Abstract

A method and a bale wrapping device for wrapping a bale. The method includes receiving a bale at a bale moving ramp device of the bale wrapping device. The bale on the bale moving ramp device is moved through a bale wrapping frame. The sheet of wrapping material is applied on the bale to wrap the bale as the bale passes through the bale wrapping frame, and a roller on the bale wrapping frame holds a roll of the sheet of wrapping material.

Claims (23)

1 . A method for wrapping a bale by a bale wrapping device, the method comprising:

receiving a bale at a bale moving ramp device of the bale wrapping device;

moving the bale on the bale moving ramp device through a bale wrapping frame;

applying a sheet of wrapping material on the bale to wrap the bale as the bale passes through the bale wrapping frame, wherein a roller on the bale wrapping frame holds a roll of the sheet of wrapping material;

receiving a bale at the bale moving ramp device, wherein the received bale is part of a row of bales;

applying the sheet of wrapping material on the row of bales continuously in a first orientation when the row of bales passes through the bale wrapping frame, wherein the first orientation is along a length of the row of bales; and

applying a wrapping element on the row of bales continuously in a second orientation when the row of bales passes through the bale wrapping frame, wherein the second orientation is different from the first orientation, and the second orientation is along a perimeter of the row of bales.

2 . The method of claim 1 , wherein the sheet of wrapping material is a material that repels liquid water.

3 . The method of claim 1 , wherein the sheet of wrapping material is a plastic material.

4 . The method of claim 1 , further comprising:

attaching one or more sensors to the row of bales, wherein the one or more sensors are configured to measure at least a first parameter within the row of bales at a position where the one or more sensors are attached to the row of bales, and the first parameter is indicative of bale quality.

5 . The method of claim 4 , wherein the first parameter is one of moisture, temperature, and humidity.

6 . The method of claim 1 , wherein the roller on the bale wrapping frame that holds the roll of the sheet of wrapping material is positioned at a top position of the bale wrapping frame.

7 . The method of claim 6 , wherein a pair of side rollers on the bale wrapping frame hold a roll of the film layer at a right side and a left side of the bale wrapping frame.

8 . The method of claim 1 , wherein a wrapping mechanism on the bale wrapping frame holds a roll of the wrapping element.

9 . The method of claim 1 , wherein the wrapping element applied on the row of bales continuously in the second orientation is a twine or mesh type wrapping material.

10 . A bale wrapping device for wrapping a bale, the bale wrapping device configured to:

receive a bale at a bale moving ramp device of the bale wrapping device;

move the bale on the bale moving ramp device through a bale wrapping frame;

apply a sheet of wrapping material on the bale to wrap the bale as the bale passes through the bale wrapping frame, wherein a roller on the bale wrapping frame holds a roll of the sheet of wrapping material;

receive a bale at the bale moving ramp device, wherein the received bale is part of a row of bales;

apply the sheet of wrapping material on the row of bales continuously in a first orientation when the row of bales passes through the bale wrapping frame, wherein the first orientation is along a length of the row of bales; and

apply a wrapping element on the row of bales continuously in a second orientation when the row of bales passes through the bale wrapping frame, wherein the second orientation is different from the first orientation, and the second orientation is along a perimeter of the row of bales.
