ABSTRACT:
In a sortation conveyor for cartons and the like wherein selected cartons can be diverted out of the main line to a branch line by means of diverter wheels which are directed obliquely with respect to the main line and which pop up into the path of a carton traveling on the main line to divert it to an associated branch line, the diverter wheel assembly comprises a plurality of diverter wheels arranged in two rows extending transversely across the main conveyor line, with all of these wheels being skewed with respect to the main line so that they define a course directed toward their associated branch line, and also a single further diverter wheel which is located downstream from the two rows of wheels at a position overlapping but spaced from the adjacent side edge of the main conveyor belt or other main conveying means so that if a carton, particularly a large carton, extends beyond the two rows of diverter wheels, the extra diverter wheel will prevent such carton from making frictional contact with the main line conveying means and will at the same time propel it toward the branch line. Preferably this single diverter wheel is driven at a higher linear speed than the other diverter wheels so that it not only prevents a diverted carton from being pulled back onto the main conveyor line, but accelerates its movement to the associated branch line.
