Description

Die Erfindung betrifft ein Auspreßwerkzeug der im Ober­begriff des Patentanspruchs 1 angegebenen Art.The invention relates to an extrusion tool of the type specified in the preamble of claim 1.

Pastöse Dichtungsmassen, Kleber u.dgl. werden in Kar­tuschen geliefert, die einen zylindrischen Kartuschen­körper aufweisen, an dessen vorderem Ende ein Auslaß­stutzen vorgesehen ist. Das rückwärtige Ende des Kar­tuschenkörpers ist offen und darin befindet sich ein Kolben, der vorgetrieben werden kann, um den Inhalt aus dem vorderen Kartuschenende herauszupressen. Zum Vor­schieben des Kolbens wird ein Auspreßwerkzeug benutzt, das entweder einen mechanischen Vorschubmechanismus für einen gegen den Kolben drückenden Auspreßschieber hat oder pneumatisch betrieben ist.Pasty sealants, adhesives and the like are supplied in cartridges that have a cylindrical cartridge body, at the front end of which an outlet nozzle is provided. The rear end of the cartridge body is open and inside is a plunger that can be propelled to force the contents out of the front end of the cartridge. An extrusion tool is used to advance the piston, which either has a mechanical feed mechanism for an extrusion slide pressing against the piston or is pneumatically operated.

EP 0 092 607 B1 beschreibt ein pistolenförmiges Aus­preßwerkzeug, das einen rohrförmigen Kartuschenhalter aufweist, in den die Kartusche von vorne eingesetzt werden kann. Am vorderen Ende des Kartuschenhalters befinden sich elastische Arme mit nach innen gerichte­ten Vorsprüngen. Die Kartusche kann von vorne her in den Kartuschenhalter eingesetzt werden, wobei die Arme auseinanderfedern. Wenn die Kartusche eingesetzt ist, rasten die Vorsprünge der Arme am vorderen Kartuschen­ende ein. Diese Raststellung wird durch eine auf dem Kartuschenhalter sitzende Schiebehülse verriegelt. Auf diese Weise ist ein einfaches Auswechseln der Kartusche möglich, ohne daß Schraubvorgänge durchgeführt werden müssen. Nachteilig ist allerdings, daß ein derartiges Auspreßwerkzeug generell nur für eine bestimmte Kar­tuschenlänge geeignet ist und daß für unterschiedliche Kartuschenlängen in der Regel unterschiedliche Auspreß­werkzeuge benötigt werden. Ferner wird die Länge des Auspreßwerkzeugs wesentlich durch die Länge des Kar­tuschenhalters bestimmt, so daß das Auspreßwerkzeug viel Platz und eine großvolumige Verpackung erfordert.EP 0 092 607 B1 describes a pistol-shaped extrusion tool which has a tubular cartridge holder into which the cartridge can be inserted from the front. At the front end of the cartridge holder there are elastic arms with inward projections. The cartridge can be inserted into the cartridge holder from the front, with the arms springing apart. When the cartridge is inserted, the projections of the arms snap into place at the front end of the cartridge. This locking position is locked by a sliding sleeve on the cartridge holder. In this way, the cartridge can be easily replaced without screwing operations having to be carried out. However, it is disadvantageous that such an extrusion tool is generally only suitable for a certain cartridge length and that it is suitable for different ones Cartridge lengths usually require different extrusion tools. Furthermore, the length of the extrusion tool is largely determined by the length of the cartridge holder, so that the extrusion tool requires a lot of space and a large-volume packaging.

Der Erfindung liegt die Aufgabe zugrunde, ein Auspreß­werkzeug der im Oberbegriff des Patentanspruchs 1 ange­gebenen Art zu schaffen, das für unterschiedliche Kar­tuschenlängen geeignet ist und platzsparend gelagert und verpackt werden kann.The invention has for its object to provide an extrusion tool of the type specified in the preamble of claim 1, which is suitable for different cartridge lengths and can be stored and packaged to save space.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs 1 ange­gebenen Merkmalen.This object is achieved according to the invention with the features specified in the characterizing part of patent claim 1.

Bei dem erfindungsgemäßen Auspreßwerkzeug ist der Kar­tuschenhalter mit einem Schnellverschluß am Gehäuse befestigt, so daß er vom Gehäuse gelöst werden kann. Das Laden des Kartuschenhalters mit der Kartusche er­folgt vom offenen rückwärtigen Ende her und die Kar­tusche stützt sich an einer festen Schulter des Kar­tuschenhalters entgegen der Richtung, in der die Aus­preßkraft wirkt, ab. Ein wesentlicher Vorteil besteht darin, daß für unterschiedliche Kartuschengrößen und Kartuschenformen unterschiedliche Kartuschenhalter be­reitgehalten werden können, die mit dem Gehäuse ver­bunden werden. Das Gehäuse der Auspreßvorrichtung kann somit wahlweise mit einem von mehreren Kartuschen­haltern benutzt werden. Der Kartuschenhalter ist ein relativ einfach und kostengünstig herzustellendes Teil, während das Gehäuse, das entweder den Antriebsmechanis­mus oder ein betätigbares Ventil für die Druckluft­zufuhr enthält, relativ aufwendig ist.In the extrusion tool according to the invention, the cartridge holder is fastened to the housing with a quick-release fastener so that it can be detached from the housing. The cartridge holder is loaded with the cartridge from the open rear end and the cartridge is supported on a firm shoulder of the cartridge holder against the direction in which the ejection force acts. A major advantage is that different cartridge holders can be kept ready for different cartridge sizes and cartridge shapes, which are connected to the housing. The housing of the squeezing device can thus be used optionally with one of several cartridge holders. The cartridge holder is a relatively simple and inexpensive part to manufacture, while the housing, which contains either the drive mechanism or an actuatable valve for the compressed air supply, is relatively complex.

Für den Schnellverschluß sind verschiedene Varianten möglich, beispielsweise eine Ausführungsform, bei der der Kartuschenhalterzur Betätigung des Verschlusses relativ zum Gehäuse gedreht werden muß, oder auch eine Ausführungsform mit Schiebehülse.Various variants of the quick-release fastener are possible, for example an embodiment in which the cartridge holder has to be rotated relative to the housing in order to actuate the fastener, or an embodiment with a sliding sleeve.

Gemäß einer bevorzugten Ausbildung der Erfindung ist entweder der Kartuschenhalter oder die Kartusche rela­tiv zum Gehäuse drehbar. Dabei kann der Kartuschen­auslaß an schwer zugänglichen Stellen in einer ge­wünschten Weise an das Werkstück angesetzt werden, während es möglich ist, das Gehäuse so zu drehen, daß der von Hand zu bedienende Betätigungshebel in der für den Benutzer günstigsten Weise liegt.According to a preferred embodiment of the invention, either the cartridge holder or the cartridge can be rotated relative to the housing. The cartridge outlet can be attached to the workpiece in difficult to access places in a desired manner, while it is possible to rotate the housing so that the operating lever to be operated by hand is in the most convenient manner for the user.

Der Kartuschenhalter ist ein einstückiges Teil, das als Spritzgußteil hergestellt werden kann. Es ist nicht erforderlich, daß der Kartuschenhalter sich über die gesamte Länge der Kartusche erstreckt. Insbesondere solche Kartuschen, die aus Metall bestehen, haben häufig am rückwärtigen Ende einen Bördelrand. Ein solcher Bördelrand kann dazu benutzt werden, die Kar­tusche axial an dem Gehäuse zu fixieren. In diesem Fall erfolgt die axiale Abstützung der Kartusche am rück­wärtigen Ende. Bei einer anderen Ausführungsform, bei der die gesamte Länge des Kartuschenkörpers von dem Kartuschenhalter umgeben ist, erfolgt die Abstützung an der vorderen Schulter der Kartusche mit einem starren Ringkragen.The cartridge holder is a one-piece part that can be manufactured as an injection molded part. It is not necessary for the cartridge holder to extend the entire length of the cartridge. Cartridges made of metal in particular often have a flanged edge at the rear end. Such a flanged edge can be used to axially fix the cartridge to the housing. In this case, the cartridge is axially supported at the rear end. In another embodiment, in which the entire length of the cartridge body is surrounded by the cartridge holder, the support is carried out on the front shoulder of the cartridge with a rigid ring collar.

Im folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

In Fig. 1 ist das Auspreßwerkzeug 10 zusammen mit der zugehörigen Kartusche 11 dargestellt. Die Kartusche weist einen langgestreckten zylindrischen Kartuschen­körper 12, an dessem einen Ende der Auslaßstutzen 12a angeordnet ist, der eine abtrennbare Kappe aufweist und durch den hindurch die pastöse Masse aus der Kartusche ausgepreßt wird. Das rückwärtige Ende des Kartuschen­körpers 12 ist offen. In dem Kartuschenkörper befindet sich ein (nicht dargestellter) Kolben, der durch das Auspreßwerkzeug nach vorne gedrückt wird, um die pastöse Masse aus der Kartusche herauszupressen.In Fig. 1, the extrusion tool 10 is shown together with the associated cartridge 11. The cartridge has an elongated cylindrical cartridge body 12, at the end of which the outlet nozzle 12a is arranged, which has a detachable cap and through which the pasty mass is pressed out of the cartridge. The rear end of the cartridge body 12 is open. A piston (not shown) is located in the cartridge body and is pressed forward by the extrusion tool in order to press the pasty mass out of the cartridge.

Die Kartusche 11 wird in den rohrförmigen Kartuschen­halter 13 des Auspreßwerkzeugs 10 eingesetzt. Dieser Kartuschenhalter 13 hat am vorderen Ende eine ring­förmige Anschlagschulter 14 mit einer Öffnung 15 für den Durchtritt des Auslaßstutzens 12a bzw. der Düse der Kartusche 11. Sein Innendurchmesser ist so bemessen, daß die Kartusche 11 leicht in den Kartuschenhalter 13 eingeschoben werden kann. Das Einschieben der Kartusche 11 in den Kartuschenhalter 13 erfolgt vom offenen rück­wärtigen Ende 13a des Kartuschenhalters her.The cartridge 11 is inserted into the tubular cartridge holder 13 of the extrusion tool 10. This Cartridge holder 13 has at the front end an annular stop shoulder 14 with an opening 15 for the passage of the outlet nozzle 12a or the nozzle of the cartridge 11. Its inside diameter is dimensioned such that the cartridge 11 can be easily inserted into the cartridge holder 13. The cartridge 11 is inserted into the cartridge holder 13 from the open rear end 13a of the cartridge holder.

Das rückwärtige Ende des Kartuschenhalters 13 ist mit einem Schnellverschluß 16 an dem Gehäuse 17 des Aus­preßwerkzeugs drehbar befestigt. Das Gehäuse 17 enthält den Vorschubmechanismus 18 zum schrittweisen Vortreiben einer Stange 19, die an ihrem vorderen Ende einen Vor­schubteller 20 aufweist, in dem Kartuschenhalter 13. Der Vorschubteller 20 wird von hinten gegen den im Kar­tuschenkörper 12 befindlichen Kolben gesetzt und treibt diesen nach vorne. Die Stange 19 hat eine solche Länge, daß sie sich durch den Kartuschenhalter 13 und durch das Gehäuse 17 hindurch erstrecken kann und an ihrem rückwärtigen Ende befindet sich ein Rückzugsknopf 21, mit dem die Stange 19 nach Entriegelung manuell zurück­gezogen werden kann.The rear end of the cartridge holder 13 is rotatably fastened to the housing 17 of the extrusion tool with a quick-release fastener 16. The housing 17 contains the feed mechanism 18 for gradually advancing a rod 19, which has a feed plate 20 at its front end, in the cartridge holder 13. The feed plate 20 is set from behind against the piston located in the cartridge body 12 and drives it forward. The rod 19 has a length such that it can extend through the cartridge holder 13 and through the housing 17 and at its rear end there is a retraction button 21 with which the rod 19 can be manually retracted after unlocking.

Das Gehäuse 17 ist pistolenförmig ausgebildet und es weist einen gehäusefesten Handgriff 22 und einen damit gelenkig verbundenen Abzugshebel 23 auf.The housing 17 is pistol-shaped and it has a handle 22 fixed to the housing and a trigger lever 23 connected to it in an articulated manner.

Das vordere Ende des Gehäuses 17 ist mit einem am Ge­häuse angebrachten Deckel 24 verschlossen, durch den die Stange 19 hindurchführt. An diesem Deckel 24 stützt sich eine Feder 25 ab, die einen die Stange 19 umgeben­den Schieber 26 nach hinten drückt. An dem Schieber 26 ist gelenkig eine Klinke 27 angebracht, die durch eine Nase 28 des Abzugshebels 23 nach vorne geschwenkt wird, wenn der Abzugshebel 23 gegen den Handgriff 22 gezogen wird. Dabei verkantet sich die Klinke 27 an der Stange 19, so daß Schieber 26 und Klinke 27 kraftschlüssig mit der Stange 19 verbunden werden. Beim Weiterbewegen des Abzugshebels 23 in Richtung auf den Handgriff 22 wird der Schieber 26 nach vorne bewegt, wobei er durch die Klinke 27 die Stange 19 mitnimmt. Wird der Abzugshebel 23 losgelassen, dann drückt die Feder 25 den Schieber wieder zurück, während die Stange 19 in der vorge­schobenen Stellung verbleibt.The front end of the housing 17 is closed by a cover 24 attached to the housing, through which the rod 19 passes. A spring 25 is supported on this cover 24, which presses a slider 26 surrounding the rod 19 to the rear. On the slider 26, a pawl 27 is articulated, which by a Nose 28 of the trigger lever 23 is pivoted forward when the trigger lever 23 is pulled against the handle 22. The pawl 27 is tilted on the rod 19 so that the slide 26 and the pawl 27 are non-positively connected to the rod 19. When the trigger lever 23 is moved further in the direction of the handle 22, the slide 26 is moved forward, taking the rod 19 with it through the pawl 27. If the trigger lever 23 is released, the spring 25 pushes the slide back again, while the rod 19 remains in the advanced position.

An der Rückwand 30 des Gehäuses 17 ist eine Feder 32 abgestützt, die gegen eine Sperrklinke 33 drückt, welche eine Öffnung für den Durchgang der Stange 19 hat. Die Sperrklinke 33 läßt eine Bewegung der Stange 19 nach vorne zu, verhindert aber das Rückziehen der Stange 19. Die Sperrklinke 33 ist an einem gehäuse­festen Anschlag 34 abgestützt und sie hat jenseits des Anschlags 34 einen Hebelarm 33a, gegen den der Abzugs­hebel 23 drückt, wenn er durch die Hand des Benutzers freigegeben ist. Gegen die Wirkung der Feder 32 wird in der Lösestellung die Sperrklinke 33 um den Anschlag 34 herum so verschwenkt, daß sie die Stange 19 in beiden Richtungen freigibt, so daß in der Lösestellung die Stange 19 frei bewegt werden kann.On the rear wall 30 of the housing 17, a spring 32 is supported, which presses against a pawl 33, which has an opening for the passage of the rod 19. The pawl 33 allows the rod 19 to move forward, but prevents the rod 19 from retracting. The pawl 33 is supported on a stop 34 fixed to the housing and, beyond the stop 34, it has a lever arm 33a against which the trigger lever 23 presses when it is released by the user's hand. Against the action of the spring 32, the pawl 33 is pivoted around the stop 34 in the release position so that it releases the rod 19 in both directions, so that the rod 19 can be moved freely in the release position.

Der rohrförmige Kartuschenhalter 13 ist an seinem rück­wärtigen Ende über den Schnellverschluß 16 mit dem Ge­häuse 17 verbunden. Dieser Schnellverschluß 16 weist eine Hülse 35 auf, die am rückwärtigen Ende einen nach innen gerichteten Flansch 36 hat. Dieser Flansch 36 greift in eine Nut 37 des Gehäuses 17 ein. Die Hülse 35 ist relativ zum Gehäuse 17 um ihre Längsachse drehbar. Es können auch Rastelemente vorgesehen sein, die eine solche Drehung verhindern.The tubular cartridge holder 13 is connected at its rear end to the housing 17 via the quick-release fastener 16. This quick-release fastener 16 has a sleeve 35 which has an inwardly directed flange 36 at the rear end. This flange 36 engages in a groove 37 of the housing 17. The sleeve 35 is rotatable relative to the housing 17 about its longitudinal axis. It can also be provided locking elements that prevent such rotation.

Aus den Fign. 2 und 3 ist ersichtlich, daß die Hülse 35 federnde Zungen 38 aufweist, die in Längsrichtung der Hülse 35 verlaufen und an ihren vorderen Enden Rast­elemente 39 tragen, welche nach innen weisen. Die Rast­elemente 39 dringen in Durchbrüche 40 des Kartuschen­halters 13 ein und sie weisen an einer Seite Abschrä­gungen 41 auf, die es ermöglichen, das Rastelement 39 aus dem Druchbruch 40 herauszuheben, wenn der Kar­tuschenhalter 13 relativ zu der Hülse 35 mit Kraft ge­dreht wird. Auch an den vorderen Enden der Rastelemente 39 sind gemäß Fig. 1 Abschrägungen 42 vorgesehen, die das Einschieben des Kartuschenhalters 13 in die Hülse 35 ermöglichen, wobei die Rastelemente 39 radial nach außen gedrückt werden, bis sie in den Druchbrüchen 40 einrasten.From Figs. 2 and 3 it can be seen that the sleeve 35 has resilient tongues 38 which extend in the longitudinal direction of the sleeve 35 and carry latching elements 39 at their front ends which point inwards. The locking elements 39 penetrate openings 40 in the cartridge holder 13 and they have bevels 41 on one side, which make it possible to lift the locking element 39 out of the opening 40 when the cartridge holder 13 is rotated with force relative to the sleeve 35. According to FIG. 1, bevels 42 are also provided at the front ends of the latching elements 39, which enable the cartridge holder 13 to be inserted into the sleeve 35, the latching elements 39 being pressed radially outward until they snap into the openings 40.

Die Kartusche 11 wird vom rückwärtigen Ende des Kar­tuschenhalters 13 her in diesen eingeschoben. Dann wird der Kartuschenhalter 13 zusammen mit der eingesetzten Kartusche 11 in die Hülse 35 eingeschoben, bis die Rastelemente 39 in den Druchbrüchen 40 einrasten. Das Auspreßwerkzeug kann nun benutzt werden, indem der Abzugshebel 23 gegen den Handgriff 22 gezogen und dann losgelassen wird. Dadurch wird die Stange 19 zusammen mit dem Teller 20 schrittweise vorgeschoben.The cartridge 11 is inserted into the cartridge holder 13 from the rear end thereof. Then the cartridge holder 13 is inserted together with the inserted cartridge 11 into the sleeve 35 until the locking elements 39 snap into the openings 40. The extrusion tool can now be used by pulling the trigger lever 23 against the handle 22 and then releasing it. As a result, the rod 19 is gradually advanced together with the plate 20.

Das Ausführungsbeispiel der Fign. 4 und 5 unterscheidet sich von dem ersten Ausführungsbeispiel nur durch eine andere Ausbildung des Schnellverschlusses 16. Der Schnellverschluß weist federnde Zungen 43 am rück­wärtigen Ende des Kartuschenhalters 13 auf. Diese federnden Zungen 43 sind durch längslaufende Schlitze begrenzt und ihren rückwärtigen Enden befinden sich nach innen gerichtete Rastelemente 44, die in eine um­laufende Nut 37 am Gehäuse 17 eindringen können. Auf dem Kartuschenhalter 13 sitzt eine Schiebehülse 45, die den Kartuschenhalter umgibt und in Längsrichtung ver­schoben werden kann. Wenn diese Schiebehülse über die federnden Zungen 43 geschoben wird, sind die Rast­elemente 44 in der Nut 37 axial blockiert und der Kar­tuschenhalter 13 ist gegen Abziehen vom Gehäuse 17 ge­sichert. Wird die Schiebehülse 45 gemäß Fig. 5 nach vorne geschoben, dann kann der Kartuschenhalter 13 vom Gehäuse 17 abgezogen werden. Hierbei gleiten die Schrägflanken 46, die die vorderen Begrenzungen der Rastelemente 44 bilden, auf der Schrägfläche 47 der Nut 37, so daß die Zungen 43 gemäß Fig. 5 radial nach außen federn. An den rückwärtigen Enden der Rastelemente 44 sind schräge Rückflanken 48 vorgesehen, so daß die Zungen 43 beim Ansetzen des Kartuschenhalters 13 gegen das Gehäuse 17 nach außen gedrängt werden und dann federnd in der Nut 37 einrasten.The embodiment of FIGS. 4 and 5 differs from the first exemplary embodiment only in a different design of the quick-release fastener 16. The quick-release fastener has resilient tongues 43 at the rear end of the cartridge holder 13. These Resilient tongues 43 are delimited by longitudinal slots and their rear ends are inwardly directed locking elements 44 which can penetrate into a circumferential groove 37 on the housing 17. On the cartridge holder 13 there is a sliding sleeve 45 which surrounds the cartridge holder and can be moved in the longitudinal direction. When this sliding sleeve is pushed over the resilient tongues 43, the locking elements 44 are axially blocked in the groove 37 and the cartridge holder 13 is secured against being pulled off the housing 17. If the sliding sleeve 45 is pushed forward according to FIG. 5, the cartridge holder 13 can be removed from the housing 17. Here, the inclined flanks 46, which form the front boundaries of the latching elements 44, slide on the inclined surface 47 of the groove 37, so that the tongues 43 spring radially outwards according to FIG. 5. At the rear ends of the locking elements 44, oblique rear flanks 48 are provided, so that the tongues 43 are pushed outwards against the housing 17 when the cartridge holder 13 is attached and then snap into the groove 37 in a resilient manner.

Bei dem Ausführungsbeispiel von Fig. 6 ist der Kar­tuschenhalter 13 ein kurzes Rohr, das vorne offen ist, so daß die Kartusche 11 aus ihm heraussteht. Dabei können Kartuschen 11 oder 11a unterschiedlicher Längen benutzt werden. Die Kartuschen weisen am rückwärtigen Ende ein nach außen stehenden Rückhalteelement 50 auf, das vorzugsweise als umlaufender Flansch oder Bördel­rand ausgebildet ist. Solche Bördelränder sind bei­spielsweise bei Metallkartuschen üblich. Dieses Rück­halteelement 50 stößt gegen eine ringförmige Schulter 51 im Inneren des Kartuschenhalters 13. Der Kartuschen­halter 13 weist ferner eine Muffe 52 auf, die auf einer Zylinderfläche 53 des Gehäuses 17 aufgeschoben ist. An der Zylinderfläche 53 sind nach außen abstehende An­sätze 54 vorgesehen, die in entsprechende Ausnehmungen 55 der Muffe 52 eingreifen. Ferner erstrecken sich von den Ausnehmungen 55 längslaufende Kanäle 56 zum rück­wärtigen Ende der Muffe 52. Die Ausnehmungen 55 bilden zusammen mit den Kanälen 56 einen Bajonettverschluß. Beim Aufstecken der Muffe 52 auf die Zylinderfläche 53 gleiten die Kanäle 56 über die Ansätze 54. Wenn die Ansätze 54 in die Ausnehmungen 55 eingedrungen sind, wird die Muffe 52 relativ zum Gehäuse 17 gedreht, so daß die Ansätze 55 nicht mehr mit den Kanälen 56 aus­gerichtet sind und der Kartuschenhalter 13 gegen Ab­ziehen vom Gehäuse 17 gesichert ist.6, the cartridge holder 13 is a short tube which is open at the front so that the cartridge 11 protrudes from it. Cartridges 11 or 11a of different lengths can be used. At the rear end, the cartridges have an outward retaining element 50, which is preferably designed as a circumferential flange or flanged edge. Such flanged edges are common, for example, in metal cartridges. This retaining element 50 abuts an annular shoulder 51 inside the cartridge holder 13. The cartridge holder 13 also has a sleeve 52, which is on a Cylinder surface 53 of the housing 17 is pushed on. On the cylinder surface 53 outwardly projecting lugs 54 are provided which engage in corresponding recesses 55 in the sleeve 52. Furthermore, longitudinal channels 56 extend from the recesses 55 to the rear end of the sleeve 52. The recesses 55 together with the channels 56 form a bayonet catch. When the sleeve 52 is fitted onto the cylindrical surface 53, the channels 56 slide over the projections 54. When the projections 54 have penetrated into the recesses 55, the sleeve 52 is rotated relative to the housing 17, so that the projections 55 no longer match the channels 56 are aligned and the cartridge holder 13 is secured against being pulled off the housing 17.
