Description

Die Erfindung betrifft eine Wechselstation für Sleeves von DruckmaschinenThe invention relates to a changing station for sleeves of printing presses

Zur Abwicklung von Druckaufträgen ist es häufig notwendig, die Druckmotive der Druckwalzen einer Druckmaschine zu wechseln. Um einen Auftragswechsel möglichst schnell und einfach durchführen zu können, werden häufig nur die so genannten Drucksleeves, die die Druckmotive tragen, ausgewechselt.For the processing of print jobs, it is often necessary to change the print motifs of the printing rollers of a printing press. In order to be able to carry out a job change as quickly and easily as possible, often only the so-called printing sleeves, which carry the print motifs, are exchanged.

Die US 3,877,370 zeigt eine Offsetdruckmaschine mit mehreren Druckeinheiten. Die Druckeinheiten bestehen aus einer Basis und einen austauschbaren Kopf 19. Die Basis 18 umfasst eine Anpresswalze. Der Kopf umfasst einen Druckzylinder, einen Gummituchzylinder, ein Farbwerk und ein Feuchtwerk. Der komplette Kopf einer jeden Druckeinheit kann mithilfe eines Krans ausgetauscht werden. Der Kran ist vertikal und mithilfe einer Linearführung auch horizontal entlang der Druckeinheiten verfahrbarThe US 3,877,370 shows an offset printing machine with several printing units. The printing units consist of a base and an exchangeable head 19. The base 18 comprises a pressure roller. The head comprises a printing cylinder, a blanket cylinder, an inking unit and a dampening unit. The complete head of each pressure unit can be replaced with a crane. The crane is vertical and can also be moved horizontally along the pressure units using a linear guide

Die noch unveröffentlichte Patentanmeldung DE 101 12 522 zeigt eine Aufnahmevorrichtung mit einer Mehrzahl von Tragedornen zur Aufnahme von Drucksleeves. Diese Aufnahmevorrichtung wird in die Nähe eines Druckwerks gebracht. Zu diesem Zweck besitzt sie Räder, mit denen sie auf dem Boden der Maschinenhalle fahrbar ist. Um die Aufnahmevorrichtung auch in einen geeigneten Abstand zu höhergelegenen Druckwerken zu bringen, kann die Aufnahmevorrichtung an einer an der Druckmaschine vorgesehenen Hebebühne angebracht werden. Die entnommenen Sleeves werden manuell von dem Bedienpersonal von der Druck- und oder Rasterwalze abgezogen, zu der Aufnahmevorrichtung herübergehoben und auf einen Tragedorn der Aufnahmevorrichtung aufgeschoben. Die Aufnahmevorrichtung trägt in der Regel auch die Sleeves für den neuen Druckauftrag, die ebenfalls manuell bewegt und auf die Druck- und oder Rasterwalze aufgezogen werden. Bei den beschriebenen Arbeiten steht das Bedienpersonal auf der erwähntenThe still unpublished patent application DE 101 12 522 shows a receiving device with a plurality of support pins for receiving Drucksleeves. This recording device is brought into the vicinity of a printing unit. For this purpose, it has wheels, with which it is mobile on the floor of the machine hall. In order to bring the recording device in a suitable distance to higher-lying printing units, the recording device can be attached to a provided on the printing machine lift. The removed sleeves are manually withdrawn by the operator of the printing and or anilox roller, lifted to the receiving device and pushed onto a support mandrel of the receiving device. The recording device usually also carries the sleeves for the new print job, which are also moved manually and mounted on the printing and or anilox roller. In the described work, the operator is on the mentioned

Hebebühne und hebt die zu wechselnden Sleeves von der Druckmaschine zur Aufnahmevorrichtung und umgekehrt.Lift and lifts the sleeves to be changed from the printing press to the receiving device and vice versa.

Diese ohnehin durch das Gewicht der Sleeves und die Notwendigkeit des Aufziehens des zu wechselnden Dorns auf den Druckzylinder oder den Tragedorn schwere Arbeit wird oft zusätzlich erschwert, wenn die Position des zu wechselnden Sleeves in der Aufnahmevorrichtung gegenüber der Achse der Druck- oder Rasterwalze stark verschoben ist.This in any case by the weight of the sleeves and the need to wind the mandrel to be changed on the printing cylinder or the carrying mandrel heavy work is often further complicated if the position of the sleeve to be changed in the receiving device relative to the axis of the printing or anilox roller is strongly shifted ,

Die Aufgabe der vorliegenden Erfindung besteht daher darin, die Arbeit zu erleichtern.The object of the present invention is therefore to facilitate the work.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Hierbei kann ein erfindungsgemäßes Magazin auch aus lediglich einer Aufnahmevorrichtung bestehen. Eine Aufnahmevorrichtung kann von einem Tragedorn aber auch von einer regalähnlichen oder schubladenförmigen Ablage oder anderen zur Lagerung von Sleeves geeigneten Bauelementen gebildet werden.This object is solved by the characterizing features of claim 1. In this case, a magazine according to the invention can also consist of only one receiving device. A receiving device can be formed by a carrying mandrel but also by a shelf-like or drawer-shaped tray or other components suitable for storing sleeves.

Die horizontale Verfahrbarkeit des Magazins kann vorteilhafterweise von einer oder mehreren kranähnlichen Vorrichtungen vorgenommen werden, wobei eine Anlenkung des Magazins an mehreren Kranseilen die Möglichkeit der Verkippung des Magazins eröffnet. Von dieser Möglichkeit kann Gebrauch gemacht werden, wenn mehrere Aufnahmevorrichtungen des Magazins gleichzeitig zu mehreren Walzen ausgerichtet werden sollen. Wenn die Achsen dieser Walzen nicht in einer horizontalen Ebene liegen, kann eine Verkippungsmöglichkeit des Magazins sehr nützlich sein. Zur Realisierung dieser Möglichkeit kommen natürlich auch andere Vorrichtungen als die Bereitstellung mehrerer Kräne in Frage.The horizontal mobility of the magazine can be advantageously carried out by one or more crane-like devices, with an articulation of the magazine on several crane ropes opens up the possibility of tilting of the magazine. This possibility can be used if several recording devices of the magazine are to be aligned simultaneously to several rolls. If the axes of these rolls are not in a horizontal plane, it may be very useful to tilt the magazine. To realize this possibility, of course, other devices than the provision of multiple cranes come into question.

Die horizontale Verfahrbarkeit kann vorteilhafterweise mit Hilfe einer Linearführung sichergestellt werden. Bei einer Kombination der vorgenannten Vorrichtungen zur Realisierung der Verfahrbarkeit empfiehlt sich das in der gegenständlichen Beschreibung vorgestellte Kran-Schiene-System.The horizontal mobility can be advantageously ensured by means of a linear guide. In a combination of the aforementioned devices for the realization of the mobility is recommended in the present description presented crane rail system.

Bei Magazinen mit mehreren Aufnahmevorrichtungen sind zusätzliche Mittel zum Ändern der Position zumindest einer Aufnahmevorrichtung innerhalb des Magazins nützlich. Mit deren Hilfe kann eine "Feineinstellung" der Position der Aufnahmevorrichtung zu einer Walzenachse vorgenommen werden, ohne dass das gesamte Magazin bewegt werden muss. In den Ansprüchen und der gegenständlichen Beschreibung werden unterschiedliche Realisierungsmöglichkeiten für diese Feineinstellung offenbart. Zunächst wird ein auf einer Scheibe basierendes revolverartiges Magazin, welches die Aufnahmevorrichtungen um einen Drehpunkt rotiert, beansprucht. Ein ähnliches Prinzip liegt einem endlosen Band oder einer Kette zugrunde, welche in dem Magazin umläuft und hierbei die Aufnahmevorrichtungen mit sich führt.In multi-tray magazines, additional means for changing the position of at least one picking device within the magazine are useful. With their help, a "fine adjustment" of the position of the Receiving device are made to a roll axis without the entire magazine must be moved. In the claims and the subject description different implementation options for this fine adjustment are disclosed. First, a disk-based revolver-type magazine that rotates the pickup devices about a pivot point is claimed. A similar principle is based on an endless belt or chain, which rotates in the magazine and thereby carries the recording devices with it.

Auch Vorrichtungen, welche auf einem schacht- oder regalartigen Ordnungssystem beruhen und in ihrer Funktion an einen traditionellen Zigarettenautomat erinnern können, lassen sich vorteilhaft in dem geschilderten Zusammenhang einsetzen.Even devices which are based on a shaft or shelf-like classification system and can remind in their function of a traditional cigarette vending machine, can be used advantageously in the described context.

Bei allen Mitteln zum Ändern der Position der zumindest einenFor all means for changing the position of the at least one

Aufnahmevorrichtung im Magazin ist es von großem Vorteil, wenn zumindest zwei Aufnahmevorrichtungen hintereinander in die selbe Position gebracht werden können. Wenn diese Möglichkeit besteht, kann beim Austausch der Sleeves zunächst eine leere Aufnahmevorrichtung in eine günstige Position zu einer Walzenachse gebracht werden. Diese Aufnahmevorrichtung kann dann mit dem bei dem vorangegangenen Druckvorgang gebrauchten Sleeve beladen und in eine andere Position gebracht werden. Diejenige Aufnahmevorrichtung, die den "neuen" in die Druckmaschine einzusetzenden Sleeve trägt, nimmt dann die günstige Position zur Walzenachse ein.Recording device in the magazine, it is of great advantage if at least two recording devices can be brought one behind the other in the same position. If this possibility exists, when replacing the sleeves initially an empty pick-up device can be brought into a favorable position to a roll axis. This recording device can then be loaded with the used in the previous printing sleeve and placed in a different position. The receiving device that carries the "new" to be used in the printing sleeve, then takes the favorable position to the roll axis.

Ein weiteres vorteilhaftes Merkmal liegt in dem Abstand, welchen die Aufnahmevorrichtungen voneinander haben. Wenn beispielsweise sowohl der Rasterwalzensleeve als auch der Druckwalzensleeve eines Farbwerkes zeitsparend ausgetauscht werden sollen, dann sollte der Abstand der den beiden Walzen zugeordneten Aufnahmevorrichtung dem Abstand der beiden Walzen zueinander entsprechen, damit die zum Austausch beider Walzen günstige Position "gleichzeitig" erreicht werden kann. Ein weiterer Justiervorgang des Magazins oder der Aufnahmevorrichtungen in demAnother advantageous feature lies in the distance which the receiving devices have from each other. For example, if both the Rasterwalzensleeve and the Druckwalzensleeve an inking unit to be replaced time-saving, then the distance of the two rollers associated recording device should correspond to the distance of the two rollers to each other, so that the favorable position for the exchange of both rolls "simultaneously" can be achieved. Another adjustment of the magazine or the recording devices in the

Magazin wird dann überflüssig.Magazine is then superfluous.

Wie eingangs erwähnt wird die Austauscharbeit, welche das Bedienpersonal zu leisten hat, durch jede Verbesserung der Ausrichtung der Aufnahmevorrichtungen zu den Raster- oder Druckwalzen erleichtert. Wenn die Ausrichtung der Aufnahmevorrichtungen besonders gut ist, kann der Sleeve direkt von der Walze auf die Aufnahmevorrichtung herübergeschoben werden, wobei der Sleeve stets entweder von der Aufnahmevorrichtung, der Walze oder beiden Bauteilen zusammen getragen wird. Zu diesem Zweck ist es notwendig, dass der Abstand zwischen dem freien Ende der Aufnahmevorrichtung und dem freien Ende der Walze oder deren Welle kleiner ist als die axiale Länge des Sleeves.As mentioned above, the replacement work which the operator has to perform is facilitated by any improvement in the orientation of the pickup devices to the screen or platen rollers. If the orientation of the receptacles is particularly good, the sleeve can be pushed over directly from the roller onto the receptacle, the sleeve always being carried either by the receptacle, the roller or both components together. For this purpose, it is necessary that the distance between the free end of the receiving device and the free end of the roller or its shaft is smaller than the axial length of the sleeve.

Um die Realisierung dieser vorteilhaften Ausführungsform zu erleichtern, können auch schubladenartige Einschübe zur Verlängerung der Ladefläche der Aufnahmevorrichtungen vorgesehen sein. Diese Einschübe können die Aufnahmevorrichtung beim Wechseln der Sleeves in Richtung auf das freie Ende der Walzen verlängern und auf diese Weise den Sleeve während des Sleevewechsels tragen, so dass das Bedienpersonal entlastet wird. Bei der Verwendung von Tragedornen als Aufnahmevorrichtung bestehen diese Einschübe in der Regel aus Rohren, welche bei Bedarf aus den Tragedornen herausgezogen werden können. Auch diese spezielle Ausführungsform wird in der gegenständlichen Beschreibung weiter gewürdigt.To facilitate the realization of this advantageous embodiment, drawer-like inserts can be provided for extending the loading surface of the receiving devices. These trays can extend the receiving device when changing the sleeves towards the free end of the rollers and thus wear the sleeve during Sleevewechsels, so that the operating staff is relieved. When using support pins as a receiving device, these inserts usually consist of tubes, which can be pulled out of the support mandrels if necessary. This particular embodiment is further appreciated in the subject description.

Insbesondere bei der Verwendung von Tragedornen als Aufnahmevorrichtung ist es vorteilhaft, wenn die Achse der Druckwalzen bei dem Sleevewechsel auch tatsächlich mit der Achse des zugeordneten Tragedorns fluchtet. Dann kann der Abstand zwischen dem Ende der Tragedorne und dem freien Ende der zugeordneten Walze beim Wechselvorgang extrem reduziert werden. Der Sleeve wird dann nur noch von der Walze auf den Dorn oder vom Dorn auf die Walze herübergezogen.In particular, when using support pins as a receiving device, it is advantageous if the axis of the pressure rollers in the sleeve change is actually aligned with the axis of the associated support mandrel. Then the distance between the end of the mandrels and the free end of the associated roller can be extremely reduced during the exchange process. The sleeve is then pulled over only from the roller to the mandrel or from the mandrel to the roller.

Das in den Figuren 1, 3, 6 und 7 dargesfellte Magazin weist keine Mittel zur Veränderung der Position der Aufnahmevorrichtung auf und repräsentiert daher nicht die Erfindung.That in the FIGS. 1 . 3 . 6 and 7 The illustrated magazine has no means for changing the position of the recording device and therefore does not represent the invention.

Fig. 1 zeigt eine Druckmaschine 1 von der exemplarisch zwei Farbwerke 25, 26 dargestellt sind, die durch die Aussparungen 9 im Seitengestell 2 sichtbar sind. Wesentliche Bestandteile eines Farbwerks sind die Rasterwalze 13 und die Druckwalze 16, die jeweils auf dem Lagerbock für Rasterwalze 11 oder dem Lagerbock für Druckwalze 14 über ein Abfanglager 23, 24 gelagert sind. Durch die untere Aussparung 9 ist zusätzlich ein Ausschnitt des Gegendruckzylinders 10 zu sehen. Fig. 1 shows a printing machine 1 of the example two inking units 25, 26 are shown, which are visible through the recesses 9 in the side frame 2. Essential components of an inking unit are the anilox roller 13 and the pressure roller 16, which are each mounted on the bearing block for anilox roller 11 or the bearing block for pressure roller 14 via a capture bearing 23, 24. Through the lower recess 9, a section of the impression cylinder 10 can be seen in addition.

Zum Auswechseln eines Rasterwalzensleeves 12 oder eines Druckwalzensleeves 15 im oberen Bereich der Druckmaschine 1 wird zunächst das Trittblech 6 entlang der Richtung des Pfeils A händisch verschoben, so dass es sich anschließend unterhalb des zu erreichenden Druckwerks befindet. Das Trittblech 6 ist dazu in dem Podest 3 verschieblich gelagert. Aus Stabilitätsgründen ist das Podest 3 über eine Stütze 4 zusätzlich am Seitengestell 2 abgestützt. Auf der dem positionierten Trittblech 6 gegenüber liegenden Seite wird die Treppe 5 ausgeklappt. Das Bedienpersonal kann nun über die Treppe 5 und das Trittblech 6 eines der oberen Farbwerke 25 erreichen. Um den Aufstieg zu erleichtern, sind am Seitengestell 2 Treppengeländer 8 angebracht. Ein Hinabfallen vom Trittblech 6 wird durch ein Seitengeländer 7 verhindert.To replace an anilox sleeve 12 or a pressure roller sleeve 15 in the upper region of the printing press 1, first the tread plate 6 is moved manually along the direction of the arrow A, so that it is then below the printing unit to be reached. The footplate 6 is displaceably mounted in the pedestal 3. For reasons of stability, the pedestal 3 is supported by a support 4 in addition to the side frame 2. On the side facing the positioned tread plate 6, the staircase 5 is unfolded. The operator can now reach via the staircase 5 and the tread plate 6 of the top 25 inking units. To facilitate the ascent, 2 banisters 8 are attached to the side frame. Falling off the footplate 6 is prevented by a side railing 7.

Befindet sich das zu erreichende Farbwerk im unteren Bereich der Druckmaschine, so wirkt das Trittblech 6 und die Treppe 5 störend. DasIf the inking unit to be reached is located in the lower region of the printing press, the footplate 6 and the staircase 5 are disturbing. The

Trittblech 6 kann zur jeweils anderen Seite des Gegendruckzylinders bewegt und die Treppe 5 in ihre vertikal Parkposition geklappt werden. Das Druckwerk ist nun frei zugänglich.Tread plate 6 can be moved to the other side of the impression cylinder and the staircase 5 are folded into their vertical parking position. The printing unit is now freely accessible.

Die zur Durchführung eines Sleevewechselvorganges notwendigen Maßnahmen sind in Figur 3 gut zu erkennen. Nach dem Öffnen der vorderseitigen Abfanglager 23, 24 können die Lagerböcke 11, 14 seitlich verschoben werden, so dass der Druckwalzensleeve 15 und/oder der Rasterwalzensleeve 12, die auf der Druckwalze 16 oder der Rasterwalze 13 aufgeschoben sind, erreicht werden können. Die Sleeves 15, 12 können nun händisch von den Walzen 13, 16 abgezogen werden.The measures necessary for carrying out a sleeve change process are described in US Pat FIG. 3 clearly visible. After opening the front-side Abfanglager 23, 24, the bearing blocks 11, 14 can be moved laterally so that the Druckwalzensleeve 15 and / or the Rasterwalzensleeve 12, which are pushed onto the pressure roller 16 or the anilox roller 13, can be achieved. The sleeves 15, 12 can now be removed manually from the rollers 13, 16.

Zum Abtransport der Sleeves 12, 15 wird ein Magazin für Sleeves 17 mit Tragedornen 18, das mit nicht dargestellten Rollen zum Verfahren ausgestattet sein kann, mit Hilfe eines Kranes 19 angehoben. Dieser Kran 19 besteht im wesentlichen aus einer Wickelrolle und einem Motor. Der Kran 19 ist auf einem Schlitten entlang der parallel zum Seitengestell verlaufenden Laufschiene 21 verschieblich, wodurch die Bewegung der Aufnahmevorrichtungen 18 in horizontaler Richtung (x) sichergestellt wird. In dem gezeigten Ausführungsbeispiel wird das Regal 17, das auf drei Seiten geschlossen und auf einer Seite offen ist, derart am Kran angebracht, dass die Tragedorne 18 parallel zu den Walzen 13, 16 verlaufen und die offene Seite des Magazins 17 zur Druckmaschine 1 zeigt, wie dies in Fig. 3 dargestellt ist. Wie erwähnt ist das auf der Laufschiene 21 gleitende Hebezeug 19 und mit ihm das Magazin 17 in Richtung des Doppelpfeiles in horizontaler Richtung (x) parallel zum Seitengestell 2 verschiebbar. Bei einer günstigen Positionierung des Magazins 17 braucht das Bedienpersonal 33 die Sleeves 12, 15 nur mehr über äußerst kurze Wege zu bewegen.To remove the sleeves 12, 15, a magazine for sleeves 17 with support pins 18, which can be equipped with rollers not shown for the process, raised by means of a crane 19. This crane 19 consists essentially of a winding roll and a motor. The crane 19 is slidable on a carriage along the running parallel to the side frame running rail 21, whereby the movement of the receiving devices 18 in the horizontal direction (x) is ensured. In the exemplary embodiment shown, the shelf 17, which is closed on three sides and open on one side, is attached to the crane in such a way that the carrying mandrels 18 run parallel to the rollers 13, 16 and show the open side of the magazine 17 to the printing machine 1, like this in Fig. 3 is shown. As mentioned, the hoist 19 sliding on the running rail 21 and with it the magazine 17 in the direction of the double arrow in the horizontal direction (x) is displaceable parallel to the side frame 2. With a favorable positioning of the magazine 17, the operator 33 needs to move the sleeves 12, 15 only over extremely short distances.

Um das erneute Positionieren des gesamten Magazins 17 überflüssig zu machen, wenn im gleichen Arbeitsgang neue Sleeves 12, 15 auf die Druckwalze 16 oder die Rasterwalze 13 aufgeschoben werden sollen, kann das Regal 17 mit Tragedornen 18 ausgestattet sein, die den gleichen Abstand wie die Achsen der beiden Zylinder 13, 16 im voneinander abgefahrenen Zustand aufweisen.In order to make the repositioning of the entire magazine 17 superfluous, if in the same operation new sleeves 12, 15 are to be pushed onto the pressure roller 16 or the anilox roller 13, the shelf 17 may be equipped with support pins 18, which are the same distance as the axes of the two cylinders 13, 16 in each other abfahrenen state.

Die Figuren 6 und 7 zeigen das Ausführungsbeispiel des Magazins 17 in detaillierter Form. Dieses Ausführungsbeispiel ist auch in den Figuren 1 und 3 gezeigt.The FIGS. 6 and 7 show the embodiment of the magazine 17 in more detail. This embodiment is also in the FIGS. 1 and 3 shown.

Dieses Magazin 17 besteht aus einem nur auf einer Seite offenen Kasten 32, in dem Tragedorne 18 zur Aufnahme von Sleeves 12, 15 matrixartig aufgereiht sind. Der Abstand der beiden Tragedorne 18 einer (horizontalen) Zeile entspricht dem Abstand der Achsen der Farb- 16 und Druckwalzen 13 eines Farbwerkes 25, 26.This magazine 17 consists of a box open only on one side 32, in the support pins 18 for receiving sleeves 12, 15 are lined up like a matrix. The distance between the two support pins 18 of a (horizontal) line corresponds to the distance between the axes of the inking and printing rollers 13 and 13 of an inking unit 25, 26th

Beim Austausch von Sleeves wird das gesamte Magazin mit Hilfe des Krans 19 und der Schiene 21 so positioniert, dass die Achsen der vorgenannten Walzen 13, 16 eines Farbwerkes 25, 26 mit den zugeordneten leeren Tragedornen 18 einer Ebene fluchten. Die Sleeves werden auf die Tragedorne herübergeschoben. Anschließend wird die vertikale Position des gesamten Magazins mit dem Kran so verändert, dass die beiden Tragedorne mit den neu in das Farbwerk einzubringenden Sleeves 12, 15 mit den Achsen der beiden vorgenannten Walzen fluchten. Daraufhin werden die Walzen mit diesen Sleeves gerüstet. Figur 6 zeigt einen Schnitt, welcher die Funktion der Einschübe 29 verdeutlicht. Diese sind insbesondere bei dem Sleevewechselvorgang zum Tragen des Sleeves gedacht. Durch ein Ausfahren des Einschubs 29 wird das freie Ende 31 der Sleeveaufnahmevorrichtung 18 beim Sleevewechsel in Richtung auf das freie Ende 13 der Walzen 16, 13 oder deren Wellen bewegt.When exchanging sleeves, the entire magazine with the help of the crane 19 and the rail 21 is positioned so that the axes of the aforementioned rollers 13, 16 of an inking unit 25, 26 are aligned with the associated empty support mandrels 18 of a plane. The sleeves are pushed over onto the support pins. Subsequently, the vertical position of the entire magazine with the crane is changed so that the two support pins are aligned with the newly introduced into the inking sleeves 12, 15 with the axes of the two aforementioned rollers. Then the rollers are equipped with these sleeves. FIG. 6 shows a section illustrating the function of the slots 29. These are intended especially for the Sleevewechselvorgang for wearing the sleeve. By extending the insert 29, the free end 31 of the sleeve receiving device 18 is moved during the sleeve change in the direction of the free end 13 of the rollers 16, 13 or their shafts.

Die Figuren 2, 4 und 5 zeigen ein anderes Magazin 17, welches in einer erfindungsgemäßen Sleevewechselvorrichtung Verwendung finden kann.The Figures 2 . 4 and 5 show another magazine 17, which can be used in a sleeve change device according to the invention.

Dieses Magazin enthält Mittel zur Veränderung der Position der Aufnahmevorrichtungen - hier ebenfalls Tragedorne 18 - in dem Magazin 17. Diese Mittel bestehen im wesentlichen aus einer rotierbaren Scheibe 20, an der die Tragedorne angebracht sind, wie dies in Figur 2 dargestellt ist. Die Rotationsachse A der Scheibe verläuft parallel zu der Richtung der Tragedorne 18. Auf diese Weise ist es möglich, durch Rotation der Scheibe 20 die gewünschten Sleeves 12, 15 bereits in die zum Aufschieben auf die Walzen günstigste Position zu bringen. Auch auf dieser Scheibe ist jeweils ein Dorn 18, welcher Rasterwalzensleeves trägt, jeweils einem zu Dorn, welcher Druckwalzensleeves trägt, so beabstandet, dass sich die beiden vorgenannten Tragedorne gleichzeitig mit den beiden Walzen 13, 16 eines Farbwerks in eine fluchtende Position bringen lassen. Der Vorteil dieser Art des Magazinaufbaus gegenüber der in den Figuren 6 und 7 gezeigten Bauart besteht darin, dass während des Sleevewechsels keine Veränderung der Position des gesamten Magazins 17 zur Druckmaschine 1 erfolgen muss, um die mit den Sleeves des abgearbeiteten Auftrags beladenen Tragedorne aus der mit den Walzen fluchtenden Position zu bringen. Dieser Vorgang wird durch eine einfache Drehung der Scheibe, welche von dem Motor 27 und dem Drehmomentübertragungsrad 28 durchgeführt wird, bewerkstelligt. Am Ende der Drehung des Rades fluchten die Tragedorne mit den "neuen" Sleeves 15, 12 mit den Achsen der Walzen 17, 16.

These means consist essentially of a rotatable disc 20 to which the support pins are attached, as shown in FIG. 2 is shown. The axis of rotation A of the disc is parallel to the direction of the support pins 18. In this way it is possible by rotation of the disc 20, the desired sleeves 12, 15 already in the for pushing on the rollers to bring the most favorable position. Also on this disc is in each case a mandrel 18 which carries Rasterwalzensleeves, each one to mandrel, which carries Druckwalzensleeves, spaced so that the two aforementioned support mandrels can bring simultaneously with the two rollers 13, 16 of an inking unit in an aligned position. The advantage of this type of magazine structure over in the FIGS. 6 and 7 The design shown is that during the Sleevewechsels no change in the position of the entire magazine 17 must be made to the printing press 1 to bring the loaded with the sleeves of the processed order Tragedorne from the aligned with the rollers position. This process is accomplished by a simple rotation of the disc, which is performed by the motor 27 and the torque transmission wheel 28. At the end of the rotation of the wheel, the support pins align with the "new" sleeves 15, 12 with the axes of the rollers 17, 16.
