Definitions

  • the present invention relates to a yarn controlling apparatus, and more particularly to apparatus for automatically guiding a yarn into the nip between a pair of cooperating transporting rollers.
  • the apparatus is particularly advantageously used for transporting rollers disposed between the discharge opening of a spinning chamber and a winding roller which winds the yarn onto a bobbin while oscillating the yarn in axial direction where by a cross wound yarn package is formed.
  • the transporting rollers withdraw the newly spun yarn from the spinning chamber and supply it to the winding roller.
  • One of the transporting rollers is driven and extends across the discharge openings of several spinning chambers, while the second roller is a pressure roller, individually provided for each spinning chamber. It is customary to provide yarn guides between each spinning chamber and the transporting rollers, 'and between the transporting rollers and the winding roller so that the yarn is guided along a straight path from the discharge opening of the spinning chamber through the nip of the transporting rollers.
  • Devices according to the prior art for introducing the yarn into the nip of the transporting rollers are only semi-automatic and require still a manual operation, while consisting of a great number of complicated parts which do not reliably operate. Furthermore, devices of the prior art are not suitable for spinning machines.
  • Another object of the invention is to provide a yarn controlling apparatus for automatically placing a yarn extending between a supply point and a winding roller into the nip of transporting rollers.
  • Another object of the invention is to use the oscillating motion of a yarn being cross wound by a winding roller,
  • Another object of the invention is to provide an auto matic apparatus for placing a yarn which after repair of a yarn breakage extends between the discharge of a spinning machine and a winding roller, automatically in the nip of a pair of transporting rollers which withdraw the yarn from the spinning chamber and supply it to the winding roller.
  • Another object of the invention is to automatically place the yarn not only in the nip of a pair of transporting rollers, but also in a yarn guide.
  • one embodiment of the invention comprises means for supplying a yarn at a supply point, for example the discharge opening of a rotary spinning chamber; winding roller means for winding up the yarn and for moving the yarn along an axially extending surface line between two end points, as is customary for winding rollers forming a cross wound package; and
  • first and second cooperating transporting rollers forming a nip and being located between the winding roller and the supply point.
  • the first roller is disposed so that a yarn extending between the supply point and the surface line of the winding roller, rests on the peripheral surface of the first roller spaced from the nip of the rollers, and oscillates thereon since it is oscillated in axial direction by the winding roller.
  • the first roller has on the peripheral surface thereof, a gripping means, preferably a notch, engaged by the oscillating yarn so that the gripping means of the turning roller moves the yarn into the nip between the transporting rollers which transport the yarn from the supply point to the winding roller.
  • an imaginary tangential plane determined by the surface line of the winding roller, and by the supply point, the discharge opening of the spinning chamber passes through the first roller, which preferably is a pressure roller cooperating with a driven roller.
  • the pressure roller has a cylindrical periphery and an end face forming an annular edge with the cylindrical peripheral face of the roller and provided with a notch which constitutes the gripping means.
  • the yarn When the yarn is located in one of the end positions extending between one end point of the surface line on the winding roller and the discharge opening of the spinning chamber, it crosses the plane of the end face and the annular edge of the pressure roller, so as to be engaged by the notch in the annular edge whereupon the yarn is carried into the nip between the rollers in the region of the annular edge, and during further oscillation moves further in axial direction into the nip, and at the same time into open yarn guides provided between the spinning chamber and the transporting rollers, and between the transporting rollers and the winding roller.
  • the yarn guides are located in a plane which extends between the end face having the notch, and a transverse plane of symmetry of the pressure roller.
  • One marginal tangent line of the imaginary tangential plane on the winding roller passes through the end face of the pressure roller and the other marginal tangent line passes through the cylindrical portion of the pressure roller.
  • the recesses of the open yarn guides are preferably located in a plane passing through the discharge opening of the spinning chamber, and the yarn guide between the transporting rollers and the winding roller, has on one side a guide face leadingto its recess for guiding the oscillating yarn into the recess.
  • An imaginary line between the other thread guide and one of the end points of the surface line on the winding roller passes through the pressure roller in the region between its transverse axis and the gripping notch on its end face.
  • FIG. 1 is a fragmentary schematic side elevation illustrating the winding apparatus of a spinning unit provided with the yarn control apparatus of the invention, in a working position during normal winding operations;
  • FIG. 2 is a fragmentary schematic front view of the apparatus shown in FIG. 1 in the same working position;
  • FIG. 3 is a fragmentary schematic side elevation illustrating the apparatus of FIG. 1 after a yarn breakage, and being partly diagrammatic;
  • FIG. 4 is a fragmentary schematic front view illustrating the apparatus in the same condition as in FIG. 3, and being partly diagrammatic.
  • a spinning machine has a plurality of spinning units, each including a spinning chamber having a discharge opening 1.
  • a driven transporting roller 4 extends along all discharge openings 1, which constitute supply points for yarn, only one discharge opening or supply point 1 being shown in the drawing.
  • the yarn spun in the spinning chamber is discharged at supply point 1, guided in a recess of a front yarn guide 6 into the nip 8 of a pair of transporting rollers including drive roller 4 and pressure roller which rotate in the direction indicated by arrows to withdraw the yarn from the spinning chamber and to transport the yarn P to a winding roller 2 of known construction which rotates to form a cross wound package 3 on a bobbin, and causes during rotation angular oscillation of the yarn P between the end positions P P and between the end points 19 and 20 on an axially extending surface line 12 on winding roller 2.
  • This type of winding apparatus is well known, and not an object of the invention. As best seen in FIG.
  • the spinning unit is provided with a sensing means, not shown, which responds to a yarn breakage to stop the feeding of fibers into the spinning chamber.
  • the spinning operation is stopped by the stop motion of the machine, and the broken end of the yarn is wound by winding roller 2 into the yarn package 3.
  • the operator unwinds a certain length of yarn P from the package 3 and places the free end of this yarn in the proximity of the discharge opening of the spinning chamber. Since the rotating spinning chamber produces suction by outwardly expelling air through small openings, the free yarn end is sucked into the spinning chamber and connected in the same with newly spun yarn so that the breakage is eliminated and winding operations may continue.
  • the yarn extends directly from the discharge opening 1 to any point of surface line 12 on the periphery of winding roller 2.
  • the yarn extending between discharge opening 1 and winding roller 2 is to be automatically placed in the nip 3 between the transporting rollers 4 and 5 so that the winding operations may continue in the position of FIG. 2.
  • the pressure roller 5 is provided with a notch or corresponding gripping means on the circular edge 9 between end face and the cylindrical peripheral surface thereof. Furthermore, and referring to FIGS. 3 and 4, an imaginary plane 11 tangential to winding roller 2, and passing through supply point 1, surface line 12, and end points 19 and intersects the pressure roller 5, as best seen in FIG. 3. The plane of intersection is preferably spaced from the axis of roller 5, three quarters of the radius r of the same.
  • the open yarn guide 6 is located between plane 11 and drive roller 4.
  • a plane perpendicular to the axes of rollers 5 and 4 passes through supply point 1 and the recesses of thread guide 6 and 7, substantially equidistant from the end face 15 and the transverse plane of symmetry 13 of pressure roller 5, as best seen in FIG. 4.
  • the marginal lines 14 and 16 between supply point 1 and end points 19 and 20 may be considered projections of the yarn oscillated by winding roller after a yarn breakage has been repaired, and before the yarn is placed in the nip of the transporting rollers 4 and 5.
  • the marginal line 14 extends across end face 15 of pressure roller 5, so that a yarn in this position will rest on the peripheral portion of pressure roller 5 and across the annular edge 9. Consequently, during rotation of roller 5 the yarn in position 14 will be engaged by notch 10, and at the same time move inwardly about point 1 in axial direction of roller 5 and into notch 10.
  • the yarn is carried around by notch 10 and placed in the nip of the transporting rollers 4, 5.
  • the other marginal line 16 passes through the cylindrical portion of pressure roller 5, so that a repaired yarn, which is not yet in the nip between the rollers, rests on the cylindrical peripheral surface of roller 5.
  • the rear guide 7 has a rounded off guide face 17 leading to the yarn guiding recess.
  • the free yarn end is introduced into the spinning chamber and extends between supply point 1 and any point of surface line 12 on winding roller 2 substantially in plane 11.
  • the yarn oscillates between positions 14 and 16, a yarn portion sliding at first on the peripheral surface of roller 5.
  • the yarn oscillates until it engages the notch 10 substantially in the position 14 which pulls the yarn into the nip between rollers 5 and 4, the yarn continuing its oscillatory angular motion within the nip 8 until it engages the recess of yarn guide 6.
  • Yarn controlling apparatus comprising, in combination, means for supplying a yarn at a supply point; winding roller means for winding up said yarn and for moving said yarn along an axially extending surface line between two end points; and a pair of first and second rotary transporting rollers forming a nip and located between said winding roller means and said supply point, said first roller being disposed so that a yarn extending between said supply point and said surface line rests on the peripheral surface thereof spaced from said nip, and angularly oscillates thereon while moving between said end points, said first roller having on said peripheral surface a gripping means engaged by said oscillating yarn during rotation of said first roller, and moving said yarn into the nip between said first and second rollers so that the same transport said yarn from said supply point to said winding roller means.
  • Yarn controlling apparatus including an open yarn guide located between said winding roller means and said pair of first and second rollers so that said yarn oscillating between said end points engages said open yarn guide whereby said yarn located in said nip between said first and second rollers is prevented from oscillation in said nip and oscillates between said yarn guide and said winding roller.
  • said open yarn guide has a recess for guiding said yarn located substantially in a plane passing through said supply point perpendicularly to said surface line; wherein said end face and said gripping means are located on one side of said plane; and wherein said yarn guide has a guide face on said one side of said plane and leading to said recess for guiding said oscillating yarn into said recess.
  • a spinning means having a discharge opening for supplying a yarn at a supply point; a winding roller for winding up the spun yarn and for moving said yarn along an axially extending surface line between two end points; a pair of first and second rotary transporting rollers located between said winding roller and said supply point and forming a nip, said first roller having a peripheral surface and an end face forming with the same an annular edge formed with a notch; a front yarn guide located between said supply point and said supporting rollers; and a rear yarn guide located between said transporting rollers and said winding roller; said first transporting roller being disposed so that a tangential plane on said winding roller passing through said surface line, said end points, and said supply point, intersects said first roller, and so that a yarn located substantially in said plane and sliding on the peripheral surface of said first roller, crosses in a marginal position extending between said supply point and one of said end points said annular edge and is engaged by said notch during rotation of said
  • said first roller has such a length and is disposed in such a manner that a yarn passing from said supply point substantially in said tangential plane to the other end point of said surface line, does not cross the other end face of said first roller and oscillates on said peripheral surface of said first roller until engaged by said notch.
