Description

  In the present invention, when the rotating drum rotates in the winding direction, the voltage applied to the electromagnetic clutch is controlled to keep the tension applied to the fishing line at a predetermined value so that the amount of fishing line fed is not unnecessarily fed. The present invention relates to a fishing machine and a control method thereof.

  Conventionally, a fishing machine, for example, a tuna fishing machine, after feeding a fishing line into the sea, the drive motor always rotates in the winding direction, and the applied voltage to the electromagnetic clutch is set constant, so that the load applied to the fishing line The rotational speed of the rotating drum changes. If the fishing line is pulled stronger and faster by the fish, the rotating drum may rotate in the reverse direction.

  Further, a small fishing reel provided with a yarn tension measuring device has been proposed (see, for example, Patent Document 1).

  In this case, a spool that is rotatably supported by the reel body via a spool shaft, a drag device that applies a drag force to the spool, and a stand unit that detachably supports the reel body on the fishing rod are provided. In a fishing reel, the stand part is configured as a two-layer plate with one plate and the other plate, one plate is fixed to the reel body, the other plate is fixed to the fishing rod and slidable with the one plate And a bending beam provided so as to convert the tension applied to the fishing line into a deflection amount between the two-layer plates, a measuring means for measuring the deflection amount applied to the deflection beam, and the two-layer from the deflection amount. The calculation means comprises a calculation means for calculating the force applied between the plates, and a display means for displaying the yarn tension value calculated by the calculation means.

  When tension is applied to the fishing line wound around the spool in the feeding direction, the spool is pulled in that direction, the one plate of the stand portion is moved, and the flexible beam is bent. Then, the amount of deflection is measured by the measuring means, and then the tension applied between the two layers is calculated by the calculating means. Since the calculated value is displayed by the display means, the angler only needs to tighten the star drag and use the reel so that the displayed value is within the maximum tension value of the fishing line. Thereby, the angler can perform effective fishing without relying on intuition.

  However, because tuna has the habit of quickly intruding deep into the sea when eating, the conventional tuna fishing machine has a rotating drum when the fishing line is pulled by the fish at a high speed. A large amount of fishing line is unwound due to inertia, and the fishing line is bent. In this case, when the fishing line is further pulled by the boat traveling or when the fish such as a tuna is further pulled, there is a problem that a large tension is applied instantaneously, the fishing line is easily broken, and a risk that the fish escapes occurs.

  Further, in the case of Patent Document 1, when fishing, the angler needs to tighten the star drag so that the displayed tension value is within the maximum tension value of the fishing line. In case it is not applicable.

  Therefore, in the present invention, when the rotating drum rotates in the winding direction, the applied voltage to the electromagnetic clutch is controlled to maintain the tension applied to the fishing line at a predetermined value, and the amount of fishing line fed out is more than necessary. An object of the present invention is to provide a fishing machine and a control method thereof.

A fishing machine comprising an electromagnetic clutch, comprising: a rotation detector that detects a rotation speed and a rotation direction of the rotating drum; and a control unit that controls the electromagnetic clutch based on a detection result of the rotation detector, A control unit that calculates a rotation number of the rotating drum from an output signal of the rotation detector; a rotation direction determination unit that determines a rotation direction of the rotating drum from the output signal of the rotation detector; When it is determined by the rotation direction determination means that the rotation drum has rotated in the winding direction, the fishing line is squeezed based on the rotation speed obtained from the rotation speed calculation means. An applied voltage change calculation means for calculating a change in applied voltage to the electromagnetic clutch required to maintain the tension at a predetermined value, and an applied voltage change calculation means based on a preset applied voltage. Application voltage adjusting means for adjusting the applied voltage by increasing or decreasing the applied voltage change.

  For example, the applied voltage change calculation means calculates the product of the rotation speed obtained from the rotation speed calculation means and a predetermined constant corresponding to the rotation speed as a change in the applied voltage to the electromagnetic clutch. To be made.

A method for controlling a fishing machine comprising an electromagnetic clutch for transmitting to a rotating drum and a rotation detector for detecting the rotation speed and rotation direction of the rotating drum, wherein the rotation speed of the rotating drum is determined from an output signal of the rotation detector. When the rotational direction of the rotating drum is further determined and it is determined that the rotating drum has been rotated in the reverse direction of the lowering direction, the tension applied to the fishing line is set to a predetermined value based on the calculated rotational speed. An applied voltage obtained by calculating a change in the applied voltage to the electromagnetic clutch necessary for maintaining, and adding or subtracting the calculated applied voltage change to a preset applied voltage And controlling so as to keep the tension applied to the fishing line is applied to the electromagnetic clutch to a predetermined value.

  For example, the amount of change in the applied voltage to the electromagnetic clutch is calculated by the product of the obtained rotation speed and a predetermined constant corresponding to the rotation speed.

  In the present invention, when fishing, the control unit calculates the rotational speed of the rotating drum from the output signal of the rotation detector, further determines the rotating direction of the rotating drum, and the rotating drum rotates in the winding direction (reverse).

Control is performed to keep the tension applied to the fishing line at a predetermined value by applying to the electromagnetic clutch an applied voltage obtained by adding or subtracting the change in applied voltage to a preset applied voltage.

  As a result, when the fishing line is pulled by the fish during fishing, that is, when the rotating drum rotates in the lowering direction (reverse rotation), the tension applied to the fishing line is applied to the electromagnetic clutch to keep it at a predetermined value. It becomes possible to control the voltage to prevent the fishing line from being fed out more than necessary. Therefore, it is possible to eliminate the risk that the fish will escape due to the break of the fishing line.

  Further, since a method of detecting the rotation direction of the rotating drum from the output signal of the rotation detector is used, a simple configuration can be achieved and the cost can be reduced.

Further, since a method of detecting the rotation direction of the rotary drum from the output signal of the rotation detector is used, a simple configuration can be achieved and the cost can be reduced.

Hereinafter, a fishing machine and a control method thereof according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of a fishing machine as an embodiment. FIG. 2 is a cross-sectional view taken along line AA showing the positional relationship between the axes of the fishing machine 100. In FIG. 2, the rotating drum 60, the ring 5 and the roller 6 are omitted. FIG. 3 is a diagram showing an installation state of the fishing fishing machine 100. FIG. 4 is a block diagram showing a control system of the fishing machine 100.

  As shown in FIGS. 1 to 3, the fishing machine 100 includes a drive motor 10 disposed in the main body case 1, an electromagnetic clutch 20 that transmits rotation of the drive motor, an encoder 30 as a rotation detector, and a control unit. 40, a drum mounting shaft 50, and a rotating drum 60.

  The main body case 1 is provided with an attachment base 2 for attachment to a ship, a rotatable fixture 3, and a tightening lever 4. A drive motor 10 is installed in the lower part of the main body case 1, and the driving force of the drive motor 10 is transmitted to the input shaft of the electromagnetic clutch 20 via the chain 11 via the transmission 10 a. The output shaft of the electromagnetic clutch 20 is connected to the drum mounting shaft 50 by a chain 21. The rotary drum 60 around which the fishing line 61 is wound is fixed to the drum mounting shaft 50. The fishing line 61 is fed out to the sea through the ring 5 and the roller 6. Further, the output shaft of the electromagnetic clutch 20 is connected to the input shaft of the encoder 30 by a chain 31.

  For example, a powder clutch is used as the electromagnetic clutch 20. The electromagnetic clutch 20 is filled with fine iron powder between the rotor on the driving side and the driven side, and the rotor portion can be magnetized from the outside by an electromagnet. When the clutch is disengaged, the rotors are not in contact with each other, so power transmission is not performed. However, when the rotor is magnetized, powder (fine iron powder) is sucked into the gap between the rotors, filling the gap. It is a mechanism for transmitting power. In this type of clutch, the transmitted torque can be finely controlled by adjusting the magnetic force. The electromagnetic clutch 20 is not limited to a powder clutch.

  The encoder 30 is a rotary encoder as a rotation detector that detects the rotation speed and rotation direction of the rotary drum 60. Based on the output signal of the encoder 30, the rotational speed of the rotary drum 60 can be calculated, and the rotational direction of the rotary drum 60 can be detected and determined.

  The control unit 40 controls the operation of the fishing machine 100. As shown in FIG. 3, the control unit 40 includes an input unit 41, a display unit 42, a CPU 43, a ROM 44, a RAM 45, a rotation number calculation unit 46, a rotation direction determination unit 47, and an applied voltage change calculation. Means 48 and applied voltage adjusting means 49 are provided.

  As shown in FIG. 4, the output signal of the encoder 30 is supplied to the rotation speed calculation means 46 and the rotation direction determination means 47. The applied voltage adjusted by the applied voltage adjusting means 49 is applied to the electromagnetic clutch 20.

  In addition, after feeding the fishing line to the sea via the input means 41, the initial voltage applied to the electromagnetic clutch 20 that always drives the rotary drum 60 in the forward rotation direction so that the fishing line is always under a constant tension. A set value or the like can be input. Since the tension applied to the fishing line varies depending on the water depth, the initial setting value of the applied voltage is set so that a predetermined tension is always applied to the fishing line. Moreover, the display means 42 can display an operation state, an initial setting value, and the like.

  The rotation speed calculation means 46 is configured to calculate the rotation speed of the rotary drum 60 based on the output signal of the encoder 30. The rotation direction discriminating means 47 discriminates whether the rotating drum 60 rotates in the winding direction (forward rotation) or rotation in the winding direction (reverse rotation) based on the output signal of the encoder 30.

  In addition, when it is determined that the rotating drum 60 has rotated in the reverse direction, the applied voltage change amount calculation unit 48 determines the electromagnetic force required to keep the tension applied to the fishing line at a predetermined value based on the obtained number of rotations. A change in the applied voltage to the clutch 20 is calculated. For example, the applied voltage change calculation means 48 calculates the product of the rotation speed obtained from the rotation speed calculation means 46 and a predetermined constant corresponding to the rotation speed as a change in the applied voltage to the electromagnetic clutch 20. To be made.

  The applied voltage adjusting means 49 also applies the change in the applied voltage calculated by the applied voltage change calculating means 48 to a preset voltage setting value (or hoisting force setting value) for driving the electromagnetic clutch 20. An applied voltage obtained by adding or subtracting to a preset applied voltage is applied to the electromagnetic clutch 20.

  Next, a method for controlling the fishing machine will be described with reference to the drawings. FIG. 5 is a flowchart showing the winding drive control operation of the fishing machine 100.

  When fishing, as shown in FIG. 5, first, motor drive is started in step S1. Here, after feeding the fishing line 61 into the sea, the drive motor always rotates in the winding direction.

  Next, in step S2, the number of rotations of the rotary drum 20 is calculated. Here, the rotation speed calculation means 46 calculates the rotation speed of the rotary drum 20 based on the output signal of the encoder 30.

  Next, in step S3, it is determined whether the rotation direction of the rotary drum 20 is normal rotation or reverse rotation. Here, the rotation direction determination unit 47 determines the rotation direction of the rotary drum 20 based on the output signal of the encoder 30. If it is determined that the rotation direction of the rotary drum 20 is rotation in the winding direction (forward rotation), the process proceeds to step S4.

  In step S4, the voltage clutch 20 is controlled so as to operate at the initial setting value of the voltage applied to the electromagnetic clutch 20. Next, the process proceeds to step S7.

  On the other hand, if it is determined in step S3 that the rotation direction of the rotary drum 20 has been rotated in the lowering direction (reverse rotation), the process proceeds to step S5. In step S5, based on the number of revolutions calculated by the number of revolutions calculating means 46, a change in the applied voltage to the electromagnetic clutch 20 required to keep the tension applied to the fishing line 61 at a predetermined value is calculated. For example, the change in applied voltage = rotation speed × constant (Y). Here, the constant (Y) is a predetermined constant (for example, a constant indicating a ratio) corresponding to the rotation speed, which is determined in advance.

  Next, in step S6, the applied voltage obtained by adding or subtracting the applied voltage change calculated by the applied voltage change calculating means 48 to the preset applied voltage setting value for driving the electromagnetic clutch 20 is set to the electromagnetic clutch 20. Apply to. For example, applied voltage to the electromagnetic clutch 20 = applied voltage set value +/− applied voltage change. Thereby, the feeding amount of the fishing line 61 can be suppressed, and the formation of the deflection of the fishing line 61 can be avoided.

  In step S7, it is determined whether or not the winding drive is to be terminated. If it is determined that the winding drive is to be terminated, the control operation is terminated. On the other hand, when it is determined not to end the winding drive, the process returns to step S2 and the above-described operation is repeated.

  In step S3, when it is determined that the rotation direction of the rotary drum 20 is normal rotation, when the tension applied to the fishing line 61 changes due to, for example, the caught fish suddenly approaching the ship, the reverse rotation described above is performed. Similarly to the case, the voltage applied to the electromagnetic clutch 20 may be adjusted and controlled.

  Thus, in the present embodiment, the fishing machine 100 includes the drive motor 10, the electromagnetic clutch 20, the encoder 30, the control unit 40, the drum mounting shaft 50, and the rotating drum 60 that are disposed in the main body case 1. The control unit 40 includes an input unit 41, a display unit 42, a CPU 43, a ROM 44, a RAM 45, a rotation number calculation unit 46, a rotation direction determination unit 47, and an applied voltage change calculation unit 48. And an applied voltage adjusting means 49. When fishing, the number of rotations of the rotating drum 60 is calculated from the output signal of the encoder 30, and further the direction of rotation of the rotating drum 60 is determined, and it is determined that the rotating drum 60 has been rotated in the lowering direction (reverse rotation). If so, based on the calculated number of revolutions, a change in the applied voltage to the electromagnetic clutch 20 required to keep the tension applied to the fishing line 61 at a predetermined value is calculated, and the calculated applied voltage is changed. An application voltage obtained by adding or subtracting the minute to a preset application voltage is applied to the electromagnetic clutch 20 to control the tension applied to the fishing line 61 at a predetermined value.

  As a result, when the rotating drum rotates in the reverse direction in the lowering direction, for example, when the fishing line is pulled by a fish during fishing, the applied voltage to the electromagnetic clutch is automatically controlled to require the amount of fishing line feed. It is possible to prevent the above-mentioned feeding. Therefore, it is possible to eliminate the risk that the fish will escape due to the break of the fishing line.

  Further, since a method of detecting the rotation direction of the rotary drum from the output signal of the rotation detector is used, a simple configuration can be achieved and the cost can be reduced.

  In the above-described embodiment, an applied voltage obtained by automatically adding or subtracting a change in the applied voltage to a preset applied voltage is applied to the electromagnetic clutch 20 to keep the tension applied to the fishing line 61 at a predetermined value. Although what was controlled was demonstrated, it is not limited to this. For example, the calculated change in the applied voltage may be displayed on the display unit 42, and based on this, the applied voltage to the electromagnetic clutch 20 may be manually increased or decreased for adjustment.

  In the above-described embodiment, the method of calculating the applied voltage change to the electromagnetic clutch 20 by the applied voltage change calculation means 48 based on the rotation speed and controlling the electromagnetic clutch 20 has been described. However, the present invention is not limited to this. Is not to be done. For example, the tension of the fishing line is measured, and the applied voltage change amount calculating means 48 calculates the applied voltage change amount to the electromagnetic clutch 20 based on the obtained tension to control the electromagnetic clutch 20. .
