Definitions

• the invention relates to a method for monitoring industrial systems, in particular machine tools, robots or the like, by means of sensors, which determine at least one state of the industrial system, convert into signals and pass corresponding signals to an evaluation.
• Machine components that are to be monitored in any case are those that perform movements. These include mainly aggregates that operate on the appropriate processing axes, such as slides, spindles, but also their drive shafts, bearings, etc.
• Object of the present invention is to improve the monitoring of industrial systems mentioned above and in particular to accelerate error detection.
• an analysis program is retrieved and processed outside the actual work process of the industrial system, which receives and processes the signals in the evaluation electronics.
• a machine condition analysis takes place.
• the system may be configured such that once a week or once a day, the machine tool invokes a special maintenance program and various axis motions, in particular without actual machining, with different rotational speeds of the spindle.
• the physical results, for example by vibration measurement, of this maintenance program are measured by the monitoring system and stored for analysis.
• the sensor is preferably a triaxial sensor, but this is only an example if the diagnosis and analysis are primarily related to the axes of the industrial system. Its signals are passed on to an electronic evaluation unit, in which inventions special algorithms for state detection. Preferably, this evaluation has then also a communication interface with the machine, if necessary, so that the machine control can be influenced. In this way, not only mechanical problems with respect to spindle, guide rails, Rollenlauflauf conception, etc. are detected, but also drive problems, lubrication problems, etc. Above all, the vibration or vibration is monitored. The vibrations are analyzed and evaluated with different algorithms. The evaluation is based on typical vibration patterns, that is, on the basis of many years of experience from machine diagnostics.
• a fingerprint of the machine is created. This means that all determined values of the machines form an overall picture. At regular intervals, this fingerprint of the machine is compared with the current states and analyzed and, if necessary, the fingerprint is also adjusted (learning process).
• the inventive method is also coupled with a system for the continuous control of the industrial system during its use.
• a system for the continuous control of the industrial system during its use.
• collision monitoring is more likely to take place with the process monitoring, the analysis of this collision monitoring then with the condition monitoring.
• both monitors but also take over parts of the other.
• the new method can perform both collision monitoring and the out-off process tasks described above.
• this means that the reaction to the detection of a possible collision is accelerated to one millisecond.
• the invention also encompasses a corresponding device which essentially comprises a sensor, in particular an acceleration sensor, an evaluation unit and preferably an interface for the machine control.
