  The present invention relates to an electric fishing reel that performs forward and reverse rotation of a spool by forward and reverse rotation of a drive motor to wind and / or feed fishing line to and from the spool.

  2. Description of the Related Art Conventionally, an electric fishing reel that winds a fishing line around a spool by using a driving force of a driving motor is known (see, for example, Patent Document 1 and Patent Document 2). Some reels are of a type in which the spool is rotated forward and backward by forward / reverse rotation driving of a drive motor to electrically wind and / or feed the fishing line to / from the spool.

  In this type of fishing reel, the fishing line is wound around the spool by the forward rotation of the driving motor, and when the device is dropped, the driving motor is driven in the reverse direction so that the fishing line is fed out from the spool. It has become.

  By the way, in the fishing electric reel that feeds the fishing line from the spool by the reverse rotation driving of the driving motor in this way, if the feeding speed (release speed) of the fishing line by the driving motor greatly exceeds the falling speed of the device, the fishing line will be lost and loosen. A so-called backlash phenomenon occurs, and the fishing line may be entangled or twisted.

  On the other hand, if the discharge speed of the fishing line by the drive motor falls below the falling speed of the mechanism, the time required for the mechanism to drop becomes longer and the fishing results also drop (the speed of releasing the fishing line from the spool by the drive motor can be increased). Can not).

  Therefore, in order to avoid such an inconvenience, it is necessary to synchronize the fishing line discharge speed and the mechanism dropping speed by the drive motor. However, in the conventional electric fishing reel, the user (fisher), for example, uses a motor. These speeds are synchronized by adjusting the output of the drive motor by the output adjustment unit, and it is difficult to cope with changes in the usage environment (water depth, tide flow, etc.).

  The present invention has been made paying attention to the above-described problem, and can be used for fishing that can increase the discharge speed of the fishing line from the spool by the drive motor (high-speed dropping of the device) without causing a backlash phenomenon. An object is to provide an electric reel.

  In order to achieve the above object, the present invention provides an electric fishing reel that winds and / or feeds a fishing line to and from a spool by rotating the spool forward and backward by forward and reverse rotation of a drive motor. A motor output adjustment unit for adjusting the motor output of the motor, a tension detection unit for detecting the tension of the fishing line, and a voltage corresponding to a signal input from the motor output adjustment 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 a voltage supplied to the drive motor is adjusted based on the tension of a fishing line when the drive motor is driven in reverse rotation; and the tension The operation of the drive motor in response to 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 A control unit for controlling, and when the control unit is set to the normal mode by the mode switching signal, the control unit supplies a voltage corresponding to a signal input from the motor output adjustment unit to the drive motor. When the high speed drop mode is set by the mode switching signal, when the tension detected by the tension detection unit falls below a first threshold during the reverse rotation driving of the drive motor for feeding the fishing line, the motor When a voltage lower than the voltage corresponding to the signal input from the output adjustment unit is supplied to the drive motor, and the tension detected by the tension detection unit exceeds a second threshold value that is greater than the first threshold value A voltage higher than a voltage corresponding to a signal input from the motor output adjusting unit is supplied to the drive motor.

  The present invention also relates to an electric fishing reel that rotates the spool forward and backward by forward and reverse rotation of the drive motor to wind and / or feed the fishing line to and from the spool, and adjusts the motor output of the drive motor. A motor output adjusting unit for detecting the fishing line tension, a tension detecting unit for detecting the tension of the fishing line, a normal mode in which a voltage corresponding to a signal input from the motor output adjusting unit is supplied to the drive 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 line during reverse rotation driving of the motor, and a detection signal from the tension detection unit And a mode switching signal from the input unit and an input signal from the motor output adjusting unit, and detecting the rotation speed of the spool. A control unit that determines the voltage to be supplied to the drive motor based on the detection speed from the speed detection unit and the target speed input from the motor output adjustment unit, and controls the operation of the drive motor; When the control unit is set to the normal mode by the mode switching signal, the control unit supplies a voltage corresponding to the signal input from the motor output adjustment unit to the drive motor, and the mode switching signal causes the high-speed drop. When the mode is set, the target speed is decreased when the tension detected by the tension detection unit falls below the first threshold when the drive motor for feeding the fishing line is driven in reverse rotation, and is detected by the tension detection unit. The target speed is increased when the applied tension exceeds a second threshold value that is greater than the first threshold value.

  According to the above configuration, when the high speed drop mode is set, when the tension detected by the tension detection unit is lower than the first threshold value when the drive motor that feeds the fishing line rotates backward (for example, the fishing line by the drive motor). When the discharge speed of the motor greatly exceeds the falling speed of the device), a voltage lower than the voltage corresponding to the signal input from the motor output adjustment unit is supplied to the drive motor (or the target speed is reduced) (that is, Therefore, the so-called backlash phenomenon in which the fishing line sags and loosens can be prevented, and the situation where the fishing line becomes entangled or twisted can be avoided.

  Further, according to the above configuration, when the high speed drop mode is set, the second threshold value in which the tension detected by the tension detection unit is larger than the first threshold value when the drive motor that feeds the fishing line is driven in reverse rotation is set. When exceeding (for example, when the discharge speed of the fishing line 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 adjustment unit is supplied to the drive motor (or the target (That is, to increase the discharge speed of the fishing line by the drive motor to match the falling speed of the mechanism), and to achieve the fishing line discharge speed according to the falling speed of the mechanism without hindering the falling of the mechanism. Can prompt 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 fishing line discharge speed and the device dropping speed with the drive motor, and changes in the use environment (water depth and tide flow). Etc.) can be realized without backlash.

  According to the present invention, it is possible to obtain an electric fishing reel capable of realizing an increase in the fishing line discharge speed from the spool by the drive motor (high-speed dropping of the mechanism) without causing a backlash phenomenon.

It is a block diagram of the electric reel for fishing of FIG. 1 (especially the control apparatus). It is a flowchart which shows the control action of the control apparatus of FIG. It is a block diagram of the electric reel for fishing (especially the control apparatus) which concerns on a modification. It is a flowchart which shows the control action of the control apparatus of FIG. It is explanatory drawing which illustrates the operation mode of the motor output adjustment part which can switch continuously between high-speed fall mode and normal mode.

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 forward and backward by a drive motor 2 and forward and reverse rotation of the drive motor 2 to change the fishing line (FIGS. 1 and 2). (Not shown) includes a cylindrical spool 4 that winds and / or feeds out, and a reel body 6 that accommodates and holds the spool 4. 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 placed inside the cylindrical spool 4 while being accommodated in, for example, a motor housing. It may be supported and fixed in a non-rotatable manner, and is preferably powered by a power supply P that is detachably mounted on the reel body 6.

  The drive motor 2 and the spool 4 are connected to each other by a power transmission mechanism (power transmission path) 10 so that power can be transmitted. 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. A speed reduction mechanism that decelerates the power of the power and transmits the power to the spool 4 may be provided.

  The fishing electric reel 1 according to the present embodiment is provided with a level wind device 40 for winding a fishing line around the spool 4 in parallel. The level wind device 40 is configured such that when the drive motor 2 is driven to rotate, a guide body 42 through which the fishing line fed from the spool 4 is reciprocated in the left-right direction in conjunction with the drive motor 2. Along with the operation, the fishing line is wound around the spool 4 evenly.

  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 (not shown in FIG. 1) provided on the reel body 6 at a position operable by a finger, a tension sensor 20 as a tension detecting unit for detecting the tension of the fishing line, and a motor The normal mode in which a voltage corresponding to a signal input from the output adjustment unit 22 is supplied to the drive motor 2 and the voltage supplied to the drive motor 2 are adjusted based on the tension of the fishing line when the drive motor 2 is driven in reverse rotation. 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 a motor output. Receiving an input signal from the adjustment unit 22 comprises a controller 15 and a control unit 18 for controlling the operation of the drive motor 2.

  Here, examples of the tension sensor 20 include a sensor using a strain gauge that converts strain of a member that receives tension into a change in electric resistance. In addition, a method using a piezoelectric element that detects pressure by converting the pressure applied to a member subject to tension to a voltage, a method that detects the position of a balance between a linear spring and tension by a position sensor, and exerts tension on a ferromagnetic material. It is conceivable to use a magnetostrictive sensor that detects a change in magnetic permeability due to the magnetostrictive effect generated at the time. 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. In addition to the switch operation, a known input method such as voice input or motion input can be used. Further, the mode input unit 16 may use a method of automatically switching modes when a predetermined condition is detected by a microcomputer and various detection devices, in addition to switching by the user's intention.

  In addition, 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 adjustment unit 22 to the drive motor 2 and also by the mode switching signal. When the high speed drop mode is set, the motor output adjusting unit 22 inputs the tension T detected by the tension sensor 20 below the first threshold T1 when the drive motor 2 for feeding the fishing line is driven in reverse rotation. When the tension T detected by the tension sensor 20 exceeds a second threshold T1 that is larger than the first threshold T1, a motor output adjusting unit is supplied. 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 T1 is preferably in the range of, for example, 5 gf to 100 gf, and the second threshold T2 is preferably in the range of, for example, 1.5 to 10 times T1. If the value of the first threshold T1 is too large, the drop speed cannot be sufficiently increased. In addition, if the value of the first threshold T1 is too small, there is a problem that the risk of thread snarling increases when receiving a disturbance, the required accuracy of the tension sensor is increased, and the cost is increased.

  Further, the control unit 18 may automatically switch to the normal mode when the fishing line is wound. At the time of winding, the risk of yarn entanglement does not increase even if the number of rotations of the drive motor 2 is increased. Therefore, the fastest winding is when the applied voltage to the drive motor 2 is maximized. This is because it is obvious. Therefore, there is little need for the high speed drop mode when winding. On the other hand, at the time of feeding the fishing line, as described above, if the rotational speed of the drive motor 2 is too fast, a thread entanglement occurs, and therefore there is an optimum speed for feeding the fishing line the fastest. Depending on the user's purpose, it is preferable to be able to switch between a high speed drop mode for feeding the fishing line earliest and a normal mode for feeding according to the lever operation.

  Further, the high-speed drop mode and the normal mode may be switched continuously according to the operation of the motor output adjustment unit 22. An example is shown in FIG. The motor output adjustment unit 22 in 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 between + 150 ° and + 90 °, it is in the high speed drop mode, when it is between + 90 ° and −150 °, it is in the normal mode, and when it is between + 30 ° and −30 °, the drive motor 2 is stopped. The feeding direction is from + 90 ° to + 30 °, 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 °, and at this time, the maximum output is not limited and 100% can be used. With such a configuration, switching between the high-speed drop mode and the normal mode and the adjustment of the output in the normal mode can be continuously performed by the same operation method.

  More specifically, the control unit 18 executes a control step as shown in FIG. 3, for example. That is, first, the control unit 18 determines whether there is an input signal from the motor output adjustment unit 22 (whether the angler has operated the motor output adjustment unit 22) (step S1). When the motor output adjustment unit 22 is operated and an input signal is input from the motor output adjustment unit 22 to the control unit 18, the control unit 18 supplies a voltage corresponding to the signal input from the motor output adjustment unit 22 to the drive motor 2. (The motor output is determined according to the input) (step S2). At this time, the control unit 18 always receives a mode switching signal from the mode input unit 16, and determines whether or not the high-speed drop mode is set by the mode switching signal (step S3). When this determination is NO, that is, when the high-speed drop mode is not set, the control unit 18 determines that the normal mode is selected, and subsequently, determines a voltage corresponding to the signal input from the motor output adjustment unit 22. The supply to the drive motor 2 is continued.

  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 performs the reverse rotation driving of the drive motor 2 for feeding the fishing line, 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 line is below the first threshold value T1 (step S4). When the tension T is lower than the first threshold T1 (when the determination at step S4 is YES), a voltage lower than the voltage corresponding to the signal input from the motor output adjustment 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 discharge speed of the fishing line by the drive motor 2 is lowered to match (synchronize) with the dropping speed of the device.

  On the other hand, when the current tension T of the fishing line based on the detection signal of the tension sensor 20 does not fall below the first threshold T1 (when the determination in step S4 is NO), the control unit 18 determines that the current tension T is the second. It is further determined whether or not the threshold value T2 is exceeded (step S5). When the tension T exceeds the second threshold T2 (when the determination in step S5 is YES), a voltage higher than the voltage corresponding to the signal input from the motor output adjustment 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 fishing line discharge speed by the drive motor 2 is increased to match (synchronize with) the falling speed of the device.

  If the current fishing line tension T 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, as in the normal mode. The voltage corresponding to the signal input from the motor output adjustment unit 22 is continuously supplied to the drive motor 2.

  As described above, according to the electric fishing 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 that feeds the fishing line is reversely driven. When T falls below the first threshold T1 (for example, when the fishing line discharge speed by the drive motor 2 greatly exceeds the falling speed of the device), the voltage is lower than the voltage corresponding to the signal input from the motor output adjustment unit 22 Since the voltage is supplied to the drive motor 2 (that is, to reduce the fishing line discharge speed by the driving motor 2 to match the dropping speed of the device), the so-called backlash phenomenon that the fishing line sags and loosens is prevented. The situation where a fishing line gets entangled or drowned can be avoided.

  Further, according to the present embodiment, when the high speed drop mode is set, the tension T detected by the tension sensor 20 is greater than the first threshold T1 when the drive motor 2 for feeding out the fishing line is driven in reverse rotation. When the threshold value T2 of 2 is exceeded (for example, when the discharge speed of the fishing line by the drive motor 2 is lower than the dropping speed of the device), the voltage higher than the voltage corresponding to the signal input from the motor output adjustment unit 22 2 (ie, to increase the discharge speed of the fishing line by the drive motor to match the falling speed of the mechanism), the fishing line discharge speed corresponding to the falling speed of the mechanism can be realized without hindering the falling of the mechanism, Can prompt high-speed fall.

  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 fishing line discharge speed and the device dropping speed by the drive motor 2, and changes in the usage environment (water depth and tide). The fishing line feeding operation that corresponds well to the flow etc.) can be realized without backlash.

  FIG. 4 shows a block diagram of an electric fishing reel 1 (particularly its control device 15) according to a modification. As illustrated, in this modification, the control unit 18 is based on the detection speed from the speed sensor 24 as a speed detection unit that detects the rotation speed of the spool 4 and the target speed input from the motor output adjustment unit 22. Thus, it is configured as a control unit that determines the voltage to be supplied to the drive motor 2 and performs PID control of the operation of the drive motor 2 (the determined voltage is supplied to the drive motor 2 via the amplifier 30). Therefore, in the case of realizing the mode control described above with reference to FIGS. 2 and 3 in such a PID control mode, the PID control unit 18 uses the mode switching signal during the reverse rotation driving of the drive motor 2 for feeding the fishing line, so that the high speed drop mode is set. When the tension T detected by the tension sensor 20 falls below the first threshold T1, the target speed is lowered, and when the tension T detected by the tension sensor 20 exceeds the second threshold T2, Increase speed.

  More specifically, the PID control unit 18 executes control steps 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 adjustment unit 22 (step S1). If there is an input signal, the motor output adjustment unit 22 is present. Is supplied to the drive motor 2 in accordance with the signal input from (step S2). At this time, the PID control unit 18 also determines whether or not the high speed drop mode is set by the mode switching signal (step S3). If this determination is NO, that is, the high speed drop mode is not set. Then, it is determined that the current mode is the normal mode, and subsequently, the voltage corresponding to the signal input from the motor output adjustment unit 22 is continuously supplied to the drive motor 2.

  On the other hand, if the determination in step S3 is YES, that is, if the PID control unit 18 determines that the high speed drop mode is set by the mode switching signal, the PID control unit 18 drives the reverse rotation of the drive motor 2 for feeding the fishing line. Sometimes, based on the detection signal from the tension sensor 20 that is constantly received, it is determined whether or not the current fishing line tension T is below the first threshold T1 (step S4). When the tension T falls below the first threshold T1 (when the determination in step S4 is YES), the target speed is decreased (decrease by about 0.1 to 10%, for example, depending on the tension) (step S9). ) Reduce the fishing line discharge speed by the drive motor 2 to match (synchronize) with the falling speed of the device.

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

  If the current fishing line tension T 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 adjustment unit 22 is continuously 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 is limited to the above-described embodiment, and can be implemented with various modifications without departing from the gist thereof. For example, in the above-described embodiment, the mode input unit, the motor output adjustment unit, and the tension sensor can be arbitrarily configured, and the control device 15 may be integrated with the fishing reel or separately. There may be.
