Definitions

  • the present invention relates to the field of spinning and, more particularly, relates to wire turning elements, each respectively with respect to a rolling member of the wire on itself, in particular for a machine with hollow spindles such as a guiper machine.
  • Such machines are in particular constituted by different covering modules, arranged in parallel, and each constituted by cylinders delivering the wire which passes first through a conduit, then inside a hollow spindle where it receives the filament which is wound around it, which constitutes the gimped yarn, that is to say the product leaving the gimping machine.
  • each "rotafil” therefore has an internal surface whose shape and material allow the thread to roll on itself.
  • This "rotafil” is, for example, made of elastomeric polyurethane or else of a metal covered with a granular surface of the electro-erosion type or else covered with streaks identical to those appearing on the rotor output members in open end spinning.
  • said false-twist members also called “rotofils”
  • said false-twist members have the drawback, on the one hand, of wearing out very quickly, in particular at the level of their internal surfaces, which results in very frequent replacement and, on the other hand, to ruffle the wire and to abuse the filament, which can even lead to a complete blockage of the spindle, when, as is almost always the case, they are placed downstream of the latter.
  • the general problem to be solved by the object of the present invention therefore lies in designing a device allowing the use of each "rotafil” only during the three phases of acceleration, deceleration and stopping of the machine. , that is to say applying the wire only temporarily against the internal surface of each "rotafil”, generally mounted at the spindle outlet.
  • the lifespan of each "rotafil” will be considerably extended.
  • the thread will no longer be ruffled and the filament will no longer be roughed up, which will avoid all risks of plugging the spindle.
  • the present invention relates to wire routing elements, each respectively with respect to a rolling member of the wire on itself, in particular for a hollow pin machine such as a gimp machine, elements characterized in that they are movable in translation or in rotation by means of displacement, each in the form of a connecting member connecting all the detour elements to each other, controlled by an actuating means and controlled by electrical monitoring, from a first position, during normal operation of the machine, in which each wire is no longer in contact with the corresponding detour element, and thus with the corresponding rolling member, in a second position during the acceleration, deceleration and stop phases of the machine, in which each wire is then applied by the detour element with which it is in contact, against the corresponding rolling member, so as to receive during these three phases only, the false twist necessary to assure it, at that time, regularity tension and wrapping independent of the spinning speed, and in that one of the two ends of the connecting member is connected to the actuating means, and the other is connected to the electrical monitoring stick, of which
  • the detour elements 1 of wires 2 are movable in translation or in rotation thanks to displacement means 5, each in the form of a connecting member 8 connecting all the detour elements 1 to each other, controlled by an actuating means 9 and controlled by an electrical monitoring 12, from a first position 6, during normal operation of the machine, in which each wire 2 is no longer in contact with the corresponding detour element, and thus with the corresponding rolling member 3, in a second position 7 during the acceleration, deceleration and stop phases of the machine, in which each wire 2 is then applied by the detour element 1 with which it is in contact, against the corresponding rolling member 3, so as to receive during these three phases only, the false torsion necessary to ensure it, at that time, regularity of tension and independent covering of the spinning speed, and one 10 of the two ends 10, 11 of the connecting member 8 being connected to the actuating means 9, and the other 11 being connected to the electrical monitoring 12, including one element of holding 13 ensures electrical contact 14 during the three phases of acceleration, deceleration and stopping of the machine,
  • the displacement means 5 are in the form of a connecting member 8 connecting all of the detour elements 1 to one another, controlled by an actuating means 9 and controlled by monitoring electric 12.
  • one 10 of the two ends 10 and 11 of the connecting member 8 is connected to the actuating means 9, and the other 11 is connected to the electrical monitoring 12, a holding element 13 of which provides electrical contact 14 during the three phases of acceleration, deceleration and stopping of the machine, so that the latter can only be started when the electrical contact 14 is ensured, the latter being released when the machine is running normally.
  • the holding element 13 could be, for example, a cleat.
  • the connecting member 8 may be in the form of a rod connected at its end 10 to a cylinder 9, so as to be able to move in a back and forth translation movement .
  • the detour elements 1 could be, for example, in the form of a hook 1 placed near the rolling member 3 of the wire 2 ( Figures 2 and 3), or even at least one cylinder placed near of said rolling member 3 of wire 2 ( Figure 1).
  • each wire passes through the middle of the "rotafil” 3 and is called up and wound up by the cylinders 15.
  • the rod 8 is in the position shown in Figure 2, that is to say that the hooks 1 are separated from each covered wire 2 which, passing in the middle of the "rotafil” 3, does not touch plus the inner surface 16 of said "rotafil” 3, which means that it no longer has any effect on the wrapped wire 2.
  • the wrapped wire 2 is applied against the internal surface 16 of the "rotafil" 3, precisely using the hooks 1.
  • the rod 8 is actuated by the jack 9 in the direction of the arrow 17 and is found in the position shown in FIG. 3.
  • the hooks 1 are in a position such that they make a detour to the wrapped wires 2 which, as a result, find themselves applied against the internal surface 16 of the "rotafil” 3 so as to receive the false twist which ensures them , at this time, the regularity of tension and wrapping desired.
  • the jack 9 pushes the rod 8, along arrow 18 in the position shown in Figure 2, that is to say that where the wrapped wire 2 is no longer in contact with "rotafil" 3.
  • the translation length of the detour elements 1 could be, for example, between 10 and 40 mm, preferably 20 mm.
  • the electrical monitoring 12 mounted at the end of the rod 8, by means of the cleat 13, maintains the electrical contact 14 during the three phases of acceleration, deceleration and stopping of the machine, so that the latter can only be started when the electrical contact 14 is insured. Of course, when the machine is running normally, the electrical contact 14 is released.
  • each displacement means 5 is connected directly to each detour element 1.
  • these displacement means 5 are each in the form of an actuating means 9, the latter being, for example, in the form of a jack connected to the electrical monitoring 12.
  • the displacement means 5 can also be directly in the form, for example, each of a lever which can be maneuvered individually and manually by means of a handle 19 (FIGS. 4 and 5).
  • the levers 5 can be raised or lowered all at the same time or else, and this is the object of the present variant, to be maneuvered individually by the handle 19.
