Die Erfindung betrifft eine Vorrichtung zum Herstellen von Siegelnähten an Verpackungshüllen, mit der Zuschnitte aus heißsiegelfähigen Packstoffen um die zu verpackenden Gegenstände ar der zunächst us Formdorne herumgelegt, die Ränder die wer zuschnitte dann unter Verwendung eines Leitelements gegen einander gelegt und schliesslich mit Hilfe von Siegelbacken miteinander verschweißt werden.The invention relates to a device for producing sealed seams on packaging sleeves with which blanks made of heat-sealable packaging materials around the Objects to be packaged are initially laid around the us mold mandrels, the edges who then placed the blanks against each other using a guide element and finally welded together with the help of sealing jaws.

Durch die US-Patentschriften 2 966 632 und 3 140 643 ist es be-@eits bekannt, Leitschienen zu verwenden. gegen die sich die Ränder vom um Formdorne gelegten zuschnitten anlegen derart dass die Ränder zu sogenannten Finseal-Nähten gegeneinandergesiegelt werden könnsnl Es wurde auch schon vorgeschlagen, statt der Leitschienen einen Druckluftstrom zu verwendens Bei sehr dtlnnen, weichen oder zum Rollen neigenden Packstoffen entfernen sich jedoch die Enden der Zuschnitte in unkontrollierbarer Weise von den Leitmitteln, so dass beim Siegelvorgang fehlerhafte Nähte entstehen Die Erfindung hat sich die Aufgabe gestellt, derartige Nachteile dadurch zu vermeiden, dass gemäss dem Heuptmerkmal der Erfindung jede Arbeitsfläche der Siegelbacken mit Öffnungen für Saugluft versehen und die Saugluft derart gesteuert ist, dass die gegeneinander zu spiegelnden Ränder der Zu schnitte an diesen Arbeitsv flächen der Siegelbacken bis zum Beginn des eigentlichen Sie gelvorganges angesaugt gehalten sind.It is already known from US Patents 2,966,632 and 3,140,643 known to use guardrails. against which the edges of the mandrels laid around Make cuts in such a way that the edges are sealed together to form so-called finseal seams will Könnsnl It has also been proposed to use a compressed air stream instead of the guide rails To be used Remove packaging materials that are very thin, soft or tend to roll However, the ends of the blanks are in an uncontrollable manner from the guide means, so that faulty seams arise during the sealing process The task set to avoid such disadvantages in that, according to the main feature According to the invention, each working surface of the sealing jaws is provided with openings for suction air and the suction air is controlled in such a way that the edges to be mirrored against each other the cuts on these working surfaces of the sealing jaws up to the start of the actual They are kept sucked in gel process.

Ein weiteres Merkmal der Erfindung kennzeichnet sich durch bewegliche mit den Siegelbacken wenigstens zeitweise zusaminenarbeitende Führungselemente für die innere Abstützung der miteinander zu versiegelnden Teile der Zuschnittränder.Another feature of the invention is characterized by being movable with the sealing jaws at least temporarily cooperating guide elements for the inner support of the parts of the cutting edges to be sealed together.

Diese Stütz- oder Führungselemente sind bei einer bevorzugten Asuführungsform der Erfindung als spreizbares Platten oder Fingerpaar ausgebildet, das derart gehalten und geführt ist, dass es zwischen die Zuschnittränder einführbar und synchron mit der Schließbewegung der Siegelbacken bei gleichzeitiger Verminderung der Spreizung wieder aus dem n Bereich der Siegelbacken herausführbar ist.These support or guide elements are in a preferred embodiment of the invention designed as expandable plates or pair of fingers that are held in such a way and it is guided that it can be inserted between the cutting edges and synchronously with the closing movement of the sealing jaws while at the same time reducing the spread can be removed again from the n area of the sealing jaws.

Mit einer derartigen erfindungsgemässen Vorrichtung wird uoa. der Vorteil erreicht, dass sich auch bei sehr weichen Packstoffen die Ränder der Zuschnitte ohne Störung über den Gegenständen gegeneinanderführen und zu abstehenden Siegelnähten verschweissen lassen.With such a device according to the invention uoa. the The advantage achieved is that the edges of the blanks are even with very soft packaging materials without disturbance over the objects against each other and lead to protruding sealing seams let weld.

Ein bevorzugtes Ausf«hrungsbeispiel der Erfindung wird nachstehend anhand von schematischen Zeichnungen näher erläutert: In den Zeichnungen zeigt: Fig. 1 die wesentlichen Teile der erfindungsgemässen Vorrichtung, und Fig. 2 bis 4 die Vorrichtung gemäss Figq 1 in weiteren Arbeits-Stellungen.A preferred embodiment of the invention is shown below Explained in more detail with reference to schematic drawings: In the drawings shows: 1 shows the essential parts of the device according to the invention, and FIGS. 2 to 4 the device according to Figq 1 in further working positions.

Die dargestellte Vorrichtung des Asuführungsbeispiels der Erfindung besteht im wesentlichen aus Paaren einerseits von an verschwenkbaren Hebeln 1, 2 befestigten Siegelbacken 3. 4, ferner von Platten 5, 6 sowie Blasdüsen 7.The illustrated device of the embodiment of the invention consists essentially of pairs on the one hand of pivotable levers 1, 2 attached sealing jaws 3, 4, furthermore plates 5, 6 and blow nozzles 7.

Die Siegelbacken 3, 4 weisen in ihren Arbeitsflächen 8, 9 Saugt dffnungen 10 auf, die in einen Sammelkanal 11 münden, der in an sich bekannter Weise über ein nicht gezeichnetes Steuerventil mit einer nicht gezeichneten Vorrichtung zum Erzeugen von Unterdruck verbunden ist. Die Hebel 1,2 kennen beispielsweise mittels eines an sich bekannten, nicht dargestellten Xurvengetriebes in Bewegung versetzt werden.The sealing jaws 3, 4 have suction openings in their work surfaces 8, 9 10, which open into a collecting channel 11, which in a manner known per se a control valve (not shown) with a device (not shown) for Generating negative pressure connected is. The levers 1,2 know for example by means of a known Xurvengetriebes, not shown, in motion be moved.

Die Platten, 6 sind an Hebeln 12, 13 befestigt, die auf einer gemeinsamen Achse 14 verschwenkbar gelagert sind, die ihrerseite von verschwenkbar angeordneten Hebeln 15 getragen wird.The plates, 6 are attached to levers 12, 13, which on a common Axis 14 are pivotably mounted, the pivoted on their side of Lever 15 is worn.

Die Hebel 15, von denen nur einer auf den Zeichnung sichtbar ist, können, ebenfalls mittels bekannter Kurvengetriebe gesteuert, um eine Achse 16 verschwenkt werden0 Die Hebel 12, 13 weisen Arme 17, 18 auf, die an ihren Enden mit drehbar gelagerten Kurvenrollen 19 versehen sind. Eine Zugfeder 20 ist an den Enden der Arme 17, 18 derart angeordnet, dass letztere gegeneinander gezogen und dabei die Kurvenrollen 19 gegen eine ortsfest angeordnete Leitkurve 21 gedrückt werden. wodurch der Abstand der Platten 5,6 gesteuert wird.The levers 15, only one of which is visible on the drawing, can be pivoted about an axis 16, also controlled by means of known cam gears werden0 The levers 12, 13 have arms 17, 18 which can be rotated at their ends mounted cam rollers 19 are provided. A tension spring 20 is at the ends of the Arms 17, 18 arranged such that the latter are drawn against each other and thereby the Cam rollers 19 are pressed against a stationary cam 21. through which the distance between the plates 5,6 is controlled.

Ein in einen Förderbecher 22 eingelegter Zuschnitt 23, in den eine vorbestimmte Menge länglicher Gegenstände 24, z. B.A blank 23 placed in a conveyor cup 22, into which one predetermined amount of elongated objects 24, e.g. B.

Makkaroni eingegeben worden ist, wird in an sich bekannter Weise unter die Siegelbacken 3,4 und die Platten 5,6 gefordert. Ober die Ränder des Förderbechers 22 Mngende Teile des Zuschnitts 23 werden mit Hilfe der Blasdüsen 7 im wesentiichen senkrecht nach oben gerichtete Die Siegelbacken 3, 4 werden nun gegen die nach oben geblasenen Ränder 25 der Zuschnitte 23 bewegt. Gleichzeitig befinden sich die Platten 5, 6 in einer solchen Stellung, dass sie nahe an die aufgerichteten Zuschnittränder 25 heranreichen (Fig. 1).Macaroni has been entered is in a known manner under the sealing jaws 3.4 and the plates 5.6 required. Above the edges of the conveyor cup 22 Tiny parts of the blank 23 are essentially removed with the aid of the blower nozzles 7 The sealing jaws 3, 4 are now directed vertically upwards against the upwards blown edges 25 of the blanks 23 moved. At the same time there are the Plates 5, 6 in such a position that they are close to the erected cutting edges 25 reach (Fig. 1).

Beim Verschwenken der Hebel 1, 2 bewegen sich die Siegelbacken 3, 4 aufeinanderzu und gegen die Platten 5, 6. Dabei drücken letztere die Zuschnittränder 25 gegen die Arbeitsflächen 8, 9 bzw. die Saugöffnungen 10 der Siegelbacken 3,4, wo 8ie mittels Unterdruck festgehalten werden (Fig. 2).When the levers 1, 2 are pivoted, the sealing jaws 3 move, 4 towards each other and against the plates 5, 6. The latter press the cut edges 25 against the work surfaces 8, 9 or the suction openings 10 of the sealing jaws 3, 4, where they are held in place by means of negative pressure (Fig. 2).

Die Siegelbacken 3, 4 werden nun weiter gegeneinander in Siegelstellung bewegt. Gleichzeitig wird der Hebel 15 im Uhrzeigereinn verschwenkt. Dabei rollen die Kurvenrollen 19 an der Leitkurve 21 entlang, so dass sich die Platteh 5, 6 auf bogenförmigen Wagen von den Siegelbacken 3, 4 entfernen (Fig. 3).The sealing jaws 3, 4 are now further against each other in the sealing position emotional. At the same time, the lever 15 is pivoted clockwise. Roll thereby the cam rollers 19 along the guide curve 21 so that the plate 5, 6 on Remove the arched carriage from the sealing jaws 3, 4 (Fig. 3).

Nachdem die Platten 5, 6 aus der, Bewegungsbahn der Siegelbacken 3, 4 entf:ernt sind, schwenken die vollends aufeinanderzu und pressen dabei die Zuschnittränder 25 gegeneinander, worauf der Siegelvorgang beginnen kann. Die Siegelbacken 2,4 können dabei in beliebiger gesigneter Weise beheizt werden. Während des Siegelvergangs wird der an den Saugöffnungen he. herrschende Unterdruck durch das Steuerventil derart abgebaut, dass beim nachfolgenden Lösen der Siegelbacken 3, 4 eine frisch gesiegelte Längssiegelnaht 26 nicht aufgespalten wird (Fig. 4).After the plates 5, 6 from the, movement path of the sealing jaws 3, 4 removed are harvested, they swing completely towards each other and press the cut edges in the process 25 against each other, whereupon the sealing process can begin. The sealing jaws 2.4 can be heated in any signed manner. During the sealing process the at the suction openings he. prevailing negative pressure through the control valve degraded in such a way that when the sealing jaws 3, 4 are subsequently loosened, a fresh sealed longitudinal sealing seam 26 is not split open (FIG. 4).

Die erfindungsgemässe Vorrichtung ist jedoch, wie bereits eingangs erwähnt. auf das beschriebene und dargestellte Ausföhrungsbeispiel, bei dem der Zuschnitt 23 in einem Becher 22 liegend ein. vorbestimmte Menge Füllgut 24 umhüllt, nicht beschränkt, sondern sie kann selbstverstandlich auch dann eingesetzt werden, wenn ein Zuschnitt um einen Formdorn gelegt und zu einem Schlauch geformt und gesiegelt werden soll, der anschliessend an einem Ende verschlossen wird, um so einen Beutel zu bilden.The device according to the invention is, however, as already at the beginning mentioned. on the described and illustrated embodiment, at which the blank 23 lying in a cup 22. predetermined amount of product 24 enveloped, not restricted, but it can of course also be used are when a blank is placed around a mandrel and formed into a tube and is to be sealed, which is then closed at one end in order to so to form a bag.

Das Bewegen der Platten 5, 6 kann ohne weiteres auch mit einem beliebigen anderen als dem beschriebenen Getriebe vorgenommen werden.Moving the plates 5, 6 can easily be done with any other than the gearbox described.
