Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] 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 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
A pair of twisting rings are arranged in a row in a forward rotation, a reverse rotation, and alternately twist the net legs, and a pair of braided rings are used to form knots. The twisted wheels were arranged so that they had a phase of 180°, and the phases of adjacent twisted rings were shifted by 90° between the assembled rings.

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
Since two book weights are paired and are 90 degrees out of phase with each other, it is possible to braid the net legs, but when forming a knot, it is necessary to When replacing the two pairs of weights that make up the other net leg that connects with the pair of weights, there are two pairs of weights with the same phase between each pair of weights, so they cannot cross over and cannot connect. 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. 149954/1989, 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 and 2.
The intersection of the pairs of weights shown in 4 is shown in the order of uppercase letters.

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 intersect in this way, the present inventor developed a method in Japanese Patent Application Laid-Open No.
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.

5 to 7 show embodiments of the present invention. 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. There is.

FIG. 5 explains the basic unit of the net leg braid, and shows how the net leg of the braid is braided while simultaneously intersecting four weights arranged in the basic unit.

That is, in 1 of FIG. 5, weights 1, 2, 3, 4
The forward rotation wheel that is arranged and the reverse rotation wheel that is sandwiched between them are lined up in a straight line so that the three spindle wheels are forward rotation, reverse rotation, and forward rotation, and both ends are the forward rotation wheels. Two weights 1 and 2 and two weights 3 and 4 are attached to each of these normal rotation wheels.
The book weights are arranged as a pair so that they have a phase of 180 degrees, and the pair of weights 1 and 2 and the pair of weights 3 and 4 are arranged with a phase shift of 90 degrees from each other. The four weights are combined in this way and form the basic unit of the first net leg braid.

In addition, the reversing wheels on which the weights 5, 6, 7, and 8 are arranged and the normal rotating wheels sandwiched between them are such that the three driving wheels are reverse rotation, forward rotation, and reverse rotation, and both ends are reverse rotation wheels. They are arranged in a straight line and adjacent to the first basic unit in parallel with each other, and each reversing wheel has weights 5 and 6.

The braided cord net is created by intersecting the four weights of weights 1, 2, 3, 4 and weights 5, 6, 7, and 8 arranged in the first and second two sets of basic units. It shows how each leg is braided. Here, the forward rotation wheel is counterclockwise, and the reverse rotation wheel is clockwise, as shown in Figure 5.
From there, each weight wheel rotates 90 degrees, and the weight moves to 2 in Figure 5. The same applies below. If the stage in which the weight shifts as each spindle wheel rotates 90 degrees is considered to be one process, one cycle is completed in 12 processes in this example, but depending on the size of the mesh. This can be repeated any number of times, and/or the process of tying can be started in the middle.

Figures 6 and 7 are for explaining the braiding unit of the Kumi Kumitsu, and show how the Kumi Kumitsu is formed by intersecting each of the four weights arranged in the basic unit at the same time. .

That is, in 1 of Fig. 6 (this is the same state as 11 of Fig. 5), the basic unit A in which the weights 1, 2, 3, and 4 are arranged, and the basic unit A in which the weights 5, 6, 7, and 8 are arranged. Two sets of the arranged basic units RO and RO are arranged adjacent to each other in parallel, and six spindle wheels are arranged in a rectangular shape to form a braided unit of the knot.

(In other words, the same state as 10 in Fig. 5 in the net leg braiding process), the transition is made to the basic unit RO in the 5 steps, and during this period, the weights 5, 5, 7, which were placed in the basic unit RO,
It can be seen that 8 moves to the basic unit A and replaces each other to form a kumitsu.

The same is true for FIG. 7, and the weights 1, 2, 3, and 4 arranged in the basic unit in 1 in FIG. 7 (i.e., the same as the state in 5 in FIG. Fifth
In the 5 steps up to (same as state 4 in the figure), the transition is made to the basic unit C, and during this time, the weights 5, 6, 7, and 8 placed in the basic unit C are transferred to the basic unit B, and they are exchanged with each other to form the kumitsu. It can be seen that it is formed.

FIGS. 6 and 7 show two embodiments in which the knotting is started from different steps of the net leg braiding.

As described above, a knotless braided net can be manufactured by sequentially performing the braiding of the net legs and the formation of knots.

〔Effect of the invention〕

As described above, the present invention provides a set having two sets of basic units in which a first net leg braid basic unit and a second net leg braid basic unit configured as described above are arranged adjacent to each other in parallel. Since the knitting units are knots, the braid is braided while intersecting the four weights placed in each basic unit, and also by crossing the four weights placed in each basic unit between the basic units. A combination joint can be formed, and the apparatus and method can be rationally simplified.
