Abstract
An induction subsystem for a conveying system includes a plurality of induction conveying units that are controlled by a plurality of controls in a manner that delivers articles to a release conveyor with gaps between the articles that approach a desired length. The conveying units may be controlled using algorithms that examine a planned release time for an article and a time at which the article would be released were it to complete the rest of its travel through the induction subsystem at one or more nominal speeds. The difference is used to determine an appropriate speed for at least one of the conveying units. The conveying unit may alternatively be controlled using algorithms that determine desired speed ratios for the conveying units, and which may seek to control the centerline to centerline spacing of articles as they reach the release point such that desired gaps are created.
