Description

  The present invention relates to a motor control device and a motor control device for an electric reel that controls a motor that drives a spool around which a fishing line is wound.

  The electric reel rotates the spool in the yarn winding direction with a motor. Conventionally, in an electric reel, the rotational speed of the motor, that is, the spool winding speed can be adjusted to a high or low speed by operating a switch. When the spool winding speed is set, the current is controlled so as to maintain the speed regardless of the load.

  Among these types of electric reels, there are known ones having a ship edge stop mode in which the motor is turned off when the device reaches the ship edge. When having such a boat edge stop mode, when fishing a fish or when exchanging bait, the device is arranged on the boat edge, so that the device and the fish can be easily collected, and the rework is quick.

  2. Description of the Related Art Conventionally, a motor control device for an electric reel having a boat edge stop mode that can wind up to the tip of a fishing rod is known (see, for example, Patent Document 1). In the conventional motor control device, the rotation direction and the rotation speed of the spool are detected, and the yarn length is measured by the detected rotation direction and rotation speed of the spool. When the measured yarn length reaches the ship's edge position, the drive current flowing through the motor is reduced, and the motor is stopped when a predetermined condition is considered that the device has been wound up to the tip.

JP 2004-73089 A

When the length of the fishing line is measured by the rotation direction and the number of rotations of the spool, a deviation may occur between the actual line length and the measured line length due to a load acting on the fishing line. For example, if a large fish is exerted on the fishing line, such as time took load (tension) is large in gimmicks, thus wound with a small winding diameter than the winding diameter as memorize. For this reason, a numerical value larger than the fishing line length that has actually been wound up is displayed.

Also, when the load acting on the fishing line is small, such as when fishing is performed by flowing the fishing hook from the float to the bottom without using a weight at the time of collecting the device or fishing for a hookfish, the diameter is larger than the memorized spool diameter. It will be rolled up. For this reason, a numerical value smaller than the length of the fishing line that is actually unwound is displayed.

  For this reason, in the above-described conventional configuration, there is a risk that the motor control device may determine that the device is not wound up to the ship edge position even though the device is actually wound up to the ship edge position at the time of collecting the device where the load does not act much. There is. Due to such a determination, there is a possibility that the operation of deceleration or stop is delayed, and the device is caught on the guide at the tip. If the device is caught by the guide at the tip, the guide may be damaged or the position of the device may be shifted. Alternatively, when the vehicle is rolled up with a large load, it is necessary to redrive the motor or wind it up by hand until the device is actually at hand after stopping at the ship's edge.

  An object of the present invention is to make it possible to accurately place a device on a ship's edge regardless of a load acting on a fishing line.

An electric reel motor control device according to a first aspect of the invention is a device for controlling a motor that drives a spool around which fishing line is wound, and is a yarn length measuring means, a load detecting means, a stop yarn length setting means, and a motor control means. And rotation detection means . The line length measuring means measures the line length of the fishing line fed from the spool. The load detection means detects a load acting on the fishing line. The stop yarn length setting means sets a stop yarn length for stopping the rotation of the motor at the time of winding according to the detection result of the load detection means. The motor control means stops the rotation of the motor when the yarn length measured by the yarn length measuring means reaches the set stop yarn length. The rotation detection means detects the rotation direction and rotation speed of the spool. Based on the detection result of the rotation detecting means, the stop yarn length setting means is based on the first yarn length as a standard stop yarn length that is set in advance after a predetermined time has elapsed since the motor started rotating at the time of winding. The average value of the load detected by the load detecting means while being wound up to the long second yarn length is compared with a predetermined value. When the average value is smaller than the predetermined value, the first yarn length is longer than the first yarn length and shorter than the second yarn length. Set the stop yarn length to 3 yarn lengths.

  In this motor control device, when the spool is rotated by the motor in the line winding direction and the fishing line is wound up, the load acting on the fishing line at that time is detected by the load detection means based on the value of the current flowing through the motor, for example. The Then, in the stop yarn length setting means, depending on the magnitude of the load, for example, when the load is small, the measurement value of the yarn length measurement means is shorter than the actual yarn length, so the device is arranged on the ship edge as compared to when the load is large. Increase the set value of the stop yarn length for Then, when winding the fishing line, if the measured line length becomes the stop line length, the rotation of the motor is stopped and the winding of the fishing line is stopped. Here, since the stop yarn length can be set according to the load acting on the fishing line, the stop yarn length can be set appropriately according to the magnitude of the load. For this reason, regardless of the load acting on the fishing line, the device can be accurately arranged on the ship's edge.

Further, when the load is smaller than the predetermined value, the stop line length is set longer than when the load is larger than the predetermined value, so that the device can be arranged on the ship edge with higher accuracy regardless of the load acting on the fishing line. Further, it is possible to prevent the device from being caught by the guide at the tip.

Furthermore, since the stop yarn length is set by comparing the average value of the fluctuating load with a predetermined value, the device can be arranged on the ship edge with higher accuracy. In particular, when the first yarn length is set to the standard stop yarn length, the ship edge stop position becomes longer than the standard stop yarn length when the load is small, so that the device can be easily arranged on the ship edge. Further, it is possible to prevent the device from being caught by the guide at the tip.

The motor control device of the electric reel according to the invention 2, in the device according to the invention 1, when the average value exceeds a predetermined value, sets the stop yarn length to the first yarn length following yarn length previously set. In this case, if the load exceeds the specified value and the catch is caught, the deviation between the measured yarn length and the actual yarn length is small, so the previously set stop yarn length is used. This makes it easier to place the device at the optimal position according to the ship.

An electric reel motor control device according to a third aspect of the invention is the device according to the first or second aspect , wherein the stop yarn length setting means sets the stop yarn length to the first yarn length when the motor control means is powered on. To do. In this case, when starting fishing, the device can be arranged at a standard ship edge stop position.

The motor control device for an electric reel according to a fourth aspect of the present invention is the device according to any one of the first to third aspects, wherein the stop yarn length setting means has a measurement result of the yarn length measuring means equal to or less than the first yarn length and a rotation detecting means. When it is determined that the rotation of the spool has stopped for a predetermined time or more, the yarn length at that time is set as the stop yarn length. In this case, since the edge stop position that changes depending on the size of the ship can be set to the position where the angler actually stopped, the optimum edge stop position can always be set.

The motor control device for an electric reel according to a fifth aspect is the device according to the third or fourth aspect , wherein the stop line length setting means is configured to feed the fishing line after the motor stops rotating at the third line length and wind it up by the motor. When the average value exceeds a predetermined value, the next stop yarn length is set to the first yarn length. In this case, when the average value of the load exceeds a predetermined value in the winding after setting the third yarn length with a long stop yarn length, such as when a fish is caught on the mechanism, the first yarn length shorter than the third yarn length is set. Since the stop yarn length is set as the yarn length, the device is arranged on the ship's edge, making it easier to take in the fish that has been applied to the device.

The motor control device for an electric reel according to a sixth aspect of the present invention is the device according to any one of the first to fifth aspects, wherein a speed reduction yarn length for decelerating the rotation of the motor is detected based on the detection results of the load detection means and the rotation detection means during winding. A deceleration yarn length setting means for setting is further provided, and the motor control means decelerates the rotation of the motor by the deceleration yarn length. In this case, the motor rotation deceleration start position is set in consideration of not only the winding speed but also the load. For example, in the case of low-load high-speed winding, it is advanced so as not to jump out of the water surface of the device. In the case of high load and low speed hoisting, it is easier to stop at the set ship's edge stop position with precision, and the load acting on the motor and the motor Regardless of the number of revolutions, the device can be arranged at a predetermined position such as a ship edge at the time of winding.

  According to the present invention, since the stop yarn length can be set according to the load acting on the fishing line, the stop yarn length can be set appropriately according to the load. For this reason, regardless of the load acting on the fishing line, the device can be arranged on the ship's edge.

As shown in FIG. 1, an electric reel according to an embodiment of the present invention includes a reel body 1 mounted on a fishing rod R, a spool rotating handle 2 disposed on the side of the reel body 1, and a handle 2. It mainly includes a star drag 3 for drag adjustment arranged on the reel body 1 side.

  The reel body 1 includes a frame 7 including a pair of left and right side plates 7 a and 7 b and a plurality of connecting members 8 that connect the left and right side plates 7 a and 7 b, and left and right side covers 9 a and 9 b that cover the left and right sides of the frame 7. A rotation shaft of the handle 2 is rotatably supported by the side cover 9b on the handle 2 side (right side in FIG. 1), and the side cover 9a on the side opposite to the handle 2 (left side in FIG. 1) has an external battery or the like. A connector 19 for connecting a power cord 18 for connecting the power PS is provided.

  A spool 10 connected to the handle 2 is rotatably supported inside the reel body 1. Inside the spool 10, a direct-current drive motor 12 that rotates the spool 10 in the yarn winding direction is disposed. Further, a clutch operation lever 11 and a change lever 13 are disposed on the side surface of the reel body 1 on the handle 2 side. The clutch operation lever 11 is provided to perform a clutch operation for turning on / off the drive transmission between the handle 2 and the motor 12 and the spool 10. When this clutch is turned on, the yarn unwinding operation can be stopped during the unwinding of the yarn due to its own weight. The change lever 13 is a lever member for turning on and off the rotation of the motor 12 and designating the rotation of the motor 12 from the stop state to the maximum rotation state by the swing position. The change lever 13 can adjust, for example, the motor 12 from a stop state to a rotation state in 30 stages, for example. The change lever 13 has a rotary encoder, for example, and can determine the rotation stage based on the swing angle.

  A counter case 4 is fixed to the top of the reel body 1. The counter case 4 is disposed on the upper portion of the reel body 1 and has a display window 20 formed on the upper surface. On the upper surface of the counter case 4, as shown in FIG. 2, a display unit 5 comprising a liquid crystal display for displaying the water depth and the shelf position of the device through the display window 20 on the basis of two criteria, from the water surface and from the bottom. The switch operation unit 6 is provided around the display unit 5. Inside the counter case 4, a reel control unit 30 that controls the motor 12 and the display unit 5 is provided.

  The display unit 5 is disposed at the lower left of the water depth display area 5a, a three-digit memo water depth display area 5b disposed at the lower right of the four-digit seven-segment water depth display area 5a disposed at the center. And a stage number display area 5c. The step number display area 5c displays the position (number of steps) of the change lever 13 in, for example, 30 steps.

  The switch operation unit 6 includes a menu switch MN arranged side by side on the lower side in FIG. 2 of the display unit 5, a 0-set determination switch ZD, and a memo switch MM arranged on the right side. Each time the menu switch MN is pressed, the bottom / thread feed display blinks in order. Pressing the 0 set determination switch ZD can turn on and off the blinking display part. The zero set determination switch ZD turns on and off the mode selected by the operation of the menu switch MN. Further, when the button is pressed for a long time (for example, 3 seconds or longer), the device can be set to 0 for setting the water depth of the device 5 on the display unit 5 to 0. When performing 0 set processing, the angler matches the device to the surface of the water. The memo switch MM is used when storing the depth of water on the shelf where the fish are swarmed or the seabed in the display data storage area 50 described later.

  The reel control unit 30 includes a microcomputer including a CPU, a RAM, a ROM, an I / O interface and the like disposed in the counter case 4. The reel control unit 30 executes various control operations such as display control of the display unit 5 and motor drive control according to the control program. As shown in FIG. 3, the reel control unit 30 includes a change lever 13, various switches of the switch operation unit 6, a spool sensor (an example of a rotation detection unit) 41, a spool counter 42, and a current value detection unit. (An example of load detecting means) 43 is connected. Further, the buzzer 44, the PWM drive circuit 45, the display unit 5, the storage unit 46, and other input / output units are connected to the reel control unit 30.

  The spool sensor 41 is composed of two reed switches arranged side by side in front and rear, and can detect the rotation direction of the spool 10 depending on which reed switch has issued a detection pulse first. Further, the number of rotations of the spool can be detected by the detection pulse. The spool counter 42 is a counter that counts the detection pulses of the spool sensor 41, and rotational position data relating to the rotational speed of the spool 10 is obtained from the counted value. The spool counter 42 decreases when the spool 10 rotates in the forward direction (rotation in the yarn feeding direction) and increases when the spool 10 rotates in the reverse direction. The yarn length can be measured from this count value. The current value detection unit 43 detects a load (tension) acting on the fishing line by detecting a current flowing through the motor 12. The buzzer 44 is used to sound an alarm sound. The PWM drive circuit 45 drives the motor 12 by PWM, and the duty ratio is controlled by the reel control unit 30 to drive the motor 12 according to the speed and the tension acting on the fishing line.

  The storage unit 46 is composed of a nonvolatile memory such as an EEPROM, for example. As shown in FIG. 4, the storage unit 46 stores a display data storage area 50 for storing display data such as shelf positions, and a yarn length data for storing yarn length data indicating the relationship between the actual yarn length and the spool rotation speed. A data storage area 51, a rotation data storage area 52 for storing the winding speed (rpm) of the spool 10 according to the number of stages SC and the upper limit value of the winding torque, and a data storage area 53 for storing various data are provided. Yes.

  The rotation data storage area 52 stores data on the maximum duty ratio and the minimum duty ratio for each number of stages in the constant speed mode, and the maximum current value and the minimum current value in the constant tension mode. In this embodiment, for example, when the number of stages SC is from 1 to 4 stages, in this embodiment, the speed of the spool 10 is controlled to a constant speed mode that gradually increases, and from 5 to 30 stages, it acts on the fishing line. Control is performed in a constant tension mode in which the tension gradually increases.

  The data storage area 53 stores various data related to the yarn length. For example, the first yarn length L1 (for example, 6 m), the second yarn length L2 (for example, 21 m), the third yarn length L3 (for example, 10 m), the set ship edge stop position FN and the deceleration position RX before the ship edge stop. The speed coefficient data VA and the load coefficient data TB for setting are also stored.

  Next, specific control processing performed by the reel control unit 30 will be described with reference to the control flowchart of FIG.

  When the electric reel is connected to the external power source PS via the power cord 18, initial setting is performed in step S1 of FIG. In this initial setting, the count value of the spool counter 42 is reset, and various variables and flags are reset. Further, the ship edge stop position FN (an example of the stop water depth) is set to a first yarn length L1 (for example, 6 m) which is a standard ship edge stop position.

  Next, in step S2, display processing is performed. In the display process, various display processes such as water depth display are performed. Here, the stage number SC is displayed in the stage number display area 5c.

  In step S3, it is determined whether or not the water depth LX calculated in each operation mode described later is equal to or less than the first yarn length L1. In step S4, it is determined whether or not any switch of the switch operation unit 6 has been pressed. In step S5, it is determined whether or not the spool 10 is rotating. This determination is made based on the output of the spool sensor 41. In step S6, it is determined whether any other command or input has been made.

  When the water depth LX is equal to or less than the first yarn length L1, the process proceeds from step S3 to step S7. In step S7, it is determined whether or not the water has been stopped for 5 seconds or more at the water depth. The reason for stopping for more than 5 seconds at a water depth of 6 m or less is often when the fish caught on the ship's edge is taken in or the bait is reattached to the device. For this reason, if it is determined that the vehicle has stopped for 5 seconds or more, the process proceeds to step S8, and the water depth LX at that time is set to the ship edge stop position FN. When it is less than 5 seconds, the process proceeds from step S7 to step S4.

  If a switch input is made, the process proceeds from step S4 to step S9 to execute switch input processing. If rotation of the spool 10 is detected, the process proceeds from step S5 to step S10. In step S10, each operation mode process is executed. If any other command or input is made, the process proceeds from step S6 to step S11 to execute other processes.

  In the switch input process of step S9, it is determined whether or not the change lever 13 has been operated in step S15 of FIG. In step S16, it is determined whether or not the memo switch MM has been pressed. In step S17, it is determined whether other switches have been operated. The operation of other switches includes operations of the menu switch MN, the 0 set determination switch ZD, and the like.

If it is determined that the change lever 13 has been swung, the process proceeds from step S15 to step S18. In step S18, it is determined whether or not the change lever 13 has been operated to the stage number SC = 0. In step S19, it is determined whether or not the change lever 13 has been operated to any of the number of stages SC = 1 to 4. In step S20, it is determined whether or not the change lever 13 has been operated to any of the number of stages SC = 5 to 30.

  When the change lever 13 is operated to SC = 0, the process proceeds from step S18 to step S21, and the motor 12 is stopped. When the change lever 13 is operated to any of SC = 1-4, the process proceeds from step S19 to step S22. In step S22, the motor 12 is controlled at a constant speed so that the speed is set for each stage with a duty ratio corresponding to the stage SC. When the change lever 13 is operated to any of SC = 5-30, the process proceeds from step S20 to step S23. In step S23, the tension of the motor 12 is controlled to be constant so that the tension is set for each stage with a current value corresponding to the stage SC.

  When the memo switch MM is operated, the process proceeds from step S16 to step S24. In step S24, the water depth when the memo switch MM is pressed is stored in the display data storage area 50 as a shelf position or a bottom position.

  When another switch input is made, the process proceeds from step S17 to step S25. For example, another switch input corresponding to the operated switch input such as changing from the bottom to the mode or rotating the motor 12 at the maximum rotational speed is performed. Process.

  In each operation mode process in step S10, it is determined in step S31 in FIG. 7 whether or not the rotation direction of the spool 10 is the yarn feeding direction. This determination is made based on which reed switch of the spool sensor 41 has issued a pulse first. If it is determined that the rotation direction of the spool 10 is the yarn feeding direction, the process proceeds from step S31 to step S32. In step S32, every time the spool rotational speed decreases, the data stored in the storage unit 46 is read from the spool rotational speed to calculate the water depth (released yarn length) LX. This water depth LX is displayed in the display process of step S2. In step S33, it is determined whether the obtained water depth LX matches the shelf or bottom position, that is, whether the device has reached the shelf or the bottom. The shelf or bottom position is set in the display data storage area 50 of the storage unit 46 by pressing the memo switch MM when the device reaches the shelf or the bottom. In step S34, it is determined whether or not another mode such as a learning mode.

  When the water depth matches the shelf position or the bottom position, the process proceeds from step S33 to step S35, and the buzzer 44 is sounded to notify that the device has reached the shelf or the bottom. In the case of another mode, the process proceeds from step S34 to step S36, and the designated other mode is executed. If it is not in another mode, each operation mode process is terminated and the process returns to the main routine.

  When the rotation of the spool 10 is determined to be the yarn winding direction, the process proceeds from step S31 to step S37. In step S37, the data stored in the storage unit 46 is read from the spool rotational speed to calculate the water depth LX. This water depth LX is displayed in the display process of step S2.

  In step S38, the setting process of the ship edge stop position FN is performed. In the ship edge position setting process in step S38, it is determined in step S51 in FIG. 8 whether or not the timer TM has started. This timer TM is a timer for measuring the time from the start of winding to the start of load measurement. In this embodiment, the time from the start of winding is set to 2 seconds. Here, the reason why the load is detected 2 seconds after the start of winding is that immediately after winding, the value of the current flowing through the motor 12 becomes large due to acceleration of the motor 12 and the like and is not stable.

  In step S52, it is determined whether or not the timer TM has already expired, that is, whether or not 2 seconds or more have elapsed since the start of winding. In step S53, it is determined whether or not the fishing line has been wound up to a second thread length L2 (for example, 21 m) where the water depth LX is 15 meters before the first thread length L1. This determination is used to determine whether or not to end the load measurement. When step S53 ends, the process returns to each operation mode process.

  If the timer TM has not been started, the process proceeds from step S51 to step S54, the timer TM is started, and the process proceeds to step S52. In step S55, variable N and variable SS are reset to zero. The variable N is a variable for counting the number of load measurements, and the variable SS is a variable for calculating the total load.

  If it is determined that the timer TM has timed up, the process proceeds from step S52 to step S56. In step S56, the variable N is incremented by one. In step S57, the current value from the current value detection unit 43 is read and taken as a load. Note that the reading timing of the current value is performed, for example, every second. In step S58, the acquired tension TN is added to the variable SS, a new variable SS is calculated, and the process proceeds to step S53.

  When the fishing line is wound up to the second line length L2, the process proceeds from step S53 to step S59. In step S59, an average value ST (ST = SS / N) of the load is calculated from the variable SS indicating the total detected load. In step S60, it is determined whether or not the calculated average value ST of the load exceeds a predetermined load Ts (for example, 5A) set in advance.

If it is determined that the average value ST of the load is smaller than the predetermined load Ts, the process proceeds from step S60 to step S61. In step S61, a flag FF indicating that the average load value ST is smaller than the predetermined load Ts is set. In step S62, the boat edge stop position FN is set to a value larger than the third yarn length L3 (for example, 10 m), that is, the first yarn length L1 (for example, 6 m) which is a standard ship edge stop position. That is, when the load acting on the fishing line is small, the ship edge stop position FN is made larger than when the load is large. When step S62 ends, the process returns to each operation mode process. When it is determined that the average value ST of the load exceeds the predetermined load Ts, the process proceeds from step S60 to step S63. In step S63, it is determined whether the flag FF is set. This determination is that, if the flag FF is set, the load was small when it was wound up before this. In this case, since the boat edge stop position FN is set to 10 m, which is the third yarn length L3, when the fish is hooked, the hook is arranged below the boat edge and it is difficult to take in the fish. When the flag FF is set, the process proceeds from step S63 to step S64, and the flag FF is reset. In step S65, the ship edge stop position FN is set to the first yarn length L1 (for example, 6 m), and the process returns to each operation mode process. If the flag FF is not set, the process returns to each operation mode process.

  In step S39 of each operation mode process of FIG. 7, it is determined whether or not the water depth LX has come 10 m before the ship edge stop position FN, that is, whether the device has been rolled up to a position that reaches the ship edge stop position FN 10 m later. This determination is used to set the deceleration position RX. That is, since it is useless to set the deceleration position RX every time the vehicle is wound up, it is determined that if the vehicle is wound up to this position, it is really rolled up to the ship's edge.

  In step S40, it is determined whether or not the water depth LX based on the calculation result matches the deceleration position RX. In step S41, it is determined whether or not the water depth LX based on the calculation result coincides with the ship edge stop position FN.

  When the water depth LX coincides with the water depth of 10 m from the ship edge stop position FN, the process proceeds from step S39 to step S42. In step S42, it is determined whether or not the deceleration position RX has already been set. If it is determined in step S42 that the deceleration position RX has already been set, the process proceeds to step S40. If it is determined that the deceleration position RX is not set, the process proceeds to step S43, the deceleration position RX is set, and the process proceeds to step S40.

  The deceleration position RX is determined by the spool rotation speed data DV based on the detection result of the spool sensor 41 and the load (tension TN) based on the detection result of the current value detection unit 43. Even if the deceleration is set to the same value, the actual deceleration decreases as the load decreases. For this reason, the deceleration position RX as the yarn length data (water depth) for starting deceleration from the ship edge stop position FN is determined by the rotational speed and the load. Specifically, the deceleration position RX is determined by the following formula.

RX = FN + 2 × (VA × DV−TB × TN)
Here, VA is speed coefficient data, and TB is load coefficient data. Note that the speed coefficient data VA and the load coefficient data TB are set so that the value of (VA × DV−TB × TN) changes, for example, between 0.5 and 1.5.

  Therefore, the deceleration position RX becomes, for example, a deceleration position away from the ship edge stop position FN by, for example, a maximum of 3 m when the speed increases and the torque decreases, for example, 2 m before the ship edge stop position FN. When it becomes larger, it becomes a deceleration position approaching the ship edge stop position FN to a minimum of 1 m, for example. To prevent overrun, when the torque is small and the speed is high, the deceleration position RX is greatly changed to a deeper depth than the reference position. When the torque is large and the speed is slow, the deceleration position RX is greatly changed to a shallower depth than the reference position. Let By setting the deceleration position RX according to the speed and torque in this way, the deceleration position RX is far away from the ship edge stop position FN even at the time of low load and high speed such as when collecting a mechanism during constant tension control. A device is easily placed at the ship edge stop position FN. When it has not wound up to the water depth of 10 m from the ship edge stop position FN, it transfers to step S40 from step S39.

  When the water depth LX reaches the deceleration position RX, that is, when the device is wound up to the deceleration position RX, the process proceeds from step S40 to step S44. In step S44, the deceleration position RX is reset. As a result, a new deceleration position RX is set at the next winding. In step S45, the rotation of the motor 12 is decelerated at a predetermined deceleration, and the process proceeds to step S41. When not winding up to the deceleration position RX, the process proceeds from step S40 to step S41.

  When the ship edge stop position FN is reached, the routine proceeds from step S41 to step S46. In step S46, the buzzer 44 is sounded to notify that the device is on the shore. In step S47, the motor 12 is turned off. As a result, when the fish or the fish is caught or when the device is collected and the bait is exchanged, the fish or the device is arranged at a position where it can be easily taken. When it has not wound up to the ship edge stop position FN, it returns to the main routine.

<Features>
(A) Since the ship edge stop position (stop line length) FN can be set according to the load acting on the fishing line, the ship edge stop position FN can be set appropriately according to the magnitude of the load. For this reason, regardless of the load acting on the fishing line, the device can be accurately arranged on the ship's edge.

  (B) When the load is smaller than the predetermined value, the boat edge stop position FN is set longer than when the load is larger than the predetermined value. Therefore, regardless of the load acting on the fishing line, the device is not caught on the tip of the vessel and the device is accurately set on the vessel edge. Can be placed.

  (C) Since the ship edge stop position FN is set by comparing the average value ST of the fluctuating load with the predetermined value Ts, the apparatus can be accurately arranged on the ship edge without being caught by the tip of the ship. . In particular, when the first yarn length L1 is set to the standard ship edge stop position FN, when the load is small, the ship edge stop position FN becomes longer than the standard one, so that the device can be easily placed on the ship edge. Further, it is possible to prevent the device from being caught by the guide at the tip.

  (D) When the average value ST of the load exceeds the predetermined value Ts, the ship edge stop position FN is set to a yarn length equal to or shorter than the first yarn length L1 set previously. For this reason, when the load average value ST exceeds the predetermined value Ts and the catch is caught, the deviation between the measured yarn length and the actual yarn length is small. Using FN, it is easy to place the device at the optimal position according to the ship.

  (E) When the reel controller 30 is turned on, the boat edge stop position FN is set to 6 m which is the first thread length L1, so that the standard ship edge stop position FN is set when fishing is started. Can be arranged.

(F) When it is determined that the yarn length is 6 m (first yarn length) or less and the rotation of the spool 10 is stopped for a predetermined time (for example, 5 seconds), the yarn length at that time is set to the ship edge stop position FN. doing. For this reason, the boat edge stop position FN, which changes depending on the size of the ship, can be set to the position where the angler actually stopped, so that the optimum ship edge stop position can always be set.

  (G) In the winding after the boat edge stop position FN is set to the long third yarn length L3, when the average value of the load exceeds a predetermined value such as when a fish is caught on the device, the second yarn length L3 shorter than the third yarn length L3 Since the ship edge stop position FN is set to one thread length L1, the device is arranged on the ship edge, and it becomes easy to take in fish caught in the device.

  (H) When winding up the device to the ship's edge, the motor 12 is decelerated by shifting the deceleration position in consideration of the load acting on the fishing line and the speed of the motor 12 (rotational speed of the spool 10). For this reason, even if the load or speed fluctuates, the device can be reliably arranged on the ship's edge.

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

  (A) In the above-described embodiment, the ship edge stop position FN is changed by comparing the average value ST of the load acting on the fishing line and the set load Ts, but the present invention is not limited to this. For example, the ship edge stop position may be changed by comparing a load at a certain yarn length with a set load.

  (B) In the embodiment, the load detection start is set 2 seconds after the start of winding, but the present invention is not limited to this. Further, the first yarn length L1 is set to 6 m, the second yarn length L2 for ending the measurement is set to 21 m 15 m before the first yarn length L1, and the third yarn length L3 is set to 10 m. The present invention is not limited by these numerical values. For example, if the maximum value of the fed yarn length is 50 m or less, the third yarn length L3 is set to 8 m, and if it is 200 m or more, the third yarn length L3 is set to 15 m. The value of the three yarn length L3 may be changed. Alternatively, the third yarn length L3 may be obtained by calculation from the detected load and the fed yarn length. In any case, the relationship among the first yarn length L1, the second yarn length L2, and the third yarn length L3 is preferably L2> L3> L1.

  (C) In the above embodiment, the deceleration position is set 10 m before the ship edge stop position, but any position may be used as long as the deceleration position is being set up. Moreover, although the reference of the deceleration position is set to 2 m, this is an example and the reference position is not limited to 2 m.

  (D) In the above embodiment, the load acting on the fishing line is determined based on the value of the current flowing through the motor 12, but the present invention is not limited to this. For example, the torque acting on the motor 12 may be detected by a torque sensor and used as a load acting on the fishing line. Alternatively, the tension acting on the fishing line may be directly detected and used as a load acting on the fishing line.

  (E) In the above embodiment, the case where the load is smaller than the predetermined value has been described. Conversely, when the load is larger than the predetermined value, the fourth yarn length is shorter than the first yarn length L1 (for example, 4 m). The winding may be stopped. Also in this case, the water depth LX that has been stopped for 5 seconds or more at a water depth of 6 m or less is set as a new ship edge stop position FN, and if the load at the next winding is below a predetermined value, the water is stopped at the first yarn length L1. It is desirable.

  (F) The flowcharts of FIG. 5 to FIG. 8 of the embodiment show an example of the processing procedure of the motor control device, and the present invention is not limited to these processing procedures.
