Definitions

  • ABSTRACT An open end spinning device comprising a spinning rotor having a spinning chamber provided with an internal fiber collecting surface to which fibers in discrete form are fed through a fiber feed passage and from which they are removed to form a twisted yarn which is continuously withdrawn from the spinning chamber through a yarn delivery passage.
  • the rotor has at one end thereof closure means formed with a cylindrical or generally cylindrical penetrating portion which penetrates into the chamber of the spinning rotor in concentric relation to the spinning axis of the rotor and through which the fiber feed passage and the yarn delivery passage pass.
  • the yarn delivery passage passes through the penetrating portion and opens into the end face of the penetrating portion, and the fiber feed passages passes through the penetrating portion and opens into a recess formed in the penetrating portion at such a position that fibers from the end of the fiber feed passage are directed to the fiber collecting surface of the spinning rotor, the recess being so formed as not to extend around the whole of the circumference of the penetrating portion.
  • the present invention relates to open end spinning devices of the kind in which fibers in discrete form are fed to an internal fiber collecting surface of a spinning rotor through a fiber feed duct and continuously removed from the fiber collecting surface to form a twisted yarn which is withdrawn from the spinning rotor through a yarn delivery duct.
  • An open end spinning device of the kind specified has hitherto been proposed in which the spinning rotor is closed at one end and open end at the other end, the open end being closed during normal operation by a closure member through which pass a fiber feed tube and an axially extending yarn delivery tube.
  • the yarn delivery tube is provided with an extended or flared yarn inlet end which projects below the underside of the closure member and it has been found that yarn or fibers tend to wrap around the inlet end, making cleaning of the spinning rotor and closure member difficult following end breakage.
  • an open end spinning device comprising a spinning rotor having a spinning chamber provided with an internal fiber collecting surface to which fibers in discrete form are fed through a fiber feed passage and from which they are removed to form a twisted yarn which leaves the spinning chamber through a yarn delivery passage, the rotor having at one end thereof end closure means formed with a cylindrical or generally cylindrical penetrating portion which penetrates into the chamber of the spinning rotor and through which the fiber feed passage and the yarn delivery passage pass, said yarn delivery passage passing through the penetrating portion and terminating in an open end at the end face of the penetrating portion, and the fiber feed passage including and opening into a recess formed in the penetrating portion at such a position that fibers transported through said passage are directed to the fiber collecting surface of the spinning rotor.
  • FIG. 1 is a sectional side elevation of an open end spinning device according to a first embodiment of the invention
  • FIG. 2 is a section of the device shown in FIG. 1, taken on the line ll-II in FIG. 1 and viewed in the direction indicated in FIG. 1,
  • FIG. 3 is a sectional side elevation of a part of an open end spinning device according to a second embodiment of the invention.
  • FIG. 4 is a sectional side elevation of part of an open end spinning device according to a third embodiment of the invention.
  • the open end spinning device illustrated comprises a spinning rotor 11 fixedly mounted on one end of a shaft 12 rotatably supported within a bearing housing 13.
  • the drive for the spinning rotor 11 is obtained from a driving belt (not shown) which makes frictional contact with a pulley (not shown) mounted on the other end of the shaft 12.
  • the spinning rotor 11 is formed with a spinning chamber 14 having a circumferential fiber collecting groove 15 and is contained in a housing 16 which is closed by a closure member 17 hingedly attached to the housing 16 by a hinge pin 18 carried by an extension of the housing 16.
  • the closure member 17 is formed with a depending cylindrical portion 19 which in the closed position of the closure member 17 extends into the spinning chamber 14 of the spinning rotor 11 and in concentric relation to the axis of the spinning rotor.
  • the cylindrical portion 19 is provided with an axial bore 20 in which is fitted a yarn delivery tube 21, which terminates in the chamber 14 in an end flange 22, one end face of which abuts against the end face of the cylindrical portion 19 the other end face of which is formed with a peripheral wall 23 extending just below the level of the fiber collecting groove 15 of the spinning rotor 11.
  • the closure member 17 is formed with an extension 24 provided with a tapered bore within which is fitted a fiber feed tube 25 which extends to the end face 26 of the cylindrical projection 19 and which opens into a recess 27 formed in the end flange 22 of the yarn delivery tube 21.
  • the rotor housing 16 is formed with an outlet duct 28 which is connected by a tube 29 to a source of suction not shown.
  • the recess 27 cut in the end flange 22 of the delivery tube 21 is in the form of a segment, the bounding chord face of which lies at an angle a to the axis of the suction duct 28. It will be seen that the axis of the fiber feed tube 25 lies in a plane parallel to the plane containing the axis of the suction duct 28 and it has been found that good results are achieved if the angle a is equal to or approximately equal to 19.
  • suction is applied to the interior of the rotor housing 16 by connecting the suction tube 29 to the source of suction, and fibers from a supply (not shown) are drawn through the fiber feed tube 25 in an airstream derived from the suction developed in the housing 16.
  • the fibers pass in discrete form down the tube 25 into the recess 27 from which they are directed on to the wall of the spinning chamber 14 and deposited as a ring of fibers in the fiber collecting groove 15.
  • the fibers in the groove 15 are picked up and formed into a twisted yarn 30 which is continuously withdrawn through the yarn delivery tube 21 and wound on a package (not shown) in conventional manner.
  • the spinning rotor l 1 When it is desired to clear the spinning chamber 14 of fibers contained therein, for example upon an end breakage of yarn, the spinning rotor l 1 is brought to rest whilst maintaining suction conditions within the rotor housing 11. As a result, fibers contained within the spinning chamber 14 are drawn out of the chamber through the open end between the rotor and the cylindrical portion 19 and clearing of the chamber is effected in this way without removing the closure member 17. Because of the generally cylindrical surface provided by the portion 19 and the end flange 22, the fibers in the spinning chamber are unimpeded and readily removed simply by the suction applied to the housing 16. The part of the cylindrical surface of the portion 19 and end flange 22 which is diametrically opposite the suction duct 28 should be smooth and the recess 27 should not therefore extend into that sector of the surface bounded by the angle [3.
  • the recess 27 may be of any desired shape, but is preferably of the shape shown in FIG. 2 with its side face 31 at an angle of approximately 19 to the axis of the fiber feed tube 25 and suction duct 28.
  • the yarn delivery tube 21 is preferably of such a fit within the axial bore 20 that it can be turned to provide for an adjustment of the angle a and a clamping collar 32 is provided for securing the tube in the position to which it has been adjusted.
  • a closure member 171 is provided with a yarn delivery tube 211 which is formed with a shallow end flange 221 and a recess 271 is cut in a depending portion 191 of the closure member 171.
  • the other parts of the device shown in FIG. 3 are as illus trated in FIGS. 1 and 2.
  • a closure member 172 is provided with a yarn delivery tube 212 which has no flange.
  • a projecting portion 192 of the closure member 172 is formed with a recess 272 into which the fiber feed tube 25 opens and a peripheral wall portion 232 is provided on the end face of the portion 192.
  • the other parts of the device shown in FIG. 4 are as illustrated in FIGS. 1 and 2.
  • An open end spinning device comprising a spinning rotor having a spinning chamber provided with an internal fiber col lecting surface to which fibers in discrete form are fed through a fiber feed passage and from which they are removed to form a twisted yarn which is continuously withdrawn from the spinning chamber through a yarn delivery passage, the rotor having at one end thereof closure means formed with a cylindrical or generally cylindrical penetrating portion which penetrates into the chamber of the spinning rotor in concentric relation to the spinning axis of the rotor and through which the fiber feed passage and the yarn delivery passage pass, said yarn delivery passage passing through the penetrating portion and opening into the end face of the penetrating portion, and the fiber feed passage passing through the penetrating portion and opening into a recess formed in the penetrating portion at such a position that fibers from the end of the fiber feed passage are directed to the fiber collecting surface of the spinning rotor, said recess being formed to extend around less than the whole of the circumference of the penetrating portion.
  • a device wherein said recess extends into or through said penetrating portion in a plane at right angles to the axis of the penetrating portion.
  • a device wherein said recess is in the form of a segment of the directrix of said penetrating portion.
  • a device wherein the spinning rotor is housed in a housing to which suction is applied from a suction passage extending away from the housing in a predetermined direction, and wherein said recess is so formed in the penetrating portion as not to interrupt the part of the cylindrical surface of the penetrating portion in a predetermined region remote from the suction passage.
  • a device wherein the axis of the suction passage lies in a plane passing through the rotary axis of the spinning rotor.
  • a device wherein the axis of the fiber feed passage lies in a plane parallel to the said plane containing the axis of the suction passage.
  • chordal face of the recess is inclined at an angle of about 19 to the plane containing the axis of the suction passage.
  • closure means takes the form of a top cover for said housing and is hingedly mounted on a supporting frame.
  • a device wherein the position of the fiber feed passage in relation to the suction passage is such that fibers are transported to said fiber collecting surface in a direction toward the suction passage.
  • a device wherein the end face of the penetrating portion or a part of the end face thereof lies below the level of the fiber collecting surface of the spinning rotor, whereby yarn passing to the yarn delivery passage follows a deflected path.
  • a device wherein the end face of the penetrating portion is formed with a peripheral wall which extends below the level of the fiber collecting surface.
  • said penetrating portion includes a cylindrical extension of a body portion of the closure means and a yarn delivery tube which fits into an axial bore therein and terminates at the end face of the cylindrical extension.
  • a device according to any of claim 14, wherein said yarn delivery tube can be turned about its axis in the body portion of the closure means, thereby to provide for adjustment of the position of the recess in relation to the suction passage and the fiber feed passage.
  • said penetrating portion includes a cylindrical extension of a body portion of the closure means and a yarn delivery tube which passes through an axial bore therein and terminates in a cylindrical or substantially cylindrical end flange which abuts against the end face of the cylindrical extension of the body portion of the closure means.
