Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum registergerechten Positionieren von Druckformhülsen nach dem Oberbegriff von Anspruch 1 und 12.The invention relates to a method and a device for register-correct positioning of printing form sleeves according to the preamble of claims 1 and 12.

Bekannt ist es (DE 41 40 768 A1), mit Hilfe von formschlüssigen oder optischen Registereinrichtungen - beispielsweise in Aussparungen der Druckformhülse registerhaltig eingreifende Registerstifte des Druckformzylinders bzw. in Übereinstimmung zu bringende Markierungen auf Druckformhülse und Druckformzylinder - die Registerhaltigkeit der durch ein Druckgaspolster gegenüber dem Druckzylinder eine Verschiebung ermöglichend freisetzbaren Druckformhülse herzustellen.It is known (DE 41 40 768 A1), with the aid of interlocking or optical register devices - for example register pins of the printing form cylinder engaging in register-like recesses in the printing form sleeve or markings to be brought into conformity on the printing form sleeve and printing form cylinder - the register accuracy of the pressure gas cushion relative to the printing cylinder to produce a shift enabling releasable printing form sleeve.

Das registergerechte Ausrichten mehrerer Druckformhülsen beim jeweiligen Aufstecken auf die Druckzylinder ist relativ kompliziert und erfordert viel Sorgfalt durch das Bedienungspersonal.The correct alignment of several printing form sleeves when they are each attached to the printing cylinder is relatively complicated and requires a great deal of care by the operating personnel.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum registergerechten Positionieren von Druckformhülsen gemäß Oberanspruch 1 und 12 zu schaffen, die ohne besondere Anforderungen an das Bedienungspersonal eine schnelle Registerhaltigkeit insbesondere mehrerer auf verschiedene Druckzylinder aufgesteckter Druckformhülsen gewährleisten.The invention has for its object to provide a method and an apparatus for register-correct positioning of printing form sleeves according to claims 1 and 12, which ensure fast register stability, in particular several printing form sleeves plugged onto different printing cylinders, without special requirements for the operating personnel.

Die Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 verfahrensgemäß und von Anspruch 12 vorrichtungsgemäß gelöst.The object is achieved by the characterizing features of claim 1 according to the method and by claim 12 according to the device.

Durch das Aufstecken der Druckformhülse auf den Druckzylinder in beliebiger Lage ohne auf die Registerhaltigkeit gerichtete Sorgfaltpflicht des Bedienungspersonals ist dieser Vorgang in kurzer Zeit realisierbar.By pushing the printing form sleeve onto the printing cylinder in any position without the operator having to exercise due diligence, this process can be carried out in a short time.

Die nachfolgende von menschlichen Einflüssen freie automatische Einstellung der registergerechten Positionen der Druckformhülsen ermöglicht - auch unter Berücksichtigung von den Druckvorgang beeinflussenden Einflußfaktoren - eine exakte Registerhaltigkeit in kurzer Zeit. Beispielsweise werden für die Meßfahrt zur Bestimmung der Positionen der aufgesteckten Druckformhülsen und deren anschließenden registergerechten Positionierung nur zwei Antriebsumdrehungen benötigt.The subsequent automatic adjustment of the register-correct positions of the printing form sleeves, free from human influences, enables - also taking into account the influencing factors influencing the printing process - an exact registration in a short time. For example, only two drive revolutions are required for the measurement run to determine the positions of the attached printing form sleeves and their subsequent correct positioning.

Die Unteransprüche enthalten weitere vorteilhafte Ausgestaltungen der Erfindung.The subclaims contain further advantageous refinements of the invention.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert. Die zugehörige Zeichnung zeigt:The invention is explained in more detail below using an exemplary embodiment. The accompanying drawing shows:

eine Vorrichtung zum registergerechten Positionieren von mehreren Druckformhülsen auf den Druckzylindern verschiedener Druckwerke einer Rotationsdruckmaschine.a device for registering correct positioning of several printing form sleeves on the printing cylinders of different printing units of a rotary printing press.

Zwei sowohl für einen direkten als auch indirekten Druck konzipierbare Druckwerke 1; 2 sind jeweils mit einem eine Druckformhülse 3; 4 tragenden Druckzylinder 5; 6 ausgestattet.Two printing units 1; which can be designed for both direct and indirect printing; 2 are each with a printing form sleeve 3; 4 supporting pressure cylinder 5; 6 equipped.

Die elastisch aufweitbaren Druckformhülsen 3; 4 werden stirnseitig auf die Druckzylinder 5; 6 mittels eines auf deren Umfang erzeugbaren Druckgaspolsters aufgeschoben und nach dem Erreichen eines vorzugsweise pneumatisch aus dem jeweiligen Druckzylinder 3; 4 auf der gegenüberliegenden Seite ausfahrbaren Paßanschlages mit dem Abschalten des Druckgaspolsters durch Reibschluß auf dem Druckzylinder festgesetzt.The elastically expandable printing form sleeves 3; 4 are on the end of the pressure cylinder 5; 6 pushed on by means of a pressure gas cushion that can be generated on its circumference and after reaching a preferably pneumatic one from the respective pressure cylinder 3; 4 on the opposite side extendable fitting stop with the shutdown of the gas cushion by friction on the pressure cylinder.

Das Druckgas wird jeweils durch bekannte, nicht dargestellte, u. a. auch Wegeventile umfassende Versorgungseinrichtungen zugeführt und durch eine Axialbohrung 7; 8 des Zapfens 9; 10 in den Druckzylinder 5; 6 eingeleitet, aus dem es über Umfangsöffnungen austritt.The compressed gas is in each case by known, not shown, u. a. also supplied directional valves comprehensive supply devices and through an axial bore 7; 8 of the pin 9; 10 in the impression cylinder 5; 6 initiated, from which it exits via circumferential openings.

Die Druckformhülsen 3; 4 besitzen jeweils eine, beispielsweise als optisch registrierbare Paßmarke ausgeführte Positionsmarkierung 11; 12, die für einen gestellfesten Sensor 13; 14 erkennbar ist.The printing form sleeves 3; 4 each have a position marker 11, for example in the form of an optically registerable registration mark; 12, which is for a frame-fixed sensor 13; 14 is recognizable.

Ebenfalls jeweils im Bereich der aufgesteckten Druckformhülse 3; 4 befindet sich eine mit einem auf letztere aufsetzbaren Sauger 15; 16 ausgestattete pneumatische Haltevorrichtung 17; 18.Also in the area of the attached printing form sleeve 3; 4 is one with a suction cup 15 that can be placed on the latter; 16 equipped pneumatic holding device 17; 18th

Sowohl die Haltevorrichtungen 17; 18 als auch die Sensoren 13; 14 können für eine bessere Zugänglichkeit beim Wechsel der Druckformhülsen 3; 4 abschwenk- bzw. verstellbar am Gestell befestigt sein.Both the holding devices 17; 18 and the sensors 13; 14 can for better access when changing the printing form sleeves 3; 4 swivel or adjustable attached to the frame.

Die Druckzylinder 5; 6 werden von einem Antrieb 19 über eine gemeinsame Antriebswelle 20 angetrieben, mit der ein Incrementalgeber 21 verbunden ist, der aus einer auf der Antriebswelle 20 sitzenden, mit optischen Markierungen versehenen Teilscheibe 22 und einem gestellfesten opto-elektrischen Sensor 23 besteht.The pressure cylinder 5; 6 are shared by a drive 19 Drive shaft 20 driven, to which an incremental encoder 21 is connected, which consists of a partial disk 22, which is seated on the drive shaft 20 and provided with optical markings, and an opto-electrical sensor 23 fixed to the frame.

Sowohl die Impulse I des Incrementalgebers 21 als auch die von den Positionsmarkierungen 11; 12 der Druckformhülsen 3; 4 verursachten Impulse IM; IM' der Sensoren 13; 14 werden einem Rechner 24 zugeleitet, der mit einer Steuereinheit 25 gekoppelt ist, die den Antrieb 19 steuert, die Haltevorrichtungen 17; 18 in Funktion setzt sowie die Betätigung einer mit dem Antrieb 19 verbundenen und einer jeweils auf den Zapfen 9; 10 der Druckzylinder sitzenden Bremse 26; 27; 28 bewirkt.Both the pulses I of the incremental encoder 21 and those of the position markers 11; 12 of the printing form sleeves 3; 4 caused pulses I M ; I M 'of the sensors 13; 14 are fed to a computer 24 which is coupled to a control unit 25 which controls the drive 19, the holding devices 17; 18 sets in function and the actuation of one connected to the drive 19 and one each on the pin 9; 10 of the pressure cylinder seated brake 26; 27; 28 causes.

Nach der Bestückung der Druckzylinder 5; 6 mit den Druckformhülsen 3; 4 erfolgt durch den Antrieb 19 eine Meßfahrt von einer Umdrehung im Schleichgang zur Ermittlung der Positionen der in beliebiger Lage aufgesteckten Druckformhülsen 3; 4. Aus den Impulsen IM; IM' der Sensoren 13; 14 und den Impulsen Iρ des Incrementalgebers 21 ermittelt der Rechner die jeweilige Winkelabweichung α ; α' der Druckformhülsen 3; 4, die in einer nachfolgenden zweiten Antriebsumdrehung mit der kleinsten Winkelabweichung α' beginnend und mit zunehmender Größe bei der größten Winkelabweichung α endend in Folge korrigiert werden, indem jeweils der Sauger 16 bzw. 15 der Haltevorrichtungen 18 bzw. 17 auf die Druckformhülse 4 bzw. 3 diese fixierend aufsetzt. Letztere wird durch die Erzeugung des Druckgaspolsters vom Druckzylinder 6 bzw. 5 gelöst, der darauf um die Winkelabweichung α' bzw. α verdreht wird. Nach dem Abschalten des Druckgaspolsters setzt sich die Druckformhülse 4 bzw. 3 in der registergerechten Position auf dem Druckzylinder 6 bzw. 5 fest und wird von der Haltevorrichtung 18 bzw. 17 wieder freigegeben.After the printing cylinder 5; 6 with the printing form sleeves 3; 4, a drive of one revolution in creep speed takes place by the drive 19 to determine the positions of the printing form sleeves 3; 4. From the pulses I M ; I M 'of the sensors 13; 14 and the pulses Iρ of the incremental encoder 21, the computer determines the respective angular deviation α; α 'of the printing form sleeves 3; 4, which are corrected in a subsequent second drive revolution with the smallest angular deviation α ′ and ending with increasing size with the largest angular deviation α in succession, in each case by the suction device 16 or 15 of the holding devices 18 or 17 on the printing form sleeve 4 or 3 fixes them. The latter is released by the production of the pressure gas cushion from the pressure cylinder 6 or 5, which is then rotated by the angular deviation α 'or α. After the pressure gas cushion has been switched off, the printing form sleeve 4 or 3 settles in the register-correct position on the pressure cylinder 6 or 5 and is released again by the holding device 18 or 17.

Zur Vermeidung von Antriebsspiel sind sowohl bei der Meßfahrt als auch beim Verstellen des Registers die Bremsen 26; 27; 28 angebremst, d. h. mit reduzierter Bremskraft im Einsatz.To avoid drive play, the brakes 26 are both during the measurement run and when adjusting the register; 27; 28 braked, d. H. with reduced braking force in use.

Da sich die Bahnlängen zwischen den Druckwerken 1; 2 in Abhängigkeit der Produktionsvarianten ändern, werden diese berücksichtigende Korrekturwerte KP in den Rechner eingegeben.Since the web lengths between the printing units 1; 2 change depending on the production variants, these correcting correction values K P are entered into the computer.

Gleiches ist auch für die Bahnlängen beeinflussende Verarbeitungsgrößen, wie z. B. Dehnung oder Schrumpfung der Warenbahn, Ablöseverhalten vom Übertragungszylindern, zutreffend, die ebenfalls als Korrekturwerte KV in den Rechner eingegeben werden. Diese Korrekturwerte KP; KV sowie der bei der Meßfahrt mit ermittelte Nachlauf des Antriebes werden vom Rechner 24 zusätzlich in die jeweils zu korrigierende Winkelabweichung α ; α' eingerechnet.The same is also true for processing quantities influencing the web lengths, such as, for. B. stretch or shrinkage of the web, separation behavior from the transfer cylinders, applicable, which are also entered as correction values K V in the computer. These correction values K P ; K V and the run-on of the drive determined during the measurement run are additionally calculated by the computer 24 into the angular deviation α; Including α '.

In Abhängigkeit davon, ob es sich bei den Druckwerken 1; 2 um einen indirekten oder direkten Druck handelt, kann der mit dem als Formzylinder fungierenden Druckzylinder 5; 6, zusammenarbeitende mittlere Zylinder 29; 30 ein Übertragungszylinder oder ein Gegendruckzylinder und der nachfolgende äußere Zylinder 31; 32 ein Gegendruckzylinder oder ein weiterer Formzylinder sein.Depending on whether it is in the printing units 1; 2 is an indirect or direct printing, the printing cylinder 5; 6, cooperating middle cylinder 29; 30 a transfer cylinder or an impression cylinder and the subsequent outer cylinder 31; 32 be an impression cylinder or another forme cylinder.

Um sicherzustellen, daß der Verstellbereich von nicht dargestellten Registereinrichtungen für den Fortdruck, wie z. B. Registerwalzen oder Verstellgetriebe für die Druckzylinder 5; 6, nach der registergerechten Positionierung der Druckformhülsen 3; 4 auf den Druckzylindern 5; 6, noch ausreicht, ist es zweckmäßig, diese Registereinrichtungen vor der Bestückung der Druckzylinder 5; 6 mit Druckformhülsen 3; 4 auf die Mitte ihres Verstellbereiches einzustellen ohne ihre von der Mitte ihres Verstellbereiches abweichenden Stellungen bei der Bestückung der Druckzylinder 5; 6 mit Druckformhülsen 3; 4 gesondert zu erfassen und entsprechend bei der Korrektur aller Winkelabweichungen α ; α' zusätzlich zu berücksichtigen, wozu insbesondere im letzteren Fall dem Rechner die dafür erforderlichen Informationen zugeleitet werden müssen.To ensure that the adjustment range of register devices, not shown, for production, such as. B. register rollers or adjusting gear for the pressure cylinder 5; 6, after the registration-correct positioning of the printing form sleeves 3; 4 on the printing cylinders 5; 6, is still sufficient, it is useful to register these register devices before loading the printing cylinder 5; 6 with printing form sleeves 3; 4 to be set to the center of their adjustment range without their positions deviating from the center of their adjustment range when loading the pressure cylinders 5; 6 with printing form sleeves 3; 4 to be recorded separately and accordingly in the correction of all angular deviations α; α 'must also be taken into account, for which purpose the information required for this must be supplied to the computer, in particular in the latter case.
