Title
(EN) SHEET FEEDER WITH MODULAR SINGULATOR AND INTER-DOCUMENT GAP CONTROL BASED ON SHEET LENGTH
(FR) APPAREIL D'ALIMENTATION EN FEUILLES ET SON PROCEDE DE COMMANDE DE DEBIT
Abstract
(EN)
A sheet feeder apparatus and method with throughput control. By varying the speed at which sheets are fed from a supply, the sheet feeder apparatus and method assures that the throughput capacity of a downstream operation is never exceeded. The speed of the feed assembly (300) is controlled by a controller which receives information from photosensors (600) indicative of the length of the previously fed document to create an optimal inter-document gap. Singulator (400) is comprised of modular, pre-fabricated, self-contained conveyor sub-assemblies (460) which are easily placed upon and removed from shaft (420) and held in place by end cap (439).
(FR)
L'invention concerne un appareil d'alimentation en feuilles, et son procédé de commande de vitesse. Lorsqu'on fait varier la vitesse d'alimentation en feuilles à partir d'un dispositif d'alimentation, l'appareil d'alimentation en feuilles, et son procédé garantissent que la capacité de débit d'une opération avale n'est jamais dépassée. La vitesse varie en fonction de la longueur des feuilles fournies. En outre, les opérateurs ayant un niveau de compétence minimal peuvent remplacer rapidement les composants déchirés.
