Sheet extraction system from bundle - has rotary suction rollers travelling along circular path past bundle magazine

摘要

The system extracts sheets stacked in bundles for transfer one by one into successive cassettes with first suction devices and driven by a conveyor. It comprises a magazine (1) accommodating the bundle (2), and past which a series of rollers (5) travel, each with second suction devices. They are so driven that they both rotate on their own axes and these axes travel along a circular path past the bundle and then past the conveyor (11). Each roller extracts the topmost sheet by suction, and transfers to a position in front of a cassette. The vacuum is then released and the sheet deposited in the cassette.
