Definitions

  • the present invention relates to a spinning box with interchangeable spindle for a spinning station of an air-spinning machine according to the preamble of patent claim 1.
  • the present invention relates to the field of air spinning machines.
  • Air-jet spinning machines have a multiplicity of spinning stations. In each spinning station, a yarn is spun from a fed longitudinal fiber structure. The fiber longitudinal structure is first refined, that is, the amount of fiber per unit length is reduced by delay. Then the refined fiber strand is spun by twisting into a yarn.
  • the yarn is produced today at very high speeds of about 600m / min in an air vortex, which is generated by compressed air nozzles supplied compressed air.
  • the typical situation shows in a perspective view the figure 1.
  • a fiber guiding element 20 leads the parallel oriented fiber structure 27 into the nozzle area 29, in which the solidification, i. the spinning of the yarn is done.
  • the quality of the spun yarn 25 is largely determined by the position and shape of the spinning tip. It is important for the yarn quality that the distance d between the spindle mouth 24 and the exit edge of the fiber guide element 20 is maintained very accurately. This must be ensured in particular after a change of the spindle 22 due to replacement or after cleaning.
  • the swirler 30, the spindle 22 and the other parts of a spinning box typically have manufacturing tolerances that can quickly reach within a range of ⁇ 0.3mm to 0.4mm.
  • a specific pairing made up of a respective swirler 30 and a spindle 22 to be able to maintain a predetermined distance d very accurately.
  • this is impractical in operation, since these pairs must be specially marked.
  • the present invention is therefore an object of the invention to provide a spinning box for a spinning unit of an air-spinning machine, in which a predetermined distance d between the spindle mouth and the trailing edge of the fiber guide element when re-inserting a spindle is maintained very accurate, the spindles are freely interchangeable and structurally simple should.
  • the stop plate is firmly connected to the swirl chamber housing at a defined distance relative to the fiber guide element and after which the spindle can be pressed with a bayonet lock to a stop surface of the stop plate; is a spin box created in which after insertion of the spindle and the fixation with the bayonet lock the spindle is in a defined and reproducible position relative to the vortex chamber and thus relative to the fiber guide element.
  • a bayonet closure is inexpensive to manufacture and the use of insertion and clamping does not require special tools or specialized knowledge.
  • the invention also allows a modular system of spin boxes formed of swirl chambers and associated spindles. Depending on the required yarn properties, it is possible to exchange the required spindle modularly and fix it with the bayonet lock without loss of precision.

  • the swirl element 8 in turn is pressed or glued into a cover 9.
  • the lid 9 is mounted by screws to the swirl chamber housing 28.
  • the spindle 22 is guided by a plastic part 3, which in turn is carried in the swirl chamber housing 28. It is therefore a plastic part, because it also has very good properties in terms of a guiding and sealing function.

Abstract

Dans un métier à filer pneumatique, la distance (d) entre un élément de guidage des fibres (20) et l'orifice de la broche (24) joue un rôle crucial pour la qualité du filé. Afin de pouvoir intégrer une broche (22.1, 22.2) de manière reproductible et exacte dans un logement à chambre de turbulence (28), ce dernier est équipé d'un système de fermeture à baïonnette (1, 1', 2).
