A.1.2 Example of "Flying shears"
The example shows a typical application for cutting the continuously produced
material to length.
The incoming material is conveyed by the feed axis (Axis 1) in a continuous
motion, and cut to length "on the fly" by the severing axis (Axis 2).
The marks on the surface of the material identify the severing points. A sensor
detects the mark, and sets the process value of the feed axis (Axis 1) to -500 mm.
This sensor signal also triggers synchronization of the shearing axis. During axis
synchronization, the shearing blade approaches the mark. The material is cut after
the shearing axis is synchronized. Finally, the flying shears are returned to home
position, waiting for the next mark.
