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
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. 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 auxiliary wheel in this manner has the major disadvantage that the device including its control functions becomes complicated and expensive, and productivity is reduced.

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 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 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 purpose of the present invention was made in view of the actual situation in manufacturing such a braided knotless net.The purpose of the present invention is to solve the above-mentioned drawbacks of mechanisms such as clutches by carefully arranging a weight wheel and arranging a weight in relation to the weight wheel. An object of the present invention is to provide a device and method for easily and efficiently producing a knotless braided net without using.

That is, in 1 of FIG. 5, weights 1, 2, 3, 4
The forward rotation wheel and the reverse rotation wheel sandwiched between them are arranged 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. Each normal rotation wheel has two weights 1 and 2 and two weights 3 and 4.
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 net leg braid. This is weights 5, 6, 7,
The same goes for the four 8's and the three related luck wheels.

are weights 1, 2, 3, and 4 arranged in two sets of basic units.
It also shows how each of the net legs of the braid is braided while crossing each of the four weights 5, 6, 7, and 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. 5 to 2 in FIG. 5. The same applies below. If the stage in which the weights shift as each spindle wheel rotates 90 degrees is considered to be one process, one cycle is completed in 12 processes in this example, but this may vary depending on the size of the mesh. It is possible to repeat this several times, and/or to move on to the tying process in the middle.

FIG. 6 shows how four weights arranged in two sets of basic units are intersected to form a knot.

This figure shows how the braided net legs are formed into knots by intersecting each of the four weights between the basic units via a reversing wheel. It can be seen that in this example, the knitting is completed in nine steps and the next step, the first step of net leg braiding, is reached.
