Description

Vorrichtung zum Herstellen einer am Umfang von rohrförmigen Kunststoffolien verlaufenden Ringnaht Die Erfindung betrifft eine Vorrichtung zum Herstellen einer am Umfang von rohrförmigen Kunststofffolien verlaufenden Ringnaht mit einem Element, das an seinem Umfang durch im wesentlichen ebene Flächen begrenzt ist, die dazu dienen, mit Hilfe der ebenen Preßkante von gegen die ebenen Umfangsflächen des Elementes bewegbaren Schweißorganen je einen Abschnitt der Ringnaht an den auf das Element umfangsmäßig aufbringbaren rohrförmigen Kunststoffolien herzustellen. Device for the production of a tubular plastic film on the circumference running ring seam The invention relates to a device for producing a ring seam with an element running on the circumference of tubular plastic films, which is limited on its circumference by essentially flat surfaces, the to serve, with the help of the flat pressing edge of against the flat peripheral surfaces of the element movable welding organs each have a section of the ring seam on the element To produce circumferentially applicable tubular plastic films.

Es ist eine solche Vorrichtung bekannt, bei der zwei Schweißorgane oberhalb und unterhalb eines plattenförmig ausgebildeten Elementes bewegbar angeordnet sind, mit denen je etwa die Hälfte der Ringnaht hergestellt wird. Such a device is known in which two welding organs arranged movably above and below a plate-shaped element are, with each of which about half of the ring seam is produced.

Zweck der Erfindung ist, eine Vorrichtung der genannten Art zu schaffen, die sich im Gegensatz zur genannten bekannten Vorrichtung eng an die bestehenden Schweißvorrichtungen mit nur einem einzigen Schweißorgan und einem ebenen Tisch anschließt, die zur Herstellung von Schweißverbindungen an ebenen Folien bestimmt sind, so daß diese bestehenden Vorrichtungen in einfacher Weise in die erfindungsgemäße Vorrichtung umgebaut werden können. Auch bezweckt die Erfindung, die Vorrichtung so auszubilden, daß die richtige Lage der zu schweiß enden rohrförmigen Folie bei der Herstellung der Ringnaht leicht kontrolliert werden kann. The purpose of the invention is to create a device of the type mentioned, which, in contrast to the known device mentioned, closely follow the existing ones Welding devices with only a single welding organ and a flat table which is intended for the production of welded joints on flat foils are, so that these existing devices in a simple manner in the invention Device can be rebuilt. The invention also aims the device to train so that the correct position of the tubular film to be welded at the production of the ring seam can be easily controlled.

Nach der Erfindung ist das Element auf dem freien Ende einer nur einseitig befestigten bzw. gelagerten Welle derart ruckweise drehbar angeordnet, daß die ebene Preßkante nur eines einzigen Schweißorgans nacheinander gegen jeden der auf den ebenen Umfangsflächen des Elements aufgbsachten Ringnahtab schnitte zur Wirkung bringbar ist. According to the invention, the element is only one on the free end shaft fastened or mounted on one side in such a way that it can be rotated jerkily, that the flat pressing edge of only a single welding organ successively against each other the Ringnahtab cut on the flat peripheral surfaces of the element can be brought into effect.

In einer vorteilhaften Ausführungsform begrenzen die ebenen Umfangsflächen des scheibenförmig ausgebildeten Elementes, in Richtung der Drehachse des Elementes gesehen, zusammen ein gleichseitiges Vieleck, vorzugsweise ein Dreieck. Dadurch schneiden die ebenen Flächen sich, so daß die auf diesen Flächen hergestellten Abschnitte der Ringnaht sich nahezu berühren und eine praktisch geschlossene Ringnaht erhalten wird. In an advantageous embodiment, the flat peripheral surfaces delimit of the disc-shaped element, in the direction of the axis of rotation of the element seen, together an equilateral polygon, preferably a triangle. Through this the flat surfaces intersect, so that the sections made on these surfaces the ring seam almost touch each other and get a practically closed ring seam will.

Weitere Merkmale der Erfindung sind aus der nachfolgenden Beschreibung einer Ausführungsform der erfindungsgemäßen Vorrichtung an Hand der Zeichnung zu entnehmen. Es zeigt Fig. 1 die Seitenansicht eines Teiles der Schweißvorrichtung teilweise im Schnitt, Fig. 1 a den Schnitt nach der Linie I-I in der Fig. 4 eines Teiles der Vorrichtung und Fig. 2 die beim Schweißen zusammenarbeitenden Teile in der Vorderansicht. Further features of the invention are evident from the description below an embodiment of the device according to the invention with reference to the drawing remove. 1 shows the side view of part of the welding device partially in section, Fig. 1 a the section along the line I-I in Fig. 4 of a Part of the device and FIG. 2 shows the parts that work together during welding the front view.

Ein an der Unterseite mit einer ebenen Preßkante 2 versehenes Schweißorgan 1 ist mit einem bestimmten, gegebenenfalls einstellbaren Hub in einer Führung der Schweißvorrichtung bewegbar. Ein dreieckiges Element 3 ist auf einer Welle 4 drehbar angeordnet, die an einer Stütze 5 befestigt ist. Das Element 3 wird mittels einer Feder 6 und einer mit einem Bund versehenen Buchse 7 gegen eine Mutter 8 angedrückt, die mittels einer zweiten Mutter 8 a gesichert ist. Nach Lösung der Mutter 8, 8 a kann man das Element 3 ohne weiteres gegen ein Element anderer Form oder Größe auswechseln. Die Stütze 5 ist verschiebbar in entsprechenden Nuten 9 eines Gestells 10 angeordnet und kann mittels Schrauben 11 gesichert werden, wodurch das Schweißorgan 1 mit unverändertem Hub auch mit anderen Elementen zusammenarbeiten kann. A welding element provided with a flat pressing edge 2 on the underside 1 is with a certain, optionally adjustable stroke in a guide of the Movable welding device. A triangular element 3 is rotatable on a shaft 4 arranged, which is attached to a support 5. The element 3 is by means of a Spring 6 and a sleeve 7 provided with a collar pressed against a nut 8, which is secured by means of a second nut 8 a. After solving the mother 8, 8 a one can the element 3 easily against an element of a different shape or size replace. The support 5 is displaceable in corresponding grooves 9 of a frame 10 arranged and can be secured by means of screws 11, whereby the welding organ 1 can also work with other elements with an unchanged hub.

Das Element 3 hat an seinem Umfang eine ununterbrochene Nut 13 innerhalb der ebenen Fläche 12. Die Nut 13 ist an beiden Seiten von Rändern 12a, 12 b begrcnzt. Der Rand 12a wirkt mit dem Schweißorgan 1 zusammen. The element 3 has an uninterrupted groove 13 inside on its periphery the flat surface 12. The groove 13 is limited on both sides by edges 12a, 12b. The edge 12a interacts with the welding organ 1.

Das in den Figuren dargestellte Element 3 ist zum Anbringen eines elastischen Bandes 16 in einen Saum längs des Umfanges eines rohrförmigen, aus einer Kunststoffolie bestehenden Körpers 15 sehr geeignet. The element 3 shown in the figures is for attaching a elastic band 16 in a hem along the circumference of a tubular, made of a Plastic film existing body 15 very suitable.

Dazu wird der rohrförmige Körper 15 umfangsmäßig auf das Element 3 aufgebracht, dessen Umfangslänge etwa ebenso groß wie, vorzugsweise aber etwas größer als die Umfangslänge des rohrförmigen Körpers 15 ist. Darauf wird das elastische Band 16 in gedehntem Zustand um den rohrförmigen Körper 15 in die Nut 13 gelegt und wird der das Band 16 überlappende Teil (15' in Fig. 1) des Körpers 15 iiber das Band 16 zurückgeschlagen. Durch Herstellung einer Schweißverbindung zwischen dem zurückgeschlagenen Teil 15' und dem darunterliegenden Teil des rohrförmigen Körpers 15 mit Hilfe des Schweißorgans 1 kann man dann den das elastische Band 16 enthaltenden Saum schließen, wozu man das Element 3 zwei mal um 1200 verdrehen muß. Die Nut 13 im Element 3 erleichtert die richtige Anbringung des elastischen Bandes 16, während der iiberragende Rand 12 b die Bildung eines Saumes gleichmäßiger Breite gewährleistet.For this purpose, the tubular body 15 is circumferentially on the element 3 applied, the circumferential length of which is approximately as large as, preferably but is slightly larger than the circumferential length of the tubular body 15. On it will the elastic band 16 in the stretched state around the tubular body 15 in the Groove 13 is placed and becomes the part (15 'in Fig. 1) of the body which overlaps the band 16 15 fought back over belt 16. By making a welded joint between the turned back part 15 'and the underlying part of the tubular Body 15 with the aid of the welding organ 1 can then be fitted with the elastic band 16 including the hem, for which you have to twist the element 3 two times by 1200. The groove 13 in the element 3 facilitates the correct attachment of the elastic band 16, while the protruding edge 12b forms a seam of uniform width guaranteed.

Zur Befestigung eines rohrförmigen Körpers an einem zweiten mehr oder weniger rohrförmigen Körper, z. B. eines Ärmels an dem Armellochteil eines Regenmantels, bringt man die beiden rohrförmigen Körper mit ihren zu verschweißenden Teilen iibereinander umfangsmäßig auf das Element 3 auf, wonacll man die aufeinanderliegenden Umfangsteile der rohrförmigen Körper auf jeder der ebenen Flächen des Elementes 3 verschweißt. Während des Schweißvorganges können die rohrförmigen Körper mit Hilfe eines elastischen Bandes in ihrer Lage auf dem Ele ment 3 gehalten werden. For attaching a tubular body to a second more or less tubular body, e.g. B. a sleeve on the armhole part one Raincoat, you bring the two tubular bodies with their to be welded Divide over one another circumferentially on the element 3, then one on top of the other Peripheral parts of the tubular bodies on each of the flat surfaces of the element 3 welded. During the welding process, the tubular body can with the help an elastic band can be held in position on the element 3.

Das Element 3 hat zu seiner Sicherung in den drei während des Schweißvorganges erforderlichen Lagen drei Ausnehmungen 17. Die auf der Welle 4 längsverschiebbare Buchse 7 ist mittels einer Schraube 19 gegen Drehung gesichert, die in eine Längs nut 20 der Welle 4 hineinragt. An dem sich gegen das Element 3 abstützende Bund der Buchse 7 sind drei Vorsprünge 18 angeordnet, die bei den drei gewünschten Lagen des Elementes 3 in dieAusnehmungenl7 einschnappen. The element 3 has to be secured in the three during the welding process required layers three recesses 17. The longitudinally displaceable on the shaft 4 Socket 7 is secured against rotation by means of a screw 19, which in a longitudinal groove 20 of the shaft 4 protrudes. On the collar supported against element 3 the socket 7 three projections 18 are arranged in the three desired positions of the element 3 snap into the recesses 7.

Da die Buchse 7 nachgiebig gegen das Element 3 angedrückt wird und die Vorsprünge 18 abgeschrägt bzw. abgerundet sind, kann man das Element 3 leicht verdrehen. Nichtdestoweniger ist das Element 3 in jeder der für den Schweißvorgang erforderlichen Lagen genügend gesichert.Since the bush 7 is pressed resiliently against the element 3 and the projections 18 are beveled or rounded, the element 3 can be easily twist. Nonetheless, element 3 is in each of those for the welding process sufficiently secured.

Das Element 3 kann auch in anderer Weise drehbar angeordnet sein. Es kann z. B. mit einer Welle verschraubt sein, die sich in einem Lager drehen und gegebenenfalls in verschiedenen Lagen gesichert werden kann. The element 3 can also be rotatably arranged in another way. It can e.g. B. be screwed to a shaft that rotate in a bearing and can be secured in different positions if necessary.

Wird die zum Schweißen erforderliche Hitze mit Hilfe eines Hochfrequenz-Wechselfeldes erzeugt, so wird man das Element 3 an Erde legen und das Schweißorgan 1 mit der Spannungsklemme des Hochfrequenzgenerators verbinden. Vorzugsweise versieht man die Preßkante 2 des Schweißorgans und die ebenen Flächen 12 des Elementes dann mit Streifen aus einem hitzebeständigen Kunststoff, z. B. Polytetrafluoräthylen. Is the heat required for welding with the help of a high-frequency alternating field generated, so you will put the element 3 on earth and the welding organ 1 with the Connect the voltage terminal of the high-frequency generator. Preferably one does the pressing edge 2 of the welding member and the flat surfaces 12 of the element then with Strips of a heat-resistant plastic, e.g. B. polytetrafluoroethylene.

Der scheibenförmige Teil des Elementes 3 kann auch die Form eines Vielecks mit vier oder mehr Seiten haben, die vorzugsweise gleich lang sind oder wenigstens in gleichen Entfernungen von der Drehachse liegen. The disk-shaped part of the element 3 can also have the shape of a Polygons with four or more Have sides that are preferably of equal length or are at least equidistant from the axis of rotation.
