Definitions

  • the invention relates to a spinning machine comprising a plurality of spinning stations, each having a drafting device, a pneumatic compacting device and a swirl generating device for at least one fiber strand, wherein a plurality of such devices are arranged side by side in the spinning machine, and the compacting means an evacuated compacting surface for compacting over the compacting surface guided fiber strand and a suction device, via which the suction air flowing through the evacuated compression surface into the suction device is discharged.
  • Spinning machines in particular ring spinning machines, with pneumatic compression devices are known from the prior art.
  • the pneumatic compression device serves the purpose of compressing a stretched fiber structure, wherein edge fibers protruding from the fiber structure by exerting an induced draft are guided towards the fiber structure and the fiber structure is generally compacted. Thanks to the pneumatic compaction process, a fine yarn of low hairiness can be produced.
  • the suction insert is connected to a suction line, via which an induced by a vacuum source induced suction is applied.
  • the compaction effect is achieved by ambient air through the openings in the outer circumference of the screen drum and the suction slot of the underlying suction insert is sucked into the suction line.
  • Object of the present invention is therefore to propose a device by means of which a reduced or absent suction at the compression surface of the compacting device easily detected and can be corrected quickly, so that the quality of the yarn produced is impaired as little as possible.
  • the suction device are associated with negative pressure indicating means for optically displaying a negative pressure or induced draft at the respective spinning station and thereby reduced compression suction power
  • the negative pressure indicating means comprise a display element and return means acting on the display element, wherein the negative pressure the display element exerts a force, and the restoring means exert a negative pressure on the display element, and the negative pressure and the return means cooperate with each other such that when the negative pressure or the induced draft or when a negative pressure threshold or induced draft, the display element changes its shape due to the restoring force of the return means.
  • the display means comprise a shape-changeable body on which a suction or negative pressure is exerted, which causes a change in the shape or the size of the body.
  • the body or parts thereof have a resilience, which counteracts the induced draft or negative pressure, so that when the negative pressure or the induced draft decreases, the shape of the body is continuously or abruptly changed due to the restoring forces acting on the body.
  • the body or parts thereof consists of a flexible material with resilience.
  • the body is dimensionally stable under atmospheric pressure conditions and variable in its form or size when exerting a suction or negative pressure.
  • the flexible material may, for. B. rubber-elastic or elastic properties have, which exert a counter to the negative pressure or the induced draft restoring force on the shape-changeable body.
  • the display means include a variable-shape hollow body which is attached to the suction device, such that in its cavity an induced draft is exerted by means of which the shape or size of the hollow body is changed.
  • the nature of the hollow body is such that when the negative pressure or the induced draft, the shape of the hollow body is changed due to the restoring forces acting on the hollow body.
  • the change in shape is preferably in an expansion, bulging or unfolding of the hollow body walls, ie in an increase in the volume of the body due to the restoring forces acting on the body.
  • the hollow body is preferably dimensionally stable under prevailing atmospheric pressure conditions inside and outside the hollow body.
  • the hollow body is preferably in the form of a cylindrical bellows whose Faltenbalg Vietnamese has a resilience.
  • the bellows folds together reducing its volume.
  • the bellows unfolds under volume increase due to the acting restoring forces in Zylinderachsraum. In this way, a malfunction is visually displayed in the area of the compression area.
  • the hollow body may also be a balloon-shaped body, the shell of which has a resilience, which counteracts the negative pressure or the induced draft, so that upon removal of the negative pressure or the induced draft, the balloon envelope unfolds or bulges outwards.
  • the display element is in the form of a dome-shaped membrane which has a resilience counteracting the negative pressure or the induced draft, so that the membrane is everted when the pressure falls below a limit value for the negative pressure or for the induced draft ,
  • the resilience is justified by an axial bias of the membrane.
  • the membrane has at its triggered by changing the negative pressure or the induced draft change a Umspringtician or Umschlagtician ("mechanical dead center”), in which the membrane jumps from a concave shape into a convex shape.
  • the membrane is designed and arranged on the suction device, that it is formed concave inward when the induced draft from the outside and absent or too low suction convex outwards. While an outside observer scarcely perceives the concave curvature of the membrane, it immediately catches the convexly outwardly convex membrane when the induced draft disappears.
  • the perception can be enhanced by a coloring of the membrane by a striking signal color.
  • the compacting device may include a rotatable compacting drum having a preferably annular cavity and a peripheral surface forming the compacting surface and provided with apertures.
  • the suction device comprises a suction insert with suction opening, which is introduced into the cavity of the compression drum and stored therein stationary.
