ABSTRACT:
A high speed feeder for cartons being fed into a cartoner includes both mechanical and fluid flow environments for precisely delivering cartons. A preferably inclined conveyor receives cartons stacked on their edges and in a generally vertical orientation. A rotating metering wheel at the downstream end of the conveyor engages the top edges of the cartons and separates them one at a time from the incoming stack. A blower is provided to direct air onto the cartons adjacent the metering wheel to (a) blow the cartons against the metering wheel, (b) blow air between the first and second cartons of the stack as the metering wheel separates the first from the second, and (c) blow the cartons down to a horizontal attitude. Horizontal feed chains having feed lugs receive the horizontal cartons and advance them one at a time into the cartoner. Vacuum nozzles are provided to aid in controlling carton placement on the feed chains and lugs throughout a broad range of feed speeds. Methods are included.
