Description

TWISTING MACHINE FOR SILK YARN}

In order to make a yarn with sufficient strength, it is necessary to twist two or more threads, and to use a twisted yarn with sufficient strength in order to make a strong cloth and to have a solid appearance. .

Up to now, silk thread has been wound into the threading thread at the top of the auto-irradiator. Threads from 7-8 strands or more of silkworm cocoons are twisted, collected into one thread, and then threaded through one hole. do.

The mentioned mechanism is unable to twist the thread firmly and cannot control the twisting of the thread. Therefore, it is difficult to produce a variety of fabrics that are tough and difficult, and it is difficult to produce a considerable high quality silk suitable for knitting. In addition, due to mechanical limitations, there is a limit to the productivity improvement in twisting and then gathering several strands of thread.

Advantages and objects of the present invention are as follows.

-In order to reduce power consumption, we want to manufacture a compact machine.

-In order to improve productivity, the number of rotations of mechanical equipment will be increased.

-By controlling the number of twists in the thread, the strength and appearance of the twisted thread is increased significantly for weaving or knitting various, durable fabrics.

The invention is explained in detail with reference to the accompanying drawings.

In order to achieve the above object, it is essential to rotate the body (body) equipped with the noses as fast as possible.

In order to increase the number of rotations, a set of bearing sets, a new invention that is coupled to the rotating shaft of the body and the rotating shaft of the motor, is devised.

Furthermore, a specially designed realization mechanism (FIG. 1) devises a silk thread over the specially invented nose that causes the silk to be unwound from the nose when the body and the coons rotate about the axis of rotation.

The newly invented Coon is made of light plastic or wood. Surface A and surface B are designed to be slightly inclined. Surface A and vertical line L are made slightly inclined. The P and Q planes are manufactured to be inclined rather than straight. The layer of thread produced (TL) also forms a certain curve (figure 5) and the strands are wound at intervals of Pi. The appearance and shape of the coon is designed so that the thread is wound on the surface of the coon below the A surface without deviating in the direction of the arrow from the B surface.

The thread released from the cocoon moves in the direction of the arrow while the cylindrical rod fixed to the disk connected to the power transmission belt is driven by the electric motor.

The hook <5> connected to the spring pulls the silk below the dotted line. The silk thread passes through a thread guide 6 consisting of two small smooth plates under the proper pressure by a spring.

The thread winding tension changes as the thread moves in the direction of the arrow E or F. As the thread moves from C to D, which coincides with the direction of arrow F, the thread winding tension decreases, and as the thread moves from D to C, which coincides with the direction of arrow E, the thread winding tension increases.

Therefore, the moving speed of the yarn increases while the rod &lt; 3 &gt; rotates in the direction of arrow F and decreases in moving in the direction of arrow E. FIG.

As the thread moves slower near C and faster near D, the layer of thread gets thicker and winds up closer to C.

Due to the above, the tension of the silk is adjusted. The tension is periodically changed, and the silk is moved in the direction of the arrow and is wound on the surface of the coon while forming a layer of the yarn of <figure 5>.

The layer of silk wound around the coon formed by the above process can be smoothly released without being entangled when rotating about the coon and the body.

Due to the characteristics of the thread unwinding of the thread layer described above, the thread passes through the guides <11> and pulls from the coon without friction and wear as much as possible to prevent breakage of the thread caused by friction between the thread and the thread layer. <Figure 5>

As the yarn moves in the direction of the arrow E or F, it is possible to make the shape of the seal layer mentioned above, which has the characteristic of unwinding the thread by varying the speed of winding the yarn in the nose.

By applying electronic circuits, the rotational speed of the electric motors can be adjusted periodically to change the winding speed of the thread.

On the other hand, the movement speed of the rod <3> varies depending on the direction of the arrow E or F by applying an elliptical cam, a spring, and a moving rod to form a seal layer of the yarn having the above-mentioned efficient loosening property. It may be possible to configure a moving device of a thread.

By varying the gap between the two strands wound around the nose (Fig. 2), it is difficult to adjust the speed ratio between the axis (1) and the disc (2) if it is necessary to form a thread layer with different loosening characteristics. Can be achieved.

Adjust the speed ratio mentioned above, the tension of the thread in the guide, or the cam movement, the moving rod, and the spring so that the thread wound over the nose does not get tangled and the thread breaks due to the friction between the loose thread and the thread layer. As a result, the shape of the seal layer wound on the surface of the coon may be changed.

Coons and body wound with silk are driven by an electric motor to rotate at high speed about the axis. Power is transmitted to the belt. 〈Figure 3〉

Such a device consists of the following components.

-The body on which the coons are mounted. <7>-The shaft connected to the body <8>.

-Bearing support <13>-bearing set attached to the shaft <9>

-Guide that silk thread passes through from Coon to fuller <11>

A guide made of two small, smooth plastic or rubber plates, with a suitable pressure suspended by a spring

-Twisted silk winding device.

Two coons are mounted on the body (Figure 3). A body can be made with three to five coons.

In order to significantly increase the production of the yarn in the twisting machine, it is necessary to rotate the shaft connected to the body at a higher speed and increase the winding speed of the twisted yarn to operate the device 10 at high speed with high productivity.

The bearing set, coupled to shaft 8, is designed to allow the shaft to rotate faster.

The newly invented bearing set is made of an elastic rubber sheet sandwiched between one bearing with a large inner diameter, the other bearing with a small inner diameter, and two different bearings. The bearing set is fixed to the bearing support and the shaft <8> is coupled to the bearing set. The axis 8 between the two bearing rings moves with the belt 14.

The power of the electric motor is transmitted to the shaft by a belt.

The use of bearing rings offers the following advantages:

-Reduces friction and allows the shaft to rotate at higher speeds than conventionally used bearings. Therefore, the amount of production of the yarn is increased to a considerable extent in the knitting of the yarn.

-Reduce power consumption.

-It is easy to manufacture the shaft because it does not have to focus on the surface machining and processing precision.

-Increase the number of revolutions of the motor by coupling the bearing set to the shaft of the motor.

The thread released from the coon passes through a guide (11) made of a ring of small wires, and then through a guide (12) consisting of two small plates under moderate pressure with a spring. The guide 12 is designed to adjust the tension of the seal by adjusting the pressure of the spring when the seal is released from the nose.

The twisted thread winding device <10> is manufactured in a cylindrical shape. The device can be driven by electric motors or manually.

While the silk is released from the coon, the coiled coon gradually becomes lighter. Therefore, as the body with the coons mounted becomes lighter gradually, the body rotates about the axis at a higher speed. In order to maintain the degree of twist <coin per inch>, it is necessary to change the winding speed of the device <10> according to the increase and decrease of the speed at which the body and the coons rotate.

Best way to carry out the invention.

〈Feeling Mechanism〉

-Install the coon on the shaft of the machine and pass the thread through the guide <5>, guide <6> and rod <3>.

-Wrap the silk thread around the nose with your hand and move the shaft with the coon by the electric motor.

-The pressure of the spring of the guide <6> is adjusted so that the proper tension of the seal is kept constant.

By adjusting the spring of the guide <5> and the guide <6>, it is necessary to pull the silk below the dotted line to adjust the thread to have a constant tension.

-The mechanism will stop if the thread breaks due to the weakness and tension, due to its low node and strength.

-Stop the mechanism, and then the silk is rolled over the nose again.

The winding mechanism is activated until the weight of the thread wound around the nose reaches a certain weight.

〈Threading Mechanism, Stringing Machine〉

-Two or more coons that reach a certain weight are mounted on the body.

-The thread released from the coon passes through the guide (11) and guide (12).

-Twist the silk thread by hand and wrap it around the device (10).

-Coon and body are rotated at high speed by electric motor and device <10> is operated manually.

-It is necessary to change the winding speed in the device <10> to keep the twisting degree constant. In addition, it is necessary to pay close attention to the degree of twisting with eyes in order to keep the degree of twisting constant.

Furthermore, it is necessary to adjust the pressure of the guide (12) in order to keep the twisting degree constant.

The beneficial effects are summarized below.

-Improves productivity by rotating the shaft connected to the body at a higher speed.

The amount of fired is greatly increased.
