Description

Die Erfindung betrifft eine Vorrichtung zum Halten des unteren Aufzuges eines zweilagigen Aufzuges auf der Mantelfläche eines Gummizylinders in Druckmaschinen, wobei der obere Aufzug die Vorrichtung für den unteren Aufzug im wesentlichen überdeckt und sich über die Länge des Gummizylinders erstreckt, insbesondere bei Bogendruckmaschinen.The invention relates to a device for holding the lower elevator of a two-layer elevator on the outer surface of a blanket cylinder in printing presses, the upper lift essentially covering the device for the lower lift and extending over the length of the blanket cylinder, in particular in sheet-fed printing machines.

In der EP-Anmeldung 0 070 378 ist eine Vorrichtung bekannt geworden, bei der die Haltevorrichtung für den unteren Aufzug als eine sich über die Länge des Gummizylinders erstreckende Halteschiene,die im wesentlichen mit einem kreisförmigen Querschnitt gebildet ist, wobei diese sich über eine stirnseitige sowie zwei achsparallele Anlagestellen am Gummizylinder abstützt. Es sind registerhaltige Haltebolzen verteilt angeordnet, die Stanzlöcher des unteren Aufzuges aufnehmen können. Aufgabe dieser Vorrichtung soll es sein, daß sie raumsparend aufgebaut ist und der untere Aufzug rasch auf der Haltevorrichtung befestigt werden kann, wobei dieser stets achsparallel mit einem vorgegebenen Abstand zur Gummizylinderaußenkante positioniert ist.In EP application 0 070 378 a device has become known in which the holding device for the lower elevator as a holding rail extending over the length of the rubber cylinder, which is essentially formed with a circular cross-section, which extends over a front and supports two axially parallel contact points on the rubber cylinder. There are register-holding bolts distributed, which can accommodate punch holes in the lower elevator. The object of this device should be that it be constructed in a space-saving manner and that the lower elevator can be quickly attached to the holding device, said elevator always being positioned axially parallel with a predetermined distance from the outer edge of the rubber cylinder.

Für den Drucker besteht das Problem die Stanzlöcher für jeden einzelnen unteren Aufzug erst einmal so zu positionieren, daß die Stanzlöcher beim Einlegen des unteren Aufzuges in die registerhaltigen Haltebolzen der Haltevorrichtung passen und dann den schwierigen Lochungsvorgang durchzuführen. Die weitere Schwierigkeit besteht beim Einlegen des unteren Aufzuges in die Druckmaschine selbst. Es hat sich gezeigt, daß die Drucker oftschwierigkeiten haben, die Haltevorrichtung für den unteren Aufzug montieren bzw. demontieren zu können. Weitere Schwierigkeiten ergeben sich, wenn die unteren Aufzüge mehrmals verwendet werden und die Stanzlöcher sich während des ersten oder zweiten Druckauftrags an den registerhaltigen Haltebolzen der Haltevorrichtung aufgeweitet haben.The problem for the printer is to position the punch holes for each individual lower elevator so that the punch holes fit into the register-holding bolts of the holding device when the lower elevator is inserted and then to carry out the difficult perforation process. The further difficulty lies in inserting the lower elevator into the printing machine itself. It has been shown that the printer is often difficult have the ability to assemble or disassemble the holding device for the lower elevator. Further difficulties arise if the lower lifts are used several times and the punch holes have widened during the first or second print job on the register-holding pins of the holding device.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die die genannten Nachteile vermeidet und dabei eine kostengünstige sowie sicher im Zylinder befestigbare Papierspannschiene ist.Based on this prior art, the invention has for its object to provide a device of the type mentioned, which avoids the disadvantages mentioned and is an inexpensive and securely fastened in the cylinder paper tensioning rail.

Erfindungsgemäß wird die Vorrichtung der eingangs genannten Art durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 erreicht.According to the invention, the device of the type mentioned is achieved by the features of the characterizing part of claim 1.

Die Vorrichtung ist aus zwei über Scharniere drehbar miteinander verbundenen Papierspannschienen gebildet. Der Drucker hat damit lediglich beim Montieren nur ein Teil und die Bögen des Aufzuges in den Händen. Bei einer Papierspannschiene die aus mehreren Teilen zusammengesetzt ist, wobei diese lose sind, können während der Arbeiten Teile verlegt werden, was die Montagezeit erhöhen kann.The device is formed from two paper tensioning rails which are rotatably connected to one another via hinges. The printer only has a part of the assembly and the arches of the elevator in his hands. In the case of a paper tensioning rail which is composed of several parts, these being loose, parts can be laid during the work, which can increase the assembly time.

Besonders einfach ist das Einlegen der einzelnen Bögen des Aufzuges in die geöffnete Papierspannschiene. In der normalen Ausführung z.B. für große Formate sind 4 Scharniere über die ganze Länge der Papierspannschiene vorgesehen. Die Scharniere haben einen ungefähren Abstand von 250 - 280 mm zueinander und sind in Paaren jeweils im äußeren Drittel an der Papierspannschiene angeordnet. Aus der Seitenansicht gesehen, befindet sich der Drehpunkt der Scharniere in der Mitte der beiden Auflageflächen der Papierspannschienen. Das bedeutet, je mehr Papierbögen in die Papierspannschiene eingelegt werden, desto größer wird die Haltekraft der Scharniere bei geschlossener Papierspannschiene, da diese um das Dickenmaß der Papierbögen auseinander gespannt werden.It is particularly easy to insert the individual sheets of the elevator into the open paper tensioning rail. In the normal version, for example for large formats, 4 hinges are provided over the entire length of the paper tensioning rail. The hinges are approximately 250 - 280 mm apart and are arranged in pairs in the outer third on the paper tensioning rail. Seen from the side view, the pivot point of the hinges is in the middle of the two contact surfaces of the paper tensioning rails. This means that the more sheets of paper are inserted into the paper tensioning rail, the greater the holding force of the hinges when the paper tensioning rail is closed, since these are stretched apart by the thickness of the paper sheets.

Die Papierspannschienen sind mittels mindestens zwei an einer Papierspannschiene drehbar befestigten Klemmfedern zusammenpreßbar. Zum öffnen der Papierspannschiene werden die Klemmfedern durch eine einfache Drehbewegung in eine rechtwinkelige Stellung zur Papierspannschiene verdreht. Danach lassen sich die beiden Papierspannschienen um den Drehpunkt der Scharniere gut auseinanderklappen und die Papierbogen des unteren Aufzuges herausnehmen oder wieder einlegen.The paper tensioning rails can be pressed together by means of at least two clamping springs which are rotatably attached to a paper tensioning rail. To open the paper tensioning rail, the clamping springs are turned into a right-angled position relative to the paper tensioning rail by a simple rotary movement. Then the two paper tensioning rails can be folded out well around the pivot point of the hinges and the paper sheets of the lower elevator can be removed or reinserted.

Die Verteilung der Klemmfedern in Längsrichtung der Papierspannschiene gesehen ist so gewählt, daß ca. drei Klemmfedern um die beiden Scharniere herum ange-ordnet sind, d.h. alternierend eine Klemmfeder,ein Scharnier usw.. Sind die Papierbögen des unteren Aufzuges zwischen die Papierspannschienen eingelegt und die Klemmfedern geschlossen, dann ist der untere Aufzug rutschfest in der Papierspannschiene gehaltert.Seen the distribution of the clamping springs in the longitudinal direction of the paper clamping rail is selected so that approximately three clamping springs are arranged e-about the two hinges around to g, ie alternately etc a clamping spring, a hinge .. If the paper sheets of the lower elevator between the paper clamping bars inserted and the clamping springs are closed, then the lower elevator is held non-slip in the paper tensioning rail.

Die Papierspannschienen sind mittels mindestens zwei selbstsichernden Lagerböcken, die am Gummizylinder befestigt sind, leicht lösbar gehaltert. Die Lagerböcke arretieren die Papierspannschiene nach dem Einlegen durch den Drucker in der optimalen Position am Gummizylinder. Dabei ist die Position so gewählt, daß der Aufzug weit über rechtwinkelig zur Papierspannschiene in Richtung der Mantelfläche des Gummizylinders abgewinkelt wird. D.h. die Klemmfläche der Papierspannschiene wird nicht auf Zug beansprucht, sondern der mögliche Zug wird durch die Abwinkelung des unteren Aufzugs in ein Kippmoment an der Papierspannschiene, das durch den Lagerbock aufgenommen wird, umgewandelt.The paper tensioning rails are easily detachably supported by means of at least two self-locking pedestals, which are attached to the rubber cylinder. The bearing blocks lock the paper tensioning rail in the optimal position on the rubber cylinder after insertion by the printer. The position is chosen so that the elevator is angled far beyond perpendicular to the paper tensioning rail in the direction of the outer surface of the blanket cylinder. This means that the clamping surface of the paper tensioning rail is not subjected to tension, but the possible tension is converted by the bending of the lower elevator into a tilting moment on the paper tensioning rail, which is taken up by the bearing block.

Die Lagerböcke verriegeln sich zusätzlich durch diesen Kippmoment. Durch ein leichtes Öffnen der Lagerböcke kann der Drucker die Papierspannschiene schnell und einfach aus der Halterung wieder entfernen.The bearing blocks also lock due to this tilting moment. The printer can quickly and easily remove the paper clamping rail from the holder by simply opening the pedestals.

In einer besonders vorteilhaften Ausgestaltung weisen die Papierspannschienen über ihre gesamte Länge und Breite an ihrer innenliegenden Seite eine profilierte Klemmfläche auf. Der untere Aufzug braucht nicht mehr gelocht zu werden und kann immer in die gleiche Position durch Anlage an die Drehpunkte der Scharniere angelegt werden und mit der Klemmfläche optimal fixiert werden.In a particularly advantageous embodiment, the paper tensioning rails have a profiled clamping surface over their entire length and width on their inner side. The lower elevator no longer needs to be punched and can always be placed in the same position by resting on the pivot points of the hinges and optimally fixed with the clamping surface.

Die Scharniere sind mit einem definierten Abstand zu den Klemmfedern an der Papierspannschiene befestigt. Der Abstand beträgt ca. 10 cm.The hinges are attached to the paper tensioning rail at a defined distance from the clamping springs. The distance is about 10 cm.

Durch diesen Abstand vom Scharnier zur Klemmfeder entsteht eine Hebelwirkung zwischen diesen, die eine zusätzliche Haltekraft über die Papierspannschiene auf dem unteren Aufzug erzeugt. Die Hebelwirkung entsteht aus der geometrischen Anordnung auch in Längsrichtung der Papierspannschiene gesehen zwischen den Scharnieren und der Klemmt feder, da der Drehpunkt der Scharniere außerhalb der Papierspannschiene angeordnet ist und der Druckpunkt der Klemmfeder in geschlossenem Zustand ca. im letzten Drittel der Breite der Papierspannschiene vorgesehen ist. Die Entfernung zwischen Druckpunkt und Drehpunkt entspricht einem Hebelarm.This distance from the hinge to the clamping spring creates a leverage effect between them, which creates an additional holding force via the paper tensioning rail on the lower elevator. The leverage arises from the geometric arrangement also seen in the longitudinal direction of the paper tensioning rail between the hinges and the clamping spring, since the pivot point of the hinges is arranged outside the paper tensioning rail and the pressure point of the clamping spring in the closed state approximately in the last third of the Width of the paper tensioning rail is provided. The distance between the pressure point and the fulcrum corresponds to a lever arm.

Die Klemmfedern sind an der Papierspannschiene beweglich vernietet und weisen an ihrem einen Ende Verstärkungsösen auf. Die Klemmfedern sind damit ein besonders billig aus Blech herzustellendes Massenfertigungsprodukt. Die Verstärkungsösen erhöhen den Federdruck und die Stabilität der Klemmfedern.The clamping springs are movably riveted to the paper tensioning rail and have reinforcement eyelets at one end. The clamping springs are therefore a particularly cheap mass-produced product from sheet metal. The reinforcement eyelets increase the spring pressure and the stability of the clamping springs.

Die Lagerböcke weisen eine Klinke auf und der Drehpunkt der Verriegelung ist so gewählt, daß bei einem Druck der Papierspannschiene auf die Klinke diese automatisch verriegelt ist.The pedestals have a pawl and the pivot point of the lock is selected so that when the paper tensioning rail is pressed onto the pawl, it is automatically locked.

Durch einen Druck mit dem Daumen kann die Klinke leicht nach hinten gekippt werden, so daß der Drucker die Papierspannschiene leicht herausnehmen kann ohne ein Werkzug dabei zu benutzen.By pressing the thumb, the latch can be tilted backwards slightly so that the printer can easily remove the paper tensioning rail without using a tool.

Die Lagerböcke sind besonders einfach mit einer Schraube am Gummizylinder verschraubt, so daß die Montage sehr kostengünstig ist. Die Klinke ist mittels einer Druckfeder in ihre Verschlußstellung bringbar, wobei auch unterschiedlich starke Aufzüge verwendbar sind. Für den Drucker ist das selbsttätige Verriegeln bei der Montage der Papierspannschiene sehr hilfreich und zeitverkürzend.The bearing blocks are screwed to the rubber cylinder with a screw in a particularly simple manner, so that assembly is very cost-effective. The pawl can be brought into its closed position by means of a compression spring, lifts of different strengths being usable. For the printer, automatic locking when mounting the paper tensioning rail is very helpful and time-saving.

Die Klemmfedern sind gehärtet und angelassen und weisen Verstärkungsösen auf, die in Spannschienenrichtung einen Radius von ca. 50 mm besitzen. Die Verstärkungsösen sind damit so gebogen, daß die Klemmfedern nur mit einem Druckpunkt die Papierspannschienen zusammendrücken. Die gebogenen Verstärkungsösen haben noch den Vorteil, daß die Klemmfedern während der Druckbewegung, d.h. wenn die Papierspannschiene geschlossen werden soll, durch die Anschrägung ohne größeren Widerstand auf die Papierspannschiene aufgeschoben werden kann. Die Papierspannschiene ist zusätzlich auf der Seite, auf der die Klemmfedern aufgeschoben werden, ausgeschrägt.The clamping springs are hardened and tempered and have reinforcement eyelets that have a radius of approx. 50 mm in the direction of the tensioning rail. The reinforcement eyelets are thus bent so that the clamping springs only press the paper tensioning rails together with one pressure point. The curved Reinforcement eyelets also have the advantage that the clamping springs can be pushed onto the paper tensioning rail without greater resistance due to the bevel during the printing movement, ie when the paper tensioning rail is to be closed. The paper tensioning rail is also beveled on the side on which the clamping springs are slid on.

Die Klemmfedern sind an einer Seite der Papierspannschiene mit einem Niet befestigt, um den die Klemmfedern drehbar sind.The clamping springs are attached to one side of the paper tensioning rail with a rivet, around which the clamping springs can be rotated.

In geschlossenem Zustand der Papierspannschiene sind die punktgeschweißten Scharniere vorgespannt.The spot welded hinges are pretensioned when the paper tensioning rail is closed.

Weitere Vorteile und wesentliche Merkmale gehen aus der Figurenbeschreibung hervor.Further advantages and essential features emerge from the description of the figures.

In der Figur 1 ist ein Teilausschnitt eines unteren Aufzuges 1 gezeigt, der auf der Mantelfläche eines .zylinders 3 einer nicht näher gezeigten Druckmaschine aufliegt. Insgesamt ist auf dem Gummizylinder 3 ein zweilagiger Aufzug 2 angeordnet. Der obere Aufzug des zweilagigen Aufzugs 2 überdeckt den Halterungsbereich des unteren Aufzuges 1. Der untere Aufzug 1 ist an seinem Ende zwischen einer Papierspannschiene 5, 6 mittig gehalten. Die Papierspannschiene 5, 6 ist in einem Lagerbock 8 so fixiert, daß der untere Aufzug 1 nahezu rechtwinklig zur mittigen Einspannung in der Papierspannschiene 5, 6 angeordnet ist. An dem Lagerbock 8 ist eine Klinke 11 beweglich befestigt, welche die Papierspannschiene 5, 6 in dieser Position nach dem Einlegen automatisch verriegelt. Hierzu dient eine innerhalb des Lagerbockes 8 angeordnete Druckfeder 12. Die Klinke 11 wird durch die Druckfeder 12 in ihre Verriegelungsposition gedrückt. Der Lagerbock 8 weist in seinem oberen Bereich eine schräg angeordnete Anlagefläche 15 auf, so daß die Papierspannschiene 5, 6 die günstige oben genannte Position im Gummizylinder 3 erhält. Der Lagerbock 8 ist mit einer Schraube 13 am Druckzylinder 3 verschraubt.FIG. 1 shows a partial section of a lower elevator 1, which rests on the outer surface of a cylinder 3 of a printing machine, not shown in any more detail. Overall, a two-layer elevator 2 is arranged on the rubber cylinder 3. The upper elevator of the two-layer elevator 2 covers the mounting area of the lower elevator 1. The lower elevator 1 is held in the middle at its end between a paper tensioning rail 5, 6. The paper tensioning rail 5, 6 is fixed in a bearing block 8 such that the lower elevator 1 is arranged almost at right angles to the central clamping in the paper tensioning rail 5, 6. A pawl 11 is movably attached to the bearing block 8 and automatically locks the paper tensioning rail 5, 6 in this position after insertion. A compression spring 12 arranged inside the bearing block 8 is used for this purpose. The pawl 11 is pressed into its locking position by the compression spring 12. The bearing block 8 has an obliquely arranged contact surface 15 in its upper region, so that the paper tensioning rail 5, 6 receives the favorable position mentioned above in the rubber cylinder 3. The bearing block 8 is screwed to the pressure cylinder 3 with a screw 13.

Von der Mitte der Papierspannschiene 5, 6 aus gesehen im letzten Drittel der Papierspannschiene 5, 6 sind alternierend Klemmfedern 7 und Scharniere 4 angeordnet. Die Scharniere 4 sind um 150° drehbar an einer Papierspannschiene 5 befestigt und können in aufgestecktem Zustand die Papierspannschienen 5, 6 optimal zusammenklemmen. Die Scharniere 4 sind an den Außenseiten der Papierspannschienen 5, 6 angepunktet. Der Drehpunkt der Scharniere 4 befindet sich auf der Seite, nach der sich die Klemmfedern 7 hin öffnen. Die Papierspannschienen 5, 6 können um den Drehpunkt der Scharniere 4 auf- und zugeklappt werden, um die Papierbögen des unteren Aufzuges 1 einzulegen bzw. herauszunehmen. Die Scharniere 4 weisen eine Vorspannung auf, wenn die Papierspannschiene 5, 6 geschlossen ist. Eine zusätzliche Haltekraft entsteht in geschlossenem Zustand durch eine Hebelwirkung innerhalb der Papierspannschiene 5, 6 zwischen dem Druckpunkt der Klemmfedern 7 auf der Papierspannschiene 6 und dem Drehpunkt der Scharniere 4 über deren Vorspannung.In Figure 2, the paper tensioning rail 5, 6 is shown in partial section. Seen from the center of the paper tensioning rail 5, 6 in the last third of the paper tensioning rail 5, 6, clamping springs 7 and hinges 4 are arranged alternately. The hinges 4 are fastened to a paper tensioning rail 5 so that they can be rotated through 150 ° and can optimally clamp the paper tensioning rails 5, 6 in the attached state. The hinges 4 are dotted on the outer sides of the paper tensioning rails 5, 6. The pivot point of the hinges 4 is on the side towards which the clamping springs 7 open. The Paper tensioning rails 5, 6 can be opened and closed about the pivot point of the hinges 4 in order to insert or remove the paper sheets of the lower elevator 1. The hinges 4 are preloaded when the paper tensioning rail 5, 6 is closed. An additional holding force is generated in the closed state by a lever effect within the paper tensioning rail 5, 6 between the pressure point of the clamping springs 7 on the paper tensioning rail 6 and the pivot point of the hinges 4 via their pretension.

In der Figur 3 ist ein Detail der Papierspannschienen 5, 6 im Bereich der Klemmfeder 7 gezeigt. Die Klemmfeder 7 ist mit einem Niet 14 an der Papierspannschiene 5 befestigt. Die Klemmfeder 7 ist um den Niet 14 drehbar und klemmt die Papierspannschienen 5, 6 in geschlossenem Zustand zusammen. Die Innenseiten der Papierspannschienen 5, 6 weisen eine geriffelte Klemmfläche 9 auf. Die Klemmfläche 9 erhöht die Stabilität des unteren Aufzuges 1 in den Papierspannschienen 5, 6.FIG. 3 shows a detail of the paper tensioning rails 5, 6 in the area of the clamping spring 7. The clamping spring 7 is fastened to the paper tensioning rail 5 with a rivet 14. The clamping spring 7 is rotatable about the rivet 14 and clamps the paper tensioning rails 5, 6 together in the closed state. The inside of the paper tensioning rails 5, 6 have a corrugated clamping surface 9. The clamping surface 9 increases the stability of the lower elevator 1 in the paper tensioning rails 5, 6.

Figur 4 zeigt die Papierspannschienen 5, 6 im Schnitt. Die Papierspannschienen 5, 6 liegen parallel zueinander und sind an der Stirnseite, über die die Klemmfeder 7 beim Schließvorgang geschoben wird, angeschrägt. Damit kann eine große Haltekraft zwischen den Papierspannschienen 5, 6 erzeugt werden, da die Vorspannung der Klemmfeder 7 groß gewählt werden kann, ohne daß es passieren kann, daß die Klemmfeder 7 nicht mehr auf die Papierspannschienen 5, 6 geschoben werden kann. Die Klemmfeder 7 weist auf der anderen Seite ihrer Befestigung (Niet 14) die Verstärkungsöse 10 auf, wobei diese zusätzlich in sich gebogen ist. Damit erleichtert sich der Schließvorgang der Klemmfeder 7. Eine weitere Erleichterung für das Schließen sind Anschrägungen an den Stirnseiten der Papierspannschienen 5, 6.Figure 4 shows the paper tensioning rails 5, 6 in section. The paper tensioning rails 5, 6 are parallel to one another and are chamfered on the end face over which the clamping spring 7 is pushed during the closing process. A large holding force can thus be generated between the paper tensioning rails 5, 6, since the pretensioning of the clamping spring 7 can be chosen to be large without it being possible for the clamping spring 7 to no longer be pushed onto the paper tensioning rails 5, 6. The clamping spring 7 has on the other side of its fastening (rivet 14) the reinforcement eyelet 10, which is additionally bent in itself. This simplifies the closing process of the clamping spring 7. A further relief for the closing is bevels on the end faces of the paper tensioning rails 5, 6.
