In addition, since there is no need to dispose a power transmitting member for driving the plurality of combustible devices in common, the size of the entire false-twist machine can be reduced. Further, since the mechanism for power transmission becomes compact, maintenance can be facilitated.

Further, in the present invention, since a plurality of the twisting devices are individually provided with the belt driving sources, it is possible to independently control the plurality of twisting devices.

And the power of the belt driving source is transmitted to the first connection pulley (and the first drive pulley) and the second connection pulley (and the second drive pulley) through the power transmission belt in opposite directions to each other. Whereby the first twister belt and the second twister belt are driven, and the first yarn is twisted by the first twister belt and the disc, and the second yarn is twisted in the opposite direction to the first yarn by the second twister belt and the disc. Therefore, it is not necessary to use a long belt for commonly driving a plurality of the twisting devices, and each twisting device can be driven by a belt having a size that fits within each of the twisting devices.

In the present invention, the outer surface of the belt is in contact with the inner surface of the belt to the auxiliary pulley, respectively. That is, the belt is wound in an S-shape or a Z-shape with respect to these pulleys. As a result, the belt can be wound around the second connection pulley at a large angle to increase the contact area between the belt and the second connection pulley, thereby suppressing slippage of the belt relative to the second connection pulley.

In the second or third aspect of the invention, a plurality of first teeth arranged in the belt longitudinal direction are formed on the inner surface of the power transmission belt, and the outer surface of the power transmission belt is provided with A plurality of first grooves for engaging with the plurality of first teeth on the inner surface of the power transmission belt are formed on the outer circumferential surface of the first connection pulley, A plurality of second grooves engaging with the plurality of second teeth on the outer surface of the power transmission belt are formed on the outer peripheral surface of the power transmission belt.

[ A plurality of grooves 66 (" second grooves " in the present invention) formed along the rotational axis direction of the pulley 65 are arranged at substantially equal intervals in the circumferential direction of the pulley 65 on the outer peripheral surface of the pulley 65 (See FIG. 5).

A pulley 67 (an "auxiliary pulley" of the present invention) is rotatably provided at a position opposite to the pulley 55 with the pulley 65 interposed therebetween in the expected longitudinal direction (see FIG. 5) . On the outer peripheral surface of the pulley 67, a plurality of grooves 68 formed along the rotational axis direction of the pulley 67 are arranged at substantially equal intervals in the circumferential direction of the pulley 67 (see Fig. 5).

The driving unit 34 is for driving the twister belt 53 and the twister belt 63 in common, and is separately provided in each of the twisting devices 15. As shown in Fig. 3, the driving unit 34 is disposed above the disk 31, for example. The drive unit 34 has a motor 71 (a "belt drive source" of the present invention) as a power source and a pulley 72 connected to the rotation axis of the motor 71. The rotary shaft of the motor 71 extends upward toward the working space 8 side. The pulley 72 is disposed above the motor 71 at an oblique angle. In other words, the motor 71 is disposed between the disk 31 and the pulley 72. On the outer peripheral surface of the pulley 72, a plurality of grooves 73 formed along the rotational axis direction of the pulley 72 are arranged at substantially equal intervals in the circumferential direction of the pulley 72 (see Fig. 5).

5, a belt 35 (a "power transmission belt" of the present invention) is wound around the pulleys 55, 65, 67, The belt 35 is an endless belt for transmitting the power of the drive unit 34 to the pulley 55 and the pulley 65. The inner surface of the belt 35 is in contact with the pulleys 55, 67 and 72 and the outer surface of the belt 35 is in contact with the pulley 65. 5, a plurality of teeth 75 (the "first tooth" of the present invention) and a plurality of teeth 76 (the "second tooth" of the present invention) are formed on the inner surface of the belt 35 And are arranged at substantially equal intervals in the longitudinal direction of the belt 35, respectively. A plurality of teeth 75 on the inner surface of the belt 35 are engaged with a plurality of grooves 56, 68 and 73 of the pulleys 55, 67 and 72 and a plurality of teeth 76 on the outer surface are engaged with the pulleys 65, (Not shown).

Next, the operation of the twisted device 15 having the above-described configuration will be described. First, as shown in Fig. 2, the disk 31 is rotationally driven in the direction of the arrow (clockwise direction in Fig. 2) by a motor not shown with the shaft 41 as the center.

Next, the operation of the belt unit 32 and the belt unit 33 will be described with reference to Figs. 2 and 5. Fig. 5, the pulley 72 connected to the motor 71 and the pulley 72 wound on the pulley 72 rotate in the predetermined direction (the counterclockwise direction in Fig. 5) The power of the motor 71 is transmitted to the pulley 55 of the belt unit 32, the pulley 65 of the belt unit 33 and the pulley 67 via the belt 35. [ Here, since the pulleys 55, 67, and 72 are all in contact with the inner surface of the belt 35, these pulleys rotate in the same direction (counterclockwise in Fig. 5). On the other hand, since the outer surface of the belt 35 is in contact with the pulley 65, the power of the motor 71 is transmitted in the opposite direction to the pulley 55 and the like. That is, the pulley 65 rotates in a direction opposite to the rotation direction of the pulley 55 or the like (clockwise direction in Fig. 5). Here, the teeth 75 of the belt 35 engage the grooves 56, 68, 73 of the pulleys 55, 67, 72 with the teeth 76, respectively, into the grooves 66 of the pulley 65, The slip of the belt 35 against the belt 55 is prevented.

When the pulleys 55 and 65 rotate as described above, the pulleys 51 and 61 rotate integrally with the pulleys 55 and 65, respectively. The pulley 51 and the pulley 61 rotate in opposite directions because the pulley 55 and the pulley 65 rotate in opposite directions as shown in Fig. As a result, power is transmitted to the twister belt 53 and the twister belt 63. Here, the portions of the twister belt 53 and the twister belt 63 closer to the disk 31 run in the same direction with respect to the disk 31, respectively. In addition, the pulleys 52 and 62 are rotated vertically by driving the twister belts 53 and 63, respectively.

The yarn Y1 is sandwiched by the ring portion 42 of the rotating disk 31 and the twister belt 53 traveling in this manner and the yarn Y1 is subjected to Z-folding. Further, the yarn Y2 is sandwiched by the ring portion 42 and the twister belt 63, and the yarn Y2 is subjected to S-shaped twist. That is, the yarn Y1 and the yarn Y2 are twisted in opposite directions to each other.

As described above, the plurality of twister devices 15 each include a motor 71 for driving the twister belt 53 for twisting the yarn Y1 and the twister belt 63 for twisting the yarn Y2. That is, each of the twisting devices 15 is independently driven by the individual motors 71. In this case, the sizes of the individual motors 71 are smaller than those in the case where the plurality of twister devices 15 are commonly driven by one motor, and noise and vibration generated by the motors 71 are significantly reduced, , And vibration can be reduced. In addition, since there is no need to dispose a power transmitting member for driving the plurality of twisting devices 15 in common, the size of the entire twisting machine 1 can be reduced. Further, since the mechanism for power transmission becomes compact, maintenance can be facilitated.

Further, since the plurality of the twisting devices 15 individually include the motors 71, the plurality of twisting devices 15 can be controlled independently. For example, when it is necessary to stop any one of the plurality of twisting devices 15 due to occurrence of yarn breakage or the like, simply by stopping the motor 71 of the twisting device 15, ) Stops. That is, even if there is no mechanism for separating the belt 35 and the pulleys 55, 65, each of the flammable devices 15 can be stopped individually, so that the structure of the flammable device 15 can be simplified. The speed at which the yarns Y1 and Y2 are twisted is different between the twisting devices 15 by making the running speed of the twister belts 53 and 63 different between the twisting devices 15 in accordance with the output of the motor 71 can do. Therefore, it is also possible to produce a plurality of kinds of yarns Y in the twisting machine 1. [

In each of the plurality of twisting devices 15, the inner surface of the belt 35 contacts the pulley 55, and the outer surface thereof contacts the pulley 65, respectively. The power of the motor 71 is transmitted to the pulley 55 (and the pulley 51) and the pulley 65 (and the pulley 62) through the belt 35 in the opposite directions. As a result, the twister belt 53 and the twister belt 63 are driven and the yarn Y1 is twisted by the twister belt 53 and the disc 31. The yarn Y1 is twisted by the twister belt 63 and the disc 31, Y2 are twisted in the direction opposite to the thread Y1. Therefore, each of the combustible devices 15 can be driven by the belt 35 of the size accommodated in each of the combustible devices 15, without using a long belt for commonly driving the plurality of combustible devices 15 .

The outer surface of the belt 35 and the inner surface of the belt 35 are in contact with the pulley 65 and the pulley 67, respectively. That is, the belt 35 is wound around the pulleys S-shaped or Z-shaped. This makes it possible to increase the winding angle of the belt 35 with respect to the pulley 65 to increase the contact area between the belt 35 and the pulley 65 and thereby suppress slippage of the belt 35 relative to the pulley 65 .

The teeth 75 formed on the belt 35 and the grooves 56 of the pulley 55 are engaged with each other so that the teeth 76 and the grooves 66 of the pulley 65 are engaged with each other. Therefore, the slip of the belt 35 against the pulleys 55 and 65 is prevented, and the power of the driving unit 34 is transmitted to the twister belt 53 and the twister belt 63 in a stable manner. Thus, the yarns Y1 and Y2 ) Is less likely to vary. Therefore, deterioration of the yarn quality can be suppressed. In addition, it is possible to suppress unevenness in yarn quality between the plurality of twisting devices 15. [
