Die Erfindung betrifft eine Anordnung zum Verhindern von Druckwerksschäden an Rollenrotationsdruckmaschinen entsprechend dem Oberbegriff des Anspruches 1.The invention relates to an arrangement for prevention of printing unit damage to web-fed rotary printing presses according to the preamble of claim 1.

Bekannterweise kommt es beim Ausfall der elektrischen Versorgung auch zum Ausfall der elektrisch betriebenen Aggregate, was zu Unregelmäßigkeiten in der mechanischen Spannung der laufenden Papierbahn in Rollenrotationsdruckmaschinen führen kann, so daß ein sog. Bruch der Papierbahn entstehen kann, bevor die Druckmaschine zum Stillstand kommt. Dies kann zu sogenannten Wicklern führen, welche die Druckwerke oder auch die Farbwerke beschädigen können.As is known, it happens when the electrical fails Supply also for the failure of the electrically operated Aggregates, leading to irregularities in the mechanical tension of the running paper web in Rotary printing presses can lead, so that a So-called breakage of the paper web can arise before the Printing machine comes to a standstill. This can be too so-called winder, which the printing units or can also damage the inking units.

Die DE 36 29 719 A1 beschreibt eine Anordnung zum Verhindern von Druckwerksschäden an einer Druckmaschine. Dabei ist einem Drehwinkelmotor ein Hydrospeicher zugeordnet, um einen Zylinder in eine Druckabstellung zu bringen.DE 36 29 719 A1 describes an arrangement for Preventing printing unit damage to a printing press. A rotary motor is a hydraulic accumulator assigned to a cylinder in a print stop too bring.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1 solved.

Durch die Erfindung treten insbesondere folgende Vorteile ein:
Infolge der Anordnung eines Energiespeichers, der im Falle des Ausfalls der elektrischen Versorgung kurzzeitig Energie zum Betätigen einer Steuereinheit abgibt, die wiederum ein Verschwenken zumindest eines Gummituchzylinders je in Betrieb befindlicher Druckeinheit bewirkt, sind Wickler beim Reißen der Papierbahn unschädlich geworden.
The invention has the following advantages in particular:
As a result of the arrangement of an energy store which, in the event of a failure of the electrical supply, briefly releases energy for actuating a control unit, which in turn causes at least one blanket cylinder to pivot for each printing unit in operation, winders have become harmless when the paper web is torn.

The invention is illustrated in more detail below using an exemplary embodiment. The associated drawings show in
Fig. 1
a schematic diagram of an arrangement according to the invention;
Fig. 2
the schematic representation of a satellite printing unit.

Um einen zentralen Gegendruckzylinder 1 sind kreuzförmig vier aus jeweils einem Gummituchzylinder 2, 3, 4, 5 und einem Plattenzylinder 7, 8, 9, 10 bestehende Druckeinheiten 2, 7; 3, 8; 4, 9; 5, 10 zu einer sogenannten Neunzylinder-Satellitendruckeinheit 12 für eine Rollenrotationsdruckmaschine angeordnet. Die Druckeinheiten 2, 7; 3, 8; 4, 9; 5, 10 sind so umschaltbar, daß eine oder mehrere Papierbahnen 13, 14 die Satellitendruckeinheit 12 zwecks Bedrucken der Papierbahn 13, 14 durchlaufen können (Fig. 2). Dabei können z. B. die Gummituchzylinder 2 und 3 sowie die Gummituchzylinder 4 und 5 Kontakt haben oder alle Gummituchzylinder 2 bis 5 arbeiten z. B. gegen den Gegendruckzylinder 1. Die Plattenzylinder 7 bis 10 sind den Gummituchzylindern 2 bis 5 jeweils separat zugeordnet. Den Plattenzylindern 7 bis 10 jeweils zugeordnete Farbwerke und ggf. auch Feuchtwerke sind nicht dargestellt. Die Gummituchzylinder 2 bis 5 können, wie in der DE 41 29 840 A1 gezeigt, jeweils separat mittels doppeltwirkender Arbeitszylinder 16 verschwenkbar im Seitengestell angeordnet sein, wobei die Gummituchzylinder 2 bis 5 jeweils zumindest drei verschiedene Stellungen einnehmen können:

  • a) Gummituchzylinder 2 gegen benachbarten Gummituchzylinder 3, Markierung 39 an einer Exzenterbüchse 18 in "Druckanstellung D",
  • b) Gummituchzylinder 4 gegen benachbarten Gummituchzylinder 5, Markierung 39 der Exzenterbüchse 18 in "Druckanstellung D",
  • c) Gummituchzylinder 2 bis 5 gemeinsam gegen Gegendruckzylinder 1, Markierung 39 der Exzenterbüchse 18 in Druckanstellung B",
  • d) Gummituchzylinder 2 bis 5 in Druckabstellung, d. h. ohne Kontakt zu benachbarten Zylindern, Markierung 39 der Exzenterbüchse 18 in "Druckabstellung C".
  • Around a central impression cylinder 1, four printing units 2, 7; each consisting of a blanket cylinder 2, 3, 4, 5 and a plate cylinder 7, 8, 9, 10; 3, 8; 4, 9; 5, 10 to a so-called nine-cylinder satellite printing unit 12 for a web-fed rotary printing press. The printing units 2, 7; 3, 8; 4, 9; 5, 10 can be switched so that one or more paper webs 13, 14 can pass through the satellite printing unit 12 for printing on the paper web 13, 14 (FIG. 2). Here, for. B. the blanket cylinders 2 and 3 and the blanket cylinders 4 and 5 have contact or all blanket cylinders 2 to 5 work z. B. against the impression cylinder 1. The plate cylinders 7 to 10 are each assigned to the blanket cylinders 2 to 5 separately. The inking units assigned to the plate cylinders 7 to 10 and possibly also dampening units are not shown. As shown in DE 41 29 840 A1, the rubber blanket cylinders 2 to 5 can each be separately pivoted in the side frame by means of double-acting working cylinders 16, the rubber blanket cylinders 2 to 5 each being able to assume at least three different positions:
  • a) blanket cylinder 2 against adjacent blanket cylinder 3, marking 39 on an eccentric bush 18 in "printing position D",
  • b) blanket cylinder 4 against adjacent blanket cylinder 5, marking 39 of the eccentric bush 18 in "printing position D",
  • c) blanket cylinders 2 to 5 together against impression cylinder 1, marking 39 of the eccentric bushing 18 in the printing position B ",
  • d) rubber blanket cylinders 2 to 5 in the printing position, ie without contact with adjacent cylinders, marking 39 of the eccentric bushing 18 in "printing position C".
  • Das Verschwenken der Gummituchzylinder 2 bis 5 geschieht beispielsweise dadurch, daß jeder Achszapfen 17 eines jeden Gummituchzylinder 2 bis 5 jeweils in einer im Seitengestell 22 drehbar angeordneten Exzenterbüchse 18 gelagert ist, wobei jede Exzenterbüchse 18 an einem exzenterbüchsenfesten Flansch 19 mittels einer Koppel 21 sowie einem seitengestellfest gelagertem Winkelhebel 23 mit dem kolbenfernen Ende einer Kolbenstange 24 des Arbeitszylinders 16 verbunden ist. Der Arbeitszylinder 16 ist an seinem kolbenstangenfernen Ende seitengestellfest gelagert. Die Teile 16 bis 19 und 21 bis 24 sind zweifach vorhanden und sind - außer dem Seitengestell 22 - als Stellmittel 26 bezeichnet. Der doppeltwirkende Arbeitszylinder 16 der Stellmittel 26 ist jeweils an seinen Enden über jeweils eine Leitung 27, 28 mit jeweils einem Drosselventil mit nicht näher bezeichneten Arbeitsanschlüssen eines 4/3-Wegeventils 29 mit magnetischer Betätigung 31, 32 verbunden. Das Wegeventil 29 weist in seiner Mittelstellung eine Sperrstellung auf. Eine Zu- und Rückleitung 33, 34 des Wegeventils 29 ist mit einem bekannten Druckluftspeicher 35 mit Anschluß 40 zu einer bekannten Erzeugeranlage verbunden. Die erste Magnetbetätigung 31 des Wegeventils 29 ist mit Öffnern 36, 37 eines ersten Endschalters 38 in Verbindung, welcher seitengestellfest in der Nähe des Achszapfens 17 jedes Gummituchzylinders 2 bis 5 angebracht ist und dessen Kontaktbetätigungshebel mit einem exzenterbüchsenfesten Nocken 58 in kraftschlüssiger Verbindung ist. Schließer 41, 42 in einem zweiten Endschalter 43 sind ebenfalls seitengestellfest in der Nähe des Achszapfens 17, jedoch an einer anderen Stelle des Umfanges der Exzenterbüchse 18 angeordnet. Der Kontaktbetätigungshebel des Endschalters 43 ist je nach Lage der Gummituchzylinder mit der Oberfläche der Zylinderbüchse 18 oder mit einem zylinderbüchsenfesten Nocken 59 in kraftschlüssiger Verbindung. Sowohl der Öffner 36 des ersten Endschalters 38 als auch der Schließer 41 des zweiten Endschalters 43 steht mit einem ersten Anschluß eines Öffners 44 eines Relais 46 in Verbindung. Die Teile 29, 31, 32, 38, 43, 46 sind als Steuermittel 47 bezeichnet.The blanket cylinders 2 to 5 are pivoted for example, in that each journal 17 one each blanket cylinder 2 to 5 each in one Side frame 22 rotatably arranged eccentric bush 18 is mounted, with each eccentric bushing 18 an eccentric bush fixed flange 19 by means of a Coupling 21 and a side frame fixed Angle lever 23 with the end remote from the piston Piston rod 24 of the working cylinder 16 is connected. The working cylinder 16 is on its piston rod remote End fixed on the side frame. Parts 16 to 19 and 21 to 24 are duplicate and are - besides that Side frame 22 - referred to as adjusting means 26. Of the double-acting working cylinder 16 of the adjusting means 26 is at its ends via a line 27, 28 each with a throttle valve with no closer designated working connections of a 4/3-way valve 29 connected with magnetic actuation 31, 32. The Directional control valve 29 has one in its central position Lock position on. A supply and return line 33, 34 of the Directional control valve 29 is with a known compressed air reservoir 35 with connection 40 to a known generating plant connected. The first solenoid actuator 31 of the directional valve 29 is with break contacts 36, 37 of a first limit switch 38 in connection, which is fixed to the side frame in the Near the journal 17 of each blanket cylinder 2 to 5 is attached and its contact operating lever with an eccentric bush fixed cam 58 in non-positive connection. NO 41, 42 in a second limit switch 43 are also fixed on the side frame near the axle journal 17, however at another point on the circumference of the eccentric sleeve 18 arranged. The contact operating lever of the Limit switch 43 is depending on the location of the blanket cylinder with the surface of the cylinder liner 18 or with a cylinder liner-fixed cams 59 in non-positive Connection. Both the opener 36 of the first limit switch 38 and also the closer 41 of the second limit switch 43 stands with a first connection of an opener 44 Relay 46 in connection. Parts 29, 31, 32, 38, 43, 46 are designated as control means 47.

    Ein Öffner 37 des Endschalters 38 sowie ein Schließer 42 des Endschalters 43 liegen einerseits an der Betriebsspannung UB, z. B. 24 Volt Gleichspannung, an und sind andererseits mit Eingängen E1, E2 einer speicherprogrammierbaren Steuerung 45 (SPS) verbunden. Ausgänge der SPS 45 sind über einen Stromrückfluß verhindernde Dioden 48, 49 parallel zu den Kontakten 36, 41 der beiden Endschalter 38, 43 geschaltet, um eine Schalterstellungsanzeige der Endschalter 38, 43 für den Fall der Wiedereinschaltung nach einem Ausfall der elektrischen Versorgung zu signalisieren.An opener 37 of the limit switch 38 and a closer 42 of the limit switch 43 are on the one hand on the Operating voltage UB, e.g. B. 24 volts DC, on and on the other hand are one with inputs E1, E2 programmable logic controller 45 (PLC) connected. Outputs of the PLC 45 are via a current return preventing diodes 48, 49 in parallel with the contacts 36, 41 of the two limit switches 38, 43 switched to a switch position indicator of the limit switches 38, 43 for the case of restart after a failure of the to signal electrical supply.

    Die Steuermittel 47 sind mit einem Elektroenergiespeicher 51 verbunden, welcher aus einem an Masse 53 UB - gelegten Kondensator 54 besteht, welchem eine Diode 52 vorgeschaltet ist. Der Diode 52 ist ein Widerstand 55 zwecks Strombegrenzung vorgeschaltet. Parallel zum Kondensator 54 kann ein Schutzwiderstand 61, z. B. von einem Kiloohm, angeordnet sein. Die Kapazität des Kondensators 54 kann 2 mal 10 Nanofarad bei 40 Volt betragen. Der der Diode 52 vorgeschaltete Widerstand 55 kann 1 Ohm betragen. Zwischen der Diode 52 und dem Kondensator 54 befindet sich ein Verteilerpunkt 56. Vom Verteilerpunkt 56 besteht eine Verbindung zum zweiten Anschluß des Öffners 44 des Relais 46, wodurch der Elektroenergiespeicher 51 mit dem Steuermitteln 47 verbindbar ist.The control means 47 are with a Electrical energy storage 51 connected, which consists of a capacitor 54 connected to ground 53 UB, which is preceded by a diode 52. The diode 52 is a resistor 55 for current limitation upstream. In parallel with the capacitor 54, a Protective resistor 61, e.g. B. of a kiloohm be. The capacitance of the capacitor 54 can be 2 times 10 nanofarads at 40 volts. That of the diode 52 upstream resistor 55 can be 1 ohm. Is located between the diode 52 and the capacitor 54 there is a distribution point 56. From distribution point 56 there is a connection to the second connection of the opener 44 of the relay 46, as a result of which the electrical energy store 51 can be connected to the control means 47.

    Die Funktionsweise der Anordnung ist wie folgt: Während des Betriebszustandes sind neben den nichtgezeigten Motorantrieben für die Druckmaschine auch die Gummituchzylinder 2 bis 5 der Satellitendruckeinheit 12 in Betrieb, und zwar so, daß die Gummituchzylinder 2 und 3 gegeneinander und die Gummituchzylinder 4 und 5 gegen den Gegendruckzylinder 1 arbeiten. Der gegen Masse 53 liegende Kondensator 54 wird während des Betriebes durch das Anliegen an der Betriebsspannung UB aufgeladen. Das zum Energiespeicher 51 parallel geschaltete Relais 46 hat während des Betriebes angezogen, so daß der Öffner 44 geöffnet ist. Somit haben die Steuermittel 47 nicht angesprochen.The arrangement works as follows: During the operating state, in addition to the Motor drives for the printing press, not shown, also the blanket cylinders 2 to 5 of the satellite printing unit 12 in operation, so that the blanket cylinder 2 and 3 against each other and the blanket cylinders 4 and 5 work against the impression cylinder 1. The against Ground 53 lying capacitor 54 is during the Operation by the concern of the operating voltage UB charged. That parallel to the energy storage 51 switched relay 46 has during operation tightened so that the opener 44 is open. Consequently have not addressed the control means 47.

    Bei Spannungsausfall, d. h. UB ist gleich Null, fällt das Relais 46 ab, der Öffner 44 schließt sich und die Energie des Kondensators 54 entlädt sich über den Öffner 36 des ersten Endschalters 38, so daß die Magnetbetätigung 31 des Wegeventils 29 zumindest über eine Sekunde lang vom Kondensator 54 Spannung erhält, so daß der Kolben 57 mit der Kolbenstange 24 des Arbeitszylinders 16 vom Druckluftspeicher 35 über das Wegeventil 29 und die Leitung 27 verbunden ist, so daß der Kolben 57 aus seiner linken Endstellung in Richtung rechte Endstellung bewegt wird, wodurch der Gummituchzylinder 2 bis 5 um einen Betrag d sowohl vom Gegendruckzylinder 1 als auch vom Plattenzylinder 7 bis 10 weggeschwenkt wird. Dadurch werden mögliche Papierwickler für das aus Gegendruckzylinder 1, Gummituchzylinder 2 bis 5 sowie Plattenzylinder 7 bis 10 bestehende Druckwerke unschädlich (siehe gestrichelte Darstellung der Gummituchzylinder 2 bis 5 in Fig. 2). Die Diode 52 verhindert dabei das Entladen des Kondensators 54 in Richtung Plus UB. Während der Bewegung des Kolbens 57 des Arbeitszylinders 16 von der linken Endstellung B zur mittleren Stellung C dreht sich gleichzeitig die Exzenterbüchse 18 im Uhrzeigersinn solange, bis der exzenterbüchsenfeste Nocken 58 den Kontaktbetätigungshebel des Endschalters 38 passiert hat und abschaltet, wobei der Öffner 36 öffnet. Dieser Vorgang dauert weniger als eine Sekunde, so daß die auf der Zylinderbüchse 18 befindliche Markierung 39 nunmehr mit einer auf dem Seitengestell 22 angebrachten Markierung C in Übereinstimmung ist. Somit nimmt der Gummituchzylinder 5 eine Druckabstellung ein (in Fig. 2 gestrichelt dargestellt).In the event of a power failure, i.e. H. UB is zero, falls the relay 46 off, the break contact 44 closes and the energy of the capacitor 54 is discharged the opener 36 of the first limit switch 38, so that the magnet actuation 31 of the directional control valve 29 at least over a second from capacitor 54 voltage receives so that the piston 57 with the piston rod 24 of the Working cylinder 16 from the compressed air reservoir 35 via the Directional control valve 29 and line 27 is connected so that the piston 57 from its left end position in the direction right end position is moved, whereby the Blanket cylinder 2 to 5 by an amount d both from Impression cylinder 1 and from plate cylinder 7 to 10 is pivoted away. This makes possible Paper winder for the impression cylinder 1, Blanket cylinders 2 to 5 and plate cylinders 7 to 10 existing printing units harmless (see dashed lines Illustration of the blanket cylinders 2 to 5 in Fig. 2). The diode 52 prevents the discharge of the Capacitor 54 towards Plus UB. During the Movement of the piston 57 of the working cylinder 16 from the left end position B to middle position C rotates at the same time the eccentric bush 18 clockwise until the cam which is fixed to the eccentric bushing 58 den Contact actuation lever of the limit switch 38 has passed and switches off, the opener 36 opens. This Operation takes less than a second, so the on the marking 39 of the cylinder liner 18 now with one attached to the side frame 22 Mark C is in agreement. Thus the A blanket cylinder 5 a print stop (in Fig. 2nd shown in dashed lines).

    Sollten sich jedoch die Gummituchzylinder 4, 5 während des Betriebes gegenseitig berühren, wie dies bei den Gummituchzylindern 2, 3 in Fig. 2 gezeigt ist, so befindet sich der Kolben 57 des Arbeitszylinders 16 in der rechten Endstellung D und die Markierung 39 auf der Exzenterbüchse 18 befindet sich in Übereinstimmung mit der auf dem Seitengestell 22 aufgebrachten Markierung D. Fällt dann die Betriebsspannung UB aus, so schließt der Öffner 44 des Relais 46, die Öffner 36, 37 des Endschalters 38 sind geöffnet und die Schließer 41, 42 des Endschalters 43 sind geschlossen. Der Kontaktbetätigungshebel des Endschalters 43 ist in Verbindung mit dem exzenterbüchsenfernen Nocken 59 bei Betätigung des Kolbens 57 des Arbeitszylinders 16 aus der rechten Arbeitsstellung D zur Druckabstellung C. Nachdem sich der im Gegenuhrzeigersinn drehende Nocken 59 am Kontaktbetätigungshebel des Endschalters 43 vorbeigefahren ist, schaltet der Endschalter 43 ab, so daß sich die Schließer 41, 42 öffnen und die Druckabstellung C des Gummituchzylinders 5 erreicht ist (gestrichelte Darstellung in Fig. 2), so daß Papierwickler vermieden werden.However, should the blanket cylinders 4, 5 during of the company touch each other, as is the case with the Blanket cylinders 2, 3 shown in Fig. 2, so is the piston 57 of the working cylinder 16 in the right end position D and the marking 39 the eccentric bush 18 is in agreement with that applied to the side frame 22 Mark D. If the operating voltage UB fails, the normally closed 44 of the relay 46 closes the normally closed 36, 37 of the limit switch 38 are open and the Normally open contacts 41, 42 of the limit switch 43 are closed. The contact operating lever of the limit switch 43 is in connection with cam 59 remote from the eccentric sleeve when the piston 57 of the working cylinder 16 is actuated from the right working position D to the print stop C. After the counterclockwise rotating Cam 59 on the contact operating lever of the limit switch 43 has passed, the limit switch 43 switches from, so that the closer 41, 42 open and the Print stop C of the blanket cylinder 5 reached is (dashed line in Fig. 2), so that Paper winder can be avoided.

    Es versteht sich von selbst, daß für jeden Gummituchzylinder 2 bis 5 eine separate Anordnung zum Verhindern von Druckwerksschäden erforderlich ist, wobei ja ohnehin schon ein Arbeitszylinder 57 zum Betätigen je Gummituchzylinder 2 bis 5 je Satellitendruckeinheit vorhanden sein muß, desgleichen Endschalter 38, 43. Somit können auch die Gummituchzylinder 2, 3 (Fig. 2) so verschwenkt werden, daß diese weder Kontakt zueinander besitzen, noch mit dem Plattenzylinder 7, 8 in Kontakt sind.It goes without saying that for everyone Blanket cylinder 2 to 5 a separate arrangement for Preventing damage to the printing unit is required, whereby yes already a cylinder 57 to operate 2 to 5 per blanket cylinder per satellite printing unit must be present, as well as limit switches 38, 43. Thus, the blanket cylinders 2, 3 (Fig. 2) be pivoted that these are neither contact with each other own, still in contact with the plate cylinder 7, 8 are.

    Weiterhin ist es möglich, die Gummituchzylinder 4, 5 in eine weitere dritte Stellung zu verschwenken, die hinter der Druckabstellung 4, 1; 5, 1 liegt, in welcher sich dann die Gummituchzylinder 4, 5 berühren (analog der Zylinder 2, 3 in Fig. 2). It is also possible to use the blanket cylinders 4, 5 in to pivot another third position, the one behind the print stop 4, 1; 5, 1 lies in which then touch the blanket cylinders 4, 5 (similar to the Cylinder 2, 3 in Fig. 2).
