Abstract

Printing plates can be reliably extracted from a plate cylinder with an automatic plate changer even when the plate lock has a very narrow plate gap between the trailing edge and the leading edge of the printing plate. First, the trailing edge of a printing plate is released by the locking member and the printing plate is elastically deformed at the trailing edge. This allows the guide fork of the automatic plate changer to reliably peel the printing plate away from the plate cylinder. In addition, the guide fork may engage the leading edge of the printing plate after the plate lock has been disengaged once more and peel the leading edge away from the plate cylinder by pivoting away from the cylinder.

Description

Die Erfindung betrifft ein Verfahren zur Entnahme einer Druckplatte von einem Plattenzylinder gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method for removing a printing plate from a Plate cylinder according to the preamble of claim 1.

Druckplatten sind üblicherweise dünne Metallfolien mit einer Oberfläche, die ein zu druckendes Bild definiert. Die Druckplatte ist auf einem Plattenzylinder aufgespannt, der in einem Druckwerk drehbar gelagert ist. Nach dem Einfärben der Platte wird die Druckfarbe von der bildgebenden Oberfläche der Druckplatte auf das zu bedruckende Material in einer Rotationsdruckmaschine übertragen. Im Offsetdruck wird das Druckbild von der Druckplatte zunächst auf ein Gummituch und dann vom Gummituch auf das Papier oder einen anderen Bedruckstoff übertragen.Printing plates are usually thin metal foils with a surface that is too printing image defined. The printing plate is clamped on a plate cylinder, which in a printing unit is rotatably mounted. After inking the plate, the printing ink from the imaging surface of the printing plate to the material to be printed in one Rotary press transferred. In offset printing, the print image of Printing plate first on a rubber blanket and then from the rubber blanket to the paper or transfer another substrate.

Die nutzbare Oberfläche der Druckplatte erstreckt sich von ihrer Hinterkante bis zu ihrer Vorderkante. Bei modernen Plattenzylindern wird der Kanal zwischen der Vorder- und Hinterkante der Platte zunehmend schmaler, um so den nicht-druckenden Kanalstreifen auf dem Plattenzylinder zu minimieren.The usable surface of the printing plate extends from its rear edge to its Leading edge. In modern plate cylinders, the channel between the front and The trailing edge of the plate becomes increasingly narrow, so that the non-printing channel strip is open to minimize the plate cylinder.

In der US 5,678,487 ist ein Plattenzylinder mit einem offenen Kanal, in dem ein Plattenarretiermechanismus angebracht ist, beschrieben. Die Vorder- und Hinterkante, d.h. die Kantenabschnitte der Druckplatte, werden in einem gemeinsamen Spalt festgehalten, der zwischen dem Arretiermechanismus und einer Kanalwand im Plattenzylinder gebildet wird. Nach Verriegeln des Arretiermechanismus ist der Spalt zwischen den Kantenabschnitten der Druckplatte sehr schmal.In US 5,678,487 is a plate cylinder with an open channel in which a Disk locking mechanism is attached described. The leading and trailing edge, i.e. the edge sections of the pressure plate are held in a common gap, which is formed between the locking mechanism and a channel wall in the plate cylinder becomes. After locking the locking mechanism, the gap between the Edge sections of the pressure plate very narrow.

Ein Problem, das mit der Verschmälerung des Plattenspalts zusammenhängt, ist die verstärkte Schwierigkeit, verbrauchte oder zu wechselnde Druckplatten mit einem automatischen Plattenwechsler zu entnehmen. Solch ein automatischer Plattenwechsler ist beispielsweise in der US 5,390,603 beschrieben, wohingegen ein Magazin- und Plattenwechselsystem in den US 5,443,006; US 5,495,805 und US 5,537,926 erläutert wird. In diesen Systemen werden alte Druckplatten automatisch vom Plattenzylinder entfernt und in einem Magazin gespeichert. Eine neue Platte wird automatisch aus dem Magazin ausgegeben und für den Beginn eines neuen Druckauftrags auf den Plattenzylinder aufgespannt.One problem related to the narrowing of the plate gap is that increased difficulty, used or changing printing plates with one automatic plate changer. Such is an automatic plate changer described for example in US 5,390,603, whereas a magazine and Plate changing system in US 5,443,006; US 5,495,805 and US 5,537,926 becomes. In these systems, old printing plates are automatically removed from the plate cylinder removed and saved in a magazine. A new plate is automatically created from the Magazine issued and for the start of a new print job on the Plate cylinder clamped.

Zwar funktionieren diese älteren Systeme im Allgemeinen recht zuverlässig, doch waren sie ursprünglich für viel größere Plattenkanäle konstruiert worden. Mit dem Schmalerwerden des Kanals sind allerdings Schwierigkeiten bezüglich des automatischen Plattenwechsels entstanden, da der Zielkanal für den Plattenwechselmechanismus so viel schmäler geworden ist, dass ein zuverlässiges Einführen der Plattenkanten nicht immer gewährleistet ist und die Plattenkanten während der Entnahme durch bekannte Systeme hängen bleiben können.While these older systems generally work fairly reliably, they were they were originally designed for much larger plate channels. With the However, narrowing the channel is a problem with the automatic Plate change occurred because the target channel for the plate change mechanism so much has become narrower that reliable insertion of the plate edges is not always is guaranteed and the plate edges during removal by known systems can get caught.

Demgemäss ist es eine Aufgabe der Erfindung, ein Verfahren zur Entnahme einer Druckplatte vom Plattenzylinder eines Druckwerks bereit zu stellen, durch welches die oben genannten Nachteile der bekannten Vorrichtungen und Verfahren dieser Art vermieden werden und welches es ermöglicht, einen Plattenwechsel auch bei schmalem Plattenspalt zuverlässig durchzuführen.Accordingly, it is an object of the invention to provide a method for removing a To provide printing plate from the plate cylinder of a printing unit, through which the Disadvantages of the known devices and methods of this type mentioned above can be avoided and which enables a plate change even with narrow To perform plate gap reliably.

Das erfindungsgemäße Verfahren zur Entnahme einer Druckplatte von einem Plattenzylinder, der drehbar in einem Druckwerk gelagert ist, wobei eine Hinterkante und eine Vorderkante der Druckplatte von einem Arretierelement in einem Plattenspalt des Plattenzylinders festgehalten werden, ist gekennzeichnet durch die folgenden Verfahrensschritte: Freigabe der Hinterkante einer Druckplatte durch das Arretierelement des Plattenzylinders, plastisches Verformen der Druckplatte an der Hinterkante und Abziehen der Druckplatte und Entfernen der Druckplatte vom Plattenzylinder.The inventive method for removing a printing plate from a Plate cylinder, which is rotatably mounted in a printing unit, a rear edge and a leading edge of the pressure plate by a locking element in a plate gap of the Plate cylinders are held by the following Process steps: release of the rear edge of a pressure plate by the locking element of the plate cylinder, plastic deformation of the pressure plate at the rear edge and Pull off the pressure plate and remove the pressure plate from the plate cylinder.

Gemäß einem zusätzlichen Merkmal der Erfindung kann der Schritt des Lösens das Verschieben einer Spannleiste innerhalb eines offenen Kanals des Plattenzylinders und das Herausfahren einer Auflagefläche der Spannleiste über eine Mantelfläche des Plattenzylinders hinweg umfassen. According to an additional feature of the invention, the step of solving can Moving a clamping bar within an open channel of the plate cylinder and that Moving out a support surface of the tensioning bar over a lateral surface of the Include plate cylinder.

Gemäß einem weiteren Merkmal der Erfindung kann der Schritt des Verformens das Drücken der Druckplatte in Richtung der Mantelfläche des Plattenzylinders in der Nähe der über die Mantelfläche hinausragenden Spannleisten umfassen.According to a further feature of the invention, the step of deforming can Push the pressure plate in the direction of the outer surface of the plate cylinder near the Include clamping bars protruding beyond the lateral surface.

Gemäß einem weiteren Merkmal der Erfindung kann der Schritt des Abziehens das Platzieren einer zu einer automatischen Plattenwechseleinrichtung gehörenden Führungsgabel in die Nähe der plastisch verformten Hinterkante, das Drehen des Plattenzylinders zum Aufschieben der Hinterkante auf die Führungsgabel und das Wegbiegen der Druckplatte vom Plattenzylinder, während die Drehung des Plattenzylinders fortgesetzt wird umfassen.According to another feature of the invention, the stripping step can Placing one belonging to an automatic plate changing device Guide fork near the plastically deformed rear edge, turning the Plate cylinder for pushing the rear edge onto the guide fork and that Bending away the printing plate from the plate cylinder while the rotation of the Plate cylinder will continue to include.

Die Erfindung eignet sich am besten für den Einsatz bei schmalen Plattenkanälen, d.h. dort, wo die Vorder- und Hinterkante der Druckplatte in einem Spalt von weniger als 5 mm, vorzugsweise sogar weniger als 1 mm, festgehalten wird. In den bevorzugten Ausführungsbeispielen gewährleistet die Erfindung, dass die Druckplatte vom automatischen Plattenwechsler zuverlässig aufgenommen wird. Dies garantiert beispielsweise, dass der automatische Plattenwechsel mit Zylindern mit einem schmalen Kanal, welche z.B. in Verbindung mit einem nahtlosen Gummituch verwendet werden, zuverlässig durchgeführt werden kann.The invention is best suited for use with narrow plate channels, i.e. there, where the front and back edges of the pressure plate are in a gap of less than 5 mm, preferably even less than 1 mm. In the preferred Exemplary embodiments, the invention ensures that the pressure plate from automatic plate changer is reliably recorded. This guarantees for example, that the automatic plate change with cylinders with a narrow Channel which e.g. to be used in conjunction with a seamless rubber blanket can be carried out reliably.

Gemäß einem weiteren Merkmal der Erfindung kann die Führungsgabel gedreht werden, damit ihre Spitze die Vorderkante der Druckplatte (die Kante, die zuletzt vom Zylinder entfernt wird) aufgreifen und die Vorderkante vom Arretierelement wegbewegen kann. Durch die Translationsbewegung der Führungsgabel wird die Vorderkante im Wesentlichen vom Plattenspalt weggedrückt.According to a further feature of the invention, the guide fork can be rotated, so that its tip is the front edge of the pressure plate (the edge that last from the cylinder is removed) and the front edge can move away from the locking element. Due to the translational movement of the guide fork, the front edge in the Essentially pushed away from the plate gap.

Fig. 1 zeigt einen Plattenzylinder 1 mit einem Wellenzapfen 2, der um eine drehbare Achse 3 im Maschinengestell eines Druckwerks drehbar gelagert ist. Der Plattenzylinder 1 verfügt über einen offenen Kanal 4, in dem sich ein Arretierelement 5 mit einer Spannleiste 6 befindet.Fig. 1 shows a plate cylinder 1 with a shaft journal 2, which is about a rotatable axis 3 is rotatably mounted in the machine frame of a printing unit. The plate cylinder 1 has via an open channel 4, in which a locking element 5 with a clamping bar 6 located.

Solch ein Plattenzylinder 1 mit einem entsprechenden Arretierelement 5 ist in der US 5,284,093 beschrieben. Eine Druckplatte 7 befindet sich auf dem Plattenzylinder 1. Die Platte 7 erstreckt sich von einem Kantenabschnitt, bezeichnet als Vorderkante 8, entlang der Mantelfläche des Plattenzylinders 1 bis zum gegenüberliegenden Kantenabschnitt, bezeichnet als Hinterkante 9. Diese Definitionen ergeben sich aus der Drehung des Plattenzylinders während des Druckens, die in den Zeichnungen entgegen dem Uhrzeigersinn verläuft. Während des Druckens werden die gebogenen Segmente der Vorderkante 8 und Hinterkante 9 in einem Plattenspalt festgehalten, der zwischen einer Wand des offenen Kanals 4 und der Spannleiste 6 gebildet wird. In verriegeltem Zustand schließt die Spannleiste 6 im Wesentlichen (bis auf eine kleine offene Fuge) durch ihre Auflagefläche, die passend zum Zylinderradius gebogen ist, die Mantelfläche des Plattenzylinders 1 bündig ab. Die Vorder- und Hinterkanten 8, 9 werden im Plattenzylinder 1 festgehalten, um so den Plattenspalt zu minimieren. Der Plattenspalt kann weniger als etwa 5 mm und sogar weniger als 1 mm betragen. Vorzugsweise berühren die Hinterkante 9 und Vorderkante 8 einander, um den Plattenspalt so weit wie möglich zu reduzieren.Such a plate cylinder 1 with a corresponding locking element 5 is in the US 5,284,093. A printing plate 7 is located on the plate cylinder 1. Die Plate 7 extends from an edge portion, referred to as a leading edge 8 the lateral surface of the plate cylinder 1 to the opposite edge section, referred to as the trailing edge 9. These definitions result from the rotation of the Plate cylinder during printing, which is contrary to in the drawings Runs clockwise. During printing, the curved segments of the Front edge 8 and rear edge 9 held in a plate gap between one Wall of the open channel 4 and the tension bar 6 is formed. When locked essentially closes the clamping bar 6 (except for a small open joint) Contact surface that is curved to match the cylinder radius, the lateral surface of the Plate cylinder 1 flush. The front and rear edges 8, 9 are in the plate cylinder 1 so as to minimize the plate gap. The plate gap can be less than about 5 mm and even less than 1 mm. Preferably touch the rear edge 9 and front edge 8 each other to reduce the plate gap as much as possible.

Die Klemmung der Spannleiste 6 kann gelöst werden, indem die Spannleiste 6 axial aus dem Kanal 4 herausbewegt wird. In diesem Kontext bezieht sich der Begriff "axial" auf die Achse des offenen Kanals 4, die sich entlang einer Sekante des Zylinders 1 erstreckt. Beim Herausfahren der Spannleiste 6 aus dem Kanal 4 verbreitert sich der Klemmspalt und die Vorder- und Hinterkante 8, 9 werden freigegeben.The clamping of the clamping bar 6 can be released by the clamping bar 6 axially channel 4 is moved out. In this context, the term "axial" refers to the Axis of the open channel 4, which extends along a secant of the cylinder 1. At the Extending the clamping bar 6 from the channel 4 widens the clamping gap and Front and rear edges 8, 9 are released.

Bezug nehmend auf die detailliertere Ansicht in Fig. 2 in Kombination mit Fig. 1 ist des Weiteren eine Pressleiste 10 abgebildet, die im Allgemeinen dazu eingesetzt wird, die Vorder- und die Hinterkanten 8, 9 der Platte in den Klemmspalt einzufügen, indem sie die Plattenkanten in Richtung des Plattenzylinders 1 drückt. Gemäß der Erfindung kann die Pressleiste 10 dazu verwendet werden, die Druckplatte 7 plastisch zu verformen, um so sicherzustellen, dass ein automatische Plattenwechsler die Platte 7 zuverlässig entnehmen kann. Zu diesem Zweck wird der Plattenzylinder 1 entgegen dem Uhrzeigersinn gedreht, bis die Pressleiste 10 knapp unterhalb der Spannleiste 6 positioniert ist. An diesem Punkt werden sowohl die Pressleiste 10 als auch die Spannleiste 6 mit der dazwischenliegenden Platte betätigt. Die Pressleiste 10 kann auch nach der Spannleiste 6 oder umgekehrt betätigt werden. Da die Spannleiste über den Zylindermantel hinausragt, wird die Platte 7 entlang einer Biegelinie 11 plastisch verformt, so dass sie nach außen und vom Plattenzylinder weg absteht. Die Hinterkante 9 springt nicht mehr in den Klemmspalt zurück, auch dann nicht, wenn die Spannleiste 6 wieder in den Kanal 4 zurückfährt. An diesem Punkt ist die Platte 7 bereit für die Entnahme durch den automatischen Plattenwechsler, und eine Führungsgabel 12 (siehe Fig. 3) des Plattenwechslers kann zuverlässig die Platte ergreifen und beim Drehen des Zylinder 1 im Uhrzeigersinn in das Entsorgungsmagazin überführen. Beim Drehen des Plattenzylinders 1 wird die Hinterkante 9 der Platte 7 (in Fig. 1 nach links) durch die Führungsgabel 12 vom Plattenzylinder 1 weggedrückt.Referring to the more detailed view in FIG. 2 in combination with FIG. 1, the Furthermore, a pressure bar 10 is shown, which is generally used for the Insert the front and rear edges 8, 9 of the plate into the clamping gap by the Press plate edges in the direction of the plate cylinder 1. According to the invention, the Press bar 10 can be used to plastically deform the pressure plate 7, so ensure that an automatic plate changer reliably remove plate 7 can. For this purpose, the plate cylinder 1 is turned counterclockwise, until the pressure bar 10 is positioned just below the tension bar 6. At this point both the pressure bar 10 and the tension bar 6 with the intermediate Plate actuated. The pressure bar 10 can also be operated after the tension bar 6 or vice versa become. Since the tension bar protrudes beyond the cylinder jacket, the plate 7 is along a bending line 11 plastically deformed so that it faces outwards and away from the plate cylinder projects. The rear edge 9 no longer jumps back into the clamping gap, even then, when the tensioning bar 6 moves back into the channel 4. At this point the plate is 7 ready for removal by the automatic plate changer, and a guide fork 12 (see Fig. 3) of the plate changer can reliably take the plate and when Transfer the cylinder 1 clockwise into the disposal magazine. At the Rotating the plate cylinder 1 becomes the rear edge 9 of the plate 7 (to the left in FIG. 1) pushed away from the plate cylinder 1 by the guide fork 12.

Das erfindungsgemäße Verfahren kann ohne den Einbau zusätzlicher Vorrichtungen in das Druckwerk realisiert werden. Die Platte 7 kann mit bestehenden Vorrichtungen dauerhaft verformt werden.The inventive method can without the installation of additional devices in the Printing unit can be realized. The plate 7 can be permanent with existing devices be deformed.

In Fig. 3 ist ein zusätzliches Merkmal der Erfindung dargestellt. Hier ist die Führungsgabel 12 des Plattenwechslers schwenkbar gelagert. Nachdem die Hinterkante 9 durch Ausfahren der Spannleiste 6 freigegeben worden ist, wird der Plattenzylinder 1 im Uhrzeigersinn gedreht, so dass die Platte in den Schacht zwischen Führungsgabel 12 und einer Führung 15 eingeführt wird, bis das vordere Ende der Führungsgabel 12 die Vorderkante 8 der Platte 7 erreicht.3 shows an additional feature of the invention. Here is the guide fork 12 of the plate changer pivotally mounted. After the rear edge 9 by extending the clamping bar 6 has been released, the plate cylinder 1 is clockwise rotated so that the plate in the shaft between guide fork 12 and a guide 15 is inserted until the front end of the guide fork 12, the front edge 8 of the Plate 7 reached.

An diesem Punkt wird die Führungsgabel 12 geringfügig im Uhrzeigersinn gedreht (etwa 5° bis 20°), und aufgrund der translatorischen Bewegung des freien Endes der Führungsgabel 12 springt die Vorderkante 8 der Platte 7 aus dem Spalt heraus. In den meisten Fällen entfernt die Plattenentnahmevorrichtung mit ihren Greifern und/oder Gummisaugem die Druckplatte sicher ohne Hilfe der Bewegung der Führungsgabel. Allerdings besteht in manchen Fällen die Möglichkeit, dass die Vorderkante 8 im Bereich des Spalts hängen bleibt und die automatische Entnahme nicht zufriedenstellend gewährleistet ist. Eine solche Situation erfordert dann den Eingriff des Maschinenbedieners mit der damit verbundenen Zeitverzögerung bei der Plattenentnahme. Der andernfalls ein bis zwei Minuten dauernde automatische Plattenwechsel würde dann beträchtlich länger dauern und die Ausfallzeit zwischen Druckaufträgen wird erheblich verlängert.At this point, the guide fork 12 is rotated slightly clockwise (approximately 5 ° to 20 °), and due to the translational movement of the free end of the Guide fork 12 jumps the front edge 8 of the plate 7 out of the gap. In the in most cases the plate removal device with its grippers and / or removed Rubber suction cups the pressure plate safely without the help of the movement of the guide fork. However, in some cases there is the possibility that the front edge 8 in the area the gap gets stuck and the automatic removal is unsatisfactory is guaranteed. Such a situation then requires intervention by the machine operator with the associated delay in plate removal. The otherwise one Automatic plate changes lasting up to two minutes would then be considerably longer and the downtime between print jobs is significantly increased.

Die Schwenkbewegung der Führungsgabel 12 wird durch einen Pfeil 13 angezeigt. Nach der Freigabe der Vorderkante kann dann der Entnahmeprozess fortgesetzt werden, indem die Platte 7 komplett aus dem Schacht zwischen der Führungsgabel 12 und der Führung 15 gezogen und im entsprechenden Entnahmemagazin platziert wird.The pivoting movement of the guide fork 12 is indicated by an arrow 13. To The release process can then be continued by releasing the leading edge the plate 7 completely out of the shaft between the guide fork 12 and the guide 15 is pulled and placed in the appropriate removal magazine.

In Fig. 4, die eine weitere Variante zeigt, könnte nach Abziehen der Druckplatte 7 vom Plattenzylinder 1 die gebogene Vorderkante 8 der Platte 7 im Schacht 4 hängen bleiben oder sich am vorderen Ende der Führungsgabel 12 verfangen. Es ist deshalb gemäß der Erfindung vorteilhaft, die Vorderkante 8 zurückzubiegen und den Endabschnitt der Platte 7 im Wesentlichen abzuflachen. Dies kann auf verschiedene Weisen erzielt werden. In einem bevorzugten Ausführungsbeispiel wird der Schließmechanismus geschlossen, nachdem sich die Hinterkante 9 sicher in dem Entnahmeschacht zwischen den Führungsgabeln 12 und 15 befindet. Beim Abrollen der Platte 7 vom Plattenzylinder 1 durch Drehen im Uhrzeigersinn und Heranführen der Führungsgabel 12 an die Vorderkante 8, die nach wie vor von der Spannleiste 6 im Plattenspalt festgespannt wird, wird das Plattenmaterial zurückgebogen, um die Vorderkante 8 weitgehend abzuflachen. Die Spannleiste 6 kann nach dem Abflachen der Platte 7 geöffnet und die Platte entnommen werden, ohne dass der sonst hinderliche gebogene Abschnitt die Vorderkante 8 begrenzt. Ein weiterer Vorteil der Beseitigung der Biegung an der Vorderkante 8 zeigt sich, wenn die verbrauchte Druckplatte in das Entnahmemagazin abgelegt wird. Dies wird üblicherweise durch ein Hindurchführen der Platte durch Presswalzen erzielt, welche die gebogenen Plattenkanten "plätten", um so eine gerade Plattenkante zu gewährleisten. Das Vorbiegen mit der Führungsgabel 12 stellt sicher, dass die Presswalzen die Platte nicht in die falsche Richtung biegen und dadurch die Biegung an der Vorderkante tatsächlich verstärken. In Fig. 4, which shows a further variant, after removing the pressure plate 7 from Plate cylinder 1, the curved front edge 8 of the plate 7 get stuck in the shaft 4 or get caught at the front end of the guide fork 12. It is therefore according to the Invention advantageous to bend back the leading edge 8 and the end portion of the plate 7th essentially flatten. This can be accomplished in a number of ways. In one preferred embodiment, the locking mechanism is closed after the rear edge 9 securely in the removal shaft between the guide forks 12 and 15 is located. When rolling the plate 7 from the plate cylinder 1 by turning Clockwise and guiding the guide fork 12 to the front edge 8, which continues is clamped in front of the clamping bar 6 in the plate gap, the plate material bent back to largely flatten the front edge 8. The tension bar 6 can after flattening the plate 7 opened and the plate can be removed without the otherwise obstructive curved section limits the front edge 8. Another advantage of Eliminating the bend on the leading edge 8 shows up when the used one Pressure plate is placed in the removal magazine. This is usually done by a Passing the plate through press rolls achieved the bent plate edges "flatten" to ensure a straight plate edge. Bending with the Guide fork 12 ensures that the press rolls the plate in the wrong direction bend and thereby actually reinforce the bend at the leading edge.
