Abstract

Claims (32)

1 . An apparatus for use in erecting a first case from a first knock-down blank having a first length L1 and after erecting said first case, erecting a second case from a second knock-down blank having a second length L2 that is a different length than L1, said apparatus comprising:

a knock-down blank feeding apparatus operable to feed a first knock down blank and a second knock down blank to a pick up station;

a shuttle having a bed with a horizontally extending base having base grippers;

shuttle drive apparatus for driving said shuttle in a horizontal advancement direction;

an end effector having end effector grippers;

an end effector movement device for moving said end effector;

a movable edge guide;

a controller operatively associated with said movable edge guide, said shuttle drive apparatus, said end effector movement device and said grippers and configured to:

operate said feeding apparatus to feed a first knock down blank to a pick-up position in which a leading edge abuts said movable edge guide;

operate said movement device and said end effector to grip a top side panel of said first knock-down carton blank and move said first knock down blank and place said first knock-down carton blank on said horizontally extending base of said shuttle such that a bottom side panel of said first knock-down carton blank abuts said horizontally extending base;

activate said base grippers to grip said bottom side panel of said first knock-down blank;

operate said movement device to raise said top side panel of said first knock-down carton blank with said end effector while horizontally advancing said shuttle in order to open said first knock-down carton blank into a first carton sleeve;

adjust the position of said movable edge guide;

operate said feeding apparatus to feed a second knock down blank to a pick-up position in which a leading edge abuts said movable edge guide;

operate said movement device and said end effector to grip a top side panel of said second knock-down carton blank and place said second knock-down carton blank on said horizontally extending base of said shuttle such that a bottom side panel of said second knock-down carton blank abuts said horizontally extending base;

activate said base grippers to grip said bottom side panel of said second knock-down blank;

operate said movement device to raise said top side panel of said second knock-down carton blank with said end effector while horizontally advancing said shuttle in order to open said second knock-down carton blank into a second carton sleeve.

2 . The apparatus of claim 1 wherein said bed has an upstanding back wall having back wall grippers, said controller is operatively associated with said back wall grippers, and said controller is further configured to operate said back wall grippers to sequentially grip a further side panel of said first carton sleeve and a further side panel of said second carton sleeve.

3 . The apparatus of claim 2 wherein said controller is further configured to, after operating said back wall grippers to grip said further side panels, operate said end effector to sequentially release said top side panels.

4 . The apparatus of claim 3 further comprising a pair of horizontally reciprocating ploughs disposed beside said bed and wherein said controller is further configured to, after releasing said top side panel of said knock-down carton blank, advancing said pair of horizontally reciprocating ploughs toward one another to fold minor end flaps of said carton sleeve inwardly toward one another.

5 . Apparatus for use in erecting a carton, comprising:

a shuttle having a bed with a horizontally extending base having base grippers;

shuttle drive apparatus for driving said shuttle in a horizontal advancement direction;

an end effector having end effector grippers;

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 grippers 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 horizontally advancing said shuttle in order to open said knock-down carton blank into a carton sleeve.

6 . The apparatus of claim 5 wherein said bed has an upstanding back wall having back wall grippers, said controller is operatively associated with said back wall grippers, and said controller is further configured to operate said back wall grippers to grip a further side panel of said carton sleeve.

7 . The apparatus of claim 6 wherein said controller is further configured to, after operating said back wall grippers to grip said further side panel, operate said end effector to release said top side panel.

8 . The apparatus of claim 6 further comprising a pair of horizontally reciprocating ploughs disposed beside said bed and wherein said controller is further configured to, after releasing said top side panel of said knock-down carton blank, advancing said pair of horizontally reciprocating ploughs toward one another to fold minor end flaps of said carton sleeve inwardly toward one another.
