Gemäß einer günstigen Variante der Erfindung ist die Rahmengreifeinrichtung um wenigstens 90° schwenkbar. Damit ist die Rahmengreifeinrichtung geeignet, eine Rahmenecke mit einem Eckenwinkel von 90° zu einer bestimmten Position hin zu bewegen und aus dieser Position durch Drehung der Rahmenecke um 90° heraus zu bewegen.According to a favorable variant of the invention, the frame gripping device is pivotable by at least 90 °. Thus, the frame gripping device is adapted to move a frame corner with a corner angle of 90 ° to a certain position and to move out of this position by rotation of the frame corner by 90 °.
Es hat sich zudem als vorteilhaft erwiesen, wenn die Rahmengreifeinrichtung auf einer Schiene linear führbar aufgehängt ist. Somit kann sich die Rahmengreifeinrichtung beispielsweise oberhalb der waagerechten Auflage linear zu einer bestimmten Position hin bzw. von dieser weg bewegen.It has also proven to be advantageous if the frame gripping device is suspended linearly executable on a rail. Thus, the frame gripping device, for example, above the horizontal support linearly to a certain position or move away from it.
Gemäß einem günstigen Beispiel der Erfindung sind die Spannelemente als Spannplatten ausgebildet, die senkrecht von außen auf die Schenkel der Rahmenecke zu und senkrecht nach außen von den Schenkeln der Rahmenecke weg bewegbar sind. Durch diese Form der Ausführung kann ein Fensterrahmen oder Fensterrahmenelement an der Rahmenecke besonders stabil gehalten werden.According to a favorable example of the invention, the clamping elements are designed as clamping plates which are movable vertically from the outside to the legs of the frame corner and perpendicular to the outside of the legs of the frame corner away. By this form of execution, a window frame or window frame element can be kept particularly stable at the frame corner.
Entsprechend einer bevorzugten Ausführungsvariante sind an den Spannplatten Spannbacken aus nicht rostendem Stahl und/oder Kunststoff vorgesehen. Durch die Spannbacken können die Schenkel der Rahmenecke zuverlässig gehalten werden, wobei die Haltekraft nur im Bereich der Spannbacken auf den Fensterrahmen oder das Fensterrahmenelement ausgeübt werden muss. Durch das Material der Spannbacken kann zudem ein langzeitstabiler Greifmechanismus erhalten werden.According to a preferred embodiment, clamping jaws made of stainless steel and / or plastic are provided on the clamping plates. By the clamping jaws, the legs of the frame corner can be reliably held, the holding force must be exercised only in the region of the clamping jaws on the window frame or the window frame element. By the material of the jaws also a long-term stable gripping mechanism can be obtained.
Gemäß einem weiteren vorteilhaften Beispiel der Erfindung weist das Zentrierelement zwei, innen an den Schenkeln der Rahmenecke platzierbare Seitenflächen auf, wobei der Winkel zwischen den Seitenflächen dem Winkel zwischen den Schenkeln der Rahmenecke entspricht. Hiermit können die Seitenflächen des Zentrierelementes parallel zu den Innenseiten der Schenkel der Rahmenecke an den Schenkeln innen angreifen, während die Schenkel von außen durch die Spannplatten erfasst werden können. Entsprechend kann die Rahmenecke besonders stabil gehalten und bewegt werden.According to a further advantageous example of the invention, the centering element has two, on the inside of the legs of the frame corner placeable side surfaces, wherein the angle between the side surfaces corresponds to the angle between the legs of the frame corner. Hereby, the side surfaces of the centering element parallel to the inner sides of the legs of the frame corner on the legs attack the inside, while the legs can be detected from the outside by the clamping plates. Accordingly, the frame corner can be kept very stable and moved.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung weist der zwischen den an der Rahmenecke platzierbaren Seitenflächen des Zentrierelementes ausgebildete Winkel einen abgeflachten Spitzenbereich auf. Hiermit kann ein eventuell negativer Einfluss eines Spitzenbereiches des Zentrierelementes auf den Innenbereich der Rahmenecke vermieden werden. Auch kann durch diese spezielle Ausbildung das Zentrierelement einfach aus dem Inneren der Rahmenecke fortbewegt werden bzw. in der Rahmenecke platziert werden.According to a further preferred embodiment of the invention, the angle formed between the side surfaces of the centering element which can be placed on the frame corner has a flattened tip region. This can be a negative if necessary Influence of a tip region of the centering on the interior of the frame corner can be avoided. Also, the centering element can be easily moved from the interior of the frame corner or placed in the frame corner by this special training.
In einem speziellen Ausführungsbeispiel der Erfindung weist das Zentrierelement eine Grundstellung und in Abhängigkeit vom Profil und/oder der Positionierung des Fensterrahmens oder Fensterrahmenelementes verschiedene Arbeitspositionen in der Rahmenecke auf. Somit kann die Position des Zentrierelementes an verschiedene Positionen des Fensterrahmens oder Fensterrahmenelementes und/oder verschiedene Bearbeitungsvorgänge an der Rahmenecke angepasst werden. In der Grundstellung kann das Zentrierelement während einer Bearbeitung des Fensterrahmens oder Fensterrahmenelementes positioniert werden, ohne den Bearbeitungsvorgang zu stören.In a special embodiment of the invention, the centering element has a basic position and, depending on the profile and / or the positioning of the window frame or window frame element, different working positions in the frame corner. Thus, the position of the centering element can be adapted to different positions of the window frame or window frame element and / or various processing operations on the frame corner. In the basic position, the centering element can be positioned during processing of the window frame or window frame element, without disturbing the machining process.
Günstiger Weise entspricht der Drehpunkt der Rahmengreifeinrichtung einer Arbeitsposition des Zentrierelementes. Somit kann die Rahmenecke des Fensterrahmens oder Fensterrahmenelementes um das Zentrierelement gedreht werden, womit eine definierte und einfach berechenbare Drehbewegung des Fensterrahmens oder Fensterrahmenelementes realisiert werden kann.Conveniently, the pivot point of the frame gripper corresponds to a working position of the centering element. Thus, the frame corner of the window frame or window frame element can be rotated about the centering element, whereby a defined and easily calculable rotational movement of the window frame or window frame element can be realized.
Gemäß einer speziellen Ausführungsvariante der Erfindung ist die Auflage Bestandteil einer Fensterrahmentransporteinrichtung, an welcher wenigstens eine Bearbeitungsvorrichtung für den Fensterrahmen oder das Fensterrahmenelement vorgesehen ist. Auf diese Weise kann der Fensterrahmen oder das Fensterrahmenelement direkt auf der Auflage zu der Bearbeitungsvorrichtuhg hin bzw. von dieser weg transportiert werden. Dabei kann die Bearbeitungsvorrichtung so positioniert werden, dass ein direktes Einlegen des Fensterrahmens oder Fensterrahmenelementes mit Hilfe der Fensterrahmentransporteinrichtung in die Bearbeitungsvorrichtung möglich ist, so dass kein weiterer Zwischenschritt für ein Positionieren des Fensterrahmens oder des Fensterrahmenelementes in der Bearbeitungsvorrichtung erforderlich ist.According to a special embodiment of the invention, the support is part of a window frame transport device, on which at least one processing device for the window frame or the window frame element is provided. In this way, the window frame or the window frame element can be transported directly on the support to the Bearbeitungsvorrichtuhg or away. In this case, the processing device can be positioned so that a direct insertion the window frame or window frame element is possible by means of the window frame transport device into the processing device, so that no further intermediate step is required for positioning the window frame or the window frame element in the processing device.
Entsprechend einer vorteilhaften Weiterbildung der Erfindung ist die Bearbeitungsvorrichtung in einem Winkel von 45° zu einer Bewegungsrichtung des Fensterrahmens oder Fensterrahmenelements auf der Auflage angeordnet. Somit kann ein Bearbeitungswerkzeug der Bearbeitungsvorrichtung direkt an der Rahmenecke des Fensterrahmens oder Fensterrahmenelements angreifen, um beispielsweise die jeweilige Ecke zu verputzen. Dies ist insbesondere dann von Vorteil, wenn es sich bei der zu verputzenden Rahmenecke um eine Ecke mit einem Winkel von 90° handelt, bei welcher der Fensterrahmen direkt in die Bearbeitungsvorrichtung bzw. den Eckenputzer eintransportiert werden kann.According to an advantageous embodiment of the invention, the processing device is arranged at an angle of 45 ° to a direction of movement of the window frame or window frame element on the support. Thus, a processing tool of the processing device can act directly on the frame corner of the window frame or window frame element, for example, to plaster the respective corner. This is particularly advantageous when it comes to the frame corner to be plastered around a corner with an angle of 90 °, in which the window frame can be transported directly into the processing device or the corner cleaner.
Die erfindungsgemäße Vorrichtung kann auch ohne einen Bezug zu einer Bearbeitungsvorrichtung dazu genutzt werden, einen Fensterrahmen oder ein Fensterrahmenelement zu bewegen oder zu drehen.The device according to the invention can also be used without a reference to a processing device to move or rotate a window frame or a window frame element.
Erfindungsgemäß wird das Zentrierelement zum Klemmen der Rahmenecke in einem Winkel von etwa 45° zu den Schenkeln der Rahmenecke linear von innen auf die Rahmenecke zu bewegt und zum Freigeben der Rahmenecke nach innen von der Rahmenecke weg bewegt. Hiermit kann ein freier Raum innerhalb der Rahmenecke günstig genutzt werden, um das Zentrierelement zwischen den Schenkeln zu positionieren bzw. zwischen den Schenkeln der Rahmenecke zu führen. Durch den Winkel von etwa 45° zu den Schenkeln der Rahmenecke kann das Zentrierelement etwa zur gleichen Zeit an den Schenkeln der Rahmenecke angreifen, wodurch eine gleichmäßige Kraftbelastung auf die Schenkel der Rahmenecke erfolgt und umgekehrt die Schenkel der Rahmenecke bei einem Fortbewegen des Zentrierelementes gleichmäßig entlastet werden.According to the invention, the centering element for clamping the frame corner is moved at an angle of about 45 ° to the legs of the frame corner linearly from the inside to the frame corner and moves to release the frame corner inwardly away from the frame corner. Hereby, a free space within the frame corner can be used favorably to position the centering between the legs or to lead between the legs of the frame corner. Due to the angle of about 45 ° to the legs of the frame corner, the centering can attack about the same time on the legs of the frame corner, whereby a uniform force on the legs of the frame corner takes place and vice versa, the legs of the frame corner are evenly relieved in a movement of the centering ,
Mit Hilfe des erfindungsgemäßen Verfahrens kann die Rahmenecke eines Fensterrahmens oder Fensterrahmenelementes so eingespannt werden, dass sie mit Hilfe der Rahmengreifeinrichtung sowohl linear mitgeführt als auch gedreht werden kann. Dabei bewegt sich nicht nur die eingespannte Rahmenecke selbst, sondern der gesamte Fensterrahmen bzw. das gesamte Fensterrahmenelement, so dass andere Rahmenecken des Fensterrahmens oder Fensterrahmenelementes ebenfalls ihre Position entsprechend der linearen und der Drehbewegung der von der Rahmengreifeinrichtung gespannten Rahmenecke verändern.With the aid of the method according to the invention, the frame corner of a window frame or window frame element can be clamped in such a way that it can be both linearly guided and rotated with the aid of the frame gripping device. In this case, not only the clamped frame corner moves itself, but the entire window frame or the entire window frame element, so that other frame corners of the window frame or window frame element also change their position according to the linear and rotational movement of the stretched frame frame gripping frame corner.
Auf diese Weise kann einfach und schnell ein Fensterrahmen oder Fensterrahmenelement befördert und in seiner Ausrichtung verändert werden, so dass beispielsweise die Rahmenecke des Fensterrahmens oder Fensterrahmenelementes einer Bearbeitungsvorrichtung zugeführt werden kann, dort bearbeitet werden kann und die Rahmenecke bei ihrem Herausbewegen aus der Bearbeitungsposition nach erfolgter Bearbeitung durch eine andere Rahmenecke effizient ersetzt werden kann. Das erfindungsgemäße Verfahren besitzt den Vorteil, dass die Schritte des Transportierens und Wegtransportierens sowie des Drehens des Fensterrahmens oder Fensterrahmenelementes direkt an der Bearbeitungsvorrichtung durch eine einzige Rahmengreifeinrichtung realisiert werden können. Entsprechend kann eine Bearbeitung des Fensterrahmens oder Fensterrahmenelementes bei geringem Platzbedarf für die Transport- und Bearbeitungsvorrichtung realisiert werden.In this way, a window frame or window frame element can be easily and quickly conveyed and changed in its orientation, so that for example the frame corner of the window frame or window frame element can be fed to a processing device, can be edited there and the frame corner in its move out of the processing position after processing can be efficiently replaced by another frame corner. The inventive method has the advantage that the steps of transporting and Wegtransportierens and the rotation of the window frame or window frame element directly to the processing device can be realized by a single frame gripping device. Accordingly, a processing of the window frame or window frame element can be realized with a small footprint for the transport and processing device.
Gemäß einer vorteilhaften Ausführungsform der Erfindung bewegt sich die Rahmengreifeinrichtung zum Klemmen der Rahmenecke nach unten und zum Freigeben der Rahmenecke nach oben. Somit kann die Rahmengreifeinrichtung zum Bewegen der Rahmenecke einfach und schnell auf die Rahmenecke zu bewegt werden und beispielsweise für eine Bearbeitung der Rahmenecke von der Rahmenecke weg bewegt werden.According to an advantageous embodiment of the invention, the frame gripping device moves to clamp the frame corner down and to release the frame corner upwards. Thus, the frame gripping device for moving the frame corner can be easily and quickly moved to the frame corner and moved, for example, for a processing of the frame corner of the frame corner away.
Nach einem weiteren Beispiel der Erfindung sind die Spannelemente Spannplatten, die sich zum Klemmen der Rahmenecke senkrecht von außen auf die Schenkel der Rahmenecke zu bewegen und zum Freigeben der Rahmenecke senkrecht nach außen von den Schenkeln der Rahmenecke weg bewegen. Durch die senkrechte Bewegung der Spannplatten relativ zu den Schenkeln der Rahmenecke könner die Schenkel der Rahmenecke besonders stabil geklemmt werden.According to a further example of the invention, the clamping elements clamping plates, which move to clamp the frame corner perpendicular from the outside to the legs of the frame corner and move to release the frame corner perpendicular to the outside of the legs of the frame corner. By the vertical movement of the clamping plates relative to the legs of the frame corner könner the legs of the frame corner are clamped particularly stable.
In einem bevorzugten Beispiel der Erfindung schwenkt die Rahmengreifeinrichtung um eine Arbeitsposition des Zentrierelementes. Damit kann die Arbeitsposition des Zentrierelementes als Drehpunkt für die Rahmengreifeinrichtung dienen, wobei der Drehpunkt vorteilhafter Weise zur Berechnung der Drehbewegung der Rahmengreifeinrichtung und damit des Fensterrahmens oder Fensterrahmenelementes eingesetzt werden kann.In a preferred example of the invention, the frame gripping device pivots about a working position of the centering element. Thus, the working position of the centering serve as a fulcrum for the frame gripping device, the fulcrum can be used advantageously for calculating the rotational movement of the frame gripping device and thus the window frame or window frame element.
Es ist zudem günstig, wenn die Rahmenecke von der Rahmengreifeinrichtung zu einer Bearbeitungsvorrichtung transportiert wird, direkt in die Bearbeitungsvorrichtung ohne weiteren Zwischenschritt eingelegt wird, an der Bearbeitungsvorrichtung freigegeben wird und dort bearbeitet wird. So können durch die Rahmengreifeinrichtung Fensterrahmen oder Fensterrahmenelemente an der Rahmenecke geklemmt und so zu der Bearbeitungsvorrichtung transportiert und dort eingelegt werden, dass ein Bearbeitungsvorgang an der Bearbeitungsvorrichtung sofort erfolgen kann. Es ist zudem von Vorteil, wenn die Rahmengreifeinrichtung die Rahmenecke nach der Bearbeitung durch die Bearbeitungsvorrichtung greift und so von der Bearbeitungsvorrichtung weg bewegt, dass eine Rahmenecke des Fensterrahmens oder des Fensterrahmenelementes gleichzeitig mit dem Wegbewegen der bearbeiteten Rahmenecke zu der Bearbeitungsvorrichtung hin bewegt wird. Entsprechend kann mit Hilfe des erfindungsgemäßen Verfahrens eine bereits durch die Bearbeitungsvorrichtung bearbeitete Rahmenecke des Fensterrahmens oder Fensterrahmenelementes durch eine noch nicht bearbeitete Rahmenecke des Fensterrahmens oder Fensterrahmenelementes ersetzt werden, ohne dass der Fensterrahmen oder das Fensterrahmenelement aus der Bearbeitungsvorrichtung herausgezogen werden muss. Allein durch das Bewegen des Fensterrahmens oder Fensterrahmenelementes mittels der Rahmengreifeinrichtung der vorliegenden Erfindung kann sich die weitere zu bearbeitende Rahmenecke des Fensterrahmens oder Fensterrahmenelementes so vorteilhaft in eine Bearbeitungsposition an der Bearbeitungsvorrichtung hinein bewegen, dass weitere Zwischenschritte zum Einlegen oder Positionieren des Fensterrahmens oder Fensterrahmenelementes an der Bearbeitungsvorrichtung wegfallen können.It is also advantageous if the frame corner is transported by the frame gripper to a processing device, is inserted directly into the processing device without further intermediate step, is released on the processing device and processed there. Thus, by the frame gripper window frame or window frame elements clamped to the frame corner and transported to the processing device and inserted there that a machining operation on the processing device can be done immediately. It is also advantageous if the frame gripping device grips the frame corner after processing by the processing device and moves away from the processing device such that a frame corner of the window frame or window frame element is moved towards the processing device at the same time as the processed frame corner is moved away. Accordingly, with the aid of the method according to the invention, a frame corner of the window frame or window frame element which has already been processed by the machining device can be replaced by a not yet processed frame corner of the window frame or window frame element without the window frame or the window frame element having to be pulled out of the machining device. Alone by moving the window frame or window frame member by means of the frame gripping device of the present invention, the further to be processed frame corner of the window frame or window frame element can move so advantageous in a processing position on the processing device that further intermediate steps for inserting or positioning the window frame or window frame element on the processing device can fall away.

Es hat sich als günstig erwiesen, die Drehbewegung der Rahmengreifeinrichtung 4 der Linearbewegung der Rahmengreifeinrichtung 4 so zu überlagern, dass eine in einer Arbeitsposition befindliche Rahmenecke 21 des Fensterrahmens 2 schneller aus dieser Arbeitsposition weg bewegt wird, als sich eine andere, nächste Rahmenecke 22 in die Arbeitsposition hin bewegt. Im weiteren Verlauf ist die Geschwindigkeit der aus der Arbeitsposition weg bewegten Rahmenecke 21 zu verlangsamen, während die Geschwindigkeit der sich auf die Arbeitsposition zu bewegenden Rahmenecke 22 größer wird.
