Definitions
- the invention relates to a device for applying a liquid to a running thread according to the preamble of claim 1.
- a liquid is preferably supplied to an oil-water emulsion.
- the application of the liquid must be particularly evenly generated on the thread to ensure uniform physical properties.
- the thread is usually guided with contact via a wetting surface on which the liquid emerges as continuously as possible.
- a wetting surface on which the liquid emerges as continuously as possible is for example from the DE 199 45 699 A1 known.
- the thread for applying the liquid is guided with contact over a wetted wetting surface.
- the wetting surface is formed on a wetting body having a plurality of distributed openings in the wetting surface which are connected to a supply channel for supplying the liquid.
- the wetting body is formed for this purpose from a porous material, so that the supply of the liquid takes place via a plurality of capillaries.
- Such wetting bodies are preferably formed of sintered ceramic materials whose arrangement and distribution of the capillary and pore-shaped openings is very irregular. Thus, a uniform distribution over the entire wetting surface and thus an exact dosage is not possible.
- Another object of the invention is to provide a generic device for applying a liquid to a running thread through which even fast-running threads are wetted.
- the wetting body is formed by a plate stack of a plurality of plates, that each plate has a longitudinal groove at least on one side surface and that the plates with a plate edge form the wetting surface in which open the longitudinal grooves.
- the invention is characterized in that within a thread running track a defined number of openings are present, which supply the liquid of the wetting surface and thus in the running thread.
- the number of arranged within the plate stack plates form a wetting distance, in which open the longitudinal grooves of the plates.
- the length of the wetting distance can thus be determined solely by the choice of the number of plates. In this way, it is possible to produce particularly long wetting distances in order to produce, for example, liquid application defined on fast running threads.
- the development of the invention is preferably used, in which the plates each have a plate opening penetrating the longitudinal groove and in which the plate openings of the plates within the plate stack collectively form the supply channel.
- the preferably plane-parallel plates can thus be held together within the plate stack in such a way that a liquid is supplied directly under pressure to the feed channel formed by the plate openings.
- Each of the longitudinal grooves formed on the plates can thus be fed from the supply channel under the same conditions with a liquid flow.
- the development of the invention has proven in which the plates each have at the plate edge a crossing of the longitudinal groove crossing transverse groove and that arranged in a row transverse grooves of the plates within the plate stack form the wetting surface.
- the transverse grooves allow a linear guide of the thread over the plate stack, so that constant lengths of the wetting gap can be met without significant additional thread guide elements.
- the longitudinal grooves on the plates are preferably formed with a throttle point, which are arranged upstream of the openings in the wetting surface. This allows flow resistances to be produced which, even with the smallest pressure fluctuations, do not lead to any significant dosing deviations.
- the throttle points can be formed by cross-sectional changes, groove loops or multi-part grooves.
- the plates each have a plurality of spaced apart on a side surface formed longitudinal grooves and a plurality of longitudinal grooves associated plate bores.
- the plates can form parallel next to each other, in which open at a distance formed longitudinal grooves.
- the development of the invention is preferably used, in which the plates each have a plurality of spaced at the plate edge formed transverse grooves, in which the longitudinal grooves open.
- the threads can each be assigned to a thread running track assigned by the transverse grooves.
- the development of the device according to the invention is provided, in which the plates of the plate stack between a terminal block and a holding block are held, which are connected via screw means.
- individual sealing means may be provided between adjacent plates in order to seal the longitudinal grooves and the plate bores.
- elastic sealing means are preferably used, so that the plates are held against each other with little tension.
- connection block is hereby preferably used to receive a fluid connection, which is connected via a distributor bore with the supply channel of the plate stack.
- connection block is preferably designed with a plurality of fluid connections, so that each supply channel is assigned its own fluid connection.
- each supply channel is assigned its own fluid connection.
- a first embodiment of the device according to the invention for applying a liquid is shown on a running thread.
- the embodiment is in a longitudinal sectional view and in Fig. 2 shown in a cross-sectional view.
- the device according to the invention consists of a plate stack 1, which is formed from a plurality of thin plates 5.
- the thickness of the plates 5 is in the range of 0.5 mm to 10 mm.
- the plates 5 are placed side by side on a base plate 18 and are held at both ends of the plate stack 1 by a terminal block 11 and an opposite holding block 13.
- the terminal block and the holding block 13 are connected to each other via a screw means 14, so that the plates 5 within the plate stack 1 sealingly abut each other.
- the plates 5 are constructed identically.
- a cross section of the plate 5 is made Fig. 1 and a side view of the plate 5 is made Fig. 2 refer to.
- the plate 5 has a longitudinal groove 8 on a side surface 16 in the middle region.
- the longitudinal groove 8 extends between an upper edge of the plate 7 to a plate opening 6 penetrating the plate 5.
- the plate opening 6 passes completely through the plate 5.
- the plate openings 6 within the plate stack 1 form a continuous supply channel 4.
- the supply channel 4 is coupled to a liquid connection 15 via a distributor bore 12 in the connection block 11.
- the longitudinal grooves 8 are formed on one side, so that within the plate stack 1, the longitudinal grooves 8 each form between adjacent plates 5 longitudinal channels that connect the supply channel 4 with an upper wetting surface 2.
- the opening in the wetting surface 2 longitudinal grooves 8 form the openings 3, from which emerges during operation, the liquid required for application.
- the plate edge 7 of the plates 5 to form the wetting surface 2 is slightly convex, so that a thread in the central region of the plates 5 is guided.
- the plates 5 are arranged on a flat base plate 18. Basically, there is the possibility that the base plate 18 has a curvature, so that the plates 5 within the plate stack 1 offset from each other, so that a curved thread running track adjusts to the wetting surface 2. Thus, the contact between a thread and the wetting surface 2 can be improved.
- the plates 5 are held together within the plate stack such that the side surfaces each form a sealing joint to prevent liquid leakage from the longitudinal grooves and the plate openings.
- a respective sealing means between the adjacent plates.
- very thin gaskets of paper or other sealing material could be placed between adjacent plates within the plate stack.
- elastic sealants are preferably disposed between the plates to bias the plates within the plate stack.
- FIG. 3 a further embodiment of the device according to the invention is shown schematically in a cross-sectional view.
- the embodiment is essentially identical to the aforementioned embodiment according to Fig. 1 and 2 , so that only the essential differences are explained here.
- each plate 5 on the plate edge 7 a transverse groove 10, in the groove bottom, the longitudinal groove 8 opens.
- the groove bottom 9 of the transverse groove 10 forms the wetting surface 2.
- the longitudinal groove 8 is also formed with a throttle point 17, which in this case also by a first longitudinal portion 19.1 and a second formed by a plurality of fine grooves 20 section is.
- the fine grooves 20 thereby form the openings 3 in the groove bottom 9 of the transverse groove 10.
- only one of the side surface 16 of the plate is formed with a longitudinal groove.
- the longitudinal section section 19.1 of the groove opens into the plate opening 6.
- the plates 5 held side by side in the plate stack 1 are aligned in such a way that the transverse grooves 10 form a thread running track with the wetting surface 2.
- a liquid for example a water-oil emulsion is supplied under pressure via the liquid connection 15.
- the liquid passes through the distributor bore 12 into the supply channel 4 formed by the plate openings 6.
- the liquid arranged between the plates 5 guides the liquid to the plate edges 7 and emerges from the openings 3 formed by the longitudinal grooves 8. In this case, the thread is guided over the plate edges 7 of the assembled plates, which form the wetting surface 2.
- Fig. 4 shows the embodiment in a cross-sectional view
- Fig. 5 a plan view of the embodiment is shown.
- the plate stack 1 is also formed from a plurality of plates 5.
- the plates 5 are identical and have on a side surface 16 a plurality of spaced longitudinal grooves 8.1, 8.2 and 8.3.
- the longitudinal grooves 8.1, 8.2 and 8.3 each extend between a transverse groove and a supply channel.
- the plate 5 on three side by side formed plate openings 6.1, 6.2 and 6.3.
- At the plate edge 7 and the plate 5 are three spaced apart formed transverse grooves 10.1, 10.2 and 10.3 formed. In each of the transverse grooves 10.1, 10.2 and 10.3 can thus lead a thread for applying the liquid.
- each supply channel 4.1, 4.2, and 4.3 within the plate stack a liquid connection 15.1, 15.2 and 15.3 in the terminal block 11 is assigned.
- the liquid connections 15.1, 15.2 and 15.3 are coupled via the distributor bores 12.1, 12.2 and 12.3 to the supply channels 4.1, 4.2 and 4.3.
- the plates 5 of the plate stack 1 are held between the terminal block 11 and a holding block 13, the plates 5 being mounted on a base plate 18.
- the terminal block 11 and the holding block 13 are connected to each other via a plurality of screw 14.
- the throttle body 17 is formed in the longitudinal groove 8 by a groove loop 21.

- the liquid chamber 22 is connected within the connection block 11 via a distributor bore 12 with a liquid connection.
- the liquid used for wetting a thread can be introduced into the liquid chamber 22 via the liquid connection 15 and the distributor bore 12.
- the liquid chamber 22 is thereby completely filled with the liquid, so that with increasing liquid pressure, the liquid automatically penetrates through the openings 3.2 in the longitudinal grooves 8 of the plates 5.
- the liquid emerging at the upper plate edge 7.1 from the openings 3.1 can be dosed by the geometric configuration of the longitudinal groove 8 and by the fluid pressure within the liquid chamber 22.
- the wetting surface 2 could according to the embodiment according to Fig. 2 or the embodiment according to Fig. 3 be educated.

Description
Die Erfindung betrifft eine Vorrichtung zum Auftragen einer Flüssigkeit auf einen laufenden Faden gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for applying a liquid to a running thread according to the preamble of
Bei der Herstellung und Verarbeitung von synthetischen Fäden ist es allgemein bekannt, dass dem Faden zur Verbesserung der Laufeigenschaften sowie insbesondere zum Zusammenhalt der den Faden bildenden Filamentschar eine Flüssigkeit vorzugsweise eine Öl-Wasser-Emulsion zugeführt wird. Der Auftrag der Flüssigkeit muss zur Gewährleistung gleichmäßiger physikalischer Eigenschaften besonders gleichmäßig an dem Faden erzeugt werden. Hierzu wird der Faden üblicherweise mit Kontakt über eine Benetzungsoberfläche geführt, an welcher die Flüssigkeit möglichst kontinuierlich austritt. Eine derartige Vorrichtung ist beispielsweise aus der
Bei der bekannten Vorrichtung wird der Faden zum Auftragen der Flüssigkeit mit Kontakt über eine benetzte Benetzungsoberfläche geführt. Die Benetzungsoberfläche ist an einem Benetzungskörper ausgebildet, der mehrere verteilt angeordnete Öffnungen in der Benetzungsoberfläche aufweist, die mit einem Versorgungskanal zur Zuführung der Flüssigkeit verbunden sind. Bei der bekannten Vorrichtung ist der Benetzungskörper zu diesem Zweck aus einem porösen Material gebildet, so dass die Zuführung der Flüssigkeit über eine Vielzahl von Kapillaren erfolgt. Derartige Benetzungskörper sind vorzugsweise aus Sinterkeramikwerkstoffen gebildet, deren Anordnung und Verteilung der Kapillare und porenförmigen Öffnungen sehr unregelmäßig ist. Somit ist eine gleichmäßige Verteilung über die gesamte Benetzungsoberfläche und somit eine exakte Dosierung nicht möglich.In the known device, the thread for applying the liquid is guided with contact over a wetted wetting surface. The wetting surface is formed on a wetting body having a plurality of distributed openings in the wetting surface which are connected to a supply channel for supplying the liquid. In the known device, the wetting body is formed for this purpose from a porous material, so that the supply of the liquid takes place via a plurality of capillaries. Such wetting bodies are preferably formed of sintered ceramic materials whose arrangement and distribution of the capillary and pore-shaped openings is very irregular. Thus, a uniform distribution over the entire wetting surface and thus an exact dosage is not possible.
Aus der
Es ist somit Aufgabe der Erfindung eine Vorrichtung zum Auftragen einer Flüssigkeit auf einen laufenden Faden der gattungsgemäßen Art bereitzustellen, mit welcher der Auftrag der Flüssigkeit gleichmäßig dosiert an dem Faden erzeugt wird.It is therefore an object of the invention to provide a device for applying a liquid to a running thread of the generic type, with which the application of the liquid is uniformly metered generated on the thread.
Ein weiteres Ziel der Erfindung liegt darin, eine gattungsgemäße Vorrichtung zum Auftragen einer Flüssigkeit auf einen laufenden Faden bereitzustellen, durch welche auch schnell laufende Fäden benetzbar sind.Another object of the invention is to provide a generic device for applying a liquid to a running thread through which even fast-running threads are wetted.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Benetzungskörper durch einen Plattenstapel aus mehreren Platten gebildet ist, dass jede Platte zumindest an einer Seitenfläche eine Längsnut aufweist und dass die Platten mit einem Plattenrand die Benetzungsoberfläche bilden, in welcher die Längsnuten münden.This object is achieved in that the wetting body is formed by a plate stack of a plurality of plates, that each plate has a longitudinal groove at least on one side surface and that the plates with a plate edge form the wetting surface in which open the longitudinal grooves.
Vorteilhafte Weiterbildungen der Erfindung sind durch die Merkmale und Merkmalskombinationen der jeweiligen Unteransprüche definiert.Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.
Die Erfindung zeichnet sich dadurch aus, dass innerhalb einer Fadenlaufspur eine definierte Anzahl von Öffnungen vorhanden sind, die die Flüssigkeit der Benetzungsoberfläche und damit im laufenden Faden zuführen. Die Anzahl der innerhalb des Plattenstapels angeordneten Platten bilden eine Benetzungsstrecke, in welcher die Längsnuten der Platten münden. Die Länge der Benetzungsstrecke lässt sich somit allein durch die Wahl der Anzahl der Platten bestimmen. Damit können auch besonders lange Benetzungsstrecken erzeugt werden, um beispielsweise an schnell laufenden Fäden definierten Flüssigkeitsauftrag zu erzeugen.The invention is characterized in that within a thread running track a defined number of openings are present, which supply the liquid of the wetting surface and thus in the running thread. The number of arranged within the plate stack plates form a wetting distance, in which open the longitudinal grooves of the plates. The length of the wetting distance can thus be determined solely by the choice of the number of plates. In this way, it is possible to produce particularly long wetting distances in order to produce, for example, liquid application defined on fast running threads.
Um an den Längsnuten der Platten gleiche Fließeigenschaften und Fließwiderstände zu erhalten, ist die Weiterbildung der Erfindung bevorzugt verwendet, bei welcher die Platten jeweils eine die Längsnut durchdringende Plattenöffnung aufweisen und bei welcher die Plattenöffnungen der Platten innerhalb des Plattenstapels gemeinschaftlich den Versorgungskanal bilden. Die vorzugsweise planparallelen Platten lassen sich so innerhalb des Plattenstapels gemeinschaftlich derart zusammenhalten, dass eine Flüssigkeit unmittelbar unter Druck dem durch die Plattenöffnungen gebildeten Versorgungskanal zugeführt wird. Jede der an den Platten ausgebildeten Längsnut lässt sich somit unter gleichen Bedingungen aus dem Versorgungskanal mit einem Flüssigkeitsstrom speisen.In order to obtain the same flow properties and flow resistance at the longitudinal grooves of the plates, the development of the invention is preferably used, in which the plates each have a plate opening penetrating the longitudinal groove and in which the plate openings of the plates within the plate stack collectively form the supply channel. The preferably plane-parallel plates can thus be held together within the plate stack in such a way that a liquid is supplied directly under pressure to the feed channel formed by the plate openings. Each of the longitudinal grooves formed on the plates can thus be fed from the supply channel under the same conditions with a liquid flow.
Zur Fadenführung und Benetzung des Fadens hat sich die Weiterbildung der Erfindung bewährt, bei welcher die Platten jeweils an dem Plattenrand eine die Mündung der Längsnut kreuzende Quernut aufweisen und dass die in einer Reihe angeordneten Quernuten der Platten innerhalb des Plattenstapels die Benetzungsoberfläche bilden. Die Quernuten ermöglichen eine geradlinige Führung des Fadens über den Plattenstapel, so dass konstante Längen der Benetzungsstrecke ohne wesentliche zusätzliche Fadenführungselemente eingehalten werden können.For thread guidance and wetting of the thread, the development of the invention has proven in which the plates each have at the plate edge a crossing of the longitudinal groove crossing transverse groove and that arranged in a row transverse grooves of the plates within the plate stack form the wetting surface. The transverse grooves allow a linear guide of the thread over the plate stack, so that constant lengths of the wetting gap can be met without significant additional thread guide elements.
Je nach Fadentiter besteht auch die Möglichkeit, dass eine Vergrößerung der Längsnuten zwischen zwei benachbarten Platten dadurch erreicht wird, dass die Platten jeweils zwei sich an den Seitenflächen gegenüberliegende Längsnuten aufweisen. Somit wirken die sich gegenüberliegenden Längsnuten in benachbarten Platten gemeinschaftlich, um die Flüssigkeit aus dem Versorgungskanal zur Benetzungsoberfläche zu führen.Depending on the thread denier, there is also the possibility that an enlargement of the longitudinal grooves between two adjacent plates is achieved in that the plates each have two longitudinal grooves lying opposite one another on the side surfaces. Thus, the opposing longitudinal grooves in adjacent plates cooperate to direct the liquid from the supply channel to the wetting surface.
Um an den Längsnuten eine möglichst feinfühlig Dosierung einstellen zu können, sind die Längsnuten an den Platten bevorzugt mit einer Drosselstelle ausgebildet, die den Öffnungen in der Benetzungsoberfläche vorgeordnet sind. Damit lassen sich Fließwiderstände erzeugen, die auch bei kleinsten Druckschwankungen zu keinen wesentlichen Dosierabweichungen führen. Die Drosselstellen können hierbei durch Querschnittveränderungen, Nutschleifen oder mehrteilige Nuten gebildet sein.In order to be able to set the most sensitive possible dosage on the longitudinal grooves, the longitudinal grooves on the plates are preferably formed with a throttle point, which are arranged upstream of the openings in the wetting surface. This allows flow resistances to be produced which, even with the smallest pressure fluctuations, do not lead to any significant dosing deviations. The throttle points can be formed by cross-sectional changes, groove loops or multi-part grooves.
In Schmelzspinnprozessen ist es üblich, dass mehrere Fäden im engen Abstand nebeneinander gleichzeitig benetzt werden müssen. Hierzu ist die Weiterbildung der Erfindung besonders vorteilhaft, bei welcher die Platten jeweils mehrere mit Abstand zueinander an einer Seitenfläche ausgebildete Längsnuten und mehrere den Längsnuten zugeordnete Plattenbohrungen aufweisen. So lassen sich am Plattenrand mehrere Fadenlaufspuren parallel nebeneinander ausbilden, in denen mit Abstand ausgebildete Längsnuten münden.In melt spinning processes, it is common for several threads to be wetted adjacent to one another at close intervals. For this purpose, the development of the invention is particularly advantageous, in which the plates each have a plurality of spaced apart on a side surface formed longitudinal grooves and a plurality of longitudinal grooves associated plate bores. Thus, at the edge of the plate several yarn tracks can form parallel next to each other, in which open at a distance formed longitudinal grooves.
Um möglichst kurze Fadenabstände bei der Führung der Fadenschar einhalten zu können, ist die Weiterbildung der Erfindung bevorzugt verwendet, bei welcher die Platten jeweils mehrere mit Abstand an dem Plattenrand ausgebildete Quernuten aufweisen, in welchen die Längsnuten münden. Damit lassen sich die Fäden jeweils einer durch die Quernuten zugeordnete Fadenlaufspur zuordnen.In order to comply with the shortest possible thread intervals in the leadership of the group of threads, the development of the invention is preferably used, in which the plates each have a plurality of spaced at the plate edge formed transverse grooves, in which the longitudinal grooves open. In this way, the threads can each be assigned to a thread running track assigned by the transverse grooves.
Um die innerhalb des Plattenstapels die Platten möglichst druckdicht aneinander zu halten, ist die Weiterbildung der erfindungsgemäßen Vorrichtung vorgesehen, bei welcher die Platten des Plattenstapels zwischen einem Anschlussblock und einem Halteblock gehalten sind, die über Schraubmittel verbunden sind. Damit ist eine Fixierung des Plattenstapels gewährleistet. Dabei können zwischen benachbarten Platten einzelne Dichtungsmittel vorgesehen sein, um die Längsnuten und die Plattenbohrungen abzudichten. Hierbei werden bevorzugt elastische Dichtungsmittel verwendet, so dass die Platten mit geringer Verspannung gegeneinander gehalten sind.In order to keep the plates within the plate stack as pressure-tight as possible, the development of the device according to the invention is provided, in which the plates of the plate stack between a terminal block and a holding block are held, which are connected via screw means. For a fixation of the plate stack is guaranteed. In this case, individual sealing means may be provided between adjacent plates in order to seal the longitudinal grooves and the plate bores. In this case, elastic sealing means are preferably used, so that the plates are held against each other with little tension.
Der Anschlussblock wird hierbei bevorzugt dazu genutzt, um einen Flüssigkeitsanschluss aufzunehmen, der über eine Verteilerbohrung mit dem Versorgungskanal des Plattenstapels verbunden ist.The connection block is hereby preferably used to receive a fluid connection, which is connected via a distributor bore with the supply channel of the plate stack.
Zum Behandeln mehrerer Fäden gleichzeitig ist der Anschlussblock bevorzugt mit mehreren Flüssigkeitsanschlüssen ausgebildet, so dass jedem Versorgungskanal ein eigener Flüssigkeitsanschluss zugeordnet ist. Damit ist eine gleichmäßige Zuführung und Auftragung der Flüssigkeit in jedem der Fäden möglich.For treating a plurality of threads at the same time, the connection block is preferably designed with a plurality of fluid connections, so that each supply channel is assigned its own fluid connection. Thus, a uniform supply and application of the liquid in each of the threads is possible.
Die Erfindung wird nachfolgend anhand einiger Ausführungsbeispiele der erfindungsgemäßen Vorrichtung unter Hinweis auf die beigefügten Zeichnungen näher erläutert.The invention will be explained in more detail with reference to some embodiments of the device according to the invention with reference to the accompanying drawings.
