Abstract

A module wrapping assembly for a module builder having a first roller rotationally coupled to the module builder about a first axis, a bracket pivotally coupled to the module builder about a bracket axis, and a second roller rotationally coupled to the bracket about a second axis. Wherein, the second axis is offset from the bracket axis. Further wherein, the bracket is pivotable about the bracket axis to reposition the second axis relative to the first axis.

First claim

The invention claimed is:

1. A module wrapping assembly for a module builder, comprising:
a first roller rotationally coupled to the module builder about a first axis and configured to directly contact a wrap material;
a bracket pivotally coupled to the module builder about a bracket axis;
a second roller rotationally coupled to the bracket about a second axis and configured to directly contact the wrap material; and
a biasing member coupled to the bracket to bias the second roller towards the first roller;
wherein, the second axis is offset from the bracket axis;
further wherein, the bracket is pivotable about the bracket axis to reposition the second axis relative to the first axis and pinch the wrap material between the first roller and the second roller.

2. The module wrapping assembly of claim 1 , further wherein the first roller is rotationally driven by a drive system.

3. The module wrapping assembly of claim 2 , further wherein the second roller is rotationally driven by the drive system.

4. The module wrapping assembly of claim 1 , further comprising a carry roller rotationally coupled to the module builder about a carry axis, wherein the carry axis is offset from the first axis to carry a wrap roll there between.

5. The module wrapping assembly of claim 1 , further wherein the second roller pivots about the bracket axis between a first position and a second position.

6. The module wrapping assembly of claim 5 , wherein in the first position the second roller is positioned substantially adjacent to the first roller to position the wrap material there between and in the second position the second roller is spaced from the first roller to provide a gap there between.

7. The wrapping assembly of claim 1 , further comprising a wrap path defined by the first and second rollers and extending to a module forming chamber, wherein the wrap path is configured to direct the wrap material from a wrap roll positioned partially on the first roller to the module forming chamber, wherein the wrap path is defined at least partially between the first and second roller.

8. The wrapping assembly of claim 7 , further wherein the bracket axis is positioned relative to the second axis to bias the second roller towards the first roller when a stretch force is applied to the wrap material between the second roller and the module forming chamber.

9. A module wrapping assembly, comprising:
a housing having a first wall and a second wall and partially defining a module forming chamber;
a first roller rotationally coupled to the first wall and the second wall about a first roller axis;
a first bracket pivotally coupled to the first wall about a bracket axis;
a second bracket pivotally coupled to the second wall about the bracket axis; and
a second roller rotationally coupled between the first and second bracket about a second roller axis;
wherein, the second roller is pivotable about the bracket axis between a first position and a second position;
wherein, a wrap path for a wrap material is defined partially around the second roller extending towards the module forming chamber at a wrap path direction;
wherein, a force applied in the wrap path direction by the wrap material biases the second roller about the bracket axis towards the first roller;
wherein, in the first position the second roller is positioned substantially adjacent to the first roller and in the second position the second roller is spaced from the first roller to provide a gap there between;
wherein in the first position a surface of the first roller and a surface of the second roller contact wrap material positioned therebetween.

10. The module wrapping assembly of claim 9 , further comprising a carry roller rotationally coupled between the first wall and the second wall about a carry axis, wherein the carry axis is offset from the first roller axis and the first roller and carry roller are spaced to carry a wrap roll at least partially thereon.

11. The module wrapping assembly of claim 10 , further wherein the first roller has a first diameter and the carry roller has a carry diameter, the carry diameter being less than the first diameter.

12. The module wrapping assembly of claim 9 , further wherein the second roller is rotationally driven by a drive system having a sprocket or geared engagement.

13. The module wrapping assembly of claim 9 , further comprising a biasing member positioned between at least one of the first or second bracket and the corresponding first or second wall, the biasing member providing a biasing force on the second roller towards the first position.

14. The wrapping assembly of claim 13 , further comprising a lock assembly coupled to at least one of the first bracket or the second bracket, wherein the lock assembly selectively locks the second roller in the first position.

15. A module building system, comprising:
a module chamber having a plurality of belts positioned there around and configured to form a round module; and
a module wrapping assembly coupled to the module chamber, the module wrapping assembly comprising:
a first roller rotationally coupled between a first wall and a second wall and configured to directly contact a wrap material and configured to at least partially support a wrap roll thereon;
a bracket pivotally coupled to the module wrapping assembly about a bracket axis;
a second roller rotationally coupled to the bracket along a second axis, the second axis being offset from the bracket axis, the second roller configured to directly contact the wrap material and configured to be spaced from the wrap roll; and
a biasing member coupled to the bracket to bias the second roller towards the first roller;
wherein, the bracket pivots about the bracket axis together with the second axis, moving the second roller relative to the first roller to selectively pinch the wrap material between the first roller and the second roller.

16. The module building system of claim 15 , further wherein the first and second roller define a wrap path from the wrap roll to the module chamber, wherein the wrap material is pinched between the first and second roller prior to entering the module chamber.

17. The module building system of claim 16 , further wherein the wrap material is stretched between the second roller and the module chamber by a stretch force, wherein the stretch force biases the second roller towards the first roller.
