Polyphem blister pack inspection solution

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 offers a high-quality solution for comprehensive inline quality control on blister machines. Regular advancements, as for instance the module POLYPHEM wt 3D for three-dimensional inspection, enable meeting all individual process requirements as well as new security standards.

Versatile inspection solution

Whether medication, toothbrushes or chocolate confectionary – intact packaging of high quality is one of the prerequisites for presenting a product successfully. The camera system POLYPHEM wt convinces with a variety of control options for blister packaging that is filled with coloured tablets, capsules, dragees, syringes and vials or applicators. Beyond merely checking the presence, the system reliably detects errors in colour, form, dimension and position of the contents. It also recognises contaminations, damages or overfilled pockets.

Tailor-made adaptation

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 adapt the system to customer-specific process requirements. POLYPHEM wt 3D uses stereoscopy to evaluate height and colour and thus detects double or broken content. Moreover, the module is particularly useful for inspections in low-contrast surroundings. POLYPHEM wt Pro TWIN+ allows for controlling blisters successively from above and below, before and after sealing. Both modules can be combined with each other.

Always up to date

POLYPHEM wt inspects objects of the most diverse materials lying in blisters for errors and therefore ensures that faulty objects are reliably discharged from the production process. Laetus configures the modularly expandable system directly according to individual customer requirements and without additional programming effort. For more than 40 years and with more than 2,300 installed systems, POLYPHEM wt has met the highest demands in fill inspection and is constantly being refined.
