Apparatus for detecting foreign material in a powder material

摘要

The present invention provides a foreign substance inspection apparatus (1) which obtains images of a powder material with a two-dimensional camera (9) and subjects the image data outputted from the camera to image processing, whereby foreign substances mixed into the powder material are detected. The foreign substance inspection apparatus (1) comprises a rotatably supported container (5) with an opening surface (3) in a substantially horizontal state; a liftably supported lift member (7) inside the container; a drive control device for controlling rotation of the container (5) and rise and fall of the lift member (7); a scraping plate (25) disposed on the opening surface (3) of the container (5); wherein the powder material contained in the container (5) is pushed upward with the rise of the lift member so as to be scraped with the scraping plate (25), and the two-dimensional camera (9) is located so as to obtain images of the surface of the powder material that is exposed on the opening surface (3).
