Definitions

  • the invention relates to a nozzle spinning device with a pneumatic twist nozzle arranged next to a pair of delivery rollers for taking over a non-spun yarn delivered by the pair of delivery rollers, and with an outgoing roller arranged downstream of the twist nozzle. zencru to take over the spun yarn delivered by the twist nozzle.
  • the yarn occasionally breaks in the nozzle spinning process, which is determined by an automatic monitoring system that is not part of the invention, and as a result the sliver feed is interrupted by the same automatic system.
  • the disadvantage of the known or similar device known from the above-mentioned design specification is that an automatic mechanism for eliminating such a thread break is very poor, respectively. is very cumbersome and therefore expensive to implement. This is because the yarn delivered by the swirl nozzle at high speed has to be removed with a movable suction element at the outlet mouth of the swirl nozzle and has to be guided between outfeed rolls which can be automatically separated and reclosed and which are arranged at a distance from the spinning process in order to then be transferred to a winding device to become. This disadvantage also affects, albeit less, the same, but manual, process.
  • the object of the invention is therefore to remedy this disadvantage.
  • the object is achieved in that the swirl nozzle is connected to a pneumatic guide tube which projects so close to the pair of outlet rollers that the yarn is conveyed into the converging space of the pair of outlet rollers and is thereby automatically detected by the pair of outlet rollers.
  • a nozzle spinning device 1 comprises a pneumatic swirl nozzle 3, which is connected to a pair of delivery rollers 2 and has a pneumatic guide tube 4 connected directly to it, which counteracts a discharge roller couple of 5 flows.
  • a pneumatic guide tube is to be understood as a tube which allows an air flow under normal aerodynamic conditions, i.e. without abrupt changes in cross-section and with one for pneumatic conveying pipes for fiber-typical roughness.
  • the nozzle spinning device 1 is connected downstream of a drafting device 6 which does not belong to the subject matter of the invention, to which the pair of delivery rollers 2 also belongs.
  • the drafting system 6 also comprises a middle pair of rollers 7 with guide straps 7.1 and 7.2, an input pair of rollers 8, as well as a second sliver condenser 9 arranged between the pair of rollers 7 and the pair of rollers 8 and a first sliver condenser 10 arranged in front of the pair of input rollers 8.
  • the drafting unit 6 takes over a sliver 11, which runs into the drafting device in the direction of the arrow, and is drawn into a still unspun yarn, delivered by the pair of delivery rolls 2 and automatically taken over by the pneumatic swirl nozzle 3.
  • Sliver 11 can be understood to mean a stretch belt or one or more combined flyer slits.
  • this unspun yarn is spun into a finished yarn 12 taken over from the pair of outlet rollers 5.
  • the yarn 12 leaves the pair of rollers 5 in the direction of the arrow and is finally taken over by a winding device (not shown).
  • drafting arrangement 6 instead of the drafting arrangement 6 shown, another drafting arrangement can also be used which is able to take off an unspun yarn at the same speed to deliver.
  • the swirl nozzle 3 is known per se from the German publication No. 2722319 mentioned.
  • this swirl nozzle 3 is provided with a cylindrical surface 14 and a stop 15.
  • the guide tube 4 can be fixed to the swirl nozzle 3 with a clamping ring (not shown) that encompasses the two parts.
  • a thread (not shown) can be provided for fixing the guide tube 4 to the swirl nozzle 3. In itself, this fixing is not essential to the invention.
  • the guide tube 4 has an inner wall 16, which has the same diameter as the outlet channel C when it is connected to the outlet channel C of the swirl nozzle 3.
  • the swirl nozzle 3 and the guide tube 4 can also be produced in one piece (not shown) or the tube 4 can be composed of several parts (not shown).
  • the outlet mouth 18 of the guide tube 4 projects so close to the pair of outlet rollers 5 that the yarn 12 is conveyed into the converging space 19 of the pair of outlet rollers 5 and is thereby grasped by the latter.
  • the sum of all the distances between the mouth edge 20, the mouth 18 and the cylindrical surface of the pair of outlet rollers 5, from which an air outlet cross section results between this edge 20 and the surface mentioned, may not be substantially smaller than the muzzle cross-section measured laterally to the direction of flow. This condition applies to all variants to be described.
  • the mouth 18 as a variant 18.1, respectively. 18.3, resp. 18.4 resp. 18.5 partially projecting into the converging space 19 ', adapted to the cylindrical surface of the pair of output rollers 5.
  • 5 to 9 also show how the mouth 18 as a variant 18.2, respectively. 18.3, resp. 18.4, respectively 18.5, resp. 18.6 is arranged an output roller pair 5 inclined to the direction of flow.
  • the edge 20 in FIG. 4 becomes the edge 20.1, in FIG. 5 the edge 20.2, in FIG. 6 the edge 20.3, in FIG. 7 the edge 20.4, in FIG. 8 the edge 20.5 and in FIG. 9 to edge 20.6.
  • the arrangement of the guide tube 4 must be such that its axis of symmetry (not shown) coincides with the thread path in the region of the outlet mouth.
  • the mouth edge 20 to 20.6 is the surface which lies opposite the two cylindrical surfaces of the pair of output rollers 5 and is formed by the circumference of the outlet mouth.
  • the air outlet cross section is to be understood for all variants as the area which is from the sum of all the shortest distances between the mouth edge and the opposite cylindrical surfaces of the pair of rollers 5.
  • the outlet mouth 18 and. 18.2 is arranged such that the mouth edge 20, respectively. 20.2 lies in a plane which is essentially parallel to an imaginary plane containing the axes of the output rollers.
  • the Pig. 7 to 9 also each show an outlet opening with a flow deflection directed against the pair of rollers 5.
  • the mouth 18.4 has a curved piece 21
  • the mouth 18.5 has a deflection part 22
  • the mouth 18.6 has a deflection part 23.
  • the bow piece 21 and the deflecting parts 22 and 23 support the deflection of the flow and the yarn when it is drawn into the converging space 19.
  • the curved piece 21 is formed by bending the guide tube 4 in the mouth region shown in FIG. 7.
  • the deflecting parts 22 and 23 are flat plate parts which, as in Fig. 8 and. 9 shown, with an angle of inclination ⁇ resp. ß on a milled surface in the mouth area of the outlet 18.5 or. 18.6, are attached.
  • the measure of the inclination angle resp. ß depends on the inclination of the pair of output rollers 5 to the guide tube 4, and on the speed of the air flow and is empirically determined in practice.
  • Fig. 9 shows a further measure influencing the flow direction, in which the distance between the edge 20.6 in the lowest region, i.e. compared to the lower roller 5.1, is the smallest, and is gradually increased towards the uppermost region of the edge 20.6.
  • the air outlet in the lowermost region of the edge 20.6 can be designed in such a way that the yarn 12 is certainly not conveyed outside past the lower outlet roller 5.1, past the edge 20.6, but into the converging space 19.
  • the amount of air flowing through the guide tube 4 corresponds to the amount of air emitted by the swirl nozzle 3.
  • the guide tube 4 can have a cone (not shown) that widens towards the pair of outlet rollers 5.
  • This cone can have the same opening angle (not shown) over the entire length of the guide tube.
  • the opening angle should not be significantly larger than the opening angle of the output channel C.
  • the aforementioned cross-section of the mouth is to be understood as the inner cross-section of the guide tube 4 which still exists as a complete cross-section in the region of the mouth of the guide tube.
  • this is e.g. the cross-section of the mouth 18 itself, while in the remaining figures it is the cross-section which is still completely surrounded by the pipe wall and which is immediately followed by the obliquely cut mouth 18.2 (FIG. 5) or the profiled mouth 18.1, respectively. 18.3, resp. 18.4, respectively 18.5, resp. 18.6 (Fig. 4 and 6 to 9) follows.
  • FIG. 2 shows that the nozzle spinning device can also be used in an upward spinning direction.
  • the elements are therefore identified by the same reference numerals as in FIG. 1.
  • a use, not shown, of the nozzle spinning device in a horizontal position is also possible.
