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 is replaced with 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 cannot be crossed. 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 it is not shown in the figure, in order to intentionally knit the net, the pair of weights of B must be shifted in phase by 90 degrees after crossing the pair of weights of C or either of the pair of weights of B or D. 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 object of the present invention has been made in view of the actual situation in manufacturing such braided knotless nets, and the purpose of the present invention is to solve the above-mentioned drawbacks of mechanisms such as clutches by carefully arranging the weight wheels and arranging the weights therewith. An object of the present invention is to provide a device and a method for easily and efficiently producing a knotless mesh without using a braid.

〔Effect of the invention〕

As described above, one reversing wheel is connected between each of the two rows of driving wheels that are arranged sequentially in the order of forward rotation, reverse rotation, forward rotation, reverse rotation, etc., and the opposite forward rotation wheels. The spindles are arranged in a ladder shape, and the weights are set in pairs with a 180° phase between the weights on each normal rotating wheel, and a 90° phase shift between the weights and the adjacent normal rotating wheels via the reversing wheel. When manufacturing a knotless braided net by arranging the net legs, braiding the net legs, and forming the knots as described above, it is not necessary to provide a clutch for each spindle to adjust the phase of the weights, and it is not necessary to adjust the phase of the spindles. Even if the clutch is arranged in a meandering manner, it is not necessary to provide the clutch all the way depending on the arrangement, but in the embodiments shown in Figs. All you have to do is put in the clutch, and in any case, a complicated, high-maintenance, and expensive device is not required, and a low-cost braided knotless net can be obtained.
