Definitions

  • the present invention relates to a yarn winding machine that winds yarn around a winding tube while traversing the yarn.
  • a yarn winding machine including a yarn traverse device that traverses yarn.
  • Japanese Unexamined Patent Publication No. 2006-298499 or Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2002-518276 disclose a yarn traverse device including a yarn guide that guides the yarn while engaging the yarn, a traverse arm on which the yarn guide is attached to a tip end thereof, and a driving device that reciprocates the traverse arm.
  • the driving device reciprocates (swings) the traverse arm, which allows the yarn to be wound into a package while being traversed by the yarn guide.
  • a yarn winding machine including a yarn joining device and a yarn guiding member for guiding the yarn to the yarn joining device.
  • the yarn joining device connects a yarn end from a yarn supplying bobbin and a yarn end from a package when the yarn is cut due to detection of a yarn defect or when the yarn breaks while being unwound.
  • the configuration of Japanese Unexamined Patent Application Publication (Translation of PCT Application) No. 2002-518276 has a finger shape in which a tip end of a guide slit (yarn guide section) is opened. Therefore, when a pointer (traverse arm) is reciprocated in an arc shape, the yarn may be released from the guide slit at turns of the pointer. The yarn may be disengaged from the guide slit not only at turns of the pointer but also due to a vibration generated during the traverse operation of the yarn.
  • EP2105398 shows a bobbin winder with a traverse device.
  • a package driving motor rotationally drives a winding bobbin around which a yarn is wound.
  • a traverse guide traverses the yarn.
  • the traverse guide is reciprocatingly driven by a traverse guide driving motor.
  • a reference position serving as a reference for the reciprocating driving is determined by a reference position determining section and stored in a reference position storage section.
  • a motor control section controls the traverse guide driving motor by continuously applying, from beginning to end of winding, the reference position determined by the reference position calcufating section and stored in the reference position storage section before the yarn starts to be wound into the package.
  • the yarn path between a yarn supplying section and the winding bobbin is bent by an arcade guide before it is traversed by the traverse guide.
  • JP 2006 6298499 A shows a further bobbin winder with a traverse device.
  • the bobbin winder comprises a yarn supplying section adapted to supply yarn to be wound into a package; a winding tube supporting section adapted to rotatably support a winding tube around which the yarn is wound to form the package; a traverse arm arranged to traverse the yarn, the traverse arm having a yarn guide section for guiding the yarn, the yarn guide section being arranged at a tip end of the traverse arm; and a traverse driving section adapted to rotationally drive the traverse arm.
  • the bobbin winder further comprises a yarn joining device that connects a yarn end from the package and a yarn end from the yarn supplying section; and a yarn guiding member adapted to catch the yarn end from the package and guide such yarn end.
  • An object of the present invention is to provide a yarn winding machine in which quality degradation can be prevented in end portions of a package while yarn can quickly be guided to a yarn guide section. This object is achieved by a yarn winding machine according to claim 1.
  • a yarn winding machine includes a winding tube supporting section, a contact roller, a traverse arm, and a traverse driving section.
  • the winding tube supporting section is adapted to rotatably support a winding tube around which the yarn is wound to form the package.
  • the contact roller rotates while making contact with the winding tube or the package.
  • the traverse arm traverses the yarn.
  • a yarn guide section for guiding the yarn is arranged at a tip end of the traverse arm.
  • the traverse driving section is adapted to rotationally drive the traverse arm.
  • the yarn guide section includes a regulating section that regulates the yarn at a tip end of the yarn guide section and a guide opening that is formed facing towards a base end of the traverse arm so as to guide the yarn to the regulating section.
  • a rotational axis line of the traverse arm and a yarn path line which is formed by extending a yarn path near the yarn guide section at a traverse end, intersect while forming an acute angle or are parallel to one another.
  • the yarn winding machine comprises a traverse fulcrum of the yarn to be wound into the package, wherein the yarn path line forms a straight line, that connects a point and the traverse fulcrum, provided that the point is a position located most upstream in the yarn making contact with the contact roller.
  • an angle formed by the rotational axis line of the traverse arm and the yarn path line is small or the rotational axis line and the yarn path line are parallel to one another. Accordingly, even if the traverse arm swings to the traverse end, the yarn guide section hardly moves in the direction along the yarn path. Particularly, at the traverse end, the yarn bending caused by the yarn guide section can be reduced to prevent the degradation of the package quality. Since the regulating section is formed in the yarn guide section, the yarn can be prevented from being disengaged from the yarn guide section even if the yarn is pulled by a vibration or an inertial force during the traverse. Moreover, since the yarn is easily guided to the yarn guide section at the beginning of the traverse operation of the traverse arm, the traverse of the yarn can promptly be started by the traverse arm and productivity of the yarn winding machine can be improved.
  • a slope adapted to guide the yarn to the guide opening is preferably formed in the yarn guide section. Therefore, the yarn is reliably and quickly guided to the yarn guide section, and the productivity of the yarn winding machine can be improved.
  • the rotational axis line and the yarn path line are preferably substantially parallel to one another. Therefore, bending of the yarn at the traverse ends caused by the yarn guide section can be suppressed to minimum level, and.a high-quality package can be formed.
  • the yarn guide section when viewed from the axial direction of the contact roller, a position of the yarn guide section at the traverse ends is located more downstream in the yarn path than an intersecting point formed by a perpendicular line, which is drawn from a base end portion of the traverse arm to the yarn path line, and the yarn path line. Therefore, the yarn guide section is brought close to a contact line of the package and the contact roller by setting the traverse arm to an appropriate length, and a free length and a print length can be shortened. As a result, a behavior of the yarn wound into the package can be stabilized to improve the package quality.
  • the "free length" means a distance between the yarn guide section and a point where the yarn makes contact with a surface of the contact roller.
  • the yarn corresponding to the free length is not regulated by the contact roller or the like.
  • the free length is lengthened, the behavior of the yarn traversed at high speed by the yarn guide section becomes unstable and is hardly wound into a satisfactory package.
  • the yarn that is wound into the package while being traversed by the yarn guide section is wound after being once brought into contact with (printed on) the contact roller.
  • the "print length” means a length of a portion in which the yarn wound into the package is in contact with the contact roller.
  • a perpendicular surface is a surface near the yarn supplying section that is perpendicular to a straight line drawn in a direction in which the yarn is unwound from the yarn supplying section
  • the traverse arm is supported by the traverse driving section such that a longitudinal direction of the traverse arm is parallel to the perpendicular surface. Therefore, when the layout of the present invention (the angle formed by the rotational axis line of the traverse arm and the yarn path line is small or the rotational axis line and the yarn path line are parallel to one another) is adopted, and when the traverse arm is perpendicular to the rotational axis line, a layout can be implemented in which the yarn from the yarn supplying section to the package is not bent so much.
  • a perpendicular surface is a surface near the yarn supplying section that is perpendicular to a straight line drawn in a direction in which the yarn is unwound from the yarn supplying section
  • the traverse arm is supported by the traverse driving section such that the yarn guide section is located farther away from the perpendicular surface than the base end portion of the traverse arm. Accordingly, when a yarn traveling pathway from the yarn supplying section to the package is formed in a substantially straight line, the traverse arm is arranged such that the yarn guide section comes close to the contact line of the package and the contact roller. As a result, the free length and the print length can be shortened. Accordingly, the behavior of the yarn wound into the package can be stabilized, and the package quality can be improved.
  • the traverse arm preferably has a bent portion that is bent in a direction towards the contact roller. Therefore, by setting the traverse arm located on the tip end side than the bent portion to an appropriate length, the yarn guide section is brought close to the contact line of the package and the contact roller. Accordingly, the free length and the print length can be shortened. As a result, the behavior of the yarn wound into the package can be stabilized, and the package quality can be improved.
  • the above yarn winding machine preferably includes a rotational driving section adapted to directly drive and rotate the winding tube. Accordingly, a diameter of the contact roller can be reduced compared with the configuration in which the package is driven. Therefore, since the free length and the print length are shortened, the behavior of the wound yarn can be stabilized and the package quality can be improved.
  • the above yarn winding machine includes the yarn supplying section, a yarn joining device, and a yarn guiding member.
  • the yarn supplying section is adapted to supply the yarn wound into the package.
  • the yarn joining device connects a yarn end from the package and a yarn end from the yarn supplying section.
  • the yarn guiding member is adapted to catch the yarn end from the package and can guide the yarn end by the suction opening portion.
  • the traverse arm is supported by the traverse driving section such that at a position where the suction opening portion sucks and catches the yarn end from the package, the yarn guide section is located more upstream in the yarn path than the suction opening portion.
  • the yarn guide section and the yarn guiding member can reliably be prevented from being damaged due to the contact between the traverse arm and the yarn guiding member.
  • the yarn guiding member sucks, catches, and guides the yarn end from the package. At this time, it is not necessary to move the traverse arm to a special retreat position, so that the suspended winding operation of the yarn can quickly be resumed.
  • the above yarn winding machine includes a yarn supplying section
  • the yarn supplying section supplies yarn to be wound into a package.
  • a line along a longitudinal direction of the traverse arm is substantially perpendicular to a straight line that connects a most upstream position of the yarn on the contact roller and the traverse fulcrum.
  • the yarn wound into the package can be prevented from being greatly bent by the yarn guide section. Therefore, the yarn can be wound into the package with little damage while being prevented from being disengaged from the yarn guide section.
  • the traverse driving section supports a rotational shaft of the traverse arm and rotationally drives the traverse arm.
  • the traverse arm is supported by the traverse driving section such that the yarn guide section is located in proximity of a position where the yarn first contacts with the contact roller. Therefore, the free length and the print length are shortened, and the behavior of the yarn wound into the package can be stabilized. As a result, the package quality can be improved while preventing stitching and/or a wrinkle from being generated.
  • the traverse arm preferably includes a bent portion that is bent in a direction towards the contact roller. Therefore, the free length and the print length are further shortened, and the behavior of the yarn wound into the package can further be stabilized. As a result, the package quality can be improved while preventing stitching and/or wrinkle from being generated.

  • the machine setting device 90 mainly includes a setting section 91 and a display section 92.

  • the traverse arm 74 is located at a traverse end portion.
  • a yarn guide section 73 is formed at a tip end of the traverse arm 74.
  • the traverse arm 74 can retain (guide) the yarn 20 by the yarn guide section 73.
  • the yarn guide section 73 reciprocates while retaining the yarn 20, thereby traversing the yarn 20.
  • a reference numeral L1 denotes a rotational axis line of the traverse driving motor 76 (a rotational axis line of the traverse arm 74), and a reference numeral L2 denotes a virtual line straightly drawn from the base end portion of the traverse arm 74 to a longitudinal direction in a side surface of the traverse arm 74 (a center line in a side face of the traverse arm 74).
  • the yarn guide section 73 reciprocates while drawing an arc locus in a virtual plane perpendicular to the rotational axis line L1 of the traverse arm 74 (hereinafter the virtual plane is referred to as "swing plane").
  • the traverse arm 74 is arranged substantially perpendicular to the rotational axis line L1. Therefore, the virtual line L2 is perpendicular to the rotational axis line L1. Accordingly, it can be said that the traverse arm 74 reciprocates in the swing plane.
  • a yarn path line L3 is a straight line indicating the yarn path near the tip end of the traverse arm 74 (the yarn path from an edge of the guide plate 28 to the contact roller 29).
  • the yarn path line L3 is parallel to the rotational axis line L1 of the traverse arm 74. In other words, the yarn path line L3 is perpendicular to the swing plane (and the virtual line L2).
  • the yarn path line L3 may be expressed as "a straight line that connects a point P1 and the traverse fulcrum 27, provided that the point P1 is a position located most upstream in the yarn 20 making contact with the contact roller 29".
  • the point P1 may also be expressed as "a point indicating a position where the yarn 20 guided by the yarn guide section 73 first contacts with the contact roller 29".
  • the yarn guide section 73 reciprocates so as to draw the arc locus about the rotational axis line L1, thereby traversing the yarn 20.
  • a force is applied to the yarn 20 only in a direction parallel to the swing plane. That is, the bending of the yarn path can be reduced because a force that pulls or relaxes the yarn 20 in the direction of the yarn path line L3 (direction along the yarn path) is not applied during the traverse.
  • the bending of the yarn path at the traverse ends can be minimized because the traverse arm 74 is arranged such that a yarn guide point of the yarn guide section 73 is located on the yarn path line L3 at the traverse ends.
  • a force in a direction along the yarn path line L3 is also applied to the yarn 20 during the traverse in addition to the force in the direction within the swing plane. Therefore, the bending of the yarn path is increased than that of the present embodiment.
  • a winding tension of the yarn 20 wound into the package 30 may be increased, hardness of the package 30 may be increased particularly in the end portions of the package, or stitching may be generated. As a result, the package quality is degraded.
  • the traverse arm 74 includes a bent portion 72a that is bent in a direction towards the contact roller 29. Although the bent portion 72a is steeply bent (folded), the bent portion 72a may also be smoothly bent (curved).
  • the yarn guide section 73 is brought close to a contact line of the package 30 and the contact roller 29, so that the free length (a length of the yarn 20 from the traverse arm 74 to a position where the yarn 20 contacts with the contact roller 29) and the print length (a length of the yarn 20 that is in contact with the contact roller 29) can be shortened. Therefore, the behavior of the wound yarn 20 can be stabilized, and the quality of the package 30 can be improved.
  • the peripheral speed of the cylindrical (columnar) contact roller 29 greatly differs from the peripheral speed of the conical winding bobbin 22 (package 30) from the beginning of the winding of the package 30 until yarn layer becomes thick.
  • the winding tension is increased on the large diameter side while the winding tension is decreased on the small diameter side with respect to a central portion in the winding width direction of the package 30. Therefore, stitching or wrinkle is easily generated in the end portions of the package 30, and a defective package may be formed.
  • the traverse arm 74 including the bent portion 72a traverses the yarn 20. Therefore, the bending of the yarn 20 can be reduced while the free length and the print length of the yarn 20 are shortened at the package ends (traverse ends), and the formation of the defective package as described above can be prevented.
  • FIG. 3 illustrates the position of the upper yarn catching member 26 in catching the yarn end.
  • a tip end portion (yarn guide section 73) of the traverse arm 74 is arranged near the contact roller 29 (below and in front of the contact roller 29). This is for shortening the free length and the print length. By shortening the free length and the print length, the behavior of the yarn 20 is stabilized during the winding, thereby improving the quality of the package 30.
  • the traverse arm 74 is provided such that the yarn guide section 73 is arranged on the yarn path line L3 and such that an arm section 72 is arranged at a position where the arm section 72 is retreated from the yarn path line L3.
  • the yarn guide section 73 is provided on the front side of the winder unit 10, and the arm section 72 is provided on the back side of the winder unit 10. Therefore, the traverse arm 74 during the traverse and the upper yarn catching member 26 during the catching of the yarn end do not interfere with one another. As a result, collision of the traverse arm 74 with the upper yarn catching member 26 can reliably be prevented. Therefore, the upper yarn catching member 26 can be swung to the vicinity of the package 30 immediately after the yarn breakage or the yarn cut, so that the yarn joining operation can quickly be performed to promptly resume the winding operation of the package 30.
  • the yarn guide section 73 of the traverse arm 74 will be described below with reference to FIG. 4 .
  • the traverse arm 74 includes the yarn guide section 73 arranged on the tip end and the arm section 72 arranged at the base end.
  • the yarn guide section 73 made of ceramics and aluminum or the like is formed in a hook shape, and the yarn guide section 73 is connected to the tip end of the arm section 72. As illustrated in FIG. 4 , the yarn guide section 73 is formed in a shape curved onto one side. A long and thin yarn hooking groove 71 is formed on an inner circumferential side of the yarn guide section 73 in order to hook the yarn 20. The yarn hooking groove 71 is formed along the longitudinal direction of the traverse arm 74 so as to be extended straight onto the tip end while an opened section (guide opening) 71b is formed in a side portion on one side of the yarn guide section 73.
  • a terminal section (regulating section) 71a of the yarn hooking groove 71 is closed (the tip end of the traverse arm 74 is not opened).
  • the end portion on the opened side (the opened section 71b) of the yarn hooking groove 71 is located closer to the base end of the traverse arm 74 than the terminated end portion (the terminal section 71a).
  • the yarn guide section 73 traverses the yarn 20 while guiding the yarn 20, and when the yarn 20 is wound into the package 30, the yarn 20 is located in the yarn hooking groove 71.
  • An inner wall surface of the yarn hooking groove 71 pushes the yarn 20 accompanying the reciprocation of the yarn guide section 73, whereby the yarn 20 is traversed with respect to the package 30.
  • the opened section 71b of the yarn hooking groove 71 is oriented not towards the tip end of the traverse arm 74 but towards the base end. Therefore, the yarn 20 is not disengaged from the yarn guide section 73 even if a force towards the tip end of the traverse arm 74 is applied to the yarn 20.
  • Two slopes 73a and 73b are formed on a side portion of the yarn guide section 73.
  • the slope 73a is obliquely extended towards the opened section 71b of the yarn hooking groove 71 from the curved tip end portion of the yarn guide section 73.
  • the slope 73b is obliquely extended towards the vicinity of the opened section 71b from the base end portion of the yarn guide section 73 (portion connected to the arm section 72).
  • the yarn 20 makes contact with the slopes 73a and 73b and the yarn 20 can be guided into the yarn hooking groove 71 from the opened section 71b by guide action of the slopes 73a and 73b.
  • the automatic winder 1 of the present embodiment includes the cradle 23, the contact roller 29, the traverse arm 74, and the traverse driving motor 76.
  • the cradle 23 rotatably supports the winding bobbin 22 around which the yarn 20 is wound in order to form the package 30.
  • the contact roller 29 rotates while making contact with the winding bobbin 22 or the package 30.
  • the traverse arm 74 traverses the yarn 20.
  • the yarn guide section 73 is arranged on the tip end of the traverse arm 74 in order to guide the yarn 20.
  • the traverse driving motor 76 rotationally drives the traverse arm 74.
  • the yarn guide section 73 includes the terminal section 71a and the opened section 71b.
  • the terminal section 71a regulates the yarn 20 on the tip end of the yarn guide section 73.
  • the opened section 71b is opened to the base end of the traverse arm 74 so as to guide the yarn 20 to the terminal section 71a.
  • the rotational axis line L1 of the traverse arm 74 is parallel to the yarn path line L3 indicating the yarn path near the yarn guide section 73 at the traverse end.
  • the yarn guide section 73 Since the rotational axis line L1 and the yarn path line L3 are parallel to one another, the yarn guide section 73 hardly moves in the direction along the yarn path line L3 even if the traverse arm 74 swings to the end portion. Therefore, the bending of the yarn 20 can be suppressed to the minimum level to prevent the degradation of the quality of the package 30.
  • the yarn hooking groove 71 of the yarn guide section 73 is configured such that the yarn 20 enters the yarn guide section 73 from the base end of the traverse arm 74. Therefore, even if the yarn 20 is pulled by the vibration and the inertia force during the traverse, the yarn 20 can be prevented from being disengaged from the yarn guide section 73. Since the yarn 20 is easily guided to the yarn guide section 73, the suspended yarn winding operation can quickly be resumed to improve the productivity of the automatic winder 1.
  • the slopes 73a and 73b are formed in the yarn guide section 73 in order to guide the yarn 20 to the opened section 71b of the yarn hooking groove 71. Accordingly, the yarn 20 can be smoothly guided to the yarn hooking groove 71 at the start of the winding and after the yarn joining, and the productivity of the automatic winder 1 can be improved.
  • the traverse driving motor 76 (output shaft 77) supports the traverse arm 74 such that the yarn guide section 73 is located farther away from the installation surface (perpendicular surface) than the base end. Therefore, the traverse arm 74 is arranged such that the yarn guide section 73 is located close to the contact line of the package 30 and the contact roller 29, and the free length and the print length can be shortened.
  • the traverse arm 74 includes the bent portion 72a that is bent in the direction towards the contact roller 29. Therefore, the free length and the print length can be shortened. As a result, the behavior of the yarn 20 wound into the package 30 can be stabilized, and the quality of the package 30 can be improved.
  • the automatic winder 1 of the present embodiment includes the package driving motor 41 that directly rotates the winding bobbin 22. Accordingly, the diameter of the contact roller 29 can be reduced compared with the configuration in which the package 30 is driven. Therefore, since the free length and the print length can be shortened, the behavior of the wound yarn 20 can be stabilized and the quality of the package 30 can be improved.
  • the automatic winder 1 of the present embodiment includes the yarn supplying section 11, the splicer device 14, and the upper yarn catching member 26.
  • the yarn supplying section 11 supplies the yarn 20 wound into the package 30.
  • the splicer device 14 connects the yarn end from the package 30 and the yarn end from the yarn supplying section 11.
  • the upper yarn catching member 26 can catch the yarn end from the package 30 by the upper yarn suction opening 35 to guide the yarn end to the splicer device 14.
  • the traverse arm 74 is supported by the traverse driving motor 76 (output shaft 77) such that at a position where the upper yarn suction opening 35 sucks and catches the yarn end from the package, the yarn guide section 73 is located more upstream in the yarn path than the upper yarn suction opening 35.
  • the yarn guide section 73 and the upper yarn suction opening 35 can be reliably prevented from making contact with one another and being broken. Additionally, it is not necessary to move the traverse arm 74 to the special retreat position when the upper yarn catching member 26 catches the yarn end. Therefore, for example, after the upper yarn catching member 26 catches the yarn end from the package 30, and the splicer device 14 performs an appropriate process, the winding operation of the yarn 20 can quickly be resumed. In case of the winder unit 10 of the present embodiment in which the yarn 20 is wound into the package 30 while being traversed by the traverse arm 74, since the traverse driving motor 76 swings the traverse arm 74, the width of the winding package 30 can freely be changed.
  • the package 30 can be formed while the yarn 20 is traversed to the position close to the end portions of the winding bobbin 22. Further, in the winder unit 10 of the present embodiment, the package 30 can also be formed while the yarn 20 is traversed within a narrow width in a region near the central portion in the axial direction of the winding bobbin 22.
  • the automatic winder 1 of the present embodiment includes the traverse fulcrum 27.
  • the traverse fulcrum 27 is a fulcrum of the traverse of the yarn 20 wound into the package 30.
  • the yarn path line L3 is the line connecting the traverse fulcrum 27 and the point P1 indicating the most upstream position of the yarn 20 on the contact roller 29, and the virtual line L2 is the line indicating the line along the longitudinal direction of the traverse arm 74.
  • the yarn path line L3 and the virtual line L2 form a substantially right angle.
  • the large bending of the yarn 20 wound into the package 30, which is caused by the yarn guide section 73, can be reduced even at the traverse stroke ends of the traverse arm 74.
  • the yarn 20 having little damage can be wound into the package 30 while preventing the yarn 20 from being disengaged from the yarn guide section 73.
  • the traverse arm 74 is supported by the traverse driving motor 76 with the output shaft 77 interposed therebetween such that the yarn guide section 73 is located in proximity of a position where the yarn 20 first contacts with the contact roller 29. Therefore, the free length and the print length can be shortened. As a result, because the behavior of the yarn 20 wound into the package 30 can be stabilized, the quality of the package 30 can be improved while preventing the generation of stitching or wrinkle.
  • the rotational axis line L1 of the traverse arm 74 is parallel to the yarn path line L3.
  • a rotational axis line L1a and a yarn path line L3a intersect at an angle ⁇ when the yarn path line L3a is extended towards the direction away from the package 30.
  • a virtual line L2a that is a line drawn from the base end portion of the traverse arm 74 to the yearn guide section 73 forms not right angle but substantially right angle with the yarn path line L3a.
  • substantially right angle means an angle in a relatively wide range including not only an angle extremely close to right angle but also an angle formed by the virtual line L2a and the yarn path line L3a of FIG. 5 .
  • an intersecting point P2 of the virtual line L2a and the yarn path line L3a (in other words, the position of the yarn guide section 73) is located more downstream in the yarn path than an intersecting point P3 of the yarn path line L3a and a perpendicular line L4a drawn from the base end portion of the traverse arm 74 to the yarn path line L3a.
  • the yarn guide section 73 is brought close to the contact line of the package 30 and the contact roller 29 by setting the traverse arm 74 to an appropriate length, the free length and the print length can be shortened. Therefore, the behavior of the yarn 20 wound into the package 30 can be stabilized, and the quality of the package 30 can be improved.
  • the angle ⁇ is an acute angle, and the bending of the yarn path at the traverse ends can be reduced as the angle ⁇ decreases (as the relationship between the rotational axis line L1a and the yarn path line L3a comes close to parallelism).
  • the virtual line L2 of the traverse arm 74 is inclined with respect to the installation surface of the winder unit 10.
  • the traverse arm 74 is arranged such that a virtual line L2b of the traverse arm 74 is parallel to the installation surface of the winder unit 10.
  • the traverse arm 74 may be arranged such that the virtual line L2b of the traverse arm 74 is substantially parallel to the installation surface of the winder unit 10.

  • the yarn guide section 73 of the second modification is arranged away from the contact line of the package 30 and the contact roller 29. Therefore, the layout of the above embodiment is preferably used form the viewpoint of shortening the free length and the print length.
  • the winder unit 10 can form packages having various shapes such as conical shape and tapered shape in addition to the cheese shaped package.
  • the shape of the yarn guide section 73 is not limited to shape of the above embodiment.
  • a yarn hooking groove with a long hole in which a distance from the opened section 71b to the terminal section 71a is lengthened may be formed. In this case, the yarn can effectively be prevented from being disengaged during the traverse.

  • the rotational axis line L1 of the traverse arm 74 may substantially be parallel to the yarn path line L3.
  • each of the winding unit main bodies 16 respectively includes the splicer device 14 and the upper yarn catching member 26.
  • a yarn splicing cart or the like may be provided, and when the yarn joining is required, the yarn splicing cart may move to the corresponding winding unit main body 16 to perform the yarn joining.
  • the effect of the present invention that the traverse arm 74 does not collide with the upper yarn catching member 26 even if the yarn joining operation is immediately started can be better exerted in the configuration of the above embodiment in which the yarn joining operation can be started without waiting the arrival of the yarn splicing cart.
  • the package driving control section 42 and the traverse control section 78 are provided independently of the unit control section 50.

  • the contact roller 29 may be formed in the conical shape similarly to the winding bobbin 22.

  • the diameter ratio of the large diameter side to the small diameter side is 1.6 or 1.8.
  • the difference in peripheral speed is generated between the package 30 and the contact roller 29, which sometimes causes the yarn 20 to slip on the contact roller 29. Therefore, by setting the diameter ratio of the large diameter side to the small diameter side in the contact roller 29, as compared to the configuration in which the contact roller 29 is formed in the cylindrical shape, the difference in peripheral speed generated between the contact roller 29 and the package 30 is reduced, and the slip of the yarn 20 printed on the contact roller 29 can be reduced. Accordingly, stitching that is likely to be generated in winding the yarn 20 into the conical package 30 can be prevented on the large diameter side, and high-quality package 30 can be formed.
