Definitions

  • the invention relates to wire machinery, and more specifically to an • Outside-in" double twist bow buncher for simultaneously twisting two sets of wires or strands and winding each set onto one of two bobbins arranged in the machine.
  • Double twist bunchers Machines sometimes denominated as stranders, bow stranders, twisters, double twist twister, pairing machines, double twist stranders, twinners, cablers, bunchers, and double twist bunchers have been in existence for over thirty years. Subsequently referred to as "double twist bunchers", these machines are used to combine a plurality of individual strands of wires and bunch them together by imparting a double twist to them.
  • the individual strands or wires are payed off a plurality of bobbins and directed to the input end at one axial end of the machine. ' The wires are all grouped or bunched together at a closing point prior to the entry of the machine. The wires are all grouped or bunched together at a closing point prior to the entry of the machine. The closing point remains fixed relative to the main structure of the machine. The bunched wires or strands are then
  • a second twist is imparted to the wire between the last sheave mounted on the bow and the first sheave attached to the cradle. Additional pulleys disposed within the space defined by the rotating bow, guide the now double twisted bunched wires to the stationary bobbin supported within the machine and wound on the bobbin while being evenly distributed thereon. Depending on the machine, slightly different wire guiding system arrangements have been used.
  • Double twist bunchers have been extensively used in the electrical wire and cable, steel tire cord and steel rope industries for decades.
  • wires or strands from an external multiple pay-off are guided into the machine, twisted and laid on a bobbin disposed inside the strander ("outside-in” machine).
  • multiple bobbins are arranged inside the buncher which form a multiple pay-off, and ' the wires or strands are drawn off the bobbins, twisted and wound onto an external bobbin ("inside-out” machine).
  • Typical machines are illustrated in the Electrical Wire and Cable Machinery brochure, published by Ceeco Machinery Manufacturing Co., Inc., the assignee of the subject application.
  • Other exemplary structures of existing machines are disclosed in U.S. patent Nos. '3,570,234 and 3,732,682.
  • the other bow is generally provided only to balance the wire-carrying or operative bow. Aside from the dynamic balancing of the system, the non-operative bow has not, up to now, been used for any other function or purpose.
  • a twin bobbin double twist buncher in accordance with the present invention includes inlet guide means at each axial end of a bow strander or twister which accepts another group of wires or strands.
  • Each group of wires or strands are twisted by another one of two wire carrier means in the nature of bows and subsequently wound onto one of two reels disposed or supported within the machine. This is not to say that both sets of wires cannot be run on the same bow. it is simply convenient to use the idle bow provided on many conventional bow-type machines for this purpose.
  • the axes of the two bobbins or reels may be oriented in any position relative to the axis of the twister.
  • the most common configurations include the orientation where the axis of both bobbins or reels are coaxial with the axis of the machine or alternatively, perpendicular to the axis of the machine. In either case, an individual traverse or a common .traverse may be used to distribute the bunched wires or strands across the surface of the reel or bobbin.

  • FIG. 2 is a side elevational view of the operative components within the double twist buncher showing the details of one presently preferred embodiment
  • FIG. 3 is a top plan view of the apparatus shown in FIG. 2, with the bows and bearings removed;
  • FIG. 4 is a top plan view of the double twist buncher shown in FIG. 1;

  • FIG. 1 one presently preferred embodiment of a double twist buncher in accordance with the present invention is designated by the reference numeral 10.
  • Such machines are sometimes referred to as stranders, bow stranders, twisters, double twist twisters, pairing machines, double twist stranders, twinners, cablers, bunchers, and double twist bunchers « While the term “double twist buncher” will be used herein, the machine may also accurately be referred to by one of the aforementioned terms.

  • the double twist buncher 1.0 may be provided with a conventional cover 14 to prevent accidental injury or damage while the machine is in operation, as well as to reduce the noise level.
  • a multiple pay-off 16 which provides a group or bunch of wires or strands 18 which are to be twisted about each other.
  • the wires or strands may cooperate with a conventional line speed sensor and/or measuring wheel 20 and subsequently directed to a lay plate closing point apparatus or to a pulley or sheave 22 which is arranged to guide the bunch 18 along the longitudinal axis 24 of the double twist buncher.
  • the bunch of wires or strands 18 are guided through a first bow 26 and, as will be more fully described hereafter, is wound onto a first reel 28 after the wires or strands have been imparted a double twist.
  • a second multiple pay-off 30 is disposed at the other end of the machine, to the right as viewed in FIG. 1, which, with the pulleys 31 and 31*, directs a second group or bunch of wires or strands 32 into the double twist buncher along its longitudinal axis.
  • the second bunch 32 is imparted a double twist by the bow 34 and subsequently wound onto a second reel 36.
  • the double twist buncher 10 in accordance with the invention accepts multiple wire pay-offs at both longitudinal or axial ends thereof, twists both sets of wires by guiding these wires through another one of the two diametrically opposite bows, and lays each of the twisted sts on one of two reels or bobbins disposed within the machine.
  • the idle bow is the preferred embodiment, the same bow could be used, as to be more fully described in connection with FIGS. 6 -and 7. It is simply convenient to use the idle bow for this purpose.

  • Pintle adjusting arms 82b are used to extend the moveable shafts 82a into or retract said shafts from the bores of the pintles when the bobbins are initially introduced into the cradle and subsequently withdrawn therefrom.
  • Each pintle shaft 80 is coupled to a reel driving gear 84, which is externally toothed, the reel driving gears 84 for each of the reels 28 and 36 being meshingly coupled to a gear 86 which is rotatably mounted, by suitable bearing means, on the cradle 74.
  • the idler wheel 88 and, therefore, the gear 86 are rotated by means of a drive belt 90 which is driven by a DC motor 91.
  • Each of the reel driving gears 84 are also, by means of timing belts 92, used to drive the traverse mechanisms 52.

  • the outlet guide pulleys 48a bring the set of wires onto the second reel or bobbin 36 by way of a traverse mechanism 52 similar to the one used for the bobbin 28.
  • Activation of the motor 70 for the bows causes the bows to rotate which results in rotation of the slip rings 94, 96 thereby providing electrical power to the DC motor 91.
  • actuation of the motor 91 causes rotation of the idler wheel 86 and, therefore, the gear 86 which in turn rotates the wheel driving gears 84. It is the rotation of the bobbins or reels 28, 36 which draw or cause the wire to be payed off from the multiple pay-offs 16, 30.
