Cam operated document stop for high speed item sorter

摘要

A cam operated document stop in an item sorter provides positive action to halt the passage of a document or other item, from a flow of documents in a mainstream pathway, when it arrives in an inspection station. The document is stopped in an open receptacle area for inspection and then released for return to the mainstream pathway. Stoppage is effected by rotation of cam members which position a stop arm to stop the flow of the document. After the document has been inspected and corrected, the stop arm is repositioned to release the document into the mainstream flow. After a suitable delay to allow the document to clear the receptacle area, the cam members rotate the stop arm into position to stop the next document.
