Sensor bridges the gap

Phil Dyas, SICK UK’s industrial sensor specialist, says: "Up until now, a clear gap had to be left between packs in order for an optical sensor’s beam of light to be returned by the reflector positioned on the opposite side of the conveyor. 

"The DeltaPac differentiates between packs in a completely new way, detecting changes in their outline contours at speeds of up to 3m/s and 200,000 units an hour. The result is more reliable upstream process control and downstream accuracy for printing, labelling and palletisation.”
