Description

Die Erfindung betrifft eine Vorrichtung zur Fremdkörperabscheidung aus einem Tabakstrom, wobei eine erste Fördervorrichtung für den Tabakstrom vorgesehen ist, wobei in Förderrichtung stromabwärts der ersten Fördervorrichtung eine Fremdkörpererkennungsvorrichtung vorgesehen ist, an die sich weiter stromabwärts eine Fremdkörperaustoßvorrichtung anschließt, wobei stromabwärts der Fremdkörperaustoßvorrichtung eine zweite Fördervorrichtung für einen von Fremdkörpern im Wesentlichen befreiten Tabakstrom vorgesehen ist.The invention relates to a device for foreign body separation from a tobacco stream, wherein a first conveying device is provided for the tobacco stream, wherein in the conveying direction downstream of the first conveying device, a foreign body detection device is provided, to which further downstream a Fremdkörperaustoßvorrichtung connects, downstream of the Fremdkörperaustoßvorrichtung a second conveyor for a substantially freed from foreign bodies tobacco stream is provided.

Entsprechende Vorrichtungen zur Fremdkörperabscheidung sind hinlänglich bekannt. Es wird hierzu beispielsweise auf EP 1 520 488 A1 verwiesen, bei der eine Trenneinrichtung zur Aufteilung des Tabakmassestroms in einer Vorrichtung zum Ausscheiden vom Fremdkörpern aus einem Tabakmassestrom vorgesehen ist, die einen die Fremdkörper im Wesentlichen enthaltenden ersten Teiltabakmassestrom und einen von den Fremdkörpern im Wesentlichen befreiten zweiten Teiltabakmassestrom aufweist. Diese Vorrichtung weist einen Fremdkörperabscheider auf, der beispielsweise Laserdetektoren zum Abtasten des Tabakmassestroms sowie Ausblasdüsen zum Selektieren und Aussondern von Fremdkörpern aus dem Tabakmassestrom aufweist.Corresponding devices for foreign body separation are well known. It is for this purpose, for example EP 1 520 488 A1 Reference is made, in which a separating device for dividing the tobacco mass flow is provided in a device for excretion of foreign bodies from a tobacco mass flow, the foreign body substantially containing a first Teiltabakmassestrom and having a second Teiltabakmassestrom substantially freed from the foreign bodies. This device comprises a foreign body separator having, for example, laser detectors for sensing the tobacco mass flow and exhaust nozzles for selecting and rejecting foreign bodies from the mass tobacco stream.

In EP 0 902 732 B1 ist ein Fördersystem beschrieben, das eine optische Prüfstation und eine Sortierstation aufweist. Bei der Verarbeitung eines Tabakstroms, insbesondere zur möglichst vollständigen Beseitigung von Fremdkörpern bzw. weitgehenden Beseitigung von Fremdkörpern, so dass ein von Fremdkörpern befreiter Tabakstrom entsteht, kommt es durch den Tabakstaub zu Verschmutzungen. Insbesondere verschmutzen optische Komponenten relativ schnell, weswegen diese regelmäßig zu reinigen sind. Derartige Komponenten sind allerdings üblicherweise nur schwer zugänglich, so dass die Reinigung für das Reinigungspersonal mühsam und zeitaufwändig ist.In EP 0 902 732 B1 a conveyor system is described which comprises an optical inspection station and a sorting station. In the processing of a stream of tobacco, in particular for the most complete removal of foreign bodies or extensive removal of foreign bodies, so that a liberated from foreign bodies tobacco stream, it comes through the tobacco dust to contamination. In particular, optical components foul relatively quickly, which is why they are cleaned regularly. However, such components are usually difficult to access, so that the cleaning for the cleaning personnel is tedious and time consuming.

Es ist die Aufgabe der vorliegenden Erfindung, die Reinigung und die Wartung, Reparatur, Kontrolle und Einstellung von Komponenten in einer Vorrichtung zur Fremdkörperabscheidung aus einem Tabakstrom vereinfacht und mit wenig Zeitaufwand zu ermöglichen.It is the object of the present invention to facilitate the cleaning and the maintenance, repair, control and adjustment of components in a device for foreign body separation from a tobacco stream and with little expenditure of time.

Gelöst wird diese Aufgabe durch eine Vorrichtung zur Fremdkörperabscheidung aus einem Tabakstrom, wobei eine erste Fördervorrichtung für den Tabakstrom vorgesehen ist, wobei in Förderrichtung stromabwärts der ersten Fördervorrichtung eine Fremdkörpererkennungsvorrichtung vorgesehen ist, an die sich weiter stromabwärts eine Fremdkörperausstoßvorrichtung anschließt, wobei stromabwärts der Fremdkörperausstoßvorrichtung eine zweite Fördervorrichtung für einen von Fremdkörpern im Wesentlichen befreiten Tabakstrom vorgesehen ist, die dadurch weitergebildet ist, dass eine Trennstelle in der Vorrichtung zur Fremdkörperabscheidung zwischen der ersten Fördervorrichtung und der zweiten Fördervorrichtung vorgesehen ist, wobei die Trennstelle die Vorrichtung zur Fremdkörperabscheidung in einen stromaufwärtigen Abschnitt und einen stromabwärtigen Abschnitt trennt, wobei der stromaufwärtige Abschnitt mit dem stromabwärtigen Abschnitt lösbar verbindbar oder verbunden ist und die beiden Abschnitte relativ zueinander bewegbar sind.This object is achieved by a device for foreign body separation from a tobacco stream, wherein a first conveying device is provided for the tobacco stream, wherein in the conveying direction downstream of the first conveying device, a foreign body detection device is provided, which is further downstream of a foreign body ejection device, downstream of the foreign body ejection device, a second Conveying device for a substantially freed from foreign bodies Tobacco flow is provided, which is further characterized in that a separation point is provided in the device for foreign body separation between the first conveyor and the second conveyor, wherein the separation point separates the device for foreign body separation in an upstream portion and a downstream portion, wherein the upstream portion with the downstream portion is detachably connectable or connected and the two sections are movable relative to each other.

Durch die erfindungsgemäße Vorrichtung zur Fremdkörperabscheidung ist es für Bedienpersonen sehr einfach möglich, an die zu reinigenden Komponenten, insbesondere optische Komponenten wie Sichtfenster, Spiegel, Kameraobjektive etc., zu gelangen, und zwar ohne dass umfangreiche Umbaumaßnahmen notwendig sind und auch so, dass für die Bedienperson ein bequemer Zugang bzw. eine bequeme Reinigung ermöglich ist.The device according to the invention for foreign body separation, it is very easy for operators to get to the components to be cleaned, especially optical components such as viewing windows, mirrors, camera lenses, etc., and without extensive reconstruction measures are necessary and also so that for Operator is a convenient access or a convenient cleaning is possible.

Im Rahmen der Erfindung bedeutet ein von Fremdkörpern befreiter Tabakstrom, dass der Tabakstrom im Wesentlichen von Fremdkörpern befreit ist.In the context of the invention, a tobacco stream freed from foreign bodies means that the tobacco stream is substantially freed from foreign bodies.

Besonders einfach und schnell ist eine Reinigung dann möglich, wenn zum Bewegen des stromabwärtigen Abschnitts relativ zum stromaufwärtigen Abschnitt der stromabwärtige Abschnitt auf einem Lager, insbesondere Rollenlager, gelagert ist. Zum lösbaren Verbinden können beispielsweise Schnappverschlüsse zwischen den beiden Abschnitten vorgesehen sein. Es können auch Rastmittel vorgesehen sein, die vor dem Lösen der Verbindung beispielsweise eingedrückt werden, um den eingerasteten Zustand zu lösen.Particularly simple and fast cleaning is possible if, for moving the downstream portion relative to the upstream portion of the downstream portion on a bearing, in particular roller bearings, is stored. For releasable connection, for example snap closures can be provided between the two sections. It can also be provided locking means which are pressed, for example, before releasing the connection to release the locked state.

Wenn vorzugsweise die Trennstelle zwischen der Fremdkörperausstoßvorrichtung und der zweiten Fördervorrichtung oder zwischen der ersten Fördervorrichtung und der Fremdkörpererkennungsvorrichtung liegt, kann eine Bedienperson unmittelbar auf die zu reinigenden Teile der Fremdkörperabscheidungsvorrichtung zugreifen.Preferably, when the separation point between the foreign body ejection device and the second conveying device or between the first conveying device and the foreign matter recognizing device, an operator can directly access the parts to be cleaned of the foreign matter depositing device.

Vorzugsweise ist der stromabwärtige Abschnitt linear bewegbar. Unter einer linearen Bewegbarkeit wird insbesondere eine translatorische Bewegbarkeit bzw. eine lineare oder translatorische Bewegung verstanden. Hierdurch kann der stromabwärtige Abschnitt mit relativ wenig Kraftaufwand bewegt werden. Besonders sicher ist das Bewegen des stromabwärtigen Abschnitts relativ zum stromaufwärtigen Abschnitt dann, wenn das Lager waagerecht ausgerichtet ist. Hierbei ist insbesondere zu berücksichtigen, dass der stromabwärtige Abschnitt im Bereich von 500 kg bis 1 t wiegen kann, so dass es, um Verletzungen und Beschädigungen zu vermeiden, sinnvoll ist, das Lager waagerecht auszurichten.Preferably, the downstream portion is linearly movable. Linear mobility is understood in particular to mean translational mobility or a linear or translatory movement. As a result, the downstream portion can be moved with relatively little effort. Particularly safe is moving the downstream portion relative to the upstream portion when the bearing is level. It should be noted in particular that the downstream section can weigh in the range of 500 kg to 1 t, so that, in order to avoid injury and damage, it makes sense to align the bearing horizontally.

Vorzugsweise weist der stromabwärtige Abschnitt ein Gehäuse auf, in das eine Luftabzugshaube integriert ist. Die Luftabzugshaube dient dazu, Förderluft zum Fördern des Tabakstroms abzuführen, wobei dann entsprechend die Förderluft von dem Tabakstrom und insbesondere von dem von Fremdkörpern befreiten Tabakstrom entsprechend getrennt wird. Die abgeführte Förderluft kann entsprechend auch in den Förderluftstrom zurückgeführt werden bzw. ein Teil hiervon. Damit kann die Luftabzugshaube auch als Teil eines Umluftsystems angesehen werden.Preferably, the downstream portion has a housing, in which an air extraction hood is integrated. The air exhaust hood serves to discharge conveying air for conveying the tobacco stream, in which case the conveying air is correspondingly separated from the tobacco stream and in particular from the tobacco stream freed of foreign bodies. The discharged conveying air can be correspondingly also returned to the conveying air flow or a part thereof. Thus, the air extraction hood can also be regarded as part of a recirculation system.

Vorzugsweise ist die Luftabzugshaube mit einer Luftförderleitung verbindbar oder verbunden, die zu einem Eingang eines Ventilators führt, wobei der Ausgang des Ventilators mit einem Eingang der ersten Fördervorrichtung verbunden ist. Hierdurch wird effizient die über die Luftabzugshaube abgeförderte Förderluft wenigstens zum Teil zurückgeführt, um wieder als Förderluft zu dienen. Die Luftförderleitung ist vorzugsweise zumindest in dem Verbindungsbereich mit der Luftabzugshaube oder einer mit der Luftabzugshaube verbundenen Förderleitung linear verbindbar. Die Verbindung zwischen der Luftabzugshaube und der Luftförderleitung kann simultan mit der Bewegbarkeit bzw. der Bewegung des stromabwärtigen Abschnitts und des stromaufwärtigen Abschnitts voneinander wegbewegt bzw. aufeinander zubewegt werden. Insbesondere bei einer waagerechten Bewegung und einer waagerechten Lage der Luftförderleitung ist eine sichere Verbindbarkeit und Trennbarkeit der Luftförderleitung mit der Luftabzugshaube möglich. Die Luftabzugshaube weist hierzu beispielsweise eine, insbesondere mit einer umlaufenden Abdichtung versehene, Öffnung auf, in die die Luftförderleitung einbringbar ist bzw. eingebracht ist.Preferably, the air extraction hood can be connected or connected to an air delivery line which leads to an inlet of a fan, wherein the outlet of the fan is connected to an inlet of the first delivery device. As a result, the conveying air conveyed away via the air extraction hood is efficient at least for Part returned to serve again as a conveying air. The air delivery line is preferably linearly connectable at least in the connection region with the air extraction hood or a conveyor line connected to the air extraction hood. The connection between the air extraction hood and the air delivery duct may be moved away from each other simultaneously with the mobility of the downstream portion and the upstream portion. In particular, in a horizontal movement and a horizontal position of the air conveyor line a secure connectivity and separability of the air conveyor line with the air extraction hood is possible. For this purpose, the air extraction hood has, for example, an opening, in particular provided with a circumferential seal, into which the air delivery line can be introduced or introduced.

Vorzugsweise umfasst die erste Fördervorrichtung einen Kanal, in dem ein Förderluftstrom fließt. Ferner vorzugsweise weist die erste Fördervorrichtung ein Förderband auf. Besonders bevorzugt ist, wenn ein Kanal und ein Förderband vorgesehen sind. Das Förderband bewegt sich ferner vorzugsweise mit der gleichen Geschwindigkeit wie die Förderluft. Die Geschwindigkeit ist hierbei vorzugsweise in einem Bereich von 2 bis 8 m/s, insbesondere bei 5 bis 6 m/s.Preferably, the first conveyor device comprises a channel in which a conveying air flow flows. Furthermore, preferably, the first conveying device has a conveyor belt. It is particularly preferred if a channel and a conveyor belt are provided. The conveyor belt also preferably moves at the same speed as the conveying air. The speed here is preferably in a range of 2 to 8 m / s, in particular 5 to 6 m / s.

Vorzugsweise liegt das Ausmaß der Bewegung des stromabwärtigen Abschnitts zwischen 30 cm und 1 m, insbesondere zwischen 40 cm und 80 cm, vorzugsweise bei 60 cm. In diesem Fall kann eine Bedienperson ohne große Schwierigkeiten zwischen die beiden Abschnitte treten bzw. sich dorthin begeben, um die zu reinigenden Teile der Fremdkörperabscheidungsvorrichtung reinigen zu können. Diese Teile sind vorzugsweise in etwa in Augenhöhe der Bedienperson angeordnet, also in einer Höhe von 1,50 m bis 1,80 m vom Boden, so dass ohne viel Mühe eine Reinigung erfolgen kann.Preferably, the amount of movement of the downstream section is between 30 cm and 1 m, in particular between 40 cm and 80 cm, preferably at 60 cm. In this case, an operator can easily step between the two sections to clean the parts to be cleaned of the foreign-body separation device. These parts are preferably arranged approximately at eye level of the operator, ie at a height of 1.50 m to 1.80 m from Soil, so that cleaning can be done without much effort.

Vorzugsweise ist das Lager auf Standfüßen montiert, wobei eine vertikale Achse durch den Schwerpunkt des stromabwärtigen Abschnitts in jeder Bewegungsposition zwischen den Standfüßen liegt oder durch die Standfüße geht. Hierdurch ist eine sichere Lagerung des stromabwärtigen Abschnitts auf den Standfüßen ermöglicht und außerdem wird hierdurch ermöglicht, dass die Standfüße ausreichend weit von dem stromaufwärtigen Abschnitt entfernt angeordnet sind, so dass eine Bedienperson bequem zwischen die beiden Abschnitte treten kann und auch nicht von den Standfüßen behindert wird. Für eine vereinfachte Reinigung des Bodens unter der Maschine haben die Standfüße eine Höhe von wenigstens 20 cm, vorzugsweise 30 cm.Preferably, the bearing is mounted on feet, with a vertical axis through the center of gravity of the downstream portion in any position of movement between the feet or passes through the feet. In this way, a safe storage of the downstream portion is allowed on the feet and also this allows the feet are arranged sufficiently far away from the upstream portion, so that an operator can easily pass between the two sections and is not hindered by the feet , For a simplified cleaning of the floor under the machine, the feet have a height of at least 20 cm, preferably 30 cm.

Vorzugsweise ist bzw. sind die Standfüße, die in Förderrichtung des Tabakstroms stromaufwärts liegen und auf denen der stromabwärtige Abschnitt getragen wird, mit einem Abstand von wenigstens 50 cm, bevorzugt bis zu 1,50 m, von dem ersten Abschnitt entfernt angeordnet. Der Abstand liegt bevorzugt bei 1 m.Preferably, the feet, which are upstream in the conveying direction of the tobacco stream and on which the downstream portion is carried, are spaced from the first portion by a distance of at least 50 cm, preferably up to 1.50 m. The distance is preferably 1 m.

Fig. 1 zeigt schematisch eine erfindungsgemäße Vorrichtung zur Fremdkörperabscheidung, umfassend zwei Abschnitte 19 und 20, die an der Trennlinie 18', die strichpunktiert dargestellt ist, trennbar ist. Die erfindungsgemäße Vorrichtung zur Fremdkörperabscheidung nimmt Tabak bei einem Tabakeinlass 33 auf. In dem Tabakeinlass 33 sind schematisch vier Einzugsrollen angedeutet. Unterhalb der Einzugsrollen ist ein Tabakförderer 34 in Form einer Rutsche, die auch als Schüttelrutsche ausgestaltet sein kann, vorgesehen, die den eingelassenen Tabak in einem Einlassbereich bzw. einem Eingang 26 in einen Tabakförderer 10 abgibt. Der Tabakförderer 10 ist in diesem Ausführungsbeispiel waagerecht ausgebildet und umfasst in diesem Ausführungsbeispiel einen Tabakförderkanal 41 und ein Tabakförderband 40. Diese beiden Elemente sind in Fig. 3 zu erkennen. Fig. 1 schematically shows a device according to the invention for foreign body deposition, comprising two sections 19 and 20, which is on the dividing line 18 ', which is shown in phantom, separable. The foreign body deposition device according to the invention receives tobacco at a tobacco inlet 33. In the tobacco inlet 33 schematically four feed rollers are indicated. Underneath the intake rollers, a tobacco conveyor 34 in the form of a chute, which may also be designed as a shaking chute, is provided, which discharges the inserted tobacco into an inlet region or an inlet 26 into a tobacco conveyor 10. The tobacco conveyor 10 is formed horizontally in this embodiment and comprises in this embodiment, a tobacco conveying channel 41 and a tobacco conveyor belt 40. These two elements are in Fig. 3 to recognize.

Tabak wird mittels des Tabakförderers 10 umfassend den Tabakförderkanal und das Tabakförderband in Förderrichtung 11 weitertransportiert. Dieser Tabakstrom kann auch Fremdkörper enthalten, die zu entfernen sind. Hierzu sind am Ausgang des Tabakförderers 10 eine Fremdkörpererkennungsvorrichtung 12 und eine Fremdkörperausstoßvorrichtung 13 (siehe Fig. 3) vorgesehen, die in dem Gehäuse 35 untergebracht sind. Mittels der Fremdkörpererkennungsvorrichtung 12 werden Fremdkörper erkannt. Mittels dieser Erkennung wird eine Fremdkörperausstoßvorrichtung 13 angesteuert, die beispielsweise einen Druckluftstoß auf Fremdkörper abgibt und so die Bewegungsrichtung der Fremdkörper vom Tabakförderstrom verändert, um so eine Sortierung vornehmen zu können. Einzelheiten zu der Fremdkörpererkennungsvorrichtung und der Fremdkörperausstoßvorrichtung folgen unter Bezugnahme auf Fig. 3.Tobacco is further transported in the conveying direction 11 by means of the tobacco conveyor 10 comprising the tobacco conveying channel and the tobacco conveyor belt. This tobacco stream may also contain foreign bodies that are to be removed. For this purpose, at the exit of the tobacco conveyor 10, a foreign body detection device 12 and a foreign body ejection device 13 (see Fig. 3 ), which are housed in the housing 35. By means of the foreign body recognition device 12, foreign objects are recognized. By means of this recognition, a foreign body ejection device 13 is driven, which emits, for example, a blast of compressed air to foreign bodies and thus changes the direction of movement of the foreign body from the tobacco flow, so as to be able to perform a sorting. Details of the foreign-matter recognition device and the foreign-matter discharge device will be described with reference to FIG Fig. 3 ,

Die ausgestoßenen Fremdkörper gelangen zusammen mit mitausgestoßenem Tabak auf ein Förderband 31 und werden in dem Bereich eines Absaugrohres 30 gefördert, mittels dessen einige Fremdkörper und auch Tabak abgesaugt wird. Die schweren Fremdkörper werden nicht abgesaugt, sondern werden weitergefördert und in ein Abfördergefäß abgegeben. Die entsprechend durch das Absaugrohr 30 abgesaugten Fremdkörper zuzüglich der durch die Fremdkörperausstoßvorrichtung 13 mit ausgestoßenen Tabakpartikel gelangen in einen Abscheider, der in diesem Ausführungsbeispiel als Zyklon 32 ausgebildet ist, in der der Tabak und die Fremdkörper von der Saugluft getrennt werden und wieder an den Eingang des Tabakförderers 10 gelangen. In diesem Fall gelangen diese Materialien auf einen in Fig. 1 nicht dargestellten hinteren Bereich des Förderbandes 40. Die Materialien gelangen auch wieder in den Bereich der Fremdkörpererkennungsvorrichtung 12 und der Fremdkörperausstoßvorrichtung 13, wonach wieder ein entsprechender Fremdkörperausstoß vorgenommen wird, so dass allerdings weiterer Tabak, der ansonsten verlorengegangen wäre, zu einem von Fremdkörpern befreiten Tabakstrom gelangt. Die nun ein zweites Mal ausgestoßenen Materialien gelangen auf ein Förderband oder einen Förderer, der unterhalb des Förderbandes 31 angeordnet ist und einen Auslass aufweist, der auch in dem Abfördergefäß endet. Anstelle eines Förderbandes 31 kann auch an dieser Stelle eine Schüttelrinne vorgesehen sein oder ein anderer Förderer.The ejected foreign matter, together with co-ejected tobacco, reaches a conveyor belt 31 and is conveyed in the region of a suction pipe 30 by which some foreign matter and also tobacco are sucked out. The heavy foreign bodies are not sucked off, but are conveyed on and discharged into a discharge vessel. The correspondingly sucked through the suction pipe 30 foreign body plus the expelled by the Fremdkörperausstoßvorrichtung 13 with tobacco particles get into a separator which is formed in this embodiment as a cyclone 32, in which the tobacco and the foreign body are separated from the suction air and back to the input of the Tobacco conveyor 10 arrive. In this case, these materials get into a Fig. 1 The back of the conveyor belt 40 is not shown. The materials also pass back into the area of the foreign body detection device 12 and the foreign body ejection device 13, after which a corresponding foreign body ejection is again performed, however additional tobacco, which would otherwise be lost, passes to a freed of foreign bodies tobacco stream. The materials now ejected a second time reach a conveyor belt or a conveyor, which is arranged below the conveyor belt 31 and has an outlet which also ends in the discharge vessel. Instead of a conveyor belt 31 may be provided at this point a vibrating chute or another conveyor.

Das von Fremdkörpern befreite bzw. im Wesentlichen befreite Material, wobei im Rahmen der Erfindung ein Tabakmaterialstrom, der im Wesentlichen von Fremdkörpern befreit ist, als ein von Fremdkörpern befreiter Tabakmaterialstrom bezeichnet wird, gelangt dann auf ein Förderband, das in dem Gehäuse 22 angeordnet ist. Das Gehäuse 22 ist auf einem Rollenlager 21 gelagert, das auf Standfüßen 27 und 27' montiert ist. In dem Gehäuse 22 ist eine Luftabzugshaube 23 integriert, die oberhalb von dem Förderband angeordnet ist. Diese dient dazu, die Förderluft von dem Tabak abzutrennen. Die abgetrennte Förderluft gelangt wieder zurück über eine Luftförderleitung 24 zu einem Ventilator 25, der Förderluft zum Eingang 26 des Tabakförderers 10 abgibt. Auf diese Weise wird ein Umluftsystem erzeugt, wobei beispielsweise ca. 50% der Förderluft wieder zurückgewonnen wird. Wie in Fig. 1 dargestellt ist, existiert eine als strichpunktierte Linie dargestellte Trennstelle 18', die in diesem Fall zwischen dem Gehäuse 22 und dem Gehäuse 35 angeordnet ist. Zudem ist die Trennstelle 18' auch zwischen der Luftförderleitung 24 und der Luftabzugshaube 23 vorgesehen.The liberated or substantially freed from material, wherein in the present invention, a tobacco material stream, which is substantially freed from foreign bodies, is referred to as a liberated from foreign material tobacco material flow, then passes to a conveyor belt, which is arranged in the housing 22. The housing 22 is mounted on a roller bearing 21 which is mounted on feet 27 and 27 '. In the housing 22, an air extraction hood 23 is integrated, which is arranged above the conveyor belt. This serves to separate the conveying air from the tobacco. The separated conveying air passes back again via an air conveying line 24 to a fan 25, which delivers conveying air to the inlet 26 of the tobacco conveyor 10. In this way, a recirculation system is generated, for example, about 50% of the conveying air is recovered. As in Fig. 1 is shown, there is a separation point 18 'shown as a dotted line, which is arranged in this case between the housing 22 and the housing 35. In addition, the separation point 18 'is also provided between the air delivery line 24 and the air exhaust hood 23.

Der stromabwärtige Abschnitt 20 kann von dem stromaufwärtigen Abschnitt 19 dadurch getrennt werden, dass der stromabwärtige Abschnitt 20 von dem stromaufwärtigen Abschnitt 19 auf dem Rollenlager 21 wegbewegt werden kann. Hierdurch ergibt sich eine translatorische Bewegung. Nach dem Wegbewegen ergibt sich eine Konstellation, wie diese beispielsweise in Fig. 2 dargestellt ist. Es ist hierbei zu bemerken, dass der Schwerpunkt des zweiten Abschnitts 20, der mit 28 gekennzeichnet ist bzw. dessen vertikale Achse 29 vorzugsweise immer zwischen oder auf bzw. über den beiden Standfüßen 27 und 27' liegt, um eine stabile Lagerung vorzusehen. In die Lücke zwischen die beiden Abschnitte 19 und 20 kann dann eine Bedienperson bequem treten, um etwaige Teile bzw. Komponenten in dem Gehäuse 35 zu reinigen bzw. auch Komponenten, die in dem Gehäuse 22 angeordnet sind.The downstream portion 20 may be separated from the upstream portion 19 by allowing the downstream portion 20 to be moved away from the upstream portion 19 on the roller bearing 21. This results in a translational movement. After moving away, there is a constellation, as this example in Fig. 2 is shown. It should be noted here that the center of gravity of the second section 20, which is designated by 28 or whose vertical axis 29 is preferably always between or on or above the two feet 27 and 27 ', to provide a stable storage. An operator can then easily step into the gap between the two sections 19 and 20 in order to clean any parts or components in the housing 35 or else components which are arranged in the housing 22.

Zur besseren Veranschaulichung ist in Fig. 3 schematische eine Schnittdarstellung eines Teils der erfindungsgemäßen Vorrichtung zur Fremdkörperabscheidung dargestellt.For a better illustration, see Fig. 3 schematically a sectional view of a portion of the device according to the invention for foreign body separation shown.

Ein Tabakstrom 15 umfassend Tabakpartikel und Fremdkörper 16 wird in Förderrichtung 11 in einem Tabakförderer 10 gefördert. Der Tabakförderer 10 umfasst einen Tabakförderkanal 41 und ein Tabakförderband 40. In dem Tabakförderkanal 41 dient ein Förderluftstrom 52 zum Fördern des Tabaks. Ferner dient auch das Förderband 40 zum Fördern des Tabaks. Um eine möglichst gleichmäßige Förderung des Tabakstroms 15 sowie der in dem Tabakstrom enthaltenen Fremdkörper 16 zu ermöglichen, bewegt sich das Tabakförderband 40 mit der gleichen Geschwindigkeit wie der Förderluftstrom 52.A tobacco stream 15 comprising tobacco particles and foreign matter 16 is conveyed in the conveying direction 11 in a tobacco conveyor 10. The tobacco conveyor 10 comprises a tobacco conveying channel 41 and a tobacco conveyor belt 40. In the tobacco conveying channel 41 serves a conveying air flow 52 for conveying the tobacco. Further, the conveyor belt 40 also serves to convey the tobacco. In order to allow the most uniform possible delivery of the tobacco stream 15 and the foreign body 16 contained in the tobacco stream, the tobacco conveyor belt 40 moves at the same speed as the conveying air flow 52.

Ausgangsseitig des Tabakförderers 10 ist eine Fremdkörpererkennungsvorrichtung 12 vorgesehen, die in diesem Ausführungsbeispiel eine Kamera 45, eine Lichtquelle 46 und zwei Fenster 44 und 44' umfasst. Mittels der Kamera 45 können Fremdkörper von Tabakpartikeln unterschieden werden. Sobald ein Fremdkörper erkannt wird, wird ein Steuersignal auf die Fremdkörperausstoßvorrichtung 13 gegeben, so dass die Druckluftdüse 47, die Teil der Fremdkörperausstoßvorrichtung 13 ist, einen Druckluftstoß 48 in den Tabakstrom 15 abgibt, so dass im Wesentlichen die Fremdkörper 16 aus dem Tabakstrom 15 entfernt werden. Hierdurch werden allerdings auch Tabakpartikel mit aus diesem Tabakstrom entfernt.On the output side of the tobacco conveyor 10, a foreign body detection device 12 is provided, which in this embodiment comprises a camera 45, a light source 46 and two windows 44 and 44 '. By means of the camera 45 foreign bodies can be distinguished from tobacco particles. Once a foreign object is detected, a control signal to the foreign object ejection device 13th given so that the compressed air nozzle 47, which is part of the foreign body ejection device 13, a compressed air blast 48 discharges into the tobacco stream 15, so that substantially the foreign body 16 are removed from the tobacco stream 15. As a result, however, tobacco particles are removed with this tobacco stream.

Um einen gleichmäßigen und ungestörten Flug des Tabakstroms 15 zu ermöglichen, ist zudem unterhalb des Tabakförderers 10 ein Luftförderkanal 42 vorgesehen, der düsenartig ausgebildet ist und einen Luftstrom 43 unterhalb des Tabakstroms 15 abgibt, um an der Ausgangsseite des Tabakförderers 10 die gleichmäßige Förderung des Tabakstroms mit den Fremdkörpern zu ermöglichen.In order to allow a smooth and undisturbed flight of the tobacco stream 15, below the tobacco conveyor 10, an air conveying channel 42 is provided, which is nozzle-like and emits an air stream 43 below the tobacco stream 15 to at the output side of the tobacco conveyor 10, the uniform promotion of tobacco flow with to allow the foreign bodies.

Die ausgesonderten Materialien werden über ein Förderband 31 weggefördert. Um den von den Fremdkörpern befreiten Tabakstrom gleichmäßig aufzufangen und auf einem Förderband 14 zu sammeln, sind zum einen Verteilbleche 49 vorgesehen, die beispielsweise gestaffelt angeordnet sein können, und zwar in einer Stafflung quer zur Förderrichtung des Tabakstroms. Zudem ist ein Trennsieb 51 vorgesehen, mittels dessen effizient Luft abgetrennt werden kann, so dass keine oder möglichst wenig Verwirbelungen in den Bereich der Fremdkörperabtrennung zu dem Tabakgutstrom bzw. dem Tabakstrom, der von Fremdkörpern befreit ist, vorzusehen.The separated materials are conveyed away via a conveyor belt 31. In order to evenly absorb the tobacco stream freed of the foreign bodies and to collect it on a conveyor belt 14, distribution plates 49 are provided which, for example, can be staggered, in a cross-section to the conveying direction of the tobacco stream. In addition, a separating sieve 51 is provided, by means of which air can be separated efficiently, so that no or as little turbulence as possible is provided in the region of the foreign body separation from the tobacco product stream or the tobacco stream, which is freed of foreign bodies.

Es sammelt sich nun ein von Fremdkörpern befreiter Tabakstrom 17 auf dem Förderband 14 an und wird entsprechend quer zur vorherigen Förderrichtung des Tabakstroms 15 abgefördert. Zudem findet eine Trennung von der Förderluft statt, nämlich dadurch, dass ein Luftstrom 50 nach oben durch die Luftabzugshaube 23 abgesaugt wird.It now collects a liberated from foreign bodies tobacco stream 17 on the conveyor belt 14 and is conveyed away transversely to the previous conveying direction of the tobacco stream 15. In addition, a separation of the conveying air takes place, namely the fact that an air flow 50 is sucked up through the air extraction hood 23.

Um nun erfindungsgemäß einfach an die Komponenten zu gelangen, die vom Bedienpersonal zu reinigen sind, wie beispielsweise die Fenster 44 und 44' und auch das Trennsieb 51, ist es nun möglich, den ersten Abschnitt, d.h. den stromabwärtigen Abschnitt 19, von dem zweiten Abschnitt, d.h. dem stromabwärtigen Abschnitt 20, einfach dadurch zu trennen, dass der stromabwärtige Abschnitt 20, der auf dem schematisch angedeuteten Rollenlager 21 gelagert ist, in der Fig. 3 nach rechts weggezogen wird. Die Trennstelle kann hierbei die Trennstelle 18 sein, die strichpunktiert dargestellt ist und zwischen dem Förderband 40 und der Fremdkörpererkennungsvorrichtung 12 liegt oder wie im vorigen Beispiel der Fig. 1 und Fig. 2 die Trennstelle 18' sein, die zwischen der Fremdkörperausstoßvorrichtung 13 und dem Tabakförderband 14 liegt. In beiden Fällen ist es für die Bedienperson einfach, an diese Stellen zu gelangen und eine Reinigung bzw. Säuberung vorzunehmen.In order to easily reach the components according to the invention, which are to be cleaned by the operating personnel, such as the windows 44 and 44 'and also the separating screen 51, it is now possible for the first section, ie the downstream section 19, of the second section , that is, the downstream portion 20, to be simply separated by the downstream portion 20, which is supported on the schematically indicated roller bearing 21, in the Fig. 3 is pulled away to the right. The separation point may in this case be the separation point 18, which is shown in phantom and between the conveyor belt 40 and the foreign body detection device 12 or as in the previous example of Fig. 1 and Fig. 2 the separation point 18 ', which is located between the foreign body ejection device 13 and the tobacco conveyor belt 14. In both cases, it is easy for the operator to get to these locations and perform a cleaning or cleaning.

Für ein besseres Verständnis ist anzumerken, dass die Vorrichtungen, die hier gemäß der Erfindung Gegenstand sind, beispielsweise eine Höhe von 4 m aufweisen und mehrere Tonnen wiegen können. Der wegzubewegende Abschnitt 20 kann zwischen 500 kg und 1 t oder mehr wiegen. Aus diesem Grunde ist es zweckmäßig, die Führung mit Stahlrollen auf einer Schiene vorzusehen. Das heißt, das Rollenlager umfasst vorzugsweise Stahlrollen und eine Stahlschiene. Aufgrund der Erfindung ist es nicht mehr notwendig, ein Podest zu errichten, was auch zu erhöhten Kosten führt. Zudem ist es für die Bedienperson sehr einfach, die entsprechenden zu reinigenden Teile zu reinigen.For a better understanding, it should be noted that the devices subject matter of the invention may for example have a height of 4 m and weigh several tons. The wegzubewegende section 20 can weigh between 500 kg and 1 ton or more. For this reason, it is expedient to provide the guide with steel rollers on a rail. That is, the roller bearing preferably comprises steel rollers and a steel rail. Due to the invention, it is no longer necessary to build a pedestal, which also leads to increased costs. In addition, it is very easy for the operator to clean the corresponding parts to be cleaned.

Alle genannten Merkmale, auch die den Zeichnungen allein zu entnehmenden sowie auch einzelne Merkmale, die in Kombination mit anderen Merkmalen offenbart sind, werden allein und in Kombination als erfindungswesentlich angesehen. Erfindungsgemäße Ausführungsformen können durch einzelne Merkmale oder eine Kombination mehrerer Merkmale erfüllt sein.All mentioned features, including the drawings alone to be taken as well as individual features that are disclosed in combination with other features are considered alone and in combination as essential to the invention. Embodiments of the invention can be fulfilled by individual features or a combination of several features.
