Abstract
The present invention is directed to a mechanism for the handling of and the singulating of a stack or plurality of aligned and substantially flat materials such as for example, sheets of paper, cards, printed flyers, envelopes, checks, business cards, labels, other printed documents and the like. There is incorporated into the mechanism novel systems and assemblies which control the rate of the advance of the stack of materials, which advance is effected by an amplitude or magnitude of a unidirectional jogging motion. The magnitude is a function of the attitude of the stack or the angle formed with the horizontal of the leading sheet of the stack. There is also provided a pulsing mechanism for pulsing, synchronously with jogger belts of an input conveyor assembly for joggingly advancing the plurality of flat materials, the first singulator assembly which pulsing enhances the action of singulation of the plurality of flat material. The pulsing of the first singulator assembly results in an action which is similar to the human thumb action in the dealing of, for example, cards from a deck of cards. There is also provided a sensor assembly for sensing an inclination of the leading pi…
