Description

Die vorliegende Erfindung betrifft ein Verfahren zum Bilden von Beutelstapeln aus Beuteln, eine Vorrichtung zur Durchführung eines dieser Verfahren sowie eine Vorrichtung zum Herstellen von Flachbeuteln.The present invention relates to a method for forming bag stacks from bags, to an apparatus for carrying out one of these methods and to an apparatus for producing flat bags.

Das Stapeln von Beuteln ist ein lange bearbeitetes Problemfeld. Auch die DE 35 24 203 C2 beschäftigt sich unter anderem mit den damit verbundenen Problemen. Nach dem Stand der Technik werden Flachbodenbeutel gefertigt, indem direkt von einem Förderzylinder Beutel mit den gerade gebildeten Böden senkrecht auf eine Ablage abgestellt werden- Hierbei zeigt die Öffnung des Beutels nach oben. Die Stapel werden also gebildet, indem die Beutel aneinander gereiht werden. Sie berühren sich hierbei mit ihren Frontseiten. Dieses Verfahren hat sich jedoch dann als nachteilig erwiesen, wenn die Länge der Beutel zunimmt.Stacking bags is a long-standing problem area. Also the DE 35 24 203 C2 deals among other things with the associated problems. According to the state of the art flat bottom bags are made by directly from a conveyor cylinder bag with the bottoms just formed perpendicular to a shelf be parked Here, the opening of the bag points upwards. The stacks are thus formed by the bags are strung together. They touch each other with their front pages. However, this method has proved disadvantageous as the length of the bags increases.

Die US 4,357,126 zeigt ein Verfahren, bei dem die Beutel auf eine ihrer Frontseiten abgelegt und so gestapelt werden.The US 4,357,126 shows a method in which the bags are placed on one of their front sides and stacked so.

Insbesondere bei Pinchbodenbeuteln wird in den letzten Jahren eine Steigerung der Länge derselben gefordert. Die entstehenden Beutel lassen sich nur noch schlecht senkrecht abstellen.Especially in Pinchbodenbeuteln an increase in the length of the same is required in recent years. The resulting bags can be parked only bad vertical.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Stapelverfahren vorzuschlagen, bei welchem in zuverlässiger Weise Beutelstapel gebildet werden.The present invention has for its object to propose a stacking method in which bag stacks are formed in a reliable manner.

Die erfindungsgemässe Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.The inventive object is achieved by the features of the characterizing part of claim 1.

Bei der Ausgestaltung dieses Verfahrens findet ein Riemen-Zangen-System Verwendung, welches die Beutel bis zu der Ablagestelle transportiert und in geeigneter Weise ausrichtet.In the design of this method, a belt-tongs system is used, which transports the bags up to the deposit and aligned in a suitable manner.

Die vorliegende Erfindung sieht vor, dass die nachfolgenden Pinchbodenbeutel an die bereits auf dem Stapel befindlichen, abgelegten Beutel herangeführt werden, während die nachfolgenden Beutel den bereits abgelegten Beuteln ihre Frontseite, auf die die Pinchfaltung zurückgeklappt ist, zuwenden. Wird von diesem Verfahren abgewichen, besteht die Gefahr, dass die nachfolgenden Beutel die gerade verklebten Pinchböden der abgelegten Beutel wieder öffnen, indem sie mit ihrem voraneilenden Ende in die Faltung eingreifen. Aus Geschwindigkeitsgründen kann die Verwendung mehrerer Riemen-Zangen-Systeme und das Vorsehen mehrerer Ablagestellen notwendig werden. In diesem Falle können die Riemen-Zangen-Systeme an Ablagestellen sequentiell eingesetzt werden, eine Weiche regelt dann die Zufuhr der Beutel zu dem sich jeweils in Betrieb befindlichen System, so dass unter anderem zwei dieser Systeme abwechselnd zum Einsatz kommen. Auf diese Weise kann beispielsweise Zeit für das Ausschleusen der bereits gebildeten Stapel gewonnen werden. Hierbei kann es vorteilhaft sein, wenn das Riemen-Zangen-System die Beutel um 180° dreht, so dass diejenige Frontseite am Ende des Transportes mit dem Riemen-ZangenSystem dem Stapel zugewandt ist, die ohne das Riemen-Zangen-System dem Stapel abgewandt wäre.The present invention provides that the following Pinchbodenbeutel are brought to the already on the stack, deposited bag, while the subsequent bag the already deposited bags their front page, on which the pinch fold is folded back turn. If this method is deviated from, there is a risk that the subsequent bags reopen the just glued Pinchböden the deposited bag by engaging with its leading end into the fold. For speed reasons, the use of multiple belt-tongs systems and the provision of multiple storage locations may be necessary. In this case, the belt-tongs systems can be used sequentially at storage locations, a diverter then controls the supply of the bags to each operating system, so that inter alia, two of these systems are used alternately. In this way, for example, time can be gained for discharging the already formed stacks. It may be advantageous if the belt-tongs system rotates the bag by 180 °, so that the front side at the end of the transport with the belt-tongs system faces the stack, which would be facing away from the stack without the belt-tongs system ,

Fig. 1 zeigt eine Flachund Seitenfaltenbeutelmaschine 1 mit einem Falzund Transportzylinder 2, auf dem ein Teil der Pinchboden-Beutelherstellung vorgenommen wird. Ein solcher Falzund Transportzylinder 2 verfügt über mehrere Zangen 3, von denen Beutel oder Beutelhalbzeuge aufgenommen werden können. Die Rotation des Falzund Transportzylinders 2 um seine Achse 4 führt diese Beutel beziehungsweise Beutelhalbzeuge zu verschiedenen Bearbeitungsstationen und auch an dem oberen Falzzylinder (Falzmesser) 5 vorbei. Die genaue Ausgestaltung einer solchen Beutelmaschine 1, die ja auch ein Maschinengestell 6 umfasst, ist jedoch nicht Gegenstand des vorliegenden Patentbegehrens. Vielmehr geht es an dieser Stelle darum, zu zeigen, dass die Beutel auf einer Beutelablage 7 abgelegt werden, wobei die Beutel 9 sich in ihrer vertikalen Erstreckung dort aneinander reihen. Die Beutel 9 werden am Umkippen von der Beutelstütze 8 gehindert. Die Folge dieser üblichen Maßnahme sind jedoch sehr instabil gestapelte Beutel, welche kurz nach ihrer Verklebung darüber hinaus einer schädlichen Belastung ausgesetzt werden. Fig. 1 shows a flat and side-folding bag machine 1 with a folding and transport cylinder 2, on which a part of Pinchboden bag making is made. Such folding and transport cylinder 2 has a plurality of pliers 3, of which bags or semi-finished bag can be added. The rotation of the folding and transport cylinder 2 about its axis 4 leads these bags or bag semi-finished products to different processing stations and also past the upper folding cylinder (folding blade) 5. The exact configuration of such Bag machine 1, which indeed includes a machine frame 6, but is not the subject of the present patent application. Rather, it is at this point to show that the bags are placed on a bag tray 7, wherein the bags 9 line up in their vertical extent there. The bags 9 are prevented from tipping over by the bag support 8. The result of this usual measure, however, are very unstably stacked bags, which are also exposed to a harmful burden shortly after their bonding.

Figur 2 zeigt eine Beutelmaschine 1, welche mit einer erfindungsgemäßen Vorrichtung ausgestattet ist. Die Beutelmaschine 1 verfügt wieder über einen Falz- und Transportzylinder 2 und einen oberen Falzzylinder (Falzmesser) 5. Die Beutel 9 werden von der Ausschleusung 15 zum Verlassen des Falz- und Transportzylinders 2 gebracht und werden einem Doppelbandförderer 10a übergeben. Von diesem werden die Beutel 9 an eine Weiche 11 geführt, welche darüber entscheidet, ob die Beutel 9 dem Doppelbandförderer 10b oder dem Doppelbandförderer 10c übergeben werden. Der Doppelbandförderer 10b beschickt eine obere Ablagevorrichtung, während Doppelbandförderer 10c eine untere Ablagevorrichtung beschickt. Nach dem Durchlaufen dieser Doppelbandförderer 10b und 10c gelangen die Beutel an Übergabestationen 12b,c, von welcher sie jeweils dem zugehörigen Riemen-Zangen-System 13b oder c übergeben werden. Die besagten Riemen 13b und 13c laufen auf den Transportwalzen 14. Die beiden Riemen-Zangen-Systeme 13b und 13c sind jeweils mit Greifern beziehungsweise Zangen 16 ausgestattet, welche die Beutel 9 mit sich fortführen. Die Beutel 9 werden durch das Riemen-Zangen-System gegenüber den Ablagestellen 17b und 17c um 180 ° gedreht. Im vorliegenden Fall trägt diese Drehung dazu bei, dass die Seite der neu auf den Stapel hinzukommenden Frontseite des jeweiligen Beutels, auf die die Pinchfaltung abgelegt ist, auf diejenige Frontseite der bereits abgelegten Beutel trifft, welche eben keine Pinchfaltung aufweist und welche damit glatt beschaffen ist. FIG. 2 shows a bagging machine 1, which is equipped with a device according to the invention. The bag machine 1 again has a folding and transport cylinder 2 and an upper folding cylinder (folding blade) 5. The bags 9 are brought from the discharge 15 for leaving the folding and transporting cylinder 2 and are handed over to a double belt conveyor 10a. From this, the bags 9 are guided to a switch 11, which decides whether the bags 9 are transferred to the double belt conveyor 10b or the double belt conveyor 10c. The double belt conveyor 10b feeds an upper tray, while double belt conveyor 10c feeds a lower tray. After passing through these double belt conveyors 10b and 10c, the bags pass to transfer stations 12b, c, from which they are respectively transferred to the associated belt-tongs system 13b or c. The said belts 13b and 13c run on the transport rollers 14. The two belt-tongs systems 13b and 13c are respectively provided with grippers or tongs 16 which carry the bags 9 with them. The bags 9 are rotated by the belt-tongs system with respect to the storage locations 17b and 17c by 180 °. In the present case, this rotation contributes to the fact that the side of the newly added to the stack front of each bag on which the Pinchfaltung is placed on the front of the already deposited bag meets, which just has no pinch fold and which is so smooth ,

Die Figur 2 zeigt eine Vielzahl von Beuteln 9 an den Ablagestellen 17. Wenn diese Beutelstapel an den Ablagestellen 17 eine bestimmte Anzahl von Beuteln aufweisen, werden die entsprechenden Beutelstapel in Richtung des Pfeiles 18 von der jeweiligen Ablagestelle weg transportiert. Während dieser Zeit wird das Riemen-Zangen-System 13b oder 13c aktiviert, und die Weiche 11 leitet diesen über die jeweiligen Doppelbandförderer 10b und 10c die Beutel 9 zu. Auf diese Weise bleibt für den Ausschleusungsvorgang der entsprechenden Beutelstapel von den Beutelablagestellen 17 genügend Zeit.The FIG. 2 shows a plurality of bags 9 at the storage locations 17. When these bags stack at the storage locations 17 a certain number of bags have, the corresponding bag stack in the direction of arrow 18 are transported away from the respective storage location. During this time, the belt-tongs system 13b or 13c is activated, and the switch 11 supplies the bags 9 via the respective double-belt conveyors 10b and 10c. In this way, enough time remains for the Ausschleusungsvorgang the corresponding bag stack of the bag depositories 17.

Figur 3 zeigt ein Schema eines Flachbeutels 9 mit einem Pinchboden, welcher einen zurückgefalteten Bodenbereich 19 aufweist, der auf eine Frontseite 21 zurückgeklappt und mit dieser durch Klebung verbunden ist. Der Abstand der zurückgeklappten Lasche 19 von der Frontseite 21 wurde übertrieben dargestellt. Der Seite 21 gegenüber liegt die glatte Seite 20, auf die eben kein Bodenteil 19 zurückgeklappt wurde. FIG. 3 shows a schematic of a flat bag 9 with a Pinchboden, which has a folded-back bottom portion 19 which is folded back on a front side 21 and connected thereto by gluing. The distance of the folded-back flap 19 from the front 21 was exaggerated. The side 21 opposite is the smooth side 20, on which no bottom part 19 has been folded back.

In Figur 4 ist noch einmal dargestellt, wie sich solche Beutel 9 in vorteilhafter Ausführung der Erfindung stapeln lassen. Die Beutel werden aufeinander gestapelt, während sich die Frontseite 21 mit dem zurückgeklappten Teil des Bodens 19 der glatten Seite 20 der bereits abgelegten Beutel zuwendet. Der Beutel 9, der gerade abgelegt wird, wird dabei noch in der Richtung z transportiert. Natürlich kommen in dem Ablegestadium auch Bewegungskomponenten in der vertikalen Richtung x hinzu.
