Packaging system having loading carousel
View Patent ↗A packaging system utilizes two sides of a loading carousel, which reduces both the height and footprint of the packaging system. Mass and inertia are also reduced, allowing higher operational speeds. The loading carousel receives opened cartons on a first side and lowers them over product groups on a second side.
1. A loading carousel for packaging articles in containers, the loading carousel having a first side and a second side, the loading carousel comprising:
a first rotatable support;
a second rotatable support;
a cam track comprising:
a pickup cam profile on the first side of the loading carousel; and
a loading cam profile on the second side of the loading carousel; and
a plurality of carriers for carrying containers to be loaded with articles, the plurality of carriers are mounted around the first and second rotatable supports, the carriers being mounted for moving about a periphery of the loading carousel and for vertical translation defined by the cam track, the carriers are configured to carry containers from a pickup position at a first side of the loading carousel where the containers are picked up, to a loading position at a second side of the loading carousel where the containers are lowered onto articles, wherein
the pickup cam profile defines a low pickup position of the carriers on the first side of the loading carousel wherein the carriers pickup a respective container to be loaded, and
the loading cam profile defines a low loading position of the carriers on the second side of the loading carousel wherein the carriers lower the container to be loaded onto the articles.
2. The loading carousel of claim 1 , wherein the cam track defines a first raised position for the carriers between the pickup position and the loading position and adjacent to the first rotatable support.
3. The loading carousel of claim 2 , wherein the cam track defines a second raised position for the carriers between the pickup position and the loading position and adjacent to the second rotatable support.
4. The loading carousel of claim 1 , wherein each carrier is mounted on at least one upright rod and is operatively connected to a cam follower engaged with the cam track.
5. The loading carousel of claim 1 , wherein the carriers comprise spaced arms sized to receive cartons.
6. The loading carousel of claim 1 , wherein the rotatable supports are rotated in unison by at least one chain, belt, or gear.
7. The loading carousel of claim 1 , in combination with containers and articles to be packaged, the loading carousel being configured to pickup containers in an opened configuration at the low pickup position at the first side of the loading carousel and to lower the containers in the opened configuration onto the articles at the low loading position at the second side of the loading carousel.
8. The loading carousel of claim 1 further comprising a plow positioned relative to the cam track to maintain the containers in an opened configuration between the low pickup position and the low loading position.
9. The loading carousel of claim 5 wherein the carriers comprise a laterally extending support plate, and the spaced arms of each carrier extend downwardly from the laterally extending support plate and are configured to grasp a respective container and carry the respective container form the low pickup position to the low loading position.
