Description

Die Erfindung geht aus von einem Verfahren zum Verpacken pulveriger oder körniger Schüttgüter nach dem Oberbegriff des Anspruchs 1, wie es beispielsweise aus der US 5,111,642 bekanntgeworden ist. Ferner betrifft die Erfindung eine Vorrichtung zum Durchführen des neuartigen Verfahrens nach dem Oberbegriff des Anspruchs 13. Bei dem aus der US 5,111,642 bekanntgewordenen Verfahren werden Tablettenpreßlinge gebildet, die in vorbereitete Kapselteile eingeschoben werden. Durch das Bilden der Preßlinge läßt sich eine hohe Dichte des zu verpackenden Schüttgutes erzielen, so daß die Kapselgröße relativ klein gewählt werden kann. Wird ein derartiges Verfahren auf andere Schüttgüter, insbesondere Nahrungs- und Genußmittel angewendet, bei der sich das Schüttgut beispielsweise in einer Umverpackung in Form eines Beutels befindet, so stellt sich das Problem, daß das verdichtete Schüttgut nur schwer aus der Umverpackung entnommen werden kann. Zwar ist es in der DE 25 25 504 A1 erwähnt, daß sich derartig vorgeformte Preßlinge durch Zusatz anderer Stoffe, beispielsweise von Wasser, leicht wieder auflösen lassen. Dies setzt jedoch bereits voraus, daß der Preßling aus der Umverpackung entnommen ist. Wird beispielsweise Kaffee zu einem Preßling vorverdichtet und in einer Umverpackung verpackt, so stellt sich insbesondere die Problematik der Entnahme einzelner Portionen aus der Umverpackung. Aufgabe der Erfindung ist es daher, ein gattungsgemäßes Verfahren zum Verpacken pulveriger oder köringer Schüttgüter derart weiterzubilden, daß eine einfache Entnahme des vorverdichteten Schüttgutes aus der Umverpackung ermöglicht wird. Diese Aufgabe wird durch die kennzeichnenden Merkmale der Ansprüche 1 und 13 gelöst. Weitere Vorteile und vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sowie der Vorrichtung zum Durchführen des erfindungsgemäßen Verfahrens zum Verpacken pulveriger oder körniger Schüttgüter ergeben sich aus den Unteransprüchen und der Beschreibung. The invention is based on a method for packaging powdery or granular bulk goods according to the generic term of claim 1, as for example from US 5,111,642 has become known. The invention further relates to a Device for performing the novel method according to the preamble of claim 13. In the method known from US 5,111,642 Tablet compacts formed into prepared capsule parts be inserted. By forming the compacts leaves there is a high density of the bulk goods to be packed achieve, so that the capsule size chosen to be relatively small can be. Such a procedure will apply to others Bulk goods, especially food and beverages applied, in which the bulk material, for example, in an outer packaging in the form of a bag, so provides the problem is that the compacted bulk material is difficult can be removed from the outer packaging. It is in DE 25 25 504 A1 mentions that such preformed ones Compacts by adding other substances, for example from Water, let it dissolve easily. However, this sets already advance that the compact from the outer packaging is removed. For example, coffee becomes a compact pre-compressed and packed in an outer packaging, so provides in particular the problem of taking individual Portions from the outer packaging. The object of the invention is therefore, a generic method for packaging to further develop powdery or granular bulk goods that a simple removal of the pre-compressed bulk material from the outer packaging is made possible. This task will solved by the characterizing features of claims 1 and 13. Further advantages and advantageous developments of the inventive method and the device for Carrying out the packaging method according to the invention powdery or granular bulk goods result from the Subclaims and the description.

Bescheibung der AusführungsbeispieleDescription of the exemplary embodiments

Bei dem erfindungsgemäßen Verpackungsverfahren wird eine volumetrisch oder gravimetrisch abgemessene Schüttgutmenge 1 gelockert und durch ein Zuführrohr 11 oder einen Zuführkanal in eine hülsenförmige, senkrecht ausgerichtete Matritze 12 einer Presse 10 von oben eingeschüttet. Ein in das untere Ende der Matritze 12 eingeführter Stempel 13 verschließt derweil deren untere Öffnung (Figur la). Nach dem vollständigen Einführen der Schüttgutmenge 1 in den Hohlraum der Matritze 12 (Figur 1b) fährt ein ebenfalls mit der Matritze 12 ausgerichteter zweiter Stempel 14 von oben in den Hohlraum der Matritze 12 und verpreßt die zunächst lockere Schüttgutmenge 1 in der Matritze 12 zu einem Preßling 2, wobei beinahe die gesamte eingeschlossene Luft entweicht (Figur 1c). Der Preßling 2, bei dem die einzelnen Körner oder Teilchen zusammenhaften oder zusammenbacken, wird darauf vom oberen Stempel 14 unter Unterstützung des unteren Stempels 13 nach unten aus der Matritze 12 geschoben (Figur 1d). Ein unterhalb der Matritze 12 waagrecht verfahrbarer Schieber 5 schiebt den noch zwischen den beiden Stempeln 13, 14 gehaltenen Preßling 2 in einen bereitgestellten Beutel 3 (Figur 1e). Während das offene Ende des Beutels 3 durch Falten und Versiegeln zu einer fertigen Packung 4 verschlossen wird (Figur 1f), kehren die Stempel 13, 14 und der Schieber 5 in ihre Ausgangsstellung zurück, so daß ein neuer Verpackungstakt beginnen kann.In the packaging method according to the invention, a Volumetric or gravimetric bulk quantity 1 loosened and through a feed pipe 11 or a feed channel into a sleeve-shaped, vertically aligned die 12 a press 10 poured in from above. One in the bottom Stamp 13 inserted at the end of die 12 closes meanwhile their lower opening (figure la). After this complete introduction of the bulk quantity 1 into the cavity the die 12 (FIG. 1b) also moves in with the Die 12 aligned second punch 14 from above in the cavity of the die 12 and compresses the first loose bulk quantity 1 in the die 12 to one Compact 2, with almost all the trapped air escapes (Figure 1c). The compact 2, in which the individual Adhere or bake grains or particles together, is then from the upper stamp 14 with the support of lower punch 13 pushed down out of the die 12 (Figure 1d). One horizontally below the die 12 movable slider 5 still pushes between the two Stamp 13, 14 held compact 2 in one provided bag 3 (Figure 1e). While the open End of the bag 3 by folding and sealing to one finished package 4 is closed (Figure 1f), the return Stamp 13, 14 and the slide 5 in their starting position back so that a new packaging cycle can begin.

Abweichend von dem Ausführungsbeispiel nach Figur 1, bei dem der Preßling 2 zum Einführen in den Beutel 3 waagrecht verschoben wird, wird beim Ausführungsbeispiel nach Figur 2 der Preßling 2 in senkrechter Richtung in einen aufrecht bereitgestellten Beutel 3 eingeführt. Das Einfüllen einer Schüttgutmenge 1 in eine ebenfalls senkrecht ausgerichtete, hülsenförmige Matritze 12 und das Verdichten zu einem Preßling 2 erfolgen wie beim oben beschriebenen Ausführungsbeispiel nach Figur 1. Nach dem Verdichten fährt jedoch der untere Stempel 13 weit nach unten, und unterhalb der Matritze 12 wird mit deren Hohlraum ausgerichtet ein Beutel 3 bereitgestellt (Figur 2d). In den oben offenen Beutel 3 schiebt nun der obere Stempel 14 den Preßling 2 aus der Matritze 12 durch eine Abwärtsbewegung in den Beutel 3 ein (Figur 2e), und kehrt dann in seine Ausgangsstellung zurück. Der gefüllte Beutel 3 wird zur Seite verfahren, so daß auch der untere Stempel 13 in seine Ausgangslage zurückkehren kann. An dem gefüllten Beutel 3 wird nun der Verschluß des Beutels 3 durch Falten und Siegeln oder Verkleben in an sich bekannter Weise gebildet.Deviating from the embodiment of Figure 1, in which the compact 2 for insertion into the bag 3 horizontally is shifted, is in the embodiment of Figure 2 the compact 2 in an upright vertical direction provided bag 3 introduced. Filling one Bulk quantity 1 in a likewise vertically aligned, sleeve-shaped die 12 and compacting into one Compact 2 take place as described above Exemplary embodiment according to FIG. 1. After compression however the lower punch 13 far down and below the die 12 is aligned with its cavity Bag 3 provided (Figure 2d). In the open ones Bag 3 now pushes the upper punch 14 out of the compact 2 the die 12 by a downward movement into the bag 3 a (Figure 2e), and then returns to its original position back. The filled bag 3 is moved to the side, so that the lower punch 13 in its starting position can return. On the filled bag 3 is now the Closure of the bag 3 by folding and sealing or Gluing formed in a conventional manner.

Bei den beiden oben beschriebenen Verpackungsvorgängen wird zum Formen der Preßlinge 2 nur jeweils der Stempel 14 verwendet, während der andere Stempel 13 als Gegenlager wirkt. Besonders gleichmäßige und auch hohe Verdichtungen lassen sich erzielen, wenn beide Stempel 13, 14 zum Formen des Preßlings 2 gegeneinander verfahren werden.In the two packaging processes described above to form the compacts 2 only the stamp 14 used while the other stamp 13 as a counter bearing works. Particularly uniform and also high compaction can be achieved if both stamps 13, 14 for molding of the compact 2 can be moved against each other.

Bei den Verpackungsvorgängen ist grundsätzlich der Hohlraum der Matritze 12 und der Preßabstand der beiden Stempel 13, 14 an die Endform der Packung 4 anzupassen. Hat die gewünschte Packung 4 die Form eines Quaders, wie größtenteils üblich, haben der Hohlraum der Matritze 12 und die beiden Stempel 13, 14 einen rechteckigen Querschnitt. Beim Ausführungsbeispiel nach Figur 1 wir die Höhe der Packung 4 durch den Abstand der beiden Stempel 13, 14 bei Preßende bestimmt. Der Querschnitt der Packung 4 entspricht dem Querschnitt des Hohlraums der Matritze 12. Dagegen bestimmen die beiden Abmessungen des Querschnitts der Matritze 12 die Tiefe und die Breite des nach dem Verschließen senkrecht aufgestellten Beutels 3 und der Preßabstand der beiden Stempel 13, 14 die Höhe der Packung 4, bei der der Verschluß oben ist.In the packaging process, the cavity is basically the die 12 and the press distance of the two punches 13, 14 to adapt to the final shape of the package 4. Has the desired pack 4 the shape of a cuboid, such as mostly common, have the cavity of the die 12 and the two stamps 13, 14 have a rectangular cross section. In the embodiment of Figure 1 we the height of Pack 4 by the distance between the two stamps 13, 14 at Press end determined. The cross section of the pack 4 corresponds the cross section of the cavity of the die 12. On the other hand determine the two dimensions of the cross section of the Die 12 the depth and width of the after Seal vertically placed bag 3 and the Press distance of the two stamps 13, 14 the height of the pack 4, with the closure on top.

Zum leichten Einführen des Preßlings 2 in einen Beutel 3 sind die Querschnittsabmessungen des Beutels 3 wenig größer als die entsprechenden Abmessungen des Preßlings 2, so daß beim Einschieben des Preßlings 2 in den Beutel 3 genügend Spiel vorhanden ist.For easy insertion of the compact 2 into a bag 3 the cross-sectional dimensions of the bag 3 are slightly larger than the corresponding dimensions of the compact 2, so that enough when inserting the compact 2 into the bag 3 Game exists.

Um das Einführen des Preßlings 2 in den Beutel 3 zusätzlich zu erleichtern kann gemäß Figur 3 eine spezielle Einrichtung 15 zum Offenhalten des Kopfbereiches eines Beutels 3 verwendet werden. Diese Einrichtung 15 weist einen vorzugsweise umlaufenden Rahmen 16 mit dem Kopfbereich des Beutels 3 zugewandten Saugöffnungen 17 auf, die mit einer Vakuumleitung 18 verbunden sind. Zumindest während des Einschiebens des Preßlings 2 in den Beutel 3 läßt sich so der Kopfbereich des Beutels 3 offenhalten, so daß nur ein Minimum an Spiel des Preßlings 2 in bezug auf den Beutel 3 erforderlich ist.To insert the compact 2 in the bag 3 additionally According to FIG. 3, a special device can facilitate this 15 for keeping the head region of a bag 3 open be used. This device 15 has one preferably circumferential frame 16 with the head region of the Bag 3 facing suction openings 17 with a Vacuum line 18 are connected. At least during the Pushing the compact 2 into the bag 3 can be so keep the head area of the bag 3 open so that only one Minimum play of the compact 2 with respect to the bag 3 is required.

Um darüber hinaus eine Beschädigung des Preßlings 2 beim Überschieben aus der Matrize 12 in den Beutel 3 zu verhindern weist gemäß Figur 4 die dem Beutel 3 zugewandte Seite der Matrize 12 an deren Innenkante eine Schräge 19 auf. Diese Schräge 19, deren Winkel etwa ein bis drei Grad beträgt, verhindert Abbrechungen des Preßlings 2 beim Ausschieben aus der Matrize 12.In addition, damage to the compact 2 when Slide from the die 12 into the bag 3 prevent according to Figure 4 facing the bag 3 Side of the die 12 on the inner edge of a slope 19 on. This bevel 19, the angle of which is about one to three degrees is, prevents breakage of the compact 2 when Eject from the die 12.

Diese Abbrechungen können auch vermieden werden, wenn entsprechend der Figuren 5a und 5b modifizierte Matrizen 12a, 12b verwendet werden. Diese Matrizen 12a, 12b sind zwei- bzw. vierteilig ausgebildet. Deren Gehäuseteile 21 und 22, bzw. 23 bis 26 werden zum Pressen gegeneinander gefahren, so daß sie eine dichte Aufnahme für das Schüttgut 1 ausbilden. Nach dem Formen des Preßlings 2 können sie zu dessen Entnahme auseinander gefahren werden.These cancellations can also be avoided if Modified matrices according to FIGS. 5a and 5b 12a, 12b can be used. These matrices 12a, 12b are formed in two or four parts. The housing parts 21 and 22, or 23 to 26 are pressed against each other driven so that they are a tight receptacle for the bulk material 1 train. After molding the compact 2, you can its removal be moved apart.

Um bei sauerstoffempfindlichen Schüttgütern, beispielsweise Kaffee, einen Aromaschutz zu gewährleisten, können die beschriebenen Verpackungsvorgänge in einer Schutzgasatmosphäre durchgeführt werden, so daß das verpackte Gut von der Umgebungsluft, insbesondere von deren Sauerstoffgehalt geschützt ist und in der gasdicht verschlossenen Verpackung bis zum Verbrauch geschützt bleibt. In the case of bulk materials sensitive to oxygen, for example Coffee can ensure aroma protection described packaging processes in one Protective gas atmosphere can be carried out so that the Packaged goods from the ambient air, especially from their Oxygen content is protected and in the gastight sealed packaging protected until consumption remains.

Umverpackungen für die Preßlinge 2 können auch die Form von Schlauchbeuteln, Bechern, Dosen, Gläsern oder Röhrchen aus Kunststoff oder Metall oder dergleichen haben. Die Gestalt eines Preßlings 2 ist jeweils der Form der gewählten Verpackung anzupassen bzw. umgekehrt.Outer packaging for the compacts 2 can also take the form of Tubular bags, mugs, cans, glasses or tubes Have plastic or metal or the like. The shape a compact 2 is the shape of the selected one Adapt packaging or vice versa.

Ein Preßling 2 kann die Gestalt, wie oben beschrieben, eines Quaders oder Würfels, oder auch andere Formen wie beispielsweise die eines Zylinders, einer Kugel und dergleichen gängigen geometrischen Körpern haben. Auch ist es denkbar, den Preßling 2 zur Schonung seiner Kanten und zum einfacheren Einführen in seine Umverpackung mit Schrägen oder gerundeten Kanten auszubilden. Auch kissenförmig ausgebildete Preßlinge 2 können je nach Anwendungsfall vorteilhaft sein.A compact 2 can have the shape as described above Cuboids or cubes, or other shapes such as for example that of a cylinder, a sphere and have such common geometrical bodies. It is also conceivable to protect the compact 2 Edges and for easier insertion into its outer packaging with slopes or rounded edges. Also pillow-shaped compacts 2 can depending on Use case to be advantageous.

Damit beim Einführen eines Preßlings 2 in die Verpackung, beispielsweise einen Beutel 3, die Luft oder das Gas aus dem Beutel 3 schnell entweichen kann, können im Umfang des Preßlings 2 Strömungskanäle 6 und am vorauslaufenden Ende Schrägen 7 angeordnet werden (Figur 6). Zusätzlich kann in einer Seite des Preßlings 2 eine Aussparung oder eine Tasche 8 angeordnet werden, in die nach dem Kontrollwiegen des Preßlings 2 eine dem Fehlgewicht entsprechende Menge an Schüttgut einbringbar ist.So that when a compact 2 is introduced into the packaging, for example a bag 3, the air or the gas from the Bag 3 can escape quickly, the extent of Pressed 2 flow channels 6 and at the leading end Slopes 7 are arranged (Figure 6). In addition, in one side of the compact 2, a recess or a pocket 8 are arranged, in which after the check weighing of the Press 2 a quantity corresponding to the defective weight Bulk material can be introduced.

Um aus der Verpackung leicht Einzelportionen entnehmen zu können wird der Preßling 2 in der Umverpackung vor oder nach deren Verschließen durch Zerstören der Haftung zwischen den einzelnen Körnern wieder gelockert werden, ohne daß das Volumen, und insbesondere die Höhe der Verpackung beachtenswert zunimmt. Das Volumen der Verpackung soll dazu jedoch etwas größer sein als das Blockvolumen des Preßlings. Das Lockern wird durchgeführt, indem die Packung 4 mit dem Preßling 2 zwischen zwei Platten eingespannt und kurzzeitig ein- oder mehrmals, vorzugsweise in einer quer zur vorhergehenden Preßrichtung verlaufenden Richtung, gepreßt wird. Möglich ist auch die Beschallung des Preßlings 2 mit Ultraschall oder auch die Kombination von Pressen und Ultraschall. Auch kann das Lockern der Körner mittels Vibration der Packung 4 oder einer Kombination von Vibration in Verbindung mit Pressen und/oder Ultraschall erfolgen.To easily take individual portions from the packaging can the compact 2 in the outer packaging before or after closing them by destroying the liability between the individual grains are loosened again without the Volume, and in particular the amount of packaging remarkably increases. The volume of the packaging should do this however, be slightly larger than the block volume of the compact. Loosening is carried out by packing 4 with the Compact 2 clamped between two plates and briefly one or more times, preferably in a cross to previous pressing direction extending direction, pressed becomes. It is also possible to sonicate the compact 2 with Ultrasound or the combination of presses and Ultrasonic. The grains can also be loosened by means of Vibration of package 4 or a combination of vibrations in connection with presses and / or ultrasound.

Der beschriebene Lockerungsvorgang der Körner kann bei einer noch geöffneten Packung 4 mittels einer in die Packung einbringbaren Platte 27 erfolgen. Gemäß der Figur 7 läßt sich ein einfaches Einführen der Platte 27 in die Packung 4 erzielen, wenn ein mit der Platte 27 verbundener Einführstempel 28 kleiner ausgebildet ist als die Platte 27, die dem Öffnungsquerschnitt der Packung 4 angepasst sein muß. Auch kann der Einführstempel 28 beim Einführen in die Packung 4 zuerst eine Schwenkbewegung ausführen, damit er in einer ersten Phase einen geringeren Einführquerschnitt aufweist (Figur 8). Das anschließende Lockern erfolgt dann mit parallel geführtem Einführstempel 28.The described loosening process of the grains can occur with a still open pack 4 by means of a in the pack insertable plate 27 take place. According to FIG. 7 easy insertion of the plate 27 into the package 4 achieve when a connected to the plate 27 Insertion punch 28 is made smaller than the plate 27, which are adapted to the opening cross section of the pack 4 got to. The insertion punch 28 can also be inserted into the Pack 4 first swivel so that it is in a first phase a smaller insertion cross-section has (Figure 8). The subsequent loosening then takes place with parallel entry stamp 28.

Es hat sich gezeigt, daß das Lockern vereinfacht wird, bzw. eine geringere Kraft erfordert, wenn die dem Preßling 2 zugewandte Seite der Platte 27 nicht eben, sondern strukturiert ausgebildet ist. Diese Strukturen sind bevorzugt in Form von Keilen ausgebildet, deren Anordnung verschiedene Muster haben kann.It has been shown that loosening is simplified, or a lower force is required if the compact 2 facing side of the plate 27 not flat, but is structured. These structures are preferably in the form of wedges trained, the arrangement of which can have different patterns.
