Device for welding the bottom of round bags to the associated ones Tubular bag part The invention relates to a device for welding the bottom of round bags to the associated tubular bag part by means of a hot air welding torch.

Es ist eine Vorrichtung zum Herstellen eines Sackes mit rundem Boden und Mantel aus thermoplastischen Kunststoffolien bekannt, bei der ein drehbarer Rundtisch für die Auflage der Folie vorgesehen ist und der Rundtisch durch Friktion in Abhängigkeit von einem angetriebenen Anpreßrad gedreht wird. It is a device for making a sack with a round bottom and jacket made of thermoplastic plastic films known, in which a rotatable Rotary table is provided for the support of the film and the rotary table by friction is rotated depending on a driven pressure wheel.

Hierbei ist die Anordnung so getroffen, daß von der Seite geschweißt wird. Dabei ist es erforderlich, die zu verschweißenden Teile zusätzlich festzuhalten und hilfsweise Klebestreifen zu verwenden. Für die Zustellung des Rades, mindestens dessen Rand erwärmt wird, ist eine Kurbel zu betätigen. Hierbei bedarf es einer Einarbeitung und eines Feingefühls der handhabenden Person, den richtigen Anpreßdruck herauszufinden. Bei Verschweißen von Behältern aus thermoplastischem Material ist es an sich bekannt, Heißluftschweißbrenner zu verwenden.Here the arrangement is made so that welded from the side will. It is necessary to additionally hold the parts to be welded and use adhesive strips as an alternative. For the delivery of the bike, at least the edge of which is heated, a crank must be operated. This requires one Training and sensitivity of the person handling it, the right contact pressure to find out. When welding containers made of thermoplastic material it is known per se to use hot air welding torches.

Das Anschweißen des Bodens von Rundbeuteln an den zugehörigen Schlauchbeutelteil erfolgt gemäß der Erfindung in der Weise, daß das Anpreßrad als Friktionsrolle von oben auf der Tischfläche unter Gewicht und auf der vorangehend erwärmten Randzone der Naht aufliegt, wobei die Friktionsrolle mittels des Motorgewichtes auf der zu schweißenden Naht lastet. Vorteilhaft ist der Motor an einem schwenkbaren Hebelarm angeordnet, wobei die Friktionsrolle radial bzw. nahezu radial auf dem Rundtisch aufliegt. Der Heißgasschweißbrenner ist hierbei mit dem Hebelarm verbunden. The welding of the bottom of round bags to the associated tubular bag part takes place according to the invention in such a way that the pressure wheel as a friction roller of on top of the table surface under weight and on the previously heated edge zone the seam rests, with the friction roller on the closed by means of the weight of the motor welding seam weighs down. The motor on a pivotable lever arm is advantageous arranged, with the friction roller radially or almost radially on the rotary table rests. The hot gas welding torch is connected to the lever arm.

Durch das erfindungsgemäße Schweißen von oben sind besondere Mittel zum Festhalten entbehrlich, außerdem wird der Schweißdruck bzw. der Anpreßdruck unmittelbar durch das Eigengewicht des Motors erzeugt. Eine besondere Vorrichtung für das Anpressen entfällt. Es ist die Gewähr gegeben, daß infolge des selbsttätig wirkenden Anpreßdruckes dieser für alle zu verschweißenden Beutel konstant bleibt. The inventive welding from above are special means to hold on unnecessary, in addition, the welding pressure or the contact pressure generated directly by the weight of the engine. A special device for pressing is not required. There is a guarantee that as a result of the automatic acting contact pressure this remains constant for all bags to be welded.

Zugleich erfolgt der Antrieb des lose drehbaren Rundtisches unmittelbar durch die Friktionsrolle des Motors, die dadurch die Umfangsgeschwindigkeit bestimmt. Man erzielt auf diese Weise unabhängig von dem Durchmesser des Rundtisches eine gleichbleibende Umfangsgeschwindigkeit. Dies ist von Bedeutung, damit bei gleicher Foliendicke, aber verschiedenen Schlauchdurchmessern, stets dieselben Ergebnisse erzielt werden können. Weiterhin ist eine gleichmäßig bleibende einwandfreie und saubere rundgehende Schweißnaht gewährleistet.At the same time, the loosely rotatable rotary table is driven directly by the friction roller of the motor, which thereby determines the peripheral speed. In this way, regardless of the diameter of the rotary table, a constant peripheral speed. This is important for the same Film thickness, but different tube diameters, always the same results can be achieved. Furthermore, a consistent and flawless clean all-round weld seam guaranteed.

Vorteilhaft ist der den Motor tragende Hebelarm mittels eines Schwenkarmes an einer Säule angeordnet, deren Fuß mit dem Ständer längs einer Führung verschiebbar ist. Der Schwenkarm kann drehbar um die Säule sein. Ferner können mehrere Rundtische auf dem Schwenkkreis des Schwenkarmes vorgesehen sein. The lever arm carrying the motor by means of a swivel arm is advantageous arranged on a column, the foot of which can be displaced with the stand along a guide is. The swivel arm can be rotatable around the column. Furthermore, several rotary tables be provided on the swivel circle of the swivel arm.

Das Verschweißen erfolgt in der Weise, daß der Schlauchzuschnitt 11 über den Rundtisch 2 gezogen wird. Darauf legt man die Bodenfolie 12 auf, die durch eine Platte bis auf die zu bildende Schweißnaht abgedeckt sein kann. Die Verschweißung erfolgt vorzugsweise mit Heißluft, wobei der Arbeitsablauf selbsttätig ist. Durch den Heißluftschweißbrenner wird die Folie längs der zu bildenden Naht plastifiziert. Im gleichen Arbeitsgang erfolgt die Pressung durch die Friktionsrolle 6, die mit dem Gewicht des Motors 3 auf der Naht lastet. Die Vorschubgeschwindigkeit wird durch den Umlauf der Friktionsrolle 6 bestimmt. The welding takes place in such a way that the hose blank 11 is pulled over the rotary table 2. Then you put the bottom sheet 12 on, the can be covered by a plate except for the weld to be formed. The welding preferably takes place with hot air, the workflow being automatic. By The film is plasticized along the seam to be formed using the hot air welding torch. In the same operation, the pressing is done by the friction roller 6, which is with the weight of the motor 3 rests on the seam.
