Abstract
Die Erfindung betrifft eine Vorrichtung zum Verschweißen von Schweißbahnen (S), umfassend: eine keilförmig ansteigende Abhebeeinrichtung (1) zum Abheben einer auf einem Untergrund ausgerollten Schweißbahn (S), eine Heizeinrichtung zum Erhitzen einer Unterseite der abgehobenen Schweißbahn (S) und eine Andrückeinrichtung (13) zum Andrücken der erhitzten Unterseite an eine auf dem Untergrund ausgerollte weitere Schweißbahn. Zur Verbesserung der Schweißqualität wird erfindungsgemäß vorgeschlagen, dass die Heizeinrichtung einen Flächenbrenner (3) umfasst, bei dem ein aus Luft und Gas gebildetes Brenngasgemisch in einer porösen Platte (25) flächig verteilt und nachfolgend in der Platte (25) oder an einer Oberfläche der Platte (25) verbrannt wird, so dass damit erzeugte Wärme über die gesamte Oberfläche ausgekoppelt wird.The invention relates to a device for welding welding paths (S), comprising: a wedge-shaped lifting device (1) for lifting a welding path (S) rolled out on a substrate, a heating device for heating a lower side of the lifted welding path (S) and a pressing device ( 13) for pressing the heated underside to an extended on the ground further welding path. To improve the quality of welding, the invention proposes that the heating device comprises a surface burner (3) in which a fuel gas mixture formed from air and gas is distributed in a porous plate (25) and subsequently in the plate (25) or on a surface of the plate (25) is burned, so that heat generated with it is decoupled over the entire surface.

Aufgabe der Erfindung ist es, die Nachteile nach dem Stand der Technik zu beseitigen. Es soll insbesondere eine Vorrichtung angegeben werden, mit der Schweißbahnen reproduzierbar und mit gleichbleibender Schweißqualität miteinander verschweißt werden können. The object of the invention is to eliminate the disadvantages of the prior art. In particular, a device is to be specified, with which welding paths can be welded together in a reproducible manner and with constant welding quality.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Merkmalen der Patentansprüche 2 bis 15. This object is solved by the features of patent claim 1. Advantageous embodiments of the invention will become apparent from the features of claims 2 to 15.
Nach Maßgabe der Erfindung wird vorgeschlagen, dass die Heizeinrichtung einen Flächenbrenner umfasst, bei dem ein aus Luft und Gas gebildetes Brenngasgemisch in einer porösen Platte flächig verteilt und nachfolgend in der Platte oder an einer Oberfläche der Platte verbrannt wird, so dass damit erzeugte Wärme über die gesamte Oberfläche der Platte gleichmäßig ausgekoppelt wird. According to the invention, it is proposed that the heating device comprises a surface burner in which a fuel gas mixture formed from air and gas is distributed in a porous plate and subsequently burned in the plate or on a surface of the plate, so that heat generated therewith entire surface of the plate is decoupled evenly.
Im Sinne der vorliegenden Erfindung wird unter dem Betriff "Platte" eine aus einem feuerfesten Material hergestellte Schicht verstanden. Die Schicht kann aus einem Stück aus einem keramischen Material hergestellt sein, welches eine offene Porosität oder kapillarartige Porenkanäle aufweist. Die Schicht kann aber auch aus einer Schüttung keramischer Partikel oder aus einem Drahtgewirk gebildet sein, welches zwischen zwei, mit Durchbrüchen versehenen Platten gehalten ist. Die "poröse Platte" im Sinne der Erfindung dient der gleichmäßigen Verteilung eines einströmenden Brenngasgemischs. For the purposes of the present invention, the term "plate" is understood to mean a layer made of a refractory material. The layer can be made in one piece from a ceramic material having an open porosity or capillary-like pore channels. The layer can also be formed from a bed of ceramic particles or a Drahtgewirk, which is held between two apertured plates. The "porous plate" within the meaning of the invention serves to uniformly distribute an incoming fuel gas mixture.
Unter dem Begriff "Oberfläche der Platte" wird eine Fläche verstanden, welche einer Eintrittsseite des Brenngasgemischs gegenüberliegt. An der Oberfläche wird die bei der Verbrennung erzeugte Wärme in Richtung der Unterseite der Schweißbahn ausgekoppelt. Unter dem Begriff "gesamte Oberfläche" wird diejenige Oberfläche der Platte verstanden, welche nicht, z. B. randlich zu Montagezwecken, verdeckt ist. Die "gesamte Oberfläche" der Platte beträgt üblicherweise zumindest 80%, vorzugsweise 90%, einer geometrischen Oberfläche der Platte. The term "surface of the plate" is understood to mean a surface which is opposite to an inlet side of the fuel gas mixture. On the surface, the heat generated during combustion is coupled out in the direction of the underside of the welding path. The term "entire surface" is understood that surface of the plate which does not, for. B. marginal for assembly purposes, is covered. The "total surface area" of the plate is usually at least 80%, preferably 90%, of a geometric surface of the plate.
Der Begriff "Flächenbrenner" umfasst sogenannte "Volumenbrenner" sowie "Oberflächenbrenner". Bei Volumenbrennern wird das in der porösen Platte verteilte Brenngasgemisch innerhalb des porösen Volumens an der Oberfläche der Poren verbrannt. Ein Volumenbrenner strahlt über die Oberfläche Infrarotstrahlung ab. Abgesehen davon treten aus der Oberfläche der Platte heiße Abgase aus. Bei einem Oberflächenbrenner ist dagegen die Platte mit kapillarartigen Kanälen durchsetzt, welche an der Oberfläche münden. Die Verbrennung des Brenngases findet an der Oberfläche an der Mündung der kapillarartigen Kanäle statt. Ein Durchmesser der kapillarartigen Kanäle ist so gewählt, dass ein Rückschlagen der Flammen durch die Platte unmöglich ist. Auch bei einem Oberflächenbrenner wird die Wärme über die gesamte Oberfläche gleichmäßig ausgekoppelt. – Sowohl ein Volumenbrenner als auch ein Oberflächenbrenner ermöglichen über eine große Fläche hinweg einen gleichmäßigen Wärmeeintrag auf ein zu erwärmendes Gut. Mit Flächenbrennern kann eine besonders umweltfreundliche und effiziente Verbrennung des Brenngases erreicht werden. Insbesondere kann die Bildung von schädlichen Stickoxiden stark herabgesetzt werden. The term "surface burner" includes so-called "volume burners" and "surface burners". In volume burners, the fuel gas mixture distributed in the porous plate is burned within the porous volume at the surface of the pores. A volume burner emits infrared radiation across the surface. Apart from that, hot exhaust gases escape from the surface of the plate. In a surface burner, however, the plate is interspersed with capillary-like channels, which open at the surface. The burning of the Fuel gas takes place on the surface at the mouth of the capillary-like channels. A diameter of the capillary-like channels is chosen so that a flashback of the flame through the plate is impossible. Even with a surface burner, the heat is decoupled uniformly over the entire surface. - Both a volume burner and a surface burner allow a uniform heat input over a large area to a good to be heated. With surface burners, a particularly environmentally friendly and efficient combustion of the fuel gas can be achieved. In particular, the formation of harmful nitrogen oxides can be greatly reduced.
Unter dem Begriff "Schweißbahn" wird ein bahnförmiges Material verstanden, welches zumindest an seiner einen Seite mit einer aufschmelzbaren Schicht beschichtet ist, welche sich beim Abkühlen wieder verfestigt. Bei der Schweißbahn kann es sich beispielsweise um eine Bitumenbahn, eine mit einem Thermoplasten beschichtete Kunststoffbahn oder dgl. handeln. Eine Schweißbahn nach dem Gegenstand der Erfindung kann mit einer Unterlage verklebt oder verschweißt werden. Bei der Unterlage kann es sich um eine weitere Schweißbahn handeln. The term "welding path" is understood to mean a web-shaped material which is coated on at least one side thereof with a meltable layer which solidifies again on cooling. The welding path can be, for example, a bituminous sheet, a plastic sheet coated with a thermoplastic or the like. A welding line according to the subject invention can be glued or welded to a substrate. The base may be another welding track.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist die poröse Platte auf offenporigem SiSiC hergestellt. In diesem Fall handelt es sich bei dem Flächenbrenner um einen Volumenbrenner. According to an advantageous embodiment of the invention, the porous plate is made on open-pore SiSiC. In this case, the area burner is a volume burner.
Nach einer alternativen Ausgestaltung ist die poröse Platte aus Al2O3 hergestellt. In diesem Fall können die Poren als durchgängige Kapillaren ausgebildet sein. Es handelt sich hierbei um einen Flächenbrenner. Selbstverständlich kann die poröse Platte auch aus anderen geeigneten keramischen Materialien hergestellt sein. According to an alternative embodiment, the porous plate is made of Al 2 O 3 . In this case, the pores may be formed as continuous capillaries. It is a surface burner. Of course, the porous plate may also be made of other suitable ceramic materials.
Nach einer weiteren Ausgestaltung umfasst die Heizeinrichtung eine Mischeinrichtung zum Mischen von Gas und Luft. Die Mischeinrichtung umfasst insbesondere ein Gebläse zum Zuführen von Luft. Mit der Mischeinrichtung ist vorteilhafterweise eine Luftzahl und/oder ein Massestrom des dem Flächenbrenner zugeführten Brenngasgemischs steuerbar. Damit lässt sich die Leistung des Flächenbrenners modulieren. Die Leistung des Flächenbrenners kann an die jeweils zu verschweißende Schweißbahn und/oder die Außentemperatur angepasst werden. According to a further embodiment, the heating device comprises a mixing device for mixing gas and air. The mixing device comprises in particular a fan for supplying air. With the mixing device is advantageously an air ratio and / or a mass flow of the surface burner supplied fuel gas mixture controllable. This allows the performance of the surface burner to be modulated. The performance of the surface burner can be adapted to the respective welding path to be welded and / or the outside temperature.
Nach einer weiteren Ausgestaltung der Erfindung ist der Flächenbrenner aus mehreren separat zu- und abschaltbaren Flächenbrennereinheiten gebildet. Der Flächenbrenner erstreckt sich vorteilhafterweise über die gesamte Breite einer zu verschweißenden Schweißbahn. Eine Breite des Flächenbrenners kann somit im Bereich von 80 bis 130 cm liegen. Über die Breite hinweg kann der Flächenbrenner aus mehreren Flächenbrennereinheiten gebildet sein, welche beispielsweise jeweils eine weitere Breite von 20 bis 30 cm haben. Indem derartige Flächenbrennereinheiten separat zu- und abschaltbar sind, kann eine wirksame Breite des Flächenbrenners an die Breite der jeweils zu verschweißenden Schweißbahn angepasst werden. Mit der vorgeschlagenen Vorrichtung ist es sowohl möglich, eine Schweißbahn vollflächig mit einer darunterliegenden weiteren Schweißbahn zu verschweißen als auch eine Schweißbahn lediglich randlich mit einer darunterliegenden weiteren Schweißbahn zu verschweißen. Im letzteren Fall kann beispielsweise nur eine Flächenbrennereinheit betrieben werden. Zum vollflächigen Verschweißen werden so viele nebeneinanderliegende Flächenbrennereinheiten betrieben, dass deren wirksame Breite zumindest der Breite der zu verschweißenden Schweißbahn entspricht. According to a further embodiment of the invention, the surface burner is formed from a plurality of separately connectable and disconnectable surface burner units. The surface burner advantageously extends over the entire width of a welding path to be welded. A width of the surface burner can thus be in the range of 80 to 130 cm. Across the width of the surface burner can be formed of a plurality of surface burner units, which, for example, each have a further width of 20 to 30 cm. By such surface burner units are separately switched on and off, an effective width of the surface burner can be adapted to the width of the respective welding path to be welded. With the proposed device, it is both possible to weld a welding path over its entire surface to an underlying further welding path and also to weld a welding path only marginally with an underlying further welding path. In the latter case, for example, only a surface burner unit can be operated. For full-surface welding as many adjacent surface burner units are operated so that their effective width corresponds at least to the width of the welding path to be welded.
Nach einer weiteren vorteilhaften Ausgestaltung umfasst die Andrückeinrichtung mehrere unabhängig voneinander um eine Schwenkachse schwenkbeweglich angebrachte Walzen. Die Mehrzahl der nebeneinander schwenkbeweglich angebrachten Walzen ermöglicht auch bei einem unebenen Untergrund die Aufbringung einer gleichmäßigen Andrückkraft über die gesamte Breite der Schweißbahn. Damit kann über die gesamte Breite der Schweißbahn hinweg eine gleichförmige und durchgehende Verschweißung mit einer darunterliegenden weiteren Schweißbahn erreicht werden. According to a further advantageous embodiment, the pressing device comprises a plurality of independent of each other pivotally mounted about a pivot axis rollers. The majority of juxtaposed pivotally mounted rollers allows even with an uneven ground, the application of a uniform pressing force over the entire width of the weld path. This can be achieved across the entire width of the welding path away a uniform and continuous welding with an underlying further welding track.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist eine elektrische Antriebseinrichtung zum Antrieb der Walzen vorgesehen. Damit ist es möglich, die Vorrichtung selbstfahrend mit einer konstanten Geschwindigkeit zu bewegen. Das trägt weiter dazu bei, eine gleichbleibende Schweißqualität zu gewährleisten. Die elektrische Antriebseinrichtung kann steuerbar sein, so dass eine Fahrgeschwindigkeit der Vorrichtung variiert werden kann. According to a further advantageous embodiment of the invention, an electric drive device for driving the rollers is provided. This makes it possible to move the device self-propelled at a constant speed. This further helps to ensure consistent welding quality. The electric drive device can be controllable, so that a travel speed of the device can be varied.
Zweckmäßigerweise sind Achsen der Walzen schwenkbeweglich miteinander gekoppelt. Die Achsen der Walzen sind des Weiteren vorteilhafterweise antriebsmäßig mit einer Welle der Antriebseinrichtung gekoppelt. Das ermöglicht einen Antrieb der Walzen auch dann, wenn sie relativ zueinander um unterschiedliche Schwenkwinkel verschwenkt werden. Das Verschwenken der Walzen kann entgegen der Rückstellkraft zumindest eines Federelements bzw. eines elastischen Elements erfolgen. Appropriately, axes of the rollers are pivotally coupled together. The axes of the rollers are further advantageously drivingly coupled to a shaft of the drive means. This allows a drive of the rollers even if they are pivoted relative to each other by different pivoting angles. The pivoting of the rollers can take place counter to the restoring force of at least one spring element or an elastic element.
Nach einer weiteren Ausgestaltung der Erfindung umfasst die Abhebeeinrichtung ein den Flächenbrenner teilweise umgebendes Gehäuse, von dem sich keilförmig verjüngende Stege erstrecken. Die Stege sind parallel zueinander angeordnet und verlaufen im Wesentlichen vertikal vom Gehäuse in Richtung eines Frontbereichs bzw. Vorderendes der Vorrichtung. Ausschließlich in einem Frontbereich der Stege ist ein Abhebeblech vorgesehen. Das Abhebeblech ist auf den Stegen abgestützt und fest damit verbunden. Zwischen dem Abhebeblech und dem Gehäuse ist die Abhebeeinrichtung lediglich durch die Stege gebildet. Infolgedessen wird vorteilhafterweise eine Wärmeentkopplung zwischen dem Abhebeblech und dem Gehäuse erreicht. Es kann also nicht dazu kommen, dass eine durch das Abhebeblech abgehobene Schweißbahn bereits durch das Abhebeblech oder die Stege teilweise aufgeschmolzen wird und infolgedessen unerwünschterweise mit der Abhebeeinrichtung verklebt. According to a further embodiment of the invention, the Abhebeeinrichtung comprises a surface burner partially surrounding housing from which wedge-shaped tapered webs extend. The webs are arranged parallel to one another and extend substantially vertically from the housing in the direction of a front region or front end of the housing Contraption. Only in a front region of the webs a lift-off plate is provided. The lift-off plate is supported on the webs and firmly connected. Between the Abhebeblech and the housing Abhebeeinrichtung is formed only by the webs. As a result, a heat decoupling between the lifting plate and the housing is advantageously achieved. It can therefore not happen that a raised by the Abhebeblech welding path is already partially melted by the Abhebeblech or the webs and as a result, undesirably bonded to the Abhebeeinrichtung.
Nach einer weiteren vorteilhaften Ausgestaltung sind zwischen dem Abhebeblech und dem Gehäuse zwei Frontrollen jeweils zwischen zwei benachbarten Stegen zum verfahrbaren Abstützen der Abhebeeinrichtung gehalten. Im Heckbereich ist in Bewegungsrichtung nachlaufend der Welle eine schwenkbare Heckrolle vorgesehen. Infolgedessen wird die Vorrichtung also auf den beiden Frontrollen und der einen Heckrolle abgestützt, welche um eine vertikale Achse schwenkbar ist. Das ermöglicht ein Lenken der Vorrichtung. According to a further advantageous embodiment, two front rollers are held in each case between two adjacent webs for movably supporting the lifting device between the lift-off plate and the housing. In the rear area, a pivotable rear roller is provided in the direction of movement of the shaft. As a result, the device is thus supported on the two front rollers and a rear roller, which is pivotable about a vertical axis. This allows the device to be steered.
