Abstract

A real time radiographic test system comprises a protective housing and a conveyor for conveying articles to be tested through the housing. A real time radiographic test instrument is located in the housing for performing a real time radiographic test on the article. The real time radiographic test instrument includes X-ray equipment disposed for directing an X-ray beam within the housing in a direction which does not intersect the conveyor. An article-handling actuator is located in the housing for repositioning an article from the conveyor to a position in registry with the X-ray beam, for maintaining the article in registry with the X-ray beam while the real time radiographic test is performed on the article and thereafter returning the article to the conveyor. The article-handling actuator and the X-ray equipment are designed such that each article to be tested is positioned substantially identically relative to the X-ray beam.

Claims15

Dependent claims

A real time radiographic system for performing a real time radiographic test on an article, comprising:

a code reading station;
code reading means located at said code reading station for verifying the presence of an acceptable identifying code on an article and for producing a good data indication in the presence of an acceptable identifying code and a bad data indication in the absence of an acceptable identifying code;
a test station;
a real time radiographic test instrument located at said test station for performing a real time radiographic test on an article and producing corresponding test data;
first bypass means responsive to said bad data indication for causing the corresponding article to bypass said real time radiographic test instrument without being tested thereby;
data analysis means for analyzing said test data and producing said good data indication if said test data is acceptable and a bad data indication if said test data is not acceptable;
a reject station;
conveyor means for conveying a part through said code reading station, said test station and said reject station;
and reject means located at said reject station and responsive to a bad data indication for removing the corresponding article from said conveyor means.
