The Whisper Laner from Materials Handling Systems (Baltimore, MD) can lane containers by color, orientation, fill height, or bar codes from 1:2 lanes up to 1:8 lanes.
Laner can divert every other container at speeds of 1 products/min with no moving parts. Product is conveyed into the laning area where it is supported on a pitch by two guide rails. At the point of dividing the guide rails are taken away and compressed air tips the product left or right off the pitch. The chains split away from each other taking the product down the appropriate lane. The entire process is done without contacting the product.
