Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen einer Bespannung auf einem Zylinder einer Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for fastening a clothing on a cylinder of a rotary printing press according to the preamble of claim 1.

Aus der DE 197 03 290 A1 der Anmelderin ist bereits eine Vorrichtung zum Befestigen einer Bespannung auf einem Druckzylinder einer Rotationsdruckmaschine bekannt. Bei dieser bekannten Vorrichtung wird ein Klemmkörper innerhalb eines achsparallelen Kanals des Zylinderkörpers durch Druckfedern radial nach außen auf die Kanalflächen gedrückt, um eine zwischen den Kanalflächen und dem Klemmkörper befindliche Bespannung zu fixieren. Zum Aufspannen und Abspannen der Bespannung wird der Klemmkörper durch an seinen äußeren Enden befindliche Stellschrauben radial zum Zylinderinnern verstellt. In dieser Aufspann- und Abspannposition bewirken die Druckfedern eine Durchbiegung der Klemmleiste zum Zylinder-äußeren zwischen den endständigen Stellschrauben.From the DE 197 03 290 A1 The applicant is already known a device for attaching a fabric to a printing cylinder of a rotary printing press. In this known device, a clamping body is pressed within a paraxial channel of the cylinder body by compression springs radially outward on the channel surfaces to fix a located between the channel surfaces and the clamping body covering. For clamping and unclamping the clothing of the clamping body is adjusted by located at its outer ends screws radially to the cylinder interior. In this clamping and bracing position, the compression springs cause a deflection of the terminal block to the cylinder-outer between the terminal screws.

Die US 6 378 430 B1 offenbart ebenfalls eine gattungsgemäße Vorrichtung zur Befestigung einer Bespannung auf einem Druckzylinder einer Rotationsdruckmaschine.The US Pat. No. 6,378,430 B1 also discloses a generic device for fixing a fabric on a printing cylinder of a rotary printing press.

Gerade bei schlanken Zylindern, wie zum Beispiel einfachrunden und mehreren Seiten breiten Druckzylindern, ist die Größe beziehungsweise der Durchmesser der Kanalbohrung begrenzt. Aufgrund des limitierten Kanaldurchmessers ist entsprechend die Abmessung der Klemmleiste und damit einhergehend deren Steifigkeit begrenzt. Wird zum Aufspannen oder zum Abspannen der Bespannung der Klemmkörper durch an seinen äußeren Enden befindliche Stellschrauben radial zum Zylinderinnern verstellt, so kann der Bauch der durchgebogenen Klemmleisten im Zylindermittelbereich so nahe an die Kanalwandung ragen, so dass kein Lösen beziehungsweise Einführen der Bespannung erfolgen kann.Especially with slender cylinders, such as single-round and multi-page wide pressure cylinders, the size or the diameter of the channel bore is limited. Due to the limited channel diameter, the dimension of the terminal block and, consequently, its rigidity are limited accordingly. If the clamp body is clamped radially to the interior of the cylinder by means of adjusting screws located at its outer ends for clamping or clamping the clothing, the belly of the bent-over clamping strips in the cylinder center region can protrude so close to the duct wall that no loosening or insertion of the clothing can take place.

Die Erfinder haben sich daher die Aufgabe gestellt, eine Vorrichtung zum Befestigen einer Bespannung auf einem Zylinder einer Rotationsdruckmaschine so zu verbessern, dass eine Durchbiegung der Klemmleiste beim Lösen der Klemmung vermieden wird.The inventors have therefore set themselves the task to improve a device for attaching a fabric to a cylinder of a rotary printing press so that a deflection of the terminal strip is avoided when loosening the clamping.

Diese Aufgabe wird durch eine Vorrichtung zum Befestigen einer Bespannung auf einem Zylinder einer Rotationsdruckmaschine gemäß Anspruch 1 gelöst.This object is achieved by a device for fastening a clothing on a cylinder of a rotary printing press according to claim 1.

Die Erfinder haben erkannt, dass es möglich ist die Durchbiegung der Klemmleiste beim Aufspannen oder beim Abspannen einer Bespannung zu verhindern, wenn im Spannkanal zusätzlich zur Klemmleiste Stützelemente derart angeordnet werden, so dass die Stützelemente als mechanische Barriere für die Durchbiegung der Klemmleiste fungieren und gleichzeitig durch die Stützelemente eine Ableitung der aus der Durchbiegung resultierenden Kraft auf die Kanalinnenwandung bewirkt wird. Aus den gewonnenen Erkenntnissen heraus schlagen die Erfinder vor, eine Vorrichtung zum Befestigen einer Bespannung auf einem Zylinder einer Rotationsdruckmaschine mit mindestens einem achsparallelen Kanal im Zylinder, der einen Schlitz zum Einschieben und Herausziehen der Enden einer Bespannung ausbildet und einem im Kanal angeordneten Klemmkörper, der mittels mehrerer Druckfedern zum Befestigen der Bespannung radial in Richtung des Schlitzes gedrückt wird, wobei an den Enden des Zylinders Stellelemente angeordnet sind, über die der Klemmkörper radial verschiebbar geführt ist, um ein Einschieben und Herausziehen der Enden der Bespannung zu ermöglichen, dahingehend zu verbessern, dass innerhalb des Kanals neben dem Klemmkörper mindestens ein Stützelement angeordnet ist, das in mindestens eine Ausnehmung im Klemmkörper eingreift, wobei durch eine Bewegung der Stellelemente eine Relativbewegung zwischen Stützelement und Klemmkörper bewirkt wird und das Fixierelement eine axiale Verschiebung des Klemmkörpers verhindert, aber eine radiale Verschiebung des Klemmkörpers ermöglicht und das mindestens eine Fixierelement in einem Langloch verschiebbar angeordnet ist.The inventors have recognized that it is possible to prevent the deflection of the terminal strip during clamping or when clamping a stringing, if in the chip channel in addition to the terminal block support elements are arranged so that the support elements act as a mechanical barrier for the deflection of the terminal block and at the same time the support elements a derivative of the force resulting from the deflection force is effected on the channel inner wall. From the knowledge gained, the inventors propose a device for fastening a clothing on a cylinder of a rotary printing machine with at least one axially parallel channel in the cylinder, which forms a slot for insertion and withdrawal of the ends of a fabric and a clamping body arranged in the channel, by means of a plurality of compression springs for fastening the clothing is pressed radially in the direction of the slot, wherein at the ends of the cylinder actuating elements are arranged, via which the clamping body is guided radially displaceable to allow insertion and withdrawal of the ends of the fabric, to improve that at least one support element is arranged within the channel next to the clamping body, which engages in at least one recess in the clamping body, wherein a relative movement between the support member and clamping body is effected by a movement of the adjusting elements and the fixing element is an axial e displacement of the clamp body prevents, but allows a radial displacement of the clamp body and the at least one fixing element is slidably disposed in a slot.

Wird bei dieser Ausführung der Vorrichtung zum Befestigen einer Bespannung auf einem Zylinder das Stützelement durch das Stellelement in Richtung der Kanalbohrung verschoben, so führt diese Verstellbewegung im Langloch zu einer Relativbewegung zwischen Klemmkörper und Stützelement in radialer Richtung der Kanalbohrung. Das Stützelement wird an die Kanalbohrungswandung somit ge drückt und führt zum Absenken des Klemmkörpers aus der Fixierstellung der Bespannung. Durch das Abstützen des Stützelementes in der Kanalbohrung wird damit das Durchbiegen des Klemmkörpers vorteilhaft verhindert.If, in this embodiment of the device for fastening a clothing on a cylinder, the support element is displaced by the adjusting element in the direction of the channel bore, this adjustment movement in the slot results in a relative movement between the clamping body and the support element in the radial direction of the channel bore. The support element is thus pressed against the channel bore wall ge and leads to lowering of the clamp body from the fixing position of the fabric. By supporting the support element in the channel bore so that the bending of the clamp body is advantageously prevented.

Nachfolgend wird die hier vorliegende Erfindung unter Bezugnahme auf die Figuren 1 bis 4 beschrieben.Hereinafter, the present invention will be described with reference to FIGS FIGS. 1 to 4 described.

Die Figur 1 zeigt in einer Schnittansicht senkrecht durch die Zylinderrotationsachse einen Teilausschnitt eines Zylinders 2 mit neuer Spannvorrichtung. Beim Zylinder 2 kann es sich sowohl um einen Form- als auch um einen Übertragungszylinder handeln, der als Aufzug beziehungsweise als Bespannung 1 ein oder mehrere Druckplatten oder ein oder mehrere Gummitücher an der Zylinderoberfläche trägt. Um die Enden der Bespannung 1 am Zylinder 2 befestigen zu können, ist ein axial verlaufender Spannkanal 3 im Zylinder 2 eingelassen, der an der Zylinderoberfläche einen Schlitz 4 ausbildet in den beziehungsweise aus dem die Bespannung 1 ein-/ausgeführt wird. Über nicht dargestellte Federelemente können die Enden der Bespannung 1 zwischen Kanalinnenwandung und Klemmkörper 5 geklemmt werden. Der Klemmkörper 5 ist in radialer Richtung 11 zum Auf- beziehungsweise Abspannen der Bespannung 1 beweglich gelagert. Durch ein Stellelement 7, hier ein Stift oder ein Gewindestift, der parallel zur Zylinderrotationsachse verschiebbar ist, kann der Klemmkörper 5 in Kanalrichtung verschoben werden, wobei sich eine Relativbewegung des Klemmkörpers 5 bezüglich der nicht dargestellten Stützelemente in Richtung 11 ergibt und ein Fixierstift 13, der in einem Langloch beweglich gelagert ist bewirkt, dass der Klemmkörper 5 sich lediglich in radialer Zylinderrichtung 11 verschieben lässt.The FIG. 1 shows in a sectional view perpendicular through the cylinder axis of rotation a partial section of a cylinder 2 with a new clamping device. The cylinder 2 can be both a forming cylinder and a transfer cylinder, which carries one or more printing plates or one or more blankets on the cylinder surface as the elevator or covering 1. In order to attach the ends of the fabric 1 on the cylinder 2, an axially extending clamping channel 3 is inserted in the cylinder 2, which forms a slot 4 in the or from which the fabric 1 is on / executed on the cylinder surface. Not shown spring elements, the ends of the fabric 1 between channel inner wall and clamp body 5 can be clamped. The clamping body 5 is movably mounted in the radial direction 11 for mounting or unclamping the covering 1. By an adjusting element 7, here a pin or a threaded pin which is displaceable parallel to the cylinder rotation axis, the clamping body 5 can be moved in the channel direction, with a relative movement of the clamping body 5 with respect to the supporting elements, not shown in direction 11 results and a fixing pin 13, the movably mounted in a slot causes the clamping body 5 can be moved only in the radial direction of the cylinder 11.

Die Figur 1 a zeigt einen Schnitt durch den Fixierstift 13 und den Klemmkörper 5. Der Fixierstift 13 ist in einem Langloch 14 gelagert, wodurch nur eine radiale Bewegung 11 des Klemmkörpers 5 ermöglicht wird und ein axiales Verschieben in Richtung der Kanalbohrung verhindert wird.The FIG. 1 a shows a section through the fixing pin 13 and the clamping body 5. The fixing pin 13 is mounted in a slot 14, whereby only a radial movement 11 of the clamping body 5 is made possible and an axial displacement in the direction of the channel bore is prevented.

Die Figur 2 zeigt eine Schnittansicht durch den Spannkanal 3 und eine weitere Ausführung der neuen Spannvorrichtung. Bei der Bespannung 1 handelt es sich um ein Drucktuch, welches sich auf einer Trägerplatte befindet. Die beiden Enden der Trägerplatte werden mit dem Klemmkörper 5 an die Kanalinnenwandung ge drückt, wodurch das Drucktuch auf dem Umfang des Zylinders 2 aufgespannt wird. Dabei wird der Klemmkörper 5 vom Boden des Spannkanals 3 mittels Druckfedern 6 in Richtung Schlitz 4 gedrückt. Der Klemmkörper 5 weist in Richtung des Schlitzes 4 zwei konisch verlaufende Flanken auf, wobei die beiden Enden der Trägerplatte in Figur 2 an der oberen Flanke geklemmt werden. Im Spannkanal 3 sind oberhalb und unterhalb des Klemmkörpers 5 Stützelemente 8 angeordnet, die über nicht dargestellte Verbindungselemente und Ausnehmungen im Klemmkörper 5 miteinander verbunden sind. Wird der Klemmkörper 5 durch ein nicht dargestelltes Stellelement in Richtung der Kanalbohrung verschoben, so führt diese Verstellbewegung im Langloch zu einer Relativbewegung zwischen Klemmkörper 5 und Stützelement in radialer Richtung 11 der Kanalbohrung. Das Stützelement wird an die Kanalbohrungswandung gedrückt und führt zum Absenken des Klemmkörpers 5 aus der Fixierstellung der Bespannung 1. Durch das Abstützen des Stützelementes 8 in der Kanalbohrung wird das Durchbiegen des Klemmkörpers 5 verhindert.The FIG. 2 shows a sectional view through the clamping channel 3 and another embodiment of the new clamping device. The fabric 1 is a blanket, which is located on a support plate. The two ends of the support plate are pressed with the clamping body 5 ge to the channel inner wall, whereby the blanket is clamped on the circumference of the cylinder 2. In this case, the clamping body 5 is pressed from the bottom of the clamping channel 3 by means of compression springs 6 in the direction of slot 4. The clamping body 5 points in the direction of the slot 4 two conically extending flanks, wherein the two ends of the support plate in FIG. 2 be clamped on the upper flank. In the clamping channel 3 5 support elements 8 are arranged above and below the clamping body, which are connected via not shown connecting elements and recesses in the clamping body 5 with each other. If the clamping body 5 is displaced by an adjusting element, not shown, in the direction of the channel bore, this adjusting movement in the slot results in a relative movement between the clamping body 5 and the supporting element in the radial direction 11 of the channel bore. The support element is pressed against the channel bore wall and leads to the lowering of the clamping body 5 from the fixing position of the fabric 1. By supporting the support member 8 in the channel bore, the bending of the clamp body 5 is prevented.

Die Figur 3 zeigt in einer Draufsicht einen Teilabschnitt eines Klemmkörpers 5 in Längsrichtung des Spannkanals 3. Links in Figur 3 ist ein bolzenförmiges Stellelement 7 angeordnet, welches über eine Gewindeführung verfügt und sich in Richtung 12, hier parallel zur Zylinderachse, verfahren lässt. Der Klemmkörper 5 weist ein Langloch 9 auf, welches eine schräge Neigung besitzt. Durch das Langloch 9 werden die Stützelemente (nur teilweise abgebildet) mittels eines Bolzens 10 miteinander verbunden. Wird nun das Stellelement 7 nach rechts bewegt, so werden die Stützelemente 8 an die Kanalbohrungswandung gedrückt und der Klemmkörper 5 wird um den Verstellhub h radial nach unten abgesenkt, so dass der Schlitz am Zylinder zum Aufspannen oder Abspannen der Bespannung frei gegeben wird. Im abgesenkten Zustand wäre der Bolzen 10 an der oberen Position des Langloches 9 (gestrichelt dargestellt). Über den in Figur 1a beschriebenen Fixierstift 13 wird nur eine radiale Bewegung 11 des Klemmkörpers 5 ermöglicht, während die Stützelemente 8 sich axial innerhalb der Kanalbohrung verschieben lassen.The FIG. 3 shows in a plan view a partial section of a clamping body 5 in the longitudinal direction of the clamping channel 3. Left in FIG. 3 a bolt-shaped adjusting element 7 is arranged, which has a thread guide and can be in the direction 12, here parallel to the cylinder axis, moved. The clamping body 5 has a slot 9, which has an oblique inclination. Through the slot 9, the support elements (only partially shown) connected by a bolt 10 with each other. Now, if the actuator 7 is moved to the right, the support elements 8 are pressed against the Kanalbohrungswandung and the clamping body 5 is lowered by the Verstellhub radially downwards, so that the slot on the cylinder for clamping or clamping the fabric is released. In the lowered state, the bolt 10 would be at the upper position of the slot 9 (shown in phantom). About the in FIG. 1a described fixing pin 13 is only a radial movement 11 of the clamping body 5 allows while the support elements 8 can be moved axially within the channel bore.

Die Figur 4 zeigt eine Schnittansicht durch einen Klemmkörper 5 mit Stützelementen 8 und Bolzen 10 durch die Ebene des Langlochs 9.The FIG. 4 shows a sectional view through a clamping body 5 with support elements 8 and bolts 10 through the plane of the slot 9th
