Definitions

  • a plurality of the fiber bundles introduced from the drafting device to the spinning member is discharged from the spinning member as a plurality of the spun yarns, and after united in the doubled-yarn guide, the spun yarn is wound to the winding package as a doubled yarn in the winding part.
  • the yarn producing unit of the spinning member after the back end of the fiber comprising the fiber bundle is reversed by the revolving airflow acted to the tip part of the hollow guide shaft, it is wound around the tip part of the trailing fiber and is sucked into the yarn passage by running the fiber bundle (the spun yarn).
  • the truly twisted-like spun yarn that the twining fiber is existed to the whole of the longitudinal direction is produced respectively in each yarn-producing unit.
  • the switching from the yarn discharging spinning to the normal spinning can be implemented smoothly, only by stopping the operation of the suction-power generating means.
  • the spinning member in the spinning device having the drafting device which drafts the fiber bundle, the spinning member positioned in the downstream side of the drafting device and the winding part which winds the spun yarn produced by the spinning member, the spinning member is comprised by arranging a plurality of the yarn producing units having the hollow guide shaft part and the spinning nozzle part, and the hollow guide shaft part has the hollow guide shaft that the yarn passage extended to the axis direction is formed, and the spinning nozzle part has the air jet nozzle which generates the revolving airflow in the spinning room which is in the tip of the hollow guide shaft, and a plurality of the hollow guide shaft parts and a plurality of the spinning nozzle parts is comprised that they can be freely contacted by the common drive means, and the doubled-yarn guide is provided between the spinning member and the winding part, and the single yarns produced by a plurality of the yarn producing units are united in the doubled-yarn guide, and the yarn is wound to the winding package as the doubled yarn in the winding part.
  • the winding part W it is comprised such that the doubled yarn Y is wound to the package 12 that rotates by being abut against the friction roller 14 while traversed by the traverse guide 15.
  • the yarn Ya, Yb are called the single yarns Ya, Yb, for clearly discriminating two pieces of yarn Ya, Yb produced respectively and the doubled yarn Y formed by uniting these yarn Ya, Yb by two pairs of the yarn producing units.
  • the yarn producing unit U is mainly comprised of a spinning nozzle part N fixed in the after-mentioned first swinging arm and a hollow guide shaft part S which can be united or separated to the spinning nozzle part N.
  • the tip part of the needle holder 18 is inserted into an opening 22' of a housing 22, and the nozzle block 19 positioned in the housing 22 is installed by inserting into an opening 24' formed in a first swinging arm 24 through an intermediate board 23 having an opening 23' that the nozzle block 19 can be freely inserted.
  • 25 is an air reservoir formed in the housing 22 such as to surround the compressed-air introduction hole of the air jet nozzle 21, and the reservoir 25 is communicated to a compressed-air passage 26 and a shell 27 that the compressed-air passage 26 is formed is connected to the compressed-air supply source (not shown in the drawings).
  • a solenoid valve for switching the jet/halt of the compressed air from the nozzle 21 is provided between the air jet nozzle 21 and the compressed air supply source, and the solenoid valve is switched by the switching signal from the after-mentioned control device.
  • the compressed air supplied to the air reservoir 25 through the compressed-air passage 26 and the like is jet from the air jet nozzle 21 to the tip part 29 direction of the after-mentioned hollow guide shaft 28, and the revolving air is generated in the spinning room 20 and the airflow to the spinning room 20 direction is generated in the guide hole 16 of the needle holder 18, and the suction airflow is generated in the vicinity of the fiber bundle introduction hole positioned in the front roller 7 side of the guide hole 16.
  • the fiber bundle 1 coming from the front roller 7 becomes easier to introduce to the guide hole 16 of the needle holder 18.
  • a leg part attachment hole 47 attached by inserting the leg part 42 formed in the shaft installing block 37 is made around two installing holes 46 formed in the installing pedestal part 45.
  • the example that six leg part attachment holes 47 is made in the installing pedestal part 45 is showed.
  • the spinning that is the yarn producing process is implemented in the state that the spinning nozzle part N and the hollow guide shaft part S are in the spinning position respectively, however in this state, the frustum cone part 39 of the shaft installing block 37 is inserted into the inserting hole 53 formed in the first swinging arm 24.
  • the draft roller Before the starting of the spinning device or in generating the yarn breakage, a part of the draft roller is stopped and the compressed air is not jetted from the air jet nozzle 21 and the assistant nozzle 33, so that the air jet nozzle 21 and the assistant nozzle 33 is not in the operating condition.
  • the fiber bundle 1 whose tip is gripped by the third roller 5 in the stopping condition is delivered by the rotating drive of the back roller 4 and the third roller 5, and is supplied to the yarn producing unit U of the spinning member P through the second roller 6 and the front roller 7.
  • the compressed air is jetted from the air jet nozzle 21 and the assistant nozzle 33.
  • the twining spun yarn produced by the yarn discharging spinning is all sucked into the spinning-side yarn end guide member 82 and eliminated, and the truly twisted-like spun yarn (the doubled yarn Y) produced after switching to the normal spinning is pieced to the winding-side yarn end (the doubled yarn Y) in the yarn piecing part 81. Therefore, only the doubled yarn Y that the truly twisted-like spun yarns Ya, Yb produced by the normal spinning are united can be winded in the winding package 12.
  • the spinning member is comprised of arranging a plurality of the yarn producing units having the hollow guide shaft formed in the yarn passage extended to the axis direction and the air jet nozzle generating the revolving airflow in the spinning room in the tip of the hollow guide shaft, and the doubled-yarn guide is equipped between the spinning member and the winding part and the single yarns produced in a plurality of the yarn producing units are united in the doubled-yarn guide, the single yarn produced in the spinning member does not balloon between the spinning member and the doubled-yarn guide, so that, like the conventional spinning device, the trouble like the yarn breakage by ballooning is not generated and the quality of the doubled yarn is not deteriorated.
