Abstract

PROBLEM TO BE SOLVED: To provide the spinning machine method ultrasonic vibrators on its top rollers, which make the rotation of each bearing of its top rollers smooth by means of ultrasonic vibration. SOLUTION: Ultrasonic vibrators 26 allow each end brush 7a, 9a, 11a and 13a of top rollers to be pressed by each spring 20 provided between each spring support member and each spring receiving member 26a provided for the ultrasonic vibrators 26, and also allow ultrasonic vibration to be well transmitted with the strength of each spring 20 adjusted by adjusting screws 21, so that ultrasonic waves generated by the ultrasonic vibrators 26 are thereby transmitted to the end bushes 7a, 9a, 11a and 13a. Since this constitution thereby allows each internal bearing of the end bushes 7a, 9a, 11a and 13a to be ultrasonically vibrated, the balls and rollers of each bearing are instantly brought into contact with each rotating shaft of the top rollers or the end bushes, or released therefrom, the contact of each bearing thereby beomes shorter in time, and contact friction is also thereby reduced, so that the service life of each bearing is therefore prolonged.

[0004]

However, recently,
Although there is a tendency to make the top roller of the spinning machine rotate faster, in the spinning machine configured as described above, when the rotation speed is increased, a large load is applied to the bearing in order to rotationally support the long top roller, and thus the bearing is There is a problem that friction heat is generated in the fluff, and the overheat ignites the fly and the wear becomes faster, and the bearings are frequently replaced.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a spinning machine in which a top roller is placed on a bottom roller, and an embush of the top roller is pressed by a press pin. An ultrasonic vibrator is attached to the above with a fixing member, and the ultrasonic vibrator is vibrated to smoothly rotate the bearing of the end bush.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the bearing vibrates ultrasonically by transmitting ultrasonic waves from the ultrasonic vibrator to the end bush of the top roller, so that the ball or roller of the bearing is on the rotating shaft side or the end bush. As it comes into contact with or separates from the side instantaneously, each contact time is shorter than conventional bearings, contact friction is reduced, and the bearing rotates smoothly,
It has the advantages of less wear and a longer bearing life.

Is a clasp support member, 23 is a V-shaped clasp, 24 is a lever member, and 25 is a rotating shaft. Since these configurations are the same as those of the conventional example described above, description thereof will be omitted, but the present embodiment. Then, an ultrasonic transducer 26 is attached instead of the presser pin 19, a spring 20 is received by a spring receiving member 26a provided at a node portion of the ultrasonic transducer 26, and the strength of the spring 20 is adjusted by an adjusting screw 21. The tip of the ultrasonic transducer 26 is the spring 20 and the end bushes 7a, 9 of the top rollers 7, 9, 11, 13 are connected.
The ultrasonic vibration is transmitted well by pressing a, 11a and 13a.

In this ultrasonic vibrator 26, a ring-shaped piezoelectric vibrator (not shown) is sandwiched between two metal blocks, and bolts provided with screws at both ends are attached to the central hole of the piezoelectric vibrator. It is a bolted Langevin type in which the screws at both ends are fitted into the screw holes of the two metal blocks and are integrally configured. When a voltage at the resonance frequency is applied to this piezoelectric body vibrator, the piezoelectric body vibrator Ultrasonic vibrations are magnified by the metal block and generate powerful ultrasonic waves at the tip.

When the ultrasonic waves generated by the ultrasonic transducer 26 are transmitted to the end bushes 7a, 9a, 11a, 13a of the top rollers 7, 9, 11, 13 in this way, the end bushes 7a, 9a, 11a, 13a. Since the bearing inside the ultrasonic wave vibrates ultrasonically, the ball or roller of the bearing momentarily contacts with or separates from the rotating shaft side or the end bush side of the top rollers 7, 9, 11, 13 and thus the contact time. Shorter, thus reducing contact friction,
The bearing rotates smoothly, wear is reduced, and the life of the bearing is extended.

As is apparent from the above description, in the spinning machine of the present invention in which the ultrasonic vibrator is mounted on the top roller, when the ultrasonic wave is transmitted from the ultrasonic vibrator to the end bush of the top roller, the bearing is superposed. By vibrating the sound wave, the ball or roller of the bearing momentarily contacts with or separates from the rotating shaft side or the end bush side, so the contact time of each becomes shorter compared to conventional bearings, and contact friction is reduced. It has the advantages of reduced wear, smoother bearing rotation, less wear and longer bearing life.
