Document imaging system and method for imaging documents to convey documents without entraining documents
A system is provided for processing documents. In particular, the system incorporates a feeder for feeding documents to a device for further processing of the documents. For instance, the system finds particular application in the field of document imaging in which a variety of documents of varying sizes and orientation are to be fed to an imaging system, such as a document scanner. The system may provide a sorting station that receives documents from a workstation and sorts the documents to a plurality of sort locations. The system may export the image data for the documents to a fileserver so that a remote operator can provide instructions for the processing of the documents so that the documents can be subsequently processed according to the instructions provided by the operator.
1. An apparatus for processing documents, comprising:
a conveyor for receiving documents, wherein the conveyor is configured to convey documents along a document path without entraining the documents;
a plurality of output locations configured to receive documents from the conveyor;
a sorter for sorting documents to the output locations, wherein the sorter comprises:
a first set of ejectors configured to displace documents on the conveyor transverse the document path, wherein ejectors in the first set of ejectors are positioned to eject documents toward a first one of the output locations;
a displaceable stop operable to selectively stop documents along the document path;
a first rotatable cam;
a second rotatable cam;
a first cam follower connected with the displaceable stop such that rotation of the first cam operates to raise the ejector;
a second cam follower connected with one of the ejectors such that rotation of the second cam operates to raise the ejector;
a shaft connected with the first and second cams so that the shaft is operable to rotate the first and second cams, wherein the first cam is configured and positioned on the shaft such that rotation of the shaft by a first angular amount raises the stop without raising the ejector and wherein rotation of the shaft by a second amount raises the ejector.
2. The apparatus of claim 1 wherein the displaceable stop is displaceable between a first position in which the stop is positioned below an upper surface of the conveyor and a second position in which the stop is positioned above the upper surface.
3. The apparatus of claim 2 wherein the displaceable stop is positioned adjacent the first set of ejectors.
4. The apparatus of claim 1 wherein each of the ejectors of the first set of ejectors comprises a belt assembly operable to engage documents.
5. The apparatus of claim 1 comprising a second set of ejectors configured similar to the first set of ejectors, wherein the second set of ejectors is spaced from the first set of ejectors and wherein each ejector in the second set of ejectors is configured to displace documents toward a second one of the output bins.
6. The apparatus of claim 5 wherein the controller is configured to selectively operate the first or second set of ejectors to direct documents to the first or second output bin based on criteria other than the detected characteristic that is indicative of the length of the document.
