The present invention relates to a stripe knitting yarn supply apparatus, and more specifically, it is possible to accurately supply and stop various color yarns with a circular knitting machine in accordance with a predetermined stripe while maintaining a constant yarn tension. The present invention relates to a stripe knitting yarn feeder capable of further enhancing the quality of the grains.

The yarn supplied by the circular knitting machine varies depending on the bobbins and cylinders on which he is wound, as well as the size of the bobbins and cylinders. Since it is non-uniform, it is usually equipped with a number of separate yarn feeder in accordance with the fabric and color to be knitted to adjust the yarn tension is constant during knitting.

Basically, the yarn feeder includes two or more up and down drive wheels having different speeds, and a cylindrical yarn feed krill supplied to the circular knitting machine while the yarns dissolved from the yarn source are wound several times on the surrounding surface according to the rotation of the drive wheel. creel), and a driving shaft and a guide member for rotating the creel.The yarn feeder is configured to smoothly feed the yarn under moderate tension in order to increase the speed of the knitting machine and does not adversely affect the knitting fabric during trimming. . However, the simple feeding mechanism of the yarn feeder contributes greatly to the uniform knitting by maintaining the yarn tension at the time of knitting the plain fabric. Can't.

Therefore, when knitting multicolor stripes, a yarn feeder as in US Pat. No. 5,388,747 shown in Fig. 13 is mainly used.

Although there are some differences depending on the color of the stripe, the yarn feeder as shown in FIG. 13 is generally used by being mounted per 200 circular knitting machines, and as in the basic plain yarn feeder, driving wheels 15a and 15b, It consists of a key roller 16, drive shaft 14 and the housing (1) for supporting them, and is configured to be fixed to the rail of the circular knitting machine through the bolt (2), the creel of the four feed drum in accordance with the chromaticity of 4 to 6 degrees (3a) (3b) (3c) and (3d) are connected below several, and it is comprised so that a color yarn may be supplied appropriately through the said control lever 40 of each krill.

When the color yarn is changed according to the pattern, for example, when only the color yarn of the krill 3a is to be supplied and the color yarn wound on the remaining krill 3b, 3c, 3d does not need to be supplied, Only the krill 3a to which the yarn is supplied should be operated, but these krills 3a, 3b, 3c and 3d are operated simultaneously through the same drive shaft 14, so that the krill 3b to which the yarn is not supplied ( Even 3c) and 3d are idle. Therefore, the yarn is entangled or wound around the idling krill, and the krill is connected in the longitudinal direction, so the contamination caused by dust or the like generated during the yarn movement is also large.

In particular, this phenomenon is prominent in the case of synthetic fiber spun yarns, and a lot of lint is generated on the surface of yarns due to idling, resulting in unnecessary streaks or knots in the knitted fabric, and the quality of knitted fabrics is poor. There was a tendency to decrease.

In addition, rubber rings are mounted on the surfaces of the krills 3a, 3b, 3c, and 3d for smooth yarn guidance. Even if the yarn feeder attached to one circular knitting machine has a degree of wear of the rubber ring for each krill, Since it is different, there is a difference in tension when yarns are discharged from the krill of each yarn feeder, which is a major cause of fabric failure.

In addition, in the formation of jacquard patterns, in addition to the accurate supply and interruption of the required color yarn, it should be able to appropriately cope with changes in the feed quantity. Such a jacquard knitting yarn feeder is complicated in structure and precise. Since it must be configured to be expensive, the installation is expensive.

The doctor supplies and clamps at the right time, so that the yarn does not sag or entangled and operates smoothly under constant yarn tension, so that the surface of the knitted fabric can produce even and clear stripes. There was no research and no experiment.

Under the above object, in the present invention, by developing a krill control means using an electromagnet brake, it is possible to partially operate and deactivate only the krill separately from the main body of the yarn feeder with a simple structure, thereby supplying and discontinuing the desired color yarn during banding. It is possible to precisely repeat the high-quality striped fabric without damaging the knitting yarn under a constant tension, and even the complex patterns of the jacquard pattern can be precisely manufactured so that the new operation method with excellent production efficiency and low manufacturing cost is possible. The feeder was developed.

In addition, the switches 11 embedded in the switch supporting members 30a, 30b, and 30c are built in the respective switch cases 32 so that the lint cannot be deposited on their surfaces so that the switches are accurately As a result, the stripe knitting yarn supply device (A) according to the present invention can supply the yarns (Y) accurately, and also, such as the yarns, pastes, waxes and the like suspended in the textile factory Since the flame material does not directly contact the switch 11, it is also safely protected from sparks due to the occasional discharge, thereby preventing a large fire in advance.

The switches 11 are not required to be of special construction and usually limit switches are applied.

And the present invention for supplying striped knitting yarns (A) according to the present invention is sufficient to maintain the guide length of the knitting yarn (Y) under a constant yarn tension in accordance with the length between the non-operating knitting needle of the circular knitting machine when changing the color yarn to supply appropriately according to the pattern The guide member 10 attached to the lower housing 1b is provided with three guide holes 10a, 10b and 10c.

The stripe knitting yarn supply device A according to the present invention having such a structure is operated by the rotation of the driving means operated as in the known manner, and the yarns fed from the bobbin or cylinder of the yarn supply source as shown in FIG. (Y) is guided to the guide hole (13a) of the guide member 13 and contacted the lower surface of the detection rod (7) through the rod catcher 17 to penetrate the lower guide hole (13b) of the guide member (13) It is wound several times around the next krill (3).

After that, the yarn (Y) is passed through the guide hole (12a) of the intermediate guide member 12, and then hooked to the index bar (6) through the guide hole (10a) of the guide member 10 and then again the second guide hole After passing through (10b), and caught by the detection rod (6) again, it is fed to the circular knitting machine while passing through the third guide hole (10c) in turn. Thus, according to the present invention, the stripe knitting yarn supply device (A), the yarn (Y) through the three guide holes (10a) (10b) (10c) of the guide member 10 in sequence to match the striped pattern A sufficient amount of yarn length can be secured so that the yarn (Y) can be properly supplied under tension, and the yarn (Y) can be kept under tension without being stretched or twisted even during feeding and interruption.

Thus, a plurality of stripe knitting yarn supply device (A) of the present invention is operated in accordance with the operation of the circular knitting machine, and when the yarn (Y) is supplied normally, as shown in Figures 7 and 8a In this case, the magnet guide 9a of the krill control means 50 is spaced apart from the switch support member 30a, and the magnet guide 9b is also spaced apart from the switch support members 30b and 30c. Is moved to the "a" position. That is, in this case, the magnets 31b and 31c of the magnet guide 9b do not affect the switch 11.

Therefore, since the clutch 19 installed in the lower housing 1b acting on the magnet guide 9b is not affected by the electromagnet 21, the connection ring rotated by the rotation shaft 14 of the upper housing 1a. In contact with the member 33 is brought into a state of rotating together with the rotation shaft 8 in accordance with the rotation of the connecting ring member 33.

In addition, when the supplied yarn Y is changed according to a predetermined pattern, the magnet guide 9b is moved to the "b" position that engages with the switch supporting member 30b, as shown in Figs. As the magnet 31b of the magnet guide 9b pulls the flow terminal of the switch 11 in the switch supporting member 30b to the fixed terminal, the electromagnet 21 of the krill control means 50 is interconnected and connected thereto. This action causes the clutch 19 to be pulled into the lower housing 1b. Therefore, since the clutch 19 is separated from the connecting ring member 33 which is attached to the rotation shaft 14 of the upper housing 1a, the krill 3 stops rotating. That is, at this time, the magnet guide 9a of the krill control means 50 is held at the same position as in FIG. 8A so that the entire banding yarn feeder A according to the present invention operates, but the krill 3 stops. do. Therefore, it is possible to prevent the damage caused by idling of the krill (3a) (3b) (3c) (3d) seen in the known yarn feeder shown in FIG.

7 and 8C, when the yarn Y being supplied is cut for some reason or the whole circular knitting machine is stopped, the magnet guide 9a is coupled to the switch supporting member 30a to attach the magnet 31a. As a result, the detection rod 7 falls to the downward non-operational position (I), and the magnet guide 9b is also moved to the “c” position that engages the switch support member 30c, thereby providing a magnet as shown in FIG. 8B. The magnet 31c of the guide 9b is connected by pulling the floating terminal of the switch 11 in the switch supporting member 30c to the fixed terminal and the detecting rod 6 connected thereto is moved to the inoperative state (II). . At this time, the magnet guide 9b of the krill control means 50 is coupled to the switch support member 30c immediately and elastically by the elastic member 26 which is fastened to the magnet guide receiving portion 29 to detect the rod 6. The yarn (Y) is quickly discontinued as it moves to an inoperative state. Therefore, there is no phenomenon that the yarn is stretched or wound around other members due to the unnecessary supply of yarn.

In addition, even when the supply amount of various color yarns such as jacquard patterns is to be made irregularly, the ring 5 and the ring support part 4 are mounted on the lower part of the krill 3 so that the yarn Y moves around the ring support part 4. By being caught by the ring (5) which passes through the flange (4a) of the ring support (4) and then further through the guide hole (35a) of the guide member 35, the yarn (Y) to the pattern while maintaining a constant tension state Since the supply and interruption of the yarn (Y) can be made to fit, even a complicated pattern of fabric can be smoothly knitted well.

Stripe knitting yarn supply device (A) according to the present invention is preferably mounted on the circular knitting machine in a zigzag pattern two to the top and bottom to match the color of the stripes, in this case, the yarn (Y) of each krill (3) may be contaminated It takes up little space for installation.

According to the present invention as described above stripe knitting yarn supply apparatus, it is possible to control the supply and interruption of the yarn precisely and quickly by a simple structure, and the yarn feeder that is not supplied when the color of the supplied yarn changes The krill is not operated to prevent the damage of the yarn due to the idling of the krill to evenly knit the fabric, because the yarn is not contaminated during knitting, it is possible to knit the fabric with a clear pattern.

In addition, the apparatus for supplying stripes for knitting according to the present invention is excellent in durability and can be used semi-permanently with almost no failure. In addition, the manufacturing cost can be applied to circular knitting machines in a very practical manner.

In addition, by installing the ring and ring support on the lower part of the krill, even when complex patterns such as jacquard patterns can be adjusted properly under tension, there is no need to install a separate yarn feeder for jacquard patterns. High-quality fabrics can be organized.
