Description
Die Erfindung betrifft eine Vorrichtung zum Zuschneiden von Lebensmittelverpackungen entlang einer Längsrichtung. Solche Vorrichtungen können Teil einer Verpackungsmaschine sein und dazu dienen, die nach dem Versiegeln der Verpackungen noch zusammenhängenden Verpackungen in Längsrichtung zuzuschneiden, d.h. in einzelne Verpackungen auseinander zu schneiden. Dieser Vorgang wird auch als "Vereinzeln" bezeichnet.The invention relates to a device for cutting food packaging to size along a longitudinal direction. Such devices can be part of a packaging machine and can be used to cut the packages that are still connected after the packages have been sealed in the longitudinal direction, i.e. to cut them apart into individual packages. This process is also referred to as "separation".
Bislang war es, wenn eine Breite der zuzuschneidenden Lebensmittelverpackungen verändert werden soll, beispielsweise wenn ein anderes Lebensmittelprodukt mit anderen Verpackungsmaßen verarbeitet werden soll, notwendig, eine Schneidwerkzeuge haltende Welle abzubauen, die Schneidwerkzeuge in anderen Abständen zueinander auf der Welle anzuordnen und anschließend die Welle wieder einzubauen.Up to now, if a width of the food packaging to be cut is to be changed, for example if a different food product with different packaging dimensions is to be processed, it has been necessary to dismantle a shaft holding cutting tools, to arrange the cutting tools at different distances from one another on the shaft and then to reinstall the shaft .
Ein solcher Umbau bekannter Vorrichtungen auf eine neue Verpackungsbreite ist mühsam und zeitaufwendig.Such conversion of known devices to a new packaging width is laborious and time-consuming.
Es ist eine Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Zuschneiden von Lebensmittelverpackungen entlang einer Längsrichtung bereitzustellen, mittels der ein schneller und einfacher Umbau von einem Verpackungsmaß auf ein anderes Verpackungsmaß möglich ist. Zudem ist es eine Aufgabe der vorliegenden Erfindung, ein Verfahren bereitzustellen, mittels dem ein schneller und einfacher Umbau von einem Verpackungsmaß auf ein anderes Verpackungsmaß möglich ist.It is an object of the present invention to provide a device for cutting food packaging to size along a longitudinal direction, by means of which a quick and simple conversion from one packaging size to another packaging size is possible. In addition, it is an object of the present invention to provide a method by means of which a quick and simple conversion from one packaging size to another packaging size is possible.
Die Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und insbesondere dadurch, dass die Vorrichtung eine Basis, eine an der Basis angeordnete Tragstruktur und zumindest ein mit der Tragstruktur gekoppeltes Schneidwerkzeug umfasst und das Schneidwerkzeug oder zumindest eines der Schneidwerkzeuge bei an der Basis angeordneter Tragstruktur zwischen einer Schneidstellung und einer Passivstellung verstellbar ist.The object is achieved by a device having the features of claim 1 and in particular in that the device comprises a base, a support structure arranged on the base and at least one cutting tool coupled to the support structure and the cutting tool or at least one of the cutting tools on the base arranged supporting structure between a cutting position and a passive position is adjustable.
Die der Erfindung zugrundeliegende Idee beruht darauf, zumindest eines der Schneidwerkzeuge so an der Tragstruktur, beispielsweise einer Welle, zu befestigen, dass dieses aus einer Schneidstellung heraus verstellt werden kann, ohne das Schneidwerkzeug von der Tragstruktur oder die Tragstruktur von einer Basis, beispielsweise einem Maschinengestell, abnehmen zu müssen. So können aufwendige Umbaumaßnahmen, wie z.B. ein Ausbauen einer Welle, vermieden werden.The idea on which the invention is based is based on fastening at least one of the cutting tools to the supporting structure, for example a shaft, in such a way that it can be moved out of a cutting position without removing the cutting tool from the supporting structure or the supporting structure from a base, for example a machine frame to have to lose weight. In this way, complex conversion measures, such as removing a shaft, can be avoided.
Als Passivstellung wird hierbei eine inaktive Stellung verstanden, d.h. eine Stellung, in der das Schneidwerkzeug zwar weiterhin Teil der Vorrichtung ist, aber nicht zum Schneiden verwendet werden kann.A passive position is understood to mean an inactive position, i.e. a position in which the cutting tool is still part of the device but cannot be used for cutting.
Vorteilhafte Ausführungsformen der Erfindung sind den Unteransprüchen, der Beschreibung und den Zeichnungen zu entnehmen.Advantageous embodiments of the invention can be found in the dependent claims, the description and the drawings.
Gemäß einer Ausführungsform ist die Vorrichtung Teil einer Verpackungsmaschine für Lebensmittelprodukte. Eine solche Verpackungsmaschine weist typischerweise Fördermittel zum Fördern einer Folienbahn auf, welche zumindest einen Teil der erzeugten Verpackung darstellt. Vorzugsweise ist das zumindest eine Schneidwerkzeug der erfindungsgemäßen Vorrichtung in seiner Schneidstellung im Betrieb so angeordnet, dass es mittels der Verpackungsmaschine erzeugte Verpackungen in einer Längsrichtung durchtrennt. Bevorzugt definiert jedes der Schneidwerkzeuge eine Schneidebene, welche parallel zueinander ausgerichtet sind und insbesondere parallel zu einer Förderrichtung der Folienbahn und/oder der Verpackungen ausgerichtet sind.According to one embodiment, the device is part of a packaging machine for food products. Such a packaging machine typically has conveying means for conveying a film web, which represents at least part of the packaging produced. The at least one cutting tool of the device according to the invention is preferably arranged in its cutting position during operation in such a way that it cuts through packaging produced by the packaging machine in a longitudinal direction. Preferably defines each of the Cutting tools have a cutting plane, which are aligned parallel to one another and, in particular, are aligned parallel to a conveying direction of the film web and/or the packaging.
Gemäß einer Ausführungsform ist eine Mehrzahl von in Querrichtung voneinander beabstandet an der Tragstruktur angeordneten Schneidwerkzeugen vorgesehen. Bevorzugt ist eines der Schneidwerkzeuge relativ zu einem anderen der Schneidwerkzeuge, insbesondere zwischen einer Schneidstellung und einer Passivstellung, verstellbar. Vorzugsweise ist das zumindest eine und/oder zumindest ein weiteres der Schneidwerkzeuge relativ zu einem anderen der Schneidwerkzeuge und/oder der Folienbahn verstellbar. Dabei kann das zumindest eine und/oder zumindest ein weiteres der Schneidwerkzeuge relativ zu einem anderen der Schneidwerkzeuge und/oder der Folienbahn zwischen einer Schneidstellung und einer Passivstellung verstellbar sein.According to one embodiment, a plurality of cutting tools arranged at a distance from one another in the transverse direction is provided on the support structure. One of the cutting tools is preferably adjustable relative to another of the cutting tools, in particular between a cutting position and a passive position. The at least one and/or at least one other of the cutting tools can preferably be adjusted relative to another of the cutting tools and/or the film web. In this case, the at least one and/or at least one additional cutting tool can be adjustable relative to another of the cutting tools and/or the film web between a cutting position and a passive position.
Um die Vorrichtung auf möglichst viele verschiedene Verpackungsbreiten einstellen zu können, ist es vorteilhaft, wenn mehrere oder alle Schneidwerkzeuge zwischen einer jeweiligen Schneidstellung und einer jeweiligen Passivstellung verstellbar sind. Durch ein Verstellen der jeweiligen Schneidwerkzeuge können in Querrichtung verschiedene Abstände zwischen sich in jeweiligen Schneidpositionen befindlichen Schneidwerkzeugen erzeugt werden, wodurch sich unterschiedliche Schneidbreitenraster einstellen lassen.In order to be able to adjust the device to as many different packaging widths as possible, it is advantageous if several or all of the cutting tools can be adjusted between a respective cutting position and a respective passive position. By adjusting the respective cutting tools, different distances can be generated in the transverse direction between the cutting tools located in the respective cutting positions, as a result of which different cutting width grids can be set.
Gemäß einer Ausführungsform ist das zumindest eine Schneidwerkzeug in seiner Schneidebene zwischen der Schneidstellung und der Passivstellung verstellbar. In anderen Worten ist das Schneidwerkzeug vorzugsweise derart verstellbar, dass sich die Ausrichtung seiner Schneidebene während des Verstellens nicht ändert.According to one embodiment, the at least one cutting tool can be adjusted in its cutting plane between the cutting position and the passive position. In other words, the cutting tool is preferably adjustable in such a way that the orientation of its cutting plane does not change during the adjustment.
Vorzugsweise ist ein Verstellmechanismus vorgesehen, um das zumindest eine Schneidwerkzeug zwischen der Schneidstellung und der Passivstellung zu verstellen. Der Verstellmechanismus ist vorteilhafterweise derart ausgebildet, dass das Schneidwerkzeug geführt von der Schneidstellung in die Passivstellung und/oder von der Passivstellung in die Schneidstellung bewegbar ist. Gemäß einer Ausführungsform kann jedem Schneidwerkzeug ein separater Verstellmechanismus zugeordnet sein. Alternativ dazu können mehrere Schneidwerkzeuge, d.h. eine Gruppe von Schneidwerkzeugen, einen gemeinsamen Verstellmechanismus aufweisen, sodass die mehreren Schneidwerkzeuge auf einfache Weise zueinander synchron zwischen der Schneidstellung und der Passivstellung verstellbar sind. Hierzu kann die Vorrichtung, speziell der Verstellmechanismus, Kopplungsmittel aufweisen, um die Gruppe von Schneidwerkzeugen derart miteinander zu koppeln, dass die Schneidwerkzeuge gemeinsam von der Schneidstellung in die Passivstellung und/oder von der Passivstellung in die Schneidstellung verstellbar sind.An adjustment mechanism is preferably provided in order to adjust the at least one cutting tool between the cutting position and the passive position. The adjustment mechanism is advantageously designed in such a way that the cutting tool can be moved, guided, from the cutting position into the passive position and/or from the passive position into the cutting position. According to one embodiment, each cutting tool can be assigned a separate adjustment mechanism. As an alternative to this, a plurality of cutting tools, ie a group of cutting tools, can have a common adjustment mechanism, so that the plurality of cutting tools can be adjusted in a simple manner synchronously with one another between the cutting position and the passive position. For this purpose, the device, especially the adjustment mechanism, can have coupling means to couple the group of cutting tools to one another in such a way that the cutting tools can be adjusted together from the cutting position to the passive position and/or from the passive position to the cutting position.
Gemäß einer Ausführungsform ist der Verstellmechanismus dazu ausgebildet, das zumindest eine Schneidwerkzeug um eine Schwenkachse zu verschwenken. Um das zumindest eine Schneidwerkzeug auf besonders einfache Art und Weise zwischen der Schneidstellung und der Passivstellung verstellen zu können, kann der Verstellmechanismus zumindest einen Schwenkarm umfassen. Der Schwenkarm kann mit dem Schneidwerkzeug derart gekoppelt sein, dass sich mittels des Schwenkarms eine Bewegung des Schneidwerkzeugs um die Schwenkachse führen lässt. Vorzugsweise ist das Schneidwerkzeug ortsfest an dem Schwenkarm angeordnet und bewegt sich daher mit einer Schwenkbewegung des Schwenkarms mit. Das Schneidwerkzeug ist aber vorzugsweise drehbar an dem Schwenkarm gelagert.According to one embodiment, the adjustment mechanism is designed to pivot the at least one cutting tool about a pivot axis. In order to be able to adjust the at least one cutting tool between the cutting position and the passive position in a particularly simple manner, the adjustment mechanism can comprise at least one swivel arm. The swivel arm can be coupled to the cutting tool in such a way that the swivel arm can be used to guide a movement of the cutting tool about the swivel axis. The cutting tool is preferably arranged in a stationary manner on the swivel arm and therefore moves with a swiveling movement of the swivel arm. However, the cutting tool is preferably rotatably mounted on the swivel arm.
Gemäß einer Ausführungsform umfasst der Verstellmechanismus einen Verstellantrieb. Der Verstellantrieb kann dazu ausgebildet und eingerichtet sein, einen Schwenkarm des Verstellmechanismus zu verschwenken. Beispielsweise kann der Verstellantrieb einen Hebel betätigen, welcher mit dem Schwenkarm derart gekoppelt ist, dass der Hebel durch seine Bewegung eine Schwenkbewegung des Schwenkarms bedingt. Vorteilhafterweise kann jedem Schneidwerkzeug oder jeder Gruppe von sich synchron bewegenden Schneidwerkzeugen ein separater Verstellantrieb zugeordnet sein. Der Verstellantrieb kann als Pneumatikzylinder ausgebildet sein. Alternativ dazu kann der Verstellantrieb als Elektromotor ausgebildet sein. Vorzugsweise greift eine Verstellkraft des Verstellantriebs an einem distalen Endbereich des Schwenkarms, d.h. an einem der Schwenkachse entgegengesetzten Ende des Schwenkarms, an.According to one embodiment, the adjustment mechanism includes an adjustment drive. The adjustment drive can be designed and set up to pivot a pivot arm of the adjustment mechanism. For example, the adjustment drive can actuate a lever, which is coupled to the swivel arm in such a way that the movement of the lever causes a swiveling movement of the due to the swivel arm. Advantageously, each cutting tool or each group of synchronously moving cutting tools can be assigned a separate adjusting drive. The adjusting drive can be designed as a pneumatic cylinder. As an alternative to this, the adjustment drive can be designed as an electric motor. An adjustment force of the adjustment drive preferably acts on a distal end region of the pivot arm, ie on an end of the pivot arm opposite the pivot axis.
Der zumindest eine Verstellantrieb kann mit einer Steuereinheit der Vorrichtung gekoppelt sein. Die Steuereinheit kann den zumindest einen Verstellantrieb, insbesondere die mehreren Verstellantriebe, steuern, um die Vorrichtung auf verschiedene, beispielsweise hinterlegte, Betriebsstellungen, d.h. Schneidbreitenraster, einzustellen. Die verschiedenen Betriebsstellungen entsprechen in der Regel verschiedenen vorbestimmten Verpackungsbreiten. Beispielsweise kann die Steuereinheit für eine vorbestimmte Verpackungsbreite eine ersten Gruppe Verstellantriebe in eine der Schneidstellung entsprechende Position steuern und eine zweite Gruppe Verstellantriebe in eine der Passivstellung entsprechende Position steuern.The at least one adjustment drive can be coupled to a control unit of the device. The control unit can control the at least one adjustment drive, in particular the multiple adjustment drives, in order to adjust the device to different, for example stored, operating positions, i.e. cutting width grids. The different operating positions usually correspond to different predetermined package widths. For example, for a predetermined packaging width, the control unit can control a first group of adjusting drives into a position corresponding to the cutting position and control a second group of adjusting drives into a position corresponding to the passive position.
Gemäß einer Ausführungsform ist das zumindest eine Schneidwerkzeug als Messer, insbesondere Kreismesser, ausgebildet. Bevorzugt sind alle Schneidwerkzeuge als Messer, insbesondere Kreismesser, ausgebildet. Kreismesser eignen sich besonders gut zum Zuschneiden von Lebensmittelverpackungen entlang einer Längsrichtung.According to one embodiment, the at least one cutting tool is designed as a knife, in particular a circular knife. All cutting tools are preferably designed as knives, in particular circular knives. Circular knives are particularly suitable for cutting food packaging along a longitudinal direction.
Um ein konstant gutes Schneidergebnis zu erhalten, ist es vorteilhaft, wenn ein Gegenmesser oder eine Gegenschneidkante für das Messer vorgesehen ist. Vorzugsweise ist für jedes Messer ein Gegenmesser oder eine Gegenschneidkante vorgesehen. Das Gegenmesser oder die Gegenschneidkante befindet sich im Gebrauch vorzugsweise unterhalb der Folienbahn oder der Folienförderebene. Gemäß einer Ausführungsform ist zumindest ein Gegenmesser oder zumindest eine Gegenschneidkante, insbesondere eines verstellbaren Messers, zwischen einer Schneidstellung oder Aktivstellung und einer Passivstellung verstellbar. Vorzugsweise ist zumindest jedes einem verstellbaren Messer zugeordnete Gegenmesser oder jede einem verstellbaren Messer zugeordnete Gegenschneidkante zwischen einer Schneidstellung oder Aktivstellung und einer Passivstellung verstellbar. Dies hat den Vorteil, dass das Gegenmesser oder das die Gegenschneidkante bildende Element einen Bereich freigeben können, durch den Verpackungen eines neuen Formats befördert werden sollen. Dies ist besonders dann vorteilhaft, wenn sich das Gegenmesser bzw. die Gegenschneidkante im Betrieb über eine Unterseite der Verpackung hinaus in einen Förderbereich der Lebensmittelverpackungen hinein erstreckt, z.B. in einen Bereich zwischen zwei Schalen.In order to obtain a consistently good cutting result, it is advantageous if a counter-knife or a counter-cutting edge is provided for the knife. A counter-knife or a counter-cutting edge is preferably provided for each knife. The counter-knife or the counter-cutting edge is preferably located below the film web or the film conveying plane when in use. According to According to one embodiment, at least one counter-knife or at least one counter-cutting edge, in particular of an adjustable knife, can be adjusted between a cutting position or active position and a passive position. Preferably, at least each counter-knife assigned to an adjustable knife or each counter-cutting edge assigned to an adjustable knife can be adjusted between a cutting position or active position and a passive position. This has the advantage that the counter-knife or the element forming the counter-cutting edge can release an area through which packaging of a new format is to be conveyed. This is particularly advantageous when the counter-knife or the counter-cutting edge extends during operation beyond an underside of the packaging and into a conveying area of the food packaging, for example in an area between two trays.
Gemäß einer Ausführungsform ist eine Abdeckung mit zumindest einer Ausnehmung vorgesehen. Die Abdeckung dient dazu, einen oberen Teil der Vorrichtung, welcher die Schneidwerkzeuge und/oder den Verstellmechanismus umfassen kann, von den Verpackungen räumlich zu trennen. Die zumindest eine Ausnehmung kann so angeordnet sein, dass das Schneidwerkzeug, insbesondere das Messer, in seiner Schneidstellung abschnittsweise durch die Ausnehmung hindurchgreift. In der Passivstellung kann sich das Schneidwerkzeug vollständig auf einer Seite der Abdeckung, insbesondere vollständig über der Abdeckung, befinden.According to one embodiment, a cover with at least one recess is provided. The cover serves to spatially separate an upper part of the device, which can include the cutting tools and/or the adjustment mechanism, from the packaging. The at least one recess can be arranged in such a way that the cutting tool, in particular the knife, reaches through the recess in sections in its cutting position. In the passive position, the cutting tool can be completely on one side of the cover, in particular completely over the cover.
Gemäß einer Ausführungsform ist das zumindest eine Messer auf einer Welle, insbesondere einer rotierbaren Antriebswelle, angeordnet. Vorzugsweise können mehrere Messer oder alle Messer der Vorrichtung auf der Welle, insbesondere der rotierbaren Antriebswelle, angeordnet sein. Das zumindest eine Gegenmesser kann auf einer zweiten Welle, insbesondere einer zweiten rotierbaren Antriebswelle, angeordnet sein. Die erste Welle und die zweite Welle können in entgegengesetzte Richtungen antreibbar sein.According to one embodiment, the at least one knife is arranged on a shaft, in particular a rotatable drive shaft. Preferably, several knives or all knives of the device can be arranged on the shaft, in particular the rotatable drive shaft. The at least one counter knife can be arranged on a second shaft, in particular a second rotatable drive shaft. The first shaft and the second shaft can be drivable in opposite directions.
Gemäß einer Ausführungsform können das Messer und das Gegenmesser eine Rollscherschneideinheit bilden. Dies bedeutet, dass das zumindest eine Messer in Form eines kreisförmigen Messers, d.h. eines Kreismessers, ausgebildet ist und auf einer ersten, in Gebrauchslage vorzugsweise oben liegenden, Welle angeordnet ist. Dem zumindest einen Messer ist zumindest ein kreisförmiges Gegenmesser zugeordnet, das auf einer zweiten, in Gebrauchslage vorzugsweise unterhalb der ersten Welle angeordneten, Welle angeordnet ist. Ein Abstand zwischen einer Mittelachse der ersten Welle und einer Mittelachse der zweiten Welle ist vorzugsweise kleiner als die Summe der Radien eines der Messer und seines entsprechenden Gegenmessers. In anderen Worten liegt das zumindest eine Messer mit seiner Seitenfläche, d.h. Stirnfläche, an seinem entsprechenden Gegenmesser an. Durch ein Drehen der Wellen in entgegengesetzten Richtungen werden die Verpackungen durch einen von den Rollscherschneideinheiten bewirkten Rollscherschnitt voneinander getrennt.According to one embodiment, the knife and the counter-knife can form a rotary shear cutting unit. This means that the at least one knife is designed in the form of a circular knife, i.e. a circular knife, and is arranged on a first shaft, which is preferably on top when in use. At least one circular counter-knife is assigned to the at least one knife, which is arranged on a second shaft, which is preferably arranged below the first shaft in the position of use. A distance between a central axis of the first shaft and a central axis of the second shaft is preferably smaller than the sum of the radii of one of the knives and its corresponding counter knife. In other words, the at least one knife rests with its side surface, i.e. front surface, on its corresponding counter-knife. By rotating the shafts in opposite directions, the packages are separated from each other by a roller shear cut effected by the roller shear cutting units.
Gemäß einer Ausführungsform ist das zumindest eine Messer radial beweglich auf der Welle, insbesondere Antriebswelle, angeordnet. Hierzu kann das Messer über eine Kreuzscheibenkupplung mit der Welle verbunden sein. Vorzugsweise dient die radiale Beweglichkeit des Messers auf der Welle zur Verstellung des zumindest einen Messers zwischen der Schneidstellung und der Passivstellung relativ zu der Welle, welche üblicherweise ortsfest an der Tragstruktur angebracht ist. Das zumindest eine Messer ist vorzugsweise in axialer Richtung auf der Welle fixierbar.According to one embodiment, the at least one knife is arranged so that it can move radially on the shaft, in particular the drive shaft. For this purpose, the blade can be connected to the shaft via a cross-plate clutch. The radial mobility of the blade on the shaft is preferably used to adjust the at least one blade between the cutting position and the passive position relative to the shaft, which is usually fixed in place on the support structure. The at least one blade can preferably be fixed on the shaft in the axial direction.
Gemäß einer Ausführungsform ist das zumindest eine Messer, insbesondere eine Messerschneide des zumindest einen Messers, durch zumindest zwei separate Messerteile gebildet. Vorzugsweise wird die Messerschneide durch zumindest zwei, insbesondere kreisabschnittsförmige, separate Teile gebildet. Vorzugsweise erstrecken sich die kreisabschnittsförmigen Teile über maximal 180°. Dies hat den Vorteil, dass die Messer einfacher auf der Welle fixiert werden und/oder von der Welle entfernt werden können.According to one embodiment, the at least one knife, in particular a knife edge of the at least one knife, is formed by at least two separate knife parts. The knife edge is preferably formed by at least two separate parts, in particular in the shape of a segment of a circle. The parts in the form of a segment of a circle preferably extend over a maximum of 180°. This has the Advantage that the knives can be more easily fixed on the shaft and/or removed from the shaft.
Gemäß einer Ausführungsform ist ein Antrieb zum Erzeugen einer Schneidbewegung des Schneidwerkzeugs vorgesehen. Der Antrieb kann mit der Antriebswelle gekoppelt sein, um die Antriebswelle anzutreiben. Wenn sich das Schneidwerkzeug in der Passivstellung befindet, kann das Schneidwerkzeug weiter angetrieben oder entkoppelt werden. Falls ein Gegenmesser vorgesehen ist, kann der Antrieb zudem mit der zweiten Welle gekoppelt sein, um die Gegenmesser anzutreiben. Alternativ kann ein separater, insbesondere synchronisierter, Antrieb für die zweite Welle vorgesehen sein.According to one embodiment, a drive for generating a cutting movement of the cutting tool is provided. The driver can be coupled to the driveshaft to drive the driveshaft. When the cutting tool is in the passive position, the cutting tool can continue to be driven or decoupled. If a counter-knife is provided, the drive can also be coupled to the second shaft in order to drive the counter-knife. Alternatively, a separate, in particular synchronized, drive can be provided for the second shaft.
Gemäß einer Ausführungsform ist zumindest eines der Schneidwerkzeuge quer, insbesondere senkrecht, zu den Schneidebenen verstellbar. Hierdurch kann die Vorrichtung noch flexibler auf verschiedene Verpackungsbreiten angepasst werden. Sofern mehrere Schneidwerkzeuge vorgesehen sind, können diese einzeln, d.h. relativ zueinander, oder gemeinsam quer zu den Schneidebenen verstellbar sein. Es ist zudem denkbar, dass eine erste Gruppe von Schneidwerkzeugen relativ zu einer zweiten Gruppe von Schneidwerkzeugen quer zu den Schneidebenen verstellbar ist. Der jeweilige Verstellmechanismus und/oder Verstellantrieb kann ebenfalls quer, insbesondere senkrecht, zu den Schneidebenen verstellbar sein.According to one embodiment, at least one of the cutting tools can be adjusted transversely, in particular perpendicularly, to the cutting planes. As a result, the device can be adapted even more flexibly to different packaging widths. If several cutting tools are provided, they can be adjusted individually, i.e. relative to one another, or together transversely to the cutting planes. It is also conceivable that a first group of cutting tools can be adjusted transversely to the cutting planes relative to a second group of cutting tools. The respective adjustment mechanism and/or adjustment drive can also be adjustable transversely, in particular perpendicularly, to the cutting planes.
Die Erfindung betrifft zudem eine Verpackungsmaschine, insbesondere Tiefziehverpackungsmaschine, mit einer erfindungsgemäßen Vorrichtung. Die Verpackungsmaschine kann beispielsweise eine Fördereinrichtung für eine Folienbahn, z.B. in Form zweier in Querrichtung beabstandeter, synchron angetriebener und die Folienbahn seitlich haltender Transportketten, eine Form- und/oder Siegelstation, eine Quertrennstation und eine Etikettierstation umfassen.The invention also relates to a packaging machine, in particular a thermoforming packaging machine, with a device according to the invention. The packaging machine can, for example, comprise a conveying device for a film web, eg in the form of two transversely spaced, synchronously driven transport chains holding the film web laterally, a forming and/or sealing station, a transverse cutting station and a labeling station.
Die Erfindung betrifft zudem ein Verfahren zum Zuschneiden von Verpackungen, insbesondere Lebensmittelverpackungen, entlang einer Längsrichtung mittels einer Vorrichtung, wobei die Vorrichtung eine Basis, eine an der Basis angeordnete Tragstruktur, und zumindest ein mit der Tragstruktur gekoppeltes Schneidwerkzeug umfasst, wobei das Schneidwerkzeug zwischen einer Schneidstellung und einer Passivstellung verstellt wird, um eine Breite der zuzuschneidenden Verpackungen einzustellen, während die Tragstruktur an der Basis angeordnet ist und Zuschneiden der Verpackungen mittels dem zumindest einen sich in seiner Schneidstellung befindlichen Schneidwerkzeug.The invention also relates to a method for cutting packaging, in particular food packaging, along a longitudinal direction using a device, the device comprising a base, a support structure arranged on the base, and at least one cutting tool coupled to the support structure, the cutting tool between a cutting position and a passive position to adjust a width of the packages to be cut while the support structure is positioned on the base and cutting the packages with the at least one cutting tool in its cutting position.
Die Erfindung beruht auf der Idee, eine Breite zu zerschneidender Verpackungen einzustellen, ohne Schneidwerkzeuge von der Vorrichtung abnehmen zu müssen oder Teile der Vorrichtung abbauen zu müssen. Hierdurch kann die Verstellung der Vorrichtung beispielsweise automatisiert erfolgen. Eine Verstellung des zumindest einen Schneidwerkzeugs findet statt, wenn das Verpackungsformat hinsichtlich seiner Breite verändert werden soll, was in der Regel bei Produktwechseln der Fall ist.The invention is based on the idea of setting the width of packaging to be cut without having to remove cutting tools from the device or having to dismantle parts of the device. As a result, the device can be adjusted automatically, for example. The at least one cutting tool is adjusted if the width of the packaging format is to be changed, which is generally the case when there is a product change.
Vorzugsweise ist eine Mehrzahl von in Querrichtung voneinander beabstandet an der Tragstruktur angeordneten Schneidwerkzeugen vorgesehen. Dann kann bei dem Verfahren zumindest eines der Schneidwerkzeuge relativ zu einem anderen der Schneidwerkzeuge verstellt werden. Dabei ist es vorteilhaft, wenn das zumindest eine Schneidwerkzeug relativ zu einem anderen der Schneidwerkzeuge zwischen der Schneidstellung und der Passivstellung verstellt wird, um eine Breite der zuzuschneidenden Verpackungen (21) einzustellen.A plurality of cutting tools arranged at a distance from one another in the transverse direction is preferably provided on the support structure. Then, in the method, at least one of the cutting tools can be adjusted relative to another of the cutting tools. It is advantageous if the at least one cutting tool is adjusted relative to another of the cutting tools between the cutting position and the passive position in order to adjust the width of the packaging (21) to be cut.
Gemäß einer Ausführungsform wird die Vorrichtung auf unterschiedliche Verpackungsbreiten eingestellt, indem ein erster Satz von Schneidwerkzeugen in seine jeweilige Schneidstellung verstellt wird und ein zweiter Satz von Schneidwerkzeugen in seine jeweilige Passivstellung verstellt wird. Wenn die Vorrichtung erneut auf eine andere Verpackungsbreite eingestellt werden muss, kann ein anderer Satz von Schneidwerkzeugen in seine jeweilige Schneidstellung verstellt werden und die restlichen Schneidwerkzeuge in ihre jeweilige Passivstellung verstellt werden. Als Satz von Schneidwerkzeugen wird zumindest ein Schneidwerkzeug, insbesondere eine Mehrzahl von Schneidwerkzeugen, verstanden.According to one embodiment, the device is adjusted to different packaging widths by adjusting a first set of cutting tools to their respective cutting position and a second set of cutting tools to their respective passive position. If the device again has to be adjusted to a different package width, another set of cutting tools can be adjusted to their respective cutting position and the remaining cutting tools can be adjusted to their respective passive position. At least one cutting tool, in particular a plurality of cutting tools, is understood as a set of cutting tools.
Gemäß einer Ausführungsform wird das zumindest eine Schneidwerkzeug in seiner Schneidebene zwischen der Schneidstellung und der Passivstellung verstellt. In anderen Worten kann das Schneidwerkzeug verstellt werden, ohne die Schneidebene des Schneidwerkzeugs zu verändern. Dies hat den Vorteil, dass eine relativ einfache und kostengünstig herzustellende Mechanik zur Verstellung des Schneidwerkzeugs verwendet werden kann.According to one embodiment, the at least one cutting tool is adjusted in its cutting plane between the cutting position and the passive position. In other words, the cutting tool can be adjusted without changing the cutting plane of the cutting tool. This has the advantage that a mechanism that is relatively simple and inexpensive to produce can be used to adjust the cutting tool.
Vorzugsweise wird das zumindest eine Schneidwerkzeug mittels eines Verstellmechanismus zwischen der Schneidstellung und der Passivstellung verstellt. Das zumindest eine Schneidwerkzeug kann mittels des Verstellmechanismus um eine Schwenkachse verschwenkt werden, um das Schneidwerkzeug zwischen der Schneidstellung und der Passivstellung zu verstellen. Hierzu kann ein um die Schwenkachse verschwenkbarer Schwenkarm dienen.The at least one cutting tool is preferably adjusted between the cutting position and the passive position by means of an adjustment mechanism. The at least one cutting tool can be pivoted about a pivot axis by means of the adjustment mechanism in order to adjust the cutting tool between the cutting position and the passive position. A swivel arm that can be swiveled about the swivel axis can be used for this purpose.
Gemäß einer Ausführungsform wird das Schneidwerkzeug, insbesondere rotativ, angetrieben. Das Schneidwerkzeug kann als Messer, insbesondere Kreismesser ausgebildet sein und um eine Mittelachse des Kreismessers angetrieben werden.According to one embodiment, the cutting tool is driven, in particular in a rotary manner. The cutting tool can be designed as a knife, in particular a circular knife, and can be driven about a central axis of the circular knife.
Das zuvor und nachstehend beschriebene Verfahren kann mit einer der beschriebenen Ausführungsformen der Vorrichtung ausgeführt werden. Zudem kann die zuvor und nachstehend beschriebene Vorrichtung dazu ausgebildet sein, einen oder mehrere der beschriebenen Verfahrensschritte durchzuführen.The method described above and below can be carried out with one of the described embodiments of the device.
