Definitions

  • the invention relates to a method for controlling at least one electric motor on an offset printing press with a speed setpoint specification.
  • Speed control is an important application. Your goal is to set and maintain a speed of the electric motor determined by a setpoint value as precisely as possible. This speed setpoint specification can be given, for example, using a potentiometer (see: Zach, Franz; power electronics: components, power circuits, control circuits, influences; Springer Verlag Vienna, New York, 1979).
  • Such drive controls on printing presses are also subject to certain requirements regarding the properties of the power supply, the cooling of the assemblies and the load conditions (cf.for this: interne Elektricticians-Gesellschaft AEG-Telefunken; Aid Book of Electronics, Berlin, Frankfurt, 1979 ; Kolb, Otto, Stromrichtertechnik, vol. 1, AT Verlag, Aarau, Stuttgart, 1984; Hartel, Walter; Stromrichterscloc, Springer-Verlag, Berlin, Heidelberg, New York, 1977). If these requirements are not met, malfunctions that affect the printing result, but at least undesirable downtimes of the printing machines, are to be expected.
  • the invention has for its object to develop a method which ensures the maintenance of the production of the printing press under boundary conditions such as undervoltage, increased ambient or engine temperatures and increased torque requirements with the highest possible printing performance.
  • the object is achieved by the characterizing part of claim 1.
  • the drive of the printing press had to be switched off even if the tolerance range of the mains voltage of the supply network was not exceeded.
  • the speed control according to the invention the production of the printing press can be maintained in a so-called emergency operation.
  • Another advantage of the invention is that the temperature of the electric motor is measured, and if the temperature is exceeded, the speed setpoint of the electric motor is reduced. In the case of drives in printing presses whose torque characteristic drops as the speed decreases, it is possible to maintain the production of the printing press by lowering the speed, even when the ambient temperature and / or the cooling capacity of the electric motor's cooling capacity is greatly reduced. This eliminates the need to switch off these modules when the limit temperature is reached.
  • the temperature of the control elements of the electric motor is advantageously measured and, if the temperature is exceeded, the speed setpoint of the electric motor is reduced. Reduced cooling capacity of the cooling units of the control elements can thus be counteracted by lowering the speed setpoint and a temporary cessation of the printing operation can be prevented.
  • the armature current of the motor is detected and, when a predetermined current limit value is reached, the armature voltage is reduced so that the armature current does not increase any further.
  • the drive torque is preferably detected at those points that cause a power flow, for. B. on drive shafts of electric motors or in such places that are safe to protect against overload, z. B. dampening systems or other consumers, whose torque requirement depends on the handling of the operator.
  • the speed setpoint can advantageously be reduced by the above-mentioned influencing variables or a combination of these influencing variables.
  • the determining influencing variable is the one that has the greatest influence on the speed setpoint.
  • FIG. 1 contains, in addition to reference numerals, also word details about the meaning of the individual elements contained in FIG. 1.
  • Fig. 1 shows the process steps that are necessary to meet all the claimed features of the device.
  • a speed setpoint 2 in the form of a voltage 1 U target 2 is predefined for the drive. This speed setpoint 1 U should 2 is linearly related to the desired speed of the driving electric motor.
  • the counter reading of the counter is set to "zero". This counter is only used to explain the process steps in the flow chart.
  • query 4 the counter reading is checked.
  • step 8 If the supply voltage of the drive is less than this product, which is Drehieresollwertspannun g of 2 U to be formed 7 / k is a product of the measured mains voltage U N and the factor. 1 This ensures that the maximum permissible armature voltage of the electric motor 31 is not exceeded in the event of undervoltage. This is followed by step 8.
  • step 8 If the measuredgessspan- in deciding 6 then g is not less than the product of k and 1 U 'is intended to 2 U 7 set to the same amount as 1 U soll. This is followed by step 8 .
  • step 8 the counter reading is increased by 1, then the output 2, the setpoint 2 U set 7, is output in output 9 and passed on to the speed controller assembly 23. 3 ", the counter reading is queried again at query 4. Since the counter reading is "1" at this point in time, ie not equal to "0", reference is made to decision 15, in which the counter is queried for the counter reading "1".
  • step 8 Since the count is now "1", the measurement is carried out 11 of the temperature T, and on exceeding the maximum Grenztem- perature T max. (Query 12), the setpoint voltage 2 U set 7 is adapted in accordance with the permissible limit temperature in method step 13. This is followed by step 8.
  • setpoint voltage 2 U set 7 is set to the same amount as 1 U set 2 . This is followed by method step 8, in which the counter reading is increased by "1". In the following edition 9, the setpoint 2 U soll 7 is output.
  • step 17 the setpoint voltage 2 U set 7 is reduced in method step 13 by a fixed amount, which is dependent, among other things, on the torque characteristic of the present load. This is followed by step 8.
  • 2 U target 7 is set to the same amount as 1 U target ⁇
  • step 8 the counter reading is increased by "1".
  • the setpoint 2 U soll 7 is output.
  • the setpoint voltage 2 U soll 7 is the lowest value after a complete run in output 9 and is held for a further run.
  • FIG. 2 shows a schematic illustration of the drive control with a device for changing the speed of the electric motor 31-.
  • the mains voltage U N 32 supplies the electric motor 31 via the converter 33.
  • the motor speed is measured via the tachometer generator 22, which is mechanically connected to the motor shaft of the electric motor 31, not shown.
  • the tachometer generator 22 generates the actual speed value and provides this to the speed controller module 23, which forms the comparison between the setpoint 21 and this actual speed value and supplies an output signal of the current controller module 26 corresponding to the desired control behavior.
  • the current regulator assembly 26 forms the control signal for the converter 33.
  • the claimed device 18 receives the setpoint 1 U soll 19 as an input variable.
  • the output variable 2 U soll 21 is formed in the device 18 and is available to the speed controller module 23 as a setpoint input variable . posed.
  • Relevant influencing variables for the output variable 2 U should be 21 , U N , U and UM (N stands for mains, T stands for temperature, M stands for torque).
  • the setpoint 1 U soll 19 is formed by a setpoint processing, not shown, which in the simplest case z . B. can be a potentiometer.
  • the setpoint 1 U soll 19 corresponds to the value of the desired engine speed.
  • the input variable Um is generated by a temperature signal conditioning unit 20.
  • the measuring voltage generated by a thermocouple for example, is amplified and adapted to a corresponding voltage level.
  • the input variable U M is generated with the aid of the same current transformer 25, which supplies the actual current value for the current regulator module 26.
  • the solid characteristic curve 27 represents the course of 2 U target when the supply voltage, the temperature of the drive elements and the moment load are within the permissible range.
  • the dashed curves 28, 29, 30 show the course of 2Usoll, if one of the above conditions is not met. Depending on the size of the deviations, as described, there are different limits for the characteristic curves 28, 29, 30 of 2 U
  • An optical and / or acoustic warning message which indicates the fulfillment of one of the aforementioned features, is within the scope of the invention, as is the possibility of being able to lower the setpoint manually after a warning message.
