Description

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

  The dual-bearing reel is provided with a mechanism called a drag mechanism that brakes the rotation of the spool in the yarn unwinding direction. In a double-bearing reel having a conventional drag mechanism, a double-bearing reel that uses an electric motor to brake a spool is known (for example, see Patent Document 1). In a conventional dual-bearing reel, a drag mechanism is configured by an electric motor having a speed reducer. The output shaft of this electric motor is directly connected to the spool via a speed reducer. In a drag mechanism using a conventional electric motor, the electric motor acts as a generator. The electric motor brakes the spool by regenerative braking that consumes the electromotive force generated by the rotation of the spool in the yarn unwinding direction by the variable resistance.

Japanese Utility Model Publication No. 50-21993

  In a conventional drag mechanism, an electric motor that can rotate in both directions is arranged directly connected to a spool via a speed reducer. For this reason, during the manual winding operation in which the spool is rotated in the yarn winding direction by the handle, the output shaft of the electric motor is increased in the forward direction and rotated. When the output shaft of the electric motor rotates, regenerative braking occurs and braking force acts on the handle, making it difficult to turn the handle smoothly during manual winding operation.

  An object of the present invention is to enable a handle to be smoothly rotated when a spool is manually wound even when a drag force is generated by an electric motor.

  The dual-bearing reel according to the present invention is a reel that feeds a fishing line forward. The dual-bearing reel includes a reel body, a handle, a spool, a spool shaft, a drag mechanism, a first rotation transmission mechanism, a drag setting member, and a drag control unit. The handle is for bobbin winding provided on the side of the reel body. The spool is rotatable with respect to the reel body. The spool shaft rotates the spool by the rotation of the handle. The drag mechanism has an electric motor that brakes the rotation of the spool in the yarn unwinding direction. The first rotation transmission mechanism includes a planetary gear mechanism that transmits rotation between the electric motor, the spool shaft, and the spool. The drag setting member is movably provided on the reel body, and is configured to perform a setting operation of the drag force of the drag mechanism. The drag control unit controls the electric motor according to the movement position of the drag setting member.

  In this dual-bearing reel, the first rotation transmission mechanism has a planetary gear mechanism that transmits rotation between the electric motor, the spool shaft, and the spool. When one of the sun gear, the carrier, and the ring gear is constrained, the planetary gear mechanism transmits the rotation. When none of the planetary gear mechanisms is constrained, the planetary gear mechanism rotates idle without transmitting the rotation. Here, when rotating the spool by operating the handle, the torque of the handle is prevented from flowing back to the electric motor side via the planetary gear mechanism by controlling the electric motor so that the shaft of the electric motor does not reverse. it can. As a result, a configuration in which the electric motor is not rotated during manual winding can be realized, and the handle can be smoothly rotated when the spool is manually wound.

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

  The electric motor may have a hollow shaft through which the spool shaft can pass. The spool shaft may be rotatably supported on the reel body, and the spool may be rotatably supported on the spool shaft. In this case, since the spool shaft can be disposed through the hollow shaft, an increase in the axial length of the dual-bearing reel can be suppressed even if the electric motor and the spool are disposed side by side in the axial direction.

  The drag control unit may control the electric motor in a regenerative braking mode in which the electric motor performs regenerative braking. In this case, a strong drag force can be obtained by regenerative braking.

  The drag control unit may control the electric motor in a drive braking mode in which the electric motor is torque controlled so as to drive the spool. In this case, it is possible to obtain a drag force that is weaker than the drag force by regenerative braking by controlling the torque of the electric motor.

  The drag control unit may control the electric motor in the regenerative braking mode when the drag force set by the drag setting member exceeds the first drag force. In this case, a strong drag force can be set by the drag setting member.

  The drag control unit may control the electric motor in the drive braking mode when the drag force set by the drag setting member is equal to or less than the first drag force. In this case, a drag force weaker than the regenerative braking force can be set by the drag setting member, and the drag force can be set in a wide range.

  The drag control unit may control the electric motor in a first drive braking mode in which the electric motor is torque-controlled so as to drive the spool in the yarn winding direction. In this case, since the spool is driven in the yarn winding direction by the electric motor, a strong drag force can be obtained in the drive braking mode.

  The drag control unit may control the electric motor in a second drive braking mode in which the electric motor is torque-controlled so as to drive the spool in the yarn feeding direction. In this case, since the spool is driven in the yarn unwinding direction by the electric motor, a drag force weaker than that in the first drive braking mode can be obtained in the drive braking mode.

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

  The drag control unit may control the electric motor in the second drive braking mode when the drag force set by the drag setting member is equal to or less than the second drag force. In this case, since the spool is driven in the yarn feeding direction by the electric motor, it is possible to set a drag force weaker than that in the first drive braking mode by the drag setting member.

  The dual-bearing reel may further include a second rotation transmission mechanism that transmits the rotation of the handle to the spool shaft, and a reverse rotation prohibiting mechanism that prohibits the rotation of the spool shaft in the thread drawing direction. In this case, the rotation of the handle can be transmitted to the spool.

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

  According to the present invention, even when the drag force is generated by the electric motor, the handle can be smoothly turned when the spool is manually wound.

The first planetary gear mechanism 28 includes a first sun gear 30, a plurality of (for example, three) first planetary gears 31, a first carrier 32, and a ring gear 33. The first sun gear 30 is coupled to the hollow shaft 21 so as to be integrally rotatable. The plurality of first planetary gears 31 mesh with the first sun gear 30.

Have The ratchet wheel 50 has the 2nd slit 50b engaged with the both ends which the 2nd pin member 27 protrudes in the center part.

  The stopper claw 52 is separated from the ratchet teeth 50a when the spool shaft 4 is rotated in the yarn winding direction by a control member (not shown). Further, when the spool shaft 4 rotates in the direction opposite to the yarn winding direction, it engages with the ratchet teeth 50a. Thereby, the rotation (reverse rotation) of the spool shaft 4 in the yarn feeding direction is prohibited. In this embodiment, two stopper claws 52 are provided in order to prohibit the reverse rotation of the ratchet wheel 50 at a rotational phase that is half the rotational phase determined by the number of ratchet teeth 50a. Therefore, the spool shaft 4 does not normally rotate in the yarn feeding direction ().

<Display section>
As shown in FIG. 1, the display unit 9 is provided to display the drag force set by the setting member 10 in units of N (Newton), for example. The display unit 9 includes a liquid crystal display 9a capable of displaying numerical values and figures. When a sensor for detecting the number of rotations from a predetermined position (for example, the bobbin trunk 2a) of the spool 2 is provided, the fishing line feeding length may be calculated and displayed. The display unit 9 is provided with at least one operation button 54. The drag force set by the setting member 10 may be finely adjusted or shifted by operating the operation button 54.

<Setting member>
As shown in FIGS. 1 and 2, the setting member 10 has the same shape as a drag lever of a normal mechanical drag mechanism. The setting member 10 is provided to set the drag force generated by the electric motor 3a in a plurality of stages (for example, a range of 10 to 40 stages). The setting member 10 is supported by the first side cover 13 so as to be swingable within a range of 120 degrees, for example, from the braking release position indicated by a two-dot chain line in FIG. The setting member 10 includes an arm portion 10a extending in the radial direction and an operation portion 10b fixed to the tip of the arm portion 10a. The base end of the arm portion 10a is connected to a detection shaft 56a of a phase sensor 56 formed of, for example, a rotary encoder for detecting the swing position of the setting member 10 so as to be integrally rotatable. The setting member 10 can be positioned in a plurality of stages by a positioning mechanism (not shown). In the setting member 10, the drag force can be set up to a maximum of 400N, for example.

<Control unit>
As shown in FIG. 5, the control unit 11 includes a first control unit 11a and a second control unit 11b. The 1st control part 11a and the 2nd control part 11b are comprised by the microcomputer, for example. The first control unit 11a is an example of a drag control unit. The first control unit 11a is housed in the display unit 9, and controls the electric motor 3a according to the movement position (swing position) of the setting member 10. The second control unit 11 b is provided on the first side cover 13 and outputs a signal corresponding to the movement 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 11a includes an operation button 54, a rotational position sensor 24, a spool sensor 58, a liquid crystal display 9a, an electric motor 3a, a first wireless communication unit 55, The storage unit 60 is electrically connected. The spool sensor 58 can detect the rotation speed, the number of rotations, and the rotation direction of the spool 2 by detecting the magnetic field of the detection magnet 58a. When the spool sensor 58 detects the rotation direction, the first control unit 11a can detect the rotation of the spool 2 in the yarn feeding direction. The first wireless communication unit 55 is provided to enable communication between the first control unit 11a and the second control unit 11b according to a small-scale 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 according to a small-scale wireless communication standard.

  The first control unit 11a controls the electric motor 3a in three braking modes including a regenerative braking mode, a first driving braking mode, and a second driving braking mode, according to the operation position of the setting member 10.

Next, an example of a braking mode setting process by the first control unit 11a will be described based on a flowchart shown in FIG. FIG. 6 is an example of control, and the present invention is not limited to the control shown in FIG.
In step S1 of FIG. 6, the first control unit 11a reads the set drag force SD of the setting member 10 from the detection value of the phase sensor 56 transmitted from the second control unit 11b. In step S <b> 2, the first control unit 11 a displays the read set drag force SD on the liquid crystal display 9 a of the display unit 9. In step S3, the first control unit 11a determines whether or not the read set drag force SD exceeds a first drag force D1 (for example, 200 N). When the read set drag force SD is equal to or less than the first drag force D1, the first control unit 11a advances the process from step S3 to step S4. In step S4, the first controller 11a determines whether or not the read set drag force SD exceeds a second drag force D2 (for example, 100 N) that is smaller than the first drag force D1. When the set drag force SD is equal to or less than the second drag force 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 or not the set drag force SD exceeds “0”, that is, determines whether or not the setting member 10 is in the brake release position.

  When determining that the set drag force SD is greater than the first drag force D1, the first controller 11a advances the process from step S3 to step S6. In step S6, the first controller 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 drag force SD.

  If it is determined that the set drag force SD exceeds the second drag force D2 and is equal to or less than the first drag force D1, the first controller 11a advances the process from step S4 to step S7. In step S7, the first controller 11a sets the braking mode to the first drive braking mode in which the braking force is smaller than the regenerative braking mode. In the first drive braking mode, the first controller 11a controls the torque of the electric motor 3a so as to drive the spool 2 in the yarn winding direction with a duty ratio corresponding to the set drag force SD. That is, when the electric motor 3a is driven in the yarn winding direction, the current flowing through the electric motor 3a is controlled with a duty ratio corresponding to the set drag force SD.

  If it is determined that the set drag force SD is equal to or less than the second drag force D2 and exceeds “0”, the first controller 11a advances the process from step S5 to step S8. In step S8, the first controller 11a sets the braking mode to the second driving braking mode in which the braking force is smaller than that of the first driving braking mode. In the second drive braking mode, the first control unit 11a controls the torque of the electric motor 3a so as to drive the spool 2 in the yarn unwinding direction with a duty ratio corresponding to the set drag force SD. That is, when the electric motor 3a is driven in the yarn unwinding direction, the current flowing through the electric motor 3a is controlled with a duty ratio corresponding to the set drag force SD. Here, since the spool 2 is braked in three different braking modes in the strength and weakness, the drag mechanism 3 can be accurately controlled according to the set drag force.

<Control action when fishing>
When feeding the fishing line, the setting member 10 is operated to the braking release position so that the electric motor 3a cannot perform regenerative braking. In this state, when the fishing line is fed out, the fishing line is fed out from the spool 2 by the traveling of the fishing boat. When the fishing line is fed out to some extent, the setting member 10 is operated to set a desired drag force. The value of the set drag force SD is displayed on the liquid crystal display 9a.

  When a prey is applied to the device and the handle 6 is rotated in the direction of winding the thread clockwise in FIG. 1, the rotation is transmitted to the spool shaft 4 via the second rotation transmission 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 rotates in the clockwise direction for winding the thread in FIG. 1, the spool shaft 4 rotates counterclockwise in FIG. This rotation is transmitted to the second carrier 36 by the first pin member 26, and the second carrier 36 rotates counterclockwise. When the second carrier 36 rotates, the second sun gear 34 rotates in the counterclockwise direction through the second planetary gear 35. As a result, the first carrier 32 that rotates integrally with the second sun gear 34 rotates counterclockwise, and the first planetary gear 31 causes the spool 2 to wind up the thread in the same direction as the spool shaft 4 (counterclockwise in FIG. 1). Rotate at an increased speed in the direction. 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 is transferred to the electric motor 3 a side via the first rotation transmission mechanism 5. It can be configured not to flow backward. For this reason, since the hollow shaft 21 connected to the first sun gear 30 so as to be integrally rotatable does not rotate, no braking force is generated by the electric motor 3a during manual winding. As a result, the handle 6 can be smoothly rotated when the handle 6 is manually wound to rotate the spool 2 in the yarn winding direction.

  In the regenerative braking mode, when the force with which the prey is pulled becomes greater than the set drag force SD, the spool 2 rotates in the yarn feeding direction (clockwise in FIG. 1). When the spool 2 rotates in the yarn pay-out direction, the second carrier 36 connected to the spool shaft 4 is prohibited from rotating clockwise in FIG. 1 because the reverse rotation prohibiting mechanism 8 acts via the spool shaft 4. For this reason, the second sun gear 34 rotates at an increased speed counterclockwise in FIG. By this rotation, the first carrier 32 rotates in the same direction at the same speed, and the first sun gear 30 rotates at an increased speed in the same direction (counterclockwise in FIG. 1). When the first sun gear 30 rotates counterclockwise, the magnet 22 rotates in the same direction, and the regenerative braking force set by the setting member 10 brakes the rotation of the spool 2 in the yarn unwinding direction. .

  In the first drive braking mode, when the force with which the prey is pulled becomes greater than the set drag force SD, the spool 2 rotates in the yarn unwinding direction (clockwise in FIG. 1). When this rotation is detected by the output of the spool sensor 58, the first controller 11a controls the torque of the electric motor 3a according to the set drag force SD so as to drive the spool 2 in the yarn winding direction. At this time, the torque is corrected according to the bobbin diameter. Thereby, a drag force stronger than that in the second drive braking mode can be obtained.

  In the second drive braking mode, when the force with which the prey is pulled becomes larger than the set drag force SD, the spool 2 rotates in the yarn feeding direction (clockwise in FIG. 1). When this rotation is detected by the output of the spool sensor 58, the first control unit 11a controls the torque of the electric motor 3a according to the set drag force SD so as to drive the spool 2 in the yarn feeding direction. At this time, the torque is corrected according to the bobbin diameter.

  Here, since the spool 2 is braked using the electric motor 3a, the drag mechanism 3 having a simple configuration can be obtained. Further, the electric motor 3 a is arranged in the axial direction with the spool 2, the electric motor 3 a is provided with a hollow shaft 21, and the spool shaft 4 is arranged through the hollow shaft 21. With this configuration, it is possible to reduce the diameter of the spool body 2a of the spool 2 while suppressing an increase in the spool axial length of the dual-bearing reel 100 using the electric motor 3a having the magnet 22 and the coil 23. . Furthermore, since the rotation of the spool 2 is accelerated by the first rotation transmission mechanism 5 and the electric motor 3a is rotated, the rotation speed of the electric motor 3a can be made faster than the rotation speed of the spool 2 during the drag operation. . As a result, the drag force can be increased and made smooth while facilitating the control of the electric motor 3a.

<Features>
The above embodiment can be expressed as follows.

  (A) The double-bearing reel 100 is a reel that feeds a fishing line forward. The dual-bearing reel 100 includes a reel body 1, a handle 6, a spool 2, a spool shaft 4, a drag mechanism 3, a first rotation transmission mechanism 5, a setting member 10, and a first control unit 11a. Prepare. The handle 6 is for thread winding provided on the side of the reel body 1. The spool 2 is rotatable with respect to the reel body 1. The spool shaft 4 rotates the spool 2 by the rotation of the handle 6. The drag mechanism 3 includes an electric motor 3a that brakes the rotation of the spool 2 in the yarn feeding direction. The first rotation transmission mechanism 5 includes a first planetary gear mechanism 28 that transmits 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 body 1 and is configured to set and operate the drag force of the drag mechanism 3. The first control unit 11a controls the electric motor 3a according to the movement 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 that transmits rotation between the electric motor 3 a and the spool shaft 4 and the spool 2. The first planetary gear mechanism 28 is rotated when one of the first sun gear 30, the first carrier 32, and the ring gear 33 is constrained, and rotates idle without transmitting any rotation when none of the first planetary gear mechanisms 28 is constrained. Here, when the handle 6 is operated to rotate the spool 2 via the spool shaft 4, the torque of the handle 6 is controlled by controlling the electric motor 3a so that the hollow shaft 21 of the electric motor 3a does not reverse. It can be configured not to flow backward to the electric motor 3a via the rotation transmission mechanism 5. As a result, a configuration in which the electric motor 3a is not rotated during manual winding can be realized, and the handle 6 can be smoothly rotated when the spool 2 is manually wound.

  (B) The electric motor 3a may be arranged side by side in the spool 2 and the spool axial direction. In this case, the first rotation transmission mechanism 5 can be easily disposed between the spool 2 and the electric motor 3a.

  (C) The electric motor 3a may have a hollow shaft 21 through which the spool shaft 4 can pass. The spool shaft 4 may be rotatably supported by the reel body 1 and the spool 2 may be rotatably supported by the spool shaft 4. In this case, since the spool shaft 4 can be disposed through the hollow shaft 21, even if the electric motor 3a and the spool 2 are disposed side by side in the axial direction, the axial length of the double-bearing reel 100 is increased. Can be suppressed.

  (D) The first controller 11a may control the electric motor 3a in a regenerative braking mode in which the electric motor 3a performs regenerative braking. In this case, a strong drag force can be obtained by regenerative braking.

  (E) The first control unit 11a may control the electric motor 3a in a drive braking mode in which the electric motor 3a is torque-controlled so as to drive the spool 2. In this case, it is possible to obtain a drag force that is weaker than the drag force by regenerative braking by controlling the torque of the electric motor 3a.

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

  (G) When the set drag force SD set by the setting member 10 is equal to or less than the first drag force D1, the first controller 11a may control the electric motor 3a in the drive braking mode. In this case, the setting member 10 can set a drag force that is weaker than the regenerative braking force, and can set the drag force in a wide range.

  (H) The first controller 11a may control the electric motor 3a in the first drive braking mode in which the electric motor 3a is torque-controlled so as to drive the spool 2 in the yarn winding direction. In this case, since the spool 2 is driven in the yarn winding direction by the electric motor 3a, a strong drag force can be obtained in the drive braking mode.

  (I) The first control unit 11a may control the electric motor 3a in the second drive braking mode in which the electric motor 3a is torque-controlled so as to drive the spool 2 in the yarn feeding direction. In this case, since the spool 2 is driven in the yarn take-out direction by the electric motor 3a, a weaker drag force can be obtained in the drive braking mode than in the first drive braking mode.

  (J) When the set drag force SD set by the setting member 10 is equal to or less than the first drag force D1 and exceeds the second drag force D2 smaller than the first drag force D1, The electric motor 3a may be controlled in the one-drive braking mode. In this case, the setting member 10 can set the drag force between the drag force in the regenerative braking mode and the drag force in the second drive control mode.

  (K) The first control unit 11a may control the electric motor 3a in the second drive braking mode when the set drag force SD set by the setting member 10 is equal to or less than the second drag force. In this case, since the spool 2 is driven in the yarn feeding direction by the electric motor 3a, the setting member 10 can set a drag force weaker than that in the first drive braking mode.

  (L) The double-bearing reel 100 further includes a second rotation transmission mechanism 7 that transmits the rotation of the handle 6 to the spool shaft 4, and a reverse rotation prohibiting mechanism 8 that prohibits the rotation of the spool shaft 4 in the yarn unwinding direction. Also good. In this case, the rotation of the handle 6 can be transmitted to the spool 2.

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