Abstract
Description
Die Erfindung betrifft eine Sicherheitseinrichtung, insbesondere bei Umkleidungen von Werkzeugmaschinen, nach dem Oberbegriff des Anspruches 1.The The invention relates to a safety device, in particular in Covers of machine tools, according to the preamble of the claim 1.
Es ist bekannt, daß Werkzeugmaschinen von Umkleidungen umgeben sind. An die Umkleidung ist ein Absaugrohr angeschlossen, über das ständig während der Bearbeitung von Werkstücken auf der Werkzeugmaschine Luft abgesaugt wird. Sie enthält Kühlschmierstoff-Nebel, der sich aus dem bei der Werkstückbearbeitung zugeführten Kühlschmierstoff bildet. Dieses Gemisch aus Luft und Kühlschmierstoff-Nebel wird mittels einer Absauganlage aus dem Innenraum der Umkleidung ständig abgesaugt. Im Bereich von verschließbaren Öffnungen in der Umkleidung, beispielsweise im Bereich von Türen, Beladeluken und dgl., können diese Nebel nach außen treten.It It is known that machine tools of Envelopes are surrounded. To the casing is a suction tube connected, over that constantly while the machining of workpieces the machine tool is sucked air. It contains coolant lubricant mist, resulting from the workpiece machining supplied coolant forms. This mixture of air and coolant mist is using an extraction system from the interior of the enclosure constantly sucked. In the area of closable openings in the enclosure, for example in the area of doors, Beladeluken and the like., Can these mists to the outside to step.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Sicherheitseinrichtung so auszubilden, daß bei einfacher und kostengünstiger Ausbildung zuverlässig der Austritt von schädlichen Medien verhindert.Of the Invention is based on the object, the generic safety device so that at easier and cheaper Training reliable the escape of harmful Media prevented.
Diese Aufgabe wird bei der gattungsgemäßen Sicherheitseinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.These Task is in the generic safety device according to the invention with the characterizing Characteristics of claim 1 solved.
Mit der erfindungsgemäßen Sicherheitseinrichtung wird im Bereich der Durchtrittsstelle für das Medium die Luftsperre erzeugt, die einen Austritt bzw. Zutritt des Mediums zuverlässig verhindert. Diese Sperre wird durch die abgesaugte Luft selbst erzeugt. Darum ist keine aufwendige und damit kostenintensive Bereitstellung eines zusätzlichen Mediums für die Luftsperre notwendig.With the safety device according to the invention becomes the air barrier in the area of the passage for the medium generated, which reliably prevents leakage or access of the medium. This barrier is generated by the extracted air itself. Therefore is not a complicated and thus costly provision of a additional Medium for the air barrier is necessary.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further Features of the invention will become apparent from the other claims, the Description and the drawings.
Die Erfindung wird anhand eines in den Zeichnungen dargestellten Ausführungsbeispieles näher erläutert. Es zeigenThe The invention will be explained in more detail with reference to an embodiment shown in the drawings. It demonstrate
Die Sicherheitseinrichtung dient dazu, den Austritt von Emissionen, insbesondere von Kühlschmierstoff-Emulsionen aus Umkleidungen von Werkzeugmaschinen, zu unterbinden. Solche Werkzeugmaschinen-Umkleidungen haben Türen, Beladeluken, Absaugstellen und dgl., die potentielle undichte Stellen der Umkleidung bilden. Über sie kann beispielsweise ein Kühlschmierstoffnebel austreten und zu einer Verschmutzung des Umgebungsbereiches der Umkleidung führen.The Safety device serves to control the emission of emissions, in particular of cooling lubricant emulsions from claddings of machine tools, to prevent. Such machine tool coatings have doors, Beladeluken, suction points and the like., The potential leaks form the casing. about For example, it can be a cooling lubricant mist leak out and lead to pollution of the surrounding area of the Lead the casing.
