Die erfindungsgemäße Tiefziehverpackungsmaschine weist wenigstens zwei Klammerketten zum beidseitigen Halten einer Unterfolie und zum Transportieren der Unterfolie entlang einer Produktionsrichtung der Tiefziehverpackungsmaschine auf, wobei die Klammerketten in Kettenführungen geführt sind. Die Kettenführungen weisen jeweils eine obere Führungsfläche und eine untere Führungsfläche auf, zwischen denen jeweils eine Klammerkette führbar ist. Die Tiefziehverpackungsmaschine weist eine Formstation zum Erzeugen von Mulden in eine Unterfolie, eine Siegelstation und wenigstens eine Schneidstation auf, die in dieser Reihenfolge entlang der Produktionsrichtung an einem Maschinengestell angeordnet sind, wobei sich die Kettenführungen wenigstens von der Formstation entlang einer Einlegestrecke zur Siegelstation erstrecken, und wobei die obere Führungsfläche an bzw. entlang der Formstation eine horizontale Ausrichtung aufweist und einen ersten vertikalen Abstand von einer Aufstellfläche des Maschinengestells der Tiefziehverpackungsmaschine hat, wobei die Kettenführungen an bzw. entlang der Siegelstation eine horizontale Ausrichtung aufweisen und die obere Führungsfläche einen zweiten vertikalen Abstand von der Aufstellfläche hat, wobei der zweite Abstand größer ist als der erste Abstand, sowie die Kettenführung entlang der Einlegestrecke wenigstens teilweise eine ansteigende Ausrichtung aufweist. Die erfindungsgemäße Tiefziehverpackungsmaschine zeichnet sich dadurch aus, dass das Produkteinlegeband wenigstens zwei separat antreibbare Bänder aufweist. Die Tiefziehverpackungsmaschine weist je ein Band pro Spur auf, wobei eine Spur durch in Produktionsrichtung aufeinanderfolgende Mulden definiert ist. Diese Ausführung einer Tiefziehverpackungsmaschine erlaubt eine kurze Einlegestrecke, da ein Produktzuführband Produkte auf einfache und prozesssichere Weise zumindest im Wesentlichen horizontal zuführen und in Mulden einlegen kann. Die separat antreibbaren Bänder ermöglichen eine Korrektur von unterschiedlich ankommenden Produkten zwischen den einzelnen Spuren, so dass die Einlegegenauigkeit der Produkte in die Mulden stark verbessert wird.The thermoforming packaging machine according to the invention has at least two staple chains for holding a lower film on both sides and for transporting the lower film along a production direction of the thermoforming packaging machine, wherein the staple chains are guided in chain guides. The chain guides each have an upper guide surface and a lower guide surface, between each of which a staple chain can be guided. The thermoforming packaging machine has a forming station for forming depressions in a lower film, a sealing station and at least one cutting station, which in this Sequence along the production direction are arranged on a machine frame, wherein the chain guides extend at least from the forming station along an insertion path to the sealing station, and wherein the upper guide surface on or along the forming station has a horizontal orientation and a first vertical distance from a footprint of the machine frame the thermoforming packaging machine, wherein the chain guides at or along the sealing station have a horizontal orientation and the upper guide surface has a second vertical distance from the footprint, wherein the second distance is greater than the first distance, as well as the chain guide along the insertion path at least partially has increasing orientation. The thermoforming packaging machine according to the invention is characterized in that the product inlay belt has at least two separately drivable belts. The thermoforming packaging machine has one band per track, wherein one track is defined by successive troughs in the direction of production. This embodiment of a thermoforming packaging machine allows a short insertion path, since a product feeding belt can deliver products in a simple and process-reliable manner, at least substantially horizontally, and place them in trays. The separately drivable belts allow a correction of different incoming products between the individual tracks, so that the insertion accuracy of the products in the wells is greatly improved.

So können vorhandenen Ungenauigkeiten bezüglich der Lage der Produkte in Produktionsrichtung auf dem Produktzuführband erfasst werden und bereits bei der Übernahme auf das Produkteinlegeband berücksichtigt werden.In this case, in an advantageous embodiment variant, a device with one or more sensors is provided in front of the separation point in order to detect the position of the products for each track of the product insertion band. Thus, existing inaccuracies in the position of the products in the production direction on the product feed belt can be detected and taken into account already at the time of the takeover on the product infeed belt.
Ein erfindungsgemäßes Verfahren zum Betrieb einer zuvor beschriebenen Tiefziehverpackungsmaschine zeichnet sich dadurch aus, dass die Bänder des Produkteinlegebands derart angesteuert werden, dass bei der Übergabe der Produkte vom Produktzuführband die Bänder separat mit dem Produktzuführband angesteuert werden, um Positionsunterschiede benachbarter Produkte in Produktionsrichtung zu korrigieren. Dies verbessert den nachfolgenden Einlegeprozess und führt zu einer Verbesserung der Lagegenauigkeit der Produkte in den Mulden, um manuelle Nachkorrekturen durch eine Bedienperson zu vermeiden oder wenigstens zu reduzieren.A method according to the invention for operating a thermoforming packaging machine described above is characterized in that the belts of the product insert belt are controlled such that when transferring the products from the product supply belt, the belts are controlled separately with the product supply belt to correct positional differences of adjacent products in the production direction. This improves the subsequent loading process and leads to an improvement in the positional accuracy of the products in the troughs to avoid or at least reduce manual post-corrections by an operator.
Vorzugsweise wird bei der Übergabe des Produkts auf das jeweilige Band die Geschwindigkeit dieses Bands mit der Geschwindigkeit des Produktzuführbands synchronisiert, um die Kenntnis über die Lage des Produkts mittels einer Streckensteuerung nicht zu verlieren und/oder eine Verformung des Produkts zu verhindern.Preferably, upon transfer of the product to the respective belt, the speed of this belt is synchronized with the speed of the product supply belt so as not to lose knowledge of the position of the product by means of a line control and / or to prevent deformation of the product.
Bevorzugt wird mittels eines oder mehrerer Sensoren vor der Trennstelle die Position von nebeneinander benachbarten Produkten erfasst und diese Information an eine Steuerung der Tiefziehverpackungsmaschine übermittelt, wobei die Steuerung die Information über die Positionen auswertet und den Unterschied von einer Vorderkante eines ersten Produkts der ersten Spur zu der Vorderkante eines zweiten Produkts der zweiten Spur ermittelt. Somit kann eine Egalisierung bzw. ein Ausgleichen dieses Unterschiedes bei der Übernahme und vor dem Einlegen erfolgen und ein exaktes Einlegen erfolgen.Preferably, by means of one or more sensors in front of the separation point, the position of adjacent products is detected and this information is transmitted to a control of the thermoforming packaging machine, wherein the controller evaluates the information about the positions and the difference from a leading edge of a first product of the first track to the Front edge of a second product of the second track determined. Thus, a leveling or balancing this difference in the acquisition and before inserting done and make an exact insertion.
Dabei steuert die Steuerung die Bänder bei der Übernahme der Produkte jeweils bevorzugt so an, dass nach der Übernahme die Vorderkanten von in Produktionsrichtung aufeinander folgenden Produkten jeweils einer Spur einen vorgesehenen Abstand aufweisen, der vorzugsweise einem Abstand von aufeinanderfolgenden Mulden in der Unterfolie entspricht.In this case, the control system preferably controls the bands during the takeover of the products in such a way that, after the takeover, the leading edges of successive products in the production direction each have a predetermined distance, which preferably corresponds to a spacing of successive depressions in the lower foil.
Vorzugsweise erfolgt die Übernahme der Produkte durch das Produkteinlegeband, während der Vorschub der Klammerketten stillsteht.Preferably, the takeover of the products by the product insert belt, while the feed of the staple chains is stopped.
Im Folgenden wird ein vorteilhaftes Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher dargestellt. Dabei zeigen:

Die Klammerketten 7 sind in einer Kettenführung 30, in
Der Verlauf der Kettenführung 30 von der Formstation 8 zur Siegelstation 12 ist etwa S-förmig ausgebildet. Die Kettenführung 30 ist in den Bereichen der Formstation 8 und der Siegelstation 12 horizontal ausgerichtet und im Bereich der Einlegestrecke 9 weist die Kettenführung 30 einen von der Formstation 8 zur Siegelstation 12 ansteigenden Verlauf auf. Die obere Führungsfläche O entlang der Formstation 8 weist eine horizontale Ausrichtung und einen ersten vertikalen Abstand V1 von einer Aufstellfläche A auf. Die obere Führungsfläche O entlang der Siegelstation 12 weist eine horizontale Ausrichtung und einen zweiten vertikalen Abstand V2 von einer Aufstellfläche A auf. Bei den Übergängen von der Formstation 8 zur Einlegestrecke 9 und von der Einlegestrecke 9 zur Siegelstation 12 weist die Kettenführung jeweils einen radialen Verlauf mit einem Radius RA von 500 mm bis 1000 mm auf. Dies sorgt einerseits für sanfte Übergänge der Kettenführung 30, damit keine Knicke in den Mulden 11 vor allem beim Einsatz von Hartfolien entstehen. Andererseits soll die Einlegestrecke 9 nicht unnötig lang ausgeführt sein, um die Gesamtmaschinenlänge der Tiefziehverpackungsmaschine 1 möglichst kurz zu halten.The course of the chain guide 30 from the forming
