Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Folieneinschweißung flächiger Produkte gemäße den Oberbegriffen der Ansprüche 1 und 6.The invention relates to a device and a method for Folieneinschweißung sheet products according to the preambles of
Solche flache bzw. flächige Produkte können beispielsweise aus einzuschweißenden Kalendern bestehen, wobei die bekannten Vorrichtungen in Längsrichtung der Produkte unschöne breite Folienränder erzeugen, die zum Teil durch Umlegen auf die Rückseite der Produkte per Hand nachgearbeitet werden müssen.Such flat or sheet-like products can consist, for example, of calendars to be welded in, the known devices producing unsightly wide film edges in the longitudinal direction of the products, which in part must be reworked by folding over to the back of the products by hand.
Ein solcher aus der
Eine andere bekannte Vorrichtung zum Umhüllen von Druckereiprodukten mit einem Verpackungsmaterial,
Bekannt ist auch eine Vorrichtung zum Verpacken von flachem, biegsamen Verpackungsgut in einem Verpackungsbeutel aus einer ebenfalls übereinander gelegten Folienbahn, in der das flache Verpackungsgut während des Verschießens der Folie an der einer Naht entgegengesetzten Falzseite der Folie angehoben und gebogen wird, damit das Verpackungsgut anschließend in einer flach liegenden Position den Innenraum der Folienverpackung vollständig ausfüllt (
Diese bekannten Vorrichtungen und die damit durchführbaren Verpackungsverfahren erzeugen so entweder eine unschöne Verpackung oder das Erfordernis eine manuellen Nacharbeitung der Verpackung oder aber das zeitweilige Verformen der einzupackenden Gegenstände, was zum einen einen negativen optischen Produkteindruck mit sich bringt oder aber einen erhöhten technischen oder wirtschaftlichen Aufwand bedeutet.These known devices and the packaging methods that can be carried out thus produce either unsightly packaging or the requirement for manual reworking of the packaging or the temporary deformation of the items to be packaged, which on the one hand brings about a negative visual product impression or means an increased technical or economic expense ,
Aufgabe der Erfindung ist es, eine Vorrichtung und ein Verfahren zur Folieneinschweißung solcher flacher bzw. flächiger Produkte zur Verfügung zu stellen, die ohne erforderliche Nacharbeit sofort ein optimales Verpackungsergebnis liefern.The object of the invention is to provide a device and a method for Folieneinschweißung such flat or flat products available that provide immediately without reworking an optimal packaging result.
Die Lösung dieser Aufgabe ergibt sich in Verbindung mit den Oberbegriffsmerkmalen erfindungsgemäß im Zusammenhang mit den kennzeichnenden Merkmalen der Ansprüche 1 und 6.The solution to this problem arises in conjunction with the preamble features according to the invention in conjunction with the characterizing features of
Dadurch, dass die Längsschweißeinheiten in einer Transportrichtung der Förderbänder erfindungsgemäß voneinander entfernt angeordnet sind, ergibt sich die Möglichkeit, vor der zweiten Längsschweißeinheit Schrägzugwalzen zur Transportrichtung leicht schräg angestellt auf den später abzutrennenden Folienrand abrollen zu lassen, mit denen die Oberfolie und die Unterfolie unter einem einzuschweißendem Produkt so durchziehbar ist, dass die erste Längsschweißnaht der gegenüberliegenden Seite an das Produkt herangezogen werden kann, welches selber in Richtung der zweiten Längsschweißeinheit bewegt wird, aber dort von einem seitlichen Produktanschlag abgestützt wird, unter dem die Ober- und Unterfolie in Längs- und/oder Querrichtung hindurch bewegbar ist.Characterized in that the longitudinal welding units are arranged according to the invention away from each other in a transport direction of the conveyor belts, it is possible to roll obliquely before the second longitudinal welding unit Schrägzugwalzen the transport direction obliquely to the later separated film edge roll, with which the upper film and the lower film unterweißendemendem Product is so durchziehbar that the first longitudinal weld on the opposite side of the product can be used, which is itself moved in the direction of the second longitudinal welding unit, but there is supported by a lateral product stop, under which the top and bottom film in longitudinal and / or or transverse direction is movable therethrough.
Dies ermöglicht es, die zweite Längsschweißeinheit unmittelbar benachbart des Produktes zu erzeugen, so dass nur ein minimaler Folienüberstand von wenigen mm, jedenfalls unterhalb 1 cm erzeugt werden kann. Der optische Eindruck eines so verpackten Produktes ist sofort nach der Verpackung optimal und es ist auch nicht erforderlich, das erzielte Ergebnis durch manuelle Bearbeitung nacharbeiten zu müssen, so dass diese erfinderische Vorrichtung einen Sprung in der Wirtschaftlichkeit der Warenverpackung gewährleistet.This makes it possible to produce the second longitudinal welding unit immediately adjacent to the product, so that only a minimum film projection of a few mm, at least below 1 cm can be produced. The visual impression of such a packaged product is optimal immediately after packaging and it is not necessary to rework the result achieved by manual processing, so that this inventive device ensures a jump in the economics of the product packaging.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den rückbezogenen Ansprüchen.Further advantageous embodiments of the invention will become apparent from the dependent claims.
Gemäß einer bevorzugten Ausführungsform der Erfindung sind mehrere Schrägzugwalzen in Transportrichtung hintereinander angeordnet, so dass sich die Spannung in den Folien schrittweise vergrößern lässt, was die Betriebssicherheit der Vorrichtung und das Prozessergebnis weiter verbessert.According to a preferred embodiment of the invention, a plurality of diagonal tension rollers are arranged one behind the other in the transport direction, so that the tension in the films can be increased stepwise, which further improves the operational reliability of the device and the process result.
Eine weitere Steigerung erfolgt dadurch, dass die einzelnen Schrägzugwalzen in Transportrichtung mit einem sich vergrößernden Schräglaufwinkel versehen sind, wodurch sich die erhöhte Schräglaufspannung weiter vergrößert.A further increase takes place in that the individual oblique tension rollers are provided in the transport direction with an increasing skew angle, whereby the increased skew tension further increases.
Zur Verwirklichung dieser Vorrichtung sind die Schräglaufwalzen an schwenkbar gelagerten Hebelarmen angeordnet, die auf ihren den Walzen gegenüberliegenden Enden mit Spindelmuttern versehen sind, die über an der Vorrichtung gelagerte Spindeln und einen Stellantrieb verschwenkbar sind, so dass auch die Ausführung der erfinderischen Vorrichtung höchst einfach aber sehr präzise erfolgt. Die Schrägzugwalzen sind dabei von innen nach außen seitlich hinter dem oberen und unteren Produktanschlag sowie einer oberen und unteren Transportriemenführung mit den oberen und unteren Transportriemen angeordnet, wodurch sich eine optimale Zugänglichkeit der Schrägzugwalzen ergibt.To realize this device, the skew rollers are arranged on pivotally mounted lever arms, which are provided on their opposite ends of the rollers with spindle nuts which are pivotable about mounted on the device spindles and an actuator, so that the execution of the inventive device very simple but very precise. The Schrägzugwalzen are arranged from the inside to the outside laterally behind the upper and lower product stop and an upper and lower conveyor belt guide with the upper and lower conveyor belt, resulting in optimum accessibility of the Schrägzugwalzen.
Nachfolgend wird der Ablauf des Verfahrens anhand von Figuren näher beschrieben. Es zeigen:The course of the method will be described in more detail below with reference to figures. Show it:
