  • Each of the spinning units 2 includes a drafting device (a yarn supplying section) 7, an air spinning device (the yarn supplying section) 9, a yarn accumulating device 22, a yarn jointing device 23, a yarn monitoring device 25, and a winding device (a winding section) 26 in this order from upstream to downstream.
  • Each device included in the spinning unit 2 is controlled by a not-shown unit controller arranged in the spinning unit 2.
  • Each device included in the spinning unit 2 is mounted on a frame 31 (see FIG. 2 ). Alternatively, each device included in the spinning unit 2 can be controlled by the machine-frame controlling device.

  • An apron belt 75b and an apron belt 75a are stretched over a top roller and a bottom roller of the middle roller pair 73, respectively.
  • the air spinning device 9 generates the yarn T by applying twists by using a swirling air current to the fiber bundle F drafted by the drafting device 7.
  • the air spinning device 9 includes a spinning chamber, a fiber guiding section, a swirling air current generating nozzle, and a hollow guiding shaft.
  • the fiber guiding section guides the fiber bundle F supplied from the drafting device 7 located upstream to the spinning chamber.
  • the swirling air current generating nozzles are arranged surrounding a traveling path of the fiber bundle F.
  • a swirling air current is generated in the spinning chamber by jetting air from the swirling air current generating nozzles.
  • the fiber ends of the fibers constituting the fiber bundle F are reversed and whirled by this swirling air current.

  • the yarn accumulating device 22 operates such that the yarn T is unwound when the yarn tension on the downstream is increased, and the yarn T is prevented from being unwound when the yarn tension is decreased (when the yarn T is about to have a slack). With this operation, the yarn accumulating device 22 can remove the slack of the yarn T and apply an appropriate tension on the yarn T. Furthermore, because the yarn hooking member 43 operates to absorb a variation of the tension applied on the yarn T between the yarn accumulating device 22 and the winding device 26, the variation of the tension is prevented from affecting the yarn T between the air spinning device 9 and the yarn accumulating device 22.

  • the yarn jointing device 23 joints a yarn T from the air spinning device 9 and a yarn T from the package P when the yarn T becomes discontinuous between the air spinning device 9 and the package P due to some reason.
  • the yarn jointing device 23 is a splicer device that twists and joints the yarn ends by using the swirling air current generated by compressed air.

  • the second catching and guiding device 28, after catching the yarn T from the package P, guides the yarn T from the package P to the yarn jointing device 23 by pivoting downward.
  • the yarn jointing device 23 By driving the yarn jointing device 23 while being in a state in which the yarn T from the air spinning device 9 and the yarn T from the package P have been guided in the yarn jointing device 23, the yarn T from the air spinning device 9 and the yarn T from the package P are jointed, thereby causing the yarn T to be in a continuous state between the air spinning device 9 and the package P. With this action, the winding of the yarn T around the package P can be resumed.
  • the yarn monitoring device 25 monitors a thickness of the traveling yarn T with a not-shown optical transmission type sensor.
  • the yarn monitoring device 25 transmits, upon detecting a yarn defect (a part in which the thickness of the yarn T and the like is abnormal) in the yarn T, a yarn-defect detection signal to the unit controller.
  • the unit controller drives a cutter 24 included in the yarn monitoring device 25, or stops the drafting device 7 to stop the supply of the sliver S, to cut the yarn T.
  • the sensor with which the yarn monitoring device 25 monitors the thickness of the yarn T is not limited to the optical transmission type sensor, and can, for example, be a capacitance type sensor.
  • the yarn monitoring device 25 can monitor a foreign substance contained in the yarn T as the yarn defect. As long as the cutter 24 is arranged between the yarn accumulating device 22 and the winding device 26, the cutter 24 can be arranged separately from the yarn monitoring device 25.
