Description

DETAILED DESCRIPTION OF THE INVENTION Generally, there are two methods for tying a fishing line to a fishhook: the main knot method and the outer knot method, in which the fishing line is wound around the fishhook several times (5 to 6 times), and the end of the fishing line is pulled and tightened. The present invention is an electric needle tying machine that uses a motor to rotate the fishing line to wind the fishing line around the fishing hook several times.The present invention incorporates an electronic control circuit that electrically detects the number of windings and automatically stops the winding. This is an attempt to make it simple.

With an electric needle knotter, the winding speed is fast,
If the fishing line is wound too much, the aligned winding will collapse, resulting in problems such as a decrease in the strength of the knot and the fishing line getting caught in the rotating part. The present invention provides an electric needle tying device which eliminates the above-mentioned inconvenience by allowing the number of windings of the fishing line to be set in advance, and which allows reliable tying with simple operation.

In FIG. 3, 25 is a needle set button, which is exposed on the outer surface, and a lever 26 is fixed to the inside. The lever 26 is an elongated metal plate and is rotatably attached to the inside of the cover 1 with a stud 27. The distal end thereof has a claw 26a which is tapered and bent into a V-shape. This pawl 26a is located at a position corresponding to the center of the bearing 14 of the case 2, and the cover 1 is cut into a right-angled shape around this part, and one end surface 28 of the pawl 26a corresponds to and parallel to the groove 14c of the case 2. positioned. The side end surface of the claw 26a of the lever 26 is connected to the cover 1.
It is in a straight line with the other end surface 29 of the right-angled portion,
When the needle set button 25 is lowered, the lever 2
6 rotates, and a gap is created between the claw 26a and the other end surface 29 of the cover, and the fishhook 13 is held in this gap. At this time, a spring 30 is applied so that the lever 26 returns to its original position.
is energized.

A sensor 31 (generally a detector) made of a reflective photocoupler is provided near the gear 6, and is placed on the top of a reflector 32 attached to the gear 6. When the gear 6 rotates, the sensor 31 (generally a detector) One pulse is generated. In this case, the parts of the gear 6 other than the reflecting plate 32 are painted black so as to absorb light. Detection can also be achieved by using a Hall element or reed switch as the sensor 31 and using a magnet instead of the reflecting plate 32.

Next, the configuration of the electronic circuit will be explained with reference to FIG. In the figure, reference numeral 19b is a contact point of the micro switch 19, which opens and closes the power supply circuit. A waveform shaping circuit 33 is a circuit that shapes the waveform of the output pulse of the sensor 31. The output of the waveform shaping circuit 33 is added to the input of the shift register 34. In the shift register 34, output terminal No. 1 is turned on with one pulse, No. 2 terminal is turned on with two pulses, and each terminal is turned on in sequence according to the number of input pulses. Each output terminal of the shift register 34 is
It is connected to the slide switch 21 in FIG. 2 and to the input terminal of the inverting amplifier circuit 35. The inverting amplifier circuit 35 is a circuit whose output is turned off when the input is turned on, and a relay 36 is connected to its output end. The normally open contact 36a of the relay 36 operates the electromagnet 9 and motor 4 shown in FIG. 2, and the normally closed contact 36b is connected to short-circuit the motor 4 and brake it. Another normally open contact 36c of the relay 36 is connected to both ends of the switch 19b to form a holding circuit.

37 is a pulse generation circuit for resetting the shift register 34 so that it always operates from the No. 1 terminal.This circuit generates one pulse when the switch 19b is turned on, and its output is sent to the reset terminal of the shift register 34. Connected to R.

In the above configuration, the operation of tying the fishing line to the fishhook will be explained next.

Lower the needle set button 25, rotate the lever 26, clamp the fishhook 13 between the claw 26a and the end face 29 of the cover 1, and at the same time insert the end 13a of the fishhook 13 into the square hole 12b in the center of the presser plate 12. . Next, as shown in FIG. 5, connect the tip of the fishing line 38 to the gear 6
The original fishing line 38 on the opposite side is inserted into the groove 14c of the case 2,
Pass through the groove 6a of the gear 6 and the groove 12 of the final holding plate 12.
Pass it through a and take it out to the back of case 2. and fishing line 3
8 below the product, hang it on the thread hook slider 16, and bring it out onto the surface of the cover 1. Next, wind the fishing line 38 above the product again in each groove 14c, 6a, 12a.
Pass it through and take it out to the back of case 2. At this time fishing line 38
is the spring 15 inserted into the square hole 14a of the bearing 14.
is held by. In this way, the fishing line 38 is set as shown in FIG. Next, when the switch button 18 is lowered, the button 19a of the micro switch 19 is pressed by the tapered portion 18b at the tip of the arm 18a, and the switch 19b is turned on. When the switch 19b is turned on, the pulse generation circuit 37 generates one pulse, resets the shift register 34, and resets the inverting amplifier circuit 3.
Since input 5 is off, the output is on,
The relay 36 operates, its contact 36a closes, the electromagnet 9 is energized, the stopper 7 and the annular projection 8 are disengaged, and the motor 4 rotates. Also, the sensor 31
When the switch 18b is turned on, a pulse is generated by the reflection plate 32, and the shift register 34
The No. 1 terminal will be turned on, and the process will start from this point.

When the motor 4 operates and rotates, the gear 6 rotates, and the fishing line 38 held by the line presser spring A10 is wound around the fishhook 13, and when the gear 6 rotates once due to the reflection plate 32, one pulse is generated. .
Now, if gear 6 rotates 5 times, sensor 31
There are 5 pulses, and 1 pulse at the start time, making a total of 6 pulses, so the pulse at the start time is bypassed with a capacitor, etc., and the output is made into 5 pulses. Therefore, the shift register 34
Since the output terminal of the terminal No. 5 is turned on, the knob 21a of the slide switch 21 is turned on to the terminal No. 5.
When the input is turned on and the output is turned off, the relay 36 is turned off and the contacts 36a and 3
6c opens, the motor 4 stops, and the electromagnet 9
is released, the stopper 7 engages with the notch 8a of the annular projection 8 of the gear 6, and the gear 6 is stopped at a fixed position. The fishing line 38 is now wound around the fishing hook 13 as shown in FIG. Next, the threading slider 16 is moved along the groove 17a of the side wall 17 of the case 2 in the direction of the groove 14c. Then case 2
Tighten the fishing line 38 that comes out on the back side of the
When the fishhook 13 is taken out, the knot is completed as shown in FIG.

In the above description, normally open contact 3 of relay 36
6c is for the holding function of the switch 19b, so there is no effect even if the switch 19b is released midway. In addition, the knob 21a of the slide switch 21 is exposed on the surface of the cover 1 and can be switched by external operation, so the normal number of knots is about 5 to 10.
Connect output terminals No. 5 to No. 10 of the shift register 34 to the slide switch 21, and attach a number near the square hole 1a of the cover 1 at the position of the knob 21a corresponding to this No. terminal. By moving the knob 21a to obtain the desired number of knots, it is possible to tie the desired number of knots with a simple operation.

Also, a binary counter and a NAND circuit can be used instead of the shift register 34. Moreover, the relay 36 can also be replaced with a transistor.

As described above, according to the present invention, the number of times the fishing line 38 is tied can be automatically detected by an electronic circuit, and the device can be stopped when a predetermined number of times has been reached. Not only can you tie knots, but you can also safely tie knots without the fishing line getting caught or coming loose. Furthermore, the number of knots can be easily changed by operating the knob 21a using the slide switch 21.
This has the advantage that the number of windings can be changed to a desired number depending on the size of the fishing hook 13 and the thickness of the fishing line.
