The power is transmitted to the rotation shaft 20 via a second transmission mechanism 17b composed of a gear. 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 for turning on / off the transmission of power by an electromagnetic force generated by energizing the coil, and various known structures can be applied.

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

As shown in FIG. 3, the control unit 15 includes an input unit 15a including a keyboard or a liquid crystal touch panel, a display unit 15b including 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 calculating means 15f for calculating the rotation speed of the rotary drum 30 from the output signal of the rotary drum 20 and the output signal of the rotation detector 14 to determine whether the rotary drum 30 is rotating in the hoisting direction (forward rotation) or not. The rotation direction discriminating means 15g for discriminating the rotation direction of the rotating drum 30 to determine whether the rotation is the rotation of the rotating drum 30 (reverse rotation), and the rotation direction discriminating means 15g determines that the rotating drum 30 is rotated in the lowering direction. Necessary to maintain the rotation speed at a predetermined rotation speed based on the rotation speed obtained from the rotation speed calculation means 15f. The applied voltage change calculating means 15h for calculating a change in the applied voltage to the electromagnetic clutch 13 to be applied, and the change in the applied voltage calculated by the applied voltage change calculating means 15h with respect to a preset applied voltage. It is provided with an applied voltage adjusting means 15i for adjusting the applied voltage by increasing or decreasing and an extension distance calculating means 15j for calculating a distance of the fishing line extended per unit time.

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

When it is determined that the rotating drum 30 has been rotated in the reverse direction, the applied voltage change calculating means 15h determines, based on the obtained rotation speed, an electromagnetic clutch required to maintain the fishing line lowering speed at a predetermined value. 13 is calculated. For example, the applied voltage change calculator 15h calculates a product of the rotation speed obtained from the rotation speed calculator 15f and a predetermined constant corresponding to the rotation speed as a change in the applied voltage to the electromagnetic clutch 13. Is made.

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

The control unit 15 is a case where the rotation direction determination unit 15g determines that the rotating drum 30 is rotating in the lowering direction, and the rotation speed obtained from the rotation speed calculation unit 15f is lower than the predetermined rotation speed. In this case, the drive drum 12 drives the rotary drum 30 in the lowering direction, and when the rotation speed of the rotary drum 30 becomes equal to or higher than a predetermined rotation speed, the drive motor 12 is controlled to stop. The control unit 15 connects the electromagnetic clutch 13 when it is determined that the rotating drum 30 is rotating in the lowering direction and when the rotating speed of the rotating drum 30 is lower than a predetermined rotating speed. When the rotation speed of the rotating drum 30 becomes equal to or higher than a predetermined rotation speed, the control is performed so that the electromagnetic clutch 13 is disconnected.

The control unit 15 can automatically set the coupling torque of the electromagnetic clutch 13 to the coupling torque in 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 an operator. In the case where the rotation is performed manually, the connection torque of the electromagnetic clutch 13 is gradually increased from zero in a state where the drive motor 12 is rotated so that the rotation drum 30 rotates in the unwinding direction. 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 rotating the rotary shaft 20 reciprocally in the axial direction as an ear swing mechanism. The moving drive mechanism 16 is rotationally driven by the drive motor 12 via a first transmission mechanism 17a and a second transmission mechanism 17b, and includes a drive shaft 19 provided in parallel with the rotation shaft 20, and a surface of the drive shaft 19. And a helical groove 18a that reciprocates in the axial direction of the drive shaft 19, is mounted on the rotary shaft 20 of the rotary drum 30, and is mounted on the rotary shaft 20 so as not to move in the axial direction of the rotary shaft 20. A claw member 18b fitted along the spiral groove 18a and guided along the spiral groove 18a when the drive shaft 19 rotates. By adopting such a movement driving mechanism 16, it is possible to prevent the fishing line 40 from being biased to one place (thickening), and to prevent the fishing hooks from becoming entangled with each other. Further, it is possible to prevent the calculation of the winding length from being inaccurate due to a change in the diameter of the portion to be wound.

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

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

回転 As shown in FIG. 4, the rotating drum 30 is configured by a pair of

half drum members

30a and 30b integrally formed of a resin material, which are coaxially connected to each other. Each of the pair of

half drum members

30a and 30b has a main body 31 having a through hole 31a at the center of which the rotary shaft 20 is inserted, a bobbin trunk 32 located on the outer peripheral portion of the main body 31, A flange portion 33 provided on an outer peripheral portion of one end of the body portion 32 in the axial direction. A pair of

half drum members

30a and 30b are connected to each other by fixing the other ends of the main body 31 in the axial direction to each other. The pair of

half drum members

30a and 30b is connected using a plurality of screws 34 on the outer peripheral portion of the main body 31. As the resin material, vinyl chloride, carbon fiber reinforced resin, or the like can be used.

As described above, in the fishing machine 100 of the present embodiment, the rotating drum 30 is located on the outer peripheral portion of the main body 31 having the through hole 31a into which the rotary shaft 20 is inserted at the center. The bobbin trunk 32 and a flange 33 provided on one end side of the bobbin trunk 32 are formed by connecting the main bodies of a pair of half-

drum members

30a and 30b integrally formed of a resin material back to back. ing.

Thus, the weight and strength of the rotating drum 30 can be reduced. Further, the number of mounting screws can be reduced as compared with the conventional rotating drum, which contributes to a reduction in inertial force as a rotating body, and makes it easy to turn and stop. In addition, since the rotating shaft 20 is fixed to the rotating shaft 20 at the center position of the rotating drum 30, the length of the rotating shaft 20 can be shortened, which contributes to the reduction in the weight of the fishing boat as a whole, and the steering stability and fuel efficiency of the fishing boat. Can be expected to improve. In addition, since the rotating drum 30 is fixed to the rotating shaft 20 at one position in the center, the fixing operation and the removing operation are facilitated, and the convenience is improved.

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

As shown in FIG. 6, the rotary drum 30A has a main body 31A having a through hole 31a in the center of which the rotary shaft 20 is inserted, a bobbin trunk 32A located on the outer periphery of the main body 31A, and a bobbin trunk 32A. A flange portion 33A provided at one end of the portion 32A is formed by connecting the body portions 31A of a pair of

half drum members

30a and 30b integrally formed of a resin material back to back. The pair of

half drum members

30a and 30b are connected by screws 34 on the outer peripheral portion of the main body 31. When such a diamond-shaped rotary drum 30A is used, even if the drum itself is rotating at a constant speed when the drum is lowered, the falling speed of the fishing line is fluctuated and this results in a shaking operation. The incentive effect can be obtained automatically. Moreover, weight reduction and high strength can be achieved. The fishing machine using the rotating drum 30A has been mounted on a test boat (18th Takakimaru) and various experiments have been conducted since the end of April, 2018.

The present invention is not limited to the above-described embodiment, but includes various modified forms within the technical scope without departing from the spirit of the invention described in the appended claims.

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