Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fan shear manufacturing device in which plating is wound around the outer periphery of spun yarn in an almost untwisted state. This invention relates to a fan shear manufacturing device for producing bulky fan shear at high speed, making the best possible use of the original texture of the real fibers that make up the yarn.

(Prior art) In general, as a manufacturing method for fansharn that emphasizes the characteristics of the fibers that make up the spun yarn, the spun yarn is untwisted to an almost untwisted state, and a plating yarn is plied on top of it to create the texture of the fiber itself. There are known methods to change the Conventionally, as shown in FIG. 3, a spinning yarn package P1 that is once rewound in a counterclockwise direction is used as a manufacturing device for this fansharn.
is attached to the spindle S1, and the spindle S1 is first rotated counterclockwise as shown by the arrow, and pulled upward through the guide G, and the feed roller is untwisted as much as possible to untwist the yarn. Another package P2 in which the yarn Y is attached to the outer periphery of a hollow spindle s2 in order to impart strength to the yarn Y by winding a plating yarn around the outer periphery of the yarn Y using the yarn Y as a core yarn. A yarn Y2 that will become a plating yarn is pulled out from the cleaning machine, and the pulled yarn is wound around the core yarn from the outer periphery by rotation of a hollow spindle, and then wound around a winding device T via a feed roller F2. I try to take it.

(Problems with the prior art) By the way, in the case of this conventional device, the spun yarn single yarn is generally left twisted (in the Z direction), while the cone winding of the spun yarn is wound clockwise. When untwisting the twist, which is rotated only in the additional twisting direction, untwisting too much may cause the yarn to break due to ballooning formed between the yarn feeding spinning cone P1 and the yarn guide G. occurs, at most 10 to 3 twists of the spun yarn.
Only about 0% untwisting is possible, and in addition, in relation to this balloon tension, the spindle rotation speed is 1000 r, p,
m~200Or, p, mL cannot be raised. Moreover, there is also a drawback that there is a limit to the ability to make the spun yarn soft, which is rich in bulk and takes advantage of the texture of the fibers that make up the spun yarn. SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned drawbacks, and its purpose is to use a cone-wound package that has been wound clockwise without being re-wound counterclockwise, and to create a fan shear with an excellent texture. The purpose is to provide a processing device that can mass-produce products at high speed.

(Means for solving the problem) A false twisting means is provided at the lower part of the hollow spindle device integrally with the hollow spindle. Next, fit rollers are provided below the false twisting means at intervals shorter than the average fiber length of the cone-wound spun yarn mounted on the hollow spindle. Furthermore, downstream of the feed roller, a hollow spindle device to which a plating package for winding the outer periphery of the spun yarn in a substantially untwisted state is mounted, a feed roller, and a winding device are sequentially arranged.

(Function) To explain based on FIG. 1, yarn Y1 pulled upward from the spinning cone package 5 wound clockwise.
Since the package is attached to the outer periphery of the hollow spindle 3 rotating in the Z direction, twisting is applied in two directions, and additional twisting is applied to the yarn Y□. As the thread moves downward, the thread Y1 is twisted in the S direction. Next, the yarn Y1 is pulled out downward through the false twisting means 6.
is rotated to the position of this false-twisting means with substantially the same rotation as the rotation of the cone-wound package 5, and is pulled out to the position of this false-twisting means with almost no untwisting. Immediately after the yarn Y1 passes through the false twisting means 6, it is instantaneously untwisted by the number of rotations of the cone-wound package 5, but is immediately drawn in by the feed roller 13 and passes through the hollow spindle 10, where it is twisted into the hollow spindle 10. The yarn T2 pulled out from the package 12 attached to the outer periphery of the spindle is wound around the outer periphery of the spun yarn Y1 which is almost untwisted in the hollow spindle 10, and then the package 15 is wound by the winding device 14. It is wound up as.

(Example) An example of a device for carrying out the present invention will be explained in detail with reference to the drawings. In FIG. 1, 1 is a hollow spindle device,
The device consists of a hollow spindle 3 rotatably supported by a U-shaped bracket 2. 4 is a belt for driving the hollow spindle 3; 5 is a cone winding package in which spun yarn is wound, which is attached to the upper part of the hollow spindle 3; the cone is wound in a clockwise direction.

Reference numeral 6 denotes a false-twisting means integrally attached to the lower part of the hollow spindle 3, and the false-twisting means is a wear-resistant metal linear body formed in a substantially U-shape as shown in FIG. It is more than that. The false twisting means may also be a known false twisting spindle. This false twisting means 6 and the hollow spindle device make the yarn almost untwisted.

Reference numeral 7 denotes a feed roller provided below the false twisting means, and the distance l between the feed roller and the false twisting means 6 is arranged to be shorter than the average fiber length of the spun yarn of the cone-wound package 5. It is something. Here, the average fiber length of the spun yarn varies depending on the type and count of the fibers, but for example, for cotton 308-40S, it is about 28-32 mm. Reference numeral 8 denotes a spindle device for winding a splicing yarn around the outer periphery of a substantially untwisted core yarn, and this device includes a hollow spindle 10 rotatably supported by a U-shaped bracket 9. 11 is a drive bell l/12 of the hollow spindle 10
1 is a package in which spliced yarn is wound around the outer periphery of spun yarn that is almost in an untwisted state) This package is attached to the upper part of the hollow spindle 10 mentioned above. 13 is a feed roller disposed downstream of the spindle device 8, and 14 is a winding device.

Now, when the hollow spindle 3 is rotated in the Z direction as shown by the arrow by the drive belt 4, the cone-wound package 5 wound with the spun yarn attached to the outer periphery of the hollow spindle 3 is rotated.
also rotates in the Z direction. When the yarn is pulled out upward, the twist between the package 5 and the head of the hollow spindle 3 at the time of release is in the Z direction, and additional twisting is applied to the yarn.

Therefore, even if ballooning occurs due to the rotation of the cone-wound package 5, additional twist is applied to the yarn itself, increasing the strength of the yarn, so that the yarn will not be cut. Next, the yarn Y pulled out from the cone-wound package 5 is pulled out downwardly through the head of the hollow spindle 3, so that the twist is reversed in this hollow spindle and S
When the twist is added, the twist from the false twisting means integrally provided at the lower part of the hollow spindle is propagated, and an S twist is applied. The yarn then passes through a false twisting means 6 and is drawn out by a feed roller 6. At this time, the yarn immediately after leaving the false twisting means 6 is instantaneously untwisted in the Z direction and becomes almost untwisted, but the distance l between the feed roller 7 and the false twisting means 6 is Even if the yarns of the fibers constituting this spun yarn are untwisted in the Z direction and become almost untwisted, the fibers constituting this yarn are entwined with each other and have binding force. Therefore, the spun yarn is not cut during this time. Next, a plating thread, which is a presser thread, is pulled out from another package 12, passes through a hollow spindle 10, and is wound around the outer periphery of the nearly untwisted yarn that has passed through the feed roller 7, and is further wound through the feed roller 13. It is wound up as a package 15 by a winding device 14.

(Effects) As mentioned above, the present invention provides a false twisting means integrally with the hollow spindle at the lower part of the hollow spindle as a means for making the spun yarn in which the plating is wound around the spun yarn almost untwisted. Since the distance between the false twisting means and the feed roller is set to be less than the average fiber length of the spun yarn, compared to conventional devices, the cone-wound package that is wound clockwise can be wound counterclockwise. Since there is no need to rewind and the spindle rotation can be increased without worrying too much about balloon tension, mass production is possible at high speed, and the twist of the spun yarn that becomes the core yarn can be changed to a non-twisted state close to 0. As a result, it is possible to produce bulky and soft fansharn that takes advantage of the characteristics of the fiber.
