Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur stirnseitigen Inspektion eines queraxial geförderten stabförmigen Artikels in einer Maschine der Tabak verarbeitenden Industrie, umfassend mindestens eine rotierbar angetriebene Einstoßtrommel mit Umfangsmulden und eine Einführeinrichtung zum längsaxialen Einführen der stabförmigen Artikel in die Umfangsmulden, wobei an einer strangfernen Stirnseite der Einstoßtrommel ein Ausrichtelement vorgesehen ist, an dem die stabförmigen Artikel zur Anlage kommen, und eine optische Inspektionseinrichtung, die zur Inspektion einer Stirnfläche von in einem Erfassungsbereich der Inspektionseinrichtung angeordneten Filterstäben eingerichtet ist. Die Erfindung betrifft ebenfalls ein Verfahren zur stirnseitigen Inspektion eines queraxial geförderten stabförmigen Artikels in einer Maschine der Tabak verarbeitenden Industrie.The present invention relates to a device for inspecting the end face of a rod-shaped article conveyed transversely and axially in a machine in the tobacco processing industry, comprising at least one push-in drum driven in a rotatable manner with circumferential depressions and an insertion device for longitudinally axially introducing the rod-shaped article into the circumferential grooves, with the push-in drum being located on an end face remote from the strand an alignment element is provided, against which the rod-shaped articles come to rest, and an optical inspection device, which is set up for inspecting an end face of filter rods arranged in a detection area of the inspection device. The invention also relates to a method for inspecting the end face of a rod-shaped article conveyed transversely axially in a machine in the tobacco processing industry.

Vorrichtungen zur stirnseitigen Inspektion eines queraxial geförderten stabförmigen Artikels in einer Maschine der Tabak verarbeitenden Industrie sind beispielsweise aus der DE 10 2013 209 831 A1 und der EP 2 677 273 A1 bekannt.Devices for frontal inspection of a rod-shaped article conveyed transversely axially in a machine in the tobacco processing industry are, for example, from DE 10 2013 209 831 A1 and the EP 2 677 273 A1 known.

Bei gegenwärtigen Filterstabproduktionsmaschinen der Anmelderin wird Filtermaterial zu einem Filterstrang geformt. Der Filterstrang wird mittels einer Schneideinrichtung in Filterstäbe geschnitten, vereinzelt und längsaxial in die Umfangsmulden einer Einstoßtrommel eingeführt, mit der die Filterstäbe sodann queraxial gefördert und an eine nachgeordnete Abgabeeinrichtung abgegeben werden. An der von der Strangseite entfernten freien Stirnseite der Einstoßtrommel ist ein Anschlagring fest angebracht, an dem die längsaxial in die Umfangsmulden eingeführten Filterstäbe mit einer Stirnfläche zur Anlage gelangen, um diese auszurichten. Jedoch werden die Stirnflächen durch den Anschlagring verdeckt, so dass eine Inspektion der vorausseitigen Stirnflächen der Filterstäbe an der Einstoßtrommel nicht möglich ist. Eine Inspektion der vorausseitigen Stirnflächen der Filterstäbe wäre beispielsweise an einer nachgelagerten Abgabetrommel möglich, die keinen Anschlagring aufweist. Jedoch ist an der nachgelagerten Abgabeeinrichtung herkömmlicherweise keine Auswurfeinrichtung vorgesehen, mithilfe der als mangelhaft bewertete Artikel entfernt werden können. Eine zusätzliche Auswurfeinrichtung an einer nachgelagerten Abgabeeinrichtung erfordert jedoch zusätzlichen Bauraum und verursacht nicht unbeträchtliche zusätzliche Kosten.In the applicant's current filter rod production machines, filter material is formed into a filter rod. The filter strand is cut into filter rods by means of a cutting device, separated and inserted longitudinally axially into the peripheral depressions of a push-in drum with which the filter rods then be conveyed transversely axially and delivered to a downstream delivery device. A stop ring is fixedly attached to the free end face of the push-in drum remote from the strand side, on which the end face of the filter rods inserted longitudinally axially into the circumferential troughs come to rest in order to align them. However, the end faces are covered by the stop ring, so that it is not possible to inspect the front end faces of the filter rods on the push-in drum. An inspection of the front end faces of the filter rods would be possible, for example, on a downstream discharge drum that does not have a stop ring. However, conventionally, there is no ejector provided at the downstream dispenser for removing items judged defective. However, an additional ejection device on a downstream delivery device requires additional installation space and causes not inconsiderable additional costs.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung und ein Verfahren bereitzustellen, mit denen queraxial geförderte stabförmige Artikel in einer Maschine der Tabak verarbeitenden Industrie mit verringertem Gesamtaufwand stirnseitig inspiziert werden können.The object of the invention is to provide a device and a method with which rod-shaped articles conveyed transversely axially can be inspected from the front in a machine in the tobacco processing industry with a reduced overall effort.

Die Erfindung löst diese Aufgabe mit den Merkmalen der unabhängigen Ansprüche.The invention solves this problem with the features of the independent claims.

Aufgrund der erfindungsgemäß zwischen dem Ausrichtelement und der Einstoßtrommel vorgesehenen Relativbewegung wird am Umfang der Einstoßtrommel ein Inspektionsbereich geschaffen, der von dem Ausrichtelement frei ist und in dem daher vorteilhaft eine Inspektionseinrichtung angeordnet werden kann. Die stabförmigen Artikel können somit erfindungsgemäß an der Einstoßtrommel inspiziert und ggf. bei Ermittlung einer nicht einwandfreien Stirnfläche mit einer an der Einstoßtrommel vorgesehenen Auswurfeinrichtung aus dem Produktstrom ausgeschleust werden.Due to the relative movement provided according to the invention between the aligning element and the push-in drum, an inspection area is created on the circumference of the push-in drum which is free of the aligning element and in which an inspection device can therefore advantageously be arranged. the According to the invention, rod-shaped articles can thus be inspected on the push-in drum and, if necessary, ejected from the product flow with an ejection device provided on the push-in drum if an end face is found to be imperfect.

Der von dem Ausrichtelement freie Inspektionsbereich kann in einer vorteilhaften Ausführungsform durch partielle Entfernung des Ausrichtelements von der Einstoßtrommel in einem Umfangsbereich infolge der erfindungsgemäßen Relativbewegung geschaffen werden. Dies kann in der Praxis vorteilhaft durch Verwendung eines endlos umlaufenden Zugmittels, insbesondere eines Bandes, Riemens oder einer Kette als Ausrichtelement erreicht werden.In an advantageous embodiment, the inspection area free of the alignment element can be created by partial removal of the alignment element from the push-in drum in a circumferential area as a result of the relative movement according to the invention. In practice, this can advantageously be achieved by using an endlessly circulating traction means, in particular a band, belt or chain, as the alignment element.

In einer alternativen vorteilhaften Ausführungsform ist das Ausrichtelement stationär bzw. maschinen- oder ortsfest angeordnet, so dass sich das Ausrichtelement nicht mit der Einstoßtrommel dreht. Der von dem Ausrichtelement freie Inspektionsbereich wird dann vorteilhaft von einer mindestens einem stabförmigen Artikel entsprechenden Inspektionsaussparung oder Bohrung in dem Ausrichtelement gebildet. In dieser Ausführungsform weist das Ausrichtelement vorzugsweise die Form eines Kreisbogens auf. Die Inspektionsaussparung kann vorteilhaft als optische Sammellinse oder Zylinderlinse ausgebildet sein.In an alternative advantageous embodiment, the aligning element is arranged in a stationary manner or fixed to the machine or location, so that the aligning element does not rotate with the push-in drum. The inspection area free of the alignment element is then advantageously formed by an inspection recess or bore in the alignment element corresponding to at least one rod-shaped article. In this embodiment, the alignment element preferably has the shape of an arc of a circle. The inspection recess can advantageously be designed as an optical converging lens or cylindrical lens.

Die Erfindung ist grundsätzlich auf sämtliche Maschinen zur Herstellung stabförmiger Artikel, insbesondere von Filterstäben oder Tabakstöcken, der Tabak verarbeitenden Industrie vorteilhaft anwendbar.

Vorteilhaft ist die Anwendung der Erfindung für solche Maschinen, bei denen die Einstoßtrommel fliegend gelagert und das Ausrichtelement am freien Ende der Einstoßtrommel angeordnet ist, weil hier kein Lager an dem strangfernen Ende der Einstoßtrommel zum Befestigen des Ausrichtelements vorhanden ist. Eine bevorzugte Anwendung betrifft des Weiteren eine Zweistrangmaschine mit einer oder mit zwei Einstoßtrommeln, zugeordneten Abgabeförderern (Muldenbänder oder Muldentrommeln) und zugeordneten Entnahmeförderern (Muldenbänder oder Muldentrommeln), wobei zwei parallel angeordnete Einführeinrichtungen vorgesehen sind.In principle, the invention can advantageously be applied to all machines for the production of rod-shaped articles, in particular filter rods or tobacco rods, in the tobacco processing industry.

Dies kann beispielsweise mittels einer in Bewegungsrichtung der Filterstäbe 16 wirkenden Luftdüse 20 geschehen. Damit die Filterstäbe 16 zueinander ausgerichtet sind, ist am strangfernen Ende 19 der Einstoßtrommel ein vorzugsweise bogenförmiges Ausricht- oder Anschlagelement 21 angeordnet, das in der Fig. 1 nur schematisch dargestellt ist und anhand der Fig. 2 bis Fig. 6 genauer erläutert werden wird.For transfer from the strand area 12 to the drum area 14, the filter rods 6 are introduced into circumferential grooves 10 of a push-in drum 13 by means of the transfer device 8, here a guide wheel having a helical groove. The transfer point 17 from the line is at twelve o'clock, for example, as in 2 shown. In the circumferential grooves 10, the filter rods 6 are displaced from the end 18 on the strand side to the end 19 of the push-in drum 13 which is remote from the strand. This can be done, for example, by means of an air nozzle 20 acting in the direction of movement of the filter rods 16 . In order for the filter rods 16 to be aligned with one another, a preferably arcuate alignment or stop element 21 is arranged at the end 19 of the push-in drum which is remote from the strand 1 is shown only schematically and based on the Figures 2 to 6 will be explained in more detail.

Die Einstoßtrommel 13 ist um ihre Längsachse drehbar gelagert, und zwar insbesondere einseitig bzw. fliegend an dem strangseitigen Ende der Einstoßtrommel 13. Durch Rotation der Einstoßtrommel 13 mittels eines nicht gezeigten Drehantriebs werden die an dem Ausrichtelement 21 ausgerichteten Filterstäbe 6 in der Drehrichtung der Einstoßtrommel 13, hier im Gegenuhrzeigersinn, von der Übergabeposition 17 bis zu einer Abgabeposition 22 an eine nachgeordnete Abgabeeinrichtung, hier die Abgabetrommel 16, gefördert. An dem Abgabepunkt 22 werden die Filterstäbe 6 an die Abgabetrommel 16 abgegeben und mit dieser abgefördert, um beispielsweise einen Filterstab-Massenstrom 23 zu bilden.The push-in drum 13 is rotatably mounted about its longitudinal axis, in particular on one side or overhung on the strand-side end of the push-in drum 13. By rotating the push-in drum 13 by means of a rotary drive (not shown), the filter rods 6 aligned on the alignment element 21 are rotated in the direction of rotation of the push-in drum 13 , here counterclockwise, from the transfer position 17 to a delivery position 22 to a downstream delivery device, here the delivery drum 16, promoted. At the delivery point 22, the filter rods 6 are delivered to the delivery drum 16 and conveyed away with it in order to form a filter rod mass flow 23, for example.

Zwischen der Übergabeposition 17 und der Abgabeposition 22 ist eine beispielsweise optische Inspektionseinrichtung 24, insbesondere eine Kamera, am Umfang der Einstoßtrommel 13 angeordnet, die zur Inspektion der strangfernen Stirnfläche eines oder mehrerer in einem Erfassungsbereich 25 der Inspektionseinrichtung 24 angeordneter Filterstäbe 6a eingerichtet und angeordnet ist. Die Inspektion erfolgt von der strangfernen Seite 19 der Einstoßtrommel 13. Die von der Inspektionseinrichtung 24 aufgenommenen Daten werden von einer elektronischen Datenverarbeitungseinrichtung 26, die beispielsweise auch in der Inspektionseinrichtung 24 angeordnet sein kann, dahingehend ausgewertet, ob die inspizierte Stirnfläche einwandfrei oder mangelhaft ist. Zwischen der Inspektionseinrichtung 24 und der Abgabeposition 22 ist ein Ausstoßer 27 angeordnet, der mittels einer elektronischen Steuereinrichtung 28, die von der Datenverarbeitungseinrichtung 26 oder separat ausgebildet sein kann, ansteuerbar ist, um als mangelhaft erkannte Filterstäbe 6a auszustoßen. Der Ausstoßer 27 kann beispielsweise eine Luftdüse sein, die zur Erzeugung eines entgegen der Strangförderrichtung gerichteten Luftstoßes eingerichtet ist.An optical inspection device 24, for example, in particular a camera, is arranged on the circumference of push-in drum 13 between transfer position 17 and delivery position 22. The inspection is carried out from the side 19 of the insertion drum 13 remote from the strand Inspection device 24 recorded data are evaluated by an electronic data processing device 26, which can also be arranged in the inspection device 24, for example, to determine whether the inspected end face is flawless or defective. An ejector 27 is arranged between the inspection device 24 and the delivery position 22, which can be controlled by an electronic control device 28, which can be embodied by the data processing device 26 or separately, in order to eject filter rods 6a identified as defective. The ejector 27 can be an air nozzle, for example, which is set up to generate an air blast directed counter to the strand conveying direction.

Die Inspektionseinrichtung 24 ist vorzugsweise so angeordnet, dass der Erfassungsbereich 25 in einem Winkelbereich zwischen 45° und 180°, beispielsweise etwa 90°, hinter der Übergabeposition 17 liegt. Der Ausstoßer 27 ist beispielsweise in einem Winkelbereich zwischen 180° und 315°, beispielsweise etwa 225° hinter der Übergabeposition 17 angeordnet. Der Winkel zwischen dem Erfassungsbereich 25 und dem Ausstoßer 27 beträgt vorzugsweise mindestens 45°, weiter vorzugsweise mindestens 90°, beispielsweise etwa 135°, damit ausreichend Zeit für die Datenverarbeitung bleibt.The inspection device 24 is preferably arranged in such a way that the detection area 25 lies behind the transfer position 17 in an angular range between 45° and 180°, for example approximately 90°. The ejector 27 is arranged, for example, in an angular range between 180° and 315°, for example approximately 225° behind the transfer position 17 . The angle between the detection area 25 and the ejector 27 is preferably at least 45°, more preferably at least 90°, for example approximately 135°, so that there is sufficient time for data processing.

Damit die Stirnflächen der zu untersuchenden Filterstäbe 6a im Erfassungsbereich 25 der Inspektionseinrichtung 24 nicht von dem Ausrichtelement 21 verdeckt wird, wird erfindungsgemäß eine Relativbewegung zwischen dem Ausrichtelement 21 und der Einstoßtrommel 13 erzeugt. In der Ausführungsform gemäß den Fig. 2 bis Fig. 4 wird die erfindungsgemäße Relativbewegung dadurch realisiert, dass das Ausrichtelement 21 ortsfest bzw. stationär oder maschinenfest montiert ist und eine Aussparung 29 aufweist, durch die hindurch die Stirnflächeninspektion mittels der Inspektionseinrichtung 24 stattfinden kann. Genauer ist die Inspektionseinrichtung 24 so angeordnet, dass ihr Blickfeld und der Erfassungsbereich 25 in der Aussparung 29 liegen, so dass eine ungestörte Inspektion der Stirnfläche eines in dem Erfassungsbereich befindlichen Filterstabs 6a möglich ist.So that the end faces of the filter rods 6a to be examined are not covered by the alignment element 21 in the detection area 25 of the inspection device 24, a relative movement is generated between the alignment element 21 and the push-in drum 13 according to the invention. In the embodiment according to FIG Figures 2 to 4 the relative movement according to the invention is realized in that the alignment element 21 is mounted stationary or fixed to the machine and a recess 29, through which the end face inspection can take place by means of the inspection device 24. More precisely, the inspection device 24 is arranged in such a way that its field of view and the detection area 25 lie in the recess 29, so that an undisturbed inspection of the end face of a filter rod 6a located in the detection area is possible.

In der Ausführungsform gemäß den Fig. 2 bis Fig. 4 ist das Ausrichtelement 21 vorteilhaft bogenförmig und bildet mit der Aussparung 29 einen vollen Kreis (360°). Die Winkelerstreckung des Ausrichtelements 21 ist in weiten Bereichen variierbar. Beispielsweise in der Ausführungsform gemäß Fig. 2 beträgt die Winkelerstreckung des Ausrichtelements 21 mehr als 270°, beispielsweise 330°, und demnach die Winkelerstreckung der Aussparung 29 weniger als 90°, beispielsweise 30°. In der Ausführungsform gemäß Fig. 3 beträgt die Winkelerstreckung des Ausrichtelements 21 vorzugsweise mehr als 30°, weiter vorzugsweise mehr als 60°, beispielsweise knapp 90°, und demnach die Winkelerstreckung der Aussparung 29 weniger als 330°, vorzugsweise weniger als 300°, beispielsweise etwas mehr als 270°. In der Ausführungsform gemäß Fig. 4 ist die minimale, d.h. mindestens erforderliche Erstreckung der Aussparung 29 von weniger als 10° gezeigt, die an den Durchmesser einer zu inspizierenden Stirnfläche angepasst ist. Die Winkelerstreckung des Ausrichtelements 21 beträgt hier beispielsweise mehr als 350°.In the embodiment according to FIG Figures 2 to 4 the alignment element 21 is advantageously arcuate and forms a full circle (360°) with the recess 29 . The angular extent of the alignment element 21 can be varied within wide ranges. For example, in the embodiment according to FIG 2 the angular extent of the alignment element 21 is more than 270°, for example 330°, and accordingly the angular extent of the recess 29 is less than 90°, for example 30°. In the embodiment according to 3 the angular extent of the alignment element 21 is preferably more than 30°, more preferably more than 60°, for example almost 90°, and accordingly the angular extent of the recess 29 is less than 330°, preferably less than 300°, for example slightly more than 270°. In the embodiment according to 4 shows the minimum, ie at least required, extension of the recess 29 of less than 10°, which is adapted to the diameter of an end face to be inspected. The angular extension of the alignment element 21 is more than 350° here, for example.

Anstelle der Aussparung 29 kann auch eine Bohrung in einem beispielsweise ring- oder bogenförmigen Ausrichtelement 21 vorgesehen sein.Instead of the recess 29, a bore can also be provided in an alignment element 21, for example in the form of a ring or arc.

In den Ausführungsformen gemäß Fig. 5 und Fig. 6 ist das Ausrichtelement 21 ein endlos umlaufendes Zugmittel 38, hier in Form eines Endlos-Bandes, das am strangfernen Ende 19 der Einstoßtrommel 13 über einen bogenförmigen Teilbereich 30 am Umfang der Einstoßtrommel 13 anliegend geführt ist. Das Zugmittel 38 ist dabei mittels mindestens eines in Fig. 5 nur schematisch dargestellten Umlenkmittels 31, beispielsweise einer oder mehrerer Umlenkrollen 31 so geführt, dass das Zugmittel 38 an einer Umfangsposition 32 zwischen dem Übergabepunkt 17 und dem Erfassungsbereich 25 von der Einstoßtrommel 13 abgehoben und an einer Umfangsposition 33 hinter dem Erfassungsbereich 25 wieder an die Einstoßtrommel 13 herangeführt. Auf diese Weise wird zwischen den beiden beschriebenen Umfangspositionen 32, 33 ein bogenförmiger Teilbereich 34 am Umfang der Einstoßtrommel 13 erzeugt, an dem das Zugmittel 38 von der Einstoßtrommel 13 entfernt ist. Die Inspektionseinrichtung 24 ist so angeordnet, dass ihr Blickfeld und der Erfassungsbereich 25 in dem von dem Zugmittel 38 freien Umfangsbereich 34 liegen, so dass eine ungestörte Inspektion der Stirnfläche eines in dem Erfassungsbereich 25 befindlichen Filterstabs 6a möglich ist. Die Relativbewegung zwischen dem Ausrichtelement 21 und der Einstoßtrommel 13 wird hier durch Abheben des Ausrichtelements 21 von der Einstoßtrommel 13 realisiert.In the embodiments according to figure 5 and 6 the alignment element 21 is an endlessly revolving traction mechanism 38, here in Form of an endless belt, which is guided at the end 19 of the push-in drum 13 that is remote from the strand over an arcuate portion 30 on the circumference of the push-in drum 13. The traction mechanism 38 is connected by means of at least one in figure 5 deflection means 31, shown only schematically, for example one or more deflection rollers 31, so that the traction means 38 is lifted off the push-in drum 13 at a circumferential position 32 between the transfer point 17 and the detection area 25 and back to the push-in drum 13 at a circumferential position 33 behind the detection area 25 introduced. In this way, between the two circumferential positions 32, 33 described, an arcuate partial area 34 is produced on the circumference of the push-in drum 13, at which the traction means 38 is removed from the push-in drum 13. The inspection device 24 is arranged in such a way that its field of view and the detection area 25 lie in the peripheral area 34 free of the traction means 38, so that an undisturbed inspection of the end face of a filter rod 6a located in the detection area 25 is possible. The relative movement between the alignment element 21 and the insertion drum 13 is realized here by lifting the alignment element 21 off the insertion drum 13 .

In der Ausführungsform gemäß Fig. 5 wird das beispielsweise als Zahnriemen ausgeführte Endloszugmittel 38 durch die Einstoßtrommel 13 angetrieben, die zu diesem Zweck eine Verzahnung aufweisen kann. In einer alternativen Ausführungsform kann das Endloszugmittel 38 durch einen separaten Antrieb angetrieben sein, der beispielsweise durch eine angetriebene Umlenkrolle 31 realisiert sein kann. In diesem Fall ist der separate Antrieb des Endloszugmittels 21 zweckmäßigerweise mit dem Antrieb der Einstoßtrommel 13 synchronisiert.In the embodiment according to figure 5 For example, the endless traction means 38, designed as a toothed belt, is driven by the push-in drum 13, which can have teeth for this purpose. In an alternative embodiment, the endless traction means 38 can be driven by a separate drive, which can be realized, for example, by a driven deflection roller 31 . In this case, the separate drive of the endless traction means 21 is expediently synchronized with the drive of the push-in drum 13 .

Bei der Ausführungsform gemäß Fig. 5 ist das Zugmittel 38 so geführt, dass die Einstoßtrommel 13 im Inneren der von dem Zugmittel 38 gebildeten Schleife angeordnet ist. Bei der Ausführungsform gemäß Fig. 6 ist das Zugmittel 38 vollständig radial außerhalb der Einstoßtrommel 13 angeordnet. In diesem Ausführungsbeispiel weist das Zugmittel 38 ein sich gegenläufig zu der Einstoßtrommel 13 bewegendes Rücktrum 40 auf. Die Ausführungsform gemäß Fig. 6 kann gegenüber der Ausführungsform gemäß Fig. 5 bevorzugt sein, da das Zugmittel 38 hier kürzer sein kann und insgesamt weniger Bauraum einnimmt.In the embodiment according to figure 5 the traction means 38 is guided in such a way that the push-in drum 13 is arranged inside the loop formed by the traction means 38 . In the embodiment according to 6 the traction means 38 is arranged completely radially outside of the push-in drum 13 . In this exemplary embodiment, the traction mechanism 38 has a return strand 40 that moves in the opposite direction to the push-in drum 13 . The embodiment according to 6 can according to the embodiment figure 5 be preferred since the traction mechanism 38 can be shorter here and takes up less overall space.

Die Ausführungsformen gemäß Fig. 5 und Fig. 6 sind besonders vorteilhaft, falls in Transportrichtung hinter der Übergabeposition 17 eine Saugeinrichtung 35 vorgesehen ist, die eine sich über einen Umfangsabschnitt erstreckende, dem Ausrichtelement 21 zugewandte Saugöffnung 36 aufweist. In dem Ausrichtelement 21 sind Öffnungen 37 vorgesehen, wobei jeweils einer Umfangsmulde 10 der Einstoßtrommel 13 eine Öffnung 37 zugeordnet ist. Bei der Verschiebung der Filterstäbe 6 in den Umfangsnuten 10 von dem strangseitigen Ende 18 zu dem strangfernen Ende 19 der Einstoßtrommel 13 werden die Filterstäbe 6 beispielsweise mittels nicht gezeigten Saugöffnungen in den Umfangsnuten abgebremst und schließlich an dem strangfernen Ende 19 der Einstoßtrommel 13 durch Anlegen eines Unterdrucks an die Saugöffnung 36 und somit auch an die im Bereich der Saugöffnung 36 befindlichen Öffnungen 37 in dem Ausrichtelement 21 kontrolliert an das Ausrichtelement 21 herangezogen. In dieser Ausführungsform verhindert das an der Einstoßtrommel 13 eng oder dichtend anliegende Ausrichtelement 21 eine Reduzierung der von der Saugeinrichtung 35 bereitgestellten Saugleistung. The embodiments according to figure 5 and 6 are particularly advantageous if a suction device 35 is provided behind the transfer position 17 in the transport direction, which suction device has a suction opening 36 that extends over a circumferential section and faces the alignment element 21 . Openings 37 are provided in the aligning element 21 , one opening 37 being assigned to each circumferential depression 10 of the push-in drum 13 . When the filter rods 6 are displaced in the circumferential grooves 10 from the end 18 on the strand side to the end 19 of the push-in drum 13 remote from the strand, the filter rods 6 are decelerated, for example by means of suction openings (not shown) in the circumferential grooves, and finally at the end 19 of the push-in drum 13 remote from the strand by applying a vacuum to the suction opening 36 and thus also to the openings 37 located in the area of the suction opening 36 in the aligning element 21 in a controlled manner. In this embodiment, the alignment element 21 lying tightly or sealingly against the push-in drum 13 prevents a reduction in the suction power provided by the suction device 35 .
