Definitions

  • the invention relates to an air spinning device with a spindle according to the preamble of the independent claims.
  • a yarn spinning device or a roving spinning device is to be understood, wherein the proposed device for all spinning processes which work with air can be used.
  • a spinning device which serves to produce a yarn by means of an air flow comprises a sliver feed, a drafting device, an air spinning device and a take-up device.
  • a sliver is fed from a fiber sliver storage presented to a drafting system.
  • the sliver is stretched under a certain delay and passed on to the air spinning device.
  • the stretched sliver is fed via a fiber guide element of a vortex zone.
  • the vortex zone is a space between the fiber guide element and the inlet opening in a spindle opposite the fiber guide element.
  • the vortex zone is arranged in a nozzle body in which the fiber guide element is inserted from one side and a spindle from the opposite side.
  • the fiber guide element is inserted from one side and a spindle from the opposite side.
  • Into the vortex zone we introduce compressed air through correspondingly arranged holes, which through the arrangement of the bores leads to the formation of a vortex, which is discharged outside along the spindle. Due to the turbulence of the introduced compressed air, a part of the fibers of the introduced into the air spinning device sliver is removed from the sliver and folded around the spindle tip around. The fiber ends are trapped in the non-dissolved fibers of the sliver and are drawn into the spindle with these so-called core fibers.
  • the Umwindemaschinen be wound around the core fibers due to the vortex flow. Due to the design of the individual components and the settings of the vortex air, various properties of the spinning process can be influenced. For example, the number of wraps compared to the core fibers may be changed, or the number of wraps per length or yarn twist of the finished yarn can be adjusted. Under the yarn twist is the angle to understand under which the Umwindemaschinen in relation to the longitudinal axis of the yarn wrap around the core fibers. In this way, it is possible to produce yarns with different properties in the air spinning process, for example, roving.
  • roving is meant an intermediate which is used as a starting material for final spinning processes, such as ring spinning or rotor spinning.
  • final spinning processes such as ring spinning or rotor spinning.
  • the EP 2 009 150 A1 discloses an air-spinning device having a nozzle body and a hollow spindle.
  • the spindle protrudes with its spindle tip into the nozzle body.
  • an annular discharge channel is formed between the outer surface of the spindle tip and the inner surface of the nozzle body.
  • the discharge channel has a cylindrical shape and the distance between the inner surface of the nozzle body and the outer surface of the spindle is constant.
  • This gap width is constant over the course of the spindle longitudinal axis, whereby the cross-sectional area normal to the longitudinal axis of the spindle is constant over the course of the longitudinal axis of the spindle.
  • EP 2 009 150 A1 discloses a specific range for the dimension of the gap width and the inner diameter of the nozzle body. Apart from the dimensions of the spindle tip and the nozzle body and thus the definition of the discharge channel, the shape of the discharge channel is crucial for the behavior of the vortex air flow. Due to the cylindrical shape of the discharge channel, the fluidizing air can flow unhindered along the spindle tip. In this case, short fibers are detected by the flow and carried away from the spindle tip of the outflowing air.
  • a disadvantage of the disclosed air spinning device is also that the yarn twisting can be influenced only by a reduction in the swirling air, with the result that a reduction of the swirling air at the same time leads to a reduction in the number of the Umwindemaschinen, while the amount of waste usually increases, since the fibers are bad integrated.
  • the object of the invention is to avoid the disadvantages of the prior art and to provide an air spinning device which allows minimization of the departure and thus a better utilization of raw materials and simplifies adjustment of the yarn rotation.
  • an air spinning device with the characterizing features of the independent claims.
  • the object is achieved in that an air spinning device is provided with a nozzle body and a hollow spindle with a spindle tip and a longitudinal axis, wherein the spindle tip protrudes into the nozzle body and between a outer surface of the spindle tip and an inner surface of the nozzle body, a drain channel with an annular cross-sectional area forms and a normal to the longitudinal axis of the spindle seen gap width at a certain point of the discharge channel over the circumference of the spindle is constant.
  • the outer surface of the spindle tip and / or the inner surface of the nozzle body is shaped such that in the discharge channel in its course in the direction of the longitudinal axis of the spindle at least two bottlenecks in the discharge channel is formed, the discharge channel in its course in the direction of the longitudinal axis of the spindle each of these constrictions has an annular cross-sectional area that is smaller than the annular cross-sectional area of the bleed passage before and after each of these at least two constrictions.
  • the invention is basically applicable to any air-spinning machine, irrespective of the type of yarn or roving to be produced, in which at least part of the fibers in the cross-section of the process product has a rotation and the machine therefore has an air-spinning device with a hollow spindle and a nozzle body.
  • air spinning devices In air spinning for making a yarn or roving by wrapping core fibers with wraps, air spinning devices are used which comprise a hollow guide spindle and a nozzle body.
  • a Garn arrangementskanal In the spindle a Garn arrangementkanal is provided, which opens with a spindle opening in the spindle tip.
  • a fiber sliver to be spun is introduced into the nozzle body via a fiber guide element arranged upstream of the spindle.
  • the spindle protrudes with its tip into the nozzle body, wherein a discharge channel with an annular cross-sectional area forms between an outer surface of the spindle tip and an inner surface of the nozzle body.
  • a vortex zone is formed between the fiber guide element and the spindle tip.
  • the fibers introduced into the air-spinning device by the fiber guiding element are divided by the turbulent flow into core fibers, sheath fibers and fibers, the core fibers being introduced directly into the spindle opening, the sheath fibers being trapped at one end in the core fibers and transferred at the other end via the spindle tip and the outlet is discharged from the air spinning device through the airflow passing the spindle.
  • the fibers placed around the spindle tip move helically around the spindle tip and form a so-called fiber sun.
  • the spindle tip is that region of the spindle in which the transferred fibers move. The removal of air beyond this area of the spindle has no direct influence on the movement of the fibers.
  • the number of Umwindefasern is determined by the distance of the spindle tip of a last terminal point of the sliver. The sliver is passed before reaching the fiber guide element by a pair of rollers which forms a terminal point. Due to the length of the individual fibers, the distance between this clamping point and the spindle tip is selected.
  • the drainage channel is designed in its geometric shape such that fibers located at the exit are caught by the wraparound fibers prior to deployment and introduced into the yarn or roving.
  • This has the advantage that the finish is reduced without affecting the turbulence of the Umwindemaschinen.
  • the shape of the discharge channel changes the circulation of the fibers around the spindle tip. Viewed along the length of the fibers, individual sections of the fibers are subject to accelerations, decelerations or swirls in their rotating helical motion due to the design of the bleed channel. The nature of the movements made by the fibers around the spindle tip also affects the yarn twist. By reducing the rotational speed results in a lower rotation, the air and flow conditions in the vortex zone must not be changed, for example by reducing the fluidizing air.
  • the air spinning device comprises a nozzle body and a hollow spindle with a spindle tip and a longitudinal axis, wherein the spindle tip protrudes into the nozzle body and forms an outlet channel with an annular cross-sectional area between an outer surface of the spindle tip and an inner surface of the nozzle body.
  • a gap width seen normal to the longitudinal axis of the spindle at a certain point of the discharge channel is constant over the circumference of the spindle.
  • the outer surface of the spindle tip is shaped such that in the discharge channel in its course in the direction of the longitudinal axis of the spindle at least two bottlenecks are formed, wherein the discharge channel in its course in the direction of the longitudinal axis of the spindle at each of these bottlenecks has an annular cross-sectional area, the smaller is as the annular cross-sectional area of the discharge channel before and after each of these at least two bottlenecks.
  • the inner surface of the nozzle body is cylindrically shaped, so that over the circumference of the spindle at each point of the discharge channel results in the same gap width and an annular cross section is formed.
  • the bottlenecks produce a change in the turbulence the outflowing air.
  • the speed of the outflowing air is influenced by the bottlenecks. The speed is reduced before a constriction, increased by the narrowing of the discharge channel and reduced again by the subsequent expansion of the discharge channel.
  • By creating a tear-off edge due to the shape at the throat backflows or vortices that normally rotate with the air flow along the spindle can be created, which also contributes to the reduction of the outlet.
  • the formation of backflow to a bottleneck is enhanced by a second subsequent bottleneck.
  • the backflow and the resulting vortex cause the fibers, which are normally discharged along the spindle, to be at least partially pressed against the spindle. Near the spindle outer surface, these fibers are caught by the fibers in the fiber sun and incorporated into the yarn.
  • the vortexes created by the backflows rotate about an axis which is substantially perpendicular to the axis of the spindle and is located on a circle concentric with the inner contour of the nozzle body.
  • the vortex turns on the one hand in itself and on the other hand, the vortex is circular, rotated by the fiber sun rotating air flow to the spindle.
  • the formation of a constriction can be effected by providing an annular bead on the outer surface of the spindle tip.
  • the formation of the bead is limited in its geometric form only in that the said cross-sectional area over the circumference of the spindle results in a uniform gap width.

Further, a mechanical connection of the first with the second part of the spindle can be provided, this may for example be a plug or screw connection.
  • the first part of the spindle is formed by the outer surface of the spindle tip, which can be attached to the second part of the spindle, for example in the form of a spindle tip sleeve.
  • the attachment can be done by attaching or another type of attachment, such as screws.
  • a ratio of a maximum outside diameter of the bead to a smallest outside diameter of the spindle tip is preferably 1.05 to 1.5.
  • the spindle tip is formed in a cylindrical shape and the inner surface of the nozzle body is formed such that in the discharge channel in its course in the direction of the longitudinal axis of the spindle at least two bottlenecks are formed, wherein the discharge channel in its course in the direction of the longitudinal axis of the spindle at each of these constrictions has an annular cross-sectional area which is smaller than the annular cross-sectional area of the discharge passage before and after each of these at least two bottlenecks.
  • the constriction can be formed by a bulge in the nozzle body, which projects annularly into the interior of the nozzle body. Also for the execution of such a bulge various geometric shapes are conceivable. The formed bulge may be round or have edges.
