Verfahren und Vorrichtung zur Herstellung von Behältern aus vorgefertigten nahtlosen oder längs geschweißten Kunststoffschläuchen Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Herstellung von Behältern aus vorgefertigten nahtlosen oder längs geschweißte Kunststoffschläuchen. die im gefüllten Zustand mittels Schweißbacken unter Verwendung von Druck und Wärme durch quer liegende Schweißnähte als Verschluß von Behälter zu Behälter unterteilt werden. Method and device for the production of containers from prefabricated seamless or longitudinally welded plastic tubing The invention relates to a method and an apparatus for producing containers from prefabricated seamless or lengthways welded plastic hoses. those in the filled state by means of welding jaws using pressure and heat through transverse welding seams be divided as a closure from container to container.
Solche Querschweißungen setzen den Widerstand der Schlauchwandung an den Schweißstellen herab, so daß bei Vorhandensein eines unter Druck stehenden Füllgutes ein Reißen der Schlauchwandung an den Schweißstellen nur zu vermeiden ist, wenn die Wandung des Schlauches verhältnismäßig stark gewählt wird. Such cross welds set the resistance of the hose wall down at the welds so that in the presence of a pressurized Only to avoid tearing of the hose wall at the welding points is when the wall of the hose is chosen to be relatively strong.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, das die Herstellung von solchen prall gefüllten Behältern aus verhältnismäßigdiinnwandigenKunststoffschlauchen ermöglicht. The present invention is based on the object of a method to create the production of such bulky containers from relatively thin-walled plastic tubing enables.
Das Verfahren gemäß der Erfindung besteht darin, daß zur Ausführung der Verschlußschweißung und/ oder einer Konturenschweißung das auf Schweißtemperatur erwärmte Schlauchmaterial an der Schweißnaht seitlich verdrängt wird, so daß zur Erhöhung der Nahtfestigkeit entlang der Naht sich eine wulstartige Verstärkung bildet. The method according to the invention consists in that for execution the closure weld and / or a contour weld to the welding temperature heated hose material is displaced laterally at the weld seam, so that for Increasing the seam strength along the seam a bead-like reinforcement is formed.
Durch die Verwendungsmöglichkeit dünnwandiger Kunststoffschläuche wird eine wesentliche Materialersparnis, mithin eineVerminderung desHerstellungspreises solcher Behälter erzielt. Außerdem werden die bei dickwandigen Kunststoffschläuchen auftretenden Schwierigkeiten beim Schweißen vermieden. Due to the possibility of using thin-walled plastic hoses becomes a significant material saving, hence a reduction in the manufacturing price such container achieved. In addition, the thick-walled plastic hoses occurring difficulties during welding avoided.
Um eine möglichst pralle Füllung des Behälters zu erhalten, wird nach einem weiteren Kennzeichen der Erfindung der gefüllte Schlauch hinter der Stelle der auszuführenden Verschlußschweißung abgeklemmt, woraufhin die Verschlußschweißung erst beginnt. In order to obtain the fullest possible filling of the container, according to a further characteristic of the invention, the filled hose behind the point the closure weld to be carried out is clamped, whereupon the closure weld only begins.
Die Vorrichtung zur Durchführung des Verfahrens gemäß der Erfindung mit paarweise zusammenwirkenden, symmetrisch zueinander ausgebildeten Schweißbacken ist dadurch gekennzeichnet, daß die Arbeitsflächen der Schweißbacken konvex geformt sind. The device for performing the method according to the invention with mutually symmetrical welding jaws that work together in pairs is characterized in that the working surfaces of the welding jaws are convex in shape are.
Nach einem anderen Kennzeichen der Erfindung sind die Schweißbacken mit den im Abstand von ihnen liegenden Klemmbacken bewegungsmäßig gekoppelt, und der Abstand zwischen Klemmbacken und Schweißbacken übersteigt nicht das Zwanzigfache der Länge eines Einzelbehälters. According to another characteristic of the invention are the welding jaws coupled in terms of movement to the clamping jaws located at a distance from them, and the distance between clamping jaws and welding jaws does not exceed twenty times the length of a single container.
Die Erfindung wird an Hand der Zeichnung näher erläutert. Es zeigt Fig. 1 eine Seitenansicht, teilweise im Schnitt, eines Schlauches, von dem ausgegangen wird. The invention is explained in more detail with reference to the drawing. It shows Fig. 1 is a side view, partially in section, of a hose starting from will.
Fig. 2 einen Längsschnitt einer Kette von Behältern. die aus dem Schlauch hergestellt sind. Figure 2 is a longitudinal section of a chain of containers. those from the Hose are made.
Fig. 3 eine Ansicht eines breiten Schlauchstückes einer Mehrzahl von in prallen Reihen liegenden Behältern, Fig. 4 eine Ansicht mehrerer geradlinig aneinandergereihter Behälter. Fig. 3 is a view of a wide piece of tubing of a plurality of containers lying in tight rows, FIG. 4 is a view of several straight lines container lined up.
Nach Fig. 1 wird zur Herstellung der Behälter von einem langen, biegsamen Schl, auch 1 ausgegangen, der vorzugsweise aus Polyvinylchlorid besteht und am einen Ende mittels einer Querschweißung 2 verschlossen ist. Der Schlauch wird in vertikaler Stellung mit einer flüssigen Substanz gefüllt, die auf die Schlauchwandung einen gewissen Druck ausübt. According to Fig. 1, the container is made from a long, flexible one Schl, also assumed 1, which preferably consists of polyvinyl chloride and on one The end is closed by means of a transverse weld 2. The hose is in a vertical position Position filled with a liquid substance that is placed on the hose wall exerts some pressure.
Der Schlauch 1 wird hierauf, wie in Fig. 2 dargestellt, von einem nicht gezeigten Schweißmatrizenpaar erfaßt, das über einen Bereich 3 eine Zusammenpressung der Wandung des Schlauches 1 und das Zusammenschweißen der Innenflächen hewirkt, wodurch nacheinander voneinander abgeteilte Behälter entstehen. Diese Schweißungen werden vorzugsweise mittels Backen, die durch elektrischen Hochfrequenzstrom gespeist sind, ausgeführt, wobei jedoch die Anwendung jeglicher anderer Preßorgane vorbehalten wird. welche durch eine andere Wärmequelle geheizt werden können. The hose 1 is then, as shown in Fig. 2, of a Detects not shown welding matrix pair, which over a region 3 a compression the wall of the hose 1 and the welding together of the inner surfaces works, which results in containers that are separated from one another. These welds are preferably by means of jaws, which are fed by high frequency electrical current are performed, but the use of any other pressing members reserved will. which can be heated by another heat source.
Die Flüssigkeit wird dabei von den flachgepreßten Bereichen 3 in die Behälter 4 verdrängt. The liquid is thereby of the flattened areas 3 in the container 4 displaced.
Der durch die Schweißbacken während des Schweißens ausgeübte Druck ist derart bemessen, daß die Dicke des thermoplastischen Werkstoffes im erweichten Zustand durch Preßwirkung eine zumindest 20°/oige Verminderung des Ausgangswertes erfährt. The pressure exerted by the welding jaws during welding is dimensioned such that the thickness of the thermoplastic material is softened in the Condition due to the pressing effect, an at least 20% reduction in the initial value learns.
Das Profil der Schweißbacken ist so gewählt, daß das erwärmte Schlauchmaterial an der Schweißnaht seit- lich verdrängt wird, um zur Erhöhung der \Tahtfestigkeit entlang der Naht eine wulstartige Verstärkung 5 zu bilden. Die Arbeitsflächen der Backen sind dazu konvex geformt.The profile of the welding jaws is chosen so that the heated hose material at the weld seam Lich is displaced in order to increase the The strength of the seam is to form a bead-like reinforcement 5 along the seam. The work surfaces the jaws are convex in shape.
Hierdurch werden gerade die Stellen verstärkt. die den größten Beanspruchungen ausgesetzt sind. This just strengthens the places. the most demanding are exposed.
Die Schweißungen werden, vom unteren Schlauchende beginnend, aufeinanderfolgend ausgeführt. Die mit nüssigem oder pastenartigem Gut gefiillten Lehälter 4 hängen kettenartig aneinander. Die Behälter kcinnen natiirlich die verschiedenartigsten Umrißformen erhalten. Voraussetzung ist, daß dieAusgangsform entsprechendeAbmessungenbesitzt. Die 13ehälter können ferner einzeln oder in Gruppen hergestellt werden, wobei diese Behälter mittels der sie. umgebenden Flächen aneinandergereiht sind. The welds are consecutive, starting from the lower end of the hose executed. The containers 4 filled with nutty or paste-like material hang like a chain to each other. The containers can, of course, be of the most varied types Outlines received. The prerequisite is that the initial shape has the appropriate dimensions. The containers can also be produced individually or in groups, with these Container means of them. surrounding surfaces are strung together.
Nach Fig. 3 wird ein ungefülltes Schlauchstück 6 durch Schweißlinien in Behälter 7 unterteilt, dei-eii Spitzen 8 in einen Verbindungskanal 9 miincien, der die Behälter miteinander verl) indet und der bis zum Rand des Schlauchstückes 6 verläuft. According to Fig. 3, an unfilled piece of hose 6 is welded divided into container 7, dei-eii tips 8 in a connecting channel 9 miincien, the one that leaves the containers with one another and that one up to the edge of the hose piece 6 runs.
Zur Bitdung der Behälter wird vorteilhaft komprimierte Luft oder ein anderes Gas in das Schlauchende eingeführt. Das gasförmige Medium wird im Schlauchstiick eingeschlossen. wozu dieses an allen Seiten durch Schweißungen luftdicht verschlossen wird. Hierauf werden Schweißungen ausgeführt, die den Umrißlinien der Behälter folgen. Compressed air or compressed air is advantageously used to form the container another gas introduced into the end of the hose. The gaseous medium is in the hose piece locked in. for which this is hermetically sealed on all sides by welds will. This is followed by welds that follow the contours of the containers.
Es kann auch die gesamte Flache, welche die einzelnen Behälter umgibt. geschweißt werden. Die hierdurch erhaltenen Hohlkörper können jede beliebige, dem Verwendungszweck entsprechende Form aufwei sen. It can also cover the entire area that surrounds the individual containers. be welded. The hollow body obtained in this way can be any, the Appropriate form aufwei sen.
Die Behälter können auch in der Längsrichtung angeordnet werden, wie in Fig. 4 dargestellt, wo von einem rohrförmigen Schlauch ausgegangen wird. Um die miteinander in Verbindung stehenden I3ehälter nach dem Füllen abzuteilen, werden in den Bereichen 10 zusätzliche Schweißungen 11 ausgeführt. The containers can also be arranged lengthways, as shown in Fig. 4, where a tubular hose is assumed. In order to divide the connected containers after filling, additional welds 11 are carried out in the areas 10.
Beim Ausführungsheispiel nach Fig. 3 wird nur eine einzige geradlinige Abschlußschwießung ausgeführt. die der Achse des Verbindungskanals 9 folgt. Die darin enthaltene Fliissigkeit wird durch Preßwirkung der Schweißelektroden verdrängt. In the embodiment according to FIG. 3, only a single straight line is used Final weld carried out. which follows the axis of the connecting channel 9. the The liquid contained therein is displaced by the pressing action of the welding electrodes.
Um die Behälter nach Fig. 3 zu fiillen, wird die Fliissigkeit vorteilhafterweise mittels eines Rohres eingeführt, welches bis ans Ende des Kanals 9 reicht, das. während sich die Behälter der Reihe nach anfüllen, schrittweise zuriickgezogen wird. In order to fill the container according to FIG. 3, the liquid is advantageously introduced by means of a tube which extends to the end of the channel 9, the. as the containers fill up in sequence, is gradually withdrawn.
Die erfindungsgemäß verstärkte Schweißnaht erlauht eine besonders pralle Füllung der Behälter. Der Schlauch wird hierzu an einer von der Schweißstelle sehr geringen Entfernung abgeklemmt, und zwar bevor die Schweißmatrizen oder aber die durch elektrischen Hochfrequenzstrom gespeisten Elektroden zur Schweißung aufeinandergepreßt werden. Die Klemmbacken sind vorteilhaft mit den Schweißmatrizen oder Elektroden gekoppelt. Die Klemmbacken verhindern den Rückfluß der Flüssigkeit, die sich zwischen der schon geschweißten Stelle und der abgeklemmten Stelle be- findet. Die abgeklemmte Stelle wird ihre rohrartige Form, sobald der Druck der Klemml) acken gelockert wird, dank der Nacligiebigkeit des thermoplastischen Schlauches und infolge des auf dessen Innenwände durch die Flüssigkeit ausgeiihten Druckes wieder annehmen. Das beste Resultat wird erzielt, wenn die Entfernung zwischen den Klemmbacken und den Schweißbacken das Zwanzigfache der Lange eines Einzeibehälters nicht übersteigt. The weld seam reinforced according to the invention permits a special one full filling of the container. The hose is for this purpose at one of the welding point pinched off a very small distance, either before the welding dies or else the electrodes fed by high-frequency electrical current are pressed together for welding will. The jaws are advantageous with the welding dies or electrodes coupled. The jaws prevent the backflow of the liquid that is between the already welded point and the disconnected point finds. The disconnected Position becomes tubular as soon as the pressure on the clamps is loosened, thanks to the flexibility of the thermoplastic hose and as a result of it The inner walls reassume the pressure exerted by the liquid. The best Result is achieved when the distance between the clamping jaws and the welding jaws does not exceed twenty times the length of a single-use container.
Das Verfahren ermöglicht die Herstellung von Behältern, deren Wände eine größtmögliche Spannung aufweisen, indem der innere Druck des Füllgutes an die Grenze der Zerreißfestigkeit der Behälterwandung heranreichen kans. The method allows the manufacture of containers, the walls of which have the greatest possible tension by applying the internal pressure of the product to the The limit of the tensile strength of the container wall can be approached.
