Description

Die Erfindung betrifft ein Verfahren wie dies im Oberbegriff des ersten Anspruches und eine Vorrichtung wie dies im Oberbegriff des siebten Anspruches beschrieben ist.The invention relates to a method as described in the preamble of the first claim and a device as described in the preamble of the seventh claim.

Wattewickel dienen als Vorlagen für die Kehrstrecke und den nachfolgenden Kammprozess.Cotton wraps serve as templates for the sweeping section and the subsequent combing process.

Zwei wesentliche Ziele beim Bilden von Wattewickeln sind einerseits das Erreichen eines hohen spezifischen Gewichtes und andererseits das problemlose Wiederabrollen des Wattewickels, d. h. das Vermeiden einer gegenseitigen Verflechtung der im Wickel aufeinanderliegenden Wattebahnen.Two essential goals in the formation of cotton rolls are on the one hand the achievement of a high specific weight and on the other hand the problem-free unrolling of the cotton roll, i. H. avoiding the interweaving of the cotton sheets lying one on top of the other in the winding.

Um auf diese zwei Ziele hin zu arbeiten werden die Wattebahnen vor dem Bilden des Wattewickels sogenannt kalandriert, d. h. die Wattebahn wird fortlaufend zwei bis dreimal zwischen Kalanderwalzen gepresst und in kleinem Masse verstreckt, sodass eine Verdichtung der Wattebahn stattfindet.In order to work towards these two goals, the cotton webs are so-called calendered before the cotton roll is formed, i. H. the cotton web is continuously pressed between calender rolls two to three times and stretched to a small extent so that the cotton web is compressed.

In den an sich bekannten Anordnungen liegt zwischen dem letzten Kalanderwalzenpaar und dem zu bildenden Wattewickel die Wattebahn entweder frei auf einer der beiden Wickelwalzen oder hängt frei, d. h. ungestützt in der Luft, d. h. lediglich durch die Klemmstelle des letzten Kalanderpaares und durch die Klemmstelle zwischen Wattewickel und Wickelwalze gehalten.In the arrangements known per se, between the last pair of calender rolls and the wadding roll to be formed, the wadding web is either freely on one of the two winding rolls or hangs freely; H. unsupported in the air, d. H. held only by the nip of the last pair of calenders and by the nip between the cotton roll and the winding roller.

Dies bringt den wesentlichen Nachteil, dass die Wattebahn nach dem Kalandrieren wieder "aufatmet", wodurch die Dicke der Wattebahn wieder vergrössert wird.This has the major disadvantage that the cotton web "breathes again" after calendering, which increases the thickness of the cotton web again.

Die GB Patentschrift No. 1 150 651 zeigt zwischen dem letzten Kalanderwalzenpaar und der ersten Wickelwalze, in Laufrichtung der Wattebahn gesehen, eine Antriebswalze, welche die Wattebahn gegen eine feste Führungsplatte drückt: Die Funktion dieser beiden letztgenannten Elemente besteht darin, daß beim Reissen der Wattebahn vor dem Doffen des Watterwickels, wobei die Wickelwalzen vor dem Doffen gegenüber der normalen Drehzahl beschleunigt werden, die Wattebahn im Klemmspalt der vorgenannten beiden Klemmelemente sauber reisst.GB Patent No. 1 150 651 shows between the last pair of calenders and the first winding roller, seen in the running direction of the wadding web, a drive roller which presses the wadding web against a fixed guide plate: the function of these two latter elements is that when the wadding web is torn before the wadding roll is doffed , the winding rollers being accelerated before doffing compared to the normal speed, the cotton web tears cleanly in the nip of the aforementioned two clamping elements.

Das vorgenannte Klemmen der Wattebahn verhindert jedoch das vorgenannte "Aufatmen" nicht eigentlich, da die Klemmstelle immer noch in einer zu grossen Distanz zum Wattewickel vorgesehen ist und in dieser Anordnung auch nicht in den Zwickelspalt zwischen dem Wattewickel und der ersten Wickelwalze gebracht werden kann.The aforementioned clamping of the cotton wool web does not, however, actually prevent the aforementioned "breathing deeply", since the clamping point is still provided too far from the cotton lap and, in this arrangement, cannot be brought into the gusset gap between the cotton lap and the first winding roller.

Dieser Stand der Technik verhindert deshalb das vorgenannte Aufatmen in einem nur ganz eingeschränkten und nicht kontrollierbaren Masse.This prior art therefore prevents the aforementioned sighing in to a very limited and uncontrollable extent.

Die GB Patentschri ft No 680 464 zeigt eine Wattewickelvorrichtung, in welcher der Wattewickel in einem angetriebenen, den Wattewickel im wesentlichen umfassenden Förderband aufgenommen und im wesentlichen eingeschlossen ist.GB Patent Specification No. 680 464 shows a cotton winding device in which the cotton roll is received and essentially enclosed in a driven conveyor belt which essentially comprises the cotton roll.

Durch die Anpresskraft des Wattewickels auf dem Förderband entsteht am Wattewickel selbst eine laufende, der spezifischen Flächenpressung entsprechende Verdichtung am ganzen Umfange des Wattewickels.The pressing force of the cotton roll on the conveyor belt results in a continuous compression on the entire length of the cotton roll corresponding to the specific surface pressure.

Der Nachteil dieses Systems besteht jedoch darin, dass nicht nur die äusserste Lage, sondern der ganze Wickel am ganzen Umfangsteil des Förderbandes gepresst wird, so dass die einzelnen Lagen ebenfalls ineinandergepresst werden.The disadvantage of this system, however, is that not only the outermost layer, but the entire winding is pressed on the entire circumferential part of the conveyor belt, so that the individual layers are also pressed into one another.

Es wurde jedoch früher erwähnt, dass das eine Ziel beim Bilden von Wattewickeln darin besteht, dass das gegenseitige Verflechten der Wickel auf einanderliegenden Wattebahnen möglichst vermieden werden soll. Der letztgenannte Stand der Technik wirkt diesem Ziel entgegen.However, it was mentioned earlier that the one goal when forming cotton rolls is that the mutual interweaving of the rolls on mutually lying cotton sheets should be avoided as far as possible. The latter state of the art counteracts this goal.

Erfindungsgemäss wird das "Wiederaufatmen" der Wattebahn vor dem Bilden des Wattewickels durch die im Kennzeichen des 1. Verfahrensanspruches erwähnten Verfahrensschritte und durch die im Kennzeichen des 1. Vorrichtungsanspruches erwähnten Mittel im wesentlichen unterdrückt.According to the invention, the "re-breathing" of the cotton web before the wadding is formed is substantially suppressed by the method steps mentioned in the characterizing part of the first method claim and by the means mentioned in the characterizing part of the first device claim.

Die weiteren vorteilhaften Verfahrensschritte sind in den weiteren Verfahrensansprüchen und die weiteren vorteilhaften Ausführungsformen in den weiteren Vorrichtungsansprüchen beschrieben. Ein Vorteil der Erfindung besteht grundsätzlich darin, dass die Wattebahn kurz vor dem Bilden des Wattewickels nochmals verdichtet wird.The further advantageous method steps are described in the further method claims and the further advantageous embodiments in the further device claims. An advantage of the invention is basically that the cotton web is compacted again shortly before the cotton lap is formed.

Ein in dieser Richtung erweiterter Vorteil besteht in der Möglichkeit, die Glättekante mit dem Zwickelbereich derart wandern zu lassen, dass die Verdichtung der Wattebahn auch bei grösser werden dem Wattewickel immer in unmittelbarer Nähe des Zwickelbereiches liegt.An advantage extended in this direction is the possibility of allowing the smooth edge to migrate with the gusset area in such a way that the compression of the batting is always in the immediate vicinity of the gusset area, even when the batting is larger.

Ein weiterer Vorteil der Erfindung besteht darin, dass die Funktion des Verdichtens der Wattebahn mit der Funktion des Produzierens einer Wirrlage der obersten Faserschicht der Wattebahn kombiniert werden kann. Besonders vorteilhaft ist in dieser Beziehung die Kombination einer ersten, mit Zähnen versehenen Glättekante mit einer zweiten lediglich eine gerade Biegekante oder einen Wulst aufweisenden Glättekante.Another advantage of the invention is that the function of compacting the cotton web can be combined with the function of producing a tangle of the top fiber layer of the cotton web. In this respect, it is particularly advantageous to combine a first smoothing edge provided with teeth with a second smoothing edge which has only a straight bending edge or a bead.

Dabei kann der Vorteil des Bildens einer Wirrlage der obersten Faserschicht so erklärt werden, dass sich ohne diese Wirrlage die im wesentlichen parallelisierten Fasern der Wattebahn beim Bilden des Wattewickels eher ineinander verflechten als wenn die oberste Faserschicht eine Wirrlage aufweist. Anders erklärt erzeugt diese Wirrlage der obersten Faserschicht einen ähnlichen Effekt und ähnlichen Vorteil wie das Bilden einer Kreuzspule gegenüber dem Bilden einer Spule mit Parallelwicklung.The advantage of forming a tangle of the uppermost fiber layer can be explained in such a way that without this tangle the essentially parallelized fibers of the cotton web intertwine with one another when the cotton roll is formed than if the top fiber layer has a tangle. In other words, this confusion of the top fiber layer produces a similar effect and advantage as the formation of a cheese over the formation of a coil with a parallel winding.

Ein Wickelapparat 1 (Figur 1) umfasst eine erste Wickelwalze 2 und eine zweite Wickelwalze 3 zur Aufnahme einer Wickelhülse 4, respektive des auf die Wickelhülse 4 aufgenommenen Wickels 5.A winding apparatus 1 (FIG. 1) comprises a first winding roller 2 and a second winding roller 3 for receiving a winding tube 4, or respectively the winding 5 received on the winding tube 4.

Vor der ersten Wickelwalze 2 sind Kalanderwalzen 6 angeordnet, zur Verdichtung einer in Pfeilrichtung F geförderten Wattebahn 7. Nach der letzten Kalanderwalze, in Förderrichtung F gesehen, wird die Wattebahn 7 auf die erste Wickelwalze 2 und anschliessend von dieser auf die Wickelhülse 4 respektive auf den Wattewickel 5 abgegeben.Calender rollers 6 are arranged in front of the first winding roller 2, for compacting a cotton web 7 conveyed in the direction of arrow F. After the last calender roller, seen in the direction of conveyance F, the cotton web 7 is placed on the first winding roller 2 and subsequently on the winding tube 4 or on the winding tube 4 Cotton wrap 5 delivered.

Ein nach der letzten Kalanderwalze 6 vorgesehenes Glätteblech 8 glättet die auf der ersten Wickelwalze 2 aufliegende Wattebahn 7 unmittelbar vor dem Aufnehmen durch die Hülse 4 respektive durch den Wattewickel 5 derart, dass die durch das, nach den Kalanderwalzen 6 stattfindende, sogenannte "Atmen" der Wattebahn vergrösserte Dicke der Wattebahn für das Bilden des Wattewickels wieder reduziert wird.A smoothing sheet 8 provided after the last calender roll 6 smoothes the cotton web 7 lying on the first winding roll 2 immediately before being picked up by the sleeve 4 or by the cotton roll 5 in such a way that the so-called "breathing" of the calender rolls 6 takes place Cotton web increased thickness of the cotton web for forming the cotton roll is reduced again.

Dadurch erfährt die Wattebahn unmittelbar vor dem Bilden des Wattewickels die für die Erhöhung des spezifischen Wickelgewichtes erwünschte erhöhte Verdichtung.As a result, the cotton web experiences the increased compression desired for increasing the specific winding weight immediately before the cotton lap is formed.

Wie mit den Figuren 10 und 11 gezeigt, besteht dass Glätteblech 8 aus einer federnden Zunge 9, deren hinteres Ende 10, in Förderrichtung F der Wattebahn 7 gesehen, um eine Welle 11 gerollt und mit dieser Welle fest verbunden ist.As shown in FIGS. 10 and 11, the smoothing plate 8 consists of a resilient tongue 9, the rear end 10 of which, viewed in the conveying direction F of the cotton web 7, is rolled around a shaft 11 and is firmly connected to this shaft.

Das vordere Ende 12, auch Glättekante genannt, der Zunge 9 weist eine auf die Wattebahn 7 hin gerichtete Biegekante 13 auf. Diese Biegekante wird mit der Federkraft der Zunge 9, zur Erzeugung der genannten Verdichtung, in die Wattebahn 7 gedrückt.The front end 12, also called the smooth edge, of the tongue 9 has a bending edge 13 directed towards the batting 7. This bending edge is pressed into the wadding web 7 with the spring force of the tongue 9 to produce the compression mentioned.

Die Welle 11 ist an beiden Enden je in einem Schwenkarm 14, respektive 15 drehbar gelagert und je mit einem Schwenkhebel 16, respektive 17 fest verbunden. Die Schwenkhebel 16 und 17 weisen je einen Schlitz 18 auf, durch welchen je eine Schraube 19 ragt, deren Gewinde 20 im Arm 14, respektive 15 aufgenommen ist.The shaft 11 is rotatably supported at both ends in a swivel arm 14 or 15 and each is fixedly connected to a swivel lever 16 or 17. The pivot levers 16 and 17 each have a slot 18 through which a screw 19 projects, the thread 20 of which is received in the arm 14 and 15, respectively.

Mittels dieser Schraube 19 wird der Schwenkhebel 16, respektive 17 in einer gewünschten Position festgehalten, wobei die wählbaren Positionen durch die Länge des Schlitzes 18 begrenzt sind. Die Veränderung dieser Position bewirkt eine Veränderung der Federkraft der Zunge 9.The pivot lever 16 or 17 is held in a desired position by means of this screw 19, the selectable positions being limited by the length of the slot 18. The change in this position causes a change in the spring force of the tongue 9.

Die beiden Schwenkarme 14 und 15 sind je mit einer Büchse 21, repsektive 22 fest verbunden, die ihrerseits drehbar auf einer zur ersten Wickelwalze 2 gehörenden Welle 23 gelagert ist.The two swivel arms 14 and 15 are each firmly connected to a bushing 21, 22, which in turn is rotatably mounted on a shaft 23 belonging to the first winding roller 2.

Zur Betätigung dieser Schwenkarme 14, respektive 15 ist mit der Büchse 21, respektive 22 ein Kraftübertragungshebel 24, respektive 25 fest verbunden. Dabei ist der Kraftübertragungshebel 24 auf einer zu einem Tragarm 26 gehörenden Rolle 28 und der Kraftübertragungshebel 25 auf einer zu einem Tragarm 27 gehörenden Rolle 29 abgestützt.To actuate these swivel arms 14 or 15, a force transmission lever 24 or 25 is fixedly connected to the bushing 21 or 22. The force transmission lever 24 is supported on a roller 28 belonging to a support arm 26 and the force transmission lever 25 is supported on a roller 29 belonging to a support arm 27.

Die Tragarme 26 und 27 dienen der Aufnahme der Wickelhülse 4, respektive des Wickels 5 wozu der Tragarm 26, respektive 27 an seinem Kopfteil mit einem Pneumatikzylinder 30 (Fig. 4), respektive 31 und einer am Pneumatikzylinder 30, respektive 31 konzentrisch dazu befestigten Wickelbegrenzungsscheibe 32, respektive 33 (Figur 4, in Figur 1 der Übersichthalber nicht dargestellt) versehen ist. Zum Festhalten der Wickelhülse 4 schiebt sich der Kolben (nicht gezeigt) des Pneumatikzylinders 30, respektive 31 in die Wickelhülse.The support arms 26 and 27 serve to receive the winding tube 4, or the winding 5, for which purpose the support arm 26, or 27 on its head part with a pneumatic cylinder 30 (FIG. 4), respectively 31 and a winding limiting disc fixed to the pneumatic cylinder 30, respectively 31 32 or 33 (FIG. 4, not shown in FIG. 1 for the sake of clarity). To hold the winding tube 4 in place, the piston (not shown) of the pneumatic cylinder 30 or 31 is pushed into the winding tube.

Die Rolle 28 resp. 29 gehört insofern zum Tragarm 26 resp. 27, als sie auf der, der Wickelbegrenzungsscheibe 32 (Fig. 4, 7 und 7a), respektive 33 gegenüber liegenden Rückseite 34, respektive 35 des Pneumatikzylinders 30, respektive 31 befestigt ist.The role 28 resp. 29 belongs to the support arm 26 or. 27 when it is fastened on the rear side 34, respectively 35 of the pneumatic cylinder 30, respectively 31, which is opposite the winding limiting disk 32 (FIGS. 4, 7 and 7a) or 33.

Die Tragarme 26 und 27 sind je an ihrem Kopfteil schwenkbar mit einem Gleitelement 36 (nur für einen Tragarm gezeigt) verbunden, welches durch eine Gleitschiene 37 geführt ist. Die Gleitschiene 37 selbst ist an beiden Enden mittels Träger 38, respektive 39 je weils an einer zum Wickelapparat gehörenden Seitenwand 40 (Figur 4), respektive 41 befestigt (nicht gezeigt).The support arms 26 and 27 are each pivotally connected at their head part to a slide element 36 (shown only for one support arm) which is guided by a slide rail 37. The slide rail 37 itself is fastened at both ends by means of supports 38 and 39 respectively to a side wall 40 (FIG. 4) and 41 belonging to the winding apparatus (not shown).

Die Tragarme 26 und 27 sind an ihrem Fussteil mittels einer Schwenkachse 42 schwenkbar mit einem Schwenkmechanismus 44 verbunden, welcher seinerseits mittels Schwenkachsen 43 in zur Seitenwand 40, respektive 41 gehörenden Lagerkörpern 60, schwenkbar angeordnet ist. Ein Mittelteil 45 des Schwenkmechanismus ist ebenfalls schwenkbar mit einer Kolbenstange 46 eines schwenkbaren, an einem stationären Support 59 befestigten Pneumatikzylinders 47 verbunden.The support arms 26 and 27 are pivotally connected at their foot part by means of a pivot axis 42 to a pivot mechanism 44, which in turn is pivotably arranged by means of pivot axes 43 in bearing bodies 60 belonging to the side wall 40 and 41, respectively. A middle part 45 of the pivot mechanism is also pivotally connected to a piston rod 46 of a pivotable pneumatic cylinder 47 fastened to a stationary support 59.

Im Betrieb, d. h. beim Aufbau des Wickels 5 steuert eine nicht gezeigte und nicht zur Erfindung gehörende in der Schweizer Patentanmeldung Nr. 5561/83-3 des Anmelder gezeigten und beschriebenen Steuerung den Pneumatikzylinder 47 derart, dass die Tragarme 26 und 27 und damit die Wickelhülse 4 aus der in Figur 1 gezeigten Ausgangsposition (mit vollen Linien dargestellt) allmählich in die Endposition (mit strichpunktierten Linien dargestellt) bewegt werden. Durch diese Bewegung werden die Kraftübertragungshebel 24 und 25 und damit zwangsläufig die Schwenkarme 14 und 15, respektive das Glätteblech 8 aus der Ausgangsposition (mit vollen Linien dargestellt) in die Endposition (mit strichpunktierten Linien dargestellt) zurück versetzt.In operation, d. H. in the construction of the winding 5, a control (not shown and not part of the invention) shown and described in the applicant's Swiss patent application No. 5561 / 83-3 controls the pneumatic cylinder 47 in such a way that the support arms 26 and 27 and thus the winding tube 4 from the in Figure 1 shown starting position (shown with solid lines) are gradually moved to the end position (shown with dash-dotted lines). As a result of this movement, the force transmission levers 24 and 25 and thus inevitably the swivel arms 14 and 15 or the smoothing plate 8 are moved back from the starting position (shown with full lines) to the end position (shown with dash-dotted lines).

Um nun diese Bewegung des Glättebleches 8 derart zu gestalten, dass beim Grösserwerdendes Wickels 5 das vordere Ende 12 des Glättebleches 8 in einem Abstand von nur wenigen Zentimetern, beispielsweise von 2 cm, zum Wickelumfang bleibt, sind die auf den Rollen 28 und 29 auf liegenden Steuerflächen 48 der Kraftübertragungshebel 24, respektive 25 entsprechend mit einer in den Figuren 1 und 7 gezeigten Krümmung versehen. Das Mass und der Verlauf der Krümmung muss dabei je nach Konstruktion der Maschine von Fall zu Fall bestimmt werden, wobei unter Verlauf der Krümmung die Veränderung des Biegeradius (Fig. 1) der Steuerfläche 48 von der mit dem Riegeradius r1 gekennzeichneten Ausgangslage bis zu der mit dem Biegeradius r2 gekennzeichneten Endlage der Rolle 28, respektive 29 verstanden werden soll.In order to design this movement of the smoothing plate 8 in such a way that when the winding 5 grows, the front end 12 of the smoothing plate 8 remains at a distance of only a few centimeters, for example 2 cm, from the circumference of the winding, which are on the rollers 28 and 29 Control surfaces 48 of the power transmission levers 24 and 25 respectively are correspondingly provided with a curvature shown in FIGS. 1 and 7. The size and the course of the curvature must be determined from case to case, depending on the design of the machine, with the change in the bending radius (FIG. 1) of the control surface 48 from the starting position marked with the bending radius r1 to the position with the course of the curvature the bend radius r2 marked end position of the roll 28 or 29 should be understood.

Letztlich ist die Welle 23 in einem in der Seitenwand 40, respektive 41 fest angeordneten Lager 49, respektive 50 und eine die zweite Wickelwalze 3 aufnehmende Welle 51 in ebenfalls in der Seitenwand 40, respektive 41 fest angeordneten Lagern (nicht gezeigt) drehbar aufgenommen.Ultimately, the shaft 23 is rotatably received in a bearing 49 or 50 fixedly arranged in the side wall 40 or 41 and a shaft 51 receiving the second winding roller 3 is also rotatably received in bearings (not shown) which are also fixedly arranged in the side wall 40 or 41.

Der Antrieb der Welle 51 und der Übertrieb von dieser Welle zur Welle 23 ist nicht dargestellt und nicht Gegenstand der Erfindung, geschieht jedoch in an sich bekannter Weise mit Kettenübertrieben.The drive of the shaft 51 and the overdrive from this shaft to the shaft 23 is not shown and is not the subject of the invention, but is done in a manner known per se with chain exaggerations.

Mit den Figuren 2, 5, 8 und 8A ist eine Variante der mit den Figuren 1,4,7 und 7A gezeigten Vorrichtung dargestellt.FIGS. 2, 5, 8 and 8A show a variant of the device shown in FIGS. 1, 4, 7 and 7A.

Darin sind alle gleichen und/oder gleich funktionierenden Elemente mit den gleichen Bezugszeichen versehen und deshalb nicht wieder beschrieben.All the same and / or functionally identical elements are provided with the same reference symbols and are therefore not described again.

Diese Variante bezieht sich auf einen Ersatz der Kraftübertragungshebel 24 und 25 durch Kraftübertragungshebel 124, respektive 125 und einen Ersatz der Rollen 28, respektive 29 durch Rollen 128, respektive 129.This variant relates to a replacement of the power transmission levers 24 and 25 by power transmission levers 124 or 125 and a replacement of the rollers 28 or 29 by rollers 128 or 129.

Der Kraftübertragungshebel 124, respektive 125 is fest mit der Büchse 21, respektive 22 verbunden.The power transmission lever 124 or 125 is firmly connected to the bushing 21 or 22.

Die Rolle 128, respektive 129 ist drehbar in einem Lagerblock 130, respektive 131 gelagert, welcher seinerseits an einer der Welle 23 zugewandten Seite 52, respektive 53 des Tragarmes 26 respektive 27 befestigt ist.The roller 128 or 129 is rotatably mounted in a bearing block 130 or 131, which in turn is fastened to a side 52 or 53 of the support arm 26 or 27 facing the shaft 23.

Dabei ist die Lage dieses Lagerbockes 130, respektive 131 an der Seite 52, respektive 53, in bezug auf einen Abstand D je nach Konstruktion der Maschine von Fall zu Fall zu bestimmten, wobei der Abstand D, der Abstand zwischen einer die Längsachsen (nicht dargestellt) der Wellen 23 und 51 beinhaltenden Ebene 54 und einer die Längsachse (nicht dargestellt) der Rolle 128, respektive 129 beinhaltenden und zur Ebene 54 parallel liegenden Ebene 55 ist. Dieser Abstand D muß in Relation zum Verlauf einer in den Figuren 2 und 8 gezeigten Krümmung einer auf der Rolle 128, respektive 129 aufliegenden, je zum Kraftübertragungshebel 124, respektive 125 gehörende Steuerfläche 148 gewählt werden. Dabei soll der Verlauf der Krümmung, wie bereits früher definiert, die Veränderung des Krümmungsradius der Steuerfläche 148, von der mit dem Biegeradius r10 gekennzeichneten Ausgangslage bis zu der mit dem Biegeradius r20 gekennzeichneten Endlage der Rolle 128, respektive 129 verstanden werden.The position of this bearing block 130 or 131 on the side 52 or 53, with respect to a distance D, is to be determined from case to case depending on the design of the machine, the distance D, the distance between the longitudinal axes (not shown) ) of the shafts 23 and 51 containing plane 54 and a plane 55 containing the longitudinal axis (not shown) of the roller 128 or 129 and lying parallel to the plane 54. This distance D must be selected in relation to the course of a curvature shown in FIGS. 2 and 8 of a control surface 148 lying on the roller 128 or 129 and belonging to the power transmission lever 124 or 125. The course of the curvature, as already defined earlier, is to be understood as the change in the radius of curvature of the control surface 148, from the starting position marked with the bending radius r10 to the end position of the roller 128 or 129 marked with the bending radius r20.

Diese Ausgangslage ist wie in Figur 2 gezeigt, diejenige Lage, in welcher der genannte Abstand D eingehalten ist.As shown in FIG. 2, this starting position is the position in which the stated distance D is maintained.

Im Betrieb, d. h. beim Aufbau des Wickels 5 funktioniert der Wickelapparat in der früher beschriebenen Weise, wobei die Kraftübertragungshebel 124 und 125 die Schwenkarme 14 und 15 und damit das Glätteblech 8 aus der Ausgangsposition in die Endposition verschieben.In operation, d. H. when the winding 5 is built up, the winding apparatus functions in the manner previously described, the force transmission levers 124 and 125 moving the swivel arms 14 and 15 and thus the smoothing plate 8 from the starting position into the end position.

Die Figuren 3, 6, 9 und 9A zeigen eine weitere Variante der mit den Figuren 1, 4, und 7A beschriebenen Vorrichtung. Dementsprechend haben auch in dieser Variante gleiche und/oder gleich funktionierende Elemente dieselben Bezugszeichen und werden nicht wieder beschrieben.Figures 3, 6, 9 and 9A show a further variant of the device described with Figures 1, 4, and 7A. Accordingly, the same and / or the same functioning elements have the same reference numerals in this variant and are not described again.

In dieser Variante wird der Schwenkarm 14, respektive 15 mittels eines Teleskoparmes 224, respektive 225 aus der früher erwähnten Ausgangsposition in die Endposition geschwenkt.In this variant, the swivel arm 14 or 15 is swiveled from the previously mentioned starting position into the end position by means of a telescopic arm 224 or 225.

Der Teleskoparm 224, respektive 225 ist deshalb einerseits mit der Büchse 21, respektive 22 fest und andererseits mit einem auf der Seite 52, respektive 53 des Tragarmes 26, respektive 27 angeordneten Supports 226, respektive 227 mittels eines Schwenkbolzens 228, respektive 229 schwenkbar verbunden.The telescopic arm 224 or 225 is therefore fixed on the one hand with the bushing 21 or 22 and on the other hand with one on the side 52 or 53 of the support arm 26 or 27 arranged supports 226 or 227 pivotally connected by means of a pivot pin 228 or 229.

Der Support 226, respektive 227 seinerseits ist mittels Schrauben 230 auf dem Tragarm 26, respektive 27 befestigt.The support 226 or 227 in turn is attached to the support arm 26 or 27 by means of screws 230.

Um die Lage dieses Supports innerhalb eines gegebenen Bereiches verändern zu können, sind, wie in Figur 9 und 9A angedeutet die Schrauben 230 in vorgesehenen Schlitzen 231 geführt, sodass bei gelösten Schrauben 230 der Support 226, respektive 227 in der, in der Figur 9 angedeuteten Richtung M oder N verschiebbar ist.In order to be able to change the position of this support within a given area, the screws 230 are guided in provided slots 231, as indicated in FIGS. 9 and 9A, so that when screws 230 are loosened, the support 226 or 227 in the one indicated in FIG. 9 Can be moved in the M or N direction.

Die Folge dieser Veränderbarkeit der Lage des Supports liegt darin, dass dadurch der Schwenkwinkel β, um welchen die Teleskoparme geschwenkt werden, verändert werden kann. Beispielsweise wird beim Verschieben des Supports in Richtung M der Schwenkwinkel β verkleinert während in der Umkehrung beim Verschieben des Supports in Richtung N der Schwenkwinkel β vergrössert wird.The consequence of this changeability of the position of the support is that the pivoting angle β by which the telescopic arms are pivoted can thereby be changed. For example, when the support is moved in the M direction, the swivel angle β is reduced, while, conversely, when the support is moved in the N direction, the swivel angle β is increased.

Die Veränderung des Schwenkwinkels β dient der Anpassung des Abstandes zwischen dem vorderen Ende 12 des Glättebleches 8 und dem im Betrieb grösser werdenden Wickel 5, d. h., dass bei im Betrieb zunehmendem Abstand zwischen dem vorderen Ende 12 und dem Wickel 5, der Support 226, respektive 227 soweit in Richtung M verschoben wird, bis der vorgenannte Abstand im wesentlichen konstant bleibt.The change in the pivoting angle β serves to adapt the distance between the front end 12 of the smoothing plate 8 and the winding 5, which becomes larger during operation, d. that is, when the distance between the front end 12 and the winding 5 increases during operation, the support 226 or 227 is displaced in the direction M until the aforementioned distance remains essentially constant.

Letztlich zeigen die Figuren 17 und 18 eine Variante in welcher die bisher gezeigten und beschriebenen Elemente gleicher Art und/oder gleicher Funktion mit den selben Bezugszeichen versehen sind.Finally, FIGS. 17 and 18 show a variant in which the elements of the same type and / or the same function shown and described so far are provided with the same reference numerals.

In dieser Variante ist das Glätteblech 8 mittels einer Achse 302 schwenkbar an einer Pendelplatte 300 befestigt, die ihrerseits ebenfalls schwenkbar an zwei Trägern 301 befestigt ist. Die Träger 301 sind dabei an einer zum Wickelapparat 1 gehörenden und mit den Seitenwänden 40 und 41 verbundenen Decke 56 stationär angeordnet.In this variant, the smoothing plate 8 is pivotally attached to a pendulum plate 300 by means of an axis 302, which in turn is also pivotally attached to two brackets 301. The carriers 301 are arranged stationary on a blanket 56 belonging to the winding apparatus 1 and connected to the side walls 40 and 41.

Um die Anpresskraft des Glättebleches 8 auf die Wattebahn 7 zu erzeugen ist eine Feder 303 (Figur 18) derart um die Achse 302 gewunden, dass sie mit ihren zwei Enden 304 auf eine dem Wickel 5 zugewandte Seite 305 der Pendelplatte 300 und mit einer in der Mitte der Feder 303 vorgesehenen Schlaufe 306 auf die dem Wickel 5 zugewandte Seite des Glättebleches 8 drückt.In order to generate the pressing force of the smoothing plate 8 on the cotton web 7, a spring 303 (FIG. 18) is wound around the axis 302 in such a way that its two ends 304 are on a side 305 of the pendulum plate 300 facing the winding 5 and with one in the The loop 306 provided in the middle of the spring 303 presses on the side of the smoothing sheet 8 facing the winding 5.

Auf der, der Seite 305 gegenüber liegenden Seite 307 ist die Pendelplatte 300 mittels eines Bolzens 308 schwenkbar mit der Kolbenstange 309 eines einfachwirkenden doppelstufigen Pneumatikzylinders 310 verbunden. Dieser Pneumatikzylinder 310 ist seinerseits mittels eines Bolzens 311 schwenkbar mit einem, an der Decke 56 stationär befestigten Träger 312 verbunden.On the side 307 opposite the side 305, the pendulum plate 300 is pivotally connected to the piston rod 309 of a single-acting, double-stage pneumatic cylinder 310 by means of a bolt 308. This pneumatic cylinder 310 is in turn pivotally connected by means of a bolt 311 to a support 312 fixed to the ceiling 56.

Der Pneumatikzylinder 310 umfasst ein Zylinderge häuse 313, ein darin verschiebbarer hohler Zylinderkolben 314 und ein, in diesem verschiebbaren Kolben 315, zu welchem die Kolbenstange 309 gehört.The pneumatic cylinder 310 comprises a cylinder housing 313, a hollow cylinder piston 314 slidable therein and a piston 315 slidable therein, to which the piston rod 309 belongs.

Eine zwischen der kolbenstangenseitigen Stirnseite des Zylindergehäuses 313 und der kolbenstangenseitigen Stirnseite des Zylinderkolbens 314 eingespannte erste Druckfeder 316, verursacht im drucklosen Zustand das Zurückschieben des Zylinderkolbens 314 in seine Ausgangslage (in Figur 17 mit strichpunktierter Linie angedeutet), während das Verschieben des Kolbens 315 in seine Ausgangslage durch eine zwischen diesen Kolben und der kolbenstangenseitigen Stirnseite des Zylinderkolbens 314 eingespannte zweite Druckfeder 317 im drucklosen Zustand verursacht wird.A first compression spring 316 clamped between the piston rod side end of the cylinder housing 313 and the piston rod side end of the cylinder piston 314 causes the cylinder piston 314 to be pushed back into its initial position (indicated by a dash-dotted line in FIG. 17), while the piston 315 is pushed into it Starting position is caused by a second compression spring 317 clamped between these pistons and the end face of the cylinder piston 314 on the piston rod side in the depressurized state.

Für das der Kraft der ersten Druckfeder 316 entgegengerichtete Vorwärtsschieben des Zylinderkolbens 314 wird das Zylindergehäuse 313 mittels einer ersten Drückluftleitung 318 und für das Vorwärtsschieben des Kolbens 315, der Zylinderkolben 314 mittels einer Druckluftleitung 319 mit Druckluft beschickt.The cylinder housing 313 is supplied with compressed air by means of a first compressed air line 318 for the forward pushing of the cylinder piston 314 against the force of the first compression spring 316, and compressed air is used to push the piston 315 forward, the cylinder piston 314 by means of a compressed air line 319.

Dieses Verschieben geschieht für den Zylinderkolben 314 aus der in der Figur 17 mit strichpunktierter Linie gezeigten Ausgangslage in die mit ausgezogener Linie gezeigte Endlage und für den Kolben 315 aus der in Figur 17 gezeigten Ausgangslage in eine nicht gezeigte Endlage, in welcher die Pendelplatte 300 die in Figuren 17 und 19 mit strichpunktierten Linien gezeigte Lage einnimmt.This displacement takes place for the cylinder piston 314 from the starting position shown in broken lines in FIG. 17 to the end position shown with the solid line and for the piston 315 from the starting position shown in FIG. 17 into an end position (not shown), in which the pendulum plate 300 is in the position shown in FIG Figures 17 and 19 occupies the position shown with dash-dotted lines.

Durch das Verschieben des Zylinderkolbens 314 aus der Ausgangs- in die Endlage, wird die Pendelplatte 300 aus ihrer in der Figur 17 und 19 mit gestrichelten Linien gezeigten Endposition in ihre mit ausgezogenen Linien gezeigten Ausgangsposition geschwenkt.By moving the cylinder piston 314 from the starting position to the end position, the pendulum plate 300 is pivoted from its end position shown in dashed lines in FIGS. 17 and 19 into its starting position shown in solid lines.

Durch das Verschieben des Kolbens 315 aus seiner Ausgangslage in seine Endlage wird die Pendelplatte weiter in die sogenannte Ausstossposition (in Figur 17 und 19 mit strichpunktierten Linien dargestellt) geschwenkt, in welcher ein fertig erstellter Wickel 5 auf eine Aufnahmeplatte 57 gestossen wird.By moving the piston 315 from its starting position into its end position, the pendulum plate is pivoted further into the so-called ejection position (shown in dash-dotted lines in FIGS. 17 and 19), in which a finished winding 5 is pushed onto a receiving plate 57.

Beim Verschieben des Zylinderkolbens 314 und/oder des Kolbens 315 wird der Zylinder 313 und/oder der Zylinderkolben 314 über die Entlüftungsöffungen 320, respektive 321 entlüftet.When the cylinder piston 314 and / or the piston 315 are displaced, the cylinder 313 and / or the cylinder piston 314 is vented via the ventilation openings 320 and 321, respectively.

Eine Verlängerung oder eine Verkürzung des Schwenkweges der Pendelplatte 300 kann durch eine Veränderung der Lage des den Bolzen 308 beinhaltenden Scharnieres 342 entlang der Schwenkplatte 300 erreicht werden.An extension or a shortening of the swivel path of the pendulum plate 300 can be achieved by changing the position of the hinge 342 containing the bolt 308 along the swivel plate 300.

Beim Start des Wickelapparates sind die Tragarme 26 und 27 in der in Figur 17 gezeigten unteren Lage, in welcher eine auf die Wickelwalzen 2, 3 gelegte leere Wickelhülse von den Pneumatikzylindern 30, 31 erfasst werden kann.At the start of the winding apparatus, the support arms 26 and 27 are in the lower position shown in FIG. 17, in which an empty winding tube placed on the winding rollers 2, 3 can be gripped by the pneumatic cylinders 30, 31.

In dieser Lage betätigt ein am Tragarm 27 vorgesehener Schaltnocken 322 ein durch eine Tastrolle gesteuertes 3/2 Wege-Ventil 323, mit Sperr-Null-Stellung, sodass eine Steuerleitung 324 mit Druckluft beschickt und damit ein einseitig druckgesteuertes 3/2 Wege-Ventil 325 mit Sperr-Null-Stellung betätigt wird.In this position, a switching cam 322 provided on the support arm 27 actuates a 3/2-way valve 323 controlled by a feeler roller, with the blocking zero position, so that a control line 324 feeds compressed air and thus a one-sided pressure-controlled 3/2 way valve 325 is actuated with the zero position.

Durch die Betätigung des Ventiles 325 wird der Weg frei zur Betätigung eines mittels einer Steuerleitung 339 damit verbundenen doppelseitig druckgesteuerten 3/2 Wegeschieberventiles 326 in Sperr-Stellung, und zwar derart, dass durch kurzes Betätigen eines mittels Druckknopf gesteuerten 3/2 Wege-Ventils 327 mit Sperr-Null-Stellung, das Schieberventil 326 auf den Durchlass der Druckluft umgeschaltet und damit die Druckleitung 318 mit Druckbeauf schlagt wird. Dadurch wird die Pendelplatte 300 in die Ausgangsstellung gebracht.The actuation of the valve 325 clears the way for actuating a double-sided pressure-controlled 3/2 directional spool valve 326 connected to it by means of a control line 339, in such a way that by briefly actuating a 3/2 way valve 327 controlled by means of a push button With the zero lock position, the slide valve 326 is switched to the passage of the compressed air and thus the pressure line 318 is pressurized. As a result, the pendulum plate 300 is brought into the starting position.

Beim Start des Wickelvorganges wird ein elektromagnetisch gesteuertes 3/2 Wege-Ventil 328 mit Sperr-Null-Stellung, kurz betätigt, wodurch eine Steuerleitung 336 kurz mit Druck beaufschlagt und dadurch das Schieberventil 326 wieder in die, in Figur 19 gezeigte Ausgangsstellung zurück versetzt wird. Dadurch wird die Druckleitung 318 über das Schieberventil 326 mit einem mittels Tastrolle gesteuerten Druckregelventil 329, mit Abflussöffnung, verbunden.At the start of the winding process, an electromagnetically controlled 3/2-way valve 328 with a blocking zero position is briefly actuated, as a result of which pressure is briefly applied to a control line 336 and the slide valve 326 is thereby returned to the starting position shown in FIG. 19 . As a result, the pressure line 318 is connected via the slide valve 326 to a pressure control valve 329 controlled by means of a sensing roller and having an outlet opening.

Die Tastrolle des Druckregelventils 329 liegt auf einer Steuerfläche 330 eines mit dem Gleitelement 36 verbundenen Steuerlineales 331 auf.The feeler roller of the pressure control valve 329 lies on a control surface 330 of a control ruler 331 connected to the sliding element 36.

Durch die Bewegung der Tragarme 26, 27, bei grösserwerdendem Wickel 5, verschiebt sich das Steuerlineal 331 zwangsläufig in der in Figur 19 mit dem Pfeil D gezeigten Richtung, wodurch die Stellung der Tastrolle derart verändert und damit das Druckregelventil derart gesteuert wird, dass der Druck in der Druckleitung 318 zunehmend reduziert wird.As a result of the movement of the support arms 26, 27 when the winding 5 becomes larger, the control ruler 331 inevitably shifts in the direction shown by the arrow D in FIG. 19, as a result of which the position of the feeler roller is changed and the pressure control valve is thus controlled in such a way that the pressure is increasingly reduced in the pressure line 318.

Die Steuerfläche 330 ist nun derart geformt, dass die Pendelplatte 300 bei grösserwerdendem Wickel 5, derart kontinuierlich aus der Ausgangslage in die in Figur 17 und 19 mit gestrichelten Linien dargestellte Endlage zurückweicht, dass der Abstand des vorderen Endes 12 des Glättebleches 8 zum Wickel 5 im wesentlichen gleich bleibt.The control surface 330 is now shaped in such a way that the pendulum plate 300 continuously recedes from the starting position into the end position shown in dashed lines in FIGS. 17 and 19 when the winding 5 grows in such a way that the distance between the front end 12 of the smoothing plate 8 and the winding 5 im remains essentially the same.

Bei Erreichen des Enddurchmessers des Wickels 5 betätigt der Schaltnocken 322 kurz ein mittels Tastrolle gesteuertes 3/2 Wege-Ventil 332 mit Sperr-Null-Stellung, welches dadurch das Schieberventil 326 über eine Steuerleitung 337 derart steuert, dass es wieder in die Durchlaß-stellung verschoben wird, wodurch die Druckleitung 318 mit Druck beaufschlagt und der Zylinderkolben 314 gegen die Federkraft in seine Endlage verschoben wird. Gleichzeitig, d. h. mit demselben Druckimpuls wird ein weiteres, mit der Steuerleitung 337 verbundenes, 3/2 Wege-Schieberventil 333, in Sperr-Stellung, derart betätigt; dass es aus der Sperr- Stellung in die Durchlaß-stellung verschoben und damit die Druckleitung 319 mit Druck beaufschlagt wird. Dadurch wird der Kolben 315 unmittelbar nach Erreichen der Endlage des Zylinderkolbens 314 aus seiner in Figur 17 gezeigten Ausgangslage gegen den Druck der Feder 317 in seine Endlage (nicht gezeigt) verschoben. Als Folge davon wird die Pendelplatte 300 in die in den Figuren 17 und 19 mit strichpunktierten Linien dargestellte Ausstossposition gebracht, sodass der fertige Wickel 5 auf die Aufnahmeplatte 57 gestossen wird und aus dem Wickelapparat 1 entfernt werden kann. In dieser Ausstossposition betätigt die Pendelplatte 300 ein durch eine Tastrolle betätigbares 3/2 Wege-Ventil 334, mit Sperr-Null- Stellung, welches über eine Steuerleitung 338 mit dem Schieberventil 333 verbunden ist und dadurch dieses in die Sperr-Stellung zurückversetzt, sodass die Druckleitung 319 wieder entlüftet und der Kolben 315 wieder mittels Kraft der Feder 317 ebenfalls wieder in seine Ausgangsstellung zurück versetzt wird. Die Pendelplatte 300 hat dadurch wieder ihre mit ausgezogenen Linien dargestellte Ausgangsstellung erreicht.When the final diameter of the winding 5 is reached, the switching cam 322 briefly actuates a 3/2-way valve 332 controlled by a feeler roller with a zero blocking position, which thereby controls the slide valve 326 via a control line 337 in such a way that it returns to the open position is displaced, whereby the pressure line 318 is pressurized and the cylinder piston 314 is displaced into its end position against the spring force. At the same time, d. H. With the same pressure pulse, a further 3/2 way slide valve 333, connected to the control line 337, is actuated in the blocking position; that it is shifted from the blocking position into the open position and thus the pressure line 319 is pressurized. As a result, the piston 315 is displaced from its initial position shown in FIG. 17 against the pressure of the spring 317 into its end position (not shown) immediately after the end position of the cylinder piston 314 has been reached. As a result, the pendulum plate 300 is brought into the ejection position shown with dash-dotted lines in FIGS. 17 and 19, so that the finished roll 5 is pushed onto the receiving plate 57 and can be removed from the winding apparatus 1. In this ejection position, the pendulum plate 300 actuates a 3/2-way valve 334, which can be actuated by a feeler roller, and has a blocking zero position, which is connected via a control line 338 to the slide valve 333, thereby moving it back into the blocking position, so that the Pressure line 319 is vented again and the piston 315 is also returned to its starting position by means of the spring 317. As a result, the pendulum plate 300 has again reached its starting position shown with solid lines.

Beim Absenken der Tragarme 26, 27 wird das Ventil 332 in Folge des Leerrücklaufes an der Tastrolle nicht betätigt, sodass das Schieberventil 333 in Sperr-Stellung bleibt.When the support arms 26, 27 are lowered, the valve 332 is not actuated due to the empty return on the sensing roller, so that the slide valve 333 remains in the blocking position.

Haben die Tragarme die Ausgangsstellung wieder erreicht, so wird das Ventil 323 und damit das Ventil 325 wieder betätigt. Ohne das für diese Situation jedoch nicht notwendige Betätigen des Ventiles 327 bleibt diese Betätigung der Ventile 323 und 325 für das Schieberventil 326 wirkungslos. Das Schieberventil 326 wird dann auf die in Figur 19 gezeigte Nullstellung gebracht, wenn, nachdem eine neue Wickelhülse 4 eingespannt wurde, beim Start des Wickelvorganges das Ventil 328 betätigt, d. h. mittels elektrischem Steuerimpuls angesteuert und die Steuerleitung 336 kurz unter Druck gesetzt wird.When the support arms have reached the starting position again, the valve 323 and thus the valve 325 are actuated again. Without actuating valve 327, which is not necessary for this situation, this actuation of valves 323 and 325 remains ineffective for slide valve 326. The slide valve 326 is then brought to the zero position shown in FIG. 19 if, after a new winding tube 4 has been clamped in, the valve 328 is actuated at the start of the winding process, i. H. controlled by means of an electrical control pulse and the control line 336 is briefly pressurized.

Der beschriebene Vorgang des Wickelaufbaues wird nun wiederholt. Die für den genannten Vorgang benötigte Druckluft wird an den Druckluftanschlußstellen 335 eingespeist. Um zu vermeiden, dass beim früher erwähnten Betätigen des Ventiles 327 gleichzeitig die Steuerleitung 337 mit Druck beaufschlagt wird, ist in dieser Steuerleitung, unmittelbar vor dem Anschluss an die Steuerleitung 339, ein Rückschlagventil 340 eingebaut.The process of winding construction described is now repeated. The compressed air required for the above-mentioned process is fed in at the compressed air connection points 335. In order to prevent the control line 337 from being simultaneously pressurized when the valve 327 is actuated, a check valve 340 is installed in this control line immediately before the connection to the control line 339.

Letztlich ist in der Steuerleitung 339, zwischen dem Anschluss der Steuerleitung 337 und dem Ventil 325, ein verstellbares Drosselrückschlagventil 341 mit gegen das Ventil 325 gerichteten Sperrung vorgesehen. Die Drosselstelle ist dabei derart eingestellt, dass, einerseits ein von der Steuerleitung kommender Druckimpuls mit genügendem Druck das Ventil 326 betätigt, andererseits eine Entlüftung der Steuerleitung 339 über das Ventil 325 möglich ist. Das dazugehörige Rückschlagventil erlaubt einem vom Ventil 327 abgegebenen Druckimpuls, die Drosselstelle zu umgehen.Finally, in the control line 339, between the connection of the control line 337 and the valve 325, an adjustable throttle check valve 341 is provided with a blocking directed against the valve 325. The throttle point is set in such a way that, on the one hand, a pressure pulse coming from the control line actuates the valve 326 with sufficient pressure, and on the other hand a venting of the control line 339 via the valve 325 is possible. The associated check valve allows a pressure pulse emitted by valve 327 to bypass the throttle point.

Mit Figur 12 wird gezeigt, dass das vordere Ende, auch Glättekante genannt, des Glättebleches als gezahntes vorderes Ende 12.1 ausgeführt werden kann. Der Vorteil einer solchen Zahnung ist folgendermassen an Hand der Figuren 15 und 16 erklärbar:FIG. 12 shows that the front end, also called the smoothing edge, of the smoothing plate can be designed as a toothed front end 12.1. The advantage of one Such toothing can be explained as follows using FIGS. 15 and 16:

Die in Förderrichtung F verschobene Wattebahn 7 setzt sich aus einer Schicht Fasern 58 zusammen, welche im wesentlichen in eine in der Förderrichtung F gerichtete Orientierung haben, d. h. welche etwas übertrieben gesagt im wesentlichen parallel neben- und übereinander liegen und dabei die Wattebahn 7 bilden. Durch diese Parallellage der Fasern 58 besteht eine gewisse Möglichkeit, dass sich beim Bilden des Wickels 5 Fasern benachbarten Oberflächen in eine nebeneinander Lage geraten und sich dabei in Folge des Wickeldruckes derart ineinander verkeilen, dass eine gewisse Gefahr des gegenseitigen Aneinanderhaftens der Oberflächen besteht. Dieses Aneinanderhaften kann beim Wiederabwickeln des Wickels 5 insofern nachteilig sein, als sich der Wickel 5 dadurch entweder schlecht entrollen lässt oder dass sich beim Abwickeln des Wickels 5, d. h. beim Wiederlösen der aufeinander liegenden Wattebahn ganze Faserverbände aus der einen Oberfläche heraus gelöst werden und an der gegenüberliegenden Oberfläche als Verdickung hängen bleiben.The cotton web 7 displaced in the conveying direction F is composed of a layer of fibers 58 which are essentially oriented in the conveying direction F, i. H. which, somewhat exaggerated, are essentially parallel to one another and one above the other and thereby form the cotton web 7. Due to this parallel position of the fibers 58, there is a certain possibility that, when the roll 5 is formed, adjacent surfaces become in a side-by-side position and wedge into one another as a result of the winding pressure in such a way that there is a certain risk of the surfaces adhering to one another. This sticking together can be disadvantageous when rewinding the winding 5 in that the winding 5 is either difficult to unroll or that when the winding 5 is unwound, i. H. When the cotton web lying on top of one another is detached, entire fiber associations are detached from one surface and remain as a thickening on the opposite surface.

Um diesen Nachteil mindestens teilweise abzubauen, wird das vordere Ende des Glättebleches mit Zähnen 12.1 versehen, welche die im wesentlichen parallel liegenden Fasern 58 mindestens an der Oberfläche und mindestens teilweise derart umlenken, dass die Fasern an der Oberfläche bis zu einem gewissen Grad eine Wirrlage erhalten. Diese Wirrlage hilft nun dem Aneinanderhaften von zwei Wattebahnen entgegen zu wirken.In order to at least partially alleviate this disadvantage, the front end of the smoothing plate is provided with teeth 12.1, which deflect the fibers 58 lying essentially parallel, at least on the surface and at least partially in such a way that the fibers on the surface get a tangled position to a certain degree . This confusion now helps to counteract the sticking together of two cotton wool sheets.

Um den Glätteeffekt des geradlinigen vorderen Endes 12 mit dem vorteilhaften Wirrlageeffekt der Zähne 12.1 zu kombinieren, ist wie mit Figur 13 und 14 gezeigt, vorgeschlagen die mit Zähnen 12.1 versehene federnde Zunge 9 mit einer daran befestigten Zunge 9.1 zu kombinieren deren vorderes Ende 12 geradlinig und den Zähnen 12.1, in Förderrichtung F gesehen, nachgeschaltet ist. Diese Kombination wird als Glätteblech 8.1 bezeichnet und ist im Übrigen in gleicher Weise befestigt wie das Glätteblech 8.In order to combine the smooth effect of the rectilinear front end 12 with the advantageous tangle effect of the teeth 12.1, as shown with FIGS. 13 and 14, it is proposed to combine the resilient tongue 9 provided with teeth 12.1 with a tongue 9.1 attached to it, the front end 12 of which is rectilinear and the teeth 12.1, seen in the conveying direction F, is connected downstream. This combination is referred to as the smoothing plate 8.1 and is otherwise attached in the same way as the smoothing plate 8.

Ferner zeigt die Figur 20 eine vereinfachte Variante der Vorrichtung von Figur 17. Dementsprechend sind die gleichen Elemente mit denselben Bezugszeichen versehen.FIG. 20 also shows a simplified variant of the device from FIG. 17. Accordingly, the same elements are provided with the same reference symbols.

In dieser Variante wandert das Glätteblech 8 nicht mit grösserwerdenden Wickel 5, sondern bleibt während der Bildung des Wickels 5 in der in Figur 20 mit ausgezogenen Linien gezeichneten Endlage.In this variant, the smoothing sheet 8 does not move with the winding 5 becoming larger, but remains in the end position drawn in solid lines in FIG. 20 during the formation of the winding 5.

Nach Fertigstellung des Wickels 5 wird die Pendelplatte 300 in die mit strichpunktierten Linien dargestellten Ausstossposition gebracht, um dadurch den fertigen Wickel auf die Aufnahmeplatte 57 zu schieben.After the winding 5 has been completed, the pendulum plate 300 is brought into the ejection position shown with dash-dotted lines, in order thereby to push the finished winding onto the receiving plate 57.

Im Betrieb steuert die früher erwähnte, in der Schweizer Patentanmeldung Nr. 5561/83-3 aufgeführte Steuerung den Wickelaufbau in der bereits beschriebenen Art.In operation, the control mentioned earlier in Swiss patent application No. 5561 / 83-3 controls the winding structure in the manner already described.

Bei Fertigstellung des Wickels 5, d. h. in der oberen Endlage der Tragarme 26 und 27, betätigt der Schaltnocken 322 das Ventil 332, wodurch das Ventil 333 über eine Steuerleitung 343 derart betätigt wird, dass eine das Ventil 333, mit einem einfach wirkenden Pneumatikzylinder 346 verbindende Druckleitung 345 mit Druckluft beschickt wird. Dadurch wird die Kolbenstange 348, bei Entlüftung des kolbenstangenseitigen Zylinderraumes über die Leitung 347, gegen die Kraft der Druckfeder des Zylinders 346 so lange verschoben, bis die Pendelplatte die Ausstossposition erreicht hat.When the winding 5, d. H. In the upper end position of the support arms 26 and 27, the switching cam 322 actuates the valve 332, whereby the valve 333 is actuated via a control line 343 such that a pressure line 345 connecting the valve 333 with a single-acting pneumatic cylinder 346 is supplied with compressed air. As a result, the piston rod 348 is displaced against the force of the compression spring of the cylinder 346 until the pendulum plate has reached the ejection position when the cylinder chamber on the piston rod side is vented via the line 347.

In dieser Position wird das Ventil 334 durch die Pendelplatte 300 derart betätigt, dass eine das Ventil 334 mit dem Ventil 333 verbindende Steuerleitung mit Druck beaufschlagt wird. Dadurch wird das Ventil wieder zurück in die Position versetzt, in welcher die Druckleitung 345 entlüftet und die Kolbenstange 348 zurück in die Ausgangslage versetzt wird. Der Wickelaufbau kann damit wieder von vorne beginnen.In this position, the valve 334 is actuated by the pendulum plate 300 in such a way that a control line connecting the valve 334 to the valve 333 is pressurized. As a result, the valve is returned to the position in which the pressure line 345 is vented and the piston rod 348 is returned to the starting position. The winding structure can thus start again from the beginning.

Letztlich sei noch erwähnt, dass das Glätteblech 8 oder 8.1 auch in einer stationären Art vorgesehen werden kann, in dem beispielsweise die Pendelplatte 300 im Betrieb in ihrer, in Figur 17 mit gestrichelten Linien dargestellten Endlage bleibt.Finally, it should also be mentioned that the smoothing plate 8 or 8.1 can also be provided in a stationary manner, in which, for example, the pendulum plate 300 remains in operation in its end position shown in dashed lines in FIG. 17.
