Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Field of Application> The present invention relates to an apparatus for manufacturing a braided knotless net.

<Prior art and its problems> A knob containing a strand is attached to a supporting spindle that moves via a point valve on four notches provided in a braided ring that rotates at the same time as a coaxially attached drive gear. , braid the net legs and knots at the tip of the tsum,
In a knotless braiding net knitting device that braids a net fabric having a desired mesh by pulling out the net fabric with a separately provided stitch roller, the braided unit of the knots is simply formed into a straight line or a circular shape. The connected knitting device has a large length or diameter, which increases the equipment area, which not only makes it inconvenient to operate the knitting machine, but also makes it difficult to store the strands in the case of a circular knitting machine. As the tsum becomes longer, the tsum becomes warped, making it difficult for the tsum tip to follow the rotation of the braided ring, which may cause the tsum to break, or the tsum tip to rotate unevenly, causing variations in the tension of the strands that make up the net legs. arise,
There were drawbacks such as a decrease in the strength of the mesh. Therefore, in order to eliminate these conventional drawbacks, the applicant connected the braided rows consisting of the braided units of knots in a serpentine manner, and the strands were connected before and after the transition from one braided row to the other braided row. In order to make the structure of the braided knots the same, we developed an apparatus for producing a braided knotless net, which is equipped with clutches for adjusting the phase of the strands in the uppermost and lowermost braided rings of the braid row. However, with this device equipped with a clutch, it was difficult to find the right timing to operate the clutch in a timely and reliable manner, and there were also problems with the durability of the clutch itself.

<Means for Solving the Problems> The present invention provides an excellent device in which the phase of the strand is changed while continuously operating, instead of the method described above in which the braided ring is stopped by the clutch operation and the phase of the strand is changed. The purpose is to provide the following.

In other words, the present invention provides a knotless braided cord in which a bobbin containing a bobbin wound with a strand is attached to a supporting spindle, and the supporting weight is braided while intersecting the strands through a point valve or groove track. In a knitting net device, three braided rings each having four notches for transferring strands are arranged in a straight line in the horizontal direction to form a pair of two strands having a phase of 180°. One pair of each is arranged in the braided loops at both ends so that the phase is 90°, and the braided units of the net legs are arranged in two stages in the longitudinal direction, and two or three braided loops having these four notches are arranged. The whole is connected in a square shape with 8 or 9 braided loops, and the two pairs of strands on diagonally opposite braided loops in the square connected state are in the same phase. This is used as a braided unit of knitted knots, and several sets of knitted knitted braided units are arranged in the vertical direction to form a braid row that can be made into a braided unit of a plurality of knitted knots depending on the weight of the strands, A small auxiliary wheel that has one notch for transferring the bobbin to the braided wheels located at both ends of the uppermost and lowermost braided units of this braided row, and has an angular velocity four times that of the braided wheels. and these braided rows are connected by a connecting ring which has four notches for transferring the bobbin and has the same angular velocity as the braided ring to form a braided row in which the braided units of the knots are connected. The object of the present invention is to provide an apparatus for manufacturing a braided knotless net that can be connected in a meandering manner as a whole and can be operated continuously.

<Example> Next, an example of the apparatus for manufacturing a braided knotless net according to the present invention will be described with reference to the drawings.

First, the braided unit A of the net leg is constructed by arranging braided rings in a straight line in the horizontal direction, each having four notches for transferring strands a, b, c, and d, as shown in Fig. 1. . As shown in the same drawing, two pairs of strands a, b, c, and d face each other with one braided ring located in the center as a boundary. The braided rings at both ends are arranged so that the phase between the pairs is 90°. In addition, the following characters appear below.
ha, ni...nu, ru, wo respectively indicate the braiding units of other net legs, and e, f, g...n, o, p
each represents a strand.

Next, regarding the configuration of the braid unit 1 of the kumi knot, the second
As shown in the figure, the braiding units A and B of the net legs, in which the strands a, b...g, h are arranged under the above-mentioned phases, are arranged in two rows above and below, and the braiding units A and B of these net legs are arranged in upper and lower rows. Each of the braided loops is connected with three other braided loops each having four notches for transferring the bobbin, and nine braided loops are connected in a square shape in total. In this case, each strand is a pair of a and b, c and d, e and f, and g and h, but they are diagonally opposite in the square connection of the braid unit 1 of this knot. Pairs of strands (as shown in the figure, a, b and g, h, c, d and e, f) on the braided ring are in phase with each other. As shown in FIG. 3, the device of the present invention may include at least two or more knitted knitted units as described above in the longitudinal direction; The braided loops at each end of each of the braided units of the top and bottom net legs arranged in the vertical direction so as to have one notch for transferring the strand, and four times the number of braided loops. Each small auxiliary wheel C having an angular velocity of is connected to form a braided row (row A). That is, in this figure 3,
Reference numeral 2 denotes a knitted knitted braid unit having the same structure as the knitted knitted braided unit 1, and these knitted knitted units 1 and 2 are connected by another braid ring. Also, with this connection, 3
can also be a braiding unit of a knot.

What is shown in FIG. 4 is another braided row B, which has the same arrangement of the braided rings and small auxiliary wheels as the braided row A, but has a different arrangement of the strands. The differences are as follows. First, the strands of the braid rows constituting the top and bottom net legs in this braid row B row are not arranged. Therefore, in this state, the top and bottom rows constitute the braid unit of the net legs. It means that it is not. . In addition, to the braid unit of the net leg in this braid row B row, the strands e', f'...k',' in E are other braid unit openings, and the strands e, f...k, in C are 90
They are arranged with a phase shift of °. In other words, it is characterized in that the phase between the pairs of two strands on the braided rings at mutually corresponding positions in each braided row is arranged at 90°. For example, the phase of the pair consisting of strands e and f and the pair consisting of strands e' and f' is 90°. As mentioned above, strands are not placed in the top and bottom rows of braid row B, but strands may be placed depending on the weight of the strands, so the number of knots in braid row B is also different. Similar to braid unit 4,
5 and 6 can also be braided units of knotted knots, and can include braided units of a plurality of knotted knots. In addition, these braid rows A and B are to be in contact with each other alternately, and for this purpose, each braid row A and B are connected in a meandering manner using a connecting ring D as shown in Fig. 5. be. This connecting ring D has four notches for transferring the strands, and rotates at the same angular velocity as the braided ring. Also, in Figure 5, the symbol
A ₁ and A ₂ have the same structure as the above-mentioned braid row A, and B ₁ and B ₂ have the same structure as the above-mentioned braid row B, but these are only classified for convenience of explanation to be described later. Therefore, for braiding the net legs and knots, we start from the arrangement of the strands shown in Figure 5, but we take out the braid unit 1 of the knots that constitutes _one row of braid row A in Figure 5. , this is shown in Figures 6 and 7.
To explain based on the figures, Fig. 6 shows the leg braiding process, in which strands a, b, c, and d intersect to form a net leg by braiding unit A of the net leg, and strands e, f, g, h The net legs are intersected and the net legs are braided by the braiding unit openings of the net legs in steps (1) to (13), respectively. If the length of the net leg is long, repeat this operation for that length. FIG. 7 shows the braiding process of knots, in which strands a, b, c, and d and strands e, f, g, and h intersect and are replaced in steps (1) to (9). In other words, this shows that braid units A and B of the net leg are interchanged. The net leg braiding process and knot braiding process are similarly performed for the other braid units 2 and 4 to form the net leg braid unit B,
Figure 8 shows the state in which Ha and Ni, Ho and He, G and Chi, and Li and Nu are swapped.

What is shown in FIG. 9 is a braid row A (A ₁ , A ₂ ,...
...) The strands of the braid units C and I of the net legs on the rows are transferred to the other braid rows B (B ₁ and B ₂ rows) via the connecting ring D, respectively, in steps (1) to (29), and at the same time The strands of the braid units J and F (F are not shown) of the net legs on the braid row A (A ₁ , A ₂ ) are connected to other braids in steps (1) to (29) via the connecting ring D. Column B (B ₁ ,
B ₂ ) Move onto the column. As a result, as shown in Figure 10, the braid unit 3 of the knot is on the braid row A (A ₁ , A ₂ ...) row, and on the braid row B (B ₁ , B ₂ ...) row. In this case, braided units 5 and 6 of the knitted knots are formed, respectively.

To explain this process in detail, steps (1) to (12) are the braiding steps for one cycle of braiding the net legs, during which strand i goes through steps (7) and (12), and strand j goes through ( 9) In the process, strand k
is in step (8), and strand l is rotated once on the small auxiliary wheel in step (6), so that the phase of strand i is 180° in total, strand j,
The net legs are braided while delaying the phases of k and I by 90 degrees. Then, in steps (13) to (29), strand j is transferred to strand k in step (14).
In step (17), strand I is rotated once on the small auxiliary wheel in step (15), and strand J,
The phases of k and I are delayed by 90' and transferred to other braided rows B (B ₁ , B _{2 .} . . ). In this way, in steps (1) to (29), strands i, j, k,
If the strands are transferred to other braid rows via the connecting loops so that the phase of each strand is delayed by a total of 180 degrees, the braided knots before and after the strands are braided with the same structure. Similarly, for strands e, f, g, and h, one cycle of net leg braiding is performed, with strand e being braided in steps (6) and (15), strand g being braided in steps (8) and (17), and strand g being braided in steps (8) and (17). In steps (10) and (14), strand h is rotated once on the small auxiliary wheel in steps (7) and (12) respectively, and the phase is delayed by a total of 180°, and the strand is transferred to another braid row B (B ₁ , B ₂ ...) move up the column. In this way, in steps (1) to (29), strands e, f, g,
If the strands are transferred to another braid row via the connecting ring so that the phases of h are delayed by a total of 180 degrees, the strands will be braided in the same structure at the knots before and after the transfer. Although the braiding process of the net legs in steps (1) to (13) in Figure 9 and the braiding process shown in Figure 6 are different at first glance, the relative positions between the strands are not different, so they are completely the same structure. can be braided. Further, the steps (14) to (29) are the steps of moving the net legs formed by the braiding units C and L and C and C (F are not shown) to the respective adjacent braid rows,
Braid units of other braided legs A, D, H, H, T, N,

f', g', and h' return to their original positions simply by moving on the braided ring without braiding.

Figure 10 shows the leg braiding steps (1) to (13) in Figure 6 and the knot braiding steps (1) to (8) in Figure 7, starting from step (29) in Figure 9. The arrangement state of each strand after proceeding through the same process and braiding the net legs by interchanging the braiding units of A and D, C and H, Ho and Chi, To and Nu, Ri and Wo, Ru and Ka. It is.

What is shown in FIG. 11 is a braid row B (B ₁ , B ₂ . . .
...) Strands e', f', g', h' constituting the net legs on the row are connected to the other braid row A (A ₁ , A ₂ ...)
Strands i′, j′, k′, l′ are transferred onto the rows in steps (1) to (17) and simultaneously constitute the net leg holes and holes on the braid row B (B ₁ , B ₂ ...) rows. The other braided row A
(A ₂ , A ₃ (A ₃ not shown)...) (1) ~ on the column
In the process of transferring in step (17), strand e' is transferred in step (11) and (16), strand f' is transferred in step (9) and (14), and strand g' is transferred in step (10) and In the step (15), the strand h' is rotated one revolution on the small auxiliary wheels in each of the steps (8) and (13), and is transferred via the connecting wheel D with a total phase delay of 180 degrees. In addition, strand i′ is stranded in steps (8) and (13).
j′ is the strand in (10) and (15) steps.
k' is the strand in steps (9) and (14).
In steps (11) and (16), l' is rotated one revolution each on the small auxiliary wheel and transferred via the connecting wheel with a total phase delay of 180 degrees. in this way
By transferring the strands to the adjacent braid row with a 180° phase delay, braiding can be performed without changing the structure of the knots. Then, the strands a, b, c, d, m, n, o, p, i, j, k,
l, e, f, g, and h are returned to their original positions by simply moving the spindle without braiding them.

By sequentially repeating the steps shown in FIGS. 8 to 11, the net shown in FIG. 12 will be completed. The state of the final process shown in FIG. 11 is substantially the same as the original starting state, ie, that of FIG. 5, although the notation of the braided unit of the net leg is different.

Figure 13 shows the braided units A and B of the net legs arranged in two rows horizontally and connected by two other braided rings each having four notches for transferring the bobbin, resulting in a total of eight braided rings.
It is made by connecting several spindles in a square shape, and l' shows another example of the braided unit of the knot. The unit of the net leg and the braided knot by this braid unit is the above-mentioned 6th unit.
The same method as shown in FIG. 7 and FIG. 7 may be used, or a completely different method may be selected.

FIG. 14 is a diagram showing another example in which a braid row in which small auxiliary wheels C are connected is connected in a meandering manner using a connecting ring D, based on the braid unit l' of the braided joints, similar to the previous example shown in FIG. 5. It is. In this case as well, after making the net legs and knotting, the strands are braided in rows A'(A' ₁ , A' ₂ . . . ) by following the same main sequence as in FIGS. 9 and 11 described above.
...) row to another braid row B'(B' ₁ , B' ₂ ...) row, the transition from the braid row B'(B' ₁ , B' ₂ ...) row to another braid row A ′(A′ ₁ , A′ ₂ ……) column,
The organization of the knots before and after the transition is all the same.

<Effects of the Invention> As described above, by using the apparatus for manufacturing a braided knotless net according to the present invention, it is possible to braid all the knots having the same structure as described above, and the reliability of the mesh strength is improved. As well as improving product value,
By arranging the braided rows in a meandering pattern, the number of braided wheels is reduced, and the number of meshing points between the drive gear installed coaxially with the braided wheels is reduced, reducing the chance of failure, and the braided rows can be viewed as one block. This makes maintenance and repair easier, and the braid rows are clearer at a glance, making operation easier, especially when transferring strands from one braid row to another. In order to create a phase difference, a small auxiliary wheel is used instead of a clutch, which allows continuous operation, and has the effect of enabling highly efficient operation since there are no failures caused by clutch operation.
