In Weiterentwicklung des Standes der Technik liegt der Erfindung die Aufgabe zugrunde, auf eine einfachere Weise als nach dem Stand der Technik eine sogar werkzeuglose Montage und Demontage im Kanal eines Druckformzylinders nebeneinander liegender Halteelemente zu ermöglichen.The invention lies in a further development of the prior art based on the task in a simpler way than after state of the art even tool-free assembly and disassembly lying side by side in the channel of a printing form cylinder To enable holding elements.
Die Erfindung schlägt zu diesem Zweck eine Vorrichtung zur Verbindung von Halteelementen mit einer Traverse eines Druckformzylinders einer Rotationsdruckmaschine zum Fixieren einer biegsamen Druckform auf dem Umfang des Druckformzylinders vor, wobei die Vorderkante der biegsamen Druckform eine Vorderkante eines Kanals des Druckformzylinders übergreift und die Hinterkante der biegsamen Druckform durch mindestens ein an der Traverse betätigbar anordbares, federndes Halteelement fixierbar ist, welches an dem der Umfangsfläche des Druckformzylinders zugewandten Ende einen hakenförmigen Vorsprung aufweist, dadurch gekennzeichnet, daß mehrere, nebeneinander anordbare Halteelemente an der Traverse durch Arretierungen formschlüssig verriegelbar sind.The invention proposes a device for this purpose Connection of holding elements with a traverse of a printing form cylinder a rotary printing press for fixing one flexible printing form on the circumference of the printing form cylinder before, the leading edge of the flexible printing form a Overlaps the front edge of a channel of the printing form cylinder and the trailing edge of the flexible printing form by at least a resilient which can be arranged on the crossbar and can be actuated Holding element is fixable, which on that of the peripheral surface end of the printing form cylinder facing a hook-shaped Has projection, characterized in that several holding elements can be arranged side by side on the crossbar Locks are positively lockable.
Die mit der erfindungsgemäßen Lösung einhergehenden Vorteile liegen unter anderem darin, daß nunmehr ein einwandfreies Verriegeln der Halteelemente bei deren Montage erfolgen kann, was der Bediener auch wahrnimmt und was trotz der räumlichen Beengtheit im Kanal auch verifizierbar ist, da die einzelnen Halteelemente im Kanal nebeneinander liegend angeordnet sind und miteinander fluchten. Schließlich erlaubt die erfindungsgemäße Lösung auch eine vereinfachte Kontrolle, da alle Halteelemente eine definierte Einbaulage einnehmen.The advantages associated with the solution according to the invention are, among other things, that now a flawless Locking the holding elements during assembly can be done what the operator also perceives and what despite the spatial Confinement in the channel is also verifiable as the individual Holding elements are arranged side by side in the channel and cursed with each other. Finally, the invention allows Solution also a simplified control, since all holding elements assume a defined installation position.
In bevorzugter Ausgestaltung der Erfindung sind die Halteelemente in Führungen an der Traverse vertikal einführbar.In a preferred embodiment of the invention, the holding elements Can be inserted vertically in guides on the crossbar.
In dieser bevorzugten Ausgestaltung der Erfindung sind die Halteelemente des weiteren mit Ausnehmungen versehen, die an Stiften einer Traverse nach dem Bajonett-Prinzip verriegelbar sind. Die Verriegelung erfolgt durch eine seitliche Verschiebebewegung, die eine formschlüssige Verbindung zwischen Ausnehmung und jeweils korrespondierendem Stift darstellt. Die Verriegelung kann in einer durch die beiden an der Traverse aufgenommenen Führungen begrenzten Ebene erfolgen. Beim Einführen der Halteelemente in vertikale Richtung übergreifen die Halteelemente die Stifte. Zur Verriegelung einzelner Halteelemente ist eine seitliche Verschiebebewegung dieser erforderlich, so daß im verriegelten Zustand die Halteelemente seitlich aneinander liegend im Kanal angeordnet sind.In this preferred embodiment of the invention, the Holding elements further provided with recesses that Pins on a traverse can be locked according to the bayonet principle are. The locking takes place by a lateral sliding movement, which has a positive connection between the recess and each represents the corresponding pen. The Locking can be done in one by the two on the crossbar guided tours take place at a limited level. When inserting of the holding elements overlap in the vertical direction the holding elements the pins. For locking individual holding elements a lateral shifting movement of these is required, so that the holding elements in the locked state are arranged side by side in the channel.

In der Darstellung gemäß Fig. 1, die einen Querschnitt durch
einen Druckformzylinder 1 im Bereich des Spannkanales wiedergibt,
ist eine hier beispielsweise als Rundstab ausgeführte
Traverse 6 erkennbar, die in einem Spannkanal 5 des Druckformzylinders
1 aufgenommen ist. Ein in die Umfangsfläche des
Druckformzylinders 1 mündender Kanal 2 ist einerseits von einer
Kanalecke 4 und andererseits durch eine Kanalflanke 3 begrenzt.
An der Kanalecke 4 wird eine Vorderkante 8 einer
Druckform 7 und an einem Halteelement 10, welches an der
rückwärtigen Flanke 3 des Kanals 2 anliegt, wird die Hinterkante
9 der Druckform 7 befestigt. Die Druckform 7 wird dann
auf dem Umfang des Druckformzylinders 1 gespannt.1, which is a cross section through
reproduces a printing form cylinder 1 in the area of the clamping channel,
is here, for example, a round bar
Traverse 6 can be seen in a clamping channel 5 of the printing form cylinder
1 is included. One in the peripheral surface of the
Printing form cylinder 1 opening
Das hier gezeigte Halteelement 10 weist einen hakenförmigen
Vorsprung 11 auf, mit welchem die Hinterkante 9 der Druckform
7 untergriffen und dann gespannt wird. Das Halteelement 10-hier
im verriegelten Zustand dargestellt - ist an der Traverse
6 in einer vorderen Führung 12 und einer hinteren Führung
13 aufgenommen. Beide Führungen 12 und 13 begrenzen einen
Einführbereich 14. Die Führungen 12 und 13 sind an der
Traverse 6 durch eine Verschraubung 15 fixiert - eine andere
Befestigungsart wäre natürlich ebenso möglich. Neben der Verschraubung
15 und deren Mittellinie 22 sind voneinander beabstandete
einzelne Arretierungen - hier als Stifte 18 ausgeführt
- nebeneinander vorgesehen (siehe auch Fig. 2). Die
Stifte sind in Fig. 1 aus Gründen der Übersichtlichkeit lediglich
durch eine strichpunktierte Mittellinie 21 angedeutet.The
Das federnd ausgeführte Halteelement 10 kann in den Führungen
12 und 13 derart aufgenommen werden, daß es eine definierte
Einbaulage aufweist. Ein Torsionsstab 24, der einerseits in

Fig. 2 zeigt - vereinfacht dargestellt - den Verriegelungsvorgang eines Halteelementes an einer Traverse im Kanal eines Druckformzylinders.Fig. 2 shows - in simplified form - the locking process a holding element on a crossbar in the channel Printing form cylinder.
Ein Halteelement 10, dessen Seitenbereich mit einer Ausnehmung
16 versehen ist, nimmt im Kanal 2, dessen rückwärtige
Flanke 3 zu sehen ist, zunächst die Position 10.1 ein. In der
Position 10.1, der Einführungsposition, übergreift die mit
einer Rundung 23 versehene Ausnehmung 16 die Schraube 15 und
den daneben angeordneten Arretierungsstift 18. In Richtung
des vertikal nach unten weisenden Pfeiles wird das Halteelement
10 in die bis zur unteren Begrenzung eingeführte
Position 10.2 bewegt. In dieser Position 10.2 liegt die
Öffnung 17 der Ausnehmung 16 dem Stift 18 gegenüber. Durch
eine seitliche Verschiebung des Halteelementes 10 in Richtung
des horizontal, das heißt parallel zur Achse des
Druckformzylinders weisenden Pfeiles, umgreift die Öffnung 17
den Stift 18 und nimmt ihre verriegelte Position 10.3 ein.
Dabei tangiert der Rand der Ausnehmung 16 die Schraube 15
gerade nicht; die Öffnung 17 jedoch umschließt den
Arretierungsstift 18. In der Einbaulage der verriegelten
Position 10.3 stößt das zu verriegelnde Halteelement 10 jeweils an der Seitenkante 19 des
daneben liegenden Halteelementes 10 an. Die Ausnehmungen 16, die sowohl Schraube 15
als auch Arretierungsstifte 18 umgreifen, liegen an den Seiten der Halteelemente 10,
könnten jedoch auch in der Mitte der Halteelemente 10 vorgesehen sein. Die seitliche
Bewegung von der eingeführten Position 10.2 in die verriegelte Position 10.3 stellt eine
formschlüssige Verbindung zwischen den Arretierungen wie der Öffnung 17 und dem
Stift 18 her, die einen genauen Sitz angesichts der bei der Rotation des Druckformzylinders
auftretenden Fliehkräfte garantiert. Die Längskante 20 des jeweiligen Halteelementes 10
stößt nicht an der unteren Begrenzung des Spannkanals 2 an, sondern liegt im wesentlichen
zwischen Führungen 12 und 13 (siehe auch Fig. 1). Wie aus Fig. 2 weiterhin hervorgeht,
liegen die Mittellinien 21 und 22 von Schraube 15 und Arretierungsstift 18 geringfügig
übereinander, wie dies bereits in Fig. 1 angedeutet ist.A
Da mehrere Halteelemente 10 im Kanal 2 des Druckformzylinders 1 nebeneinanderliegend
angeordnet sind, welche untereinander fluchten, kann die Druckformhinterkante über deren
gesamte Breite ergriffen und die Druckform in definierter Lage am Umfang des
Druckformzylinders 1 fixiert werden.Since
Mittel zur Begrenzung der Auslenkung der Halteelemente 10 parallel zur Achse des
Druckformzylinders 1 sind ebenfalls vorgesehen, um die Entriegelung dieser
Halteelemente 10 an der Traverse 6 zu verhindern.Means for limiting the deflection of the
Wie in Fig. 3 gezeigt, weisen diese Mittel zur Begrenzung der Auslenkung ein biegsames
Plättchen 30 oder Federblatt auf,
das an einer der Seitenflächen des Druckformzylinders 1 in
Fluchtung mit dem Kanal 2 fixiert ist. Hierbei weist der
Druckformzylinder 1 eine Vertiefung 31 auf der Seite seiner
mit 32 bezeichneten Seitenfläche auf. Das biegsame Plättchen
30 ist in dieser Vertiefung mittels Schrauben 33, 33'
fixiert, die mit in der Vertiefung 31 angeordneten
Gewindelöchern zusammenwirken.As shown in Fig. 3, these means for limiting the deflection are
Wie man ebenfalls in Fig. 3 sieht, ist dieses biegsame Plättchen
30 am Druckformzylinder 1 derart angeordnet, daß die
Auslenkung der Halteelemente 10 parallel zur Achse des Druckformzylinders
1 in verriegelter Position begrenzt wird, was
in Fig. 3 mittels durchgezogener Linien der Halteelemente 10
an der Traverse 6 schematisiert ist.As can also be seen in Fig. 3, this is a
Weiterhin kann dieses biegsame Plättchen 30 derart gekrümmt
sein, daß dadurch das vertikale Einführen und die
Verriegelung der Halteelemente 10 an der Traverse 6 erlaubt
wird, wie mittels gestrichelter Linien in Fig. 3 gezeigt.Furthermore, this
Indem eine geeignete Länge für dieses biegsame Plättchen 30
gewählt wird, kann letzteres mit der Hand, das heißt ohne
jegliches Werkzeug gebogen werden. Die gesamte Montage oder
Demontage der Halteelemente 10 kann folglich ohne jegliches
Werkzeug erfolgen.By having a suitable length for this
In einer Variante kann dieses biegsame Plättchen durch ein
starres Plättchen als lösbarer Anschlag ersetzt werden, der
nach der Verriegelung der Halteelemente 10 an der Traverse 6
an einer der Seitenflächen des Druckformzylinders 1 auf
ähnliche Weise wie das biegsame Plättchen 30 fixierbar ist. In a variant, this flexible plate can be replaced by a
rigid plate can be replaced as a detachable stop, the

die beschriebenen und dargestellten Beispiele, was insbesondere
die Form der Mittel zur Begrenzung der Auslenkung der
Halteelemente 10 parallel zur Achse des Druckformzylinders 1
