Definitions

  • the invention relates to a spinning station of an air-jet spinning machine with a cleaning device for a yarn-forming element and a method for cleaning such a yarn-forming element.
  • air-jet spinning involves drawing a sliver to a defined yarn count using a multi-roller drafting system, depending on the desired yarn count, and then feeding it to an air-jet spinneret.
  • the outer fibers of the sliver are wound around an inner fiber core by means of a swirling air flow generated by air jets in the area of an inlet opening of a yarn-forming element of the air-jet spinneret.
  • the wrapped fibers are crucial for the desired strength of the yarn. There are clear limits to the number of fibers required in the cross-section to achieve sufficient strength, which is why conventionally spun air-jet yarns typically have a count range of Ne 20–50.
  • the EP2767625A1 discloses a method for cleaning a yarn forming element of an air spinneret with an additive.
  • the spinning station of an air-jet spinning machine has a feed for a fiber sliver to an air-jet spinneret, the air-jet spinneret with a fiber sliver inlet for the inlet of the fed fiber sliver into the air-jet spinneret, a vortex chamber arranged inside the air-jet spinneret for generating a vortex air flow by means of at least one vortex air nozzle opening into the vortex chamber, at least one yarn-forming element arranged inside the vortex chamber for producing a yarn from the fiber sliver fed into the vortex chamber of the air-jet spinneret via an outlet of the fiber sliver inlet, a withdrawal channel extending through the yarn-forming element for withdrawing the air-jet spun yarn, and a cleaning device.
  • the cleaning device encompassed by the spinning station has a cleaning ribbon and a storage unit for providing and retracting the cleaning ribbon.
  • a fixed end of the cleaning ribbon is secured to the storage unit, in particular detachably and fixably for replacing the cleaning ribbon, and a free end of the cleaning ribbon is provided for cleaning the yarn-forming element, in particular unrollable, and can be retracted again after cleaning, in particular rolled up.
  • the cleaning device has a cleaning ribbon guide for feeding the free end of the cleaning ribbon for mechanically cleaning a surface of the yarn-forming element of the air spinneret.
  • a free end of a cleaning ribbon is first fed from a cleaning device through a withdrawal channel of a yarn-forming element into the swirl chamber of the air-jet spinneret, in particular to an outlet of a fiber sliver inlet leading into the swirl chamber, through which the fiber sliver is introduced into the air-jet spinneret and into the swirl chamber.
  • a mechanical cleaning of components inside the vortex chamber of an air spinneret can be carried out in a particularly simple manner, wherein it is particularly advantageous that it is not necessary to open the air spinneret, so that the cleaning can be carried out particularly quickly and without disruption.
  • An air spinneret is understood to be any spinneret which, by means of at least one air stream, spins fibres, in particular wrapped fibres, around an internal fibre core to form a Thread or yarn is swirled.
  • the yarn formation process takes place in the area of a swirl chamber of the air-jet spinneret, in which at least one yarn-forming element is arranged.
  • the air-jet spinneret is surrounded by a spinning station, with each spinning station serving to produce a yarn from a fiber sliver fed to the air-jet spinneret of the spinning station.
  • the vortex chamber is located behind the fiber sliver inlet in the transport direction of the fiber sliver, or the fiber sliver inlet forms a feed opening or an outlet for the fiber sliver to be fed to the vortex chamber on a side facing the vortex chamber.
  • a yarn or thread within the meaning of the invention is a fiber strand in which at least some of the fibers are wound around an internal fiber core.
  • a yarn can also be a roving or sliver for further processing, for example, using a ring spinning machine.
  • the fiber strand and thus the yarn produced therefrom are preferably formed at least partially, particularly preferably entirely, from synthetic fibers or chemical fibers, for example, from polyester or polyethersulfone.
  • the sliver is basically the sliver fed into the air spinning process.
  • Fiber material that is preferably provided as a coherent ribbon or composite of fibers to be spun. All fibers can be made of the same material, or the fiber ribbon can contain chemically different fibers. However, the fibers in the fiber ribbon are generally not yet spun together.
  • the yarn-forming element can be a standalone component, a section of a structural unit, or a functional unit directly involved in the air-jet spinning process.
  • the yarn-forming element can be formed in one piece or in multiple pieces.
  • the yarn-forming element preferably comprises a spinning cone or part of a spinning cone. Most preferably, the yarn-forming element forms the spinning cone.
  • the yarn-forming element comes into direct contact, at least in sections, with the fibers to be spun to produce the yarn, as well as with the spun yarn.
  • a cleaning device is basically any device by means of which a yarn-forming element of an air-jet spinneret of an air-jet spinning machine can be mechanically cleaned.
  • the mechanical cleaning preferably involves mechanically rubbing the surface to be cleaned inside the air-jet spinneret using the cleaning ribbon.
  • the mechanical cleaning can also be additionally supported by a chemical cleaning medium, preferably a cleaning fluid, and particularly preferably an aqueous cleaning solution, on the cleaning ribbon. It is also conceivable to introduce a suitable chemical cleaning medium, in particular a cleaning fluid, into the vortex chamber and, in particular, onto the surfaces to be cleaned to support the mechanical cleaning by the cleaning ribbon.
  • the cleaning ribbon is preferably formed from a fiber material and/or has a rough surface to assist mechanical cleaning. Furthermore, the cleaning ribbon is flexible enough that the end of the cleaning ribbon inserted into the air spinneret for cleaning can be moved, in particular repeatedly, over the surfaces of the air spinneret to be cleaned, in particular the yarn-forming element and/or a nozzle orifice of the swirling air nozzle, due to the swirling air flow. Particularly preferably, the cleaning ribbon is formed such that it can be guided, in particular repeatedly, over a spinning cone tip, over at least one nozzle orifice of the swirling air nozzle, and/or over a surface of a discharge channel by means of the swirling air flow.
  • An arrangement in the area of a yarn preparation unit is particularly advantageous, since the yarn preparation, which is otherwise intended to receive one end of a spun yarn, can also receive the free end of the cleaning ribbon in a particularly simple manner and can guide this in the same way as a yarn end into the interior of the air spinneret, in particular into the swirl chamber, in particular up to the exit of the sliver inlet. Accordingly, it is also preferred that the feeding of the free end of the cleaning ribbon, in particular up to the exit of the sliver inlet, takes place by means of a fiber guide element.
  • a preferred development of the method for cleaning a yarn forming element provides that the drawing-in takes place with a vortex air flow switched on in order to remove deposits and/or to better clean the surface of the extraction channel, since with a vortex air flow switched on, a movement and/or swirling of the cleaning ribbon also occurs during drawing-in.
  • the swirling air flow in the swirl chamber is preferably generated with or after the free end of the cleaning ribbon exits the discharge channel or with or after the free end enters the swirl chamber. This ensures effective and reliable cleaning of the area around the discharge channel opening of the yarn forming element within the swirl chamber. Furthermore, this allows reliable the guidance of the free end of the cleaning ribbon within the vortex chamber along the surface of the yarn forming element is made possible.
  • the cleaning ribbon can also be cleaned during or after retraction into the cleaning device in order to at least partially clean the cleaning ribbon and extend its service life.
  • a preferred embodiment of the method for cleaning a yarn forming element provides for cleaning of a yarn forming element during a spinning interruption, for example after at least one or each thread break, after at least one or each yarn cut, during removal of a package wound using the air-jet spun yarn and/or during a spinneret change from which the sliver is fed to the spinning station. Cleaning after a thread break makes it possible, in particular, to remove contamination as a possible cause of thread break before the air-jet spinning process is resumed.
  • Cleaning after a yarn cut, during removal of the package or insertion of a new empty tube into the winding device and during a spinneret change ensures consistently high yarn quality and strength.
  • cleaning can also be carried out periodically with defined intervals that are the same or different from each other, in particular with regard to the operating time of the spinning station, the number of thread breaks, the The number of yarn cuts, the number of bobbin removals or the number of empty tubes inserted, the number of spinning can changes, and generally the number of spinning interruptions or stops must be taken into account to ensure regular cleaning and to avoid longer periods without cleaning.
  • the fiber sliver can be fed via a central fiber sliver storage device assigned to the air-jet spinning machine or via a respective fiber sliver storage device assigned to the individual spinning station, such as in particular a sliver can, in which a defined amount of fiber sliver is deposited so that it can be removed from the sliver can.
  • the work station can have further fiber sliver or thread treatment devices for the defined and needs-based treatment of the fiber sliver or thread.
  • the workstation can be equipped with sensors for monitoring the sliver feed and/or the sliver parameters, as well as, or alternatively, for monitoring the yarn take-off, the yarn feed to the winding device, the yarn parameters, for cleaning yarn defects, and/or for piecing after a sliver or yarn break or after a sliver can change or a package removal.
  • the workstation can be assigned sensors or other devices in the area of a drafting system comprising the sliver feed, by means of which the sliver can be defined and drawn as required and/or provided with additional fibers, in particular made of a different fiber material, a so-called core yarn.
  • a Figure 1 The fiber sliver 11 is fed into the purely schematically illustrated air-jet spinneret 12 in the region of a feed 10.
  • the fiber sliver 11 passes through an outlet 13 of a fiber sliver inlet 16 into a vortex chamber inside the air-jet spinneret 12 and is spun there into a yarn 14 by means of a vortex air flow on a yarn-forming element 2 formed as a spinning cone.
  • the outer fibers of the fiber sliver 11 are wound around an inner fiber core by means of the vortex air flow generated by the vortex air nozzles, resulting in an air-yarn-specific yarn structure with a parallel yarn core and wrapped fibers arranged at a specific angle.
  • the spun yarn 14 is drawn off from the air-jet spinneret 12 through a take-off channel 15 in order to be fed to a downstream thread handling device, such as a winding device, for forming a package.
  • a fiber sliver 11 made of synthetic fibers, in particular polyester fibers is used in air spinning, deposits of fiber fragments and finishing agents may occur on the surface of the yarn forming element 2 or on the surfaces of the walls of the vortex chamber of the air spinning nozzle 12 surrounding the yarn forming element 2 during the air spinning process, which in the long term lead to a deterioration of the spinning result and thus to reduced yarn strength and quality.
  • a cleaning device 1 is arranged in the yarn take-off direction behind the take-off channel 15 and in the area of a thread preparation unit of the spinning station 9. Inside a storage unit 4 of the cleaning device 1, a cleaning ribbon 3 is wound onto a storage spool 8.
  • the cleaning ribbon 3 is attached to the storage reel 8 by a fixed end 5, allowing it to be repeatedly removed and fixed.
  • the free end 6 of the cleaning ribbon 3 can be removed from and retracted from the storage unit 4 by unwinding and rewinding the storage reel 8.
  • the cleaning ribbon 3 is made of a fiber material and has a rough surface.
  • the cleaning device 1 In order to be able to feed the cleaning ribbon 3 to the air spinneret 12 after it has been rolled out of the storage unit 4, the cleaning device 1 finally has a cleaning ribbon guide 7, which is formed by further components of the spinning station 9, in particular a thread preparation unit.
  • the air spinning process is interrupted and then, with the air spinning nozzle 12 still closed, the free end 6 of the cleaning ribbon 3 is guided by means of the cleaning ribbon guide 7 into the area of the outer opening of the discharge channel 15 (see Figure 2 ).
  • the free end 6 of the cleaning ribbon 3 is guided into the take-off channel 15 by means of the thread preparation and from there advanced into the interior of the vortex chamber in the direction of the outlet 13 of the fiber sliver inlet 16.
  • the free end 6 of the cleaning ribbon 3 is moved repeatedly against and around the surface of the yarn-forming element 2, which is formed as a spinning cone.
  • the free end 6 of the cleaning ribbon 3 can also be guided past the nozzle openings of the vortex air nozzles, with particular cleaning taking place in the area of the tip of the yarn-forming element 2 and in the area of the nozzle openings.
  • the movement of the free end 6 caused by the swirling air flow continues along the cleaning ribbon 3 in the direction of the fixed end 5 in such a way that the surface of the discharge channel 15 within the yarn-forming element 2 is also cleaned.
  • the fixed end 5 of the cleaning ribbon 3 is rotatably mounted about the extension axis of the cleaning ribbon 3 in such a way that an undesirably strong twisting of the cleaning ribbon 3 can be avoided by propagating the movement of the free end 6 in the direction of the fixed end 5.
  • the cleaning ribbon 3 is removed from the interior via the discharge channel 15 the air spinneret 12, whereby a repeated cleaning of the surface of the discharge channel 15 takes place.
  • the cleaning ribbon 3 is rolled back onto the storage spool 8 inside the storage unit 4.
