Description

[Beschreibung][Description]

Die Erfindung betrifft einen Antrieb für eine Druckmaschine gemäß dem Oberbegriff von Anspruch 1.The invention relates to a drive for a printing press according to the preamble of claim 1.

[Stand der Technik][State of the art]

Eine Vielzahl von Druckmaschinen und insbesondere Bogenoffsetdruckmaschinen weisen an den Druckwerkszylindern sowie den Bedruckstofftransport beteiligten Zylindern (Transfertrommeln, Wendetrommeln, Speichertrommeln) Zahnräder auf, die paarweise miteinander in Verbindung stehen. Der Antrieb eines so gebildeten Räderzuges erfolgt an ein oder mehreren Stellen über Zwischenräder und Elektromotore. Wichtig für einen registerhaltigen und doublierfreien Druck ist, dass die Zahnflanken der Zahnräder des Räderzuges gleichbleibend aneinander anliegen, d.h. dass keine durch das Spiel im Räderzug bedingten Zahnflankenwechsel auftreten. Dies kann insbesondere durch das Einspeisen einer Antriebsleistung an mehreren Stellen des Räderzuges erfolgen, wobei der Anteil des eingespeisten Antriebsmomentes genau auf die vorliegenden Bedingungen des Räderzuges abgestimmt ist. Nachteilig bei derartigen Antrieben ist jedoch, dass mehrere Elektromotore zu verwenden sind, was gerade bei kleineren Druckmaschinen einen großen Kostennachteil darstellt.A variety of printing machines and especially sheetfed offset printing machines point to the printing unit cylinders as well as the Cylinders involved in printing material transport (transfer drums, Turning drums, storage drums) gears on that communicate in pairs. The drive of one wheel train thus formed takes place at one or more points via idler gears and electric motors. Important for one Register and duplication-free printing is that the The tooth flanks of the gear wheels of the gear train remain the same abut each other, i.e. that none through the game in Gear flank-related tooth flank changes occur. This can in particular by feeding in a drive power several points of the gear train take place, the share of the input drive torque exactly to the present Conditions of the gear train is matched. A disadvantage of such drives, however, is that multiple electric motors are to be used, which is particularly the case with smaller printing machines represents a major cost disadvantage.

Aus der DE 296 09 962 A1 ist eine Vorrichtung zur Vermeidung eines Flankenwechsels zwischen Zähnen von Antriebsrädern einer Druckmaschine bekannt, bei welcher dem angetriebenen Zylinder ein ein Bremsmoment erzeugendes Klemmelement zugeordnet ist. Das durch das Klemmelement erzeugte Bremsmoment kann dabei einstellbar sein.DE 296 09 962 A1 describes a device for avoidance a flank change between teeth of drive wheels known a printing press, in which the driven Cylinder assigned a clamping element generating a braking torque is. The braking torque generated by the clamping element can be adjustable.

Durch eine derartige Vorrichtung ergibt sich eine einseitige Verspannung des Räderzuges dahingehend, dass die Antriebsräder stets gleichbleibend an den gleichen Flanken anliegen. Nachteilig ist hierbei jedoch, dass die Vorrichtung einen bestimmten Bauaufwand darstellt und ferner auch die durch das dauernde Bremsmoment erzeugte Reibungswärme abgeführt werden muss.Such a device results in one-sided Bracing the gear train in such a way that the drive wheels always lie on the same flanks. The disadvantage here, however, is that the device has a represents certain construction costs and also by the permanent braking torque generated friction heat are dissipated got to.

Aus der DE 42 28 506 A1 ist ein Antrieb für eine Druckmaschine mit mehreren Druckwerken und einem gemeinsamen Räderzug bekannt, bei welcher durch einen ersten Antriebsmotor in den Räderzug ein Leistungsüberschuss eingespeist wird und durch einen letzten Antriebsmotor dieser Leitungsüberschuss wieder abgeführt wird. Der letzte Antriebsmotor fungiert somit als Bremse.DE 42 28 506 A1 describes a drive for a printing press with several printing units and a common gear train known in which by a first drive motor in the Excess power is fed in and through a last drive motor this line surplus again is dissipated. The last drive motor thus acts as Brake.

Nachteilig bei dieser Antriebslösung ist, dass mehrere, zumindest aber wenigstens zwei Antriebsmotore vorzusehen sind, die durch eine entsprechende Steuerung in der vorgesehenen Weise zu betreiben sind. Gerade bei kleinen Druckmaschinen ist eine derartige Lösung nicht kostengünstig.The disadvantage of this drive solution is that several but at least provide at least two drive motors are provided by an appropriate control in the Way to operate. Especially with small printing machines such a solution is not inexpensive.

Aus der DE 37 10 354 A1 sowie der DE 32 00 064 A1 sind hydraulische Einrichtungen umfassende Antriebe für Mehrfarben-Bogenrotationsdruckmaschinen bekannt. Hier werden über einen Hydrogenerator ein oder mehrere Hydromotoren angetrieben, die ihrerseits Leistung in den Räderzug einspeisen. Eine derartige Lösung ist wegen der Hydrogeneratoren und Hydromotoren aufwendig und ferner auch nicht ohne weiteres bei schnelllaufenden Druckmaschinen verwendbar. Auch diese Lösung ist bei kleinen Bogendruckmaschinen nicht wirtschaftlich einsetzbar.DE 37 10 354 A1 and DE 32 00 064 A1 are hydraulic Facilities comprehensive drives for multi-color sheet-fed rotary printing presses known. Here are about one Hydrogenerator powered one or more hydraulic motors that in turn feed power into the gear train. Such Solution is because of the hydrogenerators and hydraulic motors complex and also not easily with high-speed Printing machines can be used. This solution is also included small sheet printing machines cannot be used economically.

[Aufgabe der Erfindung]OBJECT OF THE INVENTION

Aufgabe der vorliegenden Erfindung ist es daher, einen Antrieb für eine Druckmaschine gemäß dem Oberbegriff von Anspruch 1 derartig zu erweitern, so dass unter Vermeidung der zuvorstehend genannten Nachteile ein Flankenwechsel zwischen den Zähnen der Antriebsräder vermieden wird. The object of the present invention is therefore a drive for a printing press according to the preamble of claim 1 to expand so that while avoiding the Disadvantages mentioned above, an edge change between the teeth of the drive wheels is avoided.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale von Anspruch 1. Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.This task is solved by the characteristic features of claim 1. Developments of the invention result from the subclaims.

[Beispiele][Examples]

Nach der Erfindung ist vorgesehen, dass dem Antrieb wenigstens eine hydraulische Bremse zugeordnet ist, durch welche die an einer oder mehreren Stellen in den Räderzug eingespeiste Antriebsleistung kompensiert wird.According to the invention it is provided that the drive at least a hydraulic brake is assigned by which that are fed into the gear train at one or more points Drive power is compensated.

Gemäß einem bevorzugten Ausführungsbeispiel der Erfindung ist dabei vorgesehen, dass die hydraulische Bremse als eine über ein mit einem Zahnrad des Räderzuges in Verbindung stehendes Ritzel angetriebene Hydraulikpumpe ausgebildet ist. Das von der Hydraulikpumpe in einem Kreislauf geförderte Öl wird dabei bevorzugt über eine einstellbare Drossel gefördert, so dass das durch die Pumpe in den Antriebsräderzug rückgeführte Bremsmoment einstellbar ist. Die Hydraulikpumpe ist bevorzugt als Zahnradpumpe ausgebildet.According to a preferred embodiment of the invention thereby envisaged that the hydraulic brake as one over one related to a gear train of the gear train Pinion driven hydraulic pump is formed. That from the hydraulic pump is pumped oil in a circuit preferably promoted via an adjustable throttle, so that the pump returns to the drive gear train Braking torque is adjustable. The hydraulic pump is preferred designed as a gear pump.

Gemäß einer bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, dass als Hydraulikflüssigkeit das der Schmierung der Druckmaschine dienende Öl verwendet wird, welches über einen Auffangbehälter unter der Druckmaschine aufgenommen, gefiltert, durch die vom Räderzug angetriebene Pumpe, von dort über die einstellbare Drossel und wieder zurück in den Auffangbehälter des Schmieröles gefördert wird. Dabei kann insbesondere auch vorgesehen sein, mit dem durch die Pumpe geförderten Öl bestimmte Schmierstellen an der Maschine zu versorgen.According to a preferred embodiment of the invention be provided that as the hydraulic fluid Oil used to lubricate the printing press which over a collecting container under the printing machine recorded, filtered, by the driven by the gear train Pump, from there via the adjustable throttle and again is pumped back into the oil tank.

Gemäß einer Weiterbildung der Erfindung ist vorgesehen, den durch die Pumpe und die Drossel auf den Räderzug bewirkten Widerstand in Abhängigkeit von der Maschinendrehzahl zu gestalten. Hierzu wäre es möglich, die Einstellung der Drossel mit der Maschinendrehzahl zu ändern, bspw. um bei niedrigen Geschwindigkeiten einen höheren Druck und somit eine höhere Bremswirkung zu erzielen als bei hohen Maschinengeschwindigkeiten. Dieser Effekt kann in einer einfachen Ausgestaltung auch durch ein zwischen Pumpe und Drossel geschaltetes Überdruckventil erfolgen. Ab einer bestimmten Maschinendrehzahl lässt das Überdruckventil Öl ab, d.h. der durch die Pumpe erzeugte Öldruck und somit auch das Bremsmoment reduzieren sich bzw. nehmen nicht mehr mit der Geschwindigkeit zu.According to a development of the invention, the caused by the pump and the throttle on the gear train Resistance depending on the machine speed too shape. For this it would be possible to adjust the throttle to change with the machine speed, for example, at low Speeds a higher pressure and thus a to achieve a higher braking effect than at high machine speeds. This effect can be done in a simple embodiment also by a switch connected between the pump and the throttle Pressure relief valve. Above a certain machine speed the pressure relief valve drains oil, i.e. the by the pump generates oil pressure and therefore also the braking torque decrease or no longer increase with speed to.
