Collator

This collator accepts variable-length sheets and includes a damping assembly to prevent end flutter of long sheets.

e output of a printer or copier is accepted at collator input 10. The printed sheets are oriented with the narrow width dimension parallel to the direction of sheet travel, and with the long length dimension normal to the direction of sheet travel. This length dimension varies from 8 to 14 inches.

The sheets travel on conveyor 12 over the top of a horizontal stack of sheet receiving bins 11. A guide 13 transfers the sheets to a vertical vacuum conveyor
14. As the sheets travel down the vertical conveyor, they are selectively deflected into a bin by vertically movable deflector 15. The entry of a sheet into a bin is detected, by means not shown, and deflector indexing mechanism 16 is controlled to step deflector 15 down to the next bin, where it awaits the arrival of the next sheet.

Fig. 2 shows the vertical conveyor 14, as seen from the side facing the bins
11. This conveyor includes two vacuum belts 17 and 18; that is, the sheets are held against the belts by vacuum force. Deflector 15 is notched to allow passage of the belts 17 and 18, and is as long as the longest sheet, i.e., 14 inches. The two belts are asymmetrically located relative to the center of the deflector 15. Thus a sheet having a 10 inch length is transported as shown by outline 19. A 14-inch sheet is transported as shown by extended outline 20.
