BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fleece guide disposed between a back detaching roller and a front detaching roller in a comber.

[0002]

2. Description of the Related Art Conventionally, such a fleece guide is horizontally mounted between a back detaching roller 6 and a front detaching roller 7 and between brackets 3 fixed to left and right roller stands 2 as shown in FIGS. I am doing it. The fleece guide 10A is provided with an ear guide portion 12A that protrudes inwardly into a corner to guide the ear portions 20a at the left and right ends of the fleece 20 fed from the back detaching roller 6, and an ear guide surface 13A of the ear guide portion 12A. A lower surface guide portion 14A having a lower surface guide surface 15A whose upper surface continuously guides the lower surface of the fleece 20 over the entire length in the left-right direction is provided. The rear end surface 10a of the fleece guide 10A is located in front of the line L connecting the outer peripheral front edge of the back detaching roller 6 (in the direction of arrow Z in FIG. 6), and a position substantially in front of the free snip point 18 of the back detaching roller 6. The lower guide surface 15A starts from.

[0003]

In the comber, the fleece 20 combed by the comb cylinder is overlapped with the previous fleece 20 projecting backward from the back detaching roller 6 when the nipper device moves forward, and piecing is performed.
The back detaching roller 6 and the front detaching roller 7 are normally rotated (arrow A in FIG. 1) to feed the fleece 20 forward. The fleece protruding from the nipper device at the time of this piecing is a phenomenon in which the fibers 50 at the front end portions of the widthwise both end portions 20a spread outward in the width direction due to the action of the air flow due to the forward movement of the nipper device (shown in FIG. 2).
Can be seen. In this way, the rear fleece 20 has the ears 20
a When the front end portion is expanded outward, it is pierced by the preceding fleece 20 and is advanced forward from the back detaching roller 6, so that the expanded fiber 50 is separated from the preceding fleece 2.
It is not vertically overlapped with 0 and is extremely easy to bend as compared with the above-mentioned fleece 20 which is vertically overlapped. This fiber 50
According to the fleece guide 10A, since the gap between the nip point 18 and the lower surface guide portion 14 is wide, the bottom roller 6a of the back detaching roller 6 is drawn downward by the accompanying airflow due to the forward rotation, and as shown in FIG. In addition, there is a problem in that it hits the rear end surface 10a of the lower surface guide portion 14 and bends in a hook shape, disturbs the ear portion 20 and deteriorates the quality of the fleece 20.

[0004]

This invention aims at obtaining a fleece guide for preventing the disturbance of the ears of the fed fleece, and is provided between the back detaching roller and the front detaching roller of the comb, In a fleece guide including an ear guide portion that guides the ear portion of the fleece sent from the detaching roller, and a lower surface guide portion that guides at least the lower surface of the ear portion of the fleece, the lower surface guide portion is provided in front of the outer circumference of the back detaching roller. It is characterized in that it has a shape protruding from the edge toward the nip point side of the back detaching roller.

[0005]

[Function] Most of the accompanying airflow due to the forward rotation of the bottom roller of the back detaching roller is controlled by the upper surface of the lower surface guide portion protruding to a position close to the nip point, and is directed forward, so that the airflow is detached. The ears of the fleece that the roller pulls out are guided forward and not pulled downward.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIGS. Since the fleece guide 10 of the present invention is symmetrical on both sides of the fleece 20 in the width direction, only one of them will be described. A roller stand 2 is fixed on the frame 1, and a bracket 3 is fixed on the upper surface of the roller stand 2. The bracket 3 has a protruding portion 4 protruding from the roller stand 2 toward the inner side of the fleece 20 in the width direction, and a mounting portion 5 of the fleece guide 10 is protrudingly provided on the lower surface of the protruding portion 4. A bottom roller 6a of the back detaching roller 6 and a bottom roller 7a of the front detaching roller 7 are supported on the roller stand 2 so as to rotate in the forward and reverse directions by a drive from a drive source (not shown). Further, the respective shaft ends of the top roller 6b of the back detaching roller 6 and the top roller 7b of the front detaching roller 7 are rotatably fitted to the bearing sleeve 8, and the bearing sleeve 8 is provided in the bracket 3 in the vertical direction. It is fitted in the groove 3a so as to be movable up and down. These bearing sleeves 8 are urged downward by a pressure arm 9 to press the top rollers 6b, 7b against the bottom rollers 6a, 7a with a predetermined pressing force.

The fleece guide 10 has a base 11 having a substantially octagonal cross section, and the fleece direction portion of the base 11 is formed in the ear guide 12. The ear guide portion 12 has an ear guide surface 13 that guides and aligns the side of the ear portion 20a of the fleece 20, and the ear guide surface 13 forms an arc surface as shown in FIG. A lower surface guide portion 14 is provided to project inward from the lower portion of the base portion 11 by a predetermined length. The upper surface of the lower surface guide portion 14 is formed as a lower surface guide surface 15 that supports the lower surface of the ear portion 20a of the fleece 20 from below.

A mounting rod 16 is integrally planted on the base portion 11 outward in the width direction, and the mounting rod 16 is mounted on the mounting portion 5.
Of the back detaching roller 6 and the top roller 6 of the back detaching roller 6 in this state.
It is designed to enter the direction of the nip point 18 of the fleece by the back detaching roller 6 from the line L connecting the outer peripheral front edges of b. In addition, behind the back detaching roller 6 (on the right side in FIG. 1), a cushion plate 31, a nipper 32 for sandwiching a fleece with the cushion plate 31,
Feed roller 3 rotating on the cushion plate 31
A nipper device 30 composed of 3 and a top comb 34 is provided so as to swing back and forth. Reference numeral 35 is a combing cylinder.

According to such a configuration, the nipper device 30
When the nipper 32 is retracted, the nipper 32 holds the fleece 20 before combing with the cushion plate 31 and combs the tip of the fleece protruding forward from the cushion plate 31 with the combing cylinder 35. The grip of the fleece 20 is released, and the feed roller 33 feeds the fleece 20 and pieces the rear end of the fleece 20 that projects rearward from the nip point 18 of the back detaching roller 6.
When the nipper device 30 moves forward, the ears 20a of the fleece 20 projecting from the cushion plate 31 spread outward due to the influence of the air flow, pierce in that state, and are forwardly fed by the forward rotation of the back detaching roller 6.

At this time, the accompanying airflow due to the normal rotation of the bottom roller 6a of the back detaching roller 6 is in the vicinity of both ends of the bottom roller 6a, that is, the ears 20a of the fleece 20.
In the portion corresponding to, since the rear end of the lower surface guide portion 14 of the fleece guide 10 is located closer to the nip point 18 than the line L, most of it is deflected forward along the lower surface guide surface 15. It Therefore, the ears 20 of the fleece 20
The fibers 50 that have spread outwards at a will ride on this air flow and smoothly travel forward, preventing them from bending downward. The fibers 50 thus sent out forward are aligned by the ear guide surface 13. At this time, in the present embodiment, the ear guide portion 12 also projects to a position close to the nip point 18, so that the ear aligning action has the nip point 1
Since it is carried out immediately after passing through 8, the ears 20a can be aligned more neatly.

In FIG. 4, the cross section of the fleece guide 10 has a shape corresponding to that of the back detaching roller 6 described above, the front detaching roller 7 direction portion is deleted, and the lower surface guide portions 14 of the left and right fleece guides 10 are removed. Shows a continuous one in the width direction of the fleece similar to that described in the prior art. It is preferable that the lower surface guide portion 15 is continuous in the width direction as described above, because the middle portion of the fleece can be supported from below, but the middle portion of the fleece is surely overlapped vertically as described above, and the back de- vice is secured. Since the influence of the accompanying air flow of the touching roller 6 is almost negligible, the object of the present application can be achieved if the lower surface guide portion 14 has at least a portion corresponding to the lower surface of the ears of the fleece.

[0012]

As described above, according to the fleece guide of the present invention, when the fleece from the nipper device is pierced into the previous fleece and is fed forward from the back detaching roller, it corresponds to at least the ears of the fleece. At the position, most of the accompanying airflow due to the normal rotation of the back detaching roller can be diverted in the direction along the upper surface of the lower surface guide portion that is projected close to the nip point. Therefore, before the piecing, when the fleece at the front end of the ear portion spreads outward, when the fleece is pierced by the previous fleece and sent out from the detaching roller, the fiber spreading outward is forwarded by the deflected airflow. It is possible to guide, and it is possible to prevent bending of the ears and improve quality.
