  • the spinning device 9 is adapted to apply twists to the fiber bundle 8 fed from the draft device 11 to produce the spun yarn 10. Although a detailed structure of the spinning device 9 is not illustrated, the spinning device 9 of the present embodiment is a pneumatic-type adapted to apply twists to the fiber bundle 8 using whirling airflow.
  • the yarn slack eliminating device 12 is arranged downstream of the spinning device 9.

  • the yarn hooking member 22 and the slack eliminating roller 21 are connected by a resistance applying section (not illustrated) adapted to apply resistance in an appropriate manner such as a magnetic or an electric manner.
  • the resistance applying section applies an appropriate amount of resistance torque that opposes rotation of the yarn hooking member 22 with respect to the slack eliminating roller 21.

  • a stroke (hereinafter may be referred to as a traverse stroke) of the traverse guide 74a of the traverse device 74 is set to form the package 80 having the winding width 80W of 152 millimeters.
  • the entire length 73L of the winding drum 73 is longer than the winding width 80W (152 millimeters).
  • the winding drum 73 includes a drum main body 75 and a high-frictional portion 76.
  • the drum main body 75 is a cylindrical member forming a large portion of the winding drum 73.
  • the entire length 73L of the winding drum 73 corresponds to an entire length of the drum main body 75.
  • the drum main body 75 is fixed to the drive shaft 79. Thus, by driving the drive shaft 79 by an electric motor or the like, for example, the drum main body 75 can be rotationally driven.
  • the high-frictional portion 76 is a ring-shaped member formed of elastically deformable rubber. In the present embodiment, a plurality of (two) high-frictional portions 76 are arranged around an outer periphery of the drum main body 75. A frictional surface 77, which is an outer peripheral surface of the high-frictional portion 76, forms a portion of an outer peripheral surface of the winding drum 73.
  • the frictional surface 77 formed on each of the high-frictional portions 76 is adapted to slightly protrude in a radial direction from an outer peripheral surface of the drum main body 75.
  • the frictional surfaces 77 formed on the high-frictional portions 76 make contact with the bobbin 60 or the package 80 stronger than an outer peripheral surface of a portion of the drum main body 75 where the high-frictional portion 76 is not arranged (there may be a case in which only the frictional surfaces 77 of the high-frictional portions 76 make contact with the bobbin 60 or the package 80 depending on hardness of the package 80, or the like).
  • the high-frictional portions 76 of the winding drum 73 can further stably make contact with the package 80.
  • the frictional surfaces 77 formed on the high-frictional portions 76 are arranged so as to avoid making contact with both ends of the package 80 in a winding width direction. As illustrated in FIG. 3 , the high-frictional portions 76 are respectively arranged on a right side and a left side of the winding drum 73 one by one. A left end of the frictional surface 77 formed on the high-frictional portion 76 on the left side is located at a position closer to a center in the winding width direction than a left end of the package 80. A right end of the frictional surface 77 formed on the high-frictional portion 76 on the right side is located at a position closer to the center in the winding width direction than a right end of the package 80.
  • an axial distance 76L from the left end of the high-frictional portion 76 on the left side of the winding drum 73 in FIG. 3 to the right end of the high-frictional portion 76 on the right side of the winding drum 73 is less than 152 millimeters.
  • the axial distance 76L between a point closest to a left end of the winding drum 73 and a point closest to a right end of the winding drum 73 is less than 152 millimeters.
  • the "winding width" of the package 80 means a winding width at the time of traversing and winding the spun yarn 10 by the winding device 7. That is, in some cases, a middle portion of a yarn layer of the package 80 is deformed to protrude outward due to great winding tension of the spun yarn 10 after the package 80 has been fully wound and doffed, but the "winding width" in the present specification means a winding width not considering such a subsequent deformation.
  • the high-frictional portions 76 are fixed by being fitted into ring-shaped groove portions 78 formed around the outer periphery of the drum main body 75.
  • the groove portions 78 are formed in the same width as the high-frictional portions 76.
  • the groove portions 78 are arranged to correspond to the number and attached positions of the high-frictional portions 76.
  • the high-frictional portions 76 are formed into a cylinder shape having a certain thickness. Inner diameters of the high-frictional portions 76 are formed smaller than an outer diameter of a portion of the drum main body 75, which has become small due to the groove portion 78 being formed.
  • the high-frictional portions 76 formed of rubber are attached to the groove portions 78 while being elastically deformed outward in a radial direction, the high-frictional portions 76 are strongly fixed to the groove portions 78 of the drum main body 75 by restoring force that acts inward in the radial direction. Consequently, without using a fixing means such as an adhesive or the like, the high-frictional portions 76 and the drum main body 75 can be integrally rotated without slipping from each other.
  • the thicknesses of the high-frictional portions 76 are formed slightly larger than depths of the groove portions 78 of the winding drum 73. Accordingly, the frictional surfaces 77 formed on the high-frictional portions 76 attached to the groove portions 78 of the drum main body 75 can be slightly protruded from the outer peripheral surface of the drum main body 75.
  • the high-frictional portions 76 are formed of rubber. Knurling processing is performed on the frictional surfaces 77 formed on the high-frictional portions 76, and a minute concave and a minute recess are formed to increase a friction coefficient. In such a manner, the package 80 can be driven with greatly secured frictional force generated between the high-frictional portions 76 and the package 80. Thus, when driving the package 80 by the high-frictional portions 76, even a heavy nearly fully-wound package 80 can be promptly shifted from a stop state to a high-speed rotation state.
  • productivity of the package 80 can be advantageously improved.
  • the fine spinning machine 1 of the present embodiment interrupts winding upon detection of a yarn defect by the yarn quality measuring device 52 and restarts the winding after the yarn defect has been removed and yarn joining operation has been performed, stop and restart of winding in the winding device 7 may be frequently repeated.
  • prompt shift from a rotation stop state to a normal rotational speed is essential to improve productivity.
  • the straight winding means that the spun yarn 10 is not traversed and is wound around a same portion. That is, when the spun yarn 10 is started being wound around an empty bobbin 60 or when interrupted winding is restarted, first, rotation of the bobbin 60 or the package 80 is started under a state in which the spun yarn 10 is not hooked on the traverse guide 74a, and the spun yarn 10 is wound without being traversed (for example, around a position close to the center in the winding width of the package 80).
  • traverse of the spun yarn 10 is started.
  • a reason for delaying start of the traverse of the spun yarn 10 is that since tension of the spun yarn 10 is unstable under a state where the rotational speed of the bobbin 60 or the package 80 is insufficient, the spun yarn 10 may not be engaged with the traverse guide 74a or winding cannot be performed due to the spun yarn 10 being entangled with the traverse guide 74a.
  • the straight winding is formed while the rotational speed of the bobbin 60 or the package 80 has not reached the normal rotational speed, but the straight winding decreases quality of the package 80.
  • the winding drum 73 of the present embodiment includes the high-frictional portions 76, the bobbin 60 or the package 80 can be promptly shifted from the rotation stop state to a normal rotational state. Consequently, the package 80 having less straight winding and high quality can be produced.
  • the traverse guide 74a is driven and reciprocated within a predetermined traverse stroke 74W illustrated in FIG. 4 .
  • the winding device 7 winds the spun yarn 10 around the outer peripheral surface of the rotating package 80 while traversing the spun yarn 10.
  • the traverse stroke 74W of the traverse guide 74a includes and is larger than a width from an outermost end on one side to an outermost end on another side in an axial direction in which the high-frictional portions 76 (the frictional surfaces 77) of the winding drum 73 are arranged. If description is made with reference to a direction in FIG.
  • an end on a left side of the traverse stroke 74W of the traverse guide 74a is located further to the left of the left end of the high-frictional portion 76 on the left side of the winding drum 73, and an end on a right side of the traverse stroke 74W is located further to the right of the right end of the high-frictional portion 76 on the right side.
  • the traverse stroke 74W of the traverse guide 74a includes and is larger than an entire width (a length corresponding to the axial distance 76L in FIG. 3 ) of the frictional surfaces 77 formed on the plurality of high-frictional portions 76. Accordingly, the spun yarn 10 can be wound around the package 80 while being traversed so as to pass over contact portions of the high-frictional portions 76 of the winding drum 73 and the package 80.
  • the spun yarn 10 is wound in a zig-zag manner while being turned at both ends of the winding width of the package 80 by being traversed by the traverse guide 74a.
  • a yarn is turned while receiving strong friction or restriction between the frictional driving section and the package.
  • a traverse width of the traverse guide 74a is formed to be larger than a width of a region where the high-frictional portions 76 of the winding drum 73 are arranged.
  • the high-frictional portions 76 of the winding drum 73 are arranged in relation to the traverse stroke 74W of the traverse guide 74a such that the high-frictional portions 76 do not make contact with both ends of the package 80.
  • the spun yarn 10 around the turning point can be prevented from making contact with the high-frictional portions 76 of the winding drum 73, even if irregular force is applied to the spun yarn 10, the force can be easily deflected by the spun yarn 10 being deformed or the like as required. Consequently, a yarn breakage of the spun yarn 10 around the ends of the traverse stroke 74W can be effectively prevented.
  • Tendency of hardness of the package 80 in an axial direction thereof will be described.
  • tension of the spun yarn 10 when the traverse guide 74a is located at an end of the traverse stroke 74W is greater than when the traverse guide 74a is located at a center thereof since a yarn path of the spun yarn 10 is longer.
  • density of the spun yarn 10 is high since the spun yarn 10 is turned. Accordingly, the package 80 is harder at the both ends in the axial direction than the center.
  • the high-frictional portions 76 are arranged to make contact with not both ends of the package 80, but positions slightly close to the center. Since the fine spinning machine 1 of the present embodiment is provided with the yarn slack eliminating device 12, variation in tension of the spun yarn 10 between a center and ends of the traverse stroke 74W can be favorably reduced by the yarn slack eliminating device 12. Consequently, difference in hardness that occurs between the center and both ends of the winding width of the package 80 can be reduced. Thus, even when the high-frictional portions 76 are made into contact with not both ends of the package 80, but the portions slightly close to the center and are driven, favorable drive force can be obtained.
  • FIG. 5 illustration of the traverse guide 74a is omitted for convenience of description.
  • the same reference numerals are denoted on the same members as or similar members with the above-described embodiment, and description may be omitted.
  • the high-frictional portion 76 may be further provided to a substantially central position in the winding width (the traverse stroke 74W) of the package 80.
  • the high-frictional portion 76 at the central position is arranged at a position that bisects the axial length of the winding drum 73.
  • a yarn breakage of the spun yarn 10 around the ends of the traverse stroke 74W can be prevented.
  • the high-frictional portions 76 are arranged so as to avoid a position around the central position (a position where straight winding is performed) in the winding width of the package 80. Accordingly, since straight winding is stably performed, quality of the package 80 can be improved.

  • a surface shape and a material of the frictional surfaces 77 differ from the drum main body 75 such that the frictional surfaces 77 have a frictional force higher than other portion (the outer peripheral surface of the drum main body 75).
  • Both of the high-frictional portions 76 are arranged such that the frictional surfaces 77 make contact with inner portions of the package 80 located inward with respect to ends of the package 80.
  • a heavy package 80 can be promptly shifted from the stop state to the high-speed rotation state by being strongly driven with the high-frictional portions 76. Furthermore, since the frictional surfaces 77 formed on the high-frictional portions 76 are arranged to make contact with the inner portions of the package 80 located inward with respect to the ends of the package 80, even if irregular force is applied to the spun yarn 10 when the spun yarn 10 is wound around either end of the package 80, the force can be easily released. Consequently, a yarn breakage can be effectively prevented from occurring at both ends of the package 80.
  • the axial distance 76L between the point closest to one end of the winding drum 73 and the point closest to another end of the winding drum 73 is less than 152 millimeters. 152 millimeters is one example of the winding width 80W of the package 80.

  • the frictional surfaces 77 formed on the high-frictional portions 76 can be prevented from making contact with a straight winding portion that is frequently formed around the center of the package 80 in the axial direction thereof (the straight winding portion generally makes contact with the center of the winding drum 73 in its axial direction), and thus the outer peripheral surface of the package 80 can be prevented from being disarranged.
  • the high-frictional portions 76 are formed of rubber.
  • the package 80 can be strongly driven and rotated with a low-cost configuration.
  • a concave and a recess are formed on the frictional surfaces 77 formed on the high-frictional portions 76.

  • the traverse guide 74a traverses the spun yarn 10 within a stroke including and larger than the entire width of the frictional surfaces 77 formed on the (plurality of) high-frictional portions 76.
  • the winding device 7 of the present embodiment includes two bobbin holders 72 and the cradle 71.
  • the bobbin holders 72 rotatably hold the ends of the bobbin 60 for a cheese package.

  • the high-frictional portions 76 of the winding drum 73 are arranged so as to avoid the position where the spun yarn 10 is wound without being traversed by the traverse guide 74a immediately after start of rotation of the winding drum 73.
  • the high-frictional portions 76 can be prevented from making contact with a straight winding portion and disarranging a yarn layer, improvement in quality of the package 80 can be realized.
  • the fine spinning machine 1 of the present embodiment includes the spinning device 9, the splicer 43, the suction pipe 44, and the suction mouth 46.
  • the suction pipe 44 catches the spun yarn 10 from the spinning device 9 and guides the caught spun yarn 10 to the splicer 43.

  • a width of the high-frictional portion 76x is formed larger than the high-frictional portion 76 of the winding drum 73 illustrated in FIG. 4 to strongly drive the package 80. Accordingly, the winding drum 73y that can prevent a yarn breakage from occurring at both ends of the package 80 with a small number of components can be provided.

  • the first drum body 81 is formed into a cylindrical shape with a material such as resin and the like, and is arranged to be sandwiched between the high-frictional portions 76y. Both ends of the first drum body 81 in the axial direction are formed into a saw-teeth shape to correspond to the saw-teeth-shaped portions of the high-frictional portions 76y.
  • the second drum bodies 82 are formed into a cylindrical shape with the same material as the first drum body 81 and are respectively arranged at positions corresponding to ends of the winding drum 73z. Ends on inner sides of the second drum bodies 82 in the axial direction are formed into a saw-teeth shape to correspond to the saw-teeth-shaped portions of the high-frictional portions 76y.
  • the second drum body 82, the high-frictional portion 76y, the first drum body 81, the high-frictional portion 76y, and the second drum body 82 are arranged in this order from one end in the axial direction.
  • every member is coupled in a relatively unrotatable manner. In such a manner, the winding drum 73z is formed.
  • the winding drum 73z of the present alternative embodiment is advantageous in terms of a feature in which the spun yarn 10 is unlikely to enter into grooves formed in border portions since the border portions between the high-frictional portions 76y and other portions are a zigzag shape.
  • a change in the winding width of the package 80 can be easily handled by preparing a plurality of first drum bodies 81 having different lengths and by replacing them as necessary.

  • the material of the high-frictional portions 76, 76x, 76y may be same as a material of another portion of a winding drum (for example, the drum main body 75, the first drum body 81, or the second drum body 82).
  • a frictional force of the frictional surface 77 may be increased with respect to other portion, for example, by increasing the frictional coefficient of the frictional surface 77 with unevenness treatment such as knurling processing or the like that forms a concave and a recess on the frictional surface 77.
  • the knurling processing does not necessarily need to be performed on the frictional surface 77 in particular.
  • the same knurling processing may be performed on both of the frictional surface 77 and other portion (for example, each outer peripheral surface of the drum main body 75, the first drum body 81, or the second drum body 82).
  • a frictional force of the high-frictional portion 76 can be increased with respect to the other portion by respectively forming the drum main body 75 and the high-frictional portion 76 with resin and rubber.
  • a method for fixing the high-frictional portions 76, 76x, 76y is not limited to using the groove portion 78 or a sew-teeth-shaped portion, and an adhesive and/or a screw, for example, may be used.
  • the present invention is not limited to so-called 6-inch winding, and may be applied to a winding drum for 3-inch winding or 4-inch winding, or a winding drum to form a package having a large winding width exceeding 6-inch winding.
  • application of the present invention is not precluded even to a winding drum and a winding device to form a package wound with a traverse width other than 152 millimeters.
  • a high-frictional portion may be arranged such that a frictional surface formed on the high-frictional portion makes contact with an inner portion of a package located inward with respect to an end of the package or an entire width of the frictional surface is within a stroke of a traverse guide.
  • the traverse device 74 described in the above-described embodiment reciprocates the traverse guide 74a at a position where a certain degree of gap is formed with respect to both of the outer peripheral surface of the winding drum 73 and the outer peripheral surface of the package 80 to avoid colliding with a component and the like in proximity.
  • a distance between a position where the spun yarn 10 is engaged with the traverse guide 74a and a position where the spun yarn 10 makes contact with the outer peripheral surface of the winding drum 73 or the package 80 cannot be zero.
  • the distance is referred to as a free length. When the free length is long, a space where traverse by the traverse guide 74a is absorbed by deformation of the spun yarn 10 is increased.
  • a winding width of the package 80 formed when the free length is long is smaller than a winding width of the package 80 formed when the free length is short. Due to such a condition of the free length, even when the traverse stroke is set to 152 millimeters or more, the winding width of the package 80 may be narrower than 152 millimeters.
  • the high-frictional portion 76 (76x, 76y) may be arranged such that the frictional surface 77 makes contact with a further inner portion of the package 80 with respect to the winding width narrower than 152 millimeters.
  • the winding width of the package 80 is not necessarily constant from start of winding of the spun yarn 10 around the bobbin 60 until the package 80 becomes nearly fully-wound.
  • the package 80 under an initial state in which the spun yarn 10 is started being wound around the bobbin 60, the package 80 is hard due to a thin yarn layer, but when the winding proceeds and the yarn layer becomes thick, the package 80 may become soft. Then, a point where the winding drum 73 and the package 80 substantially make contact with each other is gradually moved upstream or downstream as winding proceeds, and the free length may be varied accompanying the movement and influence the winding width. In this manner, the winding width of the package 80 may be varied depending on a situation from start of winding until a fully-wound package is obtained.
  • the high-frictional portion 76 (76x, 76y) is preferably arranged to make contact with an inner portion of the package 80 located inward with respect to a width of the package 80 of when the winding width of the package 80 is narrowest.
  • the spun yarn 10 is drawn from the spinning device 9 by the yarn slack eliminating device 12.
  • the spun yarn 10 may be drawn by a delivery roller and a nip roller arranged downstream of the spinning device 9, and the drawn spun yarn 10 may be accumulated by the yarn slack eliminating device 12 located downstream.
  • a winding drum and a winding device of the present invention are not limited to a spinning machine such as a fine spinning machine or the like, and may be widely applied, for example, to a yarn winding machine such as an automatic winder provided with a yarn supplying device in which a yarn supplying bobbin with a yarn wound therearound can be set.
