Abstract

A travelling gate sorter in which the feed throat (gate) is formed at the exit 4 of a transport formed by a pair of nipping belts 1, 2 and the exit is indexed past the bins 3. By virture of the flexibility of the belts this may be achieved while maintaining a fixed input 5 to the belt transport. By suitable tensioning means - rollers 6, 7 - along the two belts the path of the feed throat 4 may follow a predetermined line corresponding to the positions of the bins. Thus, as shown in the drawing, the belts move progressively from the configuration shown in full lines, where the throat 4 is opposite the uppermost bin, to the position shown in broken lines where the throat 4 is opposite the lowermost bin. Variations in the operating runs of the belts are accommodated by the movement of the tensioning rollers 6, 7 between their full and broken line positions.

TWIN BELT FEED THROAT FOR SORTER (Cont'd)

A travelling gate sorter in which the feed throat (gate) is formed at the exit 4 of a transport formed by a pair of nipping belts 1, 2 and the exit is indexed past the bins 3. By virture of the flexibility of the belts this may be achieved while maintaining a fixed input 5 to the belt transport. By suitable tensioning means - rollers 6, 7 - along the two belts the path of the feed throat 4 may follow a predetermined line corresponding to the positions of the bins. Thus, as shown in the drawing, the belts move progressively from the configuration shown in full lines, where the throat 4 is opposite the uppermost bin, to the position shown in broken lines where the throat 4 is opposite the lowermost bin. Variations in the operating runs of the belts are accommodated by the movement of the tensioning rollers 6, 7 between their full and broken line positions.

With this arrangement, the sheets are gripped firmly between the two belts 1, 2 so that no other gripping system (e.g., vacuum) is required.

The proposal may be applied to a horizontal or a vertical sorter.
