Automatic cartonning apparatus comprising a conveyor which is advanced at intermittent intervals a predetermined distance, the apparatus being provided with means operable following conveyor advance to withdraw a single carton blank from a stack of carton blanks and open same up to a set up condition ready to receive a plurality of articles on the conveyor at a first position, the carton in said set up condition having a closed bottom and open top end and side flaps, the apparatus further being provided with means for guiding articles into a set up carton at a second carton loading position displaced along the conveyor path a whole multiple of said predetermined distance from said first position, means operable following conveyor advance for closing the carton end flaps at a third carton flap closing position displaced along the conveyor path a whole multiple of said predetermined distance from said second loading position, means for closing the carton side flaps subsequently to the closing of the end flaps and control means for controlling the conveyor such that the event of conveyor advance is adapted to be related to the completion of the filling of a set up carton at the carton loading position.
An automatic cartonning apparatus comprising a conveyor, means for advancing said conveyor a predetermined distance, means operable following conveyor advance to withdraw a single carton blank from a stack of carton blanks and open same up to a set up condition ready to receive a plurality of articles on said conveyor at a first position, said carton in said set up condition having a closed bottom and open top end and side flaps, means for guiding articles into a set up carton at a second carton loading position displaced along the conveyor path a whole multiple of said predetermined distance from said first position, means operable following conveyor advance for closing the carton end flaps at a third carton flap closing position displaced along the conveyor path a whole multiple of said predetermined distance from said second loading position, means for closing the carton side flaps subsequently to the closing of the end flaps and control means for said conveyor advancing means, said means for withdrawing and setting up a carton on said conveyor comprising reciprocal suction means operable in one direction for engaging the leading side panel of the foremost blank of a stack of carton blanks displaced from the path of said conveyor and operable in the opposite direction to first draw said leading side panel away from said stack and towards the conveyor to initiate the opening out of the carton blank towards the set up condition and to subsequently draw the set up carton onto the conveyor at said first position, and means for effecting displacement of an end panel of the blank in a direction transversely of the direction of the side panel movement as same is being drawn towards the conveyor to complete the carton set up.
An automatic cartonning apparatus comprising a conveyor, means for advancing said conveyor a predetermined distance, means operable following conveyor advance to withdraw a single carton blank from a stack of carton blanks and open same up to a set up condition ready to receive a plurality of articles on said conveyor at a first position, said carton in said set up condition having a closed bottom and open top end and side flaps, means for guiding articles into a set up carton at a second carton loading position displaced along the conveyor path a whole multiple of said predetermined distance from said first position, means operable following conveyor advance for closing the carton end flaps at a third carton flap closing position displaced along the conveyor path a whole multiple of said predetermined distance from said second loading position, means for closing the carton side flaps subsequently to the closing of the end flaps and control means for said conveyor advancing means whereby the event of conveyor advance is adapted to be related to the completion of the filling of a set up carton at said second carton loading position, said means for advancing said conveyor said predetermined distance comprising an oil operated cylinder driven by compressed air.
An automatic cartonning apparatus comprising a conveyor, means for advancing said conveyor a predetermined distance, means operable following conveyor advance to withdraw a single carton blank from a stack of carton blanks and open same up to a set up condition ready to receive a plurality of articles on said conveyor at a first position, said carton in said set up condition having a closed bottom and open top end and side flaps, means for guiding articles into a set up carton at a second loading position displaced along the conveyor path a whole multiple of said predetermined distance from said first position, means operable following conveyor advance for closing the carton end flaps at a third carton flap closing position displaced along the conveyor path a whole multiple of said predetermined distance from said second loading position, means for closing the carton side flaps subsequently to the closing of the end flaps and control means for said conveyor advancing means, said means for advancing said conveyor, withdrawing a carton blank and closing the carton end flaps all being fluid operated means, and said control means comprising a motor adapted to be energized in response to an external signal, a cam shaft driven by said motor, a plurality of cams on said cam shaft, a control valve associated with each of said fluid operated means, each control valve being arranged to be operated by a respective one of said cams on said cam shaft, and means operated by another of said cam on said cam shaft for de-energizing said motor upon completion of a cycle of operation of said apparatus and preparatory to said motor receiving a subsequent external signal.
