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 dieses Material auch die Empfangsstation erreicht, deren Arbeitsweise es irgendwann beeinträchtigen kann.
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.When filter rods containing carbon granules (Charcoal) or other granular filter material are conveyed by a pneumatic transport device, part of the material is inevitably lost from the rods and is then moved in the loose state as vagrant carbon particles through the conveyor, this material has also reached the receiving station, the operation of which may at some point affect it.
Arrangements of the type described in the introduction, which remove particles from the pipeline system by means of a curved line section provided with an underside opening, are disclosed, for example, in US Pat. No. 5,556,236 and in GB Pat. No. 1,410,473.

Der Erfindung liegt die Aufgabe zugrunde, freie Kohlepartikel unabhängig von der jeweiligen Förderleistung der pneumatischen Förderleitung auf effektive Weise möglichst vollständig und rechtzeitig vor dem Eintritt in verschmutzungsgefährdete Förderaggregate zu entfernen.The invention is based, free carbon particles independent of the task delivery capacity of the pneumatic delivery line in an effective manner as completely as possible and in good time before entering pollution-prone areas Remove conveyor units.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der im Bereich der Empfangsstation vorgesehene Förderleitungsabsohnitt durch im wesentlichen querverlaufende Schlitze unterbrochen ist, in welche auf eine Aufgangkammer ausgerichtete Blasluftkanäle einmünden.
Eine möglichst vollständige Beseitigung der am Umfang der Filterstäbe haftenden Kohlepartikel wird gemäß einer vorteilhaften Ausgestaltung dadurch erzielt, daß der Förderleitungsabschnitt durch als Radialschlitze ausgebildete Schlitze getrennte Förderleitungssegmente aufweist.
Zweckmäßigerweise zweigen die Blasluftkanäle von einer gemeinsamen, parallel zum Förderleitungsabschnitt verlaufenden Blasluftzuleitung ab.
Nach einem weiteren Vorschlag wird die Austragung der in der Auffangkammer gesammelten Partikel dadurch vereinfacht und erleichtert, daß der Förderieitungsabschnitt - bezogen auf die Förderrichtung von oben nach unten - im wesentlichen vertikal verlaufend mit einer unterseitigen Auslaßöffnung der Auffangkammer angeordnet ist.According to the invention, this object is achieved in that the delivery line section provided in the area of the receiving station is interrupted by essentially transverse slots into which blown air channels aligned with a rising chamber open.
The most complete possible removal of the carbon particles adhering to the circumference of the filter rods is achieved according to an advantageous embodiment in that the delivery line section has separate delivery line segments formed by slots formed as radial slots.
The blown air ducts expediently branch off from a common blown air supply line running parallel to the conveying line section.
According to a further proposal, the discharge of the particles collected in the collecting chamber is simplified and facilitated in that the conveying line section - with respect to the conveying direction from top to bottom - is arranged to run essentially vertically with an outlet opening on the underside of the collecting chamber.

Der mit der Erfindung erzielte Vorteil besteht darin, daß sowohl bei niedrigen als auch bei hohen Fördergeschwindigkeiten der Filterstäbe die diese quer umströmende Blasluft alle anhaftenden Partikel erfaßt und abträgt, wobei die Partikel aus der in diesem Förderleitungsabschnitt praktisch drucklosen Auffangkammer ohne weiteres nach unten ausgetragen werden können. The advantage achieved by the invention is that both at low and even at high conveyor speeds of the filter rods that flow transversely Blown air detects and removes all adhering particles, the particles from the virtually unpressurized collecting chamber in this conveyor line section without more can be carried down.

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.

Hierbei zeigen:

Here show:
Figure 1
a conveyor for the transport of filter rods with a transmitting station and a receiving station shown in section and
Figure 2
a cut-off chamber for carbon particles integrated into the conveyor.

Die Fördereinrichtung der Figur 1 besteht im wesentlichen aus einer Sendestation 1, einer pneumatischen Förderleitung 2 und einer Empfangsstation 3, sowie einem der Empfangsstation 3 vorgeordneten Bremsmittel 4 zum Reduzieren der Fördergeschwindigkeit von durch die Förderleitung geförderten Filterstäben 6 und einem Beschleunigungsmittel 7 zum vereinzelten Zuführen der Filterstäbe 6 zu der Empfangsstation 3.
Als Sende- und Empfangsstation können beispielsweise die von der Anmelderin unter der Bezeichnung "FILTROMAT" angebotenen Einrichtungen verwendet werden. Zwischen dem Bremsmittel 4 und dem Beschleunigungsmittel 7 ist eine U-förmige gekrümmte Führung 8 angeordnet, deren offene Seite durch ein flexibles Federblech 9 abgedeckt ist. Mit einer derartigen Führung 8 kann die Förderrichtung der Filterstäbe 6 auf engstem Raum geändert werden.
Das Bremsmittel 4 und das Beschleunigungsmittel 7 sind identisch in ihrem Aufbau und werden im folgenden gemeinsam beschrieben.
Die Bezugszeichen für das Bremsmittel 4 sind mit dem Index a versehen und die für das Beschleunigungsmittel 7 weisen den Index b auf. Das Bremsmittel 4 (Beschleunigungsmittel 7) besteht aus vier Rollen 11a, 12a, 13a, 14a (11b, 12b, 13b, 14b), von denen je zwei Rollen 11a, 12a (11b, 12b) bzw. 13a, 14a (13b, 14b) in Förderrichtung (Pfeil 16) der Filterstäbe 6 hintereinander angeordnet sind und von als Mittel zum Übertragen der Bremskraft (Beschleunigungskraft) auf die Filterstäbe 6 ausgebildeten endlosen Riemen 17a (17b) bzw. 18a (18b) umschlungen werden. Die Abstände der Rollen 11a und 13a (11b und 13b) bzw. 12a und 14a (12b und 14b) zueinander sind so gewählt, daß die Riemen 17a, 18a die Filterstäbe 6 einerseits fest packen, sie aber andererseits nicht zu sehr verformen. Die Rollen 11a und 13a (11b und 13b) sind über einen Riementrieb 19a (19b) und ein die Rollen 11a und 13a (11b und 13b) verbindendes Zahnradpaar 21a, 22a (21b, 22b) von einem Motor 23 antreibbar, wobei die Rollen 12a bzw. 14a (12b bzw. 14b) über die Riemen 17a (17b) bzw. 18a (18b) mit antreibbar sind. Hierbei werden die die Filterstäbe 6 fassenden Trume der Riemen 17a, 18a (17b, 18b) in Förderrichtung (Pfeil 16) der Filterstäbe 6 bewegt. Die Riementriebe 19a und 19b sind derart ausgelegt, daß die Rollen 11b und 13b des Beschleunigungsmittels 7 mit größerer Umfangsgeschwindigkeit als die Rollen 11a und 13a des Bremsmittels 4 antreibbar sind.
Die Entnahmestation 3 weist einen Förderer in Form zweier endloser paralleler Bänder 24 auf, von denen nur das hintere dargestellt ist, welche zum Bewegen der Filterstäbe 6 in queraxialer Richtung in einen nicht dargestellten Speicher, beispielsweise den Speicher einer Filteransetzmaschine, dienen. Die Förderbänder 24 sind um Walzen 26, 27 geführt, wobei die Walze 27 über ein Zahnradpaar 28 auch die entsprechende Gegenwalze über einen Zahnriemenantrieb 29 von einem nicht dargestellten Motor antreibbar sind. Eine zwischen dem Walzenpaar 26 und dem Beschleunigungsmittel 7 angeordnete Führungsfläche 31 für die aus der Förderleitung 2 austretenden Filterstäbe 6 weist einen Führungskeil 32 zum Anheben der voreilenden Enden der Filterstäbe 6 auf, so daß diese von den mittleren Trumen der paarweisen Bänder 24 erfaßt werden können.The conveying device of FIG. 1 essentially consists of a transmitting station 1, a pneumatic conveying line 2 and a receiving station 3, as well as a braking means 4 arranged upstream of the receiving station 3 for reducing the conveying speed of filter rods 6 conveyed by the conveying line and an accelerating means 7 for the individual feeding of the filter rods 6 to the receiving station 3.
For example, the devices offered by the applicant under the name "FILTROMAT" can be used as the transmitting and receiving station. A U-shaped curved guide 8 is arranged between the braking means 4 and the acceleration means 7, the open side of which is covered by a flexible spring plate 9. With a guide 8 of this type, the conveying direction of the filter rods 6 can be changed in a very small space.
The brake means 4 and the acceleration means 7 are identical in their construction and are described together below.
The reference symbols for the braking means 4 are provided with the index a and those for the acceleration means 7 have the index b . The braking means 4 (acceleration means 7) consists of four rollers 11a, 12a, 13a, 14a (11b, 12b, 13b, 14b), of which two rollers 11a, 12a (11b, 12b) and 13a, 14a (13b, 14b) ) are arranged one behind the other in the conveying direction (arrow 16) of the filter rods 6 and are looped around by endless belts 17a (17b) or 18a (18b) designed as means for transmitting the braking force (acceleration force) to the filter rods 6. The distances between the rollers 11a and 13a (11b and 13b) or 12a and 14a (12b and 14b) are selected so that the belts 17a, 18a firmly grip the filter rods 6 on the one hand, but do not deform them too much on the other hand. The rollers 11a and 13a (11b and 13b) can be driven by a motor 23 via a belt drive 19a (19b) and a pair of gears 21a, 22a (21b, 22b) connecting the rollers 11a and 13a (11b and 13b), the rollers 12a or 14a (12b or 14b) can also be driven via the belts 17a (17b) or 18a (18b). Here, the strands of the belts 17a, 18a (17b, 18b) holding the filter rods 6 are moved in the conveying direction (arrow 16) of the filter rods 6. The belt drives 19a and 19b are designed such that the rollers 11b and 13b of the accelerating means 7 can be driven at a greater peripheral speed than the rollers 11a and 13a of the braking means 4.
The removal station 3 has a conveyor in the form of two endless parallel belts 24, of which only the rear one is shown, which are used to move the filter rods 6 in the transverse axial direction into a memory (not shown), for example the memory of a filter attachment machine. The conveyor belts 24 are guided around rollers 26, 27, wherein the roller 27 can also be driven by a motor, not shown, via a pair of gearwheels 28 and the corresponding counter-roller via a toothed belt drive 29. A arranged between the pair of rollers 26 and the accelerating means 7 guide surface 31 for the filter rods 6 emerging from the conveying line 2 has a guide wedge 32 for lifting the leading ends of the filter rods 6 so that they can be gripped by the central strands of the pairs of belts 24.

Im Bereich der Empfangsstation 3, d. h.- bezogen auf die Förderrichtung (Pfeil 16) - stromauf der Empfangsstation ist in die pneumatische Förderleitung 2 ein von einer Auffangkammer 33 umschlossener Förderleitungsabschnitt 34 installiert, welcher gemäß Figur 2 durch querverlaufende Radialschlitze 36 in hintereinandergereihte Förderleitungssegmente 37 unterteilt ist. In die Radialschlitze 36 münden Blasluftkanäle 38, welche auf die gegenüberliegende Kammernwand der umschließenden Auffangkammer 33 ausgerichet sind und von einer gemeinsamen, parallel zum Förderleitungsabschnitt 34 verlaufenden Blasluftzuleitung 39 abzweigen. Die Blasluftzuleitung 39 ist mit einem Blasluftanschluß 41 und die Auffangkammer 33 mit einem Ablaßstutzen 42 für Kohlepartikel 43 ausgestattet. In the area of the receiving station 3, d. h.- related to the direction of conveyance (arrow 16) - upstream of the receiving station in the pneumatic conveyor line 2 is one of a containment chamber 33 enclosed conveyor line section 34 installed as shown in Figure 2 by transverse radial slots 36 in a row Delivery line segments 37 is divided. Open into the radial slots 36 Blown air channels 38, which on the opposite chamber wall of the enclosing Collection chamber 33 are aligned and of a common, parallel branch off to the delivery line section 34 extending blown air supply line 39. The Blown air supply line 39 has a blown air connection 41 and the collecting chamber 33 equipped with a drain port 42 for carbon particles 43.

Die Wirkungsweise der Vorrichtung gemäß den Figuren 1 und 2 ist wie folgt:The mode of operation of the device according to FIGS. 1 and 2 is as follows:

Filterstäbe 6 werden von der Sendestation 1 durch die pneumatische Förderleitung 2 zu dem Bremsmittel 4 gefördert.
Beim Passieren der Auffangkammer 33 im Förderleitungsabschnitt 34 erfaßt die Querluftströmung in den Radialschlitzen 36 freie bzw. aus den Filterstäben 6 herausgelöste Kohlepartikel 43 und wirft sie in Richtung der gegenüberliegenden Kammernwand der Auffangkammer 33, wo sie zu Boden sinken und über den Ablaßstutzen 42 entfernt werden.
Die von vagabundierenden Kohlepartikeln 43 befreiten Filterstäbe 6 werden von den Riemen 17a, 18a kraftschlüssig erfaßt und abgebremst. Hierdurch bildet sich vor dem Bremsmittel 4 ein Rückstau an Filterstäben 6, wobei ein nicht unerheblicher Druck auf den zwischen den Riemen 17a, 18a gehaltenen Filterstab 6 ausgeübt wird. Weil aber der betreffende Filterstab 6 praktisch über seine gesamte Länge von den Riemen 17a, 18a geführt wird, kann er, ohne daß er übermäßig verformt wird, schlupflos gehalten und auf eine definierte Geschwindigkeit abgebremst werden. Der Führungsbereich des Bremsmittels 4 muß jedoch nicht unbedingt der gesamten Länge eines Filterstabes entsprechen, sondern er kann je nach Länge der zu verarbeitenden Filterstäbe, auch kürzer oder länger sein. Nach ihrem Abbremsen rutschen die Filterstäbe durch die gekrümmte Führung 8 und werden von den Riemen 17b, 18b des Beschleunigungsmittels 7 kraftschlüssig erfaßt und beschleunigt zur Empfangsstation 3 gefördert. Hierdurch wird sichergesellt, daß die Filterstäbe 6 in jedem Fall jeweils von einem nachfolgenden Filterstab 6 räumlich getrennt werden. Die Filterstäbe 6 rutschen über die Führungsfläche 31 auf den Führungskeil 32 und werden hierbei angehoben, so daß sie von den Bändern 24 erfaßt und aufwärts transportiert werden.Filter rods 6 are conveyed from the transmitting station 1 through the pneumatic delivery line 2 to the braking means 4.
When passing through the collecting chamber 33 in the conveying line section 34, the transverse air flow in the radial slots 36 detects free or detached carbon particles 43 or detached from the filter rods 6 and throws them in the direction of the opposite chamber wall of the collecting chamber 33, where they sink to the bottom and are removed via the outlet connection 42.
The filter rods 6 freed from stray carbon particles 43 are non-positively gripped and braked by the belts 17a, 18a. As a result, a backlog of filter rods 6 forms in front of the braking means 4, a not inconsiderable pressure being exerted on the filter rod 6 held between the belts 17a, 18a. However, because the filter rod 6 in question is guided by the belts 17a, 18a practically over its entire length, it can be held without slippage without being excessively deformed and braked to a defined speed. However, the guide area of the braking means 4 does not necessarily have to correspond to the entire length of a filter rod, but it can also be shorter or longer, depending on the length of the filter rods to be processed. After braking, the filter rods slide through the curved guide 8 and are non-positively gripped by the belts 17b, 18b of the accelerating means 7 and conveyed to the receiving station 3 in an accelerated manner. This ensures that the filter rods 6 are in each case spatially separated from a subsequent filter rod 6. The filter rods 6 slide over the guide surface 31 onto the guide wedge 32 and are thereby raised so that they are gripped by the belts 24 and transported upwards.
