Verfahren und Vorrichtung zur Herstellung von Hohlkörpern aus thermoplastischen Kunststoffen im BlasverfahrenMethod and device for the production of hollow bodies from thermoplastics in the blow molding process
Bei der Herstellung von Hohlkörpern aus thermoplastischen Kunststoffen nach dem Blasverfahren geht man im allgemeinen von einem schlauchförmigen Vorformling aus, der in einer Hohlform zum Fertigteil geformt wird. Sollen beispielsweise flaschenartige Hohlkörper hergestellt werden, so wird das den späteren Flaichenboden bildende Ende des schlauchförmigen Vorformlings durch an den beiden Hälften der Hohlform angebrachte Quetsch- und Schneidkanten zusammengedrückt. Dadurch wird das Ende des Vorformlings zuerst flachgequetscht, worauf bei fortschreitendem Formschluß die einander gegenüberliegenden Innenwände des flachgelegten Vorformlings miteinander verschweißen. Bach dem Schließen der Hohlform und dem Verschweißen des Schlauchendes wird der Vorformling mit Hilfe eines Druckmittels, vorzugsweise Druckluft, aufgeblasen. Während des Aufblasens werden die Wände des warmen zähplastischen Vorformlings so lange gedehnt, bis sie an der gekühlten Wand der Hohlform anliegen und dort ihre endgültige Gestalt bekommen.In the production of hollow bodies from thermoplastics by the blow molding process, one goes in general starting from a tubular preform, which is formed into a finished part in a hollow mold. Shall, for example bottle-like hollow bodies are produced, the end of the tubular body which will later form the flaichen base is Preform pressed together by pinching and cutting edges attached to the two halves of the hollow mold. Through this the end of the preform is first squeezed flat, whereupon the opposing parts as the positive engagement progresses Weld the inner walls of the lay-flat preform to one another. Bach closing the mold and the By welding the end of the tube, the preform is inflated with the aid of a pressure medium, preferably compressed air. During inflation, the walls of the warm viscous preform are stretched until they touch the rest on the cooled wall of the hollow mold and get their final shape there.
Aus wirtschaftlichen Gründen soll der Hohlkörper eine gleichmäßige Wanddicke besitzen. Diese Forderung läßt sich Jedoch bei den bekannten Verfahren nur zum Teil verwirklichen, weil die Schweißnaht am Boden des Hohl -For economic reasons, the hollow body should have a uniform wall thickness. This requirement can be However, only partially realized with the known methods, because the weld seam at the bottom of the hollow -

körpers linienförmig verläuft, so daß der Boden des Hohlkörpers beim Aufblasen ungleichmäßig gereckt wird.' Teilt man die fertige Bodenfläche des Hohlkörpers in Kreisringflächen auf, so ist der Boden längs des Umfanges dieser Kreisringflächen unterschiedlich dick. Mit Rücksicht auf die Festigkeit der schwächsten Bodenstelle werden die übrigen Teile des Bodens zu dick, so daß das Gewicht des Körpers hoher wird, als es erforderlich wäre.body runs linearly, so that the bottom of the hollow body is unevenly stretched when inflated. ' If you share the finished bottom surface of the hollow body in circular ring surfaces, the bottom is along the circumference of these circular ring surfaces different thickness. With regard to the strength of the weakest part of the ground, the remaining parts of the bottom too thick, so that the weight of the body becomes higher than it would be necessary.
Bei einem anderen bekannten Verfahren zur Herstellung von Hohlkörpern wird die Öffnung des zähplastischen schlauchförmigen Vorformlings vor dem Einlegen in die Blasform mit Hilfe einer von der eigentlichen Blasform getrennten Schneid- und Schweißvorriehtung verschweißt. Der Vorformling mit seinem bereits verschlossenen Ende wird in die Hohlform eingelegt und, wie bei dem oben beschriebenen Verfahren, durch Aufblasen weiter verformt. Auch hier verläuft die Schweißnaht linienförmig, in der Regel in diagonaler Richtung, über den ganzen oder größten Teil des Hohlkörperbodens.In another known method for producing hollow bodies, the opening of the viscoplastic tubular Preforms before being placed in the blow mold with the aid of a cutting and cutting device that is separate from the actual blow mold Welding device welded. The preform with its already closed end is placed in the hollow mold and, as in the method described above, further deformed by inflation. Here, too, the weld seam runs linearly, usually in a diagonal direction, over the whole or most of the hollow body floor.
Es wurde auch bereits versucht, die unerwünschte linienförmige Schweißnaht am Boden des Hohlkörpers durch eine sehr kleine Schweißnaht zu ersetzen, die aus einer auf der Längsachse des Vorformlings liegenden Fläche besteht. Beim Aufblasen eines solchen Vorformlings werden alle auf einem zur Hohlkörperachse konzentrischen Kreis liegenden Stellen des Hohlkörperbodens gleichmäßig gereckt, so daß sie eine gleichmäßige Dicke bekommen.Attempts have also been made to remove the undesired linear weld seam at the bottom of the hollow body by a very to replace small weld seam, which consists of a surface lying on the longitudinal axis of the preform. When inflating of such a preform are all points of the lying on a circle concentric to the hollow body axis Hollow body base evenly stretched so that it has a uniform Get fat.

Zur Durchführung dieses Verfahrens sollte eine in Form einer Irisblende arbeitende, aus mehreren dünnen Blechen bestehende Abschneidevorrichtung dienen. Diese Vorrichtung brachte keinen Erfolg, weil ihre Schneidkanten nicht in einer Ebene lagen und weil diese nicht in der für das Verschweißen des Vorformlings notwendigen Breite ausgeführt werden konnten.To carry out this procedure, one should be in the form of a Iris diaphragm working, consisting of several thin sheets of metal cutting device are used. This device did not bring any Success because their cutting edges were not in one plane and because they were not in the one for welding the Preform necessary width could be carried out.
Das erfindungsgemäße Verfahren zur Herstellung von Hohlkörpern aus thermoplastischen Kunststoffen löst die Aufgabe, einen schlauchförmigen, erwärmten zähplastischen Vorformling an einem der beiden offenen Enden vor der letzten Verformung zu beschneiden und in einer in der Längsmitte des Vorformlings liegenden, nahezu punktförmigen Uaht zu verschweißen. Erfindungsgemäß wird der Vorformling gleichzeitig von mindestens drei Seiten in einer senkrecht zu seiner Längsachse liegenden Ebene abgeschnitten und verschweißt.The method according to the invention for the production of hollow bodies made of thermoplastics solves the problem of creating a tubular, heated, viscoplastic preform to be trimmed at one of the two open ends before the last deformation and at one in the longitudinal center of the preform lying, almost punctiform Uaht to be welded. According to the invention, the preform is simultaneously made from at least three sides in a direction perpendicular to its longitudinal axis lying plane cut off and welded.

In den Abbildungen ist eine erfindungsgemäße Vorrichtung zum Abschneiden und Verschweißen von schlauchförmigen Vorformlingen dargestellt und zwar beispielsweise für 6 Schneidbakken. Es zeigen Figur 1 bis 3 das G-erät beim Abschneiden bzw. Verschweißen in drei aufeinanderfolgenden Phasen (offen, halb geschlossen und geschlossen), Fig. 4 einen Querschnitt durch die ganze Vorrichtung und Fig. 5 und 6 zwei Ansichten dieser Vorrichtung in halb offener und geschlossener Stellung. In the figures is a device according to the invention for cutting and welding tubular preforms shown for example for 6 cutting jaws. Figures 1 to 3 show the device being cut or Welding in three successive phases (open, half closed and closed), Fig. 4 shows a cross section through the entire device and Figs. 5 and 6 are two views this device in half open and closed position.
Die Schneidvorrichtung besteht aus 6 Schneidbacken 11 bis 16, deren gerade Schneidkanten 21 bis 26 in jeder Stellung ein regelmäßiges Sechseck einschließen (Fig.1 bis 3)« Jede Schneidbacke wird in auf der Trägerplatte 29 (Fig. 5) angebrachten Führungsnuten 28 geführt und liegt dabei stets an den beiden anliegenden Schneidbacken an, d.h. z.B. die Schneidbacke 11 liegt an der Schneidkante 26 der Backe 16 und an der Kante 32 der Backe 12 (Fig.2). Die Schneidkanten 21 bis 26 und die Kanten 31 bis 36 liegen in einer Ebene. Beim Abschneiden und Verschweißen des schlauchförmigen Vorformlings 7 werden die Schneidbacken 11-bis 16 so bewegt, daß die Fläche des einge-The cutting device consists of 6 cutting jaws 11 to 16, whose straight cutting edges 21 to 26 enclose a regular hexagon in every position (Fig. 1 to 3) «Each cutting jaw is guided in guide grooves 28 provided on the carrier plate 29 (FIG. 5) and is always on the two abutting cutting jaws, i.e. for example the cutting jaw 11 lies on the cutting edge 26 of the jaw 16 and on the edge 32 the jaw 12 (Fig. 2). The cutting edges 21 to 26 and the edges 31 to 36 lie in one plane. When cutting and Welding the tubular preform 7 are the Cutting jaws 11 to 16 moved so that the surface of the

Dabei verengt sich der schlauchförmige Vorformling fortschreitend, bis er schließlich abgeschnitten und verschweißt wird.closed hexagon becomes smaller and smaller (Fig. 2) and itself finally closes (Pig. 3). The tubular preform narrows progressively until it is finally cut off and is welded.
Die Vorrichtung (Fig. 4 bis 6) besteht demgemäß aus den 6 Schneidbacken 11 bis 16 (die Backen 11 und 16 sind der Übersichtlichkeit halber weggelassen), die auf einer Trägerplatte 29 gelagert sind. In der Trägerplatte sind 6 Führungselemente, z.B. gerade Führungsnuten 28 eingefräst, die der Anzahl der Backen bzw. der Schneidkanten entsprechen und zur Führung der Backen dienen. In diesen Führungsnuten werden die Backen 11 bis 16 mit Hilfe von an ihrer Unterseite angebrachten Führungselementen z.B. Zapfen 40 geführt. Hierdurch wird erreicht, daß die Schneidkanten in jeder Stellung der Backen zwischen der größten Öffnung und der Schließstellung stets ein regelmäßiges Sechseck bilden. Die Führungsnuten 28 sind so gerichtet, daß sich die Spitze A einer jeden Schneidkante in radialer Eichtung auf den Mittelpunkt des Vieleckes hinbewegt. Die Schneidbacken werden durch Lenkhebel 41 bis 46 gehalten, die einerseits an den Schneidbacken und andererseits an einem Hing 37 gelenkig befestigt sind. Der Sing 37 ist auf der Trägerplatte mit Hilfe von' Kugeln 30 drehbar gelagert. Durch Drehen des Hinges 37 um den in Fig. 6 angegebenen Winkeloo werden somit die Schneidbacken der Vorrichtung von der Lage größter Öffnung in die Schließstellung gebracht.The device (FIGS. 4 to 6) accordingly consists of the 6 cutting jaws 11 to 16 (the jaws 11 and 16 are omitted for the sake of clarity), which are mounted on a carrier plate 29. Six guide elements, for example straight guide grooves 28, are milled into the carrier plate, which correspond to the number of jaws or the cutting edges and which serve to guide the jaws. The jaws 11 to 16 are guided in these guide grooves with the aid of guide elements, such as pins 40, attached to their underside. This ensures that the cutting edges always form a regular hexagon in every position of the jaws between the largest opening and the closed position. The guide grooves 28 are directed so that the tip A of each cutting edge moves in the radial direction towards the center of the polygon. The cutting jaws are held by steering levers 41 to 46 which are articulated on the one hand to the cutting jaws and on the other hand to a Hing 37. Sing 37 is rotatably mounted on the carrier plate with the aid of balls 30. By rotating the ring 37 by the angle o indicated in FIG. 6, the cutting jaws of the device are thus brought from the position of the largest opening into the closed position.
