Definitions
- the present invention relates to a packaging machine, in particular a tray sealing machine, with a cutting tool.
- Sealed packagings in particular plastic packagings, are used for as far as possible all product types. Frequently, fresh food products are inserted or portioned in a deep-drawn plastic dish and then the shell with a plastic film by means of a heat-sealing seam, weld or adhesive seam hermetically sealed.
- the sealing tool used for this purpose in particular the sealing plate, is usually heated for this purpose and presses the plastic film onto the edges of the shell in order to connect the two together.
- the plastic film can also be deep drawn to form a vacuum and so put over the product. Particularly suitable for this type of seal are so-called “skin foils", which are particularly flexible and fit closely over the product in the shell.
- the film Since the film is usually supplied continuously from a roll, the film must be cut at the edges of the shell after the sealing process.
- the sealing tool and the cutting tool in today's conventional packaging machines are not distributed to two stations along a conveyor line, but mechanically interconnected as components of a packaging station.
- a corresponding method for gas-tight packaging of a product by means of such a packaging station is known.
- the object of the invention is to provide a packaging machine with a sealing tool and an improved cutting tool.
- a packaging machine according to the invention in particular a tray sealing machine, comprises a sealing station which has a sealing tool with a tray receptacle and a sealing plate for the gas-tight sealing of a tray with a film material and a cutting tool for cutting the film material.
- the packaging machine comprises at least one induction coil winding and the cutting tool comprises a cutting blade, wherein the at least one induction coil winding is configured to inductively heat the cutting blade.
- the principle of magnetic induction transmits the electrical energy of the voltage applied to the induction coil winding non-contact by a changing magnetic field on a spatially adjacent, but electrically isolated from the induction coil winding material, in this case the cutting blade of the cutting tool.
- eddy currents are induced by the magnetic field generated by the induction coil winding, which lead to a heating of the cutting blade due to the electrical resistance of the material.
- the heating of a material by means of magnetic induction is a much more energy-efficient process than, for example, the transmission of thermal energy from a resistance-heated coil winding.
- the cutting blade can be brought to a desired temperature and the temperature permanently maintained.
- the cutting blade can thus be kept independent of a heating of the sealing plate on a favorable for cutting the film temperature. This results in an improved and consistently high-quality cut.
- the required cutting force is reduced, which is advantageous for the mechanics used and reduces the wear of the cutting blade.
- the cutting tool can be adjusted so that either only the film or the film and a horizontal edge of the shell are cut shaping.
- the shell lies with its horizontal edge on the shell receptacle, whereby the necessary mechanical counterforce is given.
- the at least one induction coil winding in the sealing plate and / or in the shell receptacle and / or in a sealing plate receiving the outer frame of the sealing station is arranged.
- the induction coil winding should be arranged without direct contact with the cutting blade, but spatially adjacent to it.
- the induction coil winding can, for. B. be arranged with its cross-section parallel to the surface of the cutting blade in a recess of the sealing plate and / or the outer frame of the sealing station and thus heat the cutting blade mainly in its upper rest position.
- the induction coil winding can be arranged in the shell receptacle.
- Heating of the cutting blade in this case takes place during the approach and contact of the cutting blade with the tray receptacle or the horizontal edge of the tray for cutting the film material. It is understood that induction coil windings can also be arranged at two or all three positions. Depending on the timing of the packaging machine so that the cutting blade at the position of the longest residence time, or even largely continuously heated. expedient the heating takes place in such a way that the heat losses of the cutting blade are compensated and a constant temperature is maintained.
- the induction coil winding is preferably embedded in an insulating material which has an alternating magnetic field which is produced by the induction coil winding and has a smooth, non-porous surface.
- the winding wire may either be coated with an electrical insulating layer and the induction coil winding as a whole bordered, or the induction coil winding may be cast directly into an electrically insulating material.
- materials for bordering or casting for example, glass-ceramic or resin are used. Especially in food processing, it is desired that the machines used have smooth surfaces which have no tendency for dirt adhesion and are easy to clean.
- the induction coil winding is arranged interchangeably on the packaging machine.
- a defective component can be replaced so cheaply and quickly, whereby longer life of the packaging machine can be avoided.
- the induction coil winding can be inserted, for example, by means of a plug-in connection in recesses provided for forming an electrical contact. Also, the replacement of a one-piece wall cover, as described above, is possible.
- the induction coil winding with an AC voltage having a frequency in the range of about 25 kHz to 50 kHz can be acted upon.
- the energy can be transferred from the induction coil winding to the cutting blade with the best possible efficiency.
- the induction coil winding is dimensioned so that there is no resistance heating by the applied voltage or the applied current.
- the packaging machine comprises two or more induction coil windings, which can be subjected to voltage independently of each other.
- induction coil windings can be arranged in the sealing plate, the shell receptacle and the outer frame of the sealing station.
- the coils can be switched on individually and operated with a respective desired voltage.
- the heat flow and thus the heating power requirement can vary.
- the described packaging machine can thus be used for all product types and production environments, wherein the heating of the induction coil windings is selected so that only the actually required electrical energy is consumed.
- the cutting blade is made of a ferromagnetic material, preferably ferritic stainless steel, in particular stainless steel.
- a ferromagnetic material is particularly suitable. Since the cutting blade may come into contact with water or other liquids due to atmospheric moisture, possible contact with the products to be processed and cleaning of the packaging machine, the cutting blade should not be rusted. On the one hand, the blade would lose its cutting effect due to the formation of rust and on the other hand would no longer meet the hygiene requirements in food processing.
- the proper choice of material, such as ferritic stainless steel prevents rusting and ensures reliable operation of the cutting blade with a consistent cutting performance.
- the use of an induction coil winding enables the sealing plate and the cutting blade to be heated to different temperatures, in particular such that the temperature of the cutting blade is higher than the temperature of the sealing plate.
- the direct heating of the sealing plate can be limited by many factors.
- the film material used determines its processing temperature.
- the temperature for processing the film material may be limited.
- heating of the cutting blade, even if adjacent to the heated sealing plate may not be accomplished to the desired intensity.
- the independent heating of the cutting blade by means of induction coil winding allows the setting of the desired temperature, even if the environment, so the sealing plate, dissipated heat would otherwise be insufficient.
- two temperature zones namely a temperature zone 1 of the cutting blade with a temperature of for example 180 ° C and adjacent to a temperature zone 2 of the sealing plate, in particular a pressing surface, for example, 130 ° C are formed.
- a temperature sensor is present on the cutting blade and / or the sealing plate. This allows the exact monitoring and thus adjustment of the heating power of the induction coil winding.
- the temperature of the sealing plate which has a separate, not explained in detail heating, can be adjusted. It can thus be provided the energy that is needed, and a too hot or too cold cutting blade and sealing plate is avoided by the heat outputs are readjusted in deviations from the desired temperatures.
- the cutting blade can be heated to a temperature in the range of 150 ° C to 200 ° C. Also, depending on the film material used, a temperature is selected which provides an optimal cutting result. At the same time, care is taken that the shell to be closed is not affected by too high a cutting blade temperature. Also, to avoid unnecessarily high energy consumption, no higher than the actual required temperature is set.
- the packaging machine has an electronic control system which automatically controls the heating of the cutting blade and / or the sealing plate.
- a temperature specification for heating the cutting blade and the sealing plate of the packaging machine can be transferred by means of the customary operator terminals or data input devices.
- the electronic control system can then monitor the actual temperatures and automatically correct for deviations from the preset by adjusting the heating power of the induction coil windings and heating the sealing plate.
- the packaging process can run fully automatically resulting in a work easier for a surgeon and delivers a consistent result.
- the cutting blade has a distance in the range of 0.1 mm to 3.0 mm from the induction coil winding, which is arranged in the sealing plate and / or in the outer frame of the sealing station on.
- the distances are chosen so that the magnetic field generated by the induction coil winding optimally in the cutting blade couples.
- attention is paid to a compact design of the packaging machine and the possibility of cleaning or replacement of the cutting blade maintained.
- the distances to the adjacent components also ensure a non-contact movement of the cutting blade.
- the sealing tool is adapted to evacuate the shell.
- vacuum channels are present in the relevant components, through which the air is removed from the shell by means of a vacuum pump.
- a particularly good shelf life of the packaged product can be achieved.
- the gasification with a protective gas is possible, which further slows down an aging process of the product.
- the sealing tool is adapted to close the shell by deep drawing the sheet material and sealing the shell with the sheet material.
- the deep drawing process places the film flush over the shell and the product contained therein, forming a vacuum, thereby achieving a longer shelf life.
- the deep drawing process offers the possibility of a particularly appealing product presentation.
- FIG. 1 shows a section of an embodiment of a packaging machine 1 according to the invention in a lateral sectional view.
- a manufacturing step in which a supplied from a conveyor belt shell 11 rests by lowering a support table 13 with its lateral horizontal edges 15 on the tray receptacle 7 and the seal or the film cut has not yet taken place.
- the shell 11 is lifted by the support table 13 again and can be transported by a conveyor mechanism.
- the shell 11 is closed by lowering an outer frame 17 and the sealing plate 9 with a film material 19.
- a cutting blade 23 is lowered to cut the film material 19.
- a sealing station 3 is shown, but it will be understood that a packaging machine 1 may comprise a plurality of sealing stations 3 for the simultaneous processing of a plurality of trays 11.
- an induction coil winding 25 is arranged in each case.
- this is shown for a left and a right side of the sealing station 3, but it is understood that corresponding induction coil windings 25 are also present for a front and a rear side.
- the size of the induction coil windings 25 can vary depending on the desired heating power.
- FIG. 2 shows an enlarged view of the left side of the sealing station 3 from FIG. 1 , Also visible is a manufacturing step prior to sealing the shell 11 with the film material 19.
- the sealing plate 9 is already lowered and would press the film material 19 on the horizontal edge 15 of the shell 11 by further lowering.
- Induction coil windings 25 are arranged in the shell receptacle 7, the sealing plate 9 and the outer frame 17. These serve to heat the cutting blade 23, which after sealing the shell 11 by a downward movement, the film material 19 cuts.
- the induction coil windings 25 can have different sizes. Thus, it may be advantageous, for example, to dimension them slightly larger at a greater distance between the cutting blade 23 and the induction coil winding 25.
- the induction coil windings 25 close flush and without gaps with the receiving components (tray receptacle 7, sealing plate 9, outer frame 17). This can, as described above, either by exact fitting into corresponding recesses, or by a full-surface cladding of the components 7, 9, 17 or integrally finished the outer contour thereof. In the latter case, the induction coil windings 25 are accessible from the production side facing away from sides. Evident are also individual winding wires 27, which are cast in an electrically insulating filling material 29, for example a resin. To monitor the actual temperature of the cutting blade 23 and / or sealing plate 9 is used in each case a temperature sensor 31, which transmits the measured values to an electronic control system 33. The electronic control system 33 can then automatically regulate the heating power of the induction coil windings 25 as well as the heating of the sealing plate 9 automatically.
- the packaging machine 1 can each be adapted to different shell shapes.
- the cutting tool 21 may be adjusted so that it only cuts the film material 19 or even the horizontal edge 15 of the shell 11.

Description
Die vorliegende Erfindung betrifft eine Verpackungsmaschine, insbesondere eine Schalenversiegelungsmaschine, mit einem Schneidwerkzeug.The present invention relates to a packaging machine, in particular a tray sealing machine, with a cutting tool.
Versiegelte Verpackungen, insbesondere Kunststoffverpackungen, finden für weitestgehend alle Produktgattungen Verwendung. Häufig werden frische Lebensmittelprodukte in eine tiefgezogene Kunststoffschale eingelegt oder portioniert und anschließend die Schale mit einer Kunststofffolie mittels einer Heißsiegelnaht, Schweißnaht oder Haftklebenaht luftdicht verschlossen. Das dafür verwendete Siegelwerkzeug, insbesondere die Siegelplatte, ist dazu üblicherweise beheizt und drückt an den Rändern der Schale die Kunststofffolie auf selbige, um beide miteinander zu verbinden. Die Kunststofffolie kann ebenfalls unter Ausbildung eines Vakuums tiefgezogen werden und sich so über das Produkt legen. Besonders geeignet für diese Art der Versiegelung sind sogenannte "Skinfolien", welche besonders flexibel sind und sich eng über das Produkt in der Schale legen. Da die Folie zumeist kontinuierlich von einer Rolle zugeführt wird, muss nach dem Versiegelungsvorgang die Folie an den Rändern der Schale geschnitten werden. Wie aus der
Aufgabe der Erfindung ist es, eine Verpackungsmaschine mit einem Siegelwerkzeug und einem verbesserten Schneidwerkzeug bereitzustellen.The object of the invention is to provide a packaging machine with a sealing tool and an improved cutting tool.
Die Aufgabe wird gelöst durch eine Verpackungsmaschine mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.
Eine erfindungsgemäße Verpackungsmaschine, insbesondere eine Schalenversiegelungsmaschine, umfasst eine Siegelstation, die ein Siegelwerkzeug mit einer Schalenaufnahme und einer Siegelplatte zum gasdichten Verschließen einer Schale mit einem Folienmaterial sowie ein Schneidwerkzeug zum Schneiden des Folienmaterials aufweist. Desweiteren umfassen die Verpackungsmaschine mindestens eine Induktionsspulenwicklung und das Schneidwerkzeug eine Schneidklinge, wobei die mindestens eine Induktionsspulenwicklung dazu konfiguriert ist, die Schneidklinge induktiv zu beheizen. Wie dies aus anderen technischen Bereichen, wie zum Beispiel dem Induktionsherd, bekannt ist, überträgt das Prinzip der magnetischen Induktion die elektrische Energie der an die Induktionsspulenwicklung angelegten Wechselspannung berührungslos durch ein sich veränderndes Magnetfeld auf einen räumlich benachbarten, aber von der Induktionsspulenwicklung elektrisch isolierten, Werkstoff, in diesem Fall die Schneidklinge des Schneidwerkzeugs. In der Schneidklinge werden durch das von der Induktionsspulenwicklung erzeugte magnetische Wechselfeld Wirbelströme induziert, welche aufgrund des elektrischen Widerstands des Werkstoffs zu einer Erwärmung der Schneidklinge führen. Die Beheizung eines Werkstoffs mittels magnetischer Induktion stellt einen deutlich energieeffizienteren Prozess als beispielsweise die Übertragung thermischer Energie von einer widerstandsbeheizten Spulenwicklung dar. Somit kann bei niedrigem Energieverbrauch die Schneidklinge auf eine gewünschte Temperatur gebracht und die Temperatur dauerhaft beibehalten werden. Die Schneidklinge kann so unabhängig von einer Beheizung der Siegelplatte auf einer für das Schneiden der Folie vorteilhaften Temperatur gehalten werden. So ergibt sich ein verbessertes und gleichbleibend hochwertiges Schnittbild. Auch die benötigte Schneidkraft verringert sich, was vorteilhaft für die verwendete Mechanik ist und den Verschleiß der Schneidklinge reduziert. Dabei kann das Schneidwerkzeug derart eingestellt sein, dass entweder nur die Folie oder die Folie und ein horizontaler Rand der Schale formgebend geschnitten werden. Während der Versiegelung und des Schneidens der Folie liegt die Schale mit ihrem horizontalen Rand auf der Schalenaufnahme auf, womit die nötige mechanische Gegenkraft gegeben ist.The object is achieved by a packaging machine with the features of
A packaging machine according to the invention, in particular a tray sealing machine, comprises a sealing station which has a sealing tool with a tray receptacle and a sealing plate for the gas-tight sealing of a tray with a film material and a cutting tool for cutting the film material. Furthermore, the packaging machine comprises at least one induction coil winding and the cutting tool comprises a cutting blade, wherein the at least one induction coil winding is configured to inductively heat the cutting blade. As is known from other technical fields, such as the induction cooker, the principle of magnetic induction transmits the electrical energy of the voltage applied to the induction coil winding non-contact by a changing magnetic field on a spatially adjacent, but electrically isolated from the induction coil winding material, in this case the cutting blade of the cutting tool. In the cutting blade eddy currents are induced by the magnetic field generated by the induction coil winding, which lead to a heating of the cutting blade due to the electrical resistance of the material. The heating of a material by means of magnetic induction is a much more energy-efficient process than, for example, the transmission of thermal energy from a resistance-heated coil winding. Thus, with low energy consumption, the cutting blade can be brought to a desired temperature and the temperature permanently maintained. The cutting blade can thus be kept independent of a heating of the sealing plate on a favorable for cutting the film temperature. This results in an improved and consistently high-quality cut. The required cutting force is reduced, which is advantageous for the mechanics used and reduces the wear of the cutting blade. In this case, the cutting tool can be adjusted so that either only the film or the film and a horizontal edge of the shell are cut shaping. During the sealing and cutting of the film, the shell lies with its horizontal edge on the shell receptacle, whereby the necessary mechanical counterforce is given.
In einer zweckmäßigen Variante ist die mindestens eine Induktionsspulenwicklung in der Siegelplatte und/oder in der Schalenaufnahme und/oder in einem die Siegelplatte aufnehmenden Außenrahmen der Siegelstation angeordnet. Wie weiter unten in der Figurenbeschreibung erläutert, sollte die Induktionsspulenwicklung ohne direkten Kontakt zur Schneidklinge, aber räumlich benachbart zu dieser angeordnet sein. Die Induktionsspulenwicklung kann z. B. mit ihrem Querschnitt parallel zur Fläche der Schneidklinge in einer Aussparung der Siegelplatte und/oder des Außenrahmens der Siegelstation angeordnet sein und somit die Schneidklinge hauptsächlich in ihrer oberen Ruheposition beheizen. Auch in der Schalenaufnahme, also dem unteren Teil der Siegelstation, auf welchem der horizontale Rand der Schale aufliegt, kann die Induktionsspulenwicklung angeordnet sein. Eine Beheizung der Schneidklinge findet in diesem Fall während der Annäherung und des Kontakts der Schneidklinge mit der Schalenaufnahme bzw. des horizontalen Rands der Schale zum Schneiden des Folienmaterials statt. Es versteht sich, dass auch an zweien oder allen drei Positionen Induktionsspulenwicklungen angeordnet sein können. Je nach Taktung der Verpackungsmaschine kann damit die Schneidklinge an der Position der längsten Verweildauer, oder sogar weitestgehend kontinuierlich, beheizt werden. Zweckmäßig erfolgt die Beheizung derart, dass die Wärmeverluste der Schneidklinge ausgeglichen und eine konstante Temperatur gehalten wird.In an expedient variant, the at least one induction coil winding in the sealing plate and / or in the shell receptacle and / or in a sealing plate receiving the outer frame of the sealing station is arranged. As explained further below in the description of the figures, the induction coil winding should be arranged without direct contact with the cutting blade, but spatially adjacent to it. The induction coil winding can, for. B. be arranged with its cross-section parallel to the surface of the cutting blade in a recess of the sealing plate and / or the outer frame of the sealing station and thus heat the cutting blade mainly in its upper rest position. Also in the shell receptacle, so the lower part of the sealing station, on which rests the horizontal edge of the shell, the induction coil winding can be arranged. Heating of the cutting blade in this case takes place during the approach and contact of the cutting blade with the tray receptacle or the horizontal edge of the tray for cutting the film material. It is understood that induction coil windings can also be arranged at two or all three positions. Depending on the timing of the packaging machine so that the cutting blade at the position of the longest residence time, or even largely continuously heated. expedient the heating takes place in such a way that the heat losses of the cutting blade are compensated and a constant temperature is maintained.
Vorzugsweise ist die Induktionsspulenwicklung in ein isolierendes, ein von der Induktionsspulenwicklung erzeugtes magnetisches Wechselfeld leitendes und eine glatte, porenfreie Oberfläche aufweisendes Material eingebettet. Der Wicklungsdraht kann entweder mit einer elektrischen Isolationsschicht überzogen und die Induktionsspulenwicklung als Ganzes eingefasst sein, oder die Induktionsspulenwicklung kann direkt in ein elektrisch isolierendes Material eingegossen sein. Als Materialen zum Einfassen oder Eingießen finden zum Beispiel Glaskeramik oder Harz Verwendung. Besonders in der Lebensmittelverarbeitung ist es gewünscht, dass die verwendeten Maschinen glatte Oberflächen aufweisen, welche keine Tendenz zur Schmutzanhaftung haben und leicht zu reinigen sind. Durch die Kapselung der Induktionsspulenwicklungen können sich keine Verunreinigungen an den Windungen absetzen und die Integration derartiger Induktionsspulenwicklungen in die vorhandenen Flächen, wie Siegelplatte oder Außenrahmen, erhält diese Flächen weiterhin eben und ohne Vorsprünge. Ein Eingießen der Induktionsspulenwicklung in ein Harz ermöglicht besonders einfach die Realisierung der gewünschten Außenabmessungen des entstehenden Spulenblocks und isoliert gleichzeitig den Wicklungsdraht. Alternativ dazu können die Flächen von Siegelplatte und Außenrahmen auch als Ganzes eine einstückige Abdeckung der darunter befindlichen Bauteile und gleichzeitig für das magnetische Feld der Induktionsspulenwicklung durchlässig sein.The induction coil winding is preferably embedded in an insulating material which has an alternating magnetic field which is produced by the induction coil winding and has a smooth, non-porous surface. The winding wire may either be coated with an electrical insulating layer and the induction coil winding as a whole bordered, or the induction coil winding may be cast directly into an electrically insulating material. As materials for bordering or casting, for example, glass-ceramic or resin are used. Especially in food processing, it is desired that the machines used have smooth surfaces which have no tendency for dirt adhesion and are easy to clean. The encapsulation of the induction coil windings, no impurities can settle on the windings and the integration of such induction coil windings in the existing surfaces, such as sealing plate or outer frame, these surfaces continue to receive flat and without projections. Pouring the induction coil winding into a resin makes it particularly easy to realize the desired outer dimensions of the resulting coil block and simultaneously isolates the winding wire. Alternatively, the surfaces of the sealing plate and outer frame as a whole may be integral with the underlying components and at the same time permeable to the magnetic field of the induction coil winding.
In einer vorteilhaften Variante ist die Induktionsspulenwicklung austauschbar an der Verpackungsmaschine angeordnet. Ein defektes Bauteil kann so kostengünstig und schnell ersetzt werden, wodurch längere Standzeiten der Verpackungsmaschine vermieden werden. Die Induktionsspulenwicklung kann zum Beispiel mittels einer Steckverbindung in dafür vorgesehene Aussparungen unter Ausbildung eines elektrischen Kontakts eingesteckt werden. Auch der Austausch hinter einer einstückigen Wandabdeckung, wie oben beschrieben, ist möglich.In an advantageous variant, the induction coil winding is arranged interchangeably on the packaging machine. A defective component can be replaced so cheaply and quickly, whereby longer life of the packaging machine can be avoided. The induction coil winding can be inserted, for example, by means of a plug-in connection in recesses provided for forming an electrical contact. Also, the replacement of a one-piece wall cover, as described above, is possible.
Üblicherweise ist die Induktionsspulenwicklung mit einer Wechselspannung mit einer Frequenz im Bereich von ca. 25 kHz bis 50 kHz beaufschlagbar. Durch die Wahl einer geeigneten Spannungsquelle und einer geeigneten Frequenz kann die Energie mit bestmöglichem Wirkungsgrad von der Induktionsspulenwicklung auf die Schneidklinge übertragen werden. Die Induktionsspulenwicklung ist dabei so dimensioniert, dass es zu keiner Widerstandserwärmung durch die angelegte Spannung bzw. den angelegten Strom kommt.Usually, the induction coil winding with an AC voltage having a frequency in the range of about 25 kHz to 50 kHz can be acted upon. By choosing a suitable voltage source and a suitable frequency, the energy can be transferred from the induction coil winding to the cutting blade with the best possible efficiency. The induction coil winding is dimensioned so that there is no resistance heating by the applied voltage or the applied current.
In einer zweckmäßigen Variante umfasst die Verpackungsmaschine zwei oder mehrere Induktionsspulenwicklungen, wobei diese unabhängig voneinander mit Spannung beaufschlagbar sind. So können in der Siegelplatte, der Schalenaufnahme und dem Außenrahmen der Siegelstation Induktionsspulenwicklungen angeordnet sein. Je nach Heizleistungsbedarf können die Spulen einzeln zugeschaltet und mit jeweils einer gewünschten Spannung betrieben werden. Insbesondere in Abhängigkeit der zu verarbeitenden Produkte kann der Wärmeabfluss und damit der Heizleistungsbedarf variieren. So macht die Verarbeitung von Kühlprodukten, möglicherweise in einer gekühlten Umgebung, eine höhere Heizleistung notwendig als beispielsweise die Abfüllung von zuvor erhitzten Fertiggerichten. Die beschriebene Verpackungsmaschine ist also für alle Produktgattungen und Fertigungsumgebungen verwendbar, wobei die Beheizung der Induktionsspulenwicklungen so gewählt wird, dass nur die tatsächlich benötigte elektrische Energie verbraucht wird.In an expedient variant, the packaging machine comprises two or more induction coil windings, which can be subjected to voltage independently of each other. Thus, induction coil windings can be arranged in the sealing plate, the shell receptacle and the outer frame of the sealing station. Depending on the heating power requirement, the coils can be switched on individually and operated with a respective desired voltage. In particular, depending on the products to be processed, the heat flow and thus the heating power requirement can vary. Thus, the processing of refrigerated products, possibly in a refrigerated environment, requires a higher heat output than, for example, the filling of previously heated ready meals. The described packaging machine can thus be used for all product types and production environments, wherein the heating of the induction coil windings is selected so that only the actually required electrical energy is consumed.
In einer typischen Variante ist die Schneidklinge aus einem ferromagnetischen Material, bevorzugt ferritischem rostfreien Stahl, insbesondere Edelstahl, gefertigt. Zur induktiven Beheizung eines Werkstoffs und damit der Erzeugung von Wirbelströmen darin ist ein ferromagnetisches Material besonders geeignet. Da die Schneidklinge durch die Luftfeuchtigkeit, den eventuellen Kontakt mit den zu verarbeitenden Produkten sowie die Reinigung der Verpackungsmaschine in Kontakt mit Wasser oder anderen Flüssigkeiten kommen kann, sollte ein Rosten der Schneidklinge vermieden werden. Die Klinge würde durch das Ausbilden von Rost einerseits ihre Schneidwirkung verlieren und andererseits den Hygieneanforderungen in der Lebensmittelverarbeitung nicht mehr genügen. Durch die geeignete Materialwahl, zum Beispiel ferritischer, rostfreier Edelstahl, kann ein Rosten verhindert und ein zuverlässiger Betrieb der Schneidklinge mit einer konstanten Schneidleistung sichergestellt werden.In a typical variant, the cutting blade is made of a ferromagnetic material, preferably ferritic stainless steel, in particular stainless steel. For inductive heating of a material and thus the generation of eddy currents therein a ferromagnetic material is particularly suitable. Since the cutting blade may come into contact with water or other liquids due to atmospheric moisture, possible contact with the products to be processed and cleaning of the packaging machine, the cutting blade should not be rusted. On the one hand, the blade would lose its cutting effect due to the formation of rust and on the other hand would no longer meet the hygiene requirements in food processing. The proper choice of material, such as ferritic stainless steel, prevents rusting and ensures reliable operation of the cutting blade with a consistent cutting performance.
Der Einsatz einer Induktionsspulenwicklung ermöglicht es, dass die Siegelplatte und die Schneidklinge auf unterschiedliche Temperaturen beheizbar sind, insbesondere derart, dass die Temperatur der Schneidklinge höher als die Temperatur der Siegelplatte ist. Die direkte Beheizung der Siegelplatte kann durch vielerlei Faktoren begrenzt sein. So bestimmt das verwendete Folienmaterial seine Verarbeitungstemperatur. Auch wegen besonders empfindlicher Lebensmittelprodukte kann die Temperatur zur Verarbeitung des Folienmaterials begrenzt sein. Demzufolge kann die Beheizung der Schneidklinge, auch wenn diese benachbart zur beheizten Siegelplatte angeordnet ist, möglicherweise nicht in der gewünschten Intensität erfolgen. Die eigenständige Beheizung der Schneidklinge mittels Induktionsspulenwicklung ermöglicht hingegen die Einstellung der gewünschten Temperatur, auch wenn die von der Umgebung, also der Siegelplatte, dissipierte Wärme ansonsten nicht ausreichend wäre. So können zwei Temperaturzonen, nämlich eine Temperaturzone 1 der Schneidklinge mit einer Temperatur von zum Beispiel 180°C und benachbart dazu eine Temperaturzone 2 der Siegelplatte, insbesondere einer Andrückfläche, von zum Beispiel 130°C ausgebildet werden.The use of an induction coil winding enables the sealing plate and the cutting blade to be heated to different temperatures, in particular such that the temperature of the cutting blade is higher than the temperature of the sealing plate. The direct heating of the sealing plate can be limited by many factors. Thus, the film material used determines its processing temperature. Also, because of particularly sensitive food products, the temperature for processing the film material may be limited. As a result, heating of the cutting blade, even if adjacent to the heated sealing plate, may not be accomplished to the desired intensity. The independent heating of the cutting blade by means of induction coil winding, however, allows the setting of the desired temperature, even if the environment, so the sealing plate, dissipated heat would otherwise be insufficient. Thus, two temperature zones, namely a
Besonders vorteilhaft ist es, wenn an der Schneidklinge und/oder der Siegelplatte ein Temperatursensor vorhanden ist. Dies ermöglicht die exakte Überwachung und damit Einstellung der Heizleistung der Induktionsspulenwicklung. Auch die Temperatur der Siegelplatte, welche durch eine separate, hier nicht näher erläuterte Beheizung verfügt, kann so eingestellt werden. Es kann so die Energie bereitgestellt werden, die benötigt wird, und eine zu heiße oder zu kalte Schneidklinge und Siegelplatte wird vermieden, indem bei Abweichungen von den gewünschten Temperaturen die Heizleistungen nachgeregelt werden.It is particularly advantageous if a temperature sensor is present on the cutting blade and / or the sealing plate. This allows the exact monitoring and thus adjustment of the heating power of the induction coil winding. The temperature of the sealing plate, which has a separate, not explained in detail heating, can be adjusted. It can thus be provided the energy that is needed, and a too hot or too cold cutting blade and sealing plate is avoided by the heat outputs are readjusted in deviations from the desired temperatures.
In einer üblichen Variante ist die Schneidklinge auf eine Temperatur im Bereich von 150°C bis 200°C beheizbar. Auch in Abhängigkeit des verwendeten Folienmaterials wird eine Temperatur gewählt, welche ein optimales Schnittergebnis liefert. Gleichzeitig wird darauf geachtet, dass die zu verschließende Schale nicht durch eine zu hohe Schneidklingentemperatur beeinträchtigt wird. Auch um einen unnötig hohen Energieverbrauch zu vermeiden, wird keine höhere als die tatsächlich benötigte Temperatur eingestellt.In a conventional variant, the cutting blade can be heated to a temperature in the range of 150 ° C to 200 ° C. Also, depending on the film material used, a temperature is selected which provides an optimal cutting result. At the same time, care is taken that the shell to be closed is not affected by too high a cutting blade temperature. Also, to avoid unnecessarily high energy consumption, no higher than the actual required temperature is set.
In einer bevorzugten Variante weist die Verpackungsmaschine ein elektronisches Steuerungssystem auf, welches die Beheizung der Schneidklinge und/oder der Siegelplatte automatisch regelt. Wie bereits ausgeführt, kann eine Temperaturvorgabe zur Beheizung der Schneidklinge sowie der Siegelplatte der Verpackungsmaschine mittels der üblichen Bedienterminals oder Dateneingabegeräte übergeben werden. Mithilfe der verbauten Temperatursensoren kann dann das elektronische Steuerungssystem die tatsächlichen Temperaturen überwachen und automatisch durch Anpassen der Heizleistung der Induktionsspulenwicklungen und der Beheizung der Siegelplatte Abweichungen von der Vorgabe korrigieren. Somit kann der Verpackungsprozess vollautomatisch ablaufen was zu einer Arbeitserleichterung für einen Operateur führt und ein gleichbleibendes Ergebnis liefert.In a preferred variant, the packaging machine has an electronic control system which automatically controls the heating of the cutting blade and / or the sealing plate. As already stated, a temperature specification for heating the cutting blade and the sealing plate of the packaging machine can be transferred by means of the customary operator terminals or data input devices. Using the built-in temperature sensors, the electronic control system can then monitor the actual temperatures and automatically correct for deviations from the preset by adjusting the heating power of the induction coil windings and heating the sealing plate. Thus, the packaging process can run fully automatically resulting in a work easier for a surgeon and delivers a consistent result.
In einer gängigen Variante weist die Schneidklinge einen Abstand im Bereich von 0,1 mm bis 3,0 mm von der Induktionsspulenwicklung, welche in der Siegelplatte und/oder in dem Außenrahmen der Siegelstation angeordnet ist, auf. Die Abstände sind dabei so gewählt, dass das von der Induktionsspulenwicklung erzeugte magnetische Feld optimal in die Schneidklinge einkoppelt. Zudem wird auf eine kompakte Bauweise der Verpackungsmaschine geachtet und die Möglichkeit zu einer Reinigung oder einem Austausch der Schneidklinge gewahrt. Die Abstände zu den benachbarten Bauteilen stellen zudem eine berührungsfreie Bewegung der Schneidklinge sicher.In a common variant, the cutting blade has a distance in the range of 0.1 mm to 3.0 mm from the induction coil winding, which is arranged in the sealing plate and / or in the outer frame of the sealing station on. The distances are chosen so that the magnetic field generated by the induction coil winding optimally in the cutting blade couples. In addition, attention is paid to a compact design of the packaging machine and the possibility of cleaning or replacement of the cutting blade maintained. The distances to the adjacent components also ensure a non-contact movement of the cutting blade.
Idealerweise ist das Siegelwerkzeug dazu geeignet, die Schale zu evakuieren. Dazu sind in den relevanten Bauteilen Vakuumkanäle vorhanden, durch welche mittels einer Vakuumpumpe die Luft aus der Schale entfernt wird. Dadurch kann eine besonders gute Haltbarkeit des verpackten Produkts erreicht werden. Zusätzlich ist das Begasen mit einem Schutzgas möglich, was einen Alterungsprozess der Ware weiter verlangsamt.Ideally, the sealing tool is adapted to evacuate the shell. For this purpose, vacuum channels are present in the relevant components, through which the air is removed from the shell by means of a vacuum pump. As a result, a particularly good shelf life of the packaged product can be achieved. In addition, the gasification with a protective gas is possible, which further slows down an aging process of the product.
Vorzugsweise ist das Siegelwerkzeug dazu geeignet, die Schale durch ein Tiefziehen des Folienmaterials und ein Versiegeln der Schale mit dem Folienmaterial zu verschließen. Das Tiefziehverfahren legt die Folie unter Ausbildung eines Vakuums bündig über die Schale und das darin enthaltene Produkt, wodurch eine längere Haltbarkeit erreicht wird. Zudem bietet das Tiefziehverfahren die Möglichkeit einer besonders ansprechenden Produktpräsentation. Nachdem die Folie über die Schale gelegt wurde, wird die Folie und die Schale, zumeist an einem oberen, horizontalen Rand, gasdicht verschlossen, indem die beheizte Siegelplatte beide gegen die Schalenaufnahme presst.Preferably, the sealing tool is adapted to close the shell by deep drawing the sheet material and sealing the shell with the sheet material. The deep drawing process places the film flush over the shell and the product contained therein, forming a vacuum, thereby achieving a longer shelf life. In addition, the deep drawing process offers the possibility of a particularly appealing product presentation. After the film has been placed over the shell, the film and the shell, usually at an upper, horizontal edge, sealed gas-tight, by the heated sealing plate both pressed against the shell receptacle.
