Description

Omniplast GmbH & Co. KGOmniplast GmbH & Co. KG

Die Erfindung betrifft eine Gerät zum Schweißen von Kunststoffdichtungsbahnen insbesondere für Dichtungsbahnen im Grundwasserschutzbereich .The invention relates to a device for welding plastic sealing sheets, in particular for sealing sheets in the groundwater protection sector.

Kunststoffbahnen werden als Abdichtmittel für großflächige Auffangwannen und Auffangräume für die Lagerung wassergefährdender Medien verwendet.Plastic sheets are used as a sealing agent for large-area collecting trays and collection rooms for the storage of water-polluting media.

Als Abdichtungsmaterial kommen vorwiegend Bahnen aus Niederdruck - Polyethylen in Frage. Die einzelnen Bahnen werden durch Schweißung verbunden.Low-pressure polyethylene sheets are the main sealing material used. The individual sheets are connected by welding.

Zum Einsatz kommen Heizkeil- oder Heißgas-Schweißautomaten mit ( automatischer Registrierung der Schweißparameter.Hot wedge or hot gas welding machines with automatic registration of the welding parameters are used.

Beim Schweißen wird der überlappte Schweißbereich durch Heizkeile oder Heißgasdüsen erhitzt und durch ein Walzenpaar direkt anschließend zusammengepreßt. Die Naht besteht somit aus artgleichem Material, zusätzlich kann eine Extrusionsnaht gelegt werden.During welding, the overlapped welding area is heated by heating wedges or hot gas nozzles and then immediately pressed together by a pair of rollers. The seam is therefore made of the same material; an extrusion seam can also be laid.

Der Abstand und damit der Anpreßdruck des Walzenpaares ist zum Erreichen der geforderten hohen Schweißgüte von entscheidender Bedeutung.The distance and thus the contact pressure of the roller pair is of crucial importance for achieving the required high welding quality.

Bei den bekannten Schweißgeräten erfolgt die Zustellung des Walzenpaares über Exzenter, hydraulisch oder pneumatisch.In the known welding machines, the roller pair is fed via eccentrics, hydraulically or pneumatically.

Die Zustellung über einen Exzenter kann nicht feinfühlig genug durchgeführt werden. Beim Einsatz von Hydraulik oder Pneumatik ist ein Nachfedern der Zustellung nicht auszuschließen. Zusätzlich zu dem Schweißgerät wird auf der Baustelle auch noch ein Druckerzeuger benötigt.The delivery via an eccentric cannot be carried out sensitively enough. When using hydraulics or pneumatics, it cannot be ruled out that the delivery will spring back. In addition to the welding device, a pressure generator is also required on the construction site.

Das erfindungsgemäße Schweißgerät besitzt eine Zustellung des Walzenpaares über eine Gewindespindel mit Mutter, die über einen Getriebemotor stufenlos erfolgt. Durch die selbsthemmende Wirkung ist die vorgegebene Einstellung konstant. Durch diese Anordnung kann auch während des Schweißvorgangs die Verstellung des Walzenspalts von Hand mit einem Schalter oder programmgesteuert durchgeführt werden.The welding device according to the invention has a feed of the roller pair via a threaded spindle with nut, which is carried out continuously via a gear motor. The self-locking effect ensures that the specified setting is constant. This arrangement also allows the roller gap to be adjusted manually with a switch or by program control during the welding process.

Zwischen der festen Rolle 1 und der verstellbaren Rolle 2 werden die zu verschweißenden Dichtungsbahnen 7 und 8 hindurch transportiert.The sealing sheets 7 and 8 to be welded are transported between the fixed roller 1 and the adjustable roller 2.

Zur Verstellung des Walzenspaltes dreht der Getriebemotor die angeflanschte Gewindespindel 5 und hebt bzw. senkt die Mutter 4. Die Travese 3 die die verstellbare Rolle 2 trägt, drückt über eine nicht dargestellte Feder gegen die Kalotte 9 am unteren Ende der Mutter 4. Die Travese 3 ist in eine nicht dagestellten Führung vertikal verstellbar am Maschinengestell befestigt. To adjust the roller gap, the gear motor turns the flanged threaded spindle 5 and raises or lowers the nut 4. The traverse 3, which carries the adjustable roller 2, presses against the cap 9 at the lower end of the nut 4 via a spring (not shown). The traverse 3 is attached to the machine frame in a guide (not shown) that can be adjusted vertically.
