Claim 16:
17. An apparatus for use in erecting a carton, comprising:
a shuttle having a bed with a horizontally extending base having a base gripper;
a shuttle drive apparatus for driving said shuttle in a horizontal advancement direction;
an end effector having an end effector gripper;
an end effector movement device for moving said end effector;
a controller operatively associated with said shuttle drive apparatus, said end effector movement device and said base gripper and said end effector gripper, and configured to:
operate said movement device and end effector to grip a top side panel of a knock-down carton blank and place said knock-down carton blank on said horizontally extending base of said shuttle such that a bottom side panel of said knock-down carton blank abuts said horizontally extending base;
activate said base grippers to grip said bottom side panel of said blank;
operate said movement device to raise said top side panel of said knock-down carton blank with said end effector while providing relative horizontal movement between said movement device and said shuttle in order to open said knock-down carton blank into a carton sleeve;
wherein a side panel is pivotally connected to said top side panel and to said bottom side panel of said carton blank;
wherein said controller is operable to operate said movement device to raise and open said knock-down blank so that said side panel is brought into abutment with a generally vertically extending back portion of said shuttle, and said controller is further operable such that after said raising, a gripper of said back portion grips said side wall of said knock-down carton blank;
wherein said controller is further operable such that while the gripper of said back portion grips said side panel of said knock-down carton blank, the gripper of the end effector releases said top side panel of said knock-down carton blank.
