Definitions

  • the invention relates to an air spinning machine according to the preamble of claim 1.
  • the DE 101 33 604 A1 describes a device for reciprocating Lunten culinaryn in which the Luntenrise be controlled so that the residence time of the Luntenraising is made uniform over the width of the rolls.
  • a disadvantage of the aforementioned prior art is that despite the traversing the service life of the drafting top rollers are relatively short, especially in air spinning machines, usual service lives are in the range of a few days, so that frequent regrinding or frequent replacement of the drafting top rollers is required. Furthermore, it requires in the apparatus for traversing a complex storage of Lucasspinnaggregates to ensure the exact alignment of the Lucasspinnaggregates with respect to the pair of output rollers. In addition, there is the problem in an interruption of the spinning process and an adjoining remedy by a movable along the textile machine service car that the traversing can not be stopped during the piecing process, if it is a machine-length drive for the traversing. To circumvent this problem, it requires the use of individual drives for traversing at each job, which is associated with a great deal of technical effort.
  • Object of the present invention is to develop an air spinning machine such that longer service life of the drafting roller top rollers are possible, the disadvantages of the prior art to be overcome in a simple and cost-effective manner.
  • the output top rollers so in relation to the air spinning units are arranged so that the flow of material between the roll center and one of the roll edges.
  • the running-in of the roll coverings is displaced to an off-center region of the upper rolls or the aprons.
  • the unilateral shrinkage makes it possible, by loosening and turning the top rollers, to expose them to the fiber material flow with the undamaged surface. In this way, the service life of the top rollers is doubled before the top rollers must be reground.
  • At least the output top rollers are arranged in relation to the air-spinning unit, that the material flow deviates in each case in the same direction from the roller center.
  • the top rollers may be arranged in pairs on a respective common axis, which is easily releasably attached to the pendulum carrier.
  • the removable from the pendulum carrier top rollers are used after a simple pivoting movement by 180 ° back into the pendulum carrier, so that their non-run-in surface sections are exposed to the fiber flow.
  • the arrangement of the two air-spinning units in the fiber material flow is such that the distance to the central longitudinal axis of the pendulum carrier or to the upper roller center is unequal.
  • a further embodiment provides that the upper rollers are individually solvable from the common axis. That way you can place the top rollers on the opposite side of the common axis, exposing the non-ground portion of the top roller to the fiber material flow.
  • the upper rollers released from the axle can also be reattached on the same side of the axle after being rotated through 180 °. In this way too, it is possible to ensure that the area of the upper roller not exposed to the flow of material is exposed to the material flow.
  • the side covers which protect the top rollers against penetrating fiber material or dust, be easily releasably secured to the top rollers.
  • the top rollers are designed accordingly, so that after turning the top roller, the cover on the opposite side is repositioned.
  • the top rollers can be easily detachably mounted on the pendulum carrier by means of separate axes. This development makes it possible to remove the top rollers together with the axis of the pendulum carrier and arranged to pivot 180 ° on the opposite side.
  • the drafting device can be provided at the workstation with front and / or intermediate sliver compressors, which are arranged in the direction of material flow in alignment with the air-jet spinning unit. These support the eccentric guidance of the flow of material between the top rollers to the air spinning unit. In this way it is achieved that the fiber material flow is kept in alignment with the air-spinning unit in a line in order not to influence the spinning quality.
  • the compressors limit too large a spread of the supplied fiber material in the drafting system.
  • the sliver compressors may be arranged on a traversing device, which is a traversing allows the thread material between the roller center and a roll edge of the top rollers.
  • the traversing width is limited to a narrow area between the upper roll center and the upper roll edge, which is predetermined by the eccentric arrangement.
  • the effort is limited to the traversing of the interposed sliver compressor.
  • the influence of the traversing movement on the aligned guide of the fiber material when feeding the air-spinning unit is kept low, so that the air-spinning units can be fixedly mounted.
  • the traversing device does not require any elaborate storage of the sliver compressors, since the influence of deviations in the position of the compressors in the supply of the fiber material into the air-spinning unit is negligible.
  • FIG. 1 an air spinning machine 1 is shown, by means of which the invention will be explained.
  • Such textile machines usually have a plurality of workstations 2 arranged in a row next to one another and a so-called end frame 13 at at least one end.
  • each of the working or spinning stations 2 of such an air-spinning machine 1 has a sliver source, for example a sliver can 3, a drafting device 4, an air-spinning device 5, a yarn withdrawal device 6, a yarn cleaner 7 and a thread-changing device 8.
  • the Fadenchangier listening 8 ensures that the manufactured in the air spinning device 5 thread is wound in intersecting layers on a package 9.
  • the cheese 9 is usually held in a coil frame and is rotated by a coil drive.
  • the spinning units 2 of the air-spinning machine 1 are supplied by an automatically operating operating rotor 10, which, guided on rails 11, 12, is movable along the spinning stations 2.
  • the drafting units 4 generally comprise an input roller pair 20, a middle roller pair 21 and a pair of output rollers 23, the roller pairs each consisting of drivable lower rollers 20A, 21A, 23A and upper rollers 20B, 21B, 23B held in a pendulum carrier 17.
  • the pendulum support 17 is limited movably mounted on a support rod 30 and can by means of a lever 29 in three possible positions a) "loaded", b) "relieved” and c) "folded” positioned.
  • Verzugsriemchen 27 are arranged, which are guided on deflecting rails.
  • FIG. 2 illustrates a schematized view from above of the drafting device 4, with the aid of which the arrangement of the components involved in the production process as well as the material flow resulting therefrom are explained.
  • the lower rollers 20A, 21A, 23A are covered by the upper rollers 20B, 21B, 23B.
  • the fiber material is fed to a drafting unit 4 upstream compressor 33, 33 'and then presented to the input roller pair 20. Between the input roller pair 20 and the middle roller pair 21, a further compressor 34, 34 'is provided.
  • the air spinning device 5 connects.
  • the fiber material flow is in Fig. 3 as dashed line F indicated. It can clearly be seen here that the fiber material flow F extends between the roller center of the top rollers 20B, 21B, 23B, 20B ', 21B', 23B 'and one of the top roller edges.
  • the adjacent air spinning devices 5, 5 ' have a pitch corresponding to the pitch of the drafting device 4 to each other.
  • the arrangement of the air spinning devices 5, 5 ' is selected such that the distance between the one air spinning device 5 to the central longitudinal axis M of the pendulum carrier 17 is greater than the distance of the adjacent air spinning device 5'.
  • the compressors 33, 33 ', 34, 34' are arranged in order to achieve an aligned material flow F through the drafting device 4 towards the air-spinning devices 5, 5 '.
  • top rollers 20B, 21B, 23B and 20B ', 21B', 23B ' has the greatest effect on the top rollers 23B, 23B' of the pair of output rollers 23. That by the delay Fiber material reduced to almost thread diameter creates a groove of appropriate width on top rollers 23B, 23B '. Since the wear due to the eccentric fiber material guide only in the edge regions of the upper rollers 23 B, 23 B 'occurs, interconnected by one axis 14 upper rollers 23 B, 23 B' can be taken out of the shuttle carrier 17 together, and rotated by 180 ° are used again ,
  • Fig. 4 represents a further embodiment in which the compressors 33, 33 ', 34, 34' on a traversing device 36, 36 'are arranged.
  • the traversing device 36, 36 ' serves to slightly change the compressors 33, 33', 34, 34 'and thus the fiber material between the roller pairs 20, 21, 23 in the region between the roller center and a roller edge.
  • the traversing device 36, 36 ' may be connected, for example, to a machine-length eccentric shaft which ensures uniform traversing of the compressors 33, 33', 34, 34 'transversely to the fiber material flow.
  • the traversing width is chosen so narrow that the deviation from the aligned feeding of the fiber material into the respective air spinning device 5, 5 'is so slight that the spinning process is not adversely affected.
  • the traversing width is less than half the roll width, but preferably less than 10 mm. The resulting deviation in the introduction of the drawn fiber material into the air spinning device 5, 5 'is in the range of less than tenths of a millimeter.
  • top rollers 20B, 21B, 23B, 20B ', 21B', 23B ' are detachable from their respective axles 14, 14', 14 "in order to re-open them on the opposite side the respective axis 14, 14 ', 14 "aufzustecken.
  • each upper roller 20B, 21B, 23B, 20B ', 21B', 23B ' is mounted on a separate axle 15, as in FIG Fig. 5 shown schematically.
  • both the top rollers of the axes 15 can be solvable or the top rollers 20B, 21B, 23B, 20B ', 21B', 23B 'are released together with their respective axis 15 of the pendulum carrier 17 and on the opposite side to the Axles 15 and arranged on the pendulum carrier 17.
  • This arrangement also allows at least the output top rollers 23B, 23B 'to be arranged in relation to the air-spinning units 5 in such a way that the material flow direction F is guided between the roller center and one of the roller edges.
  • At least the output top rollers 23B, 23B ' are arranged in relation to the air spinning units 5 in such a way that the material flow F deviates in each case in the same direction from the roller center. This ensures that, after release from the pendulum carrier 17 and the rotation of the upper rollers 20B, 21B, 23B, 20B ', 21B', 23B 'or the axes 14, 14', 14 ", 15 together with the upper rollers 20B, 21B thereon , 23B, 20B ', 21B', 23B 'are always the off-center portions of the top rollers 20B, 21B, 23B, 20B', 21B ', 23B' exposed to the material flow F, which have not been previously in contact with this, and thus also were not exposed to wear.
