Description

  The present invention relates to a control device, and more particularly to a control device for an electric reel that has a drag mechanism and displays tension acting on a fishing line wound around a spool of an electric reel that can be driven by a motor.

  An electric reel having a function of displaying a tension acting on a fishing line is conventionally known (see, for example, Patent Document 1). In the conventional electric reel, when a new fishing line is wound around the spool, the tension is displayed so that the angler can wind the fishing line around the fishing line with a constant tension. The tension is detected based on the detected current value by detecting the current value flowing through the motor.

  Further, an electric reel that controls the winding speed of a spool in a plurality of stages when fishing is conventionally known (see, for example, Patent Document 2). In the conventional electric reel, the motor is controlled by the duty ratio, and the spool speed is controlled in a plurality of stages.

Japanese Patent No. 2885356 Japanese Patent No. 4427126

  In the electric reel capable of controlling the speed of Patent Document 2 in a plurality of stages, it is conceivable to display the tension actually acting on the fishing line by applying the tension display function described in Patent Document 1. However, in the tension display function of Patent Document 1, the tension is displayed by the current value output from the motor. For this reason, when the drag mechanism is operated and the motor rotates in the winding direction, the display of tension is increased according to the current value. However, in reality, since the drag is slipping, the tension is not increased. That is, the tension display becomes larger than the actual value.

  An object of the present invention is to suppress a change in display of tension even when a drag mechanism is operated in an electric reel control device.

  An electric reel control device according to a first aspect of the present invention is an electric reel control device that has a drag mechanism and displays tension acting on a fishing line wound around a spool of an electric reel that can be driven by a motor. The electric reel control device includes a display, a current value detection means, a tension detection means, a drag operation detection means, a tension correction means, a tension display means, and a motor control means. The current value detection means detects a current value flowing through the motor. The tension detection means detects the tension based on the current value detected by the current value detection means. The drag operation detecting means detects whether the drag mechanism is operated and the spool is sliding with respect to the motor. The tension correction unit corrects the detection result of the tension detection unit when the drag operation detection unit determines that the drag mechanism is operated. The tension display means displays information according to the detected tension, and when the detection result is corrected by the tension correction means, displays information according to the corrected tension on the display. Control the motor in multiple stages.

  In this electric reel control device, when fishing, when the drag mechanism is actuated and it is detected that the spool has slipped with respect to the motor, the tension correcting means corrects the tension detected by the tension detecting means. . When the tension is corrected, the corrected tension is displayed on the display instead of the detected tension. Here, when the drag mechanism is activated and the spool slips, the tension is corrected, so that the fluctuation of the tension display can be suppressed even if the drag mechanism is activated.

  An electric reel control apparatus according to a second aspect of the present invention is the apparatus according to the first aspect, wherein the tension detecting means includes torque detecting means, pincushion diameter acquiring means, and tension calculating means. The torque detecting means detects torque acting on the spool based on the current value detected by the current value detecting means. The bobbin diameter acquisition means acquires the bobbin diameter of the fishing line wound around the spool. The tension calculating means calculates the tension by correcting the torque detected by the torque detecting means with the acquired bobbin diameter.

  In this case, since the torque detected by the value of the current flowing through the motor is corrected by the bobbin diameter and the tension is calculated, the accuracy of the displayed tension is improved even if the bobbin diameter changes.

  The electric reel control device according to a third aspect of the present invention is the electric reel motor control device according to the first or second aspect, wherein the drag operation detecting means is configured such that when the current value detected by the current value detecting means rises above a predetermined value per time, It is determined that the drag mechanism has been activated.

  In this case, when the current value detected by the current value detecting means rises by a predetermined value or more per time, it is determined that the drag mechanism has been operated. Therefore, the operation of the drag mechanism can be detected with high accuracy, particularly when the speed of the spool is controlled.

And further comprising. The motor control means includes first motor control means for controlling the motor so that the rotation speed set by the speed setting means is obtained by referring to the rotation speed detected by the speed detection means. In this case, the rotation speed of the spool can be controlled in a plurality of stages.

  An electric reel control device according to a fifth aspect of the present invention is the device according to the fourth aspect, wherein the first motor control means controls the motor by pulse width modulation control using a duty ratio, and the drag operation detecting means is the first motor. When the duty ratio output by the control means increases by a predetermined value or more per time, it is determined that the drag mechanism is activated.

  In this case, when the spool speed is controlled, the deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  An electric reel control device according to a sixth aspect of the present invention is the device according to the fourth or fifth aspect, further comprising tension setting means capable of setting the tension acting on the fishing line in a plurality of stages. The motor control means has second motor control means for controlling the motor so as to be the tension set by the tension setting means with reference to the tension detected by the tension detection means. In this case, the tension acting on the fishing line can be controlled in a plurality of stages.

  The control device for an electric reel according to a seventh aspect of the present invention is the device according to the sixth aspect, wherein the second motor control means controls the motor by pulse width modulation control using a duty ratio, and the drag operation detecting means is the second motor. When the duty ratio output by the control means increases by a predetermined value or more per time, it is determined that the drag mechanism is activated.

  In this case, when the spool tension is controlled, a deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  An electric reel control device according to an eighth aspect of the present invention is the device according to the sixth or seventh aspect, further comprising control switching means capable of switching between speed control by the first motor control means and tension control by the second motor control means. In this case, constant speed control and constant tension control can be selected according to the type of fishing.

  According to the present invention, when the drag mechanism is activated and the spool slips, the tension is corrected. Therefore, even if the drag mechanism is operated, fluctuations in the display of the tension can be suppressed.

The spool 10 is attached to the spool shaft 14 so as to be integrally rotatable. The spool 10 includes a tubular bobbin trunk 10a, and a large-diameter first flange 10b and a second flange 10c that are integrally formed on both sides of the bobbin trunk 10a. The spool 10 is of a deep groove type in which the diameter of the bobbin trunk 10a is considerably smaller than the diameters of the first flange 10b and the second flange 10c (for example, less than half the diameter). The spool shaft 14 is fixed to the inner peripheral portion of the bobbin trunk 10a by appropriate fixing means such as press fitting.

  The first end of the spool shaft 14 is supported by the first bearing 18a by the spool support portion 17 as described above. The second end (the right end in FIG. 3) of the spool shaft 14 is supported by the second bearing 18b on the second boss portion 8d of the second side cover 8b.

The pinion gear 32 moves along the direction of the spool shaft 14 between the clutch-on position shown in FIG. 3 and the clutch-off position on the right side of FIG. 3 from the clutch-on position. At the clutch-on position, the clutch pin 16a engages with the clutch recess 16b, and the rotation of the pinion gear 32 is transmitted to the spool shaft 14, and the clutch mechanism 16 enters the clutch-on state. In this clutch-on state, the pinion gear 32 and the spool shaft 14 can rotate together. In the clutch-off position, the clutch recess 16b is separated from the clutch pin 16a, and the rotation of the pinion gear 32 is not transmitted to the spool shaft 14. For this reason, the clutch mechanism 16 is in a clutch-off state, and the spool 10 can freely rotate.

The first gear member 82 also meshes with the driven gear 55 of the level wind mechanism 22. The second gear member 83 is disposed between the mechanism mounting plate 19 and the outer surface of the second side plate 7b. The second gear member 83 is an intermediate gear for transmitting the rotation of the first gear member 82 to the pinion gear 32 with its rotational direction aligned. The second gear member 83 is rotatably supported by the mechanism mounting plate 19. The pinion gear 32 is mounted on the second side plate 7b so as to be rotatable around the spool shaft 14 and movable in the axial direction. The pinion gear 32 is controlled by the clutch control mechanism 20 and moves in the axial direction between the clutch-on position and the clutch-off position.

Further, a ratchet wheel 35 of the first one-way clutch 34 is attached to the handle shaft 30 so as to be integrally rotatable. The ratchet wheel 35 is mounted in a state where movement in the axially inward direction (left side in FIG. 4) is restricted. The ratchet wheel 35 is prohibited from rotating in the yarn feeding direction by a ratchet claw (not shown). The base end of the handle shaft 30 is rotatably supported by a bearing (not shown) on the second side plate 7b. The handle shaft 30 is supported by the first boss 8c of the second side cover 8b by a roller-type second one-way clutch 36. The handle shaft 30 is prohibited from rotating in the yarn feeding direction by the first one-way clutch 34. The drag mechanism 29 can be operated by prohibiting the rotation of the handle shaft 30 in the yarn feeding direction. The second one-way clutch 36 quickly prohibits the rotation of the handle shaft 30 in the yarn unwinding direction.

  The drive gear 31 is rotatably mounted on the handle shaft 30. The drive gear 31 is pressed by the drag washer 37. The drive gear 31 is braked for rotation in the yarn feeding direction by the drag mechanism 29. As a result, the rotation of the spool 10 in the yarn unwinding direction is braked.

  The third gear member 84 is provided to transmit the rotation of the handle 2 to the spool 10. The third gear member 84 is coupled to the carrier of the second planetary reduction mechanism 28 so as to be integrally rotatable. The third gear member 84 meshes with the drive gear 31 and transmits the rotation of the handle 2 to the carrier of the second planetary reduction mechanism 28.

The reduction ratio from the third gear member 84 to the second gear member 83 is approximately “1”.

  The drag mechanism 29 has a drag washer 37 and a star drag 3 for adjusting the drag force. The drag mechanism 29 is provided to brake the rotation of the spool in the line feeding direction and prevent the fishing line from being cut.

  The level wind mechanism 22 includes a screw shaft 53 whose both ends are rotatably supported by the first side plate 7 a and the second side plate 7 b, and a fishing line guide 54 that engages with the screw shaft 53. An intersecting spiral groove 53 a is formed on the outer peripheral surface of the screw shaft 53. A driven gear 55 connected to the spool drive mechanism 13 is attached to the right end of the screw shaft 53 in FIG. The fishing line guide 54 is guided along the axial direction of the screw shaft 53. The fishing line guide 54 engages with the spiral groove 53 a of the screw shaft 53, and reciprocates along the screw shaft 53 by the rotation of the screw shaft 53. As a result, the fishing line is wound on the spool 10 substantially uniformly in conjunction with the rotation of the spool 10 in the line winding direction.

<Reel control system configuration>

The spool sensor 63 is provided to detect the rotation speed, rotation direction, and rotation speed of the spool 10. The spool sensor 63 has two magnetic force detection elements that can detect the magnetic force of a magnet (not shown), such as a Hall element or a reed switch. The magnet rotates in conjunction with the rotation of the spool 10, and the two magnetic force detection elements are arranged side by side in the rotation direction of the magnet. The spool sensor 63 can detect the rotation direction of the spool 10 depending on which magnetic force detecting element detects the magnet first. The spool counter 64 counts pulses output from the spool sensor 63. From the output of the spool counter 64, it is possible to detect the number of rotations X of the spool 10 from the beginning of winding and the rotation speed of the spool 10.

  The buzzer 65 is provided for various notifications by a water depth display or the like. The motor driving circuit 66 is provided to drive the motor 12 at a constant speed or a constant tension by pulse width modulation control using a duty ratio. The motor drive circuit 66 includes a current detection unit 66 a that detects a current flowing through the motor 12. The current detection unit 66a is an example of a torque detection unit. The storage unit 67 is configured by a rewritable nonvolatile memory such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) and a flash memory, for example.

  As shown in FIG. 6, the storage unit 67 stores a display data storage area 67a 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.

In addition, a data storage area 67e is provided.

  The rotation data storage area 67c stores an upper limit speed Vsc and an upper limit value Vsc1 and a lower limit value Vsc2 of the upper limit speed Vsc for each stage number SC in the constant speed mode. For example, when the stage number SC is the first speed, the upper limit speed Vsc = 257 rpm, when the second speed is Vsc = 369 rpm, when the third speed is Vsc = 503 rpm, when the fourth speed is Vsc = 665 rpm, when the fifth speed is Vsc = Each 1000 rpm is stored. The upper limit value Vsc1 and the lower limit value Vsc2 are set in a range of ± 10% of the upper limit speed Vsc.

  The rotation data storage area 67c stores, as current values, the upper limit torque Tsc and the upper limit value Tsc1 and the lower limit value Tsc2 for each stage number SC in the constant tension mode, for example, at the maximum spool diameter SDM. For example, when the stage number SC is 1 stage, the upper limit torque is a current value Tsc = 2A, when the stage 2 is, Tsc = 3.5A, when stage 3 is Tsc = 5A, when stage 4 is Tsc = 6.5A. , Tsc = 8A is stored in the case of 5 stages. The upper limit value Tsc1 and the lower limit value Tsc2 of the upper limit torque Tsc are corrected by the bobbin diameter SD at the spool rotation speed X in the motor current control described later, and the upper limit value Qsc1 (Qsc1 = Tsc1 × ( SD / SDM)) and lower limit value Qsc2 (Qsc2 = Tsc2 × (SD / SDM)). The spool diameter SD is obtained by dividing the yarn length Y per one spool rotation at the spool rotation speed X by π (SD = Y / π). The upper limit value Qsc1 and the lower limit value Qsc2 are set in a range of ± 10% of the upper limit tension Qsc.

  The rotation data storage area 67c stores the immediately preceding and latest ones of the first duty ratio D1 and the second duty ratio D4.

  The tension information storage area 67d stores ten levels of tension information “0” to “9” displayed in the constant speed mode or the constant tension mode. The nine-stage tension information displayed in the constant speed mode or the constant tension mode is the tension that actually acts on the fishing line as described above. An example is shown in FIG. For example, when the tension information is “1”, the tension is 0.3 kg-1.5 kg, and when the tension information is “9”, the tension is 8.5 kg or more. The tension information storage area 67d stores a correction current value (correction torque Td1) detected immediately before the current value (torque Td) detected by the current detection unit 66a most recently. The stored correction torque Td1 is used to correct tension information in the tension display area 61c.

  The other data storage area 67e stores various data relating to the yarn length. For example, the ship edge stop position is stored.

  As shown in FIG. 5, the reel control unit 60 includes a motor control unit 69 that controls the motor 12 and a display control unit 70 that controls the display 61 as functional configurations realized by software. . The motor control unit 69 has a first motor control unit 71 that controls the spool 10 at a constant speed for each stage number SC, a second motor control unit 72 that controls the tension acting on the fishing line constant for each stage number SC, and control switching. Part 73. The control switching unit 73 performs switching control between constant speed control by the first motor control unit 71 and constant tension control by the second motor control unit 72.

  The display control unit 70 includes a water depth display unit 74 that displays the water depth in the water depth display region 61a, and a tension display unit 75 that displays tension information in the tension display region 61c. The tension display unit 75 includes a tension detection unit 76, a drag operation detection unit 77, and a tension correction unit 78. The tension detection unit 76 includes a torque detection unit 79 that detects torque acting on the spool 10 based on the current value detected by the current detection unit 66a, a bobbin diameter acquisition unit 80, and a tension calculation unit 81. The bobbin diameter acquisition unit 80 calculates the yarn length Y per one rotation of the spool at that time by the following equation (1) based on the rotation speed X detected by the spool sensor 63. A yarn winding diameter SD is obtained by dividing the yarn length Y by π. The tension calculator 81 calculates the tension acting on the fishing line wound around the spool 10 by multiplying the detected torque by the spool diameter SD.

  The drag operation detection unit 77 detects whether or not the spool mechanism 29 described later operates and the spool 10 slips. When the first duty ratio D1 or the second duty ratio D4, which will be described later, increases by 10% or more of the current value per predetermined time (for example, 0.5 seconds to 1.5 seconds), the drag operation detection unit 77 performs drag mechanism 29. Is operated to determine that the spool 10 is slipping.

  When the drag operation detection unit 77 detects that the drag mechanism 29 has been operated, the tension correction unit 78 displays ten levels of tension information from “0” to “9” displayed in the tension display area 61c. Instead of the tension information corresponding to the detected tension, the drag operation detection unit 77 corrects the tension information before detecting the operation of the drag mechanism 29. For example, even if the drag operation detection unit 77 detects the operation of the drag mechanism 29 before the tension information is “3” in 10 stages, and then the drag mechanism 29 operates to obtain the tension information corresponding to “6”. In the tension display area 61c, “3” is displayed instead of “6”.

  The tension display unit 75 displays the tension information corresponding to the calculated or corrected tension T in the tension display area 61 c of the display device 61.

<Control operation of reel control unit>
The control operation of the reel control unit 60 will be described based on the flowcharts shown in FIGS. Note that the flowcharts shown in FIGS. 7 to 12 are examples of the control procedure, and the control procedure of the present invention is not limited to this.

  In the present invention, the yarn length L is calculated utilizing the fact that the relationship between the yarn length Y per spool rotation and the spool rotation speed X can be approximated to a linear line.

  It is assumed that the fishing line whose thickness and total length are unknown is wound around the spool 10 in a layered manner from the bobbin diameter Bmm, and all the fishing lines have been wound by c rotation. Next, when the Smm fishing line is unwound from that state, it is assumed that the spool 10 has rotated d times.

  Now, since the relationship between the spool rotation speed X and the yarn length Y per spool rotation can be defined by a linear line when the spool rotation speed X is taken on the horizontal axis and the thread length per spool rotation is taken on the vertical axis, If the slope is A, it can be expressed by the following formula.

Y = AX + Bπ (1)
The yarn length Y is calculated by obtaining the slope A and the intercept Bπ in the above equation (1).

  Specifically, the slope A of the linear straight line can be obtained from the following formula using four data, that is, the feeding length S, the body diameter B, the spool rotation speed c, and the feeding rotation speed d.

A = 2 (S−Bπd) / d (2c−d)
For example, when the spool 10 has finished winding at 2000 revolutions from the beginning of winding, and the spool has rotated 60 meters when it is unwound from there, if the spool diameter of the spool 10 is 30 mm, the slope A of the linear straight line Is as follows.

A = 2 (10000-94.2 * 60) / 60 (2 * 2000-60) (2)
= 0.0368
Then, if an approximated straight line with an inclination A and an intercept Bπ can be determined, the primary line is integrated for each rotation of the spool (area calculation process), for example, the yarn length L1 for each rotation of the spool from the beginning of winding to the end of winding. Find ~ LN. Then, the water depth LX at the spool rotation speed r at the end of winding is set to “0”, and the relationship between the water depth LX (= LN) from the start of winding to the spool rotation speed X and the spool rotation speed X is calculated. For example, it is stored in the yarn length data storage area 67b in a map format (LX = MAP (X)).

  When the spool 10 is rotated during actual fishing, the thread length LN is read from the map of the storage unit 67 based on the spool rotational speed X detected by the spool sensor 63 at that time, and the water depth (fishing line) is set based on the read thread length LN. The water depth at the tip is displayed on the display 61.

  When the electric reel is connected to an external power source via a power cord, initial setting is performed in step S1 of FIG. In this initial setting, the count value of the spool counter 64 is reset, various variables and flags are reset, the motor control mode is set to the speed mode, and the display mode is set from the top. The mode from the top is a mode for displaying the water depth from the water surface in the water depth display area 61a.

  In step S2, display processing such as water depth display on the display 61 is performed. The display process will be described later in detail. In step S3, it is determined whether any switch of the operation key unit 62 or the adjustment lever 5 is operated. In step S4, it is determined whether or not the spool 10 is rotating. This determination is made based on the output of the spool sensor 63. In step S5, it is determined whether any other command or input has been made.

  If any switch of the operation key unit 62 or the adjustment lever 5 is operated, the process proceeds from step S3 to step S6. In step S6, switch input processing is executed. If the rotation of the spool 10 is detected, the process proceeds from step S4 to step S7. In step S7, each operation mode process is executed. If any other command or input is made, the process proceeds from step S5 to step S8 to execute other processes.

  In the switch input process of step S6, it is determined whether or not the adjustment lever 5 is pressed in step S11 of FIG. In step S12, it is determined whether or not the motor control selection switch SW1 has been pressed. In step S13, it is determined whether or not another switch has been operated.

  If it is determined that the adjustment lever 5 has been operated, the process proceeds from step S11 to step S15. In step S15, the step number SC of the adjustment lever 5 is fetched. In step S16, it is determined whether or not the stage number SC of the adjustment lever 5 is “0”. When the number SC of the adjustment lever 5 is “0”, the process proceeds to step S17 and the motor 12 is turned off. When the number SC of the adjustment lever 5 is not “0”, the process proceeds from step S16 to step S18. In step S18, it is determined whether or not the motor control mode is a constant speed mode. When in the constant speed mode, the process proceeds to step S19, where spool speed control is performed to control the motor 12 so that the speed corresponds to the number of stages SC of the adjusting lever 5, and the process proceeds to step S12. When it is not in the constant speed mode, the process proceeds from step S18 to step S20, the motor 12 controls the motor 12 so that the tension acting on the fishing line becomes a tension corresponding to the number of stages SC of the adjusting lever 5, and the process proceeds to step S12. .

  In the switch input process of step S6, it is determined whether or not the adjustment lever 5 has been operated in step S15 of FIG. In step S16, it is determined whether or not the menu switch SW1 has been pressed for 3 seconds or longer. In step S17, it is determined whether other switches have been operated. The other switch operations include the normal operation of the menu switch SW1, the determination switch SW2, the memo switch SW3, and the like.

  When the motor control selection switch SW1 is operated, the process proceeds from step S12 to step S21. In step S21, it is determined whether or not the control mode of the motor 12 is a constant speed mode. When in the constant speed mode, the process proceeds from step S21 to step S22, and the control mode is set to the constant tension mode. When not in the constant speed mode but in the constant tension mode, the process proceeds from step S21 to step S23, and the control mode is set to the constant speed mode. When these processes are completed, the process proceeds to step S13.

  When another switch input is made, the process proceeds from step S13 to step S24, for example, other switch input processing such as changing from the bottom to the mode or setting other modes is performed, and the process returns to the main routine shown in FIG. .

  In the spool speed control process in step S19, the motor 12 is controlled so that the rotation speed of the spool 10 becomes the upper limit speed Vsc set for each stage number SC. The upper limit speed Vsc is corrected by the spool diameter of the spool 10, and actually the motor 12 is controlled so that the fishing line winding speed wound around the spool 10 is constant.

  In the spool speed control process, the number of stages SC set by the adjustment lever 5 in step S31 of FIG. 9 and the rotation speed Vd of the spool 10 calculated by the output of the spool sensor 41 are fetched. In step S32, the upper limit value Vsc1 and the lower limit value Vsc2 of the upper limit speed Vsc stored in the rotation data storage area 67c are read. In step S33, it is determined whether or not the speed Vd of the spool 10 is less than the lower limit value Vsc2 of the upper limit speed Vsc corresponding to the stage number SC. In step S43, it is determined whether or not the speed Vd of the spool 10 exceeds the upper limit value Vsc1 of the upper limit speed Vsc corresponding to the number of stages SC. When the speed control is performed, the upper limit value Vsc1 and the lower limit value Vsc2 of the upper limit speed Vsc are provided for each stage SC because the speed varies between the upper limit value Vsc1 and the lower limit value Vsc2. This is because the ratio does not change and the wowing in which the duty ratio fluctuates frequently does not occur, and the feedback control is stabilized.

  When the speed Vd is less than the lower limit value Vsc2, the process proceeds from step S33 to step S35. In step S35, the current first duty ratio D1 is captured. The first duty ratio D1 is stored every time the setting is changed in the rotation data storage area 67c. Further, the maximum value DUsc and the minimum value DLsc are set in the rotation data storage area 52 for each stage number SC. When the stage number SC is initially set, for example, the first duty ratio D1 = ((DUsc + DLsc) in the middle thereof. / 2). In step S36, it is determined whether or not the current first duty ratio D1 exceeds the set maximum value DUsc. When exceeding, the process proceeds to step S38, and the maximum value DUsc is set to the first duty ratio D1. If not, the process proceeds from step S36 to step S37, the first duty ratio D1 is increased by a predetermined increment DI (for example, 1%), and the process proceeds to step S34. The duty ratio of the maximum number of stages (SC = 31) is set to 100%, but the maximum value DUsc is set to 85% or less for the maximum number of stages (SC = 1 to 30) before that. ing.

  When the speed V exceeds the upper limit value Vsc1, the process proceeds from step S34 to step S39, and the current first duty ratio D1 is captured. The first duty ratio D1 is the same as that in step S35. In step S40, it is determined whether or not the current first duty ratio D1 is below the set minimum number DLsc. If it is below, the process proceeds to step S42 and the minimum value DLsc is set to the first duty ratio D1. If not, the process proceeds from step S40 to step S41, the first duty ratio D1 is decreased by a predetermined decrement DI (for example, 1%), and the process returns to the switch input process.

  In the motor current control process in step S20, the step number SC set by the adjustment lever 5 in step S51 in FIG. In step S52, the upper limit value Tsc1 and the lower limit value Tsc2 of the upper limit torque Tsc of the captured stage number SC are read from the rotation data storage area 67c. In step S53, an upper limit value Qsc1 and a lower limit value Qsc2 of the upper limit tension Qsc obtained by correcting the upper limit value Tsc1 and lower limit value Tsc2 of the read upper limit torque Tsc with the bobbin diameter SD are calculated. This calculation method is as described above. In step S54, the detected torque Td acquired in step S51 is divided by the spool diameter SD calculated from the spool rotational speed X at that time (Qd = Td / SD) to calculate the detected tension Qd. In step S55, it is determined whether or not the detected tension Qd is less than the lower limit value Qsc2 of the upper limit tension Qs corresponding to the stage number SC. In step S56, it is determined whether or not the tension Qd exceeds the upper limit value Qsc1 of the upper limit tension Qs according to the stage number SC. If any determination is “NO”, the process returns to the switch input process.

  When the tension control is performed, the lower limit value Qsc2 and the upper limit value Qsc1 of the upper limit tension Ts are provided for each stage SC. The tension varies between the two tensions Qsc1 and Qsc2 as in the constant speed mode. In this case, the duty ratio does not change, so that wouling in which the duty ratio fluctuates frequently does not occur, and the feedback control is stabilized.

  If the tension Qd is less than the lower limit Qsc2, the process proceeds from step S55 to step S57. In step S57, the current second duty ratio D4 is captured. The second duty ratio D4 is stored every time the setting is changed in the rotation data storage area 67c. In step S58, the second duty ratio D4 is increased by a predetermined increment DI (for example, 1%), and the process proceeds to step S56. This is continued until the tension Qd exceeds the lower limit value Qsc2.

  When the tension Qd exceeds the upper limit value Qsc1, the process proceeds from step S56 to step S59, and the current second duty ratio D4 is captured. The second duty ratio D4 is the same as that in step S57. In the next step S60, the second duty ratio D4 is reduced by a predetermined decrement DI (for example, 1%), and the process returns to the switch input process. This is continued until the tension Qd falls below the upper limit value Qsc1.

  In each operation mode process in step S10, it is determined in step S61 in FIG. 11 whether or not the rotation direction of the spool 10 is the yarn feeding direction. This determination is made based on which one of the magnetic force detection elements of the spool sensor 63 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 S61 to step S62. In step S62, every time the spool rotational speed X decreases, the data stored in the thread length data storage area 67b is read from the spool rotational speed X to calculate the water depth (released thread length) LX. This water depth LX is displayed in the display process of step S2. In step S63, 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 67a of the storage unit 67 by long pressing the motor control selection switch SW1 when the device reaches the shelf or the bottom. In step S64, 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 S63 to step S65, and the buzzer 65 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 S64 to step S66, 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 S61 to step S67. In step S67, the data stored in the yarn length data storage area 67b is read from the spool rotational speed X to calculate the water depth LX. This water depth LX is displayed in the display process of step S2.

  In step S68, it is determined whether or not the device has reached the ship edge stop position. When the device is 689, the buzzer 65 is sounded to notify that the device is on the shore. In step S70, 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. If it has not been wound up to the ship edge stop position, it returns to the main routine.

  In the display process of step S2, the step number SC of the adjustment lever 5, the detected torque Td, and the spool rotation number X are fetched in step S71 of FIG. In step S72, the first duty ratio D1 and the second duty ratio D3 are read from the rotation data storage area 67c of the storage unit 67, and the correction torque Td1 is read from the tension information storage area 67d. Further, the current yarn length LX at the current spool rotational speed X is read from the yarn length data storage area 67b. In step S73, the detected torque Td and the corrected torque Td1 are corrected with the current pincushion diameter SD to calculate the detected tension Qd and the corrected tension Qd1. In step S74, it is determined whether or not the drag mechanism 29 is activated. This determination is made by paying attention to the fact that the duty ratio increases abruptly when the drag mechanism 29 operates in the constant speed mode and the constant tension mode.

  FIG. 14 shows an example of a change in current value when the drag mechanism 209 is operated in the constant speed mode. In FIG. 14, the vertical axis represents the value of the current flowing through the motor 12, and the horizontal axis represents the tension acting on the fishing line. The set value of the drag mechanism 29 is 4 Kgf, and the number of steps of the adjustment lever 5 is “5”.

  In the constant speed mode, when the drag mechanism 29 operates and the spool 10 slides with respect to the motor 12, the speed of the spool 10 becomes slower than the target speed, so that the duty ratio is increased. When the drag setting of the drag mechanism 29 is 4 kgf, the spool 10 starts to slide with respect to the motor 12 when the tension exceeds 4 kgf. At this time, the current value corresponding to the amount consumed by the slip increases, but the motor control means increases the duty ratio in order to rotate the spool 10 at the set speed. When the display of the tension information is not corrected due to the increase in the current value, the tension information rapidly increases as shown by a broken line in FIG. However, since the drag mechanism 29 is in operation, the tension actually acting on the fishing line is 4 Kgf, so the tension information is preferably displayed as “4”. Therefore, in order to ignore the increase in the current value caused by the slippage of the drag mechanism 29, tension information corresponding to the tension Qd1 immediately before the drag mechanism 29 operates is displayed on the display 61.

  In the constant tension mode, the upper limit value of the current value is limited for each stage number SC. If the drag mechanism 29 is not activated, almost the actual tension is displayed as tension information. When the set tension is equal to or higher than the drag setting, for example, 6 kgf, and a tension exceeding the drag setting value, for example, 4 kgf, the drag mechanism 29 is activated. At this time, the tension actually acting on the fishing line is the drag set value of 4 kgf. However, when the tension information is not corrected, the maximum “6” is displayed due to the sliding of the drag mechanism 29. When the drag mechanism 29 is not operating, a current having a current value that outputs a torque corresponding to the tension flows to the motor, and tension information corresponding to the current value is displayed. When the drag mechanism 29 is actuated, for example, a current value corresponding to the amount consumed by slipping of the drag mechanism 29 is added to a current value that outputs a torque corresponding to a tension of 4 Kgf, and the current value changes abruptly. When the drag mechanism 29 operates in this way, the current value increases, but does not reach a current value that outputs a torque commensurate with the set tension. Therefore, the motor control means increases the duty ratio to approach the set value. The operation of the drag mechanism 29, that is, the slippage of the drag washer 37 is detected based on the increase in the duty ratio.

  If it is determined that the drag mechanism 29 is activated, the process proceeds from step S74 to step S75. In step S75, the detected detection tension Qd is corrected to the correction tension Qd1, and the process proceeds to step S76. The corrected tension Qd1 is a detected tension before the drag mechanism 29 is activated. If it is determined in step S74 that the drag is not operating, the process proceeds to step S76.

  In step S76, tension information in which the value of the tension Qd is applied to any of the ten levels is displayed in the tension display area 61c of the display 61. Note that the tension Qd may be displayed as it is as the tension information. In step S77, the water depth LX of the device is displayed in the water depth display area 61a. In step S78, the stage number SC is displayed in the stage number display area 61b. In step S79, other information such as the motor control mode is displayed.

  Here, when fishing, when the drag mechanism 29 is activated to detect that the spool 10 slips with respect to the motor 12, the tension correction unit 78 corrects the tension Qd detected by the tension detection unit 76. To do. When the tension Qd is corrected, the corrected tension is displayed on the display 61 instead of the detected tension. Here, when the drag mechanism 29 is operated and the spool 10 slips, the tension is corrected. Therefore, even if the drag mechanism 29 is operated, fluctuations in the display of the tension can be suppressed.

<Features>
The above embodiment can be expressed as follows.

  (A) The reel control system 58 has a drag mechanism 29 and displays the tension acting on the fishing line wound around the spool 10 of the electric reel that can be driven by the motor 12. The reel control system 58 includes a display 61, a current detection unit 66a, a tension detection unit 76, a drag operation detection unit 77, a tension correction unit 78, a tension display unit 75, and a motor control unit 69. ing. The current detector 66 a detects the value of the current flowing through the motor 12. The tension detector 76 detects the tension based on the current value detected by the current detector 66a. The drag operation detector 77 detects whether or not the drag mechanism 29 is operated and the spool 10 is slipping with respect to the motor 12. When the drag operation detection unit 77 determines that the drag mechanism 29 has been operated, the tension correction unit 78 corrects the detection result of the tension detection unit 76. The tension display unit 75 displays information according to the detected tension, and when the detection result is corrected by the tension correction unit 78, displays information according to the corrected tension on the display 61. The unit 69 controls the motor 12 in a plurality of stages.

  In the reel control system 58, when the drag mechanism 29 is operated to detect that the spool 10 has slipped with respect to the motor 12 during fishing, the tension correction unit 78 detects the tension detection unit 76. Correct the tension. When the tension is corrected, the corrected tension is displayed on the display 61 instead of the detected tension. Here, when the drag mechanism 29 is activated and the spool 10 slips, the tension is corrected. Therefore, even if the drag mechanism 29 is operated, fluctuations in the display of the tension can be suppressed.

  (B) In the reel control system 58, the tension detection unit 76 includes a torque detection unit 79, a bobbin diameter acquisition unit 80, and a tension calculation unit 81. The torque detector 79 detects the torque Td acting on the spool 10 based on the current value detected by the current detector 66a. The bobbin diameter acquisition unit 80 obtains the bobbin diameter SD of the fishing line wound around the spool 10. The tension calculator 81 calculates the tension Qd by correcting the torque Td detected by the torque detector 79 with the bobbin diameter SD.

  In this case, the torque Td detected by the current value flowing through the motor 12 is corrected by the pincushion diameter SD and the tension Qd is calculated, so that the accuracy of the displayed tension Qd is improved even if the pincushion diameter SD changes. .

  (C) In the reel control system 58, the drag operation detection unit 77 determines that the drag mechanism 29 is activated when the current value detected by the current detection unit 66a rises by a predetermined value or more per time.

  In this case, since it is determined that the drag mechanism 29 is activated when the current value detected by the current detection unit rises by a predetermined value or more per hour, the operation of the drag mechanism 29 can be detected with high accuracy, particularly when the speed of the spool 10 is controlled. .

  (D) The reel control system 58 further includes a spool sensor 63 that detects the rotation speed of the spool 10 and an adjustment lever 5 that can set the rotation speed of the spool 10 in a plurality of stages. The motor control unit 69 includes a first motor control unit 71 that controls the motor 12 so that the rotation speed set by the adjustment lever 5 is obtained with reference to the rotation speed detected by the spool sensor 63. In this case, the rotation speed of the spool 10 can be controlled in a plurality of stages.

  (E) In the reel control system 58, the first motor control unit 71 controls the motor by pulse width modulation control using the duty ratio, and the drag operation detection unit 77 has a duty output by the first motor control unit 782. When the ratio increases by a predetermined value or more per time, it is determined that the drag mechanism 29 is activated.

  In this case, when the spool speed is controlled, the deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  (F) The reel control system 58 further includes an adjustment lever 5 that can set the tension acting on the fishing line in a plurality of stages. The second motor control unit 72 includes a second motor control unit 72 that controls the motor 12 so that the tension set by the adjustment lever 5 with reference to the tension detected by the tension detection unit 76. In this case, the tension acting on the fishing line can be controlled in a plurality of stages.

  (G) In the reel control system 58, the second motor control unit 72 controls the motor 12 by pulse width modulation control using the duty ratio, and the drag operation detection unit 77 is output by the second motor control unit 72. When the duty ratio increases by a predetermined value or more per time, it is determined that the drag mechanism 29 is activated.

  In this case, when the tension of the spool 10 is controlled, a deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  (H) The reel control system 58 further includes a control switching unit 73 capable of switching between speed control by the first motor control unit 71 and tension control by the second motor control unit 72. In this case, constant speed control and constant tension control can be selected according to the type of fishing.

<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 embodiment, the constant tension control and the constant speed control can be switched, but the present invention is not limited to this. For example, only constant speed control may be performed.

  (B) In the above embodiment, the present invention has been described by taking the electric reel in which the motor 12 is disposed in front of the spool 10 as an example, but the present invention is not limited to this. The present invention can also be applied to an electric reel in which a motor is arranged in a spool and an electric reel in which a motor is arranged outside the reel body.

  (C) In the above embodiment, the relationship between the thread length and the spool rotation speed is learned by paying attention to the fact that the relationship between the thread length per spool rotation and the spool rotation speed is a linear function. A yarn length detector may be mounted, or the relationship between the yarn length and the spool rotational speed may be obtained by a quadratic function.

  (D) In the above embodiment, the speed or tension step number is set by the adjustment lever 5, but the speed or tension step number may be set by an operation switch. In this case, the number of steps may be increased or decreased according to the operation time or the number of operations.

  (E) In the embodiment, the operation of the drag mechanism (spool slip) is detected by a sudden increase in the duty ratio, but the present invention is not limited to this. A sensor for detecting the rotational speed of the motor may be provided, and the operation of the drag mechanism may be detected by judging the slippage of the spool from the relationship between the rotational speed of the motor and the rotational speed of the spool. Further, the operation of the drag mechanism may be detected by a rapid increase in the current value. Further, it may be detected from both a change in current value and a change in spool rotation speed. For example, it can be determined that the drag mechanism is apparently operating if the spool rotation speed does not change or the current value is increasing, or if the spool rotation speed is decreasing or rotating in the yarn feeding direction.

  The present invention relates to a control device, and more particularly to a control device for an electric reel that has a drag mechanism and displays tension acting on a fishing line wound around a spool of an electric reel that can be driven by a motor.

  An electric reel having a function of displaying a tension acting on a fishing line is conventionally known (see, for example, Patent Document 1). In the conventional electric reel, when a new fishing line is wound around the spool, the tension is displayed so that the angler can wind the fishing line around the fishing line with a constant tension. The tension is detected based on the detected current value by detecting the current value flowing through the motor.

  Further, an electric reel that controls the winding speed of a spool in a plurality of stages when fishing is conventionally known (see, for example, Patent Document 2). In the conventional electric reel, the motor is controlled by the duty ratio, and the spool speed is controlled in a plurality of stages.

Japanese Patent No. 2885356 Japanese Patent No. 4427126

  In the electric reel capable of controlling the speed of Patent Document 2 in a plurality of stages, it is conceivable to display the tension actually acting on the fishing line by applying the tension display function described in Patent Document 1. However, in the tension display function of Patent Document 1, the tension is displayed by the current value output from the motor. For this reason, when the drag mechanism is operated and the motor rotates in the winding direction, the display of tension is increased according to the current value. However, in reality, since the drag is slipping, the tension is not increased. That is, the tension display becomes larger than the actual value.

  An object of the present invention is to suppress a change in display of tension even when a drag mechanism is operated in an electric reel control device.

Control apparatus for an electric reel according to the invention 1 includes a drag mechanism, a control unit drivable electrostatic kinematic reel motor. The electric reel control device includes a display, a current value detection means, a tension detection means, a drag operation detection means, a tension correction means, a tension display means, and a motor control means. The indicator displays the tension acting on the fishing line wound around the spool. The current value detection means detects a current value flowing through the motor. The tension detection means detects the tension based on the current value detected by the current value detection means. The drag operation detecting means detects whether the drag mechanism is operated and the spool is sliding with respect to the motor. The tension correction unit corrects the detection result of the tension detection unit when the drag operation detection unit determines that the drag mechanism is operated. The tension display means displays information according to the detected tension, and when the detection result is corrected by the tension correction means, displays information according to the corrected tension on the display . The motor control means controls the motor in a plurality of stages.

  In this electric reel control device, when fishing, when the drag mechanism is actuated and it is detected that the spool has slipped with respect to the motor, the tension correcting means corrects the tension detected by the tension detecting means. . When the tension is corrected, the corrected tension is displayed on the display instead of the detected tension. Here, when the drag mechanism is activated and the spool slips, the tension is corrected, so that the fluctuation of the tension display can be suppressed even if the drag mechanism is activated.

  An electric reel control apparatus according to a second aspect of the present invention is the apparatus according to the first aspect, wherein the tension detecting means includes torque detecting means, pincushion diameter acquiring means, and tension calculating means. The torque detecting means detects torque acting on the spool based on the current value detected by the current value detecting means. The bobbin diameter acquisition means acquires the bobbin diameter of the fishing line wound around the spool. The tension calculating means calculates the tension by correcting the torque detected by the torque detecting means with the acquired bobbin diameter.

  In this case, since the torque detected by the value of the current flowing through the motor is corrected by the bobbin diameter and the tension is calculated, the accuracy of the displayed tension is improved even if the bobbin diameter changes.

  The electric reel control device according to a third aspect of the present invention is the electric reel motor control device according to the first or second aspect, wherein the drag operation detecting means is configured such that when the current value detected by the current value detecting means rises above a predetermined value per time, It is determined that the drag mechanism has been activated.

  In this case, when the current value detected by the current value detecting means rises by a predetermined value or more per time, it is determined that the drag mechanism has been operated. Therefore, the operation of the drag mechanism can be detected with high accuracy, particularly when the speed of the spool is controlled.

  A control device for an electric reel according to a fourth aspect of the invention is the device according to any one of the first to third aspects, wherein a speed detecting means for detecting the rotational speed of the spool and a speed setting means capable of setting the rotational speed of the spool in a plurality of stages. And further comprising. The motor control means includes first motor control means for controlling the motor so that the rotation speed set by the speed setting means is obtained by referring to the rotation speed detected by the speed detection means. In this case, the rotation speed of the spool can be controlled in a plurality of stages.

  An electric reel control device according to a fifth aspect of the present invention is the device according to the fourth aspect, wherein the first motor control means controls the motor by pulse width modulation control using a duty ratio, and the drag operation detecting means is the first motor. When the duty ratio output by the control means increases by a predetermined value or more per time, it is determined that the drag mechanism is activated.

  In this case, when the spool speed is controlled, the deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  An electric reel control device according to a sixth aspect of the present invention is the device according to the fourth or fifth aspect, further comprising tension setting means capable of setting the tension acting on the fishing line in a plurality of stages. The motor control means has second motor control means for controlling the motor so as to be the tension set by the tension setting means with reference to the tension detected by the tension detection means. In this case, the tension acting on the fishing line can be controlled in a plurality of stages.

  The control device for an electric reel according to a seventh aspect of the present invention is the device according to the sixth aspect, wherein the second motor control means controls the motor by pulse width modulation control using a duty ratio, and the drag operation detecting means is the second motor. When the duty ratio output by the control means increases by a predetermined value or more per time, it is determined that the drag mechanism is activated.

  In this case, when the spool tension is controlled, a deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  An electric reel control device according to an eighth aspect of the present invention is the device according to the sixth or seventh aspect, further comprising control switching means capable of switching between speed control by the first motor control means and tension control by the second motor control means. In this case, constant speed control and constant tension control can be selected according to the type of fishing.

  According to the present invention, when the drag mechanism is activated and the spool slips, the tension is corrected. Therefore, even if the drag mechanism is operated, fluctuations in the display of the tension can be suppressed.

The ratchet wheel 35 is prohibited from rotating in the yarn feeding direction by a ratchet claw (not shown). The proximal end of the handle shaft 30 is rotatably supported by a bearing (not shown) to the second side plate 7b. The handle shaft 30 is supported by the first boss 8c of the second side cover 8b by a roller-type second one-way clutch 36. The handle shaft 30 is prohibited from rotating in the yarn feeding direction by the first one-way clutch 34. The drag mechanism 29 can be operated by prohibiting the rotation of the handle shaft 30 in the yarn feeding direction. The second one-way clutch 36 quickly prohibits the rotation of the handle shaft 30 in the yarn unwinding direction.

  The drive gear 31 is rotatably mounted on the handle shaft 30. The drive gear 31 is pressed by the drag washer 37. The drive gear 31 is braked for rotation in the yarn feeding direction by the drag mechanism 29. As a result, the rotation of the spool 10 in the yarn unwinding direction is braked.

  The rotation data storage area 67c stores an upper limit speed Vsc and an upper limit value Vsc1 and a lower limit value Vsc2 of the upper limit speed Vsc for each stage number SC in the constant speed mode. For example, when the stage number SC is the first speed, the upper limit speed Vsc = 257 rpm, when the second speed is Vsc = 369 rpm, when the third speed is Vsc = 503 rpm, when the fourth speed is Vsc = 665 rpm, when the fifth speed is Vsc = Each 1000 rpm is stored.

  The rotation data storage area 67c stores the immediately preceding and latest ones of the first duty ratio D1 and the second duty ratio D4.

The tension information storage area 67d stores ten levels of tension information “0” to “9” displayed in the constant speed mode or the constant tension mode. Ten- stage tension information displayed in the constant speed mode or the constant tension mode is the tension that actually acts on the fishing line as described above. An example is shown in FIG. For example, if the tension information is "1", a tension of up to 0.3kg f -1.5kg f, if the tension information is "9", which is more tension 8.5 kg f. The tension information storage area 67d stores a correction current value (correction torque Td1) detected immediately before the current value (torque Td) detected by the current detection unit 66a most recently. The stored correction torque Td1 is used to correct tension information in the tension display area 61c.

  The other data storage area 67e stores various data relating to the yarn length. For example, the ship edge stop position is stored.

As shown in FIG. 5, the reel control unit 60 includes a motor control unit 69 that controls the motor 12 and a display control unit 70 that controls the display 61 as functional configurations realized by software. . The motor control unit 69 has a first motor control unit 71 that controls the spool 10 at a constant speed for each stage number SC, a second motor control unit 72 that controls the tension acting on the fishing line constant for each stage number SC, and control switching. Part 73. Control switching unit 73, a constant speed control by the first motor control unit 71, and the tension constant control by the second motor control unit 72, controls switching to apply.

  The display control unit 70 includes a water depth display unit 74 that displays the water depth in the water depth display region 61a, and a tension display unit 75 that displays tension information in the tension display region 61c. The tension display unit 75 includes a tension detection unit 76, a drag operation detection unit 77, and a tension correction unit 78. The tension detection unit 76 includes a torque detection unit 79 that detects torque acting on the spool 10 based on the current value detected by the current detection unit 66a, a bobbin diameter acquisition unit 80, and a tension calculation unit 81. The bobbin diameter acquisition unit 80 calculates the yarn length Y per one rotation of the spool at that time by the following equation (1) based on the rotation speed X detected by the spool sensor 63. A yarn winding diameter SD is obtained by dividing the yarn length Y by π. The tension calculator 81 calculates the tension acting on the fishing line wound around the spool 10 by multiplying the detected torque by the spool diameter SD.

  The drag operation detection unit 77 detects whether or not the spool mechanism 29 described later operates and the spool 10 slips. When the first duty ratio D1 or the second duty ratio D4, which will be described later, increases by 10% or more of the current value per predetermined time (for example, 0.5 seconds to 1.5 seconds), the drag operation detection unit 77 performs drag mechanism 29. Is operated to determine that the spool 10 is slipping.

  When the drag operation detection unit 77 detects that the drag mechanism 29 has been operated, the tension correction unit 78 displays ten levels of tension information from “0” to “9” displayed in the tension display area 61c. Instead of the tension information corresponding to the detected tension, the drag operation detection unit 77 corrects the tension information before detecting the operation of the drag mechanism 29. For example, even if the drag operation detection unit 77 detects the operation of the drag mechanism 29 before the tension information is “3” in 10 stages, and then the drag mechanism 29 operates to obtain the tension information corresponding to “6”. In the tension display area 61c, “3” is displayed instead of “6”.

  The tension display unit 75 displays the tension information corresponding to the calculated or corrected tension T in the tension display area 61 c of the display device 61.

<Control operation of reel control unit>
The control operation of the reel control unit 60 will be described based on the flowcharts shown in FIGS. Note that the flowcharts shown in FIGS. 7 to 12 are examples of the control procedure, and the control procedure of the present invention is not limited to this.

  In the present invention, the yarn length L is calculated utilizing the fact that the relationship between the yarn length Y per spool rotation and the spool rotation speed X can be approximated to a linear line.

  It is assumed that the fishing line whose thickness and total length are unknown is wound around the spool 10 in a layered manner from the bobbin diameter Bmm, and all the fishing lines have been wound by c rotation. Next, when the Smm fishing line is unwound from that state, it is assumed that the spool 10 has rotated d times.

  Now, since the relationship between the spool rotation speed X and the yarn length Y per spool rotation can be defined by a linear line when the spool rotation speed X is taken on the horizontal axis and the thread length per spool rotation is taken on the vertical axis, If the slope is A, it can be expressed by the following formula.

Y = AX + Bπ (1)
The yarn length Y is calculated by obtaining the slope A and the intercept Bπ in the above equation (1).

  Specifically, the slope A of the linear straight line can be obtained from the following formula using four data, that is, the feeding length S, the body diameter B, the spool rotation speed c, and the feeding rotation speed d.

A = 2 (S−Bπd) / d (2c−d)
For example, when the spool 10 has finished winding at 2000 revolutions from the beginning of winding, and the spool has rotated 60 meters when it is unwound from there, if the spool diameter of the spool 10 is 30 mm, the slope A of the linear straight line Is as follows.

A = 2 (10000-94.2 * 60) / 60 (2 * 2000-60) (2)
= 0.0368
Then, if an approximated straight line with an inclination A and an intercept Bπ can be determined, the primary line is integrated for each rotation of the spool (area calculation process), for example, the yarn length L1 for each rotation of the spool from the beginning of winding to the end of winding. Find ~ LN. Then, the water depth LX at the spool rotation speed r at the end of winding is set to “0”, and the relationship between the water depth LX (= LN) from the start of winding to the spool rotation speed X and the spool rotation speed X is calculated. For example, it is stored in the yarn length data storage area 67b in a map format (LX = MAP (X)).

  When the spool 10 is rotated during actual fishing, the thread length LN is read from the map of the storage unit 67 based on the spool rotational speed X detected by the spool sensor 63 at that time, and the water depth (fishing line) is set based on the read thread length LN. The water depth at the tip is displayed on the display 61.

  When the electric reel is connected to an external power source via a power cord, initial setting is performed in step S1 of FIG. In this initial setting, the count value of the spool counter 64 is reset, various variables and flags are reset, the motor control mode is set to the speed mode, and the display mode is set from the top. The mode from the top is a mode for displaying the water depth from the water surface in the water depth display area 61a.

  In step S2, display processing such as water depth display on the display 61 is performed. The display process will be described later in detail. In step S3, it is determined whether any switch of the operation key unit 62 or the adjustment lever 5 is operated. In step S4, it is determined whether or not the spool 10 is rotating. This determination is made based on the output of the spool sensor 63. In step S5, it is determined whether any other command or input has been made.

  If any switch of the operation key unit 62 or the adjustment lever 5 is operated, the process proceeds from step S3 to step S6. In step S6, switch input processing is executed. If the rotation of the spool 10 is detected, the process proceeds from step S4 to step S7. In step S7, each operation mode process is executed. If any other command or input is made, the process proceeds from step S5 to step S8 to execute other processes.

  In the switch input process of step S6, it is determined whether or not the adjustment lever 5 is pressed in step S11 of FIG. In step S12, it is determined whether or not the motor control selection switch SW1 has been pressed. In step S13, it is determined whether or not another switch has been operated.

  If it is determined that the adjustment lever 5 has been operated, the process proceeds from step S11 to step S15. In step S15, the step number SC of the adjustment lever 5 is fetched. In step S16, it is determined whether or not the stage number SC of the adjustment lever 5 is “0”. When the number SC of the adjustment lever 5 is “0”, the process proceeds to step S17 and the motor 12 is turned off. When the number SC of the adjustment lever 5 is not “0”, the process proceeds from step S16 to step S18. In step S18, it is determined whether or not the motor control mode is a constant speed mode. When in the constant speed mode, the process proceeds to step S19, where spool speed control is performed to control the motor 12 so that the speed corresponds to the number of stages SC of the adjusting lever 5, and the process proceeds to step S12. When it is not in the constant speed mode, the process proceeds from step S18 to step S20, the motor 12 controls the motor 12 so that the tension acting on the fishing line becomes a tension corresponding to the number of stages SC of the adjusting lever 5, and the process proceeds to step S12. .

  When the motor control selection switch SW1 is operated, the process proceeds from step S12 to step S21. In step S21, it is determined whether or not the control mode of the motor 12 is a constant speed mode. When in the constant speed mode, the process proceeds from step S21 to step S22, and the control mode is set to the constant tension mode. When not in the constant speed mode but in the constant tension mode, the process proceeds from step S21 to step S23, and the control mode is set to the constant speed mode. When these processes are completed, the process proceeds to step S13.

  When another switch input is made, the process proceeds from step S13 to step S24, for example, other switch input processing such as changing from the bottom to the mode or setting other modes is performed, and the process returns to the main routine shown in FIG. .

  In the spool speed control process in step S19, the motor 12 is controlled so that the rotation speed of the spool 10 becomes the upper limit speed Vsc set for each stage number SC. The upper limit speed Vsc is corrected by the spool diameter of the spool 10, and actually the motor 12 is controlled so that the fishing line winding speed wound around the spool 10 is constant.

In the spool speed control process, the number of stages SC set by the adjustment lever 5 in step S31 of FIG. 9 and the rotation speed Vd of the spool 10 calculated from the output of the spool sensor 63 are taken in. In step S32, the upper limit value Vsc1 and the lower limit value Vsc2 of the upper limit speed Vsc stored in the rotation data storage area 67c are read. In step S33, it is determined whether or not the speed Vd of the spool 10 is less than the lower limit value Vsc2 of the upper limit speed Vsc corresponding to the stage number SC. In step S 34, it is determined whether the speed Vd of the spool 10 exceeds the upper limit Vsc1 upper speed Vsc corresponding to the number of stages SC. When the speed control is performed, the upper limit value Vsc1 and the lower limit value Vsc2 of the upper limit speed Vsc are provided for each stage SC because the speed varies between the upper limit value Vsc1 and the lower limit value Vsc2. This is because the ratio does not change and the wowing in which the duty ratio fluctuates frequently does not occur, and the feedback control is stabilized.

When the speed Vd is less than the lower limit value Vsc2, the process proceeds from step S33 to step S35. In step S35, the current first duty ratio D1 is captured. The first duty ratio D1 is stored every time the setting is changed in the rotation data storage area 67c. Further, the maximum value DUsc and the minimum value DLsc are set in the rotation data storage area 62c for each stage number SC. When the stage number SC is initially set, for example, the first duty ratio D1 = ((DUsc + DLsc) in the middle thereof / 2). In step S36, it is determined whether or not the current first duty ratio D1 exceeds the set maximum value DUsc. When exceeding, the process proceeds to step S38, and the maximum value DUsc is set to the first duty ratio D1. If not, the process proceeds from step S36 to step S37, the first duty ratio D1 is increased by a predetermined increment DI (for example, 1%), and the process proceeds to step S34. The duty ratio of the maximum number of stages (SC = 31) is set to 100%, but the maximum value DUsc is set to 85% or less for the maximum number of stages (SC = 1 to 30) before that. ing.

If the velocity V d is greater than the upper limit Vsc1 captures the first duty ratio D1 of the current shifts from step S34 to step S39. The first duty ratio D1 is the same as that in step S35. In step S40, it is determined whether or not the current first duty ratio D1 is below the set minimum number DLsc. If it is below, the process proceeds to step S42 and the minimum value DLsc is set to the first duty ratio D1. If not, the process proceeds from step S40 to step S41, the first duty ratio D1 is decreased by a predetermined decrement DI (for example, 1%), and the process returns to the switch input process.

The motor current control processing in step S20, fetches level SC is set by the adjustment lever 5 at the step S51 in FIG. 10, the torque Td of the detection result of the current detecting portion 66a, and the number of spool rotations X. In step S52, the upper limit value Tsc1 and the lower limit value Tsc2 of the upper limit torque Tsc of the captured stage number SC are read from the rotation data storage area 67c. In step S53, an upper limit value Qsc1 and a lower limit value Qsc2 of the upper limit tension Qsc obtained by correcting the upper limit value Tsc1 and lower limit value Tsc2 of the read upper limit torque Tsc with the bobbin diameter SD are calculated. This calculation method is as described above. In step S54, the detected torque Td acquired in step S51 is divided by the spool diameter SD calculated from the spool rotational speed X at that time (Qd = Td / SD) to calculate the detected tension Qd. In step S55, the detected tension Qd is determined whether the lower limit value below Qsc2 upper tension Qs c corresponding to the number of stages SC. In step S56, it is determined whether the tension Qd exceeds the upper limit Qsc1 upper tension Qs c corresponding to the number of stages SC, one of the determination returns to the switch input process when the "NO".

When the tension control is performed, the lower limit value Qsc2 and the upper limit value Qsc1 of the upper limit tension Qsc are provided for each stage number SC, as in the constant speed mode, the tension varies between the two tensions Qsc1 and Qsc2. In this case, the duty ratio does not change, so that wouling in which the duty ratio fluctuates frequently does not occur, and the feedback control is stabilized.

  If the tension Qd is less than the lower limit Qsc2, the process proceeds from step S55 to step S57. In step S57, the current second duty ratio D4 is captured. The second duty ratio D4 is stored every time the setting is changed in the rotation data storage area 67c. In step S58, the second duty ratio D4 is increased by a predetermined increment DI (for example, 1%), and the process proceeds to step S56. This is continued until the tension Qd exceeds the lower limit value Qsc2.

  When the tension Qd exceeds the upper limit value Qsc1, the process proceeds from step S56 to step S59, and the current second duty ratio D4 is captured. The second duty ratio D4 is the same as that in step S57. In the next step S60, the second duty ratio D4 is reduced by a predetermined decrement DI (for example, 1%), and the process returns to the switch input process. This is continued until the tension Qd falls below the upper limit value Qsc1.

In each operation mode process of Step S 7, the rotation direction of the spool 10 to determine whether the line release direction in step S61 in FIG. 11. This determination is made based on which one of the magnetic force detection elements of the spool sensor 63 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 S61 to step S62. In step S62, every time the spool rotational speed X decreases, the data stored in the thread length data storage area 67b is read from the spool rotational speed X to calculate the water depth (released thread length) LX. This water depth LX is displayed in the display process of step S2. In step S63, 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 67a of the storage unit 67 by long pressing the motor control selection switch SW1 when the device reaches the shelf or the bottom. In step S64, 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 S63 to step S65, and the buzzer 65 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 S64 to step S66, 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 S61 to step S67. In step S67, the data stored in the yarn length data storage area 67b is read from the spool rotational speed X to calculate the water depth LX. This water depth LX is displayed in the display process of step S2.

In step S68, it is determined whether or not the device has reached the ship edge stop position. In step S69 , the buzzer 65 is sounded to notify that the device is on the shore. In step S70, the motor 12 is turned off. As a result, when the fish is caught or when the device is collected and the bait is exchanged, the fish or device is arranged at a position where it can be easily taken. If it has not been wound up to the ship edge stop position, it returns to the main routine.

In the display process of step S2, the step number SC of the adjustment lever 5, the detected torque Td, and the spool rotation number X are fetched in step S71 of FIG. At step S72, the reads in the rotation data storage area 67c of the first duty ratio D1 and the second duty ratio D 4 of the storage unit 67, reads the correction torque Td1 from the tension data storage area 67d. Further, the current yarn length LX at the current spool rotational speed X is read from the yarn length data storage area 67b. In step S73, the detected torque Td and the corrected torque Td1 are corrected with the current pincushion diameter SD to calculate the detected tension Qd and the corrected tension Qd1. In step S74, it is determined whether or not the drag mechanism 29 is activated. This determination is made by paying attention to the fact that the duty ratio increases abruptly when the drag mechanism 29 operates in the constant speed mode and the constant tension mode.

FIG. 14 shows an example of a change in the current value when the drag mechanism 29 is operated in the constant speed mode. In FIG. 14, the vertical axis represents the value of the current flowing through the motor 12, and the horizontal axis represents the tension acting on the fishing line. The set value of the drag mechanism 29 is 4 Kgf, and the number of steps of the adjustment lever 5 is “5”.

  In the constant speed mode, when the drag mechanism 29 operates and the spool 10 slides with respect to the motor 12, the speed of the spool 10 becomes slower than the target speed, so that the duty ratio is increased. When the drag setting of the drag mechanism 29 is 4 kgf, the spool 10 starts to slide with respect to the motor 12 when the tension exceeds 4 kgf. At this time, the current value corresponding to the amount consumed by the slip increases, but the motor control means increases the duty ratio in order to rotate the spool 10 at the set speed. When the display of the tension information is not corrected due to the increase in the current value, the tension information rapidly increases as shown by a broken line in FIG. However, since the drag mechanism 29 is in operation, the tension actually acting on the fishing line is 4 Kgf, so the tension information is preferably displayed as “4”. Therefore, in order to ignore the increase in the current value caused by the slippage of the drag mechanism 29, tension information corresponding to the tension Qd1 immediately before the drag mechanism 29 operates is displayed on the display 61.

  In the constant tension mode, the upper limit value of the current value is limited for each stage number SC. If the drag mechanism 29 is not activated, almost the actual tension is displayed as tension information. When the set tension is equal to or higher than the drag setting, for example, 6 kgf, and a tension exceeding the drag setting value, for example, 4 kgf, the drag mechanism 29 is activated. At this time, the tension actually acting on the fishing line is the drag set value of 4 kgf. However, when the tension information is not corrected, the maximum “6” is displayed due to the sliding of the drag mechanism 29. When the drag mechanism 29 is not operating, a current having a current value that outputs a torque corresponding to the tension flows to the motor, and tension information corresponding to the current value is displayed. When the drag mechanism 29 is actuated, for example, a current value corresponding to the amount consumed by slipping of the drag mechanism 29 is added to a current value that outputs a torque corresponding to a tension of 4 Kgf, and the current value changes abruptly. When the drag mechanism 29 operates in this way, the current value increases, but does not reach a current value that outputs a torque commensurate with the set tension. Therefore, the motor control means increases the duty ratio to approach the set value. The operation of the drag mechanism 29, that is, the slippage of the drag washer 37 is detected based on the increase in the duty ratio.

  If it is determined that the drag mechanism 29 is activated, the process proceeds from step S74 to step S75. In step S75, the detected detection tension Qd is corrected to the correction tension Qd1, and the process proceeds to step S76. The corrected tension Qd1 is a detected tension before the drag mechanism 29 is activated. If it is determined in step S74 that the drag is not operating, the process proceeds to step S76.

  In step S76, tension information in which the value of the tension Qd is applied to any of the ten levels is displayed in the tension display area 61c of the display 61. Note that the tension Qd may be displayed as it is as the tension information. In step S77, the water depth LX of the device is displayed in the water depth display area 61a. In step S78, the stage number SC is displayed in the stage number display area 61b. In step S79, other information such as the motor control mode is displayed.

  Here, when fishing, when the drag mechanism 29 is activated to detect that the spool 10 slips with respect to the motor 12, the tension correction unit 78 corrects the tension Qd detected by the tension detection unit 76. To do. When the tension Qd is corrected, the corrected tension is displayed on the display 61 instead of the detected tension. Here, when the drag mechanism 29 is operated and the spool 10 slips, the tension is corrected. Therefore, even if the drag mechanism 29 is operated, fluctuations in the display of the tension can be suppressed.

<Features>
The above embodiment can be expressed as follows.

(A) The reel control system 58 has a drag mechanism 29 and displays the tension acting on the fishing line wound around the spool 10 of the electric reel that can be driven by the motor 12. The reel control system 58 includes a display 61, a current detection unit 66a, a tension detection unit 76, a drag operation detection unit 77, a tension correction unit 78, a tension display unit 75, and a motor control unit 69. ing. The current detector 66 a detects the value of the current flowing through the motor 12. The tension detector 76 detects the tension based on the current value detected by the current detector 66a. The drag operation detector 77 detects whether or not the drag mechanism 29 is operated and the spool 10 is slipping with respect to the motor 12. When the drag operation detection unit 77 determines that the drag mechanism 29 has been operated, the tension correction unit 78 corrects the detection result of the tension detection unit 76. The tension display unit 75 displays information according to the detected tension, and when the detection result is corrected by the tension correction unit 78, displays information according to the corrected tension on the display 61 . The motor control unit 69 controls the motor 12 in a plurality of stages.

  In the reel control system 58, when the drag mechanism 29 is operated to detect that the spool 10 has slipped with respect to the motor 12 during fishing, the tension correction unit 78 detects the tension detection unit 76. Correct the tension. When the tension is corrected, the corrected tension is displayed on the display 61 instead of the detected tension. Here, when the drag mechanism 29 is activated and the spool 10 slips, the tension is corrected. Therefore, even if the drag mechanism 29 is operated, fluctuations in the display of the tension can be suppressed.

  (B) In the reel control system 58, the tension detection unit 76 includes a torque detection unit 79, a bobbin diameter acquisition unit 80, and a tension calculation unit 81. The torque detector 79 detects the torque Td acting on the spool 10 based on the current value detected by the current detector 66a. The bobbin diameter acquisition unit 80 obtains the bobbin diameter SD of the fishing line wound around the spool 10. The tension calculator 81 calculates the tension Qd by correcting the torque Td detected by the torque detector 79 with the bobbin diameter SD.

  In this case, the torque Td detected by the current value flowing through the motor 12 is corrected by the pincushion diameter SD and the tension Qd is calculated, so that the accuracy of the displayed tension Qd is improved even if the pincushion diameter SD changes. .

  (C) In the reel control system 58, the drag operation detection unit 77 determines that the drag mechanism 29 is activated when the current value detected by the current detection unit 66a rises by a predetermined value or more per time.

  In this case, since it is determined that the drag mechanism 29 is activated when the current value detected by the current detection unit rises by a predetermined value or more per hour, the operation of the drag mechanism 29 can be detected with high accuracy, particularly when the speed of the spool 10 is controlled. .

  (D) The reel control system 58 further includes a spool sensor 63 that detects the rotation speed of the spool 10 and an adjustment lever 5 that can set the rotation speed of the spool 10 in a plurality of stages. The motor control unit 69 includes a first motor control unit 71 that controls the motor 12 so that the rotation speed set by the adjustment lever 5 is obtained with reference to the rotation speed detected by the spool sensor 63. In this case, the rotation speed of the spool 10 can be controlled in a plurality of stages.

(E) In the reel control system 58, the first motor control unit 71 controls the motor by pulse width modulation control using the duty ratio, and the drag operation detection unit 77 has a duty output by the first motor control unit 71. When the ratio increases by a predetermined value or more per time, it is determined that the drag mechanism 29 is activated.

  In this case, when the spool speed is controlled, the deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  (F) The reel control system 58 further includes an adjustment lever 5 that can set the tension acting on the fishing line in a plurality of stages. The second motor control unit 72 includes a second motor control unit 72 that controls the motor 12 so that the tension set by the adjustment lever 5 with reference to the tension detected by the tension detection unit 76. In this case, the tension acting on the fishing line can be controlled in a plurality of stages.

  (G) In the reel control system 58, the second motor control unit 72 controls the motor 12 by pulse width modulation control using the duty ratio, and the drag operation detection unit 77 is output by the second motor control unit 72. When the duty ratio increases by a predetermined value or more per time, it is determined that the drag mechanism 29 is activated.

  In this case, when the tension of the spool 10 is controlled, a deviation between the motor rotation and the spool rotation can be easily detected by the change of the duty ratio.

  (H) The reel control system 58 further includes a control switching unit 73 capable of switching between speed control by the first motor control unit 71 and tension control by the second motor control unit 72. In this case, constant speed control and constant tension control can be selected according to the type of fishing.

<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 embodiment, the constant tension control and the constant speed control can be switched, but the present invention is not limited to this. For example, only constant speed control may be performed.

  (B) In the above embodiment, the present invention has been described by taking the electric reel in which the motor 12 is disposed in front of the spool 10 as an example, but the present invention is not limited to this. The present invention can also be applied to an electric reel in which a motor is arranged in a spool and an electric reel in which a motor is arranged outside the reel body.

  (C) In the above embodiment, the relationship between the thread length and the spool rotation speed is learned by paying attention to the fact that the relationship between the thread length per spool rotation and the spool rotation speed is a linear function. A yarn length detector may be mounted, or the relationship between the yarn length and the spool rotational speed may be obtained by a quadratic function.

  (D) In the above embodiment, the speed or tension step number is set by the adjustment lever 5, but the speed or tension step number may be set by an operation switch. In this case, the number of steps may be increased or decreased according to the operation time or the number of operations.

  (E) In the embodiment, the operation of the drag mechanism (spool slip) is detected by a sudden increase in the duty ratio, but the present invention is not limited to this. A sensor for detecting the rotational speed of the motor may be provided, and the operation of the drag mechanism may be detected by judging the slippage of the spool from the relationship between the rotational speed of the motor and the rotational speed of the spool. Further, the operation of the drag mechanism may be detected by a rapid increase in the current value. Further, it may be detected from both a change in current value and a change in spool rotation speed. For example, it can be determined that the drag mechanism is apparently operating if the spool rotation speed does not change or the current value is increasing, or if the spool rotation speed is decreasing or rotating in the yarn feeding direction.
