  • Patent number: 5653671
    Abstract: A carton feeder assembly is positioned substantially at the infeed conveyor level and includes a carton supply assembly, a carton selector, a carton opener, and a carton erector. The carton supply assembly has a carton supply position, a carton holding position, and a carton selecting position. The carton selector includes a pair of feeder wheels with corresponding suction devices and respective motion defining assemblies. The motion defining assemblies cause the suction devices to move along a linear pick line as the feeder wheels rotate, so that the suction devices can apply a suction on a carton to be selected. The selected carton is brought into contact with the feeder wheels by retraction of the suction devices caused by respective motion defining assemblies, so that the carton moves with the feeder wheels to the carton opener.

  • Patent number: 5558614
    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.

  • Patent number: 5531661
    Abstract: A method and means for opening a collapsed rectilinear carrier sleeve. As the collapsed sleeve is moved through a packaging machine it is partially opened so that the leading panel extends at an angle to the horizontal. A continuous upward force is then delivered to the leading panel to cause the leading panel to pivot up about its upstream fold line until it reaches the vertical. The collapsed sleeve is partially opened by elevating side flaps connected to an upper panel to cause the upper panel to be elevated. One way of accomplishing this is to cause the upper flaps to ride up over a fixed cam surface while lower flaps connected to a lower panel move under the cam to prevent the lower panel from moving in an upward direction.

During manufacture, paper bags are guided horizontally through the machine by a conveyor forming part of the machine. With this arrangement, one of the suction wheels is placed under the bag, and the other wheel is placed over the bag in line. As each bag is moved by the conveyor, both suction wheels are brought into motion like a rolling operation. Each wheel has a shaft with a hollow channel going to a suction cup at the periphery of the wheel. The number of suction cups around the circumference of the wheel could be any amount. In a preferred embodiment, there are 12 equally spaced suction cups. A vacuum pump with a hose is connected onto the shaft. The pump draws air through the channel which comes from a suction cup so that, when the bag comes into the vicinity of the suction cup, the cup sticks on the bag layer.

  • Patent number: 4250684
    Abstract: Apparatus is provided for packing articles, for example apples and other readily damaged fruits, in expanded slices of honeycomb using a conveyor on which the honeycomb is fitted, and carried through a filling station to an unloading station.Means are provided for expanding the slices of honeycomb and applying them to the conveyor in turn. A preferred arrangement is to supply the unexpanded slices one by one from a magazine and accelerate each slice so that it is projected into position for engagement by vacuum cups of an expansion device. Having been expanded, the slices are fitted to the conveyor where they are held in the expanded state by attachment devices provided thereon.At the unloading station, the packages of articles are removed from the conveyor for stacking in a confining carton while confining them in the horizontal direction to retain the position of articles packaged in incomplete cells.
