ABSTRACT:
A spring coiling machine with an auxiliary drive and control has a feed roll driving clutch with inputs from both a main machine drive and from the auxiliary drive. The main drive is set to rotate feed rolls to advance a length of wire an increment less than that required for a coil spring of a predetermined configuration and dimension. The final increment of wire feed is then accomplished by the auxiliary drive, the clutch acting to render the latter effective as main drive rotational velocity drops off. An optical sensor responsive to the position of a leading end portion of the wire in the spring being coiled thereafter signals the auxiliary drive control to terminate wire feed. A fast response servo motor is employed as an auxiliary drive and a precise termination of wire feed is thus achieved to provide for precise end positioning. The clutch employed is unidirectional and termination of auxiliary feed may be accomplished by terminating forward drive or by reversing the servo motor. A bistable device maintains an "on forward drive" signal pending receipt of an "off forward drive" or "reverse" signal, the latter being supplied by said optical position sensor. The "on" signal for the servo motor may be provided in either event by a cam shaft position sensor operable when a main drive actuated wire feeding operation is partially complete.
