In
Deshalb liegt der Erfindung die Aufgabe zugrunde, ein auch zum Bremsen von schweren Druckbogen bei hohen Maschinengeschwindigkeiten geeignetes Bogenbremsensystem zu schaffen.The invention is therefore based on the object to provide a suitable also for braking heavy sheets at high machine speeds sheet brake system.
Diese Aufgabe wird durch ein Bogenbremsensystem mit den Merkmalen des Anspruchs 1 gelöst. Das erfindungsgemäße Bogenbremsensystem zum Bremsen von Druckbogen, umfassend in einer Reihe angeordnete Bogenbremsen mit zueinander verfahrbar angeordneten Modulträgern zum Tragen von Bremsmodulen, die an und von den Modulträgern an- und abkoppelbar ausgebildet sind, ist dadurch gekennzeichnet, dass in einer Betriebsart an einem der Modulträger zwei der Bremsmodule angekoppelt sind.This object is achieved by a sheet brake system having the features of claim 1. The sheet brake system according to the invention for braking printed sheets, comprising arranged in a row sheet brakes with mutually movable arranged module carriers for supporting brake modules, which are formed on and from the module carriers and decoupled, characterized in that in one mode on one of the module carrier two of the brake modules are coupled.
Durch die Doppelbestückung des Modulträgers mit den Bremsmodulen erhöht sich die Gesamtkontaktfläche des beim Bremsen des Druckbogens wirksamen Kontaktes zwischen dem Bogenbremsensystem und dem Druckbogen. Aufgrund der größeren Gesamtkontaktfläche kann eine größere Bremskraft vom Bogenbremsensystem auf den Druckbogen übertragen werden. Deshalb ist das erfindungsgemäße Bogenbremsensystem zum Bremsen von Druckbogen hoher Grammatur, wie z. B. schweren Kartonbogen, bei hohen Maschinengeschwindigkeiten gut geeignet. Ein Zusatzvorteil ist in der guten Eignung des erfindungsgemäßen Bogenbremsensystems zum Bremsen von berührungsempfindlichen Druckbogen, wie z. B. mattgestrichenen Papierbogen und z. B. Druckbogen mit noch feuchter Farbe auf der dem Bogenbremsensystem zugewandten Bogenunterseite, zu sehen. Aufgrund der vergrößerten Gesamtkontaktfläche kann der Saugluft-Unterdruck, mittels welchem das Bogenbremsensystem den Druckbogen ansaugt, reduziert werden. Dadurch verringert sich die Gefahr von durch das Bogenbremsensystem hervorgerufenen Markierungen auf den Druckbogen. Die Verdoppelung der Bremsmodule ist auch hinsichtlich der Vermeidung eines Durchhanges des Druckbogens zwischen den Bogenbremsen und hinsichtlich der Vermeidung einer Wellenbildung des Druckbogens vorteilhaft, was insbesondere für die Verarbeitung von dünnen Papieren wichtig ist.The double assembly of the module carrier with the brake modules increases the total contact surface of the effective during braking of the sheet contact between the sheet brake system and the sheet. Due to the larger total contact area, a greater braking force can be transmitted from the sheet brake system to the signature. Therefore, the sheet brake system according to the invention for braking sheets of high grammage, such. B. heavy cardboard sheet, well suited at high machine speeds. An additional advantage is the good suitability of the sheet brake system according to the invention for braking touch-sensitive sheet such. As matte coated paper sheet and z. B. sheet with still wet paint on the sheet brake system facing bow underside to see. Due to the increased total contact area of the vacuum suction, by means of which the sheet brake system sucks the sheet, can be reduced. This reduces the risk of caused by the sheet brake system marks on the sheet. The doubling of the brake modules is also advantageous in terms of avoiding sagging of the signature between the sheet brakes and in terms of avoiding waviness of the signature, which is particularly important for the processing of thin papers.
In den Unteransprüchen sind vorteilhafte Weiterbildungen des erfindungsgemäßen Bogenbremsensystems genannt.In the dependent claims advantageous developments of the sheet brake system according to the invention are mentioned.
Bei einer Weiterbildung sind die beiden Bremsmodule auf zueinander entgegengesetzten Seiten des Modulträgers an diesen angekoppelt. In diesem Zusammenhang ist es vorteilhaft, wenn die beiden Bremsmodule zueinander spiegelsymmetrisch ausgebildet sind.In a further development, the two brake modules are coupled to each other on opposite sides of the module carrier to this. In this context, it is advantageous if the two brake modules are mirror-symmetrical to each other.
Bei einer weiteren Weiterbildung sind die beiden Bremsmodule an ein Mehrwegeventil angeschlossen, über welches die Bremsmodule vakuumbeaufschlagt sind. Über das Mehrwegeventil wird die Saugluft von den Bremsmodulen abgesaugt, mittels welcher Saugluft die Bremsmodule den Druckbogen an die Bogenbremse ansaugen. Die Beaufschlagung der Bremsmodule über das Mehrwegeventil ist auch hinsichtlich einer einfachen Umrüstung des Bogenbremsensystems von einer Betriebsart auf die andere vorteilhaft. Beispielsweise lässt sich das Bogenbremsensystem einfach und schnell von einem reinen Schöndruckbetriebsmodus auf einen Schön- und Wiederdruckbetriebsmodus umrüsten, wenn das Bogenbremsensystem Bestandteil einer Perfektor-Druckmaschine ist. Das Mehrwegeventil ermöglicht eine alternative Betriebsart, in welcher an dem Modulträger nur ein einziges der Bremsmodule angekoppelt ist. Beim Umrüsten des Bogenbremsensystems von der eingangs genannten Betriebsart auf die alternative Betriebsart wird von dem Modulträger eines der beiden Bremsmodule abgekoppelt und wird mittels des Mehrwegeventils ein am Modulträger für das abgekoppelte Bremsmodul vorgesehener Saugluftanschluss deaktiviert, so dass durch letzteren keine Fehlluft angesaugt wird. Hinsichtlich einer kompakten Bauweise ist es vorteilhaft, wenn das Mehrwegeventil in den Modulträger integriert ist. Hinsichtlich der Integration des Mehrwegeventils in den Modulträger ist es vorteilhaft, wenn das Mehrwegeventil einen zum Schalten drehbar gelagerten Ventilkörper umfasst.In a further development, the two brake modules are connected to a multi-way valve, via which the brake modules are vacuum-loaded. About the multi-way valve, the suction air is sucked from the brake modules, by means of which suction the brake modules suck the sheet to the sheet brake. The loading of the brake modules via the multi-way valve is also advantageous in terms of a simple conversion of the sheet brake system from one mode to another. For example, the sheet brake system can be easily and quickly converted from a pure letterpress mode to a fine and re-press mode of operation when the sheet brake system is part of a perfector press. The multiway valve allows an alternative mode in which only a single one of the brake modules is coupled to the module carrier. When retrofitting the sheet brake system from the aforementioned operating mode to the alternative mode of operation, one of the two brake modules is decoupled from the module carrier and a suction air connection provided on the module carrier for the uncoupled brake module is deactivated by means of the multiway valve, so that no faulty air is sucked in by the latter. With regard to a compact design, it is advantageous if the multi-way valve is integrated in the module carrier. With regard to the integration of the multi-way valve in the module carrier, it is advantageous if the multi-way valve comprises a valve body rotatably mounted for switching.
Bei einer weiteren Weiterbildung sind in der eingangs genannten Betriebsart an einem weiteren der Modulträger zwei weitere der Bremsmodule angekoppelt. Vorzugsweise ist in dieser Betriebsart jeder Modulträger des Bogenbremsensystems mit einem Bremsmodul-Duo bestückt.In a further development, two further of the brake modules are coupled in the aforementioned mode to another of the module carrier. Preferably, in this mode, each module carrier of the sheet brake system is equipped with a brake module duo.
Bei einer weiteren Weiterbildung umfassen die Bremsmodule umlaufende Bremselemente, bei welchen es sich z. B. um um ihre Rotationsachse umlaufende Saugscheiben handeln kann. Vorzugsweise sind die Bremselemente endlose Bremsbänder oder -riemen.In a further development, the brake modules comprise circumferential brake elements, in which it is z. B. can act around its axis of rotation rotating suction discs. Preferably, the brake elements are endless brake bands or belts.

Demgemäß ist das Mehrwegeventil 22 der unbestückten mittleren Bogenbremse 5c in eine Schaltstellung gedreht, in welcher der Sauglufterzeuger, an welchen sämtliche Bogenbremsen 5a bis 5c angeschlossen sind, weder durch den unbelegten ersten Einlass 31, noch durch den ebenfalls von keinem Bremsmodul belegten zweiten Einlass 32 Falschluft ansaugen kann. In dieser Schaltstellung, welche in Figur 5b illustriert ist, befindet sich das Verschlusssegment 30 in Überdeckung mit dem Auslass 33, um diesen zu verschließen.Figure 4 shows an operation of the
Gemäß der in Figur 4 gezeigten Betriebsweise befindet sich das Mehrwegeventil 22 der einfach bestückten antriebsseitigen Bogenbremse 5a in einer Schaltstellung, in welcher das Verschlusssegment 30 sich vor dem unbelegten zweiten Einlass 32 befindet und es den ersten Einlass 31 und den Auslass 33 freigibt (vgl. auch Figur 5c). Hierzu entgegengesetzt ist eine Schaltstellung (vgl. Figur 5d) des Mehrwegeventils 22 der bedienungsseitigen Bogenbremse 5b, in welcher Schaltstellung vom Ventilkörper 28 ein Saugluftstrom aus dem zweiten Einlass 32 in den Saugluftkanal 21 freigegeben und ein Falschluftstrom aus dem Einlass 31 in den Saugluftkanal 21 unterbunden wird. Damit der Bediener beim Umschalten des Mehrwegeventils 22 dessen Schaltstellungen besser erkennen kann, ist der Ventilkörper 28 mit einer T-förmigen Markierung 34 versehen, welche die Schaltstellungen symbolisch anzeigt.According to the mode of operation shown in FIG. 4, the
Ein Umrüsten des Bogenbremsensystems 3 kann nicht nur zum Zweck eines Betriebsmodus-Wechsels, sondern auch zum Zweck einer von Druckauftrag zu Druckauftrag erforderlichen Anpassung des Bogenbremsensystems 3 an das Format der Druckbogen erforderlich sein. Zur Formatanpassung sind die Bogenbremsen 5a bis 5c entlang einer Führungstraverse 34 verfahrbar, die ein T-förmiges Profil hat (vgl. Figur 3), welches von den Schlitten 6 der Bogenbremsen 5a bis 5c hintergriffen wird. Jede Bogenbremse 5a bis 5c ist mit einem elektromotorischen Stellantrieb 35 ausgestattet, welcher an dem Schlitten 6 befestigt ist und auf dessen Motorwelle ein Ritzel 36 sitzt, das in eine Zahnstange 37 eingreift, die sich zur Führungstraverse 34 parallel erstreckt. Mittels der Stellantriebe 35 sind die Bogenbremsen 5a bis 5c zueinander auf kleineren und größeren Abstand verfahrbar.A retooling of the
In Figur 3 sind ein Bogenanschlag 38 für die Hinterkanten der den Auslagestapel 4 bildenden und auf diesen vom Bogenbremsensystem 3 abzulegenden Druckbogen und ein Bogenleitblech 39 dargestellt, welches in den Figuren 1, 2 und 4 zur Freigabe des Blicks auf die unter dem Bogenleitblech 39 liegenden Bauteile nicht mit dargestellt ist. Das An-und Abkoppeln der Bremsmodule 10, 11 an den und von dem Modulträger 8 erfolgt über zeichnerisch ebenfalls nicht näher dargestellte Steckverbindungen.In Figure 3, a
Bei einer zeichnerisch nicht dargestellten Betriebsart, welche für extrem kleine Bogenformate geeignet ist, können zwei der Bogenbremsen auf Anschlag gegeneinander verfahren werden, wobei die Modulträger dieser beiden Bogenbremsen jeweils nur mit den äußeren Bremsmodulen, jedoch nicht mit den inneren Bremsmodulen bestückt sind. Dieses Bogenbremsen-Duo wird in einer bezüglich der Bogenbreite mittleren Stellung positioniert und die übrige(n) Bogenbremse(n) wird bzw. werden außerhalb der Bogenbreite geparkt.In a graphically not shown operating mode, which is suitable for extremely small sheet sizes, two of the sheet brakes can be moved against each other to stop, the module carrier of these two sheet brakes are each equipped only with the outer brake modules, but not with the inner brake modules. This sheet brake duo is positioned in a middle position relative to the sheet width, and the remaining sheet brake (s) are parked outside the sheet width.
