DEUTSCHESGERMAN

Die Erfindung bezieht sich auf eine Tabakzerkleinerungs- und -Sortieranlage mit einem Zufuhrförderband für die Tabakblätter, einer Zerkleinerungsvorrichtung, einer Abscheidekammer für das Trennen der zerkleinerten Tabakblatteile von den blattfreien Rippen, einer Tabaksetzkammer für das Ausscheiden der Tabakblatteile aus einem Sichtluftstrom, einem die Abscheidekammer und die Absetzkammer verbindenden Kanal und einem den Luftstrom an der Tabakzerkleinerungsvorrichtung vorbei durch die Abscheidekammer, den Kanal und die Absetzkammer fördernden Gebläse.The invention relates to a tobacco shredding and sorting system with a feed conveyor belt for the tobacco leaves, a shredding device, a separation chamber for separating the shredded Tobacco leaf parts from the leafless ribs, a tobacco setting chamber for the excretion of the Tobacco leaf parts from a stream of classifying air, one connecting the separation chamber and the settling chamber Channel and the air flow past the tobacco shredding device through the separation chamber, fans conveying the duct and the settling chamber.

Aufgabe der Erfindung ist die Ausgestaltung und Anordnung einer solchen Anlage, derart, daß der Platzbedarf gegenüber den bekannten Anlagen sich beträchtlich vermindert, trotzdem aber eine große Durchsatzleistung und eine einwandfreie Bearbeitung des Tabaks gesichert sind.The object of the invention is the design and arrangement of such a system such that the Space requirement compared to the known systems is considerably reduced, but still a large one Throughput and proper processing of the tobacco are assured.

Erfindungsgemäß wird dies dadurch erreicht, daß der Tabak der Anlage quer zu deren Längsrichtung an einer Stelle zwischen der Abscheidekammer und der Absetzkammer zugeführt wird.According to the invention this is achieved in that the tobacco of the plant transversely to its longitudinal direction is fed at a point between the separation chamber and the settling chamber.

Weitere Merkmale der erfindungsgemäß ausgebildeten Anlage haben die Regelung der Speisung mit Tabakblättern und die Vermeidung eines Staubaustritts in den Arbeitsraum zum Ziel.Further features of the system designed according to the invention include the regulation of the supply Tobacco leaves and the avoidance of dust escaping into the work area are the goal.

Die Zeichnung zeigt ein Ausführungsbeispiel einer Anlage gemäß der Erfindung, und zwar zeigtThe drawing shows an embodiment of a system according to the invention, namely shows

Fig. 1 einen Längsschnitt durch die Anlage,Fig. 1 is a longitudinal section through the system,

Fig. 2 einen Schnitt nach der Linie 2-2 in Fig. 2 undFig. 2 shows a section along the line 2-2 in Fig. 2 and

Fig. 3 eine Stirnansicht der Anlage in einem Schnitt nach der Linie 3-3 in Fig. 2.FIG. 3 shows an end view of the system in a section along the line 3-3 in FIG. 2.

Die zu entrippenden Tabakblätter werden auf ein geneigtes endloses Zufuhrförderband 10 einer selbsttätigen Querzuführung C aufgelegt, die so eingerichtet ist, daß der Maschine ununterbrochen eine bestimmte Menge Tabakblätter zugeführt wird. Der überschüssige, nicht in der Maschine benutzte Tabak wird in die Ouerzuführung der nächsten Maschine entladen, in welcher wieder eine bestimmte Menge Tabak entnommen und der verbleibende Überschuß in die Querzuführung der nächstfolgenden Maschine entladen wird.The tobacco leaves to be stripped are placed on an inclined, endless feed conveyor belt 10 of an automatic transverse feeder C , which is set up so that a certain amount of tobacco leaves is continuously fed to the machine. The excess tobacco not used in the machine is discharged into the overfeed of the next machine, in which again a certain amount of tobacco is removed and the remaining excess is discharged into the cross feed of the next machine.

Das geneigte Zufuhrförderband 10 wird ununterbrochen angetrieben und ist von einem Trog 12 umgeben, welcher an seinem oberen Ende mit einer öffnung 14 versehen ist, so^ daß die durch das Förderband in Richtung des Pfeiles (Fig. 2) geförderten Tabakblätter auf eine Leitvorrichtung in Form eines Führungsbleches 16 fallen, das mit einer Umlenkhaube H verbunden ist. Die Umlenkhaube H besteht aus zwei in Abstand voneinander angeordneten halbkreisförmigen Seitenwänden 18, deren gekrümmte Tabakzerkleinerungs- und -SortieranlageThe inclined supply conveyor belt 10 is continuously driven and is surrounded by a trough 12, which is provided at its upper end with an opening 14 so that the tobacco leaves conveyed by the conveyor belt in the direction of the arrow (FIG. 2) on a guide device in the form a guide plate 16, which is connected to a deflection hood H fall. The deflection hood H consists of two spaced apart semicircular side walls 18, their curved tobacco shredding and sorting system

Kanten durch eine gebogene Abdeckplatte 20 in Veras bindung stehen. Jede Seitenwand 18 ist durch Lagerringe oder Hülsen 22 gelagert, welche auf den Umfang von zwei Lagergehäusen 24 drehbar sind. Die beiden Lagergehäuse 24 dienen zur Lagerung einer Welle 26, auf der eine Rolle 28 befestigt ist. Die Rolle 28 dient zur Auflagerung des oberen Endes des Zufuhrförderbandes 10.Edges are linked by a curved cover plate 20 in Veras. Each side wall 18 is supported by bearing rings or sleeves 22, which are rotatable on the circumference of two bearing housings 24. The two Bearing housings 24 serve to support a shaft 26 on which a roller 28 is fastened. The role 28 is used for supporting the upper end of the feed conveyor belt 10.

Das untere Ende des Zufuhrförderbandes 10 liegt auf einer Rolle 30 auf, die sich auf einer Welle 32 befindet, welche in Lagern in den Seitenwänden des Troges 12 gelagert ist. An der Nabe einer der Seitenwände 18 der Umlenkhaube H ist ein Arm 34 (Fig. 2) befestigt, der mittels eines Gliedes 36 mit dem einen Ende eines doppelarmigen Hebels 38 verbunden ist. In der Mitte des Hebels 38 befindet sich ein Drehzapfen 40, der von einer der Seitenwände der Haube H getragen wird. Das andere Ende des doppelarmigen Hebels 38 ist mit dem einen Ende eines senkrechten Betätigungshebels 42 verbunden, dessen unteres freies Ende einen Handgriff 44 trägt.The lower end of the supply conveyor belt 10 rests on a roller 30 which is located on a shaft 32 which is mounted in bearings in the side walls of the trough 12. An arm 34 (FIG. 2) is attached to the hub of one of the side walls 18 of the deflection hood H and is connected to one end of a double-armed lever 38 by means of a link 36. In the center of the lever 38 is a pivot 40 which is carried by one of the side walls of the hood H. The other end of the double-armed lever 38 is connected to one end of a vertical actuating lever 42, the lower free end of which carries a handle 44.

Eine der Seitenkanten des Betätigungshebels 42 ist mit einer Vielzahl von Zähnen 46 versehen, von denen einer, je nach der gewünschten Einstellung, mit einer Klinke 48 im Eingriff steht, die um einen Bolzen 50 schwenkbar ist. Der Bolzen 50 wird von einer Stütze 52 getragen, welche am Hauptgestell der Maschine befestigt ist. Mit der Klinke 48 ist ein Auslösehebel 54 fest verbunden, der von der Klinke absteht, wobei das freie Ende des Auslösehebels 54 mit einer Verlängerung 56 des Ankers eines Solenoids 58 verbunden ist, One of the side edges of the operating lever 42 is provided with a plurality of teeth 46, of which one, depending on the desired setting, engages a pawl 48 which is engaged around a bolt 50 is pivotable. The bolt 50 is carried by a support 52 which is attached to the main frame of the machine is attached. A release lever 54 is fixedly connected to the pawl 48 and protrudes from the pawl the free end of the release lever 54 is connected to an extension 56 of the armature of a solenoid 58,

If too much air flows through the machine axis continuously rotating cellular wheel 62, this can according to the invention simply be changed by changing the tobacco leaves L through the belt so that more tobacco is fed. Near the top of this will be. The belt 86 flings the leaf parts and tobacco sluice is another inclined and uninterrupted rib parts arranged against a wall 88 of the housing D and broken driven conveyor belt 64, which is in an air stream, which is provided in the separator housing with two side walls 66, which more the position A occurs.
