By the way, in the electric reel for fishing that feeds the fishing thread from the spool by the reverse rotation drive of the drive motor in this way, when the feeding speed (release speed) of the fishing thread by the drive motor greatly exceeds the falling speed of the device, the fishing thread indulges and loosens. The so-called backlash phenomenon may occur and the fishing thread may become entangled or entangled.

On the other hand, if the release speed of the fishing thread by the drive motor is lower than the falling speed of the tackle, the time required for the tackle to fall becomes longer and the fishing result also drops (the speed at which the fishing thread is released from the spool by the drive motor can be increased. Can not).

Therefore, in order to avoid such inconvenience, it is necessary to synchronize the release speed of the fishing thread by the drive motor with the falling speed of the tackle. However, in the conventional electric reel for fishing, the user (fisherman) is, for example, the motor. By adjusting the output of the drive motor with the output adjustment unit, these speeds are synchronized with each other, and it has been difficult to respond well to changes in the usage environment (water depth, tide flow, etc.).

The present invention has been made by paying attention to the above-mentioned problems, and is for fishing that can realize a high speed of release of fishing thread from a spool by a drive motor (high-speed drop of a device) without causing a backlash phenomenon. The purpose is to provide an electric reel.

In order to achieve the above object, the present invention is an electric reel for fishing, in which the spool is rotated in the forward and reverse directions by the forward and reverse rotation drive of the drive motor to wind and / or feed the fishing thread around the spool. A motor output adjusting unit for adjusting the motor output of the motor, a tension detecting unit for detecting the tension of the fishing thread, and a voltage corresponding to a signal input from the motor output adjusting unit are supplied to the drive motor. An input unit for inputting a mode switching signal for switching between a normal mode and a high-speed drop mode in which the voltage supplied to the drive motor is adjusted based on the tension of the fishing thread when the drive motor is driven in the reverse rotation, and the tension. The control unit has a control unit that controls the operation of the drive motor by receiving a detection signal from the detection unit, a mode switching signal from the input unit, and an input signal from the motor output adjustment unit. When the normal mode is set by the mode switching signal, a voltage corresponding to the signal input from the motor output adjusting unit is supplied to the drive motor, and the mode switching signal is set to the high-speed drop mode. Then, when the tension detected by the tension detection unit falls below the first threshold value during the reverse rotation drive of the drive motor for feeding the fishing thread, the voltage corresponding to the signal input from the motor output adjustment unit is increased. A low voltage is supplied to the drive motor, and when the tension detected by the tension detection unit exceeds a second threshold value larger than the first threshold value, it corresponds to a signal input from the motor output adjustment unit. It is characterized in that a voltage higher than the voltage to be applied is supplied to the drive motor.

Further, the present invention is an electric reel for fishing in which the spool is rotated in the forward and reverse directions by driving the drive motor in the forward and reverse directions to wind and / or feed the fishing thread on the spool, and the motor output of the drive motor is adjusted. A motor output adjusting unit for detecting the tension of the fishing thread, a tension detecting unit for detecting the tension of the fishing thread, a normal mode in which a voltage corresponding to a signal input from the motor output adjusting unit is supplied to the driving motor, and the driving. An input unit for inputting a mode switching signal for switching between a high-speed drop mode in which the voltage supplied to the drive motor is adjusted based on the tension of the fishing thread when the motor is driven in the reverse rotation, and a detection signal from the tension detection unit. The mode switching signal from the input unit and the input signal from the motor output adjusting unit are received, and the detection speed from the speed detection unit that detects the rotation speed of the spool and the detection speed from the motor output adjusting unit are input. It has a control unit that determines the voltage to be supplied to the drive motor based on the target speed and controls the operation of the drive motor, and the control unit is set to the normal mode by the mode switching signal. Then, a voltage corresponding to the signal input from the motor output adjusting unit is supplied to the drive motor, and when the high-speed drop mode is set by the mode switching signal, the reverse of the drive motor that feeds the fishing thread. During rotation drive, the target speed is lowered when the tension detected by the tension detection unit is lower than the first threshold value, and the tension detected by the tension detection unit is larger than the first threshold value. It is characterized in that the target speed is increased when the speed exceeds.

According to the above configuration, when the high-speed drop mode is set, when the drive motor for feeding the fishing thread is driven in the reverse rotation, and the tension detected by the tension detection unit is lower than the first threshold value (for example, the fishing thread by the drive motor). When the discharge speed of the device greatly exceeds the falling speed of the device), a voltage lower than the voltage corresponding to the signal input from the motor output regulator is supplied to the drive motor (or the target speed is lowered) (that is, the target speed is lowered). (In order to reduce the discharge speed of the fishing thread by the drive motor to match the falling speed of the device), it is possible to prevent the occurrence of the so-called backlash phenomenon in which the fishing thread indulges and loosens, and it is possible to avoid the situation where the fishing thread is entangled or entangled.

Further, according to the above configuration, when the high-speed drop mode is set, the tension detected by the tension detection unit is set to a second threshold value larger than the first threshold value when the drive motor for feeding the fishing thread is driven in the reverse rotation. When it exceeds (for example, when the discharge speed of the fishing thread by the drive motor is lower than the falling speed of the device), a voltage higher than the voltage corresponding to the signal input from the motor output adjusting unit is supplied to the drive motor (or the target). Because the speed can be increased (that is, to increase the release speed of the fishing thread by the drive motor to match the falling speed of the device), it is possible to realize the fishing thread release speed according to the falling speed of the device without hindering the falling of the device. Can encourage high-speed fall.

That is, according to the above configuration, it is not necessary for the user (fisherman) to perform troublesome and difficult operations such as synchronizing the release speed of the fishing thread by the drive motor and the gimmick fall speed, and the change in the usage environment (water depth and tide flow). Etc.), etc., can be realized without backlash.

According to the present invention, it is possible to obtain an electric reel for fishing that can realize a high speed of release of fishing thread from a spool by a drive motor (high-speed drop of a device) without causing a backlash phenomenon.

Hereinafter, an embodiment of an electric reel for fishing according to the present invention will be specifically described with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the fishing electric reel 1 according to the present embodiment is rotated in the forward and reverse directions by the drive motor 2 and the forward / reverse rotation drive of the drive motor 2 to rotate the fishing thread (FIGS. 1 and 2). A tubular spool 4 for winding and / or unwinding) and a reel body 6 for accommodating and holding the spool 4 are provided. In this case, the spool 4 is rotatably supported by the reel body 6 via a bearing (not shown), and the drive motor 2 is housed in the motor housing, for example, inside the cylindrical spool 4. It may be supported and fixed so as not to rotate, and is preferably supplied by a power source P detachably mounted on the reel body 6.

Further, the drive motor 2 and the spool 4 are connected to each other by a power transmission mechanism (power transmission path) 10 so as to be able to transmit power. In this case, the power transmission mechanism 10 may have a bidirectional clutch that transmits the rotation of the drive motor 2 to the spool 4 side but does not transmit the rotation of the spool 4 to the drive motor 2 side, or from the drive motor 2. A deceleration mechanism may be provided which decelerates the power of the motor and transmits the power to the spool 4.

The electric reel 1 for fishing according to the present embodiment is provided with a level wind device 40 for winding the fishing thread in parallel with the spool 4. The level wind device 40 is configured such that when the drive motor 2 is rotationally driven, the guide body 42 for inserting the fishing thread fed from the spool 4 reciprocates to the left and right in conjunction with the rotation driving, and the fishing thread is wound up. It has a function of evenly winding the fishing thread around the spool 4 in accordance with the operation.

Further, as shown in FIG. 2, the electric reel 1 for fishing according to the present embodiment has a motor output adjusting unit 22 for adjusting the motor output of the drive motor 2 (for example, a hand holding the reel body 6). A lever member or dial member provided on the reel body 6 at a position that can be operated with a finger (not shown in FIG. 1), a tension sensor 20 as a tension detection unit for detecting the tension of the fishing thread, and a motor. The voltage supplied to the drive motor 2 is adjusted based on the tension of the fishing thread during the reverse rotation drive of the drive motor 2 and the normal mode in which the voltage corresponding to the signal input from the output adjusting unit 22 is supplied to the drive motor 2. A mode input unit 16 for inputting a mode switching signal for switching between the high-speed drop mode, a detection signal from the tension sensor 20, a mode switching signal from the mode input unit 16, and an input signal from the motor output adjusting unit 22. A control device 15 having a control unit 18 that controls the operation of the drive motor 2 in response to the above is provided.

Here, examples of the tension sensor 20 include those using a strain gauge that converts the strain of a member that receives tension into a change in electrical resistance. In addition, a method that uses a piezoelectric element that detects the pressure applied to a member that receives tension by converting it into a voltage, a method that detects the position of equilibrium between a linear spring and tension with a position sensor, and a method that applies tension to a ferromagnetic material. It is conceivable to use a magnetostrictive sensor that detects a change in the magnetic permeability due to the magnetostrictive effect that occurs at that time. Further, the mode input unit 16 includes, for example, a mode operation switch attached to the reel body 6. The mode operation switch may be attached to an operation unit configured separately from the fishing electric reel 1, or the operation unit and the fishing electric reel 1 may perform wireless communication. Further, not only the switch operation but also known input methods such as voice input and motion input can be used. Further, the mode input unit 16 may use a method of automatically switching the mode when a predetermined condition is detected by the microcomputer and various detection devices, in addition to switching according to the intention of the user.

When the control unit 18 of the control device 15 is set to the normal mode by the mode switching signal, the control unit 18 supplies a voltage corresponding to the signal input from the motor output adjusting unit 22 to the drive motor 2 and also uses the mode switching signal. When the high-speed drop mode is set, the tension T detected by the tension sensor 20 is input from the motor output adjusting unit 22 when the tension T detected by the tension sensor 20 is lower than the first threshold value T1 during the reverse rotation drive of the drive motor 2 for feeding the fishing thread. When a voltage lower than the voltage corresponding to the signal is supplied to the drive motor 2 and the tension T detected by the tension sensor 20 exceeds the second threshold T1 which is larger than the first threshold T1, the motor output adjusting unit A voltage higher than the voltage corresponding to the signal input from 22 is supplied to the drive motor 2. In this case, the first threshold value T1 is preferably in the range of, for example, 5 gf to 100 gf, and the second threshold value T2 is preferably in the range of 1.5 to 10 times, for example, T1. If the value of the first threshold value T1 is too large, the falling speed cannot be sufficiently increased. Further, if the value of the first threshold value T1 is too small, there are problems that the risk of thread entanglement increases when a disturbance occurs, the required accuracy of the tension sensor increases, and the cost increases.

Further, the control unit 18 may automatically switch to the normal mode when the fishing thread is wound. At the time of winding, the risk of yarn entanglement does not increase even if the rotation speed of the drive motor 2 is increased. Therefore, the fastest winding is when the voltage applied to the drive motor 2 is maximized. Because it is self-evident. Therefore, there is little need for a high-speed drop mode during winding. On the other hand, at the time of feeding the fishing thread, as described above, if the rotation speed of the drive motor 2 is too fast, thread entanglement occurs, so that there is an optimum speed for feeding the fishing thread at the fastest speed. Depending on the purpose of the user, it is preferable to be able to switch between a high-speed drop mode for feeding the fishing thread fastest and a normal mode for feeding according to the lever operation.

Further, the high-speed drop mode and the normal mode may be continuously switched according to the operation of the motor output adjusting unit 22. An example is shown in FIG. The motor output adjusting unit 22 of FIG. 6 is of a type that adjusts the output by rotating the lever, and the rotatable range of the lever is ± 150 °. When the lever is + 150 ° to + 90 °, it is in the high-speed drop mode, when it is + 90 ° to −150 °, it is in the normal mode, and when it is + 30 ° to −30 °, the drive motor 2 is stopped. From + 90 ° to + 30 °, it is the feeding direction, and the maximum output at this time is limited to, for example, 20% or less to reduce the risk of yarn entanglement. The winding direction is from -30 ° to -150 °. At this time, the maximum output is not limited and can be used up to 100%. With such a configuration, switching between the high-speed fall mode and the normal mode and adjustment of the output in the normal mode can be continuously performed by the same operation method.

More specifically, the control unit 18 is adapted to execute, for example, a control step as shown in FIG. That is, first, the control unit 18 determines whether or not there is an input signal from the motor output adjusting unit 22 (whether or not the fisherman operates the motor output adjusting unit 22) (step S1). When the motor output adjusting unit 22 is operated and an input signal is input from the motor output adjusting unit 22 to the control unit 18, the control unit 18 drives a voltage corresponding to the signal input from the motor output adjusting unit 22 to drive the motor 2. (The motor output is determined according to the input) (step S2). At this time, the control unit 18 always receives the mode switching signal from the mode input unit 16 and determines whether or not the high-speed fall mode is set by the mode switching signal (step S3). If this determination is NO, that is, if the high-speed drop mode is not set, the control unit 18 determines that the mode is normal, and subsequently applies a voltage corresponding to the signal input from the motor output adjustment unit 22. Continue to supply to the drive motor 2.

On the other hand, when the determination in step S3 is YES, that is, when the control unit 18 determines that the high-speed drop mode is set by the mode switching signal, the control unit 18 is driven in the reverse rotation of the drive motor 2 for feeding the fishing thread. Based on the detection signal from the tension sensor 20 that is constantly received, it is determined whether or not the current tension T of the fishing thread is below the first threshold value T1 (step S4). When the tension T is lower than the first threshold value T1 (when the determination in step S4 is YES), the voltage is lower than the voltage corresponding to the signal input from the motor output adjusting unit 22 (depending on the tension). For example, a decrease of about 0.1 to 10%) is supplied to the drive motor 2 (step S7), and the release speed of the fishing thread by the drive motor 2 is reduced to match (synchronize with) the falling speed of the device.

On the other hand, when the current tension T of the fishing thread based on the detection signal of the tension sensor 20 does not fall below the first threshold value T1 (when the determination in step S4 is NO), the control unit 18 has the current tension T of the second. Further, it is determined whether or not the threshold value T2 is exceeded (step S5). When the tension T exceeds the second threshold value T2 (when the determination in step S5 is YES), the voltage is higher than the voltage corresponding to the signal input from the motor output adjusting unit 22 (depending on the tension). For example, an increase of about 0.1 to 10%) is supplied to the drive motor 2 (step S6), and the discharge speed of the fishing thread by the drive motor 2 is increased to match (synchronize with) the falling speed of the device.

When the current tension T of the fishing thread based on the detection signal of the tension sensor 20 does not exceed the second threshold value T2 (when the determination in step S5 is NO), the control unit 18 continues to perform the same as in the normal mode. The drive motor 2 is continuously supplied with the voltage corresponding to the signal input from the motor output adjusting unit 22.

As described above, according to the fishing electric reel 1 of the present embodiment, when the high-speed drop mode is set, the tension detected by the tension sensor 20 when the drive motor 2 for feeding the fishing thread is driven in the reverse rotation. When T is below the first threshold value T1 (for example, when the release speed of the fishing thread by the drive motor 2 greatly exceeds the falling speed of the tackle), it is lower than the voltage corresponding to the signal input from the motor output adjusting unit 22. Since the voltage is supplied to the drive motor 2 (that is, to reduce the release speed of the fishing thread by the drive motor 2 to match the falling speed of the gimmick), the so-called backlash phenomenon in which the fishing thread indulges and loosens is prevented. It is possible to avoid situations where the fishing thread is entangled or entangled.

Further, according to the present embodiment, when the high-speed drop mode is set, the tension T detected by the tension sensor 20 is larger than the first threshold value T1 when the drive motor 2 for feeding the fishing thread is driven in the reverse rotation. When the threshold value T2 of 2 is exceeded (for example, when the release speed of the fishing thread by the drive motor 2 is lower than the falling speed of the device), a voltage higher than the voltage corresponding to the signal input from the motor output adjusting unit 22 is applied to the drive motor. Since it is supplied to No. 2 (that is, to increase the release speed of the fishing thread by the drive motor to match the falling speed of the device), it is possible to realize the fishing thread release speed according to the falling speed of the device without hindering the falling of the device. It is possible to promote a high-speed fall of.

That is, according to the present embodiment, it is not necessary for the user (fisherman) to perform troublesome and difficult operations such as synchronizing the release speed of the fishing thread by the drive motor 2 and the gimmick fall speed, and the change in the usage environment (water depth and tide). It is possible to realize a fishing thread feeding operation that corresponds well to the flow, etc., without backlash.

FIG. 4 shows a block diagram of the electric reel 1 for fishing (particularly its control device 15) according to the modified example. As shown in the figure, in this modification, the control unit 18 is based on the detection speed from the speed sensor 24 as the speed detection unit for detecting the rotation speed of the spool 4 and the target speed input from the motor output adjustment unit 22. It is configured as a control unit that determines the voltage to be supplied to the drive motor 2 and controls the operation of the drive motor 2 by PID (the determined voltage is supplied to the drive motor 2 via the amplifier 30). Therefore, when the mode control described in FIGS. 2 and 3 is realized in such a PID control mode, the PID control unit 18 uses a mode switching signal to perform a high-speed drop mode when the drive motor 2 for feeding the fishing thread is driven in reverse rotation. When set to, the target speed is lowered when the tension T detected by the tension sensor 20 is below the first threshold value T1, and the target is when the tension T detected by the tension sensor 20 exceeds the second threshold value T2. Increase speed.

More specifically, the PID control unit 18 executes a control step as shown in FIG. 5, for example. That is, first, as in FIG. 3, the PID control unit 18 determines whether or not there is an input signal from the motor output adjusting unit 22 (step S1), and if there is an input signal, the motor output adjusting unit 22 A voltage corresponding to the signal input from is supplied to the drive motor 2 (step S2). At this time, the PID control unit 18 also determines whether or not the high-speed fall mode is set by the mode switching signal (step S3), and if this determination is NO, that is, if the high-speed fall mode is not set. , The normal mode is determined, and subsequently, the voltage corresponding to the signal input from the motor output adjusting unit 22 is continuously supplied to the drive motor 2.

On the other hand, when the determination in step S3 is YES, that is, when it is determined that the PID control unit 18 is set to the high-speed drop mode by the mode switching signal, the PID control unit 18 drives the reverse rotation of the drive motor 2 for feeding the fishing thread. Occasionally, it is determined whether or not the current tension T of the fishing thread is lower than the first threshold value T1 based on the detection signal from the tension sensor 20 that is constantly received (step S4). Then, when the tension T is lower than the first threshold value T1 (when the determination in step S4 is YES), the target speed is lowered (for example, a decrease of about 0.1 to 10% depending on the tension) (step S9). ), The discharge speed of the fishing thread by the drive motor 2 is lowered to match (synchronize) with the falling speed of the device.

On the other hand, when the current tension T of the fishing thread based on the detection signal of the tension sensor 20 does not fall below the first threshold value T1 (when the determination in step S4 is NO), the PID control unit 18 has the current tension T of the first. It is further determined whether or not the threshold value T2 of 2 is exceeded (step S5). Then, when the tension T exceeds the second threshold value T2 (when the determination in step S5 is YES), the target speed is increased (for example, an increase of about 0.1 to 10% depending on the tension) (step S8). ), The release speed of the fishing thread by the drive motor 2 is increased to match (synchronize) with the falling speed of the device.

When the current tension T of the fishing thread based on the detection signal of the tension sensor 20 does not exceed the second threshold value T2 (when the determination in step S5 is NO), the PID control unit 18 continues as in the normal mode. , The voltage corresponding to the signal input from the motor output adjusting unit 22 continues to be supplied to the drive motor 2.

Although one embodiment of the present invention has been described above with reference to the drawings, the present invention can be implemented in various modifications without departing from the gist thereof, which is limited to the above-described embodiment. For example, in the above-described embodiment, the structural form of the mode input unit, the motor output adjusting unit, and the tension sensor can be arbitrarily set, and the control device 15 may be integrated with or separately from the electric reel for fishing. There may be.
