Description

Die Erfindung betrifft eine Vorrichtung zum paßgerechten Ausrichten eines Gummituches auf einem Gummituch- bzw. Formzylinder für ausgesparte Inline-Lackierung in einer Rotationsdruckmaschine nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for aligning a blanket on a blanket or forme cylinder for recessed inline coating in a rotary printing press according to the preamble of patent claim 1.

Eine der bekanntesten Ausführungen zum Spannen eines Gummituches sieht vor, beide Enden desselben mit Klemmeinrichtungen zu versehen, die in Nuten zweier Spannspindeln eingreifen. Das Spannen des Gummituches erfolgt dabei durch Verdrehen der Spannspindeln über Schneckentrieb mittels Drehmomentschlüssel. Die Befestigung der Gummituchenden mit den Klemmeinrichtungen erfolgt, indem das Gummituch zwischen Klemmleisten verschraubt wird. Die Klemmleisten werden in den Nuten der Spannwellen durch Formverbindung gehalten. Für ausgesparte Inline-Lackierung, z.B. für lackfreie Klebelaschen, wird vorzugsweise bei der direkten Lackiermethode ein Offset-Gummituch benötigt, bei dem an den nicht zu lackierenden Stellen die oberste Gummituchschicht entfernt worden ist. Ein so präpariertes Tuch kann auch bei der indirekten Lackiermethode eingesetzt werden, wenn ein Plattenzylinder vollflächig mit Dispersionslack auf wässriger Basis eingewalzt wird. Bei genauen Arbeiten wird die Lage der nicht zu lackierenden, d.h. auszuschneidenden Partien des zum Lackieren eingesetzten Gummituches so hergestellt, daß ein Farbabklatsch der die Anhaltslinien liefernden Farbform übertragen durch den Bedruckstoff, durch Abdruck auf das trockene Lacktuch aufgebracht wird. Das Ausschneiden der entsprechenden Stelle in der Maschine ist zeitaufwendig und verlängert die Rüstzeit. Auch das Ausspannen des Gummituches, nach dem es den Farbklatsch erhalten hat, um es zeitlich parallel zum kompletten Einrichten der Farbformen der inline-laufenden Druckmaschine auszuschneiden, ist, weil es erneut eingespannt werden muß, immer noch zeitaufwendig.One of the best-known designs for tensioning a rubber blanket provides for both ends of the same to be provided with clamping devices which engage in grooves in two tensioning spindles. The blanket is tensioned by turning the tensioning spindles via worm gear using a torque wrench. The G ummituchenden with the clamping devices is done by screwing the rubber blanket between terminal strips. The tensioning shafts are lemm afford the K held by molding compound in the grooves. For recessed inline painting, eg for paint-free adhesive flaps, an offset rubber blanket is preferably required for the direct painting method, in which the top layer of rubber blanket has been removed from the areas that are not to be painted. A cloth prepared in this way can also be used for the indirect painting method if a plate cylinder is rolled over the entire surface with water-based dispersion paint. At precise work, the situation is the non-prepared to be painted, that is to be cut out parts of the rubber blanket used for varnishing so that a color imitation of the stop supplying lines F is transmitted arbform applied by the material to be printed, by print on the dry coating blanket. Cutting out the corresponding point in the machine is time-consuming and extends the set-up time. Unclamping the rubber blanket after it has received the ink gossip in order to cut it out in parallel with the complete setup of the color forms of the inline printing press is still time-consuming because it has to be re-clamped.

Aufgabe der Erfindung ist es, eine Vorrichtung zu schaffen, bei der beim Einpsannen eines so präparierten Gummituches der aufwendige Einrichtevorgang entfällt und zugleich die Möglichkeit besteht, eine Nachjustierung des Gummituches in axialer und in Umfangsrichtung vorzunehmen.The object of the invention is to provide a device in which, when a rubber blanket prepared in this way is clamped in, the complex setup process is dispensed with and at the same time there is the possibility of readjusting the rubber blanket in the axial and circumferential directions.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale ds ersten Patentanspruches. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, der Zeichnung und der Beschreibung.This object is achieved by the characterizing features of the first claim. Further developments of the invention result from the subclaims, the drawing and the description.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß durch die geschaffene Orientierungshilfe das paßgerechte Ausrichten eines Gummituches für ausgesparte Inline-Lackierung auf einem Gummituch- bzw. Formzylinder ohne Umfangs- und Seitenregister wesentlich erleichtert wird. Zum Erhalten einer paßgerechten Lackierung erübrigt sich praktisch das aufwendige Justieren, obwohl das System ein Ausrichten weiterhin zuläßt. Dadurch sind Korrekturen sowohl in Umfangsrichtung als auch in axialer Richtung möglich, z.B. wenn das Gummituch nach einer größeren Zahl von Lackierungen nachgespannt werden muß bzw. zum Ausgleich aufgetretener Paßungenauigkeiten nachjustiert werden muß, um die exakte Lage der zu lackierenden Stellen zur Farbform herzustellen.The advantages achieved by the invention are, in particular, that the alignment aid created makes it much easier to align a rubber blanket for recessed inline painting on a rubber blanket or forme cylinder without circumferential and side registers. In order to obtain a paint that matches the fit, there is practically no need for complex adjustments, although the system still allows alignment. This enables corrections both in the circumferential direction and in the axial direction, e.g. if the rubber blanket has to be retightened after a large number of varnishes or has to be readjusted to compensate for inaccuracies in fit, in order to produce the exact position of the areas to be varnished in relation to the color form.

In einer achsparallelen Grube 1 des Gummituch- bzw. Formzylindes 2 sind zwei Spannspindeln 3, 4 angeordnet, die in Stirnwänden 9 des Gummituch- bzw. Formzylinders 2 drehbar gelagert sind. Jede Spannspindel 3, 4 trägt eine Klemmeinrichtung 5, 6 für die Gummituchenden 7, 8 das Gummituches 26. Das Spannen des Gummituches 26 erfolgt durch Verdrehen der Spannspindeln 3 bzw. 4 über einen Schneckentrieb, z.B. durch Verdrehen der Spannspindel 3 über den Schneckentrieb 11, siehe Fig. 9. In bekannter Weise sind ferner ein Grubenwandsteg 10, eine Grubenabdeckung 28 und eine Halterung 27 für Unterlagebogen vorgesehen.In an axially parallel pit 1 of the blanket or form cylinder 2, two clamping spindles 3, 4 are arranged, which are rotatably mounted in end walls 9 of the blanket or form cylinder 2. Each tensioning spindle 3, 4 carries a clamping device 5, 6 for the rubber blanket ends 7, 8 of the rubber blanket 26. The tensioning of the rubber blanket 26 is carried out by turning the tensioning spindles 3 and 4 via a worm drive, e.g. by rotating the clamping spindle 3 via the worm drive 11, see FIG. 9. In a known manner, a pit wall web 10, a pit cover 28 and a holder 27 for supporting sheets are also provided.

Gemäß der Erfindung werden an jeder Klemmeinrichtung 5, 6 Paßeinrichtungen vorgesehen, die jeweils zwei axialen Abstand aufweisende, radial gerichtete und unter der Zylindermantelfläche in der unteren Klemmeinrichtung 5 bzw. 6 liegende Registerbolzen 12, 13 aufweisen, mit denen je zwei in den zugeordneten Gummituchenden 7, 8 vorgesehene Ausnehmungen 14, 15 mit rechteckiger Form bzw. mit halbkreisförmiger Rundung genau passend zusammenwirken. Die Registerbolzen 13 sind in tangentialer Richtung beidseitig abgeflacht. Dadurch können Auswölbungen im Gummituch beim festen Einspannen außerhalb der Druckmaschine an beiden Gummituchenden 7, 8 ausgeglichen werden. Gleichzeitig ist die Stellung der Gummituchenden 7, 8 zu den Klemmeinrichtungen 5, 6 genau festgelegt. Zur Beobachtung der Anlage der Registerbolzen 12, 13 und Ausnehmungen 14, 15 sind in den Klemmeinrichtungen 5, 6 Ausschnitte 28 in der oberen Klemmleiste vorgesehen. Die Klemmeinrichtung 5 für das vordere Gummituchende 7 ist in der Nullage in Umfangsrichtung mittels einer Markierung 24 am vorderen Gummituchende 7 und einer zugeordneten Markierung auf dem Formzylinder 2 fixierbar (Fig. 1, 6 bis 8).According to the invention, 5, 6 fitting devices are provided on each clamping device, the two axially spaced, radially directed and under the cylinder jacket Surface in the lower clamping device 5 or 6 have register bolts 12, 13, with which two recesses 14, 15 provided in the associated rubber blanket ends 7, 8 cooperate with each other with a rectangular shape or with a semicircular curve. The register bolts 13 are flattened on both sides in the tangential direction. As a result, bulges in the rubber blanket can be compensated for on both rubber blanket ends 7, 8 when firmly clamped outside the printing press. At the same time, the position of the rubber blanket ends 7, 8 relative to the clamping devices 5, 6 is precisely defined. To observe the contact of the register bolts 12, 13 and recesses 14, 15, cutouts 28 are provided in the upper clamping strip in the clamping devices 5, 6. The clamping device 5 for the front blanket end 7 can be fixed in the zero position in the circumferential direction by means of a marking 24 on the front blanket end 7 and an associated marking on the forme cylinder 2 (FIGS. 1, 6 to 8).

Die Nullage der Klemmeinrichtung 5 ist in einer anderen in der Zeichnung nicht dargestellten Ausführungsform auch dadurch erreichbar, daß die Spannspindel 3 in Umfangsrichtung an einem justierenden Anschlag positionierbar ist.In another embodiment, not shown in the drawing, the zero position of the clamping device 5 can also be achieved in that the clamping spindle 3 can be positioned in the circumferential direction on an adjusting stop.

Die Klemmeinrichtungen 5, 6 sind entweder mit den verdrehbaren Spannspindeln 3, 4 mittels Stelleinrichtung 16 axial verschiebbar im Gummituch- bzw. Formzylinder 2 angeordnet. Hierzu ist gemäß Fig. 5 die Klemmeinrichtung 5 bzw. 6 mittels Klemmschrauben 23 mit der Spannspindel 3 bzw. 4 über Gewindering 21 bzw. 22 axial verschiebbar.The clamping devices 5, 6 are either axially displaceable in the blanket or forme cylinder 2 with the rotatable clamping spindles 3 , 4 by means of the adjusting device 16. 5, the clamping device 5 or 6 is axially displaceable by means of clamping screws 23 with the clamping spindle 3 or 4 via the threaded ring 21 or 22.

Die Klemmeinrichtungen 5, 6 können auch auf den Spannspindeln 3, 4 axial verschiebbar angeordnet sein. Hierzu ist gemäß Fig. 3 und 4 an den Spannspindeln 4, 5 jeweils ein Lagerbock 18 befestigt, in dem eine Verstellschraube 17 angeordnet ist, die einen Mitnehmer 20 trägt, der mittels Stellring 19 exakt positioniert ist und mit der unteren Klemmleiste der Klemmeinrichtungen 5, 6 formschlüssig verbunden ist. Durch Verdrehen der Verstellschraube 17 im Lagerbock 18 ist die Klemmeinrichtung 5 bzw. 6 auf den Spannspindeln 3 bzw. 4 axial veschiebbar.The clamping devices 5, 6 can also be arranged axially displaceably on the clamping spindles 3, 4. 3 and 4, a bearing block 18, in which an adjusting screw 17 is arranged, is fastened to the clamping spindles 4, 5 is, which carries a driver 20, which is positioned exactly by means of the collar 19 and is positively connected to the lower terminal block of the clamping devices 5, 6. By turning the adjusting screw 17 in the bearing block 18, the clamping device 5 or 6 on the clamping spindles 3 or 4 is axially displaceable.

Ein Nachjustieren in Umfangsrichtung erfolgt in bekannter Weise durch Verdrehen der Spannspindeln 3, 4 über den zugeordneten Schneckentrieb.Readjustment in the circumferential direction is carried out in a known manner by turning the clamping spindles 3, 4 via the assigned worm drive.

Die Bedienung der Vorrichtung wird wie folgt vorgenommen: Zunächst werden außerhalb der Druckmaschine die mit den Ausnehmungen 14, 15 versehenen Gummituchenden 7, 8 zwischen den Klemmleisten der Klemmeinrichtung 5, 6 eingelegt, bis die Ausnehmungen 14, 15 mit den Registerbolzen 12, 13 zur Anlage kommen. Danach werden die Klemmschienen der Klemmeinrichtungen 5, 6 mittels der Klemmschrauben 29 fest verbunden. Anschließend werden die Klemmeinrichtungen 5, 6 mit dem Gummituch 26 in den Gummituch- bzw. Formzylinder 2 eingesetzt und das Gummituch 26 wird vorsichtig gespannt. Danach wird ein Farbabklatsch der die Anhaltslinien für die ausgesparte Inline-Lackierung liefernden Farbform, übertragen durch den Bedruckstoff, durch Abdruck auf das tockene Lacktuch aufgebracht. Außerdem werden am vorderen Gummituchende 7 die Markierungen 24 angebracht, die mit den Markierungen am Gummituch- bzw. Formzylinder 2 übereinstimmen. Zum Ausschneiden der nicht zu lackierenden Stellen wird das Gummituch 26 mit den Klemmeinrichtungen 5, 6 aus der Druckmaschine herausgenommen, danach wieder eingesetzt und erneut gespannt. Dabei ist sofort eine richtige Justierung gegeben, wenn die Markierungen 24 des Gummituches 26 am vorderen Gummituchende 7 mit den zugeordneten Markierungen auf dem Formzylinder 2 in Ubereinstimmung gebracht wurden und ggf. eine Probelackierung erfolgt ist. Sollten Paßungenauigkeiten auftreten oder nach einer größeren Anzahl von Lakkierungen ein Nachspannen des Gummituches 26 erforderlich sein, kann dies in axialer Richtung mittels, der Stelleinrichtungen 16 gemäß Fig. 5 bzw. Fig. 3 und 4 sowie in Umfangsrichtung mittels der einzeln verdrehbaren Spannspindeln 3, 4 über Schneckentrieb 11 erfolgen.The device is operated as follows: First, outside of the printing press, the rubber blanket ends 7, 8 provided with the recesses 14, 15 are inserted between the terminal strips of the clamping device 5, 6 until the recesses 14, 15 with the register bolts 12, 13 come to rest come. Then the clamping rails of the clamping devices 5, 6 are firmly connected by means of the clamping screws 29. The clamping devices 5, 6 with the rubber blanket 26 are then inserted into the rubber blanket or forme cylinder 2 and the rubber blanket 26 is carefully stretched. Afterwards, a color swipe of the color form, which provides the reference lines for the recessed inline coating, transferred by the printing material, is applied to the dry coating cloth by printing. In addition, the markings 24 are attached to the front blanket end 7, which correspond to the markings on the blanket or forme cylinder 2. To cut out the areas that are not to be painted, the rubber blanket 26 with the clamping devices 5, 6 is removed from the printing press, then reinserted and stretched again. A correct adjustment is immediately given when the markings 24 of the rubber blanket 26 on the front rubber blanket end 7 with the associated markings on the Forme cylinder 2 have been brought into line and if necessary a test coating has taken place. If there is an inaccuracy of fit or after a large number of lacquering, it is necessary to retighten the rubber blanket 26, this can be done in the axial direction by means of the adjusting devices 16 according to FIGS. 5 or 3 and 4 and in the circumferential direction by means of the individually rotatable tensioning spindles 3, 4 via worm gear 11.
