Definitions

  • ABSTRACT A device for use with a flyer coil winder for guiding wire to the coil being wound in either direction of rotation of the flyer and during reversal thereof, the device imparting a cast to the wire as it is wound in a direction to inhibit unwinding of the coil upon relaxation of tension thereon.
  • This invention relates generally to coil winding apparatus of the flyer type, and more particularly to a reversible cast control device for use witha flyer winder.
  • a flyer winder conventionally comprises a member relatively rotatable about a coil form and appropriately located pulleys or other wire guide means for feeding wire to the rotatable member and for guiding the wire to the coil form as the coil is being wound.
  • the wire passing over such pulleys or guide means is subjected to a relatively sharp bend which, due to the memory characteristic of the wire, impart a cast to the wire as it is being wound on the coil form.
  • the cast imparted by the pulleys or wire guide means has been in such a direction that the coil tends to unwind upon severing of the wire forming the coil and consequent release of tension thereon.
  • Flyer winders have been proposed including wire guiding devices for imparting a cast to the wire in a direction to inhibit such unwinding of the coil however, to the best of the present applicants knowledge, such devices have not been reversible, i.e., suitable for use in applications where the direction of flyer rotation must be reversed, i.e., where the flyer winds certain coils in one direction and other coils in the opposite direction.
  • the invention in its broader aspects, provides a reversible cast control device for use with coil winding apparatus which includes a member relatively rotatable about a coil form, the relative rotation being upon a first axis, and means for feeding wire to the member to be wound on coil form.
  • the device of the invention comprises a first pulley rotatably mounted on the member on a second axis spaced outwardly from and normal to the first axis, and second and third pulleys respectively rotatably mounted on the member on second and third axes parallel with the first axis, spaced outwardly from the second axis on the side thereof remote from the first axis, and respectively on opposite sides of a plane including the first axis and the first pulley, the second and third pulleys being respectively closely spaced from opposite sides of the plane.
  • the wire being wound passes partially around the first pulley on the side thereof facing the first axis, outwardly between the second and third pulleys, partially around the trailing one of the second and third pulleys with respect to the direction of relative rotation and on the side thereof remote from the first axis, and thence inwardly to the coil form thereby to wind the coil thereon in the direction of relative rotation.
  • the last bend in the wire prior to winding on the coil form imparted by the respective one of the second and third pulleys is in a direction opposite the winding direction and thus the cast imparted thereby to the wire is in a direction to inhibit unwinding of the resulting coil upon relaxation thereof.
  • a wire crossover guide is provided mounted on the relatively rotatable member adjacent the second and third pulleys on the side thereof remote from the member.
  • the guide has an outer surface including first portions which are respectively substantially flush with peripheral portions of the second and third pulleys in the regions thereof adjacent the points of tangency of the wire therewith as it departs toward the coil form, the outer surface also including an intermediate portion having a smooth, outward curvature extending between the first portions so that upon reversal of the direction of relative rotation, the wire is pulled off of the respective second and third pulley, crosses over the respective first outer surface portion, the intermediate portion and the other first portion, and then engages the other one of the second and third pulleys.
  • Another object of this invention is to provide a reversible cast control device for use with a flyer winder.
  • FIG. I is a side view, partly in cross section and partly broken away, illustrating a flyer winder incorporating the reversible cast control device of the invention
  • FIG. 2 is an end view of the flyer winder of FIG. 1 as viewed generally along the line 2-2 of FIG. 1;
  • FIG. 3 is an enlarged front view of the reversible cast control device of the invention.
  • FIG. 4 is a cross-sectional view taken generally along the line 44 of FIG. 3;
  • FIG. 5 is a cross-sectional view taken generally along the line 5-5 of FIG. 3;
  • FIG. 6 is a top view of the reversible cast control device of the invention as viewed generally along the line 6-6 of FIG. 3.
