Abstract

A method and apparatus for settling a product in a partially formed package. In one aspect, the invention comprises the steps: providing a partially formed package; filling the partially formed package with a product; and settling the product in the partially formed package. The settling step comprises rotating a paddle wheel comprising at least one paddle against the partially formed package. In a second aspect, the invention comprises an improved product settler for settling product in a partially formed package. The improved product settler comprises a paddle wheel. The paddle wheel comprises at least one paddle that is positioned to cause an impact against the partially formed package. The impact agitates the partially formed package and thereby settles the product.

First claim

What is claimed:

1. An apparatus comprising an improved product settler for settling product in a partially formed package; wherein the product settler comprises:
a paddle wheel;
wherein the paddle wheel comprises at least one paddle that is positioned and configured to cause an impact against the partially formed package above an unsettled height of the product in the partially formed package; and
wherein the impact agitates the partially formed package and thereby settles the product;
wherein the product settler is configured so that the impact against the partially formed package settles the product from the unsettled height to a settled height of the product in the partially formed package, wherein the settled height is lower than the unsettled height.

2. The apparatus of claim 1 , wherein the apparatus comprises a source of pressurized gas.

3. The apparatus of claim 2 , wherein the apparatus comprises a nozzle configured to direct the pressurized gas into the partially formed package.

4. The apparatus of claim 1 , wherein the product settler comprises a controller configured to set a number of impacts per minute that the paddle wheel causes on the partially formed package.

5. The apparatus of claim 1 , wherein the product settler comprises a positional sensor configured to determine a position of the paddle wheel.

6. The apparatus of claim 1 , wherein the apparatus comprises a positional sensor configured to determine a position of the paddle wheel.

7. The apparatus of claim 1 , wherein the impact occurs on one and only one face of the partially formed package.

8. The apparatus of claim 1 , wherein the paddle wheel is configured to directly contact the partially formed package to cause the impact.

9. The apparatus of claim 1 , wherein the product settler comprises a motor, and wherein the product settler and the motor are configured and wherein the motor has sufficiently low torque so that if the motor turns off while the paddle wheel is in contact with the partially formed package, as the partially formed package is conveyed, the partially formed package will push the paddle wheel out of a path of the partially formed package.

10. The apparatus of claim 1 , wherein the product settler is modular.

11. The apparatus of claim 1 , wherein the product settler comprises a frame configured to spatially fix the product settler in relation to a path of the partially formed package.

12. The apparatus of claim 1 , wherein the product settler comprises a first adjustable mount configured to move the product settler in a first direction.

13. The apparatus of claim 1 , wherein the paddle wheel comprises a plurality of paddles.

14. The apparatus of claim 1 , wherein the apparatus comprises a form, fill and seal machine.

15. The apparatus of claim 14 , wherein the form, fill and seal machine comprises two seal jaw carriages; wherein a plurality of seal jaws are fixed to the seal jaw carriages; wherein the plurality of seal jaws are configured to form a first end seal to provide the partially formed package; wherein the plurality of seal jaws are configured to form a second end seal, thereby forming a package from the partially formed package; and wherein the product settler is located adjacent to one and only one side of the seal jaw carriages.

16. The apparatus of claim 1 , wherein the apparatus comprises a form, fill and seal machine configured to advance film continuously along a product conduit configured to conduct the product into the partially formed package.

17. The apparatus of claim 16 , wherein the apparatus is configured so that the paddle wheel rotates intermittently by rotating, stopping rotation, and then rotating again; and
wherein the apparatus is configured so that the paddle wheel rotates intermittently while the form, fill and seal machine advances film continuously along the product conduit.

18. The apparatus of claim 16 , wherein the apparatus is configured so that the paddle wheel rotates continuously while the form, fill and seal machine advances film continuously along the product conduit.

19. The apparatus of claim 1 , wherein the product settler is configured to be located adjacent to one and only one face of the partially formed package.

20. The apparatus of claim 1 , wherein the product settler is configured so that the impact against the partially formed package occurs above the unsettled height of the product in the partially formed package and below a product conduit through which the product is introduced into the partially formed package.

21. The apparatus of claim 1 , wherein the product settler is configured to agitate the partially formed package in a cycle that comprises: (i) impacting the partially formed package to move the partially formed package into a deformed position, and (ii) subsequently allowing the partially formed package to move out of the deformed position; and
wherein the product settler is configured to repeatedly perform the cycle to cause a plurality of impacts against the partially formed package.

22. The apparatus of claim 1 , wherein the product settler is configured to cause vibration of the partially formed package as a result of repeating a cycle involving the partially formed package, wherein the cycle comprises the partially formed package being pushed by the impact with the at least one paddle and then the partially formed package being allowed to return to a position of the partially formed package before the impact.

23. The apparatus of claim 1 , wherein the product settler is configured to contact one and only one face of the partially formed package.

24. The apparatus of claim 1 , wherein the product settler is configured to cause the impact repeatedly against the partially formed package, thereby providing impacts against the partially formed package at a rate of more than 180 impacts per minute.

25. The apparatus of claim 24 , wherein the product settler is configured to cause the impact repeatedly against the partially formed package, thereby providing impacts against the partially formed package at a rate of up to 900 impacts per minute.

26. The apparatus of claim 1 , wherein the product settler is configured to cause the impact repeatedly against the partially formed package, thereby providing impacts against the partially formed package at a rate of at least 300 and up to 900 impacts per minute.

27. The apparatus of claim 1 , wherein the product settler is configured to operate intermittently.

28. The apparatus of claim 1 , wherein the product settler is configured to operate continuously.

29. The apparatus of claim 1 , wherein the apparatus comprises one and only one product settler and wherein the one and only one product settler is configured to cause impacts against one and only one face of the partially formed package.

30. The apparatus of claim 29 , wherein the product settler comprises one and only one paddle wheel and wherein the one and only one paddle wheel is configured to cause impacts against the one and only one face of the partially formed package.
