Tabak inklusive Rippen, Tabakmischungen oder dergleichen, besteht, Scheiben abzutrennen, die zur weiteren Verarbeitung verwendet werden. Die Dicke der abzutrennenden Scheiben (Slicedicke) kann variieren. Dazu umfasst die Vorrichtung ein Zuführelement für den Tabakballen. Das Zuführelement ist zum Transportieren des Ballens in Transportrichtung T ausgebildet und bestimmt durch den gewählten Vorschub die zu schneidende Slicedicke. Die Scheiben werden durch das Trennmesser vom Ballen abgetrennt. Um einerseits die zu schneidende Scheibe während des Trennvorgangs zu halten und andererseits die geschnittene Scheibe freizugeben, sind sowohl der Schneidtisch als auch die Gegenhalteplatte verfahrbar. Während des Schneidens/Trennens liegt die zu schneidende Scheibe auf dem Schneidtisch auf. Die Gegenhalteplatte liegt an der Stirnseite des Ballens bzw. der abzuschneidenden Scheibe an und drückt die Scheibe gegen den Ballen.Such devices are used in the tobacco processing industry to separate from a preferably rectangular storage container, so for example a tobacco bale, tobacco cake or the like, which consists of material of the tobacco industry, eg tobacco including ribs, tobacco mixtures or the like, to separate slices, which are used for further processing. The thickness of the slices to be separated (slit thickness) may vary. For this purpose, the device comprises a feed element for the tobacco bales. The feed element is designed to transport the bale in the transport direction T and determines the slit thickness to be cut by the selected feed. The slices are separated from the bale by the separating knife. On the one hand to keep the slice to be cut during the separation process and on the other hand to release the cut slice, both the cutting table and the counter-holding plate are movable. During cutting / cutting, the slice to be cut lies on the cutting table. The counter-holding plate abuts against the front side of the bale or the disc to be cut off and presses the disc against the bale.

Insbesondere die Abstimmung der Bewegungen bzw. der Verfahrwege von Schneidtisch und Gegenhalteplatte sowie deren präzise Ansteuerung sind aufwendig und problematisch.From the EP 0 582 139 A1 a device having the features of the preamble of claim 1 is known.

Such known devices have the disadvantage that several drives, namely in particular for the feed, the cutting blade, the cutting table and the counter-holding plate are necessary, which means on the one hand a considerable design effort and on the other a complex control to tune the individual drives to each other pulls. In particular, the coordination of the movements or the travel paths of the cutting table and counter plate and their precise control are complex and problematic.

Der Erfindung liegt demnach die Aufgabe zugrunde, eine konstruktiv vereinfachte Vorrichtung zum Trennen von Scheiben von einem Ballen zu schaffen.The invention is therefore an object of the invention to provide a structurally simplified device for separating slices of a bale.

Diese Aufgabe wird durch eine Vorrichtung mit den eingangs genannten Merkmalen dadurch gelöst, dass die Gegenhalteplatte antriebslos ausgebildet und gewichtsbelastet passiv entlang horizontal gerichteter Linearführungen in und entgegen der Transportrichtung T bewegbar ist. Durch den Wegfall eines Antriebs für die Gegenhalteplatte ist die erfindungsgemäße Vorrichtung gegenüber herkömmlichen Vorrichtungen konstruktiv einfacher aufgebaut. Entsprechend kann auch auf eine eigene Steuerung für die Gegenhalteplatte bzw. die Anbindung an eine Steuerung der Vorrichtung verzichtet werden, was den Aufbau der Vorrichtung zusätzlich vereinfacht. Mit der gewichtsbelasteten, passiven Bewegbarkeit der Gegenhalteplatte wird ein indirektes Verschieben der Gegenhalteplatte beschrieben, indem rein mechanische Komponenten alleine durch ihre Gewichtsbelastung eine Bewegung der Gegenhalteplatte entgegen der Transportrichtung T gewährleisten.This object is achieved by a device having the features mentioned in the fact that the counter-holding plate is designed without drive and weight-loaded passively along horizontally oriented linear guides in and against the transport direction T is movable. By eliminating a drive for the counter-holding plate device according to the invention over conventional devices structurally simpler structure. Accordingly, a separate control for the counter-holding plate or the connection to a control of the device can be dispensed with, which additionally simplifies the construction of the device. With the weight-loaded, passive mobility of the counter-holding plate, an indirect displacement of the counter-holding plate is described by purely mechanical components alone ensure their weight load movement of the counter-holding plate against the transport direction T.

Eine besonders bevorzugte Ausführungsform der Erfindung zeichnet sich dadurch aus, dass der Schneidtisch entlang horizontal gerichteter Linearführungen parallel zur Gegenhalteplatte aktiv aus einer geöffneten Freigabestellung in eine geschlossene Schneidstellung, in der zwischen dem Zuführelement und dem Schneidtisch ein Spalt zum Durchtritt des Trennmessers gebildet ist, und umgekehrt verfahrbar ist, und der Gegenhalteplatte zum Bewegen entgegen der Transportrichtung T ein gewichtsbelasteter Schwenkmechanismus zugeordnet ist, der permanent an der Gegenhalteplatte anliegt und eine Druckkraft F auf die Gegenhalteplatte ausübt, die der Transportrichtung T entgegenwirkt, und die Gegenhalteplatte zum Bewegen in Transportrichtung T mit dem angetriebenen Schneidtisch mittels eines Anschlag- und Mitnehmermittels in Wirkverbindung bringbar ist. Mit dem Schwenkmechanismus ist eine besonders einfache und kompakte Lösung realisiert, um die Gegenhalteplatte allein durch das Eigengewicht des Schwenkmechanismus permanent entgegen der Transportrichtung T mit einer Druckkraft F zu beaufschlagen, um die Gegenhalteplatte in Richtung des zu bearbeitenden Ballens zu bewegen und gegen den Ballen bzw. die vom Ballen zu schneidende Scheibe zu drücken. Dadurch, dass die Gegenhalteplatte durch den Schwenkmechanismus stets in der maximal möglichen Frontposition gehalten ist, existieren keine Wartezeiten/Reaktionszeiten bei der Ansteuerung der Gegenhalteplatte, so dass die Leistungsfähigkeit der Vorrichtung erhöht werden kann. Für die Bewegung der Gegenhalteplatte in Transportrichtung T zum Zurückziehen der Gegenhalteplatte kann der Antrieb des Schneidtisches verwendet werden, indem die Antriebsbewegung des Schneidtisches mittels des Anschlag- und Mitnehmermittels auf die Gegenhalteplatte übertragbar ist. Der konstruktive und steuerungstechnische Aufwand kann somit reduziert werden.A particularly preferred embodiment of the invention is characterized in that the cutting table along horizontally oriented linear guides parallel to the counter-holding plate active from an open release position into a closed cutting position in which a gap between the feed element and the cutting table for the passage of the separating knife is formed, and vice versa is movable, and the counter-holding plate for moving against the transport direction T a weight-bearing pivot mechanism is assigned, which bears permanently against the counter-holding plate and exerts a compressive force F on the counter-holding plate, which counteracts the transport direction T, and the counter-holding plate for moving in the transport direction T with the driven cutting table by means of a stop and catch means is operatively engageable. With the pivot mechanism, a particularly simple and compact solution is realized to permanently apply the counter-plate alone by the weight of the pivot mechanism against the transport direction T with a compressive force F to move the counter-holding plate in the direction of the bale to be processed and against the bale or to push the disc to be cut by the bale. Due to the fact that the counter-holding plate is always held in the maximum possible front position by the pivot mechanism, there are no waiting times / reaction times in the activation of the counter-holding plate, so that the performance of the device can be increased. For the movement of the counter-holding plate in the transport direction T for retracting the counter-holding plate, the drive of the cutting table can be used by the drive movement of the cutting table by means of the stop and entrainment means is transferable to the counter-holding plate. The design and control engineering effort can thus be reduced.

Vorteilhafterweise ist dem Schneidtisch ein kombiniertes Anschlag- und Mitnehmermittel zugeordnet, mittels dem die Gegenhalteplatte und der Schneidtisch in Wirkverbindung bringbar sind, derart, dass der Schneidtisch bzw. das Anschlag- und Mitnehmermittel einerseits die Bewegung der Gegenhalteplatte entgegen der Transportrichtung T begrenzen und andererseits eine Bewegung der Gegenhalteplatte in Transportrichtung T bewirken kann. Durch diese enge Wirkbeziehung zwischen Schneidtisch und Gegenhalteplatte wird die Gegenhalteplatte über den Schneidtisch quasi zwangsgesteuert stets in der optimalen Position/Lage gehalten.Advantageously, the cutting table is associated with a combined stop and entrainment means, by means of which the counter-holding plate and the cutting table can be brought into operative connection, such that the cutting table or the stop and entrainment on the one hand limit the movement of the counter-holding plate against the transport direction T and on the other hand, a movement the counter-holding plate in the transport direction T can effect. Due to this close operative relationship between the cutting table and the counter-holding plate, the counter-holding plate is virtually always forcibly controlled via the cutting table in the optimum position / position.

Eine zweckmäßige Weiterbildung der Erfindung zeichnet sich dadurch aus, dass die lineare Bewegbarkeit der Gegenhalteplatte entgegen der Transportrichtung T in einer Position unmittelbar vor dem Trennmesser und in Transportrichtung T jeweils durch ein unabhängig vom Schneidtisch wirkendes, zusätzliches Anschlagelement begrenzbar ist. Diese mechanischen Komponenten ermöglichen ein einfaches Freigeben und/oder Begrenzen der Bewegbarkeit der Gegenhalteplatte frei von steuerungstechnischen Problemen. Anders ausgedrückt werden Steuer- und Abstimmungsaktivitäten zwischen Schneidtisch und Gegenhalteplatte durch die Anschlagselemente auf besonders einfache Weise ausgeführt.An expedient development of the invention is characterized in that the linear mobility of the counter-holding plate counter to the transport direction T in a position immediately before the cutting knife and in the transport direction T is limited by an independent of the cutting table acting, additional stop element. These mechanical components allow easy release and / or limiting the mobility of the counter-plate free of control problems. In other words, tax and reconciliation activities are between Cutting table and counter plate performed by the stop elements in a particularly simple manner.

Besonders bevorzugt ist der Schwenkmechanismus an einem Portalträger, an dem auch das Trennmesser vertikal auf und ab bewegbar angeordnet ist, schwenkbar um einen Achse I gelagert. Ein solches Schneidportal führt zu einem kompakten und modularen Aufbau der Vorrichtung, was insbesondere den Austausch von Komponenten erleichtert. Weiterhin gewährleistet die stabile Konstruktion eines Schneidportals die Präzision der Trennschnitte.Particularly preferably, the pivoting mechanism is pivotally mounted about an axis I on a portal carrier on which the separating knife is also arranged to be movable vertically up and down. Such a cutting portal leads to a compact and modular construction of the device, which in particular facilitates the replacement of components. Furthermore, the stable construction of a cutting portal ensures the precision of the cuts.

Vorteilhafterweise ist die Achse I quer zur Transportrichtung T ausgerichtet und weist einen Abstand zum Schneidtisch auf, der größer ist als die Höhe des zu schneidenden Ballens. Durch die Schwenkachse I und deren Position/Lage wird erreicht, dass die Haltekräfte der Gegenhalteplatte mit zunehmender Dicke der Scheiben steigen. Anders ausgedrückt erhöht sich mit durch den in Transportrichtung T vorgeschobenen Ballen ausgelöster, zunehmender Auslenkung des Schwenkmechanismus die entgegen der Transportrichtung T weisende horizontale Komponente der Halte- bzw. Druckkraft F. Dadurch werden Scheiben größerer Dicke und entsprechend mit einem höheren Gewicht zwangsläufig mit einer größeren Kraft gehalten, was die Präzision des Trennvorgangs erhöht.Advantageously, the axis I is aligned transversely to the transport direction T and has a distance from the cutting table which is greater than the height of the bale to be cut. By the pivot axis I and its position / location is achieved that the holding forces of the counter-holding plate increase with increasing thickness of the discs. In other words, increasing the deflection of the pivot mechanism triggered by the bale advancing in the transporting direction T increases the horizontal component of the holding force F facing the transporting direction T. Thus, slices of larger thickness and correspondingly of a higher weight are inevitably loaded with a larger force held, which increases the precision of the separation process.

Die Erfindung ist in einer weiteren Ausgestaltung dadurch gekennzeichnet, dass der Schwenkmechanismus einen Schwenkhebel und einen fest mit diesem verbundenen Stützhebel, der etwa in einem rechten Winkel α zum Schwenkhebel ausgerichtet ist, umfasst. Durch diese Ausbildung des Schwenkmechanismus wird erreicht, dass der Schwenkmechanismus stets mit einer ausreichend hohen Kraft gegen die Gegenhalteplatte drückt.The invention is characterized in a further embodiment, characterized in that the pivoting mechanism comprises a pivot lever and a support arm fixedly connected thereto, which is aligned at approximately a right angle α to the pivot lever. This design of the pivot mechanism ensures that the pivot mechanism always presses against the counter-holding plate with a sufficiently high force.

Voreilhafterweise ist der Schwenkhebel drehbar an einer Querstrebe des Portalträgers gelagert und der Stützhebel liegt mit seinem freien Ende lose an der Gegenhalteplatte an. Dadurch wird zum einen eine kompakte Bauweise ermöglicht. Zum anderen wird die einfache Anpassung an unterschiedliche Schwenkpositionen realisiert.Voreilhafterweise the pivot lever is rotatably mounted on a transverse strut of the gantry and the support lever is located with its free end loosely against the counter-holding plate. This allows for a compact design. On the other hand, the simple adaptation to different pivot positions is realized.

Eine bevorzugte Weiterbildung der Erfindung zeichnet sich dadurch aus, dass am freien Ende des Stützhebels zum Ausgleich der Schwenkbewegung des Schwenkhebels Rollen zum vertikalen Abrollen des Schwenkmechanismus entlang der Gegenhalteplatte angeordnet sind. Dies ermöglicht auf besonders einfache Weise das Ausgleichen vertikaler Bewegungen.A preferred embodiment of the invention is characterized in that at the free end of the support lever to compensate for the pivotal movement of the pivot lever rollers for the vertical rolling of the pivot mechanism along the Countertop are arranged. This makes it possible in a particularly simple way to compensate for vertical movements.

Eine weitere zweckmäßige Ausführungsform ist dadurch gekennzeichnet, dass der Schwenkmechanismus zusätzlich zum Schwenkhebel und Stützhebel mindestens ein Zusatzgewicht umfasst, das vorzugsweise lösbar am Schwenkmechanismus befestigt ist. Durch das Zusatzgewicht kann eine weitere bzw. höhere horizontal wirkende Druckkraft auf die Gegenhalteplatte aufgebracht werden, was die Trennqualität und-präzision verbessert. Die Lösbarkeit und damit Austauschbarkeit ermöglicht das Einstellen bzw. Anpassen der Druckkraft.A further expedient embodiment is characterized in that, in addition to the pivoting lever and the supporting lever, the pivoting mechanism comprises at least one additional weight, which is preferably fastened releasably to the pivoting mechanism. By the additional weight, a further or higher horizontally acting pressure force can be applied to the counter-holding plate, which improves the separation quality and precision. The solubility and thus interchangeability allows adjusting or adjusting the pressure force.

Vorzugsweise ist der Schwenkmechanismus am Portalträger relativ zu diesem vertikal verstellbar angeordnet. Dadurch ist der Winkel β veränderbar. Da die Größe des Winkels β unmittelbar Einfluss auf die Größe der Druckkraft hat, kann damit eine individuelle Einstellung/Anpassung erfolgen.Preferably, the pivot mechanism is arranged on the gantry support relative to this vertically adjustable. As a result, the angle β is changeable. Since the size of the angle β has an immediate influence on the magnitude of the compressive force, an individual adjustment can thus be made.

Die in der Zeichnung dargestellte Vorrichtung dient zum Trennen bzw. Schneiden von Scheiben von einem Tabakballen. Die Erfindung betrifft jedoch in gleicher Weise eine Vorrichtung zum Trennen von Scheiben von einem Ballen, der aus anderen in der Tabak verarbeitenden Industrie verwendeten Materialien oder Materialmischungen besteht.The device shown in the drawing is used for separating or cutting of slices of a tobacco bale. However, the invention equally relates to a device for separating slices from a bale made of other materials or blends of materials used in the tobacco processing industry.

In den Figuren 1 bis 11 ist eine Vorrichtung 10 in unterschiedlichen Ansichten und Positionen gezeigt, die zum automatischen Trennen von Scheiben 11 von einem Tabakballen 12 ausgebildet und eingerichtet ist. Die Vorrichtung 10 umfasst ein Zuführelement 13 zum Zuführen eines Tabakballens 12 in Transportrichtung T in Richtung des Wirkbereichs eines Trennmessers, das Trennmesser 14, einen in Transportrichtung T hinter dem Zuführelement 13 angeordneten Schneidtisch 15 sowie eine oberhalb des Schneidtisches 15 angeordnete Gegenhalteplatte 16. Die Oberflächen des Zuführelementes 13 und des Schneidtisches 15 liegen in derselben Ebene. Genauer liegt die Auflagefläche 17 des Zuführelementes 13 für den Tabakballen 12 in derselben Ebene wie die Auflagefläche18 des Schneidtisches 15 für den Abschnitt des Tabakballens 12, der die zu schneidende bzw. geschnittene Scheibe 11 bildet. Dem Schneidtisch 15 ist ein (nicht explizit dargestelltes) Antriebsmittel zum linearen Verfahren in Transportrichtung T von dem Zuführelement 13 weg und entgegen der Transportrichtung T auf das Zuführelement 13 zu zugeordnet. Anders ausgedrückt ist der Schneidtisch 15 in Verlängerung des Zuführelementes 13 in einer horizontalen Ebene hin und her verfahrbar, so dass der Abstand zwischen dem Zuführelement 13 und dem Schneidtisch 15 veränderbar ist. Die Gegenhalteplatte 16 ist ebenfalls entgegen der Transportrichtung T und in Transportrichtung T bewegbar ausgebildet, Die Gegenhalteplatte 16 steht im Wesentlichen senkrecht zum Schneidtisch 15. Genauer verläuft die Ebene, die durch die Anlagefläche 19 der Gegenhalteplatte 16 an der zu schneidenden bzw. geschnittenen Scheibe 11 aufgespannt wird, senkrecht zur Ebene, die durch die Auflagefläche 18 des Schneidtisches 15 aufgespannt wird und quer zur Transportrichtung T. Das Trennmesser 14 ist derart angeordnet, dass es zwischen dem Zuführelement 13 und dem Schneidtisch 15 eintauchen kann.In the FIGS. 1 to 11 For example, a device 10 is shown in various views and positions that is configured and arranged to automatically separate slices 11 from a tobacco bale 12. The device 10 comprises a feed element 13 for feeding a tobacco bale 12 in the transport direction T in the direction of the effective range of a separating knife, the severing knife 14, a downstream of the feed element 13 arranged in the transport direction T cutting table 15 and disposed above the cutting table 15 counter holding plate 16. Die Oberflächen des Feeding element 13 and the cutting table 15 lie in the same plane. More precisely, the support surface 17 of the feed element 13 for the tobacco bale 12 lies in the same plane as the support surface 18 of the cutting table 15 for the portion of the tobacco bale 12 forming the slice 11 to be cut or cut. The cutting table 15 is associated with a (not explicitly shown) drive means for the linear process in the transport direction T of the feed 13 away and opposite to the transport direction T to the feed element 13 to. In other words, the cutting table 15 can be moved back and forth in an extension of the feed element 13 in a horizontal plane, so that the distance between the feed element 13 and the cutting table 15 is variable. The counter-holding plate 16 The counter-holding plate 16 is substantially perpendicular to the cutting table 15. More specifically, the plane which is spanned by the abutment surface 19 of the counter-holding plate 16 on the cut or cut slice 11, perpendicular to the plane which is spanned by the bearing surface 18 of the cutting table 15 and transversely to the transport direction T. The separating blade 14 is arranged such that it can dip between the feed element 13 and the cutting table 15.

Diese Vorrichtung 10 zeichnet sich erfindungsgemäß dadurch aus, dass die Gegenhalteplatte 16 antriebslos ausgebildet und passiv entlang horizontal gerichteter Linearführungen 20, 21 in und entgegen der Transportrichtung T bewegbar ist. Anders ausgedrückt ist die Gegenhalteplatte 16 entlang ihrer Linearführungen 20, 21 grundsätzlich frei hin und her schieb,- drück- oder ziehbar. Das bedeutet, dass die Gegenhalteplatte 16 passiv bzw. indirekt bewegbar ist. Die gezielten bzw. gerichteten Bewegungen der Gegenhalteplatte 16 in und entgegen der Transportrichtung T hängen ausschließlich von mechanischen, antriebs(-motor)freien Komponenten und/oder Antriebsmitteln anderer Komponenten ab, indem die Antriebsmittel der anderen Komponenten - zur Reduzierung der Anzahl von Antriebsmitteln der Vorrichtung 10 insgesamt - mindestens teilweise eine Doppelfunktion übernehmen.This device 10 is inventively characterized in that the counter-holding plate 16 is formed without drive and passively along horizontally oriented linear guides 20, 21 in and against the transport direction T is movable. In other words, the counter-holding plate 16 is basically free to slide back and forth along its linear guides 20, 21, - can be pushed or pulled. This means that the counter-holding plate 16 is passively or indirectly movable. The targeted or directed movements of the counter-holding plate 16 in and against the transport direction T depend exclusively on mechanical, drive (-motor) free components and / or drive means of other components, by the drive means of the other components - to reduce the number of drive means of the device 10 in total - at least partially take on a dual function.

Die im Folgenden beschriebenen Merkmale und Weiterbildungen stellen für sich betrachtet oder in Kombination miteinander bevorzugte Ausführungsformen dar. Es wird ausdrücklich darauf hingewiesen, dass Merkmale, die in den Ansprüchen und/oder der Beschreibung zusammengefasst oder in einer gemeinsamen Ausführungsform beschrieben sind, auch funktional eigenständig die weiter oben beschriebene Vorrichtung 10 weiterbilden können.The features and developments described below represent individually or in combination with each other preferred embodiments. It is expressly understood that features that are summarized in the claims and / or the description or described in a common embodiment, also functionally independent the can further develop device 10 described above.

Das Zuführelement 13 kann ein einfacher Tisch mit einer Anordnung zum Transportieren des Tabakballens 12 sein. Optional kann das Zuführelement 13 auch ein Förderelement, Förderband oder dergleichen sein. Die konstruktive Ausgestaltung ist variabel. Entscheidend ist die Ausbildung zum gesteuerten und vorzugsweise getakteten Zuführen des Tabakballens 12 in Transportrichtung T. Mittels Wegmesssystemen kann der Vorschub ermittelt und über geeignete Steuerungsmittel gesteuert werden, um beispielsweise Scheiben 11 unterschiedlicher Dicke schneiden zu können.The feed element 13 may be a simple table with an arrangement for transporting the tobacco bale 12. Optionally, the feed element 13 may also be a conveyor element, conveyor belt or the like. The structural design is variable. Decisive is the training for controlled and preferably clocked feeding the tobacco bale 12 in the transport direction T. By means of displacement measuring systems, the feed can be determined and controlled by suitable control means, for example, to be able to cut slices 11 of different thickness.

Das Trennmesser 14 ist vorzugsweise ein guillotinenartiges Messer, das vertikal von oben nach unten und zurück, und senkrecht zur Transportrichtung T beispielsweise mittels eines Kettenantriebs oder dergleichen, bewegbar an einem Portalträger 22 ausgebildet ist. Der Portalträger 22 kann beispielsweise zwei Vertikalstützen 23, 24 sowie eine Querstütze 25 umfassen. Der Portalträger 22 bildet zusammen mit dem Trennmesser 14, dem Schneidtisch 15 und der Gegenhalteplatte 16 vorzugsweise ein Schneidportal 26. Das Trennmesser 14 kann aber auch als oszillierendes Bandmesser oder Schwenkmesser ausgebildet sein. Das Trennmesser 14 kann des Weiteren auch seitlich bewegbar ausgebildet sein, derart, dass die Scheiben 11 quer zur Transportrichtung T des Tabakballens 12 getrennt werden können. Anstelle des Portalträgers 22 können auch andere Rahmengestellt, Gehäusewände oder dergleichen zur Aufnahme bzw. Lagerung des Trennmessers 14 und anderer Komponenten eingesetzt werden.The separating knife 14 is preferably a guillotine-like knife, which is formed vertically from top to bottom and back, and perpendicular to the transport direction T, for example by means of a chain drive or the like, movable on a gantry 22. The gantry carrier 22 may comprise, for example, two vertical supports 23, 24 and a transverse support 25. The gantry carrier 22 together with the cutting knife 14, the cutting table 15 and the counter-holding plate 16 preferably a cutting portal 26. The cutting knife 14 may also be formed as an oscillating band knife or swivel knife. The separating knife 14 may further be formed laterally movable, such that the discs 11 can be separated transversely to the transport direction T of the tobacco bale 12. Instead of the gantry carrier 22, other frameworks, housing walls or the like can be used for receiving or supporting the separating blade 14 and other components.

Vorzugsweise ist der Schneidtisch 15 entlang horizontal gerichteter Linearführungen 27, 28 parallel zur Gegenhalteplatte 16 aktiv aus einer geöffneten Freigabestellung (siehe z.B. Figur 5) in eine geschlossene Schneidstellung (siehe z.B. Figur 6), in der zwischen dem Zuführelement 13 und dem Schneidtisch 15 ein Spalt 29 zum Durchtritt des Trennmessers 14 gebildet ist, und umgekehrt verfahrbar. Der Gegenhafteplatte 16 ist zum Bewegen entgegen der Transportrichtung T ein gewichtsbelasteter Schwenkmechanismus 30 zugeordnet ist, der permanent an der Gegenhalteplatte 16 anliegt und eine Druckkraft F auf die Gegenhalteplatte 16 ausübt, die der Transportrichtung T entgegenwirkt. Zum Bewegen der Gegenhalteplatte 16 in Transportrichtung T ist diese mit dem angetriebenen Schneidtisch 15 mittels eines Anschlag- und Mitnehmermittels 31 in Wirkverbindung bringbar ist.Preferably, the cutting table 15 is active along horizontally oriented linear guides 27, 28 parallel to the counter-holding plate 16 from an open release position (see eg FIG. 5 ) in a closed cutting position (see eg FIG. 6 ), in which between the feed element 13 and the cutting table 15, a gap 29 is formed for the passage of the separating blade 14, and vice versa movable. The counter-covering plate 16 is associated with a weight-loaded pivoting mechanism 30 for moving against the transporting direction T, which bears permanently against the counter-holding plate 16 and exerts a compressive force F on the counter-holding plate 16, which counteracts the transporting direction T. To move the counter-holding plate 16 in the transport direction T, it can be brought into operative connection with the driven cutting table 15 by means of a stop and entrainment means 31.

Dieses kombinierte Anschlag- und Mitnehmermittel 31 ist vorzugsweise dem Schneidtisch 15 zugeordnet. Mit diesem Anschlag- und Mitnehmermittel 31 sind der Schneidtisch 15 und die Gegenhalteplatte 16 in Wirkverbindung bringbar, derart, dass der Schneidtisch 15 bzw. das Anschlag- und Mitnehmermittel 31 einerseits die Bewegung der Gegenhalteplatte 16 entgegen der Transportrichtung T begrenzen und andererseits eine Bewegung der Gegenhalteplatte 16 in Transportrichtung T bewirken kann. Anders ausgedrückt hält der Schneidtisch 15 die Gegenhalteplatte 16, die grundsätzlich durch den auf die Gegenhalteplatte 16 wirkenden Schwenkmechanismus 30 den Drang hat, entgegen der Transportrichtung Z in die maximale Frontposition bewegt zu werden, in bestimmten Positionen über das Anschlag- und Mitnehmermittel 31 fest (siehe z.B. Figur 5). In einer anderen Position (siehe z.B. Figuren 9 und 10) nimmt der Schneidtisch 15 die Gegenhalteplatte 16 über das Anschlag- und Mitnehmermittel 31 in Transportrichtung T mit.This combined stop and entrainment means 31 is preferably associated with the cutting table 15. With this stop and entrainment means 31, the cutting table 15 and the counter-holding plate 16 can be brought into operative connection, such that the cutting table 15 or the stop and entrainment means 31 on the one hand limit the movement of the counter-holding plate 16 against the transport direction T and, on the other hand, a movement of the counter-holding plate 16 in the transport direction T can effect. In other words, the cutting table 15 holds the counter-holding plate 16, which in principle has the urge, by the pivot mechanism 30 acting on the counter-holding plate 16, against the transport direction Z to the maximum front position to be moved, in certain positions on the stop and catch means 31 fixed (see, eg FIG. 5 ). In another position (see eg FIGS. 9 and 10 ) takes the cutting table 15, the counter-holding plate 16 via the stop and entrainment means 31 in the transport direction T.

Die lineare Bewegbarkeit der Gegenhalteplatte 16 entgegen der Transportrichtung T ist in einer Position unmittelbar vor dem Trennmesser 14 und in Transportrichtung T jeweils durch ein unabhängig vom Schneidtisch 15 wirkendes, zusätzliches Anschlagelement 32, 33 begrenzbar. Beim Bewegen des Schneidtisches 15 in die Schneidposition (siehe z.B. Figur 6) bleibt die Gegenhalteplatte 16 durch den Anschlag 32, der separat vom Schneidtisch 15 ausgebildet und vorzugsweise der Gegenplatte 16 selbst zugeordnet ist, vor dem Trennmesser 14 stehen. In dem gezeigten Ausführungsbeispiel ist das Anschlagelement 32 integraler Bestandteil der Gegenhalteplatte 16, wobei sich das Anschlagelement 32 z.B. an den Vertikalstützen 23, 24 des Portalträgers 22 abstützen kann. Das Anschlagelement 33 dient zur Begrenzung der linearen Bewegung der Gegenhalteplatte 16 in Transportrichtung T, um ein Widerlager zu bilden für den z.B. in Figur 11 dargestellten Sonderfall, dass die abgetrennte Scheibe 11 auf dem Schneidtisch 15 verbleibt und durch Relativbewegung zwischen Schneidtisch 15 und Gegenhalteplatte 16 vom Schneidtisch 15 geschoben werden soll.The linear mobility of the counter-holding plate 16 against the transport direction T can be limited in a position immediately in front of the separating knife 14 and in the transport direction T by an additional stop element 32, 33 acting independently of the cutting table 15. When moving the cutting table 15 in the cutting position (see, eg FIG. 6 ) remains the counter-holding plate 16 by the stop 32, which is formed separately from the cutting table 15 and preferably the counter-plate 16 is assigned itself, stand in front of the cutting blade 14. In the embodiment shown, the stop element 32 is an integral part of the counter-holding plate 16, wherein the stop element 32 can be supported, for example, on the vertical supports 23, 24 of the gantry carrier 22. The stop member 33 serves to limit the linear movement of the counter-holding plate 16 in the transport direction T, to form an abutment for example in FIG. 11 illustrated special case that the separated disc 11 remains on the cutting table 15 and is to be pushed by relative movement between the cutting table 15 and counter-holding plate 16 from the cutting table 15.

Der Schwenkmechanismus 30 ist an dem Portalträger 22 angeordnet, an dem auch das Trennmesser 14 vertikal auf und ab bewegbar angeordnet ist. Der Schwenkmechanismus 30 ist um eine Achse I schwenkbar, und zwar vorzugsweise zwischen den beiden Vertikalstützen 23, 24 des Portalträgers 22. Die Achse I ist quer zur Transportrichtung T ausgerichtet und weist einen Abstand zum Schneidtisch 15 auf, der größer als die Höhe des zu schneidenden Tabakballens 12 ist. Der Schwenkmechanismus 30 umfasst einen Schwenkhebel 34 und einen fest mit diesem verbundenen Stützhebel 35, der in der gezeigten Ausführungsform etwa in einem rechten Winkel α zum Schwenkhebel 34 ausgerichtet ist. Allerdings kann der Winkel a zwischen dem Schwenkhebel 34 und dem Stützhebel 35 auch größer oder kleiner ausgebildet sein. Schwenkhebel 34 und Stützhebel 35 bilden bevorzugt eine starre Einheit. Der Schwenkhebel 34 kann drehbar an bzw. auf einer Querstrebe 36 des Portalträgers 22 gelagert sein. Optional kann der Schwenkhebel 34 auch fest mit der Querstrebe 36 verbunden sein, die ihrerseits drehbar am Portalträger 22 gelagert ist. Der Stützhebel 35 liegt mit seinem freien Ende 37 lose an der Gegenhalteplatte 16 an. Dadurch, dass der Schwenkmechanismus 30 um die Achse I schwenkbar ist, ist das freie Ende 37 des Stützhebels 35 bei jeder Auslenkung einer vertikalen Bewegungskomponente ausgesetzt. Diese gilt es auszugleichen, indem der Stützhebel 35 relativ zur Gegenhalteplatte 16 bewegbar ist. Besonders bevorzugt sind am freien Ende 37 des Stützhebels 35 zum Ausgleich der Schwenkbewegung des Schwenkhebels 34 Rollen 38 zum vertikalen Abrollen des Schwenkmechanismus 30 entlang der Gegenhalteplatte 16 angeordnet. Anstelle der Rollen 38 können jedoch auch Gleitstücke oder andere eine Relativbewegung zulassende oder unterstützende Komponenten eingesetzt werden. Es besteht auch die Möglichkeit, dass die Gegenhalteplatte 16 auf der dem Tabakballen 12 abgewandten Seite Linearführungen z.B. in Form von Nuten aufweist, in denen Gleitschuhe oder dergleichen zwangsgeführt auf und ab gleiten können.The pivot mechanism 30 is arranged on the gantry carrier 22, on which also the separating knife 14 is arranged vertically movable up and down. The pivot mechanism 30 is pivotable about an axis I, preferably between the two vertical supports 23, 24 of the gantry 22. The axis I is oriented transversely to the transport direction T and has a distance from the cutting table 15, which is greater than the height of the cut Tobacco bale 12 is. The pivoting mechanism 30 comprises a pivoting lever 34 and a fixedly connected thereto support lever 35 which is aligned in the illustrated embodiment approximately at a right angle α to the pivot lever 34. However, the angle a between the pivot lever 34 and the support lever 35 may be formed larger or smaller. Pivot lever 34 and support lever 35 preferably form a rigid unit. The pivot lever 34 may be rotatably mounted on or on a transverse strut 36 of the gantry 22. Optionally, the pivot lever 34 may also be fixedly connected to the transverse strut 36, which in turn is rotatably mounted on the portal support 22. The support lever 35 rests with its free end 37 loosely against the counter-holding plate 16. Characterized in that the pivot mechanism 30 is pivotable about the axis I, the free end 37 of the support lever 35 is exposed at each deflection of a vertical movement component. This is compensated by the support lever 35 is movable relative to the counter-holding plate 16. Particularly preferably, at the free end 37 of the support lever 35 to compensate for the pivotal movement of the pivot lever 34 rollers 38 for vertical rolling of the pivot mechanism 30 along the counter-holding plate 16 is arranged. However, instead of the rollers 38, it is also possible to use sliders or other components which permit or support a relative movement. There is also the possibility that the counter-holding plate 16 on the side facing away from the tobacco bale 12 has linear guides, for example in the form of grooves, in which sliding shoes or the like can forcibly slide up and down.

Der Schwenkmechanismus 30 ist ein Gestell, das mittels seines Eigengewichts und durch die Hebelgeometrie von Schwenkhebel 34 und Stützhebel 35 die Druckkraft F auf die Gegenhalteplatte 16 aufbringt. Der Schwenkhebel 34 kann z.B. eine Platte sein. In einer bevorzugten Ausführungsform umfasst der Schwenkhebel 34 zwei beanstandet zueinander angeordnete und parallel verlaufende Streben 39, 40, die mit einer Querstrebe 41 miteinander verbunden sind. Der Stützhebel 35 kann ebenfalls eine Platte sein, umfasst bevorzugt jedoch ebenfalls zwei Streben 42, 43, die sich in dem zuvor beschriebenen Winkel α jeweils an eine der Streben 39, 40 anschließen. Um eine höhere Druckkraft F auf die Gegenhalteplatte 16 aufbringen zu können, kann der Schwenkmechanismus 30 zusätzlich zum Schwenkhebel 34 und Stützhebel 35 bzw. zu deren Eigengewicht mindestens ein Zusatzgewicht 44 umfassen. Das Zusatzgewicht 44 ist bevorzugt an der Querstrebe 41 befestigt. Das Zusatzgewicht 44 kann aber an jeder Position des Schwenkmechanismus 30 angeordnet sein. Besonders bevorzugt ist das Zusatzgewicht 44 lösbar und damit austauschbar am Schwenkmechanismus 30 befestigt. Der horizontale Abstand zwischen der Achse I und dem Zusatzgewicht 44 ist der maßgebliche Abstand für die Größe der Druckkraft F.The pivot mechanism 30 is a frame that applies the pressure force F to the counter-holding plate 16 by its own weight and by the lever geometry of pivot lever 34 and support lever 35. The pivoting lever 34 may e.g. to be a plate. In a preferred embodiment, the pivot lever 34 comprises two mutually spaced and parallel struts 39, 40, which are connected to one another with a transverse strut 41. The support lever 35 may also be a plate, but preferably also comprises two struts 42, 43, which in the above-described angle α in each case to one of the struts 39, 40 connect. In order to be able to apply a higher compressive force F to the counter-holding plate 16, the pivoting mechanism 30 may comprise at least one additional weight 44 in addition to the pivoting lever 34 and the supporting lever 35 or to its own weight. The additional weight 44 is preferably fastened to the transverse strut 41. However, the additional weight 44 may be arranged at any position of the pivot mechanism 30. Particularly preferably, the additional weight 44 is releasably secured and thus exchangeable on the pivot mechanism 30. The horizontal distance between the axis I and the additional weight 44 is the relevant distance for the magnitude of the compressive force F.

Der Schwenkmechanismus 30 ist in der dargestellten Ausführungsform ortsfest am Portalträger 22 angeordnet. In einer bevorzugten Weiterbildung kann der Schwenkmechanismus 30 am Portalträger 22 aber auch relativ zu diesem vertikal verstellbar angeordnet sein, beispielsweise in Linearführungen entlang der Vertikalstützen 23, 24. In weiteren bevorzugten Weiterbildungen der Erfindung können die weiter oben beschriebenen Anschlagelemente 32, 33 fest oder verstellbar ausgebildet sein. Die Anschlagelemente können z.B. aus einer Freigabeposition in die Anschlagposition und zurück bewegbar ausgebildet sein. Die Anschlagelemente 32, 33 können auch bezüglich ihrer Anschlagposition verstellbar sein, indem z.B. das Anschlagelement 33 zur Begrenzung der linearen Bewegung der Gegenhalteplatte 16 in Transportrichtung T auf der Linearführung 20, 21 verstellbar angeordnet ist.The pivot mechanism 30 is arranged in a stationary manner on the gantry carrier 22 in the illustrated embodiment. In a preferred embodiment, the pivot mechanism 30 on the gantry support 22 but also be arranged vertically adjustable relative to this, for example in linear guides along the vertical supports 23, 24. In further preferred embodiments of the invention can the abutment elements 32, 33 described above may be formed fixed or adjustable. The stop elements may be formed, for example, from a release position in the stop position and movable back. The stop elements 32, 33 can also be adjusted with respect to their stop position, for example by the stop element 33 for limiting the linear movement of the counter-holding plate 16 in the transport direction T on the linear guide 20, 21 is arranged adjustable.

Der Vorrichtung 10 kann des Weiteren ein Leitelement 45 zugeordnet sein, mittels dem die vom Tabakballen 12 abgeschnittenen Scheiben 11 zur weiteren Verarbeitung umgelenkt bzw. aus der Vorrichtung 10 gelenkt werden können. Die Vorrichtung 10 kann des Weiteren eine Steuerung umfassen, mittels der die Antriebe für den Tabakballentransport, das Trennmesser und den Schneidtisch sowie vorhandene Detektionsmittel, wie z.B. Lichtschranken oder dergleichen, aufeinander abgestimmt gesteuert werden können.The device 10 may further be assigned a guide element 45, by means of which the slices 11 cut off from the tobacco bale 12 can be deflected for further processing or be guided out of the device 10. The apparatus 10 may further comprise a controller by means of which the tobacco bale transport drives, the cutting knife and the cutting table, as well as existing detection means, such as e.g. Photocells or the like, can be controlled to match.

Der Ablauf des Trennens einer Scheibe 11 vom Tabakballen wird im Folgenden anhand der Figuren 5 bis 10 beschrieben.
In der Grundstellung (siehe Figur 5) ist der Schneidtisch 15 offen, d.h. in einer Position, in der der Schneidtisch 15 mit großem Abstand zum Zuführelement 13 steht. Der Schneidtisch 15 hält über das Anschlag- und Mitnehmermittel 31 die Gegenhalteplatte 16 ebenfalls in der offenen Position. Wenn eine Scheibe 11 vom Tabakballen 12 geschnitten werden soll, wird der Schneidtisch 15 geschlossen. Das bedeutet, dass der Schneidtisch 15 entgegen der Transportrichtung T auf das Zuführelement 13 zu bewegt wird, und zwar bis fast unter das Trennmesser 14. Anders ausgedrückt wir der Schneidtisch 15 soweit an das Zuführelement 13 vorgefahren, bis zwischen dem Zuführelement 13 und dem Schneidtisch 15 nur noch der Spalt 29 frei ist. Die Gegenhalteplatte 16 wird durch die Druckkraft F ebenfalls entgegen der Transportrichtung T gedrückt, bleibt aber vor dem Trennmesser 14 stehen, da das Anschlagelement 32, das gegen den Portalträger 22 stößt, eine weitere Bewegung stoppt. Der Schneidtisch 15 fährt unter der Gegenhalteplatte 16 weiter bis zu der weiter oben beschriebenen End- bzw. Schneidposition (siehe Figur 6).The sequence of separating a disc 11 from the tobacco bale will be described below with reference to FIGS. 5 to 10 described.
In the basic position (see FIG. 5 ), the cutting table 15 is open, ie in a position in which the cutting table 15 is at a great distance from the feed element 13. The cutting table 15 holds on the stop and entrainment means 31, the counter-holding plate 16 also in the open position. When a slice 11 is to be cut from the tobacco bale 12, the cutting table 15 is closed. This means that the cutting table 15 is moved counter to the transport direction T to the feed element 13, and almost to the cutting knife 14. In other words, the cutting table 15 as far advanced to the feed element 13 until between the feed element 13 and the cutting table 15th only the gap 29 is free. The counter-holding plate 16 is also pressed against the transport direction T by the pressing force F, but remains in front of the separating knife 14, since the stop element 32, which abuts against the gantry carrier 22, stops further movement. The cutting table 15 continues under the counter-holding plate 16 to the end or cutting position described above (see FIG. 6 ).

Der Tabakballen 12 wird dann aktiv in Transportrichtung T transportiert und schiebt die Gegenhalteplatte 16 zurück auf die endgültige Position zum Schneiden. Diese Position bestimmt die Slicedicke (siehe Figur 7). Beim Trennen bzw. Schneiden der Scheibe 11 vom Tabakballen 12 kann die Gegenhalteplatte 16 nach hinten in Transportrichtung T ausweichen, um Platz für das Trennmesser 14 zu schaffen (siehe Figur 8). Nach dem Schneiden fährt der Schneidtisch 15 in Transportrichtung T zurück in die offene Position und nimmt gleichzeitig über das Anschlag- und Mitnehmermittel 31 die Gegenhalteplatte 16 mit zurück. Die abgeschnittene Scheibe 11 fällt nach unten auf das Leitelement 45 und wird aus der Vorrichtung 10 geführt (siehe Figuren 9 und 10). Anschließend beginnt der Trennzyklus von vorne, indem der Schneidtisch 15 wieder in die geschlossene Position fährt.The tobacco bale 12 is then actively transported in the transport direction T and pushes the counter-holding plate 16 back to the final position for cutting. This position determines the slit thickness (see FIG. 7 ). When separating or cutting the disc 11 from the tobacco bale 12, the counter-holding plate 16 to the rear in the transport direction T. Dodge to make room for the separating knife 14 (see FIG. 8 ). After cutting the cutting table 15 moves back in the transport direction T in the open position and at the same time takes over the stop and catch means 31, the counter-holding plate 16 back. The cut-off disc 11 drops down onto the guide element 45 and is guided out of the device 10 (see FIG FIGS. 9 and 10 ). Subsequently, the separation cycle starts from the front by the cutting table 15 moves back to the closed position.

In der Figur 11 ist ein Sonderfall dargestellt, bei dem sich die bereits abgetrennte Scheibe 11 auch beim Verfahren in die offene Position auf dem Schneidtisch 15 befindet. Für diesen Sonderfall kann die Scheibe 11 vom Schneidtisch 15 geschoben werden, indem die Gegenhalteplatte 16 durch das Anschlagelement 33 am Bewegen in Transportrichtung T gehindert wird, so dass der Schneidtisch 15 quasi unter der Gegenhalteplatte 16 weggezogen wird, bis die Scheibe 11 dann nach unten zur weiteren Verarbeitung fallen kann.In the FIG. 11 is a special case shown, in which the already separated disc 11 is also in the process in the open position on the cutting table 15. For this special case, the disc 11 can be pushed by the cutting table 15 by the counter-holding plate 16 is prevented by the stop member 33 from moving in the transport direction T, so that the cutting table 15 is pulled away from below virtually the counter-plate 16 until the disc 11 then down to further processing.

In den Figuren wird das Schneiden von Scheiben 11 einer bestimmten Dicke beschrieben. Durch die Wahl der Größe des Vorschubs des Tabakballens 12 in Transportrichtung T, die z.B. durch Detektionsmittel ermittelt und/oder bestimmt werden kann, kann die Dicke der Scheiben 11 (Slicedicke) variiert werden. Mit zunehmender Slicedicke steigt entsprechend das Gewicht der Scheiben 11. Je größer die Dicke der Scheiben 11 ist, desto mehr wird die Gegenhalteplatte 16 ausgelenkt, wodurch sich der Winkel β und damit die horizontal wirkende Kraftkomponente vergrößert. Durch den größer werdenden Winkel β steigt somit die Gegenhaltekraft, nämlich die Druckkraft F, an.In the figures, the cutting of slices 11 of a certain thickness is described. By selecting the size of the feed of the tobacco bale 12 in the transporting direction T, e.g. determined and / or determined by detection means, the thickness of the slices 11 (slit thickness) can be varied. As the slicing thickness increases, the weight of the disks 11 correspondingly increases. The greater the thickness of the disks 11, the more the counter-holding plate 16 is deflected, as a result of which the angle β and thus the horizontally acting force component increase. Due to the increasing angle β thus the counter-holding force, namely the pressure force F, increases.
