Ultrasonic welding machine
Die Erfindung betrifft ein UltraschalIschweißgerät zum kontinuierlichen Verschweißen einander überlappender Abdichtungsbahnen, wobei zwischen die sich überlappenden Bahnenränder ein keilförmiges Werkzeug gegen die Schweißflächen wirkt, das sich hin- und hergehend bewegt und mit den Schweißflächen zumindestens intermittierend reibungsschlüssige Berührung hat. Das UltraschalIschweißgerät entspricht im wesentlichen Aufbau den bekannten HeizkeiIschweißgeräten. Bei HeizkeiIschweißgeräten überträgt der Heizkeil Wärme auf die Schweißflächen. Das geschieht, indem die Schweißflächen der miteinander zu verschweißenden Bahnenränder an dem Keizkeil entlang geführt werden. Dabei plastifizieren die Schweißflachen. Nach Verlassen des Heizkeiles gelangen die Bahnenränder in den Spalt eines Andruckrollenpaares. Dort werden die plastifizierten Schweißflachen aneinandergedrückt.The invention relates to an ultrasonic welding device for continuously welding overlapping sealing sheets, whereby a wedge-shaped tool acts between the overlapping sheet edges against the welding surfaces, which moves back and forth and has at least intermittent frictional contact with the welding surfaces. The ultrasonic welding device is essentially the same design as the known hot wedge welding devices. In hot wedge welding devices, the hot wedge transfers heat to the welding surfaces. This happens when the welding surfaces of the sheet edges to be welded together are guided along the hot wedge. The welding surfaces plasticize in the process. After leaving the hot wedge, the sheet edges enter the gap of a pair of pressure rollers. There, the plasticized welding surfaces are pressed together.
Beim Ultraschallschweißen wird zwar auch ein keilförmiges Werkzeug zum Plastifizieren der Schweißflächen verwendet. Dieses Werkzeug ist jedoch nicht erhitzt. Vielmehr wird mittels Ultraschall und Reibung die Schweißfläche plastifiziert.In ultrasonic welding, a wedge-shaped tool is also used to plasticize the welding surfaces. However, this tool is not heated. Instead, the welding surface is plasticized using ultrasound and friction.
Vom UltraschalIschweißgerät hat man erwartet, daß es die Heiikeilschweißgeräte ablöst. Das ist bislang jedoch nicht eingetreten, weil sich die UltraschalIschweißgeräte als unzuverlässig erwiesen haben. Es kam zwar nicht zu Betriebsausfällen des Schweißgerätes, aber die Schweißnähte haben sich teilweise als unzulänglich erwiesen. It was expected that the ultrasonic welding machine would replace the hot wedge welding machines. However, this has not happened yet because the ultrasonic welding machines have proven to be unreliable. Although the welding machine has not broken down, the welds have proved to be inadequate in some cases.
Der Erfindung Hegt daher die Aufgabe zugrunde, UltraschalIschweißgeräte zu verbessern. Dabei geht die Erfindung vcn der Überlegung aus, daß die Schweißgeräte einen sehr engen Toleranzbereich erarbeiten, der zum Teil auch dadurch überschritten werden kann, daß Schmutzpartikei und Feuchtigkeit die Schwei3fIache&eegr; verunreinigen. Nach der Erfindung wird das dadurch vermieden, daß In SchweibrIchtung vor dem Schweißspalt ein Gebläse vorgesehen 1st.The invention is therefore based on the task of improving ultrasonic welding devices. The invention is based on the consideration that welding devices have a very narrow tolerance range, which can be partially exceeded by dirt particles and moisture contaminating the welding surface. According to the invention, this is avoided by providing a fan in the welding direction in front of the welding gap.

Das Gebläse arbeitet wahlweise mit Kaltluft oder Warmluft. Die Warmluft kann genutzt werden, um die SchwelßflSehen auf eine Temperatur zu bringen, bei der das Ultraschallwerkzeug optimal wirkt.The blower operates either with cold air or warm air. The warm air can be used to bring the welding surfaces to a temperature at which the ultrasonic tool works optimally.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. An embodiment of the invention is shown in the drawing.
Zu einem Ul traschall schweißgerät gehören neben einem keilförmigen Werkzeug 1 Andruckrollen 2 und 3. Im Betriebsfall werden die miteinander zu verbindenden Bahnenränder an dem Werkzeug 1 vorbei in den Spalt zwischen Andruckwalzen 2 und 3 geführt. Dabei wird ein Bahnenrand 4 oben und ein Bahnenrand 5 unten geführt. In dem Spalt zwischen den Andruckrollen 2 und 3, der zugleich der Schweißspalt ist, treffen die Bahnenränder 4 und 5 aufeinander. Dabei wirkt das keilförmige Werkzeug 1 mit seiner Spitze gegen die Schweißflächen und plastifiziert die Schweißflächen aufgrund seiner Ultraschallschwingung und besonderer Reibungsverhältnisse. Die besonderen Reibungsverhältnisse werden durch eine stark profilierte Werkzeugoberfläche erreicht. Besonders geeignet ist eine kreuzweise Riffelung. An ultrasonic welding device includes a wedge-shaped tool 1 and pressure rollers 2 and 3. During operation, the web edges to be joined are guided past the tool 1 into the gap between pressure rollers 2 and 3. A web edge 4 is guided at the top and a web edge 5 at the bottom. The web edges 4 and 5 meet in the gap between the pressure rollers 2 and 3, which is also the welding gap. The wedge-shaped tool 1 acts with its tip against the welding surfaces and plasticizes the welding surfaces due to its ultrasonic vibration and special friction conditions. The special friction conditions are achieved by a strongly profiled tool surface. A cross-shaped corrugation is particularly suitable.
Das keilförmige Werkzeug des Ultraschal Ischweißgerätes ist in der Spitze aus Gründen der Funktionalität ausgenommen. In den mit 6 bezeichneten Ausnehmungen sind Düsen 7 angeordnet. Wie aus Fig. 3 ersichtlich ist, werden die Düsen 7 durch einen gabelförmigen Hohlkörper gebildet, der das Werkzeug 1 im Bereich der Ausnehmungen 6 mH einem für die Werkzeugbewegung ausreichenden Spiel umfaßt urr* zu den Bahnenrändern 4 und 5 hin mit Austrittsöffnungen bzw. Düsenöffnungen versehen ist.The wedge-shaped tool of the ultrasonic welding device is recessed at the tip for reasons of functionality. Nozzles 7 are arranged in the recesses marked 6. As can be seen from Fig. 3, the nozzles 7 are formed by a fork-shaped hollow body which surrounds the tool 1 in the area of the recesses 6 with a clearance sufficient for the tool movement and is provided with outlet openings or nozzle openings towards the web edges 4 and 5.
Im Betriebsfall wird der Hohlkörper mit Kaltluft aus einem nicht dargestellten Gebläse beaufschlagt. Das Gebläse ist an beliebiger Stelle am Schweißgerätegehäuse befestigt und über eine flexible Schlauchleitung mit dem die Düsen 7 bildenden Hohlkörper verbunden.During operation, the hollow body is exposed to cold air from a blower (not shown). The blower is attached to any position on the welding machine housing and is connected to the hollow body forming the nozzles 7 via a flexible hose line.
Die aus den Düsenöffnungen des Hohlkörpers austretende Luft bläst die Schweißflächen der Bahnenränder 4 und 5 sauber und ggf. trocken, bevor die Schwelßflachen mit dem Werkzeug 1 1n Berührung kommen.The air exiting from the nozzle openings of the hollow body blows the welding surfaces of the web edges 4 and 5 clean and, if necessary, dry before the welding surfaces come into contact with the tool 1 1n.
Der Düsen 7 bildende Hohlkörper 1st an einem Gehäuseteil bzw. Gestänge des Schweißgerätes gehalten, an dem auch die Rollenhalterung 8 für die Andruckrollen 2 und 3 befestigt 1st. Die Rollenhalterung 8 greift gemäß Fig. 2 S-förmig um den Bahnenrand 4 herum, durch den Spalt zwischen den Bahnenrändern 4 und 5 und danach um den Bahnenrand 5 herum.The hollow body 1 forming the nozzles 7 is held on a housing part or rod of the welding device, to which the roller holder 8 for the pressure rollers 2 and 3 is also attached. The roller holder 8 grips in an S-shape around the web edge 4 as shown in Fig. 2, through the gap between the web edges 4 and 5 and then around the web edge 5.
