SK-400-C colour detection system

Making colour detection easy In an automotive wire production line, just one or two granules of a different colour can cause the contamination of approximately 200m of insulation cable, because of the difficulty of manually detecting the colour variation at a speed of 1,800m/min. a PC-based evaluation unit with 360° camera surveillance. The unit consists of four cameras, covered by a protective housing. This enables monitoring of the colour quality over the entire scope, and allows the tested colour quality to be documented, eg in the spool protocol.

in Pischelsdorf, Austria, as well as on automotive wire production lines at customers’ sites. The results revealed that recipes with 2.5 per cent masterbatch could be decreased to 1.5 per cent while still maintaining the same colour shade.

The immediate assurance of colour reliability eliminates colour complaints and faulty production. In addition, waste and scrap rates are reduced at start-up, during production and during colour changes. The system has undergone intensive testing on Rosendahl’s laboratory line

For this reason, Rosendahl has optimised a sensor system for colour detection. The SK-400-C can detect colour variations that the human eye cannot perceive. The system measures the main and stripe colours, as well as the stripe width, in accordance with previously set references. The main component is
