Description

Spandex yarn feeding method of double winder and apparatus therefor.

The present invention relates to a spandex yarn feeding method and a device of the double winder, and more particularly, to form a feeding portion for supplying the spandex yarn integrally with the winding portion and at the same time improve the shape of the feeding roller to simplify the device and stable feeding This is to achieve the improvement of the quality and productivity of the winding products.

In general, the winder is wound in the bobbin at a certain weight and shape of the yarn that needs to be twisted in the entire process of the twisting process.

In recent years, however, the use of double winders is being increased to allow two or more different types of yarns to be simultaneously wound so that the yarns can be twisted simultaneously in order to simultaneously yarn yarns of different properties to meet the demand of various textile papers.

In order to give elasticity to the yarn, one of the winding yarns is often made of a spandex yarn made of rubber, and for this purpose, a spandex yarn feeding unit is required for a double winder.

The spandex yarn feeding part 1 of the double winder is configured with a winding part 2 and a tension part 3 constituting the double winder, as shown in FIG. 1,

The feeding part 1 is composed of a drive motor 10, the feeding roller 11, the spandex yarn 13 wound on the bobbin 12, this feeding part 1 is one side of the lower end of the winding part (2) Is formed.

The feeding part 1 transmits the rotational force of the driving motor 10 to the feeding roller 11 fastened by the belt 14, and the feeding roller 11 rotates the spandex savo bobbin 12 which is connected. The spandex yarn 13 is transferred to the winding section 2 via the tension section 3.

The tension unit 3 is provided with various tensioning devices including the tension roller 15 so that the uniform winding tension can be applied to the spandex yarn 13,

The spandex yarn 13 which has passed through the feeding part 1 and the tension part 3 as described above is wound up in a state of incorporation into the cylinder 17 which is rotated by the winding drum 16.

However, the spandex yarn feeding structure of the configuration and operation as described above has the following problems.

First, a feeding distance due to separation of the feeding unit 1 and the winding unit 2 is formed long.

As described above, when the feeding part 1 is located at the lower end of the winding part 2 and the feeding distance is long, considering that the material of the spandex yarn 13 is a rubber material, the longer the feeding distance, the more the spandex by working time and the surrounding environment. There is a problem that the uniform tension control is quite difficult because the tension deviation acting on the yarn 13 is increased.

In addition, the feeding unit 1 as described above is provided on one side of the lower side of the double winder and is not exposed to the outside due to other components, so that it is alienated from the working field of the worker, and there is a problem in lack of workability during maritime and cutting.

In addition, the feeding roller (11) for driving the connection with the spandex yarn 13 to perform the maritime operation, as shown in Fig. 2 is a fixed hole (19) for coupling with the rotating shaft in its inner diameter (d) The cylindrical surface having a surface treatment is made to prevent cutting and damage of the spandex yarn (13).

However, the feeding roller 11 is most flat on the surface of the spandex yarn 13 due to the frictional pressure during the contact driving of the spandex yarn 13 since the contact surface t of the wound spandex yarn 13 is flat. A bend is formed inwardly from, which causes a reduction in the contact area with the feeding roller 11.

As described above, when the contact area between the feeding roller 11 and the spandex yarn 13 decreases, slippage occurs between each other, resulting in unstable plywood, and in severe cases, a problem of cutting the spandex yarn 13 may occur. there was.

Since the double winder formed as described above is equipped with a drive motor for feeding and a drive motor for winding at the same time, there was also a problem of lack of economy due to duplication of components and an increase in production cost and power consumption.

Accordingly, in the present invention, the feeding part required for supplying the spandex company is integrally formed at the upper end where the winding part is located to minimize the feeding distance, and the curved part is formed on the outer circumference of the feeding roller to act as a friction force. The purpose of the present invention is to allow smooth bending and feeding by preventing slip phenomenon by making the curved portion of the spandex yarn and the curved portion of the feeding roller coincide with each other.
