Abstract

A combination of a towing vehicle and a baler includes a control unit which is connected to an actuator. The actuator is specified to adjust and/or set an angle between a drawbar and the baler. The control unit, as a function of an unloading signal, is able to be operated so as to actuate the actuator in such a manner that, for unloading a fully formed or fully wrapped bale from the baler in a specified direction, an unloading angle between the drawbar and the baler is able to be set in such a way that the bale is able to be ejected from the baler in the specified direction.

First claim

What is claimed is:

1 . A baling combination comprising:
a towing vehicle; a baler drawn by the towing vehicle via a drawbar connecting the towing vehicle and the baler; an actuator coupled to the drawbar and one of the towing vehicle and the baler, wherein the actuator is operable to adjust and angle between the drawbar and the baler; a controller including a processor and a memory having an algorithm stored thereon, wherein the processor is operable to execute the algorithm to control the actuator as a function of an unloading signal to achieve a desired unloading angle between the drawbar and the baler, whereby a bale may be unloaded from the baler in a specified direction.

2 . The baling combination set forth in claim 1 , further comprising an inclination sensor for detecting an inclination of the baler in the form of an inclination signal, wherein the controller is connected to the inclination sensor for receiving the inclination signal from the inclination sensor, and wherein the controller is operable to define the unloading angle based on the inclination signal.

3 . The baling combination set forth in claim 1 , further comprising a Global Positioning Satellite (GPS) system for determining a position of one of the towing vehicle and the baler in the form of a position signal, wherein the controller is connected to the GPS system for receiving the position signal from the GPS installation, and wherein the controller is configured to define the unloading angle based on the position signal.

4 . The baling combination set forth in claim 1 , further comprising a steering installation, wherein the controller is connected to the steering installation for controlling the steering installation as a function of the unloading signal so as to control the steering installation in such a manner that the towing vehicle is moved to an unloading position by the steering installation.

5 . The baling combination set forth in claim 1 , further comprising an input and output unit, wherein the controller is connected to the input and output unit, and wherein the unloading signal is able to be generated by the input and output unit and transmitted to the controller.

6 . The baling combination set forth in claim 1 , wherein the unloading signal is generated by the controller at one of: before a pressing phase of the baler is completed, when the pressing phase of the baler is completed, before a wrapping phase of the baler is completed, or when the wrapping phase of the baler is completed.

7 . The baling combination set forth in claim 1 , wherein the controller is operable to actuate an ejection unit to eject the bale when the unloading angle and an unloading position are set.

8 . The baling combination set forth in claim 1 , wherein the towing vehicle includes an input and output unit connected to controller, wherein the input and output unit is operable to communicate a confirmation signal to the controller when the unloading angle or an unloading position are set.

9 . The baling combination set forth in claim 1 , wherein the towing vehicle includes an input and output unit connected to the controller, wherein the input and output unit is operable to generate an ejection signal to control an ejection unit to eject the bale.

10 . A method of operating a baling combination including a towing vehicle and a baler pulled by the towing vehicle via a drawbar, wherein an angle between the drawbar and the baler is set by an actuator, wherein, for unloading a fully formed bale from the bale in a specified direction, an unloading angle between the drawbar and the baler is defined by a controller which controls the actuator as a function of an unloading signal in such a way that the bale is ejected from the baler at the unloading angle.

11 . The method set forth in claim 10 , wherein an inclination of the baling combination is detected in the form of an inclination signal, and the unloading angle (EW) and/or an unloading position are/is determined and/or evaluated by the controller as a function of the inclination signal.

12 . The method set forth in claim 10 , wherein the position of the baling combination is detected in the form of a position signal from a GPS sensor, and the unloading angle and/or an unloading position are/is determined by the controller as a function of the position signal.

13 . The method set forth in claim 11 , wherein the baling combination includes a steering installation, and wherein the method includes the controller operating the steering installation to move the baling combination to the unloading position as a function of the unloading signal.

14 . The method set forth in claim 10 , wherein the unloading signal is generated before one of a pressing phase has been completed, when the pressing phase is completed, before a wrapping phase is completed, or when the wrapping phase is completed.

15 . A baler comprising:
a frame a drawbar connected to the frame and configured for attachment to a towing vehicle whereby the towing vehicle may pull the frame; an actuator interconnecting the frame and the drawbar and configured for adjusting an angle between the frame and the drawbar; a controller connected to the actuator, and configured to control the actuator as a function of an unloading signal so as to actuate the actuator in such a manner that, for unloading the fully pressed bale from the baler in a specified direction, an unloading angle (EW) between the drawbar and the baler is defined by the controller in such a way that the bale is able to be ejected from the baler in the specified direction.
