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 rotation of a spool in a fishing line feeding direction.

[0002]

[Prior art]

 Conventionally, as a fishing reel configured as described above, there is one disclosed in Japanese Utility Model Laid-Open No. 2-131871. In this conventional example, the fishing line feeding direction of the spool is utilized by utilizing the driving force of an electric motor built in the spool. It is configured to assist in turning to.

[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, 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. The driving force of the electric motor offsets the resistance that acts on the to increase the descending speed of the work in process.

The above-mentioned electric reel has a good aspect that it is possible to increase the descending speed of the work in progress by utilizing the characteristics of the drive system. However, the electric reel is relatively large and configured as a heavy object. Therefore, for fishing that does not target the deep sea too much, there is a demand for a technique for increasing the descending speed of the work in a small reel such as a manual type by assisting the rotation of the spool in the fishing line payout direction as described above. There is. 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.

An object of the present invention is to make a fishing reel that is as small as possible and rationally configured to assist the rotation of a spool with a smooth driving force to increase the descending speed of a work in process.

[0006]

[Means for Solving the Problems]

 A feature of the present invention is that a driven body made of any one of a conductor, a magnetic body, and a permanent magnet is formed on a spool rotatably supported on a reel body, and a rotating magnetic field is applied to the driven body. The reel main body is provided with a field coil that gives a driving force to the spool in the fishing line feeding direction, and a drive system is formed, and an adjusting means for changing the relative distance between the field coil and the driven body is provided. The actions and effects are as follows.

[0007]

[Action]

 If the above features are configured as shown in, for example, FIG. 1 to FIG. 5, when the tackle is lowered into the sea, the clutch mechanism C is disengaged to input the tackle, and the field coil 23 is energized to energize the fishing line. By applying the driving force in the feeding direction, the spool 5 resists the resistance acting from the cast controller 9, the level wind mechanism, etc. by the driving force acting from the field coil 23 to the driven body 22. When the relative distance between the field coil 23 and the driven body 22 is changed by the adjusting means A during this driving, the rotation of the fishing line is accelerated, and the driving force acting on the driven body 22 changes. The drive torque can be adjusted. When the driven body 22 is made of a permanent magnet and the fishing line is delivered without driving the field coil 23, or when the fishing line is wound, an induced current is generated in the field coil 23. At the same time, the braking force acts on the spool 5 due to the interaction between the field coil 23 and the driven body 22, and the relative distance between the field coil 23 and the driven body 22 is adjusted by the adjusting means A. It is possible to set the braking force to any value by changing it. That is, in the present invention, even without using an electric motor having an independent structure, a direct driving force is applied to the spool 5 to accelerate the feeding of the fishing line, and this configuration can be used to suppress backlash. Due to this structure, the resistance acting during the winding operation can be reduced.

[0008]

[Effect of device]

 Therefore, when the fishing reel that assists the rotation of the spool with a smooth driving force to increase the descending speed of the work in progress is relatively small and the driven body is composed of a permanent magnet, backlash is suppressed. It was possible to reduce the operating resistance during winding. In particular, if the driven body is composed of permanent magnets and the field coil is not driven when the work is input, but the field coil and the driven body are brought close to each other, for example, when the ship is shaken significantly, Even in a situation where backlash is likely to occur, it is possible to set a state in which backlash does not occur.

【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 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. The control case 10 is provided all over to configure 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 constituted by the engaging 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 on-state and a disengaged state. (The operating system is not described in detail.) Further, the cast controller 9 is configured to change the contact force to the spool shaft 11 and adjust the value of the braking force acting on the spool 5 by rotating the cast controller 9. There is.

As shown in FIG. 2 to FIG. 5, the control case 10 counts the magnetic action of the control device 17 which is 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.

In this reel, when the clutch mechanism C is disengaged and the tackle is put into the sea, an auxiliary drive means for assisting the rotation of the spool 5 to increase the descending speed of the tackle is provided. As shown in FIG. 1, the driving means is a ring-shaped permanent magnet 22 formed in the collar-shaped portion of the spool 5 and a ring-shaped permanent magnet 22 (an example of a driven body) arranged near the rotation locus of the driven body. The field coil 23 includes a field coil 23, which is driven by a signal from the control device 17 (incorporated in the control case 10) from a battery 26 incorporated in the thumb rest 25. The field coil 23 is supplied with electric power 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. . Further, as the permanent magnet 22, an N pole and an S pole alternately appear along the inner peripheral surface of the ring portion, and an annular member 27 made of a magnetic material such as iron is externally fitted to the outer periphery of the magnetic circuit. Further, the field coil 23 is provided with a plurality of coils 23A ... In its circumferential direction. The field coil 23 is housed in a donut-shaped watertight case 28 and has a spool insertion hole. An electric actuator 31 (an example of adjusting means A) which is slidably fitted onto a guide portion 29A formed to project on a closing plate 29 and transmitted through an operation shaft 30 which is connected to a watertight case 28 of the field coil 23. It is set to an arbitrary position in the spool shaft core direction by the driving force of). As shown in FIG. 5, in this reel, a control of assisting the rotation of the spool 5 in the fishing line payout direction is performed by a signal such as radio waves, infrared rays, ultrasonic waves, etc. from a cordless controller 32 formed independently of the reel body. A control system is configured so that selection can be performed. The controller 32 includes a code conversion unit 32A for inputting a control code, a modulation unit 32B, and a transmission unit 32C. Also, the reel main body side receives as a remote control system. The unit 33A, the demodulation unit 33B, and the code conversion unit 33C are provided.

In this reel, control is performed as shown in FIG. 6 at the time of inputting a work in progress. In this control, signals from the sensors 19 and 19 are first input to determine the rotation direction of the spool 5 (# 101 step, (Step # 102), the clutch mechanism C is disengaged, and when the spool 5 starts to rotate in the fishing line payout direction by inputting a work in progress, the electric field actuator coil 31 is driven by the electric actuator 31 without driving the field coil 23. 23 is brought closer to the driven body 22 side (spool side) to increase the braking force acting between the field coil 23 and the driven body 22 to suppress the occurrence of backlash. Next, when the auxiliary drive is selected by the controller 32 or the control switch 21, a predetermined time elapses, a predetermined amount of fishing line is paid out, and the lowering speed of the work in progress is reduced to a predetermined value. When the above condition is satisfied, the field coil 23 is driven so as to apply a driving force to the spool 5 (steps # 103 to # 106). When the field coil 23 is driven, 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 why the braking force is applied to the spool 5 at the time of inputting the work in progress is that the resistance of water is relatively small in the initial stage of the time when the work is input and the work in progress is descending at a sufficient acceleration. This is because there is little need to assist the delivery and backlash is likely to occur even when the ship sways.

The driving force of the auxiliary driving means is set weak enough to cause a slip between the field coil 23 and the permanent magnet 22 when the summing is performed, and in this control, the driving force of the plurality of field coils 23 is set. The coils 23A ... Are sequentially energized in the direction indicated by arrow F in FIG. 2 to generate a rotating magnetic field. Incidentally, the driver 24 is provided with an element such as a switching transistor, and when it is energized, the direction of current flow is switched so as to obtain a driving force by an attractive force and a repulsive force with respect to the permanent magnet 22. Then, when this control is artificially released by the operation of the controller 32 or the control switch 21, or when the tackle is lowered to the previously set shelf depth, the power supply to the field coil 23 is stopped. Then, the control ends (# 107 step to # 109 step). The depth of the shelf set last time is the depth of the device that caused a crack when the device was last loaded, or the depth of the device that was maintained for a relatively long time last time, or from the outside. This refers to a value that is artificially input, and this depth is set in the memory of the control device (control operation is not described in detail). Further, in this reel, when the fishing line is wound by operating the handle, the electric field actuator 23 is driven to separate the field coil 23 from the driven body 22 so that the braking force from the field coil 23 does not act on the spool 5 (# 110 steps, # 111 steps). The electric actuator 31 is also configured so that it can be set to an arbitrary position by operating a predetermined one of the control switches 21.

[Other Embodiments] The present invention can be implemented as follows in addition to the above embodiments. (A) As shown in FIG. 7, a cam body 36 that rotates around the spool axis with respect to the plate 29 supported by the side case 1 so that the position of the field coil 23 can be adjusted by an artificial operation force of the adjusting means A. By allowing the pin 37 formed on the field coil 23 to engage with the cam groove of the cam body 36, and by providing the 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 is arbitrarily determined by operating the lever 39 connected to the cam body 36. (B) When the rotation of the spool is assisted in the fishing line payout direction by driving the field coil, the torque applied to the spool is automatically increased so as to increase the torque acting on the spool as the amount of fishing line taken out increases. Change the relative distance to the driver. (C) When the spool is rotated in the fishing line winding direction, the field coil is driven in a direction that assists this rotation, and the sensor measures the spool rotation to smooth the spool operation. The field coil is driven by a signal synchronized with the signal. (D) The driven body is composed of a conductor such as copper or aluminum, or a magnetic body such as iron. Incidentally, the driving body configured as described above may be formed in a ring shape as in the embodiment, and a plurality of independent driving pieces may be provided. (E) Further, the field coil may not be formed in a ring shape, but an independent coil may be supported by a plate-shaped frame.
