Abstract

A driving apparatus for fasteners, which receives the fasteners, such as nails, pins, or screws attached to a supply belt, has a cutter for cutting off sections of the supply belt as the latter comes out empty of a belt guide channel in which the fasteners are removed, one by one, from the supply belt. Thus, the empty supply belt can be easily removed and prevented from hindering the operation of the driving apparatus. The cutter may be operated manually or by pressure applied by a piston cylinder.

Description

Die Erfindung betrifft ein Einschlaggerät für Befestigungsmittel gemäss Oberbegriff von Anspruch 1.The invention relates to a wrapping device for fasteners according to the preamble of claim 1.

AusderGB-A 1 389 955istein Einschlaggerätder eingangs genannten Art bekannt, bei dem das Abhackmesser mit dem Schlagstössel verbunden ist und bei jedem Einschlaghub das überstehende leere Ende des Haltegurts abtrennt.From GB-A 1 389 955 a knock-in device of the type mentioned at the outset is known, in which the chopping knife is connected to the punch and detaches the protruding empty end of the holding belt on each knock-in stroke.

Dieses Ende des Haltegurts fällt anschliessend auf die Oberfläche des Werkstücks und kann, wenn es nicht entfernt wird, von der Aufsetzfläche des Zylinderfusses in das Werkstück eingedrückt werden, so dass diese Oberfläche beschädigt wird.This end of the tether then falls onto the surface of the workpiece and, if it is not removed, can be pressed into the workpiece from the mounting surface of the cylinder base, so that this surface is damaged.

Der Schlagstössel unterliegt hohen Beschleunigungskräften, so dass die Befestigung zwischen Schlagstössel und Abhackmesser sehr störanfällig ist, wobei ein Abbrechen des Abhackmessers zu unangenehmen Arbeitsunterbrechungen führen kann.The impact ram is subject to high acceleration forces, so that the attachment between the impact ram and the chopping knife is very susceptible to failure, and breaking off the chopping knife can lead to unpleasant interruptions in work.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Einschlaggerät der eingangs genannten Art zu schaffen, bei dem der leere Haltegurt störungsfrei und zuverlässig abtrennbar ist.The invention is therefore based on the object of providing an impact device of the type mentioned at the outset in which the empty tether can be reliably and reliably removed.

Diese Aufgabe wird erfindungsgemäss durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of claim 1.

Durch die unabhängige Anordnung des Abhackmessers vom Schlagstössel besteht nicht die Gefahr, dass dieses häufig abbricht und Störungen verursacht. Der leere Haltegurt wird sicher und zuverlässig in grösserer Länge abgetrennt und kann somit nicht so leicht unter die Aufsetzfläche des Zylinderfusses gelangen und die Oberfläche des Werkstücks beschädigen. Das Abhackmesser lässt sich sowohl manuell als auch durch einen mit ihm verbundenen Druckluftkolben betätigen, der seinerseits durch ein geeignetes, manuell betätigbares Tastventil auslösbar ist.Due to the independent arrangement of the chopping knife from the ram there is no danger that it will break off frequently and cause malfunctions. The empty tether is safely and reliably severed over a longer length and can therefore not easily get under the mounting surface of the cylinder base and damage the surface of the workpiece. The chopping knife can be operated both manually and by means of a compressed air piston connected to it, which in turn can be triggered by a suitable, manually actuated feeler valve.

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

Es zeigen:

  • Fig. 1 Einschlaggerät, von der Seite.
  • Fig. 2 Schnitt nach Linie 11-11 in Fig. 1, manuelle Betätigung.
  • Fig. 3 Schnitt entsprechend Fig. 2, Betätigung durch Druckluftkolben.
Show it:
  • Fig. 1 wrapping machine, from the side.
  • Fig. 2 section along line 11-11 in Fig. 1, manual operation.
  • Fig. 3 section corresponding to Fig. 2, actuation by compressed air pistons.

Bei dem in Fig. 1 gezeigten Einschlaggerät ist in einem Gehäuse 1 ein Druckschlagkolben 2 mit Schlagstössel 3 verschiebbar gelagert. Mit dem Gehäuse 1 ist ein Zylinderfuss 4 verbunden, in dessen Ausstosskanal 5 das Befestigungsmittel, also z.B. der Nagel 6, bereitgestellt ist und von dort mit dem Schlagstössel 3 in ein nicht dargestelltes Werkstück eingeschlagen werden kann. Die Nägel 6 sind durch einen Haltegurt 7 zu einem Nagelstreifen 6 verbunden und spiralig aufgerollt in einem Trommelmagazin 8 gespeichert. Von dort werden sie über einen Förderschacht 9 mittels einer Fördervorrichtung 10 dem Ausstosskanal 5 zugeführt und für den nächsten Schlag bereitgestellt.In the impact device shown in FIG. 1, a pressure impact piston 2 with impact ram 3 is slidably mounted in a housing 1. A cylinder base 4 is connected to the housing 1, in the ejection channel 5 of which the fastening means, i.e. e.g. the nail 6 is provided and from there can be driven into a workpiece, not shown, with the ram 3. The nails 6 are connected to a nail strip 6 by a holding belt 7 and are stored in a drum magazine 8 in a spiral roll. From there, they are fed to the discharge channel 5 via a conveyor shaft 9 by means of a conveyor device 10 and made available for the next stroke.

Beim Einschlagen des Nagels wird dieser vom Haltegurt 7 abgerissen, so dass von diesem noch der Rücken 11 und die aufgerissenen Haltespangen 12 übrig bleiben (siehe Fig. 2). Der Haltegurt 7 wird dabei beim nächsten Schlaghub durch die Fördervorrichtung 10 durch einen Austrittsschlitz 13 ins Freie befördert.When the nail is hammered in, it is torn off the holding belt 7, so that the back 11 and the torn holding clips 12 remain of this (see FIG. 2). The tether 7 is conveyed to the outside on the next stroke by the conveyor device 10 through an outlet slot 13.

Wie besonders Fig. 2 zeigt, ist am Zylinderfuss 4 in der Nähe von Austrittsschlitz 13 mit Schrauben 14 eine Führungshülse 15 befestigt, in der ein Abhackmesser 16 verschiebbar gelagert ist.As particularly shown in FIG. 2, a guide sleeve 15 is fastened to the cylinder base 4 in the vicinity of the outlet slot 13 with screws 14, in which a chopping knife 16 is slidably mounted.

Die Schneidkante 17 von Abhackmesser 16 bewegt sich dabei senkrecht zum Förderschacht 9 über den Austrittsschlitz 13.The cutting edge 17 of chopping knife 16 moves perpendicular to the feed shaft 9 via the outlet slot 13.

In einer Längsbohrung 18 von Abhackmesser 16 ist eine Druckfeder 19 angeordnet, die das Abhackmesser in Ruhestellung vom Austrittsschlitz 13 wegdrückt. Es wird dabei in seiner Ruhestellung von einem mit ihm verbundenen Stift 20 gehalten, der in eine Nut 21 von Führungshülse 15 eingreift.A compression spring 19 is arranged in a longitudinal bore 18 of the chopping knife 16 and pushes the chopping knife away from the outlet slot 13 in the rest position. It is held in its rest position by a pin 20 connected to it, which engages in a groove 21 of the guide sleeve 15.

Nach aussen wird die Führungshülse 15 von einem Betätigungsstift 22 überragt, mit dem das Einschlaggerät so gegen eine passende Fläche, z.B. am Werkbank oder Werkstück gestossen werden kann, dass sich das Abhackmesser 16 in Richtung Förderschacht 9 verschiebt und den leeren Haltegurt 7 abtrennt.To the outside, the guide sleeve 15 is surmounted by an actuating pin 22, with which the wrapping device thus hits a suitable surface, e.g. can be pushed against the workbench or workpiece that the chopping knife 16 moves in the direction of the conveyor shaft 9 and detaches the empty tether 7.

Wie Fig. 3 zeigt, kann bei einer weiteren Ausführungsform der Erfindung das Abhackmesser 16 mit einem Druckluftkolben 23 verbunden sein, der in einem mit der Führungshülse 24 verbundenen Druckluftzylinder 25 verschiebbar gelagert ist. Druckluftzylinder 25 ist dabei über eine Druckluftleitung 26 mit einem nicht dargestellten Tastventil verbunden, durch das nach Betätigung von Hand das Abhackmeser wieder auslösbar ist.As shown in FIG. 3, in a further embodiment of the invention the chopping knife 16 can be connected to a compressed air piston 23 which is displaceably mounted in a compressed air cylinder 25 connected to the guide sleeve 24. Compressed air cylinder 25 is connected via a compressed air line 26 to a tactile valve, not shown, by means of which the chopping knife can be triggered again after being actuated by hand.
