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. Various reflex array photoelectric sensors reliably detect the leading edge of polybags depending on the requirements.

  • Following product families can be used
    • RAY10: 25 mm-high light array, detects objects ≥ 5 mm
    • RAY26: 55 mm-high light array, three variants, detects objects ≥ 3 mm, ≥ 5 mm or ≥ 10 mm
    • Display for predictive maintenance on the sensor; transmits maintenance signals to the PLC via IO-Link
    • Conveyor belt suppression for RAY26
    • Precise detection of leading edges
    • Outstanding ambient light immunity
    • Easy installation
    • Housing length: 200 mm to 1,200 mm (7.87" – 47.24")
    • Beam separation: 50 mm to 200 mm (1.97" - 7.87")
    • Number of sensing points: 2 to 8
    • IO-link allows for individual beam break information for product alignment
