Abstract

The printing machine has two additional stops (10) which protrude further in the direction of the plate cylinder (1) than the stops (11) associated with the ring (2) on the end sides of the cylinder. When the cylinder is in the appropriate position the additional stops act on same. The stops are formed as screws turned in the threaded bores of the strip which extends parallel to the cylinder axis and is adjustable relative to it. The stops can act on the area of the surface of the cylinder next to the ring, apart from the largest printing plate format.

Description

Die Erfindung betrifft eine Vorrichtung zum Wechseln von Druckplatten gemäß dem Oberbegriff von Anspruch 1.The invention relates to a device for changing printing plates according to the preamble of claim 1.

Aus der DE 4 215 969 B2 ist eine Einführleiste zum Zuführen von Druckplatten bekannt, welche aus einer an den Plattenzylinder an- und bezüglich diesem abstellbar gelagerten Einführschiene besteht. Zum Zuführen einer neuer Druckplatte wird dazu der Plattenzylinder in eine vorgegebene Position verfahren und die Einführschiene an diesen angestellt. Die Vorderkante einer zuzuführenden Druckplatte gleitet nun an der zum Plattenzylinder hinweisenden Einführfläche dieser Einführschiene in den geöffneten Erfassungsbereich einer dem Druckanfang zugeordneten Klemmschiene. Diese Einführschiene weist an ihren beiden Enden je einen Anschlag auf, vermittels der ein Abstützen an den Schmitzringen des Plattenzylinders erfolgt.From DE 4 215 969 B2 an insertion bar for feeding printing plates is known, which consists of an insertion rail which is mounted on the plate cylinder and can be removed with respect to the latter. To feed a new printing plate, the plate cylinder is moved into a predetermined position and the insertion rail is placed against it. The front edge of a pressure plate to be fed now slides on the insertion surface of this insertion rail pointing towards the plate cylinder into the open detection area of a clamping rail assigned to the start of printing. This insertion rail has a stop at each of its two ends, by means of which it is supported on the bearer rings of the plate cylinder.

Aus der DE 4 214 207 C1 ist eine an den Plattenzylinder an- und abstellbar gelagerte Andrückrolle nebst Abkantleiste bekannt. Mittels der Andrückrolle erfolgt das Aufziehen der Druckplatte um den Außenumfang des Plattenzylinders, wobei dieser sich vorwärts dreht. Zum Einführen der nachlaufenden Kante der Druckplatte in die dem Druckende zugeordnet Spannschiene erfolgt das Anstellen der Abkantleiste, wobei dadurch das Biegen der Druckplatte um eine Abkantung am Druckende erfolgt. Diese Abkantleiste weist keine einstellbaren Anschläge auf, so daß die Stärke der der Druckplatte aufgeprägten Abkantung, also die Abwinkelung nicht veränderbar ist.From DE 4 214 207 C1 a pressure roller mounted on and off the plate cylinder and a folding bar is known. The pressure plate is pulled around the outer circumference of the plate cylinder by means of the pressure roller, the latter rotating forwards. In order to insert the trailing edge of the printing plate into the clamping rail assigned to the printing end, the folding bar is set up, whereby the bending of the printing plate takes place by a bend at the printing end. This fold bar has no adjustable stops, so that the thickness of the fold impressed on the pressure plate, that is to say the bending, cannot be changed.

Aus der nicht vorveröffentlichten deutschen Patentanmeldung P 4 339 344.6 ist es bekannt, die Einführschiene mit der Einführfläche zum Zuführen einer neuen Druckplatte direkt an der Abkantleiste zum Biegen des Druckendes der Druckplatte anzubringen. Zum Zuführen einer neuen Druckplatte wird die Andrükrolle mit der Abkantleiste an die Oberfläche der dem Druckanfang zugeordneten Klemmschiene angestellt. Nach dem Aufziehen der Druckplatte um den Außenumfang des Plattenzylinders erfolgt dann wiederum das Anstellen der Abkantleiste und daraufhin das Einführen des nachlaufenden Endes der Druckplatte in die zugeordnete Spannschiene. Auch hier stützt sich die Abkantleiste direkt an der vorderen Klemmschiene bzw. an der Kontur des Druckendes der Plattenzylinders ab, so daß die geforderten geometrischen Verhältnisse zum Zuführen einer neuen Druckplatte bzw. zum Einführen des Druckendes der Druckplatte in die Spannschiene durch eine entsprechende Bauform der miteinander zusammenwirkenden Bauteile zu definieren und somit auch nicht zu verändern sind.From the unpublished German patent application P 4 339 344.6 it is known to attach the insertion rail with the insertion surface for feeding a new printing plate directly to the folding bar for bending the printing end of the printing plate. To feed a new pressure plate, the pressure roller with the folding bar is placed on the surface of the clamping rail assigned to the start of printing. After the pressure plate has been drawn up around the outer circumference of the plate cylinder, the folding bar is again turned on and then the trailing end of the pressure plate is inserted into the assigned tensioning rail. Here, too, the folding bar is supported directly on the front clamping rail or on the contour of the printing end of the plate cylinder, so that the required geometric conditions for feeding a new printing plate or for inserting the printing end of the printing plate into the tensioning rail by means of a corresponding design with one another to define interacting components and therefore not to be changed.

Aufgabe der vorliegenden Erfindung ist es daher eine Vorrichtung gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so daß die Einsetzbarkeit eine dem Wechseln von Druckplatten dienenden Einrichtung erweitert werden kann.The object of the present invention is therefore to extend a device according to the preamble of claim 1 such that the usability of a device serving to change printing plates can be expanded.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1 gelöst. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.According to the invention, this object is achieved by the characterizing features of claim 1. Further developments of the invention result from the subclaims.

Des weiteren erfolgt die Erläuterung eines Ausführungsbeispiels der Erfindung anhand der Zeichnung. Es zeigt:

  • Fig. 1 und 2 die Funktion der beiden Anschläge, um die Abkantleiste in zwei verschiedene Stellungen zum Plattenzylinder zu bringen,
  • Fig. 3 und 4 die durch die beiden Anschläge definierte Stellung der Abkantleiste zum Plattenzylinder in der Druckende- und Druckanfang-Position,
  • Fig. 5 einen Plattenzylinder mit achsparalleler Grube, und
  • Fig. 6 eine Ansicht eines Plattenzylinders mit der sich über die Formatbreite erstreckenden Abkantleiste.
Furthermore, an embodiment of the invention is explained with reference to the drawing. It shows:
  • 1 and 2, the function of the two stops to bring the folding bar in two different positions to the plate cylinder,
  • 3 and 4, the position defined by the two stops of the folding bar to the plate cylinder in the print end and print start position,
  • Fig. 5 shows a plate cylinder with an axially parallel pit, and
  • Fig. 6 is a view of a plate cylinder with the folding bar extending over the format width.

Fig. 5 zeigt einen Plattenzylinder 1 mit einer darin angebrachten achsparallelen Grube 3. An den beiden Stirnseiten des Plattenzylinders 1 weist dieser jeweils einen Schmitzring 2 auf. Diese Schmitzringe 2 wirken mit entsprechenden Ringen eines nicht dargestellten Gummituchzylinders in bekannter Weise zusammen. In der Grube 3 des Plattenzylinder 1 sind jeweils eine dem Druckanfang zugeordnete Spann- bzw. Klemmschiene 4, 5 angeordnet. In der Spann- bzw. Klemmschiene 4, 5 erfolgt das Befestigen und sodann Spannen des Druckanfanges bzw. des Druckendes einer in Fig. 5 nicht gezeigten Druckplatte.FIG. 5 shows a plate cylinder 1 with an axially parallel pit 3 mounted therein. On the two end faces of the plate cylinder 1, the latter has a bearer ring 2. These bearer rings 2 interact with corresponding rings of a blanket cylinder, not shown, in a known manner. In the pit 3 of the plate cylinder 1, a clamping or clamping rail 4, 5 assigned to the start of printing is arranged. In the tensioning or clamping rail 4, 5, the fastening and then tensioning of the printing start or the printing end of a printing plate, not shown in FIG. 5, takes place.

Fig. 6 zeigt einen Plattenzylinder 1 mit einer darauf befindlicher Druckplatte 9. Parallel zur Achse des Plattenzylinders verläuft eine Abkantleiste 7, welche jeweils an den über die Formatgrenzen des Plattezylinders hinausreichenden Enden über eine nicht dargestellte Anstellvorrichtung bezüglich dem Plattezylinder 1 an- und abstellbar getragen ist. Diese An- und Abstellvorrichtung kann dabei beispielsweise aus jeweils einem an der Gestellwand des Druckwerkes angebrachten Lagerhebel bestehen, welche jeweils mit einem Ende der Abkantleiste 7 verbunden sind.6 shows a plate cylinder 1 with a pressure plate 9 located thereon. A folding bar 7 runs parallel to the axis of the plate cylinder and is supported on the ends extending beyond the format limits of the plate cylinder by an adjusting device (not shown) with respect to the plate cylinder 1 . This switch-on and switch-off device can consist, for example, of a bearing lever attached to the frame wall of the printing unit, each of which is connected to one end of the folding bar 7.

An den Enden der Abkantleiste 7 sind außerhalb des größten Druckplattenformates jeweils ein paar einstellbare Anschläge 10, 11 in Form von Schrauben angebracht, vermittels denen sich die Abkantleiste im angestellten Zustand entweder auf dem Schmitzring 2 oder der Oberfläche des Plattenzylinders 1 abstützen kann. Wie in Fig. 1 und 2 zu erkennen, handelt es sich bei den erfindungsgemäßen Anschlägen 10, 11 um Schrauben, die durch entsprechende Gewindebohrungen der Abkantleiste 7 gedreht sind und wobei der Anschlag 10, welcher zum Abstützen auf der Oberfläche des Plattenzylinder 1 dient, weiter in Richtung Plattenzylinder 1 hervorsteht als der Anschlag 11, welcher zum Abstützen der Abkantleiste 7 auf den Schmitzring 2 dient.At the ends of the folding bar 7, a few adjustable stops 10, 11 in the form of screws are attached outside the largest printing plate format, by means of which the folding bar can be supported either on the bearer ring 2 or the surface of the plate cylinder 1 in the engaged state. As can be seen in FIGS. 1 and 2, the stops 10, 11 according to the invention are screws which are rotated through corresponding threaded bores in the folding bar 7 and the stop 10, which is used for support on the surface of the plate cylinder 1, continues protrudes in the direction of the plate cylinder 1 as the stop 11, which serves to support the folding bar 7 on the bearer ring 2.

Die Figuren 3 und 4 zeigen die Stellung der Abkantleiste 7 mit der daran angebrachten Einführschiene 8 gemäß den Figuren 1 und 2. In Figur 3 ist zum Abkanten und Einführen einer Druckplatte 9 in die dem Druckende 9 zugeordneten Spannschiene 4 eine achsparallele und dem Aufziehen der Platte dienende Andrückrolle 6 an den Plattenzylinder angestellt. Über weitere nicht dargestellte Stellmittel (z.B. Pneumatikzylinder) ist die verschwenkbar bezüglich der Andrückrolle 6 gelagerte Abkantleiste 7 an den Plattenzylinder angestellt. Dargestellt ist ferner die Einführschiene 8, welche an der Abkantleiste 7 angebracht ist und welche dem Zuführen einer neuen Druckplatte dient.FIGS. 3 and 4 show the position of the folding bar 7 with the insertion rail 8 attached to it according to FIGS. 1 and 2. In FIG. 3, for folding and inserting a pressure plate 9 into the clamping rail 4 assigned to the printing end 9, an axially parallel and the pulling-up of the plate is shown serving pressure roller 6 placed on the plate cylinder. The folding bar 7, which is pivotably mounted with respect to the pressure roller 6, is placed against the plate cylinder by means of further adjusting means (not shown) (e.g. pneumatic cylinders). Also shown is the insertion rail 8, which is attached to the folding bar 7 and which is used to feed a new printing plate.

In Fig. 3 ist dargestellt. daß der Anschlag 10 in den Bereich der Grube 3 des Plattenzylinders 1 eintaucht und daher ein Abstützen der Abkantleiste 7 über den Anschlag 11 an dem Schmitzring 2 des Plattenzylinders 1 erfolgt.3 is shown. that the stop 10 dips into the area of the pit 3 of the plate cylinder 1 and therefore the folding bar 7 is supported via the stop 11 on the bearer ring 2 of the plate cylinder 1.

In Fig. 4 ist die Stellung der Abkantleiste 7 nebst der Einführschiene 8 zum Zuführen einer neuen Druckplatte 9 in den geöffneten Klemmbereich einer dem Druckanfang zugeordneten Klemmschiene 5 wiedergegeben. Erkennbar ist nun der Plattenzylinder 1 in eine derartige Position verfahren, so daß der weiter in Richtung Plattenzylinder 1 hervortretende Anschlag 10 sich am Umfang des Plattenzylinders 1 abstützt und somit die Klemmleiste 7 nebst der Abkantleiste 8 eine Stellung bezüglich dem Plattenzylinder 1 einnimmt, so daß die Vorderkante der Druckplatte 9 auf der zum Plattenzylinder 1 gewandten Seite der Einführschiene 8 gleitend in den Klemmbereich der Klemmschiene 5 gelangen kann. Da der weiter hervortretende Anschlag 10 aufdem Außenumfang des Plattenzylinder 1 aufliegt, kommt der Anschlag 11 nicht mit der Oberfläche des Schmitzringes 2 in Beführung. Die Situation gemäß Fig. 4 ist nochmals in Fig. 2 in einer anderen Ansicht wiedergegeben.4 shows the position of the folding bar 7 together with the insertion rail 8 for feeding a new pressure plate 9 into the open clamping area of a clamping rail 5 assigned to the start of printing. The plate cylinder 1 can now be seen moved into such a position so that the stop protruding further in the direction of the plate cylinder 1 10 is supported on the circumference of the plate cylinder 1 and thus the clamping bar 7 along with the folding bar 8 assumes a position with respect to the plate cylinder 1, so that the front edge of the pressure plate 9 on the side of the insertion rail 8 facing the plate cylinder 1 slides into the clamping area of the clamping rail 5 can. Since the protruding stop 10 rests on the outer circumference of the plate cylinder 1, the stop 11 does not come into contact with the surface of the bearer ring 2. The situation according to FIG. 4 is shown again in another view in FIG. 2.

Wie bereits weiter obenstehend wiedergegeben, handelt es sich bei den Anschlägen 10 und 11 um Schrauben, welche durch entsprechende Gewindebohrungen in der Abkantleiste 7 gedreht sind. Dadurch ist es möglich, die Abkantleiste 7 in Verbindung mit der daran angebrachten Einführschiene 8 genau definiert einzustellen, also optimale Verhältnisse für das Zuführen einer neuen Druckplatte in die Klemmschiene 5 des Plattenzylinders 1 am Druckanfang zu schaffen. Ebenso ergeben sich optimale Verhältnisse am Druckende des Plattenzylinders. Um ein beschädigungsfreies Absützen der Anschläge 10 und 11 an dem Plattenzylinder 1 bzw. dem Schmitzring 2 zu erzielen, kann ferner vorgesehen sein, das Material der als Schrauben ausgebildeten Anschläge 10, 11 auf das des Plattenzylinders 1 entsprechend abzustimmen.As already reproduced above, the stops 10 and 11 are screws which are rotated through corresponding threaded holes in the folding bar 7. This makes it possible to set the folding bar 7 in connection with the insertion rail 8 attached to it in a precisely defined manner, that is to say to create optimum conditions for feeding a new printing plate into the clamping rail 5 of the plate cylinder 1 at the start of printing. There are also optimal conditions at the printing end of the plate cylinder. In order to achieve damage-free protection of the stops 10 and 11 on the plate cylinder 1 or the bearer ring 2, provision can further be made to match the material of the stops 10, 11 designed as screws with that of the plate cylinder 1 accordingly.

Nach einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, daß am Plattenzylinder 1 den beiden weiteren Anschlägen 10 ,jeweils neben den Schmitzringen 2 liegend, Stützflächen zugeordnet sind. Diese Stützflächen können insbesondere an den Stirnseiten der Schmitzringe 2 angebracht sein und verhindern, daß die Anschläge 10 sich auf der Oberfläche des Plattenzylinders 1 abstützen.According to a further embodiment of the invention it can be provided that on the plate cylinder 1 the two further stops 10, each lying next to the bearer rings 2, are assigned support surfaces. These support surfaces can in particular be attached to the end faces of the bearer rings 2 and prevent the stops 10 from being supported on the surface of the plate cylinder 1.
