Definitions

  • the present invention relates to a take-up winder.
  • the Examined Japanese Patent Application Publication (Tokko-Hei) No. 2-41490 refers to a conventional take-up winder.
  • the take-up winder sequentially winds synthetic filament yarns (hereinafter simply referred to as yarns) spun by a spinning section 2, around a first godet roller 3 and a second godet roller 4 in order.
  • the take-up winder then uses traverse support point guides 6 and reciprocating traverse guides 16 to traverse the yarns fed from the second godet roller 4, while winding the yarns on winding bobbins 7.
  • a plurality of packages P are simultaneously formed.
  • the winding bobbins 7 are supported by a bobbin holder 5.
  • the plurality of winding bobbins 7 are juxtaposed along the axial direction of the winding bobbins.
  • the juxtaposition direction of the winding bobbins 7 is parallel to the axial direction of the second godet roller 4.
  • a yarn path regulating guide 15 is provided downstream side of and immediately close to the second godet roller 4 to regulate the yarn paths of the yarns.
  • the traverse guide 16 reciprocates to traverse each of the yarns with respect to the winding bobbin, while winding the yarn around the winding bobbin. Eventually, a package is formed.
  • the bend angle ⁇ of the yarn at each of the guides has a value varying with the guide.
  • the bend angle ⁇ of the yarn at the traverse support point guide 6 increases from the center of the bobbin holder 5 toward the end of the bobbin holder in a direction in which the bobbin holder extends. This also applies to the bend angle of the yarn at the yarn path regulating guide 15.
  • the length of the bobbin holder 5 has recently tended to be further increased as shown in Figure 2 .
  • the bend angle ⁇ of the yarn at the traverse support point guide 6, corresponding to the end of the bobbin holder has further been increased.
  • an increase in bend angle ⁇ causes the quality of the yarn to be degraded.
  • the present applicant sets a predetermined upper limit value (for example, 15 degrees) for the bend angle ⁇ for management.
  • the above-described tendency to increase the length of the bobbin holder hinders implementation of a layout allowing the bend angle ⁇ , particularly the bend angle ⁇ of the yarn at the traverse support point guide, corresponding to the end of the bobbin holder, to be set equal to or smaller than the upper limit value (hereinafter referred to as a management upper-limit bend angle ⁇ k)
  • the yarn path regulating guide 15, located downstream side of and immediately close to the second godet roller 4 may be placed away from the traverse support point guides 6. That is, the second godet roller 4 may be installed at a higher position. Then, as shown by reference numeral ⁇ 2 in Figure 2 , the bend angle ⁇ of the yarn at the traverse support point guide 6, corresponding to the end of the bobbin holder 5, can be set to such a small value as shown in Figure 1 .
  • installing the second godet roller 4 at a higher position as described above increases the construction costs of a building in which the take-up winder is accommodated. This also degrades operability and reduces cooling and heating efficiency.
  • JP 61 027 875 discloses a take-up winder falling within the scope of the preamble to Claim 1 below.
  • a main object of the present invention is to provide a technique for reducing the need to install the second godet roller at a higher position under the precondition that the bend angle ⁇ of the yarn at the guide is set equal to or smaller than the management upper-limit bend angle ⁇ k and that increasing the number of guides compared to that in the conventional example shown in Figure 1 is avoided.
  • some of the plurality of yarns traveling from the second godet roller toward the traverse support point guides may be bent at the traverse support point guides by more than the predetermined angle (management upper-limit bend angle) determined in view of the quality of the yarns.
  • the predetermined angle management upper-limit bend angle
  • such yarns can be bent by the respective guides provided upstream side of and close to the corresponding traverse support point guides. This allows the bend angle of each of the yarns at the corresponding traverse support point guide to be set equal to or smaller than the management upper-limit bend angle.
  • the yarn appears to be bent by more than the management upper-limit bend angle, thus enabling a reduction in the height of the installation position of the second godet roller. Furthermore, the actual yarn is bent in two stages by the traverse support point guide and the guide provided upstream side of and close to the traverse support point guide, and each bend angle does not exceed the management upper-limit bend angle. Thus, the yarn quality is prevented from being degraded.
  • both the bend angle of the yarn at the traverse support point guide and the bend angle of the yarn at the above-described guide are set equal to the management upper-limit bend angle. Then, since the above-described guide is located upstream side of and "close" to the traverse support point guide, the yarn appears, in broad perspective, to be bent at the traverse support point guide by an angle that is double the management upper-limit bend angle.
  • the axial direction of the second godet roller is different, by 90 degrees, from that in the conventional example shown in Figure 1 . This eliminates the need for the yarn path regulating guide provided in the conventional example.
  • the above-described configuration meets the precondition that the bend angle ⁇ of the yarn at the guide is set equal to or smaller than the management upper-limit bend angle ⁇ k and that increasing the number of guides compared to that in the conventional example shown in Figure 1 is avoided.
  • the above-described configuration can still reduce the need to install the second godet roller at a higher position.
  • the reduced need to install the second godet roller at a higher position collaterally alleviate the following problems: increased construction costs of the building in which the take-up winder is accommodated, degraded operability, reduced cooling and heating efficiency, and the like.
  • the above-described take-up winder may be further configured as follows.
  • An interlace nozzle is provided between the second godet roller and each of the traverse support point guides to interlace the yarn.
  • the interlace nozzle includes a nozzle main body interlacing the yarn and paired nozzle guides arranged to sandwich the nozzle main body therebetween.
  • One of the paired nozzle guides is used as the guide.
  • the other of the paired nozzle guides is not used to bend the yarn.
  • This configuration has the advantage of being able to reduce the number of guides in the configuration into which the interlace nozzles are introduced.
  • the other of the paired nozzle guides is not used to bend the yarn, increasing the number of guides compared to that in the conventional example shown in Figure 1 is avoided.
  • the quality of the yarn is prevented from being degraded.
  • the above-described take-up winder may be further configured as follows. For each of the yarns bent at the respective traverse support point guides by at most the predetermined angle, a yarn tension applying guide applying tension to the yarn is provided. That is, the yarns bent at the respective traverse support point guides by at most the predetermined angle may be subjected to an insufficient tension. Thus, the above-described configuration allows the tension of the yarn to be compensated for. Furthermore, even though the need for the yarn path regulating guide is eliminated, the number of guides allowing the yarn to be bent need not be increased compared to that in the conventional example shown in Figure 1 . Thus, in terms of the resistance of the guide to the yarn, the quality of the yarn is prevented from being degraded.
  • the above-described take-up winder may be further configured as follows.
  • the guide is not provided. In this manner, this configuration positively avoids providing the guides for the yarns that do not necessarily require the guides. This configuration enables a reduction in the number of guides compared to that in the conventional example shown in Figure
  • Figure 3 is a front view of a take-up winder according to the first embodiment of the present invention.
  • the take-up winder 1 according to the present embodiment includes a spinning section 2, a first godet roller 3 and a second godet roller 4, a bobbin holder 5, and traverse support point guides 6 as main components.

  • the first godet roller 3 and the second godet roller 4 thus take off the yarns Y.
  • the first godet roller 3 is located below the spinning section 2 in the vertical direction.
  • the first godet roller 3 is installed as follows in order to allow the plurality of yarns Y spun by the spinning section 2 to be wound around the first godet roller 3 while keeping parallel to one another. That is, the first godet roller 3 is installed such that the axial direction 3j thereof is parallel to the planar direction of a spinning plane that can be defined as a plane containing all the yarn paths of the plurality of yarns Y spun by the spinning section 2 and that the axial direction 3j corresponds to the horizontal direction.
  • the second godet roller 4 is located above the first godet roller 3 so that the axial direction 4j of the second godet roller 4 is orthogonal to the axial direction 3j of the first godet roller 3 and corresponds to the horizontal direction.
  • the axial direction 3j of the first godet roller 3 is in an orthogonal relationship with the axial direction 4j of the second godet roller 4 as seen in a plan view of the yarn winder 1.
  • the inter-godet yarn traveling plane that can be defined by the plurality of yarns between the first godet roller 3 and the second godet roller 4 is twisted by 90 degrees in an S twist (or Z twist) direction as the yarns Y travel from the first godet roller 3 to the second godet roller 4.
  • the bobbin holder 5 rotatably supports a plurality of (in the present embodiment, 12) take-up bobbins 7 (winding bobbins) around which the yarns Y fed from the second godet roller 4 are wound.

  • the axial direction 5j of the bobbin holder 5 is set to be orthogonal to the axial direction 4j of the second godet roller 4 and to correspond to the horizontal direction.
  • the axial direction 4j of the second godet roller 4 is orthogonal to the axial direction 7j of the plurality of take-up bobbins 7 supported by the bobbin holder 5 as seen in a plan view of the take-up winder 1.
  • the traverse support point guides 6 are arranged between the second godet roller 4 and the take-up bobbins 7 to set traverse support points for traversing of the yarns Y fed from the second godet roller 4 with respect to the take-up bobbins 7. Specifically, a plurality of the traverse support point guides 6 are juxtaposed in the same direction as the axial direction 5j of the bobbin holder 5 on a one-to-one relationship with the take-up bobbins 7. Each of the traverse support point guides 6 is configured to completely enclose the periphery of the traveling yarn Y, for example, as shown in Figure 6B so as to prevent the yarn Y from slipping out from the guide during traversing.

  • Each of the yarns Y guided to the traverse support point guide 6 is wound on the take-up bobbin 7 while being traversed by the traverse device (not shown in the drawings).
  • a package P with a predetermined shape and a predetermined size is formed on each of the take-up bobbins 7.
  • a management upper-limit bend angle ⁇ k will be described.
  • An increase in the bend angle ⁇ of the yarn Y at the guide causes the quality of the yarn Y to be more severely degraded by the bending. Consequently, the bend angle ⁇ of the yarn Y at the guide cannot be set to a random large value.

  • the interlace nozzle 11 includes a nozzle main body 12 interlacing the yarn Y, and paired nozzle guides 13a, 13b arranged so as to sandwich the nozzle main body 12 therebetween.
  • the nozzle guides 13a, 13b inhibit the yarn Y traveling through the nozzle main body 12 from flapping.
  • each of the nozzle guides 13a, 13b is configured as a U-shaped ceramic guide that does not completely enclose the periphery of the traveling yarn Y.
  • the upstream side nozzle guide 13a of the paired nozzle guides 13a, 13b is used as the close guide 9.
  • the other nozzle guide 13b of the paired nozzle guides 13 is not used to bend the yarn Y. That is, the nozzle guide 13b only lies along the yarn path of the yarn Y.
  • the take-up winder 1 is further configured as follows.
  • the interlace nozzle 11 is provided between the second godet roller 4 and each of the traverse support point guides 6 to interlace the yarn Y.
  • the interlace nozzle 11 includes the nozzle main body 12 interlacing the yarn Y and the paired nozzle guides 13a. 13b arranged to sandwich the nozzle main body 12 therebetween.
  • the upstream side nozzle guide 13a of the paired nozzle guides 13a, 13b is used as the close guide 9.
  • the downstream side nozzle guide 13b of the paired nozzle guides 13 is not used to bend the yarn Y. This configuration has the advantage of being able to reduce the number of guides in the configuration into which the interlace nozzles 11 are introduced.
  • downstream side nozzle guide 13b of the paired nozzle guides 13a, 13b is not used to bend the yarn Y, increasing the number of guides compared to that in the conventional example shown in Figure 1 is avoided.
  • the quality of the yarn Y is prevented from being degraded.
