Inside POLYPHEM wt: The use of LEDs in the lighting unit combined with intelligent lighting control ensures smooth lighting of the control area without warming the products

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 colored tablets, capsules, dragees, syringes, and vials or applicators. Beyond merely checking the presence, the system reliably detects errors in color, form, dimension and position of the contents. It also recognizes contaminations, damages, or overfilled pockets.

Among others, POLYPHEM wt inspects colour, form, size and positioning of tablets, capsules and dragees in blister packaging

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 color 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.

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
