Measuring the Unwinding and Winding of Films on Rollers with Laser Distance Sensor Triangulation

Coated, high-gloss films are used to manufacture batteries. In order to detect their level on winding devices, laser distance sensors triangulation measure the exact distance – regardless of shape, color or surface. In this way, it is precisely determined on the unwinder how much material can still be unwound; on the rewinder, it is determined how much space there is available for material on the roller. The film is wound or unwound at a speed of up to 10 m/s for coating. The measured values are output via Ethernet interface and further processed.

Laser Distance Sensors Triangulation

The contactless laser triangulation sensors work according to the angle measurement principle, which enables reliable and highly precise measurement in the close range up to 1,000 mm. The triangulation sensors deliver stable measured values regardless of colors, shapes, rough and textured surfaces.
