The system inspects length, shape and diameter along with common error types including short shots, bubbles, oil spots, burns, defor- mations and contaminations in the mouth area. Additional inspection cri- teria such as ovality, flash at the part- ing line, scratches and sealing surface notches are also incorporated. Ralph Möller, unit leader at Hansa-Hee- mann, Germany, sees the advantage of these features. “The PreWatcher is making our start up with preforms from recyclate much easier”, Möller states about his two inline-systems from Intravis. Highlight cavity reading The proprietary Intravis cavity reading software identifies the pre- forms by defined cavity numbers, which means that it can trace errors to specific cavities. The colour cam- eras detect deviations in colour and intensity as well as coloured streaks in the body and the bottom. Their high resolution provides detailed raw data that can help operators to make better decisions, including when exactly an object will be identified as a bad part and be thrown out. The PreWatcher III can work to very fine specifications and thus only throw out bad parts if the deviations are recognisable and the products could not be sold to the end customer, thus minimising waste. The precise inspection enables the wider use of materials such as recy- clate, without compromising end prod- uct quality. A newly-developed lighting technology, which is adaptable to the key features and characteristics of the object, enables a precise inspection with improved dynamics. www.intravis.de The PreWatcher III is optimized for an inline use
