Definitions

  • the present invention relates to a drafting device and a spinning machine.
  • Drafting devices that include plural roller pairs that convey a fiber bundle (which can be a sliver) from an upstream side to a downstream side while drafting the fiber bundle, and a regulating member (also called a sliver guide or a condenser) that regulates a width of the fiber bundle between adjacent roller pairs are known in the art (for example, Japanese Patent Application Laid-open No. 2004-218105 ).
  • a distance between adjacent roller pairs needs to be adjusted in accordance with a fiber length of the fibers forming the fiber bundle.
  • a distance from the roller pair on the upstream side to the regulating member increases when the distance between adjacent roller pairs is increased, a width of the fiber bundle at the roller pair on the upstream side increases, leading to a reduction in the drafting resistance.
  • the reduced drafting resistance can make the movement of the fibers uncontrollable and the fibers may unfavorably wind around the roller pair on the upstream side (the so-called wrapping-up phenomenon).
  • the drafting device drafts a fiber bundle, and includes plural roller pairs that convey the fiber bundle from an upstream side to a downstream side while drafting the fiber bundle, the roller pairs include a first roller pair arranged at an extreme upstream side and a second roller pair arranged at an extreme downstream side, a first regulating member that is arranged between the first roller pair and the second roller pair and that regulates a width of the fiber bundle, and a second regulating member that is arranged between the first regulating member and the second roller pair and that regulates the width of the fiber bundle.
  • a spinning machine includes the above drafting device, an air spinning device that twists the fiber bundle drafted by the drafting device to form a spun yarn, and a winding device that winds the spun yarn formed by the air spinning device into a package.
  • a spinning machine 1 includes plural spinning units 2, a yarn joining carrier 3, a blower box 4, and a motor box 5.
  • the spinning units 2 are arranged side-by-side. Each spinning unit 2 forms a spun yarn Y and winds the spun yarn Y to form a package P.
  • the yarn joining carrier 3 performs a yarn joining operation in the spinning unit 2 where breakage of the spun yarn Y has occurred.
  • the blower box 4 houses therein an air supplying source, etc., for generating a suction flow and swirling air current, etc., in each component part of the spinning units 2.
  • the motor box 5 houses therein a motor, etc., for supplying power to each component part of the spinning units 2.
  • upstream side refers to the side where the spun yarn Y is formed and the term “downstream side” refers to the side where the spun yarn Y is wound.
  • front side refers to the side relative to the yarn joining carrier 3 where the yarn path is present, and the term “back side” refers to the opposite side relative to the yarn joining carrier 3.
  • a not shown working passage extending in an arrangement direction of the spinning units 2 is located on the front side of the spinning machine 1. An operator can operate and monitor the spinning units 2 from the working passage.
  • each spinning unit 2 includes, sequentially from the upstream side, a drafting device 6, an air spinning device 7, a yarn clearer 8, a tension sensor 9, a yarn pooling device 50, a waxing device 11, and a winding device 12. These devices are directly or indirectly supported by a machine frame 13 in such a manner that the upstream side is on top in a height direction of the spinning machine 1 (that is, the downstream side is at the bottom in the height direction of the spinning machine 1).
  • the drafting device 6 drafts a sliver (fiber bundle) S.

More specifically (though not shown), the air spinning device 7 includes a spinning chamber, a fiber guiding member, a swirling air current generating nozzle, and a hollow guide shaft member.
  • the fiber guiding member guides the fiber bundle F supplied by the drafting device 6 into the spinning chamber.
  • the swirling airflow generating nozzle is arranged near the route over which the fiber bundle F runs, and create a swirling airflow inside the spinning chamber.
  • the swirling airflow causes the fiber end of the fiber bundle F guided into the spinning chamber to be reversed and swirled.
  • the hollow guide shaft member guides the spun yarn Y from inside the spinning chamber to outside of the air spinning device 7.
  • the yarn clearer 8 monitors the running spun yarn Y at a position between the air spinning device 7 and the yarn pooling device 50.
