Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-twisting device for continuously imparting twist (actual twist) to a yarn, and more particularly to a pot-type multi-twisting device, which is intended to speed up the process.

[0002]

2. Description of the Related Art Conventionally, a multi-twisting device such as a table twister has been widely put to practical use. This multi-twisting device draws a yarn from a stationary package downwards from the center of the package through a hollow spindle to rotate a spinning disk. After being taken out through a passage passing through a wall such as a wall, the yarn is generally rotated around the yarn supplying package while receiving a centrifugal force and air resistance.

In this type of multi-twisting device, the yarn exiting the rotary disk freely forms a balloon, so that the ballooning tension increases as the rotational speed of the rotary disk increases, causing problems such as fluff and single yarn breakage. . Therefore, as the number of rotations of the rotating disk increases, the centrifugal force and air resistance received by the yarn increase, and the balloon diameter increases and the yarn tension increases accordingly.

Therefore, as described in Japanese Utility Model Laid-Open No. 2-3479, there is proposed a device provided with a balloon restricting cylinder for restricting the balloon diameter of the yarn exiting the rotary disk within a predetermined range.

[0005]

However, even in the conventional pot type multi-twisting device provided with the above-mentioned balloon limiting cylinder, the yarn taken out from the yarn introducing hole of the rotating disk by the centrifugal force is substantially orthogonal to this. As the pot rotates at high speed, the yarn runs and rotates while making strong sliding contact with the inner wall of the limiting cylinder, and the yarn fluffs due to friction and the single yarn breaks. There was an unsolved problem of doing.

Therefore, the present invention provides a pot type multi-twisting device capable of preventing the occurrence of fluff and single yarn breakage due to friction in order to limit the diameter of the balloon, and being able to cope with an increase in the twisting speed. With the goal.

It is formed. Therefore, the yarn does not make strong sliding contact with the inner wall of the pot in the circumferential direction due to the rotation of the rotating body, and the yarn substantially receives the frictional resistance force only in the traveling direction. Moreover, since the inner peripheral wall surface of the intermediate tubular wall portion is inclined so as to have a small diameter on the rotation position side of the yarn guide hole,
Depending on the inclination angle, the centrifugal force acting on the yarn is appropriately suppressed, and the yarn is not properly pulled out by the centrifugal force, so that the yarn pool does not occur in the pot even when the high speed operation is performed.
As a result, the problem that the yarn is entangled or snare occurs and the yarn is broken is solved.

41 is a boss member 13 formed by a plurality of bolts 14.
Together with this, it is a fixed cover fixed to the frame 12. The fixed cover 42 is a first cover member 42 that covers the outer periphery of the pot 20.
And a second cover member 43 which is connected to the first cover member 42 and covers between the pot 20 and the yarn guide 18,
The first cover member 41 has a shape along the pot 20 so as to be spaced from the outer peripheral surface of the pot 20 by a constant gap. This fixed cover 41 divides the space inside and outside
It has a function of rotating the air in the vicinity of the moving area of the yarn Y from the pot 20 to the yarn guide 18 in the same direction as the pot 20 when the pot 20 rotates.

Next, the operation will be described. In the present embodiment configured as described above, the package 11 is set in the pot 20 in advance, and the tip of the yarn Y is set at the tenser 35 and the bobbin 10.
After passing the yarn Y through the inside to the yarn guide hole 17 and taken out to the outside of the package 11 through the yarn guide 18, the yarn is hooked on a predetermined yarn traveling path to the winding device (not shown) and The rotating means 15 is driven via the belt 34 by the driving means. At this time, the pot 20 rotates integrally with the rotating body 15 and the yarn Y is so-called double twisted (multi-twisted).

In this state, the pot 20 has a rotating body.
A cylindrical portion 22 that is separated from the cylindrical portion 15 by a predetermined distance, and an intermediate tubular portion (tilt guide portion) 23 that is located between the yarn introducing hole 17 and the cylindrical portion 22 and rotates integrally with the rotating body 15 are provided. The second inner peripheral wall surface 23a inclined so that the diameter of the cylindrical portion 22 side is larger than that of the rotating body 15 side between the cylindrical portion 22 and the rotation position of the yarn introducing hole 17 of the rotating body 15 has a predetermined size. Is formed in
By rotating the pot 20, the yarn Y does not come into strong sliding contact with the inner wall of the pot 20, especially the second inner peripheral wall surface 23a in the circumferential direction, and the yarn Y is substantially subjected to frictional resistance only in the traveling direction. It will be. Moreover, the second inner peripheral wall surface 23a
Since the distance from the upper contact point to the rotation axis of the rotating body 15 is set to the specific value as described above, the yarn Y that exits the yarn introducing hole 17 at the normal operating speed is substantially accelerated by the centrifugal force. Instead, the tension of the yarn Y is maintained at an appropriate value even when the high speed operation is performed. Further, since the balloon diameter of the yarn Y is kept small by the inner wall of the pot 20, the tension of the yarn Y is also kept low. Further, a swirling flow of air is formed by the rotation of the pot 20, and the yarn Y from the inside of the pot 20 to the yarn guide 18 is reached.
By reducing the air resistance force applied to the balloon, it is possible to form a stable balloon.

In addition, in this embodiment, as shown in FIG. 2 (a), the second inner peripheral wall surface 23a is inclined by a predetermined angle α so as to have a small diameter on the rotational position side of the yarn guiding hole 17. Therefore, the centrifugal force acting on the yarn Y is appropriately suppressed according to the value of the inclination angle α, and the withdrawal of the yarn Y by the centrifugal force is appropriately suppressed. On the other hand, as shown in the comparative example of FIG. 2B, in the case where the bottom wall portion 51 and the cylindrical wall 52 are substantially orthogonal to each other, the yarn pool 55 is generated and the yarn Y is entangled or snare There is a problem in that it is likely to occur and break. As a result of the experiment, in the present embodiment having the inclined inner peripheral surface 23a having the above-mentioned action,
Compared to the conventional one without such inclined surface, 1.
It was confirmed that the yarn quality problem due to the fluff and the single yarn breakage did not occur even if the yarn was operated at the operating speed (rotation speed) of 3 to 2 times.

The yarn Y that has passed through the yarn guide 18 is wound by a winding device (not shown) to form a twisted yarn winding package. Thus, in the present embodiment, as described above, the bottom wall portion 21 located on one end side of the package 11, the cylindrical portion 22 which is separated from the bottom wall portion 21 and has the maximum inner diameter, and the bottom wall portion
A pot 20 including an intermediate cylindrical portion 23 inclined so that the cylindrical portion 22 side has a larger diameter than the 21 side is provided, and an inner portion inclined so that the cylindrical portion 22 side has a larger diameter than the rotating body 15 side. Perimeter wall 23a
Since the intermediate cylindrical portion 23 forming the slanted inner peripheral surface 23a rotates integrally with the rotating body 15, the yarn Y from the yarn introducing hole 17 makes strong sliding contact with the inner wall of the pot in the circumferential direction. The problem of fluff and single yarn breakage is solved, and the tension of the yarn is maintained at an appropriate value even at high speed operation, and the occurrence of yarn accumulation is prevented. As a result, the problem that the yarn Y is entangled or snare is generated is solved.

Further, in this embodiment, the outer periphery of the pot 20 is covered with the first cover member 42 of the fixed cover 41, and the portion between the pot 20 and the yarn guide 18 is fixed.
When the pot 20 is covered with the second cover member 43 of 41 and the pot 20 rotates integrally with the rotating body 15, a swirl flow (air flow) in the pot rotation direction is formed in the fixed cover 41. Therefore, the air resistance in the rotation direction received by the outer peripheral surface of the pot 20 is reduced by this swirling flow, and the energy consumption for driving the pot can be reduced. Furthermore, by providing such a cover 41, noise generated by twisting work inside the cover 41 can be silenced, and a dustproof effect and improvement in reliability due to it can be expected, and each rotating pot side There is no risk of an operator touching the member or contacting an object scattered from the pot side, and safety is ensured.

In this embodiment, the intermediate tubular portion 23 is used as a pot.
Although it was partially formed only on the bottom wall side of 20, the predetermined angle α
In addition to changing the value of, the intermediate tube portion 23 may be formed to be large so as to occupy most of the area of the pot 20 in the height direction. Further, in that case, the pot may be composed of only the slant guide portion forming the slanted inner peripheral surface with the bottom wall portion, or a short cylindrical wall fixed or rotatable between the slant guide portion and the thread guide 18. May be provided. Further, instead of the intermediate tubular portion 23, an inclined guide portion may be provided only near the yarn guide hole. In that case, the inclined guide portion does not become an annular guide portion.

Further, in this embodiment, the magnets 31, 32 were installed on the bottom wall side of the pot 20, but as shown in FIG. 3, the opening end of the package protection cover 29 (the upper end in FIG. 3). It is also possible to provide a plurality of magnets 61 on the inner circumference of the (part) and a plurality of magnets 62 of the opposite polarity located at substantially the same height as the magnets 61 to suppress the rotation of the package protection cover 29. Alternatively, as shown in FIG. 4, a tensor case 76 having a circumferential groove portion 76g for mounting the magnet 71 is provided with a stepped fitting surface portion 76a and a thread passage portion 76b which are coaxial with each other.
The tensor case 76 is attached to the thread passage 76 by the fitting surface portion 76a.
package 11 so that b is coaxial with the axis of package 11
A means for suppressing rotation of the package protection cover 29 may be configured so as to be detachably fitted to the upper end portion in the figure and cooperate with the plurality of permanent magnets 62 on the frame 12 side.
The tenser 75 having the spherical weight 37 housed in the thread passage 76b of the tensor case 76 has the same thread tension adjusting function as the tenser 35 of the above-described example.

Further, as shown in FIG. 5, the pot 20 has a yarn guide 88 at the opening end (upper end in FIG. 5) of the pot 20.
A cover 83 that rotates together with the cover 83 may be attached. in this case,
A swirl flow is formed between the fixed cover 41 and the pot 20 in which the cover 83 is mounted, and the rotation resistance of the pot 20 is reduced, and the yarn Y is taken out from the yarn introducing hole 17 in the pot 20. Since it comes into sliding contact with the pot 20 only completely in the traveling direction until it reaches the guide 88, it is possible to eliminate the problems of fluff and single yarn breakage and to keep the tension of the yarn Y low while stabilizing the balloon shape. However, mounting the package 11 and removing the bobbin 10 are somewhat complicated.
