Definitions
- the invention relates to a device for receiving a roller journal of a roller in the printing unit of a rotary printing press, the roller being arranged in the installed state almost axially parallel with respect to two further rollers of the printing unit and being in contact with the guide surfaces of both rollers.
- An inking unit for rotary printing presses is known from the prior art, DE 33 42 853 C2, which can be converted from newspaper printing to commercial printing by installing additional components.
- end shields are provided, in which the transfer rollers are received.
- the adjustment of the roller gap between one of the transfer rollers and an application roller takes place via a pressure screw and is at the individual discretion of the printer.
- Adjustable roller bearings of the inking rollers and transfer rollers are disclosed here. Sliding blocks are fastened in the side walls so that the bearing body can be moved by turning an adjusting screw in order to vary the contact force in the contact zone. The size of the contact force is indicated by the compression path of a spring or a spring assembly. After determining the setting position to generate a defined contact force, the bearing body is attached to the side wall in the determined position. This device does not automatically adapt the contact zone to parameters that change during machine operation.
- the object of the invention is to optimize a roller bearing in such a way that an automatic adjustment of rotating bodies is achieved while the arrangement can be used universally.
- the screw-in element can be moved up to a predetermined fixed position in a bearing body. On the one hand this prevents incorrect settings by the printer, on the other hand there is no need for countering. Set-up times for adjustment can be drastically reduced.
- the bearing body can be attached in any orientation in several positions in the inking unit or printing unit. This allows universal use of the device for receiving roller journals and avoiding them elaborate adaptation constructions. Furthermore, the bearing body has guide cams. As a result, the weight of the roller can be absorbed by the lower guide cams in an adjustment in which the dead weight of the roller is to be eliminated. For example, it can be placed exactly between two rubbers by the contact force exerted by the pressing element.
- the guide cams have inner surfaces whose spacing from one another is greater than the diameter of a roller journal to be accommodated. In this way, it can be achieved in an advantageous manner that the picked-up roller can shift laterally during a shut-off movement - for example the application rollers. With the appropriate installation position, the roller can align itself exactly between the rubbers.
- a cavity is formed between the pressure element and the screw-in element, which receives a compression spring.
- This component generating the contact force can also be designed as a spring assembly; the use of disc springs is also conceivable.
- the adjusting forces are adjusted by using compression springs with different spring characteristics or by changing the installation space for the compression spring either by using a modified pressure element or by installing a modified screw-in element.
- the contact forces between rollers at certain installation points in the inking unit can be adjusted by installing appropriately designed and preassembled devices for receiving rollers. A time-consuming adjustment when installing the rollers by the printer is not necessary. Due to the uniform structure of the device for receiving roller journals at various installation points in the inking unit or printing unit, the printer quickly gets used to it the handling of this device, for the operation of which only a tool is necessary.
- Fig. 1 shows a device according to the invention for receiving rotary bodies in a vertical installation position.
- a bearing body 1 is provided with a thread in its upper area, while it has two guide cams 1a in its lower area.
- a roller pin 4a of a roller 4 is located between mutually facing inner surfaces 1b of the guide cams 1a.
- the lateral surfaces of two rubbers 9, 10 serve as guide surfaces for the roller 4.
- a screw-in element 5, which has a cavity 5a, is inserted into the thread made in the upper region of the bearing body 1.
- a pressure element 6 is movably arranged in the cavity 5a.
- the pressing element 6 has a slim neck region 6a in addition to a head region 6b with an enlarged diameter. The pressing element 6 is secured against falling out by the locking pin 7.
- a compression spring 8 is supported on the one hand at the upper end of the cavity 5a, while its opposite end abuts the head region 6b of the pressing element 6.
- the geometry of the cavity 5a can be achieved by installing a pressure element 6 same overall length, which has a shortened or extended head region 6b, can be varied, whereby a change in the positioning forces can be achieved.
- the screw-in element 5 which is designed in the upper area with a common wrench size, is screwed into the bearing body 1 during assembly in the bearing body 1 until the collar rests, as a result of which countering is not required.
- the roller pin 4a of the roller 4 lying between the inner surfaces 1b of the guide cams 1a is positioned between the rubbers 9, 10 by the head region 6b of the pressing elements 6 with a defined preload and a defined roller contact width.
- the roller contact width is in turn determined by the compression spring 8 acting on the head region 6b of the pressing element 6. To remove the roller 4, only the screw-in elements 5 in the bearing body 1 have to be turned back until the roller pin 4a can be passed between the guide cam 1a and the pressing element 6b.

- This view can be both a vertical and a horizontal orientation in the machine.
- the bearing body 1 can also be installed inclined at a certain angle in the machine.
- transfer rollers as well as dampening or ironing rollers can be easily and safely accommodated in one printing unit.
- these could also be adapted, for example via a threaded spindle, to larger diameters of roller journals 4a.
- the simple structure of the device and the quick assembly allow a versatile universal use of the device according to the invention for holding rollers, both on the drive side and on the operating side of a processing machine.
- the universal use of the device according to the invention for receiving rollers is favored by the symmetrical structure of the bearing body. This ensures good accessibility, ease of use and use on the drive and operator side.
- bearing body 1 allows only one storage configuration to be used instead of many complex adaptation designs. Since the storage configuration according to the invention consists of only a few Components exist, the manufacturing costs are lower; it is also possible to use only the bearing according to the invention for each printing unit or inking unit for the storage of transfer rollers. This serves to standardize and save set-up time when adjusting the rollers. The component expansions caused by heating during longer machine running times can be automatically compensated, so that the service life of the components - for example by reducing the flexing work in the roller contact zones - and by reducing the component stresses can be increased considerably.

Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Aufnahme eines Walzenzapfens einer Walze im Druckwerk einer Rotationsdruckmaschine, wobei die Walze im eingebauten Zustand nahezu achsparallel bezüglich zweier weiterer Walzen des Druckwerkes angeordnet ist und mit den Führungsflächen beider Walzen in Kontakt steht.The invention relates to a device for receiving a roller journal of a roller in the printing unit of a rotary printing press, the roller being arranged in the installed state almost axially parallel with respect to two further rollers of the printing unit and being in contact with the guide surfaces of both rollers.
Aus dem Stand der Technik, DE 33 42 853 C2 ist ein Farbwerk für Rotationsdruckmaschinen bekannt, welches durch den Einbau zusätzlicher Komponenten von zeitungsdruck auf Akzidenzdruck umrüstbar ist. Dazu sind Lagerschilde vorgesehen, in welchen die Übertragungswalzen aufgenommen werden. Die Einstellung des Walzenspaltes zwischen einer der Übertragungswalzen und einer Auftragswalze erfolgt über eine Druckschraube und ist in das individuelle Ermessen des Druckers gestellt.An inking unit for rotary printing presses is known from the prior art, DE 33 42 853 C2, which can be converted from newspaper printing to commercial printing by installing additional components. For this purpose, end shields are provided, in which the transfer rollers are received. The adjustment of the roller gap between one of the transfer rollers and an application roller takes place via a pressure screw and is at the individual discretion of the printer.
Weiterhin ist eine Ausführung aus der US-PS 31 67 010 bekannt. Hier sind verstellbare Walzenlagerungen der Farbauftragswalzen und Übertragungswalzen offenbart. In Seitenwänden sind Gleitsteine befestigt, so daß Lagerkörper über Verdrehung einer Einstellschraube verschoben werden können, um die Anstellkraft in der Kontaktzone zu variieren. Die Größe der Anstellkraft wird durch den Kompressionsweg einer Feder oder eines Federnpaketes angezeigt. Nach Ermittlung der Einstellposition zur Erzeugung einer definierten Anstellkraft, wird der Lagerkörper in der ermittelten Position an der Seitenwand befestigt. Eine selbsttätige Anpassung der Kontaktzone an sich während des Maschinenbetriebes ändernde Parameter ist in dieser Einrichtung nicht gegeben.Furthermore, an embodiment is known from US-PS 31 67 010. Adjustable roller bearings of the inking rollers and transfer rollers are disclosed here. Sliding blocks are fastened in the side walls so that the bearing body can be moved by turning an adjusting screw in order to vary the contact force in the contact zone. The size of the contact force is indicated by the compression path of a spring or a spring assembly. After determining the setting position to generate a defined contact force, the bearing body is attached to the side wall in the determined position. This device does not automatically adapt the contact zone to parameters that change during machine operation.
In Weiterbildung des Standes der Technik, liegt der Erfindung die Aufgabe zugrunde, ein Walzenlager derart zu optimieren, daß eine selbsttätige Justage von Rotationskörpern bei universeller Verwendbarkeit der Anordnung erreicht wird.In a further development of the prior art, the object of the invention is to optimize a roller bearing in such a way that an automatic adjustment of rotating bodies is achieved while the arrangement can be used universally.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruches 1 gelöst.According to the invention the object is solved by the features of
Die Vorteile dieser Lösung liegen darin, daß eine Justage des aufzunehmenden Rotationskörpers, sei es eine Walze oder ein Zylinder, nicht mehr in das Ermessen des Bedienungspersonals gestellt ist, sondern automatisch nach Einbau des Rotationskörpers durch Andrückelement und Einschraubelement gegeben ist. Subjektive Fehleinstellungen, die bei Erwärmung der Maschine nach längerem Betrieb zur Zerstörung von Walzenbelägen durch Walkarbeit führen können, werden ausgeschlossen. Mit nur einem Werkzeug kann die Walze gesichert werden; eine Konterung kann entfallen. Temperaturänderungen im Farbwerk und daraus resultierende Spannungsdifferenzen können sich nunmehr durch eine Relativbewegung zwischen Andrückelement und Einschraubelement ausgleichen, wobei die Walzenkontaktbreite weitgehend gewahrt bleibt.The advantages of this solution are that an adjustment of the rotating body to be accommodated, be it a roller or a cylinder, is no longer at the discretion of the operating personnel, but is automatically given by the pressing element and screwing element after the rotating body has been installed. Subjective incorrect settings, which can lead to the destruction of roller coverings due to flexing work if the machine is warmed up after a long period of operation, are excluded. The roller can be secured with just one tool; a counterattack can be omitted. Temperature changes in the inking unit and the resulting voltage differences can now be compensated for by a relative movement between the pressure element and the screw-in element, the roller contact width being largely preserved.
In weiterer Ausgestaltung des der Erfindung zugrundeliegenden Gedankens ist das Einschraubelement bis zu einer vorbestimmten Fixposition in einem Lagerkörper bewegbar. Dadurch werden einerseits Fehleinstellungen durch den Drucker vermieden, andererseits kann eine Konterung entfallen. Die Rüstzeiten bei der Justage können drastisch verringert werden.In a further embodiment of the idea on which the invention is based, the screw-in element can be moved up to a predetermined fixed position in a bearing body. On the one hand this prevents incorrect settings by the printer, on the other hand there is no need for countering. Set-up times for adjustment can be drastically reduced.
Weiterhin ist der Lagerkörper in beliebig orientierter Einbaulage an mehreren Stellen im Farbwerk oder Druckwerk anbringbar. Dies erlaubt eine universelle Verwendbarkeit der Vorrichtung zur Aufnahme von Walzenzapfen und der Vermeidung aufwendiger Anpassungskonstruktionen. Ferner weist der Lagerkörper Führungsnocken auf. Dadurch kann bei einer Justage, bei der das Eigengewicht der Walze zu eliminieren ist, durch die jeweils unteren Führungsnocken das Gewicht der Walze aufgenommen werden. So kann sie durch die vom Andrückelement ausgeübte Anstellkraft beispielsweise genau zwischen zwei Reibern plaziert werden.Furthermore, the bearing body can be attached in any orientation in several positions in the inking unit or printing unit. This allows universal use of the device for receiving roller journals and avoiding them elaborate adaptation constructions. Furthermore, the bearing body has guide cams. As a result, the weight of the roller can be absorbed by the lower guide cams in an adjustment in which the dead weight of the roller is to be eliminated. For example, it can be placed exactly between two rubbers by the contact force exerted by the pressing element.
In weiterer Ausgestaltung der Vorrichtung zur Aufnahme von Walzenzapfen verfügen die Führungsnocken über Innenflächen, deren Abstand voneinander größer ist als der Durchmesser eines aufzunehmenden Walzenzapfens. So kann in vorteilhafter Weise erreicht werden, daß sich bei einer Abstellbewegung - etwa der Auftragswalzen - die aufgenommene Walze seitlich verlagern kann. Bei entsprechender Einbaulage kann sich die aufgenommene Walze exakt zwischen den Reibern ausrichten.In a further embodiment of the device for receiving roller journals, the guide cams have inner surfaces whose spacing from one another is greater than the diameter of a roller journal to be accommodated. In this way, it can be achieved in an advantageous manner that the picked-up roller can shift laterally during a shut-off movement - for example the application rollers. With the appropriate installation position, the roller can align itself exactly between the rubbers.
Schließlich ist vorgesehen, daß zwischen dem Andrückelement und dem Einschraubelement ein Hohlraum ausgebildet ist, der eine Druckfeder aufnimmt. Dieses, die Anstellkraft erzeugende Bauteil kann auch als Federnpaket ausgeführt sein; auch die Verwendung von Tellerfedern ist denkbar. Die Anpassung der Anstellkräfte erfolgt durch Verwendung von Druckfedern mit unterschiedlicher Federcharakteristik oder durch eine Veränderung des Einbauraumes für die Druckfeder entweder durch Verwendung eines modifizierten Andrückelementes oder durch den Einbau eines modifizierten Einschraubelementes. Je nach Einbaufall kann eine Anpassung der Anstellkräfte zwischen Walzen an bestimmten Einbaustellen im Farbwerk durch den Einbau enstprechend ausgelegter und vormontierter Vorrichtungen zur Aufnahme von Walzen erfolgen. Eine zeitraubende Justage beim Einbau der Walzen durch den Drucker entfällt. Durch den einheitlichen Aufbau der Vorrichtung zur Aufnahme von Walzenzapfen an verschiedenen Einbaustellen im Farbwerk bzw. Druckwerk, gewöhnt sich der Drucker schnell an den Umgang mit dieser Vorrichtung, zu deren Bedienung nur noch ein Werkzeug notwendig ist.Finally, it is provided that a cavity is formed between the pressure element and the screw-in element, which receives a compression spring. This component generating the contact force can also be designed as a spring assembly; the use of disc springs is also conceivable. The adjusting forces are adjusted by using compression springs with different spring characteristics or by changing the installation space for the compression spring either by using a modified pressure element or by installing a modified screw-in element. Depending on the installation, the contact forces between rollers at certain installation points in the inking unit can be adjusted by installing appropriately designed and preassembled devices for receiving rollers. A time-consuming adjustment when installing the rollers by the printer is not necessary. Due to the uniform structure of the device for receiving roller journals at various installation points in the inking unit or printing unit, the printer quickly gets used to it the handling of this device, for the operation of which only a tool is necessary.

Fig. 1 zeigt eine erfindungsgemäße Vorrichtung zur Aufnahme von Rotationskörpern in vertikaler Einbaulage. Ein Lagerkörper 1 ist in seinem oberen Bereich mit einem Gewinde versehen, während er in seinem unteren Bereich zwei Führungsnocken 1a aufweist. Zwischen einander zugewandten Innenflächen 1b der Führungsnocken 1a befindet sich ein Walzenzapfen 4a einer Walze 4. Im gezeigten Beispiel dienen die Mantelflächen zweier Reiber 9,10 als Führungsflächen für die Walze 4.
In das im oberen Bereich des Lagerkörpers 1 ausgeführte Gewinde ist ein Einschraubelement 5 gefügt, welches einen Hohlraum 5a aufweist. Im Hohlraum 5a ist ein Andrückelement 6 beweglich angeordnet. Das Andrückelement 6 weist einen schlanken Halsbereich 6a neben einem im Durchmesser vergrößerten Kopfbereich 6b auf. Das Andrückelement 6 ist durch den Sicherungsstift 7 gegen Herausfallen gesichert.Fig. 1 shows a device according to the invention for receiving rotary bodies in a vertical installation position. A
A screw-in
Eine Druckfeder 8 stützt sich einerseits am oberen Ende des Hohlraumes 5a ab, während deren gegenüberliegendes Ende am Kopfbereich 6b des Andrückelementes 6 anliegt. Die Geometrie des Hohlraumes 5a kann durch Einbau eines Andrückelementes 6 gleicher Gesamtlänge, welches einen verkürzten oder verlängerten Kopfbereich 6b aufweist, variiert werden, wodurch eine Veränderung der Anstellkräfte erzielbar ist. Gleiches gilt selbstverständlich auch bei Ausführungen des Einschraubelementes 5 mit einem verkürzten oder verlängerten Hohlraum 5a.A
Das Im oberen Bereich mit einer gängigen Schlüsselweite ausgeführte Einschraubelement 5 wird bei der Montage im Lagerkörper 1 bis zur Anlage des Bundes in den Lagerkörper 1 festgeschraubt, wodurch eine Konterung entfällt. Der zwischen den Innenflächen 1b der Führungsnocken 1a liegende Walzenzapfen 4a der Walze 4 wird durch den Kopfbereich 6b der Andrückelemente 6 mit definierter Vorspannung und definierter Walzenkontaktbreite zwischen den Reibern 9,10 positioniert. Durch den, den Durchmesser des Walzenzapfens 4a übersteigenden Abstand zwischen den Innenflächen 1b der Führungsnocken 1a, vermag die Walze 4 einer evtl. auszuführenden Abstellbewegung zu folgen.The screw-in
In Fig. 2 ist eine horizontale Einbaulage eines Lagerkörpers 1 dargestellt. Das Eigengewicht der Walze 4 wird nunmehr vom unteren der beiden Führungsnocken 1a aufgenommen.2 shows a horizontal installation position of a bearing
Die Walzenkontaktbreite wird wiederum durch die auf den Kopfbereich 6b des Andrückelementes 6 wirkende Druckfeder 8 bestimmt. Zum Ausbau der Walze 4 müssen lediglich die Einschraubelemente 5 im Lagerkörper 1 soweit zurückgedreht werden, bis sich der Walzenzapfen 4a zwischen dem Führungsnocken 1a und dem Andrückelement 6b hindurch führen läßt.The roller contact width is in turn determined by the
Zur Kapselung gegen evtl. eintretende Farbrückstände oder agressive Lösungs- und Reinigungsmittel, können die Hohlräume 5a der Einschraubelemente 5 mit einer Fettfüllung versehen werden. Danach ist die Vorrichtung zur Aufnahme von Walzen 4 als wartungsfrei anzusehen.To encapsulate any color residues or aggressive solvents and cleaning agents, the
Fig. 3 schließlich zeigt eine Vorderansicht einer erfindungsgemäßen Vorrichtung zur Aufnahme von Walzen. Mittels Schrauben 2 ist der Lagerkörper 1 mit der Seitenwand 3 verbunden, wobei die Schraubenköpfe in Ansenkungen des Lagerkörpers 1 liegen. Bei dieser Ansicht kann es sich sowohl um eine vertikal als auch um eine horizontal in die Maschine orientierte Einbaulage handeln. Der Lagerkörper 1 kann auch unter einem bestimmten Winkel geneigt in die Maschine eingebaut werden. Mit Hilfe dieser Lagerungskonfiguration können sowohl Übertragungswalzen als auch Feucht- oder Bügelwalzen einfach und sicher in einer Druckeinheit aufgenommen werden. Zur Anpassung des Abstandes der Innenflächen 1b der Führungsnocken 1a, könnten diese auch, beispielsweise via Gewindespindel, an größere Durchmesser von Walzenzapfen 4a angepaßt werden.3 finally shows a front view of a device according to the invention for receiving rollers. The bearing
Der einfache Aufbau der Vorrichtung sowie die schnelle Montage erlauben einen vielfältigen universellen Einsatz der erfindungsgemäßen Vorrichtung zur Aufnahme von Walzen, sowohl auf der Antriebs- als auch auf der Bedienungsseite einer Verarbeitungsmaschine.The simple structure of the device and the quick assembly allow a versatile universal use of the device according to the invention for holding rollers, both on the drive side and on the operating side of a processing machine.
Die universelle Verwendbarkeit der erfindungsgemäßen Vorrichtung zur Aufnahme von Walzen wird durch den symmetrischen Aufbau des Lagerkörpers begünstigt. Gute Zugänglichkeit, leichte Bedienbarkeit und Verwendung auf Antriebs- und Bedienseite sind dadurch gegeben.The universal use of the device according to the invention for receiving rollers is favored by the symmetrical structure of the bearing body. This ensures good accessibility, ease of use and use on the drive and operator side.
Die Verwendung eines gleichen Lagerkörpers 1 als Grundkörper gestattet es, nur eine Lagerungskonfiguration statt vieler aufwendiger Anpassungskonstruktionen zu verwenden. Da die erfindungsgemäße Lagerungskonfiguration aus nur wenigen Komponenten besteht, sind die Herstellkosten geringer; ferner ist es möglich pro Druckwerk bzw. Farbwerk für die Lagerung von Übertragungswalzen nur die erfindungsgemäße Lagerung zu verwenden. Dies dient der Vereinheitlichung sowie der Rüstzeiteinsparung bei der Justage der Walzen. Die bei längerer Maschinenlaufzeit auftretenden Bauteildehnungen durch Erwärmung können automatisch kompensiert werden, so daß die Lebensdauer der Bauteile - beispielsweise durch Herabsetzung der Walkarbeit in den Walzenkontaktzonen - und durch Verminderung der Bauteilverspannungen beträchtlich erhöht werden kann.The use of the
