Abstract
Description
Die Erfindung betrifft eine Sensoreinrichtung für verschmutzungsgefährdete Bereiche in Druckmaschinen.The The invention relates to a sensor device for polluting areas in printing presses.
In Druckmaschinen wird zur Bedruckstoffdurchlaufkontrolle und Funktionsüberwachung von Druckmaschinenaggregaten eine Vielzahl von optischen, magnetischen, induktiven oder kapazitiven Sensoren eingesetzt, deren Funktionssicherheit bzw. Messgenauigkeit durch äußere Verschmutzungen, wie beispielsweise Papierstaub oder Farbaerosole, beeinträchtigt wird.In Printing presses become substrate throughput control and function monitoring of printing presses a variety of optical, magnetic, inductive or capacitive sensors used, their reliability or measurement accuracy due to external contamination, such as For example, paper dust or paint aerosols is impaired.
Es ist bekannt, zur Reinigung optischer Sensoren von anhaftenden Stäuben Blasluftreinigungseinrichtungen an den Sensoren vorzusehen, die allerdings selbst die Gefahr der Verunreinigung der Sensoren in sich bergen, da durch die Blasluftimpulse Staub aus der Umgebung des Sensors aufgewirbelt werden kann oder Schmutzpartikel erst durch die Glaseinrichtung auf den Sensor gelenkt werden und sich am Sensor niederschlagen.It It is known to clean optical sensors of adhering dusts blast air cleaning equipment to provide the sensors, however, even the risk of Pollution of the sensors in itself, because of the blown air pulses Dust from the environment of the sensor can be whirled up or Dirt particles are first directed through the glass device onto the sensor and settle on the sensor.
Aus
der
Der Erfindung liegt die Aufgabe zugrunde, die Reinigung von Sensoren in verschmutzungsgefährdeten Bereichen zu verbessern.Of the Invention is based on the object, the cleaning of sensors in polluting Areas to improve.
Erfindungsgemäß wird die Aufgabe durch eine Sensoreinrichtung mit den Merkmalen des ersten Anspruchs gelöst.According to the invention Task by a sensor device with the features of the first Claim solved.
Die Erfindung hat den Vorteil, dass die Ablagerung von Messwerte verfälschenden Verschmutzungen an den sensitiven Signalein- und -austrittsflächen eines Sensors im Vergleich zu Blasluftreinigungseinrichtungen wesentlich reduziert wird. Aufgrund der intensiven Wechseldruckbeanspruchungen im Ultraschallschwingungsfeld werden die ablagerungsbildenden Adhäsionshaftkräfte der Schmutzpartikel wirksam überwunden. Ein weiterer Vorteil besteht darin, dass bei dauerhafter Aktivierung der Ultraschall-Reinigung bereits die Anlagerung von Schmutzpartikeln an die Sensoroberfläche verhindert wird.The The invention has the advantage that the deposition of measured values falsifies Dirt on the sensitive signal input and output surfaces of a Sensor compared to blown air purification equipment essential is reduced. Due to the intensive alternating pressure stresses In the ultrasonic vibration field, the deposit-forming adhesion adhesion forces of the Effectively overcome dirt particles. Another advantage is that with permanent activation the ultrasonic cleaning already the deposition of dirt particles to the sensor surface is prevented.
Sensoren sind in Druckmaschinen beispielsweise entlang des Bedruckstoffweges zur Kontrolle
- – der Bedruckstoffvereinzelung,
- – der Bedruckstoffausrichtung vor dem Druck oder
- – des zeit- und lagerichtigen Bedruckstofftransportes zu und zwischen den Druckwerken
- - the printing material separation,
- - the printing material orientation before printing or
- - the time and position of the substrate transport to and between the printing units
