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
Derartige beispielsweise in der
In dieses Mündungsteil des Kanalplattenadapters ist der Mündungsbereich eines sogenannten Faserleitkanales eingearbeitet. Außerdem ist eine zentrisch angeordnete Fadenabzugsdüse vorhanden.Such as in the
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
Der in der Regel ferromagnetische Haltekörper korrespondiert dabei mit entsprechenden in den Kanalplattenadapter eingelassenen Permanentmagnet einsätzen, die ihn kraftschlüssig fixierendeThe interchangeable set in the central through-hole yarn withdrawal nozzle consists in the rule, such as in the
The ferromagnetic holding body usually corresponds with appropriate recessed in the channel plate adapter permanent magnet inserts, 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
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 ermöglichteThe 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 1 ausgeführt, ist die aus einem keramischen Werkstoff gefertigte Düsenmündung mittels Preßsitz direkt in einer eingangsseitig der zentralen Durchgangsbohrung angeordneten Aufnahmeöffnung unlösbar festgelegt.As stated in
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.
Wie im Anspruch 2 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
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 fixed and a signal line to a control device of the relevant Workstation connected.
In vorteilhafter Ausführungsform ist in der zentralen Durchgangsbohrung außerdem, wie im Anspruch 4 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 4.
This wear protection is made of a highly wear-resistant material, for example made of a ceramic material, 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 5 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
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 6 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
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 7).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 7).
Die jeweilige Ausstattung des Kanalplattenadapters kann dabei, wie im Anspruch 8 beschrieben, auf einfache Weise durch eine farbliche Kennzeichnung des Kanalplattenadapters sichtbar gemacht werden oder, wie im Anspruch 3 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
Such labeled channel plate adapters are clearly identifiable and can be easily used or replaced according to the particular requirements.
