Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a knotted square mesh such as a hexagonal mesh or a square mesh, and a method for manufacturing the same.

<Conventional technology> Conventionally, a diamond mesh mesh is used as a knotted mesh. As shown in Figure 9, this diamond mesh network has a normal mesh expansion of (A) → (B) → (C) → (D), and when tension is applied in the X direction, the mesh becomes (I). ) → (口′) Pass (Ha′) Pass (2′), the angle α becomes smaller than 90°, and when it deforms further, (A) → (口″) → (8″) → (2″ ) to try to approach.

<Problems to be Solved by the Invention> Such diamond mesh nets have been used, for example, as fence nets for fixed nets or enclosing nets, but it is now possible to use them as fence nets for fixed nets or enclosing nets in fishing areas with large tidal currents. If used as a net, the net will be blown away, resulting in poor net formation, and the net near the seabed, which is stretched from the sea surface to the seabed, will be blown up, impairing the intimidation and enveloping effect on fish schools. .

This is because the mesh becomes elongated in the tidal direction, that is, in the horizontal direction, and conversely, the height of the mesh becomes lower in the water depth direction. In addition, tension is applied to the rhombus mesh used in the sleeve net portion of the seine net, and the tightening (= internal fastening) in the seine direction becomes smaller, which means that the mesh size in the height direction becomes smaller and the sleeve net height becomes smaller. The overall temperature decreases.

By the way, on the other hand, for example, in a hexagonal self-net, the first
As shown in Figure 0, if the normal spread of the mesh is (chi) → (su) → (nu) → (ru) → (wo) → (wa), when tension is applied in the X direction, the mesh will become (chi). ′)→(su′)→(nu′)
→ (ru') → (wo') → (wa') The mesh becomes a square mesh, and the angle β becomes 90 degrees, so one of the factors that cause blindness disappears. Therefore, the hexagonal self-mesh is less likely to cause extreme blinding. Square mesh mesh is the most effective way to eliminate the defect of blind mesh, but traditionally, square mesh mesh has been produced by cutting a sheet-like diamond mesh mesh halfway, changing the direction, and piecing it together. However, this has the disadvantage of requiring time and effort.

However, when the above-mentioned square mesh net was simply used as a fence net for a fixed net or as an enclosing net, lacing was conventionally used as a method of connecting to this net sling. However, this work was extremely troublesome and caused a decline in work efficiency.

Means for Solving the Problems> Therefore, the present invention provides a knotted network in which the number of knots constituting the knotted mesh is at least six knots, and four of the six sides are each made up of warp or weft alone. , the remaining two sides are each made up of a warp and a weft, and the hanging rope can be inserted through the sides made up of the warp and weft, thereby making it easy to connect them. This invention was developed for the purpose of providing a nodular mesh mesh and a method for manufacturing the same.

Embodiments Next, embodiments of the knotted square mesh according to the present invention will be described based on FIGS. 1 to 4.

(First embodiment: hexagonal self-net) Figure 1 shows six cylinder nodes A99, H2, E, H, and hexagonal side a,
It is a front view of a hexagonal self-net made up of b, c, d, e, and f, of which two sides c and d are made up of a warp I and a weft 2 as a pair.

(Second example...hexagonal self-net) Figure 2 shows the 8 tubercles A, 22, B, H, H, and H.

It is a front view of a hexagonal self-net consisting of six sides a, b + l + J + g and h, of which two sides 1 + J are a pair of warp 1 and weft 2. It is configured.

(Third example...square mesh) Figure 3 shows the hexagons in Figure 1 stretched to the left and right to form a square mesh, with knots RO and 2 sides a, knots A and 2 sides, and knots C being in a straight line. The 22 sides of the nodule e, the 1 side f to the nodule, and the nodule E are also on a straight line, giving it a quadrilateral shape as a whole.

(Fourth embodiment...square mesh mesh) Figure 4 shows the hexagonal mesh in Figure 2 stretched to the left and right to form a square mesh, with knots 9 and 9 sides a, knots A and 2 sides, and knots C being in a straight line. The two sides of the nodule (g), the nodule (chi) 9, and the nodule (g) are also on a straight line, giving it a square shape as a whole.

Next, we will describe the manufacturing method of each square mesh shown in each of the above examples.First, we will explain the equipment used for this.
This will be explained based on the diagram. That is, in Fig. 5, l
is the warp drawn from the wood pipe (not shown) of the creel stand,
2 is a weft yarn, which is drawn out from a spool 4 housed in the coin coin 3.

Reference numeral 5 denotes a thread swinger, which operates up and down, left and right, and front and back to change the position of the warp threads 1. Numeral 6 is an upper hook which, along with the left and right movement, swings in the thread swing 5 direction and Bunsen 3 direction, respectively, and in conjunction with the action with the thread swing 5, forms a loop of the warp threads 1 on the upper hook 6. Alternatively, this warp loop can be removed. Although this upper hook 6 is not shown, it may be of another type, that is, a known rotary upper hook. 7 is a comb, and is a guide plate for pulling out the formed net downward. 8 is a front hook that performs back and forth movement, left and right movement, and vertical swinging movement. Generally, the front hook 8 often only moves back and forth, up and down, and swings in the vertical direction, but in the present invention, the mounting bar 9 to which the front hook 8 is attached can be moved left and right (not shown). I am trying to make it possible.

Next, a method of manufacturing the hexagonal mesh according to the first embodiment using this apparatus will be explained based on FIG. 6.

That is, starting from FIG. 5, the knot A is created and the eyes are tightened by the steps shown in FIGS. 6 (A) to (I).
From (B), (C), and (D), the warp thread 1 is wound around the upper hook 6 by the horizontal and longitudinal movements of the front hook and the vertical and horizontal movements of the thread swinger 5, and then the thread is wound as shown in (E) and (F). Lower the swing 5 and wind the warp threads 1 around the L-shaped hook 6' of the upper hook 6.
A loop 12 having an intersection 11 between the warp threads is formed.

Thereafter, the front hook 8 moves forward, passes through the warp loop 12, and hooks the warp thread I. And (G).

As shown in (H), the warp thread 1 is pulled out from the warp thread loop 12, the warp thread 1 is removed from the lowered front hook 8, and the weft thread 2 is passed through.

After the warp loops 12 are removed from the upper hook 6 as shown in (I), stitching is performed to form knots and draw out the required net leg length by the required rotation of the stitching reroller 21. After that, perform the stitching as shown in Fig. 6 (J) to
The method of feeding on the 0th day when b is pulled out is that the forward rotation of the stitching is done by attaching a V-groove 22 that is integrally attached to the feeding reroller 21, and a disk 23 that is fitted to the shaft of the feeding reroller 21 and rotates by a chain drive. When the zero disc 23 that carries out stitching by horizontally attaching the wedge 24 rotates in the opposite direction to the stitching, the horizontal attachment is alleviated and the stitching is not performed. The thread swinger 5 then moves to the left by one pitch and uses the corresponding upper hook 6' to move the thread in the direction of the arrow as shown in the figure. Proceed with the steps up to I), tighten the eyes, form the nodule opening, and
Perform the stitching shown in figure (J) to form sides c and d. Then, the thread swinger 5 returns to its original position, and the process proceeds from FIGS. 6(A) to 6(F) to FIG. 6(M), or the steps shown in FIGS. 6(A) to (E)
The process then proceeds to steps (K) to (L), where so-called blank weaving is performed to prevent the formation of knots. This state corresponds to the part X in FIG. 7. After that, the knitting machine performs line-of-sight operations, but since it is empty weaving, it has no effect.

Then, a predetermined stitching may be performed, or no stitching may be performed at all. Naturally, when the stitching is performed, the lengths of sides c and d become longer. Next, the thread swinger 5 moves one pitch to the left and uses the corresponding upper hook 6' to advance the process to Fig. 6 (A) to (I) to form knots 2 and 5 and tighten After performing this step, a stitching step (J) is performed to form sides e and f. Next, the thread swinger 5 returns to its original position and uses the corresponding upper hook 6' to proceed with the steps shown in FIGS. 6(A) to 6(1), and then performs tightening to form a knot. Then perform stitch feed (J). The same operation can be repeated thereafter. The mesh knitted in this way has six knots, and four of the six sides are made up of warp and weft, respectively.
The remaining two sides are made up of pairs of warp threads 1 and weft threads 2.

Next, regarding the manufacturing method of the hexagonal mesh of the second embodiment, knots 2 and E shown in FIG. , to the nodule in Fig. 2, to the nodule in Fig. 1, and then to the nodule in Fig. 1 in the same way as to form the nodule in Fig. 2. . The sides C and e of the mesh knitted in this way are represented by one side i, and the sides d and f are represented by one side i.
Since it can be represented by the side j of the book, it ends up being a hole square, with 8 knots and 4 sides arb + g (h is composed of warp l or weft 2 alone, and the remaining two sides i and j are composed of a pair of warp 1 and weft 2. be done.

The net knitted as described above is used as a fence net for a fixed net, and a state in which it is connected to a hanging rope 24 is shown in FIG.

Note that the square mesh meshes of the third and fourth embodiments can be easily obtained by simply stretching the hexagonal mesh meshes of the first and second embodiments, respectively. .

<Effects of the Invention> As described above, according to the knotted square mesh mesh and the manufacturing method thereof according to the present invention, since the mesh has sides composed of warp and weft, it can be strengthened by itself, and the warp and weft can be strengthened. For example, the above-mentioned hanging rope can be inserted through the sides made of weft threads, thereby making it possible to easily connect them.
