Abstract

A flange (2) for a fuel filter of a thermoplastic material resistant to the fuel, to be welded to the lower edge (4) of the filter element (3), has soot or mineral color particles (6) on the bonding side (5). The particles give an absorption coefficient of at least 0.7 for UV or IR light during welding.

Description

Die Erfindung betrifft einen aus kraftstoffbeständigem und thermoplastischem Kunststoff gefertigten Flansch, welcher an einer Verbindungsseite zur Verschmelzung mit einem Rand eines Filterelementes für einen Kraftstofffilter eines Kraftfahrzeuges vorgesehen ist. Weiterhin betrifft die Erfindung einen Kraftstofffilter mit zumindest einem aus thermoplastischem Kunststoff gefertigten Flansch und mit einem mit dem Flansch verbundenen Filterelement, wobei ein Rand des Filterelementes von dem Flansch umschmolzen ist.The The invention relates to a fuel-resistant and thermoplastic Plastic manufactured flange, which at a connection side to the Merging with an edge of a filter element for a Fuel filter is provided a motor vehicle. Farther The invention relates to a fuel filter with at least one made of thermoplastic resin flange and with a with the flange connected filter element, wherein an edge of the filter element is melted from the flange.

Aus thermoplastischem Kunststoff gefertigte Flansche für solche Kraftstofffilter werden bei heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Häufig weisen die Kraftstofffilter zwei Flansche auf, zwischen denen das Filterelement als ringförmig gefaltetes Filtergewebe angeordnet ist. Die an die Flansche angrenzenden Ränder des Filterelementes sind in den Flanschen umschmolzen. Diese Umschmelzung dichtet das Filterelement gegenüber dem Flansch ab und erzeugt eine vorgesehene Stabilität des Kraftstofffilters. Bei der Herstellung wird die mit dem Filterelement zu umschmelzende Verbindungsseite mit ultraviolettem oder infrarotem Licht bestrahlt und dabei die Fläche angeschmolzen. Anschließend wird das Filterelement auf die angeschmolzene Verbindungsseite gedrückt. Nach dem Erkalten des Flansches ist der Rand des Filterelementes mit dem Kunststoff umschmolzen. Entscheidend für die Qualität der Verbindung des Flansches mit dem Filterelement ist die bei der Bestrahlung erzeugte Schmelztiefe. Die Fertigungskosten steigen dabei mit der Bestrahlungsintensität und der Bestrahlungsdauer stark an.Out made of thermoplastic plastic flanges for such Fuel filters are commonly used in today's motor vehicles and are known from practice. Often, the fuel filters have two Flanges on, between which the filter element as an annular folded Filter fabric is arranged. The edges of the flange adjoining the flanges Filter element are melted in the flanges. This remelt seals the filter element opposite the flange and creates a planned stability of the fuel filter. During manufacture, the material to be remelted with the filter element becomes Connecting side irradiated with ultraviolet or infrared light while the surface melted. Subsequently the filter element is pressed onto the fused connection side. To the cooling of the flange is the edge of the filter element with melted over the plastic. Decisive for the quality of the connection of the flange with the filter element is that during irradiation generated melting depth. The manufacturing costs increase with the radiation intensity and the duration of irradiation.

Der Erfindung liegt das Problem zugrunde, einen Flansch der eingangs genannten Art so weiterzubilden, dass er eine besonders kostengünstige Fertigung des Kraftstofffilters ermöglicht. Weiterhin soll ein besonders kostengünstiger Kraftstofffilter geschaffen werden.Of the Invention is based on the problem, a flange of the above so-called type so that it is a particularly cost-effective production of the fuel filter allows. Furthermore, a particularly cost-effective fuel filter is created become.

Das erstgenannte Problem wird erfindungsgemäß dadurch gelöst, dass die Verbindungsseite Farbpartikel aufweist und dass die die Farbpartikel aufweisende Verbindungsseite einen Absorptionskoeffizienten für bei der Anschmelzung zur Verbindung mit dem Filterelement eingesetztes UV- oder IR-Licht von zumindest 0,7 aufweist.The The first problem is inventively achieved in that the connecting side has color particles and that the color particles having Connection side an absorption coefficient for at Melting used for connection to the filter element used UV or IR light of at least 0.7.

Durch diese Gestaltung werden die bei der Bestrahlung eingesetzten UV- oder IR Strahlen besonders stark absorbiert und damit in Wärme umgewandelt. Diese besonders starke Absorption des Materials des Flansches stellt eine ebenso hohe Umsetzung der eingesetzten Bestrahlungsenergie in Wärme sicher. Dies führt zu einer besonders hohen Schmelztiefe. Versuche haben gezeigt, dass sich hierdurch die Aufschmelzzeit des Flansches um bis zu 30% bei gleichbleibender Strahlungsintensität verkürzen lässt. Durch die Verkürzung der Aufschmelzzeit bei gleichzeitiger Strahlungsintensität lässt sich ein den erfindungsgemäßen Flansch aufweisender Kraftstofffilter besonders kostengünstig fertigen. Die mechanischen und chemischen Eigenschaften des thermoplastischen Kunststoffs werden bei einer entsprechenden Begrenzung der Beimischung der Farbpartikel beibehalten.By this design will be the UV radiation used in the irradiation or IR rays particularly strongly absorbed and thus converted into heat. This particularly strong absorption of the material of the flange provides an equally high implementation of the irradiation energy used in heat for sure. this leads to to a particularly high melting depth. Experiments have shown that As a result, the melting time of the flange by up to 30% to reduce the constant radiation intensity. By shortening the Melting time with simultaneous radiation intensity can be the flange of the invention exhibiting fuel filter particularly inexpensive manufacture. The mechanical and chemical properties of the thermoplastic with a corresponding limitation of the admixture of the color particles maintained.

Der erfindungsgemäße Flansch könnte beispielsweise ausschließlich auf der Verbindungsseite mit Farbpartikeln versehen sein. Eine besonders gleichmäßige Anschmelzung der Verbindungsseite lässt sich jedoch gemäß einer anderen vorteilhaften Weiterbildung der Erfindung sicherstellen, wenn der Kunststoff mit den Farbpartikeln durchmischt ist. Weiterhin gestaltet sich hierdurch die Fertigung des erfindungsgemäßen Flansches mit dem mit den Farbpartikeln durchmischten Kunst stoff in einem Arbeitsgang im Spritzgussverfahren besonders kostengünstig herstellen.Of the flange according to the invention could for example exclusively be provided on the connection side with color particles.

Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt inThe Invention leaves numerous embodiments to. To further clarify its basic principle is one of them shown in the drawing and will be described below. These shows in

1 einen Kraftstofffilter mit zwei erfindungsgemäßen Flanschen, 1 a fuel filter with two flanges according to the invention,

2 einen der erfindungsgemäßen Flansche aus 1 vor der Fertigung des Kraftstofffilters, 2 one of the flanges of the invention 1 before the manufacture of the fuel filter,

3 einen Teilschnitt durch den Kraftstofffilter im Bereich eines der Flansche. 3 a partial section through the fuel filter in the region of one of the flanges.

1 zeigt einen Kraftstofffilter 1 mit zwei Flanschen 2 und einem zwischen den Flanschen 2 angeordneten Filterelement 3. Das Filterelement 3 besteht aus ringförmig gefaltetem Filtergewebe und ist mit seinen an den Flanschen 2 angrenzenden Rändern 4 mit den Flanschen 2 verbunden. Die Flansche 2 sind aus dem thermoplastischem und kraftstoffbeständigem Kunststoff Polyacetatharz gefertigt. Die Verbindung der Flansche 2 mit dem Filterelement 3 ist durch Umschmelzung der Ränder 4 des Filterelementes 3 erzeugt. 1 shows a fuel filter 1 with two flanges 2 and one between the flanges 2 arranged filter element 3 , The filter element 3 consists of annular folded filter fabric and is with its on the flanges 2 adjacent edges 4 with the flanges 2 connected. The flanges 2 are made of thermoplastic and fuel-resistant plastic polyacetate resin. The connection of the flanges 2 with the filter element 3 is by remelting the edges 4 of the filter element 3 generated.

2 zeigt einen der Flansche 2 in einer perspektivischen Darstellung vor der Fertigung des in 1 dargestellten Kraftstofffilters 1. Der Flansch 2 weist eine ringförmige Verbindungsseite 5 zur Verbindung mit dem Filterelement 3 auf. Schematisch sind auf der Verbindungsseite 5 Farbpartikel 6 dargestellt. Bei der Fertigung des in 1 dargestellten Kraftstofffilters 1 wird die Verbindungsseite 5 mit ultraviolettem oder infrarotem Licht bestrahlt. Die Bestrahlungsener gie wird von der Oberfläche der Verbindungsseite 5 in Wärme umgewandelt. Die Farbpartikel 6 verhindern, dass das Licht den Flansch 2 durchdringt oder von der Verbindungsseite 5 reflektiert wird. Die Wärme führt zu einem Aufschmelzen des Kunststoffs der Verbindungsseite 5. Anschließend wird einer der Ränder 4 des Filterelementes 3 in die aufgeschmolzene Verbindungsseite 5 gedrückt. Das Erkalten des Kunststoffs verfestigt diesen und erzeugt eine dichte und stabile Verbindung des Flansches 2 mit dem Filterelement 3. 2 shows one of the flanges 2 in a perspective view before the production of in 1 shown fuel filter 1 , The flange 2 has an annular connection side 5 for connection to the filter element 3 on. Schematically are on the connection side 5 color particles 6 shown. In the production of in 1 shown fuel filter 1 becomes the connection side 5 irradiated with ultraviolet or infrared light. The irradiation energy is from the surface of the connection side 5 converted into heat. The color particles 6 prevent the light from the flange 2 penetrates or from the connection side 5 is reflected. The heat leads to a melting of the plastic of the connection side 5 , Subsequently, one of the edges 4 of the filter element 3 into the melted connection side 5 pressed. The cooling of the plastic solidifies it and creates a tight and stable connection of the flange 2 with the filter element 3 ,
