Definitions

  • the invention relates to a device for producing a spun yarn from a Stapelfäser notion, with a delivery roller pair having drafting, with a drafting downstream air nozzle assembly containing a vortex chamber with an exhaust duct, and with a suction opening the delivery roller pair associated cleaning channel, wherein the exhaust duct at least is formed in its initial region as a ring channel to a stationary spindle-shaped member, and wherein the cleaning channel is combined with the exhaust duct and both are connected together to a common negative pressure source.
  • a device of this kind is from the DE 103 11 826 A1 State of the art.
  • a staple fiber strand is warped in the drafting to a fiber ribbon, which is then given the spin rotation in the air jet unit.
  • the fiber ribbon is first passed through an inlet channel of the air nozzle assembly in a vortex chamber, which is associated with a fluid means for generating a vortex flow around an inlet opening of a yarn withdrawal channel around.
  • a fluid means for generating a vortex flow around an inlet opening of a yarn withdrawal channel around around.
  • first the front ends of the fibers held in the fiber ribbon are guided in the yarn withdrawal channel, while rear free fiber ends are spread, captured by the turbulent flow and around which are already in the inlet opening of the yarn withdrawal channel, so a bound front ends are rotated around, creating a thread with largely true rotation is generated.
  • Such a device allows high spinning speeds, which, above all, high demands are placed on the drafting unit upstream of the air jet unit.
  • the pair of delivery rollers running particularly fast tends to cause fiber fly on its peripheral surfaces.
  • the delivery roller pair of the known Device associated with a suction port of a cleaning channel, which should ensure a cleanliness of the delivery roller pair.
  • the cleaning channel is associated with the known device of the pressure roller of the pair of delivery rollers and opens inside the air nozzle unit in the exhaust duct.
  • the exhaust duct is formed in the mouth region as an annular channel around a spindle-shaped stationary component. Both channels are connected to a common vacuum channel, which leads to a particularly space-saving design.
  • suction ducts or suction hoses need not be passed through the drafting area by having the pressure rollers with their loading means.
  • suction devices in this area would make the construction and operation of the device extremely complicated.
  • this embodiment has the advantage that, for example, necessary for maintenance changes of the air nozzle unit only a connection nozzle is to be solved by the air jet unit.
  • the known device has the disadvantage that the cleaning channel opens into the annular channel, which leads around the spindle-shaped component in an annular manner.
  • This annular channel serves to summarize the air to be sucked from the vortex chamber and to guide it into the exhaust air duct.
  • the annular channel must therefore surround the spindle-shaped component continuously as a complete circular ring.
  • the stream of air flowing from the cleaning channel into the exhaust air duct with the fibers and dirt particles sucked from the pressure roller is divided into two partial air streams through the central spindle-shaped component when it flows into the annular channel and is guided past the spindle-shaped component on both sides.
  • the present invention is based on the object to improve a device of the type mentioned while maintaining the stated advantages to reduce the tendency to clog and thus increase the reliability and reliability.
  • the object is achieved in that the cleaning channel unifies only in the air flow direction behind the annular channel with the exhaust duct.
  • the cleaning channel also has an annular region which is arranged around the spindle-shaped component.
  • this annular region is not connected to the annular channel and formed in its cross section not as a complete annulus, but only as a section of a circular ring, so that the disadvantageous described division of the air flow is omitted.
  • the air jet unit can be connected by a single connection nozzle with the vacuum source, and it is a simple expandability of the air jet unit guaranteed.
