[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus used for attaching juvenile shellfish for bivalve cultivation to a hanging rope, and in order to attach the hanging rope to the hanging rope, a shell thread attaching Taegus thread for shellfish is sequentially provided. The present invention relates to a suspension rope twisting device in a cultivated bivalve juvenile shell mounting device for adding a twist to the suspension rope so that an operation of shifting the position around the suspension rope is easy.

[0002]

2. Description of the Related Art Conventionally, relatively large shellfish such as scallops can be systematically cultured. A method is adopted in which larvae are hung from the raft and fry shells are attached to the rope at required intervals to grow. For this purpose, it is necessary to attach juvenile shells to the rope.As a means for that, select a place in the shell body that does not interfere with growth and make a small hole, and after passing the Tegusu thread through this small hole, Against the required spacing (the spacing that allows a large number to be economically attached without interfering with each other during the growth of the shellfish
Generally, the ends of the above-mentioned Tegus yarns are attached at intervals of about 150 mm by loosening the twist of the strands of the rope and sandwiching them between the strands. All such operations are manual.

[0003]

In order to perform the above-mentioned work for mounting the juvenile shellfish, a great deal of work is required and skill is required. Moreover, if the rope with the juvenile shell attached to it is hung in the sea for a long time, the shell tied to the rope may fall while the rope is twisted due to the flow of seawater and fattening. There is a drawback of.

Therefore, improvement of workability and improvement of so-called yield during fattening period are required. In particular, in the recent manual work that requires a skill even though it is a simple work such as attaching a juvenile to a rope, it is required to facilitate and rationalize the work in recent years. In addition, in the conventional mounting method, the twisting of the rope must be loosened and the juvenile mounting Tegus thread should be sandwiched between the strands of the rope. When combined with the above, it is inevitable that the amount of juveniles attached to one rope will decrease. In other words, productivity will decrease.

In view of such a situation, the present inventors have mechanically tied a small hole provided at a specific position in the shell of a shell through a Tegus thread for shell mounting and suspend the rope. The present invention provides a juvenile-clam attachment device for cultured bivalves that automatically performs the operation of attaching the juvenile clams to the hanging rope in the juvenile-clam mounting device for aquaculture bivalves, and twists the hanging rope. It is an object of the present invention to provide a suspension rope twisting device which can sequentially attach the juvenile shells around the suspension rope at regular positions.

[0006]

In order to achieve the above-mentioned object, the present invention relates to a juvenile shell mounting device for cultured bivalve molluscs, in which a shaft is provided at a position of the suspension rope supply side to a suspension rope mounting operation position for the suspension rope. A rotating plate having a through hole through which the hanging rope can pass is rotatably arranged in the core, and a gear is provided on the rotating plate, and the outside surface of the rotating plate passes through the through hole only in one direction. A plurality of clamp pieces capable of gripping the hanging rope are attached, and the rotary plate is related so as to be driven in the forward and reverse directions by a drive mechanism via the gear, and a juvenile shell mounting operation position with respect to the hanging rope. It is characterized by comprising a clamp mechanism for sandwiching the hanging rope only when the hanging rope is twisted at an appropriate position on the feeding side with sandwiching.

[0007]

In the present invention thus constructed, when the juvenile shell is attached to the hanging rope, the hanging rope is moved every time one piece is attached, and then the clamp mechanism on the advancing side is operated. First, fix the hanging rope, and then rotate the rotating plate forward or backward at the required rotation angle.Hold and hold the hanging rope that penetrates the through hole with the attached clamp pieces and twist it first. By changing the required rotation angle in the circumferential direction with respect to the direction in which the juveniles are attached, the next juvenile attaching operation position can be changed, and juveniles can be attached at a pitch shorter than the conventional juvenile attaching pitch, It is possible to increase the amount of juveniles attached to one hanging rope.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a hanging rope twisting device in a juvenile mounting device for cultured bivalves of the present invention will be described below with reference to the drawings. FIG. 1 is a general schematic view of a juvenile mounting device for cultured bivalves equipped with the hanging rope twisting device of the present invention. FIG. 2 is a diagram showing an outline of the hanging rope twisting device of the present invention. FIG. 3 shows III-III of FIG.
It is a perspective view. FIG. 4 is a view showing a mode of fry shells attached by the device of the present invention.

In these figures, first, the juvenile-fish mounting device for cultured bivalves shown in FIG. 1 has a box-shaped main body frame 1 having an upper surface on which a juvenile is placed in the center portion of the box-shaped main body frame 1 for attachment. Along with the Tegus thread insertion mechanism 2 for penetrating the thread orthogonally to the hanging rope A, a plurality of Tegus thread picking mechanisms 3 and 4 for connecting juveniles to the hanging rope A by the Tegus thread are divided into two upper and lower groups. Are distributed.
The hanging rope A is pulled out from a reel (not shown) by the drive sheave 5 and the driven sheave 5 ′ arranged in front of and behind the main body frame 1 with respect to the jute attachment thread insertion mechanism 2 for tensioning the table. It is designed so that it can be intermittently moved over the required length of time. The Taegus thread insertion mechanism 2 is interlocked with the feeding mechanism of the hanging rope A, and after the feeding of the hanging rope A is stopped, the pipe needle 2c having the Taegus thread inserted therein is penetrated through the hanging rope A from below. After that, only the pipe needle 2c (see FIG. 2) is lowered and retracted so that the Tegusu thread is inserted into the hanging rope A at right angles. Reference numeral 6 is a motor for driving the suspension rope A for feeding.

The Tegusu thread inserted in the hanging rope A is
As it is, it is inserted into a small hole for attachment that has been pre-drilled in a juvenile shell (not shown), and then a knot is attached to the tip end by the Tegus thread picking mechanism 3 on the upper side first, and then the Tegus thread feeding mechanism 2a The juveniles are pulled back by the reverse operation so that the juveniles are held at a position close to the hanging rope A and cut into the required length. Further, this Tegusu thread is then operated by the lower Teguus thread picking mechanism 4 so as to be wound around the hanging rope A and tied.
The hanging rope A used in this device is made of a known synthetic fiber, and the taegus thread is relatively thick. A mode in which the juveniles S are attached to the hanging rope A with the Tegusu thread b is shown in FIG.

Each of the above-mentioned Tegusu thread picking mechanisms 3 and 4 is provided with a picking head (a concrete example is not shown), and the picking head can be opened / closed, moved forward / backward and rotated in a predetermined procedure according to a preset program. It can be raised and lowered. At the same time, a plurality of Tegusu yarn picking mechanisms 3 and 4 are operated to freely operate the Tegusu yarn b to form a loop or insert into the loop.

In the above-mentioned device for attaching a cultured bivalve juvenile, the twisting device 10 for the suspension rope is such that the suspension rope A is intermittently fed along the upper surface of the main body frame 1 and has the above-mentioned gusset in the transfer path of the suspension rope A. It is provided on the supply side with respect to the position where the fry shells are attached by the thread picking mechanisms 3 and 4. And
The hanging rope twisting device 10 includes a rotating plate 11 having a gear 15 provided with a roller clamp mechanism 16 at one end, a drive mechanism 17 for rotating the rotating plate 11, and a mounting operation position for the juvenile shell. The clamp mechanism 20 is provided on the downstream side (feeding side) of a.

The rotating plate 11 is provided with a hanging rope connecting hole 12 at its axial center, and a boss portion 11 'is rotatably supported by the main body frame 1 by a bearing 13. A gear 15 is formed on the outer periphery of the rotary plate 11, and a small gear 19 attached to an output shaft 18a of a drive motor 18 as a drive mechanism 17 arranged in the main body frame 1 rotates the rotary plate 11 through the gear 15. 11 is driven so that it can be rotated in the forward and reverse directions.

The roller clamp mechanism 16 attached to the outer side surface of the rotary plate 11 has a plurality of clamp pieces 16a so that the hanging rope A which moves in only one direction through the through hole 12 of the rotary plate 11 can be grasped. Is movably attached by a pin 16b. Each of the clamp pieces 16a is provided at the tip end in a direction orthogonal to the suspension rope A held by the roller 16c. In addition, the roller 16 at the tip of each clamp piece 16a described above
The c has a function of gripping the hanging rope A from four directions and rotating the hanging rope A, but when the hanging rope A moves in the axial direction, it does not hinder the movement. Therefore, when the rotary plate 11 rotates in the forward or reverse direction, the gripping force by the rollers 16c at the tip of each clamp piece 16a acts in either direction to rotate the hanging rope A in either the forward or reverse direction. It holds a gripping state where it can.

At least one clamp mechanism 20 is provided on the downstream side (feeding side) of the juvenile mounting operation position a.
It is composed of a pair of clamp pieces 21, 21 and a link mechanism (not shown) operated by, for example, an electromagnet for moving them forward and backward,
When the hanging rope A is sent one pitch after the juvenile mounting operation is completed, the clamp piece 21 is excited by the excitation of the electromagnet.
21 holds the hanging rope A for a predetermined time.

In the suspension rope twisting device 10 of the present invention thus constructed, each time the attaching operation of one juvenile shell S (see FIG. 4) to the suspension rope A in the juvenile shell attaching device is completed, First, the clamp mechanism 20 disposed on the downstream side (feeding side) of the fry shell mounting operation position a is operated to fix the hanging rope A, and then the drive mechanism 17 is operated to move the rotary plate 11 straight. When rotated, the clamp mechanism 20
The hanging rope A after the fixed position is rotated by the roller clamp mechanism 16 at a required angle (for example, 180 °). After that, in this state, let the next juvenile mounting operation. After the juvenile shell mounting operation, the fixing by the clamp mechanism 20 is released, and the hanging rope A is directly fed to the feeding mechanism (driving sheave 5).
And the feed drive motor 6 etc.) is operated to move it by a predetermined length.

At this time, as described above, the roller clamp mechanism is used.
Although it is in the gripping state at 16, the suspension rope A is made of synthetic fiber, and the peripheral surface of the roller 16c at the gripping portion has a small frictional resistance in the axial direction with respect to the outer circumference of the rope, so that the suspension rope A moves in the axial direction. The suspension rope A can be moved one pitch without any trouble. After that, the clamp mechanism 20 is operated to fix the hanging rope A, and the rotating plate 11 is reversely rotated by the required angle to repeat the next fry shell mounting operation. Thereafter, such an operation is sequentially repeated.

By being able to operate in this way, FIG.
As shown in, it becomes easy to attach the juveniles S in different directions with respect to one suspension rope A, and when adjacent to each other due to the growth of the shells when suspended in the sea for aquaculture, It becomes possible to narrow the mounting interval of the juveniles S to the range where they do not contact. By the way, the mounting intervals of the juveniles S can be reduced to about half (about 70 mm) by mounting them in a zigzag pattern, which was 150 mm in the past.

[0019]

According to the present invention, since the suspension rope can be rotated with a simple structure and the mounting positions of the juveniles can be regularly distributed around the suspension rope, the installation interval of the conventional juveniles can be widened. Although it was supposed to be taken, the installation interval can be shortened within an allowable range, and as a result, it is possible to increase the amount of juvenile shells to be suspended with respect to one suspension rope and to improve the productivity.
