Description

Die Erfindung betrifft eine druckmittelbetriebene Austreibvorrichtung zum Austreiben von Gegenständen oder fluiden Stoffen aus einem Reservoir mittels eines druckmittelbeaufschlagtem Treibkolbens mit einem über eine Druckanschlussvorrichtung austauschbar mit der Austreibvorrichtung verbundenen Druckmittelspeicher zur Druckmittelbeaufschlagung des Treibkolbensgemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fluid-driven expulsion device for expelling objects or fluids from a reservoir by means of a pressure medium-loaded drive piston with a via a pressure connection device interchangeable with the Austreibvorrichtung connected accumulator for Druckmittelbeaufschlagung the drive piston according to the preamble of claim 1.

Eine Vorrichtung der eingangs genannten Art in der Ausführung als Schlaggerät zum Eintreiben mechanischer Befestigungsmittel, wie beispielsweise Stahlstifte, ist aus der WO 03/002308 A1 bekannt. Bei der bekannten Vorrichtung ist der Druckmittelspeicher unmittelbar an einen Gerätekörper der Austreibvorrichtung angeschlossen. Der Druckmittelspeicher ermöglicht einen netzunabhängigen Betrieb der Austreibvorrichtung, sodass die Austreibvorrichtung zu ihrem Betrieb nicht an eine stationäre Druckquelle angeschlossen werden muss. Dies ermöglicht insbesondere in den Fällen, in denen häufige Positionswechsel mit der Austreibvorrichtung vorzunehmen sind, eine erheblich vereinfachte Handhabung der Austreibvorrichtung. In anderen Einsatzfällen, in denen der Betrieb der Austreibvorrichtung überwiegend in unveränderter Position erfolgt oder die mechanischen Befestigungsmittel nur unter sehr hohem Kraftaufwand eintreibbar sind, kann es sich jedoch auch als vorteilhaft erweisen, eine Austreibvorrichtung zu verwenden, die an eine stationäre Druckluftquelle angeschlossen ist, da in diesen Fällen das i begrenzte Volumen eines Druckmittelspeichers nur eine entsprechend kurze Betriebszeit der Austreibvorrichtung ermöglichen würde.A device of the type mentioned in the execution as impact device for driving mechanical fasteners, such as steel pins, is from the WO 03/002308 A1 known. In the known device, the accumulator is connected directly to a device body of Austreibvorrichtung. The accumulator allows a network-independent operation of the expulsion device, so that the Austreibvorrichtung must not be connected to a stationary pressure source for their operation. This makes possible a considerably simplified handling of the expelling device, in particular in cases where frequent changes of position are to be made with the expelling device. In other applications where However, it may also be advantageous to use a Austreibvorrichtung, which is connected to a stationary source of compressed air, since limited in these cases, the i the operation of Austreibvorrichtung predominantly in the same position or mechanical fasteners can be driven only under very high force Volume of a pressure medium reservoir would allow only a correspondingly short operating time of the expulsion device.

Um je nach Einsatzbedingungen die jeweils günstigeren Arbeitsbedingungen für den Anwender zu ermöglichen, ist es bislang notwendig zwischen einer mit einem Druckmittelspeicher versehenen Austreibvorrichtung und einer zum Anschluss an eine stationäre Druckluftquelle geeigneten Austreibvorrichtung zu wählen, sodass zumindest zwei entsprechend unterschiedlich ausgebildete Austreibvorrichtungen mit den damit verbundenen, entsprechend hohen Anschaffungskosten bereitzustellen sind.In order to enable the user in each case more favorable working conditions depending on the conditions of use, it has heretofore been necessary to choose between an expulsion device provided with a pressure fluid accumulator and an expelling device suitable for connection to a stationary compressed air source, so that at least two suitably differently configured expelling devices are connected to the associated expulsion devices. are to be provided according to high acquisition costs.

Aus der US-B1-6 220 496 ist eine druckmittelbetriebene Austreibvorrichtung zum Austreiben von Gegenständen aus einem Reservoir mittels eines druckmittelbeaufschlagten Treibkolbens bekannt, bei der ein über eine Druckanschlussvorrichtung austauschbar mit der Austreibvorrichtung verbundener Druckmittelspeicher zur Druckmittelbeaufschlagung des Treibkolbens vorgesehen ist. Die Druckanschlussvorrichtung dient sowohl zum Anschluss des Druckmittelspeichers als auch zum Anschluss an eine stationäre Druckquelle.From the US-B1-6 220 496 is a pressure medium driven expelling device for expelling objects from a reservoir by means of a pressure medium-loaded driving piston, in which a via a pressure connection device interchangeable with the Austreibvorrichtung connected pressure medium accumulator is provided for pressure medium loading of the driving piston. The pressure connection device serves both for connection of the pressure medium reservoir and for connection to a stationary pressure source.

Die DE 36 22 687 A1 zeigt einen pneumatisch betriebenen Schlagschrauber mit einem Antriebsmotor für ein Schlagwerk, der einen über eine im Gehäuse verlaufende Luftleitung an den Antriebsmotor angeschlossenen Druckluftbehälter aufweist.The DE 36 22 687 A1 shows a pneumatically operated impact wrench with a drive motor for a striking mechanism, which has a connected via an air line extending in the housing to the drive motor compressed air tank.

Die FR-A-2 651 299 zeigt einen Druckmittelspeicher, der zum Betrieb eines mit Luftdruck betriebenen Werkzeuges direkt an den Druckluftanschluss des Werkzeuges anschließbar ist.The FR-A-2 651 299 shows a pressure fluid store, which is connected to operate a tool operated with air pressure directly to the compressed air connection of the tool.

Aus der DE 37 30 049 A1 ist ein druckmittelbetriebenes Schlaggerät für Heftmittel bekannt, das mit einem austauschbaren Druckbehälter versehen ist.From the DE 37 30 049 A1 is known a pressure medium-operated striker for stapling, which is provided with a replaceable pressure vessel.

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.

Die Beaufschlagung des Austreibbolzens 26 wird über eine Betätigung eines am Gerätekörper 11 angeordneten Abzugshebels 21 ausgelöst.For pressure medium supply is in the in Fig. 1 illustrated embodiment of the device connection body 15 a here designed as a connecting piece pressure port 20 is provided which serves for connection to a stationary compressed air source, so for example a compressor device, via a power cord not shown here. About the pressure port 20, a Austreibbolzen 26 of the driving piston unit 12 of the expelling device 10 by means of a, not shown here, the pressure port 20 through the device connector body 15 and the device body 11 with the driving piston unit 12 connecting pressure line means are subjected to working pressure. The loading of the Austreibbolzens 26 is triggered by an actuation of a arranged on the device body 11 trigger lever 21.

Der an der Magazinvorrichtung 13 angeordnete Speicheranschlusskörper 16 ist über einen Druckanschluss 22 mit einem Druckmittelspeicher 23 verbunden, der im vorliegenden Fall Druckluft mit einem Speicherdruck von etwa 300 bar enthält. Über den Druckanschluss 22, den Speicheranschlusskörper 16 und die Druckleitung 17 besteht eine Druckverbindung zwischen dem im Druckmittelspeicher 23 aufgenommenen Druckluftreservoir und dem Geräteanschlusskörper 15, der, wie vorstehend ausgeführt, über eine Druckverbindung mit der Treibkolbeneinheit 12 verbunden ist.The arranged on the magazine device 13 storage connector body 16 is connected via a pressure port 22 with a pressure medium reservoir 23, which in the present case contains compressed air with a storage pressure of about 300 bar. Via the pressure connection 22, the accumulator connection body 16 and the pressure line 17 there is a pressure connection between the compressed air reservoir received in the accumulator 23 and the device connection body 15, which, as stated above, is connected via a pressure connection with the driving piston unit 12.

Die Magazinvorrichtung 13 weist in einem hier lediglich strichpunktiert angedeuteten Gehäusekanal 36 des Magazingehäuses 19 angeordnet eine in einem Reihenverbund angeordnete Anzahl von Stahlstiften 24 auf, die mit ihrer Längsachse jeweils parallel zur Achse eines Austreibkanals 25 angeordnet sind und über eine in der Magazinvorrichtung 13 angeordnete, hier nicht näher dargestellte axiale Vortriebseinrichtung in eine Schlussposition im Austreibkanal 25 gezwungen werden. Bei anstehendem Arbeitsdruck erfolgt durch eine Betätigung des Abzugshebels 21 eine Beaufschlagung der Stahlstifte 24 durch den Austreibbolzen 26 der Treibkolbeneinheit 12, sodass der Stahlstift 24 aus dem Austreibkanal 25 herausgetrieben wird.The magazine device 13 has arranged in a dash-dotted line here housing channel 36 of the magazine housing 19 arranged in a series combination number of steel pins 24, which are each arranged with its longitudinal axis parallel to the axis of Austreibkanals 25 and arranged in the magazine device 13, here axial propulsion device not shown are forced into a final position in the drive channel 25. With pending working pressure is effected by actuation of the trigger lever 21, an action on the steel pins 24 through the Austreibbolzen 26 of the driving piston unit 12, so that the steel pin 24 is driven out of the drive channel 25.

Wie insbesondere Fig. 1 zeigt, ist der Geräteanschlusskörper 15 flanschartig mit dem freien Ende des Handgriffteils 18 verbunden und weist hierzu, wie Figur 5 zeigt, drei Befestigungsbohrungen 27 auf, die zur Durchführung nicht näher dargestellter Befestigungsschrauben dienen. Wie weiter aus einer Zusammenschau der Figuren 1, 4 und 5 deutlich wird, weist der Geräteanschlusskörper 15 neben dem Druckanschluss 20, der zur Verbindung mit einer stationären Druckluftquelle dient, einen Druckanschluss 28 auf, der über die damit verbundene Druckleitung 17 zum Anschluss des Druckmittelspeichers 23 an den Geräteanschlusskörper 15 dient. Der Druckanschluss 20 und der Druckanschluss 28 sind über eine im Geräteanschlusskörper 15 angeordnete Ventileinrichtung 29 miteinander verbunden, die je nach Schaltstellung ihres Ventilelements 30 eine Druckluftverbindung zwischen dem Druckanschluss 28 und einer zur Treibkolbeneinheit 12 der Austreibvorrichtung 10 führenden Arbeitsdruckkanal 31 oder dem Druckanschluss 20 und der Arbeitsdruckkanal 31 ermöglicht. Der Arbeitsdruckkanal 31 mündet in der Darstellung gemäß Figur 5 in einen Ventilraum 32, in dem das Ventilelement 30 zwischen zwei Schaltstellungen bewegbar ist. An einem in der Darstellung gemäß Fig. 5 hinter der Ventileinrichtung 29 angeordneten Druckraum 33 ist eine in Figur 1 dargestellte Druckminderereinrichtung 34 angeschlossen. In den Druckraum 33 mündet schließlich ein Arbeitsdruckkanal 35, der sich durch den Handgriffteil 18 bis hin zur Treibkolbeneinheit 12 zur Beaufschlagung des Austreibbolzens 26 mit Arbeitsdruck fortsetzt.In particular Fig. 1 shows, the device connector body 15 is flange-connected to the free end of the handle portion 18 and has for this purpose, as FIG. 5 shows, three mounting holes 27, which serve to perform unspecified mounting screws. How further from a synopsis of FIGS. 1, 4 and 5 becomes clear, the device connection body 15, in addition to the pressure port 20, which serves for connection to a stationary compressed air source, a pressure port 28 which serves via the pressure line connected thereto 17 for connection of the pressure medium reservoir 23 to the device connection body 15. The pressure port 20 and the pressure port 28 are connected to each other via a device arranged in the device body 15 valve means 29, depending on the switching position of its valve member 30, a compressed air connection between the pressure port 28 and a drive piston unit 12 of the expelling 10 leading working pressure channel 31 or the pressure port 20 and the working pressure channel 31 allows. The working pressure channel 31 opens in the illustration according to FIG. 5 in a valve chamber 32, in which the valve element 30 is movable between two switching positions. At one in the presentation according to Fig. 5 behind the valve means 29 arranged pressure chamber 33 is an in FIG. 1 shown pressure reducer 34 connected. In the pressure chamber 33 finally opens a working pressure channel 35, which continues through the handle portion 18 to the driving piston unit 12 for acting on the Austreibbolzens 26 with working pressure.

Der Ventilraum 32 ist in einer Gehäusebohrung 37 des Geräteanschlusskörpers 15 ausgebildet, die nach außen hin durch einen Bohrungsstopfen 38 verschlossen ist. In der Gehäusebohrung 37 ist ein hülsenförmig ausgebildetes Ventilsitzelement 40 angeordnet, das durch eine zwischen dem Bohrungsstopfen 38 und dem Ventilsitzelement 40 angeordnete Abstandshülse 39 zur Positionierung gegen einen Bohrungsabsatz 41 gedrückt wird. Auf der gegenüberliegenden Seite des Ventilraums 32 ist ein weiterer Bohrungsabsatz ausgebildet, der als Gehäuseventilsitz 42 dient. Die Schaltstellungen des Ventilelements 30 sind also einerseits durch Anlage des Ventilelements gegen das Ventilsitzteil 39 und andererseits durch Anlage des Ventilelements gegen den Gehäuseventilsitz 42 definiert. In der in Fig. 5 dargestellten Ausführungsform weist das Ventilelement einen zylinderstiftartig ausgebildeten Ventilkörper mit einer radial darauf angeordneten Ventildichtung 44 auf. Zur Fluidverbindung zwischen dem Druckanschluss 20 und dem Ventilraum 32 ist die Hülse mit Wandungsbohrungen 45 versehen, die eine Fluidverbindung mit dem Druckanschluss 20 ermöglichen.The valve chamber 32 is formed in a housing bore 37 of the device connection body 15, which is closed to the outside by a bore plug 38. In the housing bore 37, a sleeve-shaped valve seat member 40 is arranged, which is pressed by a disposed between the bore plug 38 and the valve seat member 40 spacer sleeve 39 for positioning against a bore 41. On the opposite side of the valve chamber 32, a further bore paragraph is formed, which serves as a housing valve seat 42. The switching positions of the valve element 30 are therefore defined on the one hand by contact of the valve element against the valve seat part 39 and on the other hand by abutment of the valve element against the housing valve seat 42. In the in Fig. 5 In the embodiment shown, the valve element has a valve body formed in the manner of a cylinder pin with a valve seal 44 arranged radially thereon. For fluid communication between the pressure port 20 and the valve space 32, the sleeve is provided with wall bores 45 which allow fluid communication with the pressure port 20.

Zur eindeutigen Definition einer bestimmten Schaltstellung im Fall einer Druckbeaufschlagung des Druckanschlusses 20 und des Druckanschlusses 28 ist der über den Druckanschluss 28 vom Druckmittelspeicher 23 mittel einer, wie in Fig. 6 dargestellt, im Speicheranschlusskörper 16 angeordneten Druckminderereinrichtung 46 grundsätzlich höher eingestellt, als der von der stationären Druckluftquelle über den Druckanschluss 20 auf das Ventilelement 30 wirkende Ventildruck. Beispielsweise kann der am Druckanschluss 28 anliegende Druck auf 15 bar eingestellt sein, der somit höher ist als der üblicherweise auf 8 bar eingestellte Druck einer stationären Druckluftquelle.For a clear definition of a particular switching position in the case of pressurization of the pressure port 20 and the pressure port 28 of the pressure port 28 from the accumulator 23 means one, as in Fig. 6 shown, arranged in the accumulator body 16 pressure reducer 46 is generally set higher than the force acting from the stationary compressed air source via the pressure port 20 to the valve element 30 valve pressure. For example, the pressure applied to the pressure port 28 can be set to 15 bar be, which is thus higher than the usually set to 8 bar pressure of a stationary compressed air source.

Wie eine Zusammenschau der Fig. 3, 4 und 6 zeigt, ist der an dem Magazingehäuse 19 der Magazinvorrichtung 13 angeordnete Speicheranschlusskörper 16 neben der Druckminderereinrichtung 46, die in Fluidverbindung zwischen dem Druckanschluss 22 und einem Anschlussstutzen 48 für die Druckleitung 17 angeordnet ist, mit einem Sicherheitsventil 49 zur Unterbrechung einer Druckverbindung zwischen dem Druckmittelspeicher 23 und der Druckminderereinrichtung 46 versehen. Außerdem ist der Speicheranschlusskörper 16 im vorliegendem Fall noch einen Füllstandsanzeiger 50 zur Anzeige des aktuell im Druckmittelspeicher 23 enthaltenen Volumens versehen.Like a synopsis of Fig. 3, 4 and 6 shows, which is arranged on the magazine housing 19 of the magazine device 13 storage connector body 16 adjacent to the pressure reducer 46, which is arranged in fluid communication between the pressure port 22 and a connecting piece 48 for the pressure line 17, with a safety valve 49 to interrupt a pressure connection between the accumulator 23 and the pressure reducer 46 provided. In addition, the storage connection body 16 is provided in the present case, a level indicator 50 for displaying the volume currently contained in the pressure medium accumulator 23.

Der in Fig. 5 dargestellte Geräteanschlusskörper 15 ermöglicht vermittels der Ventileinrichtung 29 sowohl einen gleichzeitigen Anschluss des Druckmittelspeichers 23 an den Druckanschluss 28 und einer stationären Druckluftquelle an den Druckanschluss 20, wobei durch den vermittels der Druckminderereinrichtung 46 vergleichsweise höher einstellbaren, durch den Druckmittelspeicher 23 bewirkten Ventildruck in diesem Fall eindeutig eine Druckversorgung der Treibkolbeneinheit 12 über den Druckmittelspeicher 23 definiert ist. Darüber hinaus ist es natürlich möglich, nur den Druckanschluss 20 oder den Druckanschluss 28 mit Druck zu beaufschlagen.The in Fig. 5 shown device connection body 15 allows by means of the valve means 29 both a simultaneous connection of the pressure medium reservoir 23 to the pressure port 28 and a stationary compressed air source to the pressure port 20, wherein by the means of the pressure reducing means 46 comparatively higher adjustable, caused by the pressure medium accumulator 23 valve pressure in this case clearly one Pressure supply of the driving piston unit 12 is defined via the accumulator 23. In addition, it is of course possible to pressurize only the pressure port 20 or the pressure port 28.

Wie insbesondere aus den Fig. 1 und 2 ersichtlich, ist der Druckmittelspeicher 23 mit seinem Anschlussende 51 so mit dem Druckanschluss 22 des Speicheranschlusskörpers 16 verbunden, dass er sich längs der Magazinvorrichtung 13 erstreckt. Dabei dient der Speicheranschlusskörper 16, der auf nicht näher dargestellte Art und Weise starr mit dem Magazingehäuse 19 der Magazinvorrichtung 13 verbunden ist, auch als Tragkonsole, die im Wesentlichen die mechanische Abstützung des Druckmittelspeichers 23 übernimmt. Ebenfalls am Magazingehäuse 19 angeordnet, befindet sich eine Protektoreinrichtung 52, die einen Aufnahmering 53 aufweist, in den der Druckmittelspeicher 23 mit seinem Zylinderkörper 54 eingeführt ist. Je nach gewählter Passung zwischen dem Innendurchmesser des Aufnahmerings 53 und dem Außendurchmesser des Zylinderkörpers 54 kann der Aufnahmering 53 den Druckmittelspeicher 23 ergänzend zum Speicheranschlusskörper 16 abstützen oder lediglich einen Schutzring um den Zylinderkörper 54 bilden, der den Druckmittelspeicher 23 vor Stößen, etwa verursacht durch ein Ablegen der Austreibvorrichtung 10 auf einer Ablagefläche schützt. Bei der in Figur 1 dargestellten Anordnung des Druckmittelspeichers 23 an der Magazinvorrichtung 13 kommt auch dem Magazingehäuse 19 eine ergänzende Protektorfunktion zu, da der Druckmittelspeicher 23 innerhalb der Breitenerstreckung des Magazingehäuses 19 angeordnet ist.As in particular from the Fig. 1 and 2 can be seen, the pressure fluid reservoir 23 is connected with its terminal end 51 to the pressure port 22 of the storage port body 16 so that it extends along the magazine device 13. In this case, the storage connection body 16, which is connected in a manner not shown rigidly with the magazine housing 19 of the magazine device 13, as a support bracket, which essentially takes over the mechanical support of the accumulator 23. Also arranged on the magazine housing 19, there is a protector device 52 which has a receiving ring 53, in which the pressure medium accumulator 23 is introduced with its cylinder body 54. Depending on the selected fit between the inner diameter of the receiving ring 53 and the outer diameter of the cylinder body 54, the receiving ring 53 may support the accumulator 23 complementary to the storage port body 16 or merely form a guard ring around the cylinder body 54, the accumulator 23 from shocks, such as caused by a drop protects the expelling device 10 on a shelf. At the in FIG. 1 shown arrangement of the accumulator 23 to the magazine device 13 is also the magazine housing 19 a complementary protector function, since the accumulator 23 is disposed within the width of the magazine housing 19.
