Abstract

The device has a coupling section (14) with a chamber (17) for receiving a matching coupling section of a power drive-in tool (40). Two locking units (21, 22) displaced in opposite directions are displaceable between locking and release positions. A locking section projects into the chamber in the locking position for engaging a recess. The locking section is withdrawn from the chamber in the release position. A spring biases the locking units to the locking position. An actuation section is accessible from outside to manually displace the locking units from the locking to release position.

Description

Die vorliegende Erfindung betrifft eine Befestigungsmittel-Zuführeinrichtung für ein kraftbetriebenes Eintreibgerät der im Oberbegriff von Patentanspruch 1 genannten Art.The present invention relates to a fastener-feeding device for a power driven tacker referred to in the preamble of claim 1. Art.

Befestigungsmittel-Zuführeinrichtung für kraftbetriebene Eintreibgeräte, wie z. B. Schraubgeräte, weisen zum Ansetzen an einen Untergrund ein Kopfteil auf, das der Führung von Befestigungselementen, wie z. B. Schrauben, vor und während dem Eintreibvorgang dient. Dieses Kopfteil kann z. B. Teil eines Befestigungsmittelmagazins oder einer Befestigungsmitteltransporteinrichtung sein, welche an einen Flansch eines Eintreibgerätes aufsetzbar sind.Fastener supply device for power operated Eintreibgeräte, such. B. screwdrivers, have to attach to a substrate on a head part, the leadership of fasteners such. As screws, before and during the driving operation. This headboard can, for. B. be part of a fastener magazine or a fastener transport device, which can be placed on a flange of a tacker.

Aus der US 2002/0108995 A1 ist eine Schraubenzuführeinrichtung für ein Eintreib- bzw. Schraubgerät bekannt, die mit einer ersten Baueinheit über einen Klemmring an einem Flansch des Schraubgerätes angeordnet ist. Eine zweite Baueinheit der Schraubenzuführeinrichtung ist teleskopierbar gegenüber der ersten Baueinheit angeordnet und weist an seinem in Arbeitsrichtung liegenden Ende ein Nasenteil auf, das zur Führung einer Schraube zwei sich gegenüberliegende, verschwenkbare Backenelemente aufweist. In geschlossenem Zustand, d.h. wenn die Backenelemente mit ihren freien Enden aneinanderliegen, können die Backenelemente ein Befestigungsmittel bzw. eine Schraube führen. Während eines Einschraubvorganges werden zwei Stifte jeweils von einer Steuerschulter eines jeden Backenelementes abgehoben um ein Auseinanderschwenken und damit ein Öffnen der Backenelemente zu ermöglichen. Dieses Öffnen erfolgt dann beim weiteren Einschraubvorgang durch das Vorbeilaufen einer Schraube an den, der Schraube zugewandten Innenflächen der Backenelemente.From the US 2002/0108995 A1 is a Schraubenzuführeinrichtung for a driving or screwing known, which is arranged with a first unit via a clamping ring on a flange of the screwdriver. A second assembly of the screw feed is arranged telescopically with respect to the first unit and has at its end in the direction of work a nose part, which has two opposing, pivotable jaw members for guiding a screw. In the closed state, that is, when the jaw members abut each other with their free ends, the jaw members may carry a fastener or a screw. During a screwing two pins are each lifted from a control shoulder of each jaw member to a swivel apart and thus to allow opening of the jaw members. This opening then takes place during further screwing by the passage of a screw past the, the screw facing the inner surfaces of the jaw members.

Von Nachteil hierbei ist, dass die Backenelemente in der Regel erst durch den gegenüber dem Schaft verbreiterten Kopf der Schraube vollständig geöffnet werden, wobei die zum vollständigen Öffnen der Klauen notwendigen Kräfte vom Durchmesser und der Geometrie der Schraubenköpfe abhängen. Das Öffnungsverhalten der Backenelemente fällt daher für unterschiedliche Schraubentypen unterschiedlich aus.The disadvantage here is that the jaw elements are usually completely opened only by the head of the screw widened with respect to the shaft, wherein the forces necessary for the complete opening of the jaws are of the diameter and the geometry depend on the screw heads. The opening behavior of the jaw elements is therefore different for different screw types.

Die Aufgabe der vorliegenden Erfindung liegt darin, eine Befestigungsmittel-Zuführeinrichtung für ein kraftbetriebenes Eintreibgerät zur Verfügung zu stellen, bei der unabhängig vom Typ des einzutreibenden Befestigungsmittels ein gleichmässiges Öffnungsverhalten der Backenelemente und eine gute Führung der Schrauben erreicht wird.The object of the present invention is to provide a fastener supply device for a power driven tacker, in which, regardless of the type of fastener to be driven in a uniform opening behavior of the jaw members and a good guidance of the screws is achieved.

Diese Aufgabe wird erfindungsgemäss durch die in Anspruch 1 genannten Massnahmen erreicht.This object is achieved according to the invention by the measures mentioned in claim 1.

Demnach sind an den Backenelementen Betätigungsmittel angeordnet, die über Steuermittel an der ersten Baueinheit zum Verschwenken der Backenelemente von der geschlossenen Position in die geöffnete Position betätigbar sind.Accordingly, actuating means are arranged on the jaw elements, which can be actuated via control means on the first unit for pivoting the jaw members from the closed position to the open position.

Durch diese Massnahme wird ein gleichmässiges Öffnungsverhalten der Backenelemente erreicht, das unabhängig von den Befestigungsmitteln bzw. deren Kopfdurchmessern ist. Das Öffnen der Backenelemente erfordert dabei immer einen gleichbleibenden Kraftaufwand. Ferner ist eine optimale Führung der Befestigungselemente gewährleistet.By this measure, a uniform opening behavior of the jaw elements is achieved, which is independent of the fasteners and their head diameters. The opening of the jaw elements always requires a constant effort. Furthermore, optimal guidance of the fastening elements is ensured.

Vorteilhaft ist die erste Baueinheit als Gehäuse ausgebildet. Die Steuermittel sind dabei als Innenflächen des Gehäuses ausgebildet. Hierdurch können auf technisch einfache Weise die Steuermittel ohne zusätzliche Bauteile bereitgestellt werden.Advantageously, the first unit is designed as a housing. The control means are formed as inner surfaces of the housing. As a result, the control means can be provided without additional components in a technically simple manner.

Günstig ist es ferner, wenn die Betätigungsmittel als Vorsprünge ausgebildet sind, die jeweils in einer der Werkzeugachse abgewandten Richtung von den Backenelementen abragen. Die Betätigungsmittel können hierdurch auf einfache Weise mit den Steuermitteln an der ersten Baueinheit zusammenwirken, wenn die zweite Baueinheit bei einem Eintreibvorgang in die erste Baueinheit hineingeschoben wird.It is also favorable if the actuating means are designed as projections, which in each case protrude in a direction away from the tool axis of the jaw elements. The actuating means can thereby interact in a simple manner with the control means on the first unit when the second unit is pushed in a driving operation in the first unit.

Von Vorteil ist es ferner, wenn die Vorsprünge der ersten Baueinheit zugewandte rampenbis kuppelförmig ansteigende Flanken aufweisen, wodurch ein Verkanten oder Verhaken und ein hoher Kraftaufwand beim Verschwenken der Backenelemente über die Steuermittel vermieden wird.It is also advantageous if the projections of the first unit have facing ramps to dome-shaped rising flanks, whereby tilting or entanglement and a high expenditure of force during pivoting of the jaw elements via the control means is avoided.

Weitere Vorteile und Massnahmen der Erfindung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung und den Zeichnungen. In den Zeichnungen ist die Erfindung in einem Ausführungsbeispiel dargestellt.Further advantages and measures of the invention will become apparent from the dependent claims, the following description and the drawings. In the drawings, the invention is shown in one embodiment.

Die Figuren 1 bis 3 zeigen eine insgesamt mit 10 bezeichnete erfindungsgemässe Befestigungsmittel-Zuführeinrichtung die mit einem Kupplungsabschnitt 14 an einem Flansch 41 eines in den Figuren nur angedeuteten, kraftbetriebenen Eintreibgerätes 40 lösbar festgelegt ist. Das hier teilweise wiedergegebene Eintreibgerät ist dabei als elektrisch betriebenes Schraubgerät ausgebildet. Die Befestigungsmittel-Zuführeinrichtung 10 ist als Schraubenmagazin mit integriertem Transportmechanismus 32 für den Transport eines Schraubenmagazinstreifens 30 ausgebildet. In der Befestigungsmittel-Zuführeinrichtung 10 ist ein als Schraubwerkzeug ausgebildetes Eintreibwerkzeug 13 geführt, welches über das kraftbetriebene Eintreibgerät 40 drehbetätigt werden kann.Figures 1 to 3 show a generally designated 10 fastener supply means according to the invention which is releasably fixed with a coupling portion 14 on a flange 41 of a power driven Eintreibgerätes 40 only indicated in the figures. The partially reproduced tacking device is designed as an electrically operated screwdriver. The fastener supply device 10 is designed as a screw magazine with integrated transport mechanism 32 for the transport of a screw magazine strip 30. In the fastener-supply device 10 designed as a screw driving tool 13 is guided, which can be rotationally actuated via the power driven tacker 40.

Die Befestigungsmittel-Zuführeinrichtung 10 weist eine erste Baueinheit 11, die den Kupplungsabschnitt 14 beinhaltet und die hier als Führungsgehäuse ausgebildet ist, und eine zweite Baueinheit 19, die verschieblich an der ersten Baueinheit 11 gehalten ist, auf. Die zweite Baueinheit 19 trägt den Transportmechanismus 32 und führt den Schraubenmagazinstreifen 30. Ferner weist die zweite Baueinheit 19 ein Kopfteil 20 auf, welches mit einer Stirnfläche 18 an einen Untergrund U ansetzbar ist. An dem Kopfteil 20 sind seitlich einer durch das Eintreibwerkzeug 13 definierten Werkzeugachse A zwei Backenelemente 21, 22 angeordnet. Diese Backenelemente 21, 22 sind an Schwenklagern 25 verschwenkbar am Kopfteil 20 gehalten und weisen an ihren der Stirnfläche 18 zugewandten Enden Backen 23 auf, die in einer geschlossenen Position 16, die aus Fig. 1 ersichtlich ist, ein Befestigungsmittel 31, wie eine Schraube, halten und führen können. Die Backen 23 der Backenelemente 21, 22 müssen dabei nicht unbedingt nahtlos aneinanderliegen, sondern können in Abhängigkeit von der Schaftdicke des Befestigungsmittels 31, welches sie führen, eine kleine Distanz zueinander aufweisen. Die Backenelemente 23 weisen zur Führung des Befestigungsmittels 31 jeweils einen Teil eines Führungskanals 29 auf, durch den das Befestigungsmittel 31 hindurchführbar ist. Die Backenelemente 21, 22 sind über Federelemente 26, die sich einerseits an den Backen 23 und andererseits an Vorsprüngen 27 an dem Kopfteil 20 abstützen in Richtung auf die geschlossene Position 16 elastisch beaufschlagt. An den, der Stirnfläche 18 abgewandten Enden der Backenelemente 21, 22 sind als Vorsprünge ausgebildete Betätigungsmittel 24 angeordnet, die jeweils in einer der Werkzeugachse A abgewandten Richtung von den Backenelemente 21, 22 abragen. Der ersten Baueinheit 11 zugewandte Flanken 15 der Betätigungsmittel 24 sind rampen- bzw. kuppelförmig ansteigend ausgebildet.The fastener supply device 10 has a first assembly 11, which includes the coupling portion 14 and which is formed here as a guide housing, and a second unit 19, which is displaceably held on the first unit 11, on. The second structural unit 19 carries the transport mechanism 32 and guides the screw magazine strip 30. Further, the second structural unit 19 has a head part 20 which can be attached with an end face 18 to a substrate U. On the head part 20, two jaw elements 21, 22 are arranged laterally of a tool axis A defined by the driving tool 13. These jaw elements 21, 22 are pivotably held on pivot bearing 25 on the head part 20 and have at their end face 18 facing the ends of jaws 23 which in a closed position 16, which is shown in FIG. 1, a fastening means 31, such as a screw, can hold and lead. The jaws 23 of the jaw members 21, 22 do not necessarily have to be seamless abut each other, but may have a small distance from each other depending on the shaft thickness of the fastening means 31, which they lead. The jaw elements 23 each have a part of a guide channel 29 for guiding the fastening means 31, through which the fastening means 31 can be passed. The jaw elements 21, 22 are elastically acted upon by spring elements 26, which are supported on the one hand on the jaws 23 and on the other hand on projections 27 on the head part 20 in the direction of the closed position 16. At the ends of the jaw members 21, 22 facing away from the end face 18, actuating means 24 designed as projections are arranged, which in each case protrude from the jaw elements 21, 22 in a direction away from the tool axis A. The first unit 11 facing flanks 15 of the actuating means 24 are formed ramping or dome-shaped rising.

An der ersten Baueinheit 11 sind Steuermittel 12 angeordnet, die durch Innenwände der Baueinheit 11 gebildet sind und gegen die die Betätigungsmittel 24 mit ihren Flanken 15 bewegbar sind.At the first unit 11 control means 12 are arranged, which are formed by inner walls of the unit 11 and against which the actuating means 24 are movable with their flanks 15.

Wird das Eintreibgerät 40 mit der daran angeordneten Befestigungsmittel-Zuführeinrichtung 10 an einen Untergrund U angedrückt und ein Befestigungsmittel 31 in den Untergrund U eingetrieben, dann wird die zweite Baueinheit 12 in die erste Baueinheit 11 in Richtung des Pfeils 33 hineinbewegt. Während dieser Bewegung laufen die Betätigungsmittel 24 an den Backenelementen 21, 22 mit ihren rampen- bzw. kuppelförmig ansteigenden Flanken 15 gegen die Steuermittel 12 an der ersten Baueinheit 11 und werden durch diesen Kontakt in Richtung auf die Werkzeugachse A versetzt. Hierdurch verschwenken die Backenelemente 21, 22 von ihrer geschlossenen Position 16 in eine geöffnete Position 17, in der die Backen 23 das Befestigungsmittel 31 nicht mehr führen und frei geben. Die Backen 23 liegen dann in einer grösseren Distanz zur Werkzeugachse A, als in ihrer geschlossenen Position 16. Der Vorgang des Auseinanderfahrens der Backen 23 erfolgt noch bevor das Befestigungsmittel 31 vollständig in den Untergrund U eingeschraubt ist.If the tacker 40 is pressed with the attached thereto fastener-feeding device 10 to a substrate U and driven a fastener 31 in the ground U, then the second unit 12 is moved into the first unit 11 in the direction of the arrow 33. During this movement, the actuating means 24 run on the jaw members 21, 22 with their ramps or dome-shaped rising flanks 15 against the control means 12 on the first unit 11 and are offset by this contact in the direction of the tool axis A. As a result, the jaw elements 21, 22 pivot from their closed position 16 into an open position 17, in which the jaws 23 no longer guide and release the fastening means 31. The jaws 23 are then located at a greater distance to the tool axis A, as in its closed position 16. The process of moving apart of the jaws 23 takes place before the fastener 31 is completely screwed into the substrate U.
