Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a needle tying device for tying a fishing line to a fishhook, and the thread winding mechanism is automatically stopped when the fishing line has been wound around the fishhook a certain number of times, thereby simplifying the operation of the needle tying device. The purpose is to measure the

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external front view of the needle tying device of the present invention, FIG. 2 is a front view showing the internal mechanism with the cover removed, and FIGS. 3 and 4 show the configuration of the main parts thereof. In these figures, 1 is a cover, 2 is a case, and 3 is a battery case.A motor 4 is attached to the case 2, and a gear 5 is press-fitted to the shaft of the motor 4, and this gear 5 forms a main rotating plate. Gear 6 is meshed. The main rotary plate 6 has a donut shape,
A disk-shaped presser plate 7 fixed to the case 2 is fitted into the center hole and rotatably attached to the case 2, and a fishing line (not shown) is held by a spring 8 fixed to the upper surface with a screw. , a fishing line is wound around a fishhook attached to the center portion 7a of the presser plate 7.
A gear 9 is further engaged with the main rotary plate 6, and an arm 11 of a planetary gear 10 of a planetary gear apparatus in which the gear 9 is a sun gear is held in the case 2. A notch 13 is provided in a part of the outer periphery of the internal gear 12 which serves as a driven rotary plate of this planetary gear device.
A claw 15 at one end of a switch lever 14 is removably engaged with the switch lever 3. The switch lever 14 has an operation button 16, and a tapered portion 17 at the other end is a micro switch 1 that opens and closes the drive circuit of the motor 4.
8, and the spring 20 constantly pushes the pawl 15 in the direction of the internal gear 12.

Now, to explain the case where the fishing line is wound around the fishhook five times and automatically stopped when the winding is finished, the number of teeth of gear 6 is 50, and the number of teeth of gear 9 that meshes with gear 6 is
10 and the reduction ratio of the planetary gear device is 1/25,
The reduction ratio of gear 6 and the planetary gear device is 50/10 x 1/25 = 1/
5, and when the gear 6 rotates five times, the internal gear 12 of the planetary gear device rotates once.

Next, its operation will be explained. As shown in FIG. 3, when the operation button 16 of the switch lever 14 is lowered, the pawl 15 comes off from the notch 13 of the internal gear 12, and at the same time the taper part 17 at the other end of the switch lever 14 opens the push button of the micro switch 18. 19 is pressed, the motor drive circuit is closed, the motor 4 rotates, and the gear 5, main rotating plate 6, gear 9, and internal gear 12 rotate. Even if you release your hand from the operation button 16 in this state, the pawl 15 of the switch lever 14 will not touch the internal gear 1.
2, the micro switch 18 remains pressed, the main rotary plate 6 and the internal gear 12 continue to rotate, and the fishing line is wound around the hook.

When the main rotating plate 6 approaches the end of the fifth rotation, the fourth
As shown in the figure, the notch 13 of the internal gear 12 approaches the end of the first rotation, and when the main rotary plate 6 completes five rotations, the internal gear 12 also completes one rotation, and the switch lever 14 is kept in position by the spring 20. Since it is pushed upward, the claw 15 of the switch lever 14 enters the notch 13 of the internal gear 12, the switch lever 14 rises upward, and the push button 19 of the micro switch 18, which was pressed by the taper part 17, returns to its original position. Then, the motor drive circuit opens and the motor and main rotating plate stop rotating. In this way, the main rotating plate 6
When the fishing line rotates five times, the fishing line is held by the spring 8 and the fishing line is wound around the fishing hook five times.

5 and 6 show other embodiments of the speed reduction mechanism. In these figures, 21 is an annular protrusion provided on the back surface of the main rotating plate 6, and one tooth 22 is provided in a part of the annular protrusion. 23 is this one tooth 22
It is a driven gear that meshes with the driven gear and rotates intermittently by a certain angle.A part of the driven gear is provided with an annular protrusion 24 and a notch 25, and the switch lever 14 is connected to the notch 25.
The claws 15 are configured to fit together. The driven gear 23 rotates by one tooth when the main rotary plate 6 rotates once, and in the illustrated embodiment, when the main rotary plate 6 rotates five times, the driven gear 23 rotates once and the pawl 15 rotates. The main rotary plate 6 stops rotating when it is fitted into the notch 25 .

In addition, a Geneva gear, a Maltese cross, etc. can also be used for the speed reduction mechanism.

As described above, according to the present invention, by appropriately setting the reduction ratio of the main rotary plate 6 and the driven gear of the reduction mechanism, it is possible to wrap an arbitrary number of threads around the needle, and just by pressing the switch, the thread can be wound around the needle. Since there is no need to count the number of windings, the operation is significantly simplified.
