Title: Hartwin Stüwe: Innovator in Glass Inspection Technology
Introduction
Hartwin Stüwe is a notable inventor based in Hespe, Germany. He has made significant contributions to the field of glass inspection technology, holding 2 patents that showcase his innovative approaches to detecting flaws in glass items and container sealing surfaces.
Latest Patents
Stüwe's latest patents include a method for detecting flaws in the walls of hollow glass items. This invention involves a unique process where hollow glass items are inspected while rotating about their longitudinal axis. The method produces a series of images that are binarized using a grey-scale value threshold image. The threshold values are measured differently based on the fixed positions of radiation-receiving elements. The resulting images are combined in a histogram that adds up the frequency of defect pixels, allowing for a more accurate flaw-detecting evaluation.
Another significant patent is a method and device for examining a sealing surface of a container mouth. This invention utilizes a light source that emits tangential light beams onto the sealing surface. When these beams encounter a defect, they scatter, and the scattered light is detected by a sensor. An optical deflecting element is used to enhance the contrast between defects and reflections, improving the detection process.
