- the product is transferred from the receptacle of the drum of the transferring transport device by canceling the negative pressure in this recording and by a negative pressure in the recording of the drum of the receiving transport device.
- the recordings are each provided with at least one hole, which are fluidically connected to a compressed air system.
- the holes in the receptacles for cleaning or for removing the products at other points of the circumference can be pressurized with compressed air.
- the arrangement of the locations on the circumference of the drums on which the products are taken over, transferred or removed or the holes are blown out for cleaning, are different for each transport device.
- the transport device has to a complex compressed air system, which is realized by bores and chambers in a fixed first bearing flange and a control ring, wherein the first bearing flange is used in addition to the storage of the rotating drum and for fastening the transport device to a module plate in the machine.
- the transport device is provided with an electric motor which is supported with its housing on a second bearing flange, which is centered in a bore of the module plate.
- the second bearing flange serves to support the motor shaft of the electric motor driving the drum. For the best possible running behavior of the driven drum, this should be centered both with respect to the driving motor shaft and with respect to the first bearing flange, but this can be structurally significant due to the use of two bearing flanges for centering the motor shaft and the drum.
- the vacuum chambers for generating the negative pressure in the bores, which open into the receptacles are arranged at least partially between the bearing flanges, so that the bearing flanges themselves and the adjacent parts additionally subject to increased demands in terms of manufacturing accuracy, so that the compressed air system after assembly of the transport device is correspondingly tight. Due to the complex individually designed individually for each transport device compressed air system and the structurally demanding storage or centering of the driven drum of the manufacturing process of the entire transport device is expensive and requires a very high manufacturing accuracy.
- the object of the invention is to provide a generic transport device, which is inexpensive to manufacture.

- the proposed valve chamber has the advantage that the compressed air can be supplied uniformly and via an opening into the valve chamber compressed air bore, which has a different orientation than the compressed air supplying the compressed air bore, can be individually forwarded. Thereby, a uniform connection pattern of the connection openings on the machine can be realized with a uniform supply of compressed air into the valve chamber, wherein the forwarding of the compressed air then takes place via the differently oriented compressed air bore regardless of the orientation of the supplying compressed air bore.
- the valve chamber in this case has the function of a distribution chamber, which allows for a uniformly arranged compressed air bore for supplying the compressed air, a forwarding of the compressed air to a independent of the supply of compressed air delivery location.

- vacuum chambers are provided, which are bounded by radially inner and outer walls of the bearing flange.
- the vacuum chambers are thereby realized regardless of the manufacturing accuracies by radially inner and outer walls already in the bearing flange and sealingly limited in the radial direction, and only have to be connected by the assembly of the transport device to the module plate to the compressed air system of the machine.
- the number of sealing surfaces to be joined together only during assembly of the transport device can thereby be substantially reduced.
- the vacuum chambers are arranged radially on the outside of the valve chamber.
- the bearing flange has a bearing surface on which the driven drum is mounted, and has a contact surface on which the control ring is centered.
- the proposed use of the bearing flange both for the storage of the drum and for centering the control ring has the advantage that the drum can be arranged with a very high positional accuracy and in particular particularly centric to the control ring, since the tolerance chain between the drum and the control ring over that in the prior art known solution is substantially reduced.
- the driven drum is drivable via a drive shaft of the drive means, and the bearing flange has a bearing surface for the driven drum and a bearing surface for the drive shaft.
- the centering of the drum to the drive shaft can be carried out very accurately, since the tolerance chain can be shortened compared to the solution known in the prior art.
- the accuracy of the centering thus depends solely on the relative position of the bearing surface to the centering surface on the bearing flange and the accuracy of the bearing surface on the drum or the centering surface on the control ring.
- the bearing flange has a contact surface on which the drive device is centered with a housing.

- the bearing flange can for this purpose have a contoured bearing surface created by the compressed-air bores and / or by the vacuum chambers or their walls, against which the drive device is supported. Due to the proposed contoured contact surface, formed by the compressed air holes and / or the vacuum chambers or their walls, the transport device can be made very compact, the drive device and the compressed air system thereby complemented space-optimized.
- the drive device and the bearing flange overlap axially at least in sections. Due to the proposed axial overlap, the overall length of the transport device can be shortened, wherein the axial overlap relate to the housing and the parts of the drive means for generating the drive torque and not on the guided out of the drive means drive shaft.
- the inventively improved bearing flange both an increased degree of standardization of the transport device with an associated increase in the number of identical parts of the transport devices in the machine allows and significantly simplifies the structural design of the transport device by the storage and centering of the components on the bearing flange the Tolerance chains are reduced. Furthermore, the assembly of the transport device in the machine now takes place exclusively via the bearing flange which can be fastened to the module plate with a uniform connection pattern, so that the assembly itself is simplified and the error probability is reduced by incorrect assembly.

Unter stabförmigen Produkten der Tabak verarbeitenden Industrie werden im Allgemeinen z.B. Zigaretten, Zigarillos oder deren Filter verstanden, welche durch ein Hüllmaterial umfasst sind. Die Produkte werden in der Maschine in einem automatischen Herstellungsprozess hergestellt, wobei das Hüllmaterial in Form von einer Bahn zugeführt wird, in die Hüllmaterial, z.B. Tabak oder Filtermaterial, eingelegt wird, und die Hüllbahn anschließend zur Bildung eines stabförmigen Stranges verklebt wird. Die stabförmigen Produkte werden anschließend in einer vorbestimmten Länge von dem Strang abgeschnitten und weiter verarbeitet. Zum Transport der stabförmigen Produkte sind eine Mehrzahl von Transportvorrichtungen mit angetriebenen rotierenden Trommeln vorgesehen, welche an ihren äußeren Umfängen eine Vielzahl von Ausnehmungen aufweisen, in denen die Produkte während des Transportes mittels eines Unterdrucks gehalten werden. Zur Übergabe eines Produktes von einer Transportvorrichtung zu einer folgenden Transportvorrichtung wird das Produkt aus der Aufnahme der Trommel der übergebenden Transportvorrichtung durch Aufhebung des Unterdrucks in dieser Aufnahme und durch einen Unterdruck in der Aufnahme der Trommel der übernehmenden Transportvorrichtung übergeben. Die Aufnahmen sind dazu jeweils mit wenigstens einer Bohrung versehen, welche strömungstechnisch mit einem Druckluftsystem verbunden sind. Ferner können die Bohrungen in den Aufnahmen zur Reinigung oder zur Entnahme der Produkte an anderen Stellen des Umfanges mit Druckluft beaufschlagt werden. Die Anordnung der Stellen an dem Umfang der Trommeln, an denen die Produkte übernommen, übergeben oder entnommen bzw. die Bohrungen zum Reinigen ausgeblasen werden, sind dabei bei jeder Transportvorrichtung verschieden. Die Transportvorrichtung weist dazu ein aufwendiges Druckluftsystem auf, welches durch Bohrungen und Kammern in einem feststehenden ersten Lagerflansch und einem Steuerring verwirklicht ist, wobei der erste Lagerflansch zusätzlich zur Lagerung der sich drehenden Trommel und zur Befestigung der Transportvorrichtung an einer Modulplatte in der Maschine dient. Ferner ist die Transportvorrichtung mit einem Elektromotor versehen, welcher sich mit seinem Gehäuse auf einem zweiten Lagerflansch abstützt, der in einer Bohrung der Modulplatte zentriert ist. Zusätzlich dient der zweite Lagerflansch zur Lagerung der die Trommel antreibenden Motorwelle des Elektromotors. Für ein möglichst gutes Laufverhalten der angetriebenen Trommel sollte diese sowohl gegenüber der antreibenden Motorwelle als auch gegenüber dem ersten Lagerflansch zentriert sein, was aber aufgrund der Verwendung von zwei Lagerflanschen zur Zentrierung der Motorwelle und der Trommel konstruktiv erhebliche Schwierigkeiten bereiten kann.Under rod-shaped products of the tobacco processing industry are generally understood as cigarettes, cigarillos or their filters, which are covered by a shell material. The products are produced in the machine in an automatic manufacturing process, wherein the wrapping material is supplied in the form of a web, in the wrapping material, such as tobacco or filter material, is inserted, and the wrapping web is then bonded to form a rod-shaped strand. The rod-shaped products are then cut off in a predetermined length of the strand and further processed. For transporting the rod-shaped products, a plurality of transport devices with driven rotating drums are provided, which have at their outer peripheries a plurality of recesses in which the products are held during transport by means of a negative pressure. To transfer a product from a transport device to a subsequent transport device, the product is transferred from the receptacle of the drum of the transferring transport device by canceling the negative pressure in this recording and by a negative pressure in the recording of the drum of the receiving transport device. The recordings are each provided with at least one hole, which are fluidically connected to a compressed air system. Furthermore, the holes in the receptacles for cleaning or for removing the products at other points of the circumference can be pressurized with compressed air. The arrangement of the locations on the circumference of the drums on which the products are taken over, transferred or removed or the holes are blown out for cleaning, are different for each transport device. The transport device has to a complex compressed air system, which is realized by bores and chambers in a fixed first bearing flange and a control ring, wherein the first bearing flange is used in addition to the storage of the rotating drum and for fastening the transport device to a module plate in the machine. Further, the transport device is provided with an electric motor which is supported with its housing on a second bearing flange, which is centered in a bore of the module plate. In addition, the second bearing flange serves to support the motor shaft of the electric motor driving the drum. For the best possible running behavior of the driven drum, this should be centered both with respect to the driving motor shaft and with respect to the first bearing flange, but this can be structurally significant due to the use of two bearing flanges for centering the motor shaft and the drum.
Die Vakuumkammern zur Erzeugung des Unterdrucks in den Bohrungen, welche in die Aufnahmen münden, sind dabei zumindest abschnittsweise zwischen den Lagerflanschen angeordnet, so dass die Lagerflansche selbst sowie die angrenzenden Teile zusätzlich erhöhten Anforderungen hinsichtlich der Fertigungsgenauigkeiten unterliegen, damit das Druckluftsystem nach dem Zusammenbau der Transportvorrichtung entsprechend dicht ist. Aufgrund des aufwendig individuell für jede Transportvorrichtung unterschiedlich gestalteten Druckluftsystems und der konstruktiv anspruchsvollen Lagerung bzw. Zentrierung der angetriebenen Trommel ist der Herstellungsprozess der gesamten Transportvorrichtung teuer und bedarf einer sehr hohen Fertigungsgenauigkeit.The vacuum chambers for generating the negative pressure in the bores, which open into the receptacles are arranged at least partially between the bearing flanges, so that the bearing flanges themselves and the adjacent parts additionally subject to increased demands in terms of manufacturing accuracy, so that the compressed air system after assembly of the transport device is correspondingly tight. Due to the complex individually designed individually for each transport device compressed air system and the structurally demanding storage or centering of the driven drum of the manufacturing process of the entire transport device is expensive and requires a very high manufacturing accuracy.
Aufgabe der Erfindung ist es, eine gattungsgemäße Transportvorrichtung zu schaffen, welche kostengünstig herzustellen ist.The object of the invention is to provide a generic transport device, which is inexpensive to manufacture.
Die Aufgabe wird erfindungsgemäß durch eine Transportvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Weitere bevorzugte Ausführungsformen der Erfindung sind den Unteransprüchen, den Figuren und der zugehörigen Beschreibung zu entnehmen.The object is achieved by a transport device with the features of
Der Grundgedanke der Erfindung ist darin zu sehen, dass in der Transportvorrichtung ein Lagerflansch vorgesehen ist, welcher wenigstens zwei Druckluftbohrungen gleicher Funktion aufweist, und die Bohrungen in den Aufnahmen über eine der Druckluftbohrungen mit Druckluft beaufschlagbar sind, während die jeweils andere Druckluftbohrung gleicher Funktion als Blindleitung ausgebildet ist. Die Druckluftbohrung, welche als Blindleitung ausgebildet ist, kann z.B. durch einen Verschlussstopfen verschlossen sein, sofern diese auch mit einer Druckluft beaufschlagt wird. Alternativ kann die als Blindleitung ausgebildete Druckluftbohrung auch gar nicht erst an das Druckluftsystem angeschlossen werden, so dass sie auch nicht verschlossen werden muss. Wichtig ist nur, dass die Bohrungen in den Aufnahmen über die als Blindleitung ausgebildete Druckluftbohrung nicht mit Druckluft beaufschlagt werden, und die Druckluftbohrung demnach wirkungslos ist. Der Vorteil der vorgeschlagenen Lösung ist darin zu sehen, dass eine identische Transportvorrichtung dadurch für zwei oder mehrere unterschiedliche Anordnungen in der Maschine verwendet werden kann, wobei dann je nach der individuellen Anordnung der Transportvorrichtung die Bohrungen in den Aufnahmen über unterschiedliche Druckluftbohrungen an unterschiedlichen Stellen des Umfanges der Trommel mit Druckluft beaufschlagt werden. Dadurch können mit ein und derselben Transportvorrichtung unterschiedliche Übergabe- und Übernahmepunkte der Produkte, individuelle Entnahmestellen oder Positionen zum Reinigen der Bohrungen an dem Umfang der Transportvorrichtung mit einem sehr geringen konstruktiven Aufwand verwirklicht werden. Aufgrund dieser an unterschiedlichen Orten der Maschine verwendbaren Transportvorrichtung kann die Anzahl der herzustellenden Gleichteile der Transportvorrichtungen vergrößert werden, wodurch die Herstellungskosten der Transportvorrichtungen und die Instandsetzungskosten bei Schäden an der Maschine durch verminderte Lagervorhaltung verringert werden können. Ferner kann die Transportvorrichtung über ein einheitliches Anschraubbild und eine einheitliche Anordnung der Öffnungen der Druckluftbohrungen an der Modulplatte befestigt werden, wobei die Individualisierung der Transportvorrichtung für den jeweiligen Verwendungsort an der Maschine hinsichtlich der Übergabe- und Übernahmepunkte, der Entnahmestellen der Produkte und der Reinigungsstellen an dem Umfang der Trommel der Transportvorrichtung durch die individuelle Druckluftzuführung über die Druckluftbohrungen zu den Bohrungen in den Aufnahmen der Trommel in den Transportvorrichtungen selbst erfolgt.The basic idea of the invention is to be seen in that in the transport device, a bearing flange is provided, which has at least two compressed-air holes of the same function, and the holes in the receptacles via one of the compressed air holes are acted upon with compressed air, while the respective other compressed air bore the same function as stub is trained. The compressed-air bore, which is designed as a stub line, can be closed, for example, by a sealing plug, as long as it is also supplied with compressed air. Alternatively, the compressed-air bore formed as a stub line can not even be connected to the compressed air system so that it does not have to be closed. It is only important that the holes in the shots on the trained as a stub line compressed air hole are not acted upon with compressed air, and the compressed air bore is therefore ineffective. The advantage of the proposed solution is to be seen in that an identical transport device can thereby be used for two or more different arrangements in the machine, then applied depending on the individual arrangement of the transport device, the holes in the recordings on different compressed air holes at different locations of the circumference of the drum with compressed air become. As a result, different transfer and transfer points of the products, individual removal points or positions for cleaning the holes on the circumference of the transport device can be realized with a very low design effort with one and the same transport device. Because of this transport device which can be used at different locations of the machine, the number of identical parts of the transport devices to be produced can be increased, whereby the manufacturing costs of the transport devices and the repair costs for damage to the machine can be reduced by reduced stock retention. Furthermore, the transport device can be attached to the module plate via a uniform screw-on pattern and a uniform arrangement of the openings of the compressed-air bores, the individualization of the transport device for the respective place of use on the machine with regard to the transfer and transfer points, the removal points of the products and the cleaning points on the machine Scope of the drum of the transport device through the individual compressed air supply via the compressed air holes to the holes in the receptacles of the drum in the transport devices themselves.
Weiter wird vorgeschlagen, dass die Druckluftbohrungen gleicher Funktion diametral an dem Lagerflansch angeordnet sind. Durch die vorgeschlagene Anordnung der Anschlussöffnungen kann ein in Bezug auf die Anschlussöffnungen symmetrisches Anschlussbild verwirklicht werden, und die Anschlussöffnungen können sowohl in dem Lagerflansch als auch in der Modulplatte besonders positionsgenau gefertigt werden.It is further proposed that the compressed air holes of the same function are arranged diametrically on the bearing flange. Due to the proposed arrangement of the connection openings can be a symmetrical with respect to the connection openings connection diagram be realized, and the connection openings can be made particularly accurate position both in the bearing flange and in the module plate.
Eine weitere bevorzugte Ausführungsform der Erfindung kann dadurch verwirklicht sein, indem in dem Lagerflansch eine Ventilkammer vorgesehen ist, welche über wenigstens eine Druckluftbohrung mit Druckluft beaufschlagbar und über wenigstens eine Druckluftbohrung mit den Bohrungen in den Aufnahmen strömungstechnisch verbindbar ist. Die vorgeschlagene Ventilkammer weist den Vorteil auf, dass die Druckluft einheitlich zugeführt werden kann und über eine in die Ventilkammer mündende Druckluftbohrung, welche eine andere Ausrichtung als die die Druckluft zuführende Druckluftbohrung aufweist, individuell weitergeleitet werden kann. Dadurch kann ein einheitliches Anschlussbild der Anschlussöffnungen an der Maschine mit einer einheitlichen Zuführung der Druckluft in die Ventilkammer verwirklicht werden, wobei die Weiterleitung der Druckluft dann über die anders ausgerichtete Druckluftbohrung unabhängig von der Ausrichtung der zuführenden Druckluftbohrung erfolgt. Die Ventilkammer hat in diesem Fall die Funktion einer Verteilkammer, welche bei einer einheitlich angeordneten Druckluftbohrung zur Zuführung der Druckluft eine Weiterleitung der Druckluft zu einem von der Zuführung der Druckluft unabhängigen Abgabeort ermöglicht.A further preferred embodiment of the invention can be realized by a valve chamber is provided in the bearing flange, which is acted upon via at least one compressed air bore with compressed air and fluidly connected via at least one compressed air bore with the holes in the receptacles. The proposed valve chamber has the advantage that the compressed air can be supplied uniformly and via an opening into the valve chamber compressed air bore, which has a different orientation than the compressed air supplying the compressed air bore, can be individually forwarded. Thereby, a uniform connection pattern of the connection openings on the machine can be realized with a uniform supply of compressed air into the valve chamber, wherein the forwarding of the compressed air then takes place via the differently oriented compressed air bore regardless of the orientation of the supplying compressed air bore. The valve chamber in this case has the function of a distribution chamber, which allows for a uniformly arranged compressed air bore for supplying the compressed air, a forwarding of the compressed air to a independent of the supply of compressed air delivery location.
In diesem Fall wird weiter vorgeschlagen, dass die Ventilkammer wenigstens teilringförmig ausgebildet ist, und wenigstens zwei strömungstechnisch mit den Bohrungen in den Aufnahmen verbindbare Druckluftbohrungen vorgesehen sind, welche zueinander und/oder zu der Druckluftbohrung, über die die ventilkammer mit Druckluft beaufschlagbar ist, winkelversetzt in die Ventilkammer münden. Durch die wenigstens teilringförmige Ventilkammer und die winkelversetzten Druckluftbohrungen ist ein besonders einfacher konstruktiver Aufbau des Druckluftsystems ermöglicht, um die Druckluft von einer einheitlichen Druckluftbohrung zu verschiedenen Umfangsstellen der Transportvorrichtung zu führen. Die Ventilkammer kann dabei als Torus mit einer beliebigen Querschnittsfläche oder auch als Teilring über einen Teilkreisabschnitt ausgebildet sein, wichtig ist nur, dass durch die Ventilkammer eine zu der Zuströmung winkelversetzte Abströmung der Druckluft ermöglicht wird.In this case, it is further proposed that the valve chamber is formed at least partially annular, and at least two fluidly connectable with the holes in the receptacles compressed air holes are provided, which to each other and / or to the compressed air bore through which the valve chamber is acted upon with compressed air, angularly offset in the valve chamber open. Due to the at least partially annular valve chamber and the angular offset compressed air holes is a particularly simple structural design of the compressed air system allows to guide the compressed air from a single compressed air bore to different circumferential locations of the transport device. The valve chamber can be formed as a torus with any cross-sectional area or as a partial ring over a pitch circle section, it is only important that through the valve chamber to the inflow angular displacement of the compressed air is made possible.
Ferner wird vorgeschlagen, dass in dem Lagerflansch Vakuumkammern vorgesehen sind, welche durch radial innere und äußere Wandungen des Lagerflansches begrenzt sind. Die Vakuumkammern sind dadurch unabhängig von den Fertigungsgenauigkeiten durch radial innere und äußere Wandungen bereits in dem Lagerflansch verwirklicht und in Radialrichtung dichtend begrenzt, und müssen nur noch durch die Montage der Transportvorrichtung an der Modulplatte an das Druckluftsystem der Maschine angeschlossen werden. Die Anzahl der erst bei dem Zusammenbau der Transportvorrichtung zusammenzufügenden Dichtflächen kann dadurch wesentlich reduziert werden.It is also proposed that in the bearing flange vacuum chambers are provided, which are bounded by radially inner and outer walls of the bearing flange. The vacuum chambers are thereby realized regardless of the manufacturing accuracies by radially inner and outer walls already in the bearing flange and sealingly limited in the radial direction, and only have to be connected by the assembly of the transport device to the module plate to the compressed air system of the machine. The number of sealing surfaces to be joined together only during assembly of the transport device can thereby be substantially reduced.
Weiterhin wird vorgeschlagen, dass die Vakuumkammern radial außen an der Ventilkammer angeordnet sind. Durch die vorgeschlagene Anordnung der Vakuumkammern und der Ventilkammer kann ein kompakter Aufbau des Lagerflansches erzielt werden, wobei die Formgebung der Vakuumkammern und der Ventilkammern bauraumoptimiert aneinander angepasst sein können.Furthermore, it is proposed that the vacuum chambers are arranged radially on the outside of the valve chamber. The proposed arrangement of the vacuum chambers and the valve chamber, a compact construction of the bearing flange can be achieved, wherein the shape of the vacuum chambers and the valve chambers can be adapted to each other space-optimized.
Ferner wird vorgeschlagen, dass der Lagerflansch eine Lagerfläche aufweist, auf der die angetriebene Trommel gelagert ist, und eine Anlagefläche aufweist, an der der Steuerring zentriert ist. Die vorgeschlagene Nutzung des Lagerflansches sowohl zur Lagerung der Trommel als auch zur Zentrierung des Steuerringes weist den Vorteil auf, dass die Trommel mit einer sehr hohen Positionsgenauigkeit und insbesondere besonders zentrisch zu dem Steuerring angeordnet werden kann, da die Toleranzkette zwischen der Trommel und dem Steuerring gegenüber der im Stand der Technik bekannten Lösung wesentlich reduziert ist. Durch diese vorgeschlagene Zentrierung des Steuerringes und die Lagerung der Trommel kann die Transportvorrichtung unabhängig von dem weiterentwickelten Druckluftsystem konstruktiv weiter vereinfacht werden, wobei die Laufgenauigkeit der Trommel zu dem Steuerring während der Rotation dadurch zusätzlich verbessert werden kann.It is also proposed that the bearing flange has a bearing surface on which the driven drum is mounted, and has a contact surface on which the control ring is centered. The proposed use of the bearing flange both for the storage of the drum and for centering the control ring has the advantage that the drum can be arranged with a very high positional accuracy and in particular particularly centric to the control ring, since the tolerance chain between the drum and the control ring over that in the prior art known solution is substantially reduced. Through this proposed centering of the control ring and the storage of the drum, the transport device can be further simplified structurally independent of the advanced compressed air system, wherein the running accuracy of the drum to the control ring during rotation thereby can be further improved.
Außerdem wird vorgeschlagen, dass die angetriebene Trommel über eine Antriebswelle der Antriebseinrichtung antreibbar ist, und der Lagerflansch eine Lagerfläche für die angetriebene Trommel und eine Lagerfläche für die Antriebswelle aufweist. Durch die Lagerung der Antriebswelle und der Trommel auf ein und demselben Lagerflansch kann die Zentrierung der Trommel zu der Antriebswelle sehr genau ausgeführt werden, da die Toleranzkette im Vergleich zu der im Stand der Technik bekannten Lösung verkürzt werden kann. Die Genauigkeit der Zentrierung hängt damit ausschließlich von der relativen Lage der Lagerfläche zu der Zentrierfläche an dem Lagerflansch sowie von der Genauigkeit der Lagerfläche an der Trommel bzw. der Zentrierfläche an dem Steuerring ab.It is also proposed that the driven drum is drivable via a drive shaft of the drive means, and the bearing flange has a bearing surface for the driven drum and a bearing surface for the drive shaft. By supporting the drive shaft and the drum on one and the same bearing flange, the centering of the drum to the drive shaft can be carried out very accurately, since the tolerance chain can be shortened compared to the solution known in the prior art. The accuracy of the centering thus depends solely on the relative position of the bearing surface to the centering surface on the bearing flange and the accuracy of the bearing surface on the drum or the centering surface on the control ring.
Weiter wird vorgeschlagen, dass der Lagerflansch eine Anlagefläche aufweist, auf der die Antriebseinrichtung mit einem Gehäuse zentriert ist. Durch die vorgeschlagene Zentrierung der Antriebseinrichtung auf dem Lagerflansch ist eine feste Lagezuordnung der Antriebseinrichtung zu dem Lagerflansch geschaffen, welche unabhängig von externen Bauteilen und insbesondere unabhängig von der Montage der Transportvorrichtung an der Modulplatte ist.It is further proposed that the bearing flange has a contact surface on which the drive device is centered with a housing. The proposed centering of the drive means on the bearing flange a fixed position assignment of the drive means is provided to the bearing flange, which is independent of external components and in particular regardless of the mounting of the transport device to the module plate.
Ferner kann der Lagerflansch über mehrere Befestigungspunkte an der Modulplatte befestigt, und die Transportvorrichtung in einer durch die Lage der Befestigungspunkte und die Lage der Druckluftbohrungen vorbestimmten Ausrichtung an der Modulplatte befestigbar sein. Durch die Lage der Befestigungspunkte und die Lage der Druckluftbohrungen wird dadurch eine mechanische Codierung geschaffen, durch die eine Fehlmontage mit einer falschen Ausrichtung der Transportvorrichtung und insbesondere einer falschen Zuordnung der Druckluftbohrungen verhindert werden kann.Furthermore, the bearing flange can be fastened to the module plate via a plurality of attachment points, and the transport device can be fastened to the module plate in an orientation predetermined by the position of the attachment points and the position of the compressed-air bores. Due to the position of the attachment points and the position of the compressed-air bores, a mechanical coding is thereby created by which a faulty assembly with a wrong orientation of the transport device and in particular a wrong allocation of the compressed-air bores can be prevented.
Weiter wird vorgeschlagen, dass sich die Antriebseinrichtung der Transportvorrichtung mit einem Gehäuse drehfest an dem Lagerflansch abstützt. Durch die Abstützung der Antriebseinrichtung an dem Lagerflansch kann das bei dem Antrieb der Trommel erzeugte Reaktionsmoment über den Lagerflansch und dessen Befestigung in die Modulplatte der Maschine eingeleitet werden, so dass außer der Befestigung des Lagerflansches keinerlei weitere Verbindung der Transportvorrichtung zu der Maschine notwendig ist.It is further proposed that the drive device of the transport device with a housing rotatably supported on the bearing flange. By supporting the drive means on the bearing flange, the reaction torque generated in the drive of the drum can be introduced via the bearing flange and its attachment in the module plate of the machine, so that no further connection of the transport device to the machine is necessary except the attachment of the bearing flange.
Insbesondere kann der Lagerflansch dazu eine durch die Druckluftbohrungen und/oder durch die Vakuumkammern bzw. deren Wandungen geschaffene konturierte Anlagefläche aufweisen, an der sich die Antriebseinrichtung abstützt. Durch die vorgeschlagene konturierte Anlagefläche, gebildet durch die Druckluftbohrungen und/oder die vakuumkammern bzw. deren Wandungen, kann die Transportvorrichtung sehr kompakt ausgeführt werden, wobei die Antriebseinrichtung und das Druckluftsystem sich dabei bauraumoptimiert ergänzen.In particular, the bearing flange can for this purpose have a contoured bearing surface created by the compressed-air bores and / or by the vacuum chambers or their walls, against which the drive device is supported. Due to the proposed contoured contact surface, formed by the compressed air holes and / or the vacuum chambers or their walls, the transport device can be made very compact, the drive device and the compressed air system thereby complemented space-optimized.
Ferner wird vorgeschlagen, dass sich die Antriebseinrichtung und der Lagerflansch wenigstens abschnittsweise axial überlappen. Durch die vorgeschlagene axiale Überlappung kann die Baulänge der Transportvorrichtung verkürzt werden, wobei die axiale Überlappung sich auf das Gehäuse und die Teile der Antriebseinrichtung zur Erzeugung des Antriebsmomentes beziehen und nicht auf die aus der Antriebseinrichtung heraus geführte Antriebswelle.It is also proposed that the drive device and the bearing flange overlap axially at least in sections. Due to the proposed axial overlap, the overall length of the transport device can be shortened, wherein the axial overlap relate to the housing and the parts of the drive means for generating the drive torque and not on the guided out of the drive means drive shaft.
Durch den erfindungsgemäß verbesserten Lagerflansch wird sowohl ein erhöhter Standardisierungsgrad der Transportvorrichtung mit einer damit verbundenen Erhöhung der Anzahl der Gleichteile der Transportvorrichtungen in der Maschine ermöglicht als auch der konstruktive Aufbau der Transportvorrichtung wesentlich vereinfacht, indem durch die Lagerung und die Zentrierung der Bauteile auf dem Lagerflansch die Toleranzketten reduziert werden. Ferner erfolgt die Montage der Transportvorrichtung in der Maschine nunmehr ausschließlich über den an der Modulplatte befestigbaren Lagerflansch mit einem einheitlichen Anschlussbild, so dass die Montage an sich vereinfacht wird und die Fehlerwahrscheinlichkeit durch eine Fehlmontage reduziert wird. Der Lagerflansch stellt damit das zentrale Bauteil der Transportvorrichtung sowohl für die Zuführung der Druckluft als auch für die Lagerung und Zentrierung der Bauteile in der Transportvorrichtung und schließlich für die Montage der Transportvorrichtung und die Halterung der Antriebseinrichtung dar.The inventively improved bearing flange both an increased degree of standardization of the transport device with an associated increase in the number of identical parts of the transport devices in the machine allows and significantly simplifies the structural design of the transport device by the storage and centering of the components on the bearing flange the Tolerance chains are reduced. Furthermore, the assembly of the transport device in the machine now takes place exclusively via the bearing flange which can be fastened to the module plate with a uniform connection pattern, so that the assembly itself is simplified and the error probability is reduced by incorrect assembly. The bearing flange thus represents the central component of the transport device both for the supply of compressed air and for the storage and centering of the components in the transport device and finally for the assembly of the transport device and the holder of the drive device.

In der
An dem Lagerflansch 3 sind vier Befestigungsstellen 9, 10, 11 und 12 vorgesehen, über die die gesamte Transportvorrichtung 1 an einer Modulplatte 40, z.B. über Schrauben, befestigbar ist (siehe auch

Die gesamte Transportvorrichtung 1 ist demnach nur aus vier Grundelementen, nämlich der Antriebseinrichtung 4 mit der Antriebswelle 19, dem Lagerflansch 3, der Trommel 2 und dem Steuerring 23, zusammengesetzt. Der Steuerring 23 ist auf dem Lagerflansch 3 feststehend angeordnet und hat die Aufgabe, die Bohrungen 7 und 8 in den Aufnahmen 6 der sich um den Steuerring 23 drehenden Trommel 2 mit Druckluft mit unterschiedlichen Drücken oder mit Vakuum zu beaufschlagen, wodurch die Produkte 5 wahlweise in den Aufnahmen 6 gehalten oder aus diesen ausgeworfen werden oder die Bohrungen 7 und 8 an vorbestimmten Stellen des Umfangs der Transportvorrichtung 1 gereinigt werden.The
In dem Lagerflansch 3 sind ferner zwei Druckluftbohrungen 15 und 16 zu erkennen. Die Druckluftbohrung 15 mündet in eine torusförmige Ventilkammer 24 und wird zum Entnehmen der Produkte 5 aus den Aufnahmen 6 mit Druckluft beaufschlagt. Die Druckluftbohrung 16 dient zur Übergabe der Produkte 5 von der Transportvorrichtung 1 zu einer benachbart angeordneten nächsten Transportvorrichtung 1 und wird dazu permanent mit einem Überdruck von max. 10 mbar beaufschlagt. Der geringe Überdruck reicht insofern für die Übergabe der Produkte 5 aus, da die Produkte 5 gleichzeitig durch ein Vakuum in den Aufnahmen der Trommel der übernehmenden Transportvorrichtung angezogen werden.In the bearing
In dem Lagerflansch 3 sind zwei weitere diametral angeordnete Druckluftbohrungen 13 und 14 zu erkennen, welche zum Reinigen der Bohrungen 7 und 8 in den Aufnahmen 6 dienen und strömungstechnisch mit den Steuerring 23 durchdringenden Druckluftbohrungen 38 und 39 verbunden sind. Mindestens eine der Druckluftbohrungen 38 und 39 weist Austrittsöffnungen 49, 50, 51, 52 auf, welche in einem Bereich des Außenumfanges des Steuerringes 23 liegen, an dem die Bohrungen 7 und 8 der Aufnahmen 6 bei einer Rotation der Trommel 2 vorbei geführt werden. Bei einer Druckbeaufschlagung der.Druckluftbohrung 13 werden die Bohrungen 7 und 8 dann an einer durch die Lage der Austrittsöffnungen 49, 50, 51, 52 der Druckluftbohrung 38 festgelegten Stelle des Umfanges der Transportvorrichtung 1 frei geblasen.In the bearing
Die Druckluftbohrungen 13 und 14 haben damit dieselbe Funktion und werden z.B. je nach Drehsinn der Trommel 2, welcher von der Anordnung der Transportvorrichtung 1 in der Maschine abhängig ist, mit Druckluft beaufschlagt bzw. werden je nach dem Drehsinn der Trommel 2 verschlossen. Diejenige Druckluftbohrung 13 oder 14, welche nicht mit Druckluft beaufschlagt wird oder verschlossen ist, ist in diesem dargestellten Fall die erfindungsgemäße Blindleitung 14. Damit kann zumindest der Lagerflansch 3 mit einer identischen Formgebung für Transportvorrichtungen 1 unterschiedlicher Anordnung in der Maschine verwendet werden, an denen die Bohrungen 7 und 8 der Aufnahmen 6 an unterschiedlichen Stellen des Umfanges der Transportvorrichtung 1 zum Reinigen ausgeblasen werden.The
