Description
Die Erfindung bezieht sich auf eine Maschine zum Bilden von Wattewickeln aus zulaufender Watte, mit einer Halterung für eine Wickelhülse, mit wenigstens einem bewegbaren Antriebselement zum Bewegen des Umfangs des Sattewickels und mit einer Belastungseinrichtung zum Gegeneinanderdrücken des Wattewickels und des Antriebselements mit einer von einer Steuereinrichtung steuerbaren, vom Durchmesser des Wattewickels abhängigen Kraft.The invention relates to a machine for forming cotton rolls incoming cotton, with a holder for a winding tube, with at least one movable drive element for moving the circumference of the saddle wrap and with a loading device for pressing the cotton roll against one another Drive elements with a diameter that can be controlled by a control device force dependent on the wadding.
In bekannten Maschinen dieser Art enthält die Steuereinrichtung, welche beispielsweise ein Druckreduzierventil der Belastungseinrichtung steuert, ein mechanisches Element, welches mit wachsenden Durchmesser des Wattewickels mechanisch bewegt wird. Wenn die Anordnung so ist, dass sich die Wickelhülse mit dem wachsenden Durchmesser des Wattewickels verschiebt, kann das mechanische Element mit der Halterung der Wickelhülse bewegt werden. Das Element kann für die Betätigung des Druckreduzierventils eine Kurve aufweisen. Solche mechanischen Systeme sind relativ unflexibel.In known machines of this type, the control device contains which controls, for example, a pressure reducing valve of the loading device mechanical element, which with increasing diameter of the cotton roll is moved mechanically. If the arrangement is such that the winding tube with the growing diameter of the wadding can shift mechanical Element are moved with the holder of the winding tube. The item can be used for Actuation of the pressure reducing valve have a curve. Such mechanical Systems are relatively inflexible.
Andere bekannte Maschinen enthalten für die Steuerung der Belastungseinrichtung eine elektronische Steuereinrichtung, der ein Signal zugeführt wird, welches den Durchmesser des Wattewickels darstellt. Für die Erzeugung dieses Signals kann ein mechanisches Führerelement verwendet werden oder aber, wenn sich die Wickelhülse im Betrieb nicht verschiebt, ein Näherungssensor, z.B. Ultraschallsensor.Other known machines include for the control of the loading device an electronic control device, to which a signal is supplied which corresponds to the Represents diameter of the wadding. A can be used to generate this signal mechanical guide element can be used or if the winding tube does not move during operation, a proximity sensor, e.g. Ultrasonic sensor.
Die Aufgabe der Erfindung besteht darin, den Aufbau einer Maschine der eingangs angegebenen Art zu vereinfachen.The object of the invention is to build a machine of the beginning to simplify the specified type.
Die erfindungsgemässe Maschine, mit der die Aufgabe gelöst wird, ist dadurch gekennzeichnet, dass der Steuereinrichtung ein Signal zugeführt ist, welches die kumulierte Länge der dem Wattewickel zulaufenden Watte darstellt, und dass die Steuereinrichtung Rechnermittel enthält zum Berechnen des Durchmessers des Wattewickels aus diesem Signal und aus weiteren Signalen, welche das Gewicht der Watte in Gewichtseinheiten pro Längeneinheit, das spezifische Gewicht der Watte, die Breite des Wattewickels und den Durchmesser der Wickelhülse darstellen.The machine according to the invention, with which the object is achieved, is thereby characterized in that the control device is fed a signal which the is the cumulative length of the cotton tapering to the cotton roll, and that the Control device contains computer means for calculating the diameter of the Cotton wrap from this signal and from other signals, which the weight of the Cotton wool in units of weight per unit length, the specific weight of the cotton wool Represent the width of the cotton roll and the diameter of the winding tube.
In dieser Maschine ist kein Fühler oder Sensor für die Erzeugung des den Durchmesser des Sattewickels darstellenden Signals erforderlich.In this machine there is no sensor or sensor for the generation of the Diameter of the signal representing the satin wrap is required.
Das die kumulierte Länge der dem Wattewickel zulaufenden Watte darstellende Signal steht in Maschinen zum Bilden von Wattewickeln stets ohnehin zur Verfügung, weil es erwünscht ist, auf dem Wickel eine vorbestimmte Wattelänge aufzuwickeln.The signal representing the cumulative length of the cotton tapering to the cotton roll is always available anyway in machines for forming wadding because it is it is desired to wind a predetermined wad length on the wrap.
Die genannten weiteren Signale können manuell in die Steuereinrichtung eingegeben werden; die entsprechenden Grössen sind im allgemeinen von vornherein bekannt. Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnung erläutert. Darin zeigen:

In der Maschine gemäss Fig. 1 ist eine Wickelhülse 1 durch eine Halterung in Form von
zwei gestellfesten, axial in die Wickelhülse 1 einführbaren Zapfen 2 drehbar gehalten.
Auf der Wickelhülse 1 wird eine zulaufende Watte 4, die von Kalanderwalzenpaaren 5,
6, 7 kommt, aufgewickelt, um einen Wattewickel 8 zu bilden. Um den Wattewickel 8
(bzw. anfänglich um die Wickelhülse 1) ist ein endloser Antriebsriemen 9 gelegt, der um
Umlenkrollen 10, 11, 12, 13, 14 geführt ist. Der Antriebsriemen 9 wird durch Drehen
einer oder mehrerer dieser Rollen, beispielsweise der Rolle 10 und/oder der Rolle 11,
bewegt.In the machine according to FIG. 1, a
Dabei wird der Antriebsriemen 9 an den Umfang des Wattewickels 8 angedrückt, indem
im Antriebsriemen eine Zugkraft erzeugt wird. Diese Zugkraft wird von einem
Pneumatikzylinder 15 erzeugt, dessen Kolbenstange mit der im Maschinengestell
horizontal verschiebbar angeordneten Umlenkrolle 14 verbunden ist. Die Erfahrung
lehrt, dass die Andrückkraft des Riemens 9 an den Umfang des Wattewickels 8 bzw.
die Zugkraft im Riemen 9 im Verlaufe des Aufbaus des Sattewickels verändert werden
muss, damit ein gegenseitiges Verfilzen der Wattelagen auf dem Wickel und ein
Abheben der Watte vom Wickel bei hoher Geschwindigkeit vermieden werden. Es ist
wünschbar, dass der Wattewickel hart ist, aber ohne gegenseitiges Verhängen der
Fasern benachbarter Wattelagen, da ein solches Verhängen später beim Abwickeln der
Watte von dem Wickel zu abstehenden Fasern führen könnte. In der Regel muss die
Andrückkraft des Riemens 9 an den Umfang des Wattewickels 8 mit wachsendem
Durchmesser des Wattewickels kleiner werden, weil sonst ein zu starkes Walken auf
dem Umfang des Wattewickels auftreten könnte.The
Die Fig. 2 zeigt eine Funktion, nach der die Grösse der Zugkraft F im Antriebsriemen 9
in Abhängigkeit vom Durchmesser d des Wattewickels in einem speziellen
Anwendungsbeispiel abnehmen sollte. Eine solche Funktion kann in eine elektronische
Steuereinrichtung 16 (Fig. 1) eingegeben werden. Dabei ist es ohne weiteres möglich,
dass die Funktion im Steuergerät 16 für verschiedene Anwendungsfälle einstellbar ist.
Die Steuereinrichtung 16 steuert eine Pumpe 17 und ein Druckregelventil 18, welche
den Pneumatikzylinder 15 speisen.2 shows a function according to which the magnitude of the tensile force F in the
Dem Steuergerät 16 sollte natürlich im Verlauf des Aufbaus des Sattewickels 8 stets
der momentane Durchmesser des Wattewickels bekannt sein.The
Alle Maschinen zum Bilden von Wattewickeln enthalten einen Sensor (Drehgeber), der
laufend die kumulierte Länge der dem Wattewickel zulaufenden Watte feststellt, damit
der Aufwickelvorgang abgebrochen werden kann, sobald auf dem Wattewickel eine
vorbestimmte Wattelänge aufgewickelt ist. In Fig. 1 ist als Sensor ein Drehgeber 19
dargestellt, der mit einer der Kalanderwalzen des letzten Kalanderwalzenpaares 7
gekuppelt ist. Der Drehgeber gibt ein Signal ab, welches die kumulierte Länge 1 der
dem Wattewickel 8 zulaufenden Watte 4 darstellt. Dieses Signal wird über eine Leitung
20 der Steuereinrichtung 16 zugeführt. Ferner werden der Steuereinrichtung 16 über
Leitungen 21 noch weitere Signale zugeführt, welche das Gewicht G der zugeführten
Watte 4 in Gewichtseinheiten pro Längeneinheit, das spezifische Gewicht y der Watte,
die Breite b der'zugeführten Wattebahn 4 bzw. des Wattewickels und den
Aussendurchmesser do der Wickelhülse 1 darstellen. Diese weiteren Signale bzw. die
Werte G, y, b und do können manuell in die Steuereinrichtung 16 eingegeben werden,
da die Werte in der Regel von vornherein bekannt sind bzw. im voraus ermittelt werden
können. Es ist daher im allgemeinen nicht erforderlich, einen oder mehrere dieser
Werte mittels jeweils eines Sensors laufend zu messen und die Messignale der
Steuereinrichtung 16 zuzuführen. Die Steuereinrichtung 16 enthält elektronische
Rechnermittel zum Berechnen des momentanen Durchmessers d des Wattewickels
aus den zugeführten Signalen nach der Formel
Die Fig. 3 zeigt schematisch Teile einer anderen Maschine zum Bilden von
Wattewickeln. In dieser Maschine ist eine Wickelhülse 31 durch eine Halterung in Form
von zwei axial in die Wickelhülse einführbaren Zapfen 32 drehbar gehalten. Die Zapfen
32 sind an Tragarmen 33 angebracht, deren untere Enden an Schwenkhebeln 34
angelenkt sind, die um eine gestellfeste Achse 35 schwenkbar gelagert sind. Auf die
Wickelhülse 31 wird eine zulaufende Watte 36, die von Kalanderwalzen 37, 38, 39, 40
kommt, aufgewickelt, um einen Wattewickel 41 zu bilden. Der Wattewickel 41 (bzw.
anfänglich die Wickelhülse 31) liegt auf zwei um gestellfeste Achsen drehbar
gelagerten, antreibbaren Wickelwalzen 42 und 43 auf. 3 schematically shows parts of another machine for forming
Cotton wrap. In this machine, a winding tube 31 is in shape by a bracket
held rotatably by two
Der Umfang des Wattewickels 41 wird an die Wickelwalzen 42 und 43 angedrückt,
indem die Tragarme 33 nach unten gezogen werden. Die Kraft wird von einem
Pneumatikzylinder 44 erzeugt, dessen Kolbenstange am Schwenkhebel 34 angelenkt
ist. Für die Andrückkraft des Wattewickels 41 an die Wickelwalzen 42, 43 gilt das im
Vorstehenden für die Andrückkraft des Riemens 9 an den Umfang des Wattewickels 8
in Fig. 1 Gesagte. Eine Steuereinrichtung 45, entsprechend der Steuereinrichtung 16 in
Fig. 1, steuert eine Pumpe 46 und ein Regelventil 47, welche den Pneumatikzylinder 44
speisen. Ein Drehgeber 48, der beispielsweise mit der Kalanderwalze 40 gekuppelt ist,
gibt ein Signal ab, welches die kumulierte Länge der dem Wattewickel 41 zulaufenden
Watte 40 darstellt. Dieses Signal wird über eine Leitung 49 der Steuereinrichtung 45
zugeführt. Über Leitungen 50 werden der Steuereinrichtung 45 weitere Signale
zugeführt, wie anhand der Fig. 1 beschrieben.The circumference of the
