Berlin-based machine vision company Bi-Ber has installed about 100 optical empty mould check systems in confectionery factories throughout Europe. In addition to customer-specific designs, four standard systems for up to 1,050 mm wide moulds are now available. High-resolution GigE colour cameras detect any minimal product residues. The Windows-based inspection systems with uniform multilingual firmware are suitable for moulds made of all common materials: polycarbonate, metal, silicone.

The B(asic) model combines cameras, lighting, and a touch panel PC in a stainless-steel cabinet that is placed directly onto the conveyor system. It shields ambient light, ensuring high, repeatable image quality. The use of multiple cameras allows for a wide field of view at short working distances. Doors in the control cabinet ensure good accessibility.

The S(eparate) model offers all the advantages of the basic system in terms of accessibility and ambient light shielding. However, the imaging technology and the computer are installed in two separate enclosures. The cabinet with the operating panel can be freely positioned for easy access.

The F(lexible) model with a slim camera and lighting module also features a separate control cabinet and was developed especially for enclosed lines and low-height surroundings. It is also available as a multi-camera version for wide moulds.

The C(ompact) model is condensed to include only the minimum necessary equipment and does not contain a signal light. The control box with a touchscreen is attached directly to the camera housing. The compact model is particularly cost-effective and also suitable for lines with limited space. Bi-Ber is constantly developing its testing technology further and also offers customers special solutions as well as retrofit of existing systems.
