Abstract

PURPOSE: To detect surely and remove automatically a bad printing blank and generate an alarm by a method wherein a discriminating process is effected by comparing digital data showing an amount of reflected light beams at every sampling points with reference data to detect the bad printing blank.
CONSTITUTION: A reflection type photoelectric detecting head 2 scans a line (a) on a printing surface β as the printing blank α is moving and passing and outputs an electric signal in proportional to the amount of the reflected light beams. This electrical signal is A/D converted and the digital value thereof is taken into a sampling pulse outputted from a pulse generator 3 after the pulse for the timing of a machine is outputted from a proximity switch 4. Thus, the data is taken from 10 cans and ten sets of the maximum and minimum data are memorized at every sampling pulses and further the reference data are set by providing clearances to respective maximum and minimum values. This reference data are compared with respective data from the eleventh can and when respective data are within the reference data, it is determined as a normal can, on the contrary, when they are out of the reference data, it is determined as a bad can.
