Claims
- 1. A method of applying adhesive to a container moving along a conveying path, the method comprising:
turning first and second adhesive dispensing guns on to dispense adhesive to a surface of the container while the container is moving along the conveying path; pivoting the first and second adhesive dispensing guns about at least one axis parallel to the conveying path to thereby apply the adhesive to the container along a direction generally perpendicular to the conveying path; and stopping the flow of adhesive from the first and second adhesive dispensing guns.
- 2. A method of applying adhesive to respective first and second major flaps and first and second minor flaps of a container in a siftproof pattern, the method comprising:
moving the container along a conveying path, said major flaps being folded in an outwardly extending position and said minor flaps being folded in an inwardly extending position; moving a first dispensing gun relative to the container while dispensing a first bead of adhesive therefrom along respective first edges of the first major flap and the first minor flap in a direction generally perpendicular to the conveying path; stopping the dispensing of the first bead of adhesive; moving a second dispensing gun relative to the container while dispensing a second bead of adhesive therefrom along the first edge of the second major flap and the first minor flap in a direction generally perpendicular to the conveying path; stopping the dispensing of the second bead of adhesive; dispensing a third bead of adhesive from a third dispensing gun along a free edge of the second major flap along a direction generally parallel to the conveying path; stopping the dispensing of the third bead of adhesive; moving the first dispensing gun relative to the container while dispensing a fourth bead of adhesive therefrom along the second edge of the first major flap and the folded edge of the second minor flap in a direction generally perpendicular to the conveying path; stopping the dispensing of the fourth bead of adhesive; moving the second dispensing gun relative to the container while dispensing a fifth bead of adhesive therefrom along the second edge of the second major flap and folded edge of the second minor flap in a direction generally perpendicular to the conveying path; and stopping the dispensing of the fifth bead of adhesive.
- 3. The method of claim 2, wherein the steps of moving the first dispensing gun includes pivoting the gun about an axis generally parallel to the conveying path.
- 4. The method of claim 2, wherein the steps of moving the second dispensing gun includes pivoting the gun about an axis generally parallel to the conveying path.
- 5. The method of claim 2, wherein the first and second guns are moved simultaneously to dispense adhesive to the flaps.
- 6. A method of applying adhesive to respective first and second major flaps and first and second minor flaps of a container in a siftproof pattern, the method comprising:
moving the container along a conveying path, said major flaps being folded in an outwardly extending position and said minor flaps being folded in an inwardly extending position; moving first and second adhesive dispensing guns relative to the container to dispense first and second adhesive beads along first and second side edges of the first major flap and along portions of the first and second minor flaps; stopping the dispensing of the first and second adhesive beads; moving the first and second adhesive dispensing guns relative to the container to dispense third and fourth adhesive beads along first and second side edges of the second major flap and along portions of the first and second minor flaps; stopping the dispensing of the third and fourth adhesive beads; dispensing a fifth bead of adhesive from a third dispensing gun along a free edge of the second major flap along a direction generally parallel to the conveying path; and stopping the dispensing of the fifth bead of adhesive.
- 7. The method of claim 6 wherein the steps of moving the first and second guns relative to the container include linearly moving the guns along a direction that is oblique to the conveying path.
- 8. An apparatus for dispensing adhesive to major and minor flaps of a container to form a siftproof seal, comprising:
a conveyor adapted to move a container along a conveying path; first and second adhesive dispensing guns supported above said conveyor and movable to apply adhesive beads to respective major and minor flaps of the container along directions generally perpendicular to the conveying path; at least one motor associated with said first and second guns and adapted to move said guns to thereby apply the adhesive along directions generally perpendicular to the conveying path; and a third adhesive dispensing gun supported above said conveyor and adapted to apply an adhesive bead to a major flap along a direction generally parallel to the conveying path.
- 9. The apparatus of claim 8, wherein said first and second guns are pivotable about at least one axis parallel to the conveyor path.
- 10. The apparatus of claim 8, wherein said first and second adhesive dispensing guns are movable in directions parallel and perpendicular to the conveying path.
- 11. The apparatus of claim 8, wherein each of said first and second dispensing guns is associated with a separate motor.
- 12. The apparatus of claim 8, wherein said first and second guns are linearly movable along a direction which is oblique with respect to the direction of the conveyor path.
- 13. The apparatus of claim 12, wherein said first and second guns move along a direction which is approximately 45 degrees to the conveyor path.
- 14. An apparatus for dispensing adhesive to major and minor flaps of a container to form a siftproof seal, comprising:
a conveyor adapted to move a container along a conveying path; first, second, third, and fourth adhesive dispensing guns supported above said conveyor and movable to apply adhesive beads to respective major and minor flaps of the container along directions generally perpendicular to the conveying path; at least one motor associated with said guns and adapted to move said guns to thereby apply the adhesive along directions generally perpendicular to the conveying path; and a fifth adhesive dispensing gun supported above said conveyor and adapted to apply an adhesive bead to a major flap along a direction generally parallel to the conveying path.
- 15. The apparatus of claim 14, wherein said first, second, third, and fourth adhesive dispensing guns are linearly movable along a direction which is oblique to the direction of the conveyor path.
- 16. The apparatus of claim 14, wherein said first, second, third and fourth adhesive dispensing guns are movable in directions parallel and perpendicular to the conveying path.
- 17. A method of applying adhesive to respective first and second major flaps and first and second minor flaps of successive containers in a siftproof pattern, the method comprising:
moving successive containers along a conveying path, said major flaps being folded in an outwardly extending position and said minor flaps being folded in an inwardly extending position; moving first, second, third and fourth adhesive dispensing guns relative to the containers while dispensing first, second, third and fourth adhesive beads along first and second side edges of the first and second major flaps and along portions of the first and second minor flaps; stopping the dispensing of the first, second, third and fourth adhesive beads; dispensing a fifth bead of adhesive from a fifth dispensing gun along a free edge of the second major flap along a direction generally parallel to the conveying path; and stopping the dispensing of the fifth bead of adhesive.
- 18. The method of claim 17, wherein the step of moving and dispensing adhesive from the first, second, third and fourth guns includes:
dispensing third and fourth adhesive beads from the first and second guns to the first and second major flaps and portions of the second minor flap of a first one of the containers; and dispensing first and second adhesive beads from the third and fourth guns to the first and second major flaps and portions of the first minor flap of a second one of the containers.
