Description

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

[Conventional technology]

In conventional knotless nets, two s1-lands are twisted together to form a net leg, and the strands forming one net leg are crossed with the strands forming another net leg to form knots. Ta. For this reason, in conventional knotless net manufacturing equipment, the spindle wheel is rotated forward and backward.

Forward rotation, reverse rotation, etc. are arranged continuously in one row, and these are used as a twisting ring that alternately twists the net legs and a grouping ring that forms knots, and each twisting ring has two wires as a pair. The weights were arranged so as to have a phase of 180°, and a phase shift of 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 exchanging 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, the provision of a clutch or an auxiliary wheel as described above, including the splitting mechanism, has the major disadvantage of not only making the device complicated and expensive, but also reducing productivity.

To explain the above according to the drawings, Fig. 1 shows the arrangement of the M weights and the weights (indicated by small circles in the figure) in a conventional knotless net manufacturing device having net legs made of two strands twisted together. This figure shows the arrangement of two weights on each twisting ring (indicated by 9 without hatching in the figure) so that they have a phase of 180° and a pair of weights. ring(
In the figure, the pairs of weights of adjacent twisted rings are arranged with a phase shift of 90° with respect to each other through a circle (indicated by a hatched circle).

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 lowercase numbers 1.2 and 3.4. The figure below shows how the pairs of weights shown in Figure 1 intersect, in the order of uppercase numbers.

Figures 3 and 4 illustrate that with this conventional knotless net manufacturing apparatus, it is impossible to knot a braided knotless net having a net leg made by braiding four strips. In the figure, in Fig. 3, there is a net leg E which is made up of two pairs of weights located at the wheel B, and a net leg F which is made up of two pairs of weights located at the wheel C and D. Since the various pairs of input and C and B and D are in 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 knitting net, the pair of weights of B must be crossed with the pair of weights of C, and then
Furthermore, unless the phase of any pair of weights in D is shifted by 90 degrees, the pair of weights in B and the pair of weights in D cannot intersect, and the same is true when the pair of weights in person and C are crossed. 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, is it necessary to attach a clutch to the 81 side of the manufacturing equipment? Jj
Not only was this complicated and expensive, but it was also a major factor hindering productivity.

[Purpose of the invention]

The present invention was developed in view of the actual situation in the production of braided knotless nets, and it eliminates the use of mechanisms such as clutches, which have the disadvantages mentioned above, by providing a clever weight wheel and arranging the weights in relation to the weight wheel.

That is, 1 to 12 in FIG. 6. Figure 6 1' shows how the weights 1.2.3.4 and 5.8.7.8 move in sequence and intersect to braid the net legs of one braid each. If we consider the movement of the weight each time the spindle rotates 90 degrees as one step, one cycle will be completed in 12 steps, but depending on the size of the mesh, this can be repeated several times. , and/or may proceed to the tying process in the middle.

Here, the basic units are weights 1.2.3.4 and [! 5
．． The example was made as two sets with the arrangement of 6.7.8, but the weight 1
Two sets of arrangements ゜2.5゜6 and i 3.4.7.8 may be used as respective basic units.

Figure 7 shows the arrangement of the basic units shown in Figure 6 and the adjacent basic units via the reversing wheels in a direction perpendicular to the arrangement of the basic units shown in Fig. 6. This figure shows an example in which a set of knots is formed while crossing.

That is, 1 in FIG. 7 (this is the same state as 12 in FIG. 6) to 9 in FIG. In the 9 steps up to 1' in Figure 7, the respective weights 1, 2, 3, 4 and 5, 6, 7, 8 are crossed with each other via the reversing wheel to form a joint. It can be seen that in this example, the braiding is completed in 9 steps and the next step is the first step of braiding the net legs.

First, looking at Fig. 8, for example, net leg 1 is braided in the basic unit A, and net leg 2 is braided in the mouth basic unit, and then the weights of net leg 1 and net leg 2 are combined into a knit knot. This shows that A will be formed. Next, looking at Figure 9, it shows a state in which the assembly of the combinations in Figure 8 has been completed and the weights of each net leg have been replaced.For example, in the basic unit of the mouth, net leg 1 is now unevenly assembled. , which shows that the weights of net leg 1 and net leg 4 will then form a set B. In this way, two braided knots of the net legs are formed...
The net fabric is knitted by repeating...

FIG. 10 shows the state in which the net fabric is knitted in this manner. The numbers here are different from those in Figures 8 and 9, and are 1, 2.3.

・ ・ are knotted, and a penetrating braided knotless net is knitted in the same manner.

When the spindles are continuously arranged in the Z kotari and braided knotless net manufacturing apparatus according to the present invention, the rows of ladder-like spindles are arranged in a straight line or in a circular shape. Alternatively, they may be arranged in an arc shape, or it is also possible to increase the number of turns in a spiral shape as shown in FIG. 11 to reduce the size of the entire manufacturing apparatus. Furthermore, FIG. 12 shows an embodiment in which the row of spindle wheels is arranged in a meandering manner. FIGS. 13 and 14 show how the braided knotless net is knitted in this case. The symbols shown here are 1.2.3. ・ indicates two pairs of weights (four) that make up the net legs, A, B
, C... are M! forming each set of knots. It shows the legs together.

First, in FIG. 13, after the net legs have been braided using the method shown in FIG.
In B, the net legs 3 and 4 and in C, the net legs 5 and 6 intersect and replace each other to form a knot, resulting in the arrangement of the two pairs of weights shown in FIG. 14. At this time, for example, the method disclosed in Japanese Patent Application Laid-Open No. 51-149954, which was invented by the same person as the present invention, can be used for the 6 sets and H sets of folded knots of the ladder-like row of spindle wheels. reactor. Next, in FIG. 14, for the combination A of the knots, net legs 1 and 4 are used, for B, net legs 3 and 6 are used, and for C, net legs 5 and 8 are used.
They intersect and replace each other to form a set of knots.

Figures 15, 16, and 12 show another example in which the rows of spindles are arranged in a meandering manner, and the examples shown in Figures 13 and 14 show the portions where the rows of spindles turn around. In this embodiment, a clutch must be inserted into a part of the spindle wheel, but this embodiment does not require a clutch at all. The meanings of the symbols shown here are the same as in FIG. 13. First, in Fig. 15, for example, in the joint combination A, net legs 1 and 2 are connected, in B, net legs 3 and 4, in C, net legs 5 and 6, and similarly in E, net legs 9 and 1 are connected.
0 intersect and are exchanged to form a set of knots, resulting in the arrangement of two pairs of weights shown in FIG. The pair of weights at the turn-back portion of the spindle wheel is moved so that they become the pair of weights shown in FIG. 16 to FIG. 17.

In this case, the braiding of the net legs can be done before or even after the weight transfer. Next, in FIG. 17, net legs 1 and 4 in combination A, 3 and 6 in combination B, and 5 and 8 in combination C intersect and replace each other to form a combination.

In this way, a penetrating braided knotless net fabric can be manufactured.
