Article inspection apparatus |
摘要 |
An article inspection apparatus is capable of inspecting an article which cannot be sorted out by image processing or a diagnostic process that employs energy to be transmitted through the article. A hitting sound is generated by a hitting sound generating device when an article is hit, and is detected by a sound detecting device and analyzed by a detected-sound analyzer. The analyzed result is converted into a pattern by a detected-sound pattern generator, and the pattern is matched with registered reference patterns from a reference pattern registering device by a pattern matching device. Based on the result of matching, the article is sorted out by an article sorting device. It is possible to detect the material of a container, such as cans of aluminum and iron which are identical in shape and size to each other. It is also possible to check the amount of a substance in a container that cannot directly be seen, or inspect baked articles for pores contained therein.
