  • the fingers and needles are radially adjustable toward the center of the core in preparation for subsequent winding.
  • the wire supply is supported on a turntable positioned to rotate as the wire is withdrawn to prevent twisting during rotatable indexing of the head.
  • the present invention pertains to apparatus for winding coils with a wave form pattern into the slots of cores of electrical devices such as into the slots of stators for alternators, electric motors or generators.
  • a completed motor comprises a series of such coils wound in a pattern depending upon the type of motor, the wire feeding head being alternately indexed in opposite directions in order to form the coil end loops of conventional winding.
  • Wave form winding differs in that the wire progresses from slot to slot circumferentially around the core in a serpentine path, the completed winding consisting ofseveral layers of this serpentine type winding, Wave form winding is advantageous in that it provides for better heat dissipation in use.
  • Coil winding machines for winding coils in the conventional manner are disclosed in Frederick US. Pat. Nos. 3,082,966 and 3,227,382. If it were attempted to wind wave form coils by machines of the type shown in the above patents the wires would tend to concentrate on the sides of the slots in the core and would not build up from the bottoms of the slots toward the center of the core in a proper pattern to obtain efficient wave form winding. Therefore, winding machines as hereto-' fore proposed have not been suitable for wave form winding.
  • the present invention provides apparatus for winding coils with a wave form pattern which includes a wire feeding rotatably indexible head mounted for reciprocation axially of the core, the head having wire laying needles adjustably carried therein to provide for radial adjustment toward the center of the core as the winding progresses, and there being guiding fingers over which the wires are guided as the head is indexed which are also radially adjustable toward the center of the core.
  • a wire feeding rotatably indexible head mounted for reciprocation axially of the core, the head having wire laying needles adjustably carried therein to provide for radial adjustment toward the center of the core as the winding progresses, and there being guiding fingers over which the wires are guided as the head is indexed which are also radially adjustable toward the center of the core.
  • retainer means for holding previously wound sequences of wires toward the bases of the core slots as additional sequences are being wound, and there is means for preventing twisting of the individual wires as they are fed to the machine.
  • a general object of the invention is to provide apparatus for efficiently winding coils with a wave form pattern.
  • a further object of the invention is to provide apparatus for winding coils with a wave form pattern wherein the head has a set of circumferentially spaced needles, such as three, which act to lay a plurality of strands simultaneously in different slots in a serpentine pattern.
  • a further object of the invention is to provide, inapparatus as above described, means for insuring that the wound sequences of wire start at the bases of the slots and progress toward the center of the core as the winding progresses to insure efficient filling of the slots.
  • a more specific object of the invention is to provide apparatus as above described in which the wire laying needles and wire holding fingers are radially adjustable toward the center of the core.
  • a further object of the invention is to provide, in a coil winding apparatus, movably mounted retainer means movable to positions to maintain previously wound sequences of wire toward the bases of the core slots as additional sequences are being wound.
  • a further object of the invention is to provide, in an apparatus as above described, turntable means for supporting the wire supply in a manner to compensate for the rotatable indexing movement of the needle head. and to prevent twisting of the wire as it is being withdrawn for use.
  • a further object of the invention is to provide, in an apparatus as above described, an improved arrangement wherein the wire guiding fingers are supported over circumferentially spaced lands between slots, and wherein the fingers on one side of the core are staggered with respect to the fingers on the other side, whereby efficient wave form winding is accomplished.

  • FIG. 8 shows the retainer ring 36 holding the first sequence while wire is being laid for another sequence
  • FIG. 9 shows the wires at the start of the first turn of the second sequence after the head has been indexed.
  • the rotatable indexing of the head In winding, as the wires are pulled off of the spools 51, the rotatable indexing of the head, always in the same direction during the wave form winding, would normally cause objectionable twisting of the three wires.
  • the turntable By having the spools 51 mounted on a turntable which is driven in sequence with the head 57 at the same speed the turntable will rotate as the head 57 is being indexed, and the rotation of the turntable will compensate for the rotation of the head and prevent the objectionable twisting.
  • This desirable feature is accomplished by having the turntable 52 rotate at a 1:1 ratio with the head 57 in order to unwrap wire automatically from the spools 51 at a rate which is in sympathy with the rotation of the head 57 when the latter is rotatably indexed.
  • wire holding elements are portions of an annular angularly, inwardly projecting flange and are separated by peripherally spaced slots which are located to accommodate the guiding fingers when the retainer means is in a retaining position.

  • the retainer means is a' ring, in which said ring has an angularly, inwardly projecting annular flange with a circle of holding elements positioned to engage the looped ends of wound sequences of wire to maintain said sequences toward the bases of the core slots while additional sequences are being wound, in which said guiding fingers have hooked ends positioned over the lands between slots of the core, and in which there are circumferentially spaced recesses between said holding elements which are positioned to allow the hooked ends of the guiding fingers to project therethrough when the retainer means is in retaining position, the recesses of the retainer ring at one end being staggered with respect to the recesses of the retainer ring on the other end.
  • tubular wire laying needles means mounting said needles for radial adjustment in the periphery of said head for movement from a position in which the wire is laid close to the bases of the slots of the core to positions progressively closer to the center of the core, guiding fingers, means mounting said fingers for radial movement on the core-supporting means whereby they may be adjusted to conform to the position of the needles and thereby provide for progressive winding of wire sequences from the bases of the slots toward the open ends thereof, a tubular spindle, means mounting the 3,787,000 9 10 head on said tubular spindle, a rotatably supported and prevent twisting of the wire.
