Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Beuteln aus Bandmaterial und zum Abfüllen derselben mit einem Füllgut, wobei das Bandmaterial zwischen zwei rotierende Siegelwalzen geführt wird und mit diesen zunächst der Bodenrand und die Seitenränder gesiegelt werden, während das Füllgut aus einem Füllgutbehälter dosiert und in die so gebildete Tasche eingefüllt wird, worauf der obere Rand und damit der Beutel geschlossen, vom Bandmaterial getrennt und weggeführt wird, und eine Maschine zur Durchführung des Verfahrens. The invention relates to a method for producing bags from band material and for filling them with a filling material, the band material being guided between two rotating sealing rollers and first sealing the bottom edge and the side edges, while metering the filling material from a filling material container and into it bag thus formed is filled, whereupon the upper edge and thus the bag is closed, separated from the strip material and carried away, and a machine for performing the method.
Das Herstellen und Abfüllen von Beuteln mit einem Füllgut, z.B. einem Granulat oder einem körnigen Gut, wird automatisch durchgeführt. Hierzu werden Maschinen eingesetzt, die zwar in den Einzelheiten unterschiedlich ausgebildet sind, jedoch das Bilden der Beutel und das Abfüllen derselben mit einer dosierten Menge in ähnlicher Weise durchführen. Die Beutel werden hierbei aus einem Folienmaterial fortlaufend von einer Rolle abgewickelt, worauf in einer Schneid- und Faltstation zwei nebeneinanderlaufende Bänder hergestellt werden, die in die Siegelstation zwischen zwei rotierende Siegelwalzen geführt werden. Die beiden nebeneinanderlaufenden Bänder können jedoch auch durch Abwickeln von zwei Rollen gebildet werden. Die beiden Siegelwalzen ziehen das für die Beutelbildung benötigte Material von der Rolle bzw. den Rollen ab und siegeln die beiden Bänder am Bodenrand und an den Seitenrändern des zu bildenden Beutels. Gleichzeitig wird in die so gebildete The manufacture and filling of bags with a filling material, e.g. a granulate or a granular good is carried out automatically. For this purpose, machines are used which are designed differently in the details, but carry out the forming of the bags and the filling of them with a metered amount in a similar manner. The bags are continuously unwound from a roll from a film material, whereupon two adjacent belts are produced in a cutting and folding station and are guided into the sealing station between two rotating sealing rollers. However, the two belts running side by side can also be formed by unwinding two rolls. The two sealing rollers pull the material required for the bag formation from the roll or rolls and seal the two bands on the bottom edge and on the side edges of the bag to be formed. At the same time it is formed in the way
Tasche eine dosierte Menge des Füllgutes eingefüllt, worauf beim Weiterlaufen der Bänder auch der obere Rand gesiegelt wird. Für die Dosierung wird beispielsweise eine Kammer- oder Schneckendosierung vorgesehen. Nach dem Verschliessen des Beutels wird dersel-5 be durch Führungsrollen zu einer rotierenden Schneideinrichtung transportiert, wo das Band in die einzelnen Beutel getrennt wird. Bag filled a metered amount of the contents, whereupon the upper edge is sealed as the belts continue to run. For example, chamber or screw metering is provided for metering. After the bag has been closed, it is transported by guide rollers to a rotating cutting device, where the tape is separated into the individual bags.
Damit die Heissiegelung durch die beiden Siegelwalzen zuverläs-" sig erfolgt, ist es erforderlich, dass der Abstand zwischen den beiden Walzen exakt eingestellt ist. Sollen Beutel unterschiedlicher Grösse io hergestellt werden, können Walzen mit unterschiedlich angeordneten Siegelstegen vorgesehen werden, so dass beispielsweise zwei oder mehr Beutel hergestellt werden können. Nachteilig ist jedoch, dass die Beutel nicht in beliebiger Grösse, sondern nur in bestimmten, So that the heat sealing by the two sealing rollers takes place reliably, it is necessary that the distance between the two rollers is set precisely. If bags of different sizes are to be produced, rollers with differently arranged sealing bars can be provided, so that, for example, two or more bags can be produced, but the disadvantage is that the bags are not of any size, but only in certain,
sich aus dem Umfang der Siegelwalzen ergebenden Grössen herge-15 stellt werden können. 15 resulting from the size of the sealing rollers can be produced.
Hier setzt die Erfindung ein, der die Aufgabe zugrunde liegt, das Verfahren und die Maschine der eingangs beschriebenen Art so auszugestalten, dass Beutel beliebiger Grösse und in einem verhältnismässig grossen Bereich hergestellt werden können. This is where the invention comes in, which is based on the object of designing the method and the machine of the type described at the outset in such a way that bags of any size and in a relatively large range can be produced.
20 Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass zur Herstellung einer anderen Beutelgrösse der Abstand der Drehachsen der Siegelwalzen geändert wird und die Siegelwalzen durch • zwei andere, entsprechend passende Siegelwalzen ersetzt werden. 20 This object is achieved according to the invention in that, in order to produce a different bag size, the distance between the axes of rotation of the sealing rollers is changed and the sealing rollers are replaced by • two other, correspondingly suitable sealing rollers.
Die erfindungsgemässe Maschine zur Durchführung des Verfah-25 rens kennzeichnet sich dadurch, dass die Wellen der beiden Siegelwalzen in je einem Paar Lagerböcken drehbar gelagert sind, die quer zu diesen Wellen verschiebbar geführt sind. The machine according to the invention for carrying out the method is characterized in that the shafts of the two sealing rollers are each rotatably mounted in a pair of bearing blocks which are guided so as to be displaceable transversely to these shafts.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt und nachfolgend beschrieben. Es zeigen: The invention is shown in the drawing in one embodiment and described below. Show it:

Fig. 1 zeigt eine Maschine zum Herstellen von Beuteln und zum dosierten Abfüllen derselben. Die Maschine weist ein auf einem Sockel 1 abgestütztes Gehäuse 2 auf, in dem der Antrieb für die einzelnen Elemente und die Steuerung untergebracht sind. Diese Ele-40 mente umfassen einen Füllgutbehälter 3 mit einer Dösiervorrichtung 4, eine Siegelstation 5 mit einer Schneidvorrichtung 6, eine Vorratsrolle 7 mit einem bandförmigen siegelfähigen Material und einen Ableitungskanal 8 mit einer schwenkbaren Weiche 9. Fig. 1 shows a machine for the manufacture of bags and for the metered filling of the same. The machine has a housing 2 supported on a base 1, in which the drive for the individual elements and the control are accommodated. These elements comprise a product container 3 with a dosing device 4, a sealing station 5 with a cutting device 6, a supply roll 7 with a band-shaped sealable material and a discharge channel 8 with a pivotable switch 9.
In Fig. 2 und 3 ist die Siegelstation 5 mit ihren Einzelheiten dar-45 gestellt. Die Siegelstation 5 weist zwei Siegel walzen 10 auf, von denen in Fig. 3 nur eine Walze dargestellt ist und die auf einer Welle 2 and 3, the sealing station 5 is shown with its details. The sealing station 5 has two sealing rollers 10, of which only one roller is shown in Fig. 3 and on a shaft
11 gelagert sind. Die Siegelwalzen 10 weisen eine Anzahl Siegelstege 11 are stored. The sealing rollers 10 have a number of sealing webs
12 auf, die durch eine eingebaute Heizung auf Siegeltemperatur gebracht werden, so dass sie die Beutelränder siegeln können. 12, which are brought to sealing temperature by a built-in heater so that they can seal the edges of the bag.
50 Von der Vorratsrolle 7 wird das bandförmige Material 13 abgewickelt und zu einer nicht näher dargestellten Schneid- und Faltvorrichtung geführt, wo es zu zwei aufeinanderliegenden Bändern 15,16 ausgerichtet und zwischen die Siegelwalzen 10 geführt wird. In Fig. 3 sind mit 14 schematisch Teile der Schneid- und Faltvorrich-55 tung dargestellt. 50 From the supply roll 7, the band-shaped material 13 is unwound and guided to a cutting and folding device (not shown in more detail), where it is aligned with two bands 15, 16 lying on top of one another and is guided between the sealing rollers 10. In Fig. 3, 14 schematically shows parts of the cutting and folding device 55.
In Fig. 2 ist der Umriss von zwei verschiedenen Siegelwalzen 10 dargestellt. Der mit einem Doppelpfeil bezeichnete Abstand zwischen den Drehachsen 17 dieser beiden Siegelwalzengrössen ist der Abstandsbereich 18, innerhalb welchem die beiden Wellen 11 der 60 Siegelwalzen 10 verstellt und mit anderen Siegelwalzen versehen werden können, um beliebige Formate der Beutel 19 herzustellen. 2 shows the outline of two different sealing rollers 10. The distance between the axes of rotation 17 of these two sealing roller sizes, indicated by a double arrow, is the distance range 18 within which the two shafts 11 of the 60 sealing rollers 10 can be adjusted and provided with other sealing rollers in order to produce any formats of the bags 19.
Jede der beiden Siegelwalzenwellen 11 ist in zwei Lagerböcken 20, 21 mittels Wälzlagern 22 gelagert. Die Lagerböcke 20, 21 sind auf Führungswellen 23 verschiebbar gelagert und können durch eine 65 mittels eines Handrades 24 verstellbare Spindel 25 verstellt werden. Die Spindel 25 weist hierzu zwei gegenläufige Gewinde 26 mit je einer Spindelmutter 27 auf. Der Lagerbock 20, 21 umgreift das Spindelgewinde 26 und bildet eine Ausnehmung 28, in der die Spindel- Each of the two sealing roller shafts 11 is supported in two bearing blocks 20, 21 by means of roller bearings 22. The bearing blocks 20, 21 are slidably mounted on guide shafts 23 and can be adjusted by a spindle 25 which can be adjusted by means of a handwheel 24. For this purpose, the spindle 25 has two opposing threads 26, each with a spindle nut 27. The bearing block 20, 21 engages around the spindle thread 26 and forms a recess 28 in which the spindle

mutter 27 liegt. Wird mit dem Handrad 24 die Spindel 25 gedreht, bewegen sich die Spindelmuttern 27 und damit die Lagerböcke 20, 21 gegeneinander oder auseinander. mother 27 lies. If the spindle 25 is rotated with the handwheel 24, the spindle nuts 27 and thus the bearing blocks 20, 21 move against one another or apart.
Die Siegelwalzenwellen 11 werden über eine gemeinsame Antriebswelle 29 angetrieben. Auf der Antriebswelle 29 sind zwei ge- 5 genläufige Schnecken 30 angeordnet, in die je ein auf der Welle 11 sitzendes Schneckenrad 31 eingreift. Die Antriebswelle 29 wird in nicht dargestellter Weise durch einen im Gehäuse 2 angeordneten Antrieb angetrieben. Die Antriebswelle 29, die Schneckengetriebe 30, 31 und die Lagerböcke 20, 21 mit den Wellen 11 sind in einem 10 Gehäuse 32 eingebaut, das an der Vorderwand 33 des Gehäuses 2 befestigt ist. The sealing roller shafts 11 are driven by a common drive shaft 29. Arranged on the drive shaft 29 are two counter-rotating screws 30, each of which engages with a worm wheel 31 seated on the shaft 11. The drive shaft 29 is driven in a manner not shown by a drive arranged in the housing 2. The drive shaft 29, the worm gear 30, 31 and the bearing blocks 20, 21 with the shafts 11 are installed in a housing 32 which is fastened to the front wall 33 of the housing 2.
Damit die Lagerböcke 20, 21 jeder Welle 11 zusammen verstellt werden können, ist die Spindel 25 mit der Spindel 25' der Lager- ]5 böcke 20, 21 mittels eines Hülltriebes 34, z.B. eines Kettentriebes, verbunden. So that the bearing blocks 20, 21 of each shaft 11 can be adjusted together, the spindle 25 with the spindle 25 'of the bearing] 5 blocks 20, 21 by means of an enveloping drive 34, e.g. a chain drive connected.
Die durch die Siegelwalzen 10 gesiegelten Beutel 19 bewegen sich abwärts durch eine rotierende Vorschubvorrichtung 35, deren Walzen 36 durch einen Hülltrieb 37 von der Welle 11 aus angetrie- 20 ben werden. Anschliessend wird das aus gesiegelten Beuteln 19 bestehende Band durch eine Schneidvorrichtung 38 in die einzelnen Beutel getrennt. Die geschnittenen Beutel 19 fallen in den Ableitungskanal 8 und können am Ende desselben gesammelt und verpackt werden. The bags 19 sealed by the sealing rollers 10 move downwards through a rotating feed device 35, the rollers 36 of which are driven from the shaft 11 by an enveloping drive 37. The band consisting of sealed bags 19 is then separated into the individual bags by a cutting device 38. The cut bags 19 fall into the discharge channel 8 and can be collected and packed at the end of the same.
Die Einstellung verschiedener Beuteigrössen kann ohne Schwierigkeit und problemlos durchgeführt werden. Zunächst werden die Siegelwalzen 10 entfernt und durch andere Siegel walzen ersetzt, worauf durch Drehen des Handrades 24 der Abstand der Drehachsen 17 der Wellen 11 so lange verändert wird, bis die Siegelwalzen 10 sich in derjenigen Lage befinden, in welcher sie die beiden aufeinan-derliegenden Bänder 15, 16 zusammenpressen und siegeln können. Wesentliche ist hierbei, dass die Spindelmuttern 27 selbsthemmend sind und praktisch spielfrei in den Ausnehmungen 28 liegen, so dass sich der Abstand zwischen den Drehachsen 17 während des Betriebes nicht ändert. Different sizes of prey can be set easily and without difficulty. First, the sealing rollers 10 are removed and replaced by other sealing rollers, whereupon the distance between the axes of rotation 17 of the shafts 11 is changed by turning the handwheel 24 until the sealing rollers 10 are in the position in which they lie on top of each other Belts 15, 16 can be pressed together and sealed. It is essential here that the spindle nuts 27 are self-locking and lie practically free of play in the recesses 28, so that the distance between the axes of rotation 17 does not change during operation.
Der Antrieb der Siegelwalzen 10 kann etwas vereinfacht werden, wenn die Spindel 25 anstelle der unteren Führungswellen 23 gleichzeitig auch als Führungswelle benützt wird. Dadurch wird erreicht, dass der Abstand der Spindelmutter 27 von der Drehachse 17 der Siegelwalzenwellen 11 kleiner wird und dadurch günstigere Kraftangriffsverhältnisse bewirkt. The drive of the sealing rollers 10 can be somewhat simplified if the spindle 25 is also used as a guide shaft instead of the lower guide shafts 23. It is thereby achieved that the distance of the spindle nut 27 from the axis of rotation 17 of the sealing roller shafts 11 becomes smaller and thereby causes more favorable force application conditions.
