Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Applications] The present invention relates to an apparatus and method for producing a braided knotless net having a braided net leg made of four strands.

[Conventional technology]

In conventional knotless nets, two strands are twisted together to form a net leg, and the strands forming one net leg and the strands forming another net leg are crossed to form knots. For this reason, in conventional knotless net manufacturing equipment, the spindle wheel is rotated forward and backward.

Normal rotation, reverse rotation, etc. are arranged continuously in one row, and these are used as twisting rings that alternately twist the net legs and forming rings that form knots, and two wires are attached to each twisting ring. 180 pairs of weights
The twisted wheels were arranged so that the phase was 0, and the phases were shifted by 90° between the twisted rings adjacent to each other via the assembled ring.

However, in the braided knotless net according to the present invention, four strands are braided to form a net leg, and this strand and other strands forming the net leg are crossed with each other to form a knot. Therefore, even if an attempt is made to manufacture this braided knotless net using the above-mentioned conventional knotless net manufacturing apparatus, the four weights that make up the net legs are paired and are 90 degrees out of phase with each other. Since they are staggered, it is possible to braid the net legs, but when forming the braided knots, the two pairs of weights that make up the braided legs are the two pairs that make up the other braided leg.
When the weights are exchanged with a pair of weights, since there are two pairs of weights with the same phase between each pair of weights, they cannot cross over and cannot form a joint.

In order to solve this problem, it is possible to use a clutch to control the rotation of the spindle wheel, as disclosed in Japanese Patent Application Laid-Open No. 51-149954, which was invented by the same person as the present invention, or to temporarily control the rotation of the spindle wheel using an auxiliary wheel. It was also possible to shift the phase of some of the weights in order to allow the weights to be exchanged to perform the knitting.

However, providing a clutch or auxiliary wheel in this way has the major disadvantage of not only making the equipment, including its control mechanism, complicated and expensive, but also reducing productivity. Ta.

To explain the above according to the drawings, Fig. 1 shows the arrangement of the spindle wheel and the weight (indicated by small circles in the figure) in a conventional knotless net manufacturing device having net legs made of two strands twisted together. ), each twisted ring (indicated by a circle without diagonal lines) has a pair of two weights, and a phase of 1800 is obtained. Pairs of weights of adjacent twisted rings are arranged with a phase shift of 90° between them (indicated by hatched circles in the figure).

FIG. 2 is a diagram illustrating how the penetrating knotless mesh is knotted in this conventional knotless mesh manufacturing apparatus, and shows a pair of weights indicated by a lowercase number 1.2 and a pair of weights indicated by 3.4. The diagram shows how the pairs of weights intersect in the order of uppercase numbers.

Figures 3 and 4 are diagrams illustrating that this conventional knotless net manufacturing apparatus cannot knot a braided knotless net having four strands of coarse net legs. , 3rd
In the figure, a net leg E is made up of two pairs of weights located on the luck wheels A and B, and A, C, and B of the net leg F is made up of two pairs of weights located on the luck wheels C and D. Since the various pairs of and D are in the same phase, even if an attempt is made to cross them, the weights will collide, making it impossible to knit the net. For this reason, although not shown in the figure, in order to make a reticulation, the pair of weights of B must shift the phase of either the pair of weights of B or D by 90 degrees after crossing with the pair of weights of C. B
The pair of weights , and the pair of weights D cannot intersect, and the same is true when the pair of weights A and C intersect. In order to shift the phase of some pairs of weights and make them intersect in this way, the present inventor made the invention in Japanese Patent Application Laid-open No. 149954/1983, and as specified therein, by attaching a clutch to the spindle wheel. Settled. However, adding a clutch complicates the mechanism of the manufacturing equipment,
Not only was this expensive, but it was also a major factor hindering productivity.

The figure shows how the net legs of the braid are braided while intersecting the four strands of the braid, and the weight 5.6 is placed at the second basic unit opening.
．． The same applies to the four pieces of 7.8.

Here, the forward rotation wheel rotates counterclockwise, and the reverse rotation wheel rotates clockwise, and each weight wheel rotates 90 degrees from 1 in FIG. 6 to 2 in FIG. 6. The same applies below.

If the stage in which the weights shift as each spindle wheel rotates 90° is considered to be one process, then in this example there are 12 steps.
One cycle is completed in this process, but depending on the size of the mesh, this may be repeated several times, and/or the process may be shifted to the tying process in the middle.

FIGS. 7 and 8 illustrate the braided unit of the knot, and each of the braided units arranged in the basic unit at the same time.

This shows how four weights are intersected to form a knot.

Arranged adjacent to the kumite row, six weight rings are arranged in a rectangular shape to form a braided unit of kumi-bushi.

At 1 in Fig. 7 (that is, the same state as when reaching 11 in Fig. 6 in the net leg braiding process), the weights 1, 2, 3, and 4 arranged in basic unit A are at 6 in Fig. 7. (In other words, the same state as 10 in Fig. 6 in the net leg braiding process), the transition to the basic unit opening takes place in the 5 steps, and during this period, the weights 5, 6, 7, 8 placed at the basic unit opening are It can be seen that they shift to the basic unit A and replace each other to form a kumitsu.

The same applies to FIG. 8, and in 1 of FIG. 8 (that is, the same state as 5 of FIG. 6), the weight 1.
2.3.4 transitions to the basic unit in 5 steps up to 6 in Figure 8 (that is, the same state as 4 in Figure 6), and during this time the weight 5.6° placed in the basic unit C It can be seen that 7.8 moves to the basic unit mouth and replaces each other to form a kumitsu.

FIGS. 7 and 8 show two embodiments in which the braiding is started from different steps in the net leg braiding process.

FIG. 9 is an explanatory diagram showing how the formation of the net am group and the knot knots is performed successively, including the formation of the net mts group in FIG. 6, the formation of the knot knots in FIG. 7, and the formation of the knot knots in FIG. 8. are synthesized and shown continuously.

That is, 1 in FIG. 9 to 11 in FIG. 9 are exactly the same as 1 in FIG. 6 to 11 in FIG.
2.3.4 and the weights 5.6.7.8 of the base unit mouth are shown respectively braiding the net legs.

11 in FIG. 9 to 16 in FIG. 9 are exactly the same as 1 in FIG. 7 to 6 in FIG.
．． 2.3.4 and weight 5.6.7.8 intersect to form a knot. 16 in Figure 9 to 23 in Figure 9 are 10.11.12 and 1 to 5 in Figure 6.
There is a weight in a similar position, and the net legs are braided.

23 in FIG. 9 to 28 in FIG. 9 are exactly the same as 1 in FIG. 8 to 6 in FIG. It shows how .6, 7, and 8 intersect to form a knot. 28 to 37 in FIG. 9 are exactly the same as 4 to 12 and 1' in FIG. 6, and the net legs are braided.

In this way, we have shown examples of the case where the braiding starts from the 5th step and the case where the braiding starts from the 11th step among the net leg braiding processes, but this is done by selecting two combinations according to the size of the mesh. do it.

Figures 10 to 14 are explanatory diagrams of embodiments in which braided knotless nets are formed according to the present invention.
. . . specifies two pairs (four) of weights forming each net leg, and B, e, . . . indicate a set of net legs forming a set joint. First, in FIG. 1O, each net leg is braided in the method shown in FIG.
s1 and 2, net legs 3 and 4 in B, net legs 5 and 6 in C, and so on, when the weights intersect and exchange in the manner shown in Figure 7 or Figure 8 to form a knot. , each pair of weights is arranged as shown in FIG. Either move the weights to the positions of each two pairs of weights shown in Figure 11 after braiding the net legs in this arrangement, or move the weights to the positions shown in Figure 11 immediately after the knots are finished. However, in any case, when transitioning from the weight arrangement shown in Figure 10 to the weight arrangement shown in Figure 11, the end of the arrangement of the spindle wheels should be The weights located in the 2.1.4. ...is from row knee to rowi, IIf
iN7 transitions from row knee to haech and so on.

Next, in FIG. 11, for example, in the knot combination A, net legs 1 and 4 are used, in B, net legs 3 and 6 are used, and in C, net legs #5 and 8 are used.
The weights intersect and exchange in this way to form a set of knots, resulting in the arrangement of each pair of weights as shown in FIG. 12. Furthermore, the weights with braided net legs are moved as shown in Fig. 13, but at this time, the weights with the end of the arrangement of the spindle wheel ζ are moved as shown in Fig. 10 and 1.
In the direction opposite to the transition to Figure 1, and in the opposite direction to the other weights, move two spindles, for example, N
a@15.20.17-=Lt Nu-9kaI"+ 9-
In F, network II #18 transitions from Knoop to Chinu, and so on. Next, in the 11th step, the weights are crossed and exchanged to form a knot, such as, for example, in the combination H of the knot, nets H18 and 13 are used, and in the combination ■ of the cut length, the net legs 15 and 20 are exchanged. (.

In addition, there are some weight wheels that are not used at all in the fabric manufacturing method shown in Figures 10 to 14, such as E, H, G, and W in the top row of the figures, and I in the bottom row.
