[0001]

TECHNICAL FIELD The present invention relates to a motor control device,
In particular, the present invention relates to a motor control device for an electric reel for controlling a spool rotation motor mounted on a reel body.

[0002]

2. Description of the Related Art In general, an electric reel that rotates a spool at the time of winding by a motor is often used, for example, when catching fish migrating at a depth of 100 m or more from a boat. This type of electric reel includes a reel body, a spool mounted on the reel body, a handle for rotating the spool, and a motor for rotating the spool in a winding direction. An operation panel provided with a display for displaying water depth and switches for performing various inputs is mounted on the upper surface of the reel body.

In such an electric reel, the rotation speed of a motor is changed by operating a swingable operation member provided on a side portion of the reel body. Thereby, the winding speed of the spool is changed. In such an operation member, the motor is changed from the off state to the maximum rotation state by the swing of the operation member. When the operating member swings to a certain swing position, the operating member is held at the swing position, and the rotation of the motor is maintained at a speed corresponding to the swing position.

[0004]

In the conventional operating member, the swing position of the operating member corresponds to the rotation speed of the motor. Therefore, in order to realize a desired rotation speed, the operating member must be moved to a predetermined position. It is necessary to swing to the swing position. For this reason, for example, a pointer such as an arrow provided on the operation member must be matched with a scale indicating a speed position corresponding to a predetermined swing position provided on the reel body side, so that operation of the operation member is troublesome. It is.

Further, in order to change the operating member from the ON state to the OFF state, it is necessary to swing the operating member from a certain speed position to the OFF position, and the motor cannot be turned off instantaneously. Therefore, it is difficult to operate the operation member when turning off the motor.

An object of the present invention is to improve the operability of an operation member in a motor control device for an electric reel.

[0007]

SUMMARY OF THE INVENTION A motor control device according to a first aspect of the present invention is a motor control device for an electric reel for controlling a motor for rotating a spool mounted on a reel body, and is provided in two directions from a neutral position. An operating member provided on the reel body so as to be swingable and movable in a direction different from the swing direction at the neutral position, first rotation control means for turning on and off a motor by a moving operation of the operating member, A second rotation control means for increasing the number of rotations of the motor when swinging in one direction from the neutral position and decreasing the number of rotations of the motor when swinging the operating member in the other direction from the neutral position; Biasing means for biasing the position.

In this motor control device, the operating member for changing the speed of the motor is always at the neutral position even if it is located at the speed increasing position oscillated in one direction and the deceleration position oscillating in the other direction. Being energized. For this reason, when it is desired to increase the speed of the motor, the speed can be determined based on, for example, the number of times the motor is positioned at the speed increasing position, the time for maintaining the speed increasing position, and the like. Since the operating member always returns to the neutral position, the speed can be changed only by positioning the operating member at the speed increasing position or the decelerating position based on the neutral position. Therefore, it is not necessary to adjust the operation member to a predetermined swing position corresponding to the rotation speed, and the operability of the operation member can be improved.

To turn the motor on and off, a moving operation is performed at a neutral position. As described above, the on / off operation and the speed change can be performed by the movement operation and the swing operation of one operation member, respectively, so that the operability of the operation member can be further improved.

A motor control device according to a second aspect of the present invention is the motor control device according to the first aspect, wherein the first rotation control means stops the rotation of the motor by a moving operation of the operation member when the motor is on, and stops when the motor is off. The motor is rotated by the operation of moving the operation member. In this case, it is a toggle switch that switches between an on state and an off state each time the operation member is moved. Therefore, for example, when the operating member is turned on by the swinging operation, the motor can be instantaneously turned off by performing the moving operation with the hand.

A motor control device according to a third aspect of the present invention is the motor control device according to the first aspect, wherein the first rotation control means rotates the motor while the operation member is being moved. In this case, it is possible to perform a jogging winding in which the operating member is moved while the operation member is being moved for a predetermined time.

A motor control device according to a fourth aspect of the present invention is the motor control device according to the third aspect, wherein the first rotation control means continuously rotates the motor when the operating member is moved twice within a predetermined period. In this case, a jogging winding in which the operating member is wound while the operating member is being moved, and the operating member is
By performing the turning operation, both continuous winding and continuous winding can be performed.

A motor control device according to a fifth aspect of the present invention is the motor control device according to any one of the first to fourth aspects, wherein the second rotation control means maintains the rotation state of the motor when the operating member is at the neutral position. In this case, the off state can be maintained when the motor is off, and the on state at that speed can be maintained when the motor is on.

A switch operation unit 6 is provided around the display unit 5.

The display unit 5 has a four-digit seven-segment depth display area 5a arranged in the center, a three-digit bottom depth display area 5b disposed below the four-segment depth display area 5b, and a right-hand part of the depth display area 5a in FIG. And a rotation state display area 5c arranged at In addition, the display unit 5 displays “from the bottom”, “learning”,
Eight characters of “designation”, “lower volume”, “correction”, “input”, “thread feed stop”, and “0 set” can be displayed.

As shown in FIG. 3, the switch operation unit 6
A bottom memo switch SM and a mode switch MD which are arranged vertically on the left side of the display unit 5; Example).

The bottom memo switch SM is a switch that is pressed when the device reaches the bottom, and the water depth at that time is set as the bottom. The mode switch MD is a switch for setting five types of pincushion modes. For example, pressing the switch once sets the learning mode, and pressing it twice consecutively sets the designated mode, and pressing it three times consecutively sets the lower winding. The mode is set to the correction mode when pressed continuously four times, and the pincushion mode is set to the input mode when pressed continuously five times.

As shown in FIGS. 1 to 3, the joystick JS is used to turn on and off the motor 12 by moving the joystick JS in the pressing direction (downward in FIG. 2) at the neutral position N (see FIG. 2). This is a switch, and can perform a jogging hoist that rotates the motor 12 while the joystick JS is being turned on.
Further, by continuously moving the joystick JS twice, it is possible to continuously wind the motor 12 continuously.

The rotation speed of the motor 12 can be arbitrarily changed by swinging the joystick JS in the front-rear direction (the left-right direction in FIG. 2). Joystick JS
Is connected to the reel body 1 by a spring member (an example of an urging means) not shown, and is urged to always come to the neutral position N. When the joystick JS swings from the neutral position N to the forward speed increasing position A, the speed increases (to the right in the direction of the solid line arrow in FIG. 2), and when the joystick JS swings from the neutral position N to the backward speed reducing position B, the speed decreases (FIG. 2). Solid arrow left direction). When the joystick JS is released at the acceleration position A or the deceleration position B, the joystick JS is actuated by the biasing force of the spring member.
Is returned to the neutral position N (the direction of the dotted arrow in FIG. 2).

At the upper part of the counter case 4, a display unit 5 is provided.
And a reel control unit 30 for performing display control and motor control
(See FIG. 4). A PWM drive circuit 31 (see FIG. 4) for driving the motor 12 by PWM is arranged in a lower portion of the counter case 4. Further, a buzzer 40 (see FIG. 4) and a spool sensor 41 (see FIG. 4) are arranged in a lower portion inside the counter case 4.

The reel control unit 30 includes a microcomputer including a CPU, a RAM, a ROM, an I / O interface, and the like arranged in the counter case 4.
The reel control unit 30 controls the display unit 5 according to the control program.
And various control operations such as display control and motor drive control. As shown in FIG. 4, the reel control unit 30 includes various switches of the switch operation unit 6, a spool sensor 41 for detecting the rotation direction and the number of rotations (rotational position data) of the spool 10, and a spool counter 42. It is connected. Further, the buzzer 40 and P
The WM drive circuit 31, the display unit 5, the storage unit 43, and other input / output units are connected.

The PWM drive circuit 31 includes an FET as a drive element for driving the motor 12. PW
The M drive circuit 31 drives the motor 12 at a variable speed by controlling the duty ratio of the motor drive current by the reel control unit 30.

The spool sensor 41 is composed of two reed switches arranged side by side. The reed switch detects two magnets mounted on the magnet wheel. The number of rotations of the reel can be detected by counting the detection pulses by the spool counter 42. Further, the rotation direction of the spool 10 can be detected based on which reed switch has issued the detection pulse first.

The spool counter 42 is a counter for counting the number of times the spool sensor 41 is turned on and off. Rotational position data relating to the number of rotations of the spool is obtained from the counted value. The count value of the spool counter 42 decreases when the spool 10 rotates forward (rotation in the line feeding direction), and increases when the spool 10 rotates reversely.

The storage unit 43 is composed of a nonvolatile memory such as an EEPROM, for example, and stores learning result data and various data used when calculating the yarn length. Next, a specific control process performed by the reel control unit 30 will be described.
The description will be given according to the control flowchart of FIG.

When the electric reel is connected to the external power supply PS via the power cord 18, initialization is performed in step S1 of FIG. In this initial setting, spool counter 4
The count value of No. 2 is reset, various variables and flags are reset, and the water depth display mode is set to the mode from above.

Next, in step S2, display processing is performed. In the display processing, various kinds of display processing such as water depth display are performed. Here, in the mode from the top, the water depth reference water depth is displayed in the water depth display area 5a. When the bottom position is set by the bottom memo switch SM, the bottom position is displayed in the bottom depth display area 5b.

In step S3, it is determined whether or not any switch of the switch operation section 6 has been pressed. If a switch input has been made, steps S3 to S
The process proceeds to 6 to execute a switch input process. If the switch input has not been made, the process proceeds to step S4.

In step S4, it is determined whether or not the spool 10 is rotating. This judgment is made by the spool sensor 4
Judgment is made based on the output of 1. 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.

In step S5, it is determined whether another command or input has been made. If another command or input has been made, the process shifts from step S5 to step S8 to execute other processing.

In the switch input processing of step S6, FIG.
In step S11, it is determined whether the winding mode has been set. This determination is made based on whether or not the mode switch MD has been pressed. When the mode switch MD is pressed, the process moves from step S11 to step S15. In step S15, a bobbin mode process is executed.

In step S12, the joystick J
It is determined whether S has been moved. If the joystick JS is moved, the process proceeds to step S16 to perform a motor control process. In step S13, it is determined whether or not the joystick JS is swinging. If "YES" here, the process proceeds to a step S17 to perform a speed control process. In step S14, it is determined whether or not another switch has been operated. The operation of other switches includes the operation of the bottom memo switch SM and the like. If another switch input is made, step S1
The process proceeds from S4 to step S18, and another switch input processing corresponding to the operated switch input such as setting to the bottom shelf value of the current water depth is performed.

In the motor control process of step S16 in FIG. 6, as shown in FIG. 7, the process starts from a state in which the joystick JS is turned on by the moving operation. First, in step S21, it is determined whether or not the joystick JS has been turned on twice within a predetermined time. If "NO" here, that is, if the joystick JS is kept on, the process proceeds to step S22, and it is determined whether the motor 12 is on. If the motor 12 is off, step S2
Then, the process proceeds to step S3, where the motor 12 is rotated, and the process proceeds to step S24. If "YES" is determined in the step S22, that is, if the motor 12 is already on, the process proceeds to a step S24. In step S24, it is determined whether or not the joystick JS is off. When the joystick JS is turned off, the process proceeds to step S25, and the rotation of the motor 12 is stopped. In steps S21 to S25, it is possible to perform the jogging winding for rotating the motor 12 while the joystick JS is being pressed.

On the other hand, if "YES" is determined in the step S21, the process shifts to a step S26 to determine whether or not the motor 12 is rotating. If the motor 12 is rotating, the rotation is stopped in step S28. If the motor 12 is not rotating, the rotation is started in step S27. Here, when the motor 12 is not rotating, the joystick JS is turned on twice so that the motor 12 is turned off.
Can be performed.

In the speed control process of step S17 in FIG. 6, as shown in FIG. 8, it is determined in step S31 whether or not the joystick JS has been swung to the speed increasing position A. When the joystick JS is swung to the acceleration position A, the process proceeds from step S31 to step S33.
In step S33, the rotation of the motor 12 is increased by gradually increasing the duty ratio. In step S31, "N
When it is determined as “O”, the process proceeds to step S32. In step S32, the joystick JS is moved to the deceleration position B
It is determined whether or not it has been rocked. When the joystick JS is swung to the deceleration position B, the process moves from step S32 to step S34. In Step S34, the rotation of the motor 12 is reduced by gradually reducing the duty ratio. Here, if the joystick JS continues to swing to the acceleration position A or the deceleration position B, step S33 or step S34 is repeated, and as a result, the rotation of the motor 12 is increased or decreased according to the swing time of the joystick JS. ing.

In this electric reel, the joystick J
S is swingable in the front-rear direction from the neutral position N so that the neutral position N
Are provided movably. Here, the rotation speed of the motor 12 is changed by swinging the joystick JS back and forth, and the motor 12 is turned on and off by a movement operation at the neutral position N of the joystick JS. Therefore, various operations can be performed with one joystick JS, so that the operability of the operation member can be improved.
