Description

Switching device for fishing reel

  The present invention relates to a switching device, and more particularly to a fishing reel switching device having a spool for winding that rotates by rotation of a handle.

  As a dual-bearing reel or electric reel, which is a ship reel, a clutch switching device for stopping a fed fishing line at a shelf position is driven by a driving body such as a solenoid. Recently, a technique for driving a clutch switching mechanism using reverse rotation of a motor for rotating a spool in an electric reel has been developed (see Patent Document 1).

  The conventional electric reel includes a reel body having a handle, a spool rotatably mounted on the reel body, a motor that rotates the spool, and a planetary gear mechanism that transmits the rotation of the motor to the spool. Mechanism. Further, a clutch mechanism capable of turning on and off the spool in a freely rotatable state and a yarn winding enabled state, and a clutch switching mechanism for switching the clutch mechanism between a clutch off state and a clutch on state are provided. The clutch mechanism is provided in the middle of the rotation transmission mechanism. The clutch switching mechanism includes a clutch operation lever, a clutch operation mechanism that is operated by the clutch operation lever, and a clutch return mechanism that returns the clutch mechanism to a yarn winding-capable state in conjunction with the rotation of the handle. The clutch operation lever is mounted on the reel body so as to be swingable between a clutch-on position and a clutch-off position. The clutch operating mechanism switches the clutch mechanism between a clutch-on state and a clutch-off state by moving the clutch operating member. When the clutch mechanism is in the clutch-off state, the clutch return mechanism returns the clutch mechanism to the clutch-on state via the clutch operation mechanism in conjunction with the rotation of the handle in the yarn winding direction.

  In addition to the above configuration, the conventional electric reel includes a one-way clutch that is supported by the reel body so as to be rotatable and prohibits reverse rotation of the motor, and a clutch return mechanism that links the one-way clutch and the clutch switching mechanism. . The one-way clutch is a roller clutch having an inner ring, an outer ring, and a roller disposed therebetween. The inner ring is fixed to the output shaft of the motor, for example, by press fitting. The clutch return mechanism includes a gear portion formed on the outer ring outer periphery of the one-way clutch, an intermediate gear that meshes with the gear portion, and a rack that is formed in the clutch operation mechanism and meshes with the intermediate gear. The clutch operation lever is mounted on the reel body in a state in which the swing range is restricted so that the one-way clutch can be prevented from rotating in the reverse direction so as not to swing further on the clutch-on position side. Therefore, the one-way clutch can be reversed until the clutch operating lever reaches the clutch-on position.

  In such a conventional electric reel, when the clutch operating lever is operated to the clutch-off position, the clutch mechanism can be fed out by its own weight attached to the tip of the fishing line when the clutch mechanism is in the clutch-off state. For example, when the device reaches a predetermined shelf, the motor is reversed. When the motor is reversely rotated, the one-way clutch is reversely rotated and its rotation is transmitted from the gear to the rack, the clutch operating mechanism turns the clutch mechanism into the clutch-on state, and the clutch operation lever returns to the clutch-on position. When the clutch operating lever returns to the clutch-on position, it can no longer rotate, preventing the one-way clutch from reversing and preventing the motor from reversing. This stops fishing line feeding. In this state, when the motor is rotated forward in the line winding direction, the spool rotates to wind up the fishing line.

The operation of returning the clutch mechanism to the clutch-on state can be performed by using the clutch return mechanism by rotating the handle in the yarn winding direction, and by operating the clutch operation lever from the clutch-off position to the clutch-on position. Can also be done.

  In the conventional configuration, the clutch is switched by rotating the motor in reverse to return the clutch mechanism to the clutch-on state. In reels, a motor with a thin output shaft is often used because of the need to reduce the size and weight. If a motor with such a thin output shaft is used as the drive body of the clutch switching mechanism, a shock torque load is likely to be generated at the start of the switching operation in the case of the clutch switching mechanism. There is a risk that a driving part such as a gear fixed by press-fitting into the inner ring or an inner ring of a one-way clutch or a rotor may idle.

  An object of the present invention is to suppress idling of a driving component fixed to an output shaft of a motor in a fishing reel switching device that uses a motor as a driving body.

  A fishing reel switching device according to a first aspect of the present invention is a fishing reel switching device having a spool for spool that rotates by rotation of a handle, and includes a mechanism unit, a drive unit, a switching unit, a motor control unit, It has. The mechanism unit can be switched to a plurality of states. The drive unit includes a motor having an output shaft and a drive component fixed to the output shaft, and operates by rotation of the drive component. The switching unit is arranged between the drive unit and the mechanism unit, and switches the state of the mechanism unit to any one by the power of the drive unit. The motor control unit controls the motor by gradually increasing the voltage from the first voltage to a second voltage higher than the first voltage and operable by the switching unit when the switching unit performs the switching operation by the power of the driving unit. Is.

  In this switching device, when the state of the mechanism unit is switched, the motor of the driving unit is controlled by the motor control unit to rotate the driving component, and the switching unit is operated by the rotation of the driving component, and the mechanism unit is in any of a plurality of states. Can be switched. During this switching operation, a first voltage lower than the operable second voltage is applied to the motor, and then gradually increases toward the second voltage. Here, when the switching operation is performed using the motor, the voltage applied to the motor is gradually increased from the first voltage to the operable second voltage. The impact torque load does not occur, and the idling of the drive component fixed to the output shaft is less likely to occur.

  A fishing reel switching device according to a second aspect of the present invention is the device according to the first aspect, further comprising a PWM drive circuit for pulse-width modulation driving the motor, wherein the motor control unit has a third voltage whose power supply voltage is equal to or higher than the second voltage. In this case, the duty ratio applied to the PWM drive circuit is gradually increased from a value corresponding to the first voltage to a value corresponding to the second voltage. In this case, since the motor is controlled by the duty ratio of PWM drive, the accuracy of the motor can be accurately performed while saving power consumption.

  The fishing reel switching device according to a third aspect of the present invention is the device according to the second aspect, further comprising power supply voltage detecting means for detecting a power supply voltage supplied to the motor, wherein the detected power supply voltage is higher than the third voltage. The first and second duty ratios are corrected according to the detected power supply voltage. In this case, if the voltage is changed according to the duty ratio, the first and second voltages increase correspondingly when the power supply voltage increases. Therefore, the increase in the first and second voltages can be suppressed by correcting the increase in the power supply voltage by, for example, the ratio of the detected power supply voltage to the third voltage.

  A fishing reel switching device according to a fourth aspect of the present invention is the device according to any one of the first to third aspects, wherein the mechanism is provided between the spool and the handle, and is disconnected from a connected state where the handle and the spool are connected. It has a clutch mechanism that can be switched to the disconnected state, and the drive unit drives the spool in the yarn winding direction by forward rotation of the motor and drives the switching unit by reverse rotation, and the switching unit connects the clutch mechanism to the disconnected state. Switch to. In this case, the clutch mechanism can be switched from the disconnected state (clutch off state) to the connected state (clutch on state) by utilizing the reverse rotation of the motor that drives the spool in the yarn winding direction during forward rotation. The operation of returning the mechanism can be performed without adding a dedicated driver.

  The fishing reel switching device according to a fifth aspect of the present invention is the device according to the fourth aspect, wherein the drive unit is a mechanism mounting shaft as a drive component that is non-rotatably mounted on the output shaft of the motor, and a mechanism mounting shaft that cannot be rotated. A one-way clutch that has a claw wheel attached to the swing wheel, a swinging claw that is in contact with and away from the claw wheel and is biased toward the claw wheel, and is capable of prohibiting reverse rotation of the thread feeding direction of the motor; When the clutch mechanism is switched to the shut-off state by the pressing mechanism that is mounted side by side on the mechanism mounting shaft and rotates in conjunction with at least the reverse rotation of the motor and the operation of the switching unit, it contacts the claw member. When the claw member is separated from the claw wheel to move the motor to a reverse rotation permitted state and moved to a position where pressing by the pressing mechanism is possible. And a first clutch return mechanism having a linkage mechanism for a clutch mechanism to a connected state to via the switching unit. In this case, the clutch mechanism is brought into the clutch-off state by the switching unit when the device is inserted. When the clutch mechanism is in the clutch-off state, the interlocking mechanism of the first clutch return mechanism moves to a position where it can be pressed by the pressing mechanism, and the pawl member swings toward the reverse rotation permission position side against the biasing force by the interlocking mechanism. The motor is separated from the claw wheel and the motor can be reversely rotated. In addition, when the clutch is turned off, the spool is in a freely rotatable state, and the spool rotates in the line unwinding direction due to its own weight, and the fishing line is unwound. When the device reaches, for example, a shelf, the motor is reversely rotated to switch the clutch mechanism to the clutch-on state. When the motor is reversed, the pressing mechanism presses the interlocking mechanism and moves it to a position where pressing is impossible. At this time, the pressing mechanism collides with the interlocking mechanism and an impact acts on the pressing mechanism. This impact is transmitted to the mechanism mounting shaft, and a large torque is generated between the mechanism mounting shaft and the output shaft. The claw member moves to the reverse rotation prohibited position side by the urging force, and the clutch mechanism is switched to the clutch-on state via the switching unit. As a result, the spool is locked and fishing line feeding is stopped. Here, only when the interlocking mechanism is operated by reverse rotation of the motor to return to the clutch-on state, the first interlocking mechanism is pressed by the pressing mechanism to separate the pressing mechanism. There is no need to link. For this reason, when the clutch switching mechanism is manually operated to switch the clutch mechanism from the clutch-off state to the clutch-on state, the motor does not rotate, and a manual return operation is facilitated. Further, when the reverse rotation is performed, the pressing mechanism collides with the interlocking mechanism, and an impact acts on the pressing mechanism. This impact is transmitted to the mechanism mounting shaft, and torque is generated between the mechanism mounting shaft and the output shaft. However, since the voltage applied to the motor is gradually increased from the first voltage, the torque at the time of collision is reduced, and the mechanism mounting shaft is less likely to idle.

  The fishing reel switching device according to a sixth aspect of the present invention is the device according to the fifth aspect, further comprising a water depth calculating means for calculating a water depth of a device attached to a tip of a fishing line wound around the spool according to the rotation of the spool, The motor control unit reverses the motor according to the calculation result of the water depth calculation means. In this case, the device can be automatically arranged at the water depth according to the water depth.

  The fishing reel switching device according to a seventh aspect of the present invention is the device according to the sixth aspect, further comprising a water depth setting means capable of setting a predetermined water depth, wherein the motor control unit calculates the water depth and the water depth setting means calculated by the water depth calculation means. Reverse the motor in relation to the water depth set in. In this case, the device can be arranged at the position by setting the water depth such as the shelf position or the bottom position.

  The fishing reel switching device according to the invention 8, and the device according to any one of the inventions 5 to 7, wherein the one-way clutch moves the claw member to the reverse rotation permission position side until the position where the motor rotates forward in the yarn winding direction. And a claw member control mechanism for swinging. In this case, when the motor rotates in the forward direction, the claw member swings to a position where the claw wheel is swept away, so that the claw member for preventing reverse rotation does not vibrate during the forward rotation of the motor, and noise reduction can be achieved.

  According to the present invention, when the switching operation is performed using the motor, the voltage applied to the motor is gradually increased from the first voltage to the operable second voltage. It does not become a shocking torque load at the start, and the idling of the drive component fixed to the output shaft is less likely to occur.

[Counter configuration]
The counter 5 is provided for controlling the motor 4 while displaying the water depth of the device attached to the tip of the fishing line. The counter 5 includes a water depth display unit 98 composed of a liquid crystal display for displaying the water depth and shelf position of the device on the basis of two criteria, from the water surface and from the bottom, and a plurality of water depth display units 98 arranged around the water depth display unit 98. An operation key unit 99 including a switch is provided.

  As shown in FIG. 11, the operation key unit 99 includes a motor on / off power switch PW arranged vertically on the right side of the water depth display unit 98, a fishing mode setting switch LF for setting a mode related to fishing line, and a left side. And a water depth setting mode switch MD for setting the relationship between the yarn length and the water depth, and a position setting switch MS for setting the shelf position and the bottom position. .

Further, as shown in FIG. 12, a reel control unit 100 including a water depth display unit 98 and a microcomputer for controlling the motor 4 is provided inside the counter 5. The reel control unit 100 includes an operation key unit 99, an adjustment lever 101 that is swingably attached to the side cover 15 and adjusts the spool speed and fishing line tension, and the rotation speed and rotation direction of the spool 3. For example, a spool sensor 102 that detects two reed switches arranged side by side in the rotation direction, a power supply voltage sensor 106 that detects the voltage of a power supply connected to the electric reel, various notification buzzers 103, and a water depth display The unit 98, the PWM drive circuit 105 that drives the motor 4 with a duty ratio obtained by pulse width modulation (PWM), and other input / output units are connected. The reel control unit 100 controls the speed and torque of the motor 4 according to the operation amount of the adjustment lever 101. Further, the water depth of the device attached to the tip of the fishing line is calculated from the output of the spool sensor 102 and displayed on the water depth display unit 98. Furthermore, when the bottom position and the shelf position are set by operating the operation key unit 99, the calculated depth of water coincides with the set bottom position and the shelf position, and the device reaches the shelf position or the bottom position. Then, the motor 4 is reversely rotated to operate the clutch switching mechanism 8 via the first clutch return mechanism 12 to return the clutch mechanism 7 to the clutch-on state. Thereby, the device is arranged at that position.

  In the clutch return operation by the reverse rotation of the motor 4, as shown in FIG. 15, the reel control unit 100 gradually increases the duty ratio applied to the PWM drive circuit 105 from the first duty ratio D1 to the second duty ratio D2. To go. As a result, the voltage applied to the motor 4 gradually increases from the first voltage V1 to the second voltage V2. Here, the first voltage V1 is preferably in the range of 2 to less than 6 volts, for example. The second voltage V2 is a voltage at which a later-described pressing member 91 can press the advance / retreat member 96 by the reverse rotation of the motor 4, and is preferably in the range of 6 volts to 12 volts. The first duty ratio D1 needs to be changed according to the power supply voltage PV, but when the power supply voltage PV is 12 volts as in the case of using a lead battery, a range of 15% to less than 50% is preferable. The second duty ratio D2 is preferably in the range of 50% to 100%. As a result, the mechanism mounting shaft 75 that is fixed to the output shaft 30 during the reverse rotation of the motor 4 is less likely to idle. When the power supply voltage PV becomes 15 volts using a lithium battery, the duty ratios D1 and D2 are corrected to a value of 12/15, for example, so as to correct the increase in the power supply voltage PV. Thereby, even if a storage battery having a higher power supply voltage than a lead battery such as a lithium battery or a nickel metal hydride battery is used, the first and second voltages V1 and V2 applied to the motor 4 at the start of reverse rotation are less likely to fluctuate. The mechanism mounting shaft 75 that is fixed to the output shaft 30 at the time of reverse rotation of the motor 4 is further less likely to idle.

Between the second planetary gear 44 and the first carrier 45, a washer member 29 made of synthetic resin having a slippery property is mounted. When such a washer member 29 is mounted, the play of the first carrier 45 is reduced, and the noise of the planetary gear mechanism 40 can be reduced.

  The ratchet wheel 62 is non-rotatably mounted on the handle shaft 33 between the main gear 34 and the fixed frame 20. On the outer peripheral side of the ratchet wheel 62, serrated ratchet teeth 62a are formed.

  The ratchet pawl 71 is rotatably mounted on the side plate 17. The clamping member 72 is attached to the tip of the ratchet pawl 71 and can clamp the outer peripheral surface of the ratchet wheel 62. Due to the friction between the pinching member 72 and the ratchet wheel 62, the ratchet pawl 71 is separated to a position where it does not interfere with the ratchet teeth 62a when the ratchet wheel 62 rotates clockwise (yarn winding direction). The ratchet pawl 71 does not come into contact with each other at the time of rotation, and the noise can be reduced. On the other hand, when rotating counterclockwise (yarn feeding direction), the ratchet pawl 71 is pulled to a position where it interferes with the ratchet teeth 62a, and rotation in the yarn drawing direction is prohibited. In this electric reel, in addition to the first one-way clutch 9, a roller clutch 38 that instantaneously inhibits the reverse rotation of the handle shaft 33 is disposed between the side cover 15 and the handle shaft 33.

[Configuration of the second one-way clutch]
The second one-way clutch 10 is provided to prevent the planetary gear mechanism 40 from operating due to the reverse rotation of the motor 4 when the handle 1 is operated. As shown in FIGS. 6 and 7, the second one-way clutch 10 is a claw wheel 81 that is non-rotatably mounted on the second shaft portion 75 b of the mechanism mounting shaft 75, and a swing that makes contact with and separates from the claw wheel 81. A claw 82; a torsion coil spring 83 that urges the swing claw 82 toward the claw wheel; and a claw control mechanism 84 that controls the swing claw 82 when the motor 4 rotates forward in the yarn winding direction. ing.

  The claw wheel 81 has an oval hole 81b that engages with a chamfered portion 75c formed in the second shaft portion 75b of the mechanism mounting shaft 75 in a non-rotatable manner at the center. Moreover, it has two protrusion parts 81a formed in the outer periphery so as to protrude in the radial direction.

  The swinging claw 82 has a base end mounted on a swinging shaft 80 erected on the bulging portion 27 of the side plate 16 so as to be swingable. At the tip of the swinging claw 82, a claw portion 82a that protrudes toward the back side in FIG. 7 is formed. The claw portion 82a contacts the projection 81a of the claw wheel 81 to prevent reverse rotation of the claw wheel 81 (output shaft 30), and contacts the silent cam 85 (to be described later) of the claw control mechanism 84 to dodge the projection 81a. It is provided to swing the swinging claw 82 to the position.

  The swinging claw 82 swings between the reverse rotation prohibiting position where the first clutch return mechanism 11 can contact the protrusion 81a shown in FIG. 8 and the reverse rotation permission position shown in FIG. As described above, when the motor 4 is rotating forward, it swings slightly toward the reverse rotation permission position to the position where the projection 81a of the ratchet wheel 81 is dodged.

The claw control mechanism 84 is a mechanism for swinging the swing claw 82 to the reverse rotation permission position side to a position where the projection 81a of the claw wheel 81 is displaced when the motor 4 rotates forward. The claw control mechanism 84 is rotatably mounted on the first shaft portion 75a of the mechanism mounting shaft 75, and has a silent cam 85 having a protruding pressing portion 85a on the outer periphery for pressing the swinging claw 82 toward the reverse rotation prohibiting position. And a rotation restricting portion 86 for restricting the rotation range of the silent cam 85. The silent cam 85 is frictionally engaged with the first shaft portion 75 a and rotates in the same direction in conjunction with the rotation of the mechanism mounting shaft 75, and the rotation cam 86 rotates the silent cam 85. The mechanism mounting shaft 75 can rotate even if it is restricted. The rotation restricting portion 86 includes a locking piece 86a that is integrally formed so as to protrude in the radial direction from the silent cam 85, and a notch portion 86b that is formed on the cover member 28 and is locked with the locking piece 86a. Yes. Notch 86b is made form by cutting the arc-shaped side surface of the cover member 28 only swing range in an arc. A washer 87 is mounted between the silent cam 85 and the claw wheel 81.

[Configuration of first clutch return mechanism]
The first clutch return mechanism 11 returns the clutch mechanism 7 from the clutch-off state to the clutch-on state via the clutch switching mechanism 8 by the reverse rotation of the motor 4. As shown in FIGS. 4 to 7, the first clutch return mechanism 11 includes a pressing mechanism 88 that is mounted on the mechanism mounting shaft 75 side by side with the ratchet wheel 81 and rotates in conjunction with at least the reverse rotation of the motor 4, and the clutch switching mechanism 8. And an interlocking mechanism 89 that operates in conjunction with the.

  The pressing mechanism 88 is arranged on the third shaft portion 75 d of the mechanism mounting shaft 75 side by side with the claw wheel 81, and rotates in conjunction with the reverse rotation of the motor 4. The pressing mechanism 88 includes a roller clutch 90 mounted on the third shaft portion 75d and a pressing member 91 mounted non-rotatably on the outer peripheral side of the roller clutch 90. The roller clutch 90 is an outer ring idle type one-way clutch having an outer ring 90a and a plurality of rollers 90b housed in the outer ring 90a. The inner ring is integrated with the third shaft portion 75d of the mechanism mounting shaft 75. The roller clutch 90 transmits only the reverse rotation of the motor 4 to the pressing member 91. Here, the roller clutch 90 is attached to the pressing member 91 when the interlocking mechanism 89 is close to the pressing member 91 and the motor 4 is rotated forward in the clutch-off state. This is to prevent a problem from occurring even if contact is made. When the motor 4 rotates in the reverse direction, the rotation of the pressing member 91 is transmitted via the roller clutch 90 and rotates. The pressing member 91 includes, for example, three cylindrical portions 91a that are non-rotatably mounted on the outer ring 90a of the roller clutch 90, and are formed on the outer peripheral side of the cylindrical portion 91a in the radial direction and spaced apart in the circumferential direction. And a protrusion 91b. The protrusion 91 a is a protrusion that can press the interlock mechanism 89.

  The interlocking mechanism 89 operates in conjunction with the operation of the clutch switching mechanism 8. When the clutch mechanism 7 is switched to the clutch-off state by the clutch switching mechanism 8, the interlocking mechanism 89 comes into contact with the swinging claw 82 and moves the swinging claw 82 to the claw wheel. It moves away from 81 and moves to a release position where pressing by the pressing mechanism 88 is possible. As a result, the motor 4 enters the reverse rotation permission state. Further, when the motor 4 rotates in the reverse state, the interlocking mechanism 89 is pressed by the pressing mechanism 88 and moves to a locking position where pressing is impossible. When moved to the locking position, the swinging claw 82 moves away from the swinging claw 82 and is locked to the claw wheel 81.

  The interlock mechanism 89 passes through the side plates 16 and 17, has one end rotatably mounted on the side plates 16 and 17, and a connection shaft 93 disposed outside the fixed frame 20, and cannot be rotated at both ends of the connection shaft 93. The first and second lever members 94 and 95 are attached, and the advance / retreat member 96 is connected to the tip of the second lever member 95.

The connecting shaft 93 is a shaft member that is rotatably attached to the side plates 16 and 17 and has one end protruding outward from the fixed frame 20 and the other end protruding outward from the side plate 16. Chamfered portions 93a and 93b that are parallel to each other for mounting the first and second lever members 94 and 95 in a non-rotatable manner are formed at the protruding ends of the connecting shaft 93. The first lever member 94 has a base end Is a member that is non-rotatably attached to the chamfered portion 93a of the connecting shaft 93 on the fixed frame 20 side. The distal end of the first lever member 94 is locked to the distal end of the third projecting portion 56c of the clutch cam 51 constituting the clutch switching mechanism 8 so as to be rotatable and movable for a predetermined distance. Thereby, the rotation of the clutch cam 51 is transmitted to the first clutch return mechanism 11, and the return operation of the first clutch return mechanism 11 is transmitted to the clutch cam 51 and the clutch switching mechanism 8 can be operated.

  The second lever member 95 is a member whose base end is non-rotatably attached to the chamfered portion 93 b of the connecting shaft 93 on the side plate 16 side. The distal end of the second lever member 95 is locked to the proximal end of the advance / retreat member 96 so as to be rotatable and movable for a predetermined distance. As a result, the advance / retreat member 96 advances and retracts in conjunction with the operation of the clutch switching mechanism 8, and the clutch changeover mechanism 8 operates in the clutch-off direction by the backward operation of the advance / retreat member 96.

  The advancing / retracting member 96 is guided by a pair of guide portions 27 a and 27 b formed on the bulging portion 27 so as to be linearly movable toward the swinging claw 82 and the pressing member 88. The advancing / retracting member 96 is a plate-like member in which the second lever member 95 is connected to the base end so as to be rotatable and movable within a predetermined range. The advancing / retracting member 96 is understood by the swinging claw 82 and extends so that it can contact the lower surface of the swinging claw 82, and a second contact member 96b bent from the base of the first contact portion 96a toward the pressing member 91. A contact portion 96b is provided at the tip. The advancing / retreating member 96 has a release position shown in FIG. 9 in which the second contact portion 96b can be pressed by the pressing member 91, and the first contact portion 96a presses the swinging claw 82 to swing to the reverse rotation permission position, The one contact portion 96a is movable away from the swinging claw 82 and to the locking position shown in FIG. 8 where the pressing by the pressing member 91 is impossible. Specifically, when the clutch switching mechanism 8 moves from the clutch-off position to the clutch-on position side, the first and second lever members 94 and 95 swing and the advance / retreat member 96 advances to the release position, and the motor 4 When it is pressed by the pressing member 91 by reverse rotation, it moves backward to the locking position. As a result, the clutch cam 51 rotates in the clutch-on direction via the second and first lever members 95, 94, the clutch operation lever 50 returns to the clutch-on position, and the clutch mechanism 7 enters the clutch-on state.

[Configuration of second clutch return mechanism]
The second clutch return mechanism 12 returns the clutch cam 51 disposed at the clutch-off position to the clutch-on position in accordance with the rotation of the handle 1 in the yarn winding direction, and returns the clutch mechanism 7 to the clutch-on state. The cam 51 returns the clutch operation lever 50 from the clutch-off position to the clutch-on position. The second clutch return mechanism 12 urges the engaging member 61, the ratchet wheel 62 having ratchet teeth 62a formed on the outer periphery thereof, and the engaging member 61 to be moved toward the engaging position and the non-engaging position. And a second toggle spring 66. As described above, the engaging member 61 is swingably supported by the second projecting portion 56b of the clutch cam 51, and has a first protrusion 61a that engages with the ratchet teeth 62a of the ratchet wheel 62, and a first protrusion 61a. The first protrusion 61a has a second protrusion 61b extending to the left in FIG.

  The first protrusion 61a is bent toward the outside of the ratchet wheel 62, and the second protrusion 61b is bent to the opposite side to the fixed frame 20 side. The fixed frame 20 is formed with a deformed trapezoidal guide protrusion 20a that engages with the second protrusion 61b. The guide protrusion 20a is provided to control the swinging direction of the engaging member 61 by engaging with the second protrusion 61b.

  When the engaging member 61 is disposed at the engaging position, the first protrusion 61a is located on the inner peripheral side from the outer periphery of the ratchet wheel 62 and can be locked to the ratchet teeth 62a, and is disposed at the non-engaging position. Then, the first protrusion 61 a is located at a position slightly separated from the outer periphery of the ratchet wheel 62. The engaging member 61 is disposed in front of and above the axis of the ratchet wheel 62. For this reason, the space on the rear side of the ratchet wheel 62 can be small as compared with the conventional example disposed behind the ratchet wheel 62. The first protrusion 61a of the engaging member 61 is pulled by the ratchet teeth 62a and rotates from the engaging position shown in FIG. 5 to the non-engaging position shown in FIG.

  Since the level wind mechanism and the casting control mechanism have the same configuration as a conventionally known electric reel, description thereof is omitted.

[Clutch switching operation]
Next, the clutch switching operation of the electric reel will be described.

  In a normal state, the clutch yoke 52 is pushed inward in the pinion gear axial direction by the coil spring 54, whereby the pinion gear 35 is moved to the clutch-on position. In this state, the engagement concave portion 35a of the pinion gear 35 and the engagement convex portion 46a of the second carrier 46 are engaged with each other and the clutch is on.

  When putting the device, the clutch operation lever 50 is swung to the clutch-off position shown in FIG. When the clutch operating lever 50 swings from the clutch-on position shown in FIG. 4 to the clutch-off position shown in FIG. 5, the clutch cam 51 rotates counterclockwise in FIG. As a result, the clutch yoke 52 rides on the cam protrusions 57a and 57b of the clutch cam 51, and the clutch yoke 52 is moved outward in the pinion gear axial direction. Since the clutch yoke 52 is engaged with the constricted portion 35c of the pinion gear 35, the pinion gear 35 is also moved in the same direction as the clutch yoke 52 moves outward. In this state, the engagement concave portion 35a of the pinion gear 35 and the engagement convex portion 46a of the second carrier 46 are disengaged, and the clutch is turned off. In this clutch-off state, the spool 3 is in a freely rotatable state. As a result, the fishing line is unwound from the spool 3 due to the weight of the device.

In the yarn feed mode, for example, when the feed amount exceeds a predetermined amount (for example, the water depth display of the device is 6 m) or the rotation speed of the spool 3 exceeds the predetermined speed, the motor 4 rotates in the yarn winding direction. Since the second carrier 46 rotates in the clutch-off state, the planetary gear mechanism 40 does not decelerate even when the motor 4 is rotated forward, but the friction between the planetary gear mechanism 40 and the spool 3 is reduced, and the spool 3 is free. Rotates in the yarn unwinding direction at a higher speed than the rotating state.

  Further, when the clutch cam 51 rotates to the clutch-off position, the engaging member 61 of the second clutch return mechanism 12 is guided by the guide protrusion 20a and swings in the clockwise direction. The spring 66 biases the ratchet wheel 62 inward. As a result, the engaging member 61 is disposed at an engaging position where the engaging member 61 is locked to the ratchet teeth 62a.

  Further, when the clutch cam 51 rotates to the clutch-off position, the advance / retreat member 96 of the interlocking mechanism 89 of the first clutch return mechanism 11 advances from the locking position shown in FIG. 8 to the release position shown in FIG. When the advance / retreat member 96 advances to the release position, the first contact portion 96a comes into contact with the swing claw 82 of the second one-way clutch 10, and the swing claw 82 is moved from the reverse rotation prohibition position shown in FIG. 8 to the reverse rotation permission position shown in FIG. Rocks. As a result, the motor 4 becomes in a state capable of reverse rotation. When the advance / retreat member 96 advances to the release position, the second contact portion 96a is disposed at a position where the projection 91b of the pressing member 91 can be pressed.

When the device is arranged on a predetermined shelf, the motor 4 is rotated in the reverse direction, the handle 1 is rotated in the yarn winding direction, or the clutch operating lever 50 is swung to the clutch-on position to stop the thread feeding of the spool 3. . When the automatic shelf stop mode, the yarn feeding spool 3 is stopped automatically to rack position by the reverse rotation of the motor 4.

When the motor 4 is reversely rotated, the first clutch return mechanism 11 returns to the clutch-on state. When the motor 4 is reversed, as shown in FIG. 9, the pressing member 91 is reversed (clockwise rotation in FIG. 9), and any one of the three protrusions 91 b presses the second contact portion 96 b of the advance / retreat member 96. Then, the advance / retreat member 96 is retracted from the release position toward the locking position. Then, the clutch cam 51 connected to the first lever member 94 via the second lever member 95 and the connecting shaft 93 rotates clockwise in FIG. At this time, when the dead point of the first toggle spring 65 is exceeded, the clutch cam 51 returns to the clutch-on position, whereby the advance / retreat member 96 also returns to the locking position. When the clutch cam 51 rotates clockwise toward the clutch-on position, the clutch yoke 52 riding on the cam protrusions 57a and 57b of the clutch cam 51 descends from the cam protrusions 57a and 57b and the coil spring 54 is attached. It moves inward in the spool axial direction by the force. As a result, the pinion gear 35 also moves inward in the spool axial direction and is disposed at the clutch-on position. When the clutch cam 51 rotates clockwise in FIG. 5, the clutch operation lever 50 locked to the first protrusion 56a also swings to the clutch-on position. Thereby, the clutch mechanism 7 can be changed from the clutch-off state to the clutch-on state without operating the clutch operation lever 50. Further, when the reciprocating member 96 returns to the locking position location, the swing claw 82 which is biased by a coil spring 83 torsion returns to reverse inhibition position, the first one-way clutch 9 becomes reverse-rotation prohibition state, the motor Inversion of 4 is prohibited.

  During the reverse rotation of the motor 4, the pressing member 91 mounted on the mechanism mounting shaft 75 via the roller clutch 90 collides with the second contact portion 96 b of the advance / retreat member 96 and presses it. At this time, an impact acts on the pressing member 91, and the torque caused thereby acts on the serration 30 a of the fixed portion between the mechanism mounting shaft 75 and the output shaft 30. Since this portion has a small diameter, the force in the tangential direction is increased, and if the power supply voltage is applied to the motor 4 as it is, there is a possibility that the portion may idle. Therefore, in the present embodiment, the motor 4 is controlled at a duty ratio that gradually increases from the first duty ratio D1 to the second duty ratio D2 shown in FIG. The member 96 is gradually raised to a voltage that can be pressed. As a result, the torque when the pressing member 91 collides with the advancing / retracting member 96 at the start of reverse rotation is reduced, and the drive components mounted on the output shaft 30 such as the mechanism mounting shaft 75 mounted with the pressing member 91 are less likely to idle. .

  When the handle 1 is rotated in the yarn winding direction, the second clutch return mechanism 12 returns to the clutch-on state. When the handle 1 is rotated in the yarn winding direction, the handle shaft 33 rotates clockwise in FIG. Accordingly, the ratchet wheel 62 fixed to the handle shaft 33 so as not to rotate is also rotated clockwise. When the ratchet wheel 62 rotates clockwise, the first protrusion 61a of the engaging member is caught by the ratchet teeth 62a, and the engaging member 61 is pulled.

  When the engaging member 61 is pulled, the engaging member 61 is guided by the guide protrusion 20 a and swings counterclockwise. When the engaging member 61 exceeds the dead point of the second toggle spring 66, the engaging member 61 is moved to the ratchet wheel 62. Is energized outward. Then, the engaging member 61 swings outward toward the non-engaging position where the ratchet wheel 62 is not engaged.

  When the engaging member 61 is pulled, the clutch cam 51 connected to the engaging member 61 rotates clockwise in FIG. 5 and returns to the clutch-on position as described above. Thereby, also here, the clutch mechanism 7 can be changed from the clutch-off state to the clutch-on state without operating the clutch operation lever 50.

  The engagement member 61 of the second clutch return mechanism 12 is disposed on the upper front side of the handle shaft 33. The upper front position of the handle shaft 33 is an empty space when the counter 5 is provided. When the engaging member 61 is provided in this vacant space, the bulge of the reel main body can be reduced as compared with a configuration in which the engaging member is disposed behind and below the handle shaft as in the prior art.

  In the first and second clutch return mechanisms 11 and 12, even if the clutch operating lever 50 is operated from the clutch-off position to the clutch-on position, the advancing / retracting member 96 returns to the locking position and the engaging member 61 is not engaged. It goes without saying that it returns to the matching position.

  When the fish is caught in the clutch in the clutch-on state, the spool 3 is rotated in the line winding direction by the rotation drive of the handle 1 or the motor 4, and the fishing line is wound up.

  During manual winding, the rotation of the handle 1 in the yarn winding direction (clockwise rotation in FIG. 4) is accelerated and transmitted to the spool 3 via the handle shaft 33, the main gear 34, the pinion gear 35, and the planetary gear mechanism 40. Is done. At this time, the reverse rotation of the motor 4 (counterclockwise rotation when viewed from the right side of FIG. 3) is prohibited by the second one-way clutch 10. For this reason, the first sun gear 41 of the planetary gear mechanism 40 does not reverse, and the second planetary gear 44 and the first carrier rotate from the second carrier 46 that rotates in the yarn winding direction (clockwise rotation as viewed from the right side in FIG. 3). The rotation is transmitted to the internal gear 3d via the first planetary gear 43, and the spool 3 is driven to increase in the yarn winding direction.

  When the motor is driven, the rotation of the motor 4 that normally rotates (clockwise rotation as viewed from the right side in FIG. 3) is transmitted to the spool 3 via the planetary gear mechanism 40. At this time, the rotation of the handle shaft 33 in the yarn feeding direction (counterclockwise rotation when viewed from the right side in FIG. 3) is prohibited by the first one-way clutch 9, so that the second carrier 46 is reversely rotated (as viewed from the right side in FIG. 3). (Clockwise rotation) is prohibited. For this reason, the rotation of the decelerated second sun gear 42 is transmitted to the internal gear 3d via the second planetary gear 44, and the spool 3 is driven to decelerate.

  As shown in FIG. 10, when the motor 4 rotates in the forward direction (counterclockwise rotation in FIG. 10) in the clutch-on state, the silent cam 85 of the pawl control mechanism 84 rotates in the same direction, and the rotation restricting portion 86. As a result, the claw portion 82a of the swinging claw 82 stops at the position where the pressing portion 85a presses. At this time, since the silent cam 85 is merely frictionally engaged with the mechanism mounting shaft 75, the motor 4 rotates as it is. As a result, the swinging claw 82 is pressed by the pressing portion 85a and swings to the reverse rotation permission position side to the position where the projection 81a of the claw wheel 81 is displaced, so that the claw wheel 81 does not contact the swinging claw 82. For this reason, when the motor 4 rotates in the forward direction, the click sound due to the swinging claw 82 of the first one-way clutch 9 repeatedly contacting the claw wheel 81 is not generated, and the noise can be reduced.

  When the motor 4 rotates in the reverse direction, the silent cam 85 rotates in the same direction, and as shown in FIG. 8, the rotation restricting portion 86 stops at a position where the pressing portion 85a is disengaged from the claw portion 82a, and the swinging claw 82 is twisted. The coil spring 83 is biased to return to the reverse rotation prohibited position.

  Further, when the motor 4 rotates in the forward direction in the clutch-off state as in the yarn feed mode, the silent cam 85 can also rotate in the same direction to achieve noise reduction. At this time, since the pressing member 91 is mounted on the mechanism mounting shaft 75 via the roller clutch 90 that transmits only the reverse rotation of the motor 4, the rotation of the mechanism mounting shaft 75 is not transmitted to the pressing member 91. For this reason, even if the advancing / retracting member 96 is disposed so as to be in contact with the pressing member 91 in the clutch-off state, the pressing member 91 does not press the advancing / retreating member 96, and there is no problem due to this.

[Operation of reel control unit]
Next, specific control processing performed by the reel control unit 100 will be described with reference to the control flowcharts of FIG.

  When an external power source is connected to the electric reel, initial setting is performed in step S1 of FIG. In this initial setting, the count value of the spool rotation number is reset, various variables and flags are reset, and the gear position is set to the first speed. In step S2, the power supply voltage PV detected by the power supply voltage sensor 106 is captured. In step S3, it is determined whether or not the power supply voltage PV is higher than 12 volts, that is, whether or not a type of storage battery having a higher power supply voltage different from the lead storage battery is connected to the reel. When a battery of a type having a high power supply voltage PV (for example, a lithium battery or a nickel metal hydride battery) is connected, the process proceeds from step S3 to step S4, and the power supply voltage in which the duty ratios D1 and D2 at the time of motor reverse rotation are detected. Correct according to PV. Specifically, the basic first and second duty ratios D1 and D2 multiplied by a value obtained by dividing 12 by the power supply voltage PV (12 / PV) are used as new first and second duty ratios D1 and D2. To do. Thereby, even if the power supply voltage PV fluctuates, the first and second voltages V1 and V2 applied to the motor 4 at the time of reverse rotation are less likely to fluctuate. In this embodiment, the power supply voltage is determined only once after the initial setting for connecting the power supply. However, the determination may be performed a plurality of times after the power supply is connected.

  In step S5, display processing is performed. In the display process, various display processes such as water depth display are performed. In step S6, it is determined whether any switch of the operation key unit 99 or the adjustment lever 101 is operated. In step S7, it is determined whether or not the spool 3 is rotating. This determination is made based on the output of the spool sensor 102. In step S8, it is determined whether or not the water depth LX calculated from the output of the spool sensor 102 is 6 m or more. In step S9, it is determined whether any other command or input has been made.

  When key input is performed by the operation key unit 99 or the adjustment lever 101, the process proceeds from step S6 to step S10, and key input processing is executed. In this key input process, when the power switch SW is operated, the forward rotation of the motor 4 is turned on / off. When the adjustment lever 101 is operated, the motor 4 is increased or decreased or the torque of the motor 4 is increased or decreased according to the accuracy of the swing. Further, when the fishing mode setting switch LF is operated, a line feed mode, a shelf stop mode, and the like are set.

  When the rotation of the spool 3 is detected, the process proceeds from step S7 to step S11. In step S11, each operation mode process described later is executed. When the water depth LX is 6 m or more, the process proceeds from step S8 to step S12. In step S12, it is determined whether or not the device stop time at the water depth LX is 6 seconds or more. In the case of 6 seconds or more, it is considered that the device has stopped the shelf, so the process proceeds to step S13 and the water depth LX is set at the shelf position M. If any other command or input is made, the process proceeds from step S9 to step S14 to execute other processes.

  In each operation mode process in step S11, it is determined in step S21 in FIG. 14 whether or not the rotation direction of the spool 3 is the yarn feeding direction. This determination is made based on which reed switch of the spool sensor 102 has issued a pulse first. When the rotation direction of the spool 3 is determined to be the yarn feeding direction, the process proceeds from step S21 to step S22. In step S22, every time the count value of the pulse output from the spool sensor 102 decreases, data indicating the relationship between the water depth and the count value stored in the reel control unit 100 is read based on the count value and the water depth LX is calculated. . This water depth is displayed in the display process of step S2.

  In step S23, it is determined whether or not the yarn feeding mode is set. In step S24, it is determined whether or not the shelf stop mode. In step S25, it is determined whether the mode is another mode. If it is not in another mode, each operation mode process is terminated and the process returns to the main routine.

  In the yarn feed mode, the process proceeds from step S23 to step S26. In step S26, it is determined whether the water depth LX is 6 m or more. In the line feed mode, the motor 4 is not normally rotated from the beginning, but waits for the fishing line to be fed to a water depth at which it can be determined that the fishing line has been reliably fed. When the water depth LX is 6 m or more, the process proceeds to step S27 and the motor 4 is rotated forward. As a result, as described above, the friction between the planetary gear mechanism 40 and the spool 3 is reduced, and the spool 3 rotates in the yarn unwinding direction at a higher speed. When the water depth LX is less than 6 m, step S27 is skipped.

  The process proceeds from step S24 for determining the shelf stop mode to step S28. In step S28, it is determined whether the obtained water depth LX matches the shelf position M, that is, whether the device has reached the shelf. The shelf position is set by pressing the position setting switch MS when the device reaches the shelf, in addition to the above-described automatic setting by stopping for a predetermined time or more. When the device reaches the shelf position, the process proceeds from step S28 to step S29. In step S29, the buzzer 103 is sounded to notify that the device is on the shelf. In step S30, the motor 4 is reversely rotated for a predetermined time. At this time, as shown in FIG. 15, the duty ratio is gradually increased from the first duty ratio D1 to the second duty ratio D2, and the voltage applied to the motor 4 is gradually increased. As a result, excessive torque due to impact is less likely to act on the mechanism mounting shaft 75, and the mechanism mounting shaft 75 mounted on the output shaft 30 of the motor 4 is less likely to idle. Due to the reverse rotation of the motor 4, the clutch mechanism 7 is returned to the clutch-on state by the first clutch return mechanism 11 via the clutch switching mechanism 8 in the above-described operation. As a result, the rotation of the spool in the yarn unwinding direction stops. If the water depth LX has not reached the shelf position M, steps S29 and S30 are skipped. If it is determined that the mode is another mode, the process proceeds from step S25 to step S31, and the set other mode process is executed.

  When the rotation of the spool 3 is determined to be the yarn winding direction, the process proceeds from step S21 to step S32. In step S32, every time the count value of the spool sensor 102 increases, the data stored in the reel control unit 100 is read and the water depth LX is calculated. This water depth is displayed in the display process of step S2. In step S33, it is determined whether or not the water depth matches the ship edge stop position. If it has not been wound up to the ship edge stop position, it returns to the main routine. When the ship edge stop position is reached, the process proceeds from step S33 to step S34. In step S34, the buzzer 103 is sounded to notify that the device is on the shore. In step S35, the motor 4 is turned off. As a result, the fish is arranged at a position where it can be easily taken when the fish is caught. This ship edge stop position is set when, for example, the water depth is less than 6 m and the spool 3 is stopped for a predetermined time or more.

  Here, only when the interlocking mechanism 89 is operated by reverse rotation of the motor 4 to return to the clutch-on state, the interlocking mechanism 89 is pressed by the pressing mechanism 88 to separate the pressing mechanism 88. It is not necessary to always link the mechanism 89. For this reason, when the clutch switching mechanism 8 is manually operated to switch the clutch mechanism 7 from the clutch-off state to the clutch-on state, the motor 4 does not rotate, and a manual return operation is facilitated.

  When the motor 4 rotates forward, the claw control mechanism 84 swings the swing claw 82 to a position where the claw wheel 81 is displaced, so that the swing claw 82 for preventing reverse rotation does not vibrate when the motor 4 rotates forward. Silence can be achieved.

  Furthermore, since the roller clutch 90 is interposed between the pressing member 91 of the pressing mechanism 88 and the output shaft 30 so that the forward rotation of the output shaft 30 is not transmitted to the pressing member 91, in the yarn feeding mode, Even if the pressing member 91 comes into contact with the interlocking mechanism 89, it is not pressed, and the yarn feeding mode can be carried out smoothly.

Furthermore, since the voltage applied to the motor 4 is gradually increased from the first voltage V1 to the second voltage V2 during the clutch return operation due to the reverse rotation of the motor 4, it is shocking from the start of rotation to the start of the switching operation. An excessive force is not applied to the mechanism mounting shaft 75 fixed to the output shaft 30 of the motor 4 without being a torque load, and the idling of the mechanism mounting shaft 75 can be prevented [another embodiment].
(A) In the above embodiment, when the spool rotating motor 4 is reversely rotated, the voltage is gradually increased from the first voltage V1 to the second voltage V2. However, the present invention can also be applied to motor control even when a motor is used as a driving body and the one-way clutch or clutch mechanism of a fishing reel is switched via, for example, a speed reducer and a rotating cam mechanism.

  (B) In the above embodiment, the motor 4 is disposed in the spool 3, but the present invention can also be applied to an electric reel switching device in which the motor 4 is disposed outside the spool 3. In this case as well, the idling of the drive component mounted on the output shaft of the motor can be prevented as in the above embodiment.

  (C) Although the electric reel has been described as an example in the embodiment, the present invention can be applied to a manually wound counter reel that uses a motor as a driving body.

  (D) In the above embodiment, the claw wheel 81 and the pressing member 91 are mounted on the output shaft 30 via the mechanism mounting shaft 75 in order to facilitate mounting, but may be mounted directly on the output shaft. In this case, a driving member corresponds to a pressing member or a roller clutch.
