Abstract

A baler implement includes a bale formation system operable to form crop material into a bale and eject the bale into an unloading zone. An object detection sensor is positioned to detect data related to the unloading zone. A baler controller is operable to determine if an object is present in the unloading zone or if an object is not present in the unloading zone based on a data signal from the object detection sensor. When an object is not present in the unloading zone, the controller may initiate the bale ejection sequence to eject the bale. When an object is present in the unloading zone, the controller may prevent initiation of the bale ejection sequence to prevent ejection of the bale onto the object.

First claim

What is claimed is:

1. A round baler implement comprising:
a frame;
at least one ground engaging element supporting the frame relative to a ground surface;
a tongue attached to the frame and configured for attachment to a tow vehicle for moving the frame across the ground surface;
a housing supported by the frame and defining an interior region, wherein the housing includes a forward portion and a rear gate rotatable relative to the forward portion about a gate rotation axis between a closed position and an open position;
a bale formation system disposed within the interior of the housing and operable to form crop material into a bale having a cylindrical shape;
wherein the rear gate is disposed in the closed position during formation of the bale, and wherein the rear gate is moved into the open position to eject the bale from the bale formation system;
an object detection sensor positioned and operable to detect data related to an unloading zone disposed immediately rearward of the rear gate;
a baler controller in communication with the object detection sensor, the baler controller including a processor and a memory having unloading algorithm stored thereon, wherein the processor is operable to execute the unloading algorithm to:
receive a bale ejection command to initiate a bale ejection sequence to eject the bale from the bale formation system;
receive a data signal from the object detection sensor related to the unloading zone;
determine if an object is present in the unloading zone or if an object is not present in the unloading zone based on the data signal from the object detection sensor;
initiate the bale ejection sequence to eject the bale from the bale formation system when an object is not present in the unloading zone; and
prevent initiation of the bale ejection sequence to prevent ejection of the bale from the bale formation system when an object is present in the unloading zone.

2. The round baler implement set forth in claim 1 , wherein the object detection sensor is one of a camera, a radar sensor, a lidar sensor, a thermal sensor, an infrared sensor, a Terahertz sensor, or a proximity sensor.

3. The round baler implement set forth in claim 1 , wherein the processor is operable to execute the unloading algorithm to identify the object detected in the unloading zone.

4. The round baler implement set forth in claim 3 , wherein the processor is operable to execute the unloading algorithm to communicate a signal to a communicator, wherein the signal includes the identified object detected in the unloading zone.

5. The round baler implement set forth in claim 3 , wherein the processor is operable to execute the unloading algorithm to classify the identified object detected in the unloading zone as an animal object or as a non-animal object.

6. The round baler implement set forth in claim 5 , wherein the processor is operable to execute the unloading algorithm to communicate a signal to an alert device when the identified object is classified as an animal object.

7. The round baler implement set forth in claim 1 , wherein the processor is operable to execute the unloading algorithm to initiate the bale detection sequence upon the object exiting the unloading zone.

8. The round baler implement set forth in claim 1 , wherein the processor is operable to execute the unloading algorithm to determine if a bale is currently present in the bale formation system or if no bale is currently present in the bale formation system.

9. The round baler implement set forth in claim 8 , wherein the processor is operable to execute the unloading algorithm to initiate the bale ejection sequence when no bale is currently present in the bale formation system and an object is present in the unloading zone.

10. The round baler implement set forth in claim 1 , wherein the processor is operable to execute the unloading algorithm to determine a profile of the ground surface.

11. The round baler implement set forth in claim 10 , wherein the processor is operable to execute the unloading algorithm to define a boundary of the unloading zone based on the profile of the ground surface.

12. A baler implement comprising:
a frame;
at least one ground engaging element supporting the frame relative to a ground surface;
a tongue attached to the frame and configured for attachment to a tow vehicle for moving the frame across the ground surface;
a bale formation system operable to form crop material into a bale and eject the bale therefrom rearward into an unloading zone;
an object detection sensor positioned and operable to detect data related to the unloading zone;
a baler controller in communication with the object detection sensor, the baler controller including a processor and a memory having unloading algorithm stored thereon, wherein the processor is operable to execute the unloading algorithm to:
receive a bale ejection command to initiate a bale ejection sequence to eject the bale from the bale formation system;
receive a data signal from the object detection sensor related to the unloading zone;
determine if an object is present in the unloading zone or if an object is not present in the unloading zone based on the data signal from the object detection sensor;
initiate the bale ejection sequence to eject the bale from the bale formation system when an object is not present in the unloading zone; and
prevent initiation of the bale ejection sequence to prevent ejection of the bale from the bale formation system when an object is present in the unloading zone.

13. The baler implement set forth in claim 12 , wherein the object detection sensor is one of a camera, a radar sensor, a lidar sensor, a thermal sensor, an infrared sensor, a Terahertz sensor, or a proximity sensor.

14. The baler implement set forth in claim 12 , wherein the processor is operable to execute the unloading algorithm to identify the object detected in the unloading zone and communicate a signal to a communicator, wherein the signal includes the identified object detected in the unloading zone.

15. The baler implement set forth in claim 12 , wherein the processor is operable to execute the unloading algorithm to classify the object detected in the unloading zone as an animal object or as a non-animal object.

16. The baler implement set forth in claim 15 , wherein the processor is operable to execute the unloading algorithm to communicate a signal to an alert device when the object is classified as an animal object.

17. The baler implement set forth in claim 12 , wherein the processor is operable to execute the unloading algorithm to determine if a bale is currently present in the bale formation system or if no bale is currently present in the bale formation system.

18. The baler implement set forth in claim 17 , wherein the processor is operable to execute the unloading algorithm to initiate the bale ejection sequence when no bale is currently present in the bale formation system and an object is present in the unloading zone.
