Description
Verfahren und Maschine zum Herstellen und Method and machine for manufacturing and
Abfüllen von Beuteln 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. Filling of bags The invention relates to a method of manufacture of bags made of strip material and for filling the same with a filling material, wherein the strip material is guided between two rotating sealing rollers and with them First the bottom edge and the side edges are sealed while the filling material is dosed from a product container and filled into the pocket formed in this way, whereupon the upper edge and thus the bag closed, separated from the band material and is 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 nebeneinander laufenden 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 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 derselbe durch Führungsrollen zu einer rotierenden Schneideinrichtung transportiert, wo das Band in die einzelnen Beutel getrennt wird.The production and filling of bags with a filling material, e.g. a Granules, or a granular product, is carried out automatically. Machines are used for this used, which are designed differently in the details, however forming the bags and filling them with a metered amount in the same way Way to perform. The bags are made continuously from a film material unwound from a roll, whereupon two side by side in a cutting and folding station Ribbons are made that go into the sealing station between two rotating sealing rollers be guided. However, the two belts running next to each other can also go through Unwinding can be formed by two rolls. The two sealing rollers pull that for the bag formation required material from the roll or the roll off and seal the two ribbons on the bottom edge and on the side edges of the to be formed Bag. At the same time, a metered amount of the filling material is put into the pocket formed in this way filled in, whereupon the upper edge is sealed as the tapes continue to run. For example, a chamber or screw metering system is provided for metering. After the bag has been closed, guide rollers turn it into a rotating one Cutting device transported where the tape is cut into individual bags.
Damit die Heissiegelung durch die beiden Siegelwalzen zuverlässig erfolgt, ist es erforderlich, dass der Abstand zwischen den beiden Walzen exakt eingestellt ist. Sollen Beutel unterschiedlicher Grösse 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, sich aus dem Umfang der Siegelwalzen ergebenden Grössen hergestellt werden können.So that the heat sealing by the two sealing rollers is reliable occurs, it is necessary that the distance between the two rollers is exact is set. If bags of different sizes are to be produced, Rollers with differently arranged sealing bars are provided so that for example two or more bags can be made. However, it is disadvantageous that the bags do not come in any size, but only in certain sizes the sizes resulting from the circumference of the sealing rollers can be produced.
Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, 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 on which the object is based, the method, comes in and to design the machine of the type described at the outset so that any bag Size and can be produced in a relatively large area.
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.This object is achieved according to the invention in that for the production Another bag size changed the distance between the axes of rotation of the sealing rollers and the sealing rollers by two other, appropriately matching sealing rollers be replaced.
Die erfindungsgemässe Maschine zur Durchführung des Verfahrens 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 in a pair of bearing blocks are rotatably mounted, which are guided displaceably transversely to these shafts.

In Fig. 2 und 3 ist die Siegelstation 5 mit ihren Einzelheiten dargestellt. Die Siegelstation 5 weist zwei Siegelwalzen 10 auf, von denen in Fig. 3 nur eine Walze dargestellt ist und die auf einer Welle 11 gelagert sind. Die Siegelwalzen 10 weisen eine Anzahl Siegelstege 12 auf, die durch eine eingebaute Heizung auf Siegeltemperatur gebracht werden, so dass sie die Beutelränder siegeln können.In Fig. 2 and 3, the sealing station 5 is shown with its details. The sealing station 5 has two sealing rollers 10, only one of which in FIG. 3 Roller is shown and which are mounted on a shaft 11. the Sealing rollers 10 have a number of sealing webs 12, which are provided by a built-in heater Sealing temperature are brought so that they can seal the edges of the bag.
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 Faltvorrichtung dargestellt.The strip-shaped material 13 is unwound from the supply roll 7 and led to a cutting and folding device, not shown, where it aligned to two superposed belts 15, 16 and between the sealing rollers 10 is performed.

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 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 Spindelmutter 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.Each of the two sealing roller shafts 11 is in two bearing blocks 20, 21 mounted by means of roller bearings 22. The bearing blocks 20, 21 are on guide shafts 23 slidably mounted and can be adjusted by means of a handwheel 24 Spindle 25 can be adjusted. For this purpose, the spindle 25 has two threads running in opposite directions 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 nut 27 lies. Will come with the Handwheel 24 rotates the spindle 25, the spindle nuts 27 and thus move the bearing blocks 20, 21 against each other or apart.
Die Siegelwalzenwellen 11 werden über eine gemeinsame Antriebswelle 29 angetrieben. Auf der Antriebswelle 29 sind zwei gegenläufige 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 Gehäuse 32 eingebaut, das an der Vorderwand 33 des Gehäuses 2 befestigt ist.The sealing roller shafts 11 are via a common drive shaft 29 powered. On the drive shaft 29 two counter-rotating screws 30 are arranged, in the ever one worm wheel 31 seated on shaft 11 engages. The drive shaft 29 is in a manner not shown by a in the housing 2 arranged drive driven. 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 attached 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 Lagerböcke 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 can, the spindle 25 with the spindle 25 'of the bearing blocks 20, 21 by means of a Shell drive 34, e.g. of 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 angetrieben 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 downward by a rotating feed device 35, the rollers 36 of which by a casing drive 37 are driven by the shaft 11. Then the sealed Bags 19 existing tape through a cutting device 38 into the individual bags separated. The cut bags 19 fall into the discharge channel 8 and can collected and packaged at the end of the same.
Die Einstellung verschiedener Beutelgrössen kann ohne Schwierigkeit und problemlos durchgeführt werden. Zunächst werden die Siegelwalzen 10 entfernt und durch andere Siegelwalzen ersetzt, worauf durch Drehen des Handrades 24 der Abstand der Drehachsen 17 der Wellen 11 solange verändert wird, bis die Siegelwalzen 10 sich in derjenigen Lage befinden, in welcher sie die beiden aufeinanderliegenden Bänder 15, 16 zusammenpressen und siegeln können. Wesentlich 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.The setting of different bag sizes can be done without difficulty and can be carried out without any problems. First, the sealing rollers 10 are removed and replaced by other sealing rollers, whereupon by turning the handwheel 24 of the The distance between the axes of rotation 17 of the shafts 11 is changed until the sealing rollers 10 are in the position in which they lie on top of each other Straps 15, 16 can be compressed and sealed. It is essential that the Spindle nuts 27 are self-locking and practically free of play in the recesses 28 lie so that the distance between the axes of rotation 17 during operation does not change.
Der Antrieb der Siegelwalzen 10 kann etwas vereinfacht werden, wenn die Spindel 25 anstelle der unteren Führungswellen 23 gleichzeitig auch als Führungswelle benützt wird.The drive of the sealing rollers 10 can be simplified somewhat if the spindle 25 instead of the lower guide shafts 23 at the same time as a guide shaft is used.
Dadurch wird erreicht, dass der Abstand der Spindelmutter 27 von der Drehachse 17 der Siegelwalzenwellen 11 kleiner wird und dadurch günstigere Kraftangriffsverhältnisse bewirkt.This ensures that the distance between the spindle nut 27 and the The axis of rotation 17 of the sealing roller shafts 11 becomes smaller and, as a result, more favorable force application conditions causes.
