Description

Die Erfindung betrifft eine Speichertrommel in Wendeeinrichtungen von Bogendruckmaschinen.
Nach dem Prinzip der Drei-Trommel-Wendung arbeitende Wendeeinrichtungen bestehen aus drei Bogenführungszylindern, von denen der mittlere als Speichertrommel mit doppelt-großem Durchmesser ausgebildet ist.
The invention relates to a storage drum in turning devices of sheet-fed printing machines.
Turning devices working according to the principle of the three-drum turn consist of three sheet guide cylinders, of which the middle one is designed as a storage drum with a double-large diameter.

Die drei Bogenführungszylinder der Wendeeinrichtung sind zwischen zwei Druckzylindern angeordnet. Eine derartige Wendeeinrichtung ermöglicht die Wendung des Bogens nach dem Prinzip der Bogenhinterkantenwendung und damit die Aufbringung eines Schön- und Widerdruckes auf den Bogen in einem Durchlauf.The three sheet guide cylinders of the turning device are between two impression cylinders arranged. Such a turning device enables the sheet to be turned the principle of the trailing edge of the sheet and thus the application of a beautiful and Backprint on the sheet in one pass.

Der Speichertrommel vorgeordnet ist ein Bogenführungszylinder mit üblicherweise einfach-großem Durchmesser, der Speichertrommel nachgeordnet ist die Wendetrommel mit einfach-großem Durchmesser.Upstream of the storage drum is a sheet guiding cylinder with usually a single-large one Diameter, downstream of the storage drum, is the reversing drum with a single-large one Diameter.

Die Speichertrommel weist jeweils zwei Bogenhaltesysteme für den vorderen und hinteren Bereich des Bogens auf. Dabei liegen die Bogenhaltesysteme für den vorderen Bereich und die Bogenhaltesysteme für den hinteren Bereich sich jeweils diametral gegenüber.The storage drum has two sheet retention systems for the front and rear Area of the arch. The bow support systems for the front area and the bow support systems for the rear area are diametrically opposed to each other.

Bei Betriebsartwechsel-Umstellung von Schöndruck auf Schön- und Widerdruck und umgekehrt bzw. bei 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 relativ zueinander zu verstellen.When changing the operating mode from straight to perfect and reverse printing or when processing sheets of a different sheet length in straight printing or in Fine and reverse printing are to be carried out on the storage drum. to Setting of the sheet holding systems for processing sheets of different lengths it is necessary to keep the bow support systems for the front and rear area relative to each other to adjust.

Aus der Druckschrift DE 39 116 30 C2 ist eine Anordnung von Bogenhaltesystemen an einer Speichertrommel bekannt. Das Bogenhaltesystem für den vorderen Bereich des Bogens, das als Klemmgreifer ausgebildet ist, ist fest am Körper der Speichertrommel angeordnet. Das als Sauger ausgebildete Bogenhaltesystem für den hinteren Bereich des Bogens ist an einem Tragelement vorgesehen, das lösbar am Körper der Speichertrommel angeordnet ist. From the document DE 39 116 30 C2 is an arrangement of sheet holding systems on one Storage drum known. The bow support system for the front area of the bow, which is designed as a clamp gripper, is fixedly arranged on the body of the storage drum. The sheet holding system for the rear area of the sheet, designed as a suction cup, is on provided a support member which is detachably arranged on the body of the storage drum.

In Umfangsrichtung ist das Tragelement und damit die am Tragelement vorgesehenen Sauger mittels einer Stellwelle, die in der Trommelwelle gelagert ist, verstellbar, wobei an dem einen Ende der Stellwelle (außen) über eine Zahnradstufe ein Motor zur Betätigung der Stellwelle und am anderen Ende ein Ritzel angeordnet ist. Das Ritzel greift in ein Zahnsegment ein, das mit dem Tragelement verbunden ist. Die Stellwelle ist exzentrisch in der Trommelwelle gelagert.In the circumferential direction is the support element and thus the suction cups provided on the support element by means of an adjusting shaft which is mounted in the drum shaft, adjustable, on which one end of the control shaft (outside) via a gear stage a motor for actuating the Control shaft and a pinion is arranged at the other end. The pinion engages in a tooth segment a, which is connected to the support member. The control shaft is eccentric in the Drum shaft mounted.

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. Mit dem Tragelement werden die Sauger relativ zum Klemmgreifer verstellt.It is necessary to relative the sheet holding systems in the circumferential direction of the storage drum to adjust to each other, the control shaft is rotated via the motor and the gear stage, which acts on the support element via the pinion and the toothed segment. With the support element the suction cups are adjusted relative to the clamping gripper.

Nachteilig an einer derartigen Verstelleinrichtung der Bogenhaltesysteme ist der große Teileaufwand. Es greifen viele Getriebeglieder ineinander, die spielbehaftet sind, so dass die Einstellung der Bogenhaltesysteme auf das zu verarbeitende Bogenmaß ungenau ist. Die Bohrung und Ausfräsung in der Trommelwelle führt zu einer Schwächung des Trommelschenkels.A disadvantage of such an adjustment device of the sheet holding systems is the large amount of parts. Many gear links mesh with one another, which are subject to play, so that the Adjustment of the bow support systems to the radian to be processed is inaccurate. The drilling and milling in the drum shaft leads to a weakening of the drum leg.

Die DE 39 008 18 C1 zeigt eine Bogenführungstrommel mit einer inneren Welle und einer äußeren Trommel mit wenigstens einem gegenüber der inneren Welle in Umfangsrichtung verstellbarem Segment. Der inneren Welle und der äußeren Trommel, die durch eine Lamellenkupplung miteinander gekuppelt sind, sind die Bogenhaltesysteme zugeordnet.DE 39 008 18 C1 shows a sheet guide drum with an inner shaft and one outer drum with at least one with respect to the inner shaft in the circumferential direction adjustable segment. The inner shaft and the outer drum through a multi-plate clutch are coupled with each other, the bow holding systems are assigned.

Die Kupplung sitzt zwischen einer Stirnfläche der Segmente und einem Lagerzapfen der Welle. Über eine von außen betätigbare Spannstange und einem Klemmhebel kann die Kupplung betätigt und damit die Verbindung zwischen Welle und Segment gelöst werden. Danach sind beide mit den Bogenhaltesystemen relativ zueinander verstellbar.The coupling sits between an end face of the segments and a bearing journal Wave. Via an externally operable tension rod and a clamping lever, the Coupling actuated and thus the connection between shaft and segment can be released. Then both can be adjusted relative to each other with the bow support systems.

Nachteilig an dieser Feststell- und Löseeinrichtung ist der große Teileaufwand. Die Kupplung innerhalb der Lagerstelle des Bogenführungszylinders ist schwer zugänglich für Wartungsarbeiten bei Verschleiß und Verschmutzung. Auch in diesem Fall führt die Bohrung und Ausfräsung zu einer Schwächung des Schenkels. A disadvantage of this locking and releasing device is the large number of parts. The coupling within the storage area of the sheet guide cylinder is difficult to access for maintenance work with wear and soiling. In this case, too, the drilling and milling to weaken the thigh.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, an einer Speichertrommel in Wendeeinrichtungen die relative Winkellage der Bogenhaltesysteme zueinander mit geringem Aufwand und einfachen Mitteln zu ändern.Starting from this prior art, it is an object of the invention, on a storage drum in turning devices the relative angular position of the sheet holding systems to each other to change with little effort and simple means.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des 1. Anspruchs gelöst.According to the invention, this object is achieved by the features of claim 1.

Die erfindungsgemäße Lösung hat den Vorteil, dass mit geringem Aufwand für den Schöndruck oder für den Schön- und Widerdruck die Bogenhaltesysteme auf einer Speichertrommel in Umfangsrichtung relativ zueinander verstellt und wieder arretiert werden können. Ermöglicht wird dies durch eine Kupplung, die außerhalb der Speichertrommel liegt.The solution according to the invention has the advantage that with little effort for the straight printing or for perfecting, the sheet holding systems on a storage drum can be adjusted in the circumferential direction relative to each other and locked again. allows this is done by a clutch that is outside the storage drum.

Dabei wird in vorteilhafter Weise ein für die Phasenlageänderung bei Betriebsartwechsel oder bei Verarbeitung eines anderen Formates im Schön- und Widerdruck einsetzbarer Druckölverbund zum Lösen der Verbindung eines Doppelzahnrades genutzt.In this case, one is advantageously used for changing the phase position when the operating mode changes or when processing another format in perfecting Pressurized oil compound used to disconnect a double gear.

Zwischen den beiden Bogenhaltesystemen - Greifersystem für den Bogen im vorderen Bereich und Saugersystem für den Bogen im hinteren Bereich - ist eine Kupplung vorhanden, die durch einen Druckölverband durch Eindrücken von Öl in den Presssitz gelöst und danach die Bogenhaltesysteme relativ zueinander verstellt werden können.Between the two bow holding systems - gripper system for the bow in the front area and suction system for the bow in the rear area - there is a clutch, which is released by a pressure oil bandage by pressing oil into the press fit and then the bow support systems can be adjusted relative to each other.

Anhand eines Ausführungsbeispieles soll nachfolgend die Erfindung näher beschrieben werden.The invention will be described in more detail below using an exemplary embodiment.

A motor 37, which is fastened to the side wall 11, is via a gear stage 28, consisting of the gears 28.1, 28.1, connected to the central axis 13. The gear 28.1 is connected to the motor 37 and the gear 28.2 is connected to the central axis 13.

Ist im Schöndruck oder im Schön- und Widerdruck eine Verstellung der Bogenhaltesysteme 8, 9 relativ zueinander notwendig, wird in Ruhestellung der Druckmaschine, die an der Zentralachse 13 angreifende Bremseinrichtung 26 betätigt und damit das Saugersystem 9 der Speichertrommel 5 gegenüber der Seitenwand 11 festgesetzt.Is an adjustment of the sheet holding systems in straight printing or face and reverse printing 8, 9 necessary relative to each other, is in the rest position of the printing press, which is on the central axis 13 engaging brake device 26 actuated and thus the suction system 9 of the Storage drum 5 set against the side wall 11.

Nunmehr wird die Pumpe 29 eingeschaltet und über das Wegeventil 30, die Dreheinführung 31 und die Druckölleitung 32 wird die Verbindung Nabe/Kupplungsring 19, 20 (Presssitz 35) durch den Öldruck gelöst. Bei eingeschalteter Pumpe 29 kann nunmehr z. B. durch den nicht dargestellten Hauptantrieb der Räderzug und damit das Doppelzahnrad 14, 16 bei gegenüber der Seitenwand 11 feststehendem Saugersystem 9 die Druckmaschine durchgedreht werden. Über das Doppelzahnrad 14, 16 wird damit der Grundkörper 12 und damit das Greifersystem 8 der Speichertrommel 5 gedreht. Der Kupplungsring 20 wird dabei gleichzeitig durch den Zylinderstift 23 im Zahnkranz 16 und die Anschlagplatte 22 zur gleichermaßen feststehenden Nabe 19 verdreht.The pump 29 is now switched on and via the directional control valve 30, the rotary inlet 31 and the pressure oil line 32 becomes the connection hub / coupling ring 19, 20 (press fit 35) solved by the oil pressure. With the pump 29 switched on, z. B. by not shown main drive the gear train and thus the double gear 14, 16 at opposite the side wall 11 fixed suction system 9 the printing machine turned become. About the double gear 14, 16, the base body 12 and thus that Gripper system 8 of the storage drum 5 rotated. The coupling ring 20 is simultaneously by the cylindrical pin 23 in the ring gear 16 and the stop plate 22 for the same fixed hub 19 rotated.

Die genaue Lage der Bogenhaltesysteme 8, 9 zueinander auf der Speichertrommel 5 wird durch eine Winkelmesseinrichtung (nicht dargestellt) ermittelt.The exact position of the sheet holding systems 8, 9 relative to one another on the storage drum 5 is determined by an angle measuring device (not shown).

Nach Erreichen der Sollstellung des Bogenhaltesysteme 8, 9 wird das Wegeventil 30 geschaltet und damit der Ölstrom unterbrochen , wodurch der Presssitz 35 zwischen Nabe 19 und Kupplungsring 20 wieder hergestellt wird. Danach wird die Ölförderung der Pumpe 29 unterbrochen und die Bremswirkung der Bremseinrichtung 26 aufgehoben. After the target position of the sheet holding systems 8, 9 has been reached, the directional control valve 30 is switched and thus the oil flow is interrupted, as a result of which the press fit 35 between the hub 19 and clutch ring 20 is restored. Thereafter, the oil production of the pump 29 interrupted and the braking effect of the braking device 26 canceled.

Damit ist die Einstellung des Saugersystems 9 auf den hinteren Bereich des Bogens 7 beendet.The setting of the suction system 9 to the rear area of the sheet 7 is thus ended.

Ist ein zusätzlicher Motor 37 (Fig.4) vorhanden, wird die Kupplung 19, 20 gelöst und durch die zweite Bremseinrichtung 36 über den Schenkel 10 das Greifersystem 9 festgesetzt.
