Description

Die Erfindung betrifft eine Bogenauslagevorrichtung an Druckmaschinen mit pneumatischen Bremsvorrichtungen am Kettenausleger, die als rotierende, mit Saugluft beaufschlagte Bremswalzen auf einer unterhalb des Kettenförderers quer zur Bogenförderrichtung vor dem Auslagestapel verlaufenden Trägerwelle zum Abbremsen und Straffen der einlaufenden Bogen angeordnet sind.The invention relates to a sheet delivery device on printing presses with pneumatic braking devices on the chain delivery, which are arranged as rotating brake rollers acted upon by suction air on a carrier shaft running below the chain conveyor transversely to the sheet conveying direction in front of the delivery stack for braking and tightening the incoming sheets.

Bei Bogenauslagevorrichtungen mit Bremsvorrichtungen dieser Bauart wird die Bremswirkung auf das Ende des auslaufenden und abzulegenden Bogens durch eine geringere Umfangsgeschwindigkeit der Saugbremswalzen gegenüber der höheren, der Bogengeschwindigkeit entsprechenden Umlaufgeschwindigkeit der Kettengreifer erzielt. Durch die vorhandene Differenzgeschwindigkeit zwischen Saugbremswalzen und Bogen wird dieser außerdem gestrafft. Sobald die Bogenvorderkante von den Kettengreifern freigegeben wird, üben die Saugbremswalzen eine Bremswirkung auf das hintere Ende des Bogens aus und verlangsamen denselben bis zum Verlassen dessen Hinterkante von der Saugbremswalze derart, daß der gestraffte Bogen mit annähernder Umfangsgeschwindigkeit der Saugbremswalzen eben auf den Auslagestapel aufgelegt wird.In sheet delivery devices with braking devices of this type, the braking effect on the end of the outgoing and to be deposited sheet is achieved by a lower peripheral speed of the suction brake rollers compared to the higher rotating speed of the chain grippers, which corresponds to the sheet speed. The difference in speed between the suction brake rollers and the bow also tightens them. As soon as the front edge of the sheet is released by the chain grippers, the suction brake rollers exert a braking effect on the rear end of the sheet and slow it down until it leaves the rear edge of the suction brake roller in such a way that the tightened sheet is placed on the delivery stack at approximately the circumferential speed of the suction brake rollers.

Insbesondere bei Schön- und Widerdruckarbeiten kann durch entsprechend hohe Differenzgeschwindigkeit zwischen Saugbremswalzen und Bogen die frisch bedruckte Bogenunterseite an den Saugbremswalzen abschmieren, weshalb sich die Notwendigkeit ergibt, dieselben nur in druckfreien Bogenbereichen anzustellen.Particularly in the case of perfecting and reverse printing work, the freshly printed underside of the sheet can be smeared on the suction brake rollers by a correspondingly high differential speed between the suction brake rollers and the sheet, which is why there is a need to employ the same only in pressure-free sheet areas.

Es sind nun Bremsvorrichtungen bekannt, die den oben geschilderten Gegebenheiten insofern Rechnung tragen, daß ihre Saugbremswalzen auf druckfreie Bogenstellen seitlich verstellbar sind. In der Praxis ergibt sich jedoch die Schwierigkeit, daß insbesondere bei Schön-und Widerdruckarbeiten oft nur äußerst schmale druckfreie Bereiche innerhalb des Druckbildes vorhanden sind, so daß breite Saugwalzen, d.h. solche mit einer breiten Bogenauflagefläche nicht mehr zum Einsatz kommen können.Braking devices are now known which take into account the circumstances described above to the extent that their suction brake rollers are laterally adjustable on pressure-free arc points. In practice, however, there is the difficulty that, particularly in the case of perfecting and reverse printing work, there are often only extremely narrow, pressure-free areas within the printed image, so that wide suction rolls, i.e. those with a wide sheet support surface can no longer be used.

Die DE - OS 26 27 812 zeigt eine solche Bremsvorrichtung, bei der die Saugbremswalzen auf druckfreie Bogenstellen seitlich verstellbar sind. Da jedoch die Bogenauflageflächen der Saugbremswalzen relativ breit sind, besteht die Gefahr, wenn der Abstand zwischen zwei entsprechend breiten druckfreien Bereichen innerhalb des Druckbildes sehr groß ist, daß die Bogen, insbesondere bei leichteren Papierqualitäten, zum Durchhängen neigen. Um diesem Mangel vorzubeugen, hat man nun zwischen den Saugrädern auf Tragscheiben angeordnete Spornrädchen vorgesehen, die den Bogen zusätzlich unterstützen.DE-OS 26 27 812 shows such a braking device in which the suction brake rollers can be laterally adjusted to pressure-free arc points. However, since the sheet contact surfaces of the suction brake rollers are relatively wide, there is a danger if the distance between two correspondingly wide, pressure-free areas within the printed image is very large, that the sheets tend to sag, particularly with lighter paper qualities. In order to prevent this shortcoming, spur wheels have been provided between the suction wheels on support disks, which additionally support the bow.

Dieser Vorrichtung haftet der Nachteil an, daß unter Umständen eine gleichmäßige Verzögerung des Bogens über seine gesamte Breite nicht gewährleistet ist. Ferner trägt diese Vorrichtung nicht der Möglichkeit Rechnung, daß ausschließlich schmale druckfreie Bereiche innerhalb des Druckbildes vorhanden sind. In solchen Fällen ist auch sie ungeeignet und kann nicht zum Einsatz kommen.This device has the disadvantage that under certain circumstances a uniform deceleration of the sheet over its entire width is not guaranteed. Furthermore, this device does not take into account the possibility that only narrow, pressure-free areas are present within the printed image. In such cases, it is also unsuitable and cannot be used.

Eine weitere Möglichkeit, dem eingangs genannten Mißstand abzuhelfen besteht darin, die Bremsvorrichtungen mit Saugbremswalzen ausaustatten, die eine schmale Bogenauflagefläche mit einer Breite von z.B. 2 bis 3 mm aufweisen, und mit denen die obengenannten Probleme behoben werden können. Derartigen Saugbremswalzen mit schmaler Bogenauflagefläche sind nun aber wieder hinsichtlich ihrer Saug- bzw. Bremskraft Grenzen gesetzt, die nur mit einem unverhältnismäßig großen Aufwand zu überwinden sind, da deren Saugwirkung bei schweren Papieren, z.B. über 130 g/m2, und bei maximaler Geschwindigkeit nicht ausreicht um die Bogen in gewünschtem Maße genügend zu verzögern.Another possibility to remedy the situation mentioned at the outset is to equip the braking devices with suction brake rollers, which have a narrow sheet support surface with a width of, for example, 2 to 3 mm, and with which the problems mentioned above can be remedied. Such suction brake rollers with a narrow sheet support surface are now again limited in terms of their suction or braking force, which can only be overcome with a disproportionate amount of effort, since their suction effect on heavy papers, for example over 130 g / m 2 , and not at maximum speed sufficient to delay the bends sufficiently to the desired extent.

Es besteht also die Möglichkeit, bei der Montage der Maschine entweder Saugbremswalzen mit breiter Saug- bzw. Bogenauflagefläche in den Bremsvorrichtungen anzuordnen und somit eine gute Bremswirkung zu erzielen oder aber solche mit schmaler Saug- bzw. Bogenauflagefläche vorzusehen und dadurch bei Verarbeitung von stärkeren Papieren oder Karton zwangsweise eine zu geringe Bremswirkung in Kauf zu nehmen. Eine Verstärkung der Bremskraft infolge Erhöhung des Vakuums ist aus fertigungstechnischen Gründen und vom Aufwand, sowohl hinsichtlich der Mittel als auch der Kosten her gesehen, nur in begrenztem Umfang möglich.So there is the possibility, when assembling the machine, either to arrange suction brake rollers with a wide suction or sheet support surface in the braking devices and thus achieve a good braking effect, or to provide those with a narrow suction or sheet support surface and thereby when processing thicker papers or Carton forced to accept an insufficient braking effect. An increase in the braking force due to an increase in the vacuum is only possible to a limited extent for manufacturing reasons and in terms of expenditure, both in terms of means and costs.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Bogenauslagevorrichtung mit pneumatischen Bremsvorrichtungen zu schaffen, die eine Anpassung deren Bremskraft an die jeweils zu verarbeitende Papiersorte zum Erzielen einer optimalen Bremswirkung auf die abzulegenden Bogen in kurzer Zeit und mit einfachen Mitteln ermöglicht.Based on this prior art, the invention has for its object to provide a sheet delivery device with pneumatic braking devices that allows an adaptation of their braking force to the type of paper to be processed to achieve an optimal braking effect on the sheets to be deposited in a short time and with simple means.

Diese Aufgabe wird erfindungsgemäß mit einer Bogenauslagevorrichtung der eingangs genannten Art dadurch gelöst, daß die Bremsvorrichtungen austauschbar gegen solche mit einer andersartig ausgebildeten Bogentragfläche sind. Mit dieser Anordnung kann einer Veränderung der druckfreien Zonen im Druckbild sowie der Wahl einer anderen Papiersorte unverzüglich Rechnung getragen werden, durch die Möglichkeit eines äußerst schnellen Wechsels der Bremsvorrichtungen mit geringem Arbeitsaufwand.This object is achieved according to the invention with a sheet delivery device of the type mentioned in the introduction in that the braking devices are interchangeable with those with a differently shaped sheet supporting surface. With this arrangement, a change in the pressure-free zones in the printed image and the choice of a different paper type can be taken into account immediately, by the possibility of an extremely rapid change of the braking devices with little effort.

In vorteilhafter Ausgestaltung der Erfindung ist die Trägerwelle einteilig ausgebildet, auf der die Bremsvorrichtungen abnehm- und aufsteckbar angeordnet sind. Durch diesen problemlosen Aufbau ist eine leichte Handhabung der Bremsvorrichtungen gewährleistet, da nur wenige einfache Handgriffe zu deren Austausch erforderlich sind.In an advantageous embodiment of the invention, the carrier shaft is formed in one piece, on which the braking devices are arranged so as to be removable and attachable. This problem-free design ensures easy handling of the braking devices, since only a few simple steps are required to replace them.

Eine Weiterbildung des Erfindungsgedankens, die sich insbesondere zur Anwendung fast aller gebräuchlicher und bekannter Saugwalzen eignet, dabei durch geringen Aufwand hinsichtlich der konstruktiven Mittel äußerst kostengünstig herzustellen ist und außerdem kürzeste Tauschzeiten garantiert, ist die Trägerwelle mehrteilig und trennbar ausgebildet, auf der die Bremsvorrichtungen abziehbar angeordnet sind.A further development of the concept of the invention, which is particularly suitable for the use of almost all customary and known suction rolls, is extremely inexpensive to manufacture due to the low outlay in terms of the design means and also guarantees the shortest replacement times, the carrier shaft is designed in several parts and can be separated, on which the braking devices can be removed are.

Zwecks weiterer Vereinfachung und Zeitersparnis des Bremswalzen- austausches sind die Bremsvorrichtungen einteilig ausgeführt als Bremswalzen mit eingearbeiteten Saugkammern und integrierter Saugluftzuführung, wobei der Antrieb der Bremswalzen über separate Antriebsräder erfolgt.To further simplify and save time when replacing the brake rollers, the brake devices are designed in one piece as brake rollers with built-in suction chambers and integrated suction air supply, the brake rollers being driven by separate drive wheels.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind in der nachfolgenden Beschreibung und in den Unteransprüchen 4 bis 7 und 10 bis 15 enthalten.Further advantageous refinements of the inventive concept are contained in the following description and in subclaims 4 to 7 and 10 to 15.

Wie in Figur 1 dargestellt, ist bei einer Grundausführung der Erfindung vor dem Auslagestapel 1 eines Bogenauslegers in den Seitenwänden 2 und 3-eines Saugwalzenwagens eine einteilige Trägerwelle 4 befestigt. Auf der einteiligen Trägerwelle 4 sind in beliebig wählbaren Abständen einzelne abnehm- und aufsteckbare einteilige Bremsvorrichtungen 5 verschiebbar angeordnet, die mittels Klemmschrauben 6 feststellbar sind.As shown in FIG. 1, in a basic embodiment of the invention, a one-piece carrier shaft 4 is fastened in front of the delivery stack 1 of a sheet boom in the side walls 2 and 3 of a suction roller carriage. On the one-piece carrier shaft 4, individual removable and attachable one-piece braking devices 5 are slidably arranged at arbitrary intervals, which can be locked by means of clamping screws 6.

Versetzt zur einteiligen Trägerwelle 4, unterhalb und in Bogenlaufrichtung gesehen vor derselben, ist in den Seitenwänden 2 und 3 eine Antriebswelle 7 gelagert, die von einem an der Außenseite der Seitenwand 3 angeflansch ten Motor 8 angetrieben wird. Auf der Antriebswelle 7 sind, in den Zwischenräumen der einteiligen Bremsvorrichtungen 5 ensprechenden Abständen, diesen gegenüberstehende Antriebsräder 9 angeordnet. Die Antriebsräder 9 sind nur in Umfangsrichtung fixiert und werden in axialer Richtung durch die einteiligen Bremsvorrichtungen 5 geführt.Offset to the one-piece carrier shaft 4, below and seen in the sheet running direction in front of the same, a drive shaft 7 is mounted in the side walls 2 and 3, which is driven by a motor 8 flange-mounted on the outside of the side wall 3. On the drive shaft 7, in the spaces between the one-piece braking devices 5 corresponding distances, these opposing drive wheels 9 are arranged. The drive wheels 9 are fixed only in the circumferential direction and are guided in the axial direction by the one-piece braking devices 5.

Gemäß den Figuren 2 und 3 besteht eine einteilige Bremsvorrichtung 5 jeweils aus einem Halter 12, dessen hinteres Ende in etwa als halbkreisförmige Lagerschale 13 ausgebildet ist, welche auf die einteilige Trägerwelle 4 aufsteckbar ist. Zum Arretieren des Halters 12 dient die zuvor bereits erwähnte Klemmschraube 6, die endseitig in die Lagerschale 13 eingelassen ist. Am vorderen Ende des Halters 12 ist eine Saugluftkammerhülse 14 befestigt, auf der mittels Kugellagern 15 eine Bremswalze 16 gelagert ist. In die Bremswalze 16 sind bis auf die Mantelfläche der Saugluftkammerhülse 14 durchgehende Saugkammern 17 eingearbeitet, so daß die Bremswalze 16 die Form eines Stegrades aufweist. Außerdem ist die Bremswalze 16 an ihren beiden Seiten mit zwei Antriebsrillen 18 versehen.According to FIGS. 2 and 3, a one-piece braking device 5 consists of a holder 12, the rear end of which is formed approximately as a semicircular bearing shell 13, which can be plugged onto the one-piece carrier shaft 4. The previously mentioned clamping screw 6, which is inserted at the end into the bearing shell 13, is used to lock the holder 12. At the front end of the holder 12, a suction air chamber sleeve 14 is fastened, on which a brake roller 16 is mounted by means of ball bearings 15. Continuous suction chambers 17 are incorporated into the brake roller 16 except for the outer surface of the suction air chamber sleeve 14, so that the brake roller 16 has the shape of a step. In addition, the brake roller 16 is provided on both sides with two drive grooves 18.

An dem der Oberseite des Halters 12 und somit dem abzubremsenden Bogen 10 zugewandten Umfangsteil der Saugluftkammerhülse 14 ist deckungsgleich zu der auf dieser gelagerten Bremswalze 16 eine innere Lufteinfaßöffnung 19 eingelassen. Ebenso ist das freie Ende der Saugluftkammerhülse 14 am Umfang mit einer äußeren Lufteinlaßöffnung 20 versehen, die sich mit dem Saugluftkanal einer Saugluftzufuhrung 21 deckt, welcher an einer Lufteinlaßhülse 22 angebracht ist. Die Lufteinlaßhülse 22 ist auf das freie Ende der Saugluftkammerhülse 14 aufgesteckt und mittels eines Gewindestiftes 23 feststellbar.On the circumferential part of the suction air chamber sleeve 14 facing the upper side of the holder 12 and thus the sheet 10 to be braked, an inner air intake opening 19 is congruent with the brake roller 16 mounted on it. Likewise, the free end of the suction air chamber sleeve 14 is provided on the circumference with an outer air inlet opening 20 which coincides with the suction air duct of a suction air supply 21, which is attached to an air inlet sleeve 22. The air inlet sleeve 22 is plugged onto the free end of the suction air chamber sleeve 14 and can be fixed by means of a threaded pin 23.

Auf der Antriebswelle 7 sind die Antriebsräder 9 in einer den Haltern 12 entsprechenden Anzahl in einer Längsnut 24 verschiebbar angeordnet und in dieser mittels Mitnehmerschrauben 25 in Umfangsrichtung fixiert.On the drive shaft 7, the drive wheels 9, in a number corresponding to the holders 12, are arranged displaceably in a longitudinal groove 24 and fixed in the circumferential direction by means of driving screws 25.

Die Antriebsräder 9 sind beidseitig mit Antriebsrillen 26 versehen, die den Antriebsrillen 18 der Bremswalzen 16 fluchtend gegenüberstehen. In den Antriebsrillen 26 laufen Antriebsriemen 27 um, die die Bremswalzen 16 in den Antriebsrillen 18 umspannen. Als Antriebsriemen 27 kommen dabei vorzugsweise solche mit kreisförmigem Querschnitt zum Einsatz. Es liegt jedoch im Rahmen der Erfindung, andere Riemenarten, z.B. mit flach-oder trapezförmigen Profilen zu verwenden. Natürlich kann der Antrieb der Bremswalzen 16 auch über Zahnriemen und Zahnriemenscheiben erfolgen.The drive wheels 9 are provided on both sides with drive grooves 26 that drive grooves 18 of the brake rollers 16 face flush. Drive belts 27 circulate in the drive grooves 26 and span the brake rollers 16 in the drive grooves 18. As drive belts 27 preferably those with a circular cross section are used. However, it is within the scope of the invention to use other types of belts, for example with flat or trapezoidal profiles. Of course, the brake rollers 16 can also be driven via toothed belts and toothed belt pulleys.

Wie in den Figuren 2 und 3 dargestellt, sind die Antriebsräder 9 einseitig mit einer Führungsnut 28 ausgestattet, die von einem seitlichen Stützbund 29 begrenzt wird. Die auf der einteiligen Trägerwelle 4 festgeklemmten Halter 12 liegen mit einer in diese eingearbeiteten halbreisförmigen Stützschulter 30 in der Führungsnut 28 auf und sichern dadurch die Antriebsräder 9 gegen eine ungewollte axiale Verschiebung.As shown in Figures 2 and 3, the drive wheels 9 are equipped on one side with a guide groove 28 which is delimited by a lateral support collar 29. The clamped on the one-piece carrier shaft 4 holder 12 lie with a semi-circular support shoulder 30 incorporated into it in the guide groove 28 and thereby secure the drive wheels 9 against unwanted axial displacement.

Anstelle der Anwendung von Antriebsriemen 27 können die Antriebsräder 9 mit einer Verzahnung versehen werden, deren umlaufende Zähne in die Saugkammern 17 der Bremswalzen 16 eingreifen und dieselben dadurch antreiben.Instead of using drive belts 27, the drive wheels 9 can be provided with teeth, the circumferential teeth of which engage in the suction chambers 17 of the brake rollers 16 and thereby drive the same.

Die Wirkungsweise sowie die Handhabung zum Austausch der einteiligen Bremsvorrichtungen gegen solche mit andersartig ausgebildeter Bogentragfläche geht folgendermaßen vor sich:

  • Die Antriebsräder 9 der vom Motor 8 angetriebenen Antriebswelle 7 übertragen ihre Rotationsbewegung entweder mittels der Antriebsriemen 27 oder der Verzahnung auf die Bremswalzen 16. Dabei wird die Saugluft des nicht dargestellten Vakuumerzeugers über den Saugluftkanal der Saugluftzuführungen 21 durch die äußere Lufteinlaßöffnung 20 in die Saugluftkammerhülse 14 eingeleitet und gelangt von dort über die innere Lufteinlaßöffnung 19 immer nur in die vertikal zuoberst liegenden Saugkammern 17 der Bremswalzen 16, auf denen der Bogen 10 aufliegt, so daß keine falsche Luft angesaugt werden kann (Fig. 2).
The mode of operation and the handling for replacing the one-piece braking devices with those with a differently shaped arch supporting surface proceed as follows:
  • The drive wheels 9 of the drive shaft 7 driven by the motor 8 transmit their rotational movement either by means of the drive belts 27 or the toothing to the brake rollers 16 and passes from there via the inner air inlet opening 19 only into the vertically uppermost suction chambers 17 of the brake rollers 16, on which the sheet 10 rests, so that no incorrect air can be drawn in (FIG. 2).

Zum Austausch der einteiligen Bremsvorrichtungen 5 werden nun die Antriebsriemen 27 von Hand aus den Antriebsrillen 18 und 26 der Antriebsräder 9 und der Bremswalzen 16 ausgehoben und abgestreift. Sodann werden die Klemmschrauben 6 der Halter 12 gelöst, so daß dieselben nach oben von der einteiligen Trägerwelle 4 abgenommen und gegen. einteilige Bremsvorrichtungen 5 mit Bremswalzen 16 schmälerer oder breiterer Bauart ausgetauscht werden können. Diese werden dann einfach wieder von oben auf die einteilige Trägerwelle 4 aufgesteckt, wozu als Führung und Auflager für die Halter 12 die Führungsnut 28 dient. Dadurch stehen die Antriebsräder 9 den Bremswalzen 16 automatisch in einer Fluchtlinie gegenüber. Die Feststellung der neu eingesetzten Bremsvorrichtungen 5 erfolgt mittels der Klemmschrauben 6. Abschließend werden die Antriebsriemen 27 wieder in die Antriebsrillen 18 und 26 eingelegt, so daß diese die Antriebsräder 9 und die Bremswalzen 16 umspannen.To replace the one-piece braking devices 5, the drive belts 27 are now lifted and stripped by hand from the drive grooves 18 and 26 of the drive wheels 9 and the brake rollers 16. Then the clamping screws 6 of the holder 12 are loosened, so that they are removed upwards from the one-piece carrier shaft 4 and counter. one-piece brake devices 5 can be replaced with brake rollers 16 narrower or wider design. These are then simply pushed back onto the one-piece carrier shaft 4 from above, for which purpose the guide groove 28 serves as a guide and support for the holder 12. As a result, the drive wheels 9 automatically face the brake rollers 16 in an alignment line. The newly installed brake devices 5 are determined by means of the clamping screws 6. Finally, the drive belts 27 are reinserted in the drive grooves 18 and 26 so that they span the drive wheels 9 and the brake rollers 16.

Zum seitlichen Verschieben der einteiligen Bremsvorrichtungen 5 auf druckfreie Streifen des Druckbildes müssen lediglich die Klemmschrauben 6 der Halter 12 gelöst und nach deren seitlichen Positionierung mitsamt den nur in Umfangsrichtung fixierten Antriebsrädern 9 wieder angezogen werden.To move the one-piece braking devices 5 laterally onto pressure-free strips of the printed image, only the clamping screws 6 of the holders 12 have to be loosened and after their lateral positioning together with the drive wheels 9 which are only fixed in the circumferential direction, they have to be tightened again.

In einer ersten Ausführungsform der Erfindung gemäß Figur 4 ist die Trägerwelle 31 zweiteilig ausgebildet und fungiert dabei gleichzeitig als Antriebswelle. Sie ist in ein langes Trägerwellenteil 32 und ein kurzes Trägerwellenteil 33 untergliedert, wobei der Antrieb über den an der Seitenwand 2 angeflanschten Motor 8 auf das in dieser gelagerte lange Trägerwellenteil 32 erfolgt. Das lange Trägerwellenteil 32 muß an seinem der Seitenwand 2 der Antriebsseite der Maschine zugewandten Ende zumindest um die Breite einer Bremswalze 34 auf der zweiteiligen Trägerwelle 31 in wählbaren Abständen angeordneter zweiteiliger Bremsvorrichtungen 35 kürzer sein als die lichte Weite zwischen den beiden Seitenwänden 2 und 3. Das kurze Trägerwellenteil 33 zur Überbrückung vom langen Trägerwellenteil 32 zur Seitenwand 3 ist als Steckwelle ausgebildet, welche mittels eines Handgriffes 36 aus der Seitenwand 3 herausziehbar ist. Das kurze Trägerwellenteil 33 weist an ihrem Ende einen Wellenzapfen 37 auf, der in eine endseitig in das lange Trägerwellenteil 32 eingelassene Bohrung 38 einschiebbar ist. Die beiden Trägerwellenteile 32 und 33 können dabei mittels einer Feststellschraube 39 oder stattdessen mittels anderer bekannter Arretierelemente, wie z.B. einer Kugelraste, miteinander arretiert werden.In a first embodiment of the invention according to FIG. 4, the carrier shaft 31 is formed in two parts and at the same time functions as a drive shaft. It is subdivided into a long carrier shaft part 32 and a short carrier shaft part 33, the drive being effected via the motor 8 flanged onto the side wall 2 onto the long carrier shaft part 32 mounted therein. The long support shaft part 32 must be shorter at its end facing the side wall 2 of the drive side of the machine by at least the width of a brake roller 34 on the two-part support shaft 31 of selectively spaced two-part brake devices 35 than the clear width between the two side walls 2 and 3 short carrier shaft part 33 for bridging from the long carrier shaft part 32 to the side wall 3 is designed as a stub shaft which can be pulled out of the side wall 3 by means of a handle 36. The short carrier shaft part 33 has at its end a shaft journal 37 which can be inserted into a bore 38 inserted into the end of the long carrier shaft part 32. The two carrier shaft parts 32 and 33 can thereby by means of a locking screw 39 or instead by means of other known locking elements, such as e.g. a ball catch, can be locked together.

Gemäß den Figuren 5 bis 8 besteht eine zweiteilige Bremsvorrichtung 35 jeweils aus einer der bereits oben genannten Bremswalzen 34 sowie aus einem auf die Bremswalze 34 aufsteckbaren separaten Saugkörper 41, der - je nach Breite der gewünschten Bogentragfläche - mit einer oder mehreren Saugkammern 42 ausgestattet ist, welche über eine Saugluftzuführung 43 mit dem nicht dargestellten und näher beschriebenen Vakuumerzeuger verbunden sind. Der Saugkörper 41 ist an einer Lagerschelle 44 fixiert, welche auf eine parallel und horizontal in einer Ebene zu der zweiteiligen Trägerwelle 31, jedoch in Laufrichtung des Bogens 10 gesehen, vor derselben in den Seitenwänden 2 und 3 befestigten Traverse 45 von oben aufgesteckt ist. Die Feststellung der Lagerschelle 44 auf der Traverse 45 erfolgt mittels einer unterhalb dieser in die Lagerschelle 44 eingelegten Lasche 46, die mittig mit einer Feststellschraube 47 versehen ist.According to FIGS. 5 to 8, a two-part brake device 35 each consists of one of the brake rollers 34 already mentioned above and a separate suction body 41 which can be plugged onto the brake roller 34 and which - depending on the width of the desired sheet support surface - is equipped with one or more suction chambers 42, which are connected via a suction air supply 43 to the vacuum generator, not shown and described in more detail. The absorbent body 41 is fixed to a bearing clamp 44, which is attached from above to a crossbar 45 fastened in parallel and horizontally in one plane to the two-part carrier shaft 31, but seen in the running direction of the sheet 10, in front of the same in the side walls 2 and 3. The bearing clamp 44 is fixed on the crossmember 45 by means of a tab 46 inserted below the bearing clamp 44, which is provided in the center with a locking screw 47.

Die in einer Längsnut 48 der zweiteiligen Trägerwelle 31 verschiebbar angeordneten Bremswalzen 34 werden mittels Mitnehmerschrauben 49 in Umfangsrichtung arretiert. Am vorderen Ende der auf die Bremswalzen 34 aufgesteckten Saugkörper 41 ist in einer lagerförmigen Vertiefung 50 eine drehbare Umlenkrolle 51 eingelegt. Die Bremswalzen 34 sowie die Umlenkrollen 51 werden jeweils von zumindest einem Bremsband 52 umspannt, das in seitlich in die Bremswalzen 34 eingelassenen Rillen 53 geführt wird (Figur 5).The in a longitudinal groove 48 of the two-part Carrier shaft 31 slidably arranged brake rollers 34 are locked in the circumferential direction by means of driving screws 49. At the front end of the suction body 41 attached to the brake rollers 34, a rotatable deflection roller 51 is inserted in a bearing-shaped recess 50. The brake rollers 34 and the deflection rollers 51 are each spanned by at least one brake band 52, which is guided in grooves 53 embedded in the side of the brake rollers 34 (FIG. 5).

Je nachdem, ob die Bremswalzen 34 der zweiteiligen Bremsvorrichtungen 35 mit schmaler oder breiter Bogentragfläche ausgestattet sind, unterscheidet sich deren Aufbau. Die Bremswalzen 34 mit schmaler Bogentragfläche 54 der Figuren 4 bis 6 weisen einen durchgehenden Mittelsteg 55 und beiderseitige Nabenansätze 56 auf. Der Mittelsteg 55 der Bremswalzen 34 mit schmaler Bogentragfläche 54 ist mit einer halbkreisförmigen Rille 53 versehen, in der das Bremsband 52 eingebettet ist, mittels dem der zu transportierende Bogen 10 abgebremst wird. Gemäß Figur 4 kommt bei dieser schmalen Ausführung der Bremswalzen 34 ein Saugkörper 41 zum Einsatz, der durch eine mittige Ausnehmung in zwei getrennte Saugkammern 42 unterteilt ist und auf den Mittelsteg 55 der Bremswalzen 34 aufgesteckt wird, so daß die beiden Saugkammern 42 beiderseits des Mittelstegs 55 auf den Nabenansätzen 56 der Bremswalzen 34 zu liegen kommen.Depending on whether the brake rollers 34 of the two-part brake devices 35 are equipped with a narrow or wide sheet support surface, their structure differs. The brake rollers 34 with a narrow curved support surface 54 in FIGS. 4 to 6 have a continuous central web 55 and hub extensions 56 on both sides. The central web 55 of the brake rollers 34 with a narrow sheet support surface 54 is provided with a semicircular groove 53 in which the brake band 52 is embedded, by means of which the sheet 10 to be transported is braked. According to FIG. 4, a suction body 41 is used in this narrow design of the brake rollers 34, which is divided into two separate suction chambers 42 by a central recess and is plugged onto the central web 55 of the brake rollers 34, so that the two suction chambers 42 on both sides of the central web 55 come to rest on the hub lugs 56 of the brake rollers 34.

Bei den in den Figuren 7 und 8 dargestellten Bremswalzen 34 mit breiter Bogentragfläche 58 ist mittig eine breite Aussparung 59 vorgesehen, die von den beiden Seitenwänden 60 begrenzt wird, auf denen je ein Bremsband 52 in Rillen 53 umläuft. In die breite Aussparung 59 der Bremswalzen 34 mit breiter Bogentragfläche 58 wird jeweils ein Saugkörper 41 mit einer einzelnen Saugkammer 42 eingesteckt.In the brake rollers 34 shown in FIGS. 7 and 8 with a wide arch support surface 58, a wide recess 59 is provided in the center, which is delimited by the two side walls 60, on each of which a brake band 52 rotates in grooves 53. In each case a suction body 41 with a single suction chamber 42 is inserted into the wide cutout 59 of the brake rollers 34 with a wide arc bearing surface 58.

Der Austausch der zuvor beschriebenen ersten Ausführungsform der zweiteiligen Bremsvorrichtungen 35 geht folgendermaßen vor sich:

  • Zum Auswechseln der Bremswalzen 34 mit schmaler Bogentragfläche 54 gegen solche mit breiter Bogentragfläche 58 muß zuerst das einen jeden Mittelsteg und die Umlenkrolle 51 umspannende Bremsband 52 von Hand von der Umlenkrolle 51 abgehoben werden. Danach wird mittels der Feststellschrauben 47 die Arretierung der Saugkörper 41 mit ihrer Saugluftzuführung 43 soweit aufgehoben, daß die Laschen 46 den Lagerschellen 44 entnommen werden können. Die Saugkörper 41 können nun von oben von der Traverse 45 abgenommen werden.
The replacement of the previously described first embodiment of the two-part brake devices 35 proceeds as follows:
  • To replace the brake rollers 34 with a narrow arch support surface 54 for those with a wide arch support surface 58, the brake band 52 spanning each central web and the deflection roller 51 must first be lifted from the deflection roller 51 by hand. Then the locking of the suction body 41 with its suction air supply 43 is released by the locking screws 47 to such an extent that the tabs 46 can be removed from the bearing clamps 44. The suction bodies 41 can now be removed from the cross member 45 from above.

Danach wird eine Trennung der zweiteiligen Trägerwelle 31 bewirkt, indem die Arretierung der beiden Trägerwellenteile 32 und 33 durch die Feststellschraube 39 gelöst wird und die Steckwelle 33 mittels des Handgriffes 36 aus dem verbleibenden langen Trägerwellenteil 32 sowie aus der Seitenwand 3 herausgezogen werden kann.Thereafter, the two-part carrier shaft 31 is separated by releasing the locking of the two carrier shaft parts 32 and 33 by the locking screw 39 and the stub shaft 33 can be pulled out of the remaining long carrier shaft part 32 and from the side wall 3 by means of the handle 36.

Die nur in Umfangsrichtung in der Längsnut 48 gesicherten Bremswalzen 34 können sodann mitsamt ihren Bremsbändern 52 durch die zur Seitenwand 3 freistehende Öffnung von dem langen Trägerwellenteil 32 abgezogen und stattdessen Bremswalzen 34 mit breiter Bogentragfläche 58 aufgezogen werden. Die neu eingesetzten Bremswalzen 34 werden nun auf druckfreie Bereiche des Druckbildes seitlich verschoben und mittels der Feststellschrauben 47 festgestellt. Danach wird die Steckweite 33 wieder in die Seitenwand 3 eingeschoben, so daß der Wellenzapfen 37 in der Bohrung 38 des langen Trägerwellenteiles 32 zu liegen kommt. Nachdem die Steckwelle 33 am langen Trägerwellenteil 32 wieder arretiert ist, werden die einzelnen Saugkörper 41 mit ihrer jeweiligen Saugluftzuführung 43 von oben auf die Traverse ' 45 aufgesteckt und in die breiten Aussparungen 59 der Bremswalzen 34 eingelegt. Die beiden Bremsbänder 52 der Bremswalzen 34 mit breiter Bogentragfläche 58 werden - nun wieder von Hand auf die Umlenkrollen 51 aufgelegt. Die derart montierten zweiteiligen Bremsvorrichtungen 35 sind nun zum Einsatz betriebsbereit.The brake rollers 34, which are secured only in the circumferential direction in the longitudinal groove 48, can then be pulled off from the long support shaft part 32 together with their brake bands 52 through the free-standing opening to the side wall 3, and instead brake rollers 34 with a wide arc bearing surface 58 can be pulled up. The newly used brake rollers 34 are now shifted laterally onto pressure-free areas of the printed image and are fixed by means of the locking screws 47. Then the plug-in width 33 is pushed back into the side wall 3, so that the shaft journal 37 comes to rest in the bore 38 of the long support shaft part 32. After the stub shaft 33 is locked again on the long carrier shaft part 32, the individual suction bodies 41 with their respective suction air supply 43 are plugged onto the cross member 45 from above and inserted into the wide recesses 59 of the brake rollers 34. The two brake bands 52 of the brake rollers 34 with a wide curved bearing surface 58 are now placed on the deflection rollers 51 again by hand. The two-part brake devices 35 assembled in this way are now ready for use.

Es versteht sich von selbst, daß das Ablaufschema der Reihenfolge der einzelnen Arbeitsgänge zum Austausch der zweiteiligen Bremsvorrichtungen 35 nach Belieben veränderbar ist, d.h., daß z.B. zuerst die Saugkörper 41 mit ihrer .Saugluftzuführung 4 und danach erst die Bremswalzen 34 ausgetauscht werden können oder daß dieser Vorgang auch in umgekehrter Reihenfolge stattfinden kann.It goes without saying that the flowchart of the sequence of the individual operations for exchanging the two-part brake devices 35 can be changed as desired, i.e. that e.g. first the suction body 41 with its suction air supply 4 and only then the brake rollers 34 can be exchanged or that this process can also take place in the reverse order.

Bei einem in Figur 6 dargestellten zweiten Ausführungsbeispiel der zweiteiligen Bremsvorrichtungen 35 mit teilbarer Trägerwelle 31 wird der auslaufende Bogen 10 durch Bremswalzen 34 mit schmaler Bogentragfläche 54 verzögert. Die Trägerwelle 31 ist zweiteilig ausgeführt, wobei zwischen einem in der Seitenwand 2 gelagerten Antriebszapfen 64 und einem in der Seitenwand 3 gelagerten langen Trägerwellenteil 65 eine Kupplung 66 eingeschaltet ist. Zum Austausch der zweiteiligen Bremsvorrichtungen 35 muß das lange Trägerwellenteil 65 vom Antriebszapfen 64 entkuppelt und dann zumindest um die Breite einer Bremswalze 34 mittels des Handgriffes 36 aus der Seitenwand 3 herausgezogen werden. Der Austausch der zweiteiligen Bremsvorrichtungen 35 selbst erfolgt wie zuvor beschrieben.In a second exemplary embodiment of the two-part brake devices 35 with a separable carrier shaft 31 shown in FIG. 6, the outgoing sheet 10 is decelerated by brake rollers 34 with a narrow sheet support surface 54. The carrier shaft 31 is designed in two parts, a clutch 66 being engaged between a drive pin 64 mounted in the side wall 2 and a long carrier shaft part 65 mounted in the side wall 3. To replace the two-part brake devices 35, the long carrier shaft part 65 must be uncoupled from the drive pin 64 and then pulled out of the side wall 3 by means of the handle 36 at least by the width of a brake roller 34. The two-part brake devices 35 themselves are exchanged as previously described.

Gemäß Figur 7 ist bei einem dritten Ausführungsbeispiel der zweiteiligen Bremsvorrichtungen die Trägerwelle 63 dreiteilig ausgebildet. Sie weist ein mittleres langes Trägerwellenteif 67 auf, das mittels zweier Kupplungen 66 mit dem in der Seitenwand 2 gelagerten kurzen Antriebzapfen 64 und einem in' der Seitenwand 3 angeordneten kurzen Lagerzsapfen 68 verbunden ist. Zum Austausch der zweiteiligen Bremsvorrichtungen 35 müssen zuerst die Saugkörper 41 von den Bremswalzen 34 getrennt werden. Dies erfolgt durch Ausheben der Bremsbänder' 52 aus den Umlenkrollen 51 der Saugkörper 41. Nun kann das mittlere lange Trägerwellentell 67 aus den beiden Kupplungen 66 ausgekuppelt und als ganze Einheit mitsamt den Bremswalzen 34 aus der Maschine herausgenommen werden, so daß der eigentliche Austausch der Bremswalzen 34 außerhalb der Maschine erfolgen kann. Der Austausch der Saugkörper 41 auf der Traverse 45 wird getrennt davon, wie bereits oben beschrieben, vorgenommen.According to FIG. 7, the carrier shaft 63 is constructed in three parts in a third exemplary embodiment of the two-part braking devices. It has a medium-long carrier shaft part 67, which is connected by means of two couplings 66 to the short drive journal 64 mounted in the side wall 2 and to a short bearing journal 68 arranged in the side wall 3. To the end Exchange of the two-part brake devices 35, the suction body 41 must first be separated from the brake rollers 34. This is done by lifting the brake bands' 52 out of the deflection rollers 51 of the suction bodies 41. Now the medium long carrier shaft 67 can be disengaged from the two clutches 66 and removed as a whole unit together with the brake rollers 34 from the machine, so that the actual replacement of the brake rollers 34 can be done outside the machine. The exchange of the suction body 41 on the cross member 45 is carried out separately, as already described above.

Wie in Figur 8 dargestellt, ist bei einem vierten Ausführungsbeispiel der zweiteiligen Bremsvorrichtungen 35 die Trägerwelle 63 ebenfalls dreiteilig ausgebildet. Am freien Ende des in der Seitenwand 2 gelagerten Antriebszapfens 64 ist ein Gelenk 69 befestigt, an dem das mittlere lange Trägerwellenteil 70 angelenkt ist. In der gegenüberliegenden Seitenwand 3 ist ein kurzer Kupplungszapfen 71 gelagert, mit dem das andere Ende des mittleren Trägerwellenteils 70 durch die Kupplung 66 verbunden ist. Der kurze Kupptungszapfen 71 ist mittels des Handgriffes 36 verdreh- bzw. herausziehbar.As shown in FIG. 8, in a fourth exemplary embodiment of the two-part braking devices 35, the carrier shaft 63 is likewise made in three parts. At the free end of the drive pin 64 mounted in the side wall 2, a joint 69 is fastened, to which the middle long support shaft part 70 is articulated. A short coupling pin 71 is mounted in the opposite side wall 3 and is connected to the other end of the central carrier shaft part 70 by the coupling 66. The short coupling pin 71 can be rotated or pulled out by means of the handle 36.

Zum Austausch der zweiteiligen Bremsvorrichtungen 35 werden die Saugkörper 41 genau wie beim dritten Ausführungsbeispiel von den Bremswalzen 34 getrennt. Danach wird das mittlere lange Trägerwellenteil 70 durch Verdrehen bzw. Herausziehen des kurzen Kupplungszapfens 71 an der Seitenwand 3 ent--kuppelt und kann dann anschließend zum Ausstausch der Bremswälzen 34, je nach verwendetem Gelenk 69, in beliebige Lagen verschwenkt werden.To replace the two-part brake devices 35, the suction bodies 41 are separated from the brake rollers 34 exactly as in the third exemplary embodiment. The middle long support shaft part 70 is then uncoupled by rotating or pulling out the short coupling pin 71 on the side wall 3 and can then be pivoted into any positions to replace the brake rollers 34, depending on the joint 69 used.

Die Erfindung ist natürlich keinesfalls auf die in den Figuren 1 bis 8 dargestellten und in der Beschreibung niedergelegten Ausführungsformen beschränkt, sondern kann innerhalb ihres Rahmens die verschiedensten Abänderungen hinsichtlich ihrer baulichen Einzelheiten erfahren. So liegt es durchaus im Rahmen der Erfindung, die Trägerwelle 31, 63 mittig oder an beliebig anderer Stelle trennbar bzw. auskuppelbar zu machen oder andere Saugbremswalzen bekannter Bauart auf derselben anzuordnen.The invention is of course in no way limited to the embodiments shown in FIGS. 1 to 8 and laid down in the description, but can experience a wide variety of changes with regard to its structural details within its scope. Thus, it is entirely within the scope of the invention to make the carrier shaft 31, 63 separable or disengageable in the center or at any other location, or to arrange other suction brake rollers of the known type on the same.
