  • Patent number: 4966357
    Abstract: Apparatus for feeding sheets from a pluraltiy of supplied to an output location in which a toggle linkage normally releasably positions the conveyor in an operative position from which is may be moved around an axis adjacent to one of its longitudinal edges to permit access to the feed path.
    Type: Grant

  • Patent number: 4877230
    Abstract: A sheet dispenser for selectively dispensing predetermined numbers of sheets, for example, paper currency of different denominations and having plural input stations each receiving a stack of each bill denomination. A feed roller at each station has a high friction surface portion which engages a bottom sheet and feeds the sheet between the feed roller and a cooperating stripper shoe to assure single sheet feeding. An elongated acceleration belt extends beneath all of the feed rollers. Cooperating acceleration pinch wheels form a nip with the belt for accelerating a sheet entering the nip. A curved resilient guide cooperates with each feed roller to guide sheets passing the stripper shoe toward its associated acceleration nip. The sheets pass along the acceleration belt to an outfeed stacker including a stacker wheel to facilitate the formation of a neat stack of sheets. Sensors detect the entry of a sheet into each acceleration nip and to assure proper positioning of the feed roller.

  • Patent number: 4660822
    Abstract: A sheet dispenser for selectively dispensing predetermined numbers of paper currency of different denominations and having plural stations each receiving a stack of bills. The dispenser includes a feed roller with a pair of flanges. The high friction surface portion of the feed roller flanges engage a bottom sheet and feed it between the feed roller and a stripper shoe to assure single sheet feeding. Elongated acceleration pinch wheels each form a nip with the belt for accelerating a sheet entering the nip. A curved resilient guide cooperates with each feed roller to guide sheets toward its associated nip. The sheets pass along the acceleration belt to an outfeed stacker including a stacker wheel. Sensors detect the entry of a sheet into each acceleration nip and control positioning of the feed roller. Notches in the flanges of each feed roller assure movement of the leading edge of the sheet into the feed nip. Each feed roller rotates one revolution for each sheet to be dispensed.
