(54) Driving control system for spinning machine


(57) The present invention provides a driving control system that allows a spinning machine with a large number of spinning units to continue its operation even during an instantaneous electric power failure. The driving control system works for a spinning machine having a plurality of spinning units, individual driving devices 508 provided for the respective spinning units to drive members acting directly on a bundle of fibers or a yarn, a shared driving device 50A provided to drive all of the plurality of spinning units 2, and a intra-frame member driving device 50C that drives members not acting directly on the bundle of fibers or yarn. The driving control system includes electric power failure detecting means 56 for detecting an electric power failure in a system electric power source 51 for the driving devices 50A, 50B, 50C, deceleration control means 57 for controllably decelerating the intra-frame member driving device 50C, and supply means 54 for supplying the individual driving devices 50B for the respective spinning units with regenerative electric power resulting from the deceleration control (Fig.1).
