Definitions

  • the present invention relates to the field of wire management mechanisms in a processing system and more particularly to the field of wire management mechanisms upstream of a heat treatment interface.
  • the present invention aims to overcome these drawbacks by proposing a solution which makes it possible to eliminate this problem of homogeneity between the different treated threads.
  • the subject of the invention is thus a device for managing yarns in a yarn processing line comprising at least one drum downstream of a curling box and upstream of a means for thermally fixing the curl, said device comprising a fixed support, the entrance to the curling box being formed by one or more curling rollers for feeding the wires into the curling box, characterized in that the at least one drum is an axial drum for managing the a set of threads without tension, the drum being crossed by threads in the curling box and mounted on the fixed support of the device so as to operate a substantially axial rotation making it possible to generate at least one false twist to the treated threads.
  • the drum has an axis of rotation oriented along a substantially horizontal axis or along an axis producing an inclination relative to a horizontal axis. Additionally, the drum is arranged to perform a pendulum rotary movement around the drum axis.
  • the invention also relates to a method for managing yarns in a line for processing a set of yarns, comprising a step of generating at least one false twist of the yarns without tension during the passage of the yarns through a drum, prior to a step of thermal fixing of the wires.
  • the method is implemented in a wire management device described above.
  • the present invention relates to a device 1 for managing threads in a thread processing line downstream of a curling box 2 and upstream of a means for thermally fixing the curl, said device 1 comprising a fixed support 3 , the entrance to the curling box 2 being formed by one or more curling rollers 7 for feeding the wires into the curling box 2.
  • the device 1 comprises at least one axial drum 4 positioned upstream of the thermal fixing means , the drum 4 being crossed by threads in the curling box 2 and mounted on the fixed support 3 of the device 1 so as to operate a substantially axial rotation making it possible to generate at least one false twist to the treated threads.
  • the wires are tension-free.
  • the tilting by rotation of the drum 4 allows a modification of the distribution of the portion of the wires present in the drum within the strand of wires which brings them together.
  • This modification of the distribution of the threads by the drum 4 in the treatment line thus allows a reorganization of the threads within of the strand over their entire respective length.
  • the generation of this false twist allows different portions of the same yarn to be arranged differently along the processing line, for example on the conveyor belt, and in particular at each of the yarn processing stages. with the other wires of the strand.
  • the invention also relates to a method of managing yarns in a yarn processing line, comprising a step of generating at least one false twist of the yarns during the passage of the yarns through the drum, prior to a fixing step thermal wires.
  • the wire management device 1 is characterized in that the drum 4 is mounted on the fixed support 3 of the device 1 and arranged to operate a pendulum rotary movement around the axis drum 4.
  • the drum 4 is associated with a motor means for driving it in rotation.
  • This association can be carried out by any known mechanism, for example a drive belt or a gear.
  • the axis of rotation of the drum 4 is oriented along a substantially horizontal axis. According to this construction, the movement of the wires through the drum 4 is generated either upstream by the arrival of the wires by the feed rack which jams the drum 4 in a pendulum swing, or downstream by traction of the wires deposited on a training means, for example a treadmill, or again a combination of these two phenomena.
  • the pendulum rocker of the drum 4 makes it possible to limit or even eliminate the tensions on the wires when they are pulled by the drive means downstream of the drum 4.
  • the axis of rotation of the drum 4 is oriented along an axis producing an inclination relative to a horizontal axis.
  • this inclination is carried out from a high point upstream of the drum 4 towards a low point downstream of the drum 4.
  • Such an inclination makes it possible to facilitate the movement of the wires through the drum 4 from a high point to a low point while taking advantage of of the gravity of the wires which constitute the strand which passes through the drum 4.
  • the invention also relates more specifically to the drum 4 adapted to allow the generation of a false twist on the different threads which pass through it.
  • the drum 4 of the invention has a body 4a of substantially cylindrical shape with a circular or oval section.
  • this shape could be of polygonal section, for example pentagonal, hexagonal or octagonal.
  • the drum 4 of the invention is characterized in that the interior surface 4c of the body 4a of the drum 4 has a substantially conical shape.
  • the conical arrangement is preferably arranged from a restricted upstream opening towards a wide downstream opening. Such an arrangement makes it possible to carry out easier installation at the outlet of the drum 4, for example at a specific point of a drive means such as a treadmill.
  • the body 4a of the drum 4 has a substantially axial tubular shape. However, this axis of the body 4a of the drum 4 may be different from the axis of rotation of the drum 4 during its operation for the generation of false twists. However, according to a preferred construction method, the axis of rotation of the drum 4 coincides with the axis of the body 4a of the drum 4.
  • the drum 4 is characterized in that it comprises at least one gripping surface 6 produced by at least one relief of the interior surface in a section perpendicular to the axis of the drum 4.
  • This surface d The hook 6 participates in the rotational drive of the wires to allow false twists to be generated, jointly with the rotation of the drum 4. In addition to the rotational drive, this gripping surface 6 must however allow the wires to slide through the body 4a of the drum 4.
  • this gripping surface 6 is produced continuously along the length of the interior surface 4c of the drum 4 between the upstream opening 4d and the downstream opening 4e.
  • This gripping surface 6 can also be continuous or discontinuous along the periphery of the interior surface 4c of the drum 4.
  • this gripping surface 6 is produced by a rough surface, for example of the emery cloth type deposited on all or part of the interior surface 4c of the body 4a of the drum 4.
  • the drum 4 is characterized in that it comprises at least one gripping surface 6 produced by at least one relief 6a of the interior surface 4c.
  • This relief 6a which projects beyond the interior surface 4c allows the different wires to be driven in rotation with the drum 4 at the level of the portion of wires which passes through this drum 4.
  • This relief 6a can be specific to a drive in rotation of the wires in a particular direction of rotation of the drum 4.
  • the relief 6a which forms this gripping surface 6 in the drum 4 is arranged so as to produce a continuous relief 6a over the length of the interior surface 4c of the drum 4 between the upstream opening 4d and the opening swallows 4th.
  • the relief 6a is constructed so as to present a variation in its height between a greater height at a point near the upstream opening 4d and a lesser height at a nearby point. of the opening swallows 4th.
  • the relief 6a comprising an axis of symmetry S which makes an intersection with the axis of rotation of the drum 4 in a section perpendicular to the axis of the structure of the drum 4.
  • the realization of a relief 6a comprising such symmetry makes it possible to rotate the different wires by the drum 4 which is identical in both directions of rotation of the drum 4.
  • Such a construction thus facilitates the generation of homogeneous false twists at the level of the different wires moving in the drum 4.
  • the interior surface 4c of the body 4a of the drum 4 comprises at least two gripping surfaces 6 of at least one wire.
  • the multiplication of the number of gripping surfaces 6 of the wire inside the drum 4 allows optimization of the rotational drive of the wires with the rocker of the drum 4.
