Abstract

In order to fill bags with bulk material, in particular with cereal products, expandable shaping elements (46, 47; 48, 49) are jointly pushed into the aperture of a bag (42) which was folded flat. The bag (50), with the inserted shaping elements, is introduced into a rigid packaging (52). The shaping elements (46, 47) are expanded, in order to widen the bag (42), the bag being filled with the bulk material between the expanded shaping elements. Finally, the shaping elements are retracted from the bag. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Füllen von Beuteln mit Schüttgut gemäss Anspruch 1 sowie eine Vor­richtung zur Durchführung des Verfahrens nach Anspruch 7.The present invention relates to a method for filling bags with bulk material according to claim 1 and a device for carrying out the method according to claim 7.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Füllen von Beuteln zu schaffen, das eine gute Beutelformung und eine sichere Abfüllung für sperrige Produkte gestattet.The invention has for its object to provide a method for filling bags that allows good bag shape and safe filling for bulky products.

Diese Aufgabe wird erfindungsgemäss durch ein Verfahren nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in weiteren Ansprüchen angegeben.According to the invention, this object is achieved by a method according to claim 1. Advantageous embodiments of the invention are specified in further claims.

Nachfolgend wird die Erfindung beispielsweise anhand einer Zeichnung näher erläutert. Dabei zeigt:

  • Fig. 1 eine schematische Darstellung einer Anlage mit einer Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens, und
  • Fig. 2 eine schematische Darstellung einer Ausführung der Arbeitsweise einer solchen Vorrichtung.
The invention is explained in more detail below, for example with reference to a drawing. It shows:
  • Fig. 1 is a schematic representation of a system with a device for performing the method according to the invention, and
  • Fig. 2 is a schematic representation of an embodiment of the operation of such a device.

In der in Fig. 1 schematisch dargestellten Einrichtung werden links Beutel und rechts Schachteln hergestellt. Die Beutel können aus einer kontinuierlichen Bahn 1 hergestellt werden, die aus einem warmverschweissbaren Material besteht, das mit einer Schweissnaht längs aneinanderstossender Längsränder versehen ist. Die benachbarten Enden von aufeinanderfolgend hergestellten Beuteln 2, 3, 4, 5, 6 werden warmverschweisst und abgeschnitten oder voneinander getrennt. Die in Fig. 1 dargestellten Beutel 5 und 6 sind bereits abgetrennt.In the device shown schematically in FIG. 1, bags are made on the left and boxes on the right. The bags can be produced from a continuous web 1, which consists of a heat-weldable material, which is provided with a weld seam along longitudinally abutting longitudinal edges. The adjacent ends of successively produced bags 2, 3, 4, 5, 6 are heat-sealed and cut off or separated from one another. The bags 5 and 6 shown in Fig. 1 are already separated.

Die Schachteln bilden steife Verpackungen, beispielsweise aus vorgeformten Kartons 11, die zuerst am Boden geschlossen werden, während die oberen Schliesslappen offen, vorzugsweise horizontal nach aussen gestreckt bleiben. Die Schachteln 12, 13, 14, ..., werden in an sich bekannter Weise geformt und in die Nähe der Beutel gebracht. Die Beutel 2, 3, 4, 5, 6 befinden sich nach dem Verschweissen und Trennen in einem flachgefalteten Zustand. Um die Beutel auszuspreizen sind Spreizvorrichtungen 21, 22, 23, ..., vorgesehen, die im ge­schlossenen Zustand in die gefalteten Beutel bis zum Beutel­grund eingeführt werden, um sie nachher zu öffnen und da­durch jeweils die Vorderwand von der Rückwand eines Beutels auseinanderzustrecken. In Fig. 1 ist die geschlossene Spreiz­vorrichtung 21 vorbereitet, um in einen Beutel eingeführt zu werden; die geschlossene Spreizvorrichtung 22 ist teil­weise und die geschlossene Spreizvorrichtung 23 gänzlich in den Beutel 5 bzw. 6 eingeführt.The boxes form rigid packaging, for example from preformed cardboard boxes 11, which are first closed on the floor, while the upper closing flaps remain open, preferably horizontally stretched outwards. The boxes 12, 13, 14, ... are shaped in a manner known per se and brought into the vicinity of the bags. The bags 2, 3, 4, 5, 6 are in a flat folded state after welding and separation. In order to spread out the bags, spreading devices 21, 22, 23,... Are provided which, in the closed state, are inserted into the folded bags up to the bottom of the bag in order to subsequently open them, thereby opening the front wall from the rear wall of a bag to spread apart. In Fig. 1, the closed spreader 21 is prepared to be inserted into a bag; the closed spreading device 22 is partially inserted and the closed spreading device 23 entirely in the bag 5 or 6.

In einem weiteren Verfahrensschritt werden die Beutel mit den eingesteckten, vorzugsweise noch geschlossenen Spreiz­vorrichtungen mindestens teilweise in die Schachteln einge­führt, um in dieser Lage die Beutel durch Oeffnen der Spreiz­vorrichtungen zu spreizen und sie mit dem Schüttgut zu fül­len. Zu diesem Zweck weist die Einrichtung nach Fig. 1 einen Verteiler 31 auf, mit dessen Hilfe die Beutel gefüllt wer­den. Falls die Beutel am Anfang nur teilweise in die Schach­teln eingeführt wurden, wird diese Operation jetzt vollstän­dig nachgeholt, bis die Beutel zumindest angenähert den Boden der Schachteln berühren. In einem weiteren Verfahrensschritt werden die offenen Spreizvorrichtungen herausgezogen und die Schachteln verschlossen.In a further process step, the bags with the inserted, preferably still closed, spreading devices are at least partially inserted into the boxes in order to spread the bags in this position by opening the spreading devices and to fill them with the bulk material. For this purpose, the device according to FIG. 1 has a distributor 31, by means of which the bags are filled. If the bags were only partially inserted into the boxes at the beginning, this operation is now carried out completely until the bags at least approximately touch the bottom of the boxes. In a further process step, the open spreading devices are pulled out and the boxes are closed.

In Fig. 2 sind zwei taschenförmig oder flach gefaltete Beutel 41 und 42 und eine geschlossene Spreizvorrichtung 43 darge­stellt, die im Begriff ist, in den Beutel 42 eingesteckt zu werden. Eine weitere geschlossene Spreizvorrichtung 44 ist in einen Beutel 45 eingeführt.In Fig. 2 two bag-shaped or flat folded bags 41 and 42 and a closed spreading device 43 are shown, which is about to be inserted into the bag 42. Another closed spreading device 44 is inserted into a bag 45.

Die Vorrichtung 43 weist vier steife Ausformelemente oder Finger 46, 47, 48 und 49 auf, die paarweise ausspreizbar sind. In der Vorrichtung 43 oder 44 befinden sich die Finger in einer geschlossenen Position, bei der sich die Spitzen der Finger 46 und 47 bzw. 48 und 49 nahezu berühren, wobei sie sich vorzugsweise auch an eingeebneten Flächen flach berühren könnten.The device 43 has four rigid shaping elements or fingers 46, 47, 48 and 49, which can be spread out in pairs. In the device 43 or 44 the fingers are in a closed position in which the tips of the fingers 46 and 47 or 48 and 49 almost touch, whereby they could preferably also touch flat on leveled surfaces.

In einen weiteren Beutel 50 ist eine dritte Spreizvorrich­tung 51 eingeführt, deren Ausformelemente oder Finger paar­weise bereits ausgespreizt wurden, so dass der Beutel nicht mehr taschenförmig ist, sondern zumindest angenähert einen Quader oder ein Parallelepiped bildet. Der Beutel 50 mit der eingesteckten offenen Vorrichtung 51 befindet sich oberhalb einer Schachtel 52, in die er in einem späteren Verfahrens­schritt hineingesteckt wird.In a further bag 50, a third spreading device 51 is inserted, the shaping elements or fingers of which have already been spread out in pairs, so that the bag is no longer pocket-shaped, but at least approximately forms a cuboid or a parallelepiped. The bag 50 with the inserted open device 51 is located above a box 52, into which it is inserted in a later process step.

Fig. 2 zeigt auch einen Verteiler in Form eines Löffelpaares 53, das beispielsweise Corn-Flakes oder Maisflocken 54 in einen Beutel 55 fallen lässt. Nachdem ein Beutel 56 mit dem Schüttgut ausgefüllt ist, wird die in ihm noch eingesteckte offene Spreizvorrichtung 57 herausgezogen, und zwar vorzugs­weise indem vor dem Herausbewegen der Spreizvorrichtung die Finger um einen geringen Betrag zusammengezogen wurden.2 also shows a distributor in the form of a pair of spoons 53 which, for example, drops corn flakes or corn flakes 54 into a bag 55. After a bag 56 is filled with the bulk material, the open spreading device 57 still inserted in it is pulled out, preferably by pulling the fingers together by a small amount before the spreading device is moved out.
