Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fishing reel, and more particularly to a technique for assisting at least rotation of a spool in a fishing line payout direction.

[0002]

[Prior art]

 Conventionally, there is a fishing reel configured as described above in Japanese Utility Model Laid-Open No. 2-131871. In this conventional example, a drive of an electric motor built in a spool for the purpose of driving a fishing line in a winding direction is performed. The force is used to assist rotation of the spool in the fishing line payout direction when the clutch mechanism is disengaged.

[0003]

[Problems to be solved by the device]

 Here, considering the introduction of a tackle in boat fishing, after the clutch mechanism is operated to input the tackle, the fishing line is paid out from the spool by the weight of the tackle, and the tackle is lowered. Further, in the above-mentioned conventional example, by supporting the rotation of the spool by the driving force of the electric motor, the resistance acting on the spool from the cast controller, level wind mechanism, etc. is offset by the driving force of the electric motor, and the descending speed of the work is increased. It is intended to The above-mentioned electric reel has the good aspect that the characteristics of the drive system are used to increase the descending speed of the work in progress, but since this kind of electric reel is relatively large and heavy, it is constructed. For fishing that does not target the deep sea too much, there is a demand for a technique for assisting the rotation of the spool in the fishing line payout direction in the small reel such as the manual type so as to increase the descending speed of the work in the same manner as described above. Therefore, it is conceivable to incorporate an electric motor inside the reel unit to drive the spool in the fishing line feeding direction, but it is difficult to secure a built-in space for the electric motor in a small reel. In squid fishing, especially squid fishing, after the captain detects a group of squid with a fish finder, he / she inputs the tackle all at once according to the instruction of the captain. It is also known that a lot of squid hangs on the mechanism that descends to the depth of the shelves at the earliest, and for this reason, technology for lowering the mechanism at high speed is required.

In addition, considering the bait casting reel used for bass fishing, this type of reel frequently casts work such as lures, and when a relatively light work is used during casting, Appropriate improvements are often requested because the throwing distance of the work is often reduced by the static inertia of the spool or the resistance from the system associated with the spool. An object of the present invention is to make the fishing reel as small as possible in order to assist the rotation of the spool and increase the descending speed of the work in process or the rotating speed of the spool during casting.

[0005]

[Means for Solving the Problems]

 A feature of the present invention is that a conductor is formed on a spool rotatably supported on a reel body, a rotating magnetic field is applied to the conductor, and a fishing line is delivered to the spool by an induced current generated in the conductor. It is provided with a field coil that gives a driving force in the direction, and is provided with a control device that adjusts the rotation speed of the rotating magnetic field generated in this field coil. The action and effect are as follows. .

[0006]

[Action]

 If the above features are configured as shown in, for example, FIGS. 1 to 5, when the tackle is lowered into the sea, the clutch mechanism C is operated by disengaging the tackle to energize the field coil B to energize the fishing line. By driving in the payout direction, the spool 5 rotates in the fishing line payout direction against the resistance acting from the cast controller 9 and the level wind mechanism by the driving force acting from the field coil B to the conductor A. If the rotation speed of the spool 5 changes during this driving, the rotation speed of the rotating magnetic field by the field coil B is changed to a speed synchronized with the spool 5 via the control device 17. By doing so, it becomes possible to suppress excessive driving or eliminate insufficient driving force. Further, although the field coil B and the conductor A are made to face each other in the present invention, as compared with, for example, the field coil B and the permanent magnet are used, the field coil B is driven without being driven. Even when 5 is rotated, no electric current is generated in the field coil B, and even if the fishing line is wound at high speed, the braking force may act between the field coil B and the conductor A. There is no. That is, in the present invention, since the spool 5 is directly driven by the action of the magnetic force from the field coil B, the size can be reduced and the occurrence of backlash can be suppressed at the same time as compared with a device equipped with an electric motor. It is possible to feed the fishing line without excess or deficiency, and it is also possible to wind the fishing line smoothly despite the formation of this drive system.

[0007]

[Effect of device]

 Therefore, the fishing reel has been made small in size to assist the rotation of the spool without causing backlash and to increase the descending speed of the work in process or the rotating speed of the spool during casting. In particular, in the present invention, when the spool is applied to a reel made of a metal such as aluminum, it is possible to reduce the cost while simplifying the structure without specially forming the conductor. Play.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 4, between the left and right side cases 1 and 1 that form the reel unit, a level wind mechanism that reciprocally drives the thread guide tool 3 in the left-right direction by the rotation of the screw shaft 2, and a fishing line 4. Each of the spools 5 made of resin for winding up is arranged, and a handle 6, a drag operation tool 7, a clutch lever 8 and a cast controller 9 are provided on the right side case 1 side. A control case 10 is provided over the upper parts of the above to form a fishing reel for use in boat fishing.

A spool shaft 11 that rotates integrally with the spool 5 is supported by the left and right side cases 1 and 1, and an engaging portion 11A formed on the spool shaft 11 and a clutch sleeve 12 that can be engaged and disengaged are provided on the spool shaft 11. 11, a drag mechanism 14 is provided so as to be slidably fitted onto a handle shaft 13 and fitted to a handle shaft 13 connected to the handle 6. An output gear 14A of the drag mechanism 14 is connected to an input gear 12A of the clutch sleeve 12. Further, a transmission system for transmitting power from the output gear 15 provided on the spool shaft 11 to the input gear 2A of the screw shaft 2 via the intermediate gear 16 is formed. A clutch mechanism C is configured by the engagement portion 11A of the spool shaft 11 and the clutch sleeve 12, and the clutch mechanism C is operated by operating the clutch lever 8 to switch between an engaged state and a disengaged state (the operation system will be described in detail. In addition, the cast controller 9 is configured such that the rotation force thereof can change the contact force with respect to the spool shaft 11 to adjust the value of the braking force acting on the spool 5.

As shown in FIGS. 2 to 5, the control case 10 counts the magnetic action of the control device 17 including a microprocessor and a plurality of magnets 18 embedded in the collar-shaped portion of the spool 5. Reed switch type sensors 19 and 19 are installed, and a liquid crystal display 20 that outputs the amount of feeding of the fishing line 4 based on the count signals of the sensors 19 and 19 and a plurality of control switches 21. This reel is provided with an auxiliary drive means for assisting the rotation of the spool 5 to increase the descending speed of the tackle when the clutch mechanism C is operated to disengage the tackle into the sea. , A conductor A formed on the side surface of the spool 5, and a ring-shaped field coil B arranged near the rotation locus of the conductor A. The conductor A is made of an insulating resin sheet material 22. A metal foil 23 made of copper, aluminum or the like is formed on the surface so as to connect a pair of ring-shaped portions 23A, 23A having a spool shaft core and a coaxial core with a plurality of radial conducting portions 23B. The field coil B is supplied with electric power from a battery 26 arranged below the thumb rest 25 via a driver 24 (internalized in the control case 10) driven by a signal from the controller 17. The field coil 23 is configured to generate a rotating magnetic field, and the controller 17 controls the rotation of the spool 5 based on the feedback signals from the sensors 19 and 19. In the field coil B, a plurality of coils 27 are housed in a doughnut-shaped waterproof case 28, and are fitted on the protruding portion 29A of the plate 29 that closes the spool insertion hole so that the air gap with the conductor A is uniform. The battery 26 is housed in a waterproof housing 30 which is integrally formed with a waterproof case 28, and the auxiliary driving means is constructed in the same manner as a squirrel cage induction motor.

In this reel, control is performed as shown in FIG. 6 at the time of inputting a work in process. In this control, signals from the sensors 19 and 19 are first input to determine the rotation direction of the spool 5 (step # 101, (Step # 102), when the clutch mechanism C is disengaged and the spool 5 starts to rotate in the fishing line feeding direction when the work is input, the sensors 19 and 19 sample this rotation speed to determine the change in the work descending speed. , The change characteristic is set, the change characteristic is set as the control target when the predetermined time elapses, the predetermined amount of the fishing line is paid out, and the lowering speed of the work in progress is reduced. The field coil B is driven so that the spool 5 exerts a driving force by feeding back the signal from 19 (steps # 103 to # 106). As described above, the reason why the driving force is not applied to the spool 5 at the same time as the input of the device is that the resistance of water is small in the initial stage of the device input and the device is lowered at a relatively high speed. This is because the backlash is likely to occur even when the ship sways, and in this sampling, the rate of change of the descending speed of the tackle differs depending on the form of the tackle, the weight of the weight, etc., so this change rate is calculated.

The driving force of the auxiliary driving means is set weak enough to generate a slip between the field coil B and the conductor A when the summing is performed, and in this feedback control, it is obtained as described above. The rotation of the spool 5 is assisted at a target speed corresponding to the depth of the tackle based on the rate of change of the tacking descent speed, and at the time of this control, the plurality of coils 27 constituting the field coil B ... A magnetic field is sequentially generated in the direction indicated by arrow F to generate a rotating magnetic field. Incidentally, the driver 24 is provided with an element such as a switching transistor, and when this is energized, a current is sequentially supplied to each of the coils 27 to generate a rotating magnetic field, and a driving force is generated by an induced electromotive force generated in the conductor A. Is configured to get.

Then, when this control is artificially released by operating a predetermined one of the control switches 21, or when the tackle is lowered to the depth of the shelf set at the previous time, the control to the field coil B is performed. The energization is stopped and the control ends (steps # 107 to # 109). The previously set shelf depth refers to the depth of the tackle that caused a crack when the tackle was last thrown in, or the depth of the tackle that was maintained for a relatively long time last time. This depth is set in the memory of the controller (control operation is not described in detail).

Other Embodiments In addition to the above embodiments, the present invention is configured, for example, by forming a conductor A on a surface of a sheet material 22 with a concentric spiral metal foil 23 as shown in FIG. It is also possible. In addition to the above-mentioned structure, this conductor A may be formed in the same manner as a wound-type induction motor by forming a copper wire wound around an iron core on the side surface of the spool, or the spool itself may be made of a metal material. It is also possible to configure and use the spool as the conductor. Further, in the present invention, the control device can be configured by a hard circuit in which a logic gate, a comparator and the like are combined, and the driving means can be arranged on the right side of the spool. Further, the present invention can be applied to a bait casting reel so as to assist the spool rotation during casting of the work in order to increase the throwing distance of the work, and further, the speed of the work during casting. It is also possible to function as a brake to prevent backlash by the action of a rotating magnetic field in the reverse direction when the noise is reduced or by stopping the rotation of the magnetic field.
