Die erfindungsgemäße Vorrichtung dient zum Herausschneiden einer mittels einer Kleberaupe in einer Umrahmung fixierten Scheibe und umfasst eine Werkzeugeinheit mit einen Vakuumsaugteller, eine maschinell betätigbare Winde, auf welcher eine Trennschnur auf- und abrollbar gelagert ist und eine Umlenkrolle zur Führung der Trennschnur. Die Werkzeugeinheit ist mit dem Vakuumsaugteller auf einer Oberfläche der Scheibe fixiert. Weiterhin umfasst die erfindungsgemäße Vorrichtung einen Anker-Sauger, welcher auf einer Oberfläche der Scheibe fixiert ist, wobei die Trennschnur wenigstens an einer Einstichstelle durch die Kleberaupe geführt ist. Das freie Ende der Trennschnur wird an dem Anker-Sauger befestigt, wobei durch ein maschinelles Betätigen der Winde die Trennschnur an dieser aufgewickelt wird und dadurch die Kleberaupe durchtrennt.The device according to the invention serves for cutting out a disk fixed in a frame by means of a glue bead and comprises a tool unit with a vacuum suction plate, a mechanically operable winch on which a separating line is mounted and unrolled and a deflection roller for guiding the separating line. The tool unit is fixed with the vacuum suction plate on a surface of the disc. Furthermore, the device according to the invention comprises an anchor-suction, which is fixed on a surface of the disc, wherein the separating cord is guided at least at a puncture site by the adhesive bead. The free end of the separating cord is fastened to the anchor vacuum cleaner, wherein the separating cord is wound up by means of a mechanical actuation of the winch and thereby cuts through the adhesive bead.
Weiter betrifft die Erfindung ein entsprechendes Verfahren.Furthermore, the invention relates to a corresponding method.
Besonders vorteilhaft ist die Umrahmung Bestandteil eines Kraftfahrzeugs, wobei die Scheibe eine Frontscheibe, Heckscheibe, Seitenscheibe oder Panoramascheibe im Dachbereich eines Kraftfahrzeugs ist.Particularly advantageously, the frame is part of a motor vehicle, wherein the disc is a windscreen, rear window, side window or panoramic window in the roof area of a motor vehicle.
Ein wesentlicher Vorteil der Erfindung besteht darin, dass zum Durchtrennen der Kleberaupe eine Trennschnur verwendet wird. Aufgrund der mittlerweile technisch realisierbaren Eigenschaften wird mit der Trennschnur ebenso wie mit einem Schneiddraht ein sicheres Durchtrennen der Kleberaupe ermöglicht. Im Vergleich zu Schneiddrähten bietet die Verwendung einer Trennschnur als zusätzliche Vorteile, dass Beschädigungen der Umrahmung oder generell des Innenraums eines Kraftfahrzeugs ausgeschlossen werden. Zudem besteht keine Verletzungsfahr für das Bedienpersonal.An essential advantage of the invention is that a severing cord is used to sever the adhesive bead. Because of the meantime technically realizable properties with the separating cord as well as with a cutting wire a secure cutting of the adhesive bead allows. Compared to cutting wires, the use of a separating cord offers the additional advantages of excluding damage to the frame or, in general, the interior of a motor vehicle. In addition, there is no risk of injury to the operating personnel.
Die erfindungsgemäß eingesetzte Trennschnur weist bei einem geringen Querschnitt eine hohe Stabilität und Festigkeit, insbesondere Reißfestigkeit auf, wodurch diese als Schneidmittel geeignet ist. Unter dem Begriff Schnur wird im Sinne der Erfindung jegliche strangartige, insbesondere faserstrangartige Struktur verstanden. Die Trennschnur besteht dabei bevorzugt aus einem reißfesten Kunststoff-Material, wie beispielsweise Polyethylen. Geeignete handelsübliche Materialien sind Spectra, Dyneema, Nylon.The separating cord used according to the invention has a high stability and strength, in particular tensile strength, with a small cross-section, as a result of which it is suitable as a cutting agent. For the purposes of the invention, the term cord means any strand-like, in particular fiber-strand-like structure. The separating cord preferably consists of a tear-resistant plastic material, such as polyethylene. Suitable commercial materials are Spectra, Dyneema, Nylon.
Ein weiterer Vorteil der erfindungsgemäßen Vorrichtung besteht in deren einfachen Bedienbarkeit, wobei besonders vorteilhaft ist, dass diese von nur einer Person betätigt werden kann.Another advantage of the device according to the invention is its ease of use, it being particularly advantageous that it can be operated by only one person.
Hierzu muss die Bedienperson lediglich die Werkzeugeinheit und den Anker-Sauger in geeigneten Positionen auf eine Oberfläche der Scheibe aufsetzen. Je nachdem, ob die Werkzeugeinheit und der Anker-Sauger auf verschiedenen Oberflächen oder derselben Oberfläche der Scheibe befestigt werden, wird die Trennschnur an einer oder zwei Einstichstellen durch die Kleberaupe geführt. Die Einstichstellen können einfach und schnell mit mechanischen Durchstechwerkzeugen erzeugt werden.To do this, the operator merely has to place the tool unit and the anchor vacuum cleaner in suitable positions on a surface of the disk. Depending on whether the tool unit and the anchor-sucker are mounted on different surfaces or the same surface of the disc, the separating cord is passed through the adhesive bead at one or two puncture sites. The puncture sites can be created easily and quickly with mechanical piercing tools.
Zum Durchtrennen der Kleberaupe muss dann lediglich die Trennschnur auf der Winde aufgewickelt werden. Dies erfolgt erfindungsgemäß maschinell derart, dass die Aufwicklung mit der erforderlichen Drehzahl erfolgt, so dass ein sicherer, einwandfreier Schneidvorgang mit der Trennschnur erzielt wird. Diese Drehzahl liegt vorteilhaft im Bereich von 0-500 U/min.To cut the adhesive bead then only the separating cord must be wound on the winch. This is done according to the invention mechanically such that the winding takes place at the required speed, so that a safer, flawless cutting process is achieved with the separating cord. This speed is advantageously in the range of 0-500 U / min.
Besonders vorteilhaft ist an der Winde ein Anschlussmittel fĂĽr einen mit einem Akkumulator betriebenen Bohrer oder Schrauber vorgesehen.Particularly advantageously, a connection means for a driller or screwdriver operated with an accumulator is provided on the winch.
Mit derartigen sogenannten Akku-Bohrern oder Akku-Schraubern lässt sich der gewünschte Drehzahlbereich für ein Auf- und Abwickeln der Trennschnur realisieren.With such so-called cordless drills or cordless screwdrivers, the desired speed range can be realized for winding and unwinding the separating cord.
Gemäß einer vorteilhaften Ausgestaltung der Erfindung weist die Werkzeugeinheit ein auf dem Vakuumsaugteller angeordnetes Oberteil auf, welches ein über den Vakuumsaugteller hervorstehendes, dicht oberhalb der Unterkante des Vakuumsaugtellers verlaufendes Kopfteil aufweist, an dessen Vorderende die Umlenkrolle drehbar gelagert ist. Das Kopfteil weist zwei in spitzem Winkel auf das Vorderende zulaufende Seitenkanten auf, wobei eine der Seitenkanten eine Ausrichtkante zur Ausrichtung der Werkzeugeinheit auf der Oberfläche der Scheibe ausbildet.According to an advantageous embodiment of the invention, the tool unit has an upper part arranged on the vacuum suction plate, which has a head part protruding above the vacuum suction plate and running close to the lower edge of the vacuum suction plate, at the front end of which the guide roller is rotatably mounted. The head portion has two side edges tapering toward the front end at an acute angle, with one of the side edges forming an alignment edge for aligning the tool unit with the surface of the disk.
Das Oberteil besteht dabei bevorzugt aus einem Kunststoff-Spritzgussteil, welches kostengĂĽnstig herstellbar ist.The upper part is preferably made of a plastic injection-molded part, which is inexpensive to produce.
Durch die Anbringung der Umlenkrolle an dem Vorderende des Kopfteils wird eine Führung der Trennschnur derart erreicht, dass mit dieser ein einwandfreier, optimierter Schneidvorgang durchgeführt werden kann. Wesentlich hierbei ist zum einen, dass das Kopfteil dicht oberhalb der Unterkante des Vakuumsaugtellers positioniert ist. Damit wird unabhängig von der Scheibengeometrie bei Aufsetzen der Werkzeugeinheit mit dem Vakuumsaugteller auf der Scheibe ein flacher Anstellwinkel der Trennschnur zur Scheibe erreicht, was eine wesentliche Voraussetzung für einen einwandfreien Schneidvorgang ist. Weiterhin ist wesentlich, dass die Schneidkanten des Kopfteils in einem spitzen Winkel auf das Vorderende des Kopfteils zulaufen. Die Umlenkung der Trennschnur aus der Umlenkrolle im Bereich des Vorderendes des Kopfteils kann damit so erfolgen, dass beliebige Winkelstellungen der zum Anker-Sauger geführten Trennschnur erhalten werden, so dass eine geeignete Ausrichtung der Werkzeugeinheit zum Anker-Sauger zur Erzielung eines optimalen Schneidvorgangs ermöglicht wird.By attaching the deflection roller at the front end of the head part a guide of the separating cord is achieved such that with this a perfect, optimized cutting process can be performed. It is essential on the one hand that the head part is positioned just above the lower edge of the vacuum suction plate. Thus, regardless of the disc geometry when placing the tool unit with the vacuum suction on the disc a flat angle of the separating cord to the disc is achieved, which is an essential prerequisite for a perfect cutting process. Furthermore, it is essential that the cutting edges of the head part taper at an acute angle to the front end of the head part. The deflection of the separating cord from the deflection roller in the region of the front end of the head part can thus be made so that any angular positions of the guided to the anchor-suction separator cord are obtained, so that a suitable orientation of the Tool unit to the anchor-suction to achieve an optimal cutting process is made possible.
Besonders vorteilhaft ist weiterhin, dass eine Seitenkante des Kopfteils eine Ausrichtkante bildet. Diese Ausrichtkante dient als Ausrichthilfe, mittels derer die Werkzeugeinheit auf einfache Weise in einer bestimmten Sollposition auf der Scheibe platziert und fixiert werden kann.It is furthermore particularly advantageous that a side edge of the head part forms an alignment edge. This alignment edge serves as an alignment aid, by means of which the tool unit can be easily placed and fixed in a specific target position on the disk.
Gemäß einer zweckmäßigen Ausgestaltung der Erfindung ist an dem Kopfteil ein Führungsstift zur Führung der Trennschnur vorgesehen.According to an expedient embodiment of the invention, a guide pin for guiding the separating cord is provided on the head part.
Dadurch wird ein unerwünschtes Führen der Trennschnur an Elementen des Oberteils, was zu unerwünschten Reibungskräften oder sogar einem Verkanten der Trennschnur führen kann, vermieden.As a result, an undesirable guiding of the separating cord to elements of the upper part, which can lead to undesired frictional forces or even tilting of the separating cord, is avoided.
Weiterhin ist vorteilhaft, dass die Winde eine Welle aufweist, die in zwei in Abstand zueinander angeordneten Armen des Oberteils der Werkzeugeinheit gelagert ist. In Aufnahmen der Arme sind Lagerbuchsen zur Lagerung der Winde vorgesehen.Furthermore, it is advantageous that the winch has a shaft which is mounted in two mutually spaced arms of the upper part of the tool unit. In recordings of the arms bearing bushes are provided for mounting the winch.
Die Lagerung der Winde ist somit platz- und kostensparend integriert. Zudem wird ein unerwünschtes Einklemmen der Trennschnur an den Längsenden der Winde vermieden.The storage of the winch is thus integrated space and cost saving. In addition, an undesired clamping of the separating cord at the longitudinal ends of the winch is avoided.
Besonders vorteilhaft ist Welle gegen die Federkraft in einer Federscheibe an einem Arm des Oberteils gelagert.Particularly advantageous shaft is mounted against the spring force in a spring washer on an arm of the upper part.
Dadurch wird eine gewisse Reibungskraft, die auf die Winde wirkt, generiert, wodurch ein unkontrolliertes Auf- oder Abrollen der Trennschnur auf der Winde vermieden wird.As a result, a certain frictional force acting on the winch is generated, whereby an uncontrolled winding or unwinding of the separating cord on the winch is avoided.
Das erfindungsgemäße Verfahren wird vorteilhaft derart durchgeführt, dass zum Durchtrennen der gesamten Kleberaupe die Werkzeugeinheit und/oder der Anker-Sauger nacheinander in unterschiedlichen Positionen an der Scheibe befestigt werden. Für die einzelnen Positionen ist jeweils die Trennschnur wenigstens an einer Einstichstelle durch die Kleberaupe geführt und das freie Ende der Trennschnur an dem Anker-Sauger befestigt. Durch ein maschinelles Betätigen der Winde und ein dadurch bedingtes Aufwickeln der Trennschnur wird an der Winde ein durch die Positionen der Werkzeugeinheit und des Anker-Saugers vorgegebener Abschnitt der Klebraupe durchtrennt.The method according to the invention is advantageously carried out in such a way that the tool unit and / or the tool unit are cut to sever the entire adhesive bead Anchor sucker can be attached in succession in different positions on the disc. For the individual positions, in each case the separating cord is guided through the adhesive bead at least at one puncture site and the free end of the separating cord is fastened to the anchor vacuum cleaner. By a mechanical actuation of the winch and a conditional winding of the separating cord, a predetermined by the positions of the tool unit and the anchor-sucker portion of the adhesive bead is severed on the winch.
Besonders vorteilhaft wird das erfindungsgemäße Verfahren zum Heraustrennen von Scheiben in Kraftfahrzeugen eingesetzt.Particularly advantageous method of the invention is used for separating discs in motor vehicles.
Insbesondere beim Heraustrennen einer Windschutzscheibe eines Kraftfahrzeugs wird bei unveränderter Position des Anker-Saugers die Werkzeugeinheit nacheinander in den Eckbereichen der Windschutzscheibe fixiert, wobei die Ausrichtung der Werkzeugeinheit mittels der Ausrichtkante der Werkzeugeinheit kontrolliert wird.In particular, when separating a windshield of a motor vehicle, the tool unit is fixed one after the other in the corner regions of the windshield with unchanged position of the anchor-sucker, the alignment of the tool unit is controlled by means of the alignment edge of the tool unit.
Bei einem Einsatz des erfindungsgemäßen Verfahrens im Kraftfahrzeug-Bereich hat es sich als vorteilhaft erwiesen, dass die Werkzeugeinheit auf die Oberfläche an der Innenseite des Kraftfahrzeugs aufgesetzt wird. Der Anker-Sauger wird auf der Oberfläche an der Außenseite des Kraftfahrzeugs aufgesetzt. Die Trennschnur wird an nur einer Einstichstelle durch die Kleberaupe geführt.When using the method according to the invention in the motor vehicle sector, it has proved to be advantageous for the tool unit to be placed on the surface on the inside of the motor vehicle. The anchor sucker is placed on the surface on the outside of the motor vehicle. The separating cord is guided through the adhesive bead at only one puncture point.
Diese Anordnung ist besonders vorteilhaft fĂĽr ein Heraustrennen einer Windschutzscheibe eines Kraftfahrzeugs.This arrangement is particularly advantageous for a separation of a windshield of a motor vehicle.
Prinzipiell ist auch eine umgekehrte Anordnung, das heißt die Befestigung der Werkzeugeinheit an der Außenseite und des Anker-Saugers an der Innenseite der Scheibe möglich.In principle, a reverse arrangement, that is, the attachment of the tool unit on the outside and the anchor-suction on the inside of the disc possible.
Generell sind auch Anwendungen denkbar, bei denen sowohl die Werkzeugeinheit als auch der Anker-Sauger an der Innen- oder AuĂźenseite der Scheibe angebracht werden. Dann muss die Trennschnur zweimal durch die Kleberaupe gefĂĽhrt werden.In general, applications are conceivable in which both the tool unit and the anchor-suction on the inside or outside of the disc be attached. Then the dividing line must be passed twice through the adhesive bead.
Das erfindungsgemäße Verfahren kann vorteilhaft dahingehend modifiziert beziehungsweise erweitert sein, dass mit diesem anstelle einer Scheibe ein anderes Teil, insbesondere eine Leiste, ein Emblem oder ein Spoiler eines Kraftfahrzeugs, herausgelöst wird.The method according to the invention can advantageously be modified or extended in such a way that with this instead of a pane another part, in particular a strip, an emblem or a spoiler of a motor vehicle, is detached.

Die Werkzeugeinheit 1 umfasst einen Vakuumsaugteller 2 und ein auf dessen Oberseite aufgebrachtes Oberteil 3, welches in Form eines Kunststoff-SpritzguĂźteils ausgebildet ist. Das Oberteil 3 ist, wie
Der zentrale Bereich des Oberteils 3 bildet einen Griff aus, an dem eine Bedienperson die Werkzeugeinheit 1 aufnehmen kann. An einem Rand des Oberteils 3 sind zwei in Abstand zueinander parallel verlaufende und identisch ausgebildete Arme 8 vorgesehen. Zwischen diesen Armen 8 ist eine Winde 9 gelagert, deren Einzelteile in
Auf der Winde 9 ist eine Trennschnur 16 gelagert, die aus einem reiĂźfesten Kunststoff-Material besteht. Ein freies Ende ist in einem Loch 10a im Zentrum der Welle 10 gelagert.On the
Das Oberteil 3 der Werkzeugeinheit 1 weist weiterhin ein Kopfteil 17 auf, das mit seinem Vorderende, an welchem eine Umlenkrolle 18 drehbar gelagert ist, ĂĽber den Vakuumsaugteller 2 hervorsteht. Die Umlenkrolle 18 dient zur Umlenkung und FĂĽhrung der Trennschnur 16.The
Wie insbesondere aus
Das Kopfteil 17 weist zwei in spitzem Winkel auf dessen Vorderende zulaufende Seitenkanten auf. Eine Seitenkante bildet eine Ausrichtkante 19, die als Ausrichthilfe zur Ausrichtung der Werkzeugeinheit 1 in einer Sollposition auf der Scheibe dient. An der anderen Seitenkante befindet sich eine Schnurklemme 20, in welcher das nicht an der Winde 9 befestigte freie Ende der Trennschnur 16 eingeklemmt werden kann.The
Die Trennschnur 16 kann an der Umlenkrolle 18 so eingefädelt werden, dass die Trennschnur 16 bei Abrollen von der Winde 9 im oder entgegen dem Uhrzeigersinn geführt ist.

Als weiterer Bestandteil der erfindungsgemäßen Vorrichtung wird auf der Außenseite der Windschutzscheibe 22 ein Anker-Sauger 25 befestigt. Dieser Anker-Sauger 25 weist einen umklappbaren Hebel 26 auf, wobei durch Umklappen des Hebels 26 in bekannter Weise ein Unterdruck generiert wird, mittels dessen der Anker-Sauger 25 an der Windschutzscheibe 22 befestigt wird. Weiterhin weist der Anker-Sauger 25 eine Befestigungsvorrichtung 27 auf, an welcher das freie Ende der Trennschnur 16 befestigt, insbesondere festgeklemmt werden kann.As a further part of the device according to the invention an anchor-
Nach Befestigen der Werkzeugeinheit 1 an der Innenseite der Windschutzscheibe 22 und des Anker-Saugers 25 an der Außenseite der Windschutzscheibe 22 wird mit einem Durchstehwerkzeug 28 von einer Bedienperson eine Einstichstelle 29 in der Kleberaupe 24 erzeugt, die sich im Bereich der unteren rechten Ecke der Windschutzscheibe 22 befindet. Dann wird das freie Ende von der Bedienperson durch diese Einstichstelle 29 gefädelt und dann an der Befestigungsvorrichtung 27 des Anker-Saugers 25 befestigt. Diese Situation ist in
Danach erfolgt ein Schneidvorgang, das heißt ein Durchtrennen der Kleberaupe 24 im unteren Bereich der Windschutzscheibe 22 durch ein maschinelles Betätigen der Winde 9 und ein dadurch bedingtes Aufrollen der Trennschnur 16 auf der Winde 9. Hierzu wird, wie besonders deutlich die Detaildarstellung von
