Abstract

Die Kämmaschine besitzt wenigstens einen Kämmkopf, der eine kontinuierlich drehbare Rundkammwalze (1), ein schwingendes Zangenaggregat (3, 4) und wenigstens einen Abreisszylinder (9) enthält. Der Abreisszylinder (9) wird während jeder Umdrehung der Rundkammwalze (1) jeweils zuerst durch einen kleineren Winkel rückwärts gedreht und dann durch einen grösseren Winkel vorwärts gedreht. Diese Drehungen des Abreisszylinders (9) werden von wenigstens einem Elektromotor (18) erzeugt, dem von einer Elektronischen Programmsteuereinrichtung (25) die entsprechenden Antriebsimpulse zugeführt werden. Dank des Elektromotors (18) ist für den Antrieb des Abreisszylinders (9) kein kompliziertes und teures mechanisches Getriebe mit grossen hin- und herbewegten Massen erforderlich.The combing machine has at least one combing head which contains a continuously rotatable circular comb roller (1), a vibrating pliers unit (3, 4) and at least one tear-off cylinder (9). The tear-off cylinder (9) is first rotated backwards by a smaller angle during each revolution of the circular comb roller (1) and then rotated forward by a larger angle. These rotations of the tear-off cylinder (9) are generated by at least one electric motor (18), to which the corresponding drive pulses are supplied by an electronic program control device (25). Thanks to the electric motor (18), no complicated and expensive mechanical transmission with large reciprocating masses is required to drive the tear-off cylinder (9).

Description

Die Erfindung bezieht sich auf eine Kämmaschine mit wenigstens einem Kämmkopf, der eine kontinuierlich drehbare Rundkammwalze, ein hin- und herbewegbares Zan­genaggregat und wenigstens einen mit einer Pilgerschritt­bewegung drehbaren Abreisszylinder enthält.The invention relates to a combing machine with at least one combing head, which contains a continuously rotatable circular comb roller, a reciprocating pliers unit and at least one tear-off cylinder rotatable with a pilgrim step movement.

In bekannten Kämmaschinen dieser Art wird die Rundkammwalze von einem Antriebsmotor kontinuierlich ge­dreht. Der Abreisszylinder muss in jedem Kammspiel, d.h. in der Regel während jeder Umdrehung der Rundkamm­walze, zuerst durch einen bestimmten Winkel rückwärts gedreht werden und anschliessend durch einen anderen, grösseren Winkel vorwärts gedreht werden. Diese Bewegung des Abreisszylinders wird in den bekannten Kämmaschinen über ein mechanisches Getriebe von der Drehung der Rund­kammwalze abgeleitet. Ein solches Getriebe ist sehr kom­pliziert und daher teuer. Zudem enthält es relativ grosse hin und her zu bewegende Massen, die sich bei höheren Kammspielzahlen (Umdrehungszahlen der Rundkammwalze), z.B. 350 bis 400 pro Minute, nachteilig auswirken.In known combing machines of this type, the round comb roller is continuously rotated by a drive motor. The tear-off cylinder must be As a rule, during each revolution of the circular comb roller, first be rotated backwards by a certain angle and then rotated forwards by another, larger angle. In the known combing machines, this movement of the tear-off cylinder is derived from the rotation of the circular comb roller via a mechanical gear. Such a transmission is very complicated and therefore expensive. In addition, it contains relatively large masses that can be moved back and forth, which increase with higher comb play numbers (revolutions of the circular comb roller), e.g. 350 to 400 per minute, adversely affect.

Die Aufgabe der Erfindung besteht darin, in der eingangs angegebenen Kämmaschine den Antrieb für den Abreisszylinder so auszubilden, dass die erforderlichen Bewegungen des Abreisszylinders ohne teures Getriebe mit grossen hin und her zu bewegenden Massen erzeugt werden können.The object of the invention is to design the drive for the tear-off cylinder in the combing machine specified at the outset in such a way that the required movements of the tear-off cylinder can be produced with large masses which can be moved back and forth without expensive gear.

Die Aufgabe wird dadurch gelöst, dass in der er­findungsgemässen Kämmaschine zum Drehen des Abreiss­zylinders wenigstens ein Elektromotor angeordnet ist.The object is achieved in that at least one electric motor is arranged in the combing machine according to the invention for rotating the tear-off cylinder.

Der Elektromotor, z.B. ein bürstenloser Gleich­strommotor oder ein Asynchronmotor, kann von einer Steuereinrichtung mit Antriebsimpulsen gespeist werden, die mit der Drehung der Rundkammwalze synchronisiert sind, so dass der Motor den Abreisszylinder, vorzugs­weise über ein Untersetzungsgetriebe, während jedes Kammspiels zuerst rückwärts und dann vorwärts dreht. Es ist aber auch möglich, für das Rückwärts- und das Vor­wärtsdrehen des Abreisszylinders je einen gesonderten Elektromotor anzuordnen, wobei jeder Motor mit dem Ab­reisszylinder jeweils über eine Kupplung verbunden ist.The electric motor, for example a brushless DC motor or an asynchronous motor, can be fed by a control device with drive pulses which are synchronized with the rotation of the circular comb roller, so that the motor first rotates backwards and then forwards during each comb play, preferably via a reduction gear . It However, it is also possible to arrange a separate electric motor for the backward and forward rotation of the tear-off cylinder, each motor being connected to the tear-off cylinder via a coupling.

Ausführungsbeispiele der Erfindung werden nach­stehend anhand der Zeichnung näher erläutert. In dieser zeigen:

  • Fig. 1 Teile eines Kämmkopfes einer Kämmaschine in einem schematischen Vertikalschnitt,
  • Fig. 2 eine schematische Teildraufsicht auf die Abreisszylinder einer Kämmaschine mit mehreren Kämm­köpfen und
  • Fig. 3 in einer ähnlichen Draufsicht wie Fig. 2 eine Variante.
Embodiments of the invention are explained below with reference to the drawing. In this show:
  • 1 parts of a combing head of a combing machine in a schematic vertical section,
  • Fig. 2 is a schematic partial plan view of the tear-off cylinder of a combing machine with several combing heads and
  • Fig. 3 in a plan view similar to Fig. 2 shows a variant.

Der in Fig. 1 schematisch dargestellte Kämmkopf besitzt eine durch einen nicht dargestellten Antriebs­motor kontinuierlich drehbare Rundkammwalze 1, welche ein Rundkammsegment 2 trägt, und ein aus einer Unterzange 3 und einer Oberzange 4 bestehendes Zangenaggregat. Die Unterzange 3 ist bei ihrem vorderen Ende an um die Achse der Rundkammwalze 1 schwenkbaren Vorderstützen 5 ange­lenkt und ist bei ihrem hinteren Ende an Zangenarmen 6 angelenkt, welche auf einer hin- und herschwenkbaren Zangenwelle 7 sitzen. Die Oberzange 4 ist bezüglich der Unterzange 3 um eine Achse 8 schwenkbar. Weiter besitzt der Kämmkopf zwei Abreisszylinder 9 und 10, auf welchen je eine Abreissdruckwalze 11 bzw. 12 aufliegt, und ein Abzugwalzenpaar 13.The combing head shown schematically in FIG. 1 has a round comb roller 1 which can be rotated continuously by a drive motor (not shown) and which carries a round comb segment 2, and a pliers assembly consisting of lower pliers 3 and upper pliers 4. The lower jaw 3 is articulated at its front end to front supports 5 which can be pivoted about the axis of the circular comb roller 1 and is articulated at its rear end to tong arms 6 which sit on a tong shaft 7 which can be pivoted back and forth. The upper tongs 4 can be pivoted about an axis 8 with respect to the lower tongs 3. The combing head also has two tear-off cylinders 9 and 10, on each of which a tear-off pressure roller 11 or 12 rests, and a pair of draw-off rollers 13.

Eine zu kämmende Watte W wird von einem Watte­wickel 14, der auf zwei drehbaren Wickelwalzen 15 und 16 aufliegt, einem in der Unterzange 3 gelagerten, inter­mittierend drehbaren Speisezylinder 17 zugeführt. In einer zurückgezogenen Stellung (nicht dargestellt) des Zangenaggregates 3, 4 ist dieses geschlossen und hält einen aus dem Zangenaggregat herausragenden vorderen Endabschnitt der Watte W in Form eines Faserbartes fest. Der Faserbart wird von dem Rundkammsegment 2 auf der rotierenden Rundkammwalze 1 ausgekämmt. Anschliessend wird das Zangenaggregat 3, 4 in die dargestellte vorge­schobene, geöffnete Stellung bewegt. Die Abreisszylin­der 9 und 10 sind inzwischen durch einen vorbestimmten Winkel rückwärts gedreht worden, um den hinteren End­abschnitt des zuvor gekämmten Faserbandes F aus der Klemmstelle des Abreisszylinders 9 mit der Abreissdruck­walze 11 nach hinten (zum Zangenaggregat hin) heraus­treten zu lassen. Der vom Rundkammsegment 2 ausgekämmte Faserbart legt sich auf diesen Endabschnitt und wird mit diesem zusammen wieder in die Klemmstelle des Ab­reisszylinders 9 mit der Abreissdruckwalze 11 gezogen, wenn die Abreisszylinder 9 und 10 anschliessend vorwärts gedreht werden. Die Abreisszylinder 9 und 10 werden vor­wärts durch einen zweiten vorbestimmten Winkel gedreht, der grösser ist als der erstgenannte vorbestimmte Win­kel, z.B. etwa doppelt so gross, und sie reissen dabei den Faserbart von der im Zangenaggregat 3, 4 liegenden Watte ab. Normalerweise wird der Faserbart dabei durch einen Fixkamm hindurchgezogen, der jedoch in der Zeich­nung nicht dargestellt worden ist, um die Uebersichtlich­keit nicht zu beeinträchtigen.A cotton wool W to be combed is fed from a cotton roll 14, which rests on two rotatable winding rollers 15 and 16, to an intermittently rotatable feed cylinder 17, which is mounted in the lower tongs 3. In a retracted position (not shown) of the forceps unit 3, 4, the forceps unit 3, 4 is closed and holds a front end portion of the cotton wool W protruding from the forceps unit in the form of a fiber beard. The fiber beard is combed out by the circular comb segment 2 on the rotating circular comb roller 1. Subsequently the pliers unit 3, 4 is moved into the advanced, open position shown. The tear-off cylinders 9 and 10 have meanwhile been rotated backwards by a predetermined angle in order to allow the rear end section of the previously combed sliver F to emerge from the nip of the tear-off cylinder 9 with the tear-off pressure roller 11 to the rear (towards the pliers assembly). The combed fiber from the round comb segment 2 lies on this end section and is pulled together with this back into the nip of the tear-off cylinder 9 with the tear-off pressure roller 11 when the tear-off cylinders 9 and 10 are then rotated forward. The tear-off cylinders 9 and 10 are rotated forward by a second predetermined angle, which is greater than the first predetermined angle, for example approximately twice as large, and they tear off the fiber beard from the cotton wool lying in the pliers unit 3, 4. Normally, the fiber beard is pulled through a fixed comb, which, however, has not been shown in the drawing in order not to impair the clarity.

Die Abreisszylinder 9 und 10 müssen also in jedem Kammspiel zuerst durch einen vorbestimmten Winkel rück­wärts gedreht werden und dann durch einen anderen, grös­seren vorbestimmten Winkel vorwärts gedreht werden. Diese Bewegung wird Pilgerschrittbewegung genannt. Erfindungs­gemäss ist zum Drehen der Abreisszylinder 9 und 10 mit der beschriebenen Pilgerschrittbewegung wenigstens ein Elektromotor 18 vorgesehen, z.B. ein bürstenloser Gleich­strommotor oder ein Asynchronmotor. Der Motor 18 ist mit den Abreisszylindern 9 und 10 über ein Untersetzungsge­triebe verbunden. Dieses enthält im dargestellten Bei­spiel ein Zahnrad 19 auf der Welle des Motors 18, das über einen Zahnriemen 20 mit einem zweiten Zahnrad 21 gekuppelt ist. Auf der Welle jedes der Abreisszylinder 9 und 10 sitzt je ein Zahnrad 22 bzw. 23. Die Zahnräder 22 und 23 kämmen mit einem Ritzel 24, das auf der Welle des Zahnrads 21 sitzt.The tear-off cylinders 9 and 10 must therefore first be rotated backwards by a predetermined angle in each comb play and then rotated forward by another, larger predetermined angle. This movement is called the pilgrim step movement. According to the invention, at least one electric motor 18, for example a brushless DC motor or an asynchronous motor, is provided for rotating the tear-off cylinders 9 and 10 with the pilgrim step movement described. The motor 18 is connected to the tear-off cylinders 9 and 10 via a reduction gear. In the example shown, this contains a gearwheel 19 on the shaft of the motor 18 which is coupled to a second gearwheel 21 via a toothed belt 20. On the shaft of each of the tear-off cylinders 9 and 10 there is a gear 22 and 23, respectively. The gears 22 and 23 mesh with a pinion 24, which sits on the shaft of the gear 21.

Eine elektronische Programmsteuereinrichtung 25 führt dem Elektromotor 18 über einen Verstärker 26 elektrische Antriebsimpulse zu, so dass der Elektromo­tor 18 die Abreisszylinder 9 und 10 während jedes Kamm­spiels durch die erforderlichen Winkel dreht. Die An­triebsimpulse sind mit der Drehung der Rundkammwalze 1 synchronisiert. Zu diesem Zweck sind der Steuereinrich­tung 25 Ausgangssignale eines Drehzahlaufnehmers oder Positionsgebers 27 zugeführt, der Markierungen auf einem auf der Welle der Rundkammwalze 1 getragenen Element (nicht dargestellt) abtastet. Die Steuereinrichtung 25 kann zweckmässig einen Regler enthalten, der die abge­gebenen Antriebsimpulse so einstellt, dass die Abreiss­zylinder 9 und 10 jeweils durch die erforderlichen, vor­bestimmten Winkel gedreht werden. Als Regelgrösse sind diesem Regler Ausgangssignale eines Drehzahlaufnehmers oder Positionsgebers 28 zugeführt, der Markierungen auf einem auf der Welle des Motors 18 getragenen Element (nicht dargestellt) abtastet.An electronic program control device 25 supplies the electric motor 18 with electrical drive pulses via an amplifier 26, so that the electric motor 18 rotates the tear-off cylinders 9 and 10 through the required angles during each comb play. The drive pulses are synchronized with the rotation of the round comb roller 1. For this purpose, the control device 25 is supplied with output signals from a speed sensor or position sensor 27 which scans markings on an element (not shown) carried on the shaft of the circular comb roller 1. The control device 25 can expediently contain a controller which adjusts the emitted drive pulses in such a way that the tear-off cylinders 9 and 10 are each rotated through the required predetermined angles. As a controlled variable, output signals of a speed pickup or position sensor 28 are fed to this controller, which scans markings on an element (not shown) carried on the shaft of the motor 18.

Die Steuereinrichtung 25 und der Verstärker 26 sind von einem Stromversorgungsgerät 29 gespeist.The control device 25 and the amplifier 26 are fed by a power supply device 29.

Eine Kämmaschine enthält in der Regel mehrere in einer Reihe angeordnete Kämmköpfe von der Art des vor­stehend beschriebenen. In einer solchen Kämmaschine ist es zweckmässig, die Abreisszylinder 9 und 10 der ver­schiedenen Kämmköpfe - oder wenigstens einiger dersel­ben - durch jeweils eine gemeinsame Welle 30 bzw. 31 miteinander zu kuppeln und mit dem Elektromotor 18 über das Getriebe 19, 20, 21, 22, 23, 24 gemeinsam anzutrei­ben, wie in Fig. 2 schematisch dargestellt.A combing machine usually contains several combing heads arranged in a row of the type described above. In such a combing machine, it is expedient to couple the tear-off cylinders 9 and 10 of the various combing heads - or at least some of them - by means of a common shaft 30 and 31, respectively, and to the electric motor 18 via the gear 19, 20, 21, 22, 23, 24 to drive together, as shown schematically in FIG. 2.

In einer Variante ist es auch möglich, für die beiden Drehrichtungen der Abreisszylinder 9 und 10 an­stelle eines umsteuerbaren Motors 18 zwei getrennte Elektromotoren zu verwenden. Die Fig. 3 zeigt ähnlich wie Fig. 2 eine schematische Teildraufsicht auf die Abreisszylin­ der 9 und 10 mehrerer Kämmköpfe einer Kämmaschine. An einem Ende der gemeinsamen Wellen 30 bzw. 31 der Ab­reisszylinder 9 und 10 ist ein Elektromotor 18′ ange­ordnet, der die Abreisszylinder 9 und 10 über das Ge­triebe 19, 20, 21, 22, 23, 24 rückwärts dreht. In dem Getriebe ist zwischen den Zahnrädern 21 und 24 zusätz­liche eine Kupplung 32 angeordnet. Am anderen Ende der Wellen 30 und 31 ist ein zweiter Elektromotor 18˝ zum Vorwärtsdrehen der Abreisszylindere 9 und 10 angeordnet. Im Getriebe 19, 20, 21, 22, 23, 24 zwischen dem Motor 18˝ und den Abreisszylindern 9 und 10 ist wieder die Kupplung 32 angeordnet. Die Steuereinrichtung 25 führt den Elektromotoren 18′ und 18˝ Antriebsimpulse zu und/oder betätigt die Kupplungen 32, um die Abreiss­zylinder 9 und 10 während jedes Kammspiel durch die erforderlichen Winkel rückwärts und dann vorwärts zu drehen. Anstelle der Kupplungen 32 könnten auch Frei­läufe verwendet werden, und zwar insbesondere ent­sperrbare Freiläufe, damit jeweils der Motor 18˝ nicht mitgedreht wird, wenn der Motor 18′ die Abreisszylin­der 9 und 10 rückwärts dreht, und umgekehrt.In a variant, it is also possible to use two separate electric motors for the two directions of rotation of the tear-off cylinders 9 and 10 instead of a reversible motor 18. 3 shows, similar to FIG. 2, a schematic partial plan view of the tear-off cylinder 9 and 10 of several combing heads of a combing machine. At one end of the common shafts 30 and 31 of the tear-off cylinders 9 and 10, an electric motor 18 'is arranged, which rotates the tear-off cylinders 9 and 10 via the gear 19, 20, 21, 22, 23, 24 backwards. A clutch 32 is additionally arranged in the transmission between the gear wheels 21 and 24. At the other end of the shafts 30 and 31, a second electric motor 18˝ for rotating the tear-off cylinders 9 and 10 is arranged. In the transmission 19, 20, 21, 22, 23, 24 between the motor 18˝ and the tear-off cylinders 9 and 10, the clutch 32 is again arranged. The control device 25 leads the electric motors 18 'and 18˝ drive pulses to and / or actuates the clutches 32 in order to rotate the tear-off cylinders 9 and 10 backwards and then forwards through the required angles during each comb play. Instead of the clutches 32, freewheels could also be used, in particular unlockable freewheels, so that the motor 18˝ is not rotated when the motor 18 'rotates the tear-off cylinders 9 and 10 in reverse, and vice versa.

In einer anderen Variante treibt der umsteuer­bare Elektromotor 18 (Fig. 1, 2) über das Getriebe 19, 20, 21, 22, 24 - ohne das Zahnrad 23 auf der Welle 31 - nur die Abreisszylinder 9. Die Abreisszylinder 10 wer­den dann von einem zweiten umsteuerbaren Elektromotor (nicht dargestellt) angetrieben, der am anderen Ende der Wellen 30 und 31 angeordnet ist und über ein Unter­setzungsgetriebe (ähnlich dem Getriebe 19, 20, 21, 23, 24) mit der Welle 31 gekuppelt ist. Der Elektromotor 18 und der zweite, nicht dargestellte Elektromotor werden von der Steuereinrichtung 25 mit gleichen, syn­chronen Antriebsimpulsen gespeist.In another variant, the reversible electric motor 18 (FIGS. 1, 2) drives only the tear-off cylinders 9 via the gear 19, 20, 21, 22, 24 - without the gearwheel 23 on the shaft 31. The tear-off cylinders 10 then become one second reversible electric motor (not shown) driven, which is arranged at the other end of the shafts 30 and 31 and is coupled to the shaft 31 via a reduction gear (similar to the gear 19, 20, 21, 23, 24). The electric motor 18 and the second electric motor, not shown, are fed by the control device 25 with the same, synchronous drive pulses.
