Description

Die Erfindung betrifft eine Schneidvorrichtung für ein Falzwerk einer Druckmaschine mit zwei Schneidzylindern für die senkrecht zugeführte Bahn und nachgeschalteten Transportbandleitungen, die über Umlenkrollen laufen und die abgeschnittenen Produkte zwischen sich weiterführen.The invention relates to a cutting device for a folding unit of a printing press with two cutting cylinders for the vertically fed web and downstream conveyor belt lines, which run over deflection rollers and carry the cut products between them.

Ein derartiges Falzwerk ist aus dem Prospekt "Lithoman M" in der Firma MAN Roland Druckmaschinen AG, Seite 6 bekannt. Bei diesem Falzwerk sind die geschnittenen Produkte auf dem Weg zwischen den Schneidzylindern einerseits und den Transportbändern andererseits ohne Führung. Hierbei ist nachteilig, daß die vorderen Schnittkanten der Produkte dazu neigen, für eine kurze Zeit an den Zähnen des Messers des einen Schneidzylinders haften zu bleiben. Löst sich die Vorderkante etwas verzögert von dem Schneidzylinder, so wird die Richtung in der das abgeschnittene Produkt von den Schneidzylindern abläuft, geändert. Die Vorderkante stößt dann gegen eine Umlenkrolle und bildet beim Einziehen zwischen die Transportbänder abgeknickte Ecken. Ein Haften der Vorderkanten an einen Schneidzylinder kann auch infolge einer elektrostatischen Aufladung auftreten. Derartige Aufladungen können nicht nur ungewollt während des Betriebes auftreten, sie werden vielmehr bei mehrlagigen Bahnen bewußt vorgesehen, um die einzelnen geschnittenen Bogen zusammenzuhalten.Such a folder is known from the brochure "Lithoman M" in the company MAN Roland Druckmaschinen AG, page 6. With this folding unit, the cut products are without a guide on the way between the cutting cylinders on the one hand and the conveyor belts on the other. It is disadvantageous here that the front cutting edges of the products tend to stick to the teeth of the knife of the one cutting cylinder for a short time. If the leading edge detaches from the cutting cylinder with a slight delay, the direction in which the cut product runs off the cutting cylinders is changed. The front edge then abuts a deflection roller and forms kinked corners when it is pulled in between the conveyor belts. The leading edges may also adhere to a cutting cylinder as a result of electrostatic charging. Such charges can not only occur unintentionally during operation, they are rather deliberately provided in multi-layer webs in order to hold the individual cut sheets together.

Der Erfindung liegt die Aufgabe zugrunde eine Führung für die geschnittenen Produkte zwischen den Schneidzylindern und den Transportbändern zu schaffen, die einen exakten Einlauf der Produkte zwischen die Transportbandleitungen sicherstellt.The invention has for its object to provide a guide for the cut products between the cutting cylinders and the conveyor belts, which ensures an exact entry of the products between the conveyor belt lines.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß beiderseits der ankommenden Bahn in den Spalt zwischen Bahn und Schneidzylinder gerichtete Blasdüsen angeordnet und die Schneidzylinder mit Nuten zum Durchtritt der Blasluft parallel zur Bahn versehen sind. Hierdurch wird ein Luftpolster erzeugt, das die geschnittenen Produkte bis in den Einlauf der Transportbandleitungen führt.This object is achieved according to the invention in that blowing nozzles are arranged on both sides of the incoming web into the gap between web and cutting cylinder and the Cutting cylinders are provided with grooves for the passage of the blowing air parallel to the path. This creates an air cushion that leads the cut products into the inlet of the conveyor belt lines.

Vorteilhaft sind zwischen den Umlenkrollen der Transportbandleitungen Saugdüsen zur Absaugung der durch die Nuten durchtretenden Luft angeordnet. Durch diese Maßnahme wird die Bildung eines die abgeschnittenen Produkte führenden Luftpolsters begünstigt, insbesondere werden Verwirbelungen der Luft hinter den Schneidzylindern vermindert.Suction nozzles for extracting the air passing through the grooves are advantageously arranged between the deflection rollers of the conveyor belt lines. This measure favors the formation of an air cushion carrying the cut products, in particular turbulence in the air behind the cutting cylinders is reduced.

Um die Luftführung an Bahnen unterschiedlicher Stärke oder mit einer unterschiedlichen Zahl von Lagen anpassen zu können, sind die Blasdüsen zur Änderung der Ausblaserichtung vorteilhaft einstellbar angeordnet. Zum gleichen Zweck können gemäß bevorzugten Ausführungsformen das Blasluftvolumen und/oder das Saugluftvolumen einstellbar sein.In order to be able to adapt the air flow to webs of different thicknesses or with a different number of layers, the blowing nozzles are advantageously arranged to be adjustable in order to change the direction of the blowing out. For the same purpose, the blown air volume and / or the suction air volume can be adjustable in accordance with preferred embodiments.

Auf der Zeichnung sind zwei Ausführungsbeispiele der Erfindung wiedergegeben. Es zeigt

  • Fig. 1 eine schematische Seitenansicht des Erfindungsgegenstandes,
  • Fig. 2 eine Ansicht von oben in verkleinertem Maßstab und
  • Fig. 3 eine Variante der Schneidzylinderausbildung.
Two exemplary embodiments of the invention are shown in the drawing. It shows
  • 1 is a schematic side view of the subject of the invention,
  • Fig. 2 is a top view on a reduced scale and
  • Fig. 3 shows a variant of the cutting cylinder training.

Die Anordnung gemäß Fig. 1 und 2 weist zwei Schneidzylinder 1, 2 auf, von denen der eine zwei Messer 3 trägt, während der andere mit entsprechenden nachgiebigen Wiederlagern 4 versehen ist. Zwischen den beiden Schneidzylindern 1, 2 werden von einer senkrecht von oben in Richtung des Pfeiles a einlaufenden Bahn 5 Produkte abgeschnitten. Diese Produkte werden von Transportbandleitungen 6, 7 erfaßt und in Richtung des Pfeiles b weitergeleitet. Die Transportbandleitungen 5, 6 bestehen aus mehreren schmalen Bändern, die über Umlenkrollen z.B. 8, 9 geführt und in an sich bekannter, nicht näher dargestellter Weise angetrieben sind.The arrangement according to FIGS. 1 and 2 has two cutting cylinders 1, 2, one of which carries two knives 3, while the other is provided with corresponding flexible bearings 4. Between the two cutting cylinders 1, 2, 5 products are cut off from a web that runs vertically from above in the direction of arrow a. These products are detected by conveyor belt lines 6, 7 and passed on in the direction of arrow b. The conveyor belt lines 5, 6 consist of several narrow belts, which are guided over deflection rollers, for example 8, 9, and are driven in a manner known per se, not shown in detail.

Beiderseits der ankommenden Bahn 5 sind mehrere insgesamt mit 10 bzw. 11 bezeichnete Blasluftdüsen angeordnet. Die nebeneinander angeordneten Blasluftdüsen 10 werden mittels einer Luftzuleitung 12 und die nebeneinander angeordneten Blasluftdüsen 11 mittels einer Luftzuleitung 13 mit Druckluft versorgt. Zweckmäßig weist jede Blasluftdüse z.B. 10 eine Schelle 14 auf, die mittels einer nur schematisch angedeuteten Schraube 15 in unterschiedlichen Winkellagen auf der Luftzuleitung 12 festgelegt werden kann.On both sides of the incoming web 5, a plurality of blowing air nozzles, generally designated 10 or 11, are arranged. The side-by-side blowing air nozzles 10 are supplied with compressed air by means of an air supply line 12 and the side-by-side blowing air nozzles 11 are supplied with compressed air. Each blowing air nozzle expediently has e.g. 10 a clamp 14 which can be fixed in different angular positions on the air supply line 12 by means of a screw 15 which is only indicated schematically.

Hierdurch besteht die Möglichkeit, die Richtung mit der der Druckluftstrom aus den Blasdüsen 10, 11 in den Spalt zwischen der Bahn 5 und dem jeweiligen Schneidzylinder 2 bzw. 3 eintritt einzustellen. Die Blasluftdüsen können auch fest mit den Luftzuleitungen verbunden sein. Dann sind die Luftzuleitungen drehbar zu lagern.This makes it possible to set the direction in which the compressed air flow from the blowing nozzles 10, 11 enters the gap between the web 5 and the respective cutting cylinder 2 or 3. The blowing air nozzles can also be firmly connected to the air supply lines. Then the air supply lines must be rotatably supported.

Die Luftzuleitungen 12, 13 sind an einen nicht dargestellten bekannten Drucklufterzeuger angeschlossen. In jeder der beiden Leitungen ist zwischen dem Drucklufterzeuger und den Blasluftdüsen 10, 11 je ein Ventil 16, 17 angeordnet. Mit dem Ventil kann das zu den Blasluftdüsen 10, 11 durchtretende Blasluftvolumen eingestellt werden, um sowohl eine Anpassung an einlagige Bahnen verschiedener Stärke als auch an Bahnen aus mehreren Lagen zu ermöglichen. Alternativ könnte auch jeder Luftzuleitung 12, 13 eine eigene, hinsichtlich des Blasluftvolumens regelbare Pumpe zugeordnet werden.The air supply lines 12, 13 are connected to a known compressed air generator, not shown. A valve 16, 17 is arranged in each of the two lines between the compressed air generator and the blown air nozzles 10, 11. With the valve, the blowing air volume passing through to the blowing air nozzles 10, 11 can be adjusted in order to enable both adaptation to single-layer webs of different thicknesses and to webs from several layers. Alternatively, each air supply line 12, 13 could be assigned its own pump, which can be regulated with regard to the blown air volume.

In den Schneidzylindern 1, 2 sind mehrere Nuten 18, 19 eingeschnitten, die in Umfangsrichtung verlaufen. Durch die Nuten tritt die Blasluft etwa parallel zur Laufrichtung der Bahn 5 durch und bildet somit beiderseits der Bahn 5 Luftpolster, die die abgeschnittenen Produkte in Richtung zu den Transportbandleitungen 6, 7 führen. Die Nuten 18, 19 sind im Bereich der Blasluftdüsen 10, 11 angeordnet.A plurality of grooves 18, 19 are cut in the cutting cylinders 1, 2 and run in the circumferential direction. The blowing air passes through the grooves approximately parallel to the running direction of the web 5 and thus forms air cushions on both sides of the web 5, which guide the cut products in the direction of the conveyor belt lines 6, 7. The grooves 18, 19 are arranged in the area of the blowing air nozzles 10, 11.

Wie Fig. 3 zeigt, können auch Schneidzylinder 20 Verwendung finden, in die eine spiralförmig umlaufende Nut 21 zur Luftführung eingeschnitten ist.As FIG. 3 shows, cutting cylinders 20 can also be used, into which a spiral groove 21 for air guidance is cut.

Unterhalb der Schneidzylinder 1, 2 sind zwischen den Umlenkrollen 8, 9 für die Transportbandleitungen 6, 7 Saugdüsen 22, 23 angeordnet. Die Saugdüsen 22, 23 können, wiederum in ihrer Winkellage einstellbar, mittels Schellen 24, 25 auf Luftableitungen 26, 27 befestigt sein. Die Luftableitungen 26, 27 sind an eine gemeinsame luftansaugende Pumpe angeschlossen. Es kann jedoch auch jeder der beiden Luftableitungen eine eigene Saugpumpe zugeordnet sein. Weiterhin besteht auch hier die Möglichkeit, ebenso wie bei den Luftzuleitungen 12, 13 das Saugluftvolumen durch einstellbare Ventile oder einstellbare Saugluftpumpen zu verändern.Below the cutting cylinders 1, 2, suction nozzles 22, 23 are arranged between the deflection rollers 8, 9 for the conveyor belt lines 6, 7. The suction nozzles 22, 23, again adjustable in their angular position, can be fastened on air discharge lines 26, 27 by means of clamps 24, 25. The air discharge lines 26, 27 are connected to a common air-sucking pump. However, each of the two air discharge lines can also be assigned its own suction pump. Furthermore, there is also the possibility, as with the air supply lines 12, 13, of changing the suction air volume by means of adjustable valves or adjustable suction air pumps.

Im Betrieb strömt die aus den Blasluftdüsen 10, 11 austretende Druckluft durch die Nuten 18, 19 bzw. 21 durch und bildet hinter der engsten Stelle zwischen den Schneidzylindern 2, 3 ein Luftpolster. Hierdurch wird zum einen eine Vorderkante der Bahn 5 daran gehindert, an einem Schneidzylinder 2, 3 haften zu bleiben. Zum anderen wird die Bahn 5 entlang der Solllinie zwischen die Transportbandleitungen 6, 7 geführt. Besteht die Bahn 5 aus mehreren Lagen, so werden diese zusätzlich zusammengehalten. Die Saugluftdüsen 22, 23 wirken dabei einem möglichen Aufreißen des Luftpolsters dadurch entgegen, daß ein weitgehend geradliniger Luftfluß von den Nuten 18, 19 der Schneidzylinder 2, 3 bis zu den Umlenkrollen 8, 9 erzwungen wird.In operation, the compressed air emerging from the blown air nozzles 10, 11 flows through the grooves 18, 19 and 21 and forms an air cushion behind the narrowest point between the cutting cylinders 2, 3. On the one hand, this prevents a leading edge of the web 5 from adhering to a cutting cylinder 2, 3. On the other hand, the web 5 is guided along the desired line between the conveyor belt lines 6, 7. If the web 5 consists of several layers, these are additionally held together. The suction air nozzles 22, 23 counteract a possible tearing of the air cushion by forcing a largely straight air flow from the grooves 18, 19 of the cutting cylinders 2, 3 to the deflection rollers 8, 9.
