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.
Vorrichtungen zur stirnseitigen Inspektion eines queraxial geförderten stabförmigen Artikels in einer Maschine der Tabak verarbeitenden Industrie sind beispielsweise aus der WO 2010/028354 A1 , der DE 10 2013 209 831 A1 und der EP 2 677 273 A1 bekannt.
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.The present invention relates to a device for the end-face inspection of a cross-axially conveyed rod-shaped article in a machine of the tobacco processing industry, comprising at least one rotatably driven insertion drum with peripheral troughs and an insertion device for longitudinal axial insertion of the rod-shaped articles in the circumferential wells, wherein at a distal end face of the insertion drum an alignment element is provided, on which the rod-shaped articles come to rest, and an optical inspection device, which is set up to inspect an end face of filter rods arranged in a detection region of the inspection device. The invention also relates to a method for the frontal inspection of a cross-axially promoted rod-shaped article in a machine of the tobacco-processing industry.
Devices for the frontal inspection of a cross-axially promoted rod-shaped article in a machine of the tobacco processing industry are, for example, from WO 2010/028354 A1 , of the DE 10 2013 209 831 A1 and the EP 2 677 273 A1 known.
Applicant's current filter rod production machines form filter material into a filter strand. The filter strand is cut by means of a cutting device into filter rods, isolated and longitudinally inserted into the circumferential wells of a push-in drum, with which the filter rods then conveyed transaxially and delivered to a downstream dispenser. At the remote from the strand side free end face of the injection drum, a stop ring is fixedly mounted on which the längsaxially introduced into the circumferential wells filter rods come to rest with an end face to align them. However, the end faces are covered by the stop ring, so that an inspection of the front-side end faces of the filter rods on the insertion drum is not possible. An inspection of the front-side end faces of the filter rods would be possible, for example, on a downstream dispensing drum, which has no stop ring. However, conventionally, no ejector is provided on the downstream dispenser that can be used to remove articles that are deemed defective. However, an additional ejector on a downstream dispenser requires additional 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 cross-axially promoted rod-shaped articles in a machine of the tobacco-processing industry can be inspected frontally with reduced total 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 kann am Umfang der Einstoßtrommel ein Inspektionsbereich geschaffen werden, 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.Because of the relative movement provided according to the invention between the alignment element and the insertion drum, an inspection area can be created on the circumference of the insertion drum, which area is free of the alignment 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 insertion drum and, if necessary, be ejected from the product flow upon detection of an imperfect end face with an ejection device provided on the insertion drum.

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 which is free of the alignment element can be created by partial removal of the alignment element from the insertion drum in a peripheral area as a result of the relative movement according to the invention. This can be advantageously achieved in practice by using an endlessly circulating traction means, in particular a belt, belt or chain as an 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 alignment element is arranged stationary or machine or stationary, so that the alignment element does not rotate with the insertion drum. The inspection area which is 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 a circular arc. The inspection recess can advantageously be designed as an optical converging lens or cylindrical lens.

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.The invention is fundamentally advantageously applicable to all machines for producing rod-shaped articles, in particular filter rods or tobacco sticks, of the tobacco-processing industry.

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 the transfer of the strand area 12 to the drum area 14, the filter rods 6 are introduced by means of the transfer device 8, here a guide wheel having a helical groove, in circumferential grooves 10 of a push-in drum 13. The transfer point 17 from the line is for example at twelve o'clock, as in Fig. 2 shown. In the circumferential grooves 10, the filter rods 6 are displaced from the strand-side end 18 to the distal end 19 of the insertion drum 13. This can be done, for example, by means of an air nozzle 20 acting in the direction of movement of the filter rods 16. Thus, the filter rods 16 are aligned with each other, a preferably arcuate alignment or stop element 21 is arranged at the distal end 19 of the insertion drum, which in the Fig. 1 is shown only schematically and based on the Fig. 2 to Fig. 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 insertion drum 13 is rotatably supported about its longitudinal axis, and in particular one-way or flying on the strand-side end of the insertion drum 13. By rotation of the insertion drum 13 by means of a rotary drive, not shown, the aligned on the alignment element 21 filter rods 6 in the direction of rotation of the insertion drum 13th , here counterclockwise, from the transfer position 17 to a discharge position 22 to a downstream dispenser, here the dispensing drum 16, promoted. At the discharge point 22, the filter rods 6 are delivered to the discharge drum 16 and conveyed away with this, for example, to form a filter rod mass flow 23.

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 zweckmäßigerweise 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.Between the transfer position 17 and the discharge position 22, an optical inspection device 24, in particular a camera, is arranged on the circumference of the insertion drum 13, which is set up and arranged for inspection of the strand-remote end face of one or more filter rods 6a arranged in a detection region 25 of the inspection device 24. The inspection is expediently carried out from the strand-side 19 of the insertion drum 13. The inspection of the device 24 recorded data are evaluated by an electronic data processing device 26, which may for example also be arranged in the inspection device 24, to the effect whether the inspected face is perfect or poor. Between the inspection device 24 and the discharge position 22, an ejector 27 is arranged, which can be controlled by means of an electronic control device 28, which may be formed by the data processing device 26 or separately, to eject as poorly recognized filter rods 6a. The ejector 27 may be, for example, an air nozzle, which is set up to produce a directed against the strand conveying direction air blast.

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 such that the detection region 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 about 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 about 135 °, so that sufficient time remains for the 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 region 25 of the inspection device 24, a relative movement between the alignment element 21 and the insertion drum 13 is generated according to the invention. In the embodiment according to the Fig. 2 to Fig. 4 the relative movement according to the invention is realized in that the alignment element 21 is stationary or stationary or fixed to the machine mounted and a recess 29, through which the end face inspection can take place by means of the inspection device 24. More specifically, the inspection device 24 is arranged so 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 the Fig. 2 to Fig. 4 is the alignment member 21 advantageously arcuate and forms with the recess 29 a full circle (360 °). 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 therefore the angular extent of the recess 29 is less than 90 °, for example 30 °. In the embodiment according to Fig. 3 the angular extent of the alignment element 21 is preferably more than 30 °, more preferably more than 60 °, for example just under 90 °, and thus 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 Fig. 4 is the minimum, ie at least required extent of the recess 29 of less than 10 ° shown, which is adapted to the diameter of a face to be inspected. The angular extent of the alignment element 21 is here, for example, more than 350 °.

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

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 Fig. 5 and Fig. 6 the alignment element 21 is an endlessly circulating traction mechanism 38, here in FIG Shape of an endless belt, which is guided at the distal end 19 of the insertion drum 13 via an arcuate portion 30 adjacent to the circumference of the insertion drum 13. The traction means 38 is by means of at least one in Fig. 5 only schematically illustrated deflection 31, for example, one or more guide rollers 31 guided so that the traction means 38 lifted at a circumferential position 32 between the transfer point 17 and the detection area 25 of the insertion drum 13 and at a peripheral position 33 behind the detection area 25 back to the insertion drum 13th introduced. In this way, between the two described circumferential positions 32, 33, a curved portion 34 is produced on the circumference of the insertion drum 13, on which the traction means 38 is removed from the insertion drum 13. The inspection device 24 is arranged so that its field of view and the detection area 25 lie in the peripheral area 34 free from 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 aligning member 21 and the push-in drum 13 is realized here by lifting the aligning member 21 from the push-in 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 Fig. 5 For example, the continuous drawing means 38, which is designed as a toothed belt, is driven by the insertion drum 13, which may 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 pulley 31. In this case, the separate drive of the endless drawing means 21 is expediently synchronized with the drive of the insertion 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 Fig. 5 the traction means 38 is guided so that the insertion drum 13 is arranged inside the loop formed by the traction means 38. In the embodiment according to Fig. 6 the traction means 38 is arranged completely radially outside of the insertion drum 13. In this exemplary embodiment, the traction means 38 has a return strand 40 which moves in the opposite direction to the insertion drum 13. The embodiment according to Fig. 6 can be compared to the embodiment according to Fig. 5 be preferred, since the traction means 38 may be shorter here and occupies 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 Fig. 5 and Fig. 6 are particularly advantageous if, in the transport direction behind the transfer position 17, a suction device 35 is provided which has a over a peripheral portion extending, the alignment member 21 facing suction opening 36. In the alignment member 21 openings 37 are provided, wherein each of a peripheral recess 10 of the insertion drum 13 is associated with an opening 37. During the displacement of the filter rods 6 in the circumferential grooves 10 from the strand-side end 18 to the distal end 19 of the insertion drum 13, the filter rods 6 are braked, for example by means not shown suction openings in the circumferential grooves and finally at the distal end 19 of the insertion drum 13 by applying a negative pressure to the suction opening 36 and thus also to the located in the region of the suction opening 36 openings 37 in the alignment element 21 controlled on the alignment element 21 used. In this embodiment, the aligning element 21, which fits snugly or sealingly against the push-in drum 13, prevents a reduction in the suction power provided by the suction device 35.
