Description

Double bearing reel

The present invention relates to a fishing reel, and more particularly to a dual-bearing reel that discharges a fishing line forward.

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

In a conventional resistance mechanism, an electric motor that is rotatable in a two-way direction is configured to be directly coupled to the spool via a reducer. Therefore, by the handle, when the hand that rotates the reel in the winding direction is scrolled, the output shaft of the electric motor rotates in the forward rotation direction. When the output shaft of the electric motor rotates, regenerative braking is generated to apply the braking force to the handle, and the handle does not easily rotate smoothly when the hand is scrolled.

An object of the present invention is that even if resistance is generated by an electric motor, the handle can be smoothly wound when the reel is operated by hand scrolling.

The double-bearing reel of the present invention is a reel that discharges the fishing line toward the front. The double-bearing reel includes a reel body, a handle, a reel, a reel shaft, a resistance mechanism, a first rotation transmission mechanism, a resistance setting member, and a resistance control unit. The handle is a winding handle provided on the side of the reel body. The reel can be rotated for the reel body. The spool shaft rotates the spool by the rotation of the handle. The resistance mechanism has an electric motor for braking the rotation of the reel in the pay-off direction. The first rotation transmission mechanism has a planetary gear mechanism for transmitting rotation between the electric motor and the spool shaft and the spool. The resistance setting member is movably disposed on the reel body for setting the resistance of the operation resistance mechanism. The resistance control unit controls the electric motor in response to the movement position of the resistance setting member.

In the two-bearing reel, the first rotation transmission mechanism includes a planetary gear mechanism for transmitting rotation between the electric motor and the spool shaft and the spool. The planetary gear mechanism transmits rotation when any one of the sun gear, the carrier, and the ring gear is restricted, and if it is not limited, it does not transmit rotation and idling. Here, in the case where the handle is operated to rotate the spool, 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 side via the planetary gear mechanism. Thereby, it is achieved that the electric motor is not rotated when the hand is rolled, and the handle can be smoothly rotated when the reel is operated by the hand.

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

The electric motor has a hollow shaft that allows the spool shaft to pass through. The spool shaft is rotatably supported by the cord reel body, and the spool is rotatably supported by the spool shaft. In this case, since the spool shaft can be disposed to penetrate the hollow shaft, even if the electric motor and the spool are arranged side by side in the axial direction, the length of the double-bearing reel in the axial direction can be suppressed from increasing.

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

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

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

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

The resistance control unit controls the electric motor in a second drive braking mode in which the electric motor performs torque control in order to drive the spool in the payout direction. In this case, since the reel is driven in the payout direction by the electric motor, it is possible to obtain a weaker resistance than the first drive braking mode in the drive braking mode.

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

In the resistance control unit, when the resistance set by the resistance setting member is equal to or lower than the second resistance, the electric motor is controlled in the second drive braking mode. In this case, because the reel is facing the line by the electric motor Since the driving is performed, 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 the rotation of the handle to the spool shaft, and a reverse prohibition mechanism that prohibits rotation of the spool shaft in the pay-off 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.

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

<Control Department>

As shown in Fig. 5, the control unit 11 includes a first control unit 11a and a second control unit 11b. 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 unit 11a is housed in the display unit 9, and controls the electric motor 3a in accordance with the movement position (swing position) of the setting member 10. The second control unit 11b is provided in the first side casing 13 and outputs a signal corresponding to the movement position (swing position) of the setting member 10 to the first control unit 11a via the second wireless communication unit 57.

The reel sensor 58 detects the magnetic field of the detecting magnet 58a, and detects the rotational speed, the number of rotations, and the rotational direction of the reel 2. When the reel direction is detected by the reel sensor 58, the first control unit 11a can detect the rotation of the reel 2 in the payout direction. The first wireless communication unit 55 is provided to communicate the first control unit 11a and the second control unit 11b by a small-sized wireless communication standard. The phase sensor 56 and the 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 by a small-sized wireless communication standard.

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

Next, an example of the setting process of the braking mode performed by the first control unit 11a will be described based on the flowchart shown in FIG. 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 11a reads the set resistance SD of the setting member 10 from the detected value of the phase sensor 56 emitted from the second control unit 11b. In step S2, the first control unit 11a displays the read setting resistance SD on the liquid crystal display 9a of the display unit 9. In step S3, the first control unit 11a determines whether or not the read set resistance SD exceeds the first resistance D1 (for example, 200 N). The set resistance SD read is When the first resistance D1 is equal to or less than the first resistance D1, the first control unit 11a advances the processing from step S3 to step S4. In step S4, the first control unit 11a determines whether or not the read set resistance SD exceeds the second resistance D2 (for example, 100 N) 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 processing from step S4 to step S5. In step S5, the first control unit 11a determines whether or not the set resistance SD exceeds "0", that is, whether or not the setting member 10 is at the brake release position.

When it is judged that the set resistance SD is larger than the first resistance D1, the first control unit 11a advances the processing from step S3 to step S6. In step S6, the first control unit 11a sets the braking mode to the regenerative braking mode in which the braking force is large. 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 equal to or lower than the first resistance D1, the first control unit 11a advances the processing 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 of the electric motor 3a so as to drive the spool 2 in the winding direction with a duty ratio corresponding to the set resistance SD. That is, when the electric motor 3a is driven in the winding direction, the current flowing to the electric motor 3a is controlled by the duty ratio corresponding to the set resistance SD.

When it is judged that the set resistance SD is equal to or lower than the second resistance D2 When "0" is passed, the first control unit 11a advances the processing from step S5 to step S8. In step S8, the first control unit 11a sets the braking mode to the second drive 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 of the electric motor 3a so that the reel 2 is driven in the payout direction with a duty ratio corresponding to the set resistance SD. That is, when the electric motor 3a is driven in the payout direction, the current flowing to the electric motor 3a is controlled by the duty ratio corresponding to the set resistance SD. Here, since the spool 2 is braked in a braking mode in which the strength is weak in three stages, the resistance mechanism 3 can be controlled with high precision in accordance with the set resistance.

<Control action when 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, the fishing line is discharged from the reel 2 by the traveling of the fishing boat when the fishing line is released. When the fishing line is released to a certain extent, the setting member 10 is operated to set the desired resistance. The value of the set resistance SD is displayed on the liquid crystal display 9a.

When the fishing group has caught and the handle 6 is rotated in the winding direction of the clockwise direction in the first drawing, 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 a higher speed via the first rotation transmitting mechanism 5. Specifically, when the handle 6 is rotated in the winding direction in the clockwise direction of the first drawing, the spool shaft 4 is rotated in the counterclockwise direction of the first drawing. 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 at a higher speed in the counterclockwise direction via the second planetary gears 35. 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 causes the spool 2 to be oriented in the same direction as the spool shaft 4 (the first figure is counterclockwise) The winding direction is increasing in speed. At this time, the first sun gear 30 fixes the hollow shaft 21 of the electric motor 3a by controlling the electric motor 3a, and the torque of the handle 6 does not flow back to the electric motor 3a side via the first rotation transmission mechanism 5. Therefore, the hollow shaft 21 that is coupled to the first sun gear 30 so as to rotate integrally does not rotate. Therefore, the braking force of the electric motor 3a does not occur when the hand is rolled. As a result, when the hand 6 is rotated by the hand that rotates the reel 2 in the winding direction, 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 spool 2 is rotated in the pay-off direction (clockwise direction of FIG. 1). When the reel 2 is rotated in the payout direction, the second carrier 36 coupled to the spool shaft 4 causes the reverse prohibition mechanism 8 to act via the spool shaft 4, so that the rotation of the first figure in the clockwise direction is prohibited. Therefore, the second sun gear 34 is rotated at a higher speed in the counterclockwise direction of the first drawing. By this rotation, the first carrier 32 rotates in the same direction at the same speed, and the first sun gear 30 is rotated in the same direction (the first clock counterclockwise direction). When the first sun gear 30 rotates in the counterclockwise direction, the magnet 22 rotates in the same direction, and the rotation of the spool 2 in the payout direction is braked by the regenerative braking force set by the setting member 10.

In the first drive braking mode, when the pulling force of the catch is greater than the set resistance SD, the reel 2 is oriented in the payout direction (the clockwise side of Fig. 1) Rotate to). When the rotation is detected by the output of the reel sensor 58, the first control unit 11a performs torque control in accordance with the set resistance SD so that the reel 2 is driven in the winding direction. The torque is corrected in response to the winding diameter at this time. Thereby, a stronger resistance than the second drive braking mode can be obtained.

In the second drive braking mode, when the pulling force of the catch is greater than the set resistance SD, the spool 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 11a performs torque control in accordance with the set resistance SD so that the reel 2 is driven in the payout direction. The torque is corrected in response to the winding diameter at this time.

Here, since the reel 2 is braked by using the electric motor 3a, the resistance mechanism 3 of a simple structure can be obtained. Further, the electric motor 3a and the reel 2 are arranged side by side in the axial direction, and the electric motor 3a is provided with a hollow shaft 21, and the reel shaft 4 is disposed through the hollow shaft 21. With this configuration, the increase in the length in the spool axial direction of the double-bearing reel 100 using the electric motor 3a having the magnet 22 and the coil 23 can be suppressed, and the diameter of the bobbin body 2a of the spool 2 can be reduced. Further, since the electric motor 3a is rotated by the first rotation transmitting mechanism 5 to increase the rotation of the spool 2, when the resistance acts, the rotation speed of the electric motor 3a can be made faster than the rotation speed of the spool 2. As a result, it is easy to control the electric motor 3a, and it is possible to increase the resistance and make it smoother.

<Features>

The above embodiment can be expressed as follows.

(A) The double-bearing reel 100 is a reel that discharges the fishing line toward the front. The double-bearing reel 100 includes a reel body 1, a handle 6, a spool 2, a spool shaft 4, a resistance mechanism 3, a first rotation transmission mechanism 5, a setting member 10, and a first control portion 11a. The handle 6 is a winding handle provided on the side of the reel body 1. The spool 2 is rotatable to the cord reel body 1. The spool shaft 4 rotates the spool 2 by the rotation of the handle 6. The resistance mechanism 3 has an electric motor 3a for braking the rotation of the spool 2 in the payout direction. 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 spool 2. The setting member 10 is movably provided to the reel body 1 for setting the resistance of the operation resistance mechanism 3. The first control unit 11a controls the electric motor 3a in accordance with the movement position of the setting member 10.

In the dual-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 spool 2. When the first sun gear 30, the first carrier 32, and the ring gear 33 are restricted, the first planetary gear mechanism 28 transmits rotation, and if it is not limited, it does not transmit rotation and idling. Here, when the operating handle 6 rotates the spool 2 via the spool shaft 4, by controlling the electric motor 3a so that the hollow shaft 21 of the electric motor 3a does not reverse, the torque of the grip 6 does not pass through the first The rotation transmitting mechanism 5 flows back to the electric motor 3a side. Thereby, it can be achieved that when the hand is rolled, the electric motor 3a is not rotated. When the reel 2 is scrolled, 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 transmission mechanism 5 can be easily disposed between the reel 2 and the electric motor 3a.

(C) The electric motor 3a has a hollow shaft 21 through which the spool shaft 4 can be inserted. The spool shaft 4 is rotatably supported by the cord reel body 1, and the spool 2 is rotatably supported by the spool shaft 4. In this case, since the spool shaft 4 can be disposed 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, the length of the double-bearing reel 100 in the axial direction can be suppressed from increasing.

(D) The first control unit 11a controls the electric motor 3a in the regenerative braking mode in which the electric motor 3a regeneratively brakes. In this case, a 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 performs torque control in order to drive the spool 2. In this case, by performing the torque control of the electric motor 3a, it is possible to obtain a resistance that is weaker than the resistance obtained by the regenerative braking.

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

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

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

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

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

(K) When the set resistance SD set by the setting member 10 is equal to or lower than the second resistance, the first control unit 11a controls the electric motor 3a in the second drive braking mode. In this case, since the reel 2 is driven in the payout direction by the electric motor 3a, the setting member 10 can set a weaker resistance than the first drive braking mode.

(L) Double bearing reel 100, further equipped with: The rotation of the handle 6 is transmitted to the second rotation transmission mechanism 7 of the spool shaft 4 and the reverse prohibition mechanism 8 that prohibits the rotation of the spool shaft 4 in the payout direction. In this case, the rotation of the handle 6 can be transmitted to the spool 2.

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