Description

[Detailed Description of the Invention] [Industrial Application lfF] The present invention relates to a braking device for a rotating ring used in an ultra-high-speed ring spinning machine, and more specifically relates to a braking device for a rotating ring used in an ultra-high-speed ring spinning machine, and more specifically relates to a braking device for a rotating ring used in an ultra-high-speed ring spinning machine. The present invention relates to a braking device for smoothly stopping the vehicle.

[Conventional technology]

A rotating ring that rotates the ring 11 times in synchronization with the spindle has been proposed as a means for rotating the spinning warehouse of the ring 1M machine. This rotating ring can reduce the relative 1 degree between the trapeller and the rotating ring during spinning, and can reduce burnout and scattering of the trapeller due to increased frictional resistance, as well as yarn breakage caused by these problems. can. Therefore, compared to American spinning machines with fixed rings, spindles are significantly taller.

[Problem that the invention seeks to solve]

However, when the rotating ring is used, when the spindle stops, the spindle stops relatively quickly due to the frictional resistance acting between it and the bearing member. The rotating ring has a smaller frictional resistance than the former, and the rotating ring tends to continue rotating due to inertia even after the spindle has stopped. This state is illustrated in Figure 9 (a).
) is shown with a solid line.

As a result, the spindle yarn wound on the spindle, which has already reached the stopped state, is unwound and wrapped around the trapella, etc., causing trouble in the doffing operation. It is necessary to stop the inertia transmission of the rotating ring until the number falls below a predetermined value, and for this purpose various types of braking devices have been proposed. However, the conventional braking device has a complicated structure and uses a mechanical braking method using brake shoes, making it difficult to maintain the braking start timing and braking force under stable conditions over a long period of time. Moreover, sudden braking is often applied, causing problems such as the trapela's running posture becoming unstable and thread breakage occurring.

SUMMARY OF THE INVENTION It is an object of the present invention to address this problem and provide a rotary ring braking device using hydraulic braking that can solve the above-mentioned problems when braking a rotary ring.

[Means for solving problems]

The present invention for achieving the above object will be explained using FIGS. 1 to 5 corresponding to the first embodiment.

The rotating ring braking device 20 of the present invention includes a rotating ring 1 that includes a rotating member 2 having a ring body 4 and a support member 3 that rotatably supports the rotating member 2. The rotating ring braking device 20 is installed vertically below the rotating member. The brake ring 21 is provided with a brake ring 21 and an oil tank 22 into which the brake ring is inserted, and the rotation of the brake ring 21 is controlled by the hydraulic pressure in the oil tank 22.

[Effect]

When the spindle is stopped, by immersing the brake ring in oil in the oil tank, the rotating parts can be smoothly inserted without causing shock due to the hydraulic pressure from the oil.
n Make a right curve and stop.

〔Example〕

Figures 1 to 5 show the first embodiment. The rotating ring 1 consists of a rotating member 2 and a support member 3 that supports the rotating member 2. The rotating member 2 includes a ring body 4, an intermediate ring 5 supporting the ring body 4, and a lower ring 6 attached to the lower part of the intermediate ring 5. Support member 3
comprises an annular housing 8 supporting an air carrying ring 7 opposite the intermediate ring 5, the annular housing 8 being attached to a ring rail 9. The air carrying ring 7 is molded from a breathable porous sintered metal material, and the air carrying ring 7 is attached to the housing 8! Drill four air holes 10 to release the air. 11 and 12 are upper and lower flanges provided on the rotating member 2 to face the upper and lower surfaces of the air carrying ring 7, and the upper and lower flanges 7 and the intermediate ring 5 have minute gaps with respect to the air carrying ring 7, and The two rotating members are supported in a floating manner by the air blown out from the support ring 7.

Reference numeral 13 denotes a pressure reducing valve communicating with the air introduction hole 1o, which lowers the pressure air supplied from the pressure air supply pipe 14 to a predetermined pressure and supplies it to the air carrying ring 7.

The rotary ring braking side 10 includes a cylindrical brake ring 21 hanging down from the lower ring 6, and this brake ring 2.
1 is inserted into the oil Ffi22. The oil tank 22 is attached to a mounting flange 23 connected to the Ringley/L/9, and the high viscosity oil tank/I/OL is connected to the oil f! It is supplied and discharged within 22.

The brake ring 21 forms a rotation resistance means 25 that provides resistance to brake oil in the oil tank during rotation. As this rotational resistance means, the inner and outer surfaces of the brake ring may be roughened, and the illustrated example shows serrations formed at right angles to the rotational direction.

In the above configuration, the switching valve 24 is normally operated to discharge the brake oil OL in the oil tank. As a result, in normal spinning operations, the rotating member 2 is rotated by the IIJ force with the trapeller (not shown) attached to the ring body 4 as the trapeller travels.

Next, when the spindle is stopped when the pipe is full, the switching valve 24 is rotated in conjunction with this, and the brake oil OL is supplied into the oil FfJ 22, so that the brake ring 21 is immersed. The brake ring 21 is thereby subjected to a braking force, which braking force is proportional to the rotational speed and the immersion height of the brake ring. Therefore, as the oil level in the oil 422 rises, the braking force increases and the rotating member 2 stops, and unlike conventional mechanical braking such as brake shoes, the rotating member uses hydraulic pressure when braking, and therefore produces a shock. Trapera often does not receive shadow 4 in the u1 kalpa of the ring. This braking procedure is shown in FIG. 9(b). That is, when the present invention is used, a smooth descending line is formed, unlike the rapid deceleration caused by the four-machine system shown in FIG.

6 and 7 show modified examples of the rotation resistance means formed in the brake ring, and the rotation resistance means 30 in FIG.
The new surface of the brake ring 31 has a pointed triangular shape, and as the oil level of the brake oil rises, the resistance means 30
It is possible to increase the immersion area in a geometric progression and make the velocity drop line steeper. In the figure, 32 is a serration formed on both the inside and outside surfaces.

The rotation resistance means 35 shown in FIG.
It is formed by forming.

Next, FIG. 8 shows a second embodiment. The rotating ring braking device 40 of this embodiment has a rotating member 2 of a rotating ring 1 similar to that of the previous example.
It consists of a brake ring 41 provided at the bottom of the brake ring 41 and an oil tank 42 that can be raised and lowered.The oil tank 42 always stores a certain amount of brake oil/l10L, and 'RR is located below the brake ring 41. During braking, this is raised so that the brake ring 41 is immersed in brake oil.

Reference numeral 43 is a lever for raising and lowering the oil tank, and the lever 43 is a lever for raising and lowering the oil tank.
(not shown). The rest of the structure is the same as that of the previous example, and the same parts are given the same reference numerals and explanations will be omitted.

Although each of the above embodiments shows an example in which the brake ring has a single cylindrical shape, the brake ring is not necessarily limited to this, and for example, a large number of blade-shaped brake rings may be arranged around the circumference. Of course, changes may be made as appropriate without departing from the spirit of the invention.

〔Effect of the invention〕

According to the present invention, the brake ring is attached to the rotating member including the ring body, and the brake ring is braked by the hydraulic pressure of the brake oil in the oil tank, so that no shock occurs during braking, and
A smooth deceleration curve is formed, and there is no sudden change in the increase or decrease in friction with the traveler, so there is no occurrence of thread breakage, etc. Furthermore, the device of the present invention has a simple overall structure, has no parts that wear out during use, and has the advantage of being able to maintain stable braking performance over a long period of time.
