  The present invention relates to a hoisting / lowering speed control device in a fishing line winder that can detect the position, speed, and current load by a servo motor and control the rotational speed and torque of the circular drum in the fishing line winder. The purpose is to provide.

For this purpose, the hoisting / lowering speed control device in the fishing line take-up device of the present invention is mounted on a fishing boat, and a cylindrical circular drum for hoisting / lowering the fishing line and the take-up shaft of the circular drum via a gear mechanism. It comprises a fishing machine main body equipped with a servo motor that is directly driven, and a control device that controls the rotational speed and shaft torque of the circular drum based on the position and speed signals of the servo motor and the current load.
Further, the control device compares the load value during operation with a predetermined load value or increase / decrease of the current load sampled during operation, so that the drum rotation speed is higher than the free fall speed of the weight during lowering. Slowly detect that the lowering load has increased from the load obtained in advance by sampling and control the deceleration to prevent the wire from loosening, prevent the wire from coming off the front roller, and When the tension tends to increase due to rolling or fishing results, decrease the rotational speed or torque to suppress the tension, and to increase the tension when the tension tends to decrease due to prevention of breakage of fishing gear or rolling or swelling of the ship. By controlling in this manner, the speed and torque are corrected so that the fish being picked up is not missed.
Furthermore, by using a servo motor for direct drive and using a circular drum, it is possible to repeat acceleration / deceleration during one cycle of shaking, and each acceleration / deceleration time and maximum / minimum speed can be set individually. The “synthetic shackle” is created.

Thus, the hoisting / lowering speed control device in the fishing line take-up device of the present invention is driven directly by a servo motor without using a clutch on the take-up shaft. By omitting the sprocket shaft and simplifying the mechanism, it is possible to reduce mechanical friction, increase the efficiency of output, and realize a reduction in size and weight.
In addition, since the squid ship is equipped with a plurality of winding devices, it can be expected to improve fuel efficiency and reduce the risk of overturning by securing a space on board and reducing cargo by reducing the size and weight.

The control device of the present invention compares the load value during operation with a predetermined load value or an increase or decrease in current load sampled during operation.
(1) At the time of lowering, the drum rotation speed exceeds the free fall speed of the weight, and when the lowering load is subtly decreased, the wire is removed from the front roller by instantaneously detecting that the lowering speed is reduced. When the drum rotation speed is lower than the free fall speed and the lowering load senses the weight, the speed increase control can be immediately performed to return to the set speed.
(2) When a load close to the set strength limit of the fishing gear is applied at the time of hoisting, the hoisting speed reduction control or hoisting torque reduction control is executed to prevent the fishing gear from being damaged and to prevent the fish being caught from escaping. To do.
(3) When the hull is subject to rolling or pitching due to wind or waves, or when the fishing line tension tends to increase due to healing that lifts and lowers the entire hull due to swell, etc., increase the tension. When the fishing line tension tends to decrease and the fishing line tension tends to decrease, the speed is increased and the fishing line is sufficient to disengage from the front roller or the fish being lifted off. To prevent.

  In addition, since the present invention uses a servo motor for direct drive and uses a circular drum, the rotation shaft itself can be repeatedly accelerated and decelerated during a single stroke stroke, thereby reproducing the diamond drum shackle. In addition, the maximum speed, minimum speed, and stroke of each acceleration / deceleration repeated within a single stroke stroke can be set individually to reproduce the unprecedented combined brush stroke behavior. It has become possible.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a front view of a squid fishing fishing boat 1 as viewed from the direction of travel. The squid fishing fishing boat 1 has a bridge 2 in the center and a circular circular drum 5 for winding fishing lines 4 on both sides of the hull 3 at equal intervals. And a front roller 8 that projects from the sink 7 and guides the fishing line 4 to the sea side of the fishing machine body 6.
As shown in FIG. 2, the fishing machine main body 6 has a servo motor (not shown) disposed inside the housing 9 and is directly wound around the output shaft of the servo motor (not shown) via a gear mechanism. A shaft 10 is connected, and a circular drum 5 for winding the fishing line 4 is fixed to both ends of the winding shaft 10.
The circular drum 5 is not a conventional rhombus drum but a circular drum as shown in FIG.

As shown in FIG. 3, in the fishing machine main body 6, a servo motor 11 that directly drives the winding shaft 10 of the circular drum 5 via a gear mechanism, and a control device that controls the driving of the servo motor 11. 12 is provided.
The control device 12 receives the detected values of the position and speed detected by the speed sensor 13 and the position sensor 14 provided on the rotating shaft of the servo motor 11.
The power source 15 is an AC / DC power source from a generator or the like.
In addition, a current sensor 16 is provided on an input wire to the servo motor 11, and a current load of the servo motor 11 is input to the control device 12.

Further, the control device 12 stores an empirical shackle by hand fishing at the time of winding / lowering as a standard value in advance.
For example, as shown in FIG. 4, it is lowered from the sea surface at the first lowering speed to the first lowering water depth at the lowering speed of the needle portion, subsequently at the second lowering speed to the second lowering water depth, and further at the second lowering speed. Lower the speed to enter the school of fish at the third lowering speed from the lowering water depth, lower the speed, and when reaching the set water depth, let the weight settle down and have a waiting time to start shackles.
Next, after having given a predetermined stagnation time, start the scribing and repeat the high speed hoisting speed and the low speed hoisting speed in sequence, that is, when the shackle 1 to the shackle 3 are repeated until the total water depth is reached, the first raising speed is reached. Winding up at a high speed up to the water depth, followed by winding up at the second raising speed to the second raising water depth at the needle part raising speed, and then at the third raising speed up to the sea surface at the weight raising speed.

Then, the control device of the present invention compares the load value during operation with a predetermined load value or increase / decrease of the current load sampled during operation, so that the rotation speed of the drum can be freely adjusted during the lowering. When the rotational speed exceeds the falling speed and the rotational force due to falling weight stops working, it is immediately detected that the lowering load has increased slightly, and the lowering speed is controlled to reduce the speed, and the drum rotational speed becomes lower than the free falling speed. When the lowering load senses the weight, feedback control is performed to immediately return to the set speed by controlling the speed increase.
Further, when the needle is entangled during the lowering and the load exceeds a set value, the circular drum is stopped and an alarm device is provided to issue an alarm and notify the operator.
In addition, when a load close to the set strength limit of the fishing gear is applied to the circular drum during winding, the tension control is performed by controlling the decrease in the winding speed as the motor load increases or by controlling the decrease in the winding torque. Do.
In addition, when the hull is subject to rolling or pitching due to wind or waves, or when the fishing line tension tends to increase due to healing that lifts and lowers the entire hull due to swell, etc., increase the tension of the motor. Tension control is performed by sensing speed as an increase in load and performing deceleration control, or when the fishing line tension tends to decrease, increasing speed control.

  In addition, the present invention uses a servo motor for direct drive and a circular drum, thereby enabling the rotary shaft itself to repeat acceleration and deceleration during a single stroke stroke, thereby reproducing the diamond drum shackle. In addition, the maximum speed, minimum speed, and stroke of each acceleration / deceleration repeated within a single stroke stroke can be set individually to reproduce the unprecedented combined brush stroke behavior. It has become possible.

That is, as shown in FIG. 5 (a), since the prior art uses a rhombus drum, the stroke of the shackle is fixed. However, as shown in FIG. Since the motor is used and a circular drum is used, the acceleration / deceleration time and maximum / minimum speed of the shackle can be set individually, so that a small stroke or a large stroke can be set freely.
As shown in FIG. 6, the stroke of the shank is fixed because the length of one round of the rhombus drum is fixed, but since the present invention uses a circular drum, it moves like changing the size of the rhombus drum, That is, it is possible to freely carry out fine shackles with a small drum or long strokes with a large drum.
