Description

Die Erfindung betrifft eine Rotationsdruckmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a rotary printing press according to the Preamble of claim 1.

Die US 5 241 905 zeigt eine Druckeinheit, bei der zwei Druckwerke übereinander angeordnet sind und im Gummi-Gummi-Prinzip zusammenarbeiten. Die Zapfen der Zylinder sind in Seitenwänden gelagert. Dabei besitzt eine Seitenwand im Bereich der Übertragungszylinder eine Öffnung. Diese ist durch zwei übereinander schwenkbar an der Seitenwand angeordneten Türen verschließbar bzw. kann durch Schwenken der Türen geöffnet werden. Im Öffnungszustand sind hülsenförmige Gummitücher von den Übertragungszylindern entnehmbar bzw. auf diese schiebbar. Jede Tür nimmt im Schließzustand den Zapfen eines Übertragungszylinders auf. Jeder Zapfen ist hierzu in einer Lagerbüchse gelagert. Diese wiederum wird von einer Bohrung der Tür aufgenommen. Dabei wird die Lagerbuchse auf einem Teilbereich ihres Mantels in zwei halbkreisförmigen Klemmbacken gehaltert. Eine Backe ist lösbar. Um die Tür in die Öffnungsstellung schwenken und dadurch die Öffnung und den Zylinderzapfen freilegen zu können, muß zunächst die Klemmbacke gelöst werden. Hierzu sind ein Arbeitszylinder und mehrgliedriges Getriebe erforderlich, was die Vorrichtung aufwendig gestaltet. Weiterhin ist die Schwenklagerung der Tür selbst aufwendig.US 5 241 905 shows a printing unit in which two printing units are arranged one above the other and in the rubber-rubber principle work together. The pins of the cylinders are in the side walls stored. It has a side wall in the area of Transfer cylinder an opening. This is by two Doors pivoted one above the other on the side wall lockable or can be opened by swiveling the doors. In the open state, tubular rubber blankets are of the Transfer cylinders can be removed or pushed onto them. Every door takes the pin of a transfer cylinder in the closed state. For this purpose, each pin is stored in a bearing bush. This in turn is picked up by a hole in the door. The Bearing bush on a section of its shell in two semicircular jaws held. One jaw can be released. Around swing the door into the open position and thereby the opening and to be able to expose the cylinder journal, the Clamp jaw are released. For this are a working cylinder and multi-unit gear required, which makes the device expensive designed. Furthermore, the pivot bearing of the door itself complex.

Die EP 0 352 599 B1 zeigt eine Druckeinheit, bei der die Öffnung einer Seitenwand von zwei Lagerschilden umschlossen wird. In der Teilungsebene der Lagerschilde sind die Zapfen der Zylinder gelagert. Zum Frei legen der Öffnung werden die Lagerschilde seitlich auseinandergefahren. Für das Öffnen des gesamten Übertragungszylinder- und Plattenzylinderbereiches mittels eines Paares von Lagerschilden wird das Höhen-Breiten-Verhältnis der Lagerschilde sehr groß, so daß die Gefahr des Verkantens besteht. Es müssen entsprechende Vorkehrungen getroffen werden oder mehrere Paare von Lagerschilden verwendet werden. Außerdem sind die erforderlichen Kräfte für die Verstellbewegung und Fixierung sehr hoch.EP 0 352 599 B1 shows a printing unit in which the opening one side wall is enclosed by two end shields. In the The dividing plane of the end shields are the pins of the cylinders stored. To expose the opening, the end shields are on the side spread apart. For opening the whole Transfer cylinder and plate cylinder area by means of of a pair of end shields the height-width ratio of the End shields are very large, so there is a risk of canting. It Appropriate arrangements must be made or more Pairs of end shields can be used. Besides, they are required forces for the adjustment movement and fixation very much high.

Der Erfindung liegt die Aufgabe zugrunde, die Wandöffnung mit einer mit konstruktiv einfachen Mitteln betätigbaren Tür freizulegen.The invention has for its object the wall opening with a Expose door that can be operated using simple design means.

Erfindungsgemäß wird diese Aufgabe bei einer gattungsgemäßen Vorrichtung durch die gegenständlichen Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Das Öffnen der Türflügel ist ohne vorheriges Freilegen der Lagerbuchsen der Zylinder möglich. Somit erübrigen sich kostspielige Vorrichtungen hierfür. Weiterhin sind die Schwenkbewegungen konstruktiv einfach realisierbar, und Probleme der Spielbeseitigung stehen nicht an. Auch ist die Schließstellung einfach fixierbar. Die Verstellkräfte für die Türflügel sind gering und können durch pneumatische Antriebe aufgebracht werden. Mit einem Türflügelpaar können mehrere Zylinderzapfen freigelegt werden. All diese Vorteile schlagen kostensparend zu Buche.According to the invention, this object is achieved with a generic Device through the objective features of the characteristic Part of claim 1 solved. The opening of the door leaves is without previous exposure of the cylinder liners possible. Consequently there is no need for expensive devices for this. Furthermore are the pivoting movements can be implemented in a structurally simple manner, and problems the elimination of the game are not pending. Also the closed position easy to fix. The adjustment forces for the door leaves are low and can be applied by pneumatic drives. Several cylinder pins can be exposed with a pair of door leaves will. All of these advantages save costs.

Fig. 1 zeigt die Teilansicht einer Druckeinheit 1. In deren einen Seitenwand 2, vornehmlich der bedienseitigen, befindet sich eine Öffnung 3, die von zwei Türflügeln 4, 5 verschlossen wird. In den Fig. 1 und 3 ist die Schließstellung der Türflügel 4, 5 gezeichnet. Die Druckeinheit enthält vier Zylinder, und zwar zwei Übertragungszylinder 6, 7, die gegeneinander anstellbar sind und weiterhin mit je einem Formzylinder 8, 9 zusammenarbeiten. Die zur Seitenwand 2 zeigenden Zapfen 10 der Zylinder 6 bis 9 sind in jeweils einer Lagerbüchse 11 bis 14 gelagert, die wiederum im Schließzustand der Türflügel 4, 5 in diesen gelagert sind.Fig. 1 shows the partial view of a printing unit 1. In one Side wall 2, primarily the operator side, is one Opening 3, which is closed by two door leaves 4, 5. In 1 and 3 is the closed position of the door leaves 4, 5th drawn. The printing unit contains four cylinders, two Transfer cylinders 6, 7, which are adjustable against each other and continue to work with a forme cylinder 8, 9. The for Side wall 2 facing pin 10 of the cylinder 6 to 9 are in each bearing bushing 11 to 14, which in turn Closed state of the door leaves 4, 5 are stored in these.

Die Türflügel 4, 5 stellen praktisch die durch Teilung einer Tür 16 entstandenen Teile dar. Die Teilungsebene verläuft mittig zum Außenmantel der Lagerbüchsen 11 bis 14 und parallel zu den Schwenkachsen 17, 18 der Türflügel 4, 5. Bei unterschiedlichem Abstand der Lagerbüchsen 11 bis 14 von den Schwenkachsen 17, 18 ergeben sich somit mehrere Teilungsebenen, und vorteilhaft wird durch senkrecht zu den Schwenkachsen 17, 18 stehende Teilungsebenen eine durchgängige Teilung erzeugt. Die Lage der Schwenkachsen 17, 18 ist so gewählt, daß im Schließzustand der Türflügel 4, 5 die die Lagerbüchsen 11 bis 14 berührenden Konturen der Türflügel 4, 5 nicht durch die Ebene durch die Schwenkachsen 17, 18 hindurchtreten (Fig. 3). Ansonsten würden diese Türbereiche beim Öffnen der Türflügel 4, 5 am Mantel der Lagerbüchse drängen, d.h. die Türflügel ließen sich nicht öffnen. The door leaves 4, 5 practically represent the division of a door 16 created parts. The division level runs in the middle of Outer jacket of the bearing bushes 11 to 14 and parallel to the Pivot axes 17, 18 of the door leaves 4, 5. When different Distance between the bearing bushes 11 to 14 from the pivot axes 17, 18th this results in several levels of division, and is advantageous by dividing planes perpendicular to the pivot axes 17, 18 creates a continuous division. The position of the pivot axes 17, 18 is selected so that in the closed state of the door leaf 4, 5 the Bearing bushes 11 to 14 not touching contours of the door leaves 4, 5 pass through the plane through the pivot axes 17, 18 (Fig. 3). Otherwise these door areas would open when the Push door leaves 4, 5 on the casing of the bearing bush, i.e. the door leaves could not be opened.

Jeder Türflügel 4, 5 besitzt konzentrisch zu seiner Achse 17, 18 zwei Bolzen 19, 20 bzw. 21, 22, die aus den Türflügeln 4, 5 herausragen. Sie sind vorteilhaft in Bohrungen eingesteckt und mit Stiften 31 gesichert. Jeweils zwei benachbarte Bolzen 19, 21 bzw. 20, 22 der Türflügel 4, 5 sind in die Bohrungen einer Konsole 23, 24 eingesteckt. Mitsamt dieser Konsolen 23, 24 sind die Türflügel 4, 5 in die Öffnung 3 der Seitenwand 2 eingesetzt. Die Bohrungen 25, 26 der Konsole 23 sind nicht durchgehend und enthalten im Grund Blattfedern 27, 28, deren Federkraft die Konsole 23 gegen den Rand der Öffnung 3 und die Türflügel 4, 5 mitsamt der Konsole 24 gegen den gegenüberliegenden Rand der Öffnung 3 der Seitenwand drückt und somit die Türflügel 4, 5 spielfrei gegenüber der Seitenwand 2 verspannt. Zwecks Einsetzen der Türflügel 4, 5 in die Seitenwand werden zunächst Schrauben 29 durch Durchgangslöcher der Konsole 23 gesteckt und in die Zapfen 19, 21 eingeschraubt und festgezogen. Dabei wird unter Einfederung der Tellerfedern 27, 28 die Konsole 23 an die Türflügel 4, 5 herangezogen. Dadurch ist das Außenmaß der mit den Konsolen 23, 24 vormontierten Türflügel 4, 5 kleiner als der lichte Abstand der zugehörigen Ränder der Öffnung 3 der Seitenwand 2, und die vormontierten Türflügel 4, 5 können in letztere eingesetzt werden. Beim nunmehrigen Lockern der Schrauben 29 wird die Konsole 23 gegen den Rand der Öffnung 3 gedrückt und werden die Türflügel 4, 5 entlang der Konsolen 23, 24 in der Seitenwand 2 verspannt. Vorteilhaft werden die Konsolen 23, 24 zusätzlich mit Schrauben 30 an der Seitenwand 2 verschraubt. Statt der Tellerfedern können beispielsweise auch Schraubenfedern zur Anwendung kommen. Auch kann auf diese Federn verzichtet werden, wobei dann allerdings die Türflügel 4, 5 kostenaufwendig in die Seitenwand 2 eingepaßt werden müßten. Auch können die Türflügel 4, 5 anderweitig, beispielsweise scharnierartig, wie weiter unten beschrieben, in der Seitenwand 2 gelagert werden.Each door leaf 4, 5 has concentric to its axis 17, 18th two bolts 19, 20 and 21, 22, which come from the door leaves 4, 5 stick out. They are advantageously inserted in bores and with Pins 31 secured. Two adjacent bolts 19, 21 or 20, 22 of the door leaves 4, 5 are in the bores of a bracket 23, 24 plugged in. Together with these brackets 23, 24, the door leaves 4, 5 inserted into the opening 3 of the side wall 2. The holes 25, 26 the console 23 are not continuous and included in the reason Leaf springs 27, 28, the spring force of the bracket 23 against the edge the opening 3 and the door leaves 4, 5 together with the console 24 against presses the opposite edge of the opening 3 of the side wall and thus the door leaves 4, 5 with no play relative to the side wall 2 tense. For the purpose of inserting the door leaves 4, 5 in the side wall are first screws 29 through holes in the console 23rd inserted and screwed into the pin 19, 21 and tightened. The console 23 is thereby deflected by the plate springs 27, 28 pulled to the door panels 4, 5. As a result, the outer dimension is the the brackets 23, 24 pre-assembled door panels 4, 5 smaller than that clear distance between the associated edges of the opening 3 of the side wall 2, and the pre-assembled door panels 4, 5 can be in the latter be used. When loosening the screws 29 now Console 23 pressed against the edge of the opening 3 and the Door leaves 4, 5 along the brackets 23, 24 in the side wall 2 tense. The brackets 23, 24 are also advantageous Screws 30 screwed to the side wall 2. Instead of the disc springs For example, coil springs can also be used. These springs can also be dispensed with, but then the door leaves 4, 5 costly fitted into the side wall 2 should be. The door leaves 4, 5 can also be used otherwise, for example hinge-like, as described below, in the Side wall 2 are stored.

Zum Verschwenken der Türflügel aus der in Fig. 3 gezeichneten Schließstellung in die in Fig. 4 gezeichnete Öffnungsstellung und umgekehrt, wobei die Türflügel 4, 5 um jeweils etwa 90° geschwenkt werden, greift an jedem Türflügel 4, 5 ein Antrieb 32, 33 an. Der Antrieb 33 enthält ein Gelenkviereck, wobei der Türflügel 5 als Abtriebsschwinge fungiert. Die Antriebsschwinge 34 des Gelenkvierecks ist an der Seitenwand 2 gelagert und über eine Koppel 35 gelenkig mit dem Türflügel 5 verbunden, weiterhin steht die Antriebsschwinge 34 mit einem Motor in Antriebsverbindung. Hierfür kommt im Ausführungsbeispiel ein gelenkig an der Seitenwand 2 gelagerter Arbeitszylinder 36 zur Anwendung (Fig. 2). Die Kolbenstange 37 des Arbeitszylinders 36 ist an einen schwenkbar in der Seitenwand 2 gelagerten Hebel 38 angelenkt, der mittels einer Gelenkwelle 39 mit der Antriebsschwinge 34 verbunden ist. In der Schließstellung des Türflügels 5 (Fig. 3) nimmt das Gelenkviereck eine Übertotlagenstellung ein, d.h. die Antriebsschwinge 34 ist geringfügig im Uhrzeigersinn über die Strecklage mit der Koppel 35 hinausgedreht. Diese Übertotlage wird mittels der in die Koppel 35 eingeschraubten, an dem Türflügel 5 anliegenden Anschlagschraube 40 eingestellt. Die Übertotlagenstellung verriegelt den Türflügel 5 zuverlässig gegen unbeabsichtigtes Öffnen, und dies auch bei einem Druckausfall des Arbeitsmediums des Arbeitszylinders 36. Ein gleichartiger und deshalb nicht näher beschriebener Antrieb 32 ist für den Türflügel 4 vorgesehen. Der Antrieb 32 ist aus Vereinfachungsgründen in den Figuren 3 und 4 nicht dargestellt.For pivoting the door leaf from that shown in Fig. 3 Closed position in the open position shown in Fig. 4 and vice versa, the door panels 4, 5 being pivoted about 90 ° each a drive 32, 33 engages on each door leaf 4, 5. Of the Drive 33 contains a four-bar linkage, the door leaf 5 as Output swing arm acts. The drive arm 34 of the Quadrilateral joint is mounted on the side wall 2 and via a coupling 35 articulated with the door leaf 5, continues to stand Drive rocker 34 with a motor in drive connection. Therefor comes in the exemplary embodiment an articulated on the side wall 2 stored working cylinder 36 for use (Fig. 2). The Piston rod 37 of the working cylinder 36 is pivotable in one the side wall 2 mounted lever 38 articulated by means of a Cardan shaft 39 is connected to the drive rocker 34. In the The closed position of the door leaf 5 (Fig. 3) takes the hinge square an overdead position, i.e. the drive rocker 34 is slightly clockwise over the extended position with the coupling 35 turned out. This over-dead position is determined by means of the coupling 35 screwed-in stop screw 40 resting on the door leaf 5 set. The over-dead position locks the door leaf 5 reliable against unintentional opening, even with one Pressure loss of the working medium of the working cylinder 36. On is similar and therefore not described drive 32 provided for the door leaf 4. The drive 32 is off For reasons of simplification, not shown in FIGS. 3 and 4.

Das Freilegen der Öffnung 3 erfolgt, indem die Türflügel 4, 5 in die in Fig. 4 gezeichnete Stellung geschwenkt werden. Hierzu werden die Arbeitszylinder der Antriebe 32, 33 der Türflügel 4, 5 umgesteuert. Für den Türflügel 5 ist dies der Arbeitszylinder 36. Bei dessen Ausfahren wird der Hebel 38 nach unten geschwenkt. Letzterer treibt dabei über die Gelenkwelle 39 die Antriebsschwinge 34 an. Bei deren Schwenken entgegen dem Urzeigersinn zieht sie über die Koppel 35 den Türflügel 5 in die Öffnungsstellung. Analog wird der Türflügel 4 bewegt. Die nunmehr an ihren zur Seitenwand 2 zeigenden Zapfen freigelegten Zylinder 6 bis 9 werden von nicht dargestellten, nicht zur Erfindung gehörenden Klemmmitteln an ihren in der anderen Seitenwand gelagerten Zapfen in der Schwebe gehalten. Nunmehr können Druckformen und Übertragungsformen, gleichgültig ob endlose, d.h. hülsenförmige, oder endliche, von den Übertragungs- und Formzylindern 6 bis 9 abgezogen und durch die Öffnung 3 aus der Druckeinheit entnommen oder umgekehrt in diese eingeführt werden. Eine gerade durch die Öffnung 3 hindurchgeführte hülsenförmige Druckform 87 ist in Figur 4 strichpunktiert angedeutet.The opening 3 is exposed by the door leaves 4, 5 in the in Fig. 4 position pivoted. For this, the Working cylinders of the drives 32, 33 of the door leaves 4, 5 reversed. This is the working cylinder 36 for the door leaf 5 Extend the lever 38 is pivoted downwards. The latter drives the drive rocker 34 via the drive shaft 39. With their Swinging it counterclockwise pulls it over the coupling 35 Door leaf 5 in the open position. The door leaf 4 becomes analogous emotional. The now on their pin to the side wall 2 pointing exposed cylinders 6 to 9 are not shown, not Clamping means belonging to the invention on their in the other Sidewall mounted pegs in suspension.

A sleeve-shaped straight through the opening 3 Printing form 87 is indicated by dash-dotted lines in FIG.

Das beim Antrieb der Türflügel 4, 5 zur Anwendung kommende Gelenkviereck hat den Vorteil, daß dessen von den Türflügeln verkörperte Abtriebsschwinge groß, d.h. mit langem Hebelarm, dimensioniert werden kann. Die Antriebskräfte sind dadurch niedrig, wodurch Pneumatikzylinder eingesetzt werden können. Für den Antrieb des Gelenkvierecks ist auch der Einsatz anderweitiger Antriebsmotoren möglich. Beispielsweise kann die Antriebsschwinge mit einem Schneckengetriebe in Verbindung stehen, daß von einem drehrichtungsumkehrbaren Motor angetrieben wird.The one used to drive the door leaves 4, 5 Articulated rectangle has the advantage that it is from the door leaves embodied output rocker large, i.e. with long lever arm, can be dimensioned. The driving forces are low, whereby pneumatic cylinders can be used. For the drive the quadrilateral joint is also used elsewhere Drive motors possible. For example, the drive rocker connected with a worm gear that from a reversible motor is driven.

Der Antrieb exzentrischer Lagerbüchsen, z.B. der Lagerbüchsen 11, 12 zur Druckan- und -abstellung der Übertragungszylinder 6, 7 ist im Rahmen der Erfindung ebenfalls vorteilhaft realisierbar. Nachfolgend wird ein Betätigungsgetriebe für eine solche Lagerbuchse gezeigt (Fig. 5 bis 7), das sich beim Öffnen und Schließen des Türflügels selbständig von der Lagerbüchse ab- und ankuppelt. In Fig. 5 ist als Ausschnitt von Fig. 2 die in den Türflügeln 4, 5 lagernde Lagerbüchse 12 des Übertragungszylinders 7 dargestellt. Der Zapfen 41 dieses Zylinders 12 ist in einer exzentrisch zum Außenmantel der Lagerbüchse 12 liegenden Bohrung gelagert. Konzentrisch zu ihrem Außenmantel trägt die Lagerbüchse 12 ein geradverzahntes Zahnsegment 42, in das in der Schließstellung des Türflügels 5 ein Stirnrad 43 eingreift. Dieses Stirnrad ist als Segmentrad ausgeführt und auf einem am Türflügel 5 befestigten Lagerbolzen 44 gelagert. Weiterhin ist das Stirnrad 43 gelenkig mit einem Arbeitszylinder 45 verbunden, der schwenkbar am Türflügel 5 befestigt ist. The drive of eccentric bearing bushes, e.g. the bearing bushes 11, 12 for printing on and off the transfer cylinders 6, 7 is in Framework of the invention can also be advantageously implemented. Below an actuating gear for such a bearing bush is shown (Fig. 5 to 7), which occurs when opening and closing the door leaf independently uncoupled and coupled from the bearing bush. 5 is as Excerpt from Fig. 2 which is stored in the door leaves 4, 5 Bearing bush 12 of the transfer cylinder 7 shown. The cone 41 of this cylinder 12 is in an eccentric to the outer jacket Bearing bush 12 lying bore. Concentric to hers The outer sleeve carries the bearing bush 12 a straight toothed tooth segment 42, in which, in the closed position of the door leaf 5, a spur gear 43 intervenes. This spur gear is designed as a segment gear and on a bearing bolt 44 fastened to the door leaf 5. Farther the spur gear 43 is articulated to a working cylinder 45, which is pivotally attached to the door leaf 5.

Je nach Betätigungsrichtung des Arbeitszylinders 45 wird das Stirnrad 43 in die eine oder andere Richtung geschwenkt, das seinerseits die Lagerbüchse 12 für die Druckan- bzw. Druckabstellung in die eine oder andere Richtung dreht. Beim Verschwenken des Türflügels 5 in die Öffnungsstellung (Fig. 7) können die Zähne des mitschwenkenden Stirnrades 43 ungehindert aus der Verzahnung des Zahnsegments 42 austreten. Umgekehrt treten beim Schwenken des Türflügels 5 in die Schließstellung die Zähne des Stirnrades 43 in die Zahnlücken des Zahnsegments 42 ein, wodurch die Antriebsverbindung dieses Zahnradtriebes wieder hergestellt ist. In Fig. 7 ist schematisch auch eine die Öffnung 3 der Seitenwand 2 passierende Gummituchhülse 88 dargestellt. Das in Fig. 5 gezeigte Betätigungsgetriebe ist ebenso wie ein gleichartiges Getriebe für die Lagerbüchse 6 in der Fig. 2 der Übersichtlichkeit halber nicht dargestellt.Depending on the direction of actuation of the working cylinder 45 that will Spur gear 43 pivoted in one direction or the other, that in turn, the bearing bush 12 for printing on or off rotates in one direction or the other. When swiveling the Door leaf 5 in the open position (Fig. 7) can the teeth of the pivoting spur gear 43 unhindered from the teeth of Exit tooth segment 42. Conversely, when swiveling the Door leaf 5 in the closed position, the teeth of the spur gear 43 in the tooth gaps of the tooth segment 42, whereby the Drive connection of this gear drive is restored. In 7 is also a schematic of the opening 3 of the side wall 2 Passing blanket sleeve 88 shown. The one shown in Fig. 5 Actuating gear is just like a similar gear for the bearing bush 6 in FIG. 2 is not for the sake of clarity shown.

Die Türflügel einer Tür können auch auf mehr oder weniger waagerecht liegenden Schwenkachsen angeordnet sein, je nach Lage der Druckwerkszylinder und den Platzverhältnissen. Auch können in einer Tür Zylinder in einer von vier abweichenden Anzahl aufgenommen werden. So zeigt Fig. 8 ausschnittsweise eine Druckeinheit mit zwei Übertragungszylindern 46, 47 und zwei Formzylindern 48, 49, die allesamt etwa waagerecht angeordnet sind. Die Zapfen dieser Zylinder 48 bis 51 werden in Lagerbüchsen 50 bis 53 aufgenommen. Die Lagerbüchsen 52, 53 der Formzylinder 48, 49 lagern direkt in der Seitenwand 54, während die Lagerbüchsen 50, 51 der Übertragungszylinder 46, 47 in Türen 55, 56 aufgenommen werden. Jede Tür 55, 56 ist mittig zum Außenmantel der in ihnen lagernden Lagerbüchsen 50, 51 in zwei Türflügel 57 bis 60 geteilt. Die Teilung verläuft parallel zu den waagerecht liegenden Schwenkachsen 61 bis 64 der Türflügel 57 bis 60. In jeden Türflügel 57 bis 60 ist jeweils eine Achse 65 bis 68 eingesteckt, mittels der jeder Türflügel 57 bis 60 in jeweils einem an der Seitenwand angeschraubten Lagerblock 69 bis 72 gelagert ist. Die Lage der Schwenkachsen 61 bis 64 ist gemäß den oben genannten Kriterien wieder so gewählt, daß sich die Türflügel 57 bis 60 beim Aufschwenken über ihren ganzen Querschnittsbereich von den Lagerbüchsen 50, 51 wegbewegen (Fig. 9). Die Achsen 65 bis 68 sind mit dem jeweiligen Türflügel 57 bis 60 unverdrehbar verbunden und tragen jeweils ebenfalls unverdrehbar ein Schneckenrad 73 bis 76. Mit jedem Schneckenrad 73 bis 76 ist eine Schnecke 77 bis 80 in Eingriff. Die beiden Schnecken 77, 78 bzw. 79, 80 jeweils einer Tür 55, 56 sind auf jeweils einer Schneckenwelle 81, 82 drehfest angebracht. Jede Schneckenwelle 81, 82 wird von einem drehrichtungsumsteuerbaren Motor 83, 84 angetrieben. Die beiden Schnecken 77, 78 bzw. 79, 80 jeweils einer Schneckenwelle 81, 82 haben entgegengerichtete Steigungsrichtungen.The door leaves of a door can also be placed on more or less horizontally lying pivot axes can be arranged depending on the location of the Printing unit cylinder and the space available. Can also in one Door cylinders added in a number different from four will. 8 shows a section of a printing unit with two Transfer cylinders 46, 47 and two forme cylinders 48, 49, the are all arranged approximately horizontally. The cones of these cylinders 48 to 51 are housed in bushings 50 to 53. The Bearing bushes 52, 53 of the forme cylinders 48, 49 are stored directly in the Side wall 54, while the bearing bushes 50, 51 of the Transfer cylinders 46, 47 can be accommodated in doors 55, 56. Each Door 55, 56 is in the middle of the outer jacket of those stored in them Bearing bushes 50, 51 divided into two door leaves 57 to 60. The division runs parallel to the horizontal pivot axes 61 to 64 the door leaf 57 to 60. In each door leaf 57 to 60 is in each case an axis 65 to 68 is inserted, by means of which each door leaf 57 up to 60 in a bearing block screwed to the side wall 69 to 72 is stored. The position of the swivel axes 61 to 64 is selected again according to the above criteria so that the Doors 57 to 60 swing open all over Move the cross-sectional area away from the bearing bushes 50, 51 (FIG. 9). The axes 65 to 68 are with the respective door leaf 57 to 60 non-rotatably connected and also each enter non-rotatably Worm gear 73 to 76. With each worm gear 73 to 76 there is one Snail 77 to 80 engaged. The two snails 77, 78 and 79, 80 each of a door 55, 56 are each on a worm shaft 81, 82 rotatably attached. Each worm shaft 81, 82 is of a reversible motor 83, 84 driven. The two screws 77, 78 and 79, 80 each have a screw shaft 81, 82 have opposite slope directions.

Für das Ausschwenken der Türflügel 57 bis 60 in die in Fig. 9 strichpunktiert angedeutete Öffnungsstellung werden die Motoren 83, 84 angeschaltet. Die dabei in Drehung versetzten Schnecken 77 bis 80 treiben die Schneckenräder 73, 74 bzw. 75, 76 jeweils einer Tür 55, 56 mit gegensätzlichen Drehrichtungen an und bewirken das Aufschwenken der Türflügel 57 bis 60. Nunmehr kann beispielsweise die in Fig. 9 gestrichelt gezeichnete Gummituchhülse 85 vom Übertragungszylinder 47 entnommen und durch die Öffnung 86 der Seitenwand 54 aus der Druckeinheit entnommen oder umgekehrt auf den Übertragungszylinder 47 geschoben werden. Die Türen 55, 56 lassen sich unabhängig voneinander je nach Erfordernis einzeln öffnen. Das Schließen der Öffnung 86, d.h. das Rückschwenken der Türflügel 57 bis 60 erfolgt durch Ansteuern der Motoren 83, 84 mit umgekehrter Drehrichtung. Mit dem Einsatz selbsthemmender Schnecke-Schneckenrad-Getriebe für den Antrieb der Türflügel 57 bis 60 ist deren zuverlässige Lagesicherung in der Öffnungs- und Schließstellung gegeben. Die Lagerung der Türflügel 57 bis 60 in der Seitenwand 54 sowie deren Antrieb kann auch anderweitig, beispielsweise wie in Fig. 1 gezeigt, erfolgen. Der Antrieb zur Verdrehung der Lagerbüchsen 50 und 51 kann analog wie in den Figuren 5 bis 7 ausgeführt werden und ist deshalb nicht dargestellt und beschrieben worden. For swiveling the door leaves 57 to 60 into that in FIG. 9 Open position indicated by dash-dotted lines, the motors 83, 84 switched on. The rotated screws 77 to 80 drive the worm wheels 73, 74 and 75, 76 each of a door 55, 56 with opposite directions of rotation and achieve that Swing door panels 57 to 60 open. Now, for example the blanket sleeve 85 shown in dashed lines in Fig. 9 from Transfer cylinder 47 removed and through the opening 86 of the Sidewall 54 removed from the printing unit or vice versa on the Transfer cylinder 47 are pushed. Leave the doors 55, 56 open independently of each other as required. The Closing the opening 86, i.e. the swinging back of the door leaf 57 to 60 is done by driving motors 83, 84 with the reverse Direction of rotation. With the use of self-locking worm-worm gear for driving the door leaf 57 to 60 is their reliable position securing in the open and closed position given. The storage of the door leaves 57 to 60 in the side wall 54 and their drive can also be otherwise, for example as in 1 shown. The drive to twist the Bearing bushes 50 and 51 can be analogous to those in FIGS. 5 to 7 are executed and is therefore not shown and described been.
