Definitions

  • the invention relates to a device for producing a spun yarn from a fiber structure according to the preamble of claim 1.
  • Such a device is from the DE 44 31 761 C2 ( US 5,528,895 ) and with the Figures 1 and 1a shown.
  • fibers are passed through a fiber bundle passage 13 on a twisted fiber guide surface having a "back" edge 4b over a "front” edge 4c.
  • the fibers are then passed around a so-called needle 5 into a yarn passage 7 of a so-called spindle 6, wherein the rear part of the fibers is rotated by a vortex flow generated by nozzles 3 around the front part of the fibers already in the yarn passage, thereby forming a yarn becomes.
  • This having been previously spun, which will be described later in connection with the invention.
  • the so-called needle and its tip, about which the fibers are guided, is located near or in the entrance mouth 6c of the yarn passage 7 and serves as a so-called false yarn core, to prevent or reduce as far as possible that the fibers in the fiber bundle passage through the fibers inadmissible high, constricting false twist of the fibers arises, which would at least disturb the yarn formation, if not prevent it.
  • Fig. 1b is the disadvantageous state of the art ( DE 41 31 059 C2 . US 5,211,001 ) of this latter prior art, as shown in DE 44 31 761 Fig. 5 known, the fibers are not consistent, as in Fig. 1a are guided around the needle, but are guided on both sides of this needle against the inlet mouth of the yarn passage, which allegedly interferes with the binding of the fibers and allegedly can lead to a reduction in the strength of the spun yarn.
  • the Figure 1c shows an evolution of the FIG. 1 , 1a or 1a, by the fiber guide surface 4b here, as seen, is helically shaped and the fibers are also guided helically in its course from the nip X to the end E 5 of the helical surface also helically and then further helical to a fiber guide pin, similar fiber guide pin 5 of FIG. 1 , are wound around before the fibers are caught by the rotating air stream and turned into a Y yarn. It can be seen that the rear ends of the fibers f 11 are bent to the mouth portion of the spindle 6 and thereby detected by the rotating air flow and around the front ends, which are already in the center of the fiber flow, wound around thereby the yarn form.
  • the Figure 1c equals to FIG. 6 from the DE 19603291 A 1 ( US 5647197 ) wherein the characteristics of the spindle 6, the Garn trimlasses 7 and the venting cavity 8 of the FIG. 1 are taken over, while the element e 2, which has a similar function as the needle 5 of FIGS. 1 to 1b , was left that way. From this Figure 1c It can also be seen that the fibers from a helical formation are transferred to the entrance of this spindle.
  • JP 409106368 U which in contrast to FIG. 1 does not have a needle, but a blunt cone 6 with a flat fiber guide surface, which is a part of the fiber guide channel 13 and whose tip is arranged substantially concentric with the fiber guide 7 course.
  • the purpose of this cone is the same as that of the tip 5, namely to produce a so-called false twine core, to prevent the fibers from being twisted wrong, that is, false twist from the tip backwards against the nip of the exit rollers, resulting in truly turning the fibers to form the yarn would at least partially prevent it.
  • the object is solved by the characterizing features of claim 1.
  • the fiber guiding surface advantageously has a fiber discharge edge over and through which the fibers are guided in a substantially flat juxtaposition formation against an inlet mouth of a yarn guide channel.
  • the Fig. 1 shows a housing 1 with the housing parts 1 a and 1 b with a built therein nozzle block 2, which contains jet nozzles 3, by means of which an aforementioned vortex flow is generated, and a so-called needle holder 4 with the inserted therein needle. 5
  • Fig. 1 As can be seen, the turbulence produces a rightward twist in the direction of the arrow (as viewed in the figure), and accordingly the supplied fibers F are fed in this direction of rotation about the needle 5 against an end face 6a of the so-called spindle 6 and into a yarn passage 7 the spindle 6 is guided.
  • the nozzle block 2 there is a relatively large distance between the nozzle block 2 and the end face 6a of the spindle, since there must be room for the needle 5 and its tip at this distance.
  • the fibers F are conveyed in a fiber guide channel 13 on the aforementioned fiber guide surface due to a suctioned air flow against the tip 5 of the needle 5.
  • the compressed air for the jet nozzles 3 is supplied by means of a Druck Kunststoffverteilraumes 11 the jet nozzles evenly.
  • Fig. 1b which the state of the art to the aforementioned Figures 1 and 1a shows that this figure is contrary to Fig. 1a in addition, a needle holder extension 4a ', which protrudes from an end face 4' and the needle 5 includes. That is, the fibers are guided over the entire extension, which arises due to the contour of the needle holder 4, against the inlet of the spindle 6.
  • the invention according to the Fig. 2-2c a fiber delivery edge 29 which is located very close to an inlet port 35 (FIG. Fig. 2a ) of a Garn enclosureskanals 45, which is provided within a so-called spindle 32 and that advantageously with a predetermined distance A ( Fig. 2c ) between the fiber discharge edge 29 and the inlet mouth 35 and a predetermined distance B between an imaginary plane E containing the edge, parallel to a center line 47 of the yarn guide channel 45, and said center line 47.
  • the distance A corresponds to a range of 0.1 to 1.0 mm, depending on the type of fiber and average fiber length and corresponding test results.
  • the distance B depends on a diameter G of the inlet mouth 35 and, depending on the results of the test, lies within a range of 10 to 40% of the said diameter G.
  • the fiber delivery edge has a length D.1 ( Fig. 2a ), which is in a ratio of 1: 5 to the diameter G of Garn entryskanales 45 and from an end face 30 ( Fig. 2 ) of a fiber conveying element 27 and a fiber guiding surface 28 of the element 27 is formed.
  • the end face 30 lies, with a height C ( Fig. 2c ), within the range of the diameter G and has an empirically determined distance H between the plane E and the opposite inner wall 48 of the Garn entryskanales 45 on.
  • the fiber conveying element 27 is guided in a received in a nozzle block 20 support member 37 and forms with this support member 26 a fiber conveying channel forming space.
  • the fiber conveying element 27 has at the entrance to a fiber receiving edge 31, around which the fibers are guided, which are conveyed by a fiber feed roller 39. These fibers are lifted from the conveyor roller by the suction conveyor 39 by means of a suction air flow and conveyed through the fiber conveying channel 26.
  • the suction air flow is produced by a jet of air generated in jet nozzles 21 with a blowing direction 38 due to an injector effect.
  • jet nozzles are, as with the Figures 2 and 2b shown in a nozzle block 20 on the one hand with an angle ⁇ ( Fig. 2 ) to produce the aforementioned injector action and, on the other hand, at an angle ⁇ ( Fig. 2b ) are inclined to produce an air vortex, which with a direction of rotation 24 on a cone 36 of the Fiber conveying element 27 along and around the spindle front surface 34 (FIG. Fig. 2a ) turns around, as mentioned below, to form a yarn in Garn Adjustskanal 45 of the spindle 32.
  • a yarn 46 ( Fig. 2a ) are delivered by the fiber conveying roller 39 fibers F by means of said suction air stream in the fiber conveying channel 26, as mentioned, lifted off the fiber feed roller 39 and on the fiber guide surface 28 in a conveying direction 25 (Fig. Fig. 2 ) is guided against the fiber delivery edge 29. From this discharge edge, leading ends of the fibers are fed through the spindle inlet mouth 35 into the yarn guide channel 45 while the rear ends 49 of these fibers fold down as the trailing ends are exposed and caught by the rotating air flow, so as to further convey the fibers In Garn Replacementskanal 45 a yarn 46 is formed, which has a yarn character similar to the ring yarn.
  • the width D.1 ( Fig. 2a ), as shown by dotted lines, expanded on the one hand, to show that this width can be expanded, on the other hand, to illustrate that this extended width may with FIG. 2a shown vortex chamber 22 reduced, if not disturbing changed by the eddy current can not develop in it so that the fiber ends 49 can be detected with the desired energy from the eddy current. This must also be determined by means of empirical experiments.
  • the aforementioned yarn formation happens after the beginning of a piecing process of any kind, for example in which a yarn end of an already existing yarn is guided back through the yarn guide channel 45 in the region of the spindle inlet port 35 so far that fibers of this yarn end are opened by the already rotating air flow so far in that new front ends of fibers fed through the fiber guide channel 26 can be grasped by this rotating fiber structure and held therein again by withdrawing the inserted yarn end so that the subsequent back parts of the newly supplied fibers are already around the mouth part of the fiber Garn Entryskanales located front ends can wind around, so that, as a result, the aforementioned yarn can be spun with a substantially predetermined piecing again.
  • the procedure has been described with reference to an example in which the front end of a fiber as viewed in the transport direction is integrated in the fiber composite and the rear end of this fiber is free to "fold over".
  • the procedure can, however, be analogous in the case of an integrated rear end of the fiber, wherein the front end is free and due to the axial component of the vortex air flow is applied to the spindle front surface 34.
  • the fiber parts applied to the spindle front surface 34 then rotate due to the vortex air flow and are thus rotated about the integrated fiber ends.
  • FIGS. 3 and 3a show a further embodiment of the fiber guide channel 26 of the extent Figures 2-2c as here the fiber guide surface 28.1 with provided with a distance M from the fiber discharge edge 29 remote increase 40 over which the supplied fibers slide before they reach the fiber discharge edge 29.
  • the distance M corresponds to a maximum of 50% of the mean fiber length.
  • the elevation has a distance N, which is in the range of 10 to 15% of the distance M, compared with a non-increased fiber guide surface.
  • the distances M and N are to be determined empirically depending on the fiber type and fiber length.
  • slippery fibers are meant those which have weak mutual adhesion and “sticky” fibers which have mutually stronger adhesion.
  • the unmarked elements correspond to the elements of the FIGS. 2 to 2c ,
  • Another advantage of the increase is that by the movement of the fibers over this point loosening of any dirt within the fiber structure arises, which can be detected by the conveying air flow and conveyed into the open, or in a suction device.
  • FIGS. 4 and 4a show a further variant of the fiber guiding surface 28 of FIG. Figures 2-2c ,
  • the fiber guide surface at a distance P, from the fiber discharge edge 29 of a maximum of 50% of the average fiber length, a recess 41 with a radius R.1, wherein the lowest point of the recess 41 deeper lies as the edge 29 of the Figures 2-2c ,
  • the depression 41 and the radius R.1 are to be determined empirically on the basis of the fiber type and fiber length and the depression 41 serves to prevent (for example short) fibers from sideways moving away, that is to say to be lost as a departure.
  • the Figures 5-5b show a further variant of the design of the fiber delivery edge 29 by the end face 30.1 has a provided with a radius R.2 convex curve and thereby the fiber delivery edge 29 receives a width D.2.
  • the choice of radius and width is a matter of empirical attempts to optimally adapt to the type of fiber and the fiber length for the yarn design.
  • the previously mentioned fluidic optimization of the vortex chamber 22 can also be influenced with measures.
  • the unmarked elements correspond to the elements of the FIGS. 2 to 2c .
  • the Figures 6-6b have a similar idea of variation insofar as here not a convex end face 30.1 but a concave end face 30.2 is provided with a radius R.3 and an edge length of D.3.
  • the radius R.3 and the edge length D.3 must be determined empirically according to the fiber length and the fiber type. These measures serve to influence the previously mentioned constriction of the fiber at the inlet mouth.
  • the unmarked elements correspond to the elements of the FIGS. 2 to 2c .

  • the fiber guide surface here consists of a porous plate 42 made of sintered material, so that compressed air from a located below the porous plate 42 cavity 43 in a very uniform and fine distribution through the porous plate and in the fibers located thereon can flow, so that in a sense a fluidization of the fibers takes place, ie a homogeneous mixing of
