Description

Die Erfindung betrifft eine Schärmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a warping machine according to the Preamble of claim 1.

Eine solche Schärmaschine ist aus DE 91 10 393 U bekannt. Dort sind Schärriet und Auftragsdicken-Meßeinrichtung gemeinsam am Schärschlitten angebracht. Der Schärschlitten ist parallel zur Trommelachse und quer hierzu verschiebbar. Hierbei treten Schwierigkeiten auf, weil Fadenzufuhr und Messung praktisch an der selben Stelle erfolgen. So benötigt man eine Umlenkwalze und muß beengte Platzverhältnisse in Kauf nehmen.Such a warping machine is known from DE 91 10 393 U. There are Schärriet and application thickness measuring device attached to the warping slide together. The Skiving carriage is parallel to the drum axis and across movable for this. Difficulties arise here on because thread feed and measurement are practically the same Place. So you need a deflection roller and has to accept limited space.

Ein Verfahren zum Schären von Fäden auf eine Schärtrommel einer Schärmaschine ist aus der D2-OS 37 02 293 bekannt. Bei diesem Verfahren wird ein Schärriet in Abhängigkeit von der anwachsenden Wickeldicke relativ zur Schärtrommel verschoben, indem beim Schären des ersten Bandes mit vorgegebenem Schärschlittenvorschub der Wikkelumfang von einem Tastorgan bei Stillstand der Schärtrommel abgetastet und dabei dessen Verstellweg während einer Meßwickelphase in Abhängigkeit von der Anzahl der Umdrehungen der Schärtrommel gemessen wird. Danach wird beim Schären des Restes des ersten Schärbandes und nach dem Kopieren des Meßwickels beim Schären der Folgebänder der Vorschub des Schärschlittens beim Schären des Restes der Folgebänder entsprechend dem gemessenen Verstellweg korrigiert. Zunächst wird beim Schären des ersten Bandes vor dem Schären des Meßwickels ein Basiswickel mit einem vorgegebenen Scnärschlittenvorschub geschärt und dessen Wickelumfang vom Tastorgan abgetastet, dessen Verstellweg in Abhängigkeit von der Anzahl der Umdrehungen gemessen wird. Dann wird das Tastorgan entsprechend des beim Schären des Basiswickels gemessenen Verstellwegs justiert und aus der Differenz zwischen dem gemessenen Verstellweg beim Meßwickel und dem gemessenen Verstellweg beim Basiswickel ein zum Schären des Restes des ersten Bandes vor-gesehener korrigierter Vorschub ermittelt. Alle weiteren Schärbänder werden wie das erste Band hinsichtlich des Basis- und Meßwikkels mit dem vorgegebenen Vorschub und der Restwickel mit dem korrigierten Schärschlittenvorschub geschärt.A method of warping threads on a warping drum a warping machine is from D2-OS 37 02 293 known. With this procedure, a warping becomes dependent of the increasing winding thickness relative to Warping drum moved by warping the first Belt with a specified skewer feed of the winding circumference by a feeler when the warping drum is at a standstill scanned and its adjustment path during a measuring winding phase depending on the number of Revolutions of the warping drum is measured. After that when warping the rest of the first warp and after copying the measuring roll when the subsequent belts are warmed the feed of the warping carriage during warping the rest of the following tapes according to the measured Adjustment path corrected. First, when the first tape before warping the measuring roll a base roll with a given feeder warmed and its winding circumference scanned by the feeler, its adjustment path depending on the number of revolutions is measured. Then the probe organ corresponding to that measured when the base winding was warmed Adjustment path adjusted and from the difference between the measured adjustment path for the measuring coil and the measured adjustment path for the base winding on for warping corrected the rest of the first volume Feed determined. All other warp bands will be like the first volume in terms of the base and measuring angle with the specified feed and the remaining wrap with the corrected skid carriage feed.

Der Nachteil des bekannten Verfahrens besteht darin, daß ein stufiger Wickel auf Grund des dreiteiligen Aufbaus des ersten Schärbandes entsteht. Ein weiterer Nachteil besteht außerdem darin, daß, obwohl der korrigierte Vorschubwert bereits bekannt ist, die nachfolgenden Wickel in gleicher Weise, also auch mit Basis-und Meßwickel mit ursprünglich vorgegebenen Schärschlittenvorschub gewickelt werden müssen, um einen gleichen Aufbau aller nachfolgenden Schärbänder zu gewährleisten.The disadvantage of the known method is that a step wrap due to the three-part structure of the first warp belt is created. Another Another disadvantage is that although the corrected Feed value is already known, the following Wrap in the same way, including base and Measuring roll with originally specified skewer feed need to be wrapped around a to ensure the same structure of all subsequent warping belts.

Aus der DE 40 07 620 C2 ist dabei bekannt, die Auftragsdicke mit Hilfe einer Laserlicht-Entfernungsmeßeinrichtung zu bestimmen, die auf eine gegen den Wickelaufbau gepreßte Andruckplatte gerichtet ist.From DE 40 07 620 C2, the thickness of the coating is known with the help of a laser light distance measuring device to determine the one against the Winding structure pressed pressure plate is directed.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Schärmaschine zu schaffen, bei der die Funktionen von Schärriet und Auftragsdicken-Meßeinrichtung nicht miteinander kollidieren.The invention has for its object a generic To create warping machine in which the Functions of Schärriet and application thickness measuring device do not collide with each other.

Diese Aufgabe wird erfindungsgemäß durch die Merkmal des Anspruchs 1 gelöst.This object is achieved by the feature of claim 1 solved.

Bei dieser Ausgestaltung kann die Auftragsdicken-Meßeinrichtung über dem gerade aufzuwickelnden Schärband, also in Umfangrichtung versetzt zum Schärriet, gehalten werden. Die Fadenschar kann ohne Umlenkung von Schärriet auf den Wickel geführt werden.With this configuration, the application thickness measuring device can over the warp to be wound up, thus offset circumferentially to the Schärriet, being held. The thread sheet can be deflected without by Schärriet on the reel.

In vorteilhafter Weise ist vorgesehen, daß das Schären von Anfang an vollautomatisch und ohne Materialverlust erfolgen kann. Hierzu sind zu Beginn des Schärprozesses ein Start- sowie eine Lernphase vorgesehen. In der Startphase wird zunächst ein Anfangswert für die Vorschubgeschwindigkeit in Abhängigkeit von den Kettparametern, z.B. der Gesamtfadenzahl der Kettbreite und der Garnnummer bestimmt. Dieser vorläufige, theoretisch bestimmte Vorschubgeschwindigkeitswert wird zumindest für die erste Umdrehung der Schärtrommel als Vorschubgeschwindigkeitssignal verwendet. Die Lernphase beginnt entweder mit der Startphase oder im Anschluß an die Startphase, wobei in der Lernphase kontinuierlich berührungslos die Auftragsdicke des Schärbandes gemessen wird, indem eine Auftragsdicken-Meßeinrichtung in einem vorgegebenen, im wesentlichen konstanten Abstand von der Oberfläche des gerade aufgewickelten Schärbandes gehalten wird. Der im wesentlichen konstante Abstand von der Oberfläche der Fadenschar ist erforderlich, um die Auftragsdicken-Meßeinrichtung in ihrem optimalen Meßabstand von der Schärbandoberfläche zu halten, da es auf eine äußerst genaue Entfernungsmessung ankommt. Aus den Signalen der Auftragsdicken-Meßeinrichtung kann die Auftragsdicke ermittelt werden und in Abhängigkeit von der Auftragsdicke die Vorschubgeschwindigkeit frühestens ab der zweiten Umdrehung der Schärtrommel geregelt werden.It is advantageously provided that the warping fully automatic right from the start and without material loss can be done. This is at the beginning of the warping process a start and a learning phase are planned. In the Start phase is initially an initial value for the feed rate depending on the warp parameters, e.g. the total number of threads of the warp width and the Yarn number determined. This preliminary, theoretically determined Feed rate value is at least for the first rotation of the warping drum as a feed speed signal used. The learning phase begins either with the start phase or after the start phase, being continuous in the learning phase the contact thickness of the warping belt is measured without contact is by a coating thickness measuring device at a predetermined, substantially constant distance from the surface of the just wound up Warp is held. The essentially constant Distance from the surface of the thread sheet is required in order to measure the thickness of the coating their optimal measuring distance from the surface of the warp to keep as it is based on an extremely accurate distance measurement arrives. From the signals of the application thickness measuring device the application thickness can be determined and the feed rate depending on the thickness of the job at the earliest from the second turn of the Warping drum can be regulated.

Die Dauer der Lernphase ist von der Stabilisierung der von der Regelung vorgegebenen Vorschubgeschwindigkeitssignale abhängig. Diese Stabilisierung tritt je nach Garnqualität nach einer unterschiedlichen Anzahl von Umdrehungen, z.B. nach ca. 30 Umdrehungen ein. Wenn also eine gewisse Stabilisierung der Regelung erfolgt ist, wird eine vorbestimmte Anzahl von zuletzt erhaltenen Vorschubgeschwindigkeitssignalen herangezogen, um ein für die Arbeitsphase des Schärprozesses gültiges konstantes Vorschubgeschwindigkeitssignal festzulegen. Der gesamte restliche Schärprozeß wird mit dieser in der Lernphase bestimmten Vorschubgeschwindigkeit ausgeführt.The duration of the learning phase is from the stabilization of the feed rate signals specified by the control dependent. This stabilization occurs depending on Yarn quality after a different number of Revolutions, e.g. after about 30 turns. So if the regulation has stabilized to a certain extent, is a predetermined number of last received Feed speed signals used to a for the working phase of the warping process is constant Set feed rate signal. The whole The remaining warping process is carried out with this in the learning phase certain feed rate executed.

Es kann vorgesehen sein, daß zu Beginn der Lernphase die maximale Korrektur des Vorschubgeschwindigkeitssignals pro Meßzyklus der Auftragsdicken-Meßeinrichtung begrenzt wird. Auf diese Weise wird ein Aufschaukeln der Regelung verhindert. Die Korrektur des Vorschubgeschwindigkeitssignals erfolgt dann ggf. in mehreren Schritten in die gleiche Richtung, so daß ein starkes Überschwingen der Vorschubgeschwindigkeitssignale um den korrekten Vorschubgeschwindigkeitswert vermieden wird.It can be provided that at the beginning of the learning phase maximum correction of the feed rate signal limited per measuring cycle of the application thickness measuring device becomes. In this way, a rocking of the scheme prevented. The correction of the feed rate signal then takes place in several steps in the same direction, so that a strong overshoot of the Feed speed signals around the correct feed speed value is avoided.

Vorzugsweise ist vorgesehen, daß eine Laserlicht-Entfernungsmeßeinrichtung als Auftragsdicken-Meßeinrichtung verwendet wird. Für eine optimale Regelung wird ein Meßgerät mit einer hohen Auflösung der Meßwerte benötigt. Die berührungslose Entfernungsmessung mit dem Laser ermöglicht eine Auflösung von ca. 30 µm.It is preferably provided that a laser light distance measuring device as a coating thickness measuring device is used. For an optimal regulation a Meter with a high resolution of the measured values required. The non-contact distance measurement with the laser enables a resolution of approx. 30 µm.

Vorteilhaft kann vorgesehen sein, daß das konstante Vorschubgeschwindigkeitssignal in der Arbeitsphase auf den Mittelwert der in einer vorbestimmten Anzahl von Meßzyklen in der Lernphase erhaltenen Vorschubgeschwindigkeitssignale eingestellt wird, wenn eine ebenfalls vorgegebene, maximale Schwankungsbreite der geregelten Vorschubgeschwindigkeitssignale in der Lernphase unterschritten wird. Das Umschalten von der Lernphase in die Arbeitsphase erfolgt demzufolge dann, wenn die Standardabweichung, beispielsweise der letzten 10 oder 20 Vorschubgeschwindigkeitssignale, einen vorgegebenen maximalen Grenzwert unterschreitet.It can advantageously be provided that the constant Feed speed signal in the working phase the average of a predetermined number of Measuring cycles in the learning phase received feed rate signals is set if one also specified, maximum fluctuation range of the regulated Feed speed signals fallen below in the learning phase becomes. Switching from the learning phase to the Accordingly, the work phase occurs when the standard deviation, for example the last 10 or 20 feed speed signals, a predetermined maximum Falls below the limit.

Es ist vorgesehen, daß das konstante Vorschubgeschwindigkeitssignal zu Beginn der Arbeitsphase an die Steuerung rückgemeldet wird, um die erforderliche Windungsanzahl zur Einhaltung der an der Schärmaschine eingestellten Kettlänge zu ermitteln und der Motorsteuerung ein exaktes Zählsignal für den aktuellen Schärprozeß zu übergeben, der die Einhaltung der exakten Kettlänge garantiert. Dabei kann eine voreingestellte Windungsanzahl bei Bedarf korrigiert werden. Gleichzeitig kann die Steuerung bei Kapazitätsüberschreitung ein Warnsignal ausgeben. Wenn die Auftragshöhe überschritten wird kann eine automatische Abschaltung der Schärmaschine vorgesehen sein.It is contemplated that the constant feed rate signal to the controller at the beginning of the work phase is reported back to the required number of turns to comply with the set on the warping machine Determine warp length and the engine control an exact count signal for the current warping process passed, the adherence to the exact warp length guaranteed. A preset number of turns can be used be corrected if necessary. At the same time, the Control if the capacity is exceeded a warning signal output. If the order amount can be exceeded an automatic shutdown of the warping machine is provided his.

Die Auftragsdicken-Meßeinrichtung wird vorzugsweise synchron mit der Drehbewegung der Schärtrommeln und der Veränderung der Lage des Schärbandes bewegt. Dabei wird die Entfernungsmessung vorzugsweise auf die Mitte des Schärbandes gerichtet.The application thickness measuring device is preferred synchronized with the rotation of the warping drums and the Change in the position of the warp belt moves. Doing so the distance measurement preferably to the middle of the Warp.

Die erfindungsgemäße Vorrichtung zeichnet sich dadurch aus, daß die Auftragsdicken-Meßeinrichtung sowohl parallel zur Schärtrommelachse als auch orthogonal zur Schärtrommelachse synchron mit der Schärtrommeldrehung und der Lageveränderung des Schärbandes bewegbar ist, wobei die Auftragsdicken-Meßeinrichtung einen im wesentlichen konstanten, vorgegebenen Abstand von der Schärbandoberfläche einhält. The device according to the invention is characterized by this from that the application thickness measuring device both parallel to the warping drum axis as well as orthogonal to the warping drum axis synchronized with the warping drum rotation and the Change in position of the warping belt is movable, the Order thickness measuring device essentially one constant, predetermined distance from the surface of the warp comply.

Vorteilhaft kann die Auftragsdicken-Meßeinrichtung an dem das Schärriet tragenden Schlitten befestigt sein und die Nachführbewegung gemeinsam mit dem Schärriet ausführen. Es zeigen:

Mit 16 ist der Fahrmotor bezeichnet. Ein weiterer Motor 17 treibt eine Gewindeleitspindel 18 an, von der ein Support 20 längs der Schärtrommel 2 mittels einer Spindelmutter 19 hin- und herverschoben werden kann. The cone warping machine 1 has a warping drum 2 a cylindrical part 3 and a cone part 4. The Warping drum 2 is supported in bearings 6 by a base frame 7 worn, the base frame 7 is designed as a carriage and can back and forth on rails 9 by means of the wheels 8 be brought here. A motor 11 with an encoder drives by means of a transmission link 12 and one Pulley 13 on the shaft 5 and thus the warping drum 2, a brake 14 is provided for a brake disc 15 is. With 16 the traction motor is designated. Another Motor 17 drives a threaded lead screw 18 from a support 20 along the warping drum 2 by means of a Spindle nut 19 can be pushed back and forth.

Der Support 20 weist einen Schärschlitten 21 auf, der auf Führungen längs der Schärtrommel 2 mittels der Spindel 18 hin- und herverschoben werden kann. An dem Schärschlitten 21 ist ein weiterer Schlitten 23 höhenverstellbar angebracht. Der weitere Schlitten 23 trägt den Antriebsmechanismus für die Bewegung eines Schieberietes 25 quer zur Schärtrommel 2 und für die Höhenverstellung des weiteren Schlittens 23 mit den daran angebrachten weiteren Teilen, sowie einen Arm 48, der eine Auftragsdicken-Meßeinrichtung 55 orthogonal über der Trommelachse der Schärtrommel 2 in etwa mittig über dem gerade aufzuwickelnden Schärband hält.The support 20 has a warping slide 21 which Guides along the warping drum 2 by means of the spindle 18 can be pushed back and forth. On the warping carriage 21 a further carriage 23 is attached in a height-adjustable manner. The further carriage 23 carries the drive mechanism for the movement of a sliding rivet 25 across Warping drum 2 and for height adjustment further Slide 23 with the other parts attached to it, and an arm 48 which is a coating thickness measuring device 55 orthogonal to the warp axis of the warping drum 2 approximately in the middle of the one to be wound up Sash tape holds.

Ein Motor 28 treibt mittels der Übertragungsglieder 29,30 eine Welle 31 an, von der mehrere Antriebe abgeleitet sind. Das Schieberiet 25 befindet sich auf einem Kreuzschlitten 32. Von der Welle 31 führt ein Übertragungsglied 33 zu einem Schneckentrieb 34, der eine Gewindespindel 35 antreibt, die den Schlitten 32 in Querrichtung zu der Längsachse der Trommel 2 verschieben kann.

The shift of the reed 25 in The longitudinal direction of the drum 2 is therefore independent of the Displacement across the drum axis.

Auf der Welle 31 befindet sich ein Zahnrad 40, das mit einem weiteren Zahnrad 41 kämmt, dessen Welle 42 mit einem Schneckentrieb 43 verbunden ist, der die Spindel 44 antreibt. Die Spindelmutter 45· ist an dem Supportschlitten 21 befestigt, so daß bei Betätigung der Spindel 44 der Schlitten 23 in der Höhe verschoben wird.On the shaft 31 is a gear 40, which with another gear 41 meshes, the shaft 42 with a worm drive 43 which connects the spindle 44 drives. The spindle nut 45 is on the support slide 21 attached so that when the spindle is actuated 44 the carriage 23 is moved in height.

Fig. 2 zeigt den Wickelbau des ersten Schärbandes bei einem Konusteil 4 mit einem Konuswinkel α zur Trommelachse von 15°.Fig. 2 shows the winding construction of the first warp a cone part 4 with a cone angle α to the drum axis of 15 °.

Mit h wird die Auftragshöhe pro Trommelumdrehung bezeichnet, so daß sich der theoretische Vorschub sv pro Trommelumdrehung aus sv = h/tan α berechnet.The order amount per drum revolution is denoted by h, so that the theoretical feed rate s v per drum revolution arises s v = h / tan α calculated.

Das Verfahren zum Schären von Fäden läuft insofern automatisch ab, als vom Beginn des Schärprozesses an ohne Unterbrechung des Wickelvorgangs die gesamte Kette aufgewickelt werden kann, wobei auch der erste Wickel von Anfang an mit einer optimalen Vorschubgeschwindigkeit gewickelt wird.In this respect, the process for warping threads runs automatically than as from the beginning of the warping process without Interrupting the winding process the entire chain is wound up can be, the first coil of Right from the start with an optimal feed rate is wrapped.

In der Startphase gibt der Steuerungsrechner 64 ein Anfangssignal für die Vorschubgeschwindigkeit sv an eine Synchronlaufsteuerung 62, die ihrerseits die Antriebe 17 und 28, das ist der Supportmotor und der Motor für die Höhenverstellung, synchron zu der Trommeldrehung steuert. Der Anfangswert berechnet sich aus den Kettparametern, z.B. der Gesamtfadenzahl der Kettbreite und der Garnnummer, indem beispielsweise die Gesamtfadenzahl durch die Kettbreite und die Garnnummer dividiert wird. Der sich ergebende Anfangswert für die Vorschubgeschwindigkeit wird nur für die erste oder die ersten Umdrehungen benötigt.In the starting phase, the control computer 64 gives an initial signal for the feed speed s v to a synchronous control 62, which in turn controls the drives 17 and 28, that is the support motor and the motor for the height adjustment, synchronously with the drum rotation. The initial value is calculated from the warp parameters, for example the total number of threads of the warp width and the thread number, for example by dividing the total number of threads by the warp width and the thread number. The resulting initial value for the feed rate is only required for the first or the first revolutions.

Dieser erste vorläufige Vorschubwert stellt dabei bereits eine sehr gute Näherung an den endgültigen, noch festzustellenden Vorschubwert dar, so daß das Aufschären praktisch von der ersten Wickellage an mit dem erforderlichen Vorschubwert erfolgt.This first preliminary feed value already represents a very good approximation of the final one to be determined Feed value, so that the skiving practically from the first winding position with the required Feed value is done.

Spätestens ab der zweiten Umdrehung beginnt die Lernphase, in der mit Hilfe der Auftragsdicken-Meßeinrichtung 55 kontinuierlich berührungslos die Auftragsdicke des Schärbandes erfaßt.wird, indem ein Abstandsignal an einen Vorschubrechner 60 weitergeleitet wird. Gleichzeitig erfassen zwei mit umfangsmäßigen Abstand von einander am Trommelumfang angeortete Initiatoren 66,68 die Drehbewegung der Schärtrommel 2 sowie deren Drehrichtung. Die Initiatoren geben ihre Signale ebenfalls an den Vorschubrechner 60 weiter und starten diesen.The learning phase begins at the latest from the second turn, in the with the help of the application thickness measuring device 55 continuously the contact thickness of the Warping band is detected by a distance signal to a Feed calculator 60 is forwarded. simultaneously capture two at a circumferential distance from each other Initiators 66,68 located around the drum circumference the rotary movement the warping drum 2 and its direction of rotation. The Initiators also send their signals to the feed computer 60 continue and start this.

Ab der zweiten Trommelumdrehung erhält der Vorschubrechner Auftragsdicken-Meßsignale, aus denen der Vorschubrechner 60 korrigierte Vorschubgeschwindigkeiten bestimmen kann und ein Regelsignal sv-Regel an die Synchronlaufsteuerung 62 weitergeben kann, die mit den Motoren 17 und 28 die Vorschubgeschwindigkeit und die Höhe des Schärriets 25 ändern können. Die Auftragsdicken-Meßeinrichtung 55 wird dabei aufgrund der Befestigung an dem Schlitten 23 mitbewegt. Die Auftragsdicken-Meßeinrichtung 55 wird außerdem in Höhenrichtung verstellt, und zwar so, daß ein im wesentlichen konstanter Abstand von ca. 50 mm von der Schärbandoberfläche eingehalten wird. Auf diese Weise befindet sich die Laserlicht-Entfernungsmeßeinrichtung, die als Auftragsdicken-Meßeinrichtung 55 verwendet wird, stets im optimalen Meßbereich, so daß mit sehr hoher Genauigkeit der Abstand des Meßkopfes zur Schärbandoberfläche und damit die Auftragsdicke berührungslos gemessen werden kann. Die Auflösung der Laserlicht-Entfernungsmeßeinrichtung beträgt ca. 30 µm. Ein eventueller Schlag der Schärtrommel 2 kann herausgefiltert und bei der Auftragsdickenmessung berücksichtigt werden.From the second drum revolution, the feed computer receives order thickness measurement signals, from which the feed computer 60 can determine corrected feed speeds and pass a control signal s v -Rule to the synchronous control 62, which change the feed speed and the height of the warping blade 25 with the motors 17 and 28 can. The application thickness measuring device 55 is moved due to the attachment to the carriage 23. The application thickness measuring device 55 is also adjusted in the vertical direction in such a way that an essentially constant distance of approximately 50 mm from the warping belt surface is maintained. In this way, the laser light distance measuring device, which is used as the coating thickness measuring device 55, is always in the optimal measuring range, so that the distance between the measuring head and the warping belt surface and thus the coating thickness can be measured without contact with very high accuracy. The resolution of the laser light distance measuring device is approx. 30 µm. A possible blow of the warping drum 2 can be filtered out and taken into account when measuring the application thickness.

In der Lernphase fallen ca. alle 40 ms neue Meßwerte zur Auftragsdicke an. Zu Beginn der Auftragsdickenmessung wird zweckmäßigerweise der Umfang der Korrektur der Vorschubgeschwindigkeitssignale begrenzt, um Regelschwingungen zu vermeiden. Nach einer bestimmten Anzahl von Trommelumdrehungen stabilisieren sich die geregelten Vorschubgeschwindigkeitssignale, indem die Schwankungsbreite aufeinanderfolgender Signale sich verringert. Nach Stabilisierung der geregelten Vorschubgeschwindigkeitssignale, z.B. nach 20 bis 30 Umdrehungen der Trommel, kann in Abhängigkeit von einem Grenzwert für die Standardabweichung oder anderen Grenzwerten die Lernphase beendet werden und der Mittelwert der letzten Vorschubgeschwindigkeitssignale als für den restlichen Schärprozeß verbindliches, konstantes Vorschubgeschwindigkeitssignal vorgeschrieben werden. Es ist damit sichergestellt, daß eine optimale Vorschubgeschwindigkeit automatisch ermittelt und einheitlich für den gesamten Schärprozeß herangezogen wird. In der Arbeitsphase werden also alle nachfolgenden Schärbänder von Anfang an ohne erneute Messung der Auftragsdicke mit diesem endgültigen Vorschub geschärt. Gegenüber dem ersten Schärband ergibt sich für die nachfolgenden Schärbänder kein unterschiedlicher Aufbau des Wickels, da der endgültige Vorschub bereits nach wenigen Wickellagen eingestellt worden ist.In the learning phase, new measured values are added approximately every 40 ms Order thickness. At the beginning of the thickness measurement the scope of the correction of the Feed rate signals limited to control vibrations to avoid. After a certain number of regulated drum revolutions stabilize Feed rate signals by the fluctuation range successive signals are reduced. To Stabilization of the regulated feed speed signals, e.g. after 20 to 30 revolutions of the drum, can depend on a standard deviation limit or other limits the learning phase and the average of the last feed speed signals than for the rest of the warping process binding, constant feed rate signal be prescribed. This ensures that an optimal feed speed automatically determined and uniform for the entire warping process is used. So everyone is in the work phase subsequent warp belts from the beginning without renewed Measure the thickness of the job with this final feed warped. Compared to the first warp belt, for the following warp bands no different Structure of the wrap since the final feed is already has been set after a few winding layers.

Der nach Abschluß der Lernphase und zu Beginn der Arbeitsphase festgelegte Endwert des Vorschubgeschwindigkeitssignals wird an den Steuerungsrechner 64 von dem Vorschubrechner 60 zurückgemeldet, damit der Steuerungsrechner 64 die exakte Windungsanzahl bestimmen kann, um die an dem Bedienfeld 56 der Steuerung eingestellte Kettlänge exakt einzuhalten.That after the end of the learning phase and at the beginning of the working phase fixed end value of the feed rate signal is sent to the control computer 64 from the Feed computer 60 reported back so that the control computer 64 can determine the exact number of turns, around the one set on the control panel 56 of the control Comply with warp length exactly.
