Description

[Detailed Description of the Invention] The present invention relates to a vibration prevention ring that prevents vibrations that occur when two fed yarns are combined and twisted using a double twister.

The lower yarn feeding package and the upper yarn feeding package are placed coaxially on the stationary disk of the double twister, and the upper yarn feeding package and the lower yarn feeding package pulled out from the upper yarn feeding package and the lower yarn feeding package are combined by the double twister. When winding twisted yarn into a winding package, when there are many yarns in the upper yarn supply package and the lower yarn supply package, even if the upper yarn supply and lower yarn supply align and interfere, the upper yarn supply will not be pulled out. Since the frictional resistance on the yarn feeding surface is large when the yarn is fed, it does not sag. However, when the amount of yarn fed in the upper yarn feeding package and the lower yarn feeding package decreases, if the upper yarn feeding package and the lower yarn feeding package interfere with alignment, the upper yarn feeding package will not sag. When the fed yarn is pulled out, the frictional resistance on the surface of the fed yarn is small, so if it is pulled out too much by the lower yarn feeder and becomes slack, it may cause looseness, and the looseness may be wound up into the winding package. When the same full package is used as the upper yarn feeding package and the lower yarn feeding package, the lower yarn feeding package pulled out from the lower yarn feeding package is pulled upward while contacting the yarn feeding surface of the upper yarn feeding package. Therefore, the frictional resistance during pulling out is greater than that of the upper yarn fed from the upper yarn feeding package, so as the tension increases, the elongation also increases. Moreover, when the upper yarn feeder is pulled out and disappears, there is a problem that the lower yarn feeder remains.

Therefore, in the present invention, a ring is loosely fitted onto the base of the guide pipe placed on the upper yarn supply package, and only the upper yarn supply is passed between the base and the ring and guided with frictional resistance. The above-mentioned problem is solved by introducing the yarn into the thread passing hole of the pipe and directly introducing the lower yarn feeder into the thread passing hole of the guide pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The double twister anti-shake ring according to the present invention will be described in detail below with reference to the drawings.

As shown in FIGS. 1 and 2, a small diameter portion 1 of a tapered upper yarn supply package Pa and a large diameter portion 2 of a tapered lower yarn supply package PB are removably coaxially connected, and are axially connected. A guide pipe 3 having a thread passing hole 4 is placed on the base 5 at the end of the large diameter part 2 of the upper yarn feeding package Pa, and a ring 6 is loosely fitted into the guide pipe 3, so that the base 5
is placed on top.

Incidentally, the upper end surface 7 of the guide pipe 3 and the base 5 of the guide pipe 3 are mirror-finished so that there is no slip resistance.

Further, the weight, diameter, and surface finish of the ring 6 can be changed as desired.

As shown in FIG. 3, the double twister 8 that twists the upper yarn yarn Ya and the lower yarn Yb pulled out from the upper yarn feeding package Pa and the lower yarn feeding package PB is a rotary disk fixed to a spindle 9. A stationary disk 11 is placed on the stationary disk 10, and the stationary disk 11 maintains a stationary state even when the rotary disk 10 rotates due to the magnetic force of a magnet (not shown) of the stationary disk 11 and a magnet 12.

The rotary disk 10 and the stationary disk 11 are provided with a thread passage hole (not shown) that communicates with the thread outlet hole 13 of the rotary disk 10.

Rope 1.14 is the drive belt.

The base 5 of the guide pipe 3 is the upper yarn feeding package P.
The small diameter portion 1 of the upper yarn feeding package Pa and the large diameter portion 2 of the lower yarn feeding package pb are connected to each other, and the small diameter portion 1 of the lower yarn feeding package pb is placed on the large diameter portion 2 of the stationary disk 11. By being placed in the center, the yarn guide hole 4 of the guide pipe 3 connects the shaft holes 15 of the upper yarn supply package Pa and the lower yarn supply package PB, the unillustrated yarn passage holes of the stationary disk 11 and the rotary disk 10. It communicates with the yarn outlet hole 13 of the rotary disk 10 through the thread.

Therefore, as shown in FIGS. 1 and 3, the yarn feeding large diameter section 1
The upper yarn supply yarn Ya pulled out from the upper yarn supply package Pa with the yarn supply yarn 6 positioned above is passed between the base 5 of the guide pipe 3 and the ring 6, and is passed through the lower yarn supply package Pa with the yarn supply large diameter section 17 positioned above. Lower yarn feeder Yb pulled out from yarn feeder package pb
At the same time, the thread Y is introduced through the thread passing hole 4 of the guide pipe 3 and led out from the thread outlet hole 13 of the rotary disk 10, and then twisted by the double twister 8. 19, it is wound up into a winding package 22 via a feed roller 20 and a traverse guide 21.

When the same full package is used as the upper yarn feeding package Pa and the lower yarn feeding package PB, the upper yarn feeding Ya is introduced into the yarn passing hole 4 of the guide pipe 3 through between the base 5 and the ring 6, and the lower yarn feeding package By directly introducing the yarn feeding Yb into the yarn passing hole 4, the upper yarn feeding package Pa and the lower yarn feeding package pb are formed as shown in FIG.
Even when there is a large amount of yarn being fed, or even when there is a small amount of yarn being fed as shown in FIG. Since the ring 6 pushes down onto the base 5 between them and applies frictional resistance, the upper yarn feed Ya and the lower yarn feed Y
It is possible to prevent the yarns b from aligning and interfering with each other, and it is also possible to prevent the upper yarn feeding yarn Ya from sagging and causing kinks, and is effective not only for weak torque yarns but also for strong torque yarns. .

In addition, the frictional resistance of the upper yarn yarn Ya, which is the sum of the frictional resistance when the upper yarn yarn Ya is pulled out from the upper yarn yarn package Pa and slides on the yarn feeding large diameter portion 16 and the frictional resistance imparted by the ring 6, is The frictional resistance is the sum of the frictional resistance when the yarn feeding Yb is pulled out from the lower yarn feeding package pb and slides on the yarn feeding large diameter section 17, and the frictional resistance when it slides on the yarn feeding large diameter section 16 of the upper yarn feeding package Pa. By adjusting the weight and diameter of the rings so that they are equal, the upper yarn feed Ya and the lower yarn feed Y
b is introduced into the thread passing hole 4 of the guide pipe 3 with the same pulling tension, and it is possible to obtain a plied and twisted yarn Y with uniform tension.Furthermore, since the frictional resistance applied to the upper yarn feeding Ya and the lower yarn feeding Yb are equal, the upper The elongation of the yarn feeding Ya and the lower yarn feeding Yb become equal, and the upper yarn feeding package Pa and the lower yarn feeding package Pb are formed.
becomes empty almost simultaneously.

As described above, according to the present invention, only the upper yarn feeding yarn pulled out from the upper yarn feeding package is passed between the base and the ring and pushed down onto the base to apply frictional resistance, thereby introducing it into the yarn passing hole of the guide pipe. By directly introducing the lower fed yarn pulled out from the lower yarn feeding package into the yarn passing hole, it is possible to prevent the upper fed yarn from interfering with the lower fed yarn pulled out from the lower yarn feeding package, and to prevent the upper fed yarn from interfering with the lower fed yarn pulled out from the lower yarn feeding package. It can prevent the yarn from becoming loose, and the total frictional resistance when the upper yarn feeder slides between the upper yarn feeder package and the base and the ring, and the lower yarn feeder slides between the lower yarn feeder package and the upper yarn feeder package. Since the total frictional resistance at the time is equal, it is possible to pull out the upper fed yarn and lower fed yarn with the same tension to combine and twist the yarn, and the elongation due to pulling out the upper fed yarn and lower fed yarn is equal, so that the upper fed yarn The package and the lower yarn feed package can be emptied at the same time.
