Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung einer Verriegelung bei aus Metall bestehenden, gewölbten Rolladenlamellen gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a device for producing a lock in existing metal arched roller shutter slats according to the preamble of the main claim.

Derartige Verriegelungen sind im Stand der Technik bekannt und haben die Aufgabe, dafür Sorge zu tragen, dass sich die Rolladenstäbe bzw. Rolladenlamellen in Richtung ihrer Längsachse nicht ungewollt gegeneinander verschieben können.Such locks are known in the art and have the task of ensuring that the shutter slats or shutter slats in the direction of their longitudinal axis can not move unintentionally against each other.

Bei der Konfektionierung großer Rolladenpanzer erfolgt das Einsetzen der Riegelstifte und die Bildung des Panzers durch entsprechend ausgebildete Maschinen, siehe beispielsweise EP-A-0 634 558. Bei kleineren Betrieben und insbesondere sehr individuell ausgebildeten Rolladenpanzern erfolgt das Herstellen der Verriegelung bisher von Hand und ist damit arbeitsaufwendig und beinhaltet Ungenauigkeiten, die dazu führen können, dass die Rolläden insbesondere bei großer Länge des Rolladenpanzers nicht dicht schließen.When assembling large roller shutter armor, the insertion of the locking pins and the formation of the tank is carried out by appropriately trained machines, see for example EP-A-0 634 558. For smaller operations and in particular very individually designed roller shutter armor, the locking is done by hand and is so far laborious and contains inaccuracies that can cause the blinds close especially in large length of the roller shutter not tight.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Gerät zu schaffen, das dem Handwerker bzw. dem Rolladenbauer die Möglichkeit gibt, das Einsetzen des Verriegelungsstiftes und das Herstellen der Ausnehmung bei gleichbleibender Qualität maschinell durchzuführen.The invention is therefore an object of the invention to provide a device that gives the craftsman or the shutter manufacturer the ability to mechanically perform the insertion of the locking pin and the manufacture of the recess while maintaining the same quality.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This problem underlying the invention is achieved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen erläutert.Advantageous embodiments of the invention are explained in the subclaims.

Mit anderen Worten ausgedrückt wird eine Vorrichtung vorgeschlagen, die sich im wesentlichen dadurch kennzeichnet, dass auf einem Träger eine Werkzeugplatte angeordnet ist, die vorzugsweise auswechselbar ist, d. h. gegen unterschiedliche Abmessungen aufweisende Werkzeugplatten ausgetauscht werden kann. Auf dieser Werkzeugplatte oder auch auf dem Träger ist eine Trenneinrichtung zur Herstellung der Ausnehmung und ein Schneidaggregat zur Herstellung einer Schrägfläche am äußeren Rand der Lippe des Aufnahmelängsrandes der Rolladenlamelle vorgesehen. Der Träger weist weiterhin eine Führung für eine Rolladenlamelle auf, die bei Einschieben in die Werkzeugplatte Pneumatikzylinder und die dafür erforderlichen Ventilsteuerungen in Gang setzt, um die Trenneinrichtung, das Schneidaggregat und einen Nageler betätigt, wobei der Nageler den Riegelstift in der der Ausnehmung gegenüberliegenden Seite des Rolladenstabes einschlägt.In other words, a device is proposed which is essentially characterized in that a tool plate is arranged on a carrier, which is preferably replaceable, d. H. can be exchanged against different dimensions having tool plates. On this tool plate or on the support a separating device for producing the recess and a cutting unit for producing an inclined surface on the outer edge of the lip of the receiving longitudinal edge of the roller shutter slat is provided. The carrier also has a guide for a roller shutter slat, which, when inserted into the tool plate, actuates pneumatic cylinders and the necessary valve controls, actuates the separating device, the cutting unit and a nailer, the nailer actuating the locking pin in the opposite side of the recess Roller shutter bar strikes.

Bei einer ersten Ausführungsform dieses erfindungsgemäßen Vorschlages wird eine Stanze als Trenneinrichtung eingesetzt, um die Ausnehmung herzustellen, wobei diese Stanze von oben auf die mit ihrer konkav gewölbten Seite nach unten in der Führung liegende Rolladenlamelle einwirkt. Als Schneidaggregat wird bei dieser Ausführungsform ein Messer eingesetzt, das die Schrägfläche am äußeren Rand der Lippe des Aufnahmelängsrandes der Rolladenlamelle herstellt.In a first embodiment of this proposal according to the invention, a punch is used as a separating device to produce the recess, said punch acting from above on the concave curved side lying down in the guide roller shutter slat. As a cutting unit, a knife is used in this embodiment, the Sloping surface at the outer edge of the lip of the receiving longitudinal edge of the roller shutter slat produces.

Die Riegelstifte sind im Gegensatz zum Stand der Technik spitz zulaufend ausgebildet, wodurch bewirkt wird, dass der Riegelstift sicher und fest in den Metallrand des Rolladenstabes oder der Rolladenlamelle gehalten wird. Außerdem weist der Riegelstift an seiner Außenseite eine Aufrauhung auf.The locking pins are formed tapered in contrast to the prior art, thereby causing the locking pin is held securely and firmly in the metal edge of the roller shutter rod or the shutter blade. In addition, the locking pin has a roughening on its outer side.

Die auswechselbar ausgebildete Werkzeugplatte kann über Rändelschrauben am Träger festgelegt werden, wobei in der Werkzeugplatte Langlochführungen vorgesehen sind und die Rändelschrauben in entsprechende mit Gewinde versehene Bohrungen im Träger eingreifen. Hierdurch sind Korrekturen der Lage, der Stanze und des Messers in einfachster Weise möglich.The replaceable trained tool plate can be set by thumbscrews on the carrier, being provided in the tool plate slot guides and the thumbscrews engage in corresponding threaded holes in the carrier. As a result, corrections of the position, the punch and the knife in the simplest way possible.

Die Werkzeugplatte kann bei einer anderen Ausführungsform auch um eine quer zu ihrer Längsachse verlaufende Schwenkachse geschwenkt werden, um damit Höhenkorrekturen der Werkzeugplatte vorzunehmen.In another embodiment, the tool plate can also be pivoted about a pivot axis extending transversely to its longitudinal axis, in order thereby to make height corrections of the tool plate.

Die von dem Schneidaggregat in der äußeren Randkante der Lippe des Aufnahmelängsrandes der Rolladenlamelle hergestellte Schrägfläche dient dazu, dass die mit der Ausstanzung und dem Riegelstift versehene Rolladenlamelle nunmehr problemlos in die nächstfolgende Rolladenlamelle eingeschoben werden kann.The oblique surface produced by the cutting unit in the outer peripheral edge of the lip of the receiving longitudinal edge of the roller shutter lamella serves to ensure that the roller shutter lamella provided with the punched-out and latch pin can now be easily inserted into the next following roller shutter lamella.

Bei einer anderen Ausführungsform der grundsätzlichen erfindungsgemäßen Überlegung ist anstelle der Stanze ein Sägeblatt vorgesehen, das die Ausnehmung im Aufnahmelängsrand der Rolladentamelle herstellt. Die Schrägfläche am äußeren Rand der Lippe des Aufnahmelängsrandes wird bei dieser Ausführungsform durch eine Schere erzeugt, die auf der Werkzeugplatte um eine vertikale Achse schwenkbar gelagert ist, wobei die Griffschenkel dieser Schere von einem Betätigungsblock betätigt werden, der über eine Pneumatikzylinderanordnung in Richtung der Längsachse der Werkzeugplatte bewegt werden kann und dadurch auf die Griffschenkel einwirkt und die Schneidschenkel der Schere schließt. Da die Schere um eine vertikale Achse schwenkbar gelagert ist, kann sie, sobald der Aufnahmelängsrand in die geöffneten Schneidschenkel eingeführt ist, sich ihren Weg selbst suchen und damit korrekt die Schrägfläche herstellen.In another embodiment of the basic inventive idea, a saw blade is provided instead of the punch, which produces the recess in the receiving longitudinal edge of the roller blind. The inclined surface on the outer edge of the lip of the receiving longitudinal edge is generated in this embodiment by a pair of scissors, which is pivotally mounted on the tool plate about a vertical axis, wherein the Handle legs of this pair of scissors are actuated by an actuating block which can be moved via a pneumatic cylinder assembly in the direction of the longitudinal axis of the tool plate and thereby acts on the gripping arms and closes the cutting legs of the scissors. Since the scissors is mounted pivotably about a vertical axis, it can, as soon as the receiving longitudinal edge is inserted into the open cutting legs, find their own way and thus produce the inclined surface correctly.

Weiterhin trägt im vorliegenden Fall der Träger 22 eine Trenneinrichtung 20, die als Sägeblatt 20a erkennbar ist und umlaufend angetrieben wird, wobei die Antriebseinrichtung nicht dargestellt ist.Furthermore, in the present case, the carrier 22 carries a separating device 20, which is recognizable as a saw blade 20a and is driven in rotation, wherein the drive device is not shown.

Weiterhin trägt der Träger 22 eine Führung 15 für einen Rolladenstab 1, wobei in der Zeichnung gemäß Fig. 3 der Rolladenstab so dargestellt ist, dass er von der Führung 15 und von dem Sägeblatt 20a und der Schere 23 entfernt ist, und es ist erkennbar, dass bereits das Sägeblatt 20a, die Ausnehmung 6 und die Schere 23 die Schrägfläche 8 hergestellt hat.Furthermore, the carrier 22 carries a guide 15 for a roller shutter rod 1, wherein in the drawing of FIG. 3, the roller shutter rod is shown as being away from the guide 15 and from the saw blade 20 a and the scissors 23, and it can be seen that the saw blade 20a, the recess 6 and the scissors 23 have already produced the inclined surface 8.

Durch die Vor- und Zurückbewegung der Kolbenstange 29 werden gesteuert durch die Anschlagbolzen 33 und 34 die Griffschenkel 36 und 35 betätigt, derart, dass bei einer Zurückbewegung der Kolbenstange 29 die Schere 23 geschlossen wird, während bei einer Vorbewegung die Schneidschenkel 42 und 43 geöffnet werden.By the back and forth movement of the piston rod 29 are controlled by the stop pins 33 and 34, the handle legs 36 and 35 are actuated such that upon a return movement of the piston rod 29, the scissors 23 is closed, while at a forward movement, the cutting legs 42 and 43 are opened ,

Der Führungsbolzen 31 führt sich in der Werkzeugplatte 10 in einem in der Zeichnung erkennbaren Langloch 32, das sich von seinem hinteren zu seinem vorderen Ende verjüngt, und zwar keilförmig verjüngt, so dass der eigentliche Betätigungsblock 28 dann, wenn der Führungsbolzen 31 am rückwärtigen Ende des Langloches 32 steht, eine größere Schwenkbewegung ausführen kann als dann, wenn der Führungsbolzen 31 am vorderen Ende des Langloches angelangt ist. Hierdurch ist die Möglichkeit gegeben, dass sich die Schere, d. h. also die Schneidschenkel 42 und 43, in Kontakt mit dem Aufnahmelängsrand der sich in der Führung befindlichen Rolladenlamelle 1 einjustieren kann.The guide pin 31 results in the tool plate 10 in a recognizable in the drawing slot 32, which tapers from its rear to its front end, namely tapered wedge-shaped, so that the actual operating block 28, when the guide pin 31 at the rear end of the Langloches 32 is, can perform a larger pivotal movement than when the guide pin 31 has reached the front end of the slot. This gives the possibility that the scissors, d. H. Thus, the cutting legs 42 and 43, in contact with the receiving longitudinal edge of the located in the guide roller shutter 1 can einjustieren.

Auch bei dieser Ausführungsform arbeitet die Vorrichtung wie folgt:Also in this embodiment, the device operates as follows:

Wird die Rolladenlamelle 1 eingebettet in ihre Führung 15 und mit der konkaven Seite B nach unten gerichtet in die Führung eingeschoben, betätigt sie einen Schalter, der bewirkt, dass sowohl das Sägeblatt 20a in Umdrehung versetzt wird wie auch die Schere 23 geschlossen wird, so dass gleichzeitig sowohl die Ausnehmung 6 wie auch die Schrägfläche 8 hergestellt werden. Gleichzeitig wird auch hier - was aus der Zeichnung nicht zu erkennen ist - über den Nageler 18 ein entsprechender Riegelstift 7 in den Bereich der Verhakungsrippe 3 eingeschossen.If the roller shutter slat 1 inserted embedded in its guide 15 and with the concave side B downwards inserted into the guide, it actuates a switch which causes both the saw blade 20a is rotated as well as the scissors 23 is closed, so that at the same time both the recess 6 and the inclined surface 8 are produced. At the same time - what can not be seen from the drawing here is - shot over the nailer 18 a corresponding locking pin 7 in the region of Verhakungsrippe 3.

Durch die mögliche Schwenkbewegung des Schneidaggregates 21 kann bei geringfügigen Abmessungsunterschieden in den einzelnen Rolladenlameiten doch eine genaue Zentrierung der Schneidschenkel 42 und 43 herbeigeführt werden, und zwar automatisch sucht sich die Schere 23 ihre richtige Stellung und wird dann durch Anlage der Anschlagbolzen 33 und 34 bei der Zurückbewegung der Kolbenstange 29 geschlossen.Due to the possible pivoting movement of the cutting unit 21, a slight centering of the cutting legs 42 and 43 can be brought about with slight dimensional differences in the individual roller shutter loops, and that automatically seeks the scissors 23 their proper position and is then by abutment of the stop pins 33 and 34 in the Return movement of the piston rod 29 closed.
