A first transmission mechanism 17a composed of gears with which the driving force of the drive motor 12 is meshed, an electromagnetic clutch 13 and a meshed gear. The power is transmitted to the rotating shaft 20 via a second transmission mechanism 17b composed of gears. Also, the rotation detector 14 is connected to the drive shaft 19 via a third transmission mechanism 17c composed of a chain and a sprocket.

The electromagnetic clutch 13 is a clutch that turns power transmission on and off by means of an electromagnetic force generated by energizing a coil, and various known configurations are applicable.

The rotation detector 14 is a rotary encoder that detects the rotation speed and rotation direction of the rotary shaft 20 and thus of the rotary drum 30 .

As shown in FIG. 3, the control unit 15 includes an input unit 15a such as a keyboard or a liquid crystal touch panel, a display unit 15b such as a liquid crystal display or a liquid crystal touch panel, a CPU 15c, a ROM 15d, a RAM 15e, and a rotation detector 14. and a rotation speed calculation means 15f for calculating the rotation speed of the rotary shaft 20 and therefore the rotation speed of the rotary drum 30 from the output signal of the rotation detector 14. When it is determined that the rotation of the rotating drum 30 is in the lowering direction by the rotating direction determining means 15g for determining the rotating direction of the rotating drum 30, i.e., whether it is rotating in the direction (reverse rotation). , applied voltage change calculation means for calculating a change in the voltage applied to the electromagnetic clutch 13 required to keep the rotation speed at a predetermined rotation speed, based on the rotation speed obtained from the rotation speed calculation means 15f; 15h, applied voltage adjustment means 15i for adjusting the applied voltage by increasing or decreasing the change in the applied voltage calculated by the applied voltage change calculation means 15h with respect to the preset applied voltage, and fishing line unit time. and a pay-out distance calculation means 15j for calculating the distance paid out for a win.

The CPU 15c controls the overall operation of the fishing machine 100 according to the control program stored in the ROM 15d, using the RAM 15e as a work area.

When it is determined that the rotating drum 30 is rotating in the reverse direction, the applied voltage change amount calculating means 15h calculates an electromagnetic clutch required to keep the fishing line lowering speed at a predetermined value based on the obtained rotational speed. 13 is configured to calculate the amount of change in the applied voltage. For example, the applied voltage change calculation means 15h calculates the product of the rotation speed obtained from the rotation speed calculation means 15f and a predetermined constant corresponding to this rotation speed as the change in the voltage applied to the electromagnetic clutch 13. made to

The applied voltage adjustment means 15i adds or subtracts the applied voltage change calculated by the applied voltage change calculation means 15h to or from a predetermined voltage set value (or hoisting force set value) for driving the electromagnetic clutch 13. is applied to the electromagnetic clutch 13.

Based on the detection result of the rotation detector 14, the pay-out distance calculation means 15j calculates the distance by which the fishing line is paid out per unit time when the rotary drum rotates in the lowering direction.

The control unit 15 determines that the rotation speed obtained from the rotation speed calculation unit 15f is less than a predetermined rotation speed when the rotation direction determination unit 15g determines that the rotary drum 30 is rotating in the lowering direction. In this case, the rotating drum 30 is driven in the lowering direction by the driving motor 12, and when the rotational speed of the rotating drum 30 exceeds a predetermined rotational speed, the driving motor 12 is controlled to stop. Further, when it is determined that the rotating drum 30 is rotating in the lowering direction and the rotating speed of the rotating drum 30 is less than the predetermined rotating speed, the control unit 15 connects the electromagnetic clutch 13 . , the electromagnetic clutch 13 is controlled to be disconnected when the rotation speed of the rotary drum 30 exceeds a predetermined rotation speed.

Further, the control unit 15 can automatically set the connection torque of the electromagnetic clutch 13 to the connection torque of the clutch assist operation mode. The setting of the coupling torque in the clutch assist operation mode may be automatically performed by the control unit 15 as described later, or may be manually performed by the operator. In the manual operation, the connection torque of the electromagnetic clutch 13 is gradually increased from zero while the driving motor 12 is rotated so that the rotating drum 30 rotates in the lowering direction, and the torque when the rotating drum 30 starts to rotate is increased. The torque value is set in the electromagnetic clutch 13 as the coupling torque for the clutch assist operation mode.

The movement drive mechanism 16 is configured to rotate while reciprocating the rotary shaft 20 in the axial direction as a swivel mechanism. The movement drive mechanism 16 is rotationally driven by the drive motor 12 via a first transmission mechanism 17a and a second transmission mechanism 17b. and a spiral groove 18a that reciprocates in the axial direction of the drive shaft 19, and is mounted on the rotating shaft 20 of the rotating drum 30, and is mounted on the rotating shaft 20 so as not to move in the axial direction of the rotating shaft 20, and a pawl member 18b that is fitted into the spiral groove 18a and guided along the spiral groove 18a when the drive shaft 19 rotates. By adopting such a movement drive mechanism 16, it is possible to prevent the fishing line 40 from being concentrated in one place (winding thick), and to prevent the hooks from entangling with each other. In addition, it is possible to prevent inaccurate calculation of the length to be wound due to a change in the diameter of the wound portion.

The rotary shaft 20 is provided so as to pass through the housing 11 of the fishing machine body 10, as shown in FIGS. Rotating drums 30 are attached to both ends of the rotating shaft 20, respectively.

In this embodiment, the rotating drum 30 is a drum in which a winding portion 31 around which fishing line is wound has a circular axial cross-sectional shape. The fishing line 40 is wound up or lowered by rotating the rotary drum 30 in an appropriate direction by the fishing machine main body 10 . A fishing line 40 is attached with a fishing hook with artificial bait such as a branch hook or a connecting hook. A weight 50 is attached to the tip of the fishing line 40 .

As shown in FIG. 4, the rotary drum 30 is constructed by coaxially connecting a pair of half-drum members 30a and 30b integrally molded of a resin material. Each of the pair of half-drum members 30a and 30b includes a main body portion 31 having a through hole 31a in which the rotating shaft 20 is inserted, a bobbin trunk portion 32 positioned on the outer periphery of the main body portion 31, and a bobbin drum portion 32. A flange portion 33 is provided on the outer peripheral portion of one axial end of the body portion 32 . A pair of drum half members 30a and 30b are connected to each other by fixing the other axial ends of the body portion 31 to each other. The pair of half-drum members 30a and 30b are connected using a plurality of screws 34 on the outer periphery of the body portion 31. As shown in FIG. Vinyl chloride, carbon fiber reinforced resin, or the like can be used as the resin material.

As described above, in the fishing machine 100 of the present embodiment, the rotary drum 30 includes the main body portion 31 having the through hole 31a in which the rotating shaft 20 is inserted, and the outer peripheral portion of the main body portion 31. A bobbin trunk portion 32 and a flange portion 33 provided at one end of the bobbin trunk portion 32 are formed by connecting body portions of a pair of half drum members 30a and 30b integrally molded from a resin material back to back. ing.

As a result, it is possible to reduce the weight and increase the strength of the rotating drum 30 . In addition, the number of mounting screws can be reduced compared to the conventional rotating drum, and the rotating body contributes to reducing the inertial force, making it easier to rotate and stop. In addition, since the rotating drum 30 is fixed to the rotating shaft 20 at the center position, the length of the rotating shaft 20 can be shortened, which contributes to the weight reduction of the entire fishing boat, and the steering stability and fuel efficiency of the fishing boat. can be expected to improve. Moreover, since it is fixed to the rotary shaft 20 at one point in the center of the rotary drum 30, fixing and removing operations are facilitated, and convenience is improved.

In addition, in the fishing machine 100 of the embodiment described above, an example in which the rotary drum 30 has a circular axial cross-sectional shape has been described, but the present invention is not limited to this. For example, as in a rotating drum 30A shown in FIG. 6, the axial cross-sectional shape may be rhomboid.

As shown in FIG. 6, the rotating drum 30A includes a main body portion 31A having a through hole 31a in which the rotating shaft 20 is inserted, a bobbin drum portion 32A positioned on the outer circumference of the main body portion 31A, and a bobbin drum portion 32A. A flange portion 33A provided at one end of the portion 32A is formed by connecting back-to-back body portions 31A of a pair of half drum members 30a and 30b integrally molded from a resin material. A pair of half-drum members 30a and 30b are connected by screws 34 at the outer periphery of the body portion 31 thereof. When such a diamond-shaped rotating drum 30A is used, even if the drum itself rotates at a constant speed when the drum 30A is lowered, the falling speed of the fishing line fluctuates, resulting in a jerking motion. You can get the trigger effect automatically. Also, it is possible to reduce the weight and increase the strength. Since the end of April 2018, the fishing machine using this rotating drum 30A has been mounted on a test ship (Ryuki Maru No. 18) to conduct various experiments.

The present invention is not limited to the above-described embodiments, but includes in its technical scope various design-changed forms within the scope that does not deviate from the gist of the invention described in the claims.

INDUSTRIAL APPLICABILITY The present invention can be applied to a fishing machine mounted on a ship and having a rotating drum for hoisting and hoisting fishing line.
