Document Aligner

In a document aligner the documents are dropped vertically in their plane into a gutter 1 and are horizontally transported in an upright position to the right, into a document handling machine, by a transport wheel 2 cooperating with a spring-loaded swivel wheel 3.

The swivel wheel or castor 3 brings about the aligning function as a mass 4 tries to turn the document clockwise, while the transport wheel 2 holds it horizontal. The transport wheel 2 has several flat portions, e.g., four, at its circumference which, during brief intervals, cause a decrease in the normal force exercised by the spring-loaded swivel wheel 3, with the result that, in these intervals, the aligning function will prevail, whereas in the intervals that the circular circumferential parts engage the swivel wheel, the transport function prevails. This construction keeps the spring load on the swivel wheel low enough to prevent over-aligning (the curling up of the edge of a sheet against the aligning edge) or damage to the document.
