Description

Vorrichtung zur Reinigung von profilierten Elektrodenrollen mit einem Schabemesser Die Erfindung betrifft eine Vorrichtung zur Reinigung und Formhaltung von profilierten Elektrodenrollen an Widerstands-Schweißmaschinen, insbesondere an Folien-Stumpfnahtschweißmaschinen, mit einem einteiligen oder mehrteiligen, dem Rollenprofil entsprechend profilierten Schabemesser, das kontinuierlich und nachgiebig an die Elektrodenrolle radial angedrückt wird.Device for cleaning profiled electrode rollers with one Scraper knife The invention relates to a device for cleaning and maintaining shape of profiled electrode rolls on resistance welding machines, in particular on foil butt seam welding machines, with a one-part or multi-part, the Roll profile appropriately profiled scraper knife that is continuous and resilient is pressed radially against the electrode roller.

Bei den bekannten Vorrichtungen sind die Schabemesser starr geführt und federn nur in radialer Richtung der Elektrodenrolle. Die günstigsten Verhältnisse werden bekanntlich dann erzielt, wenn Schabemesser einen ziehenden Schnitt ausführen können. Da die meisten Elektrodenrollen in beiden Drehrichtungen umlaufen während des Schweißens, kann bei den bekannten Schabemessern entweder nur in einer Richtung der Vorteil des ziehenden Schnittes wahrgenommen werden, oder man muß die Schabemesser mit einem Anstellwinkel von 90° betreiben.In the known devices, the scraper knives are rigidly guided and only spring in the radial direction of the electrode roller. The best conditions are known to be achieved when scraping knives make a pulling cut can. Since most electrode rollers rotate in both directions during welding, can only be done in one direction with the known scraping knives the advantage of the pulling cut can be perceived, or you have to use the scraping knife operate with an angle of attack of 90 °.

Die Erfindung bezweckt, diese Nachteile auszuschalten und einen ziehenden Schnitt der Schabemesser in beiden Drehrichtungen der Elektrodenrollen zu ermöglichen.The invention aims to eliminate these disadvantages and a pulling Allow the scraper knife to cut in both directions of rotation of the electrode rollers.

Die Erfindung besteht darin, daß das Schabemesser für das Arbeiten mit ziehendem Schnitt in beiden Rellendrehrichtungen schwenkbar gelagert ist.The invention is that the scraper knife for working is pivotably mounted with a pulling cut in both directions of rotation.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig.1 eine Seitenansicht der Reinigungsvorrichtung und Fig. 2 einen Schnitt in der Ebene II-II in Fig. 1. Die am _Maschinengestell 1 schwenkbar gelagerten und durch einen Antrieb gegenläufig gedrehten Elektrodenrollen 2, 3 einer Folien-Sumpfnahtschweißtnaschinewerden durch hydraulische Vorrichtungen 4 gegeneinandergedrückt. Die Elektrodenrollen 2, 3 haben am Umfang ein Profil s, das von einer mittleren axialen Fläche und zwei an diese seitlich anschließenden geneigten Flächen gebildet wird. Die auf Vorratsrollen aufgewickelten Folienbänder 6 werden über Führungen 7 der Schweißstelle zugeführt.An exemplary embodiment of the invention is shown in the drawing. 1 shows a side view of the cleaning device and FIG. 2 shows a section in the plane II-II in Fig. 1. The swivel-mounted on the _Maschine frame 1 and Electrode rollers 2, 3 of a foil sump seam welding machine rotated in opposite directions by a drive pressed against each other by hydraulic devices 4. The electrode rollers 2, 3 have on the circumference a profile s that of a central axial surface and two is formed on these laterally adjoining inclined surfaces. The ones on supply rolls The wound film strips 6 are fed to the welding point via guides 7.

Jeder- Halter 19 des einteiligen Schabemessers 9 ist in Arbeitsrichtung vor den Elektrodenrollen 2, 3 angeordnet. Er besteht aus einem Arm, der mit seinem einen Ende in einem gekrümmten Schlitz 20 eines mit der Elektrodenrollenlagerung verbundenen Segments 21 dreh-, verschieb- und feststellbar ist und der an seinem anderen Ende eine Hülse 22 trägt, in der das Schabemesser 9, mittels Schrauben 23 parallel zur Elektrodenrollenachse einstellbar, schwenkbar gelagert ist. Die Hülse 22 wird durch eine in der Folienführung 7 drehbare Rändelschraube 24, in der ein Bolzen 25 unter Federspannung verschiebbar ist, auf die Elektrodenrolle 2 bzw. 3 hin geschoben und damit das Schabemesser 9 an das Profil der Rolle 2 angedrückt. Bei Umkehr der Bewegungsrichtung der Maschine legt sich das Schabemesser 9 selbsttätig in die entsprechende Stellung um.Each holder 19 of the one-piece scraping knife 9 is in the working direction arranged in front of the electrode rollers 2, 3. It consists of an arm that connects to his one end in a curved slot 20 one with the electrode roller bearing connected segment 21 is rotatable, displaceable and lockable and at his the other end carries a sleeve 22 in which the scraper 9, by means of screws 23 adjustable parallel to the electrode roller axis, is pivotably mounted. The sleeve 22 is by a in the film guide 7 rotatable knurled screw 24 in which a Bolt 25 is displaceable under spring tension on the electrode roller 2 or 3 pushed towards and thus the scraping knife 9 pressed against the profile of the roller 2. When the direction of movement of the machine is reversed, the scraping knife 9 automatically lies down to the appropriate position.

Das radial nachgiebig an das Profil 5 der betreffenden Elektrodenrolle 2 bzw. 3 angedrückte Schabemesser 9 reinigt, da sein Profil dem Profil der Rolle entspricht, laufend das Rollenprofil von angesetzten Schweißspritzern und Oxydbildungen, so daß die Festmaße des Elektrodenrollenprofils 5 erhalten bleiben und ein gleichmäßiges Andrücken der Schweißfolie 6 an die Stumpfnaht gesichert ist. Hierdurch wird eine hohe Güte der Schweißnaht gewährleistet.The radially flexible to the profile 5 of the electrode roller in question 2 or 3 pressed scraper knife 9 cleans, since its profile corresponds to the profile of the role the roll profile of weld spatter and oxide formation, so that the fixed dimensions of the electrode roller profile 5 are retained and a uniform one Pressing the welding foil 6 is secured against the butt seam. This creates a high quality of the weld seam guaranteed.
