Definitions

  • the present invention relates to a take-up winding facility in which a winding machine winds a plurality of filament yarns (hereinafter simply referred to as yarns) spun out by a spinning machine, via a plurality of rollers.
  • one yarn feeding roller is located immediately before each take-up winding machine so that all of a plurality of yarns spun out by a spinning machine are guided from the yarn feeding roller to a plurality of bobbins installed in the take-up winding machine (see the Unexamined Japanese Patent Application Publication (Tokkai) No. 2003-285972 ).
  • two yarn feeding rollers are located immediately before each take-up winding machine so that a plurality of yarns spun out by a spinning machine are divisionally guided from the yarn feeding rollers to bobbins installed in the take-up winding machine and the number of which is the same as that of the plurality of yarns (see PCT National Publication No. 2005-534825 ).
  • the distance from the take-up winding machine to the yarn feeding roller located immediately before the take-up winding machine has to be increased in order to set the angle between the yarn path from the yarn feeding roller to the bobbin and the vertical direction to at most the predetermined value.
  • the height of the take-up winding device increases, resulting in a larger take-up winding facility. This disadvantageously increases building costs, degrades the operability of, for example, hooking of yarns on the rollers, and increases costs for air conditioning in the building.
  • the plurality of spun yarns are divisionally guided from the yarn feeding rollers to the bobbins in one take-up winding machine.
  • the angle between the yarn path from the yarn feeding roller to the bobbin and the vertical direction can be set to at most the predetermined value.

That is, an increase in the number of times the yarns are passed around the yarn feeding rollers 31, 32 reduces the rate of the difference in the number of contacts between the first yarn group 1a and the second yarn group 1b. This enables a reduction in variations in yarn quality.
  • the interlaces 70 are arranged between both the yarn feeding rollers 31, 32 and the take-up winding machine 21 in the vertical direction.
  • Each of the yarns 1 is provided in the yarn path extending from the corresponding yarn feeding roller 31, 32 to the corresponding bobbin 22.
  • Each of the interlaces 70 uses a liquid ejecting nozzle to entangle yarns forming the yarn 1 with one another so as to converge the yarns.
  • the interlace 70 thus inhibits the yarns from being spread or separated from one another.
  • Processing with the interlaces 70 is carried out after the yarn 1 is tensed.
  • the yarn 1 instead of being provided in the yarn path extending from the corresponding yarn feeding roller 31, 32 to the corresponding bobbin 22, the yarn 1 can be provided in a yarn path extending from the first yarn feeding roller 31 to the second yarn feeding roller 32 or a yarn path extending from the second yarn feeding roller 32 to the first yarn feeding roller 31.
  • the reason for the availability of these yarn paths is as follows.
  • the yarns I can be tensed during earlier ones of the plurality of operations of taking off and feeding out the yarns 1 between the spinning head 12 and the first yarn feeding roller 31 and between the yarn feeding rollers 31 and 32.
  • the processing with the interlaces 70 can be carried out without posing any problem.
  • the interlaces 70 can be utilized as yarn path guides.
  • the yarn paths are thus fixed to enable the yarns 1 to be stably wound.
  • the take-up winding machine 21 is located below the yarn feeding rollers 31, 32.
  • the take-up winding machine 21 uses the driving device 26 to rotate the bobbin holder shaft 23 on which the bobbins 22 are installed, to wind the yarns 1.
  • a plurality of the bobbins 22 are installed on the bobbin holder shaft 23.
  • each of the yarns 1 is traversed by a traverse support point guide 25a included in the traverse device 25, as described above. The yarn 1 is thus wound without being biased.
  • the angle A (see Figure 3 ) between the vertical direction and the yarn path of the outermost yarn 1 fed out from each of the yarn feeding rollers 31, 32 can be maintained at, for example, at most 20 degrees. This eliminates the need to increase the distance from the take-up winding machine to the yarn feeding roller located immediately before the take-up winding machine.
  • the take-up winding facility itself can thus be miniaturized.
  • this configuration enables a reduction in building costs, improvement of the operability of yarn hooking and the like, and a reduction in costs for air conditioning in the building. Furthermore, the present embodiment requires only two yarn feeding rollers, allowing the structure of the take-up winding facility to be simplified. This results in a cost reduction and the improved operability of yarn hooking and the like.
  • the first yarn feeding roller 31 is subjected to surface treatment such that the first yarn feeding roller 31 includes yarn contact portions 31a, 31b, ... each brought into contact with at least one of the first yarn group 1a and the second yarn group 1b.
  • the second yarn feeding roller 32 is subjected to surface treatment such that the second yarn feeding roller 32 includes yarn contact portions 32a, 32b, ... each brought into contact with at least one of the first yarn group 1a and the second yarn group 1b.
  • Figure 9A is a plan view focusing on the yarn feeding rollers 31, 32 and the yarns 1.
  • Figure 9B is a side view of the yarn feeding rollers 31, 32 and the yarns 1.
  • the surface treatment of the yarn contact portions 31a, ... of the first yarn feeding roller 31 and the yarn contact portions 32a, ... of the second yarn feeding roller 32 is normally a chromium plating treatment or formation of a ceramic film.
  • the present invention does not limit the treatment method. Any treatment method may be used provided that the method allows the yarn contact portions of each of the yarn feeding rollers 31, 32 to have different friction coefficients. Consequently, the appropriate treatment can also be achieved by varying a polishing process or a polishing duration.
  • the take-up winding facility according to the present invention has no withdraw roller as provided in conventional take-up winding facilities to withdraw the yarns I from the spinning head 12.
  • the first yarn feeding roller 31 can serve as a yarn withdrawing roller.
  • the appropriate tension can be applied to the yarns 1 even while the taken-off yarns I are being fed out from the first yarn feeding roller 31 to the second yarn feeding roller 32 or from the second yarn feeding roller 32 to the first yarn feeding roller 31.
  • the yarn contact portion 31a of the first yarn feeding roller 31, serving as a yarn withdrawing roller exhibits the greatest friction coefficient.
  • the friction coefficient of the yarn contact portions 31a, ..., 32a, ... decreases sequentially in conjunction with each operation of taking off and feeding out the yarns 1.
  • the friction coefficient for the specific values of the friction coefficient, applicable optimum values are determined depending on the desired yarn quality or the like. Thus, the numerical values of the friction coefficient are not limited. However, the friction coefficient may be sequentially increased depending on the yarn type.
