Description

Die Erfindung befaßt sich mit einem Sichtmittel zum Sichten eines Produktstroms innerhalb einer Verteilervorrichtung zum Beschicken einer Zigarettenstrangmaschine, wobei das Sichtmittel als im wesentlichen vertikal ausgerichteter Zick-Zack-Sichter ausgebildet ist und einen eine Sichtstrecke bildenden, geteilten Sichtraum mit mindestens einem Zugang für den innerhalb der Sichtstrecke zu sichtenden Produktstrom aufweist, vgl. US-A-4 931 174 .The invention relates to a sighting means for sifting a product stream within a dispensing apparatus for feeding a cigarette rod making machine, wherein the vision means is formed as a substantially vertically oriented zigzag sifter and forming a sight line, divided viewing space with at least one access for inside the Viewing line to be seen product flow, see. US-A-4,931,174 ,

Der Produktstrom wird innerhalb der Verteilervorrichtung aus einem Reservoir mittels eines Förderelementes, vorzugsweise einem Steilförderer, dem Sichtmittel zugeführt. Der gesichtete Produktstrom wird dann über eine Transportstrecke in einen Stauschacht weiter geleitet. Das Sichtmittel ist demnach innerhalb der Verteilervorrichtung in Transportrichtung des Produktstroms dem Stauschacht vorgeschaltet. Bekannte Sichtmittel dieser Art weisen einen Sichtraum auf, in dem zu verarbeitende Anteile von nicht zu verarbeitenden Anteilen des Produktstroms mittels einer Luftströmung getrennt werden. Der Produktstrom ist aus einzelnen Tabakportionen gebildet, die im Bereich eines Zugangs in das Sichtmittel gegeben werden. Durch die Luftströmung innerhalb des Sichtmittels, also in der durch den Sichtraum definierten Sichtstrecke werden die Tabakportionen unkontrolliert auseinandergezogen, was zu einer ungleichmäßigen Verteilung des Produktstroms über die Breite des Sichtraumes bzw. der Sichtstrecke führt. Durch die über die Breite ungleichmäßige Zuführung des Produktstroms an den Stauschacht ist auch die Befüllung des Stauschachtes selbst über die Breite ungleichmäßig. Eine solche ungleichmäßige Befüllung kann wiederum zu einer Störung bei der Bildung eines Tabakstranges in der nachgeordneten Zigarettenstrangmaschine führen.The product stream is supplied within the distributor device from a reservoir by means of a conveying element, preferably a vertical conveyor, to the viewing means. The screened product stream is then passed on a transport route in a stowage night. The viewing means is therefore preceded by the delivery tube within the distributor device in the transport direction of the product stream. Known sight of this type have a viewing space in which to be processed portions of unprocessed portions of the product stream are separated by an air flow. The product stream is formed from individual tobacco portions, which are added in the area of an access into the visual means. Due to the air flow within the viewing means, ie in the sight line defined by the viewing area, the tobacco portions are pulled apart in an uncontrolled manner, which leads to an uneven distribution of the product flow across the width of the viewing space or the sighting line. Due to the uneven across the width supply of the product flow to the stowage even the filling of the stowage even over the width is uneven. Such an uneven filling can in turn lead to a disruption in the formation of a tobacco rod in the downstream cigarette rod machine.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Sichtmittel zu schaffen, daß mit einfachen Mitteln eine gleichmäßige Befüllung des Stauschachtes ermöglicht, insbesondere dann, wenn das Sichtmittel dem Stauschacht in Transportrichtung des Produktstroms vorgeschaltet ist.It is therefore an object of the present invention to provide a visual means that allows a simple filling of the Steschachtes with simple means, especially if the view means is upstream of the stowage in the transport direction of the product stream.

Diese Aufgabe wird mit dem Gegenstand des Anspruchs 1 gelöst insbesondere dadurch, daß der Sichtraum durch Trennwände in Kammern geteilt ist, wobei jede Trennwand durchbrochen ist. Durch die Unterteilung des Sichtraumes ist eine gleichmäßige Verteilung des Produktstromes bzw. der Tabakportionen über die Breite des Sichtmittels bzw. des Sichtraumes wesentlich vereinfacht, da die Luftströmung innerhalb des Sichtraumes den Produktstrom bzw. die Tabakportionen nur noch begrenzt auseinanderziehen kann, so daß der Stauschacht gleichmäßig befüllt werden kann. Auf zusätzliche Mittel zur Vergleichmäßigung des Produktstromes über die Breite kann daher verzichtet werden.This object is achieved with the subject matter of claim 1 in particular in that the viewing space is divided by partitions into chambers, wherein each partition is broken. Due to the subdivision of the viewing space, a uniform distribution of the product stream or the tobacco portions over the width of the viewing means or the viewing space is substantially simplified, since the air flow within the viewing space can only slightly spread apart the product stream or the tobacco portions, so that the stowage uniform can be filled. Additional means for equalizing the product flow across the width can therefore be dispensed with.

In einer bevorzugten Weiterbildung der Erfindung weist der Sichtraum mehrere, vorzugsweise sieben, voneinander getrennte Kammern auf. Die Bildung mehrere einzelner und unabhängiger Kammern erleichtert die gleichmäßige Verteilung des Produktstroms über die Breite des Sichtraumes, so daß die Befüllung des nachgeordneten Stauschachtes zwangsläufig ebenfalls gleichmäßig erfolgt.In a preferred development of the invention, the viewing space has a plurality of, preferably seven, separate chambers. The formation of several individual and independent chambers facilitates the uniform distribution of the product flow across the width of the viewing space, so that the filling of the downstream Stächachtes inevitably also takes place evenly.

Vorteilhafterweise verfügt jede Kammer im Bereich einer Vorderseite des Sichtmittels über einen eigenen Zugang. Dadurch ist die gleichmäßige Befüllung des Sichtraumes sichergestellt, so daß die Kammern gleichmäßig befüllbar sind.Advantageously, each chamber has its own access in the region of a front side of the viewing means. As a result, the uniform filling of the viewing space is ensured, so that the chambers are filled evenly.

Erfindungsgemäss sind die Kammern durch Trennwände gebildet, die sich von gegenüberliegenden Seiten des Sichtmittels, nämlich von der Vorderwand bis zur Rückwand erstrecken und besonders vorteilhaft mindestens teilweise durchbrochen sind. Diese Art der Ausbildung gewährleistet auf besonders zuverlässige und gleichzeitig materialsparende Weise die Trennung des Produktstroms in mehrere Teilströme innerhalb des Sichtraumes. Auch ermöglicht die offene Ausbildung der Trennwände einen Eingriff in den Sichtraum von außen mit geringem Aufwand, und zwar in sämtliche Kammern.According to the invention, the chambers are formed by partitions which extend from opposite sides of the viewing means, namely from the front wall to the rear wall and are particularly advantageously at least partially perforated. This type of training ensures in a particularly reliable and at the same time material-saving way, the separation of the product flow into several streams within the viewing space. Also, the open design of the partitions allows an intervention in the viewing space from the outside with little effort, in all chambers.

Vorzugsweise ist der Sichtraum von außen einsehbar ausgebildet, wodurch die ständige Überwachung des Sichtungsprozesses on-line gewährleistet ist.Preferably, the viewing space is formed visible from the outside, whereby the constant monitoring of the viewing process is ensured on-line.

Sichtmittel dienen innerhalb von Verteilervorrichtungen zum Sichten eines Produktstroms , insbesondere zum Trennen von zu verarbeitenden und von nicht zu verarbeitenden Anteilen des Produktstroms.Sighting agents are used within dispensing devices for sifting through a product stream, particularly for separating portions of the product stream to be processed and unprocessed.

In der Figur 1 ist eine Verteilervorrichtung 10 mit ihren für das Verständnis der Erfindung hilfreichen, wesentlichen Komponenten dargestellt. Dazu gehören in Transportrichtung des Produktstroms ausgehend von einem Reservoir 11 ein Förderer, der vorzugsweise als Steilförderer 12 ausgebildet ist, ein Sichtmittel 13, eine sich an das Sichtmittel 13 anschließende Transportstrecke 14 sowie ein Stauschacht 15. Das Sichtmittel 13 weist vorzugsweise einen Zugang 16 zum Eingeben der vom Steilförderer 12 zugeführten Tabakportionen, die den zu sichtenden Produktstrom bilden, auf. Im Bereich des Zugangs 16 ist optional eine Vereinzelungswalze 17 angeordnet, die den Übergang der Tabakportionen vom Steilförderer 12 in das Sichtmittel 13 unterstützt.In the FIG. 1 a distributor device 10 is shown with its essential components useful for understanding the invention. These include in the transport direction of the product stream, starting from a reservoir 11, a conveyor, which is preferably designed as a steep conveyor 12, a sight 13, a to the The viewing means 13 preferably has an access 16 for inputting the tobacco portions supplied by the vertical conveyor 12, which form the product stream to be viewed. In the area of the access 16, a separating roller 17 is optionally arranged, which supports the transition of the tobacco portions from the vertical conveyor 12 into the viewing means 13.

Das Sichtmittel 13 umfaßt einen Sichtraum 18. Der Sichtraum 18 ist aus einer Vorderwand 19, einer Rückwand 20 sowie Seitenwänden 21, 22 gebildet. Innerhalb des Sichtraums 18 ist eine Sichtstrecke 23 definiert, entlang der der Produktstrom mittels einer Luftströmung gesichtet wird. Die Vorderwand 19 und die Rückwand 20 sind beabstandet und zweckmäßigerweise im wesentlichen parallel zueinander angeordnet und zick-zack-förmig zur Bildung eines sogenannten Zick-Zack-Sichters ausgebildet. Der Zick-Zack-Sichter ist im wesentlichen vertikal ausgerichtet. Der Zugang 16 in den Sichtraum 18 ist vorzugsweise in der oberen Hälfte des Sichtraumes 18 an der Vorderwand 19 angeordnet.The viewing means 13 comprises a viewing space 18. The viewing space 18 is formed of a front wall 19, a rear wall 20 and side walls 21, 22. Within the viewing space 18, a sighting line 23 is defined, along which the product stream is sighted by means of an air flow. The front wall 19 and the rear wall 20 are spaced apart and expediently arranged substantially parallel to each other and zigzag-shaped to form a so-called zig-zag separator. The zig-zag sifter is oriented substantially vertically. The access 16 in the viewing space 18 is preferably arranged in the upper half of the viewing space 18 on the front wall 19.

Der Sichtraum 18 ist in mindestens zwei, vorzugsweise mehrere Abschnitte 24 unterteilt. Jeder Abschnitt 24 erstreckt sich im wesentlichen vertikal in Richtung der Sichtstrecke 23. In einer in Figur 2 dargestellten nicht erfindungsgemäßen Ausführungsform sind die Abschnitte 24 vollständig gegeneinander abgeschirmt, indem der Sichtraum 18 in vorzugsweise sieben separate Kammern 25 unterteilt ist, die innerhalb des Sichtmittels 13 keinen Zugang zueinander haben. Innerhalb jeder Kammer 25 verläuft die Sichtstrecke 23, bzw. ein Teil derselben derart, daß sich sieben einzelne Sichtstrecken 23 parallel aber getrennt voneinander im Sichtraum 18 erstrecken. Die Kammern 25 sind durch Trennwände 26 gebildet, die sich von der Vorderwand 19 zur Rückwand 20 erstrecken. Vorzugsweise ist jeder Kammer 25 ein Zugang 16 zugeordnet. Die Trennwände 26 sind ebenso wie die Seitenwände 21, 22 mindestens teilweise transparent ausgebildet, so daß eine Inspektion des gesamten Sichtraumes 18 von außen gewährleistet ist.The viewing space 18 is divided into at least two, preferably a plurality of sections 24. Each section 24 extends substantially vertically in the direction of the sight line 23. In an in FIG. 2 illustrated non-inventive embodiment, the sections 24 are completely shielded from each other by the viewing space 18 is divided into preferably seven separate chambers 25 which have no access to each other within the viewing means 13. Within each chamber 25, the line of sight 23, or a part thereof extends such that seven individual lines of sight 23 extend parallel but separated from each other in the viewing space 18. The chambers 25 are formed by partitions 26 which extend from the front wall 19 to the rear wall 20. Preferably, each chamber 25 is associated with an access 16. The partitions 26 are as well as the side walls 21, 22 formed at least partially transparent, so that an inspection of the entire viewing space 18 is ensured from the outside.

Die Trennwände 26 erstrecken sich eingangsseitig, also im Bereich des oder jedes Zugangs 16, an der die Übergabe der Tabakportionen an das Sichtmittel 13 erfolgt, bis an den Steilförderer 12 bzw. die Vereinzelungswalze 17. Die aus dem Steilförderer 12 zugeführten Tabakportionen sind damit zwangsläufig in eine der Kammern 25 führbar. Ausgangsseitig, also im Bereich des Übergangs zwischen dem Sichtmittel 13 und der Transportstrecke 14 erstrecken sich die Trennwände 26 bis in die Transportstrecke 14 hinein. In einer nicht dargestellten Ausführungsform können sich die Trennwände 26 auch innerhalb der Transportstrecke 14 erstrecken, derart, daß der gesichtete Produktstrom, insbesondere also die zur Verarbeitung geeigneten Anteile des Produktstroms, aus mehreren Kanälen innerhalb der Transportstrecke 14 gleichmäßig über die Breite verteilt bis in den Stauschacht 15 geleitet werden können.The dividing walls 26 extend on the input side, ie in the region of the or each access 16 at which the transfer of the tobacco portions to the viewing means 13 takes place, as far as the steep conveyor 12 or the separating roller 17. The out of the vertical conveyor 12 supplied tobacco portions are thus inevitably in one of the chambers 25 feasible. On the output side, ie in the region of the transition between the viewing means 13 and the transport path 14, the partitions 26 extend into the transport path 14. In one embodiment, not shown, the dividing walls 26 may extend within the transport path 14, such that the sighted product stream, ie in particular the portions of the product stream suitable for processing, evenly distributed across the width of several channels within the transport path 14 into the stowage 15 can be directed.

Die erfindungsgemäße Ausführungsform ist im wesentlichen identisch aufgebaut, so daß auf eine detaillierte Beschreibung verzichtet wird. Für gleiche Teile werden dieselben Bezugszeichen verwendet. Wie beansprucht sind die Trennwände 26 bei der in den Figuren 3 bis 6 gezeigten Ausführungsform durchbrochen. Das bedeutet, daß die Kammern 25 mindestens teilweise offen ausgebildet sind, so daß benachbarte Kammern 25 jeweils untereinander in Verbindung stehen. Hierzu erstrecken sich jeweils eine Trennwand 26 bildende Leitelemente 27 bzw. 28 von der Vorderwand 19 bzw. Rückwand 20 aufeinander zu, wobei die Leitbleche 27 bzw. 28 jeder Trennwand 26 innerhalb einer Ebene liegen und beabstandet zueinander angeordnet sind, so daß zwischen den Stirnseiten der entgegengesetzten Leitelemente 27, 28 einer offenen Trennwand 26 ein Abstand von vorzugsweise ca. 30mm besteht.The embodiment of the invention is constructed essentially identical, so that is dispensed with a detailed description. The same reference numerals are used for the same parts. As claimed, the partitions 26 are in the in the FIGS. 3 to 6 broken embodiment shown. This means that the chambers 25 are at least partially open, so that adjacent chambers 25 are each in communication with each other. For this purpose, each extending a partition wall 26 guide elements 27 and 28 of the front wall 19 and rear wall 20 toward each other, wherein the baffles 27 and 28 of each partition 26 lie within a plane and are spaced from each other, so that between the end faces of opposite guide elements 27, 28 of an open partition wall 26 is a distance of preferably about 30mm.

In der Ausführungsform gemäß Figur 4 erstrecken sich die Leitbleche 27, 28 zur Bildung der Kammern 25 in im wesentlichen vertikaler Richtung von einem unteren Bodenbereich 29 durchgängig bis zu einem oberen Austrittsbereich 30 des Produktstroms aus dem Sichtraum 18. Mit anderen Worten sind die Leitbleche 27, 28 auch mit einem Radius um sämtliche Eckbereiche 31 der zick-zack-förmigen Vorderwand 19 bzw. Rückwand 20 herumgezogen. Im Bereich des Zugangs 16 bzw. der Zugänge 16 laufen die Leitbleche 27, 28 rampenartig aus, derart, daß der Bereich jedes Zugangs 16 bzw. der Übergang in den Sichtraum 18 absatzlos ist.In the embodiment according to FIG. 4 The baffles 27, 28 extend to form the chambers 25 in a substantially vertical direction from a lower bottom portion 29 continuously up to an upper outlet portion 30 of the product stream from the viewing space 18. In other words, the baffles 27, 28 with a radius to all corner portions 31 of the zig-zag-shaped front wall 19 and rear wall 20 pulled around. In the area of the access 16 or the entrances 16, the baffles 27, 28 run out in a ramp-like manner, such that the area of each access 16 or the transition into the viewing area 18 is free of outlet.

Die Leitbleche 27, 28 in der Ausführungsform gemäß Figur 5 sind mindestens in einigen der Eckbereiche 31 mindestens teilweise unterbrochen. Das bedeutet, daß die Leitbleche 27, 28 vor bzw. hinter den entsprechenden Eckbereichen 31 enden, derart, daß die betroffenen Eckbereiche 31 frei von Leitblechen 27, 28 sind. Die Auswahl der Eckbereiche 31, die frei von Leitblechen 27, 28 sind, ist variabel und hängt ebenso wie die Dimension und Gestaltung der Leitbleche 27, 28 entscheidend von den Umlenkeigenschaften des zu sichtenden Produktstroms ab. Auch haben die Strömungsgeschwindigkeiten der Luft innerhalb der Sichtstrecke 23 sowie die Winkel der zick-zack-förmigen Vorderwand 19 bzw. Rückwand 20 Einfluß auf die Leitbleche 27, 28. Die Breite jeder Kammer 25 beträgt üblicherweise zwischen 140 und 160mm, vorzugsweise jedoch 147mm. Die Anzahl der Kammern 25 ist variabel. Jede Kammer 25 ist von außen frei zugänglich. Hierzu sind die Seitenwände 21, 22 lösbar befestigt, und zwar an (nicht dargestellten) Flanschblechen, die sich winklig von der Vorderwand 19 bzw. Rückwand 20 erstrecken.The baffles 27, 28 in the embodiment according to FIG. 5 are interrupted at least in some of the corner regions 31 at least partially. This means that the baffles 27, 28 terminate in front of or behind the corresponding corner regions 31, in this way the affected corner regions 31 are free of baffles 27, 28. The selection of the corner regions 31, which are free of baffles 27, 28, is variable and, like the dimension and design of the baffles 27, 28, depends crucially on the deflecting properties of the product stream to be observed. Also, the flow velocities of the air within the line of sight 23 and the angles of the zig-zag-shaped front wall 19 and rear wall 20 influence the baffles 27, 28. The width of each chamber 25 is usually between 140 and 160mm, but preferably 147mm. The number of chambers 25 is variable. Each chamber 25 is freely accessible from the outside. For this purpose, the side walls 21, 22 releasably secured, namely on (not shown) Flanschblechen which extend at an angle from the front wall 19 and rear wall 20.

Aus der Figur 7 ist eine weitere Einzelheit der Verteilervorrichtung 10 ersichtlich. Der in Figur 7 dargestellte Steilförderer 12 besteht im wesentlichen aus dem eigentlichen Förderband 35 sowie einem Rahmenelement 36, das das Förderband 35 stützt. Das Förderband 35 weist über die gesamte Breite Mitnahmemittel 37 auf, die in der gezeigten Ausführungsform als sogenannte Kämme 38 ausgebildet sind. Mehrere, vorzugsweise sieben, Kämme 38 sind über die gesamte Breite des Förderbandes 35 nebeneinander verteilt, so daß Tabak oder dergleichen gleichmäßig über die gesamte Breite des Förderbandes 35 sicher dem Sichtmittel 13 zugeführt werden kann. Die Anzahl der Kämme 38 entspricht zweckmäßigerweise der Anzahl der zu befüllenden Abschnitte 24 bzw. Kammern 25. In Transportrichtung des Förderbandes 35 sind die Kämme 38 versetzt zueinander angeordnet. Durch diese Anordnung wird eine Überlappung von Tabak oder dergleichen im Bereich der Kämme 38 vermieden, was wiederum das Einfädeln bzw. Einführen des Tabaks in die Kammern 25 vereinfacht.From the FIG. 7 a further detail of the distributor device 10 can be seen. The in FIG. 7 shown steep conveyor 12 consists essentially of the actual conveyor belt 35 and a frame member 36 which supports the conveyor belt 35. The conveyor belt 35 has over the entire width driving means 37, which are formed in the embodiment shown as so-called combs 38. Several, preferably seven, combs 38 are distributed over the entire width of the conveyor belt 35 adjacent to each other, so that tobacco or the like can be fed uniformly over the entire width of the conveyor belt 35 to the sight 13. The number of combs 38 expediently corresponds to the number of sections 24 or chambers 25 to be filled. In the transport direction of the conveyor belt 35, the combs 38 are offset from one another. By this arrangement, an overlap of tobacco or the like in the region of the combs 38 is avoided, which in turn simplifies the threading or insertion of the tobacco into the chambers 25.
