Description
Lichtelektrische MesseinrichtungPhotoelectric measuring device
Die Erfindung betrifft eine lichtelektrische Messeinrichtung zur wertmaessigen Erfassunq einer Lage einer Kante eines Bogens auf einer Flaeche einer Bogenrotationsdruckmaschine.The invention relates to a photoelectric measuring device for measuring the value Detection of a position of an edge of a sheet on a surface of a sheet-fed rotary printing press.
Derartige Finrichtunqen sind z. Bo durch die DE-OS 26 59 469 bekannt geworden.Such Finrichtunqen are z. Bo from DE-OS 26 59 469 known become.
Der Erfindung liegt die Aufgabe zugrunde, eine Messeinrichtung zur wertmaessigen Erfassung der Lage einer Kapte eines Bogens auf einem Gegenstand, z. B. eines Anlegebleches, einer Bogenrotationsdruckmaschine zu schaffen hierbei soll eine Messung der Laqe der Boqenkansce auf mindestens 0,01 n genau moeglich sein, und ausserdem soll jedes Messinkrement fuer sich digital auswertbar sein Die mit der Erfindung erzielbaren Vorteile bestenen insbesondere darin, dass jedes Messinkrement fuer sich allein digital auswertbar ist. Hierdurch ist eine einfache und genaue Messung und Auswertung der Lage des Bogens auf z. B. einem Anlegetisch moeglich. Ferner sind Umformeinrichtungen nicht notwendig, um einen digitalen Messwert aus einem analogen zu erhalten.The invention is based on the object of a measuring device for Valuable recording of the position of a cape of a bow on an object, z. B. to create a contact plate, a sheet-fed rotary printing press here a measurement of the length of the Boqenkansce should be possible to an accuracy of at least 0.01 n be, and in addition, each measurement increment should be digitally evaluable for itself The advantages that can be achieved with the invention are in particular that each measurement increment can be evaluated digitally on its own. This makes it easy and accurate Measurement and evaluation of the position of the sheet on z. B. a feed table possible. Furthermore, conversion devices are not necessary in order to generate a digital measured value to get an analog.
Pin Ausfuehrungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden naeher beschrieben. Es zeigen Fig. 1 ein Anlegeblech einer Bogenrotationsdruckmaschine mit er erfindungsgemaessen Einrichtung, Fig. 2 einen Schnitt SI-TI durch iq, 1.Pin exemplary embodiment of the invention is shown in the drawing and is described in more detail below. 1 shows a contact plate of a Sheet-fed rotary printing machine with a device according to the invention, FIG. 2 a Section SI-TI through iq, 1.
In einerr Anleqeblech 1 ist ein rechteckiger Ausbruch 2 von ca 30 r.m Laenge und 5 mm Breite sauer zur Bogenlaufrichtunq ausgestanzt. Dieser Ausbruch 2 dient zur Aufnahme einer Messeinrichtung 3, welche zur Messung der Seitenkantenlage eines (nicht dargestellten) Bogens auf dem Anlegeblech 1 dient Messeinrichtufng 3 besteht aus einer Vielzahl von mindestens in einer Reihe dicht an dicht liegenden Lichtleitfasern 5. Diese Lichtleitfasern 5 sind in eine Kunststoffmasse 6 eingegossen und kennen so bequem am Anlegblech 1 verschraubt werden, dass sie in den Ausbruch 2 hineinragen Die Stirnflaechen 7 der Lichtleitfasern 5 koennen gemeinsam ueberschliffen werden, so dass sie eine vollkommen plane rlaeche bilden. Oberhalb in einem Abstand a von ca. 50 mm der Stirnflaechen 7 der Lichltleie fasern 5 ist ein Lichtgeher 8 angebracht.In a lay-on plate 1 there is a rectangular cutout 2 of approx. 30 r.m length and 5 mm width punched out acidic to the sheet running direction. This outbreak 2 is used to accommodate a measuring device 3, which is used to measure the side edge position a (not shown) sheet on the contact plate 1 is used Messeinrichtufng 3 consists of a large number of at least one row close together Optical fibers 5. These optical fibers 5 are cast in a plastic compound 6 and know that they can be screwed to the support plate 1 so easily that they can be screwed into the breakout 2 protrude The end faces 7 of the optical fibers 5 can be ground together so that they form a perfectly flat surface. Above at a distance a of approx. 50 mm of the end faces 7 of the Lichltleie fibers 5 is a light walker 8 appropriate.
Vom Lichtgeber 8 tritt z. B. monochromatisches Licht 9 aus und trifft auf die Stirnflaechen 7 der Lichtleitfasern 5.From the light transmitter 8 occurs z. B. monochromatic light 9 and hits onto the end faces 7 of the optical fibers 5.
Von diesen wird das Licht 9 aufgenommen und ueber Lichtleitfasern 5 auf Auswerteinheiten 10 geleitet. Jede Lichtleitfaser 5 endet in einer Auswerteinheit 10. Diese kann z. B.The light 9 is received by these and via optical fibers 5 routed to evaluation units 10. Each optical fiber 5 ends in an evaluation unit 10. This can z. B.
aus einer Fotodiode mit angekoppeltem Verstaerker bestehen.consist of a photodiode with a coupled amplifier.
Der Verstaerker kann mit einer ASppstufe versehen sein so dass je nachdem ob Licht 9 auf die Stirnflaeche 7 einer Lichtleitfaser 5 auftrifft oder nicht, am Verstaerkerausqanq ein L- oder Null-Signal ansteht. Dieses Signal ann dann einzeln oder in Verbindung mit einer Zaehlschaltung ausqewertet werden Die Lichtleitfaserdurchmesser d werden zweckaessig entsprechend den qewuenschten Messinkrementen geweehlt.The amplifier can be provided with an A-stage so that each after whether light 9 strikes the end face 7 of an optical fiber 5 or not, there is an L or zero signal at the amplifier output. This signal ann can then be evaluated individually or in conjunction with a counter circuit Optical fiber diameters d are expediently according to the desired measuring increments chosen.
So wird man zweckmaessigerweise bei einem qewuenschten Messwertinkrement von 0,01 mm eine Lichtleitfaser waehlen, deren Durchmesser 0,01 mm betraeqt.This is how one becomes expediently with a desired measured value increment of 0.01 mm choose an optical fiber with a diameter of 0.01 mm.
