To set a distance of the friction roller, a piezo actuator is provided.
  • EP 0 242 622 B1 discloses a monitoring device of the type referred to here, which has a scanning roller arranged above a feeder table, which can be displaced in the direction of the feeder table by means of an electric stepping motor.
  • the scanning roller is coupled to a sensor which transmits a signal to a control device whenever at least two arcs overlap one another. It has been found that the monitoring device is of limited use and in those cases where a dynamic and very precise displacement of the cam follower is required, among other things due to the relatively sluggish stepping motor can not be used. It is therefore an object of the invention to provide a monitoring device of the type mentioned, which does not have this disadvantage.
  • Another object of the invention is to provide a method for controlling the arc current, in which a high reliability can be ensured.
  • a monitoring device with the features of claim 1 is proposed. This comprises at least one arranged above or below a sheet flow sensing element which is movable by means of an actuator in the direction of the arc current and away from the arc current.

  • a method with the features of claim 18 proposed in which to control the arc current structure or the Sheet flow during its transport into a sheet processing machine at least a probe element is displaceable in the direction of a counter-pressure element, via which the maruppte or single sheet having arc current out, that is transported.
  • the method is characterized in that the probe element is turned on the arc current, that is pressed with defined force and this during its transfer into the Machine, such as a sheetfed press detected.

  • the path is determined, which the probe element against the preferably fixed, for example, formed by a feeder table Counter-pressure element is displaced. This can very accurately the thickness of the arc current be determined or measured, so that easily double and missing sheet be detected, which leads, for example, to the output of an error signal.
  • the method is characterized by a high accuracy and also has a high reliability. It is also particularly advantageous that due to the constant holding force of the probe element to the counter-pressure element the measurement conditions are constant regardless of the respective arc current thickness. It is Therefore, without further automation of the arc or the Sheet thickness measurement and / or sheet current monitoring possible.
  • the Contact pressure of the probe element is monitored to the arc current and that the over- or Falling below a limit value for the contact force an error signal is triggered, what For example, to a visual display of a fault or immediately to stop the Machine leads.

So, for example, occurs within the Bogenstrom a double arc on, so that at this point the thickness of the arc current is increased inadmissible, the probe element by means of a suitable, preferably dynamic actuator from the back pressure element so far away that the contact pressure of the probe element to the arc current remains at a constant value.

  • the clear distance between the probe element and the arc current is so small that provided a double arc is present in the arc current, it causes a contact between the Double sheet and the feeler comes.
  • This "collision" is in different ways ascertainable, for example by ascertaining when the double arch of the same force exerted on the probe element force. After recognition of the double sheet, the represents a fault in the arc current, an error message is issued, what For example, immediately leads to a stop of the machine.
