Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fishing reel, and more specifically, the length of the fishing line unreeled from the spool is determined based on the amount of rotation of the winding system in which the fishing line is wound. It is related to technology for notifying.

[Conventional technology]

Conventionally, a technique configured as described above is disclosed in Japanese Patent Application Laid-open No. 1986-
In this conventional example, the diameter of the fishing line to be wound onto the spool is input in advance, and when the fishing line is paid out from the spool,
The length of the fishing line let out from the spool is determined by calculation based on data based on the diameter of the fishing line and the amount of rotation of the spool, and is output to the display section.

When winding fishing line onto a spool, the winding diameter of the spool also increases as the amount of winding increases. If the length of the fishing line that is paid out from the spool is determined based on the length of the fishing line that is paid out from the spool, it cannot cope with changes in the winding diameter, resulting in large errors, which is why the above-mentioned conventional technique has been proposed.

[Problem to be solved by the invention]

Now, considering fishing lines, the diameter of fishing lines in Japan is expressed in [number], but this
Currently, there is some variation in the diameter of fishing line depending on the manufacturer.

Therefore, when inputting the diameter of the fishing line for the conventional reel, if the diameter value is input based on the "number", an error will occur in the length of the fishing line that is reeled out, so it cannot be improved. There's room.

Also, considering the conventional example mentioned above, this conventional example is configured so that the change in the length of the fishing line corresponding to a predetermined amount of rotation of the spool when winding the fishing line onto the spool can be grasped by a function, and such a function is , are stored in advance in correspondence with a plurality of types of fishing lines having different diameters, so that when used, one of the functions is selected based on the diameter of the fishing line.

Furthermore, considering a double-bearing reel, since the line guide part of the level wind mechanism reciprocates in the horizontal direction and winds the fishing line onto the spool, the thread guide part of the level wind mechanism moves between the stroke ends at both ends. The winding diameter of the spool in the process of reciprocating by % remains a constant value.

Applying this to the situation when winding a fishing line onto a spool, the change in the winding amount (LX) corresponding to the rotation amount (X) of the spool is as shown in FIG.
The characteristic is a combination of a linear function that increases the slope for each number of revolutions (S) of the spool required for reciprocating movement.

On the other hand, in the conventional example described above, the function described above is expressed as a high-order function whose slope increases each time the rotational speed of the spool increases. contains errors, and there is room for improvement in terms of accuracy.

Incidentally, the same can be said of a spinning reel since the spool reciprocates in the front and back direction during winding.

SUMMARY OF THE INVENTION An object of the present invention is to rationally construct a fishing reel that can as accurately as possible determine the length of the fishing line reeled out from the spool based on the amount of rotation of the winding system.

[Means to solve the problem]

The features of the present invention are the amount of rotation of the winding system required to wind a predetermined length of fishing line onto a spool, and the operation in which the line guide section of the line leveling mechanism reciprocates by 1/2 between the stroke ends at both ends. In addition to measuring each number of times with a measuring means, using this measurement result and each value of the winding diameter at the start of winding the fishing line onto the spool, the line guide section measures the distance between the stroke ends of both ends by 1/ Based on the condition that the length of the line wound per rotation of the winding system during two reciprocating operations is regarded as a constant value, after the winding of the fishing line is completed, the amount of rotation of the winding system in the unwinding direction, or A restriction means that calculates the length of the fishing line let out from the spool corresponding to the amount of rotation in the winding direction of the winding system when the fishing line is wound onto the spool without rotating the spool, and outputs it to the notification device. The functions and effects are as follows.

[For production]

If the above characteristics are configured as shown in FIGS. 1 to 5, for example, when winding the fishing line (2) onto the spool (3), the line guide tool (4) of the line leveling mechanism (A) is used. Since the winding diameter is constant during the process of moving within the stroke ends at both ends, for example, the entire fishing line (2) of the set length (L) is rotated (Q) with respect to this spool (3). In the case of winding, the winding system rotation speed (R
, ) means that the number of layers of fishing line (2) is formed by the integer part (M) of the value of (Q) divided by The amount of change in the winding diameter at each time can be determined with high accuracy.

By determining the amount of change in the winding diameter for each layer with high accuracy, the fishing line (2) is transferred from the spool (3) to the fishing line (2).
When the is fed out, the amount of change, the amount of rotation of the winding system,
Furthermore, the length of the fishing line (2) let out from the spool (3) can be determined using a simple calculation formula.

The above operations are expressed as in the flowcharts of FIGS. 4 and 5, and another form of operation is expressed as in the flowcharts of FIGS. 6 and 7.

〔Effect of the invention〕

Therefore, a reel has been rationally constructed that not only eliminates the need to input the diameter when winding the fishing line, but also allows the length of the fishing line unwound from the spool to be determined with extremely high accuracy.

In particular, with the present invention, it is not necessary to input the value of the diameter of the fishing line, so even when using ``strand'', which is difficult to measure the diameter, it is possible to accurately determine the amount of reeling out. Even if this occurs, by setting the length and performing the winding operation again, the length of the fishing line let out from the spool can be determined with extremely high accuracy during use, as described above.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

) or the length of the fishing line (2) being let out from the spool (3) and displaying it in digital numbers on the liquid crystal display (lO) (hereinafter referred to as display mode). (2) To ensure accurate length display, attach any length of fishing line (2) to the fishing line (2) or the unwound spool (3).
The amount of rotation of the spool (3) required to wind up the

The amount of change in winding diameter (ΔD) is calculated based on the bottom diameter value (D3) in step 3) (this operation is hereinafter referred to as learning mode), and when the fishing line (2) is let out from the spool (3), teeth,
The length of the fishing line (2) is determined based on the amount of change in winding diameter (ΔD), etc. and the amount of rotation of the spool (3), and the display (10
) can be displayed.

That is, as shown in FIG. 4, the learning mode is started by turning on the reset switch (13), and after initial setting, the setting switch (If),

In addition, when setting the winding length (L) in this way, for example, if the length of fishing line (2) at the time of sale is clear from the description on the package, etc., you can set the value of that length. If the exact length is unknown, use a mechanical counter (17) with a pulley (16) around which the fishing line (2) is wound to measure the length in advance, as shown in Figure 1. All you have to do is prepare by measuring the value, etc., and when making this setting, use the pair of setting switches (11) and (11) to increase or decrease the value displayed on the display (10). It turns out.

Next, by winding the fishing line (2) onto the spool (3) by operating the handle (7), the Hall element (9) is wound.
) and (9), the rotation of the spool (3) is counted one rotation at a time, and this counting continues until the set switch (12) is turned on. ) is set to (Q) (steps #106 to #109).

The ON operation of this set switch (12) is

Further, the above-mentioned predetermined formula "rf(L,Q)" is established based on the following logic.

That is, as shown in Fig. 3, the bottom diameter of the spool is (D8), and the number of rotations of the spool (3) required for the thread guide (4) to move 1/2 back and forth is (R).
, #) respectively, and also set the length of the fishing line (2) wound on this reel as "L".
”, the spool required to complete this winding (3)
When the total number of rotations is set to "Q", only the winding layer or "MJ layer" of the fishing line (2) is formed on the spool (3), and there is an excess of winding by the amount of rotation (RM).
This rM'', (RM) is determined by the following formula.

M = INT(Q”R,) -old-----

3) It becomes possible to obtain a formula for determining the length (RN) of the fishing line (2) wound up.

In addition, rLJ and rRMNJ in formula (b) are formula (a).

These values represent the number of layers and excess winding determined based on (b).

For the above reasons, equation (f) corresponds to the function of step #110, and equation (g) corresponds to the function of step #111.

Next, when the learning mode ends as described above, the display mode automatically starts as shown in FIG. 5. In this display mode, after the initial setting, the spool (3) Every time (3) rotates once, the count value (
Decrement or increment N) (#
Steps 201 to #205).

Also, this count value holds the value (Q) when the fishing line (2) is wound around the spool (3), and
When the fishing line (2) is let out from the spool (3)
By decrementing the count value based on the rotation of By subtracting from the length (L), the feeding amount (LN
) is required (Step #206).

The value of (LN) is updated and displayed each time the fishing line (2) is let out from the spool (3), and this display is configured to continue until the reset switch (13) is turned on. (Steps #207 and #209).

In addition, in this display mode, consideration has been made to ensure that the display will not be distorted even if the fishing line (2) breaks, and if a break occurs, the current count can be changed by turning on the set switch (12). After setting the value (N) to (Q),
The display is set to “OJ” (#208,
#210. #211 step).

[Another example]

The present invention is not limited to the control operation described above, but is also applicable to FIGS. 6 and 7.
It is also possible to configure the device to operate as shown in the figure.

That is, when the learning mode starts, after winding the fishing line (2) (steps 6301 to #305), the winding length of the fishing line (2) is set (steps #306 to #30).
9 steps).

If the length of the fishing line (2) can be set after winding, for example, when relearning the length of the fishing line (2) that has been stretched due to long-term use, the length of the fishing line (2) can be set using the counter (17 ) can be used in combination, which eliminates the hassle of measuring the length in advance.

Next, calculate the amount of change in the winding diameter (ΔD) and use the formula 'RN=F (N
) After setting a constant to J, this formula rRs=F (NI

” value on the display (10) and exit (
#310 to #314 steps).

In this way, by creating map data that calculates the payout amount (LN) based on the count value (N) based on the point at which winding is completed, complicated calculations are not required when displaying the map data. , accurate values can be displayed quickly.

Next, when the display mode is entered, the rotation of the spool (3) is counted from #401 to
405 steps), this number of rotations (N) from the map data
The value (LN) corresponding to is read out and this value (LN) is displayed on the display (10) (steps #407 to #409).

In addition, when the fishing line (2) is cut in this display mode, after setting the lost length to constant (C), set the display to "0", and when the amount of feed is displayed, , the value of this constant (C) is reduced (steps #408, #410 and #411).

Furthermore, the present invention may perform operations other than those shown in the flowchart, the notification means may be a PCM sound source, etc., to recognize the numerical value in human words, and the reel may be of an electric type. It may be.

Further, in the present invention, it is also possible to configure the measuring means by adding a switch, etc. that is turned on every time the level wind mechanism or the stroke end is reached.

Further, in the present invention, as shown in FIG. 9, the reel body (20
) is equipped with a spool (3) and a rotor (21) at the front of the reel body (20) during winding.
The rotor (21) is rotated by the rotation of the fishing line (2
), and in this other embodiment, the rotor (21) is equipped with a magnet (8), and the reel body (20) is equipped with a Hall element, etc. as a measuring means. By providing a sensor (9) and a counter case (5), the learning operation similar to the above-mentioned double bearing reel is performed based on the rotation of the rotor (21), and after discharging the workpiece, Fishing line (2)
Based on the amount of rotation of the rotor (21) required to complete the winding, that is, when the work is pulled to the hand,
It is also possible to display the distance to the thrown device on the display (10).

In addition, in this other embodiment, the numerical value is not displayed during the process of towing the device, and the distance can be displayed only when the towing is completed, so the control routine for display is further simplified. (control operations are not detailed).
