The idea is to detect the tension of the fishing line by detecting the torque acting on the spool when pulled.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional device, since the magnetostrictive material is mounted on the spool shaft by bonding, the mounting operation is difficult, and the productivity is poor. Further, the magnetostrictive material attached to the spool shaft by bonding may be peeled off and has poor reliability. Furthermore, due to the adhesive layer, the torque applied to the spool does not properly reach the magnetostrictive material, and the accuracy of detection is low.
[0004]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fishing reel that can detect the tension of a fishing line with good manufacturability and reliability and with high detection accuracy.

The hit judging means judges the hit of the fish by comparing the amount of change in the magnitude of the detection data based on the detection result of the torque sensor per predetermined time with the recorded data of the actual fishing results so far.(The invention of claim 2).
[0008]
According to this configuration, the torque acting on the rotor when the fishing line is pulled is detected by the magnetostrictive torque sensor, whereby the tension of the fishing line is detected. In this case, the magnetostrictive material of the torque sensor is provided on the torque detecting shaft by plating, as described above, whereby the manufacturability is better than that provided by bonding, there is no fear of peeling, and the reliability can be improved.

Further, even in this case, the hit of the fish can be more accurately determined based on the result of comparison with the recorded data of the actual fishing results.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present inventionFirst basic configurationThis will be described with reference to FIGS.
First, FIG. 1 shows an overall configuration of a fishing reel. A spool 1 is mounted around a spool shaft 2 so as to be rotatable together with the spool shaft 2. One end of the fishing line 3 is attached and wound.
[0019]
A driven gear 4 is attached to one end of the spool shaft 2 on the right side in the figure, and a driven gear 5 is meshed with the driven gear 4. A handle 8 having a knob 7 is attached to a rotary shaft 6 of the drive gear 5. The handle 8 is rotated clockwise by a fisherman, so that the driven gear 4 The rotational force is transmitted to the spool 1, whereby the spool 1 is rotated via the spool shaft 2, and the fishing line 3 is wound around the spool 1.
[0020]
In this case, as an example, the clutch 9 is provided for the drive gear 5. The clutch 9 is a one-way clutch. The drive gear 5 and, consequently, the spool 1 are wound around the fishing line 3 (rotational force is transmitted in the direction of arrow A, and the fishing line 3 is restrained in the opposite direction). State (free to rotate in the direction opposite to arrow A).
[0021]
In this case, between the clutch 9 and the portion 2a of the spool shaft 2 supporting the spool 1, a part of the spool shaft 2 (a portion projecting from the spool 1 and from the driven gear 4) (A protruding portion) is located, and a magnetostrictive torque sensor 11 is provided between the torque detecting shaft 10 and the outer periphery thereof.
[0022]
As shown in detail in FIG. 2, the torque sensor 11 includes a magnetostrictive material 12 provided on an outer peripheral portion of the torque detecting shaft 10 and a coil 13 provided on an outer periphery of the magnetostrictive material 12. I have. The magnetostrictive material 12 is provided on the outer periphery of the torque detecting shaft 10 by plating, and for example, an alloy of nickel and iron is used as the material.
[0023]
More specifically, on the outer peripheral portion of the torque detecting shaft 10, a number of rectangular concave portions 14a are formed at a predetermined inclination angle with respect to the axial direction of the torque detecting shaft 10, and the convex portions 14b are formed between the concave portions 14a. The magnetostrictive material 12 is provided on the surface of the uneven portion 14 by plating (see FIG. 3). The formation of the concave and convex portions 14, particularly the formation of the concave portions 14a, is performed by a manufacturing method such as rolling or etching.
[0024]
Here, in a state where the rotation of the spool 1 in the direction in which the fishing line 3 is extended (the direction of the arrow B in FIG. 2) is restricted by the clutch 9, when the fishing line 3 is pulled in the extension direction, the spool 1 , A stress σ mainly in a tensile direction is generated at an outer peripheral portion of the torque detection shaft 10 to which the driven gear 4 side is fixed at a predetermined inclination angle with respect to the axial direction of the torque detection shaft 10.
[0025]
The concavo-convex portion 14 is formed on the spool shaft 2 so as to have a direction substantially parallel to the direction of the above-described main stress σ, thereby providing a magnetostrictive material plated on the surface of the concavo-convex portion 14. 12 also has a directionality substantially parallel to the direction of the main stress σ.
[0026]
In this case, the inclination angle of the concavo-convex portion 14 and, consequently, the inclination angle of the magnetostrictive material 12 are set to 45 ° as a preferable angle in this case. In addition, the single coil 13 is provided so as to surround the magnetostrictive material 12 at an interval of, for example, 0.5 [mm] around the magnetostrictive material 12 provided as described above.
[0027]
Next, FIG. 4 shows a detection circuit including the coil 13 of the torque sensor 11. A bridge circuit 18 is formed by the coil 13, the variable resistor 15, and the fixed resistors 16, 17, and an input terminal of the bridge circuit 18 is provided. Is connected between a signal generator 19 for generating a high-frequency square wave signal of, for example, about 10 [kHz] and ground.
[0028]
On the other hand, a differential amplifier 20 is connected between the output terminals of the bridge circuit 18, and the output terminal of the differential amplifier 20 is connected to a detection output terminal 22 via a diode 21 having the illustrated polarity. A smoothing capacitor 23 is connected between the detection output terminal 22 and the ground. In FIG. 4, V1 and V2 indicate both output voltages of the bridge circuit 18, V3 indicates an output voltage of the differential amplifier 20, and Vout indicates an output voltage of the detection output terminal 22.
[0029]
Next, the operation of the above configuration will be described.
In a state in which the fish waits for the bait, the rotation of the spool 1 in the fishing line unwinding direction after the fishing line 2 is unwound by the clutch 9 is restricted so that only the rotation in the winding direction of the fishing line 2 can be performed.
[0030]
In this state, a high-frequency square wave signal of, for example, about 10 [kHz] is applied from the signal generator 19 to the bridge circuit 18 of the detection circuit. As a result, the output voltage V1 of the bridge circuit 18 becomes as shown in FIG.
The high-frequency square wave signal of, for example, about 10 [kHz] applied from the signal generator 19 is divided by the coil 13 and the fixed resistor 17 of the bridge circuit 18 and is affected by the inductance of the coil 13. As a result, the output voltage V2 of the bridge circuit 18 is normally as shown by a solid line in FIG.
[0031]
Then, when they are input to the differential amplifier 20 and differentially output, the output voltage V3 of the differential amplifier 20 is always as shown by a solid line in FIG.
Further, as a result of the output voltage V3 being rectified by the diode 21 and smoothed by the capacitor 23, the output voltage Vout of the detection output terminal 22 is always as shown by the solid line in FIG.
[0032]
In such a situation, when the fish eats the bait and pulls the fishing line 3, tension is generated in the fishing line 3, and a corresponding torque τ is applied from the spool 1 to the spool shaft 2. At the same time, a stress σ mainly in the tensile direction is generated at a predetermined inclination angle with respect to the axial direction of the torque detection shaft 10 on the outer peripheral portion of the torque detection shaft 10. For this reason, a tensile stress is applied to the magnetostrictive material 12 provided on the outer peripheral portion of the torque detection shaft 10 with a direction in the direction, thereby increasing the magnetic permeability of the magnetostrictive material 12. Therefore, the inductance of the coil 13 also increases.
[0033]
Then, in the detection circuit, the output voltage V2 of the bridge circuit 18 is more affected by the inductance of the coil 13 than the above, and the rising and falling become slow as shown by the broken line in FIG. Correspondingly, the output voltage V3 of the differential amplifier 20 also has the maximum values of rising and falling as shown by the broken lines in FIG. 5C. Therefore, the output voltage Vout of the detection output terminal 22 increases its output as shown by the broken line in FIG.
Thus, by detecting the torque acting on the spool 1 when the fishing line 3 is pulled, the tension of the fishing line 3 is detected.
[0034]
In this case, the magnetostrictive material 12 of the torque sensor 11 is provided on the torque detection shaft 10 by plating, and there is no difficulty in mounting work unlike the one provided by bonding, so that the manufacturability can be improved. . Further, the magnetostrictive material 12 provided on the torque detecting shaft 10 by plating does not have to worry about peeling, unlike the material provided by adhesion, and can improve the reliability. Further, since the magnetostrictive material 12 provided on the torque detecting shaft 10 by plating does not have an adhesive layer, the torque (main stress σ in the tensile direction) applied to the spool 1 is correctly applied to the magnetostrictive material 12 and thus acts on the spool 1. The detection accuracy of the detected torque, and thus the detection accuracy of the tension of the fishing line 3 can be increased.
[0035]
In addition, the magnetostrictive material 12 may be plated in a strip shape on the smooth surface of the torque detection shaft 10 at the above-described predetermined inclination angle, however, in the above configuration, the outer periphery of the torque detection shaft 10 The irregularities 14 are formed at the predetermined inclination angle (direction substantially parallel to the direction of the main stress in the pulling direction acting on the torque detection shaft 10 when the torque in the fishing line payout direction is applied to the spool 1), The magnetostrictive material 12 is provided on the surface of the uneven portion 14 by plating.
[0036]
Thereby, the magnetostrictive material 12 which needs to have the above-mentioned directionality can be provided only by plating the surface of the uneven portion 14 formed on the outer peripheral portion of the torque detecting shaft 10, thereby further improving the manufacturability. be able to.
In addition, the number of coils 13 is one, and the torque sensor 11 detects torque based on a change in inductance of the coil 12. Accordingly, the torque sensor 11 can be made compact, and can be made suitable for a small and lightweight fishing reel.
[0037]
6 to 16 illustrate the present invention.Other configurations including embodimentsIn each of the drawings, the same parts as those in the above basic configuration are denoted by the same reference numerals, description thereof will be omitted, and only different parts will be described.
[0038]
[SecondBasic configuration of]
Shown in FIGS. 6 to 8Second basic configurationIn FIG. 7, first, as shown in FIG. 6, the coil 31 and the coil 32 are provided twice around the outer periphery of the magnetostrictive material 12 to constitute a torque sensor 33, and as shown in FIG. A signal generator 34 for generating a high-frequency sine wave signal of, for example, about 10 [kHz] is connected to 31. An amplifier 35 is connected to the other coil 32, and an output terminal of the amplifier 35 is connected to a detection output terminal 37 via a diode 36 having the polarity shown. Then, a smoothing capacitor 38 is connected between the detection output terminal 37 and the ground.
In FIG. 7, V11 indicates the output voltage of the signal generator 34, V12 indicates the output voltage of the amplifier 35, and Vout indicates the output voltage of the detection output terminal 37.
[0039]
With this configuration, a high-frequency sine wave signal (current) of, for example, about 10 [kHz] shown in FIG. 8A is input to one coil 31 of the torque sensor 33 at the output voltage V11 of the signal generator 34. It is excited by this and functions as an exciting coil. In response, the other coil 32 generates a sine wave signal according to the principle of a transformer having the magnetostrictive material 12 as a common magnetic core with the one coil 31. Therefore, the sine wave signal (output voltage V12) is always output from the amplifier 35 with a delayed phase as shown by the solid line in FIG. 8B. Then, the output voltage V12 is rectified by the diode 36 and smoothed by the capacitor 38. As a result, the output voltage Vout of the detection output terminal 37 always becomes as shown by a solid line in FIG.
[0040]
In such a situation, when tension is generated in the fishing line 3 by the fish eating the bait and pulling the fishing line 3, as described above, a tensile stress is applied to the magnetostrictive material 12, and the magnetic permeability of the magnetostrictive material 12 is thereby reduced. Since the voltage increases, the coupling efficiency between the one coil 31 and the other coil 32 increases, thereby increasing the maximum value of the output voltage V12 of the amplifier 35 as shown by the broken line in FIG. 8B. Therefore, the output voltage Vout of the detection output terminal 37 increases its output as shown by the broken line in FIG. 8C.
[0041]
Thus, by detecting the torque acting on the spool 1 when the fishing line 3 is pulled, the tension of the fishing line 3 is detected. In this case, in particular, in this case, the torque sensor 33 controls the one coil 31 to operate. Excitation by a high-frequency current and detection of torque by a change in the output voltage of the other coil 32 can further increase the detection accuracy.
In this case, one coil 31 is provided inside and the other coil 32 is provided outside, but the reverse may be adopted.
[0042]
[ThirdBasic configuration of]
The third shown in FIGS. 9 and 10Basic configuration ofFirst, as shown in FIG. 9, a spool 42 is attached to and supported at one end on the left side of the spool shaft 41 in the drawing, and a hollow rotor shaft 43 is mounted on the outer periphery of an intermediate portion of the spool shaft 41. . A rotor 44 is attached to and supported at one end of the rotor shaft 43 (also on the left side in the figure), and a hook 45 of the rotor 44 hooks a middle part of the fishing line 3 wound around the spool 42. ing.
[0043]
A driven gear 46 is provided at the other end (right side in the drawing) of the rotor shaft 43, and a driven gear 47 is meshed with the driven gear 46. A handle 50 having a knob 49 is attached to the rotation shaft 48 of the drive gear 47. When the angler rotates the handle 50 clockwise, the handle 50 is moved from the drive gear 47 to the driven gear 46 as shown by an arrow C. , The rotor 44 is rotated via the rotor shaft 43, and the rotor 44 winds the fishing line 3 hooked on the hook 45 onto the spool 42.
[0044]
Further, an output shaft 51a of a reciprocating mechanism 51 is connected to the other end of the spool shaft 41 (also on the right side in the drawing). , And converts the reciprocating motion into reciprocating motion. The reciprocating motion is transmitted from the output shaft 51a to the spool shaft 41, whereby the spool 42 moves in the axial direction indicated by an arrow D via the spool shaft 41. It reciprocates and winds the fishing line 3 evenly.
[0045]
The clutch 52 is provided on the driven gear 46 side of the intermediate portion of the rotor shaft 43. The clutch 52 is also a one-way clutch, and the rotor shaft 43 and the rotor 44 are wound with the fishing line 3 (rotational force is transmitted in the direction of arrow C and restrained in the opposite direction), and the fishing line 3 is fed out ( (Free to rotate in the direction opposite to arrow C).
[0046]
In this case, a torque detecting shaft 53 constituted by a part of the rotor shaft 43 is located between the clutch 52 and a portion of the rotor shaft 43 supporting the rotor 44. A torque sensor 54 is provided between the outside and the periphery. As shown in FIG. 10, the torque sensor 54 is provided on the outer periphery of the torque detection shaft 53 in the same manner as the above-mentioned uneven portion 14 (the direction of rotation is such that the rotation of the rotor 44 in the fishing line payout direction is the same as the rotation of the spool shaft 2). Is reversed. Therefore, a concavo-convex portion 55 is formed, and a magnetostrictive material 56 provided by plating the surface of the concavo-convex portion 55 is provided with a gap of 0.5 [mm] around the outer periphery thereof. And a coil 57 provided so as to surround the magnetostrictive material 12.
[0047]
Thus, the mode of torque detection in this case is the first type.Basic configuration ofThe same is true. Therefore, the torque acting on the rotor 44 when the fishing line 3 is pulled is detected by the magnetostrictive torque sensor 54, whereby the tension of the fishing line 3 is detected.
In this case, the magnetostrictive material 56 of the torque sensor 54 isBasic configuration ofSimilarly, by providing the torque detection shaft 53 by plating, productivity can be improved as compared with the one provided by adhesion, and there is no fear of peeling, and reliability can be improved. Further, since there is no adhesive layer, the torque acting on the spool 42 is correctly applied to the magnetostrictive material 56, and the detection accuracy can be increased.
[0048]
In addition, a magnetostrictive material 56 which needs to have a direction substantially parallel to the direction of the main stress in the tensile direction acting on the torque detecting shaft 53 when a torque in the fishing line payout direction is applied to the rotor 44 is attached to the torque detecting shaft 53. It can be provided only by plating the surface of the uneven portion 55 formed on the outer peripheral portion of 53, and the effect that the productivity can be further improved is also the first effect.Basic configuration ofCan be obtained as well.
Also in this case, the magnetostrictive material 56 may be plated in a strip shape on the smooth surface of the torque detection shaft 53 at the above-mentioned predetermined inclination angle.
[0049]
In addition, since the torque sensor 54 has one coil 57 and the torque sensor 54 detects the torque based on a change in the inductance of the coil 57, the torque sensor 54 can be made compact, and is suitable for a small and lightweight fishing reel. The first possible effectBasic configuration ofCan be obtained as well.
Regarding the torque sensor 54, the secondBasic configuration ofBy changing the torque sensor 33 as shown in FIG.Basic configuration ofA similar function and effect may be obtained.
[0050]
[Fourth basic configuration]
Shown in FIGS. 11 to 14Fourth basic configurationIn FIG. 11, first, as shown in FIG. 11, a detection output of the torque sensor (the torque sensor 11 in the illustrated example) is input to a control device 61 which is a control means. The control device 61 has the above-described detection circuit shown in FIG. 4, and further generates a display signal representing detection data from the detection output Vout thereof, and outputs it to the display device 62 for display. Has functions. In this case, the display signal is the one shown in FIG. 12 in which the detection output Vout is continuously shown at every moment, and the angler can know the tension of the fishing line by looking at the display device 62 displaying this. . In this display, the greater the change in the waveform, the greater the tension of the fishing line 3 is.
[0051]
In addition, the control device 61 has a function of a hit judging means for judging a fish hit based on the detection result of the torque sensor. More specifically, the control device 61 receives an input of reference data from a reference data storage device 63 storing reference data as shown in FIG. In this case, the reference data defines the reference value of the amount of change in the magnitude per predetermined time t with respect to the detection output Vout, and the predetermined time of the detection data based on the actual detection result of the torque sensor shown in FIG. The amount of change in the size per t is compared with that, and if it is within the range of the reference data, it is determined that a fish has hit.
Thus, the hit of the fish is determined while the tension of the fishing line 3 is detected. Also, the determination of the hit of the fish is made more accurately based on the comparison result with the reference data.
[0052]
Then, when it is determined that the fish has hit, the determination signal is output to the notifying device 64, which is a notifying unit, to notify the user. The notification device 64 is configured to provide notification by sound from a buzzer, light from a lamp, LED, or the like, display by a character, symbol, illustration, or the like on an LCD, vibration from a vibrator, or the like. You can know.
[0053]
[Of the present inventiononeExample]
As shown in FIG.oneIn the embodiment,Basic configuration of 4And a detection data storage device 71, in which the control device 61 stores detection data based on actual fishing results (in this case, detection data per predetermined time based on the detection result of the torque sensor). (The amount of change in size). The detection data storage device 71 stores the input data and inputs the input data to the reference data storage device 63 as recording data.
[0054]
Accordingly, in this case, the reference data is recorded data based on actual fishing results, and is input to the control device 61. Then, the control device 61 compares this with the amount of change in magnitude per predetermined time t for the detection data based on the detection result of the torque sensor thereafter, and based on the comparison result, If the amount of change in the size of the fish is at the same level as the recorded data, it is determined that the fish has hit. Thus, in this case, the hit of the fish can be more accurately determined based on the result of comparison with the recorded data of the actual fishing results.
[0055]
[No.5Basic configuration]
As shown in FIG.5In the basic configuration of the first embodiment, a second driven gear 81 is mounted on the side (left side in the figure) of the spool shaft 2 opposite to the handle 8 side of the first basic configuration, and a driving gear 82 is mounted on the driven gear 81. The driving gear 82 is rotated by a motor 83 which is an electric means. Therefore, in this case, when the motor 83 is energized, the rotational power is transmitted from the drive gear 82 to the driven gear 81, the spool 1 is rotated via the spool shaft 2, and the fishing line 3 is wound around the spool 1. That is, in this case, the winding of the fishing line 3 is performed electrically.
[0056]
In this apparatus, the winding of the fishing line 3 by the electric motor is executed when the control device 61 determines that the fish hits. Thereby, when the fish hits, the necessary fishing line 3 is automatically wound up, and the usability can be improved.
[0057]
It should be noted that the present inventiononeExample, and5In the basic configuration of the first embodiment, the torque sensor and the detection circuit may be implemented in place of the torque sensor 33 and the detection circuit of the second basic configuration. Further, the fishing line 3 may be wound around the spool 1 by rotating the rotor 44 having the third basic configuration instead of rotating the spool 1 to wind it.
[0058]
Also, all basic configurations andFruitThrough the embodiment, the torque detection shaft may be constituted by a shaft different from the spool shaft 2 and the rotor shaft 43.
Furthermore, the detection result of the torque sensor may be applied to a mechanism for preventing the breakage of the line by allowing the spool 1 and the rotor 44 to rotate in the feeding direction to some extent when an excessive tension is applied to the fishing line 3. .
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention.
