DETAILED DESCRIPTION OF THE INVENTION

[0001]

By the way, conventionally, at the initial stage of purchasing an electric reel,
Alternatively, when a new fishing line is wound on a spool, for example, bobbins around which the fishing line is wound in units of 100 m are prepared in a number corresponding to the required line winding capacity (for example, No. 6-300 m).
If so, three bobbins are connected) and the fishing line is automatically wound by driving a spool motor on a spool.

[0004]

However, by driving the spool motor as described above, the maximum allowable amount (for example, 6
No. -300m) when winding the fishing line on the spool, it depends on the performance of the spool motor and the spool size.
It takes about 3 minutes to wind up. For this reason, the angle of the angler or the clerk often moves away from the electric reel or away from the position for a short period of time. Due to the influence, the fishing line is wound too much beyond the maximum spool diameter (limit winding capacity) of the spool and the winding line of the fishing line comes into contact with each part of the reel body, or the end of the fishing line wound on the bobbin. Part of the level wind mechanism attached to the reel body, the fishing line comes off from the line guide, and a different phase occurs between the position of the line guide and the line winding position on the outer periphery of the spool, resulting in a poor winding state. Problems have been pointed out, such as that the fishing line cannot be fed smoothly.

The present invention has been devised in view of such circumstances, and when a spool motor is driven to automatically rewind a maximum allowable amount of fishing line onto a spool, careless overwinding of the fishing line is prevented. It is an object of the present invention to provide an electric reel which prevents the electric reel.

In the present embodiment, like the yarn length measuring device disclosed in Japanese Patent Application Laid-Open No. 4-276510,
A timer 55 incorporated in the control means 32 measures a time difference Δt until the ultrasonic wave emitted from the ultrasonic sensor 27 is received by the ultrasonic sensor 29, and based on the time difference Δt, the CPU 33 Surface 31 and both ultrasonic sensors 2
The distance a between the first and second spools 9 and 29 is calculated by the following formula: distance a = sonic speed 331 (m / sec) × 1/2 × Δt (1) stored in the ROM 35, and The line diameter D of the wound fishing line 23 is calculated by the following equation: line diameter D = (ba) × 2 (2) stored in the ROM 35. In this equation, b is the distance between the ultrasonic sensors 27 and 29 and the axis of the spool shaft 8 as shown in FIG.

Based on the actual rotation speed N of the spool 9 measured by the rotation sensor 45 and the yarn winding diameter D calculated by the above equation (2), the CPU 33 calculates the yarn length L = π stored in the ROM 35. D · N (3) The thread length L is calculated from the equation (3), and the calculation result is displayed on the display 25 via the output interface 41.

Thus, the fishing reel 57 according to the present embodiment
Has the following features in order to prevent the careless overwinding of the fishing line 23 when the spool motor 11 is driven to newly wind the fishing line 23 around the spool 9 in addition to the same configuration as the conventional one as described above. Having. That is, the ROM 35 stores the maximum line diameter DM of the fishing line 23 according to the shape of the spool 9 mounted on the reel body 3.

When the angler operates the changeover switch 49 on the operation panel 21 to switch the control means 32 to the "winding mode" when newly winding the fishing line 23 on the spool 9, the data is stored in the ROM 35. The maximum thread diameter D _{M for} each spool is displayed on the display 25, and each time the angler operates the setting switch 51, the maximum thread diameter D _M for each spool stored in the ROM 35 is sequentially switched. When the angler presses the setting switch 51 at the required maximum thread diameter DM for several seconds while watching such a display, the maximum thread diameter DM is selected and written in the RAM 37.

After determining the maximum line diameter DM in this way, the angler connects the fishing line 23 wound around the bobbin to the spool 9 and drives the spool motor 11 by operating the power lever 15. , The fishing line 23 is wound around the spool 9. Simultaneously with the driving of the spool motor 11, an ultrasonic wave is emitted from the ultrasonic sensor 27 to the winding surface 31 of the fishing line 23, and the reflected wave is transmitted to the ultrasonic sensor 2.
9 is measured by the timer 55, and based on the time difference Δt, the CPU 33 calculates the winding surface 31 and the two ultrasonic sensors 27, from the above formula (1).
The distance a between the fishing line 29 and the fishing line 23 is calculated, and the line winding diameter D of the fishing line 23 being wound on the spool 9 is calculated by the above formula (2).

Then, the CPU 33 determines that the measured thread diameter D is a predetermined value before the maximum thread diameter DM written in the RAM 37, that is, as shown in FIG. At this point, a command is sent to a spool motor drive circuit (not shown) to stop the spool motor 11. Therefore, after that, the remaining fishing line 23 may be wound around the spool 9 by manually rotating the handle 13 while checking the winding state, thereby avoiding the trouble of overwinding by the motor power.

After the winding of the fishing line 23 is completed, the changeover switch 49 is operated to switch the control means 32 to the "line length measuring mode". Thereafter, the ultrasonic sensors 27 and 29 and the rotation sensor 45 The same yarn length measurement as in the prior art is performed. Since the present embodiment is configured as described above, as described above, the angler
Is determined, the fishing line 23 wound around the bobbin is connected to the spool 9, and the spool motor 11 is driven by operating the power lever 15, so that the fishing line 23 is wound around the spool 9.

When the spool motor 11 is driven in this manner, an ultrasonic wave is emitted from the ultrasonic sensor 27 to the winding surface 31 of the fishing line 23, and a time lag until the reflected wave is received by the ultrasonic sensor 29. Δt is measured by the timer 55,
Then, based on the time difference Δt, the CPU 33 calculates the line winding diameter D of the fishing line 23 being wound on the spool 9 from the above formulas (1) and (2).

The CPU 33 calculates the calculated thread winding diameter D.
Reaches the maximum thread diameter DM-1 mm, a command is sent to the spool motor drive circuit to stop the spool motor 11. Thereafter, the angler only has to wind the remaining fishing line 23 around the spool 9 by operating the handle. After the winding of the fishing line 23 is completed, the changeover switch 49 is operated to switch the control means 32 to the "line length measurement mode". Then, the same yarn length measurement as in the related art is performed.

As described above, in the present embodiment, the electric reel 57
When the spool motor 11 is driven to newly wind the fishing line 23 with the maximum allowable amount on the spool 9 at the initial purchase of the fishing line or when the new fishing line 23 is wound around the spool 9, the line winding diameter D of the fishing line 23 becomes Since the spool motor 11 is configured to stop automatically when the diameter reaches DM-1 mm, it is possible to prevent careless overwinding of the fishing line 23 even when a fisherman or a clerk is not present.

Therefore, according to the present embodiment, the winding surface 31 of the fishing line 23 does not come into contact with each part of the reel body 3 due to the excessive winding of the fishing line 23, and the spool motor 11 does not generate heat. There is no danger that the end of the fishing line 23 easily comes off the line guide of the level wind mechanism, and a different phase occurs between the position of the line guide and the line winding position on the outer periphery of the spool.

When pressed for a second, the maximum thread diameter DM is selected and written into the RAM 37.

When the angler operates the power lever 15 to drive the spool motor 11 after selecting the maximum line winding diameter DM, the fishing line 23 is wound around the spool 9. At the same time, the fishing line 23 is
Is determined based on the time difference Δt between the time when the ultrasonic wave is emitted to the winding surface 31 and the time when the reflected wave is received by the ultrasonic sensor 29.
The PU 33 calculates the line winding diameter D of the fishing line 23 wound around the spool 9 by the calculation formula (2) stored in the ROM 35, and then calculates the spool diameter D measured by the rotation sensor 45.
(3) based on the actual rotation speed N and the calculated thread diameter D.
Consists formula to continue calculating the winding amount L ₁ of the fishing line 23.

When the measured thread diameter D reaches a predetermined diameter shown in FIG. 4, for example, the thread diameter 2 / DM which is half the maximum thread diameter DM, the CPU 33 calculates the thread diameter D by the above formula (3). the winding amount L ₁ that is computed by doubling, which a fishing line 2
The maximum thread amount LM of No. 3 is stored in the RAM 37. The winding amount of the predetermined amount before the winding amount L ₁ is the maximum winding amount LM of being wound fishing line 23,
That is, in this embodiment, when the winding amount L ₁ of the fishing line 23 reaches the maximum winding amount LM -20m, CPU33 is adapted to stop the spool motor 11 by sending a command to the spool motor drive circuit.

Thereafter, the remaining fishing line 23 may be sequentially wound up by operating the handle. After the winding of the fishing line 23 is completed, the changeover switch 49 is operated to switch the control means 32 to the "line length measurement mode". Then, thereafter, the yarn length measurement similar to the conventional one is performed by the ultrasonic sensors 27 and 29, the rotation sensor 45, and the like. Since other configurations are the same as those of the above-described embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.
