Description

The present invention relates to an electric reel for smelt fishing in which a spool around which a fishing line is wound is rotationally driven by an electric motor.

In recent years, when hole fishing for smelt or boat fishing for smelt on frozen lakes, fishing is carried out by attaching a short fishing rod to the reel and placing it on a stand instead of holding the fishing rod in the hand all the time. Electric reels are used.
Such an electric reel for smelt fishing, for example, as disclosed in Patent Document 1, has a small electric motor built into the reel body, and the surface of the drive shaft of the electric motor is in direct contact with the side surface of the spool. (Frictional engagement) allows the rotational driving force of the electric motor to be transmitted to the spool by frictional force without using gears or the like.

Generally, when an electric reel for smelt fishing is released, a clutch operating member is operated to separate the frictional engagement between the drive shaft of the electric motor and the side surface of the spool, allowing the spool to rotate freely. and drop the device. Then, when the device falls to a predetermined shelf, by operating the clutch operating member, the drive shaft of the electric motor and the side of the spool are brought into a state of frictional engagement, and when a hit occurs in this state, the electric switch is activated. It is configured to wind up the spool when turned on.
Further, Patent Document 1 discloses a configuration in which a fishing line can be wound up and let out by controlling an electric motor to rotate forward and reverse, and various invitation modes for moving the fishing tackle up and down are proposed.

JP2019-30238

In the conventional electric reel for smelt fishing as described above, if a lure operation (shake operation) is performed while waiting for a hit, the spool may rotate in the opposite direction and the fishing line may be pulled out. This is because the spool is only stopped from rotating in reverse by the magnetic force of the electric motor, so when a large torque is applied from the spool side in the direction of feeding out the fishing line, the drive shaft of the electric motor tends to rotate in reverse. If the spool is engaged and a strong match is made, the spool is likely to rotate in the opposite direction.

Recently, in order to improve fishing results, it has become easier to attach heavy weights to make the bait fall faster, to use longer baits (with more hooks), and to use longer rods to accommodate longer baits. Under such circumstances, if the above-mentioned luring operation or alignment operation is performed, the resistance of the water increases and the spool is likely to rotate in the opposite direction. In this case, increasing the magnetic force of the electric motor will improve the braking force, but power consumption will increase, making it unsuitable for electric reels for smelt that are operated by a small power source (such as a dry battery).

The present invention has been made with a focus on the above-mentioned problem, and is an electric smelt fishing electric motor that can suppress the fishing line from being drawn out when performing a lure operation or a matching operation without increasing the magnetic force of the electric motor. The purpose is to provide reels.

In order to achieve the above object, the electric reel for smelt fishing of the present invention includes a reel body, a spool rotatably supported by the reel body and around which a fishing line is wound, and a spool provided on the reel body, an electric motor having a drive shaft that takes up and drives the fishing line wound around the spool by frictionally engaging with the spool, and a control unit that controls rotation of the drive shaft of the electric motor, The control unit controls the rotation of the drive shaft so as to apply a torque to the extent that the spool does not rotate when the fishing line is wound around the spool in a braking state, except in a winding drive state in which the spool winds the fishing line. It is characterized by making it.

According to the above configuration, the electric motor that rotationally drives the spool through frictional engagement is in a state where the rotation of the drive shaft is controlled to such an extent that the spool does not wind the fishing line, except in the winding drive state, and the spool , a braking force is applied to the rotation in the direction of feeding out the fishing line. For this reason, even if a fishing rod is moved up and down, or a fish is hooked and a fish is hooked, the fishing line is prevented from being unintentionally paid out from the spool. In this case, the magnitude of the braking force applied to the spool is set so that a torque is applied to the extent that the spool does not rotate when the fishing line is wound around the spool, and furthermore, even when the spool is empty, the spool is It may be set to such an extent that it does not rotate.

Further, in order to achieve the above-mentioned object, the electric reel for smelt fishing of the present invention includes a reel body, a spool rotatably supported by the reel body and around which a fishing line is wound, and a spool provided on the reel body. , an electric motor including a drive shaft that takes up and drives the fishing line wound around the spool by frictionally engaging with the spool; The control unit includes a forward rotation drive mode for winding, a reverse rotation drive mode for letting out the fishing line, and a control unit that controls switching to a braking mode that applies a braking force to the spool, and the control unit controls the forward rotation drive mode, Further, the device is characterized in that the device is switched to the braking mode other than the reverse drive mode in which the fishing line is let out.

According to the above configuration, when the electric motor that rotationally drives the spool through frictional engagement is in a mode other than the drive mode (forward rotation drive mode, reverse rotation drive mode), the electric motor is placed in the braking mode that applies a braking force to the spool. By switching, the fishing line is prevented from being unintentionally paid out from the spool even if the fishing rod is moved up and down, or when a fishing rod is hooked and a fish is hooked, the fishing line is prevented from being unintentionally paid out.

According to the present invention, it is possible to obtain an electric reel for smelt fishing that can suppress the reeling out of the fishing line when performing a lure operation or a matching operation without increasing the magnetic force of the electric motor.

The electric reel according to this embodiment transmits power (rotates the spool in the fishing line winding direction) by frictionally contacting the side surface of the spool with the drive shaft of the electric motor perpendicular to the rotation axis of the spool, for example. The spool is configured to be in a state in which it can rotate freely by mechanically displacing the electric motor to release (separate) the frictional contact between the two. In this case, the rotational state of the transmission of the rotational driving force to the spool is controlled by controlling the voltage applied to the electric motor without using gears to change the speed.

As shown in FIGS. 1 to 3, the electric reel 4 includes a reel body 5. As shown in FIGS. The reel main body 5 has a casing 6 forming an outer shell thereof. The housing 6 is made of a synthetic resin material such as ABS resin or polycarbonate.

The housing 6 is a slightly curved vertically elongated box (long in the front-rear direction), and has a size that allows an angler to grasp it with his or her right or left hand (right hand in Figure 2), as shown in Figure 2. . As shown in FIG. 3, the housing 6 includes a lower case 7 and a top cover 8.

The top cover 8 is fixed to the lower case 7 by means such as screwing or fitting, and defines a motor accommodating chamber for accommodating the electric motor 44 between the top cover 8 and the lower case 7. Further, inside the reel body 5, in the lower case 7 in this embodiment, a power source 52 (for example, a dry battery, a rechargeable battery, etc., and in this embodiment, for supplying power to the electric motor 44 and the liquid crystal display device 90) is installed. An internal power supply housing 71 is provided that defines a storage section S that can removably accommodate a battery (Using two AAA alkaline batteries in parallel).

Note that the reel body 5 has a housing part S of the internal power supply housing 71 (in this embodiment, an opening of the lower case 7 for exposing the electric motor 44 and the like as a whole including the housing part S) to the outside. A cover member 77 for closing is detachably attached.

The housing 6 has a pair of legs 16. The legs 16 are made of a rubber-like elastic material that is softer than the housing 6, for example. The legs 16 are fixed to the bottom wall of the lower case 7 and spaced apart from each other in the left-right direction of the reel body 5. The legs 16 function as a grounding portion that comes into contact with the top surface of a fishing platform installed on a frozen lake surface, for example, when the reel body 5 is placed on the platform.

A support stand 26 made of synthetic resin is fixed to the front end of the housing 6 by screws or the like, and this support stand 26 has a rod receiving part 27 as a rod mounting part to which a fishing rod 40 can be attached, and a spool receiving part. 28.

The rod receiving portion 27 is located at the center of the front end of the housing 6 along the left-right direction (width direction perpendicular to the front-back direction). The rod receiving portion 27 has a support hole 29 that opens toward the front of the housing 6 and supports the fishing line guide 30. The fishing line guide 30 is rotatable between a standby position in which it stands vertically so as to protrude above the rod holder 27 and an operating position in which it falls down toward the rear of the housing 6 from this standby position, and is normally in the standby position. held in position. Further, the spool receiving portion 28 of the support stand 26 is arranged horizontally below the opening 21 of the top cover 8.

As shown in FIG. 3, a spool shaft 33 is supported on the shaft support 13 on the bottom wall of the lower case 7. The spool shaft 33 stands vertically from the bottom wall of the lower case 7, passes through the spool receiving part 28, and projects above the spool receiving part 28.

A spool 34 made of synthetic resin or metal is rotatably supported on the upper part of the spool shaft 33. The spool 34 is located in the front part of the reel body 5 at the center in the left-right direction on the front side of the upper surface of the reel body 5.
Note that a liquid crystal display device 90 is provided immediately behind the spool 34 and located on the upper surface of the housing 6 (above the top cover 8). The liquid crystal display device 90 displays various information such as, for example, the amount of payout of the device (water depth counter), setting status of modes related to different inviting operations, winding speed, and alarm.

The spool 34 has a fishing line winding trunk 36 around which a fishing line is wound, and a pair of flanges 37a, 37b, and rotates around a vertical spool shaft 33. The flanges 37a and 37b are disk-shaped and coaxial with the fishing line winding trunk 36, and face each other in the vertical direction with the fishing line winding trunk 36 in between. In this case, the lower flange 37b is placed on the upper surface of the spool receiving portion 28.

The spool shaft 33 coaxially passes through the fishing line winding trunk 36 and projects above the upper flange 37a. A cap nut 38 is screwed into the upper end of the spool shaft 33. The cap nut 38 sandwiches the spool 34 between the cap nut 38 and the spool receiving part 28, so that the spool 34 is rotatably supported at the front part of the reel body 5. Note that the spool 34 is located inside the opening 21 of the top cover 8.

As shown in FIG. 3, a fishing rod 40 is fitted into the support hole 29 of the rod receiving portion 27. The structure of the fishing rod 40 to be fitted is not particularly limited in terms of length, material, etc., and in the fitted state it projects horizontally forward from the front end of the reel body 5.

A plurality of fishing line guides (not shown) are attached to the outer peripheral surface of the fishing rod 40. These fishing line guides are provided in a line with intervals in the longitudinal direction of the fishing rod 40. The fishing line (not shown) let out from the spool 34 is guided from the fishing line guide 30 of the reel body 5 to the tip of the fishing rod 40 via the fishing line guide of the fishing rod 40, and then is opened from the tip of the fishing rod 40 onto the surface of a lake, for example. They are led into the water through a hole.

The electric motor 44 installed in a motor housing chamber formed between the top cover 8 and the lower case 7 includes a motor housing (not shown) that accommodates a stator and a rotor, and a drive shaft that protrudes from the front end of the motor housing. (output shaft) 46. The electric motor 44 is installed behind the spool 34 in a horizontal position with the drive shaft 46 along the front-rear direction of the housing 6 .

The drive shaft 46 of the electric motor 44 is located immediately after the spool shaft 33 and maintains a positional relationship perpendicular to the spool shaft 33. The front end of the drive shaft 46 is located below the lower flange 37b of the spool 34.

A cylindrical torque transmission member 47 is attached to the outer periphery of the drive shaft 46 . The torque transmission member 47 is formed of, for example, a synthetic resin material or a rubber-like elastic body that is softer than the spool 34. In the state shown in FIG. 3, the outer peripheral surface of the torque transmission member 47 is frictionally engaged with the lower surface of the lower flange 37b of the spool 34, and the rotational driving force of the electric motor 44 is transferred to the drive shaft 46 (torque It is configured to transmit to the spool 34 via a transmission member 47).

The motor housing of the electric motor 44 (therefore, the electric motor 44) has a pivot shaft (not shown) as a fulcrum, and has a first horizontal position shown in FIG. 3 and a second position (not shown) in which it is tilted forward and downward. It is possible to rotate between. In the first position, as shown in FIG. 3, the drive shaft 46 of the electric motor 44 extends horizontally along the front-rear direction of the housing 6, and the outer peripheral surface of the torque transmission member 47 is connected to the lower flange of the spool 34. It comes into contact (frictional contact) with the lower surface of 37b. By abutting in this manner, frictional resistance is applied to the abutting portion between the flange 37b and the torque transmission member 47, and the drive shaft 46 of the electric motor 44 and the spool 34 are mechanically connected. As a result, the rotational driving force of the electric motor 44 is transmitted to the spool 34 via the drive shaft 46 and the torque transmission member 47 due to frictional resistance.

On the other hand, in the second position, the drive shaft 46 of the electric motor 44 is tilted forward, and the outer peripheral surface of the torque transmission member 47 is separated from the lower surface of the lower flange 37b of the spool 34. As a result, the mechanical connection between the drive shaft 46 of the electric motor 44 and the spool 34 is released, frictional resistance is no longer applied between the torque transmission member 47 and the spool 34, and the spool 34 is in a state where it can freely rotate. becomes.

Note that the electric motor 44 is always elastically biased toward the first position via a tension coil spring (not shown). Therefore, as long as the motor 44 is in the first position, the outer peripheral surface of the torque transmission member 47 is elastically pressed against the lower surface of the lower flange 37b of the spool 34.

Switching between the first position and the second position of the electric motor 44 (motor housing) is performed, for example, by an operating body (clutch operating body) 22 provided protruding from the top cover 8. The lower end of the operating body 22 faces the torque transmitting member 47, and when pressed downward, the operating body 22 moves the drive shaft 46 of the electric motor 44 downward (to the second position) together with the torque transmitting member 47. to press. As a result, the mechanical connection between the drive shaft 46 of the electric motor 44 and the spool 34 is released. Further, when the pressing operation force of the operating body 22 is released, the electric motor 44 returns to the first position due to the biasing force of the above-mentioned tension coil spring.

That is, the operating body 22 is a clutch mechanism that switches between a state in which the drive shaft 46 of the electric motor 44 and the spool 34 are mechanically connected (power transmission state) and a state in which these connections are released (power transmission cutoff state). By turning off the clutch mechanism using the operating body 22, the device can be quickly dropped onto a predetermined shelf.

The housing 6 is provided with an operation switch (a plurality of operation switches are collectively referred to as an operation member) that can turn the device ON/OFF, drive the electric motor 44, set a mode during actual fishing, etc. In this embodiment, operation switches 70 and 72 are provided on the left and right side walls of the housing 6, respectively, and operation switches 82 and 84 are provided immediately behind the liquid crystal display device 90 (on the top surface of the housing 6). (The functions of each operation switch will be described later). Further, inside the housing 6, a control unit (IC module) 100 that stores programs for controlling the display of various information on the liquid crystal display device 90 and controlling the drive of the electric motor is housed in a waterproof case (not shown). It is installed in The control unit 100 receives the operation signal from the above-mentioned operation member, and controls forward/reverse rotation of the electric motor 44 via a motor drive circuit 110 that controls the drive of the electric motor 44 according to a predetermined operation program. do.

The electric motor 44 is rotationally driven by applying a voltage supplied from the power source 52 to the motor drive circuit 110, and the voltage applied to the electric motor 44 is controlled by the control unit 100 in accordance with the operation of the operating member. is controlled variably. For example, in this embodiment, the winding speed and unwinding speed of the spool are variably controlled (the rotational speed of the spool is variably controlled), and in this embodiment, when the device is put into an operating state (ON state) by the operating member, , the rotation of the drive shaft 46 is controlled so that the electric motor 44 is always rotated in the fishing line winding direction (hereinafter referred to as (referred to as a low-speed winding drive state).

That is, in this embodiment, the control unit 100 controls the drive shaft 46 of the electric motor 44 to always be in the low-speed winding drive state, except in the winding drive state in which the spool winds the fishing line. The spool is always in a braking state to prevent it from inadvertently reversing. In this case, the rotational force (rotational speed) of the drive shaft 46 is sufficient as long as it does not rotate the spool 34 in the winding direction when the fishing line is wound around the spool 34, and the rotational force (rotational speed) of the drive shaft 46 is sufficient as long as it does not rotate the spool 34 in the winding direction when the fishing line is wound around the spool 34. It is set to prevent careless winding. In particular, in order to ensure that the fishing line is not wound reliably, even when no fishing line is wound around the spool 34 (the spool is empty), a torque is applied to the extent that the spool does not rotate. It is preferable to control (control to a braking state that prevents the fishing line from being wound carelessly even if the amount of winding of the fishing line is small).
In this embodiment, the electric motor 44 is configured to be driven in reverse according to the invitation mode setting, so that even during this reverse rotation, the above-described low-speed winding drive state is released. There is.

As described above, the electric motor 44 of this embodiment not only rotates in the forward direction, but also drives in the forward/reverse direction according to the mode setting so that various types of bait motions (vertical movement of the trick) are possible. is configured to be Although detailed description of the modes related to the inviting operation will be omitted here, the control unit 100 may, for example, repeat forward and reverse rotation of the electric motor after the device is thrown in, or repeat forward and reverse rotation intermittently. A program is stored that executes a mode in which the mechanism is moved up and down in various patterns, and the mode is selected according to the user's preference, and the electric motor 44 is controlled to rotate forward or reverse depending on the selected mode. .

The motor drive circuit 110 that controls the drive of the electric motor 44 by the control unit 100 can be configured with an H-bridge control circuit as shown in FIG. 5, for example. In the control circuit shown in the figure, when transistors 110a and 110d are turned on at the same time, a current flows like D1, and it is possible to drive the electric motor 44 in normal rotation (normal rotation mode). Furthermore, when the transistors 110b and 110c are turned on at the same time, a current flows like D2, and it is possible to drive the electric motor 44 in the reverse direction (reverse mode). Note that when the power is turned off, the transistors 110a to 110d are turned off, and the drive shaft 46 is in a free state (free mode).

Next, the functions of the above-mentioned operation members (operation switches 70, 72 and 82, 84) will be explained.

The operation switches 70 and 72 have the same function, and can be operated simultaneously with two fingers (for example, thumb and index finger) of the hand holding the reel body 5, as shown in FIG. They are provided on the left and right sides respectively.
By pressing and holding either one of the operation switches 70, 72, the electric motor 44 is continuously driven. Furthermore, the electric motor 44 is driven in increments (chopped winding) by pressing either one of the operation switches 70, 72 for a momentary short period of time without pressing it for a long time.

The operation switch 82 has a function as an ON/OFF switch of the device and a function to adjust the driving speed of the electric motor 44. For example, by pressing the operation switch 82 for a long time, it is turned on/off, and by pressing it intermittently in the ON state, it is possible to adjust the speed (change the speed in 10 steps, for example). Note that the drive speed stages are displayed on the liquid crystal display device 90.

The operation switch 84 has a shelf setting function that sets the shelf when the bait is on a predetermined shelf, and an invitation mode setting function that realizes various vertical movements of the bait (continuous or intermittent fishing line winding of the electric motor 44). It has a function (rotational drive in a specific pattern in the taking direction and/or steering direction) and a function to stop the hoisted device at a preferable position (gunwale stop function). These can be changed to the state desired by the user by pressing the operation switch 84 for a long time or multiple times (for example, pressing it twice), and the set functions are displayed on the liquid crystal display device 90.

According to the electric reel configured as described above, the electric motor 44 that rotationally drives the spool 34 through frictional engagement is always set to the low-speed winding drive state, except in the winding drive state and the feeding drive state, and the spool 34 is in a state where a braking force is applied to the rotation in the fishing line payout direction. Therefore, in such a situation, even if you perform an invitation operation such as moving the fishing rod up and down (in this case, a manual jerking operation that does not use an electric motor), or a fish hooks and you perform an adjustment operation, the spool 34 This prevents the fishing line from being carelessly let out.

In particular, even if you attach a heavy weight to the device, attach a long device (with a large number of needles), or use a long rod compatible with a long device, and perform the above-mentioned inviting and matching operations, the spool will not move. It becomes difficult to reverse rotation. That is, the braking force for the spool can be improved without increasing the magnetic force of the electric motor 44 (without increasing power consumption).

In the above-described embodiment, the electric motor 44 was configured to perform forward rotation drive and reverse rotation drive according to the invitation mode, but without providing such an invitation mode function, it only performs winding drive (forward rotation drive). It is also possible to have a configuration that performs only Furthermore, in addition to setting the above-mentioned invitation mode, for feeding out the fishing line (dropping the fishing tackle), the electric motor 44 is configured to be driven in reverse by a user's operation (operation of an operation switch) in a manual mode. Alternatively, it may be performed by operating a clutch mechanism.
Furthermore, the above-mentioned low-speed take-up drive state (low-speed drive of the electric motor) does not need to be performed all the time, but only when the bait is in the water after being fed out (for example, when the bait is dropped by a water depth meter). The device may be activated when the device detects the falling object and stops falling. In such a configuration, the electric motor 44 enters the low-speed winding drive state only when necessary, so power consumption can be reduced.

Next, a second embodiment of the present invention will be described.
In the embodiment described above, the braking force is applied to the spool 34 by constantly putting the electric motor 44 in the low-speed winding drive state. Also good.

For example, in the embodiment described above, the control unit 100 controls the current flowing through the motor drive circuit 110 to control the rotation of the electric motor 44 to be in the forward rotation mode, reverse rotation mode, and free mode. In the motor drive circuit 110, when transistors 110c and 110d are turned on at the same time, it is possible to put the drive of the electric motor into a braking state (braking mode).

That is, in the control program of the control unit 100, when the electric motor 44 is in a normal rotation drive state (normal rotation mode), a reverse rotation drive state (reverse rotation mode), and other than the free mode, the transistors 110c and 110d are simultaneously turned on and the electric motor 44 is turned on. By changing the drive of the motor 44 to a braking state, it is also possible to suppress the rotation of the spool 34 in the feeding direction during a guiding operation or a matching operation.

Furthermore, in a configuration in which the electric motor 44 is driven in reverse, a mechanical clutch mechanism may be eliminated. Further, the timing of changing to the braking mode described above may be changed after the reverse rotation of the electric motor 44 has stopped, or after the device has fallen and the stoppage of the device has been detected.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be implemented with various modifications without departing from the gist thereof. For example, the functions and arrangement positions of the operating members (operating switches) can be changed as appropriate.

Further, the braking force acting on the spool described above may be set to a specific value, but the magnitude of the braking force may be adjusted by a user's operation. For example, by variably controlling the voltage applied to the electric motor according to the user's settings and adjusting the amount of rotation of the drive shaft in the braking state, the amount of torque that prevents the spool from rotating inadvertently can be adjusted. You can also do it. In other words, the braking force may be arbitrarily adjusted depending on the weight of the device or the depth of the shelf.
