Description

A method and an apparatus for winding elastic thread

The present invention relates to a method for winding the elastic yarn and the spin winding machine, in more detail, in replacing the bobbin and the bobbin, after the initial rotation of the rotating plate 180 degrees does not affect the rotation of the ball bobbin. By falling down at a constant speed in the range to be in close contact with the bobbin, the elastic yarn is prevented from being easily wound around the touch roller due to the decrease in the initial bobbin speed. The present invention relates to a method of spinning and spinning of an elastic yarn to minimize the number of yarns.

In general, a device for winding an elastic yarn produced in a yarn shape alternately in the gongbobin is known and in use, which is disclosed in Korean Patent Laid-Open Publication No. 95-11301 (elastic yarn winding method and spin wound machine; When referred to as a conventional invention) as an example.

Fig. 5 shows a conventional spinning winding machine, in which yarns of elastic yarns are wound sequentially by two or more bobbin holders to switch the elastic yarns Y running from the bobbins B1 to the bobbins B2. In the winding machine, a thread-guiding device 102 is installed in which the elastic yarn moving to the manbobin B1 in the standby position is wound up to the upstream elastic yarn of the bobbin by way of the bobbin in the winding position. It features.

Therefore, Figure 6 is a process diagram showing the winding method according to the spin-winder configured as described above, the winding of the elastic yarn is completed in the bobbin (B1) is in close contact with the touch roller 101, the Gongbobin (B2) is located at the bottom (See FIG. 6A);

The turret plate 100 located in the center is rotated forward to move the manbobin B1 to one side, so that the elastic yarn is in close contact with the outer diameter of the touch roller 101 and stretched along the manbobin B1 (see FIG. 6B). and;

The turret plate 100 is continuously rotated forward so that the mann bobbin B1 is excessively positioned in a vertical line, and the elastic yarn Y is stretched while being in close contact with the outer diameter of the touch roller 101. A process in which the touch roller 101 is lowered while a part of the elastic yarn Y is in close contact with the outer diameter (see FIG. 6C);

The turret plate 100 is continuously rotated forward so that the bobbins B1 and the bobbins B2 are positioned on the horizontal line, and the elastic yarn Y is stretched while being in close contact with the outer diameter of the touch roller 101. Simultaneously rotating the guide bar of the guiding device 102 and winding the elastic yarn Y in the bobbin B2 and cutting the elastic yarn (see FIG. 6D);

On the contrary, the process of winding the elastic yarn (Y) on the ball bobbin (B2) by decelerating the turret plate (100) and decelerating the ball bobbin (B2) (see FIG. 6E);

Finally, through the process (see Fig. 6f) in close contact with the bobbin (B2) to the touch roller 101 of the lowered position to replace the bobbin (B1) and the bobbin (B2).

However, in replacing the bobbin (B1) and the bobbin (B2) by the above apparatus and method, the deceleration ball bobbin (B2) in the winding process (see Fig. 6f) of the bobbin (B2) is a touch roller ( Due to the impact and friction generated at the moment in close contact with the 101, the speed of the gongbobin (B2) is lowered and the elastic yarn (Y) is easily wound around the touch roller 101, the elastic yarn (Y) is broken I had.

In addition, the replacement of the manbobin (B1) and Gongbobin (B2) has a problem that takes a lot of replacement time, because the travel stroke is longer as the turret plate repeats the forward and reverse rotation.

In addition, as the gongbobin (B2) and the manbobin (B1) must satisfy the condition (see Fig. 6d) that must be stopped at the intermediate position for real guidance, there is also a problem to provide a separate stop device for the turret. there was.

Accordingly, the present invention was invented to solve the above problems, and in replacing the bobbin and the bobbin, the touch roller after the initial rotation of the rotating plate 180 degrees in a range that does not affect the rotation of the bobbin. The object of the present invention is to provide a method of winding a yarn of elastic yarn and a yarn winding machine by lowering the speed so as to be in close contact with the bobbin, thereby preventing the elastic yarn from being easily broken by preventing the elastic yarn from being wound by the touch roller.

In addition, as the touch roller is gradually lowered vertically and closely attached to the bobbin, there is also an object of preventing the rotation speed of the bobbin from falling off at the beginning of winding.

In addition, when the replacement of the manbobin and gongbobin by rotating the rotating plate by 180 degrees so as to change only the operating position and the standby position by reducing the movement stroke, there is also the purpose of minimizing the replacement time.

In addition, it is also possible to reduce the unit cost of the apparatus by simplifying the forward and reverse rotation apparatus for performing the thread hook.

On the other hand, by using a rotating arm including a cylinder when the elastic yarn is switched to the gongbin, there is also an object to increase the outer diameter of the gongbin and the contact angle of the elastic yarn.

In order to achieve the above object, the present invention, in the spin winding machine to replace the manbobin and gongbobin winding the elastic yarn, the waiting process for exchanging the manbobin and gongbobin up and down, and the lifting unit is fixed to the upper position In the state that the rotating plate rotates by 180 degrees, the position of the manbobin and the ball bobbin is replaced, and the contact angle of the ball bobbin is caused by the elastic arm being rotated at a certain angle around the upper end to the outer diameter of the ball bobbin. Radiation winding method characterized in that the bobbin bobbin winding process that the elastic yarn supplied to the manbobin is broken under the condition that the Tao Gongbin bin can hold the elastic yarn sufficiently and exchanges the bobbin and the bobbin through the rotating arm return process and; In addition, both sides are equipped with a bobbin holder is equipped with a rotary plate is equipped with a drive motor rotated by 180 degrees, repeating the descending and lifting every 180 degrees of rotation of the rotating plate, and has a touch roller and a main roller to guide the supply of elastic yarn It features a spin winding unit consisting of a lifting unit, and a thread switching unit consisting of a rotary arm having a guide member and a reverse rotation device after completing one stroke of thread hook switching every 180 degrees of rotation of the rotating plate.
