Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is a through-type three-strand knotless braiding method that allows the use of a bobbin with a larger strand winding diameter, compared to the conventional three-strand knotless braiding method. The present invention relates to a method and device for braiding twisted knotless nets.

<Prior art and its problems> Conventional three-strand knotless net braiding methods and braiding devices have long been disclosed in Japanese Patent No. 62020, Japanese Patent No. 61518, Japanese Patent No. 124485, etc. As the spindle rotates intermittently to perform braiding, productivity is significantly lower than that of twin-twist knotless nets, which are continuously braided.

Therefore, as a braiding method to eliminate this drawback, for example, Japanese Patent Application Laid-Open No. 58-31148,
There is a method shown in Japanese Patent No. 149595, and there is also a method developed separately by the applicant, but the method used in these methods has a small maximum winding diameter on the bobbin that stores the strands, and there is no seam of the strands. It is not possible to braid long net fabrics, and when braiding long net fabrics, the frequency of replenishing the strands increases, which reduces the operational efficiency of the braiding equipment, and there are The disadvantages include that the knotted net legs of the strands are mixed in, reducing the strength, and that the appearance of the finished product is impaired, reducing the commercial value. This is clear for the following reason. In other words, the conventional example is shown in FIG. 1, and like the conventional example, the spindle wheel shown in FIG. The maximum winding diameter of the bobbin must be equal to or less than the distance connecting adjacent notches with a straight line. This is because bobbins may be located in adjacent notches. Therefore, based on this reasoning, even if the size of the spindle wheel is the same, if the number of notches is reduced, the straight line distance between adjacent notches will be longer, and the maximum winding diameter of the bobbin will be increased by that amount. It becomes possible to increase the The weight wheel shown in FIG. 2 has the same diameter as the six notches shown in FIG. 1, and is provided with four notches.

Expressing these numerically through calculations, if the diameter of the spindle wheel is l, the straight line distance of each notch of the spindle wheel shown in Figure 1 is equal to the radius, so it is 0.5l, that is, the maximum winding of the bobbin. The diameter is also 0.5l. On the other hand, the second
The straight-line distance between each notch on the spindle shown in the figure is approximately 0.7l. Therefore, when comparing spindles with the same diameter, the one with fewer notches allows the maximum winding diameter of the bobbin to be obtained. . Specifically, if we compare the figures in Figure 1 and Figure 2, we will see that the value in Figure 2 is approximately 1.4 times larger, as 0.7l÷0.5l=1.4.

I further considered this in terms of what is shown in Figure 3. In the case shown in Fig. 3, the maximum winding diameter of the bobbin was kept the same as that shown in Fig. 2, and the bobbin was arranged on a spindle wheel having six notches. Then,
Since the maximum winding diameter of the bobbin is 0.7l, the diameter of the spindle is 1.4l, making the entire braiding device larger. In addition, in a spindle wheel with six notches, the time required to open and close the on-off valve required when transferring a bobbin on the adjacent spindle wheel becomes faster, and the rotation of the spindle wheel and the operation of the on-off valve become faster. This makes it difficult to get the timing right and is a factor that prevents high-speed driving.

<Means for Solving the Problems> Therefore, in order to solve the above-mentioned problems, the braiding method and the braiding device for a penetrating three-strand knotless net according to the present invention have a circumferential Five large spindle rings with four notches at the upper half positions are connected in a straight line or in an L-shape, and bobbins with three strands each are placed on the large spindle rings at both ends, and the bobbins are delivered. 1 on the circumference to make
In contrast to the large fortune wheel, which has two notches and which rotate at four times the angular velocity of the large fortune wheel and is connected as described above, the small fortune weight, the large fortune weight, the large fortune wheel, and the large fortune spindle. The wheel is connected in a straight line like the spindle, or the spindle is connected in a straight line like the spindle, or the spindle is connected in a straight line like the spindle. The whole is rotated continuously so that the three strands on both sides cross each other, and four notches are provided in the large fortune wheel to increase the bobbin diameter.

<Example> The example of the braiding method and braiding device for a penetrating three-strand knotless net according to the present invention shown in FIG. 4 is related to the invention described in claims 1 and 2. be. In other words, five Daiun weight wheels 1, 2, 3, 4, and 5, each with four notches for transferring the bobbin at equal positions on the circumference, are connected in a straight line, and the Daiun spindles at both ends are connected in a straight line. Three strands a, b, c and d, e, f forming net legs on weight rings 1 and 5, respectively.
are placed with a 90° phase shift. The large luck spindles 1, 2, 3, 4, and 5 used here are the second
It is the same as shown in the figure. A notch is provided on the circumference for transferring the bobbin, and small spindle wheels 6 and 7 that rotate at four times the angular speed of the large spindle are placed outside the large spindle wheels 1 and 5 at both ends, respectively. Connect so that the whole part is in a straight line.

<Effect of the embodiment> Therefore, the strands a, on the large fortune rings 1 and 5,
After b, c, d, e, and f are rotated the required number of revolutions to braid the net legs, both strands a, b, c, and d are ,e,

Each passes through a small fortune-telling wheel. A known on-off valve is used to transfer the bobbin to the adjacent spindle wheel.

<Example> The example of the braiding method and braiding device for a penetrating three-strand knotless net according to the present invention shown in FIG. 5 is related to the invention described in claims 3 and 4. be. In other words, four of the five Daiun weight wheels 1, 2, 3, 4, and 5 have four notches for transferring the bobbin at equal positions on the circumference. , 3 and 4 are connected in a straight line, and one notch is provided on the circumference for transferring the bobbin with a diameter of one-fourth of the diameter of the large spindle rings 1 and 4 at both ends, and The small luck spindles 6 and 7, which have an angular velocity four times that of the large luck spindle, are connected one each on the connecting line of the four large luck spindles 1, 2, 3, and 4, which are connected in a straight line. Three strands e, d, f constituting a net leg are arranged on the weight ring 4 and used as one twisted ring. In addition, the other end of the large luck spindle 1 connected in a straight line to the remaining large luck spindle 5 is connected at right angles, that is, in an inverted L-shape, and strands a, b, and c constituting the net legs are attached to this. Arrange them with a phase shift of 90°, and use this as the other twisted ring.

<Operation of the embodiment> After the twisting rings 5 and 4 are given the required number of rotations and twisted, the twisting rings 6 and 7 and the large weight wheels 1, 2, 3, and 4 are twisted. While continuously rotating on the ring 5, the pieces are assembled in steps (1) to (13) shown in Fig. 5. During this time, strand e is formed in steps (2) to (3), strand f is formed in steps (4) to (5), strand c is formed in steps (5) to (6), and strand c is formed in steps (9) to (10). ), the strand d becomes (10) to (11)
)
In the step of , each strand a passes through a small spindle.

<Example> Fig. 8 shows each twisted ring 4, 4', 4'', 5, 5',
It shows a serpentine weight arrangement with net legs B, D, F, A, C, and E arranged on 5", net legs A and B, C and D, E and F.
After the net legs B, D, and F move to the left, the net legs D and A, and F and C switch places and complete the required twisting after the knotting. After the twisting is completed, net legs B, A, and C move to the right, and then net legs D and B, F and A, and E and C are exchanged.

FIG. 9 shows a net braided by the serpentine arrangement of weights shown in FIG.

In FIGS. 4 and 5, it is also possible to operate by rotating each spindle wheel in the opposite direction.
