Polybag leading edge detection

When sending small parts, it is becoming increasingly common to use polybags in order to optimize the transport volumes and costs. These present great challenges to conveying systems, in particular singulation and accumulation conveyors, because it is necessary to precisely determine their leading edge. This is required to guarantee the object separations required by downstream processes. The light strips of reflex array photoelectric sensors offer the optimal solution for this application.
