DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil applying device for applying an oil to running yarn.

[0002]

2. Description of the Related Art Generally, when producing synthetic fibers such as polyester and polyamide, an oil agent is applied to a running yarn to improve the bunching, smoothness and antistatic properties of the yarn. In a manufacturing process such as drawing, it is attempted to improve the spinning property. It is well known that an oil agent is applied in the post-processing step of the yarn such as weaving, knitting, and dyeing in order to improve the quality of the product and to spin the occurrence of process trouble.

[0003] As a method of applying an oil agent to a running yarn, in recent years, with the need to improve productivity, a high-speed yarn-making technique has been developed, and a guide type oil agent applying device has been used. As such a guide type oil applying device, for example, Japanese Utility Model Laid-Open No. 1-119067 discloses a method in which a fixed amount of oil is supplied to the oil supply guide while the yarn is brought into contact with the guide, thereby running at high speed. An apparatus for applying an oil agent to a yarn has been proposed.

[0004] However, a problem in an apparatus for supplying a fixed amount of oil to the guide while the yarn is brought into contact with the oil supply guide and thereby applying the oil to the yarn running at high speed is a problem. The adhesion of the oil agent to the yarn is determined by the amount of the yarn taken out when the oil comes into contact with the yarn.Therefore, the amount of the oil agent measured is Even if used, the fineness of the running yarn, the number of single yarns, etc. are greatly affected, for example,
If the fineness is small and the number of single yarns is small, the metered oil will not be able to adhere to the yarn and will cause adhesion spots, which will adversely affect the bunching, smoothness, and antistatic properties of the yarn, preventing stable yarn production. In addition, there is a problem that the quality of the obtained yarn is deteriorated.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide an oil applying apparatus which can supply oil without being greatly affected by the number of single yarns of the running yarn.

[0006]

According to the present invention, there is provided an oil supply device having an oil supply unit for applying a fixed amount of oil supply to running yarns, wherein the oil supply discharged by electrifying the oil supply unit is provided. The present invention provides an oil applying device characterized by spraying.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, an oil supply unit for spraying an oil agent discharged by electrifying the oil supply unit is used instead of an oil supply guide in contact with the running yarn. The oil agent discharged by electrification can be sprayed with the particle diameter and the interval of the droplets uniform.Also, since the oil agent is applied in a non-contact manner, it is not greatly affected by the convergence state of the yarn or the number of single yarns, Forcibly dispensed oil agent can be applied. Therefore, unlike the conventional lubrication guide, lubrication can be performed without being greatly affected by the fineness of the running yarn and the number of single yarns.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of the present invention.

In FIG. 1, Y is a running yarn, 1 is an oil supply section for applying a constant amount of supplied oil to the running yarn (Y), and 2 is a yarn path of the yarn (Y) at a predetermined position. A guide for maintaining the regulation, 3 is a device for electrifying the oil supply unit, and 4 is a hose for supplying an oil agent to the oil supply unit.

On the outer peripheral surface of the guide 2, a V-shaped or U-shaped focusing groove is formed in order to regulate the yarn path of the traveling yarn (Y) at a fixed position and maintain this state. ing.
For this reason, when the running yarn (Y) is pressed against and contacts the focusing groove of the guide 2, it moves to the bottom of the V-shaped or U-shaped focusing groove. As a result, the yarn path of the traveling yarn (Y) is regulated at this fixed position without moving from the bottom of the focusing groove, and the yarn runs stably while maintaining this state.

The oil supply unit 1 is mounted at a position where the oil can be sprayed toward the guide 2, and the oil supply unit 1 is electrified and forcibly supplies a constant amount to the yarn by making the particle diameter and interval of the sprayed oil uniform. The applied oil agent can be applied.

The principle of an ink jet printer is used as a method for making the particle size and interval of the sprayed oil agent uniform.
In FIG. 1, the oil agent supplied to the oil supply unit 3 by a hose for supplying the oil agent to the oil supply unit passes through a vibrating nozzle by a piezoelectric element installed in the oil supply unit, so that the oil agent also vibrates. Due to this vibration effect, the ejected oil is continuously separated into uniform particles having a constant size and flying at a constant speed.

Examples 1 to 3 Next, the results of experiments conducted using the apparatus of the example shown in FIG. 1 will be described in detail with reference to Table 1.

[0014]

[Table 1]

In Table 1, Examples 1, 2 and 3 show that when melt-spinning a polyester chip at a spinning speed of 3000 m / min, the oil supply device illustrated in FIG. This is an experimental example to which the present invention was applied, in which the discharge port diameter of the oil supply section for injecting the oil agent was 40 μm, the electrification applied to the oil supply section was 30 kHz, and the distance between the oil supply section for injection and the yarn was 20 mm.

Comparative Examples 1, 2, and 3 use an oil applying device using the conventional contact-type refueling guide 5 illustrated in FIGS.

The amount of the oil agent adhered is a percentage (%) of the weight of the oil agent adhered to the total weight of the fibers, based on the amount of methanol extracted according to JIS. Adhesion fluctuation range is
The amount of oil agent adhesion was measured five times, and the variation was shown.

As is apparent from Table 1, the amount of the oil agent adhered is
In the lubricating apparatus of the present invention, the amount of oil agent adhesion hardly fluctuates, and the variation in the lengthwise direction indicates a small variation in the amount of adhesion. It can be seen that the sticking variation in the direction is large. That is, the excellent effect of the present invention as a lubricating oil applying device is proved without being largely affected by the fineness of the running yarn and the number of single yarns.

[0019]

As described above, according to the present invention,
By using an oil applying device characterized by spraying an oil discharged by electrifying the oil supply section, the oil supply is not greatly affected by the running yarn fineness and the number of single yarns as in a conventional oil supply guide. Can realize what is possible,
This has a remarkable effect of being able to provide an oil application device without oil agent adhesion spots.
