INSPECTION products 36 PET planet Insider Vol. 19 No. 07+08/18 www.petpla.net Inspecting PET preforms Sacmi offers three inspection systems for PET preforms, designed to respond to specific produc- tion needs and to meet any type of production require- ment in this field. The PVS-2 Plus was created for the specific purpose of supporting the quality control laboratory in carry- ing out sample checks on individual preform batches. At inspection rates of up to 1,200 pph, the system is able to carry out a complete set of checks, including dimen- sional, weight and cavity number reading checks. The PVS-5 system is a high-performance, compact machine designed to operate in line with the press, at speeds up to 60,000pph. The design stands out for its reduced footprint and increased efficiency, and integrates a centrifugal positioner to ensure correct preliminary positioning of the preforms before 100% production inspection. Both designs, intended for different and complemen- tary production fields and requirements, are completed by PVS-01, the new Sacmi machine allowing for off-line linear inspection of potentially defective preform batches. Replac- ing traditional carousels with side belts and conveyor belts results in a considerably simplified machine - making format changeover totally automated. Thanks to the self-adjustment features ensured by brushless motors, the system makes it possible to carry out real-time inspections of composite batches - with preforms of different sizes and diameters. In this case, too, the customer can equip the machine with a roller positioner - also fully automated. As a result, with PVS-01 the customer can set an inspection recipe and the machine autonomously adjusts itself to it - without any need to replace mechanical parts. Designed for off-line inspection of up to 36,000 pph, PVS-01 is equipped with a backlighting system which, like other proposed solutions, uses the inno- vative “grid” method to detect defects otherwise only visible with polarised light, such as any sign of stress on the resin derived from the cooling process and/or water present in the moulds (the so-called “watermark”). All Sacmi preform inspection systems designed by the automation & inspection systems division are also suitable for advanced management of statistical data and for interfacing directly with the customer’s ERP. Thanks to the CVS 3000 2.2, a 64 bit software, interoperability between machines is guaranteed via a direct system interface with the Sacmi super- visor Human Expertise for Reactive Engineering (H.E.R.E.) and with the possibility of monitoring, even remotely, all the efficiency parameters of a single machine, department, or multiple interconnected production units. www.sacmi.it Inspecting bottles for leakages And & Or releases complete inspection s y s t ems w i t h l e a k tester and artificial vision integrated. This system is said to be reliable, sensitive and accurate for produc- tions from 1,000 bph (linear machines) up to 55,000 bph (rotary machines). Having a wide range of models in between low speed and high-speed productions. The leak tester allows the detection of micro leakages, with a sensitivity of 0.2mbar (pores up to 0.1mm). If there are several consecutive faulty bottles, it is detected and a light warning alarm will go off. This system is said to be reliable and to avoid manual calibration. The leak tester calibrates automatically according to external condition changes, such as temperature, pressure, etc. In addition to leak testing through pressure decay method in empty bottles, it also offers:  Leak testers through vacuum decay method: used to detect leaks in hermetically sealed bottles;  Leak testers in caps through squeezing method: used to detect the correct hermetic closure of the cap in a filled bottle. The idea to integrate vision in the leak tester happened because of space optimisation needs in factories, as well as joining several pieces of equipment in one and optimis- ing investment costs (fewer conveyors, fewer additional structures, etc). The system includes the detection of leaks (pressure decay method), contamination measurements, ovality, colour, injection point positioning. The incorporation of several pieces of equipment in one can be offered in different applications in the And&Or machine portfolio:  Take out robot + integrated leak tester;  Lost dome trimming machine + integrated leak tester. www.andyor.com INSPECTION S P E C I A L
