Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a tray sealing machine comprising a feed device with the features of claim 1. Advantageous developments of the invention are specified in the subclaims.
Die erfindungsgemäße Schalenverschließmaschine umfasst eine Vorschubeinrichtung () mit wenigstens zwei zueinander parallel ausgerichtete Transportbändern zum Transportieren von Schalen und zeichnet sich dadurch aus, dass die Transportbänder mehrere Laschen umfassen, an denen Vorschubstege verdrehgesichert befestigbar sind. Die Verdrehsicherung der Vorschubstege ermöglicht den Einsatz von profilierten Vorschubstegen und somit eine Möglichkeit zur Anpassung an besonders flache aber auch hohe Schalen. Bevorzugt sind die Transportbänder Förderketten, um eine hohe Stabilität mit geringen Toleranzen in Transportrichtung bereitzustellen und in Verbindung mit Führungsleisten eine hohe Querstabilität zu ermöglichen.The tray sealing machine according to the invention comprises a feed device (10) with at least two mutually parallel conveyor belts for transporting trays and is characterized in that the conveyor belts comprise a plurality of tabs on which feed webs are secured against rotation fastened. The anti-rotation of the feed webs allows the use of profiled feed webs and thus a way to adapt to particularly shallow but also high shells. Preferably, the conveyor belts conveyor chains to provide high stability with low tolerances in the transport direction and to enable in conjunction with guide rails high lateral stability.
Dabei ist vorzugsweise die Lasche ein Teil eines Kettenglieds der Förderkette, welches eine Austauschbarkeit eines Kettenglieds zu den bisher bekannten Vorschubeinrichtungen und eine platzsparende Konstruktion ermöglicht.In this case, the tab is preferably a part of a chain link of the conveyor chain, which allows interchangeability of a chain link to the previously known feed devices and a space-saving design.
Bevorzugt ist hierbei die Lasche als Guss- oder Drehfrästeil ausgeführt, welches in einem Arbeitsgang auf einer entsprechenden Maschine hergestellt werden kann und ein vorhandenes Kettenglied der Förderkette ersetzt.Preferably, in this case, the tab is designed as a cast or turned milled part, which can be produced in one operation on a corresponding machine and replaces an existing chain link of the conveyor chain.
In einer vorteilhaften Ausführung ist das Material der Lasche Edelstahl, um gute Reinigbarkeit zu gewährleisten und hohen Hygienestandards zu genügen.In an advantageous embodiment, the material of the tab is stainless steel to ensure good cleanability and to meet high standards of hygiene.
Die Vorschubstege weisen in einer vorteilhaften Ausführungsform wenigstens eine ebene Anlagefläche auf. Dabei sind die Vorschubstege besonders zweckmäßig als Vierkantstangen vorgesehen, da sie nur an den Enden bearbeitet werden müssen, um in der Schalenverschließmaschine einsetzbar zu sein.In an advantageous embodiment, the feed webs have at least one planar contact surface. The feed webs are particularly expediently provided as square bars, since they must be processed only at the ends to be used in the tray sealing machine.
Bevorzugt ist das Material der Vorschubstege Edelstahl, um gute Reinigbarkeit zu gewährleisten und hohen Hygienestandards zu genügen.Preferably, the material of the feed webs is stainless steel, to ensure good cleanability and to meet high standards of hygiene.

Gleiche Komponenten sind in den Figuren durchgängig mit gleichen Bezugszeichen versehen.The same components are provided throughout the figures with the same reference numerals.
Im Folgenden wird der Ablauf des Betriebs der Schalenverschließmaschine 1 beschrieben.
Wird eine Reihe R von Schalen in die erste Siegelstation 2 mittels der Querstäbe 12 geschoben, so machen die Vorschubketten 13 mit den Vorschubstegen 12 am Ende eine reversible Bewegung entgegen der Produktionsrichtung P, damit sich keiner der Vorschubstege 12 mehr in der Siegelstationen 2 befindet. Denn im Anschluss an die Vorschubbewegung schließt sich die Siegelstation 2, indem ein Oberwerkzeug zusammen mit einem Unterwerkzeug derart zusammenwirken, dass sie eine Kammer um die Schale 11 bilden. Die Deckelfolie wird auf die Schalen 11 gesiegelt. Die Deckelfolie wird vor dem Öffnen der Siegelstation 2 geschnitten, damit die Schalen 11 weiter einzeln in Reihen R weitertransportiert werden können.If a row R of shells in the
Nach der Siegelstation 2 können die Schalen 11 als fertige Verpackungen auf eine nicht dargestellte Abführeinrichtung übergeben werden, um sie von dort dem nachfolgenden Produktionsprozess wie Wiegen, Etikettieren und Überprüfen zuzuführen.After the
Es ist eine Vorschubeinrichtung 5 denkbar, bei der die Förderketten 13, 13a so viele Kettenlaschen 22, 22a aufweisen, um unterschiedliche Abstände in Produktionsrichtung zwischen zwei benachbarten Vorschubstege 12 erzeugen zu können, um unterschiedliche Schalenabmessungen in der Schalenverschließmaschine 1 verarbeiten zu können.A
Alternativ zu dem dargestellten Ausführungsbeispiel kann es sich bei den Transportbändern auch um Riemen handeln, insbesondere um Zahnriemen. Eine weitere Variationsmöglichkeit besteht darin, dass die zur Verdrehsicherung ausgebildete Kettenlasche 22 nur eine ebene Fläche 24, nicht aber die zusätzliche Ausnehmung 25 aufweist, oder aber dass die Kettenlasche 22 zwei gegebenenfalls zueinander parallele ebene Flächen 24 auf gegenüberliegenden Seiten aufweist.As an alternative to the exemplary embodiment illustrated, the conveyor belts may also be belts, in particular toothed belts. Another possible variation is that the
