Definitions
- the invention relates to a device for register-oriented alignment of a plurality of printing plates arranged side by side in the axial direction on a plate cylinder of a rotary printing press according to the preamble of patent claim 1.
- each printing plate has trapezoidal stop pieces which are fixed laterally in the clamping channel and are designed as clamping bushes.
- the disadvantage of this solution is that two stop pieces must be provided laterally for each pressure plate in the clamping channel, which require a certain width of the channel.
- the channel causes the plate cylinder to run out of round as a result of channel runout, which in turn leads to register errors.
- the generic DE-PS 35 45 297 shows an adjustable side register for printing plate cylinders of a rotary printing press.
- Bent plate ends have recesses which engage in register pins or register plates in the cylinder pit.
- These register pins are connected, for example, to telescopically interlocking actuators which can be actuated from the cylinder face of the plate cylinder.
- the adjusting pieces each have an internal and external thread of different dimensions and pitch, the pitch of the threaded pieces assigned to the register plates increasing towards the outside, so that the outer pressure plate is displaced to a greater extent than the inner plate facing the cylinder center.
- the actuating elements are actuated by a common adjusting screw, which also has an internal and external thread of different dimensions and pitch.
- the disadvantage of this solution is that the printing plates arranged up to the center of the plate cylinder can only be adjusted together, ie it is assumed that the paper web is always in relation to the different dimensions and pitches of the threads of the adjusting pieces during printing changed, for example expanded.
- the expansion of the paper webs can, however, be different and depends on the paper quality and the dampening solution management of the printing plates.
- the side actuating device mentioned has a relatively large amount of play.
- the register plates located near the center of the cylinder also have a lot of play due to the lack of storage of the telescopically arranged adjusting pieces.
- Each clamping rail has register bolts that do not point into the interior of the cylinder pit.
- the clamping rails are axially connected to each other by means of double threaded bolts and can thus be moved against each other in order to bring the clamped pressure plate into the desired side register.
- the clamping rails are not cylinder insert strips because their upper surface is not adapted to the curvature of the cylinder jacket.
- the invention has for its object to provide a device for registering printing plates on plate cylinders of rotary printing presses, the printing plate beginnings are angled greater than 90 ° and are located in a narrow cylinder channel.
- the advantages of the solution according to the invention consist in particular in that the devices for guiding the printing plates can be individually displaced in the axial direction and are therefore adjustable, so that the expansion of the paper webs can be taken into account in accordance with the different dampening solution guides. Locking the insert strips with screws ensures that there is no play.
- the device according to the invention can also be used in plate cylinders which are guided through bearer rings. Due to the arrangement of a cylinder pit and the use of insert strips located therein, complex precision bores are eliminated and repair or maintenance work can be carried out without the plate cylinder having to be removed from the machine frame.
- the insert strips in the cylinder pit reduce the channel for receiving the bent ends of the pressure plates to a minimum, ie two pressure plate thicknesses, so that channel strikes are excluded.
- a partial front view of a plate cylinder 1 with a journal 10 is shown, which carries eight pressure plates, of which the pressure plates 2 to 7 are shown.
- the pressure plates 5 to 7 are only hinted at. 2 and 3, the plate cylinder 1 has on the cylinder circumference an axially extending cylinder pit 8.
- This cylinder pit 8 is easily manufactured by milling.
- Insert strips 14 to 17 are fastened in the cylinder pit 8 by means of screws 9 and 11 to 13. The screw for fastening the insert bar 14 is not shown.
- the screws 9 and 11 to 13 are received by threaded bores which run from a shoulder 19 of the cylinder groove 8 in the radial direction.
- the insert strips 15 to 17 each have a register pin 21; 22, which with a slot 25; 30 each Pressure plates 2 to 7 are connected.
- the register pin 21; 22 are preferably made of hard metal and can be glued to the insert strips 15 to 17. According to FIG. 3, the pressure plates 3; 6 added.
- the channel 23 is so narrow that just the angled pressure plates are accommodated at the ends.
- the insert strips 14 to 17 have, according to FIGS. 1 and 2, axial bores 24 which each have differential screws 26; Record 27.
- the differential screw 26 has a hexagon socket 28 for actuation from the end face of the plate cylinder 1 and has two threaded parts 29; 31 on.
- the threaded part 29 consists for example of a thread M8 x 1.25 and the threaded part 31 can consist of a thread M6 x 1.
- the differential screw 27 has threaded parts 32; 33, which are also dimensioned differently, for example M6 x 1 and M6 x 0.75.
- the threaded parts 29 and 31 to 33 correspond to corresponding threaded bores in the insert strips 14 to 17.
- a vernier 34 to 37 is provided for each side register adjustment, with part of the scale in each case on the plate cylinder 1 and the other part of the scale on the insert strips 14 to 17 is located.
- the screws 9; 11 loosened and the differential screw 28 is actuated.
- the change can be read on the vernier 34, whereby the scales can have a division of 99: 100.
- the screws 9; 11 again tightened.
- the screws for the insert bar 17, which are not shown in FIG. 1 are loosened and by actuating the external hexagon 38 connected to the differential screw 27, the insert bar 17 is actuated with the register pins and thus the pressure plate 7.
- the screws for fastening the insert strip 17 are tightened again after the required adjustment on the vernier 37 has been checked.

Description
Die Erfindung betrifft eine Vorrichtung zum registerhaltigen Ausrichten von mehreren in Achsrichtung nebeneinander angeordneten Druckplatten auf einem Plattenzylinder einer Rotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a device for register-oriented alignment of a plurality of printing plates arranged side by side in the axial direction on a plate cylinder of a rotary printing press according to the preamble of
Bei Rollenrotationsdruckmaschinen ist es bekannt, daß sich die zu bedruckende Papierbahn in Abhängigkeit von ihrer Beschaffenheit und von der Feuchtmittelaufnahme während des Druckens in ihrer Breite verändert. Diese Breitenänderung kann von Druckwerk zu Druckwerk unterschiedlich sein. Sie nimmt von Bahn- bzw. Zylindermitte nach außen hin zu. Dies hat zur Folge, daß die Druckplatten auf dem Plattenzylinder hinsichtlich des Seitenpassers individuell eingestellt werden müssen.In rotary printing presses, it is known that the width of the paper web to be printed changes depending on its nature and on the dampening solution absorption during printing. This change in width can vary from printing unit to printing unit. It increases towards the outside from the center of the path or cylinder. The result of this is that the printing plates on the plate cylinder have to be adjusted individually with regard to the side register.
Gemäß DE-PS 20 45 953 werden die Druckplatten auf dem Plattenzylinder von Rotationsdruckmaschinen in seitlicher Richtung untereinander dadurch ausgerichtet, daß jede Druckplatte jeweils seitlich im Einspannkanal fixierte trapezförmige Anschlagstücke aufweist, die als Spannbüchsen ausgebildet sind. Nachteilig bei dieser Lösung ist, daß für jede Druckplatte im Einspannkanal seitlich zwei Anschlagstücke vorgesehen sein müssen, die eine gewisse Breite des Kanals bedingen. Ein breiter Kanal jedoch führt zu einem unrunden Lauf des Plattenzylinders infolge Kanalschlag, was wiederum zu Passerfehlern führt.According to DE-PS 20 45 953, the printing plates on the plate cylinder of rotary printing presses are aligned with one another in the lateral direction in that each printing plate has trapezoidal stop pieces which are fixed laterally in the clamping channel and are designed as clamping bushes. The disadvantage of this solution is that two stop pieces must be provided laterally for each pressure plate in the clamping channel, which require a certain width of the channel. A broad one However, the channel causes the plate cylinder to run out of round as a result of channel runout, which in turn leads to register errors.
Die gattungsgemäße DE-PS 35 45 297 zeigt ein verstellbares Seitenregister für Druckplattenzylinder einer Rotationsdruckmaschine. Abgebogene Plattenenden weisen Ausnehmungen auf, die in der Zylindergrube in Registerstifte bzw. Registerplättchen eingreifen. Diese Registerstifte sind beispielsweise mit teleskopartig ineinanderliegenden Stellstücken verbunden, die von der Zylinderstirnseite des Plattenzylinders aus betätigbar sind. Die Stellstücke besitzen jeweils ein Innen- und Außengewinde verschiedener Dimension und Steigung, wobei die Steigung der den Registerplättchen zugeordneten Gewindestücke nach außen hin zunimmt, so daß die äußere Druckplatte um ein größeres Maß verschoben wird, als die zur Zylindermitte weisende innere Platte. Die Betätigung der Stellstücke erfolgt durch eine gemeinsame Stellschraube, welche ebenfalls ein Innen- und Außengewinde verschiedener Dimension und Steigung aufweist.The generic DE-PS 35 45 297 shows an adjustable side register for printing plate cylinders of a rotary printing press. Bent plate ends have recesses which engage in register pins or register plates in the cylinder pit. These register pins are connected, for example, to telescopically interlocking actuators which can be actuated from the cylinder face of the plate cylinder. The adjusting pieces each have an internal and external thread of different dimensions and pitch, the pitch of the threaded pieces assigned to the register plates increasing towards the outside, so that the outer pressure plate is displaced to a greater extent than the inner plate facing the cylinder center. The actuating elements are actuated by a common adjusting screw, which also has an internal and external thread of different dimensions and pitch.
Nachteilig bei dieser Lösung ist, daß die bis zur Mitte des Plattenzylinders angeordneten Druckplatten jeweils nur gemeinsam eingestellt werden können, d. h. es wird vorausgesetzt, daß sich die Papierbahn während des Druckes immer im Verhältnis der unterschiedlichen Dimensionen und Steigungen der Gewinde der Stellstücke verändert, beispielsweise ausdehnt. Die Ausdehnung der Papierbahnen kann jedoch unterschiedlich sein und ist abhängig von der Papierqualität sowie der Feuchtmittelführung der Druckplatten. Darüberhinaus weist die genannte Seitenstellvorrichtung durch die gemeinsame Gewindeführung von Innen- und Außengewinde ein relativ großes Spiel auf.The disadvantage of this solution is that the printing plates arranged up to the center of the plate cylinder can only be adjusted together, ie it is assumed that the paper web is always in relation to the different dimensions and pitches of the threads of the adjusting pieces during printing changed, for example expanded. The expansion of the paper webs can, however, be different and depends on the paper quality and the dampening solution management of the printing plates. In addition, due to the common thread guidance of the internal and external threads, the side actuating device mentioned has a relatively large amount of play.
Ein großes Spiel weisen auch die in der Nähe der Zylindermitte angeordneten Registerplättchen auf, infolge mangelnder Lagerung der teleskopartig angeordneten Stellstücke. Darüberhinaus ist es notwendig, in den Plattenzylinder eine aufwendige Präzisionsbohrung parallel zur Zylinderachse einzubringen, um die Stellstücke mit den Registerplättchen anzuordnen.The register plates located near the center of the cylinder also have a lot of play due to the lack of storage of the telescopically arranged adjusting pieces. In addition, it is necessary to make a complex precision bore in the plate cylinder parallel to the cylinder axis in order to arrange the adjusting pieces with the register plates.
Ein weiterer Nachteil der vorgenannten Lösung besteht darin, daß die außen an den Stirnseiten des Zylinders in der Nähe des Zylinderanfanges angeordneten Gehäuse für die Seitenverstellvorrichtungen störend wirken beim Einsatz von Laufringen für die Druckwerkszylinder, sogenannte Schmitzringe. Die Verwendung von Schmitzringen wäre bei der Anwendung dieser Lösung nicht möglich. Schließlich ist auch noch von Nachteil, daß bei Verschleiß der vorgenannten Seitenstellvorrichtungen oder bei Defekten der gesamte Druckwerkszylinder ausgebaut werden muß, um die Seitenstellvorrichtungen zu demontieren.Another disadvantage of the aforementioned solution is that the housings arranged on the outside of the end faces of the cylinder near the beginning of the cylinder have a disruptive effect on the use of side rings for the printing unit cylinders, so-called bearer rings. The use of bearer rings would not be possible using this solution. Finally, it is also disadvantageous that if the aforementioned side actuating devices are worn or in the event of defects, the entire printing unit cylinder must be removed in order to dismantle the side actuating devices.
Durch die DE-PS 22 13 614 ist eine Vorrichtung zum Befestigen und Justieren einer Mehrzahl biegsamer Druckplatten für eine Bogenrotationsdruckmaschine bekannt.From DE-PS 22 13 614 a device for attaching and adjusting a plurality of flexible printing plates for a sheet-fed rotary printing press is known.
Es sind mehrere axial verschiebbare Klemm- und Spannschienen, - je nach Anzahl der zu verwendenden Druckplatten - in einer breiten Zylindergrube vorgesehen. Jede Klemmschiene weist Registerbolzen auf, die nicht in das Zylindergrubeninnere zeigen. Die Klemmschienen sind miteinander axial mittels Doppel-Gewindebolzen verbunden und lassen sich so gegeneinander verschieben, um die jeweils geklemmte Druckplatte ins gewünschte Seitenregister zu bringen. Die Klemmschienen sind keine Zylinder-Einsatzleisten, weil ihre obere Fläche nicht an die Krümmung des Zylindermantels angepaßt ist.There are several axially displaceable clamping and tensioning rails - depending on the number of pressure plates to be used - provided in a wide cylinder pit. Each clamping rail has register bolts that do not point into the interior of the cylinder pit. The clamping rails are axially connected to each other by means of double threaded bolts and can thus be moved against each other in order to bring the clamped pressure plate into the desired side register. The clamping rails are not cylinder insert strips because their upper surface is not adapted to the curvature of the cylinder jacket.
Ebenso wie eine Befestigung von abgewinkelten Druckplatten nicht vorgesehen ist, ist es auch nicht möglich, die Klemmschienen auf einfache Weise situationsgerecht zu verstellen. Das Problem der Papierbreitenverbreiterung wird nicht angesprochen.Just as an attachment of angled pressure plates is not provided, it is also not possible to easily adjust the clamping rails according to the situation. The problem of widening the paper width is not addressed.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum registerhaltigen Aufbringen von Druckplatten auf Plattenzylinder von Rotationsdruckmaschinen zu schaffen, wobei die Druckplattenanfänge größer 90° abgewinkelt sind und sich in einem schmalen Zylinderkanal befinden.The invention has for its object to provide a device for registering printing plates on plate cylinders of rotary printing presses, the printing plate beginnings are angled greater than 90 ° and are located in a narrow cylinder channel.
Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Patentanspruches 1 gelöst.This object is achieved by the characterizing part of
Die Vorteile der erfindungsgemäßen Lösung bestehen insbesondere darin, daß die Vorrichtungen zum Führen der Druckplatten in axialer Richtung einzeln verschiebbar und somit einstellbar sind, so daß auf die Ausdehnung der Papierbahnen entsprechend den unterschiedlichen Feuchtmittelführungen Rechnung getragen werden kann. Durch das Feststellen der Einsatzleisten mittels Schrauben ist gewährleistet, daß kein Spiel entsteht. Die erfindungsgemäße Vorrichtung kann auch bei Plattenzylindern eingesetzt werden, die durch Schmitzringe geführt werden. Durch die Anordnung einer Zylindergrube und die Verwendung von darin befindlichen Einsatzleisten entfallen aufwendige Präzisionsbohrungen und es können Reparatur- oder Wartungsarbeiten ausgeführt werden, ohne daß der Plattenzylinder aus dem Maschinengestell ausgebaut werden muß. Die Einsatzleisten in der Zylindergrube verringern den Kanal zur Aufnahme der abgebogenen Enden der Druckplatten auf ein Minimum, d. h. zwei Druckplattendicken, so daß Kanalschläge ausgeschlossen sind.The advantages of the solution according to the invention consist in particular in that the devices for guiding the printing plates can be individually displaced in the axial direction and are therefore adjustable, so that the expansion of the paper webs can be taken into account in accordance with the different dampening solution guides. Locking the insert strips with screws ensures that there is no play. The device according to the invention can also be used in plate cylinders which are guided through bearer rings. Due to the arrangement of a cylinder pit and the use of insert strips located therein, complex precision bores are eliminated and repair or maintenance work can be carried out without the plate cylinder having to be removed from the machine frame. The insert strips in the cylinder pit reduce the channel for receiving the bent ends of the pressure plates to a minimum, ie two pressure plate thicknesses, so that channel strikes are excluded.

Gemäß Fig. 1 ist ausschnittsweise die Vorderansicht eines Plattenzylinders 1 mit Achszapfen 10 dargestellt, welcher acht Druckplatten trägt, von denen die Druckplatten 2 bis 7 dargestellt sind. Dabei sind die Druckplatten 5 bis 7 nur angedeutet. Gemäß Fig. 2 und 3 besitzt der Plattenzylinder 1 am Zylinderumfang eine sich in axialer Richtung erstreckende Zylindergrube 8. Diese Zylindergrube 8 ist leicht durch Fräsen herstellbar. In der Zylindergrube 8 sind mittels Schrauben 9 und 11 bis 13 Einsatzleisten 14 bis 17 befestigt. Die Schraube zur Befestigung der Einsatzleiste 14 ist nicht dargestellt. Die Schrauben 9 und 11 bis 13 werden von Gewindebohrungen aufgenommen, welche von einem Absatz 19 der Zylindergrube 8 in radialer Richtung verlaufen. Die Einsatzleisten 15 bis 17 besitzen jeweils einen Registerzapfen 21; 22, welcher mit einem Schlitz 25; 30 der jeweiligen Druckplatten 2 bis 7 in Verbindung steht. Die Registerzapfen 21; 22 bestehen vorzugsweise aus Hartmetall und können mit den Einsatzleisten 15 bis 17 verklebt sein. In dem Kanal 23 werden gemäß Fig. 3 die an den Enden abgewinkelten Druckplatten 3; 6 aufgenommen. Der Kanal 23 ist so schmal ausgeführt, daß gerade die an den Enden abgewinkelten Druckplatten Aufnahme finden. Die Einsatzleisten 14 bis 17 weisen gemäß Fig. 1 und 2 axiale Bohrungen 24 auf, welche jeweils Differentialschrauben 26; 27 aufnehmen. Die Differentialschraube 26 besitzt einen Innensechskant 28 zwecks Betätigung von der Stirnseite des Plattenzylinders 1 her und weist zwei Gewindeteile 29; 31 auf. Das Gewindeteil 29 besteht dabei beispielsweise aus einem Gewinde M8 x 1,25 und das Gewindeteil 31 kann aus einem Gewinde M6 x 1 bestehen. Die Differentialschraube 27 besitzt Gewindeteile 32; 33, welche ebenfalls unterschiedlich dimensioniert sind, beispielsweise M6 x 1 und M6 x 0,75. Die Gewindeteile 29 und 31 bis 33 korrespondieren mit entsprechenden Gewindebohrungen in den Einsatzleisten 14 bis 17. Weiterhin ist für jede Seitenregisterverstellung ein Nonius 34 bis 37 vorgesehen, wobei sich ein Teil der Skala jeweils auf dem Plattenzylinder 1 und der andere Teil der Skala auf den Einsatzleisten 14 bis 17 befindet.1, a partial front view of a
Soll beispielsweise die Druckplatte 5 verstellt werden, werden die Schrauben 9; 11 gelockert und die Differentialschraube 28 wird betätigt. Die Veränderung kann am Nonius 34 abgelesen werden, wobei die Skalen eine Teilung von 99 : 100 aufweisen können. Nach erfolgter Verstellung werden die Schrauben 9; 11 wieder festgezogen. Soll beispielsweise die Druckplatte 7 verstellt werden, so werden die in Fig. 1 nicht dargestellten Schrauben für die Einsatzleiste 17 gelockert und durch Betätigen des mit der Differentialschraube 27 verbundenen Außensechskantes 38 wird die Einsatzleiste 17 mit den Registerzapfen und somit die Druckplatte 7 betätigt.
