Description

Die Erfindung betrifft eine Lagerung für Formatzylinder einer Druckmaschine, vorzugsweise einer Flexodruckmaschine, mit austauschbaren hülsenförmigen Formatzylindermänteln nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bearing for format cylinders of a printing press, preferably a flexographic printing press, with exchangeable sleeve-shaped format cylinder jackets according to the preamble of patent claim 1.

Um eine Flexodruckmaschine möglichst schnell auf einen neuen Auftrag umrüsten zu können, ist es bekannt, auf einen Formatzylinderkern, der leicht konisch ausgebildet sein kann, einen aus einer Hülse bestehenden Format- oder Klischeezylindermantel aufzuschieben, der allein bei einem Auftragswechsel gegen einen neuen ausgetauscht wird. Das Austauschen nur des aus einer Hülse bestehenden Formatzylindermantels macht es nun erforderlich, lediglich ein Lager des Formatzylinders auszubauen, so daß der aus einer Hülse bestehende Formatzylindermantel von dem Formatzylinderkern abgezogen und ein neuer Formatzylindermantel aufgeschoben werden kann. Bei diesem Wechsel der Mantelhülsen ist es üblicherweise erforderlich, ein Lager auszubauen oder so weit abzubauen, daß der eine Wellenzapfen des Formatzylinders von dem Lager freikommt oder aus diesem herausgehoben werden kann, wobei sodann üblicherweise auf den Formatzylinderzapfen ein Rohr aufgeschoben wird, das auf einem Bock abgestützt ist, um zu verhindern, daß der nur noch einendig in seinem Lager gehaltene Formatzylinder herabfällt. Die abgeschobene Mantelhülse befindet sich sodann zunächst auf dem den Formatzylinderkern stützenden Rohr, von dem es abgenommen werden muß, bevor die neue Formatzylinderhülse auf das Rohr geschoben wird, wobei auch während des Abnehmens und Aufschiebens der Hülse auf das Rohr der Formatzylinderkern in seiner im wesentlichen waagerechten Lage gehalten werden muß. Dieses bekannte Verfahren zum Austausch der Formatzylinderhülsen ist daher verhältnismäßig kompliziert und arbeitsaufwendig.In order to be able to convert a flexographic printing press to a new job as quickly as possible, it is known to put on a format or plate cylinder jacket consisting of a sleeve, which is exchanged for a new one only when a job is changed, on a format cylinder core that can be slightly conical. Replacing only the format cylinder jacket consisting of a sleeve now makes it necessary to remove only one bearing of the format cylinder so that the format cylinder jacket consisting of a sleeve can be removed from the format cylinder core and a new format cylinder jacket can be pushed on. When changing the casing sleeves, it is usually necessary to remove a bearing or to dismantle it so far that one shaft journal of the format cylinder is released from the bearing or can be lifted out of it, in which case a tube is usually pushed onto the format cylinder journal, which is placed on a trestle is supported to prevent the format cylinder, which is only held in one end in its bearing, from falling. The sheathed sleeve is then first of all on the tube supporting the format cylinder core, from which it must be removed before the new format cylinder sleeve is pushed onto the tube, while the sleeve of the format cylinder core is also substantially horizontal when the sleeve is removed and pushed onto the tube Location must be kept. This known method for exchanging the format cylinder sleeves is therefore relatively complicated and labor-intensive.

Bei einer aus der DE-C-891 396 bekannten Lagerung der eingangs angegebenen Art ist der Lagerbock als konische Scheibe ausgebildet und wird durch Spannelemente in einer komplementären konischen Öffnung der Maschinengestellwand gehalten. Das Lösen und Fixieren des Lagerbocks ist daher bei der bekannten Lagerung relativ aufwendig.In a bearing of the type specified in DE-C-891 396, the bearing block is designed as a conical disk and is held in a complementary conical opening of the machine frame wall by clamping elements. The loosening and fixing of the bearing block is therefore relatively expensive in the known storage.

Bei einer aus der FR-A-2 353 395 bekannten Lagerung für einen Formatzylinder wird durch eine besondere Abzugsvorrichtung ein Lager von einem Lagerzapfen des Formatzylinders in axialer Richtung vollständig abgezogen, während an dem das ungelöste Lager nach außen hin überragenden Zapfen ein den Formatzylinder in seiner waagerechten Lage haltendes Widerlager oder eine hydraulisch betätigte Zugeinrichtung angreift, so daß der Formatzylindermantel von dem an einem Achzapfen frei auskragend gehaltenen Formatzylinderkern abgezogen und durch einen anderen Mantel ersetzt werden kann. Bei dieser bekannten Vorrichtung ist nicht nur das vollständige Abziehen eines Lagers aufwendig, sondern das ungelöste Lager wird zusätzlich auch in unerwünschter Weise beim Wechsel des Formatzylindermantels hoch beansprucht, da dieses die vollen Reaktionskräfte aufnehmen muß. die sich aus der Abstützung des freien Endes des Lagerzapfens auf einem Widerlager oder an der hydraulischen Zugvorrichtung ergeben.In a bearing for a format cylinder known from FR-A-2 353 395, a bearing is completely withdrawn from a bearing journal of the format cylinder in the axial direction by means of a special pull-off device, while on the journal which projects outward from the undissolved bearing, the format cylinder in its horizontal position-holding abutment or a hydraulically operated pulling device attacks, so that the format cylinder jacket can be removed from the format cylinder core which is freely cantilevered on an axle journal and can be replaced by another jacket. In this known device, not only is the complete removal of a bearing complex, but the undissolved bearing is also undesirably stressed when changing the format cylinder jacket, since this has to absorb the full reaction forces. which result from the support of the free end of the bearing journal on an abutment or on the hydraulic pulling device.

Aufgabe der Erfindung ist es, eine Lagerung nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, die einen einfacheren und schnelleren Austausch des hülsenförmigen Formatzylindermantels gestattet.The object of the invention is to provide a bearing according to the preamble of claim 1, which allows easier and faster replacement of the sleeve-shaped format cylinder jacket.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of patent claim 1.

Bei der erfindungsgemäßen Lagerung wird zunächst der Formatzylinder im Bereich seines nicht zu lösenden Lagers in der Weise abgestützt, daß er auch ohne das zu lösende Lager frei auskragend in etwa waagerechter Lage gehalten wird. Anschließend wird das lösbare Lager auf seinem schlittenförmig verschiebbaren Tragteil so weit in axialer Richtung abgeschoben, daß es von dem Wellenzapfen des Formatzylinders freikommt und der Formatzylinder im Bereich des ungelösten Lagers nur noch von der Stützeinrichtung gehalten wird. Die inneren Enden der Führungen des Lagertragteils werden sodann von dem Maschinengestell oder dem Formatzylinderschlitten gelöst, so daß der Bügel mit den Führungen herausgeschwenkt werden kann und das Lager vollständig aus dem Bereich des Formatzylinders kommt. Der hülsenförmige Formatzylindermantel läßt sich sodann mit den üblichen Hilfsmitteln in axialer Richtung von dem Formatzylinderkern abziehen, ohne daß Lager- oder Stützteile im Wege wären.In the storage according to the invention, the format cylinder is first supported in the area of its non-detachable bearing in such a way that it is held in a cantilevered position in a cantilevered manner even without the bearing to be detached. Subsequently, the detachable bearing is pushed on its slide-shaped movable support part so far in the axial direction that it is released from the shaft journal of the format cylinder and the format cylinder in the area of the undissolved bearing is only held by the support device. The inner ends of the guides of the bearing support part are then released from the machine frame or the format cylinder slide, so that the bracket with the guides can be pivoted out and the bearing comes completely out of the area of the format cylinder. The sleeve-shaped format cylinder jacket can then be pulled off the format cylinder core in the axial direction with the usual aids, without bearing or support parts being in the way.

Nachdem der neue hülsenförmige Formatzylindermantel auf den Formatzylinderkern aufgeschoben und auf diesem befestigt ist, wird in umgekehrter Reihenfolge der Bügel wieder eingeschwenkt, so daß das gelöste Lager wieder mit dem Formatzylinder fluchtet. Nach Verriegelung der Führungen mit dem Formatzylinderschlitten bzw. dem Maschinengestell wird das gelöste Lager wieder auf den freien Wellenzapfen des Formatzylinders aufgeschoben und fixiert. Die Fixierung kann beispielsweise aus einem in eine entsprechende Ausnehmung des Tragteils einschiebbaren T-förmigen Kopf bestehen, der durch einen Exzenter mit dem Maschinengestell und dem Formatzylinderschlitten verspannbar ist.After the new sleeve-shaped format cylinder jacket has been pushed onto the format cylinder core and fastened on it, the bracket is pivoted back in in reverse order so that the detached bearing is again aligned with the format cylinder. After locking the guides with the format cylinder slide or the machine frame, the released bearing is pushed back onto the free shaft journal of the format cylinder and fixed. The fixation can consist, for example, of a T-shaped head which can be inserted into a corresponding recess in the supporting part and which can be clamped to the machine frame and the format cylinder slide by an eccentric.

Die Stützeinrichtung für den Formatzylinder besteht aus im Maschinengestell oder auf den Formatzylinderschlitten beidseits des ungelösten Lagers angeordneten hydraulischen Kolbenzylindereinheiten, von denen die Kolbenstange des inneren Zylinders mit einer gegen einen inneren Teil des Wellenzapfens des Formatzylinderkerns ausfahrbaren Stützschale und die Kolbenstange des äußeren Zylinders mit einem äußeren Teil des Wellenzapfens des Formatzylinders übergreifenden einziehbaren Stützjoch versehen sind, das die obere Begrenzung eines fensterartigen Ausschnitts eines Zugteils bildet. Der fensterartige Ausschnitt muß dabei eine so große Höhe aufweisen, daß im angehobenen Zustand des Zugteils der Formatzylinder während des Druckbetriebes behinderungsfrei in seine "Druckab"- Stellung gehoben werden kann.The support device for the format cylinder consists of hydraulic piston cylinder units arranged in the machine frame or on the format cylinder slide on both sides of the undissolved bearing, of which the piston rod of the inner cylinder with a support shell which can be extended against an inner part of the shaft journal of the format cylinder core and the piston rod of the outer cylinder with an outer part the retractable support yoke, which forms the upper boundary of a window-like section of a pulling part, is provided for the shaft journal of the format cylinder. The window-like The cut-out must have such a high height that the format cylinder can be lifted into its "print-off" position without hindrance during the printing operation when the pulling part is raised.

Ublicherweise sind Formatzylinder, insbesondere von Flexodruckmaschinen, auf Formatzylinderschlitten gelagert, so daß der Bügel mit den Führungen für das Tragteil des lösbaren Lagers das vordere Endstück des Formatzylinderschlittens bildet.Format cylinders, in particular from flexographic printing presses, are usually mounted on format cylinder slides, so that the bracket with the guides for the supporting part of the detachable bearing forms the front end piece of the format cylinder slide.

Das Tragteil kann über Kugelbüchsen auf zwei aus Rundstahl bestehenden Führungsstangen geführt sein.The supporting part can be guided over ball bushings on two guide rods made of round steel.

Die Führungsstangen sind zweckmäßigerweise mit axialen Bohrungen versehen, in denen zu deren Verriegelung Schraubbolzen angeordnet sind, die mit auf der Außenseite des Bügels abgestützten und mit Handgriffen versehenen Köpfen und an ihren vorderen Enden mit in den Formatzylinderschlitten einschraubbaren Gewindeteilen versehen sind.The guide rods are expediently provided with axial bores in which screw bolts are arranged for their locking, which are provided with heads supported on the outside of the bracket and provided with handles and at their front ends with threaded parts which can be screwed into the format cylinder slide.

In dem Maschinengestell 1 der Flexodruckmaschine ist der mit einem nicht dargestellten Antrieb versehene Druckzylinder 2 gelagert. Das Maschinengestell 1 ist mit etwa radialen Tragarmen bzw. Konsolen 3 versehen, auf denen Formatzylinderschlitten 4 längsverschieblich geführt sind, die beidseits mit Lagerböcken 5 für die Formatzylinder 6 versehen sind. Die Formatzylinderschlitten 4 sind mit Spindeln zum Heranfahren der Formatzylinder 6 an den Druckzylinder 2 versehen.The printing cylinder 2, which is provided with a drive (not shown), is mounted in the machine frame 1 of the flexographic printing press. The machine frame 1 is provided with approximately radial support arms or brackets 3, on which format cylinder slides 4 are guided in a longitudinally displaceable manner and which are provided on both sides with bearing blocks 5 for the format cylinders 6. The format cylinder slides 4 are provided with spindles for moving the format cylinders 6 to the impression cylinder 2.

Auf dem Formatzylinderschlitten 4 ist der Farbwerksschlitten 7 längsverschieblich geführt, der mit dem Farbauftragswerk und der in diesem gelagerten Farbauftragswalze 8 versehen ist.The inking unit slide 7, which is provided with the inking unit and the inking roller 8 mounted therein, is guided in a longitudinally displaceable manner on the format cylinder slide 4.

Zur Ausführung der "Druck-an"- und "Druck- ab"-Bewegungen sind die Lagerböcke 5 für die Formatzylinder mit eingearbeiteten Zylindern und mit mit Lippendichtungen versehenen Kolben versehen, wie sie beispielsweise in der DE-C-29 41 521 beschrieben sind.To carry out the "pressure-on" and "pressure-down" movements, the bearing blocks 5 for the format cylinders are provided with incorporated cylinders and with pistons provided with lip seals, as are described, for example, in DE-C-29 41 521.

Um zum Austausch der hülsenförmigen Formatzylindermäntel auf einfache und schnelle Weise einen eine Seite des Formatzylinders 6 lagernden Lagerbock 5 entfernen zu können, ist dieser in unten näher beschriebener Weise auf Führungen schlittenartig verschiebbar gelagert, wobei die Führungen mit einem bügelförmigen Tragteil 9 verbunden sind, das den vorderen Teil des Formatzylinderschlittens 4 bildet und um die Achse 10 von diesem wegschwenkbar ist.In order to be able to easily and quickly remove a bearing block 5 that supports one side of the format cylinder 6 in order to replace the sleeve-shaped format cylinder jackets, it is slidably mounted on guides in the manner described in more detail below, the guides being connected to a bow-shaped support part 9, which the forms the front part of the format cylinder slide 4 and can be pivoted away about the axis 10 thereof.

Aus Fig. 2 sind die nach oben gerichteten Schenkel 11, 12 der Konsole 3 ersichtlich, auf denen die Lagerböcke 13, 14 für die Formatzylinderlager 15, 16 angeordnet sind, wobei sich zwischen den Lagerböcken und den Lagern die Druckmittel-Kolben-Zylindereinheiten 17, 18 zum Ausführen der "Druck-an"- und "Druck-ab"-Bewegungen durch Anheben und Absenken der Lager 15, 16 befinden.From Fig. 2 the upward legs 11, 12 of the bracket 3 can be seen, on which the bearing blocks 13, 14 for the format cylinder bearings 15, 16 are arranged, the pressure medium-piston-cylinder units 17, between the bearing blocks and the bearings 18 for executing the "pressure-on" and "pressure-down" movements by raising and lowering the bearings 15, 16.

Der Formatzylinder 6 ist mit Wellenzapfen 20, 21 versehen, die in Gleitlagerbuchsen 22, 23 gelagert sind, die mit kugeligen Außenseiten versehen sind, die in entsprechenden Kugelschalen der Lagerböcke gehaltert sind.The format cylinder 6 is provided with shaft journals 20, 21 which are mounted in slide bearing bushes 22, 23 which are provided with spherical outer sides which are held in corresponding spherical shells of the bearing blocks.

Der Schenkel 11 der Konsole 3 ist beidseits mit Tragstücken 24, 25 versehen, an denen hydraulische Kolbenzylindereinheiten 26, 27 befestigt sind. Die Tragstücke 24, 25 können auch am Formatzylinderschlitten 4 befestigt sein. Die Kolbenstange 28 der Kolbenzylindereinheit 26 trägt an ihrem oberen Ende eine Stützschale 29, die zur Abstützung des Formatzylinders 6 von unten her gegen einen über einen Absatz verdichten Abschnitt 30 des Wellenzapfens des Formatzylinders 6 gefahren werden kann. Der äußere Abschnitt 31 des Wellenzapfens des Formatzylinders 6 ist gegenüber dem der Lagerung dienenden Abschnitt 20 über einen Absatz verjüngt und greift durch ein längliches Fenster 32 einesThe leg 11 of the bracket 3 is provided on both sides with support pieces 24, 25 to which hydraulic piston cylinder units 26, 27 are attached. The support pieces 24, 25 can also be attached to the format cylinder slide 4. The piston rod 28 of the piston-cylinder unit 26 carries at its upper end a support shell 29 which can be moved from below to support the format cylinder 6 against a section 30 of the shaft journal of the format cylinder 6 that compresses via a shoulder.

Der Lagerbock 14 ist mit zwei Bohrungen 46 versehen, in denen Kugelbüchsen durch Klemmringe gehaltert sind, die auf den Führungsstangen 43, 44 laufen.As can be seen from FIG. 3, the swivel bracket 41, which consists of an angled lever, is pivotably connected to the web 12 of the format cylinder slide 4 about the vertical hinge pin 40. In the angled leg 42 of the swivel bracket 41, the guides consisting of the rods 43, 44 are fastened parallel to one another. The opposite ends of the guide rods 43, 44 are connected to one another by the web 45. On the guide rods 43, 44, the bearing block 14 for the bearing 16 is guided in a longitudinally displaceable manner. The bearing block 14 is provided with two bores 46, in which ball bushings are held by clamping rings which run on the guide rods 43, 44.

Die Führungsstangen 43, 44 sind mit axialen Bohrungen versehen, die Schraubbolzen 48 durchsetzen. Die äußeren Enden der Schraubbolzen 48 sind mit Kopfstücken 49 verbunden, die sich auf den Außenseiten des Schenkels 42 des Schwenkbügels 41 abstützen und mit Handgriffen 50 versehen sind. Die inneren Enden der Schraubbolzen 48 sind mit Gewinden 51 versehen, die in entsprechende Gewindebohrungen eines Wandteils 52 des Stegteils 12 des Formatzylinderschlittens 4 einschraubbar sind.The guide rods 43, 44 are provided with axial bores which pass through the bolts 48. The outer ends of the bolts 48 are connected to head pieces 49, which are supported on the outer sides of the leg 42 of the swivel bracket 41 and are provided with handles 50. The inner ends of the bolts 48 are provided with threads 51 which in Corresponding threaded bores of a wall part 52 of the web part 12 of the format cylinder slide 4 can be screwed in.

Wie aus Fig. 2 ersichtlich ist, weist der Schwenkbügel 41 zwei gegabelte Lagerschenkel 54, 55 auf, die ein stegförmiges Lagerteil 56 des Formatzylinderschlittens 4 einfassen.As can be seen from FIG. 2, the swivel bracket 41 has two forked bearing legs 54, 55, which enclose a web-shaped bearing part 56 of the format cylinder slide 4.

In Fig. 3 ist die ausgeschwenkte Stellung des Schwenkbügels 41 mit den Führungsstangen 43, 44 strichpunktiert eingezeichnet.In Fig. 3, the pivoted-out position of the swivel bracket 41 with the guide rods 43, 44 is shown in dash-dotted lines.

Zum Wechsel des hülsenförmigen Formatzylindermantels werden zunächst die Stützschale 29 und das Joch 35 des Zugteils 33 in ihre aus Fig. 2 ersichtlichen Stützstellungen gefahren. In dieser Stützstellung wird der Formatzylinder 6 allein an seinem linken Wellenzapfen an dessen Abschnitten 30, 31 gehalten, so daß nach Entfernung des Lagers 16 der Formatzylinder 6 in seiner Lage beharrt.To change the sleeve-shaped format cylinder jacket, the support shell 29 and the yoke 35 of the tension member 33 are first moved into their support positions shown in FIG. 2. In this supporting position, the format cylinder 6 is held on its left shaft journal at its sections 30, 31, so that after the bearing 16 has been removed, the format cylinder 6 remains in its position.

Zum Entfernen des Lagers 16 wird zunächst die nicht dargestellte Arretierung oder Verriegelung des Lagerbocks 14 mit dem Steg 12 des Formatzylinderschlittens 4 gelöst. Nach diesem Lösen und nach einer eventuellen Lockerung der Lagerschalen des Lagers 16 läßt sich das Lager 16 durch axiales Bewegen des Lagerbocks 14 von dem Wellenzapfen 21 abziehen. Dabei wird der Lagerbock 14 so weit nach außen gezogen, daß er sich in der Nähe des Schenkels 42 des Schwenkbügels 41 befindet. Anschließend werden über die Handgriffe 50 die Schraubbolzen 48 gedreht, bis diese aus dem Stegteil 52 des Formatzylinderschlittens 4 herausgeschraubt sind. In dieser Lage läßt sich der Schwenkbügel 41 mit dem Lagerbock 14, der Kolbenzylindereinheit 18 und dem Lager 16 in die aus Fig. 3 ersichtliche strichpunktierte Stellung verschwenken. In dieser kann nun in üblicher Weise der hülsenförmige Formatzylindermantel von dem Formatzylinder 6 zum Austausch gegen einen anderen abgezogen werden.To remove the bearing 16, the not shown locking or locking of the bearing block 14 with the web 12 of the format cylinder slide 4 is first released. After this loosening and after a possible loosening of the bearing shells of the bearing 16, the bearing 16 can be pulled off the shaft journal 21 by axially moving the bearing block 14. The bearing block 14 is pulled out so far that it is in the vicinity of the leg 42 of the swivel bracket 41. The screw bolts 48 are then rotated via the handles 50 until they are screwed out of the web part 52 of the format cylinder slide 4. In this position, the swivel bracket 41 with the bearing block 14, the piston-cylinder unit 18 and the bearing 16 can be pivoted into the dash-dotted position shown in FIG. 3. In this, the sleeve-shaped format cylinder jacket can now be removed from the format cylinder 6 for exchange with another in the usual way.
