BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fishing machine used for, for example, squid fishing on a fishing boat, and more particularly to an automatic fishing machine in which a braking mechanism attached to a driving device for rotating a winding drum for fishing line is improved. The present invention relates to a fishing line winding device for a machine.

[0002]

2. Description of the Related Art An automatic fishing machine comprises a winding drum on which a fishing line is wound and a driving device for rotating the drum. A tackle such as a weight or a fishing hook is attached to the end of the fishing line. When the fishing line is fed out of the winding drum to a predetermined depth by the driving device, a hiccup movement is given to the fishing line. At this time, a catch such as squid is caught by a hook attached to the fishing line, and the fishing line is wound around a drum.
In this automatic fishing machine, when the fishing line is completely wound on the winding drum, it is necessary to apply a braking force so that the drum is not rotated by the weight of the weight and the game such as squid.

FIG. 7 shows a fishing line winding device of a conventionally known automatic fishing machine. In this figure, a pinion gear 32 in a main body case 31 attached to an output shaft of a motor 30 meshes with an intermediate gear 34 of an intermediate shaft 33, and a pinion gear 35 of the intermediate shaft 34 is connected to a gear 37 of a drive shaft 36. Are engaged. These gears 32, 34, 35, 37 constitute a two-stage reduction mechanism. A winding drum 38 is attached to an end of a drive shaft 36 extending from the main body case 31 to the outside, and the rotation of the motor 30 causes the winding drum 38 to rotate at a reduced speed. The intermediate gear 34 has a friction clutch plate 39

That is, the curl 45 a at the tip of the piano wire 45, which is urged clockwise in the drawing and is wound around the outer periphery of the holding pulley 44 fixed to the ratchet gear 40, projects to the side surface of the ratchet pawl 41. It is designed to engage with the pins 46 and 47. A torque spring 48 for pressing the clutch plate 39 is attached to the intermediate gear 34 on the opposite side of the ratchet gear as shown in FIG.
A plurality of holes 49 for adjusting the pressurizing torque are provided in the outer peripheral surface portion.

[0004] In the driving device configured as described above, when the motor 30 is rotated counterclockwise, the ratchet gear 40 is rotated.
Although the ratchet pawl 41 is engaged with the clutch, the clutch plate 39 slides, so that the drive shaft 36 rotates counterclockwise and the fishing line is paid out from the drum 38. When the motor 30 is rotated in the clockwise direction, the curled portion 45a of the piano wire 45 engages with the pin 46 to lift the ratchet pawl 41 so that the ratchet gear 40

When the drive shaft 36 tries to rotate counterclockwise while the motor is stopped, the ratchet pawl 41 is engaged with the ratchet gear 40 by the spring 43 as shown in FIG. The drive shaft 36 is locked in the stopped state by the frictional force of the plate 39. With this, the fishing line is completely wound up,
When the motor 30 is stopped, the fishing line is not lowered because the drum 38 is locked even if the fishing line is to be fed by its own weight such as a weight. Also, if a force is applied to turn the drive shaft 36 clockwise while the motor 30 is stopped, the ratchet pawl 41 comes off (FIG. 8).
The drum 38 can freely rotate clockwise.

[0005]

In the above-mentioned conventional fishing line winding device of an automatic fishing machine, a one-way clutch mechanism including a ratchet gear 40, a ratchet pawl 41, a holding pulley 44, a piano wire 45, and the like, and a friction clutch plate are provided. It is necessary to assemble a braking mechanism consisting of the torque spring 39 and the torque spring 48 to the intermediate shaft 33, and the mechanism is complicated, so that the assembly of the device cannot be easily performed and the maintenance is difficult.

The present invention has been proposed in order to solve such problems of the prior art, and has a simple structure and can be easily assembled and adjusted. The purpose is to provide.

[0007]

In order to achieve this object, a fishing line winding device for an automatic fishing machine according to the present invention is provided with a winding shaft for a fishing line attached to a drive shaft extending out of a main body case, and a rotational force of a motor. Is transmitted to the drive shaft via a speed reduction mechanism housed in the main body case to rotate the winding drum, and the non-excitation operation is performed so that the axis is inserted into either the drive shaft or the rotation shaft of the speed reduction mechanism. The stator of the electromagnetic brake is fixed to the body case, and the rotation is stopped by the braking force when the power is stopped.
A one-way clutch that can lock the rotation of the winding drum in the fishing-line feeding direction is fitted, and the rotor is coupled to the drive shaft or the rotation shaft via the one-way clutch. The excitation operation type electromagnetic brake is operated.

[0008]

According to the above construction, when the motor is energized, the non-excited operation type electromagnetic brake is also energized.
Since the braking force of this brake does not work and the rotor is free, the shaft connected to the one-way clutch can rotate in either direction. Therefore, the torque of the motor is transmitted to the drive shaft via the speed reduction mechanism, and the winding drum is rotated in both forward and reverse directions. On the other hand, when the energization of the motor is stopped, the energization of the non-excited operation type electromagnetic brake is also stopped, so that the braking force acts to stop the rotation of the rotor, and the one-way clutch acts to couple to the one-way clutch. The rotation of the rotating shaft in the direction in which the fishing line is paid out is locked. Thereby, the rotation of the winding drum in the fishing line payout direction is locked, and it is possible to prevent the fishing line from being pulled out from the drum by its own weight such as the weight.
