A sorter for separating waste material such as aluminum cans, large plastic containers, cardboard containers, cardboard, small lumber or wood material, paper and similar lightweight material by directing the waste material to be sorted downwardly onto pairs of elongated driven rollers which are arranged for gripping and pulling paper and similar material downwardly between adjacent rollers of a pair while aluminum cans and large plastic and cardboard containers will move longitudinally on the rollers with the plastic containers being lifted upwardly and discharged onto a conveyor and the cans being discharged from the ends of the rollers. The rollers have a spiral rib thereon to facilitate gripping of paper material and movement of the aluminum cans and containers. A kicker, in the form of a rotatable brush, is oriented above the discharge end of the rollers for lifting large lightweight material such as large containers upwardly along the interior of a curved deflector onto a conveyor.

A sorter for separating generally cylindrical aluminum beverage cans from paper material, items larger than cans and material thicker than paper material comprising a plurality of generally horizontally disposed, parallel, adjacent, cylindrical rollers to form an upwardly facing surface to receive mixed paper material and aluminum beverage cans at one end of the rollers, the other end of said rollers discharging cans therefrom, means rotatably driving said rollers, each of said rollers including a spiral rib on the exterior surface thereof for gripping paper material and moving it downwardly between adjacent rollers, said ribs engaging the external, curved surfaces of the aluminum beverage cans and items larger than cans and moving the cans and larger items toward the discharge ends of the rollers and engaging and moving the beverage cans longitudinally of the rollers and off discharge ends thereof, means conveying the aluminum cans from the discharge ends of the rollers and means conveying the paper material from under the rollers, said rollers including a plurality of adjacent upper rollers supported for rotation about axes oriented generally in the same plane and a plurality of adjacent lower rollers supported for rotation about axes oriented in the same plane disposed below the axes of the upper rollers, said upper rollers being mounted for resilient movement away from a normal position to enable the space between adjacent upper rollers and between the upper rollers and adjacent lower rollers to be enlarged for passage of material thicker than paper material, said means driving the rollers including a single drive chain to drive adjacent rollers in opposite directions with the lower rollers being arranged in pairs and the upper rollers being arranged in pairs between the pairs of lower rollers, each pair of lower rollers including a first lower roller rotating clockwise a second lower roller rotating counterclockwise and forming an upwardly facing trough therebetween with the upwardly facing surfaces of the trough moving upwardly and outwardly, each pair of upper rollers including a first upper roller rotating counterclockwise and a second upper roller rotating clockwise and forming an upwardly facing trough therebetween with the upwardly facing surfaces of the trough moving upwardly and outwardly, said first upper roller of each pair of rollers being disposed adjacent the second lower roller of each pair and forming an upwardly facing trough therebetween with the upwardly facing surfaces forming the trough moving downwardly and inwardly to grip and pull paper material downwardly between adjacent upper and lower rollers.
