Description

[Detailed description of the invention] The present invention relates to the improvement of a spinning combing machine, and its purpose is to significantly increase the number of needles that act on the raw fibers, thereby improving the combing effect of the raw fibers. .

The needle of a conventional combing machine is an improved thin metal plate called a needle piece type as shown in FIG. 2A. A needle piece 3 is used, in which a large number of needles 2 are formed on the outer periphery (generally eight needles 2), and a needle block 4, in which a large number of needles 2 are stacked and fixed, is attached to the circumferential surface of the cylinder 1. The side-by-side installation was used as a comber machine.

However, in the past, this needle block 4 could only be used to plant needles to the extent that the circumferential surface of the cylinder 1 was only about 100cm thick. Since the fiber 6 was fed once, most of the rotation angle of the cylinder 1 was required to open and close the nipper 5 and feed the raw fiber.

Therefore, one time of combing the raw material fiber 6 becomes insufficient, and in the case of fine wool, it is necessary to repeat the gill and combing operations in the following manner: gill -> comber -> gill -> comber -> gill.

As a general example of this conventional technique, in the case of fine-count wool, the needle blocks 4 are arranged in the circumferential direction on the circumferential surface of the cylinder 1, so that the entire circumferential surface is approximately The strong side is the needle surface, and the gap between the needles 2, that is, the needle pieces 3 in the axial direction in these four blocks is:
From the direction of rotation, the first block is Q, 5mm, the second block is 0.2mm, the third block is 0.05mm, and the final 4th
The block is 0.03mm.

In this way, because the four blocks are allocated to the minimum necessary gap rather than the maximum gap required for that count, the gap difference between each block becomes large, and this difference is drastic because fibers are often cut. This resulted in poor product yield.

In addition, FIG. 2B shows the spacing pieces 7 for determining the gap in the axial direction, and various types of thickness and thinness are used according to the gap difference.

The so-called needle bar set shown in Fig. 2C is a needle bar 8 that has been used for a long time, and consists of a bar 8' with a number of needles 2' hinged in the axial direction at predetermined gaps. The bar 8' is inserted and fixed into an axial groove (not shown) of the cylinder 1, and it is of course possible to implement the present invention using this.

The present invention has a needle-free portion a shown in FIG.
Assume that most of the other half of the circumferential surface is the needle-shaped part, and the needle-shaped part is made of a three-dollar block 4 in which the twenty-one dollar pieces 3 and the spacing pieces 7 are stacked alternately as described above in the direction of rotation. First block 4a, second block 4b, third block 4C...
...Provided on the tenth block 4n and the majority of the circumferential surface.

In the experiment, the size of the conventional comber cylinder 1 and the conventional needle piece 3 were used, and even if ten needle blocks 4 were arranged and fixed in parallel, it was possible to maintain an appropriate needleless part a. Ta.

However, by arranging a large number of needle blocks 4 in parallel in this way, the thickness of the spacing pieces 7 is changed so that the axial pitch of each needle block 4 is made small. It is structured as follows.

For example, in the case of fine wool, the first block 4a is 0.6 mm, the second block 4b is Q, 5 mm, the third block 4C is Q, 4 mm, the fourth block 4d is 0.3 mm, and the fifth block 4e is 0 .2mm 6th block 4f is Q, 1mm 7th block 4g is 0.06mm 8th block 4h is 0.04mm 9th block 41 is Q, Q3mm 10th block 4h is Q, Q3mm The above The axial pitch can be gradually finely divided as shown in FIG.

However, in the case where the needle portion is configured in the majority layer of the cylinder 1 in this way, the comber machine has a camshaft rotated at an appropriate speed by a prime mover (not shown), as illustrated in Fig. 1. Attach the camshaft gear 10 to 9,
Rotation is transmitted via intermediate gear 11 to cylinder shaft gear 12 which rotates cylinder 1, and cylinder 1 is rotated in the direction of the arrow.

In the embodiment shown in the drawings, the camshaft gear 10 has 57 teeth and the cylinder shaft gear 12 has 19 teeth, and the gear system is constructed so that the camshaft 9 makes one rotation for every three rotations of the cylinder 1.

A nipper motion cam 13 is attached to the camshaft 9, and a roller 14 in pressure contact with the nipper motion cam 13 is a roller arm 15.
, nipper motion lever shaft 16, nipper arm lever 17, adjustment rod 18, etc.
It is connected to one end of a nipper arm 20 that is swingably supported by an arm shaft 19, and the upper nipper 5' of one of the nippers 5 is attached to the other end, and the lower nipper 5' is attached to the other end.
The raw material fiber 6 is gripped between the fibers 5'' and released, and the raw fiber is fed once.

However, in the case of the above embodiment, the nipper motion cam 13
The raw fiber 6 of the Nicher 5 is fed once during one rotation of the comber cylinder 1, and the comber cylinder 1 rotates three times during that period.

That is, every three rotations of the cylinder 1, when the needleless part a reaches the nipper 5 position, the combing action is started with the raw fiber 6 being gripped by the nipper 5, and the combing action is started.
When the needleless part a reaches the nipper 5 position after almost one rotation, the combing ends and the nipper 5 moves away from the circumferential surface of the cylinder 1 and both the upper and lower nippers 5' and 5
'' releases the grip, the raw material fiber 6 is fed in an appropriate amount, and the nipper 5 is gripped again.

However, during this levering, the cylinder 1 will idle approximately twice, and the nipper motion cam 13 described above is designed in this way.

3 of the cylinder 1 and cam 13 in the above embodiment:
Rotation 1 mainly applies to fine counts, but in the case of relatively large counts, for example, rotation from the first block 4a to the seventh block 4g
In the case where sufficient combing is achieved by turning the combing, the needleless portion a becomes relatively large, so the ratio of 3:1 is reduced to 2:1.
Of course, it is possible to change the gear ratio and the design of the cam 13 so that Most preferred.

To change the pitch in the axial direction of each of the blocks 4a to 4n, the thickness of the spacing piece 7 can be changed, and the same needle 2 of the needle piece 3 can be used.

In this way, according to the present invention, almost the entire circumference of the comber cylinder can be used effectively, so combing is performed using 2 to 3 times as many needles as in the conventional method, greatly improving the combing effect, and reducing the number of needles. Since the pitch in the axial direction gradually becomes finer, it acts on the raw material without strain.

That is, in the first to third blocks, the raw material fibers are first made completely parallel, and then they are gradually divided into fine fibers to remove impurities from the raw material, thereby minimizing fiber breakage and improving the yield.

In experiments, the yield was improved by about 1 to 3% with wool.

Furthermore, the yield was further improved when the gill process, which is the previous process, was simplified.

Furthermore, since combing is performed with 2 to 2.5 times as many needle rows as in the past, the load on the needles in each row is significantly reduced, and especially in the relatively narrowly spaced needleless sections, the material under tension is combed by an appropriate amount. Therefore, there is less damage to the needles, clogging of the needle amount is reduced, and the durability of the needles and the efficiency of combing are increased.

In addition, since the pitch difference in the axial direction of the needle is gradually divided into multiple stages, it is possible to make the initial pitch relatively large, and therefore there is less resistance to the raw material gripped by the nippers, and the needle The raw material is not forcibly pulled out from the nipper, preventing the so-called raw material flow phenomenon, and the experimental effect is that the initial process of gill -> comber -> gill is eliminated without the need for the above-mentioned repeated operations. I achieved my purpose.

Moreover, according to the present invention, a conventional comber machine can be easily modified by modifying some parts such as gears and cylinders, and the high efficiency described above can be obtained.
