The pins stored in the side wall 6 each have a spur gear 8 to 11 with which the cylinders 1.1, 1.2, 2.1, 2.2 with the adjacent cylinder in drive connection stand. Thus, the electric motor 7 (following in Fig. 1 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, the printing unit shown in Fig. 1 is about 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, whereby, not shown, the drive-side pins also Wear spur gears and the spur gear of the transfer cylinder 2.3 is in engagement with the spur gear 11 of the transfer cylinder 2.2.

Über diese Stirnräder 8 bis 11 stehen also alle Zylinder mit dem Formzylinder 1.1 in Antriebsverbindung und werden vom Elektromotor 7 angetrieben.About these spur gears 8 to 11 are all cylinders with the Forme cylinder 1.1 in drive connection and are from the electric motor 7 driven.

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 cooperating printing units 13, 14 with the forme cylinders 1.4, 1.5 and the transfer cylinders 2.4, 2.5 were added. Not each pin on the drive side of cylinders 1.4 is shown, 1.5, 2.4, 2.5 a spur gear, with which the cylinders in one another Stand by. Furthermore, the spur gear 11 of the Transfer cylinder 2.2. via a 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.4 is still one more than in FIG Satellite cylinder 16 added.

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.In the following figures 6 to 20 are recurring spatial arrangements of cylinders and printing units from the Figures 1 to 5 described for the sake of simplicity Item numbers reused, regardless of any structural Differences. Figures 6, 7 and 10 show bridges, i. H. parts of printing units which correspond to those shown in FIGS. 1, 2 and 5 described printing units match and therefore not are explained again in more detail.

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, the chain of wheels 15 has been eliminated compared to FIG. 3. The resulting lower printing unit bridge (double printing unit) with the Forme cylinders 1.1 and 1.2 and the transfer cylinders 2.1 and 2.2 is driven in the same way as in Figures 6 and 7. The resulting upper printing unit bridge with the form cylinders 1.4, 1.5 and the transfer cylinders 2.4, 2.5 is controlled by an angle Electric motor 7 driven, which engages the forme cylinder 1.4. The latter drives on the pin via spur gears, not shown the cylinder 1.4, 2.4, 2.5, 1.5 on 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.In Fig. 9 the situation is similar to Fig. 8. It will only from the forme cylinder 1.1 a satellite cylinder 16 by means of Gear chain 18 driven. Same or different types Printing unit bridges of Figures 6 to 9 can be different Printing units can be combined. You can also use the following drive cases described above are used.

Bei den bisher beschriebenen Ausführungsbeispielen kann auch jeder andere Form-, Übertragungs- oder der Satellitenzylinder vom Elektromotor angetrieben werden.In the exemplary embodiments described so far, anyone can other form, transmission or satellite cylinders from Electric motor are driven.

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. The double printing unit shown in FIG. 11 contains the printing units 3, 4 each with a forme cylinder 1.1, 1.2 and one Transfer cylinder 2.1, 2.2. These cylinders are equally in Side walls 5, 6 mounted (Fig. 15), as in Figures 1 and 6. However, each printing unit 3, 4 has its own angle-controlled electric motor 7, namely each the forme cylinder 1.1 or 1.2 driven. The drive side Pins of the forme cylinders 1.1, 1.2 each have a spur gear 8, 19, with which they each have a spur gear 10, 20 on the pin of Comb the transfer cylinders 2.1, 2.2. The spur gears 8, 10 and 19, 20 are in two different levels because the transfer cylinder 2.1, 2.2 must not be in drive connection with each other. On the operator-side pin of the forme cylinder 1.1, 1.2 engages in each case an angle-controlled electric motor 7 and drives the printing units 3, 4 on.

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 following embodiments the electric motors each on the forme cylinders. Instead it is also possible to drive the transfer cylinder. As such Example drive in the printing unit according to FIG Electric motors 7 each the transfer cylinder 2.1, 2.2, 2.3 of the Printing units 3, 4, 12. These are then made using spur gears the drive of the associated forme cylinder 1.1, 1.2, 1.3. Analogous to Fig. 15, the spur gears of the printing unit 4 and Printing unit 3 are not in one plane, nor are they Spur gears of printing units 4 and 12.

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.13, the forme cylinders 1.1, 1.2, 1.4, 1.5 of the printing units 3, 4, 13, 14 of one each angle-controlled electric motor 7 driven. Of these, by means of. Spur gears of the associated transfer cylinders 2.1, 2.2, 2.4, 2.5 driven. The spur gear drives working together Printing units are each on two different levels.

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.Analogously to FIG. 13, the printing units 3 are driven in FIG. 14, 4, 13, 14. In addition, the satellite cylinder 16 is one separate, angle-controlled electric motor 7 driven.

Bei den nicht beanspruchten 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 FIGS. 16 to 19, which are not claimed, each Forme cylinders 1.1 to 1.5 and each transfer cylinder 2.1 to 2.5 and, if available, the satellite cylinder 16 of one each separate, angle-controlled electric motor 7 driven. Warehousing the cylinder takes place in the same way as in the previous exemplary embodiments the side walls 5, 6. Deviating from the previous ones However, the electric motors 7 are each exemplary embodiments Pins of the so-called drive side S 2 arranged (Fig. 20). Likewise, the electric motors could also be on the operator-side pins to be appropriate. Also in the previous ones Embodiments of the electric motors 7 on the drive side Be attached. When equipping everyone Printing unit with its own drive motor (Fig. 11 to 14) can the individual printing units work well together are driven in a coordinated manner. With each drive separately Cylinder (Figures 16 to 19) is the unwinding drive even between the form and transfer cylinders 1, 2 of a printing unit possible. In addition, all gear drives and the otherwise necessary lubrication, gearbox encapsulation etc., resulting in huge cost savings. In addition, there is no need for desired printing unit controls mechanical (and electrical) devices as a result of this Reversal of the direction of rotation of the driving motors is accomplished.

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 exemplary embodiments, a printing unit always contains a form and a transfer cylinder and works with one Printing mechanism based on the rubber-rubber principle or with a satellite cylinder together. Such a printing unit can also be used with a Impression cylinders are added to a three-cylinder printing unit, each cylinder powered by a separate electric motor or only one cylinder is driven by an electric motor and the three cylinders are in drive connection via gearwheels.

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 angle control of the electric motors is carried out by means of Computer engine controls as part of machine control. The motors are accordingly connected to these systems. The Regulations are not the subject of the invention, so that Representations and explanations are not provided.

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, others can also be advantageously used Drive functional groups of printing machines. 21 is one Printing machine in side view and in Fig. 22 a folding unit shown in the view with such functional groups. The 21 includes four printing units 21 to 24 and a folding unit 25. The printing units 23 and 24 are similar driving the printing unit shown in Fig. 17, the Printing units 21 and 22 are similar to that shown in Fig. 18. The Drive motors of the cylinders as well as the one below Function groups described are symbolic with an "M" or Hatching. The folding unit shown in Fig. 22 contains the folding units 26 and 27. In FIG. 21 are the feed units 28, the cooling rollers 29, the cutting rollers 30 and the hopper rollers 31 of a separate, angle-controlled electric motor 33.1 to 33.5 driven. The electric motors overdrive indirectly Belt the cylinders of these functional groups. Fig. 21.1 shows the same printing press, with 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.22, the hopper rollers 31 and the tension and Transfer rollers 32 each of a separate, angle-controlled Electric motor driven directly. Also the two folding units 26 and 27 each have a separate, angle-controlled motor, the one folding cylinder each, here the knife cylinder 143, 144, directly drives. The other folding cylinders protrude with this cylinder spur gears arranged on their journals.

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.22.1, the former rolls 31 and the pull and transfer rollers 32 each have a common motor indirectly driven by a toothed belt. The only one Folding unit 27.1 is controlled by a separate, angle-controlled Electric motor driven. The drive takes place indirectly by means of Belt drive on the puncture folding knife cylinder, for example 145. With this the other folding cylinders stand with theirs Cylinder wheels in drive connection. With these electric motors a sensitive adjustment of the speed of the driven cylinders possible. For groups with advance control is also then the web tension can be adjusted accordingly. Surrender too great cost advantages from the elimination of such PIV gearboxes previously used.

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 separate electric motor driving directly onto a forme cylinder is also advantageous as an actuator for color register adjustment available. 23 shows a device for color register adjustment in a double printing unit with the printing units 34 and 35, each a forme cylinder 36, 38 and a transfer cylinder 37, 39 contain. The device is based on the forme cylinder 38 described, which carries two printing forms on the circumference. The the Form cylinder 38 driving electric motor 40 is powered by a Computer engine control 41 angle-controlled. Furthermore, a Position transmitter 42 of the printing unit 35 and the register marks of the web 43 leaving the printing unit 35 scanning the transducer 44 connected to a comparison device 45, the output of which the input of the computer engine control 41 is performed. The Transducer 44 scans from printing unit 35 onto web 43 printed register marks and thus determines the position of the two images printed per revolution of the forme cylinder. With the signal of the position transmitter 42 is in the Comparison device 45 the reference to the rotation of the forme cylinder 38 manufactured. With a staggered arrangement of a print image in Circumferential direction to half the circumference of the forme cylinder, d. H. at a arrangement of the printed image deviating from half the circumference, the Forme cylinder 38 before printing in this area with a balancing pre or post retracement. This is done using the Computer engine control according to the output signal of the Comparator 45 accomplished. With this you can for example copying errors or assembly errors of the printing form be balanced. Accepting certain cuts to the Registration quality at the start of printing can be the acceleration or Delay phase can also be extended into this area, whereby the electric motor is dimensioned with lower power can be.

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.The device shown in Fig. 24 is used to control the Circumferential register between two printing points, here between the printing unit 46 and 47. The from these printing units 46, 47 on the web 48 Printed registration marks are scanned by sensors 49, 50. The signals from the sensors 49, 50 are in the Comparator 51 passed. This gives the comparison result to the computer engine control 52. This controls the speed of the Forme cylinder 53 of the printing unit 47 driving electric motor 54. Each after necessary change of register to the printed image of the printing unit 46 the electric motor 54 is operated with advance or lag. If also the transfer cylinder 55 from a separate electric motor is driven, this is also with a register correction advantageously corrected for its speed. The device is according to the number of registers to be checked to be used accordingly in many ways or in a correspondingly fully expanded manner With the device, the traditional can be expensive mechanical gear z. B. sliding wheels Circumferential register adjustment of the forme cylinders 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 individual drive of the printing units, different ones can also be used Paper paths between different printing units without that Requires additional length adjustment facilities be driven. In the printing machine shown in Fig. 21 for example, web 55 can either be from printing unit 23 to Printing unit 21 or on the path shown in dashed lines to Printing unit 22 are performed. According to the different The printing units of the printing units 21 and 22 are removed by means of their Drive motors moved into the required position. This is the computer motor control 56 of the electric motors on the input side a computing and storage unit 57 in which the required cylinder positions are stored. These will depending on the web run the computer engine control 56, which the Form and transfer cylinders by controlling their Electric motors moves into 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 computing and storage unit 57 contains possible web runs the cylinder positions of the printing units for the Cutting register saved. For cutting register setting according to the selected production configuration of the Computer engine control 56 the required cylinder positions specified. Adjusted according to the specification Computer engine control 56 drives all of the web 55 printing units. The cutting register for cutting in the folder is therefore about the cylinder positions of everyone involved in printing Printing units set. The usual, costly linear register devices. Only for that Such a length adjustment is still necessary for the turning strand. The one containing the cylinder positions for the cutting register The computing and storage unit can also be used for computer engine control 66 of the device shown in FIG. 25, described below be guided, this device then both the Cutting register regulation as well as adjustment serves.

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 also under Elimination of previously common connecting elements, such as synchronous shafts, Couplings, gears and positioning devices, Printing press associations can be put together variably. About one corresponding control program can, for.
