Lower costs, higher efficiency
Even monitoring NTRM with laser sorters – a widely used solution – has its pitfalls. “Not only do laser solutions consume a lot of spare parts, they also require highly qualified operators and maintenance personnel. This creates major difficulties in everyday production. The lasers have to be calibrated and replaced regularly by external specialists,” explains Schuster. “If the manufacturer fails to adhere meticulously to the specified maintenance intervals, there will be a steady drop in sorting performance – which can lead to a total breakdown.”
PURE – the enhanced, camera-based belt sorter developed by the Hauni Group – solves all these problems. Its camera-based technology is more robust and easier to handle than laser systems. It requires few spare parts and, naturally, no replacement of lasers. Handling and maintenance are very easy, and employees can operate the system after just a short introduction.
“As a result, we can reduce maintenance costs by up to two thirds and the system achieves a constant sorting efficiency of more than 85 percent under optimum conditions, with a tobacco loss of less than 0.3 percent,” says Schuster. “In order to achieve this level of performance, our PURE family – developed in collaboration with the Fraunhofer Institute for Optronics, Systems Technologies and Image Exploitation – features the latest image processing technology, state-of-the-art cameras and LED lighting strips. We are proud to present our customers with the world’s most efficient optical sorter.”
