CAPS & CLOSURES 25 PET planet Insider Vol. 20 No. 01+02/19 www.petpla.net easily. For the first time the CapWatcher Q-Line also checks the quality of the tamper evident band. For folded bands, additional attention is paid to the qual- ity of the slit. This makes it possible to detect worn knives or problems with the temperature of the blade at an early stage. In the case of injection-moulded tamper evident bands, inspections are in place for long and short shots between the bars, which would question the functionality of the closure. Another technical highlight is the measurement with a temperature sensor. This sensor makes it possi- ble to give each closure a timestamp. Closures, which obviously have been on the road for a longer time than the average of the last tested closures, are indeed inspected and their results included in the summary. However, the measurement results do not have any influence on possible changes to the process because they are not further processed for this case. This ensures that closures from the past have no influence on current line optimisations. Another value of the temperature sensor is that one is able to make a pre- diction about the shrinkage behaviour of the closures. This means that a closure manufacturer can ensure that the clo- sure at the planned time of the applica- tion has exactly the dimension that he assures to its customers. With eight high-resolution cameras, accuracies in the hundredth of a millimeter range and more than 40 inspection criteria per cap, the CapWatcher Q-Line collects, visualises and reports on quantitative statistical data at a rate of 60 closures/s in just 1min evaluation. Due to the efficiency, the system already offers the security of high quality closures on the production line - not after being checked by a quality lab. High line output Increasing the capacity utilisation of a production line is another of the goals when using Industry 4.0 applica- tions. An essential component of this is that you get as many elements of a production line as possible from a single source. Dr Fuhrmann states “Although we do not produce injection moulding systems, in the future all customers will be able to source from Intravis pro- duction. From now on, aside from our cooling and cross conveyors as well as our CapWatcher product family we also offer our own cap sorter, the Intravis CapFeeder.” With a capacity of up to 288,000cph, the sorter is also a power- ful infeed system and, in combination with the CapWatcher S-Line, the fastest closure inspection system line in the plastics industry, states Intravis. Extended product family In the area of standard beverage closures, Intravis brings the quality lab into the production line with the Cap- Watcher Q-Line described above. In contrast, the enhanced CapWatcher S-Line focuses entirely on the reliable high-speed inspection of beverage closures. At test speeds of up to 80, six cameras provide all the informa- tion needed to sort the closures with the highest precision. With the CapWatcher Slitter, Intravis offers a compact system for closure inspection after the slitting process. In addition to reliable cavity readings, this system is equipped with a comprehensive range of spin- dle statistics, so that seals and error types can be clearly assigned and traced. Furthermore, the system offers the improved high-voltage test for non-contact control of the microhole closures around the injection point and inspection of the slit quality. The fourth member of the product family is the CapWatcher SC. It serves the entire range of closures outside the standard beverage closures such as sports caps, flip-top caps or large oil closures. The product portfolio is rounded off by integrated systems for the inspection of single or multi- part closures in assembly handling systems or in feeding systems of large filling lines. Industry 4.0 applications are and will remain a current topic. Intravis GmbH has used its experience of recent years to be able to offer its cus- tomers the best possible solutions in the future. Not only that the new Cap- Watcher Q-Line now offers an even more powerful system for cap testing, which supports industry 4.0 applica- tions such as self-regulating injection moulding machines with its high-preci- sion testing. By expanding the product range with its own sorter, they now have another important element of the downstream equipment of a closure production in their portfolio. www.intravis.de product development caps & closures design high cavitation moulds multi-component moulds closure production systems after sales service competent – professional – inspiring Dr.-Walter-Zumtobel-Strasse 9 | 6850 Dornbirn | Austria | www.z-moulds.com SAVE THE DATE Plastico Brasil March 25th- 29th, Sao Paulo Plastimagen April 2nd- 5th, Mexico City
