Description

Automatische Verpackungsmaschine zum Herstellen schlauchförmiger Packungen Automatische Verpackungsmaschinen für Waren und Gebrauchsgegenstände sind bekannt. Bei solchen Verpackungsmaschinen werden die zu verpackenden Waren oder Gegenstände bestimmter Form automatisch in eine Reihe von geformten Verpackungen gefüllt. Die Maschinen bilden die Verpackungen aus einem Streifen eines geeigneten biegsamen Materials, vorzugsweise einem thermoplastischen Film, wobei der Boden jedes Beutels oder jeder Verpackung verschlossen wird, während diese noch mit dem Streifen verbunden sind, um ein Auslaufen des eingefüllten Erzeugnisses zu verhindern. Der Beutel oder die Verpackung, die in der Maschine einen Längsverschluß erhält, wird dann an ihrem oberen Ende verschlossen, vom Verpackungsmaterialstreifen abgetrennt und aus der Maschine ausgetragen. Die Verpackung wird schließlich vollständig versiegelt.Automatic packaging machine for the production of tubular packs Automatic packaging machines for goods and utensils are known. In such packaging machines, the goods or objects to be packed certain shape automatically filled into a series of shaped packages. the Machines form the packaging from a strip of suitable flexible material Material, preferably a thermoplastic film, the bottom of each bag or each package is sealed while it is still attached to the strip to prevent leakage of the filled product. The bag or the packaging, which is longitudinally sealed in the machine, is then attached to its closed at the top, separated from the packaging material strip and removed from the Machine discharged. The packaging is finally completely sealed.

Die verschiedenen Arten solcher Maschinen haben gewisse Nachteile. Viele der bekannten Maschinen arbeiten mit quer verschließenden Schweißbacken, die absatzweise an dem Verpackungsfilm ziehen und ihn so vorwärts bringen, wodurcch die Leistung der Maschine begrenzt ist. The various types of such machines have certain disadvantages. Many of the known machines work with cross-sealing welding jaws that Pull on the packaging film in sections and bring it forward wherever you want the performance of the machine is limited.

Es ist auch bereits eine Vorrichtung bekannt, bei der ein Verpackungsschlauch gebildet und kontinuierlich weiterbewegt wird, wobei in einer Führung angeordnete Schweiß- und Schneideinrichtungen vorgesehen sind, die hin und her bewegt werden und während des Schweißens mitlaufen. Hierbei erfolgt die Hin- und Herbewegung der Schweiß- und Schneideinrichtungen durch einen Nockenantrieb. Es sind zwei miteinander gekuppelte Wellen vorgesehen, auf denen Nocken sitzen, und einer der Nocken dient zur Bewegung eines zweiarmigen Hebels, der für die waagerechte Verschiebung eines Schlittens sorgt, an dem ein Teil der Schweißeinrichtung befestigt ist. A device is also already known in which a packaging tube is formed and continuously moved on, being arranged in a guide Welding and cutting devices are provided, which are moved back and forth and run along while welding. Here the back and forth movement takes place Welding and cutting devices by a cam drive. It's two together coupled shafts are provided on which cams sit, and one of the cams is used for moving a two-armed lever, which is used for the horizontal displacement of a Provides carriage to which part of the welding device is attached.

Dieser Schlitten führt außerdem eine Vertikalbewegung durch, um das obere Schweißorgan abheben und zurückbefördem zu können, wenn es während seiner Horizontalverschiebung in eine Endstellung gelangt ist. Zur Vertikalverschiebung wird dabei der andere Nocken verwendet, der über einen schwenkbaren Hebel auf den erwähnten Schlitten einwirkt.This carriage also performs a vertical movement to move the to be able to lift off the upper sweat organ and transport it back if it is during his Horizontal shift has reached an end position. For vertical displacement the other cam is used, which has a pivoting lever on the mentioned slide acts.

Diese bekannte Vorrichtung weist einen verhältnismäßig komplizierten Aufbau auf, und es wird auch eine verhältnismäßig verwickelte Bewegung der Teile angewendet, so daß nicht nur ein großer Aufwand getrieben werden muß, um eine solche Maschine herzustellen, sondern auch die Gefahr einer häufigen Betriebsstörung nicht vernachlässigt werden kann. This known device has a relatively complicated Build up, and there will also be a relatively intricate movement of the parts applied, so that not only a great effort must be made to such Machine, but also the risk of frequent malfunctions can be neglected.

Der Erfindung liegt die Aufgabe zugrunde, die erwähnten Nachteile der bekannten Verpackungs- maschinen zu vermeiden und vor allem eine Maschine zu schaffen, die wesentlich weniger aufwendig gebaut ist und eine erheblich größere Betriebssicherheit verspricht. Als Ausgangspunkt dient dabei eine automatische Verpackungsmaschine zum Herstellen versiegelter Packungen aus einem kontinuierlich zugeführten Film aus thermoplastischem Material, das von einer Vorratsrolle einem Formrohr zugeführt, zu einem Schlauch geformt und kontinuierlich am Formrohr entlanggeschoben wird, wobei federnd abgestützte Schweißbacken unterhalb des Formrohres den Schlauch während seiner Abwärtsbewegung quer zu seiner Längsachse zusammenpressen und verschweißen. The invention is based on the mentioned disadvantages the well-known packaging avoid machines and especially a machine too create that is built much less expensively and a considerably larger one Operational reliability promises. An automatic packaging machine serves as the starting point for producing sealed packages from a continuously fed film made of thermoplastic material, which is fed from a supply roll to a molding tube, is shaped into a tube and pushed continuously along the shaped tube, resiliently supported welding jaws below the shaped tube during the hose compress and weld its downward movement transversely to its longitudinal axis.

Nach der Erfindung kennzeichnet sich die Verpackungsmaschine durch die Kombination folgender, teilweise an sich bekannter Merkmale: a) auf zwei gegensinnig bewegten Kurbeln von gleichem Radius, die gleichzeitig ihre obersten und untersten Stellungen durchlaufen, ist je eine Schweißbacke federnd gelagert, die demnach eine Kreisbewegung vollführt und mittels eines auf dem anderen Kurbelzapfen gleitenden, geschlitzten Führungsgliedes bei der Kreisbewegung stets waagerecht gehalten wird, wobei der Kurbelradius so groß gewählt ist, daß die abwärts gerichtete Vertikalbewegung der Schweißbacken vom Augenblick der Berührung des Schlauchs bis zum Abheben praktisch vollkommen mit der Schlauchbewegung übereinstimmt; b) ein in einem waagerechten Schlitz der einen Schweißbacke angeordnetes Messer, das zum Abtrennen der verschweißten Einzelpackungen dient, ragt in einem waagerechten Schlitz der anderen Schweißbacke hinein, wenn die Kurbeln einander in ihrer innersten Stellung genau gegenüberstehen; c) dem Antrieb der Kurbeln ist eine Photozelle zugeordnet, die auf dem Verpackungsfilm befindliche Markierungen abtastet. According to the invention, the packaging machine is characterized by the combination of the following features, some of which are known per se: a) on two in opposite directions moving cranks of the same radius, which are their top and bottom at the same time Pass through positions, a welding jaw is resiliently mounted, which is therefore one Performs a circular movement and by means of a sliding on the other crank pin, slotted guide link is always held horizontally during the circular movement, wherein the crank radius is chosen so large that the downward vertical movement the welding jaws practical from the moment the hose is touched until it is lifted off perfectly coincides with the movement of the hose; b) one in a horizontal Slot of the one welding jaw arranged knife, which is used to cut the welded Single packs serves, protrudes in a horizontal slot of the other Weld jaw into it when the cranks exactly meet each other in their innermost position face; c) a photocell is assigned to the drive of the cranks scans marks on the packaging film.

Hierzu sei bemerkt, daß es bereits bekannt ist, die Schweißbacken bei einer solchen Verpackungsmaschine durch gegenläufige Kurbeln in der Schließ-und Öffnungsrichtung anzutreiben. Dabei greifen die Kurbeln in senkrechte Schlitze der Schweißbackenträger ein, und letztere werden in einer feststehenden Führung hin und her bewegt. Das bedingt, daß der geformte Schlauch im Augenblick der Schweißung stillsteht. Bei der Erfindung dagegen wird der Schlauch kontinuierlich fortbewegt, und die Schweißbacken führen ihre Tätigkeit während der Schlauchbewegung aus. Die Mitbewegung der Schweißbacken wird dadurch erreicht, daß die Führungen für die Schweißbacken von den Kurbelzapfen der Kurbeln getragen werden und demzufolge eine Auf- und Abwärtsbewegung durchführen, während die Schweißbacken in den auf- und abwärts bewegten Führungen ihre Öffnungs- bzw. Schließbewegung ausführen. It should be noted that the welding jaws are already known in such a packaging machine by counter-rotating cranks in the closing and closing Drive opening direction. The cranks grip the vertical slots of the Welding jaw carrier a, and the latter are in a fixed guide and moved here. This means that the formed hose must be welded at the moment stands still. In the invention, however, the hose is moved continuously, and the welding jaws perform their work during the hose movement. the Movement of the welding jaws is achieved in that the guides for the welding jaws are carried by the crank pins of the cranks and consequently an up and down movement perform while the welding jaws in the guides moving up and down execute their opening or closing movement.

Bei der Erfindung wird nun von der Erkenntnis Gebrauch gemacht, daß eine für die Praxis vollkommen ausreichende Übereinstimmung zwischen der an sich sinusförmig veränderlichen Kurbelzapfenbewegung und der linearen Schlauchbewegung vorliegt, wenn man den Kurbelradius im Verhältnis zum Abstand zwischen Kurbeldrehachse und Schlauchmittellinie geeignet wählt. Dann kommen die Schweißbacken mit derSchlauchoberfläche nur während eines Weges in Berührung, auf dem die Kurbelzapfengeschwindigkeit nahezu konstant ist. In the invention, use is now made of the knowledge that a correspondence between the per se, which is perfectly adequate for practice sinusoidally variable crank pin movement and the linear hose movement exists when the crank radius is in relation to the distance between the crank axis of rotation and choose the hose center line appropriately. Then come the welding jaws with the hose surface in contact only during a path where the crank pin speed is close to is constant.

Es ist auch an sich bereits bekannt, zum Abtrennen der verschweißten Packungen ein in der einen Schweißbacke angeordnetes und in ihr verschiebbares Messer zu verwenden. It is also already known per se, for separating the welded Packs a knife arranged in one welding jaw and displaceable in it to use.

Eine Verpackungsmaschine mit den obenerwähnten Merkmalen ist nicht nur besonders leistungsfähig, kann also mit hoher Geschwindigkeit betrieben werden, sondern läßt sich auch durch die Anwendung der photoelektrischen Steuerung bequem auf verschiedene Erzeugnisse umstellen. Vorteilhaft ist bei ihr ferner, daß übliche Zuführvorrichtungen, die nach Volumen oder Nettogewicht oder zählend zuteilen, verwendet werden können. Sie ist verhältnismäßig klein und stabil, eignet sich für Erzeugnisse verschiedener Art und liefert in schneller Folge genau gefüllte und verschlossene Beutel oder Verpackungen mit einem bestimmten Wareninhalt. A packaging machine with the features mentioned above is not only particularly powerful, so can be operated at high speed, but can also be conveniently carried out using photoelectric control switch to different products. It is also advantageous that the usual Feeders that dispense by volume or net weight or by counting are used can be. It is relatively small and stable, suitable for products of various types and delivers precisely filled and sealed ones in quick succession Bags or packaging with a specific product content.

Das Gestell 17 der Maschine hat an seinem oberen Teil ein Paar aufwärts gerichteter abgewinkelter Arme 18. An den oberen Enden dieser Arme 18 sind Lager für eine Welle 19 vorgesehen, die eine Vorratsrolle 20 mit Verpackungsmaterial trägt. Das Material rollt nach unten in Gestalt des Verpackungsfilms 20' ab, der über mehrere Führungsrollen 21 und 22 und über einen Faltsteg an eine Formröhre 16 geführt und von dieser gefaltet und schlauchförmig geformt wird, wie es bei automatischen Verpackungsmaschinen für Schläuche aus biegsamem Material üblich ist. The frame 17 of the machine has a pair on its upper part directed angled arms 18. At the upper ends of these arms 18 are bearings provided for a shaft 19 which carries a supply roll 20 with packaging material. The material rolls down in the form of the packaging film 20 ', which over several Guide rollers 21 and 22 and guided via a folding web to a shaped tube 16 and is folded by this and formed into a tubular shape, as is the case with automatic packaging machines is common for hoses made of flexible material.

Nach den Fig. 1, 2, 3 der Zeichnung wird die ganze Vorrichtung von einem Elektromotor 24 angetrieben, auf dessen Abtriebswelle 25 ein Kettenrad 26 für eine endlose Kette 27 sitzt. In dem unteren Maschinengestell 17 ist waagerecht eine Schweißbackenantriebswelle 28 vorgesehen, die an ihrem äußeren Ende eine elektrische Schaltkupplung29 trägt. Auf einem Wellenteil 30, der mit der Schaltkupplung 29 verbunden ist, sind im Abstand Kettenräder 31 und 32 befestigt. Das Kettenrad 32 wird von der endlosen Kette 27 angetrieben, das Rad 31 auf der Welle 30 treibt über die endlose Kette 33 ein Ketten rad 34, das fest auf einer Welle 35 angebracht ist. Eine Welle 36 einer Filmvorschubrolle 44 ist mit einem Kettenrad 37 versehen, das von einem Kettenrad 39 der Welle 35 über eine Kette 38 angetrieben wird (F i g. 1 und 3). According to FIGS. 1, 2, 3 of the drawing, the whole device is of driven by an electric motor 24, on whose output shaft 25 a sprocket 26 for an endless chain 27 is seated. In the lower machine frame 17 is horizontal a welding jaw drive shaft 28 is provided which at its outer end has an electric Clutch29 carries. On a shaft part 30 which is connected to the clutch 29 is, chain wheels 31 and 32 are attached at a distance. The sprocket 32 is of driven by the endless chain 27, the wheel 31 on the shaft 30 drives over the endless Chain 33 a chain wheel 34 which is fixedly mounted on a shaft 35. A wave 36 of a film feed roller 44 is provided with a sprocket 37 which is of a The sprocket 39 of the shaft 35 is driven via a chain 38 (FIGS. 1 and 3).

Auf der Welle 35 ist ein Zahnrad 40 befestigt, das mit einem Zahnrad 41 auf einer Schweißradwelle 42 kämmt, auf der ein Längsnahtschweißrad 43 (F i g. 3) angebracht ist, das in einem geheizten Gehäuse untergebracht ist.On the shaft 35 a gear 40 is attached, which with a gear 41 meshes with a welding wheel shaft 42 on which a longitudinal seam welding wheel 43 (FIG. 3) is attached, which is housed in a heated housing.

Durch den beschriebenen Antrieb wird von dem Motor 24 die Welle 36 mit der Filmvorschubrolle 44 vorzugsweise aus Gummi oder einem anderen elastischen Material bestehend, angetrieben. Wenn die Maschine in Betrieb ist, ist die ununterbrochen angetriebene Vorschubrolle 44 mit dem Verpackungsfilm 20' im Eingriff und schiebt ihn entlang dem Formrohr 16 zu den Verschließbacken nach unten. The shaft 36 of the motor 24 is driven by the drive described with the film advance roller 44 preferably made of rubber or some other elastic material consisting, driven. When the machine is in operation, it is uninterrupted driven feed roller 44 engages the wrapping film 20 'and pushes down along the forming tube 16 to the closing jaws.

Die Schließvorrichtung ist in Einzelheiten in der perspektivischen Ansicht der Fig.5 und in 4 gezeigt. The locking device is shown in detail in the perspective View of FIG. 5 and shown in FIG.

An Druckkörpern 45 sind Schweißbacken 46 durch Stiftschrauben 47 federnd abgestützt. Eine der Schweißbacken trägt ein Messer 48, das in Schlitze 49 der beiden Schweißbacken ragt, so daß es quer zum Filmmaterial vorgeschoben werden kann, um aneinandergrenzende Verpackungen zu trennen. Die Druckkörper sind zwischen waagerechten parallelen Führungsgliedern 50 mit Führungsschlitzen 51 angeordnet und je an einem Schlitten befestigt. In jedem Druckkörper 45 ist ein Kurbelzapfen 52 gelagert, der an einem Ende durch den Führungsschlitz 51 des einen Führungsgliedes oder Schlittens hindurchragt, während er am anderen Ende in dem anderen Schlitten gelagert ist. Welding jaws 46 are attached to pressure bodies 45 by means of studs 47 resiliently supported. One of the welding jaws carries a knife 48 which slits 49 of the two welding jaws protrudes so that it can be advanced across the film material can be used to separate adjacent packaging. The pressure hulls are between horizontal parallel guide members 50 with guide slots 51 are arranged and each attached to a slide. In each pressure body 45 there is a crank pin 52 stored, which at one end through the guide slot 51 of the one guide member or slide protrudes through it, while it is at the other end in the other slide is stored.

Eine Kurbelkröpfung 52 ist mit der Welle 28 verbunden. Fest auf der Welle 28 ist ein Zahnrad befestigt, das über Zahnräder 54 und 55 ein Zahnrad 56 auf einer Welle 57 antreibt, die mit der anderen Kurbelkröpfung 52 (s. F i g. 5) verbunden ist. Die beiden Kurbeln 52 erhalten also ihre Bewegung von der Welle 28 und bewegen die Schweißvorrichtung nach F i g. 5 auf- und abwärts und verschieben gleichzeitig die Druckkörper 45 mit den Schweißbacken horizontal aufeinander zu und voneinander weg, geführt durch die Schlitze 51 in den Führungsgliedern 50. Die den Druckkörpern erteilte Bewegung ist derart, daß während eines Umlaufs der Welle 28 die Schweißbacken in der in F i g. 7 gestrichelten Stellung zusammentreffen, in der sie das dazwischenliegende Verpackungsmaterial zusammendrücken, das den Boden des einen Beutels und den oberen Teil des darunterliegenden Beutels bildet. Dann bewegen sich die Schweißbacken senkrecht abwärts in die in vollen Linien gezeigte Stellung und noch darunter. Während dieser Zeit werden die federbelasteten Backen zurückgedrückt und das Messer 48 durch das Verpakkungsmaterial gestoßen, um einen fertigen Beutel abzutrennen. Die Schweißbacken 46 werden wie üblich elektrisch und von einem Thermostaten gesteuert beheizt. Die Stromzuführung geschieht durch ein Kabel 58. A crank offset 52 is connected to the shaft 28. Fixed on the A gearwheel is attached to shaft 28, and a gearwheel 56 via gears 54 and 55 drives on a shaft 57, which with the other crank crank 52 (see Fig. 5) connected is. The two cranks 52 therefore receive their movement from the shaft 28 and move the welding device according to FIG. 5 up and down and move at the same time the pressure body 45 with the welding jaws horizontally towards one another and away from each other, guided by the slots 51 in the guide members 50. The The movement imparted to the pressure bodies is such that during one revolution of the shaft 28 the welding jaws in the FIG. 7 dashed position meet, in which they compress the packaging material in between that forms the bottom of one pouch and the upper part of the underlying pouch. then the welding jaws move vertically downwards into the one shown in full lines Position and even below. During this time, the spring-loaded jaws pushed back and the knife 48 pushed through the packaging material to a cut off the finished bag. The welding jaws 46 are electrical and as usual heated controlled by a thermostat. Power is supplied through a Cable 58.

Wenn der Motor in Betrieb ist, wird durch den vorher beschriebenen Antriebsmechanismus die Filmvorschubrolle 44 beständig mit einer gleichbleibenden Geschwindigkeit angetrieben und schiebt das Verpackungsmaterial 20' abwärts entlang der Formröhre 16 zur Schweißvorrichtung. When the engine is running, it is indicated by the previously described Drive mechanism the film advance roller 44 steadily with a constant Speed driven and pushes the packaging material down 20 ' the forming tube 16 to the welding device.

Die Vorrichtung wird vorzugsweise mit einer photoelektrischen Zelle 59 ausgerüstet, deren Strahl durch eine Markierung auf dem Verpackungsfilm 20' unterbrochen wird (s. Fig. 11). Die Betätigung der photoelektrischen Zelle 59 durch die Markierung 60 auf dem Verpackungsfilm 20' setzt ein Relais 61 unter Strom, das die Kupplung 29 betätigt und damit durch den vorher beschriebenen Mechanismus den Kreislauf der Schweißvorrichtung nach F 1 g. 5 auslöst. The device is preferably made with a photoelectric cell 59 equipped, the beam of which is interrupted by a marking on the packaging film 20 ' (see Fig. 11). The actuation of the photoelectric cell 59 by the marker 60 on the packaging film 20 'energizes a relay 61 which the clutch 29 actuated and thus the circuit of the Welding device according to F 1 g. 5 triggers.

Die Länge der Beutel wird durch die Wirkung der photoelektrischen Zelle und der Markierungen auf dem Verpackungsfilm bestimmt. Die senkrechte Geschwindigkeit der aneinanderliegenden Schweißbak- ken 46 stimmt mit der Umfangsgeschwindigkeit der Filmzuführrollen 44 überein. The length of the bag is determined by the action of the photoelectric Cell and the markings on the packaging film. The vertical speed of the adjacent welding jaws ken 46 agrees with the peripheral speed of the film feed rollers 44 match.

In F i g. 4 ist ein gefüllter fertiger Beutel 63 von dem darüberliegenden Beutel 62 getrennt. Der um die Formröhre 16 gelegte Verpackungsfilm muß zusätzlich zu der vorher beschriebenen Verschweißung längsverschweißt werden. Eine Einrichtung zum Längsverschweißen ist in Fig. 8 dargestellt, wobei die Ränder des um die Formröhre 16 dirigierten Verpackungsfilms sich überlappen, mit dem beheizten Antriebsrad 43 in Eingriff kommen und so längsverschweißt werden. In Fig. 9 ist eine geänderte Ausführungsform zur Bildung der Längsschweißung dargestellt, wobei die Ränder des um die Formröhre 16 gelagerten Verpackungsfilms in Form eines Grates zusammenstoßen und der Grat durch ein Paar beheizter Treibrollen 43' läuft. In Fig. 4 is a filled finished bag 63 from the overlying one Bag 62 separated. The wrapping film placed around the forming tube 16 must additionally are longitudinally welded to the previously described weld. An institution for longitudinal welding is shown in Fig. 8, the edges of the around the forming tube 16 directed packaging film overlap with the heated drive wheel 43 come into engagement and are thus longitudinally welded. In Fig. 9 is a modified one Embodiment shown for the formation of the longitudinal weld, the edges of the around the forming tube 16 stored packaging film collide in the form of a ridge and the ridge passes through a pair of heated pinch rollers 43 '.

Bei den üblichen automatischen Verpackungsmaschinen bewirken die den Verpackungsflansch zusammendrückenden Schweißbacken den Vorschub desselben über eine bestimmte Länge. Der Vorschub bestimmt die Länge der Verpackung. Wenn die Länge geändert werden soll, muß die Maschine neu eingerichtet werden, um einen anderen Vorschub durch die Schweißbacken zu erhalten. In conventional automatic packaging machines, the the welding jaws compressing the packaging flange over the advance of the same a certain length. The feed determines the length of the packaging. If the length to be changed, the machine must be set up again to accommodate a different one To get feed through the welding jaws.

Im Gegensatz zu diesen üblichen automatischen Verpackungsmaschinen wird die Länge der Verpakkung bei der Maschine der Erfindung, in welcher der Verpackungsfilm kontinuierlich weitergeführt wird, einzig durch die Zeitfolge des Einschaltens des Arbeitstaktes der Verschweißeinrichtung zum Herstellen des Verschlusses und zum Abtrennen der Verpackungen bestimmt, wobei dieses Einschalten in bekannter Weise durch eine photoelektrische Zelle von in Abständen auf dem Verpackungsfilm angebrachten Markierungen her gesteuert wird. Infolgedessen ist es bei der Vorrichtung nach der Erfindung, wenn die Länge der Beutel oder Verpackungen geändert werden soll, nur nötig, die Filmrolle auf der Welle 19 gegen eine Rolle mit anderen Markierungsabständen auszuwechseln, die über die photoelektrische Zelle einen anderen Takt des Einschaltens des Schweißbackenantriebes und damit eine andere Länge der Verpackungen verursachen, ohne daß der Umbau irgendeines Teiles der Verpackungsmaschine nötig wird. In contrast to these usual automatic packaging machines becomes the length of the package in the machine of the invention in which the packaging film is continued continuously, solely by the time sequence in which the Work cycle of the welding device for producing the closure and for Separating the packaging determined, this switching on in a known manner by a photoelectric cell of spaced apart on the packaging film Markings is controlled here. As a result, it is in the device according to the Invention, when the length of the bags or packaging needs to be changed, only necessary, the film roll on the shaft 19 against a roll with different marking distances to replace the one via the photoelectric cell a different cycle of switching on cause of the sealing jaw drive and thus a different length of the packaging, without the need to convert any part of the packaging machine.

Dank des kontinuierlichen Vorschubes durch die Vorschubrollen 44, die den Verpackungsfilm vorschieben, liegt die Geschwindigkeit der Maschine nach der Erfindung weit über der Geschwindigkeit der üblichen automatischen Verpackungsmaschinen, die den Verpackungsfilm absatzweise durch den von den Schweißbacken ausgeübten Zug vorschieben und demzufolge auch eine große Bauhöhe erfordern, die durch den Vorschubweg der Schweißbacken erforderlich wird. Thanks to the continuous feed by the feed rollers 44, that advance the packaging film, the speed of the machine is behind of the invention far above the speed of conventional automatic packaging machines, the wrapping film intermittently by the tension exerted by the sealing jaws advance and therefore also require a large overall height, which is due to the feed path the welding jaw is required.
