Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, den Bereitstellungsaufwand zur Durchführung von mit druckmittelbetriebenen Austreibvorrichtungen durchführbaren Arbeiten zu reduzieren.The present invention is based on the object to reduce the deployment effort to carry out feasible with fluid-powered Austreibvorrichtungen work.
Zur Lösung dieser Aufgabe weist die erfindungsgemäße Austreibvorrichtung die Merkmale des Anspruchs 1 auf.To solve this problem, the Austreibvorrichtung invention has the features of claim 1.
Erfindungsgemäß wird somit eine Austreibvorrichtung vorgeschlagen, die je nach Arbeits- oder Einsatzbedingungen sowohl ein Netzbetrieb, also einen an eine stationäre Druckquelle angeschlossenen Betrieb, als auch eine netzunabhängigen Betrieb, also einen Betrieb basierend auf dem durch den Druckmittelspeicher definierten Druckluftreservoir, ermöglicht.According to the invention, therefore, an expulsion device is proposed which, depending on the working or operating conditions, enables both a network operation, ie an operation connected to a stationary pressure source, and a network-independent operation, ie an operation based on the compressed air reservoir defined by the pressure medium reservoir.
Die erfindungsgemäße Austreibvorrichtung weist die Druckanschlussvorrichtung mit einer Druckminderereinrichtung auf die sowohl vom Druckmittelspeicher als auch von der stationären Druckquelle her mit Druck beaufschlagbar ist. Hierdurch kann bei voreingestelltem Arbeitsdruck zum Betrieb der Austreibvorrichtung beliebig zwischen dem Anschluss an die stationäre Druckquelle oder den Druckmittelspeicher gewählt werden, ohne eine einmal an die Arbeitsbedingungen angepasste Einstellung des Arbeitsdrucks ändern zu müssen.The expulsion device according to the invention has the pressure connection device with a pressure reducing device which can be acted upon by pressure from both the accumulator and the stationary pressure source. As a result, can be selected at a preset working pressure to operate the expelling device arbitrarily between the connection to the stationary pressure source or the pressure medium storage without having to change once adjusted to the working conditions adjustment of the working pressure.
Erfindungsgemäß ist in der Druckverbindung zwischen der Druckminderereinrichtung und dem Druckmittelspeicher eine weitere Druckminderereinrichtung angeordnet, so dass sichergestellt werden kann, dass bei einem Wechsel zwischen dem Druckspeicherdruck und dem Netzdruck zum Betrieb der Austreibvorrichtung keine schädlichen Druckspitzen auftreten.According to the invention, a further pressure reducing device is arranged in the pressure connection between the pressure reducing device and the pressure medium reservoir, so that it can be ensured that no detrimental pressure peaks occur when changing between the pressure accumulator pressure and the network pressure for operating the expelling device.
Wenn die Druckminderereinrichtung an eine Druckkammer angeschlossen ist, die über einen ersten Druckanschluss mit dem Druckmittelspeicher und einen zweiten Druckanschluss mit der stationären Druckquelle verbindbar ist, ist sichergestellt, dass sowohl der durch das Druckluftre- servoir des Druckmittelspeicher generierte Speicherdruck als auch der durch die stationäre Druckquelle generierte Netzdruck in gleicher Weise auf die Druckminderereinrichtung wirken.If the pressure reducer device is connected to a pressure chamber which can be connected to the pressure medium reservoir via a first pressure port and to the stationary pressure source via a second pressure port, it is ensured that both the reservoir pressure generated by the compressed air reservoir of the pressure fluid reservoir and that generated by the stationary pressure source Generated network pressure act in the same way on the pressure reducer.
Als besonders vorteilhaft erweist es sich, wenn die Druckanschlussvorrichtung einen Geräteanschlusskörper und einen Speicheranschlusskörper aufweist, die über eine Druckleitung miteinander verbunden sind, wobei der Geräteanschlusskörper zum Anschluss an die Austreibvorrichtung und der Speicheranschlusskörper zum Anschluss an den Druckmittelspeicher dient. Hierdurch ist es möglich, zur Ausbildung der Druckanschlussvorrichtung separate Anschlusseinheiten vorzusehen, die örtlich unabhängig voneinander in den jeweils günstigsten Positionen an der Austreibvorrichtung angeordnet werden können.It proves to be particularly advantageous if the pressure connection device has a device connection body and a memory connection body which are connected to one another via a pressure line, wherein the device connection body serves for connection to the expelling device and the storage connection body for connection to the pressure medium reservoir. This makes it possible to provide for the formation of the pressure connection device separate connection units, which can be arranged locally independently of each other in the most favorable positions on the expulsion device.
Wenn darüber hinaus der Geräteanschlusskörper zur Anordnung eines Druckanschlusses für die stationäre Druckquelle und zur Anordnung der ersten Druckminderereinrichtung dient, und der Speicheranschlusskörper zu Anordnung eines Druckanschlusses für den Druckmittelspeicher und zur Anordnung der zweiten Druckminderereinrichtung dient, ist eine unmittelbare Zuordnung der Druckminderereinrichtungen zu den mit ihnen zusammenwirkenden Einrichtungen der Austreibvorrichtung möglich, sodass etwa Bedienungsfehler der Austreibvorrichtung durch ein Verwechseln der Druckminderereinrichtungen auszuschließen sind.In addition, when the device connector body is for arranging a pressure port for the stationary pressure source and for disposing the first pressure reducer, and the memory port body is for disposing a pressure port for the pressure fluid reservoir and for disposing the second pressure reducer, then the pressure reducers are directly associated with those cooperating with them Facilities of Austreibvorrichtung possible, so about operator errors of Austreibvorrichtung be excluded by confusing the pressure reducer devices.
Wenn der Speicheranschlusskörper als Tragkonsole zur Aufnahme des Druckmittelspeichers ausgebildet ist, erfüllt der Speicheranschlusskörper gleichzeitig die Funktion einer mechanischen Kupplungseinrichtung zur Verbindung des Druckmittelspeichers mit der Austreibvorrichtung.If the storage connection body is designed as a support bracket for receiving the accumulator, the accumulator body simultaneously fulfills the function of a mechanical coupling device for connecting the accumulator with the Austreibvorrichtung.
Wenn der Speicheranschlusskörper darüber hinaus an einer mit einem Gerätekörper der Austreibvorrichtung verbundenen Magazinvorrichtung angeordnet ist, kann der Gerätekörper der Austreibvorrichtung selbst identisch gestaltet sein mit einem Gerätekörper einer Austreibvorrichtung, die ausschließlich zum Anschluss an eine stationäre Druckluftquelle bestimmt ist.In addition, when the storage port body is disposed on a magazine device connected to an apparatus body of the expelling device, the apparatus body of the expelling device itself may be identically configured with an apparatus body of an expelling device exclusively for connection to a stationary compressed air source.
Als besonders vorteilhaft hinsichtlich der Handhabung der Austreibvorrichtung erweist es sich, wenn der Speicheranschlusskörper derart an der Magazinvorrichtung angeordnet ist, dass sich der Druckmittelspeicher längs der Magazinvorrichtung erstreckt, sodass das Bauvolumen der mit einem Druckmittelspeicher versehenen Austreibvorrichtung sich im Wesentlichen nicht von dem Bauvolumen einer ausschließlich für den Anschluss an eine stationäre Druckluftquelle bestimmten Austreibvorrichtung unterscheidet.It proves to be particularly advantageous with regard to the handling of the expulsion device, when the storage connection body is arranged on the magazine device such that the pressure medium accumulator extends along the magazine device, so that the construction volume of the expelling device provided with a pressure medium accumulator essentially does not depend on the construction volume of exclusively for distinguishes the connection to a stationary compressed air source certain expelling device.
Als besonders vorteilhaft wirkt es sich auch auf die Betriebssicherheit der Austreibvorrichtung aus, wenn sich der Druckmittelspeicher zumindest mit einem Teilbereich durch eine mit der Magazinvorrichtung verbundene Protektoreinrichtung erstreckt, sodass der Druckmittelspeicher vor äußeren Beschädigungen geschützt ist. Darüber hinaus kann je nach Ausbildung der Protektoreinrichtung diese auch zur statischen Abstützung des Druckmittelspeichers beitragen.It also has a particularly advantageous effect on the operational safety of the expelling device when the pressure medium reservoir is at least partially connected to the magazine device connected protector device extends so that the accumulator is protected from external damage. In addition, depending on the design of the protector device, these also contribute to the static support of the accumulator.
Als besonders einfach in der Ausgestaltung sowie auch besonders effektiv in ihrer Wirkung erweist sich eine Protektoreinrichtung, die durch eine sich peripher zum Querschnittsumfang erstreckende Bügeleinrichtung gebildet ist.A protector device that is formed by an ironing device extending peripherally to the cross-sectional circumference proves to be particularly simple in design and also particularly effective in its effect.
Nachfolgend wird eine bevorzugte Ausführungsform der Austreibvorrichtung anhand der Zeichnung näher erläutert.Hereinafter, a preferred embodiment of the expelling device will be explained with reference to the drawing.
