JP 10-337138 A

  The operation member of Patent Document 1 changes the output of the pressure sensor according to the strength of the pressing force, and changes the spool winding speed in accordance with the output, but there are individual differences in human pressing force. Further, the pressing force may be weakened in a cold environment, and the pressing force is easily influenced by the environment in which the electric reel is operated. When the pressing force is insufficient, it becomes difficult to adjust the motor output quickly and easily.

  SUMMARY OF THE INVENTION An object of the present invention is to suppress the motor output from varying depending on the operating environment and pressing conditions in the electric reel, and to adjust the motor output quickly and easily.

  An electric reel motor control device according to one aspect of the present invention is an electric reel motor control device that drives a spool rotatably mounted on a reel body with a motor, and includes a pressing operation unit, motor control means, Output adjusting means. The pressing operation unit has a pressure sensor whose output changes according to the pressing force, and is provided on the reel body. The motor control means controls the motor output according to the output of the pressure sensor. The output adjusting means arbitrarily sets a threshold value of the maximum value of the pressing force in the pressure sensor.

  This electric reel motor control device can arbitrarily set a threshold value of the maximum value of the pressing force in the pressure sensor. For this reason, even when the motor output changes in accordance with the pressing force, variations in the motor output due to insufficient or excessive pressing force are less likely to occur, and the motor output can be adjusted quickly and easily.

  Preferably, the output adjusting means sets a threshold value of the maximum value of the pressing force based on an average value of the pressing force when the pressing operation unit is pressed a plurality of times. In this case, even if there is some variation in the pressing force, the threshold value of the maximum pressing force value is set based on the average value, so that insufficient or excessive pressing force is less likely to occur.

  Preferably, the output adjustment means sets a threshold value of the maximum value of the pressing force based on a predetermined range of the maximum pressing force when the pressing operation unit is pressed.

  Preferably, the output adjusting means sets a threshold value of the maximum value of the pressing force from among a plurality of preset pressing force values.

  Preferably, the motor control means increases the motor output as the pressing force increases. In this case, if the angler strongly presses the pressing operation portion, the motor output increases, and the angle of the angler matches the motor output, so that the adjustment of the motor output becomes easier.

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

  Preferably, the motor control device further includes an output adjusting member that is provided on the reel body and adjusts the rotation of the motor stepwise from a stopped state. The motor control means controls the motor output to the output set by the operation of the output adjustment member, and decreases the motor output according to the output of the pressure sensor when the motor is rotating by the operation of the output adjustment member.

  Preferably, the output adjusting member is a swing lever, and the motor output is adjusted stepwise according to the swing position.

  Preferably, the output adjusting member is rotatably provided on the reel body, and adjusts the motor output in a stepwise manner according to the rotation position.

  Preferably, the pressing operation unit is provided integrally with the output adjustment member, and the output of the pressure sensor changes according to the radial pressing force of the output adjustment 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, it is difficult for the motor output to vary due to insufficient or excessive pressing force. It can be adjusted quickly and easily.

It is supported freely. A clutch operating member 10 is swingably disposed behind the output adjustment lever 9. The clutch operating member 10 is a member for turning on and off a clutch (not shown) provided between the handle 3 and the motor 8 and the spool 2.

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

  The pressing operation unit 12 includes a pressure sensor 15 as shown in FIG. The pressure sensor 15 is a member that outputs an electric signal at a level corresponding to a force (hereinafter referred to as a pressing force) that presses the pressing operation unit 12, and a detection value corresponding to the magnitude of the pressing force is described later as an electric signal. Output to the motor control unit 16 of the control unit 14. When the motor 8 is not driven by the operation of the output adjustment lever 9, the motor 8 is driven at an output corresponding to the pressing force, for example, at a rotational speed only while the pressing operation unit 12 is pressed.

  As shown in FIG. 2, the control unit 14 includes a motor control unit 16 that controls the motor 8 as a functional configuration, and a display control unit 17 that controls the display unit 11 provided on the upper surface of the counter case 5. doing. The motor control unit 16 performs PWM control on the motor 8.

  A press operation unit 12 and an operation switch 13 are connected to the control unit 14. The control unit 14 is connected to the display unit 11, a spool sensor 18 for detecting the rotation speed and direction of the spool 2, and a motor drive circuit 19 for PWM driving the motor 8.

  The motor drive circuit 19 controls the drive of the motor 8 according to the operation of the output adjustment lever 9 and the pressing operation of the pressing operation unit 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 supply of the electric reel is on will be described with reference to the flowchart shown in FIG.

  First, in step S1, it is determined whether or not the output adjustment lever 9 is at a stop position (a position where the rotation of the motor 8 by the output adjustment lever 9 does not occur). If the output adjustment lever 9 is not in the stop position, the output adjustment lever 9 works in preference to the pressing operation unit 12, so that the process proceeds to step S4 and outputs according to the position of the output adjustment lever 9 (for example, here Then, the motor 8 is rotated so that a predetermined spool rotation speed is obtained. It should be noted that feedback control is performed so as to maintain a predetermined rotation speed when a load is applied and the spool rotation speed decreases. If it is determined that it is at the stop position, the process proceeds to step S2.

  In step S2, it is determined whether or not there is an electrical signal output from the pressure sensor 15. If there is an electrical signal output, the process proceeds to step S3, where the motor 8 is rotated with an output corresponding to the electrical signal output from the pressure sensor 15 (for example, at a predetermined spool rotation speed here). . If no electrical signal is output from the pressure sensor 15, the motor control process is not executed.

  In step S3, when the motor 8 is rotated with an output corresponding to the electrical signal output from the pressure sensor 15, for example, the motor 8 is controlled so as to have a predetermined spool rotation speed, and the motor 8 is increased as the pressing force increases. The rotation speed is controlled so as to increase. Thereby, if the angler strongly presses the pressing operation portion 12, the rotation speed of the motor 8 is increased, and the angle of the angler and the output of the motor are matched, so that the output of the motor 8 can be easily adjusted.

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

  In step S11, it is determined whether or not the operation switch 13 has been pressed for 3 seconds or more. If it is determined that the operation switch 13 has been pressed for 3 seconds or more, the process proceeds to step S12.

  In step S12, it is determined whether or not the motor 8 is rotating. That is, after the motor 8 stops rotating, the subsequent processing is executed.

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

  When the pressing operation unit 12 is pressed after switching to the setting mode, in step S14, a threshold value of the maximum value of the pressing force is set based on the pressing force at this time. At this time, for example, by measuring the pressing force a plurality of times and setting a threshold value for the maximum value of the pressing force based on the average value of the pressing force, the average value can be obtained even if there is some variation in the pressing force. Since the threshold value of the maximum value of the pressing force is set based on this, the pressing force is less likely to be insufficient or excessive.

Second Embodiment
The processing flow of the output adjusting means in the second embodiment of the present invention will be described with reference to FIG. Since the reel body 1 in the second embodiment has the same configuration as that of the first embodiment, description thereof is omitted. Further, the motor control process performed by the motor control unit 16 is the same as that in the first embodiment, and thus the description thereof is omitted.

  Also in the second embodiment, this process is performed by the motor control unit 16. Since processes other than step S24 are the same as those in FIG. 5, only the process for setting the threshold value of the maximum pressing force executed in step S24 will be described here. That is, in step S24, the threshold value of the maximum value of the pressing force is set based on a predetermined range of the maximum pressing force (for example, 80% of the maximum pressing force). Note that the predetermined range of the maximum pressing force is not limited to this.

<Third Embodiment>
The processing flow of the output adjusting means in the third embodiment of the present invention will be described with reference to FIG. In addition, since the reel main body 1 in 3rd Embodiment is the same structure as 1st Embodiment, description is abbreviate | omitted. Further, the motor control process performed by the motor control unit 16 is the same as that in the first embodiment, and thus the description thereof is omitted.

  Also in the third embodiment, this processing is performed by the motor control unit 16. Since processes other than step S34 are the same as those in FIG. 5, only the process for setting the threshold value of the maximum value of the pressing force executed in step S34 will be described here.

  Here, in the third embodiment, threshold values corresponding to a plurality of stages (for example, five stages) are provided in advance. When an arbitrary stage is selected after switching to the setting mode, a threshold value of the maximum value of the pressing force is set based on the pressing force corresponding to that stage in step S34. In this case, since it is not necessary to measure the pressing force when setting or changing the threshold value of the maximum pressing force, the threshold value of the maximum pressing force value can be easily set or changed. .

<Fourth embodiment>
The electric reel of the fourth embodiment is almost the same as the configuration of the first embodiment, and only the control processing method of the motor control unit 16 is different. That is, when the motor 8 is driven by the operation of the output adjustment lever 9, the output (for example, the rotation speed) of the motor 8 is reduced or stopped according to the pressing force only while the pressing operation unit 12 is pressed. Only the points differ from the first embodiment. Accordingly, only the processing flow of the motor control unit 16 in the fourth embodiment will be described here along the flowchart shown in FIG.

<Processing flow of motor control unit>
First, in step S41, it is determined whether or not the output adjustment lever 9 is at a stop position (a position where the rotation of the motor 8 by the output adjustment lever 9 does not occur). When the output adjustment lever 9 is at the stop position, the motor control process is not executed. And if the output adjustment lever 9 is not in a stop position, it will transfer to step S42.

  In step S42, the motor 8 is rotated with an output corresponding to the position of the output adjustment lever 9 (for example, at a predetermined spool rotation speed here). It should be noted that feedback control is performed so as to maintain a predetermined rotation speed when a load is applied and the spool rotation speed decreases.

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

  In step S44, the output of the motor 8 is decreased (for example, the spool rotation speed is reduced here) in accordance with the electrical signal output from the pressure sensor 15. At this time, the control is performed so that the output of the motor 8 decreases, that is, the rotational speed of the motor 8 decreases as the pressing force of the pressing operation unit 12 increases. Thereby, if the angler strongly presses the pressing operation portion 12, the rotation speed of the motor 8 set by the output adjustment lever 9 is greatly reduced, and the angle of the angler and the rotation speed of the motor 8 are matched. The rotation speed of 8 can be easily adjusted. In addition, when the rotational speed of the motor 8 decelerates according to pressing force, you may control to stop rotation of the motor 8 when pressing force becomes the maximum.

  Of course, the fourth embodiment also includes output adjusting 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.

<Fifth Embodiment>
9 and 10 show an electric reel in a fifth embodiment of the present invention. In the electric reel of the fifth embodiment, the output adjustment lever 9 of the first embodiment, which is an output adjustment member, is a rotation type output adjustment member 20. Furthermore, the pressing operation unit in the fifth embodiment is provided integrally with the output adjustment member 20. By pressing the output adjusting member 20 in the radial direction (that is, pushing the output adjusting member 20 into the inside), the motor 8 is driven with an output corresponding to the pressing force.

  The motor 8 in the fifth embodiment is disposed in front of the spool 2 as shown in FIG. Other than that, the configuration is substantially the same as that of the first embodiment, and hence only the configuration different from that of the first embodiment will be described below. 10 and 11, the same reference numerals are given to the same configurations as those in the first embodiment.

  The output adjusting member 20 is for controlling the output of the motor 8 in a plurality of stages (for example, 10 stages or more, in this embodiment, 31 stages). As shown in FIG. 9 and FIG. It is provided between the first side plate 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) that is erected on the outer surface of the rear portion of the case member 21 of the counter case 5. The rotation angle of the output adjusting member 20 in this embodiment is, for example, in the range of 80 ° to 120 °. However, the rotation angle is not limited to this.

  A pressure sensor 15 is provided on the support portion of the support shaft of the output adjustment member 20. By pressing the output adjusting member 20 in the radial direction, the motor 8 is driven with an output corresponding to the pressing force. Note that the pressing operation portion of the output adjustment member 20 may be provided on the surface of the output adjustment member 20.

  The flow of the motor control process performed 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 adjustment lever in step S1 of FIG. Since 9 only replaces the output adjusting member 20, the description thereof is omitted.

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

<Sixth Embodiment>
FIG. 11 shows an electric reel according to a sixth embodiment of the present invention. The electric reel of the sixth embodiment is obtained by replacing the output adjustment lever of the first embodiment with a pressing operation unit 22. Other than this, the configuration is almost the same as that of the first embodiment, and therefore only the configuration different from the following will be described. In FIG. 11, the same reference numerals are given to the same configurations as those in the first embodiment.

  The pressing operation portion 22 is provided on the upper surface portion of the counter case 5 and is arranged so as to be biased to the left side of the operation switch 13, that is, the side opposite to the handle. The pressing operation unit 22 controls the output of the motor 8 in a plurality of stages (for example, 10 stages or more, in this embodiment, 31 stages).

  The pressing operation unit 22 includes the pressure sensor 15 as in the first embodiment, and outputs a detection value corresponding to the magnitude of the pressing force to the motor control unit 16 of the control unit 14 as an electrical signal. The motor 8 is driven with an output corresponding to the pressing force only while the pressing operation unit 22 is pressed.

<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 supply of the electric reel is on will be described with reference to the flowchart shown in FIG.

  In step S51, it is determined whether or not there is an electrical signal output from the pressure sensor 15. If there is an electrical 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 with an output corresponding to the electrical signal output from the pressure sensor 15 (for example, at a predetermined spool rotation speed here). At this time, by controlling the motor 8 so that the output of the motor 8 increases (here, the spool rotation speed increases) as the pressing force increases, the rotation speed of the motor 8 can be increased if the angler presses the pressing operation unit 22 strongly. Since the speed of the angler is matched with the output of the motor 8, the output of the motor 8 can be easily adjusted. It should be noted that feedback control is performed so as to maintain a predetermined rotation speed when a load is applied and the spool rotation speed decreases.

  Of course, the sixth embodiment also includes output adjusting means for arbitrarily setting a threshold value of the maximum value of the pressing force in the pressure sensor 15 as in the first embodiment.

<Other embodiments>
(A) The output adjustment lever 9 in the first to fourth embodiments may be the rotary output adjustment member 20 employed in the fifth embodiment.

  (B) The output adjustment means in the fourth to sixth embodiments may be the output adjustment means in the second or third embodiment.

  (C) When the motor 8 is driven with an output corresponding to the pressing force in the fifth embodiment, the output (for example, rotational speed) of the motor 8 is set according to the pressing force as employed in the fourth embodiment. You may control to reduce or stop.

  (D) The pressure sensor 15 may be output according to a minute displacement amount of a member pressed by a spring having a large spring constant instead of a single component such as a pressure sensitive element.

  (E) In the above-described embodiment, the rotational speed of the spool 2 is detected as the motor output and feedback control is performed. However, the current supplied to the motor may be controlled so that the winding torque becomes a predetermined value. . Alternatively, the spool diameter of the spool 2 may be calculated and controlled so that the tension becomes a predetermined value. In these cases, the object to be controlled by the pressing operation unit and the output adjusting member may be changed.

  (F) The pressing operation unit 12 in the first to fourth embodiments is not limited to the one protruding from the counter case 5. Further, the pressing operation unit 22 in the sixth embodiment may protrude from the counter case 5. Moreover, the press operation part 22 is not limited to the position of the said embodiment. The counter case 5 itself may be a pressing operation unit.
