All inspec- tion systems have an interface to the company’s internal production data acquisition system (PDA), so that each reel change is automatically stored with the respective roll number. The complete traceability is given and supports the acquisition of informa- tion. Film rolls can be automatically locked by the system without opera- tor intervention. This is made pos- sible by additional analysis software, which relates material, raw mate- rial and process parameters from the PDA system to the respective quality/ fi lm grade and leads to long-term statistical process control. Further use of OCS systems in the production process: • Raw materials will be inspected “inline” by an OCS Pellet Scanner (PS800C) • Compounds will be analysed “of- fl ine” by OCS Laboratory Extrusion Lines. components. The basis is provided by the sophisticated inspection tech- nology using the OCS Web Inspec- tion System FSP600, which detects and marks defects and immediately alarms the operator. However, a simple and user-friendly teach-in software is also essential. Defects are detected and classi fi ed accordingly. Mondi Gronau sees itself as a pioneer in the fi eld of holistic process analy- sis and integration in fi lm extrusion. “OCS Inspection Systems provide the basis for our process control. Bymeans of the extended networking of com- plete data stocks from the OCS analy- sis software and our PDA system, we can react faster to qual- ity varia- tionsand assist in the re- duction of scrap, r ewo r k and ma- chine downtimes, Olaf Brauckmann, Head of Technical Service at Mondi Gronau.” Mean- while almost all extrusion and con- verting lines are equipped with OCS inspection systems which support the daily quality assessment.
