Definitions

  • the invention is based on a device and a method for aligning packaging according to the species of the independent claims. From the DE 198 27 059A1 a device for filling, evacuating and sealing packages is already known.
  • An additional conveyor includes evacuation chambers and a folding and sealing station. The packaging containers are placed in the evacuation chambers without pre-folding the top area, so that the full cross-section of the pack is available for evacuation.
  • the device comprises at least one gripping device, with means for creating a predetermined breaking point being provided on the container. After the predetermined breaking point has been produced, the gripping device grasps a gripping surface delimited by the predetermined breaking point in order to remove the covering film from the container.
  • a clamping device clamps a first partial area of the sterile packaging.
  • a cutting device creates a slit in the sterile packaging, while a removal device removes the object from the sterile packaging through the slit.
  • a device for evacuating and gassing filled packages is already known.
  • a chamber which receives the pack and is connected to a vacuum source is provided.
  • a mouthpiece with openings for the supply of protective gas up to the cross-section of the opening is provided above the packing in the chamber.
  • the openings in the mouthpiece are in the form of slots and are arranged parallel to one another and at right angles to the opening cross-section of the pack.
  • the object of the invention is to align packaging surrounding a container in a simple manner in such a way that the packaging can be opened easily. This object is solved by the features of the independent claims.
  • the device according to the invention and the method according to the invention for aligning packaging according to the features of the independent claims have the advantage that a folded packaging flap is aligned in a simple manner for the purpose of later mechanical opening of the packaging. Unfolding or aligning by hand can be omitted. This is made possible by placing a package surrounding a container in a vacuum chamber. The vacuum chamber is then evacuated. This creates a negative pressure around the package, causing the gas within the package to expand and a folded flap of the package to fold out so that the package aligns itself.
  • At least one fixing means is also provided, which holds the aligned packaging in the desired position. In particular, this prevents the erected packaging from collapsing after the pressure conditions have changed and allows the packaging to then be opened safely.
  • the fixing means comprises at least one clamping plate, preferably at least two clamping plates.
  • the generally rectangular packaging can be prevented from receding over the entire length on the side to be cut open later.
  • the elements of the fixing means such as the clamping plates or rollers, are particularly preferably movable relative to one another. This facilitates targeted fixing and tightening after the packaging has been aligned.
  • the gas in the packaging is also evacuated.
  • the inflated packaging is flattened again, but without giving up the desired position of the unfolded packaging again.
  • ventilation and/or disinfection of the vacuum chamber is provided. This ventilation of the vacuum chamber can preferably take place via filtered air.
  • a disinfectant can be introduced into the ventilation line via an atomizer. As a result, the sterility required in particular for pharmaceutical applications is achieved.

  • the vacuum chamber 32 has a slidable inlet 28 which is open for feeding the container 12 to the interior of the vacuum chamber 32.
  • the vacuum chamber 32 is delimited by an outlet 30, which can also be opened, so that the container 12 with the packaging 10 then aligned can leave the interior of the vacuum chamber 32.
  • a vacuum port 24 is provided on a side wall of the vacuum chamber 32 to draw a vacuum inside the vacuum chamber 32 .
  • a ventilation connection 26 is arranged on the upper side of the vacuum chamber 32 .

Die Erfindung geht aus von einer Vorrichtung und einem Verfahren zum Ausrichten von Verpackungen nach der Gattung der unabhängigen Ansprüche. Aus der DE 198 27 059A1 ist bereits eine Vorrichtung zum Füllen, Evakuieren und Verschließen von Verpackungen bekannt. Eine zusätzliche Fördereinrichtung umfasst Evakuierkammern und eine Falt- und Siegelstation. Die Verpackungsbehälter werden in die Evakuierkammern eingebracht, ohne deren Kopfbereich vorzufalten, sodass dort der volle Packungsquerschnitt zum Evakuieren zur Verfügung steht.The invention is based on a device and a method for aligning packaging according to the species of the independent claims. From the DE 198 27 059A1 a device for filling, evacuating and sealing packages is already known. An additional conveyor includes evacuation chambers and a folding and sealing station. The packaging containers are placed in the evacuation chambers without pre-folding the top area, so that the full cross-section of the pack is available for evacuation.

Aus der DE 10 2006 005 700 A1 sind eine Vorrichtung und ein Verfahren zum Entfernen einer Abdeckfolie von einem Behälter bekannt. Die Vorrichtung umfasst zumindest eine Greifvorrichtung, wobei Mittel zum Erzeugen einer Sollbruchstelle am Behälter vorgesehen sind. Die Greifvorrichtung greift nach Erzeugen der Sollbruchstelle eine von der Sollbruchstelle begrenzte Greiffläche zum Entfernen der Abdeckfolie von dem Behälter.From the DE 10 2006 005 700 A1 a device and a method for removing a cover film from a container are known. The device comprises at least one gripping device, with means for creating a predetermined breaking point being provided on the container. After the predetermined breaking point has been produced, the gripping device grasps a gripping surface delimited by the predetermined breaking point in order to remove the covering film from the container.

Aus der DE 10 2007 027 878 sind eine Vorrichtung und ein Verfahren zum Entnehmen eines sterilen Gegenstands aus einer Sterilverpackung bekannt. Hierzu klemmt eine Klemmeinrichtung einen ersten Teilbereich der Sterilverpackung. Eine Schneidvorrichtung erzeugt einen Schlitz in der Sterilverpackung, während eine Entnahmeeinrichtung den Gegenstand durch den Schlitz aus der Sterilverpackung entnimmt.From the DE 10 2007 027 878 a device and a method for removing a sterile object from a sterile packaging are known. For this purpose, a clamping device clamps a first partial area of the sterile packaging. A cutting device creates a slit in the sterile packaging, while a removal device removes the object from the sterile packaging through the slit.

Aus der DE 29619 396 U1 ist bereits eine Vorrichtung zum Evakuieren und Begasen von gefüllten Packungen bekannt. Hierzu ist eine die Packung aufnehmende mit einer Unterdruckquelle verbundene Kammer vorgesehen. Über der Packung in der Kammer ist ein Mundstück mit Öffnungen für die Zuleitung von Schutzgas bis an den Öffnungsquerschnitt vorgesehen. Die Öffnungen im Mundstück sind als Schlitze ausgebildet und parallel zueinander und rechtwinklig zum Öffnungsquerschnitt der Packung angeordnet.From the DE 29619 396 U1 a device for evacuating and gassing filled packages is already known. For this purpose, a chamber which receives the pack and is connected to a vacuum source is provided. A mouthpiece with openings for the supply of protective gas up to the cross-section of the opening is provided above the packing in the chamber. The openings in the mouthpiece are in the form of slots and are arranged parallel to one another and at right angles to the opening cross-section of the pack.

Der Erfindung liegt die Aufgabe zugrunde, eine einen Behälter umgebende Verpackung in einfacher Weise so auszurichten, dass die Verpackung leicht geöffnet werden kann. Diese Aufgabe wird gelöst durch die Merkmale der unabhängigen Ansprüche.The object of the invention is to align packaging surrounding a container in a simple manner in such a way that the packaging can be opened easily. This object is solved by the features of the independent claims.

Vorteile der ErfindungAdvantages of the Invention

Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren zum Ausrichten von Verpackungen gemäß den Merkmalen der unabhängigen Ansprüche haben demgegenüber den Vorteil, dass eine eingefaltete Verpackungslasche in einfacher Art und Weise ausgerichtet wird zum Zwecke des späteren maschinellen Öffnens der Verpackung. Ein Ausfalten bzw. Ausrichten von Hand kann entfallen. Dies wird dadurch ermöglicht, dass eine einen Behälter umgebende Verpackung in eine Vakuumkammer gebracht wird. Anschließend wird die Vakuumkammer evakuiert. Dadurch wird ein Unterdruck in der Umgebung der Verpackung erzeugt, sodass sich das Gas in der Verpackung ausdehnt und eine eingefaltete Lasche der Verpackung sich ausfaltet, so dass sich die Verpackung ausrichtet.The device according to the invention and the method according to the invention for aligning packaging according to the features of the independent claims have the advantage that a folded packaging flap is aligned in a simple manner for the purpose of later mechanical opening of the packaging. Unfolding or aligning by hand can be omitted. This is made possible by placing a package surrounding a container in a vacuum chamber. The vacuum chamber is then evacuated. This creates a negative pressure around the package, causing the gas within the package to expand and a folded flap of the package to fold out so that the package aligns itself.

Weiter ist zumindest ein Fixiermittel vorgesehen, welches die ausgerichtete Verpackung in der gewünschten Position hält. Dadurch wird insbesondere ein Einklappen der aufgerichteten Verpackung nach Änderung der Druckverhältnisse unterbunden und ein anschließendes sicheres Öffnen der Verpackung ermöglicht.At least one fixing means is also provided, which holds the aligned packaging in the desired position. In particular, this prevents the erected packaging from collapsing after the pressure conditions have changed and allows the packaging to then be opened safely.

In einer zweckmäßigen Weiterbildung umfasst das Fixiermittel zumindest ein Klemmblech, bevorzugt zumindest zwei Klemmbleche. Damit kann ein Zurückweichen der in der Regel rechteckförmigen Verpackung auf der später aufzuschneidenden Seite über die ganze Länge hinweg vermieden werden. Besonders bevorzugt sind die Elemente des Fixiermittels wie beispielsweise die Klemmbleche oder Rollen relativ zu einander bewegbar. Damit wird ein gezieltes Fixieren und Straffen nach Ausrichten der Verpackung erleichtert.In an expedient development, the fixing means comprises at least one clamping plate, preferably at least two clamping plates. In this way, the generally rectangular packaging can be prevented from receding over the entire length on the side to be cut open later. The elements of the fixing means, such as the clamping plates or rollers, are particularly preferably movable relative to one another. This facilitates targeted fixing and tightening after the packaging has been aligned.

In einer zweckmäßigen Weiterbildung ist vorgesehen, dass nach dem Evakuieren der Evakuierkammer auch das Gas in der Verpackung evakuiert wird. Dadurch wird die aufgeblähte Verpackung wieder abgeflacht, ohne jedoch die gewünschte Position der ausgefalteten Verpackung wieder aufzugeben. In einer zweckmäßigen Weiterbildung ist eine Belüftung und/oder Desinfizierung der Vakuumkammer vorgesehen. Diese Belüftung der Vakuumkammer kann vorzugsweise über gefilterte Luft erfolgen. Über einen Zerstäuber kann ein Desinfektionsmittel in die Belüftungsleitung eingeleitet werden. Dadurch wird die Keimfreiheit, wie sie insbesondere für pharmazeutische Anwendungen erforderlich ist, erreicht.In an expedient development, it is provided that after the evacuation of the evacuation chamber, the gas in the packaging is also evacuated. As a result, the inflated packaging is flattened again, but without giving up the desired position of the unfolded packaging again. In an expedient development, ventilation and/or disinfection of the vacuum chamber is provided. This ventilation of the vacuum chamber can preferably take place via filtered air. A disinfectant can be introduced into the ventilation line via an atomizer. As a result, the sterility required in particular for pharmaceutical applications is achieved.

Weitere zweckmäßige Weiterbildungen ergeben sich aus weiteren abhängigen Ansprüchen und aus der Beschreibung.Further expedient developments result from further dependent claims and from the description.

Zeichnungdrawing

Ein Ausführungsbeispiel von Vorrichtung und Verfahren zum Ausrichten von Verpackungen ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben.An exemplary embodiment of the device and method for aligning packaging is shown in the drawing and is described in more detail below.

Es zeigen:

  • die Figur 1 eine perspektivische Ansicht der Vorrichtung zum Ausrichten von Verpackungen sowie
  • die Figur 2 eine Draufsicht auf die Vorrichtung mit noch weiteren Komponenten.
Show it:
  • the figure 1 a perspective view of the device for aligning packages and
  • the figure 2 a plan view of the device with further components.

Eine Vorrichtung 8 zum Ausrichten von Verpackungen 10 umfasst mehrere Komponenten. Eine Zuführung 20 transportiert einen von der Verpackung 10 umgebenen Behälter 12. Die Oberseite des Behälters 12 ist wiederum mit einer Abdeckfolie 14 verschlossen. Im Inneren des Behälters 12 können beispielsweise zu befüllende Behältnisse wie Vials oder vorsterilisierte Spritzen angeordnet sein, die in dem Behälter 12 beispielsweise zur Abfüllung mit Pharmazeutika angeliefert werden. Die Verpackung 10 weist zumindest einen eingefalteten Bereich auf wie beispielsweise eine Laschenecke 16, die - exemplarisch in der Figur 1 dargestellt - so eingefaltet ist, dass sich eine rechteckförmige Außenkontur bildet.A device 8 for aligning packages 10 comprises several components. A feeder 20 transports one surrounded by the package 10 Container 12. The top of the container 12 is in turn closed with a cover film 14. Inside the container 12, for example, containers to be filled, such as vials or pre-sterilized syringes, can be arranged, which are delivered in the container 12, for example for filling with pharmaceuticals. The packaging 10 has at least one folded area, such as a flap corner 16, which - as an example in the figure 1 shown - is folded in such a way that a rectangular outer contour is formed.

Die Zuführung 20 befördert den von der Verpackung 10 umgebenen Behälter 12 in eine Vakuumkammer 32. Die Vakuumkammer 32 weist einen verschiebbaren Einlass 28 auf, der zur Zuführung des Behälters 12 zum Inneren der Vakuumkammer 32 geöffnet ist. Auf der anderen Seite wird die Vakuumkammer 32 begrenzt durch einen Auslass 30, der ebenfalls geöffnet werden kann, sodass der Behälter 12 mit dann ausgerichteter Verpackung 10 das Innere der Vakuumkammer 32 verlassen kann. An einer Seitenwand der Vakuumkammer 32 ist ein Vakuumanschluss 24 vorgesehen, um im Inneren der Vakuumkammer 32 ein Vakuum anzulegen. An der Oberseite der Vakuumkammer 32 ist ein Belüftungsanschluss 26 angeordnet. Im Inneren der Vakuumkammer 32 ist zumindest ein Fixiermittel 22 vorgesehen. Dessen Außenkanten verlaufen vorzugsweise parallel zur Transportrichtung des Behälters 12. Das Fixiermittel 22 besteht vorzugsweise aus zwei Klemmblechen, die senkrecht zur Transportrichtung auf- und abwärts bewegt werden können. Diese sollen dazu dienen, eine ausgerichtete Verpackung 10 im ausgerichteten Zustand zu belassen. Das Fixiermittels Wirkt auch außerhalb der Vakuumkammer 32, um auch außerhalb der Vakuumkammer 32 die Verpackung 10 im ausgerichteten Zustand zu belassen. Im Inneren der Vakuumkammer 32 befindet sich ein von der Zuführung 20 entkoppeltes Transportmittel, das den im Inneren der Vakuumkammer 32 befindlichen Behälter 12 überden geöffneten Auslass 30 an eine Abführung 21 abgibt, die den Weitertransport des Behälters 12 übernimmt.The feeder 20 conveys the container 12 surrounded by the package 10 into a vacuum chamber 32. The vacuum chamber 32 has a slidable inlet 28 which is open for feeding the container 12 to the interior of the vacuum chamber 32. On the other side, the vacuum chamber 32 is delimited by an outlet 30, which can also be opened, so that the container 12 with the packaging 10 then aligned can leave the interior of the vacuum chamber 32. A vacuum port 24 is provided on a side wall of the vacuum chamber 32 to draw a vacuum inside the vacuum chamber 32 . A ventilation connection 26 is arranged on the upper side of the vacuum chamber 32 . At least one fixing means 22 is provided inside the vacuum chamber 32 . Its outer edges preferably run parallel to the transport direction of the container 12. The fixing means 22 preferably consists of two clamping plates which can be moved up and down perpendicularly to the transport direction. These are intended to keep an aligned package 10 in the aligned condition. The fixing agent also acts outside of the vacuum chamber 32 in order to leave the packaging 10 in the aligned state outside of the vacuum chamber 32 as well. Inside the vacuum chamber 32 there is a transport means which is decoupled from the feed 20 and delivers the container 12 located inside the vacuum chamber 32 via the opened outlet 30 to a discharge 21 which transports the container 12 further.

Bei der Ansicht gemäß Figur 2 lässt sich wiederum die Zuführung 20 entnehmen, die den mit der Verpackung 10 versehenen Behälter 12 mit eingefalteter Lasche 16 in das Innere der Vakuumkammer 32 transportiert. Zum Anlegen eines Vakuums in der Vakuumkammer 32 ist eine Vakuumpumpe 34 mit Ventil 35 und entsprechender Regelung 36 vorgesehen, wobei ein Vakuumrezipient 37 das aus der Vakuumkammer 32 evakuierte Gas wie beispielsweise Luft aufnimmt. Im Inneren der Vakuumkammer 32 wird die Verpackung 10 ausgerichtet, indem durch Anlegen eines Vakuums die eingefaltete Laschenecke 16 in eine ausgerichtete Laschenecke 18 übergeführt wird. Die so ausgerichtete Verpackung 10 wird durch das Fixiermittel 22 in dieser Position gehalten und aus dem Inneren der Vakuumkammer 32 mittels Transportmittel 23 und Abführung 21 einer optionalen Beutelöffnungsvorrichtung 40 zugeführt. Diese öffnet die Verpackung 10 an der ausgerichteten Verpackungsseite beispielsweise durch seitliches Aufschneiden der Verpackung 10.According to the view figure 2 In turn, the feeder 20 can be removed, which transports the container 12 provided with the packaging 10 with the flap 16 folded in, into the interior of the vacuum chamber 32 . To create a vacuum in the vacuum chamber 32, a vacuum pump 34 with a valve 35 and corresponding control 36 is provided, with a vacuum recipient 37 receiving the gas evacuated from the vacuum chamber 32, such as air. Inside the vacuum chamber 32, the package 10 is aligned by converting the folded-in tab corner 16 into an aligned tab corner 18 by applying a vacuum. The packaging 10 aligned in this way is held in this position by the fixing means 22 and fed from inside the vacuum chamber 32 by means of transport means 23 and discharge 21 to an optional bag opening device 40 . This opens the packaging 10 on the aligned packaging side, for example by cutting open the packaging 10 at the side.

Die beschriebene Vorrichtung 8 zum Ausrichten von Verpackungen 10 arbeitet folgendermaßen. Der Behälter 12 wird mit der ihn umgebenden, noch nicht ausgerichteten Verpackung 10 in das Innere der Vakuumkammer 32 gebracht. An derVakuumkammer32 werden nun Einlass 28 und Auslass 30 geschlossen. Die Vakuumkammer 32 wird nun evakuiert mittels Vakuumpumpe 34 und Vakuumrezipient 37. Hierzu ist die Vakuumpumpe 34 über eine nicht dargestellte Leitung über den Vakuumanschluss 24 mit der Vakuumkammer 32 verbunden. Das Gas in der Verpackung 10 befindet sich nach dem Evakuieren in einer Unterdruckumgebung. Dadurch dehnt sich das Gas in der Verpackung 10 aus und bläht diese auf. Die zur Behältermitte hin eingefaltete Lasche 16 bewegt sich dadurch von der Behältermitte weg und steht nach Außen ab. In diesem Zustand ist die Verpackung 10 ausgerichtet, das heißt, die Außenkonturen der Verpackung 10 befinden sich in einem Zustand, der ein beinahe maximales Volumen der Verpackung 10 ermöglicht. Insbesondere die Seitenkanten der Verpackung 10 sind nun soweit als möglich vom Behälter 10 entfernt, was ein Öffnen der Verpackung 10 ohne Beschädigung des Behälters 12 erleichtert.The device 8 described for aligning packages 10 operates as follows. The container 12 is placed inside the vacuum chamber 32 with the package 10 surrounding it, not yet aligned. At the vacuum chamber 32, inlet 28 and outlet 30 are now closed. The vacuum chamber 32 is now evacuated by means of the vacuum pump 34 and the vacuum recipient 37. For this purpose, the vacuum pump 34 is connected to the vacuum chamber 32 via a line (not shown) via the vacuum connection 24. The gas in package 10 is in a negative pressure environment after evacuation. As a result, the gas in the package 10 expands and inflates it. The tab 16 folded in towards the center of the container thereby moves away from the center of the container and protrudes outwards. In this state, the packaging 10 is aligned, that is, the outer contours of the packaging 10 are in a state that allows the packaging 10 to have an almost maximum volume. In particular, the side edges of the packaging 10 are now as far away from the container 10 as possible, which makes it easier to open the packaging 10 without damaging the container 12 .

Die so ausgerichtete Verpackung 10 mit ausgerichteter Lasche 18 wird über das Fixiermittel 22 an einem Zurückweichen aus dem ausgerichteten Zustand gehindert. Denn insbesondere beim Belüften der Vakuumkammer 32 würde sich sonst die Außenkante der Verpackung 10 in Richtung des Behälters 12 zurückbewegen. Als Fixiermittel 22 könnten ein oder mehrere Klemmbleche verwendet sein, welche auf- und abbewegbar ausgebildet sind. Lage und Geometrie der Fixiermittel 22 sind jedenfalls so gewählt, dass diese zumindest einen Seitenbereich oder eine Seitenkante der ausgerichteten Verpackung 10 sicher mechanisch klemmen oder greifen und straffen. Auch eine andere Realisierung des Fixiermittels 22 wäre möglich wie beispielsweise in Form von Greifer, Luftansaugung oder ähnliches. Jedenfalls muss eine gewisse Kraft auf die Verpackung 10 ausgeübt werden, um ein Zurückweichen zu verhindern und die Verpackung 10 zu straffen. Die Straffung der Lasche 16 bzw. der Verpackung könnte auch über angetriebene Rollen im Klemmblech (als Beispiel eines Fixiermittels 22) erfolgen.The packaging 10 aligned in this way with the flap 18 aligned is prevented from receding from the aligned state via the fixing means 22 . Otherwise, particularly when the vacuum chamber 32 is vented, the outer edge of the packaging 10 would move back in the direction of the container 12 . One or more clamping plates could be used as fixing means 22, which are designed to be movable up and down. In any case, the position and geometry of the fixing means 22 are selected in such a way that they securely mechanically clamp or grip and tighten at least one side area or one side edge of the aligned packaging 10 . Another implementation of the fixing means 22 would also be possible, for example in the form of a gripper, air intake or the like. In any event, some force must be applied to the package 10 to prevent backing off and to tighten the package 10. The strap 16 or the packaging could also be tightened via driven rollers in the clamping plate (as an example of a fixing means 22).

Die Verpackung 10 besteht häufig zumindest teilweise aus einem Gas-, aber nicht Wasser-durchlässigem Stoff, der als Filter, vorzugsweise als Sterilfilter wirkt. Hierfür eignet sich beispielsweise ein Vlies. In der Regel ist die Verpackung 10 nicht luftdicht verschlossen, so dass auch die Verpackung 10 evakuiert werden könnte, was jedoch nur so wenig wie möglich erfolgen sollte. Hierzu wird besonders bevorzugt in derVakuumkammer 32 ein kurzes, stoßartiges Vakuum für die Dauer von ca. 1-2 s angelegt. Die Siegelnähte der Verpackung 10 sind so auszulegen, dass sie diesem Druckstoß widerstehen.The packaging 10 often consists, at least in part, of a material which is permeable to gas but not water and which acts as a filter, preferably as a sterile filter. A fleece is suitable for this, for example. As a rule, the packaging 10 is not hermetically sealed, so that the packaging 10 could also be evacuated, but this should only be done as little as possible. For this purpose, a short, sudden vacuum is particularly preferably applied in the vacuum chamber 32 for a period of approx. 1-2 s. The sealing seams of the packaging 10 are to be designed in such a way that they withstand this pressure surge.

Nach dem Ausrichten der Verpackung 10 mit nun ausgefalteter Lasche 18 wird die Vakuumkammer 32 wieder belüftet. Über den Belüftungsanschluss 26 wird Luft zugeführt, die unter Umständen vorher gefiltert wurde. Über einen nicht eigens dargestellten Zerstäuber könnte auch ein Desinfektionsmittel in die Belüftungsleitung, die an den Belüftungsanschluss 26 angeschlossen ist, eingeleitet werden. Eine Desinfektion könnte jedoch auch in einer von der Vakuumkammer32 separaten Desinfektionskammer erfolgen.After aligning the package 10 with With the flap 18 now folded out, the vacuum chamber 32 is vented again. Air, which may have been previously filtered, is supplied via the ventilation connection 26 . A disinfectant could also be introduced into the ventilation line, which is connected to the ventilation connection 26, via an atomizer that is not specifically shown. However, disinfection could also take place in a disinfection chamber separate from the vacuum chamber32.

Die Fixiermittel 22 öffnen sich einen Spalt und geben die ausgefaltete Lasche 18 und somit die gesamte ausgerichtete Verpackung 10 zum Weitertransport aus der Vakuumkammer 32 frei. Nach dem Belüften der Vakuumkammer 32 öffnen sich Einlass 28 und Auslass 30. Die ausgerichtete Verpackung 10 wird aus der Vakuumkammer 32 durch die Transportmittel 22 und die Abführung 21 abtransportiert.The fixing means 22 open a gap and release the folded-out flap 18 and thus the entire aligned packaging 10 for further transport out of the vacuum chamber 32 . After the vacuum chamber 32 has been vented, the inlet 28 and outlet 30 open.

Auch außerhalb der Vakuumkammer 32 sind Fixiermittel 22 angeordnet, die verhindern, dass die ausgefaltete Laschenecke 18 sich wieder einfaltet. Hierzu können ein oder zwei Bleche, deren Seitenkanten parallel zur Transportrichtung ausgerichtet sind, vorgesehen werden. Dadurch wird sichergestellt, dass die ausgerichtete Verpackung 10 in diesem Zustand verbleibt, bis sie geöffnet wird. Gegebenenfalls können vor Erreichen der Verpackungsöffnungsvorrichtung 40 noch weitere Stationen durchlaufen werden. So könnte die Verpackung 10 in einer separaten Desinfektionskammer desinfiziert und anschließend in einer Trocknungsstrecke wieder getrocknet werden. Auch für diese weiteren Bearbeitungsschritte stellen geeignet angeordnete Fixiermittel 22 sicher, dass die Verpackung 10 im ausgerichteten Zustand verbleibt.Fixing means 22 are also arranged outside of the vacuum chamber 32 and prevent the flap corner 18 that has been folded out from folding in again. For this purpose, one or two metal sheets can be provided, the side edges of which are aligned parallel to the transport direction. This ensures that the aligned package 10 remains in this condition until opened. If necessary, further stations can be passed through before the package opening device 40 is reached. The packaging 10 could be disinfected in a separate disinfection chamber and then dried again in a drying section. For these further processing steps, too, suitably arranged fixing means 22 ensure that the packaging 10 remains in the aligned state.

Die ausgerichteten Verpackungen 10 werden nun beispielsweise einer Verpackungsöffnungsvorrichtung 40 zugeführt. Dort wird die ausgefaltete Laschenecke 18 bzw. die ausgerichtete Verpackung 10 aufgeschnitten, so dass der Behälter 12 der Verpackung 10 entnommen werden kann. Anschließend wird die Abdeckfolie 14 entfernt, so dass die in dem Behälter 12 befindlichen Behältnisse wie beispielsweise Vials, Spritzenbehältnisse oder ähnliches entnommen und der Weiterverarbeitung zugeführt werden können. Diese Behältnisse können beispielsweise in einer Füll- und Verschließeinrichtung mit Pharmazeutika befüllt werden. Diese Behältnisse wie Einwegspritzen werden vorsterilisiert in dem Behälter 12 (Box, Tub) in einer Verpackung 10 verpackt angeliefert. Durch die beschriebene Vorrichtung zum Ausrichten von Verpackungen 10 können die Verpackungen 10 in einer vordefinierten und für das Öffnen der Verpackung 10 günstigen Lage der Verpackungsöffnungsvorrichtung 40 zugeführt werden. Damit erübrigt sich insbesondere eine manuelle Ausrichtung, so dass die Verpackung 10 ohne manuelle Vorarbeit geöffnet werden kann.The aligned packages 10 are now fed to a package opening device 40, for example. The folded-out tab corner 18 or the aligned packaging 10 is cut open there, so that the container 12 can be removed from the packaging 10 . The cover film 14 is then removed so that the containers located in the container 12, such as vials, syringe containers or the like, can be removed and fed to further processing. These containers can be filled with pharmaceuticals, for example, in a filling and closing device. These containers, such as disposable syringes, are delivered pre-sterilized in the container 12 (box, tub) in a packaging 10 . The device for aligning packages 10 described allows the packages 10 to be fed to the package opening device 40 in a predefined position that is favorable for opening the package 10 . In particular, manual alignment is thus unnecessary, so that the packaging 10 can be opened without manual preparatory work.
