Detection and identification of disturbances by spectral analysis of structure-borne noise during the production of a sealing seam

When sealing, disturbances or errors can occur that impair the quality of the sealing seam and, in the worst case, lead to leaks. It is therefore important to identify and eliminate defective packages during production and to minimize the elimination by readjusting machine parameters. The aim of this article is the clear identification of seam quality problems on a vertical forming, filling and sealing machine SVE2520 by evaluating process parameters during the manufacturing process. For this purpose, the structure-borne noise is measured for each seal in order to identify not-usual curves. These not-usual curves are related to different disturbances or errors. By combining sensors technology, data analysis and step-by-step clustering, most damage images can be clearly differentiated from one another and that only by using the structure-borne noise
