Description

Die Erfindung betrifft eine pneumatische Anordnung mit mehreren Wartungsmodulen zur Druckluftaufbereitung, die an einem gemeinsamen Bussystem nebeneinander angeordnet sind, und mit einem an das Bussystem angeschlossenen Steuermodul zur Ausführung von Steuer- und/oder Überwachungsfunktionen und/oder Kommunikationsfunktionen für die Wartungsmodule.The invention relates to a pneumatic arrangement with several Maintenance modules for compressed air preparation that work on one common bus system are arranged side by side, and with a control module connected to the bus system for execution of control and / or monitoring functions and / or Communication functions for the maintenance modules.

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 preparation is, for example known from EP 0909898 A1. Any pneumatic System is such a compressed air treatment arrangement required to adjust the pressure and oil content and the compressed air coming from the compressed air source filter. Almost all pneumatic actuators, such as cylinders, Grippers, drives and actuators are required for operation Valves for controlling the supply and discharge 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, most of which in turn have 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.The invention is based on this prior art based on the task of cheaper pneumatic arrangements when reducing the number of control units or control modules to accomplish.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an das gemeinsame Bussystem auch eine Ventilanordnung angeschlossen ist, wobei das Steuermodul auch zur Ausführung von Steuer- und/oder Überwachungsfunktionen für die Ventile der Ventilanordnung ausgebildet ist und die Ventilanordnung zusammen mit den Wartungsmodulen eine Baueinheit bildet.This object is achieved in that the common bus system also connected a valve arrangement is, the control module also for executing Control and / or monitoring functions for the valves of the Valve arrangement is formed and the valve arrangement together forms a structural unit with the maintenance modules.

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.This advantageously means that only a single control module required for compressed air treatment and valve control, overall a compact unit with no exposed Connection lines is created. The remains Maintain variability, since any of the common bus system additional maintenance modules or valves can be connected can, which together form the 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 subclaims 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 advantageously next to each other arranged and form on the common bus system this way the assembly. This arrangement facilitates adding 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 that the bus system is designed as a bus line strip is preferably made of individual pluggable There are strip elements, the modules and the valve arrangement can be strung together on this bus line strip. Even if the mechanical order of the modules changes and valve arrangement or in the case of an expansion the bus cable can be plugged in further modules be adjusted without any wrong connections would be possible. Especially with individual pluggable Last elements is a simple length adjustment to the Module and valve arrangement series possible. The bus line bar can even the mechanical connection of the modules and Ensure valve arrangement 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 conveniently between the Valve arrangement and the maintenance modules arranged.

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 the pneumatic connection between the maintenance modules and the valve arrangement is expediently a pneumatic one Adapter module arranged in between on 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 so that the control module can be connected to an external control center.
