Description

Die Erfindung betrifft eine Maschine zum Herstellen, Füllen und Verschließen von Packungen, bei der aus einer flexiblen Materialbahn geformte und verschweißte Pakkungshüllen gefüllt und verschlossen werden, mit einem Spreizdornkarussell und mit mindestens einem nachgeordneten Füllkarussell mit einer Füllstation und einer Kopfnahtschweißstation.The invention relates to a machine for producing, filling and closing packs, in which packaging sleeves formed and welded from a flexible material web are filled and closed, with an expanding mandrel carousel and with at least one downstream filling carousel with a filling station and a head seam welding station.

Derartige Maschinen dienen in den meisten Fällen zur Herstellung von Flüssigkeitspackungen, beispielsweise für Milch, Saft und dergleichen. Die Materialbahn, beispielsweise kunststoffbeschichtetes Papier, wird von einer Vorratsrolle abgezogen. Daraus werden die einzelnen Packungshüllen durch Abschneiden und Verschweißen hergestellt. Dazu werden die Packungshüllen jeweils auf Spreizdorne eines Spreizdornkarussells aufgenommen.Such machines are used in most cases for the production of liquid packs, for example for milk, juice and the like. The material web, for example plastic-coated paper, is drawn off from a supply roll. The individual packaging casings are made from this by cutting and welding. For this purpose, the packaging sleeves each on expanding mandrels of an expanding mandrel carousel.

Bei einer bekannten Maschine der eingangs genannten Art (US-PS 3 918 236) werden die so geformten Packungshüllen, die nur noch oben offen sind, abwechselnd an zwei nachgeordnete Füllkarussells übergeben, auf denen die Packungshüllen in einer Füllstation gefüllt und in einer Kopfnahtschweißstation verschlossen werden.In a known machine of the type mentioned at the outset (US Pat. No. 3,918,236), the packaging sleeves shaped in this way, which are only open at the top, are alternately transferred to two downstream filling carousels, on which the packaging sleeves are filled in a filling station and sealed in a head seam welding station .

Wenn quaderförmiger Packungen hergestellt werden, entstehen am Boden und am Kopf der Packung jeweils zwei Laschen. Damit diese Bodenlaschen bzw. Kopflaschen bei der anschließenden Aufnahme der gefüllten Packungen in einer Verpackung, beispielsweise einem Karton, nicht stören, müssen diese Laschen entweder flach an die Packungsaußenseite angelegt oder abgeschnitten werden. Das Abschneiden der Laschen ist nur möglich, wenn die Packungshülle an dieser Stelle so verschweißt ist, daß durch das Abschneiden der Laschen keine Öffnung entsteht. Ein solcher zusätzlicher Schweißvorgang ist verhältnismäßig aufwendig. Das einfache Andrücken der Bodenlaschen und Kopflaschen genügt nicht, um diese Laschen in die für das nachfolgende Verpacken geeignete Stellung zu bringen.When cuboid packs are produced, two tabs are created on the bottom and on the top of the pack. So that these bottom flaps or top flaps do not interfere with the subsequent inclusion of the filled packs in a packaging, for example a cardboard box, these flaps must either be laid flat on the outside of the pack or cut off. The tabs can only be cut off if the packing sleeve is welded at this point in such a way that no opening is created by cutting off the tabs. Such an additional welding process is relatively complex. Simply pressing the bottom flaps and top flaps is not enough to bring these flaps into the position suitable for subsequent packaging.

Aufgabe der Erfindung ist es daher, eine Maschine der eingangs genannten Art so auszubilden, daß eine bleibende Anlage der Bodenlaschen und Kopflaschen an der Packungsaußenseite erreicht wird; die hierfür erforderlichen zusätzlichen Arbeitsstationen sollen in möglichst raumsparender Weise an der Maschine angeordnet und konstruktiv möglichst einfach ausgeführt sein.The object of the invention is therefore to design a machine of the type mentioned at the outset in such a way that a permanent contact of the bottom flaps and top flaps on the outside of the pack is achieved; the additional workstations required for this should be arranged on the machine in a space-saving manner and should be constructive be as simple as possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Spreizdornkarussell eine Bodenlaschenformstation angeordnet ist, daß die Kopfnahtschweißstation über die gesamte Länge der Kopfnaht reichende Schweißbacken aufweist,und daß dem Füllkarussell ein Kopfformkarussell nachgeordnet ist, das eine Kopflaschenformstation und eine Kopflaschensiegelstation aufweist.This object is achieved in that a bottom flap forming station is arranged on the expanding mandrel carousel, that the head seam welding station has welding jaws extending over the entire length of the head seam, and that the filling carousel is followed by a head shaping carousel which has a top flap shaping station and a top flap sealing station.

Die Bodenlaschen und die Kopflaschen werden in der jeweiligen Formstation so vorgeformt, daß sie in der nachfolgenden Siegelstation in einfacher Weise an der Packungsaußenseite mittels Druck- und Wärmeeinwirkung angesiegelt werden können. Durch die Vorformung werden die an der Siegelstelle auftretenden Kräfte sehr klein gehalten; dadurch besteht keine Gefahr, daß sich die Siegelverbindung wieder löst; andererseits sind die Festigkeitsanforderungen an die Siegelverbindung dadurch gering.The bottom flaps and the top flaps are preformed in the respective molding station in such a way that they can be easily sealed on the outside of the package in the subsequent sealing station by means of pressure and heat. Due to the preforming, the forces occurring at the sealing point are kept very small; this means that there is no danger that the sealing connection will come loose again; on the other hand, the strength requirements for the sealed connection are low as a result.

Die größere Anzahl von Bearbeitungsstationen wird in konstruktiv sehr einfacher und raumsparender Weise dadurch geschaffen, daß die Stationen zum Formen und Siegeln der Kopflaschen in ein gesondertes Kopfformkarussell verlegt wurden. Gegenüber der Möglichkeit, ein größeres Karussell mit mehr Bearbeitungsstationen vorzusehen, hat diese Lösung den Vorteil besserer Raumausnutzung. Konstruktiv ist die Lösung deshalb besonders einfach, weil für das Kopfformkarussell in wesentlichem Umfang die gleichen Bauteile verwendet werden können wie für das Füllkarussell.The greater number of processing stations is created in a structurally very simple and space-saving manner by the fact that the stations for shaping and sealing the top flaps have been moved to a separate head carousel. Compared to the possibility of providing a larger carousel with more processing stations, this solution has the advantage of better use of space. In terms of design, the solution is particularly simple because the same components can be used to a substantial extent for the head-shaped carousel as for the filling carousel.

Die in Fig. 1 gezeigte Maschine zum Herstellen, Füllen und Verschließen von Packungen trägt eine in einem Maschinengestell 1 gelagerte Vorratsrolle 2,. von der eine flexible Materialbahn 3 abgezogen wird, die beispielsweise aus kunststoffbeschichtetem Papier besteht. In einer zunächst durchlaufenen Rillstation 4 wird die Materialbahn 3 mit einer Längsrillung versehen und anschließend zusammengelegt. In dieser Form durchläuft die Materialbahn 3 eine Druckvorrichtung 5, in der die bereits vorher bedruckte Materialbahn mit einem Datumsaufdruck versehen wird.The machine shown in FIG. 1 for producing, filling and closing packs carries a supply roll 2, which is mounted in a machine frame 1. from which a flexible material web 3 is pulled off, which consists for example of plastic-coated paper. In an initially run creasing station 4, the material web 3 is provided with a longitudinal creasing and then folded together. In this form, the material web 3 passes through a printing device 5, in which the previously printed material web is provided with a date imprint.

Anschließend durchläuft die Materialbahn 3 eine Prägestation 6, eine Längsnahtschweißstation 7 , eine Nachdrück- und Vorschubstation 8, in der die Längsnaht nachgedrückt wird und die dabei auch den Bahnvorschub bewirkt. In einer Schneidstation 10 werden die Zuschnitte für jeweils eine Packungshülle abgeschnitten und in einer Aufschiebestation 11 auf einen der Spreizdorne 12 eines in der Figur nur angedeuteten Spreizdornkarussells 13 aufgeschoben.Subsequently, the material web 3 passes through an embossing station 6, a longitudinal seam welding station 7, a pressing and feed station 8, in which the longitudinal seam is pressed and which also causes the web advance. In a cutting station 10, the blanks are cut off for each packaging sleeve and in a slide-on station 11 are pushed onto one of the expanding mandrels 12 of an expanding mandrel carousel 13, which is only indicated in the figure.

Im Uhrzeigersinn gelangt die Packung zu einer Faltstation 14, an der die beiden Seitennähte geformt werden. Die beim Zusammenlegen der Materialbahn gebildete Falte liegt am Boden der Packung. In der Station 14 werden die beim Aufschieben der Packung auf den Spreizdorn 12 entstandenen Bodenlaschen 16 der Packung 15 beheizt, um anschließend in der Bodenlaschensicgelstation 17 (Fig. 2 und 3) angesiegelt zu werden.In a clockwise direction, the pack arrives at a folding station 14, at which the two side seams are formed. The fold formed when the material web is folded lies on the bottom of the package. In the station 14, the base flaps 16 of the package 15 formed when the package is pushed onto the expanding mandrel 12 are heated in order to be subsequently sealed in the base flap sealing station 17 (FIGS. 2 and 3).

Claims (10)

Packungshülle 15, nachfolgend vereinfacht "Packung" genannt, wird in einer Übergabestation 18 vom Spreizdornkarussell 13 auf ein Füllkarussell 19 übergeben und dabei vom Spreizdorn abgestreift. In einer Füllstation 20 wird die Packung 15 gefüllt; in einer Kopfnahtspreizstation 21 wird die Kopfnaht der Packung 15 mittels Spreizfingern auseinandergezogen und in einer nachfolgenden Kopfnaht- formstation 22 so vorgeformt, daß die durchgehende Kopfnaht in einer Kopfnahtschweißstation 23 (Fig.4) geschweißt werden kann. Die verschlossene Packung 15 wird anschließend in einer Übergabestation 24 an ein Kopfformkarussell 25 übergeben und gelangt dort in eine Kopflaschenformstation 26 (Fig. 5 und 6), in der die zunächst noch abstehenden Kopflaschen 27 der Packung 15 nach unten geklappt und dabei vorgeformt werden. In einer nachfolgenden Kopflaschenheizstation 28 (Fig.7) wird die Unterseite der Kopflaschen 27 und die Packungsaußenseite beheizt, so daß in einer nachfolgenden Kopflaschensiegelstation 29 (Fig. 8 und 9) die Kopflaschen 27 an der Packungsaußenseite festgesiegelt werden können.Packing envelope 15, hereinafter simply referred to as "packing", is transferred in a transfer station 18 from expanding mandrel carousel 13 to a filling carousel 19 and is stripped from the expanding mandrel in the process. The pack 15 is filled in a filling station 20; in a head seam spreading station 21 the head seam of the pack 15 is pulled apart by means of spreading fingers and preformed in a subsequent head seam forming station 22 such that the continuous head seam can be welded in a head seam welding station 23 (FIG. 4). The sealed package 15 is then transferred to a head shaping carousel 25 in a transfer station 24 and arrives there in a head flap shaping station 26 (FIGS. 5 and 6) in which the top flaps 27 of the package 15 that are still protruding are folded down and thereby preformed. In a subsequent head flap heating station 28 (FIG. 7), the underside of the head flaps 27 and the outside of the pack are heated, so that in a subsequent head flap sealing station 29 (FIGS. 8 and 9) the head flaps 27 can be sealed on the outside of the pack. In einer Ausstoßstation 3o gelangen die fertiggestellten Packungen 15 auf einen Abgabeteller 31, von dem sie zum weiteren Verpacken abgenommen werden.In an ejection station 3o, the finished packages 15 arrive at a delivery plate 31, from which they are removed for further packaging. Die Bodenlaschenformstation 17 (Fig.2) weist zwei querbewegliche Stempelplatten 4o auf, die jeweils mit Führungsrollen 41 verbunden sind. Ein Druckmittelzylinder 42 trägt an seiner Kolbenstange 43 einen senkrecht bewegbaren Steuerkörper 44, an dem seitliche Arme 45 angebracht sind, die jeweils in einer schrägen Steuerfläche 46 enden, die mit den Führungsrollen 41 in Eingriff steht.The bottom plate forming station 17 (FIG. 2) has two transversely movable stamp plates 40, which are each connected to guide rollers 41. A pressure medium cylinder 42 carries on its piston rod 43 a vertically movable control body 44, on which lateral arms 45 are attached, each of which ends in an oblique control surface 46, which is in engagement with the guide rollers 41. Jeweils am unteren Ende der Stempelplatten 4o ist in einem Gelenk 47 eine Laschenformklappe 48 schwenkbar angebracht. Beide Laschenformlclappen 48 tragen jeweils eine Führungsrolle 49, die mit gekrümmten Steuerflächen des Steuerkörpers 44 in Eingriff stehen.At the lower end of the stamp plates 4o, a tab flap 48 is pivotally mounted in a joint 47. Both tab-shaped flaps 48 each carry a guide roller 49, which are in engagement with curved control surfaces of the control body 44. Wenn der Steuerkörper 44 durch den Druckmittelzylinder 42 nach oben bewegt wird, fahren die Stempelplatten 4o seitlich gegen die Packung 15; zugleich werden die Laschenformklappen 48 bis in die in Fig. 3 gezeigte Endstellung geschwenkt.When the control body 44 is moved upward by the pressure medium cylinder 42, the stamp plates 4o move laterally against the packing 15; at the same time the tab flaps 48 are pivoted into the end position shown in FIG. 3. In Fig. 2 ist mit strichpunktierten Linien eine in der Faltstation 14 angeordnete Bodenlaschenheizeinrichtung 51 angedeutet, durch die die Bodenlaschen 16 und die Bodenaußenfläche der Packung 15 beheizt wurden. Wenn diese beheizten Flächen dann in der Bodenlaschenformstation 17 aufeinandergedrückt werden, wie in Fig. 3 dargestellt, werden die Bodenlaschen 16 in dieser Stellung angesiegelt. Die an den Seitenflächen der Packung anliegenden Stempelplatten 40 verhindern ein Auswölben der Seitenflächen der Packung 15, wenn der für die Siegelung erforderliche Druck am Packungsboden aufgebracht wird.In FIG. 2, dash-dotted lines indicate a bottom flap heating device 51 arranged in the folding station 14, by means of which the bottom flaps 16 and the bottom outer surface of the pack 15 were heated. When these heated surfaces are then pressed together in the base plate forming station 17, as shown in FIG. 3, the base plates 16 are sealed in this position. The stamp plates 40 abutting the side surfaces of the package prevent the side surfaces of the package 15 from bulging out when the pressure required for the sealing is applied to the package base. In der Kopfnahtschweißstation 23 (Fig. 4) ist ein mittels eines Druckmittelzylinders 6o senkrecht verfahrbarer Schweißkopf 61 vorgesehen, der eine feststehende Schweißbacke 62 und eine daran angelenkte, schwenkbare Schweißbaclce 63 aufweist. Beide Schweißbacken 62, 63 sind beheizbar. An der schwenkbaren Schweißbacke 63 greift ein Druckmittelzylinder 64 an.Provided in the head seam welding station 23 (FIG. 4) is a welding head 61 which can be moved vertically by means of a pressure medium cylinder 60 and which has a fixed welding jaw 62 and a pivotable welding jaw 63 articulated thereon. Both welding jaws 62, 63 can be heated. A pressure medium cylinder 64 engages on the pivotable welding jaw 63. Wenn die Packung 15, deren Kopfnaht 65 in der Station 22 bereits vorgeformt wurde, in die Kopfnahtschweißstation 23 gelangt, befindet sich der Schweißkopf 61 zunächst in der in Fig. 4 mit strichpunktierten Linien dargestellten oberen, aufgeklappten Stellung. Der Druckmittelzylinder 6o fährt den Schweißkopf 61 nach unten; anschließend schließt der Druckmittelzylinder 64 den Schweißkopf und übt auf die Kopfnaht'65 den erforderlichen Schweißdruck unter Wärmeeinwirkung aus. Die Länge der Schweißbacken 62, 63 ist so bemessen, daß sie über die gesamte Länge der Kopfnaht 65 reicht, so daß die Kopfnaht in einem einzigen Schweißvorgang vollständig geschlossen wird. Die Kopfnaht reicht daher bis in die Kopflaschen 27.When the pack 15, the head seam 65 of which has already been preformed in the station 22, reaches the head seam welding station 23, the welding head 61 is initially in the upper, opened position shown in FIG. 4 with dash-dotted lines. The pressure medium cylinder 6o moves the welding head 61 downwards; then the pressure medium cylinder 64 closes the welding head and exerts the required welding pressure on the head seam 65 under the action of heat. The length of the welding jaws 62, 63 is dimensioned such that it extends over the entire length of the head seam 65, so that the head seam is completely closed in a single welding operation. The head seam therefore extends into the head flaps 27. Die nicht im einzelnen dargestellte Übergabestation 24 ist ähnlich aufgebaut wie die Kopfnahtschweißstation 23, wobei jedoch die Backen 62 und 63 nicht beheizt, sondern gekühlt werden. Die Kopfnaht 65 wird hier nachgedrückt und verfestigt. Die in ihrem grundsätzlichen Aufbau in Fig. 4 gezeigte Einrichtung, die in der Übergabestation 24 die Packung 15 an der Kopfnaht 65 hält, ist querverschiebbar angeordnet und transportiert die Packung 15 vom Füllkarussell 19 auf das Kopfformkarussell 25.The transfer station 24, not shown in detail, is constructed similarly to the head seam welding station 23, but the jaws 62 and 63 are not heated but cooled. The head seam 65 is pressed here and consolidated. The device shown in its basic structure in FIG. 4, which holds the package 15 at the head seam 65 in the transfer station 24, is arranged such that it can be moved transversely and transports the package 15 from the filling carousel 19 to the head-shaped carousel 25. Die Kopfformstation 26 (Fig. 5 und 6) weist einen mittels eines Druckmittelzylinders 7o senkrecht bewegbaren Formkörper 71 auf, dessen plattenförmiges Mittelstück an seinen Enden nach unten abgewinkelte Kopflaschenformbacken 72 trägt. Wenn der Formkörper 71 auf die Packung 15 abgesenkt wird ( Fig.6) drücken die Kopflaschenformbacken 72 die Kopflaschen 27 nach unten, so daß diese vorgeformt sind.The head shaping station 26 (FIGS. 5 and 6) has a shaped body 71 which can be moved vertically by means of a pressure medium cylinder 7o, the plate-shaped middle piece of which, at its ends, bears shaped top flap jaws 72. When the molded body 71 is lowered onto the pack 15 (FIG. 6), the top flap mold jaws 72 press the top flaps 27 downward so that they are preformed.
