Abstract

The chamber machine and especially a conveyor chamber machine, to seal filled film bags, has a sealing rail (140) of flexible plastics which can be shaped. The rail has a number of segments, which can be moved in relation to each other to give the required shape. The rail incorporates a sealing wire (15) with cable connections (19).

Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Siegeln von Packungen, insbesondere für eine Kammermaschine bzw. eine Kammerbandmaschine.The The present invention relates to a device for sealing of packs, especially for a chamber machine or a chamber belt machine.

Bei bekannten Kammermaschinen, die beispielsweise Produkte in Beutel verpacken, sind gerade, starre Siegelschienen bekannt, die den Beutel beim Verpacken des Produkts versiegeln. Die so erzeugte Siegelnaht verläuft geradlinig. Je nach Größe und Form des verpackten Produkts ist eine solche Siegelnaht unvorteilhaft und insbesondere bei Beuteln, die nicht geschrumpft werden optisch nicht sehr ansprechend, da große Teile des Beutels nicht von dem verpackten Produkt ausgefüllt werden und der Beutel einen großen Beutelhals aufweist. Die Gestaltung der Packung ist daher beschränkt.at known chamber machines, for example, products in bags Straight, rigid sealing rails are known which pack the bag when packing Seal the packaging of the product. The sealed seam thus produced runs straight. Depending on size and shape of the packaged product, such a sealed seam is unfavorable and especially for bags that are not shrunk optically not very appealing, because big Parts of the bag should not be filled by the packaged product and the bag a big one Bag neck has. The design of the package is therefore limited.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine verbesserte Vorrichtung zum Siegeln von Packungen bereitzustellen, die es ermöglicht, das zu verpackende Produkt optisch ansprechender zu versiegeln.The Object of the present invention is therefore to provide an improved To provide a device for sealing packages that allows the to seal product to be packaged visually appealing.

Die Aufgabe wird gelöst durch eine Vorrichtung gemäß Anspruch 1. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.The Task is solved by a device according to claim 1. Further developments of the invention are specified in the subclaims.

Durch die erfindungsgemäße Ausgestaltung der Siegelschiene insbesondere das Verwenden eines deformierbaren Kunststoffs, ist ein flexibles Anpassen an die jeweilige Verpackungskontur bzw. Beutelkontur möglich, was sowohl die Optik der erzeugten Packung verbessert. Darüber hinaus müssen die Beutel nicht geschrumpft werden, da die Siegelnaht bereits an das Produkt angepasst ist. Ein weiterer Aspekt der Erfindung ist es, die Siegelschiene modulartig aus mehreren Siegelschienensegmenten aufzubauen. Durch diesen Aufbau ist ebenfalls ein flexibles Anpassen an die Packungskontur möglich. Die verschiedenen Segmente werden vorteilhafterweise durch einen Siegeldraht miteinander verbunden. Eine weitere Möglichkeit ist es, diese Verbindung der Segmente mit einem Metallgeflecht zu realisieren, das gleichzeitig auch eine gleichmäßige Kraftverteilung bei der Siegelung bewirkt.By the embodiment of the invention Sealing rail, in particular the use of a deformable plastic, is a flexible adaptation to the respective packaging contour or bag contour possible, which improves both the appearance of the pack produced. Furthermore have to the bags are not shrunk because the sealed seam is already on the product is adapted. Another aspect of the invention is it, the sealing rail modular from several sealing rail segments build. By this structure is also a flexible customization to the packaging contour possible. The various segments are advantageously by a Siegel wire connected together. One more way It is this connection of segments with a metal braid too realize, at the same time a uniform force distribution in the Seal causes.
