<p>PURPOSE:To make executable the good automatic operation for rearrangement of rolls, even if there is breakage or wrong action of the detector, by actuating the sequential control with the signal produced from a different means when the detector is unactable. CONSTITUTION:The signal of each detector 101-10N is inputted to the transit time arithmetic unit 1 which operates the transit time; this transit time is inputted to the setting circuit 2 for setting the time. The outputs of detectors 101-10N are inputted to the control command unit possessing the command circuit 30 and command sequence 31, in order to sequentially actuate each equipments for continuing the automatic operation. The reference clock signal produced from the clock circuit 300 is compared with the output of the counter 301-30N corresponding to the transit time between the detectors 101-10N being set in the circuit 1; when these two make coincidence, the coincidence detecting circuit 311-31N produce the signal. When the output from the circuits 311-31N is not inputted to the detectors 101-10N, the flip flop circuits 321-32N produce signals and input them into detectors 101-10N at the set time.</p> |
