Synchronous Friction Vacuum Document Separator

This is a synchronous operating friction-vacuum document separator. Documents 9 are pushed along a pair of double restraint belts 3 slightly fanning the documents until the top document reaches separator drum 1 where it stops.

The stopping action is provided by the restraining force of belts 3. Such force is greater than the force exerted by the smooth surface on drum 1 and the picker belt which keeps the top document in the pick position. As porting section 4, which includes high-friction material 6 and vacuum ports 7, comes between vacuum chamber 2 and restraint belts 3, the top document is cupped. This is effected by cupping rims 5 and the vacuum which serve to pull it free from the next succeeding document.

After the top document is pulled against porting sector 4, the combination of material 6 and the vacuum pulls the document through the belts 3 area and feeds it into a document transport. The cupping action and belts 3, which run in a direction opposite to that of drum 1, prevent the second document from being fed concurrently with the first document. As porting section 4 passes the end of chamber 2, the vacuum is cut off and drum 1 revolves for another cycle.
