Definitions

  • the present invention relates to a method and apparatus for analyzing the energy consumption of machines. More recently, there has been an increasing demand for systems that reduce the power consumption of machines. Thus, it has long been known from the prior art to provide electricity meters which detect the energy consumption of an entire system. However, these current measuring devices have the disadvantage that they make no reference to the actual machine sequence, to procedures, to the tools, to main or auxiliary times and the like allow, but only spend a somewhat averaged consumption value.
  • the present invention is therefore based on the object to enable a more accurate analysis of machines in terms of their energy consumption. This is inventively achieved by a method according to claim 1 and an apparatus according to claim 11. Advantageous embodiments and further developments are the subject of the dependent claims.
  • a multiplicity of data is initially recorded, which are characteristic of a plurality of partial sequences of a workflow of the machine. Furthermore, a variety of data is recorded that is characteristic of the power consumption of the machine. Furthermore, the data that is characteristic of the sub-processes of the machine and also the data that is characteristic of the power consumption of the machine, stored in a memory device. Furthermore, the energy consumption is determined and displayed from the data recorded in the storage device, wherein the energy consumption for at least two sub-processes is separately represented or displayed.
  • the inventive method allows a detailed representation of energy consumption of the machine, not only the total consumption of the machine is issued, but a division, for example, in different sub-processes or different working units of this machine is possible.
  • the data or quantities which are characteristic for the energy consumption of the machine are measured by means of sensor devices.
  • the invention it is possible to record the energy consumption of machines with a concrete relation to a mechanical process, to graphically display and consequently to reduce this energy consumption, this being possible both in manual and in automated form.
  • Such energy recording and analysis methods are not known in the field of automation.
  • the data characteristic of the energy consumption is compared with reference data.
  • the measured characteristic data such as the motor currents
  • nominal currents in order thus to conclude an increased energy consumption.
  • mechanical quantities for determining the energy consumption can also be measured. Two different partial sequences may, for example, be two different method steps of a method.
  • a value representative of the comparison between the characteristic data and the reference data is output. In this way, the user is shown whether the measured energy consumption is equal to, or higher than, an expected value, for example.
  • Tool change times to set and this can be done in particular in graphical form.
  • work instructions are issued based on performed comparisons. It becomes possible, for example, to automatically analyze the data measured and stored in the memory device and to give suggestions to a user as to how energy savings can be achieved. It would also be possible to provide self-optimization of consumption.
  • the machine is controlled or regulated taking into account the data characteristic of the power consumption. More specifically, it is possible to optimize individual sub-processes based on the data obtained. For example, it can be determined by means of a control for a coolant pump that it has a relatively high energy consumption. On the other hand, it would be possible to reduce the power consumption of this coolant pump without at the same time impairing the process to be carried out with the machine. In this way, this energy consumption can be reduced by a precise analysis of the energy consumption and subsequent concrete measures.
  • the quantities to be measured are for example, motor currents, motor voltages, motor torque, rotational speed of an engine, and the like.
  • the sub-processes are temporal subsections of the workflow.
  • an entire run is divided temporally with respect to different process sections and these individual sections are analyzed with regard to their energy consumption.
  • sub-sequences are characteristic processes for different tools of the machine. This means that, for example, several
  • Drives of a machine can be analyzed exactly with regard to their energy consumption and in this way energy-intensive units of the machine can be identified. Furthermore, it is possible to determine the energy consumption over time, in which case a reference to the sequence program is possible, as well as this can be done without reference to the sequence program. It is also possible to observe the energy consumption over the path, for example via the path of a particular tool element with or without reference to a sequence program. As mentioned, however, the energy consumption can also be differentiated according to the respective tool or also according to the respective time type, for example the presence of a main time, an idle time, a tool change time, a workpiece change time, an operating time and the like. Also, the power consumption with respect to the control channels can be observed separately.
  • the representation of the energy consumption can be made in a variety of diagram types, such as in the context of a bar chart or a pie chart. Furthermore, it is possible that the analysis is done using the Internet. For example, a machine user at a certain location could store the data characteristic for the energy consumption and access the database for the evaluation of this data via the Internet, in which, for example, data from a data sheet is stored.
  • the data which is characteristic of several sub-sequences of a workflow of the machine and the data which is characteristic of a power consumption of the machine are repeatedly recorded and stored.
  • the energy data could be cyclically (e.g., weekly) recorded, stored and processed over a longer period of time. In this way, e.g. by outputting a trend graph) early damage of the components can be detected and thus condition monitoring is possible.
  • three measurements or recordings of energy-relevant data of individual components could be carried out, with the corresponding machine being switched on during a first measurement but no movement taking place, in a further measurement the machine is operating without a workpiece (ie traveling in the air) and at one third measurement the machine processes a workpiece.
  • the energy for the process can be deduced by subtracting the energy determined during the second measurement from the energy determined during the third measurement. It is also possible to deduce the energy for the machine movement by subtracting the energy determined during the first measurement from the energy determined during the second measurement.
