Abstract

This system locates and scans address information on packages which have been faced with the intent of using the information to drive a display, which can be viewed by a human who keys information from the display for sorting purposes, or to drive an optical character recognition device which automatically performs recognition and sorting functions.

Parcel Positioning Scanning and Sorting System

This system locates and scans address information on packages which have been faced with the intent of using the information to drive a display, which can be viewed by a human who keys information from the display for sorting purposes, or to drive an optical character recognition device which automatically performs recognition and sorting functions.

A continuous motion belt 1 transports packages 2 at constant velocity throughout the sorting machine. Moving targets or "bull's-eyes" 3 are located at equally spaced intervals on the belt 1 to provide the facer, usually a human, with a target to place the portion of the package over which needs to be read at the scan station. Another target or bull's-eye 4 is projected onto the top of the package to assist in package positioning. This projection of the bull's-eye moves in synchronism with the transport via a mirror projection 12, over the area where the package is inducted onto the moving conveyor. A height detector 5 measures the vertical dimension of each package as it passes a fixed point on the transport. A dynamic focus drive 6 positions the scanner to accommodate packages of variable height. A scanner 7 views a predefined window area (which is the maximum anticipated area of interest) on the package as the package passes underneath the scanner.

The packages are positioned with the aid of the bull's-eye on the belt and projected bull's-eye, such that the area of inte...
