Next, the operations of the belt unit 32 and the belt unit 33 will be described with reference to FIGS. 2 and 5. As shown in FIG. 5, when the rotation axis of the motor 71 of the drive unit 34 rotates in a predetermined direction (counterclockwise in FIG. 5), the pulley 72 connected to the motor 71 and the belt wound around the pulley 72. 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 35. Here, since the inner surfaces of the belts 35 are in contact with the pulleys 55, 67, and 72, 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.

Here, the teeth 75 of the belt 35 mesh with the grooves 56, 68, 73 of the pulleys 55, 67, 72, and the teeth 76 mesh with the grooves 66 of the pulley 65, thereby preventing the belt 35 from slipping with respect to the pulley 55 and the like. ..

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 opposite directions, the pulley 51 and the pulley 61 rotate in opposite directions. As a result, power is transmitted to the twister belt 53 and the twister belt 63. Here, of the twister belt 53 and the twister belt 63, the portions of the twister belts 63 near the disk 31 travel in the same direction with respect to the disk 31. The pulleys 52 and 62 are driven to rotate driven by the twister belts 53 and 63, respectively.

In this way, the thread Y1 is sandwiched between the ring portion 42 of the rotating disk 31 and the traveling twister belt 53, and the thread Y1 is Z-twisted. Further, the yarn Y2 is sandwiched between the ring portion 42 and the twister belt 63, and the yarn Y2 is S-twisted. That is, the yarn Y1 and the yarn Y2 are twisted in opposite directions.

As described above, each of the plurality of false twisting devices 15 includes 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 false twisting devices 15 is independently driven by individual motors 71. In this case, the size of each motor 71 is smaller than that in the case where a plurality of false twisting devices 15 are driven in common by one motor, and the noise and vibration generated from each motor 71 are significantly reduced, so that noise is generated. , Vibration can be reduced. Further, since it is not necessary to arrange a power transmission member for driving a plurality of false twisting devices 15 in common, it is possible to reduce the size of the false twisting machine 1 as a whole. In addition, since the power transmission mechanism becomes compact, maintenance can be facilitated.

Further, since the plurality of false twisting devices 15 individually include the motor 71, the plurality of false twisting devices 15 can be controlled independently. For example, when it becomes necessary to stop any one of the plurality of false twisting devices 15 due to thread breakage or the like, the false twisting device 15 can be stopped by simply stopping the motor 71 of the false twisting device 15. Stop. That is, since each false twisting device 15 can be stopped individually without a mechanism for separating the belt 35 and the pulleys 55 and 65, the structure of the false twisting device 15 can be simplified. Further, by making the traveling speeds of the twister 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 made different between the false twisting devices 15. can. Therefore, the false twisting machine 1 can produce a plurality of types of yarns Y.

Further, in each of the plurality of false twisting devices 15, the inner surface of the belt 35 contacts the pulley 55 and the outer surface of the belt 35 contacts the pulley 65. 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 opposite directions via the belt 35. As a result, the twister belt 53 and the twister belt 63 are driven, the thread Y1 is twisted by the twister belt 53 and the disk 31, and the thread Y2 is twisted by the twister belt 63 and the disk 31 in the opposite direction to the thread Y1. Therefore, it is not necessary 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 having a size that fits in each false twisting device 15.

Further, the outer surface of the belt 35 comes into contact with the pulley 65, and the inner surface of the belt 35 comes into contact with the pulley 67. That is, the belt 35 is wound around these pulleys in an S-shape or a Z-shape. 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 slip of the belt 35 with respect to the pulley 65 can be suppressed.

Further, the teeth 75 formed on the belt 35 and the grooves 56 of the pulley 55 mesh with each other, and the teeth 76 and the grooves 66 of the pulley 65 mesh with each other. Therefore, the slip of the belt 35 with respect to the pulleys 55 and 65 is prevented, and the power of the drive unit 34 is stably transmitted to the twister belt 53 and the twister belt 63, so that the number of twists of the threads Y1 and Y2 per unit length is increased. It becomes difficult to fluctuate. Therefore, deterioration of yarn quality can be suppressed. Further, it is possible to suppress the variation in yarn quality among the plurality of false twisting devices 15.

For example, as shown in FIG. 7, in the false twisting device 82, the drive unit 34 is arranged so that the position of the drive unit 34 in the longitudinal direction of the machine base is opposite to the pulley 55 with the pulley 65 in between. The pulley 55 and the pulley 65 may be rotated in opposite directions without providing the pulley 67.

(3) In the above embodiments, the power of the motor 71 is transmitted to the belt units 32 and 33 via the pulley and the belt, but the present invention is not limited to this. For example, a gear may be arranged to transmit the power of the motor 71 to the belt units 32 and 33 so that the twister belt 53 and the twister belt 63 travel in opposite directions.

(4) In the above-described embodiment, the shaft 41 is assumed to extend in the longitudinal direction of the machine base over the plurality of false twisting devices 15, but the shaft 41 is provided individually in each false twisting device 15, for example, and , Each false twisting device 15 may be individually connected to a motor (not shown).

(5) In the above-described embodiment, the motor 71 is assumed to be arranged between the disk 31 and the pulley 72, but the present invention is not limited to this. The motor 71 may be arranged on the side opposite to the disk 31 with the pulley 72 interposed therebetween, and the rotation axis of the motor 71 may extend diagonally downward. Thereby, for example, even when the size of the motor 71 is large, the motor 71 can be arranged without being affected by the size of the space between the disk 31 and the pulley 72.

(6) In the above-described embodiment, the first heating device 13 of the false twisting machine 1 is set to move downward toward the downstream side in the yarn traveling direction in the machine base width direction, but the present invention is not limited to this. .. For example, the false twisting device 15 can be applied to various false twisting machines such as those in which the first heating device is arranged substantially parallel to the machine base width direction (see Japanese Patent Application Laid-Open No. 2016-22304). ..
