Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing process in which two or more yarns drawn from a plurality of yarn supply sources are separately drawn, then drawn and aligned to be combined and twisted to form a cheese-like package. Concerning the compound yarn machine.

[0002]

2. Description of the Related Art Generally, a ply-twisting machine or a double-twisting machine is used when two yarns are aligned and plied together. When using a yarn twisting machine, the yarns pulled out from the package mounted on the creel are not subjected to uneven tension in order to prevent loops and tarmi from occurring in the yarns obtained. As described above, after passing through a tension adjusting device such as a gate tensor or a ball tensor for each spindle, it is wound up in a pan shape by a ring traveler winding mechanism. On the other hand, when using a double twisting machine to combine yarns, place two supply packages inside the spindle, twist the yarns drawn from this package with the double twist spindle, and then separate from the spindle. On the other hand, the so-called sun-cheese method in which it is wound outside, and in contrast to this, for example, two supply packages are arranged on a creel that is arranged separately from the double-twisted-spindle spindle, and the yarns drawn from this package are aligned and then There is a double-twisted-spindle system with a winding device that twists a heavy-twisted-thread spindle and winds it around a flange bobbin built into the spindle. Among them, the former sun cheese method has a restriction on the winding amount and winding shape of the supply package because the supply package is arranged inside the spindle, and thus a preparation process is required to ensure that the supply package has a uniform shape. Become. On the other hand, the double-twisted-spindle system with a winding device has no restrictions on the winding amount and winding shape of the supply package.

[0003]

However, in recent years, the appearance of woven and knitted fabrics,
As a high-value-added yarn that remarkably improves properties such as texture and bulkiness, new synthetic yarns such as so-called different-shrink mixed yarns of multifilament composed of two or more yarns having different shrinkage ratios are expected to spread. Has become. When yarns having different shrinkage properties such as different shrinkage mixed yarns are aligned and plied together, a conventional ply-twisting machine having a tension adjusting device for each spindle or a double-plying machine with a winding device is used. There is a new case that cannot be dealt with. That is, since the contraction properties of the supplied yarns are different, even if the yarns are combined through a tension adjusting device for each one of the folding angles, the yarns obtained after the combining yarns do not have a uniform appearance. However, there was a problem in that the irregular shape including loops and tarmi was formed, and the initially expected aligned yarn could not be obtained. In addition, when the wound package is wound by the ring traveler mechanism of the ply yarn twisting machine, it has a bun shape, so that when the bun is released from the bun at the taper end in the next step, the yarn breaks frequently. Therefore, the present invention has been devised as a solution to this problem, and its purpose is to provide no loops or tarmi even if the yarn to be twisted is a new synthetic fiber such as a different shrinkage mixed fiber. It is intended to provide a ply-twisting machine capable of obtaining a ply-twisted yarn having a uniform appearance.

[0004]

The present invention has solved the above problems by taking the following means. That is, from a first feed roller and a separator roller and a stretch roller, which consist of a plurality of upper and lower yarn supplying portions and a pair of nip rollers for stretching at least two yarns drawn out from the yarn supplying portions at different stretching ratios. Having a second feed roller, a yarn guide for twisting two yarns that have passed through the stretch portion, and a twist angle after twisting the yarns that have passed through the yarn guide. A double twisted yarn spindle with a winding device for winding the cheese-like package is provided. More specifically, this will be described in more detail below. Under the yarn supply creel in upper and lower stages, first feed rollers composed of a pair of nip rollers are provided in upper and lower stages. Among them, the upper feed roller is eccentrically arranged so as to be forward of the shaft center of the lower feed roller when viewed from the yarn operating side, and the yarn pulled out from the supply yarn of the upper creel is fed to the lower first feed roller, while Guides for guiding the yarns drawn from the supply yarn of the lower stage creel to the upper stage feed roller are provided respectively. Further, the second feed roller composed of a separator roller and a stretch roller for aligning two yarns fed from the upper and lower first feed rollers and aligning them in a stretched or relaxed state is a lower first feed roller. It is located at the lower part of the table and approximately in the middle of the adjacent feed rollers. Further, a double twisted yarn spindle with a winding device for winding up as a cheese-like package having a traverse angle is arranged below the second feed roller.

[0005]

[Function] When two or more kinds of synthetic fiber yarns having different shrinkability are combined and wound, the yarns are supplied from the upper and lower stages of the yarn supplying creel.
Each yarn is drawn out by a feed roller composed of a pair of nip rollers at different speeds, and both are drawn through an independent stretching zone or relaxation zone and then twisted and wound. In this case, the feed rollers, which serve as nip rollers for drawing out the supplied yarn, are arranged vertically, the upper feed roller is eccentric from the axis of the lower feed roller, and is arranged on the front side (front side) when viewed from the yarn operating side. The yarn drawn from the upper creel is fed to the lower feed roller, while the yarn drawn from the lower creel is fed to the upper feed roller.Therefore, the yarns do not intersect with each other and have different shrinkage. Since the optimum tension can be imparted to each yarn, the yarns aligned and aligned can have a uniform appearance without irregular loops or tarmi. Further, since the winding shape of the package wound by the double twisted yarn spindle with the winding device has a predetermined traverse angle, even in the case of the new synthetic fiber, compared with the package wound by the conventional ring traveler mechanism. , Releasability is very good.

An example of the draw-ply twisting machine for carrying out the present invention is constructed as described above. Next, the operating state thereof will be described. The yarn drawn from the package A mounted on the upper stage creel 1 is described below. YA is guided to the yarn guide 7 via the pressure roller 4b of the lower feed roller 4 and the delivery roller 4a1 via the yarn guides 5a and 5b, and then surrounded by the separator roller 8a and the stretch roller 8b of the second feed roller 8 several times. After that, it is further guided to the snell wire 9. On the other hand, the yarn YB pulled out from the package B mounted on the lower creel 2 has the yarn guide 6
a, 6b, the pressure roller 3b of the upper first feed roller 3, the delivery roller 3a, and the guided yarn guide 7, where the yarn YA drawn from the package A1 of the upper creel 1 is mixed with the yarn. Surrounded several times by the separator roller 8a and the stretch roller 8b,
It is guided to the snell wire 9. By the way, in the case where the packages A and B respectively mounted on the creel 1 and 2 are yarns of different shrinkage such as different shrinkage mixed fiber,
The peripheral speeds of the stretch rollers 8b of the feed roller 8 may be different from those of the first feed rollers 3 and 4. That is, when the peripheral speeds of the stretch roller 8b are different from those of the upper first feed roller 3 and the lower first feed roller 4, the yarns YA and YB are independently stretched or relaxed during this period. Here, the draw ratio or relaxation ratio of each yarn YA and YB should be the same as the experience obtained from the experimental results depending on the type and fineness of the yarn so that the appearance of the yarn Y obtained by aligning and combining the yarns is uniform. Determined based on value. The yarn is then twisted with a double twist spindle with a winding device.

The operation of the double-twisted yarn spindle device with the winding device will be described below. In FIG. 3, the hollow spindle blade 11 has a timing pulley driven by a machine belt drive source (not shown) via a timing belt. By doing so, the bolster 14 is rotated. Therefore, the bowl-shaped thread turntable 11b fixed to the hollow spindle blade 11 rotates. Even when the hollow spindle 11 and the yarn storage rotary disk 11b rotate, the stationary disk 23 remains stationary due to its own weight and the weight 24. On the other hand, when the drive body 17 having the permanent magnets 17a is driven from the machine frame drive source via the timing belt 20 and rotates on the outer peripheral portion of the bolster 14, an appropriate gap is interposed with the bottom plate of the yarn storage rotary disk 11b interposed therebetween. Then this driver 17
The driven body 21 forming a pair with is driven to rotate on the outer peripheral portion of the spindle blade 11. When the driven body 21 rotates, the drive shaft 30 is passed through a timing belt 29 that engages with a timing pulley attached to the driven body 21.
Rotates. When the drive shaft 30 rotates, the drive roller 38 rotates via the timing belt 27 that engages with the timing pulley 35 attached to the drive shaft 30. As a result, the drive roller 38 and the contact pressure mechanism 4
The take-up bobbin 53, which is constantly in pressure contact by 2, is driven by the surface frictional force. The overfeed roller 33 attached to the tip of the drive shaft 30 is also driven. On the other hand, when the winding bobbin 53 is driven, the bobbin holder 40 in which the winding bobbin 53 is fixed by the basket spring 52 is driven, so that the spur gear 39 and the spur gear 3 attached to the bobbin holder 40 are driven.
The speed reduction mechanism 37 and the bevel gears 46 and 45 are driven via the drive shaft 8, and as a result, the traverse cam shaft 33 is driven, so that the traverse guide 44 performs a traverse motion.

By the way, the yarn Y passing through the snell wire 9
Is guided to the thread pool turntable 11b while drawing ballooning. Next, the yarn Y passes through the center hole 11a of the hollow spindle blade 11 and passes through the bobbin holder 50 while drawing a so-called storage by surrounding the bottom of the yarn storage turntable 11b about 1/2 to 2 times. It is guided to the guide roller 34. Here, the yarn Y is twisted between the snell wire 9 and the guide roller 34. The yarn Y passing through the guide roller 34 is then fed to the overfeed roller 33.
It is pulled out by the above-mentioned method and is wound on the take-up bobbin 53 through the traverse guide 44. Even if the winding progresses and the winding diameter of the winding bobbin 53 increases, the driving roller 3
Since the arm 40 rotates in response to the increase of the winding diameter in response to the increase in the winding diameter, the drive roller 38 attached to the arm 40 and the winding bobbin 53 are always in contact with each other, and therefore the yarn is Article Y always bobbin 5 at constant winding speed
It is wound up in 3.

After being stretched here, the feed roller 8
When the yarn sent out from the reel is wound by the double twisted yarn spindle 10 with the winding device, a tension adjusting device may be arranged between the snell wire 9 and the feed roller 8. This is because, in the normal case, the yarns are half
It is a mechanism that absorbs or alleviates the tension fluctuations from the snell wire 9 to the yarn pool rotating part while drawing the balloon by increasing or decreasing the so-called storage that is surrounded by about 2 times. In some cases, tension adjustment may be necessary in addition to this. Depending on the yarn Y, an interlace nozzle (for example, Japanese Patent Publication No. 36-12230 or Japanese Patent Publication No. 37-37) may be provided below the second feed roller 8.
(Described in Japanese Patent No. 1175) may be arranged. Further, depending on the yarn, a heat treatment device such as a hot pin or a heater may be arranged in the drawing part.

FIG. 10 shows the other side of the stretched ply yarn machine of the present invention, 61 of which is a working passage, and this passage 61
The yarn supplying section 62 having a plurality of yarn supplying creels is arranged on one side of the interposing side, and at least two yarns are drawn or relaxed at different drawing ratios on the other side. This is a case where the drawing section 63 and the double-twisted-pile spindle 10 with a winding device for aligning the yarns sent out from the drawing section, aligning the yarns, and twisting and winding the yarns are arranged.

FIG. 11 shows another example of the stretched and twisted yarn machine of the present invention. In this stretched and twisted yarn machine, a yarn is provided between the feed roller 8 and the double twisted yarn spindle 10 with a winding device. This is a case where the storage device 70 and the tension adjusting device 76 are arranged. The yarn accumulating device 70 is composed of a cylindrical drum that is rotated by a drive motor 71, and when the yarn Y sent out from the feed roller 8 is wound by the double twisting yarn spindle 10 with a winding device, it is When the winding speed does not follow up, it controls the amount of yarn stored temporarily. On the other hand, the tension adjusting device 7
6 is for adjusting the tension fluctuation when the yarn is sent from the storage device 70 to the double twist yarn spindle 10 with the winding device. Now, the yarn Y1 pulled out from the two packages,
Y2 is the first feed roller 3 and the second feed roller 8
Between the storage device 7 and the storage device 7 respectively.
After being surrounded several times by the outer circumference of the cylindrical drum of 0, the guide 75
The tension fluctuation is adjusted by the tension adjusting device 76 through the yarn feeding device, and further, the yarn is wound on the double twisting yarn spindle 10 with the winding device through the compounding yarn guide 77. At this time, the storage amount sensor 72
However, when the storage amount of the storage device 70 increases or decreases from a predetermined amount, a signal is sent to the control device 73, and the storage device 7
If the storage amount becomes large by operating the drive motor 71 of 0 and the extension unit drive motor 74, for example, the drive motor 71
And the extension part drive motor 74 are decelerated. On the other hand, when the storage amount decreases, the drive motor 71
And the drive motor 74 is accelerated.

Further, FIG. 12 shows an example in which the drive sources of the drive rollers in the drawing section are independent for each weight, as compared with the draw compounding and twisting machine shown in FIG. In the case of this example, when the surface frictional force between the winding bobbin 53 and the drive roller 38 of the take-up / feeding double-twisted-yarn spindle 10 differs for each adjacent weight, the drive yarn of the double-twisted-yarn spindle 10 with a take-up device is If all spindles are driven by the same drive source, the winding speed of the double-twisted yarn spindle will not be perfectly synchronized with the feeding speed of the yarn from the drawing section, and winding will be impossible. This is to avoid that. That is, even if the winding speed of the winding portion of the double-twisted yarn spindle 10 is different for each adjacent weight, the drive source of the extending portion is provided independently for each weight, so that the detection sensor 72 stores The increase / decrease in the storage amount of the drum 70 is sensed, and based on the sensed signal, the drive motor 71 and the stretching roller drive motor 74 are controlled independently for each weight through the control device 73. The strip can be wound under optimum conditions according to its type and fineness.

[0019]

[Effects] The present invention, when two or more yarns having different shrinkage properties are combined as described above, each yarn is independently and preliminarily stretched or relaxed. Thread
After that, since the twisting and winding is performed, an appropriate tension is positively applied to each yarn having different shrinkability, as compared with the conventional one in which the yarn is mixed through a simple tension adjusting device. Since they can be applied and aligned and aligned, the combined yarn can have a uniform appearance, and can be stably combined and twisted in response to changes in yarn type, fineness, and spindle speed.
Moreover, the conventional stretching step and ply-twisting step which are performed in two independent machines can be performed by a single machine according to the present invention, which is useful for shortening the steps. In the case where the yarn supplying creel portion is arranged on one side and the stretching portion and the winding portion are arranged on the other side, the height of the machine stand is not so high, and the operability is extremely good for the operator, and the work efficiency is remarkably improved.
