Abstract
There is provided an apparatus for processing sheets. The apparatus comprises a feeding zone, a discriminating zone, a sorting zone and a stacking zone. The feeding zone includes rollers and guides for taking out sheets one at a time from a group of sheets in the stacked state and feeding them into a conveyor path. The discriminating zone includes a plurality of sensors for detecting positions, a magnetic pattern and a photo-pattern to discriminate the sheets. The sorting zone includes angularly rotatable forks for sorting the sheets according to their kinds in response to the signals from the discriminating zone. The stacking zone includes containers for stacking the sheets sorted by the sorting zone.
Claims7
An apparatus for processing sheets which comprises:
- means for feeding sheets one at a time from a stack of sheets;
- conveyor means for receiving the sheets from said feeding means and for moving the sheets along a conveyor path;
- detecting means comprising a plurality of sensors disposed in said conveyor path for detecting widths of the sheets and for generating signals representative of the sensed widths, for detecting whether the obverse side of the sheet is up and for generating a signal indicative of the sensed sheet side, and for detecting a sheet that cannot be discriminated and for generating a signal indicative of the sheet indiscrimination;
- discriminating means electrically associated with said detecting means for discriminating the sheets into a plurality of groups, one group having sheets of a set kind with the obverse side up, another group having sheets of the set kind with the reverse side up, a third group having sheets of different kinds, and a fourth group having sheets that cannot be discriminated, and for generating signals indicative of said groups in response to a combination of signals from said detecting means;
- sorting means disposed downstream of said detecting means in said conveyor path for sorting the sheets into said groups of sheets in response to said signals from said discriminating means;
- and
- stacking means for stacking the sheets sorted by said sorting means.
