[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric fishing reel which improves the winding performance of a fishing line by a spool drive motor and protects the spool drive motor.

[0002]

2. Description of the Related Art Conventionally, an electric fishing reel has a structure in which winding power of a spool drive motor (hereinafter referred to as "spool motor") mounted on a reel body is transmitted to a spool via a speed reduction mechanism.

FIGS. 3 and 4 show an electric fishing reel disclosed in Japanese Utility Model Laid-Open Publication No. 4-47967. In this electric fishing reel, a spool motor b for driving a spool a is connected to a front side of the spool a. frame c, as well as arranged between d, wearing the power transmission mechanism f including three gears f ₁ ~f ₃ on one of the side frame in c, the take-up spool motors b in the power transmission mechanism f The power is transmitted to the spool shaft g, and the rotation of the spool shaft g is transmitted to the spool b by the speed reduction mechanism h provided on the other side frame d side to rotate it.

[0004]

Conventionally, in the case of using this type of electric fishing reel, a spool motor is normally connected to a 12V battery to drive the spool motor and to prevent the spool motor from burning out. The current value flowing through the spool motor is detected and the current value is set to a maximum allowable value (for example, 10
When A) is exceeded, duty control of the current conduction time ratio is performed to protect the spool motor.

[0005] However, since the voltage of the battery usually decreases with use, the conventional motor-only control does not provide the desired motor output with the decrease in voltage, and the spool motor winds the fishing line. It has been pointed out that the performance is degraded.

That is, for example, when the spool motor is 120 W
In the case of withstanding use up to [12 (V) × 10 (A)], control using only the current value as described above requires 12
When the voltage of the V battery drops to about 10.5 V, the maximum rated value of the spool motor becomes 105 W with respect to 120 W.
Since the limit is set at [10.5 (V) × 10 (A)], the spool motor is not used at the maximum rated value of 120 W, and a desired motor output cannot be obtained.

On the other hand, the voltage of such a 12V battery rises to about 13.5 to 14V when fully charged, and when fishing on a shared ship or the like, the battery mounted on the ship is usually used. The electric reel for fishing is used by connecting to a battery. However, the voltage of the battery provided in the boat fluctuates depending on the condition of the engine, and a 12V battery may rise to about 14V to 17V.

Accordingly, in such a case, in the conventional control using only the current value, the maximum rated value 12
Excessive load exceeding 0 W [for example, 14 (V) × 10
(A) = 140 (W)] is applied to the spool motor, and there is a disadvantage that the spool motor cannot be sufficiently protected.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide an electric fishing reel which improves the winding performance of a fishing line by a spool motor and protects the spool motor. And

FIG. 2 is a block diagram of the spool motor control means. In FIG.
And 59 and 61 indicate an ammeter and a voltmeter for measuring the current value and the voltage value of the spool motor 17, respectively. These measured values are the product of the CPU 65 in the control means 63 incorporated in the control unit 45. The product is input to the calculation unit 67, and the product of both measured values is calculated by the product calculation unit 67, and the calculation result is input to the duty control unit 69.

Assuming that the spool motor 17 has the maximum rated value of 120 W, the maximum rated value 120 W of the spool motor 17 is stored in the storage unit 71 of the control means 63 in advance. Based on the maximum rating value stored in the spool motor 71, the spool motor 1 is controlled so that the calculation result of the product calculation section 67 matches the maximum rating value.
7, the duty ratio of the current supply time ratio is controlled .

That is, as described above, the product calculating section 67 calculates the product from the measured values of the ammeter 59 and the voltmeter 61.
When it has risen to the maximum value, the duty control unit 69, which has input the calculation result, sets the current energization time ratio of the spool motor 17 so that the product of the voltage value and the current value matches the maximum rated value 120W stored in the storage unit 67. Is duty controlled to obtain 120 (W) ÷ 14 (V) ≒ 8.57 (A)...
A command is sent to the motor drive circuit 73 so that the spool motor 17 is driven by the current value of.

On the other hand, when the voltage of the battery 57 decreases to, for example, about 10.5 V with use, the product calculating section 67
Input to the duty control unit 69, the product of the voltage value and the current value is stored in the storage unit 67 as the maximum rated value 1
The duty ratio of the current supply time ratio of the spool motor 17 is controlled so as to coincide with 20 W, and the spool motor 17 has a current value of 120 (W) ÷ 10.5 (V) ≒ 11.43 (A). A command is sent to the motor drive circuit 73 so that the motor is driven.

Since the electric fishing reel according to the present embodiment is constructed as described above, in order to carry out fishing with such an electric fishing reel, as in the conventional case, first, the clutch lever 35 is used.
Is operated to turn off the clutch.

When the clutch is turned off, the spool 9 is in the spool free state. Therefore, the fishing line 11 is paid out from the spool 9 by the weight of the tackle or the like, and the rotation of the spool 9 is adjusted by the encoder 43 to the length of the fishing line 11 drawn out. The pulse is converted into a corresponding pulse, input to the control mechanism of the yarn length measuring device, calculated, and the fed yarn length based on the calculation result is displayed on the digital display unit 49.

Accordingly, if the angler returns the clutch lever 35 to the clutch ON position at a predetermined water depth while watching the display, the clutch is turned ON and the spool 9 is wound. Wait for the fish to hit in this state. Then, when a fish hits, the drive switch 55 of the spool motor 17 may be operated or the manual handle 25 may be wound.

When the drive switch 55 is operated, the spool motor 17 is driven and its winding power is transmitted to the spool 9 via the speed reduction mechanism 23. Is wound on the spool 9. Then, to stop winding, the operation of the drive switch 55 may be stopped.

On the other hand, if the manual handle 25 is operated when a fish hits, the winding power is reduced by the speed reduction mechanism 23.
The fishing line 11 is transmitted to the spool 9 by the
Will be wound up. Then, to stop the winding, the winding operation of the manual handle 25 may be stopped.

When the spool motor 17 is driven by operating the drive switch 55 as described above, the product calculating section 67
Calculates the product from the measured values of the ammeter 59 and the voltmeter 61. If the voltage of the battery 57 has risen to 14 V due to full charge, the duty control unit 6
9, the spool motor 1 is controlled so that the product of the voltage value and the current value matches the maximum rated value 120 W stored in the storage unit 67.
7 is duty-controlled, and a command is sent to the motor drive circuit 73 to drive the spool motor 17 with a current value of 8.57 A from the above equation, so that the spool motor 17 has a maximum rated value of 120 W Drive with

On the other hand, the voltage of the battery 57
When the voltage drops to about 0.5 V, the duty control unit 69, which has input the calculation result of the product calculation unit 67, stores the product of the voltage value and the current value in the maximum rated value 120W stored in the storage unit 67.
The duty ratio of the current supply time ratio of the spool motor 17 is controlled so as to coincide with the above, and a command is sent to the motor drive circuit 73 to drive the spool motor 17 with the current value of 11.43 A from the above equation. The spool motor 17 is driven at the maximum rated value of 120 W.

As described above, according to the present embodiment, when the voltage of the spool motor 17 increases, the current value of the spool motor 17 is reduced by duty control of the current energization time ratio.
When the voltage value of the spool motor 17 decreases,
By increasing the current value by duty-controlling the current conduction time ratio, the spool motor 17 always maintains the maximum rated value 120
It is driven by W.

Therefore, according to the present embodiment, even if the voltage value of the spool motor 17 rises, an excessive load is not applied to the spool motor 17 as in the prior art. It was decided to be.

In this embodiment, even if the voltage value of the spool motor 17 drops, the spool motor 17 can always be driven at the maximum rated value of 120 W, so that a desired motor output can be obtained. Thus, the winding performance of the fishing line by the spool motor 17 is improved as compared with the related art.

In the above embodiment, the present invention is applied to a so-called manual and automatic electric fishing reel. However, it goes without saying that the present invention can be applied to an electric fishing reel having no manual handle 25. However, the spool motor 17 does not necessarily need to be built in the spool motor 17,
As in the conventional case, the spool may be mounted between the side frames 5 and 7 in front of the spool 9.

[0036]

As described above, in the electric fishing reel according to the present invention, when the voltage value of the spool motor rises, the duty ratio of the current supply time of the spool motor is controlled.
When the voltage value of the spool motor decreases, the current conduction time rate of the spool motor decreases.
Since the spool motor is always driven at the maximum rated value by increasing the current value by duty control ,
According to the present invention, an excessive load is not applied to the spool motor even if the voltage value increases as compared with the conventional electric fishing reel, and a desired motor output can be obtained even if the voltage decreases. Therefore, the winding performance of the fishing line by the spool motor is improved.
