[Prior art]
2. Description of the Related Art In general, when performing fishing on a deep-sea fish layer such as boat fishing, an electric reel for fishing (hereinafter, referred to as “electric reel”) is widely used.
As is well known in the art, this electric reel winds a fishing line by rotating a spool by driving a spool motor mounted on a reel body. Recently, many electric reels have a rotating body ( For example, there is provided a yarn length measuring device that measures the yarn length from the number of revolutions of the spool) and displays the measured length on a display, and the angler sets a gimmick at a predetermined shelf position based on the display on the display. It can be paid out.
[0003]
Further, in order to improve the fishing results, today, based on the measured values of the above-described line length measuring device, the clutch mechanism is switched to the clutch ON by an actuator such as a motor or a solenoid to feed out a tackle (fishing line) on a predetermined shelf. A shelf stop device that automatically stops at the position, and a boatslip that automatically stops the drive of the spool motor when the device is wound up to the boatslip stop position to protect the rod tip when winding the fishing line. At present, functions such as an automatic stop device are incorporated, and multifunctionality and computerization are progressing.
[0004]
Japanese Unexamined Patent Application Publication No. 11-89488 discloses an improvement in this type of automatic boat-slide stop device, taking into account the overrun that occurs when the drive of the spool motor is stopped, in accordance with the previous overrun amount. An electric reel is disclosed in which by adjusting the value, the mechanism is always stopped at the boat stop position even if the spool motor overruns at the next winding.
[0005]
[Problems to be solved by the invention]
However, in this type of boatslip stop control based on rotation detection of a rotating body, the influence of load fluctuations (changes in tension) during the winding operation is greater than the effects of the winding speed and the last stop position of the tackle. In the conventional example of Japanese Patent Application Laid-Open No. H11-89488, there is a possibility that the boat stop position is still unstable, and the rod tip may be broken due to excessive winding.
[0006]
The present invention has been devised in view of the above circumstances, and has as its object to provide an electric reel in which a stable boat stop at a boat stop position is achieved in consideration of a load variation during winding of a fishing line. I do.

And a control unit for driving and controlling the spool motor. The control unit obtains a new motor driving condition based on a difference between the detection value of the detection unit and the power value stored in the storage unit. In addition, the spool motor is controlled to automatically stop on the side of the boat under the motor driving conditions, and new motor driving conditions and detected values are sequentially stored and updated in the storage means.
[0008]

[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0012]
FIG. 1 shows an embodiment of the electric reel according to claims 1 and 2, wherein 1 is a frame of the reel body 3, 5 and 7 are side plates attached to the left and right sides of the frame 1, A spool 9 is rotatably supported between 5 and 7 via a spool shaft.
The spool 9 is rotated by driving of the spool motor 11 or winding operation of the handle 13 so that the fishing line is wound. The inner periphery of the spool 9 has a maximum winding of the fishing line around the axis of the spool 9. An annular prescribed winding diameter level (annular groove) 14 slightly smaller in diameter than the diameter is formed.
[0013]
The spool motor 11 is housed in a motor case integrally formed with the frame 1 in front of the spool 9.
A power lever (motor output adjuster) 15 for adjusting the motor output of the spool motor 11 is provided in the upper front of the side plate 7 in the same direction as the rotation direction of the handle 13 as in the case of the electric reel disclosed in Japanese Utility Model Laid-Open No. 5-76273. When the power lever 15 is operated, the CPU of the control means, which will be described later, mounted in the control box 17 outputs the duty ratio of the pulse signal corresponding to the operation amount of the power lever 15 to the spool motor 11. The duty ratio of the energization rate to the spool motor 11 is controlled so that the spool motor 11 is continuously controlled from a motor stopped state to a maximum value (0 to 100%).
[0014]
Behind the side plate 7, a clutch lever 19 of a clutch mechanism mounted in the side plate 7 is attached. When the clutch lever 19 is turned on / off, the spool motor 11 and the handle 13 are moved to the spool 9. Is transmitted / cut off.
On the other hand, a magnet 21 is mounted on the end surface of the spool 9 on the side plate 5 side, and a pair of reed switches 23 are mounted on the frame 1 so as to oppose the rotation trajectory of the magnet 21. The rotation detecting means 25 for detecting the number and the rotation direction is constituted.
[0015]
The operation panel 27 on the upper surface of the control box 17 includes a display 29 for displaying the line length, and a mode changeover switch 30 for resetting the control means 37 between the basic data input mode and the actual fishing mode, a reset switch 31, and a sideboard. A switch 32, a shelf memo switch 33 and the like are provided.
[0016]
FIG. 2 is a control block diagram of the electric reel 35 according to the present embodiment. In the figure, reference numeral 37 denotes a control means (microcomputer) for performing thread length calculation, thread length display, and data writing control. (Central Processing Unit) 39 which controls and manages a program memory, a data memory and an input / output device, and executes calculations and transfer processes necessary for processing a given job; , A RAM 45 for storing the calculation results of the CPU 39, basic data to be described later, data of the total line length value of the fishing line 43, and the like, and an up / down for counting the rotation pulse signal of the spool 9 taken in from the reed switch 23. A counter 47 and input / output interfaces 49 and 51 are provided, and these are connected to the CPU 39 via the bus 53.
[0017]
The input interface 49 is connected to the mode changeover switch 30, the reset switch 31, the shore switch 32, the shelf memo switch 33, the power lever 15, and the like, and the output interface 51 is connected to a display drive circuit and a motor drive circuit. The display 29 and the spool motor 11 are connected via the.
In FIG. 2, D0, D1, D2, and H are:
D0  : Bottom diameter D1 of spool 9  : The line winding diameter D2 when the fishing line 43 is entirely wound around the spool 9: The line winding diameter H when the fishing line 43 is wound to the specified winding diameter level 14: The groove depth of the spool 9 up to the specified winding diameter level 14 Is shown.
[0018]
Then, in the ROM 41 of the control means 37, as with the yarn length measuring device disclosed in Utility Model Registration No.
L = dNa ² + eNa (1)
d = −πH / N: constant (2)
e = π (D0 + 2HNe / N): constant (3)
However,
Na: actual rotation speed of the spool 9 at the time of actual fishing Ne: total rotation speed N of the spool 9 up to the thread diameter D1 Each calculation formula of the rotation speed of the spool 9 up to the winding diameter level 14 is stored. Prior to this, in the basic data input mode, when the spool motor 11 is driven by operating the power lever 15 to wind the fishing line 43 around the spool 9, the CPU 39 returns to the winding diameter level 14 measured by the rotation detecting means 25. Based on the number of rotations N of the spool and the total number of rotations Ne of the spool 9 up to the yarn winding diameter D1, constants d and e, which are basic data of the yarn length calculation formula (1), are determined by the calculation formulas (2) and (3). Then, it is set and input to the RAM 45.
[0019]
Thereafter, in the actual fishing mode, the CPU 39 calculates the line length L by executing the calculation formula (1) based on the actual rotation speed Na of the spool 9, and the line length L is displayed on the display 29. It has become so.
Then, in the actual fishing mode, while watching the display on the display 29, the angler operates the shelf memo switch 33, for example, at a position where the device is extended 50 m from the surface of the water, and the CPU 39 stores the depth of 50 m in the RAM 45 as the shelf position. When the display value “0.0 m” of the indicator 29 reset by the operation of the reset switch 31 is used as the winding end and the boat switch 32 is operated at a water depth of 1 m before the winding end, for example, the CPU 39 moves the water depth of 1 m. The RAM 45 is stored as a slip stop position. When the power lever 15 is operated, as described above, the motor output is continuously adjusted from the motor stopped state to the maximum value, and the fishing line 43 is wound on the spool 9. When the CPU 39 reaches the boat stop position, the CPU 39 sends a motor stop command to the spool motor drive circuit to stop the spool motor 11.
[0020]
Thus, the electric reel 35 according to the present embodiment has the following features in addition to the same configuration as the conventional one as described above.
First, as shown in FIG. 2, a detector (detection means) 55 for detecting a motor current value and electric power at the time of winding drive by the power lever 15 is attached to a motor drive circuit (not shown) of the spool motor 11. The detected value detected by the detector 55 is converted into a digital value by the A / D converter 57 and fed back to the control means 37.
[0021]
As described above, in the basic data input mode, the fishing line 43 is wound around the spool 9 by operating the power lever 15, and the basic data (constants d and e in the formula (1)) are set and input to the RAM 45. However, the CPU 39 calculates an electric power value (work amount, load value) Fs of the spool motor 11 from the electric current value, electric power and duty ratio (duty ratio) of the spool motor 11 detected by the detector 55 at the time of driving the motor. Are set and stored in the RAM 45.
[0022]
Next, after the mode changeover switch 30 is operated to switch the control means 37 to the actual fishing mode, when the angler draws out the fishing line 43 together with the tackle, the CPU 39 calculates the line length L from the formula (1) and calculates the line length L. Is displayed on the display 29, and while watching the display on the display 29, as described above, the display value "0.0m" of the display 29 on the surface of the water is taken up at the winding end, for example, at a position 1m below the surface of the water. When the switch 32 is operated, the depth of 1 m is set and stored in the RAM 45 as the boat stop position, and when the shelf memo switch 33 is further operated 50 m below the water surface, the depth of 50 m is set and stored in the RAM 45 as the shelf position.
[0023]
Then, at the time of feeding the fishing line, the CPU 39 measures the total number of revolutions (for example, 1000 revolutions) of the spool 9 from the boat stop position to the shelf position based on the detection signal of the reed switch 23, and sets this as an initial set value N. The data is set and stored in the RAM 45.
Thereafter, when the fishing line 43 is wound by operating the power lever 15 to collect the device (first winding), the CPU 39 determines the first winding power value F1 from the detection value of the detector 55 and the duty ratio. Then, it is determined whether or not this is greater than the power value Fs described above (comparison of F values).
[0024]
And
F1 / Fs × initial setting value N
Is calculated and stored in the RAM 45, and the spool 9 is rotated at the calculated new total spool rotational speed to perform the automatic boathead stop control. It has become.
[0025]
Therefore, for example, when the first winding load is larger than the power value Fs, the total number of spool rotations (for example, 1010 rotations) of the first winding larger than the initial set value N (1000 rotations) is calculated by the above calculation. Calculated from the formula, the device is wound up from the shelf position at the total number of rotations of the spool.
Further, at the time of the next winding operation (second winding operation), it is determined whether or not the newly detected power value F2 is larger than the previous power value F1 (comparison of F values). In the case of (F1 ≒ F2), the spool total rotation number (1010 rotations) is not changed, and the spool 9 is rotated at the same spool total rotation number to perform the shipboard automatic stop control.
[0026]
Then, at the time of the next (third winding) winding drive, it is determined whether or not the newly detected power value F3 is larger than the previous power value F2 (comparison of F values). If it is smaller than the previous power value F2 (F2> F3),
F3 / F2 x previous spool total rotation speed (1010 rotations)
, The total spool number (for example, 1000 rotations) smaller than the previous total spool number (1010 rotations) is calculated, set and stored in the RAM 45, and the calculated new spool total rotation number is calculated. , The spool 9 is rotated to perform a boatslide automatic stop control.
[0027]
Thereafter, the spool total rotation speed is sequentially calculated and updated in accordance with the power value detected at each winding drive, and the boat-boat automatic stop control is performed for each winding drive at the updated spool total rotation speed. It is going to go.
[0028]
In the present embodiment, the fishing line 43 is spooled by operating the power lever 15 after the angler operates the mode changeover switch 30 to switch the control means 37 to the basic data input mode. 9, the basic data (constants d and e of the formula (1)) are set and input to the RAM 45, and at the same time, the CPU 39 detects the current of the spool motor 11 detected by the detector 55 when the motor is driven. The power value (work load, load value) Fs of the spool motor 11 is calculated from the value, the power, and the duty ratio (duty ratio), and is set and stored in the RAM 45 (step S1 in FIG. 3).
[0029]
Next, when the angler operates the mode changeover switch 30 to switch the control means 37 to the actual fishing mode, and then pays out the fishing line 43 together with the tackle, the CPU 39 calculates the line length L from the formula (1) and calculates the line length L. Is displayed on the display 29. While watching the display on the display 29, the angler takes up the display value "0.0m" of the display 29 on the water surface and winds up the boat switch 32 at 1m below the water surface, for example. When operated, the depth of 1 m is set and stored in the RAM 45 as the boat stop position, and when the shelf memo switch 33 is further operated 50 m below the water surface, the depth of 50 m is set and stored in the RAM 45 as the shelf position (step S2).
[0030]
Then, at the time of feeding the fishing line, the CPU 39 measures the total number of revolutions (for example, 1000 revolutions) of the spool 9 from the boat stop position to the shelf position based on the detection signal of the reed switch 23, and sets this as an initial set value N. It is set and stored in the RAM 45 (step S3).
Thereafter, when the fishing line 43 is wound by operating the power lever 15 to collect the device (first winding), the CPU 39 determines the first winding power value F1 from the detection value of the detector 55 and the duty ratio. It is detected and it is determined whether or not this is greater than the power value Fs (steps S4, S5).
[0031]
And the CPU 39
F1 / Fs × initial setting value N
, The spool total rotation speed for the first winding is calculated and set and stored in the RAM 45 (step S6), and the spool 9 is rotated at the calculated new spool total rotation speed so that the shipboard automatic rotation is performed. Perform stop control.
[0032]
Therefore, for example, when the first winding load is larger than the power value Fs, the total number of spool rotations (for example, 1010 rotations) of the first winding larger than the initial set value N (1000 rotations) is calculated by the above calculation. Calculated from the formula, the device is wound up from the shelf position at the total number of rotations of the spool.
Further, at the time of the next (the second winding) winding drive, it is determined whether or not the newly detected power value F2 is larger than the previous power value F1 (steps S4 and S5). In the case of (F1 ≒ F2), the spool 9 is rotated at the same total number of spool rotations as the previous time to perform the boat-boat automatic stop control (step S7).
[0033]
Then, at the time of the next (third winding) winding drive, it is determined whether or not the newly detected power value F3 is larger than the previous power value F2 (steps S4 and S5). If it is smaller than the previous power value F2 (F2> F3),
F3 / F2 x previous spool total rotation speed (1010 rotations)
, A total spool number (for example, 1000 rotations) smaller than the previous total spool number (1010 rotations) is calculated and stored in the RAM 45, and the calculated new total spool number is calculated. , The spool 9 is rotated to perform the automatic boat-stop stop control (step S8).
[0034]
Thereafter, the spool total rotation speed is sequentially calculated and updated in accordance with the power value detected at each winding drive, and the boat-boat automatic stop control is performed for each winding drive at the updated spool total rotation speed. It will go.
As described above, the present embodiment detects the power value at each winding drive in consideration of the load fluctuation at the time of winding the fishing line, and calculates and updates the total number of rotations of the spool according to the power value. According to the present embodiment, it is possible to prevent the rod tip from being broken due to excessive winding, and to always perform the proper rod tip control, since the automatic control of the boatslip is sequentially performed at the total number of rotations of the spool according to the electric power value. Since the device is stopped at the feeding position, there is an advantage that rework is quicker than before and fishing results are improved.
[0035]
In the above-described embodiment, the total spool rotation speed is used as the motor driving condition according to the electric power value. However, it is a matter of course that the present invention is not limited to such a motor driving condition.
[0036]
【The invention's effect】
As described above, the invention according to claim 1 detects a power value for each winding drive in consideration of a load variation at the time of winding the fishing line, and detects the power value for each detected winding drive time. A new motor driving condition is calculated based on the difference from the power value stored in the storage means, and the new power value and the motor driving condition are sequentially stored and updated, and the motor driving condition corresponding to the power value is calculated. According to the present invention, it is possible to prevent the rod tip from being broken due to excessive winding, and to always stop the device at a proper feeding position from the rod tip. This has the advantage that the reversal is quicker and the fishing result is improved as compared with the related art.
[0037]
The invention according to claim 2 utilizes the rotation speed of the spool measured by the yarn length measuring means as a motor driving condition. However, according to the present invention, it is possible to prevent the rod tip from being broken due to excessive winding, and Since the device is always stopped at the proper feeding position from the rod tip, there is an advantage that rework is quicker and fishing results are improved as compared with the related art.
