ABSTRACT:
A method and apparatus for segregating articles, such as envelopes (14a, b, or c) bearing address labels (15) into separate groups, with all the articles in each group having the same unique mark (such as a zip-code-area mark). The apparatus includes a right angle conveyor (12) positioned perpendicular to a discharge conveyor (10), an article deflector plate (20), and two or more freely rotatable balls (38, 40) supported in contact with the right angle conveyor (12) and spaced laterally across the face thereof. At least one freely rotatable ball (38) is selectively removable from contact with the right angle conveyor (12) by a solenoid (18) acting through a beam (32) and a control arm (26). The solenoid (18) is activated by a signal from a detector (16) which detects a change in unique markings on address labels of articles just prior to their engagement with the selectively-removable, freely-rotatable ball and the right angle conveyor.
