Description

Die Erfindung bezieht sich auf eine Verpackungsmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a packaging machine according to the preamble of claim 1.

In vielen Bereichen des Maschinenbaus werden aus Kostengründen aufwendig mechanisch bearbeitete Bauteile durch einfache Blechkonstruktionen ersetzt. Allerdings sind diese kostengünstigeren Blechkonstruktionen im unbearbeiteten Zustand oft nicht in der Lage, die benötigten Maß- bzw. Form- und Lagetoleranzen für die Verwendung in Montagebaugruppen, insbesondere bei beweglichen Baukonstruktionen, zu gewährleisten. Dies führt häufig zum "Verspannen" von statisch überbestimmten Systemen.In many areas of mechanical engineering complex costly mechanical machined components are replaced by simple sheet metal structures. However, these less expensive sheet metal structures in the raw state are often not able to ensure the required dimensional or shape and position tolerances for use in mounting assemblies, especially in mobile structures. This often leads to "distortion" of statically overdetermined systems.

Die EP 3 241 763 A1 offenbart eine Kammerbandmaschine mit einer Siegelvorrichtung für einen Siegelvorgang, wobei die Siegelvorrichtung eine innerhalb des Deckels der Kammerbandmaschine mittels einer aufblasbaren Membran versetzbar gelagerte Siegelschiene aufweist.The EP 3 241 763 A1 discloses a chamber belt machine with a sealing device for a sealing operation, wherein the sealing device comprises a sealing rail displaceably mounted within the lid of the chamber belt machine by means of an inflatable membrane.

Hinsichtlich der eingangs genannten Problematik des "Verspannens" bei der Verwendung einfacher kostengünstiger Blechkonstruktionen innerhalb komplexer, ggf. beweglicher Montagebaugruppen liegt der Erfindung die Aufgabe zugrunde, eine Verpackungsmaschine zur Verfügung zu stellen, bei welcher durch den Einsatz einfacher, technischer Mittel eine Lösung zur Behebung dieser Problematik geschaffen wird.With regard to the above-mentioned problem of "distortion" in the use of simple inexpensive sheet metal structures within complex, possibly movable assembly assemblies, the invention has the object to provide a packaging machine available, in which by the use of simple, technical means a solution to remedy this Problem is created.

Diese Aufgabe wird gelöst durch eine Verpackungsmaschine mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a packaging machine with the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung betrifft eine Verpackungsmaschine, die für einen Arbeitsvorgang mindestens eine relativ zu einem Maschinenrahmen mittels mindestens einer Pneumatikeinheit zwischen einer ersten und einer zweiten Position verstellbar gelagerte Arbeitskomponente aufweist.The invention relates to a packaging machine, which has at least one working component adjustably mounted for at least one relative to a machine frame by means of at least one pneumatic unit between a first and a second position.

Es ist die Idee der Erfindung, dass zumindest teilweise innerhalb eines entlang einer Achse linear verstellbar gelagerten Kolbens der Pneumatikeinheit ein relativ zu der Achse neigbar befestigtes Koppelglied angeordnet ist, über welches die Pneumatikeinheit mit der Arbeitskomponente verbunden ist. Eine Verstellbewegung des Kolbens wird damit mittelbar über das daran neigbar befestigte Koppelglied auf die Arbeitskomponente übertragen, wobei der Kolben und das daran befestigte Koppelglied eine Einheit bilden, die als ein Ausgleichszylinder wirkt, wodurch es möglich ist, die beim Kanten bzw. Schweißen entstandenen Ungenauigkeiten der Montagebaugruppe, insbesondere während eines Verstellens der Arbeitskomponente, auszugleichen (Ausgleichsfunktion).It is the idea of the invention that at least partially disposed within a linearly displaceably mounted on a piston axis of the pneumatic unit is a relative to the axis tiltably mounted coupling member, via which the pneumatic unit is connected to the working component. An adjusting movement of the piston is thus transmitted indirectly via the tiltably attached coupling member to the working component, wherein the piston and the attached coupling member form a unit which acts as a balancing cylinder, whereby it is possible, the resulting in the edges or welding inaccuracies of the mounting assembly, especially during an adjustment of the working component, to compensate (compensation function).

Dadurch, dass gemäß der Erfindung das Koppelglied wenigstens teilweise innerhalb des Kolbens der Pneumatikeinheit integriert aufgenommen ist, bietet die Erfindung eine kompakte Bauweise, bei welcher mittels der Ausgleichszylinderfunktion an der Pneumatikeinheit Winkelfehler, wie auch Ungenauigkeiten entlang verschiedener Raumrichtungen, im zusammengebauten Zustand der Montagebaugruppe kompensierbar sind.Characterized in that according to the invention, the coupling member is at least partially integrated within the piston of the pneumatic unit, the invention provides a compact design in which by means of the compensating cylinder function on the pneumatic unit angle errors, as well as inaccuracies along different spatial directions, in the assembled state of the mounting assembly can be compensated ,

Ein weiterer großer Vorteil der bei der Erfindung eingesetzten Pneumatikeinheit mit Ausgleichsfunktion besteht darin, dass es selbst bei einer nicht synchronisierten Verfahrbewegung mehrerer mit der Arbeitskomponente erfindungsgemäß verbundener Pneumatikeinheiten nicht zum Verspannen bzw. Klemmen der Bauteile kommt, weil die jeweiligen Pneumatikeinheiten untereinander gewisse Montageungenauigkeiten gut kompensieren können. Dadurch wird eine einwandfreie Funktion der Arbeitskomponente, beispielsweise einer Siegeleinheit mit Siegelschiene, gewährleistet.Another major advantage of the pneumatic unit with compensation function used in the invention is that it does not cause distortion or jamming of the components even with a non-synchronized movement of several with the working component connected pneumatic units, because the respective pneumatic units can compensate each other certain assembly inaccuracies well , This ensures proper functioning of the working component, for example a sealing unit with a sealing rail.

Gemäß einer Variante ist das Koppelglied als ein ausgedehnter, ggf. mehrteiliger, starrer Körper ausgebildet, wobei es an seinen jeweiligen Enden zwischen der Pneumatikeinheit und der Arbeitskomponente beweglich aufgehängt ist. Vorzugsweise ist das Koppelglied während des Betriebs in einer Gleichgewichtslage ausgerichtet, in welcher es vertikal angeordnet ist. Sofern das Koppelglied während des Betriebs zum Erreichen des oben beschriebenen Ausgleichseffekts aus seiner Gleichgewichtslage heraus gelenkt wird, kann es innerhalb eines Arbeitstaktes selbsttätig durch eine auf das Koppelglied wirkende Rückstellkraft wieder in seine Gleichgewichtslage zurückschwenken.According to a variant, the coupling member is formed as an extended, possibly multi-part, rigid body, wherein it is suspended at its respective ends between the pneumatic unit and the working component movable. Preferably, the coupling member is aligned during operation in an equilibrium position in which it is arranged vertically. If the coupling member is deflected out of its equilibrium position during operation to achieve the balancing effect described above, it can automatically swing back into its equilibrium position within a power stroke by acting on the coupling member restoring force.

Im abstrakten Sinne kann das Koppelglied zwischen dem linear verschiebbar angeordneten Kolben der Pneumatikeinheit und der damit bewegten Arbeitskomponente wie ein physikalisches Pendel gekoppelt sein, wodurch es möglich ist, die mittels des Kolbens durchgeführte lineare Hubbewegung mit einer um einen Auslenkwinkel behafteten Bewegungskomponente, d.h. entsprechend der Auslenkung des Koppelglieds aus dessen Gleichgewichtslage heraus, zu ergänzen, um anhand dieser überlagerten Bewegung ein Verspannen der aneinander gekoppelten Bauteile zu vermeiden.In the abstract sense, the coupling member may be coupled between the linearly displaceable piston of the pneumatic unit and the working component moved therewith, such as a physical pendulum, whereby it is possible to perform the linear lifting movement performed by the piston with a motion component affected by a deflection angle, i. in accordance with the deflection of the coupling member out of its equilibrium position, to supplement in order to avoid distortion of the mutually coupled components based on this superimposed movement.

Vorzugsweise ist das Koppelglied innerhalb des Kolbens dreiachsig rotierbar zur Achse gelagert. Es ist damit bezüglich der (Kolben-)Achse in alle Richtungen schwenkbar befestigt, sodass hinsichtlich ggf. vorliegender Montageungenauigkeiten eine maximale Ausgleichsfunktion vorliegt. Die Verbindung des Kolbens mit der Arbeitskomponente über das bewegliche Koppelglied ermöglicht ein ausreichendes Spiel, um zuverlässig ein Verspannen bzw. Verklemmen zwischen dem linear geführten Kolben und der damit bewegten, allerdings nicht starr mit dem Kolben verbundenen Arbeitskomponente zu verhindern. Hinzu kommt, dass das damit in allen Richtungen gelenkig gelagerte Koppelglied besonders bei wiederkehrenden Arbeitsvorgängen, insbesondere zur Vermeidung von Materialermüdungserscheinungen, vorteilhaft einsetzbar ist, damit die Verpackungsmaschine auf lange Sicht einwandfrei arbeiten kann.Preferably, the coupling member is mounted within the piston rotatable three axes to the axis. It is thus pivotally mounted in all directions with respect to the (piston) axis, so that there is a maximum compensation function with regard to possibly existing assembly inaccuracies. The connection of the piston with the working component via the movable coupling member allows sufficient clearance to reliably prevent jamming between the linearly guided piston and the moving component but not rigidly connected thereto to the piston. In addition, the coupling member so articulated in all directions can be used advantageously, especially in the case of recurring work processes, in particular to avoid material fatigue phenomena, so that the packaging machine can work flawlessly in the long term.

Vorteilhaft ist es, wenn der Kolben eine zumindest teilweise hohl ausgebildete Kolbenstange aufweist, innerhalb welcher das Koppelglied gelenkig befestigt ist. Ein solcher Kolben bildet zusammen mit dem zumindest teilweise darin aufgenommenen Koppelglied eine kompakte Ausgleichszylindereinheit und ist gleichzeitig einfach herstellbar.It is advantageous if the piston has an at least partially hollow piston rod, within which the coupling member is articulated. Such a piston forms together with the at least partially received therein coupling member a compact compensation cylinder unit and at the same time easy to manufacture.

Vorzugsweise weist das Koppelglied an einem ersten Ende ein erstes Gelenk, womit es innerhalb des Kolbens gelenkig befestigt ist, und/oder an einem zweiten Ende ein zweites Gelenk auf, womit es gelenkig mit der Arbeitskomponente verbunden ist. Dadurch kann gezielt zwischen der Pneumatikeinheit und der mittels dieser verstellbar gelagerten Arbeitskomponente ein mechanisches Spiel geschaffen werden, das vorteilhaft zur Vermeidung statischer Verspannungen zwischen den gekoppelten Bauteilen eine Ausgleichsfunktion herstellt, selbst wenn es über längere Zeit zu zahlreichen Wiederholungen des mittels der Arbeitskomponente durchgeführten Arbeitsprozesses kommt.Preferably, the coupling member at a first end of a first joint, whereby it is hinged within the piston, and / or at a second end to a second joint, whereby it is pivotally connected to the working component. As a result, it is possible to create a mechanical clearance between the pneumatic unit and the working component which is adjustably mounted by means of this component, which advantageously produces a compensation function to avoid static tension between the coupled components, even if there are numerous repetitions of the working process carried out by the working component over a longer period of time.

Gemäß einer verbesserten Variante ist vorgesehen, dass das erste und das zweite Gelenk jeweils ein Schwenk- oder ein Kugelgelenk sind. Diese Gelenke bilden eine einfach und kostengünstig realisierbare Lösung, die sich konstruktiv hervorragend für die Ausgleichsfunktion zwischen der Pneumatikeinheit und der daran befestigten Arbeitskomponente eignen.According to an improved variant, it is provided that the first and the second joint are each a pivot or a ball joint. These joints form a simple and cost-effective solution, which are structurally excellent for the compensation function between the pneumatic unit and the attached working component.

Vorzugweise ist das Koppelglied innerhalb des Kolbens mittels eines senkrecht zur Achse gelagerten Bolzens am Kolben neigbar befestigt. Eine vergleichbare Befestigung kann auch zwischen dem Koppelglied und der damit verbundenen Arbeitskomponente vorliegen. Vorzugsweise ist das Koppelglied zur Erfüllung einer Austausch- und/oder Umbaufunktion lösbar innerhalb des Kolbens befestigt.Preferably, the coupling member is pivotally mounted within the piston by means of a pin mounted perpendicular to the axis of the piston. A comparable attachment may also be present between the coupling member and the associated working component. Preferably, the coupling member is releasably secured within the piston to perform an exchange and / or conversion function.

Eine Ausführungsvariante sieht vor, dass das Koppelglied einen daran austauschbar befestigten Verbinderstift umfasst, um eine vorbestimmte Längserstreckung des Koppelglieds zu erhalten. Es können hierbei jeweils unterschiedlich lange Verbinderstifte am Koppelglied zum Einsatz kommen, um das Koppelglied als solches unterschiedlich lang für einen bestimmten Zweck auszubilden, beispielsweise um an verschiedenen Verpackungsmaschinentypen und/oder mit verschiedenen Arbeitskomponenten verwendet zu werden. Insbesondere lässt sich dadurch eine variierbare Siegeleinstellhöhe einstellen, sodass mittels der Verpackungsmaschine ein Herstellen unterschiedlicher Produktchargen mit verschiedenen Produktgrößen möglich ist.A variant embodiment provides that the coupling member comprises a connector pin fastened thereto exchangeable, in order to obtain a predetermined longitudinal extent of the coupling member. In each case, connector pins of different lengths may be used on the coupling element in order to design the coupling element as such of different lengths for a specific purpose, for example, to be used on different types of packaging machines and / or with different working components. In particular, this allows a variable Siegeleinstellhöhe set so that by means of the packaging machine producing different product batches with different product sizes is possible.

Eine vorteilhafte Variante sieht vor, dass eine Hubbewegung an der Arbeitskomponente mittels mehrerer mit ihr verbundenen Pneumatikeinheiten durchführbar ist und/oder die Arbeitskomponente entlang einer Führung verschiebbar gelagert ist. Der im Bereich der Pneumatikeinheit(en) zweckmäßig mit einem mechanischen Spiel versehene Antrieb zum Ausgleich von Montageungenauigkeiten kann damit sinnvoll mittels der Führung kompensiert werden, um die Pneumatik-Antriebsbewegung präzise dergestalt auf die Arbeitskomponente zu übertragen, dass sie positionsgenau aus der ersten in die zweite Position überführt werden kann, in welcher ein mittels der Arbeitskomponente durchgeführter Arbeitsvorgang, beispielsweise ein Siegel-, Abdicht- und/oder Schneidvorgang stattfindet. So betrachtet kann der bei der Erfindung zweckgemäß zum Ausgleich von Lage- und Montageungenauigkeiten versehene Pneumatikantrieb in Zusammenspiel mit der Führung sicherstellen, dass die Arbeitskomponente ohne zu verkanten präzise in ihre Arbeitsposition bewegt werden kann.An advantageous variant provides that a lifting movement can be performed on the working component by means of a plurality of pneumatic units connected to it and / or the working component is displaceably mounted along a guide. The provided in the pneumatic unit (s) expediently with a mechanical clearance drive to compensate for assembly inaccuracies can thus be sensibly compensated by means of the guide to precisely transfer the pneumatic drive movement dergestalt on the working component, that they position accurate from the first to the second Position can be transferred, in which a carried out by means of the working component operation, such as a sealing, sealing and / or cutting process takes place. From this point of view, the pneumatic drive provided in accordance with the invention to compensate for positional and assembly inaccuracies, in cooperation with the guide, can ensure that the working component can be moved precisely into its working position without jamming.

Vorzugsweise sind die mehreren Pneumatikeinheiten nebeneinander, insbesondere in einer Reihe, an der Verpackungsmaschine angeordnet, damit die jeweiligen Pneumatikeinheiten versetzt an unterschiedlichen Stellen entlang der Arbeitskomponente ansetzen, um diese im Betrieb zwischen den jeweiligen Arbeitspositionen zu verlagern.Preferably, the plurality of pneumatic units are arranged side by side, in particular in a row, on the packaging machine, so that the respective pneumatic units staggered at different locations along the working component, in order to shift them in operation between the respective working positions.

Vorzugsweise umfasst die Verpackungsmaschine eine Siegelstation und die Arbeitskomponente ist als eine daran verstellbar befestigte Siegelschiene ausgebildet. Speziell für die Anwendung an der Siegelstation ist die erfindungsgemäße Pneumatikeinheit mit Ausgleichsfunktion hervorragend geeignet, um die daran gekoppelte Siegelschiene gemäß einem Maschinentakt der Verpackungsmaschine immer wieder aufs Neue zwischen den jeweiligen Positionen spannungsfrei zu verlagern. Vorstellbar wäre es allerdings auch, dass die erfindungsgemäß ausgebildete Pneumatikeinheit bzw. mehrere davon zur Bewegung einer an einer Formstation, Einlegestation, Begasungsstation und/oder Schneidstation bewegbar gelagerten Arbeitskomponente zum Einsatz kommt.Preferably, the packaging machine comprises a sealing station and the working component is designed as a seal rail fastened thereto in an adjustable manner. Specially for use at the sealing station, the pneumatic unit according to the invention with compensation function is excellently suited to relocate the sealed thereto sealing rail according to a machine cycle of the packaging machine again and again between the respective positions stress-free. However, it would also be conceivable for the pneumatic unit or several of them designed according to the invention to be used for moving a working component movably mounted on a forming station, infeed station, gassing station and / or cutting station.

Vorteilhaft ist es, wenn die Pneumatikeinheit auf einem Deckel der Siegelstation angeordnet ist, wobei das Koppelglied der Pneumatikeinheit mit der innerhalb des Deckels positionierten Siegelschiene verbunden ist. Die auf dem Deckel der Siegelstation vorgesehene Positionierung der Pneumatikeinheit gibt innerhalb des Deckels Platz frei, um andere Arbeitsmodule vorzusehen.It is advantageous if the pneumatic unit is arranged on a lid of the sealing station, wherein the coupling member of the pneumatic unit is connected to the sealing rail positioned within the lid. The positioning of the pneumatic unit provided on the lid of the sealing station releases space within the lid to provide other working modules.

Hinzu kommt, dass die auf dem Deckel, d.h. nicht innerhalb des Deckels, positionierte Pneumatikeinheit hervorragend mit Druckluft versorgt werden kann und ferner besser für Service- und/oder Reinigungsprozesse erreichbar ist.In addition, on the lid, i. not within the lid, positioned pneumatic unit can be supplied with excellent air pressure and also better accessible for service and / or cleaning processes.

Vorzugsweise weist die Verpackungsmaschine mindestens vier Pneumatikeinheiten auf. Diese lassen sich besonders wirksam für einen gekoppelten pneumatischen Betrieb ansteuern und können die Arbeitskomponente, beispielsweise eine länglich ausgebildete und mit den jeweiligen Pneumatikeinheiten gekoppelte Siegelschiene, spannungsfrei sowie mit einer vorbestimmten Kraft und Geschwindigkeit in die Arbeitsposition versetzen und in dieser gedrückt halten.Preferably, the packaging machine has at least four pneumatic units. These can be particularly effective control for a coupled pneumatic operation and can put the working component, such as a longitudinally trained and coupled to the respective pneumatic units seal bar, stress-free and with a predetermined force and speed in the working position and hold in this.

Das erfinderische Prinzip hat sich insbesondere vorteilhaft an einer Verpackungsmaschine erwiesen, die eine Kammerbandmaschine ist. Vorzugsweise handelt es sich um eine Kammerbandmaschine, deren Siegelstation mit zwei Siegelschienen ausgerüstet ist und eine beidseitige Beladung ermöglicht.The inventive principle has proven particularly advantageous on a packaging machine, which is a chamber belt machine. Preferably, it is a chamber belt machine whose sealing station is equipped with two sealing rails and allows loading on both sides.

Figur 1 zeigt eine Verpackungsmaschine 1, die in Form einer Kammerbandmaschine 2 ausgebildet ist. Die Kammerbandmaschine 2 umfasst eine Siegelstation 3 für einen Siegelvorgang S und eine Transportvorrichtung 4 für einen Beladeprozess der Siegelstation 3. Die in Figur 1 gezeigte Kammerbandmaschine 2 ist für einen beidseitigen Beladeprozess ausgebildet. In Transportrichtung P betrachtet, werden auf einem Förderband 5 der Transportvorrichtung 4 Produkte 6 der Siegelstation 2 für einen Arbeitsvorgang A, insbesondere einen Siegelvorgang S, zugeführt. FIG. 1 shows a packaging machine 1, which is designed in the form of a chamber belt machine 2. The chamber belt machine 2 comprises a sealing station 3 for a sealing process S and a transport device 4 for a loading process of the sealing station 3. Die in FIG. 1 shown chamber belt machine 2 is designed for a two-sided loading process. Viewed in the transport direction P, products 6 of the sealing station 2 for a work A, in particular a sealing process S, are fed onto a conveyor belt 5 of the transport device 4.

In Figur 1 besitzt die Siegelstation 3 einen Deckel 7, der mittels eines Antriebs 8 relativ zu einem Maschinenrahmen 10 der Verpackungsmaschine 1 vertikal höhenverstellbar gelagert ist. Auf dem Deckel 7 sind in einer ersten Reihe R1 und in einer zweiten Reihe R2, jeweils in Produktionsrichtung P aneinandergereiht fünf Pneumatikeinheiten 9 positioniert. Die jeweiligen in Fünfergruppen angeordneten Pneumatikeinheiten 9 sind dazu ausgebildet, jeweilige innerhalb des Deckels 7 angeordnete Arbeitskomponenten 14, insbesondere beidseitig innerhalb des Deckels 7 positionierte Siegelschienen 15 (siehe Figur 2), zu bewegen.In FIG. 1 the sealing station 3 has a lid 7, which is mounted vertically vertically adjustable by means of a drive 8 relative to a machine frame 10 of the packaging machine 1. On the cover 7 five pneumatic units 9 are positioned in a first row R1 and in a second row R2, in each case in the production direction P strung together. The respective arranged in groups of five pneumatic units 9 are adapted to respective arranged within the lid 7 working components 14, in particular both sides within the lid 7 positioned sealing rails 15 (see FIG. 2 ), to move.

Figur 2 zeigt in perspektivischer Schnittdarstellung entlang dem Schnitt Q-Q gemäß Figur 1 zwei Pneumatikeinheiten 9 mit Ausgleichsfunktion. Das erfinderische Prinzip wird im Folgenden anhand einer der auf dem Deckel 7 befestigten Pneumatikeinheiten 9 beschrieben. FIG. 2 shows in a perspective sectional view along the section QQ according to FIG. 1 two pneumatic units 9 with compensation function. The inventive principle is described below with reference to one of the fastened on the cover 7 pneumatic units 9.

Für die Ausgleichsfunktion weist die Pneumatikeinheit 9 einen Kolben 11 auf, der innerhalb der Pneumatikeinheit 9 entlang einer Achse 12 linear verstellbar gelagert ist. Der Kolben 11 ist derart hohl ausgebildet, dass in ihm zumindest teilweise ein Koppelglied 13 aufgenommen ist, das relativ zu der Achse 12 neigbar gelagert ist. Über das Koppelglied 13 ist die Pneumatikeinheit 9 mit einer im Deckel 7 der Siegelstation 3 angeordneten Arbeitskomponente 14 verbunden.For the compensation function, the pneumatic unit 9 has a piston 11, which is mounted within the pneumatic unit 9 along an axis 12 linearly adjustable. The piston 11 is hollow in such a way that it at least partially a coupling member 13 is received in it, which is mounted relative to the axis 12 tiltably. Via the coupling member 13, the pneumatic unit 9 is connected to a arranged in the lid 7 of the sealing station 3 working component 14.

Gemäß Figur 2 ist die Arbeitskomponente 14 innerhalb der Siegelstation 3 als Siegelschiene 15 ausgebildet. Die Siegelschiene 15 bildet ein Werkzeug zum Verschließen der der Siegelstation 3 zugeführten Produkte 6. Die Siegelschiene 15 ist anhand einer Hubbewegung 17 mittels der Pneumatikeinheit 9 zwischen einer ersten Position P1 und einer zweiten Position P2 verstellbar gelagert. In der ersten Position P1 ist sie innerhalb des Deckels 7 nach oben angehoben positioniert. In der zweiten Position P2 ist die Siegelschiene 15 in einer Siegellage positioniert, in welcher sie die der Siegelstation 3 zugeführten Produkte 6 in einer vorbestimmten Siegelhöhe versiegelt.According to FIG. 2 the working component 14 is formed within the sealing station 3 as a sealing rail 15. The sealing rail 15 forms a tool for closing the sealing station 3 supplied products 6. The sealing rail 15 is mounted by means of a lifting movement 17 by means of the pneumatic unit 9 between a first position P1 and a second position P2 adjustably. In the first position P1, it is positioned raised within the lid 7. In the second position P2, the sealing rail 15 is positioned in a sealed position, in which it seals the products 6 supplied to the sealing station 3 at a predetermined sealing height.

Weiter zeigt Figur 2, dass die Pneumatikeinheit 9 einen Druckluftanschluss 18 aufweist, über den zur linearen Verstellung des Kolbens 11 Druckluft ins Innere der Pneumatikeinheit 9 gefördert wird, um den Kolben 11 nach unten zu drücken. Die Siegelschiene 15 kann dadurch über die Kolbenbewegung und das zwischen dem Kolben 11 und ihr befestigte Koppelglied 13 in die Siegellage versetzt werden.Next shows FIG. 2 in that the pneumatic unit 9 has a compressed air connection 18, via which compressed air for the linear displacement of the piston 11 is conveyed into the interior of the pneumatic unit 9 in order to press the piston 11 downwards. The sealing rail 15 can be offset by the piston movement and the attached between the piston 11 and its coupling member 13 in the sealing position.

Mittels einer innerhalb der Pneumatikeinheit 9 am Umfang des Kolbens 11 angeordneten Feder 19 wirkt auf den mittels Druckluft nach unten gedrückten Kolben 11 eine Rückstellkraft F, um den Kolben 11 in seine obere Ausgangslage zurück zu bringen, in welcher die Siegelschiene 15 in der ersten Position P1 angeordnet ist. Ferner zeigt Figur 2, dass die Siegelschiene 15 entlang einer Führung 16 zwischen der ersten Position P1 und der zweiten Position P2 verstellbar gelagert ist.By means disposed within the pneumatic unit 9 on the circumference of the piston 11 spring 19 acts on the means of compressed air downwardly compressed piston 11, a restoring force F to bring the piston 11 in its upper initial position, in which the sealing rail 15 in the first position P1 is arranged. Further shows FIG. 2 in that the sealing rail 15 runs along a guide 16 is adjustably mounted between the first position P1 and the second position P2.

Die im Zusammenhang mit der Pneumatikeinheit 9 gemäß Figur 2 beschriebenen Merkmale treffen auch auf die anderen auf dem Deckel 7 angeordneten Pneumatikeinheiten 9 zu.The in connection with the pneumatic unit 9 according to FIG. 2 described features also apply to the other arranged on the cover 7 pneumatic units 9.

Figur 3 zeigt die an der erfindungsgemäßen Verpackungsmaschine 1, insbesondere die an der gemäß Figur 1 gezeigten Kammerbandmaschine 2, eingesetzte Pneumatikeinheit 9 in Schnittdarstellung vergrößert. FIG. 3 shows the on the packaging machine 1 according to the invention, in particular those according to the FIG. 1 shown chamber belt machine 2, pneumatic unit 9 used enlarged in a sectional view.

In Figur 3 ist die Verbindung zwischen der Pneumatikeinheit 9 und der Siegelschiene 15 ohne den Deckel 7 der Siegelstation 3 dargestellt. Figur 3 zeigt, dass der Kolben 11 eine hohl ausgebildete Kolbenstange 20 aufweist. Das Koppelglied 13 ist beinahe komplett innerhalb der hohl ausgebildeten Kolbenstange 20 aufgenommen.In FIG. 3 the connection between the pneumatic unit 9 and the sealing rail 15 without the cover 7 of the sealing station 3 is shown. FIG. 3 shows that the piston 11 has a hollow piston rod 20 formed. The coupling member 13 is almost completely received within the hollow piston rod 20.

Figur 3 zeigt auch, dass der Kolben 11 der Pneumatikeinheit 9 mit seinem unteren Ende 21 auf einer an der Arbeitskomponente 14 ausgebildeten Oberfläche 22 aufsitzt, daran allerdings nicht starr befestigt ist. Das untere Ende 21 des Kolbens 11 kann daher, sofern das Koppelglied 13 um einen in Figur 3 beispielhaft dargestellten Auslenkwinkel α aus dessen vertikalen Gleichgewichtslage G herausgelenkt wird, entlang der Oberfläche 22 ausweichen, damit es zu keinem Verspannen zwischen dem Kolben 11 und der Siegelschiene 15 kommt. FIG. 3 also shows that the piston 11 of the pneumatic unit 9 is seated with its lower end 21 on a formed on the working component 14 surface 22, but it is not rigidly attached. The lower end 21 of the piston 11 can therefore, provided the coupling member 13 to a in FIG. 3 shown deflection angle α is deflected out of the vertical equilibrium position G, dodge along the surface 22, so there is no distortion between the piston 11 and the sealing rail 15.

Das Koppelglied 13 ragt über den Kontaktbereich zwischen dem unteren Ende 21 des Kolbens 11 und der Oberfläche 22 hinaus in eine an der Siegelschiene 15 ausgebildete Aufnahme 23 hinein, in welcher es beweglich befestigt ist. Figur 3 zeigt auch, dass ein erstes Ende 24 des Koppelglieds 13 innerhalb der hohl ausgebildeten Kolbenstange 20 mittels eines ersten Bolzens 25 und ein zweites Ende 26 des Koppelglieds 13 innerhalb der Aufnahme 24 der Siegelschiene 15 mittels eines zweiten Bolzens 27 beweglich befestigt sind.The coupling member 13 protrudes beyond the contact area between the lower end 21 of the piston 11 and the surface 22 into a receptacle 23 formed on the sealing rail 15 in which it is movably mounted. FIG. 3 also shows that a first end 24 of the coupling member 13 within the hollow piston rod 20 by means of a first pin 25 and a second end 26 of the coupling member 13 are movably mounted within the receptacle 24 of the sealing rail 15 by means of a second pin 27.

Das erste Ende 24 des Koppelglieds 13 umfasst ein erstes Gelenk 28, womit es innerhalb des Kolbens 11 gelenkig befestigt ist. Das zweite Ende 26 des Koppelglieds 13 umfasst ein zweites Gelenk 29, womit das Koppelglied 13 gelenkig mit der Siegelschiene 15 innerhalb dessen Aufnahme 23 befestigt ist.The first end 24 of the coupling member 13 includes a first hinge 28, whereby it is articulated within the piston 11. The second end 26 of the coupling member 13 includes a second hinge 29, whereby the coupling member 13 is hinged to the sealing rail 15 within its receptacle 23.

Gemäß Figur 3 besitzt das Koppelglied 13 zwischen dem ersten Ende 24 und dem zweiten Ende 26 einen Verbinderstift 30, um eine vorbestimmte Längserstreckung L des Koppelglieds 13 zu erhalten. Der Verbinderstift 30 ist an seinen jeweiligen Enden mit einem Gewinde ausgebildet, woran die jeweiligen Enden 24, 26 des Koppelglieds 13 angeschraubt befestigt sind. Der Verbinderstift 30 kann hinsichtlich einer vorbestimmten Siegelhöhe unterschiedlich lang ausgebildet sein.According to FIG. 3 The coupling member 13 between the first end 24 and the second end 26 has a connector pin 30 to obtain a predetermined longitudinal extent L of the coupling member 13. The connector pin 30 is formed at its respective ends with a thread, to which the respective ends 24, 26 of the coupling member 13 are attached screwed. Of the Connector pin 30 may be formed differently in length with respect to a predetermined seal height.

Figur 4 zeigt das Koppelglied 13 in isolierter Darstellung. Das erste Gelenk 28 umfasst ein erstes Kugelgelenk 31 und das zweite Gelenk 29 ein zweites Kugelgelenk 32. Die jeweiligen Kugelgelenke 31, 32 gestatten es, dass das Koppelglied 13 innerhalb des Kolbens 11 dreiachsig um dessen Aufhängungspunkt 40 (siehe Figur 3) rotierbar relativ zur Achse 12 gelagert ist. Der an der Pneumatikeinheit 9 linear geführte Kolben 11 lässt sich damit über das Koppelglied 13 derart mit der Arbeitskomponente 14, d.h. der Siegelschiene 15, verbinden, dass während der Hubbewegung 17 keine statischen Verspannungen bzw. ein Verkanten zwischen der Pneumatikeinheit 9 und der Arbeitskomponente 14 auftreten. FIG. 4 shows the coupling member 13 in an isolated view. The first joint 28 includes a first ball joint 31 and the second joint 29 a second ball joint 32. The respective ball joints 31, 32 allow the coupling member 13 within the piston 11 in three axes around its suspension point 40 (see FIG. 3 ) rotatably mounted relative to the axis 12. The linearly guided on the pneumatic unit 9 piston 11 can thus on the coupling member 13 in such a way with the working component 14, ie the sealing rail 15, connect that occur during the lifting movement 17 no static tension or tilting between the pneumatic unit 9 and the working component 14 ,

Das erfindungsgemäße Prinzip wurde anhand einer an der Pneumatikeinheit 9 befestigten in Form einer Siegelschiene 15 ausgebildeten Arbeitskomponente 14 beschrieben. Nichtsdestotrotz lässt sich das erfindungsgemäße Prinzip auch an anderen verstellbar gelagerten Arbeitskomponenten anwenden. Vorstellbar wäre es beispielsweise auch, eine verstellbar gelagerte Schneideinrichtung anhand des erfindungsgemäßen Prinzips verstellbar zu lagern.The principle according to the invention has been described on the basis of a working component 14 which is fastened to the pneumatic unit 9 and which is in the form of a sealing rail 15. Nevertheless, the principle according to the invention can also be applied to other adjustably mounted working components. It would also be conceivable, for example, to adjustably store an adjustably mounted cutting device on the basis of the principle according to the invention.
