Offsetdruckmaschinen weisen üblicherweise eine Längswelle auf, die von einem oder mehreron Elektromotoren angetrieben wird ( DE 42 19 969 A1 ). Von dieser Längswelle zweigen über Getriebe und Kupplungen Antriebswellen ab, mit denen auf die Druckeinheiten, Abrollungen, Falzeinheiten und Funktionsgruppen, wie beispielsweise Zug- und Überführwalzen, Trichterwalzen, Schneidwalzen, Kühlwerke, getrieben wird. Die Getriebe enthalten meist weitere Kupplungen und Zahnräder. Der Antrieb ist also technisch sehr aufwendig und kostspielig.Offset printing machines usually have a longitudinal shaft which is driven by one or more electric motors ( DE 42 19 969 A1 ). Drive shafts branch off from this longitudinal shaft via gears and clutches, with which drive units are driven onto the printing units, unwinds, folding units and functional groups, such as, for example, drawing and transfer rollers, hopper rollers, cutting rollers and cooling units. The transmissions usually contain other clutches and gears. The drive is so technically very expensive and expensive.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Offsetdruckmaschine Zylinder und Funktionsgruppen mit geringem technischem Aufwand anzutreiben, einzustellen und zu steuern und hierfür Einstell- und Steuervorrichtungen zu schaffen sowie eine Zylinderkonfiguration mit Einzelmotorenantrieben aufzuzeigen.The invention has for its object to drive in an offset printing cylinder and functional groups with little technical effort to adjust and control and to create adjustment and control devices and to show a cylinder configuration with single motor drives.

Die Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Durch den Einzelmotorantrieb können Wellen, Getriebe, Kupplungen und Stellvorrichtungen entfallen. Zusätzlich entfallen für die vorgenannten Bauteile die elektrischen Überwachungseinrichtungen.The object is solved by the features of the independent claims. The single motor drive eliminates shafts, gears, clutches and actuators. In addition, eliminates the electrical monitoring devices for the aforementioned components.

Aus der JP-A-632665 ist bereits ein gattungsgemäßer Einzelmotorenantrieb für Offset-Druckmaschinen bekannt, bei dem diskrete externe Registersignale von einem Registerimpulssignal-Generator an jeden Antriebsmotor gegeben werden, jedoch wird nichts offenbart bezüglich des Plattenwechsels oder Wegausgleich. Auch die EP 0 567 741 A1 und die GB 226 16 29-A sagen zu diesem Problem nichts aus, sondern beschäftigen sich mit Synchronisationsproblemen, insbesondere zwischen Druckwerken bzw. Druckwerksgruppen. Der Stand der Technik gibt auch keinen Hinweis bezüglich unterschiedlicher Bahnwegskompensation, die demnach dort konventional, d. h. mit Ausgleichswalzen erfolgt. Das gleiche gilt für die Schnittregistervoreinstellung, gegebenenfalls mit einer Regelmöglichkeit.From the JP-A-632665 A generic single motor drive for offset printing machines is already known in which discrete external register signals are given from a register pulse signal generator to each drive motor, however, nothing is disclosed with respect to disk replacement or path compensation. Also the EP 0 567 741 A1 and the GB 226 16 29-A do not comment on this problem, but deal with synchronization problems, in particular between printing units or groups of printing groups. The prior art also gives no indication regarding different Bahnwegskompensation, which therefore takes place there conventional, ie with compensating rollers. The same applies to the cut register presetting, optionally with a control option.

Das erfindungsgemäße Konzept ermöglicht also bei Bedarf ohne zusätzliche mechanische Mittel allein mit den Antriebsmotoren die Umfangs- bzw. Farbregisterregelung, Bahnwegausgleich und Schnittregistereinstellung und gewünschtenfalls zusätzlich mit Schnittregisterregelung und Farb- bzw. Umfangsregisterregelung. Hierfür gibt der Stand der Technik kein Vorbild.The inventive concept thus allows, if necessary without additional mechanical means alone with the drive motors, the circumferential or color register control, Bahnwegausgleich and cut register setting and, if desired, in addition with cut register control and color or circumferential register control. For this, the state of the art is no model.

In den Figuren 1 bis 4 sind Druckeinheiten dargestellt, die von jeweils einem separaten, winkelgeregelten Elektromotor angetrieben werden. In Fig. 1 enthält die Druckeinheit zwei von jeweils einem Formzylinder 1.1, 1.2 und einem Übertragungszylinder 2.1, 2.2 gebildete Druckwerke 3, 4. Jeder Form- und Übertragungszylinder 1.1, 1.2, 2.1, 2.2 ist mit seinen Zapfen in Seitenwänden 5, 6 gelagert (Fig. 5). Auf der bedienseitigen Seitenwand 5 ist ein winkelgeregelter Elektromotor 7 angeordnet, der den Formzylinder 1.1 antreibt. über die Ausbildung dieser Antriebsverbindung werden später Aussagen gemacht. Die in der Seitenwand 6 gelagerten Zapfen tragen jeweils ein Stirnrad 8 bis 11, mit dem die Zylinder 1.1, 1.2, 2.1, 2.2 mit dem jeweils benachbarten Zylinder in Antriebsverbindung stehen. Somit werden vom Elektromotor 7 (in Fig. 1 folgend symbolisch durch Schraffur dargestellt) alle vier Zylinder angetrieben.In the FIGS. 1 to 4 Pressure units are shown, which are each driven by a separate, angle-controlled electric motor. In Fig. 1 The printing unit contains two printing units 3, 4 each formed by a forme cylinder 1.1, 1.2 and a transfer cylinder 2.1, 2.2. Each molding and transfer cylinder 1.1, 1.2, 2.1, 2.2 is mounted with its pins in side walls 5, 6 ( Fig. 5 ). On the operating side wall 5, an angle-controlled electric motor 7 is arranged, which drives the forme cylinder 1.1. About the formation of this drive connection statements are made later. The journals mounted in the side wall 6 each carry a spur gear 8 to 11, with which the cylinders 1.1, 1.2, 2.1, 2.2 are in drive connection with the respectively adjacent cylinder. Thus, the electric motor 7 (in Fig. 1 following symbolically represented by hatching) all four cylinders driven.

In Fig. 2 ist die in Fig. 1 dargestellte Druckeinheit um das Druckwerk 12 mit dem Formzylinder 1.3 und dem Übertragungszylinder 2.3 ergänzt. Das Druckwerk 12 ist an das Druckwerk 4 angesetzt, wobei, nicht dargestellt, die antriebsseitigen Zapfen ebenfalls Stirnräder tragen und das Stirnrad des übertragungszylinders 2.3 mit dem Stirnrad 11 des übertragungszylinders 2.2 in Eingriff steht.In Fig. 2 is the in Fig. 1 illustrated printing unit to the printing unit 12 with the forme cylinder 1.3 and the transfer cylinder 2.3 added. The printing unit 12 is attached to the printing unit 4, wherein, not shown, the drive-side pin also carry spur gears and the spur gear of the transfer cylinder 2.3 with the spur gear 11 of the transfer cylinder 2.2 is engaged.

über diese Stirnräder 8 bis 11 stehen also alle Zylinder mit dem Formzylinder 1.1 in Antriebsverbindung und werden vom Elektromotor 7 angetrieben.Thus, all cylinders are in drive connection with the forme cylinder 1. 1 via these spur wheels 8 to 11 and are driven by the electric motor 7.

In Fig. 3 sind zu den Druckwerken 3, 4 gemäß Fig. 1 die zusammenarbeitenden Druckwerke 13, 14 mit den Formzylindern 1.4, 1.5 und den Übertragungszylindern 2.4, 2.5 hinzugekommen. Nicht dargestellt trägt jeder antriebsseitige Zapfen der Zylinder 1.4, 1.5, 2.4, 2.5 ein Stirnrad, mit dem die Zylinder untereinander in Eingriff stehen. Weiterhin steht das Stirnrad 11 des Übertragungszylinders 2.2 über eine Räderkette 15 mit dem Stirnrad des übertragungszylinders 2.5 in Antriebsverbindung, so daß sämtliche Zylinder vom Elektromotor 7 angetrieben werden.In Fig. 3 are to the printing units 3, 4 according to Fig. 1 the cooperating printing units 13, 14 with the form cylinders 1.4, 1.5 and the transfer cylinders 2.4, 2.5 added. Not shown carries each drive-side pin of the cylinder 1.4, 1.5, 2.4, 2.5 a spur gear with which the cylinders are engaged with each other. Furthermore, the spur gear 11 of the transfer cylinder 2.2 via a gear chain 15 with the spur gear of the transfer cylinder 2.5 in drive connection, so that all cylinders are driven by the electric motor 7.

Die Druckeinheit gemäß Fig. 4 ist gegenüber Fig. 3 noch um einen Satellitenzylinder 16 ergänzt. Dieser trägt am antriebsseitigen Zapfen, nicht dargestellt, ein Stirnrad. Auf letzteres sowie auf das Stirnrad des Formzylinders 1.4 treibt eine vom Stirnrad 8 des Formzylinders 1.1 ausgehende Räderkette 17, so daß alle Zylinder der Druckeinheit vom Elektromotor 7 angetrieben werden.The printing unit according to Fig. 4 is opposite Fig. 3 supplemented by a satellite cylinder 16. This carries on the drive-side pin, not shown, a spur gear. On the latter and on the spur gear of the forme cylinder 1.4 drives a sprocket 17 outgoing from the spur gear 8 of the forme cylinder 1.1, so that all cylinders of the pressure unit are driven by the electric motor 7.

Bei den folgenden Figuren 6 bis 20 werden bei wiederkehrenden räumlichen Anordnungen von. Zylindern und Druckwerken aus den beschriebenen Figuren 1 bis 5 der Einfachheit halber deren Positionsnummern wieder verwendet, ungeachtet etwaiger baulicher Unterschiede. Die Figuren 6, 7 und 10 zeigen Brücken, d. h. Teile von Druckeinheiten, die mit den in den Figuren 1, 2 und 5 beschriebenen Druckeinheiten übereinstimmen und deshalb nicht nochmals näher erläutert werden.At the following FIGS. 6 to 20 are used in recurring spatial arrangements of. Cylinders and printing units from the described FIGS. 1 to 5 for simplicity, their position numbers reused, regardless of any structural differences. The FIGS. 6, 7 and 10 show bridges, ie parts of pressure units, with the in the FIGS. 1, 2 and 5 match described printing units and therefore will not be explained again.

In Fig. 8 ist gegenüber Fig. 3 die Räderkette 15 entfallen. Die entstehende untere Druckwerkbrücke (Doppeldruckwerk) mit den Formzylindern 1.1 und 1.2 und den übertragungszylindern 2.1 und 2.2 wird in gleicher Art, wie bei den Figuren 6 und 7 angetrieben. Die entstehende obere Druckwerkbrücke mit den Formzylindern 1.4, 1.5 und den Übertragungszylindern 2.4, 2.5 wird von einem winkelgeregelten Elektromotor 7 angetrieben, der am Formzylinder 1.4 angreift. Letzterer treibt über nicht dargestellte Stirnräder auf den Zapfen der Zylinder 1.4, 2.4, 2.5, 1.5 diese an.In Fig. 8 is opposite Fig. 3 the wheel chain 15 accounts. The resulting lower printing unit bridge (double printing unit) with the cylinders 1.1 and 1.2 and the transfer cylinders 2.1 and 2.2 is in the same manner as in the FIGS. 6 and 7 driven. The resulting upper printing unit bridge with the form cylinders 1.4, 1.5 and the transfer cylinders 2.4, 2.5 is driven by an angle-controlled electric motor 7, which engages the forme cylinder 1.4. The latter drives not shown spur gears on the journal of the cylinder 1.4, 2.4, 2.5, 1.5 this.

Bei Fig. 9 ist der Sachverhalt ähnlich zur Fig. 8. Es wird lediglich noch vom Formzylinder 1.1 ein Satellitenzylinder 16 mittels der Räderkette 18 angetrieben. Gleich- oder verschiedenartige Druckwerkbrücken der Figuren 6 bis 9 können zu verschiedenen Druckeinheiten kombiniert werden. Dabei können auch die nachfolgend noch beschriebenen Antriebsfälle zur Anwendung kommen.at Fig. 9 is the situation similar to Fig. 8 , It is only driven by the forme cylinder 1.1 a satellite cylinder 16 by means of the wheel chain 18. Same or different printing bridges of the FIGS. 6 to 9 can be combined to different pressure units. The drive cases described below can also be used.

Bei den bisher beschriebenen Ausführungsbeispielen kann auch jeder andere Form-, übertragungs- oder der Satellitenzylinder vom Elektromotor angetrieben werden.In the embodiments described so far, any other form, transmission or satellite cylinder can be driven by the electric motor.

Das in Fig. 11 gezeigte Doppeldruckwerk enthält die Druckwerke 3, 4 mit jeweils einem Formzylinder 1.1, 1.2 und einem Übertragungszylinder 2.1, 2.2. Diese Zylinder sind gleichermaßen in Seitenwänden 5, 6 gelagert (Fig. 15), wie bei den Figuren 1 und 6. Es wird jedoch jedes Druckwerk 3, 4 von einem eigenen winkelgeregelten Elektromotor 7 angetrieben, und zwar wird jeweils der Formzylinder 1.1 bzw. 1.2 angetrieben. Die antriebsseitigen Zapfen der Formzylinder 1.1, 1.2 tragen jeweils ein Stirnrad 8, 19, mit dem sie mit jeweils einem Stirnrad 10, 20 auf den Zapfen der Übertragungszylinder 2.1, 2.2 kämmen. Die Stirnräder 8, 10 und 19, 20 liegen in zwei verschiedenen Ebenen, da die übertragungszylinder 2.1, 2.2 nicht miteinander in Antriebsverbindung stehen dürfen. An den bedienseitigen Zapfen der Formzylinder 1.1, 1.2 greift jeweils ein winkelgeregelter Elektromotor 7 an und treibt die Druckwerke 3, 4 an.This in Fig. 11 shown double printing unit contains the printing units 3, 4, each with a forme cylinder 1.1, 1.2 and a transfer cylinder 2.1, 2.2. These cylinders are equally mounted in side walls 5, 6 ( Fig. 15 ), like the FIGS. 1 and 6 , However, each printing unit 3, 4 is driven by its own angle-controlled electric motor 7, and that in each case the forme cylinder 1.1 or 1.2 is driven. The drive-side pins of the forme cylinder 1.1, 1.2 each carry a spur gear 8, 19, with which they each with a spur gear 10, 20 on the pin of the Transfer cylinder 2.1, 2.2 comb. The spur gears 8, 10 and 19, 20 are in two different levels, since the transmission cylinder 2.1, 2.2 must not be in driving connection with each other. At the operator-side pin of the forme cylinder 1.1, 1.2 each engages an angle-controlled electric motor 7 and drives the printing units 3, 4 at.

Bei den bisherigen und noch folgenden Ausführungsbeispielen treiben die Elektromotoren jeweils die Formzylinder an. Statt dessen ist es auch möglich, die Übertragungszylinder anzutreiben. Als solches Beispiel treiben bei der Druckeinheit gemäß Fig. 12 die Elektromotoren 7 jeweils den Übertragungszylinder 2.1, 2.2, 2.3 der Druckwerke 3, 4, 12 an. Von diesen erfolgt dann mittels Stirnräder der Antrieb des jeweils zugehörigen Formzylinders 1.1, 1.2, 1.3. Analog zu Fig. 15 dürfen die Stirnräder des Druckwerks 4 und des Druckwerks 3 nicht in einer Ebene liegen, ebenso nicht die Stirnräder der Druckwerke 4 und 12.In the previous and still following embodiments, the electric motors each drive the form cylinder. Instead, it is also possible to drive the transfer cylinders. As such, drive in the printing unit according to Fig. 12 the electric motors 7 in each case the transfer cylinder 2.1, 2.2, 2.3 of the printing units 3, 4, 12 at. Of these, then by means of spur gears, the drive of the respective associated forme cylinder 1.1, 1.2, 1.3. Analogous to Fig. 15 the spur gears of the printing unit 4 and the printing unit 3 may not lie in one plane, nor the spur gears of the printing units 4 and 12th

Bei der Druckeinheit gemäß Fig. 13 werden die Formzylinder 1.1, 1.2, 1.4, 1.5 der Druckwerke 3, 4, 13, 14 von jeweils einem winkelgeregelten Elektromotor 7 angetrieben. Von diesen wird mittels Stirnräder der jeweils zugehörige Übertragungszylinder 2.1, 2.2, 2.4, 2.5 angetrieben. Die Stirnradtriebe zusammenarbeitender Druckwerke liegen jeweils in zwei verschiedenen Ebenen.In the printing unit according to Fig. 13 The forme cylinders 1.1, 1.2, 1.4, 1.5 of the printing units 3, 4, 13, 14 are each driven by an angle-controlled electric motor 7. Of these, the respective associated transfer cylinder 2.1, 2.2, 2.4, 2.5 is driven by spur gears. The spur gears of cooperating printing units each lie in two different planes.

Analog zu Fig. 13 erfolgt bei Fig. 14 der Antrieb der Druckwerke 3, 4, 13, 14. Zusätzlich wird der Satellitenzylinder 16 von einem separaten, winkelgeregelten Elektromotor 7 angetrieben.Analogous to Fig. 13 takes place at Fig. 14 In addition, the satellite cylinder 16 is driven by a separate, angle-controlled electric motor 7.

Bei den Druckeinheiten gemäß den Figuren 16 bis 19 wird jeder Formzylinder 1.1 bis 1.5 und jeder Übertragungszylinder 2.1 bis 2.5 und, soweit vorhanden, der Satellitenzylinder 16 von jeweils einem separaten, winkelgeregelten Elektromotor 7 angetrieben. Die Lagerung der Zylinder erfolgt wie bei den vorherigen Ausführungsbeispielen in den Seitenwänden 5, 6. Abweichend gegenüber den bisherigen Ausführungsbeispielen sind aber die Elektromotoren 7 jeweils am Zapfen der sogenannten Antriebsseite S 2 angeordnet (Fig. 20). Ebenso könnten die Elektromotoren auch an den bedienseitigen Zapfen angebracht sein. Auch könnten bei den vorangegangenen Ausführungsbeispielen die Elektromotoren 7 an den antriebsseitigen Zapfen angebracht sein. Bei der Ausstattung eines jeden Druckwerkes mit einem eigenen Antriebsmotor (Fig. 11 bis 14) können die einzelnen Druckwerke abwicklungsgerecht gut zueinander abgestimmt angetrieben werden. Beim separaten Antrieb eines jeden Zylinders (Figuren 16 bis 19) ist der abwicklungsgerechte Antrieb sogar zwischen Form- und Übertragungszylinder 1, 2 eines Druckwerkes möglich. Außerdem entfallen sämtliche Zahnradtriebe und die ansonsten dafür erforderlichen Schmierungen, Getriebekapselungen usw., wodurch enorme Kosteneinsparungen zu verzeichnen sind. Außerdem entfallen für gewünschte Druckwerksansteuerungen mechanische (und elektrische) Einrichtungen, da dies durch Drehrichtungsumkehr der antreibenden Motoren bewerkstelligt wird.In the printing units according to the FIGS. 16 to 19 Each cylinder 1.1 to 1.5 and each transfer cylinder 2.1 to 2.5 and, if present, the satellite cylinder 16 is driven by a separate, angle-controlled electric motor 7. The bearing of the cylinder takes place as in the previous embodiments in the side walls 5, 6. Deviating from the previous embodiments but the electric motors 7 are each arranged on the pin of the so-called drive side S 2 ( Fig. 20 ). Likewise, the electric motors could also be attached to the user-side pin. Also, in the foregoing embodiments, the electric motors 7 could be attached to the drive-side pin. When equipping each printing unit with its own drive motor ( Fig. 11 to 14 ), the individual printing units can be driven well matched to each other in terms of development. With separate drive of each cylinder ( FIGS. 16 to 19 ) is the development-oriented drive even between form and transfer cylinders 1, 2 of a printing unit possible. In addition, eliminates all gear drives and the otherwise required lubrication, gear encapsulations, etc., which are enormous cost savings. In addition, omitted for desired printing unit controls mechanical (and electrical) facilities, as this is accomplished by reversing the direction of rotation of the driving motors.

In den Ausführungsbeispielen enthält ein Druckwerk immer einen Form- und einen übertragungszylinder und arbeitet mit einem ebensolchen Druckwerk im Gummi-Gummi-Prinzip oder mit einem Satellitenzylinder zusammen. Ein solches Druckwerk kann auch mit einem Gegendruckzylinder zu einem Dreizylinderdruckwerk ergänzt werden, wobei jeder Zylinder von einem separaten Elektromotor angetrieben wird oder nur ein Zylinder von einem Elektromotor angetrieben wird und die drei Zylinder über Zahnräder in Antriebsverbindung stehen.In the embodiments, a printing unit always contains a forming and a transfer cylinder and works with a similar printing unit in rubber-rubber principle or with a satellite cylinder together. Such a printing unit can also be supplemented with a counter-pressure cylinder to a three-cylinder printing unit, wherein each cylinder is driven by a separate electric motor or only one cylinder is driven by an electric motor and the three cylinders are in driving connection via gears.

Die Winkelregelung der Elektromotoren erfolgt mittels Rechner-Motorregelungen im Rahmen der Maschinensteuerung. Entsprechend sind die Motoren mit diesen Systemen verbunden. Die Regelungen sind aber nicht Gegenstand der Erfindung, so daß Darstellungen und Erklärungen hierzu nicht erfolgen.The angular control of the electric motors by means of computer engine controls within the machine control. Accordingly, the motors are connected to these systems. However, the regulations are not the subject of the invention, so that representations and explanations do not occur.

Mit separaten Elektromotoren lassen sich vorteilhaft auch weitere Funktionsgruppen von Druckmaschinen antreiben. In Fig. 21 ist eine Druckmaschine in der Seitenansicht und in Fig. 22 eine Falzeinheit in der Ansicht mit derartigen Funktionsgruppen gezeigt. Die Druckmaschine gemäß Fig. 21 enthält vier Druckeinheiten 21 bis 24 und eine Falzeinheit 25. Die Druckeinheiten 23 und 24 ähneln antriebsmäßig der in Fig. 17 gezeigten Druckeinheit, die Druckeinheiten 21 und 22 ähneln der in Fig. 18 gezeigten. Die Antriebsmotoren der Zylinder wie auch der nachfolgend noch beschriebenen Funktionsgruppen sind symbolisch mit einem "M" oder Schraffur gekennzeichnet. Die in Fig. 22 gezeigte Falzeinheit enthält die Falzwerke 26 und 27. In Fig. 21 sind die Einzugwerke 28, die Kühlwalzen 29, die Schneidwalzen 30 und die Trichterwalzen 31 von jeweils einem separaten, winkelgeregelten Elektromotor 33.1 bis 33.5 angetrieben. Die Elektromotoren treiben dabei indirekt über Riemen die Zylinder dieser Funktionsgruppen an. Fig. 21.1 zeigt die gleiche Druckmaschine, wobei jeder Zylinder dieser Funktionsgruppen direkt von einem Motor angetrieben wird.With separate electric motors can be advantageous also drive more functional groups of printing presses. In Fig. 21 is a printing press in the side view and in Fig. 22 a folding unit in the view shown with such functional groups. The printing machine according to Fig. 21 includes four printing units 21 to 24 and a folding unit 25. The printing units 23 and 24 are drivingly similar in Fig. 17 shown printing unit, the printing units 21 and 22 are similar to the in Fig. 18 shown. The drive motors of the cylinders as well as the function groups described below are symbolically marked with an "M" or hatching. In the Fig. 22 shown folding unit includes the folding units 26 and 27. In Fig. 21 the infeeds 28, the cooling rollers 29, the cutting rollers 30 and the hopper rollers 31 are each driven by a separate, angle-controlled electric motor 33.1 to 33.5. The electric motors indirectly drive the cylinders of these functional groups via belts. Fig. 21.1 shows the same printing press, where each cylinder of these functional groups is driven directly by a motor.

In Fig. 22 werden die Trichterwalzen 31 und die Zug- und Überführwalzen 32 von jeweils einem separaten, winkelgeregelten Elektromotor direkt angetrieben. Auch die beiden Falzwerke 26 und 27 besitzen jeweils einen separaten, winkelgeregelten Motor, der jeweils einen Falzzylinder, hier den Messerzylinder 143, 144, direkt antreibt. Mit diesem Zylinder stehen die anderen Falzzylinder über auf ihren Zapfen angeordneten Stirnrädern in Eingriff.In Fig. 22 For example, the funnel rollers 31 and the pull and transfer rollers 32 are each directly driven by a separate angle-controlled electric motor. Also, the two folding units 26 and 27 each have a separate, angle-controlled motor, each of which drives a folding cylinder, here the knife cylinder 143, 144, directly. With this cylinder, the other folding cylinders are engaged by spur gears disposed on their spigots.

Bei der Falzeinheit gemäß Fig. 22.1 werden die Trichterwalzen 31 und die Zug- und Überführwalzen 32 von jeweils einem gemeinsamen Motor indirekt über einen Zahnriemen angetrieben. Auch das einzige Falzwerk 27.1 wird von einem separaten, winkelgeregelten Elektromotor angetrieben. Der Antrieb erfolgt indirekt mittels Riementriebes auf beispielsweise den Punktur-Falzmesser-Zylinder 145. Mit diesem stehen die anderen Falzzylinder mit ihren Zylinderrädern in Antriebsverbindung. Mit diesen Elektromotoren ist eine feinfühlige Einstellung der Drehzahl der angetriebenen Zylinder möglich. Bei Gruppen mit Voreilungsregelung ist dann auch entsprechend feinfühlig die Bahnspannung einstellbar. Auch ergeben sich große Kostenvorteile durch den Entfall der für derartige Antriebe bisher üblichen PIV-Getriebe.In the folding unit according to Fig. 22.1 For example, the funnel rollers 31 and the pull and transfer rollers 32 are each indirectly driven by a timing belt by a common motor. Also, the single folding unit 27.1 is driven by a separate, angle-controlled electric motor. The drive takes place indirectly by means of belt drive on, for example, the puncturing folding blade cylinder 145. With this are the other folding cylinders with their cylindrical gears in drive connection. With these electric motors, a sensitive adjustment of the rotational speed of the driven cylinder is possible. For groups with overfeed control, the web tension is then also correspondingly sensitive adjustable. Also, there are major cost advantages through the elimination of the usual for such drives PIV transmission.

Der direkt auf einen Formzylinder treibende separate Elektromotor ist auch vorteilhaft als Stellglied für die Farbregisterverstellung nutzbar. Fig. 23 zeigt eine Vorrichtung zur Farbregisterverstellung bei einem Doppeldruckwerk mit den Druckwerken 34 und 35, die jeweils einen Formzylinder 36, 38 und einen übertragungszylinder 37, 39 enthalten. Die Vorrichtung wird anhand des Formzylinders 38 beschrieben, der am Umfang zwei Druckformen trägt. Der den Formzylinder 38 antreibende Elektromotor 40 wird von einer Rechner-Motorregelung 41 winkelgeregelt. Weiterhin wird ein Stellungsgeber 42 des Druckwerkes 35 und ein die Registermarken auf der das Druckwerk 35 verlassenden Bahn 43 abtastender Meßwertgeber 44 auf eine Vergleichseinrichtung 45 geschaltet, deren Ausgang auf den Eingang der Rechner-Motorregelung 41 geführt ist. Der Meßwertgeber 44 tastet die vom Druckwerk 35 auf die Bahn 43 gedruckten Registermarken ab und ermittelt so die Position der beiden Bilder, die pro Umdrehung des Formzylinders gedruckt werden. Mit dem Signal des Stellungsgebers 42 wird in der Vergleichseinrichtung 45 der Bezug zur Umdrehung des Formzylinders 38 hergestellt. Bei einer versetzten Anordnung eines Druckbildes in Umfangsrichtung zum halben Umfang des Formzylinders, d. h. bei einer vom halben Umfang abweichenden Anordnung des Druckbildes, wird der Formzylinder 38 vor dem Drucken in diesem Bereich mit einer ausgleichenden Vor- oder Nacheilung betrieben. Dies wird mittels der Rechner-Motorregelung entsprechend dem Ausgangssignal der Vergleichseinrichtung 45 bewerkstelligt. Hiermit können beispielsweise Kopierfehler oder Montagefehler der Druckform ausgeglichen werden. Unter Inkaufnahme gewisser Abstriche an die Passerqualität am Druckanfang kann die Beschleunigungs- oder Verzögerungsphase auch bis in diesen Bereich ausgedehnt werden, wodurch der Elektromotor mit niedrigerer Leistung dimensioniert werden kann.The direct on a form cylinder driving separate electric motor is also beneficial as an actuator for the color register adjustment available. Fig. 23 shows a device for color register adjustment in a double printing unit with the printing units 34 and 35, each containing a forme cylinder 36, 38 and a transfer cylinder 37, 39. The device will be described with reference to the forme cylinder 38, which carries two pressure forms on the circumference. The forme cylinder 38 driving electric motor 40 is angle-controlled by a computer engine control 41. Furthermore, a position transmitter 42 of the printing unit 35 and a register marks on the printing unit 35 leaving web 43 scanning sensor 44 is connected to a comparator 45 whose output is fed to the input of the computer engine control 41. The transmitter 44 scans the register marks printed by the printing unit 35 on the web 43 and thus determines the position of the two images which are printed per revolution of the forme cylinder. With the signal of the position sensor 42, the reference to the rotation of the forme cylinder 38 is produced in the comparison device 45. In a staggered arrangement of a printed image in the circumferential direction to half the circumference of the forme cylinder, ie at a deviating from half the circumference arrangement of the printed image, the forme cylinder 38 is operated before printing in this area with a compensatory lead or lag. This is done by means of the computer engine control according to the output signal of the comparator 45. This can, for example, copying errors or assembly errors of the printing form be compensated. By accepting certain deductions to the registration quality at the beginning of printing, the acceleration or deceleration phase can also be extended into this area, as a result of which the electric motor can be dimensioned with lower power.

Die in Fig. 24 gezeigte Vorrichtung dient der Regelung des Umfangsregisters zwischen zwei Druckstellen, hier zwischen Druckwerk 46 und 47. Die von diesen Druckwerken 46, 47 auf die Bahn 48 gedruckten Passermarken werden von Meßwertgebern 49, 50 abgetastet. Die Signale der Meßwertgeber 49, 50 werden in die Vergleichseinrichtung 51 geleitet. Diese gibt das Vergleichsergebnis an die Rechner-Motorregelung 52. Diese regelt die Drehzahl des den Formzylinder 53 des Druckwerkes 47 antreibenden Elektromotors 54. Je nach erforderlicher Passeränderung zum Druckbild des Druckwerkes 46 wird der Elektromotor 54 mit Vor- oder Nacheilung betrieben. Falls auch der übertragungszylinder 55 von einem separaten Elektromotor angetrieben wird, wird auch dieser bei einer Passerkorrektur vorteilhaft hinsichtlich seiner Drehzahl korrigiert. Die Vorrichtung ist entsprechend der Anzahl der zu kontrollierenden Passer entsprechend vielfach oder entsprechend voll erweitert anzuwenden. Mit der Vorrichtung können die traditionellen kostspieligen mechanischen Getriebe z. B. Schieberäder, zur Umfangsregisterverstellung der Formzylinder eingespart werden.In the Fig. 24 The apparatus shown serves to regulate the circumferential register between two printing locations, here between printing unit 46 and 47. The registration marks printed by these printing units 46, 47 on the web 48 are scanned by transducers 49, 50. The signals of the transducers 49, 50 are passed into the comparator 51. This regulates the speed of the electric motor 54 driving the forme cylinder 53 of the printing unit 47. Depending on the required registration change to the print image of the printing unit 46, the electric motor 54 is operated with lead or lag. If the transmission cylinder 55 is also driven by a separate electric motor, this is also advantageously corrected for a speed correction in terms of its rotational speed. The device is according to the number of passport to be controlled according to multiple or fully extended accordingly apply. With the device, the traditional expensive mechanical transmission z. B. sprockets, for circumferential register adjustment of the form cylinder can be saved.

Dank des Einzelantriebes der Druckwerke können auch unterschiedliche Papierwege zwischen verschiedenen Druckeinheiten ohne das Erfordernis zusätzlicher Einrichtungen zur Längenregulierung gefahren werden. Bei der in Fig. 21 gezeigten Druckmaschine beispielsweise kann die Bahn 55 von der Druckeinheit 23 entweder zur Druckeinheit 21 oder auf dem gestrichelt gezeichneten Weg zur Druckeinheit 22 geführt werden. Entsprechend dem unterschiedlichen Weg werden die Druckwerke der Druckeinheiten 21 und 22 mittels ihrer Antriebsmotoren in die erforderliche Position gefahren. Hierzu ist die Rechner-Motorregelung 56 der Elektromotoren eingangsseitig mit einer Rechen- und Speichereinheit 57 verbunden, in der die erforderlichen Zylinderpositionen abgespeichert sind. Diese werden je nach Bahnlauf der Rechner-Motorregelung 56 vorgegeben, die die Form- und Übertragungszylinder durch entsprechende Ansteuerung ihrer Elektromotoren in die erforderlichen Positionen fährt.Thanks to the single drive of the printing units and different paper paths between different printing units can be driven without the need for additional devices for length control. At the in Fig. 21 For example, the web 55 may be guided by the printing unit 23 either to the printing unit 21 or on the dashed path to the printing unit 22 shown printing machine. According to the different way the printing units of the printing units 21 and 22 are driven by their drive motors in the required position. For this purpose, the computer engine control 56 of the electric motors is connected on the input side to a computing and storage unit 57, in which the required cylinder positions are stored. These are given depending on the web run of the computer motor control 56, which drives the form and transfer cylinder by appropriate control of their electric motors in the required positions.

Außerdem enthält die Rechen- und Speichereinheit 57 für die möglichen Bahnläufe die Zylinderpositionen der Druckwerke für das Schnittregister gespeichert. Zur Schnittregistereinstellung werden entsprechend der gewählten Produktionskonfiguration der Rechner-Motorregelung 56 die erforderlichen Zylinderpositionen vorgegeben. Entsprechend der Vorgabe verstellt die Rechner-Motorregelung 56 die Antriebsmotore aller die Bahn 55 bedruckenden Druckwerke. Das Schnittregister zum Schnitt im Falzwerk wird also über die Zylinderpositionen aller am Druck beteiligten Druckwerke eingestellt. Es entfallen damit die bisher üblichen, kostenaufwendigen Linearregistereinrichtungen. Lediglich für den Wendestrang ist noch eine derartige Längenregulierung notwendig. Die die Zylinderpositionen für das Schnittregister enthaltende Rechen- und Speichereinheit kann auch auf die Rechner-Motorregelung 66 der in Fig. 25 gezeigten, nachfolgend beschriebenen Vorrichtung geführt sein, wobei diese Vorrichtung dann sowohl der Schnittregisterregelung als auch -verstellung dient.In addition, the possible web path calculating and storage unit 57 stores the cylinder positions of the printing units for the cut register. For cutting register setting the required cylinder positions are given according to the selected production configuration of the computer engine control 56. According to the specification, the computer motor control 56 adjusts the drive motors of all the webs 55 printing printing units. The cut register for the cut in the folding unit is thus set via the cylinder positions of all printing units involved in the printing. It eliminates the hitherto customary, costly Linearregistereinrichtungen. Only for the turning strand is still such a length adjustment necessary. The arithmetic and memory unit containing the cylinder positions for the cut register can also be applied to the computer motor control 66 of the Fig. 25 shown device, described below, this device then serves both the cut register control and adjustment.

Dank den separaten Antrieben der Druckwerke können auch unter Entfall bisher üblicher Verbindungselemente, wie Synchronwellen, Kupplungen, Getriebe und Positioniereinrichtungen, Druckmaschinenverbände variabel zusammengestellt werden. über ein entsprechendes Steuerungsprogramm können z. B. die gemäß Figur 21 der Falzeinheit 25 zugeschalteten Druckeinheiten 21, 22, 23 oder einige dieser Druckeinheiten auch einer nicht dargestellten anderen Falzeinheit zugeordnet werden.Thanks to the separate drives of the printing units can be put together variably under elimination of previously common fasteners, such as synchronous shafts, clutches, gearboxes and positioning, printing press associations. About a corresponding control program can z. B. according to FIG. 21 the folding unit 25 connected printing units 21, 22, 23 or some of these printing units are also assigned to a different folding unit, not shown.

Fig. 25 zeigt eine Vorrichtung zur Schnittregisterregelung. Es bedrucken beispielsweise die Druckwerke 58 bis 61 eine Bahn 62. Ein Meßwertgeber 63 tastet eine mitgedruckte Registermarke ab. Der Meßwertgeber 63 sowie der Stellungsgeber 64 eines Elektromotors einer durchfahrenen Druckeinheit, vorteilhaft der ersten durchfahrenen Druckeinheit 59, sind auf die Eingänge einer Vergleichseinrichtung 65 geschaltet, die ausgangsseitig mit dem Eingang der Rechner-Motorregelung der Elektromotoren der Druckwerke 58 bis 61 verbunden ist. Ein in der Vergleichseinrichtung 65 ermittelter Registerfehler wird durch voreilenden bzw. nacheilenden Antrieb der die Bahn 62 bedruckenden Druckwerke 58 bis 61 durch entsprechende Ansteuerung ihrer Elektromotoren mittels der Rechner-Motorregelung 66 ausgeregelt. Fig. 25 shows a device for cutting register control. For example, the printing units 58 to 61 are printed on a web 62. A transmitter 63 scans a printed register mark. The transmitter 63 and the position sensor 64 of an electric motor of a traversed pressure unit, advantageously the first traversed Pressure unit 59, are connected to the inputs of a comparator 65, the output side of which is connected to the input of the computer motor control of the electric motors of the printing units 58 to 61. A registration error determined in the comparison device 65 is compensated by leading or trailing drive of the webs 62 printing units 58 to 61 by appropriate control of their electric motors by the computer engine control 66.

Fig. 26 zeigt eine nicht beanspruchte Vorrichtung, mit Hilfe derer die Formzylinder in eine für den Formwechsel geeignete Stellung gefahren werden. Die Druckeinheit enthält zwei Druckwerke 67, 68 mit jeweils einem Formzylinder 69, 70 und einem übertragungszylinder 71, 72. Die Antriebsmotoren der Druckwerke 67, 68, die hier beispielsweise die Übertragungszylinder 71, 72 antreiben, stehen mit einer Rechner-Motorregelung 73 in Verbindung, die von einer Rechen- und Speichereinheit 74 gespeist wird. In die Rechen- und Speichereinheit 74 sind die Zylinderpositionen der Formzylinder 69, 70 für den Druckformwechsel eingespeichert. Diese Positionen werden der Rechner-Motorregelung 73 vorgegeben, die die Elektromotoren der Druckwerke 67, 68 der art ansteuert, daß die Spanngruben 75, 76 der Formzylinder 69, 70 auf kürzestem Wege in die Plattenwechselposition gefahren werden. Dabei ist es ebenso wie.bei den vorherigen Ausführungsbeispielen gleichgültig, ob bei einem Druckwerk der Übertragungs- oder der Formzylinder oder beide Zylinder angetrieben werden. Mit Hilfe dieser Vorrichtung entfällt das bisher übliche zeitaufwendige einzelne Auskuppeln der Druckwerke, das anschließende Positionieren der Druckwerke und deren Einkuppeln nach dem Druckformwechseln. Fig. 26 shows an unclaimed device by means of which the form cylinder are moved to a suitable position for the change of shape. The printing unit contains two printing units 67, 68, each with a forme cylinder 69, 70 and a transfer cylinder 71, 72. The drive motors of the printing units 67, 68, which for example drive the transfer cylinders 71, 72, are connected to a computer engine control 73. which is fed by a computing and storage unit 74. In the computing and storage unit 74, the cylinder positions of the forme cylinders 69, 70 are stored for the printing form change. These positions are the computer-motor control 73 predetermined, which controls the electric motors of the printing units 67, 68 of the art that the clamping holes 75, 76 of the forme cylinder 69, 70 are driven by the shortest route in the disk change position. It is just as wie.bei the previous embodiments, regardless of whether in a printing unit of the transfer or the form cylinder or both cylinders are driven. With the help of this device eliminates the hitherto usual time-consuming single disengagement of the printing units, the subsequent positioning of the printing units and their engagement after the printing form changes.

Vorteilhaft werden auch die Reibzylinder von Farb- und Feuchtwerken mit separaten Antrieben angetrieben. Fig. 27 zeigt ein Druckwerk mit einem Übertragungszylinder 77.1 und einem Formzylinder 78.1, wobei an letzterem ein Farbwerk 79.1 und eine Feuchtwerk 80.1 angeordnet sind. Das Farbwerk 79.1 enthält u. a. die Farbreibzylinder 81.1 und 82.1, und das Feuchtwerk 80.1 den Feuchtreibzylinder 83.1. Jeder Reibzylinder 81.1, 82.1, 83.1 trägt ein Stirnrad 84.1, 85.1, 86.1, die allesamt mit einem Zentralrad 87 in Eingriff stehen. Das Zentralrad 87 wird von einem winkelgeregelten Elektromotor 88 angetrieben. Im Ausführungsbeispiel befindet sich das Zentralrad 87, nicht dargestellt, auf dem Rotorzapfen des Elektromotors 88. Ebenso könnte der Elektromotor aber auch neben dem Zentralrad 87 angeordnet sein und mit einem Ritzel in dieses eingreifen. Der Elektromotor 88 treibt also beide Farbreibzylinder 81.1, 82.1 und den Feuchtreibzylinder 83.1 an.Advantageously, the distribution cylinders of inking and dampening units are also driven by separate drives. Fig. 27 shows a printing unit with a transfer cylinder 77.1 and a forme cylinder 78.1, wherein on the latter an inking 79.1 and a dampening 80.1 are arranged. The inking unit 79.1 contains, inter alia, the Farbreibzylinder 81.1 and 82.1, and the dampening unit 80.1 the dampening cylinder 83.1. Each distribution cylinder 81.1, 82.1, 83.1 carries a spur 84.1, 85.1, 86.1, all of which are in engagement with a central wheel 87. The central wheel 87 is driven by an angle-controlled electric motor 88. In the exemplary embodiment, the central wheel 87, not shown, is located on the rotor pin of the electric motor 88. Likewise, the electric motor could also be arranged next to the central wheel 87 and engage with a pinion in this. The electric motor 88 thus drives both Farbreibzylinder 81.1, 82.1 and the dampening cylinder 83.1.

In Fig. 28 werden die Farbreibzylinder 81.2 und 82.2 von einem winkelgeregelten Elektromotor 89 angetrieben. Der Feuchtreibzylinder 83.2 des Feuchtwerkes 80.2 wird von einem winkelgeregelten Elektromotor 90 angetrieben. Der Elektromotor 89 treibt direkt auf den Farbreibzylinder 82.2. Dieser trägt ein Stirnrad 85.2, mit dem er über ein Zwischenrad 91 auf ein Stirnrad 84.2 des Farbreibzylinders 81.2 treibt.In Fig. 28 the ink-jet cylinders 81.2 and 82.2 are driven by an angle-controlled electric motor 89. The dampening cylinder 83.2 of the dampening unit 80.2 is driven by an angle-controlled electric motor 90. The electric motor 89 drives directly on the Farbreibzylinder 82.2. This carries a spur gear 85.2, with which he drives via an intermediate gear 91 on a spur gear 84.2 of the inking 81.2.

Fig. 29 zeigt eine Antriebsvariante, wonach jeder Farbreibzylinder 81.3, 82.3 des Farbwerkes 79.3 und der Feuchtreibzylinder 83.3 des Feuchtwerkes 80.3 von einem separaten, winkelgeregelten Elektromotor 92, 93, 94 angetrieben wird. Bei diesem Antrieb des Farb- und Feuchtwerkes entfallen alle bisher hierfür üblichen Zahnräder. Fig. 29 shows a drive variant, according to which each Farbreibzylinder 81.3, 82.3 of the inking unit 79.3 and the dampening cylinder 83.3 of the dampening unit 80.3 by a separate, angle-controlled electric motor 92, 93, 94 is driven. In this drive of the inking and dampening all previously customary for this purpose gears omitted.

Neben der vorteilhaften Regelbarkeit der Drehzahl der Farbreibzylinder beim Antrieb mittels separater, winkelgeregelter Elektromotoren ist außerdem die seitliche Verreibung günstig gestaltbar. Fig. 30 zeigt die Seitenansicht der Farb- und Feuchtreibzylinder 81.3, 82.3, 83.3, die in Seitenwänden 95, 96 gelagert sind. An jeweils einem Zapfen 97 bis 99 dieser Zylinder 81.3 bis 83.3, die vorteilhaft als Rotor der antreibenden Elektromotoren 92 bis 94 ausgebildet sind, greift z. B. ein Linearmotor 100 bis 102 an. Die winkelgeregelten Elektromotoren 92 bis 94 werden von einer Rechner-Motorsteuerung 103, angesteuert. Die Motorsteuerung 103 steuert vorteilhaft die Linearmotoren 100 bis 102 mit einem gleichen Bewegungsablauf. Vorteilhaft ist hierfür ein sinusförmiger Verlauf der Changierbewegung, wobei die Reiberhübe zueinander um 120° in der Phasenlage versetzt sind. Es wird dadurch ein Massenausgleich erzielt, wodurch die Anregung von Schwingungen quer zur Maschinenachse ausgeschaltet wird. Der Sollwert des axialen Hubes wird vorteilhaft wählbar vorgegeben. Die momentane Position der Farbreiber 81.3, 82.3, 83.3 wird der Motorsteuerung von Sensoren 140 bis 142 rückgemeldet. Günstig ist auch die Auslegung der Changiergeschwindigkeit linear proportional zur Geschwindigkeit der Druckmaschine.In addition to the advantageous controllability of the speed of the inking cylinder in the drive by means of separate, angle-controlled electric motors also the lateral trituration can be designed low. Fig. 30 shows the side view of the ink and dampening cylinders 81.3, 82.3, 83.3, which are mounted in side walls 95, 96. At each one pin 97 to 99 of these cylinders 81.3 to 83.3, which are advantageously designed as a rotor of the driving electric motors 92 to 94, z. B. a linear motor 100 to 102 at. The angle-controlled electric motors 92 to 94 are controlled by a computer engine controller 103. The motor controller 103 advantageously controls the linear motors 100 to 102 with a same sequence of movements. For this purpose, a sinusoidal course of the traversing movement is advantageous, wherein the friction strokes are offset from each other by 120 ° in the phase position. It is achieved by a mass balance, whereby the excitation of vibrations is switched off across the machine axis. The desired value of the axial stroke is advantageously selected selectable. The current position of the ink driver 81.3, 82.3, 83.3 is the motor control of sensors 140 to 142 fed back. Conveniently, the design of the traversing speed is linearly proportional to the speed of the printing press.

Auch Kurzfarbwerke werden vorteilhaft mit separaten, beispielsweise winkelgeregelten Elektromotoren angetrieben. So können die Rasterwalze und die Farbauftragwalze gemeinsam von einem oder einzeln von jeweils einem Elektromotor angetrieben werden.Even short inking units are advantageously driven by separate, for example angle-controlled electric motors. Thus, the anilox roller and the inking roller can be driven in common by one or individually by an electric motor.

Für einen exakten Antrieb der Zylinder ist deren möglichst starre Kupplung mit dem Elektromotor wichtig. Nachfolgend werden konstruktive Ausführungsbeispiele hierfür gebracht. Fig. 31 zeigt einen Formzylinder 105, der mit seinen Zapfen 106, 107 in Seitenwänden 108, 109 der Druckmaschine lagert. Die Zapfen 106, 107 tragen Flansche 110, 111, mit denen sie an den Stirnseiten des Zylinderkörpers angeschraubt sind. Der Zapfen 106 ist als Rotor 112 des den Formzylinder antreibenden Elektromotors 113 ausgebildet, d. h. er trägt an seinem verlängerten Ende die Elemente des Rotors. Der Stator 114 ist an der Seitenwand 108 befestigt. Am Zapfen 106 greift weiterhin eine Vorrichtung zur seitlichen Verschiebung des Formzylinders 105 für die Seitenregisterverstellung an. Beispielsweise kommt hierfür ein Linearmotor 115 zur Anwendung. Es könnte z. B. auch ein Motor in Verbindung mit einem seiner Drehbewegung in eine geradlinige Bewegung umformenden Getriebe eingesetzt werden. Der Verschiebebetrag Z des Seitenregisters ist dabei so bemessen, daß bei beidseitigem Abrücken der Zapfen 106, 107 um jeweils Z/2 vom Formzylinderkörper dieser freigegeben wird und aus der Druckmaschine entnommen werden kann. Es ist sodann eine hülsenförmige Druckform des Formzylinders 105 wechselbar. In ähnlicher Art können auch Reibzylinder ausgeführt werden, wobei der Reiberhub zum Freilegen des Zylinderkörpers des Reibzylinders benutzt werden kann.For an exact drive of the cylinder whose rigid as possible coupling with the electric motor is important. Below are constructive embodiments brought this. Fig. 31 shows a plate cylinder 105, which supports with its pins 106, 107 in side walls 108, 109 of the printing press. The pins 106, 107 carry flanges 110, 111, with which they are screwed to the end faces of the cylinder body. The pin 106 is formed as a rotor 112 of the forme cylinder driving electric motor 113, that is, it carries at its extended end the elements of the rotor. The stator 114 is fixed to the side wall 108. At the pin 106 further engages a device for lateral displacement of the forme cylinder 105 for the side register adjustment. For example, a linear motor 115 is used for this purpose. It could be z. Example, a motor in conjunction with one of its rotary motion in a rectilinear motion transforming transmission can be used. The displacement amount Z of the side register is dimensioned so that when both sides of the peg 106, 107 to each Z / 2 from the forme cylinder body this is released and can be removed from the printing press. It is then a sleeve-shaped printing form of the forme cylinder 105 replaceable. In a similar manner, it is also possible to carry out distribution cylinders, wherein the transfer stroke can be used to expose the cylinder body of the distribution cylinder.

Fig. 32 zeigt den antriebsseitigen Teil eines Formzylinders 116, an dessen Zapfen 117 der Rotor 118 eines Elektromotors 119 stirnseitig angeschraubt ist. Der Stator 120 des Elektromotors 119 wird zusammen mit einer an ihm befestigten Büchse 121, die das Lager 122 des Formzylinders 116 enthält, in Lagerschilden 123, 124 aufgenommen. Fig. 32 shows the drive-side part of a forme cylinder 116, at the pin 117 of the rotor 118 of an electric motor 119 is screwed on the front side. The stator 120 of the electric motor 119 is accommodated in bearing plates 123, 124 together with a bushing 121 attached thereto, which contains the bearing 122 of the forme cylinder 116.

Die Lagerschilde 123, 124 sind auseinanderfahrbar und geben im auseinander gefahrenen Zustand eine Öffnung 125 der Seitenwand 126 der Druckmaschine frei. Durch die freigelegte Öffnung 125 ist dann eine hülsenförmige Druckform 139 hindurch auf den oder von dem Formzylinder 116 führbar. Die Kontur der hindurchgeführten Druckform 139 ist strichpunktiert angedeutet. Lösungen für die Ausführung und Betätigung der Lagerschilde 123, 124 sowie das Halten des Formzylinders 116 an seinem anderen Ende in der Schwebe bei freigelegter Öffnung 125 bietet der Stand der Technik, so daß darauf nicht näher eingegangen wird. Ebenso kann auch ein Übertragungszylinder freigelegt werden, und die Motorgestaltung ist gleichermaßen bei Übertragungszylindern und anderen Zylindern von Druckmaschinen anwendbar. Vorteilhaft ist bei den gezeigten Ausführungsmöglichkeiten auch, daß eine unabhängige Vormontage von Rotor und Stator des Elektromotors durchgeführt werden kann.The bearing plates 123, 124 can be moved apart and release an opening 125 of the side wall 126 of the printing press in the extended state. Through the exposed opening 125, a sleeve-shaped printing plate 139 can then be guided through onto or from the forme cylinder 116. The contour of the printing plate 139 guided through is indicated by dash-dotted lines. Solutions for the execution and operation of the end shields 123, 124 and the holding of the forme cylinder 116 at its other end in suspension with exposed opening 125 provides the state of the art, so that will not be discussed in detail. Likewise, a transfer cylinder may also be exposed, and the engine design is equally applicable to transfer cylinders and other cylinders of printing presses. It is also advantageous in the embodiments shown that an independent pre-assembly of rotor and stator of the electric motor can be performed.

Fig. 33 zeigt die Befestigung des Stators 127 eines Elektromotors 128 am Exzenterring 129 eines Drei-Ring-Lagers 130 eines in der Seitenwand 131 gelagerten Zylinders. Es kann sich hierbei beispielsweise um einen Übertragungszylinder handeln, von dem nur der Zapfen 132 gezeigt ist. Durch Verdrehen des exzentrischen Lagerringes 129 kann beispielsweise die Druckan- und Druckabstellung erfolgen. Durch diese Befestigung des Stators 127 erfolgt vorteilhaft dessen Mitführung bei der An- und Abstellbewegung des Zapfens mitsamt dem auf ihm befestigten Rotor 133. Im einzelnen ist der Stator 127 an einem Flansch 134 befestigt der am Lagerring 129 angeschraubt ist. Der Flansch 134 wird mit Niederhaltern 135 an der Seitenwand 131 axial fixiert und nimmt das Kippmoment aus der Gewichtskraft des Stators auf. Die Betätigung des Lagerrings 129 ist in Fig. 34 gezeigt. Der Lagerring 129 trägt eine Nabe 136, an der der Druckan- und -abstellmechanismus, beispielsweise ein Hebel 137, angreift. In der Druckanstellung schlägt der Lagerring 129 vorteilhaft an einem gestellfesten, günstigerweise einstellbaren Anschlag 138 an und nimmt so, die entsprechende Drehrichtung des Zylinders vorausgesetzt, das Gegenmoment des Stators 127 auf. Bei anderer Drehrichtung des Zylinders nimmt der kräftig dimensionierte Druckan- und abstellmechanismus das Gegenmoment auf. Vorteilhaft ist die Zylinderlagerung spielfrei ausgeführt. Fig. 33 shows the attachment of the stator 127 of an electric motor 128 on the eccentric ring 129 of a three-ring bearing 130 of a cylinder mounted in the side wall 131. This may be, for example, a transfer cylinder, of which only the pin 132 is shown. By turning the eccentric bearing ring 129, for example, the pressure and Druckabstellung done. By this attachment of the stator 127 is advantageously carried along in the arrival and Abstellbewegung of the pin together with the rotor 133 mounted on it. In detail, the stator 127 is attached to a flange 134 which is screwed to the bearing ring 129. The flange 134 is axially fixed with downers 135 on the side wall 131 and receives the tilting moment from the weight of the stator. The operation of the bearing ring 129 is in Fig. 34 shown. The bearing ring 129 carries a hub 136 to which the Druckan- and Abstellmechanismus, for example, a lever 137 engages. In the pressure position, the bearing ring 129 advantageously abuts against a frame-fixed, suitably adjustable stop 138 and, assuming the corresponding direction of rotation of the cylinder, assumes the counter-torque of the stator 127. In another direction of rotation of the cylinder takes the strongly dimensioned pressure on and Abstellmechanismus on the counter-torque. Advantageously, the cylinder bearing is designed without play.

In den Ausführungsbeispielen kommen winkelgeregelte Elektromotoren für den Antrieb der Zylinder und Funktionsgruppen zum Einsatz. Unter Benutzung der Erfindung können bei Antriebsfällen mit nicht zu hohen Anforderungen an den Gleichlauf, wie Antrieb von Bahnzugelementen und Reibzylindern, auch drehzahl- oder momentgeregelte Elektromotoren zur Anwendung kommen. Auch die angewandten Rechner-Motorregelungen können von Fall zu Fall durch andere Motorregelungen realisiert werden.In the embodiments, angle-controlled electric motors are used for driving the cylinders and functional groups. Using the invention can be used in drive cases with not too high demands on the synchronization, such as drive train of track elements and friction cylinders, speed or torque controlled electric motors. The applied computer engine controls can be realized from case to case by other engine controls.
