Abstract

PURPOSE: To make it possible to detect automatically any trouble of sensor which has been installed in order to detect the passing time point of the object to be conveyed, in such an automatic convey system where the object to be conveyed and informations concerning the object to be conveyed have been made to correspond to each other.
CONSTITUTION: In such a system that information processing unit CMP will perform the prescribed information processing only when either one of No.2 or No.3 sensor S2 or S3 detects pass of object P to be conveyed a certain time after No.1 sensor S1 detects the pass of the object to be conveyed and takes action; count repetition number N1 of information processing and operation number N2, N3 of sensor S2, S3, make sampling of each calculated value at a certain time interval, seek after ratio of sampling times N1 and N2, and also ratio of N1 and N3, and when either one of these ratios goes out of the specified range. Senser S2, S3 must be detected as "faulty".
