurethane resin which loosen a tip bunch wound at the top of each cop. The loosening may be assisted by rotating the cop by a belt. The loosened yarn end is sucked into pipe 124. The bottom rail adjacent pulley 50 is obliquely positioned to cause the carriers 58 to become inclined and be aligned in position i with the cop mounting peg of a winding station 5. At position i a stopper prevents movement of a carrier till a winding station is positioned opposite threto. At position the two yarn ends are knotted together, while at position k the cam rail holding the trap door of the carrier shut is inclined away front the bottom of the carrier allowing the door to open and the cop to fall onto the peg. |
