Definitions

  • the present invention relates to a Garnabzugsech a rotor spinning machine, comprising a projecting into a spinning chamber of the rotor spinning machine exhaust nozzle and a discharge channel for a yarn produced within the spinning chamber, wherein the discharge channel of the withdrawal nozzle downstream of the withdrawn from the spinning chamber yarn is downstream. Furthermore, a method for producing a yarn by means of a spinning station of a rotor spinning machine is proposed, wherein a single fiber consisting of fiber material is rotated within a spinning chamber of the spinning station with the aid of a spinning rotor to a yarn and withdrawn the yarn by means of a discharge nozzle via a discharge channel from the spinning chamber becomes.
  • rotor spinning machines are characterized in that first the individual fibers of a fed fiber sliver are separated by means of a dissolving unit and introduced into a spinning chamber. There they meet the inner wall of a spinning rotor spinning at high speed and are forced into the area of a rotor groove by the occurring centrifugal forces. The rotation of the spinning rotor finally causes a twisting of the individual fibers, which in turn wind around the end of the already produced yarn (fiber bonding process). As a result, by twisting individual fibers, a yarn or the continuous extension of an already existing yarn is continuously produced, which is finally withdrawn from the spinning chamber via a withdrawal channel of a corresponding withdrawal unit can be.
  • a corresponding rotor spinning machine is for example in the FR 2 202 961 A1 described.
  • the DE 38 24 283 C1 describes a rotor spinning machine with a trigger unit, wherein the inner wall has a helical contour and with the aid of which a false twist should be granted to the yarn. For this purpose, however, a certain yarn tension is necessary because the formation of the false twist is based on the friction between inner wall and yarn.
  • the strength of the false twist is basically limited. This is due to the fact that the bumps for the formation of the false twist must have a certain "sharp edge" in order to set the yarn in rotation. If the elevations are too sharp, there is an excessive mechanical load on the Yarn so that the positive effect of better fiber bonding is neutralized by subsequent damage to the yarn.
  • the object of the present invention is therefore to propose a take-off unit and a method for producing a yarn, in which excessive loading of the yarn is avoided despite good fiber bonding.
  • the yarn withdrawal unit of the rotor spinning machine is characterized in that the withdrawal channel for the yarn produced in the spinning chamber comprises a helically extending section, with the aid of which a false twist can be dispensed within the withdrawal channel.
  • the produced yarn obtains the desired false twist in this case by means of its helical restraint or the torsional moment which arises as a result and which acts on the yarn during the passage of said section.
  • the finished yarn receives a rotation which in turn exerts the desired torque on the yarn end in the region of the upstream groove of the spinning rotor.
  • the basic idea of the invention is therefore to guide the yarn through a helically extending discharge duct section.
  • Such a running section usually has no (sharp) edged transitions, so that excessive mechanical stress on the yarn can be excluded. Rather, the yarn is gently directed to a helical path which provides particularly gentle guidance of the yarn while still allowing the desired false twisting.
  • the yarn expediently passes through a channel which is closed on all sides and preferably has a round or lenticular cross-section, which is part of the withdrawal channel and assumes a helical course.
  • the helically extending portion is bounded by a surface portion of an insert. While the helically extending portion of the discharge channel can indeed run within a corresponding component, a surface treatment is associated with much less production effort.
  • the corresponding section can in this case be milled into the surface of the insert.
  • the insert preferably has a cylindrical outer contour, which is interrupted only by the course of the helically extending portion of the discharge channel.
  • the insert is surrounded by a wall and facing the wall surface portion of the insert has a helical and preferably groove-shaped recess which forms the helically extending portion together with the adjacent part of the wall.
  • the insert need not have an internal channel. Rather, the inventive section of the exhaust duct by interaction of a surface portion of the insert (in the form of the boundary surfaces of the recess) and hereby corresponding mating surfaces of the applied to the insert wall of the insert-bearing member of the rotor spinning machine.
  • the recesses can be introduced in a simple manner by material-removing process in an example cylindrical body, while the finished insert receiving and said wall having component with respect to the formation of the helical flue section does not need to be edited.
  • the insert and a component having the wall of the yarn withdrawal unit are separate components. Both units can be made of different materials in this case be, in particular, the use of ceramic, metal or plastic can be made.
  • the insert can be glued or screwed to the component having the wall (for example the cover of the rotor unit or of the draw-off nozzle). Also, a mutual pressing is conceivable, the use in all cases should be arranged stationary with respect to the wall having the component.
  • the wall having the component is formed by a sleeve, and that the insert is disposed within the sleeve and rotatably mounted with respect to the sleeve.
  • the sleeve thus represents another component, which serves primarily the storage of the insert and thus also the limitation of the helically extending portion of the discharge channel according to the invention.
  • the sleeve itself can in turn be mounted in a bore / opening of the lid of the spin chamber limiting housing.
  • the sleeve connects the draw-off nozzle to a draw-off pipe, the insert being placed between the draw-off nozzle and the draw-off pipe and being surrounded by the sleeve.
  • the sleeve is used in this case, the storage of the insert and the discharge nozzle and thus ensures that the discharge duct runs exactly in position from the yarn inlet of the draw-off nozzle to the exhaust pipe.
  • the sleeve is also preferably rotatable and has one or more abutment surfaces against which the exhaust nozzle and / or the exhaust pipe or with the aid of which the sleeve itself comes to rest on correspondingly adjacent components of the rotor spinning machine.
  • the sleeve is in operative connection with a drive element and can be set in a rotary motion with the aid of the drive element.
  • the helically extending portion of the discharge duct according to the invention is drivable in this case, wherein the direction of rotation can either coincide with the direction of rotation of the spinning rotor or can be oriented in opposite directions to this.
  • an improvement in the yarn structure can be achieved, wherein the rotation in particular has a positive effect on the optical uniformity of the yarn.
  • the possible rotational speed of the sleeve should preferably be in a range between 10,000 revolutions per minute (rpm) and 100,000 rpm.
  • the drive of the sleeve is preferably effected by means of a drive belt looped around the sleeve, which in turn can be in operative connection, for example via a drive axle, with a corresponding drive (eg an electric motor or a central drive shaft of the rotor spinning machine).
  • a drive belt looped around the sleeve which in turn can be in operative connection, for example via a drive axle, with a corresponding drive (eg an electric motor or a central drive shaft of the rotor spinning machine).
  • the sleeve is mounted on a rotary bearing and is displaceable relative to the stationary fixed nozzle in a rotary motion.
  • the draw-off nozzle does not undergo any rotation during yarn production, while the section of the withdrawal channel according to the invention is set in said rotation.
  • a rotary bearing can be placed between the drawing-off nozzle or a component of the yarn drawing unit and the sleeve which holds the drawing-off nozzle, which in spite of the possible relative movement between the drawing nozzle and the sleeve prevents the air from entering or leaving the drawing-off channel.
  • the sleeve is rotatably mounted in the region of its two end faces to a stable To ensure storage of the same.
  • the sleeve is non-rotatably in communication with the trigger nozzle, so that the trigger nozzle is displaceable together with the sleeve in a rotational movement. It is therefore conceivable that a relative movement between the sleeve and the spinneret is prevented, so that the produced yarn already strikes a moving surface in the region of the spinneret.
  • Sleeve and spinneret may be glued in this case, for example.
  • the insert has on its side facing the withdrawal nozzle an inlet slope opening into the guide channel and / or on its side facing away from the withdrawal nozzle an outlet slope running in extension of the guide channel.
  • the yarn is not abruptly deflected in this case at the transition of a straight-running portion of the discharge channel in the helically extending portion, but undergoes a gentle introduction into or discharge from the discharge duct section according to the invention.
  • the inlet slope and / or the outlet slope open flush into the adjacent region of the outlet channel. Stepped or sharp-edged transitions are completely avoided in this embodiment, so that a particularly gentle guidance of the yarn can be realized.
  • the said bevels are preferably formed by corresponding portions of the insert, which may be placed on the respective end faces of the same.
  • the extraction nozzle can in this case have a (centrally extending) bore and is therefore easy to manufacture. Following this bore finally follows the insert, which in turn provides at least a portion of the boundary surfaces of the helical section of the flue.
  • the insert consists of ceramic, metal or plastic.

  • the number of turns of the helical guide between 0.2 and 5, preferably between 1 and 3, is. While a high number causes a particularly strong rotation of the yarn, a small number causes only a small torsional moment acting on the yarn, so that the outer fibers of the yarn are subjected to only a small mechanical load. For example, even if the guide can have only half a turn, it still has a helical contact surface for the yarn, i. H. the contact surface has a bent portion and also extends in the longitudinal direction of the remaining discharge channel, so that a result is a helical or helical course.
  • the helically extending portion in a plan view describes a circular arc having a center angle ⁇ with respect to a longitudinal axis of the discharge channel, the amount of at least 60 °, preferably at least 120 °, more preferably at least 180 °.
  • the section according to the invention can thus, as already indicated above, have less than one complete turn, with the curved shape nevertheless a corresponding false twist generation is ensured.
  • the insert is composed of several, preferably similar, individual elements, wherein the individual elements are non-positively and / or positively connected with each other.
