Description

Die vorstehende Erfindung betrifft eine Bogenfalzmaschine fuer eine Druckmaschine.The above invention relates to a sheet folding machine for a printing machine.

Wie vom Stand der Technik bekannt ist, wird z. B. in Rollenrotationsdruckmaschinen in einem Falzapparat, im Anschluss der Kuerze halber auch "Falzzylinder" genannt, ein Falzvorgang der Bogen, unter Verwendung einer Vielzahl von zangenartig ausgebildeten, steuerbaren Greifern durchgefuehrt. Die Zangen bestehen aus einem fest angeordneten Zangenteil und einem beweglichen Zangenteil und sind ueber die gesamte Axiallaenge des Falzzylinders verteilt. Zur Lagerung und zur Einstellung der Greiferzangen sind auf jeder Seite des Zylinders zwei nebeneinanderliegende scheibenartig ausgebildete Flansche vorgesehen, die untereinander und gegenueber dem Zylinder mittels Schrauben und durchgehenden Wellen montiert sind. Die scheibenartigen Flansche sind gegeneinander in entgegensetzten Drehrichtungen unter Verwendung einer Exzenterwelle verschwenkbar. Diese Exzenterwelle dient zum Einstellen des Zangenspaltes (d). Sie ist durchgehend ausgebildet und weist fuer die scheibenartigen Flansche versetzte Exzenter auf. Die Exzenterwelle steht ueber einen Sechskantkopf vom Falzzylinder ab, was ein Betaetigen der Exzenterwelle von Hand durch Ansetzen eines Schluessel ermoeglicht. Jedes bewegliche Zangenteil ist ueber ein Kugellager oder ein aehnliches Mittel mit einer Kurvenscheibe wirkverbunden, die die Oeffnungsbewegung und Schliessbewegung der beweglichen Zangenteile gegenueber den fest angeordneten Zangenteilen waehrend der Drehbewegung des Falzzylinders steuert. Der bisher beschriebene Aufbau eines Falzzylinder ist in Druckmaschinen bekannt.As is known from the prior art, z. B. in web-fed rotary printing presses in a folder, for the sake of brevity also called "folding cylinder", a folding process of the sheets is carried out using a plurality of pliers-like, controllable grippers. The pliers consist of a fixed part of the pliers and a movable part of the pliers and are distributed over the entire axial length of the folding cylinder. For storage and adjustment of the gripper pliers, two flanges in the form of disks arranged side by side are provided on each side of the cylinder, which are mounted one below the other and opposite the cylinder by means of screws and continuous shafts. The disc-like flanges are against each other opposite directions of rotation pivotable using an eccentric shaft. This eccentric shaft is used to adjust the pliers gap (d). It is continuous and has offset eccentrics for the disk-like flanges. The eccentric shaft protrudes from the folding cylinder via a hexagon head, which enables the eccentric shaft to be operated by hand by attaching a key. Each movable pliers part is operatively connected via a ball bearing or similar means to a cam which controls the opening and closing movement of the movable pliers parts relative to the fixed pliers parts during the rotational movement of the folding cylinder. The structure of a folding cylinder described so far is known in printing presses.

Bei Aenderung der zu falzenden Bogenanzahl, wobei eine geringe Bogenanzahl oder auch mehrere hundert Bogen gefalzt werden koennen, ist es erforderlich, die Zangenoeffnung, das heisst den Zangenspalt zwischen den fest angeordneten Zangenteilen und den beweglich angeordneten Zangenteilen zu regeln. Wenn man beruecksichtigt, dass die zu falzenden Bogen haeufig eine geringe Papierstaerke aufweisen und auch die Notwendigkeit besteht, die Bogen ohne Beschaedigung sicher zu greifen, so ist verstaendlich, dass die Einstellarbeiten der Zangenspaltbreite (d) aeusserst feinfuehlig durchzufuehren sind und Verstellbewegungen in der Groessenordnung von wenigen 1/10 mm erfordern.When changing the number of sheets to be folded, whereby a small number of sheets or even several hundred sheets can be folded, it is necessary to regulate the opening of the pliers, i.e. the pliers gap between the fixed pliers parts and the movably arranged pliers parts. If one takes into account that the sheets to be folded often have a low paper thickness and there is also the need to grip the sheets securely without damage, it is understandable that the adjustment work for the pliers gap width (d) must be carried out very delicately and adjustment movements in of the order of a few 1/10 mm.

Bei den bekannten Falzzylindern ist zur Aenderung des Zangenspalts zwischen den fest angeordneten Zangenteilen und den beweglich angeordneten Zangenteilen, ein Anhalten des Falzzylinders erforderlich, dies bedingt wiederum ein Anhalten der gesamten Rotationsdruckmaschine. Bei stehender Rotationsdruckmaschine ist durch einen Bedienungsmann ein Loesen saemtlicher Spannschrauben der scheibenfoermigen Flansche auf beiden Seiten des Falzzylinders erforderlich, zum Beispiel sind sieben Spannschrauben auf jeder Falzzylinderseite bei sieben vorgesehenen Falzzangen zu oeffnen, anschliessend sind durch den Bedienungsmann die erforderlichen Einstellarbeiten durchzufuehren, indem mit einem entsprechenden Schluessel auf den vorstehenden Sechskantkopf der Exzenterwelle eingewirkt wird. Nach Durchfuehrung der Einstellarbeiten sind durch den Bedienungsmann erneut saemtliche Spannschrauben anzuziehen und erst danach kann die Rotationsdruckmaschine erneut in Betrieb genommen werden.In the known folding cylinders, in order to change the pliers gap between the permanently arranged pliers parts and the movably arranged pliers parts, the folding cylinder has to be stopped, which in turn requires the entire rotary printing machine to be stopped. When the rotary printing press is at a standstill, an operator has to loosen all of the clamping screws of the disk-shaped flanges on both sides of the folding cylinder, for example, seven clamping screws must be opened on each folding cylinder side with seven intended folding pliers, after which the operator must carry out the necessary adjustment work by using an appropriate one Key on the protruding hexagon head of the eccentric shaft. After carrying out the adjustment work, the operator has to tighten all the clamping screws again and only then can the rotary printing machine be put into operation again.

Es ist also stets ein Anhalten der Rotationsdruckmaschine fuer laengere Zeit, zum Beispiel fuer wenigstens eine Stunde erforderlich. Daraus folgen erhebliche Stillstands­zeiten fuer die gesamte Maschine, was zu einer starken Verminderung des Leistungsgrades der Druckmaschine fuehrt, ferner sind bei anschliessender erneuter Inbetriebnahme der Rotationsdruckmaschine weitere Einstellvorgaengen, wie zum Beispiel Registereinstellungen durchzufuehren. Diese zusaetzlichen Einstellvorgaenge erfordern weitere Zeit, es werden unvermeidliche Fehldrucke erzeugt, ferner besteht die Gefahr, dass bei Anlauf der Maschine ein Abriss der Papierbahn erfolgt. Da der Falzzylinder im Inneren des Maschinengestells der Durckmaschine angeordnet ist, ist der Zugang zu den Spannschrauben der scheibenartigen Flansche aeusserst unbequem und schwierig, fuer den Monteur ist es haeufig erforderlich, unterhalb des Falzzylinders zu arbeiten, in einer Stellung, in der haeufig Staub- und Oelablagerungen festzustellen sind.It is therefore always necessary to stop the rotary printing press for a longer time, for example for at least one hour. This results in considerable downtimes for the entire machine, which leads to a sharp reduction in the performance of the printing press. Furthermore, when the machine is started up again, the Rotary printing press to carry out further settings, such as register settings. These additional settings require additional time, inevitable misprints are generated, and there is also the risk that the paper web will tear when the machine starts up. Since the folding cylinder is arranged inside the machine frame of the printing machine, access to the clamping screws of the disk-like flanges is extremely uncomfortable and difficult, for the installer it is often necessary to work below the folding cylinder, in a position in which dust and dust are often present Oil deposits can be found.

Obwohl der Exzenterwelle zum Einstellen des Zangenspaltes eine Massskala zugeordnet ist und entsprechende Einstellehren Verwendung finden, ist der Einstellvorgang des Zangenspaltes immer noch ein Vorgang, der in empirischer Weise durchgefuehrt wird. Wie bereits vorher erwaehnt, sind diese Einstellvorgaenge aber aeusserst genau durchzufuehren, haeufig sind Nachregulierungen im Bruchteil von nur wenigen Millimetern oder Zehntelmillimeter durchzufuehren. Sofern nach Wiederinbetriebnahme der Rotationsdruckmaschine festgestellt werden kann, dass die Einstellarbeit nicht zufriedenstellend durchgefuehrt wurde oder nach Durchfuehrung des Einstellvorganges kein sicheres Greifen und Halten der Bogen durch die Falzzangen erfolgt, wird es erneut notwendig sein, die Rotationsdruckmaschine anzuhalten, um die beschriebenen Einstellvorgaenge noch einmal in ihrer Gesamtheit durchzufuehren. Es kann festgestellt werden, dass die Einstellvorgaenge des Falzzangenspaltes immer noch einen der Arbeitsgaenge darstellt, fuer deren Durchfuehrung die gesamte Rotationsdruckmaschine anzuhalten ist.Although a dimension scale is assigned to the eccentric shaft for setting the pliers gap and appropriate setting gauges are used, the setting process of the pliers gap is still a process that is carried out empirically. As already mentioned before, these adjustment processes have to be carried out very precisely, readjustments often have to be carried out in a fraction of a few millimeters or tenths of a millimeter. If it can be determined after restarting the rotary printing press that the setting work was not carried out satisfactorily or that the sheets are not gripped and held securely by the folding pliers after the setting process has been carried out, it will be necessary again to stop the rotary printing press in order to carry out the described setting operations again in their entirety. It can be stated that the setting processes of the folding pliers gap still represent one of the working processes for which the entire rotary printing press has to be stopped.

Aufgabe der vorstehenden Erfindung ist es einen verbesserten Falzzylinder vorzuschlagen, mit dem die Nachteile der bekannten Falzzylinder behoben werden und bei dem eine direkte, automatische und kontinuierliche Einstellung des Falzzangenspaltes bei laufender Rotationsdruckmaschine moeglich ist.The object of the above invention is to propose an improved folding cylinder with which the disadvantages of the known folding cylinders are eliminated and in which a direct, automatic and continuous adjustment of the folding pliers gap is possible while the rotary printing press is running.

Es ist ferner Aufgabe der Erfindung, einen verbesserten Falzzylinder vorzuschlagen, bei dem ein Voreinstellen (presetting) des Falzzangenspaltes in automatischer Weise und auf Entfernung durchfuehrbar ist.It is also an object of the invention to propose an improved folding cylinder, in which a presetting of the folding pliers gap can be carried out automatically and at a distance.

Die erfindungsgemaesse Aufgabe wird mit dem erfindungsgemaessen Falzzylinder fuer eine Druckmaschine dadurch geloest, dass dem Antriebsende der fuer den Einstellvorgang des Zangenspaltes vorgesehenen Exzenterwelle ein steuerbarer Drehantrieb zugeordnet ist, der eine Feineinstellung in beiden Drehrichtungen der Exzenterwelle erlaubt, und dass der Drehantrieb direkt am Falzzylinder, zum Beispiel an einem aussenliegenden scheibenfoermigen Flansch des Falzzylinders angeordnet ist. Weitere Merkmale des erfindungsgemaessen Falzzylinders koennen den Unteranspruechen und der Beschreibung entnommen werden.The object according to the invention is achieved with the folding cylinder according to the invention for a printing press in that a controllable rotary drive is assigned to the drive end of the eccentric shaft provided for the setting process of the pliers gap, which allows fine adjustment in both directions of rotation of the eccentric shaft, and that the rotary drive directly on the folding cylinder for Example on an outside disc-shaped flange of the folding cylinder is arranged. Further features of the folding cylinder according to the invention can be found in the subclaims and the description.

Mit dem erfindungsgemaessen Falzzylinder koennen wesentliche Vorteile erzielt werden:
Einmal kann der Einstellvorgang des Falzzangenspaltes bei sich drehendem Falzzylinder erfolgen, es ist nicht erforderlich, die Rotationsdruckmaschine anzuhalten. Ferner erfolgt der Einstellvorgang in Realzeit. Die fuer den Einstellvorgang notwendige Zeit betraegt nur wenige Sekunden. Durch den Bedienungsmann kann direkt und visuell das Ausmass der vorgenommenen Einstellung ueberprueft werden, das heisst der Greifvorgang der Falzzange kann direkt am gefahrten Bogen ueberprueft werden. Im Falle weiterer Feineinstellvorgaenge koennen diese durch den Bedienungsmann schnell durchgefuehrt werden, indem zum Beispiel auf eine Richtungsumkehreinrichtung eingewirkt wird, um dadurch eine Feineinstellung in entgegengesetzter Richtung vorzunehmen und ein sicheres und einwandfreies Greifen der Bogen, ohne Beschaedigung der einzelnen Bogen zu ermoeglichen. Es kann auf die zahlreichen Spannschrauben am scheibenartigen Flansch verzichtet werden, die vorgesehenen scheibenfoermigen Flansche halten in einwandfreier Weise die vorbestimmte Einstellage bei, besonders durch Vorsehung einer Antriebsvorrichtung fuer die verdrehbare Exzenterwelle in beiden Drehrichtungen. Dabei ist die Antriebsvorrichtung nicht reversibel hinsichtlich der Kraftuebertragung ausgebildet. Diese nicht reversible Antriebsvorrichtung kann zum Beispiel aus einer Schraubenspindel in Verbindung mit einem Schneckenrad bestehen, welche ueber einen Pneumatikmotor angetrieben wird. Die Verwendung eines Pneumatikmotors hat den Vorteil, dass dieser geringen Platzbedarf hat und direkt auf dem Getriebemotor am Falzzylinder montiert werden kann. Die Verwendung eines Pneumatikmotors ermoeglicht ferner einen feinfuehligen Einstellvorgang durchzufuehren.Significant advantages can be achieved with the folding cylinder according to the invention:
On the one hand, the setting process of the folding pliers gap can take place with the folding cylinder rotating, it is not necessary to stop the rotary printing press. Furthermore, the setting process takes place in real time. The time required for the setting process is only a few seconds. The operator can directly and visually check the extent of the setting made, that is, the gripping process of the folding pliers can be checked directly on the sheet being driven. In the case of further fine adjustment processes, these can be carried out quickly by the operator, for example by acting on a direction reversing device, in order thereby to carry out a fine adjustment in the opposite direction and to enable safe and perfect gripping of the sheets without damaging the individual sheets. There is no need for the numerous clamping screws on the disc-like flange; the disc-shaped flanges provided hold in a flawless manner the predetermined setting position, especially by providing a drive device for the rotatable eccentric shaft in both directions of rotation. The drive device is not designed to be reversible with regard to the transmission of force. This non-reversible drive device can consist, for example, of a screw spindle in connection with a worm wheel, which is driven by a pneumatic motor. The use of a pneumatic motor has the advantage that it takes up little space and can be mounted directly on the geared motor on the folding cylinder. The use of a pneumatic motor also enables a sensitive adjustment process to be carried out.

Ein weiterer Vorteil des erfindungsgemaessen Falzzylinders ist darin zu sehen, dass eine automatische Einstellung des Falzzangenspaltes dadurch moeglich wird, dass der Exzenterwelle ein Encoder oder gleichartiges Lagebestimmungsmittel zugeordnet ist, wobei der Encoder seinerseits einer Presettingeinrichtung zugeordnet sein kann, die auf den steuerbaren Motor einwirkt. Somit wird es moeglich, eine Vielzahl von verschiedenen Spaltbreiten fuer die Falzzangen im voraus durch Abruf rasch und genau einzustellen.Another advantage of the folding cylinder according to the invention can be seen in the fact that an automatic adjustment of the folding pliers gap is made possible by the fact that an encoder or similar position determining means is assigned to the eccentric shaft, whereby the encoder in turn can be assigned to a presetting device which acts on the controllable motor. This makes it possible to quickly and accurately set a large number of different gap widths for the folding pliers in advance by calling them up.

Somit kann der Motor 21 wahlweise in der einen oder in der anderen Drehrichtung angetrieben werden.According to the invention, with the protruding end 14 of the eccentric shaft 13, which is responsible for the adjustment process, a worm wheel 17 is arranged, with which a threaded spindle 18 is operatively connected, which is arranged on the output shaft 19 of a reducing drive 20. A drive of the Harmony Drive (USA) type is advantageously used as the reducing drive, this drive advantageously being operatively connected to a pneumatic motor 21. The line for the supply of compressed air is indicated schematically at 22. 23 with a reversing device is marked, which for the supply of compressed air in the line 24 or in the Line 25 is used to drive the motor 21. Thus, the motor 21 can be driven either in one or the other direction of rotation.

Auf der Welle 13 ist ein drehbarer Verteiler 26 vorgesehen, der fuer die staendige Zufuhr von Druckluft an die Leitungen 24 und 25 ueber die Welle 13 sorgt, um die Antriebseinrichtungen 21, 20 und 18, die fest ueber das Teil 27 am Falzzylinder 1 bzw. am aeusseren Flansch 5 des Wellenendes 14 angeordnet sind, mit Druckluft zu versorgen. Erfindungsgemaess weist die Exzenterwelle 13 an ihrem Ende 30 einen Encoder 31 zur Feststellung der jeweils eingenommenen Winkelposition der Exzenterwelle 13 auf. Der Encoder 31 oder ein aehnliches Geraet zur Feststellung der genauen Winkellage der Exzenterwelle steht ueber den Verbindungsleitungen 32 und 33 und ueber eine Buerstenanordnung 34 mit einer NC Steuervorrichtung 35 in Wirkverbindung.A rotatable distributor 26 is provided on the shaft 13, which ensures the constant supply of compressed air to the lines 24 and 25 via the shaft 13, around the drive devices 21, 20 and 18, which are fixed via the part 27 on the folding cylinder 1 or are arranged on the outer flange 5 of the shaft end 14 to be supplied with compressed air. According to the invention, the eccentric shaft 13 has at its end 30 an encoder 31 for determining the respectively assumed angular position of the eccentric shaft 13.

Die Arbeitsweise des verbesserten Falzzylinders gemaess der vorangegangenen Beschreibung ist folgende:
Soll der Zangenspalt (d) vergroessert oder verkleinert werden, ist es ausreichend, den Motor 21 ueber einen Steuerschalter 23 in der einen oder anderen Drehrichtung anzutreiben. Es erfolgt eine entsprechende Drehbewegung der Exzenterwelle 13, die fuer den Einstellvorgang verantwortlich ist. Es kann also eine Drehbewegung der Exzenterwelle 13 in der einen oder in der anderen Richtung vorgenommen werden. Diese Drehbewegung kann bei rotierendem Falzzylinder und bei laufender Rotationsdruckmaschine erfolgen.The operation of the improved folding cylinder according to the previous description is as follows:
If the pliers gap (d) is to be enlarged or reduced, it is sufficient to drive the motor 21 in one or the other direction of rotation via a control switch 23. There is a corresponding rotary movement of the eccentric shaft 13, which is responsible for the adjustment process. So there can be a rotary movement of the Eccentric shaft 13 can be made in one or the other direction. This rotary movement can take place with the folding cylinder rotating and with the rotary printing press running.

Fuer den Einstellvorgang wird die Bedienungsperson also den Zangenspalt durch Einwirken auf den Steuerschalter 23 aendern und durch Inaugenscheinnahme des Falzvorganges durch Ueberpruefen der gefalzten Bogen pruefen.For the setting process, the operator will therefore change the pliers gap by acting on the control switch 23 and by inspecting the folding process by checking the folded sheets.

Bei einem Presettingvorgang, der durch Betaetigen einer Tastatur oder durch Abrufen eingespeicherter Werte durchfuehrbar ist, wirkt die NC-Steuereinheit 35 direkt auf den Motor 21 oder auf den Steuerschalter 23 unter Zuhilfenahme des Encoders 31 einwirken.In the case of a presetting process which can be carried out by pressing a keyboard or by calling up stored values, the NC control unit 35 acts directly on the motor 21 or on the control switch 23 with the aid of the encoder 31.
