MODULAR LINK CONVEYOR BELT PACKAGE SORTATION SYSTEM

摘要

A sortation system (10) and related method for sorting coded packages (P) utilize a continuous conveyor belt (11) including modular links (26) for side and elevational flexing. A frame (12) supports the modular link conveyor belt (11) such that the plane of the belt forms an angle to the horizontal plane as the belt (11) travels along an endless path. A stationary ledge (25) mounted to the frame (12) provides sufficient differential frictional drag to retard the packages (P) to align with a plurality of transverse pushers (13) for moving the packages along the endless path. A scanner (40) reads coded information (L) from the packages (P) and a controller (39) determines the proper distribution station (DS) for ejection of the packages (P) according to a selected parameter of the coded information. Controlled pneumatic valves (35) actuate pneumatic cylinders (44) and corresponding pivotal blades (43) to eject the packages (P) at the determined distribution stations (DS). Collection bags (37) are provided around the periphery of the conveyor belt (11) and the ledge (25) at each distribution station (DS) to collect the ejected packages (P) for further sorting or distribution.
