Abstract

The equipment monitors the progress of strip material, particularly paper through a printing press, using a light-sensitive receiver irradiated by a light source. The paper (10) passes between a light-sensitive resistance (13), connected via an amplifier (11) to a switch (12) controlling the printing operation, and a light source. The latter is formed by a fibre bundle (15) illuminated by a lamp (14). The amplifier can be a three-stage transistor amplifier, and the bundle can be formed by flexible fibres.

Description

Anordnung zur Überwachung des Laufes von Insbes. Order to monitor the run of esp.

Papierbahnen an Druckmaschinen Anm.: Heinz Walter, 2085 Quickborn Die Erfindung betrifft eine Anordnung zur Überwachung des Laufes von Jarenbahnen, insbes. des Papierlaufes am Faltenbeutelmaschinenkopf, sowie in Verbindung mit Druckmaschinen, bei der ein lichtempfindlicher Empfänger von einer Lichtquelle beaufschlagt wird. Paper webs on printing machines Note: Heinz Walter, 2085 Quickborn The invention relates to an arrangement for monitoring the running of Jarenbahnen, esp. the paper run on the pleated bag machine head, as well as in connection with printing machines, in which a light-sensitive receiver is acted upon by a light source.

Es ist bekannt, insbesondere bogenverarbeitende Rotationsmaschinen mit Reflexmeßvorrichtungen im Maschinentakt zu überwachen, um bei einem Papierriß den Antrieb der Papierbahn abzuschalten und sämtliche Einwirkungen auf das Papier auszuschalten, z.B. c:ie Druckwalzen abzuheben oder den Farbzufluß zu den Druckwalzen zu unterbrecIien und dorpl.It is known, particularly sheet-fed rotary machines with reflex measuring devices in the machine cycle to monitor in the event of a paper tear switch off the drive of the paper web and all effects on the paper off, e.g. c: lift off the printing rollers or the flow of ink to the printing rollers to interrupt and dorpl.

Die bekannten Reflexmeßvorrichtungen wie etwa Lichtschranken benötigen im allgemeinen starke Lichtquellen, welche einen verhaltnismäßig großen Raumbe(,?rf haben. Sie lassen sich dadurch nur unter großen Schwieri keiten in kompakt und en gebauten 1totationsuaschinen mit ihren engen freien Räumen unterbringen. Es ist dadurch hierbei nur möglich eine überwachung in relativ großen Asbtänden, nämlich dort wo gerade ein entsprechender freier Raum verfügbar ist, vorzugnehmen.The known reflex measuring devices such as light barriers need generally strong light sources, which cover a relatively large area (,? rf to have. As a result, they can only be built compactly with great difficulty 1 can accommodate rotation machines with their narrow free spaces. It is thereby here Monitoring is only possible in relatively large volumes, namely wherever adequate free space is available.

Durch die vorliegende Erfindung soll deshalb die Aufgabe gelöst werden, eine Überwachungseinrichtung der genannten Art zu schaffen, die im Bereich der Überwachungsstelle nlatzsparend ausgebildet ist und auch in engsten Räumen angeordnet werden kann.The present invention is therefore intended to solve the problem to create a monitoring device of the type mentioned in the area of the monitoring point Is designed to save space and can also be arranged in the tightest of spaces.

Zur Lösung dieser Aufgabe wird erfindungsgemäß bei einer An ordnung der genannten Art vorgeschlagen, die warenbahn, also insbesondere die Papierbahn, zwischen einem mit einen Schaltverstärker zur Auslösung eines Schaltorganes für die Betätigung einer den Druckvorgang beeinflussenden Einrichtung verbundenem Fotowiderstand und einer Lichtquelle hindurch zu führen, die von einen durch eine Lampe beaufschlagten Faserbündel gebildet wird, welches insbesondere aus flexiblen Fasern bestehen soll. Der Schaltverstärker soll in einer bevorzugten Ausführungsform als 3-stufiger Transistorverstärker ausgeführt sein.To solve this problem, according to the invention in an arrangement proposed of the type mentioned, the web, so in particular the paper web, between one with a switching amplifier to trigger a switching element for the actuation of a photoresistor connected to a device influencing the printing process and to guide a light source through which one is acted upon by a lamp Fiber bundle is formed, which should in particular consist of flexible fibers. In a preferred embodiment, the switching amplifier should be a 3-stage transistor amplifier be executed.

Nachfolgend soll die Erfindung an Hand der Zeichnung, auf der in schematischer Darstellung Fig. 1 die Anordnung an einem Faltenbeutelmaschinenkopf, Fig. 2 den Schaltverstärker und Fig. 1 die Kontaktbelegung des Relais zeigen, noch nöher erläutert werden.The invention is based on the drawing, on which in schematic Representation Fig. 1 the arrangement on a folding bag machine head, Fig. 2 shows the switching amplifier and FIG. 1 shows the contact assignment of the relay in more detail explained.

In Fig. 1 ist die laufende Warenbahn mit 10 bezeichnet, das mit einer Lampe 14 verbundene, als Lichtquelle für den Fotowiderstand 1, dienende Faserbündel 7it 15 unci Cer mit dem Fotowiderstand verbundene auf ein Schaltorgan 12 für einen Antriebsmotor für die Warenbahn oder dergl. einwirkende Schaltverstärker mit 11.In Fig. 1, the running web is denoted by 10, with a Lamp 14 connected, as a light source for the photoresistor 1, serving fiber bundles 7it 15 unci Cer connected to the photoresistor on a switching element 12 for one Drive motor for the material web or the like. Acting switching amplifier with 11.

Für diesen in Fig 2 dargestellten Schalverstärker ist, wie die Figur erkannen lußt, als Spannungsversorgung eine 12 V Gleichspannung erforderlich. Dazu werden die vom Netz gelieferten 220 V Wechselstrom auf 12 V Wechselstrom herabtransformiert und dann gleichgerichtet. Die Absicherung der Schaltung erfolgt durch eine Feinsicherung e auf der Frimärseite des Transformators. Durch einen Schalter S wird das Gerät in Betriebsstellung gebracht.For this sound amplifier shown in Fig. 2 is like the figure A 12 V DC voltage is required as the power supply. In addition the 220 V alternating current supplied by the mains are transformed down to 12 V alternating current and then rectified. The circuit is protected by a microfuse e on the primary side of the transformer. A switch S turns the device brought into operating position.

Um bei schwacher Beleuchtung des Fotowiderstandes die Relaisschaltung zu gewährleisten, ist der Schalverstärker mehrstufig ausgebildet. Die drei Transistoren T1, T2, T3 sind galvanisch gekoppelt. Dabei ist der Transistor T1 gesperrt, wenn der Fotowiderstand 1 ]:ein Li.cht erhält. Transistor T2 ist dabei durchgeschaltet, da er über den Kollektorwiderstand genügend Steuerspannung an der Basis erhält. Der eigentliche Schalttransistor T.. ist wiederum gesperrt, denn er erhält keine Steuerspannung von Transistor T3. Bei Lichteinfall am Fotowiderstand 13, kippen alle drei Transistorstufen in den entgegengesetzten Zustand um, wodurch dann Ti leitend, T2 gesperrt und T leitend ist una das relais Rel tzct t. Die zur Relais Rel parallel geschaltete Diode D verhindert das Entstehen einer unerwünschten hohen Induktionsspanung im Relais, wenn der Schaltstrorn plötzlich arbeißt. Da zur Aussteuerung des Schalterverstärker wenige Mikroampere ausreichend sind, spricht er schon auf eine sehr schwache Beleuchtung des Fotowiderstandes an.To switch the relay circuit in the case of weak lighting of the photoresistor To ensure that the sound amplifier is designed in several stages. The three transistors T1, T2, T3 are galvanically coupled. The transistor T1 is blocked when the photo resistor 1]: a light gets. Transistor T2 is switched on, because it receives sufficient control voltage at the base via the collector resistor. The actual switching transistor T .. is again blocked because it does not receive any Control voltage from transistor T3. When light falls on the photo resistor 13, all three transistor stages flip over into the opposite state, which then Ti is conductive, T2 is blocked and T is conductive and the relay Rel tzct t. The one to relay Rel diode D connected in parallel prevents the occurrence of an undesirable high Induction voltage in the relay when the switching current suddenly starts working. As for level control of the switch amplifier a few microamps are sufficient, it already speaks a very weak illumination of the photo resistor.
