Description

[Detailed Description of the Invention] This invention relates to an improvement of a cocoon fluff removal device using a brush method.

Conventionally, a belt-type fluff removal device as shown in FIG. 1 has been used to remove fluff from cocoons. This device uses cocoons M that are extruded from the bamboo shoots with a knot, etc.
The fluff is sequentially transferred to form a large number of horizontal grooves (grooves extending in the width direction) on the surface, and when it comes into contact with the extraction belt 2 moving in the direction of the arrow, the fluff is drawn in from the fluff inlet 5. . This fluff has small irregularities formed on its surface and is wound onto the winding belt 3 moving in the direction of the arrow. The cocoon M that has been fluffed in this way
are configured to be sequentially pushed out to the right from the chute 4.

Therefore, if the two rollers 6 and 7 that make up the fluff inlet 5 are pressed together as strongly as possible, the fluff can be removed cleanly from the cocoon M, but the belts 2 and 3 meander and their adjustment is difficult. It is complicated and the belts 2 and 3 wear out quickly, so they need to be replaced frequently.

From this point of view, a brush-type cocoon fluff removal device was proposed in place of the above-mentioned belt-type cocoon fluff removal device, but because the fluff pulling action by the rotation of the brush was insufficient, the cocoon could easily separate from the brush. What's worse is that the fluff is not completely removed, and especially the short fluff remains and is discharged, and the cocoon does not easily separate from the brush, causing new fluff to grow. In order to eliminate these drawbacks, increasing the wire diameter of the brush or shortening the bristles to strengthen the fluff removal effect will not only damage the cocoon surface but also significantly reduce the workability of the reeling process, resulting in the quality of cocoon silk. This will lead to a decline.

In view of the above, the object of this invention is to provide a simple cocoon fluff removal device that can instantly and cleanly remove all long and short fluff from cocoons.

The gist of this device is that a first lint removing brush roller is disposed below the cocoons being fed from diagonally above, and rotates on the side of the cocoons being fed; a first pressure roller is disposed on the first lint removing brush roller diagonally below the side of the cocoons being fed, and is pressed against the first lint removing brush roller so as to be freely rotatable; a chute is disposed to the side of the first pressure roller, extending diagonally downward to allow the cocoons to slide down; a second lint removing brush roller is disposed at the bottom end of the chute, and rotates in the same direction as the first lint removing brush roller; and a second lint removing brush roller is disposed diagonally below the side of the second lint removing brush roller opposite the side of the cocoons sliding down.
A second pressure roller is disposed in pressure contact with the lint removing brush roller and is rotatable. The second pressure roller is disposed obliquely above the second lint removing brush roller.
The cocoon fluff removing device is configured as follows: a pressure plate is arranged with a gap approximating the size of the cocoon sliding down between it and the second fluff removing brush roller; and a fluff drawing-in card clothed roller is arranged below the first fluff removing brush roller, which is in contact with the first and second fluff removing brush rollers and rotates in opposite directions.

Hereinafter, embodiments of this invention will be described based on the drawings.

The fluff removing device of the embodiment shown in FIG. 2 is rotatably driven in the A direction on the side from which the cocoons M are sent, and a group of brushes is planted on the outer peripheral surface below the cocoons M that are sent from diagonally above. A first fluff removing brush roller 11 is provided.

Diagonally below the side of the first fluff removing brush roller 11 from which the cocoons M are sent, there is a rotatable first pressure roller 21 which is formed of a tube or rod of the same diameter with a smooth outer circumferential surface. It is disposed in pressure contact with the fluff removing brush roller 11. The first pressure roller 21 is strongly pressed by a pressing means (not shown) to the extent that the tips of the brush groups of the first fluff removal brush roller 11 are curved. Note that the first pressure roller 21 is rotated in the direction A by rotation of the first fluff removing brush roller 11.

A chute 17 is provided on the side of the first pressure roller 21 and extends diagonally downward to slide down the cocoon M from which long fluff has been removed by the first fluff removing brush roller 11 and the first pressure roller 21.

At the lower end of the chute 17, like the first fluff removing brush roller 11, a group of brushes is installed on the outer peripheral surface, and a second fluff removing brush is rotatably driven in the C direction, which is the same direction as the first fluff removing brush roller 11. roller 1
2 are arranged.

A rotatable second pressure roller 22 that is pressed against the second fluff removing brush roller 12 is disposed diagonally below the second fluff removing brush roller 12 on the side opposite to the side from which the cocoon M slides down. , this second
Like the first pressure roller 21, the pressure roller 22 is formed of a tube or rod of the same diameter with a smooth outer peripheral surface, and the tip of the group of brushes of the second fluff removal brush roller 12 is It is placed so that it is pressed tightly to the extent that it is curved. In addition,
The second pressing roller 22 is rotated in two directions by the rotation of the second fluff removing brush roller 12.

In addition, a gap is provided diagonally above the second fluff removing brush roller 12 and has a gap that approximates the size of the cocoon M sliding down. A pressing plate 18 made of thin metal is provided to press against the removing brush roller 12 side. This pressing plate 18 has a rounded bent part formed at the tip of the lower end, and a notch of a predetermined depth is carved in this bent part, and depending on the size of the cocoon M, a cutout is formed in the direction of the arrow. It is arranged so that it can be moved.

Then, below the first fluff removing brush roller 11, a metal clothing is planted on the outer circumferential surface, and it touches the first and second fluff removing brush rollers 11 and 12 so as to intertwine with each other, and moves in the opposite direction E direction. A cloth roller 13 for drawing in fluff is provided which is rotationally driven.

Below the fluff drawing cloth roller 13, there is a self-discharging roller 14 which is rotatably driven and has a metal cloth implanted in a part of the outer peripheral surface, for example, in an area corresponding to about one-fourth of the circumference. , and the cloth roller 13 for drawing in fluff are disposed so as to intertwine with each other. This self-discharging roller 14 is configured to periodically swing in the left and right directions.

On the side of the self-discharging roller 14, a fixed clothing support 16, which has a group of clothing planted on its arc-shaped inner surface, is interlocked with the self-discharging roller 14, which swings periodically in the front and back directions. They are arranged so that they are in close contact with each other. This fixed clothing support 16 is removably attached to a machine frame (not shown).

Next, the operation of the cocoon fluff removing device constructed as described above will be explained.

First, when the cocoon M sent from diagonally above hits the first fluff removal brush roller 11, its long fluff gets entangled with the brush group and is sandwiched between the first fluff removal brush roller 11 and the first pressure roller 21.
At this time, the brush group of the first fluff removing brush roller 11 rotating in the A direction is curved by the first pressure contact roller 21 rotating in the B direction,
The space above the contact area between the brush tip and the pressure roller 21, which has a generally triangular cross section, becomes smaller, and the brush tip comes into contact with the cocoon M up to the base of the fluff, and the area sandwiched between the brush tip and the pressure roller 21 approaches the cocoon M. As a result, the action of drawing in the fluff becomes stronger.
Therefore, the long fluff encasing the cocoon M transferred after decocooning is instantly wound up by the first fluff removal brush roller 11.

Next, the cocoon M with short fluff remaining slides down on the chute 17 and attempts to pass through the gap between the fluff removal brush roller 12 and the pressing plate 18 which are rotating in the direction C while rotating. However, as described above, this gap is adjusted to approximate the size of the cocoon M, and the cocoon M entangles its fluff with the second fluff removing brush roller 12, and the cocoon M entangles its fluff with the rotation of the second fluff removing brush roller 12. Accompanied by the second pressure roller 2
It is ensured that the material is fed to the part where it is sandwiched between the material and the material 2 without flying out. Then, the brush group of the second fluff removing brush roller 12 rotating in the C direction is curved by the second pressing roller 22 rotating in the D direction, and the brush group is curved by the second pressure contact roller 22 rotating in the D direction to remove fluff, like the first fluff removing brush roller 11 described above. Since the pulling action of the cocoon M is becoming stronger, the short fluff remaining on the cocoon M is instantly pulled in from the base and wound onto the second fluff-removing brush roller 12. In this way, the cocoon M from which the fluff has been neatly removed is discharged in the direction of the arrow.

The long fluff wound around the first fluff removing brush roller 11 and the short fluff wound around the second fluff removing brush roller 12 are both rotating in the E direction. It is drawn into the fluff drawing clothing roller 13, then through the self-discharge clothing roller 14 which is swinging in the front and back directions, and is drawn into the fixed clothing support 16, where it becomes fluff 19 below. are deposited sequentially.

In addition, if the distance between the axial center of the brush roller 12 for fluff removal and the axis of the pressure roller 22 is made as small as possible, that is, if the pressure roller 22 with a small diameter is used to strongly press the fluff, the fluff with a shorter length can be removed even further. It has been confirmed that it can be completely retracted into the brush roller 12.

As described above, in the cocoon fluff removal device of this invention, the fluff removal brush roller and the pressure roller that is brought into pressure contact with the brush roller and curves the brush group are provided in two stages, upper and lower, via a chute. Therefore,
At each stage, the brush group of the fluff removal brush roller is curved by the pressure roller, so that the space above the contact area between the fluff removal brush roller and the pressure roller, which has an approximately triangular cross section, becomes smaller, and the tip of the brush becomes a part of the cocoon hair. Because the brush contacts the blade base and the area sandwiched between the brush tip and pressure roller approaches the cocoon,
Since the fluff-pulling action is strong, and since the fluff-removing brush roller and pressure roller, which have a strong fluff-pulling action, are arranged in two stages (upper and lower), the long fluff can be instantly and neatly rolled up in the upper stage. is,
Thereafter, the fluff with short fluff that is difficult to wind up in the lower stage is instantly and easily and neatly rolled up, and in the end, the fluff of the cocoon can be neatly removed.

Moreover, a pressing plate is arranged above the second fluff removing brush roller at the lower stage with a gap approximately the size of the cocoon, and the pressure plate prevents the cocoons sliding down the chute from flying out. In order to reliably remove the fluff, the cocoon can be reliably entangled with the second fluff removing brush roller, and all the cocoons sliding down can be cleanly fluffed.

Therefore, the cocoon fluffing device of this invention eliminates the drawbacks of the conventional brush type fluffing device,
This has the effect of instantly and cleanly removing all the long and short fluff from all the cocoons that are sent.
