Apparatus and method for a carton carrier
This invention relates to a product cartoning system having dynamic carton carriers that may restrain or not restrain the package during different steps of the cartoning process. Certain steps such as vibrating may benefit from open carton carriers while other steps such as closing a side of the carton may benefit from closed carton carriers. This invention also relates to a product cartoning system having adjustable carton carriers driven by more than one carton chain to allow varying a width between two of the carton carrier sidewalls to accommodate different size or shape cartons. This invention also relates to methods of use for the product cartoning systems of this invention.
1. A product cartoning system comprising:
a first continuous carton chain movable on a frame;
a second continuous carton chain movable on the frame and movable relative to the first carton chain;
a sidewall cam positioned along the frame; and
a plurality of carton carriers, each carton carrier of the carton carriers including a cam follower, a first sidewall disposed on the first carton chain and a second sidewall disposed on the second carton chain, wherein a width between the first sidewall and the second sidewall is variable as the plurality of carton carriers move along the frame by altering a relative position of the first carton chain to the second carton chain, wherein the width between the first sidewall and the second sidewall changes following engagement of the cam follower with the sidewall cam at a position along the frame.
2. The product cartoning system of claim 1 , wherein an adjustment of the relative position of the first carton chain to the second carton chain is made by a servo interconnect.
3. The product cartoning system of claim 1 , wherein the carton carriers are disposed in a position selected from the group consisting of substantially vertical and substantially horizontal.
4. The product cartoning system of claim 1 , wherein the first sidewall is leading relative to the second sidewall which follows.
5. The product cartoning system of claim 1 , further comprising at least a third sidewall positioned on a third continuous carton chain on at least a portion of the frame.
6. The product cartoning system of claim 1 , further comprising a carton placement and erection device.
7. A product cartoning system comprising:
a first continuous carton chain movable on a frame;
a second continuous carton chain movable on the frame and movable relative to the first carton chain during engagement with a carton;
a sidewall cam positioned along the frame; and
a plurality of carton carriers, each carton carrier of the carton carriers including a cam follower, a first sidewall disposed on the first carton chain and a second sidewall disposed on the second carton chain, wherein a width between the first sidewall and the second sidewall is variable as the plurality of carton carriers move along the frame by altering a relative position of the first carton chain to the second carton chain, wherein the width between the first sidewall and the second sidewall adjusts several times following engagement of the cam follower with the sidewall cam at a position along the frame.
8. The product cartoning system of claim 7 , wherein the first sidewall is leading relative to the second sidewall which follows.
9. The product cartoning system of claim 7 , further comprising at least a third sidewall positioned on a third continuous carton chain along at least a portion of the frame.
10. The product cartoning system of claim 7 , further comprising a carton placement and erection device.
