Description

Description: TECHNICAL FIELD The present invention relates to a novel spool stop mechanism in a depth storage device for fishing reels, and by rotating a drive motor by a certain amount when the storage depth is reached, The technical feature is that the auto-return type clutch mechanism is operated to stop the free rotation of the spool.

[Conventional technology and its problems]

Generally, in boat fishing and deep-sea fishing, fishing is performed while searching for the fish rack.However, when the fishing line is lowered again to the position of the fish rack that was once detected by fishery etc. A sensor detects the number of rotations of the spool (corresponding to the depth of the fish rack) at the time of winding, and the microcomputer stores and processes it. When the reel is re-wound, the spool stop mechanism separately provided according to the above-mentioned memory depth is operated. Have already developed a depth memory device that can always obtain a constant payout length (for example, Jikkou Sho 5).
8-10046).

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

From such a structural reality, as a spool stop mechanism in a conventional depth memory device of this kind of electric reel, for example,
Stop the free rotation of the spool by engaging the ratchet gear fixed to one side of the spool with a ratchet claw that is rotated by a solenoid operated by a signal from a microcomputer and a plurality of cams, etc. Since it was necessary to add a separate mechanism such as the one described above, the structure was complicated and assembly accuracy was required, and the problem was that the reel as a whole became large and heavy. Is.

On the other hand, in the case of a manual reel, the clutch shaft can be elastically slid by operating the clutch lever to switch the spool to a free or occlusal state, and the clutch shaft can be momentarily moved when the drive shaft starts rotating. A reel equipped with a so-called auto-return type clutch mechanism that returns the occlusal state and puts the spool in a winding state is common, but the depth memory device as described above is not provided, and When the line is lowered again to the detected position of the fish rack, it was manually operated by the fisherman with reference to the side length markings attached to the line in advance and the counting display such as the counter linked with the line feeding. However, not only is it impossible to keep an eye on the thread and the counter, it is necessary not only to take great care in setting the fish rack, but also to make mistakes, which often leads to a lack of accuracy. It is intended.

[Means for solving problems]

In view of such circumstances, the present invention provides a spool stop mechanism in a fishing reel depth storage device, a counting unit that counts the number of rotations of the spool through a sensor, a storage unit that stores the count value, and a line thread. The central processing unit that compares and processes the count value at the time of re-feeding and the stored value and outputs a predetermined drive motor control signal, the motor control unit that rotates the drive motor by a certain amount by the signal, and the drive motor The clutch shaft is constituted by the spool and the auto-return type clutch mechanism which is automatically returned to the meshed state by the rotation start of the drive shaft.

[Action]

The spool stop mechanism of the present invention according to the above configuration counts the number of rotations of the spool via the sensor when winding the road yarn,
This is stored in the storage unit, and when the line yarn is reeled out again, the central processing unit compares the count value of the free rotation of the spool with the stored value, and the motor control signal output when both numerical values match The drive shaft rotates the drive motor by an amount capable of automatically returning the clutch shaft, the clutch shaft meshes with the spool, and the free rotation is stopped.

〔Example〕

Hereinafter, the spool stop mechanism of the present invention will be described more specifically based on an embodiment shown in the drawings.

(No. 1) FIG. 1 shows an embodiment of an electric reel. In FIG. 1, 1 is a drive motor for winding a road thread, which rotates a drive shaft 4 via a reduction gear group 2 and a connecting gear 3. Reference numeral 5 is a master gear which is adapted to rotate together with the drive shaft 4 via a multi-disc clutch 7 pinched by a drag lever 6 and which rotates the drag lever 6 to apply a pressure contact force to the multi-disc clutch 7. By adjusting, the rotational torque of the spool 8 rotating via the clutch mechanism described below can be controlled.

Next, 9 operates the clutch lever 10 to elastically slide the clutch shaft 11 in the axial direction so that the spool 8 can be switched to a free or occlusal state and operates in conjunction with the rotation of the drive shaft 4. This is a so-called auto-return type clutch mechanism that automatically returns to the occlusal state instantaneously by a releasing mechanism 12 that is engaged with the master gear 5 by a clutch pinion 13.

Next, as shown in FIG. 2, a microcomputer 14 is provided with a counting unit 16 for counting the number of rotations of the spool 8, that is, the winding amount or the unwinding amount of the road yarn, through a sensor 15, and a counting unit 16. A storage unit 17 for storing numerical values, a central processing unit 18 for comparing and processing the count value and the above-mentioned stored value at the time of re-feeding of the road thread, and outputting a predetermined motor drive signal, and a constant amount of the drive motor 1 according to the signal. Rotating motor control unit 19
And the like.

Further, 20 is a control panel provided with operation buttons 20 'and the like, and 21 is a power source such as a storage battery.

Of course, the microcomputer 14 can also be used for automatic shift control of the drive motor at the time of winding the yarn, which is adopted in a normal electric reel, and automatic crimp control. Further, as the sensor for detecting the number of rotations of the spool 8, any sensor such as a non-contact type using a photoelectric element or a Hall element or a contact type can be selected.

Then, when fishing, I wait for Uoshinobu while crimping around the fish rack, but when I wind up the line with fishin, I started pressing the operation button 20 'in advance to start counting.
A normal winding operation is performed by the drive motor 1, and the number of rotations of the spool at the end of winding (the winding length of the road yarn) is stored in the storage unit 17.

Next, when setting the thread to the depth of the fish rack where the above-mentioned fishery was again, the spool 8 is set to the free state by the clutch lever 10 and the thread is fed out, and the number of rotations at that time is counted, and the previously stored numerical value is stored. Then, the central processing unit 18 outputs a predetermined drive motor control signal, and the motor control unit 19 receives the signal,
Drive shaft 4 is an automatic return type clutch release mechanism
Rotate the drive motor 1 just enough to activate 12,
The projection 12a of the release mechanism pushes the guide plate 12b to open the lift plate 11a of the clutch shaft, and the clutch shaft 11 elastically automatically returns to engage with the spool 8 to stop the rotation of the spool. .

(No. 2) FIG. 3 shows another embodiment of the present invention, in which a conventional manual reel equipped with an auto-return type clutch mechanism and a drive motor 1 controlled by the microcomputer or the like.
The reduction gear mechanism 22, the drive shaft 23 and the coupling gear 3
Although it is a fishing reel of a manual / electric combined type that is interlocked via a drive shaft 4, a drive shaft 4 rotates a spool 8 via a master gear 5 equipped with a multi-plate clutch 7 and an auto-return type clutch mechanism 9. Is equivalent to the first embodiment, and the handle 24 attached to one end of the drive shaft 4 allows the drive shaft 4 to be rotated at the time of manual operation by a one-way mechanism 25 composed of, for example, a ratchet. The drive motor 4 is designed so as not to rotate together with the drive shaft 4 when the drive motor is operated.

Further, the speed reduction mechanism 22 is connected to the drive shaft 23 with a roller clutch 26 interposed at the end thereof, as shown in FIG. 4, and the rotational force of the drive motor 1 is reduced by the action of the roller clutch. The torque is transmitted to the drive shaft 4, but the rotational force of the drive shaft due to the rotation of the handle during manual operation is prevented from being transmitted to the drive motor 1 side.

When re-feeding the yarn, the drive motor 1 is rotated by a certain amount in response to a signal processed by the microcomputer 14 and the spool is rotated via the auto-return type clutch mechanism 9 as in the first embodiment. It can be automatically stopped.

〔The invention's effect〕

As described above, the spool stop mechanism in the depth storage device for a fishing reel of the present invention, when the road thread reaches the storage depth, normally, by rotating the drive motor used for winding a fixed amount, Since the auto-return type clutch mechanism is activated to stop the free rotation of the spool, there is no need to provide an additional mechanism that combines parts such as solenoids and cams as in the conventional system, and the structure is extremely simple. In addition to the above, it is possible to expect a particular effect that the entire reel can be made smaller and lighter.

Further, since the spool stop mechanism according to the present invention uses an auto-return type clutch mechanism that is generally equipped on a manual reel, the rotation of the spool is stopped. It is expected that various effects can be expected, such as the combination of is extremely easy and can be performed with a simple configuration.
