Abstract

PURPOSE:To feed turbine blades intermittently by each piece automatically by driving a pulse motor by means of a driving control signal to feed the turbine blade by each piece and stopping the same for a prescribed time by means of a braking control signal. PURPOSE:The pulses produced in a pulse generator 15 are fed to a gate circuit 16, and while this is open, the pulses are fed to a driver 12, thereby driving a pulse motor 10. At the same time, they are fed to a counter 17 and the result of counting is fed to a comparator 18. When the pulses inptted to the comparator 18 from the counter 17 attains a reference value, said comparator produces an output which is fed to the circuit 16 and closes this. The output of the comparator 18 is also fed to a rest time oscillator 20 as well, and the generated pulses are fed to a counter 21, the count output whereof is fed to a comparator 22. The comparator 22 compared the output of the counter 21 with the reference value, generates a driving control signal, and feeds this to the circuit 16, thereby opening the gate.
