发明名称 Sheet handling apparatus having controlled pressure rolls to ensure feeding of a single sheet
摘要 A currency note picking and feeding apparatus (10) includes feed belts (28) for feeding notes from the bottom of a stack of notes (20) to the nip of a rotating suction drum (22) and separating belts (64) of frictional material which engage with the periphery of the drum (22). The suction drum (22) grips and feeds the lowermost note to a further conveyor means (76,82,84), with the separating belts (64) holding back any notes superposed on the lowermost note. If a feeding failure of the drum (22) occurs, as recognized by photodetector (90) associated with the further conveyor (76,82,84) failing to sense the passage of a note within a predetermined time interval, then pivotably mounted pressure rolls (92) are caused to be moved temporarily into cooperative association with the suction drum (22) so as to press the notes present at the nip of the drum (22) and the separating belts (64) against the drum (22), thereby increasing the grip of the drum (22) on the lowermost note.
