Description

Die Erfindung betrifft eine Vorrichtung mit einem in einem Zylinderkanal eines Plattenzylinders einer Rotationsdruckmaschine verstellbaren Registerstiftes gemäß dem Oberbegriff des Anspruches.The invention relates to a device with a register pin adjustable in a cylinder channel of a plate cylinder of a rotary printing press according to the preamble of the claim.

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.
Es ist hier jedoch 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 bei den in der Nähe der Zylindermitte angeordneten Registerstiften 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.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.
However, it is disadvantageous here 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 in the Arranged 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.

Die GB-A-22 27 455 zeigt eine gattungsgemäße Vorrichtung mit einem in einem Zylinderkanal eines Plattenzylinders einer Rotationsdruckmaschine angeordneten axial verstellbaren Registerstift. Der Registerstift hat ein Befestigungsteil und ein Registerteil und greift nur in einen Schlitz eines einzigen Endes der Druckplatte ein. Für beide Enden der Druckplatte müssen also je ein verstellbares Registerteil vorgesehen werden.GB-A-22 27 455 shows a generic device with an axially adjustable register pin arranged in a cylinder channel of a plate cylinder of a rotary printing press. The register pin has a fastening part and a register part and only engages in a slot of a single end of the pressure plate. An adjustable register part must therefore be provided for each end of the pressure plate.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mittels der ein axial verstellbarer Registerstift am Plattenzylinder einer Rotationsdruckmaschine einzeln fixiert werden kann.The invention has for its object to provide a device by means of which an axially adjustable register pin on the plate cylinder of a rotary printing press can be fixed individually.

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

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.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.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden beschrieben.An embodiment of the invention is shown in the drawings and is described below.

Der Registerstift 11 hat im Schnitt nach Fig. 2 die Form eines auf dem Kopf liegenden T's und weist einen Befestigungsteil 24 und ein Registerteil 26 auf. Das Befestigungsteil 24 ist auf dem Grund 18 der Einsatzleiste 3 axial verschiebbar angeordnet, wobei ein erstes Ende 27 des Befestigungsteils 24 in die Führung 23 eingreift und ein zweites Ende 28 in die Führung 19 eingreift.The register pin 11 has the section of FIG. 2 in the form of a T lying on its head and has a fastening part 24 and a register part 26. The fastening part 24 is arranged axially displaceably on the base 18 of the insert strip 3, a first end 27 of the fastening part 24 engaging in the guide 23 and a second end 28 engaging in the guide 19.

 . 1 mm) between the projections 17, 22. Seen in the circumferential direction, the side walls of the recess 9 form a guide in the insert bar, which prevents the register pin 11 from being displaced in the circumferential direction of the plate cylinder 2. The register pin 11 has in each end 27, 28 of the fastening part 24 in each case a continuous threaded bore 29; 31 on. The threaded bores 29, 31 are each aligned with an elongated hole 32 provided in the projections 17, 22; 33.

Die Langlöcher 32, 33 erlauben den Zugriff zu jeweils einer in den Gewindebohrungen 29, 31 angeordneten Madenschraube 34; 36. Die Langlöcher 32, 33 in den Vorsprüngen 17, 22 sind in axialer Richtung ausgerichtet, so daß die Madenschrauben 34, 36 auch in extremen Verschiebestellungen des Registerstiftes 11 zugängig sind. Zum Befestigen des Registerstiftes 11 in der gewünschten Stellung werden die Madenschrauben 34; 36 im Uhrzeigersinn gedreht, so daß diese sich am Grund 18 der Einsatzleiste 3 abstützen und das Befestigungsteil 24 des Registerstifts 11 gegen eine Unterseite der Vorsprünge 17, 22 drücken. Der Registerstift 11 wird durch diese Maßnahme durch Reibschluß mit den Halterungen 12, 13 in der gewünschten Position gehalten.The elongated holes 32, 33 allow access to a grub screw 34 arranged in the threaded bores 29, 31; 36. The elongated holes 32, 33 in the projections 17, 22 are aligned in the axial direction, so that the grub screws 34, 36 are accessible even in extreme displacement positions of the register pin 11. To attach the register pin 11 in the desired Position the grub screws 34; 36 rotated clockwise so that they are supported on the base 18 of the insert bar 3 and press the fastening part 24 of the register pin 11 against an underside of the projections 17, 22. The register pin 11 is held by this measure by friction with the brackets 12, 13 in the desired position.

Das Registerteil 26 des Registerstiftes 11 weist im Schnitt nach Fig. 1 eine T-Form auf, bei dem die zwischen waagerechtem Oberteil 37 und senkrechtem Unterteil 38 gebildeten Ecken den Spannelementen der Fixier- und Spanneinrichtungen 4, 6 angepaßt gerundet ausgebildet sind.
