Definitions

  • the present invention relates to a spinning station of a roving machine for producing a roving from a fiber structure, the spinning station having a vortex chamber with an inlet opening for the fiber structure and a yarn forming element extending at least partially into the vortex chamber, the spinning position having spinnerets directed into the vortex chamber which open into the swirl chamber in the area of a wall surrounding the swirl chamber and via which air can be introduced into the swirl chamber in a predetermined direction of rotation in order to give the fiber structure fed in a transport direction a rotation in the mentioned direction of rotation in the area of an inlet opening of the yarn forming element, and wherein the Yarn-forming element has a take-off channel adjoining the inlet opening, via which the yarn can be withdrawn from the swirl chamber.
  • Roving is made from fiber ribbons that have been pretreated (e.g. doubled) with the aid of stretchers and serves as a template for the subsequent spinning process, in which the individual fibers of the roving are spun into a fiber yarn, for example with the aid of a ring spinning machine.
  • it has proven useful to stretch the submitted fiber structure during the production of the roving with the aid of a drafting system, which is usually part of the roving machine, and then to provide it with a protective twist.
  • the stated strength is important in order to prevent the roving from tearing when it is wound onto a bobbin or while it is being fed to the downstream spinning machine.
  • the protective rotation granted must be so strong that a cohesion of the individual fibers is guaranteed during the individual winding and unwinding processes as well as the corresponding transport processes between the respective machine types.
  • the protective twist it must be ensured that the roving can be processed further in a spinning machine - the roving must therefore still be capable of drawing.
  • flyers In order to produce a corresponding roving, so-called flyers are primarily used, but their delivery speed is limited due to the centrifugal forces that occur is. There have therefore already been various suggestions to bypass the flyer or to replace it with an alternative type of machine (see for example EP 0 375 242 A2 , DE 32 37 989 C2 ).
  • WO 2013/003962 a document according to Article 54 (3) EPC, relates to a roving machine for producing a roving from a fiber structure, the roving machine comprising at least one spinning position which has a swirl chamber with an inlet opening for the fiber structure and a roving element which extends at least partially into the swirl chamber
  • the swirl chamber being assigned spinnerets, via which air can be guided into the swirl chamber in order to give the fiber structure a protective rotation after a piecing process in the area of the inlet opening, and wherein the spindle has a discharge duct through which the roving provided with the protective twist can be withdrawn from the swirl chamber.
  • spinning nozzles are also assigned to the vortex chamber, the spinning nozzles each having a flow direction which is oriented in the direction of the inlet opening of the spindle.
  • the object of the present invention is therefore to propose a spinning station for an air-jet spinning machine used to produce roving, with which a roving of particularly high quality can be produced.
  • the spinning station is characterized in that the wall of the vortex chamber, following the inlet opening of the same, has a transition section which widens in the mentioned transport direction, the shape of which corresponds to the outer surface of a truncated cone.
  • the spinnerets open into the swirl chamber in the region of the transition section and each have a direction of flow that is in the direction of that surrounding the swirl chamber Wall is aligned. This ensures that an air flow can be generated with the aid of the spinneret, which for the most part extends into the gap that is present between the yarn-forming element and said wall and thus hits the fibers or fiber ends of the fiber structure surrounding the yarn-forming element from the outside and the desired protective rotation is generated.
  • the invention does not provide for the entry of the spinnerets in the area of a cylindrical section or a stepped annular edge. Rather, a conical area is provided following the inlet opening, which, starting from the inlet opening, causes a cross-sectional expansion of the vortex chamber and serves as the air outlet area of the spinnerets.
  • the fact that the transition section adjoins the inlet opening is of course not to be interpreted in such a way that there must be a direct transition between the inlet opening and the transition section according to the invention (even if such a design appears to be quite advantageous). Rather, it is of course also possible for an additional intermediate section to be located between the inlet opening and the transition section.
  • the spinnerets should open into the vortex chamber in such a way that their outlet opening merges into the transition section on all sides. This ensures that the spinnerets still open completely into the swirl chamber in the area of the transition section even in the event of an undesired, production-related lateral offset.
  • the transition section merges into a cylindrical section in the direction of transport of the fiber structure.
  • the transition can be fluid or even step-shaped, that is to say immediately.
  • the cylindrical section should also have a length in the direction of transport of the fiber structure, the amount of which is greater than the diameter of the cylindrical section in this area, in order to ensure a particularly homogeneous air flow.
  • one or more further sections can adjoin the cylindrical section (seen in the direction of transport) Shape deviates from the shape of a cylinder.
  • a section is conceivable whose shape - comparable to the shape of the transition section according to the invention - corresponds to the lateral surface of a truncated cone.
  • each spinneret in a section running parallel to the respective longitudinal axis and parallel to the longitudinal axis of the draw-off channel includes an angle ⁇ with the longitudinal axis of the draw-off channel, the value of which has a value between 75 ° and 40 °. If this area is maintained, the air flow generated by the spinnerets is aligned which enables a particularly homogeneous protective twist distribution.
  • An extraordinarily high quality roving can be produced if the stated value is between 70 ° and 50 °, a value of 60 ° having proven to be particularly favorable.
  • the surface line of the transition section encloses an angle ⁇ with the longitudinal axis of the exhaust duct, the value of which has a value between 80 ° and 15 °.
  • the surface line is defined here as a line that lies on the surface of the transition section and in a common plane with the longitudinal axis of the flue.
  • the said angle assumes a value between 50 ° and 20 °, since in this case an air flow is generated (which among other things depends on the shape and orientation of the inner surface of the vortex chamber forming the transition section) the help of which the fiber structure can be given a particularly uniform protective twist.
  • an angle of 30 ° is preferred.
  • the sum of the amounts of the angles mentioned ( ⁇ and ⁇ ) results in a value between 75 ° and 105 °, preferably a value of 90 °.
  • the spinnerets each run in a section running perpendicular to the longitudinal axis of the exhaust duct between the longitudinal axis of the exhaust duct and a tangent of the wall of the vortex chamber.
  • the spinnerets do not open directly tangentially into the swirl chamber, as is customary with known spinning stations which are used to produce a finished yarn. Rather, the spinnerets should be in the section mentioned be directed into the gap which is formed between the wall of the swirl chamber and the outer surface of the yarn forming element. In this case, the spinnerets do not merge smoothly into the aforementioned wall. Rather, the transition between the inner walls of the spinnerets and the inner wall of the transition section takes place in the form of a certain bevel.
  • the longitudinal axes of the spinnerets each run parallel to a tangent of the wall of the vortex chamber in a section running perpendicular to the longitudinal axis of the exhaust duct.
  • the longitudinal axes of the spinnerets lie on a line in a section perpendicular to the draw-off channel, which are closer to the draw-off channel than the longitudinal axes of spinnerets which open directly tangentially into the swirl chamber.
  • the transition section has a diameter on its side facing the inlet opening, the amount of which has a value between 14 mm and 8 mm.
  • a diameter in this area ensures that the transition section can experience the desired increase in diameter in the direction of transport of the fiber strand with the alignment of the surface line described above and thereby assumes a diameter that results in the desired curvature of the wall of the vortex chamber.
  • a diameter is preferred, the value of which has a value between 12 mm and 9 mm, a value of 10 mm having proven particularly useful.
  • the transition section has a diameter on its side facing away from the inlet opening, the amount of which has a value between 16 mm and 10 mm.
  • the diameter of the majority of the swirl chamber (or its section in the area of the inlet opening of the yarn forming element) is also determined by the diameter mentioned.
  • the choice of the diameter thus has a direct influence on the "curvature" of the vortex air and thus the strength with which the fiber ends captured by the vortex air are bent (see also the following explanations on the outside diameter of the Yarn forming element).
  • values between 14 mm and 11 mm have proven useful, with a value of 12.5 mm being particularly suitable.
  • the yarn-forming element has a cylindrical outer contour in the area of the cylindrical section of the swirl chamber. If at the same time the wall of the vortex chamber has a cylindrical profile in the area of the cylindrical outer contour of the yarn-forming element (i.e. the wall and the outer contour of the yarn-forming element run concentrically over a certain area), an annular gap with a constant flow cross-section is created. Finally, a vortex air flow can be generated within the annular gap, with the aid of which the desired protective rotation can be generated particularly reliably and evenly.
  • the yarn-forming element at least in the area in which it has a cylindrical outer contour, has an outer diameter whose amount is between 5 mm and 14 mm, preferably between 10 mm and 11.5 mm. It has been shown that, particularly in the area of the inlet opening of the yarn forming element and the adjoining area with a cylindrical outer contour, some of the fibers that are not completely protected inside the fiber structure are captured by the air flow. These are partially pulled out of the fiber structure and finally looped around the respective inner "core fibers" so that the desired protective twist is created as a result.
  • the extent to which the fibers are bent over depends in particular on the outer diameter of the yarn forming element in the area of said cylindrical section, which preferably extends into the area of the end face of the yarn forming element having the inlet opening. A smaller outside diameter causes more bending, while a larger outside diameter only results in a relatively small bending of the fiber ends. If the outside diameter of the yarn-forming element is selected as indicated above, the yarn-forming element has an outer jacket surface in the region of its cylindrical section, which enables an optimal angular velocity of the air vortices generated by the air flowing into the vortex chamber. A smaller diameter would ultimately lead to an increased angular velocity, while an outside diameter greater than 14 mm would result in too little bending of the fibers and thus only inadequate protective rotation.
  • the inlet opening for the roving to be withdrawn from the swirl chamber has a diameter whose amount is between 4 mm and 12 mm, preferably between 6 mm and 8 mm. If the specified diameter limits are adhered to, a particularly advantageous air flow arises in the area of the inlet opening of the yarn forming element, which has the effect that only part of the outer fiber ends are captured and wrapped around the actual fiber core with the desired strength. If, on the other hand, the diameter is below 4 mm, one gradually gets into the range that is known from conventional air-jet spinning and which results in a relatively strong yarn that is only conditionally suitable as a roving.
  • the air pressure of the air supplied via the air nozzles must be increased significantly in order to ensure the necessary vortex flow within the vortex chamber, since part of the inflowing air leaves the vortex chamber via the inlet opening of the yarn forming element without Contribute to vortex formation.
  • a roving with a yarn-forming element the inlet opening of which has a diameter outside the range according to the invention.
  • Figure 1 shows a schematic view of a section of a roving machine.
  • the roving machine can comprise a drafting system 22 which is supplied with a fiber structure 3, for example in the form of a doubled drafting sliver.
  • the shown roving machine basically comprises a spinning station 1 spaced apart from the drafting system 22 with an internal vortex chamber 4 in which the fiber structure 3 or at least some of the fibers of the fiber structure 3 are provided with a protective twist (the exact mode of operation of the spinning station 1 is explained below described in more detail).
  • the roving machine can also comprise a pair of take-off rollers 21 and a winding device 20 (also shown schematically) for the roving 2, which is connected downstream of the pair of take-off rollers 21.
  • the device according to the invention does not necessarily have to have a drafting system 22, as shown in FIG Figure 1 is shown.
  • the pair of take-off rollers 21 is also not absolutely necessary.
  • the roving machine now works according to a special air-jet spinning process.
  • the fiber structure 3 is guided in a transport direction T via an inlet opening 5 of a fiber guide element 19 (preferably designed as a separate component) into the swirl chamber 4 of the spinning station 1.
  • a fiber guide element 19 preferably designed as a separate component
  • Some of the fibers are here pulled out at least a little bit from the fiber structure 3 and wound around the tip of a yarn-forming element 6 protruding into the swirl chamber 4.
  • the individual spinnerets 7 are preferably arranged in a rotationally symmetrical manner to one another (see FIG Figure 3 , which is a sectional view along the section AA 'in Figure 2 shows, the spinnerets 7, which for the most part run above the cut surface and therefore cannot actually be seen, are represented by dashed lines).
  • the spinnerets 7 each have a flow direction which is oriented in the direction of a wall 8 surrounding the swirl chamber 4, so that the air flow generated is at least for the most part in a spiral shape between the outer surface 12 of the yarn forming element 6 and the wall 8 of the vortex chamber 4 extends.
  • the fibers of the fiber structure 3 are drawn off from the swirl chamber 4 via an inlet opening 9 of the yarn-forming element 6 and a take-off channel 10 arranged within the yarn-forming element 6 and adjoining the inlet opening 9.
  • the free fiber ends are also drawn on a spiral path in the direction of the inlet opening 9 and are looped around the central core fibers as winding fibers - resulting in a roving 2 with the desired protective twist.
  • the roving 2 Due to the only partial twisting of the fibers, the roving 2 has a (residual) draftability which is essential for the further processing of the roving 2 in a subsequent spinning machine, for example a ring spinning machine.
  • Conventional air-jet spinning devices give the fiber structure 3 such a strong twist that the necessary delay after the yarn production is no longer necessary is possible. In this case, this is also desirable, since conventional air-jet spinning machines are designed to produce a finished yarn which, as a rule, should be characterized by high strength.
  • the spinning station 1 preferably has a twist damper element inserted into the fiber guide element 19, for example.
  • This can be designed as a fiber dispensing edge, as a pin or in another embodiment known from the prior art and prevents a rotation in the fiber structure 3 from propagating against the delivery direction of the fiber structure 3 and thus in the direction of the inlet opening 5 of the fiber guide element 19.
  • FIG. 13 shows a sectional view of the area F in FIG Figure 2 along the cut surface CC 'in Figure 3
  • the spinning nozzles 7 open into the swirl chamber 4 in the area of an annular edge 23.
  • Such a geometry is not optimal for the air flow generated with the aid of the spinning nozzles 7.
  • the respective outlet openings of the individual spinnerets 7 merge into the annular edge 23 on both sides, so that a certain step-shaped transition is created here.
  • the wall 8 of the vortex chamber 4 have a transition section 11 following the inlet opening 5, the shape of which corresponds to the outer surface of a truncated cone.
  • a transition section 11 following the inlet opening 5, the shape of which corresponds to the outer surface of a truncated cone.
  • transition section 11 is designed as a conical ring section.
  • the dimensions of the The transition section 11 should be dimensioned such that the air outlet openings of the spinnerets 7 adjacent to the vortex chamber 4 merge into the transition section 11 on all sides. An offset of the drill, with which the spinnerets 7 are usually produced, does not have a significant effect in this case on the flow pattern of the air flow generated.
  • the transition section 11 merges in the transport direction T into a cylindrical section 13 of the wall 8 of the vortex chamber 4.
  • the outer surface 12 of the yarn-forming element 6 also has at least partially a cylindrical outer contour 18 (see for example FIG Figure 6 ), then the vortex chamber 4, following the transition section 11, has an area with a constant flow cross-section, which also has a favorable effect on the vortex air flow generated.
  • FIG Figure 8 shows Figure 8 that the spinnerets 7 do not necessarily have to open tangentially into the swirl chamber 4 (as shown in FIG Figure 3 shown). Rather, it can be advantageous if the spinnerets 7 extend at a distance from a corresponding tangent 17, a spinneret 7 and a tangent 17 in each case in the FIG Figure 8 can run parallel to one another (otherwise the spinnerets 7 in FIG Figure 8 indicated by dash-dots for explanatory purposes, although they would not actually be visible in the corresponding section; compare the comments on the Figures 2 and 3 ).
  • an air flow which is advantageous for the draftability of the roving 2 results when the angle ⁇ (see Figure 9 ) has a value between the surface line 16 of the transition section 11 and the longitudinal axis 15 of the flue 10, the amount of which has a value between 80 ° and 15 °, the value advantageously being between 40 ° and 20 °.
  • an angle ⁇ of 30 ° enables an air flow with which a roving 2 can be produced which, despite the desired draftability, has a strength that enables the roving 2 to be transported further to a subsequent spinning machine.
  • each spinneret 7 in a section running parallel to the respective longitudinal axis 14 and parallel to the longitudinal axis 15 of the take-off duct 10 forms an angle ⁇ with the longitudinal axis 15 of the draw-off duct 10 (see Figure 10 ), the amount of which has a value between 75 ° and 40 °.
  • a value between 70 ° and 50 ° has proven particularly useful, with a value of 60 ° in particular promising an excellent result in terms of strength and draftability of the roving yarn 2.
