Description

Die Erfindung bezieht sich auf ein Einschlaggerät gemäss Oberbegriff von Anspruch 1.The invention relates to a wrapping device according to the preamble of claim 1.

Bei der Befestigung von Lochblechen und Balkenschuhen an Balken sollen Nägel oder dgl. mittels zumeist druckluftbetriebenen Einschlaggeräten durch bereits vorgestanzte Löcher in den Blechen eingeschlagen werden. Zum bequemen Ausrichten des Einschlaggerätes auf diese Löcher wird die überstehende Nagelspitze des einzuschlagenden Nagels in das jeweilige Loch eingeführt. Dabei muss jedoch auch sicher verhindert werden, dass der Nagel beim Aufsetzen zurückweicht.When fastening perforated plates and beam shoes to beams, nails or the like are to be driven through pre-punched holes in the plates by means of usually compressed-air driven impact devices. For easy alignment of the driving tool on these holes, the protruding nail tip of the nail to be driven is inserted into the respective hole. However, it must also be prevented that the nail retreats when it is put on.

Aus der US-A 4 049 181 ist es bekannt, den einzuschlagenden Nagel im Führungsschacht durch Permanentmagnete festzuhalten. Dabei wird jedoch der Nagel lediglich am Herausfallen gehindert, ein Zurückweichen beim Aufsetzen des Gerätes wäre trotzdem möglich und somit ist diese Vorrichtung nicht dazu geeignet, das Einschlaggerät auf vorgestanzte Löcher einwandfrei und schnell auszurichten.From US-A 4 049 181 it is known to hold the nail to be driven in the guide shaft by means of permanent magnets. However, the nail is only prevented from falling out, a retraction when placing the device would still be possible and thus this device is not suitable for aligning the impacting device correctly and quickly with pre-punched holes.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Einschlaggerät der eingangs genannten Art zu schaffen, bei dem bei möglichst einfacher konstruktiver und funktioneller Ausführung ein rasches Ausrichten des Einschlaggerätes mittels der Nagelspitze auf das vorgestanzte Loch möglich ist.The invention is therefore based on the object of providing a wrapping device of the type mentioned at the beginning, in which, with the simplest possible constructional and functional design, rapid alignment of the wrapping device by means of the nail tip onto the pre-punched hole is possible.

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

Durch diese erfindungsgemässe Ausführung ist es auf überraschend einfache Weise möglich, den einzuschlagenden Nagel so festzuhalten, dass sich das Einschlaggerät sicher auf das vorgestanzte Loch ausrichten lässt.Through this embodiment according to the invention, it is possible in a surprisingly simple way to hold the nail to be driven in such that the driving tool can be safely aligned with the pre-punched hole.

Werden erfindungsgemäss mehrere Nuten mit entsprechenden Anschlagflächen übereinander angeordnet, dann lassen sich mit demselben Einschlaggerät alle wichtigen Nagellängen verarbeiten. Das Gerät ist also vielseitig verwendbar und weist auch die für eine Baustelle entscheidende Robustheit auf.If several grooves with corresponding stop surfaces are arranged one above the other according to the invention, then all important nail lengths can be processed with the same driving tool. The device is therefore versatile and also has the robustness that is decisive for a construction site.

Zur Aufnahme von verschiedenen Nagellängen im Magazin sind in diesem übereinanderliegende Führungsnuten vorgesehen, in die die Nagelköpfe eintreten können. Zum leichten Einführen der Nagelstreifen ist im Magazin eine nach oben offene Einführöffnung vorgesehen, in die der Nagelstreifen eingesteckt wird. Das Magazin ist geneigt zum Ausstosskanal angeordnet und der Nagelstreifen gleitet so in Richtung Ausstosskanal, dass die Nagelspitzen auf einer Gleitrinne aus Stahlblech aufliegen und die Nagelköpfe in die entsprechenden Führungsnuten eintreten.To accommodate different nail lengths in the magazine, superimposed guide grooves are provided in the magazine, into which the nail heads can enter. For easy insertion of the nail strips, an upwardly open insertion opening is provided in the magazine, into which the nail strips are inserted. The magazine is inclined to the ejection channel and the nail strip slides in the direction of the ejection channel so that the nail tips rest on a slide channel made of sheet steel and the nail heads enter the corresponding guide grooves.

Im folgenden ist ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben.An exemplary embodiment of the invention is described in more detail below with reference to the drawings.

Es zeigen:

  • Fig. 1 Einschlaggerät von der Seite, teilweise geschnitten.
  • Fig. 2 Schnitt nach Linie 11-11 in Fig. 1
  • Fig. 3 Führungsfuss, teilweise, von vorne
Show it:
  • Fig. 1 wrapping machine from the side, partially cut.
  • 2 section along line 11-11 in Fig. 1st
  • Fig. 3 guide foot, partially, from the front

Das in Fig. 1 gezeigte Einschlaggerät dient zum Einschlagen von Nägeln 1 oder dgl., die durch Kunststoffgurte 2 zu einem Nagelstreifen 3 miteinander verbunden sind. Anstelle von Nägeln können natürlich auch Schraubnägel, Schrauben, Stifte oder andere Befestigungsmittel mit dem erfindungsgemässen Einschlaggerät verarbeitet werden. Das Einschlaggerät wird in bekannter Weise mit Druckluft betrieben und weist ein Gehäuse 4 und ein Magazin 5 zur Aufnahme des Nagelstreifens 3 auf.The driving device shown in FIG. 1 is used for driving nails 1 or the like, which are connected to one another by plastic belts 2 to form a nail strip 3. Instead of nails, screw nails, screws, pins or other fasteners can of course also be processed with the driving tool according to the invention. The wrapping device is operated in a known manner with compressed air and has a housing 4 and a magazine 5 for receiving the nail strip 3.

Am Gehäuse 4 ist ein Führungsfuss 6 befestigt, in dessen Ausstosskanal 7 der druckluftbetriebene Schlagstössel 8 auf den einzuschlagenden Nagel 1 einwirkt und diesen durch ein vorgestanztes Loch 9 im Blech 10 in den Balken 11 eintreibt.On the housing 4, a guide foot 6 is fastened, in the ejection channel 7 of which the air-powered ram 8 acts on the nail 1 to be driven in and drives it through a pre-punched hole 9 in the plate 10 into the beam 11.

Im Magazin 5 wird der Nagelstreifen 3 durch einen Magazinschieber 12, an dem eine Feder 13 angreift, in Richtung Ausstosskanal 7 gedrückt. Der Kopf 14 des ersten einzuschlagenden Nagels 1 schiebt sich dabei in Richtung von Wand 15 von Ausstosskanal 7, die dem Führungsschacht 16 von Magazin 5 gegenüberliegt. In der Wand 15 befinden sich übereinanderliegende Nuten 17, die nach oben durch Anschlagflächen 18 begrenzt sind, die sich senkrecht zum Ausstosskanal 7 erstrecken. Nach unten gehen die Nuten 17 mit schrägen Flächen 19 in den Ausstosskanal 7 über.In the magazine 5, the nail strip 3 is pressed in the direction of the ejection channel 7 by a magazine slide 12, on which a spring 13 engages. The head 14 of the first nail 1 to be driven pushes in the direction of the wall 15 of the ejection channel 7, which lies opposite the guide shaft 16 of the magazine 5. In the wall 15 there are grooves 17 one above the other, which are delimited at the top by stop surfaces 18 which extend perpendicular to the ejection channel 7. At the bottom, the grooves 17 merge into the ejection channel 7 with inclined surfaces 19.

Im Magazin 5 sind Führungsnuten 20 vorgesehen (siehe auch Fig. 2), in denen die Köpfe 14 der Nägel 1 geführt werden. Diese Führungsnuten 20 fluchten mit den Nuten 17 im Ausstosskanal 7. Das Magazin 5 ist nach oben abgedeckt, weist jedoch hinter dem Gehäuse 4 eine Einführöffnung 21 auf, durch die der Nagelstreifen 3 eingeführt werden kann. Die Spitzen der Nägel 1 gelangen dabei auf eine Gleitrinne 22 auf Stahlblech, die im Magazin 5 federnd befestigt ist. Da das Magazin 5 schräg zum Führungsfuss 6 angeordnet ist, gleitet der Nagelstreifen 3 in Richtung Ausstosskanal 7, wobei die Köpfe 14 der Nägel 1 in die jeweiligen Führungsnuten 20 gelangen.Guide grooves 20 are provided in the magazine 5 (see also FIG. 2), in which the heads 14 of the nails 1 are guided. These guide grooves 20 are aligned with the grooves 17 in the ejection channel 7. The magazine 5 is covered at the top, but has an insertion opening 21 behind the housing 4 through which the nail strip 3 can be inserted. The tips of the nails 1 arrive on a slide channel 22 on sheet steel, which is resiliently fastened in the magazine 5. Since the magazine 5 is arranged obliquely to the guide foot 6, the nail strip 3 slides in the direction of the ejection channel 7, the heads 14 of the nails 1 entering the respective guide grooves 20.

Im Ausstosskanal 7 legt sich dann der Kopf 14 des ersten Nagels 1 so in die der Führungsnut 20 gegenüberliegende Nut 17, dass er sich unterhalb einer Anschlagfläche 18 befindet. Das Magazin 5 ist so am Führungsfuss 6 angeordnet, dass die Spitze des ersten Nagels 1 die Aufsetzfläche 23 des Führungsfusses 6 um 2,5 bis 3 mm überragt.The head 14 of the first nail 1 then lies in the ejection channel 7 in the groove 17 opposite the guide groove 20 such that it is located below a stop surface 18. The magazine 5 is arranged on the guide foot 6 in such a way that the tip of the first nail 1 projects 2.5 to 3 mm beyond the mounting surface 23 of the guide foot 6.

Zum Ausrichten des Einschlaggerätes auf ein Loch 9 von Blech 10 wird die Spitze von Nagel 1 in das Loch eingeführt. Ein Zurückweichen von Nagel 1 ist nicht möglich, da er einerseits durch die Anschlagfläche 18 und andererseits durch den Kopf des nachfolgenden Nagels festgehalten wird, da Nägel 1 in bekannter Weise stufenförmig miteinander verbunden sind. Nach dem Einschlagen des ersten Nagels 1 verschiebt Magazinschieber 12 den ganzen Nagelstreifen 3 so in Richtung Wand 15, dass der Kopf des nächsten Nagels wieder in die Nut 17 gelangt.To align the wrapping device with a hole 9 in sheet metal 10, the tip of nail 1 is inserted into the hole. A retraction of nail 1 is not possible because it is held on the one hand by the stop surface 18 and on the other hand by the head of the following nail, since nails 1 are connected to one another in a step-like manner in a known manner. After the first nail 1 has been driven in, the magazine pusher 12 moves the entire nail strip 3 in the direction of the wall 15 in such a way that the head of the next nail reaches the groove 17 again.

Bei einer vorteilhaften Ausführungsform der Erfindung gemäss Fig. 1 und 3 ist der Führungsfuss 6 an seinem der Aufsetzfläche 23 zugewandten Ende durch eine nach oben verlaufende Abschrägung 24 durchbrochen. Es ergibt sich damit eine Sichtöffnung 25, durch die der Bedienungsmann die Spitze von Nagel 1 einwandfrei erkennen kann und somit in der Lage ist, diese Nagelspitze ohne Schwierigkeit in das gewünschte Loch 9 einzuführen.In an advantageous embodiment of the invention according to FIGS. 1 and 3, the guide foot 6 is on its contact surface 23 End broken by an upward bevel 24. This results in a viewing opening 25 through which the operator can correctly recognize the tip of nail 1 and is therefore able to insert this nail tip into the desired hole 9 without difficulty.
