DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spool for winding a fishing line and a fishing reel provided with a clutch mechanism for allowing free rotation of the spool in a cut state. More specifically, the fishing line is quickly unwound from the spool. It is about technology.

[0002]

2. Description of the Related Art Conventionally, a fishing reel constructed as described above is disclosed in Japanese Utility Model Laid-Open Publication No. Hei 2-131871, and in this conventional example, a clutch mechanism is in a disengaged state and a fishing line is set to a predetermined length. When the electric motor is fed out for a length or a predetermined time or more, the drive of the electric motor is started, and the driving force of the electric motor is transmitted to the spool to facilitate the payout of the fishing line.

[0003]

Considering the input of a device in boat fishing, in this type of fishing, as described above, after the clutch mechanism is turned off and the input of the device is performed, The fishing line is paid out from the spool by the weight of the work, and the work is lowered.In the above-described conventional example, the drive of the electric motor is automatically performed when the above-described predetermined condition is satisfied after the disconnection operation of the clutch mechanism is detected. Since it starts, it has a good surface that the resistance from the backlash prevention cast controller, level wind mechanism etc. is offset by the driving force of the electric motor at the time of this descent to increase the descent speed of the work in progress. Has become.
In addition, in squid fishing, especially in squid fishing, after the captain detects a group of squid with a fish finder, the captives are thrown in at the same time according to instructions to the captain, but since a false bait is used for the mechanism, It is also known that a large amount of squid is caught on the device that descended to the depth of the shelf the fastest, and for this reason, the spool rotation was assisted by the driving force of the electric motor and the device was driven at high speed, as in this conventional example A descending technique has been proposed.

However, since the force for driving the spool in the fishing line payout direction at the time of loading the work cancels out the resistance of a system associated with the spool such as the level wind mechanism as described above, the driving force is larger than this resistance. In this case, the rotational speed of the spool in the fishing line payout direction is excessively increased, causing not only backlash, but also wasteful consumption of electric power, and there is room for improvement. In particular, in boat fishing, since the tension acting on the fishing line is greatly increased or decreased due to the movement of the boat, if the spool is strongly driven in the fishing line payout direction as described above, the reduction in the tension of the fishing line due to the driving of the motor, It is often desired that the fishing line be slackened due to a decrease in the tension of the fishing line due to the fluctuation of the fishing line, leading to backlash. In the conventional example, backlash caused by overdriving of the electric motor is not suppressed. For example, when the voltage of a power supply for supplying electric power to the electric motor is increased, the electric motor is driven at a high torque and a high speed. The spool may be driven at a high speed under the circumstances that can be driven.

An object of the present invention is to provide a fishing reel which suppresses backlash caused by overdriving without impairing a favorable surface in which the driving force of an electric driving means such as an electric motor assists in feeding of fishing line. It is in the point that it is configured.

[0006]

In order to achieve the above object, a fishing reel according to the present invention comprises a spool for winding a fishing line, a clutch mechanism for allowing free rotation of the spool in a cut state, and the clutch mechanism. An electric driving means for driving the spool in a fishing line payout direction when the cutting is in a cutting state; a torque sensor for detecting a torque acting on the spool when the electric drive means is driven in a fishing line payout direction ; Fishing line payout direction by electric drive means
An upper limit value of the torque acting on the spool when driving in the torque upper limit value is set, the torque value detected by the torque sensor to the feeding direction fishing line by the electric drive means so as to be smaller than the torque upper limit value
And torque control means for controlling the driving of the motor. Further, in the above fishing reel, the torque control means includes the electric drive means together with the torque upper limit value.
The lower limit of the torque acting on the spool at the time of driving in the fishing line payout direction by the torque lower limit is set, the torque value detected by the torque sensor is between the torque lower limit and the torque upper limit It is preferable that the electric drive means controls the drive in the fishing line payout direction so as to take a value. In the above fishing reel, a speed sensor for detecting a speed of the fishing line fed from the spool and a speed upper limit value which is an upper limit value of the speed of the fishing line fed from the spool are set. A method of feeding out the fishing line by the electric driving means so that the speed of the fishing line detected by a sensor is smaller than the speed upper limit value.
It is preferable to have speed control means for performing drive control in the direction . The operation and effect of the present invention are as follows.

[0007]

When the above features are configured as shown in FIGS. 1 to 8, for example, when the clutch mechanism C is disengaged and the spool 5 is driven by the electric driving means A in the fishing line payout direction, the electric driving means A In a situation where the power value supplied to the spool 5 can rise above the preset upper limit, the torque acting on the spool 5 does not rise above a predetermined value due to the suppression of the supply power by the control means 17, and Even in a situation where the linear speed of the fishing line 4 paid out from the spool 5 can be increased to a speed equal to or higher than a preset speed, the supply of power by the control means 17 is suppressed, so that the fishing line 4
Is prevented from rising above the preset linear velocity. That is, in the present invention, while the spool 5 is driven in the fishing line payout direction by electric power as in the conventional case, even when the voltage of the power supply increases,
This is because the torque acting on the spool 5 or the speed of the fishing line 4 does not rise above the preset upper limit and the spool 5 is driven at high speed.
In the control shown in FIG. 8, the torque of the spool 5 causing backlash and the rotational speed of the spool 5 are previously obtained by actual measurement, and the upper limit of the torque is set to 15 based on the result.
g · cm, and the upper limit of the fishing line payout linear velocity is set to 300 m / min.

[0008]

Accordingly, a fishing reel that suppresses backlash caused by overdriving without losing the favorable surface of assisting the feeding of the fishing line with the driving force of the electric driving means such as an electric motor can be reasonably provided. It was composed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, a level winding mechanism and a fishing line 4 that reciprocally drive the line guide 3 in the left and right directions by rotating the screw shaft 2 between the left and right side cases 1 and 1 that constitute the reel body. A spool 5 for winding is disposed, and a handle 6, a drag operating tool 7, a clutch lever 8, and a cast controller 9 are provided on the right side case 1 side. Thus, a fishing reel used for boat fishing is provided with the control case 10.

A spool shaft 11 that rotates integrally with the spool 5 is supported on left and right side cases 1 and 1, and an engaging portion 11 A formed on the spool shaft 11 and a clutch sleeve 12 that can be freely disengaged are attached to the spool shaft 11. A handle shaft 13 which is slidably fitted to the outside and which is connected to the handle 6
A drag mechanism 14 is fitted to the outside of the clutch sleeve 12, an output gear 14A of the drag mechanism 14 is engaged with an input gear 12A of the clutch sleeve 12, and a power from an output gear 15 provided on the spool shaft 11 is transmitted to an intermediate gear. A transmission system for transmitting to the input gear 2A of the screw shaft 2 via the shaft 16 is formed.

Further, a clutch mechanism C is constituted by the engaging portion 11A of the spool shaft 11 and the clutch sleeve 12.
The clutch mechanism C is switched between an on state and an off state by operating the clutch lever 8 (an operation system is not described in detail), and the cast controller 9 is brought into contact with the spool shaft 11 by its rotation operation. Change power 1
The configuration is such that the value of the braking force acting on the pool 5 can be adjusted.

The control case 10 includes a control device 17 (an example of control means) comprising a microprocessor,
A plurality of magnets 18 embedded in the flange of the spool 5
And a reed switch type counter sensor 19 for counting the magnetic action of
A liquid crystal display 20 for outputting the amount of payout of the fishing line 4 based on the count signals 9 and 19, and a plurality of control switches 21 # are provided.

This reel is provided with an electric drive means A for assisting the rotation of the spool 5 to increase the descent speed of the tackle when the clutch mechanism C is disengaged and the tackle is put into the sea. The electric driving means A includes a ring-shaped permanent magnet 22 formed on a flange portion of the spool 5 and a ring-shaped field coil 23 disposed near a rotation locus of the permanent magnet 22. The coil 23 is supplied with electric power from a battery 26 incorporated in a thumb rest 25 via a driver 24 (built in the control case 10) driven by a signal from the control device 17, and is rotated by the field coil 23. It is configured to generate a magnetic field. The permanent magnet 22 has an N-pole and an S-pole alternately arranged along the inner peripheral surface of the ring portion. A magnetic member 27 made of a magnetic material such as iron is externally fitted on the outer periphery of the permanent magnet 22 to form a magnetic circuit. The field coil 23 is provided with a plurality of coils 23A # in its circumferential direction. The field coil 23 is housed in a doughnut-shaped watertight case 28 and a plate 29 for closing the spool insertion hole. The air gap with the permanent magnet 22 is uniformly maintained at a small interval by being externally fitted to the positioning portion 29A which is formed to protrude.

The reel has a control system as shown in FIG. 5. In this control system, a current supplied from the battery 26 to the field coil 23 via the driver 24 is converted into a voltage signal by a resistor R. After that, a current sensor 30 having a structure to be converted into a digital signal by the A / D converter 30A and input to the control device 17 is provided. As shown in FIG. 7, in this control, when the clutch mechanism C is disengaged and the device is put into the sea (the state of the clutch mechanism C may be determined by sensors), the counter sensors 19, 19 A signal is input to determine the rotation direction of the spool 5 (Step # 101, Step # 102),
If the feeding of the fishing line 4 is continuously performed, the field coil 23 is driven so as to apply a driving force to the spool 5 (Step # 103).

The driving force of the transmission driving means A is set weak enough to cause a slip between the field coil 23 and the permanent magnet 22 when the summing is performed.
Each of the plurality of coils 23A # constituting the field coil 23 is sequentially energized in a direction indicated by an arrow F in FIG. 2 to generate a rotating magnetic field. Incidentally, the driver 24 includes an element such as a switching transistor, and at the time of energization, the energizing direction is switched between forward and reverse so as to obtain a driving force by an attractive force and a repulsive force on the permanent magnet 22.

This control is performed by the control switch 21.
Is artificially released by the operation of a predetermined one of
Alternatively, when the device lowers to the shelf depth set last time, the power supply to the field coil 23 is stopped to end the control (steps # 104 to # 106). In addition, the depth of the shelf set last time is the depth of the device that caused a hit when the device was previously inserted, or the depth of the device that was maintained for a relatively long time last time, or artificially from the outside. The depth indicates an input value, and the depth is set in a memory or the like of the control device (control operation is not described in detail). In this control, when the field coil 23 is driven, the torque applied to the spool 5 so as not to cause backlash due to the driving force and the control of the feeding speed of the fishing line 6 not exceeding a preset value are performed in a subroutine. In this control, as shown in FIG. 8, a current having a value according to a predetermined parameter is supplied to start driving (step # 201), and a signal of the current sensor 30 is input, as shown in FIG. If the current value is equal to or greater than the set value, the parameter is changed to the current value decreasing side. If the current value is equal to or less than the set value, the parameter is changed to the current increasing side (steps # 202 to # 206). This current value corresponds to the torque acting on the spool 5 from the field coil 23, and the relationship between this current value and the torque value is measured in advance, and the torque acting on the spool 5 in the measurement of the current value is obtained. When the torque value reaches 15 g · cm or more, the current value is reduced. Conversely, when the torque value is low, the torque is increased to increase the payout speed of the fishing line 6.

Next, the linear speed of the fishing line 6 in the feeding direction is obtained based on the signals of the counter sensors 19, 19, and when this speed has reached a predetermined value or more, the parameter is changed to the current value decreasing side. If the value is equal to or smaller than the set value, the parameter is changed to the current increasing side (steps # 207 to # 21).
2 steps). In this control, the linear speed of the fishing line 6 becomes 300
When the speed reaches m / min, the current value is reduced. Conversely, when the speed is lower than the predetermined value, the current value is increased to increase the payout speed of the fishing line 6. As shown in FIG. 6, the current value is controlled by intermittently driving the driver 24 to supply the current intermittently to the field coil 23, and the duty cycle of the intermittent current, that is, the ON of the intermittent drive cycle. The adjustment is performed by adjusting the time T.

[Alternative Embodiment] The present invention, in addition to the above embodiment,
For example, it is possible to control only the torque acting on the spool, or to control only the linear speed of the fishing line fed from the spool, and to apply to an electric reel as in the conventional example. It is also possible. Further, according to the present invention, it is possible to configure such that the value of the upper limit torque or the upper limit speed of the fishing line payout speed is set to an arbitrary value in accordance with the structure of the fishing reel. Can be configured so that the value of can be changed artificially. Further, in the present invention, the electric driving means can be constituted by an electric motor.
