Description

Schweißelektrode zur Herstellung von flüssigkeitsgefüllten Ampullen aus Kunststoff Die Erfindung bezieht sich auf die Herstellung von flüssigkeitsgefüllten Ampullen aus Kunststoff und betrifft die Ausbildung der hierzu benötigten Schweißelektroden.Welding electrode for the production of liquid-filled ampoules made of plastic The invention relates to the manufacture of liquid-filled Ampoules made of plastic and relates to the formation of the welding electrodes required for this.

Kleine Ampullen aus Kunststoff haben weitgehende Verwendung gefunden, z. B. für die Aufbewahrung von Flüssigkeiten für Feuerzeuge. Das Problem ist dabei, die maschinell verschlossenen Ampullen öffnen zu können, ohne daß dabei ein Teil der Einfüllmenge verlorengeht. Small ampoules made of plastic have found widespread use, z. B. for the storage of liquids for lighters. The problem is to be able to open the mechanically sealed ampoules without losing any part the filling quantity is lost.

Dieses Problem ist insbesondere dann schwierig zu lösen, wenn während der Herstellung nach Füllung eines durchgehenden Kunststoffschlauches dieser zwischen besonders geformten Elektroden in die Ampullen einzeln aufgeteilt und an den Teilungsstellen durch Schweißung verschlossen wird. This problem is especially difficult to solve when during the production after filling a continuous plastic tube between these specially shaped electrodes divided into the ampoules individually and at the dividing points is closed by welding.

Durch die dabei auftretende Volumenverminderung erhöht sich in jeder der so erhaltenen Ampullen der Druck des eingeschlossenen Füllgutes, so daß dieses bei der Öffnung der prall gefüllten Ampullen her ausspritzt. Die derart herausspritzende Flüssigkeit kann unter Umständen große Schäden hervorrufen.The resulting decrease in volume increases in each of the ampoules obtained in this way, the pressure of the enclosed contents, so that this squirts out when the bulging ampoules are opened. The one that squirts out like that Liquid can cause major damage under certain circumstances.

Es ist nun bekannt, die Schweißelektroden für die Herstellung derartiger Ampullen in der Weise auszubilden, daß sie einen Entleerungskanal in der Schließnaht aussparen. Die Elektroden weisen zu diesem Zweck an der Kanalstelle eine entsprechende Ausnehmung bzw. Vertiefung auf. Es wird daher an dieser Stelle nicht gepreßt. Auf diese Weise lassen sich aber nur größere Kanalquerschnitte erzielen, mit welchen obengenannte Mängel insbesondere beim Verpacken von flüssigen Füllgütern nicht abgestellt werden konnten. It is now known, the welding electrodes for the production of such Form ampoules in such a way that they have an emptying channel in the closing seam leave out. For this purpose, the electrodes have a corresponding one at the channel point Recess or depression. It will therefore not at this point pressed. In this way, however, only larger duct cross-sections can be achieved, with which the above-mentioned deficiencies, especially when packing liquid products could not be turned off.

Der Erfindung liegt die Aufgabe zugrunde, derartige Schweißelektroden so auszubilden, daß die Auslaßkanäle an den Kunststoffampullen einen Ouerschnitt erhalten, der ein Austreten des unter Druck stehenden Füllgutes beim ersten Öffnen der Ampulle verhindert bzw. der erst bei Anwendung eines zusätzlichen äußeren Druckes ein Entleeren zuläßt. The invention is based on the object of such welding electrodes to be designed so that the outlet channels on the plastic ampoules have a cross section received, the leakage of the pressurized product when opening the first time the ampoule prevents or only when an additional external pressure is applied allows emptying.

Zur Lösung dieser Aufgabe ist die Schweißelektrode zur Herstellung von flüssigkeitsgefüllten Ampullen, die mit einem als Kapillare ausgebildeten Entleerungskanal versehen sind, aus einem mit dem Füllgut gefüllten Kunststoffschlauch, die eine der Entleerungskanalbreite entsprechende Aussparung aufweist, erfindungsgemäß dadurch gekennzeichnet, daß der in der Elektrode ausgesparte Raum plan mit der Elektrodenfläche durch einen Einsatz aus Isoliermaterial ausgefüllt ist, der das gleiche Verhalten gegen Druck- und Temperatureinwirkung wie das umgebende Elektrodenmaterial aufweist. To solve this problem, the welding electrode is for manufacture of liquid-filled ampoules with an emptying channel designed as a capillary are provided, from a filled with the filling plastic tube, the one the emptying channel width corresponding recess, according to the invention characterized in that the space recessed in the electrode is planar with the electrode surface is filled with an insert made of insulating material, which has the same behavior against the effects of pressure and temperature like the surrounding electrode material.

Dadurch wird es möglich, über den ganzen Nahtbereich eine gleichmäßige Pressung zu erzielen. This makes it possible to achieve a uniform finish over the entire seam area To achieve compression.

Der Querschnitt der Kapillare der Ampulle muß in Abhängigkeit vom Fülldruck gewählt werden. The cross section of the capillary of the ampoule must depend on the Filling pressure can be selected.

Bei geringem Fülldruck sind also größere Querschnitte zulässig. Infolgedessen muß aber auch der Einsatz aus Isoliermaterial den jeweiligen Erfordernissen angepaßt werden und hierzu wieder der in der Schweißelektrode ausgesparte Raum.Larger cross-sections are therefore permissible if the filling pressure is low. Consequently however, the use of insulating material must also be adapted to the respective requirements and for this purpose again the space recessed in the welding electrode.

Eine erfindungsgemäße Schweißelektrode kann daher noch dadurch gekennzeichnet sein, daß zur Bildung eines Entleerungskanals mit Kapillarwirkung die Breite der Aussparung bei einem Fülldruck von 0,4 atü im gefüllten Schlauch I,8 mm beträgt. A welding electrode according to the invention can therefore also be characterized be that to form a drainage channel with capillary action, the width of the Recess at a filling pressure of 0.4 atmospheres in the filled hose is 1.8 mm.

An Hand der Zeichnung sei die Erfindung näher erläutert. The invention will be explained in more detail with reference to the drawing.

Fig. I zeigt eine Draufsicht auf eine der beiden Elektroden aus Messing, B, mit einer Isolierung A, welche dem Anschlußstück des zu verschweißenden Schlauchverschlusses mit der Offnungskapillare C entspricht. Fig. I shows a plan view of one of the two electrodes made of brass, B, with insulation A, which is attached to the connector of the hose closure to be welded with the opening capillary C.

Fig. 2 zeigt eine fertige, gefüllte und verschweißte Ampulle aus elastischem Kunststoff in Ansicht, wobei der Kunststoff durchsichtig gestaltet ist. Fig. 2 shows a finished, filled and welded ampoule elastic plastic in view, the plastic being designed to be transparent.

Für die Schweißelektrode wird von einem Planschliff derselben ausgegangen. Die Elektrode als solche besteht einmal darin, daß ein nicht leitender Teil eingesetzt ist, welcher dem Kapillaranschluß entspricht, wie es in Fig. I bei A gezeigt ist. Bei B sieht man in der gezeichneten Draufsicht der Elektrode in natürlicher Größe den aus Messing bestehenden Teil. For the welding electrode, it is assumed that it is flat. The electrode as such consists in the fact that a non-conductive part is used which corresponds to the capillary connection, as shown at A in FIG. At B you can see the electrode in natural size in the drawn plan view the part made of brass.

Wesentlich ist weiter, daß das Isoliermaterial bei A in der Härte dem des Teiles B (Messing) genau entspricht, so daß nicht durch Abnutzung der Vorrichtung sowie unter Einwirkung von Hitze und Druck Vertiefungen entstehen können, welche die Herstellung von Kapillaren ausschließen. Das Material bei A muß bei einer Temperatur von 1000 C einen Druck von 400 kg/cm2 aushalten, wozu entsprechende Kunststoffmaterialien zur Verfügung stehen. It is also essential that the insulation material has A hardness that of part B (brass) corresponds exactly, so that not due to wear of the device as well as under the action of heat and pressure, depressions can arise, which exclude the manufacture of capillaries. The material at A must be at a temperature withstand a pressure of 400 kg / cm2 from 1000 C, including appropriate plastic materials be available.

Weiter wird als zweite Elektrode eine Elektrode benutzt, bei welcher der Teil A fehlt, die also als Voll-Elektrode aus Vollmessing ausgebildet ist. Furthermore, an electrode is used as the second electrode in which part A is missing, which is therefore designed as a full electrode made of full brass.

Beide Elektroden werden luft- oder wassergekühlt verwendet.Both electrodes are used air or water cooled.

Die Breite der Kapillare wird auf etwa I,8 mm für den Fall vorgesehen, daß der Fülldruck des Schlaucheso,4atü beträgt. Bei geringerem Überdruck kann die Kapillare breiter werden, der Teil A also in seinem röhrenförmigen Ansatz C auch breiter sein, bei höherem innerem tberdruck sind diese Maße geringer. The width of the capillary is provided at about 1.8 mm for the case that the filling pressure of the hose is 4atü. If the overpressure is lower, the Capillaries become wider, so does part A in its tubular extension C. be wider, with higher internal overpressure these dimensions are smaller.
