ABSTRACT:
The present invention is directed to a carton sorting device which comprises a main conveyor and at least one subsidiary conveyor angled away from the main conveyor at a branching unit. The main conveyor is adapted to apply a lateral force to articles having a lateral dimension below a preselected value so as to urge such articles onto the subsidiary conveyor. Articles having a lateral dimension greater than said preselected value are not affected. In this way, a mixture of the small and large articles are divided into two streams, the main conveyor carrying a stream of larger articles and the subsidiary conveyor only a stream of smaller articles. The invention also makes provision for sorting streams of articles having differences in their longitudinal dimension.
