APPARATUS FOR THE ILLUMINATION OF A REGION OF A BOTTLE OR THE LIKE TO BE INSPECTED

The apparatus is used for testing the surface structure of hollow, cylindrical regions of transparent, hollow bodies (e.g. bottles) moved along a track. It comprises an illuminating device (10), a conveyor (14) by means of which the hollow bodies (34) are moved through an inspection region, and an i...

More Information
Summary:The apparatus is used for testing the surface structure of hollow, cylindrical regions of transparent, hollow bodies (e.g. bottles) moved along a track. It comprises an illuminating device (10), a conveyor (14) by means of which the hollow bodies (34) are moved through an inspection region, and an imaging device (12). The illuminating device (10) has several light sources (26) which are arranged so that, in every position within the inspection region (9), the hollow bodies (34) receive light at an angle of incidence such that the hollow bodies (34) act as wave guides and appear as secondary light sources with respect to the imaging device (12), so that the imaging device (12) yields a high-contrast image of the surface structures of the hollow bodies. The device is principally used for the testing of recycled bottles.
