Description

Dual bearing reel {DUAL-BEARING REEL}

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 drag mechanism for braking the rotation of the spool in the thread take-off direction. BACKGROUND ART [0002] In a double-bearing reel having a conventional drag mechanism, a double-bearing reel for braking a spool using an electric motor is known (see, for example, Patent Document 1). In a conventional double-bearing reel, a drag mechanism is constituted by an electric motor having a speed reducer. The output shaft of the electric motor is directly coupled to the spool through a speed reducer. In the conventional drag mechanism using the electric motor, the electric motor is operated as a generator. Then, the electric motor brakes the spool by regenerative braking which consumes the electromotive force (electromotive force) generated by the rotation of the spool in the row discharging direction by the variable resistor.

Japanese Utility Model Official Gazette, No. 50-21993

In the conventional drag mechanism, an electric motor capable of rotating in both directions is disposed directly in contact with the spool through the speed reducer. Therefore, when the spool is manually operated to rotate the spool in the line-winding direction by the handle, the output shaft of the electric motor is rotated in the forward rotation direction. When the output shaft of the electric motor rotates, regenerative braking is generated to apply braking force to the handle, and it is difficult to smoothly turn the handle when the manual operation is performed.

An object of the present invention is to smoothly rotate a handle when manually operating a spool even when a drag force is generated by an electric motor.

A double-bearing reel according to the present invention is a reel for releasing a fishing line forward. The dual bearing reel includes a reel unit, a handle, a spool, a spool shaft, a drag mechanism, a first rotation transmitting mechanism, a drag setting member, and a drag control unit. The handle is for winding a string which is provided on a side portion of the reel main body. The spool is rotatable with respect to the reel main body. The spool shaft rotates the spool by the rotation of the handle. The drag mechanism has an electric motor for braking the rotation of the spool in the line discharge 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 unit, and is configured to set 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. The planetary gear mechanism rotates when any one of the sun gear, the carrier, and the ring gear is restrained, and idles without transmitting rotation unless all of them are restrained. Here, when the spool is rotated by operating the handle, the torque of the handle is prevented from flowing back to the electric motor via the planetary gear mechanism by controlling the electric motor so that the shaft of the electric motor is not reversed . As a result, it is possible to realize a structure in which the electric motor is not rotated when the number is equal, and the handle can be turned smoothly when the spool is manually operated.

The electric motor may be disposed in parallel to the spool and 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 (hollow shaft) through which the spool shaft can pass. The spool shaft may be rotatably supported on the reel unit, 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, even if the electric motor and the spool are arranged side by side in the axial direction, the increase in the axial length of the both bearing reels can be suppressed.

The drag control unit may control the electric motor in the regenerative braking mode in which the electric motor is regeneratively braked. 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 for torque control of the electric motor so as to drive the spool. In this case, a drag force that is weaker than the drag force by the regenerative braking can be obtained by torque-controlling 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, the drag setting member can set a drag force that is weaker than the regenerative braking force, and the drag force can be set to a wide range.

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

The drag control unit may control the electric motor in the first drive braking mode when the drag force set by the drag setting member is equal to or smaller than the first drag force and exceeds the second drag force smaller than the first drag force. 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 by the electric motor in the lane-releasing direction, the drag setting member can set the drag force weaker than the first drive braking mode.

The double bearing reel may further include a second rotation transmitting mechanism for transmitting the rotation of the handle to the spool shaft and a reverse prevention mechanism for prohibiting rotation of the spool shaft in the line releasing 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 whose maintenance is easy.

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

In the setting member 10, the drag force can be set up to 400 N, for example.

<Control section>

As shown in Fig. 5, the control section 11 has a first control section 11a and a second control section 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 drag control unit. The first control unit 11a and the second control unit 11b may be examples of the drag control unit. The first control section 11a is accommodated in the display section 9 and controls the electric motor 3a in accordance with the movement position (swing position) of the setting member 10. [ The second control section 11b is provided on the first side cover 13 and transmits a signal corresponding to the movement position (swing position) of the setting member 10 to the first control section 11a .

5, the first control section 11a is provided with an operation button 54, a rotation position sensor 24, a spool sensor 58, a liquid crystal display 9a, an electric motor 3a, The first wireless communication unit 55, and the storage unit 60 are electrically connected to each other. The spool sensor 58 is capable of detecting the rotational speed, the number of rotations, and the rotational direction of the spool 2 by detecting the magnetic field of the detecting magnet 58a. The first control section 11a can detect the rotation of the spool 2 in the row ejection direction by the spool sensor 58 detecting the rotation direction. The first wireless communication unit 55 is provided to enable the first control unit 11a and the second control unit 11b to communicate with each other in accordance with a small-scale wireless communication standard. In the second control section 11b, the phase sensor 56 and the second wireless communication section 57 are electrically connected. The second wireless communication unit 57 is capable of communicating with the first wireless communication unit 55 in accordance with the small-scale wireless communication standard.

The first control section 11a controls the electric motor 3a in three braking modes of the regenerative braking mode, the first drive braking mode and the second drive braking mode in accordance with the operation position of the setting member 10 do.

Next, an example of the braking mode setting process by the first control section 11a will be described based on the flowchart shown in Fig. Incidentally, Fig. 6 is an example of control, and the present invention is not limited to the control shown in Fig.

6, the first control section 11a reads the setting drag force SD of the setting member 10 from the detection value of the phase sensor 56 transmitted from the second control section 11b. In step S2, the first control section 11a causes the liquid crystal display 9a of the display section 9 to display the read setting drag force SD. In step S3, the first control unit 11a determines whether the read setting drag force SD exceeds the first drag force D1 (for example, 200N). If the read setting drag force SD is equal to or smaller than the first drag force D1, the first control section 11a advances the process from step S3 to step S4. In step S4, the first control unit 11a determines whether or not the read setting drag force SD exceeds the second drag force D2 (for example, 100N) smaller than the first drag force D1 . The first control unit 11a causes the first control unit 11a to proceed from step S4 to step S5 when the set drag force SD is equal to or smaller than the second drag force D2. In step S5, the first control section 11a determines whether or not the set drag force SD exceeds &quot; 0 &quot;. That is, whether or not the setting member 10 is in 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 section 11a advances the process from step S3 to step S6. In step S6, the first control section 11a sets the braking mode to the regenerative braking mode with a large braking force. In the regenerative braking mode, the first control section 11a controls the current generated from the electric motor 3a at a duty ratio according 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 smaller than the first drag force D1, the first control section 11a advances the processing from step S4 to step S7. In step S7, the first control section 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 control section 11a torque-controls 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 flowing through the electric motor 3a is controlled to a duty ratio corresponding to the set drag force SD.

If it is determined that the setting drag force SD is equal to or smaller than the second drag force D2 and exceeds "0", the first control section 11a advances the process from step S5 to step S8. In step S8, the first control section 11a sets the braking mode to the second drive braking mode in which the braking force is smaller than the first drive braking mode. In the second drive braking mode, the first control section 11a torque-controls the electric motor 3a so as to drive the spool 2 in the lane departure direction at a duty ratio corresponding to the set drag force SD. That is, when driving the electric motor 3a in the line-releasing direction, the current flowing through the electric motor 3a is controlled to a duty ratio corresponding to the set drag force SD. In this case, since the spool 2 is braked in the other braking mode in the third step, it is possible to control the drag mechanism 3 with accuracy (accuracy) in accordance with the set drag force.

&Lt; Control operation when fishing is performed &gt;

When the fishing line is released, 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 released, the fishing line is discharged from the spool 2 by traveling of the fishing boat. When the fishing line is released to some extent, the setting member 10 is operated to set a desired drag force. The value of the setting drag force SD is displayed on the liquid crystal display 9a.

When the catch is caught in the preparation and the handle 6 is rotated in the line-winding direction in Fig. 1, the rotation is transmitted to the spool shaft 4 through the second rotation transmission mechanism 7. The rotation of the spool shaft 4 is transmitted to the spool 2 through the first rotation transmitting mechanism 5 at an increased speed. Specifically, when the handle 6 rotates in the clockwise direction 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 at an increased speed in the counterclockwise direction through the second planetary gear 35. The first carrier 32 rotating integrally with the second sun gear 34 rotates in the counterclockwise direction and the first planetary gear 31 rotates the spool 2 in the axial direction of the spool shaft 4 And the speed is increased in the line winding direction in the same direction (counterclockwise in FIG. 1). At this time, by controlling the electric motor 3a to fix the hollow shaft 21 of the electric motor 3a, the torque of the handle 6 is transmitted through the first rotation transmission mechanism 5 to the electric motor 3a In the present invention. Therefore, the braking force by the electric motor 3a does not occur at the same time because the hollow shaft 21 connected to the first sun gear 30 in a rotatable manner is not rotated. As a result, the handle 6 can be smoothly turned when the spool 2 is manually operated to rotate the spool 2 in the line-winding direction by the handle 6.

In the regenerative braking mode, when the pulling force of the catch is larger than the set drag force SD, the spool 2 rotates in the line discharge direction (clockwise direction in Fig. 1). The second carrier 36 connected to the spool shaft 4 acts on the reverse rotation prohibiting mechanism 8 through the spool shaft 4 when the spool 2 rotates in the line releasing direction, Is prohibited. Therefore, the second sun gear 34 is rotated 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 rotated at an increased speed in the same direction (counterclockwise direction in FIG. 1). When the first sun gear 30 is rotated at an increased speed in the counterclockwise direction, the magnet 22 is rotated at an increased speed in the same direction so that the rotation of the spool 2 in the line-releasing direction by the regenerative braking force set by the setting member 10 Braking.

In the first drive braking mode, when the pulling force of the catch is larger than the set drag force SD, the spool 2 rotates in the lane departure direction (clockwise direction in Fig. 1). When the rotation is detected by the output of the spool sensor 58, the first control section 11a drives the electric motor 3a in accordance with the set drag force SD so as to drive the spool 2 in the line- Torque control. At this time, correct the torque according to the winding direction of the line. Thereby, a stronger drag force than the second drive braking mode can be obtained.

In the second drive braking mode, when the pulling force of the catch is larger than the set drag force SD, the spool 2 rotates in the line discharge direction (clockwise direction in Fig. 1). When the rotation is detected by the output of the spool sensor 58, the first control section 11a drives the electric motor 3a in accordance with the set drag force SD so as to drive the spool 2 in the line- Torque control. At this time, correct the torque according to the winding direction of the line.

Here, since the spool 2 is braked by using the electric motor 3a, the drag mechanism 3 having a simple structure can be obtained. An electric motor 3a is disposed in parallel with the spool 2 in the axial direction and the electric motor 3a is provided with a hollow shaft 21. The spool shaft 4 passes through the hollow shaft 21, . With this configuration, an increase in the axial length of the double-bearing reel 100 using the electric motor 3a having the magnets 22 and the coils 23 is suppressed, It is possible to reduce the diameter of the second electrode 2a. Further, since the rotation of the spool 2 is increased by the first rotation transmitting mechanism 5 and the electric motor 3a is rotated, the rotational speed of the electric motor 3a is reduced to the rotational speed of the spool 2 during the drag operation. It can be made faster than the rotation speed. As a result, the drag force can be made large and 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 discharges the fishing line forward. The dual bearing reel 100 includes a reel unit 1, a handle 6, a spool 2, a spool shaft 4, a drag mechanism 3, a first rotation transmitting mechanism 5, A setting member 10, and a first control unit 11a. The handle 6 is provided on the side of the reel unit 1 for winding a line. The spool (2) is rotatable with respect to the reel unit (1). The spool shaft (4) rotates the spool (2) by rotating the handle (6). The drag mechanism 3 has an electric motor 3a for braking the rotation of the spool 2 in the line discharging direction. The first rotation transmission mechanism 5 has an electric motor 3a and a spool shaft 4 and a first planetary gear mechanism 28 for transmitting rotation between the spool 2 and the electric motor 3a. The setting member 10 is configured to be movable on the reel unit 1 and is configured to set and operate the drag force of the drag mechanism 3. [ The first control section 11a controls the electric motor 3a in accordance with the movement position of the setting member 10. [

In this double bearing reel 100, the first rotation transmitting mechanism 5 includes a first planetary gear mechanism (not shown) for transmitting rotation between the electric motor 3a and the spool shaft 4 and the spool 2, (28). The first planetary gear mechanism 28 transmits rotation when any one of the first sun gear 30, the first carrier 32 and the ring gear 33 is restrained. Or revolve. Here, when the spool 2 is rotated through the spool shaft 4 by operating the handle 6, the electric motor 3a is controlled so that the hollow shaft 21 of the electric motor 3a is not reversed The torque of the handle 6 does not flow back to the electric motor 3a via the first rotation transmitting mechanism 5. [ As a result, it is possible to realize a structure in which the electric motor 3a is not rotated when the number is the same, and the handle 6 can be turned smoothly when the spool 2 is manually operated.

(B) The electric motor 3a may be disposed in parallel with the spool 2 in the axial direction of the spool. In this case, the first rotation transmitting 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 on the reel unit 1 and the spool 2 may be rotatably supported on 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 arranged side by side in the axial direction, An increase in the length in the axial direction can be suppressed.

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

(E) The first control section 11a may control the electric motor 3a in the 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 that is weaker than the drag force by regenerative braking can be obtained by torque-controlling the electric motor 3a.

(F) The first control section 11a controls 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 It is acceptable. In this case, the setting member 10 can set a strong drag force.

(G) The first control section 11a controls 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 It is acceptable. In this case, the setting member 10 can set a drag force that is weaker than the regenerative braking force, and the drag force can be set to a wide range.

(H) The first control section 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 section 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 spool direction. In this case, since the spool 2 is driven in the lane release direction by the electric motor 3a, a dragging force weaker than the first drive braking mode can be obtained in the drive braking mode.

(J) The first control unit 11a determines whether or not the setting drag force SD set by the setting member 10 is equal to or smaller than the first drag force D1 and smaller than the first drag force D1, (D2), the electric motor 3a may be controlled in the first drive braking mode. 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 setting member 10.

(K) The first control section 11a controls 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 Do. In this case, since the spool 2 is driven by the electric motor 3a in the lane-releasing direction, the setting force of the setting member 10 allows a weaker drag force to be set than in the first drive braking mode.

(L) The double-bearing reel 100 includes a second rotation transmitting mechanism 7 for transmitting the rotation of the handle 6 to the spool shaft 4 and a second rotation transmitting mechanism 7 for inhibiting rotation of the spool shaft 4 in the line- It may be further provided with a reverse inhibition mechanism 8. 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 whose maintenance is easy.
