Heuft VX OCR system for packaging

Heuft Systemtechnik has developed a system for optical character recognition which identifies packaging that has not been coded or incorrectly coded in good time and withdraws it from circulation.

The Heuft VX OCR not only checks the presence of best-before dates (BBDs), barcodes or data matrix codes on filled packages but also verifies their correctness as regards to contents. The system achieves good detection accuracy due to an LED illumination, a high-resolution camera and the company’s reflexx image analysis technology, even at high line outputs of up to 72,000 individual packages per hour.

The system also reads the marking on packaging accurately in the most difficult ambient conditions such as in front of a dark background. The development can check up to two lines at the same time even in the high-speed section with the standard software. Incorrectly coded packages are consistently removed from the production flow. An automatic date adaptation prevents misadjustments and minimises the false rejection rate.
