Sealing Quality Evaluation System for Sealing Strips of Packaging Webs in a Packaging Machine

Abstract

An automatic heat seal quality control system (12) for automatically controlling the quality of heat seals at the longitudinal ends of a packaging web (3) of a sealing strip (6) in a heat seal station (7) of a packaging machine (1). A sealed package (5) containing a cast food product is continuously manufactured from a continuous longitudinal tube (2) filled with the cast food product. The automatic heat seal quality control system (12) is formed by folding the packaging web (3) longitudinally and overlapping its longitudinal ends, and heat sealing the overlapping longitudinal ends. This system (12) includes a visible light camera (19) designed to operate in the electromagnetic spectrum visible to the human eye in order to capture and output a visible light digital image, and captures and outputs a visible light digital image.
