Die Erfindung betrifft ein Verfahren und eine
Vorrichtung zur Durchführung des Verfahrens zur
Bereitstellung von einer auf einem Plattenzylinder zu
montierenden Druckplatte gemäß dem Oberbegriff der
Ansprüche 1 und 4.The invention relates to a method and
Device for performing the method for
Deployment of one on a plate cylinder too
mounting pressure plate according to the preamble of
Aus der DE 42 19 822 A1 ist ein Verfahren und eine Vorrichtung zur Montage von Druckplatten bekannt. Dort wird eine zu montierende Druckplatte von einer Bereitstellungseinrichtung in Reichweite eines Roboters bereitgestellt. Die Bereitstellungseinrichtung ist ein ortsfestes Gestell mit einer Hakenschiene, in die die Druckplatte eingehängt wird. Von dort wird die Druckplatte von dem Roboter in Nähe des Zylinders transportiert und auf dem Zylinder montiert.DE 42 19 822 A1 describes one method and one Device for mounting printing plates known. There is a pressure plate to be assembled from a Provisioning device within reach of a robot provided. The provisioning device is a stationary frame with a hook rail into which the Pressure plate is hooked. From there the Pressure plate from the robot near the cylinder transported and mounted on the cylinder.
Nachteilig an dieser Vorrichtung ist, daß der Raum
zwischen zwei Druckwerken sehr eingeschränkt und eine
Zugänglichkeit der Druckwerke wesentlich erschwert wird.
Zusätzlich wird die Zugänglichkeit des Druckwerkes noch
durch eine Einrichtung zur Abstützung eines Endes der
Druckplatte behindert.
Besonders nachteilig ist, daß der Roboter komplizierte
mehrachsige Bewegungen, beispielsweise Schwenkbewegungen
zum Transport der Druckplatte ausführen muß und damit
aufwendig und teuer baut.A disadvantage of this device is that the space between two printing units is very limited and access to the printing units is made considerably more difficult. In addition, the accessibility of the printing unit is still hindered by a device for supporting one end of the printing plate.
It is particularly disadvantageous that the robot has to carry out complicated multi-axis movements, for example swiveling movements for transporting the printing plate, and is therefore complex and expensive.
Die JP 1-176 558 und US 47 27 807 A zeigen Vorrichtungen, bei denen eine Druckplatte hängend vorpositioniert wird. Diese Druckplatte wird anschließend von einer mehrachsigen Handhabungseinrichtung auf einen Plattenzylinder montiert.JP 1-176 558 and US 47 27 807 A show Devices where a printing plate is hanging is prepositioned. This printing plate will then from a multi-axis Handling device on a plate cylinder assembled.
Die US 44 17 514 A beschreibt ein Verfahren zur Bereitstellung einer Druckplatte mittels einer Befestigungsleiste. Diese Befestigungsleiste wird mit der Druckplatte auf dem Plattenzylinder montiert.US 44 17 514 A describes a method for Provision of a printing plate by means of a Mounting strip. This mounting bar comes with the pressure plate mounted on the plate cylinder.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Durchführung des Verfahrens zur Bereitstellung einer Druckplatte zur Montage auf einem Plattenzylinder einer Rotationsdruckmaschine zu schaffen, bei dem eine Handhabungseinrichtung zum Transport der Druckplatte von einer Warteposition bis zum Einhängen der Druckplatte in eine Befestigungseinrichtung des Plattenzylinders kurze Wege zurücklegt, wobei gleichzeitig eine einfache Bereitstellung der Druckplatte ermöglicht wird, ohne die Zugänglichkeit der Druckwerke einzuschränken.The invention has for its object a method and an apparatus for performing the method for Provision of a pressure plate for mounting on a Plate cylinder of a rotary printing press create in which a handling device for Transport of the printing plate from a waiting position to for hanging the pressure plate in a Fastening device of the plate cylinder short distances covers, while at the same time a simple Deployment of the printing plate is made possible without the Restrict access to the printing units.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren
und eine Vorrichtung zur Durchführung des Verfahrens mit
den Merkmalen der kennzeichnenden Teile der Ansprüche 1
und 4 gelöst.According to the invention, this object is achieved by a method
and an apparatus for performing the method with
the features of the characterizing parts of
In besonders vorteilhafter Weise wird ein vorhandener
Farbwerkschutz als
Druckplattenbereitstellungseinrichtung benutzt, so daß
kein zusätzlicher Platzbedarf notwendig ist.
Durch eine Zwischenspeicherung der Druckplatten in Nähe
des Plattenzylinders erfolgt der Wechsel der
Druckplatten sehr schnell, da eine
Handhabungseinrichtung nur kurze Wege zum Transport und
Montage der Druckplatten zurücklegen muß. Somit ist eine
erhebliche Rüstzeitverkürzung der Druckmaschinen
möglich. Die notwendige Handhabungseinrichtung zur
Montage und Transport muß sich nur in einer Ebene
bewegen, komplizierte Schwenkbewegungen sind daher nicht
notwendig.
Vorteilhafterweise erfolgt ein Einhängen der Druckplatte
in die Druckplattenbereitstellungseinrichtung in einer
zylinderfernen Position, wodurch eine gute, gefahrfreie
Zugänglichkeit sowohl für eine manuelle Bedienung als
auch für automatische Transportsysteme möglich wird.In an especially advantageous manner, an existing inking unit protection is used as a printing plate preparation device, so that no additional space is required. By temporarily storing the printing plates in the vicinity of the plate cylinder, the printing plates are changed very quickly, since a handling device only has to travel short distances to transport and assemble the printing plates. This enables a significant reduction in makeready times. The handling device required for assembly and transport only has to move in one plane, so complicated pivoting movements are not necessary.
The printing plate is advantageously hooked into the printing plate preparation device in a position remote from the cylinder, as a result of which good, risk-free accessibility is possible both for manual operation and for automatic transport systems.

Ein Plattenzylinder 1 einer Rotationsdruckmaschine ist
um seine Zylinderachse 2 drehbar in Seitengestellen 3, 4
gelagert. Dieser Plattenzylinder 1 ist mit
Befestigungseinrichtungen 6, 7, 8, 9 zur Aufnahme von
Druckplatten 11 versehen. Im vorliegenden Beispiel sind
in dem Plattenzylinder 1 in axialer Richtung, parallel
zur Zylinderachse 2 verlaufend vier
Befestigungseinrichtungen 6, 7, 8, 9 angeordnet. Die
Länge der Befestigungseinrichtungen 6, 7, 8, 9 beträgt
jeweils ca. halbe Zylinderlänge. Diese
Befestigungseinrichtungen 6, 7, 8, 9 sind nochmals auf
Druckplattenbreite unterteilt (d. h. pro
Befestigungseinrichtung 6, 7, 8, 9 sind jeweils zwei
Druckplatten 11 vorgesehen) und sind sowohl innerhalb
dieser Unterteilung als auch untereinander unabhängig
betätigbar. Die Befestigungseinrichtungen 6, 7, 8, 9
sind in Umfangsrichtung des Plattenzylinders 1 um ca.
90° zueinander versetzt. Jeder Befestigungseinrichtung
6, 7 ist jeweils eine Befestigungseinrichtung 8, 9
gegenüberliegend zugeordnet.A
Zur Montage, Demontage und zum Transport von
Druckplatten 11 ist eine Handhabungsvorrichtung 12 in
den Seitengestellen 3, 4 angeordnet. Die
Handhabungsvorrichtung 12 besteht im wesentlichen aus
gestellfesten Linearantrieben 13, 14, einer parallel zu
der Zylinderachse 2 axial erstreckenden Traverse 16 und
einer Anzahl, z. B. wie im vorliegenden Beispiel vier,
Greifereinrichtungen 17. An der von den synchronisierten
Linearantrieben 13, 14 bewegten Traverse 16 sind die
Greifeinrichtungen 17 befestigt. Somit werden die
Greifeinrichtungen 17 in einer Transportebene 18 bewegt,
die parallel sowohl zu den Linearantrieben 13, 14 als
auch zu einer von Plattenzylinder 1 und der
vorpositionierten Druckplatte 11 festgelegten Tangente
verläuft.For assembly, disassembly and transport of
Die verwendeten Druckplatten 11 sind mit vorderen und
hinteren Einhängeabkantungen 19, 21 versehen, die mit
den Befestigungseinrichtungen 6, 7, 8, 9 zusammenwirken.
Die Einhängeabkantungen 19, 21 sind formstabil
ausgebildet und weisen jeweils Schenkel 22, 23 auf, die
einen öffnungswinkel Alpha, z. B. 45°, aufweisen.
Abhängig von diesem öffnungswinkel Alpha und einer Länge
der Schenkel 22, 23 ergibt sich eine Höhe h21 der
Einhängeabkantungen 19, 21.The
Dem Plattenzylinder 1 ist ein zylindernaher
Farbwerkschutz 24 zugeordnet, der in den Seitengestellen
3, 4 mittels zylindernaher Achszapfen 26 nach oben
schwenkbar gelagert ist. Dieser Farbwerkschutz 24 ist
als zylinderlanger Druckplattenspeicher 24, bestehend
aus Abführschacht 27 und
Druckplattenbereitstellungseinrichtung 28, ausgebildet.
Der Abführschacht 27, der zur Aufnahme gebrauchter
Druckplatten 11 dient, weist eine obere und eine untere,
gegenüberliegende Wand 29, 31 auf, wobei der
Abführschacht 27 an seinem zylindernahen Ende
annähernd parallel zu der Transportebene 18 der
Druckplatte 11 ausgeführt ist. An dieses gerade,
zylindernahe Ende schließt sich ein viertelkreisförmiger
Abschnitt an, der wieder in ein geraden Teil mündet. Am
Druckplattenspeicher 24 ist die
Druckplattenbereitstellungseinrichtung 28 bezüglich der
Zylinderachse 2 schwenkbar gelagert. Die
Druckplattenbereitstellungseinrichtung 28 weist zu
beiden Seiten des Abführschachtes 27 jeweils einen
Schwenkarm 32 auf, die mit dem Druckplattenspeicher 24
mittels Achszapfen 33 schwenkbar verbunden sind. Diese
Schwenkarme 32 sind an ihrem zylindernahen Ende durch
eine erste Einhängeleiste 34 verbunden. Diese
Einhängeleiste 34 erstreckt sich axial, parallel zur
Zylinderachse 2 und weist nasenförmigen Querschnitt auf.
Der Querschnitt ist in Richtung des Plattenzylinders 1
der vorderen Einhängeabkantung 19 der Druckplatte 11
angepaßt. Im vorliegenden Beispiel ist eine
Auflagefläche 36 der Einhängeleiste 34 parallel zur
Transportebene 18 ausgebildet und eine daran in Richtung
des Plattenzylinders 1 anschließende Einhängefläche 37
schließt mit der Auflagefläche 36 einen öffnungswinkel
Beta von z. B. 45° ein. Ein vom Plattenzylinder 1
wegweisendes Ende der Einhängeleiste 34 ist mit einer
Fase 38 versehen, die derart ausgebildet ist, daß eine
Höhe h38 der Fase 38 bzgl. der Auflagefläche 36 größer
als eine Höhe h21 der hinteren Einhängeabkantung 21 der
Druckplatte 11. Somit dient die Fase 38 der
Einhängeleiste 34 als Führungsfläche für die hintere
Einhängeabkantung 21 der Druckplatte 11. Zusätzlich zur
ersten Einhängeleiste 34 kann wie im vorliegenden
Beispiel in einem Abstand a eine zweite, zylinderferne
Einhängeleiste 39 zwischen den Schwenkarmen 32 befestigt
sein. Sie kann aber auch eigene Schwenkarme 32 aufweisen
und somit unabhängig von der ersten Einhängeleiste 34
schwenkbar gelagert sein. Diese zweite Einhängeleiste 39
dient zur Aufnahme einer zweiten, neuen Druckplatte 40.The
Die Einhängeleisten 34, 39 sind mit nichtdargestellten
Anschlägen zur axialen Positionierung der Druckplatten
11, 40 versehen. Die
Druckplattenbereitstellungseinrichtung 28 ist mittels
nichtdargestellter Antriebe von einer zylindernahen
Warteposition "W", die zur Montage der Druckplatten 11
auf dem Plattenzylinder 1 dient, in eine zylinderferne
Bereitstellungspositon "B", die zum Auflegen der
Druckplatten 11 auf die Einhängeleiste 34, 39 dient,
schwenkbar.
In der Warteposition "W" ist die Auflagefläche 36 der
Einhängeleiste 34 annähernd parallel zur Transportebene
18, d. h. die Einhängeleiste 34 und damit liegt die
Druckplatte 11 in dargestellten Beispiel annähernd
horizontal. Durch das Schwenken der
Druckplattenbereitstellungseinrichtung 28 um ca. 90°
wird eine Bereitstellungspositon "B" erreicht in der die
Auflagefläche 36 der Einhängeleiste 34 und damit die
Druckplatte 11 annähernd vertikal steht. Sind zwei
Einhängeleisten 34, 39 vorgesehen, sind diese in der
Bereitstellungspositon "B" derart in vertikaler Richtung
gesehen versetzt, daß sich zwischen der eingehängten
ersten Druckplatte 11 und der zweiten Einhängeleiste 39
ein Zwischenraum der Breite b ergibt. The
In the waiting position "W", the
Das Einhängen der Druckplatten 11, 40 kann manuell
erfolgen oder wie im vorliegenden Beispiel angedeutet
mittels einer Zuführeinrichtung 41. Diese
Zuführeinrichtung 41 kann aus einem 3 Achsen-Roboter 41
bestehen, dessen erste Achse in Richtung der
Zylinderachse 2, dessen zweite Achse in vertikaler
Richtung und dessen dritte Achse in horizontaler
Richtung liegt. Dieser Roboter 41 ist mit einem
Sauggreifer 42 zur Aufnahme der Druckplatten 11, 40
versehen.The mounting of the
Der Roboter 41 führt eine am Sauggreifer 42 befestigte
Druckplatte 11, 40 in eine bezüglich des
Plattenzylinders 1 vorbestimmte, axiale Position. Nach
Erreichen der axialen Position wird eine der Lage der
Einhängeleiste 34 horizontale Position z. B. mittels
eines Pneumatikzylinders 43 angefahren, worauf z. B.
mittels eines zweiten Pneumatikzylinders 44 eine
vertikale Position erreicht wird. Die neue, erste
Druckplatte 11 wird somit mit ihrer vorderen
Einhängeabkantung 19 in die Einhängeleiste 34 vertikal
und axial vorpositioniert eingehängt.
Dieser Vorgang kann in verschiedenen axialen Positionen
mit weiteren Druckplatten 11 mehrfach wiederholt werden,
um die für den Plattenzylinder 1 in axialer Richtung
benötigten Druckplatten 11 einzuhängen.
Ist eine zweite Einhängeleiste 39 vorgesehen, verläuft
dieser Einhängevorgang entsprechend dem ersten, nur mit
der der zweiten Einhängeleiste 39 angepaßten vertikalen
Position des Sauggreifers 42 des Roboters 41.The
This process can be repeated several times in different axial positions with
If a second hanging
Ist die gewünschte Anzahl von Druckplatten 11, 40 in die
Einhängeleiste 34 eingehängt, schwenkt die
Druckplattenbereitstellungseinrichtung 28 mit ihren
Einhängeleisten 34, 39 um ca. 90° von ihrer
Bereitstellungspositon "B" in ihre Warteposition "W",
womit die eingehängten Druckplatten 11, 40 annähernd
parallel zur Transportebene 18 liegen, d. h.
annähernd horizontal.Is the desired number of
Die Handhabungsvorrichtung 12 kann diese so
vorpositionierten Druckplatten 11 erfassen zu einer
Befestigungseinrichtung 6, 7, 8, 9 des Plattenzylinders
1 transportieren und in diese Befestigungseinrichtung 6,
7, 8, 9 einhängen.The handling
Die Bewegung zum Positionieren der Einhängeleisten 34,
39 von der zylindernahen, horizontalen Warteposition "W"
in die zylinderferne , vertikale Bereitstellungspositon
"B" kann anstatt durch die beschriebene Schwenkbewegung
auch mittels einer Führungsbahn, Gelenkkoppeln oder
einer kombinierten Linear-/ Schwenkbewegung erfolgen.
In vorliegenden Beispiel ist jeweils eine Einhängeleiste
34, 39 für alle, z. B. vier, in axialer Richtung
aufzulegende Druckplatten 11, 40 vorgesehen, d. h. alle
nebeneinanderliegenden, zu wechselnden Druckplatten 11,
40 eines in Umfangsrichtung zwei Druckplatten 11, 40
aufweisenden Plattenzylinders 1 werden bei zwei
vorhandenen Einhängeleisten 34, 39 gemeinsam von der
Bereitstellungspositon "B" in die Warteposition "W"
bewegt. Ist nur eine Einhängeleiste 34 vorhanden, kann
der Schwenkvorgang beispielsweise wiederholt werden.
Ebenso ist es aber auch möglich jedem axialen, einer
Druckplatte 11, 40 zugehörigen Zylinderabschnitt eine
eigene, unabhängig schwenkbare
Druckplattenbereitstellungseinrichtung 28 zuzuordnen. The movement for positioning the hanging strips 34, 39 from the horizontal waiting position "W" close to the cylinder into the vertical standby position "B" remote from the cylinder can also take place by means of a guide track, articulated coupling or a combined linear / pivoting movement instead of the described pivoting movement.
