Abstract
A conveyor system particularly configured for discrete parcels, which combines tilting tray concepts with “cross-belt” or powered conveyor concepts, which allows for the acceleration of parcels above one gravity force “G”. In one configuration, two levels can be used, the upper for larger packages, and the lower for smaller packages.
