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 it has been printed on one side in the printing units upstream of the turning device, is gripped at its trailing 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 Ein-Trommel- oder Drei-Trommel-Wendeeinrichtungen 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 known turning devices, derived from their basic construction, can be divided into single-drum or three-drum turning devices. Three-drum turning devices consist of three sheet-guiding drums, the first viewed in the sheet running direction, as a single-diameter transfer drum, the middle as a double-large diameter storage drum, and the third as 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 a sheet other sheet length in Perfecting or perfecting are on the storage drum Umstellhandlungen perform. 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. Die Stellwelle ragt durch eine Bohrung im Wellenzapfen der Trommelwelle und trägt an beiden Seiten Ritzel. Das dem Tragelement zugewandte Ritzel der Stellwelle kämmt mit einem am Tragelement angeordneten Zahnsegment. Das andere Ritzel steht mit einem außerhalb der Gestellwand koaxial zur Trommelwelle angeordneten weiteren Ritzel im Eingriff. Ebenfalls außerhalb der Gestellwand ist ein Motor angeordnet, der mit dem weiteren Ritzel kuppelbar ist. Zur Formatverstellung wird zunächst der Motor mit dem koaxial angeordneten Ritzel verkuppelt, das von dem Motor in Drehbewegung versetzt wird und über die Stellwelle die mit dieser verbundenen Ritzel und das Zahnsegment den Trägerkörper antreibt.
Die DE 10122227A1 offenbart eine Speichertrommel, wobei die relative Winkellage der Bogenhaltesysteme zueinander mit geringem Aufward und einfachen Mitteln zu ärdern sind.
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.
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 by means of an adjusting shaft, which is mounted eccentrically in the journal of the drum shaft, adjustable. The actuating shaft protrudes through a hole in the shaft journal of the drum shaft and carries pinions on both sides. The support element facing the pinion of the control shaft meshes with a toothed segment arranged on the support element. The other pinion engages with a further pinion disposed coaxially with the drum shaft outside the frame wall. Also outside the frame wall, a motor is arranged, which can be coupled with the other pinion. For format adjustment, the motor is first verkuppelt with the coaxially arranged pinion, which is offset by the motor in rotary motion and drives the carrier body via the actuating shaft connected to this pinion and the toothed segment.
DE 10122227A1 discloses a storage drum, wherein the relative angular position of the sheet holding systems to each other with little upwards and simple means are to be changed.
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 Teileaufwand. 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 parts cost. 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.
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 beide Bogenhaltesysteme relativ zueinander verstellbar.
Nachteilig an dieser Feststell- und Löseeinrichtung ist der große Teileaufwand. Zur Verstellung der Bogenhaltesysteme muss die Maschine angehalten und anschließend gezielt bewegt werden.
Der Erfindung liegt die Aufgabe zugrunde, eine Einrichtung zur Formatverstellung an bogenführenden Trommeln von Bogendruckmaschinen, insbesondere an Speichertrommeln in Wendeeinrichtungen zu schaffen, die bei geringem Teileaufwand die Einstellung der Bogenhaltesysteme auf die Formatlänge bei laufender Maschine ermöglicht.
DE 39 00 818 C1 shows a sheet guiding drum with an inner shaft and an outer drum with at least one opposite 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.
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, both sheet holding systems are adjustable relative to each other.
A disadvantage of this locking and releasing device is the large parts cost. To adjust the sheet holding systems, the machine must be stopped and then selectively moved.
The invention has for its object to provide a device for format adjustment to sheet-guiding drums of sheet-fed presses, especially on storage drums in turning facilities that enables the setting of the sheet holding systems on the format length while the machine is running with low parts cost.

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. Das Betätigungselement ist über ein hydraulisches Getriebe mit dem Trägerkörper derart wirkverbunden, dass dieser durch Verschieben des Betätigungselements verdrehbar ist. Das hydraulische Getriebe ist in einfachster Weise als geschlossenes System aufgebaut und besteht im Wesentlichen aus zwei Hydraulikzylindern, von denen einer als Hydropumpe und der andere als Hydromotor wirkt. Zwischen den Hydraulikzylindern wird die Betätigungsbewegung allein von einem Druckmittel, das in die, Hydraulikzylinder miteinander verbindende Leitungen geführt wird, übertragen. Die vorzugsweise flexibel ausgeführten Leitungen sind leicht zu verlegen, benötigen keine Lagerstellen und ersetzen auf diese Weise verwendet, die bekannten mechanischen Getriebeglieder.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 actuating element is operatively connected via a hydraulic transmission to the carrier body such that it is rotatable by displacement of the actuating element. The hydraulic transmission is constructed in the simplest way as a closed system and consists essentially of two hydraulic cylinders, one of which acts as a hydraulic pump and the other as a hydraulic motor. Between the hydraulic cylinders, the actuating movement is transmitted solely by a pressure medium, which is guided into the, hydraulic cylinder interconnecting lines. The preferably flexibly designed lines are easy to install, require no bearings and replace used in this way, the known mechanical gear members.

Die Hydraulikzylinder können einfach- oder doppeltwirkend ausgeführt sein. Bei Verwendung von einfachwirkenden Hydraulikzylindern sind zur Rückstellung der Kolben Rückholfedern vorgesehen, die in den Hydraulikzylindern integriert oder zwischen Trommelgrundkörper und Trägerkörper angeordnet sein können. Doppeltwirkende Hydraulikzylinder weisen den Vorteil auf, dass mit ihnen in beiden Arbeitsrichtungen und damit Richtungen der Formatverstellung verhältnismäßig große Kräfte und dem Betrag nach gleiche Kräfte aufgebracht werden können. Werden an den Hydraulikzylindern zudem beidseitige Kolbenstangen ausgebildet, ergibt sich in beiden Richtungen die gleiche Volumenänderung pro Kolbenweg.The hydraulic cylinders can be simple or double acting. When using single-acting hydraulic cylinders return springs are provided for returning the piston, which can be integrated in the hydraulic cylinders or arranged between the drum body and carrier body. Double-acting hydraulic cylinders have the advantage that with them in both working directions and thus directions of the format adjustment relatively large forces and the amount equal forces can be applied. If two-sided piston rods are also formed on the hydraulic cylinders, the same volume change per piston travel results in both directions.

Der zweite Hydraulikzylinder kann neben der dargestellten Bauform des Schubkolbenzylinders auch als Drehkolbenzylinder ausgebildet und über geeignete Übertragungsglieder mit dem Trägerkörper verbunden sein.The second hydraulic cylinder can be formed in addition to the illustrated design of the thrust piston cylinder as a rotary piston cylinder and connected via suitable transmission elements with the carrier body.

Nach einer Weiterbildung der Erfindung sind die Übertragungsflächen des Kolbens des ersten Hydraulikzylinders, also die Flächen in denen das Druckmittel am Kolben angreift, größer ausgeführt als die Übertragungsflächen des Kolbens des zweiten Hydraulikzylinders. Damit wird in vorteilhafter Weise die Übersetzung des hydraulischen Getriebes derart eingestellt, dass mit kleinen Wegen des Betätigungsgliedes verhältnismäßig große Verstellwege des Trägerkörpers realisierbar sind.According to a development of the invention, the transfer surfaces of the piston of the first hydraulic cylinder, that is to say the surfaces in which the pressure medium acts on the piston, are made larger than the transfer surfaces of the piston of the second hydraulic cylinder. Thus, the ratio of the hydraulic transmission is adjusted in such an advantageous manner that relatively small adjustment paths of the carrier body can be realized with small paths of the actuator.

Nach einer anderen Weiterbildung der Erfindung bildet die Kolbenstange des ersten Hydraulikzylinders das Betätigungselement.According to another embodiment of the invention, the piston rod of the first hydraulic cylinder forms the actuating element.

Das Druckmittel ist gemäß einer weiteren Weiterbildung der Erfindung wasserbasiert und es kann Glyzerin enthalten, das die Korrosionsgefahr vermindert. Die Verwendung eines wasserbasierten Druckmittels hat den Vorteil, dass aus dem geschlossenen System austretendes und über ein Druckmittelspeichersystem ersetzbares Druckmittel die Druckbogen nicht beschädigt. Eine wasserbasiertes Druckmittel hat den weiteren Vorteil, dass seine Zähigkeit anders als bei einem auch einsetzbaren mineralölbasierten Druckmittel weitgehend temperaturunabhängig ist.The pressure medium is water-based according to another embodiment of the invention and it may contain glycerol, which reduces the risk of corrosion. The use of a water-based pressure medium has the advantage that emerging from the closed system and replaceable via a pressure medium storage system pressure medium does not damage the sheets. A water-based pressure medium has the further advantage that, unlike a mineral oil-based pressure medium which can also be used, its toughness is largely independent of temperature.

Bei einer anderen Ausführung der Erfindung ist das Betätigungselement drehentkoppelt mit einem Antrieb verbunden, der eine Betätigungsbewegung erzeugt, so dass eine automatische Umstellung der bogenführenden Trommel vornehmbar ist. Einen das jeweils eingestellte Format repräsentierenden Wert liefert ein Sensor, der die Lage des Trägerkörpers relativ zum Trommelgrundkörper und damit die Stellung der Bogenhaltesysteme zueinander erfasst.In another embodiment of the invention, the actuating element is rotatably coupled to a drive which generates an actuating movement, so that an automatic changeover of the sheet-guiding drum is vornehmbar. A value representing the respectively set format is supplied by a sensor which detects the position of the carrier body relative to the drum base body and thus the position of the sheet holding systems relative to one another.

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.

Wie in Fig. 1 dargestellt, ist die Wendeeinrichtung 1 zwischen zwei Druckwerken einer Bogendruckmaschine angeordnet, die je einen Druckzylinder 2,2' und einen Gummizylinder 3,3' umfassen. Die Wendeeinrichtung 1 besteht, betrachtet in der mit einem Pfeil angedeuteten Bogenlaufrichtung, aus der Übergabetrommel 4 mit einfach-großem Durchmesser, der Speichertrommel 5 mit doppelt-großem Durchmesser und der Wendetrommel 6 mit einfach-großem Durchmesser. Die Speichertrommel 5 ist mit je zwei Bogenhaltesystemen 8, 9 für den vorderen und den hinteren Bereich der Bogen 7 ausgestattet.
Die Bogenhaltesysteme 8 für den vorderen Bereich sind als Greifersystem und für den hinteren Bereich als Saugersystem ausgebildet. Greifersystem und Saugersystem sind in Umfangsrichtung zueinander verstellbar, so dass die Bogen 7 vom maximalen bis zum minimalen Format im vorderen und hinteren Bereich auf der Speichertrommel 5 gehalten werden können. Die Druckzylinder 2,2' weisen einen doppelt-großen Durchmesser auf, können aber auch mit einfach-großem Durchmesser ausgeführt sein. Die Greifer- und Saugersysteme liegen sich in der Speichertrommel 5 jeweils diametral gegenüber.
As shown in Fig. 1, the turning device 1 is arranged between two printing units of a sheet-fed press, each comprising a pressure cylinder 2,2 'and a blanket cylinder 3,3' include. The turning device 1, viewed in the direction indicated by an arrow sheet travel direction, consists of the transfer drum 4 with a single-large diameter, the storage drum 5 with double-large diameter and the beater 6 with a single-large diameter. The storage drum 5 is equipped with two sheet holding systems 8, 9 for the front and the rear of the sheet 7.
The sheet holding systems 8 for the front area are designed as a gripper system and for the rear area as a suction system. Gripper system and suction system are mutually adjustable in the circumferential direction, so that the sheet 7 can be kept on the storage drum 5 from the maximum to the minimum format in the front and rear area. The printing cylinder 2,2 'have a double-large diameter, but can also be designed with a single-large diameter. The gripper and suction systems are located in the storage drum 5 each diametrically opposite.

Den detaillierten Aufbau der zwischen den Gestellwänden 10 der Druckmaschine angeordneten Speichertrommel 5 zeigt Fig. 2.
Die Speichertrommel 5 umfasst einen Trommelgrundkörper 11, an dem das Bogenhaltesystem 8 für den vorderen Bereich und vordere Bogenstützsegmente 13 angeordnet sind und einen Trägerkörper 19, der das Bogenhaltesystem 9 für den hinteren Bereich und hintere Bogenstützsegmente 14 trägt. In axialer Richtung betrachtet sind die vorderen und hinteren Bogenstützsegmente 13, 14 abwechselnd angeordnet, so dass sie sich bei Verdrehung des Trägerkörpers 19 zum Trommelgrundkörper 11 rechenartig ineinanderschieben und die Mantelfläche der Speichertrommel 5 bilden, auf der die Bogen 7 geführt werden. Der Trommelgrundkörper 11 umfasst eine hohlzylindrische Welle 12, die seitliche Zapfen 18 aufweist, über die sie drehbar in den Gestellwänden 10 gelagert ist. Ein Zapfen 18 trägt ein Antriebszahnrad 16. Der Trägerkörper 19 selbst ist drehbar auf dem Trommelgrundkörper 11 angeordnet und in axialer Richtung gegen eine Verschiebung gesichert. Die hohlzylindrische Welle 12 trägt ein entlang ihrer Mittellängsachse koaxial verschiebbares Betätigungselement 15. Das Betätigungselement 15 ist mit der Kolbenstange 31 eines ersten Hydraulikzylinders 20 verbunden. Dieser ist verdrehfest am Trommelgrundkörper 11 angeordnet und bildet zusammen mit den Leitungen 22, 23 und einem zweiten, an der Seitenscheibe 17 des Trommelgrundkörpers 11 angeordneten Hydraulikzylinder 21 ein hydraulisches Getriebe. Der erste Hydraulikzylinder 20 wirkt dabei als Hydropumpe, während der zweite Hydraulikzylinder 21 den Hydromotor des hydraulischen Getriebes bildet. Die Kolbenstange 31 des zweiten Hydraulikzylinders 21 ist am Trägerkörper 19 angelenkt. Sie erstreckt sich annähernd in Sekantenrichtung zum Querschnitt des Trommelgrundkörpers 11.
The detailed structure of the arranged between the frame walls 10 of the printing press storage drum 5 is shown in FIG. 2.
The storage drum 5 comprises a drum main body 11 on which the sheet holding system 8 for the front area and front sheet supporting segments 13 are arranged, and a support body 19 carrying the sheet holding system 9 for the rear area and rear sheet supporting segments 14. Viewed in the axial direction, the front and rear sheet support segments 13, 14 are arranged alternately, so that they merge together upon rotation of the carrier body 19 to drum main body 11 and form the lateral surface of the storage drum 5, on which the sheets 7 are guided. The drum main body 11 comprises a hollow cylindrical shaft 12 which has lateral pins 18, via which it is rotatably mounted in the frame walls 10. A pin 18 carries a drive gear 16. The carrier body 19 itself is rotatably mounted on the drum base 11 and secured in the axial direction against displacement. The hollow cylindrical shaft 12 carries an actuating element 15 which can be displaced coaxially along its central longitudinal axis. The actuating element 15 is connected to the piston rod 31 of a first hydraulic cylinder 20. This is rotationally fixed to the drum base 11 and forms together with the lines 22, 23 and a second, arranged on the side plate 17 of the drum base 11 hydraulic cylinder 21, a hydraulic transmission. The first hydraulic cylinder 20 acts as a hydraulic pump, while the second hydraulic cylinder 21 forms the hydraulic motor of the hydraulic transmission. The piston rod 31 of the second hydraulic cylinder 21 is articulated on the carrier body 19. It extends approximately in the secant direction to the cross section of the drum base body 11.

Die beiden Hydraulikzylinder 20, 21 sind vorzugsweise doppelwirkend ausgebildet und mit beidseitigen Kolbenstangen versehen, wodurch sich in beiden Bewegungsrichtungen gleiche Kräfteverhältnisse ergeben. Die Übertragungsflächen 30 des ersten Hydraulikzylinders 20 sind dabei größer ausgeführt als die Übertragungsflächen 30 des zweiten Hydraulikzylinders 21, was dem Übersetzungsverhältnis des hydraulischen Getriebes entspricht.The two hydraulic cylinders 20, 21 are preferably designed to be double-acting and provided with piston rods on both sides, resulting in equal force relationships in both directions of movement. The transfer surfaces 30 of the first hydraulic cylinder 20 are made larger than the transfer surfaces 30 of the second hydraulic cylinder 21, which corresponds to the transmission ratio of the hydraulic transmission.

Das hydraulische Getriebe ist gemäß einer nicht dargestellten Ausführungsform auch mit einfachwirkenden Hydraulikzylindern 20, 21 ausführbar. Das ermöglicht die Einsparung einer der Druckleitungen 23 bzw. 22 und erfordert eine zusätzliche Rückstellfeder.The hydraulic transmission is according to an embodiment, not shown, with single-acting hydraulic cylinders 20, 21 executable. This allows the saving of one of the pressure lines 23 and 22 and requires an additional return spring.

Abweichend von Fig. 3 kann der zweite Hydraulikzylinder 21 auch als Drehkolbenzylinder ausgebildet und über geeignete Getriebeglieder mit dem Trägerkörper 19 verbunden sein. Um das Betätigungselement 15 zu bewegen, ist außerhalb der Gestellwand 10 ein Antrieb 25 in Form eines Pneumatikzylinders oder Linearmotors angeordnet, der über einen Axiallager 26 umfassenden Drehentkoppler 27 mit dem Betätigungselement 15 verbunden ist.
Der Erfassung der Lage des Betätigungselements 15 und damit der Stellung der Bogenhaltesysteme 8, 9 zueinander, dient ein nicht dargestellter Sensor, der vorzugsweise dem Betätigungselement 15 oder der Kolbenstange 31 des ersten Hydraulikzylinders 20 zugeordnet ist.
Notwithstanding FIG. 3, the second hydraulic cylinder 21 may also be designed as a rotary piston cylinder and be connected to the carrier body 19 via suitable transmission members. To move the actuating element 15, outside the frame wall 10, a drive 25 in the form of a pneumatic cylinder or linear motor is arranged, which is connected via a thrust bearing 26 comprehensive rotary decoupler 27 with the actuating element 15.
The detection of the position of the actuating element 15 and thus the position of the sheet-holding systems 8, 9 to each other, serves a sensor, not shown, which is preferably associated with the actuating element 15 or the piston rod 31 of the first hydraulic cylinder 20.

Nachfolgend soll die Wirkungsweise der Erfindung beschrieben werden.The operation of the invention will be described below.

Ist die Umstellung der Speichertrommel 5 erforderlich, wird das Betätigungselement 15 von dem Antrieb 25, der eine geradlinige Betätigungsbewegung erzeugt, entlang der Mittellängsachse des Trommelgrundkörpers 11 verschoben. Die Bewegung des Betätigungselements 15 überträgt sich auf die Kolbenstange 31 und den Kolben 28, wodurch auf das im ersten Hydraulikzylinders 20 enthaltene Druckmittel ein Druck ausgeübt wird. Dem Verlauf der Druckleitung 22 folgend, wird dieser Druck auf den Kolben 29 übertragen und die Kolbenstange 31 des zweiten Hydraulikzylinders 21 bewegt. Das bewirkt eine Verdrehung des drehbar auf dem Trommelgrundkörper 11 gelagerten Trägerkörpers 19, an den die Kolbenstange 31 des zweiten Hydraulikzylinders 21 angelenkt ist. Mit der Verdrehung des Trägerkörpers 19 bezüglich des Trommelgrundkörpers 11 verändert sich auch die Lage der Bogenhaltesysteme 8, 9 für den vorderen und hinteren Bereich zueinander. Dieser Vorgang wird solange fortgesetzt, bis die vom Sensor gelieferten Istwerte, die die erreichte Formatverstellung repräsentieren, mit den in der Maschinensteuerung hinterlegten Sollwerten der Formatverstellung übereinstimmen.If the conversion of the storage drum 5 is required, the actuating element 15 is displaced by the drive 25, which generates a rectilinear actuating movement, along the central longitudinal axis of the drum main body 11. The movement of the actuating element 15 is transmitted to the piston rod 31 and the piston 28, whereby a pressure is exerted on the pressure medium contained in the first hydraulic cylinder 20. Following the course of the pressure line 22, this pressure is transmitted to the piston 29 and the piston rod 31 of the second hydraulic cylinder 21 is moved. This causes a rotation of the rotatable on the Drum body 11 mounted support body 19, to which the piston rod 31 of the second hydraulic cylinder 21 is articulated. With the rotation of the carrier body 19 with respect to the drum main body 11, the position of the sheet holding systems 8, 9 for the front and rear area to each other changed. This process is continued until the actual values supplied by the sensor, which represent the achieved format adjustment, correspond to the set values of the format adjustment stored in the machine control.

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.The invention has been described with reference to a storage drum 5 in a turning device 1. However, it can also be used on sheet-guiding drums in pure straight printing presses for guiding the sheet 7 in the rear region, in particular if they are double-sized.
