Description

Die Erfindung betrifft eine Meßeinrichtung zum Messen eines Greiferauflagedruckes in Bogenrotationsdruckmaschinen.The invention relates to a measuring device for measuring a gripper contact pressure in sheet-fed rotary printing machines.

Der Greiferauflagedruck für alle Greifer einer Greiferreihe eines bogentranpsortierenden Zylinders einer Bogenrotationsdruckmaschine muß möglichst bei allen Greifern gleich groß sein. Stärkere Unterschiede machen sich z.B. in Form von Dublieren bemerkbar. Bisher war es nur möglich, den Greiferauflagedruck über Federwaagen zu messen. - Eine Methode, bei dem es sehr von der Geschicklichkeit des Meßtechnikers abhing, genaue und reproduzierbare Werte zu erhalten.The gripper contact pressure for all grippers in a gripper row of a sheet-transporting cylinder of a sheet-fed rotary printing machine must be as large as possible for all grippers. Stronger differences make for example in the form of D ublieren noticeable. Until now it was only possible to measure the gripper contact pressure using spring scales. - A method in which it was very dependent on the skill of the measurement technician to obtain accurate and reproducible values.

Die Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum Messen eines Greiferauflagedruckes für Greifer in Bogenrotationsdruckmaschinen zu schaffen, mit dem genaue und reproduzierbare Werte für den Greiferauflagedruck ermittelt werden können, ohne von der Geschicklichkeit des Messenden abhängig zu sein.The invention has for its object to provide a device for measuring a gripper contact pressure for grippers in sheet-fed rotary printing presses, with which precise and reproducible values for the gripper contact pressure can be determined without being dependent on the skill of the person measuring.

Diese Aufgabe wird durch den Gegenstand des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the subject matter of the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß ein Meßgerät zur Verfügung steht, mit dem reproduzierbare Werte des Greiferauflagedruckes ermittelt werden können und diese Werte direkt an Registrierstationen weitergegeben werden können, dort abgespeichert und zur Einjustierung der Greiferauflagekräfte verwendet werben können. Es lassen sich leicht Verkantungen der Greifer erkennen.The advantages achieved with the invention consist in particular in the fact that a measuring device is available with which reproducible values of the gripper contact pressure can be determined and these values can be passed on directly to registration stations, stored there and used for adjusting the gripper contact forces can. Tilting of the grippers can be easily recognized.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Seitenansicht im Schnitt der erfindungsgemäßen Meßeinrichtung im Zusammenwirken mit einer Greiferauflage und einer Greiferspitze;
  • Fig. 2 eine schematische Darstellung eines Meßaufbaus;
  • Fig. 3 eine Schaltungsanordnung zur Erfassung mehrerer Greiferauflagedrücke nacheinander;
  • Fig. 4 eine Schaltungsanordnung zur Erfassung und Registrierung der Greiferauflagedrücke mehrerer Greifer.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • Figure 1 is a side view in section of the measuring device according to the invention in cooperation with a gripper pad and a gripper tip.
  • Fig. 2 is a schematic representation of a measurement setup;
  • 3 shows a circuit arrangement for recording several gripper contact pressures in succession;
  • Fig. 4 shows a circuit arrangement for detecting and registering the gripper support pressures of several grippers.

Zwischen einer Greiferspitze 1 eines Greifers auf z.B. einem Gegendruckzylinder und einer metallischen Greiferauflage 2 wird die erfindungsgemäße Meßeinrichtung angeordnet. Die Meßeinrichtung besteht aus einer Isolatorschicht 3, einer Leiterschicht 4 und einer elastischen Trägerschicht 6. Diese drei Schichten sind übereinander angeordnet, wobei zweckmäßigerweise die Leiterschicht 4 die Trägerschicht 6 allseitig überragt und die Isolatorschicht 3 wiederum die Leiterschicht 4 allseitig überragt. Die Isolatorschicht 3 kann z.B. aus Papier bestehen, die Leiterschicht 4 aus Aluminium. Die elastische Trägerschicht 6 kann z.B. aus Schaumgummi bestehen, dessen Poren untereinander Verbindung haben. In diesen Poren ist Graphitstaub eingelagert. Auch sind dünne, plattenförmige Elastomere z.B. Silikonkautschuck mit eingelagertem Leitruß als Trägerschicht 6 anwendbar.The measuring device according to the invention is arranged between a gripper tip 1 of a gripper on, for example, an impression cylinder and a metallic gripper support 2. The measuring device consists of an insulator layer 3, a conductor layer 4 and an elastic carrier layer 6. These three layers are arranged one above the other, the conductor layer 4 expediently projecting over the carrier layer 6 on all sides and the insulator layer 3 in turn projecting over the conductor layer 4 on all sides. The insulator layer 3 can consist, for example, of paper, the conductor layer 4 of aluminum. The elastic carrier layer 6 can consist, for example, of foam rubber, its pores to have connection with one another. Graphite dust is embedded in these pores. Thin, plate-shaped elastomers, for example silicone rubber with embedded conductive carbon black, can also be used as carrier layer 6.

Die Gesamtschichtdicke von Isolatorschicht 3 plus Leiterschicht 4 plus elastischer Trägerschicht 6 beträgt ca. 0,5 mm.The total layer thickness of insulator layer 3 plus conductor layer 4 plus elastic carrier layer 6 is approximately 0.5 mm.

An einem Ende der Leiterschicht 4 ist eine isolierte Anschlußlitze 7 leitend befestigt. An der Greiferauflage 2, auf der die elastische Trägerschicht 6 aufliegt oder an der Trägerschicht 6 selbst ist eine isolierte Anschlußlitze 8 elektrisch leitend befestigt. Zwischen den Anschlußlitzen 7 und 8 kann ein elektrischer Widerstand RM der Trägerschicht 6 gemessen werden. Dieser Widerstand RM ändert sich proportional mit auf die Meßanordnung 3, 4, 6 ausgeübtem Druck, also ist proportional zum Greiferauflagedruck. Je stärker der Greiferauflagedruck, je kleiner der elektrische Widerstand Rm der Meßanordnung 3, 4, 6 (= Sensor 9).At one end of the conductor layer 4, an insulated lead 7 is conductively attached. On the gripper pad 2, on which the elastic carrier layer 6 rests, or on the carrier layer 6 itself, an insulated connecting wire 8 is fastened in an electrically conductive manner. An electrical resistance R M of the carrier layer 6 can be measured between the leads 7 and 8. This resistance R M changes proportionally with the pressure exerted on the measuring arrangement 3, 4, 6, that is to say is proportional to the gripper contact pressure. The stronger the gripper contact pressure, the smaller the electrical resistance R m of the measuring arrangement 3, 4, 6 (= sensor 9).

Die zwei Anschlußlitzen 7, 8 werden z.B. an eine Wheat- stone'sche Meßbrücke (Fig. 2) mit den Brückenwiderständen R1, R2' R3 und RM angeschlossen. R1 ist ein Festwiderstand, R2 und R3 sind Potentiometer. Die Widerstände R1, R2, R3, Rm max. können z.B 500 Ohm betragen.The two connecting strands 7, 8 are connected, for example, to a Wheatstone measuring bridge (FIG. 2) with the bridge resistances R 1 , R 2 ' R 3 and R M. R 1 is a fixed resistor, R 2 and R 3 are potentiometers. The resistors R 1 , R2 , R3 , R m max. can be, for example, 500 ohms.

Die Speisespannung für die Wneatstone'sche Brücke beträgt z.B. 1,5 Volt Gleichspannung. Die Widerstände R1, R2, R3, RM sind im Viereck aneinander geschaltet. Zwischen RM und R3 liegt der Anschlußpunkt A, zwischen R3 und R2 der Anschlußpunkt C, zwischen R2 und R1 der Anschlußpunkt B und zwischen R1 und RM der Anschlußpunkt D. Zwischen die Anschlußpunkte A und B wird ein Galvanometer 10 geschaltet und an die Anschlußpunkte C und D eine Gleichspannungsquelle U. Über die Potentiometer R2 und R3 wird die Meßschaltung abgeglichen (Galvanometerausschlag = Null), wenn der Sensor 9 unbelastet ist. Mit genau definierten Kräften auf den oder die Sensoren 9 lassen sich exakte Eichkurven aufstellen oder abspeichern, so daß danach eine exakte Greiferauflagekraft gemessen werden kann.The supply voltage for the Wneatstone bridge is, for example, 1.5 volts DC. The resistors R 1 , R2 , R 3 , R M are connected to each other in a square. Between R M and R 3 is the connection point A, between R 3 and R 2 the connection point C, between R 2 and R 1 the connection point B and between R 1 and R M the connection point D. Between the connection points A and B there is a galvanometer 10 switched and to the connection points C and D a DC voltage source U. The measuring circuit is adjusted via the potentiometers R 2 and R 3 (galvanometer deflection = zero) when the sensor 9 is not loaded. Exact calibration curves can be set up or stored with precisely defined forces on the sensor (s) 9, so that an exact gripper contact force can then be measured.

In einer Greiferreihe muß für jeden Greifer ein Sensor 9 und eine Wheatstone'sche Brücke (R1, R2, R3, RM) vorhanden sein. Jede der Meßbrücken wird z.B. an einen Meßstellenumschalter 17 angeschloßen und nacheinander aufgeschaltet und der Meßwert abgelesen.A sensor 9 and a Wheatstone bridge (R 1 , R 2 , R 3 , R M ) must be present in a row of grippers for each gripper. Each of the measuring bridges is connected, for example, to a measuring point switch 17 and connected in succession and the measured value is read off.

Aber es ist auch eine Meßanlage (Fig. 4) möglich, in der das Multiplex-Verfahren angewendet wird. Die Meßwerte von der Vielzahl von Sensoren 9 werden über jeweils zugeordnete Meßbrücken 11 (Anschlußpunkte A1 - B1, A2 - B2, ... A 5 - B 5) einem Multiplexer 12 zugeführt. In einem nachgeschalteten Analog/Digitalwandler 13 werden die Analogmeßwerte in Digitalwerte umgewandelt und an einem Prozessrechner 14 abgegeben und anschließend auf einem Bildschirm dargestellt.But a measuring system (FIG. 4) is also possible, in which the multiplex method is used. The measured values from the plurality of sensors 9 are fed to a multiplexer 12 via respectively assigned measuring bridges 11 (connection points A 1 - B 1 , A 2 - B 2 , ... A 5 - B 5 ). In a downstream analog / digital converter 13, the analog measured values are converted into digital values and output to a process computer 14 and then displayed on a screen.
