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, 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, a drive of an electric motor built in a spool for the purpose of driving a fishing line in a winding direction. It is configured to assist the rotation of the spool in the fishing line payout direction by using force.

[0003]

[Problems to be solved by the device]

 Here, considering the introduction of the 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 etc. The driving force of the electric motor cancels out the resistance that acts on the to increase the descending speed of the in-process.

The above-described conventional electric reel has a good aspect that the characteristics of the drive system can be used to increase the descending speed of the work in progress, but the electric reel is relatively large and heavy. Therefore, for fishing that does not target deep seas, there is a demand for a technique for assisting the rotation of the spool in the fishing line payout direction and increasing the in-process descending speed in a small reel such as a manual type, as described above. It is rare. In squid fishing, especially in squid, the captain detects a group of squid with a fish finder and then inputs the tackle all at once as instructed by the captain. However, 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.

Therefore, it is conceivable to provide a coil on the reel body side and form means for driving the spool by receiving the action of the magnetic force from the coil with respect to the spool to make the drive system compact. In the drive system, it is important to make the distance between the coil and the means for receiving the magnetic force (air gap) relatively small and uniform as much as possible in order to obtain high torque with small electric power and smooth rotation. A technology that can easily improve accuracy is desired. An object of the present invention is to make the fishing reel as small as possible in order to increase the descending speed of the work in progress by assisting the rotation of the spool with a smooth driving force.

[0006]

[Means for Solving the Problems]

 The feature of the present invention is that a driven body made of an electric conductor, a magnetic body or 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 ring-shaped field coil that gives a driving force to the spool in the fishing line feeding direction, and a drive system is formed, and the ring coil has an inner peripheral surface or an outer peripheral surface. The reel body is provided with a positioning portion that fits and holds the field coil. The action and effect are as follows.

[0007]

[Action]

 If the above features are configured as shown in FIGS. 1 to 3, for example, when lowering the tackle into the sea, the clutch mechanism C is operated to turn on the tackle to energize the field coil 23. By driving the spool 23 in the fishing line 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. The rotation of the fishing line in the feeding direction is promoted. Further, in this type of reel, the spool 5 is supported by the bearing or the like with a relatively high axial accuracy with respect to the reel body 1, and the ring-shaped field coil 23 is positioned in the reel body 1. By fitting and supporting the portion 29A, the relative distance between the driven body 22 and the field coil 23 formed in the spool 5 can be made uniform even if the distance (air gap) is relatively small. It can be maintained.

That is, in the present invention, since the rotating force is directly applied to the spool 5 by the driven body 22 and the field coil 23, the structure for this drive is different from the structure provided with an electric motor or the like. The reel can be placed in a relatively small space, and the drive speed can be adjusted by electrical control without performing mechanical gear shifting to increase the lowering speed of the work in progress and to The field coil 23 can be mounted with high accuracy simply by fitting the field coil 23 into the positioning portion 29A during assembly.

[0009]

[Effect of the device]

 Therefore, the fishing reel for supporting the rotation of the spool with a small amount of electric power and a smooth driving force to increase the descending speed of the work can be constructed in a small size. In particular, when the field coil is formed in a watertight type, even if seawater may enter the reel body, there is no effect such as electric leakage and short circuit.

[0010]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 5, between the left and right side cases 1 and 1 forming the reel body, a level wind mechanism that reciprocally drives the thread guide tool 3 in the left and right direction by rotation of a screw shaft 2, and a fishing line 4. Spools 5 for winding up each are arranged, 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, and the left and right side cases 1 and 1 are provided on top of each other. The control case 10 is provided all over to form a fishing reel for use in boat fishing.

A spool shaft 11 that rotates integrally with the spool 5 is supported on the left and right side cases 1, 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 the handle 11 and fitted to a handle shaft 13 connected to the handle 6, and 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 switching the clutch lever 8 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 with respect 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.

The control case 10 includes a control device 17 including a microprocessor, and reed switch type sensors 19 and 19 for counting the magnetic action of a plurality of magnets 18 embedded in the collar portion of the spool 5. Further, a liquid crystal display 20 for outputting the amount of feeding of the fishing line 4 based on the count signals of the sensors 19, 19 and a plurality of control switches 21.

In this reel, when the clutch mechanism C is operated to disengage the tackle into the sea, the rotation of the spool 5 is assisted to increase the descending speed of the tackle, and the spool is operated by the handle operation. When the spool 5 is driven in the fishing line winding direction, the spool 5 is provided with an auxiliary driving means for applying a rotational driving force to perform a smooth winding operation. The auxiliary driving means is a ring-shaped member formed on the collar-shaped portion of the spool 5. It is composed of a permanent magnet 22 and a ring-shaped field coil 23 arranged in the vicinity of the rotation locus of the permanent magnet 22 (an example of a driven body). The electric power from the battery 26 stored in the thumb rest 25 is supplied through the driver 24 (internalized in the control case 10) driven by the signal of the field coil 23 to generate the rotating magnetic field in the field coil 23. The control device 17 controls the rotation of the spool 5 based on the feedback signals from the sensors 19 and 19. The permanent magnet 22 uses N poles and S poles alternately appearing 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 the circumferential direction thereof, and the field coil 23 is housed in a doughnut-shaped watertight case 28 and has a spool insertion hole. It is fitted onto the positioning portion 29A formed to project on the closing plate 29 to keep the air gap with the permanent magnet 22 uniform at a small interval, and moreover, the axis of the field coil 23 and the axis of the spool shaft 11 are aligned. Match.

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, # 102 step), the clutch mechanism C is disengaged and operated, and when the spool is started to rotate in the fishing line feeding direction, the rotation speed is sampled by the sensors 19 and 19. The change characteristic is set and the change characteristic is set, and this change characteristic is set as a control target when a predetermined time elapses, a predetermined amount of fishing line is fed, or when the work descending speed is reduced to a predetermined value. In addition, the field coil 23 is driven so as to apply a driving force to the spool 5 in a form of feeding back signals from the sensors 19 and 19 (steps # 103 to # 1). 05 step). 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 work in progress is that the resistance of water is relatively small in the initial stage when the work is input, and the work is descending at a sufficient acceleration speed. Therefore, it is not necessary to assist the feeding, and backlash is likely to occur even when the ship is shaken.In addition, in this sampling, the descending speed of the mechanism depends on the mechanism of the mechanism and the weight of the weight. Since the rate of change is different, this is the process of obtaining this rate of change.

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 feedback control, it is obtained as described above. The rotation speed 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. At the time of this control, the plurality of coils 23A ... A rotating magnetic field is generated by sequentially energizing in the direction indicated by arrow F in FIG. Incidentally, the driver 24 is provided with an element such as a switching transistor, and when it is energized, the current direction is switched so as to obtain the driving force by the attractive force and the repulsive force with respect to the permanent magnet 22.

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 previously, the field coil 23 is controlled. The energization is stopped and the control ends (# 106 step to # 108 step). The depth of the shelf set last time is the depth of the device that caused a crack when the device was last put in, 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 rotation speed of the spool 5 is determined based on the signals from the sensors 19 and 19 (# 109 step, # 110 step). Control for driving the field coil 23 so as to generate a rotating magnetic field in the field coil 23 (# 110 step, # 111 step), and changing this drive following the fluctuation of the winding speed of the spool 5. Is configured to do. In this way, the reel is constructed so that when the spool 5 rotates, the field coil 23 is always driven to automatically assist the rotation of the spool 5.
