Description

Die Erfindung betrifft eine Vorrichtung zur lösbaren Befestigung eines Transportbandträgers einer drucktechnischen Maschine, wobei der dem Transport von Drucksubstraten dienende Transportbandträger für Servicezwecke von den mit ihm zusammenwirkenden Funktionselementen wegbewegbar ist.The invention relates to a device for releasably attaching a conveyor belt carrier a printing machine, the transport of printing substrates serving conveyor belt carriers for service purposes from those interacting with it Functional elements can be moved away.

Transportbandträger dienen im wesentlichen zur Aufnahme eines Transportbandes, Führungen desselben, eines Antriebes sowie meistens auch von Steuerungs- und Sensorelementen, sowie Elementen, die für Anpreßkräfte an Zylindern sorgen. Die durch das Transportband geführten Drucksubstrate können von der drucktechnischen Maschine meßtechnisch erfaßt oder bearbeitet werden. Dazu befinden sich oberhalb der geführten Drucksubstrate Funktionselemente, die zu den vorgenannten Zwecken mit dem Transportband zusammenwirken. Bei einer Druckmaschine, in der Regel einer elektrophotografischen Druckmaschine, handelt es sich dabei um Druckmodule, die die Drucksubstrate mittels Zylinder mit Teilfarbenbildern bedrucken, die zusammen den Farbdruck ergeben. Zusätzlich können natürlich noch weitere Sensor-, Steuerungs- oder Bearbeitungselemente angeordnet sein.Conveyor belt carriers essentially serve to hold a conveyor belt, guides the same, a drive and usually also control and sensor elements, as well as elements that provide contact pressure on cylinders. The through that Conveyor belt-guided printing substrates can be fed from the printing machine measured or processed. For this are located above the guided Printing substrates Functional elements for the aforementioned purposes with the conveyor belt work together. For a printing press, usually an electrophotographic Printing press, these are printing modules that support the printing substrates print with partial color images using cylinders, which together form the color print surrender. In addition, of course, other sensor, control or processing elements be arranged.

Für Servicearbeiten ist es erforderlich den Transportbandträger mit dem Transportband von den vorgenannten Funktionselementen zu trennen. Dies kann beispielsweise dazu dienen, einen Papierstau zu beseitigen, das Transportband auszuwechseln oder an Funktionselemente heranzukommen, die in diesem Bereich angeordnet sind. Zu diesem Zweck wurde vorgeschlagen, die über dem Transportbandträger befindlichen Maschinenteile wegzuklappen. Dies ist insbesondere bei anspruchsvollen Maschinen, in denen diese Maschinenteile eine gewisse Größe aufweisen, nicht praktikabel. Es wurde auch vorgeschlagen, den Transportbandträger ausbaubar auszugestalten oder ihn mittels vertikaler oder horizontaler Führungen aus der Maschine herauszufahren. Die letztgenannten Vorschläge sind bei großen Maschinen, insbesondere, wenn die Transportbänder und daher auch dessen Träger eine gewisse Länge aufweisen, ebenfalls nicht praktikabel. In jedem Fall sind Transportbandträger der vorgenannten Art schwierig zu handhaben und daher meist nur von geschulten Servicetechnikern und nicht von Bedienpersonen handhabbar. Bei diesen Lösungen ist es auch schwierig, eine exakte Positionierung eines Transportbandträgers für die Arbeitsposition wieder herzustellen, meist muß eine Justierung vorgenommen werden.The conveyor belt carrier with the conveyor belt is required for service work to separate from the aforementioned functional elements. This can be done, for example serve to clear a paper jam, to replace the conveyor belt or to functional elements approach that are arranged in this area. To this Purpose was proposed to the machine parts located above the conveyor belt carrier fold away. This is particularly the case with demanding machines in which these machine parts are of a certain size, not practical. It was too proposed to design the conveyor belt removable or by means of to move vertical or horizontal guides out of the machine. The latter Suggestions are for large machines, especially if the conveyor belts and therefore its carrier also have a certain length, also not practical. In any case, conveyor belt carriers of the aforementioned type are difficult to handle and therefore mostly only by trained service technicians and not by Operators easy to handle. With these solutions, it is also difficult to get an exact one To restore positioning of a conveyor belt carrier for the working position, usually an adjustment has to be made.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art derart auszugestalten, daß der Transportbandträger einfach wegbewegbar und exakt in die Arbeitsposition zurückbringbar ist.The invention is therefore based on the object of a device at the outset mentioned type in such a way that the conveyor belt carrier can be easily moved away and can be brought back exactly to the working position.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Transportbandträger an einer Längsseite schwenkbar an der drucktechnischen Maschine angelenkt ist, derart, daß er in mindestens eine Serviceposition und eine Arbeitsposition schwenkbar und in letzterer festlegbar ist.The object is achieved in that the conveyor belt carrier a long side is pivotally connected to the printing machine, such that it can be pivoted into at least one service position and one working position and into the latter can be determined.

Durch die erfindungsgemäße Schwenkbewegung können auch schwere und lange Transportbandträger auf einfache Weise wegbewegt werden, um einen Papierstau zu entfernen, das Transportband zu wechseln oder Servicearbeiten durchzuführen. Durch die einfache Handhabung kann auch eine Bedienperson durch die Wegbewegung einen Papierstau entfernen oder einfache Servicearbeiten durchführen. Dadurch können viele Probleme schnell und ohne Zeitverlust behoben werden. Jedoch auch für größere Servicearbeiten ist die leichtere Zugänglichkeit der Maschine von Vorteil.The pivoting movement according to the invention can also be heavy and long Conveyor belt carriers can be easily moved away to avoid a paper jam remove, change the conveyor belt or perform service work. By the simple handling can also unite an operator by moving it Remove paper jam or perform simple service. This allows many Problems can be solved quickly and without wasting time. But also for bigger ones Service work is easier because the machine is more accessible.

Ein besonders großer Vorteil der Erfindung besteht darin, daß die Schwenkbewegung es erlaubt, den Transportbandträger wieder exakt in seine Arbeitsposition zurückzuschwenken. Dadurch entfallen Justierarbeiten, da die Schwenkbewegung derart exakt möglich ist, daß der Fehler innerhalb eines Bereichs liegt, welcher im Wege einer automatischen Registerkorrektur einer Druckmaschine auskorrigiert werden kann. Gerade diese Tatsache ermöglicht es auch, daß Bedienpersonen der Maschine einen solchen Eingriff vornehmen können, z. B. zur Beseitigung eines Papierstaus. Die erfindungsgemäße Ausgestaltung ist jedoch außer für Druckmaschinen für alle drucktechnischen Maschinen von Vorteil und ermöglichen eine einfache und gute Zugänglichkeit zu vielen Teilen der Maschinen.A particularly great advantage of the invention is that the pivoting movement there allows the conveyor belt carrier to be pivoted back exactly into its working position. This eliminates adjustment work, because the swivel movement is so precise it is possible that the error is within a range which is automatic Register correction of a printing press can be corrected. Just this fact also enables operators of the machine to do so Can make intervention, for. B. to clear a paper jam. The invention Design is, however, except for printing presses for all printing technology Machines are advantageous and allow easy and good accessibility many parts of the machines.

Zweckmäßigerweise wird mindestens ein Anschlag vorgesehen, durch den die Arbeitsposition exakt definiert ist. Dadurch ist es möglich, diese Position innerhalb kleinster Toleranzen wiederzufinden und dabei eine absolut parallele Lage zu erzielen. Weiterhin wird vorgeschlagen, daß mindestens eine Arretiervorrichtung der Festlegung des Transportbandträgers in der Arbeitsposition dient. Auf diese Weise kann das Transportband mit hohen Anpreßkräften beaufschlagt werden, die beispielsweise für einen Qualitätsdruck erforderlich sind.At least one stop is expediently provided, through which the working position is exactly defined. This makes it possible to position this within smallest Find tolerances again and achieve an absolutely parallel position. Farther it is proposed that at least one locking device fixing the conveyor belt carrier serves in the working position. In this way, the conveyor belt with high contact forces, for example for quality printing required are.

Eine Weiterbildung der Erfindung sieht vor, daß mindestens ein die Schwenkbewegung unterstützendes Element vorgesehen ist. Dieses Element wird zweckmäßigerweise derart ausgebildet, daß das Transportträgerband leicht in jede Position verbringbar ist. Es kann dabei derart ausgebildet sein, daß der Transportbandträger in jeder Position einen Selbsthalt aufweist und/oder daß er in jeder Position festlegbar ist.A further development of the invention provides that at least one pivotal movement supporting element is provided. This element is useful formed such that the conveyor belt can be easily moved into any position. It can be designed such that the conveyor belt carrier in any position has a self-hold and / or that it can be fixed in any position.

Ein die Schwenkbewegung unterstützendes Element kann aus mindestens einer Feder, beispielsweise einer Gasdruckfeder bestehen. Es kann jedoch auch mindestens eine arretierbare Gasdruckfeder vorgesehen sein. Die genannten Element mit ihren verschiedenen Funktionen können jedoch auch miteinander kombiniert sein, beispielsweise Federn und arretierbare Dämpfer. Dadurch läßt sich das Transportträgerband außer in die Arbeitsposition in verschiedene Servicepositionen bewegen und dort arretieren, um unterschiedliche Zugänglichkeiten für verschieden Arbeiten zu erreichen. An element supporting the pivoting movement can be made of at least one spring, for example, a gas pressure spring. However, it can also be at least one lockable gas pressure spring can be provided. The mentioned item with its different However, functions can also be combined with one another, for example Springs and lockable dampers.

Fig. 1 zeigt einen Querschnitt einer drucktechnischen Maschine 2 mit der erfindungsgemäßen Anlenkung 15 eines Transportbandträgers 1 an das Maschinengehäuse 13. Bei der drucktechnischen Maschine 2 handelt es sich um eine elektrophotografische Druckmaschine, bei der oberhalb des Transportbandträgers 1 Druckmodule 12 angeordnet sind. Von diesen Druckmodulen 12 erstreckt sich das Maschinengehäuse 13 L-förmig nach unten und weist dort einen Fuß 14 auf. Dadurch entsteht ein Freiraum 26, in dem der an seiner Längsseite 5 an das Maschinengehäuse 13 angelenkte Transportbandträger 1 geschwenkt werden kann. Dabei ist die obere waagerechte Position die Arbeitsposition 7. Alle anderen Positionen 6, 6' sind Servicepositionen, wobei die unterste Position 6 die beste Zugänglichkeit für größere Arbeiten ermöglicht. Es sind jedoch alle anderen Zwischenpositionen möglich. Durch die Servicepositionen 6, 6' ist es möglich, Papierstaus zu beseitigen, das Transportband 18 zu wechseln oder an Funktionselemente 4, dies können die Druckmodule 12 oder andere Funktionselemente 4 sein, heranzukommen, die mit dem Transportband 18 zusammenwirken. 1 shows a cross section of a printing machine 2 with the articulation 15 according to the invention of a conveyor belt carrier 1 to the machine housing 13. The printing machine 2 is an electrophotographic printing machine in which 1 printing modules 12 are arranged above the conveyor belt carrier. From these pressure modules 12, the machine housing 13 extends downward in an L-shape and has a foot 14 there. This creates a free space 26 in which the conveyor belt carrier 1 articulated on its longitudinal side 5 to the machine housing 13 can be pivoted. The upper horizontal position is the work position 7. All other positions 6, 6 'are service positions, the lowest position 6 providing the best accessibility for larger jobs. However, all other intermediate positions are possible. The service positions 6, 6 'make it possible to clear paper jams, to change the conveyor belt 18 or to access functional elements 4, which can be the printing modules 12 or other functional elements 4, which interact with the conveyor belt 18.

Mindestens ein Anschlag 8 und mindestens eine Arretiervorrichtung 9 sorgen dafür, daß der Transportbandträger 1 in seiner Arbeitsposition 7 sicher und exakt positioniert ist. Die Arretiervorrichtung 9 ist lediglich symbolisch dargestellt, sie kann auf verschiedenste Weise ausgebildet sein. Beispielsweise kann sie ein Gegenlager 11 der Arretiervorrichtung 9, welches am Transportbandträger 1 angeordnet ist, festlegen. Dadurch ist der Transportbandträger 1 mit hohen Kräften beaufschlagbar, was insbesondere dann erforderlich ist, wenn eine Bedruckung von Drucksubstraten 3 vorgenommen wird.At least one stop 8 and at least one locking device 9 ensure that the conveyor belt carrier 1 is securely and precisely positioned in its working position 7. The locking device 9 is only shown symbolically, it can be in a variety of ways Be trained. For example, it can be a counter bearing 11 of the locking device 9, which is arranged on the conveyor belt carrier 1, set. This is the conveyor belt carrier 1 can be subjected to high forces, which is particularly the case is necessary when printing on printing substrates 3 is carried out.

Um den Transportbandträger 1 in seine verschiedenen Positionen 6, 6', 7 zu verbringen, ist es zweckmäßig, wenn eine Element 10 angeordnet ist, das die Schwenkbewegung unterstützt. Es kann sich dabei um eine Feder, eine Gasdruckfeder, ein Dämpfüngselement oder ein arretierbares Element handeln. Dargestellt ist eine Gasdruckfeder, welche eine Anlenkung 17 am Transportbandträger 1 und eine Anlenkung 16 am Maschinengehäuse aufweist. Durch die Gasdruckfeder läßt sich der Transportbandträger 1 leichter nach oben bewegen und in der umgekehrten Richtung verlangsamt sie eine selbständige oder zu schnelle Bewegung des Transportbandträgers 1 nach unten, wenn die Arretiervorrichtung 9 gelöst wird. Das Element 10 kann auch derart ausgebildet sein, daß der Transportbandträger 1 in jeder Position einen Selbsthalt aufweist. Auch eine Arretierung kann vorgesehen sein.

Bezüglich der bereits zu Fig. 1 beschriebenen Elemente wird auf die obige Beschreibung verwiesen. In dieser Darstellung ist der Transportbandträger 1 näher dargestellt, wobei es sich jedoch auch hier um eine Prinzipdarstellung handelt, in der beispielsweise Papiervorräte, Papierzuführung und sonstige Bauteile eine elektrofotografischen Druckmaschine der Einfachheit halber weggelassen wurden. Prinzipiell dargestellt ist die Papierlaufbahn 20, welche in Bereichen, in denen ein Zusammenwirken mit den Druckmodulen 12 stattfindet, als Transportband 18 ausgebildet ist. Dieses wird von Führungsrollen 19 geführt, wobei mindestens eine dieser Rollen 19 als Antriebsrolle füngiert. Dadurch werden die Drucksubstrate 3 in Richtung des Pfeils 21 transportiert und dabei bedruckt. Nach dem Transportband 18 ist eine Weiche 22 angeordnet, welche die bedruckten Drucksubstrate 3 entweder einer Blattausgabe 23 oder einer Blattrückführung 24 zuleiten. Die Blattrückführung 24 bezweckt die Bedruckung der Rückseite der Drucksubstrate 3, wobei zu diesem Zweck eine Wendeeinrichtung 25 angeordnet ist. Fig. 2 shows a side view of the electrophotographic printing machine 2 acc. Fig. 1 with a conveyor belt carrier 1, which is shown cut open lengthways. With regard to the elements already described for FIG. 1, reference is made to the above description. In this illustration, the conveyor belt carrier 1 is shown in more detail, although this is also a basic illustration in which, for example, paper supplies, paper feed and other components of an electrophotographic printing machine have been omitted for the sake of simplicity. In principle, the paper track 20 is shown, which is designed as a conveyor belt 18 in areas in which there is interaction with the printing modules 12. This is guided by guide rollers 19, with at least one of these rollers 19 acting as the drive roller. As a result, the printing substrates 3 are transported in the direction of the arrow 21 and printed in the process. Arranged after the conveyor belt 18 is a switch 22 which feeds the printed printing substrates 3 either to a sheet output 23 or to a sheet return 24. The sheet return 24 has the purpose of printing on the back of the printing substrates 3, with a turning device 25 being arranged for this purpose.

In dieser Darstellung befindet sich der Transportbandträger 1 in seiner Arbeitsposition 7 und ist dabei durch die bereits beschriebene Arretiervorrichtung 9 gehalten, welche in dieser Darstellung nicht zu sehen ist.In this illustration, the conveyor belt carrier 1 is in its working position 7 and is held by the locking device 9 already described, which in this representation cannot be seen.
