Description

  The present invention relates to a spinning and winding facility in which a plurality of yarns spun from a spinning machine are wound by a winding machine via a plurality of rollers.

  As a conventional spinning winding device, one yarn feeding roller arranged immediately before the winding machine is provided for one winding machine, and all of a plurality of spun yarns are spun. There is one in which it is diffused by the one immediately preceding yarn feed roller and wound by a plurality of bobbins mounted on one winder (see Patent Document 1).

  In the spinning winding facility shown in Patent Document 1, the spreading angle of the yarn from the immediately preceding yarn feeding roller to the bobbin attached to the winding machine (the angle formed by the yarn path from the yarn feeding roller to the bobbin and the vertical direction). Is larger than a predetermined angle, the friction of the yarn with respect to the guide for diffusing the yarn increases, which affects the variation in yarn quality among the plurality of bobbins. Therefore, the spreading angle of the yarn is set to be equal to or smaller than the predetermined angle.

On the other hand, as another example of the conventional spinning winding equipment, a plurality of yarn feeding rollers arranged immediately before the winding machine are provided for one winding machine, and spinning is performed from the spinning machine. A plurality of yarns are distributed and guided from each yarn feed roller to the same number of bobbins as the plurality of yarns mounted on one winder, and wound up. (See Patent Document 2).

And since the width | variety which spreads a some thread | yarn with one yarn feed roller becomes wide, the spreading angle of the said yarn becomes larger than a predetermined angle. Therefore, in the spinning and winding equipment shown in Patent Document 1, in order to set the yarn spreading angle to a predetermined angle or less, the distance from the winding machine to the immediately preceding yarn feed roller must be increased. For this reason, there is a problem that the height of the apparatus is increased and the equipment is enlarged. As the equipment becomes larger, there are problems such as an increase in the cost of the building for installing the equipment, a decrease in workability such as stringing, and an increase in the cost of air conditioning in the building where the equipment is installed.

  On the other hand, in the spinning and winding equipment shown in Patent Document 2, the number of yarns diffused by a single yarn feed roller is reduced because the yarns are spread by a plurality of yarn feed rollers. The width of spreading a plurality of yarns with a single yarn feed roller is reduced, and even if the number of bobbins attached to one winder is increased, the yarn spreading angle is kept below a predetermined angle. be able to.

  Next, the yarn winding equipment 100 according to the second embodiment of the present invention will be described. In the following description, the same reference numerals are assigned to the same components as those of the take-up winding device 100 according to the first embodiment, and the description of the components is omitted. FIG. 5 is a plan view of the yarn feeding rollers 30 and 31 of the yarn winding equipment 100 according to the second embodiment of the present invention.

  As shown in FIG. 5, the first yarn feed roller 30 is configured so that the friction coefficient of the yarn contact portion in contact with the first yarn group 2 and the friction coefficient of the yarn contact portion in contact with the second yarn group 3 are relatively different. The roller peripheral surface of the first roller portion 30b is surface-treated.

  Specifically, on the roller circumferential surface of the first roller portion 30b of the first yarn feed roller 30, the first yarn group 2 is a spinning portion 10 that is in contact with the first yarn group 2 of the first roller portion 30b. The base end side portion 30c corresponding to the portion to be pulled from (the take-up portion) is a mirror finish that increases the coefficient of friction with respect to the yarn 1, and is a yarn contact portion in contact with the second yarn group 3 of the first roller portion 30b. The tip side portion 30d corresponding to the portion (feeding portion) for feeding the two yarn groups 3 to the winder 22 is finished with a satin finish with a small friction coefficient with respect to the yarn 1.

  Similarly, as shown in FIG. 5, the second yarn feed roller 30 has a relative friction coefficient between the yarn contact portion in contact with the first yarn group 2 and the friction coefficient of the yarn contact portion in contact with the second yarn group 3. The roller peripheral surface of the second roller portion 31b is surface-treated so as to be different.

  Specifically, on the roller circumferential surface of the second roller portion 31b of the second yarn feeding roller 31, the second yarn group 3 is a spinning portion 10 that is in contact with the second yarn group 3 of the second roller portion 31b. The tip end portion 31d corresponding to the portion to be pulled from (the take-up portion) is a mirror finish that increases the coefficient of friction with respect to the yarn 1, and is a yarn contact portion in contact with the first yarn group 2 of the second roller portion 31b. A base end side portion 31c corresponding to a portion (feeding portion) for feeding the yarn group 2 to the winder 22 is finished with a satin finish with a small friction coefficient with respect to the yarn 1.

  In this way, the mirror-finishing that increases the friction coefficient of the take-up portion is achieved by making the roller peripheral surfaces of the roller portions 30b and 31b difficult to slide with respect to the yarn 1 so that the yarn feeding rollers 30 This is because the rotational driving force 31 is reliably transmitted to the yarn 1. The reason why the finish portion has a satin finish with a small friction coefficient is to alleviate fluctuations in the tension of the yarn 1 in the winder 22.

  The surface treatment of the roller peripheral surface of each of the roller portions 30b and 31b is not limited to the mirror finish and the satin finish, and the first yarn feed roller 30 is the roller periphery of the portion in contact with the first yarn group 2. For the second yarn feed roller 31, the friction coefficient of the roller peripheral surface of the portion in contact with the second yarn group 3 is such that the friction coefficient of the surface is greater than the friction coefficient of the roller peripheral surface of the portion in contact with the second yarn group 3. The surface treatment method is not particularly limited as long as the roller peripheral surfaces of the roller portions 30b and 31b are surface-treated so as to be larger than the friction coefficient of the roller peripheral surface of the portion in contact with the first yarn group 2. Further, depending on the yarn type, the friction coefficient may be reversed.

  Next, the yarn winding equipment 100 according to the third embodiment of the present invention will be described. In the following description, the same reference numerals are assigned to the same components as those of the take-up and winding equipment 100 according to the first and second embodiments, and the description of the components is omitted. 6A is a plan view of the yarn feeding rollers 30 and 31 of the take-up winding facility 100 according to the third embodiment of the present invention, and FIG. 6B is a plan view of the spin winding device 100 according to the third embodiment of the present invention. FIG. 6C is a side view of the yarn path of one yarn group 2 and each of the yarn feeding rollers 30 and 31, and FIG. -It is a side view of 31.

  As shown in FIGS. 6A and 6B, in the first yarn feed roller 30, the roller diameter of the yarn contact portion in contact with the first yarn group 2 and the roller diameter of the yarn contact portion in contact with the second yarn group 3 are relatively different. . Specifically, the roller of the tip side portion 30d corresponding to the portion of the first yarn feed roller 30 that contacts the second yarn group 3 and that feeds the second yarn group 3 to the winder 22 (feeding portion). From the roller diameter of the base end side portion 30c corresponding to the portion of the first yarn feed roller 30 in contact with the first yarn group 2 that is in contact with the first yarn group 2 and that takes the first yarn group 2 from the spinning machine 10 (take-up portion). It is getting bigger.

  Similarly, as shown in FIGS. 6A and 6C, in the second yarn feed roller 31, the roller diameter of the yarn contact portion in contact with the first yarn group 2 and the roller diameter of the yarn contact portion in contact with the second yarn group 3 are different. . Specifically, the proximal end portion 31c corresponding to a portion of the second yarn feed roller 31 that contacts the first yarn group 2 and that feeds the first yarn group 2 to the winder 22 (feeding portion). From the roller diameter of the tip side portion 31d corresponding to the portion of the second yarn feed roller 31 in contact with the second yarn group 3 that contacts the second yarn group 3 and that takes the second yarn group 3 from the spinning machine 10 (take-up portion). It is getting bigger.

  In this way, the roller diameter of the feeding portion is made larger than the roller diameter of the take-up portion because the peripheral speed of each of the yarn feeding rollers 30 and 31 in the sending portion of each yarn group 2 and 3 is set to the take-up portion of each yarn group 2 and 3. It is for making it faster than the peripheral speed of each yarn feed roller 30 * 31.

  In addition, each thread | feeding roller 30 * 31 of the spinning winding equipment 100 which concerns on 4th Embodiment is each roller part 30b similarly to each thread | feeding roller 30 * 31 of the spinning winding equipment 100 which concerns on 3rd Embodiment. -Of the roller peripheral surface of 31b, the surface of the take-up portion of each yarn group 2 and 3 is mirror-finished, and the surface diameter of the send-out portion of each yarn group 2 and 3 is matte finish, and the roller diameter of the part that has undergone pear finish May be larger than the roller diameter of the mirror-finished portion.
