Self Centering Forms Stacker Tray Assembly

This self-centering forms stacker tray assembly comprises movable support plate 1 which slides on fixed lower support plate 2 for a predetermined distance. Cable pulleys 3 are mounted on plate 2. The ends of cables 4 are clamped to plate 1.

Inner rack 5 slides on guide rails 6 and is connected with cables 4. Thus rack 5 is moved by an amount which is equal and opposite in direction when plate 1 is moved. Outer rack 7 is mounted to plate 1 through the use of extension plate 8. The latter can be moved from a latched or detented normal position in relation to plate 1.

Rack 5 in conjunction with rack 7, maintains vertical alignment of the tray assembly in order to permit automatic adjustment when rack 7 is moved. Forms with a folded length between 4 and 18 inches can be stacked with the inner and outer folded edges centered in relationship to the forms path through the stacker drive rolls.

Forms with a folded length of between 3.25 and 4 inches or 18 and 24 inches can be aligned by repositioning rack 7 in relation to plate 1.

The complexity of adjusting the stacker tray and racks of a printer device is reduced. Stacking failures resulting from incorrect adjustments are eliminated.
