Description

ELASTIC YARN TAKE UP WINDING APPARATUS AND METHOD AND ELASTIC YARN PACKAGE WINDED BY THE SAME}

The present invention relates to a yarn winding machine of the elastic yarn, and a winding method thereof, and an elastic yarn winding body wound through the yarn, and more particularly, the initial portion of the yarn when the yarn is switched to the ball bobbin is wound on the end outside the winding width of the ball bobbin. The last part of the yarn, the bunch yarn, is wound around the end of the winding width so that the initial part of the yarn can be easily found and the replacement of the package can be carried out continuously, thereby reducing the yarn loss and the yarn winding machine of the elastic yarn to reduce the loss. And it relates to the elastic yarn wound body wound through this.

As a general elastic yarn winding machine, the turret plate with two bobbin holders is rotated to perform the position exchange of the bobbin holders, and when the package becomes full, the turret type wind winding machine which winds the yarn continuously by changing the yarn to the ball bobbin is mainly used. It became.

Referring to the doping (doffing) order of the prior art Korean Patent Publication No. 95-11301 with reference to Figure 1, first, as shown in Figure 1 (a) when the package 4 is full volume as shown in Figure 1 (b) Rotate the turret 6 to exchange the positions of the full package 4 and the ball bobbin 7, and then rotate the turret 6 as shown in FIG. The ball bobbin 7 is rotated and stopped at M '. Then, the swing guide plate 9 for transferring the elastic yarn 3 to the ball bobbin 7 is rotated, and the bobbin holder 5 with the all-round package 4 is braked suddenly to loosen the yarn. Pull on the bobbin (7) surface. When the yarn is pulled to the surface of the ball bobbin (7), the thread is trimmed by the clamping force between the ball bobbin (7) and the universal package (4), and the next elastic yarn is wound on the yarn pulled to the ball bobbin (7). The changeover is complete. Subsequently, after the swing guide plate 9 is returned, the ball bobbin 7 is returned to the winding position 'A' as shown in FIGS. 1 (d) and 1 (e) and wound while traversing through the traverse device 2. do.

However, the above-described prior art Korean Patent Publication No. 95-11301 cannot replace the package continuously because it can only be found after completely dissolving the yarn in the package in order to find the initial part of the yarn in the full volume package when switching to the bobbin. As a result, it is inevitable that some residues remain in the bobbins used, so that the loss of yarn occurs.

Another problem of the above-described Korean Patent Publication No. 95-11301 is that it is not easy to find a bunch of yarns because of the occurrence of a bunch of yarns at the center of the surface of the full package, as shown in FIG. Because of this difference, it should be removed, but because of the presence of bunching yarn in the center of the surface of the package, the surface is damaged.

However, the four-switching method of the prior art Korean Patent Application Publication No. 98-63557 described above is the same as the above-described Korean Patent Publication No. 95-11301, and the elastic yarn is separated from the traverse device by four-switching by the tightening force between the bobbin and the ten thousand package. It is difficult to wind the initial part of the yarn at the end of the bobbin by changing the thread with the swing guide plate. There was a problem that continuous package replacement is not made smoothly.

Another problem of the above-described Korean Patent Laid-Open Publication No. 98-63557 is that when a swing guide plate is transferred during four changeovers, a sudden braking is applied to a bobbin holder with a full-volume package, so that the four-switching is made by the clamping force between the empty bobbin and the full-volume package. If the yarn is thick, not only is it difficult to cut, but both ends of the yarn are damaged, which makes it impossible to use.

Accordingly, the present invention has been made to solve the conventional problems as described above, one object of the present invention is to allow the initial portion of the elastic yarn to be wound on the end outside the winding width of the ball bobbin to enable continuous package exchange, An object of the present invention is to provide a yarn winding machine for elastic yarn and a method of winding the same so that no residue remains on the bobbin so as to eliminate loss of yarn.

Another object of the present invention is to cut the elastic yarn by using a separate cutting device when changing the yarn to facilitate the cutting of the yarn irrespective of the thickness of the yarn, to prevent damage to both ends of the elastic yarn during the yarn cutting to eliminate the loss of the yarn An elastic yarn winding machine for giving and a winding method thereof are provided.

First, when the bobbin 200 mounted on the bobbin holder 301 in the wound position as shown in FIG. 7 (a) is in a full winding state, the position exchange means 400 is shown in FIGS. 7 (b), 8 (a) and As shown in FIG. 8 (b), the bobbin holder 301 of the winding position a and the bobbin holder 302 of the standby position b are rotated and rotated about the rotation shaft 401 to stop (S1). At this time, the position of the ball bobbin 200 may be stopped at the intermediate position m after the winding position a.

Subsequently, the swing guide device 700 surrounds the ball bobbin 200 at the wound position a, as shown in FIGS. The elastic yarn 10 that is advanced and traversed between the packages A is guided to an end portion in the winding width of the winding package A (S2). At this time, the elastic yarn 10 is wound in the winding package (A) through the groove 711 on the swing guide plate 710, the position of the groove 711 on the swing guide plate 710 is full winding It is just above the end of the package (A). Therefore, when cutting the yarn of the elastic yarn 10, the bunching yarn (unnecessary yarn) is wound to the end of the winding package (A).

Thereafter, the first sital plate 810 of the cytal device 800 is rotated toward the quench roller 500 as shown in FIGS. 7 (d) and 8 (c) to the traversing device 100. ) To separate the elastic yarn (10). At this time, if the elastic yarn 10 is not separated from the traverse guide 101, the initial portion X of the yarn 10 cannot be wound at the expected position of the present invention. Subsequently, the first cytal plate 810 advances the elastic yarn 10 fitted into the groove 811 in front of the front of the spinner as shown in FIGS. 7E and 8D, and thus the standby position b. Move to the end of the winding width of the ball bobbin 200 in (S3).

After the above-mentioned sital step (S3), the siphon guide 720 on the swing guide plate 710 moves forward the elastic yarn 10 in front of the spin-winder as shown in FIGS. 7 (f) and 8 (e). At this time, the elastic yarn 10 that is caught in the groove 711 of the swing guide plate 710 and the locking groove 721 of the siphon guide 720 is cut by the cutting device 730 (S4). ). The cutting device 730 is formed in the shape of a scissors as shown in Figure 5, the elastic yarn when the groove 711 of the swing guide plate 710 and the engaging groove 721 of the sisong guide 720 is matched Cut 10. At this time, the small blade of the cutting device 730 is rotatably connected to the sisong guide 720, the small blade of the cutting device 730 as the sisong guide 720 is moved Retracted or spread Here, the elastic yarn 10 between the groove 811 of the first sital plate 810 advanced forward of the winder and the siphon guide 720 on the swing guide plate 710 flows without bending. . Therefore, the elastic yarn 10 is wound around the end of the winding width of the wound winding package (A), and then cut to the end outside the winding width of the ball bobbin 200. At this time, when the yarn 10 is cut without the siphon guide 720 on the swing guide plate 710, because the elastic yarn 10 is an elastic circle, the yarn 10 is bounced off the end of the ball bobbin 200. It becomes difficult to wind. Therefore, it is easy to cut by applying tension to the yarn 10 when cutting the yarn by installing the siphon guide 720 on the swing guide plate 710, winding the yarn 10 to the end of the ball bobbin 200 It becomes possible.

Thereafter, the first cytal plate 810 retreats backward as shown in FIGS. 7G and 8F, and then returns the elastic yarn 10 to the inside of the traverse guide 101. At this time, the siphon guide 720 and the cutting device 730 on the swing guide plate 710 are also returned to the original position, the lifting frame 600 is lowered as shown in FIG. 7 (h), and finally the swing Since the guide plate 710 is returned to its original state, four switching is completed (S5). Thus, the elastic yarn 10 is moved into the winding width of the ball bobbin 200.

The elastic yarn winding body 900 manufactured in this way is capable of continuous exchange between the winding bodies as shown in FIG. 9, and thus can be used in stockings manufacturing, warp knitting machines, circular knitting machines, and the like to reduce the loss of yarn.

In addition, the shape of the bobbin 200 of the elastic yarn winding body 900 may be used in a general form, but preferably, a portion in which the initial portion X of the yarn 10 is wound, that is, a slit on the outer peripheral surface of the end outside the winding width. It is good to have 201. This is because, if the slit 201 is absent, the initial portion X of the elastic yarn 10 may be wound around the bobbin 200 and bounced off.

Although the present invention has been described in more detail with reference to some embodiments, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.

As described above, according to the spinning machine of the present invention and the method of winding the elastic yarn according to the present invention, and the elastic yarn winding body wound through the same, the initial portion of the elastic yarn is wound on the end outside the winding width of the hollow bobbin, thereby enabling continuous package exchange. It prevents the loss of yarn by leaving no residue on the bobbin, and makes it easy to cut the yarn regardless of the thickness of the yarn by cutting the elastic yarn by using a separate cutting device when changing the yarn. It has an excellent effect of preventing the loss of yarn by preventing damage.
