Description

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

[Conventional technology and its issues]

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 is rotated in the forward direction, in the reverse direction, and
They are arranged in a row in a continuous manner with forward rotation, reverse rotation, etc., and 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 that they had a phase of 180°, and a phase shift of 90° between adjacent twisting rings 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 4 constituting the net legs are
Book weights are paired and are 90 degrees out of phase with each other, so it is possible to braid the net legs, but when forming a knot, it is necessary to When a pair of weights exchanges with the two pairs of weights that make up the other mesh leg, there are two pairs of weights with the same phase between each pair of weights, so it is impossible to cross over and the two pairs of weights make up the other mesh leg. This means that you will not be able to do so.

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

However, the provision of a clutch or an auxiliary wheel in this manner has the major disadvantage that the device including its control mechanism becomes complicated and expensive, and also reduces productivity.

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 twisting ring (indicated by a circle with no hatching in the figure) has a pair of two weights, so that they have a phase of 180°, and The 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 lowercase numbers 1 and 2, and a pair of weights 3,
The intersection of the pairs of weights indicated by 4 is shown in the order of uppercase numbers.

FIGS. 3 and 4 are diagrams illustrating that this conventional knotless net manufacturing apparatus cannot knot a braided knotless net having a net leg made of four strands. In Fig. 3, the net leg E is made up of two pairs of weights located on the luck wheels A and B, and the net legs A and C of the net leg F are made up of two pairs of weights located on the luck wheels C and D. Since the various pairs of 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 order to compose a net, the pair of weights of B must have the phase of either the pair of weights of B or D after crossing with the pair of weights of C.
Unless they are shifted by 90 degrees, the pair of weights B and the pair of weights D cannot intersect, and the same is true when the pair of weights A and C are crossed. In order to shift the phase of some pairs of weights and make them cross in this way, the present inventor developed a method for
The problem was solved by inventing No. 149954 and attaching a clutch to the spindle as specified therein. However, adding a clutch not only complicates the mechanism of the manufacturing equipment and makes it expensive, but also becomes a major factor that hinders productivity.

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 drawbacks mentioned above, by carefully arranging the weight ring and arranging the weights in relation to it. An object of the present invention is to provide a device and a method for simply and efficiently manufacturing a braided knotless net without having to do so.

In both figures, the large circles indicate the spindle wheels, the small circles indicate the weights, the ones without diagonal lines indicate the forward rotation wheels, and the ones with diagonal lines indicate the reverse rotation wheels. It shows.

Figure 5 shows the spindle rotating forward, reverse, forward, reverse...
Three consecutive rows of spindle wheels are arranged in parallel and adjacent to each other, and the adjacent spindle wheels rotate in opposite directions. A pair of two weights are attached to each of the three driving wheels, each of which has normal rotation wheels at both ends, with forward rotation, reverse rotation, and forward rotation in the direction perpendicular to For example, weights 1, 2, 3, and 4 are arranged so that the two normal rotation wheels are out of phase by 90 degrees, and these three weight wheels and four weights are combined in this way. This is the basic unit of the first net leg braid. An example of this is the basic unit A. A pair of two weights are attached to each of the three spindle wheels (reverse rotation, forward rotation, reverse rotation, and reversal wheels at both ends) that are adjacent to each other in parallel with this first basic unit (for example, A).
so that the phase is 180°, and the phase is shifted by 90° with respect to the pair of weights arranged on the forward rotating wheel of the first basic unit (for example, A) adjacent to this reversing wheel,
For example, the weights are arranged like 5, 6, 7, 8,
These three spindle wheels and four weights are combined in this way to form the second basic unit. An example is the basic unit RO.

FIG. 6 shows how two net legs of the braid are braided while intersecting the weights placed in each of the two sets of basic units.

That is, the braid is made by crossing the four weights 1, 2, 3, and 4 placed on the first strand between 1 in Figure 6, 12 in Figure 6, and 1' in Figure 6. It shows how the net legs are braided, and the same goes for the four weights 5, 6, 7, and 8 arranged in the second basic unit B. Here, the normal rotation wheel rotates counterclockwise and the reverse rotation wheel rotates clockwise, and each weight wheel rotates 90 degrees from 1 in Figure 6 to 2 in Figure 6.
The same applies below.

As each spindle rotates 90 degrees in this way,
If the stage in which the weight moves is one process, one cycle is completed in 12 processes in this example, but depending on the size of the mesh, this can be repeated several times, and/or the assembly process can be started in the middle. You may move on to the process.

(That is, the same state as 10 in Figure 6 in the net leg braiding process) is transferred to the basic unit RO in 5 steps, and during this time, the weights 5, 6, 7, 8 placed in the basic unit RO are
It can be seen that they shift to the basic unit A and replace each other to form a set knot.

The same is true for Fig. 8, and when the weights 1, 2, 3, and 4 arranged in the basic unit B are in the state 1 in Fig. 8 (that is, the same as the state 5 in Fig. 6), That is,
In the 5 steps up to (same as state 4 in Figure 6), the transition is made to the basic unit C, and during this period, the weights 5, 6, 7, and 8 placed in the basic unit C are transferred to the basic unit B, and the weights are replaced with each other. It can be seen that they form knots.

FIG. 7 and FIG. 8 show two embodiments in which the knotting is started from different steps of the net leg braiding.

By sequentially braiding the net legs and forming knots as described above, a knotless braided net can be manufactured.

〔Effect of the invention〕

As described above, the present invention combines the basic unit of the first net leg braid configured as described above and the basic unit of the second net leg braid adjacent to and parallel to the first basic unit. Therefore, the net legs made of braided cord can be braided while intersecting the four weights arranged in each basic unit. Further, it is possible to form a joint by intersecting the four weights arranged in each basic unit between adjacent basic units, thereby simplifying the apparatus and the manufacturing method.
