Description

Die Erfindung betrifft eine Vorrichtung mit einem in einem Zylinderkanal eines Plattenzylinders einer Rotationsdruckmaschine axial verstellbar angeordneten Registerstift gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device with a register pin arranged axially adjustable in a cylinder channel of a plate cylinder of a rotary printing press according to the preamble of claim 1.

Bei Rotationsdruckmaschinen mit mehreren hintereinandergeschalteten Druckwerken tritt das Problem auf, daß sich die bedruckte Papierbahn in Abhängigkeit von ihrer Beschaffenheit und Feuchtmittelaufnahme während des Druckens in ihrer Breite verändert. Diese Breitenänderung kann von Druckwerk zu Druckwerk unterschiedlich sein.In rotary printing presses with several printing units connected in series, the problem arises that the width of the printed paper web changes depending on its nature and dampening solution absorption during printing. This change in width can vary from printing unit to printing unit.

Durch die DE-OS 35 45 297 ist es bereits bekannt, die Registerstifte für zwei nebeneinander auf einem Plattenzylinder angeordnete Druckplatten mittels einer Seitenstellvorrichtung axial zu verschieben. Zu diesem Zweck sind die Registerstifte jeweils mittels einer Stellstange bzw. einem Stellrohr über Gewinde unterschiedlicher Steigung mit einer gemeinsamen Stellschraube verbunden.From DE-OS 35 45 297 it is already known to axially shift the register pins for two printing plates arranged side by side on a plate cylinder by means of a side adjusting device. For this purpose, the register pins are each connected to a common set screw by means of an adjusting rod or an adjusting tube via threads of different pitch.

Es ist bei der DE-OS 35 45 297 von Nachteil, daß die Registerstifte für zwei nebeneinander angeordnete Druckplatten immer gleichzeitig und mit festgelegter Übersetzung verstellt werden. Eine die Druckqualität erhöhende individuelle Verstellung des einzelnen Registerstiftes ist nicht möglich. Eine Verbindungsstange zwischen Registerstift und Stellschraube weist insbesondere für die in der Nähe der Zylindermitte vorgesehenen Registerstifte eine sehr große Länge auf, so daß zusätzliche Führungen vorgesehen werden müssen, damit die Registergenauigkeit der Registerstifte mit zunehmendem Abstand von der Stellschraube nicht leidet. Die vorgesehene Stelleinrichtung ist konstruktiv aufwendig, d.h. sie benötigt viel Platz und erfordert hohe Herstellungskosten.It is disadvantageous in DE-OS 35 45 297 that the register pins for two printing plates arranged side by side are always adjusted simultaneously and with a fixed translation. An individual adjustment of the individual register pin which increases the print quality is not possible. A connecting rod between the register pin and set screw points in particular for those in the Provided near the cylinder center register pins on a very long length, so that additional guides must be provided so that the register accuracy of the register pins does not suffer with increasing distance from the set screw. The proposed actuating device is structurally complex, ie it takes up a lot of space and requires high manufacturing costs.

Aus der DE-OS 20 45 953 ist es bekannt, in einem Plattenzylinderkanal ein Anschlagstück vorzusehen, an dem eine Druckplatte einseitig angelegt wird. Das Anschlagstück ist als Spannbüchse ausgeführt.From DE-OS 20 45 953 it is known to provide a stop piece in a plate cylinder channel on which a pressure plate is applied on one side. The stop piece is designed as a clamping bush.

Es ist bei dem Anschlagstück nach der DE-OS 20 45 953 von Nachteil, daß dieses nur als einseitiger Anschlag dient. Durch diese Maßnahme ist eine Druckplatte nur gegen seitliches Verschieben in einer Richtung gesichert. Ein notwendiges seitliches Fixieren nach beiden Seiten hin ist nicht möglich. Ein Einsatz des Anschlagstückes als Registerstift ist ebenfalls nicht möglich, da das als Spannbüchse ausgeführte Anschlagstück beim Verspannen seine äußere Form verändert, hierdurch wird ein vor dem Fixieren festgesetztes Maß beim Fixieren wieder verändert.It is a disadvantage of the stop piece according to DE-OS 20 45 953 that this only serves as a one-sided stop. With this measure, a pressure plate is only secured against lateral displacement in one direction. Necessary lateral fixation on both sides is not possible. It is also not possible to use the stop piece as a register pin, since the stop piece designed as a clamping sleeve changes its outer shape when it is clamped, as a result of which a dimension fixed before fixing is changed again when fixing.

Die US-A-38 99 972 zeigt eine gattungsgemäße Vorrichtung mit einem in einem Zylinderkanal eines Plattenzylinders einer Rotationsdruckmaschine angeordneten verstellbaren Registerstift. Der Registerstift ist axial verstellbar und besteht aus einem Registerteil und einem Befestigungsteil. Das Registerteil ist zum Aufnehmen eines zur Registerung dienenden Schlitzes einer Druckplatte. Das Befestigungsteil weist axial ausgerichtete Langlöcher zum Befestigen des Registerstiftes in axial verlaufenden Aussparungen des Plattenzylinders auf.US-A-38 99 972 shows a generic device with an adjustable register pin arranged in a cylinder channel of a plate cylinder of a rotary printing press. The register pin is axially adjustable and consists of a register part and a fastening part. The register part is for receiving a slit of a printing plate used for registration. The fastening part faces axially aligned slots for attaching the register pin in axially extending recesses of the plate cylinder.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mittels der vorgesehene Registerstifte am Plattenzylinder einer Rotationsdruckmaschine einzeln axial verstellt und fixiert werden können.The invention has for its object to provide a device by means of the provided register pins on the plate cylinder of a rotary printing press can be individually axially adjusted and fixed.

Die Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Anspruchs 1 gelöst.The object is achieved by the characterizing part of claim 1.

Der Vorteil der Erfindung liegt darin, daß jede Druckplatte individuell seitlich ausgerichtet werden kann, wobei es zu diesem Zweck nicht notwendig ist, die gesamte Druckplatteneinrichtung zu verschieben. Die erfindungsgemäße Vorrichtung kann sowohl an Plattenzylindern mit Schmitzringen als auch an Plattenzylindern ohne Schmitzringe eingesetzt werden. Die Vorrichtung ist konstruktiv einfach aufgebaut, kostengünstig herstellbar und leicht zu handhaben. Eine Verstellung und Fixierung des Registerstiftes kann mit einem einzigen Werkzeug erfolgen.The advantage of the invention is that each printing plate can be individually laterally aligned, for which purpose it is not necessary to move the entire printing plate device. The device according to the invention can be used both on plate cylinders with bearer rings and on plate cylinders without bearer rings. The device is structurally simple, inexpensive to manufacture and easy to use. The register pin can be adjusted and fixed with a single tool.

Die Einsatzleiste 3 ist lösbar am Plattenzylinder 2 befestigt. Es können im Bedarfsfall eine oder mehrere Druckplatten 7 nebeneinander an jeweils einer Einsatzleiste 3 am Plattenzylinder 2 angeordnet werden. Zu diesem Zweck ist in der Mitte der jeweils vorgesehenen Druckplatte 7 eine Aussparung 9 in Form einer Nut in der Einsatzleiste 3 vorgesehen.1 shows a conventional cylinder channel 1 of a plate cylinder 2 of a rotary printing press. In the cylinder channel 1, an insert bar 3 is arranged, each carrying a reversible device 4, 6 for fixing and tensioning a pressure plate 7. The insert bar 3 is releasably attached to the plate cylinder 2. If necessary, one or more printing plates 7 can be arranged next to one another on an insert bar 3 on the plate cylinder 2. For this purpose, a recess 9 in the form of a groove in the insert strip 3 is provided in the middle of the pressure plate 7 provided.

In der Aussparung 9 ist ein Registerstift 11 axial verschiebbar angeordnet. Der Registerstift 11 besteht aus einem Befestigungsteil 12 und einem fest damit verbundenen Registerteil 13. Das Befestigungsteil 12 ist am Grund 14 der Einsatzleiste 3 festsetzbar angeordnet. Zu diesem Zweck weist das Befestigungsteil 12 ein erstes Ende 16 mit einem Langloch 17 auf und ein zweites Ende 18 ebenfalls mit einem Langloch 19 und einem weiteren durchgehenden Langloch 21 auf. Die Langlöcher 17, 19 dienen der Befestigung des Registerstiftes 11 und sind in axialer Richtung des Plattenzylinders 2 angeordnet. Das Langloch 21 dient der axialen Verstellung des Registerstiftes 11 in der Aussparung 9 der Einsatzleiste 3 und ist um 90° versetzt zu den Langlöchern 17, 19, in Umfangsrichtung des Plattenzylinders 2 angeordnet. Die Langlöcher 17, 19 weisen jeweils einen Absatz 22; 23 auf, auf welchen sich jeweils der Kopf eines Befestigungsmittels 24, 26, z. B. einer Befestigungsschraube 24, 26 abstützt. Unterhalb der Langlöcher 17, 19 ist mit diesen in einer Flucht liegend jeweils eine Gewindebohrung 27; 28 in der Einsatzleiste 3 vorgesehen, in welche jeweils ein Gewinde der Befestigungsschrauben 24, 26 eingreift.In the recess 9, a register pin 11 is axially displaceable. The register pin 11 consists of a fastening part 12 and a register part 13 which is firmly connected thereto. For this purpose, the fastening part 12 has a first end 16 with an elongated hole 17 and a second end 18 also with an elongated hole 19 and a further continuous elongated hole 21. The elongated holes 17, 19 are used to fasten the register pin 11 and are arranged in the axial direction of the plate cylinder 2. The elongated hole 21 is used for the axial adjustment of the register pin 11 in the recess 9 of the insert strip 3 and is offset by 90 ° to the elongated holes 17, 19 in the circumferential direction of the plate cylinder 2. The elongated holes 17, 19 each have a shoulder 22; 23 on which the head of a fastener 24, 26, z. B. a mounting screw 24, 26 supports. Below the slots 17, 19 is in alignment with them each lying a threaded bore 27; 28 is provided in the insert strip 3, in each of which a thread of the fastening screws 24, 26 engages.

Unterhalb des Langlochs 21 ist mit diesem in einer Flucht angeordnet eine Bohrung 29 in der Einsatzleiste 3 vorgesehen. In der Rohrung 29 ist drehbar gelagert ein Exzenterbolzen 31 angeordnet, der ein exzentrisch zu seiner Achse 32 angeordnetes Stellmittel 33, z. B. einen Zapfen 33 aufweist. Der Zapfen 33 greift in das Langloch 21 ein. Der Zapfen 33 weist ein von oben zugängliches Sechskantloch 34 auf, und ist mit dem gleichen Werkzeug wie die Befestigungsschrauben 24, 26 betätigbar.Below the elongated hole 21, a bore 29 is provided in the insert bar 3, arranged in alignment therewith. In the piping 29, an eccentric bolt 31 is rotatably mounted, which has an adjusting means 33, e. B. has a pin 33. The pin 33 engages in the elongated hole 21. The pin 33 has a hexagon hole 34 accessible from above and can be actuated with the same tool as the fastening screws 24, 26.

Zur axialen Verstellung des Registerstiftes 11 werden zunächst die Befestigungsschrauben 24, 26 gelöst, daraufhin wird über das Sechskantloch 34 der Exzenterbolzen 31 verschwenkt. Hierbei greift der Zapfen 33 an einer Flanke des Langlochs 21 an und drückt den Registerstift 11 je nach Drehrichtung axial in die gewünschte Position, in welcher der Registerstift 11 mittels der Befestigungsschrauben 24, 26 am Grund 14 der Einsatzleiste 3 befestigt wird.For the axial adjustment of the register pin 11, the fastening screws 24, 26 are first loosened, then the eccentric pin 31 is pivoted via the hexagon hole 34. Here, the pin 33 engages on a flank of the elongated hole 21 and, depending on the direction of rotation, axially presses the register pin 11 into the desired position in which the register pin 11 is fastened to the base 14 of the insert strip 3 by means of the fastening screws 24, 26.

Zur Feststellung des Verstellmaßes kann der Zapfen 33 eine Markierung 36 und das Befestigungsteil 12 eine Skala 37 aufweisen. Es ist selbstverständlich auch möglich, eine Lehre zwischen eine Bezugsseite 38 eines Anschlagstückes 39 und den Befestigungsteil 12 des Registerstiftes 11 einzubringen. Das Anschlagstück 39 ist in der Aussparung 9 mittels eines Kegelstiftes 40 und einer Befestigungsschraube 48 an der Einsatzleiste 3 befestigt.To determine the adjustment dimension, the pin 33 can have a marking 36 and the fastening part 12 can have a scale 37. It is of course also possible to introduce a gauge between a reference side 38 of a stop piece 39 and the fastening part 12 of the register pin 11. The stop piece 39 is fastened in the recess 9 by means of a taper pin 40 and a fastening screw 48 on the insert strip 3.

Das Registerteil 13 des Registerstiftes 11 weist im Schnitt nach Fig. 1 eine T-Form auf, bei dem die zwischen waagerechtem Oberteil 41 und senkrechtem Unterteil 42 gebildeten Ecken den Einrichtungen 4, 6 zum Fixieren und Spannen angepaßt gerundet ausgebildet sind.
