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 spun-out yarns are spread by the yarn feeding roller located immediately before the take-up winding machine and are then wound around a plurality of bobbins installed in the take-up winding machine (see the Unexamined Japanese Patent Application Publication (Tokkai) No. 2003-285972 ).
  • the spread angle of the yarns between the yarn feeding roller located immediately before the take-up winding machine and each of the bobbins installed in the take-up winding machine (the spread angle is the angle between the yarn path from the yarn feeding roller to the bobbin and the vertical direction) is set to at most a predetermined value. This is because when the spread angle is larger than the predetermined value, the friction between the yarns and a guide configured to spread the yarns becomes more serious, varying yarn quality among the plurality of bobbins.
  • a plurality of yarn feeding rollers arranged immediately before a take-up winding machine are provided for each take-up winding machine.
  • a plurality of yarns spun out by the spinning machine are distributively 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, and are then wound around the bobbins (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.
  • take-up winding device-height increases, resulting in a larger take-up winding facility.
  • the larger take-up winding facility disadvantageously contributes to increasing the costs of a building in which the take-up winding facility is installed, degrading the operability of yarn hooking and the like, and increasing costs for air conditioning in the building in which the take-up winding facility is installed.
  • the operation of spreading the yarns is shared by the plurality of yarn feeding rollers.
  • the spread angle of the yarns can be set to at most the predetermined value even with an increase in the number of bobbins installed in one take-up winding machine.
  • the take-up winding facility can therefore be miniaturized.
  • a separate yarn feeding roller needs to be provided which takes off the yarns spun out by the spinning machine.
  • the yarn feeding rollers are densely arranged close to the take-up winding machine, thereby complicating the take-up winding facility.
  • WO 2005/052 225 A1 discloses an apparatus falling within the scope of the preamble to Claim 1 below.
  • US Patent 4,318,676 discloses an apparatus falling within the scope of the preamble to Claim 1 below.
  • WO 2006/126 413 A1 and US Patent 3,844,496 each may have relevance for understanding the background to the present invention.
  • An object of the present invention is to provide a take-up winding facility which is miniaturized by reducing the take-up winding device height and which is simplified by simplifying the layout of vicinity of the take-up winding machine.
  • Embodiments of present invention are able to exert the following effects.
  • the operation of spreading the yarns is shared by the plurality of yarn feeding rollers arranged immediately before the take-up winding machine. This reduces the number of yarns to be spread by one yarn feeding roller and thus the distance over which the yarns are spread by one yarn feeding roller. As a result, the spread angle of the yarns can be set to at most a predetermined value even with an increase in the number of bobbins installed in one take-up winding machine. Thus, a variation in yarn quality among the plurality of bobbins can be reduced to ensure yarn quality. Such embodiments also eliminate 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 device height decreases, resulting in a smaller take-up winding facility. This serves to reduce the costs of a building in which the take-up winding facility is installed, improve the operability of yarn hooking and the like, and reduce costs for air conditioning in the building in which the take-up winding facility is installed.
  • each of the yarn feeding rollers provides both the function of taking off the yarns spun out by the spinning machine and the function of feeding out the yarns to the take-up winding machine. This eliminates the need to provide a separate yarn feeding roller configured to take off the yarns spun out by the spinning machine, between the spinning machine and the yarn feeding roller located immediately before the take-up winding machine. This in turn prevents the yarn feeding rollers from being densely arranged close to the take-up winding machine, thus allowing the take-up winding facility to be simplified.
  • each of the yarn feeding rollers can reliably take off the yarns spun out by the spinning machine.
  • the yarn feeding roller can also take off the yarns fed out from the other yarn feeding rollers to reliably feed out the yarns to the take-up winding machine.
  • the friction coefficient of the yarn contact portion corresponding to a yarn group take-off portion is different from that of the yarn contact portion corresponding to a yarn group feed-out portion.
  • the roller diameter of the yarn group take-off portion is different from that of the yarn group feed-out portion.
  • the tension applied to the yarns is optimized, ensuring the appropriate yarn quality and enabling stable yarn winding.
  • the yarns can be temporarily held before being hooked on each of the yarn feeding rollers.
  • a yarn hooking operation is facilitated.
  • the interlace located between the yarn feeding rollers, or between each of the yarn feeding rollers and the take-up winding machine allows the yarn path to be fixed. This enables stable yarn winding.
  • the oiling device can be installed away from the take-up winding machine.
  • the layout of vicinity of the take-up winding machine can be simplified.
  • the migration nozzle can be installed away from the take-up winding machine.
  • the layout of vicinity of the take-up winding machine can be simplified.
  • the shutter can be installed away from the take-up winding machine.
  • the layout of vicinity of the take-up winding machine can be simplified.
  • the yarn feeding rollers can be easily controlled. This enables a reduction in the number of components required and thus in costs.
  • the spinning machine can be located below the yarn feeding rollers with the same level of yarn quality maintained. Furthermore, the plurality of yarns spun out by the spinning machine can be fed to the yarn feeding rollers so as to be evenly distributed between the yarn feeding rollers.
