Sectors such as the pharmaceutical, cosmetics and food industries in particular rely on blisters for packaging their sensitive products. With the camera system Polyphem wt, Laetus—a provider of systems for inline vision quality control and complete track & trace systems—offers a high-quality system designed for comprehensive inline quality control on blister machines. Regular advancements, as for instance the module Polyphem wt 3D for three-dimensional inspection, are made to enable meeting individual process requirements as well as new security standards.
Among others, Polyphem wt inspects colour, form, size, and positioning of tablets, capsules, and dragees in blister packaging.
A GAMP-compliant industrial computer with a touchscreen and a lighting unit with one or more integrated cameras build the basic structure of Polyphem wt. Various optional modules are meant to adapt the system to customer-specific process requirements. Polyphem wt 3D uses stereoscopy to evaluate height and colour and thus tries to detect double or broken content. The module is designed to be useful for inspections in low-contrast surroundings. Polyphem wt Pro TWIN+ should allow for controlling blisters successively from above and below, before and after sealing. Both modules can be combined with each other.
Inside Polyphem wt: The use of LEDs in the lighting unit combined with intelligent lighting control is meant to ensure smooth lighting of the control area without warming the products.
