Definitions

  • the present invention relates to a thread draw-off nozzle for an open-end rotor spinning device with an inlet-side nozzle funnel and an outlet-side nozzle bore which adjoins the nozzle funnel.
  • notches are arranged which run essentially radially to the nozzle bore and which have an inlet wall and an impact wall as well as a radially outer notch inlet and a radially inner notch outlet.
  • Thread take-off nozzles have become known in the prior art for open-end rotor spinning devices in multiple designs. Thread take-off nozzles of this type have the task of deflecting the spun yarn as it is being pulled out of the spinning device and of imparting a false twist to the thread being pulled off. Since the real twist in the freshly spun thread is mainly introduced between the thread take-off nozzle and the take-off device, but does not propagate sufficiently into the rotor groove, the introduction of a false twist by means of the thread take-off nozzle can significantly increase the spinning stability. To introduce the false twist, the thread take-off nozzles have surface structures which have proven themselves in principle to improve the spinning stability, but at the same time also have a considerable influence on the quality of the spun thread.
  • Spiral elevations or radially arranged notches are predominantly used as surface structures.
  • Spiral nozzles are generally considered to be advantageous for the yarn quality, but often offer less spinning stability.
  • Notched nozzles are well suited to increase spinning stability, but are considered to be more aggressive with regard to the yarn quality.
  • the DE 199 06 111 A1 which discloses the preamble of claim 1, proposes, for example, a thread draw-off nozzle with notches arranged radially in the region of the nozzle funnel, the notches being designed asymmetrically.
  • the asymmetrical notch is designed in such a way that the thread first runs gently through a very flat inlet wall to the bottom of the notch, where it is then stopped abruptly by the steep baffle. This asymmetrical configuration of the notches is intended to prevent the notches from jumping over through the circumferential thread.
  • a thread take-off nozzle is provided with radial, asymmetrical notches which are curved in a sickle shape.
  • the curvature of the notches is carried out against the curvature of the crank-like rotating yarn. This is said to be able to achieve a different effect on the yarn by means of a single notch. In this way, an increased false twist effect is to be achieved in the area of the end face, which improves the spinning stability, while in the direction of the yarn take-off channel, the effect of the impact wall, which briefly stops the thread, should predominate.
  • a trigger nozzle is known. This does not include any notches, but one or more depressions, which extend over a larger angular range of at least 10 ° or more and are designed in steps to the regular surface of the extraction nozzle. As a result, the yarn should completely lose contact with the surface of the draw-off nozzle, that is, it should skip a certain angular range. The false twist should be completely removed from the piece of yarn between the extraction nozzle and the rotor groove. This is to prevent the formation of unwanted tummy tucks in the yarn. Due to the more rapid lifting and bouncing of the thread however, an aggressive effect on the sound quality can also be expected here on the surface of the trigger nozzle.
  • the object of the present invention is to propose a thread draw-off nozzle which enables high spinning stability and yet reduces negative influences on the yarn quality.
  • a thread take-off nozzle for an open-end rotor spinning device has an inlet-side nozzle funnel and an outlet-side nozzle bore which adjoins the nozzle funnel.
  • the notches In the area of the nozzle funnel, notches extending essentially radially to the nozzle bore are arranged, the notches having an inlet wall and a baffle wall as well as a radially outer notch inlet and a radially inner notch outlet.
  • the notch base preferably has a width between 0.16 mm and 0.22 mm, in particular between 0.18 mm and 0.20 mm.
  • the thread can be gently braked as it travels over the notch floor and glides towards the baffle. The thread is thus safely exposed to the effect of the notch over a longer period of time, at the same time the thread-damaging effect of the notches is reduced. It has been shown that with such a width of the notch bottom, an optimal compromise between the effect of the notches, which increases the spinning stability, on the one hand, and the yarn quality, on the other hand, can be achieved.
  • the notches have a flatter inlet wall and a steeper baffle. This also prevents the notches from jumping through the thread, and the thread is safely guided onto the baffle that temporarily restrains it.
  • the notch outlet is arranged in an inlet area of the nozzle bore.
  • the notch thus extends into the nozzle bore and is therefore comparatively steep.
  • the thread can run better into the notches and thus experiences a particularly significant change in length in the circumferential yarn leg.
  • the change in length and thus also the thread tension peak generated by the notch is all the greater, the steeper the notch. Due to the steeper tapering of the notches into the nozzle bore, a smoother transition is achieved when reaching and leaving the notch, so that negative influences of the notches on the yarn quality can be avoided.
  • the notch outlet is arranged at a depth between 0.1 mm and 0.5 mm from an inlet of the nozzle bore.
  • the thread can be guided particularly securely into the notches and a steep notch is achieved.
  • the notch is also offset on the nozzle funnel when viewed in the pull-off direction in the direction of the nozzle bore, it is further achieved that the leg-shaped piece of yarn passes less than before over the notch inlet. This also helps to avoid thread skipping. This also reduces the yarn damaging effect of the notch run-in and improves the yarn quality.
  • the nozzle funnel has a circumferential recess in the area of the notch inlets, in particular a circumferential, preferably rounded, groove.
  • the recess can directly adjoin the notch inlets; it is also possible that an upper area of the notches with the original notch inlets is removed by the recess and thus new notch inlets which now lie deeper in the nozzle funnel result at the transition from the recess to the notch.
  • the recess itself can extend to the end face of the nozzle funnel or can only interrupt the surface of the nozzle funnel. Such a recess can further reduce an aggressive effect of the notch inlet on the thread.
  • a circumferential groove it is also possible to form the recess, for example by means of a spherical recess.
  • the inlet wall and / or the baffle wall as flat surfaces, ie. H. uncurved, are formed.
  • the notch floor between the baffle wall and the inlet wall is preferably also designed as a flat surface.
  • inlet wall and / or the baffle wall are kinked and / or curved, then a more gentle thread treatment can take place than in the case of an uncurved surface.
  • the steep surface is shortened by the kinked or curved surface and continued by a flatter surface to the top of the nozzle.
  • the angle of the baffle to a notch plane is between 32.5 ° and 47.5 °, preferably between 35 ° and 45 °, particularly preferably between 37 ° and 42 °.
  • the baffle is therefore comparatively flat. The release of the thread after his Braking through the baffle can also take place more gently and an undefined jumping of the thread can also be avoided.
  • a first angle ( ⁇ 1 ) of a first part of the inlet wall and / or the baffle to a notch plane between 32.5 ° and 47.5 °, preferably between 35 ° and 45 °, particularly preferably between 37 ° and 42 ° and a second angle ( ⁇ 2) of a second part of the inlet wall (8) and / or the baffle wall (9) to the first part between 10 ° and 20 °, preferably between 13 ° and 17 °.
  • the angle of the inlet wall to a notch center plane is between 50 ° and 65 °, preferably between 52 ° and 60 °, particularly preferably between 54 ° and 58 °.
  • the notch angle between the inlet wall and the baffle is therefore advantageously between 80 ° and 115 °, preferably between 85 ° and 110 ° and particularly preferably between 96 ° and 100 °. Such values have proven to be optimal in order to guide the thread safely into the notch and still slow down gently.
  • the depth of the notch is preferably between 0.14 mm and 0.25 mm, preferably between 0.16 mm and 0.22 mm and particularly preferably between 0.16 and 0.20 mm .
  • FIG. 1 shows a schematic sectional view of a spinning rotor 2 and a thread draw-off nozzle 1 in an open-end spinning device shown only partially in the present case.
  • the spinning rotor 2 is fed with a fiber material dissolved in individual fibers in a known manner.
  • the spinning rotor 2 rotates at high speeds during the yarn production, so that the fed fibers are deposited in the form of a fiber ring in the rotor groove 3 of the spinning rotor 2.
  • the newly spun thread F is drawn off continuously via the thread take-off nozzle 1 and extends with its end into the rotor groove 3 of the spinning rotor 2. Due to the rotation of the spinning rotor 2, a crimp-like yarn leg thus arises, in which the fibers deposited in the rotor groove 3 are integrated .
  • the thread take-off nozzle 1 has in the usual way a cylindrical nozzle bore 6 and a nozzle funnel 5, which forms a curved yarn deflecting surface for the thread F to be drawn off. Finally, on the nozzle funnel 5, on the side of the thread take-off nozzle 1 facing away from the nozzle bore 6, there is an end face 16 of the thread take-off nozzle 1, which can be designed in different ways, for example flat, curved, or also sloping in the direction of the head diameter D K of the thread take-off nozzle 1 .
  • the nozzle bore 6 is generally coaxial with the axis of rotation 15 of the spinning rotor 2, so that the thread F drawn off is deflected by approximately 90 ° over the deflection surface of the nozzle funnel 5 during its withdrawal from the rotor groove 3.
  • the twist introduced into the thread is propagate as far as possible into the rotor groove 3 in order to achieve the best possible spinning stability.
  • the surface of the nozzle funnel 5 is provided with notches 7 (see Figure 2 ) or surveys. Although these structures increase spinning stability, they can also impair yarn quality, especially in the case of notches.
  • FIG. 2 shows a schematic section through a notch 7 of a thread take-off nozzle 1, with which a particularly good and safe effect of the notch 7 on the thread F can be ensured.
  • the notch 7 has, in a manner known per se, an inlet wall 8 and an impact wall 9, which the thread F reaches in succession during its crank-shaped circulation via the nozzle funnel 5.
  • the direction of rotation of the thread F is symbolized in the present case by an arrow.
  • the inlet wall 8 and the baffle wall 9 do not directly adjoin one another, but rather a defined notch floor 12 with a defined width B between the inlet wall 8 and the baffle 9 extends.
  • the notch bottom 12 is completely flat in the present case.
  • the notch 7 thus has a simple geometric Structure, which is easy to manufacture.
  • the arrangement of the notch base 12 between the inlet wall 8 and the baffle wall 9 ensures that the thread F in each case reaches the base of the notch, which is designed here as a flat notch base 12. Undefined jumping of the thread F from the inlet wall 8 directly onto the baffle 9, as was often the case in the prior art, can thereby be avoided. It is thus ensured that the thread F reaches the notch bottom 12 and thereby experiences a sufficient change in length in the circumferential yarn leg 15.
  • the safe reaching of the notch base 12 is further supported by the fact that the thread F is slowly and gently guided in the direction of the notch base 12 via a comparatively flat inlet wall 8.
  • the angle ⁇ to a central notch plane 14 or to a parallel to it is preferably between 54 ° and 58 ° and is carried out, for example, at 56 °.
  • the notch bottom 12 also has a width B between 0.18 mm and 0.24 mm.
  • the width B of the notch bottom is 0.22 mm.
  • the angle ⁇ of the baffle 9 to the central notch plane 14, however, is preferably between 37 ° and 42 °. According to a particularly advantageous embodiment, the angle ⁇ is 40 °.
  • the thread F can be braked in a desired manner in a particularly favorable manner, but can nevertheless be gently guided out of the notch 7 again.
  • a notch angle ⁇ + ⁇ between the inlet wall 8 and the baffle 9 of, for example, 96 °.
  • the depth T of the notch 7 is between 0.16 mm and 0.20 mm.
  • the depth T is 0.18 mm.
  • the notch shape shown thus not only helps to improve the spinning stability, but also to improve the yarn quality.
  • Figure 3 shows a schematic sectional view of a thread take-off nozzle 1, in which the notches 7 (in the present case, two notches 7 are each other) visible opposite) extend into the nozzle bore 6.
  • the notch outlet 11 which in the present case is defined by the point of intersection or the line of intersection of the notch base 12 with the inner surface of the thread take-off nozzle 1 is at a distance A between 0.1 mm and 0.5 mm is located. For example, the distance A is 0.25 mm.
  • the entrance of the nozzle bore 6 is defined as the beginning of the constant inner cross section of the thread take-off nozzle 1.
  • the thread draw-off nozzle 1 has a constantly changing internal cross section in the region of the nozzle funnel 5. In the case of a tangential transition of the nozzle funnel 5 into the nozzle bore 6, the entrance of the nozzle bore 6 is thus defined by the tangential edge shown here.
  • the notches 7 are thus in a position in which the thread F is no longer pressed so strongly onto the surface of the nozzle funnel 5. Such a comparatively steep notch 7 thus has a positive effect on the yarn quality due to the fact that the circumferential yarn leg 4 brushes less strongly over the notch inlet 10 and is also advantageous for the spinning stability.
  • the notch inlet 10 is in turn defined in the case of conventional V-shaped notches by the common intersection of the inlet wall 8 and the baffle 9 with the inner surface of the nozzle funnel 5 or in the present case by the line of intersection of the notch base 12 with the inner surface of the nozzle funnel located on the input side.
  • Figure 4 shows a further embodiment of a thread draw-off nozzle 1, in which the yarn-damaging effect of the notch inlet 10 is mitigated by a circumferential recess 13, here a circumferential groove 13a.
  • the circumferential groove 13a preferably has a radius R 1 between 0.15 mm and 0.3 mm and, in the present case, is designed such that it merely interrupts the surface of the nozzle funnel 5.
  • the circumferential groove 13a could also be designed such that it extends into the end face 16 of the thread take-off nozzle 1.
  • the notch inlets 10 or comparatively sharp transition between the curved surface of the nozzle funnel 5 and the notch 7 can thereby be made gentler.
  • Figure 5 shows another embodiment of a thread draw-off nozzle 1, in which the notch inlets 10 have been defused by a spherical recess 13b.
  • the radius R 2 of the spherical recess 13b is preferably matched to the inner diameter D I of the nozzle bore 6 and is between 0.7 ⁇ D I and 0.9 ⁇ D I.
  • the radius R 2 is 0.8 ⁇ D I.
  • Figure 6 finally shows a plan view of a thread take-off nozzle 1 with the notch 7 described with a defined notch bottom 12.
  • the arrow again shows the direction of rotation of the circumferential yarn leg 4.
  • the flatter inlet wall 8 and the steeper baffle wall 9 can also be seen.
  • a total of four notches 7 are arranged evenly distributed over the circumference, but an embodiment with only three notches 7 or more than four notches 7 would also be possible.
  • a notch 7 is shown, in which the baffle 9 is kinked.
  • the first part of the baffle wall 9 facing the notch base 12 is inclined at an angle ⁇ 1 to the notch center plane 14.
  • the second part of the baffle 9 facing the edge of the thread draw-off nozzle 1 is flatter and has a second angle ⁇ 2 .
  • a gentler thread treatment is possible than with the notches shown above. since the baffle 9 does not slow down the thread as much.
  • Such a kinked design is also possible for the inlet wall 8 in addition or as an alternative to the kinked baffle 9.
