Description

Beschreibung description
Einrichtung zum Spannen und Justieren von biegsamen Druckplatten auf Platt enzyl indem von RotationsdruckmaschinenDevice for clamping and adjusting flexible printing plates on plate enzyl by rotary printing machines
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 threads 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 αie 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 remote-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 αen 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.

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 can be moved in the axis parallel direction E depending on the direction of rotation of the motor 28. As a result of the operative connection, which results from the wedge 19 and the wedge-shaped heel 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 undergoes an up and down movement in the radial or approximately radial direction F, by a maximum of one path 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 A 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, not only does a radial movement of the pressure bar 13 take place, but 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. 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.The reset is carried out as a result of the reversal of the direction of rotation of the motor 28 and 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. 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 to the axis of rotation 35, which cooperates with a slightly spaced primary coil and also on a fixedly arranged concentric to 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 Gleichstromverso gung für die im Zylinder 1 angeordneten Motoren zur Verfügung, unabhängig vom augenblicklichen Dreh inkel . 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. Accordingly, a stable DC power supply is available for the motors arranged in cylinder 1, regardless of the instantaneous rotation angle. Such a non-contact power transmission system is e.g. B. offered by Mesa Systemtechnik GmbH in Constance.
