Document Type and Number:
WIPO Patent Application WO1995022492
Kind Code:
A3
Abstract:
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) sandwiched 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.
