Abstract

A process for the control of napped warp let-off entails holding the warp tension profile constant. Here the required consumption of napped warp yarn is determined from pre-held values on the basis of pattern data and used to modulate the extent of positional control. Also claimed is a terry loom for implementation of the process whereby the loom has a napped warp beam let-off device and a swivelling nap roller which are coupled together via a regulator to maintain the warp tension constant. Here there is a controller in which the pattern data are stored and which is connected by the transfer of signals to the regulator device (11) to modulate the regulating device. <IMAGE>

Das Frottierweben erfolgt bekanntlich mit einer straffen Grundkette und einer lockeren Florkette, wobei die Kettspannungen durch Koordination der Bewegungsabläufe der Kettablasseinrichtung 1 und der Warenabzugseinrichtung 2 und einem Kettspannungssystem 3, bei der Grundkette bzw. durch die Koordination des Bewegungsablaufes der Florkettablasseinrichtung 4 und einer Florpendelwalze 5 für die Florkette erzeugt werden.As is known, terry weaving is carried out with a taut base chain and a loose pile chain, the warp tensions being achieved by coordinating the movement sequences of the warp let-off device 1 and the take-off device 2 and a warp tensioning system 3, in the case of the base chain or by coordinating the movement sequence of the pile warp let-off device 4 and a pile pendulum roller 5 for the pile chain are generated.

Das Frottierweben erfolgt anhand von frei programmierbaren Musterdaten, welche die Bindung, Farbe, Funktionen, Schussdichte, Maschinendrehzahl, Schussfadenspannung, Kettfadenspannung und Florhöhe betreffen und in der Jacquard-Einrichtung 7 oder der Steuereinrichtung 9 abgelegt werden.

It is pointed out that the method can also be applied to weaving machines that weave according to the principle of fabric control.

Beim Frottierweben wird zur Bildung der Schlinge jeweils eine bestimmte Länge des Florkettfadens benötigt, die von der Florkettablasseinrichtung abgewickelt wird.In terry weaving, a specific length of the pile warp thread is required to form the loop, which is unwound by the pile warp let-off device.

Hierzu kann eine in Fig. 1 dargestellte Ausführungsform einer Frottierwebmaschine verwendet werden. Zu den bereits genannten Einrichtungen enthält diese Webmaschine eine Fachbildevorrichtung mit einer Schafteinrichtung 6 oder Jacquard-Einrichtung 7 sowie eine Webladensteuereinrichtung 8. Diese Einrichtungen werden mittels einer Steuereinrichtung 9 gesteuert. Die Steuereinrichtung 9 oder die Jacquard-Einrichtung 7 enthält ein Steuermittel 10, in welchem die Musterdaten binär und/oder numerisch abgelegt sind. Die Steuereinrichtung 9 enthält ferner eine Regeleinrichtung 11 für den Bewegungsablauf des Florkettablasses und eine Steuereinheit 12 mit Tastatur zur Beeinflussung der Steuerung der Webmaschine. Auf die Steuerung der Webmaschine wird in der nachfolgenden Beschreibung nur insoweit eingegangen, wie es für das Verständnis des hier in Rede stehenden Verfahrens erforderlich ist.An embodiment of a terry weaving machine shown in FIG. 1 can be used for this. To the already This weaving machine contains a shedding device with a shaft device 6 or jacquard device 7 and a weaving shop control device 8. These devices are controlled by means of a control device 9. The control device 9 or the jacquard device 7 contains a control means 10 in which the pattern data are stored in binary and / or numerical form. The control device 9 also contains a control device 11 for the movement sequence of the pile warp let-off and a control unit 12 with a keyboard for influencing the control of the weaving machine. The control of the weaving machine is only dealt with in the following description insofar as is necessary for understanding the method in question.

Die in Fig. 2 dargestellte Regelvorrichtung enthält einen Sensor 21, der im Bereich der Florpendelwalze 5 angeordnet ist, einen Sensor 22, der die Drehzahl der Florkettablasseinrichtung 4 misst, eine Einrichtung 23, um die Drehzahl der Florkettablasseinrichtung einzustellen und eine Messanordnung 14, um die abgezogene Florkettfadenlänge festzustellen. Ferner enthält die Regelvorrichtung eine Anordnung bestehend aus einem ersten Regler 26 mit einem ersten Eingang 27, der mit dem Sensor 21 elektrisch verbunden ist, mit einem zweiten Eingang 28, der mit einem Sollwertgeber verbunden ist und mit einem Ausgang 29, einen zweiten Regler 30 mit einem ersten Eingang 31, der mit dem Ausgang 29 des ersten Reglers 26 verbunden ist, einem zweiten Eingang 32, der mit der Steuereinrichtung 9 verbunden ist und mit einem Ausgang 34 sowie einen dritten Regler 35 mit einem ersten Eingang 36, der mit dem Ausgang 34 des zweiten Reglers 30 verbunden ist, einem zweiten Eingang 37, der mit dem Drehzahlgeber 22 verbunden ist und einem Ausgang 38, der mit der Drehzahleinstelleinrichtung 23 verbunden ist.The control device shown in FIG. 2 contains a sensor 21 which is arranged in the region of the pile pendulum roller 5, a sensor 22 which measures the speed of the pile warp let-off device 4, a device 23 for adjusting the speed of the pile warp let-off device and a measuring arrangement 14 for measuring the deducted length of pile warp thread. Furthermore, the control device contains an arrangement consisting of a first controller 26 with a first input 27, which is electrically connected to the sensor 21, with a second input 28, which is connected to a setpoint generator, and with an output 29, a second controller 30 with a first input 31, which is connected to the output 29 of the first controller 26, a second input 32, which is connected to the control device 9 and an output 34, and a third controller 35 with a first input 36, which is connected to the output 34 of the second controller 30 is connected, a second input 37 which is connected to the speed sensor 22 and an output 38 which is connected to the speed setting device 23.

Zum Frottierweben sind eine Grundkette 4, deren Kettspannungsverlauf durch die Koordination der Bewegungsabläufe einer Kettablasseinrichtung mit elektronisch gesteuertem Antrieb und einer Warenabzugvorrichtung mit einem elektronisch gesteuerten Antrieb konstant gehalten wird und eine Florkette benötigt, deren Kettspannung durch einen Regelkreis 11, eine Florpendelwalze 5 als Istwertgeber und einen elektronisch gesteuerten Antrieb der Florkettablasseinrichtung als Stellglied konstant gehalten wird. Der Florkettfadenverbrauch wird in erster Linie durch die Musterdaten 41 für die Florhöhe bestimmt. Deshalb wird das hier in Rede stehende Verfahren ausgehend von den Musterdaten Florhöhe beschrieben, die als Sollwert für die Regelung verwendet wird.For terry weaving there is a basic chain 4, the warp tension curve of which is kept constant by coordinating the movement sequences of a warp let-off device with an electronically controlled drive and a goods take-off device with an electronically controlled drive and requires a pile chain, the warp tension of which is controlled by a control circuit 11, a pile pendulum roller 5 as an actual value generator and one electronically controlled drive of the pile warp let-off device is kept constant as an actuator. The pile warp thread consumption is primarily determined by the pattern data 41 for the pile height. Therefore, the method in question is described on the basis of the pattern data pile height, which is used as the setpoint for the control.

In einem ersten Schritt 42 wird der Sollwert der Florhöhe in eine Beziehung zu den für die Florbildung erforderlichen Anschlagdistanzen gesetzt, die für die Frottierart notwendig sind. Dadurch wird eine Soll-Florlänge für jeden Schuss bestimmt. Diese Bestimmung erfolgt mit einem Vorhalt, d.h. zu einem Zeitpunkt, der eine beliebige Anzahl von Schüssen z.B. fünf Schüsse vor dem tatsächlichen Eintrag des betreffenden Schusses erfolgt. Der Vorhalt ist frei wählbar.In a first step 42, the desired value of the pile height is related to the stop distances required for the pile formation, which are necessary for the type of terry. This determines a target pile length for each shot. This determination is made with a lead, i.e. at a time that any number of shots e.g. five shots before the actual entry of the shot in question. The lead is freely selectable.

Aufgrund des dynamischen Verhaltens der Florbildungsorgane sowie der webtechnisch bedingten Umständen (Garnbeschaffenheit, Bindung usw.), manifestiert sich eine veränderte Kettspannung der Florkette. In einem gleichzeitig durchgeführten zweiten Schritt 43 wird dieser Unterschied mit Hilfe eines Parameters ausgeglichen, in dem der Wert des Parameters in einem bestimmten Verhältnis mit der Soll-Florlänge Schuss um Schuss verrechnet wird.Due to the dynamic behavior of the pile formation organs as well as the weaving-related circumstances (yarn quality, binding etc.), a changed warp tension of the pile chain manifests itself. In a second step 43 carried out at the same time, this difference is compensated for with the aid of a parameter in which the value of the parameter is offset in a certain ratio with the desired pile length shot by shot.

Aus diesen zwei Schritten wird eine Vorgabe/Vorgabewert für die zur Bildung der Schlinge erforderlichen Kettfadenlänge ermittelt.From these two steps, a default value is determined for the warp thread length required to form the loop.

Zusätzlich zur schnelleren Regeloptimierung oder auch anstelle des zweiten Schrittes 43 wird ein Schritt 44 durchgeführt, bei welchem die Länge der vom Florkettbaum abgewickelten Florkettfadens gemessen wird. Eine Abweichung zwischen Soll-Florlänge und Ist-Florlänge wird entweder im Parameter von Schritt 43 berücksichtigt oder mittels zusätzlichen Parameter Längenmessung in den Wert der Soll-Florlänge einbezogen.In addition to the faster rule optimization or instead of the second step 43, a step 44 is carried out in which the length of the pile warp thread unwound from the pile warp beam is measured. A deviation between the desired pile length and the actual pile length is either taken into account in the parameter of step 43 or is included in the value of the desired pile length by means of additional parameter length measurement.

Die in den zwei resp. drei Schritten ermittelte Vorgabe wird wie nachfolgend in die Regelung einbezogen.The in the two resp. The three-step default is included in the rule as follows.

Durch einen Soll/Ist-Vergleich wird durch den ersten Regler 26 eine die Position der Florpendelwalze 5 bzw. die Kettspannung der Florkette darstellende Stellgrösse, welche die Grunddrehzahl der Florkettablasseinrichtung zur Aufrechterhaltung der Florkettspannung darstellt erzeugt und an den ersten Eingang des zweiten Reglers 30 angelegt. Die mit Vorhalt bestimmte Vorgabe für die zu webende Schlinge wird als zweiter Eingang des zweiten Reglers 30 einbezogen, so dass dessen Stellgrösse die Drehzahl der Kettablasseinrichtung bei der Bereitstellung der zur Bildung der Schlinge erforderlichen Florkettfadenlänge darstellt. Diese Stellgrösse bildet eine Führungsgrösse für den dritten Regler 35, der durch einen Soll/Ist-Vergleich, die durch die Führungsgrösse vorgegebene Drehzahl regelt.By means of a target / actual comparison, the first controller 26 generates an actuating variable which represents the position of the pile pendulum roller 5 or the warp tension of the pile chain and which represents the basic speed of the pile warp let-off device for maintaining the pile warp tension and applies it to the first input of the second controller 30. The specification for the loop to be woven, which is determined with lead, is included as the second input of the second controller 30, so that its manipulated variable represents the speed of the warp let-off device when the pile warp thread length required to form the loop is provided. This manipulated variable forms a reference variable for the third controller 35, which controls the speed specified by the reference variable by means of a target / actual comparison.

Wie bereits erwähnt erfolgt das Frottierweben anhand von frei programmierbaren Musterdaten. Die Musterdaten können mit Hilfe der Steuereinheit abgelegt und verändert werden, um den Verfahrensablauf und folglich das Frottierweben zu optimieren.As already mentioned, terry weaving is based on freely programmable pattern data. With the help of the control unit, the sample data can be stored and changed in order to optimize the process sequence and consequently terry weaving.

Die nach der sogenannten Musterung definitiv abgelegten Musterdaten bilden die Grundlage für die Herstellung eines Gewebes. Die Musterdaten werden in der Steuereinrichtung abgelegt und müssen im Regelfall entsprechend den verwendeten Kettfäden, Florkettfäden und Schussfäden verändert werden, um optimale Herstellungsbedingungen zu schaffen. Diese Aenderungen werden mit Hilfe verschiedener, einzelner Parameter vorgenommen. Die Anwendung der Parameter und deren Auswirkung wird z.B. für die Gewebeanforderung Tuchgewicht erläutert.The pattern data definitely stored after the so-called patterning form the basis for the production of a fabric. The sample data are stored in the control device and generally have to be changed in accordance with the warp threads, pile warp threads and weft threads used in order to create optimal production conditions. These changes are made using various individual parameters. The application of the parameters and their impact is e.g. explained for the fabric requirement fabric weight.

Für eine Gewichtsbestimmung sind hauptsächlich die Anteile von Grundkette, Schussfäden und Florkette zu berücksichtigen. Eine Gewichtsänderung ist am einfachsten mit der Florketteinarbeitung zu erreichen und zwar durch Aenderung der Schlingenhöhe.Mainly the proportions of the base warp, weft threads and pile warp are to be considered for a weight determination. The easiest way to change the weight is to incorporate the pile chain by changing the loop height.

Die nachfolgende Beschreibung bezieht sich auf 3-Schuss-Frottierware, wobei jede Schussgruppe einen ersten und zweiten Teilanschlag und einen Vollanschlag umfasst. Im vorliegenden Fall wird nur der dritte Schuss an den Warenrand angeschlagen. Dadurch werden Vorschlaggruppen gebildet, die der gewünschten Schlingenhöhe entsprechend vom Warenrand entfernt angeordnet werden. Hierzu wird der erste und zweite Schuss jeweils durch einen Teilanschlag bezüglich dem Warenrand auf eine Distanz vorgeschoben, die als Vorschlagdistanz bezeichnet wird.The following description refers to 3-weft terry goods, with each weft group comprising a first and second partial stop and a full stop. In the present case, only the third shot is struck on the edge of the goods. This creates suggestion groups that are arranged according to the desired loop height away from the goods edge. For this purpose, the first and second shot are each advanced through a partial stop with respect to the edge of the goods at a distance which is referred to as the suggested distance.

Bei dem hier in Rede stehenden Verfahren kann diese Vorschlagsdistanz entweder durch manuelle Eingabe mittels der Tastatur 12 (Fig. 1) oder durch die Musterdaten vorgegeben werden, die entweder in der Fachbildevorrichtung und/oder Steuereinrichtung abgelegt und in letzterer aufgrund von vorbestimmten Artikelangaben errechnet werden. Die nach diesen Angaben berechnete Frottierware hat ein entsprechendes theoretisches Tuchgewicht. Um Frottierware mit einem vorgegebenen Tuchgewicht herzustellen, werden bei dem erfindungsgemässen Verfahren Parameter angewendet, um die Vorschlagdistanz zu ändern und der daraus folgenden Aenderung der Schlingenhöhe das Tuchgewicht anzupassen.In the method in question, this suggested distance can be specified either by manual entry using the keyboard 12 (FIG. 1) or by the sample data, which are either stored in the shedding device and / or control device and are calculated in the latter on the basis of predetermined article information. The terry goods calculated according to this information have a corresponding theoretical Cloth weight. In order to produce terry goods with a predetermined cloth weight, parameters are used in the method according to the invention in order to change the suggested distance and to adapt the cloth weight to the consequent change in the loop height.

Hierzu werden zwei Wege beschritten. Zum einen wird die Vorschlagsdistanz für sämtliche Teilschüsse durch den Parameterwert korrigiert und zum anderen wird die Vorschlagdistanz für den ersten Vorschlagschuss entsprechend einem Parameter reduziert. Mit dem zweiten Weg kann in besonders vorteilhafter Weise das Schlingenbild beeinflusst werden.There are two ways to do this. On the one hand, the proposed distance for all partial shots is corrected by the parameter value, and on the other hand, the proposed distance for the first proposed shot is reduced according to a parameter. With the second way, the loop pattern can be influenced in a particularly advantageous manner.

Ein weiteres Merkmal der Erfindung ist, dass auf die Frottierart ein Einfluss ausgeübt werden kann, in dem die in den Musterdaten abgelegte Frottierart entweder geändert oder wahlweise festgelegt wird.Another feature of the invention is that an influence can be exerted on the type of terry in which the type of terry stored in the sample data is either changed or optionally set.

Bei dem Verfahren wird der Bewegungsablauf des Kettablasses geregelt, in dem der Florkettfadenverbrauch mit Vorhalt aufgrund von Musterdaten bestimmt und zur Modulation der Stellgrösse einer Regelung verwendet wird, wobei die Musterdaten frei programmierbar sind.In the method, the sequence of movements of the warp let-down is regulated by determining the pile warp thread consumption with lead based on pattern data and using it to modulate the manipulated variable of a regulation, the pattern data being freely programmable.

Eine Webmaschine ist hierzu mit einer Steuereinrichtung 9 versehen, die mit der Regeleinrichtung 11 signalübertragend verbunden ist, um die Stellgrösse zu modulieren. Dadurch kann das Tuchgewicht des Gewebes eingehalten und/oder geändert werden.For this purpose, a weaving machine is provided with a control device 9, which is connected to the control device 11 in a signal-transmitting manner in order to modulate the manipulated variable. As a result, the weight of the fabric can be maintained and / or changed.
