Patent

CA 2182472

Apparatus (200) for opening the closure flaps (22-25) of a carton (12), for presenting the carton (12) for loading, and for closing the closure flaps (22-25) is disclosed including a carrier (202) which initially receives the carton (12). The carrier (202) carries the carton (12) into a carriage (226), with the carton (12) sandwitched therebetween. The closure flaps (22-25) are opened by a device (242) including fingers (254-257) which are pivoted to an expanded position after their insertion through an opening (27) in the closure flaps (22- 25). An elevator (212) raises the carton (12) in the carriage (226) while the carton (12) is still under compression, with suction cups (56, 171-173) then being attached to the closure flaps (22-25). The carriage (226) can then be moved to a loading position and back where the closure flaps (22-25) of the loaded carton (12) are fan folded by a device (120). The elevator (212) can then be lowered where the closed carton (12) can be pushed therefrom.

Appareil (200) pour l'ouverture des volets de fermeture (22-25) d'un carton (12), la présentation de ce dernier (12), son chargement, et la fermeture desdits volets de fermeture (22-25). Ledit appareil comporte un transporteur (202) qui reçoit initialement le carton (12), et transporte le carton (12) dans un chariot (226), le carton étant pris en sandwich entre ces derniers. Les volets de fermeture (22-25) sont ouverts par un dispositif (242) doté de doigts (254-257) qui pivotent de manière à se trouver dans une position étendue une fois insérés par une ouverture (27) dans les volets de fermeture (22-25). Un élévateur (212) monte le carton (12), toujours en compression, dans le chariot (226), des ventouses (56, 171-173) étant ensuite fixées auxdits volets de fermeture (22-25). Le chariot (226) peut ensuite être mis en position de chargement et revenir dans la zone où les volets de fermeture (22-25) du carton chargé (12) sont repliés en accordéon par un dispositif (120). L'élévateur (212) peut alors être abaissé, et le carton fermé (12) peut être enlevé de celui-ci.
