Description

Verfahren und Vorrichtung zum Herstellen von Böden an Kunststoffröhrchen Es sind bereits Verfahren zur Herstellung von Böden an Kunststoffröhrcben bekannt. Bei einem dieser Verfahren werden die Röhrchen aus einer Kunststoffolie hergestellt, und der gepreßte, durch Spritzgießen hergestellte oder ausgestanzte Boden wird dann angel schweißt. Bei einem anderen Verfahren werden die Becher ganz durch Pressen hergestellt, jedoch kann dieses Verfahren nur bei Bechern Anwendung finden, deren Höhe annähernd gleich ist dem Durchmesser.Method and device for producing floors on plastic tubes Processes for the production of bottoms on plastic tubes are already known. In one of these processes, the tubes are made from a plastic film, and the pressed, injection molded or stamped base is then made angel welds. Another method is to press the cups entirely produced, but this method can only be used for cups, their The height is approximately equal to the diameter.

Durch Spritzgießen kann man viel tiefere Becher herstellen, jedoch muß für jede Bechergröße eine besondere, teure Form benutzt werden. Ein weiteres Verfahren besteht darin, den Rand des Röhrchens zur Herstellung des Bodens durch Falten und Eindrücken zu benutzen. wobei das Schmelzen durch Hochfre quenzstrom bewirkt wird.Much deeper cups can be made by injection molding, however a special, expensive shape must be used for each cup size. Another one Method is to make the bottom through the edge of the tube To use folds and indentations. whereby the melting by Hochfre quenzstrom is effected.

Bekannt ist weiter eine Vorrichtung zum Herstellen von Röhrchenböden aus Kunststoff, die aus einem mit einem ausgehöhlten Gesenk ausgerüsteten Teil zum Umfalzen der erwärmten Ränder am Ende der Röhrchen und einem Hochfrequenz-Verschweißungsteil zum Verschweißen des Kunststoffs, der zum Herstellen des Bodens benötigt wird, besteht. A device for producing tube bottoms is also known made of plastic, which consists of a part equipped with a hollowed-out die for the Fold over the heated edges at the end of the tubes and a high-frequency welding part for welding the plastic that is needed to produce the floor.

Gegenstand der Erfindung ist eine verbesserte Verfahrensweise und eine Vorrichtung zur Massenherstellung von Röhrchenböden. The invention is an improved procedure and a device for the mass production of tube bottoms.

Dieses Verfahren ist durch folgende Vorgänge gekennzeichnet: Es wird ein körniger Kunststoff, wie Polyvinylchlorid, benutzt, mit dem ein Röhrchen nach einem üblichen Verfahren durch Stauchen od. dgl. hergestellt wird. Dieses Röhrchen wird dann in Stücke der gewünschten Länge geschnitten. This procedure is characterized by the following operations: It will a granular plastic, such as polyvinyl chloride, is used, with which a tube is used a conventional process by upsetting od. The like. Is produced. This tube is then cut into pieces of the desired length.

Das Röhrchenstück wird auf einen Dorn gesteckt, der einen Anschlagring trägt. Das vorstehende Ende des Röhrchens wird durch Einbiegen in einem Gesenk vorgeformt, das auf 60 bis 80" C erwärmt ist. Auf das Ende des Dorns, auf dem der Röhrchenboden durch Einliegen vorgeformt ist, wird gegebenenfalls ein zweites flaches Gesenk aufgesetzt, durch das die Falten flachgedrückt werden, wobei auch die Größe des Bodens durch Abkühlen festgelegt wird. Der auf diese Weise gebildete Röhrchenboden wird schließlich durch Hitze, z. B. in einem Hochfrequenzfeld, behandelt. The tube piece is put on a mandrel that has a stop ring wearing. The protruding end of the tube is preformed by bending in a die, which is heated to 60 to 80 "C. On the end of the mandrel on which the bottom of the tube is pre-formed by inserting, a second flat die is put on if necessary, by which the folds are flattened, whereby also the size of the bottom by Cooling down is set. The tube bottom formed in this way eventually becomes by heat, e.g. B. in a high frequency field treated.

Die Vorrichtung zur Durchführung dieses Verfahrens kann vorzugsweise einen Drehtisch aufweisen, auf dem aus leitendem Metall bestehende und mit der Masse elektrisch verbundene Stifte angeordnet sind, welche die Dorne bilden, die zur Aufnahme der Röhrchenstücke aus Kunststoff dienen. Die Dorne werden nacheinander unter feststehende Werkzeuge gebracht, die zum Vorformen und zur Hochfrequenzbehandlung dienen. The device for performing this method can preferably have a turntable on which made of conductive metal and connected to the ground electrically connected pins are arranged, which form the mandrels for receiving the plastic tube pieces are used. The thorns are fixed one after the other under Brought tools that are used for preforming and high frequency treatment.

Die Elektroden zum Erwärmen mittels eines Hoch- frequenzstroms besitzen eine Metallplatte mit einer Verriegelung des Halters, eine Isolierbüchse mit den Abmessungen der Dorne und einen Kondensator, vorzugsweise aus Metall und einem Kunststoff auf Azetatbasis, der sich zwischen den Dornen und der Elektrode befindet. The electrodes for heating by means of a high- own frequency current a metal plate with a lock of the holder, an insulating sleeve with the Dimensions of the mandrels and a capacitor, preferably made of metal and a plastic based on acetate, which is located between the spikes and the electrode.

An Hand der Zeichnung wird nachfolgend das erfindungsgemäße Verfahren zur Herstellung der Röhrchenböden aus Kunststoff näher beschrieben: Fig. 1 ist ein lotrechter Schnitt durch ein aus Kunststoff bestehendes Röhrchenstück; Fig. 2 ist eine Schnittansicht des auf den Dorn gesteckten Röhrchens, über dem sich das zum Vorformen bestimmte Gesenk befindet; Fig. 3 zeigt das Röhrchen nach dem Umfalzen des freien Endes; Fig. 4 zeigt das Röhrchen nach dem Eindrücken des Bodens durch ein flaches Gesenk; Fig. 5 zeigt das Röhrchen unter der Elektrode zum Erwärmen im Hochfrequenzfeld; Fig. 6 ist ein Schnitt durch eine Elektrode zum Erwärmen mittels Hochfrequenzlstroms zum Schmelzen des vorgeformten Röhrchenbodens; Fig. 7 ist ein schematisches Schaubild einer Vorrichtung zur laufenden Herstellung; Fig. 8 ist ein Schnitt durch eine andere Ausführung der Vorrichtung. The method according to the invention is described below with reference to the drawing for the production of the tube bottoms from plastic described in more detail: Fig. 1 is a perpendicular section through a piece of tubing made of plastic; Fig. 2 is a sectional view of the tube placed on the mandrel, over which the to Preforms specific die located; Fig. 3 shows the tube after crimping of the free end; Fig. 4 shows the tube after pressing the bottom through a flat die; Fig. 5 shows the tube under the electrode for heating in the High frequency field; Fig. 6 is a section through an electrode for heating by means High frequency current to melt the preformed bottom of the tube; Fig. 7 is a schematic diagram of an apparatus for ongoing production; Fig. 8 is a section through another embodiment of the device.

Das erfindungsgemäße Verfahren läßt sich an Hand der Fig. 1 bis 6 der Zeichnung erklären. Das Röhrchenstück7, das etwas länger ist als der herzustellende Becher und von einem langen Kunststoffrohr abgeschnitten wird (Fig. 1), wird auf einen Dorn 2 gesteckt, über den es etwa um die Länge9 vorsteht, die durch die Lage des einstellbaren Anschlagrings 8 bestimmt wird. Das aufgesteckte Röhrchenstück wird dann unter das Gesenk 15 gebracht (Fig. 2). Dieses besitzt einen haubenartigen, Hohlraum 22 und wird auf eine Temperatur von 50 bis 800 C erwärmt, bei der das vorstehende Ende des Röhrchenstücks erweicht, ohne zerstört zu werden. Beim Aufdrücken des Gesenks auf das Röhrchenende (Fig. 3) wird die Seitenwand 4 umgelegt und eingedrückt. The method according to the invention can be illustrated with reference to FIGS. 1 to 6 explain the drawing. The tube piece7, which is slightly longer than the one to be produced Cup and cut from a long plastic tube (Fig. 1) is on inserted a mandrel 2, over which it protrudes about the length9, which is due to the situation of the adjustable stop ring 8 is determined. The attached piece of tube is then under brought the die 15 (Fig. 2). This owns a hood-like, cavity 22 and is heated to a temperature of 50 to 800 C, in which the protruding end of the tube piece softens without being destroyed. When the die is pressed onto the end of the tube (FIG. 3), the side wall 4 turned down and pushed in.

Der auf diese Weise vorgeformte Boden 24 gelangt dann unter ein zweites Gesenk 23 (Fig.4), das einen flachen Boden28 aufweist und durch das der vorgeformte Boden gekühlt und verfestigt wird. The bottom 24 preformed in this way then passes under a second one Die 23 (Figure 4), which has a flat bottom 28 and through which the preformed Soil is cooled and solidified.

Das nun geschlossene Röbrchenstück wird unter die Hochfrequenzelektrode 26 gebracht, die durch dielektrische Verlusterwärmung den Boden 24 glättet (Fig. 5). The now closed piece of tubing is placed under the high-frequency electrode 26 brought, which smooths the floor 24 through dielectric heat loss (Fig. 5).

Die Gesenke 15 und 23 ssswie die Elektrode 26 können sehr verschiedenartige Gestalt aufweisen, die von der Gestalt des herzustellen'den Bodens abhängig ist. The dies 15 and 23 and the electrode 26 can be of very different types Have shape that is dependent on the shape of the bottom to be manufactured.

Das Verschweißen erfolgt unmittelbar nach dem Vorformen, solange der vorgeformte Teil des Röhrchenstücks und das obere Ende des Dorns noch eine Temperatur von 18 bis 200 C aufweisen für eine Elektrode einer dem Boden angepaßten Gestalt und Beschaffenheit. The welding takes place immediately after the preforming, as long as the preformed part of the tube piece and the upper end of the mandrel still have a temperature from 18 to 200 C for an electrode of a shape adapted to the soil and texture.

Die Elektrode26 überdeckt in allen Fällen den vorgeformten Teil und bewirkt unter Druck das Verschmelzen durch den Hochfrequenzstrom. The electrode 26 covers the preformed part and in all cases causes the high-frequency current to fuse under pressure.

Die Elektrode26 kann in der in Fig. 6 dargestellten Weise ausgeführt sein. The electrode 26 can be implemented in the manner shown in FIG. 6 be.

Der obere Teil 18 ist die eigentliche Elektrode. The upper part 18 is the actual electrode.

Ein Ring 19 aus Isolierstoff umgibt den oberen Teil des Röhrchens und ist diesem angepaßt. Der Ringl9 wird durch einen Halter 21 festgehalten. Eine Klemmscheibe 25 hält das Ganze zusammen. Ein Kondensator 27 befindet sich zwischen der eigentlichen Elektrode und dem zu verschmelzenden Teil. A ring 19 made of insulating material surrounds the upper part of the tube and is adapted to this. The ring 19 is held in place by a holder 21. One Clamping disk 25 holds the whole thing together. A capacitor 27 is located between the actual electrode and the part to be fused.

Der Kondensator besteht aus einer Scheibe aus thermoplastischem Kunststoff27, beispielsweise aus Zelluloseazetat oder Zellulosetriazetat, und aus einer vorzugsweise metallischen Scheibe 30, jedoch aus einem anderen Metall als die Elektrode. Besteht bei spielsweise die Elektrode aus Hartaluminium, so kann das Metallblatt aus Messing oder Kupfer hergestellt sein oder umgekehrt. The condenser consists of a disc made of thermoplastic material27, for example from cellulose acetate or cellulose triacetate, and preferably from one metallic disc 30, but made of a different metal than the electrode. Consists For example, if the electrode is made of hard aluminum, the metal sheet can be made of brass or copper or vice versa.

Der Vorteil der mit einem Kondensator versehenen Elektrode besteht darin, daß (bei gleichem Energie verbrauch) das Verschmelzen sehr beschleunigt wird. The advantage of the electrode provided with a capacitor is there in that (with the same energy consumption) the fusion is very accelerated.

Die Verkürzung der Schmelzzeit beträgt 1 bis 3 Sekunden.The shortening of the melting time is 1 to 3 seconds.

Die Konstruktion der Maschinen kann beliebig sein, durch welche die mit Röhrchen versehenen Dorne unter die Vorrichtungen zum Vorformen und Fertigmachen gebracht werden können oder welche diese Vorrichtungen an den Dornen vorbeiwandern lassen. The construction of the machines can be any, through which the tubed mandrels under the preforming and finishing devices can be brought or which these devices migrate past the thorns permit.

Die Steuerung dieser Vorgänge kann mechanisch, durch Druckluft, durch Elektromagnete oder durch eine Druckflüssigkeit bewirkt werden.These processes can be controlled mechanically, using compressed air Electromagnets or by a hydraulic fluid.

Es wird nachfolgend an Hand der Fig. 7 eine mechanisch gesteuerte Maschine zur Ausübung des Verfahrens beschrieben: Ein Drehtisch 1 trägt paarweise zusammengestellte Dorne 2, die vorzugsweise abnehmbar sind, aus einem stromleitenden Metall bestehen und elektrisch mit der Masse verbunden sind. A mechanically controlled one is shown below with reference to FIG Machine for carrying out the method described: A turntable 1 carries in pairs assembled mandrels 2, which are preferably removable, from an electrically conductive Are made of metal and are electrically connected to ground.

Über dem Drehtisch sind an bestimmten Stellen des Umfangs Vorrichtungen zum Vorformen und eine Vorrichtung zum Verschweißen mittels Hochfrequenzstrom angeordnet. Above the turntable there are fixtures at certain points on the perimeter arranged for preforming and a device for welding by means of high frequency current.

Die erste Vorrichtung 3 trägt ein GehäuseS mit einem Gesenk und läßt sich auf den zugehörigen Dorn senken. Das Gesenk 15 wird elektrisch durch einen Widerstand 16 erhitzt. Es weist eine becherförmige Aussparung auf, die das Einbiegen der Röhrchenränder erleichtert. The first device 3 carries a housing S with a die and leaves on the associated mandrel reduce. The die 15 is made electrical by a resistor 16 heated. It has a cup-shaped recess that allows the edges of the tube to be bent relieved.

Es kann gegebenenfalls eine zweite Vorrichtung vorgesehen sein, die mit einem Gesenk mit flachem Boden versehen ist und zum Eindrücken und Glätten des Bodens in kaltem Zustand dient. A second device can optionally be provided which is provided with a flat-bottomed die and for indenting and smoothing the Serves soil when cold.

Die dritte Vorrichtung trägt den Kopf 6 eines Hochfrequenzgeräts, das mit abnehmbaren und verschieden geformten Elektroden 26 in Berührung steht. Diese Vorrichtung läßt sich auch zum Formen des Rohrbodens senken. The third device carries the head 6 of a high frequency device, which is in contact with removable and variously shaped electrodes 26. This device can also be lowered to form the tube sheet.

Bei anders als mit einem Hochfrequenzstrom arbeitenden Wärmequellen sind die Elektroden mit einer Wärmequelle verbunden, die zum Erweichen des Teils 24 genügt, damit unter der Einwirkung des Drucks das Verschmelzen erfolgt. With heat sources that work differently than with a high-frequency current the electrodes are connected to a heat source that is used to soften the part 24 is sufficient for the merging to take place under the action of the pressure.

Die Vorrichtungen sitzen fest an einem Ring 14, der drehbar auf dem oberen Ende der Spindel 13 des Tisches 1 gelagert ist und in der oberen Lage durch eine Feder 12 gehalten wird. The devices are firmly seated on a ring 14 which is rotatable on the upper end of the spindle 13 of the table 1 is mounted and in the upper position through a spring 12 is held.

Ein Fußhebel 11, der durch ein biegsames Zugmittel 10 mit dem Ring 14 verbunden ist, bewirkt das Senken der Vorrichtungen 3 zum Vorformen. Die Gesenke 15, die durch die Widerstände 16 auf eine entsprechende Temperatur gebracht werden, biegen rasch den erweichten Rand 9 der Röhrchen ein und bringen ihn dabei in Falten. Während des Niederhaltens des Fußhebels 11 gelangen auch die Elektroden 26 der Vorrichtung 4 zum Fertigmachen mit den vorgeformten Röhrchenhöden 24 in Berührung. Unter der Einwirkung des Hochfrequenzfelds oder der sonstwie übertragenen Wärme schmelzen die Falten der Böden, und die Röhrchen werden fertiggemacht. Der Fußhebel 11 wird dann losgelassen, so daß die Vorrichtungen 3 und 4 wieder gehoben werden. Der Tisch 1 wird um 9()° verdreht, die fertigen Röhrchen werden herausgezogen und durch frische ersetzt, und das Arbeitsspiel wird wiederholt. Die Vorrichtung 3 ist gleitbar auf dem Ringl4 gelagert und wird durch eine Feder 17 beeinflußt. Diese Anordnung gestattet das Senken der Vorrichtung 4 und die Aufrechterhaltung der Berührung mit den Röhrchen. A foot lever 11, which by a flexible traction means 10 with the ring 14, causes the devices 3 for preforming to be lowered. The dies 15, which are brought to an appropriate temperature by the resistors 16, quickly bend the softened edge 9 of the tube and bring it into folds. While the foot lever 11 is being held down, the electrodes 26 also move into the device 4 in contact with the preformed tube hollows 24 for preparation. Under the Melting under the effect of the high-frequency field or otherwise transferred heat the folds of the bottoms, and the tubes are made ready. The foot lever 11 is then released so that devices 3 and 4 are raised again. The table 1 is rotated by 9 () °, the finished tubes are pulled out and replaced with fresh ones replaced and the cycle is repeated. The device 3 is slidable the Ringl4 and is influenced by a spring 17. This arrangement permits lowering the device 4 and maintaining contact with the tubes.

Der drehbar oder verschiebbar gelagerte Tisch und die feststehenden Vorrichtungen zum Vorformen und Fertigmachen können auch durch bewegliche Vorrichtungen und einen feststehenden Tisch ersetzt werden. The rotatable or slidable table and the fixed ones Devices for preforming and finishing can also be provided by moving devices and a fixed table to be replaced.

Die Steuerung der Gesenk- und Elektrodenhalter kann natürlich auch auf andere Weise erfolgen, ebenso können die Elektrodenhalter und die beschriebenen Einzelanordnungen in anderer Weise ausgebildet sein.The control of the die and electrode holders can of course also be used done in a different way, as can the electrode holders and those described Individual arrangements can be designed in a different way.

Eine andere Ausführung der Maschine ist in Fig. 8 dargestellt. Another embodiment of the machine is shown in FIG.

Auf dem Tisch 1 befinden sich beispielsweise sechs Dornpaare 2. An den Stellen werden vom Bedienenden zwei Röhrchen 7 auf beide Dornpaare gesteckt. On the table 1 there are, for example, six pairs of mandrels 2. An The operator places two tubes 7 on both pairs of mandrels.

An der Stelle B sind Gesenke 15 zum Vorformen gemäß Fig. 2 oder Stanzstempel 29 vorgesehen. At the point B there are dies 15 for preforming according to FIG. 2 or punching dies 29 provided.

An der Stelle C sind Gesenke23 zum Flachdrücken gemäß Fig. 4 oder zum Bördeln vorgesehen. At the point C there are dies 23 for flattening according to FIG. 4 or intended for flanging.

An der Stelle D erfolgt das Verschmelzen mittels Hochfrequenzstroms. Bei E werden die fertigen Röhrchen ausgeworfen. At point D, the fusing takes place by means of high-frequency current. At E the finished tubes are ejected.

Der Bedienende verdreht den Tisch ruckweise, und das Arbeiten erfolgt mit einem viel größeren Wirkungsgrad als bei bekannten Verfahren, weil das Verschmelzen sehr rasch stattfindet. The operator turns the table in jerks and the work begins with a much greater efficiency than with known methods, because the fusing takes place very quickly.

Die rasch mit wenig Handarbeit und in sehr kurzer Zeit hergesitellten Röhrchen haben ein schönes Aussehen. Zwischen den Außenwänden und dem Boden ist keine Unterbrechung vorhanden, und Undichtheiten sind nicht zu befürchten, obwohl kein zusätzliches Material aufgebracht wird. Die Röhrchen können mit einem flachen oder einem gewölbten Boden versehen sein. Which are produced quickly with little manual labor and in a very short time Tubes have a nice appearance. Between the outer walls and there is no interruption in the floor, and leaks are not to be feared, although no additional material is applied. The tubes can be connected to a be provided with a flat or a curved base.
