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 roll-up speed of the reel in accordance with the output. However, the pressing force of humans has a personal difference. In addition, there is a possibility that the pressing force becomes weak in a cold environment, and the pressing force is also easily controlled by the environment in which the electric reel is operated. If the pressing force is insufficient, it is difficult to adjust the motor output quickly and easily.

The object of the present invention is to reduce the variation of the motor output by the operating environment and the pressing condition for the electric winder, and 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 rotatably mounted on a reel body, and includes a pressing operation portion, a motor control means, and an output adjustment means. The pressing operation unit is a pressure sensor having a change in output in response to a pressing force, and is provided in the reel body. The motor control means controls the motor output according to the output of the pressure sensor. The output adjustment means is to arbitrarily set the threshold value of the maximum pressing force in the pressure sensor.

The motor control device of this electric winder can arbitrarily set the threshold value of the maximum value of the pressing force in the pressure sensor. because Therefore, even if the motor output changes in response to the pressing force, variations in the motor output due to insufficient and excessive pressing force are not easily generated, and the motor output can be adjusted quickly and easily.

Preferably, the output adjustment means sets a threshold value for the maximum value of the pressing force based on an average value of the pressing force when the pressing operation portion is pressed a plurality of times. In this case, even if there is some variation in the pressing force, because the threshold value of the maximum value of the pressing force is set according to the average value, the lack and excess of the pressing force are less likely to occur.

Preferably, the output adjustment means sets a threshold value for the maximum value of the pressing force in accordance with a predetermined range of the maximum pressing force when the pressing operation portion is pressed.

Preferably, the output adjustment means is to set a threshold value of the maximum value of the pressing force from a plurality of preset pressing force values.

Preferably, the motor control means is to increase the motor output as the pressing force becomes larger. In this case, if the angler presses the pressing operation part strongly, the motor output will increase, and because the angler's feeling and the motor output are integrated, adjustment of the motor output becomes easier.

Preferably, the motor control device further includes an output adjustment member provided on the reel body and adjusting the rotation of the motor in a stepwise manner from a stopped state. The motor control means controls the motor output to an output set by the operation of the output adjustment member, and controls the output of the pressure sensor when the motor is not rotated by the operation of the output adjustment member.

Preferably, the motor control device further includes: An output adjusting member for adjusting the rotation of the motor in a stepwise manner from a stopped state to the reel body. The motor control means controls the motor output to an output set by the operation of the output adjustment member, and when the motor is rotated by the operation of the output adjustment member, the output corresponding to the pressure sensor is reduced.

Preferably, the output adjustment member is a swing operation lever, and the motor output is adjusted in stages according to its swing position.

Preferably, the output adjustment member is rotatably provided on the reel body, and the motor output is adjusted in stages according to the rotation position.

Preferably, the pressing operation portion is integrally provided on the output adjusting member, and changes the output of the pressure sensor in response to the pressing force in the radial direction of the output adjusting member.

According to the present invention, since the threshold value of the maximum value of the pressing force in the pressure sensor can be adjusted, variations in motor output caused by insufficient and excessive pressing force are not easily generated, and the The motor output produced by pressing is quickly and easily adjusted.

The clutch operating member 10 is a member for turning ON and OFF a clutch (not shown) provided between the operating lever 3 and the motor 8 and the reel 2.

The meter counter case 5 is an upper portion disposed on the front side of the reel main body 1 and is fixed to the first side plate 6a and the second side plate 6b. A display section 11 including a liquid crystal display is provided on the upper surface of the meter counter case 5. On the rear side of the display section 11, as shown in FIGS. 1 and 3, a pressing operation section 12 and two operation switches 13 protruding upward from the meter counter case 5 are arranged. Inside the meter counter case 5 is housed a control unit 14 that performs various controls.

As shown in FIG. 2, the pressing operation section 12 includes a pressure sensor 15. The pressure sensor 15 is a member that outputs an electrical signal at a level corresponding to the pressing force of the pressing operation portion 12 (hereinafter referred to as a pressing force), and the detected value corresponding to the magnitude of the pressing force is used as a control unit for the electric signal to be described later The motor control unit 16 of 14 outputs. When the motor 8 is not driven by the operation of the output adjustment operation lever 9, the motor 8 is driven at, for example, a rotation speed in accordance with the output of the pressing force only while the pressing operation portion 12 is being pressed.

The motor driving circuit 19 controls the driving of the motor 8 in response to the operation of the output adjustment operation lever 9 and the pressing operation of the pressing operation portion 12.

<Processing Flow of Motor Control Unit>

Next, the flow of the motor control process performed by the motor control unit 16 of the control unit 14 when the power of the electric reel is in the ON state will be described with reference to the flowchart shown in FIG. 4.

First, in step S1, it is determined whether the output adjustment operation lever 9 is located at a stop position (a position where the rotation of the motor 8 generated by the output adjustment operation lever 9 will not occur). If the output adjustment operation lever 9 is not in the stop position, the output adjustment operation lever 9 is given priority over the pressing operation portion 12, so it moves to step S4, and the output corresponding to the position of the output adjustment operation lever 9 (for example, becomes a regulation here Of the reel rotation speed) causes the motor 8 to rotate. In addition, feedback control is performed so that a predetermined rotation speed is maintained when a load is applied to decrease the reel rotation speed. If it is determined that it is at the stop position, the process proceeds to step S2.

In step S2, it is determined whether the slave pressure sensor 15 has an output of an electrical signal. If there is an electric signal output, the process proceeds to step S3, and the motor 8 is rotated in response to the output of the electric signal output from the pressure sensor 15 (for example, a method of setting a predetermined drum rotation speed here). turn. If no electric signal is output from the pressure sensor 15, the motor control processing will not be performed.

In step S3, when the motor 8 is rotated by an output corresponding to an electric signal output from the pressure sensor 15, for example, the motor 8 is controlled to have a predetermined reel rotation speed, and the motor is caused to increase as the pressing force increases. The rotation speed of 8 is controlled in a rapid manner. As a result, when the angler presses the pressing operation portion 12 strongly, the rotation speed of the motor 8 becomes fast. Since the angler's feeling and the motor output are integrated, the adjustment of the output of the motor 8 becomes easy.

<For output adjustment means>

Next, a flow of processing when the threshold value of the maximum value of the pressing force in the pressure sensor 15 is arbitrarily set will be described with reference to a flowchart shown in FIG. 5. This processing is performed by the motor control unit 16.

In step S11, it is determined whether the operation switch 13 is continuously pressed for 3 seconds or more. If it is determined that the operation switch 13 is pressed for 3 seconds or more, the process proceeds to step S12.

In step S12, it is determined whether the motor 8 is rotating. That is, it waits for the rotation of the motor 8 to stop and executes the subsequent processing.

When the rotation of the motor 8 is stopped, the process moves from step S12 to step S13. In step S13, it switches to the setting mode for setting the threshold value of the maximum value of a pressing force.

After switching to the setting mode, if the pressing operation part 12 is pressed, in step S14, the maximum pressing force is set according to the pressing force at this time. The threshold of the value. At this time, for example, the pressing force is measured a plurality of times, and the threshold value of the maximum value of the pressing force is set according to the average value of the pressing force. Even if the pressing force has some variations, the pressing force is based on the average value. The threshold value of the maximum value is set, so the shortage and excess of the pressing force are less likely to occur.

<Second Embodiment>

The flow of processing of the output adjustment means in the second embodiment of the present invention will be described with reference to FIG. 6. In addition, since the reel main body 1 in the second embodiment has the same configuration as that in the first embodiment, description thereof will be omitted. The motor control processing performed by the motor control unit 16 is the same as that of the first embodiment, and therefore description thereof will be omitted.

In the second embodiment, this processing is also performed by the motor control unit 16. In addition, since the processing other than step S24 is the same as that in FIG. 5, only the processing for setting the threshold value of the maximum value of the pressing force performed in step S24 will be described here. That is, in step S24, a threshold value for the maximum value of the pressing force is set in accordance with a predetermined range of the maximum pressing force (for example, 80% of the maximum pressing force). The predetermined range of the maximum pressing force is not limited to this.

<Third Embodiment>

The flow of processing of the output adjustment means in the third embodiment of the present invention will be described with reference to FIG. 7. In addition, since the reel main body 1 in the third embodiment has the same configuration as that in the first embodiment, description thereof will be omitted. And The motor control processing performed by the motor control unit 16 is the same as that of the first embodiment, and therefore description thereof is omitted.

In the third embodiment, this processing is also performed by the motor control unit 16. In addition, since the processing other than step S34 is the same as that in FIG. 5, only the processing for setting the threshold value of the maximum value of the pressing force performed in step S34 will be described here.

Here, in the third embodiment, a threshold value corresponding to a plurality of stages (for example, five stages) is set in advance. After switching to the setting mode, if an arbitrary stage is selected, in step S34, the threshold value of the maximum value of the pressing force is set based on the pressing force corresponding to the stage. In this case, it is possible to set the threshold value of the maximum pressing force or change the threshold value of the maximum pressing force because the pressing force is not measured when changing.

<Fourth Embodiment>

The electric reel according to the fourth embodiment has almost the same configuration as the first embodiment, and only the control processing method of the motor control unit 16 is different. That is, only when the motor 8 is driven by the operation of the output adjustment operation lever 9, only when the pressing operation portion 12 is pressed, the output of the motor 8 (for example, the rotation speed) is reduced or stopped according to the pressing force. This is different from the first embodiment. Therefore, only the flow of processing of the motor control unit 16 in the fourth embodiment will be described with respect to the flowchart shown in FIG. 8.

<Processing Flow of Motor Control Unit>

First, in step S41, it is determined whether the output adjustment operation lever 9 is located at a stop position (a position where the rotation of the motor 8 generated by the output adjustment operation lever 9 will not occur). When the output adjustment operation lever 9 is in the stop position, the motor control processing is not executed. If the output adjustment operation lever 9 is not at the stop position, the process proceeds to step S42.

In step S42, the motor 8 is rotated by an output (for example, a method of setting a predetermined drum rotation speed here) according to the output adjustment of the position of the operating lever 9. In addition, feedback control is performed so that a predetermined rotation speed is maintained when a load is applied to decrease the reel rotation speed.

In step S43, it is determined whether the slave pressure sensor 15 has an output of an electrical signal. If there is an electric signal output, the process proceeds to step S44.

In step S44, the output of the motor 8 is reduced in accordance with the electric signal output from the pressure sensor 15 (for example, the drum rotation speed is decelerated here). At this time, as the pressing force of the pressing operation portion 12 becomes larger, the output of the motor 8 is reduced, and even if the rotation speed of the motor 8 is reduced, the control is performed. As a result, if the angler presses the pressing operation portion 12 strongly, the rotation speed of the motor 8 set by the output adjustment operation lever 9 will be greatly decelerated, and the feeling of the angler and the rotation speed of the motor 8 will be integrated. The adjustment of the rotation speed becomes easy. Further, in a case where the rotation speed of the motor 8 is decelerated in response to the pressing force, the method of stopping the rotation of the motor 8 when the pressing force becomes maximum may be controlled.

In the fourth embodiment, as a matter of course, the threshold value of the maximum value of the pressing force in the pressure sensor 15 is provided as in the first embodiment. Set the output adjustment method.

<Fifth Embodiment>

Further, the pressing operation portion in the fifth embodiment is integrally provided to the output adjustment member 20.

The motor 8 in the fifth embodiment is arranged in front of the reel 2 as shown in FIG. 10. Except for this, the configuration is almost the same as that of the first embodiment, so only the configuration different from the first embodiment will be described below. In Figs. 10 and 11, the same components as those in the first embodiment are denoted by the same reference numerals.

The output adjusting member 20 controls a user to output a plurality of stages of the motor 8 (for example, 10 stages or more, and in this embodiment, 31 stages), and is provided on the first side plate as shown in FIGS. 9 and 10. 6a and the first side cover 7a. The output adjustment member 20 is formed in a dial shape, and is rotatably mounted on a support shaft (not shown) erected on an outer side surface of a rear portion of the case member 21 of the meter counter case 5. The rotation angle of the output adjustment member 20 in this embodiment is in a range from 80 ° to 120 °, for example. However, the rotation angle is not limited to this.

In the support portion of the support shaft of the output adjustment member 20, it is provided There are pressure sensors 15. By pressing the output adjustment member 20 in the radial direction, the motor 8 is driven by an output corresponding to the pressing force. The pressing operation portion in the output adjustment member 20 may be provided on the surface of the output adjustment member 20.

The flow of the motor control process by the motor control unit 16 when the output adjustment member 20 is pressed is the same as the flowchart shown in FIG. 4 described in the first embodiment, and the output in step S1 of FIG. 4 is Since the adjustment operation lever 9 is only replaced with the output adjustment member 20, the description is omitted.

The fifth embodiment also includes output adjustment means for arbitrarily setting the threshold value of the maximum value of the pressing force in the pressure sensor 15 as in the first embodiment. The flow of processing is the same as that of the flowchart of FIG. 5 described above, and therefore description is omitted.

<Sixth Embodiment>

Fig. 11 is a view showing an electric winder according to a sixth embodiment of the present invention. The electric winder according to the sixth embodiment is obtained by replacing the output adjustment operation lever of the first embodiment with the pressing operation portion 22. Except for this, the configuration is almost the same as that of the first embodiment, so only different configurations will be described below. In Fig. 11, the same reference numerals are assigned to the same configurations as in the first embodiment.

The pressing operation portion 22 is provided on the upper surface portion of the meter counter case 5 and is biased toward the left side of the operation switch 13, that is, the opposite side of the operation lever. Pressing the operation portion 22 is a step of outputting the output of the motor 8 in a plurality of stages (for example, 10 steps or more, in this embodiment, 31 steps) control.

The pressing operation unit 22 includes a pressure sensor 15 similarly to the first embodiment, and outputs a detected value corresponding to the pressing force as an electrical signal to the motor control unit 16 of the control unit 14. Only when the pressing operation portion 22 is pressed, the motor 8 is driven by the output corresponding to the pressing force.

<Processing Flow of Motor Control Unit>

Next, when the power of the electric winder is ON, the flow of the motor control process performed by the motor control unit 16 of the control unit 14 will be described with reference to the flowchart shown in FIG. 12.

In step S51, it is determined whether the slave pressure sensor 15 has an output of an electrical signal. If there is an electric signal output, the process proceeds to step S52. If there is no output, the motor control process is not executed.

In step S52, the motor 8 is rotated by an output (for example, a method of a predetermined drum rotation speed) corresponding to an electric signal output from the pressure sensor 15. At this time, by controlling the output of the motor 8 as the pressing force becomes larger (the drum rotation speed becomes fast here), the angle of rotation of the motor 8 will change if the angler presses the pressing operation portion 22 strongly. Quickly, since the sense of the angler and the output of the motor 8 are integrated, adjustment of the output of the motor 8 becomes easy. In addition, feedback control is performed so that a predetermined rotation speed is maintained when a load is applied to decrease the reel rotation speed.
