Abstract

A system and method for activating a series of article protection features formed in product cartons in which a series of articles have been packaged includes an actuating assembly mounted along a path of travel for the cartons. The actuating assembly will include a series of actuating elements that are selectively moved into engagement with the article protection features of the cartons. The article protection features are urged into the cartons, between the articles therein and into positions engaging and supporting the articles.

First claim

What is claimed is:

1. In a method of packaging articles, wherein a loaded carton loaded with a plurality of articles is provided, the loaded carton being defined by a top, a bottom, a first side, a second side, a first end, and a second end; the top, the bottom, the first side, the second side, the first end, and the second end of the loaded carton being closed around the plurality of articles; the loaded carton including a first article protection feature; the plurality of articles including a first article and a second article; the improvement comprising:
moving the first article protection feature into the loaded carton;
wherein the first article protection feature engages at least the first article and moves the first article.

2. The method of claim 1 , the improvement further comprising:
stopping the moving of the first article protection feature into the loaded carton upon encountering a back pressure.

3. The method of claim 1 , wherein the plurality of articles further includes a third article and a fourth article, the improvement further comprising:
providing the carton with a second article protection feature;
moving the second article protection feature into the carton to engage the third article and the fourth article and to move the third article.

4. The method of claim 3 , wherein the second article protection feature is moved into the loaded carton after the first article protection feature is moved into the loaded carton.

5. The method of claim 3 , wherein the first article protection feature is farther from one of the first side or the first end than the second article protection feature, and wherein the first article protection feature and the second article protection feature are in a row.

6. The method of claim 3 , wherein the first article protection feature is moved into the carton in a first direction and the second article protection feature is moved into the carton in a second direction, and wherein the first direction is opposite the second direction.

7. The method of claim 6 , wherein the loaded carton is formed of paperboard, the improvement further comprising:
with the first article protection feature engaged with at least the first article in the loaded carton, the first article is separated from the second article by at least two layers of the paperboard.

8. The method of claim 6 , wherein the first article protection feature is moved into the loaded carton by an actuating member, wherein the plurality of articles are breakable, and wherein an overload protection mechanism disengages the actuating member from engagement with the first article protection feature upon encountering a back pressure from moving the first article protection feature into the loaded carton.

9. The method of claim 8 , wherein the overload protection mechanism comprises a cylinder biasing the actuating member toward a first operative position while enabling the actuating member to move to a second position with the actuating member out of engagement with the first article protection feature.

10. The method of claim 8 , wherein the actuating member is disposed on a wheel, and wherein the overload protection mechanism comprises a cylinder biasing the wheel toward a first operative position with the actuating member in engagement with the first article protection feature while enabling the wheel to move out of engagement with the first article protection feature to a first nonoperative position.

11. A method of packaging articles, comprising:
providing a loaded carton having an interior with a plurality of articles packed in the interior of the loaded carton; the interior being closed by a top, a bottom, a first side, a second side, a first end, and a second end; the plurality of articles including a first article and a second article;
tightening the packing of the plurality of articles by urging a first portion of the loaded carton into the interior of the loaded carton against at least the first article to move the first article.

12. The method of claim 11 , wherein the loaded carton is formed of paperboard and, with the first article moved by the urging of the first portion into the loaded carton against at least the first article, the first article is separated from the second article by at least two layers of the paperboard.

13. The method of claim 11 , further comprising:
stopping the urging of the first portion into the loaded carton upon encountering a back pressure.

14. The method of claim 11 , wherein the plurality of articles further including a third article and a fourth article, the method further comprising:
providing the carton with a second portion;
urging the second portion into the loaded carton against at least the third article to move the third article.

15. The method of claim 14 , wherein the second portion is moved into the loaded carton after the first portion is moved into the loaded carton.

16. The method of claim 15 , wherein the first portion is farther from the first end than the second portion, and wherein the first portion is closer to the first side than the second portion.

17. The method of claim 11 , wherein the first portion is moved into the loaded carton by an actuating member, wherein the plurality of articles are breakable, and wherein an overload protection mechanism disengages the actuating member from engagement with the first portion upon encountering a back pressure from moving the first portion into the loaded carton.

18. The method of claim 17 , wherein the overload protection mechanism comprises a cylinder biasing the actuating member toward a first operative position while enabling the actuating member to move to a second position with the actuating member out of engagement with the first portion.

19. The method of claim 17 , wherein the actuating member is disposed on a wheel, and wherein the overload protection mechanism comprises a cylinder biasing the wheel toward a first operative position with the actuating member in engagement with the first portion while enabling the wheel to move out of engagement with the first portion to a first nonoperative position.
