Description

Die Erfindung betrifft eine Vorrichtung zum Spannen von Druckplatten für Druckmaschinen mit zwei in einer Zylinderausnehmung angeordneten, einen Endbereich der zu spannenden Druckplatte untergreifenden Spannleisten, deren Außenkonturen im gespannten Zustand eine der Zylinderkrümmung entsprechende Krümmung aufweisen und die jeweils durch eine an eine umgebogene Randklaue der zu spannenden Druckplatte angreifende Druckfläche begrenzt sind, wobei zwischen den Druckflächen der Spannleisten und den Spannleisten selbst ein elastischer Schlauch eingelegt ist, und wobei die Spannleisten mittels zweier in Vertiefungen angeordneter Exzenter in Spannrichtung der Druckplatte verstellbar sind.The invention relates to a device for tensioning printing plates for printing presses with two clamping bars arranged in a cylinder recess and under one end region of the tensioning plate to be tensioned, the outer contours of which, in the tensioned state, have a curvature corresponding to the cylinder curvature and which each have to be tensioned by a bent-over edge claw Pressure plate attacking pressure surface are limited, an elastic hose is inserted between the pressure surfaces of the clamping bars and the clamping bars themselves, and wherein the clamping bars are adjustable in the clamping direction of the pressure plate by means of two eccentrics arranged in recesses.

Des weiteren betrifft die Erfindung eine Vorrichtung zum Spannen von Druckplatten für Druckmaschinen mit zwei in einer Zylinderausnehmung seitlich verschiebbar angeordneten, einen Endbereich der zu spannenden Druckplatte untergreifenden Spannleisten, deren Außenkonturen im gespannten Zustand eine der Zylinderkrümmung entsprechende Krümmung aufweisen und die jeweils durch eine an eine umgebogene Randklaue der zu spannenden Druckplatte angreifende Druckfläche begrenzt sind, wobei zwischen den Druckflächen der Spannleisten und den Spannleisten selbst ein elastischer Schlauch eingelegt ist, und wobei die Spannleisten mittels zweier in Vertiefungen angeordneter Exzenter in Spannrichtung der Druckplatte verstellbar sind.Furthermore, the invention relates to a device for tensioning printing plates for printing presses with two clamping bars arranged laterally displaceably in a cylinder recess and under one end area of the tensioning plate to be tensioned, the outer contours of which, in the tensioned state, have a curvature corresponding to the cylinder curvature and which are each bent by a bent one Edge claw of the pressure surface engaging the pressure plate to be tensioned is limited, an elastic hose being inserted between the pressure surfaces of the tensioning bars and the tensioning bars themselves, and the tensioning bars being adjustable in the tensioning direction of the pressure plate by means of two eccentrics arranged in recesses.

Vorrichtungen dieser Art sind bekannt.Devices of this type are known.

So ist in der Patentanmeldung P 36 16 425.9 eine Vorrichtung zum Spannen von Druckplatten beschrieben, bei der die Spannleisten mittels zweier Hydraulikzylinder bewegt werden, um die Druckplatte auf den Zylinder zu spannen.Patent application P 36 16 425.9 describes a device for tensioning printing plates, in which the tensioning bars are moved by means of two hydraulic cylinders in order to tension the pressure plate on the cylinder.

Des weiteren sind in den Patentanmeldungen P 34 01 760.7 und P 37 02 032.3 Vorrichtungen zum Spannen von Druckplatten beschrieben, bei denen die jeweiligen Spannleisten mittels jeweils zweier Exzenter bewegt werden, um die Druckplatten jeweils auf die Zylinder zu spannen.Furthermore, devices for tensioning printing plates are described in patent applications P 34 01 760.7 and P 37 02 032.3, in which the respective tensioning bars are moved by means of two eccentrics in each case in order to tension the pressure plates on the cylinders.

Nachteilig ist bei den bekannten Vorrichtungen, daß die Herstellung derselben aufgrund notwendiger engster Fertigungstoleranzen aufwendig und damit kostenintensiv ist. Trotz der engen Fertigungstoleranzen bei der Herstellung der Vorrichtungen ist häufig ein exaktes Spannen der Druckplatten nicht gewährleistet, so daß die aufgespannten Druckplatten nicht exakt auf der Druckzylinderoberfläche anliegen, so daß während des Druckprozesses Schwingungen des Rakels auftreten, was wiederum die Qualität der Druckerzeugnisse beeinträchtigt.A disadvantage of the known devices is that the production of the same is complex and therefore cost-intensive due to the narrowest manufacturing tolerances required. Despite the tight manufacturing tolerances in the manufacture of the devices, an exact clamping of the printing plates is often not guaranteed, so that the clamped printing plates do not lie exactly on the surface of the printing cylinder, so that vibrations of the doctor blade occur during the printing process, which in turn adversely affects the quality of the printed products.

Es stellte sich daher die Aufgabe, Vorrichtungen herzustellen, bei denen die Druckplatte nach dem Spannen auf der gesamten Umfangsfläche des Zylinders angepreßt ist.It was therefore the task of producing devices in which the pressure plate is pressed on the entire circumferential surface of the cylinder after clamping.

Diese Aufgabe wird bei der ersten Vorrichtung dadurch gelöst, daß die Spannleisten während des Spannens der Druckplatten um eine zwischen den Spannleisten angeordneten Walze drehbar angeordnet sind.This object is achieved in the first device in that the clamping bars are rotatably arranged around a roller arranged between the clamping bars during tensioning of the pressure plates.

Des weiteren wird die Aufgabe bei der zweiten Vorrichtung dadurch gelöst, daß die Spannleisten während des Spannens der Druckplatten gegen eine mit der Zylinderausnehmung verbundenen Leiste mit jeweils prismenförmigen Außenkonturen anpreßbar sind.Furthermore, the object is achieved in the second device in that the clamping strips can be pressed against a strip connected to the cylinder recess, each with prism-shaped outer contours, during the clamping of the pressure plates.

Jeweils ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.

  • Figur 1 zeigt einen radialen Schnitt durch die erfindungsgemäße Vorrichtung mit einer Walze zwischen den Spannleisten, wobei die Druckplatte nicht gespannt ist.
  • Figur 2 zeigt denselben Schnitt, wobei jedoch die Druckplatte gespannt ist.
  • Figur 3 zeigt einen radialen Schnitt durch die erfindungsgemäße Vorrichtung mit einer Leiste zwischen den Spannleisten, wobei die Druckplatte nicht gespannt ist,
  • Figur 4 zeigt denselben Schnitt, wobei jedoch die Druckplatte gespannt ist.
One embodiment of the invention is shown in the drawing and is described in more detail below.
  • Figure 1 shows a radial section through the device according to the invention with a roller between the clamping bars, wherein the pressure plate is not tensioned.
  • Figure 2 shows the same section, but the pressure plate is tensioned.
  • FIG. 3 shows a radial section through the device according to the invention with a bar between the clamping bars, the pressure plate not being tensioned,
  • Figure 4 shows the same section, but the pressure plate is tensioned.

Die Vorrichtung gemäß den Figuren 1 und 2 besteht im wesentlichen aus den zwei in einer Zylinderausnehmung 1 angeordneten, bezüglich einer Radialebene symmetrisch ausgebildeten Spannleisten 2, bei denen die radial äußere Stirnseite im gespannten Zustand eine der Zylinderkrümmung entsprechende Krümmung aufweist. Die einander zugewandten, radial äußeren Kanten der beiden Spannleisten sind als Schnabelkanten mit gegenüber der Umfangskontur spitzwinklig abgewinkelten Spannflächen 3 ausgebildet, die einen nach außen konvergierenden Spannkanal 4 begrenzen. Im ungespannten Zustand der Spannleisten grenzen dieselben mit den voneinander abgewandten Seiten teilweise gegen jeweils ebenfalls in der Zylinderausnehmung eingelegte Einsatzstücke 5. Diese Einsatzstücke, deren Außenkonturen ebenfalls der Zylinderkontur entsprechen, sind mit dem Zylinder verschraubt. Zwischen den einander zugewandten Seiten der Spannflächen und einer - erfindungsgemäß nicht relevanten - mit dem Zylinder verschraubten Unterlageplatte 6 ist eine Walze 8 angeordnet. Zwischen den Spannflächen 3 der Spannleisten 2 und den Spannleisten selbst ist ein elastischer Schlauch 7 - gefüllt mit Spaltverschlußmasse - angeordnet, der auf seiner gesamten Länge - entspricht der Zylinderlänge - mit einer oder mehreren Öffnungen in Richtung der zu spannenden Druckplatte 9 versehen ist. In Vertiefungen der Einsatzstücke sind jeweils in der gesamten Länge der Einsatzstücke zwei Exzenter 11 eingelegt. Diese Exzenter stützen sich bei gespannten Spannleisten an ihrer einen Seite über die Einsatzstücke an der zylinderfesten Wandung ab.The device according to FIGS. 1 and 2 essentially consists of the two clamping strips 2 arranged in a cylinder recess 1 and symmetrically formed with respect to a radial plane, in which the radially outer end face has a curvature corresponding to the cylinder curvature in the tensioned state. The mutually facing, radially outer edges of the two clamping strips are designed as beak edges with clamping surfaces 3 which are angled at an acute angle with respect to the circumferential contour and which delimit a clamping channel 4 which converges towards the outside. In the untensioned state of the tensioning strips, they partially border with the sides facing away from one another, in each case also against insert pieces 5 which are also inserted in the cylinder recess. These insert pieces, whose outer contours also correspond to the cylinder contour, are screwed to the cylinder. A roller 8 is arranged between the mutually facing sides of the clamping surfaces and a base plate 6 which is not relevant to the invention and which is screwed to the cylinder. Between the clamping surfaces 3 of the clamping strips 2 and the clamping strips themselves there is an elastic hose 7 - filled with gap sealing compound - which is provided over its entire length - corresponding to the cylinder length - with one or more openings in the direction of the pressure plate 9 to be clamped. Two eccentrics 11 are inserted in the recesses of the inserts over the entire length of the inserts. In the case of tensioned clamping bars, these eccentrics are supported on one side by the insert pieces on the cylinder-fixed wall.

Die aufzuspannende Druckplatte 9 ist im Bereich ihrer Enden mit spitzwinklig angewinkelten Randklauen 10 versehen, die die Spannflächen übergreifen.The pressure plate 9 to be clamped is provided in the region of its ends with edge claws 10 which are angled at an acute angle and overlap the clamping surfaces.

Um nun die Druckplatte 9 auf den Zylinder 1 zu spannen, werden die beiden Exzenter 11 jeweils mittels eines Schlüssels um 90°C gedreht, hierbei drehen sich die beiden Spannleisten selbstzentrierend um die Walze.In order to clamp the pressure plate 9 on the cylinder 1, the two eccentrics 11 are each rotated by 90 ° C. using a key, in this case the two clamping strips rotate self-centering around the roller.

Beim gleichzeitigen Anpressen der Randklauen 10 an die jeweils zugeordnete Spannfläche 3, ebenfalls ausgelöst durch Drehen der beiden Exzenter 11 um 90°C, wird der im Spannkanal 4 angeordnete elastische Schlauch 7, gegen die Außenkontur des Zylinders gepreßt wird. Oberhalb der Außenkontur im Spaltbereich befindet sich ein Formstück 12, das die obere Begrenzung für den Spaltverschluß bildet. Abschließend wird Spaltverschlußmasse in den Schlauch gedrückt und durch eine Öffnung des Schlauches gegen das Formstück gepreßt. Nach dem Aushärten der Spaltverschlußmasse gleicht die Außenkontur des gefüllten Spaltes der Außenkontur des Zylinders.When the edge claws 10 are pressed simultaneously onto the respectively assigned clamping surface 3, also triggered by rotating the two eccentrics 11 by 90 ° C., the elastic hose 7 arranged in the clamping channel 4 is pressed against the outer contour of the cylinder. Above the outer contour in the gap area is a shaped piece 12, which forms the upper limit for the gap closure. Finally, the gap sealing compound is pressed into the hose and pressed against the fitting through an opening in the hose. After the gap sealing compound has hardened, the outer contour of the filled gap resembles the outer contour of the cylinder.

Die Vorrichtung gemäß den Figuren 3 und 4 entspricht grundsätzlich der oben beschriebenen Vorrichtung. Als entscheidender Unterschied ist - anstelle der Walze - eine mit Schrauben 6 in den Zylinder 1 eingeschraubte Leiste 8 mit prismenförmigen Außenkonturen angebracht. Beim Drehen der Exzenter 11 um 90°C werden die beiden Spannleisten 2 selbstzentrierend gegen die prismenförmigen Außenkanten der Leiste gespreßt.The device according to FIGS. 3 and 4 basically corresponds to the device described above. As a decisive difference, a bar 8 with prism-shaped outer contours is screwed into the cylinder 1 with screws 6 instead of the roller. When the eccentric 11 is turned by 90 ° C., the two clamping strips 2 are pressed against the prism-shaped outer edges of the strip in a self-centering manner.
