Definitions
- the invention relates to a tobacco cutting device with a device for grinding a separating knife of the tobacco cutting device with the features of the preamble of claim 1.
- the tobacco is fed to the tobacco cutting device in the form of a compacted tobacco tobacco tobacco tobacco blended as needed with tobacco sauce.
- the tobacco cutting device comprises, inter alia, a driven knife carrier drum, on whose lateral surface or end face one or more cutting blades are arranged, which are periodically passed during the movement of the knife carrier drum on the mouthpiece of the tobacco cake supplied and thereby separating the tobacco fibers in thin strips of the tobacco pee.
- the cutting blades of the tobacco cutting device are subject to unavoidable wear and unavoidable contamination during the cutting process by the supplied tobacco cake.
- the reason for the wear and the contamination of the separating blades are essentially hard particles in the tobacco cake and the tobacco sauce present in the tobacco cake or the tobacco dust produced when cutting the tobacco cake.
- the cutting blades In order for this wear or contamination of the cutting knife does not adversely affect the quality of cut, the cutting blades must be regularly reground and tracked.
- the cutting blades are appropriate facilities with a grinding wheel from eg cubic boron nitride (CBN) or corundum provided, which in turn is inevitably worn during the grinding process of the cutting blade and / or contaminated by the contamination of the cutting blade.
- CBN cubic boron nitride
- the abrasive body itself In order for this wear and / or contamination of the grinding wheel in turn does not adversely affect the grinding of the cutting blade, the abrasive body itself must be dressed and / or cleaned evenly at regular intervals, the dressing and cleaning can also be done in a single machining operation of the grinding wheel.
- the grinding surface of the grinding wheel is pulled off, for example by means of a diamond, or cut or machined by means of a high-energy laser beam.
- Such dressing can be omitted when using cubic boron nitride abrasives, provided that the wear of this material is so low that it does not significantly deteriorate the grinding quality.
- Cleaning of the abrasive article is imperative due to the adhering tobacco sauce and the adhering tobacco dust, regardless of the base material of the abrasive article, for a high quality grinding operation of the cutting blades to maintain the cut quality.
- a device in which the abrasive body is arranged in a conditioning chamber which is arranged in a fixed spatial relationship to the knife carrier drum on the circumference of the cutting circle of the cutting knife and encapsulates the abrasive body outside the cutting circle of the cutting knife.
- the abrasive article is cleaned in the conditioning chamber by means of a cleaning jet from a liquid or gaseous medium. Since the grinding body for grinding the cutting blades must at least affect the cutting circle with its peripheral surface, an opening in the conditioning chamber is provided in this solution, through which the abrasive article protrudes outward. The opening is in turn closed for cleaning the abrasive article by means of a separate closing element to completely encapsulate the abrasive body and to prevent contamination of the environment or endangerment of the person handling during the cleaning process.
- the object of the invention is to provide a tobacco cutting device with a device for grinding a cutting knife of the tobacco cutting device, which should be structurally simple as possible, and in the dressing and / or cleaning of the abrasive body with the least possible contamination of the product to be cut and / or Endangerment of the environment or the person handling should be possible.

- the advantage of the proposed solution is the fact that the product area in which the tobacco fibers are cut from the tobacco cake, by the proposed arrangement of the conditioning chamber and the movement of the grinding wheel spatially clearly separated from the area in which the abrasive article is cleaned and / or dressed. This can significantly reduce the likelihood of contamination of the product. Furthermore, since the conditioning chamber no longer has to be arranged on the circumference of the knife carrier drum and therefore does not have to be adapted constructively to the operating position of the grinding wheel or to the geometry of the knife carrier drum, it can be made considerably simpler in terms of tightness and increased safety. Overall, the grinding process can be realized by the proposed arrangement of the conditioning significantly cheaper and safer in terms of the specified requirements.
- the abrasive body is movable parallel to the axis of rotation of the knife carrier drum in the conditioning chamber, so that the position of the abrasive body during the Method alone is changed in one axis, and the orientation of the grinding wheel in the direction of the other two axes is not changed.
- one and the same conditioning chamber can be used for dressing and / or cleaning abrasive articles of different tobacco cutting devices with different knife carrier drums.
- a temperature sensor device and / or a feed device for supplying a cleaning and / or extinguishing agent and / or a cleaning laser for cleaning the grinding wheel and / or a suction device is provided on the conditioning chamber.
- the temperature sensor device in particular, the temperature of the abrasive body, e.g. during dressing, so that the dressing is interrupted or slowed down when a predetermined temperature is exceeded.
- the structural separation of the conditioning chamber from the knife carrier drum can simplify the supply of a cleaning or extinguishing agent and / or a cleaning laser and / or a suction device to the conditioning chamber.
- further devices for improving the dressing and / or grinding of the grinding body can be provided.
- the conditioning chamber has a closable by means of a closing device opening through which the grinding body is retractable into the conditioning chamber.
- the opening is arranged on the side of the conditioning chamber, which faces the knife carrier drum, so that the grinding body can be moved into the conditioning chamber in a linear, uniaxial movement parallel to the direction of the axis of rotation of the knife carrier drum.
- the conditioning chamber may also comprise a two-part housing having a first and a second part, wherein the first and the second part of the housing are separated in the operating position of the grinding body, and at least one of the parts of the housing by the movement of the grinding body from the Operating position in the conditioning chamber controlled movement performs, through which the two parts of the housing come to rest against each other.
- the conditioning chamber is completed by the completion of the parts of the housing only fully closed when the grinding wheel is moved out of the operating position.
- the movement of the parts of the housing is deliberately controlled by the movement of the abrasive body, so that the movements are coupled and the complete closing of the housing takes place only when the grinding body has been arranged in a certain position or entered a certain spatial section.
- the first part of the housing is fixedly arranged on the tobacco cutting device, and the second part of the housing is coupled in terms of movement with the grinding body.
- the movement can be particularly easily realized by the first part of the housing is fixed and the second part to complete the housing is moved to the first part of the housing.
- the second part of the housing may also be fixedly formed with a carrier of the abrasive body, so that the second part of the housing is moved together with the grinding body.
- the second part practically forms a hood, which is moved together with the grinding body relative to the knife carrier drum.
- the first part of the housing may be fixedly arranged on the tobacco cutting device and the second part of the housing form the closing device of the opening.
- the grinding body can then be retracted through the opening in the first part of the housing, which is then closed during the further retraction by the second part of the housing fixedly connected to the carrier of the grinding body.
- the grinding body can be driven by means of a drive device for grinding the separating knife in different operating positions to a parallel to the axis of rotation of the knife carrier drum directed movement, and the grinding body by means of the same drive means for carrying out the movement into the conditioning chamber is drivable.
- Such movement of the abrasive article to various operating positions may be e.g. be provided when the width of the abrasive body is smaller than the width of the cutting blade.
- the grinding body can be moved continuously or at intervals along the axis of rotation of the knife carrier drum during grinding or during the rotation of the knife carrier drum, so that the separating knife or blades are reground at different points in its longitudinal direction.
- This drive device can be used in this case due to the proposed direction of the movement in the conditioning chamber at the same time also for moving the grinding body in the conditioning chamber.
- Both tobacco cutting devices each have a knife carrier drum 1, and a conveyor 4, through which a compressed tobacco cake 5 is supplied.
- the tobacco cake 5 is formed of compressed tobacco fibers, which may be mixed with a tobacco sauce as needed.
- On the knife carrier drum 1 two cutting blades 2 protruding obliquely from the lateral surface of the knife carrier drum 1 are provided, the cut edges of which define a separating circle 16 when circulating the knife carrier drum 1 and separate each tobacco fiber in thin strips from a mouthpiece 17 of the tobacco cake 5.
- an abrasive body 3 is provided, on which the cut edges of the separating knife 2 are guided past during regrinding for regrinding.
- the grinding body 3 is formed by a driven grinding wheel, which is driven in the opposite direction to the rotational movement of the knife carrier drum 1 about an axis of rotation 7 aligned parallel to the axis of rotation 6 of the knife carrier drum 1.

- the movement of the grinding wheel 3 can be provided for grinding the cutting blade 2 over its longitudinal axis, but is also used according to the invention for moving the grinding wheel 3 into the conditioning chamber 8 arranged at the left end side of the knife carrier drum 1.
- the traversing movement of the grinding wheel 3 is a linear uniaxial movement parallel to the longitudinal direction of the lateral surface of the knife carrier drum 1 and parallel to the axis of rotation 6, so that the distance of the grinding wheel 3 to the lateral surface of the knife carrier drum 1 and the separating knife 2 arranged thereon is constant during the traversing movement and a collision of the grinding wheel 3 with the knife carrier drum 1 or the separating knives 2 both during the movement from the operating position into the conditioning chamber 8 and back into the operating position can be excluded.
- the abrasive body 3 as in the left embodiment of FIG. 3 shown, designed as a rotating grinding wheel, this can be aligned so that its axis of rotation 7 is also aligned parallel to the axis of rotation 6 of the knife carrier 1.
- the grinding wheel is moved in the direction of its axis of rotation 7 in the conditioning chamber 8, which constructive particularly easy to implement, for example by existing bearings or an existing shaft is used to achieve the sliding movement.
- thereby act during the sliding movement only very small inertial mass forces on the drive means, the bearing and the grinding wheel itself, since the disc is moved coaxially to its axis of rotation 7.
- the conditioning chamber 8 generally serves to change the properties of the grinding wheel 3, which are adversely affected by the operation and in particular by the wear, to such an extent that a high-quality grinding of the cutting blades 2 is possible even after a longer service life of the grinding wheel 3.
- These include, in particular, the cleaning and / or the dressing of the grinding body 3.
- a cleaning laser 10 is preferably provided in the conditioning chamber 8, which is directed onto the grinding surface of the grinding wheel 3.

Der Tabak wird der Tabakschneidevorrichtung in Form eines verdichteten, bedarfsweise mit Tabaksoße vermischten Tabakkuchens aus kurzen Tabakfasern zugeführt. Die Tabakschneidevorrichtung umfasst unter anderem eine angetriebene Messerträgertrommel, an deren Mantelfläche oder Stirnseite ein oder mehrere Trennmesser angeordnet sind, welche während der Bewegung der Messerträgertrommel periodisch an dem Mundstück des zugeführten Tabakkuchens vorbeigeführt werden und dabei die Tabakfasern in dünnen Streifen von dem Tabakkucken abtrennen.The tobacco is fed to the tobacco cutting device in the form of a compacted tobacco tobacco tobacco tobacco blended as needed with tobacco sauce. The tobacco cutting device comprises, inter alia, a driven knife carrier drum, on whose lateral surface or end face one or more cutting blades are arranged, which are periodically passed during the movement of the knife carrier drum on the mouthpiece of the tobacco cake supplied and thereby separating the tobacco fibers in thin strips of the tobacco pee.
Die Trennmesser der Tabakschneidevorrichtung unterliegen dabei einem nicht zu vermeidenden Verschleiß und einer nicht zu vermeidenden Verschmutzung während des Schnittvorganges durch den zugeführten Tabakkuchen. Ursächlich für den Verschleiß und die Verschmutzung der Trennmesser sind dabei im Wesentlichen harte Partikel in dem Tabakkuchen und die in dem Tabakkuchen vorhandene Tabaksoße bzw. der beim Schneiden des Tabakkuchens erzeugte Tabakstaub. Damit dieser Verschleiß bzw. diese Verschmutzung der Trennmesser die Schnittqualität nicht nachteilig beeinflusst, müssen die Trennmesser regelmäßig nachgeschliffen und nachgeführt werden. Zum Schleifen der Trennmesser sind entsprechende Einrichtungen mit einem Schleifkörper aus z.B. kubischem Bornitrit (CBN) oder Korund vorgesehen, welcher seinerseits während des Schleifvorganges der Trennmesser zwangsläufig verschlissen und/oder durch die Verschmutzung des Trennmessers verunreinigt wird. Damit dieser Verschleiß und/oder diese Verunreinigung des Schleifkörpers wiederum das Schleifen der Trennmesser nicht nachteilig beeinflusst, muss der Schleifkörper selbst in regelmäßigen Abständen abgerichtet und/oder gereinigt werden, wobei das Abrichten und Reinigen auch in einem einzigen Bearbeitungsvorgang des Schleifkörpers erfolgen kann. Zum Abrichten des Schleifkörpers wird die Schleiffläche des Schleifkörpers z.B. mittels eines Diamanten abgezogen oder mittels eines hochenergetischen Laserstrahls abgefahren bzw. bearbeitet. Ein solches Abrichten kann bei der Verwendung von Schleifkörpern aus kubischem Bornitrit entfallen, sofern der Verschleiß dieses Werkstoffes so gering ist, dass dieser die Schleifqualität nicht nennenswert verschlechtert. Das Reinigen des Schleifkörpers ist aufgrund der anhaftenden Tabaksoße und des anhaftenden Tabakstaubes jedoch unabhängig von dem Grundwerkstoff des Schleifkörpers für einen qualitativ hochwertigen Schleifvorgang der Trennmesser zur Erhaltung der Schnittqualität zwingend erforderlich.The cutting blades of the tobacco cutting device are subject to unavoidable wear and unavoidable contamination during the cutting process by the supplied tobacco cake. The reason for the wear and the contamination of the separating blades are essentially hard particles in the tobacco cake and the tobacco sauce present in the tobacco cake or the tobacco dust produced when cutting the tobacco cake. In order for this wear or contamination of the cutting knife does not adversely affect the quality of cut, the cutting blades must be regularly reground and tracked. For grinding the cutting blades are appropriate facilities with a grinding wheel from eg cubic boron nitride (CBN) or corundum provided, which in turn is inevitably worn during the grinding process of the cutting blade and / or contaminated by the contamination of the cutting blade. In order for this wear and / or contamination of the grinding wheel in turn does not adversely affect the grinding of the cutting blade, the abrasive body itself must be dressed and / or cleaned evenly at regular intervals, the dressing and cleaning can also be done in a single machining operation of the grinding wheel. To dress the grinding wheel, the grinding surface of the grinding wheel is pulled off, for example by means of a diamond, or cut or machined by means of a high-energy laser beam. Such dressing can be omitted when using cubic boron nitride abrasives, provided that the wear of this material is so low that it does not significantly deteriorate the grinding quality. Cleaning of the abrasive article, however, is imperative due to the adhering tobacco sauce and the adhering tobacco dust, regardless of the base material of the abrasive article, for a high quality grinding operation of the cutting blades to maintain the cut quality.
Aus der
Aufgabe der Erfindung ist es, eine Tabakschneidevorrichtung mit einer Einrichtung zum Schleifen eines Trennmessers der Tabakschneidevorrichtung zu schaffen, welche konstruktiv möglichst einfach aufgebaut sein soll, und bei der das Abrichten und/oder Reinigen des Schleifkörpers mit einer geringstmöglichen Verschmutzung des zu schneidenden Produktes und/oder Gefährdung der Umgebung bzw. der handhabenden Person möglich sein soll.The object of the invention is to provide a tobacco cutting device with a device for grinding a cutting knife of the tobacco cutting device, which should be structurally simple as possible, and in the dressing and / or cleaning of the abrasive body with the least possible contamination of the product to be cut and / or Endangerment of the environment or the person handling should be possible.
Zur Lösung der Aufgabe wird erfindungsgemäß eine Tabakschneidevorrichtung mit den Merkmalen des Anspruchs 1 vorgeschlagen, während weitere bevorzugte Weiterentwicklungen den Unteransprüchen zu entnehmen sind.To achieve the object, a tobacco cutting device according to the invention with the features of claim 1 is proposed, while further preferred developments are given in the dependent claims.
Gemäß dem Grundgedanken der Erfindung wird vorgeschlagen, dass die Konditionierkammer an einer der Stirnseiten der Messerträgertrommel angeordnet ist, und der Schleifkörper zum Abrichten und/oder Reinigen in einer parallel zu der Rotationsachse der Messerträgertrommel gerichteten Verfahrbewegung aus einer Betriebsposition in die Konditionierkammer verfahrbar ist.According to the basic idea of the invention, it is proposed that the conditioning chamber is arranged on one of the front sides of the knife carrier drum, and the grinding body can be moved from an operating position into the conditioning chamber for dressing and / or cleaning in a traversing movement directed parallel to the axis of rotation of the knife carrier drum.
Der Vorteil der vorgeschlagenen Lösung ist darin zu sehen, dass der Produktbereich, in dem die Tabakfasern von dem Tabakkuchen abgeschnitten werden, durch die vorgeschlagene Anordnung der Konditionierkammer und die Verfahrbewegung des Schleifkörpers räumlich eindeutig von dem Bereich getrennt ist, in dem der Schleifkörper gereinigt und/oder abgerichtet wird. Dadurch kann die Wahrscheinlichkeit einer Verschmutzung des Produktes erheblich verringert werden. Ferner kann die Konditionierkammer, da sie nicht mehr an dem Umfang der Messerträgertrommel angeordnet ist und dadurch nicht mehr konstruktiv an die Betriebsposition des Schleifkörpers bzw. an die Geometrie der Messerträgertrommel angepasst werden muss, hinsichtlich der Dichtigkeit und einer erhöhten Sicherheit erheblich einfacher ausgelegt werden. Insgesamt kann der Schleifvorgang durch die vorgeschlagene Anordnung der Konditionierkammer wesentlich günstiger und sicherer hinsichtlich der vorgegebenen Anforderungen verwirklicht werden. Dabei ist es für einen einfachen konstruktiven Aufbau der Tabakschneidevorrichtung und das Auffinden der Betriebsposition des Schleifkörpers nach dem Abrichten und/oder Reinigen besonders günstig, dass der Schleifkörper parallel zu der Rotationsachse der Messerträgertrommel in die Konditionierkammer verfahrbar ist, so dass die Position des Schleifkörpers während des Verfahrens allein in einer Achse verändert wird, und die Ausrichtung des Schleifkörpers in Richtung der beiden anderen Achsen nicht verändert wird. Ferner kann durch die vorgeschlagene Lösung ein und dieselbe Konditionierkammer zum Abrichten und/oder Reinigen von Schleifkörpern unterschiedlicher Tabakschneidevorrichtungen mit unterschiedlichen Messerträgertrommeln verwendet werden.The advantage of the proposed solution is the fact that the product area in which the tobacco fibers are cut from the tobacco cake, by the proposed arrangement of the conditioning chamber and the movement of the grinding wheel spatially clearly separated from the area in which the abrasive article is cleaned and / or dressed. This can significantly reduce the likelihood of contamination of the product. Furthermore, since the conditioning chamber no longer has to be arranged on the circumference of the knife carrier drum and therefore does not have to be adapted constructively to the operating position of the grinding wheel or to the geometry of the knife carrier drum, it can be made considerably simpler in terms of tightness and increased safety. Overall, the grinding process can be realized by the proposed arrangement of the conditioning significantly cheaper and safer in terms of the specified requirements. It is particularly favorable for a simple structural design of the tobacco cutting device and finding the operating position of the abrasive article after dressing and / or cleaning that the abrasive body is movable parallel to the axis of rotation of the knife carrier drum in the conditioning chamber, so that the position of the abrasive body during the Method alone is changed in one axis, and the orientation of the grinding wheel in the direction of the other two axes is not changed. Furthermore, by the proposed solution, one and the same conditioning chamber can be used for dressing and / or cleaning abrasive articles of different tobacco cutting devices with different knife carrier drums.
Weiter wird vorgeschlagen, dass an der Konditionierkammer eine Temperatursensoreinrichtung und/oder eine Zuführeinrichtung zur Zuführung eines Reinigungs- und/oder Löschmittels und/oder ein Reinigungslaser zum Reinigen des Schleifkörpers und/oder eine Absaugeinrichtung vorgesehen ist.It is further proposed that a temperature sensor device and / or a feed device for supplying a cleaning and / or extinguishing agent and / or a cleaning laser for cleaning the grinding wheel and / or a suction device is provided on the conditioning chamber.
Mittels der Temperatursensoreinrichtung kann insbesondere die Temperatur des Schleifkörpers z.B. während des Abrichtens gemessen werden, so dass das Abrichten unterbrochen oder verlangsamt wird, wenn eine vorgegebene Temperatur überschritten wird. Dadurch kann die Brandgefahr und die Gefahr einer Beschädigung der Bauteile durch eine Überhitzung verringert werden. Ferner können durch die bauliche Trennung der Konditionierkammer von der Messerträgertrommel vereinfacht eine Zuführeinrichtung für ein Reinigungs- oder Löschmittel und/oder ein Reinigungslaser und/oder eine Absaugeinrichtung an der Konditionierkammer vorgesehen werden. Ferner können neben den genannten besonders bevorzugten Einrichtungen auch weitere Einrichtungen zur Verbesserung des Abrichtens und/oder Schleifens des Schleifkörpers vorgesehen werden.By means of the temperature sensor device, in particular, the temperature of the abrasive body, e.g. during dressing, so that the dressing is interrupted or slowed down when a predetermined temperature is exceeded. As a result, the risk of fire and the risk of damage to the components can be reduced by overheating. Furthermore, the structural separation of the conditioning chamber from the knife carrier drum can simplify the supply of a cleaning or extinguishing agent and / or a cleaning laser and / or a suction device to the conditioning chamber. Furthermore, in addition to the above-mentioned particularly preferred devices, further devices for improving the dressing and / or grinding of the grinding body can be provided.
Weiter wird vorgeschlagen, dass die Konditionierkammer eine mittels einer Schließeinrichtung verschließbare Öffnung aufweist, durch welche der Schleifkörper in die Konditionierkammer einfahrbar ist. Die Öffnung ist dabei an der Seite der Konditionierkammer angeordnet, welche der Messerträgertrommel zugewandt ist, so dass der Schleifkörper in einer linearen, einachsialen Bewegung parallel zu der Richtung der Rotationsachse der Messerträgertrommel in die Konditionierkammer eingefahren werden kann.It is further proposed that the conditioning chamber has a closable by means of a closing device opening through which the grinding body is retractable into the conditioning chamber. The opening is arranged on the side of the conditioning chamber, which faces the knife carrier drum, so that the grinding body can be moved into the conditioning chamber in a linear, uniaxial movement parallel to the direction of the axis of rotation of the knife carrier drum.
Ferner kann die Konditionierkammer auch ein zweiteiliges Gehäuse mit einem ersten und einem zweiten Teil aufweisen, wobei das erste und das zweite Teil des Gehäuses in der Betriebsposition des Schleifkörpers voneinander getrennt sind, und wenigstens eines der Teile des Gehäuses eine durch die Bewegung des Schleifkörpers aus der Betriebsposition in die Konditionierkammer gesteuerte Bewegung ausführt, durch welche die beiden Teile des Gehäuses zur Anlage aneinander gelangen. Durch die vorgeschlagene Lösung wird die Konditionierkammer durch das Ergänzen der Teile des Gehäuses erst dann vollständig geschlossen, wenn der Schleifkörper aus der Betriebsposition herausgefahren wird. Dabei wird die Bewegung der Teile des Gehäuses bewusst durch die Bewegung des Schleifkörpers gesteuert, so dass die Bewegungen gekoppelt sind und das vollständige Schließen des Gehäuses erst dann erfolgt, wenn der Schleifkörper in einer bestimmten Position angeordnet oder in einen bestimmten räumlichen Abschnitt eingetreten ist.Further, the conditioning chamber may also comprise a two-part housing having a first and a second part, wherein the first and the second part of the housing are separated in the operating position of the grinding body, and at least one of the parts of the housing by the movement of the grinding body from the Operating position in the conditioning chamber controlled movement performs, through which the two parts of the housing come to rest against each other. By the proposed solution, the conditioning chamber is completed by the completion of the parts of the housing only fully closed when the grinding wheel is moved out of the operating position. In this case, the movement of the parts of the housing is deliberately controlled by the movement of the abrasive body, so that the movements are coupled and the complete closing of the housing takes place only when the grinding body has been arranged in a certain position or entered a certain spatial section.
Weiter wird vorgeschlagen, dass das erste Teil des Gehäuses ortsfest an der Tabakschneidevorrichtung angeordnet ist, und das zweite Teil des Gehäuses bewegungstechnisch mit dem Schleifkörper gekoppelt ist. Durch die vorgeschlagene Lösung kann der Bewegungsablauf besonders einfach verwirklicht werden, indem das erste Teil des Gehäuses feststehend ausgebildet ist und das zweite Teil zur Vervollständigung des Gehäuses auf das erste Teil des Gehäuses zu bewegt wird. Insbesondere kann das zweite Teil des Gehäuses auch fest mit einem Träger des Schleifkörpers ausgebildet sein, so dass das zweite Teil des Gehäuses zusammen mit dem Schleifkörper verfahren wird. Das zweite Teil bildet in diesem Fall praktisch eine Haube, welche zusammen mit dem Schleifkörper gegenüber der Messerträgertrommel verfahren wird.It is further proposed that the first part of the housing is fixedly arranged on the tobacco cutting device, and the second part of the housing is coupled in terms of movement with the grinding body. The proposed solution, the movement can be particularly easily realized by the first part of the housing is fixed and the second part to complete the housing is moved to the first part of the housing. In particular, the second part of the housing may also be fixedly formed with a carrier of the abrasive body, so that the second part of the housing is moved together with the grinding body. In this case, the second part practically forms a hood, which is moved together with the grinding body relative to the knife carrier drum.
Insbesondere kann das erste Teil des Gehäuses ortsfest an der Tabakschneidevorrichtung angeordnet sein und das zweite Teil des Gehäuses die Schließeinrichtung der Öffnung bilden. Der Schleifkörper kann dann durch die Öffnung in das erste Teil des Gehäuses eingefahren werden, welche dann während der weiteren Einfahrbewegung durch das fest mit dem Träger des Schleifkörpers verbundene zweite Teil des Gehäuses verschlossen wird.In particular, the first part of the housing may be fixedly arranged on the tobacco cutting device and the second part of the housing form the closing device of the opening. The grinding body can then be retracted through the opening in the first part of the housing, which is then closed during the further retraction by the second part of the housing fixedly connected to the carrier of the grinding body.
Weiter wird vorgeschlagen, dass der Schleifkörper mittels einer Antriebseinrichtung zum Schleifen des Trennmessers in verschiedenen Betriebspositionen zu einer parallel zu der Rotationsachse der Messerträgertrommel gerichteten Bewegung antreibbar ist, und der Schleifkörper mittels derselben Antriebseinrichtung zum Ausführen der Verfahrbewegung in die Konditionierkammer antreibbar ist. Eine solche Bewegung des Schleifkörpers in verschiedene Betriebspositionen kann z.B. dann vorgesehen sein, wenn die Breite des Schleifkörpers kleiner als die Breite der Trennmesser ist. In diesem Fall kann der Schleifkörper unmittelbar während des Schleifens bzw. während des Umlaufens der Messerträgertrommel kontinuierlich oder in Intervallen entlang der Rotationsachse der Messerträgertrommel bewegt werden, so dass das oder die Trennmesser an verschiedenen Stellen seiner Längsrichtung nachgeschliffen wird. Diese Antriebseinrichtung kann in diesem Fall aufgrund der vorgeschlagenen Richtung der Verfahrbewegung in die Konditionierkammer gleichzeitig auch zum Verfahren des Schleifkörpers in die Konditionierkammer genutzt werden.It is also proposed that the grinding body can be driven by means of a drive device for grinding the separating knife in different operating positions to a parallel to the axis of rotation of the knife carrier drum directed movement, and the grinding body by means of the same drive means for carrying out the movement into the conditioning chamber is drivable. Such movement of the abrasive article to various operating positions may be e.g. be provided when the width of the abrasive body is smaller than the width of the cutting blade. In this case, the grinding body can be moved continuously or at intervals along the axis of rotation of the knife carrier drum during grinding or during the rotation of the knife carrier drum, so that the separating knife or blades are reground at different points in its longitudinal direction. This drive device can be used in this case due to the proposed direction of the movement in the conditioning chamber at the same time also for moving the grinding body in the conditioning chamber.

Dazu zählen insbesondere das Reinigen und/oder das Abrichten des Schleifkörpers 3. Dazu sind in der Konditionierkammer 8 bevorzugt ein Reinigungslaser 10 vorgesehen, welcher auf die Schleifoberfläche des Schleifkörpers 3 gerichtet ist. Außerdem kann eine Zuführeinrichtung 14 zum Zuführen eines Reinigungs- und/oder Löschmittels und eine Absaugeinrichtung 12 zur Abführung des Reinigungs-und/oder Löschmittels und/oder der bei der Reinigung und/oder dem Abrichten freigesetzten Partikel vorgesehen sein. Ferner ist in der Konditionierkammer 8 ein die Position des Schleifkörpers 3 detektierender Positionssensor 11 vorgesehen, in Abhängigkeit von dessen Signal eine in der
Die Konditionierkammer 8 umfasst damit sämtliche Bauteile zum Konditionieren und insbesondere zum Reinigen und/oder Abrichten des Schleifkörpers 3 und kann unabhängig von der Geometrie der Messerträgertrommel 1 baugleich für unterschiedliche Tabakschneidevorrichtungen der gattungsgemäßen Art verwendet werden. Ferner kann die Konditionierkammer 8 aufgrund der abgeschlossenen Bauweise und der von der Messerträgertrommel 1 getrennten Anordnung erheblich einfacher gekapselt und ausgelegt werden, wobei insbesondere die Anordnung und Auslegung der Absaugeinrichtung 12, der Schließeinrichtung 15 und der Zuführeinrichtung 14 einschließlich der Anschluss an externe Baugruppen und Steuereinrichtungen einfacher gestaltet werden kann.The

Durch die vorgeschlagene Lösung kann ein Schleifen der Trennmesser 2 ermöglicht werden, ohne dass Schleifstaub in den Produktbereich gelangen kann. Ferner kann durch die Wahl eines besonders schonenden Reinigungsverfahrens, wie z.B. mittels des Reinigungslasers 10 eine besonders hohe Standzeit des Schleifkörpers 3 erzielt werden. Der konstruktive Aufbau und der Bewegungsablauf einschließlich der damit verbundenen Mechanik können besonders dadurch vereinfacht werden, indem der Schleifkörper 3 zur Bewegung aus der Betriebsposition in die Reinigungsposition eine lineare, einachsiale Bewegung parallel zu der Rotationsachse 6 und parallel zu der Mantelfläche der Messerträgertrommel 1 gerichtete Bewegung ausführt. Selbstverständlich können die Teile 18 und 19 der Konditionierkammer 8 auch einzeln über vorgesehene Gelenke schwenkbar ausgebildet sein, so dass ein Zugriff von außen zu dem Schleifkörper 3 ermöglicht wird. Dabei kann z.B. insbesondere das zusammen mit dem Schleifkörper 3 verfahrbare Teil 19 an der dem Teil 18 zugewandten Seite eine Klappe aufweisen, so dass der Schleifkörper 3 in der Betriebsstellung vollständig durch das Teil 19 gekapselt ist. Durch die Klappe kann dann eine Öffnung geschaffen werden, durch die der Schleifkörper 3 ausgefahren werden kann, oder welche dazu genutzt wird, dass das Teil 19 und das Teil 18 zusammen in der Reinigungsstellung des Schleifkörpers 3 die geschlossene Konditionierkammer 8 bilden. Dazu wird die Klappe verschwenkt und das Teil 19 mit der geöffneten Klappe an das Teil 18 herangefahren.By the proposed solution, a grinding of the cutting blade 2 can be made possible without grinding dust can get into the product area. Furthermore, a particularly long service life of the
