Description

[Detailed description of the invention] Industrial application field The present invention relates to a cylinder brush for a comber.
Specifically, the present invention relates to an improvement of a cylinder brush that removes and cleans debris, neps, etc. attached to a combing cylinder using a high comb.

BACKGROUND ART Conventionally, as shown in FIG. 3, a combing cylinder 16 using a high comb has a plurality of rows of needles 17a, 17b provided at a predetermined angular interval in the circumferential direction on a part of the circumferential surface of the cylinder. Moreover, the axial needle gap of each needle row is the same as that of the needle row 1 at the front in the direction of rotation when rotating in the direction of the arrow in the figure to perform the combing action.
The needle row 17b at the rear in the rotational direction is narrower than the needle row 7a. For example, the axial needle gap in the front row is 0.7
In the last row of mm, it is about 0.15mm. The combing cylinder 16 removes short fibers, impurities, etc. by a cylinder brush 10A disposed below the combing cylinder 16.
It is designed to be cleaned to remove dirt, etc. This cylinder brush 10A must be able to penetrate not only the axial needle gap of the forward needle row 17a in the rotational direction of the high comb but also the axial needle gap of the rear needle row 17b to remove and clean debris, neps, etc. Must be.

Therefore, as shown in FIG.
A thin diameter wire 1A and a relatively thick fiber wire 4 such as vegetable fiber to support it are placed in the planting hole 12A.
The mixed hair bundle 7A in which A is mixed is attached to the mold stopper 13A.
A fiber bundle 6A consisting only of a fiber wire 4A such as a vegetable fiber is planted on the other outer circumferential surface. Said wire 1
A and the tip of the fiber wire 4A form the same surface over the entire circumference, and the outer diameter of the cylinder brush is uniform.

Problems to be Solved by the Invention Since the conventional cylinder brush has a uniform outer diameter, when the wire enters the axial needle gap in the rear row of needles of the high comb, it is obstructed by the thick fiber wire. It was difficult to penetrate, and a slight burr remained on the needles of the high comb, which obstructed the brushing action, resulting in insufficient cleaning to remove impurities, neps, etc., and causing the combing cylinder to become clogged with cotton.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a wire bundle consisting of a large number of thin wires planted in a spiral shape on the outer peripheral surface of the core body, and a large number of fibers on the other outer peripheral surface. A fiber bundle made of wire is planted to support the wire bundle, and the wire surface formed by the tip of the wire is slightly smaller than the fiber wire surface formed by the tip of the fiber wire. It is characterized by the fact that it stands out.

In other words, the wire surface formed by the tip of the wire is made to protrude slightly from the fiber wire surface formed by the tip of the fiber wire, so that even if the wire is obstructed by the fiber wire, the high comb will not work. The fiber wire can fully penetrate into the axial needle gap of the rear needle row, and the fiber wire mainly acts on the axial needle gap of the front needle row of the high comb, but the burrs of the needles of the high comb obstruct this action. However, the wire works steadily. Therefore, all the needles of the high comb are thoroughly cleaned to remove short fibers, debris, neps, etc.

Embodiment An embodiment of this invention will be described below based on the drawings.

Fig. 1 shows a row of cylinder brush configurations according to this invention, in which two half rolls 11a and 11b, which are made of metal such as aluminum or essence, are exemplified as core bodies, and the planting holes 12 are arranged in a staggered manner on the outer peripheral surface. It is drilled in. A wire bundle 3, which is a bundle of wires 1 (for example, about 0.08 mm in thickness) that are thin enough to fit into the axial needle gap of the needle row 17b at the rear of the high comb, is implanted in the implantation hole 12 in a spiral shape 8. Plant fibers thicker than the wire 1 (about 0.2 to 0.4 mm thick) are placed in the other planting holes 12.
A fiber bundle 6, which is made by bundling a large number of fiber wires 4 such as the above, is planted so as to support the wire bundle 3.
The planting method is the well-known method described above. A wire surface 2 formed by the tip of the wire slightly protrudes from a fiber wire surface 5 formed by the tip of the fiber wire. The protruding length is several millimeters, but preferably 1.0 to 1.5 mm.
That's about it. Note that the number of spirals may be one or several, and the spiral pitch may also be determined as appropriate.

The half-split rolls 11a and 11b on which the hair bundles have been implanted in this manner are integrally fixed to the rotating shaft 15 of the cylinder brush by screwing them with tightening bolts 14.

As shown in FIG. 2, the cylinder brush 10 formed as described above is placed below the combing cylinder 16 with a gauge of several millimeters, and rotates at a rotational speed of about 3 to 4 times that of the combing cylinder. Rotate in the direction of the arrow to set needle row 1 in front of the high comb.
7a to the rear needle row 17b.

In the brushing action, the fiber wire 4 comes into contact with all the needles of the high comb, and both the wire 1 and the fiber wire 4 enter the axial gap of the needle row 17a at the front of the high comb, and enter the axial gap between the needles of the rear needle row 17b. , only wire 1 got in and there was an obstruction.
Remove nets etc.

At this time, the fiber bundle 6 is attached to the burrs of the needle row 17a in front of the high comb or the needle row 17b at the rear.
When it comes into contact with the needles and bends, the wire bundle 3 supported by this also bends following the fiber bundle 6, but the wire 1, which protrudes slightly from the fiber wire surface 5, is sufficient to fill the gap between the needles. Get into it. Therefore, the cotton that has grown deeply on the burrs of the needles, or the debris, neps, etc. in the axial needle gaps of the rear needle row 17b are sufficiently removed.

Furthermore, since the wire 1 has high hardness, it also acts to quickly eliminate the needle burr itself.

Next, in order to manufacture the wire surface 2 so as to slightly protrude from the fiber wire surface 5, processing is performed in the following order, for example.

(1) The fiber bundles 6 are planted in the planting holes 12 other than the planting holes 12 in which the wire bundles 3 are to be planted in the spiral shape 8.

(2) finishing the outer diameter of the fiber bristle bundle 6 with a known hair trimmer that finishes the outer diameter of the brush with a rotating cutter;
A fiber wire surface 5 is formed.

(3) Wire bundles 3 protruding from the fiber wire surface 5 by a predetermined length or more are planted in a spiral shape 8.

(4) Cut the wire bundle 3 into a predetermined length using the hair trimmer so that the wire surface 2 protrudes slightly from the fiber wire surface 5.

The above can be easily carried out by cutting twice.

Effects of the invention Since the thin wire was supported by a fiber bundle, even a thin wire could act on the combing cylinder, and the tip of this wire was made to protrude slightly beyond the surface of the fiber wire formed by the tip of the fiber wire. Therefore, when the wire bristle bundle follows the fiber bristle bundle and bends, it can fully penetrate into the high comb, and the brushing effect can be improved, especially in the axial needle gap of the needle row behind the high comb and the burr part of the needles. . Furthermore, since the wires are bundled and separated from the fiber bundle portion, even items with steps like this can be easily processed.
