The present invention relates to a double twist yarn and a double twist method, and more particularly, to double twist yarns of yarns of different elongation with less occurrence of twist unevenness or thread breakage.

First of all, the double twisting machine is to place a yarn feeding package on a stationary board, and to lower the thread guided to the lower side through a cylinder installed in the center of the yarn feeding package along the rotating disk disposed below the stationary board, In the process of guiding the thread in the ballonguide of the gas, it is added twice.

A conventional example of the double-twisted twisting machine will be described with reference to FIG. In FIG. 4, the support tube 1 is fixed to the frame 2, and the bearing 4 is interposed in the support tube 1, and the spindle 4 is rotatably supported. In addition, the warp 5, the drift disk 6, and the rotating disk 7 are fixed to the spindle 4 integrally. The belt 16 is connected to this warp 5, and the rotating disk 7 etc. rotate at high speed. In addition, the spindle 4 is supported by the stop plate 9 via the bearing 8, and the stop plate 9 is stopped by the suction action of the magnet 12 fixed to the stand 9. Maintain state.

Then, the yarn feeding cover 13 is fixed to the stopper 9, and the outer balloon limiting cylinder 14 is fixed to the frame 2 described above. A yarn feeding package P is placed on the stop plate 9, a tension device 15 is inserted in the core tube of the yarn feeding package P, and the tension device 15 is inserted into the core tube of the yarn feeding package P. The device 15 is inserted.

A plier 40 is inserted into the upper cylinder 22 of the tension device 15 so as to be movable, and the plier 40 is rotatably supported so as to be released on the cap 23 and rotated along it.

The pliers 40 are attached to the bosses 41 by bending the wires 42 in an octagonal shape.

As shown in FIG. 5, the snail wire 43 hangs on the front end of the wire 42. As shown in FIG. Moreover, the snail wire 43 is provided in the both ends of the wire 42, and a thread is attached to the snail wire 43 of either end.

The thread Y released from the yarn feeding package P passes through the snail wire 43 of the pliers 40, enters the upper cylinder 22 of the tension device 15, and the upper support member 24 and the upper support member 24. Predetermined tension is imparted by the capsel tensor 32 fitted to the lower support member 26, and guided to the thread extraction hole 18 via the passage 17 and the bend 17a.

Moreover, it is guided to the upper balloon guide 39 through between the yarn feed cover 13 and the outer balloon limit cylinder 14. At that time, the drift disk 6, that is, the rotating disk 7, is rotated by the driving force of the belt 16, and the thread Y is twisted twice. The pliers 40 are prevented from being broken and broken by increasing the angle θ that is released by rotating together with the yarn Y released from the yarn feeding package P to be greater than zero.

By the way, the snail wire 43 as a guide part of the first thread of the pliers 40 is placed on the upper side of the end face of the yarn feeding package P so that the yarn feeding package P as large as possible can be placed on the stop plate 9. It is intended to be located. Therefore, the yarn feeding package P can be enlarged by being placed inside the yarn feeding cover 13 without being disturbed by the pliers 40.

Twist inregularity or thread breaking when weaving yarns of different elongation, for example, filament and span weaving, and filament and spandex weaving double yarns. There was a problem that this occurred frequently. As a result of finding out the cause, as shown by the dashed-dotted line in FIG. 5, the end of the sudden-delayed package P should be removed from the upper end of the side of the sudden-received package P with a short route. As a result of a large traversal route, it has been found that many twist unevenness and thread breakage occur.

The present invention has been made in the process of identifying the cause of twist unevenness or thread breakage occurring in double twist yarns that are yarns of yarns of different elongation, and in the present invention, the invention described in claims 1 and 2 is It is an object of the present invention to provide a double twist yarn which does not cause thread breakage.

Moreover, the invention of Claim 3 aims at providing the double twisting method in which twist nonuniformity and thread break are not produced when double twisting yarns of yarns with different elongation.

In order to achieve the above object, the invention of claim 1 of the present invention, the steep package is placed on the stationary board, and the above-mentioned steep yarn is provided via a pliers freely rotated around a control installed in the center of the steep package. In the process of releasing the thread from the package, guide the released thread from the cylindrical body to the rotating disk disposed below the stop plate, and guide the thread to the upper balloon guide by following the thread on the rotating disk. A double twisting machine for twisting, the pliers are characterized in that they hold the first thread guide in a position facing the side of the sudden yarn package, and the pliers are provided with a counterweight.

When the original thread guide faces the package side, the unwinding thread does not cross the end face of the steep package.

In addition to the constitution of the invention as recited in claim 1, the invention described in claim 7 includes the pliers having one or more thread guides ranging from the first seal guide to the cylinder. It is characterized by.

One or more thread guides, from the original thread guide to the cylinder, tension the seal to prevent it from loosening.

In addition, the invention described in claim 3 is to untie the yarn by a pliers rotating along the periphery of the yarn yarn package from the yarn yarn wrapped in yarn of different elongation, and the unassembled yarn is standing in the center of the yarn yarn package. A double twist method of guiding twisted yarns in the process of guiding the twisted yarns to the rotating disc located at the lower side of the yarn yarns package by the installed cylinder, wherein the pliers are moved toward the position within the width of the yarn yarns package by the pliers described above. It is characterized in that it is released, guided to the cylinder while giving tension by a fraudulent pliers, and a counterweight is attached to the pliers, so that the rotation of the pliers is smooth.

Since it is easy to cross the end face of the package due to the loosening of the yarn of other yarns, especially the elongation, it is not possible to cross the end face of the package by having it pulled out towards the position (D) within the width of the sudden yarn package. At the same time, tension is imparted by the pliers to guide the cylinder to prevent loosening.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a cross-sectional view of the double thrower, Figure 2 is a view showing a flyer. In addition, the main part different from the conventional example of FIG. 4 is a shape of a pliers. Since other parts are the same as those in Fig. 4, the same reference numerals are used to omit the description.

In FIG. 1, the space | interval (epsilon) is provided between the yarn feed cover 13 and the side surface of the yarn feed package P, The pliers 50 are inserted in the space | interval (epsilon). The detailed structure of this pliers 50 is shown in FIG. FIG. 2A is a front view of the pliers 50, FIG. 2B is a side view of the pliers 50, and FIG. 2C is a plan view of the pliers 50. FIG.

In FIG. 2, the pliers 50 include a boss 51, a bent plate 52 fitted into and fixed to the boss 51, and a first thread guide 53 attached to the plate 2 rib. ), A second chamber guide portion 54 and a third chamber guide portion 55, and a counterweight 56 entangled with the plate 52.

The plate 52 is formed such that the first horizontal arm 57, the second horizontal arm 58, the inclined arm 59, and the vertical arm 60 are continuous.

The boss 51 is inserted into a hole in which the first horizontal arm 57 and the second horizontal arm 58 are located in the middle, and are fixed by bolts. The first thread guide portion 53 is attached to the lower side of the vertical arm 60, the second thread guide portion 54 is attached to the upper side of the vertical arm 60, and the first thread guide portion 54 is attached to the outer end of the second horizontal arm 58. The three-chamber guide part 55 is attached. The counterweight 56 is fixed to the outer end of the first horizontal arm 57 by bolts.

The first thread guide portion 53 has a hole 53a and a guide plate 53b facing the side of the yarn feeding package. The thread coming out of the hole 53a is diverted upward by about 90 ° along the guide plate 53b.

The second thread guide portion 54 is formed of a plate through which the thread passes. From the first thread guide portion 53, the thread is rubbed onto the plate of the second thread guide portion 54, and is switched in the direction inclined vertically toward the third thread guide portion 55. The third thread guide portion 55 holds the hole 55a, and the yarn slightly bends over the top of the cylinder not shown in the figure while passing through the hole 55a to change direction.

It returns to FIG. 1 and demonstrates.

The yarn from the sudden feeding package P to the top of the upper cylinder 22 includes the point A on the top of the upper cylinder 22, the point B on the third thread guide 55, and the second thread guide 54. The direction is switched while passing by four points of the point c and the point D of the first room guide portion 53.

A friction member 61 is attached to the lower surface of the pliers 50, and the friction member 61 portion is rotatable on the pan head 62 fitted to the upper cylinder 22. As shown in FIG.

The force information required for rotation of the pliers 50 can be adjusted by the weight 63 placed on the boss 51. Moreover, the center of gravity of the pliers 50 is exactly located in the boss 51 part, and the counterweight 56 of the appropriate weight is fixed by the bolt so that rotation of the pliers 50 may be smooth.

In the case of the pliers 40 having a simple shape as shown in FIG. 5, the pliers 40 can be balanced by forming left and right facing surfaces. However, in the case of the pliers 50 having a complicated shape as shown in FIG. 2, the whole becomes heavy and the structure becomes more complicated, so that the counterweight 56 is balanced.

In the double twist weaving machine having the above structure, the thread released from the yarn feeding package P exits toward the point D of the first yarn guide portion 53 facing the side surface of the yarn feeding package P. As shown in FIG. Therefore, regardless of the properties of the yarns, there is no possibility that the yarns to be unwound cross the upper end surface of the sudden yarn package P. FIG.

In addition, since the yarn turns only by about 90 ° from the point D of the first thread guide 53, tension is applied to the yarn. Moreover, since the thread is pressed against the plate at point C of the second guide portion 54 and rubs, the tension is applied to the thread. In addition, since the thread is pressed against the circumferential surface of the hole at point B of the third guide portion 55, the thread is given tension.

Then, at the point A of the upper cylinder 22 top, tension is applied to the yarn when the yarn is diverted more than 270 ° and guided to the upper cylinder 22. At the same time as the thread is released, the pliers 50 rotate along the circumference of the upper cylinder 22, and the rotational resistance of the pliers 50 can be adjusted by the weight 63.

That is, when the weight 63 is increased, the pliers 50 do not rotate well, and the tension applied after the point D becomes high.

In this way, if the configuration in which the predetermined tension can be sequentially added (D point C point C point B point A point) to the thread released from the yarn feeding package P is used, the released thread becomes the upper cylinder 22. It will not loosen until you reach). In particular, when yarns of different materials are different from each other when the yarns are different in elongation, when they start to loosen due to the effect of a bubble, the two strands of the yarn are separated, which causes twist unevenness.

However, by releasing the yarns from the sudden yarn package P and sequentially applying tension until reaching the upper cylinder, the braided yarns are not separated.

In addition, when the predetermined tension can be applied from the point D to the point C to the point B to the point A, the tension device 15 needs to be viewed.

Therefore, the capsel is removed because the tension device 15 is not operated.

When the double twist yarn of the above-described configuration is applied to the double twisting method of the sudden yarn package P in which the plywood with different elongation is wound, the advantage becomes clear. Since the elongation is a different thread, the thread constituting the plywood is separated from the steep package P to the cylinder to avoid the hot air, and looseness may occur in one thread. When such looseness occurs, it is easy to traverse the end surface of the upper side of the sudden package P. However, the first thread guide portion 53 of the pliers 50 not only pulls out the plywood toward the position (point D) within the width of the yarn feeding package P, but also the first of the pliers 50. The second and third thread guides 53, 54, and 55 sequentially apply tension to guide the upper cylinder to prevent loosening. Therefore, even if the elongation is a double twist yarn used for weaving yarns of different yarns, no twisting unevenness or thread breaking occurs.

Next, the form of another Example is demonstrated by FIG. The difference from that of FIG. 1 is that the second room guide is omitted, and only the first room guide 53 and the third room guide 55 are used.

In this case, since the yarn from the first chamber guide portion 53 to the third chamber guide portion 55 is intended to be the shortest distance, it is intended to be the apostle of a shown in the drawing. Therefore, the long hole 64 is processed in the vertical arm 60 and the inclined arm 59 of FIG. 2, and a thread passes through the space of this long hole 64. As shown in FIG. Since the wound diameter is large when the yarn feeding package P starts to be unwound, the thread from the first yarn guide portion 53 to the third yarn guide portion 55 does not reach the end of the yarn feeding package P, as in the apostle of b. However, there is no problem because the apostle b is slightly curved.

When the thread is thick and hardly affected by the hot melt, the thread guide part from the first thread guide part 53 to the upper cylinder 22 can be omitted. For example, when it becomes 15 deniers or more, the thing of FIG. 3 or the thing which abbreviate | omitted the 3rd thread guide part 53 can be used. However, due to the lack of tensioning on the thread, the capsel 32 of the tension device 15 is operated so that a predetermined tension is applied when the thread passes through the capcel 32.

As mentioned above, since the invention of Claim 1 used in this invention uses the pliers which pull out a thread from the thread guide which faces the side of a yarn feeding package, it becomes difficult for the thread to be unwound to cross the package end surface. It is possible to prevent twist unevenness or thread breakage caused by crossing the package end surface.

In addition to the invention effect of Claim 1, since the invention of Claim 1 prevents a thread from loosening to a cylinder after it is unwound, it can suppress the swelling of a thread and can obtain the processed yarn of stable quality. .

In the invention according to claim 3, when the double twisted yarn is obtained from a yarn yarn package in which yarns of different elongation are wound, the yarn yarn is unwound along the position (point D) within the width of the yarn yarn package. Guides to the cylinder with tension by one plier to prevent loosening of the weaving yarn and to avoid crossing the package end surface, resulting in twisting unevenness or thread breakage, which is a common occurrence in common double weaving methods. Can be prevented.
