Verfahren zur optischen Kontrolle von Blisterverpackungen

摘要

For optically inspecting the contents of blister packages 10 by means of image recognition, an illumination device is used which takes the form of a chamber 30 of which all interior walls are provided with sheet-shaped electroluminescent capacitors 32. These capacitors provide an extremely uniform, diffuse illumination so that reflections, which occur specifically with aluminium blister sheets and impair the image recognition, are largely avoided.
