Abstract

Thermoplastic fabric and similar materials are bonded together by welding, using equipment with two jaws, one fixed and the other moving vertically, and a welding wire between them. Each jaw has a suitable covering in elastic material for gripping the fabrics. The equipment used can be mounted on a carriage to move from one fabric machine to another. One fixed jaw contains an air cylinder whose piston moves the other jaw to and from it. Each jaw has e.g. silicone rubber strips to grip the fabrics. Action is rapid, machine is simple, good bonds are obtd. and there is no damage to fabrics.

aus thermoplastischem Werkstoff Die Erfindung betrifft eine Vorrichtung zum Verbinden von Geweben od. dergl. aus thermoplastischem Werkstoff durch Schmelzschweißen. Derartige Vorrichtungen dienen zum Verbinden zweier Bahnen aus Roh gewebe oder maschenfestem Kunstgewebe, wobei die Verbindung schnell und sicher durch ein einfach gebautes Gerät hergestellt werden soll, welches trotz niedriger Kosten doch zuverläßig arbeitet.Made of thermoplastic material The invention relates to a device For joining fabrics or the like made of thermoplastic material by fusion welding. Such devices are used to connect two webs of raw fabric or mesh Artificial fabric, the connection being quick and secure through a simply built Device is to be produced, which works reliably despite low costs.

Die bekannten Vorrichtungen dieser Art sind verhältnismäßig platzraubend und teuer sowie relativ langsam im Betrieb. Die Betriebszeit eines einzigen Arbeitszyklus beträgt etwa 2 Minuten.The known devices of this type are relatively bulky and expensive and relatively slow to operate. The operating time of a single duty cycle is about 2 minutes.

Der Erfindung liegt die Aufgabe zugrunde, die vorbekannten Vorrichtungen zu vereinfachen und zu verbessern sowie gleichzeitig die Dauer eines Betriebszyklus zu verringern. Es werden Zeiten von etwa 10 Sekunden angestrebt. Wesentlich ist, daß trotz dieser verringerten Arbeitszeit eine Schädigung selbst empfindlicher oder schwer zu bearbeitender Gewebe nicht eintritt.The invention is based on the object of the previously known devices to simplify and improve as well as the duration of an operating cycle to reduce. Times of around 10 seconds are aimed for. What is essential is that despite this reduced working time, damage self sensitive or difficult to work tissue does not enter.

Diese Aufgabe wird durch eine Vorrichtung gelöst, die im wesentlichen aus zwei Backen besteht, von denen die eine fest angeordnet und die andere in senkrechter Richtung relativ zu dieser bewegbar ist und daß im Bereich zwischen den Backen ein elektrisch beheizter Schweißdraht vorhanden ist.This object is achieved by a device that essentially consists of two jaws, one of which is fixed and the other in a vertical position Direction is movable relative to this and that in the area between the jaws electrically heated welding wire is present.

Die Vorrichtung kann entweder als unabhäng#s, vorzugsweise auf einen Wagen gebautes Gerät ausgeführt werden, wobei das Gerät dann mit Hilfe des Wagens an eine beliebige Textilmaschine gefahren werden kann oder es kann auch in eine Textilmaschine integriert oder an diese angebaut werden.The device can either be independent, preferably on one Car-built device can be executed, with the device then with the help of the car can be driven to any textile machine or it can also be in a Textile machine integrated or attached to it.

Als nicht einschränkende Beispiele für derartige Textilmaschinen werden unter anderem Wickelmaschinen, Abroller, Prüf- und Aufwickelmaschinen genannt.As non-limiting examples of such textile machines are among other things called winding machines, dispensers, testing and rewinding machines.

Die Erfindung wird im folgenden anhand der beiliegenden Zeichnungnäher erläutert. Es stellen dar: Fig. 1 eine Seitenansicht einer auf einem Wagen angeordneten Vorrichtung; Fig. 2 die geschnittene Stirnansicht der in Fig. 1 dargestellten Vorrichtung, Fig. 3 eine perspektivische Darstellung einer Ausführungsform der Vorrichtung; Fig. 4 die Stirnansicht eines weiteren Ausführungsbeispiels der Vorrichtung, die an eine Textilmaschine angebaut ist; Fig. 5 die Seitenansicht der Vorrichtung gemäß Fig. 3.The invention is explained in more detail below with reference to the accompanying drawings explained. The figures show: FIG. 1 a side view of an arranged on a carriage Contraption; FIG. 2 shows the sectional end view of the one shown in FIG Contraption, 3 shows a perspective illustration of an embodiment of the device; Fig. 4 shows the end view of a further exemplary embodiment of the device, which is attached to a Textile machine is attached; FIG. 5 shows the side view of the device according to FIG. 3.

In den Figuren 1 und 2 ist zunächst ein Wagen 1 erkennbar, der vorzugsweise rechteckige Form hat und über Räder 2 zum leichten Transport der Vorrichtung von einer Textilmaschine zur anderen innerhalb eines Werkes vorgesehen ist. Die Vorrichtung liegt auf einer Platte 3 des Wagens 1 und besteht grurdsätzlich aus der festen Backe 4, in der ein Luftzylinder angeordnet ist, dessen Kolbenstange 5 die bewegbare Bacle6 hin- und herbewegt, wobei diese auf geeigneten Führungen mit Hilfe von Rädern 7 läuft. Die beiden Backen 4 und 6 sind mit leistenförmigen Überzügen aus Spezialgummi, beispielsweise Silikongummi, versehen, welche bewirken, daß die zu verbindenen Gewebe leicht ohne Beschädigung erfaßt werden können. Zwischen den Backen 4 und 6 liegt ein Schweißdraht 9, der mit Hilfe nicht gezeichneter Stromkreise elektrisch beheizt wird. Der Schweißdraht 9 ist an seinen Enden mit Gewichten 10 ausgerüstet, die ihn trotz der im Laufe des Betriebszyklus eintretenden Temperaturschwankungen stets im gespannten Zustand halten. Ein ebenfalls nicht gezeichneter Zeitgeber stellt die Heizzeit für den Schweißdraht unter Berücksichtigung der von der Art der zu verbindenden Gewebe abhängenden Wärmemenge ein.In Figures 1 and 2, a carriage 1 can first be seen, which is preferably rectangular in shape and has wheels 2 for easy transport of the device one textile machine to another is provided within a plant. The device lies on a plate 3 of the carriage 1 and basically consists of the fixed jaw 4, in which an air cylinder is arranged, the piston rod 5 of which has the movable bacle6 moved back and forth, these on suitable guides with the help of wheels 7 runs. The two jaws 4 and 6 are covered with strips of special rubber, for example silicone rubber, which cause the tissues to be joined can be easily grasped without damage. Between the jaws 4 and 6 lies a welding wire 9 which is electrically heated with the aid of circuits not shown will. The welding wire 9 is equipped at its ends with weights 10 that it despite the im Temperature fluctuations occurring during the operating cycle always keep it tensioned. A timer, also not shown, provides the heating time for the welding wire taking into account the type of to connecting tissue depending on the amount of heat.

Aus Fig. 3 ist ersichtlich, daß die bewegbare Backe 6 auch unmittelbar von den Kolbenstangen 20 der Luftzylinder 21 gesteuert werden kann, die seitlich am Wagen 1 befestigt sind.From Fig. 3 it can be seen that the movable jaw 6 also directly can be controlled by the piston rods 20 of the air cylinder 21, the laterally are attached to the carriage 1.

Ein Querträger 22 verbindet die beiden Wagen 1 miteinander, während ein Schutzblech 23 den Bedienungsmann vor einer eventuellen Berührung mit dem Schweißdraht schützt. Das Bedienungsblech besteht im dargestellten Beispiel aus zwei Platten, zwischen denen das Gewebe zur Schweißzone hin gefördert wird.A cross member 22 connects the two carriages 1 together while a guard 23 prevents the operator from contacting the welding wire protects. In the example shown, the control panel consists of two panels, between which the tissue is conveyed to the welding zone.

Der Arbeitsgang der Vorrichtung kann entweder von Hand oder durch einen Druckknopf oder auch automatisch gesteuert werden. Nach der Einführung der beiden zu verbindenden Gewebsenden läßt man den Arbeitsgang an. Die bewegbare Backe 6 wird gegen die feste Backe 4 gedrückt oder gezogen. Daraufhin wird der Schweißdraht 9 beheizt, so daß das zwischen den leistenförmigen Überzügen ergriffene Gewebe geschweißt wird.The operation of the device can either be done by hand or by controlled by a push button or automatically. After the introduction of the Both ends of the tissue to be connected are allowed to start the operation. The movable jaw 6 is pressed or pulled against the fixed jaw 4. Thereupon the welding wire 9 heated so that the tissue gripped between the strip-shaped coatings is welded will.

Gleichzeitig schneidet der Schweißdraht die beiden wegzuwerfenden Enden des Gewebes ab, welche beispielsweise in einen Ausschußsammelraum fallen.At the same time, the welding wire cuts the two to be thrown away Ends of the tissue from which, for example, fall into a waste collection space.

Nach Ablauf der sehr kurzen Schweißzeit (ca. 10 Sekunden) werden die Backen geöffnet, wobei der Schweißdraht ausgeschaltet und das verbundene Gewebe freigegeben wird, so daß die Arbeit ohne Unterbrechung der Textilmaschine weitergeführt werden kann.After the very short welding time (approx. 10 seconds) the Jaws open, with the welding wire turned off and the connected tissue is released so that the work can continue without interrupting the textile machine can be.

In den Figuren 4 und 5 wird ein etwas unterschiedliches Ausführungsbeispiel erläutert, welches unmittelbar an einer Textilmaschine angebracht ist. Maschinen dieses Ausführungsbeispieles können je nach Art der Textilmaschine in senkrechter, waagrechter oder schräger Lage angewandt werden.A somewhat different exemplary embodiment is shown in FIGS explains which is attached directly to a textile machine. machinery of this embodiment can, depending on the type of textile machine, in vertical, horizontal or inclined position can be used.

Gemäß diesem Ausführungsbeispiel sind die Luftzylinder 11 an einem mit der Textilmaschine verbundenen Gerüst 12 befestigt, wobei die Backen 14 mit Hilfe der Luftzylinder 11 hin- und herbewegt werden, mit denen sie über die Kolbenstangen 13 verbunden sind. Die Backen 14 und 16 sind mit leistenförmigen Überzügen 15 beziehungsweise 15A ausgerüstet, welche aus speziellen Werkstoffen, z.B. Silikongummi, bestehen. Der Schweißdraht 17 ist über Rollen umgelenkt und an seinen Enden mit Gegengewichten 18 verbunden, welche in Führungen 19 des Gerüstes 12 laufen.According to this embodiment, the air cylinders 11 are on one attached to the textile machine connected frame 12, the jaws 14 with Help the air cylinder 11 to be moved back and forth with which they over the piston rods 13 are connected. The jaws 14 and 16 are provided with strip-shaped coatings 15 and 15 respectively 15A, which are made of special materials, e.g. silicone rubber. The welding wire 17 is deflected over rollers and with counterweights at its ends 18 connected, which run in guides 19 of the frame 12.

Der Betrieb und der Antrieb dieses zweiten Ausführungsbeispiels sind gleichartig mit denjenigen, die früher beschrieben wurden und selbstverständlich kann der Vorrichtungsarbeitsgang völlig automatisch und gleichlaufend mit dem Textilmaschinenarbeitsgang sein.The operation and drive of this second embodiment are similar to those previously described and taken for granted the fixture operation can be fully automatic and concurrent with the textile machine operation be.

Selbstverständlich könnten verschiedene Abwandlungen, Veränderungen, Zugaben und Auswechslung von Teilen an dieser Vorrichtung durchgeführt werden, ohne daß der Schutzbereich der Ansprüche verlassen wird. So ist es beispielsweise möglich, die Vorrichtung, obwohl sie im Zusammenhang mit der Verbindung von Textilenbahnen beschrieben worden ist, auch zum Verbinden anderer Gegenstände aus thermoplastischen Kunststoffen anzuwenden, z.B. Platten aus Schaumstoff, Filme oder Folien und so weiter.Of course, various modifications, changes, Additions and replacements of parts on this device can be carried out without that the scope of protection of the claims is left. For example, it is possible the device, although it is related to the connection of textile webs has been described, also for joining other articles made of thermoplastic Plastics, e.g. sheets made of foam, films or foils and so on Further.
