Thereby, there is no need to use a long belt for driving a plurality of false twisting devices in common, and each false twisting device can be driven by a belt whose size can be stored in each false twisting device. [0012] The false twisting machine of the third invention is characterized in that in the second invention, an auxiliary pulley is arranged at a position opposite to the first connecting pulley with the second connecting pulley interposed therebetween. The power transmission belt is wound across the first connecting pulley, the second connecting pulley, and the auxiliary pulley, and the inner surface of the power transmission belt is in contact with the auxiliary pulley.　　[0013] In the present invention, the outer surface of the belt is in contact with the second connecting pulley, and the inner surface of the belt is in contact with the auxiliary pulley. That is, the belt is wound in an S-shape or a Z-shape with respect to these pulleys. Therefore, the winding angle of the belt with respect to the second connecting pulley can be increased, and the contact area between the belt and the second connecting pulley can be increased, so that the belt can be prevented from slipping with respect to the second connecting pulley. [0014] The false twisting machine of the fourth invention is characterized in that, in the second or third invention, a plurality of first teeth arranged in the belt length direction are formed on the inner surface of the power transmission belt, and A plurality of second teeth arranged in the belt length direction are formed on the outer surface of the power transmission belt, and the plurality of second teeth that are connected to the inner surface of the power transmission belt are formed on the outer peripheral surface of the first connecting pulley. A plurality of first grooves meshed with one tooth, and a plurality of second grooves meshed with the plurality of second teeth of the outer surface of the power transmission belt are formed on the outer peripheral surface of the second connecting pulley. [0015] In the present invention, the first teeth formed on the inner surface of the power transmission belt mesh with the first grooves formed on the first connecting pulley, and the second teeth formed on the outer surface of the power transmission belt mesh with The second groove formed on the second connecting pulley engages. Therefore, the power transmission belt is prevented from slipping with respect to the first and second connecting pulleys, and the power of the belt drive source is stably transmitted to the first twisting belt and the second twisting belt. Therefore, the number of twists per unit length of the yarn is difficult. change. This can suppress the deterioration of the yarn quality. In addition, it is possible to suppress variations in yarn quality among a plurality of false twisting devices.

[0045] In addition, a pulley 67 ("auxiliary pulley" of the present invention) is rotatably provided at a position opposite to the pulley 55 via the pulley 65 in the longitudinal direction of the machine (refer to FIG. 5). ). On the outer peripheral surface of the pulley 67, a plurality of grooves 68 formed along the rotation axis direction of the pulley 67 are arranged at substantially equal intervals in the circumferential direction of the pulley 67 (refer to FIG. 5).　　[0046] The driving unit 34 is used to drive the twisting belt 53 and the twisting belt 63 in common, and is provided in each false twisting device 15 individually. As shown in FIG. 3, the drive part 34 is arrange|positioned above the circular plate 31, for example. The drive unit 34 has a motor 71 (the “belt drive source” in the present invention) as a power source, and a pulley 72 connected to the rotating shaft of the motor 71. The rotating shaft of the motor 71 extends diagonally upward toward the working space 8 side. The pulley 72 is arranged diagonally above the motor 71.

First, as shown in FIG. 2, the circular plate 31 is driven to rotate in the direction of the arrow (clockwise in FIG. 2) by a motor (not shown) centered on the shaft 41.　　[0049] Next, the operations of the belt unit 32 and the belt unit 33 will be described using FIGS. 2 and 5. As shown in FIG. 5, when the rotation axis of the motor 71 of the driving unit 34 rotates in a predetermined direction (counterclockwise in FIG. 5), the pulley 72 connected to the motor 71 and the pulley 72 wound The belt 35 and the power of the motor 71 are transmitted to the pulley 55 of the belt unit 32, the pulley 65 of the belt unit 33, and the pulley 67. 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 pulley 65 is in contact with the outer surface of the belt 35, 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 (clockwise direction in FIG. 5) opposite to the rotation direction of the pulley 55 and the like. Here, the teeth 75 of the belt 35 mesh with the grooves 56, 68, and 73 of the pulleys 55, 67, 72, and the teeth 76 mesh with the groove 66 of the pulley 65, thereby preventing the belt 35 from sliding with respect to the pulley 55 and the like.　　[0050] When the pulleys 55 and 65 rotate as described above, the pulleys 51 and 61 rotate integrally with the pulleys 55 and 65, respectively. As shown in FIG. 3, since the pulley 55 and the pulley 65 rotate in mutually opposite directions, the pulley 51 and the pulley 61 rotate in mutually opposite directions. By this, power is transmitted to the twisted belt 53 and the twisted belt 63. Here, the portions of the twisted belt 53 and the twisted belt 63 on the side close to the disc 31 respectively travel in the same direction with respect to the disc 31. In addition, since the twisting belts 53, 63 are driven, the pulleys 52, 62 are driven to rotate, respectively.　　[0051] In this way, the yarn Y1 is sandwiched by the loop portion 42 of the rotating disc 31 and the traveling twisting belt 53, and the yarn Y1 is Z-twisted. In addition, the yarn Y2 is sandwiched by the loop portion 42 and the twisting tape 63, and the yarn Y2 is S-twisted. That is, the yarn Y1 and the yarn Y2 are twisted in mutually opposite directions.　　[0052] As described above, each of the plurality of false twisting devices 15 includes a motor 71 that drives the twisting belt 53 that twists the yarn Y1 and the twisting belt 63 that twists the yarn Y2, respectively. That is, each of the false twisting devices 15 is independently driven by a separate motor 71. In this case, compared to the case where a plurality of false twisting devices 15 are driven by a single motor in common, the size of each motor 71 is reduced, and the noise and vibration emitted from each motor 71 are extremely small, so it is possible to reduce noise and vibration. In addition, it is not necessary to arrange a member for power transmission for driving the plurality of false twisting devices 15 in common, so that the entire false twisting machine 1 can be downsized. In addition, the power transmission mechanism becomes compact, so maintenance can be facilitated.　　[0053] In addition, since the plurality of false twisting devices 15 are individually provided with motors 71, the plurality of false twisting devices 15 can be independently controlled. For example, when yarn breakage or the like occurs and it is necessary to stop any one of the plurality of false twisting devices 15, the false twisting device 15 is stopped only by stopping the motor 71 of the false twisting device 15. That is, even if there is no mechanism for separating the belt 35 from the pulleys 55 and 65, each false twisting device 15 can be individually stopped, so the structure of the false twisting device 15 can be simplified. In addition, by making the traveling speeds of the twisting belts 53 and 63 different between the false twisting devices 15 according to the output of the motor 71, the speed at which the yarns Y1 and Y2 are twisted can be different between the false twisting devices 15. Thereby, in the false twist processing machine 1, a plurality of types of yarns Y can be produced.　　[0054] In each of the plurality of false twisting devices 15, the inner surface of the belt 35 is in contact with the pulley 55, and the outer surface is in contact with the pulley 65. Via this belt 35, the power of the motor 71 is transmitted to the pulley 55 (and the pulley 51) and the pulley 65 (and the pulley 62) in mutually opposite directions. Thereby, the twisting belt 53 and the twisting belt 63 are driven, and the yarn Y1 is twisted by the twisting belt 53 and the disc 31, and the yarn Y2 is twisted by the twisting belt 63 and the disc 31. Y1 twists in the opposite direction. Thereby, there is no need to use a long belt for driving a plurality of false twisting devices 15 in common, and each false twisting device 15 can be driven by a belt 35 whose size can be accommodated in each false twisting device 15.　　[0055] In addition, the pulley 65 is in contact with the outer surface of the belt 35, and the pulley 67 is in contact with the inner surface of the belt 35. That is, the belt 35 is wound in an S-shape or a Z-shape with respect to these pulleys. Therefore, the winding angle of the belt 35 with respect to the pulley 65 can be increased, and the contact area between the belt 35 and the pulley 65 can be increased, so that the belt 35 can be prevented from sliding with respect to the pulley 65.　　[0056] In addition, the teeth 75 formed on the belt 35 mesh with the grooves 56 of the pulley 55, and the teeth 76 mesh with the grooves 66 of the pulley 65. Therefore, the belt 35 can be prevented from slipping with respect to the pulleys 55 and 65, and the power of the driving unit 34 is stably transmitted to the twisting belt 53 and the twisting belt 63. Therefore, the number of twists per unit length of the yarns Y1 and Y2 hardly fluctuates. This can suppress the deterioration of yarn quality. In addition, it is possible to suppress variation in yarn quality among the plurality of false twisting devices 15.　　[0057] Next, a modification example in which a change is added to the above-mentioned embodiment will be described. In addition, about the part which has the same structure as the above-mentioned embodiment, the same code|symbol is attached|subjected and the description is abbreviate|omitted suitably. [0058] (1) In the above embodiment, a plurality of teeth 75 and 76 are formed on the inner surface and the outer surface of the belt 35, respectively, and a plurality of teeth are formed on the outer peripheral surfaces of the pulleys 55, 65, 67, and 72, respectively. There are two slots 56, 66, 68, and 73, but it is not limited thereto. That is, as shown in FIG. 6, in the false twist device 81, the pulley 55a of the belt unit 32a, the pulley 65a of the belt unit 33a, the pulley 67a as an auxiliary pulley, and the drive unit 34a No groove is formed on the peripheral surface of the pulley 72a. In this case, for example, a belt 35a having no teeth such as a flat belt is wound around the pulleys 55a, 65a, 67a, and 72a.　　[0059] (2) In the above-mentioned embodiment, the pulley 67 is arranged at a position on the opposite side of the pulley 55 with the pulley 65 interposed therebetween, but it is not limited to this. For example, as shown in FIG. 7, in the false twisting device 82, the driving section is arranged such that the position of the driving section 34 in the machine longitudinal direction is on the opposite side of the pulley 55 with the pulley 65 therebetween. 34, without the pulley 67, the pulley 55 and the pulley 65 are rotated in opposite directions to each other.　　[0060] (3) In the above-mentioned embodiment, the power of the motor 71 is transmitted to the belt units 32 and 33 via the pulley and the belt, but it is not limited to this. For example, a gear or the like may be arranged, and the power of the motor 71 may be transmitted to the belt units 32 and 33, and the twisted belt 53 and the twisted belt 63 may travel in mutually opposite directions. [0061] (4) In the above-mentioned embodiment, the shaft 41 spans the plurality of false twisting devices 15 and extends in the longitudinal direction of the machine table. However, the shaft 41 may be configured such that, for example, each false twisting device 15 is separately provided. , And are connected to a motor (not shown) separately installed on each false twist device 15.　　[0062] (5) In the above-mentioned embodiment, the motor 71 is arranged between the disc 31 and the pulley 72, but it is not limited to this. The motor 71 may be arranged on the side opposite to the disc 31 with the pulley 72 interposed therebetween, and the rotating shaft of the motor 71 may extend diagonally downward. Thereby, even when the size of the motor 71 is large, for example, the motor 71 can be arranged without affecting the size of the space between the disc 31 and the pulley 72.　　 [0063] (6) In the above-mentioned embodiment, the first heating device 13 of the false twisting machine 1 in the width direction of the machine bed goes downward as it goes to the downstream side in the yarn traveling direction, but it is not limited to this. For example, the false twist device 15 can be applied to various false twist processing machines such as the first heating device arranged substantially parallel to the machine width direction (see Japanese Patent Application Laid-Open No. 2016-223034 etc.).
