Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a novel spool stop mechanism in a depth storage device for a fishing reel, which stops the spool by rotating the drive motor by a certain amount when the storage depth is reached. The technical feature is that the free rotation of the spool is stopped by activating an auto-return type clutch mechanism.

[Conventional technology and its problems]

-a. In boat fishing and deep sea fishing, fishing is carried out while searching for the species of fish, but when using an electric reel to lower the line again to the position of the fish species that has been detected by a fish signal, it is difficult to When winding up the line, the number of revolutions of the spool (corresponding to the depth of the fish species) is detected by a sensor, stored and processed by a microcomputer, and when the line is re-reeled, a separately installed spool stop mechanism is activated according to the memorized depth. Depth storage devices that can always obtain a constant payout length by actuation have already been developed (for example, the Utility Model Act of 1983
(Refer to Publication No.-10046).

However, in general electric reels, by rotating a control lever, the pressure contact force between the spool and the friction plate that rotates it is adjusted, and the rotation and stopping of the spool can be controlled in stages. Since the friction plate, which is connected to the motor via the deceleration mechanism or the like, is located on the opposite side of the control lever or the like, it is difficult to interlock the spool stop mechanism with the core.

Due to the structural reality, the spool stop mechanism in the conventional depth storage device of this type of electric reel is, for example,
The free rotation of the spool is stopped by engaging a ratchet gear fixed to one side of the spool with a ratchet pawl that rotates via a solenoid activated by a signal from a microcomputer, multiple cams, etc. Since it was necessary to add separate mechanisms to the reel, the structure was complicated, required assembly precision, and the reel as a whole became large and heavy. It is something.

On the other hand, in the case of a manual reel, the clutch shaft is elastically slid by operating the clutch lever, and the spool can be switched between a free state and an engaged state, and the clutch shaft is momentarily moved when the drive shaft starts rotating. It is common to have a reel equipped with a so-called auto-return clutch mechanism that returns the spool to the engaged state and returns the spool to the winding state, but it is not equipped with the depth memory device described above. When lowering the fishing line again to the position of the fish species that has been detected, the angler must manually operate the fishing line using the length measurement mark attached to the fishing line or the count display on a counter that is linked to the feeding of the fishing line as a guide. Therefore, it was difficult to keep an eye on the route and counters, and not only did it require a great deal of will power to set the fish species, but there were also problems in that mistakes were often made and accuracy was lacking. It is something.

[Means for solving problems]

In view of these circumstances, the present invention provides a spool stop mechanism in a depth storage device for a fishing reel, which includes a counting section that counts the number of rotations of the spool via a sensor, a storage section that stores the counted value, and a fishing reel. A central processing unit that compares and processes the count value when re-feeding the and the above-mentioned stored value and outputs a predetermined drive motor control signal, a motor control unit that rotates the drive motor by a certain amount based on the signal, and a motor control unit that operates in conjunction with the drive motor. The various problems mentioned above are solved at once by comprising an auto-return type clutch mechanism in which the clutch shaft automatically returns to the engaged state with the spool when the drive shaft starts rotating.

[For production]

The spool stop mechanism of the present invention, which has a ridged structure, counts the number of revolutions of the spool through a sensor when winding the thread.
This is stored in the storage unit, and when the thread is fed out again, the central processing unit compares the count value of the free rotation of the spool with the above-mentioned stored value, and when the two values match, a motor control signal is output. The drive motor rotates the drive motor by an amount that allows the drive shaft to automatically return the clutch shaft, and the clutch shaft engages the spool to stop its free rotation.

〔Example〕

Hereinafter, the spool stop mechanism of the present invention will be described in more detail based on embodiments shown in the drawings.

(Part 1) FIG. 1 shows an embodiment of an electric reel, and in the figure, 1 indicates a drive motor for winding a yarn, which rotates a drive shaft 4 via a group of reduction gears 2 and a connecting gear 3; Reference numeral 5 denotes a master gear which rotates together with the drive shaft 4 via a multi-disc clutch 7 held by a drive lever 6, and rotates the drive lever 6 to adjust the pressure contact force against the multi-disc clutch 7. This makes it possible to control the rotational torque of the rotating spool 8 via the clutch mechanism described above.

Next, 9 moves the clutch shaft 11 by operating the clutch lever 10.
By elastically sliding in the axial direction, the spool 8 can be switched from the free state to the engaged state, and the release mechanism 12, which operates in conjunction with the rotation of the drive shaft 4, automatically returns to the engaged state instantaneously. This is a so-called auto-return type clutch mechanism in which the clutch pinion 13 meshes with the master gear 5.

Next, reference numeral 14 is a microcomputer, and as shown in FIG. A storage unit 17 that stores the counted value, a central processing unit 18 that compares and processes the counted value when re-feeding the thread with the stored value and outputs a predetermined motor drive signal, and controls the drive motor 1 at a constant level according to the signal. It is composed of a motor control section 19 etc. that rotates the motor by a certain amount.

Further, 20 indicates a control panel equipped with operation buttons 20', etc., and 21 indicates a power source such as a storage battery.

It goes without saying that the microcomputer 14 can also be used for automatic speed change control of the drive motor during yarn winding, automatic jerking control, etc. employed in ordinary electric reels. Further, as a sensor for detecting the rotational speed of the spool 8, any sensor can be selected, such as a non-contact type using a photoelectric element, a Hall element, etc., or a contact type.

Therefore, when fishing, we wait for the fish to appear while fishing near the species of fish, but when a fish appears and we wind up the fishing line, we press the operation button 20゛ in advance to start counting, and then start the drive. A normal winding operation is performed by the motor 1, and the number of rotations of the spool (winding length of the thread) at the end of winding is stored in the storage section 17.

Next, when setting the fishing line to the depth of the fish species where the above-mentioned fish information was found again, use the clutch lever 10 to release the spool 8 to the free state, let out the fishing line, count the number of revolutions at that time, and record the number of rotations at that time. When the numerical value is reached, the central processing unit 18 outputs a predetermined drive motor control signal, and the motor control unit 19 uses this signal to drive the drive shaft 4 by an amount sufficient to activate the release mechanism 12 of the auto-return type clutch mechanism. When the motor 1 is rotated, the protrusion 12a of the release mechanism pushes the guide plate 12b to release the lifting plate 11a of the clutch shaft, and the clutch shaft 11
is elastically automatically returned to engage the spool 8, and the rotation of the spool is stopped.

(Part 2) FIG. 3 shows another embodiment of the present invention, in which a manual reel equipped with a conventional auto-return type clutch mechanism and a drive motor 1 controlled by the above-mentioned microcomputer etc. are connected to a deceleration mechanism 22, This is a manual/electric fishing reel that is interlocked via a drive shaft 23 and a connecting gear 3. Rotating the spool 8 by
(The handle 24, which is equivalent to 1 and is attached to one end of the drive shaft 4, allows the drive shaft 4 to be rotated during manual operation by means of a one-way mechanism 25 composed of, for example, a ratchet, and when the drive motor is operated. , so as not to rotate together with the drive shaft.

Furthermore, the speed reduction mechanism 22 is connected to the drive shaft 23 with a roller clutch 26 interposed at its terminal end, for example, as shown in FIG. 4, and the rotational force of the drive motor 1 is However, the rotational force of the drive shaft due to rotation of the handle during manual operation is not transmitted to the drive motor 1 side.

When repaying the thread, the drive motor 1 is rotated by a certain amount in accordance with the signal processed by the microcomputer 14, and the spool is released via the auto-return type clutch mechanism 9, as in the first embodiment. The rotation can be stopped automatically.

[Effects of the Invention] As described above, the spool stop mechanism in the fishing reel depth memory device of the present invention normally rotates the drive motor used for winding a certain amount when the line reaches the memorized depth. By doing so, an auto-return type clutch mechanism is activated and the free rotation of the spool is stopped, so there is no need to provide an additional mechanism that combines parts such as solenoids and cams as in the past. In addition to the extremely simple structure, the reel as a whole can be made smaller and lighter, which is expected to have an exceptional effect.

Furthermore, the spool stop mechanism according to the present invention is adapted to stop the rotation of the spool by using an auto-return type clutch mechanism that is generally equipped on manual reels. Various effects can be expected, such as the fact that the combinations can be performed extremely easily and with a simple configuration.
