Description

[Detailed Description of the Invention] The present invention involves applying separate first twists to a plurality of twisted threads stretched in parallel, and then twisting the first twists in the opposite direction to the first twist to entangle them. The handicraft twisting machine allows you to freely select the direction of the first twist and final twist by simply operating a control knob that moves between two positions. It is an object of the present invention to provide a handicraft twisting machine that can easily select the production of a fully twisted twisted string by simply operating an operating knob.

A preferred embodiment of the invention is illustrated in the accompanying drawings.

Fixed to.

Between the rear wall portion 2 of the mounting case 1 and the partition wall portion γ of the intermediate case 6, two rear saw gears are fitted onto the tubular shaft 3 and fixed to the rear wall portion 2, that is, the mounting case 1, with pins or the like. 23a, 23
b.

The teeth 24a and 24b of these saw gears have different protruding directions, and the teeth 24a of the rear saw gear 23a have an engagement surface facing left, and the teeth 24b of the rear saw gear 23b. has a right-facing engagement surface.

In addition, the partition wall portion 7 of the intermediate case 6 and the internal gear 16
and the back plate 11 are provided two front saw gears 25a and 25b which are fitted into the boss 18 and fixed to the back plate 17, ie, the internal gear 16, with a pin or the like.

These saw gears have teeth 26 a + 26 b in different protruding directions, the teeth 26 a of the front saw gear 25 a having an engagement surface facing left, and the teeth 26 b of the front saw gear 25 b having a leftward engaging surface. It has a right-facing engagement surface.

a rear parallel shaft 11a provided in the partition wall-like portion 7 of the intermediate case 6;
11b projects on both left and right sides of the rear saw gears 23a, 23b, and the front parallel shaft 12ati2b projects on the left and right sides of the rear saw gears 23a, 23b.
The parallel shaft 11at protrudes from both left and right sides of b.
llb and the parallel shafts 12a and 12b, respectively, have locking claws 28a,
28b and 30a, 30bQ shaft fit.

The stop pawl 28a corresponds to the rear saw gear 23a, the stop pawl 28b corresponds to the rear saw gear 23b, and the stop pawl 30a corresponds to the front saw gear 2.
5a, and the retaining pawl 30b corresponds to the front saw gear 25b, and the retaining pieces 29a, 29b engage with the teeth 24a, 24b, 26at26b of the respective saw gears when they are pressed by the spring 32. , 31a, and 31b are provided.

The retaining claws 28 a , 28 b and 30 ay 30 b form a pair and protrude to both sides of the notch 8 .

The notch 8 has two positions S on the left and right against the inner circumference of the intermediate case 6.
, Z is provided, and the protruding leg 35 of the operating knob 34 protruding from the outer periphery of the intermediate gear 76 is inserted through the pressing piece 33 and fixed by a threaded rod 36.

A retaining pawl 28 is attached to the pressing piece 33 using the first device Z shown in FIGS. 3 and 4.
a.

Pressing portions 3γa and 38a for pressing 30a, and pressing portions 37b and 38b for pressing pawls 28b and 30b by the second device S are provided.

39 is a leaf spring inserted between the operating knob 34 and the outer periphery of the intermediate case 6.

The pressing piece 33 is provided with a temporary locking portion 40 that prevents it from moving accidentally from either of the two positions S and Z.

In this embodiment, the operating knob 34 is
When moving to the device Z, the pressing piece 33 engages the retaining claw 28a,
30a is pushed against the elasticity of the spring 32, the stop pawl 28a is disengaged from the rear saw gear 23a, and the stop pawl 30a is disengaged from the front saw gear 25a.

Therefore, when the rotary shaft 21 with a needle is rotated counterclockwise in FIGS. 3 and 4, the internal gear 16 and the front saw gear 25b rotate counterclockwise in conjunction with each other, and at that time, the front saw gear 25b stops. The pawl 30b slides on the locking piece 31b and rotates without any trouble, but the pawl 28b, which is attached to the intermediate case 6 in the same way as the pawl 30b, cannot rotate by engaging with the rear saw gear 23b. Therefore, rotation of the intermediate case 6 and the front case 13 is prohibited.

Thus, the internal gear 16 causes the planetary gear 19 and the hook 20 to rotate counterclockwise.

Furthermore, when the rotating shaft 21, internal gear 16, and front saw gear 25b are switched to rotate clockwise, the stop pawl 30b engaged with the front saw gear 25b rotates clockwise together with the intermediate case 6, and the other stop The pawl 28b slides and rotates around the rear saw gear 23b.

Therefore, the front case 13 also rotates clockwise together with the internal gear 16 and the intermediate gear 76, and the internal gear 16 becomes stopped relative to the front case 13.

Therefore, the planetary gear 19 and the hook 20 revolve clockwise without any rotation.

When the operation knob 34 is set to the second device S and the locking pawls 28b and 30b are pushed by the pressing action piece 33 to disengage them from the corresponding rear saw gear 23a and front saw gear 25&, the rotating shaft with the nozzle is released. 210 clockwise rotation internal gear 16
The planetary gear 19 and the hook 20 are rotated clockwise in conjunction with each other.

When the rotating shaft 21 is switched to rotate counterclockwise, the internal gear 16, the intermediate case 6, and the front case 13 each rotate counterclockwise, causing the planetary gear 19 and the hook 20 to revolve counterclockwise. .

That is, depending on whether the operating knob 34 is moved to the first device Z or the second device S, the relationship between the rotation and revolution of the hook 20 becomes completely opposite.

As shown in FIG. 6, the handicraft twisting machine of the present invention has several twisted thread threads 52, 53, 54, such as woolen threads, arranged in parallel between a thread hook 51 fixed to a desk or the like and each hook 20. When the rotation shaft 21 with the bundle is rotated counterclockwise with the operating knob 34 set to the first position 2, each thread is twisted in the S direction due to the rotation of the hook 20, and the rotation shaft When the rotation of the hook 21 is switched to the clockwise direction, a Z-twisted string can be produced as shown in the figure by the revolution of the hook 20.

. Further, when the knob 34 is set to the second device S and the rotation shaft 21 with bundle is rotated clockwise, the rotation of the hook 20 causes a first twist in the Z direction to occur in each thread, and here the rotation shaft is switched to rotate clockwise. By rotating the hook 20, it is possible to produce an S-twisted string.

As clarified by the above explanations, the present invention enables selection of S-twisted and Z-twisted cords with opposite twisting directions by simply moving the operating knob from the first device Z to the second device S. It has a profit that can be made on a regular basis.
