Sheet coil uncoiling
To ensure a constant feed of material, the uncoiling speed of the sheet coil must be regulated. The DT20 Hi distance sensor measures the radius of the sheet coil over the entire uncoiling process. The DFS60 incremental encoder uses a friction roller to measure the uncoiling speed of the sheet metal. The measured values from both sensors are used to control the uncoiling speed and initiate automatic coil change.
