1 is a perspective view of a yarn winding device as an example to which the fluff suppressing device of the present invention is applied, and FIG. 2 is a partial schematic side view of the yarn winding device. An example of the fluff suppressing device of the present invention will be described with reference to FIG. 3 and FIG. 4 which is an exploded perspective view of the twist preventing member as an example, but the present invention is not limited to this example as long as the gist of the present invention is not exceeded. It is not something that will be done.

After the yarn y is pulled out from the rewinding package 1, it is attached to a yarn guide 3 provided on an appropriate frame 2, a tension washer 4, and a support frame 5 provided upright on the frame 2. After being passed through the guide roller 6, it is sandwiched by the twist-preventing member S provided on the horizontal portion 7a of the support frame 7 standing on the frame 2, and then twisted by the twisting member T provided on the support frame 7. To be done. Twist member T
The yarn y twisted by means of the yarn passes through the yarn guide 8 attached to the supporting frame 7, the tension washers 11 and the yarn guides 12 respectively arranged on the appropriate supporting frames 9 and 10, and then by the traverse drum 13. The traverse drum 13 is traversed and gripped by a cradle arm (not shown).
And is wound into a package 14 which is driven to rotate. C is a tension adjusting member described later.

As shown in FIG. 4, the anti-twist member S described above has a pair of disc-shaped discs s1 having a substantially identical structure, which are reversibly rotated by contact friction with the yarn y. On the opposing surface of the dish-shaped disc s1, the ridges s2 are radially formed.
And concave portions s3 are formed alternately. Then, the pair of dish-shaped discs s1 is arranged such that the ridges s2 of the pair of dish-shaped discs s1 fit into the recesses s3 of the other opposing dish-shaped disc s1. Through hole s4 drilled in the center of the
The bolt s5 is inserted through the screw s5, and the tip of the bolt s5 is screwed into a screw hole 7a 'formed in the horizontal portion 7a of the support frame 7, whereby the bolt s5 is attached to the horizontal portion 7a of the support frame 7.

The twisting member T includes a barrel drum t1 having a rotation axis t1 'inclined at about 45 degrees with respect to the traveling direction of the yarn y and a rotation axis orthogonal to the rotation axis t1' of the barrel drum t1. barrel-shaped drum t2 having t2 ′, and barrel-shaped drums t1 and t2 are connected to each other in the yarn y
The barrel drums t1 and t2 are configured to nip the rotary shafts t1 ′ and t2 ′ via belts t1 ″ and t2 ″, respectively, by a driving device (not shown).
By rotating t2 ', it is configured to be positively driven to rotate.

The yarn y drawn out from the rewinding package 1 passes through the yarn guide 3, the tension washer 4 and the guide roller 6 and then the support frame 7 erected on the frame 2.
It is sandwiched by the anti-twisting member S arranged on the horizontal portion 7a of the slab, and then passes through the twisting member T arranged on the support frame 7, but the yarn y positively constitutes the twisting member T. It is nipped by the barrel-shaped drums t1 and t2 which are rotating at a constant angle and twisted between the twisting member T and the anti-twisting member S. The twist twisted by the twisting member T is prevented from propagating to the downstream direction of the twist preventing member S, that is, to the rewinding package 1 side by the twist preventing member S including the pair of dish-shaped discs s1. The yarn y is twisted between the twisting member T and the anti-twisting member S reliably and efficiently, and therefore,
The fluff protruding from the surface of the yarn y is caught in the yarn y to form the yarn y with reduced fluff. In this way, the yarn y that is caught in the yarn y between the twisting member T and the anti-twisting member S and has reduced fluff is the twisting member T.
The fluff does not jump out from the surface of the yarn y even when the twisted yarn that has been twisted through the yarn is returned, and the yarn y having a smooth surface can be obtained.

The residual torque of the yarn y is extinguished by being twisted between the twisting member T and the anti-twisting member S and then untwisted after passing through the twisting member T, so that almost no residual torque remains. The yarn y does not exist, and the yarn y in which no snare is generated is formed.

The tension adjusting member C has a horizontal rod c2 which is swingable around a pivot c1 provided at the upper end of a support frame 5 which is erected on the frame 2, and the pivot c1 is sandwiched therebetween. A weight c3 is disposed near one end of the horizontal rod c2 so that its position can be adjusted, and the other end of the horizontal rod c2 is sandwiched by the pivot c1. A tension filler c5 placed on the yarn y and extending downward via the bent portion c4 is formed. c6 is a vertical frame hung at an appropriate position of a horizontal rod c2 located between the pivot c1 and the tension filler c5, and a brake shoe c7 is attached to the lower end of the vertical frame c6. The brake shoe c7 is in contact with the body portion s6 of one or both of the pair of disc-shaped discs s1 constituting the anti-twist member S or the body portion s6.
It is arranged so as to be located above the dish-shaped disc s1 so as to be separated from. In this embodiment, the tension filler c5 is configured to come into contact with the yarn y located between the yarn guide 8 and the tension washer 11 after passing through the twisting member T.

The desired tension of the yarn y located between the yarn guide 8 and the tension washer 11 is distributed near one end of the horizontal rod c2 in consideration of the type and thickness of the yarn y. It is set by adjusting the weight and position of the provided weight c3.

When the tension of the yarn y located between the yarn guide 8 and the tension washer 11 after passing through the twisting member T becomes smaller than the desired tension, as shown in FIG. Then, the tension filler c5 moves downward, and accordingly, the horizontal rod c2 rotates in the clockwise direction in FIG. 2 about the pivot c1. By rotating the horizontal rod c2 about the pivot c1 in the clockwise direction, the brake shoe c7 attached to the lower end of the vertical frame c6 is moved to the disc-shaped disc s.
Since the disc-shaped disc s1 is brought into contact with the body s6 of the No. 1 and the disc-shaped disc s1 is braked, the rotation of the disc-shaped disc s1 that is being depolarized is suppressed, and the yarn sandwiched by the disc-shaped disc s1 The tension of the line y increases.

After passing through the twisting member T, the yarn guide 8
When the tension of the yarn y located between the tension washer 11 and the tension washer 11 becomes larger than the desired tension, the tension filler c5 moves upward as shown in FIG. The rod c2 rotates counterclockwise in FIG. 3 about the pivot c1. The counterclockwise rotation of the horizontal rod c2 about the pivot c1 causes the brake shoe c7 attached to the lower end of the vertical frame c6 to move away from the body s6 of the disc-shaped disc s1 to form a dish-like shape. Since the brake applied to the disc s1 is released, the dish-shaped disc s1 freely rotates, and the tension of the yarn y sandwiched by the disc-shaped disc s1 decreases.

As described above, by the tension adjusting member C,
Since the tension variation of the yarn y is controlled, the yarn breakage can be prevented and the package 14 having a good winding shape can be formed. Also, the twist member T
By controlling the tension of the yarn y after passing through the yarn in a desired range, fluctuations in the nip point of the yarn y due to the barrel drums t1 and t2 forming the yarn twisting member T are small, and therefore, the yarn twisting member T As a result, the twisting is constant, and more stable and uniform suppression of fluff can be realized.

In the embodiment described above, the twisting member T
The tension filler c5 of No. 1 is configured to contact the yarn y located between the yarn guide 8 and the tension washer 11 after passing through the twisting member T.
It can also be configured to contact the yarn y located between the tension washer 4 and the guide roller 6 before passing through the twisting member T.

Further, the movement of the horizontal rod c2, which is rotated by the displacement of the tension filler c5 due to the fluctuation of the tension of the yarn y, moves the upper tray 4a of the tension washer 4 in the vertical direction to move the yarn y by the tension washer 4. It is also possible to adjust the gripping force to control the tension of the yarn y. For example, the horizontal rod c2 located on the tension filler c5 side of the pivot c1 and the upper plate 4a of the tension washer 4 are connected by an appropriate connecting member, and the pivot of the horizontal rod c2 is associated with the vertical movement of the tension filler c5 due to tension fluctuation. The vertical rotation about c1 is transmitted to the upper plate 4a of the tension washer 4 via the connecting member, and the upper plate 4a is moved up and down to move the upper plate 4 of the tension washer 4.
The tension of the yarn y can be controlled by adjusting the gripping force of the yarn y by the a and the lower tray 4b.

The arrangement of the thread guide 3, the tension washer 4, the guide roller 6, the thread guide 8, the tension washer 11, the thread guide 12 and the like is not limited to the above-described embodiment, and various arrangement examples are possible. In addition to being adopted, various known thread guides or tension members can be used as thread guides or tension washers. Further, in addition to the twisting member T shown in the above-mentioned embodiment, a friction false twisting device used in a bulky processed yarn manufacturing apparatus or the like, or a twisting member using vortex jet air may be used. As long as it is possible and prevents the propagation of the twist twisted by the twisting member T, it is not limited to the above-described twist stopping member S.

[0020]

Since the present invention is configured as described above, it has the following effects.

Since the tension adjusting member controls the fluctuation of the tension of the yarn, it is possible to prevent the yarn breakage and form a package having a good winding shape.

Since the tension of the yarn is controlled within the desired range,
The fluctuation of the nip point of the yarn due to the twisting member is small, so that the twisting by the twisting member is constant, and more stable and uniform suppression of fluff can be realized.

Since the tension adjusting member has a simple structure having a brake shoe for braking the dish-shaped disc of the anti-twist member, the fluff suppressing device can be downsized and the maintenance and inspection can be simplified. it can.

By twisting the yarn between the twisting member and the anti-twist member, the residual torque of the yarn can be reduced, so that a yarn with less snare can be manufactured.
