ABSTRACT:
A first conveyor belt has a transverse tilt from horizontal and a wall along one side. Crushed plastic containers dropped onto the belt fall against the wall and are thus aligned under gravity action. The first belt transfers aligned containers to a second belt operating at a faster rate of speed and having a width capable of supporting only a single article in the transverse direction. The second belt transfers the containers to a third belt operating at a faster rate of speed than the second belt thereby further spacing the containers one from another. A scanner checks the spacing of each adjacent pair of containers and causes an air cannon to blow containers from the third belt when spacing does not conform to a predetermined spacing criteria. Containers falling from the end of the first belt and those blown from the third belt are received by a hopper having a conveyer therein which returns such containers to the first belt.
