Description

Double bearing coiler

The present invention relates to a fishing reel, and more particularly to a double-bearing reel for releasing a fishing line forward.

The double-bearing reel is provided with a mechanism called a resistance mechanism, that is, a mechanism for controlling the rotation of the spool in the pay-off direction. As a conventional two-bearing reel having a resistance mechanism, a two-bearing reel using an electric motor to brake a reel is known (for example, refer to Patent Document 1). In the conventional double-bearing reel, a resistance mechanism is constituted by an electric motor having a reduction gear. The output shaft of this electric motor is directly connected to the drum via a speed reducer. In the conventional resistance mechanism using an electric motor, the electric motor is used as a generator. The regenerative braking that consumes the electromotive force generated by the rotation of the reel in the pay-off direction with a variable resistor allows the electric motor to brake the reel.

In the conventional resistance mechanism, an electric motor capable of rotating in both directions is arranged to be directly connected to the drum via a speed reducer. Therefore, with the handle, when the hand is rotated by rotating the reel in the winding direction, the output shaft of the electric motor rotates at a higher speed in the forward direction. When the output shaft of the electric motor rotates, regenerative braking is generated to allow the braking force to act on the handle, and it is difficult to turn the handle smoothly when it is operated by hand.

An object of the present invention is to smoothly wind a handle when a reel is operated by hand even if resistance is generated by an electric motor.

The double bearing reel according to the present invention is a reel that releases a fishing line forward. The double bearing reel includes a reel main body, a handle, a reel, a reel shaft, a resistance mechanism, a first rotation transmitting mechanism, a resistance setting member, and a resistance control unit. The handle is a handle for winding a wire provided on the side of the main body of the winder. The reel is rotatable with respect to the main body of the reel. The reel shaft rotates the reel by rotating the handle. The resistance mechanism includes an electric motor for braking rotation of the reel in the pay-off direction. The first rotation transmission mechanism includes a planetary gear mechanism for transmitting rotation between the electric motor, the spool shaft, and the spool. The resistance setting member is movably disposed on the main body of the reel, and is used to set the resistance for operating the resistance mechanism. The resistance control unit controls the electric motor in accordance with the moving position of the resistance setting member.

In this double-bearing winder, the first rotation transmission mechanism includes a planetary gear mechanism for transmitting rotation between the electric motor, the spool shaft, and the spool. In the planetary gear mechanism, if any of the sun gear, the carrier, and the ring gear is restricted, the rotation is transmitted, and if it is not restricted, the rotation is not transmitted and the engine is idling. Here, when the reel is rotated by operating the handle, by controlling the electric motor so that the shaft of the electric motor does not reverse, the torque of the handle does not flow back to the electric motor through the planetary gear mechanism. In this way, it can be achieved that the electric motor does not rotate when scrolled by hand, and the handle can be smoothly rotated when the reel is operated by scroll.

The electric motor is arranged side by side with the reel in the direction of the reel axis. In this case, the first rotation transmitting mechanism can be easily disposed between the reel and the electric motor.

The electric motor has a hollow shaft through which a spool shaft can pass. The reel shaft is rotatably supported by the reel body, and the reel is rotatably supported by the reel shaft. In this case, since the reel shaft can be arranged to penetrate the hollow shaft, even if the electric motor and the reel are arranged side by side in the axial direction, it is possible to suppress an increase in the length of the double bearing reel in the axial direction.

The resistance control unit controls the electric motor in a regenerative braking mode of the electric motor regenerative braking. In this case, strong resistance can be obtained by regenerative braking.

In order to drive the reel, the resistance control unit controls the electric motor in a drive braking mode in which the electric motor is torque-controlled. In this case, by performing torque control of the electric motor, a resistance that is weaker than that obtained by regenerative braking can be obtained.

When the resistance set by the resistance setting means exceeds the first resistance, the resistance control section controls the electric motor in a regenerative braking mode. In this case, a strong resistance can be set by the resistance setting member.

When the resistance set by the resistance setting member is equal to or lower than the first resistance, the resistance control unit controls the electric motor in a drive braking mode. In this case, the resistance setting member can set a resistance that is weaker than the regenerative braking force, and can set the resistance in a wide range.

In order to drive the reel in the winding direction, the resistance control unit controls the electric motor in a first drive braking mode in which the electric motor is torque-controlled. In this case, since the spool is driven in the winding direction by the electric motor, a strong resistance can be obtained in the drive braking mode.

In order to drive the spool in the pay-off direction, the resistance control unit controls the electric motor in a second drive braking mode in which the electric motor is torque-controlled. In this case, since the spool is driven in the pay-off direction by the electric motor, a weaker resistance can be obtained in the driving braking mode than in the first driving braking mode.

The resistance control unit controls the electric motor in the first driving braking mode when the resistance set by the resistance setting member is equal to or lower than the first resistance and exceeds a second resistance smaller than the first resistance. In this case, the resistance between the resistance in the regenerative braking mode and the resistance in the second drive control mode can be set by the resistance setting means.

When the resistance set by the resistance setting means is equal to or lower than the second resistance, the resistance control unit controls the electric motor in the second drive braking mode. In this case, since the reel is oriented toward the pay-off side by the electric motor Directional driving, so the resistance setting member can set a weaker resistance than the first driving braking mode.

The double-bearing reel further includes a second rotation transmission mechanism that transmits rotation of the handle to the spool shaft, and a reverse prohibition mechanism that prohibits rotation of the spool shaft in the release direction. In this case, the rotation of the handle can be transmitted to the reel.

The electric motor is a brushless motor. In this case, the drum can be braked by a brushless motor that is easy to maintain.

With the present invention, even if resistance is generated by the electric motor, when the reel is operated by hand, the handle can be smoothly wound.

<Control section>

As shown in FIG. 5, the control unit 11 includes a first control unit 11 a and a second control unit 11 b. The first control unit 11a and the second control unit 11b are configured by, for example, a microcomputer. The first control unit 11a is an example of a resistance control unit. The first control section 11 a is housed in the display section 9 and controls the electric motor 3 a in accordance with the movement position (swing position) of the setting member 10. The second control unit 11 b is provided in the first side housing 13 and outputs a signal corresponding to the moving position (swing position) of the setting member 10 to the first control unit 11 a via the second wireless communication unit 57.

As shown in FIG. 5, the first control unit 11 a is electrically connected. There are an operation button 54, a rotation position sensor 24, a reel sensor 58, a liquid crystal display 9a, an electric motor 3a, a first wireless communication section 55, and a memory section 60. The reel sensor 58 can detect the magnetic field of the detection magnet 58 a to detect the rotation speed, the number of rotations, and the rotation direction of the reel 2. When the reel sensor 58 detects the rotation direction, the first control unit 11 a can detect the rotation in the pay-off direction of the reel 2. The first wireless communication unit 55 is provided so that the first control unit 11a and the second control unit 11b can communicate with each other by a small-sized wireless communication standard. A phase sensor 56 and a second wireless communication unit 57 are electrically connected to the second control unit 11b. The second wireless communication unit 57 can communicate with the first wireless communication unit 55 using a small-sized wireless communication standard.

The first control unit 11a can control the electric motor 3a in three braking modes of the regenerative braking mode, the first driving braking mode, and the second driving braking mode in accordance with the operation position of the member 10.

Next, an example of the braking mode setting process performed by the first control unit 11a will be described with reference to a flowchart shown in FIG. 6. FIG. 6 is an example of a control operation, and the present invention is not limited to the control operation shown in FIG. 6.

In step S1 of FIG. 6, the first control unit 11 a reads the setting resistance SD of the setting member 10 from the detection value of the phase sensor 56 issued by the second control unit 11 b. In step S2, the first control unit 11a displays the read set resistance SD on the liquid crystal display 9a of the display unit 9. In step S3, the first control unit 11a determines whether the read set resistance SD exceeds the first resistance D1 (for example, 200 N). The read resistance SD is In the case of the first resistance D1 or less, the first control unit 11a advances the process from step S3 to step S4. In step S4, the first control unit 11a determines whether or not the read set resistance SD exceeds a second resistance D2 (for example, 100N) smaller than the first resistance D1. When the set resistance SD is equal to or lower than the second resistance D2, the first control unit 11a advances the process from step S4 to step S5. In step S5, the first control unit 11a determines whether the set resistance SD exceeds "0", that is, determines whether the setting member 10 is at the brake release position.

When it is determined that the set resistance SD is greater than the first resistance D1, the first control unit 11a advances the process from step S3 to step S6. In step S6, the first control unit 11a sets the braking mode to a regenerative braking mode with a large braking force. In the regenerative braking mode, the first control unit 11a controls the current generated from the electric motor 3a with a duty ratio corresponding to the set resistance SD.

When it is determined that the set resistance SD exceeds the second resistance D2 and is below the first resistance D1, the first control unit 11a advances the process from step S4 to step S7. In step S7, the first control unit 11a sets the braking mode to the first driving braking mode in which the braking force is smaller than the regenerative braking mode. In the first drive braking mode, the first control unit 11a performs torque control on the electric motor 3a so as to drive the spool 2 in the winding direction with a duty ratio according to the set resistance SD. That is, when the electric motor 3a is driven in the winding direction, the current flowing in the electric motor 3a is controlled with a duty ratio corresponding to the set resistance SD.

When it is judged that the set resistance SD is below the second resistance D2 and exceeds When "0" is passed, the first control unit 11a advances the process from step S5 to step S8. In step S8, the first control unit 11a sets the braking mode to the second driving braking mode in which the braking force is smaller than the first driving braking mode. In the second drive braking mode, the first control unit 11a performs torque control on the electric motor 3a so as to drive the spool 2 in the pay-off direction at a duty ratio according to the set resistance SD. That is, when the electric motor 3a is driven in the pay-off direction, the current flowing through the electric motor 3a is controlled with a duty ratio corresponding to the set resistance SD. Here, since the reel 2 is braked in three different braking modes, the resistance mechanism 3 can be controlled with high accuracy in accordance with the set resistance.

<Control actions during fishing>

When the fishing line is released, the setting member 10 is operated to the brake release position, and the electric motor 3a does not perform regenerative braking. In this state, when the fishing line is released, the fishing line is released from the reel 2 by running the fishing boat. When the fishing line is released to a certain degree, the setting member 10 is operated to set a desired resistance. The value of the set resistance SD is displayed on the liquid crystal display 9a.

When the fishing group has caught the fish and rotates the handle 6 in the clockwise winding direction in FIG. 1, the rotation is transmitted to the spool shaft 4 via the second rotation transmitting mechanism 7. The rotation of the spool shaft 4 is transmitted to the spool 2 at an increased speed via the first rotation transmission mechanism 5. Specifically, when the handle 6 is rotated in the clockwise winding direction in FIG. 1, the reel shaft 4 is rotated in the counterclockwise direction in FIG. 1. This rotation is transmitted to the second carrier 36 by the first pin member 26, and the second carrier 36 is rotated in the counterclockwise direction. When the second carrier 36 rotates, The second sun gear 34 is rotated in the counterclockwise direction through the second planetary gear 35 at an increased speed. Thereby, the first carrier 32 that rotates integrally with the second sun gear 34 is rotated in the counterclockwise direction, and the first planetary gear 31 is used to make the reel 2 in the same direction as the reel shaft 4 (counterclockwise in FIG. 1) ) The winding direction rotates at an increased speed. At this time, the first sun gear 30 controls the electric motor 3 a to fix the hollow shaft 21 of the electric motor 3 a so that the torque of the handle 6 does not flow back to the electric motor 3 a side via the first rotation transmitting mechanism 5. Therefore, the hollow shaft 21 which is rotatably connected to the first sun gear 30 does not rotate, and therefore, the braking force of the electric motor 3a is not generated when the hollow shaft 21 is rolled by hand. As a result, when the manual scroll operation of rotating the reel 2 in the winding direction by the handle 6 is performed, the handle 6 is smoothly rotated.

In the regenerative braking mode, when the pulling force of the catch is greater than the set resistance SD, the reel 2 is rotated in the pay-off direction (clockwise direction in FIG. 1). When the reel 2 is rotated in the pay-off direction, the second carrier 36 connected to the reel shaft 4 allows the reversal prohibition mechanism 8 to act via the reel shaft 4, so the clockwise rotation of the first figure is prohibited. Therefore, the second sun gear 34 is rotated in the counterclockwise direction in FIG. 1 at an increased speed. By this rotation, the first carrier 32 is rotated at the same speed and in the same direction, and the first sun gear 30 is rotated at an increased speed in the same direction (counterclockwise direction in FIG. 1). When the first sun gear 30 rotates at an increased speed in the counterclockwise direction, the magnet 22 rotates at an increased speed in the same direction to brake the rotation of the spool 2 in the pay-off direction by the regenerative braking force set by the setting member 10.

In the first drive braking mode, when the catch pull is greater than the set resistance SD, the reel 2 is oriented in the pay-off direction (clockwise in FIG. 1). To). When the rotation is detected by the output of the reel sensor 58, the first control unit 11 a performs torque control in accordance with the set resistance SD so as to drive the reel 2 in the winding direction. Correct the torque according to the winding diameter at this time. This makes it possible to obtain a stronger resistance than in the second drive braking mode.

In the second driving braking mode, when the catch force is greater than the set resistance SD, the reel 2 is rotated in the pay-off direction (clockwise direction in FIG. 1). When the rotation is detected by the output of the reel sensor 58, the first control unit 11 a performs torque control based on the set resistance SD so as to drive the reel 2 in the pay-off direction. Correct the torque according to the winding diameter at this time.

Here, since the reel 2 is braked by using the electric motor 3a, the resistance mechanism 3 having a simple structure can be obtained. The electric motor 3 a and the reel 2 are arranged side by side in the axial direction. The electric motor 3 a is provided with a hollow shaft 21, and the reel shaft 4 is arranged through the hollow shaft 21. With this structure, an increase in the length in the spool axis direction of the double-bearing reel 100 using the electric motor 3 a having the magnet 22 and the coil 23 can be suppressed, and the diameter of the spool body 2 a of the spool 2 can be reduced. In addition, since the rotation of the reel 2 is increased by the first rotation transmission mechanism 5 and the electric motor 3a is rotated, when the resistance is applied, the rotation speed of the electric motor 3a can be made faster than the rotation speed of the reel 2. As a result, it is easy to control the electric motor 3a, and the resistance can be increased and smoothed.

<Feature>

The above embodiment can be expressed as follows.

(A) The double bearing reel 100 is a reel that releases a fishing line forward. The double-bearing reel 100 includes a reel main body 1, a handle 6, a reel 2, a reel shaft 4, a resistance mechanism 3, a first rotation transmitting mechanism 5, a setting member 10, and a first control unit 11a. The handle 6 is a winding handle provided on the side of the reel main body 1. The reel 2 is rotatable with respect to the reel main body 1. The reel shaft 4 rotates the reel 2 by rotating the handle 6. The resistance mechanism 3 includes an electric motor 3 a for braking the rotation in the pay-off direction of the spool 2. The first rotation transmission mechanism 5 includes a first planetary gear mechanism 28 for transmitting rotation between the electric motor 3 a and the spool shaft 4 and the spool 2. The setting member 10 is movably provided on the reel main body 1 and is used to set the resistance of the operation resistance mechanism 3. The first control unit 11 a controls the electric motor 3 a in accordance with the moving position of the setting member 10.

In the double-bearing reel 100, the first rotation transmission mechanism 5 includes a first planetary gear mechanism 28 for transmitting rotation between the electric motor 3a, the spool shaft 4, and the reel 2. In the first planetary gear mechanism 28, if any of the first sun gear 30, the first carrier 32, and the ring gear 33 is restricted, the rotation is transmitted, and if it is not restricted, the rotation is not transmitted and the engine is idling. Here, when the reel 2 is rotated by operating the handle 6 through the reel shaft 4, the electric motor 3a is controlled so that the hollow shaft 21 of the electric motor 3a does not reverse, and the torque of the handle 6 does not pass through the The rotation transmitting mechanism 5 flows back to the electric motor 3a. This can be achieved when the electric motor 3a is not rotated when scrolled by hand, When the reel 2 is rolled, the handle 6 can be smoothly rotated.

(B) The electric motor 3a is arranged side by side with the spool 2 in the spool axis direction. In this case, the first rotation transmitting mechanism 5 can be easily disposed between the reel 2 and the electric motor 3a.

(C) The electric motor 3a includes a hollow shaft 21 through which the spool shaft 4 can pass. The spool shaft 4 is rotatably supported by the spool main body 1, and the spool 2 is rotatably supported by the spool shaft 4. In this case, since the spool shaft 4 can be arranged to penetrate the hollow shaft 21, even if the electric motor 3a and the spool 2 are arranged side by side in the axial direction, it is possible to suppress an increase in the length of the double bearing reel 100 in the axial direction.

(D) The first control unit 11a controls the electric motor 3a in a regenerative braking mode for regenerative braking of the electric motor 3a. In this case, strong resistance can be obtained by regenerative braking.

(E) The first control unit 11a controls the electric motor 3a in a drive braking mode in which the electric motor 3a is torque-controlled in order to drive the reel 2. In this case, by performing torque control of the electric motor 3a, a resistance that is weaker than that obtained by regenerative braking can be obtained.

(F) The first control unit 11a controls the electric motor 3a in a regenerative braking mode when the set resistance SD set by the setting member 10 exceeds the first resistance D1. In this case, a strong resistance can be set by the setting member 10.

(G) The first control unit 11a controls the electric motor 3a in the drive braking mode when the set resistance SD set by the setting member 10 is equal to or less than the first resistance D1. In this case, by setting the configuration The piece 10 can set the resistance which is weaker than the regenerative braking force, and can set the resistance in a wide range.

(H) In order to drive the reel 2 in the winding direction, the first control unit 11a controls the electric motor 3a in a first drive braking mode in which the electric motor 3a is torque-controlled. In this case, since the spool 2 is driven in the winding direction by the electric motor 3a, a strong resistance can be obtained in the drive braking mode.

(I) In order to drive the spool 2 in the pay-off direction, the first control unit 11a controls the electric motor 3a in a second drive braking mode in which the electric motor 3a is torque-controlled. In this case, since the spool 2 is driven in the pay-off direction by the electric motor 3a, a weaker resistance can be obtained in the driving braking mode than in the first driving braking mode.

(J) When the first control unit 11a is set to be less than the first resistance D1 by the setting resistance SD set by the setting member 10, and exceeds the second resistance D2 which is smaller than the first resistance D1, the first control unit 11a is driven by the first drive. The braking mode controls the electric motor 3a. In this case, the resistance between the resistance in the regenerative braking mode and the resistance in the second drive control mode can be set by the setting member 10.

(K) The first control unit 11a controls the electric motor 3a in the second drive braking mode when the set resistance SD set by the setting member 10 is equal to or lower than the second resistance. In this case, since the spool 2 is driven in the pay-off direction by the electric motor 3a, the setting member 10 can set a resistance that is weaker than the first driving braking mode.

(L) The double bearing winder 100 further includes: The rotation of the handle 6 is transmitted to the second rotation transmission mechanism 7 of the reel shaft 4 and the reversal prohibition mechanism 8 for inhibiting rotation of the reel shaft 4 in the pay-off direction. In this case, the rotation of the handle 6 can be transmitted to the reel 2.

(M) The electric motor 3a is a brushless motor. In this case, the drum 2 can be braked by a brushless motor that is easy to maintain.
