ABSTRACT:
The present invention provides a unique method and system for automatically controlling the motion of a rotary ring twisting and winding device, provided with a rotary ring member rotatably mounted on a holder by way of a bearing mechanism, which is utilized for textile machines having a so-called ring traveller twisting and winding mechanism. The present invention is characterized in that the rotational speeds of the rotary ring member and spindles are continuously detected, and the detected rotational speed of the rotary ring member is compared with the desired rotational speed of the rotary ring member which is calculated by multiplying a predetermined ratio by the detected rotational speed of the spindles, and if it is detected that the rotational speed of the rotary ring member is out of control, the rotational speed of the rotary ring member is electrically controlled to return to a condition of satisfying a predetermined allowable controlled condition. The present invention is preferably applied to two types of rotary ring twisting and winding devices, one of which is provided with a magnetic bearing as the above-mentioned bearing mechanism, while the other one is a device provided with a ring motor for positively rotating the rotary ring member.
