Definitions

  • the present invention relates to the field of machines for the production of stranded wire or cable, and in particular, relates to such machines which utilize a flyer bow.
  • Double twist, single twist, skip and other wire or cable manufacturing machines are commonly used to prepare various types of wire and cables (which can include coated or uncoated wires, cables, fibre optic cables and the like).
  • the resultant wires and cables are of the type that include a plurality of twisted wires which are manufactured in either one stage or in two or more stages.
  • the twisted wires are first prepared by twisting the wires together by means of so-called twinning or pairing machines.
  • Twisted wires are then made up into communications cables by means of for example, stationary take-ups, rotating take-ups (also called drum twisting machines) or other types of rotating equipment.
  • This equipment includes a bobbin cradle around which is arranged a rotatable frame or flyer bow (also simply referred to as a "bow") which is driven to turn around the cradle.
  • a rotatable frame or flyer bow also simply referred to as a "bow”
  • Wires to be twisted may be supplied from bobbins (or reels) on the bobbin cradle inside the twinning cage, twisted as they are fed to the rotating flyer bow, and then taken up on a take-up reel outside the twinning cage. As the wire travels along the flyer bow, it typically travels on the inside of the bow in a guide path, so that the "bow wire” is kept from flying off of the bow.
  • the aforementioned arrangement is referred to as an "inside-out” machine.
  • the wires to be twisted may also be supplied from outside the twisting cage and taken up on a bobbin arranged within the bobbin cradle.
  • the latter configuration is sometimes referred to as an "outside-in” machine.
  • Outside-in machines are generally preferred in individual twisting machines since the wire may be supplied from storage facilities of simple construction and greater capacity. In this case, the bobbin cradle within the twisting cage is also required to hold only a single bobbin.
  • the outside-in machine is also readily adaptable to use with a greater number of wires.
  • the wire or cable is twisted once as it enters the flyer bow, and twisted again as it exits the flyer bow.
  • the twisted elements so manufactured are directed to any type of take-up (e.g., stationary or rotating take-ups, single or double twist machines, capstan or extrusion lines) for laying up twisted wires to form a communication cable. This is typically done in one operation.
  • the wire twisting machines can be arranged horizontally or vertically, depending on the preferred plant layout. Examples of such machines, utilizing a flyer bow are described in US Patent No. 5,966,917, and in US Patent No. 5,400,579. As such, these types of machines are well known in the wire and cable production art, and will hereinafter be referred to as "flyer bow machines". Accordingly, use of this term is meant to cover any machine for wire or cable production which involves the use of a flyer bow.
  • the feed rate of the feed wire or cable can reach speeds in excess of 250 m/min.
  • the rotational speed of the flyer bow must also be increased in order to maintain a consistent lay in the wire or cable produced.
  • the rotational speed of the flyer bow must be increased by a corresponding amount, and may reach speeds of up to 3000 rpm or more.
  • the various wire or cable production machines utilizing flyer bows are production limited by, inter alia, the maximum rotational speed of the flyer bow.
  • the maximum rotational speed of the bow is limited by factors such as, the centrifugal force acting on the wire as it travels along the bow wire path, Coriolis forces, and the frictional forces from the surface of the bow. These forces all act to increase the tension on the wires beings produced. All wires, whether electrical or mechanical, have a maximum allowable tension that can be sustained for a given time period before various types of damage is created. As such, the maximum production speed of the production machinery is limited by the need to avoid or minimize unacceptable levels of this damage.
  • the present invention provides a flyer bow machine for twisting or twinning wires or cables having a rotatable bow section along which a wire or cable travels longitudinally during the twisting or twinning operation, and further comprising a carrier strip along a longitudinal surface of said bow against which the wire or cable travels, and a carrier strip drive mechanism which moves said drive strip in the direction that said wire or cable travels.
  • the present invention also provides a flyer bow having an inside surface and an outside surface, a carrier strip which travels in one direction on the inside surface of said bow, and in the opposite direction on the outside surface of said bow, pulleys located at or near the ends of said bow for moving said carrier strip from one surface of said bow to the other, and drive means for propelling at least one of said pulleys, and thus propelling said carrier strip.
  • the present invention also provides for the use of the flyer bow machine, or the flyer bow, in the production of wire or cable.
  • flyer bow machine refers to any of the known wire or cable production machines which utilize a flyer bow.
  • the present application is primarily directed to the production of wire or cable, which can include coated or uncoated strands of wire or cable, which can include, for example, optical fibre cable.
  • the wire or cable can be produced from any suitable ferrous or non-ferrous metal, including for example, copper, steel or aluminum, but might also be prepared from any other material suitable for use as a wire or cable, or component thereof, such as plastics, fibre optics and the like.
  • flyer bow machines for wire and cable production are used in a wide variety of applications, and to produce a wide variety of wire and cable products. Accordingly, while the present application is hereinafter described with particular reference to the wire industry, the skilled artisan would be aware that the present application is equally applicable in numerous other applications.
  • the primary feature of the present invention is the use of a traveling carrier strip on the flyer bow which moves longitudinally along the bow wire path.
  • the carrier strip moves at a speed which closely matches the wire speed of the wire moving along the bow wire path, and as such, the carrier strip speed is within 5% of the speed of the wire speed. More preferably, the carrier strip speed is within 1% of the speed of the wire speed, and most preferably is within 0.1 % of the speed of the wire speed.
  • the carrier strip moves preferably along the inner surface of the flyer bow in the same direction, and at the same speed, as the wire.
  • the wire is "pressed" against the carrier strip by the centrifugal force of the rotating bow.
  • the frictional force of the wire pressing against the bow is reduced and/or eliminated. With the elimination or reduction of this frictional force, the tension on the wire as it passes through the flyer bow machine is reduced.
  • the line speed and/or the rotational speed of the bow can be increased in order to prepare wires of improved quality, and/or produce wires of equal quality at increased speeds.
  • the flyer bow can be constructed of the materials known in the prior art.
  • the flyer bow is made of a fibreglass material, or of a carbon fibre material.
  • suitable materials of construction for the bow would be well known to the skilled artisan.
  • flyer bow machines are known where a wire is fed along each bow. The bows are preferably balanced so that rotational vibrations caused by the bow are minimized.
  • the endless carrier strip is preferably a loop of an appropriate material which travels in an overall circular pattern. This might include an arrangement wherein the carrier strip travels up the inside of one bow, and returns on the inside of the opposite bow. Alternatively, the carrier strip might travel up and return on one side of the bow. However, preferably, the carrier strip travels longitudinally up the inside of the bow, passes through a pulley, and returns, traveling in the opposite direction, on the outside of the bow. A second pulley would then return the carrier strip from the outside to the inside of the bow. Normally, the wires passing along the bow (the "bow wires") would contact the carrier strip on the inner surface of the bow. [0027] At least one of the pulleys is preferably linked to a carrier strip drive means in order to move the carrier strip at a selected speed.
  • the carrier strip can be flat or some other acceptable shape. For example, a concave shape will position the wire in the centre of the carrier strip, and aid in reducing any damage resulting from the Coriolis force.
  • the carrier strip is preferably an "endless" belt and can be made of any material which provides acceptable strength properties for the intended application.
  • the carrier strip can be made of fabric or plastic, but more preferably is made from a ferrous or non-ferrous material, and most preferably is made of a high tensile, metal alloy, such as steel, which would have good strength properties, while resisting stretching at the intended speeds.
  • the carrier strip is preferably held in position within a carrier strip channel on the inside surface of the bow, together with the bow wire, by a wire guide.
  • the return path of the carrier strip, on the outside surface of the bow, can be established using several strips which support and maintain the carrier strip in position on the outside of the bow.
  • the carrier strip is driven by a precision variable speed motor and control, and preferably includes a differential gear box.
  • the speed of the carrier strip can be closely controlled and matched to the speed of the bow wire.
  • the differential gear box is preferably connected to a flyer shaft by timing belts and pulleys such that the flyer bow rotation has no effect on the speed of the carrier strip.
  • the flyer shaft is preferably concentric with a carrier strip drive shaft, and is supported by ball bearings, and in turn, drives a set of spur gears and the like, to ultimately drive the carrier strip drive pulley.
  • a spring tensioning device would also be provided in order to maintain a desired amount of tension on the carrier strip.

  • the reels within shrouds 12 and 14 are rotated by electric motor 16 at a speed such that wires 'W" are fed from the reels at essentially the same speed as the production line speed.
  • bows 22 and 24 are connected by brackets 26 to a central axle 28, which in turn is connected to an electric motor (not shown) through pulley 29 used to rotate bows 22 and 24 about main body section 20.
  • a strand of wire is fed from each reel within shrouds 12 and 14 and passes around single pulleys 30, to double pulley 32.

Abstract

L'invention concerne un appareil banc à broches destiné à apparier ou à retordre un fil ou un câble dans lequel une bande support mobile est mise en oeuvre sur le banc à broches. La bande support se déplace le long du banc dans la même direction de déplacement que celle du fil ou du câble. En conséquence, la tension sur le fil ou sur le câble est réduite lorsqu'il passe dans cet appareil. Il est ainsi possible d'obtenir une productivité plus importante de fil ou de câble, ou une meilleure qualité de fil ou de câble.
