[0003] [Patent Document 1] JP 2017-189150 A Summary of the Invention [Problem to be solved by the invention]

[0004] With an electric reel, when the fishing line is gradually wound up by repeatedly lifting the rod and jerking it, the tackle encounters resistance from the water, causing more torque than necessary, and the winding torque can greatly exceed the predetermined value set by the operation unit. Also, when winding up the slack fishing line after a jerking motion, if the handle is rotated in the winding direction to perform a follow-up winding operation, the rotational speed of the spool can greatly exceed the predetermined value set by the operation unit. In such a case, the motor control device of the electric reel stops the motor drive and performs feedback control so that the spool rotational speed or winding torque becomes the predetermined value set by the operation unit, but since the motor drive is temporarily stopped, the user may feel uncomfortable with the motor's behavior.

[0005] An object of the present invention is to improve the operability of jigging operation using an electric reel. [Means for solving the problem]

[0006] A motor control device for an electric reel according to a first aspect of the present invention uses a motor to drive a spool rotatably attached to a reel body. The motor control device includes an operation unit, a speed detection unit, a torque detection unit, and a motor control unit. The operation unit is provided on the reel body. The speed detection unit detects the rotation speed of the spool. The torque detection unit detects the winding torque of the motor. The motor control unit controls the drive output of the motor to a plurality of stages in response to operation of the operation unit. The motor control unit includes a first output mode and a second output mode. The first output mode controls the drive output of the motor so that the rotation speed of the spool is equal to or less than the first set speed when a first time during which the rotation speed of the spool exceeds a first set speed corresponding to a first predetermined stage of the plurality of stages is equal to or greater than a first predetermined time based on the detection result of the speed detection unit. The first output mode limits the drive output of the motor so that the winding torque of the motor is equal to or less than the first set torque when the second time during which the winding torque of the motor exceeds the first set torque corresponding to the first predetermined step is equal to or greater than the second predetermined time based on the detection result of the torque detection unit. The second output mode maintains the drive output of the motor when the first time during which the winding torque of the motor exceeds the first set speed corresponding to the first predetermined step and the second time during which the winding torque of the motor exceeds the first set torque corresponding to the first predetermined step are less than the first predetermined time and the second predetermined time, respectively.

[0007] In this motor control device for an electric reel, in the second output mode of the motor control unit, it is possible to maintain the drive output of the motor when, for example, the rotation speed of the spool and the winding torque of the motor exceed a predetermined value only for a short time. Therefore, when the rod is lifted and a jerk motion is performed while the motor is being driven, it is possible to prevent the drive of the motor from stopping. This improves the operability of the jigging motion using the electric reel.

[0008] According to the first aspect of the present invention, the first predetermined time and the second predetermined time in the motor control device for an electric reel of the second aspect are the same.

[0009] The motor control device for an electric reel according to the first or second aspect of the present invention controls the drive output of the motor by fixing the duty ratio in the second output mode. In this case, the drive output of the motor is stable.

[0010] The motor control device for an electric reel according to the first or second aspect of the present invention controls the drive output of the motor by changing the duty ratio in the second output mode according to the amount of wound line. In this case, it becomes possible to keep the winding speed constant in the second output mode.

[0011] In the motor control device for an electric reel according to any one of the first to fourth aspects of the present invention, the multiple stages are divided into three regions: a low-speed region, a medium-speed region in which the motor rotates faster than the low-speed region, and a high-speed region in which the motor rotates faster than the medium-speed region, and the second output mode is executed in the low-speed region. In this case, for example, since the second output mode is executed in the low-speed region during a jigging operation, the operability of the jigging operation using the electric reel is improved. Effect of the Invention

[0012] According to the present invention, the operability of the baiting operation using an electric reel is improved. [Brief description of the drawings]

[0013] [Figure 1] 1 is a perspective view of an electric reel in which an embodiment of the present invention is adopted; [Diagram 2] FIG. 2 is a block diagram showing the configuration of a control system of the electric reel. [Diagram 3] 5 is a flowchart showing an example of the flow of a motor control process of a motor control unit. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An electric reel 100 embodying the present invention is an electric reel that is motor-driven by power supplied from an external power source, as shown in FIG.

[0015] The electric reel 100 includes a reel body 1, a spool 2, a motor 3, a handle 4, a counter case 5, a first pressing portion 11, a second pressing portion 12, and a motor control portion 17. The first pressing portion 11 and the second pressing portion 12 are an example of an operation portion. The first pressing portion 11, the second pressing portion 12, and the motor control portion 17 form a part of a motor control device.

[0016] The reel body 1 has a frame 6, a first side cover 7 covering one side of the frame 6, a second side cover 8 covering the other side of the frame 6, and a front cover (not shown) covering the front of the frame 6. Inside the reel body 1, there are arranged a level wind mechanism (not shown) that operates in conjunction with the spool 2, and a well-known rotation transmission mechanism (not shown) that transmits the rotation of the motor 3 and handle 4 to the spool 2.

[0017] The spool 2 is disposed inside the reel body 1. The spool 2 is rotatably attached to the reel body 1 between a first side cover 7 and a second side cover 8.

[0018] The motor 3 is disposed inside the reel body 1. The motor 3 is PWM controlled by the motor control unit 17, and drives the spool 2 to rotate in the line winding direction in response to the pressing operation of the first pressing portion 11 and the second pressing portion 12.

[0019] The handle 4 is rotatably supported by the first side cover 7. Rotation of the handle 4 in the line winding direction is transmitted to the spool 2 via a drag mechanism (not shown) and a rotation transmission mechanism that transmits the rotation of the motor 3 to the spool 2.

[0020] The counter case 5 is disposed on the upper part of the reel body 1. The counter case 5 is fixed to a frame 6. The counter case 5 is provided with a display unit 10 having a liquid crystal display, a first pressing unit 11, a second pressing unit 12, and first to third operating units 13 to 15.

[0021] The first to third operation units 13-15 are mainly used when making various settings of the electric reel 100. The first to third operation units 13-15 are operated by pressing them. The first to third operation units 13-15 may be touch panels provided on the display unit 10. A control unit 16 (see FIG. 2) that performs various controls is housed inside the counter case 5.

[0022] The first pressing portion 11 and the second pressing portion 12 are provided on the reel body 1 to be operated by pressing. The first pressing portion 11 and the second pressing portion 12 are seesaw-type pressure-sensitive switches. The first pressing portion 11 has a pressure sensor 11a. The pressure sensor 11a outputs a detection value corresponding to the magnitude of the pressing force applied to press the first pressing portion 11 to the motor control unit 17 as an electric signal. The second pressing portion 12 has a pressure sensor 12a. The pressure sensor 12a outputs a detection value corresponding to the magnitude of the pressing force applied to press the second pressing portion 12 to the motor control unit 17 as an electric signal.

[0023] As shown in Fig. 2, the control unit 16 has, as its functional components, a motor control unit 17 for controlling the motor 3, a line length measuring unit 18, a speed detection unit 19, and a display control unit 20 for controlling the display unit 10. The motor control unit 17 controls the drive output of the motor 3 (hereinafter referred to as motor output) in response to a pressing operation on the first pressing unit 11 or a pressing operation on the second pressing unit 12 via a motor driving circuit 21 that PWM drives the motor 3. The motor driving circuit 21 has a current detection unit 21a that detects a current flowing through the motor 3. The current detection unit 66a is an example of a torque detection unit that detects the winding torque of the motor 3. The speed detection unit 19 and the current detection unit 66a constitute a part of a motor control device.

[0024] The control unit 16 is connected to the first pressing unit 11, the second pressing unit 12, and the first to third operation units 13 to 15. The control unit 16 is also connected to the display unit 10, a spool sensor 22 for detecting the rotation speed and rotation direction of the spool 2, and a memory unit 23. The memory unit 23 is, for example, a non-volatile memory, and stores various setting information for the electric reel 100, such as line winding learning result data, data used when calculating line length, shelf position information, and ship side stop position information.

[0025] The line length measuring unit 18 measures the length of the fishing line reeled out from the spool 2 in a conventional manner. The line length measuring unit 18 measures the line length based on data relating to the number of rotations of the spool 2. The speed detecting unit 19 detects the rotation speed of the spool 2 using a spool sensor 22.

[0026] The motor control unit 17 controls the motor output in a plurality of steps in response to the pressing operation on the first pressing unit 11 and the second pressing unit 12. The motor control unit 17 controls the motor output in steps from a stopped state to a maximum output. The motor control unit 17 increases the motor output (e.g., the rotation speed of the motor 3) in response to the pressing force only while the first pressing unit 11 is pressed. The motor control unit 17 decreases the motor output (e.g., the rotation speed of the motor 3) in response to the pressing force only while the second pressing unit 12 is pressed. In addition, the motor output is maintained at the time when the pressing operation on the first pressing unit 11 or the second pressing unit 12 is stopped. The motor control unit 17 controls the motor 3 by a PWM method, and the maximum output is a duty ratio of 100%. The motor output is, for example, the rotation speed of the motor 3 and / or the winding torque of the motor 3.

[0027] In this embodiment, the motor output is adjusted in stages from 0 to Nmax (Nmax+1 stages). Stage 0 is a state in which the motor 3 is stopped, and stage Nmax is a state in which the motor 3 is driven at maximum output. The motor output is adjusted, for example, in 31 stages. A set speed and a set torque are set for each stage, and data relating to the set speed and the set torque are stored in the storage unit 23. In this embodiment, the set speed corresponding to each stage corresponds to the upper limit speed corresponding to each stage, and the set torque corresponding to each stage corresponds to the upper limit torque opposite to each stage.

[0028] The motor control unit 17 includes a first output mode and a second output mode. In the first output mode, when a first time during which the rotation speed of the spool 2 exceeds a first set speed corresponding to a first predetermined stage among a plurality of stages is equal to or longer than a first predetermined time based on the detection result of the speed detection unit 19, the motor output is controlled so that the rotation speed of the spool 2 becomes equal to or lower than a first set speed. In the first output mode, when a second time during which the winding torque of the motor 3 exceeds a first set torque corresponding to a first predetermined stage is equal to or longer than a second predetermined time based on the detection result of the current detection unit 66a, the motor output is limited so that the winding torque of the motor 3 becomes equal to or lower than a first set torque.

[0029] The second output mode maintains the motor output when the first time during which the first set speed corresponding to the first predetermined step is exceeded and the second time during which the first set torque corresponding to the first predetermined step is exceeded are less than the first predetermined time and the second predetermined time, respectively.

[0030] The multiple stages are divided into three regions: a low-speed region, a medium-speed region where the rotation speed of the motor 3 is faster than that of the low-speed region, and a high-speed region where the rotation speed of the motor 3 is faster than that of the medium-speed region, and the first output mode and the second output mode are executed in the low-speed region. For example, the low-speed region is a region from 0 to 9 stages, the medium-speed region is a region from 10 to 20 stages, and the high-speed region is a region from 21 to 31 stages. In other words, the first output mode and the second output mode are executed in a region where the motor output stages are from 0 to 9 stages, and are not executed in the medium and high-speed regions. Note that the motor output stages corresponding to each speed region may be changed.

[0031] For example, in the medium and high speed ranges, the rotation speed or winding torque of the spool 2 driven by the motor 3 may be feedback-controlled to maintain a set speed or set torque corresponding to a predetermined stage set in response to the operation of the first pressing unit 11 and the second pressing unit 12, or the line winding diameter of the spool 2 may be calculated to maintain a predetermined tension, as in the conventional case. For example, in the medium and high speed ranges, when the rotation speed of the spool 2 drops due to a load, feedback control may be performed to maintain a predetermined rotation speed. The first and second output modes may also be executed in the medium speed range, or in the medium and high speed ranges.

[0032] Next, a part of the flow of the motor control process performed by the motor control unit 17 of the control unit 16 when the power supply of the electric reel 100 is in the ON state will be described with reference to the flowchart shown in FIG.

[0033] In step S11, the motor control unit 17 reads the current motor output stage N.

[0034] In step S12, the motor control unit 17 determines whether or not the current motor output stage N is equal to or lower than stage 9 (stage 9). That is, in step S12, the motor control unit 17 determines whether or not the current motor output stage N is in the low speed range.

[0035] When the motor control unit 17 determines that the current motor output stage N is 9 or less, it executes the process of step S13.

[0036] In step S13, the motor control unit 17 determines whether or not a first time T11, during which the current rotation speed RS11 of the spool 2 exceeds a first set speed RS01 corresponding to the current motor output stage N, is equal to or longer than a first predetermined time T01, based on the detection result of the speed detection unit 19. When the motor control unit 17 determines that the first time T11 is equal to or longer than the first predetermined time T01, it executes the process of step S14. The first time T11 is measured, for example, via a timer (not shown). The first predetermined time T01 is, for example, 1 second.

[0037] In step S14, the motor control unit 17 determines whether or not a second time T21, at which the current winding torque TR11 of the motor 3 exceeds a first set torque TR01 corresponding to the current motor output stage N, is equal to or longer than a second predetermined time T02, based on the detection result of the current detection unit 21a. If the motor control unit 17 determines that the second time T21 is equal to or longer than the second predetermined time T02, it executes the process of step S15. The second time T21 is measured, for example, via a timer. The second predetermined time T02 is, for example, 1 second, and is the same as the first predetermined time T01.

[0038] In step S15, the motor control unit 17 limits the motor output so that the rotation speed RS11 of the spool 2 becomes equal to or less than the first set speed RS01, and so that the winding torque TR11 of the motor 3 becomes equal to or less than the first set torque TR01.

[0039] When the motor control unit 17 determines in step S14 that the second time T21 is shorter than the second predetermined time T02, the motor control unit 17 executes the process of step S16. In step S16, the motor control unit 17 limits the motor output so that the rotation speed RS11 of the spool 2 becomes equal to or lower than the first set speed RS01.

[0040] When the motor control unit 17 determines in step S13 that the first time T11 is shorter than the first predetermined time T01, the motor control unit 17 executes the process of step S17. Step S17 is the same process as step S14, and therefore the description thereof will be omitted.

[0041] When the motor control unit 17 determines in step S17 that the second time T21 is equal to or greater than the second predetermined time T02, the motor control unit 17 executes the process of step S18. In step S18, the motor control unit 17 limits the motor output so that the winding torque TR11 of the motor 3 is equal to or less than the first set torque TR01. That is, in steps S15, S16, and S18, the motor output is controlled in the first output mode.

[0042] When the motor control unit 17 determines in step S17 that the second time T21 is less than the second predetermined time T02, it executes the process of step S19. In step S19, the motor control unit 17 maintains the motor output. In step S19, the motor output is controlled in the second output mode. In step S19, the motor control unit 17 controls the motor output by fixing the duty ratio. For example, the motor control unit 17 controls the motor output by fixing the duty ratio to a value corresponding to the first set speed RS01. This maintains the drive of the motor 3.

[0043] In step S19, the motor control unit 17 may change the duty ratio according to the amount of thread wound to control the motor output, thereby maintaining the drive of the motor 3. In detail, the duty ratio according to the amount of thread wound may be preset using the diameter of the spool 2 used for thread winding learning, and the duty ratio may be changed according to the amount of thread wound based on the measurement result of the thread length measurement unit 18.

[0044] In the motor control device of this electric reel 100, in the second output mode of the motor control unit 17, when the rotation speed of the spool 2 and the winding torque of the motor 3 exceed a predetermined value for, for example, only a short time, it is possible to maintain the drive output of the motor 3. Therefore, even if at least one of the rotation speed of the spool 2 and the motor 3 exceeds a predetermined value for only a short time due to a jerking motion to lift the rod and additional winding with the handle 4, it is possible to prevent the drive of the motor 3 from stopping. This improves the operability of the jigging motion using the electric reel 100.

[0045] <Other embodiments> Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0046] In the above embodiment, the first pressing portion 11 and the second pressing portion 12 are described as an example of the operation portion, but the operation portion may be configured by a lever-type, a sliding-type, or a rotating-type member. The first predetermined time may be different from the second predetermined time.

[0047] A program for realizing the motor control processing of the motor control unit 17 described above may be recorded on a computer-readable recording medium, and the motor control processing may be performed by, for example, a CPU (Central Processing Unit) executing the program recorded on the recording medium.
