Definitions

  • the present invention relates to an assembly machine by twisting conductive cables, intended in particular for transmission data and the creation of telephone connections.
  • a wire consists of a central copper conductor, surrounded by a sheath of insulating material.
  • the twist on the wire may degrade the quality, modify the geometry and physical characteristics of it, by separation between the copper element and the surrounding insulation. Now, for high information rates of up to 600 MHz, it is imperative that the cable has no electrical fault.
  • a first solution for making a traditional cable consists in forming a pair from two wires unwound on two reels, the two wires passing over a lyre performing the assembly by twisting of two sons. The pair thus obtained is wound on a reel. Four spools of pairs of wires are unwound simultaneously in order to achieve an assembly of the four pairs of wires by twisting using a lyre.
  • twinner group comprising four sets, each set comprising a lyre mounted on a frame, which assembles by twist of two wires which are unwound from two coils housed in the volume of revolution of the lyre. Twisted pairs leaving the group twinner are assembled using a single or double machine torsion. Given the drawbacks inherent in successive twists in the same direction as a wire undergoes, it is desirable to proceed, to each wire, at a first twist in the opposite direction to the pairing twist and assembly, so that the finished wire undergoes the least stress possible, and that the resulting twist on the wire is lower.
  • the object of the invention is to provide an assembly machine by twisting of conductive cables intended for data transmission, which allows in particular the production of cables during a single step in which each wire undergoes a prior reverse twist.
  • This machine has the general geometry of a machine so-called twinner group, with the additional possibility of performing, for each wire, two twists in opposite directions, one twist in a first direction then a twinning twist in a second direction so obtain a twisted pair in which the wires have the least possible residual stress.
  • Figure 1 is a side view of an installation comprising four machines according to the invention and making it possible to obtain a cable made up of four pairs of wires.
  • Figure 2 is a top view of this machine.
  • Figure 3 is a top view in partial section of the machine according to the invention.
  • Figure 4 is a perspective view schematically illustrating the path of the wires inside the machine.
  • FIG. 1 represents an installation comprising four machines grouped two by two.
  • the two groups of machines are axially aligned with each other.
  • Each machine 2 of a first group makes it possible to obtain a pair of wires 3a assembled by torsion.
  • the wires 3a pass over the group comprising the two machines 4.
  • the two machines 4 provide two pairs of wires 3b which are guided parallel to the wires 3a to be assembled with the latter by twisting at a post not shown in the drawings.
  • Each machine comprises a frame 5 on which are mounted pivoting two coaxial hollow shafts, by means of bearings 7.
  • the hollow shafts are rotated by belts 8 from a motor shaft 9.
  • the two hollow shafts 6 are connected by a curved piece 10 forming a lyre, equipped with means for guiding wires with assembly of these by twisting.
  • On the hollow shafts 6 is mounted with interposition of bearings 13 a large cradle 12 disposed inside the volume defined by the large lyre 10 during its rotation. So when the large lyre 10 rotates, the large cradle 12 does not rotate around its axis.
  • This large cradle 12 has at least one central crosspiece 14 perpendicular to the axis of the hollow shafts 6, delimiting two compartments.
  • each small lyre is mounted by means of two supports 16 coaxial, respectively on the large cradle 12 and on the cross member 14 of it with the interposition of bearings 17.
  • the rotational drive of each small lyre 15 is produced from a hollow shaft 6 by by means of a first belt 18 passing around the hollow shaft, driving a secondary shaft 19, which itself drives a belt 20 wedged on a support 16 of the small lyre.
  • a small cradle 22 Inside each little lyre 15, is arranged a small cradle 22.
  • Each small cradle is mounted on the supports 16 of the corresponding small lyre 15 with the interposition of bearings 23.
  • Each small cradle 22 is used for mounting a coil 24.
  • the small cradle carries on one side a fixed point on which is engaged the coil, and on the other side a tip 25 axially displaceable by through a pinion 26 meshing with a rack for cause either the tightening of the coil by the tip 25 or on the contrary the retraction of this same point.
  • an electric motor 27 on the output shaft of which a pinion is wedged meshing with a pinion 28 wedged on the point 25.
  • each coil 24 is offset from the axis common to hollow trees, large cradle, small lyres and, small cradles.
  • the supply of each electric motor 27 as well as the control of the movement of each coil are achieved through of collectors 30 mounted on the rotating parts and rubbing on coals integral with fixed parts opposite.
  • each wire from a spool 24 goes on a detaching roller 32 then on pulleys 33 which bring the wire axially and towards the outside on a small lyre 15.
  • the wire follows this small lyre and undergoes a twist taking into account of the rotation of this small lyre, in order to exit axially towards the interior.
  • the two wires unwound from the two coils pass over pulleys parallel 34, then on jacks 35 for regulating the thread tension, and are guided in parallel on pulleys 36 integral with the large cradle.
  • the two parallel wires exit axially from the large cradle 12 and are supported by the great lyre 10 which they follow along its entire length, before coming out axially at the other end of the machine.
  • the scrolling movement of the two wires associated with the rotating movement of the large lyre, causes these two wires to be assembled by twisting.
  • the small lyre 15 located in the right compartment in the drawing turns in the opposite direction of the large lyre, while the small lyre 15 located in the left compartment turns in the same direction as the great lyre.
  • the machine represented in the drawing aims first of all to realize the twist of each of the wires of the two coils in a first direction, then to realize the assembly by twisting in the other direction, so that the wire, after formation of the pair has the least internal stresses possible.
  • the invention provides a great improvement to the existing technique by providing a machine making it possible to obtain assembled wires in a single operation, with the possibility of twisting these wires before assembling them one to the other by twisting.
