Description

Vorliegende Erfindung betrifft ein 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, wobei in einer Betriebsart an einem der Modulträger zwei der Bremsmodule angekoppelt sind, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a sheet brake system for braking printed sheets, comprising sheet brakes arranged in a row with module carriers arranged such that they can be moved relative to one another for carrying brake modules which are designed to be coupled to and decoupled from the module carriers, with two of the brake modules being attached to one of the module carriers in one operating mode are coupled, according to the preamble of claim 1.

In der DE 102 19 001 A1 ist ein solches Bogenbremsensystem beschrieben, das auf einer Traverse verschiebbar angeordnete Saugstationen umfasst, von denen jede zwei Saugringe trägt, die austauschbar sind.In the DE 102 19 001 A1 such a sheet brake system is described which comprises suction stations which are displaceably arranged on a traverse and each of which carries two suction rings which are interchangeable.

In DE 101 03 235 A1 ist ein Bogenbremsensystem beschrieben. Bei diesem Bogenbremsensystem des Standes der Technik ist an dem jeweiligen Modulträger in einer Betriebsart ein einziges Bremsmodul mit einem Bremsband und in einer anderen Betriebsart ein einziges Stützmodul mit einem Sporenrad angekoppelt. Ungünstig daran ist, dass in der Betriebsart, in welcher die Modulträger jeweils mit einem einzigen Bremsmodul bestückt sind, die Summe der Kontaktflächen der Kontakte zwischen den Bremsbändern und dem zu bremsenden Druckbogen vergleichsweise gering ist. Aufgrund dessen, dass die zur Übertragung der Bremskraft vom Bogenbremsensystem auf den Druckbogen zur Verfügung stehende Gesamtkontaktfläche so gering ist, ist auch die Größe der übertragbaren Bremskraft in zu starkem Maße beschränkt. Bestimmte Betriebsparameter, wie eine hohe Maschinengeschwindigkeit einer die Bogenbremse umfassenden Druckmaschine und eine dementsprechend hohe Bogengeschwindigkeit des am Bogenbremsensystem ankommenden Druckbogens und wie eine hohe Grammatur des Druckbogens, z. B. eines schweren Kartonbogens, erfordern jedoch große Bremskräfte.In DE 101 03 235 A1 describes a sheet brake system. In this sheet brake system of the prior art, a single brake module with a brake band is coupled to the respective module carrier in one mode of operation and a single support module with a tail wheel is coupled in another mode of operation. What is unfavorable about this is that in the operating mode in which the module carriers are each equipped with a single brake module, the sum of the contact surfaces of the contacts between the brake bands and the printed sheet to be braked is comparatively small. Due to the fact that the total contact area available for transmitting the braking force from the sheet braking system to the printed sheet is so small, the size of the braking force that can be transmitted is also limited to an excessive extent. Certain operating parameters, such as a high machine speed of a printing press that includes the sheet brake and a correspondingly high sheet speed of the printed sheet arriving at the sheet brake system, and such as a high grammage of the printed sheet, e.g. B. a heavy sheet of cardboard, but require large braking forces.

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 of creating a sheet braking system which is also suitable for braking heavy printed sheets at high machine speeds.

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, wobei in einer Betriebsart an einem der Modulträger zwei der Bremsmodule angekoppelt sind, ist dadurch gekennzeichnet, dass die Bremsmodule umlaufende Bremselemente umfassen, welche endlose Bremsbänder oder -riemen 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 sheet brakes arranged in a row with module carriers arranged such that they can be moved relative to one another for carrying brake modules which are designed to be coupled to and decoupled from the module carriers, with two of the brake modules being coupled to one of the module carriers in one operating mode , Is characterized in that the braking modules comprise rotating braking elements, which are endless braking bands or belts.

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 area of the contact between the sheet brake system and the printed sheet that is effective when braking the printed sheet. Due to the larger total contact area, a larger braking force can be transmitted from the sheet braking system to the printed sheet. Therefore, the sheet brake system according to the invention for braking high grammage sheets such. B. heavy cardboard sheets, 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 printed sheets such. B. matt-coated sheets of paper and z. B. printed sheets with still wet ink on the sheet brake system facing sheet underside to see. Due to the increased total contact area, the vacuum suction air, by means of which the sheet brake system sucks in the printed sheet, can be reduced. This reduces the risk of markings on the printed sheet caused by the sheet braking system. The doubling of the brake modules is also advantageous in terms of avoiding sagging of the printed sheet between the sheet brakes and in terms of avoiding the formation of waves in the printed sheet, which is particularly important when processing thin paper.

In den Unteransprüchen sind vorteilhafte Weiterbildungen des erfindungsgemäßen Bogenbremsensystems genannt.Advantageous developments of the sheet brake system according to the invention are named in the dependent claims.

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 the module carrier on opposite sides of the latter. In this context it is advantageous if the two braking modules are mirror-symmetrical to one another.

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 subjected to a vacuum. The suction air is extracted from the brake modules via the multi-way valve, by means of which suction air the brake modules suck the printed sheet to the sheet brake. The actuation of the brake modules via the multi-way valve is also advantageous with regard to a simple conversion of the sheet brake system from one mode of operation to the other. For example, the sheet brake system can be easily and quickly converted from a pure recto printing mode to a recto and verso mode of operation if the sheet brake system is part of a perfector printing press. The multi-way valve enables an alternative mode of operation in which only one of the brake modules is coupled to the module carrier. When converting the sheet brake system from the operating mode mentioned at the outset to the alternative operating mode, one of the two brake modules is decoupled from the module carrier and a suction air connection provided on the module carrier for the decoupled brake module is deactivated by means of the multi-way valve, so that no leakage air is sucked in through the latter. With regard to a compact design, it is advantageous if the multi-way valve is integrated into 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 that is 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, in the operating mode mentioned at the outset, two more of the braking modules are coupled to a further one of the module carriers. In this mode of operation, each module carrier of the sheet brake system is preferably equipped with a brake module duo.

Zur Erfindung gehören auch ein Bogenausleger, der mit einem erfindungsgemäß oder einer der Weiterbildungen entsprechend ausgebildeten Bogenbremsensystem ausgerüstet ist, und eine diesen Bogenausleger umfassende Druckmaschine.The invention also includes a sheet delivery device, which is equipped with a sheet brake system designed according to the invention or one of the developments, and a printing press that includes this sheet delivery device.

Vorteilhafte Weiterbildungen der Erfindung ergeben sich auch aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels und der dazugehörigen Zeichnung.Advantageous further developments of the invention also result from the following description of a preferred exemplary embodiment and the associated drawing.

The module carrier 8 carries a braking module 10 on the left with respect to the conveying or running direction 9 of the printed sheet and a braking module 11 on the right. The two braking modules 10, 11 are mirror-symmetrical to one another. The respective brake module 10, 11 includes a brake band 12, which runs around deflection rollers 13, 14 and a drive roller 15. The drive roller 15 is non-rotatably connected to a friction wheel 16 or formed in one piece with the latter. The friction wheel 16 rests against a common drive roller 17, which extends over all sheet brakes 5a to 5c (cf. figure 1 ) and is rotatably mounted in a frame 18.

Figur 1 zeigt, dass die Antriebswalze 17 mit einem elektrischen Antriebsmotor 19 verbunden ist und dass die Reibräder 16 aller linker und rechter Bremsmodule sämtlicher Bogenbremsen an der Antriebswalze 17 anliegen und über letztere durch den Antriebsmotor 19 rotativ angetrieben werden, welcher somit die Bremsbänder 12 antreibt. Jede Bogenbremse 5a bis 5c umfasst eine Feder 20, welche bestrebt ist, den Modulträger 8 um das Gelenk 7 zu schwenken, um die beiden Reibräder 16 der jeweiligen Bogenbremse gegen die Antriebswalze 17 zu drängen. figure 1 shows that the drive roller 17 is connected to an electric drive motor 19 and that the friction wheels 16 of all left and right brake modules of all sheet brakes are in contact with the drive roller 17 and are driven in rotation via the latter by the drive motor 19, which thus drives the brake belts 12. Each sheet brake 5a to 5c comprises a spring 20 which strives to pivot the module carrier 8 about the joint 7 in order to urge the two friction wheels 16 of the respective sheet brake against the drive roller 17.

Figuren 2 und 3 zeigen weiterhin, dass in den Modulträger 8 ein Saugluftkanal 21 eingebracht ist, an dessen den Bremsmodulen 10, 11 zu gelegenes Ende ein Mehrwegeventil 22 angeschlossen ist. Das andere Ende des Saugluftkanals 21 bildet einen Anschluss 23 für einen zeichnerisch nicht dargestellten Sauglufterzeuger, der über einen Schlauch an den Anschluss 23 angeschlossen ist. Jedes Bremsmodul 10, 11 hat eine Saugkammer 24 zum durch eine Perforation 25 des Bremsbands 12 hindurch erfolgenden Ansaugen des abzubremsenden Druckbogens an das Bremsband 12. Die Saugkammern 24 haben jeweils eine Mündung 26 in der dem Modulträger 8 zugewandten Seitenfläche des jeweiligen Bremsmoduls 10, 11. Das Mehrwegeventil 22 umfasst einen um eine vertikale Achse 27 drehbaren Ventilkörper 28. Der Ventilkörper 28 wird mittels eines Steckschlüssels gedreht, der auf ein vierkantiges Steckprofil 29 des Ventilkörpers 28 gesteckt wird. Der drehbar in dem Modulträger 8 gelagerte Ventilkörper 28 hat im Wesentlichen die Form einer Büchse - also eines mit Decke und Boden verschlossenen Hohlzylinders - in deren Umfangswandung ein Fenster eingebracht ist, das sich über drei Quadranten erstreckt. In dem vierten Quadranten bildet der verbliebene Teil der Umfangswandung ein Verschlusssegment 30. figures 2 and 3 also show that a suction air duct 21 is introduced into the module carrier 8, at the end of which a multi-way valve 22 is connected towards the brake modules 10, 11. The other end of the suction air channel 21 forms a connection 23 for a suction air generator, not shown in the drawing, which is connected to the connection 23 via a hose. Each brake module 10, 11 has a suction chamber 24 for sucking the printed sheet to be braked onto the brake band 12 through a perforation 25 in the brake band 12. The suction chambers 24 each have an opening 26 in the side surface of the respective brake module 10, 11 facing the module carrier 8. The multi-way valve 22 includes a valve body 28 that can be rotated about a vertical axis 27 . The rotatably mounted valve body 28 in the module carrier 8 essentially has the shape of a can—that is, a hollow cylinder closed with a top and bottom—in whose peripheral wall a window is introduced that extends over three quadrants. In the fourth quadrant, the remaining part of the peripheral wall forms a closure segment 30.

In den Figuren 5a bis 5d sind verschiedene Drehstellungen des Ventilkörpers 28 dargestellt. Der Ventilkörper 28 lässt sich durch nacheinander erfolgende 90°-Drehungen in seine mit den vier Schaltstellungen des Mehrwegeventils 22 korrespondierenden Drehstellungen bringen. Der Ventilkörper 28 wird in der jeweiligen der Drehstellungen durch Reibschluss mit der Bohrung, in die der Ventilkörper 28 eingesetzt ist, oder durch eine Rastung, z. B. mit einer gefederten Rastkugel, gehalten. Die in Figur 5a dargestellte Drehstellung ist für den in Figur 2 dargestellten Rüstzustand der Bogenbremse vorgesehen. In diesem Rüstzustand sind beide Bremsmodule 10, 11 an den Modulträger 8 angedockt. Demgemäß befindet sich das Mehrwegeventil 22 in einer Schaltstellung, in welcher die Saugluft aus der Saugkammer 24 des rechten Bremsmoduls 11 über einen ersten Einlass 31 des Mehrwegeventils 22 und die Saugluft aus der Saugkammer 24 des linken Bremsmoduls 10 über einen zweiten Einlass 32 des Mehrwegeventils 22 in dieses hineinströmen kann und aus einem Auslass 33 des Mehrwegeventils 22 aus letzterem heraus und in den Saugluftkanal 21 strömen kann. In besagter Schaltstellung gibt das Verschlusssegment 30 sowohl die beiden Einlässe 31, 32 als auch den Auslass 33 frei, wie dies in Figur 5a dargestellt ist. Die beiden Einlässe 31, 32 werden durch eine horizontale Bohrung gebildet, welche die vertikale Bohrung, in die der Ventilkörper 28 eingesetzt ist, schneidet. Beide Bohrungen schneiden den Saugluftkanal 21. Die Mündung 26 der Saugkammer 24 des rechten Bremsmoduls 11 befindet sich mit dem ersten Einlass 31 in luftleitender Überdeckung und die Mündung der Saugkammer 24 des linken Bremsmoduls 10 befindet sich mit dem zweiten Einlass 32 in luftleitender Überdeckung.In the Figures 5a to 5d different rotational positions of the valve body 28 are shown. The valve body 28 can be brought into its rotational positions corresponding to the four switching positions of the multi-way valve 22 by successively occurring 90° turns. The valve body 28 is in each of the rotational positions by frictional engagement with the bore into which the valve body 28 is inserted, or by a detent, z. B. held with a spring-loaded detent ball. In the Figure 5a The rotary position shown is for the in figure 2 shown set-up state of the sheet brake provided. In this set-up state, both brake modules 10, 11 are docked to the module carrier 8. accordingly is the multi-way valve 22 in a switching position in which the suction air from the suction chamber 24 of the right brake module 11 via a first inlet 31 of the multi-way valve 22 and the suction air from the suction chamber 24 of the left brake module 10 via a second inlet 32 of the multi-way valve 22 in this can flow in and out of an outlet 33 of the multi-way valve 22 from the latter and can flow into the suction air channel 21 . In said switching position, the closure segment 30 releases both the inlets 31, 32 and the outlet 33, as shown in Figure 5a is shown. The two inlets 31, 32 are formed by a horizontal bore which intersects the vertical bore into which the valve body 28 is inserted. Both bores intersect the suction air channel 21. The mouth 26 of the suction chamber 24 of the right brake module 11 is in air-conducting overlap with the first inlet 31 and the mouth of the suction chamber 24 of the left brake module 10 is in air-conducting overlap with the second inlet 32.

Gemäß Figur 1 sind alle Bogenbremsen 5a bis 5c in dem Rüstzustand, der mit Bezug auf die Figuren 2 und 5a erläutert worden ist. Hierbei sind die Modulträger 8 jeweils mit den Bremsmodulen 10, 11 doppelt bestückt. Diese besonders für den reinen SchöndruckBetriebsmodus der Druckmaschine 1 geeignete Betriebsweise des Bogenbremsensystems 3 wird auch als Tandembetrieb bezeichnet.According to figure 1 are all sheet brakes 5a to 5c in the setup state with respect to the figures 2 and 5a has been explained. Here, the module carrier 8 are each equipped with the brake modules 10, 11 twice. This mode of operation of the sheet brake system 3, which is particularly suitable for the straight printing operating mode of the printing press 1, is also referred to as tandem operation.

Figur 4 zeigt eine Betriebsweise des Bogenbremsensystems 3, welche besonders für den Schön- und Wiederdruck-Betriebsmodus der Druckmaschine 1 geeignet ist. Hierbei sind die beiden Bremsmodule 10, 11 der mittleren Bogenbremse 5c von deren Modulträger 8 abgekoppelt und ist an den Modulträgern 8 der beiden äußeren Bogenbremsen 5a, 5b jeweils nur noch das äußere Bremsmodul angedockt. 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 operating mode of the sheet brake system 3 which is particularly suitable for the perfecting and perfecting operating mode of the printing press 1. The two brake modules 10, 11 of the central sheet brake 5c are decoupled from their module carrier 8 and only the outer brake module is still docked to the module carriers 8 of the two outer sheet brakes 5a, 5b. Accordingly, the multi-way valve 22 of the unequipped central sheet brake 5c is turned into a switching position in which the suction air generator, to which all sheet brakes 5a to 5c are connected, leaks air neither through the unoccupied first inlet 31 nor through the second inlet 32, which is also not occupied by a brake module can suck. In this switch position, which in Figure 5b As illustrated, the closure segment 30 is in registry with the outlet 33 to close the same.

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 figure 4 The operating mode shown is that the multi-way valve 22 of the single-equipped drive-side sheet brake 5a is in a switching position in which the closure segment 30 is in front of the unoccupied second inlet 32 and it releases the first inlet 31 and the outlet 33 (cf. also Figure 5c ). Opposite to this is a switching position (cf. Figure 5d ) of the multi-way valve 22 of the operator-side sheet brake 5b, in which switching position the valve body 28 releases a suction air flow from the second inlet 32 into the suction air channel 21 and a secondary air flow from the inlet 31 into the suction air channel 21 is prevented. The valve body 28 is provided with a T-shaped marking 34, which symbolically indicates the switching positions, so that the operator can better recognize the switching positions when switching over the multi-way valve 22.

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 conversion of the sheet brake system 3 may be required not only for the purpose of changing the operating mode, but also for the purpose of adapting the sheet brake system 3 to the format of the printed sheet, as required from print job to print job. To adapt the format, the sheet brakes 5a to 5c can be moved along a guide traverse 34, which has a T-shaped profile (cf. figure 3 ), which is gripped behind by the carriage 6 of the sheet brakes 5a to 5c. Each sheet brake 5a to 5c is equipped with an electromotive actuator 35 which is attached to the carriage 6 and on the motor shaft of which there is a pinion 36 which engages in a toothed rack 37 which extends parallel to the guide traverse 34. By means of the actuators 35, the sheet brakes 5a to 5c can be moved to a smaller or larger distance from one another.

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 are a sheet stop 38 for the trailing edges of the delivery pile 4 forming and on this sheet to be stored by the sheet brake system 3 printed sheets and a sheet guide plate 39 shown, which in the figures 1 , 2 and 4 is not shown to release the view of the underlying sheet guide plate 39 components. The coupling and decoupling of the brake modules 10, 11 to and from the module carrier 8 takes place via plug-in connections, which are also not shown in detail in the drawing.

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 an operating mode not shown in the drawing, which is suitable for extremely small sheet formats, two of the sheet brakes can be moved against one another until they stop, with the module carriers of these two sheet brakes only being fitted with the outer braking modules but not with the inner braking modules. This sheet brake duo is positioned in a middle position with respect to the sheet width and the remaining sheet brake(s) is/are parked outside the sheet width.
