Description

  The present invention relates to a fishing reel, and more particularly to a dual bearing reel for cutting a fishing line forward.

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

Japanese Utility Model Publication No. 50-21993

  In the conventional drag mechanism, an electric motor capable of rotating in both directions is directly connected to the spool via the reduction gear. For this reason, at the time of a manual winding operation in which the spool is rotated in the line winding direction by the handle, the output shaft of the electric motor is accelerated and rotated in the normal direction. When the output shaft of the electric motor rotates, regenerative braking occurs and braking force acts on the steering wheel, making it difficult to smoothly turn the steering wheel during manual winding operation.

  An object of the present invention is to make it possible to smoothly turn the handle when manually operating the spool even if the drag force is generated by the electric motor.

  The dual bearing reel according to the present invention is a reel that feeds 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 thread winding provided on the side of the reel body. The spool is rotatable relative to the reel body. The spool shaft rotates the spool by rotation of the handle. The drag mechanism has an electric motor that brakes the rotation of the spool in the line feed direction. The first rotation transmission mechanism has a planetary gear mechanism that transmits rotation between the electric motor and the spool shaft, and the spool. The drag setting member is movably provided on the reel body, and configured to set and operate the drag force of the drag mechanism. The drag control unit controls the electric motor in accordance with 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 and the spool shaft and the spool. When one of the sun gear, the carrier, and the ring gear is restrained, the planetary gear mechanism transmits the rotation, and when none of the sun gear, the carrier and the ring gear is restrained, the planetary gear mechanism idles without transmitting the rotation. Here, when the handle is operated to rotate the spool, the torque of the handle is configured not to flow back to the electric motor through 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 can be realized in which the electric motor is not rotated during manual winding, and the handle can be smoothly rotated when performing manual winding operation of the spool.

  The electric motor may be arranged side by side in the spool and in the spool axial 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 by the reel body, and the spool may be rotatably supported by 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 subjected to torque control so as to drive the spool. In this case, by controlling the torque of the electric motor, it is possible to obtain a drag force weaker than the drag force by the regenerative braking.

  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, the drag setting member can set the drag force weaker than the regenerative braking force, and can set the drag force 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 subjected to torque control so as to drive the spool in the line winding direction. In this case, since the spool is driven in the line 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 subjected to torque control so as to drive the spool in the line unwinding direction. In this case, since the spool is driven in the line 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 the second drag force smaller than the first drag force. May be In this case, the drag setting member can set the drag force between the drag force in the regenerative braking mode and the drag force in the second drive control mode.

  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 line unwinding direction by the electric motor, the drag setting member can set a drag force weaker than in the first drive braking mode.

  The dual-bearing reel may further include a second rotation transmission mechanism for transmitting the rotation of the handle to the spool shaft, and a reverse rotation inhibiting mechanism for prohibiting the rotation of the spool shaft in the line unwinding 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 rotated when the spool is manually wound.

The second rotation transmission mechanism 7 has a first gear 40, a second gear 41, a third gear 42, a fourth gear 43, and an engagement piece 44. The first gear 40 has a larger number of teeth than the second gear 41 and is a gear for high-speed winding. The first gear 40 and the second gear 41 are rotatably supported by the drive shaft 19. The third gear 42 and fourth gear 4 3 is integrally rotatably coupled to the spool shaft 4. The first gear 40 meshes with the third gear 42. The second gear 41 meshes with the fourth gear 43.

  In the second rotation transmission mechanism 7 having such a configuration, when the operation shaft 45 is pushed to the left in FIG. 2, the engagement piece 44 is disposed on the second gear 41. Thus, the rotation of the handle 6 in the line winding direction is transmitted to the fourth gear 43 via the second gear 41, and the spool shaft 4 and the spool 2 rotate at low speed. On the other hand, when the slide type stopper 46 (see FIG. 1) is slid to pull out the operation shaft 45 to the right in FIG. 2, the engagement piece 44 is disposed on the first gear 40. As a result, the rotation of the handle 6 is transmitted to the third gear 42 via the first gear 40, and the spool shaft 4 and the spool 2 rotate at high speed.

Have. The ratchet wheel 50 has a second slit 50 b at its central portion, which engages with both projecting ends of the second pin member 27.

The stopper claw 52 is separated from the ratchet teeth 50a when the spool shaft 4 is rotated in the line winding direction by a control member (not shown). Also, when the spool shaft 4 rotates in the direction opposite to the line winding direction, it engages with the ratchet teeth 50a. Thus, the rotation (reverse rotation) of the spool shaft 4 in the line feeding direction is prohibited. In the present embodiment, two stopper claws 52 are provided in order to inhibit the reverse rotation of the ratchet wheel 50 at a rotational phase that is half the rotational phase determined by the number of the ratchet teeth 50a. Accordingly, the spool shaft 4 is usually not rotate the feeding way direction yarns.

<Display section>
The display unit 9 is provided to display the drag force set by the setting member 10 in units of N (newtons), as shown in FIG. The display unit 9 has a liquid crystal display 9a capable of displaying numerical values and figures. In addition, when the sensor which detects the frequency | count of rotation from a position (for example, thread winding trunk | drum 2a) is provided in the predetermined | prescribed spool 2, you may calculate and display the delivery length of a fishing line. In addition, 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 the operation of the operation button 54.

<Setting member>
The setting member 10 has the same shape as the drag lever of a conventional mechanical drag mechanism, as shown in FIGS. 1 and 2. The setting member 10 is provided to set the drag force generated by the electric motor 3a in a plurality of stages (for example, in the range of 10 stages to 40 stages). The setting member 10 is supported by the first side cover 13 so as to be pivotable within a range of, for example, 120 degrees from a braking release position indicated by a two-dot chain line in FIG. The setting member 10 has 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 integrally rotatably coupled 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. The setting member 10 can be positioned in multiple stages by a positioning mechanism (not shown). In the setting member 10, the drag force can be set, for example, up to 400N.

<Control unit>
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 drag control unit. The first control unit 11 a is accommodated in the display unit 9 and controls the electric motor 3 a according to the movement position (swinging 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 (swinging 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 the operation button 54, the rotational position sensor 24, the spool sensor 58, the liquid crystal display 9a, the electric motor 3a, and the first wireless communication unit 55. The storage unit 60 is electrically connected. The spool sensor 58 can detect the rotational speed, the number of rotations, and the rotational direction of the spool 2 by detecting the magnetic field of the detection magnet 58a. When the spool sensor 58 detects the rotational direction, the first control unit 11a can detect the rotation of the spool 2 in the line unwinding 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 the small-scale wireless communication standard. The phase sensor 56 and the second wireless communication unit 57 are electrically connected to the second control unit 11 b. The second wireless communication unit 57 can communicate with the first wireless communication unit 55 according to the small-scale wireless communication standard.

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

Next, an example of the setting process of the braking mode by the first control unit 11a will be described based on the flowchart shown in 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 S2, the first control unit 11a causes the liquid crystal display 9a of the display unit 9 to display the read setting drag force SD. In step S3, the first control unit 11a determines whether the read set drag force SD exceeds the first drag force D1 (for example, 200 N). If the set drag force SD read in 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 control unit 11a determines whether the read set drag force SD exceeds a second drag force D2 (eg, 100 N) 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 the set drag force SD exceeds "0", that is, determines whether the setting member 10 is at the braking release position.

  If it is determined that the set drag force SD is larger than the first drag force 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 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 at a duty ratio corresponding to the set drag force SD.

  If it is determined that the set drag force SD is greater than the second drag force D2 and smaller than or equal to the first drag force 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 a first drive braking mode in which the braking force is smaller than that of 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 line winding direction at a duty ratio corresponding to the set drag force SD. That is, when the electric motor 3a is driven in the line winding direction, the current supplied to the electric motor 3a is controlled at 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 control unit 11a proceeds the process from step S5 to step S8. In step S8, the first control unit 11a sets the braking mode to a 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 performs torque control of the electric motor 3a so as to drive the spool 2 in the line unwinding direction at a duty ratio corresponding to the set drag force SD. That is, when the electric motor 3a is driven in the line unwinding direction, the current supplied to the electric motor 3a is controlled at a duty ratio corresponding to the set drag force SD. Here, since the spool 2 is braked in three different levels of braking mode in three levels of strength, it is possible to control the drag mechanism 3 with high accuracy in accordance with 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 can not perform regenerative braking. In this state, when the fishing line is drawn out, the fishing line is drawn out from the spool 2 by traveling of the fishing boat. When the fishing line has been unwound 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 the game is caught by the prey, and the handle 6 is rotated in the clockwise direction 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 accelerated and transmitted to the spool 2 via the first rotation transmission mechanism 5. Specifically, when the handle 6 is rotated in the clockwise direction in FIG. 1, the spool shaft 4 rotates counterclockwise in FIG. This rotation is transmitted by the first pin member 26 to the second carrier 36, and the second carrier 36 rotates counterclockwise. When the second carrier 36 rotates, the second sun gear 34 is accelerated and rotated counterclockwise through the second planetary gear 35. As a result, the first carrier 32 integrally rotating with the second sun gear 34 is rotated counterclockwise, and the spool 2 is wound by the first planetary gear 31 in the same direction as the spool shaft 4 (counterclockwise in FIG. 1). Increase speed in the direction. At this time, the first sun gear 30 controls the electric motor 3a to fix the hollow shaft 21 of the electric motor 3a, whereby the torque of the handle 6 is transferred to the electric motor 3a via the first rotation transmission mechanism 5. It can be configured not to backflow. For this reason, since the hollow shaft 21 connected integrally rotatably with the first sun gear 30 also does not rotate, the braking force by the electric motor 3a is not generated at the time of manual winding. As a result, when the spool 6 is rotated by the handle 6 in the thread winding direction, the handle 6 can be smoothly rotated.

  In the regenerative braking mode, when the pulling force of the prey becomes greater than the set drag force SD, the spool 2 rotates in the line unwinding direction (clockwise in FIG. 1). When the spool 2 rotates in the line unwinding direction, the second carrier 36 connected to the spool shaft 4 acts on the reverse rotation prohibiting mechanism 8 via the spool shaft 4, and thus clockwise rotation in FIG. 1 is prohibited. For this reason, the second sun gear 34 rotates at an increased speed in the counterclockwise direction in FIG. By this rotation, the first carrier 32 is rotated at the same speed in the same direction, and the first sun gear 30 is accelerated and rotated 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 rotation of the spool 2 in the line unwinding 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 prey becomes larger than the set drag force SD, the spool 2 rotates in the line unwinding direction (clockwise in FIG. 1). When this rotation is detected by the output of the spool sensor 58, the first control unit 11a performs torque control of the electric motor 3a in accordance with the set drag force SD so as to drive the spool 2 in the line winding direction. At this time, the torque is corrected according to the thread winding diameter. This makes it possible to obtain a stronger drag force than in the second drive braking mode.

  In the second drive braking mode, when the pulling force of the prey becomes larger than the set drag force SD, the spool 2 rotates in the line unwinding direction (clockwise in FIG. 1). When this rotation is detected by the output of the spool sensor 58, the first control unit 11a performs torque control of the electric motor 3a in accordance with the set drag force SD so as to drive the spool 2 in the line unwinding direction. At this time, the torque is corrected according to the thread winding 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 3a is disposed in line with the spool 2 in the axial direction, and the electric motor 3a is provided with the hollow shaft 21 and the spool shaft 4 is provided through the hollow shaft 21. With this configuration, it is possible to reduce an increase in the length in the spool axial direction of the dual-bearing reel 100 using the electric motor 3a having the magnet 22 and the coil 23, and to reduce the diameter of the bobbin trunk 2a of the spool . Furthermore, since the rotation of the spool 2 is accelerated by the first rotation transmission mechanism 5 to rotate the electric motor 3a, the rotation speed of the electric motor 3a can be made faster than the rotation speed of the spool 2 at the time of drag operation. . As a result, the drag force can be made large and smooth while facilitating control of the electric motor 3a.

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

  (A) The dual bearing reel 100 is a reel for delivering the 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 relative to the reel body 1. The spool shaft 4 rotates the spool 2 by the rotation of the handle 6. The drag mechanism 3 has an electric motor 3 a that brakes the rotation of the spool 2 in the line unwinding direction. The first rotation transmission mechanism 5 has 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 configured to set and operate the drag force of the drag mechanism 3. The first control unit 11 a controls the electric motor 3 a according to the movement position of the setting member 10.

  In the dual-bearing reel 100, the first rotation transmission mechanism 5 has a first planetary gear mechanism 28 that transmits rotation between the electric motor 3a and the spool shaft 4 and the spool 2. The rotation of the first planetary gear mechanism 28 is transmitted when any one of the first sun gear 30, the first carrier 32, and the ring gear 33 is restrained, and when none is restrained, the first planetary gear mechanism 28 idles without transmitting the rotation. Here, when the handle 2 is operated to rotate the spool 2 via the spool shaft 4, the torque of the handle 6 is firstly controlled by controlling the electric motor 3a so that the hollow shaft 21 of the electric motor 3a does not reversely rotate. It can be configured so as not to flow back to the electric motor 3a side via the rotation transmission mechanism 5. Thus, a configuration can be realized in which the electric motor 3a is not rotated during manual winding, and when the spool 2 is manually wound, the handle 6 can be smoothly rotated.

  (B) The electric motor 3a may be arranged side by side with the spool 2 in 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, the axial length of the dual-bearing reel 100 can be increased even if the electric motor 3 a and the spool 2 are disposed side by side in the axial direction. It can be suppressed.

  (D) The first control unit 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, a drag force weaker than the drag force by the regenerative braking can be obtained by controlling the torque of the electric motor 3a.

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

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

  (H) The first control unit 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 line winding direction. In this case, since the spool 2 is driven in the line 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 line unwinding direction. In this case, since the spool 2 is driven in the line unwinding direction by the electric motor 3a, it is possible to obtain a drag force weaker than in the first drive braking mode in the drive braking mode.

  (J) If the set drag force SD set by the setting member 10 is less than or equal to the first drag force D1 and exceeds the second drag force D2 smaller than the first drag force D1, the first control unit 11a The electric motor 3a may be controlled in the 1 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 line unwinding direction by the electric motor 3a, the setting member 10 can set a drag force weaker than in the first drive braking mode.

  (L) The double-bearing reel 100 further includes a second rotation transmission mechanism 7 for transmitting the rotation of the handle 6 to the spool shaft 4 and a reverse rotation inhibiting mechanism 8 for prohibiting the spool shaft 4 from rotating in the line-out direction. It is 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.
