Abstract
1363913 Winding armatures; shearing POSSIS MACHINE CORP 15 June 1971 27983/71 Headings B3A and B3W In a method and machine for winding coils of wire on to armature cores successively presented to the machine wire gripping means are actuable to grip a stretch of wire leading from a conventional flyer to a core which has just been wound and wire cutting means adjacent the gripping means sever the wire, while it is gripped, between the gripping means and the core, the gripping means holding the end of the wire ready for the winding of the next coil. As shown, Fig. 1, a core 17 is gripped by chucks 32, 33 mounted on housings 22, 23 which are movable to vary the spacing between them by, e.g. an air cylinder. The housings also support conventional flyers 38, 39. Cylinders 27, 28 power mechanism for indexing the core to bring successive pairs of armature slots to coil-winding position. Associated with each flyer, and within its orbit around the core is a wire gripper/cutter device 49, 52. Each device, Fig. 9, comprises a groove 59A in which wire is placed at the start of winding and held by an air actuated gripper 68. The first winding movement of the flyer forces the wire into a holder 79 displacing a spring-loaded latch 85 which then retains the wire aligned with the slots on which it is to be wound. After winding has started, the gripper is retracted briefly to release the end of the starting lead. When the last coils have been wound, the gripper is retracted again to allow the ending lead to drop into the groove 59A. A cutter 63 is connected to the gripper 68 by a lost motion device 71-74 so that actuation of a motor 76 causes the gripper 68 to clamp the wire 43 against the face 59 of the groove 59A and the cutter 63 to shear it against the edge of the body 57 of the gripper/ cutter nearest the core. The lead thus remains clamped by the gripper 68 until the fresh core is ready to be wound. An alternative embodiment, Figs. 12-14, is for winding an armature core A.C. which includes a commutator C with tangs T. A combined core-gripping and -rotating unit 104 includes a tubular shield 119 which is movable between an operative position in which it shields the tangs T and a position in which a pair of tangs are exposed at diametrically opposed notches 118 in a tube 116. A tube 124 between a conventional core-gripping collet 106 and the tube 116 is tapered at its free end, Fig. 14, to enter the hooked tangs T and retain a lead looped around one of the tangs. The tube 124 is moved to lead-retaining position by a fluid cylinder 120 and returned by a spring 125. Associated with each conventional flyer 100 is a gripper finger 130 which is movable between an outermost position, Fig. 12, and a position adjacent the tubular shield 119, Fig. 16, by cylinders 132. In operation, wire inserted in a notch 135 in the finger or left there after the winding of a preceding coil is held in the notch 135 by a reciprocable plunger 138. The finger 30 is adjacent the shield 119 which is in its operative position. The first winding movement of the flyer carries the wire to the Fig. 16 position, the shield 119 and tube 124 are retracted and the flyer is moved in the reverse orbit to hook the wire around the exposed tang T. The shield and tube are advanced to operative position and the flyer is again moved in winding orbit to form an α-type loop around the tang (Fig. 19, not shown). The core is then rotated to the position in which the first coils are to be wound which tensions the wire held by gripper finger 130 and forces it into a notch 127, Fig. 14, of a hook 126 on the shield 119. The shield is retracted shearing the wire between the edge of the notch 127 and the edge of the tube 116. The ending lead is looped around a tang and sheared in similar fashion when winding of the core is complete. The gripper retains the starting lead until just before the ending lead is to be severed. In a modification of this embodiment, Fig. 26, each wire cutter 150 comprises a tube 157 with a wire-receiving notch through which a cutter 159 moves to shear the wire. The wire cutter and its associated wire gripper 152 are movable as a unit by means of a cylinder (164) Fig. 25 (not shown) and the gripper is movable relative to the cutter to tension the wire for shearing by a cylinder 168.
