Definitions
- the present invention relates to a station for applying fluid media, in particular glue, to a substrate, such as a blank or a web of material for a cigarette packet.
- the invention further relates to a method for operating such a station.
- such a station comprises at least one valve group of redundant valves, each of which (automatically) can take over the function of another valve of the valve group if necessary.
- fluid medium in particular as a portion or in portions
- the station is designed so that each valve is automatically moved from a working position in which it can apply the fluid medium to the substrate in a non-working position (in which it can not).
- a second valve of the valve group in a working position movable, which then takes over the function of the first valve.
- the station has redundant, in particular similar valves, each - for example, during the cleaning of a valve of the valve group - in particular moved from its non-working position to the working position and then used instead of the valve to be cleaned, so that the station without Business interruption continue to work or can continue to operate.
- a first valve of the valve group is generally transferred from a working state to a non-working state
- a second valve of the valve group assumes the function of the first and automatically from a non-working state in which it no medium is applied to the substrate, transferred to a working state in which it then applies medium to the substrate.
- one or more valves it would thus also be possible for one or more valves to already be in their working position when the first valve is transferred to the non-operating state, but not yet working or not yet applying any medium to the substrate, ie not in a working condition.
- the second valve is moved from a non-working position to a working position when the first valve is transferred from the working state to the non-working state.
- substrate is understood to mean, moreover, any article (or any material) which can be acted upon by such a fluid medium, irrespective of whether it is present as a sheet-like material, as a blank or in another form.
- portions of the fluid medium are applied successively to many substrates at such a station.
- a station can be used for gluing a cyclically or continuously conveyed material web or blanks conveyed cyclically successively along the station.
- the control device of the station ensures that the substrate (for example by means of a suitable conveyor ) is moved relative to the second valve so that it can then act on the same location of the substrate with fluid medium, as would otherwise have done the first valve.
- the station or the valves in such a way that the discharge openings of the redundant valves point to one and the same spatial position in their respective working positions. For example, by being arranged at an angle to each other.
- valves of the group are arranged side by side.
- Each valve is individually from the respective non-working position in the respective working position (and back) movable, in particular pivotable.
- each valve of the group individually along a common axis of rotation of the valves from the respective non-working position in the respective working position (and back) is pivotable.
- each valve of the group can be automatically cleaned if necessary by a particular common or all valves of the group associated cleaning member.
- the non-working position can then be, for example, a cleaning position, into which each valve of the group, in particular the nozzle of the respective valve, can be moved individually and in which it can be cleaned with the cleaning member, in particular a rotatable cleaning roller.
- the non-working position can also be a flushing position (which differs in particular from the cleaning position) in which the respective valve of the group is flushed if necessary.
- the rinsing is preferably carried out after a cleaning of the valve by the cleaning member. In particular, before the valve is returned to the working state or the working position.
- the valve is flushed in the course of the flushing process with the fluid medium itself.
- the fluid medium itself.
- a rinsing with a solvent for the respective fluid medium in the simplest case, for example, water.
- the cleaning member can be transferred to a second position by means of a drive from a first position in which the respective valve, in particular the nozzle of the same, touches the cleaning member insofar as it is in a cleaning position, in which case this is not the case is (in which therefore no contact occurs in this constellation) and in which the respective valve without collision with the cleaning member from its working position or its cleaning position is movable into the flushing position.
- the cleaning member in its first position would block the movement of the valve from its working position to the flushing position while not doing so in its second position.
- each valve on a (own, only this assigned) movable Swivel arm is attached, which is pivotable about the common axis of rotation of all valves of the group.
- the plurality of pivot axes of the plurality of valves would be arranged side by side along the common axis of rotation or mounted on this and individually rotatable about this (between the valve positions described).
- each valve in particular the respective pivot arm to which the valve is optionally attached, assigned a drive, in particular its own (the other valves or pivot arms not assigned) controllable by a control device or controlled drive, with which the respective valve or swivel arm, from the respective working position in the non-working position (and back) is movable.
- a drive may for example be a compressed air cylinder.
- the orientation of the valves it is preferably provided that, in the event that all the valves of the group are in their working position, the discharge openings of the valves, in particular their nozzle openings, along a common unbent / straight line or a common non-curved plane are arranged.
- the valves are preferably arranged in a single row next to each other.
- the cleaning member in particular the cleaning roller, it is preferably arranged above a liquid detergent detergent tray.
- the detergent trough is then by means of a common drive together with the cleaning member of the respective valve blocking position in one or the position movable, in which the cleaning member does not block the movement of the valve from the working position or the cleaning position in the flushing position.
- the station has at least two groups of valves each redundant in the respective group, wherein the substrate is arranged between the two groups, so that with the valves of one group the fluid medium on a first substrate side and with the valves the other group, the fluid medium can be applied to a particular opposite second substrate side.
- the cleaning member is arranged between the valve groups, so that the valves of both groups can be cleaned with the cleaning member.
- At least two valves of the group are always in a working state in which they apply fluid medium to the substrate while at least one further valve of the group is in a non-working state.
- the station 10 shown by way of example in the figures serves for applying individual portions 11 of fluid medium, here glue, to a substrate 12, here on a shoulder of a so-called cap box for cigarettes.

Description
Die vorliegende Erfindung betrifft eine Station zum Aufbringen von fluiden Medien, insbesondere Leim, auf ein Substrat, wie etwa auf einen Zuschnitt oder eine Materialbahn für eine Zigarettenpackung. Die Erfindung betrifft des Weiteren ein Verfahren zum Betreiben einer solchen Station.The present invention relates to a station for applying fluid media, in particular glue, to a substrate, such as a blank or a web of material for a cigarette packet. The invention further relates to a method for operating such a station.
Stationen mit Leimventilen zum Aufbringen von Leim sind beispielsweise im Bereich der Zigarettenverpackungsindustrie gut bekannt. So etwa im Zusammenhang mit der Aufbringung von einzelnen Leimportionen auf Faltlappen von Zuschnitten für Zigarettenpackungen.Stations with glue-on glue delivery stations are well known, for example, in the cigarette packaging industry. For example, in connection with the application of individual glue portions on folding flaps of blanks for cigarette packs.
Insbesondere die Verwendung hochviskosen Leims führt dabei häufig zu Verschmutzungen von Leimventilen und infolge dessen zu Betriebsunterbrechungen. Erst nach einer Reinigung derselben kann mit dem Aufbringen des Leims fortgefahren werden.In particular, the use of high-viscosity glue often leads to contamination of glue valves and as a result to business interruptions. Only after a cleaning of the same can be continued with the application of the glue.
Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, die eingangs genannte Station sowie das eingangs genannte Verfahren zum Betreiben derselben weiterzuentwickeln.Proceeding from this, it is an object of the present invention to further develop the aforementioned station as well as the method mentioned above for operating the same.
Diese Aufgabe wird gelöst durch eine Station mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zum Betreiben derselben mit den Merkmalen des Anspruchs 12.This object is achieved by a station having the features of
Danach umfasst eine solche Station mindestens eine Ventilgruppe aus redundanten Ventilen, von denen jedes bei Bedarf (automatisch) die Funktion eines anderen Ventils der Ventilgruppe übernehmen kann. Mit jedem Ventil dieser Ventilgruppe ist fluides Medium (insbesondere als Portion bzw. portionsweise) jeweils gezielt auf das Substrat aufbringbar. Dabei ist die Station so ausgebildet, dass jedes Ventil jeweils automatisch von einer Arbeitsstellung, in der es das fluide Medium auf das Substrat aufbringen kann, in eine Nicht-Arbeitsstellung bewegbar ist (in der es dies nicht kann). Dabei ist für den Fall, dass ein erstes Ventil der Ventilgruppe in die Nicht-Arbeitsstellung bewegt wird, für dieses erste Ventil ein zweites Ventil der Ventilgruppe in eine Arbeitsstellung bewegbar, das dann die Funktion des ersten Ventils übernimmt.Thereafter, such a station comprises at least one valve group of redundant valves, each of which (automatically) can take over the function of another valve of the valve group if necessary. With each valve of this valve group, fluid medium (in particular as a portion or in portions) can be selectively applied to the substrate. In this case, the station is designed so that each valve is automatically moved from a working position in which it can apply the fluid medium to the substrate in a non-working position (in which it can not). In this case, in the event that a first valve of the valve group is moved to the non-working position, for this first valve, a second valve of the valve group in a working position movable, which then takes over the function of the first valve.
Mit anderen Worten weist die Station redundante, insbesondere gleichartige Ventile auf, die jeweils - beispielsweise während der Reinigung eines Ventils der Ventilgruppe - insbesondere aus ihrer Nicht-Arbeitsstellung in die Arbeitsstellung bewegt und dann anstelle des zu reinigenden Ventils verwendet werden können, sodass die Station ohne Betriebsunterbrechung weiter arbeiten bzw. weiter betrieben werden kann.In other words, the station has redundant, in particular similar valves, each - for example, during the cleaning of a valve of the valve group - in particular moved from its non-working position to the working position and then used instead of the valve to be cleaned, so that the station without Business interruption continue to work or can continue to operate.
Bei der Nicht-Arbeitsstellung der Ventile der Ventilgruppe handelt es sich jeweils regelmäßig um eine von der Arbeitsstellung beabstandete Position des Ventils, insbesondere eine Reinigungs- oder Spülstellung.In the non-working position of the valves of the valve group is in each case regularly spaced from the working position position of the valve, in particular a cleaning or flushing position.
Was das oben erwähnte Verfahren zum Betreiben einer solchen Station zum Aufbringen von fluiden Medien betrifft, so kann der erfindungsgemäße Gedanke noch allgemeiner gefasst werden. Für den Fall, dass ein erstes Ventil der Ventilgruppe ganz allgemein von einem Arbeitszustand in einen Nicht-Arbeitszustand überführt wird, ist danach vorgesehen, dass ein zweites Ventil der Ventilgruppe die Funktion des ersten übernimmt und hierfür automatisch von einem Nicht-Arbeitszustand, in dem es kein Medium auf das Substrat aufbringt, in einen Arbeitszustand überführt wird, in dem es dann Medium auf das Substrat aufbringt. Erfindungsgemäß wäre es somit auch möglich, dass sich ein oder mehrere Ventile zwar bereits in ihrer Arbeitsstellung befinden, wenn das erste Ventil in den Nicht-Arbeitszustand überführt wird, allerdings noch nicht arbeiten bzw. noch kein Medium auf das Substrat aufbringen, also sich nicht in einem Arbeitszustand befinden.As for the above-mentioned method of operating such a fluid-media-station, the idea of the present invention may be more broadly understood. In the event that a first valve of the valve group is generally transferred from a working state to a non-working state, it is then provided that a second valve of the valve group assumes the function of the first and automatically from a non-working state in which it no medium is applied to the substrate, transferred to a working state in which it then applies medium to the substrate. According to the invention, it would thus also be possible for one or more valves to already be in their working position when the first valve is transferred to the non-operating state, but not yet working or not yet applying any medium to the substrate, ie not in a working condition.
Regelmäßig wird es so sein, dass das zweite Ventil von einer Nicht-Arbeitsstellung in eine Arbeitsstellung bewegt wird, wenn das erste Ventil von dem Arbeitszustand in den Nicht-Arbeitszustand überführt wird.Periodically, it will be so that the second valve is moved from a non-working position to a working position when the first valve is transferred from the working state to the non-working state.
Unter "Substrat" wird im Rahmen der Erfindung im Übrigen jeder Gegenstand (bzw. jedes Material) verstanden, der mit einem solchen fluiden Medium beaufschlagt werden kann, unabhängig davon, ob er als bahnförmiges Material vorliegt, als Zuschnitt oder in sonstiger Form.In the context of the invention, "substrate" is understood to mean, moreover, any article (or any material) which can be acted upon by such a fluid medium, irrespective of whether it is present as a sheet-like material, as a blank or in another form.
In der Regel werden an einer solchen Station nacheinander auf viele Substrate Portionen des fluiden Mediums aufgetragen. Beispielsweise bei einer Zigarettenverpackungsmaschine kann eine solche Station für das Beleimen einer taktweise oder kontinuierlich geförderten Materialbahn oder von taktweise aufeinander folgend entlang der Station geförderten Zuschnitten verwendet werden.As a rule, portions of the fluid medium are applied successively to many substrates at such a station. For example, in a cigarette packaging machine, such a station can be used for gluing a cyclically or continuously conveyed material web or blanks conveyed cyclically successively along the station.
Was die Übernahme der Funktion des ersten Ventils durch das zweite Ventil betrifft, so wird erfindungsgemäß mit dem zweiten Ventil der Ventilgruppe auf das Substrat an der oder den Positionen flüssiges Medium aufgebracht, an denen das erste Ventil diese hätte aufbringen können, wenn es in seiner Arbeitsstellung verblieben wäre bzw. in seinem Arbeitszustand. Bevorzugt wird dies bei Ventilen, deren jeweilige Ausgabeöffnung auf unterschiedliche Raumpositionen zeigen, durch ein geeignetes Bewegen bzw. Positionieren des Substrats relativ zu den beiden Ventilen erreicht. Wenn beispielsweise das erste Ventil aus seiner Arbeitsstellung in die Nicht-Arbeitsstellung bewegt wird und das zweite Ventil anstelle dessen zum Aufbringen das fluiden Mediums eingesetzt wird, kann vorgesehen sein, dass die Steuereinrichtung der Station dafür sorgt, dass das Substrat (beispielsweise mittels eines geeigneten Förderers) soweit relativ zu dem zweiten Ventil bewegt wird, dass dieses anschließend dieselbe Stelle des Substrats mit fluidem Medium beaufschlagen kann, wie dies ansonsten das erste Ventil getan hätte. Theoretisch ist alternativ natürlich auch denkbar, die Station bzw. die Ventile so auszubilden, dass die Ausgabeöffnungen der redundanten Ventile in ihren jeweiligen Arbeitsstellungen auf ein und dieselbe Raumposition zeigen. Etwa, indem sie winklig zueinander angeordnet sind.As regards the assumption of the function of the first valve by the second valve, according to the invention with the second valve of the valve group is applied to the substrate at the one or more positions liquid medium, where the first valve could have applied this when it is in its working position would remain or in his working condition. This is preferably achieved in the case of valves whose respective dispensing openings point to different spatial positions by suitably moving or positioning the substrate relative to the two valves. For example, if the first valve is moved from its operative position to the non-operative position and the second valve is instead used to apply the fluid medium, it may be provided that the control device of the station ensures that the substrate (for example by means of a suitable conveyor ) is moved relative to the second valve so that it can then act on the same location of the substrate with fluid medium, as would otherwise have done the first valve. Theoretically, of course, it is also conceivable to design the station or the valves in such a way that the discharge openings of the redundant valves point to one and the same spatial position in their respective working positions. For example, by being arranged at an angle to each other.
Vorzugsweise sind die Ventile der Gruppe nebeneinander angeordnet. Jedes Ventil ist dabei einzeln von der jeweiligen Nicht-Arbeitsstellung in die jeweilige Arbeitsstellung (und zurück) bewegbar, insbesondere verschwenkbar.Preferably, the valves of the group are arranged side by side. Each valve is individually from the respective non-working position in the respective working position (and back) movable, in particular pivotable.
Dabei kann vorgesehen sein, dass jedes Ventil der Gruppe einzeln entlang einer gemeinsamen Drehachse der Ventile von der jeweiligen Nicht-Arbeitsstellung in die jeweilige Arbeitsstellung (und zurück) verschwenkbar ist.It can be provided that each valve of the group individually along a common axis of rotation of the valves from the respective non-working position in the respective working position (and back) is pivotable.
Vorzugsweise kann jedes Ventil der Gruppe bei Bedarf automatisch durch ein insbesondere gemeinsames bzw. allen Ventilen der Gruppe zugeordnetes Reinigungsorgan gereinigt werden.Preferably, each valve of the group can be automatically cleaned if necessary by a particular common or all valves of the group associated cleaning member.
Was die Nicht-Arbeitsstellung betrifft, so kann diese dann beispielsweise eine Reinigungsstellung sein, in die jedes Ventil der Gruppe, insbesondere die Düse des jeweiligen Ventils, jeweils einzeln bewegbar ist und in der es mit dem Reinigungsorgan, insbesondere einer rotierbaren Reinigungswalze, reinigbar ist.As far as the non-working position is concerned, it can then be, for example, a cleaning position, into which each valve of the group, in particular the nozzle of the respective valve, can be moved individually and in which it can be cleaned with the cleaning member, in particular a rotatable cleaning roller.
Die Nicht-Arbeitsststellung kann auch eine (sich insbesondere von der Reinigungsstellung unterscheidende) Spülstellung sein, in der das jeweilige Ventil der Gruppe bei Bedarf gespült wird. Das Spülen erfolgt bevorzugt nach einer Reinigung des Ventils durch das Reinigungsorgan. Insbesondere, bevor das Ventil wieder in den Arbeitszustand bzw. die Arbeitsstellung überführt wird.The non-working position can also be a flushing position (which differs in particular from the cleaning position) in which the respective valve of the group is flushed if necessary. The rinsing is preferably carried out after a cleaning of the valve by the cleaning member. In particular, before the valve is returned to the working state or the working position.
Vorzugsweise wird das Ventil im Rahmen des Spülvorgangs mit dem fluiden Medium selbst gespült. Theoretisch denkbar wäre aber auch ein Spülen mit einem Lösungsmittel für das jeweilige fluide Medium, im einfachsten Fall beispielsweise Wasser.Preferably, the valve is flushed in the course of the flushing process with the fluid medium itself. Theoretically conceivable would be a rinsing with a solvent for the respective fluid medium, in the simplest case, for example, water.
Was das Reinigungsorgan betrifft, so kann es mittels eines Antriebs von einer ersten Stellung, in der das jeweilige Ventil, insbesondere die Düse desselben, das Reinigungsorgan berührt, insofern es sich in einer Reinigungsstellung befindet, in eine zweite Stellung überführbar sein, in der dies nicht der Fall ist (in der also in dieser Konstellation keine Berührung erfolgt) und in der das jeweilige Ventil ohne Kollision mit dem Reinigungsorgan von seiner Arbeitsstellung oder seiner Reinigungsstellung in die Spülstellung bewegbar ist.As far as the cleaning member is concerned, it can be transferred to a second position by means of a drive from a first position in which the respective valve, in particular the nozzle of the same, touches the cleaning member insofar as it is in a cleaning position, in which case this is not the case is (in which therefore no contact occurs in this constellation) and in which the respective valve without collision with the cleaning member from its working position or its cleaning position is movable into the flushing position.
Mit anderen Worten würde das Reinigungsorgan in diesem Fall in seiner ersten Stellung die Bewegung des Ventils aus seiner Arbeitsstellung in die Spülstellung blockieren, während es dies in seiner zweiten Stellung nicht tut.In other words, in this case, the cleaning member in its first position would block the movement of the valve from its working position to the flushing position while not doing so in its second position.
Was die weitere Ausbildung der Ventile der Ventilgruppe betrifft, so kann vorgesehen sein, dass jedes Ventil an einem (eigenen, nur diesem zugeordneten) bewegbaren Schwenkarm befestigt ist, der um die gemeinsame Drehachse aller Ventile der Gruppe verschwenkbar ist. Mit anderen Worten wären die mehreren Schwenkachsen der mehreren Ventile nebeneinander entlang der gemeinsamen Drehachse angeordnet bzw. an dieser gelagert und jeweils einzeln um diese (zwischen den beschriebenen Ventilstellungen) drehbar.As regards the further design of the valves of the valve group, it can be provided that each valve on a (own, only this assigned) movable Swivel arm is attached, which is pivotable about the common axis of rotation of all valves of the group. In other words, the plurality of pivot axes of the plurality of valves would be arranged side by side along the common axis of rotation or mounted on this and individually rotatable about this (between the valve positions described).
Vorzugsweise ist jedem Ventil, insbesondere dem jeweiligen Schwenkarm, an dem das Ventil ggf. befestigt ist, ein Antrieb zugeordnet, insbesondere ein eigener (den anderen Ventilen bzw. Schwenkarmen nicht zugeordneter) von einer Steuereinrichtung steuerbarer bzw. gesteuerter Antrieb, mit dem das jeweilige Ventil bzw. Schwenkarm, von der jeweiligen Arbeitsstellung in die Nicht-Arbeitsstellung (und zurück) bewegbar ist. Ein solcher Antrieb kann beispielsweise ein Druckluftzylinder sein.Preferably, each valve, in particular the respective pivot arm to which the valve is optionally attached, assigned a drive, in particular its own (the other valves or pivot arms not assigned) controllable by a control device or controlled drive, with which the respective valve or swivel arm, from the respective working position in the non-working position (and back) is movable. Such a drive may for example be a compressed air cylinder.
Was die Ausrichtung der Ventile betrifft, so ist vorzugsweise vorgesehen, dass für den Fall, dass sich sämtliche Ventile der Gruppe jeweils in ihrer Arbeitsstellung befinden, die Ausgabeöffnungen der Ventile, insbesondere ihre Düsenöffnungen, entlang einer gemeinsamen ungekrümmten/geraden Linie oder einer gemeinsamen ungekrümmten Ebene angeordnet sind. Dabei sind die Ventile vorzugsweise einreihig nebeneinander angeordnet.As regards the orientation of the valves, it is preferably provided that, in the event that all the valves of the group are in their working position, the discharge openings of the valves, in particular their nozzle openings, along a common unbent / straight line or a common non-curved plane are arranged. The valves are preferably arranged in a single row next to each other.
Was das Reinigungsorgan betrifft, insbesondere die Reinigungswalze, so ist sie bevorzugt oberhalb einer ein flüssiges Reinigungsmittel aufweisenden Reinigungsmittelwanne angeordnet. Bevorzugt ist dann die Reinigungsmittelwanne mittels eines gemeinsamen Antriebs zusammen mit dem Reinigungsorgan von der das jeweilige Ventil blockierenden Stellung in eine bzw. die Stellung bewegbar, in der das Reinigungsorgan die Bewegung des Ventils aus der Arbeitsstellung bzw. der Reinigungsstellung in die Spülstellung nicht blockiert.As regards the cleaning member, in particular the cleaning roller, it is preferably arranged above a liquid detergent detergent tray. Preferably, the detergent trough is then by means of a common drive together with the cleaning member of the respective valve blocking position in one or the position movable, in which the cleaning member does not block the movement of the valve from the working position or the cleaning position in the flushing position.
Gemäß einer weiteren Konkretisierung der Erfindung weist die Station mindestens zwei Gruppen von in der jeweiligen Gruppe jeweils redundanten Ventilen auf, wobei das Substrat zwischen den beiden Gruppen angeordnet ist, sodass mit den Ventilen der einen Gruppe das fluide Medium auf eine erste Substratseite und mit den Ventilen der anderen Gruppe das fluide Medium auf eine insbesondere gegenüberliegende zweite Substratseite aufbringbar ist. Dabei ist das Reinigungsorgan zwischen den Ventilgruppen angeordnet ist, sodass die Ventile beider Gruppen mit dem Reinigungsorgan reinigbar sind.According to a further concretization of the invention, the station has at least two groups of valves each redundant in the respective group, wherein the substrate is arranged between the two groups, so that with the valves of one group the fluid medium on a first substrate side and with the valves the other group, the fluid medium can be applied to a particular opposite second substrate side. In this case, the cleaning member is arranged between the valve groups, so that the valves of both groups can be cleaned with the cleaning member.
Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung befinden sich während des Betriebs der Station immer mindestens zwei Ventile der Gruppe in einem Arbeitszustand, in dem sie fluides Medium auf das Substrat aufbringen, während sich mindestens ein weiteres Ventil der Gruppe in einem Nicht-Arbeitszustand befindet.According to another preferred embodiment of the invention, during operation of the station at least two valves of the group are always in a working state in which they apply fluid medium to the substrate while at least one further valve of the group is in a non-working state.

Die in den Figuren beispielhaft gezeigte Station 10 dient zum Aufbringen von einzelnen Portionen 11 von fluidem Medium, hier Leim, auf ein Substrat 12, hier auf eine Schulter einer sogenannten Kappenschachtel für Zigaretten. Eine solche Station kann Teil einer übergeordneten Maschine sein. Etwa Teil einer entsprechenden Verpackungsmaschine zur Verpackung von Zigaretten in Zigarettenschachteln (nicht gezeigt).The
Die Station 10 verfügt über zwei Gruppen 13a und 13b von einzelnen Ventilen 14.1-14.6. Dies sind in diesem Beispiel Leimventile zum Aufbringen des Leims auf das Substrat 12. Die Ventile 14.1-14.3 gehören dabei zu der Ventilgruppe 13a, die Ventile 14.4-14.6 zu der Gruppe 13b.The
Mit den Ventilen 14.1-14.6 der Gruppen 13a, 13b können die Mediumportionen 11 - wie in den Figuren erkennbar ist - auf zwei gegenüberliegende Seiten des Substrats 12 aufgebracht werden. Jeweils zwei Ventile aus beiden Gruppen 13a, 13b sind zu den beiden Seiten des Substrats 12 in derselben Vertikalebene angeordnet und bilden jeweils ein Paar 14.1, 14.4 bzw. 14.2, 14.5 bzw. 14.3, 14.6.With the valves 14.1-14.6 of the
Es versteht sich, dass das erfindungsgemäße Konzept auch Ventile zum Aufbringen anderer fluider Medien umfasst bzw. entsprechende Stationen mit anderem Verwendungszweck.It is understood that the inventive concept also includes valves for applying other fluid media or corresponding stations with a different purpose.
Jedes Ventil 14.1-14.6 ist jeweils an einem (nur) diesem zugeordneten Schwenkarm 15 befestigt. Jeder Schwenkarm 15 ist drehbar gelagert. Die Schwenkarme 15 der Ventile 14.1-14.3 der Gruppe 13a sind dabei an einer gemeinsamen Drehachse 16a schwenkbar gelagert, die Schwenkarme 15 der Gruppe 13b an einer gemeinsamen Drehachse 16b. Die beiden Drehachsen 16a, 16b verlaufen parallel zueinander.Each valve 14.1-14.6 is in each case attached to a (only) this associated
Jedem Ventil 14.1-14-6 bzw. jedem Schwenkarm 15 ist jeweils ein eigener Antrieb 17 zugeordnet, mit dem der jeweilige Schwenkarm 15 bzw. das jeweilige Ventil 14.1-14. 3 bzw. 14.4-14.6 um die gemeinsame Drehachse 16a bzw. 16b verschwenkt werden kann. Im vorliegenden Fall handelt es sich bei den Antrieben 17 um Druckluftzylinder, deren Kolbenstangen 18 zur Bewegung der Schwenkarme 15 an diesen angelenkt sind. Naturgemäß könnten auch andere Antriebe, wie etwa Elektromotoren, Hydraulikzylinder etc. verwendet werden.Each valve 14.1-14-6 or each
Unterhalb des Substrats 12 bzw. zwischen der Ventilgruppe 13a und der Ventilgruppe 13b ist eine Reinigungseinrichtung 23 angeordnet, mit der die einzelnen Ventile 14.1-14.6 gereinigt werden können. Die Reinigungseinrichtung 23 umfasst ein oberes, im Reinigungsbetrieb rotierendes Reinigungsorgan 24, im vorliegenden Fall eine Reinigungswalze, sowie ein unteres, gegenläufig zur der Reinigungswalze rotierendes Transportorgan 25, vorliegend eine Transportwalze.Below the
Das untere Transportorgan 25 taucht in ein Reservoir von Reinigungsmedium 19 ein und transportiert das Reinigungsmedium 19 zu dem oberen Reinigungsorgan 24. Das Reinigungsmedium 19 befindet sich zu diesem Zweck in einer nach oben offenen Reinigungsmittelwanne 20 der Reinigungseinrichtung 23.The
Zu jeweils gegenüberliegenden Seiten der Reinigungsmittelwanne 20 sind jeweils nach oben offene Spülwannen 21 a und 21 b angeordnet.To each opposite sides of the
Die Reinigungseinrichtung 23 ist mittels einer Verfahreinheit 26 in Pfeilrichtung (
Die Ventile 14.1-14.6 können jeweils aus einer Arbeitsstellung 1, vgl.
Jedes Ventil 14.1-14.6 kann zudem in eine Spülstellung bewegt werden, vgl. Bezugsziffer 3, in der das jeweilige Ventil 14.1-14.6 (insbesondere nach einem Reinigungsvorgang) (durch-))gespült wird und Medium- bzw. Leimreste 22 in dem Ventil 14.1-14.6 in die jeweilige Wanne 21a, 21b gespült werden. Zu diesem Zweck wird in der Spülstellung durch das jeweilige Ventil 14.1-14.6 eine gewisse Menge des flüssigen Medium- bzw. des Leims geführt und in die jeweilige Wanne 21 a, 21 b geleitet.Each valve 14.1-14.6 can also be moved into a flushing position, cf.
Zwischen den einzelnen Positionen 1, 2 und 3 können die Ventile 14.1-14.6 bedarfsweise unter Verwendung der Antriebe 17 durch Verschwenken des jeweiligen Schwenkarms 15 hin- und her bewegt werden.Between the
Wie zu erkennen ist, sind die Ventile 14.1-14.6 so ausgebildet, dass für den Fall, dass sich sämtliche Ventile 14.1-14.6 der Gruppen 13a bzw. 13b jeweils in ihrer Arbeitsstellung 1 befinden, die Ausgabeöffnungen der Ventile 14.1-14.6, insbesondere ihre Düsenöffnungen, entlang einer gemeinsamen ungekrümmten/geraden Linie oder einer gemeinsamen ungekrümmten Ebene angeordnet sind (einreihige Anordnung).As can be seen, the valves 14.1-14.6 are designed so that in the event that all valves are 14.1-14.6 of the
Die einzelnen Bewegungen der einzelnen bewegbaren Organe und Bauteile der Station 10 werden im Betrieb derselben durch eine nichtdargestellte Steuerungseinrichtung der Station 10 (die auch Teil der übergeordneten Maschine sein kann) vorgegeben.The individual movements of the individual movable members and components of the
Besonders wichtig ist nun, dass die Ventile 14.1-14.6 jeder Gruppe 13a, 13b redundant ausgebildet sind. Mit anderen Worten können die Leimventile 14.1-14.3 der Gruppe 13a wechselweise die Funktion des jeweils anderen Ventils 14.1-14.3 derselben Gruppe 13a übernehmen. Gleiches gilt für die Ventile 14.4-14.6 der Gruppe 13b.It is particularly important now that the valves 14.1-14.6 of each
Dies, sowie der allgemeine Aufbau der Station 10 erlauben verschiedene vorteilhafte Verfahren zum Betreiben der Station 10.This, as well as the general construction of the
Die Zusammenhänge werden im Folgenden anhand der Ventilgruppe 13a erläutert. Sie gelten aber mutatis mutandis auch für die Ventilgruppe 13b.The relationships are explained below with reference to the
Beispielsweise kann jedes Ventil 14.1-14.3 der Gruppe 13b, wenn es gereinigt werden soll oder muss, jeweils automatisch während des Betriebs der Station 10 von der Arbeitsstellung 1, in der es das fluide Medium auf das Substrat aufbringen kann, in die Reinigungsstellung 2 oder die Spülstellung 2 bewegt werden, also in eine Nicht-Arbeitsstellung, in der das jeweilige Ventil 14.1-14.3 kein Medium aufbringen kann.For example, each valve 14.1-14.3 of the
Nur in der Arbeitsstellung 1 kann sich das jeweilige Ventil 14.1-14.3 in einem Arbeitszustand befinden, nämlich in einem Zustand, in dem es im Betrieb der Station 10 das fluide Medium auf das Substrat 12 aufbringen kann.Only in the working
Wenn eines der Ventile 14.1-14.3, etwa das Ventil 14.1 der Ventilgruppe 13a, aus der Arbeitsstellung 1 in die Spülstellung bewegt wird, ist vorgesehen, dass für dieses erste Ventil 14.1 eines der anderen Ventile, nämlich eines der Ventile 14.2, 14.3 der Ventilgruppe 13a, in seine entsprechende Arbeitsstellung 1 bewegt wird und dann anstelle des Ventils 14.1 die Mediumportionen 11 auf das Substrat 12 aufbringt. Die Station 10 kann hierdurch ohne Betriebsunterbrechung weiter arbeiten bzw. weiter betrieben werden.If one of the valves 14.1-14.3, for example the valve 14.1 of the
Um zu erreichen, dass die Mediumportionen 11 von dem Ventil 14.2 oder 14.3 an denselben Stellen auf das Substrat 12 aufgebracht werden, an denen das erste Ventil 14.1 diese aufgebracht hätte, wenn es in seiner Arbeitsstellung 1 verblieben wäre bzw. weiter ohne Reinigungs- oder Spülpause weiterbetrieben worden wäre, kann die Steuerung automatisch durch ein geeignetes Bewegen bzw. Positionieren des Substrats 12 dessen Relativlage zu dem Ventil 14.2 oder 14.3 anpassen.In order to achieve that the
Die Steuerung kann zu diesem Zweck beispielsweise dafür sorgen, dass das Substrat 12 mittels eines geeigneten (nicht gezeigten) Förderers soweit relativ zu dem zweiten Ventil 14.2 oder 14.3 bewegt wird, dass dieses anschließend dieselbe Stelle des Substrats 12 mit fluidem Medium beaufschlagt, wie dies ansonsten das Ventil 14.1 getan hätte.For this purpose, the control can, for example, ensure that the
Sollte vorgesehen sein, das Substrat 12 nicht im Stillstand mit dem Medium zu beaufschlagen, sondern während dieses an den Ventilen 14.1-14.3 (mittels eines Förderers) vorbeibewegt wird, ist auch denkbar, die Fördergeschwindigkeit zu diesem Zweck kurzfristig zu ändern und/oder die Zeitpunkte des Aufbringens der Mediumportionen 11 durch die Ventile 14.2 oder 14.3 jeweils geeignet anzupassen.If it should be provided that the
Die Reinigungseinrichtung 23 kann mittels der Verfahreinheit 26 in zwei besondere Stellungen verfahren werden. Nämlich eine (obere) Reinigungsstellung, in der die Ventile 14.1-14.3 das Reinigungsorgan 24 berühren und in der die Ventile 14.1-14.3 durch Rotation des Reinigungsorgans 24 gereinigt werden können. Zum anderen eine (untere) Wartungsstellung. In der Wartungsstellung kann die Reinigungseinrichtung 23 aufgrund besserer Zugänglichkeit in einfacher Weise gewartet werden. Zudem ermöglicht die Wartungsstellung, dass die Ventile 14.1-14.3 in ihre Spülstellung bewegt und in dieser gespült werden können.The
Denn in der Wartungsstellung der Reinigungseinrichtung 23 kollidieren die Ventile 14.1-14.3 nicht mit dem Reinigungsorgan 24 bzw. sie berühren dieses nicht, wenn die Ventile 14.1-14.3 zwischen ihren Stellungen 1, 2 und 3 hin- und her bewegt werden. Mit anderen Worten würde das Reinigungsorgan 24 der Reinigungseinrichtung 23 in deren (oberen) Reinigungsstellung die Bewegung der Ventile 14.1-14.3 aus ihrer jeweiligen Arbeitsstellung 1 oder aus ihrer jeweiligen Reinigungsstellung 2 in ihre Spülstellung 3 blockieren, während dies in der Wartungsstellung der Reinigungseinrichtung 23 nicht der Fall ist.For in the maintenance position of the
Falls ein in der Arbeitsstellung 1 oder der Spülstellung 3 befindliches Ventil 14.1-14.3 gereinigt werden soll, wird die Reinigungseinrichtung 23 - falls sie sich noch nicht in der Reinigungsstellung, sondern in der Wartungsstellung befindet -, in ihre Reinigungsstellung überführt bzw. bewegt, das Ventil 14.1-14.3 in seine Reinigungsstellung verfahren und anschließend das Ventil durch Rotation des Reinigungsorgans 24 gereinigt.If a located in the working
Falls ein in der Arbeitsstellung 1 oder der Reinigungsstellung 2 befindliches Ventil 14.1-14.3 gespült werden soll, wird die Reinigungseinrichtung 23 - falls sie sich noch nicht in der Wartungsstellung befindet -, in ihre Wartungsstellung bewegt, anschließend das Ventil 14.1-14.3 in seine Spülstellung 3 verfahren und schließlich gespült.If a located in the working
Es ist denkbar vorzusehen, dass sich im Betrieb die einzelnen Ventile 14.1-14.3 der Gruppe 13a zeitlich nacheinander gemäß einer festgelegten Reihenfolge im Arbeitszustand befinden, um etwaigen Verschleiß der Ventile 14.1-14.3 gleichmäßig auf alle Ventile 14.1-14.3 zu verteilen. Beispielsweise könnte sich zunächst nur das erste Ventil 14.1 in einem Arbeitszustand befinden. Wenn dieses dann gereinigt werden muss, wird es in den Nicht-Arbeitszustand überführt. Dessen Funktion übernimmt dann das Ventil 14.2. Wenn zu einem späteren Zeitpunkt das Ventil 14.2 gereinigt werden muss, wird das Ventil 14.3 anstelle dessen in den Arbeitszustand verbracht usw. Das (zwischenzeitlich gereinigte) Ventil 14.1 würde erst wieder in den Arbeitszustand überführt werden, wenn das Ventil 14.3 gereinigt werden muss.It is conceivable to provide that in operation the individual valves 14.1-14.3 of the
Die Station 10 kann im Übrigen zur Erhöhung der Leistungsfähigkeit auch so betrieben werden, dass sich während des Betriebs immer mindestens zwei Ventile 14.1-14.3 bzw. 14.4-14.6 der Gruppe 13a bzw. 13b in ihrer jeweiligen Arbeitsstellung 1 befinden und fluides Medium auf das Substrat 12 aufbringen, während sich (nur) mindestens ein weiteres Ventil 14.1-14.3 bzw. 14.4-14.6 der Gruppe 13a bzw. 13b in der Reinigungsstellung 2 oder der Spülstellung 3 befindet und die Funktion eines der beiden Ventile 14.1-14.3 bzw. 14.4-14.6 übernimmt, sobald eines der beiden gereinigt werden muss. Die Zusammenhänge können auch anhand der
Grundsätzlich ist auch denkbar, dass alle Ventile der Gruppen 13a, 13b im Betrieb, falls dies beispielsweise aufgrund besonders hoher Taktraten erforderlich wäre, gleichzeitig arbeiten bzw. sich gleichzeitig in ihrem Arbeitszustand befinden.In principle, it is also conceivable that all valves of the
Wie der Fachmann erkennt, sind viele verschiedene Ausführungsformen der Erfindung denkbar, ohne das grundlegende Konzept derselben zu verlassen.As those skilled in the art will recognize, many different embodiments of the invention are conceivable without departing from the basic concept thereof.
