Description

Die Erfindung betrifft zum Eintreibmodule zum Eintreiben von miteinander mittels eines Verbindungsmittels zu einem Befestigungsmittelband verbundenen und zu einer Bandrolle aufgerollt magazinierten Befestigungsmitteln in ein Werkstück, wobei diese Eintreibmodule an eine Werkzeugbrücke montiert werden insbesondere im Rahmen industrieller Fertigung. Diese Eintreibmodule werden zum Beispiel bei der Fertigung von Fertighausmodulen angewendet.The invention relates to driving modules for driving fastening means connected to one another by means of a connecting means to form a fastener tape and rolled up into a roll of tape into a workpiece, these driving modules being mounted on a tool bridge, in particular in the context of industrial production. These drive modules are used, for example, in the manufacture of prefabricated house modules.

Bei bisher bekannten Eintreibmodulen, z.B. dem von ITW Befestigungssysteme GmbH vertriebenen "Toolmatic Serie CT550", muss die Werkzeugbrücke gestoppt werden, wenn die Befestigungsmittel im Magazin zu Neige gehen. Zudem werden oft mehrere Werkzeuge an einer Werkzeugbrücke verwendet, welche zu unterschiedlichen Zeiten befüllt werden müssen. Um die Anzahl der Stops zu minimieren werden daher oft mit einem Stop auch Module nachbefüllt, deren Magazin noch nicht ganz leer ist, was zur Folge hat, dass die dann noch im Magazin befindlichen Eintreibmittel nicht mehr verwendet werden und weggeworfen werden. Aufgabe der vorliegenden Erfindung ist es, diese Nachteile zu verbessern, insbesondere die Dauer des Maschinenstillstands bei einem Nachbefüllen von Befestigungsmitteln zu verkürzen, und weiter bevorzugt die Anzahl der notwendigen Stops zu reduzieren und möglichst alle Befestigungsmittel zu verwenden. Ein weiteres Eintreibmodul mit zwei Magazinen ist zum Beispiel aus US 4 898 316 A bekannt.With previously known drive modules, for example the "Toolmatic Series CT550" sold by ITW Fixing Systems GmbH, the tool bridge must be stopped when the fasteners in the magazine are running low. In addition, several tools are often used on a tool bridge, which have to be filled at different times. In order to minimize the number of stops, modules whose magazine is not yet completely empty are therefore often refilled with a stop, with the result that the driving agents still in the magazine are no longer used and are thrown away. The object of the present invention is to improve these disadvantages, in particular to shorten the duration of the machine standstill when refilling fasteners, and more preferably to reduce the number of necessary stops and to use all fasteners if possible. Another drive module with two magazines is off, for example U.S. 4,898,316 A known.

Die Aufgabe wird durch die unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen definiert.The problem is solved by the independent claims. Advantageous further developments are defined in the subclaims.

Hierdurch wird die Ausgabe von Befestigungsmitteln aus den Bandrollenhaltern erleichtert, d.h. ein einfacherer Transportmechanismus, der das Befestigungsmittelband von dem Magazin zum Eintreibaggregat führt, kann verwendet werden, denn es ist eine Position für die Ausgabe definiert.This facilitates the delivery of fasteners from the tape roll holders, ie a simpler transport mechanism that guides the fastener tape from the magazine to the driving unit can be used because a position for the output is defined.

Bevorzugt sind die Bandrollenhalter in die Ausgabeposition und die Reserveposition mittels einer, bevorzugt im Wesentlichen senkrecht zur Eintreibrichtung gerichteten, Verschiebung positionierbar.The tape roll holders can preferably be positioned in the dispensing position and the reserve position by means of a displacement, preferably essentially perpendicular to the driving direction.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist das Eintreibmodul einen Magazinwechselmechanismus mit einem, bevorzugt elektrisch oder pneumatisch oder hydraulisch betätigten, Magazinwechselaktor auf, mittels welchem die Bandrollenhalter in die Ausgabeposition und die Reserveposition positionierbar sind. In einem weiter bevorzugten Verfahren gemäß der Erfindung werden die Bandrollenhalter entsprechend positioniert.In a further exemplary embodiment of the present invention, the drive module has a magazine change mechanism with a magazine change actuator, preferably electrically or pneumatically or hydraulically operated, by means of which the tape roll holders can be positioned in the dispensing position and the reserve position. In a further preferred method according to the invention, the tape roll holders are positioned accordingly.

Hierdurch kann ein automatischer Wechsel zwischen den Positionen erfolgen.This enables an automatic change between the positions to take place.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist das Eintreibmodul einen Vorschubmechanismus für das Befestigungsmittelband und einen Einfädelmechanismus auf, wobei der Einfädelmechanismus eingerichtet ist, einen Einfädelvorgang durchzuführen, bei dem der Anfang des einen Befestigungsmittelbands der einen Bandrolle aus einem der beiden Bandrollenhalter in den Vorschubmechanismus überführt wird, wenn das andere Befestigungsmittelband der anderen Bandrolle aus dem anderen der beiden Bandrollenhalter zu Neige geht oder aufgebraucht ist. In einem weiter bevorzugten Verfahren gemäß der Erfindung erfolgt ein entsprechender Einfädelvorgang wenn eines der beiden Befestigungsmittelbänder zu Neige geht oder aufgebraucht ist.In a further exemplary embodiment of the present invention, the drive module has a feed mechanism for the fastener tape and a threading mechanism, the threading mechanism being set up to carry out a threading process in which the beginning of the one fastener tape of one tape roll is transferred from one of the two tape roll holders to the feed mechanism when the other fastener tape of the other roll of tape from the other of the two roll of tape holders runs out or is used up. In a further preferred method according to the invention, a corresponding threading process takes place when one of the two fastener tapes is running low or has been used up.

Hierdurch wird ein vollautomatischer Wechsel von einem Bandrollenhalter mit aufgebrauchter Bandrolle zu einem neuen Bandrollenhalter mit frischer Bandrolle ermöglicht. Somit wird die Kapazität der Befestigungsmittel, welche ohne Nutzerinteraktion und im durchgängigen Betrieb eintreibbar sind, verdoppelt.This enables a fully automatic change from a tape roll holder with an exhausted tape roll to a new tape roll holder with a fresh tape roll. Thus, the capacity of the fasteners, which can be driven in without user interaction and in continuous operation, is doubled.

Der Vorschubmechanismus ist bevorzugt eingerichtet ein in ihn eingelegtes Befestigungsmittelband mit jeder erneuten Eintreibbewegung des Wergzeugs um ein Befestigungsmittel weiter zu befördern.The feed mechanism is preferably set up with a fastener tape inserted into it with each renewed driving movement of the tool in order to advance a fastener.

Der Einfädelmechanismus weist bevorzugt ein aktorbetriebenes Zug- und/oder Schubelement, welches bevorzugt ein Schlepphaken ist, auf, welches eingerichtet ist an eines der Befestigungsmittel oder an das Verbindungsmittel am Anfang des Befestigungsmittelbands anzukoppeln, bevorzugt einzuhaken, und dieses in den Vorschubmechanismus hineinzuziehen und/oder hineinzuschieben, bevorzugt bis an das Ende des vorherigen noch in dem Vorschubmechanismus eingelegten Befestigungsmittelbands.The threading mechanism preferably has an actuator-operated pulling and / or pushing element, which is preferably a tow hook, which is set up to be coupled, preferably hooked, to one of the fastening means or to the connection means at the beginning of the fastening means band, and this into the To pull in and / or push in the advancing mechanism, preferably up to the end of the previous fastener tape still inserted in the advancing mechanism.

Bevorzugt erfolgt ein Einfädelvorgang im Anschluss an einen Positioniervorgang der Bandrollenhalter. Bevorzugt erfolgt der Einfädelvorgang im Anschluss an einen Positioniervorgang der Bandrollenhalter, welcher bevorzugt mittels des Magazinwechselmechanismus erfolgt. Es erfolgt bevorzugt das Überführen des Anfangs desjenigen Befestigungsmittelbands, welches in denjenigen Bandrollenhalter eingelegt ist, welcher zuletzt in die Ausgabeposition positioniert wurde.A threading-in process preferably takes place following a positioning process for the tape roll holder. The threading process preferably takes place following a positioning process for the tape roll holder, which is preferably carried out by means of the magazine changing mechanism. The transfer of the beginning of that fastener tape which is inserted into that tape roll holder which was last positioned in the dispensing position takes place.

Bevorzugt weist das Eintreibmodul, bevorzugt im Bereich des Vorschubmechanismus, einen Sensor, bevorzugt einen Induktionssensor auf, mittels welchem das Durchlaufen des letzten Befestigungsmittels eines Befestigungsmittelbands detektiert wird.The driving module preferably has a sensor, preferably an induction sensor, preferably in the area of the advancing mechanism, by means of which the passage of the last fastening means of a fastening means band is detected.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist jeder der zwei Bandrollenhalter einen Ausgangsabschnitt auf und diese Ausgangsabschnitte weisen jeweils eine, bevorzugt rücklaufgesicherte, Halterung auf, in welche der Anfang des Befestigungsmittelbands einlegbar ist. In einem weiter bevorzugten Verfahren gemäß der Erfindung wird der Anfang des Befestigungsmittelbands entsprechend eingelegt.In a further exemplary embodiment of the present invention, each of the two tape roll holders has an output section and these output sections each have a retainer, preferably non-return, into which the beginning of the fastener tape can be inserted. In a further preferred method according to the invention, the beginning of the fastener tape is inserted accordingly.

Hierdurch ist das Befestigungsmittelband in einem neu aufgefüllten Bandrollenhalter in eine vordefinierte Position bringbar, aus der der Einfädelmechanismus dann den Anfang des Bands übernehmen kann.As a result, the fastener tape in a newly filled tape roll holder can be brought into a predefined position from which the threading mechanism can then take over the beginning of the tape.

Die Halterung weist als Rücklaufsicherung bevorzugt einen Schnappkeil auf, der bevorzugt manuell lösbar ist.As a backstop, the holder preferably has a snap wedge, which can preferably be released manually.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist der Vorschubmechanismus mehrere entlang der Vorschubrichtung verteilte Vorschubelemente und mehrere entlang der Vorschubrichtung verteilte Rückhalteelemente auf. In einem weiter bevorzugten Verfahren gemäß der Erfindung wird das Befestigungsmittelband mit einem entsprechenden Vorschubmechanismus, bevorzugt mit jedem Eintreibvorgang, befördert.In a further exemplary embodiment of the present invention, the advancing mechanism has a plurality of advancing elements distributed along the advancing direction and a plurality of retaining elements distributed along the advancing direction. In a further preferred method according to the invention, the fastener tape is conveyed with a corresponding feed mechanism, preferably with each driving-in process.

Hierdurch können das auslaufende, verbrauchte, und das einlaufende neue Befestigungsmittelband, die folglich nicht zusammenhängen, gemeinsam mit gleicher Geschwindigkeit zuverlässig transportiert werden.As a result, the expiring, used, and incoming new fastener tape, which are consequently not connected, can be reliably transported together at the same speed.

Die Vorschubelemente sind bevorzugt in Vorschubrichtung mittels eines Aktors hin- und her verschiebbare, bevorzugt federgelagerte, Schnappkeile.The feed elements are preferably spring-loaded snap wedges that can be moved back and forth in the feed direction by means of an actuator.

Die Rückhalteelemente sind bevorzugt bzgl. der Vorschubrichtung feststehende und bevorzugt federgelagerte Schnappkeile.The retaining elements are preferably fixed and preferably spring-mounted snap wedges with respect to the feed direction.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung sind die Vorschubelemente und/oder die Rückhalteelemente an einem Trägerteil gehalten, wobei das Trägerteil verschwenkbar ist, um ein in dem Vorschubmechanismus eingelegtes Befestigungsmittelband zugänglich oder leichter zugänglich zu machen.In a further exemplary embodiment of the present invention, the advancing elements and / or the retaining elements are held on a carrier part, the carrier part being pivotable in order to make a fastener tape inserted in the advancing mechanism accessible or more easily accessible.

Das Trägerteil ist bevorzugt über ein Scharnier an dem Eintreibmodul schwenkbar gelagert.The carrier part is preferably mounted pivotably on the driving module via a hinge.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung weist das Eintreibmodul einen Aggregatträger auf und das Eintreibaggregat ist an dem Aggregatträger angeordnet und das Eintreibaggregat ist als solches mittels eines Heranführantriebs an das jeweilige Werkstück in einer Heranführbewegung heranführbar, bevorzugt andrückbar, und hierfür über eine Aggregatführung an dem Aggregatträger in der Eintreibrichtung verschiebbar geführt.In a further exemplary embodiment of the present invention, the driving module has a unit carrier and the driving unit is arranged on the unit carrier and the driving unit as such can be brought up to the respective workpiece in a moving movement by means of a drive drive, preferably pressed, and for this purpose on the unit carrier via a unit guide guided displaceably in the driving direction.

Der Heranführantrieb ist bevorzugt als Keilantrieb ausgeführt, d.h. dass sich mittels der Verschiebung eines Keils senkrecht zur Eintreibrichtung, wobei sich der Keil oberhalb des Eintreibaggregats befindet, das Eintreibaggregat heben und senken lässt.The approach drive is preferably designed as a wedge drive, i.e., by moving a wedge perpendicular to the driving direction, with the wedge located above the driving unit, the driving unit can be raised and lowered.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung ist das Magazin derart an den Aggregatträger angekoppelt, dass eine in dem Magazin eingelegte Bandrolle im Wesentlichen, bevorzugt vollständig, von der Heranführbewegung des Eintreibaggregats entkoppelt ist.In a further exemplary embodiment of the present invention, the magazine is coupled to the unit carrier in such a way that a tape roll inserted in the magazine is essentially, preferably completely, decoupled from the approach movement of the driving unit.

Hierdurch wird es möglich ein größeres Magazin mit einer höheren Kapazität an Befestigungsmitteln zu verwenden. Durch die Entkopplung wird das Gewicht der Befestigungsmittel nicht jedes Mal beim Heranführen des Eintreibaggregats mitbewegt, was somit Energie einspart und die Komponenten weniger belastet, so dass ein höheres Magazingewicht aufgrund erhöhter Magazinkapazität verkraftet werden kann.This makes it possible to use a larger magazine with a higher capacity of fasteners. By decoupling the weight of the Fastening means are not moved along every time the driving unit is brought up, which thus saves energy and puts less stress on the components, so that a higher magazine weight can be withstood due to the increased magazine capacity.

Diese Ausführung ist bereits auch mit einem ansonsten gewöhnlichen Magazin für aufgerollte Befestigungsmittelbänder (d.h. ohne mehrere Bandrollenhalter) geeignet, die Kapazität des Magazins ohne große negative Nebeneffekte zu erhöhen und somit die Anzahl an Stops zum Nachbefüllen des Magazins zu reduzieren. Es ist daher nicht notwendig, dass das Magazin mindestens zwei Bandrollenhalter zur Aufnahme jeweils mindestens einer Bandrolle aufweist; und in entsprechend breiter beanspruchter Form kann insbesondere diese Ausführung auch Gegenstand einer Teilanmeldung sein, wobei es unbenommen bleibt auch andere Ausführungsformen als Teilanmeldung zu verfolgen.This design is already suitable with an otherwise common magazine for rolled up fastener tapes (i.e. without multiple tape reel holders) to increase the capacity of the magazine without major negative side effects and thus to reduce the number of stops for refilling the magazine. It is therefore not necessary for the magazine to have at least two tape roll holders for receiving at least one tape roll each; and in a correspondingly broader claimed form, this embodiment in particular can also be the subject of a divisional application, although other embodiments as a divisional application also remain open.

Unter im Wesentlichen entkoppelt wird bevorzugt verstanden, dass der Kern der Rolle oder der Rollenmittelpunkt statisch ist, und somit auch der noch aufgerollte Teil der Rolle, während sich das abgerollte Bandstück mitbewegen kann.Essentially decoupled is preferably understood to mean that the core of the roll or the roll center point is static, and thus also the part of the roll that is still rolled up, while the unrolled piece of tape can move with it.

In einem weiteren Ausführungsbeispiel der vorliegenden Erfindung ist der Ausgangsabschnitt des Magazins verschiebbar gegenüber dem Befestigungsabschnitt des Magazins gelagert, bevorzugt parallel zur Heranführbewegung verschiebbar gelagert.In a further exemplary embodiment of the present invention, the output section of the magazine is mounted displaceably with respect to the fastening section of the magazine, preferably mounted displaceably parallel to the approach movement.

Hierdurch wird es möglich, eine zuverlässige Herausführung des Befestigungsmittelbands zu dem relativ sich zu dem Magazin bewegten Eintreibaggregat bewirkt. Der Ausgangsabschnitt des Magazins oder des Bandrollenhalters ist bevorzugt derart mit dem Eintreibaggregat gekoppelt, dass sich der Ausgangsabschnitt mit der Heranführbewegung parallel mitbewegt. Insbesondere beim Vorhandensein eines Einfädelmechanismus ist es von Vorteil, wenn der Ausgangsabschnitt des Magazins aufgrund der Verschiebbarkeit derart ortsfest gegenüber Vorschubmechanismus und Eintreibaggregat angeordnet ist, da dann ein zuverlässiger automatischer Übergang zu einer frischen Bandrolle auf dem anderen Bandrollenhalter erfolgen kann.This makes it possible to reliably lead the fastener tape out to the driving unit which is moving relative to the magazine. The output section of the magazine or of the tape roll holder is preferably coupled to the driving unit in such a way that the output section moves in parallel with the approach movement. Particularly when a threading mechanism is present, it is advantageous if the output section of the magazine is arranged so that it is stationary in relation to the feed mechanism and driving unit due to the displaceability, so that a reliable automatic transition to a fresh tape roll on the other tape roll holder can then take place.

Das Eintreibmodul 1 gemäß Fig. 1a ist ein Eintreibmodul 1 zum Eintreiben von miteinander mittels eines Verbindungsmittels 103 zu einem Befestigungsmittelband 102 verbundenen und zu einer Bandrolle 101, 101' aufgerollt magazinierten Befestigungsmitteln 100 in ein Werkstück 200. Es weist ein Eintreibaggregat 20 und einen Montageabschnitt 12 zur Montage des Eintreibmoduls 1 an eine Werkzeugbrücke 300 auf. Das Eintreibaggregat 20 weist einen Eintreibantrieb 21 auf, der über einen in Eintreibrichtung 22 verschiebbaren Eintreibstempel 23 mit einer Eintreibkraft auf das jeweils einzutreibende Befestigungsmittel 100 wirkt. An das Eintreibmodul 1 ist ein Magazin 30 befestigt, welches mindestens einen Ausgangsabschnitt 33, 33' aufweist, über welchen das Befestigungsmittelband 102 von der Bandrolle 101 aus dem Magazin 30 herausführbar ist. Das Magazin 30 weist mindestens einen Befestigungsabschnitt 32 zur Befestigung des Magazins 30 oder Teilen davon an das Eintreibmodul 1 auf. Das Magazin 30 weist zudem zwei Bandrollenhalter 31, 31' zur Aufnahme jeweils einer Bandrolle 101, 101' auf. Die Befestigungsmittel sind hier Nägel, die mit einem Plastikgurt verbunden sind.The driving module 1 according to Fig. 1a is a driving module 1 for driving fastening means 100 connected to one another by means of a connecting means 103 to form a fastening means tape 102 and rolled up into a tape roll 101, 101 'into a workpiece 200. It has a driving unit 20 and a mounting section 12 for mounting the Drive module 1 to a tool bridge 300. The driving unit 20 has a driving drive 21 which acts with a driving force on the fastening means 100 to be driven in via a driving punch 23 which is displaceable in the driving direction 22. A magazine 30 is fastened to the drive module 1 and has at least one output section 33, 33 ′, via which the fastener tape 102 can be guided out of the magazine 30 from the tape roll 101. The magazine 30 has at least one fastening section 32 for fastening the magazine 30 or parts thereof to the driving module 1. The magazine 30 also has two tape roll holders 31, 31 'for receiving one tape roll 101, 101' each. The fasteners here are nails that are connected with a plastic strap.

Das Eintreibmodul 1 gemäß Fig. 1b weist zusätzlich zu dem aus Fig. 1a einen Aggregatträger 10 auf und das Eintreibaggregat 20 ist an dem Aggregatträger 10 angeordnet. Das Eintreibaggregat 20 ist als solches mittels eines Heranführantriebs 40 an das jeweilige Werkstück 200 in einer Heranführbewegung heranführbar. Hierfür ist es über eine Aggregatführung 11 an dem Aggregatträger 10 in der Eintreibrichtung 22 verschiebbar geführt. Das Magazin 30 ist derart an den Aggregatträger 10 angekoppelt, dass eine in dem Magazin 30 eingelegte Bandrolle 101 im Wesentlichen von der Heranführbewegung des Eintreibaggregats 20 entkoppelt ist. Es ist hier nicht notwendig, dass das Magazin 30 mindestens zwei Bandrollenhalter 31 zur Aufnahme jeweils mindestens einer Bandrolle aufweist, jedoch ist dies sehr vorteilhaft.The driving module 1 according to Figure 1b indicates in addition to the Fig. 1a an assembly carrier 10 and the driving assembly 20 is arranged on the assembly carrier 10. The driving unit 20 as such can be brought up to the respective workpiece 200 by means of a feed drive 40 in a feed movement. For this purpose, it is guided displaceably in the driving direction 22 via an assembly guide 11 on the assembly carrier 10. The magazine 30 is coupled to the unit carrier 10 in such a way that a tape roll 101 inserted in the magazine 30 is essentially decoupled from the approach movement of the driving unit 20. It is not necessary here for the magazine 30 to have at least two tape roll holders 31 for receiving at least one tape roll each, but this is very advantageous.

Das in Fig. 2a-6c gezeigte Ausführungsbeispiel weist zudem insbesondere folgende Merkmale auf.This in Figures 2a-6c The embodiment shown also has the following features in particular.

Die Bandrollenhalter 31, 31' sind als Magazinkassetten ausgeführt und jede der zwei Magazinkassetten weist einen Befestigungsabschnitt 32, 32' auf. Sie sind von dem Eintreibmodul 1 getrennt voneinander abkoppelbar von dem Eintreibmodul 1. Das Eintreibmodul 1 weist für jede Kassette 31, 31' eine Koppelschiene 13, 13' (Fig. 3a) auf, in welche eine entsprechende Koppelschiene 36 (Fig. 4b) der jeweiligen Kassette 31, 31' eingesteckt wird, um die Kassette 31, 31' anzukoppeln. Die Bandrollenhalter 31, 31' sind jeweils alternierend in eine Ausgabeposition, in welcher Befestigungsmittel von der auf dem Bandrollenhalter 31, 31' gehalterten Bandrolle 101, 101' an das Eintreibaggregat 20 abgegeben werden, und eine Reserveposition positionierbar. Die hierfür notwendige Verschieberichtung ist in Fig. 2a und 2b mit einem Doppelpfeil angedeutet und im Wesentlichen senkrecht zur Eintreibrichtung 22 gerichtet. Das Eintreibmodul 1 weist einen Magazinwechselmechanismus 50 mit einem pneumatisch betätigten Magazinwechselaktor 51 auf (Fig. 3a), mittels welchem die Bandrollenhalter 31, 31' in die Ausgabeposition und die Reserveposition positionierbar sind. Das Eintreibmodul 1 weist außerdem einen Vorschubmechanismus 70 für das Befestigungsmittelband 102 und einen Einfädelmechanismus 60 auf. Der Einfädelmechanismus 60 ist eingerichtet, einen Einfädelvorgang durchzuführen, bei dem der Anfang des einen Befestigungsmittelbands 102, 102' der einen Bandrolle 101, 101' aus einem der beiden Bandrollenhalter 31, 31' in den Vorschubmechanismus 70 überführt wird, wenn das andere Befestigungsmittelband 102, 102' der anderen Bandrolle 101, 101' aus dem anderen der beiden Bandrollenhalter 31, 31' zu Neige geht oder aufgebraucht ist.The tape roll holders 31, 31 'are designed as magazine cassettes and each of the two magazine cassettes has a fastening section 32, 32'. They can be decoupled from the driving module 1 separately from the driving module 1. The driving module 1 has a coupling rail 13, 13 'for each cassette 31, 31' ( Fig. 3a ), in which a corresponding coupling rail 36 ( Figure 4b ) the respective cassette 31, 31 'is inserted in order to couple the cassette 31, 31'. The tape roll holders 31, 31 'can each be positioned alternately in a dispensing position, in which fastening means from the tape roll 101, 101' held on the tape roll holder 31, 31 'to the driving unit 20, and a reserve position. The necessary for this Shift direction is in Figures 2a and 2b indicated by a double arrow and directed essentially perpendicular to the driving direction 22. The driving module 1 has a magazine change mechanism 50 with a pneumatically operated magazine change actuator 51 ( Fig. 3a ), by means of which the tape roll holders 31, 31 'can be positioned in the dispensing position and the reserve position. The driving module 1 also has an advance mechanism 70 for the fastener tape 102 and a threading mechanism 60. The threading mechanism 60 is set up to carry out a threading process in which the beginning of one fastener tape 102, 102 'of one tape roll 101, 101' is transferred from one of the two tape roll holders 31, 31 'to the feed mechanism 70 when the other fastener tape 102, 102 'of the other tape roll 101, 101' from the other of the two tape roll holders 31, 31 'is running out or has been used up.

In Fig. 3a ist auch gut zu sehen, dass in dieser Ausführung der Heranführantrieb 40 als Keilantrieb ausgeführt ist.In Fig. 3a it can also be clearly seen that in this embodiment the approach drive 40 is designed as a wedge drive.

In Fig. 4a ist gut zu sehen, dass die Bandrollenhalterungen 31, 31' eine Zentriereinheit 37 mit drei kreisförmig angeordneten, radial verschiebbaren Rollen, aufweisen, auf welche die Bandrolle drehbar aufgesetzt werden kann. Die Bandrollenhalterungen 31, 31' weisen zudem einen Deckel auf, welcher bevorzugt in verschiedenen Höhen an einem Deckelhalter 34 einrastbar ist, um an verschiedene Nagellängen angepasst zu werden. Die Bandrollenhalterungen 31, 31' weisen zudem ein federvorgespanntes Leitblech 35 auf, welches ein ordnungsgemäßes Abwickeln der Bandrolle gewährleisten soll. Zudem weist jeder der zwei Bandrollenhalter 31, 31' einen Ausgangsabschnitt 33, 33' auf. Diese Ausgangsabschnitte 33, 33' weisen jeweils eine rücklaufgesicherte Halterung 33.1 auf, in welche der Anfang des Befestigungsmittelbands 102 einlegbar ist. Die Halterung 33.1 weist als Rücklaufsicherung einen Schnappkeil auf, der manuell lösbar ist.In Figure 4a it can be clearly seen that the tape reel holders 31, 31 'have a centering unit 37 with three circularly arranged, radially displaceable rollers on which the tape reel can be rotatably placed. The tape roll holders 31, 31 ′ also have a cover which can preferably be latched onto a cover holder 34 at different heights in order to be adapted to different nail lengths. The tape roll holders 31, 31 'also have a spring-loaded guide plate 35, which is intended to ensure that the tape roll is properly unwound. In addition, each of the two tape roll holders 31, 31 'has an output section 33, 33'. These output sections 33, 33 'each have a non-return holder 33.1 into which the beginning of the fastener tape 102 can be inserted. The holder 33.1 has a snap wedge as a backstop which can be released manually.

In Fig. 4c und 4d ist gut zu sehen, dass der Ausgangsabschnitt 33, 33' der Bandrollenhalterungen 31, 31' verschiebbar gegenüber dem Befestigungsabschnitt 32, 32' der Bandrollenhalterungen 31, 31' gelagert ist und parallel zur Heranführbewegung verschiebbar gelagert ist. Dies ist durch Vergleich der beiden Figuren leicht ersichtlich.In Figures 4c and 4d it can be clearly seen that the output section 33, 33 'of the tape roll holders 31, 31' is mounted displaceably with respect to the fastening section 32, 32 'of the tape roll holders 31, 31' and is mounted displaceably parallel to the approach movement. This can be easily seen by comparing the two figures.

In Fig. 5a und 5b ist gut sehen, dass der Einfädelmechanismus 60 bevorzugt einen aktorbetriebenen Schlepphaken 61 aufweist. Dieser ist eingerichtet ist an eines der Befestigungsmittel 100 am Anfang des Befestigungsmittelbands 102 einzuhaken, und dieses in den Vorschubmechanismus 70 hineinzuziehen und/oder hineinzuschieben bis an das Ende des vorherigen noch in dem Vorschubmechanismus 70 eingelegten Befestigungsmittelbands. Hierfür weist der Ausgangabschnitt 33, 33' der Kassetten 31, 31' eine Nut 38 im Bereich der rücklaufgesicherten Halterung 33.1 auf (siehe Fig. 4b, durch welche der Haken 61 hindurch Zugriff auf das Befestigungsmittel 100 hat. Der Schlepphaken 61 ist an einem Linearaktor gelagert.In Figures 5a and 5b it can be clearly seen that the threading mechanism 60 preferably has an actuator-operated tow hook 61. This is set up to be hooked onto one of the fastening means 100 at the beginning of the fastening means band 102, and to pull it into the feed mechanism 70 and / or push it into the end of the previous fastening means band which was still inserted in the feed mechanism 70. For this purpose, the output section 33, 33 'of the cassettes 31, 31' has a groove 38 in the area of the non-return mount 33.1 (see FIG Figure 4b through which the hook 61 has access to the fastener 100. The tow hook 61 is mounted on a linear actuator.

In Fig. 6a-6c ist gut zu sehen, dass der Vorschubmechanismus 70, welcher auf der anderen Seite des Schlepphakens 61 angeordnet ist (siehe Fig. 5a/b, mehrere entlang der Vorschubrichtung verteilte Vorschubelemente 71, 71', 71" und mehrere entlang der Vorschubrichtung verteilte Rückhalteelemente 72, 72', 72" aufweist. Die Vorschubelemente 71, 71', 71" sind in Vorschubrichtung mittels eines Vorschubaktors 74 hin- und her verschiebbare, federgelagerte, Schnappkeile.
