Abstract

The tube and bag making machine (10) has a tube forming device (11), consisting of a shaping shoulder (14) and a shaping tube (15). This device forms a tube (12) from a continuously-fed endless heat-sealing packing strip (13). The longitudinal seam sealing device (25) is in the form of two heated welding belts running opposite each other. They are continuously driven and run at the same speed as the tube. The seam thus runs at the same speed as the tube, avoiding sliding abrasion.

Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Schlauchbeutelmaschine nach dem Oberbegriff des Anspruchs 1. Derartige Schlauchbeutelmaschinen haben zum Bilden einer Längsnaht entweder eine Siegelbacke oder ein mitlaufendes, beheiztes Schweißband, wobei der Schlauch zwischen der Siegelbacke oder dem Schweißband und dem Formrohr kontinuierlich gefördert und die Längsnaht des Schlauchs gleichzeitig unter Zufuhr von Wärme und Druck gebildet wird. Dabei findet zwischen den Oberflächen der Längsnaht und des Formrohrs, sowie bei Verwendung einer Siegelbacke auch zwischen der Längsnaht des Schlauchs und der Siegelbacke Gleitreibung statt. Probleme treten bei den ansonsten zufriedenstellend arbeitenden Schlauchbeutelmaschinen dann auf, wenn beispielsweise besonders dünne Folienmaterialien, oder solche Folienmaterialien mit schlechten Gleitreibungseigenschaften verarbeitet werden sollen. Derartige Folienmaterialien lassen sich entweder überhaupt nicht, oder nur nach lange andauernden Einstellungsarbeiten bezüglich der Siegeltemperatur und/oder des Siegeldruckes an den beiden Siegelbacken verarbeiten. The invention is based on a tubular bag machine the preamble of claim 1. Such Tubular bag machines have to form a longitudinal seam either a sealing jaw or a moving, heated one Sweatband, with the tube between the sealing jaw or the sweatband and the forming tube continuously promoted and the longitudinal seam of the hose at the same time under Supply of heat and pressure is formed. It takes place between the surfaces of the longitudinal seam and the molded tube, as well as when using a sealing jaw between the Longitudinal seam of the hose and the sealing jaw sliding friction instead of. Problems occur with the otherwise satisfactory working tubular bag machines then when for example, particularly thin film materials, or such sheet materials with poor Dynamic friction properties are to be processed. Such film materials can either be not, or only after a long period of adjustment work regarding the sealing temperature and / or the sealing pressure process the two sealing jaws.  

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Schlauchbeutelmaschine mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß auch Längsnähte an solchen Folienmaterialien stets sicher und zuverlässig gebildet werden können, die beispielsweise besonders dünn sind oder schlechte Gleitreibungseigenschaften aufweisen. Dies wird erfindungsgemäß dadurch erreicht, daß die Schlauchbeutelmaschine zum Bilden der Längsnaht des Schlauches Schweißelemente aufweist, die an der Längsnaht anliegen und mit der selben Geschwindigkeit in Förderrichtung des Schlauches bewegt werden wie der Schlauch selbst. Dadurch tritt zwischen den Schweißelementen und der Längsnaht des Schlauches keine Gleitreibung auf, sondern es wird lediglich der von den Schweißelementen erzeugte Druck und die Wärme auf das Folienmaterial übertragen.The tubular bag machine according to the invention with the characteristic features of claim 1 has in contrast the advantage that longitudinal seams on such Foil materials always formed safely and reliably can be, for example, which are particularly thin or have poor sliding friction properties. this will achieved in that the Tubular bag machine for forming the longitudinal seam of the Hose has welding elements on the longitudinal seam fit in and at the same speed The conveying direction of the hose can be moved like the hose itself. This occurs between the welding elements and the Longitudinal seam of the hose no sliding friction, but it only the pressure generated by the welding elements and transfer the heat to the film material.

Weitere Vorteile und vorteilhafte Weiterbildungen der erfindungsgemäßen Schlauchbeutelmaschine ergeben sich aus den Unteransprüchen und der Beschreibung.Further advantages and advantageous developments of Tubular bag machine according to the invention result from the dependent claims and the description.

In einer bevorzugten Ausführungsform der Erfindung sind die Schweißelemente als jeweils um zwei Rollen umlaufende Schweißbänder ausgebildet. Der zum Bilden der Längsnaht erforderliche Siegeldruck läßt sich in einfacher Weise durch einen Pneumatikzylinder einstellen, der mit den beiden Siegelbacken verbunden ist, wobei die beiden Siegelbacken auf Führungen gegeneinander verschiebbar angeordnet sind. In a preferred embodiment of the invention, the Welding elements as rotating around two roles Sweatbands trained. The one to form the longitudinal seam required sealing pressure can be done in a simple manner adjust a pneumatic cylinder, which with the two Sealing jaws is connected, the two sealing jaws are arranged on guides against each other.

Die Längsnahtsiegeleinrichtung 25 hat zwei übereinander angeordnete, zylindrische Führungsstangen 26, 27, auf denen zwei gegeneinander verschiebbare Längsnahtschweißelemente 28, 29 gleitend geführt sind. Zum Verschieben der beiden Längsnahtschweißelemente 28, 29 auf den Führungsstangen 26, 27 ist auf der dem Formrohr 15 abgewandten Seite der Längsnahtsiegeleinrichtung 25 ein Pneumatikzylinder 30 angeordnet, der mit den beiden Längsschweißelementen 28, 29 verbunden ist. Vorzugsweise ist eines der beiden Längsnahtschweißelemente 28, 29 in horizontaler Richtung federnd gelagert, um einen gleichmäßigen Siegeldruck auf die Längsnaht 35 des Schlauches 12 zu erzielen. Ferner ist die komplette Längsnahtsiegeleinrichtung 25, beispielsweise zu Wartungszwecken, vom Formrohr 15 horizontal wegschwenkbar. Dies erfolgt bevorzugt durch eine nicht dargestellte, pneumatische Einrichtung.The longitudinal seam sealing device 25 has two cylindrical guide rods 26 , 27 arranged one above the other, on which two longitudinal seam welding elements 28 , 29 which are displaceable relative to one another are guided in a sliding manner. To move the two longitudinal seam welding elements 28 , 29 on the guide rods 26 , 27 , a pneumatic cylinder 30 is arranged on the side of the longitudinal seam sealing device 25 facing away from the molded tube 15 and is connected to the two longitudinal welding elements 28 , 29 . One of the two longitudinal seam welding elements 28 , 29 is preferably spring-mounted in the horizontal direction in order to achieve a uniform sealing pressure on the longitudinal seam 35 of the hose 12 . Furthermore, the complete longitudinal seam sealing device 25 , for example for maintenance purposes, can be pivoted away horizontally from the molded tube 15 . This is preferably done by a pneumatic device, not shown.

Jedes Längsnahtschweißelement 28, 29 besteht aus einer sich vertikal erstreckenden, im wesentlichen quaderförmigen, beheizbaren Siegelbacke 31, 32. In jeder Siegelbacke 31, 32 ist beispielsweise je ein Temperaturfühler 33, 34 zur Regelung der Heiztemperatur integriert. In den Siegelbacken 31, 32 sind Ausnehmungen ausgebildet, die jeweils zwei übereinander angeordnete Rollen 36, 37 formschlüssig umschließen. Die Rollen 36, 37 sind in Drehachsen 38 gelagert, die achsparallel zu den Drehachsen 39 der Abzugsbänder 18 angeordnet sind.Each longitudinal seam welding element 28 , 29 consists of a vertically extending, essentially cuboid, heatable sealing jaw 31 , 32 . A temperature sensor 33 , 34 for controlling the heating temperature is integrated in each sealing jaw 31 , 32 , for example. Recesses are formed in the sealing jaws 31 , 32 , each of which positively encloses two rollers 36 , 37 arranged one above the other. The rollers 36 , 37 are mounted in axes of rotation 38 which are arranged axially parallel to the axes of rotation 39 of the take-off belts 18 .

Um die Rollen 36, 37 in den Siegelbacken 31, 32 ist je ein metallisches, endloses, flexibles Schweißband 40, 41 gespannt. Zum Einstellen der Spannung der Schweißbänder 40, 41 ist zumindest jeweils eine der Rollen 36, 37 an jeder Siegelbacke 31, 32 zur anderen Rolle 36, 37 im Abstand verstellbar angeordnet. Die Schweißbänder 40, 41 liegen auf den der Längsnaht 35 des Schlauches 12 zugewandten Seiten voll flächig auf den dort eben und parallel ausgebildeten Flächen der Siegelbacken 31, 32 auf. Auf den der Längsnaht 35 abgewandten Seiten sind die Schweißbänder dagegen mit Abstand zu den Siegelbacken 31, 32 geführt.A metallic, endless, flexible sweatband 40 , 41 is stretched around the rollers 36 , 37 in the sealing jaws 31 , 32 . To adjust the tension of the sweatbands 40 , 41 , at least one of the rollers 36 , 37 on each sealing jaw 31 , 32 is arranged such that it can be adjusted at a distance from the other roller 36 , 37 . The sweat bands 40 , 41 lie on the sides facing the longitudinal seam 35 of the hose 12 over the entire surface on the surfaces of the sealing jaws 31 , 32 which are flat and parallel there. On the other hand, on the sides facing away from the longitudinal seam 35 , the sweatbands are guided at a distance from the sealing jaws 31 , 32 .

Die dem Mundstück 19 zugewandten unteren Rollen 36 sind mit je einem separaten Antrieb 42, 43 gekoppelt, der beispielsweise mittels je eines Riementriebs 44, 45 auf die jeweilige Rolle 36 einwirkt.The lower rollers 36 facing the mouthpiece 19 are each coupled to a separate drive 42 , 43 , which acts on the respective roller 36 by means of a belt drive 44 , 45 , for example.

Wie aus der Fig. 3 ersichtlich sind zwischen der Längsnahtsiegeleinrichtung 25 und der Quernahtsiegeleinrichtung 20 zwei horizontal gegeneinander verfahrbare Rändelrollen 46, 47 für die Längsnaht 35, sowie eine nachgeordnete Leitplatte 48 zum Umlegen der Längsnaht 35 gegen die Schlauchwand am Formrohr 15 angeordnet.As can be seen from FIG. 3, between the longitudinal seam sealing device 25 and the transverse seam sealing device 20, two knurled rollers 46 , 47 for the longitudinal seam 35 , which can be moved horizontally relative to one another, and a downstream guide plate 48 for folding the longitudinal seam 35 against the hose wall on the molded tube 15 are arranged.

Die oben beschriebene Schlauchbeutelmaschine 10 arbeitet wie folgt: Mittels der beiden Abzugsbänder 18 wird die in Rollenform bevorratete endlose Packstoffbahn 13 über die Rolle 16 der Schlauchformeinrichtung 11 kontinuierlich zugeführt. Die Schlauchformeinrichtung 11 formt aus der Packstoffbahn 13 mittels der Formschulter 14 den Schlauch 12, der an dem Formrohr 15 anliegend in Richtung der Quernahtsiegeleinrichtung 20 weitergefördert wird, welche auf an sich bekannte Art einzelne Beutelpackungen vom Schlauch 12 abtrennt. Die Beutelpackungen wurden zuvor beispielsweise durch ein innerhalb des Formrohrs 15 angeordnetes, nicht dargestelltes Füllrohr mit insbesondere flüssigem oder körnigem Füllgut befüllt. The bagging machine 10 described above operates as follows: By means of the two removal belts 18 is in roll form reservoired endless packaging material web 13 is continuously fed through the roller 16 of the tube shaping device. 11 The tube forming device 11 forms the tube 12 from the packaging material web 13 by means of the molding shoulder 14, which tube is conveyed against the molding tube 15 in the direction of the transverse seam sealing device 20 , which separates individual bag packs from the tube 12 in a manner known per se. The bag packs were previously filled, for example, with a liquid or granular filling material, which is arranged inside the shaped tube 15 and is not shown.

Zur Bildung der vom Schlauch 12 senkrecht abstehenden Längsnaht 35 werden die beiden Siegelbacken 31, 32 durch den Pneumatikzylinder 30 gegeneinander gefahren, so daß die beiden Schweißbänder 40, 41 in Kontakt mit den zugewandten Seiten der Längsnaht 35 gelangen, wobei gleichzeitig die beiden Schweißbänder 40, 41 mit solchem Druck gegeneinander gepreßt werden, daß unter der Einwirkung der Wärme die Längsnaht 35 gebildet wird. Die Übertragung der Wärme der Siegelbacken 31, 32 auf die Schweißbänder 40, 41 erfolgt im Bereich der Längsnaht 35 durch das vollflächige Anliegen der Schweißbänder 40, 41 an den entsprechenden Flächen der Siegelbacken 31, 32. Auf den der Längsnaht 35 gegenüberliegenden Seiten sowie im Bereich der Rollen 36, 37 werden die Schweißbänder 40, 41 durch die von den Siegelbacken 31, 32 abgestrahlte Wärme erhitzt. Um die Wärmeverluste der Schweißbänder 40, 41 gering zu halten sollten die Schweißbänder 40, 41 und die Rollen 36, 37 von den Ausnehmungen der Siegelbacken 31, 32 mit möglichst geringem Abstand und möglichst vollständig umschlossen sein.To form the longitudinal seam 35 projecting vertically from the hose 12 , the two sealing jaws 31 , 32 are moved against one another by the pneumatic cylinder 30 , so that the two sweat bands 40 , 41 come into contact with the facing sides of the longitudinal seam 35 , the two sweat bands 40 , 41 are pressed against each other with such pressure that the longitudinal seam 35 is formed under the action of heat. The heat of the sealing jaws 31 , 32 is transferred to the sweat bands 40 , 41 in the area of the longitudinal seam 35 by the full-surface contact of the sweat bands 40 , 41 on the corresponding surfaces of the sealing jaws 31 , 32 . On the sides opposite the longitudinal seam 35 and in the region of the rollers 36 , 37 , the sweatbands 40 , 41 are heated by the heat radiated by the sealing jaws 31 , 32 . In order to keep the heat losses of the sweatbands 40 , 41 low, the sweatbands 40 , 41 and the rollers 36 , 37 should be enclosed by the recesses of the sealing jaws 31 , 32 with the smallest possible distance and as completely as possible.

Wesentlich ist, daß die Antriebe 42, 43 der Schweißbänder 40, 41 so mit den Abzugsbändern 18 synchronisiert sind, daß die Schweißbänder 40, 41 mit einer Geschwindigkeit umlaufen, die der Fördergeschwindigkeit des Schlauches 12 entspricht. Somit entsteht zwischen den Schweißbändern 40, 41 und der Längsnaht 35 des Schlauches 12 keine Gleitreibung, vielmehr liegen die Schweißbänder 40, 41 auf der Längsnaht 35 vollflächig auf. Auch findet keine Kraftübertragung in Förderrichtung des Schlauches 12 von den Schweißbändern 40, 41 auf die Längsnaht 35 des Schlauches 12 statt. Infolgedessen werden auch keine Längsspannungen von den Schweißbändern 40, 41 in den Schlauch 12 übertragen, wodurch auch bspw. besonders dünne Folienmaterialien, oder solche mit schlechten Gleitreibungseigenschaften gut längsgesiegelt werden können.It is essential that the drives 42 , 43 of the sweatbands 40 , 41 are synchronized with the withdrawal belts 18 in such a way that the sweatbands 40 , 41 rotate at a speed which corresponds to the conveying speed of the hose 12 . Thus, no sliding friction arises between the sweat bands 40 , 41 and the longitudinal seam 35 of the hose 12 , rather the sweat bands 40 , 41 rest on the full length of the longitudinal seam 35 . There is also no transmission of force in the conveying direction of the hose 12 from the sweatbands 40 , 41 to the longitudinal seam 35 of the hose 12 . As a result, no longitudinal stresses are also transmitted from the sweatbands 40 , 41 into the tube 12 , which means that, for example, particularly thin film materials or those with poor sliding friction properties can also be longitudinally sealed well.

Die so gebildete Längsnaht 35 wird im weiteren Verlauf mittels der beiden Rändelrollen 46, 47 gerändelt sowie durch die Leitplatte 48 flach gegen die Schlauchwand umgelegt. Anschließend, werden wie oben bereits beschrieben einzelne Beutelpackungen durch die Quernahtsiegeleinrichtung 20 vom Schlauch 12 abgetrennt.The longitudinal seam 35 thus formed is knurled in the further course by means of the two knurled rollers 46 , 47 and folded flat against the tube wall by the guide plate 48 . Then, as already described above, individual bag packs are separated from the tube 12 by the transverse seam sealing device 20 .

Ergänzend wird bemerkt, daß sowohl die beiden Rändelrollen 46, 47, als auch die Leitplatte 48 zusätzliche Einrichtungen der Schlauchbeutelmaschine 10 darstellen, die bei abgewandelten Ausführungsbeispielen der Erfindung nicht zwingend erforderlich sind. Weiterhin ist es denkbar, zusätzlich eine Kühleinrichtung für die Längsnaht 35, beispielsweise in Form einer Düse, im Bereich der Leitplatte 48 anzuordnen. Diese Düse kann zusätzlich auch das Umlegen der Längsnaht 35 gegen die Schlauchwand bewirken, so daß in diesem Fall auf die Leitplatte 48 verzichtet werden kann. Sollen mit der erfindungsgemäßen Schlauchbeutelmaschine 10 Polyäthylenfolien geschweißt werden, so sind die Kontaktflächen der Schweißbänder 40, 41 mit der Längsnaht 35 bevorzugt mit Teflon zu beschichten, wodurch ein Anhaften der Schweißbänder 40, 41 an der Längsnaht 35 verhindert wird.In addition, it is noted that both the knurled rollers 46 , 47 and the guide plate 48 represent additional devices of the tubular bag machine 10 which are not absolutely necessary in the case of modified exemplary embodiments of the invention. Furthermore, it is conceivable to additionally arrange a cooling device for the longitudinal seam 35 , for example in the form of a nozzle, in the region of the guide plate 48 . This nozzle can also bring about the folding of the longitudinal seam 35 against the hose wall, so that in this case the guide plate 48 can be dispensed with. If polyethylene foils are to be welded with the tubular bag machine 10 according to the invention, the contact surfaces of the sweatbands 40 , 41 with the longitudinal seam 35 should preferably be coated with Teflon, thereby preventing the sweatbands 40 , 41 from adhering to the longitudinal seam 35 .
