Patent ID: 8522982

Claim:
A method for inspecting, with the aid of a machine ( 1 ), transparent or translucent hollow articles (Aj) streaming at high speed in succession, past a series of monitoring stations each comprising at least one sensor (Ci) delivering an output signal (Si(j)) for each article (Aj) traveling past a sensor by considering that a sensor is able to see at least one article (Aj) travel past before the previous article (Aj−1) goes past the last sensor, the output signals (Si(j)) being processed so as to determine a result (Rj) indicating the compliant articles and the defective articles, characterized in that it consists in implementing at least one phase of assessing the setting of the machine consisting: in choosing compliant and defective reference articles (A′(j)), for each reference article (A′(j)), recording the output signals (S′i(j)) of the sensors with each of which are associated an identifier for the reference article concerned and an expected result (R′a(j)) regarding the compliant or defective character of the reference article, in selecting together, during the processing of the signals, at least two recorded output signals [S′a(j)], [S′k(j)] corresponding to one and the same reference article, so as to obtain after processing, a result (R′j) regarding the defective or compliant character of the reference articles (A′j), and in comparing the result obtained by processing (R′j), regarding the defective or compliant character of each reference article with the expected result (Ra′(j)) associated with each reference article so as to deduce the quality of setting of the machine; and, further characterized in that it consists for the articles (Aj) inspected in the course of the inspection phase: in recording the output signals (Si(j)) of the sensors (Ci), while associating with each of them an identifier (j) for the article concerned (Aj), and during the processing of the signals, in selecting together at least two recorded output signals (Si(j), Sk(i)) corresponding to one and the same article, doing so for all the articles, so as to make it possible to take into account, by article (Aj), the output signals (Si(j), Sk(j)).
