Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, the commonly used frogmata knot mesh is organized in a diamond pattern.

For fishing nets such as fixed nets, sports nets, agriculture and seaweed cultivation silk, it is advantageous and convenient to use the silk in a square direction that does not expand or contract in the front, back, left or right directions. The silk used in the square pattern is generally made by cutting diagonally from a rhombus patterned mesh.

Furthermore, square mesh nets are currently produced by hand, without the use of machines, using an inefficient method. The present invention relates to a method for knitting square mesh silk fabric produced by a knitting machine and a knitting machine.

In particular, the purpose is to improve production by linking and automating the rotation of the boat-shaped moving device and the rotational movement of top fishing, and to obtain an improved square mesh net with stronger and more stable knots. That is, the conventional insect cliff or knot is a knot formed by pulling the weft yarn into the warp loop and bending it.

When used in square stitch, the weft loop is opened 90 degrees in a V-shape, and the warp and weft yarns are alternately positioned, making it easy to turn under tension. Therefore, its utility value is low. Diamond mesh silk, in which the warp and weft threads are folded back at knots and runs in a zigzag pattern, is folded back at the knots by V-shaped loops, but the square mesh silk of this invention has a shape in which the warp threads and weft threads pass straight through the knots. There is no turning back. In this invention, the straight warp yarn and the diagonal weft yarn intersect, and at the crossing point, the weft yarn is folded back twice to form an S-shaped loop and knotted with the warp yarn, and the mesh is parallel to each other making an acute angle in the front and back. A bran mesh is made into a quadrilateral shape,
The purpose of this method is to completely silk a square mesh, which is characterized by the warp and weft threads laid out as they are, forming square mesh patterns that intersect at right angles.

In addition, in this invention, the boat shape is moved up and down in a constant lateral direction by an interval of the warp threads for each mesh stage, and during this time, the weft threads are first raised by the upward movement of the boat shape, and the upper hook is moved in the forward direction. Rotate it and hook it to the fishing part of the upper hook, hang the warp thread from the opposite direction of the weft thread to the hook part of the upper hook, rotate it in the opposite direction to the above-mentioned forward direction, remove the weft thread from the upper hook, and lower it. By doing this, the warp loops that are caught on the upper gold thread are warped, and the tip of the fishing part of the upper copper is directed toward the thread swinging side, and then the warp threads are pulled out from the warp thread loops with the lower fishing line, and the weft threads, that is, the boat threads are drawn. A square mesh stripe characterized in that the pattern is passed through the drawn warp loop, the weft is bent by the tension of the warp to form an S-shaped loop, and then the warp loop is removed from the top and fastened. It's in silk fashion.

In addition, the present invention provides a boat-shaped moving device that can move vertically and horizontally and return to its original position so as to sequentially move the boat-shaped boat that has been sent to the boat-shaped receiver by the distance of the warp threads. A knitting machine for square mesh silk is characterized in that it performs a rope netting method.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a warp thread, which is wound around a large number of bobbins at the rear and is inserted in parallel to a thread swinger 3 that moves up and down as well as left and right.

2 is a weft, which is wound around a coin and placed in a boat-shaped box 6.
The fact that it is placed on a fixed boat-shaped receiver 5 attached to the net is the same as that of the one-light knitting machine.

A movable boat-shaped receiver 7 is arranged alongside the fixed boat-shaped receiver 5, and the movable boat-shaped receiver 7 can move vertically and horizontally.
Depending on the weight of the boat 8, it is operated by a small motor or hydraulic pressure. Figure 1 shows a square mesh fabric that is knitted, with 2 wefts being 1
The rope is shown moving horizontally to the left in each row, indicating that the mesh is a parallelogram with acute angles from front to back.

Figure 2 shows the nodule, with figure A' showing the front side and figure B' the back side.

FIG. 3 shows a configuration in which the weft yarns 2 are folded back twice to form an S-shaped loop and knotted with the warp yarns 1 in a state in which the knots shown in FIG. 2A' are loosened. Figure 4 shows the square mesh net developed from the silk fabric shown in Figure 1, and Figure 5 shows its back side.

Figure 6 shows the main parts of this knitting machine in the order of steps (A to H).
From above, they are a rotation direction view of the upper hook 4, a side view of the knotting operation, and a front view of the boat-shaped receiver 5 and the movable boat-shaped receiver 7.

The boat-shaped moving device 10 that holds the movable boat-shaped receiver 7 raises the movable boat-shaped receiver 7 and lifts all the boat-shaped receivers 8 from the concave latching portions 20 of the boat-shaped receiver 5 fixed to the boat-shaped box 6. It is sufficient to move the boat shape 8 to the left by an interval of 1 and lower it, to hook the boat shape 8 to the concave hooking portion 20 adjacent to the left, and then move it to the right and return it to its original position. The number of concave hooks 20 at the left end of the fixed boat-shaped receiver 5 is one more than the number of concave hooks 21 (described later) of the movable boat-shaped receiver 7, and the weft thread 2 of the boat-shaped 8 hooked thereon is cut after knotting. The threads 2 are removed, and the place where the boat shape 8 that advances in the next stage will be placed is raised, the boat shape 8 is inserted at the right end, the weft thread 2 is tied to the silk fabric, and the next stage of mesh formation begins.

'1 As an example, a concave latching part 21 corresponding to the spacing of the warp threads 1 having the same shape as the concave latching part 20 is formed at the top end of the movable boat-shaped receiver 7, and a supporting chest provided at the center of the movable boat-shaped receiver 7. If the lower end of the eccentric cam 11 is provided with a loose iron in the cam groove 13 of the eccentric cam 12, the movable boat-shaped receiver can be moved by the circular operation shown in the diagram A''→B'→C''→B''→A'' in FIG. 7 can perform the above operations.

FIG. 8 is a cross-sectional view of the boat-shaped moving device 10 and the boat-shaped box 6, and numeral 9 indicates an elongated hole bored in the boat-shaped box to allow the support leg 11 to move in the lateral direction. In addition, if the boat type 8 is heavy, the supporting neighbor 11
, the number of cams 12 is lengthened, and the number of cam grooves 13 is increased.

The same effect can also be obtained by using a boat-shaped moving layer that moves laterally by placing the front and rear of the boat-shaped boat on a spiral screw shaft at the same angle as the concave hook 21, and by lifting the weft separately. There is.

Now, referring to FIG. 6, a green silk process according to one embodiment of the present invention will be described.

A process (Figure 6A) The upper fishing rod 4 is facing the line swinger 3 side.

The boat 8 is placed on the fixed boat holder 5, the top surface of the movable boat 7 is lower than the boat 8, and the position on which the boat 8 is placed is slightly to the right of the boat 8. Step B (Fig. 6B) The upper fishing rod 4 rotates about 3/4 to the left and waits for the boat type 8 to rise.

The movable boat-shaped bridge 7 starts moving to the left while rising. Step C (Fig. 6C) The movable boat-shaped receiver 7 rises to the highest level, places the boat-shaped receiver 8 on the fixed boat-shaped receiver 5 on the movable boat-shaped receiver 7, and continues to move to the left.

The upper gold thread 4 turns half a turn to the right and hooks the weft thread 2 that has risen due to the rise of the boat shape 8. ○Process (Fig. 6D) The upper hook 4 further rotates 1/4 to the right so that it faces the thread swinger 3. In conjunction with the thread swinger 3, the warp thread 1 is moved from the left to the right, that is, from the opposite direction of the weft thread 2 to the upper hook 4. Hanging on.

Step E (FIG. 6E) When the upper hook 4 is rotated half a turn to the left, the weft thread 2 comes off the upper hook 4, detours around the outside of the loop of the warp thread 1 hung on the upper hook, and is carried into the box. The movable boat-shaped receiver 7 moves the boat-shaped receiver 8 to the left by one interval of the boat-shaped receiver 5 and starts to descend. F process (Fig. 6 F) Upper fishing 4 turns right 1/public direction and faces the thread swing 3 side and lowers 9
Wait for the entrance.

The movable boat 7 descends, transfers the boat 8 by one interval to the adjacent fixed boat holder 5 on the left, and further descends. Step G (Fig. 6G) The lower hook 9 enters along the groove provided at the bottom of the upper hook 4, and hooks the warp yarn 1 from the left to the right by the movement of the yarn swinger 3.

After the mobile boat type 7 descends to a slightly lower position than the boat type 8,
Start moving to the right. Day process (Fig. 6H) The lower hook 9 pulls the warp thread 1 forward and passes through the boat shape 8 on the fixed boat shape receiver 5 which has finished moving to the left.

The movable boat-shaped receiver 7 moves to the right and stops at a position slightly to the right from directly below the boat-shaped bridge 8. That is, it returns to the position of step A. The relationship between the warp yarns 1 and the weft yarns 2 in this state is as shown in FIG. 61. Step 1 (Fig. 6 1) The warp yarn 1 is pulled to the opposite side by a falling shuttle (not shown), the weft yarn 2 is bent over the loop of the warp yarn 1, and together with the curve that previously bypassed the warp yarn 1 loop, the S The warp threads are entwined in a letter ^ shape, and one loop of the warp thread is removed from the upper hook 4 to form a symmetrical knot structure with one loop of the warp threads in an N shape.

That is, as shown in FIG. 3, the weft threads 2 entering from the lower left extend upward to the right, and the warp threads 1 entering from the lower right extend upward through the knots to the left.

Also, when tension is applied to the warp yarns 1 and the continuation is carried out, the warp threads between each yarn are spread out in all directions, as shown in Figure A' (front side) and Figure B' (back side) in Figure 2. 1 or the loop of weft thread 2 straddles it. Process J The net feed roller rotates and feeds out the silk fabric by the length between the nodules of the mesh.

Thus, the weft thread 2 discharged to the leftmost end of the knot row is cut and removed from the row, and one new weft thread 2 is added to the right end. Tied to net fabric. In this way, the knitting of the first mesh is completed. The present invention is capable of automatically knitting a square mesh with strong knots using a simple device.
