Description

Die Erfindung betrifft eine Vorrichtung an einer Spinnereivorbereitungsmaschine, z. B. Karde, zur Messung von Abständen zwischen den garnierten Deckelstäben eines Wanderdeckelaggregats und der garnierten Trommel, bei der mindestens ein Sensor vorhanden ist, mit dem der Spitzenabstand (Kardierabstand) zwischen den garnierten Flächen erfassbar ist, wobei der Sensor einem Deckelstab zugeordnet ist und der Trommelgarnitur gegenüberliegend angeordnet ist.The invention relates to a device on a spinning preparation machine, z. As carding, for measuring distances between the garnished flat bars of a moving lid unit and the garnished drum, in which at least one sensor is present, with the tip spacing (carding) between the garnished surfaces can be detected, the sensor is associated with a flat bar and the Drum set is arranged opposite.

Bei einer bekannten Vorrichtung ( EP 0 801 158 A ) ist eine Kardierspalteinstellung mittels Lasersensor bekannt. Dieses Konzept sieht vor, dass ein Laserstrahl von der einen Maschinenseite durch den Kardierspalt auf die gegenüberliegende Maschinenseite gesendet wird. Eine Empfangseinrichtung registriert die Laserstrahlen, die durch die engste Stelle des Kardierspalts hindurchgesendet werden. Über eine Auswertungselektronik wird ein minimaler Kardierspalt angegeben. Weicht der gemessene Kardierspalt vom Soll-Abstand ab, ermöglicht eine Steuerung das Nachstellen des Kardierspalts. Angesteuerte Motoren verstellen beidseitig die Flexibelbögen auf denen die Deckelstäbe aufliegen, um somit den Kardierspalt zu vergrößern oder zu verringern. Diese Methode ist allerdings nur im Maschinenbetrieb ohne Fasermaterial möglich. Während der Produktion würden die Fasern im Kardierspalt den Laserstrahl unterbrechen, so dass der Empfänger kein Eingangssignal mehr erhält.In a known device ( EP 0 801 158 A ) is a Kardierspalteinstellung known by laser sensor. This concept provides that a laser beam is sent from one side of the machine through the carding nip to the opposite side of the machine. A receiving device registers the laser beams that are transmitted through the narrowest point of the carding nip. An evaluation electronics specifies a minimum carding gap. If the measured carding gap deviates from the nominal distance, a controller makes it possible to readjust the carding gap. Controlled motors adjust on both sides the flexible arches on which the flat bars rest, in order to increase or decrease the carding gap. These However, this method is only possible in machine operation without fiber material. During production, the fibers in the carding nip would interrupt the laser beam so that the receiver no longer receives any input signal.

Nach einem weiteren Vorschlag ( DE 39 13 996 A ) ist zur Kardierspaltmessung ein Fühler vorgesehen. Auf beiden Maschinenseiten außerhalb der Garniturflächen ermitteln Abstandsmessfühler (induktive oder kapazitive Sensoren) den vorliegenden Abstand zwischen Deckelstabführung und Tambour. Eine Steuerung kann Differenzen zwischen IST- und SOLL-Abstand über Verstellung der Deckelstabführung ausgleichen. Ein Nachteil besteht darin, dass die kritische Durchbiegung der Deckelstäbe in der Mitte der Maschinen nicht erfasst wird.After another proposal ( DE 39 13 996 A ) is provided for Kardierspaltmessung a sensor. Distance sensors (inductive or capacitive sensors) determine the distance between the flat bar guide and the drum on both machine sides outside the clothing surfaces. A controller can compensate for differences between actual and nominal distance by adjusting the flat bar guide. A disadvantage is that the critical deflection of the flat bars in the middle of the machines is not detected.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile beseitigt, die insbesondere eine berührungslose Kardierspaltmessung unter Produktionsbedingungen ermöglicht und eine drahtlose Übertragung der Messdaten an eine Auswerteeinrichtung erlaubt.The invention is therefore an object of the invention to provide a device of the type described above, which eliminates the disadvantages mentioned, which allows in particular a non-contact carding gap measurement under production conditions and allows wireless transmission of the measured data to an evaluation.

Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.The solution of this object is achieved by the characterizing features of claim 1.

Dadurch, dass der mindestens eine Sensor in dem Deckelstab integriert ist und eine drahtlose Signalübertragung vorhanden ist, ist es ermöglicht, dass der Kardierspalt während der Produktion mit Fasermaterialdurchsatz gemessen wird. Vorteilhaft ist ferner, dass es die drahtlose Signalübertragung in Kombination mit der Intergretation der Messelektronik in einen weiteren Deckelstab erlaubt, dass die Karde geschlossen bleibt und alle Sicherheitseinrichtungen in Betrieb bleiben. Hierdurch kann auch ein einfach eingewiesener Benutzer das Messsystem verwenden.The fact that the at least one sensor is integrated in the flat bar and there is wireless signal transmission allows the carding nip to be measured during fiber material throughput production. A further advantage is that it allows the wireless signal transmission in combination with the integration of the measuring electronics in a further flat bar that the card remains closed and all safety devices remain in operation. As a result, even a simple trained user can use the measuring system.

Die erfindungsgemäße Vorrichtung ermöglicht es, den Kardierspalt am Wanderdeckel berührungslos während der Produktion, also ohne Beeinflussung des Messergebnisses durch Fasermaterial, kontinuierlich zu bestimmen. Weiterhin wird durch das System die Karde unter realen Bedingungen betrieben, beispielsweise mit geschlossenen Türen. Da der Kardierspalt besonders von den Temperaturverhältnissen in der Karde abhängig ist, besteht ein Unterschied zwischen einer Messung mit offenen und geschlossenen Türen, da hierdurch die Temperaturverhältnisse verändert werden.The device according to the invention makes it possible to continuously determine the carding gap on the revolving lid without contact during production, that is to say without influencing the measurement result by means of fiber material. Furthermore, the card is operated by the system under real conditions, for example with closed doors. Since the carding gap is particularly dependent on the temperature conditions in the card, there is a difference between a measurement with open and closed doors, as this changes the temperature conditions.

Die Erfindung wird nachfolgend anhand von zeichnerisch dargestellten Ausführungsbeispielen näher erläutert.The invention will be explained in more detail with reference to exemplary embodiments illustrated in the drawings.

Fig. 1 zeigt eine Karde, z. B. Trützschler Karde TC, mit Speisewalze 1, Speisetisch 2, Vorreißern 3a, 3b, 3c, Trommel 4, Abnehmer 5, Abstreichwalze 6, Quetschwalzen 7, 8, Vliesleitelement 9, Flortrichter 10, Abzugswalzen 11, 12, Wanderdeckel 13 mit Deckelumlenkrollen 13a, 13b und garnierten Deckelstäben 14, Kanne 15 und Kannenstock 16. Die Drehrichtungen der Walzen sind mit gebogenen Pfeilen gezeigt. Mit M ist der Mittelpunkt (Achse) der Trommel 4 bezeichnet. 4a gibt die Garnitur (Sägezahngarnitur) und 4b gibt die Drehrichtung der Trommel 4 an. 5a gibt die Garnitur (Sägezahngarnitur) und 5b gibt die Drehrichtung des Abnehmers 5 an. Mit B ist die Drehrichtung des Wanderdeckels 13 in Kardierstellung und mit C ist die Rücktransportrichtung der Deckelstäbe 14, mit 31', 31" sind Funktionselemente und mit 13a und 13b sind Deckelumlenkrollen bezeichnet. Der Pfeil A bezeichnet die Arbeitsrichtung. Die Sägezahngarnituren 4a und 5a (Ganzstahlgarnituren) sind als separate Bauelemente auf die Walzengrundkörper der Trommel 4 bzw. des Abnehmers 5 aufgezogen. Fig. 1 shows a card, z. B. Trützschler carding TC, with feed roller 1, dining table 2, lickers 3a, 3b, 3c, drum 4, pickup 5, skimmer 6, nip rollers 7, 8, Vliesleitelement 9, trimming funnel 10, take-off rollers 11, 12, revolving lid 13 with Deckelumlenkrollen 13a , 13b and garnished flat bars 14, jug 15 and can stock 16. The directions of rotation of the rollers are shown with curved arrows. M denotes the center point (axis) of the drum 4. 4a indicates the set (Sägezahngarnitur) and 4b indicates the direction of rotation of the drum 4 at. 5a indicates the set (saw tooth set) and 5b indicates the direction of rotation of the pickup 5. B is the direction of rotation of the traveling lid 13 in the carding position and C is the return transport direction of the flat bars 14, 31 ', 31 "are functional elements and 13a and 13b are cover deflecting rollers The arrow A designates the working direction The sawtooth sets 4a and 5a (FIG. Ganzstahlgarnituren) are mounted as separate components on the roller body of the drum 4 and der Abnehmers 5.

Nach Fig. 2 ist das Konzept für das Messdeckelsystem ein Messdeckelstab 14d mit separatem Transportdeckel (17). Im Messdeckelstab 14d befinden sich die Sensoren 18a, 18b, 18c (sh. Fig. 7) zur Temperatur- und Kardierspaltmessung, während der Transportdeckel 17 die Elektronik, Stromversorgung und Datenübertragung beinhaltet. Diese beiden Elemente sind über Kabelleitungen 19 miteinander verbunden, während die Daten vom Transportdeckel 17 kabellos an eine Auswerteeinheit 20 (sh. Fig. 6) außerhalb der Karde übertragen werden. Die Abmaße des Transportdeckels 17 sind derart gewählt, dass die Platinen der Wirbelstromsensoren problemlos eingesetzt werden können. Durch die deutliche Abweichung der Bauform des Transportdeckels 17 von einem normalen Deckelstab 14 ist es nicht möglich, links und rechts neben dem Transportdeckel 17 normale Deckelstäbe 14 einzusetzen. An diesen Positionen sind zwei Zwischendeckel 21a, 21 b vorgesehen. Die Zwischendeckel schließen die Lücken zwischen dem Transportdeckel 17 und den angrenzenden Deckelstäben 14, damit an diesen Stellen keine Fasern aus dem unter Überdruck stehenden Kardierspalt ausgeblasen werden.To Fig. 2 the concept for the measuring cover system is a measuring cover rod 14d with a separate transport cover (17). The measuring cover rod 14d contains the sensors 18a, 18b, 18c (see FIG. Fig. 7 ) for temperature and carding gap measurement, while the transport cover 17 includes the electronics, power supply and data transmission. These two elements are connected to each other via cable lines 19, while the data from the transport cover 17 wirelessly to an evaluation unit 20 (see FIG. Fig. 6 ) are transferred outside the card. The dimensions of the transport cover 17 are selected such that the boards of the eddy current sensors are used without problems can. Due to the significant deviation of the design of the transport cover 17 of a normal flat bar 14, it is not possible to use 17 left and right next to the transport cover 17 normal flat bars 14. At these positions, two intermediate lids 21 a, 21 b are provided. The intermediate covers close the gaps between the transport cover 17 and the adjacent flat bars 14, so that no fibers are blown out of the pressurized Kardierspalt at these locations.

Mit 22.ist ein Zahnriemen für den Transport der Deckelstäbe 14a bis 14n und des Transportdeckels 17 in Richtung B bezeichnet. Die Deckelstäbe 14a bis 14n bestehen aus Aluminiumstrangpress und weisen jeweils einen Hohlraum 14' auf.22. is a timing belt for the transport of the flat bars 14a to 14n and the transport cover 17 in the direction B designated. The flat bars 14a to 14n are made of extruded aluminum and each have a cavity 14 'on.

Der Transportstab 17 gemäß Fig. 3 als Träger der Elektronik und Energieversorgung, ist nicht an die Bauform eines Deckelstabes 14a bis 14n gebunden. Teil des Konzeptes ist es, alle benötigten Komponenten des Messdeckelsystems in einem Transportstab 17 unterzubringen. Der Transportstab 17 soll das Kardieren nicht stören, da hier aber keine Messungen vorgenommen werden, sind Abweichungen zum normalen Deckelstab 14a bis 14n möglich.The transport rod 17 according to Fig. 3 as a carrier of the electronics and power supply, is not bound to the design of a flat bar 14a to 14n. Part of the concept is to accommodate all required components of the Meßdeckelsystems in a transport rod 17. The transport rod 17 should not interfere with the carding, but since no measurements are made, deviations from the normal flat rod 14a to 14n are possible.

Die Grundform des Transportdeckels 17 umfasst ein Gehäuse 171 mit einem Innenhohlraum 172. Das Gehäuse 171 ist auf dem Deckelfuß 14" (Vollprofil) eines abgefrästen Deckelstabes 14a bis 14n angebracht. Die Abmaße des Profilinnenraums 172 ermöglichen die Aufnahme der erforderlichen Elektronikkomponenten. Der Transportdeckel 17 weist keine Kardierelemente auf, ersetzt jedoch drei Deckelstäbe 14a bis 14n. Unter Produktionsbedingung bedeutet dies, dass beim Einsatz in der Kardierzone an drei aufeinanderfolgenden Deckelstabplätzen keine Kardierarbeit geleistet wird. Aufgrund des herrschenden Überdrucks zwischen Tambour 4 und Deckelstäben 14a bis 14n sind zur Vermeidung des Ausblasens von Fasern die Zwischendeckel 21 a, 21 b (sh. Fig. 3) vorgesehen.The basic shape of the transport cover 17 includes a housing 17 1 with an internal cavity 17 second The housing 17 1 is mounted on the cover foot 14 "(full profile) of a milled flat bar 14a to 14n .The dimensions of the profile interior 17 2 enable the accommodation of the required electronic components The transport lid 17 has no carding elements, but replaces three flat bars 14a to 14n. Under production conditions, this means that no carding work is performed when used in the carding zone at three successive flat-bottomed spaces Due to the prevailing overpressure between spool 4 and flat bars 14a to 14n, the intermediate covers 21a, 21b (see FIG. Fig. 3 ) intended.

Im Innenhohlraum 172 des Gehäuses 171 ist entsprechend Fig. 4a, 4b ein Einlageblech 23 mit den verschiedenen Elektronikkomponenten besetzt. Jeder Wirbelstromsensor benötigt eine eigene Platine 24a, 24b bzw. 24c, hinzukommen die Systemelektronik 25, eine (nicht dargestellte) gemeinsame Elektronik der sechs Temperatursensoren, die Stromversorgung über einen Akkumulator 26 und ein Bluetooth Modul 27.In the inner cavity 17 2 of the housing 17 1 is corresponding Fig. 4a, 4b a liner 23 occupied with the various electronic components. Each eddy current sensor requires its own board 24a, 24b and 24c, added to the system electronics 25, a (not shown) common electronics of the six temperature sensors, the power supply via an accumulator 26 and a Bluetooth module 27th

Entsprechend Fig. 5 sind die beiden Zwischenstäbe 21a, 21b, links und rechts vom Transportdeckel 17, abgefräste Deckelstäbe 14a bis 14n. Zur Erhöhung der Steifigkeit ist vom Deckelstab jeweils ein Steg aus der rechten bzw. linken Seite stehen geblieben. Die Form der Zwischenstäbe 21a, 21b ergibt sich aus der Umlenkung des Transportdeckels im Deckelkreislauf.Corresponding Fig. 5 are the two intermediate rods 21a, 21b, left and right of the transport cover 17, milled flat bars 14a to 14n. To increase the rigidity of the flat bar in each case a bridge from the right or left side has stopped. The shape of the intermediate rods 21a, 21b results from the deflection of the transport cover in the lid circuit.

In den beiden Umkehrpunkten 13a, 13b des Deckelkreislaufs (sh. Fig. 1) benötigt der Transportdeckel 17 den Platz von drei Deckelstäben 14a bis 14n. Damit in der Kardierzone keine Fasern vor und hinter dem Transportdeckel 17 ausgeblasen werden, decken die beiden Zwischenstäbe 21a, 21b die Zwischenräume ab. Das abgefräste Profil mit jeweils einem Steg ist dabei der zulässige Bauraum, der von den Zwischenstäben 21a, 21b beansprucht werden kann.In the two reversal points 13a, 13b of the lid cycle (see FIG. Fig. 1 ), the transport cover 17 requires the space of three flat bars 14a to 14n. So that no fibers are blown out in front of and behind the transport cover 17 in the carding zone, the two intermediate rods 21a, 21b cover the intermediate spaces. The milled profile, each with a web is the allowable space that can be claimed by the intermediate rods 21a, 21b.

Der Transportdeckelstab 17 umfasst das Gehäuse 171 und den Deckelfuß 14".The transport cover rod 17 includes the housing 17 1 and the cover foot 14 ".

Das komplette Messsystem ist in Fig. 6 dargestellt. Es besteht aus dem Messdeckel 14d, dem Transportdeckel 17, den beiden Zwischendeckeln 21a, 21 b und einem Laptop 20 zur Anzeige und Auswertung der Messwerte.The complete measuring system is in Fig. 6 shown. It consists of the measuring cover 14d, the transport cover 17, the two intermediate covers 21a, 21b and a laptop 20 for displaying and evaluating the measured values.
