  • This allows automated packaging of different sized products, preferably fresh cuts of meat, in wells suitable for the product being transported to the thermoforming packaging machine.
  • the size of a trough is defined by its length, width and depth of the deep draw formed in the forming station in the film web.
  • the products intended for a corresponding trough are shorter in length, width and height than the trough itself.
  • a format is defined by the number and / or the shape of a group of wells generated in a common molding operation.
  • a format also approximates the dimension of the mold and has a length that corresponds to the intermittent preference of the film web.
  • a first sealing station is provided to seal a format having one or more wells with a lid film by means of at least one frame seal.

  • product feature such as product size
  • thermoformed packaging can be achieved by gassing or by gas rinsing.
  • the product feature is at least one dimension of the product, such as its height, length and / or width.
  • the troughs produced in a forming station may have a predetermined length and width, while the depth of the trough is adaptable to the height of the product in known manner.
  • the distribution device distributes the products according to their product feature on the respective transport device, in order to allow easy sorting and / or grouping.
  • the products located on the conveyor are buffered at a collector before the product is loaded by the collector at the infeed station into the trough. This allows a simplification of the control of the transport devices and the product tracking.
  • one or more products are picked up by the transport device and returned to the transport device in order to group the products provided for a format.
  • the products or their position from the inspection station along the feeder, the transport devices and the buffer device to the thermoforming packaging machine are tracked (product tracking) to control and coordinate the forming stations according to the position and transport history of the individual products.
  • products which differ in a product feature are transported together on a transport device to the insertion station of the thermoforming packaging machine and formed for each product format or trough by means of one of two mold stations and merged with the associated product in the insertion station approximately simultaneously.
  • the invention provides that each individual section of the film web for the wells is deep-drawn to wells at exactly one of the forming stations. A deep-drawn already in the first forming station section is thus transported through the subsequent (s) forming station (s) without deformation. It is advantageous if, beyond the last forming station, each section of the film web has been formed into depressions.
  • the inspection station can have an automatically operating checking device for detecting the at least one product feature.

Description

Die Erfindung bezieht sich auf eine Verpackungsanlage und ein Verfahren zum Verpacken von unterschiedlich großen Produkten, beispielsweise Frischfleisch, mit den Merkmalen des Anspruchs 1 bzw. des Anspruchs 9.The invention relates to a packaging installation and a method for packaging products of different sizes, for example fresh meat, having the features of claim 1 and claim 9, respectively.

Aus der WO 2002/016210 A1 ist eine Verpackungslinie zum Verpacken von Fleischstücken in Beuteln bekannt. Dabei werden die individuellen Fleischstücke, die sich vor allem in ihrer Größe unterscheiden, von einer Informationserfassungsstufe erfasst und dann einer Verpackungsstation zugeführt. An der Verpackungsstation wird ein zur Größe des Fleischstücks passender Beutel bereitgestellt und das Fleischstück verpackt. Bei einer Ausführung mit mehreren Verpackungsstationen ist nach der Informationserfassungsstufe eine Einrichtung zum Verteilen der Fleischstücke vorgesehen, um die Fleischstücke beispielsweise nach ihrer Größe sortiert auf die verschiedenen Verpackungsstationen zu verteilen. Nachteilig an einer solchen Beutelverpackungsanlage sind ihre begrenzte Leistung und das optische Aussehen einer Beutelverpackung.From the WO 2002/016210 A1 For example, a packaging line is known for packaging pieces of meat in bags. The individual pieces of meat, which differ mainly in their size, are detected by an information acquisition stage and then fed to a packaging station. At the packing station, a bag matching the size of the piece of meat is provided and the piece of meat is packed. In an embodiment with a plurality of packaging stations, a device for distributing the pieces of meat is provided after the information acquisition stage in order to distribute the pieces of meat sorted according to their size, for example, to the various packaging stations. A disadvantage of such a bagging system is its limited performance and the visual appearance of a bag packaging.

Aufgabe der vorliegenden Erfindung ist es, eine verbesserte Verpackungsanlage bereitzustellen.The object of the present invention is to provide an improved packaging system.

Diese Aufgabe wird gelöst durch eine Verpackungsanlage zum Verpacken von unterschiedlich großen Produkten mit den Merkmalen des Anspruchs 1 und durch ein Verfahren zum Betrieb einer solchen Verpackungsanlage gemäß Anspruch 9.This object is achieved by a packaging installation for packaging products of different sizes with the features of claim 1 and by a method for operating such a packaging installation according to claim 9.

Die erfindungsgemäße Verpackungsanlage zum Verpacken von unterschiedlich großen Produkten, vorzugsweise Lebensmitteln, im Besonderen Frischfleischstücken, umfasst eine Zuführeinrichtung für die Produkte, die wenigstens ein unterscheidbares Produktmerkmal aufweisen. Die Verpackungsanlage umfasst des Weiteren eine Prüfstation zum Erfassen des wenigstens einen Produktmerkmals und eine Verteileinrichtung zum Verteilen der Produkte auf wenigstens zwei Transporteinrichtungen. Die erfindungsgemäße Verpackungsanlage zeichnet sich dadurch aus, dass wenigstens eine Tiefziehverpackungsmaschine mit einer ersten und einer zweiten Formstation vorgesehen ist, wobei mittels der ersten Formstation eine erste Größe von Mulden in eine Folienbahn formbar (d.h. tiefziehbar) ist und mittels der zweiten Formstation eine zur ersten Größe unterschiedliche zweite Größe von Mulden in die Folienbahn formbar (tiefziehbar) ist. Die Tiefziehverpackungsmaschine umfasst eine Steuerung, die dazu konfiguriert ist, im laufenden Betrieb in Abhängigkeit der angelieferten Produkte automatisch umstellbar eine erste oder zweite Größe von Mulden zum Einlegen der entsprechenden Produkte bereitzustellen. Dies ermöglicht ein automatisiertes Verpacken von unterschiedlich großen Produkten, bevorzugt Frischfleischstücken, in passend für das jeweilig an die Tiefziehverpackungsmaschine transportierte Produkt dimensionierte Mulden. So kann eine sehr hohe Leistung erzielt werden, wobei die unterschiedlich großen Mulden entsprechend der angelieferten Produkte erzeugt und an einer Einlegestation automatisch bereitgestellt werden. Die Größe einer Mulde ist durch ihre Länge, Breite und Tiefe des in der Formstation in die Folienbahn geformten Tiefzug definiert. Die Produkte, die für eine entsprechende Mulde vorgesehen sind, weisen eine geringere Länge, Breite und Höhe als die Mulde selbst auf. Ein Format ist durch die Anzahl und/oder die Form einer Gruppe von Mulden definiert, die bei einem gemeinsamen Formvorgang erzeugt werden. Ein Format entspricht auch annähernd der Abmessung des Formwerkzeugs und weist eine Länge auf, die dem intermittierenden Vorzug der Folienbahn entspricht.The packaging installation according to the invention for packaging products of different sizes, preferably foods, in particular fresh meat pieces, comprises a feed device for the products which have at least one distinguishable product feature. The packaging system further comprises a testing station for detecting the at least one product feature and a distribution device for distributing the products on at least two transport devices. The packaging system according to the invention is characterized in that at least one thermoforming packaging machine is provided with a first and a second forming station, wherein by means of the first forming station, a first size of wells in a film web formable (ie deep-drawable) and by means of the second forming station to the first size different second size of wells in the film web formable (thermoformable) is. The thermoforming packaging machine includes a controller configured to automatically provide, during operation, a first or second size of wells for loading the respective products depending on the products supplied. This allows automated packaging of different sized products, preferably fresh cuts of meat, in wells suitable for the product being transported to the thermoforming packaging machine. Thus, a very high performance can be achieved, wherein the different sized wells are generated according to the delivered products and automatically provided at an insertion station. The size of a trough is defined by its length, width and depth of the deep draw formed in the forming station in the film web. The products intended for a corresponding trough are shorter in length, width and height than the trough itself. A format is defined by the number and / or the shape of a group of wells generated in a common molding operation. A format also approximates the dimension of the mold and has a length that corresponds to the intermittent preference of the film web.

Bevorzugt ist eine erste Siegelstation vorgesehen, um ein Format, das ein oder mehrere Mulden aufweist, mit einer Deckelfolie mittels wenigstens einer Rahmensiegelung zu versiegeln. Die Rahmensiegelung in Form einer außen am Format umlaufenden geschlossenen Siegelnaht sorgt dafür, dass eine modifizierte Atmosphäre (Schutzgasatmosphäre) im Inneren der Verpackung mit einem oder mehreren Produkten für die weiteren Prozessschritte erhalten bleibt.Preferably, a first sealing station is provided to seal a format having one or more wells with a lid film by means of at least one frame seal. The frame sealing in the form of a sealed seal around the outside of the format ensures that a modified atmosphere (protective gas atmosphere) is retained inside the packaging with one or more products for the further process steps.

In einer besonders vorteilhaften Ausführung weist die Tiefziehverpackungsmaschine eine zweite Siegelstation zum Erzeugen einer Quer- und/oder Längssiegelung auf, um bereits zwei geformte Mulden innerhalb eines Formats zu zwei eigenständigen Verpackungen zu siegeln.In a particularly advantageous embodiment, the thermoforming packaging machine has a second sealing station for producing a transverse and / or longitudinal sealing in order to already seal two molded hollows within a format into two separate packages.

Vorzugsweise ist die zweite Siegelstation in einer Transportrichtung stromabwärts der ersten Siegelstation angeordnet, da bei dieser Konfiguration die modifizierte Atmosphäre, die in der ersten Siegelstation erzeugt wurde, erhalten bleibt und keine weiteren Maßnahmen bezüglich der Atmosphäre in den Verpackungen erforderlich sind.Preferably, the second sealing station is located in a transport direction downstream of the first sealing station, since in this configuration the modified atmosphere created in the first sealing station is maintained and no further action is required on the atmosphere in the packages.

Wenigstens eine Transporteinrichtung weist bevorzugt eine Puffereinrichtung auf, um ein oder mehrere Produkte von der Transporteinrichtung aufzunehmen und zeitversetzt wieder an die Transporteinrichtung abzugeben. So können Produkte einer ersten Sorte, die in Transportrichtung nicht aufeinander folgen, sondern durch ein Produkt einer anderen Sorte getrennt sind, zusammengeführt werden in dem Sinne, dass die für ein Format erforderliche Anzahl von gleichen Produkten als Gruppe der Einlegestation zugeführt werden kann. Somit können die in willkürlicher Reihenfolge auf der Zuführeinrichtung angelieferten Produkte entsprechend der dafür vorgesehenen Formate auf einfache Weise sortiert oder gruppiert werden.At least one transport device preferably has a buffer device in order to receive one or more products from the transport device and deliver them back to the transport device with a time delay. Thus, products of a first variety, which are not consecutive in the direction of transport but separated by a product of a different sort, can be brought together in the sense that the number of identical products required for one format can be supplied as a group to the loading station. Thus, the products delivered in arbitrary order on the feeder can be easily sorted or grouped according to the formats provided therefor.

Vorzugsweise ist die Steuerung dazu konfiguriert, die jeweils aktuelle Position der Produkte von der Prüfeinrichtung entlang der Zuführeinrichtung, der Transporteinrichtungen und (sofern vorhanden) der Puffereinrichtung bis in die Tiefziehverpackungsmaschine zu verfolgen (im Folgenden "Produktverfolgung" genannt), so dass sichergestellt wird, dass die Formstationen entsprechende Mulden formen, die gleichzeitig mit den dafür vorgesehenen Produkten der Einlegstation zugeführt werden. Dabei kann der Wechsel der zwei oder mehr unterschiedlichen Formate bzw. die unterschiedliche Anzahl der Mulden ohne Verlust von Material der Folienbahn, nämlich ohne sogenannte Leertakte, erfolgen.Preferably, the controller is configured to maintain the current position of the products from the tester along the feeder, the transport means and (if any) to track the buffering device into the thermoforming packaging machine (hereinafter referred to as "product tracking") so as to ensure that the forming stations form respective wells which are fed to the loading station simultaneously with the intended products. In this case, the change of two or more different formats or the different number of wells without loss of material of the film web, namely without so-called empty cycles done.

Bevorzugt ist die Steuerung, nämlich als Steuerung der gesamte Verpackungsanlage, ein Teil einer Maschinensteuerung einer Tiefziehverpackungsmaschine und kann die Informationen beispielsweise von der Prüfstation auch an eine weitere Tiefziehverpackungsmaschine weitergeben. Die Steuerung der Formstationen innerhalb der jeweiligen Tiefziehverpackungsmaschine erfolgt bevorzugt über die jeweilige Maschinensteuerung, während die Produktverfolgung nach der Prüfstation entlang der Transporteinrichtungen mittels der Steuerung der gesamten Verpackungsanlage erfolgt.Preferably, the control, namely as a control of the entire packaging system, a part of a machine control of a thermoforming packaging machine and can pass the information, for example, from the test station to another thermoforming packaging machine. The control of the molding stations within the respective thermoforming packaging machine preferably takes place via the respective machine control, while the product tracking to the inspection station takes place along the transport means by means of the control of the entire packaging installation.

In einer besonderen Ausführungsform ist jeweils eine Sammeleinrichtung nach den Transporteinrichtungen angeordnet, um Produkte von den Transporteinrichtungen vor dem Einlegen aufzunehmen. So können aufwendige Ansteuerungen beispielsweise der Geschwindigkeit der einzelnen Transporteinrichtungen entfallen, da durch die Sammeleinrichtungen dafür gesorgt werden kann, dass immer eine ausreichende Anzahl zum Einlegen benötigter Produkte an der Einlegestation bereitsteht.In a particular embodiment, a collecting device is arranged downstream of the transport devices in order to receive products from the transport devices before loading. Thus, expensive controls, for example, the speed of the individual transport devices can be omitted, since it can be ensured by the collection facilities that there is always a sufficient number for inserting required products at the insertion station ready.

Ein erfindungsgemäßes Verfahren zum Betrieb einer Verpackungsanlage, die wenigstens eine Tiefziehverpackungsmaschine, eine Zuführeinrichtung für Produkte und eine Prüfstation umfasst, wobei die z.B. an, entlang oder auf der Zuführeinrichtung vorgesehene Prüfstation wenigstens ein Produktmerkmal eines jeden Produkts ermittelt wird und das Produkt danach mittels einer Verteileinrichtung entsprechend seines ermittelten Produktmerkmals auf eine Transporteinrichtung verteilt wird, zeichnet sich dadurch aus, dass mittels wenigstens zweier Formstationen einer Tiefziehverpackungsmaschine und mittels einer Steuerung, die mit der Prüfstation verbunden ist, in Abhängigkeit der mittels an der Prüfstation erfassten Produkte und entsprechend ihrer Produktmerkmale die entsprechende Größe und/oder Anzahl von Mulden in eine Folienbahn geformt wird. Dies ermöglicht einen vollautomatisierten Betrieb einer Verpackungsanlage, um willkürlich zugeführte Produkte, die bezüglich eines Produktmerkmals, beispielsweise der Größe des Produkts, Unterschiede aufweisen, in speziell für die unterschiedlichen Produktmerkmale vorgesehene Mulden eingelegt und zu einer optisch ansprechenden Tiefziehverpackung in einer modifizierten Atmosphäre verpackt werden können. Im Speziellen ist bei Frischfleischstücken durch ein Begasen oder ein Gasspülen eine längere Haltbarkeit bei Tiefziehverpackungen im Vergleich zu einer Beutelverpackung erreichbar.A method according to the invention for operating a packaging installation which comprises at least one thermoforming packaging machine, a feed device for products and a test station, wherein the test station provided, for example, along or on the feed device is determined at least one product feature of each product and the product is thereafter correspondingly conveyed by means of a distributing device its determined product feature is distributed to a transport device is characterized in that by means of at least two forming stations of a thermoforming packaging machine and by means of a controller which is connected to the test station, depending on the detected by means of the test station products and according to their product characteristics the appropriate size and / or number of wells is formed into a film web. This allows for fully automated operation of a packaging line to randomly feed products that have differences in product feature, such as product size, into wells designed specifically for the different product features and pack into a visually attractive thermoformed package in a modified atmosphere. Particularly In the case of fresh meat pieces, a longer shelf life in thermoformed packaging compared with a bag packaging can be achieved by gassing or by gas rinsing.

Bevorzugt ist das Produktmerkmal mindestens eine Abmessung des Produktes, wie seine Höhe, seine Länge und/oder seine Breite. Die in einer Formstation erzeugten Mulden können eine vorbestimmte Länge und Breite aufweisen, während die Tiefe der Mulde an die Höhe des Produkts in bekannter Form anpassbar ist.Preferably, the product feature is at least one dimension of the product, such as its height, length and / or width. The troughs produced in a forming station may have a predetermined length and width, while the depth of the trough is adaptable to the height of the product in known manner.

Vorzugsweise verteilt die Verteileinrichtung die Produkte gemäß ihres Produktmerkmals auf die jeweilige Transporteinrichtung, um auf einfache Weise eine Sortierung und/oder Gruppierung zu ermöglichen.Preferably, the distribution device distributes the products according to their product feature on the respective transport device, in order to allow easy sorting and / or grouping.

In einer besonderen Ausführungsform werden die auf der Transporteinrichtung befindlichen Produkte an einer Sammeleinrichtung gepuffert, bevor das Produkt von der Sammeleinrichtung an der Einlegestation in die Mulde eingelegt wird. Dies ermöglicht eine Vereinfachung der Steuerung der Transporteinrichtungen und der Produktverfolgung.In a particular embodiment, the products located on the conveyor are buffered at a collector before the product is loaded by the collector at the infeed station into the trough. This allows a simplification of the control of the transport devices and the product tracking.

In einer besonders vorteilhaften Ausführung werden mittels einer Puffereinrichtung einzelne oder mehrere Produkte von der Transporteinrichtung aufgenommen und wieder an die Transporteinrichtung abgegeben, um die für ein Format vorgesehenen Produkte zu gruppieren.In a particularly advantageous embodiment, by means of a buffer device, one or more products are picked up by the transport device and returned to the transport device in order to group the products provided for a format.

Vorzugsweise werden mittels der Steuerung die Produkte bzw. ihre Position von der Prüfstation entlang der Zuführeinrichtung, der Transporteinrichtungen und der Puffereinrichtung bis in die Tiefziehverpackungsmaschine verfolgt (Produktverfolgung), um die Formstationen entsprechend der Position und des Transportverlaufs der einzelnen Produkte anzusteuern und zu koordinieren.Preferably, by means of the control, the products or their position from the inspection station along the feeder, the transport devices and the buffer device to the thermoforming packaging machine are tracked (product tracking) to control and coordinate the forming stations according to the position and transport history of the individual products.

Bevorzugt werden Produkte, die sich in einem Produktmerkmal unterscheiden, gemeinsam auf einer Transporteinrichtung an die Einlegestation der Tiefziehverpackungsmaschine herantransportiert und das für das jeweilige Produkt vorgesehene Format bzw. Mulde mittels einer von zwei Formstationen geformt und mit dem zugehörigen Produkt in der Einlegestation annähernd zeitgleich zusammengeführt.Preferably, products which differ in a product feature are transported together on a transport device to the insertion station of the thermoforming packaging machine and formed for each product format or trough by means of one of two mold stations and merged with the associated product in the insertion station approximately simultaneously.

Zweckmäßig sieht die Erfindung vor, dass jeder einzelne Abschnitt der Folienbahn für die Mulden an genau einer der Formstationen zu Mulden tiefgezogen wird. Ein bereits in der ersten Formstation tiefgezogener Abschnitt wird also durch die nachfolgende(n) Formstation(en) ohne Verformung hindurch transportiert. Günstig ist es, wenn jenseits der letzten Formstation jeder Abschnitt der Folienbahn zu Mulden geformt wurde.Suitably, the invention provides that each individual section of the film web for the wells is deep-drawn to wells at exactly one of the forming stations. A deep-drawn already in the first forming station section is thus transported through the subsequent (s) forming station (s) without deformation. It is advantageous if, beyond the last forming station, each section of the film web has been formed into depressions.

In der erfindungsgemäßen Verpackungsanlage bzw. im erfindungsgemäßen Verfahren kann die Prüfstation eine automatisch arbeitende Prüfeinrichtung zum Erfassen des wenigstens einen Produktmerkmals aufweisen. Zusätzlich oder alternativ dazu kann die Prüfstation eine Eingabeeinheit wie eine Tastatur, einen Touchscreen oder Ähnliches umfassen, an der eine Bedienperson ein optisch bzw. manuell von ihr erfasstes Produktmerkmal auswählen oder eingeben kann. Diese Eingabeeinheit sollte dann vorzugsweise zur Übermittlung der eingegebenen oder ausgegebenen Produktmerkmale mit der Maschinensteuerung der Verpackungsmaschine verbunden sein.In the packaging installation according to the invention or in the method according to the invention, the inspection station can have an automatically operating checking device for detecting the at least one product feature. Additionally or alternatively, the inspection station may include an input unit such as a keyboard, a touch screen, or the like, at which an operator may select or enter a product feature optically or manually sensed thereby. This input unit should then preferably be connected to the machine control of the packaging machine for the purpose of transmitting the input or output product features.

Fig. 1a zeigt eine erfindungsgemäße Verpackungsanlage 1 mit einer Zuführeinrichtung 2, die unterschiedlich große Produkte 3 in Form z.B. von Frischfleischstücken in einer mit einem Pfeil dargestellten Produktionsrichtung P an einer bzw. unter einer Prüfstation 4 vorbei transportiert. Die Prüfstation 4 kann als mindestens ein Produktmerkmal (d.h. eine Eigenschaft des Produkts) erfassende Prüfeinrichtung 4a eine CCD-Kamera, ein Visionsystem oder ein Röntgengerät umfassen, um z.B. die Größe, im Besonderen die Länge und Breite bzw. die Außenabmessungen der Produkte 3 als ein Produktmerkmal zu erfassen und diese Produktmerkmale über Datenund Steuerleitungen L an eine Maschinensteuerung 5 einer stromabwärts in Produktionsrichtung P nachfolgenden Tiefziehverpackungsmaschine 6 zu übergeben. Weitere Produktmerkmale können das Volumen oder das Gewicht des Produkts 3 sein. Im Fall des Gewichts als ein Produktmerkmal kann die Prüfeinrichtung 4a eine Waage sein. Denkbar ist auch, dass die Produkte 3 mit Barcodes versehen mittels eines Scanners als Prüfeinrichtung 4a an der Prüfstation 4 bezüglich ihres Produktmerkmals erfasst werden. Fig. 1a shows a packaging system 1 according to the invention with a feeding device 2, the different sized products 3 in the form of eg fresh meat pieces in a direction shown by an arrow production direction P transported at one or under a test station 4 over. The testing station 4 may include a CCD camera, a vision system or an X-ray machine as at least one product feature (ie a characteristic of the product), for example the size, in particular the length and width or the outer dimensions of the products 3 as a To capture product feature and transfer these product features via data and control lines L to a machine controller 5 downstream of a downstream in the direction of production P thermoforming packaging machine 6. Other product characteristics may be the volume or weight of the product 3. In the case of weight as a product feature, the test device 4a may be a balance. It is also conceivable that the products 3 provided with barcodes are detected by means of a scanner as a test device 4a at the test station 4 with respect to their product feature.

Denkbar ist auch eine Kombination von verschiedenen Prüfeinrichtungen 4a, um mehrere Produktmerkmale zu erfassen. Die Maschinensteuerung 5 der Tiefziehverpackungsmaschine 6 bildet hier gleichzeitig die Steuerung 5 der gesamten Verpackungsanlage 1.Also conceivable is a combination of different testing devices 4a to detect several product features. The machine control 5 of the thermoforming packaging machine 6 simultaneously forms the controller 5 of the entire packaging installation 1.

Fig. 1b zeigt eine alternative Ausführungsform der Prüfstation 4, bei der zusätzlich zu oder statt einer Prüfeinrichtung 4a eine Bedienperson 4c an der Prüfstation 4 vorgesehen ist, um die Produkte 3 zu prüfen und das entsprechende Produktmerkmal an einer Eingabeeinheit 4b der Prüfstation 4 auszuwählen oder einzugeben. Die Eingabeeinheit 4b ist mit der Maschinensteuerung 5 der Tiefziehverpackungsmaschine 6 verbunden. Fig. 1b shows an alternative embodiment of the test station 4, in which, in addition to or instead of a test device 4a, an operator 4c is provided at the test station 4 to check the products 3 and to select or input the corresponding product feature on an input unit 4b of the test station 4. The input unit 4b is connected to the machine controller 5 of the thermoforming packaging machine 6.

In den Figuren 1a und 1b sind eine erste 6 und eine zweite Tiefziehverpackungsmaschine 7 gezeigt, die jeweils zwei unterschiedliche Formate F1/F2 und F3/F4 von tiefgezogenen Mulden 8 in einer beliebigen Abfolge erzeugen können, wobei das erste Format F1, F3 eine einzige große Mulde 8 und das zweite Format F2 bzw. F4 zwei Mulden 8 aufweist. Die zwei Mulden 8 des zweiten Formats F2 sind jeweils annähernd halb so groß in ihrer Öffnungsfläche wie die Mulde 8 des ersten Formats F1. Die insgesamt in der Verpackungsanlage 1 bereitstellbaren vier Formate F1, F2 bzw. die vier unterschiedlichen Größen von Mulden 8 können vier unterschiedlich große Produkte P1 bis P4 aufnehmen. In dieser Darstellung sind die unterschiedlichen Sorten Produkte 3 entsprechend ihrer Größe und Zuordnung mit P1, P2, P3 und P4 gekennzeichnet, wobei die Produkte 3 der Sorten P1 und P2 für die Formate auf der ersten Tiefziehverpackungsmaschine 6 und die Produkte 3 der Sorten P3 und P4 für die Formate auf der zweiten Tiefziehverpackungsmaschine 7 vorgesehen sind.In the FIGS. 1a and 1b For example, a first 6 and a second thermoforming packaging machine 7 are shown, each of which can produce two different formats F1 / F2 and F3 / F4 of deep-drawn wells 8 in any order, wherein the first format F1, F3 is a single large well 8 and the second format F2 or F4 has two wells 8. The two wells 8 of the second format F2 are each approximately half as large in their opening area as the trough 8 of the first format F1. The four formats F1, F2 or the four different sizes of wells 8 that can be provided in the packaging installation 1 can accommodate four products P1 to P4 of different sizes. In this illustration, the different grades of products 3 are identified according to their size and associated with P1, P2, P3 and P4, the products 3 of the grades P1 and P2 for the formats on the first thermoforming packaging machine 6 and the products 3 of grades P3 and P4 are provided for the formats on the second thermoforming packaging machine 7.

Lediglich als Beispiel sei angenommen, dass die Produkte 3 der Sorte bzw. des Typs P1 eine Länge von 20-30 cm und eine Breite von 10-15 cm aufweisen. Die Produkte 3 der zweiten Sorte P2 hingegen haben eine "Länge" von lediglich 3-5 cm und eine ähnliche "Breite" von 10-15 cm wie die Produkte der ersten Sorte P1. Die Produkte der dritten Sorte P3 haben eine Länge von 30-40 cm und eine ähnliche Breite von 10-15 cm wie die Produkte aller übrigen Sorten. Die Produkte der vierten Sorte P4 haben eine "Länge" von 15-20 cm und eine "Breite" von 10-15cm. In anderen Ausführungsformen ist es denkbar, die Produkte 3 nicht nur anhand einer einzigen Dimension zu unterscheiden (d.h. Länge, Höhe oder Breite), sondern anhand ihrer Dimensionen in zwei oder mehr Raumrichtungen. Beispielsweise kann die Unterscheidung in verschiedene Produktsorten P1 bis P4 jeweils anhand der Summe der Abmessungen in zwei oder drei verschiedenen Raumrichtungen erfolgen. In weiteren Varianten ist es denkbar, beispielsweise das Gewicht der Produkte 3 als einziges oder als zusätzliches Unterscheidungsmerkmal zwischen den verschiedenen Sorten P1 bis P4 heranzuziehen.By way of example only, it is assumed that the products 3 of the type or the type P1 have a length of 20-30 cm and a width of 10-15 cm. By contrast, the products 2 of the second variety P2 have a "length" of only 3-5 cm and a similar "width" of 10-15 cm as the products of the first variety P1. The products of the third variety P3 have a length of 30-40 cm and a similar width of 10-15 cm as the products of all other varieties. The products of the fourth variety P4 have a "length" of 15-20 cm and a "width" of 10-15cm. In other embodiments, it is conceivable to distinguish the products 3 not only by a single dimension (ie length, height or width) but by their dimensions in two or more spatial directions. For example, the distinction into different product locations P1 to P4 can be made in each case based on the sum of the dimensions in two or three different spatial directions. In further variants, it is conceivable, for example, to use the weight of the products 3 as the sole or as an additional distinguishing feature between the different types P1 to P4.

Um die Aufteilung der Produkte 3 auf die zwei Tiefziehverpackungsmaschine 6, 7 umzusetzen, ist am Ende der Zuführeinrichtung 2 eine Verteileinrichtung 9 angeordnet. Die Steuerung 5 steuert die Verteileinrichtung 9 entsprechend der von der Prüfstation 4 erhalten Informationen über wenigstens ein Produktmerkmal eines jeden einzelnen Produkts 3. Die Verteileinrichtung 9 sorgt für eine Verteilung oder Sortierung der Produkte 3 auf eine nachfolgende erste 10 und eine zweite Transporteinrichtung 11. Die Verteileinrichtung 9 kann beispielsweise als Picker, Anacondaband oder Weiche ausgeführt sein. Die erste Transporteinrichtung 10 kann ein oder wie in Fig. 1 gezeigt zwei aufeinander folgende Transportbänder aufweisen, um die Produkte 3 der Sorten P1 und P2 der ersten Tiefziehverpackungsmaschine 6 zuzuführen. Analog ist dies für die zweite Transporteinrichtung 11 und die zweite Tiefziehverpackungsmaschine 7 bzw. die Produkte 3 der Sorten P3 und P4 der Fall.In order to implement the division of the products 3 on the two thermoforming packaging machine 6, 7, a distributor 9 is arranged at the end of the feeder 2. The controller 5 controls the distribution device 9 in accordance with the information received from the test station 4 about at least one product feature of each individual product 3. The distribution device 9 provides for a distribution or sorting of the products 3 on a subsequent first 10 and a second transport device 11. The distribution device 9 may be designed for example as a picker, Anacondaband or switch. The first transport device 10 may be one or as in Fig. 1 shown having two successive conveyor belts to supply the products 3 of the types P1 and P2 of the first thermoforming packaging machine 6. Analogously, this is the case for the second transport device 11 and the second thermoforming packaging machine 7 or the products 3 of the grades P3 and P4.

Die Produkte 3 werden von den Transporteinrichtungen 10, 11 bis an Einlegestationen 12 der Tiefziehverpackungsmaschinen 6, 7 herangeführt und manuell oder automatisiert in die an der Einlegestation 12 bereitgestellten Mulden 8 eingelegt. Dabei werden die Mulden 8 mittels Formstationen 22, 23, die in Fig. 2 näher dargestellt sind, erzeugt, wobei die Zuordnung eines jeden einzelnen Produkts 3 zur jeweiligen Mulde 8 durch die Steuerung 5 erfolgt. Am gezeigten Beispiel von Fig. 1a und 1b ist in der ersten Tiefziehverpackungsmaschine 6 bereits ein Produkt 3 der Sorte P2 in einer der zwei Mulden 8 des in der Einlegestation 12 bereitgestellten Formats eingelegt. Das nächstkommende Produkt 3 auf der ersten Transporteinrichtung 10 ist ein weiteres Produkt 3 der Sorte P2 und komplettiert nach dem Einlegen das Format F1. Mit einem folgenden Vorzug V des Formats F1 in einer Transportrichtung R der ersten Tiefziehverpackungsmaschine 6 innerhalb eines Arbeitstaktes wird das Format F2 bzw. die Mulde 8 für das Produkt 3 der Sorte P1 in der Einlegestation 12 zum Einlegen bereitgestellt.The products 3 are brought by the transport devices 10, 11 to insertion stations 12 of the thermoforming packaging machines 6, 7 and inserted manually or automatically into the troughs 8 provided at the insertion station 12. In this case, the wells 8 by means of forming stations 22, 23, in Fig. 2 are shown in more detail, generated, wherein the assignment of each product 3 takes place to the respective well 8 by the controller 5. On the example of Fig. 1a and 1b In the first thermoforming packaging machine 6, a product 3 of the type P2 is already placed in one of the two wells 8 of the format provided in the insertion station 12. The next product 3 on the first transport device 10 is another product 3 of the type P2 and completes the format F1 after insertion. With a following advantage V of the format F1 in a transporting direction R of the first thermoforming packaging machine 6 within one working cycle, the format F2 or the trough 8 for the product 3 of the grade P1 is provided in the insertion station 12 for insertion.

Um immer die erforderliche Anzahl von Produkten 3 der Sorten P1 bzw. P2 für ein Format an der Einlegestation 12 bereitstellen zu können, ist jeweils eine Puffereinrichtung 21 an den Transporteinrichtungen 10, 11 vorgesehen. Die Puffereinrichtung 21 kann ein oder mehrere Produkte 3 von der Transporteinrichtung 10, 11 aufnehmen, damit beispielsweise zwei zusammengehörende Produkte 3 derselben Sorte P2 aufeinanderfolgend der Einlegestation 12 zugeführt werden können. So kann sichergestellt werden, dass nicht nur ein Produkt P2, sondern, wie in diesem Beispiel gezeigt, immer direkt nacheinander zwei Produkte 3 derselben Sorte P2 dem dafür vorgesehen Format F2 zugeführt werden. Das auf der Puffereinrichtung 21 kurzzeitig zwischengelagerte Produkt P1 kann für eine Sortierung oder Gruppierung der Produkte 3 auf die Transporteinrichtungen 10, 11 zurückgeführt werden. Dies wird von der Steuerung 5 über die Steuerleitungen L veranlasst.In order to always be able to provide the required number of products 3 of the grades P1 and P2 for a format at the insertion station 12, a buffer device 21 is provided on the transport devices 10, 11 in each case. The buffer device 21 can receive one or more products 3 from the transport device 10, 11, so that, for example, two associated products 3 of the same grade P2 can be successively supplied to the insertion station 12. Thus it can be ensured that not only a product P2 but, as shown in this example, two products 3 of the same grade P2 are always fed directly to the format F2 provided for this purpose. The temporarily stored on the buffer device 21 product P1 can be attributed to a sorting or grouping of the products 3 to the transport devices 10, 11. This is caused by the controller 5 via the control lines L.

Mit weiteren Vorzügen V werden die mit Produkt 3 gefüllten Mulden 8 bzw. Formate zusammen mit einer der Übersichtlichkeit halber nur an der zweiten Verpackungsmaschine 7 dargestellten Deckelfolie D einer ersten Siegelstation 13 zugeführt. Die erste Siegelstation 13 erzeugt eine umlaufende Siegelung bzw. Rahmensiegelung 15, wobei ein Evakuieren und/oder ein Begasen des Inneren der entstehenden Verpackung 17 stattfindet. Besteht das Format F1 nur aus einer einzigen Mulde 8, so ist diese Verpackung 17 fertiggestellt. Im Falle von zwei Mulden 8 pro Format F2 wird eine noch fehlende zweite Siegelung 14a in Form einer Siegelnaht quer zur Transportrichtung R in einer zweiten Siegelstation 14 ausgeführt, um somit die Produkte P2 zu einzelnen Verpackungen 17 zu siegeln. Mittels einer Querschneidstation 18 und einer nachfolgenden Längsschneidstation 19 werden die Verpackungen aus einer Folienbahn 20, in die die Mulden 8 geformt (d.h. tiefgezogen) wurden, ausgetrennt und vereinzelt.With further advantages V, the troughs 8 or formats filled with product 3 are supplied to a first sealing station 13 together with a lidding film D shown only on the second packaging machine 7 for the sake of clarity. The first sealing station 13 generates an encircling seal or frame seal 15, wherein an evacuation and / or a gassing of the interior of the resulting packaging 17 takes place. If the format F1 only consists of a single trough 8, then this package 17 is completed. In the case of two wells 8 per format F2, a still missing second seal 14a in the form of a sealing seam transverse to the transport direction R is carried out in a second sealing station 14, thus sealing the products P2 into individual packages 17. By means of a cross-cutting station 18 and a subsequent longitudinal cutting station 19, the packages are separated from a film web 20 into which the troughs 8 have been formed (i.e., deep-drawn) and singulated.

Entsprechend den Größenunterschieden der Produkte 3 der Sorten P1 und P2 für die erste Tiefziehverpackungsmaschine 6 sind die Mulden 8 der zweiten Tiefziehverpackungsmaschine 7 zu den im Verhältnis größeren Produkten 3 der Sorten P3 und P4 größer ausgeformt, indem die Folienbreite der Folienbahn 20 größer ist und/oder der Vorzug V pro Arbeitstakt eine größere Länge als der Vorzug V der ersten Tiefziehverpackungsmaschine 6 aufweist. Der Vorzug V wird definiert durch die Länge des Formats in Transportrichtung R, die jeweils an der Tiefziehverpackungsmaschine 6, 7 in dem gezeigten Beispiel gleichbleibend ist. Beispielsweise kann der Vorzug V 400 mm an der ersten Tiefziehverpackungsmaschine 6 und 600 mm an der zweiten Tiefziehverpackungsmaschine 7 betragen.According to the size differences of the products 3 of the grades P1 and P2 for the first thermoforming packaging machine 6, the wells 8 of the second thermoforming packaging machine 7 are formed larger to the relatively larger products 3 of the grades P3 and P4 by the film width of the film web 20 is greater and / or the advantage V per working cycle has a greater length than the preference V of the first thermoforming packaging machine 6. The preference V is defined by the length of the format in the direction of transport R, which is constant on the thermoforming packaging machine 6, 7 in the example shown. For example, the merit V may be 400 mm on the first thermoforming packaging machine 6 and 600 mm on the second thermoforming packaging machine 7.

Fig. 2 zeigt die erste Tiefziehverpackungsmaschine 6, stellvertretend für beide Tiefziehverpackungsmaschinen 6, 7, in der einer Draufsicht über ihre gesamte Länge. In dieser Ansicht sind auch dargestellt eine erste Formstation 22 zum Tiefziehen von einer Mulde 8 in die Folienbahn 20 und eine zweite Formstation 23 zum Tiefziehen von zwei Mulden 8 pro Format bzw. Arbeitstakt. Die erste 22 und zweite Formstation 23 könnten ebenso miteinander vertauscht sein. Ebenso könnte die Aufteilung der zwei Mulden 8 der zweiten Formstation 23 nicht quer zur Transportrichtung R zu zwei Reihen sondern längs in Transportrichtung R zu zwei Spuren erfolgen. Entsprechend hierzu müsste die zweite Siegelstation 14 angepasst sein und anstatt einer Querschneidstation 18, die entfallen könnte, würde die Längsschneidstation 19 entsprechend die Aufteilung der zwei Verpackungen 17 bzw. Spuren mit übernehmen. Fig. 2 shows the first thermoforming packaging machine 6, representative of both thermoforming packaging machines 6, 7, in a plan view over its entire length. In this view are also shown a first forming station 22 for deep drawing of a trough 8 in the film web 20 and a second forming station 23 for deep drawing of two troughs 8 per format or power stroke. The first 22 and second forming stations 23 could also be interchanged. Likewise, the division of the two troughs 8 of the second forming station 23 could not take place transversely to the transport direction R to two rows but longitudinally in the transport direction R to two tracks. According to this, the second sealing station 14 would have to be adapted and instead of a transverse cutting station 18, which could be omitted, the longitudinal cutting station 19 would take over the division of the two packages 17 or tracks accordingly.

Figur 2 zeigt zudem noch genauer als die Figuren 1a oder 1b, wie die Deckelfolie D zugeführt wird. Insbesondere erfolgt das Zuführen der Deckelfolie D zunächst unter einem Winkel von 90° zur Transportrichtung R. Kurz vor der ersten Siegelstation 13 wird die Deckelfolie D dann an einer unter einem Winkel von 45° zur Transportrichtung R stehenden Schulter S um 90° umgelenkt. Im Anschluss an die Umlenkung an der Schulter S wird die Deckelfolie D gemeinsam mit den Mulden 8 in Transportrichtung R in die Siegelstation 13 geführt. FIG. 2 also shows more accurate than the FIGS. 1a or 1b how the cover sheet D is supplied. In particular, the cover film D is initially fed at an angle of 90 ° to the transport direction R. Shortly before the first sealing station 13, the cover film D is then deflected by 90 ° at a shoulder S which is at an angle of 45 ° to the transport direction R. Subsequent to the deflection at the shoulder S, the cover film D is guided together with the recesses 8 in the transport direction R into the sealing station 13.

Fig. 3 zeigt eine alternative Verpackungsanlage 1, die sich von den in Fig. 1a und 1b gezeigten Verpackungsanlagen 1 dadurch unterscheidet, dass nur eine einzige Tiefziehverpackungsmaschine 6 vorgesehen ist und die Produkte 3 auf drei Transporteinrichtungen 10 verteilt werden. Die Verpackungsanlage 1 ist für drei unterschiedliche Sorten von Produkten P1, P2 und P3 vorgesehen und die Verteileinrichtung 9 verteilt die Produkte 3 der Sorten P1, P2 und P3 derart auf die Transporteinrichtungen 10, so dass sich auf der jeweiligen Transporteinrichtung 10 nur ein Produkttyp, nämlich P1 oder P2 oder P3, befindet. Entsprechend den drei unterschiedlichen Typen oder Sorten P1, P2 und P3 von Produkten 3 weist die Tiefziehverpackungsmaschine 6 stromabwärts der ersten 22 und zweiten Formstation 23 eine dritte Formstation 24 auf, um vier Mulden 8 in Form von zwei hintereinander und zwei nebeneinander innerhalb des Formats angeordneten Mulden 8 in die Folienbahn 20 zu formen. Die Reihenfolge der drei Formstationen 22, 23, 24 ist beliebig wählbar. Fig. 3 shows an alternative packaging system 1, which differs from the in Fig. 1a and 1b 1, characterized in that only a single thermoforming packaging machine 6 is provided and the products 3 are distributed to three transport devices 10. The packaging installation 1 is provided for three different types of products P1, P2 and P3, and the distribution device 9 distributes the products 3 of the types P1, P2 and P3 onto the transport devices 10, so that only one product type, namely P1 or P2 or P3. Corresponding to the three different types or grades P1, P2 and P3 of products 3, the thermoforming packaging machine 6 has a third forming station 24 downstream of the first 22 and second forming stations 23, four troughs 8 in the form of two troughs arranged one behind the other and two juxtaposed within the format 8 in the film web 20 to form. The order of the three forming stations 22, 23, 24 is arbitrary.

Im Bereich der Einlegestation 12 ist jeder der drei Transporteinrichtungen 10 jeweils eine Sammeleinrichtung 25 nachgeordnet, um mehrere Produkte 3 zu puffern. An der Einlegestation 12 sind beidseitig der Tiefziehverpackungsmaschine 6 zwei Bedienpersonen 30 schematisch dargestellt, die jeweils das oder die entsprechenden Produkte 3 für das in der Einlegestation 12 befindliche Format mit ein, zwei oder vier Mulden 8 von der jeweiligen Sammeleinrichtung 25 entnehmen und in die Mulde 8 einlegen.In the region of the inserting station 12, each of the three transporting devices 10 is in each case arranged downstream of a collecting device 25 in order to buffer a plurality of products 3. At the loading station 12, the thermoforming packaging machine 6 on both sides of two operators 30 are shown schematically, each of which remove the corresponding products or 3 for the located in the loading station 12 format with one, two or four wells 8 from the respective collection device 25 and into the trough. 8 insert.

Die Tiefziehverpackungsmaschine 6 umfasst analog zu den drei Formstationen 22, 23, 24 auch eine erste 13, eine zweite 14 und zusätzlich eine dritte Siegelstation 26, um Verpackungen 17 der drei unterschiedlichen Formate herstellen zu können. In dem gezeigten Beispiel sind die erste 13 und zweite Siegelstation 14 wie in Fig. 1 und 2 ausgeführt und die dritte Siegelstation 26 zum Erzeugen einer Längssiegelung 26a in Form einer zusätzlichen Siegelnaht längs der Transportrichtung R konfiguriert. Des Weiteren umfasst die Tiefziehverpackungsmaschine 6 eine Querschneidstation 18 und eine Längsschneidstation 19, wobei die Längsschneidstation 19 dazu konfiguriert ist, wahlweise eine Schneidung mittig im Format in der Siegelnaht 26a, die in der dritten Siegelstation 26 erzeugt wurde, auszuführen.The thermoforming packaging machine 6 comprises, analogously to the three forming stations 22, 23, 24, also a first 13, a second 14 and additionally a third sealing station 26 in order to be able to produce packaging 17 of the three different formats. In the example shown, the first 13 and second sealing stations 14 are as in FIG Fig. 1 and 2 configured and the third sealing station 26 configured to produce a longitudinal seal 26a in the form of an additional sealing seam along the transport direction R. Further, the thermoforming packaging machine 6 includes a cross cutting station 18 and a longitudinal cutting station 19, wherein the longitudinal cutting station 19 is configured to selectively perform a cut centrally in the format in the seal 26a produced in the third sealing station 26.

Auf der Zuführeinrichtung 2 ist analog zur Verpackungsanlage 1 aus Fig. 1a oder 1b die Prüfstation 4 vorgesehen, um die Position und Produktmerkmale der jeweiligen Produkte 3 zu ermitteln und anschließend die Produkte 3 gemäß ihren Produktmerkmalen mittels einer oder mehrerer Pusher 27 der Verteileinrichtung 9 auf die jeweiligen Transporteinrichtungen 10 zu verteilen bzw. zu übergeben.On the feeder 2 is analogous to the packaging system 1 from Fig. 1a or 1b the test station 4 is provided to determine the position and product characteristics of the respective products 3 and then the products 3 according to their product features by means of one or more Pusher 27 of the distributor 9 to distribute to the respective transport devices 10 or to pass.
