Definitions

  • the present invention relates to a spinneret of an air spinning machine, which serves to produce yarn from a fiber structure by means of an air flow, wherein the spinneret has a, arranged within a housing of the spinneret, vortex chamber with an inlet opening for a fiber strand, wherein the spinneret at least one Partially extending in the vortex chamber Garnticianselement, wherein the spinneret comprises in the vortex chamber opening air nozzles, can be introduced via the air in the vortex chamber to impart rotation to the fiber structure in the region of an inlet opening of the Garnsentelements, wherein the Garnticianselement adjoining the inlet opening Has discharge duct, over which the yarn from the vortex chamber is removable, and wherein the spinneret is mounted such that it is reciprocable by pivoting between two positions.
  • Generic spinnerets are used to produce a yarn from an elongated fiber structure by means of a vortex air flow generated by corresponding air nozzles within the vortex chamber.
  • the outer fibers of the fiber composite are in this case wound in the region of the inlet opening of the generally spindle-shaped Garnsentelements around the inner fibers (core), so that in the result a yarn is formed, which finally withdrawn via the discharge channel from the vortex chamber and with the aid of a winding device to a Sleeve can be wound.
  • the surrounding surrounding the swirl chamber of the spinneret in several parts train.
  • the individual housing sections are in this case mounted to be movable relative to one another, so that the housing can be opened by moving one or more housing sections. After opening, the interior of the spinneret is accessible and can be freed of deposits (avivage, honeydew, etc.).
  • EP 3 168 340 A1 which according to Article 54 (3) EPC is state of the art, discloses a spinneret which is not pivotable between at least two positions, but wherein the two housing sections are slidable relative to one another via a linear guide.
  • the spinneret is characterized in that it comprises a housing with at least two housing sections delimiting the vortex chamber to the outside, wherein at least one of the housing sections is supported by means of a guide such that it is displaceable relative to a further housing section. If the housing section mounted with the aid of the guide is then displaced after pivoting of the spinneret relative to one or more further housing sections, the housing is moved from a closed position (which is to be assumed during yarn production) into an open position, in which at least the inlet opening exhibiting section of the Garn Strukturselements is accessible and cleanable for an operator.
  • the displacement of the mounted with the help of the guide housing portion relative to one or more housing sections in this case takes place along said guide, which is preferably designed like a rail.
  • the housing can of course also comprise a plurality of slidingly mounted housing sections, which are mounted displaceably relative to one or more further housing sections.
  • a displaceable housing portion is present, which is displaceable relative to a further housing portion, which is only to be understood as an example and the features described can be realized even with a spinneret with more than two housing sections.
  • the displacement of the movable housing section should take place along a guide, which comprises a guide track, in or on which a corresponding counterpart of the displaceable housing section is mounted in a form-fitting manner.
  • one or more stops should be present, which limit the movement of the respectively displaceable housing section in the region of desired end points of the displacement.
  • the spinneret as a whole is pivotable ⁇ by an angle which has an amount of 30 ° to 90 °, preferably from 40 ° to 80 °.
  • Such pivoting is particularly advantageous when a coil-side yarn end to be performed during a piecing against the actual spinning direction through the spinneret.
  • the yarn end is blown in this case by an air flow through the outlet opening of the discharge channel in this and / or sucked.
  • the yarn end is moved out through the extraction channel, through the inlet opening of the yarn formation element and finally through the inlet opening of the vortex chamber.
  • the spinneret comprises mechanical, pneumatic, hydraulic, magnetic and / or electromagnetically acting means with the aid of which the housing can be transferred from its closed position into its open position and / or vice versa.
  • one or more pneumatic cylinders could be used, by means of which the displaceable housing section is displaceable along the guide.
  • at least one spring is present, with the aid of which the displaceable housing section is pressed against a further housing section, so that the housing is held in its closed position by means of the spring until the displaceable housing with the aid of a pneumatic cylinder, an electromagnet or any other suitable means against the spring force of the spring is moved to transfer the housing in its open position.
  • the guide has one or more at least partially rectilinear and serving the leadership of one of the housing sections guide portions.
  • the guide is a linear guide or a guide, which is at least partially formed as a linear guide.
  • the rectilinear guide section may for example run parallel to a central axis of the discharge channel.
  • the guide or at least one guide section of the same part of the spinneret or part be a spinneret carrying the carrier of the air-spinning machine.
  • the guide may comprise a guide portion which engages around the guided portion of the displaceable housing portion in order to ensure a low-backlash guide.
  • the withdrawal channel has a central axis, wherein the extension of the central axis extends outside the inlet opening of the vortex chamber, when the housing has its closed position. This ensures that the rotation of the fiber composite produced in the region of the yarn formation element does not propagate outwards counter to the spinning direction (this would result in a negative impairment or even an interruption of the yarn production). In other words, the lateral offset of the discharge duct and inlet opening acts during the yarn production as a twist stop.
  • the yarn end can thus be particularly easily returned in the open position of the housing against the spinning direction through the spinneret, for this purpose only an air flow must be generated within the discharge channel, which is directed against the spinning direction and thus into the inlet opening of the vortex chamber.
  • the spinneret preferably has one or more injection nozzles, which open obliquely and counter to the spinning direction in the discharge channel and are in communication with a compressed air supply.
  • the guide has one or more at least partially curved and extending serving the leadership of one of the housing sections guide portions.
  • the displaceable housing portion can be tilted during its displacement relative to the further housing portion, so that the extension of the central axis of the discharge channel extends after the displacement of the bearing mounted by means of the guide housing portion in the inlet opening of the vortex chamber.
  • the housing section having the inlet opening of the swirl chamber is arranged in a first housing section and the yarn formation element is arranged in a second housing section, wherein one of the housing sections is displaceably mounted relative to the other is.
  • the housing has at least a first housing portion and a second housing portion, wherein the first housing portion along the guide is displaceable, and wherein the guide is rigidly connected to the second housing portion. A relative movement between the guide and the second housing portion is thereby safely avoided.
  • the guide is part of the second housing portion, so that a separate attachment of the guide can be omitted on the second housing portion.
  • the pivotable housing portion can be pivoted as part of the spinneret.
  • it can be pivoted in addition to the said pivoting with respect to a further housing portion, so that two independent pivoting movements are possible.

  • the displaceable housing section starting from the spinning position of the spinneret, can first be pivoted as part of the spinneret, subsequently displaced along the guide and finally pivoted relative to a further housing section.
  • the displaceable housing section can therefore occupy three positions, wherein the last-mentioned position permits particularly good accessibility of the yarn-forming element.
  • the spinneret are pivotably mounted about a first pivot axis and the pivotable housing portion about a second pivot axis, wherein the first pivot axis is arranged spaced in a direction perpendicular to the first pivot axis direction of the second pivot axis.
  • the position and the individual directions of movement of the housing section which can be pivoted twice can be adapted particularly easily to the given space conditions in the air-spinning machine.
  • the two pivot axes are parallel to each other.
  • the pivotable housing section is mounted on a carriage and can be pivoted relative thereto, the carriage in turn guided by means of the guide and being displaceable along the guide.

  • the inventive method for opening a spinneret of an air spinning machine is characterized in that the spinneret is pivoted and that in the course of this movement or subsequent thereto opening of the housing takes place by one of the housing sections is moved relative to a further housing portion, wherein the shifting such takes place that after moving the corresponding housing portion, at least the portion of the Garn avoirselements having the inlet opening is accessible and cleanable for an operator.
  • At least one housing section is therefore initially pivoted as part of the spinneret during the opening process and then displaced along a guide (wherein the spinneret or its components can be designed according to the preceding or following description).
  • the displacement of the displaceably mounted housing section takes place along an at least partially curved guide track (reference being made to the above description with regard to the relevant advantages).
  • a pivoting of a housing section relative to a further housing section takes place in order to further improve the accessibility of said section of the yarn-forming element.
