Super Ion Air Knife Removes Foil Dots In Lid Cutting Operation

In a food manufacturer about a packaging line they were having issues with.  The plant fills continuous rows of thermo-formed cups which is then sealed with a single foil lid. Once sealed, a machine cuts the row to separate the cups, which creates small scrap pieces of foil. After the cutting operation, they try to collect as much of the waste trim as possible but some small pieces of foil, they call “dots”, cling to the surface of the cup and cutter due to static charge.  The company installed a vacuum collection hood in this area, to try and help keep the foil pieces or any dust from falling onto the cup during the process. While this did help somewhat, some dots would remain and eventually fall off further down the line, making small piles that needed to be manually cleaned to avoid potential jams, which slowed down their production cycle.

The cups are filled and separated on a 44″ wide, mesh-screen conveyor with individual lanes to process multiple rows of cups. After being cut, the cups are moved to the inspection area and then packaged for shipment.  I recommended they mount a 48″ Super Ion Air Knife above and below the cups and direct the airflow to the end where the vacuum collection hood is located. The idea is, as the ions eliminate the charge, the small foil dots will release and the laminar airflow would keep the parts moving toward the vacuum hood, thus removing all foil trim and preventing any piling of trim further down the production line.
