[0014]

Conventionally, in the case of twisted glass fiber, a vertical ring or a conical ring including a ring height and a ring diameter is selected according to the type of glass fiber and spinning speed. However, the conventionally used sintered doubler ring or vertical ring has a total height H of the ring body of 6.3 mm to 38.1 mm, so that the height of the nylon traveler applied to these rings is high. And only a heavy traveler with a weight of 30 mg or more could be used. When trying to use a light traveler with a traveler weight of 30 mg or less,
The thickness of the traveler or the width of the traveler must be reduced, and the strength of the traveler is reduced, so that it cannot be used.

For this reason, the conventional 3,000 r. p. m ~
6,000r. p. m and 6,000 rpm. p. When it is increased to m or more, the spinning tension increases, the contact resistance between the glass fiber and the traveler increases, the most unfavorable yarn fluff in the glass fiber increases, and the quality of the yarn is greatly reduced. There was a point.

Furthermore, since the traveling surface of the traveler provided on the inner peripheral surface of the ring main body is formed by a plane parallel to the axis of the ring main body, when the spinning tension is increased as described above, the traveler is moved by the yarn. It is pulled upward, and the lower contact portion of the traveler makes strong contact with the lower end of the ring body, causing local wear at the lower contact portion of the traveler. The lower portion of the traveler bites into the lower surface of the ring body, and the traveler In addition, the traveling posture of the vehicle becomes unstable, and the wear of the traveler progresses rapidly, resulting in a problem that the life of the traveler is significantly shortened, the traveler is scattered, and yarn breakage occurs.

When the conventional conical ring is used for twisting glass fibers, the traveling surface of the traveler has an inclination angle x of usually 10 ° to 15 ° with respect to the axis of the ring main body, and the upper part of the ring and the traveler Since the ratio to the running surface is as small as 1: 2, the traveler comes into three-point contact with the upper end of the upper surface of the ring, the traveler running surface and the lower surface of the ring, and the running posture of the traveler is stabilized, but the flexibility is impaired and the spinning tension is reduced. Fluctuations, the spindle rotation speed was 6,000 rpm. p. m
When raised above, there is a problem that the contact resistance between the glass fiber and the traveler increases, the fuzziness increases, and the quality of the yarn is significantly reduced.

In addition, since the inclination angle x is as large as 10 ° to 15 °, the traveler is strongly pushed down on the traveling surface of the traveler by centrifugal force, and the contact pressure of the contact portion between the lower surface of the ring and the lower portion of the traveler is reduced. Although smaller, the traveler is strongly pressed against the upper surface of the ring, and the contact pressure between the upper end of the upper surface of the ring and the head of the traveler increases, causing localized wear at the contact between the upper surface of the traveler and the upper surface of the ring. However, there is a problem that the wear of the traveler progresses rapidly and the life of the traveler is significantly shortened.

The present invention has been made in order to solve the above-mentioned problems. In a vertical ring, the height of the ring is reduced to 4.2 mm to 5.4 mm, and the traveling surface of the traveler is 2 ° to 2 °. By inclining outward and downward with an inclination angle of 4 °, the weight of the traveler to be used is reduced to less than 30 mg, and by imparting a certain flexibility to the traveler, it absorbs the fluctuation of the tension applied to the traveler, thereby spinning. The tension can be lowered to allow the yarn to be softly wound on the bobbin, and the spindle speed is 6,000 rpm. p.
m, even at high-speed spinning of m or more, it performs twisting of good-quality yarn with less fluff, and at the same time, reduces local wear at the contact portion with the lower ring lower surface of the traveler,
By extending the life of the traveler and improving productivity, and by preventing the so-called trapping phenomenon in which the yarn is caught between the upper surface of the ring body and the head of the traveler, the yarn fuzz and the damage to the yarn are reduced. It is an object to improve yarn quality.

[0020]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and a spinning ring is a vertical ring having a traveler running surface for guiding the traveler on an inner peripheral surface thereof. It comprises a main body and a flange having a fitting portion attached to a ring holder or a ring rail on the outer peripheral surface of the ring main body.

The ring body has a total height H of 4.2 mm or more.
5.4 mm, a thread flank in which the inner peripheral surface is inclined upward and outward with an inclination angle α of 25 ° to 35 ° at the upper part, and a thread flank of 2 ° to 4 ° continuously below the thread flank. And a traveler running surface inclined downward and outward with an inclination angle β.

On the outer peripheral surface of the ring main body, 8 ° to 1
An upper guide surface for guiding the upper leg portion of the traveler inclined upward and outward at an inclination angle of 2 °, and a lower guide surface for guiding the lower leg portion of the traveler formed at the lower part in parallel with the axis of the ring main body. Have.

The thread relief surface provided on the inner peripheral surface and the upper guide surface provided on the upper surface of the outer peripheral surface are connected by a ring upper surface formed by a flat surface, and are provided below the traveler traveling surface and the outer peripheral surface. The lower guide surfaces are connected by a ring lower surface formed by a single or a plurality of arc surfaces or flat surfaces.

The flange portion has an upper surface formed by a flat surface, a flat portion parallel to the upper surface, and an inclined portion inclined downward and outward which constitutes a reinforcing portion that projects downward from an outer peripheral portion continuously with the flat portion. And a lower surface formed by the portion.

On the outer peripheral surface of the flange portion, there is provided a fitting portion with a ring holder comprising a concave groove provided over the entire circumference and an oil guiding thread groove provided at the bottom of the concave groove so as to communicate over the entire circumference. Have.

The upper and lower flat surfaces of the flange are smoothly connected to an upper guide surface for guiding the upper leg of the traveler of the ring body and a lower guide surface for guiding the lower leg of the traveler, respectively. Make up the ring.

In the spinning ring constructed as described above, the traveling surface of the traveler has a straight line or a radius R of at least 80 mm, preferably 80 mm to 150 mm.
It is also possible to configure with a curve having

The height h ₁ of the thread flank is 0.7 m.
m~1.2mm, height h ₂ of the traveler running surface is 3.1m
has M～4.5Mm, and the ratio h ₁ between the height h ₂ of height h ₁ and the traveler running surface of the yarn flank: h ₂ is 1: 3 to 1:
5 may be provided.

The height h ₃ of the upper guide surface for guiding the upper leg of the traveler is． of the total height H of the ring body.
3-1 / 2.5 has a height of lower guide surface for guiding the lower leg portion of the traveler h ₄ is 1 / 3-1 of the total height H of the ring body
/3.5 is also possible.

In the above configuration, the total height H of the ring body is set to 4.2 mm to 5.4 mm, but is set to 4.6 mm to 5.0 mm.
mm is preferable, and when it is less than 4.2 mm, the weight of the traveler to be used becomes unnecessarily light, the spinning tension becomes too low, and when the spindle rotation speed is increased, the ballooning of the yarn becomes overballooning. If it exceeds 5.4 mm, the weight of the traveler to be used becomes heavy and the spinning tension becomes too high, and when the spindle speed is increased, the yarn is stretched and the yarn breaks. Or the contact resistance between the traveler and the yarn increases, causing yarn fluff.In addition, the winding tension on the bobbin increases, causing damage to the yarn wound on the bobbin and greatly improving the quality of the yarn. However, there is a problem that it decreases.

Further, the inclination angle α of the yarn flank is 25 ° to 35 °.
°, but preferably 28 ° to 32 °, and 25 °
If it is less than °, the so-called trapping phenomenon occurs in which the yarn is caught between the yarn flank and the traveler, increasing the yarn fluff or causing yarn breakage, greatly reducing yarn quality and reducing productivity. When the angle is lower than 35 °, the occurrence of trapping phenomenon is reduced, but the flat portion on the ring upper surface is reduced or the flat portion cannot be provided on the ring upper surface. Contact with the head becomes point contact, local wear occurs at the contact part of the traveler's head with the ring upper surface, shortening the life of the traveler, causing abnormal running of the traveler, and increasing the spinning tension. As a result, there is a problem that the contact resistance between the yarn and the traveler increases, and the yarn fluff increases.

Further, the inclination angle β of the traveling surface of the traveler is 2 °.
However, if the spindle rotation speed is increased, the traveler does not sufficiently sink along the traveling surface of the traveler, and local wear occurs at a contact portion with the lower surface of the lower ring of the traveler when the spindle rotation speed is increased. As the life of the traveler is shortened, the traveling of the traveler becomes abnormal, the spinning tension increases, the contact resistance between the yarn and the traveler increases, and the yarn fluff increases. When the rotation speed is increased, the sinking of the traveler increases, and the contact resistance between the lower portion of the traveler and the lower surface of the ring decreases, but the contact resistance between the upper surface of the traveler and the upper surface of the ring increases,
There is a problem that local wear occurs at the contact portion of the traveler, shortening the life of the traveler, causing an abnormality in the traveling of the traveler, increasing the spinning tension, and increasing the yarn fluff.

In addition, the inclination angle θ of the upper guide surface provided on the outer peripheral surface of the ring main body is set to 8 ° to 12 °, but if it is less than 8 °, the engagement between the upper guide surface and the upper leg of the traveler is shallow. When the spindle rotation speed is increased and the spinning tension applied to the traveler increases, the upper leg of the traveler can easily come off the upper guide surface of the ring, causing thread breakage. When the spindle rotation speed is increased and the spinning tension applied to the traveler increases, the sinking of the traveler increases, the contact resistance with the upper ring of the traveler increases, and the contact part of the traveler becomes localized. There is a problem that wear occurs, the life of the traveler is shortened, the traveling of the traveler is abnormal, and the fluff is increased.

[0053]

The spinning ring of the present invention has a structure in which the height of the ring is as low as 4.2 mm to 5.4 mm and the traveling surface of the traveler is inclined at 2 ° to 4 °. In addition, since the weight of the traveler can be reduced, and a certain degree of flexibility can be given to the traveler, the fluctuation of the tension applied to the traveler can be absorbed. p. m and higher speed spinning, it is possible to lower the spinning tension, and the spun yarn can be softly wound around the bobbin. Good yarn can be twisted at high speed.

Further, the traveling surface of the traveler is gently inclined with an inclination angle of 2 ° to 4 °, so that the spindle rotation speed is 6,000 rpm. p. When spinning at a high speed of m or more, the centrifugal force exerts a force on the traveler to move downward along the traveling surface of the traveler, reducing local wear at the contact between the lower leg of the traveler and the lower surface of the ring. In addition, since the upper surface of the ring is formed by a flat surface, the contact between the upper surface of the ring and the head of the traveler becomes surface contact, and the local wear of the contact portion of the head of the traveler with the upper surface of the ring is reduced, and the distance between the ring and the traveler is reduced. Resistance can be reduced.

For this reason, the spinning tension can be reduced with a decrease in the contact resistance between the ring and the traveler.
It is possible to softly wind good-quality yarn with less fluff, and to extend the life of the traveler by reducing local wear at the contact portion with the traveler's ring. It can be extended and productivity can be greatly improved.

Since the thread relief surface is provided on the upper part of the ring body, it is possible to prevent a so-called trapping phenomenon in which the yarn is caught between the upper part of the ring body and the head of the traveler.
The quality of the yarn can be improved by reducing the damage to the fluff and the yarn.

Since the upper guide surface of the outer peripheral surface of the ring main body is inclined, even if the spinning tension applied to the traveler increases, the upper leg of the traveler does not come off from the upper guide surface of the ring, and the spindle rotates. The number can be increased, and productivity can be improved.

Further, since the upper surface of the flange portion is flat, it is easy to remove the short fiber dropped on the upper surface of the flange portion.
The number of steps required for cleaning can be reduced, and furthermore, it is possible to prevent a decrease in yarn quality due to the attachment of short fibers.

Further, since the reinforcing portion is provided on the outer peripheral portion of the flange portion, even if the height of the spinning ring is reduced and the outer diameter is increased, deformation or distortion during ring processing and heat treatment is reduced. Thus, a high quality spinning ring can be provided.

As described above, the spinning ring according to the present invention has the above-mentioned respective constitutional requirements, thereby exhibiting a synergistic effect obtained from the respective constitutions, and has a spindle rotation speed of 6,000 r.p. p. m, even in the high-speed range, which enables soft winding under a low spinning tension, and enables the production of high-quality twisted yarn with less fluff, and also improves productivity. This is an invention having excellent effects.
