Abstract

A bale wrapping system that includes a belt that rotates to form and drive rotation of a bale of an agricultural product. The bale is configured to be wrapped with a wrapping layer of a bale wrap while rotating on the belt. A first portion of the wrapping layer overlaps a second portion of the wrapping layer while disposed on the belt. A glue system sprays a layer of glue onto the wrapping layer. The layer of glue enables the first portion of the wrapping layer to couple to the second portion of the wrapping layer.

First claim

The invention claimed is:

1. An agricultural implement, comprising:
a baler configured to bale an agricultural product, the baler comprising:
a belt configured to rotate to form a bale out of the agricultural product, and wherein the belt rotates the bale within the baler;

a bale wrapping system configured to wrap the bale with a wrapping layer of a bale wrap, the bale wrapping system comprising:
a glue system configured to spray a layer of glue onto the wrapping layer, wherein the layer of glue enables a first portion of the wrapping layer to couple to a second portion of the wrapping layer; and

a bale wrap treatment system configured to spray a fluid onto the wrapping layer to form a coating on the wrapping layer;
wherein the glue system comprises a wrap guide configured to spray the layer of glue onto the wrapping layer, and the wrap guide is configured to change position to drive the bale wrap into contact with the bale to enable the bale to grip the bale wrap, such that rotation of the bale draws the bale wrap around the bale.

2. The agricultural implement of claim 1 , wherein the bale wrap is cotton and is formed as a canvas, fabric, cloth, or a combination thereof.

3. The agricultural implement of claim 1 , wherein the wrap guide comprises one or more nozzles configured to spray the layer of glue onto the wrapping layer.

4. The agricultural implement of claim 1 , comprising a cutting system configured to cut the bale wrap to a length enabling the first portion of the wrapping layer to overlap with the second portion of the wrapping layer around the bale.

5. The agricultural implement of claim 1 , wherein the coating is a water repellent coating, an insect repellent coating, an anti-microbial coating, or a combination thereof.

6. The agricultural implement of claim 1 , wherein the bale wrap treatment system couples to a bale carrier.

7. The agricultural implement of claim 6 , comprising an actuator configured to move the bale carrier to release the bale.

8. The agricultural implement of claim 6 , wherein the bale carrier is configured to receive the bale wrapped with the bale wrap from the bale wrapping system.

9. The agricultural implement of claim 8 , wherein the bale wrap treatment system comprises a bale roller configured to rotate the bale on the bale carrier.

10. The agricultural implement of claim 9 , wherein the bale wrap treatment system comprises a sprayer configured to spray the fluid onto the bale wrap to form the coating on the bale wrap as the bale rotates on the bale carrier.

11. The agricultural implement of claim 1 , comprising a controller configured to control a sprayer of the bale wrap treatment system and to detect an amount of rotation of the bale.

12. The agricultural implement of claim 1 , wherein the wrap guide is configured to change position to drive the bale wrap over or below the wrap guide into contact with the bale.

13. The agricultural implement of claim 1 , wherein the bale wrap comprises one or more chemicals that react with the fluid to form the coating.

14. The agricultural implement of claim 1 , comprising a controller configured to detect a size of the bale, wherein in response to the size of the bale the controller is configured to release the bale wrap that surrounds the bale, and wherein the controller is further configured to detect an amount of bale wrap surrounding the bale and in response to the amount of the bale wrap surrounding the bale activate the glue system to spray the layer of glue onto the bale wrap to couple the bale wrap around the bale.

15. A bale wrapping system, comprising:
a belt configured to rotate to form and drive rotation of a bale of agricultural product, wherein the bale is configured to be wrapped with a wrapping layer of a bale wrap while rotating on the belt, such that a first portion of the wrapping layer overlaps a second portion of the wrapping layer while disposed on the belt; and
a glue system configured to spray a layer of glue onto the wrapping layer, wherein the layer of glue enables the first portion of the wrapping layer to couple to the second portion of the wrapping layer;
wherein the glue system comprises a wrap guide configured to spray the layer of glue onto the wrapping layer, and the wrap guide is configured to change position to drive the bale wrap into contact with the bale to enable the bale to grip the bale wrap, such that rotation of the bale draws the bale wrap around the bale.

16. The bale wrapping system of claim 15 , wherein the wrap guide comprises one or more nozzles configured to spray the layer of glue onto the wrapping layer.

17. The bale wrapping system of claim 15 , comprising a cutting system configured to cut the bale wrap to a length enabling the first portion of the wrapping layer to overlap with the second portion of the wrapping layer around the bale.

18. The bale wrapping system of claim 17 , wherein the cutting system is upstream from the glue system in a direction that the bale wrap unrolls.

19. The bale wrapping system of claim 15 , wherein the bale wrap is cotton and is formed as a canvas, fabric, cloth, or a combination thereof.

20. The bale wrapping system of claim 15 , wherein the wrap guide is configured to change position to drive the bale wrap over or below the wrap guide into contact with the bale.

21. A bale wrap treatment system, comprising:
a bale carrier configured to receive a bale wrapped with a bale wrap from a bale wrapping system;
a bale roller configured to rotate the bale on the bale carrier; and
a sprayer configured to spray a fluid onto the bale wrap to form a coating on the bale wrap as the bale rotates on the bale carrier;
wherein the bale wrap comprises one or more chemicals that react with the fluid to form the coating.

22. The bale wrap treatment system of claim 21 , wherein the coating is a water repellent coating, an insect repellent coating, an anti-microbial coating, or a combination thereof.

23. The bale wrap treatment system of claim 21 , comprising an actuator configured to move the bale carrier to release the bale.

24. The bale wrap treatment system of claim 21 , comprising a controller configured to control the sprayer and to detect an amount of rotation of the bale.
