Abstract

A system, method and apparatus for applying container carriers to unitize a plurality of containers. A supply of container carriers are provided in connected sticks of two or more container carriers. An applicating drum is configured to accept a single container carrier stick from a queue and provide the container carrier stick to a supply of containers. A cutoff system is configured to cut the sticks of two or more container carriers into individual container carriers but not cut between adjacent unconnected sticks of container carriers.

First claim

The invention claimed is:

1 . A system for applying a container carrier to unitize a plurality of containers, the system comprising:
a supply of container carriers provided in connected sticks of two or more container carriers; an applicating drum configured to accept a single container carrier stick from a queue and provide to a supply of containers; and a cutoff system configured to selectively cut the connected sticks of two or more container carriers into individual container carriers but not intercede between adjacent unconnected sticks of container carriers, wherein the cutoff system includes an eccentric cam and a knife positioned along one edge of the eccentric cam.

2 . The system of claim 1 wherein the queue of container carrier sticks includes no gaps between adjacent connected sticks of two or more container carriers.

3 . The system of claim 1 wherein the cutoff system is configured to synchronize with a movement of the applicating drum.

4 . The system of claim 3 wherein the cutoff system is configured to pause between unconnected sticks of two or more container carriers.

5 . The system of claim 1 wherein the cutoff system is configured to cut the connected sticks of two or more container carriers while engaged with the applicating drum.

6 . The system of claim 1 further comprising
a push down wheel configured to move the container carrier from a first position in loose engagement with the plurality of containers into a second position in final engagement with the plurality of containers and thereby form a package of unitized containers.

7 . The system of claim 6 wherein the cut-off system is configured to cut container carriers following final engagement with the plurality of containers.

8 . A system for applying a container carrier to unitize a plurality of containers, the system comprising:
a supply of container carriers provided in connected sticks of two or more container carriers; an applicating drum configured to accept a single container carrier stick from a queue and provide to a supply of containers; and a cut-off system configured to selectively cut the connected sticks of two or more container carriers into individual container carriers but refrain from approach between adjacent unconnected sticks of two or more container carriers, wherein the cutoff system comprises:
an eccentric cam; and
a knife positioned along one edge of the eccentric cam, wherein the eccentric cam is configured to pause between unconnected sticks of container carriers.

9 . The system of claim 8 further comprising a push down wheel configured to move the container carrier from a first position in loose engagement with the plurality of containers into a second position in final engagement with the plurality of containers and thereby form a package of unitized containers.

10 . A system for applying a container carrier to unitize a plurality of containers, the system comprising:
a supply of container carriers provided in connected sticks of two or more container carriers; an applicating drum configured to accept a single container carrier stick from a queue and provide to a supply of containers; and a cutoff system configured to selectively cut the connected sticks of two or more container carriers into individual container carriers but not intercede between adjacent unconnected sticks of container carriers, wherein the cutoff system comprises a cutoff wheel having a plurality of knives spaced around a perimeter of the cutoff wheel, each knife for engaging a portion of the connected stick of two or more containers, wherein individual knives of the plurality of knives are omitted from the perimeter of the cutoff wheel where adjacent unconnected sticks of two or more container carriers are engaged.

11 . The system of claim 10 wherein the cutoff system is configured to cut the connected sticks of two or more container carriers while engaged with the applicating drum.

12 . The system of claim 10 further comprising a push down wheel configured to move the container carrier from a first position in loose engagement with the plurality of containers into a second position in final engagement with the plurality of containers and thereby form a package of unitized containers.

13 . The system of claim 12 wherein the cut-off system is configured to cut container carriers following final engagement with the plurality of containers.
