Abstract
A plurality of drive rollers, flexibly supported, are positioned along the inside track of a document transport passageway to drive the documents therealong, and a plurality of idler rollers, in opposed relationship to the drive rollers, are positioned along the outside track of the passageway. Each of the drive rollers and the idler rollers is supported from a pivot pin offset from the center of the roller to permit the roller to be canted by reason of gravity and elastic force, and thereby drive the documents in a forwardly and downwardly direction against a fixed edge guide to insure straight and longitudinal travel of the documents at a predetermined level along the passageway.
Claims14
Apparatus for aligning documents comprising a passageway along which documents are transported in edgewise manner,
- rotatable drive means normally assuming an inclined attitude and engageable with the documents for driving thereof in a downwardly inclined direction along said passageway, and rotatable idler means operably associated with the documents and including bearing means pivotally supported off center of rotation of said idler means to permit said idler means to correspond with the attitude of said drive means in urging the documents into a longitudinally aligned position along said passageway.
In a document sorter having a hopper adapted to support a plurality of documents therein, feed and separating means adjacent said hopper for initiating transport of documents therefrom in singular manner, an upright passageway beyond the feed and separating means for transporting documents,
- rotatable drive means pivotally mounted to attain a normally inclined position and engageable with the documents for driving thereof downwardly within and along said passageway, and rotatable idler means operably associated with said drive means and including bearing means pivotally mounted off center of rotation of said idler means to permit said idler means to cooperate with said drive means as positioned to continually urge the documents into a longitudinally aligned attitude as the documents are transported along said passageway.
Apparatus for aligning documents including
- frame means,
- rotatable drive means pivotally supported off center of rotation thereof and engageable with the documents for driving thereof in a downwardly inclined direction, and
- rotatable idler means pivotally supported off center of rotation thereof and engagable with the documents and cooperating with said rotatable drive means for urging the documents into a longitudinally aligned position, said rotatable idler means including bearing means having a portion thereof supported from said frame means for providing said off center pivotal support of said idler means thereby permitting a normally inclined attitude of said rotatable idler means.
