Description

Die Erfindung betrifft eine pneumatische Anordnung mit mehreren Wartungsmodulen zur Druckluftaufbereitung, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a pneumatic arrangement with several Maintenance modules for compressed air treatment, according to the Preamble of claim 1.

Eine derartige Anordnung zur Druckluftaufbereitung ist beispielsweise aus der EP 0909898 A1 bekannt. Bei jedem pneumatischen System ist eine derartige Druckluftaufbereitungsanordnung erforderlich, um den Druck und den Ölgehalt einzustellen und die von der Druckluftquelle kommende Druckluft zu filtern. Nahezu alle pneumatischen Aktoren, wie Zylinder, Greifer, Antriebe und Stellglieder, benötigen für den Betrieb Ventile zur Steuerung der Zu- und Abfuhr von Druckluft oder Vakuum. Derartige Ventile sind in bekannter Weise zu Ventilanordnungen zusammengefasst, wobei jeder aus mehreren Ventilen bestehenden Ventilanordnung eine elektronische Steuervorrichtung zugeordnet ist, die meistens ihrerseits über eine Feldbusleitung an eine Steuerzentrale angeschlossen ist.Such an arrangement for compressed air treatment, for example known from EP 0909898 A1. At every pneumatic System is such a compressed air treatment arrangement required to adjust the pressure and oil content and the coming of the compressed air source of compressed air filter. Almost all pneumatic actuators, such as cylinders, Grippers, drives and actuators, required for operation Valves for controlling the supply and removal of compressed air or Vacuum. Such valves are in a known manner to valve arrangements summarized, each consisting of several valves existing valve assembly, an electronic control device is assigned, usually in turn on a Fieldbus line is connected to a control center.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, kostengünstigere pneumatische Anordnungen bei Verringerung der Zahl der Steuergeräte bzw. Steuermodule zu schaffen.Based on this prior art, the invention the task is based, more cost-effective pneumatic arrangements when reducing the number of control units or control modules to accomplish.

Diese Aufgabe wird erfindungsgemäß durch eine pneumatische Anordnung mit den Merkmalen des Anspruchs 1 gelöst. This object is achieved by a pneumatic Arrangement solved with the features of claim 1.

Vorteilhafterweise wird dadurch nur ein einziges Steuermodul für die Druckluftaufbereitung und die Ventilsteuerung benötigt, wobei insgesamt eine kompakte Baueinheit ohne freiliegende Verbindungsleitungen geschaffen wird. Dabei bleibt die Variabilität erhalten, da an das gemeinsame Bussystem beliebige weitere Wartungsmodule oder Ventile angeschlossen werden können, die jeweils insgesamt die kompakte Baueinheit bilden.Advantageously, thereby only a single control module needed for compressed air preparation and valve control, where a total of a compact unit without exposed Connecting lines is created. The remains Variability obtained as to the common bus system arbitrary additional maintenance modules or valves are connected can each form the overall compact unit.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen pneumatischen Anordnung möglich.By the measures listed in the dependent claims are advantageous developments and improvements in the claim 1 specified pneumatic arrangement possible.

Die Ventile und die Wartungsmodule sind zweckmäßigerweise nebeneinander am gemeinsamen Bussystem angeordnet und bilden auf diese Weise die Baueinheit. Diese Anordnung erleichtert das Anbringen zusätzlicher oder das Entfernen vorhandener Ventile und Wartungsmodule.The valves and the maintenance modules are expediently next to each other arranged and form the common bus system in this way the unit. This arrangement facilitates installing additional or removing existing ones Valves and maintenance modules.

Weiterhin wird eine besonders große Variabilität dadurch erreicht, dass das Bussystem als Busleitungsleiste ausgebildet ist, die vorzugsweise aus einzelnen aneinandersteckbaren Leistenelementen besteht, wobei die Module und die Ventilanordnung an dieser Busleitungsleiste aneinanderreihbar sind. Auch bei einer Änderung der mechanischen Reihenfolge der Module und Ventilanordnung oder bei einer Erweiterung durch weitere Module kann die Busleitung durch einfaches Umstecken angepasst werden, ohne dass irgendwelche Fehlverbindungen möglich wären. Insbesondere bei einzelnen aneinandersteckbaren Leistenelementen ist eine einfache Längenanpassung an die Modul- und Ventilanordnungsreihe möglich. Die Busleitungsleiste kann sogar die mechanische Verbindung der Module und Ventilanordnung gewährleisten oder zumindest zu dieser beitragen. Furthermore, a particularly large variability is achieved by that the bus system is designed as a bus bar is, preferably from individual abutting bar elements consists, the modules and the valve assembly can be lined up at this Busleitungsleiste. Also when changing the mechanical order of the modules and valve assembly or at an extension by others Modules can be adapted to the bus line by simply repositioning be possible without any misconnections would. Especially with individual abutting bar elements is a simple length adjustment to the module and valve arrangement series possible. The busbar can even the mechanical connection of the modules and valve assembly ensure or at least contribute to this.

Das Steuermodul kann in einem der Wartungsmodule integriert oder als separates Modul am Bussystem oder an der Ventilanordung angeordnet sein. Es wird zweckmäßigerweise zwischen der Ventilanordnung und den Wartungsmodulen angeordnet.The control module can be integrated in one of the maintenance modules or as a separate module on the bus system or on the valve arrangement be arranged. It is expediently between the Valve assembly and arranged the maintenance modules.

Zur pneumatischen Verbindung zwischen den Wartungsmodulen und der Ventilanordnung ist zweckmäßigerweise ein pneumatisches Adaptermodul dazwischen am Bussystem angeordnet. Dieses kann auch noch zur elektrischen Adaption dienen, falls erforderlich.For pneumatic connection between the maintenance modules and the valve assembly is suitably a pneumatic Adapter module arranged between the bus system. This can also serve for electrical adaptation, if necessary.

Das Steuermodul besitzt in vorteilhafter Weise eine Feldbusschnittstelle für ein externes Bussystem, damit das Steuermodul mit einer externen Steuerzentrale verbunden werden kann. Diese externe Steuerzentrale kann Funktionen des Steuermoduls beeinflussen bzw. verändern oder auch direkt auf die Wartungsmodule bzw. die Ventilanordnung zugreifen. Andererseits kann das Steuermodul auch eine eigene Intelligenz besitzen, sodass im Normalbetrieb eine Verbindung mit der Steuerzentrale nicht erforderlich sein wird.The control module advantageously has a fieldbus interface for an external bus system, hence the control module can be connected to an external control center. This external control center can be functions of the control module influence or change or directly on the maintenance modules or access the valve assembly. on the other hand the control module can also have its own intelligence, so in normal operation, connect to the control center will not be required.

Zur Veränderung von Einstellungen vor Ort ist zweckmäßigerweise eine Anzeige- und/oder Bedieneinheit im Steuermodul integriert oder als separate Einheit an das Steuermodul angeschlossen ist, insbesondere über Ethernet, oder mit diesem drahtlos in Wirkverbindung steht.To change settings on site is expediently a display and / or operating unit integrated in the control module or connected as a separate unit to the control module is, especially via ethernet, or with this wirelessly in operative connection.

Die Wartungsmodule und/oder die Ventile der Ventilanordnung sind wenigstens teilweise mit Sensoren und/oder Diagnosemitteln versehen, insbesondere Drucksensoren, deren Sensorsignale über das Bussystem an das Steuermodul übertragbar sind. Dies ermöglicht zum einen eine Überwachung durch das Steuermodul und zum anderen die parameterabhängige Steuerung und Einstellung der Wartungsmodule und der Ventilanordnung durch das Steuermodul.The maintenance modules and / or the valves of the valve arrangement are at least partially with sensors and / or diagnostic means provided, in particular pressure sensors whose sensor signals be transferable via the bus system to the control module.
