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 auxiliary wheel in this manner has the major disadvantage that the device including its control mechanism becomes complicated and expensive, as well as reducing 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, 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 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.

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.

Figure 5 shows that the spindle wheels are arranged vertically and horizontally in a continuous manner in the form of a checkerboard, with normal rotation, reverse rotation, normal rotation, reverse rotation, etc. Two weights are placed on each of the normal rotation wheels.
They are arranged so that they are 180° in phase with each other as a pair, and 90° out of phase between both normal wheels,
This is the basic unit of the first net leg braid. For example, this is the basic unit shown in A. Also, an inversion parallel to and adjacent to the first basic unit (e.g. A),
A pair of two weights are placed on each of the three spindle wheels, one for forward rotation, one for reverse rotation, and a reversal wheel at both ends, so that the weights are 180° in phase with each other, and The pair of weights arranged on the forward wheels of the first basic unit (for example, A) are arranged so as to be out of phase by 90 degrees, forming the second basic unit. An example of this is the basic unit shown in B.

FIG. 6 shows how two braided cords are braided while intersecting the weights placed in each of the two 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.

FIGS. 7 and 8 explain the knitting unit of the knitting knot, and show how the knitting knitting unit is formed by intersecting each of the four weights arranged in the basic unit at the same time.

1), the weights 1, 2, 3, and 4 placed in basic unit A are 6 in Figure 7.
(In other words, the same state as 10 in Figure 6 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, 6, 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. 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.

FIG. 9 is an explanatory diagram showing how the net leg braid and the braided joints are formed in succession, and the net leg braid in FIG.

That is, 1 in FIG. 9 to 11 in FIG.
It is exactly the same as 11 in Figures 1 to 6, and shows how the weights 1, 2, 3, 4 of basic unit A and the weights 5, 6, 7, 8 of basic unit B braid the net legs, respectively. It shows.

11 in Figure 9 to 16 in Figure 9 are 1 in Figure 7
Or similar to 6 in Figure 7, between the basic units A and B, weights 1, 2, 3, 4 and weights 5, 6, 7, 8.
It shows how they intersect to form a knot. 16 in FIG. 9 to 23 in FIG. 9 have weights at the same positions as 10, 11, 12 and 1 to 5 in FIG. 6, and braid the net legs. Figure 9 2
28 in Figures 3 to 9 are 1 to 8 in Figure 8.
It is similar to 6 in the figure, and the basic units B and C are weights 1, 2, 3, and 4, and weights 5, 6, and 7, which are indicated by small black circles.
It shows how the 8's intersect to form a set knot. 28 to 37 in FIG. 9 are exactly the same as 4 to 12 and 1' in FIG. 6, and the net legs are braided.

In this way, we have shown examples of the case where the braiding starts from the 5th step and the case where the braiding starts from the 11th step of the net leg braiding process, but these can be selected and combined according to the size of the mesh. do it.

FIGS. 10 to 14 are explanatory diagrams of an embodiment of forming a braided knotless net according to the present invention,
1, 2, 3, . . . specify two pairs (four) of weights that form each net leg, and A, B, C, . There is. First of all
In Figure 0, each net leg is braided in the manner shown in Figure 6. For example, in knot combination A, net legs 1 and 2 are braided in the manner shown in Figure 6.
However, in B, net legs 3 and 4, in C, net legs 5 and 6,
If the weights intersect and exchange in the manner shown in Figure 7 or Figure 8, respectively, to form a knot,
The two pairs of weights are arranged as shown in FIG. Either braid the net legs in this arrangement and then move the weights to the positions of each two pairs of weights shown in Figure 11, or move the weights to the positions shown in Figure 11 immediately after the braiding is completed. You may choose to braid the net legs in that arrangement, but in any case, when transitioning from the weight arrangement in Figure 10 to the weight arrangement in Figure 11, it is important to The weights at the ends are two weight wheels in the opposite direction from the weights at the other ends, for example, the net legs 2, 1, 4, etc. are from row knee to row knee, The net leg 7 moves from row knee to row knee and so on. Next, in Fig. 11, the weights are crossed and replaced, for example, in the joint combination A, net legs 1 and 4, in B, net legs 3 and 6, in C, net legs 5 and 8, and so on. A set of knots is formed, and each pair of weights is arranged as shown in FIG. Furthermore, the weights with braided net legs move as shown in Figure 13, but at this time, the weights at the ends of the arrangement of the spindle wheels move as shown in Figures 10 and 1.
In the opposite direction to the transition to Figure 1, and in the opposite direction to the other weights, two spindles, for example, net legs 15, 20, 17, etc. are moved from Nuwo to Wo. -ka, the net leg 18 transitions from nu-wo to chi-nu, and so on. Next, in the 11th step, the weights are crossed and exchanged, for example, the net legs 18 and 13 are used for the combination H of the set knots, and the net legs 15 and 20 are used for the combination of cut lengths, and so on to form the set knots. To go.

In addition, there are some weight wheels that are not used at all in the fabric manufacturing method shown in Figures 10 to 14, such as E, H, T and W, C, YO in the top row of the diagrams, and I, B, and I in the bottom row. C, R, N, R and R may be omitted and provided in advance.

In this way, it is possible to produce a knotless mesh fabric with penetrating braids.
