Definitions

  • the present invention relates to a spinneret for an air-jet spinning machine for producing a yarn from a fiber structure fed to the spinneret, the spinneret having an inner cavity in the form of an internal turbulence chamber which is at least partially outwardly delimited by a first spinneret section and a second spinneret section.
  • the spinneret sections are, in particular, housing sections of the housing delimiting the spinneret to the outside.
  • the first spinneret section comprises an inlet opening for the strand-shaped fiber structure and a number of air nozzles, via which air can be introduced into the turbulence chamber.
  • the spinneret is connected to a corresponding compressed air line after the installation of an air spinning machine.
  • the spinneret comprises a preferably spindle-shaped yarn-forming element that extends at least partially into the turbulence chamber and has an inlet for the fiber structure and an outlet for the yarn produced within the turbulence chamber in the region of the yarn-formation element during operation of the spinneret.
  • the inlet and the outlet are connected to a discharge duct running inside the yarn-forming element.
  • the yarn-forming element is held by the second spinneret section with the aid of a guide and can be moved between a spinning position and a cleaning position relative to the second spinneret section.
  • a method for cleaning a spinneret on an air-jet spinning machine which is used to produce a yarn from a fiber structure fed to the spinneret, is proposed, the spinneret in turn having an internal turbulence chamber which is at least partially outwards from a first spinneret section and a second spinneret section is limited towards.
  • the first Spinneret section has an inlet opening for the fiber structure and several air nozzles, via which air is introduced into the turbulence chamber during operation of the air nozzle.
  • the spinneret has a yarn-forming element that extends at least partially into the turbulence chamber and has an inlet for the fiber structure and an outlet for the yarn produced within the turbulence chamber in the region of the yarn-forming element during operation of the spinneret.
  • the method provides for the yarn-forming element to be moved from a spinning position into a cleaning position relative to the second spinneret section before or during the opening of the spinneret.
  • Generic spinnerets are used to produce a yarn from an elongated fiber structure with the help of a turbulent air flow generated by appropriate air nozzles within the turbulence chamber.
  • the outer fibers of the fiber structure are wound around the inner fibers (core fibers) in the area of the inlet of the generally spindle-shaped yarn-forming element, resulting in a yarn that is finally drawn off from the eddy chamber via the discharge channel of the yarn-forming element and with the help of a winding device can be wound onto a sleeve.
  • Corresponding spinnerets are, for example, from JP 2001 131834 A or the DE 10 2008 050 874 A1 known.
  • the spinneret housing surrounding the turbulence chamber in several parts.
  • the individual spinneret sections are mounted so that they can move relative to one another, so that the housing can be opened by moving one or more spinneret sections. After opening, the interior of the spinneret is accessible and deposits (avivage, honeydew, etc.) can be removed.
  • the object of the present invention is to improve a generic spinneret and to propose an improved method for opening or cleaning a spinneret.
  • the yarn-forming element is held by the second spinneret section with the aid of a guide.
  • the guide is preferably a component of the second spinneret section or is formed directly by it, for example with the aid of the bore, which will be explained in more detail later.
  • the guide is designed in such a way that the yarn-forming element can be moved relative to the second spinneret section and thus also relative to the first spinneret section. In particular, a movement from a spinning position to a cleaning position is possible.
  • the spinning position is that position which the yarn-forming element assumes during a spinning process, i.e. during the production of a yarn.
  • the cleaning position is a position that the yarn-forming element assumes when the spinning process has been interrupted and cleaning of the yarn-forming element or the turbulence chamber is desired.
  • the yarn-forming element is moved into the cleaning position in a direction away from the inlet opening of the spinneret.
  • the distance between the inlet opening and the inlet of the yarn-forming element is greater than in the spinning position.
  • the spinneret also includes a suction channel, which is preferably designed as an opening in a wall of the second spinneret section that delimits the vortex chamber to the outside.
  • the suction channel is connected to a vacuum supply, so that air can be sucked out of the turbulence chamber via the suction channel and thus also in the turbulence chamber or on the yarn-forming element adhering impurities.
  • air flows through the inlet opening of the spinneret into the vortex chamber.
  • the movement of the yarn-forming element from the spinning position to the cleaning position favors the suctioning off of impurities in the form of fiber residues, which wrap around the tip of the yarn-forming element having the inlet and negatively influence the spinning process.
  • the first spinneret section is attached to the second spinneret section via at least one pivot axis and can be pivoted about the pivot axis from a closed position into an open position.
  • the closed position is the position of the first spinneret section, which it assumes during the spinning process. In this position, the first spinneret section is in contact with the second spinneret section, so that the vortex chamber is closed to the outside by the two spinneret sections.
  • first spinneret section is pivoted from its closed position, it is in its open position.
  • the open position is understood to mean any position of the first spinneret section which deviates from the closed position. Furthermore, it is provided that the inlet of the yarn-forming element is accessible to an operator from the outside only in the open position, regardless of the position of the yarn-forming element (spinning position or cleaning position). If the first spinneret section is in its closed position, the tip of the yarn-forming element is not accessible from the outside and is protected.
  • the pivoting of the first spinneret section thus opens the spinneret as a whole, so that an operator from the outside can directly remove fiber residues from the tip of the yarn-forming element, which has the inlet. After this cleaning process, the first spinneret section can be pivoted back from its open position into the spinning position, so that the spinning process can be continued.
  • the first spinneret section can preferably only be pivoted relative to the second spinneret section.
  • the pivot axis is actively connected to the first spinneret section on the one hand and to the second spinneret section on the other hand.
  • both the first spinneret section and the second spinneret section have a receptacle into which the pivot axis extends.
  • the pivot axis does not necessarily have to be a bolt-shaped structure.
  • the pivot axis can be merely an imaginary axis about which the first spinneret section can be pivoted relative to the second spinneret section.
  • the two spinneret sections can be connected, for example, by a lug that enables the desired pivoting process.
  • the yarn-forming element can be moved relative to the second spinneret section exclusively linearly and preferably collinearly to a longitudinal axis of a discharge channel connecting the inlet of the yarn-forming element to its outlet.
  • the draw-off channel connects the inlet and outlet of the yarn-forming element and is used to guide the yarn during the spinning process. It is advantageous if the yarn-forming element, starting from its spinning position, can be moved at least 3 mm, preferably at least 5 mm, in the direction away from the inlet opening of the spinneret.
  • the yarn-forming element comprises a section surrounding the outlet, which is visible and/or tangible from outside the spinneret in every position of the yarn-forming element and also in every position of the first spinneret section.
  • the guide of the yarn-forming element is designed as a bore, with the yarn-forming element having a cylindrical outer contour in the region of the bore that corresponds to the bore and via which it is in contact with the guide.
  • the yarn-forming element thus bears against the inner wall of the bore, in particular via its outer contour, and is thereby guided in a movable manner in the axial direction of the discharge channel.
  • the spinneret has a force accumulator with the aid of which the first spinneret section is held in its closed position without external force, ie without an operator attempting to move the first spinneret section into its open position.
  • the first spinneret section remains in its open position only until the operator no longer exerts any force on the first spinneret section. away At this point in time, the energy accumulator causes the first spinneret section to move back into its closed position.
  • a magnet can also be present, which is firmly connected to the second spinneret section and is operatively connected to a surface section or other magnet of the first spinneret section, which is attracted by the magnet.
  • the magnet can also be arranged on the first spinneret section and interact with a surface section or other magnets in the area of the second spinneret section.
  • first spinneret section starting from its closed position, can be pivoted through an angle ⁇ into its open position, the amount of which is between 25° and 120°.
  • An angle of between 45° and 70° is preferred.
  • the first spinneret section has a connection for a compressed air line, via which the air nozzles can be supplied with compressed air.
  • the spinnerets are therefore preferably located entirely in the first spinneret section. Furthermore, there should be a cavity within the first spinneret section, which connects the individual spinnerets to the connection for the compressed air line.
  • a seal is arranged between the first spinneret section and the second spinneret section, through which the turbulence chamber is sealed airtight in the closed position of the first spinneret section in the area of the first spinneret section from the environment of the spinneret.
  • the seal is preferably a ring seal which is connected, for example, to the first spinneret section or the second spinneret section by a positive fit or with the aid of an adhesive bond.
  • the spinneret has a carrier via which it can be connected to a holding section of an air-jet spinning machine, the carrier being rigidly and preferably exclusively connected to or formed by the second spinneret section.
  • the carrier and the second spinneret section can be designed as a separate component. It is also possible for the second spinneret section to be designed in one piece with the carrier.
  • the carrier preferably has a bearing section, which can be formed by a bore, for example. Via the bearing section, the spinneret can be movably attached, for example, to a holding section of an air-jet spinning machine designed as a bolt. In this case, the spinneret can be moved, preferably pivoted, as a whole relative to other components of the air-jet spinning machine.
  • the method according to the invention is characterized in that the first spinneret section is attached to the second spinneret section via at least one pivot axis and is pivoted about the pivot axis from a closed position to an open position during the opening of the spinneret.
  • the inlet of the yarn-forming element is only accessible to an operator from the outside in the open position, regardless of the position of the yarn-forming element (spinning position or cleaning position), with the yarn-forming element being cleaned by an operator after the pivoting of the first spinneret section.
  • the section of the yarn-forming element that has the inlet is therefore protected from external influences inside the spinneret until an operator pivots the first spinneret section into the corresponding open position. In this position, the yarn forming element and in particular its inlet is accessible from the outside, so that adhering fiber residues or other impurities can be easily removed by the operator.
  • the first spinneret section is returned to its spinning position, either by the operator or with the aid of an energy store or magnet takes place as soon as the operator no longer exerts force on the first spinneret section.
  • the yarn-forming element is preferably first displaced relative to the second spinneret section. Subsequently or at the same time as this, air is sucked out of the turbulence chamber via a suction duct, which is preferably part of the second spinneret section, with air simultaneously flowing into the turbulence chamber via the inlet opening of the spinneret. As a result, fiber residues are already removed from the vortex chamber.
  • the turbulence chamber is subjected to a negative pressure via a suction channel of the spinneret when the yarn-forming element is in its cleaning position, in order to suck off fiber residues from the turbulence chamber, air from the environment being sucked into the turbulence chamber through the inlet opening of the spinneret will.
  • the first spinneret section can be pivoted into its open position relative to the second spinneret section and also relative to the yarn-forming element in order to enable an additional manual cleaning of the yarn-forming element or the turbulence chamber by an operator.
  • the first spinneret section is pivoted back into its closed position. Likewise, the yarn-forming element is moved back into its spinning position. After completion of the movements mentioned, the spinning process can be resumed.
  • the actuator can be one or more levers, for example act, which communicate with a portion of the yarn-forming element that is located outside of the second spinneret portion.
  • This section preferably comprises the outlet of the yarn-forming element and has, for example, a groove or a bulge communicating with the actuator.
  • a spinneret is used in the sense of the description of the device claims. It is also conceivable that the spinneret according to the invention has features that have been described exclusively in connection with the method.
  • figure 1 shows a cross-section of a spinneret 1 according to the invention, as used in air-jet spinning machines, which are known in principle from the prior art.
  • the spinneret 1 has a housing which comprises at least a first spinneret section 5 and a second spinneret section 6 .
  • the first spinneret section 5 and the second spinneret section 6 define an internal vortex chamber 4, into which a yarn-forming element 9 with an internal discharge channel 15 protrudes.
  • the yarn-forming element 9 is preferably designed to be rotationally symmetrical with respect to a longitudinal axis 14 shown only in FIG.
  • the guide 12 allows a linear movement of the yarn forming element 9 between the in figure 1 spinning position shown and in the figures 2 and 3 shown cleaning position.
  • the yarn forming element 9 is moved, for example, by an actuator 24, which is formed, for example, by one or more levers.
  • the first spinneret section 5 has a plurality of air nozzles 8 which are in fluid communication with a connection 19 via a corresponding connection, the connection 19 being designed to be connected to a compressed air line 20 of the air-jet spinning machine.
  • compressed air is introduced into the air nozzles 8 via the compressed air line 20 . Since these flow tangentially into the turbulence chamber 4 , a turbulent air flow occurs in the area of the inlet 10 of the yarn-forming element 9 , which causes the fibers of the fiber structure 3 introduced via the inlet opening 7 to rotate.
  • a yarn 2 is thus produced from the fiber composite 3, which yarn can be drawn off from the spinneret 1 via the discharge channel 15 and finally the outlet 11 of the yarn-forming element 9.
  • the air introduced via the air nozzles 8 escapes primarily via a suction channel 25, which is connected to a corresponding vacuum supply (not shown) of the air-jet spinning machine.
  • the spinneret 1 itself is preferably connected via a carrier 22, which is in particular rigidly connected to the second spinneret section 6, on a Mounted holding section 23 of the air spinning machine.
  • the movement of the yarn-forming element 9 increases the distance between its inlet 10 and the inlet opening 7 of the spinneret 1 or the first spinneret section 5 .
  • Fiber residues that have accumulated on the surface of the yarn-forming element 9 in the area of the inlet 10 can thereby be detached more easily from the yarn-forming element 9 and are finally sucked out of the spinneret 1 via the suction channel 25 .
  • the first spinneret section 5 can finally return to its closed position and the yarn-forming element 9 to its spinning position ( figure 1 ) are moved to close the vortex chamber 4 to the outside.
  • the movement of the first spinneret section 5 into its closed position can be brought about either manually by the operator or with the aid of an energy store 17 .
  • an energy store 17 in the form of a spiral spring is shown as an example, which holds the first spinneret section 5 in its closed position when there is no force applied or moves it back into this position if an external force is not applied in the open position of the first spinneret section 5.
  • one or more magnets 18 can be present (see FIG figure 2 ), which fix the first spinneret section 5 in its closed position in the absence of an external force.
  • a seal 21 for example in the form of a sealing ring, can be present between the first spinneret section 5 and the second spinneret section 6, via which the first spinneret section 5 rests airtight on the second spinneret section 6 in its closed position.
  • the first spinneret section 5 can also be pivoted through an angle ⁇ , the amount of which is preferably between 25° and 120°.
