Abstract
Description
Die Erfindung betrifft eine Anlage zum kontrollierten Ausbringen eines Schmiermittels aus einer zylinderförmigen Schmiermittelkartusche, mit einem Auspresskolben, der zum Ausbringen des Schmiermittels in die Kartusche eintaucht und Druck auf das Schmiermittel ausübt.The invention relates to a system for the controlled discharge of a lubricant from a cylindrical lubricant cartridge, with a squeezing piston, which dips into the cartridge for applying the lubricant and exerts pressure on the lubricant.
Schmiermittel werden, neben den gängigen Gebindegrößen, zunehmend auch in handlichen, genormten Eurokartuschen angeboten. Der Einsatz dieser 400 ml fassenden Kartuschen als Schmiermittelspeicher ist insbesondere dort von Vorteil, wo nur geringe Schmiermittelaufträge zu realisieren sind, und ein einfaches Handling gefragt ist. Das Überschreiten maximaler Verarbeitungszeiträume bei der Verwendung größerer Gebinde sowie zeitaufwendige Gebindewechsel können damit vermieden werden.Lubricants are, in addition to the usual container sizes, increasingly available in handy, standardized euro cartridges. The use of these 400 ml cartridges as a lubricant reservoir is particularly advantageous where only small amounts of lubricant can be produced, and easy handling is required. Exceeding maximum processing periods when using larger containers and time-consuming container changes can be avoided.
Zum Ausbringen des Schmiermittels aus diesen Kartuschen werden bislang vorwiegend handbettigte Geräte eingesetzt. Diese auch als Fettpressen bezeichneten Geräte sind je nach Viskosität des verwendeten Schmiermittels kraftaufwändig zu bedienen, und die mit ihnen ausgebrachte Menge an Schmiermittel ist nur sehr ungenügend zu kontrollieren.To dispense the lubricant from these cartridges so far mainly hand-operated devices are used. These devices, also referred to as grease guns, can be operated with great force, depending on the viscosity of the lubricant used, and the amount of lubricant applied with them can only be checked very insufficiently.
Weiterhin sind auch motorisch betriebene Fettpressen bekannt, bei denen zumindest die Handhabung gegenüber den zuvor genannten Handgeräten vereinfacht ist.Furthermore, motor-driven grease presses are known in which at least the handling over the aforementioned hand-held devices is simplified.
So offenbart etwa die Gebrauchsmusterschrift
Ein kontrolliertes Ausbringen des Schmiermittels insbesondere im Hinblick auf einen kontinuierlichen und mengenmäßig reproduzierbaren Schmiermittelfluss ist auch mit dieser Anlage nicht gewährleistet.A controlled spreading of the lubricant, in particular with regard to a continuous and quantitatively reproducible lubricant flow is not guaranteed even with this system.
Die vorliegende Erfindung stellt dagegen eine speziell für die automatische und prozesssichere Entleerung von Schmiermittelkartuschen entwickelte Anlage dar, die sich gleichermaßen für den Einsatz an Handarbeitsplätzen wie in automatisierten Montageanlagen zur Schmiermittelversorgung eignet.By contrast, the present invention represents a system specially developed for the automatic and process-reliable emptying of lubricant cartridges, which is equally suitable for use on manual workstations as in automated assembly systems for supplying lubricant.
Dies wird erfindungsgemäß dadurch erreicht, dass der Auspresskolben mit einer Durchtrittsöffnung versehen ist, die mit einem Kolbenrohr verbunden ist, durch das das Schmiermittel zu einer Auslassöffnung der Anlage geleitet wird.This is inventively achieved in that the extrusion piston is provided with a passage opening which is connected to a piston tube through which the lubricant is passed to an outlet opening of the system.
Diese erfindungsgemäße Ausführung ermöglicht es, die Schmiermittelkartusche an der dem Auspresskolben abgewandten Seite verschlossen zu lassen, und den auf das Schmiermittel ausgeübten Druck durch Steuerung der Kraft, mit der sich Schmiermittelkartusche und Auspresskolben aufeinander zu bewegen, zu kontrollieren.This embodiment of the invention makes it possible to leave the lubricant cartridge closed on the side facing away from the squeezing piston, and to control the pressure exerted on the lubricant by controlling the force with which the lubricant cartridge and squeezing piston move towards each other.
Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Anlage ist die Kartusche in ein aus Edelstahl gefertigtes Führungsrohr gesetzt, das während der automatischen Entleerung als Führung für den Auspresskolben dient und zudem die Formstabilität der Kartusche gewährleistet.In a preferred embodiment of the system according to the invention, the cartridge is placed in a guide tube made of stainless steel, which serves as a guide for the extrusion piston during the automatic emptying and also ensures the dimensional stability of the cartridge.
Bei einer bevorzugten Weiterbildung der erfindungsgemäßen Anlage ist vorgesehen, dass zur Verbesserung der Entlüftung der Kartusche der Auspresskolben an seiner Unterseite im wesentlichen als ein flacher mit seiner Spitze nach unten weisender Kegel geformt und mit einer zusätzlichen dünnen Bohrung versehen ist, die mit einer Leitung zur Entlüftung der Kartusche verbunden ist.In a preferred embodiment of the system according to the invention it is provided that is formed to improve the venting of the cartridge of the extrusion piston on its underside substantially as a flat with its tip downwardly facing cone and is provided with an additional thin bore, with a line for venting the cartridge is connected.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Anlage ergeben sich aus den Unteransprüchen und werden anhand der Zeichnung erläutert.Further advantageous embodiments and modifications of the system according to the invention will become apparent from the dependent claims and will be explained with reference to the drawing.
