Description

Verpackungsmaschine mit einem regelbaren Pneumatik/Hydraulik-Antrieb Packaging machine with a controllable pneumatic / hydraulic drive
Die vorliegende Erfindung betrifft eine Verpackungsmaschine, bei der mindestens ein Werkzeug mit einem Hubsystem in eine abgesenkte und in eine angehobene Stellung verschiebbar ist, wobei die Hubstation als Antrieb mindestens einen regelbaren Pneumatik/Hydraulik-Antrieb aufweist.The present invention relates to a packaging machine in which at least one tool with a lifting system is displaceable in a lowered and in a raised position, wherein the lifting station has at least one controllable pneumatic / hydraulic drive as a drive.
Heutzutage werden Lebensmittel oftmals in Kunststoffverpackungen verpackt, um diese haltbar zu machen. Das Herstellen und Befüllen der Verpackungen geschieht in der Regel mit einer semikontinuierlich arbeitenden Verpackungsmaschine, bei der die Verpackungsmulde zunächst aus einer Folie tiefgezogen, sodann mit dem zu verpackenden Gut befüllt und anschließend mit einer Deckelfolie versiegelt wird. Die so hergestellten Verpackungen werden in einem letzten Schnitt auseinander geschnitten. Bei der Herstellung der Verpackung müssen Werkzeuge, beispielsweise die Tiefziehform, das Siegel- und/oder Schneidwerkzeug vertikal bewegt werden, wobei insbesondere beim Siegeln und Schneiden ganz erhebliche Kräfte auftreten. Der Antrieb der oben genannten Werkzeuge erfolgte oftmals mit Pneumatikzylindern, weil diese einfach und günstig zu handhaben sind.Nowadays, food is often packaged in plastic packaging to preserve it. The production and filling of the packaging is usually done with a semi-continuous packaging machine, in which the packaging tray is first deep-drawn from a film, then filled with the goods to be packaged and then sealed with a lidding film. The packages produced in this way are cut apart in a final cut. In the manufacture of the packaging tools, such as the thermoforming mold, the sealing and / or cutting tool must be moved vertically, in particular during sealing and cutting quite considerable forces occur. The drive of the above tools was often done with pneumatic cylinders, because they are easy and inexpensive to handle.
Es war die Aufgabe der vorliegenden Erfindung eine Verpackungsmaschine zur Verfügung zu stellen, die schneller und geräuschärmer ist sowie weniger Verschleiß aufweist als Maschinen gemäß dem Stand der Technik.It was the object of the present invention to provide a packaging machine which is faster and quieter and has less wear than state-of-the-art machines.
Gelöst wird die Aufgabe erfindungsgemäß mit einer Verpackungsmaschine, bei der mindestens ein Werkzeug mit einer Hubstation in eine abgesenkte und in eine angehobene Stellung verschiebbar ist, wobei die Hubstation als Antrieb mindestens einen regelbaren Pneumatik/Hydraulik-Antrieb aufweist.The object is achieved according to the invention with a packaging machine in which at least one tool with a lifting station in a lowered and in a raised position is displaceable, wherein the lifting station has at least one controllable pneumatic / hydraulic drive as drive.
Es war für den Fachmann überaus erstaunlich und nicht zu erwarten, dass diese Verpackungsmaschine wesentlich schneller arbeitet und weniger Geräusche verursacht als Verpackungsmaschinen nach dem Stand der Technik. Darüber hinaus ist die erfindungsgemäße Verpackungsmaschine weniger wartungsintensiv als die Verpackungsmaschinen des Standes der Technik. Erfindungsgemäß weist die Verpackungsmaschine als Antrieb für zumindest einige der darin vorhandenen Werkzeuge einen regelbaren Pneumatik- und/oder Hydraulik- Antrieb auf. Dieser Pneumatik- und/oder Hydraulik-Antrieb weist einen Zylinder und eine Antriebesstange auf. Der Zylinder oder die Stande sind mit dem Werkzeug direkt oder indirekt verbunden. Der Zylinder und die Stange können fest oder beweglich mit dem Rahmen der Verpackungsmaschine oder mit dem Untergrund, auf dem die Verpackungsmaschine steht, verbunden sein. Da der Pneumatik- und/oder Hydraulik-Antrieb regelbar ist, ist der Weg, die Geschwindigkeit und/oder die Beschleunigung der Antriebsstange und/oder des Zylinders regelbar. Das jeweilige Werkzeug legt demnach einen ganz bestimmten Weg zurück und die Geschwindigkeit ist zu jedem Zeitpunkt des Weges regelbar, wobei die Geschwindigkeit nicht konstant ist. Dadurch ist es beispielsweise möglich, dass das von dem Pneumatik- und/oder Hydraulik-Antrieb angetriebene Werkzeug den größten Teil seines Weges mit einer sehr hohen Geschwindigkeit zurücklegen und in seine Endlage sanft verfährt.It was extremely surprising and unexpected to those skilled in the art that this packaging machine works much faster and produces less noise than prior art packaging machines. In addition, the packaging machine according to the invention is less maintenance-intensive than the packaging machines of the prior art. According to the invention, the packaging machine as a drive for at least some of the tools present therein on a controllable pneumatic and / or hydraulic drive. This pneumatic and / or hydraulic drive has a cylinder and a drive rod. The cylinder or the stands are connected directly or indirectly to the tool. The cylinder and the rod may be fixedly or movably connected to the frame of the packaging machine or to the substrate on which the packaging machine stands. Since the pneumatic and / or hydraulic drive can be regulated, the travel, the speed and / or the acceleration of the drive rod and / or the cylinder can be regulated. The respective tool therefore sets a very specific path and the speed can be regulated at any point in time, whereby the speed is not constant. As a result, it is possible, for example, for the tool driven by the pneumatic and / or hydraulic drive to cover most of its travel at a very high speed and to move it gently into its end position.
Der Pneumatik- und/oder Hydraulik-Antrieb kann jedes beliebige Getriebe antreiben, beispielsweise ein Kurbel-, Kurven- oder Gelenkgetriebe sowie eine Kombination aus diesen Getriebearten. In einer bevorzugten Ausführungsform der erfindungsgemäßen Verpackungsmaschine treibt der Pneumatik- und/oder Hydraulik-Antrieb ein Kniehebelsystem an, dass wiederum die auf und ab Bewegung der jeweiligen Werkzeuge bewirkt.The pneumatic and / or hydraulic drive can drive any gear, such as a crank, cam or linkage and a combination of these types of gears. In a preferred embodiment of the packaging machine according to the invention, the pneumatic and / or hydraulic drive drives a toggle lever system, which in turn causes the up and down movement of the respective tools.
Ein Werkzeug im Sinne der Erfindung ist jedes Werkzeug, das zur Herstellung einer Verpackung dient und das auf und ab bewegt werden muss. Beispielsweise ist das Werkzeug eine Tiefziehform, ein Siegelwerkzeug und/oder ein Schneidwerkzeug. Ein Werkzeug im Sinne der Erfindung kann sich unter- und/oder oberhalb der Folienbahn, aus der die Verpackungsmulde hergestellt wird, befinden. Ein Pneumatik- und/oder Hydraulik-Antrieb kann sowohl das Unter- als auch das Oberwerkzeug einer Arbeitsstation zeitgleich oder nacheinander bewegen. Der Pneumatik- und/oder Hydraulik-Antrieb kann auf jede dem Fachmann bekannte Art und Weise gesteuert werden. Vorzugsweise wird der Druck des Pneumatik- und/oder Hydraulik-Antriebs geregelt. In Phasen, in denen sich der Pneumatik- und/oder Hydraulik-Antrieb schnell bewegen soll, herrscht deshalb ein hoher Druck der dann beispielsweise vor Erreichen einer Endlage reduziert wird.A tool according to the invention is any tool that is used to make a package and that must be moved up and down. For example, the tool is a thermoforming mold, a sealing tool and / or a cutting tool. A tool according to the invention may be located below and / or above the film web from which the packaging tray is made. A pneumatic and / or hydraulic drive can move both the lower and the upper tool of a workstation at the same time or in succession. The pneumatic and / or hydraulic drive can be controlled in any manner known to those skilled in the art. Preferably, the pressure of the pneumatic and / or hydraulic drive is regulated. In phases in which the pneumatic and / or hydraulic drive should move quickly, therefore, there is a high pressure is then reduced, for example, before reaching an end position.
Vorzugsweise weist der Pneumatik- und/oder Hydraulik-Antrieb einen Absolutweggeber auf, so dass insbesondere die Position des dem Antriebszylinder abgewandten Ende der Antriebsstange und damit die Position des Werkzeuges einer Steuerung der erfindungsgemäßen Verpackungsmaschine jederzeit genau bekannt ist. Dieses Signal wird zur Regelung der Bewegung des Werkzeuges herangezogen. Diese Regelung erlaubt nicht nur das Werkzeug zwischen zwei festen Endpunkten zu verschieben, sondern die angehobene bzw. abgesenkte Stellung beliebig einstellen zu können. Des weiteren ermöglicht dieser Antrieb, dass die Geschwindigkeit, mit der das jeweilige Werkzeug bewegt wird, zwischen den beiden Stellungen zu jedem Zeitpunkt gezielt einstellbar ist.Preferably, the pneumatic and / or hydraulic drive on Absolutweggeber, so that in particular the position of the drive cylinder facing away from the end of the drive rod and thus the position of the tool control of the packaging machine according to the invention is precisely known at all times. This signal is used to control the movement of the tool. This regulation allows not only to move the tool between two fixed endpoints, but to be able to set the raised or lowered position arbitrarily. Furthermore, this drive allows the speed at which the respective tool is moved to be selectively adjustable between the two positions at any time.
Eine Verpackungsmaschine im Sinne der Erfindung ist nicht nur ein Thermoformer, bei dem die Verpackungsmulde durch Tiefziehen hergestellt und dann befüllt und mit einer Deckelfolie versiegelt wird, sondern auch ein sogenannter Traysealer, bei dem bereits vorgeformte Verpackungsmulden mit einem Verpackungsgut gefüllt und danach mit einer Verpackungsfolie gesiegelt werden. Weiterhin ist eine Verpackungsmaschine im Sinne der Erfindung auch ein sogenannter Trayformer, bei dem lediglich Verpackungsmulden aus einer Folie tiefgezogen und danach auseinander geschnitten werden.A packaging machine according to the invention is not only a thermoformer in which the packaging tray is produced by deep drawing and then filled and sealed with a lidding film, but also a so-called tray sealer, filled in the already preformed packaging trays with a packaged goods and then sealed with a packaging film become. Furthermore, a packaging machine in the context of the invention is also a so-called tray former, in which only packaging trays are deep-drawn from a film and then cut apart.
Im folgenden wird die Erfindung anhand der Figuren 1 und 6 erläutert. Diese Erläuterungen sind lediglich beispielhaft.In the following the invention will be explained with reference to Figures 1 and 6. These explanations are merely exemplary.
Figur 1 zeigt den prinzipiellen Aufbau einer Tiefziehverpackungsmaschine.Figure 1 shows the basic structure of a thermoforming packaging machine.
Figur 2 zeigt eine Seitenansicht einer Arbeitsstation mit einem Kniehebelsystem in angehobener Position. Figur 3 zeigt eine Vorderansicht einer Arbeitsstation mit einem Kniehebelsystem in angehobener Position.Figure 2 shows a side view of a workstation with a toggle lever system in the raised position. Figure 3 shows a front view of a workstation with a toggle lever system in the raised position.
Figur4 zeigt eine Draufsicht einer Arbeitsstation.Figure 4 shows a plan view of a workstation.
Figur 5 zeigt eine perspektivische Ansicht des Kniebehebelsystems.FIG. 5 shows a perspective view of the knee lever system.
Figur 6 zeigt zwei bezogen auf die Laufrichtung, hintereinander angeordnete Kniehebelhubsysteme.FIG. 6 shows two toggle lifting systems arranged one after the other in relation to the running direction.
Figur 1 zeigt eine schematische Darstellung einer möglichen Ausführungsform der erfindungsgemäßen Verpackungsmaschine 59. Eine Unterfolie 42 wird von einer Rolle abgerollt und zunächst mit einem Heizelement erwärmt. Nachfolgend wird die Unterfolie in einer Formstation 43 tiefgezogen. Diese Formstation 43 weist ein Oberwerkzeug 44 und ein Unterwerkzeug 45 auf. Wie durch den Doppelpfeil dargestellt, der ein Hubsystem symbolisieren soll, ist das Unterwerkzeug 45 vertikal verschiebbar. Diese Hubsystem weist einen regelbaren Pneumatik- und/oder Hydraulik-Antrieb auf. Dadurch kann der Weg, die Geschwindigkeit während des Weges und die Beschleunigung zu jedem Zeitpunkt geregelt werden. Die Geschwindigkeit, mit der das Werkzeug bewegt wird, ist nicht konstant. Beispielsweise wird das Werkzeug am Anfang des Weges stark beschleunigt, behält eine hohe Geschwindigkeit möglichst lange bei, um dann so abgebremst zu werden, dass es seine Endlage möglichst sanft erreicht. Die Endlagen zwischen denen sich das jeweilige Werkzeug bewegt sind ebenfalls frei wählbar. Der Pneumatik- und/oder Hydraulik-Antrieb wird von einem Computer gesteuert. Der Fachmann erkennt, das der Pneumatik- und/oder Hydraulik-Antrieb 46 auch das Oberwerkzeug antrieben kann. Sobald die Verpackungsmulden 58 in die Unterfolienbahn 42 eingeformt sind, werden sie mit dem Verpackungsgut 54 befüllt. Anschließend bevor die Verpackungsmulden in die Siegelstation 48 gelangen, werden mittels einer Stanze 56 Löcher in die Unterfolie gestanzt, die für den Gasaustausch in der Verpackung innerhalb der Siegelstation benötigt werden. In der Siegelstation 48 wird eine OFIG. 1 shows a schematic representation of a possible embodiment of the packaging machine 59 according to the invention. A lower film 42 is unrolled from a roll and first heated with a heating element. Subsequently, the lower film is deep-drawn in a forming station 43. This forming station 43 has an upper tool 44 and a lower tool 45. As shown by the double arrow, which is to symbolize a lifting system, the lower tool 45 is vertically displaceable. This lifting system has a controllable pneumatic and / or hydraulic drive. This allows the path, the speed during the journey and the acceleration to be regulated at any time. The speed at which the tool is moved is not constant. For example, the tool at the beginning of the path is greatly accelerated, maintains a high speed as long as possible, and then slowed down so that it reaches its end position as gently as possible. The end positions between which the respective tool moves are also freely selectable. The pneumatic and / or hydraulic drive is controlled by a computer. The person skilled in the art recognizes that the pneumatic and / or hydraulic drive 46 can also drive the upper tool. Once the packaging troughs 58 are formed in the lower film web 42, they are filled with the packaged 54. Subsequently, before the packaging troughs reach the sealing station 48, holes are punched in the lower foil by means of a punch 56, which holes are required for the gas exchange in the packaging within the sealing station. In the sealing station 48 is a O
Oberfolie 55 auf die Unterfolie 42 gesiegelt und somit die Verpackungen geschlossen. Auch die Siegelstation weist ein Oberwerkzeug 49 und ein Unterwerkzeug 50 auf, die beim Siegeln gegeneinander gepresst werden. Das Unterwerkzeug 50 wird ebenfalls von einem Hubsystem 46 angetrieben. In dem Oberwerkzeug 49 befindet sich ein Siegelrahmen, der mittels eines Heizelementes beheizt wird. Die nunmehr geschlossenen Verpackungen werden abschließend in einer Schneidstation 51 vereinzelt. Die Querschneidung der Schneidstation weist ebenfalls ein Oberwerkzeug 52 und ein Unterwerkzeug 53 auf, wobei das Unterwerkzeug 53 wiederum vertikal mit einem Hubsystem 46 verschiebbar ist.Upper film 55 sealed to the lower film 42 and thus closed the packaging. The sealing station also has an upper tool 49 and a lower tool 50, which are pressed against each other during sealing. The lower tool 50 is also driven by a lifting system 46. In the upper tool 49 is a sealing frame, which is heated by a heating element. The now closed packages are finally singulated in a cutting station 51. The cross-cutting of the cutting station also has an upper tool 52 and a lower tool 53, wherein the lower tool 53 in turn is vertically displaceable with a lifting system 46.
Die Figuren 2- 4 zeigen eine Arbeitsstation 43, 48, 51 der erfindungsgemäße Verpackungsmaschinen mit einem Oberwerkzeug 44, 49, 52 und/oder einem Unterwerkzeug 45, 50, 53. Beide Werkzeuge sind, wie durch die Doppelpfeile dargestellt, anhebbar bzw. absenkbar. Die Arbeitsstation wird mittels der Rollen 7 in der Verpackungsmaschine gelagert und ist somit entlang der Verpackungsmaschine, insbesondere deren Rahmen, horizontal verschiebbar angeordnet. Dafür weist der Rahmen besonders bevorzugt zwei parallele horizontale Stangen auf, zwischen denen die Rollen angeordnet sind. Das Oberwerkzeug 44, 49, 52 ist starr mittels der Zugstangen 6 mit einem Rahmen 5 verbunden. Die Zugstangen 6 und damit das Oberwerkzeug 44, 49, 52 sowie der Rahmen 5 sind vertikal verschieblich gelagert, wobei deren Vertikalbewegung am inneren Umfang des Hohlkörpers 8, einem Rohr, geführt wird. Die Arbeitsstation der erfindungsgemäßen Verpackungsmaschine weist einen regelbaren Hydraulik- und/oder Pneumatikantrieb mit einem Zylinder 1 und einem Kolben 2 auf. Der Zylinder 1 stützt sich an seiner Oberseite an einem Gestell 3 ab, auf dem das Unterwerkzeug 45, 50, 53 montiert ist, während sich der Kolben 2 an einer Querstange 4, die mittels der Verbindungselemente 15 und der Schraube 21 an einem über die Rollen 7 mit dem Maschinenrahmen verbundenem Joch 19 angeordnet ist, abstützt. Das Gestell 3 weist Führungsbuchsen 9 auf, die mit dem äußeren Umfang der Hohlkörper 8, führend zusammenwirkt. Die Führung des Gestells 3 wird bei dessen auf und ab Bewegung benötigt. An dem Zylinder 1 ist ein Ende des Hebels 14 drehbar angeordnet. Dessen anderes Ende ist drehbar mit einem weiteren Hebel 13 verbunden. Dieser Hebel 13 ist wiederum drehfest an einer Welle 16 angeordnet, die drehbar in dem Joch 19 gelagert ist. Die Welle wird abwechselnd im und gegen den Uhrzeigersinn von dem Getriebe 13, 14 angetrieben. An dieser Welle 16 ist drehfest das Teil 11 eines Hebels angeordnet, der zwei Enden aufweist. An seinem einen Ende weist er ein weiteres Hebelelement 10 auf, das wiederum drehbar mit dem Gestell 3 verbunden ist. Die Hebel 10, 11 bilden einen Kniehebel. An seinem anderen Ende ist drehbar ein Ende eines weiterer Hebel 12 gelagert, dessen anderes Ende wiederum an dem Rahmen 5 drehbar angeordnet ist. Durch die Drehung der Welle 16 wird der Kniehebel 10, 11 von einer abgeknickten in eine gestreckte Stellung und umgekehrt überführt. Dasselbe gilt für den Hebel 12, der durch eine Drehung der Welle 16 von einer im Wesentlichen vertikalen in eine mehr horizontale Stellung überführt wird. Dabei hebt bzw. senkt der Hebel 12 den Rahmen 5 und damit die Stangen 6, die am inneren Umfang des Hohlkörpers 8 geführt werden, rauf und runter. Diese Stangen 6 sind mit dem Oberwerkzeug 44, 49, 52 verbunden, das dadurch ebenfalls gesenkt bzw. angehoben wird. Der Hohlkörper 8 ist mittels der Spannmutter 20 zwischen dem Rahmen 18 und dem Joch 19 eingespannt.

For this purpose, the frame particularly preferably has two parallel horizontal rods, between which the rollers are arranged. The upper tool 44, 49, 52 is rigidly connected by means of the tie rods 6 with a frame 5. The tie rods 6 and thus the upper tool 44, 49, 52 and the frame 5 are mounted vertically displaceable, wherein the vertical movement on the inner circumference of the hollow body 8, a pipe is guided. The workstation of the packaging machine according to the invention has a controllable hydraulic and / or pneumatic drive with a cylinder 1 and a piston 2. The cylinder 1 is supported on its upper side on a frame 3, on which the lower tool 45, 50, 53 is mounted, while the piston 2 on a crossbar 4, by means of the connecting elements 15 and the screw 21 at one on the rollers 7 is arranged connected to the machine frame yoke 19 is supported. The frame 3 has guide bushings 9, which cooperates with the outer circumference of the hollow body 8, leading. The leadership of the frame 3 is needed in its up and down movement. On the cylinder 1, one end of the lever 14 is rotatably arranged. Whose other end is rotatably connected to a further lever 13. This lever 13 is in turn rotatably mounted on a shaft 16 which is rotatably mounted in the yoke 19. The wave will alternately driven clockwise and counterclockwise by the transmission 13, 14. At this shaft 16, the part 11 of a lever is rotatably disposed, which has two ends. At one end, it has a further lever element 10, which in turn is rotatably connected to the frame 3. The levers 10, 11 form a toggle. At its other end one end of a further lever 12 is rotatably mounted, the other end is in turn rotatably mounted on the frame 5. By the rotation of the shaft 16 of the toggle 10, 11 is transferred from a bent into an extended position and vice versa. The same applies to the lever 12, which is transferred by a rotation of the shaft 16 from a substantially vertical to a more horizontal position. Here, the lever 12 raises or lowers the frame 5 and thus the rods 6, which are guided on the inner circumference of the hollow body 8, up and down. These rods 6 are connected to the upper tool 44, 49, 52, which is thereby also lowered or raised. The hollow body 8 is clamped by means of the clamping nut 20 between the frame 18 and the yoke 19. With the adjusting means 22, the stroke of the lifting element can be adjusted.
In den Figuren 2 und 4 ist das Hubsystem der erfindungsgemäßen Verpackung in einem Zustand gezeigt, in dem sich das Gestell 3 und damit das Unterwerkzeug 45, 50, 53 in seiner obersten und das Oberwerkzeug 44, 49, 52 in seiner untersten Stellung befindet. Durch eine Drehung der Welle 16 im Uhrzeigersinn wird das Kniehebelsystem 10, 11 geknickt und damit das Gestell 3 abgesenkt bzw. der Rahmen 5 angehoben, so dass sich die beiden Werkzeuge 24, 25 auseinander bewegen.In Figures 2 and 4, the lifting system of the package according to the invention is shown in a state in which the frame 3 and thus the lower tool 45, 50, 53 in its uppermost and the upper tool 44, 49, 52 is in its lowermost position. By a rotation of the shaft 16 in the clockwise direction, the toggle lever system 10, 11 is bent and thus the frame 3 is lowered or raised the frame 5, so that the two tools 24, 25 move apart.
Figur 5 zeigt die Arbeitsstation gemäß den Figuren 1 bis 3 in einer perspektivischen Darstellung.Figure 5 shows the workstation according to Figures 1 to 3 in a perspective view.
In Figur 6 ist eine Arbeitsstation dargestellt, die zwei Hubsysteme gemäß den Figuren 1 bis 4 aufweist. Der Fachmann versteht, dass es sich auch um mehr als zwei Hubsysteme Handeln kann. Die Folientransportrichtung ist durch den Pfeil angedeutet. Eine derartige Anordnung der Hubsysteme eignet sich insbesondere bei sehr großen Formaten, d. h. Formaten mit einem sehr großen Folienvorschub pro Takt. Bei der Anordnung von zwei Hubsystemen hintereinander ist sichergestellt, dass der Druck, mit dem die Werkzeuge gegeneinander gepresst werden, im Wesentlichen über das gesamte Werkzeug zumindest im wesentlichen gleich ist. Durch zwei Zylinder 1 steht die doppelte Anpresskraft zur Verfügung. Die Wellen16 sind parallel zur Folientransportrichtung ausgerichtet und stehen über den Rahmen 5 hinaus. Diese Hubsysteme sind vorzugsweise synchronisiert, besonders bevorzugt zwangssynchronisiert. Dies erfolgt beispielweise durch eine Verbindung mindestens einer Welle 16 des einen Hubsystems mit mindestens einer koaxial zu dieser angeordneten Welle 16 des anderen Hubsystems. Die Verbindung kann eine vorzugsweise wieder lösbare Kupplung sein, die jeweils an den aus dem Rahmen 5 herausstehenden Wellenenden angeordnet wird. Vorzugsweise werden beide Hubsysteme mit einer Regelung gefahren. Weiterhin kann es vorteilhaft sein, wenn auch die Gestelle 3 und/oder die darauf aufliegenden Werkzeugträger, auf denen die Werkzeug aufliegen, miteinander verbunden sind, um ein möglichst gleichmäßiges Anheben und Absenken der Werkzeuge über die gesamte Folienvorschublänge zu erzielen.FIG. 6 shows a workstation which has two lifting systems according to FIGS. 1 to 4. The person skilled in the art understands that it can also be more than two lifting systems. The film transport direction is indicated by the arrow. Such an arrangement of the lifting systems is particularly suitable for very large formats, ie formats with a very large film feed per Clock. In the arrangement of two lifting systems one behind the other, it is ensured that the pressure with which the tools are pressed against one another is at least substantially the same over substantially the entire tool. By two cylinders 1 is the double contact force available. The shafts 16 are aligned parallel to the film transport direction and project beyond the frame 5. These lifting systems are preferably synchronized, particularly preferably forcibly synchronized. This is done, for example, by connecting at least one shaft 16 of a lifting system with at least one shaft 16 of the other lifting system arranged coaxially therewith. The connection may be a preferably releasable coupling, which is arranged in each case on the protruding from the frame 5 shaft ends. Preferably, both lifting systems are driven with a control. Furthermore, it can be advantageous if the racks 3 and / or the tool carriers resting thereon, on which the tools rest, are also connected to one another in order to achieve the most uniform raising and lowering of the tools over the entire film feed length.
Das Hubsystem kann bei allen Ausführungsbeispielen auch wie in der EP 0 569937 oder in der DE 103 51 567.4 ausgebildet sein. The lifting system can also be designed in all exemplary embodiments as in EP 0 569937 or in DE 103 51 567.4.
