Description

Die Erfindung betrifft einen Riementrieb für eine flächige Bedruckstoffe verarbeitende Maschine mit einem betriebsmäßig umlaufenden endlosen Riemen, einer von dem Riemen teilweise umschlungenen Rolle, einem Rahmen, gegenüber welchem die Rolle zwischen einer den Riemen gespannt haltenden Arbeitslage und einer davon abgerückten Lage verstellbar ist, in welcher die Riemen ungespannt ist, und mit einer Federanordnung, welche die Rolle in ihre Arbeitslage vorspannt sowie eine flächige Bedruckstoffe verarbeitende Maschine, insbesondere eine Rotationsdruckmaschine, mit einer eine erste Verarbeitungsstation mit Bogen versorgenden Förderstation in Form eines Anlegers und einer von einer letzten Verarbeitungsstation übernommene Bogen einer Stapelstation zuführenden Förderstation in Form eines Auslegers und einer Ausstattung der Förderstationen mit Riementrieben.The invention relates to a belt drive for a flat substrates processing machine with an operational revolving endless Belt, one partially wrapped by the belt, one Frame against which the roller between a strained the belt keeping working position and a position off is adjustable, in which the straps is unstressed, and with a spring arrangement which the Preload role in their working position as well as a surface printing material processing machine, in particular a rotary printing press, with a a first processing station with arc supplying conveyor station in the form an investor and a company acquired from a last processing station Sheet of a stacking station feeding conveyor station in the form of a boom and equipment of the conveyor stations with belt drives.

Ein Riementrieb der genannten Art ist beispielsweise aus der Druckschrift DE 197 12 690 A1 bekannt. Eine hierin zur Vorspannung der Rolle in ihre Arbeitslage offenbarte Federanordnung ist bei einem Ausführungsbeispiel als Druckfederanordnung ausgebildet, bei welcher eine Druckfeder zwischen einem an einen Rahmen angelenkten Widerlager und einem Hebel wirksam ist, der drehfest mit einem Spannschaft in Form einer drehbar im Rahmen gelagerten Exzenterwelle verbunden ist. Ein exzentrischer Abschnitt des Spannschaftes ist unter der Wirkung der Druckfeder an einen gegenüber dem Rahmen verschieblichen, die Rolle drehbar lagernden Schlitten angestellt. Das dem Spannschaft abgewandte Ende des genannten Hebels ist gelenkig mit einem unverdrehbaren Gewindebolzen verbunden, der mittels einer mit diesem zusammenarbeitenden am Widerlager abstützbaren Stellmutter unter Verkürzung der genannten Druckfeder in eine Öffnung des genannten Widerlagers hineinziehbar ist. Durch eine mit der Verkürzung der Druckfeder einhergehende Verdrehung des Spannschaftes nimmt dieser eine Drehstellung ein, in welcher die Rolle aus ihrer Arbeitslage in die hiervon abgerückte Lage verstellt ist. In dieser abgerückten Lage ist der endlose Riemen auf die Rolle aufziehbar bzw. von dieser abziehbar. Zu einem Wechsel des Riemens im Falle eines Verschleißes desselben bedarf es also eines Schraubvorganges, um die Spannung des abzuziehenden Riemens aufzuheben und eines weiteren Schraubvorganges, um einen neu aufgezogenen Riemen zu spannen.A belt drive of the type mentioned is for example from the document DE 197 12 690 A1. One herein for biasing the roll into its Working position disclosed spring arrangement is in one embodiment as Compression spring arrangement formed in which a compression spring between a hinged to a frame abutment and a lever is effective, the non-rotatable with a clamping shaft in the form of a rotatable in the frame mounted eccentric shaft is connected. An eccentric section of the Spannschaftes is under the action of the compression spring to a respect to the Sliding frame, the role rotatably mounted sled hired. The the clamping shaft facing away from the said lever is hinged with a non-rotatable threaded bolt connected by means of a with this cooperating on the abutment supportable adjusting nut under Shortening said compression spring in an opening of said Abutment is retractable. By one with the shortening of the compression spring accompanying rotation of the clamping shaft takes this one rotational position a, in which the role of their working position in the position withdrawn therefrom is displaced. In this withdrawn position is the endless belt on the roll removable or removable from this. To a change of the belt in the case a wear of the same so it requires a screwing to the Release the tension of the belt to be removed and another Screwing to tighten a newly wound belt.

Der Erfindung liegt die Aufgabe zugrunde, den eingangs genannten Riementrieb so auszugestalten, daß die Maßnahmen zum Wechseln eines Riemens vereinfacht werden und einen möglichst geringen Zeitaufwand erfordern.The invention is based on the object, the aforementioned Belt drive in such a way that the measures for changing a Belt are simplified and the least possible time require.

Zur Lösung dieser Aufgabe ist ein Zweischlag vorgesehen, mit dessen Hilfe die Rolle am Rahmen angelenkt ist, sowie ein Anschlag, der bei einer um ein bestimmtes Maß über eine Totpunktlage des Zweischlages hinaus erfolgenden Lageänderung des Zweischlags aus einer der Arbeitslage der Rolle entsprechenden Lage in eine der abgerückten Lage der Rolle entsprechenden Lage eine Lageveränderung des Zweischlages über das bestimmte Maß hinaus verhindert.To solve this problem, a two-stroke is provided with the help of the Roller is hinged to the frame, as well as a stop, the one at a certain degree taking place beyond a dead center of the two-layer Change in position of the double-layer from one of the working positions of the roll corresponding position in one of the withdrawn position of the role corresponding Location a change in position of the two-stroke over the certain dimension prevented.

Hiermit bedarf es zur Verlagerung der Rolle zwischen deren Arbeitslage und ihrer davon abgerückten Lage lediglich einer Schwenkung eines Armes des Zweischlages aus einer Lage des Armes diesseits einer Totpunktlage des Zweischlages in eine Lage jenseits dieser Totpunktlage und umgekehrt. Eine derartige Schwenkung ist gegenüber einem Schraubvorgang zum Spannen bzw. Entspannen des Riemens im Falle des obengenannten bekannten Riementriebes eine vergleichsweise einfache und relativ schnell durchführbare Maßnahme.This requires the relocation of the role between their work situation and her abrückten position only a swinging of an arm of the Two layers from a position of the arm on this side of a dead center of the Two shifts to a position beyond this dead center and vice versa. A such pivoting is compared to a screwing for clamping or relaxing the belt in the case of the above-known Belt drive a comparatively simple and relatively quickly feasible Measure.

Bei einer besonders vorteilhaften Ausgestaltung ist der Zweischlag mittels einer Exzentnerwelle und eines daran exzentrisch angelenkten Lenkers gebildet. Dies ermöglicht eine besonders einfache Einleitung einer Schwenkbewegung in einen Arm des Zweischlages, nämlich durch Verdrehen der Exzenterwelle um in jedem Falle weniger als eine volle Umdrehung.In a particularly advantageous embodiment of the two-layer by means of a Exzentnerwelle and an eccentrically articulated handlebar formed. This allows a particularly simple initiation of a pivoting movement in one arm of the two-blade, namely by turning the eccentric shaft to in any case less than a full turn.

In bevorzugter Weiterbildung dieser Ausgestaltung ist der Anschlag an der Exzenterwelle ausgebildet und in der der abgerückten Lage der Rolle entsprechenden Lage des Zweischlages am Lenker angeschlagen. Damit sind keine über den Zweischlag hinausgehenden Mittel erforderlich, um diesen unter der Wirkung der Federanordnung in seiner der abgerückten Lage der Rolle entsprechenden Lage zu arretieren.In a preferred embodiment of this embodiment, the stop on the Eccentric shaft formed and in the withdrawn position of the role corresponding position of the two-rail struck the handlebar. This is no means beyond the two-fold necessary to bring this under the effect of the spring arrangement in its withdrawn position of the roll appropriate position to lock.

Bei einem in Fig. 1 beispielhaft dargestellten Ausleger 1 ist der im weiteren Verlauf näher erläuterte Riementrieb mehrfach, und zwar senkrecht zur Figurenebene aufeinanderfolgend, zur Bildung einer Bogenbremse angeordnet.In a boom 1 exemplified in Fig. 1 is the further Course explained in more detail belt drive multiple, and perpendicular to Figure plane sequentially, arranged to form a sheet brake.

Der Ausleger folgt auf eine letzte Verarbeitungsstation einer Druckmaschine. Eine solche Verarbeitungsstation kann ein Druckwerk oder ein Nachbehandlungswerk sein, wie beispielsweise ein Lackwerk. Im vorliegenden Beispiel handelt es sich bei der letzten Verarbeitungsstation um ein im Offsetverfahren arbeitendes Druckwerk 2 mit einem Druckzylinder 2.1. Dieser führt flächige Bedruckstoffe in Form von Bogen 3 in einer mittels des Drehrichtungspfeiles 5 angedeuteten Verarbeitungsrichtung durch einen Druckspalt zwischen dem Druckzylinder 2.1 und einem damit zusammenarbeitenden Gummituchzylinder 2.2 und übergibt ihn anschließend an einen Kettenförderer 4 unter Öffnen von am Druckzylinder 2.1 angeordneten, zum Erfassen eines jeweiligen der Bogen 3 an einem Greiferrand am vorauseilenden Ende des Bogens vorgesehenen Greifern. Der Kettenförderer 4 umfasst zwei endlose Förderketten 6, von welchen eine jeweilige entlang einer jeweiligen Seitenwand des Kettenauslegers 1 betriebsmäßig umläuft. Eine jeweilige Förderkette 6 umschlingt je eines von zwei synchron angetriebenen Antriebskettenrädem 7, deren Drehachsen miteinander fluchten und ist im vorliegenden Beispiel über je ein gegenüber den Antriebskettenrädem 7 stromabwärts bezüglich der Verarbeitungsrichtung befindliches Umlenkkettenrad 8 geführt. Zwischen den beiden Förderketten 6 erstrecken sich von diesen getragene Greifersysteme 9 mit Greifern 9.1, welche Lücken zwischen den am Druckzylinder 2.1 angeordneten Greifern durchfahren und dabei einen jeweiligen Bogen 3 unter Erfassen des genannten Greiferrandes am vorauseilenden Ende des Bogens 3 unmittelbar vor dem Öffnen der am Druckzylinder 2.1 angeordneten Greifer übernehmen, ihn über eine Bogenleitvorrichtung 10 hinweg zu einer Bogenbremse 11 transportieren und sich dort zur Übergabe des Bogens 3 an die Bogenbremse 11 öffnen. Diese vermittelt den Bogen eine gegenüber der Verarbeitungsgeschwindigkeit verringerte Ablagegeschwindigkeit und gibt sie nach Erreichen derselben ihrerseits frei, so dass ein jeweiliger nunmehr verlangsamter Bogen 3 schließlich auf Vorderkantenanschläge 12 auftrifft und unter Ausrichtung an diesen und an diesen gegenüberliegenden Hinterkantenanschlägen 13 gemeinsam mit vorausgegangenen und/oder nachfolgenden Bogen 3 einen Stapel 14 bildet, der mittels eines Hubwerkes in dem Maße absenkbar ist, wie der Stapel 14 anwächst. Von dem Hubwerk sind in Fig. 1 lediglich eine den Stapel 14 tragende Plattform 15 und diese tragende, strichpunktiert angedeutete Hubketten 16 wiedergegeben.The boom follows a last processing station of a printing press. Such a processing station can be a printing unit or a Be after treatment plant, such as a coating plant. In the present For example, the last processing station is an im Offset method working printing unit 2 with a printing cylinder 2.1. This leads flat substrates in the form of sheet 3 in one by means of Direction of rotation arrow 5 indicated processing direction by a Pressure gap between the pressure cylinder 2.1 and a so cooperating blanket cylinder 2.2 and then passes it to a chain conveyor 4 under opening of the pressure cylinder 2.1 arranged to detect a respective one of the sheets 3 at one Gripper edge provided on the leading end of the sheet grippers. Of the Chain conveyor 4 comprises two endless conveyor chains 6, one of which respective ones along a respective side wall of the chain boom 1 rotates operationally. A respective conveyor chain 6 wraps around each one of two synchronously driven Antriebskettenrädem 7, whose axes of rotation are aligned with each other and is in the present example on each one opposite the drive sprocket 7 downstream with respect to the processing direction located Umlenkkettenrad 8 out. Between the two conveyor chains. 6 extend from these supported gripper systems 9 with grippers 9.1, which gaps between the arranged on the printing cylinder 2.1 grippers drive through it while a respective sheet 3 while detecting said Gripper edge at the leading end of the sheet 3 immediately before the Open the arranged on the printing cylinder 2.1 gripper take him over transport a sheet guiding device 10 to a sheet brake 11 and there open for the transfer of the sheet 3 to the sheet brake 11. This gives the bow one over the processing speed reduced filing speed and gives them after reaching the same in turn free, so that a respective now slowed bow 3 finally hits leading edge stops 12 and aligning these and at these opposite trailing edge stops 13th together with previous and / or subsequent sheets 3 a Stack 14 forms, which is lowered by means of a hoist to the extent that the stack 14 grows. From the hoist are in Fig. 1, only one Stack 14 bearing platform 15 and this bearing, dash-dotted indicated lifting chains 16 reproduced.

Die Förderketten 6 sind entlang ihrer Wege zwischen den Antriebskettenrädem 7 einerseits und den Umlenkkettenrädem 8 andererseits mittels hier nicht dargestellter Kettenführungsschienen geführt, welche somit die Kettenbahnen der Kettentrume bestimmen. Im vorliegenden Beispiel werden die Bogen 3 von dem in Fig. 1 unteren Kettentrum transportiert. Dem von diesem durchlaufenen Abschnitt der Kettenbahn folgt eine diesem zugewandte, an der Bogenleitvorrichtung 10 ausgebildete Bogenleitfläche 17. Zwischen dieser und dem jeweils darüber hinweggeführten Bogen 3 ist bevorzugt betriebsmäßig ein Tragluftpolster ausgebildet. Hierzu ist die Bogenleitvorrichtung 10 mit in die Bogenleitfläche 17 mündenden Blasluftdüsen ausgestattet, von welchen in Fig. 1 lediglich eine repräsentativ für deren Gesamtheit, und in symbolischer Darstellung in Form des Stutzens 18 wiedergegeben ist. The conveyor chains 6 are along their paths between the Antriebskettenrädem 7 on the one hand and the Umlenkkettenrädem 8 on the other guided by means not shown here chain guide rails, which thus determine the chain tracks of the chainline. In the present example the sheets 3 are transported by the lower in Fig. 1 chain center. the from this traversed section of the chain track follows this one facing, formed on the sheet guiding device 10 sheet guide surface 17th Between this and the respective transposed sheet 3 is preferably operationally designed a Tragluftpolster. For this is the Sheet guide 10 with opening into the sheet guide 17 Blasluftdüsen equipped, of which in Fig. 1 only one representative of their Entity, and in symbolic representation in the form of the neck 18 is reproduced.

Um ein gegenseitiges Verkleben der bedruckten Bogen 3 im Stapel 14 zu verhindern, sind auf dem Weg der Bogen 3 von den Antriebskettenrädem 7 zur Bogenbremse 11 ein Trockner 19 und eine Bestäubungsvorrichtung 20 vorgesehen.To a mutual bonding of the printed sheet 3 in the stack 14 to are on the way, the arc 3 of the Antriebskettenrädem 7 to Sheet brake 11, a dryer 19 and a dusting device 20th intended.

Zur Vermeidung einer übermäßigen Erwärmung der Bogenleitfläche 17 durch den Trockner 19 ist in die Bogenleitvorrichtung 10 ein Kühlmittelkreislauf integriert, der in Fig. 1 symbolisch durch einen Einlassstutzen 21 und einen Auslaßstutzen 22 an einer der Bogenleitfläche 17 zugeordneten Kühlmittelwanne 23 angedeutet ist.To avoid excessive heating of the sheet guide surface 17 by the dryer 19 is in the sheet guiding device 10, a coolant circuit integrated, in Fig. 1 symbolically by an inlet port 21 and a Outlet 22 associated with one of the sheet guide 17 Coolant trough 23 is indicated.

In Fig. 2 ist ein bevorzugtes Ausführungsbeispiel eines der die Bogenbremse 11 bildenden Riementriebe in einer Schnittdarstellung wiedergegeben, und zwar bei einem Schnittverlauf entlang der Linie II in Fig. 1, in welcher ein entsprechender Riementrieb lediglich stilisiert dargestellt ist.In Fig. 2 is a preferred embodiment of the one Sheet brake 11 forming belt drives in a sectional view reproduced, in a sectional view along the line II in Fig. 1, in which a corresponding belt drive is shown only stylized.

Gemäß Fig. 2 umfasst der Riementrieb einen Rahmen 24 mit zueinander parallelen Rahmenschenkeln 24.1, 24.2 und 24.3, von welchen der Rahmenschenkel 24.1 an einem freien Ende desselben zur Anbindung an den Ausleger 1 ausgebildet ist. In den Rahmenschenkeln 24.1 und 24.2 sind Führungsschlitze 25.1 und 25.2 vorgesehen. Diese nehmen einen Schlitten 26 entlang der Rahmenschenkel 24.1 und 24.2 längsverschieblich auf. Der Schlitten 26 trägt eine sich zwischen den Rahmenschenkel 24.1 und 24.2 erstreckende Achse 27, auf welcher eine Rolle 28 frei drehbar gelagert ist. Die Rahmenschenkel 24.1, 24.2 und 24.3 sind mittels eines Steges 29 miteinander verbunden.

In this working position of the roller 28 is the belt drive ready for use and driven by a drive shaft 35, which has a Belt drive 36 is in operative connection with the drive wheel 32.

Zwischen den Rahmenschenkeln 24.1 und 24.2 erstreckt sich eine in diesem gelagerte, parallel zur Achse 27 verlaufende Exzenterwelle 37. Diese besteht aus einem in Fig. 5 dargestellten kreiszylindrischen Grundkörper 37.1, der in dessen Längsrichtung von einem exzentrisch angeordneten, in den Figuren 3a und 3b im Querschnitt erkennbaren Stift 37.2 durchsetzt ist und derart tiefe Abflachungen 37.1' aufweist, dass diese über deren jeweilige Erstreckung in der genannten Längsrichtung den Stift 37.2 freilegen. Ein Lenker 38 ist einerseits in einem jeweiligen durch die Abflachung 37.1' freigelegten Abschnitt des Stiftes 37.2 gelenkig mit diesem und andererseits gelenkig mit dem Schlitten 26 verbunden. Der Lenker 38 und die aus dem Grundkörper 37.1 und dem Stift 37.2 gebildete Exzenterwelle 37 bilden somit einen ersten und einen zweiten Arm eines Zweischlages 37, 38, mittels welchem der Schlitten 26 und damit die Rolle 28 an dem Rahmen 24 angelenkt ist. Bei diesem Art der Anlenkung der Rolle 28 an den Rahmen 24 ist die Rolle 28 unter einer bei einer Drehung der Exzenterwelle 37 erfolgenden Lageänderung des Zweischlages 37, 38 auf unterschiedliche Achsabstände zur Rolle 31 einstellbar.Between the frame legs 24.1 and 24.2 extends one in this mounted, parallel to the axis 27 extending eccentric shaft 37. This consists from a circular-cylindrical basic body 37. 1 shown in FIG the longitudinal direction of which is arranged eccentrically, in the figures 3a and 3b recognizable in cross-section pin 37.2 is interspersed and so deep Flattening 37.1 'has that over their respective extent in expose the pin 37.2 of said longitudinal direction. A handlebar 38 is on the one hand in a respective section exposed by the flattening 37.1 ' of the pin 37.2 articulated with this and on the other hand articulated with the Carriage 26 connected. The handlebar 38 and the body 37.1 and formed the pin 37.2 eccentric shaft 37 thus form a first and a second arm of a two-bladed 37, 38, by means of which the carriage 26 and so that the roller 28 is hinged to the frame 24. In this type of Linkage of the roller 28 to the frame 24, the roller 28 under a at a Rotation of the eccentric shaft 37 taking place change in position of the Two-layer 37, 38 at different center distances to the roller 31st adjustable.

Zur Einleitung einer Drehbewegung in die Exzenterwelle 37 ist im vorliegenden Beispiel an einer Stirnseite derselben ein Innensechskant 37.1" vorgesehen, so dass die Exzenterwelle 37 mittels eines in den Innensechskant eingesetzten Imbusschlüssels verdrehbar ist.To initiate a rotational movement in the eccentric shaft 37 is in the present Example on a front side of the same a hexagon socket 37.1 "provided so that the eccentric shaft 37 is inserted by means of a hexagon socket Allen key is rotatable.

In den Figuren 2 und 3a ist der Riementrieb im gespannten Zustand des Riemens 33 dargestellt. Der sich hierbei einstellende Achsabstand ergibt sich aus der Länge und den Werkstoffeigenschaften des Riemens 33 und der von den Druckfedern 34 auf den Schlitten 26 ausgeübten Druckkraft. Der Zweischlag 37, 38 ist so ausgelegt, dass sich dessen Arme im gespannten Zustand des Riemens 33 vor einer durch eine gestreckte Lage der Arme definierten Totpunktlage befinden. Zur Erreichung einer von der Arbeitslage der Rolle 28 abgerückten Lage derselben, in welcher der Riemen 33 ungespannt ist, wird der mittels der Exzenterwelle 37 gebildete Arm des Zweischlages 37, 38 derart zunächst entgegen der Wirkung der Druckfedern 34 gedreht, dass die Arme des Zweischlages 37, 38 bis zur Erreichung einer zweiten Totpunktlage zusammenklappen. Nach Überschreitung dieser Totpunktlage bewirken sodann die Druckfedern 34 eine weitere Drehung der Exzenterwelle 37 um ein derart durch einen im weiteren Verlauf erläuterten Anschlag festgelegtes Maß, dass sich der Achsabstand der Rolle 28 zur Rolle 31 bei dieser weiteren Drehung der Exzenterwelle 37 um weniger vergrößert als er sich bis zum Erreichen der nunmehr überschrittenen Totpunktlage des Zweischlages 37, 38 verkleinert hat. Bei Erreichen der durch den Anschlag festgelegten Lage des Zweischlages 37, 38 befindet sich somit die Rolle 28 in einer von ihrer Arbeitslage abgerückten Lage, in welcher der Riemen 33 ungespannt ist. In Fig. 3b ist die dabei von dem Zweischlag 37, 38 eingenommene Lage dargestellt.In Figures 2 and 3a, the belt drive in the tensioned state of Belt 33 shown. The resulting axis spacing results from the length and the material properties of the belt 33 and of the compression springs 34 on the carriage 26 exerted pressure force. Of the Zweiischlag 37, 38 is designed so that its arms are stretched Condition of the belt 33 in front of a stretched position of the arms defined dead center are located. To achieve a work situation of the Roll 28 pulled-off position of the same, in which the belt 33 unstressed is, is formed by the eccentric shaft 37 arm of the two-blade 37, 38 so initially against the action of the compression springs 34 rotated that the Arms of the two-layer 37, 38 until reaching a second dead center fold. After exceeding this dead center then cause the compression springs 34 a further rotation of the eccentric shaft 37 to such a determined by a stop explained below, that the axial distance of the roller 28 to the roller 31 in this further rotation the eccentric shaft 37 increased by less than it reaches until reaching the now exceeded dead center of the two-layer 37, 38 reduced Has. Upon reaching the position determined by the stop the two-bladed 37, 38 is thus the role 28 in one of their working position detached position in which the belt 33 is unstressed. In Fig. 3b is the in the process taken by the two-layer 37, 38 assumed position.

Unter der Wirkung der gegen den Anschlag arbeitenden Druckfeder 34 behält der Zweischlag 37, 38 auch seine Lage bei, die der von der Arbeitslage abgerückten Lage der Rolle 28 entspricht.Retains under the action of the compression spring 34 working against the stop the two-stroke 37, 38 also at its location, that of the working position pulled-off position of the roller 28 corresponds.
