Abstract

PURPOSE:To hook up a fish under inhibition of runaway thereof by winding up a spool in a rotational number suitable for a pulse-duty ratio in naturally decreasing a rotation number for strong pulling of the fish and increasing the rotation number for weak pulling of the fish, with rotating a motor in a pulse- duty ratio of a pushed switch. CONSTITUTION:A fish is caught and, e.g., a switch 11 of a 50 % pulse-duty ratio is pushed, then a signal winding-up in said pulse-duty ratio is outputted to a motor-driving means 4 and an indicating means 16 by a minimum rotation number-ensuring means 10. By said process, a motor 3 is rotated by the driving means 4 in 50% on-time and 50% off-time and a wound-up state at 60% pulse- duty ratio is indicated in the indicating means 16. In a judging means 9, an L-signal for a time sent from a pulse interval-measuring means 8 longer than a fixed time, or an H-signal for a time shorter than the fixed time, is subjected to feedback to the ensuring means 10. In the ensuring means 10, the pulse-duty ratio is gradually increased from 60% to 100% for the L-signal and the pulse- duty ratio is gradually increased for varying to the H-signal.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric reel used for fishing.

Conventional technology Conventionally, this type of electric fishing reel has been used to reel in quickly when the fish is not being caught, and when the fish is being caught, it is reeled in gradually depending on the condition of the fish, thereby preventing the fish from getting cut. Functions are being added and higher value-added control is being performed. The method of controlling the rotational speed of the spool in controlling these electric reels is to control the pulse duty ratio of the voltage applied to the motor.
A typical example is a method of realizing each stage of spool rotational speed. However, the method of simply controlling the pulse duty ratio has a problem in that the motor stops even with a relatively small load torque when the spool is rotating at a low speed.

Below, the voltage applied to the motor with pulse du 3,\-

This will be explained using figures. In FIG. 2, 21 is a reverse connection prevention diode, 22 is a stabilizing power supply circuit for supplying a stable voltage to the control system circuit, and 23 is a spool driving motor when winding the yarn. 24 is a motor drive means for driving the motor 23, and 25 is a pulse duty ratio control means for outputting pulses to the motor drive means 24 with reference to information from switches 26 and 27. 26 is a switch for winding at a pulse duty ratio of 50 inches, 27 is a switch for winding at a pulse duty ratio of 100 inches, 2
8 is means for displaying the state of the pulse duty ratio when winding up the spool.

Next, the operation of the pulse duty ratio control of the electric reel configured as shown in FIG. 2 will be explained. First, let out the fishing line and lower the bait to the ledge where you can catch fish. At this time, if you can't catch a fish, the pulse duty ratio is 1, which allows you to quickly replace the bait and reel it in as soon as possible.
Press the 00% switch 2γ. The pulse duty ratio control means 25 recognizes the information of this switch 27 and outputs a signal to the motor drive means 24 and display means 28 to wind the motor at a duty ratio of 100%. In response to this, the motor drive means 24 rotates the motor 23 at 100% on time to wind up the spool, and the display means 28 displays a pulse duty ratio of 10.
Displays the state where the winding is being carried out at 0. ! Similarly, if you catch a fish and reeling the fish in at a high speed may cause a break, you may want to reel the spool relatively slowly, so switch 2 with a pulse duty ratio of 50.
Press 6. The pulse duty ratio control means 25 recognizes the information of this switch 26 and outputs a signal to the motor drive means 24 and display means 28 to wind the motor at a pulse duty ratio of 50 degrees. In response to this, the motor drive means 24 drives the motor 2.
3 is rotated with an on time of 50 and an off time of 50 to wind up the spool, and the display means 28 shows a pulse duty ratio of 50.
Displays the state in which it is being hoisted by the person in charge.

Problems to be Solved by the Invention However, in the conventional configuration described above, when the spool is wound up with a pulse duty ratio of 50%, as shown in Figure 4, 6.4, compared to when it is rotating with a pulse duty ratio of 100, However, since the locking torque of the motor is low, if the tension applied to the spool becomes large, the spool will stop at an early stage and control suitable for actual fishing cannot be performed.

The present invention solves the above-mentioned conventional problems. By rotating the motor at the pulse duty ratio of the pressed switch, when the fish pulls strongly, the rotation speed naturally decreases, and when the fish pulls weakly, the rotation speed decreases. By raising the spool and winding up the spool at a rotation speed that matches the pulse duty ratio, you can catch fish without letting them escape. Even if you press the selection switch,
The object of the present invention is to provide an electric fishing reel that prevents the spool from stopping and ensures a minimum rotational speed by making the locking torque of the motor equal to that when the pulse duty ratio is 100%.

6. Means for solving the vane problem In order to achieve this object, the electric fishing reel of the present invention includes a driving means that turns the motor on and off at n types (n≧2) of pulse duty ratios; a switch that enables selection of the n types of pulse duty ratios when winding the spool; a pulse generating means that generates the number of pulses based on the number of rotations of the spool; and a first pulse generated by the pulse generating means when winding the spool. It consists of a pulse interval measuring means that measures the time until the second pulse is generated, and a determining means that generates a signal when the pulse interval exceeds a certain time. It is comprised of a minimum rotational speed ensuring means that prevents the spool rotation from stopping by controlling the driving means so that the on-time of the on-off time shifts to a pulse duty ratio that is one step longer.

This configuration rotates the spool with the selected pulse duty, even if the spool rotational speed is about to drop below a certain guaranteed value due to catching a too large fish or the pulling force of the 7-pen fish being too strong. By controlling the drive means so that the on time of the on and off times of the pulse duty ratio shifts to a pulse duty ratio that is one step longer, it prevents the spool from stopping, guarantees the minimum rotation speed, and locks the motor. It is possible to always make the torque equal to that with a duty ratio of 100%.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings. In FIG. 1, 1 is a reverse connection prevention diode, which is connected to a power source battery. 2 is a stabilizing power supply circuit for supplying stable voltage to the control system circuit;
Reference numeral 3 denotes a spool driving motor during yarn winding. 4 is a motor driving means for driving the motor 3; 5, 6.7;
are three sensors that detect the rotation of the spool and output it as a pulse. 8 is a pulse interval measurement that inputs pulses from sensors 5, 6.7 to detect the forward and reverse rotation directions of the spool and measures the time from the first pulse generation to the second pulse generation when the spool is in the winding state. 9 is a determining means that generates a signal when the pulse interval measured by the pulse interval measuring means 8 exceeds a certain period of time. Reference numeral 10 designates a minimum rotation speed ensuring means that receives the signal from the determination means 9 and controls the motor drive means 4 so that the on-time of the pulse duty ratio shifts to a pulse duty ratio that is one step longer;
is a switch that winds up with a pulse duty ratio of 60%, 1
2 is a switch that winds up with a pulse duty ratio of 60%,
13 is a switch that winds up the winding at a pulse duty ratio of 70%, 14 is a switch that winds up at a pulse duty ratio of 80, and 16 is a switch that winds up at a pulse duty ratio of 100%. 16 is means for displaying the state of the pulse duty ratio when winding up the spool.

The operation of the electric fishing reel constructed as above will be described below. Let out the line and lower the bait to the ledge where you can catch fish. At this time, if you do not catch any fish, you want to quickly change the bait, so press the switch 15 for Pulse Du 9 Page 1 Tee Ratio 1oo% to quickly reel in the bait. The minimum rotation speed ensuring means 1o recognizes this switch 15 and outputs a signal to the motor drive means 4 and display means 16 to wind the motor at a duty ratio of 100%. In response to this, the motor drive means 4
Winding with pulse duty ratio 1oo%, display means 16
indicates that the winding is being performed with a pulse duty ratio of 100. Similarly, if a fish is caught and the target fish may break if reeled in at a high speed, the pulse duty ratio can be adjusted to 50% depending on each target fish in order to reel the spool relatively slowly. Select the switch from section 80 to section 80. here 50
When the switch 11 with a pulse duty ratio of % is pressed, this switch information is recognized by the minimum rotational speed ensuring means, and a signal is output to the motor driving means 4 and the display means 16 to wind the motor at the pulse duty ratio. In response to this, the motor drive means 4 rotates the motor 3 with an on time of 50% and an off time of 50%, winds up the spool, and displays the display means 16 in a state of winding with a pulse duty ratio of 50% 1o7. -Display the page. When the motor 3 starts rotating, the spool rotates, and the sensors 5, 6.7 attached equally to the spool
generates a signal according to the rotational speed of the spool. The pulse interval measuring means 8 measures the time from the first pulse generated by the sensor to the generation of the second pulse,
The signals are output one after another to the determining means 9. The determining means 9 makes a comparison with a predetermined fixed time, and if the time sent from the measuring means 8 is longer than the fixed time, it will send an L signal, and if it is less than the fixed time, it will send an H signal to guarantee the minimum rotation speed. Feedback is provided to the means 1o. In response to this, the minimum rotation ensuring means 10 determines that when the signal sent from the determining means 9 is an L signal, the pulse duty ratio of the voltage applied to the motor is 60%.
(On time 60q6. Off time 40%), a signal for winding up the spool is output to the motor driving means 4, and the motor is rotated with a pulse duty ratio of 60%. If the signal sent from the determining means 9 continues to be an L signal, the pulse duty ratio is set to 70% and 80%.

Gradually increase it to 100chi, and send from judgment means 9 to 117
<- When the incoming signal changes to an H signal, the minimum rotation speed for winding the spool can be guaranteed by gradually lowering the pulse duty ratio until it reaches the pulse duty ratio of the switch that is being pressed at that time. can.

As described above, according to this embodiment, when a fish that is too large is caught or the pulling force of the fish is too strong, no matter what pulse duty ratio selection switch is pressed, the lock torque of the motor is changed as shown in FIG. Pulse duty ratio 1
By making it equal to the time of 00, it is possible to prevent the spool from stopping and easily guarantee the minimum rotation speed.

Effects of the Invention As described above, in the line winding operation of an electric fishing reel, the motor is rotated at the pulse duty ratio of the pressed switch, so that when a fish is strongly attracted, the rotation speed is naturally reduced. By winding up the spool at a faster rotation speed that matches the pulse duty ratio when the pull of the fish is weak, you can catch the fish without letting it escape. Even if the ratio selection switch is pressed, by making the motor lock torque equal to that when the pulse duty ratio is 100%, the spool can be prevented from stopping and the minimum rotation speed can be guaranteed.
