Abstract
Description
Die Erfindung betrifft ein Schweißgerät zum Verbinden von überlappend verlegten, flächigen Dichtungsbahnen, mit einem von Rollen getragenen, angetriebenen Fahrgestell, mit einer Heizeinrichtung zum lokalen Erhitzen der Dichtungsbahnen, mit mindestens einer am Fahrgestell angeordneten Anpressrolle zum Zusammenpressen der heiß miteinander zu verbindenden Dichtungsbahnen.The The invention relates to a welding apparatus for joining from overlapping laid, flat geomembranes, with a driven by wheels, driven chassis, with a heater for locally heating the geomembranes, with at least one arranged on the chassis pressure roller for Clench the hot with each other to be joined geomembranes.
Derartige Schweißgeräte sind allgemein bekannt und im Einsatz und werden zum Verschweißen von Folien und Dichtungsbahnen, beispielsweise aus Kunststoff, entlang ihrer überlappenden Randbereiche verwendet. Die Dichtungsbahnen werden miteinander verbunden, indem sie an den Randbereichen. auf einander gegenüberliegenden Seiten lokal erhitzt und heiß zusammengepresst werden. Das Zusammenpressen erfolgt in der Regel mit mindestens einer an einem selbstfahrenden Fahrgestell des Schweißgerätes angeordneten Anpressrolle, die das Fahrgestell zusammen mit anderen Rollen trägt.such Welding machines are commonly known and in use and are used for welding Films and geomembranes, such as plastic, along their overlapping Edge areas used. The geomembranes are connected to each other, by being at the edge areas. on opposite sides Pages heated locally and hot pressed together become. The compression is usually done with at least one arranged on a self-propelled chassis of the welding machine Pressure roller, which carries the chassis together with other rollers.
Bekannte Schweißgeräte sind stabil und belasten die Anpressrolle mit einem Hauptanteil ihres Gewichtes, um einen hohen Anpressdruck für eine gute Schweißqualität sicherzustellen. Es ist üblich, die Anpressrolle auch als Antriebsrolle auszubilden, da sie fest gegen den Untergrund gepresst wird und damit auf grund ihres hohen Reibschlusses eine gute Krafteinleitung für die Vorwärtsbewegung sicherstellt. Eine solche angetriebene Anpressrolle wird bevorzugt an einem in Schweißrichtung hinteren Ende des Fahrgestells des Schweißgerätes, im Anschluss an die Heizeinrichtung zum Erhitzen der Dichtungsbahnen angeordnet.Known Welding machines are stable and load the pressure roller with a major part of their weight, for a high contact pressure for to ensure a good quality of welding. It is common that Pressure roller also form as a drive roller, as they firmly against the ground is pressed and thus due to their high friction a good force introduction for the forward movement ensures. Such a powered pressure roller is preferred at a welding direction Rear end of the chassis of the welder, following the heater arranged for heating the geomembranes.
Schweißgeräte der eingangs beschriebenen Art können auch zum Verschweißen von Bitumen-Dichtungsbahnen verwendet werden. Physikalisch gesehen gehört Bitumen zu den thermoplastischen Stoffen, d. h. seine Eigenschaften sind temperaturabhängig. Beim Abkühlen wird es hart, bei Erwärmung durchläuft es stufenlos alle Zustände von fest über zähflüssig bis dünnflüssig. Zum Schweißen der Bitumen-Dichtungsbahnen müssen diese erhitzt werden, bis das Bitumen an den zu verbindenden Stellen zumindest zähflüssig ist. Bei einem solchen Schweißvorgang kommt das Fahrgestell des Schweißgerätes häufig in Kontakt mit dem flüssigen Bitumen und wird durch diesen stark verschmutzt. Besonders betroffen davon sind die das Fahrgestell tragenden Rollen, wobei die die Bitumen-Dichtungsbahnen heiß gegeneinander pressende Anpressrolle besonders exponiert ist. Sie läuft unmittelbar auf der Überlappung, also im plastifizierten Bereich.Welding machines of the beginning described type can also for welding used by bitumen waterproofing membranes. Physically belongs Bitumen to the thermoplastic materials, d. H. its properties are temperature dependent. On cooling It gets hard when heated goes through it steplessly all states from firmly over viscous until thin. To the Welding the Bitumen waterproofing membranes must These are heated until the bitumen at the points to be joined at least viscous. In such a welding process The chassis of the welder often comes in contact with the liquid bitumen and is heavily polluted by this. Especially affected by it are the wheels carrying the chassis, wherein the bituminous membranes are hot against each other pressing pressure roller is particularly exposed. It runs immediately on the overlap, So in the plasticized area.
Die Qualität einer solchen Schweißverbindung ist abhängig von der Ebenheit einer Lauffläche der Anpressrolle, um die überlappenden Randbereiche über ihre Breite gleichmäßig zusammen zu pressen. Beim Schweißen von Bitumen-Dichtungsbahnen, bituminösen oder ähnlichen Dichtungsbahnen sowie anderen elastischen Dichtungsbahnen benetzt das plastifizierte Material die Lauffläche zunehmend und setzt sich ungleichmäßig verteilt dort fest. Damit keine Qualitätseinbußen entstehen, muss die Anpressrolle häufig manuell gereinigt werden. Die Reinigung ist aufwändig, da das Material fest an der Antriebsrolle haftet. Für die Reinigung ist damit eine längere Unterbrechung des Schweißvorgangs erforderlich, die unerwünscht ist.The quality such a welded joint depends on from the flatness of a tread the Press roller to the overlapping Edge areas over their width evenly together to squeeze. When welding of bituminous membranes, bituminous or similar Geomembranes and other elastic geomembranes wets the plasticized material increases the tread and settles distributed unevenly stuck there. So that no quality losses occur, the pressure roller must be frequent be cleaned manually. The cleaning is complex, because the material is solid adheres to the drive roller. For the cleaning is thus a longer one Interruption of the welding process necessary, the undesirable is.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Schweißgerät vorzuschlagen, das einen praktisch unterbrechungsfreien Betrieb ermöglicht.Of the The invention is therefore based on the object to propose a welding device, which allows a virtually uninterrupted operation.
Diese Aufgabe wird erfindungsgemäß durch ein Schweißgerät mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.These The object is achieved by a Welding machine with the Characteristics of claim 1 solved. Further advantageous embodiments are the subclaims remove.
Bei dem erfindungsgemäßen Schweißgerät ist am Fahrgestell eine zweite Anpressrolle als Ersatz-Anpressrolle angeordnet, die ohne Werkzeug gegen die mit einer angetriebenen Achse gekoppelten erste Antriebsrolle austauschbar ist. Damit ist bei Bedarf schnell und ohne Wartezeiten eine saubere, nicht mit Bitumen verschmutzte Anpressrolle zur Hand, die einfach von dem Fahrgestell lösbar ist. Nach dem Entfernen der verschmutzten ersten Anpressrolle von der Antriebsachse kann die zweite Anpressrolle montiert und auf der Antriebsachse fixiert werden.at the welding device according to the invention is on Chassis a second pressure roller arranged as a spare pressure roller, the without tool against the coupled with a driven axle first drive roller is interchangeable. This is fast if necessary and without waiting a clean, not contaminated with bitumen Pressure roller at hand, which is easily detachable from the chassis. To removing the soiled first pressure roller from the drive axle The second pressure roller can be mounted and mounted on the drive axle be fixed.
Zum Lösen der ersten und der zweiten Antriebsrolle von dem Fahrgestell des Schweißgerätes muss, ebenso wie zur Montage nach dem Austausch, kein Werkzeug benutzt werden. Somit kann der Austausch schnellstens erfolgen, ohne ein Werkzeug holen bzw. darauf warten zu müssen. Die Ersatz-Anpressrolle ist zweckmäßigerweise so auf dem Fahrgestell angeordnet, dass sie die Antriebsachse mit ihrem Hauptgewicht belastet, um die Traktion und den Anpressdruck der angetriebenen Anpressrolle, die das Fahrgestell bewegt und die Bitumen-Dichtungsbahnen zusammenpresst, zu optimieren.To the Solve the first and second drive roller of the chassis of the welding machine, as well as for assembly after replacement, no tools used become. Thus, the replacement can be done quickly, without a Get the tool or wait for it. The replacement pressure roller is expediently so arranged on the chassis that they use the drive axle their main weight loaded to the traction and the contact pressure the driven pressure roller that moves the chassis and the Bitumen waterproofing membranes presses to optimize.
Vorteilhafterweise weist das Fahrgestell eine Halterung für die zweite Anpressrolle auf, die vorzugsweise in Schweißrichtung hinter der ersten Antriebsrolle angeordnet ist. Bei in die Halterung eingesetzter zweiter Anpressrolle wird der Schwerpunkt der Schweißmaschine in Richtung der Antriebsachse verlagert und die Antriebsachse wie gewünscht zusätzlich belastet. Die Halterung kann eine Achse zum Aufschieben der Ersatz-Anpressrolle oder einen vorzugsweise zylindrischen Aufnahmeraum zur Aufnahme der zweiten Anpressrolle aufweisen.advantageously, the chassis has a holder for the second pressure roller, preferably in the welding direction is arranged behind the first drive roller. In the holder used second pressure roller is the focus of the welding machine shifted in the direction of the drive shaft and the drive axle as required additionally loaded. The holder may have an axis for pushing the replacement pressure roller or a preferably cylindrical receiving space for receiving having the second pressure roller.
In einer Ausführungsform der Erfindung ist die Anpressrolle auf der Antriebsachse durch eine Rändelschraube mit Bund fixiert. Dazu weist die Antriebsachse stirnseitig ein entsprechendes Innengewinde auf, in das die Rändelschraube einschraubbar ist. Die erste Antriebsrolle wird dadurch starr mit der Antriebsachse gekoppelt, wobei die Rändelschraube verhindert, dass sich die Anpressrolle axial verschiebt und/oder von der Antriebsachse abfällt. Die Antriebsrolle kann mittels der Rändelschraube von Hand montiert und demontiert werden.In an embodiment the invention is the pressure roller on the drive axle by a knurled screw fixed with collar.
