A Garvens S2 Pharma checkweigher forms the heart of the ...
Mettler Toledo’s UK Product Inspection division has created a bespoke checkweighing, print and verification system for a new packaging line at AstraZeneca’s 100-acre Macclesfield site.
Already the site’s preferred checkweigher supplier, having installed some 15 Garvens Pharma machines there, the division was approached to develop a solution to scan, batch/date print and checkweigh “prescription-sized” packs of Astra Zeneca’s new Zomig migraine medicine. The company required a system that would ensure the highest scanning accuracy, cost-effective print capability and a checkweighing tolerance of +/- 200mg – a level sufficient to define whether the correct dosage instructions are contained in the pack.
Metter Toledo devised a “top and bottom feed system” embracing its “proven” Garvens S2 Pharma checkweigher, a Sick Pattern Matching Sensor – chosen for its ability to recognise the given number of pixels in a specified area – and a Wolke printer.
