Description

Titel: Verfahren und Einriichtung zur Herstellung von Schweissverbindungen zwischen From- und Behälterteilen aus Kunststoff.Title: Process and equipment for making welded joints between molded and container parts made of plastic.

Anwendungsgebiets Die Erfindung betrifft ein Verfahren und die zur Ausübung dieses Veräahrens dienende Einrichtung zur Herstellung von Hohlkörpern und Formteilen aus Kunststoff, beispielsweise Fässern, die aux zwei oder mehrern vorgeformetn Teilen zusammengefügt werden.Field of application The invention relates to a method and to the Exercise of this Veräahrens serving device for the production of hollow bodies and molded parts made of plastic, for example barrels, which aux two or more preformed parts are assembled.

Zweck; Zweck der Erfindung ist die vollattomatische Herstellung von Holhkörpern aus Kunststoff, die wegen ihrer Formgebung nicht aus einem Stüok im Spritzguss-oder Blasverfahren hergestellt werden können.Purpose; The purpose of the invention is the fully automatic production of Holh bodies made of plastic, which because of their shape are not made of one piece in the Injection molding or blow molding can be produced.

Stand der Technik mit Fundstellen: Es sind Einriohtungen und Verfahren bekannt, mit denen brauchbare Schweissverbindungen zwischen Form- und Behälterteilen herstellbar sind. Abgesehen von reinen Klebeverfahren handelt es sich um Verfahren und Einrichtungen, die sich durch Hinleitung von Wärme und Druck auf bestimmte Orte und Zonen der zu verbindenden Formstücke kennzeichnen (DBP 1 115 440). Es ist auch ein Verfahren bekannt, mit den ohne Anwendung von Druck eine Schweissverbindung zwischen zwei Kunststoff. teilen hergestellt werden kann. Dabei wird beispielsweise zwischen zwie zu verbindenden Polyäthylenteilen hohen MOlekulargewichtes eine Folie niederen Molekulargewichtes geletg, die durch @inwirkung von Wärme an die anliegenden verbindungsflächen anschmilst.State of the art with references: There are devices and procedures known with which usable welded connections between mold and container parts can be produced. Apart from pure gluing processes, these are processes and facilities that move heat and pressure to specific locations and mark the zones of the fittings to be connected (DBP 1 115 440). It is also a method is known with which a welded connection is made without the application of pressure between two plastic. parts can be made. For example between two high molecular weight polyethylene parts to be connected a film low molecular weight, which by the action of heat on the adjacent Melt the connecting surfaces.

Die Anwendeung von Druck ist dabei je nach der Formgebung der zu verbindenden Teile mehr oder weniger oder garnicht notwendig (DBP 1 005 720).The use of pressure depends on the shape of the joint Parts more or less or not at all necessary (DBP 1 005 720).

Kritik des Stands der Technik: Wenn die bekannten Verfahren und Einriohtungen auf Verwendbarketi bei vollautomatischen Produktionen von Hohlkörgern, beispielseise Fässer aus zwei Spritsgussteilen untersucht wrden, ergeben sich notwndeige Einriiochtungsaufwendeungen, die im Interesse einer störungsfreine Automatisation der Produktion von beispielsweise Fässern aus Kunststoff, redusiert werden müssen.Criticism of the prior art: If the known methods and devices on usability in fully automatic production of hollow bodies, for example If barrels made of two injection-molded parts were examined, the necessary setting expenses would result, in the interest of a trouble-free automation of the production of, for example Plastic barrels that need to be reduced.

Aufgabe: Wieder auf das Beispiel der automatischen Herstellung von Fässenr aus Kunststoff bezogen, stellt sich die Aufgabe, zwei, aus Spritzgusswerkzeugen entnommene Fasshälften miteinander ausreichend fest zu verschweis sen. Nachdeem die Entnahme von zwei Spritsgussteilen aus den entsprechenden Spritzgusswerdkzeugen und deren mechanische Zusammenfügung mit bekannten Greif- und Transporteinrichtungen vollautomatisch durchführbar ist, haben die beiden Fasshälften eine Station zu durchlaufen, in der sie miteinander zu einem Fass verschweisst werden. Die Darstellung disere Station und deren Funktion kennseichnet die, der Erfindung sugrunde liegende Aufgabe.Task: Again on the example of the automatic production of Barrel made of plastic, the task is to make two, made of injection molding tools removed barrel halves to be welded together sufficiently firmly. Nachdeem the removal of two injection molded parts from the corresponding injection molding tools and their mechanical assembly with known gripping and transport devices can be carried out fully automatically, the two barrel halves have to go through a station, in which they are welded together to form a barrel. The representation of this Station and its function know the task underlying the invention.

Lösung: Diese Aufgabe wird dadurch gelöst, dase die zu verschweissenden Ränder der beispielsweise zu verbindenden Fasshälften durch Wärmeeinwirkung erweicht und mit Druckluft zusammengepresst werden. Es werden erfindungs gemäss zwie Mödglichkeiten der Erzeugung und Anwendung von Wärme zur Erwiechung der miteinander zu verbindenden Fasshälf enränder vorgeschlagen: a. Die Erweichung der Fasshälftenränder durch, von aussen wirkende Wärmequellen. b. Die Erwichung der Verschweissungsflächen durch ein dazwischen liegendes Metallmedium, welches induktiv erhitzt wird.Solution: This task is solved by the fact that the to be welded The edges of the barrel halves to be connected, for example, are softened by the action of heat and compressed with compressed air. According to the invention, there are two possibilities the generation and use of heat to warm the elements to be connected Barrel halves suggested: a. The softening of the barrel halves through, external heat sources. b. The softening of the welding surfaces an intermediate metal medium which is inductively heated.

Beschreibung zweier Ausführungsbeispiele: Zwei Ausführungsbeispiele des erfindungsgemässen Verfahrene und der eintsprechenden Einrichtung zur Ausübung desselben sind in den Zeichungen dargestellt und werden im folgenden näher beschrieben: Es zeigen: Fig. 1 Den Schnitt durch zwie übeinander stehende, miteinander zu verschwissende Fasshälften.Description of two exemplary embodiments: Two exemplary embodiments of the method according to the invention and the corresponding device for exercising The same are shown in the drawings and are described in more detail below: They show: FIG. 1 the section through two standing one above the other to be welded to one another Barrel halves.

Fig.4 Den Schnitt durch zwei übereinander stehende Fasshälften mit einem incht eingelegten sinter- bzw. Schweissringban@.Fig. 4 The section through two barrel halves standing on top of each other with an inched sintered or welded ring band @.

Fig.5 Den Schnitt durch zwei ineinander gefügte Fasshälften mit einem zwischen den Verbindungsflächen einliegenden Sinter- bzw. Schweissringband.Fig. 5 The section through two nested barrel halves with one Sintered or welded ring band inserted between the connecting surfaces.

Bei demd ersten Ausführungsbeispiel gemäss den Fig.1 bis 3 bedient sich das erfindungsgemässe Verfahren zweier Heizquellen (6), die die Fasshältenränder (3) und (4) erweichen. Nachdem eine ausreichende Erweichung der Fasshälftenränder (3) und (4) erreicht ist, werden die beiden Fasshälften mit ihren Rändern ineinander gefahren, wie Fig.2 zeigt, Bei diesem Vorgeng Bildet sich bereite eine Stossnaht (8), wourch zunächst ein leicht dichter Fasshochlraum entstanden ist. Damit sich die Stossnath (8) bilden konnte, musste der Fasshälftenrand (3) konisch ausgebildet sein. Bei der Bewegung der Fasshälften (1) und (2) aus der Position gemäss Fig.1 in die Position gemäss Fig.2 haben sich die Heizquellen (6) vom Fassumfang entfernt, und nach Bildung der Stossnaht (8) umfassen die Ringsegmente (5) die Fassmitte und drücken den erweichten konischen Fass hälftenrand (3) gegen den erweichten Fasshälftenrand (4) während aus der Druckluftdüse (@) durch das Spundloch (10) Druckluft in das Fass gelanft, wie Fig.3 zeigt.In the first exemplary embodiment according to FIGS the inventive method of two heating sources (6), which the barrel halves (3) and (4) soften. After a sufficient softening of the barrel half edges (3) and (4) is reached, the two barrel halves with their edges into each other driven, as Fig.2 shows, with this procedure a butt joint is formed (8), which initially resulted in a slightly dense high barrel space. So that yourself which Stossnath (8) could form, the edge of the barrel half (3) had to be conical be. When moving the barrel halves (1) and (2) out of the position according to FIG In the position according to Figure 2, the heat sources (6) have moved away from the barrel circumference, and after the butt joint (8) has been formed, the ring segments (5) encompass the center of the barrel and press the softened conical barrel half rim (3) against the softened barrel half rim (4) while from the compressed air nozzle (@) through the bunghole (10) compressed air into the Barrel landed, as Fig. 3 shows.

Durch die Druckluft wird der erwcihte Fasshälftenrand (4) gengen den, druch die Ringsemente (5) zylindrisch verformiten Fasshälftenrandzx (3) gedrückt und die Schweissverbindung zwischen den beiden Fasshälften vollendet.The compressed air causes the edge of the drum half (4) to be pressed by the ring elements (5) cylindrically deformed barrel halves edgezx (3) and the welded connection between the two barrel halves is completed.

Bei dem zweiten Ausführungsbeispile gemäss Fig.4 und 5 stehen @ieh gemäse Fig. 4 die zwei Fasshälften auch zunächst getrennt gegenüber und daswischen steht ein metallisches Sinter- bzw. Schwiseringband (5), weiches im Verlauf der Verschweissungsaktion beider Fasshälftenränder um den Fasshäftenrand (4) gelegt wird. Alsdann fährt der Fasshälftenrand (4) mit dem Sinter- bsw.In the second exemplary embodiment according to FIGS. 4 and 5, @ieh 4, the two barrel halves also initially separated opposite and wiped is a metallic sintered or Schwisringband (5), soft in the course of the Welding action of both drum half edges placed around the drum half edge (4) will. Then the drum half edge (4) moves with the sintered bsw.

Schwdeissrigband induktive erwärmt wird. Bei geeigneter Präparation des Sinter- bzw. Schweiserin; bendes sintert der Kunststoff beidseitig des Sinter- bzw. Schweiserinbandes an, während aus der Druokulftdüse (9) durch des Spundloch (10) Druckluft in den Fasshohlraum gelangt und die Verbindungsflächen andrücket. Dabei vollendet sich die ausreichande Verschweissung der beiden Fashälften.Schwisringband (5) in the edge of the barrel half (3) and the plugged together Fasahälften druchfahren the electromagnetic field of the induction coil (6), whereby the metallic sintered or Schwdeissrigband is heated inductively. With suitable preparation of the sinter or welder; At the end of the day, the plastic sinters on both sides of the sintered or welded band while from the Druokulftdüse (9) through the bunghole (10) compressed air into the Barrel cavity arrives and presses the connecting surfaces. This is accomplished the sufficient welding of the two halves of the face.

Bei einer engmaschigen Durchlöcherung des Sinter- bzw Schweisering bandes kann statt der Ansinterung der Kunststofflächen auch eine direkte Verschwissung der Kunststofflächen durch die Druchlöcherung des Sinter- bzw.With a close-meshed perforation of the sintered or welding ring Instead of sintering the plastic surfaces, the tape can also be welded directly the plastic surfaces through the perforation of the sinter or

Schweizsringbandes erreicht werden.Switzerland ring band can be reached.

Erzielbare Vorteile: Zunächst wieder auf das Beispiel der Kunststoff- Fassherstellung kommend, liegt der primäre Vorteil darin, dass mit dem erfindungsgemässen Verfahren und der entsprechenden @inriehtung zwei auf dem Spritzgnsswege erstellte Fasshälften mit wenigen automatisch ausführbaron Operationen hinreiohend fest miteinander verschwisst werden können, wobei das so erstellte Fass als Sprètzgussprodutkt mit allen notwendigen Anformungen versehen sein kann, wie die Verstärkungen der stark beanspruchten stellen und Zonen oder auch der Spundlochausbildung und der verstärkten Rollreifen (7), was sich mit anderen Herstellungsverfahren nicht verwirklichen lässt. Dabei werden durch das erfindungsgemässe Verfahren und der entsprechenden Eincrichtung erstrebenswert wirtschaftlich kurse Operationszyklen erreicht.Achievable advantages: First of all, let's go back to the example of plastic Coming barrel production, the primary advantage is that with the inventive Process and the corresponding @inriehtung two created on the Spritzgnssweg Barrel halves with a few automatically executable operations tightly together can be welded, with the barrel created in this way as an injection-molded product all necessary formations can be provided, such as the reinforcements of the strong stressed places and zones or the bunghole formation and the reinforced Rolled tires (7), which cannot be achieved with other manufacturing processes.
