JPH0530883A - Fishing reel - Google Patents

Abstract

PURPOSE:To provide a fishing reel causing little snagging trouble even in the case of setting a fishing depth near the sea bottom and enabling easy setting of the fishing depth. CONSTITUTION:The objective reel is provided with a clutch mechanism to be switchable between a state to allow the delivery of a fishing line from a spool and a state to inhibit the delivery and a sensor to measure the tension of the fishing line delivered from the spool. When the fishing line is delivered from the spool by the clutch mechanism and a tackle reaches the bottom to decrease the tension of the line below a prescribed level, the state is detected by the sensor and the clutch mechanism is switched to the delivery-inhibition state by a controller.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel,
Specifically, under the situation where the fishing line is being paid out from the spool due to the weight of the work in progress, such as when the work in progress is input in boat fishing,
The present invention relates to a technique for automatically stopping this feeding.

[0002]

2. Description of the Related Art The means constructed as described above is called an automatic shelf stop mechanism. Conventionally, as a reel provided with this mechanism, there is one disclosed in Japanese Patent Laid-Open No. 63-248328. In the conventional example, the amount of fishing line delivered from the spool is obtained by measuring the amount of rotation of the spool,
When the delivery amount reaches a predetermined value, the clutch mechanism is turned on and off to prevent the spool from rotating.

[0003]

Considering a conventional reel, in this type of reel, a clutch (operating means) is disengaged at the time of inputting a work in process to freely rotate the spool by the weight of the work. The fishing line is paid out,
For reels equipped with an automatic rack stop mechanism, the amount of rotation of the spool is measured at the time of this payout to obtain the amount of fishing line to be taken out from the spool, and the work in advance is set based on this amount of payout. When it is determined that the depth of the shelf has been reached, the actuator is actuated to engage and operate the clutch to prevent the fishing line from being fed out.

However, assuming that the depth of the shelves is not set as in the case where the tackle is loaded for the first time at the time of actual fishing, in such a situation, when the tackle reaches a desired depth, the above-mentioned method is used. It is impossible to stop the feeding of the fishing line by activating the automatic rack stop mechanism, and there are many cases where the fishing line is excessively fed, and improvement is desired. In addition, in fishing performed by setting a shelf at a depth near the seabed, the depth of the shelf often changes each time the boat is moved, which not only causes the same inconvenience as described above, but also makes it possible to obtain a depth near the seabed. In the case of fishing in, if the fishing line is not stopped when the tackle reaches the seabed, the fishing line is excessively fed out, and as a result, there is room for improvement due to the possibility of negatively sticking.

Conventionally, when fishing is performed at a depth near the sea bottom without setting the depth of the shelves, it is determined from the state of dandruff that the tackle has reached the sea bottom after the tackle is loaded. A person grasps and operates the clutch artificially, and after this,
By performing an operation of winding a predetermined amount of fishing line, it requires a relatively long work such as setting a work in process to a desired depth. It is an object of the present invention to reasonably construct a fishing reel that is less likely to cause negative spots even when a shelf is set near the seabed and fishing and that does not take time for shelving.

[0006]

The first feature of the present invention is that the operating means is configured so as to be switchable between a state in which the fishing line is allowed to be drawn out from the spool and a state in which the fishing line is prevented from being drawn out, and the fishing line is drawn out from the spool. When each sensor for measuring the tension of the fishing line is provided, and when the sensor measures that the tension of the fishing line has reached a predetermined value or less while the fishing line is being paid out from the spool by the operating means, the operating means is The present invention is characterized in that it is provided with a control means for switching to a fishing line payout preventing state, and a feature of the second invention is that the fishing line is allowed to be paid out from the spool.
In a state in which the operating means configured to be switchable to a blocking state and the sensors for measuring the tension of the fishing line fed from the spool are provided, and the fishing line is fed from the spool by the operating means,
When the sensor measures that the tension of the fishing line has changed according to a preset characteristic, it is provided with control means for switching the operating means to the fishing line payout prevention state, and the action and effect are as follows. Is.

[0007]

When the feature of the first invention is configured as shown in, for example, FIGS. 1 to 7, the device is put in even when the depth of the shelves is not set as in the case where the device is put in for the first time in boat fishing. After that, when the weight of the work in progress bottoms, the control means 36 discriminates the bottom bottom based on the signal value of the sensor S, and switches the operating means C to the fishing line feed-out preventing state. Further, according to the feature of the second aspect of the invention, like the above-mentioned case, when the tackle is not set for the first time in boat fishing, even if the depth of the shelf is not set, after the tackle is thrown in, the control means 36 controls the tackle. The tension of the fishing line 4 at the time of descending is measured and held by the signal of the sensor S, and the value of the tension thus held is compared with the value of the tension subsequently measured by the sensor S. As a result of this comparison, when a value smaller than the value of the held tension is measured, it is determined that the bottom of the work is in progress, and the operating means C is switched to the fishing line feeding-out prevention state. As shown in the flowchart of FIG. 1, these control operations are performed by the # 1
When the tension value reaches an absolute value such as 06 step and # 107 step, the operation means C such as the clutch mechanism is switched and operated. In the second invention, the # 103 step and the # 104 step are performed. As described above, when the tension value is lower than the value held in the memory or the like, the operating means C such as the clutch mechanism is switched based on the change in the relative tension value. In other words, each of the inventions causes the fishing line 4 to be prevented from being fed out by judging the bottom of the work on the basis of the tension of the fishing line 4 even if the angler does not perform a special operation. The harmful effect can be suppressed.

[0008]

Therefore, when fishing is carried out by lowering the tackle near the seabed, negative fishing is less likely to occur even if the depth of the shelf is not set, and the shelving is not troublesome. Could be reasonably configured.

5, a control device 36 (an example of control means) composed of a microprocessor and a length sensor 37 composed of a pair of reed switches are installed. The length sensor 37 is a spool as shown in FIG. 5 counts the number of rotations of the spool 5 under the effect of magnetism of a magnet 39 embedded in the wheel 38 that meshes with the gear portion 5A of the gear 5, and the control device 36 records the count result and preset data. Based on this, the amount of the fishing line 4 fed out from the spool 5 is obtained and output to the liquid crystal display 33.

When the shading switch 35 is turned on, the electric motor 10 is driven to raise the work in process by a predetermined amount, and the bait is released from the work in-process basket. In this reel, an automatic shelf for automatically entering and operating the clutch mechanism C to prevent the fishing line 4 from being fed out when the work in process reaches a predetermined shelf depth after the work in process is put in, and when the work in process reaches the bottom. It has a stop mechanism.

That is, as shown in FIG. 2, this mechanism is composed of a length sensor 37, a tension sensor S, an electromagnetic solenoid 26, a clutch sensor 27, and a control device 36, and the operation thereof is as shown in the flow chart of FIG. The tension sensor S

This signal value is stored in the memory 36 of the controller 36 as time passes.
A is held and the change characteristic of the held data is set, and the averaging process is performed to compare the thus obtained characteristic and processing result with the newly input tension value. When the decrease in the tension value is recognized, the electromagnetic solenoid 26 is driven to engage and operate the clutch mechanism C,
After the clutch sensor 27 determines that the entering operation is completed, the electric motor 10 inside the spool is driven to raise the work in process by a predetermined amount (steps # 101 to # 104 and steps # 108 to # 11).
0 steps).

Incidentally, in this control, as shown in the graph of FIG. 3, the change characteristic of the tension of the fishing line 4 is preliminarily set so that the tension acting on the fishing line 4 is not influenced by the phenomenon that it changes at a constant cycle due to the vertical movement of the fishing boat. In the control described above, as shown in FIG.
When the tension of a low value T ₁ is measured away from the average tension value, it is determined that the work has bottomed out, and the clutch mechanism C is engaged and operated. Next, if the decrease in the tension value is not recognized, it is determined whether or not the shelf is set, and if the setting is not made, the tension of the fishing line 4 is further set to the preset value T ₁ . Is compared to obtain a value T ₂ smaller than this value T _1.
When the clutch mechanism C is reached, the clutch mechanism C is operated to be engaged by driving the electromagnetic solenoid 26 and the clutch sensor 27 determines that the engagement operation has been completed. The electric motor 10 inside the spool is driven to raise the work in process by a predetermined amount (steps # 106 to # 110).

Incidentally, in this control, as shown in the graph of FIG. 3, the tension acting on the fishing line 4 is smaller than the value of the tension for engaging the clutch. or,
If it is determined in step # 105 that the shelves are set, the signal from the length sensor 37 is input, and the electromagnetic solenoid 26 is driven only when the depth of the shelves to which work is set is reached. Thus, the clutch mechanism C is operated to be engaged, and the clutch sensor 27 determines that the engagement operation is completed, and then the operation is terminated (steps # 111 to # 114).

[Other Embodiments] In addition to the above embodiments, the present invention is
For example, in the situation where a shelf is set near the seabed, when the tension of the fishing line decreases when the work in progress is lowered to the vicinity of this shelf, even if this decrease in tension is slight, the clutch mechanism can be operated. It is possible to configure the control system so as to perform the entry operation, and it is also possible to apply to a reel of a manual hoist type without an electric motor.
