Abstract
Description
Die Erfindung betrifft ein Auspressgerät zum Auspressen von Kartuschen, mit einem Vorschubmechanismus für eine Kolbenstange, einem Gehäuse, an dem ein Übersetzungshebel zum Betätigen des Vorschubmechanismus schwenkbar befestigt ist, und einem gehäusefesten Handgriff, an dem ein Betätigungshebel schwenkbar befestigt ist.The invention relates to a dispensing device for squeezing cartridges, comprising a feed mechanism for a piston rod, a housing on which a transmission lever for actuating the feed mechanism is pivotally mounted, and a housing-fixed handle on which an actuating lever is pivotally mounted.
Solche Auspressgeräte werden beispielsweise im Baubereich zum Auspressen von Kartuschen verwendet, die mit Silikon oder anderen flüssigen bzw. zähflüssigen Baustoffen gefüllt sind. Diese Kartuschen haben üblicherweise einen zylindrischen Grundkörper mit einer an einer Stirnwand angeordneten Ausgabeöffnung. Die gegenüberliegende Stirnwand ist durch einen im zylindrischen Grundkörper verschiebbaren Stempel gebildet, sodass durch ein Verschieben dieser Stirnwand das Volumen der Kartusche geändert und dadurch der Inhalt der Kartusche aus der Ausgabeöffnung herausgepresst werden kann. Das Auspressgerät ermöglicht eine exakte Dosierung sowie ein genaues Auftragen des jeweiligen Baustoffs. Üblicherweise hat das Auspressgerät einen an einer Kolbenstange angeordneten Kolben, der an dem Stempel angreifen und diesen zum Auspressen der Kartusche gegen die Ausgabeöffnung drängen kann. Die Kolbenstange wird dabei über einen Vorschubmechanismus angetrieben, welcher beispielsweise durch einen schwenkbar an einem Gehäuse befestigten Übersetzungshebel betätigt wird. Dieser Übersetzungshebel ist üblicherweise mit einem Betätigungshebel gekoppelt, der schwenkbar an einem gehäusefesten Handgriff befestigt ist.Such Auspressgeräte be used for example in the construction sector for squeezing cartridges that are filled with silicone or other liquid or viscous building materials. These cartridges usually have a cylindrical base body with an outlet opening arranged on an end wall. The opposite end wall is formed by a displaceable in the cylindrical base body stamp, so changed by moving this end wall, the volume of the cartridge and thereby the contents of the cartridge can be pressed out of the discharge opening. The dispensing device allows exact dosage and accurate application of the respective building material. Usually, the dispensing device has a piston arranged on a piston rod, which can engage the punch and urge it to press the cartridge against the dispensing opening. The piston rod is driven by a feed mechanism, which is actuated for example by a pivotally mounted on a housing transmission lever. This transmission lever is usually coupled to an actuating lever which is pivotally mounted on a housing-fixed handle.
Bei herkömmlichen Auspressgeräten wird mit jedem Hub des Betätigungshebels ein im Wesentlichen konstantes Baustoffvolumen ausgepresst. Dabei muss die Bedienperson zum Auspressen des Baustoffs eine von der Zähigkeit des Baustoffs abhängige Auspresskraft aufbringen. Bei eher zähflüssigen Baustoffen kann dies dazu führen, dass die Bedienperson schnell ermüdet oder u.U. die notwendige Auspresskraft gar nicht aufbringen kann. Bei eher dünnflüssigen Baustoffen ist die erforderliche Auspresskraft hingegen gering, und es besteht bei vielen Bedienpersonen der Wunsch, das ausgepresste Baustoffvolumen je Hub zu vergrößern.In conventional Auspressgeräten with each stroke of the actuating lever, a substantially constant volume of building material is squeezed out. In this case, the operator must apply for pressing the building material dependent on the toughness of the building material pressing force. In the case of rather viscous building materials, this can lead to the operator quickly getting tired or possibly not even being able to apply the necessary extrusion force. At rather low viscosity Building materials, the required Auspresskraft, however, low, and there is a desire many operators to increase the expressed volume of building material per stroke.
Um diesen Nachteil herkömmlicher Auspressgeräte zu überwinden, offenbart die
Aufgabe der Erfindung ist die Schaffung eines dauerhaften und robusten Auspressgeräts, bei dem sich das ausgepresste Baustoffvolumen pro Hub des Betätigungshebels einfach und schnell verändern lässt.The object of the invention is to provide a durable and robust Auspressgeräts in which the expressed volume of building material per stroke of the operating lever can be changed quickly and easily.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Auspressgerät der eingangs genannten Art, bei dem der Übersetzungshebel und der Betätigungshebel über eine Kulissenführung gelenkig miteinander verbunden sind. Die Kopplung der beiden Hebel über eine Kulissenführung ist hervorragend geeignet, um eine wenigstens zweistufige, robuste und schnelle Verstellmöglichkeit des Übersetzungsverhältnisses zwischen dem Hub des Betätigungshebels und dem ausgepressten Baustoffvolumen bereitzustellen.This object is achieved by a Auspressgerät of the aforementioned type, wherein the transmission lever and the actuating lever are pivotally connected to each other via a slotted guide. The coupling of the two levers via a sliding guide is ideally suited to provide an at least two-stage, robust and fast adjustment of the transmission ratio between the stroke of the actuating lever and the pressed building material volume.
In einer Ausführungsform umfasst die Kulissenführung eine Kulisse im Übersetzungshebel, eine Kulisse im Betätigungshebel und einen Kulissenstein, wobei der Kulissenstein sowohl in die Kulisse des Übersetzungshebels als auch in die Kulisse des Betätigungshebels eingreift.In one embodiment, the slide guide comprises a link in the transmission lever, a link in the actuating lever and a sliding block, wherein the sliding block engages both in the backdrop of the transmission lever and in the backdrop of the actuating lever.
In dieser Ausführungsform können der Kulissenstein als Führungsstift und die Kulissen jeweils als Langlöcher ausgebildet sein. Eine solche Konstruktion lässt sich fertigungstechnisch einfach realisieren, erlaubt eine schnelle manuelle Einstellung und ist darüber hinaus äußerst robust.In this embodiment, the sliding block may be formed as a guide pin and the scenes each as slots. Such a design can be easily realized in terms of manufacturing technology, permits rapid manual adjustment and, moreover, is extremely robust.
Vorzugsweise erstreckt sich die Kulisse des schwenkbaren Betätigungshebels in Bezug auf dessen gehäusefestes Schwenklager im Wesentlichen in radialer Richtung längs des Betätigungshebels.Preferably, the gate of the pivotable actuating lever extends in relation to the housing-fixed pivot bearing substantially in the radial direction along the actuating lever.
Analog kann sich die Kulisse des schwenkbaren Übersetzungshebels in Bezug auf dessen gehäusefestes Schwenklager im Wesentlichen in radialer Richtung längs des Übersetzungshebels erstrecken.Similarly, the scenery of the pivotable transmission lever with respect to the housing-fixed pivot bearing extend substantially in the radial direction along the transmission lever.
In einer weiteren Ausführungsform weist der schwenkbare Betätigungshebel einen Stellschieber auf, welcher in Bezug auf das gehäusefeste Schwenklager des Betätigungshebels zwischen einer radial inneren, ersten Stellposition und einer radial äußeren, zweiten Stellposition verschiebbar ist. Durch diesen Stellschieber lässt sich das Übersetzungsverhältnis zwischen dem Hub des Betätigungshebels und dem ausgepressten Baustoffvolumen sehr einfach, nämlich durch einen einzigen Handgriff, variieren.In a further embodiment, the pivotable actuating lever has a locking slide, which is displaceable with respect to the housing-fixed pivot bearing of the actuating lever between a radially inner, first actuating position and a radially outer second actuating position. By this lock slider, the ratio between the stroke of the operating lever and the expressed building material volume can be very easily, namely by a single handle, vary.
Der Stellschieber umfasst dabei vorzugsweise einen Kulissenstein der Kulissenführung.The locking slide preferably comprises a sliding block of the sliding guide.
Ferner kann der Stellschieber zumindest in einer Stellposition arretierbar sein.Furthermore, the lock slider can be locked at least in a parking position.
Hierzu weist die Kulisse des Betätigungshebels bevorzugt einen Hinterschnitt auf, in den der Kulissenstein eingreifen, insbesondere einrasten kann. Durch den Hinterschnitt lassen sich der Stellschieber und damit ein gewünschtes Übersetzungsverhältnis auf einfache Art und Weise fixieren. Ein solcher Hinterschnitt ist üblicherweise in der radial inneren, ersten Stellposition und/oder der radial äußeren, zweiten Stellposition des Stellschiebers vorgesehen. Ferner ist jedoch auch denkbar, dass ein solcher Hinterschnitt in einer Mittenposition zwischen der ersten und zweiten Stellposition vorgesehen ist, um beispielsweise eine dreistufige Verstellbarkeit vorzusehen.For this purpose, the backdrop of the actuating lever preferably has an undercut, in which engage the sliding block, in particular can engage. Through the undercut, the lock slider and thus a desired transmission ratio can be fixed in a simple manner. Such an undercut is usually provided in the radially inner, first actuating position and / or the radially outer, second actuating position of the adjusting slide. Furthermore, however, it is also conceivable that such an undercut is provided in a middle position between the first and second parking position, for example, to provide a three-stage adjustability.
Insbesondere kann der Betätigungshebel über die Kulissenführung mit dem Übersetzungshebel so gekoppelt sein, dass sich der Kulissenstein bei einer Verschiebung des Stellschiebers von seiner ersten Stellposition in seine zweite Stellposition näher an das gehäusefeste Schwenklager des Übersetzungshebels bewegt.In particular, the actuating lever may be coupled via the link guide with the transmission lever so that the sliding block at a Displacement of the locking slide moves from its first parking position to its second parking position closer to the housing-fixed pivot bearing of the transmission lever.
In einer Ausführungsform des Auspressgeräts umfasst der Vorschubmechanismus eine Klemmscheibe, wobei der Übersetzungshebel an der Klemmscheibe angreifen kann.In one embodiment of the dispensing device, the feed mechanism comprises a clamping disk, wherein the transmission lever can engage the clamping disk.
In einer alternativen Ausführungsform des Auspressgeräts ist der Vorschubmechanismus ein Ratschenmechanismus, wobei der Übersetzungshebel an einem Antriebsrad des Ratschenmechanismus angreifen kann.In an alternative embodiment of the dispensing apparatus, the advancing mechanism is a ratchet mechanism, wherein the translating lever can engage a drive wheel of the ratchet mechanism.
