Definitions
- the invention relates to a device for fastening a flexible pressure plate according to the preamble of patent claim 1.
- DE 31 16 506 C2 shows a device for fastening a flexible pressure plate, which contains a clamping pit with two pit walls running at an acute angle to the cylinder surface.
- Two clamping bodies which are divided in the longitudinal direction of the pit and which clamp the plate legs between themselves and a pit wall, are used for tensioning.
- the plate tension enables an automatic plate change, it requires a wide clamping channel due to the space required for the clamping bodies, which is equivalent to a loss of printing area.
- this object is achieved in a generic device by using the features of the characterizing part of claim 1. Because the device has only one clamping body, the clamping channel can be kept narrow.
- the forme cylinder 1 shown in detail in FIG. 1 has a cylinder pit 2 running in the axial direction. This contains a pit wall 3, 4 running at an acute angle and approximately perpendicular to the cylinder jacket.
- a clamp body 5 cooperates with the pit walls 3, 4 and has clamping surfaces 6, 7 which are parallel to them.
- the clamping body 5 is fixedly arranged on a clamping beam 8, which is supported by means of compression springs 9 in the base of the cylinder pit 2.
- the clamping body 5 can for example be screwed to the clamping beam 8 or pressed into a groove.
- the clamping beam 8 together with the clamping body 5 extends at least over the width of the pressure plate 11.
- the pressure plate 11 is suspended with its leading plate leg 12 on the channel edge formed by the cylinder surface and the pit wall 3. It is clamped between the pit wall 3 and the clamping surface 6. During a subsequent rotation of the forme cylinder 1, the pressure plate is rolled up on it, advantageously using a pressure roller or the employed rubber cylinder. Finally, the trailing plate leg 13 between the pit wall 4 and the clamping body 5th indented. The insertion of the plate legs 12, 13 is facilitated by chamfers on the clamping body 5. To remove the pressure plate 11, the clamping body 5 together with the clamping beam 8 is pressed deeper into the cylinder pit 2 by means of the plate release device 14 against the force of the springs 9.
- the trailing plate leg 13 jumps out of the clamping pit while canceling the wedge effect of the clamping body 5.
- the leading plate leg 12 can also be removed from the plate clamping device after pressing the clamping body 5 again.
- Fig. 2 shows a forme cylinder 16, in which a clamping beam 17 in the cylinder pit 18 extends to the ends of the cylinder jacket, up to the bearer rings 19, 20.
- the clamping body is composed of lined-up clamping pieces 21 which are resiliently received in the clamping beam 17.
- the division into clamping pieces brings manufacturing advantages.
- good clamping of the pressure plate 22 on the pit walls is achieved.
- the cylinder pit 18 corresponds to the geometry of the cylinder pit according to FIG. 1. Only the channel width can be kept narrower in the clamping pit 18 under certain circumstances, since the plate release 14 required in FIG. 1 can be omitted from explanations given below.
- the tensioning beam 17 is supported by means of compression springs 23 in the base of the cylinder pit 18 (FIG.
- Each clamping piece 21 is received in a groove 24 of the clamping beam 17 (Fig. 4). It is supported with springs 25 in the groove base.
- Each clamping piece has unspecified clamping surfaces analogous to those of the clamping body from FIG. 1.
- two sleeves 27 are screwed by means of screws 26 (FIG. 5) with which the clamping pieces 21 can be pushed in bores 28 of the clamping beam 17 in the clamping direction be performed.
- a stop disc 29 is interposed, which covers the bore 28.
- the clamping pieces 21 could also be guided in some other way, for example by means of pins or the side walls of the groove 24.
- a plunger 32, 33 is arranged on each machine side wall 30, 31 and can be moved in the radial direction through a bore 34, 35 of the cylinder jacket of the forme cylinder 16 onto the clamping beam 17.
- the pressure plate 22 is tensioned in the same way as in the previous exemplary embodiment according to FIG. 1.
- the plate legs are tensioned by the clamping pieces 21, which are pressed into the wedge formed by the pit walls by the spring-loaded tensioning beam.
- these spring somewhat into the clamping beam 17, a gap being formed between the stop disk 29 and the bore 28.
- the forme cylinder 16 is positioned so that the bores 34, 35 of the cylinder jacket come to rest under the plungers 32, 33.
- the plungers 32, 33 are extended, the clamping bar 17 is pressed against the force of the compression springs 23 in the direction of the bottom of the clamping pit 18. After the gap between the stop disk 29 and the bore 28 (FIG.
- the clamping pieces 21 are also taken along, i.e. pulled from the wedge formed by the pit walls, and release the plate legs. Because there is no need for plate solvents to be introduced into the clamping channel, the clamping channel can be kept very narrow, for example 2 mm or smaller. Limits for its minimization are practically only set by the printing plate thickness and manufacturing requirements.
- FIG. 6 and 10 show alternative variants for the actuation of clamping beams to FIG. 2. Only the actuating device at the left end of the forme cylinder jacket is shown. A similar device is located at the right end of the jacket. 6, the clamping beam 37 extends into the bearer ring 38 and ends in the region of a pressure chamber 39. The latter has a membrane 40 which can be deflected radially towards the clamping beam 37 and is connected to the connecting bore 41 through the cylinder jacket Outdoor atmosphere in connection.
- the connecting shoe 43 of a compressed air source can be placed on the latter by means of a lifting device 42.
- the connecting shoe 43 has the curvature of the cylinder jacket (FIG. 7), and its connecting opening 44 advantageously has the shape of an elongated hole (FIG. 8). Thanks to this elongated hole shape, the connection bore 41 does not need to be positioned exactly under the connection shoe 43 in order to release the pressure plate.
- connection bore 45 of a pressure chamber leads out of the forme cylinder 46 at the end.
- a connection opening 47 of the connection shoe 48 is designed in the form of a circular segment, and the latter is surrounded by a flat sealing surface.
- the forme cylinder 36 In order to release the pressure plate, the forme cylinder 36 is positioned with its connection bore 41 under the connection shoe 43. After the connection shoe 43 has been lowered onto the lateral surface of the forme cylinder 36, the pressure chamber 39 is filled with compressed air, whereupon the membrane 40 presses the clamping bar 37 inwards. Similar to the previous example, the plate legs are released.
- the clamping beam 49 of the forme cylinder 50 has an inclined plane 51.
- a plunger 53 attached to the machine side wall 52 also carries an inclined plane 54.
- the inclined planes 51 and 54 slide against one another and move the clamping beam 49 radially inward, the plate legs being released. The further loosening and also the tensioning of the printing plates takes place as indicated in the first embodiment.
- the forme cylinder has only one cylinder pit for tensioning a printing plate. Also belonging to the scope of protection of the patent, several pits can be arranged on the circumference of the forme cylinder to evenly distribute a corresponding number of pressure plates.

Description
Die Erfindung betrifft eine Vorrichtung zum Befestigen einer biegsamen Druckplatte nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for fastening a flexible pressure plate according to the preamble of
Die DE 31 16 506 C2 zeigt eine Vorrichtung zum Befestigen einer biegsamen Druckplatte, die eine Spanngrube mit zwei spitzwinklig zur Zylindermantelfläche verlaufende Grubenwände enthält. Zur Spannung dienen zwei in Grubenlängsrichtung geteilte Klemmkörper, die zwischen sich und einer Grubenwand die Plattenschenkel klemmen. Zwar ermöglicht die Plattenspannung einen automatischen Plattenwechsel, sie bedingt jedoch wegen des Platzbedarfes für die Klemmkörper einen breiten Spannkanal, was einem Verlust an Druckfläche gleichkommt.DE 31 16 506 C2 shows a device for fastening a flexible pressure plate, which contains a clamping pit with two pit walls running at an acute angle to the cylinder surface. Two clamping bodies, which are divided in the longitudinal direction of the pit and which clamp the plate legs between themselves and a pit wall, are used for tensioning. Although the plate tension enables an automatic plate change, it requires a wide clamping channel due to the space required for the clamping bodies, which is equivalent to a loss of printing area.
Es ist Aufgabe der Erfindung, eine für einen automatischen Plattenwechsel geeignete Plattenspannung zu schaffen, die nur einen engen Spannkanal aufweist.It is an object of the invention to provide a plate tension which is suitable for an automatic plate change and which has only a narrow clamping channel.
Erfindungsgemäß wird diese Aufgabe bei einer gattungsgemäßen Vorrichtung durch die Anwendung der Merkmale des Kennzeichens des Anspruchs 1 gelöst. Dadurch, daß die Vorrichtung nur einen Klemmkörper aufweist, kann der Spannkanal schmal gehalten werden.According to the invention, this object is achieved in a generic device by using the features of the characterizing part of

Der in Fig. 1 ausschnittweise dargestellte Formzylinder 1 weist eine in Achsrichtung verlaufende Zylindergrube 2 auf. Diese enthält eine spitzwinklig und eine etwa senkrecht zum Zylindermantel verlaufende Grubenwand 3, 4. Mit den Grubenwänden 3, 4 arbeitet ein Klemmkörper 5 zusammen, der voteilhaft zu ihnen parallele Klemmflächen 6, 7 besitzt. Der Klemmkörper 5 ist fest an einem Spannbalken 8 angeordnet, der sich mittels Druckfedern 9 im Grund der Zylindergrube 2 abstützt. Der Klemmkörper 5 kann beispielsweise an den Spannbalken 8 angeschraubt oder in eine Nut eingepreßt sein. Der Spannbalken 8 mitsamt dem Klemmkörper 5 erstreckt sich zumindest über die Breite der Druckplatte 11.The
Die Druckplatte 11 wird mit ihrem vorlaufenden Plattenschenkel 12 an der von der Zylindermantelfläche und der Grubenwand 3 gebildeten Kanalkante eingehängt. Sie wird dabei zwischen der Grubenwand 3 und der Klemmfläche 6 geklemmt. Bei einer nachfolgend stattfindenden Umdrehung des Formzylinders 1 wird die Druckplatte auf diesen aufgerollt, vorteilhaft unter Benutzung einer Andrückrolle oder des angestellten Gummizylinders. Abschließend wird der nachlaufende Plattenschenkel 13 zwischen die Grubenwand 4 und den Klemmkörper 5 eingedrückt. Das Einschieben der Plattenschenkel 12, 13 wird durch Einführschrägen am Klemmkörper 5 erleichtert. Zur Entnahme der Druckplatte 11 wird der Klemmkörper 5 mitsamt dem Spannbalken 8 mittels des Plattenlösers 14 entgegen der Kraft der Federn 9 tiefer in die Zylindergrube 2 gedrückt. Dabei springt unter Aufhebung der Keilwirkung des Klemmkörpers 5 zunächst der nachlaufende Plattenschenkel 13 aus der Spanngrube. Nach dem Abwickeln der Druckplatte 11 vom Zylindermantel kann nach nochmaligem Drücken auf den Klemmkörper 5 auch der vorlaufende Plattenschenkel 12 aus der Plattenspannvorrichtung entnommen werden.The
Fig. 2 zeigt einen Formzylinder 16, bei dem ein Spannbalken 17 in der Zylindergrube 18 bis an die Enden des Zylindermantels, bis an die Schmitzringe 19, 20, reicht. Außerdem ist der Klemmkörper aus aneinandergereihten Klemmstücken 21 zusammengesetzt, die federnd im Spannbalken 17 aufgenommen sind. Die Aufteilung in Klemmstücke bringt Fertigungsvorteile. Außerdem wird eine gute Klemmung der Druckplatte 22 an den Grubenwänden erzielt. Die Zylindergrube 18 stimmt übrigens mit der Geometrie der Zylindergrube gemäß Fig. 1 überein. Lediglich die Kanal breite kann bei der Spanngrube 18 unter Umständen schmaler gehalten werden, da aus weiter unten gemachten Erklärungen der in Fig. 1 erforderliche Plattenlöser 14 entfallen kann. Der Spannbalken 17 stützt sich mittels Druckfedern 23 im Grund der Zylindergrube 18 ab (Fig. 3). Jedes Klemmstück 21 wird in einer Nut 24 des Spannbalkens 17 aufgenommen (Fig. 4). Es stützt sich mit Federn 25 im Nutgrund ab. Jedes Klemmstück besitzt nicht näher bezeichnete Klemmflächen analog denen des Klemmkörpers aus Fig. 1. An der Unterseite jedes Klemmstückes 21 sind mittels Schrauben 26 zwei Hülsen 27 angeschraubt (Fig. 5), mit denen die Klemmstücke 21 in Bohrungen 28 des Spannbalkens 17 in Spannrichtung schiebbar geführt werden. Zwischen der Hülse 27 und dem Kopf der Schraube 26 ist eine Anschlagscheibe 29 zwischengelegt, die die Bohrung 28 überdeckt. Die Führung der Klemmstücke 21 könnte auch anderweitig, beispielsweise mittels Stiften oder der Seitenwände der Nut 24 erfolgen. An jeder Maschinenseitenwand 30, 31 ist ein Stößel 32, 33 angeordnet, der durch eine Bohrung 34, 35 des Zylindermantels des Formzylinders 16 in radialer Richtung auf den Spannbalken 17 fahrbar ist.Fig. 2 shows a
Das Spannen der Druckplatte 22 erfolgt auf gleiche Weise, wie beim vorherigen Ausführungsbeispiel gemäß Fig. 1. Die Plattenschenkel werden von den Klemmstücken 21, die vom federbelasteten Spannbalken in den von den Grubenwänden gebildeten Keil gedrückt werden, gespannt. Zur gesicherten Anlage der Klemmstücke 21 federn diese etwas in den Spannbalken 17 ein, wobei sich dabei zwischen der Anschlagscheibe 29 und der Bohrung 28 ein Spalt bildet. Zwecks Lösen der Druckplatte 22 wird der Formzylinder 16 so positioniert, daß die Bohrungen 34, 35 des Zylindermantels unter den Stößeln 32, 33 zu liegen kommen. Beim Ausfahren der Stößel 32, 33 wird der Spannbalken 17 entgegen der Kraft der Druckfedern 23 in Richtung des Grundes der Spanngrube 18 gedrückt. Nach Überwindung des Spaltes zwischen der Anschlagscheibe 29 und der Bohrung 28 (Fig. 5) werden dabei auch die Klemmstücke 21 mitgenommen, d.h. aus dem von den Grubenwänden gebildeten Keil gezogen, und geben die Plattenschenkel frei. Durch das Nichterfordernis von in den Spannkanal einzuführenden Plattenlösemitteln kann der Spannkanal sehr schmal gehalten werden, beispielsweise 2 mm oder kleiner. Grenzen für seine Minimierung werden praktisch nur noch durch die Druckplattendicke und Belange der Fertigung gesetzt.The
Die Fig. 6 und 10 zeigen zur Fig. 2 alternative Varianten zur Betätigung von Spannbalken. Gezeigt wird jeweils nur die Betätigungseinrichtung am linken Ende des Formzylindermantels. Eine gleichartige Einrichtung befindet sich am rechten Ende des Mantels. Bei dem Formzylinder gemäß Fig. 6 reicht der Spannbalken 37 bis in den Schmitzring 38 hinein und endet im Bereich einer Druckkammer 39. Letztere weist eine radial auf den Spannbalken 37 hin auslenkbare Membran 40 auf und steht über eine durch den Zylindermantel führende Anschlußbohrung 41 mit der Außenatmosphäre in Verbindung. Auf letztere ist mittels einer Hubvorrichtung 42 der Anschlußschuh 43 einer Druckluftquelle aufsetzbar. Der Anschlußschuh 43 weist die Krümmung des Zylindermantels auf (Fig. 7), und seine Anschlußöffnung 44 hat vorteilhaft die Form eines Langloches (Fig. 8). Dank dieser Langlochform braucht für ein Lösen der Druckplatte die Anschlußbohrung 41 nicht exakt unter dem Anschlußschuh 43 positioniert zu werden.6 and 10 show alternative variants for the actuation of clamping beams to FIG. 2. Only the actuating device at the left end of the forme cylinder jacket is shown. A similar device is located at the right end of the jacket. 6, the
Gemäß Fig. 9 führt die Anschlußbohrung 45 einer Druckkammer stirnseitig aus dem Formzylinder 46 heraus. Hier ist eine Anschlußöffnung 47 des Anschlußschuhs 48 in Form eines Kreissegmentes ausgeführt, und letzteres ist von einer ebenen Dichtfläche umgeben.According to FIG. 9, the connection bore 45 of a pressure chamber leads out of the
Zwecks Lösen der Druckplatte wird der Formzylinder 36 mit seiner Anschlußbohrung 41 unter dem Anschlußschuh 43 positioniert. Nach Absenken des Anschlußschuhs 43 auf die Mantelfläche des Formzylinders 36 wird die Druckkammer 39 mit Druckluft gefüllt, worauf die Membran 40 den Spannbalken 37 nach innen drückt. Analog zum vorherigen Beispiel werden dabei die Plattenschenkel freigegeben.In order to release the pressure plate, the
Gemäß Fig. 10 weist der Spannbalken 49 des Formzylinders 50 eine schiefe Ebene 51 auf. Ein an der Maschinenseitenwand 52 befestigter Stößel 53 trägt ebenfalls eine schiefe Ebene 54. Beim Ausfahren des Stößels 53 gleiten die schiefen Ebenen 51 und 54 aufeinander ab und bewegen den Spannbalken 49 radial nach innen, wobei die Plattenschenkel freigegeben werden. Das weitere Lösen und auch das Spannen der Druckplatten erfolgt, wie beim ersten Ausführungsbeispiel angegeben.10, the
In den Ausführungsbeispielen weist der Formzylinder nur eine Zylindergrube zur Spannung einer Druckplatte auf. Ebenfalls zum Schutzumfang des Patentes gehörig können am Umfang des Formzylinders gleichmäßig verteilt mehrere Gruben zur Spannung einer entsprechenden Anzahl Druckplatten angeordnet sein.In the exemplary embodiments, the forme cylinder has only one cylinder pit for tensioning a printing plate. Also belonging to the scope of protection of the patent, several pits can be arranged on the circumference of the forme cylinder to evenly distribute a corresponding number of pressure plates.
