Abstract

Two lap webs (I, II) lying one on the other are respectively fed continuously to the combing tools (1, 2, 3, 4, 5) in a plurality of combing heads of the machine. The first lap web (I) comes from a first lap roll (7) carried on a rear supporting device (8, 9) and runs over a front supporting device (11, 12). This carries a second lap roll (10), from which the second lap web (II) comes. A detector determines when the end of the lap web (I) runs off from the first lap roll (7) in one of the combing heads. A control device then executes a roll change simultaneously for a plurality of combing heads as follows: the end of the first lap web (I) is severed to the same length in all the combing heads. The severed lap-web remains and the winding tubes of the first lap rolls (7) are removed. The second lap rolls (10) are rolled onto the rear supporting devices (8, 9). New lap rolls (24) are so deposited onto the front supporting devices (11, 12) that the start (A) of the lap web of these rolls (24) is aligned with the end of the first lap web (I). The roll change can thus be carried out fully automatically and without the combing machine being stopped. <IMAGE>

Die Erfindung bezieht sich auf eine Kämmaschi­ne mit mehreren Kämmköpfen, wobei jeder Kämmkopf eine hintere Trageinrichtung mit wenigstens einer ersten an­treibbaren Wickelwalze für einen ersten Wattewickel und eine vordere Trageinrichtung mit wenigstens einer zweiten antreibbaren Wickelwalze für einen zweiten Wattewickel enthält und jedem Kämmkopf jeweils eine Transporteinrichtung zum Absetzen von Wattewickeln auf die vordere Trageinrichtung zugeordnet ist.The invention relates to a combing machine with a plurality of combing heads, wherein each combing head contains a rear carrying device with at least one first drivable winding roller for a first cotton roll and a front carrying device with at least one second drivable winding roll for a second cotton roll and each combing head has a transport device for setting down of cotton wraps is assigned to the front support device.

Ein Kammstuhl mit einem einzelnen Kämmkopf der angegebenen Art ist in der DE-B-24 34 898 beschrieben. Wenn das Watteband vom ersten Wattewickel ganz abge­wickelt ist, wird dessen leere Wickelhülse manuell ent­fernt, und der zweite Wattewickel wird von der vorderen Trageinrichtung auf die hintere Trageinrichtung ge­rollt. Dann wird die Transporteinrichtung betätigt, so dass sie einen neuen Wattewickel auf die vordere Trag­einrichtung (bzw. auf das jetzt über diese laufende Watteband vom zweiten Wattewickel) absetzt.A comb chair with a single combing head of the specified type is described in DE-B-24 34 898. When the cotton tape is completely unwound from the first cotton roll, its empty winding tube is removed manually, and the second cotton roll is rolled from the front carrier onto the rear carrier. The transport device is then actuated so that it places a new cotton wrap on the front carrying device (or on the cotton wad that is now running from the second cotton wad).

Die Aufgabe der Erfindung besteht darin, die eingangs angegebene Kämmaschine mit mehreren Kämmköpfen so auszubilden, dass es möglich ist, einen Wickelwechsel automatisch durchzuführen, und zwar auch gleichzeitig bei einigen oder allen der Kämmköpfe der Maschine.The object of the invention is to design the combing machine specified at the outset with a plurality of combing heads in such a way that it is possible to carry out a winding change automatically, and also simultaneously with some or all of the combing heads of the machine.

Die erfindungsgemässe Kämmaschine, mit der die Aufgabe gelöst wird, ist dadurch gekennzeichnet, dass jeder Kämmkopf eine Einrichtung enthält zum Durch­trennen des vom ersten Wattewickel abgewickelten, zur vorderen Trageinrichtung laufenden Wattebandes, um an einer vorbestimmten Stelle ein definiertes Ende dieses Wattebandes zu bilden, und dass eine wenigstens einigen der Kämmköpfe gemeinsam zugeordnete Steuerein­richtung zum Steuern der Einrichtungen zum Durchtrennen und der Transporteinrichtungen dieser Kämmköpfe derart vorgesehen ist, dass die Transporteinrichtungen neue Wattewickel in einem solchen Zeitpunkt auf die vorderen Trageinrichtungen absetzen, dass die Anfänge der Watte­bänder auf diesen neuen Wattewickeln auf die von den Einrichtungen zum Durchtrennen gebildeten, den vorderen Trageinrichtungen zulaufenden Watteband-Enden ausge­richtet werden.The combing machine according to the invention, with which the object is achieved, is characterized in that each combing head contains a device for severing the cotton tape, which is unwound from the first cotton roll and runs to the front carrying device, in order to form a defined end of this cotton tape at a predetermined point, and in that a control device, which is assigned to at least some of the combing heads, for controlling the devices for severing and the transport devices of these combing heads is provided in such a way that the transport devices are new Place the cotton wrap on the front support devices at such a time that the beginnings of the cotton strips on these new cotton rolls are aligned with the ends of the cotton tape formed by the severing devices and leading to the front support devices.

Die Steuereinrichtung kann zweckmässig auch Einrichtungen zum Entfernen von leeren oder fast leeren Wickelhülsen von den hinteren Trageinrichtungen und Einrichtungen zum Nachhintenrollen der zweiten Watte­wickel von den vorderen auf die hinteren Tragein­richtungen steuern.The control device can expediently also control devices for removing empty or almost empty winding sleeves from the rear carrying devices and devices for rolling the second wadding rolls backwards from the front onto the rear carrying devices.

Ein Ausführungsbeispiel der erfindungsgemäs­sen Kämmaschine wird nachstehend anhand der Zeichnungen näher erläutert. In diesen zeigen:

  • Fig. 1 einen schematischen Vertikalschnitt durch Teile eines Kämmkopfes einer Kämmaschine und
  • Fig. 2 bis Fig. 9 jeweils in kleinerem Mass­stab ähnliche Ansichten wie Fig. 1 bei anderen Stel­lungen von Teilen des Kämmkopfes.
An embodiment of the combing machine according to the invention is explained in more detail below with reference to the drawings. In these show:
  • Fig. 1 shows a schematic vertical section through parts of a combing head of a combing machine and
  • Fig. 2 to Fig. 9 each on a smaller scale similar views as Fig. 1 in other positions of parts of the combing head.

Die wesentlichen Kämmwerkzeuge des in Fig. 1 schematisch dargestellten Kämmkopfes sind ein dreh­barer Rundkamm 1, ein Fixkamm 2, zwei Abreisszylinder 3 und ein Zangenaggregat mit einer Unterzange 4 und einer bezüglich der Unterzange schwenkbaren Oberzange 5. In der Unterzange 4 ist ein intermittierend antreib­barer Speisezylinder 6 gelagert.The essential combing tools of the combing head shown schematically in FIG. 1 are a rotatable circular comb 1, a fixed comb 2, two tear-off cylinders 3 and a pair of pliers with a pair of lower pliers 4 and an upper plier 5 which can be pivoted with respect to the lower pliers 5 stored.

Dem Speisezylinder 6 werden zwei parallel aufeinanderliegende Wattebänder I und II zugeführt. Das Watteband I wird von einem ersten Wattewickel 7 abgewickelt, der auf einer hinteren Trageinrichtung getragen ist. Die hintere Trageinrichtung besteht aus zwei parallelen Wickelwalzen 8 und 9, von denen wenig­stens eine antreibbar ist. Das Watteband II wird von einem zweiten Wattewickel 10 abgewickelt, der auf einer vorderen Trageinrichtung getragen ist. Die vorde­re Trageinrichtung besteht wieder aus zwei Wickelwalzen 11 und 12, die zueinander und zu den Wickelwalzen 8 und 9 parallel sind. Wenigstens eine der Wickelwalzen 11 und 12 ist antreibbar. Das erste Watteband I läuft da­bei über die vordere Trageinrichtung, d.h. über die Wickelwalzen 11 und 12, und der zweite Wattewickel 10 liegt über der vorderen Trageinrichtung auf dem ersten Watteband I.The feed cylinder 6 is supplied with two cotton bands I and II lying parallel to one another. The cotton tape I is unwound from a first cotton roll 7, which is carried on a rear support device. The rear support device consists of two parallel winding rollers 8 and 9, at least one of which can be driven. The cotton tape II is unwound from a second cotton roll 10, which on a front support device is worn. The front support device again consists of two winding rollers 11 and 12, which are parallel to each other and to the winding rollers 8 and 9. At least one of the winding rollers 11 and 12 can be driven. The first cotton band I runs over the front carrier device, ie over the winding rollers 11 and 12, and the second cotton roll 10 lies over the front carrier device on the first cotton band I.

Die Kämmaschine enthält mehrere, z.B. acht, in einer Reihe angeordnete Kämmköpfe von der Art des beschriebenen. Wenn in einem der Kämmköpfe der Maschine das Watteband I vom ersten Wattewickel 7 wenigstens an­nähernd vollständig abgewickelt ist, dann wird automa­tisch und ohne Abstellen der Kämmaschine ein Wickel­wechsel durchgeführt, und zwar gleichzeitig bei allen Kämmköpfen der Maschine oder wenigstens bei einer Grup­pe der Kämmköpfe, z.B. bei vier Kämmköpfen.The combing machine contains several, e.g. eight comb heads of the type described, arranged in a row. If in one of the combing heads of the machine the cotton tape I is at least almost completely unwound from the first wadding roll 7, then a winding change is carried out automatically and without switching off the combing machine, simultaneously with all combing heads of the machine or at least with one group of combing heads, e.g. with four combing heads.

Jeder Kämmkopf enthält zu diesem Zweck einen Detektor (nicht dargestellt), der z.B. den in Fig. 2 dargestellten Zeitpunkt feststellt, in welchem auf der Wickelhülse des ersten Wattewickels 7 das Ende E des ersten Wattebandes I erscheint. Dieser Detektor kann beispielsweise eine Fotozelle sein, die den Hellig­keitsunterschied zwischen dem helleren Watteband und der dunkleren Wickelhülse des Wattewickels 7 erkennt. Der Detektor gibt ein Signal ab, das eine Programmsteuer­einrichtung (nicht dargestellt) startet, welche dann bei allen Kämmköpfen der Maschine oder wenigstens bei einer Gruppe der Kämmköpfe gleichzeitig die nachstehend beschriebenen Vorgänge bewirkt.For this purpose, each combing head contains a detector (not shown) which e.g. 2 determines the time at which the end E of the first cotton tape I appears on the winding tube of the first cotton roll 7. This detector can, for example, be a photocell that detects the difference in brightness between the lighter cotton tape and the darker winding tube of the cotton roll 7. The detector emits a signal which starts a program control device (not shown) which then simultaneously effects the operations described below in all combing heads of the machine or at least in one group of the combing heads.

Zuerst wird eine Einrichtung zum Entfernen der leeren oder fast leeren Wickelhülse des ersten Wattewickels 7 von der hinteren Trageinrichtung 8, 9 betätigt. Diese Einrichtung enthält beispielsweise eine Einrichtung zum Verlagern der hinteren Wickelwalze 9 in die in Fig. 2 mit einer unterbrochenen Linie angedeute­te Stellung, etwa eine Einrichtung 13 (Fig. 1) zum Ver­schwenken von die hintere Wickelwalze 9 tragenden Armen 14. Durch diese Verlagerung wird der Abstand zwischen den Wickelwalzen 8 und 9 so weit vergrössert, dass die leere oder fast leere Wickelhülse zwischen den beiden Wickelwalzen hindurch nach unten fällt. Unter den Wickelwalzen 8 und 9 ist zweckmässig eine Führung 15 angeordnet, auf der die Wickelhülse dann nach hinten rollt. Dabei wickelt sich der auf der Wickelhülse ver­bliebene Watterest - der natürlich in den verschiedenen Kämmköpfen etwas unterschiedliche Längen haben wird - ab und bleibt auf der Führung 15 liegen. Die leere Wickelhülse rollt auf eine Auffangschale 16, wie in Fig. 3 gezeigt.First, a device for removing the empty or almost empty winding tube of the first cotton roll 7 from the rear support device 8, 9 is actuated. This facility contains, for example A device for moving the rear winding roller 9 into the position indicated by a broken line in FIG. 2, for example a device 13 (FIG. 1) for pivoting arms 14 carrying the rear winding roller 9. This displacement makes the distance between the winding rollers 8 and 9 enlarged to such an extent that the empty or almost empty winding tube falls down between the two winding rollers. A guide 15 is expediently arranged under the winding rollers 8 and 9, on which the winding tube then rolls backwards. The cotton residue remaining on the winding tube - which will of course have slightly different lengths in the different combing heads - unwinds and remains on the guide 15. The empty winding tube rolls onto a collecting tray 16, as shown in FIG. 3.

Dann wird in den Kämmköpfen eine Einrichtung zum Durchtrennen des Wattebandes I an einer vorbestimm­ten Stelle betätigt. Damit sollen die auf den Führungen 15 liegenden, in den verschiedenen Kämmköpfen unter­schiedlich langen Wattereste abgetrennt werden und ein definiertes Ende des Wattebandes I gebildet werden, das in allen Kämmköpfen an der gleichen vorbestimmten Stelle liegt. Die Einrichtung zum Durchtrennen kann beispiels­weise Mittel enthalten zum Andrücken des Wattebandes I an die angetriebene Wickelwalze 8, so dass diese das Watteband I weiterbewegt, und Mittel zum Festhalten des Wattebandes I unmittelbar hinter der Wickelwalze 8, so dass das Watteband hier reisst. Die Mittel zum Andrücken des Wattebandes I an die Wickelwalze 8 können Mittel enthalten, um die Wickelwalze 9 wie in Fig. 4 gezeigt gegen die Wickelwalze 8 zu bewegen, z.B. die schon erwähnte Einrichtung 13 (Fig. 1) mit den Schwenk­armen 14. Die Schwenkarme 14 können gleichzeitig eine Zangenschiene 17 tragen, die mit einer feststehenden, z.B. an der Führung 15 angebrachten Zangenschiene 18 zu­sammenwirkt, um das Watteband I hinter der Wickelwalze 8 festzuklemmen. Das von den Wickelwalzen 8 und 9 weiterbewegte Watteband I reisst dann zwischen diesen und den Zangenschienen 17, 18, und es entsteht ein neues, definiertes Ende E.1 des Wattebandes I.Then in the combing heads a device for cutting the cotton tape I is operated at a predetermined point. Thus, the cotton residues lying on the guides 15 and of different lengths in the various combing heads are to be separated and a defined end of the cotton tape I is to be formed, which lies in the same predetermined position in all combing heads. The device for severing can contain, for example, means for pressing the cotton tape I against the driven winding roller 8 so that it moves the cotton tape I further, and means for holding the cotton tape I directly behind the winding roller 8 so that the cotton tape tears here. The means for pressing the cotton tape I against the winding roller 8 can include means for moving the winding roller 9 against the winding roller 8 as shown in FIG. 4, for example the already mentioned device 13 (FIG. 1) with the swivel arms 14. The swivel arms 14 can at the same time carry a clamp rail 17 which is connected to a fixed, For example, pliers rail 18 attached to the guide 15 cooperate in order to clamp the cotton tape I behind the winding roller 8. The cotton tape I moved on by the winding rollers 8 and 9 then tears between them and the tong rails 17, 18, and a new, defined end E.1 of the cotton tape I is created.

Wenn zum Durchtrennen des Wattebandes I die Wickelwalze 9 wie beschrieben verlagert worden ist, dann wird diese anschliessend wieder in ihre Ausgangs­stellung zurückverbracht, und die Zange 17, 18 wird geöffnet.If the winding roller 9 has been moved as described to cut the cotton tape I, it is then returned to its starting position and the pliers 17, 18 are opened.

Dann wird eine Einrichtung zum Entfernen des abgetrennten hinteren Endabschnittes des Wattebandes I von der Führung 15 betätigt. Beispielsweise mündet in die Führung 15 von unten ein Absaugkanal 19, in welchem ein Unterdruck erzeugt wird, wie in Fig. 5 angedeutet.Then, a device for removing the separated rear end portion of the cotton tape I from the guide 15 is operated. For example, a suction channel 19 opens into the guide 15 from below, in which a negative pressure is generated, as indicated in FIG. 5.

Ferner wird eine Einrichtung betätigt, welche den zweiten Wattewickel 10 von der vorderen Tragein­richtung 11, 12 nach hinten auf die hintere Trageinrich­tung 8, 9 verbringt. Diese Einrichtung enthält bei­spielsweise einen Stössel 20, der den Wattewickel 10 nach hinten stösst, so dass dieser auf dem (von einer Führung 21 unterstützten) Watteband I in die in Fig. 6 gezeigte Stellung rollt.Furthermore, a device is actuated, which brings the second wad of cotton 10 backwards from the front carrying device 11, 12 onto the rear carrying device 8, 9. This device contains, for example, a plunger 20, which pushes the cotton roll 10 backwards, so that it rolls on the cotton tape I (supported by a guide 21) into the position shown in FIG. 6.

Jedem Kämmkopf ist eine Transporteinrichtung zum Absetzen von neuen Wattewickeln auf die vordere Trageinrichtung 11, 12 zugeordnet. Von dieser Transport­einrichtung ist nur ein Tragarm 22 mit einem Zapfen 23 in den Fig. 1 und 7 dargestellt. Die Transporteinrich­tung 22, 23 wird nun betätigt, um einen neuen Watte­wickel 24 auf die Wattebänder I und II zu setzen, die über die Wickelwalzen 11 und 12 der vorderen Tragein­richtung laufen. Der Anfang A des Wattebandes auf dem neuen Wattewickel 24 ist auf dem Umfang dieses Wickels so positioniert, dass dieser Anfang A im Zeitpunkt des Aufsetzen des Wickels 24 auf die vordere Trageinrichtung den gleichen Abstand von der Wickelwalze 12 hat wie das Ende E.1 des ersten Wattebandes I. Da der neue Wattewickel 24 nach dem Aufsetzen auf die Wickelwalzen 11, 12 mit denselben gedreht wird, erreichen daher der Anfang A und das Ende E.1 die Wickelwalze 12 gleich­zeitig, das heisst, der Anfang A und das Ende E.1 wer­den miteinander ausgerichtet.Each combing head is assigned a transport device for depositing new cotton bobbins on the front carrying device 11, 12. Of this transport device, only one support arm 22 with a pin 23 is shown in FIGS. 1 and 7. The transport device 22, 23 is now actuated in order to place a new cotton roll 24 on the cotton bands I and II, which run over the winding rollers 11 and 12 of the front carrying device. The start A of the cotton tape on the new cotton roll 24 is positioned on the circumference of this roll so that this start A at the time of Placing the winding 24 on the front support device is at the same distance from the winding roller 12 as the end E.1 of the first cotton tape I. Since the new cotton winding 24 is rotated with the same after being placed on the winding rollers 11, 12, the beginning is reached A and the end E.1, the winding roller 12 at the same time, that is, the start A and the end E.1 are aligned with each other.

Die Fig. 8 zeigt einen Zustand, wie er auf­treten kann, nachdem der Anfang A und das Ende E.1 die Wickelwalze 11 verlassen haben. Der Anfang A haftet möglicherweise am Umfang des neuen Wickels 24. Daher wird nun eine Ablöseeinrichtung zum Ablösen des Anfangs A vom Umfang des Wickels 24 betätigt. Die Ablöseein­richtung ist beispielsweise eine Saugdüse 25, die zum Umfang des Wattewickels 24 hin bewegt wird, um den An­fang A abzulösen. Anschliessend wird die Saugdüse 25 wieder zurückgezogen und der Unterdruck abgestellt, so dass sich der Anfang A wie in Fig. 9 gezeigt auf das vom Wattewickel 10 kommende Watteband II legt. Anstelle der Saugdüse 25 könnte natürlich auch eine Saugwalze oder ein mechanisches Element verwendet werden, um den Anfang A vom Umfang des neuen Wattewickels 24 zu lösen und auf das Watteband II aufzulegen.FIG. 8 shows a state as it can occur after the start A and the end E.1 have left the winding roller 11. The start A may adhere to the circumference of the new roll 24. Therefore, a detaching device for detaching the start A from the circumference of the roll 24 is actuated. The detaching device is, for example, a suction nozzle 25, which is moved toward the circumference of the cotton roll 24 in order to detach the start A. The suction nozzle 25 is then withdrawn again and the negative pressure is switched off, so that the start A, as shown in FIG. 9, lies on the cotton tape II coming from the cotton roll 10. Instead of the suction nozzle 25, a suction roller or a mechanical element could of course also be used in order to detach the beginning A from the circumference of the new wadding roll 24 and to place it on the wadding band II.

Der auf dem Watteband II liegende Anfang A des Wattebandes vom neuen Wattewickel 24 läuft dann zusammen mit dem Watteband II durch ein Presswalzen­paar 26, welches den Anfang A auf das Band II presst.The start A of the cotton tape from the new cotton roll 24 lying on the cotton tape II then runs together with the cotton tape II through a pair of press rollers 26 which presses the start A onto the tape II.

Man sieht, dass in der beschriebenen Kämma­schine dem Speisezylinder 6 jedes Kämmkopfes stets zwei aufeinanderliegende Wattebänder zugeführt werden. Da beim automatisch und bei laufender Maschine durchge­führten Wickelwechsel der Anfang A des Wattebandes vom neuen Wattewickel 24 auf das Ende E.1 des Wattebandes I vom ersten Wickel 7 ausgerichtet wird, entsteht beim Uebergang weder eine Verdickung noch eine Stelle mit reduzierter Dicke.It can be seen that in the combing machine described the feed cylinder 6 of each combing head is always fed two cotton strips lying one on top of the other. Since the start A of the cotton tape from the new cotton roll 24 is aligned with the end E.1 of the cotton tape I from the first roll 7 when the roll change is carried out automatically and with the machine running, this results in There was no thickening or a reduced thickness area.

Die leere Wickelhülse vom ursprünglichen ersten Wattewickel 7 liegt in Fig. 9 immer noch auf der Auffangschale 16. Diese Wickelhülse wird, gesteuert von der Steuereinrichtung, in einem passenden Zeitpunkt an die Transporteinrichtung zurückgegeben bzw. von dieser übernommen.In FIG. 9, the empty winding tube from the original first cotton roll 7 is still on the collecting tray 16. This winding tube, controlled by the control device, is returned to the transport device at a suitable point in time or taken over by the latter.
