A method for on-the-fly detection and separation of multiple checks or like documents transported in a track, wherein the documents are first subjected to twin opposed vacuum forces from a suction source, to separate multiple documents; then a measuring and analysis of the resulting pressure differentials is taken within the vacuum-forming system; the system being provided with a cyclonic filter-separator upstream of the suction source, for removing a storing dust and debris entrained within the vacuum-forming air flow; the cyclonic filter-separator being designed to provide constant vacuum-forming airflow regardless of the nature or quantity of debris removed and collected; the system also being provided with a pressure sensor to give clear indication of the separated/unseparated state of the passing documents, and to exhibit a variable damping accessory.
A technique for differentiating and separating multiple overlapped like documents from single like items, transported along track means, wherein said documents are first subjected to opposed vacuum forces from suction means to separate them at a separation-station, and wherein the state of the documents, whether single or multiple, is then determined by measuring and analyzing the resulting pressure differentials within suction system;
In an item processing apparatus with a station for separating multiple planar items from single like items, which are transported along a track past a separation site where the items are subjected to vacuum forces supplied from a prescribed vacuum-generating system, the improvement therewith of cyclonic filter/suction pump means coupled to said site and adapted for removing and storing dust and debris entrained within the vacuum-forming air flow, this cyclonic pump filter/station means providing a constant vacuum-airflow regardless of the nature or quantity of debris removed and collected;
In a separation array for separating multiple, possibly-overlapped items transported along track means of an item processing apparatus;
In an item processing apparatus including separation means for separating multiple like items from one another as they are transported along a track, said separation means subjecting the items to opposed vacuum forces from a vacuum-generating suction system, which includes suction means to generate the underpressure/vacuum forces, the improvement therewith, supplementing this suction means, of cyclonic separator means to help generate said vacuum forces and to help provide a constant vacuum-airflow regardless of the nature or quantity of debris in the airflow or whether any debris is to be removed at all.
In a separator apparatus for detection and separation of multiple like, planar items transported along a track of an item processor, said apparatus including vacuum means where the items are subjected to vacuum forces from a suction source of a vacuum-generator system, the combination therewith of cyclonic separator means upstream of said suction source, for helping to provide constant vacuum-forming airflow regardless of the nature or quantity of any debris to be removed, if any.
In a separator apparatus for differentiating and separating multiple overlapped like items from single like items, transported along track means, said apparatus including a suction station where said items are subjected to vacuum forces from suction means, wherein;
