Die in den Zeichnungen dargestellte Vorrichtung 1 dient zum Füllen von flexiblen, flachen Verpackungsbeuteln 2 aus Kunststoffolie mit Esswaren, z.B. mit schüttfähigen Süssigkeiten. Mehrere Beutel 2 werden von einer nicht dargestellten, vorgeschalteten Herstellmaschine horizontal nebeneinanderliegend gleichzeitig taktweise angeliefert.The device 1 shown in the drawings is used to fill flexible, flat packaging bags 2 made of plastic film with edibles, for example with pourable ones Sweets. A plurality of bags 2 are delivered by an upstream manufacturing machine, not shown, horizontally next to one another at the same time in cycles.

Die Vorrichtung hat je zwei auf gemeinsamen Wellen 6 montierte hintere und vordere Kettenräder 3, 4, auf denen zwei parallele Ketten 5 kontinuierlich umlaufen. Die beiden Ketten 5 bestehen aus Kettengliedern 7 und gemeinsamen Achsen 8, um welche die Glieder 7 schwenkbar sind. Die Achsen 8 erstrecken sich quer zwischen den Ketten 5 senkrecht zur Transportrichtung A. Auf je zwei benachbarten Achsen 8 sind nach aussen abstehende Halter 9 mit je zwei Platten 10 montiert. Von der Vielzahl von Haltern 9 sind in Fig. 1 der besseren Uebersicht wegen nur fünf dargestellt. Eine der Wellen 6 ist durch einen Motor 11 angetrieben.The device has two rear and front sprockets 3, 4 mounted on common shafts 6, on which two parallel chains 5 continuously rotate. The two chains 5 consist of chain links 7 and common axes 8, about which the links 7 are pivotable. The axes 8 extend transversely between the chains 5 perpendicular to the direction of transport A. Holders 9 with two plates 10 each projecting outwards are mounted on two adjacent axes 8. Of the large number of holders 9, only five are shown in FIG. 1 for the better overview. One of the shafts 6 is driven by a motor 11.

Annähernd in der Horizontalebene der Achsen der Wellen 6 ist bei den Kettenrädern 3 eine Beschickungsstation 13 angeordnet, in welcher die Beutel 2 in die geöffneten Halter 9 eingeschoben werden. Ueber dem oberen, horizontalen Trum 12 der Ketten 5 sind eine Füllstation 14, eine Glättstation 15 und eine Siegelstation 16 vorhanden. Eine Entladestation 17 befindet sich schliesslich bei den Kettenrädern 4, wo die gefüllten und versiegelten Beutel z.B. auf ein Förderband 18 entladen werden. Die Füllstation 14 besteht aus mehreren nebeneinander angeordneten Einfülltrichtern 21, die beim Befüllen der Beutel mit den Ketten 5 mitbewegt werden. Dazu ist nur andeutungsweise als Beispiel eine um zwei Kettenräder 22 mit den Ketten 5 synchron umlaufende Kette 23 gezeigt, an welcher die Trichter 21 befestigt sind, sowie eine Parallelogrammführung 24. Vor den Trichtern 21 sind nicht dargestellte Dosiereinheiten angeordnet, falls die Beutel mit Schüttgut gefüllt werden sollen. Die Siegelbacken 26 der Siegelstation 16 laufen während des Siegelvorgangs in gleicher Weise mit den Ketten 5 mit. Die Glättstation 15 wird im wesentlichen durch ein schwenkbares Strichblech 25 gebildet.Approximately in the horizontal plane of the axes of the shafts 6, a loading station 13 is arranged in the chain wheels 3, in which the bags 2 are inserted into the opened holders 9. Above the upper, horizontal run 12 of the chains 5 there are a filling station 14, a smoothing station 15 and a sealing station 16. An unloading station 17 is finally located at the chain wheels 4, where the filled and sealed bags are unloaded, for example on a conveyor belt 18. The filling station 14 consists of several filling funnels arranged side by side 21, which are moved when filling the bag with the chains 5. For this purpose, a chain 23, synchronously rotating around two sprockets 22 with the chains 5, to which the funnels 21 are attached, and a parallelogram guide 24 are shown only as an example, and dosing units (not shown) are arranged in front of the funnels 21 if the bags are filled with bulk material should be. The sealing jaws 26 of the sealing station 16 run in the same way with the chains 5 during the sealing process. The smoothing station 15 is essentially formed by a pivotable reticle 25.

Wie insbesondere aus Fig. 3 und 4 ersichtlich ist, sind auf den Achsen 8 Träger 30 festgeschraubt. Die Platten 10 sind an diesen Trägern 30 leicht auswechselbar befestigt, damit die Umstellung der Vorrichtung 1 auf andere Beutelformate einfach und rasch durchgeführt werden kann. Dazu sind an den Platten 10 Bolzen 31 angenietet. Auf diese Bolzen 31 sind federbelastete Hülsen 32 mit einem konischen Flansch 33 aufgesetzt. Die Hülse 32 greift in einen Schlitz 34, der Flansch 33 in eine konische Ansenkung 35 des Trägers 30 ein.As can be seen in particular from FIGS. 3 and 4, 8 carriers 30 are screwed onto the axes. The plates 10 are fastened to these supports 30 in an easily replaceable manner, so that the changeover of the device 1 to other bag formats can be carried out simply and quickly. For this purpose, 10 bolts 31 are riveted to the plates. Spring-loaded sleeves 32 with a conical flange 33 are placed on these bolts 31. The sleeve 32 engages in a slot 34, the flange 33 in a conical countersink 35 of the carrier 30.

In Fig. 5 und 6 ist das Getriebe zum Oeffnen und Schliessen der Halter 9 schematisch gezeigt. Die beiden zueinandergehörenden Achsen 8 sind durch Zahnsegmente 36 gegenläufig miteinander gekoppelt. Auf der einen dieser Achsen 8 sitzt aussen ein Hebel 37 mit einer Rolle 38, die in einer Führungskurve 39 läuft.5 and 6, the transmission for opening and closing the holder 9 is shown schematically. The two axes 8 belonging to one another are opposed by toothed segments 36 coupled with each other. A lever 37 with a roller 38, which runs in a guide curve 39, sits on the outside of one of these axes 8.

Wie aus Fig. 3 und 4 hervorgeht, sind die beiden zusammengehörenden Achsen 8 durch mehrere Laschen 45 miteinander verbunden. Auf diesen Laschen 45 ist eine durchgehende erste Klemmbacke 44 benachbart der vorderen Achse 8 mit Schrauben 46 befestigt. Auf der hinteren Achse 8 sind mehrere zweite Klemmbacken 47 schwenkbar gelagert. Mit diesen Backen 47 ist ein Arm 48 verbunden. Die Welle 6 der Kettenräder 3 ist in einem stationären Rohr 50 drehbar gelagert. Am Rohr 50 sind mehrere Arme 51 angeschweisst, die am freien Ende Rollen 52 tragen. Unmittelbar vor der Beschickungsstation 13 laufen die Arme 48 auf den Rollen 52 auf und heben die Backen 47 von der Backe 44 ab, so dass der versiegelte Vorderrand der Beutel 2 zwischen die Backen 44, 47 eingeschoben werden kann. Beim Verlassen der Beschickungsstation 9 schliessen die Backen 44, 47 durch die Kraft je einer Feder 49 und klemmen die Beutel 2 an dem der Einfüllöffnung gegenüberliegenden Rand.As can be seen from FIGS. 3 and 4, the two axes 8 belonging together are connected to one another by a plurality of tabs 45. On these tabs 45, a continuous first jaw 44 is attached adjacent to the front axis 8 with screws 46. A plurality of second clamping jaws 47 are pivotably mounted on the rear axle 8. An arm 48 is connected to these jaws 47. The shaft 6 of the chain wheels 3 is rotatably supported in a stationary tube 50. A plurality of arms 51 are welded to the tube 50 and carry rollers 52 at the free end. Immediately before the loading station 13, the arms 48 run on the rollers 52 and lift the jaws 47 from the jaw 44, so that the sealed front edge of the bags 2 can be inserted between the jaws 44, 47. When leaving the loading station 9, the jaws 44, 47 close by the force of one spring 49 each and clamp the bags 2 on the edge opposite the filling opening.

Die Führungskurve 39 ist so ausgelegt, dass die beiden Platten 10 der Halter 9 zwischen der Beschickungsstation 13 und der Füllstation 14 leicht geschlossen werden. Um die Beutel 2 bei der Füllstation 14 optimal geöffnet zu halten, kann es zweckmässig sein, bei jeder der mehreren seitlich nebeneinander laufenden Beutelreihen oben ausserhalb des freien Endes der Platten 10 zwei seitliche Führungsbleche anzubringen, die gegen die Füllstation 14 hin leicht konvergieren. Nach dem Befüllen werden die Halter 9 durch die Führungskurve 39 langsam geschlossen, damit ein Ausblasen leichter Bestandteile aus den gefüllten Beuteln vermieden wird.The guide curve 39 is designed such that the two plates 10 of the holders 9 between the loading station 13 and the filling station 14 are closed slightly. In order to keep the bags 2 optimally open at the filling station 14, it may be expedient to attach two lateral guide plates to each of the several rows of bags running side by side at the top outside the free end of the plates 10 and which converge slightly towards the filling station 14. After filling, the holders 9 are slowly closed by the guide curve 39 so that light components are not blown out of the filled bags.

Um eine einwandfreie Siegelnaht ohne Falten zu erreichen, ist es zweckmässig, den über die Platten 10 vorstehenden Rand 56 der Beutel 2 vor der Siegelstation 16 glattzustreichen. Dazu dient das Streichblech 25 (Fig. 7), das um eine Achse 57 mittels eines Pneumatikzylinders 58 hin und her schwenkt und bei dieser Schwenkbewegung den Rand 56 der Beutel um die Ränder der Platten 10 schwenkt.In order to achieve a perfect sealing seam without folds, it is expedient to smooth out the edge 56 of the bag 2 protruding beyond the plates 10 in front of the sealing station 16. For this purpose, the mouldboard 25 (FIG. 7) is used, which pivots back and forth about an axis 57 by means of a pneumatic cylinder 58 and pivots the edge 56 of the bag around the edges of the plates 10 during this pivoting movement.

Bei der Entladestation 17 werden die Backen 44, 47 in gleicher Weise geöffnet, wie bei der Beschickungsstation 13. Ausserdem werden durch die Führungskurve 39 die beiden Platten 10 jedes Halters 9 auseinandergespreizt.In the unloading station 17, the jaws 44, 47 are opened in the same way as in the loading station 13. In addition, the guide plates 39 spread the two plates 10 of each holder 9 apart.

Die beschriebene Vorrichtung ist einfach und kompakt aufgebaut und deshalb preiswert herstellbar und leicht zu warten. Die Beutel 2 werden senkrecht zu ihrer Breitseite an der Füllstation 14 vorbeigeführt. Dadurch können sie sehr dicht aufeinanderfolgen. Dies ergibt eine kurze Bauweise. Ausserdem wird mit einer relativ geringen, gleichförmigen Umlaufgeschwindigkeit der Ketten 5 eine hohe Verpackungsleistung erzielt.The device described has a simple and compact structure and is therefore inexpensive to manufacture and easy to maintain. The bags 2 are guided past the filling station 14 perpendicular to their broad side. This allows them to do a lot follow closely. This results in a short construction. In addition, a high packaging performance is achieved with a relatively low, uniform rotational speed of the chains 5.

Die Beschickungsstation 13 kann abweichend vom dargestellten Ausführungsbeispiel auch weiter oben an den Kettenrädern 3 oder senkrecht von oben auf dem horizontalen Trum 12 angeordnet werden. In diesem Falle können die Klemmbacken 44, 47 und deren Betätigung auch weggelassen und z.B. durch eine U-förmige Schiene als Anschlag ersetzt werden. Je nach Art der Beschickung mit leeren Beuteln kann es auch zweckmässig sein, hinter der stationären Klemmbacke 44 einen stationären Anschlag vorzusehen. Weil die Füllstation 14, die Glättstation 15 und die Siegelstation 16 alle über dem horizontalen Trum 12 angeordnet sind, werden sie zweckmässig auf einem gemeinsamen, in der Höhe einstellbaren Träger montiert. Die Vorrichtung ist dann sehr rasch auf andere Beutelformate einstellbar, indem dieser Träger auf die passende Höhe eingestellt und die Platten 10 ausgetauscht werden.In contrast to the exemplary embodiment shown, the loading station 13 can also be arranged further up on the chain wheels 3 or vertically from above on the horizontal run 12. In this case the jaws 44, 47 and their actuation can also be omitted and e.g. can be replaced by a U-shaped rail as a stop. Depending on the type of loading with empty bags, it may also be expedient to provide a stationary stop behind the stationary jaw 44. Because the filling station 14, the smoothing station 15 and the sealing station 16 are all arranged above the horizontal run 12, they are expediently mounted on a common, height-adjustable support. The device can then be adjusted very quickly to other bag formats by setting this carrier to the appropriate height and exchanging the plates 10.

Die beiden Platten 10 jedes Halters 9 sind benachbart ihren freien Enden gegeneinander stumpfwinklig geknickt. Durch diese Massnahme wird beim Schliessen der Halter 9 gegen die Siegelstation 16 zu der freie Beutelrand 26 optimal für die Versiegelung vorbereitet. Weil die beiden Platten 10 jedes Halters 9 die ganzen Grossflächen des Beutels 2 abstützen, kann dieser optimal gefüllt werden. Dadurch kann der Verbrauch an Verpackungsmaterial für einen gegebenen Beutelinhalt minimiert werden.The two plates 10 of each holder 9 are bent at an obtuse angle adjacent to their free ends. By this measure, when the holder 9 is closed against the sealing station 16, the free bag edge 26 is optimal for the Seal prepared. Because the two plates 10 of each holder 9 support the entire large areas of the bag 2, it can be optimally filled. As a result, the consumption of packaging material for a given bag content can be minimized.
