Description

  The present invention relates to an electric fishing reel that protects a spool motor that winds and drives a spool.

In general, when fishing for a deep fish layer such as boat fishing, an electric reel for fishing (hereinafter referred to as “electric reel”) is widely used.
As is well known in the art, an electric reel rotates a spool by driving a spool motor and winds a fishing line. Normally, an electric reel has a current of about 2.5 A (ampere) to 3 A when the spool is idle. Is energized to the spool motor. For example, when picking up a 1.5 kg red sea bream, a current of about 4 A is energized to the spool motor. In general, a motor current value of 5 A or more is overloaded for the spool motor.

  Therefore, in Patent Document 1, in order to prevent the spool motor from being overheated during a motor winding drive with a large fish on it, the performance is degraded or burned out. In addition to mounting the breaker, the breaker operating conditions in Table 1 are set and stored in advance in the storage means, and during actual fishing, for example, a current of 5 A or more is continuously supplied for 100 seconds, or a current of 5 A or more flows for 10 seconds, When this is repeated 10 times and the energization time of 100 seconds is measured, an electric reel is disclosed that operates the breaker to stop the driving of the spool motor.

The motor current value in the breaker operating conditions in Table 1 is the allowable load value of the motor current value that is overloaded to the spool motor, and 10 A that is the maximum motor current value in this breaker operating condition is referred to as the maximum allowable load value.
Further, in this electric reel, the allowable load value of the breaker operating condition is set such that, for example, the burnout limit condition (MAX) of the spool motor is 110 seconds accumulated at 10A, 120 seconds accumulated at 9A, and 140 seconds accumulated at 8A. The limit energization accumulated time corresponding to is set and stored in the storage means, and the accumulated energization time of the breaker operating condition can be arbitrarily changed within this burnout limit condition to prevent performance degradation and burnout due to overheating of the spool motor. As shown, it has a structure that can maximize the performance of the spool motor.
Japanese Patent Laid-Open No. 10-248455

By the way, during actual fishing, the hoisting load temporarily increases due to the action of waves and the pulling of fish, and accordingly, the current value required for driving the motor also increases.
However, in this case, although the spool motor is wound and driven while protecting the motor according to the above-described breaker operating conditions, the electric reel has a maximum allowable load value of a preset breaker operating condition as an upper limit. Therefore, when a fish with a weak mouth is used as a target or when the hook is shallow, there is a possibility that the force of pulling the fish is too strong, the mouth is cut and the fishhook is detached from the fish.

  The present invention has been devised in view of such a situation, and it is possible to perform a reasonable winding response according to the state of the wave, the target fish, etc. while preventing performance deterioration and burning due to overheating of the spool motor. An object of the present invention is to provide an electric reel.

  In order to achieve such an object, an electric reel according to claim 1 includes a spool motor that winds and drives a spool that is rotatably supported by the reel body, and a detection unit that detects a motor load when the spool motor is driven, Breaker that shuts off the drive circuit of the spool motor, storage means that stores breaker operating conditions set based on a plurality of allowable load values of the spool motor drive, and the maximum allowable load value within the above breaker operating conditions is arbitrarily set A setting means for selecting and setting; and a control means, which controls the spool motor in a range not exceeding the selected and set maximum allowable load value, and based on the detection value of the detection means. The spool motor can be controlled under the selected and set breaker operating conditions.

  According to a second aspect of the present invention, in the electric reel according to the first aspect, the setting means is a motor output adjuster that is mounted on the reel body and adjusts the motor output of the spool motor to increase or decrease the motor output. The feature is that the maximum allowable load value of the breaker operating condition can be selected and set by operating the regulator.

According to the first aspect of the present invention, the maximum allowable load value of the breaker operating condition under which the breaker is operated can be arbitrarily selected and set while preventing performance deterioration and burnout due to overload overheating of the spool motor. Since the force can be changed, there is an advantage that it is possible to cope with the hoisting according to the condition of the wave and the target fish.
According to the second aspect of the present invention, since the existing motor output adjuster is used as the setting means, there is no need to provide a separate switch or the like, and the entire reel can be reduced in size.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an embodiment of an electric reel according to claims 1 and 2, in which 1 is a frame body of the reel body 3, and 5 and 7 are left and right side frames 9 and 11 of the frame body 1. A spool 13 is rotatably mounted between the side plates 5 and 7 via a spool shaft supported by a well-known support portion (not shown).

  The spool 13 is rotated by driving the spool motor 15 or the winding operation of the handle 17 to wind the fishing line. The spool motor 15 is formed in a substantially cylindrical shape integrally formed between the side frames 9 and 11 in front of the spool 13. Housed in a motor case. Between the left motor shaft of the spool motor 15 and the spool shaft, a planetary speed reduction mechanism 19 including a planetary gear and a sun gear or an internal gear meshing with the planetary gear, and a power transmission mechanism 23 using the drive belt 21 are provided. They are sequentially mounted, and the driving force of the spool motor 15 is transmitted to the spool shaft through the planetary speed reduction mechanism 19 and the power transmission mechanism 23.

The spool shaft passes through the center of the spool 13 and the other end protrudes into the side plate 7, and a power transmission mechanism 25 that transmits the rotational force of the spool shaft to the spool 13 at the protruding end, A clutch mechanism 27 for switching between the clutch ON) and the spool free state (clutch OFF) is mounted.
A clutch lever 29 is attached between the side frames 9 and 11 behind the spool 13 so that the clutch lever 29 can be pressed downward. The clutch mechanism 27 is switched from clutch ON to clutch OFF by the pressing operation of the clutch lever 29. It is like that. Further, when the handle 17 is rotated in the winding direction in the clutch OFF state, the clutch mechanism 27 is returned to the clutch ON state via a well-known return mechanism (not shown). By switching the clutch ON / OFF, the spool 13 is switched between a fishing line winding state and a fishing line feeding state, and the power of the spool motor 15 and the handle 17 to the spool 13 is transmitted / cut off.

  Thus, as with the electric reel disclosed in Japanese Patent No. 2945530, the spool motor 15 is a lever-shaped motor output adjuster (hereinafter referred to as “power lever”) 31 mounted on the upper front side of the side plate 7, The power lever 31 is driven by an operation of a jogging switch (motor drive ON / OFF switch, which will be described later, the motor is turned on only when it is pressed, and the motor is turned off when it is released). 2 and 35) and is attached so as to be rotatable in the same direction as the handle 17.

  A control box 39 for accommodating a microcomputer (reference numeral 37 in FIG. 2) is installed between the side plates 5 and 7 on the upper portion of the reel body 3, and the CPU ( The control means 49 controls the winding speed of the spool 13 by continuously increasing or decreasing the motor output of the spool motor 15 from the motor stopped state to the maximum value (0 to 100%).

  In the figure, reference numeral 41 denotes a rotation detection means for detecting the rotation direction and the number of rotations of the spool 13. The rotation detection means 41 includes a pair of reed switches 43 attached to the frame 1 on the side opposite to the handle, The reed switch 43 is connected to the CPU 49 of the microcomputer 37 via the input interface 47 as shown in FIG. Yes.

  The microcomputer 37 controls and manages the program memory, the data memory, and the input / output device, and executes a calculation and transfer process necessary for processing a given job, a yarn length measurement program, and a breaker operating condition described later. ROM 51 that stores the data, RAM 53 that stores the calculation results of the CPU 49, up / down counter 55 that counts the rotation pulse signal of the spool 13 taken in from the reed switch 43, and the allowable load value of the breaker operating condition (motor A timer 57 for measuring continuous or intermittent energization time for each (specified current value), and input / output interfaces 47 and 59, which are connected to the CPU 49 via the bus 61.

A power lever 31 (potentiometer 35), an inching switch 33, and a reed switch 43 are connected to the input interface 47, and a spool motor 15 is connected to the output interface 59 via a motor drive circuit 63. Further, an alarm (notification means) 65 attached to the reel body 3 is connected to the output interface 59.
Thus, the ROM 51 incorporates a thread length measurement program similar to that of the electric reel disclosed in Japanese Patent Laid-Open No. 5-103567. In the “actual fishing mode”, the CPU 49 operates the reed switch 43. The forward / reverse determination signal of the spool 13 output from the controller 13 is taken in to determine whether the fishing line is fed out or wound, and the thread length (fishing line length) is determined by the thread length measurement program based on the count value of the up / down counter 55. The feed amount) is measured.

  The CPU 49 then displays the measured yarn length on a liquid crystal display (hereinafter referred to as “display”) 71 mounted on the operation panel 69 of the control box 39 via the display drive circuit 67 connected to the output interface 59. The fisherman can pay out the fishing line at a predetermined depth or can wind up the fishing line by operating the handle 17, the power lever 31 and the inching switch 33 while confirming the display. It has become.

  Further, as shown in FIG. 1, on the operation panel 69, a reset switch 73 and a shelf memo switch 75 having a circular shape in plan view adjacent to the display unit 71 are provided between the side plates 5 and 7 of the reel body 3. Further, the inching switch 33 which is offset from both the switches 73 and 75 is provided on the handle 17 side obliquely behind the display 71. These are connected to the microcomputer 37 as shown in FIG.

  The spool motor 15 is driven by the operation of the inching switch 33 so that a delicate shelf position adjustment and a shaving operation can be performed. However, the inching switch 33 and the power lever 31 are separate circuits, and the power When the inching switch 33 is operated during the operation of the lever 31, the spool motor 15 is driven only when the inching switch 33 is pressed, and when switching from the inching switch 33 to the operation of the power lever 31, safety is ensured. In consideration of this, the power lever 31 is configured so that the spool motor 15 cannot be driven by the power lever 31 unless the power lever 31 is returned to the position of the motor output “0”.

  Further, the side plate 5 on the side opposite to the handle is provided with a projecting portion 79 projecting downward from the front of the spool 13 so as not to obstruct the hand holding the electric reel 77. A power supply connecting portion (not shown) for connecting a power supply cord to the tip is attached. As in the prior art, a power supply cord is connected to the power supply connection portion via a connector, and power is supplied to the spool motor 15 and the like by connecting this power supply cord to a power source such as a battery.

In addition to the above-described configuration, the electric reel 77 according to the present embodiment is provided with a motor protection function that prevents the spool motor 15 from being burned out, similarly to the electric reel disclosed in Patent Document 1.
That is, the motor drive circuit 63 of the spool motor 15 is connected to a current detector 81 that detects a motor current value supplied to the spool motor 15, and the detected value of the current detector 81 is fed back to the microcomputer 37. Has been.

As described above, in this type of electric reel, a motor current value of 5 A or more is an overload for the spool motor.
Therefore, when actual fishing is started, as shown in FIG. 3, in the present embodiment, the microcomputer 37 enters the actual fishing mode (monitoring mode). The microcomputer 37 operates in the actual fishing mode. Is monitored based on the detection value of the current detector 81.

  When the value of the motor current flowing through the spool motor 15 meets one of the following breaker operating conditions, the breaker 83 attached to the motor drive circuit 63 is operated to prevent the spool motor 15 from burning out. Is stopped for a certain time, and when current less than each allowable load value flows, the energization time of all the allowable load values accumulated until then is subtracted to prevent the meaningless operation of the breaker 83. It has become.

  That is, as standard breaker operating conditions, the breaker operating conditions shown in Table 1 described in the ROM 51 are set and stored in advance at the factory shipment stage as a motor control program. The plurality of motor current values under the breaker operating conditions are the allowable load values of the motor current values that are overloaded to the spool motor 15, and the maximum motor current value of the allowable load value is 10A under the standard breaker operating conditions. This is the maximum allowable load value.

  In the actual fishing mode, for example, a current of 5 A or more is continuously supplied to the spool motor 15 for 100 seconds, or a current of 5 A or more flows for 10 seconds, and this is repeated 10 times, and the current supply time of 100 seconds is reached. When the timer 57 measures and accumulates, the microcomputer 37 or the CPU 49 activates the breaker 83 to shut off the motor drive circuit 63 and simultaneously activates the alarm 65 for 4 seconds. Thereafter, the drive of the spool motor 15 is resumed after 2 seconds.

  On the other hand, in this actual fishing mode, when a current of 3A, for example, lower than each allowable load value is energized to the spool motor 15, the accumulated value of the energization time of all the allowable load values accumulated so far. From the above, for example, if the accumulated value of energizing time of the allowable load value of 5 A or more is 45 seconds, then the current of 3 A is spooled for 10 seconds. If the motor 15 is energized, 2 seconds are subtracted from the accumulated value 45 seconds, and the accumulated value becomes 43 seconds.

FIG. 4 shows this state, and if only the current application time of the allowable load value is accumulated, the breaker operating point is reached quickly, and the operation of the breaker 83 is too sensitive so that the spool motor 15 It will stop.
However, according to the present embodiment, when the motor current value detected by the current detector 81 is lower than the allowable load value, the cumulative value of the energization time of all the allowable load values so far is subtracted by 1/5 second per second. Therefore, reaching the breaker operating point is delayed.

  Then, repeatedly adding and subtracting the energization time of each permissible load value as described above, when the breaker operating conditions are met, the breaker 83 is operated by the command from the microcomputer 37, and the spool motor 15 is stopped. The alarm 65 is activated for 2 seconds. Then, after the elapse of 2 seconds, the driving of the spool motor 15 is resumed, and it is again determined whether or not the value is lower than the allowable load value based on the motor current value fed back from the current detector 81 to the microcomputer 37. The addition and subtraction of the energization time of the allowable load value is repeated, and when the breaker operating condition is satisfied, the breaker 83 is operated and the spool motor 15 is stopped.

As described above, this embodiment also attempts to prevent performance degradation and burnout due to overheating of the spool motor 15, but under the standard breaker operating conditions described above, the maximum allowable load is 10A which is the maximum motor current value of the allowable load value. The spool motor 15 is energized with the maximum allowable load value as an upper limit, and the spool motor 15 is driven.
For this reason, as described above, when a fish with a weak mouth is targeted or when the hook is shallow, there is a possibility that the force of pulling the fish is too strong, the mouth is cut and the fishhook is detached from the fish.

  Therefore, in this embodiment, the maximum allowable load value within the standard breaker operating condition can be arbitrarily selected and set by operating the power lever 31 in order to enable a reasonable winding response according to the target fish and the like. The spool motor 15 is controlled under the changed breaker operating conditions set in this way, and the spool motor 15 is changed within a range not exceeding the maximum allowable load value selected in this way, that is, the maximum hoisting force is changed. Is limitedly driven.

That is, when the microcomputer 37 operates the inching switch 33 and the shelf memo switch 75 described above simultaneously, as shown in FIG. 3, the microcomputer 37 sequentially enters the “actual fishing mode (monitoring mode)” and the “maximum allowable load value change mode”. In response to this, characters “actual fishing” and “change” are displayed at predetermined positions on the display 71.
Here, the selection and setting method of the maximum allowable load value will be described. First, the shelf memo switch 75 and the inching switch 33 are simultaneously operated to switch the microcomputer 37 from the actual fishing mode to the maximum allowable load value change mode.

Then, the power lever 31 functions as setting means for selecting and setting the maximum allowable load value in the maximum allowable load value changing mode, and the operation allows the display 71 to display the allowable load value of the standard breaker operating condition. They are displayed sequentially.
Then, for example, if the reset switch 73 is operated when the allowable load value “7A” is displayed on the display 71, the allowable load value 8 to 10A is cut from the standard breaker operating condition as shown in FIG. Further, the breaker operating condition after the change in which the maximum allowable load value is changed to 7A is set and stored in the RAM 53.

In order to return from the maximum allowable load value change mode to the actual fishing mode, the inching switch 33 and the shelf memo switch 75 may be operated simultaneously again.
Therefore, thereafter, in the actual fishing mode, the CPU 49 of the microcomputer 37 controls the motor current value energized to the spool motor 15 to a maximum of 7 A so as not to flow any more even when a load is applied to the spool motor 15. That is, the maximum hoisting force is reduced, and the spool motor 15 is prevented from being burned out under the changed breaker operating conditions with 7A being the maximum allowable load value as shown in FIG.

  Since the present embodiment is configured as described above, in the actual fishing mode, the fishing line is fed out from the spool 13 by the clutch OFF operation of the clutch lever 29, and the spool motor 15 is driven to wind by the power lever 31 and the handle 17 is operated. The fishing line is wound around the spool 13 by the winding operation, and the shelf position adjustment and the shackle operation are performed by the operation of the inching switch 33, and the rotation detecting means 41 is operated along with the feeding and winding of the fishing line. The yarn length is measured based on the detected value, and the yarn length is displayed on the display unit 71.

  In this actual fishing mode, usually, the motor current value is monitored by the detection value of the current detector 81 based on the standard breaker operating condition, and the motor current value flowing through the spool motor 15 is as described above. When any one of the breaker operating conditions is met, the breaker 83 is operated to stop the spool motor 15 for a certain period of time. When a current less than each allowable load value is flowing, The energizing time of the value will be subtracted.

On the other hand, if it is necessary to change the maximum allowable load value of the standard breaker operating conditions according to the condition of the waves and the target fish (weak mouth, degree of hooking, etc.), the inching switch 33 and the shelf memo switch 75 is simultaneously operated to switch the microcomputer 37 from the actual fishing mode to the maximum allowable load value changing mode.
When the power lever 31 is operated, the allowable load value of the standard breaker operating condition is sequentially displayed on the display unit 71. For example, when the allowable load value “7A” is displayed on the display unit 71, the reset switch 73 is set. When the operation is performed, the allowable load value 8 to 10A is cut from the standard breaker operating condition as shown in FIG. 5, and the maximum allowable load value that has been 10A is changed to 7A, and the changed breaker operating condition is set in the RAM 53. Remembered.

Thereafter, when the inching switch 33 and the shelf memo switch 75 are simultaneously operated again to return the microcomputer 37 to the actual fishing mode and perform fishing, the CPU 49 does not turn on the spool motor 15 even if a load is applied to the spool motor 15. The motor current value to be energized is controlled to a maximum of 7A and the maximum hoisting force is controlled so that it does not flow any more, and the spool motor 15 is changed under the breaker operation conditions after changing to 7A as the maximum allowable load value as shown in FIG. This will prevent burnout.
When the maximum allowable load value is changed from “7A” to “6A”, for example, the above-described procedure may be repeated.

As described above, the present embodiment is capable of arbitrarily selecting and setting the maximum allowable load value of the breaker operating condition for operating the breaker 83 while preventing the performance deterioration and burning due to the overload overheating of the spool motor 15 so that the maximum winding is possible. Since the force can be changed, there is an advantage that it is possible to cope with the hoisting according to the condition of the wave and the target fish.
In this embodiment, since the existing power lever 31 is used as the setting means, there is no need to separately provide a switch or the like on the operation panel 69 or the like, and the control box 39 or the like can be downsized.

  As with the conventional example disclosed in Patent Document 1, the allowable limit values for the spool motor burnout limit are, for example, 110 seconds accumulated at 10A, 120 seconds accumulated at 9A, and 140 seconds accumulated at 8A. The corresponding limit energization accumulated time may be set and stored in the ROM 51, and the energization accumulated time under the breaker operating condition may be arbitrarily changed by operating the power lever 31 or the like within the burnout limit condition.

In place of the power lever 31, a change switch may be separately provided on the operation panel 69, and the maximum allowable load value may be selected and set by operating the change switch.
