Collator

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

The 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 10 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 having upper guide plate 16. The entry of a sheet into a bin is detected, by means not shown, and deflector indexing mechanism 16A is controlled to step deflector 15 and its guide plate 16 down to the next bin, where it awaits the arrival of the next sheet. '

Fig. 2 shows the vertical conveyor, 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, and is as long as the longest sheet, i.e., 14 inches. The sheets are picked off belts 17 and 18 by the deflector 15 and then enter a selected bin as the sheet passes between the deflector and the upper guide plate 16. The two belts are asymmetrically located rel...
