1444758 Supplying cops automatically to a thread winder NIHON SPINDLE SEIZO KK 14 Aug 1973 [30 Aug 1972 4 Sept 1972 (3) 31 March 1973] 39501/73 Heading D1F A method of automatically supplying cops 10 to a thread winder A comprises supplying the cops from a cop-containing section 1 of a travelling cop-feeder B, through a feed-out section 2 into a cop-charging section 3 beneath the feed-out section 2 in dependence on the presence or absence of a cop in the section 3, and allowing the cops 10 to fall by gravity into a cop-holding magazine 11, in dependence on the presence or absence of a cop in the magazine, from the cop-charging section 3 which has been lowered into a position proximate to the magazine 11 of the winder A, the cops being supplied automatically when the cop-feeder B is stopped in the position registering with the magazine of each winding unit. In operation, the cop-feeder B travels along the front of the winder A in a reciprocatory manner and preferably stops at every alternate winding unit in one direction of travel and at the intermediate winding units in the opposite direction of travel. Suitable means are provided for stopping the feeder B. The cops 10 are moved towards the feeder B on a conveyor belt 61 which has means to lift a portion of the belt in the vicinity of a chute 62 which feeds the cops to the feeder B. The cops are receivd in a channel in the section 1, suitable limit switches SW1, SW2 being provided to effect movement of the belt 61. From the channel in the section 1, the cops are individually transferred to channels 27a 27b in the feed-out section whereby the cops drop into slots in a charging holder 30 in the charging section 3. The charging holder 30 is then lowered into the vicinity of the magazine 11 by lifting means 7, the cops being held in the slots by flaps 33. The flaps 33 are then pivoted and the cops drop into the pockets in the magazine 11. In the event of a cop being present in the pocket, the top of the cop prevents the flap from pivoting and the charging cop is held in the charging holder 30. The charging holder 30 is associated with an arcuate guide 80 and means are provided to entrain the holder 30 with the magazine 11 for rotation therewith during charging of the cops. Suitable electric circuits are described for the sequence of operations.
