Description
Vorrichtung zum Herstellen von Handschuhen aus thermoplastischem Kunststoff Die Erfindung bezieht sich auf eine Vorrichtung zum fortlaufenden Herstellen von Handschuhen aus thermoplastischem Kunststoff durch Verschweißen von zwei Kunststoff-Folien. Device for making thermoplastic gloves Plastic The invention relates to an apparatus for continuous production of gloves made of thermoplastic material by welding two plastic foils.
Die Erfindung besteht dabei darin, daß eine elektrisch beheizte Schweißbacke vorgesehen ist, die Kanten entsprechend der jeweiligen Handschuh-Form und Größe auf weist, wobei nahe diesen Kanten ein hitzebeständiges, elektrostatisch aufladbares Folienband angeordnet ist, das entlang der Schweißbacke bewegbar ist, während gegenüberliegend ein endloses Band aus einer gleichen Folie in gleicher Richtung geführt ist und an dem endlosen Band eine Kunststoffbürste, die das Band elektrisch aufladet, so daß es die zu verschweißenden Folien festhält.The invention consists in that an electrically heated welding jaw is provided, the edges according to the respective glove shape and size has, with a heat-resistant, electrostatically chargeable near these edges Foil tape is arranged, which is movable along the welding jaw while opposite an endless belt made of the same film is guided in the same direction and a plastic brush on the endless belt that charges the belt electrically, see above that it holds the foils to be welded.
In manchen Fällen wird es vorteilhaft sein, das nahe der Schweißbacke vorgesehene Folienband ebenfalls als endloses Band auszubilden.In some cases it will be beneficial to have it close to the welding jaw the intended film strip is also to be designed as an endless belt.
Man kann nach einem weiteren Vorschlag der Erfindung auch so vorgehen, daß man an der Schweißbacke, mit geringem Abstand, zwei Folienbänder parallel zueinander vorbeiführ; dadurch hat man dann die Möglichkeit, zwischen diesen beiden Folien noch weitere zwei Kunststoff-Folien zur Herstellung von Handschuhen mitzuführen und auf diese Art jeweils gleie zWei Stücke in einem Arbeitsgang herzustellen. In einem solchen Fall werden zwar die Abwickelvorrichtungen etwas aufwendiger, doch wird sich auch dieser Aufwand stets dann, wenn große Stückzahlen laufend hergestellt werden, als vorteilhaft erweisen.According to a further proposal of the invention, one can also proceed as follows: that one on the welding jaw, with a small distance, two foil strips parallel to each other pass by; this then gives you the option to choose between these two foils carry two more plastic foils with you for the production of gloves and in this way you can produce two pieces in one operation. In In such a case, the unwinding devices are a bit more complex, but This effort is always increased when large quantities are continuously produced will prove beneficial.
Die Erfindung hat sich die Aufgabe gestellt, eine Vorrichtung zu schaffen, bei welcher die Kunststoff-Folien, aus denen die Handschuhe hergestellt werden, nicht direkt mit der Schweißbacke in Berührung kommen, um das häufige Kleben bleiben der verschweißten Handschuhe und auch das Klebenbleiben von Abfall zu vermeiden. Natürlich sollte nach Möglichkeit auch auf eine Gegenbacke verzichtet werden können.The invention has set itself the task of creating a device in which the plastic films from which the gloves are made, do not come into direct contact with the welding jaw to prevent frequent sticking the welded gloves and the sticking of waste. Of course, it should also be possible to dispense with a counter jaw if possible.
Die Lösung dieser Aufgabe hat die Erfindung nun dadurchgetroffen, daß zwischen der Elektrode und den Folien, aus denen die Handschuhe hergestellt werden, eine hitzebeständige Folie mitläuft, während eine zweite gleichartige Folie mit einem festen endlosen Transportband verbunden ist, so daß die Oberfläche dieses mit der Folie überzogenen Transportbandes als Gegenbacke dienen kann.The invention has now achieved this object by: that between the electrode and the foils from which the gloves are made a heat-resistant film is running, while a second film of the same type is connected to a fixed endless conveyor belt, so that the surface of this with the film-covered conveyor belt can serve as a counter jaw.
Weitere Meikriale der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels in Verbindung mit der Zeichnung und den Ansprüchen.Further meikrials of the invention emerge from the following description of an embodiment in connection with the drawing and the claims.
Eine elektrisch beheizbare Schweißbacke 1 ist mit Kanten 2 entsprechend den jeweils herzustellenden Handschuhformen bzw. Handschuhgrößen versehen. Nahe diesen Kanten 2 wird ein hitzebeständiges, elektrostatisch aufladbares Folienband 3 angeordnet, welches mit Hilfe von Walzen 4 in R>chtung der Pfeile Il'gefuhrt werden kann.An electrically heatable welding jaw 1 has edges 2 accordingly the respective glove shapes or glove sizes to be produced. Vicinity These edges 2 are a heat-resistant, electrostatically chargeable foil tape 3 arranged, which with the help of rollers 4 in the direction of the arrows II ' can be.
Unterhalb der Schweißbacke 1 ist ein endloses Band 9 vorgesehen, welches mit Hilfe von Trommeln 10 im Sinne der Zeile 12 in Bewegung gesetzt wird, so daß es also sich gleichlaufend mit dem Folienband 3 bewegt. Das endlose Band 9 ist mt einer hitzebeständigen, elektrostatisch aufladbaren Folie 5 belegt. An einer Stelle, bei dem skizzierten Beispiel links an der Bandumkehr, ist eine rotierende Kunststoffbürste 6 vorgesehen, die in ständiger Berührung mit der Folie 5 ist und diese elektrisch aufladet, so daß man die zu verschweißenden Folien 7, 8, die unter die Schweißbacke 1 zu bringen sind, durch einfaches Anhalten an das Band 5 festlegen und trasportieren kann.Below the welding jaw 1, an endless belt 9 is provided, which is set in motion with the help of drums 10 in the sense of line 12, so that So it moves concurrently with the film strip 3. The endless belt 9 is mt a heat-resistant, electrostatically chargeable film 5 covered. At one point in the example shown, on the left at the belt reversal, is a rotating plastic brush 6 is provided, which is in constant contact with the film 5 and this electrically charges, so that the foils to be welded 7, 8, which are under the welding jaw 1 are to be brought, set by simply stopping on the belt 5 and transport can.
Das Folienband 3 wird auf Walzen 4 in der angegebenen Pfeilrichtung aufgewickelt und man braucht dann bloß die Walzen 4 umlegen, wenn auf der rechten Seite das Folienband abgespult ist. Gegebenenfalls kann man aber auch dieses Folienband 3 als endloses Band verwenden.The film strip 3 is on rollers 4 in the direction of the arrow wound up and you only need to turn the rollers 4 if on the right Side the film tape is unwound. If necessary, however, this foil tape can also be used 3 use as an endless belt.
Wenn man zwei solcher Folienbänder 3 parallel zueinander an der SchweiBbacke 1 vorbeifüht, so ist es möglich, bei jedem Arbeitsgang zwei Handschuhe zu fer-'teigen, weil man zwischen den beiden Folienbändern noch jeweils zwei Kunststoff-Folien führen kann, aus denen die Handschuhe hergestellt werden.If you have two such film strips 3 parallel to each other on the welding jaw 1 passes by, so it is possible, two gloves for each work step to fer-'teigen, because there are still two plastic foils between the two foil strips from which the gloves are made.
Der Arbeitsvorgang geht nun so vor sich, daß man ein Folienband aus zwei Folien 7 und 8 von rechts, in Richtung des Pfeiles 12, an das Band 5 anlegt und wenn der Anfang dieser Folien 7, 8 unter die Schweißbacke gelangt, beginnt das Arbeitsspiel, indem die Folienbänder 3 und 5, 9 angehalten werden und die Schweißbacke 1 sich gegen das endlose Band 5, 9 bewegt. Nach Durchfuhren der Schweißung hebt sich die Schweißbacke 1 wieder ab, die beiden Bänder beginnen zu laufen und schieben die Folien 7, 8 um ein eolches Stück weiter, daß ein nächster Handschuh hergestellt werden kann.The process now goes on in such a way that a foil tape is off two foils 7 and 8 from the right, in the direction of arrow 12, to the tape 5 applies and when the beginning of these foils 7, 8 gets under the welding jaw, it begins Work cycle by stopping the foil strips 3 and 5, 9 and the sealing jaw 1 moves against the endless belt 5,9. After the welding has been carried out, it lifts the welding jaw 1 comes off again, the two belts start to run and slide the foils 7, 8 a little further that a next glove is produced can be.
Darauf halten die Bänder wieder an, die Schweißbacke senkt sich ab und stellt den nächsten Handschuh her.The belts then stop again and the welding jaw lowers and make the next glove.
Dieses Arbeitsspiel geht so lange weiter, als zu ves schweißende Folien 7, 8 zugeführt werden, wobei die Steuerung durch irgendwelche bekannten Lichtschranken od. dgl. erfolgen kann.This work cycle continues as long as foils to be welded 7, 8, the control by any known light barriers od. The like. Can take place.
