Description
Vorrichtung zum kontinuierlichen Verschweißen von Kunststoffolien Zum Verschweißen von Folien sind bereits Vorrichtungen bekannt, bei welchen endlose, verstell- und heizbare Bänder die Folien an Walzen drücken, wobei die Rollen und Bänder so angeordnet sind, daß die ankommenden Folien von .der Walze und den Bändern aufgenommen werden. Bei diesen bekannten Vorrichtungen werden die Folien in kaltem Zustand aufeinandergelegt und dann erst erwärmt. Die dabei erhaltene Verschweißung der Folien befriedigt jedoch im allgemeinen nicht, da die Verteilung der Wärme innerhalb der einzelnen Folien ungleichmäßig ist.Device for the continuous welding of plastic films Devices for welding foils are already known in which endless, adjustable and heated belts press the foils against rollers, the rollers and Belts are arranged so that the incoming foils from the roller and the belts be included. In these known devices, the films are in cold Condition placed on top of one another and only then warmed up. The weld obtained in this way However, the foils are generally unsatisfactory because of the distribution of heat within of the individual foils is uneven.
Gegenstand der Erfindung ist eine Vorrichtung zum kontinuierlichen Verschweißen von Kunststofffolien, bei der die oben angegebenen Mängel nicht auftreten und die durch eine derartige Anordnung von mehreren, zahlenmäßig den miteinander zu verschweißenden Einzelfolien, entsprechenden Walzen-Band-Einrichtungen gekennzeichnet ist, so daß jede Einzelfolie der für sie vorgesehenen Walzen-Band-Einrichtung von einer jeweils unterhalb der zugehörigen Walze auf einem einfahrbaren Wagen angeordneten Foliennrolle zuführbar und nacheinander mit der vorhergehenden Folie bzw. dem vorhergehenden Fohenverband in an sich bekannter Weise durch auf der Oberseite der Walzen angeordnete Geigenwalzen lzen verschweißbar ist.The invention is a device for continuous Welding of plastic films in which the above-mentioned defects do not occur and by such an arrangement of several, numerically with each other Individual foils to be welded, corresponding roller-belt devices marked is, so that each individual film of the roller belt device provided for it one arranged below the associated roller on a retractable carriage Foil roll can be fed in and one after the other with the previous foil or the previous one Fohenverband in a manner known per se by arranged on the top of the rollers Violin rolls can be welded.
Gemäß einem weiteren Merkmal der Erfindung sind die Folienrollen zum Auswechseln in eine Seitenstellung um.'hängbar.According to a further feature of the invention, the film rolls are for Can be changed to a side position.
Außerdem können erfindungsgemäß zwischen den einzelnen Walzen-Band-Einrichtungen Heizorgane zum Zwischenheizer der hierbei frei laufenden Folien bzw. des Folienverbandes angeordnet sein.In addition, according to the invention, between the individual roller-belt devices Heating elements for the intermediate heater of the freely running films or the film bandage be arranged.
Die Vorrichtung gewährleistet eine sehr ;gleichmäßige Verteilung der Wärme innerhalb der einzelnen Folien, so daß eine wesentlich bessere Verschweißung der Folien erzielt wird.The device ensures a very even distribution of the Heat inside the individual foils, so that a much better weld of the foils is achieved.
Dies ist insbesondere bei der Verschweißung mehrerer Folien zu einem Fußbodenbelag vorn; besonderer , Bedeutung, da .die obere, die Oberschicht des Belags bildende Folie meist ganz andere physikalische Eigenschaften besitzt als die darunterliegenden Schichten.This is particularly important when welding several foils into one Floor covering in front; special, importance, because the upper, the upper layer of the pavement The film that forms it usually has very different physical properties than the underlying film Layers.
Außerdem ist dadurch, daß die Folienrollen auf einfahrbaren Wagen unterhalb der Walzen angeord- , net sind und zum Auswechseln in eine Seitenstellung umh'ängbar sind, eine sehr einfache Handhabung der Vorrichtung :gemäß der Erfindung Die Vorrichtung gemäß der Erfindung ist an Hand der Zeichnung näher erläutert.In addition, the fact that the film rolls on retractable trolleys are arranged underneath the rollers and can be exchanged in a lateral position are umh'ängbar, a very simple handling of the device: according to the invention The device according to the invention is explained in more detail with reference to the drawing.
Mit A sind die in einfahrbaren Wagen angeordneten Folienrohen, die zum Auswechseln, in eine Seitenstellung B umhängbar sind, bezeichnet. Von den Rollen A werden die zu verschweißenden Folien C über entsprechende Umlenkrollen über die Heizwalzen D geführt und gleichzeitig durch endlose Metallgewebebänder F an die Heizwalzen D angedrückt. Innerhalb der Metaligeweb:ebänder F sind zusätzlich Heizorgane G angebracht. Die Umlaufgeschwindigkeiten der Walzen-Band-Einrichtungen (D, F) sind. gegeneinander regelbar. Die einzelnen Bahnen werden sodann, nachdem sie auf die erforderliche Schweißtemperatur gebracht sind, durch die verstellbaren, hitzebeständigen und gummierten Gegenwalzen E auf die Heizwalzen D gepreßt, dabei verschweißt und anschließend auf die Wickeltrommel H aufgewickelt.With A are the foil tubes arranged in retractable carriages, the for replacement, can be hung in a side position B, denoted. From the roles A are the foils to be welded C over corresponding pulleys over the Heat rollers D out and at the same time by endless metal fabric belts F to the Heating rollers D pressed on. Inside the metal fabric belts F are additional heating elements G attached. The rotational speeds of the roller-belt devices (D, F) are. adjustable against each other. The individual tracks are then after they are on the required welding temperature are brought by the adjustable, heat-resistant and rubberized counter rollers E pressed onto the heating rollers D, thereby welded and then wound onto the winding drum H.
Zwischen: den einzelnen Gegenwalzen E ist eine Rollenbahn I angedeutet. Zwischen den Rollen .der Rollenbahn 1 sind ebenfalls, zusätzlich Heizorgane G angeordnet.Between: the individual counter rollers E, a roller conveyor I is indicated. Between the rollers .the roller conveyor 1, additional heating elements G are also arranged.
Sind die eingeihängten Folienrollen A fast leergefahren, so werden sie nach B umgehängt, damit die Vorrichtung kontinuierlich weiterlaufen kann. Bis, der Rest der Folie C aus :der Stellung B verbraucht ist, ist ein Wagen mit einer neuen FolienroileA eingefahren.If the attached film rolls A are almost empty, then put it around to B so that the device can continue to run. To, the rest of the slide C from: the position B is used up is a car with a run in new foil roll A.
