Description

Die Erfindung betrifft einen Kanalplattenadapter gemäß dem Oberbegriff des Anspruches 1.The invention relates to a channel 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 described in DE 43 34 485 A1, for example, channel plate adapter consist essentially of a preferably circular base body with a rear, conical contact surface and a mouth part which protrudes into the spinning rotor during the spinning operation and its dimensions in each case to a specific spinning rotor diameter or a Diameter range are tuned.
In this mouth part of the channel plate adapter, the mouth region of a so-called Faserleitkanales is incorporated. In addition, a centrally arranged thread withdrawal nozzle is present.

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 Kanalplatteriadapter have a central through-hole, in the input side, interchangeable, a Fadenabzugsdüse is fixed and engages in the output side, a so-called thread withdrawal tube.

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 interchangeable set in the central through-hole yarn withdrawal nozzle consists in the rule, as shown for example in DE 195 44 617 A1, from a special holding body and a non-releasably attached to the holding body, ceramic nozzle orifice.
The usually ferromagnetic holding body corresponds with corresponding in the channel plate adapter Inserted permanent magnet, which fixes him non-positively

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

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.
That is, if, for example, the spinning rotors are exchanged for smaller spinning rotors in a batch change, the channel plate adapter can be exchanged against Kanalpiattenadapter with adapted mouth part in a relatively simple manner.
Furthermore, in such a game change by appropriate choice of easily interchangeable arranged in the channel plate adapter yarn draw and the spinning material are taken into account and taken for example on the false twist distribution influence on the production 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 channel plate adapters, however, is their rather complex production and, associated with it, their relatively high price.
In addition, it may happen in exceptional cases, especially in difficult yarns that the magnetic fixation of the yarn take-off nozzle does not grab enough and rotate the yarn draw-off in their mounting hole, which has a negative effect on the resulting thread.

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 present invention seeks to provide a channel plate adapter, which is both inexpensive to manufacture and safe in its handling.

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

Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Further advantageous embodiments of the invention are the subject of the dependent claims.

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 inventive construction has the particular advantage that the production costs of such channel plate adapter can be significantly reduced by dispensing with a special holding body and the setting of the ceramic nozzle orifice directly in the central through-bore of the channel plate adapter.
That is, the channel plate adapters are so cheap that it makes sense to keep different, fully equipped channel plate adapter in stock and, if necessary, easy to change the entire channel plate adapter.
By setting the ceramic nozzle orifice directly in the central through hole not only gives a very secure connection, it can aizβerdem the dimensions of the dipping into the spinning rotor muzzle part of the channel plate adapter can be minimized, which has a positive effect particularly in spinning rotors with a small diameter or the use of spinning rotors with a diameter well below 30 mm allowed only

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 set forth in claim 2 / is provided in a preferred embodiment, that made of a ceramic material nozzle orifice is fixed by means of press fit directly in a receiving side of the central through hole arranged receiving opening insoluble.

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 of the ceramic nozzle orifice is not only a safe and cost-effective connection method, but also allows proper centering of the nozzle orifice, which has a positive effect on the yarn to be withdrawn.

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, can also be provided, the nozzle orifice in the receiving opening of the central through-hole stuck (claim 3).
Even such an adhesive bond is a safe, permanent connection method, which is inexpensive to perform.

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 set forth in claim 4, it is provided in a further advantageous embodiment that in the region of the central through-bore, preferably following the nozzle orifice, a sensor scanning the thread is arranged.
This sensor, which may be formed, for example, as a thermal sensor or as a piezoelectric sensor, is for example protected between the nozzle orifice and further arranged in the central through-hole devices and connected via a signal line to a control device of the relevant job.

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, a wear protection is also arranged in the central through hole, as described in claim 6.
This wear protection is made of a highly wear-resistant material, for example of a ceramic material, made of a hard metal or a material that is plasma-nitrided.
By using such wear protection, the life of the channel 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 a wear protection or in addition to the wear protection and a vortex insert can be arranged in the central through hole.
By such a vortex insert, which acts on the thread mechanically, additional false twist can be given to the withdrawn yarn, 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, instead of a mechanically operating vortex insert, a false twist blast nozzle device can also be provided.
Also, by such, described in claim 8 false twist blowing nozzle device, the spinning stability of the open-end spinning device can be increased, with a particularly gentle thread treatment is given because no additional mechanical stress on the deducted thread is given.

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 aforementioned devices can be inserted from the rear side into the central through-bore of the channel plate adapter and fixed there in a simple manner by a releasably arranged locking insert (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 features of the channel plate adapter can, as described in claim 10, be made visible in a simple manner by a color coding of the channel plate adapter or, as set forth in claim 5, by a definable in the central through hole of the channel plate adapter transponder.
Such labeled channel plate adapters are clearly identifiable and can be easily used or replaced according to the particular requirements.

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

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 apparatus 1 shown in FIG. 1 has, as is known, a rotor housing 2, in which a spinning rotor 3 rotates at high speed during the spinning operation. The spinning rotor 3 is with its rotor shaft 22 in the Lagerzwickeln a support disk bearing 4 supported and is fixed in the axial direction by an example permanent magnetic thrust bearing 21.

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 Tangentialnemen 5, which is employed by a support roller 44 to the rotor shaft 22.
The per se forwardly open rotor housing 2 is connected via a suction line 6 to a (not shown) vacuum source and closed during the spinning operation forward / by a so-called fiber channel plate 45.
The fiber channel plate 45, which is arranged on a lid element 7 rotatably mounted limitedly about a pivot axis 16, bears against the end face of the rotor housing 2 with a lip sealing element 17.

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 the cover element 7 also a Faserbandzuführ- and - dissolver 8 is integrated, which includes, inter alia, a sliver pick-up roller 9, a sliver draw-in cylinder 10 and a Faserleitkanal 11.
As shown in FIG. 1, the sliver-opening roller 9 is driven, for example, by a tangential belt 12, while the sliver-intake 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 an open toward the spinning rotor 3 receptacle 13 is incorporated, which has a circular, conical contact surface 24. In this recording 13 is aligned with angular accuracy, with its base body 26, a channel plate adapter 18 easily releasably fixed

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, whose various. Embodiment variants will be explained in more detail below with reference to Figures 2 to 6, has. Via a central through hole 14. In the through hole 14 on the input side made of a ceramic material nozzle orifice 19 is fixed. On the output side, a so-called thread withdrawal tube 20 engages in the central passage 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 whose diameter lies slightly below the diameter of the head part 27 of the nozzle orifice 19 of the yarn draw-off nozzle 23
That is, the nozzle orifice 19 can be pressed with its head part 27 in the Aufnahmeöffnurig 28 and fixed there inextricably by means of 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, however, the diameter of the receiving opening 28 may also be slightly above the diameter of the head part 27 of the nozzle orifice 19.
In this case, the nozzle orifice 19 is glued into the channel plate adapter 18.
Even such a permanent connection is very safe and easy.

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 be further seen from FIG. 2, it is behind the central passage bore 14 in the thread running direction the nozzle mouth 19, further arranged a wear protection 31, which is interchangeably fixed by a locking element 34, which consists for example of a clamping sleeve 36 and a hexagon socket screw 35. In a preferred embodiment, the wear protection 31 is made of a ceramic material, a hard metal or 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 vertebral 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 slightly modified.
That is, instead of a hexagon socket screw, the central through hole 14 at the end of a thread for receiving a special threaded insert 37.
The threaded insert 37, which is equipped with an external thread, then fixes the swirl insert 32 or the wear contactor 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 29 arranged in the region of the central through-bore 14.
This scanning the current thread sensor 29 is formed for example as a thermal sensor or as a piezoelectric sensor and connected, for example via a signal line 38 to a workstation's own control device 43. The sensor 29 allows reliable monitoring of the withdrawn via the nozzle orifice 19 during 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 applied to the withdrawn yarn and thus to improve the spinning stability of the open-end spinning device 1, either a mechanically acting whirling insert 32 can be used or, as indicated in FIG. 6, a pneumatically operating false twisting blower device 33 ,
This false twist blast nozzle device 33 has, for example, a nozzle insert 46 with a few tangential nozzles 42.
The tangential nozzles 42 are connected via an annular channel 39 and a pneumatic line 40 with a pressure source 41.

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 may be equipped with a transponder 30. Such a transponder 30 has a fixed, undoubtedly identifiable identifier that provides information about the features of the relevant channel plate adapter 18. The transponder 30 is preferably also defined in the region of the central through-bore 14 and, for example, clamped between the nozzle orifice 19 and a wear protection 31.

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, a color coding of the channel plate adapter 18 is possible.
That is, the channel plate adapter 18 has a colored marking, from which the respective equipment of the respective channel plate adapter 18 is easily and clearly removable.

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 limited to the illustrated embodiments. Within the scope of the general concept of the invention, other combinations of the above-described installation elements are conceivable without thereby abandoning the general inventive idea.
