[0002]

BACKGROUND OF THE INVENTION Raw silk such as cotton, staple fiber, hemp and rayon is
The surface of the thread has fine fluff, but when the fluff on the surface of this thread is burnt, the surface of the thread becomes smooth, and the surface of the cloth woven with this thread becomes glossy and shiny. Such a texture occurs. A conventional fluffing device that mechanically performs this fluffing process will be described. FIG. 5 is a schematic perspective view of a conventional yarn fluffing device. As shown in the same figure, this conventional yarn fluffing device includes a winder W and a fluffing mechanism 110.
It is composed of The winder W is a known device,
It comprises a grooved drum 1, a holder 2, a tray 3, a yarn guide 4, a yarn guide 5, a tensioner 6, a slab catch 7, and a housing 9. The grooved drum 1 has grooves formed on the circumferential surface of the drum and guides the yarn to the left and right when rotated. The holder 2 is a rotary shaft for winding the yarn y, and the tray 3 is a raw-feed side raw yarn 8 on which raw yarn is wound.
Is for placing. The yarn guides 4, 5 and the slab catch 7 are for guiding the yarn,
The tensioner 6 is for always keeping the tension of the yarn y constant. The fluffing mechanism 110 is arranged between the yarn guide 4 and the yarn guide 5 of the winder W, has a fluffing box 102 and a gas pipe 101 connected thereto, and fluffs the fluffing mechanism via the gas pipe 101. box
Gas is supplied to the injection holes of 102. This fluffing mechanism 110
The fluffy box 102 is cylindrical and this fluffy box
The yarn y can pass through the hollow portion of 102. This fluffy box
Many injection holes are formed on the inner side surface of 102,
All of these injection holes communicate with the gas pipe 101, and a flame can be injected from the injection holes of the fluff burning box 102. 103 is a slit for passing the yarn y through the hollow portion of the fluffy box 102.

With the above-mentioned structure, the conventional fluffing device operates as follows to burn off the fluff on the surface of the yarn y. While the yarn y fed from the yarn supplying side original yarn 8 is wound up as a large package P by the winder W, the yarn y is fed to the yarn guide 4, the fluffing box 102 of the fluffing mechanism 110, the yarn guide 5, the tensioner 6, The slab catch 7 and the grooved drum 1 travel.

FIG. 1 is a schematic perspective view of the fluffing apparatus of this embodiment. As shown in the figure, the fluffing device of the present embodiment is provided with a fluff raising mechanism 30 for moving the yarn y while contacting it, and a position for burning the fluff of the yarn y after passing through the fluff raising mechanism 30. The feature is that the fluffing mechanism 40 is provided. The fluffing apparatus of the present embodiment includes a winder W, a fluff raising mechanism 30 for moving the yarn y while making the yarn y contact, and a fluff arranged at a position for burning the fluff of the yarn y after passing through the fluff raising mechanism 30. A baking mechanism 40 and a drive mechanism 10 for driving the fluff raising mechanism 30.
It is composed of The winder W is a known device,
It is substantially the same as the winder of the conventional fluffing processing equipment,
It is composed of a grooved drum 1, a holder 2, a tray 3, a yarn guide 4, a yarn guide 5, a tensioner 6, a slab catch 7, and a casing 9. The grooved drum 1 has grooves formed on the circumferential surface of the drum and guides the yarn to the left and right when rotated. The holder 2 is a rotary shaft for winding the yarn y, and the tray 3 is a raw-feed side raw yarn 8 on which raw yarn is wound.
Is for placing. The yarn guides 4, 5 and the slab catch 7 are for guiding the yarn,
The tensioner 6 is for always keeping the tension of the yarn y constant. The yarn y fed from the yarn feeding side original yarn 8 is in the order of the yarn guide 4, the fluff raising mechanism 30, the fluff firing mechanism 40, the yarn guide 5, the tensioner 6, the slab catch 7, the grooved drum 1, and the holder 2. It is passed. It should be noted that the yarn y may be any type of raw silk with a fluffy surface, such as cotton, staple fiber, hemp, and rayon.

FIG. 2 shows a fluff raising mechanism 30 and a fluff burning mechanism 40.
Is a plan view, FIG. 3 is a front view thereof, and FIG. 4 is a side view thereof. As shown in FIGS. 1 to 4, the fluff raising mechanism 30 includes a pair of left and right guide rollers 31, 32 rotatably attached to a pair of left and right support shafts 35, 36 fixed to a column of the housing 9. It consists of The yarn y is wound around the pair of guide rollers 31 and 32 in a figure-eight shape, and the pair of guide rollers 31 and 32 are arranged at positions slightly twisted from each other. Therefore, the yarn y in the front portion wound around either the guide roller 31 or 32 and the yarn y in the rear portion wound around the guide roller travel while contacting each other. In other words, if the yarn y is simply wound around the pair of guide rollers 31 and 32 arranged in parallel in a figure-eight shape, the portion before the guide roller 31 or 32 is wound around. The yarn y and the yarn y in the portion after being wound around the guide roller do not contact each other. With this configuration, the yarn y wound around the guide rollers 31 and 32 of the fluff raising mechanism 30 travels while always contacting,
The effect that the fluff of the yarn y can be caused is exhibited.

As shown in FIGS. 2 and 3, a plurality of circumferential grooves 34 are formed on the circumferential surface of the pair of guide rollers 31, 32 at intervals in the longitudinal direction of the respective guide rollers 31, 32. Has been done. For this reason, the circular grooves of the guide rollers 31, 32 are
The yarn y wound around the 34 in the shape of a figure 8 a plurality of times is hooked in the circumferential groove 34 of the guide roller 31 and always runs in the circumferential groove 34. Does not get tangled. Therefore, the yarn y has an effect that the guide rollers 31 and 32 can be smoothly moved. In addition,
The number of the circumferential grooves 34 of the pair of guide rollers 31, 32 is not particularly limited, and any number may be formed.
The number of 34 affects the degree of fluffing,
About 5 to 15 pieces are desirable, and about 10 pieces are particularly preferable.

Next, an example of winding the yarn y around the fluff raising mechanism 30 is as follows. For example, FIG.
As shown in, first, the yarn y fed from the yarn supplying side original yarn 8
The end of the guide roller 31 is wound around the leading edge of the guide roller 31 from below, the yarn y is wound around the leading edge of the guide roller 32 from below, and again the second from the tip of the guide roller 31. The winding groove 34 is wound from below. Then
The second orbital groove 34 from the tip of the guide roller 32 is wrapped around from below and again the third orbital groove from the tip of the guide roller 31.
Wrap 34 from below. Sequentially, a pair of guide rollers 3
The yarn y is wound between 1 and 32 in the shape of a figure 8 toward the base ends of the guide rollers 31 and 32. Of course, the winding direction of the yarn y around the pair of guide rollers 31 and 32 in the shape of a figure 8 may be opposite to the above-described direction, that is, the guide rollers 31 and 32 may be wound from the base end to the tip. In addition, in the present embodiment, the pair of guide rollers 31 and 32 are arranged on the left and right, but may be arranged not only on the left and right but also on the upper and lower sides, and of course may be inclined, and the arrangement direction thereof Is not particularly limited. As mentioned above, the guide roller is arranged in a slightly twisted position.
It has a very simple structure in which the yarn y is wound into a figure 8 between 31 and 32, so it is very cheap and easy.
The fluff raising mechanism 30 can be developed. Further, it is possible to freely change the contact angle between the yarns y only by changing the twist angle of the pair of guide rollers 31 and 32, and the raising amount of the fluff can be adjusted by changing the contact angle. The traveling speed of the yarn y can be adjusted to prevent the yarn breakage.

As shown in FIGS. 1 to 4, the guide roller 31
A pulley 33 is attached to the base end of the support shaft 35 of
A belt 13 of the drive mechanism 10 described later is wound around this pulley, and when the belt 13 of the drive mechanism 10 travels, the guide roller 31 rotates. The guide roller 31,
Pulleys 37 and 38 are attached to the tip ends of the support shafts 35 and 36 of 32, respectively. Between the pulley 37 of the guide roller 31 and the pulley 38 of the guide roller 32, a belt 39 is formed in an 8-shape.
Is wrapped around. When the guide roller 31 rotates,
The belt 39 travels, and the guide roller 32 rotates in the direction opposite to the rotation direction of the guide roller 31.

Next, the fluffing mechanism 40 will be described. As shown in FIGS. 1 to 4, the fluffing mechanism 40 is arranged at a position where the yarn y after being fluffed by the fluff raising mechanism 30 is baked. This fluffing mechanism 40 has a burner 42 which will be described later.
43, 44 are attached. This fluffing mechanism 40
Since the burner 42 can radiate a flame to burn the fluffed yarn y, the fluffed yarn y can be fluffed.

Moreover, the burner 42 has a cylindrical shape with one end closed, and a plurality of injection holes 41 are formed on the side surface in a row along the longitudinal direction of the burner 42. A flame can be emitted by directing the holes 41 toward the respective contact points T of the yarn y. Therefore, the yarn y immediately after being forcibly fluffed can be baked many times,
The yarn y can be reliably and uniformly baked, and the quality of the fluff-yarned yarn y can be improved. Since it is sufficient to burn the yarn y after the fluffing, the burner 42 of the fluffing mechanism 40 not only burns the contact point T of the yarn y, but also slightly above the contact point T of the yarn y. May be below.

Further, the burner 42 is arranged below the guide rollers 31, 32 of the fluff raising mechanism 30 with the injection hole 41 of the burner 42 facing upward. Because of this, burners
The flame emitted from the injection hole 41 of the guide roller 42
This has the effect that the yarn y traveling between can be reliably baked.

In order to reliably apply the flame radiated from the injection hole 41 of the burner 42 to the traveling yarn y to burn the yarn y, the following measures may be taken. That is, FIGS.
As shown in FIG. 4, a pair of plates 43 and 44 are attached to the front surface of the injection hole 41 of the burner 42 at a position where the flame radiated from the injection hole 41 is sandwiched. Plural slits 45 and 46 are formed in the plates 43 and 44, respectively. As a result, the slits 45 and 46 of the plates 43 and 44 are positioned so as not to touch the traveling yarn y, and the flame is radiated from the injection hole 41 of the burner 42.
It is preferable to burn the yarn because the yarn y can be baked more reliably.

Next, the drive mechanism 10 will be described. Again, as shown in FIG. 1, the drive mechanism 10 has a motor 14 built in the housing 9, and a drum drive pulley 17 and a guide roller drive pulley 21 are coaxially mounted on a spindle of the motor 14. Is attached to. On the other hand, a pulley 15 is attached to the spindle of the grooved drum 1, and a V belt 16 is wound between the pulley 15 and the drum drive pulley 17. When the motor 14 is rotated, the grooved drum 1 rotates. A flat belt 13 is wound around the guide roller drive pulley 21 and the pulley 33 of the guide roller 31 of the fluff raising mechanism 30. 11 and 12 are small pulleys,
This is to prevent the flat belt 13 from coming off from the peripheral surfaces of the guide roller drive pulley 21 and the pulley 33 of the guide roller 31. When the motor 14 is rotated, the guide roller 31 of the fluff raising mechanism 30 is rotated. With this configuration, when the motor 14 is rotated, the grooved drum 1 is rotated,
The guide roller 31 of the fluff raising mechanism 30 rotates in synchronization with the grooved drum 1. When the guide roller 31 rotates, the guide roller 32 rotates in a direction opposite to the rotation direction of the guide roller 31 in synchronization with the guide roller 31. Therefore, when the grooved drum 1 rotates, both the guide rollers 31 and 32 rotate in synchronization with the grooved drum 1. The drive mechanism 10
It suffices to rotate the guide rollers 31 and 32 of the fluff raising mechanism 30, for example, a mechanism in which gears and cams are combined, and various mechanisms can be adopted.

With the above-described structure, the yarn fluffing treatment apparatus of this embodiment operates as follows. As shown in FIG. 1, first, when the motor 14 of the drive mechanism 10 is started and rotated, the grooved drum 1 rotates in the rotation direction indicated by the arrow in the figure, and the fluff is synchronized with the grooved drum 1. The guide roller 31 of the standing mechanism 30 rotates. Of course, when the guide roller 31 of the fluff raising mechanism 30 rotates, the guide roller 32 rotates in the direction opposite to the rotation direction of the guide roller 31 in synchronization with the guide roller 31. By the rotational force of the grooved drum 1 and the guide rollers 31, 32 of the fluff raising mechanism 30, the yarn y fed from the yarn supplying side original yarn 8 is wound as a large package P by the winder W, while the yarn y is a yarn. The guide 4, the fluff raising mechanism 30, the fluff firing mechanism 40, the yarn guide 5, the tensioner 6, the slab catch 7, and the grooved drum 1 travel, and finally, they are wound up as a large package P.

In the fluff erection mechanism 30, the yarn y has a contact point T.
Since the guide rollers 31 and 32 travel in the shape of a figure 8 while making contact with each other, the portions of the yarn y contacting at the contact point T are fluffed. That is, the yarn y can be fluffed mechanically and efficiently without intervention of manual work.

Then, the yarns y running on the fluff raising mechanism 30 run on the leading edge groove 34 of the guide roller 31, and the yarn y comes into contact at the contact point T closest to the front, and the fluff on the surface of the yarn y. Is awakened. The fluffed yarn y is burned from below by the flame radiated from the frontmost injection hole 41 of the burner 42, and is surely fluffed. Then, the yarn y travels in the second circumferential groove 34 from the tip of the guide roller 32, and at the second contact point T from the front, the yarn y portions come into contact with each other to cause fluffing. The fluffed yarn y is burned from below by the flame radiated from the second injection hole 41 from the tip of the burner 42, and is surely fluffed. Sequentially, guide roller
The yarn y is alternately fluffed and fluffed until it runs at the base ends of 31 and 32. Therefore, all the fluff lying sideways along the surface of the yarn y is raised, and the fluff is surely burned and removed. That is, the yarn y is mechanically and efficiently
The effect of raising the fluff on the surface of the surface and reliably firing the fluffed yarn y is obtained. Moreover, since the yarn y is processed by repeating fluffing and fluffing repeatedly, the burning power of the burner 42 may be weak and the gas consumption is small, which is economical. Therefore, the yarn y is gradually fluffed with a weak flame, so that the unevenness of the yarn y is eliminated and the yarn y can be uniformly fluffed.
This has the effect of improving the quality of the fluffy yarn y. Furthermore, high-speed processing with a yarn speed of 800 m / min or more is possible, and the efficiency is very high.

After traveling through the fluff raising mechanism 30 and the fluffing mechanism 40, the yarn y travels through the yarn guide 5, the tensioner 6, the slab catch 7, and the grooved drum 1, and is finally wound up as a large package P.

[0021]

According to the yarn fluffing device of the first aspect of the present invention, fluffing is caused on the surface of the yarn fed from the yarn supplying side original yarn, and the yarn after the fluffing is fluffed. As a result, the fluff on the surface of the yarn can be reliably removed, and the gloss and luster of the cloth woven with the fluffed yarn can be improved, and the texture of the silk can be improved. Claim 2
According to the yarn fluffing device, the yarn can be mechanically and automatically fluffed efficiently, and the simple structure of wrapping it between the pair of guide rollers in the shape of 8 makes it easy. A fluff rising mechanism can be created.
According to the yarn fluffing device of the third aspect, the yarn is processed by repeating fluffing and fluffing alternately and repeatedly, so that the burner may have a low heating power. For this reason, the yarn y is gradually fluffed with a weak flame, so that unevenness in the burning of the yarn is eliminated, the burnt condition of the yarn can be made reliable and uniform, and the quality of the yarn after fluffing can be improved. It can be processed. According to the yarn fluffing device of claim 4, since the flame of the burner is radiated upward to burn the fluffed yarn, the flame does not escape and the burned condition of the yarn can be ensured. The quality of the yarn after being fluffed can be improved by making it uniform.
