Description

Presse zum dielektrischen Warmbearbeiten und Verschweißen von Folien aus organischem, thermoplastischem Material Dile Erfindung bezieht sich auf Pressen zum dielektrischen Warmbearbeiten und Schweißen von Folien aus organischem, thermoplastischem Material, die mit einer Fingerschutzeinrichtung üblicher schaittechnischer Ausführung versehen sind.Press for dielectric hot working and welding of foils made of organic, thermoplastic material Dile invention relates to pressing for dielectric hot working and welding of foils made of organic, thermoplastic Material with a finger protection device of the usual mechanical design are provided.

Pressen, die Drücke über einige Kilogramm erzeugen und durch einen Servoantrieb betätigt werden, bedürfen besonderer Einrichtungen zum Schutze der Bedienungsperson. Zu diesem Zweck sind bei Stanzen, Querschneidern u. dgl. Einrichtungen bekannt, die eine Betätigung der Presse unmöglich machen, solange sich die Hände der Bedienungsperson nicht außerhalb des Gefahrenbereichs befinden. Derartige Einrichtungen lassen sich jedoch nur anwenden, wenn die Arbeitsstücke während des Schließens der Presse nicht mehr berührt zu werden brauchen. Dieser Fall aber ist bei der Beafbeitung von thermopLaistischen Kunststoffolien auf Schweißpressen od. dgl. nicht gegeben, da es hier meist notwend,ig ist, die Folienzuschnitte vor dem endgültigen Schließen der Presse mit den Händen zu halten oder in die richtige Lage zu bringen. Presses that generate pressures over a few kilograms and through one Servo drives are operated, require special facilities to protect the Operator. For this purpose, punching, cross-cutters and the like are equipped with devices known that make it impossible to operate the press as long as the hands are together of the operator are not outside the danger area. Such facilities can only be used, however, if the workpieces are being closed during the closing of the Press no longer need to be touched. But this case is in the process of processing of thermoplastic plastic foils on welding presses or the like not given, as it is usually necessary here to cut the foil before the final closing to hold the press with your hands or to bring it into the correct position.

Auch bei derartigen Pressen ist eine F,iingerschutzeinrichtung erforderlich. A finger protection device is also required in such presses.

Bei Pressen, die der Warmbearbeitung, insbesondere der Schweißung von Folien aus thermoplastischem Material dienen, ist es erwünscht, daß sie in offener Stellung eine möglichst große Durch- laßhöhe aufweisen, um eine leichte Einbringung der Schweißgüter zu gestatten. Dieser Durchlaß soll so groß sein, daß die Finger der Bedienungsperson ohne Schwierigkeiten unter den beweglichen Preßstempel und die daran meist befestigten Werkzeuge (Elektroden) greifen können. Für die eigentliche Ausrichtung der zugeschnittenen Folienteile in die endgültige Bearbeitungs lage ist demgegenüber eine Stellung des Preßstempels am vorteilhaftesten, bei welcher sich die Werkzeuge unmittelbar über den Folien befinden oder Ibereits schon mit ganz leichtem Druck auf diesen aufLiegen. Auf diese Weise wird vermieden, daß sich die Zuschnitte nach Fortnehmen der Finger noch verschieben. In the case of presses that are used for hot working, especially welding Served by films made of thermoplastic material, it is desirable that they be in the open Position the largest possible let height have to a to allow easy introduction of the weld metal. This passage should be so big be that the operator's fingers easily under the movable ones Press ram and the tools (electrodes) usually attached to it can grip. For the actual alignment of the cut foil parts in the final Machining position, on the other hand, a position of the ram is most advantageous, in which the tools are directly above the foils or already lie on them with very light pressure. In this way it is avoided that the blanks are still shifting after removing the fingers.

Unter Berücksichtigung dieser Gegebenheiten wird zum Schutze des Bedienungspersonals für eine derartige Presse erfindungsgemäß vorgeschlagen, bei der Steuervorrichtung zum Schließen der Presse zwei Schaltstufen vorzusehen, wobei während der ersten Schaltstufe die Schutzeinrichtung in Tätigkeit bleibt und am Ende derselben ein Schließen der Presse nur insoweit bewirkt wird, daß noch ein Einrichten des Werkstückes möglich ist, die Finger aber nicht mehr unter das Werkzeug gebracht werden können, dagegen in der zweiten, den eigentlichen Preß- oder Schweißvorgang umfassenden Schaltstufe dte Eingerschutzeinrichtung unwirksam bleibt. Taking these circumstances into account, the protection of the Operators for such a press proposed according to the invention at to provide two switching stages of the control device for closing the press, wherein the protective device remains in operation during the first switching stage and on At the end of the same a closing of the press is effected only to the extent that one more Setting up the workpiece is possible, but the fingers are no longer under the tool can be brought, however, in the second, the actual pressing or welding process comprehensive switching stage dte single protection device remains ineffective.

Naturgemäß ist der erste Schließungsabschnitt verhältnismäßig groß, der zweite verhältnismäßig klein. Bei einem praktischen Anwendungsheisp iel unterteilen der erste und der zweite Schließungsabschnitt den Gesamthub im Verhältnis 5 : I. Naturally, the first closing section is relatively large, the second relatively small. Subdivide in a practical application example the first and the second closing section the total stroke in the ratio 5: I.

Um eine Anpassung an die jeweiligen Arbeitsverhältnisse zu ermögl,ichen, ist es zweckmäßig, die absoluten Größen der beiden Schfießungsstufen oder ihr gegenseitiges Verhältnis bei konstantem Gesamthub veränderlich zu gestalten. In order to enable an adjustment to the respective employment conditions, it is appropriate to use the absolute magnitudes of the two stages of the shooting or their mutual Make the ratio variable with a constant total stroke.
