Die zu füllenden Packungen P werden von einer geeigneten Verpackungsmaschine 8 bekannter Art bereitgestellt. Eine solche Verpackungsmaschine ist beispielsweise in den F i g. 1 und 2 angedeutet. Die Packungen?, die sich in Form von flachgefalteten Faltschachtelrohlingen in einem nicht gezeichneten Vorratsstapel befinden, werden mittels eines FaItschachtelanlegers 9 zwischen Mitnehmer 10, die mittels eines Bandes 11 mit gleichbleibender Geschwindigkeit bewegt werden, eingesetzt und dabei zu einer rechteckigen Röhre aufgefaltet. Mittels einer nicht gezeichneten Weiche und einer bekannten, sich standig drehenden Faltscheibe 12 werden die nach unten zeigenden Lappen an den Schmalseiten der Packungen rechtwinklig umgebogen. Weitere nicht gezeichnete Weichen biegen die an den Breitseiten der Pakkungen befindlichen Lappen rechtwinklig nach außen um, so daß letztere von einer Beleimvorrichtung 13 von unten her mit einem Leimauftrag versehen werden können. Die beleimten Lappen werden von weiteren nichtgezeichneten Weichen um 180° zurückgebogen, so daß sie auf die an die Packungsschmalseiten angrenzenden Lappen zu liegen kommen und auf diese Weise die Packungen an jeweils einem Ende.' verschlossen werden. Nicht gezeichnete Mittel bekannter Art biegen die nach oben hochstehenden Verschlußlappen der Packungen etwa rechtwinklig nach außen während der Zeit um, in der das untere Ende derselben in der genannten Art verschlossen wird. The packs P to be filled are provided by a suitable packaging machine 8 of known type. Such a packaging machine is shown, for example, in FIGS. 1 and 2 indicated. The packs? Which are in the form of flat-folded folding box blanks in a supply stack (not shown) are inserted by means of a folding box feeder 9 between drivers 10, which are moved at a constant speed by means of a belt 11, and are unfolded to form a rectangular tube. By means of a switch (not shown) and a known, constantly rotating folding disc 12, the downwardly pointing tabs are bent over at right angles on the narrow sides of the packs. Further points, not shown, bend the tabs located on the broad sides of the packets outwards at right angles so that the latter can be provided with an application of glue from below by a gluing device 13. The glued flaps are bent back by 180 ° by further switches, not shown, so that they come to rest on the flaps adjoining the narrow sides of the pack and in this way the packs at one end. be locked. Not shown means of a known type bend the upwardly protruding closure tabs of the packs approximately at right angles outwards during the time in which the lower end of the same is closed in the aforementioned manner.

Beim Ablaufen des Fördermittels 3 von der Umlenkscheibe 4 bringt dieses die einzelnen Zwischentrichter 1 mit den darunter in einer Reihe und mit gleicher Geschwindigkeit geförderten Packungen P in Deckung. Mittels eines in Förderrichtung der Pakkungen ansteigenden, an einer Trag- und Rüttelschiene 14 befindlichen Flächenteils 15 werden nun die Packungen angehoben, so daß die Zwischentrichter 1 ein Stück weit in die Packungsöffnungen hineinragen. When the conveying means 3 runs off the deflecting disk 4, it brings the individual intermediate hoppers 1 into line with the packs P conveyed in a row underneath and at the same speed. By means of a surface part 15 which rises in the conveying direction of the packs and is located on a support and vibrating rail 14, the packs are now raised so that the intermediate hoppers 1 protrude a little into the pack openings.

Die an einem Förclerkettenpaar 23 bekannter Art kippbar angebrachten Förderbecher 16 bringen die in bekannter Weise abgemessenen Füllgutmengen zu den. Schütttrichtern 17, die an einem weiteren Band 18 befestigt sind. Das Band 18, das um zwei Scheiben 19, 20 herumgeführt ist, von denen die Scheibe 20 von der Maschine aus angetrieben wird, bringt die Schütttrichter 17 auf einem Teil des Umlaufwegs der Zwischentrichter 1 im Gleichlauf mit diesen zur Dekkung. Während eines Teils der genannten Zeit ragen in bereits beschriebener Weise die Zwischentrichter 1 in die Packungen P hinein, so daß das Befüllen der Packungen durch Öffnen von an den Schütttrichtern 17 vorgesehen, in bekannter Weise betätigten Absperrschiebern 24 durch die genannten Zwischentrichter 1 hindurch erfolgt.The conveyor buckets 16, which are tiltably attached to a conveyor chain pair 23 of a known type, bring the quantities of filling material measured in a known manner to the. Hopper 17, which are attached to a further belt 18. The belt 18, which is guided around two disks 19, 20, from which the disk 20 is driven by the machine, brings the hoppers 17 to cover part of the circulation path of the intermediate hoppers 1 in synchronism with them. During part of the time mentioned, the intermediate funnels 1 protrude into the packs P in the manner already described, so that the packs are filled by opening shut-off slides 24, which are provided on the pouring hoppers 17 and operated in a known manner, through the said intermediate funnels 1.

Das von den Schütttrichtern 17 aus abgeschüttete Füllgut nimmt zunächst noch ein größeres Volumen als das auf Grund der Packungsabmessungen zur Verfügung stehende Volumen ein. Durch Rütteln der Packungen P mittels der Schiene 14 setzt sich das Füllgut in den Packungen, bis sich sein oberer Spiegel bis nahe an oder nur wenig unter die Schließkante der Packungen abgesenkt hat.The filling material poured off from the bulk hoppers 17 initially takes up a larger volume than the volume available due to the package dimensions. By shaking the Packs P by means of the rail 14, the filling material is seated in the packs until its upper level is reached has lowered to close to or just a little below the closing edge of the packs.

Inzwischen sind die in die Packungen P hineinragenden Zwischentrichter 1 mit den an im Tragkörper 7 senkrecht längsverschiebbaren Führungsstangen 6 befestigten und mit diesem Tragkörper 7 umlaufenden Eindrückstempeln 2 zur Deckung gekommen. Durch Niedergehen der Stempel 2 werden nun die gegebenenfalls über den oberen Rand der Pakkung P hinaus in die Zwischentrichter 1 noch hineinragende Füllguteinzelstücke in die Packungen hineingeschoben. Der Antrieb der Eindrückstempel 2 kann dabei in jeder beliebigen bekannten Art erfolgen. Die untere Endlage der Eindrückstempel 2 ist entsprechend den Füllguteigenschaften so einstellbar, daß nicht mehr als unbedingt notwendig gepreßt wird und somit unnötiger Bruch von Füllgutstücken vermieden wird.In the meantime, the intermediate funnels 1 protruding into the packs P have come to coincide with the push-in punches 2 which are fastened to guide rods 6 which are vertically longitudinally displaceable in the support body 7 and which encircle this support body 7. By lowering the stamps 2, the individual fillings that may still protrude beyond the upper edge of the pack P into the intermediate funnel 1 are pushed into the packs. The drive of the push-in punches 2 can take place in any known manner. The lower end position of the indenter 2 can be adjusted according to the properties of the product so that it is not pressed more than is absolutely necessary and thus unnecessary breakage of the product is avoided.

Nach beendetem Füllvorgang werden die Eindrückstempel 2 zurückgezogen und die Packungen P im Verlauf des weiteren Förderweges so weit abgesenkt, daß die Zwischentrichter 1 von neuem an leere Packungen herangeführt und wie oben geschildert mit diesen zur Deckung gebracht werden können.When the filling process is complete, the indenters 2 are withdrawn and the packs P are lowered so far in the course of the further conveying path that the intermediate funnel 1 can again be brought up to empty packs and, as described above, can be brought into congruence with them.

Das Verschließen der Packungen wird in bekannter Weise so vorgenommen, daß zunächst mittels eines weiteren Leimauftraggeräts 21 die an die Breitseiten der Packungen P angrenzenden Verschlußlappen mit einem Leimauftrag versehen und anschließend die in Förderrichtung zeigenden schmalen Verschlußlappen entgegen der Förderrichtung mit Hilfe von nicht gezeichneten Weichen umgebogen werden, bis sie sich im rechten Winkel zu den ihnen zugeordneten Schmalseiten der Packungen befinden, worauf dann mittels einer weiteren Faltscheibe 22 die den zuerst genannten schmalen Lappen gegenüberliegenden Lappen in Richtung auf dieselben hin gebogen und zuletzt mittels weiterer nicht gezeichneter Weichen die an die Packungsbreitseiten angrenzenden Lappen auf die genannten schmalen Lappen umgelegt werden.The packs are closed in a known manner by first applying glue to the closing tabs adjacent to the broad sides of the packs P by means of another glue applicator 21 and then bending the narrow closing tabs pointing in the conveying direction against the conveying direction with the aid of switches (not shown) until they are at right angles to the narrow sides of the packs assigned to them, whereupon the tabs opposite the first-mentioned narrow tabs are bent towards the same by means of a further folding disk 22 and finally the tabs adjoining the broad sides of the pack by means of further switches (not shown) be folded over the said narrow flaps.

Ergänzend sei noch darauf hingewiesen, daß die Wände der Zwischentrichter 1 nicht wie im vorliegenden Ausführungsbeispiel in ihrer ganzen Höhe parallel und geradlinig verlaufen müssen, da es je nach Art und Anordnung der Füllgutabmeßvorrichtungen und des Füllgutzuführsystems zweckmäßig sein kann, die Zwischentrichter 1 an ihrem oberen Ende mit trichterförmigen Erweiterungen zu versehen.It should also be pointed out that the walls of the intermediate funnel 1 are not as in the present case Embodiment must run parallel and in a straight line in its entire height, as it ever appropriate according to the type and arrangement of the Füllgutabmeßvorrichtungen and the Füllgutzuführsystem can be to provide the intermediate funnel 1 at its upper end with funnel-shaped extensions.
