Description

Die Erfindung betrifft eine Einrichtung zum Überführen von pulver- oder granulatförmige Partikel, insbesondere Kohlepartikel, enthaltenden Filterstäben der tabakverarbeitenden Industrie von einer Sendestation zu einer Empfangsstation über eine die Artikel in längsaxialer Aufeinanderfolge transportierende pneumatische Förderleitung, mit einem freie Partikel auffangenden und ableitenden Förderleitungsabschnitt.The invention relates to a device for transferring powder or granular Particles, in particular carbon particles, containing filter rods from the tobacco processing industry Industry from a sending station to a receiving station a pneumatic conveying the articles in a longitudinal axial sequence Delivery line, with a free particle collecting and discharging delivery line section.

Wenn Filterstäbe, die Kohlenstoffgranulat (Charcoal) oder anderes granulatförmiges Filtermaterial enthalten, durch eine pneumatische Transporteinrichtung gefördert werden, geht zwangsläufig ein Teil des Materials aus den Stäben verloren, und es wird dann im losen Zustand als vagabundierende Kohlepartikel durch die Fördereinrichtung bewegt, wobei es die Oberfläche der Filterstäbe verschmutzen kann.If filter rods, the carbon granules (Charcoal) or other granular Filter material included, conveyed by a pneumatic transport device part of the material from the bars is inevitably lost, and it is then in the loose state as stray carbon particles by the conveyor moves, whereby it can contaminate the surface of the filter rods.

Anordnungen der eingangs bezeichneten Gattung, welche mittels eines mit einer unterseitigen Öffnung versehenen, gekrümmten Leitungsabschnitts Partikel aus dem Rohrleitungssystem entfernen, sind zum Beispiel in der US-PS 5 556 236 und in der GB-PS 1 410 473 offenbart:Arrangements of the type described in the introduction, which by means of a underside opening provided, curved pipe section particles remove the piping system are, for example, in U.S. Patent 5,556,236 and in GB-PS 1 410 473 discloses:

Der Erfindung liegt die Aufgabe zugrunde, Ablagerungen freier Kohlepartikel in der Überführungsstrecke und damit deren Schleifkontakt mit den längsaxial hindurchgeförderten Filterstäben zu unterbinden.The invention has for its object to deposit free carbon particles in the Transfer line and thus its sliding contact with the conveyed axially To prevent filter rods.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der im Bereich der Sendestation vorgesehene Förderleitungsabschnitt als sich im wesentlichen über 90° in Förderrichtung aufwärts erstreckender Leitungskrümmer ausgebildet ist, dessen Auffangkammer im unteren Bereich durch eine Abdeckung gegen die Druckzone des Förderleitungsabschnitts abgeschottet ist.This object is achieved in that in the area of the transmitter station intended delivery line section than substantially over 90 ° in Conveying direction upward extending elbow is formed, the Collection chamber in the lower area by a cover against the pressure zone of the conveyor line section is sealed off.

Eine die Kohlepartikel zum Auslaßende der Auffangkammer hin einfangende Weiterbildung besteht darin, daß das - bezogen auf die Förderrichtung - stromabwärtige Ende der Abdeckung als gegen die gekrümmte Kammernwand geneigte Fahne ausgebildet ist, wodurch eine entgegen der Förderblasluft gerichtete Abzugsströmung entsteht.A further development trapping the carbon particles towards the outlet end of the collecting chamber is that - based on the direction of conveyance - downstream End of the cover as a flag inclined against the curved chamber wall is formed, whereby a discharge flow directed against the conveying blowing air arises.

Eine optimale Abzugsströmung wird außerdem dadurch begünstigt, daß die Abdekkung insgesamt als gegen die Kammernwand konvex vorgewölbtes Federblech ausgebildet ist.An optimal discharge flow is also favored by the fact that the cover overall as a spring plate convexly convex against the chamber wall is trained.

Um die angesammelten Kohlepartikel ohne Beeinflussung des Förderdruckes aus der Auffangkammer zu entfernen, wird weiterhin vorgeschlagen, daß die Auffangkammer - bezogen auf die Förderrichtung - am stromaufwärtigen Ende mit einer Ablaßschleuse versehen ist. Eine bedarfsweise Öffnung der Ablaßschleuse kann gemäß einer Weiterbildung dadurch bewirkt werden, daß sie zwei eine Schleusenkammer steuernde, handbetätigte Schleusenhähne aufweist. Alternativ kann die Ablaßschleuse eine Schleusenkammer automatisch zeitabhängig steuernde Ventilbetätigungszylinder aufweisen, die in vorbestimmten Zeitabständen für eine Entleerung der Auffangkammer bzw. der Schleusenkammer sorgen. Um in Abhängigkeit vom jeweils geförderten Filtermaterial eine entsprechende Montage oder Demontage des Förderleitungsabschnitts vornehmen zu können, wird außerdem vorgeschlagen, daß der durch den Leitungskrümmer gebildete Förderleitungsabschnitt als bedarfsweise in die Förderleitung integrierbare Ständereinheit ausgebildet ist.Around the accumulated carbon particles without influencing the delivery pressure To remove the catch chamber, it is further proposed that the catch chamber - in relation to the direction of conveyance - at the upstream end with a Drain lock is provided. If necessary, the drainage lock can be opened according to a further development in that they two a lock chamber controlling, manually operated lock valves. Alternatively, the Drain lock a lock chamber automatically actuating valve actuating cylinders have at predetermined time intervals for a Ensure emptying of the collecting chamber or the lock chamber. In order to have a corresponding one depending on the filter material being conveyed To be able to assemble or disassemble the conveyor line section, it is also proposed that the delivery line section formed by the line elbow as a stand unit that can be integrated into the delivery line as required is trained.

Der mit der Erfindung erzielte Vorteil besteht darin, daß bereits frühzeitig aus einem Förderleitungsabschnitt der Förderleitung, in der noch der volle Überführungsdruck wirksam ist, eine vollständige Entfernung von Kohlepartikeln allein durch die hohe-Fliehkraft erreicht wird, wobei bereits abgelöste Partikel auch durch die hohe Strömungsgeschwindigkeit der Förderluft nicht wieder mitgerissen sondern aus einem unteren Sammelraum der Auffangkammer unter Aufrechterhaltung des Förderdrucks ausgeschleust werden. The advantage achieved with the invention is that from an early stage Delivery line section of the delivery line, in which the full transfer pressure is still effective is a complete removal of carbon particles solely by the high centrifugal force is achieved, with detached particles also due to the high flow rate the conveying air is not swept away again but from one lower collecting chamber of the collecting chamber while maintaining the delivery pressure be removed.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is described below with reference to an embodiment shown in the drawing explained in more detail.

Die in Figur 1 dargestellte pneumatische Überführungseinrichtung besteht im wesentlichen aus einer Sendestation 1, einer pneumatischen Förderleitung 2 und einer Empfangsstation 3, wobei als Sende- und Empfangsstation beispielsweise die von der Anmelderin unter der Bezeichnung "FILTROMAT" angebotenen Einrichtungen verwendet werden können.The pneumatic transfer device shown in Figure 1 consists essentially from a transmitting station 1, a pneumatic conveyor line 2 and one Receiving station 3, with as the transmitting and receiving station, for example, that of facilities offered to the applicant under the name "FILTROMAT" can be used.

Die Sendestation 1 weist eine Fördertrommel 4 auf, die mit Aufnahmemulden 6 für Filterstäbe 7 versehen ist. Die mit Saugbohrungen 8 ausgestatteten sowie von Stegen 9 begrenzten Aufnahmemulden 6 verlaufen parallel zur Drehachse einer Antriebswelle 11 der Fördertrommel 4 und sind nach außen, d. h. auf der der Drehachse abgewandten Seite offen. Die Fördertrommel 4 ist kontinuierlich motorisch antreibbar und wirkt mit ihren Aufnahmemulden 6 trommelumfangsseitig in einer oberen Beschickungszone B queraxial mit einem Vorratsbehälter 12 zur Entnahme der Filterstäbe 7 und trommelstirnseitig in einer unteren Abgabezone C längsaxial mit der stationären pneumatischen Förderleitung 2 zusammen, in welche die Filterstäbe 7 zur Weiterleitung an Verarbeitungseinrichtungen mittels Druckluft überführt werden. Zu diesem Zweck ist der Fördertrommel 4 ein im Bereich der Abgabezone C anstellbarer bzw. absenkbarer Dichtklotz 13 zugeordnet, welcher eine der Umfangsfläche der Fördertrommel 4 angepaßte konkave Gegenfläche aufweist. Im angestellten Zustand stützt sich der Dichtklotz 13 auschließlich an seinen beiden Enden mit seiner Gegenfläche dichtend an zwei konzentrisch zur Fördertrommel 4 angeordneten, ortsfesten Stützbuchsen 14 und 16 ab, deren Außenradius dem Radius der Gegenfläche entspricht, jedoch geringfügig kleiner ist als der Außenradius der Fördertrommel 4. Auf diese Weise ergibt sich ein Spiel 17 und damit eine berührungsfreie Anstellung zwischen der durch die Stege 9 gebildeten Trommelumfangsfläche und der Gegenfläche des Dichtklotzes 13.The transmitting station 1 has a conveyor drum 4, which with receiving troughs 6 for Filter rods 7 is provided. The equipped with suction holes 8 and of webs 9 limited receiving troughs 6 run parallel to the axis of rotation of a drive shaft 11 of the conveyor drum 4 and are outward, d. H. on the axis of rotation opposite side open. The conveyor drum 4 is continuously motorized drivable and acts with their recesses 6 drum circumference in one upper loading zone B transverse axially with a storage container 12 for removal the filter rods 7 and drum end in a lower discharge zone C longitudinally axially together with the stationary pneumatic conveyor line 2, into which the filter rods 7 transferred to processing equipment by means of compressed air become. For this purpose, the conveyor drum 4 is in the area of the delivery zone C adjustable or lowerable sealing block 13 associated with one of the peripheral surface the conveyor drum 4 has a matching concave counter surface. Im employee State, the sealing block 13 is supported exclusively at its two ends with its counter surface sealing two concentrically to the conveyor drum 4 arranged, fixed support bushings 14 and 16, the outer radius of which Radius of the counter surface corresponds, but is slightly smaller than the outer radius the conveyor drum 4. In this way there is a game 17 and thus one non-contact employment between the drum peripheral surface formed by the webs 9 and the counter surface of the sealing block 13.

Die Antriebswelle 11 der Fördertrommel 4 ist durch die Stützbuchsen 14, 16 hindurchgeführt und außerhalb der Stützbuchsen auf nicht dargestellte Weise in ortsfesten Gehäusewänden radial spielfrei gelagert. Die Stützbuchsen 14, 16 selbst sind über Zugtraversen 18 fest mit einer nicht dargestellten stationären Montageplatte verbunden, welche außerdem zur Führung des Dichtklotzes 13 bzw. eines diesen stützenden Tragkörpers 15 sowie zur Aufnahme zweier Druckluftkolben 19 für die vertikale Auf- und Abbewegung des Dichtklotzes 13 bzw. dessen Tragkörpers 15 dient. Durch die in vertikaler Richtung erfolgende und geführte Anstellung des Dichtklotzes 13 wird die exakte Einhaltung eines stirnseitigen Entlüftungsspaltes 21 im Bereich der Abgabezone C zwischen der Fördertrommel 4 und der angrenzenden Gegenfläche der Stützbuchse 14 erzielt.The drive shaft 11 of the conveyor drum 4 is guided through the support bushings 14, 16 and outside of the support bushings in a manner not shown in stationary housing walls mounted radially without play. The support bushings 14, 16 themselves are fixed via traverse members 18 with a stationary mounting plate, not shown connected, which also for guiding the sealing block 13 or one this supporting support body 15 and for receiving two compressed air pistons 19 for the vertical up and down movement of the sealing block 13 or its supporting body 15 serves. Due to the vertical and guided employment of the sealing block 13 is the exact observance of an end vent gap 21 in the area of the discharge zone C between the conveyor drum 4 and the adjacent one Counter surface of the support bush 14 achieved.

Zwecks Zuführung von Druckluft in die Aufnahmemulden 6 zum längsaxialen Überführen der Filterstäbe 7 in die Förderleitung 2 weist die Fördertrommel 4 einen Steuerflansch 22 mit einer jeden Aufnahmemulde 6 zugeordneten Steuerstützen 23 auf. Der Tragkörper 15 ist zu diesem Zweck von einer Schußluftbohrung 24 durchsetzt, die in Querrichtung innerhalb eines Dichtringes 26 zwischen Tragkörper 15 und Dichtklotz 13 mit einer mit den Steuerschlitzen 23 der Fördertrommel 4 verbindbaren Querbohrung 27 kommuniziert.For the purpose of supplying compressed air to the receiving troughs 6 for longitudinal axial transfer the filter rods 7 in the conveyor line 2 has the conveyor drum 4 Control flange 22 with a control support 23 assigned to each receiving trough 6 on. For this purpose, the carrying body 15 is penetrated by a shot air bore 24, in the transverse direction within a sealing ring 26 between the supporting body 15 and sealing block 13 with a connectable to the control slots 23 of the conveyor drum 4 Cross bore 27 communicates.

Die beiden Druckluftkolben 17 sind am Ende mit einem den Tragkörper 15 durchdringenden Druckstempel 28 versehen, der mit seiner Stirnseite mittig am Dichtklotz 13 angreift und innerhalb des Tragkörpers 15 mit diesem eine Schleppverbindung 29 bildet, die ein definiertes Radialspiel aufweist. Die der Abgabezone C benachbarte Stützbuchse 14 ist oberhalb ihrer den Dichtklotz 13 kontaktierenden Dichtfläche 31 von einer achsparallelen, mit der Förderleitung 2 fluchtenden Überführungsbohrung 32 durchsetzt. Um die Filterstäbe 7 störungsfrei über die stirnseitig an der Stütz- und Dichtfläche 31 gebildete Kante zu führen, ist vor der Kante eine in Schußrichtung (Pfeil 33) relativ zur Dichtfläche 31 ansteigende Leitrampe 34 für die Filterstäbe 7 in die angrenzende Stütz- und Dichtfläche des Dichtklotzes 13 eingelassen. The two compressed air pistons 17 are at the end with a penetrating body 15 Stamp 28 provided with its end face centered on the sealing block 13 attacks and within the support body 15 with this a towing connection 29 forms, which has a defined radial play. The support bushing 14 adjacent to the delivery zone C is the sealing block above it 13 contacting sealing surface 31 of an axially parallel, with the delivery line 2 aligned transfer hole 32 penetrated. To the filter rods 7 trouble-free over the edge formed on the end face on the support and sealing surface 31 lead, is in front of the edge in the weft direction (arrow 33) relative to the sealing surface 31 rising guide ramp 34 for the filter rods 7 in the adjacent support and sealing surface of the sealing block 13 inserted.

Bezogen auf die Förderrichtung (Pfeil 33) stromab - ist der Fördertrommel 4 ein in die Förderleitung 2 integrierter Förderleitungsabschnitt 36 in Form eines sich im wesentlichen über 90° in Förderrichtung aufwärts erstreckenden Leitungskrümmers 37 gemäß Figur 2 zugeordnet, der als austauschbare Ständereinheit 38 ausgebildet ist.Relative to the conveying direction (arrow 33) downstream - the conveying drum 4 is an in the conveyor line 2 integrated conveyor line section 36 in the form of a substantially elbow extending upward over 90 ° in the conveying direction 37 assigned according to Figure 2, which is designed as an interchangeable stand unit 38 is.

Im Bereich des Leitungskrümmers 37 weist die Förderleitung 2 unterseitig einen entsprechend gekrümmten zentralen Führungssteg 39 für die Filterstäbe 7 auf, welcher beidseitig eine Verbindung zu einer sich unterhalb der Förderleitung 2 erstreckenden Auffangkammer 41 für vagabundierende Kohlepartikel freiläßt. Die Auffangkammer 41 ist im unteren Krümmungsabschnitt des Leitungskrümmers 37 durch eine als Federblech 42 ausgebildete Abdeckung 43 gegen die Druckzone der Förderleitung 2 abgeschottet. Das freie stromabwärtige Ende des insgesamt gegen die Kammerwand konvex vorgewölbten Federbleches 42 ist als gegen die gekrümmte Kammerwand geneigte Fahne 44 ausgebildet.In the area of the line elbow 37, the delivery line 2 has one on the underside correspondingly curved central guide web 39 for the filter rods 7, which is connected on both sides to a extending below the conveyor line 2 Collection chamber 41 for stray carbon particles leaves free. The Collecting chamber 41 is in the lower bend section of the line bend 37 by a cover 43 designed as a spring plate 42 against the pressure zone of the Delivery line 2 is sealed off. The free downstream end of the total against the chamber wall is convexly pre-curved spring plate 42 as against the curved Chamber wall inclined flag 44 formed.

Am unteren stromaufwärtigen Ende ist die Auffangkammer 41 mit einer Ablaßschleuse 46 ausgestattet, die gemäß Figur 2 mit zwei eine Schleusenkammer 47 steuernden, handbetätigten Schleusenhähnen 48 und 49 versehen ist. Alternativ ist die Schleusenkammer 47 gemäß Figur 5 automatisch und zeitabhängig durch zwei Ventilbetätigungszylinder 50, 51 steuerbar.At the lower upstream end is the collecting chamber 41 with a drainage lock 46 equipped with two a lock chamber 47 according to FIG controlling, manually operated lock valves 48 and 49 is provided. Alternatively, the lock chamber 47 according to FIG. 5 is automatic and time-dependent controllable by two valve actuating cylinders 50, 51.

Die Wirkungsweise der Überführungseinrichtung ist wie folgt:The transfer device works as follows:

Zur Inbetriebnahme wird der Dichtklotz 13 aus seiner nicht dargestellten, beispielsweise aus Reinigungsgründen abgesenkten Position in die in der Figur 1 dargestellte Betriebspositionen bewegt, in der die Bewegungsfreiheit der Druckstempel 28 relativ zum Tragkörper 15 bzw. das Spiel in der Schleppverbindung in Anstellrichtung so bemessen ist, daß unter praktisch schwimmender und dichtender Anlage des Dichtklotzes 13 an den Stützbuchsen 14, 16 der Dichtring 26 zwischen dem Tragkörper 15 und dem Dichtklotz 13 unter Vorspannung anliegt, wobei die Zugtraversen 18 die auf die Stützbuchsen 14 und 16 ausgeübten Druck- und Biegekräfte auffangen und das System in sich verspannen. Hingegen verbleibt wegen des geringeren Trommeldurchmessers der Fördertrommel 4 ein definiertes Spiel 17 zwischen der Umfangsfläche der Fördertrommel 4 und dem Dichtklotz 13, so daß ein reibungs- und damit verschleißfreier Betrieb möglich ist.For commissioning, the sealing block 13 is removed from its, not shown, for example lowered position for cleaning reasons in the shown in Figure 1 Operating positions moves in the freedom of movement of the pressure stamp 28 relative to the support body 15 or the play in the towing connection in the direction of attack is so dimensioned that under practically floating and sealing System of the sealing block 13 on the support bushings 14, 16 of the sealing ring 26 between the support body 15 and the sealing block 13 rests under tension, the Zugtraversen 18 the pressure and bending forces exerted on the support bushings 14 and 16 catch and tension the system in itself. On the other hand, remains because the smaller drum diameter of the conveyor drum 4 a defined game 17th between the peripheral surface of the conveyor drum 4 and the sealing block 13, so that smooth and wear-free operation is possible.

Während des Betriebes übernimmt die über die Antriebswelle 1 mit konstanter Drehzahl angetriebene Fördertrommel 4 in der Beschickungszone B in ihre Aufnahmemulden 6 Filterstäbe 7 aus dem im Vorratsbehälter 12 über der Fördertrommel 4 befindlichen Vorrat von Filterstäben. Die Filterstäbe 7 werden in den Aufnahmemulden 6 von der Fördertrommel 4 aus der Beschickungszone B in die Abgabezone C überführt, in der die Filterstäbe axial direkt aus den Aufnahmemulden 6 in die pneumatische Förderleitung 2 während der Drehung der Fördertrommel 4 bewegt werden sollen. Fluchtet eine Aufnahmemulde 6 mit der pneumatischen Förderleitung 2 bzw. mit der Überführungsbohrung 32 in der Stützbuchse 14, dann kann Druckluft über die Bohrung 24 im Tragkörper 15, die Querbohrung 27 im Dichtklotz 13 sowie über einen zugeordneten Steuerschlitz 23 in die Aufnahmemulde 6 strömen, den darin befindlichen Filterstab 7 in Richtung des Pfeils 33 axial bewegen und ihn über die als Sprungschanze wirkende Leitrampe 34 in die Förderleitung 2 überführen.During operation it takes over the drive shaft 1 with constant Speed driven conveyor drum 4 in the loading zone B in its receiving troughs 6 filter rods 7 from the in the reservoir 12 above the conveyor drum 4 located supply of filter rods. The filter rods 7 are in the receiving troughs 6 from the conveyor drum 4 from the loading zone B into the delivery zone C transferred in which the filter rods axially directly from the receiving troughs 6 in the pneumatic conveyor line 2 moves during the rotation of the conveyor drum 4 should be. Aligns a receiving trough 6 with the pneumatic delivery line 2 or with the transfer bore 32 in the support bush 14, then can Compressed air via the bore 24 in the support body 15, the transverse bore 27 in the sealing block 13 and flow into the receiving trough 6 via an associated control slot 23, move the filter rod 7 located therein axially in the direction of arrow 33 and into the delivery line 2 via the guide ramp 34 which acts as a ski jump convict.

Durch den Überführungsvorgang mit seinen auf die Filterstäbe einwirkenden Richtungsänderungen (Querrichtung, Längsrichtung) sowie Beschleunigungen und Verzögerungen werden aus Abschnitten der Filterstäbe 7, die Kohlegranulat (Charcoal) enthalten, Kohlepartikel herausgelöst, welche als vagabundierende Partikel die Förderleitung 2 belasten, dabei Verfärbungen der Filterstäbe verursachen und rechtzeitig entfernt werden müssen.Through the transfer process with its changes in direction acting on the filter rods (Transverse direction, longitudinal direction) as well as accelerations and decelerations sections of the filter rods 7, the carbon granules (Charcoal) contain, released carbon particles, which as vagabonding particles Load delivery line 2, causing discoloration of the filter rods and must be removed in time.

Dies geschieht im Bereich des unmittelbar anschließenden Leitungskrümmers 37, in welchem derartige Partikel infolge der entlang des 90°-Bogens wirksamen Fliehkraft aus der Förderleitung 2 in die Auffangkammer 41 katapultiert und durch die Abdeckung 43 nicht nur daran gehindert werden, in den Förderluftstrom zurückzufliegen sondern durch den Strömungseffekt der Fahne 44 sogar aus der Förderleitung 2 in die Auffangkammer 41 hineingezogen werden.This takes place in the area of the immediately adjacent line elbow 37, in which such particles due to the effective along the 90 ° arc Centrifugal force from the delivery line 2 catapulted into the collecting chamber 41 and through the cover 43 is not only prevented from flying back into the conveying air flow but by the flow effect of the flag 44 even from the delivery line 2 are drawn into the collecting chamber 41.

Die sich am unteren Ende der Auffangkammer 41 ansammelnden Kohlepartikel werden bedarfsweise durch Öffnen des Schleusenhahns 48 in die Schleusenkammer 47 überführt und nach Schließen des Schleusenhahns 48 und Öffnen des Schleusenhahns 49 aus der Schleusenkammer 47 entsorgt, so daß der Förderdruck in der Förderleitung 2 unvermindert wirksam bleibt.The coal particles collecting at the lower end of the collecting chamber 41 are opened by opening the lock valve 48 into the lock chamber 47 transferred and after closing the lock valve 48 and opening the Lock valve 49 disposed of from the lock chamber 47, so that the delivery pressure remains unabated in the delivery line 2.
