- the filter plug 52 is in the closest approach to the helical microwave resonator 250.
- the illustrated configuration may be operated at a microwave frequency of 5.58 GHz.
- the microwave measuring device 60 comprises a resonator housing 432, which encloses a microwave resonator 434.
- the microwave resonator 434 is a cavity which is enclosed by electrically conductive walls of the resonator housing 432 and in which a microwave measuring field can form.
- Fig. 7a) and 7c also show parts of a coordinate system with an x-axis, a y-axis and a z-axis.

- this position of the capsule 55 could also be set to a position at which the microwave measuring field has a wave node. In this case, there is a change in the microwave measuring field only if the capsule 55 does not occupy this desired position and thus feels an electric field which is not equal to zero, that is does not have the vanishing field strength of the wave node. In this case, a difference to a signal change is considered, which is caused by filter material anyway.

Dadurch, dass die Fördertrommel einen äußeren Trommelkörper aufweist, wobei die Aufnahmemulden der beiden Reihen gegenüber der Umfangsfläche des Trommelkörpers der Fördertrommel in radialer Richtung nach außen versetzt ausgebildet sind, sind die Aufnahmemulden für die stabförmigen Artikel gegenüber dem Trommelkörper der Fördertrommel mit einer Erhöhung in radialer Richtung angeordnet, wodurch es ermöglicht ist, dass die freien Enden der zu prüfenden Abschnitte der stabförmigen Artikel bei Rotation der Fördertrommel in den Durchtrittskanal eingebracht werden.Characterized in that the conveyor drum has an outer drum body, wherein the receiving troughs of the two rows are offset from the peripheral surface of the drum body of the conveyor drum outwardly in the radial direction, the receiving troughs for the rod-shaped article relative to the drum body of the conveyor drum with an increase in the radial direction arranged, whereby it is possible that the free ends of the portions to be tested of the rod-shaped articles are introduced during rotation of the conveyor drum in the passageway.
Hierbei sind insbesondere die geförderten stabförmigen Artikel einseitig in einem vorbestimmten Abschnitt der stabförmigen Artikel in den verkürzten Aufnahmemulden angeordnet, wobei der Abschnitt der stabförmigen Artikel, die in den dafür vorgesehenen Aufnahmemulden mit Unterdruck beaufschlagt werden, um die stabförmigen Artikel während der Förderung auf der Fördertrommel mittels Unterdruck zu halten.In this case, in particular, the conveyed rod-shaped articles are arranged on one side in a predetermined section of the rod-shaped articles in the shortened receiving troughs, wherein the portion of the rod-shaped articles, which are subjected to negative pressure in the receptacles provided therefor, by the rod-shaped articles during the promotion on the conveyor drum To keep negative pressure.
Hierzu ist in einer Weiterbildung der Trommelanordnung weiterhin vorgesehen, das die Aufnahmemulden der beiden Reihen in oder auf radial nach außen sich erstreckenden, insbesondere scheibenförmigen, Ringkörpern oder in oder auf radial nach außen sich erstreckenden Ärmchen ausgebildet sind.

Die Anordnung umfasst eine Mikrowellenmessvorrichtung 60 mit einem Gehäuse 72, das einen Reflexionsresonator 74 mit einer Mikrowelleneinkopplung 80 umfasst. Eine Blende 84 ist gestrichelt angedeutet und trennt den Mikrowelleneinkopplungshohlraum 80 vom Reflexionsresonator 74 ab. Im oberen Bereich ist der Reflexionsresonator 74 durchbrochen von einem Durchtrittskanal 62, der gabelförmig ausgebildet ist. Dieser umfasst eine erste Wandung 64 und eine zweite Wandung 66 und ist mittels einer Abschlusswand 68 seitlich abgeschlossen. Damit ist der Durchtrittskanal 62 im Querschnitt "U"-förmig. Dadurch wird verhindert, dass das Mikrowellenfeld im Inneren des Resonators in größerem Maße austritt. Dazu trägt bei, dass die erste Wandung 64 und die zweite Wandung 66 deutlich über den Resonatorhohlraum hinausragen.The arrangement comprises a
Durch den Durchtrittskanal 62 verläuft ein Förderweg 100 von stabförmigen Artikeln, in diesem Fall Filterzigaretten 50, die einen Tabakstock 51, der nur teilweise dargestellt ist, sowie Filterstopfen 52 mit Kapseln 55 umfassen.Through the
Der Resonatorhohlraum selbst ist mittels Schutzblenden 326, 327, die aus einem für Mikrowellen durchlässigen Material bestehen, beispielsweise PEEK (Polyetheretherketon), abgedeckt. Dies verhindert, dass Schmutz in den Mikrowellenresonator eindringt. Durch die Schutzblenden 326, 327 ist der Reflexionsresonator 74 in drei Resonatorhohlraumabschnitte 325, 325', 325" aufgeteilt.The resonator cavity itself is covered by means of
Die Mikrowellenmessvorrichtung 60 umfasst mehrere Teile. Die Mikrowellen werden in einer Mikrowelleneinkopplung eingekoppelt, die einen Mikrowelleneinkopplungshohlraum 330 und eine Antenne 336 umfasst, die sowohl als Einkopplungsantenne als auch als Auskopplungsantenne betrieben wird. Hierdurch wird auch Bauraum eingespart. Der Mikrowelleneinkopplungshohlraum 330 wird begrenzt durch eine Wand mit einer kreisförmigen oder ovalen Blende 84, durch die Mikrowellen in den Resonatorhohlraum 124 eindringen. Die Blendenöffnung kann auch andere Formen haben, oder es sind mehrere Blendenöffnungen möglich, wobei diese beispielsweise entsprechend der einzuspeisenden Mode des Mikrowellenfeldes wählbar sein kann.The
Der Resonatorhohlraum 124 ist durch den Durchtrittskanal 62 in zwei separate Teile bzw. Resonatorhohlraumabschnitte 325, 325' geteilt. Die Fortsetzung des Resonatorhohlraums 124 im Durchtrittskanal 62 selbst kann als weiterer Resonatorhohlraumabschnitt 325" angesehen werden. Die Schutzblenden 326, 327, die diese Resonatorhohlraumabschnitte 325, 325' des Resonatorhohlraums 124 vom Durchtrittskanal 62 trennen, sind für Mikrowellen durchlässig, so dass sich ein gemeinsamer Resonatorhohlraum 124 mit zwei bzw. drei Teilen bzw. Teilräumen, den Resonatorhohlraumabschnitten 325, 325', 325" ergibt. Der mittlere Resonatorhohlraumabschnitt 325" ist dabei derjenige, der im Durchtrittskanal 62 liegt, während die beiden anderen durch mikrowellendurchlässige Schutzblenden 326, 327 vor Verschmutzung geschützt sind, so dass eine gleichbleibend hohe Güte des Reflexionsresonators 121 gewährleistet ist.The
Der Resonatorhohlraum 124 ist durch eine Reflexionsfläche 332, die der Blende 84 gegenüberliegt, abgeschlossen. Mikrowellen, die durch die Blende 84 in den Resonatorhohlraum 124 gelangen, werden an der Reflexionsfläche 332 reflektiert und gelangen zurück durch die Blende 84 zur Antenne 336. Dabei durchlaufen sie zweifach den Durchtrittskanal 62 mit gegebenenfalls darin positionierten Filterstopfen 52 und Kapseln 55.The

In einer alternativen Ausbildung könnte auch diese Position der Kapsel 55 an eine Stelle gesetzt sein, an der das Mikrowellenmessfeld einen Wellenknoten aufweist. In diesem Fall ergibt sich eine Änderung des Mikrowellenmessfeldes nur, falls die Kapsel 55 diese Sollposition nicht einnimmt und somit ein elektrisches Feld verspürt, das nicht gleich Null ist, also nicht die verschwindende Feldstärke des Wellenknotens aufweist. Dabei wird eine Differenz zu einer Signaländerung betrachtet, die von Filtermaterial ohnehin verursacht wird.In an alternative embodiment, this position of the
Im oberen Bereich ist zu erkennen, dass eine Antenne 436 durch einen nicht leitenden Abschnitt der Resonatorwand 440 hindurchgeführt ist und mit einer Elektronik 438 in Kontakt steht, die dafür in das Resonatorgehäuse eingelassen ist. Diese Elektronik 438 kann beispielsweise eine Sendeelektronik sein, die das Mikrowellenmessfeld erzeugt und durch die Antenne 436 in den Mikrowellenresonator 434 einkoppelt. Im unteren Bildbereich ist zu erkennen, dass in einer gleichartigen Konfiguration die Antenne 436' ebenfalls mit einer Elektronik 438' außerhalb des Mikrowellenresonators 434 verbunden ist. Hierbei kann es sich um eine Mess- und Auswerteelektronik 438' handeln, die Änderungen des Messfelds registriert und auswertet. Bei der Antenne 436' handelt es sich somit um eine Auskoppelantenne.In the upper area it can be seen that an
