Abstract

A baler implement includes a wrap system having a first spool roller and a second spool roller arranged in parallel and positioned to form a nip therebetween. The first and second spool rollers are configured to receive a wrap material through the nip and discharge the wrap material from the nip toward an inlet of a baling chamber. A scraper is positioned on the outlet side of the nip adjacent to the first spool roller for guiding the wrap material away from a circumferential exterior surface of the first spool roller to prevent the wrap material from wrapping around the first spool roller. The scraper includes an undulating edge defining a plurality of peaks and a plurality of valleys with the plurality of peaks positioned proximate to the circumferential exterior surface of the first spool roller.

First claim

What is claimed is:

1. A baler implement comprising:
a baling system defining a baling chamber having an inlet into the baling chamber, wherein the baling system is operable to receive crop material into the baling chamber through the inlet and form the crop material into a bale within the baling chamber;
a wrap system operable to insert a wrap material through the inlet and into the baling chamber to wrap the bale, the wrap system including:
a first spool roller and a second spool roller arranged in parallel and positioned to form a nip therebetween, wherein the first spool roller and the second spool roller are configured to receive the wrap material from a supply roll through an entrance side of the nip and discharge the wrap material toward the inlet of the baling chamber through an outlet side of the nip;
a scraper positioned on the outlet side of the nip adjacent to the first spool roller for guiding the wrap material away from a circumferential exterior surface of the first spool roller; and
wherein the scraper includes an undulating edge defining a plurality of peaks and a plurality of valleys with the plurality of peaks positioned proximate to the circumferential exterior surface of the first spool roller.

2. The baler implement set forth in claim 1 , wherein the scraper includes a panel extending parallel with the first spool roller and defining the undulating edge of the scraper.

3. The baler implement set forth in claim 2 , wherein the panel is arranged to position the plurality of peaks of the undulating edge a separation distance measured from a tangent line passing through the nip between the first spool roller and the second spool roller.

4. The baler implement set forth in claim 3 , wherein the separation distance is equal to or greater than ten millimeters.

5. The baler implement set forth in claim 2 , wherein the panel is arranged to position the plurality of peaks of the undulating edge a first orthogonal distance from the circumferential exterior surface of the first spool roller.

6. The baler implement set forth in claim 5 , wherein the panel is arranged to position the plurality of valleys of the undulating edge a second orthogonal distance from the circumferential exterior surface of the first spool roller, wherein the first orthogonal distance is less than the second orthogonal distance.

7. The baler implement set forth in claim 2 , wherein the panel includes a resilient material.

8. The baler implement set forth in claim 7 , wherein the resilient material is one of a steel or a plastic.

9. The baler implement set forth in claim 1 , wherein the plurality of peaks and the plurality of valleys are arranged in an alternating sequence in which each one of the plurality of valleys is disposed between a respective pair of adjacent peaks of the plurality of peaks.

10. The baler implement set forth in claim 9 , wherein each respective pair of the adjacent peaks define a peak-to-peak distance therebetween that is between the range of ten millimeters and one hundred millimeters.

11. The baler implement set forth in claim 1 , wherein the undulating edge includes an edge length that is equal to or greater than one half a roller length of the first spool roller along a respective axis of rotation of the first spool roller.

12. The baler implement set forth in claim 11 , wherein the edge length of the undulating edge is substantially equal to the roller length of the first spool roller.

13. The baler implement set forth in claim 1 , wherein the first spool roller includes an elastic material forming the exterior circumferential surface thereof.

14. The baler implement set forth in claim 13 , wherein the elastic material includes a rubber material.

15. The baler implement set forth in claim 1 , wherein the first spool roller and the second spool roller are configured to rotate about respective axes of rotation in opposite rotational directions relative to each other.

16. The baler implement set forth in claim 1 , wherein the undulating edge defines a finger depth measured perpendicularly relative to and between an apex of a respective one of the plurality of peaks and a root of a respective adjacent one of the plurality of valleys, wherein the finger depth is equal to or greater than three millimeters.

17. A wrap system for a baler implement, the wrap system comprising:
a first spool roller and a second spool roller arranged in parallel and positioned to form a nip therebetween, wherein the first spool roller and the second spool roller are configured to receive a wrap material from a supply roll through an entrance side of the nip and discharge the wrap material through an outlet side of the nip;
wherein the first spool roller includes an elastic material forming an exterior circumferential surface thereof;
a scraper positioned on the outlet side of the nip adjacent to the first spool roller for guiding the wrap material away from the circumferential exterior surface of the first spool roller; and
wherein the scraper includes an undulating edge defining a plurality of peaks and a plurality of valleys with the plurality of peaks positioned proximate to the circumferential exterior surface of the first spool roller.

18. The wrap system set forth in claim 17 , wherein the undulating edge includes an edge length that is equal to or greater than one half a roller length of the first spool roller along a respective axis of rotation of the first spool roller.

19. The wrap system set forth in claim 17 , wherein the panel is arranged to position the plurality of peaks of the undulating edge a separation distance measured from a tangent line passing through the nip between the first spool roller and the second spool roller.

20. The baler implement set forth in claim 17 , wherein the undulating edge defines a finger depth measured perpendicularly relative to and between an apex of a respective one of the plurality of peaks and a root of a respective adjacent one of the plurality of valleys, wherein the finger depth is equal to or greater than three millimeters.
