Wesentliches Element der Erfindung ist also die Anordnung einer Wälzlagerabstützung für die Förderketten in Bereichen erhöhter Belastung, um dadurch Geräuschbildungen einzuschränken und auftretende Kräfte mit verminderter Reibung auf Laufbahnen zu übertragen, die mit dem Maschinengestell verbunden sind. Dementsprechend sind Führungen für die Laufrollen mit den Wälzlagern vorzugsweise im Bereich einer auf die Greifer des Greifersystems an den Förderketten einwirkenden Greiferöffnungskurve und im Bereich einer Förderkettenumlenkung bzw. eventuell auch im Bereich einer Förderkettenablenkung angeordnet.An essential element of the invention is the arrangement of a Rolling bearing support for the conveyor chains in areas higher Load in order to limit noise and forces occurring with reduced friction on raceways transmitted, which are connected to the machine frame. Accordingly, guides for the rollers with the Rolling bearings preferably in the area on the gripper of the Gripper system acting on the conveyor chains Gripper opening curve and in the area of a conveyor chain redirection or possibly also in the area of a conveyor chain deflection arranged.

Zur Unterstützung der durch die Erfindung angestrebten Aufgabenlösung dient ein weiteres Erfindungsmerkmal, nach dem an sich bekannte C-Profil-Kettenführungen biegeelastisch an den Seitenwänden der Druckmaschine befestigt sind. Es werden dadurch starke Stöße und damit verbundene Lärmbelästigungen bei der Einleitung der auf die Förderketten einwirkenden Kräfte in das Maschinengestell vermieden. Bei einer bevorzugten Ausführungsform einer solchen biegeelastischen Befestigung der C-Profil-Kettenführungen an den Seitenwänden ist auf einem Brückenteil ein Stehbolzen befestigt, wobei das Brückenteil mit zwei Schrauben, deren Achsen exzentrisch zur Stehbolzenachse angeordnet sind, an der Führung verschraubt ist und der Stehbolzen in eine Ausnehmung der Seitenwand hineinragt. Erreicht wird dadurch eine weiche Befestigung des C-Profils für die Kettenführungen an dem Maschinengestell, durch die harte, auf die Förderketten einwirkende Belastungsschläge gedämpft werden.To support those sought by the invention Task solution serves another inventive feature, according to the known C-profile chain guides are flexible to the Side walls of the printing press are attached.

An der Innenseite der Seitenwände 1 des Maschinengestells sind auf beiden Maschinenseiten Kettenführungen 2 für eine endlos umlaufend angetriebene Förderkette 3 befestigt. An den beiden somit parallel nebeneinander umlaufenden Förderketten 3 sind in regelmäßigen Abständen Greifersysteme 4 aus einer an beiden Förderketten befestigten Greiferbrücke 5 und daran angeordneten Bogengreifern 6 befestigt. In der Figur 3 sind Bogengreifer aus einem Greiferfinger 7 und einer Greiferauflage 8 dargestellt. Die Greiferfinger sind auf einer gegen eine Feder verschwenkbar angeordneten Greiferwelle 9 befestigt und wirken mit der an der Greiferbrücke 5 festen Greiferauflage 8 zusammen. Die Öffnung der Bogengreifer zur Freigabe des mit seinem Rand zwischen dem Greiferfinger 7 und der Greiferauflage 8 eingeklemmten Bogens erfolgt durch eine an der Greiferwelle 9 angeordnete, in der Zeichnung nicht dargestellte Kurvenrolle, die mit einer feststehenden Greiferöffnungskurve 10 (Figur 1) zusammenwirkt. Die Förderketten 3 werden durch Kettenräder 11 und 12 umgelenkt und sind zwischen den Umlenkungen 11 und 12 in den Kettenführungen 2 geführt. In wesentlichen Bereichen besteht die Kettenführung aus einem im Querschnitt C-förmigen Profil gemäß der Darstellung in Figur 1. Die einander gegenüberliegenden Stirnflächen des im Querschnitt C-förmigen Profils stützen die als Laschenkette ausgeführten Förderketten zwischen den seitlichen Laschen entweder gleitend an den Kettenbolzen oder abrollend an auf die Kettenbolzen aufgeschobenen Rollen ab. Der Ort der Belastungsübergabe von der Kettenführung 2 auf die Führungselemente 13 für die Laufrollen 14 oder umgekehrt ist konstruktiv durch flache Anlauf- und Auslaufwinkel gekennzeichnet.Are on the inside of the side walls 1 of the machine frame on both machine sides chain guides 2 for an endless circumferentially driven conveyor chain 3 attached. On the two thus conveyor chains 3 rotating in parallel next to each other are in regular intervals gripper systems 4 from one to both Conveyor chains attached gripper bridge 5 and arranged thereon Bow grippers 6 attached. In Figure 3, bow grippers are off a gripper finger 7 and a gripper pad 8 are shown. The Gripper fingers can be pivoted on a spring arranged gripper shaft 9 attached and act on the Gripper bridge 5 fixed gripper pad 8 together. The opening of the Bow gripper to release the with its edge between the Gripper finger 7 and the gripper pad 8 pinched sheet takes place by a arranged on the gripper shaft 9 in the Drawing cam roller, not shown, with a fixed gripper opening curve 10 (Figure 1) cooperates. The conveyor chains 3 are deflected by chain wheels 11 and 12 and are between the deflections 11 and 12 in the Chain guides 2 out. In essential areas there is Chain guide made from a cross-sectionally C-shaped profile the representation in Figure 1. The opposite End faces of the cross-sectionally C-shaped profile support the Conveyor chains designed as a link chain between the side plates either sliding on the chain pins or rolling on rollers pushed onto the chain pin. The Location of the transfer of load from the chain guide 2 to the Guide elements 13 for the rollers 14 or vice versa constructive due to flat run-in and run-out angles characterized.

In Bereichen erhöhter Belastung, vorzugsweise in den mit A und B markierten Bereichen der Förderkettenumlenkungen 11 und 12 sowie im Bereich der Greiferöffnungskurve 10 und ggf. auch an anderen Stellen erhöhter Belastung, wie zum Beispiel im Bereich C, sind zusätzliche Führungselemente 13 mit einer Laufbahn vorgesehen, gegen die sich an den Förderketten befestigte Laufrollen 14 mit einer Wälzlagerung abstützen. Gemäß der Darstellung in Figur 4 können diese Führungselemente 13 ggf. lediglich auf der Seite der Wirkungsrichtung der zusätzlichen Kräfte, wie sie beispielsweise von der Greiferöffnungskurve 10 oder von Zentrifugalkräften im Bereich der Umlenkungen 11 und 12 herrühren, angeordnet sein. Die Laufrollen 14 mit der Wälzlagerung sind bei dem Ausführungsbeispiel auf einseitig verlängerten Kettenbolzen 15 angeordnet und bestehen aus Wälzlagern, wie sie in der Schnittdarstellung in Figur 2 wiedergegeben sind. Nach dem Ausführungsbeispiel sind die Laufrollen mit der Wälzlagerung auf jeder Maschinenseite zwischen einer Förderkette und dem Stirnende der Greiferbrücke 5 vorgesehen. Vorzugsweise bilden die aus C-Profilstäben bestehenden Kettenführungen 2 und die Führungselemente 13 eine Baueinheit (Fig. 6 und 7).In areas of increased stress, preferably in areas with A and B. marked areas of the conveyor chain deflections 11 and 12 as well in the area of the gripper opening curve 10 and possibly also on others Places of increased stress, such as in area C. additional guide elements 13 are provided with a raceway, against the rollers 14 attached to the conveyor chains support a rolling bearing. As shown in Figure 4 can these guide elements 13 possibly only on the side the direction of action of the additional forces as they for example from the gripper opening curve 10 or from Centrifugal forces in the area of the deflections 11 and 12 originate, be arranged. The rollers 14 with the Rolling bearings are on one side in the embodiment elongated chain pin 15 arranged and consist of Rolling bearings, as shown in the sectional view in Figure 2 are reproduced. According to the embodiment, the Rollers with the rolling bearing on each side of the machine a conveyor chain and the front end of the gripper bridge 5 intended. They preferably form from C-shaped bars existing chain guides 2 and the guide elements 13 a Unit (Fig. 6 and 7).

Vorzugsweise sind auf jeder Maschinenseite zwei Laufrollen 14 mit Wälzlagerung in Förderrichtung hintereinander angeordnet, um Kippbewegungen des Greifersystems zu vermeiden und eine genaue Führung des Greifersystems auch unter erhöhter Belastung senkrecht zur Bogenförderrichtung zu erreichen.Preferably, two rollers 14 are on each machine side Rolling bearing arranged one behind the other in the conveying direction Avoid tilting movements of the gripper system and an accurate Guidance of the gripper system even under increased loads to reach perpendicular to the sheet conveying direction.

In weiterer Ausgestaltung der Erfindung sind für die Förderketten 3 Kettenführungen 2 vorgesehen, die entsprechend der Darstellung in Figur 5 biegeelastisch mit der jeweiligen Seitenwand 1 des Maschinengestells verschraubt sind. Erreicht wird dies durch die Zwischenschaltung eines Brückenelements 16 mit einem daran befestigten Stehbolzen 17, Zapfen oder dergleichen, der in eine im Querschnitt größer bemessene Ausnehmung 18 des Seitenteiles 1 hineinreicht und dessen Boden mit dem Boden der Ausnehmung 18 in der Seitenwand 1 durch eine Schraube 19 verschraubt ist. Das Brückenelement 16 ist exzentrisch zur Mittellängsachse des Stehbolzens 17 mit Abstand von dieser Achse an zwei Stellen mittels Schrauben 20 an der Kettenführung 2 für die Förderkette befestigt. Die Verbindung der Kettenführung 2 mit der Seitenwand 1 des Maschinengestells ist somit biegeelastisch, wobei die Elastizität durch Wahl der Abmessungen und des Werkstoffes des Brückenelements 16 bzw. des Stehbolzens 17 bestimmt werden kann.In a further embodiment of the invention are for the conveyor chains 3 chain guides 2 are provided, which correspond to the illustration in Figure 5 flexible with the respective side wall 1 of the Machine frame are screwed. This is achieved through the Interposition of a bridge element 16 with one on it fixed stud 17, pin or the like, which in a Recess 18 of the side part 1 which is larger in cross section extends in and the bottom thereof with the bottom of the recess 18 in the side wall 1 is screwed by a screw 19. The Bridge element 16 is eccentric to the central longitudinal axis of the Stud 17 at a distance from this axis in two places using screws 20 on the chain guide 2 for the Conveyor chain attached. The connection of the chain guide 2 with the Side wall 1 of the machine frame is therefore flexible, the elasticity by choice of dimensions and the Material of the bridge element 16 or the stud 17 can be determined.

In Abweichung von der Darstellung in der Figur 4 kommt die biegeelastische Verbindung der Kettenführung 2 mit dem Seitenteil 1 bevorzugt zum Einsatz, wenn für die Kettenführung an der Seitenwand 1 des Maschinengestells stabförmige C-Profil-Elemente verwendet werden, deren Verbindung mit der Seitenwand 1 gemäß dem Beispiel nach Figur 5 erfolgt.In deviation from the illustration in FIG. 4, the flexible connection of the chain guide 2 with the Side part 1 preferred for use when on the chain guide the side wall 1 of the machine frame rod-shaped C-profile elements are used, their connection to the side wall 1 according to the example of Figure 5.

Durch die Erfindungsmerkmale wird nicht nur der Verschleiß reduziert und weniger Lärm verursacht, sondern es erfolgt auch eine wesentlich geringere Schmierölbelastung, worin ein ökologisch wichtiger Vorteil liegt. Für die hochbelasteten Stellen der Kettenführung sind Wälzlager vorgesehen, so daß die geringer belasteten Führungsteile gegebenenfalls aus Kunststoff hergestellt sein können, und zwar sowohl Elemente für die Kettenführung als auch Elemente der Führung für die Wälzlager. Aus dem gleichen Grunde können eventuell anstelle von Förderketten Zahnriemen zur Anwendung kommen, da die Zugkräfte in den Fördermitteln durch die Anwendung der Erfindungsmerkmale ebenfalls reduziert werden. Zahnriemen bestehen in der Regel aus Kunststoff, erfordern weniger Schmieröl und verursachen weniger Lärm. The features of the invention are not only the wear reduced and causes less noise, but it also occurs a significantly lower lubricating oil load, in which a ecologically important advantage. For the highly stressed Locations of the chain guide roller bearings are provided so that the less stressed guide parts, possibly made of plastic can be made, both elements for the Chain guide as well as elements of the guide for the roller bearings. For the same reason, instead of Conveyor chains timing belts are used because the tensile forces in the funding through the application of the inventive features can also be reduced. Toothed belts usually consist of Plastic, require less lubricating oil and cause less Noise.
