Description

Die vorliegende Erfindung betrifft ein Verfahren zum Betrieb einer Spinnereivorbereitungsmaschine, insbesondere Karde oder Krempel, mit dem ein Kardierabstand zwischen einer garnierten Walze und einem der Walze gegenüberliegenden Deckelstab mittels einer Steuerungseinheit eingestellt wird, weiterhin betrifft die Erfindung eine Vorrichtung einer Spinnereivorbereitungsmaschine zur Ausführung des Verfahrens.The present invention relates to a method for operating a spinning preparation machine, in particular a card or card, by means of which a carding distance between a garnished roller and a flat bar opposite the roller is set by means of a control unit. Furthermore, the invention relates to a device of a spinning preparation machine for carrying out the method.

Das Kardierergebnis beim Betrieb einer Karde ist unmittelbar abhängig vom Kardierabstand, welcher den Spalt zwischen der Walze und den Deckelstäben beschreibt. Folglich muss der Kardierabstand so eingestellt werden, dass ein gewünschtes Kardierergebnis erreicht wird. Sowohl der Deckelstab als auch die Walze können eine Garnitur aufweisen, wobei der Kardierabstand gemessen wird zwischen den Spitzen der Garnituren, und wobei die Größe des Kardierabstandes ein wesentlicher Maschinenparameter ist, welcher sowohl das Kardierergebnis als auch das Laufverhalten der Karde prägt. Insbesondere muss bei längerem Betrieb der Karde sichergestellt werden, dass sich die Spitzen der Garniturzähne nicht berühren. Insbesondere bei Wanderdeckelkarden befindet sich die Hauptkardierzone zwischen der Walze und dem Wanderdeckelaggregat, wobei insbesondere bei wandernden Deckelstäben beide garnierten Kardierpartner gegeneinander bewegt werden.The carding result when operating a card is directly dependent on the carding distance, which describes the gap between the roller and the flat bars. Consequently, the carding distance must be set so that a desired carding result is achieved. Both the flat bar and the roller can have a set, the carding distance being measured between the tips of the sets, and the size of the carding distance being an essential machine parameter which shapes both the carding result and the running behavior of the card. In particular, if the card is used for a long time, it must be ensured that the tips of the clothing teeth do not touch. In the case of revolving flat cards in particular, the main carding zone is located between the roller and the revolving flat aggregate, with both carding partners garnished being moved against one another, particularly in the case of moving flat bars.

In einer Spinnereivorbereitungsmaschine führt die geleistete Arbeit, insbesondere die Kardierarbeit einer Karde, zu einer Wärmeentwicklung, wodurch die Bauelemente der Maschine erwärmt werden. Diese Erwärmung führt zu Verlagerungen und Verformungen der Bauelemente. Um den Kardierabstand möglichst gleichmäßig zu halten, wird in der DE 10 2006 014 419 A1 vorgeschlagen, den Kardierabstand durch externe Energiezufuhr an mindestens eines der einander gegenüberliegenden Bauteile zu verkleinern oder zu vergrößern, wobei auch eine Drosselung der Energiezufuhr ermöglicht wird, sodass der Kardierabstand entsprechend eingestellt werden soll. Eine Messung von Temperaturgradienten innerhalb der Deckelstäbe ist jedoch nicht vorgesehen, sodass die entstehende Arbeitstemperatur der Walze und insbesondere der Deckelstäbe lediglich angenommen wird.In a spinning preparation machine, the work performed, in particular the carding work of a card, leads to heat development, as a result of which the components of the machine are heated. This heating leads to displacement and deformation of the components. In order to keep the carding distance as even as possible, the DE 10 2006 014 419 A1 proposed to reduce or enlarge the carding distance by external energy supply to at least one of the opposing components, wherein throttling of the energy supply is also made possible, so that the carding distance should be adjusted accordingly. A measurement of temperature gradients within the flat bars is not provided, however, so that the resulting working temperature of the roller and in particular of the flat bars is only assumed.

Eine Messung eines Abstandes zwischen einer Walze und einem Deckelstab einer Spinnereivorbereitungsmaschine beschreibt die DE 10 2009 031 979 A1 , wobei eine derartige Messung eines Abstandes mit Schwierigkeiten verbunden ist, insbesondere kann die Messung nicht während des Betriebs der Spinnereivorbereitungsmaschine erfolgen. Der Grund hierfür liegt darin, dass das zwischen der Walze und dem Deckelstab vorhandene Fasermaterial eine Abstandsmessung stört, verfälscht oder verhindert.A measurement of a distance between a roller and a flat bar of a spinning preparation machine describes the DE 10 2009 031 979 A1 Such a measurement of a distance is associated with difficulties, in particular the measurement cannot take place during the operation of the spinning preparation machine. The reason for this is that the fiber material between the roller and the flat bar interferes with, falsifies or prevents a distance measurement.

Die EP 0 801 158 B1 beschreibt eine Messung eines Abstandes zwischen einem Deckelstab und einer Walze mittels eines Laserstrahls, wobei eine derartige optische Messung auch wieder nur im Stillstand der Spinnereivorbereitungsmaschine möglich ist.The EP 0 801 158 B1 describes a measurement of a distance between a flat bar and a roller by means of a laser beam, such an optical measurement again being possible only when the spinning preparation machine is at a standstill.

In der DE 19923419 wird die Verwendung von einem oder mehrerer ortsfest angeordneten Sensoren beschrieben, mit denen der Abstand der Garniturspitzen des Deckelstabes zu den Sensoren bestimmt werden kann. Die Sensoren sind ausgebildet, die elektrische Kapazität zu messen.In the DE 19923419 describes the use of one or more stationary sensors with which the distance between the clothing tips of the flat bar and the sensors can be determined. The sensors are designed to measure the electrical capacitance.

Aufgabe der Erfindung ist die Weiterbildung eines Verfahrens zum Betrieb einer Spinnereivorbereitungsmaschine, insbesondere Karde oder Krempel, mit dem ein Kardierabstand möglichst während des Betriebs der Maschine bestimmt und über eine Steuerungseinheit eingestellt werden kann. Insbesondere ist es die Aufgabe der Erfindung, den konstruktiven Aufwand zum Bau der Vorrichtung zur Einstellung des Kardierabstandes gering zu halten.The object of the invention is the development of a method for operating a spinning preparation machine, in particular a card or card, with which a carding distance is determined as far as possible during the operation of the machine and is set via a control unit can. In particular, it is the object of the invention to keep the design effort for building the device for setting the carding distance low.

Diese Aufgabe wird ausgehend von einem Verfahren zum Betrieb einer Spinnereivorbereitungsmaschine gemäß dem Oberbegriff des Anspruches 1 und ausgehend von einer Vorrichtung zur Spinnereivorbereitung gemäß dem Oberbegriff des Anspruches 10 mit den jeweils kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved on the basis of a method for operating a spinning preparation machine according to the preamble of claim 1 and on the basis of a device for spinning preparation according to the preamble of claim 10 with the respective characteristic features. Advantageous developments of the invention are specified in the dependent claims.

Erfindungsgemäß sieht das Verfahren wenigstens die folgenden Schritte vor: Messen einer Temperatur an wenigstens einer Position am Deckelstab mittels eines im Deckelstab integrierten Temperatursensors; Übertragen der gemessenen Temperatur an die Steuerungseinheit; Bereitstellung eines Formänderungsmodells an die Steuerungseinheit umfassend eine Formänderungsinformation des Deckelstabes in Abhängigkeit der gemessenen Temperatur und Nachstellen des Kardierabstandes mittels der Steuerungseinheit.According to the invention, the method provides at least the following steps: measuring a temperature at at least one position on the flat bar by means of a temperature sensor integrated in the flat bar; Transmitting the measured temperature to the control unit; Provision of a shape change model to the control unit comprising information on the shape change of the flat rod as a function of the measured temperature and adjustment of the carding distance by means of the control unit.

Kerngedanke der Erfindung ist die Bereitstellung eines Formänderungsmodells, welches spezifisch für einen Deckelstab erstellt und an die Steuerungseinheit bereitgestellt wird, und das Formänderungsmodell beinhaltet wenigstens einen Zusammenhang zwischen einer Temperatur und einer sich mit der Temperatur ergebenden Formänderung des Deckelstabes. Die Temperatur im Deckelstab wird dabei an wenigstens einer Position gemessen, wobei insbesondere Temperaturprofile gemessen werden, und in Abhängigkeit der gemessenen Temperaturprofile kann basierend auf dem Formänderungsmodell eine Verformungsinformation abgeleitet werden, auf Basis derer die Steuerungseinheit den Kardierabstand zwischen dem Deckelstab und der Walze nachstellt. Das Formänderungsmodell ist dabei für jeden eingesetzten Deckelstab bereitzustellen, sofern beispielsweise eine Karde mit verschiedenen Deckelstäben betrieben werden kann, die insbesondere auch verschiedenartig garniert sein können.The core idea of the invention is to provide a shape change model which is created specifically for a flat bar and is made available to the control unit, and the shape change model includes at least one connection between a temperature and a shape change of the flat bar resulting with the temperature. The temperature in the flat rod is measured at at least one position, in particular temperature profiles being measured, and depending on the measured temperature profiles, deformation information can be derived based on the shape change model, on the basis of which the control unit determines the carding distance between the Flat rod and the roller adjusts. The shape change model is to be provided for each flat bar used, for example if a card can be operated with different flat bars, which in particular can also be garnished in different ways.

Der wenigstens eine Temperatursensor kann am Deckelstab angeordnet oder in diesem eingebracht bzw. integriert sein, wobei die integrierte Anordnung des Temperatursensors im oder am Deckelstab jede mögliche Position umfasst, mittels der an einer vorgegebenen Position am Deckelstab eine Temperaturinformation abgegriffen werden soll.The at least one temperature sensor can be arranged on the flat bar or can be introduced or integrated therein, the integrated arrangement of the temperature sensor in or on the flat bar comprising any possible position by means of which temperature information is to be tapped at a predetermined position on the flat bar.

Das Verfahren sieht weiterhin vor, dass wenigstens ein Deckelstab mit einem integrierten RFID-Tag bereitgestellt wird, der mit dem Temperatursensor gekoppelt oder mit diesem baueinheitlich ausgeführt ist. RFID-Tags können vorteilhaft und kostengünstig bereitgestellt und betrieben werden, insbesondere besteht die Möglichkeit, RFID-Tags ohne Energiequelle auszuführen, da ein Transpondersignal bereits eine hinreichende elektrische Energiemenge im RFID-Tag induzieren kann, um eine Temperaturinformation mit dem gekoppelten Temperatursensor auszulesen. Damit erfolgt die Übertragung der Temperaturinformation vom Temperatursensor an die Steuerungseinheit vorzugsweise drahtlos, beispielsweise über ein Transpondersignal oder Bluetooth.The method further provides that at least one flat rod with an integrated RFID tag is provided, which is coupled to the temperature sensor or is designed with the same construction. RFID tags can be provided and operated advantageously and inexpensively, in particular there is the possibility of executing RFID tags without an energy source, since a transponder signal can already induce a sufficient amount of electrical energy in the RFID tag in order to read out temperature information with the coupled temperature sensor. The temperature information is thus transmitted from the temperature sensor to the control unit preferably wirelessly, for example via a transponder signal or Bluetooth.

Zum Betrieb des Verfahrens ist es weiterhin von Vorteil, dass ein RFID-Lesegerät bereitgestellt wird, wobei die Übermittlung der gemessenen Temperatur mittels des integrierten RFID-Tags an das RFID-Lesegerät ausgeführt wird und wobei die Temperaturinformation mit dem RFID-Lesegerät an die Steuerungseinheit weitergeleitet wird. Sendet das RFID-Lesegerät zur Auslesung der Temperaturinformation ein Transpondersignal an den RFID-Tag, kann das Transpondersignal im RFID-Tag eine Spannung induzieren, die hinreichend ist, die Temperaturinformation auszulesen. Das RFID-Lesegerät kann dabei beispielsweise an der Wanderdeckeleinheit der Karde angeordnet sein, um eine möglichst kurze Übertragungsstecke zu schaffen. Selbstverständlich besteht auch die Möglichkeit einer drahtgebundenen Übertragung der Temperaturinformation an die Steuerungseinheit, beispielsweise über eine Kontaktiereinrichtung in der Wanderdeckeleinheit, die die Deckelstäbe durch die Wanderbewegung beispielsweise bei jedem Umlauf kontaktieren und so eine Temperaturinformation übertragen werden kann.To operate the method, it is also advantageous that an RFID reading device is provided, the temperature being transmitted to the RFID reading device by means of the integrated RFID tag, and the temperature information being forwarded to the control unit using the RFID reading device becomes. If the RFID reader sends a transponder signal to the RFID tag to read out the temperature information, the transponder signal can induce a voltage in the RFID tag that is sufficient to read out the temperature information. The RFID reader can For example, be arranged on the revolving cover unit of the card in order to create the shortest possible transmission path. Of course, there is also the possibility of a wired transmission of the temperature information to the control unit, for example via a contacting device in the revolving lid unit, which contacts the flat bars by the wandering movement, for example during each revolution, and thus temperature information can be transmitted.

Ein weiterer Vorteil wird erreicht, wenn das Formänderungsmodell in einem Speicher der Steuerungseinheit hinterlegt wird, wobei die Hinterlegung vor Inbetriebnahme der Spinnereivorbereitungsmaschine und/oder der verwendeten Deckelstäbe zugeordnet erfolgt. Es versteht sich von selbst, dass im Speicher der Steuerungseinheit auch mehrere Formänderungsmodelle hinterlegt werden können, und wird die Spinnereivorbereitungsmaschine mit bestimmten Deckelstäben zum Betrieb gerüstet, kann das den Deckelstäben zugeordnete Formänderungsmodell aus dem Speicher aktiviert bzw. in diesen eingelesen werden, und die Steuerungseinheit nimmt das Nachstellen des Kardierabstandes auf Basis des ausgewählten Formänderungsmodells vor.A further advantage is achieved if the shape change model is stored in a memory of the control unit, the storage taking place before the spinning preparation machine and / or the flat bars used are assigned. It goes without saying that several shape change models can also be stored in the memory of the control unit, and if the spinning preparation machine is equipped with certain flat bars for operation, the shape change model assigned to the flat bars can be activated from the memory or read into it, and the control unit takes readjusting the carding distance based on the selected shape change model.

Das Formänderungsmodell wird vor Inbetriebnahme der Spinnereivorbereitungsmaschine in den Speicher der Steuerungseinheit geladen. Die Bereitstellung des Formänderungsmodells kann auf verschiedene Weise erfolgen. Beispielsweise kann das Formänderungsmodell basierend auf mathematischen Beziehungen zwischen der Formänderung des Deckelstabes und einem Temperaturprofil im Deckelstab mit einem Berechnungsalgorithmus analytisch ermittelt und bereitgestellt werden. Auch Basis des Berechnungsalgorithmus kann insbesondere eine Durchbiegung des Deckelstabes ermittelt werden, wobei die Ermittlung in Abhängigkeit der Temperatur beispielsweise am Deckelfuß und am Deckelrücken erfolgt. Erwärmt sich der Deckelfuß beispielsweise stärker als der Deckelrücken, so erfolgt eine Durchbiegung des mittleren Abschnittes des Deckelstabes in Richtung zur Walze. Der Berechnungsalgorithmus umfasst dabei insbesondere den Wärmeausdehnungskoeffizienten des Materials des Deckelstabes, die Länge des Deckelstabes und eine Referenztemperatur, beispielsweise die Raumtemperatur. Da die Temperaturen bei einem erstellten Modell für einen entsprechenden Deckelstab die einzigen unbekannten Größen beim Kardieren sind, kann erfindungsgemäß mit der Erfassung der Temperatur mittels des wenigstens einen Temperatursensors das Formänderungsmodell gespeist bzw. erstellt werden, welches wie vorstehend beschrieben im Speicher der Steuerungseinheit abgelegt ist.The shape change model is loaded into the memory of the control unit before the spinning preparation machine is started up. The shape change model can be provided in various ways. For example, the shape change model can be analytically determined and provided based on mathematical relationships between the shape change of the flat bar and a temperature profile in the flat bar using a calculation algorithm. A deflection of the flat rod can also be determined in particular on the basis of the calculation algorithm, the determination depending on the Temperature takes place for example on the lid foot and on the lid back. If, for example, the cover foot heats up more than the back of the cover, the middle section of the cover rod bends in the direction of the roller. The calculation algorithm includes in particular the coefficient of thermal expansion of the material of the flat rod, the length of the flat rod and a reference temperature, for example the room temperature. Since the temperatures in a created model for a corresponding flat rod are the only unknown variables when carding, according to the invention, with the detection of the temperature by means of the at least one temperature sensor, the shape change model can be fed or created, which is stored in the memory of the control unit as described above.

Eine weitere Möglichkeit zur Bereitstellung des Formänderungsmodells umfasst ein Simulationsverfahren, welches computernummerisch durchgeführt wird, und mit dem verschiedene Temperaturszenarien durchgespielt werden. Wird ein Temperaturprofil des Deckelstabes im Betrieb der Spinnereivorbereitungsmaschine aufgenommen, kann basierend auf dem erstellten Formänderungsmodell insbesondere für den mittleren Bereich des Deckelfußes eine Durchbiegung ermittelt werden, die für das Nachstellen des Kardierabstandes zugrunde gelegt wird.A further possibility for providing the shape change model comprises a simulation process, which is carried out by computer number and with which various temperature scenarios are run through. If a temperature profile of the flat rod is recorded during operation of the spinning preparation machine, a deflection can be determined based on the shape change model created, in particular for the central region of the flat base, which is used as a basis for adjusting the carding distance.

Es versteht sich, dass das Formänderungsmodell auch experimentell ermittelt und bereitgestellt werden kann, indem mit wenigstens einem auf den Deckelstab aufgegebenen bekannten Temperaturprofil wenigstens eine Durchbiegung umfassende Formänderung des Deckelstabes ermittelt wird.It goes without saying that the shape change model can also be determined experimentally and made available by using at least one known temperature profile applied to the flat rod to determine at least one change in shape of the flat rod comprising deflection.

Für eine besonders vorteilhafte Ausführung des Verfahrens wird eine erste Temperaturinformation mit einem ersten Temperatursensor vom Deckelfuß abgegriffen und übertragen und eine zweite Temperaturinformation wird mit einem zweiten Temperatursensor vom Deckelrücken abgegriffen und übertragen. Insbesondere dann, wenn ein Temperaturunterschied zwischen dem Deckelfuß und dem Deckelrücken bekannt ist, kann eine Durchbiegung ermittelt werden. Dabei kann die Ermittlung in Bezug auf die Längserstreckung des Deckelstabes in der Mitte des Deckelstabes mit entsprechend angeordneten Temperatursensoren erfolgen, weiterhin kann die Erfassung der Temperatur an den Enden des Deckelstabes erfolgen, an denen auch Temperatursensoren angeordnet sein können. Insbesondere im Bereich der Mitte des Deckelstabes ist der Temperaturunterschied zwischen dem Deckelfuß und dem Deckelrücken wichtig für die Ermittlung der Durchbiegung.For a particularly advantageous embodiment of the method, a first temperature information is picked up and transmitted from the cover foot with a first temperature sensor and a second temperature information is transmitted Temperature information is picked up and transmitted from the back of the cover with a second temperature sensor. In particular, if a temperature difference between the lid foot and the lid back is known, a deflection can be determined. The determination with respect to the longitudinal extent of the flat bar in the middle of the flat bar can be carried out with appropriately arranged temperature sensors, and the temperature can also be recorded at the ends of the flat bar, at which temperature sensors can also be arranged. Especially in the area of the center of the flat rod, the temperature difference between the flat base and the back of the flat is important for determining the deflection.

Die Erfindung richtet sich weiterhin auf eine Vorrichtung zum Betrieb einer Spinnereivorbereitungsmaschine, insbesondere Karde oder Krempel, womit ein Kardierabstand zwischen einer garnierten Walze und einem der Walze gegenüberliegenden Deckelstab mittels einer Steuerungseinheit einstellbar ist. Erfindungsgemäß ist an die Steuerungseinheit ein Formänderungsmodell umfassend eine Formänderungsinformation des Deckelstabes in Abhängigkeit einer am Deckelstab messbaren Temperatur bereitgestellt, und wobei mit der Steuerungseinheit der Kardierabstand basierend auf dem Formänderungsmodell änderbar ist. Dabei ist der Kardierabstand über die Arbeitsbreite des Deckelstabes zur Trommel einstellbar, aber auch die Form des Deckelstabes (konkave oder konvexe Kontur der Garniturenfläche) über die Trommel einstellbar.The invention further relates to a device for operating a spinning preparation machine, in particular a card or card, with which a carding distance between a garnished roller and a flat bar opposite the roller can be set by means of a control unit. According to the invention, a shape change model comprising a change in shape information of the flat bar as a function of a temperature measurable on the flat bar is provided to the control unit, and the carding distance can be changed with the control unit based on the shape change model. The carding distance can be adjusted over the working width of the flat bar to the drum, but also the shape of the flat bar (concave or convex contour of the clothing surface) can be adjusted via the drum.

Die weiteren in Zusammenhang mit dem Verfahren beschriebenen Merkmale und die sich ergebenden Vorteile finden auch für die erfindungsgemäße Vorrichtung Berücksichtigung.The further features described in connection with the method and the resulting advantages are also taken into account for the device according to the invention.

Insbesondere weist wenigstens ein Deckelstab wenigstens einen Temperatursensor auf, mit dem die Temperatur an wenigstens einer Position am Deckelstab messbar ist, und wobei die gemessene Temperatur an die Steuerungseinheit übertragbar ist. Weiterhin ist es von Vorteil, wenn die Temperaturinformation vom Temperatursensor an die Steuerungseinheit drahtlos übertragbar ist. Hierfür kann der wenigstens eine Deckelstab wenigstens ein RFID-Tag aufweisen, der mit dem Temperatursensor gekoppelt ist oder der mit diesem integral ausgeführt ist.In particular, at least one flat rod has at least one temperature sensor with which the temperature on at least one Position on the flat rod is measurable, and the measured temperature can be transmitted to the control unit. It is also advantageous if the temperature information can be transmitted wirelessly from the temperature sensor to the control unit. For this purpose, the at least one flat bar can have at least one RFID tag which is coupled to the temperature sensor or which is embodied integrally with the latter.

Mit besonderem Vorteil ist ein erster Temperatursensor am Deckelfuß angeordnet, und ein zweiter Temperatursensor ist am Deckelrücken angeordnet, und es ist in Bezug auf die Längserstreckung des Deckelstabes insbesondere wenigstens ein Temperatursensor in der Mitte des Deckelstabes angeordnet und wenigstens ein Temperatursensor am Ende des Deckelstabes. Mit noch weiterem Vorteil ist wenigstens ein Temperatursensor am Deckelfuß in der Mitte des Deckelstabes angeordnet, weiterhin ist wenigstens ein Temperatursensor am Deckelrücken in der Mitte des Deckelstabes angeordnet, wobei ein Temperatursensor an jedem der beiden äußeren Enden des Deckelstabes angeordnet ist, gegebenenfalls hier auch jeweils am Deckelfuß und am Deckelrücken. Mit den sich ergebenden wenigstens vier bzw. sechs Temperatursensoren werden entsprechende Temperaturinformationen an die Steuerungseinheit übermittelt und in Korrelation mit dem Formänderungsmodell gebracht bzw. in diesem appliziert, worauf basierend eine Formänderungsinformation abgeleitet und an die Maschinensteuerung gegeben wird, sodass eine Nachstellung des Kardierabstandes mittels der Steuerungseinheit erfolgen kann. Hierfür kann für die Aufnahme der Deckelstäbe ein entsprechender Aktuator vorgesehen sein.It is particularly advantageous if a first temperature sensor is arranged on the lid base, and a second temperature sensor is arranged on the back of the lid, and in relation to the longitudinal extension of the flat rod, in particular at least one temperature sensor is arranged in the middle of the flat rod and at least one temperature sensor at the end of the flat rod. With a further advantage, at least one temperature sensor is arranged on the base of the cover in the middle of the cover rod, furthermore at least one temperature sensor is arranged on the back of the cover in the center of the cover rod, a temperature sensor being arranged on each of the two outer ends of the cover rod, if appropriate also here in each case Lid foot and on the lid back. With the resulting at least four or six temperature sensors, corresponding temperature information is transmitted to the control unit and correlated with or applied in the shape change model, whereupon a shape change information is derived and passed on to the machine control system, so that the carding distance is adjusted by means of the control unit can be done. For this purpose, a corresponding actuator can be provided for receiving the flat bars.

Die Drehrichtungen der Walzen sind mit gebogenen Pfeilen gezeigt. Der Mittelpunkt der Walze 10 ist mit M bezeichnet. Die Position 31 gibt die Garnitur der Walze 10 wieder, und mit 32 ist die Drehrichtung der Walze 10 bezeichnet. Mit dem Pfeil B ist die Bewegungsrichtung des Wanderdeckels 27 in Kardierstellung und mit dem Pfeil C die Rücktransportrichtung der Deckelstäbe 11 dargestellt. Mit den Bezugszeichen 33 sind Funktionselemente bezeichnet, die in Verbindung mit der Walze 10 stehen. Der Pfeil A bezeichnet die Arbeitsrichtung. Figure 1 shows a card 100 with a feed roller 18, a dining table 19, licker-in 20, a roller 10, a doffer 21, a doctor roller 22, squeeze rollers 23, a fleece guide element 24, a pile funnel 25, take-off rollers 26, the revolving cover 27 with cover deflection rollers 28 and garnished cover rods 11, a can 29 and a can stick 30. The directions of rotation of the rollers are shown with curved arrows. The center of the roller 10 is designated by M. The position 31 represents the clothing of the roller 10, and 32 denotes the direction of rotation of the roller 10. The arrow B shows the direction of movement of the revolving cover 27 in the carding position and the arrow C shows the return direction of the flat bars 11. The reference numbers 33 denote functional elements which are connected to the roller 10. The arrow A indicates the direction of work.

Der Wanderdeckel 27 mit den umlaufenden Deckelstäben 11 kann mit Bezug auf den Mittelpunkt M der Walze 10 im Abstand verändert werden, sodass sich auch der Kardierabstand zwischen der Garnitur 31 der Walze 10 und den ebenfalls garnierten Deckelstäben 11 verändert.The revolving cover 27 with the circumferential flat bars 11 can be changed in distance with respect to the center M of the roller 10, so that the carding distance between the clothing 31 of the roller 10 and the likewise decorated flat bars 11 changes.

Figur 2 zeigt mehrere Deckelstäbe 11 nebeneinander, die gemeinsam an einem Zahnriemen 34 aufgenommen sind und gemäß Figur 1 im oder am Wanderdeckel 27 in Arbeitsrichtung A umlaufen können. Beispielhaft ist an einem Deckelstab 11 ein Temperatursensor 13 im Bereich des Deckelfußes 42 angeordnet, ein weiterer Temperatursensor 13 ist im Bereich des Deckelrückens 43 angeordnet. An einem weiteren Deckelstab 11 ist ein RFID-Tag 15 angeordnet, der mit einer weiteren nicht dargestellten Anordnung von Temperatursensoren eine Einheit bilden kann, mit der ein Temperaturmesswert ermittelt und als Temperaturinformation über eine RFID-Übertragungsstrecke an ein RFID-Lesegerät 16 übermittelt werden kann, das schematisch dargestellt ist. Der Deckelstab 11 mit dem fußseitigen und dem rückenseitigen Temperatursensor 13 ist in der folgenden Figur 3 in einer Seitenansicht dargestellt. Figure 2 shows several flat bars 11 side by side, which are received together on a toothed belt 34 and according to Figure 1 can circulate in or on the revolving cover 27 in the working direction A. For example, a temperature sensor 13 is arranged on a flat bar 11 in the area of the lid base 42, a further temperature sensor 13 is located in the area of the lid back 43. An RFID tag 15 is arranged on a further flat rod 11, which can form a unit with a further arrangement of temperature sensors, not shown, with which a temperature measurement value can be determined and transmitted as temperature information to an RFID reader 16 via an RFID transmission link, which is shown schematically. The flat bar 11 with the foot-side and the back-side temperature sensor 13 is as follows Figure 3 shown in a side view.

Figur 3 zeigt einen Deckelstab 11 unter Erwärmung, welche mit einer Zufuhr von Wärme Qpunkt wiedergegeben ist. Durch die Erwärmung des Deckelstabes 11, die überwiegend am Deckelfuß 42 erfolgt, an der auch die Deckelgarnitur 35 angeordnet ist, erfolgt eine Durchbiegung des Deckelstabes 11 in Richtung zur Wärmequelle und damit in Richtung zur Walze gemäß Figur 1, sodass sich eine Biegelinie 36 durch den Deckelstab 11 hindurch ergibt, woraus folgend ein Krümmungsradius R entsteht. Die unterseitig des Deckelstabes 11 angeordnete nicht dargestellte Walze 10 im eingebauten Zustand in der Karde 100 weist zu dem Deckelstab 11 folglich im Bereich der Mitte einen kleineren Abstand auf als im Bereich der Enden des Deckelstabes 11. Durch die höhere Temperatur T1 im Bereich des Deckelfußes 42 relativ zur Temperatur T2 am Deckelrücken 43 ergibt sich ein Temperaturunterschied, der zu der vorstehend beschriebenen Biegelinie 36 führt. Figure 3 shows a flat rod 11 with heating, which is shown with a supply of heat Qpunkt. The heating of the flat bar 11, which takes place predominantly on the flat foot 42, on which the flat clothing 35 is also arranged, causes the flat bar 11 to bend in the direction of the heat source and thus in the direction of the roller Figure 1 , so that there is a bending line 36 through the flat rod 11, which results in a radius of curvature R. The roller 10, not shown, arranged on the underside of the flat bar 11 in the installed state in the card 100 consequently has a smaller distance from the flat bar 11 in the region of the center than in the area of the ends of the flat bar 11. The higher temperature T1 in the area of the lid base 42 relative to the temperature T2 on the lid back 43 results in a temperature difference which leads to the bending line 36 described above.

Figur 4 stellt in schematischer Weise die Vorrichtung zum Betrieb einer Spinnereivorbereitungsmaschine dar, mit der ein Kardierabstand zwischen einem Deckelstab 11 und einer Walze 10 nachgestellt werden kann. Die Nachstellung erfolgt mittels eines Aktuators 37, mit dem die Führungseinrichtung 38 zur Führung der Deckelstäbe 11 im Wanderdeckel gemäß dem Doppelpfeil hoch und runter gefahren werden kann. Figure 4 schematically illustrates the device for operating a spinning preparation machine, with which a carding distance between a flat bar 11 and a roller 10 can be adjusted. The adjustment is carried out by means of an actuator 37 with which the guide device 38 for guiding the flat bars 11 in the revolving lid can be moved up and down in accordance with the double arrow.

Im Deckelfuß 42 des Deckelstabes 11 ist ein erster Temperatursensor 13 angeordnet, und im Deckelrücken 43 ist ein zweiter Temperatursensor 13 angeordnet. Weiterhin ist im Deckelfuß 42 ein RFID-Tag 15 schematisch dargestellt, welcher eine Temperaturinformation über eine drahtlose Übertragungsstrecke 39 an ein RFID-Lesegerät 16 übermittelt, und das RFID-Lesegerät 16 übermittelt die Temperaturinformation an die Steuerungseinheit 12. Erfindungsgemäß ist die Steuerungseinheit 12 mit einem Speicher 17 ausgeführt, welcher ein Formänderungsmodell 14 umfasst. Zum Betrieb des Verfahrens wird das Formänderungsmodell 14 aus dem Speicher 17 über eine Ausleseverbindung 40 vom Speicher 17 an die Steuerungseinheit 12 übermittelt, und das Formänderungsmodell 14 umfasst eine Formänderungsinformation des Deckelstabes 11 in Abhängigkeit der gemessenen Temperaturen, die mit den Temperatursensoren 13 gemessen wurden. Insbesondere die gemessenen Temperaturen zwischen dem oberen Temperatursensor 13 im Deckelrücken 43 und dem unteren Temperatursensor 13 im Deckelfuß 42 ergeben ein Wertepaar der Temperaturen T1 und T2 mit T1 > T2, auf Basis dessen mit dem Formänderungsmodell 14 durch die Steuerungseinheit 12 eine Nachstellinformation generiert werden kann, sodass über eine Steuerstrecke 41 der Aktuator 37 mit der Steuerungseinheit 12 angesteuert werden kann.A first temperature sensor 13 is arranged in the lid foot 42 of the flat bar 11, and a second temperature sensor 13 is arranged in the lid back 43. Furthermore, an RFID tag 15 is schematically shown in the cover foot 42, which transmits temperature information to an RFID reader 16 via a wireless transmission link 39, and the RFID reader 16 transmits the temperature information to the control unit 12. According to the invention, the control unit 12 is equipped with a Executed memory 17, which comprises a shape change model 14. To operate the method, the shape change model 14 is transmitted from the memory 17 to the control unit 12 via a read-out connection 40 from the memory 17, and the shape change model 14 comprises shape change information of the flat rod 11 as a function of the measured temperatures, which were measured with the temperature sensors 13. In particular, the measured temperatures between the upper temperature sensor 13 in the lid back 43 and the lower temperature sensor 13 in the lid foot 42 result in a value pair of the temperatures T1 and T2 with T1> T2, on the basis of which an adjustment information can be generated by the control unit 12 using the shape change model 14, so that the actuator 37 can be controlled with the control unit 12 via a control path 41.

Die Nachstellung des Kardierabstandes und damit die Höheneinstellung der Führungseinrichtung 38 kann dabei im laufenden Betrieb der Spinnereivorbereitungsmaschine erfolgen, sodass nicht nur zu einem diskreten Zeitpunkt die Nachstellung erfolgt, sondern diese kann über den gesamten Betriebszeitraum der Spinnereivorbereitungsmaschine kontinuierlich betrieben werden. Das im Speicher 17 vorhandene Formänderungsmodell 14 ist dabei spezifisch ausgerichtet auf den Deckelstab 11 mit Bezug auf das Material, die Geometrie und die Größe, und jeder eingesetzte Deckelstab 11 benötigt ein eigenes Formänderungsmodell 14, sofern Unterschiede zwischen verschiedenen Deckelsätzen mit den Deckelstäben 11 vorherrschen. Jedoch kann es hinreichend sein, innerhalb eines Deckelstabsatzes mit einer Vielzahl von zueinander gleichen Deckelstäben 11 nur einzelne Deckelstäbe 11 mit den Temperatursensoren 13 und dem RFID-Tag 15 auszustatten, da angenommen werden kann, dass sich in den gemeinsam betriebenen Deckelstäben 11 ein zueinander jeweils gleiches Temperaturprofil einstellt.The adjustment of the carding distance and thus the height adjustment of the guide device 38 can take place while the spinning preparation machine is in operation, so that the adjustment not only takes place at a discrete point in time, but can be operated continuously over the entire operating period of the spinning preparation machine. The shape change model 14 present in the memory 17 is specifically oriented to the flat bar 11 with respect to the material, the geometry and the size, and each flat bar 11 used requires its own shape change model 14 if there are differences between different sets of lid with the flat bars 11. However, it may be sufficient to equip only individual flat rods 11 with the temperature sensors 13 and the RFID tag 15 within a flat rod set with a plurality of flat rods 11 that are identical to one another, since it can be assumed that the flat rods 11 that are operated together are the same as each other Temperature profile.

Die Erfindung beschränkt sich in ihrer Ausführung nicht auf das vorstehend angegebene bevorzugte Ausführungsbeispiel. Vielmehr ist eine Anzahl von Varianten denkbar, welche von der dargestellten Lösung auch bei grundsätzlich anders gearteten Ausführungen Gebrauch macht. Sämtliche aus den Ansprüchen, der Beschreibung oder den Zeichnungen hervorgehenden Merkmale und/oder Vorteile, einschließlich konstruktiver Einzelheiten oder räumlicher Anordnungen, können sowohl für sich als auch in den verschiedensten Kombinationen erfindungswesentlich sein.The embodiment of the invention is not limited to the preferred exemplary embodiment specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different types. All of the features and / or advantages arising from the claims, the description or the drawings, including structural details or spatial arrangements, can be essential to the invention both individually and in the most varied of combinations.
