Abstract

The purpose of a device for clamping and adjusting flexible printing plates (36) on plate cylinders (1) of rotary printing presses is to achieve automatic clamping and partial adjustment of the printing plates (36) while keeping both the channel width and the transmission losses low. The invention attains this purpose in that a pressure rail (13) can be moved radially by adjusters (19, 22, 24, 26, 28) that, via inclines (17, 18) and a secant intersecting the cylinder channel at an angle β of about 90 °C, trigger the clamping and adjustment movement of the plate clamping rail (33).

Description

Die Erfindung betrifft eine Einrichtung zum Spannen und Justieren von biegsamen Druckplatten auf Plattenzylindern von Rotationsdruckmaschinen entsprechend dem Oberbegriff der Patentansprüche 1 und 2.The invention relates to a device for tensioning and adjusting flexible printing plates on plate cylinders of rotary printing presses according to the preamble of claims 1 and 2.

Bei Bogenrotationsdruckmaschinen ist man u. a. auch bestrebt, die Vorbereitungs- und Hilfszeiten zu verkürzen, bei gleichzeitiger Erhöhung der Druckqualität. Dabei ist es wichtig, die biegsamen Druckplatten in kurzer Zeit einzuspannen und zu justieren.In sheet-fed rotary printing machines one is u. a. also strives to reduce preparation and support times while increasing print quality. It is important to clamp and adjust the flexible printing plates in a short time.

Entsprechend der DE 29 35 699 A1 ist eine Vorrichtung zum registerhaltigen Spannen von Druckplatten in Druckmaschinen bekannt, bei welcher eine Spannschiene spiegelbildlich angeordnete Keilebenen aufweist. Gegen diese Keilebenen sind Kulissen-Keilebenen von auf einer Stellspindel mit gegenläufigem Gewinde angeordneten Kulissenblöcken anstellbar, so daß die Spannschiene parallel zur Zylinderachse gespannt wird.According to DE 29 35 699 A1, a device for register-holding clamping of printing plates in printing presses is known, in which a clamping rail has wedge planes arranged in mirror image. Link wedge planes of link blocks arranged on an adjusting spindle with opposite thread can be set against these wedge planes, so that the tensioning rail is tensioned parallel to the cylinder axis.

Nachteilig bei dieser Vorrichtung ist es, daß der Kanal allein schon zur Aufnahme dieser in Plattenspannrichtung wirksamen Stellorgane eine bestimmte Breite aufweisen muß.A disadvantage of this device is that the channel just to accommodate these actuators effective in the plate clamping direction must have a certain width.

Ein weiterer Nachteil ist, daß eine Vielzahl von Hebelanordnungen zum Einsatz kommen und ein Justieren der Druckplatte auf Grund einer Parallelführung von Scherenarmen nicht möglich ist.Another disadvantage is that a large number of lever arrangements are used and an adjustment of the pressure plate is not possible due to the parallel guidance of scissor arms.

Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zum fernbetätigten Spannen und ferbetätigten, auch einteiligen Justieren von biegsamen Druckplatten auf Plattenzylindern von Bogenrotationsdruckmaschinen zu schaffen, bei welcher der Platzbedarf für die Einrichtung zur Erzeugung der Kraft für die Spannbewegung gering ist.The invention has for its object to provide a device for remote clamping and remotely actuated, also one-piece adjustment of flexible printing plates on plate cylinders of sheet-fed rotary printing presses, in which the space required for the device for generating the force for the clamping movement is small.

Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen der Patentansprüche 1 und 2 gelöst. In den Unteransprüchen sind zweckmäßige Ausgestaltungen der Erfindung enthalten.This object is achieved by the characterizing part of claims 1 and 2. Appropriate embodiments of the invention are contained in the subclaims.

Durch die Erfindung werden insbesondere folgende Vorteile erzielt. Durch die Anordnung von insbesondere zwei Antrieben ist es möglich geworden, durch die einfache lineare Auslenkung eines Druckplattenendes die Druckplatte zu spannen und zu justieren. Auch ein Verschwenken bzw. Diagonalverstellen der Druckplatte ist möglich, wenn die zweite Schnellspanneinrichtung, zum Festhalten und Spannen der Druckplattenvorderkante mit einem erfindungsgemäßen Antrieb versehen ist. Dabei treten keine Biegemomente in Bauteilen auf, die eine Überdimensionierung erfordern und somit auch einen hohen Platzbedarf haben. Die Kräfte werden über die Keilflächen mittels Druck übertragen. Die Krafteinleitungspunkte befinden sich in der Nähe des Umfangs des Plattenzylinders, wodurch größere Hebelübersetzungen vermieden werden.The following advantages are achieved in particular by the invention. The arrangement of two drives in particular has made it possible to tension and adjust the pressure plate by simply linearly deflecting a pressure plate end. A pivoting or diagonal adjustment of the pressure plate is also possible if the second quick release device for Holding and tensioning the pressure plate leading edge is provided with a drive according to the invention. There are no bending moments in components that require overdimensioning and thus also take up a lot of space. The forces are transferred via the wedge surfaces using pressure. The force introduction points are close to the circumference of the plate cylinder, which prevents larger lever ratios.

Die Erfindung soll nachstehend an mehreren Ausführungsbeispielen erläutert werden. Die zugehörigen Zeichnungen zeigen.

Gemäß Fig. 1 ist ein Längsschnitt durch den Kanal des Plattenzylinders mit der erfindungsgemäßen Einrichtung gezeigt. Der Schnitt verläuft entlang der Linie C-D nach Fig. 4. Die dazugehörige Fig. 1 zeigt diesen Schnitt. Die gezeigten Teile nach Fig. 4 sind je Zylinder in spiegelbildlicher Form zweimal vorhanden. Dies wird durch eine senkrecht verlaufende Mittellinie 37 verdeutlicht. Der Plattenzylinder 1 weist an seiner Oberfläche einen axial verlaufenden Kanal 2; 3 auf, welcher jeweils in seiner Länge von den Stirnseiten 4; 6 des Plattenzylinders 1 und Sockeln 7; 8 begrenzt wird. Zwischen den Sockeln 7; 8 befindet sich eine Kanalgrube 9, welche gegenüber den Kanälen 2; 3 tiefer gelegen ist, um den Antrieb der Einrichtung aufzunehmen. Der Sockel 7 endet in einer in Richtung Kanalgrube 9 verlaufenden Schräge 11, während eine Fläche 12 des Sockels 8 waagerecht verläuft. Eine sich in axialer Richtung erstreckende Druckleiste 13 ist in einer Ausnehmung zwischen der oberen Kanalseitenwand 14 und der unteren Kanalseitenwand 16 angeordnet. Die Druckleiste 13 besitzt auf der in Richtung Kanalgrube 9 weisenden Seite zwei keilförmige Absätze 17; 18, welche mit der Schräge 11 des Sockels 7 direkt und mit der waagerechten Fläche 12 des Sockels 8 indirekt in Wirkverbindung stehen. Die Schräge 11 verläuft in einem Winkel α zur Waagerechten, der dem Winkel α des keilförmigen Absatzes 17 entspricht. Der Betrag des Winkels kann zwischen 5o und 30o liegen.1 shows a longitudinal section through the channel of the plate cylinder with the device according to the invention. The section runs along the line CD according to FIG. 4. The associated FIG. 1 shows this section. The parts shown in FIG. 4 are present twice in mirror-image form per cylinder. This is illustrated by a perpendicular center line 37. The plate cylinder 1 has an axially extending channel 2 on its surface; 3, which in each case in its length from the end faces 4; 6 of the plate cylinder 1 and bases 7; 8 is limited. Between the bases 7; 8 there is a channel pit 9, which is opposite the channels 2; 3 is located lower to accommodate the drive of the device. The base 7 ends in a slope 11 running in the direction of the channel pit 9, while a surface 12 of the base 8 runs horizontally. A pressure bar 13 extending in the axial direction is arranged in a recess between the upper channel side wall 14 and the lower channel side wall 16. The pressure bar 13 has on the side facing the channel pit 9 two wedge-shaped shoulders 17; 18, which are in direct connection with the slope 11 of the base 7 and indirectly with the horizontal surface 12 of the base 8. The slope 11 extends at an angle α to the horizontal, which corresponds to the angle α of the wedge-shaped shoulder 17. The amount of the angle can be between 5 o and 30 o .

Zwischen der waagerecht verlaufenden Fläche 12 des Sockels 8 und der an der Druckleiste 13 befindlichen schiefen Ebene 18 befindet sich ein einseitig ausgebildeter erster Keil 19.Between the horizontally extending surface 12 of the base 8 and the inclined plane 18 located on the pressure bar 13 there is a first wedge 19 formed on one side.

An den Flächen, die miteinander in Wirkverbindung stehen, können zur Verminderung der Reibung Flachnadelkäfige 21 angeordnet sein. Der Winkel α des keilförmigen Absatzes 18 entspricht dabei dem Winkel α des Keiles 19. Der Keil 19 besitzt in axialer Richtung eine Gewindebohrung und ist auf einer Gewindespindel 22 in achsparalleler Richtung E bewegbar, da sich die Gewindespindel 22 einerseits über einen Anschlag 23 an der Stirnseite 6 des Plattenzylinders 1 abstützt und andererseits drehfest mit einem Zahnrad 24 verbunden ist. Das Zahnrad 24 kämmt mit einem Zahnrad 26, welches wiederum drehfest über eine Welle 27 mit einem Motor 28 in Verbindung steht. Der Motor 28 ist auf der Kanalgrube 9 befestigt. Die Lagerung der Zahnräder 24; 26 wurde zur Vereinfachung der Zeichnung nicht dargestellt. Die Druckleiste 13 besitzt auf ihrer von der Kanalseitenwand 16 abgewandten Seite, etwa vom letzten Drittel ihres kanalfernen Endes ausgehend, eine in Richtung obere Kanalseitenwand 14 verlaufende Abschrägung 29, welche mit einem Vorsprung 31, z. B. eines kalottenförmigen Endes 31 oder einer Gegenschräge einer Stellschraube 32 in Wirkverbindung steht. Auf der Spannschiene 33 ist eine bekannte Klemmschiene 34 einer Schnellspanneinrichtung angeordnet. Zwischen Spannschiene 33 und Klemmschiene 34 ist eine Druckplatte 36 festgehalten. Die Spannschiene 33 ist mit ihrer in Richtung Mittellinie 37 weisenden Seite mittels Federn 35 an einer parallel zur Mittellinie 37 verlaufenden Trennwand 39 abgestützt. Die Mittellinie 37 verläuft durch die Rotationsachse 35 des Plattenzylinders 1.Flat needle cages 21 can be arranged on the surfaces which are operatively connected to one another to reduce the friction. The angle α of the wedge-shaped shoulder 18 corresponds to the angle α of the wedge 19. The wedge 19 has a threaded bore in the axial direction and can be moved on a threaded spindle 22 in the axis-parallel direction E, since the threaded spindle 22 on the one hand has a stop 23 on the end face 6 of the plate cylinder 1 is supported and on the other hand is rotatably connected to a gear 24. The gear 24 meshes with a gear 26, which in turn is connected to a motor 28 in a rotationally fixed manner via a shaft 27. The motor 28 is attached to the channel pit 9. The storage of the gears 24; 26 has not been shown to simplify the drawing. The pressure bar 13 has on its side facing away from the channel side wall 16, starting approximately from the last third of its end remote from the channel, a bevel 29 which runs in the direction of the upper channel side wall 14 and which has a projection 31, for. B. a dome-shaped end 31 or a counter slope of an adjusting screw 32 is operatively connected. A known clamping rail 34 of a quick-action clamping device is arranged on the clamping rail 33. Between tensioning rail 33 and clamping rail 34 is one Pressure plate 36 held. The tensioning rail 33 is supported with its side pointing in the direction of the center line 37 by means of springs 35 on a partition 39 running parallel to the center line 37. The center line 37 runs through the axis of rotation 35 of the plate cylinder 1.

Die Einrichtung nach Fig. 1 und 4 arbeitet wie folgt. Eine Druckplatte 36 wird in einer nicht in Fig. 4 dargestellten, jedoch jenseits der Mittellinie 37 spiegelbildlich angeordneten Klemmvorrichtung festgehalten, auf die Mantelfläche des Plattenzylinders 1 aufgebracht und zwischen der Spannschiene 33 und der Klemmschiene 34 durch einen nicht näher beschriebenen, jedoch z. B. nach DE 36 04 071 C2 bekannten Mechanismus festgeklemmt. Der Motor 28, der als Gleichstrommotor mit Drehmomentbegrenzung und Positioniereinrichtung ausgeführt ist, treibt über das Getriebe 27; 26; 24; 22; 23; 6 den mit Innengewinde versehenen Keil 19 an, welcher je nach der Drehrichtung des Motors 28 in achsparalleler Richtung E bewegbar ist. Infolge der Wirkverbindung, die sich aus dem Keil 19 und dem sich an der Druckleiste 13 befindlichen keilförmigen Absatz 18 sowie der Wirkverbindung, die sich aus der Schräge 11 des Sockels 7 und keilförmigen Absatz 17 ergibt, erfährt die Druckleiste 13 eine Auf- und Abbewegung in radialer oder annähernd radialer Richtung F, maximal um einen Weg h. Die Druckleiste 13 wird über ihre Abschrägung 29 gegen das kalottenförmige Ende 31 der Stellschraube 32 gedrückt. Hierdurch erfolgt eine Bewegung der Spannschiene 33 in Richtung einer Sekante 45 zum Plattenzylinder 1, die den Zylinderkanal 2; 3 schneidet. Die Sekante 45 verläuft in einem Winkel β zur radial bewegbaren Druckleiste 13. Der Winkel β beträgt vorzugsweise 90o, kann jedoch zwischen 45o und 95o liegen. Die Sekante 45 verläuft im oberen Drittel i der Gesamttiefe des Zylinderkanals 2; 3. Die Druckplatte 36 wird gespannt. Beim Spannen der Druckplatte 36 erfolgt nicht nur eine radiale Bewegung der Druckleiste 13, sondern eine ausgleichende axiale Bewegung in Richtung K, solange, bis die voreingestellte Stromaufnahme des Motors 28 erreicht ist, und der Motor 28 abschaltet. Die maximal zurückzulegenden Wege h; i der Keilflächen 17; 18 und 29 der Druckleiste 13 können gleich sein. Die Kraft wird ohne Biegemoment als Druckkraft direkt auf die Spannschiene 33 übertragen. Die Krafteinleitung erfolgt unweit von der Druckplatte 36, nahezu an der oberen Kanalseitenwand 14. Als Motor 28 kann auch ein Pneumatikmotor verwendet werden.1 and 4 operates as follows. A pressure plate 36 is held in a clamping device, not shown in FIG. 4, but arranged in mirror image fashion beyond the center line 37, applied to the outer surface of the plate cylinder 1 and between the tensioning rail 33 and the clamping rail 34 by a not described, but z. B. according to DE 36 04 071 C2 known mechanism. The motor 28, which is designed as a DC motor with torque limitation and positioning device, drives via the transmission 27; 26; 24; 22; 23; 6 on the internally threaded wedge 19 which, depending on the direction of rotation of the motor 28, can be moved in the axis-parallel direction E. As a result of the operative connection, which results from the wedge 19 and the wedge-shaped shoulder 18 located on the pressure bar 13 and the operative connection, which results from the bevel 11 of the base 7 and the wedge-shaped paragraph 17, the pressure bar 13 experiences an up and down movement in radial or approximately radial direction F, at most by a distance h. The pressure bar 13 is against its bevel 29 against the dome-shaped end 31 of the set screw 32 is pressed. This results in a movement of the tensioning rail 33 in the direction of a secant 45 to the plate cylinder 1, which the cylinder channel 2; 3 cuts. The secant 45 extends at an angle β to the radially movable pressure bar 13. The angle β is preferably 90 ° , but can be between 45 ° and 95 ° . The secant 45 runs in the upper third i of the total depth of the cylinder channel 2; 3. The pressure plate 36 is tensioned. When the pressure plate 36 is tensioned, there is not only a radial movement of the pressure bar 13, but also a compensating axial movement in the direction K until the preset current consumption of the motor 28 is reached and the motor 28 switches off. The maximum distances to be covered h; i of the wedge surfaces 17; 18 and 29 of the pressure bar 13 can be the same. The force is transmitted directly to the tensioning rail 33 as a compressive force without a bending moment. The force is applied not far from the pressure plate 36, almost on the upper channel side wall 14. A pneumatic motor can also be used as the motor 28.

Die Rückstellung wird infolge Drehrichtungsumkehr des Motors 28 vorgenommen und durch die Wirkung der Federn 38 erleichtert. Für die Einrichtung nach Fig. 1 werden geringe Anforderungen an die Fertigungstoleranzen gestellt; es wird ein einfacher Antrieb benötigt. Im Falle der Verwendung eines Elektromotors als Motor 28, werden die Antriebsenergie, Befehle und Impulse berührungslos in den rotierenden Zylinder 1 übertragen.The reset is carried out as a result of the reversal of the direction of rotation of the motor 28 and is facilitated by the action of the springs 38. For the device according to FIG. 1, low demands are placed on the manufacturing tolerances; a simple drive is required. In the case of using an electric motor as the motor 28, the drive energy, commands and pulses are transmitted to the rotating cylinder 1 without contact.

Dies geschieht in der Weise, daß an einer Stirnseite des Plattenzylinders 1 konzentrisch zur Rotationachse 35 eine Sekundärspule sowie eine Sekundärelektronik angeordnet ist, die sowohl mit einer geringfügig beabstandeten und ebenfalls auf einer konzentrisch zur Rotationsachse 35 fest angeordneten Primärspule zusammenwirkt, die wiederum mit einer in einem Abstand angeordneten Primärelektronik in Verbindung steht.This is done in such a way that a secondary coil and secondary electronics are arranged on an end face of the plate cylinder 1 concentrically with the axis of rotation 35, which cooperates both with a slightly spaced primary coil and also with a primary coil fixedly arranged concentrically with the axis of rotation 35, which in turn cooperates with one in one Distance primary electronics is connected.

Durch diese Anordnung lassen sich sowohl elektrische Motoren von jeweils 40 W mit Strom versorgen. Zusätzlich wird ein Datenstrom übertragen zur Abfrage von Sensoren bzw. zur Ansteuerung von Motoren. Demzufolge steht eine stabile Gleichstromversorgung für die im Zylinder 1 angeordneten Motoren zur Verfügung, unabhängig vom augenblicklichen Drehwinkel. Ein solches berührungsloses Leistungsübertragungssystem wird z. B. von der Fa. Mesa Systemtechnik GmbH in Konstanz angeboten.With this arrangement, both electric motors of 40 W each can be supplied with power. In addition, a data stream is transmitted to query sensors or to control motors. As a result, a stable DC power supply is available for the motors arranged in cylinder 1, regardless of the instantaneous angle of rotation. Such a non-contact power transmission system is e.g. B. offered by Mesa Systemtechnik GmbH in Constance.
