Abstract
Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Formschulter zum Formen eines Folienschlauches, mit einem Schultermantel als Auflagefläche für eine zuzuführende Packstoffbahn und mit einer an den Schultermantel entlang einer Umformkante angrenzenden, eine Achsrichtung definierende Schulterwand als Auflagefläche für einen an der Umformkante aus der Packstoffbahn geformten Folienschlauch mit in Achsrichtung liegender Schlauchachse. Im Rahmen der Erfindung liegt auch eine Schlauchbeutelmaschine mit einer erfindungsgemässen Formschulter.The Invention relates to a forming shoulder for forming a film tube, with a shoulder coat as support surface for a supplied packaging material web and with one on the shoulder coat along a forming edge adjacent, defining an axial direction shoulder wall as bearing surface for one at the Umformkante formed from the packaging material film tube with in the axial direction lying hose axis. Within the scope of the invention is also a Tubular bag machine with a form shoulder according to the invention.
Stand der TechnikState of the art
Aus
Es besteht der Wunsch, längliche, schmale Schlauchbeutel – so genannte „StickPack"-Beutel – mit hoher Leistung in der Grössenordnung 100 Takte/Minute herzustellen. Um die Leistung weiter zu erhöhen, werden StickPack-Maschinen mehrbahnig ausgeführt, d. h., die Maschinen verarbeiten mehrere Packstoffbahnen über eine entsprechende Anzahl Formschultern, so dass mehrere Packungen parallel gefertigt werden.It there is a desire, elongated, narrow tubular bag - so called "StickPack" bags - with high performance in the order of 100 cycles / minute. Around To further increase performance, are StickPack machines multi-lane design, d. h., process the machines several packing material webs over a corresponding number of forming shoulders, so that several packs are made in parallel.
Darstellung der. ErfindungPresentation of the. invention
Der Erfindung liegt die Aufgabe zugrunde, eine Formschulter der eingangs genannten Art so auszugestalten, dass die Bauhöhe zur Erhöhung der Füllleistung ohne die sich aus einem steileren Einlaufwinkel auf das Verhalten der Folie nach der Umformkante ergebenden Nachteile weiter verringert werden kann.Of the Invention is based on the object, a forming shoulder of the beginning so-called type in such a way that the height to increase the filling capacity without resulting from a steeper inlet angle on the behavior of the film after the forming edge resulting disadvantages can be further reduced.
Zur erfindungsgemässen Lösung der Aufgabe führt, dass unterhalb der Umformkante in der Schulterwand wenigstens eine mit einer Vakuumquelle verbindbare Öffnung zum Ansaugen des Folienschlauches an die Schulterwand vorgesehen ist.to inventive solution of the task leads, that below the forming edge in the shoulder wall at least one An intake port connectable to a vacuum source the film tube is provided on the shoulder wall.
Bei einer bevorzugten Ausführung der erfindungsgemässen Formschulter ist eine Vielzahl von Öffnungen vorgesehen.at a preferred embodiment of the inventive Form shoulder is provided a variety of openings.
Durch einen über die Öffnungen aufgebrachten Unterdruck zwischen der Folie und der Formwand wird die Folie gegen die Formschulterwand gesaugt und läuft somit wellen- und knitterfrei. Durch den glatten Lauf wird das Verpackungsmaterial geschont, so dass z. B. ein Delaminieren vermieden werden kann, Ebenso werden Falten, die zu undichten Nähten und unschönen Packungen führen, vermieden. Durch die Stützwirkung des Vakuums kann im Einzelfall auf ein von innen stützendes Dosierrohr verzichtet werden.By a vacuum applied via the openings between the film and the mold wall, the film is against the Formschulterwand sucked and thus runs wave and wrinkle free. By the smooth running the packaging material is spared, so that z. B. Delamination can be avoided, as will wrinkles lead to leaky seams and unsightly packs, avoided. Due to the supporting effect of the vacuum can in individual cases be dispensed with an internally supporting dosing.
Die Öffnungen können erste Enden von die Formschulter durchsetzenden Bohrungen oder Schlitzen sein, die mit zweiten Enden bevorzugt in einen mit einem Hauptkanal verbindbaren Sammelkanal münden, wobei der Hauptkanal an eine Vakuumquelle anschliessbar ist.The openings can pass through first ends of the form shoulder Holes or slots are preferred with second ends in open a collecting channel which can be connected to a main channel, wherein the main channel is connectable to a vacuum source.
Die Öffnungen sind bevorzugt symmetrisch zu einer in Achsrichtung durch den höchsten Punkt der Umformkante verlaufenden Linie innerhalb eines durch 1/4 bis 1/3 der Umfangslinie der Schulterwand begrenzten und in Achsrichtung vom höchsten Punkt der Umformkante bis zu einem Abstand entsprechend 1/3 des Abstandes zwischen höchstem und tiefsten Punkt der Umformkante reichenden Flächenbereiches der Schulterwand angeordnet.The openings are preferably symmetrical to one in the axial direction through the highest Point of the forming edge running line within a by 1/4 limited to 1/3 of the circumferential line of the shoulder wall and in the axial direction from the highest point of the forming edge to a distance corresponding to 1/3 of the distance between highest and lowest Point of the forming edge reaching surface area of the shoulder wall arranged.
Bei Verwendung eines von innen stützenden Dosierrohres ist es normalerweise ausreichend, wenn die Öffnungen in einem verhältnismässig kleinen Bereich direkt unterhalb der Umformkante angeordnet sind. Soll jedoch auf ein Dosierrohr verzichtet werden, so sind die Öffnungen im wesentlichen über die gesamte Länge der Formschulter anzuordnen.at Use of an internally supporting metering tube is It is usually sufficient if the openings in one relatively small area directly below the Umformkante are arranged. But should be on a dosing tube are omitted, the openings are essentially on the to arrange the entire length of the forming shoulder.
Die Öffnungen weisen bevorzugt einen Durchmesser bzw. eine Schlitzbreite von etwa 0,5 bis 3 mm auf.The openings preferably have a diameter or a slot width of about 0.5 to 3 mm.
Der Zwischenraum zwischen den Öffnungen übt eine Stützfunktion auf die der Formschulter anliegenden Folie aus, während die Gesamtfläche der Öffnungen die durch das angelegte Vakuum auf die Folie wirkende Zugkraft beeinflusst. Für eine optimale Verfahrensführung ist ein geeignetes Verhältnis zwischen der der Fläche des Zwischenraumes und der Gesamtfläche der Öffnungen erforderlich.The space between the openings exerts a supporting function on the foil bearing the forming shoulder, while the total area of the Apertures affect the tensile force acting on the film by the applied vacuum. For optimum process control, a suitable ratio between the area of the gap and the total area of the openings is required.
Die als Stützfläche für die Folie dienende Fläche des Zwischenraumes zwischen den Öffnungen im Bereich der Öffnungen beträgt bevorzugt mindestens 40%, insbesondere 50 bis 70%, der aus dem Zwischenraum und den Öffnungen bestehenden Gesamtfläche dieses Bereiches.The as a support surface for the foil serving surface the space between the openings in the region of the openings is preferably at least 40%, in particular 50 to 70%, the existing of the gap and the openings Total area of this area.
Die sich mit der erfindungsgemässen Formschulter u. a. ergebenden Vorteile sind
- – Kurze Bauhöhe, damit niedrige Fallhöhe und hohe Maschinenleistung.
- – Schonung des Verpackungsmaterials, keine Beschädigung durch Delamination.
- – Erhöhte Dichtigkeit und Prozesssicherheit.
- – Erhöhte optische Qualität der Packungen.
- – Möglicher Verzicht auf ein Dosierrohr.
- – Der erforderliche Stütz- bzw. Unterdruck kann eingestellt und damit der Folienlauf über eine Beeinflussung der Reibung optimiert werden.
- - Short height, so low drop height and high machine performance.
- - Protection of the packaging material, no damage due to delamination.
- - Increased tightness and process reliability.
- - Increased optical quality of the packages.
- - Possible waiver of a dosing tube.
- - The required support or negative pressure can be adjusted and thus the film run can be optimized by influencing the friction.
