A document-handling apparatus and method for transporting documents along a document feed path from an upstream end to a downstream end. The apparatus includes at least one document-handling subassembly along the document feed path for singulating the documents, controlling gaps between the documents, and conveying the documents toward the downstream end; a sensor mounted along the document feed path for sensing the positions of the documents and for generating position signals based on the document positions; and a control apparatus for receiving the position signals and for controlling the velocity and acceleration of the document-handling subassembly so as to regulate the size of the document gaps and to maximize document throughput. The document-handling subassemblies can include a stack advance mechanism, an input feeder, one or more singulators, and one or more output feeders. A trap can also be included to stop a document along the feed path. The apparatus can operate at accelerations as low as 0.5 g, enabling documents to be transported with constant motion through the apparatus, thereby maintaining efficient interdocument gaps without using high accelerations.

Apparatus and method for controlling a document-handling machine

The present invention provides an aligner apparatus which bottom edge aligns documents and separates documents and provides adequate gap between documents for subsequent processing. The an aligner apparatus includes first and second guide walls, forming an alley along the document feed path in which the documents are relieved of interdocument forces allowing bottom edge alignment of the documents with the document feed path. A trap assembly including first and second trap levers is lever mounted along the document feed path on a side of the guide wall and when actuated, cause opposing forces on one-another in order to grab the documents as they move along the feed path in the aligner apparatus so as to control the gap between the documents. It apparatus further provides an adequate gap between documents while reducing noise. Each trap lever has a head portion, which is fitted with a resilient pad, which is attached to the trap arm in a manner that forms a gap between the head and the pad. The resilient pad and the gap operate to reduce noise created by the trap arm when actuated.
