INSPECTION 24 PET planet Insider Vol. 18 No. 03/17 www.petpla.net High speed preform inspection system updated Polarised light is the key The PVS-3 preform vision system, developed by Sacmi’s Automation & Inspection Systems Division has given its first market showing at the last edition of the international K’ 2016 fair in Düsseldorf, Germany. Performance and flexibility are the key elements. The system can be equipped (on request) with the automatic centrifugal positioning unit which makes it suitable in terms of compactness and efficiency for the down- stream installation of any injection press, new or existing. of particular interest: it enhances efficiency and is nicely compact, making investment decisions regarding existing lines easier. For offline installation the traditional roller positioner is available, while the in-line solution can be equipped downstream with the “soft drop” system that delicately sets down preforms exiting the vision system in octabins. on line efficiency and extending monitoring, also remotely, to every stage of production. Thanks to the software platform, it is possible to equip the Sacmi PVS-3 with both black and white video cameras and ultra-high resolution colour acquisition devices; the latter are designed for thorough inspection of preform colour. Adding yet further value is Sacmi’s capacity to include all- round solutions, personalised according to the individual custom- er’s manufacturing requirements and the target market. Solutions that range from complete plant engineering design (injection presses, stretch-blow moulding and filling lines, robotised handling systems and Sacmi-built end-of- line systems) to a fast, efficient spare parts and after-sales service that is guaranteed by the Sacmi Global Network. www.sacmi.it After the trade fair ten machines have been installed and sold world- wide, from Spain to Vietnam. This demonstrates the market has been quick to respond to a solution that offers inspection rates of up to 72,000pph and a flexibility that the system can be installed both in-line with the press and offline. In case of in-line operation, the upstream automatic centrifugal positioner is INSPECTION S P E C I A L Sacmi’s PVS-3 spans from stand- ard checks such as inspection of the preform mouth to the finish (especially the thread), the body and the bottom. Optional features include the patented Sacmi “grille” method to intercept defects that can only be detected with polarised light, such as on-material stress, surface irregularities and watermarks etc. The PVS-3 installs the latest CVS 3000 64-bit software system developed by Sacmi and shared by all vision systems in the range. It ensures interoperability between machines and a fully integrated approach that Sacmi calls total quality control. The intercon- nected system is able to provide precious additional information
