[0002]

2. Description of the Related Art In the tuna longline fishery, when a trunk line is thrown into the sea from a hull lancing machine, a fishing line at the tip of a large number of branch lines attached to the trunk line at appropriate intervals is maintained. They feed the bait and throw it at a predetermined location. This bait is usually performed about 3000 times in one rowing operation, and its quality is an important operation that greatly affects the catch.

[0003] Usually, the main ropes unwound by a line hauler are stored in a main rope storage box at the stern, and the rowing operation is performed from an early morning. In this littering work, the littering work is basically performed manually, and as shown in FIG.
The snap 3 of the branch line 2 tied to the main line is placed on the main line feeding machine 4 side, the fishing hook 5 is fixed on the non-feeding machine side, the bait 6 is loaded on the fishing hook 5, and the riding of B is performed. personnel move Tonawa conveyor 1 comprising a pitch conveyor by operating the foot switch to one pitch at a time aft D.

[0004] The crew member C waiting for binding holds the snap 3 of the branch line 2 reaching the end on the lasso conveyor 1 in the right hand, and is pulled out from a trunk line storage box (not shown) by a feeder 4. The main rope 7 is grasped with the left hand, and the snap 3 is tied to the main rope 7 based on the branch rope connection instruction sound of the throwing indicator, and the stern end rope 2
Is held by the left hand so as to form a straight line without resistance. Then, the crew of B waiting for feeding is about 2 km from the feeding position.
The 50 mm place is held by the right hand and the rope is ported at about 30 degrees in the port direction in consideration of the eddy current caused by the screw of the hull. Usually, about 3000 branch ropes 2 are fed manually once.

[0005]

Since such a conventional feeding operation is based on a manual operation, it cannot be fed far away from the hull. The problem is that food loss is often high. Especially when feeding within 6m of the hull, the loss of food is high due to the long time of staying on the sea surface due to the effect of the screw of the ship, and more than 20% of the 3,000 feedings at a time Feeding within this 6m.
Furthermore, seabirds hooked on hooks often die, which is not preferable from the viewpoint of protection of the natural environment. In particular, tuna longline fishery is a pelagic fishery and cannot be carried out without the understanding of neighboring countries.

[0006] Further, in the conventional feeding operation, there is a limit to the improvement of the work efficiency, and it is difficult to continue feeding at an accurate place. There is a problem that the mental and mental burden is large. In addition, the trunk ropes 7 are often entangled with each other at the time of throwing, or the branch ropes 2 and the trunk rope 7 are often entangled with each other. Intense pitching and rolling makes the above-mentioned feeding operation particularly difficult.

In order to cope with the above, the applicant of the present application has previously disclosed in Japanese Patent Application No. 6-105971, which is located on the stern side of a fishing boat as shown in FIG. A motor 11 that is provided and that can adjust the rotation angle, rotation direction, and rotation speed of the output shaft; a feeding arm 21 that is rotatably mounted on the output shaft of the motor 11 via a support rod in a substantially horizontal plane; We proposed a feeder equipped with. The above motor 1
The lower cover provided on one of the lower portion, the input terminal 11a of the drive control signal to the motor 11, 11b is deployed. The feeding arm uses a gutter-shaped member having a U-shaped cross section.

[0008] According to such a feeder, the crew places the bait on the fishing hook of the branch line tied to the trunk line on the bait arm 21 and outputs a beeping indicator sound (not shown). By tying the snap to the trunk line based on the above and activating the feeder, the motor 11
The feeding arm 21 is rotated in a substantially horizontal plane due to the rotational force of the motor, and the motor 11 is suddenly stopped, so that the feeding arm 21 is suddenly stopped at the position indicated by the imaginary line in FIG. Thereafter, the feeding arm 21 is reversely rotated in a substantially horizontal plane by the reverse rotation of the motor 11 to return to the original placement position, and the feeding operation can be continued.

Further, an oscillating flange shaft projecting from a mounting base 12 fixed to a motor 11 via a support plate is rotatably inserted into an annular hole of a mounting bearing fixed to the hull side. Since the motor 11 is swingably disposed inside or outside the hull, when the hull rolls, a pair of rocking stop shafts extending outward from both sides of the rocking flange shaft are applied to the hull side. The elevation angle of the feeding arm 21 with respect to the sea surface is kept substantially constant by contact, and it is possible to prevent an excessive tilting of the baiting machine.

However, even in the case of this baiting machine, since the crew member activates the baiting machine with the manual switch based on the branch rope tie sound of the baiting indicator, it is difficult to operate the baiting interval. However, there remains a problem that the accuracy of the vehicle is limited and skill is required for the crew.

Accordingly, the present invention relates to the above-mentioned Japanese Patent Application No. Hei 6-10597.
Foraging in the longline fishery, which improves the baiting machine proposed by No. 1 and automatically starts the baiting machine based on the signal of the baiting indicator without relying on the manual operation of the crew. The purpose is to provide a machine .

1 is kept substantially constant with respect to the sea surface,
Is prevented from being excessively tilted.

The placement position of the feeding arm 21 when the bait 6 is placed is the position of the feeding arm 21 at the start of feeding, and the direction of rotation of the feeding arm 21 is such that the feeding machine 20 is mounted on the ship. It is clockwise when mounted and counterclockwise when mounted outboard. Therefore, when the wind direction is from the port side in a rough sea, the feeding direction may be changed to the starboard side. Furthermore, the placement position of the bait 6, that is, the feeding start position, can be appropriately changed depending on the state of the sea or the wind in order to throw the branch rope 2 at the reference throwing angle. Further, Toesa position and distance of the food 6 is adjustable by the rotation angle and the rotation speed of the output shaft 18 of the AC servo motor <br/> over motor 11.

By feeding the bait 6 from the placement position by accelerating 1/3 rotation and returning to the placement position by reverse rotation at 1/3 rotation deceleration, the bait 6 is thrown at the reference throwing angle. Bait and A
The feeding cycle in the high-efficiency state of the C servomotor 11 is shortened so that a margin time is provided to reduce the fatigue of the crew. Further, by providing a danger prevention frame 22 having a shape in contact with the upper surface of the upper cover 17 of the AC servomotor 11 to cover the flat portion of the feeding arm 21 before feeding, danger to crews is prevented. be able to.

[0034]

As described above in detail, according to the feeder according to the present invention, the feeding arm is stopped at a predetermined rotation angle and rotation speed by the rotation force of the AC servomotor , and then suddenly stopped. By doing so, it becomes possible to feed the bait loaded on the fishhook far away from the hull, and it is possible to perform bait in a good rope condition. And when feeding automatically,
Switch the automatic change-over switch to the automatic side, and the crew attaches the branch line to the trunk line based on the signal of the throwing indicator, and places the bait on the fishing hook on the bait arm. Just by doing, the control output signal is issued from the controller based on the feeding start signal from the automatic feeding controller and the AC servo motor for feeding is rotated, so even if the feeding cycle becomes longer, it is manual work There is a great effect that the physical and mental burden on the crew is reduced as compared with the feeding work based on the crew.
That is, the signal from the lasso indicator for attaching the branch line to the trunk line
In conjunction with the signal, the bait loaded on the hook can be automatically fed into the sea.

[0035] Toesa is a rotation of Soesaude by the rotational force of the AC servo motor, the reference position of about 120 degrees Soesaude is relative to the ship center line by a sudden stop of Soesaude by sudden stopping of the AC servomotor The feeding arm is returned to the feeding position after a predetermined stop time set in the controller elapses, so that it is assumed that the feeding arm has various lengths. Even if there is a strong wind or a gust of wind, there is no problem that the feeding arm is entangled with the branch line that is extended outboard.

Therefore, according to the present invention, a baiting operation such as rope formation, entanglement, damage to seabirds, baiting, baiting distance, baiting to a long distance, work efficiency, baiting cycle, burden on workers, etc. Each item can be improved in many ways.
