[Patent Document 1] Japanese Patent Laid-Open No. 10-337138

[Patent Document 2] Japanese Patent Application Laid-Open No. 10-108602

The operating member of Patent Document 1 changes the output of the pressure sensor according to the strength of the pressing force, and changes the winding speed of the roll according to the output. However, in order to maintain the speed, it is necessary to continuously press the operating member. On the other hand, the speed adjustment switch of Patent Document 2 can directly maintain the rotation speed of a motor that is increased or decreased by a switch operation, but because the rotation speed of the motor changes according to the operation time of the switch, it is fast and easy It is difficult to achieve the desired speed.

An object of the present invention is to provide a motor control device for an electric winder with which the motor output can be adjusted quickly and easily.

A motor control device for an electric reel according to one aspect of the present invention is a motor-driven reel that is rotatably mounted on the reel body, and includes a first pressing operation portion and a second pressing operation portion, and motor control. means. The first pressing operation portion and the second pressing operation portion are provided in the main body of the reel and have a pressure sensor that changes the output according to the pressing force. The motor control means includes an output increasing means, an output reducing means, and an output maintaining means, and controls the motor output of the motor in response to the output of the pressure sensor. The output increasing means is to increase the motor output corresponding to the output of the pressure sensor when the first pressing operation portion is pressed. The output reduction means is to reduce the motor output according to the output of the pressure sensor when the second pressing operation portion is pressed. The output maintaining means maintains the motor output when the pressing is stopped by the first pressing operation portion or the second pressing operating portion.

The motor control device of this electric reel is provided with a pressure sensor in each of the two pressing members of the first pressing operation section and the second pressing operation section. And, by changing the output of the pressure sensor generated by the pressing force, the motor output can be increased or decreased according to the pressing force. Further, when the pressing of the first pressing operation portion or the second pressing operation portion is stopped, the motor output when the pressing is stopped is maintained. Therefore, it is not necessary to continuously press the pressing operation portion when maintaining a certain motor output, and the motor output can be adjusted quickly and easily only by changing the pressing force.

Preferably, the motor output is the rotation speed of the motor, and the means for increasing the output and the means for reducing the output are such that the larger the pressing force is, the larger the rotation speed of the motor is increased or decreased. In this case, since the angle of rotation of the motor is greatly increased or decelerated if the angler presses the pressing operation portion strongly, the feeling of the angler and the rotation speed of the motor are integrated, and the adjustment of the motor output becomes easier.

Preferably, the motor output is the torque of the motor, and the means for increasing the output and the means for reducing the output are to increase or decrease the torque of the motor substantially as the pressing force increases. In this case, if the angle of the motor is greatly increased or decreased when the angler presses the pressing operation portion strongly, the feeling of the angler and the torque of the motor are integrated, and the adjustment of the motor output becomes easier.

Preferably, the first pressing operation portion and the second pressing operation portion are provided on an upper surface or a side surface of the reel main body. Accordingly, even when the electric reel is held, the pressing operation portion can be pressed by the fingertips of the gripped hand, thereby improving operability.

According to the present invention, the motor control device of the electric winder can quickly and easily adjust the motor output.

5 is a flowchart showing a flow of processing by a motor control unit according to the second embodiment.

The electric reel mainly includes: a reel body 1 that can be mounted on a fishing rod; a reel 2 that is arranged inside the reel body 1; and a reel 2 that is arranged on the side of the reel body 1. An operating lever 3 for rotation, a star-shaped tractor 4 for traction adjustment, and a meter counter case 5 for displaying water depth, which are arranged on the reel body side of the operating lever 3.

The reel main body 1 includes a frame 6, first and second side covers 7 a and 7 b covering the left and right sides of the frame 6, and a front cover (not shown) that covers the front portion of the frame 6. Further, a uniform winding mechanism (not shown) that operates in conjunction with the reel 2 and an unillustrated transmission of rotation of the operation lever 3 and a motor 8 to be described later to the reel 2 are provided inside the reel body 1. Rotation transmission mechanism, etc.

The reel 2 is rotatably provided between the first side cover 7a and the second side cover 7b on the reel body 1. A motor 8 is provided inside the reel 2 to rotate and drive the reel 2 in the wire take-up direction.

The operation lever 3 is rotatably supported by a lower center portion of the first side (right side) cover 7a. The clutch operating member 9 is swingably disposed above the support portion of the operating lever 3. The clutch operating member 9 is a member for turning ON and OFF a clutch (not shown) provided between the operating lever 3 and the motor 8 and the spool 2.

A display portion 10 including a liquid crystal display is provided on the upper surface portion of the meter counter case 5. On the rear side of the display section 10, as shown in FIGS. 1 and 3, a first pressing operation section 11 and a second pressing operation section 12 are arranged, and they protrude upward from the meter counter case 5. 2 operation switches 13. Here, the first and second pressing operation portions 11 and 12 are arranged so as to be biased from the center in the left-right direction to the side opposite to the operation lever 3. The first pressing operation section 11 and the second pressing operation section 12 are arranged adjacent to each other. The control unit 14 that performs various kinds of control is housed inside the meter counter case 5.

The first and second pressing operation sections 11 and 12 include pressure sensors 11 a and 12 a as shown in FIG. 2. The pressure sensors 11a and 12a are means for outputting electrical signals at a level corresponding to a force (hereinafter referred to as a pressing force) for pressing the first and second pressing operation portions 11, 12 and detect the magnitude of the pressing force. The output value is output as an electric signal to the motor control unit 16 of the control unit 14 described later. The first pressing operation portion 11 increases the output of the motor 8 (hereinafter referred to as a motor output) corresponding to the pressing force only while the first pressing operation portion 11 is pressed (for example, the rotation speed of the motor 8 increases). The second pressing operation portion 12 reduces the motor output corresponding to the pressing force only while the second pressing operation portion 12 is pressed (for example, the rotation speed of the motor 8 decreases).

The motor driving circuit 19 controls driving of the motor 8 in response to the pressing operation of the first and second pressing operation sections 11 and 12.

    <Processing Flow of Motor Control Unit>    

Next, the flow of the motor control processing performed by the motor control unit 16 of the control unit 14 when the power of the electric winder is in the ON state will be described based on the flowchart shown in FIG. 4. The motor output here is, for example, the rotation speed of the motor 8. When a load is applied to decrease the rotation speed of the reel 2, the rotation speed of the reel 2 is controlled by feedback so as to maintain a predetermined rotation speed.

First, in step S1, it is determined whether or not the first pressing operation section 11 is pressed. If it is determined that it has been pressed, the process proceeds to step S2.

In step S2, the motor output (in this case, the rotation speed of the motor 8) is increased by the output corresponding to the electrical signal output from the pressure sensor 11a of the first pressing operation portion 11.

Next, in step S3, it is determined whether or not the pressing of the first pressing operation section 11 is stopped. If it is not stopped, the rotation speed of the motor 8 is increased by the motor output corresponding to the electrical signal output from the pressure sensor 11a until the pressing is stopped. If it is determined that the pressing is stopped, the process proceeds to step S8 to maintain the motor output when the pressing is stopped. That is, here, the rotation speed of the motor 8 when the pressing of the first pressing operation section 11 is stopped is maintained.

If it is determined in step S1 that the first pressing operation portion 11 is not pressed, the process proceeds to step S4. Then, in step S4, it is determined whether or not the second pressing operation section 12 is pressed. If it is determined that it has been pressed, the process proceeds to step S5. If it is not pressed, the motor control processing is not executed.

Next, in step S5, it is determined whether there is a motor output (here, the rotation speed of the motor 8, that is, whether the motor 8 is rotating). If there is no motor output, the motor control processing is not executed. If there is a motor output, the process proceeds to step S6.

In step S6, the motor output (here, the rotation speed of the motor 8) is reduced by the output corresponding to the electric signal output from the pressure sensor 12a of the second pressing member 12.

Next, in step S7, it is determined whether or not the pressing of the second pressing operation section 12 is stopped. If it is not stopped, the rotation speed of the motor 8 is reduced by the motor output corresponding to the electrical signal output from the pressure sensor 12a until the pressing is stopped. If it is determined that the pressing is stopped, the process proceeds to step S8 to maintain the motor output when the pressing is stopped. That is, the rotation speed of the motor 8 when the pressing of the second pressing operation portion 12 is stopped is maintained here.

Here, in step S2, the motor control unit 16 increases the motor output (here, the rotation speed of the motor 8) by the motor output corresponding to the electrical signal output from the pressure sensor 11a of the first pressing operation unit 11 At this time, it is controlled so that the rotation speed of the motor 8 is increased significantly as the pressing force of the first pressing operation portion 11 increases. Then, in step S6, when the motor output (here, the rotation speed of the motor 8) is reduced by the motor output corresponding to the electrical signal output from the pressure sensor 12a of the second pressing operation portion 12, the motor output corresponding to the The pressing force of the pressing operation portion 12 is increased, and the rotation speed of the motor 8 is drastically reduced (for example, the rotation of the motor 8 is stopped momentarily when it is pressed strongly).

Accordingly, when the angler strongly presses the first or second pressing operation portions 11, 12, the rotation speed of the motor 8 is greatly increased or decreased. Therefore, the feeling of the fisherman and the motor output are integrated, and the motor output can be adjusted quickly and easily.

    [Second embodiment]    

Next, the flow of the motor control processing performed by the motor control unit 16 in the electric reel according to the second embodiment of the present invention will be described with reference to the flowchart shown in FIG. 5. The flow of the motor control process of the second embodiment is a further closer control process for the motor control process of the first embodiment. The same processing as in the first embodiment will not be described here. In the second embodiment, the motor output is also, for example, the rotation speed of the motor 8. When a load is applied to reduce the rotation speed of the reel 2, it is feedback-controlled so as to maintain a predetermined rotation speed.

And the motor output is controlled from Nmax + 1 stage from 0 to Nmax. Segment 0 is the state where the motor 8 is stopped, and segment Nmax is the state where the motor 8 is driven by the maximum output. Here, for example, the motor 8 is controlled by the PWM method, and the maximum output is a load operation (power) ratio of 100%.

Furthermore, here, a lower limit value and an upper limit value (for example, a lower limit value of 30 g and an upper limit value of 2 kg) of the pressing force output from the pressure sensors 11a and 12a are set. In addition, the range of the lower limit value and the upper limit value is divided into arbitrary stages (for example, 31 equal divisions), and the number of increase and decrease of the motor output setting stage corresponding to each stage is increased.

First, in step S21, it is determined whether the first pressing operation portion 11 is pressed by a pressing force P1 of 30 g or more. Specifically, by detecting the output from, for example, the pressure sensor 11a of the first pressing operation section 11, it is determined whether the first pressing operation section 11 is pressed by a pressing force P1 of 30 g or more. When only an output with a pressing force P1 of 30 g or less is detected, the output is ignored as a person who has not been pressed in order to avoid misoperation. Here, for example, a resistance film type pressure sensor is used, and a circuit is configured such that an output voltage is proportional to a pressing force.

When it is determined that the pressing force P1 is 30 g or more, the process proceeds to step S22, and it is determined whether the pressing force P1 is 2 Kg or less. If the pressing force is 2Kg or more in step S22, the process proceeds to S31, and the motor output stage N is changed to Nmax. And, in the next step S29, the motor output is maintained by the stage Nmax.

When the motor output at the stage Nmax is maintained, when the first pressing operation portion 11 is pressed by the pressing force P1 of 2 kg or more, the process proceeds to step S31, but the motor output has been maintained at the stage Nmax. Therefore, as a result, the motor output is continuously maintained by the stage Nmax.

If the pressing force P1 is 2 Kg or less in step S22, the process proceeds to step S23, and the current motor output stage N is read in.

Next, in step S24, the stage increase number M set in advance to the output of the pressure sensor 11a is read from the memory, and the process proceeds to step S25.

In step S25, it is determined whether or not the phase increase number M is increased by the current motor output phase N by Nmax or less. If Nmax or less, move to step S26 and set N + M as the new motor output stage. Specifically, for example, when the first pressing operation portion 11 is pressed by a pressing force P1 of 300 g to 400 g in the state of the motor output in the motor output stage 5, a stage in which a range corresponding to the pressing force P1 is set in advance is added. Increase the number by 2 and set the motor output stage to 7. After that, the process proceeds to step S27.

In step S25, when the current motor output stage N is increased by the number of stages M plus Nmax, the process proceeds to step S30 and the motor output stage is set to Nmax-1 in one stage. That is, as long as the pressing force P1 toward the first pressing operation portion 11 does not exceed 2 Kg, the motor output stage does not become Nmax. After that, the process proceeds to step S27.

In step S27, for example, it moves to step S28 after waiting for 0.5 second.

In step S28, it is determined whether the first pressing operation portion 11 is pressed by a pressing force P1 of 30 g or more in the same manner as in step S21. That is, it is determined here whether the first pressing operation section 11 is continuously pressed by a pressing force P1 of 30 g or more. If it is pressed by the pressing force P1 of 30 g or more, it returns to step S22. If it is not pressed by the pressing force P1 of 30 g or more, the process proceeds to step S29, and the motor output is maintained at the motor output stage set in step S26 or step S30.

If it is determined in step S21 that the first pressing operation portion 11 has not been pressed by the pressing force P1 of 30 g or more, the process proceeds to step S32.

In step S32, based on the output from the pressure sensor 12a, it is determined whether the second pressing operation portion 12 is pressed by a pressing force P2 of 30 g or more. When only an output with a pressing force P2 of about 30 g or less is detected, its output is ignored as a person who has not been pressed in order to avoid misoperation.

When it is determined that the pressing force P2 is 30 g or more, the process proceeds to step S33 to determine whether the motor output stage N is 1 or more, that is, whether the motor is driven. If the motor output stage N is 0, since the operation of the second pressing operation section 12 for output reduction is meaningless, the motor control processing is not performed. If the motor output stage N is 1 or more, the process proceeds to step S34.

In step S34, it is determined whether the pressing force P2 is 2 kg or less. When the pressing force P2 is 2 Kg or more, the process proceeds to step S42 and the current motor output stage N is changed to 0. That is, the driving of the motor 8 is stopped.

When the pressing force P2 is 2 Kg or less in step S34, the process proceeds to step S35, and the current motor output stage N is read in.

Next, in step S36, the phase reduction number L set in advance to the output of the pressure sensor 12a is read from the memory, and the process proceeds to step S37.

In step S37, it is determined whether or not the person who has decreased the number L of steps by the number L from the current motor output stage N is 1 or more. If it is more than 1, move to step S38, set N-L as the new motor output stage, and move to step S39. If N-L is 1 or less, go to step S41 and set the motor output stage to 1 and go to step S39.

In step S39, the process proceeds to step S40, for example, after 0.5 seconds of standby.

In step S40, it is determined whether the second pressing operation portion 12 is pressed by a pressing force P2 of 30 g or more in the same manner as step S32. That is, it is determined here whether the second pressing operation portion 12 is continuously pressed by a pressing force P2 of 30 g or more. If it is pressed by the pressing force P2 of 30 g or more, the process returns to step S34. If it is not pressed by the pressing force P2 of 30 g or more, the process proceeds to S29, and the motor output is maintained at the motor output stage set in step S38 or step S41.

    <Other Examples>    

Although an embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various changes can be made without departing from the scope of the invention.

    <Other Examples>    

(a) The pressure sensors 11a and 12a are not a single component such as a pressure sensing element, but may be outputted in response to a slight displacement amount of a member pressed by a spring with a large spring constant.

(b) In the foregoing embodiment, although the rotation speed of the reel 2 is detected as the motor output for feedback control, the current value supplied to the motor 8 may be controlled to make the winding torque a predetermined value. At this time, for example, the torque of the motor 8 is greatly increased or decreased when the first or second pressing operation portions 11 and 12 are strongly pressed by the angler, so that the angler feels and the motor. The output is integrated and the motor output can be adjusted quickly and easily. Alternatively, control may be performed such that the tension of the wire winding diameter of the spool 2 is calculated to a predetermined value.

(c) In the foregoing embodiment, the control method when the motor 8 is rotated in response to the electrical signals output from the pressure sensors 11a and 12a is controlled by a predetermined reel rotation speed and a predetermined torque value. You can choose any two of them.

(d) The first and second pressing operation portions 11 and 12 of the foregoing embodiment may protrude from the meter counter case 5.

(e) The first and second pressing operation portions 11 and 12 of the foregoing embodiment may be arranged on the upper surface or side surface of the reel main body 1. Further, the surfaces on which the first and second pressing operation sections 11 and 12 are arranged may be inclined on one side with respect to the other, or may be arranged on a curved surface. These are preferably the front-rear arrangement, and may be arranged in the left-right and oblique directions according to the swing of the thumb.

(f) The first and second pressing operation sections 11 and 12 that can operate the foregoing embodiment may be configured using a single swing operation tool.

(g) The motor control unit 16 may control the motor output so as to stop the motor output when the first and second pressing operation units are simultaneously pressed while maintaining the motor output in step S8 in FIG. 4. This makes it possible to stop the motor output more quickly.

(h) In the foregoing embodiment, when the range of the lower limit value and the upper limit value of the pressing force output from the pressure sensors 11a and 12a is divided into arbitrary stages, the range may be divided unevenly. . For example, if the pressing force is small, that is, the range of the pressing force corresponding to the stage where the number of increase and decrease of the motor output stage is low may be larger than the range of the higher stage. This makes it easy to perform fine adjustments such as slightly increasing or decreasing the rotational speed.

(i) In the foregoing embodiment, although the lower limit value and the upper limit value of the pressing force detected by the pressure sensors 11a and 12a (for example, the lower limit value is 30 g and the upper limit value is 2 kg) are set in advance, However, the lower limit value and the upper limit value, that is, the threshold value of the pressing force, can be arbitrarily set by the fisherman. At this time, if the first and second pressing operation portions 11 and 12 are operated with a predetermined pressing force or more while the motor 8 is stopped, the pressing force setting mode for setting the threshold value of the pressing force may be used.

(j) In the foregoing embodiment, the presence or absence of the operation of the second pressing operation section 12 is determined after the presence or absence of the operation of the first pressing operation section 11. However, both of the first and second pressing operation sections 11 and 12 are determined. The output of the pressure sensors 11a and 12a can be compared, and the larger output, that is, the larger pressing force, can be determined as an effective pressing operation.
