Definitions

  • the invention relates to a device for producing a spun thread from a staple fiber band, with a drafting system containing a plurality of roller pairs for drawing the staple fiber band into a fiber structure that can be predetermined, with an air nozzle unit that follows the drafting system and has an inlet opening for the fiber structure, and with a traversing device for traversing one the fiber assembly leading component transversely to the pairs of rollers of the drafting system, without causing the fiber assembly to escape transversely to the inlet opening of the air nozzle unit.
  • a device of this type is known from DE 31 45 208 C2.
  • the component guiding the fiber structure is a lower apron which carries out a traversing movement on its own - alternating with the assigned upper apron, if necessary.
  • the traversing speed of the known device should be so slow that the deviation of the fiber structure from the normal path is kept as low as possible, and in particular that the fiber structure does not have a meandering path so that the center of the fiber structure released by the last pair of rollers of the drafting system does not escape to the inlet opening of the air nozzle unit.
  • the latter requirement is met only incompletely, particularly when air nozzle units are used whose delivery speeds are up to 600 m per minute.
  • the lifespan of the apron is extended, whereas the wear on the covers of the drafting system is not reduced.
  • the invention is based on the object, on the one hand, to ensure that the fibers always enter the inlet opening in the same way, even at high delivery speeds, and, on the other hand, to extend the service life of both the covers and the apron of the drafting system.
  • the object is achieved in that the traversing device is connected in terms of drive both to at least one compressor assigned to a pair of rollers of the drafting system and determining the width of the fiber structure, and to the air nozzle assembly.
  • a safe fiber entry into the air nozzle unit is achieved, since this oscillates together with the fiber structure.
  • the wear on both the covers and the apron is reduced, especially if the traversing movement is carried out very slowly and the entire width of the covers is used.
  • the compressors oscillate in a manner known per se and form the component guiding the fiber structure, oscillating devices that have already proven themselves in practice can be used in principle, for example oscillating an inlet compressor and an intermediate field compressor. These compressors are in each case arranged upstream of the assigned roller pair, with no compressor usually being assigned to the output roller pair.
  • the at least one compressor and the air nozzle unit are arranged on a common carrier.
  • a thread cleaner arranged downstream of the air nozzle unit can also be arranged on this carrier.
  • the thread drawn from the air nozzle unit is also changed, so that wear is also reduced on the pair of draw-off rollers.
  • the traversing device itself can be designed differently.
  • the traversing device contains a traversing rod which runs along the machine and is assigned to a plurality of spinning stations. Since the pairs of rollers of the drafting unit are usually shut down in the event of thread breakage to avoid incorrect drawing, the traversing must also be stopped. In the case of a traversing rod running over several spinning stations, the traversing of a single spinning station must therefore be able to be decoupled from the general traversing movement if necessary. This can be achieved by a mechanism that clicks back onto the traversing rod after the spinning station has been put back into operation.
  • each spinning station is assigned its own traversing device, which is connected in terms of drive to the pair of input rollers of the drafting system.
  • the drafting system must be stopped if the thread breaks.
  • the traversing is automatically stopped when the drafting system is stopped.
  • FIG. 1 shows a side view of a device according to the invention
  • Figure 2 is a view in the direction of arrow II of Figure 1.
  • the device according to FIGS. 1 and 2 is used to produce a spun thread 1 from a staple fiber tape or also a roving 2.
  • the device contains a drafting device 3 and an air nozzle unit 4 as essential components.
  • the staple fiber tape 2 to be spun is supplied to the drafting device 3 in the direction of delivery A and is fed as a spun thread 1 in the take-off direction B to a winding device (not shown).
  • a pair of draw-off rollers 5, 6 serves to pull the thread 1 out of the air nozzle unit 4.
  • the drafting system 3 is designed as a three-cylinder drafting system and contains a total of three pairs of rollers 7,8; 9,10; 11, 12, each of which contains a lower roller and an upper roller.
  • the pair of rollers 7, 8 is the pair of input rollers
  • the pair of rollers 9, 10 is the middle pair of rollers provided with aprons 13 and 14
  • the pair of rollers 11, 12 is the pair of output rollers.
  • the staple fiber strip or roving 2 is drawn in a known manner to a desired, specifiable fineness. Following the drafting system 3, there is then a fiber structure 15 which is stretched but still untwisted.
  • roller speeds required for stretching are achieved in the present case by drive motors 16, 17 and 18, to which the respective lower rollers 8, 10 and 12 are connected.
  • the inlet roller pair 7, 8 is preceded by an inlet compressor 19 for the incoming staple fiber sliver or roving 2 and the middle roller pair 9, 10 by an intermediate field compressor 20.
  • the air nozzle unit 4 that follows the drafting system 3 at a short distance and gives the spinning rotation can in principle be of any design, but preferably a construction Art according to WO 02/24993 is addressed because such an air nozzle unit 4 allows particularly high delivery speeds.
  • the air nozzle unit 4 is therefore not described in detail.
  • it contains an inlet opening 21 for the fiber structure 15, furthermore a thread take-off channel 22 for the spun thread 1, that is to say provided with a spinning twist, and several pressure jet nozzles 23, which generate a swirling flow in a known manner.
  • a thread monitor is arranged downstream of the air nozzle unit 4, which in the present case is additionally designed as a thread cleaner 24.
  • Such thread cleaners 24 are known from the prior art. It is followed by the already mentioned pair of draw rollers 5,6.
  • the drafting system 3 With air spinning, delivery speeds of up to 600 m per minute can be achieved. In the drafting system 3, this leads to increased wear on the covers of the pressure rollers 7, 9 and 11 as well as the belt straps 13 and 14. So that the belt straps 13 and 14 do not have to be constantly replaced and the covers do not have to be reground at short intervals, the drafting system 3 is the Fiber structure 15 across the roller pairs 7,8; 9, 10; 11, 12 oscillates, as is already known in principle from the prior art. Care should, however, be taken to ensure that — as the prior art mentioned at the outset also strives for, even if only incompletely — the fiber assembly 15 is not brought out of alignment transversely to the inlet opening 21 of the air nozzle assembly 4.
  • the inlet opening 21 of the air nozzle unit 4 must be positioned very precisely to the outlet of the drafting system 3 and to the fiber structure 15 emerging from the drafting system 3. Even a slight displacement of the inlet opening 21 relative to the emerging fibers affects the thread quality and can even lead to a thread break. On the one hand, this is to ensure that the fibers always enter inlet opening 21 in the same way, and that on the other hand the lifespan of both the covers and the straps 13 and 14 is extended.
  • a traversing device 25 is now provided, which is driven by at least one compressor 19 or 20, which is assigned to a pair of rollers 7, 8; connected is. This ensures a safe fiber entry into the inlet opening 21 since the air nozzle unit 4 oscillates synchronously with the fiber assembly 15. At the same time, the fiber structure 15 is slowly moved over the entire width of the belt straps 13 and 14 and the covers of the rollers 7, 9 and 11, so that their service life is significantly extended.
  • both the two compressors namely the inlet compressor 19 and the intermediate field compressor 20, as well as the air nozzle unit 4 and the subsequent thread cleaner 24 are arranged on a common, oscillating carrier 26.
  • connecting elements 27, 28, 29 and 30 are used.
  • the traversing device 25 can contain a traversing rod 31 running along the machine and assigned to a plurality of spinning stations, as is preferably shown in the figures. This traversing rod 31 is moved very slowly in accordance with the traversing directions C and D, specifically over the greatest possible width of the coverings of the rollers 7, 9 and 11 or the running straps 13 and 14. If a thread breakage occurs for any reason, this is avoided the drafting system 3 is stopped by incorrect delays, that is to say the roller pairs 7, 8; 9, 10 and 11, 12 are stopped. In such a case, the traversing device 25 must also be stopped, which happens in the case of a central traversing rod 31 in that, in the event of a thread break, the affected one Single spinning station is decoupled from the general traversing movement by means not shown.
  • the traversing device 25 extends only individually over a single spinning station.
  • the traversing device 25 is automatically stopped as well.
