Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel type automatic fishing machine for fishing a fish hooked on a fishing hook by controlling an electric reel body, and more specifically to a tension detection for detecting a fish catch. Regarding vessels.

[0002]

2. Description of the Related Art In a fishing device using a reel,
In order to enable efficient fishing, a device for electrically determining a fish catch has already been proposed.The method is to attach a strain gauge directly to the fishing rod body and The method of determining the fish catch by detecting the deflection of the fishing rod main body using (Shokai Sho 63-186254), or the vibration applied to the fishing line wound on the spool or the vibration applied to the fishing rod is detected by the acceleration sensor. A method (Japanese Patent Laid-Open No. 287433/1988) has been proposed for determining a fish catch by detecting the fish.

[0003]

A method for detecting the deflection of the fishing rod main body or a method for detecting the vibration applied to the fishing line wound on the spool or the vibration applied to the fishing rod by using the acceleration sensor is described below. When the length of the fishing line to be extended is long, such as when the swimming layer of the fish is deep or when the tide is flowing, the resistance of seawater, weights, and amikago to the fishing line increases, so the fish catches. The change in the tension of the fishing line due to this becomes extremely small near the tip of the rod or the spool position, and the accuracy of detecting the fish catch decreases, so there is a problem that the fisherman must determine the fish catch. Was there.

The present invention was devised in order to solve the above-mentioned problems, and its purpose is to achieve a deep shelf even when the water is deep.
An object of the present invention is to provide a tension detector for a reel type automatic fishing machine capable of detecting a fish catch with high accuracy.

[0005]

In order to solve the above-mentioned problems, a tension detector in a reel type automatic fishing machine according to the present invention is a reel type which carries out fishing of a fish hooked on a hook by controlling an electric reel body. Applicable to automatic fishing machine,
Provided in the vicinity of the tip of the road thread, a sensor container whose inside is formed airtight, an opening formed in the wall of the sensor container, a diaphragm attached to the opening, and inside the sensor container. And a tension sensor that detects the pressure applied to the diaphragm and a tension transmitter that transmits the tension of Harris or the stem thread to the diaphragm.

[0006]

[Function] Since the tension of the trunk thread or Harris is transmitted to the diaphragm via the tension transmitting section, the pressure sensor for detecting the pressure applied to the diaphragm is used to detect the tension of the trunk thread or Harris due to fish catching. Changes will be transmitted. Therefore, a pressure change indicating fish catching appears in the output of the pressure sensor. Further, since the sensor container is provided in the vicinity of the tip of the yarn, the change in the tension of the trunk yarn or Harris is transmitted to the diaphragm with almost no resistance. From the above, a signal that substantially matches the tension of the fish pulling the fishing hook appears in the output of the pressure sensor.

The output 281 of 236 is sent to the drive 28. The output 221 of the display control unit 237 is given to the display unit 22.

The operation of one embodiment of the present invention will be described below. First, a partial operation of a main part will be described, and then the entire operation will be described.

The correction value calculation unit 24 outputs the output 242 to
Since the data regarding the mounting position of the electric reel body 11 on the hull 18 and the width of the hull 18 are given, the correction value calculation unit 24 determines the rod tip roller 202 based on the output of the tilt sensor 25 and the output of the acceleration sensor 26. The position change in the vertical direction is calculated and the calculation result is sent to the adder 236 as the output 241.

That is, except for the output 241 of the correction value calculation unit 24 3
When only two outputs are added, the addition result is an output that indicates the depth from the assumed water surface, which is assumed to be the water surface that does not change due to waves. Summed output (output 28 of adder 236
1) is data showing the water depth in consideration of the vertical change of the rod tip roller 202 accompanying the swing of the hull 18.

The drive unit 28, to which the output 281 is guided, outputs the output
The electric reel unit 11 is controlled so that the weight 14 is located at the depth indicated by 281.

The output of the circuit block to which the output of the pressure sensor 32 is guided is, as shown in FIG. 7, when the central portion of the diaphragm 34 is not pressed by the tension transmitting portion 35,
It operates as a depth gauge whose output value is proportional to the depth. Therefore, when the weight 14 descends or rises, the output value changes slowly,
No sudden changes occur.

On the other hand, when the fish hooks on the fishing hook 15, the diaphragm 34 is given a pressing force by water pressure and a pressing force by the pulling force of the stem thread 13 (given through the L metal fitting 35). Therefore, the output of the circuit block 361 is
If the water depth at that time is W and the output value indicating the water depth W is I1, the output value will change abruptly with the value I1 being the minimum value (indicated by 51).

Therefore, when the value changes gently, the data input section 27 sends the value at that time to the yarn feeding control section 233 and the winding control section 235 as a value indicating the water depth, and the value is changed. In the case of a sudden change, since the fish is caught, the water depth is calculated based on the state of the waveform in a certain period, and the calculation result is sent to the hoisting control unit 235. In addition, the derived value is sent to the fish catch determination unit 232 without any change.

The overall operation of one embodiment of the present invention will be described below.

By using the keyboard 21, the hull
Width of 18, mounting position of fishing rod 20, thread feed speed of road thread 12,
Shelf depth, types such as "Ayashi" or "Squatting",
Input various data such as the type of fish to be caught.
These data are stored in the data storage unit 231, sent to the display control unit 237, and displayed on the display unit 22.

When the above initial setting operation is completed, each fish hook
The bait 15 is fed, the fishing rod 20 is tilted to the sea surface side, and the hook 15 that has finished feeding is thrown toward the sea surface. After that, the operation start is input using the keyboard 21.

The yarn feeding control section 233 feeds the road yarn 12 at the set yarn feeding speed, and the pressure sensor 32
Interpolation calculation is performed based on the water depth from the signal from the motor (given as output 271) and the output 282 indicating the payout length from the electric reel body 11 (based on the thickness of the line thread 12, the spool diameter and the number of revolutions). To do. Then, the calculated value is sent to the display control unit 237 as the water depth to display the value on the display unit 22. That is, the water depth of the sinking weight 14 is displayed on the display unit 22 every moment.

When the calculated water depth approaches the set shelf depth, the yarn feed speed is gradually reduced, and when the set water depth is reached, the yarn feed is stopped. Then, the invitation control unit 234 is instructed to start the operation.

The invitation control unit 234, to which this instruction is given,
From the data programmed in advance for each fish species, according to the data corresponding to the set fish species, the electric reel unit
By alternately repeating the winding of the road thread 12 by 11 and the thread feeding, the fish hook 15 is given an invitation such as "Ayashi" or "Chaku" corresponding to the target fish.

At this time, when the road thread 12 swells due to the influence of the tidal current and the water depth of the fishing hook 15 changes, the change is indicated by the output 271. Therefore, the thread feeding control unit 233 causes the electric reel body 11 to feed the thread. By letting you do the fishing hook
The water depth changes of 15 are automatically corrected.

When the fish hooks on the fishing hook 15 by the lure motion accompanied by the correction of the water depth, the diaphragm 34 causes the trunk thread.
It is pressed by the tension of 13. Therefore, a waveform 51 indicating fish catching appears in the output 271 indicating the signal from the pressure sensor 32. The fish hook determination unit 232 makes the judgment based on the waveform. This judgment is performed based on the tension waveform change and the fish hook judgment load that are programmed in advance for each fish species. Be seen. When it is determined that the fish is caught, the hoisting control unit 235 is instructed to start the hoisting operation, and the display control unit 237 is notified that the fish has been caught.

Display control unit informed that fish was caught
The 237 informs the angler that the fish has been caught by controlling the buzzer provided in the display unit 22 to ring.

Further, the hoisting control section 235, to which the instruction to start the hoisting is given, sends the stem thread 13 sent from the weight 14 and given by the output 271 in order to prevent the mouth of the fish from being cut off and the slack of Harris at the same time. The tension of the electric reel body 11 is adjusted so that the tension is within a pre-programmed range (the output 282 indicating the payout length from the electric reel body 11 is constantly referenced to perform the calculation for removing the influence of the water depth). The fish hooked on the hook 15 is pulled toward the water surface while controlling the hoisting speed of.

Then, according to the output 282 from the electric reel body 11, when it is detected that the fish is drawn near the water surface, the fish is further drawn while controlling the winding speed of the electric reel body 11 to be reduced. When the fish is pulled to the berth, the winding operation of the electric reel body 11 is stopped. Then, the display control unit 237 is notified that the drawing is completed. Therefore, the display control unit 237 sounds the buzzer in the display unit 22 and blinks the LED indicating the end of the pulling to notify the angler of the end of the pulling.

The angler who has been informed by the above display that the pulling of the fish has been completed, depending on the fish caught, takes in the tie net in some cases or pulls up the stem thread 13 in some cases to take in the fish. Then, the above-mentioned operation is restarted by feeding the fishing hook 15 again, throwing it in, and inputting the operation start again.

During the above operation, the hull is affected by waves.
Due to the change in the position of the rod tip roller 202 caused by the ascent and descent of the 18 and the rolling of the hull 18, an error will be added to each of the above controls. The error value is constantly corrected by the output 241 of the correction value calculation unit 24 given to the adder 236 which is sent out.

As described above, since the pressure sensor 32 is also configured to detect the water depth, when the water depth of the weight 14 changes due to the influence of the tidal current, the correction can be performed.

The present invention is not limited to the above-mentioned embodiment, and the case where the liquid to be injected into the liquid injection portion 371 is silicon oil has been described, but other liquids such as mercury and NaK may be used. It is possible.

Regarding the operation by the hoisting control section 235, the case has been described in which the tension of the trunk yarn 13 is monitored and the hoisting speed is controlled so that the tension is within a certain range. As another configuration, for example, a configuration such as constant-speed winding in which the winding speed is constant is possible.

Although the opening has been described as being formed on the side surface, the other direction is as follows.
For example, it can be formed on the lower surface or the like, and in this case, the tension transmitting portion is a sulcan mounting fitting attached to the surface of the diaphragm 34.

Further, although the case where the trunk yarn 13 is attached to the tension transmitting portion 35 has been described, it is possible to directly attach Harris as another configuration.
