Active tamper for bidirectional sorter

Claim 2

In a multi-bin sorter with means for sequentially feeding a sheet of paper or the like in a sheet feeding path from a fixed sheet output such as a copier or printer sequentially into one said bins adjacent thereto, and wherein said bins are reciprocally indexable in two directions relative to said fixed sheet output, to accumulate stacked sheet sets in respective said sorter bins, and further including a sheet edge alignment registration jogging system, the improvement wherein said sheet edge alignment registration jogging system comprises tamping means for tamping those sheets which are in said sorter bins which are above and below said one said bin adjacent to said fixed sheet output into which a sheet is being so fed without interfering with said feeding of a sheet into said one said bin, wherein said tamping means is stationarily mounted and comprises a tamping member extending alongside said sorter bins which are above and below said one said bin adjacent to said fixed sheet output, which tamping member is intermittently movable into those bins for tamping sheets therein towards a registration position but is configured such that it does not extend into said sheet feeding path and does not tamp sheets in said one said bin adjacent to said fixed sheet output.

Claim 3

The multi-bin sorter of claim 1, wherein said tamping member is a pivotally rotated, generally vertical, centrally apertured, resilient, light weight, large area flag shaped flapper.

Claim 4

The multi-bin sorter of claim 2, wherein said tamping means jogs sheets which are in said sorter bins which are above and below said one said bin adjacent to said fixed sheet output into a corner stapling registration position in said bins.

Claim 5

The multi-bin sorter of claim 1, wherein said bins are vertically inclined from the horizontal to provide two-axis corner sheet registration with a single said tamping means tamping substantially on one axis.

Claim 6

The multi-bin sorter of claim 4 wherein said bins have two differently vertically inclined bin surface portions with the bin surface portion furthest from said fixed sheet output having the greater said vertical inclination.

Claim 7

In a multi-bin sorter with means for sequentially feeding a sheet of paper or the like in a sheet feeding path from a fixed sheet output such as a copier or printer sequentially into one said bins adjacent thereto, and wherein said bins are reciprocally indexable in two directions relative to said fixed sheet output, to accumulate stacked sheet sets in respective said sorter bins, and further including a sheet edge alignment registration jogging system, the improvement wherein said sheet edge alignment registration jogging system comprises tamping means for tamping those sheets which are in said sorter bins which are above and below said one said bin adjacent to said fixed sheet output into which a sheet is being so fed without interfering with said feeding of a sheet into said one said bin, wherein said tamping means is stationarily mounted adjacent said fixed sheet output and comprises a tamping member extending alongside said sorter bins which are above and below said one said bin adjacent to said fixed sheet output, which tamping member is intermittently movable into those bins for tamping sheets therein towards a registration position but is configured such that it does not extend into said sheet feeding path and does not tamp sheets in said one said bin adjacent to said fixed sheet output by said tamping member having two active tamping surface portions separated by a central missing portion.

Claim 8

In a multi-bin sorter with means for sequentially feeding a sheet of paper or the like in a sheet feeding path from a fixed sheet output such as a copier or printer sequentially into one said bins adjacent thereto, and wherein said bins are reciprocally indexable in two directions relative to said fixed sheet output, to accumulate stacked sheet sets in respective said sorter bins, and further including a sheet edge alignment registration jogging system, the improvement wherein said sheet edge alignment registration jogging system comprises tamping means for tamping those sheets which are in said sorter bins which are above and below said one said bin adjacent to said fixed sheet output into which a sheet is being so fed without interfering with said feeding of a sheet into said one said bin, wherein said tamping means is stationarily mounted adjacent said fixed sheet output and comprises a tamping member extending alongside said sorter bins which are above and below said one said bin adjacent to said fixed sheet output, which tamping member is intermittently movable into those bins for tamping sheets therein towards a registration position but is configured such that it does not extend into said sheet feeding path and does not tamp sheets in said one said bin adjacent to said fixed sheet output by said tamping member having two active tamping surface portions separated by a central missing portion.

Claim 9

The multi-bin sorter of claim 6, wherein said tamping member is a piovotally rotated, generally vertical, centrally apertured, resilient, light weight, large area flag shaped flapper.
