Diese Hubvorrichtung benötigt jedoch sehr viel Raum, so daß die Länge der Verpackungsmaschine unnötig vergrößert wird. Darüber hinaus ist der Hubmechanismus vergleichsweise langsam und aufwendig, weil z.B. zwei Kniehebel benötigt werden, um ein Verkanten der Platte an den Führungsstangen zu vermeiden.EP 0 569 937 B1, on the other hand, discloses a packaging machine with a Workstation having a lifting device, in which the lower tool by a Knee lever system and a piston-cylinder device raised or lowered becomes. However, this lifting device requires a lot of space, so that the length of the Packaging machine is unnecessarily increased. In addition, the Lifting mechanism comparatively slow and expensive, because e.g. two toggle levers needed to avoid tilting of the plate on the guide rods.
Es stellt sich deshalb die Aufgabe, eine Verpackungsmaschine zur Verfügung zu stellen, mittels deren Hubvorrichtung eine Platte bzw. ein Unterwerkzeug vergleichsweise schnell abgesenkt und angehoben werden kann.It is therefore the task of making a packaging machine available make, by means of which lifting a plate or a lower tool can be lowered and raised comparatively quickly.
Die Aufgabe wird erfindungsgemäß durch eine Verpackungsmaschine mit den Merkmalen des Patentanspruchs 1.The object is achieved by a packaging machine with the Features of claim 1.

The plate in turn has at least one preferably two guide bushes, who pick up the rods.
In einer bevorzugten Ausführungsform sind die Jochs vorzugsweise am unteren Ende der Stangen vorzugsweise vertikal verschieblich gelagert, wobei jeweils ein Joch von zwei Stangen gehalten wird. Diese Ausführungsform der erfindungsgemäßen Verpackungsmaschine hat den Vorteil, daß die jeweilige Arbeitsstation eine Einheit darstellt und insgesamt in der Verpackungsmaschine verschoben oder demontiert werden kann.In a preferred embodiment, the yokes are preferably at the bottom End of the rods preferably mounted vertically displaceable, each one Yoke is held by two poles. This embodiment of the Packaging machine according to the invention has the advantage that the respective Workstation represents a unit and overall in the packaging machine moved or dismantled.
Vorteilhafterweise ist an jeder Stange jeweils ein Federelement, vorzugsweise eine Elastomerfeder, angebracht, auf denen die vertikal verschieblichen Jochs aufliegen. Diese Ausführungsform der erfindungsgemäßen Verpackungsmaschine hat den Vorteil, daß Folien mit unterschiedlicher Dicke oder mit einer relativ großen Toleranzen bezüglich der Dicke verarbeitet werden können, ohne daß Änderungen an der Einstellung des Hubes vorgenommen werden müssen. Eine Vergrößerung der Foliendicke resultiert dann in einer minimalen Krafterhöhung. Darüber hinaus kann durch die Federn der Anpreßdruck des Unterwerkzeuges gegen das Oberwerkzeug begrenzt werden.Advantageously, a spring element, preferably one, is provided on each rod Elastomer spring mounted on which rest the vertically displaceable yokes. This embodiment of the packaging machine according to the invention has the advantage that films with different thickness or with a relatively large tolerances can be processed in thickness without changes to the Adjustment of the stroke must be made.

The electric motor or the transmission preferably has such a high Torque and such a high rotational speed that the plate with the Lower tool within less than a second, preferably within less than half a second from the bottom to the top position and is raised or lowered vice versa.
Darüber hinaus weist der Elektromotor bzw. das Getriebe abtriebsseitig vorzugsweise ein Haltemoment von > 50 Nm besonders bevorzugt > 100 Nm auf, um die Kräfte, die z.B. beim Siegeln oder Schneiden auftreten, wenn die Stange, die die Platte mit der Kurbelwelle verbindet nicht sekrecht steht, aufnehmen zu können.In addition, the electric motor or the transmission preferably has on the output side a holding torque of> 50 Nm particularly preferably> 100 Nm to the forces that e.g. When sealing or cutting occur when the rod, the plate with the Crankshaft does not connect Seconds is able to record.
Die Kurbelwelle wird im Wechsel im und gegen den Uhrzeigersinn gedreht. Diese Anordnung hat sich überraschender Weise als sehr platzsparend herausgestellt. Dabei beträgt der Drehwinkel maximal 180°. Vorzugsweise führt die Kubelwelle jedoch einen Drehwinkel aus, der gerade so groß ist, daß das Werkzeug die Verpackungsmulde bei deren Weitertransport nicht beschädigt. Besonders bevorzugt wird das Werkzeug soweit abgesenkt, daß sich dessen Oberkannte im abgesenkten Zustand maximal 1-10 mm unterhalb der Verpackungsmulde befindet. Durch diese Absenkung kann die Taktzeit der erfindungsgemäßen Verpackungsmaschine entscheidend verkürzt werden.The crankshaft is alternately rotated clockwise and counterclockwise.

Due to the fact that the rod is in the middle of the plate attacks is tilting the plate on the guide locked out.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Verpackungsmaschine weist diese ein Mittel zur Vermeidung von Produktquetschungen zwischen Ober- und Unterwerkzeug auf. Vorzugsweise ist dieses Mittel eine Begrenzung des zulässigen Stromverbrauche, der zur Aufwärtsbewegung des Unterteils benötigt wird. Falls sich zwischen Ober- und Unterwerkzeug Produkt befinden sollte, wird dies zwischen Unter- und Oberwerkzeug zusammengedrückt. Dabei steigt der Stromverbrauch, der benötigt wird, um das Unterwerkzeug anzuheben und die Steuerung des Motors stoppt die Aufwärtsbewegung.In a preferred embodiment of the invention Packaging machine has this means of avoidance Product crushing between upper and lower tool. Preferably this means a limit on the allowable power consumption used to Upward movement of the lower part is needed. If between upper and This should be between lower and lower tool product Compressed upper tool. This increases the power consumption that is needed is to lift the lower tool and the control of the engine stops the Upward movement.
