ABSTRACT:
A machine for sorting packages having individual bar code identifications. The packages are received at an induction station and an induction conveyor moves the packages up to a gate which is driven by an actuator to allow individual packages to pass through the gate at predetermined intervals. The packages are driven by a transport mechanism along a slider bed having trap doors moveable between an elevated position in alignment with the slider bed and a lowered position providing openings in the slider bed for the packages to fall from the slider bed. The transport mechanism includes individual pushers to move over the slider bed spaced from one another by the predetermined interval so that each pusher receives a respective one of the packages from the induction conveyor and pushes that package along the slider bed. Receiving stations are positioned under the trap doors and a control is operable to move the trap doors between the elevated to the lowered position so that the packages drop from the slider bed into the receiving stations according to order lists and the bar codes used by the machine to recognize the packages and match them to the order lists and hence to a destination receiving station.
