Title:
CONTROL DEVICE FOR INDEXING INTERMITTENT ROTOR
Document Type and Number:
WIPO Patent Application WO1982000264
Kind Code:
A1
Abstract:
A control device for indexing an intermittent rotor for the turret of an NC lathe or the like, which comprises code signal generator means (LS1, LS2, LS4, LS8, DG) for generating a different code signal at each stopping position of the rotor (TR), strobe signal generator means (LSS, DG) for generating a code signal reading strobe signal at each stopping position of the rotor (TR), a first comparator circuit (COMP1) for comparing the indexing instruction value with the code signal, a counter (CT) for counting the strobe signals and preset by the code signal, and a second comparator circuit (COMP2) for comparing the counted value of the counter (CT) with the code signal value. When a coincidence is detected by both comparators (COMP1, COMP2), an indexing complete signal is generated thereby controlling the indexing of the rotor with high reliability.
