- Garnabzuqsech a rotor spinning machine and method for producing a yarn using a rotor spinning machine
- 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a yarn produced within the spinning chamber, wherein the discharge channel of the withdrawal nozzle downstream of the withdrawn from the spinning chamber yarn is downstream.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 fiber material is rotated within a spinning chamber of the spinning station by means of a spinning rotor to a yarn and the yarn withdrawn by means of a discharge nozzle via a discharge channel from the spinning chamber becomes. Finally, a take-off nozzle for a rotor spinning machine with a discharge channel is described, over which a yarn produced by means of the rotor spinning machine can be pulled off.
- 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fibers, a yarn or the continuous extension of an already existing yarn is continuously produced, which can finally be withdrawn from the spinning chamber via a withdrawal channel of a corresponding withdrawal unit.
- the strength of the false twist is basically limited. This is due to the fact that the false twist forming bumps must have some "sharp edge" to make the yarn rotate, and if the bumps are too sharp, there will be excessive mechanical stress on the yarn, causing the yarn to twist Effect of better fiber bonding is neutralized by subsequent damage to the yarn again.
- the object of the present invention is therefore to propose a draw-off unit or a draw-off nozzle and a method for producing a yarn, in which excessive loading of the yarn is avoided despite good fiber bonding.
- the object is solved by a device by a Garnabzugshim with the features of claim 1.
- 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 which Sen help the yarn within the flue a false twist can be dispensed.
- the produced yarn obtains the desired false twist in this case by means of its spiral-shaped positive guidance 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 helical 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 section is delimited by a surface section of an insert. While the helically extending portion of the flue can also 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 helical portion extending the discharge channel.
- the insert is surrounded by a wall and a wall surface facing the surface portion of the insert a helical and preferably groove-shaped depression has, which forms the helical extending portion together with the adjacent part of the wall.
- the insert need not have an internal channel.
- 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 depressions 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 discharge duct section does not have to be edited.
- the insert and a component having the wall of the yarn withdrawal unit are separate components. Both units can be made in this case of different materials, 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 a further component, which serves primarily the storage of the insert and thus also the limitation of the helical 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 insert is glued to the sleeve, with purely positive connections are conceivable (screwing, pressing, etc.).

- 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 channel 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 preferably takes place with the aid of a drive belt looped around the sleeve, which in turn, for example via a drive axle, with a corresponding drive (eg an electric motor or a central drive shaft of the rotor spinning machine) Active compound can stand.
- a drive belt looped around the sleeve which in turn, for example via a drive axle, with a corresponding drive (eg an electric motor or a central drive shaft of the rotor spinning machine) Active compound can stand.
- 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 in order to ensure stable storage thereof.
- 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 insert can thus be an integral part of the draw-off nozzle, which in this case can be exchanged together with the insert.
- a draw-off nozzle which already has the section according to the invention of the draw-off channel, so that this draw-off nozzle can also be used in already existing rotor spinning machines without the need for further constructional interventions.
- a rectilinear section of the discharge channel is arranged between a yarn inlet of the draw-off nozzle and the helically extending section.
- 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 portion of the flue.
- the insert consists of ceramic, metal or plastic.
- the insert can also be cast or produced by (surface) machining of a basic body. Also conceivable are various coatings of the insert or in particular its with the yarn coming into contact surface areas in order to adjust the friction conditions between the insert and yarn accordingly.
- the number of turns of the helical guide is between 0.2 and 5, preferably between 1 and 3. 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 1 20 °, particularly preferably at least 180 °.

- a "base coil” is used which is designed in such a way that it can be positively and / or non-positively connected to one or more further base coils number of turns of the discharge duct by the number of interconnected individual elements to vary.
- the individual elements may have, for example, one or more recesses on one of their front sides and one or more extensions on the opposite end side. If two individual elements are joined together, the extension (s) of the one individual element engage in the depression (s) of the adjacent individual element.
- the extension (s) or depression (s) preferably have a cross-section deviating from a circular shape in at least one region, so that the assembled individual elements can not be rotated relative to one another.
- a continuous exhaust duct can be formed, which extends along the entire single element.
- the insert of an initial piece, an end piece and one or more identical middle pieces is composed, wherein the starting piece has an inlet slope and the end piece has a discharge slope.
- the total length of the insert is determined (which can be dispensed with the center piece).
- the insert can also be composed of several identical individual elements, each having an inlet slope and an outlet slope.

- Figure 7 is a partially sectioned side view of another withdrawal unit according to the invention.
- FIG. 1 shows a partially sectioned side view of a known rotor spinning machine, which as a rule comprises a multiplicity of spinning stations 1 arranged side by side in the longitudinal direction of the machine (that is, perpendicular to the plane of the drawing).
- Each spinning station 1 is supplied in a known manner by means of delivery device 1 1 a fiber material 2 from a sliver can 3, which dissolved by means of an opening roller 10 in individual fibers and indicated by a in Figure 2 by dashed lines indicated (with respect to the sheet plane behind) Faserzu GmbHkanal 1 6 a spinning rotor 4 is supplied.
- the yarn 5 produced in the spinning rotor 4 is finally replaced by a, z. B.
- a pair of delivery rollers 6 comprehensive deduction device 7 deducted via an output 1 3 from the spinning unit 1, possibly checked by a yarn monitoring unit 12 for yarn defects and wound by means of a coil 9 comprehensive winding device 8.
- the spinning station 1 has a spinning chamber 22, into which the spinning body 20 is driven via a rotor shaft 20 Spinning rotor 4 protrudes and which is bounded by a housing 18 and a wegschwenkbaren cover 17. Between cover 1 7 and housing 1 8 is usually a seal 19 in order to maintain the pressure prevailing in the spinning chamber 22 negative pressure.
- the withdrawal of the produced yarn 5 finally takes place via a so-called draw-off nozzle 21 (or the yarn inlet 15), which can be anchored, for example in the form of an insert releasably in the lid 17, and which is usually in connection with a vent pipe 14, for example, with the help a carrier 34 is also mounted on the lid 17.
- the inner channels of the discharge nozzle 21, the carrier 34 and the discharge pipe 14 finally form a discharge channel 23, which ensures the necessary guidance of the yarn 5 during withdrawal from the spinning chamber 22.
- the fibers separated by the opening roller 10 are now sucked into the spinning rotor 4 during rotor spinning and forced into its inner groove 35 by the high rotational speed of the spinning rotor 4. There, they come into contact with the yarn 5 indicated in FIG. 2 and, as a result of the rotor rotation, are wound around its likewise rotating end (so-called fiber bonding process). In this way, continuous yarn 5 is produced, which can be drawn off via the draw-off nozzle 21.
- the withdrawal channel 23 comprises a helically extending section 24 for the yarn 5, with the aid of which the yarn 5 within the withdrawal channel 23 a false twist can be dispensed.
- FIG. 3 A drawing-off nozzle 21 according to the invention is shown in FIG. 3, wherein the helically extending section 24 according to the invention is formed by an insert 25 which is placed inside the draw-off channel 23 of a (generally rotating) draw-off nozzle 21, as basically also in the rotor spinning machine according to FIG Use can come.
- The, preferably groove-shaped, recess 28 is limited to the outside by the part 29 of the wall 27 adjacent to the recess 28.
- draw-off nozzle 21 does not have to be a separate item from the cover 17. Rather, in the context of the present invention, the term "take-off nozzle" is generally understood to mean that section of the spinning device which extends into the spinning rotor 4 and which comprises the front section of the discharge channel 23 adjoining the yarn inlet 15.
- FIG. 4 shows a yarn withdrawal unit according to the invention, in which the helically extending section 24 of the withdrawal channel 23 delimited by the insert 25 is not arranged inside the withdrawal nozzle 21, but in connection therewith.
- the insert 25 is mounted in this case within a sleeve 30, which in turn connects the discharge nozzle 21 with a discharge pipe 14.
- the insert 25 in order to further minimize mechanical stress on the withdrawn yarn 5 during its rotation within the helical section 24, it may be advantageous for the insert 25, as shown in FIGS. 3 and 4, to have an inlet slope 31 and / or an opening Outlet slope 32 has. As a result, sharp edges are deflected avoided, the yarn 5 is particularly gentle in the insert 25 into and / or led out of this. While the inlet bevel 31 could also be located immediately after the yarn inlet 15 (see in particular FIG. 3), it has also proved to be very advantageous if the extraction channel 23 has a straight section 33 between the yarn inlet 15 and the helically extending section 24 , In particular, conventional extraction nozzles 21 can be used in this case, which can be supplemented according to FIG. 4 with an insert 25 according to the invention.
- the insert 25 shown consists of an inlet bevel 31 having the starting piece 37, an outlet 32 having end piece 38 and a middle piece arranged therebetween 36. Start piece 37, middle piece 36 and end piece 38 in the installed state corresponding to each other Contact surfaces 39 and positively locking interlocking anti-rotation.
- the rotation-preventing means can be realized, for example, by a cooperation of corresponding extensions 40 and corresponding depressions 41.
- the middle piece 36 has an extension 40 in the region of one of its two end faces and a corresponding recess 41 in the region of the opposite end face. If the starting piece 37 in the example shown in FIG. 5 also has a corresponding recess 41 on its right-hand end, then the middle piece 36 can be fitted together in a form-fitting manner with its beginning piece 37 via its extension 40. A corresponding connection is also possible with the end piece 38, if this at his the contact piece 39 facing the middle piece 36 has an extension 40 corresponding to the recess 41 of the middle piece 36.
- the advantage of a multi-part insert 25 lies in the fact that the number of centerpieces 36 used can be varied as a function of the respective process parameters (fiber material 2 to be spun, spinning speed, etc.). If the end piece 38 is coupled directly to the starting piece 37, so you get a particularly short discharge channel 23, while this can be extended by appropriate interposition of one or more centers 36.
- each of the basic elements has an inlet bevel 31 and an outlet bevel 32 (comparable to the insert 25 in FIG. 4), wherein the inlet slope 31 and outlet slope 32 of two base elements adjacent to one another in the assembled state lie against each other in such a way Twisting is excluded and a continuous withdrawal channel 23 is formed.
- FIG. 7 shows an advantageous embodiment of the invention, in which the component having the helical section 24 can be actively driven.
- Said component may, for example, be in the form of a sleeve 30, in the interior of which an insert 25 having the section 24 according to the invention, corresponding to one of the FIGS. 4 to 6, extends.
- this in turn can, preferably via a drive belt 44 shown partially cut in FIG. 7, be connected to a drive axle 45, which in turn can be put into rotary motion by a drive (for example an electric motor, not shown).
