Description
Die Erfindung betrifft eine Einrichtung zur Formatverstellung an bogenführenden Trommeln von Bogendruckmaschinen, insbesondere an Speichertrommeln in Wendeeinrichtungen, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for format adjustment on sheet-guiding drums of sheet-fed printing machines, in particular to storage drums in turning devices, according to the preamble of patent claim 1.
Zum Transport von Bogen zwischen den Druckwerken von Bogendruckmaschinen, die je eine Druckfarbe auf den Bogen aufbringen, verwendet man bogenführende Trommeln, die auch als Bogenführungszylinder bezeichnet werden. Die bogenführenden Trommeln umfassen mindestens ein Greifersystem, mit dem die Vorderkanten der Bogen ergreifbar sind. Abhängig von der Anordnung der bogenführenden Zylinder zueinander und von deren Größe kann es erforderlich werden, die Bogen auch im Bereich ihrer Hinterkanten auf der Trommel zu fixieren, bis sie an die nächste Trommel bzw. den Druckzylinder übergeben werden, wozu eine zweite, zumeist mit Saugluft arbeitende Art von Greifersystemen Verwendung findet.To transport sheets between the printing units of sheet-fed presses, each applying a printing ink to the sheet, one uses sheet-guiding drums, which are also referred to as sheet guiding cylinder. The sheet-guiding drums comprise at least one gripper system with which the leading edges of the sheets are gripped. Depending on the arrangement of the sheet-guiding cylinder to each other and their size, it may be necessary to fix the sheet in the region of their trailing edges on the drum until they are passed to the next drum or the printing cylinder, including a second, usually with suction working type of gripper systems is used.
Zur Herstellung von beidseitig bedruckten Bogen in Druckmaschinen in nur einem Arbeitsgang werden Wendeeinrichtungen eingesetzt, die mindestens eine derartige bogenführende Trommel umfassen. Beim Wendevorgang wird der jeweilige Bogen, nachdem er in den der Wendeeinrichtung vorgeordneten Druckwerken auf einer Seite bedruckt wurde, an seiner Hinterkante ergriffen und diese Hinterkante an ein der Wendeeinrichtung nachgeordnetes Druckwerk übergeben, wobei die Hinterkante zur Vorderkante wird. An den Wendegang schließt sich das Bedrucken der jeweils anderen Bogenseite an.To produce double-sided sheets in printing presses in a single operation, turning devices are used which comprise at least one such sheet-guiding drum. During the turning process, the respective sheet, after being printed on one side in the printing units upstream of the turning device, is gripped at its rear edge and transferred to the trailing edge of a printing unit downstream of the turning device, the trailing edge becoming the leading edge. The turning course is followed by the printing on the other side of the sheet.
Die Mehrheit der bekannten Wendeeinrichtungen lässt sich, abgeleitet von ihrem grundsätzlichen Aufbau, in Eintrommel- oder Dreitrommelwendeeinrichtungen einteilen.
Drei-Trommel-Wendeeinrichtungen bestehen aus drei bogenführenden Trommeln, von denen die in Bogenlaufrichtung betrachtet erste als Übergabetrommel mit einfach-großem Durchmesser, die mittlere als Speichertrommel mit doppelt-großem Durchmesser und die dritte als Wendetrommel mit einfach-großem Durchmesser ausgebildet ist. Eine derartige Wendeeinrichtung ermöglicht die Wendung des Bogens nach dem Prinzip der Bogenhinterkantenwendung und damit das wahlweise Aufbringen eines Druckbildes im Schöndruck oder im Schön- und Widerdruck. Eine doppelt-große Speichertrommel weist jeweils zwei Bogenhaltesysteme für den vorderen Bereich und zwei Bogenhaltesysteme für den hinteren Bereich des Bogens auf, die sich jeweils diametral gegenüberliegen. Bei Betriebsarten-Umstellung von Schöndruck auf Schön- und Widerdruck und umgekehrt bzw. bei der Verarbeitung von Bogen einer anderen Bogenlänge im Schöndruck oder im Schön- und Widerdruck sind an der Speichertrommel Umstellhandlungen durchzuführen. Zur Einstellung der Bogenhaltesysteme auf die Verarbeitung von Bogen unterschiedlicher Länge ist es notwendig, die Bogenhaltesysteme für den vorderen und hinteren Bereich der Bogen relativ zueinander zu verstellen, damit der Bogen im Schöndruck und im Schön- und Widerdruck am Anfang und am Ende geführt werden kann.The majority of the known turning devices, derived from their basic structure, can be divided into single-drum or three-drum turning devices.
Three-drum turning devices consist of three sheet-guiding drums, the first of which, in the direction of sheet travel, is a single-large diameter transfer drum, the middle one is a double-large diameter storage drum, and the third is a single-diameter rotary drum. Such a turning device allows the turn of the sheet on the principle of Bogenhinterkantenwendung and thus the optional application of a printed image in Perfecting or perfecting. A double-sized storage drum each has two sheet holding systems for the front area and two sheet holding systems for the rear area of the sheet, which are diametrically opposed in each case. When operating mode change from Perfecting to perfecting and vice versa or when processing sheets of another sheet length in Perfecting or perfecting are on the storage drum To perform Umstellhandlungen. To set the sheet holding systems on the processing of sheets of different lengths, it is necessary to adjust the sheet holding systems for the front and rear of the sheet relative to each other, so that the sheet can be performed in straight printing and perfecting at the beginning and at the end.
Aus der Druckschrift DE 39 11 630 C2 ist eine Vorrichtung zur Formatverstellung an einer Speichertrommel bekannt. Das Bogenhaltesystem für den vorderen Bereich des Bogens, das Klemmgreifer umfasst, ist fest am Körper der Speichertrommel angeordnet. Das mit Saugluft arbeitende Bogenhaltesystem für den hinteren Bereich des Bogens ist auf einem Tragelement angeordnet, das der Speichertrommel zugeordnet ist.
In Umfangsrichtung sind das Tragelement und damit die am Tragelement angeordneten Sauger mit Hilfe einer Stellwelle, die im Zapfen der Trommelwelle exzentrisch gelagert ist, verstellbar, wobei an dem einen Ende der Stellwelle außerhalb des Maschinengestells ein Motor zur Betätigung der Stellwelle und am anderen Ende der Speichertrommel ein Ritzel angeordnet ist. Das Ritzel greift in ein Zahnsegment ein, das mit dem Tragelement verbunden ist. Ist es erforderlich, die Bogenhaltesysteme in Umfangsrichtung der Speichertrommel relativ zueinander zu verstellen, wird über den Motor und die Zahnradstufe die Stellwelle verdreht, die über das Ritzel und das Zahnsegment auf das Tragelement wirkt.From the document DE 39 11 630 C2 a device for format adjustment to a storage drum is known. The sheet holding system for the front portion of the sheet, which comprises clamping grippers, is fixedly arranged on the body of the storage drum. The sucking air sheet holding system for the rear portion of the sheet is disposed on a support member associated with the storage drum.
In the circumferential direction, the support element and thus the suction element arranged on the support element with the aid of a control shaft which is eccentrically mounted in the journal of the drum shaft, adjustable, wherein at one end of the control shaft outside the machine frame, a motor for actuating the control shaft and at the other end of the storage drum a pinion is arranged. The pinion engages in a toothed segment, which is connected to the support element. If it is necessary to adjust the sheet holding systems in the circumferential direction of the storage drum relative to each other, the adjusting shaft is rotated via the motor and the gear stage, which acts on the support element via the pinion and the toothed segment.
Die DE-PS 24 60 503 A1 offenbart eine Verstelleinrichtung mit einer Stellwelle, die die Antriebsbewegung für die Formateinstellung überträgt. Diese ist in Bezug auf die Speichertrommel axial verschiebbar zwischen einer Ruhestellung und einer Schaltposition gelagert. In der Schaltposition steht die Stellwelle über Stellritzel und eine weitere Welle mit dem als Saugleiste ausgebildeten Bogenhaltesystem für den hinteren Bereich des Bogens in Wirkverbindung, dessen Lage relativ zu dem Bogenhaltesystem für den vorderen Bereich durch Verdrehen der Stellwelle einstellbar ist.DE-PS 24 60 503 A1 discloses an adjusting device with a control shaft which transmits the drive movement for the format setting. This is mounted axially displaceable with respect to the storage drum between a rest position and a shift position. In the switching position, the actuating shaft is on actuating pinion and another shaft with the designed as suction sheet sheet holding system for the rear portion of the arc in operative connection, the position relative to the sheet holding system for the front area by turning the control shaft is adjustable.
Nachteilig an derartigen Vorrichtungen ist der große Teiteaufwand. Die verwendeten Bauelemente übertragen die Betätigungsbewegung spielbehaftet, was zur Folge hat, dass die Einstellung der Bogenhaltesysteme auf die Länge der zu verarbeitenden Bogen ungenau ist.A disadvantage of such devices is the large Teiteaufwand. The components used transfer the actuating movement with play, which has the consequence that the setting of the sheet-holding systems on the length of the sheets to be processed is inaccurate.
Die DE 39 00 818 C1 zeigt eine Bogenführungstrommel mit einer inneren Welle und einer äußeren Trommel mit wenigstens einem gegenüber der inneren Welle in Umfangsrichtung verstellbaren Segment. Der inneren Welle und der äußeren Trommel, die durch eine Lamellenkupplung miteinander gekuppelt sind, sind die Bogenhaltesysteme zugeordnet.DE 39 00 818 C1 shows a sheet guide drum with an inner shaft and an outer drum with at least one relative to the inner shaft in the circumferential direction adjustable segment. The inner shaft and the outer drum, which are coupled together by a multi-plate clutch, associated with the sheet holding systems.
Die Kupplung sitzt zwischen einer Stirnfläche der Segmente und einem Zapfen der Welle.
Über eine von außen betätigbare Spannstange und einen Klemmhebel kann die Kupplung betätigt und damit die Verbindung zwischen Welle und Segment gelöst werden. Danach sind die Bogenhaltesysteme relativ zueinander verstellbar.
Nachteilig an dieser Feststell- und Löseeinrichtung ist der große Teiteaufwand. Zur Verstellung der Bogenhaltesysteme muss die Maschine angehalten und anschließend gezielt bewegt werden.The coupling is seated between an end face of the segments and a journal of the shaft.
The clutch can be actuated via an externally actuated tension rod and a clamping lever, thus releasing the connection between shaft and segment. Thereafter, the sheet holding systems are adjustable relative to each other.
A disadvantage of this locking and releasing device is the large Teiteaufwand. To adjust the sheet holding systems, the machine must be stopped and then selectively moved.
Der Erfindung liegt die Aufgabe zugrunde, unter Vermeidung der vorgenannten Nachteile eine Einrichtung zur Formatverstellung an bogenführenden Trommeln von Bogendruckmaschinen, insbesondere an Speichertrommeln in Wendeeinrichtungen zu schaffen, die die Einstellung der Bogenhaltesysteme auf die Formatlänge bei laufender Maschine ermöglicht und die Einstellgenauigkeit verbessert.The invention has for its object to provide while avoiding the aforementioned disadvantages, a device for format adjustment to sheet-guiding drums of sheetfed presses, especially on storage drums in turning facilities, which allows the setting of the sheet holding systems on the format length while the machine is running and improves the setting accuracy.
Erfindungsgemäß wird diese Aufgabe mit einer Einrichtung der eingangs genannten Art gelöst, die die Merkmale des Patentanspruchs 1 aufweist.According to the invention this object is achieved with a device of the type mentioned, having the features of claim 1.
Die erfindungsgemäße Einrichtung hat den Vorteil, dass mit ihr die Formatverstellung der bogenführenden Trommel in einfacher Weise durch ein Verschieben des Betätigungselements bewirkt werden kann, wozu die Maschine nicht angehalten werden muss.
Die geradlinige Betätigungsbewegung wird von dem Betätigungselement, das das Antriebsglied eines Getriebes bildet, auf den Trägerkörper übertragen, wobei die geradlinige Bewegung zu einer Drehbewegung transformiert wird. Als Getriebe kann ein räumliches Koppelgetriebe vorgesehen sein. Zur Übertragung und Transformation der Betätigungsbewegung werden dabei ausschließlich einfach zu fertigende Getriebeglieder in Form einer Schubstange, einer Kurbelwelle und von zwei Koppeln benötigt, die mit Drehgelenken verbunden sind, welche ein geringes Lagerspiel aufweisen. Dies ermöglicht eine genaue Einstellung der Bogenhaltesysteme auf die Formatlänge der zu bedruckenden Bogen und gewährleistet insbesondere aufgrund der Robustheit der Getriebeglieder eine hohe Betriebssicherheit der Wendeeinrichtung.
Das Getriebe ist gemäß einer vorteilhaften Ausführungsform selbsthemmend ausgebildet. Der daraus resultierende Vorteil besteht darin, dass ein derartiges Getriebe neben der Übertragung der Betätigungsbewegung auch eine Fixierung bewirkt, weswegen zusätzliche Klemmeinrichtungen entfallen können.The device according to the invention has the advantage that with it the format adjustment of the sheet-guiding drum can be effected in a simple manner by a displacement of the actuating element, for which the machine does not have to be stopped.
The rectilinear actuating movement is transmitted from the actuating element, which forms the drive member of a transmission, on the carrier body, wherein the rectilinear motion is transformed into a rotational movement. As a transmission, a spatial coupling mechanism can be provided. For transmission and transformation of the actuating movement only gear members to be produced in the form of a push rod, a crankshaft and two couplings are needed, which are connected to swivel joints, which have a small bearing clearance. This allows a precise adjustment of the sheet holding systems on the format length of the sheets to be printed and ensures, in particular due to the robustness of the gear members high reliability of the turning device.
The transmission is self-locking according to an advantageous embodiment. The resulting advantage is that such a transmission in addition to the transmission of the actuating movement causes a fixation, which is why additional clamping devices can be omitted.
Bei einer Weiterbildung der Erfindung ist das Betätigungselement drehentkoppelt mit einem Antrieb verbunden, der eine Betätigungsbewegung erzeugt, so dass eine automatische Umstellung der bogenführenden Trommel vornehmbar ist.In a further development of the invention, the actuating element is connected in a rotationally coupled manner to a drive which generates an actuating movement, so that an automatic changeover of the sheet-guiding drum can be undertaken.
Dem Betätigungselement kann bei einer weiteren Ausgestaltung der Erfindung ein Sensor, der die Lage des Betätigungselement erfasst, zugeordnet sein, wodurch die Stellung der Bogenhaltesysteme zueinander in einfacher Weise abgefragt bzw. überwacht werden kann.In a further embodiment of the invention, the actuating element can be associated with a sensor which detects the position of the actuating element, as a result of which the position of the sheet-holding systems can be interrogated or monitored in a simple manner.
Anhand eines Ausführungsbeispieles soll nachfolgend die Erfindung am Beispiel einer bogenführenden Trommel näher beschrieben werden, die als Speichertrommel einer Drei-Trommel-Wendeeinrichtung ausgebildet ist.Reference to an exemplary embodiment, the invention will be described below using the example of a sheet-guiding drum, which is designed as a storage drum of a three-drum turning device.

Ist die Umstellung der Speichertrommel 5 erforderlich, wird die Schubstange von einem Antrieb, der eine geradlinige Betätigungsbewegung erzeugt, in der im Zapfen 12 ausgebildeten Durchgangsbohrung entlang der Mittellängsachse des Trommelgrundkörpers 11 verschoben.
Die am Ende der Schubstange angelenkte erste Koppel 20 überträgt die Bewegung über den ersten Hebel 21 auf die am Trommelgrundkörper 11 gelagerte Kurbelwelle 22, die in eine Drehbewegung versetzt wird. Über die mit ihrem einen Ende am zweiten Hebel 23 angelenkte zweite Koppel 24, deren anderes Ende in radialem Abstand zur Drehachse des drehbar auf dem Trommelgrundkörper 11 gelagerten Trägerkörpers 19 angreift, wird der Trägerkörper 19 bezüglich des Trommelgrundkörpers 11 verdreht und damit die Lage der Bogenhaltesysteme 8, 9 für den vorderen und hinteren Bereich zueinander eingestellt.
Die Erfindung wurde anhand einer Speichertrommel 5 in einer Wendeeinrichtung 1 beschrieben. Sie ist jedoch auch an bogenführenden Trommeln in reinen Schöndruckmaschinen für die Führung des Bogens 7 im hinteren Bereich einsetzbar, insbesondere wenn diese doppeltgroß ausgebildet sind.If the changeover of the
