- the anvil 7 has a hardened surface 8, in front of which a yarn 9, for example is moved past in the direction of an arrow 10. Parts can be seen on carrier 1 of two screw connections 11 and 12, via which the device on a textile machine can be attached.

For example the tensile strength or hairiness of the yarn previously measured in the laboratory, or any other property that affects the force required for a cut. In this way, the kinetic energy can be supplied to the knife in doses and depending on it the cross-section or other properties of the yarn.
- the cross section is measured before cutting, for example, and the measurement value obtained in this way used to measure the kinetic energy by the controller 26.

Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Schneiden von Garn auf einer Textilmaschine, mit einem Messer, wobei dem Messer über einen Antrieb Bewegungsenergie zugeführt wird (siehe DE-A-2 132 137).The invention relates to a method and an apparatus for cutting yarn on a Textile machine, with a knife, the knife being driven by kinetic energy is supplied (see DE-A-2 132 137).
Solche Vorrichtungen sind insbesondere auf Textilmaschinen, wie beispielsweise auf Spulmaschinen angeordnet. Dort sind sie zum Herausschneiden von Fehlern, wie z. B. Dickoder Dünnstellen im Garn, vorgesehen. Das Schneiden erfolgt dabei mit einem beweglich gelagerten Messer, das das Garn gegen eine Gegenhaltung drängt und, wenn es darauf aufliegt, durchtrennt. Dazu soll das Messer genügend Bewegungsenergie aufnehmen, bevor es auf das Garn trifft. Es ist dabei üblich, das Messer so stark zu beschleunigen, dass es mit seiner kinetischen Energie alle denkbaren Garne rasch durchtrennen kann. Überschüssige Energie wird auf der Gegenhaltung vernichtet. Oder, das Messer erhält die gemäss den gegebenen Umständen gerade verfügbare Energie. Dann kann die dem Messer zugeführte Energie willkürlich schwanken.Such devices are particularly on textile machines, such as on winding machines arranged. There they are for cutting out errors, such as B. Dickoder Thin spots in the yarn, provided. The cutting is done with a movable stored knife that pushes the yarn against a backing and when it is on it rests, severed. To do this, the knife should absorb enough kinetic energy before it hits the yarn. It is common to accelerate the knife so much that with its kinetic energy it can quickly cut through all conceivable yarns. excess Energy is destroyed on the counterhold. Or, the knife receives the according given the current available energy. Then the knife supplied energy fluctuate arbitrarily.
Bei bekannten Vorrichtungen, werden für den Antrieb sogenannte Tauch- oder Klappanker verwendet, wobei das Messer mit dem Anker verbunden ist.In known devices, so-called submersible or folding anchors are used for the drive used, the knife being connected to the anchor.
Ein Nachteil solcher bekannter Vorrichtungen ist darin zu sehen, dass die Schneidkraft des Messers auf die dicksten Garne ausgelegt ist, die voraussichtlich durch die Vorrichtung bearbeitet werden könnten, oder, dass ganz einfach der Antrieb immer seine volle oder die gerade zur Verfügung stehende Leistung abgibt. Dies führt praktisch dazu, dass das Messer zu stark oder zu schnell abgenützt wird und dass die ganze Vorrichtung an sich unnötig starke Erschütterungen erfährt.A disadvantage of such known devices is that the cutting force of the Knife is designed for the thickest yarn that is expected to be processed by the device could be, or that quite simply the drive always its full or the delivers the currently available service. This practically results in the knife is worn too strongly or too quickly and that the whole device itself is unnecessary experiences strong shocks.
Es ist deshalb eine Aufgabe der Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, ein Verfahren und eine Vorrichtung zu schaffen, die diese Nachteile vermeidet, und die immer eine genügende Schneidkraft erzeugt.It is therefore an object of the invention as characterized in the claims to provide a method and a device which avoids these disadvantages and which always generates a sufficient cutting force.
Dies wird dadurch erreicht, dass die Bewegungsenergie dosiert zugeführt wird und in Abhängigkeit einer Eigenschaft aus einer Gruppe bemessen wird. Diese Gruppe umfasst Eigenschaften des Materials aus dem das Gam besteht, Durchmesser, Querschnitt, Masse des Garns usw., sowie Eigenschaften der Vorrichtung, die zum Schneiden verwendet wird. This is achieved in that the kinetic energy is supplied in a dosed and dependent manner a property from a group is measured. This group includes properties of the material from which the gam is made, diameter, cross-section, mass of the yarn, etc., as well as properties of the device used for cutting.
Eine solche Eigenschaft ist beispielsweise die Trägheit der mit dem Messer bewegten Massen und des Messers an sich, die Charakteristik des Reibungswiderstandes des bewegten Messers usw. Vorzugsweise wird eine Eigenschaft wie beispielsweise der Durchmesser oder der Querschnitt des Gams unmittelbar vor dem Schnitt d.h. laufend gemessen und der gemessene Wert wird bei der Bemessung der zugeführten Energie berücksichtigt. Deshalb weist der Antrieb eine Vorrichtung zur Bemessung der Bewegungsenergie des Messers auf.One such property is, for example, the inertia of the masses moved with the knife and the knife itself, the characteristic of the frictional resistance of the moving Knife etc. Preferably a property such as the diameter or the cross section of the chamois immediately before the cut i.e. continuously measured and the The measured value is taken into account when dimensioning the supplied energy. Therefore the drive has a device for measuring the kinetic energy of the knife.
Die dadurch erreichten Vorteile sind insbesondere darin zu sehen, dass das Messer, die Gegenhaltung oder der Amboss und überhaupt die ganze Vorrichtung mit der Aufhängung geschont wird. Femer werden unerwünschte Nebeneffekte vermieden, wie beispielsweise das starke Zurückfedern des Messers, das mit zuviel überschüssiger Energie auf der Gegenhaltung aufprallt. Da die Bemessung der Bewegungsenergie eine Beschränkung sowie auch eine Erhöhung der am Antrieb angelegten Spannung bewirken kann, kann auch dann ein einwandfreier Schnitt des Gams durchgeführt werden, wenn die Textilmaschine eine an sich ungenügende Spannung an die Vorrichtung liefert.The advantages achieved by this can be seen in particular in the fact that the knife Brace or the anvil and the whole device with the suspension is spared. Unwanted side effects are also avoided, such as the strong springback of the knife, that with too much excess energy on the counterhold impacts. Because the measurement of kinetic energy is a limitation as well can also cause an increase in the voltage applied to the drive A perfect cut of the chamois can be done when the textile machine is one insufficient voltage is supplied to the device.
Im folgenden wird die Erfindung anhand eines Beispiels und mit Bezug auf die vorliegenden
Zeichnungen näher erläutert. Es zeigen:
Fig. 1 zeigt die wichtigsten Teile der Vorrichtung, insbesondere einen Träger 1, eine Tauchspule
2 mit der Spule 3 und dem Tauchanker 4, die einen Antrieb für einen Messerhalter 5
und so auch für ein Messer 6 bilden und eine Gegenhaltung oder ein Amboss 7, der Teil
des Trägers 1 ist. Der Amboss 7 weist eine gehärtete Fläche 8 auf, vor der ein Garn 9 beispielsweise
in Richtung eines Pfeiles 10 vorbeibewegt wird. Am Träger 1 erkennt man Teile
von zwei Schraubverbindungen 11 und 12, über die die Vorrichtung auf einer Textilmaschine
befestigt werden kann. Das Messer 6 ist vorzugsweise fest mit dem Messerhalter
5 verbunden, der seinerseits hier über eine lösbare formschlüssige Verbindung 13 mit dem
Tauchanker 4 verbunden ist. Es ist an sich bekannt, und deshalb hier nicht näher dargestellt,
dass die Spule 3 Windungen ausweist, die an eine in dieser Figur nicht gezeigte
Steuerschaltung 14 angeschlossen sind.Fig. 1 shows the most important parts of the device, in particular a
Fig. 2 zeigt eine Steuerschaltung 14 als Vorrichtung zur Bemessung der Bewegungsenergie
des Messers 6, die über eine Leitung 15 mit einer Schneidvorrichtung 16 verbunden ist. Die
Schneidvorrichtung 16 ist dabei vorzugsweise wie in Fig. 1 gezeigt aufgebaut. Die Leitung
15 ist dabei über eine Leitung 19 und ein Schaltelement 17 mit einem Energiespeicher 18,
hier als Kondensator ausgebildet, verbunden, der weiter an einen Spannungswandler 20
angeschlossen ist. Dieser wiederum ist über eine Leitung 21 und ein weiteres Schaltelement
22 mit einer Speiseschaltung 23 verbunden. Die Schaltelemente 22 und 17 sind
über Leitungen 24 und 25 mit einer Steuerung 26 verbunden, die zudem zwei Eingänge 27
und 28 aufweist. Der Eingang 27 ist mit der Leitung 19 verbunden und der Eingang 28 ist
entweder mit einem Gammessgerät 29 oder einer Dateneingabe 30 verbunden.Fig. 2 shows a
Der Spannungswandler 20 kann beispielsweise als Gleichstromwandler oder als Ladungspumpe
ausgebildet sein. Für die Steuerung 26 wird vorzugsweise ein entsprechend der
nachfolgend beschriebenen Wirkungsweise programmierter Mikroprozessor verwendet.The
Die Wirkungsweise der Erfindung ist wie folgt beschrieben:The operation of the invention is described as follows:
Die Speiseschaltung 23, welche beispielsweise Teil einer Textilmaschine ist, gibt eine Speisespannung
von z.B. 30V - 60V an die Leitung 21 und das Schaltelement 22 ab. In geschlossenem
Zustand wird damit der Spannungswandler 20 gespeist, der die angelegte
Spannung umwandelt, d.h. erhöht oder beschränkt und über Leitung 19 den Kondensator
18 auflädt Am Eingang 28 liegt an der Steuerung 26 ein Signal an, das eine Eigenschaft
des Garns und/oder der Vorrichtung (Trägheit, Reibung, usw.) angibt. Eine solche Eigenschaft
des Gams kann einerseits abhängig von der Qualität des Materials sein, oder sie
kann abhängig von der Quantität des Materials sein. In die erste Gruppe gehören Eigenschaften
wie beispielsweise die Zugfestigkeit, das Elastizitätsmodul, die innere Dämpfung,
das Energieabsorptionsvermögen, oder eben Eigenschaften die vom verwendeten Rohstoff
und der gewählten Verarbeitung usw. abhängen. In die zweite Gruppe gehören Eigenschaften
wie der Querschnitt, der Durchmesser oder die Masse usw. des Garns. Am Eingang 27
liegt ein Signal an, das die Ladespannung des Kondensators 18 angibt. Aus den Signalen
der Eingänge 27 und 28 bestimmt die Steuerung 26 ob das Schaltelement 22 geöffnet werden
muss, weil der Kondensator 18 beispielsweise dem vorhandenen Querschnitt und Material
des Garns entsprechend genügend aufgeladen ist. Das Schaltelement 17 wird geschlossen,
wenn ein Schnitt ausgeführt werden muss, was von der Steuerung 26 oder einem
anderen Element ausgelöst wird. Dann wird die Spule 3 durch die Spannung in der
Leitung 15 erregt, sodass der Tauchanker 4 sich in Fig. 1 gegen den Amboss 7 hin bewegt
und das Messer 6 das Garn 9 gegen die Fläche 8 drängt und dort trennt. Das Schaltelement
17 wird über die Leitung 25 nach einer Zeit, die für einen Schnitt genügt, z.B. nach 10
Millisekunden, wieder geöffnet Danach wird das Schaltelement 22 über die Leitung 24 wieder
geschlossen, bis der Kondensator 18 wieder die gewünschte Ladespannung aufweist. The
Die Ladespannung ist dann angepasst, wenn sie proportional dem Widerstand ist, den das
Garn dem Schnitt durch das Messer entgegensetzt. Dieser Widerstand ist gross, wenn das
Garn einen grossen Querschnitt, d.h. viele und/oder dicke oder zähe Fasern, hat, oder
klein, wenn das Garn einen kleinen Querschnitt, d.h. wenige und/oder dünne oder weiche
Fasem aufweist. Durch eine geeignete Eingabe über die Dateneingabe 30 können auch
weitere, vom verwendeten Material abhängige Faktoren berücksichtigt werden. Beispielsweise
die im Labor vorgängig gemessene Zugfestigkeit oder Haarigkeit des Garns, oder
irgendeine andere Eigenschaft, die die Kraft beeinflusst, die für einen Schnitt benötigt wird.
So kann die Bewegungsenergie dem Messer dosiert zugeführt werden und in Abhängigkeit
des Querschnitts oder anderer Eigenschaften des Garns bemessen werden. Der Querschnitt
wird vor dem Schneiden beispielsweise gemessen und der so erhaltene Messwert
zur Bemessung der Bewegungsenergie durch die Steuerung 26 verwendet. Die Bewegungsenergie
wird somit vorgängig als elektrische Spannung beispielsweise im Kondensator
18 gespeichert. Die elektrische Spannung kann dabei nicht nur dem Querschnitt
des Garns sondern auch der Masse des Messers 6 und weiterer bewegter Teile 4, 5 oder
anderen Eigenschaften des Antriebs angepasst sein.The charging voltage is adjusted if it is proportional to the resistance that the
Oppose the cut by the knife. This resistance is great if that
Yarn has a large cross-section, i.e. many and / or thick or tough fibers, has, or
small if the yarn has a small cross-section, i.e. few and / or thin or soft
Has fibers. A suitable input via the
Die Vorrichtung kann auch so ausgebildet sein, dass die Funktion des Schaltelementes 22
im Spannungswandler 20 wahrgenommen wird. In diesem Falle fällt das Schaltelement 20
weg und die Leitung 24 verbindet die Steuerung 26 direkt mit dem Spannungswandler 20.The device can also be designed such that the function of the
