Copy Counting for Printed Products via Jump Detection with Triangulation Laser Distance Sensors

In the printing industry, newspapers and magazines are conveyed on conveyor belts in what is known as a shingle stream, i.e. overlapping. The copies must be counted so that the downstream packaging unit can process the exact quantity. Since they lie on top of each other and vary in thickness, detection must take place independently of the absolute distance to the sensor. A triangulation laser sensor mounted above the conveyor belt reliably detects the units thanks to the integrated jump detection function. In this operating mode, the sensor reacts to measured value jumps on the folds.

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.
