[Detailed description of the invention]

[0001]

The present invention relates to a fishing reel,
More specifically, the present invention relates to a technique for assisting rotation of a spool in a fishing line payout direction.

[0002]

2. Description of the Related Art Conventionally, there is a fishing reel constructed as described above, as disclosed in Japanese Utility Model Laid-Open Publication No. Hei 2-131871, and in this conventional example, the driving force of an electric motor built in a spool is used. It is configured to assist the rotation of the spool in the fishing line payout direction.

[0003]

Here, in consideration of the input of a device in fishing in a boat, 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 device. The device lowers. Further, in the above-mentioned conventional example, by assisting the rotation of the spool with the driving force of the electric motor, a resistance directly acting on the rotation system of the spool like a cast controller, or a system linked to the spool like a level wind mechanism or the like is used. Is offset by the driving force of the electric motor to increase the descent speed of the in-process.

[0004] The above-mentioned electric reel has a favorable surface in which the descent speed of the in-process can be increased by utilizing the characteristics of the drive system. However, the electric reel is relatively large and is configured to be heavy. Therefore, in fishing that does not target the deep sea, there is a demand for a technique for assisting the rotation of the spool in the fishing line payout direction to increase the descent speed of the work in a small reel, such as a manual reel, as described above. In addition, in squid fishing, especially squid fishing, after the captain detects a group of squids with a fish finder, the gimmicks are thrown in at the same time according to the captain's instruction, but since the artificial bait is used for the gimmick, It is also known that a large amount of squid is caught on a device that descends the earliest to the depth of the shelf, and for this reason, a technique for quickly lowering the device is required.

An object of the present invention is to make a fishing reel for assisting the rotation of a spool with a smooth driving force to increase a descent speed of a work as small and reasonably possible as possible.

[0006]

The feature of the present invention is that a spool is rotatably supported on a reel body, and a conductor,
Form a driven body consisting of either a magnetic body or a permanent magnet,
The reel body is provided with a field coil for applying a rotating magnetic field to the driven body to apply a driving force to the spool in a fishing line payout direction.
Moving means, and adjusting means for changing a relative distance between the field coil and the driven body , wherein the driving means and the adjusting means are provided.
The operation and effect of the control device are as follows.

[0007]

[Action] As shown in FIGS. 1 to 5, when lowering the sea is a mechanism performs turned tackle by operating disengage the clutch mechanism C, the drives the driving means 24 to the field coil 23 By applying a driving force in the fishing line payout direction by energization, the spool 5 is driven by a driving force acting on the driven body 22 from the field coil 23 against a resistance acting from the cast controller 9, the level wind mechanism and the like. If the relative distance between the field coil 23 and the driven body 22 is changed by the adjusting means A during this driving, the driving force acting on the driven body 22 changes. The drive torque can be adjusted. But
Therefore, if the mechanism at the first introduction is changed at the next introduction
In such a case, the relative distance is changed according to the changed lightness.
Further, by changing the driving force acting on the driven body 22,
That is, it is possible to apply a large driving torque. The driven body 22 is composed of a permanent magnet, and the driving unit 24 is
In the case where the fishing line is paid out or the line is wound up in a state in which the field coil 23 is not energized without being operated, the spool 5 having the permanent magnet is provided by the field coil.
By rotating relative to 23, the permanent magnet

it can. That is, in the present invention, the driving force is directly applied to the spool 5 to promote the payout of the fishing line without using the electric motor having the independent structure, and the backlash can be suppressed by using this configuration. Due to this configuration, the resistance acting during the winding operation can be reduced.

[0008]

Therefore, in the case where the fishing reel for assisting the rotation of the spool with a smooth driving force to increase the descent speed of the work is relatively small, and the driven body is constituted by a permanent magnet, Thus, it was possible to suppress the backlash and to reduce the operation resistance during winding. In particular, if the driven body is formed of a permanent magnet, and the field coil is not driven when the device is loaded, and the field coil and the driven body are brought close to each other, for example, as in the case where the motion of the ship is large, There is also an effect that it is possible to set a state in which backlash does not occur even in a situation where backlash is likely to occur.

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. The braking force acting on the spool 5 can be adjusted by changing the force.

As shown in FIGS. 2 to 5, the control case 10 includes a control device 17 comprising a microprocessor and a plurality of magnets 1 embedded in a flange of the spool 5.
A liquid crystal display 20 which incorporates a reed switch type sensor 19, 19 for counting the magnetic action of 8 °, outputs a feeding amount of the fishing line 4 based on the count signal of the sensor 19, 19, and a plurality of control switches 21 It has.

This reel is provided with auxiliary driving means 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 driving means includes a ring-shaped permanent magnet 22 formed on the flange of the spool 5 as shown in FIG.
Become in a ring-shaped field coil 23 disposed in the vicinity of the rotation locus of the permanent magnet 22 (an example of a driven member), driving in the field coil 23 which is driven by a signal from the controller 17 driver as a means 24 (control case 1
) Is supplied from a battery 26 incorporated in a thumb rest 25 to generate a rotating magnetic field in the field coil 23. The rotation of the spool 5 is controlled based on the feedback signal. The permanent magnet 22 has an N-pole and an S-pole alternately arranged along the inner peripheral surface of the ring portion, and an annular member 27 made of a magnetic material such as iron is fitted around 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. Actuator 31 which is externally slidably fitted to a guide portion 29A which is formed so as to protrude therefrom, and which is transmitted via an operation shaft 30 connected to a watertight case 28 of the field coil 23.
It is set at an arbitrary position in the spool axis direction by the driving force of (an example of the adjusting means A). As shown in FIG. 5, in this reel, selection of control for assisting the rotation of the spool 5 in the fishing line payout direction by a signal such as radio waves, infrared rays, and ultrasonic waves from a cordless controller 32 formed independently of the reel body. The control system is configured to perform
The controller 32 has a code converter 32A, a modulator 32B, and a transmitter 32C into which a control code is input.
In addition, a receiving unit 33A, a demodulating unit 33B, and a code converting unit 33C are provided on the reel body side as a remote control system.

In this reel, control is performed as shown in FIG. 6 when a work is put in. In this control, first, a sensor 19,
19, the rotation direction of the spool 5 is determined (# 101 step, # 102 step), the clutch mechanism C is disengaged, and the spool 5 starts rotating in the fishing line payout direction due to the input of a device. Field coil 23
When the motor is not driven, the electric field actuator 23 is driven to move the field coil 23 closer to the driven body 22 side (the spool side), so that a force acting between the field coil 23 and the driven body 22 is controlled. Increase the power to suppress backlash. Next, the controller 32 or
When the auxiliary switch is selected by the control switch 21, the driving force is applied to the spool 5 when a predetermined time elapses, when a predetermined amount of fishing line is fed out, and when the descent speed of the in-process lowers to a predetermined value is satisfied. The field coil 23 is driven to operate (steps # 103 to # 106). When driving the field coil 23, the relative distance between the field coil 23 and the permanent magnet 22 can be changed by operating the control switch 21 to adjust the torque acting on the spool 5. As described above, the reason for applying the braking force to the spool 5 at the time of loading the device is that the resistance of water is relatively small in the initial stage of loading the device, and the device is falling at a sufficient acceleration. This is because it is not necessary to assist in extending the boat, and the backlash is likely to occur even when the boat shakes.

The driving force of the auxiliary driving means is set to be weak enough to cause a slip between the field coil 23 and the permanent magnet 22 when the summing is performed. Are sequentially energized in the direction indicated by 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. Then, this control is artificially released by the operation of the controller 32 or the control switch 21, or the energization to the field coil 23 is stopped when the device lowers to the previously set shelf depth. To end the control (steps # 107 to # 109). 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 reel, the field coil 23 is used when the fishing line is wound by operating the handle.
The field coil 23 is separated from the driven body 22 by driving the electric actuator 31 so as not to apply the braking force from the spool 5 to the spool 5 (Step # 110, Step # 111).
Steps). The electric actuator 31 can be set to an arbitrary position by operating a predetermined one of the control switches 21.

[Alternative Embodiment] The present invention can be implemented as follows in addition to the above-described embodiment. (A) As shown in FIG. 7, the side case 1 is provided so that the adjusting means A can adjust the position of the field coil 23 by manual operation force.
The cam body 36 which rotates around the spool axis is freely supported on the plate 29 supported by the plate 29, and the pin 37 formed in the field coil 23 is engaged with the cam groove of the cam body 36.
By providing a spring 38 for urging the field coil 23 toward the cam body 36, the position of the field coil 23 with respect to the driven body 22 can be arbitrarily determined by operating a lever 39 connected to the cam body 36. . (B) When assisting the rotation of the spool in the fishing line payout direction by driving the field coil, the field coil and the driven body are automatically increased so as to increase the torque acting on the spool as the fishing line payout amount increases. To change the relative distance to. (C) When the spool is rotated in the fishing line winding direction, the field coil is driven in a direction to assist this rotation, and the rotation of the spool is measured by a sensor so as to facilitate the spool operation. The field coil is driven by the synchronized signal. (D) The driven body is made of a conductor such as copper or aluminum, or a magnetic body such as iron. It is to be noted that the driving body having such a configuration may be provided as a plurality of independent small pieces, instead of being formed in a ring shape as in the embodiment. (E) Further, the field coil may not be formed in a ring shape but may be configured to support an independent coil on a plate-shaped frame.
