Description

Die Erfindung geht aus von einer Vorrichtung zum Sterilisieren von Verpackungsbehältern nach der Gattung des Oberbegriffs des Anspruchs 1. Bei der Trockenhitzesterilisation von Behältern, beispielsweise Glasflaschen, Ampullen o. dgl. für parenterale Arzneimittel ist es von äußerster Wichtigkeit, daß alle in der Sterilisationsvorrichtung behandelten Behälter auf eine bestimmte Solltemperatur erhitzt werden. Zum Überwachen der Sterilisationstemperatur ist es bei einer aus der EP-A-312 022 bekannten Sterilisiervorrichtung bekannt, mit einem Strahlungspyrometer die Temperatur der Behälter in der Sterilisierzone zu messen und danach die Förderung der Behälter durch den Ofen zu beeinflussen. Um das Pyrometer vor großer Hitzeeinwirkung zu schützen und um eine unbehinderte Sicht auf ein relativ großes Feld zu gewährleisten, ist das Pyrometer in einer Seitenwand des Ofens eingebaut, so daß die Behälter in einem Prüffeld quer zu ihrer Förderrichtung in einem relativ flachen Winkel von oben erfaßt werden. Da die Behälter durch den Ofen in der Regel Seite an Seite aneinander anliegend geführt werden, ist von ihnen jeweils nur ihr oberer Bereich einer Temperaturüberprüfung zugänglich. Bei dieser Überprüfung wird davon ausgegangen, daß die oberen Bereiche der Behälter im erfaßten Feld insgesamt einen repräsentativen Meßwert liefern. Bei der bekannten Vorrichtung ist jedoch nicht sichergestellt, daß auch ihr Körper und ihr Boden die für die Sterilisation erforderliche Mindesttemperatur erreicht haben.The invention is based on a device for sterilizing packaging containers according to the preamble of claim 1. In the dry heat sterilization of containers, for example glass bottles, ampoules or the like for parenteral drugs, it is of the utmost importance that all containers treated in the sterilization device are heated to a certain target temperature. To monitor the sterilization temperature it is known in a sterilization device known from EP-A-312 022 to measure the temperature of the containers in the sterilization zone with a radiation pyrometer and then to influence the conveyance of the containers through the oven. In order to protect the pyrometer from excessive heat and to ensure an unobstructed view of a relatively large field, the pyrometer is installed in a side wall of the furnace, so that the containers are gripped in a test field transverse to their conveying direction at a relatively flat angle from above become. Since the containers are usually guided side by side through the furnace, only their upper area is a temperature check of them accessible. This check assumes that the upper areas of the containers in the field covered provide a representative measured value overall. In the known device, however, it is not ensured that her body and floor have reached the minimum temperature required for sterilization.

Vorteile der ErfindungAdvantages of the invention

Die Sterilisiervorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, daß sehr repräsentative Bereiche der Behälter, nämlich der Öffnungsrand, die Schulter und insbesondere der Boden durch die Öffnung des Behälters auf die erreichten Temperaturen überwacht werden. Insbesondere ist das Erfassen der Temperatur der Innenseite des Bodens wichtig, da durch Verdunsten von Flüssigkeitsresten, die gegebenfalls vom vorausgehenden Waschen zurückgeblieben sind, nicht die Solltemperatur erreicht wird.The sterilizing device with the characterizing features of claim 1 has the advantage that very representative areas of the container, namely the opening edge, the shoulder and in particular the bottom are monitored by the opening of the container for the temperatures reached. In particular, it is important to measure the temperature of the inside of the floor, since evaporation of liquid residues, which may have remained from the previous washing, does not achieve the desired temperature.

Durch die in den Unteransprüchen ausgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Sterilisiervorrichtung möglich. Eine besonders vorteilhafte Ausführung ergibt sich durch das Kennzeichen nach Anspruch 3, wonach alle durch den Ofen geförderten Behälter einer Temperaturüberwachung zugänglich gemacht werden. Darüberhinaus ist die Anordnung mehrerer Spiegel nach Anspruch 2 vorteilhaft, so daß bei Einbauten im Ofen die Behälter in Deckung zu den Zwischenräumen zwischen den Einbauten erfaßt werden.Advantageous further developments and improvements of the sterilizing device specified in claim 1 are possible through the measures set out in the subclaims. A particularly advantageous embodiment results from the characterizing feature according to claim 3, according to which all containers conveyed through the furnace are made accessible to temperature monitoring. In addition, the arrangement of several mirrors according to claim 2 is advantageous, so that when installed in the oven, the containers are covered to cover the spaces between the internals.

Ein Wärmebild mit punktueller Auswertemöglichkeit ergibt sich durch die Ausgestaltung nach Anspruch 4.A thermal image with selective evaluation results from the configuration according to claim 4.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen Figur 1 einen Aufheiz- und Sterilisierofen einer Sterilisiervorrichtung vereinfacht im Längsschnitt und Figur 2 den Sterilisierofen nach Figur 1 im Querschnitt.An embodiment of the invention is shown in the drawing and will be described in more detail below. 1 shows a heating and sterilizing oven of a sterilizing device simplified in longitudinal section and FIG. 2 shows the sterilizing oven according to FIG. 1 in cross section.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Die Aufheiz- und Sterilisierzone einer Trockenhitzesterilisiervorrichtung hat einen tunnelartigen Ofen 10 mit einer Decke 11, einem Boden 12, einer Vorderwand 13, einer Rückwand 14 und zwei Seitenwanden 15 und 16 aus warmeisolierendem Material. Zum Durchführen der zu sterilisierenden Behälter 1 erstreckt sich ein waagrechtes Trum eines hitzefesten, endlosen Transportbandes 17 durch den Ofen 10, das durch einen Durchbruch 18 in der Vorderwand 13 in den Ofen einläuft und durch einen Durchbruch 19 aus dem Ofen 10 wieder austritt. Oberhalb und unterhalb der Transportstrecke des Transportbandes 17 sind Heizelemente, vorzugsweise stabförmige IR-Strahler 21, 22 mit Reflektoren in gleichen Abständen quer zur Förderrichtung angeordnet, durch deren IR-Strahlung und die sich im Ofen 10 einstellende Konvektion die mit dem Transportband 17 durch den Ofen 10 geförderten Behälter 1, wie Flaschen, Ampullen u. dgl. aus Glas auf eine Mindest-Sterilisationstemperatur, beispielsweise im Bereich von 350° C erhitzt werden. Alternativ oder zusätzlich kann der Ofen auch mit Heißluft im Larninarflow-Verfahren betrieben werden.The heating and sterilizing zone of a dry heat sterilizing device has a tunnel-like oven 10 with a ceiling 11, a bottom 12, a front wall 13, a rear wall 14 and two side walls 15 and 16 made of heat-insulating material. To carry out the container 1 to be sterilized, a horizontal run of a heat-resistant, endless conveyor belt 17 extends through the furnace 10, which enters the furnace through an opening 18 in the front wall 13 and exits the furnace 10 again through an opening 19. Above and below the transport path of the conveyor belt 17, heating elements, preferably rod-shaped IR radiators 21, 22 with reflectors are arranged at equal intervals transversely to the conveying direction, due to their IR radiation and the convection occurring in the oven 10, that with the conveyor belt 17 through the oven 10 conveyed containers 1, such as bottles, ampoules and the like. Like. Be heated from glass to a minimum sterilization temperature, for example in the range of 350 ° C. Alternatively or additionally, the furnace can also be operated with hot air using the Larninarflow process.

Zum Überprüfen, ob die durch den Ofen 10 geförderten Behälter 1 auf die notwendige Sterilisationstemperatur erwärmt werden, ist oberhalb des Durchbruchs 18 in der Vorderwand 13 ein Wärmestrahlungsmeßgerät 25 angeordnet, das durch eine Öffnung 26 in der Vorderwand 13 in den oberen Raumteil des Ofens 10 parallel zur Förderstrecke des Transportbandes 17 ausgerichtet ist. In "Blick"-Richtung des Wärmestrahlungsmeßgerätes 25 sind im oberen Raumteil des Ofens 10 oberhalb der Ebene der oberen IR-Strahler 21 mehrere flache, leistenförmige für IR-Strahlung geeignete Spiegel 30 angeordnet. Die Spiegelfläche der Planspiegel 30 weist gegen das Wärmestrahlungsmeßgerät 25 und ist zur Förderstrecke des Transportbandes 17 hin geneigt, so daß die von den auf dem Transportband 17 stehenden Behältern 1 nach oben emittierte Wärmestrahlung um etwa 90° zum Empfangsteil des Wärmestrahlungsmeßgeräts 25 umgelenkt wird. Um mehrere Felder im Ofen zu erfassen, sind die einzelnen Spiegel 30 in Förderrichtung des Transportbandes 17 und in der Höhe versetzt angeordnet, so daß sie in Deckung mit den Zwischenraumen zwischen den oberen IR-Strahlern 21 sind und sich in der Höhe zu einer geschlossenen Projektionsfläche ergänzen. Durch eine bestimmte Anordnung von mehreren Spiegeln im Ofen ist es möglich, mit einem einzigen Wärmestrahlungsmeßgerät die Temperaturverteilung der Behälter 1 im gesamten Ofen zu erfassen. Im Grunde genommen ist es aber schon ausreichend, dem Endbereich des Ofens, wo die Behälter 1 ihre höchste Temperatur erreicht haben, einen einzigen Spiegel zuzuordnen, mit dem ein sich über die gesamte Breite der Fördereinrichtung erstreckendes schmales Feld überwacht werden kann.To check whether the containers 1 conveyed by the furnace 10 are heated to the necessary sterilization temperature, a heat radiation measuring device 25 is arranged above the opening 18 in the front wall 13, which is parallel through an opening 26 in the front wall 13 in the upper part of the furnace 10 is aligned with the conveyor path of the conveyor belt 17. In the "gaze" direction of the heat radiation measuring device 25, a plurality of flat, strip-shaped mirrors 30 suitable for IR radiation are arranged in the upper part of the furnace 10 above the level of the upper IR radiators 21. The mirror surface of the plane mirror 30 faces the heat radiation measuring device 25 and is inclined towards the conveyor path of the conveyor belt 17, so that the heat radiation emitted upwards by the containers 1 standing on the transport belt 17 is deflected by approximately 90 ° to the receiving part of the heat radiation measuring device 25. In order to detect several fields in the furnace, the individual mirrors 30 are arranged offset in the conveying direction of the conveyor belt 17 and in height, so that they are in register with the interspaces between the upper IR radiators 21 and rise in height to form a closed projection surface complete. A certain arrangement of several mirrors in the furnace makes it possible to measure the temperature distribution of the containers 1 in the entire furnace with a single thermal radiation measuring device. Basically, however, it is sufficient to assign a single mirror to the end region of the furnace where the containers 1 have reached their highest temperature, with which a narrow field extending over the entire width of the conveyor device can be monitored.

Das Wärmestrahlungsmeßgerät 25 kann ein handelsübliches Pyrometer mit einem geeigneten Meßfeld sein und zusätzlich mit einer 1D- oder 2D-Ablenkeinheit ausgerüstet sein. Sehr gut eignet sich auch eine IR-Kamera, mit der aufgrund der bekannten Emissivität von Glas die Temperatur bestimmt werden kann. Eine IR-Kamera hat den Vorteil, daß die von den Spiegeln aus einer bestimmten Prüffläche reflektierte IR-Strahlung Zeile für Zeile und Punkt für Punkt abgetastet werden kann, so daß mit Hilfe eines geeigneten Rechen- oder Bildverarbeitungsprogrammes die empfangenen Temperatursignale aufbereitet und den einzelnen Meßpunkten, wie Öffnungsrand, Schulter oder Boden der Behälter 1, und auch die Oberfläche des Transportbandes 17 zwischen den Behältern 1 zugeordnet werden können.The heat radiation measuring device 25 can be a commercially available pyrometer with a suitable measuring field and can additionally be equipped with a 1D or 2D deflection unit. An IR camera with which the temperature can be determined due to the known emissivity of glass is also very suitable. An IR camera has the advantage that the IR radiation reflected from the mirrors from a specific test area can be scanned line by line and point by point, so that the temperature signals received and the individual measuring points can be processed with the aid of a suitable computing or image processing program , such as opening edge, shoulder or bottom of the container 1, and also the surface of the conveyor belt 17 between the containers 1 can be assigned.

Vorzugsweise werden die so ermittelten Temperaturprofile zur Leistungsregelung der Ofenheizung und/oder zur Geschwindigkeitsregelung des Transportbandes 17 herangezogen. Insbesondere die niedrigst gemessene Temperatur kann unabhängig davon, an welcher Stelle sie gemessen wurde, zur Leistungsregelung herangezogen werden. Hierdurch erübrigt sich die Suche nach einem geeigneten Referenzmeßpunkt, der sich bei unterschiedlichen Behältergrößen und damit unterschiedlichen Konvektionsbedingungen an verschiedenen Orten im Ofen einstellen kann. In Abänderung der fest eingestellten Spiegel im Ofen können solche auch um ihre Längsachse schwenkbar oder mit den Behältern 1 über eine bestimmte Strecke verfahrbar angeordnet sein, so daß durch synchrones Mitlaufen mit dem Behältern 1 eine Überwachung derselben Behälter über eine bestimmte Zeitdauer möglich ist.The temperature profiles determined in this way are preferably used to regulate the output of the furnace heating and / or to regulate the speed of the conveyor belt 17. In particular, the lowest measured temperature can be used for power control regardless of where it was measured. This eliminates the need to search for a suitable reference measuring point, which can be set at different locations in the furnace with different container sizes and thus different convection conditions. In a modification of the fixed mirrors in the oven, they can also be pivoted about their longitudinal axis or can be moved with the containers 1 over a certain distance, so that the same containers can be monitored over a certain period of time by synchronous running with the containers 1.

Ergänzend wird bewirkt, daß die Abkürzungen "IR" für Infrarot und "1D" sowie "2D" für Eindimension beziehungsweise Zweidimension stehen.In addition, the abbreviations "IR" stand for infrared and "1D" and "2D" for one-dimensional and two-dimensional.
