Abstract

A baler includes a baling chamber for baling a crop to form a bale, a wrapping installation for wrapping the bale with a wrapping material during a wrapping operation, a sensor for detecting a noise signal, a control unit which is connected to the sensor. The control unit is configured to characterize the wrapping operation on the basis of a noise signal from the sensor.

First claim

What is claimed is:

1 . A baler implement comprising:
a baling chamber for baling a crop to form a bale; a wrapping installation for wrapping the bale with a wrapping material during a wrapping operation; a sensor for detecting a noise signal and generating a sensor signal indicative of the noise signal; and a controller which is connected to the sensor and configured for characterizing the wrapping operation on the basis of the sensor signal from the sensor.

2 . The baler implement set forth in claim 1 , wherein the controller is configured to establish an amplitude and a frequency of the sensor signal, and to characterize the wrapping operation based on the amplitude and the frequency of the sensor signal.

3 . The baler implement set forth in claim 2 , wherein the controller is configured to compare the amplitude and the frequency of the sensor signal with a threshold value.

4 . The baler implement set forth in claim 1 , wherein the noise signal is detected as a function of time, and wherein the controller is configured to characterize the wrapping operation on the basis of the sensor signal of the sensor as a function of time.

5 . The baler implement set forth in claim 4 , wherein the controller is configured to establish the amplitude of the sensor signal as a function of time and to compare the amplitude of the sensor signal as a function of time with a threshold value.

6 . The baler implement set forth in claim 1 , wherein the controller is configured to process the sensor signal with a Fourier transform.

7 . The baler implement set forth in claim 6 , wherein the controller is configured to filter the Fourier transform of the sensor signal using one of a high-pass filter or a low-pass filter.

8 . The baler implement set forth in claim 1 , wherein the controller is configured to generate one of an error signal or a completion signal as a function of an amplitude of the sensor signal above a threshold value.

9 . The baler implement set forth in claim 1 , wherein the sensor is arranged on one of the baling chamber, the wrapping installation or a frame of the baler implement.

10 . The baler implement set forth in claim 1 , wherein the sensor is one of a microphone or an ultrasonic sensor.

11 . The baler implement set forth in claim 1 , wherein the controller is configured to characterize the wrapping operation based on the sensor signal indicative of the noise signal using a model saved on the controller, wherein the model represents the wrapping operation, in accordance with the noise signal as a function of time during the wrapping operation.

12 . A method of operating a baler implement, the method comprising the steps of:
wrapping a bale with a wrapping material in a wrapping operation with a wrapping installation; detecting a noise signal with a sensor during the wrapping operation, whereby the sensor generates a sensor signal indicative of the noise signal; and characterizing the wrapping operation with a controller based on the sensor signal from the sensor.

13 . The method set forth in claim 12 , further comprising determining an amplitude of the sensor signal with respect to time with the controller.

14 . The method set forth in claim 13 , wherein characterizing the wrapping operation includes characterizing the wrapping operation based on the amplitude of the sensor signal with respect to time.

15 . The method set forth in claim 12 , wherein characterizing the wrapping operation includes comparing the amplitude of the sensor signal with respect to time to a threshold value.
