Abstract

PURPOSE:To measure the length of a line with high accuracy irrespective of thickness of the line by calculating a prescribed line length calculating expression by inputting an actual speed of revolution of a spool at the time of feeding/winding the line, which is counted by a counter and deriving the length of the line. CONSTITUTION:When a program is started, first of all, a CPU 10 decides whether a line is fed or not. When it has been decided to be fed, a spool 2 is rotated in the forward turn direction by following up the feeding of a fishing line 3, therefore, from a sensor 16, a signal in the forward turn direction is inputted to the CPU 10 through an input interface 13. As a result, a pulse signal of every one rotation of the spool is inputted to an up/down counter 17 and brought to up-count successively. Subsequent ly, at every operation period of a microcomputer 9, the counting contents of the count er 17 are inputted to the CPU 10, a line length operation of a line length calculating expression determined by the wound line diameter to a shape prescribed wound diame ter level of the spool and the total speed of revolution of the spool is executed, its result is outputted to an indicator 5, and the feed line length of the fishing line 3 is displayed on a display part 5a. In the case of winding, as well, the line length is obtained by almost the same procedure.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fishing reel line length measuring device, more specifically, a line length measuring device that can measure the amount of fishing line being fed out and wound up from the rotational speed of the spool. Regarding equipment.

[Conventional technology]

With modern fishing reels, by measuring the length of the fishing line from the spool or the length of the line being wound onto the spool, it is possible to accurately lower the tackle to the shelf where the fish are, or for cast fishing. It is now possible to display the flight distance to the point of the device.

Conventionally, as a method for measuring the amount of fishing line being fed out and taken up, the rotation of the spool is detected by a sensor, and the sensor detects the rotation of the spool for each rotation of the spool. The generated pulse signals are counted by a counter, and the counted value is taken into a microcomputer every calculation cycle to calculate the yarn length, and the calculated value is output to the display section to display the yarn length.

[Problem to be solved by the invention]

However, in the conventional yarn length measuring device as described above, the diameter of the yarn wound around the spool increases slightly as the yarn is unwound, and increases as the yarn is wound up. The length or winding length varies depending on the winding diameter of the thread. Therefore, count the number of pulses obtained for each rotation of the spool and calculate the number of pulses as 1. '7. Simply multiplying the yarn length per revolution of the pool does not measure the true yarn length, and there is a large error between the measured value and the actual length of the yarn being fed or wound. If the thickness of the thread used changes, the rate of change in the diameter of the thread during unwinding or winding also changes; 1, there is a problem in that the true length of the thread cannot be measured.

The present invention solves the above-mentioned conventional problems, and makes it possible to measure the thread length with extremely small errors by simply counting and inputting the rotational haircut count of the spool, regardless of the thickness of the system being used. The purpose of the present invention is to provide a fishing reel line length measuring device.

[Means to solve the problem]

The fishing reel line length measuring device according to the present invention includes a reel body, a spool that is rotatably supported by the reel body and around which a fishing line is wound, a sensor that detects the rotation of the spool, and a spool that is rotatably supported by the reel body and around which a fishing line is wound. The up/down counter counts up and down the output pulse signal, and the up/'down counter counts the total number of rotations when the fishing line is wound up to the specified winding diameter level on the spool. a means for capturing and storing numerical values, a line diameter determined up to the shape prescribed winding diameter level of the spool and a total number of rotations of the spool, and feeding out of the fishing line;
Or, it is equipped with a means for calculating the yarn length based on the actual number of revolutions of the spool rotated during winding, and a display for displaying the yarn length calculated by this calculating means. ] In the present invention, the line length calculation formula determined by the total number of revolutions of the spool, the specified winding diameter of the spool, and the shape of the spool when the fishing line is wound up to the specified winding diameter of the spool is calculated using an up/down counter. The yarn length is measured by taking in the actual number of rotations of the spool during yarn unwinding or yarn winding, which is counted in
Highly accurate yarn length measurement is possible regardless of the thickness of the yarn.

Further, 19 is a battery power source for operating the microcomputer 9 and the display 5.

Next, FIG. 3 will be explained.

Figure 3 is for explaining the relationship between the number of revolutions of the spool 2 and the outer diameter and length of the fishing line 3 wound on the spool 2 when the spool 2 is a straight type in which the winding width l does not change. It is.

In the figure, D: Diameter Do of the winding line at the specified winding diameter level of the fishing line 3 Bottom diameter of the Nisbourg 2 H: Depth of the spool 2 up to the specified winding diameter level Dl: Winding line displaced by one winding of the fishing line Outer diameter N: Total number of revolutions of the spool 2 when the fishing line 3 is wound onto the spool 2 to the specified winding diameter level H, N: Actual number of revolutions of the spool 2 when it is rotated by letting out or winding the fishing line 3 It is.

Here, if the spool 2 rotates N1 and the diameter of the winding thread changes from D to D, then the length of the thread to be paid out at this time is L = -N, " + b N, ... ( 1
) However, a: a constant regarding H, b=a constant regarding D.

In the above yarn length calculation formula, D and H are constants determined in advance according to the spool shape, N is a constant determined according to the yarn type, and N is a variable that changes as the spool 2 rotates.

Therefore, the formula (1) above is stored in ROMII,
By executing this equation (1), it is possible to measure the length of the delivered yarn or the length of the wound yarn depending on the rotational speed N of the spool 2.

Next, the operation of this embodiment will be explained with reference to the flowcharts of FIGS. 4 to 6.

First, the bottom diameter. The case of inputting the total number of revolutions of the spool 2 when the thread is wound on the spool from D to D will be explained according to the procedure shown in FIG.

First, with the battery power source 19 connected to the microcomputer 9, the microcomputer 9 is initialized and placed in a starting state.

When the mode changeover switch 6 is pressed in this state (step S1), the microcomputer 9 is set to the spool total rotation number input mode, and the display section 5 of the display 5 is inputting.''
is lit (step S2).

Next, tie one end of the fishing line 3 to the bottom diameter of the spool 2,
Rotate the handle 8 to rotate the spool 2 and remove the fishing line 3.
are sequentially wound onto spool 2. At this time, a line guide of a level winder mechanism (not shown) traverses in the width direction of the spool 2 in synchronization with the rotation of the spool 2, so that the fishing line 3 is wound around the spool at a uniform winding level and with a uniform density.

On the other hand, when the spool 2 rotates in the line winding direction, the up/down counter 17 is set to up count, and the pulse signal for each rotation of the spool output from the sensor 16 is sent to the up/down counter through the input interface 13. 17 and sequentially incremented (step 33). In the next step S4,
When the count value of the up/down counter 17 reaches a predetermined count value, for example, 500 or more, the "input in progress" display blinks to notify that the total number of rotations is being counted.

Spool 2 until the fishing line 3 reaches the specified winding level diameter of spool 2.
When the fishing line has been wound up, the fishing line winding operation is stopped and the data writing switch 7 is pressed in the next step S5. Then, the count value of up/down counter 17 becomes spool 2.
is stored in the RAM 12 as the total number of rotations N, and is "inputting"
disappears, and the microcomputer 9 is set to display mode. At this time, the display section 5a of the display device 5 is displaying "0".

Next, the yarn length measuring operation will be explained according to the processing procedure shown in FIG.

When the program shown in FIG. 5 starts, first, in step SIO, it is determined whether or not the thread is to be let out. Here, if it is determined that the fishing line 3 is being fed out, the spool 2 is rotated in the normal direction as the fishing line 3 is being fed out, so a signal in the normal rotation direction is sent from the sensor 16 to the CPU10 through the input interface 13. This sets the up/down counter 17 in the up direction, and the pulse signal for each spool rotation output from the sensor 16 as the spool rotates 20 times is input to the up/down counter 17 through the input interface 13. are sequentially counted up (step 311).

In the next step S12, the count content N1 of the up/down counter 17 is calculated every calculation cycle of the microcomputer 9.
is loaded into the CPU 10, the line length calculation in (1) 2 is executed, the calculation result is output to the display unit 5 through the output interface 14 and the decoder 18, and the length of the fishing line 3 to be paid out is digitally displayed on the display unit 5a. (Step 51
3).

On the other hand, if it is determined in step SIO that the fishing line is being wound up, the spool 2 is
is rotated in the reverse direction, a reverse direction signal is sent from the sensor 16 to the CPU through the input interface 13.
0, which causes the up/down counter 1
7 is set in the down direction, the pulse signal output from the sensor 16 as the spool 2 rotates in the opposite direction is captured by the up/down counter 17, and is subtracted from the count counted at the time of feeding by its down-counting operation (
step 314). Then, in the next step S15,
The count contents N of the up/down counter 17 are taken into the CPU10 every calculation cycle of the microcomputer 9,
By executing equation (1), the winding yarn length, that is, the yarn length obtained by subtracting the winding yarn length from the unreeled yarn length, is calculated, and this is output to the display 5 to display the yarn length. 5a (step 316).

FIG. 7 is a graph showing the relationship between the number of revolutions N1 and the yarn length, where calculated values are shown as a solid line, and actual values are shown as black dots. As is clear from this graph, it was confirmed that the error between the measured value and the calculated value was extremely small, within 0.3%.

Next, a case will be described in which the total number of revolutions due to yarn breakage is corrected.

In this case, as shown in FIG. 6, first, the handle 8 is rotated to wind the thread onto the spool 2 until the end of the thread is just in front of the reel body 1 or at the tip of the rod (step 20). Then, in the next step S21, the mode changeover switch 6 is pressed to set the microcomputer 9 to the correction mode. At this time, the display "correction" on the display section 5c of the display device 5 flashes.

After the microcomputer 9 is set to modification mode,
In the stub 322, when the data write switch 7 is pressed, the remaining count value N set in the up/down counter 17, (the number of rotations of the spool 2 by winding up the thread from the number of rotations of the spool counted at the time of feeding to the end of the broken thread) ) is stored in the RAM 12, and this remaining count value N is added to the number of rotations N counted by the up/down counter 17 thereafter to calculate the yarn length. Then, by pressing the switch 7, the correction of the count value due to thread breakage is completed, and the display returns to the original display mode.

In addition, Figure 6 shows the time when the thread is being fed out, and the time when the thread is being wound is N.
, subtract.

I have explained about the straight type spool above, but the winding width of spool 2! In a taper spool where the diameter changes, the bottom diameter shown in Figure 3. Since the winding width of and the winding width of the specified winding diameter are different, with these winding diameter widths as constants, D
, H, the yarn length in the tapered spool can also be measured with high accuracy.

In addition, each constant in the yarn length calculation formula changes depending on the shape of the spool 2, so constants corresponding to various spools 2 are stored in ROMII in advance, and the spool 2 incorporated in the reel body 1 is stored in the ROM II in advance. The spool data in the ROMII may be selectively set depending on the situation.

〔Effect of the invention〕

As described above, according to the present invention, constants determined according to the shape of the spool are set, and these constants and the total number of revolutions of the spool when the fishing line is wound up to the specified level of the spool are set. The line length can be measured by calculating the line length calculation formula based on the actual number of rotations of the spool at the time of winding the line. In addition to being able to measure the thread length with high precision, the only data input required is the total number of rotations of the spool when the thread is wound to the specified winding diameter of the spool, and the data input operation is also easy. Since this is possible with a one-touch operation of the data write switch, the data input operation is simple, and since the type of thread is not limited and can be used with any thread type, it can be used in a wide range of fishing conditions and is highly practical. There is a certain effect.
