Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to two or three material yarns, which are individually twisted in the same direction and the same number of twists, and are twisted in the opposite direction by twisting them in opposite directions. The present invention relates to a device for manufacturing.

[0002]

2. Description of the Related Art FIG. 5 shows an example of a conventional plied yarn manufacturing apparatus. Spindles 35, 35, which rotate in the same direction at the same speed, are equipped with yarn supplying bobbins 36, 36, respectively. Material thread 3 released from thread bobbins 36, 36
7 and 37 are individually twisted by the rotation of the spindles 35 and 35, and the traverser 38 is used to twist both material yarns 37 and 37.
37 are aligned and wound once on the intermediate bobbin 39, then the intermediate bobbin 39 is mounted on the spindle 34 which rotates in the opposite direction, the wound material threads 37 and 37 are simultaneously drawn out, and both are rotated by the rotation of the spindle 34. It is a structure in which twisted yarns are twisted together and wound around a winding tube 40.

FIG. 6 shows a second example of a conventional apparatus for producing plied yarns. Material yarns 37, 37 released from yarn supplying bobbins 36, 36 mounted on spindles 35, 35, respectively. The lower twist is given by the rotation of the respective spindles 35, 35, both material yarns 37, 37 are aligned and wound around the feed roller 41, and then the ring traveler 43 is passed through the winding bobbin 42 which is rotationally driven by the spindle 33. It is a structure in which a plied yarn is manufactured by winding.

The ring traveler 43 of FIG. 6 orbits the take-up bobbin 42 at a speed which is delayed from the speed of the take-up bobbin 42 by the feeding speed of the yarn 44, and
The yarn 44 is traversed up and down, and the yarn 44 is moving so as to be uniformly wound around the peripheral surface of the winding bobbin 42. The material yarns 37, 37 to which the lower twist is given by the rotation of the yarn supplying spindles 35, 35 are twisted by the revolving operation of the ring traveler 43 and wound on the winding bobbin 42.

[0005]

In the above-mentioned conventional apparatus, in the case of making a plied yarn of two twists, two yarn feeding spindles 35, 35 and one compounding spindle (intermediate spindle of FIG. 5). Or the winding spindle of Fig. 6. The same shall apply hereinafter) 33 and 34 must be driven to rotate, and the weight of the yarn applied to the compounding yarn spindles 33 and 34 is the same as the weight of the yarn of the yarn supplying bobbin 36. Since the number of yarns is doubled, if one yarn is fed from one yarn feeding spindle, a total of 4 units of yarn must be rotated. When three material threads are twisted together, the number of yarn supply spindles is three, and the number of threads applied to one compounding thread spindle 33, 34 is three units. Therefore, a total of six units of yarn are rotationally driven. Must.

Therefore, there has been a problem that twisting energy corresponding to the number of material threads is required for each of the lower twist and the upper twist, and the power consumption of the apparatus is large. Further, in the compounding yarn spindles 33 and 34, if the length of the yarns is constant, twice as many yarns as the yarn supplying bobbin 36 are wound, so that the yarns are produced depending on the amount of the intermediate bobbin 39 or the winding bobbin 42. There is a problem in that the length of the yarn is restricted and the bobbin is large, and thus it is difficult to produce a long seamless yarn. Further, the conventional device shown in FIG. 5 requires two steps for manufacturing the plied yarn, which complicates the work, and the conventional device shown in FIG. 6 reduces productivity by limiting the orbital speed of the ring traveler 43. There was a problem of being low.

According to the present invention, there is provided a device which can solve the above-mentioned problems and can manufacture a plied yarn in one step, which requires less running cost than a conventional device and which can be easily enlarged. It is an issue.

[0008]

In the composite yarn twisting machine of the present invention, a bobbin frame 6 is mounted stationary on the upper end of a hollow spindle 1 having a spin guide 15 at its lower end, and the bobbin frame 6 is loaded with the bobbin frame 6. By rotating the spindle 1, the material threads 19, 21 released from the paper bobbins 18, 20 and the material thread 23 released by the separately provided fixed paper feed bobbin 22 are individually wound. The lower twist and the upper twist for the whole are given at the same time.

When manufacturing a three-ply plied yarn, when the two paper feed bobbins 18, 20 are mounted on the bobbin frame 6 in a vertical positional relationship, and when a two-ply plied yarn is manufactured, Only one sheet feeding bobbin 18 is mounted on the bobbin frame 6. The first material yarn 19 released from one of the yarn supplying bobbins 18 mounted on the bobbin frame 6 is the spindle 1
The hollow guide 2 is inserted into the hollow hole 2 and is wound around the spin guide 15 at the lower end to be pulled out downward. The third material yarn 21 released from the other paper feeding bobbin 20 when the two paper feeding bobbins are mounted on the bobbin frame 6 is provided on the spindle 1 through the second balloon guide 13 provided on the upper end of the bobbin frame 6. It is guided from the open side hole 11 to the hollow hole 2 and is wound around the spin guide 15 at the lower end to be pulled out downward.

The second material yarn 23 released from the externally placed yarn supplying bobbin 22 is guided to the hollow hole 2 from the side hole 11 provided in the spindle 1 through the balloon guide 12 placed on the upper extension of the spindle 1. Bottom spin guide 15

[0012]

Function: The yarn supplying bobbin 18 which is stationary on the spindle 1.
The first material yarn 19 released from the above is twisted at its lower end by the spin guide 15, so that the first twisted yarn corresponding to the rotation speed of the spindle 1 is given in the hollow hole 2.

The second guide 11 is guided to the side hole 11 of the spindle through a fixed balloon guide 12 above the spindle 1.
The material yarn 23 of No. 2 is given a ply twist corresponding to the number of rotations of the spindle 1 between the balloon guide 12 and the side hole 11 by the rotation of the side hole 11. The upper end of the second material yarn 23 guided from the side hole 11 to the hollow hole 2 turns at the side hole 11 at the same speed as the spindle 1, and the lower end turns at the spin guide 15 at the same speed as the spindle 1. The first material yarn 19 and the second material yarn 23 are not twisted in the hollow hole 2.

In the case where the bobbin frame 6 is provided with the two yarn supplying bobbins 18 and 20, the third material yarn 21 released from the third yarn supplying bobbin 20 is located at the upper end of the bobbin frame which remains stationary. While being guided from the second balloon guide 13 to the side hole 11 of the spindle, a lower twist corresponding to the rotation speed of the spindle 1 is applied. And this third material yarn 2
For the same reason as in the case of the second material yarn 23, No. 1 is not twisted with either the first material yarn 19 or the second material yarn 23 in the hollow hole 2.

First, second and third material threads 19, 2
The ply twist given to 3, 21 is given by fixing the upper end and twisting the lower end in the rotation direction of the spindle 1, and the ply twist given to the three material yarns 19, 23, 21 is all The same number in the same direction.

The material threads 19, 23, 21 drawn from the spin guide 15 at the lower end of the spindle 1 are twisted at the upper end by the rotation of the spindle 1 and twisted together. The upper twist given at this time is in the opposite direction to the lower twist, and the number of twists of the upper twist and the lower twist is the same as long as the structure is such that it is wound around the winding tube 27 as it is without providing a ring traveler or the like. If necessary, it is possible to wind the fiber while slightly untwisting it with a ring traveler or the like, and it is possible to make the number of twists of the upper twist slightly smaller than the number of twists of the lower twist.

According to the apparatus of the present invention, the number of spindles rotated when manufacturing the plied yarn is only one,
The weight of the thread on the spindle is also 1 if the yarn is double twisted.
Only the weight of one yarn supplying bobbin 18, and the weight of two yarn supplying bobbins 18 and 20 in the case of three twists. Therefore, the power consumption of the device is significantly reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing an embodiment of the present invention.
It shows an example of an apparatus for main twisting. Spindle 1
Has a hollow hole 2 in its axis, is rotatably supported by a bearing (3, 3) on a frame (not shown), and is rotationally driven via a belt (4) from a drive shaft (not shown).

At the upper end of the spindle 1, a bobbin frame 6 is rotatably supported by bearings 5 and 5, and a permanent magnet 7 embedded in the bobbin frame 6 and a permanent magnet 7 embedded in a stationary guide cylinder 8 are provided. The magnet 7 and the magnet 7 attract each other, so that the bobbin frame 6 remains stationary on the rotating spindle 1.

On the upper part of the spindle 1, a conical rotary flange 9 is provided so as to cover the lower side of the bobbin frame 6, and the stationary guide cylinder 8 in which the rotary flange 9 and the magnet 7 are embedded.
A ring-shaped yarn path 10 is formed between the two. Immediately below the rotary collar 9, two side holes 11, 11 communicating with the hollow hole 2 of the spindle are provided.

Two bobbin mounting shafts in the horizontal direction are vertically arranged on the bobbin frame 6, and a second balloon guide 13 located on an extension of the spindle 1 is formed at the top end thereof.

A bracket 14 is integrally formed on the lower end of the spindle 1. A spin roller 15 is axially supported by the bracket 14 in a direction perpendicular to the axis of the spindle 1, and the peripheral surface of the spin roller 15 is close to the opening at the lower end of the hollow hole 2. Further, a thread hole 16 is provided coaxially with the hollow hole 2 below the spin roller 15.

The first material yarn 19 released from the first yarn supplying bobbin 18 mounted on the bobbin mounting shaft below the bobbin frame 6 is directly guided to the opening of the upper end of the hollow hole 2 of the spindle, and the hollow hole After being wound around the spin roller 15 through 2 and drawn out from the thread hole 16 at the lower end.

Further, the third material yarn 21 released from the third yarn supplying bobbin 20 mounted on the bobbin mounting shaft above the bobbin frame 6 passes through the second balloon guide 13 of the bobbin frame 6 and moves to the bobbin frame 6 side. After being pulled out to the outside, guided from the side hole 11 into the hollow hole 2, and wound around the spin roller 15 in the same direction as the first material yarn 19, the thread hole 1 at the lower end
It is drawn from 6.

On the other hand, a second frame is provided at a fixed position of the frame (not shown).
The second material yarn 23, which is attached to the yarn supplying bobbin 22 and released from the second yarn supplying bobbin 22, passes through the yarn guide 24 and is further above the bobbin frame 6 at a position above the spindle 1
Of the spin roller in the same direction as the first and second material threads 19, 23 through the balloon guide 12 located on the extension of the bobbin frame 6, the outside of the bobbin frame 6, the side hole 11, and the hollow hole 2. After being wound around 15, the yarn is pulled out downward from the thread hole 16 at the lower end.

The material yarns 19, 23, and 21 wound around the spin roller 15 and pulled out downward from the yarn hole 16 are collected into one and passed through the delivery roller 26 and taken up by the take-up tube 27. The circumferential surface of the take-up tube 27 is in contact with the rotationally driven driving drum 28 in a freely rotating state, and is driven at a constant circumferential speed. Since the delivery roller 26 and the take-up tube 27 do not rotate around the axis of the drawn-out yarn 25, the drawn-out yarn 25 is not attached to the spin roller 15 at the lower end of the spindle 1.
And the delivery roller 26 are twisted together.

If the rotation direction of the spindle 1 is the direction shown by the arrow A in FIG. 1, the ply twist given to the three material yarns 19, 23 and 21 will be the direction shown in FIG.
The ply twist applied between the delivery roller 26 and the delivery roller 26 is in the direction shown in FIG. That is, the upper twist and the lower twist have opposite twist directions and the same number of twists.

The apparatus shown in FIG. 1 is an apparatus for producing a three-ply plied yarn, but if any one of the first, second, or third paper feeding bobbins is not installed, the two-ply It is possible to produce plied yarns. Generally, it is preferable to reduce the rotational load applied to the spindle 1, so it is reasonable to remove the first or third yarn supplying bobbin 18 or 20. In the apparatus shown in FIG. 1, the bobbin mounting shaft provided on the bobbin frame 6 is in the horizontal direction, but this is in consideration of the convenience of loading and unloading the first yarn supplying bobbin 18 and the third yarn supplying bobbin 20.

In the apparatus for producing only the double twisted plied yarn, the number of the yarn supplying bobbin 18 to be mounted on the bobbin frame 6 is always one. In this case, it is more rational to set the bobbin mounting axis in the vertical direction. Is. FIG. 4 shows an embodiment of an apparatus in which only one yarn supplying bobbin is mounted on the bobbin frame 6, and a first yarn supplying bobbin 18 is vertically mounted on the bobbin frame 6. 1 of the embodiment of FIG. 1 except that the first material yarn 19 released from the yarn supplying bobbin 18 is guided to the hollow hole 2 of the spindle 1 through the hollow hole 30 of the bobbin mounting shaft 29. There is no difference from the one obtained by removing the third yarn supplying bobbin 20.
Further, the action when the material yarns 19 and 23 are subjected to the lower twist and the upper twist is similar to that of the embodiment of FIG.

[0030]

According to the apparatus of the present invention described above,
An apparatus capable of producing a plied yarn in a single step is obtained, and further, the apparatus of the present invention has a structure in which a lower twist for a plurality of material threads and an upper twist for twisting a plurality of material threads are one spindle rotation. The structure is extremely simple since it is provided by only. In addition, since the weight of the yarn on the spindle can be reduced, the power consumption during operation can be reduced, and since only the yarn feeding bobbin is mounted on the spindle, it is possible to easily increase the size compared to conventional devices. The effect is that a much longer plied yarn can be efficiently produced.
