BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for binding a tailoring thread for attaching a plurality of support ropes to the edge portion of a fishnet such as a gill net, and an apparatus therefor.

[0002]

2. Description of the Related Art Generally, when fish nets are classified according to their uses, they are classified into paper making nets, line nets, gill nets, dragnets and the like. Of these, the gillnet, as shown in FIG.
A support rope 2 having a strip shape or a curtain shape and having a float (referred to as a float or an berber, not shown) provided on the upper edge of the net 1 is attached. Since this type of net is separately manufactured by an automatic knitting machine, in order to attach the support rope 2 to the net 1, after being shipped from the net manufacturing factory, for example, work is performed near the site. .

That is, the attachment of the support rope 2 to the net 1 has conventionally been performed by manually binding the tailoring yarn 3.

Therefore, various proposals have been made in order to improve the work of attaching the support ropes to the net. For example, loop-shaped long ears and short ears made of tailoring yarn are closely and integrally provided on a support rope at a constant span, and the long ears are sewn to the edge of the mesh and passed through this long loop. It has been proposed that the next short ear should be passed through the tip of the ear, then the long ear next should be passed through the short ear, and then the long ear next should sew through the edge of the net. For example, see Japanese Patent Publication No. 2-17136).

However, in such a proposal, although the tailoring thread for attaching the support rope to the net is not tied to facilitate the sewing work, it is still a manual work and has long and short ears. There was a problem of preparing a special support rope.

Further, a method has been proposed in which a support rope having a built-in float is attached to the upper edge of the net by sewing with a sewing machine (Japanese Patent Publication No. 61-29684).

However, the proposed mounting method has a problem that since the sewing machine is overedged, the support ropes are limited to those that can be sewn by the sewing machine. Further, when the tailoring thread is cut off, all of them are frayed. There was a problem.

A method of sewing a pair of support ropes and the upper edge of the net with a coil needle has been proposed (for example, Japanese Patent Publication No. 45-34436 and Japanese Patent Publication No. 53-46).
755, etc.).

[0009] However, the proposed network is not supported by
In the method of attaching the loops, there is a problem that the support loops are limited to those that can be sewn with a coil needle, as in the above-mentioned proposal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention, together with its operation, will be described in detail by the embodiments shown in the accompanying drawings. The present embodiment is suitable for a method of binding a tailoring yarn for attaching a support rope having a built-in float or weight to the upper and lower edges of the gill net, and an apparatus therefor. The present invention is not limited to this, and can be applied to a method of binding other nets and ropes with a tailoring yarn, and an apparatus thereof.

FIGS. 1 to 17 show the binding sequence of the tailoring yarns of this embodiment. In these figures, the support rope 2 is superposed and stretched on the upper edge of the net 1, and the support rope is -The tailoring yarn 3 is gently attached along the pull line 2. A pulling device and a ribbon for tensioning the tailing yarn 3 are attached to the start end and the end of the tailing yarn 3, but these are not shown.

Therefore, in the present embodiment, the supporting rope 2 is attached to the net 1 by the binding machine 6 including the binding rotary piece 4 and the thread take-up rod 5 as described below by binding the tailoring thread 3. .

The binding rotary piece 4 is composed of a disk body, is capable of rotating in the forward and reverse directions, and is supported so as to be able to approach and separate from the support rope 2. A V-shaped groove 7 for guiding the tailoring yarn 3 is formed on the outer periphery thereof, and a radial U-shaped notch 8 reaching the center of the disc is formed. A claw 9 is provided at the opening end of the cutout portion 8 so as to be freely inserted and removed in the disc tangential direction so that the tailoring yarn 3 can be hooked and picked up.

The thread take-up rod 5 is composed of a rod body having a rectangular cross section, and its base is supported so as to be pivotable left and right (supporting rope direction) and forward and backward (orthogonal to left and right), and along the supporting rope 2. And reciprocates in an arc shape, and moves toward and away from the support rope 2.

Therefore, the support ropes 2 provided with the tailoring yarns 3 are superposed on the upper edge of the net 1, and the binding machine 6 is moved to the position where the binding is to be performed. In other words, the binding machine 6 to the net 1
Incorporate the overlapped portion of the upper edge and the support rope 2.

First, as a first procedure, as shown in FIGS. 1, 2 and 3, the binding machine 6 moves in the P direction. The binding rotary piece 4 of the binding machine 6 is supported and rotated. 2
3 and rotate in the direction of arrow a in FIG. 3, the claw 9 of the binding rotary piece 4 catches the tailing thread 3 and picks it up,
The bundling rotating piece 4 supports the supporting rope 2 while winding the tailoring thread 3.
As a result, they move away in the direction of arrow b in FIG. At that time, the thread take-up rod 5 presses the entrance side 3a of the tailoring yarn 3 (the fixed starting end side of the tailoring yarn 3; the same applies hereinafter) of the tailoring yarn 3 accommodated in the binding rotary piece 4 to the support rope 2. Therefore, the tailing yarn 3 is lifted while the entrance side 3a is pressed by the thread reeling rod 5 and the tailing yarn 3 is reeled out from the exit side 3b (the terminal end side from which the tailing yarn 3 is fed). As a result, a first loop A is formed in the middle of the tailoring yarn 3.

Next, as a second procedure, the thread reeling rod 5 is
The space between the support rope 2 and the lifting binding rotary piece 4 is moved in the direction of arrow c in FIG. 4 (see FIGS. 4 and 5).
As a result, the entry side 3a of the tailoring yarn 3 moves under the binding rotary piece 4, comes off the claw 9 and is stored in the V-shaped groove 7, and substantially overlaps with the exit side 3b. A second loop B is laterally formed at the base of the first loop A.

Then, as a third procedure, as shown in FIGS. 7, 8 and 9, the binding rotary piece 4 is brought close to the support rope 2 again, and in particular, the disc which is the base of the cutout portion 8 is made. The center of rotation is brought into contact with the support rope 2. At that time, the entry side 3a of the tailoring yarn 3 is pressed by the base portion of the cutout portion 8,
In addition, in FIG.
It is pressed against the support rope 2 by. Therefore,
The binding rotary piece 4 is in the direction of arrow d in FIG. 9 (the direction opposite to arrow a).
Then, the binding rotary piece 4 is further moved in the direction of arrow e in FIG. 7, but this movement is not necessary if the specified number of rotations is small. As a result, the first loop A formed on the entry side 3a and the exit side 3b of the tailoring yarn 3 becomes two threads, and while the tailoring yarn 3 is fed out from the exiting side 3b, it is The support rope 2 including the approach side 3a of the tailoring yarn 3 is wound at a designated rotation number. That is, the first loop A of the tailoring yarn 3 is wound around the support rope 2. FIG. 10 shows a state in which the tailoring yarn 3 is being wound.

Then, after the tailoring yarn 3 becomes the first loop A in this way and is wound around the upper edge of the net 1 and the support rope 2 in the d direction by the designated number of revolutions, the fourth step is carried out. As shown in Figure 1
As shown in FIG. 1, FIG. 12 and FIG.
When the notch 8 is turned upward, the yarn reeling bar 5 is moved in the space outside the binding rotary piece 4 and positioned directly above the binding rotary piece 4. Therefore, the second loop B is erected from the root of the first loop A. As a result, one of the roots (3a or 3b) of the first loop A around which the tailoring yarn 3 is wound is pulled in such a state that it crosses the notch 8, and the other is bound to the binding rotary piece 4 Is pulled so that it touches the right side of the.

Next, as a fifth procedure, FIG. 14 and FIG.
As shown in FIG. 16 and FIG. 16, the part of the tailoring yarn 3 that crosses the notch 8 is tilted to the left side of the binding rotary piece 4 by a slight turning of the thread reeling rod 5, that is, along the support rope 2. 16 is rotated in the direction of arrow d in FIG. Therefore, the storage portion of the binding rotary piece 4 which is the unwound portion of the first loop A is rotated once through the second loop B. As a result, the cutout portion 8 becomes upward again, and moreover, the person who crosses the cutout portion 8 of the second loop B of the tailoring yarn 3 is placed under the one-turn winding thread by the first loop A. It will be sandwiched. Next, the thread take-up rod 5 is moved to a position where it is disengaged from the tailoring thread 3. (This removing operation does not need to move the thread take-up rod 5 if the binding rotary piece 4 is reversed.)

With the thread take-up rod 5 detached from the tailoring thread 3,
The start and end sides of the tailoring yarn 3 are pulled in the directions of arrows f and g in FIG. 17, that is, the left and right directions to fix the winding yarn of the tailoring yarn 3 (in this case, the trailing end of the winding yarn is fixed and the leading end side is pulled). However, the winding thread is bound and fixed). As a result, the second loop B is lost.

Next, as a sixth procedure, the binding rotary piece 4
Is rotated halfway in the direction of arrow a in FIG. 3 so that the cutout portion 8 faces downward, and the cutout portion 8 is moved away from the support rope 2 to return to the initial state. Therefore, the unwrapped portion of the first loop A exists in the binding portion of the tailoring yarn 3. Next, the binding machine 6 is moved in the P direction to perform the next binding.

Next, an example of the drive device 10 for the binding rotary piece 4 of the binding machine 6 described above will be described. In FIGS. 18 and 19, reference numeral 11 denotes a motor, which drives a pair of upper and lower bevel gears 13 for forward and reverse through a first bevel gear pair 12. The small bevel gear 15 on the outgoing side meshing with the large bevel gear 13 is the second bevel gear pair 16
To drive. The second bevel gear pair 16 is meshed with notch straddle gears 17 and 18, and is meshed with a frame gear 19 that is integral with the binding rotary frame 4. Since the second pair of bevel gears 16, the cutout straddle gears 17, 18 and the binding rotary piece 4 swing around the large bevel gear 13, the binding rotary piece 4 is attached to the support rope 2 as described above. Close to and away from each other.

In this embodiment, the first loop A is formed after the second loop B is formed in advance. However, the present invention is not limited to this, and the first loop A is not limited to this. A is formed first and this first
The second loop B may be formed after winding the loop A including the starting end side of the support rope.

According to the binding method of the present invention, the
Since the tailing yarn of the book can bind the net and the rope at a plurality of spots one after another, the tailing yarn can be bound without cutting the tailing yarn or using the plurality of tailing yarns, and the binding operation is extremely quick. Moreover, since it is a binding by the tailoring thread, unlike rope stitching, any rope (for example, wire rope or bar) can be attached to the net. Moreover,
Even if the starting end or the end side of the tailoring yarn is cut after bundling, since the starting end side of the tailoring yarn is sandwiched by the first loop and the first looper and the end side are tied together, the binding There is no fraying.

Further, according to the binding device of the present invention, since it is composed of the disk and the rod that pass through the mesh of the net, it is extremely simple and compact, and the binding work can be performed at any place.
