Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Bildung einer Längsnaht eines Folienschlauches mit einer Formschulter zum Umlegen einer flexiblen Folie um ein Formatrohr einer Transporteinrichtung für den Weitertransport der Folie und des geformten Folienschlauches, einer Einrichtung zur Verschweißung der Längsnaht, wobei die Einrichtung zur Verschweißung der Längsnaht ein um zwei Rollen umlaufendes Siegelband aufweist, das Siegelband mittels einer Heizeinrichtung erhitzbar ist, und eine der Rollen mittels eines Antriebs angetrieben wird.The The invention relates to a device for forming a longitudinal seam a film tube with a forming shoulder for folding a flexible film around a format tube of a transport device for further transport the film and the molded film tube, a device for welding the longitudinal seam, wherein the means for welding the longitudinal seam one by two rollers has circumferential sealing strip, the sealing strip by means of a heating device is heated, and one of the rollers driven by a drive becomes.
Eine
derartige Vorrichtung mit zwei die Längsnaht einklemmenden Siegelbändern ist
aus der
Die bekannten Vorrichtungen haben den Nachteil, dass sie keine unterschiedliche Art der Wärmeeinbringung von gegenüberliegenden Seiten der Längsnaht erlauben. Entweder weist eine Vorrichtung nur ein Siegelband oder nur eine Heißsiegelbacke zum Längsnahtverschweißen auf, wodurch eine Wärmeeinbringung von gegenüberliegenden Seiten der Längsnaht möglich ist. Oder zwei baugleiche Siegelbänder erwärmen von gegenüberliegenden Seiten her eine vom Folienschlauch abstehende Längsnaht. Dann ist ihre Art der Wärmeeinbringung gleich. Eine von zwei gegenüberliegenden Seiten ausgeübte unterschiedliche Art der Wärmeeinbringung und auch der Druckeinbringung kann jedoch die Längsnaht beeinflussen.The known devices have the disadvantage that they are no different Type of heat input from opposite Sides of the longitudinal seam allow. Either a device has only a sealing band or only a heat sealing jaw for longitudinal seam welding, whereby a heat input from opposite Sides of the longitudinal seam possible is. Or two identical sealing strips heat from opposite Side her a protruding from the film tube longitudinal seam. Then its kind the heat input equal. One of two opposite Pages exercised different type of heat input and also the pressure input can influence the longitudinal seam.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Vorrichtung der eingangs beschriebenen Art von gegenüberliegenden Seiten einer Längsnaht eine unterschiedliche Wärmeeinbringung zu erreichen.Of the Invention is based on the object in a device of initially described type of opposite sides of a longitudinal seam a different heat input to reach.
Gelöst ist die Aufgabe gemäß dem kennzeichnenden Teil des Anspruchs 1. Danach weist die Einrichtung eine Heißsiegelbacke auf, und die Längsnaht ist zwischen dem Siegelband und der Heißsiegelbacke eingeklemmt, um von der einen Seite von der Heißsiegelbacke und von der anderen Seite von dem Siegelband mit Wärme versorgt werden zu können.Solved is the Task according to the characterizing Part of claim 1. Thereafter, the device has a heat sealing jaw on, and the longitudinal seam is trapped between the sealing band and the heat seal jaw to from one side of the heat sealing jaw and supplied with heat from the other side of the sealing band to be able to.
Die vorgeschlagene Neuerung weist mehrere Vorteile auf. Zum einen kann von gegenüberliegenden Seiten eine Wärmeeinbringung in die Längsnaht erfolgen, und die Art der Wärmeeinbringung ist unterschiedlich. Zum anderen bildet die Heißsiegelbacke mit ihrer Siegelfläche einen geradlinigen, ebenen mechanischen Widerstand für das Siegelband. Und schließlich ist die Heißsiegelbacke sehr robust und erhöht auch die Nutzungsdauer des Siegelbandes, indem dieses auf einen ebenen Widerstand abrollt. Die Wärmeeinbringungen sind unterschiedlich, da das Siegelband mit der weiterbewegten Längsnaht umläuft und es somit keinen Schlupf zwischen dem Siegelband und der Längsnaht gibt, wodurch eine sehr gute Wärmeeinleitung in die Längsnaht erfolgt. Dagegen gleitet die Längsnaht über die ortsfeste Heißsiegelbacke. Die Strahlungswärme der Heißsiegelbacke bleibt dabei vergleichsweise hoch. Im Vergleich zu einer reinen Wärmeeinbringung mittels ortsfester Heißsiegelbacke und im Vergleich zu einem einzigen Siegelband oder zu zwei Siegelbändern ist ein Schweißergebnis erreicht, welches die Vorteile einer Heißsiegelbacke mit den Vorteilen eines Siegelbandes kombiniert, und wobei die Längsränder der Folienbahn gut geführt werden.The proposed innovation has several advantages. For one thing from opposite Sides a heat input in the longitudinal seam done, and the type of heat input is different. On the other hand forms the heat seal jaw with its sealing surface a rectilinear, level mechanical resistance for the sealing band. And finally is the heat sealing jaw very robust and elevated Also, the useful life of the seal band by this on a even resistance rolls. The heat inputs are different, since the sealing band with the moving longitudinal seam circulated and thus there is no slip between the sealing band and the longitudinal seam gives, giving a very good heat input in the longitudinal seam he follows. In contrast, the longitudinal seam slides over the stationary heat sealing jaw. The radiant heat the heat sealing jaw remains relatively high. Compared to a pure one heat input by means of stationary heat sealing jaw and compared to a single seal band or to two seal bands a welding result Achieved the benefits of a heat seal jaw with the advantages a sealing tape combined, and wherein the longitudinal edges of the film web are well managed.
Weitere, vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind in den Ansprüchen 2 bis 4 beschrieben.Further, advantageous embodiments of the device according to the invention are in the claims 2 to 4 described.
Ist die Vorrichtung Teil einer vertikalen Schlauchbeutelmaschine, an deren Formatrohr die Einrichtung zur Verschweißung der Längsnaht vorgesehen ist (Anspruch 2), so erfolgt die Längsnahtverschweißung eines Folienschlauches in zuverlässiger Weise an einer dafür geeigneten Verpackungsmaschine.is the device is part of a vertical flow wrapper, on whose format tube the device is provided for welding the longitudinal seam (claim 2), the longitudinal seam welding takes place Foil tube in a reliable way at one for it suitable packaging machine.
Durch wahlweises Ein- bzw. Ausschalten der Heizung der Heißsiegelbacke (Anspruch 3) bzw. der Heizung des Siegelbandes (Anspruch 4) kann die Vorrichtung, je nach zu verschweißendem Folientyp bzw. Foliendicke, auf vier unterschiedliche Arten betrieben werden.By optional switching on or off the heating of the heat sealing jaw (Claim 3) or the heating of the sealing strip (claim 4) can the device, depending on the type of film or film thickness to be welded, be operated in four different ways.
So kann das Siegelband beheizt werden und gegen eine kalte Heißsiegelbacke wirken, sowohl das Siegelband als auch die Heißsiegelbacke werden beheizt, nur die Heißsiegelbacke ist beheizt und wirkt gegen das umlaufende, kalte Siegelband und schließlich, beide Siegelaggregate sind kalt und dienen nur zum Zusammendrücken der Folienbahnränder (Kaltpressverfahren).So The sealing band can be heated and against a cold heat sealing jaw Both the sealing band and the heat-sealing jaw are heated, only the heat sealing jaw is heated and acts against the circulating, cold seal band and finally, both Sealing units are cold and serve only to squeeze the Sheet edges (Cold-pressing).
