In order to manufacture textiles such as garments and curtains, yarns such as low shrinkage twisted yarn and high strength nylon yarn are coated with polymers having various functions such as far-infrared radiation effect, direction, deodorization and flame retardant. It is well known that coated yarns are used for weaving.

There are two methods for producing a polyester yarn, such as a direct spinning drawing process (DSD; Direct Spinning Drawing) or a transverse drawing process (W / D; Warp Drawer-transverse drawing of undrawn yarn).

The DSD method is a process of direct spinning which is connected to spinning and stretching, and is a method of spinning, stretching, and relaxing the unstretched yarn spun under the confinement of the spinning unit through a roller stretching and relaxation process to manufacture yarn. This is connected to one processor.

In addition, the W / D method is known as a method of manufacturing a yarn after the unstretched yarn manufacturing process and the stretched yarn manufacturing process are separated, and after the unstretched yarn is manufactured, the yarn is stretched and relaxed in a transverse stretching machine.

The polyester yarn may be manufactured by selecting from existing methods, and the polyester yarn manufactured as described above may be coated to complete the yarn for being woven into the product.

Winding the coated yarn at gives the finished product.

However, it is well known that the problem of poor workability is always pointed out due to the inability to actively adjust the tension provided to the yarn during the spinning operation of the coated yarn.

In addition, when the coating process is cooled and wound around the bobbin of the winding part, after a considerable amount of yarn is wound around the roller of the winding part, the roller is wound in a separate device and quantified. There is a problem in that the complexity of having to go through the process of being sequentially wound in a plurality of rollers in a small amount in a predetermined state, and a phenomenon such as yarn breaking in this process may occur.

Therefore, the present invention has been made to solve the above problems,

It is an object of the present invention to provide an apparatus for automatically quantifying a small amount of the finished yarn obtained after coating a flame-retardant PVC on its outer circumferential surface using a polyester yarn.

Since the coating apparatus 100 does not belong to the scope of rights in the present invention, a detailed description thereof will be omitted, and a known means may be coated by receiving a plurality of yarns 10 at a time. Can be used.

The cooling device 200 is a configuration in which a plurality of yarns 10 are coated by a coating device 100 at a time and cooled by a water cooling method of the coated yarns 20 discharged at a time. Flow to the storage tank 210 to be cooled.

The tension control unit 300 is a means for providing a tension force by the appropriate tension to the coating yarn 20 is transferred to the cooled state through the cooling device (200).

The reason for providing tension to the coated yarn 20 as described above is to maximize the impregnation efficiency by proper coating between the PVC melt coated on the outer surface and the polyester yarn 10, as well as the coated yarn 20 This is to prevent the phenomenon of breaking during winding in the subsequent process by making the thickness of the constant.

Such tension control unit 300 is sequentially configured by the first tension control unit 310 and the second tension control unit 320 as shown in the figure.

The first tension control unit 310 is arranged so that a plurality of rollers 311 are spaced apart and spaced apart from each other, and the rollers 311 are guided by alternating contact with the coating yarn 20 in sequence. Thus, a uniform rotational force is provided to the coated yarn 20 by the separation distance between the rollers 311 and the rotational force of the rollers 311 while passing through the rollers 311 so that the PVC melt coated on the outer surface is even. It is distributedly coated and allows to provide tension.

The second tension control unit 320 is configured to guide the respective coated yarns 20 passing through the first tension control unit 310 and guided toward the winding bobbin unit 400 which will be described later. .

As shown in the drawing, the second tension adjusting part 320 fixes a plurality of fixing parts 330 vertically fixed from the ground to guide each coated yarn, and an upper end of each fixing part 330. A horizontal bar 331 extending to one side is formed, and the upper adjustment roller 332 is axially fixed to guide the coated yarn 20 on the upper surface side of the horizontal bar 331.

The fixing part 330 configured as described above should be provided as many as the number of coated yarns 20 supplied.

On the other hand, while supporting the coating yarn 20, which is supported and flowed by the upper adjustment roller 332, at the same time freely up and down to enable an active response in accordance with the winding speed in the winding bobbin 400 to be described later The lower adjustment roller 333, which is arranged to be movable, is arranged to be arranged on the end side of the free pivoting arm 334, which is rotatably fixed to the center point of the fixing part 330.

In addition, the plurality of guide grooves 332a and 333a are formed at equal intervals to the outer circumferential surface of the upper adjustment roller 332 and the lower adjustment roller 333, and then the coated yarn 20 passes through the tension adjusting part 300. The upper and lower adjustment rollers 332 and 333 are supplied to the winding bobbin unit 400 through the upper and lower adjustment rollers 332 and 333 while being wound in the guide grooves 332a and 333a formed on the outer circumferential surface thereof.

Therefore, as shown in the drawing, the plurality of coated yarns 20 coated and supplied from the coating apparatus 100 are guide grooves of the upper adjustment roller 332 built on the horizontal bar 331 on one side of the fixing part 330, respectively. After winding along 332a), a plurality of lower adjustment rollers 333 arranged on the free rotating arm 334, one side of which is freely rotatable, is provided on the fixing bracket 335 positioned below the plurality of windings. After winding several times along the guide groove 333a, it is supplied to the winding bobbin unit 400 to be described later.

Here, as described above, the lower adjustment roller 333 provided in each fixing part 330 is coated according to the moving speed of the coated yarn 20 and the coated yarn 20 wound in the winding bobbin portion 400. The feed speed of the yarn 20 is variable, corresponding to the variable speed and configured to enable the vertical flow of the free rotating arm 334, for example, the coated yarn 20 in the winding bobbin portion 400 to be described later As winding is wound on the winding bobbin 400, the winding outer diameter of the bobbin winding the coated yarn 20 is gradually increased, so that the feed rate of the coated yarn 20 must be gradually increased. In response to this, the tension to pull the coated yarn 20 is gradually increased, so that the lower adjustment roller 333 supporting the coated yarn 20 can be freely rotated up and down by the above configuration. To increase the pulling force of the coated yarn 20 When the lower adjustment roller 333 is rotated upward and the pulling force of the coating yarn 20 decreases, that is, when the first coating yarn 20 is wound around the winding bobbin 400, the lower adjustment is performed.
