Description

Die Erfindung betrifft einen Kanalplattenadapter gemäß dem Oberbegriff des Anspruches 1.The invention relates to a duct plate adapter according to the Preamble of claim 1.

Derartige beispielsweise in der DE 43 34 485 A1 beschriebene Kanalplattenadapter bestehen im wesentlichen aus einem vorzugsweise kreisförmig ausgebildeten Grundkörper mit einer rückseitigen, konisch ausgebildeten Anlagefläche sowie einem Mündungsteil, das während des Spinnbetriebes in den Spinnrotor ragt und dessen Abmessungen jeweils auf einen bestimmten Spinnrotordurchmesser bzw. einen Durchmesserbereich abgestimmt sind.
In dieses Mündungsteil des Kanalplattenadapters ist der Mündungsbereich eines sogenannten Faserleitkanales eingearbeitet. Außerdem ist eine zentrisch angeordnete Fadenabzugsdüse vorhanden.
Such channel plate adapters, described for example in DE 43 34 485 A1, essentially consist of a preferably circular base body with a rear, conical contact surface and an orifice part which projects into the spinning rotor during spinning operation and the dimensions of which are in each case a specific spinning rotor diameter or one Diameter range are matched.
The mouth area of a so-called fiber guide channel is incorporated into this mouth part of the channel plate adapter. There is also a centrally located thread take-off nozzle.

Das heißt, solche Kanalplatteriadapter weisen eine zentrale Durchgangsbohrung auf, in der eingangsseitig, auswechselbar, eine Fadenabzugsdüse festgelegt ist und in die ausgangsseitig ein sogenanntes Fadenabzugsröhrchen eingreift.That is, such channel plate adapters have a central one Through hole on, in the input side, exchangeable, a thread take-off nozzle is fixed and in the output side a so-called thread withdrawal tube engages.

Die in der zentralen Durchgangsbohrung auswechselbar festgelegte Fadenabzugsdüse besteht dabei in der Regel, wie beispielsweise in der DE 195 44 617 A1 dargestellt, aus einem speziellen Haltekörper und einer am Haltekörper unlösbar befestigten, keramischen Düsenmündung.
Der in der Regel ferromagnetische Haltekörper korrespondiert dabei mit entsprechenden in den Kanalplattenadapter eingelassenen Permanentmagnet einsätzen, die ihn kraftschlüssig fixierende
The thread take-off nozzle, which is interchangeably fixed in the central through-bore, generally consists, as shown for example in DE 195 44 617 A1, of a special holding body and a ceramic nozzle opening which is non-releasably attached to the holding body.
The generally ferromagnetic holding body corresponds to the corresponding permanent magnet inset in the channel plate adapter, which fixes it with a force fit

Diese seit langem bekannten Kanalplattenadapter haben sich in der Praxis an sich bewährt und ermöglichen es an Offenend-Spinnvorrichtungen optimale Spinnbedingungen zu schaffen.These long-known channel plate adapters have become proven in practice and make it possible on open-end spinning devices to create optimal spinning conditions.

Das heißt, wenn bei einem Partiewechsel beispielsweise die Spinnrotoren gegen kleinere Spinnrotoren getauscht werden, können auf relativ einfache Weise auch die Kanalplattenadapter gegen Kanalpiattenadapter mit angepaßtem Mündungsteil gewechselt werden.
Des weiteren kann bei einem solchen Partiewechsel durch entsprechende Wahl der leicht auswechselbar im Kanalplattenadapter angeordneten Fadenabzugsdüse auch das Spinnmaterial Berücksichtigung finden und zum Beispiel über die Falschdrallerteilung Einfluß auf die Fertigung des Fadens genommen werden.
This means that if, for example, the spinning rotors are exchanged for smaller spinning rotors during a batch change, the channel plate adapters can also be exchanged in a relatively simple manner for channel plate adapters with an adapted mouth part.
Furthermore, the spinning material can also be taken into account in such a batch change by appropriate selection of the thread take-off nozzle which is arranged in the channel plate adapter and can be exchanged, for example, by influencing the false twist to influence the manufacture of the thread.

Nachteilig bei diesen Kanalplattenadaptern ist allerdings ihre recht aufwendige Herstellung und damit verbunden ihr relativ hoher Preis.
Außerdem kann es in Ausnahmefällen, insbesondere bei schwierigen Garnen vorkommen, daß die magnetische Fixierung der Fadenabzugsdüse nicht ausreichend greift und die Fadenabzugsdüse in ihrer Aufnahmebohrung mitdrehen, was sich negativ auf den entstehenden Faden auswirkt.
A disadvantage of these duct plate adapters, however, is their rather complex manufacture and the relatively high price associated therewith.
In addition, it can happen in exceptional cases, especially with difficult yarns, that the magnetic fixation of the thread take-off nozzle does not grip sufficiently and the thread take-off nozzle rotates in its receiving bore, which has a negative effect on the thread being formed.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Kanalplattenadapter zu schaffen, der sowohl kostengünstig in der Fertigung als auch sicher in seiner Handhabung ist. Based on the aforementioned prior art, the Invention, the object of a channel plate adapter create the both inexpensive to manufacture as well is safe to use.

Diese Aufgabe wird erfindungsgemäß durch einen Kanalplattenadapter gelöst, wie er im Anspruch 1 beschrieben ist.This object is achieved by a Channel plate adapter solved, as described in claim 1 is.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are Subject of the subclaims.

Die erfindungsgemäße Ausbildung hat insbesondere den Vorteil, daß durch den Verzicht auf einen speziellen Haltekörper und das Festlegen der keramischen Düsenmündung direkt in der zentralen Durchgangsbohrung des Kanalplattenadapters die Fertigungskosten derartiger Kanalplattenadapter erheblich gesenkt werden.
Das heißt, die Kanalplattenadapter werden so günstig, daß es sinnvoll wird, unterschiedliche, komplett ausgestattete Kanalplattenadapter vorrätig zu halten und im Bedarfsfall einfach den kompletten Kanalplattenadapter zu wechseln.
Durch das Festlegen der keramischen Düsenmündung direkt in der zentralen Durchgangsbohrung ergibt nicht nur eine sehr sichere Verbindung, es können aizβerdem die Maße des in den Spinnrotor eintauchenden Mündungsteils des Kanalplattenadapters minimiert werden, was sich insbesondere bei Spinnrotoren mit kleinem Durchmesser positiv auswirkt beziehungsweise den Einsatz von Spinnrotoren mit einem Durchmesser deutlich unter 30 mm erst ermöglichte
The design according to the invention has the particular advantage that the manufacturing costs of such channel plate adapters are considerably reduced by dispensing with a special holding body and by fixing the ceramic nozzle mouth directly in the central through bore of the channel plate adapter.
This means that the duct plate adapters are so cheap that it makes sense to keep different, fully equipped duct plate adapters in stock and, if necessary, simply to change the complete duct plate adapter.
By fixing the ceramic nozzle orifice directly in the central through hole, not only does a very secure connection result, the dimensions of the orifice part of the channel plate adapter immersed in the spinning rotor can also be minimized, which has a positive effect in particular on spinning rotors with a small diameter or the use of spinning rotors with a diameter of significantly less than 30 mm

Wie im Anspruch 2 ausgeführt/ist dabei in bevorzugter Ausführungsform vorgesehen, daß die aus einem keramischen Werkstoff gefertigte Düsenmündung mittels Preßsitz direkt in einer eingangsseitig der zentralen Durchgangsbohrung angeordneten Aufnahmeöffnung unlösbar festgelegt ist. As stated in claim 2 / is more preferred Embodiment provided that the ceramic Material manufactured nozzle mouth by means of a press fit directly into one on the input side of the central through hole arranged receiving opening is fixed non-detachably.

Das Einpressen der keramischen Düsenmündung stellt dabei nicht nur ein sicheres und kostengünstiges Verbindungsverfahren dar, sondern ermöglicht außerdem eine einwandfreie Zentrierung der Düsenmündung, was sich positiv auf das abzuziehende Garn auswirkt.The pressing in of the ceramic nozzle orifice is not a problem just a safe and inexpensive connection method, but also enables perfect centering of the Nozzle mouth, which has a positive effect on the yarn to be drawn off effect.

In einer alternativen Ausführungsform kann allerdings auch vorgesehen sein, die Düsenmündung in der Aufnahmeöffnung der zentralen Durchgangsbohrung festzukleben (Anspruch 3).
Auch eine solche Klebeverbindung stellt ein sicheres, unlösbares Verbindungsverfahren dar, das kostengünstig durchzuführen ist.
In an alternative embodiment, however, provision can also be made to glue the nozzle mouth in the receiving opening of the central through hole (claim 3).
Such an adhesive connection also represents a safe, non-detachable connection method which can be carried out inexpensively.

Wie im Anspruch 4 dargelegt, ist in weiterer vorteilhafter Ausführungsform vorgesehen, daß im Bereich der zentralen Durchgangsbohrung, vorzugsweise im Anschluß an die Düsenmündung, eine den Faden abtastende Sensorik angeordnet ist.
Diese Sensorik, die beispielsweise als Thermosensor oder als Piezosensor ausgebildet sein kann, ist dabei beispielsweise geschützt zwischen der Düsenmündung und weiteren in der zentralen Durchgangsbohrung angeordneten Einrichtungen festgelegt und über eine Signalleitung an eine Steuereinrichtung der betreffenden Arbeitsstelle angeschlossen.
As stated in claim 4, it is provided in a further advantageous embodiment that a sensor sensing the thread is arranged in the area of the central through-bore, preferably following the nozzle mouth.
This sensor system, which can be designed, for example, as a thermal sensor or as a piezo sensor, is, for example, secured between the nozzle mouth and further devices arranged in the central through-hole and is connected via a signal line to a control device of the relevant work station.

In vorteilhafter Ausführungsform ist in der zentralen Durchgangsbohrung außerdem, wie im Anspruch 6 beschrieben, ein Verschleißschutz angeordnet.
Dieser Verschleißschutz ist aus einem hochverschleißfesten Material, beispielsweise aus einem keramischen Werkstoff, einem Hartmetall oder einem Werkstoff gefertigt, der plasmanitriert ist.
Durch den Einsatz eines solchen Verschleißschutzes kann die Lebensdauer des Kanalplattenadapters erheblich verlängert wird.
In an advantageous embodiment, wear protection is also arranged in the central through bore, as described in claim 6.
This wear protection is made from a highly wear-resistant material, for example from a ceramic material, a hard metal or a material that is plasma nitrided.
By using such wear protection, the service life of the duct plate adapter can be extended considerably.

Wie im Anspruch 7 beschrieben, kann in der zentralen Durchgangsbohrung anstelle eines Verschleißschutzes oder zusätzlich zum Verschleißschutz auch ein Wirbeleinsatz angeordnet sein.
Durch einen solchen Wirbeleinsatz, der den Faden mechanisch beaufschlagt, kann zusätzlicher Falschdrall auf den abzuziehenden Faden gegeben werden, was sich vorteilhaft auf die Spinnstabilität der Offenend-Spinnvorrichtung auswirkt.
As described in claim 7, instead of wear protection or in addition to wear protection, a swirl insert can also be arranged in the central through bore.
Such a swirl insert, which acts on the thread mechanically, can give additional false twist to the thread to be drawn off, which has an advantageous effect on the spinning stability of the open-end spinning device.

Aus dem gleichen Grunde kann anstelle eines mechanisch arbeitenden Wirbeleinsatzes auch eine Falschdrall-Blasdüseneinrichtung vorgesehen werden.
Auch durch eine solche, im Anspruch 8 beschriebene Falschdrall-Blasdüseneinrichtung kann die Spinnstabilität der Offenend-Spinnvorrichtung erhöht werden, wobei eine besonders schonende Fadenbehandlung gegeben ist, da keine zusätzliche mechanische Beanspruchung des abzuziehenden Fadens gegeben ist.
For the same reason, a false twist blowing nozzle device can also be provided instead of a mechanically working vortex insert.
The spinning stability of the open-end spinning device can also be increased by such a false twist blowing nozzle device, wherein a particularly gentle thread treatment is given, since there is no additional mechanical stress on the thread to be drawn off.

Die vorgenannten Einrichtungen sind von der Rückseite her in die zentrale Durchgangsbohrung des Kanalplattenadapters einführbar und dort auf einfache Weise durch einen lösbar angeordneten Arretierungseinsatz festlegbar (Anspruch 9). The above facilities are in from the back the central through hole of the duct plate adapter insertable and easily detachable there by a Arranged locking insert can be determined (claim 9).

Die jeweilige Ausstattung des Kanalplattenadapters kann dabei, wie im Anspruch 10 beschrieben, auf einfache Weise durch eine farbliche Kennzeichnung des Kanalplattenadapters sichtbar gemacht werden oder, wie im Anspruch 5 dargelegt, durch einen in der zentralen Durchgangsbohrung des Kanalplattenadapters festlegbaren Transponder.
Derartig gekennzeichnete Kanalplattenadapter sind eindeutig identifizierbar und können entsprechend den jeweiligen Erfordernissen problemlos eingesetzt bzw. ausgetauscht werden.
The respective equipment of the channel plate adapter can, as described in claim 10, be made visible in a simple manner by color coding the channel plate adapter or, as stated in claim 5, by a transponder which can be fixed in the central through-hole of the channel plate adapter.
Channel plate adapters marked in this way are clearly identifiable and can be used or exchanged without any problems according to the respective requirements.

Die Erfindung ist nachfolgend anhand der in den Zeichnungen dargestellten Ausführungsbeispiele näher erläutert.The invention is based on the in the drawings illustrated embodiments explained in more detail.

Die in Figur 1 dargestellte Offenend-Spinnvorrichtung 1 weist, wie bekannt, ein Rotorgehäuse 2 auf, in dem während des Spinnbetriebes ein Spinnrotor 3 mit hoher Drehzahl umläuft. Der Spinnrotor 3 ist dabei mit seinem Rotorschaft 22 in den Lagerzwickeln einer Stützscheibenlagerung 4 abgestützt und wird in axialer Richtung durch ein beispielsweise permanentmagnetisches Axiallager 21 fixiert.The open-end spinning device 1 shown in FIG. 1 has as known, a rotor housing 2, in which during the Spinning operation revolves around a spinning rotor 3 at high speed. The spinning rotor 3 is with its rotor shaft 22 in the Bearing gussets a support disc bearing 4 supported and is in the axial direction by a for example permanent magnetic axial bearing 21 fixed.

Der Antrieb des Spinnrotors 3 erfolgt dabei, wie üblich, über einen Tangentialnemen 5, der durch eine Stützrolle 44 an den Rotorschaft 22 angestellt wird.
Das an sich nach vorne offene Rotorgehäuse 2 ist über eine Saugleitung 6 an eine (nicht dargestellte) Unterdruckquelle angeschlossen und während des Spinnbetriebes nach vorne/durch eine sogenannte Faserkanalplatte 45 verschlossen.
Die Faserkanalplatte 45, die .an einem um eine Schwenkachse 16 begrenzt drehbar gelagerten Deckelelement 7 angeordnet ist, liegt dabei mit einem Lippendichtelement 17 an der Stirnseite des Rotorgehäuses 2 an.
The drive of the spinning rotor 3 takes place, as usual, via a tangential element 5 which is set against the rotor shaft 22 by a support roller 44.
The rotor housing 2, which is open at the front, is connected via a suction line 6 to a vacuum source (not shown) and is closed at the front during spinning operation / by a so-called fiber channel plate 45.
The fiber channel plate 45, which is arranged on a cover element 7 rotatably supported to a limited extent about a pivot axis 16, rests with a lip sealing element 17 on the end face of the rotor housing 2.

In das Deckelelement 7 ist außerdem eine Faserbandzuführ- und - auflöseeinrichtung 8 integriert, die unter anderem eine Faserbandauflösewalze 9, einen Faserbandeinzugszylinder 10 sowie einen Faserleitkanal 11 umfaßt.
Wie in Figur 1 dargestellt, wird die Faserbandauflösewalze 9 beispielsweise durch einen Tangentialriemen 12 angetrieben, während der Faserbandeinzugszylinder 10 über eine maschinenlange Antriebswelle oder, wie angedeutet, über einen Einzelantrieb 15, vorzugsweise einen Schrittmotor, beaufschlagt wird.
In addition, a sliver feeding and opening device 8 is integrated in the cover element 7, which includes, among other things, a sliver opening roller 9, a sliver feed cylinder 10 and a fiber guide channel 11.
As shown in Figure 1, the sliver roll 9 is driven, for example, by a tangential belt 12, while the sliver feed cylinder 10 is acted upon by a machine-long drive shaft or, as indicated, by a single drive 15, preferably a stepper motor.

In die Faserkanalplatte 45 ist eine in Richtung des Spinnrotors 3 hin offene Aufnahme 13 eingearbeitet, die eine kreisförmige, konisch ausgebildete Anlagefläche 24 aufweist. In dieser Aufnahme 13 ist, winkelgenau ausgerichtet, mit seinem Grundkörper 26 ein Kanalplattenadapter 18 leicht lösbar festgelegteIn the fiber channel plate 45 is one in the direction of Spinning rotor 3 incorporated open receptacle 13, the one has circular, conical bearing surface 24. In this receptacle 13 is aligned with an angle, with its base body 26 a channel plate adapter 18 easily detachable specified

Der Kanalplattenadapter 18, dessen verschiedene. Ausgestaltungsvarianten nachfolgend anhand der Figuren 2 bis 6 näher erläutert werden, verfügt.über eine zentrale Durchgangsbohrung 14. In der Durchgangsbohrung 14 ist eingangsseitig die aus einem keramischen Werkstoff gefertigte Düsenmündung 19 festgelegt. Ausgangsseitig greift ein sogenanntes Fadenabzugsröhrchen 20 in die zentrale Durchgangsbphrung 14.The channel plate adapter 18, its various. Design variants below with reference to FIGS. 2 to 6 has a central Through hole 14. In the through hole 14 is on the input side, the one made of a ceramic material Nozzle mouth 19 set. Intervenes on the output side so-called thread withdrawal tube 20 in the central Through hole 14.

Wie beispielsweise aus Figur 2 ersichtlich, ist die zentrale Durchgangsbohrung 14 des Kanalplattenadapters 18 eingangsseitig zu einer Aufnahmeöffnung 28 erweitert,deren Durchmesser geringfügig unter dem Durchmesser des Kopfteiles 27 der Düsenmündung 19 der Fadenabzugsdüse 23 liegt
Das heißt, die Düsenmündung 19 kann mit ihrem Kopfteil 27 in die Aufnahmeöffnurig 28 eingepreßt und dort mittels Preßsitz unlösbar festgelegt werden.
As can be seen, for example, from FIG. 2, the central through bore 14 of the channel plate adapter 18 is widened on the input side to a receiving opening 28, the diameter of which is slightly below the diameter of the head part 27 of the nozzle mouth 19 of the thread take-off nozzle 23
This means that the nozzle mouth 19 can be pressed with its head part 27 into the receiving opening 28 and fixed there in a non-detachable manner by means of a press fit.

In alternativer Ausführungsform kann der Durchmesser der Aufnahmeöffnung 28 allerdings auch geringfügig über dem Durchmesser des Kopfteiles 27 der Düsenmündung 19 liegen.
In diesem Fall wird die Düsenmündung 19 in den Kanalplattenadapter 18 eingeklebt.
Auch eine solche unlösbare Verbindung ist sehr sicher und einfach.
In an alternative embodiment, the diameter of the receiving opening 28 can, however, also be slightly above the diameter of the head part 27 of the nozzle mouth 19.
In this case, the nozzle mouth 19 is glued into the channel plate adapter 18.
Such an inseparable connection is also very secure and simple.

Wie aus Figur 2 weiter ersichtlich, ist innerhalb der zentralen Durchgangsbohrung 14, in Fadenlaufrichtung hinter der Düserimündung 19, des weiteren ein Verschleißschutz 31 angeordnet, der durch ein Arretierungselement 34, das beispielsweise aus einer Spannhülse 36 und einer Innensechskantschraube 35 besteht, auswechselbar fixiert ist. In bevorzugter Ausführungsform ist der Verschleißschutz 31 dabei aus einem keramischen Werkstoff, einem Hartmetall oder einem plasmanitrierten Werkstoff gefertigt.As can also be seen from FIG. 2, within the central through hole 14, behind in the thread running direction the nozzle orifice 19 and wear protection 31 arranged by a locking element 34, the for example from an adapter sleeve 36 and one Hexagon socket screw 35 is interchangeably fixed. In a preferred embodiment, wear protection is 31 thereby from a ceramic material, a hard metal or made of a plasma nitrided material.

Wie in Figur 3 angedeutet, kann anstelle eines Verschleißschutzes 31 oder zusätzlich zu einem solchen Verschleißschutzes 31 auch ein Wirbeleinsatz 32 in der zentralen Durchgangsbohrung 14 positioniert und durch ein Arretierungselement 34 fixiert werden.
Wie aus Figur 3 ersichtlich, kann auch das Arretierungselement 34 dabei etwas modifiziert sein.
Das heißt, anstelle einer Innensechskantschraube weist die zentrale Durchgangsbohrung 14 endseitig ein Gewinde zur Aufnahme eines speziellen Gewindeeinsatzes 37 auf.
Der mit einem Außengewinde ausgestattete Gewindeeinsatz 37 fixiert dann über die Spannhülse 36 den Wirbeleinsatz 32 beziehungsweise den Verschleißschütz 31.
As indicated in FIG. 3, instead of wear protection 31 or in addition to such wear protection 31, a swivel insert 32 can also be positioned in the central through bore 14 and fixed by a locking element 34.
As can be seen from FIG. 3, the locking element 34 can also be somewhat modified.
This means that instead of a hexagon socket screw, the central through bore 14 has a thread at the end for receiving a special thread insert 37.
The threaded insert 37, which is equipped with an external thread, then fixes the swivel insert 32 or the wear protector 31 via the clamping sleeve 36.

Die Figur 4 zeigt einen Kanalplattenadapter 18 mit einer im Bereich der zentralen Durchgangsbohrung 14 angeordneten Sensorik 29.
Diese den laufenden Faden abtastende Sensorik 29 ist beispielsweise als Thermosensor oder als Piezosensor ausgebildet und zum Beispiel über eine Signalleitung 38 an eine arbeitsstelleneigene Steuereinrichtung 43 angeschlossen. Die Sensorik 29 ermöglicht während des Spinnbetriebes eine zuverlässige Überwachung des über die Düsenmündung 19 abgezogenen Fadens.
FIG. 4 shows a channel plate adapter 18 with a sensor system 29 arranged in the area of the central through hole 14.
This sensor 29, which scans the running thread, is designed, for example, as a thermal sensor or as a piezo sensor and is connected, for example, via a signal line 38 to a control device 43 in the workplace. The sensor system 29 enables reliable monitoring of the thread drawn off via the nozzle mouth 19 during the spinning operation.

Wie vorstehend bereits angedeutet, kann zur Erhöhung des auf den abgezogenen Faden gegebenen Falschdralles und damit zur Verbesserung der Spinnstabilität der Offenend-Spinnvorrichtung 1 entweder ein mechanisch wirkender Wirbeleinsatz 32 eingesetzt werden, oder, wie in Figur 6 angedeutet, eine pneumatisch arbeitende Falschdrall-Blasdüseneinrichtung 33.
Diese Falschdrall-Blasdüseneinrichtung 33 weist beispielsweise einen Düseneinsatz 46 mit einigen Tangentialdüsen 42 auf.
Die Tangentialdüsen 42 sind dabei über einen Ringkanal 39 sowie eine Pneumatikleitung 40 mit einer Überdruckquelle 41 verbunden.
As already indicated above, in order to increase the false twist given to the drawn-off thread and thus to improve the spinning stability of the open-end spinning device 1, either a mechanically acting swirl insert 32 can be used, or, as indicated in FIG. 6, a pneumatically operating false twist blowing nozzle device 33 ,
This false-twist blowing nozzle device 33 has, for example, a nozzle insert 46 with a few tangential nozzles 42.
The tangential nozzles 42 are connected to an overpressure source 41 via an annular channel 39 and a pneumatic line 40.

Des weiteren kann der Kanalplattenadapter 18 mit einem Transponder 30 ausgestattet sein. Ein solcher Transponder 30 verfügt über eine feste, zweifelfrei identifizierbare Kennung, die Auskunft über die Ausstattung, des betreffenden Kanalplattenadapters 18 gibt. Der Transponder 30 ist dabei vorzugsweise ebenfalls im Bereich der zentralen Durchgangsbohrung 14 festgelegt und beispielsweise zwischen der Düsenmündung 19 und einem Verschleißschutz 31 festgeklemmt.Furthermore, the channel plate adapter 18 with a Transponder 30 may be equipped. Such a transponder 30 has a fixed, unambiguously identifiable identifier, the information about the equipment of the concerned Channel plate adapter 18 there. The transponder 30 is there preferably also in the central area Through hole 14 fixed and for example between the nozzle mouth 19 and wear protection 31 clamped.

In alternativer Ausführungsform ist allerdings auch eine farbliche Kennzeichnung des Kanalplattenadapters 18 möglich.
Das heißt, der Kanalplattenadapter 18 weist eine farbliche Markierung auf, aus der die jeweilige Ausstattung des betreffenden Kanalplattenadapters 18 leicht und eindeutig entnehmbar ist.
In an alternative embodiment, however, color coding of the channel plate adapter 18 is also possible.
This means that the duct plate adapter 18 has a colored marking from which the respective equipment of the duct plate adapter 18 in question can be easily and clearly removed.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt. Im Rahmen des allgemeinen Erfindungsgedankens sind auch weitere Kombinationen der vorbeschriebenen Einbauelemente denkbar, ohne daß dadurch'der allgemeine Erfindungsgedanke verlassen wird.The invention is not shown on the Embodiments limited. As part of the general The idea of the invention is also other combinations of Installation elements described above conceivable, without thereby'der general inventive concept is left.
