Definitions

  • the invention relates to a pneumatic device for producing a spun Thread from a fiber composite by means of a vortex flow.
  • a pneumatic spinning device is known from DE 41 05 108 (henceforth DE'108) is used to produce a thread from a short fiber sliver.
  • the fibers are in a nozzle block that has a cavity with a conical inside Has supporting body, subjected to a rotating air flow and so for rotation causes them to form a thread.
  • the thread becomes one through a spindle channel subtracted substantially opposite the conical support body.
  • a fiber guide channel opens from the outside into the nozzle area. This fiber guide channel is used to feed the Fibers, respectively. of the sliver, from the outside into the cavity.
  • DE 40 36 119 Another pneumatic spinning device is known from DE 40 36 119 (henceforth DE'119) which is used to make a thread from short fibers.
  • This device also has a nozzle block.
  • the Operation of this arrangement is otherwise largely analogous to that in DE'108 shown and is therefore not explained here.
  • this device has the disadvantage that the yarn quality can practically not be controlled. Due to the uncontrolled air flow, especially in the cavity and the area in to which the sliver is fed, the fiber quality is difficult to control.
  • the invention disclosed here shows a pneumatic spinning device which is used to produce a spun thread from staple fibers.
  • a nozzle block contains a cavity inside with jet nozzles.
  • a fiber guide means is arranged coaxially with respect to an essentially cylindrical spindle, which passes into or arises from a fiber guide channel.
  • the fiber guide channel opens from the outside into the cavity and is used to feed fibers, respectively. a sliver, for example from a delivery plant.
  • the design and the arrangement of the fiber guide channel and the fiber guide means is of considerable importance for the resulting quality and the properties of the yarn.
  • the fiber feed channel is advantageously designed taking aerodynamic aspects into account.
  • the spindle arranged opposite the fiber guiding means is fixed or rotating and has an essentially centrally running spindle channel, which serves to guide the spun thread away.
  • the fiber guide channel is advantageously offset laterally with respect to the spindle.
  • the sliver running out of a supply plant is introduced into the cavity through the fiber guide channel.
  • the fibers of the fiber band are exposed to a rotating, spiral-shaped air flow which is generated by the jet nozzles arranged essentially tangentially to the spindle and the fiber guiding means.
  • the fibers are directly exposed to the rotating air flow around the fiber guide, which exerts a force separating the fiber sliver on fiber ends that are not guided in the spindle channel.
  • the arrangement of the spindle, the fiber guide means and the fiber guide channel are selected so that the leading fiber end part (fiber end part that first enters the opening of the spindle channel) of the fibers already form part of the yarn, while the trailing end (fiber end part that does not go first into the Opening of the spindle channel occurs) of the fibers is lifted by the force acting outwards.
  • This trailing free end of the fibers is arranged to rotate around the spindle in a substantially spiral-jet fashion due to the air flow.
  • the fibers are gradually drawn into the spindle channel, spiraling around the fiber guiding means, so that a spun thread with real rotation is created.
  • the fibers can pass through the fiber guide channel it is difficult to loop the supplied sliver around each other in an uncontrolled manner.
  • the fiber guide also acts as a so-called false core, which, together with the The propagation is designed and arranged according to the invention controlled the rotation during thread formation. This avoids that Fibers are rotated incorrectly, resp. a false twist from the fiber guide means backwards against the fiber guide channel towards the delivery plant, which is a real turning of the fibers would at least partially prevent and affect the yarn quality.
  • the fiber guide channel and the fiber guide means preferably have one continuous, aerodynamic course and depend on what can be achieved Effect, symmetrical or asymmetrical, tapered or bulbous. Other Shapes and arrangements of the fiber guiding means are possible.
  • the design and arrangement of the fiber guide channel in which the fiber sliver or the fibers from the delivery plant is introduced into the cavity in the nozzle head, has a significant influence on the processing process and the resulting yarn.
  • the fibers of the fiber ribbon are prepared for the spinning process by aligning and arranging them before they enter the cavity and are exposed to the rotating air flow.
  • the design and the cross-sectional profile of the fiber feed channel determine how the fiber sliver and the fibers are shaped and prepared.
  • the channel is designed in such a way that a controlled air flow prevails in its interior during operation, which is directed into the nozzle head from the outside and specifically influences the orientation and arrangement of the fibers.
  • the fibers are fed to the process in a more curled or stretched manner, as a result of which yarns with different properties are produced.
  • the design and arrangement of the channel also influences the rotation of the fibers in the spinning process and the fiber guidance.
  • the consistency of the yarn quality is optimized through a deliberate design of the fiber guide channel and the prevailing flow conditions.
  • the design of the duct cross-section influences the air flow, the pressure curve in the duct and the fiber distribution. Through targeted guidance of the flow and, if necessary, controlled vortex formation, an unwanted twisting of the fibers, in particular in the fiber guide channel, is avoided.
  • the fiber guide channel advantageously has a flowing course without abrupt changes in cross-section. Corners and edges that create negative currents, especially stalls and turbulence, are avoided.
  • the fiber guide channel advantageously merges smoothly into the fiber guide means without abrupt transitions.
  • the fiber guide channel can have a multi-part at least in some areas Have cross-section and with additional fiber guide means, such as Ribbed slats or recesses that prevent twisting of the fibers.
  • the air flow in the fiber guide channel is, if necessary, determined by specific Guidance means, e.g. in the form of lamellas or profiled, the flow through Controlled and directed elements influencing pressure differences.
  • the fiber guide channel has a variable channel cross section. This is designed in such a way that the fibers to be processed are specifically transformed and used for the Spinning process to be prepared.
  • the fiber guide channel preferably has at least in some areas a cross-section on the oval, circular, semicircular, circular segment, kidney, is heart-shaped, sickle-shaped or crescent-shaped, or along its length or in a cross section has a combination of these or other shapes. Longitudinal, trenches or protrusions integrated into the cross section are also suitable.
  • the course of the area of the channel cross section is particularly relevant. Through it can, among other things the pressure course and the course of the flow velocity are determined locally become.
  • additional fluid sources or fluid sinks e.g.
  • the flow becomes nozzles which open (are arranged) in the fiber guide channel If necessary, specifically influenced and influenced the fiber transformation.
  • the length of the fiber guide channel is at least in certain areas depending on the requirements a continuous (steady) course, such that no negative Turbulence and stalls arise.
  • the wall of the fiber guide channel preferably flows smoothly and without abrupt changes in direction in the fiber guide about.
  • the fiber guide means advantageously extends into the fiber guide channel or connects to it.
  • the yarn formation occurs after the start of a piecing process of any kind, for example by pulling an end of an already existing yarn back through the spindle channel of the spindle is guided so far into the area of the spindle inlet opening is that fibers of this yarn end are opened so far by the already rotating air flow that the newly fed through the fiber guide channel leading ends of Fibers can be captured by this rotating fiber structure and by again pulling the inserted yarn end can be held in it that the subsequent rear parts of the newly supplied fibers are around the wind around the front ends already in the mouth part of the spindle channel can, so that the above-mentioned yarn with a substantially predetermined Piecer can be spun again.
