Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collector used in a spinning machine, and more particularly to a core-guided collector suitable for spinning a core yarn spun yarn.

[0002]

2. Description of the Related Art Generally, in a ring spinning machine, a roving of short fibers to be supplied is drafted, the resulting fleece is sent out from a front roller, and the fleece is twisted by rotation of a spindle rotating at a high speed. It is a spun yarn that is wound around a wood tube that is inserted into a spindle through a snell wire and a traveler on a ring.

The core yarn spun yarn is a yarn obtained by supplying a core (core yarn) made of another fiber to the center of the fleece and winding the fleece around it in a sheath shape to combine them. Alternatively, there is also one in which the core is supplied by twisting while being fed from the side of the fleece described above. A filament yarn is usually used as the core.

In manufacturing such a core yarn spun yarn, it is important to supply the filament yarn or the like to be the core to the fleece of the spinning machine at an accurate position.

FIG. 5 is a view showing a front roller portion of a conventional spinning machine for producing a spun yarn of core yarn. FIG. 5 (a) is a view of the front rollers 1 and 2 as viewed from the rear side in the traveling direction of the fleece. b) is a side view. 1, 2,
Is a front roller, 1 is a bottom roller, and 2 is a top roller. The bottom roller 1 is made of quenched steel and has a thick portion 1a that comes into contact with the top roller 2. The surface of this portion is a fluted roller having a large number of grooves 1b formed in a direction parallel to the axis of the roller. Has become. The top roller 2 has a rubber layer 2b wound around a steel cored bar 2a so that the fleece 3 can be firmly nipped between the groove 1b of the bottom roller 1. Fleece 3
This is the result of adding draft to the roving between the back roller (not shown) and the apron and between the apron and the front roller, and the short fibers are arranged in a substantially parallel state.

A hanging type collector 4 is disposed between the bottom roller 1 and the top roller 2. The collector 4 is usually made of plastic and has a large through hole 4a in the center. A fleece groove 4b through which the fleece 3 passes is formed below the through hole 4a so as to communicate with the through hole 4a. By passing the fleece 3 through the fleece groove 4b, both sides of the fleece 3 are arranged so as not to be disturbed.

[0007] The core 5 is pulled out from a package of the core in a creel (not shown) above the spinning machine, while being properly tensioned through a guide such as a snell wire or a tension device. Then, after passing through the through hole 4a of the collector 4 and being supplied to the center of the fleece 3 at the nip point N between the bottom roller 1 and the top roller 2, after exiting the front roller, twisting by the spindle causes The fleece 3 is wound in a sheath shape to form the core yarn spun yarn 6.

Here, the fleece 3 passes through the fleece groove 4b of the collector 4, while the core 5 is supplied from a different direction (upper side in the figure) from the fleece 3 and needs to overlap the center of the fleece 3. There is. Therefore, the position at which the core 5 is supplied is adjusted so that the core 5 overlaps with the center of the fleece 3. Further, since the core 5 is supplied from above,
As shown in FIG. 5B, the upper edge X of the through hole 4a of the collector 4 is rubbed and passed.

When the fleece 3 and the core 5 pass through the same positions of the front rollers 1 and 2, the fleece 3 and the core 5 come into contact with the same position of the top roller 2 and wear the rubber layer 2b locally. become. Therefore, in a spinning machine, the fleece 3 is normally traversed in the axial direction of the bottom roller 1 so that the contact position of the top roller 2 is changed.
In addition to the traverse, the fleece 3 itself may meander slightly. Therefore, the collector 4 can move along with the traverse and meandering of the fleece 3,
It is supported by a wire 7 and can freely move in the axial direction of the front rollers 1 and 2.

However, according to the above prior art, the core 5
It takes time to adjust the position of so that the core 5 overlaps the center of the fleece 3. Also, even if you adjust the bending angle,
Since the fleece 3 is traversing or meandering as described above, the core 5 cannot follow this. Therefore, there is a problem that the quality of the spun core yarn spun yarn 6 is not uniform.

Further, since the core 5 runs at the same position of the collector 4, the upper edge portion X is worn and the worn surface is rough, so that the filament yarn is rubbed and damaged, or the tension becomes unstable. There was also a problem such as cutting the core 5.

As a solution to this problem, a hanging type collector as shown in FIG. 6 is known. This collector 8 has the same structure as the collector 4 of FIG.
A feature is that a guide groove 8b for restricting the traveling position of the core 5 is formed above the fleece groove 8a. With such a structure, the core 5 is guided to the center of the fleece 3.

[0013]

However, in the conventional collector with core guide shown in FIG. 6, when a person or an object touches the core 5, the collector may run out of the guide groove 8b, and the core yarn spun yarn 6 Quality becomes unstable.

Further, as shown in FIG. 5B, since the core 5 is supplied from the rear side of the collector (backward in the traveling direction of the fleece), the collector 4 is pressed against the top roller 2 by the tension of the core 5, Adhesion of cotton wool to 4 increases. Further, the core 5 is inserted from the rear side of the collector 4 to the through hole 4a.
It is very difficult to do this work.

The present invention has been conceived from the above facts, and an object of the present invention is to provide a core-guided collector in which a filament yarn as a core can be easily inserted and less dust is attached.

In order to achieve the above object, a collector with a core guide of the present invention has a collector main body portion having a fleece groove through which a fleece serving as a sheath passes, and a guide groove for the core. Has a core guide portion,
The core guide portion is formed integrally with the main body portion, the guide groove is aligned with the fleece groove at the center position, and is open to the front side in the traveling direction of the fleece.

Alternatively, there is a fleece groove at the lower end, a first through hole communicating with the fleece groove at the center, and a collector main body having a small hole at the top through which a hanging wire is inserted, and A core guide portion integrally formed on the upper portion of the collector main body, having a second through hole in the center and a guide groove communicating with the second through hole at the upper end, the guide groove being the center of the fleece groove. It is characterized in that the positions are matched with each other and the core guide portion is opened at the tip.

A guide slope may be formed around the guide groove, or the collector body and the core guide may be integrally formed in a V shape.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a core-guided collector (hereinafter abbreviated as “collector”) 10 of the present invention. 2A is an end view of FIG. 1 viewed from A, and FIG. 2B is an end view of FIG. 1 viewed from B. 3A is a view of the collector as seen from the rear side in the traveling direction of the fleece, FIG. 3B is a view as seen from the front side in the traveling direction of the fleece, and FIG. 3C is a side view. The collector 10 shown in these figures is an integrally molded product made of synthetic resin, and comprises a collector body 11 and a core guide 12
It consists of and.

Since the collector body 11 is arranged between the front roller and the apron, it has a rectangular shape in which both upper and lower ends are thick and the middle is thin, and the first through hole 111 is formed in the center of the rectangle. The fleece groove 112 is formed by opening the lower center of the first through hole 111. The surface of the collector body 11 on the side of the top roller 2 is a cylindrical surface having substantially the same diameter as the outer peripheral surface of the top roller 2. As shown in FIG. 2A, the fleece groove 112 is gradually narrowed toward the front in the traveling direction of the fleece shown by the arrow a, and limits the width of the fleece. A small hole 113 penetrating left and right is formed in the upper thick portion, and a wire 13 for suspending the collector 10 is inserted therein. The collector 10 inserted through the wire 13 is movable in the length direction of the wire 13 as described in the conventional example.

The core guide portion 12 is the collector body portion 11.
It is based on a slightly smaller substantially rectangular plate-like portion 121. The plate-shaped portion 121 is inclined with respect to the collector body 11, and as shown in FIG. 3C, the plate-shaped portion 121 is generally in a V shape when viewed from the side. This shape is the top roller 2
It conforms to the shape of. A second through hole 122, which is smaller than the first through hole 111, is formed in the center of the plate-like portion 121, and a guide groove 123 is formed in the upper center of the second through hole 122 so as to coincide with the center of the fleece groove 112. Is cut open. The width of the guide groove 123 is larger than the diameter of the core 5 and is linearly formed from the tip of the plate-shaped portion 121 to form the second groove.
It reaches the through hole 122. Also, this guide groove 123
On both sides of the ribs 124, which are erected on the plate-like body 121,
124, and the distance between these ribs 124, 124 is
It matches the width of the guide groove 123. The rib 124 extends downward from the straight portion of the guide groove 123 and surrounds the upper side and the left and right sides of the second through hole 122. Also, FIG.
As shown in (b) and FIG. 3 (b), guide slopes 125, 125 are formed on both sides of the guide groove 123 of the plate-like portion 121.

FIG. 4 is a diagram showing a usage state of the collector 10 of the present invention. (A) is the figure which looked at the front rollers 1 and 2 from the back side in the advancing direction of a fleece, and (b) is a side view. In the configuration of each part, the same parts as those in the conventional example are denoted by the same reference numerals, and the description will be made focusing on the differences. The roving is the fleece groove 11
The front rollers 1 and 2 of the front rollers 1 and 2 are gripped at the nip point N between the top roller 2 and the bottom roller 1, and a draft is added to form the fleece 3.
It is sent out from 2. As in the conventional example, the core 5 is laid on the fleece 3 and twisted to form the core yarn spun yarn 6.

The core 5 made of filament yarn is supplied from the direction shown by the arrow b in the upper part of FIG. 4, and its tip is inserted from the side of the rotating top roller 2 toward the nip point N. The inserted core 5 is sandwiched between the top roller 2 and the bottom roller 1 to start traveling,
Since tension is applied to the core 5, the core 5 slides on the guide slope 125 and is automatically introduced into the guide groove 123, and overlaps the fleece 3 at the nip point N. The core 5 that has entered the guide groove 123 is held in the guide groove 123 by the ribs 124 on both sides and runs. Since the centers of the guide groove 123 and the fleece groove 112 coincide with each other, the core 5 can surely enter the center of the fleece 3. The shape of the collector 10 is a V shape matching the shape of the top roller 2, and the ribs 12 on both sides are formed.
Since there are 4, 124, it is possible to prevent the core 5 from coming off the guide groove 123.

The conventional core 5 is fed from the rear side of the collector 10 (backward in the traveling direction of the fleece 3) in FIG. 4 (b). Therefore, when tension is applied to the core 5, the collector 10 is pressed against the top roller 2 and there is a problem that the occurrence of fly cotton increases. In contrast,
In the collector 10 of the present invention, the guide groove 123 has the fleece 3
Since it is opened to the front side (or the top roller 2 side) in the traveling direction, the collector 10 is no longer pressed against the top roller 2 and the occurrence of fly dust is reduced.

Further, when the fly dust is generated, it is conventionally accumulated in the first through hole 111 of the collector body 11 and it takes time to remove it. However, in the present invention, the guide groove 123
Since the fly cotton accumulated in the periphery is reduced, and moreover, it is accumulated in the second through hole 122 above the collector 10, it becomes easy to remove it by a blow cleaner of a spinning machine.

The core 5 is sandwiched between the ribs 124, 124 from the left and right. However, since the width between the ribs 124, 124, that is, the width of the guide groove 123 is larger than the diameter of the core 5, the core 5 is usually ribbed. Almost no contact with 124. However, since the fleece 3 traverses as described above, the collector 10 accordingly traverses, and at that time, the core 5 makes light contact with the ribs 124, 124 on both sides and travels while the position is corrected. . Conventionally, the core 5 traveled while rubbing the guide groove 8b in a state where tension was applied, but the contact pressure between the core 5 and the rib 124 of the present invention is much lower than in the conventional case. So there is rib 1
24 wear is reduced. This is due to the structure in which the guide groove 123 is open on the tip side (top roller 2 side) of the core guide portion. In particular, like the guide groove 123 of the illustrated embodiment, if the front end is opened and the rear end is opened to the second through hole 122 and has a slit-like structure that penetrates, the rear side will not rub.

Further, in the conventional collector 4, it was necessary to insert the core 5 into the through hole 4a from the rear side of the collector 4, but in the collector 10 of the present invention, the core 5 is inserted into the collector 10.
Can be supplied from the front side of. Therefore, as described above, by inserting the core 5 from the side of the top roller 2, the core 5 can be automatically inserted into the guide groove 123, and the insertion work of the core 5 becomes very easy.

[0027]

As described above, the collector with a core guide according to the present invention is formed by integrally forming a core body and a collector main body portion having a fleece groove through which a fleece serving as a sheath passes. Since the guide groove for guiding is configured such that the center position of the guide groove coincides with that of the fleece groove and is open to the front side in the traveling direction of the fleece, the core can be inserted from the front side of the collector. , The core can be easily inserted. Also, since the center of the guide groove and the center of the fleece groove are the same,
The quality of the core yarn spun yarn can be stabilized. Further, since the collector is not pressed against the top roller, it is possible to reduce the adhesion of the cotton wool to the collector.

If the core guide portion is formed integrally with the collector, the second through hole is formed therein, and the guide groove is formed in the second through hole, even if the cotton wool collects, it can be easily removed. Become.
