Abstract

In a method for operating a system, a first vibration is imparted to a component of the system and the first vibration of the component is detected by a sensor. The sensor generates a sensor signal for transmission to a control device, which analyzes the sensor signal and determines whether a buildup is present on the component based upon the analysis of the sensor signal. A second vibration is imparted to the component to remove the buildup when the buildup has been detected.

First claim

What is claimed:

1 .- 12 . (canceled)

13 . A method for operating a system, said method comprising:
imparting a first vibration to a component of the system; detecting the first vibration of the component by a sensor operably connected to the component; providing a sensor signal from the sensor to a control device; analyzing the sensor signal by the control device; determining whether a buildup is present on the component based upon the analysis of the sensor signal; and imparting a second vibration to the component to remove the buildup when the buildup has been detected.

14 . The method of claim 13 , wherein the sensor determines a frequency, an amplitude and/or a phase of the first vibration and provides the sensor signal based on the frequency, amplitude and/or phase.

15 . The method of claim 13 , wherein the first and second vibrations are imparted by an excitation unit.

16 . The method of claim 13 , wherein the first vibration is excited by a first excitation unit and the second vibration is excited by a second excitation unit.

17 . The method of claim 13 , wherein a presence of the buildup is determined on the basis of a variance in a Fourier spectrum of the sensor signal.

18 . The method of claim 13 , wherein at least one of the first vibration and the second vibration is imparted at a frequency which increases from 0.1 Hz to 1 kHz.

19 . The method of claim 13 , wherein at least one of the first vibration and the second vibration is imparted at a frequency which increases from 1 to 50 Hz.

20 . The method of claim 16 , wherein the first excitation unit and/or the second excitation unit impart the first and second vibrations, respectively, to the component at a resonance frequency of the component.

21 . The method of claim 13 , wherein at least one of the first vibration and/or the second vibration is imparted by impulses.

22 . A system, comprising:
a component, a first excitation unit capable of imparting a first vibration to the component; a sensor operably connected to the component to determine a frequency, amplitude and/or phase of the first vibration and to provide a sensor signal; and a control device operably connected to the first excitation unit and the sensor, said control device configured to analyze the sensor signal, to determine whether a buildup is present on the component based upon the analysis of the sensor signal, and to cause a second vibration to be imparted upon the component to remove the buildup when the buildup has been detected.

23 . The system of claim 22 , further comprising a second excitation unit to impart the second vibration to the component.

24 . The system of claim 22 , wherein the first excitation unit is configured to impart the first and second vibrations to the component.

25 . The system of claim 22 , constructed in the form of a tube mill, a filling device, a hopper or a storage vessel.

26 . A computer program product for operating a system, comprising a computer program embodied in a non-transitory computer readable medium, wherein the computer program, when loaded into a processor unit and executed by the processor unit, causes the processor unit to perform the steps of:
imparting a first vibration to a component of the system, detecting the first vibration of the component by a sensor operably connected to the component, providing a sensor signal from the sensor to a control device, analyzing the sensor signal by the control device, determining whether a buildup is present on the component based upon the analysis of the sensor signal, and imparting a second vibration to the component to remove the buildup when the buildup has been detected.
