Cartoning apparatus for packaging sealed bags containing loosely packed discrete articles in board cartons comprises a carton transfer and erecting mechanism which withdraws a collapsed carton sleeve from a magazine and deposits it in erected condition on a carton conveyor which advances the erected carton sleeve with step-by-step motion through a pluraltiy of work stations. A form, fill and seal machine delivers a sealed bag containing a product to a vacuum conveyor which accelerates the bag through a guide shroud and into the near open end of an associated carton sleeve supported on the carton conveyor at a carton filling station. A rail disposed at the far open end of the associated carton sleeve arrests the bag within the sleeve. The carton conveyor advances the carton sleeve and bag to further work stations where the carton end flaps are closed and sealed. Another embodiment of the invention utilizes a vacuum head at the filling station adjacent the far open end of the associated sleeve to draw vacuum on the interior of the sleeve and thereby assist movement of a bag into the carton sleeve.
A cartoning machine comprising a carton conveyor, carton confining receptacles carried by said carton conveyor, drive means for advancing said carton conveyor to move each successive carton confining receptacle to and through a plurality of stations including a carton receiving station and a carton filling station, carton transfer means for depositing an erected carton sleeve in each successive carton confining receptacle at said carton receiving station, bag guiding means disposed laterally of said carton conveyor at said filling station for directing a filled bag into the near open end of an associated carton sleeve at said carton filling station, bag transfer means for moving a bag through said bag guiding means and feeding it into said carton through said open end, means for delivering a bag to said bag transfer means, and vacuum means for assisting movement of a bag through said guiding means and from said bag guiding means into the associated carton sleeve and including a vacuum head mounted adjacent said carton conveyor at said carton filling station and at the laterally opposite side of said carton conveyor from said bag guiding means for engaging the carton sleeve at its far open end to draw a vacuum on the interior of said carton sleeve.
