Paper Inserter and Stacker Bin

This bin includes integral drive belts which insert and stack the individual sheets in the bin.

Printed sheet 1 travels down transport belt 2 until it reaches the position of sheet deflector 3. At this position the sheet is diverted to bin 4.

The sheet enters entrance nip 5 between driven belt 6 and idler belt 7, as the leading edge of the sheet 1 leaves the deflector 3. Belt 6 has a rough outer surface, for example a cog pattern, and is driven by serpentine belt 8.

Belt 6 is driven slightly faster than transport belt 2. As the sheet's leading edge leaves belts 6-7, it is deflected downward by spring 9. Thereafter its leading edge strikes free swinging and weighted stabilizer bar 10, which bar is pivoted at 11. The sheet 1 then slides under the bar and stops with its leading edge adjacent impact bar 12.

The distance between impact bar 12 and the exit nip 13 formed by belts 6 and 7 is less than the similar sheet dimension. Thus, the sheet's trailing edge is still under the influence of belts 6 and 7 when its leading edge engages the impact bar. As a result, the sheet buckles and its trailing edge is urged, by spring 9 and its own inherent buckle, into the surface texture of belt 6. As a result, the trailing edge is driven by belt 6's surface such that the sheet's trailing edge is stacked in alignment at 14. Dotted line 17 shows the sheet 1 in a buckled condition.

Stripping plate 15 aids in releasing the sheet's trailing edge from bel...
