Description
Maschine zum Herstellen gefüllter Beutel Die Erfindung betrifft eine Maschine zum Herstellen gefüllter Beutel. Es sind schon solche Maschinen oder Vorrichtungen zum Abpacken von pulverigem, körnigem, flüssigem oder pastenförmigem Füllgut bekanntgeworden, bei denen eine Folie über eine Formschulter und über ein gleichzeitig als Füllrohr dienendes Formrohr zu einem Schlauch gezogen wird.Machine for Making Filled Bags The invention relates to a Machine for the production of filled bags. There are already such machines or devices became known for the packaging of powdery, granular, liquid or pasty contents, in which a film over a forming shoulder and over a at the same time as a filling tube Serving form tube is drawn into a hose.
Im besonderen sind derartige Vorrichtungen bekanntgeworden, bei denen die Längsnaht des Schlauches durch einen länglichen Stempel schrittweise in Abhängigkeit vom -Folienabzug impulsgeschweißt wird. Dabei besorgen den Schlauchabzug, den oberen und unteren Querverschluß der Beutel und deren Abschneiden zwei zangenartig gegeneinander und um die Beutellänge auf und ab bewegte Schweiß- und Schneidbacken. In particular, such devices have become known in which the longitudinal seam of the hose gradually depending on an elongated punch is pulse welded from the film take-off. Get the hose trigger, the upper one and lower transverse closure of the bags and their cutting off two tongs against each other and welding and cutting jaws moved up and down the length of the bag.
Die Impulsschweißung der Längsnaht, bei der die Aufheizung des vom Stempel isoliert getragenen und aus einem massearmen Metallstreifen bestehenden Heizbandes und die Schweißberührung nur etwa 2/io Sekunden dauert, ist für besonders dünne Folien, z. B. aus Polyäthylen, der Schweißung durch eine dauernd beheizte Rolle vorzuziehen, da solche Folien von wenigen Mikron Stärke sich unter der Heizrolle zu sehr erweichen und beim Abziehen zerreißen. The pulse welding of the longitudinal seam, in which the heating of the from Stamp worn in isolation and consisting of a low-mass metal strip The heating tape and the sweat contact only lasts about 2/10 seconds is for special thin foils, e.g. B. made of polyethylene, the weld by a continuously heated Roll to be preferred, as such films, which are a few microns thick, can be placed under the heating roller soften too much and tear when peeled off.
Nachteilig war jedoch bei der Impulsschweißung gegenüber der vielfach bekanntgewordenen Schweißung durch beheizte Rollen bislang, daß sie kein kontinuierliches Arbeiten gestattete, da der Stempel beim Übergang zu einer anderen Beutellänge ausgewechselt werden mußte, weil seine Länge der Länge des Beutels entsprechen mußte, um Mehrfachschweißungen der Beutellängsnaht zu vermeiden. However, impulse welding was disadvantageous in comparison to many known welding by heated rollers so far that they are not continuous Work allowed, as the punch changed when changing to a different bag length had to be, because its length had to correspond to the length of the bag, to allow multiple welds to avoid the longitudinal seam of the bag.
Der Erfinder hat sich die Aufgabe gestellt, diesen Nachteil der mit Impuls schweißung arbeitenden Maschine zur Herstellung gefüllter Beutel zu beheben. The inventor has set himself the task of eliminating this disadvantage with Impulse welding machine for producing filled bags to fix.
Die Lösung wurde darin gefunden, daß der Schweißstempel etwas länger ist als die zwischen zwei Schweißimpulsen abgezogene Schlauch- bzw. Folienlänge und daß er ferner, wie bekannt, quer zur Abzugsrichtung und auch - entgegen einer Rückstellkraft - in Abzugsrichtung beweglich ist, derart, daß er während der Schweißberührung der Azugsbewegung folgen kann.The solution was found in making the welding punch a little longer is the length of the hose or film drawn off between two welding pulses and that it also, as is known, transversely to the direction of withdrawal and also - against one Restoring force - is movable in the withdrawal direction, such that it occurs during welding contact can follow the pull movement.
Zweckmäßig sind beiderseits des Schweißstempels federnde Andrückglieder angebracht, welche einerseits für das Schweißen die Schlauchränder übereinanderhalten und die erwärmten Schweißstellen beim Abzug des Schlauches entlasten und über die andererseits der Schlauch beim Abzug den Schweißstempel während des Schweißimpulses mitnimmt. Resilient pressure members are expedient on both sides of the welding die attached, which on the one hand hold the hose edges one above the other for welding and relieve the heated welds when the hose is withdrawn and over the on the other hand, the hose when pulling off the welding stamp during the welding pulse takes away.
Vorteilhaft dient als Widerlager für den Schweiß- stempel eine am Einfüllrohr angeordnete Leiste, über die ein endloses, um Rollen innerhalb des Einfüllrohres gelenktes Band aus einem, wie bekannt, das Ankleben verhindernden Kunststoff, z. B. Polytetrafluoräthylen, geführt ist.Advantageously serves as an abutment for the welding stamp one on the filler tube arranged bar, over which an endless to roll within the filler pipe steered tape made of, as is known, the sticking preventing plastic, for. B. polytetrafluoroethylene is performed.
Zur jeweils rechtzeitigen Auslösung des Schweißimpulses kann zweckmäßigerweise die von der Vorratsrolle abgezogene Folie eine Meßrolle antreiben, die über einen Nocken den Impulsgeber betätigt. For the timely triggering of the welding pulse, it is advisable to the withdrawn from the supply roll film drive a measuring roller that has a Cam actuates the pulse generator.
In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Maschine dargestellt, und zwar zeigt Fig. 1 eine Seitenansicht der wesentlichen Teile, wobei der Stempel abgehoben ist, Fig. 2 einen teilweisen Querschnitt gemäß der Linie II-II der Fig. 1 in größerem Maßstabe, Fig. 3 denselben Querschnitt, jedoch gemäß der Linie II 1-111, wobei der Stempel in Arbeitsstellung sich befindet, Fig. 4 einen wenig vergrößerten Ausschnitt bzw. In the drawing is an embodiment of the invention Machine shown, namely Fig. 1 is a side view of the essentials Parts, wherein the punch is lifted off, Fig. 2 shows a partial cross-section according to the line II-II of FIG. 1 on a larger scale, FIG. 3 the same cross-section, however according to the line II 1-111, the punch is in the working position, Fig. 4 a slightly enlarged section or
Teilschnitt aus Fig. 1, wobei der Stempel sich ebenfalls in Arbeitsstellung befindet, Fig. 5 einen Querschnitt nach Linie V-V der Fig. 4.Partial section from Fig. 1, wherein the punch is also in the working position FIG. 5 shows a cross section along line V-V of FIG. 4.
Die Folie 1 läuft von der nicht gezeichneten Vorratsrolle aus zwischen den Rollen 2 und 3 hindurch und über die Umlenkrolle 4 zur Formschulter 5, von der sie mit Hilfe des Einfüllrohres 6 zu einem Schlauch 7 geformt wird, der dann auf dem Rohr 6 aufliegt. Die Rolle 3 dient als Meßrolle und ist mit einem Nocken 8 für die Zusammenarbeit mit dem Kontakt 9 für die Auslösung des Impulses zur Längsverschweißung des Schlauches verbunden. Die Abzugs-, Schweiß- und Schneidbacken 13 sind durch nicht gekennzeichnete Mittel zangenartig gegeneinander und um die einstellbare Beutellänge auf und ab bewegbar. The film 1 runs from the supply roll, not shown, between the rollers 2 and 3 through and over the pulley 4 to the forming shoulder 5, from the it is formed into a hose 7 with the help of the filler pipe 6, which then opens the tube 6 rests. The roller 3 serves as a measuring roller and is equipped with a cam 8 for the cooperation with the contact 9 for the triggering of the pulse for longitudinal welding of the hose connected. The trigger, welding and cutting jaws 13 are through unmarked means against each other like pliers and around the adjustable bag length movable up and down.
Ebenso wie das Einfüllrohr 6 ist der Träger 18 in dem nicht gezeichneten Maschinengestell gehalten. Just like the filler pipe 6, the carrier 18 is in the one not shown Machine frame held.
Am Träger 18 ist die Schiene 20 durch die Laschen 21 und 22 parallelogrammartig angelenkt und mittels eines Bolzens 19 in Richtung auf das Rohr 6 bewegbar. In der Schiene 20 ist der Schweißstempel 23 längsbeweglich geführt. In Ruhestellung wird der Schweißstempel 23 in seiner oberen Lage nach Fig. 1 gehalten. Am Stempel 23 sind federnde Halter 26 angelenkt, deren Aufgabe es ist, einerseits beim Schweißen die Ränder des Schlauches 7 übereinanderzuhalten und andererseits den Stempel 23 bei der Abzugsbewegung während der Schweißberührung mitzunehmen.On the carrier 18, the rail 20 is parallelogram-like due to the tabs 21 and 22 articulated and movable in the direction of the tube 6 by means of a bolt 19. In the Rail 20, the welding punch 23 is guided in a longitudinally movable manner. Will be in rest position the welding punch 23 is held in its upper position according to FIG. 1. On stamp 23 are resilient holders 26 articulated, the task of which is on the one hand during welding to hold the edges of the tube 7 one above the other and, on the other hand, the punch 23 to be taken along with the trigger movement during welding contact.
An den Enden eines Längsschlitzes des Einfüllrohres 6 sind zwei Walzen 31 und 32 lose drehbar gelagert. Über sie ist ein endloses Band 33 geführt, das aus einem das Ankleben verhindernden Stoff, z. B. Polytetrafluoräthylen, besteht. At the ends of a longitudinal slot of the filler pipe 6 are two rollers 31 and 32 loosely rotatably mounted. An endless belt 33 is passed over them, the from a sticking-preventing material, e.g. B. polytetrafluoroethylene exists.
Dabei läuft das Band 33 auf einer im Schlitz angeordneten Leiste 34. Zum Schutz des Bandes 33 gegen Staub od. ä. im Innern des Füllrohres 6 ist ein Abdeckblech 24 vorgesehen. The belt 33 runs on a bar arranged in the slot 34. To protect the belt 33 against dust od. Ä. Inside the filling tube 6 is a Cover plate 24 is provided.
Zur Erläuterung der Wirkungsweise sei von dem in Fig. 1 gezeigten Stadium ausgegangen. Die Backen 13 haben sich geschlossen und dabei den Schlauch 7 zusammengedrückt und quer verschweißt. Gleichzeitig wurde der vorher gefüllte und jetzt verschlossene Beutel abgeschnitten, der jedoch noch festgehalten wird. Dann wird in den Schlauch 7 oberhalb der Schweißstelle durch das Einfüllrohr 6 eine Portion des Füllgutes gefüllt. To explain the mode of operation, let us refer to that shown in FIG. 1 Stage run out. The jaws 13 have closed and thereby the hose 7 compressed and welded transversely. At the same time the one previously filled and now cut off the closed bag, which is still held in place. Then is in the hose 7 above the welding point through the filler pipe 6 a Portion of the product filled.
Anschließend bewegen sich die Backen 13 geschlossen um die Beutellänge nach unten und ziehen dabei den Schlauch 7 um diese Länge über das Rohr 6 ab. Die gleiche Länge der Folie 1 wird von der Vorratsrolle ab- und zwischen den Rollen 2 und 3 hindurchgezogen. Im Augenblick, wo der von der Rolle 3 angetriebene Nocken 8 den Kontakt 9 schließt, wird der Impuls für die Verschweißung der Schlauchlängsnaht ausgelöst. Der Stempel 23 wird beheizt, und der Bolzen 19 drückt den Stempel gegen den Schlauch 7 (s. Fig. 3 und 4). Zuvor kamen aber die Halter 26 auf dem Schlauch zur Anlage, um dessen Kanten in einer schweißgerechten Lage übereinanderzuhalten. Währenddessen wird durch die Berührung mit dem erhitzten Schweißstempel 23 die Längsnaht auf der Länge des Stempels 23 geschweißt, wobei die Leiste 34 als Widerlager für den Stempel 23 dient. Während der Abzugsbewegung des Schlauches gleitet dieser auf der Leiste 34 abwärts. The jaws 13 then move closed by the length of the bag downwards and pull the hose 7 by this length over the tube 6. the the same length of the film 1 is removed from the supply roll and between the rolls 2 and 3 pulled through. At the moment where the cam driven by the roller 3 8 the contact 9 closes, the impulse for the welding of the hose longitudinal seam triggered. The punch 23 is heated and the bolt 19 presses the punch against it the tube 7 (see FIGS. 3 and 4). Before that, however, the holders 26 came on the hose to the system in order to keep its edges one above the other in a position suitable for welding. Meanwhile, the contact with the heated welding die 23 causes the longitudinal seam welded along the length of the punch 23, the bar 34 as an abutment for the stamp 23 is used. During the withdrawal movement of the hose, it slides open the ledge 34 downwards.
Das mitlaufende Band 33 verhindert ein Ankleben der frischen Schweißnaht auf der Leiste 34. Dabei wird vor allem durch die Halter 26 der Stempel 23, solange die Schweißberälrung dauert, mitgenommen.The moving band 33 prevents the fresh weld seam from sticking on the bar 34. In this case, the holder 26 of the stamp 23, as long as the sweat lasts, taken away.
Nach Beendigung des Schweißimpulses wird die Schiene 20 mit dem Stempel 23 wieder abgehoben, und dieser kehrt in seine obere Ausgangsstellung in der Schiene 20 zurück. Der Schlauch 7 setzt darüber hinaus seine Abwärtsbewegung fort, bis die Backen 13 ihre unterste Lage entsprechend der eingestellten Beutellänge erreicht haben, aus der sie in bekannter Weise nach Freigabe des untersten Beutels in ihre Ausgangslage zurückkehren.After termination of the welding pulse, the rail 20 with the punch 23 lifted off again, and this returns to its upper starting position in the rail 20 back. The hose 7 also continues its downward movement until the Jaws 13 reached their lowest position according to the set bag length have from them in a known manner after releasing the bottom bag in their Return to the starting position.
Betont sei, daß der Schweißimpuls durch die Meßrolle 3 und die Kontakteinrichtung 8, 9 immer erst dann ausgelöst wird, wenn eine Folienlänge abgezogen ist, welche wenig kürzer als die Länge des Stempels 23 ist. Die Auslösung der Schweißung ist also unabhängig von der jeweils eingestellten Beutellänge. It should be emphasized that the welding pulse through the measuring roller 3 and the contact device 8, 9 is only triggered when a length of film has been removed, which is a little shorter than the length of the punch 23. The triggering of the weld is that is, regardless of the bag length set in each case.
