Die ersten Stange 17 und die zweite Stange 18 sind jeweils mit ersten Befestigungselementen 19 bzw. mit zweiten Befestigungselementen 20 (siehe Fig. 3b) mit den Querträgern 15, 16 verbunden. Die erste Stange 17 und die zweite Stange 18 erstrecken sich in vertikaler Richtung nach oben und enden jeweils in einer ersten Hängevorrichtung 21 bzw. in einer zweiten Hängevorrichtung 22. Diese Hängevorrichtungen 21, 22 sind mit dem Maschinengestell der Verpackungsmaschine verbindbar.The first cross member 15 and the second cross member 16 (see Fig. 3b ) each have a vertical central bore which receives a first rod 17 and a second rod 18, respectively. The first rod 17 and the second rod 18 are each provided with first fastening elements 19 and second fastening elements 20 (see FIG Fig. 3b ) connected to the cross members 15, 16. The first rod 17 and the second rod 18 extend in vertical Direction upward and end respectively in a first hanger 21 and in a second hanger 22. These hangers 21, 22 are connected to the machine frame of the packaging machine.

Ein Motor 8 in Form eines Elektromotors, bzw. ein nachgeschaltetes Getriebe 9 ist über einen Getriebeflansch 10 mit dem ersten Träger 11 verbunden. Der Motor 8 treibt über das Getriebe 9 den ersten Antriebszapfen 62 (siehe Fig. 2a, b) an, der drehfest mit dem ersten Hebels 61 verbunden ist. Der erste Hebel 61 schließt zusammen mit einem Hebelgegenstück 61a, das über den Drehzapfen 63 drehfest mit dem ersten Hebel 61 verbunden ist, eine Rolle 32 ein. Die Rotationsachse der Rolle 32 liegt in der selben Achse wie die Achse des ersten Drehzapfens 63, der die Welle der beispielsweise kugelgelagerten Rolle 32 bildet. Die Rolle 32 in einer kreisförmigen Bewegung um die Achse des ersten Antriebszapfens 62 bewegbar. Die Rolle 32 wird durch eine obere Rollenbegrenzung 33 und eine untere Rollenbegrenzung 34 begrenzt. Die obere Rollenbegrenzung 33 und die untere Rollenbegrenzung 34 sind durch einen ersten Verbindungsbolzen 35 und einen zweiten Verbindungsbolzen 36 miteinander verbunden. Das Hebelgegenstück 61a verhindert zusammen mit dem ersten Hebel 61 im Betrieb ein Verrutschen der Rolle 32 in Richtung ihrer Rotationsachse. Außerdem kann sich der erste Hebel 61 durch diese Konstruktion 360° um den ersten Antriebszapfen 62 drehen. Durch die beiden Rollenbegrenzungen 33, 34, sowie den in sich geschlossenen Kraftfluss der Konstruktion ist eine Anheb- sowie eine Absenkkraft auf die jeweilige Arbeitsstation übertragbar.A motor 8 in the form of an electric motor, or a downstream transmission 9 is connected via a transmission flange 10 to the first carrier 11. The motor 8 drives via the gear 9, the first drive pin 62 (see Fig. 2a, b ), which is non-rotatably connected to the first lever 61. The first lever 61, together with a lever counterpart 61a, which is rotatably connected via the pivot pin 63 with the first lever 61, a roller 32 a. The axis of rotation of the roller 32 is in the same axis as the axis of the first pivot 63, which forms the shaft of the ball-bearing roller 32, for example. The roller 32 is movable in a circular movement about the axis of the first drive pin 62. The roller 32 is bounded by an upper roller limit 33 and a lower roller limit 34. The upper roller limit 33 and the lower roller limit 34 are connected to each other by a first connecting pin 35 and a second connecting pin 36. The lever counterpart 61a prevents together with the first lever 61 in operation slipping of the roller 32 in the direction of its axis of rotation. In addition, the first lever 61 can rotate 360 ° about the first drive pin 62 by this construction. Due to the two roller boundaries 33, 34, as well as the self-contained force flow of the construction, a lifting and a lowering force can be transmitted to the respective workstation.

Die obere Rollenbegrenzung 33 weist weiterhin eine Rollenführung 331 auf, die direkten Kontakt mit der Rolle 32 hat. Diese Rollenführung 331 ist in dieser Ausführungsform plan ausgebildet. Es ist aber auch denkbar, dass die Rollenführung 331 zumindest teilweise an einem Ende als Kurvenform gebildet ist. Auf diese Weise ist beim Betrieb der erfindungsgemäßen Vorrichtung in der Endphase der Hubbewegung eine weitere Anhebung der jeweiligen anzuhebenden Arbeitsstation der Verpackungsmaschine realisierbar. Durch eine leichte Anschrägung der Rollenführung 331 kann
so bei geringer Hubbewegung eine große Kraft übertragen werden, um beispielsweise ein Siegelwerkzeug anzupressen.The upper roller limit 33 further comprises a roller guide 331, which has direct contact with the roller 32. This roller guide 331 is planar in this embodiment. But it is also conceivable that the roller guide 331 at least partially formed at one end as a curve shape. In this way, during operation of the device according to the invention in the final phase of the lifting movement, a further increase of the respective workstation to be lifted of the packaging machine can be realized. By a slight bevel of the roller guide 331 can
so a large force can be transmitted at low stroke movement, for example, to press a sealing tool.

Die gesamte Anordnung der oberen Rollenbegrenzung 33, der unteren Rollenbegrenzung 34, des ersten Verbindungsbolzens 35 und des zweiten Verbicoungsbolzens 36 ist über die obere Rollendegrenzung 33 mit einem fünften Träger 31 verbunden, der wiederum vertikal verschiebbar ausgeführt ist. Zu diesem Zweck ist der fünfte Träger 31 in der Form eines Balkens gebildet und weist an seinen beiden Enden jeweils eine vertikale Durchgangsbohrung auf. Der fünfte Träger 31 bzw. mit ihm die obere Rollenbegrenzug 33 und die untere Rollenbegrenzung 34 sind über die erste Stange 17 bzw. die zweite Stange 18 geführt bzw. vertikal verschiebbar. Zusätzlich zur Führung durch den fünften Träger 31 sind an beiden Stangen jeweils ein erstes Gleitlager 23 und ein zweites Gleitlager 24 vorgesehen, die im Wesentlichen die Form eines Hohlzylinders aufweisen und an ihrem oberen Ende mit der Unterseite des fünften Trägers 31 abschließen. Mit dem fünften Träger 31 verbunden sind ein erstes Unterteilverbindungselement 25 und ein zweites Unterteilverbindungselement 26, die zum Verbinden der Hubvorrichtung 100 mit der jeweiligen Arbeitsstation der Verpackungsmaschine dienen.The entire arrangement of the upper roller limit 33, the lower roller boundary 34, the first connecting pin 35 and the second Verbicoungsbolzens 36 is connected via the upper roller limit 33 with a fifth carrier 31, which in turn is designed to be vertically displaceable. For this purpose, the fifth carrier 31 is formed in the form of a beam and has at its two ends in each case a vertical through hole. The fifth carrier 31 or with it the upper Rollenbegrenzug 33 and the lower roller boundary 34 are guided over the first rod 17 and the second rod 18 and vertically displaceable. In addition to the guide through the fifth carrier 31, a first slide bearing 23 and a second slide bearing 24 are provided on both rods, which essentially have the shape of a hollow cylinder and terminate at its upper end with the underside of the fifth carrier 31. Connected to the fifth carrier 31 are a first base connector 25 and a second bottom connector 26 which serve to connect the elevator 100 to the respective workstation of the packaging machine.

Fig. 3b zeigt eine Rückansicht der in Fig. 3a beschriebenen Vorrichtung. Die durch den Motor 8 erzeugte Rotationsbewegung wird im Betrieb durch den ersten Hebel 61 bzw. die Rolle 32 in eine translatorische Bewegung gewandelt. Die bewegliche Baugruppe, die aus der oberen Rollenbegrenzung 33 bzw. der Rollenführung 331, der unteren Rollenbegrenzung 34, dem ersten Verbindungsbolzen 35, dem zweiten Verbindungsbolzen 36, dem fünften Träger 31, dem ersten Unterteilverbindungselement 25 und dem zweiten Unterteilverbindungselement 26 bzw. den beiden Gleitlagern 23, 24
besteht, wird über die erste Stange 17 bzw. die zweite Stange 18 angehoben bzw. abgesenkt, um die betreffende Arbeitsstation, wie z.B. den Deckel 5 oder eine Form-, Siegel- oder Schneidstation anzuheben bzw. abzusinken. Fig. 3b shows a rear view of the in Fig. 3a described device. The rotational movement generated by the motor 8 is converted in operation by the first lever 61 and the roller 32 in a translational movement. The movable assembly, the upper roller limit 33 or the roller guide 331, the lower roller limit 34, the first connecting pin 35, the second connecting pin 36, the fifth carrier 31, the first lower part connecting element 25 and the second lower part connecting element 26 and the two plain bearings 23, 24th
is raised or lowered via the first rod 17 and the second rod 18 to raise or lower the relevant work station, such as the cover 5 or a forming, sealing or cutting station.

Fig. 4a zeigt eine zweite Ausführungsform der vorliegenden Erfindung, insbesondere für Arbeitsstationen in einer Tiefziehmaschine oder Schalenverschließmaschinen, wie z.B. Formstationen, Siegelstationen und/oder Schneidstationen. Es ist eine Basisplatte 37 mit einer Vielzahl von vertikal angeordneten Messlöchern 38 vorgesehen, die zusammen mit einem Sensor als Messvorrichtung dienen. Der Motor 8 ist über ein Getriebe 9 bzw. einen Getriebeflansch 10 mit der Basisplatte 37 verbunden. Weiterhin sind eine erste Linearführungsrollenaufnahme 43 und eine zweite Lineariührungsrollenaufnahme 44 bzw. eine dritte Linearführungsrollenaufnahme 45 und eine vierte Linearführungsrollenaufnahme 46 mit der Basisplatte 37 verbunden, wobei die erste und die zweite Linearführungsrollenaufnahme 43, 44 jeweils zwei Linearführungsrollen 47 tragen und die dritte Linearführungsrollenaufnahme 45 und die vierte Linearführungsrollenaufnahme 46 jeweils eine Linearführungsrolle 47 tragen. Zwischen den beiden Linearführungsrolle 47 der ersten und der zweiten Linearführungsrollenaufnahme 43, 44 sind jeweils, d.h. auf beiden Seiten der Basisplatte 37 eine erste Linearführung 39 und eine zweite Linearführung 40 vertikal verschiebbar angeordnet. Jeweils am oberen Ende der ersten Linearführung 39 und der zweiten Linearführung 40 sind erste Linearführungsbefestigungselemente 41 bzw. zweite Linearbefestigungselemente 42 vorgesehen, die zur Verbindung der jeweiligen Arbeitsstation der Verpackungsmaschine dienen, die eine Hubbewegung ausführen soll. Fig. 4a shows a second embodiment of the present invention, in particular for workstations in a thermoforming machine or tray sealing machines, such as forming stations, sealing stations and / or cutting stations. There is provided a base plate 37 with a plurality of vertically arranged measuring holes 38, which serve together with a sensor as a measuring device. The motor 8 is connected via a gear 9 and a gear flange 10 with the base plate 37. Furthermore, a first linear guide roller receptacle 43 and a second Lineariührungsrollenaufnahme 44 and a third linear guide roller receptacle 45 and a fourth linear guide roller receptacle 46 are connected to the base plate 37, wherein the first and second linear guide roller receptacle 43, 44 each carry two linear guide rollers 47 and the third linear guide roller receptacle 45 and fourth linear guide roller receptacle 46 each carry a linear guide roller 47. Between the two linear guide roller 47 of the first and second linear guide roller receptacle 43, 44 are respectively, that is arranged on both sides of the base plate 37, a first linear guide 39 and a second linear guide 40 vertically slidably. In each case at the upper end of the first linear guide 39 and the second linear guide 40 are first linear guide fasteners 41 and second Linear fastening elements 42 are provided which serve to connect the respective workstation of the packaging machine, which is to perform a lifting movement.

Fig. 4b zeigt die in Fig. 4a beschriebene Anordnung der zweiten Ausführungsform der vorliegenden Erfindung in einer perspektivischen Rückansicht. Die Getriebeabtriebswelle (nicht gezeigt) des Getriebes 9 treibt den ersten Antriebszapfen 62' an. Zu diesem Zweck ist eine kreisförmige Bohrung in der Basisplatte 37 vorgesehen, durch die der ersten Antriebszapfen 62' hindurch tritt. An dem ersten Antriebszapfen 62' ist der erste Hebel 61' drehfest befestigt, und nimmt an seinem anderen Ende die Rolle 32' auf. Diese Rolle 32' wirkt im Betrieb mit der oberen Rollendegrenzung 33' zusammen. Die obere Rollenbegrenzung 33' ist mit einem Linearführungsverbindungselement 48 verbunden, das mit der ersten Linearführung 39 bzw. der zweiten Linearführung 40 verbunden ist. Die gesamte Baugruppe bestehend aus der ersten Linearführung 39, der zweiten Linearführung 40 und der oberen Rollenbegrenzung 33' ist in vertikaler Richtung verschiebbar. Hierbei wird sie durch die Linearführungsrollen 47 geführt. Da hier nur die obere Rollenbegrenzung 33' realisiert ist, kann eine Kraft nur beim Anheben der jeweiligen Arbeitsstation übertragen werden. Die Absenkbewegung der Arbeitsstation erfolgt durch die Gewichtskraft der Arbeitsstation. Dadurch kann die untere Rollenbegrenzung 34 (siehe Fig. 3a, b) entfallen. Fig. 4b shows the in Fig. 4a described arrangement of the second embodiment of the present invention in a perspective rear view. The transmission output shaft (not shown) of the transmission 9 drives the first drive pin 62 '. For this purpose, a circular bore is provided in the base plate 37, through which the first drive pin 62 'passes. On the first drive pin 62 ', the first lever 61' is rotatably attached, and receives at its other end the roller 32 '. This roller 32 'acts in operation with the upper roller limit 33' together. The upper roller boundary 33 'is connected to a linear guide connecting element 48 which is connected to the first linear guide 39 and the second linear guide 40, respectively. The entire assembly consisting of the first linear guide 39, the second linear guide 40 and the upper roller limit 33 'is displaceable in the vertical direction. In this case, it is guided by the linear guide rollers 47. Since only the upper roller limit 33 'is realized here, a force can only be transmitted when lifting the respective workstation. The lowering of the workstation is done by the weight of the workstation. This allows the lower roll limit 34 (see Fig. 3a . b ) accounted for.

Es ist denkbar zusätzliche Linearführungen zur besseren Stabilität der Hubvorrichtung 100 vorzusehenIt is conceivable to provide additional linear guides for better stability of the lifting device 100

Fig. 5a zeigt in einer schematischen Vorderansicht die Hebelvorrichtung 6, die in dieser Ausführungsform mittig angeordnet ist, d.h. dass der ortsfeste erste Antriebszapfen 62 mittig unter dem Deckel 5 angeordnet ist. Der Angriffspunkt des ersten Drehzapfens 63 ist nur in der untersten, sowie in der obersten Stellung mittig. In der gezeigten Stellung der Hubvorrichtung befindet sich der erste Hebel 61 bzw. der erste Drehzapfen 63 auf einer Zwischenstellung. In dieser Stellung ist der Kraftangriffspunkt maximal verschoben. Durch den Hebel XV wirkt ein Kippmoment auf die Hubvorrichtung. Fig. 5a shows in a schematic front view of the lever device 6, which is arranged centrally in this embodiment, ie, that the stationary first drive pin 62 is arranged centrally below the cover 5. The point of application of the first pivot 63 is centered only in the lowest and in the highest position. In the illustrated position of the lifting device, the first lever 61 and the first pivot 63 is at an intermediate position. In this position, the force application point is shifted maximum. The lever X V causes a tilting moment on the lifting device.

Fig. 5b zeigt den gleichen Aufbau wie in Fig. 5a, mit der Ausnahme, dass die Hebelvorrichtung 6 exzentrisch angeordnet ist. Auf diese Weise kann der Kraftangriffspunkt in dieser MittelStellung des ersten Hebels 61 verschoben werden und somit der wirksame Hebelarm XV und das daraus resultierende Kippmoment, das auf die Hubvorrichtung 100 wirkt, reduziert werden. Der Drehpunkt des ersten Antriebszapfens 62 kann im Wesentlichen um die halbe Länge des ersten Hebels 61 außermittig verschoben werden, was eine Halbierung des resultierenden Moments zur Folge hat. Vorteilhafterweise führt der erste Hebel 61 eine 180° - Drehung aus, abhängig von der Verschiebung des ersten Antriebszapfens 62 nach links oder rechts. Fig. 5b shows the same structure as in Fig. 5a with the exception that the lever device 6 is arranged eccentrically. In this way, the force application point can be moved in this center position of the first lever 61 and thus the effective lever arm X V and the resulting tilting moment, which acts on the lifting device 100 can be reduced. The fulcrum of the first drive pin 62 can be displaced eccentrically substantially by half the length of the first lever 61, resulting in a halving of the resulting moment result. Advantageously, the first lever 61 performs a 180 ° rotation, depending on the displacement of the first drive pin 62 to the left or right.

Fig. 6a zeigt in einer weiteren Ausführungsform der vorliegenden Erfindung eine doppelte Hebelvorrichtung 6' mit dem ersten Hebel 61, dem ersten Antriebszapfen 62, dem ersten Drehzapfen 63, einem zweiten Hebel 64, einem zweiten Antriebszapfen 65 und einem zweiten Drehzapfen 66. Auf diese Weise werden Kippmomente, die auf die Hubvorrichtung 100 wirken, während des Betriebs eliminiert, da sie sich bei gleicher Verschiebung des ersten Antriebszapfens 62 und des zweiten Antriebszapfens 65 gegenseitig aufheben. Der Betrieb dieser Ausführungsform (siehe Fig. 6a,b,c) erfolgt analog zu dem bezüglich Fig. 2a,b beschriebenen Betrieb. Der Deckel 5 befindet sich in einer abgesenkten Position. Fig. 6a shows in a further embodiment of the present invention, a double lever device 6 'with the first lever 61, the first drive pin 62, the first pivot 63, a second lever 64, a second drive pin 65 and a second pivot 66. In this way, tilting moments, which act on the lifting device 100, eliminated during operation, since they cancel each other with the same displacement of the first drive pin 62 and the second drive pin 65. The operation of this embodiment (see Fig. 6a, b, c ) takes place analogously to the respect Fig. 2a, b described operation. The lid 5 is in a lowered position.

Fig. 6b zeigt den Deckel 5 in einer mittleren Position. Fig. 6b shows the lid 5 in a middle position.

Fig. 6c zeigt den Deckel 5 in einer angehobenen Position. Fig. 6c shows the lid 5 in a raised position.

Fig. 7 zeigt einen ähnlichen Aufbau wie in Fig. 3a, mit der Ausnahme, dass der erste Drehzapfen 63 mit einer Pleuelstange 67 verbunden ist, die zwischen einem dritten Träger 13 und einem vierten Träger 14 gelagert ist. Der dritte Träger 13 und der vierte Träger 14 bzw. das erste Gleitlager 23' und das zweite Gleitlager 24' erfüllen die selbe. Funktion, wie der fünfte Träger 31 bzw. das erste Gleitlager 23 und das zweite Gleitlager 24 (siehe Fig. 3a). Der Motor 8 bzw. das Getriebe 9 und der Getriebeflansch 10 sind in dieser Ausführungsform horizontal zum Boden ausgerichtet. In dieser Ausführungsform wirken in allen Zwischenstellungen, in denen die Pleuelstange 67 nicht exakt vertikal ausgerichtet ist, Querkräfte auf die Hubvorrichtung 100. Fig. 7 shows a similar structure as in Fig. 3a with the exception that the first pivot 63 is connected to a connecting rod 67 which is mounted between a third carrier 13 and a fourth carrier 14. The third carrier 13 and the fourth carrier 14 or the first sliding bearing 23 'and the second sliding bearing 24' fulfill the same. Function, as the fifth carrier 31 and the first sliding bearing 23 and the second sliding bearing 24 (see Fig. 3a ). The motor 8 and the gear 9 and the gear flange 10 are aligned horizontally to the ground in this embodiment. In this embodiment, transverse forces act on the lifting device 100 in all intermediate positions in which the connecting rod 67 is not aligned exactly vertically.
