  • JP H03 177253 A discloses a winder in which an empty winding shaft is moved along a horizontally extending running surface in the winding-on position between two rollers.
  • the object of the invention is therefore to improve the safety of a fleece winder when conveying the winding shaft from the waiting position to the starting position.

  • the guide section has a running surface which essentially points away from a floor on which the fleece winder is set up and is designed to take up the weight of the winding shaft.
  • the transport section and guide section are also designed to move the winding shaft from the holding section on the running surface in the direction of a winding-on position in which the web winder is set up to wind the winding shaft with a web located on a contact roller of the web winder.

  • the winding shaft is guided near the running surface, where near means a range of a few millimeters or even below a millimeter.
  • the transport section has to take up the weight of the winding shaft, but a malfunction does not lead to the winding shaft that may come loose in an uncontrolled manner or cause damage to the fleece winder.
  • the low height of fall means that there is hardly any risk of damage to the running surface.

Description

Die Erfindung betrifft eine Vorrichtung zum Transportieren einer Wickelwelle in einem Vlieswickler von einer Warte- in eine Anwickelposition und von dieser in eine Wickelposition des Vlieswicklers sowie einen damit ausgestatteten Vlieswickler.The invention relates to a device for transporting a winding shaft in a fleece winder from a waiting position to a start-up position and from this to a winding position of the fleece winder, as well as a fleece winder equipped therewith.

Vlieswickler an sich sind bekannt. Sie dienen dazu, ein beispielsweise aus einer Karde herauskommendes Vlies auf eine Wickelwelle aufzuwickeln. Dazu werden leere Wickelwellen in einem Magazin des Vlieswicklers eingelegt und nach und nach zunächst in eine Warteposition gebracht. Die Warteposition dient dazu, zum einen die Wickelwelle von den anderen Wickelwellen zu separieren und sie zum anderen vor dem Beginn des eigentlichen Wickelvorgangs in Rotation zu versetzen. Um eine Wickelwelle anzuwickeln, ist vorgesehen, die Wickelwelle von der Warteposition in eine Anwickelposition zu befördern, in der die zu bewickelnde Wickwelle mit einer Kontaktwalze, auf der das Vlies entlangläuft, im Bereich des Vlieses in Reibungskontakt gelangt. Bei diesem Befördern wird die Wickelwelle beidseitig mittels Hebeln verriegelt und quasi schwebend in die Anwickelposition gebracht. Tritt nun eine Störung auf, sodass die Beförderung unterbrochen wird, kann es passieren, dass die Wickelwelle in der Luft hängen bleibt. Dies ist insbesondere für einen Bediener eine sehr gefährliche Situation, da sich die Wickelwelle lösen und abfallen könnte. JP H03 177253 A offenbart einen Wickler bei dem eine leere Wickelwelle entlang einer horizontal verlaufenden Lauffläche in Anwickelposition zwischen zwei Walzen bewegt wird.Fleece winder per se are known. They serve to wind a fleece coming out of a card, for example, onto a winding shaft. For this purpose, empty winding shafts are placed in a magazine of the fleece winder and gradually brought into a waiting position. The waiting position serves, on the one hand, to separate the winding shaft from the other winding shafts and, on the other hand, to set it in rotation before the actual winding process begins. In order to wind a winding shaft, it is provided to convey the winding shaft from the waiting position to a winding position in which the winding shaft to be wound comes into frictional contact with a contact roller on which the fleece runs in the area of the fleece. During this transport, the winding shaft is locked on both sides by means of levers and brought into the winding-on position, as it were, floating. If a malfunction occurs, so that the transport is interrupted, it can happen that the winding shaft gets stuck in the air. This is a very dangerous situation, in particular for an operator, since the winding shaft could loosen and fall off. JP H03 177253 A discloses a winder in which an empty winding shaft is moved along a horizontally extending running surface in the winding-on position between two rollers.

Aufgabe der Erfindung ist es daher, die Sicherheit eines Vlieswicklers beim Befördern der Wickelwelle von der Warteposition in die Anwickelposition zu verbessern.The object of the invention is therefore to improve the safety of a fleece winder when conveying the winding shaft from the waiting position to the starting position.

Diese Aufgabe wird durch den Gegenstand der Ansprüche 1 und 13 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object is achieved by the subject matter of claims 1 and 13. Advantageous further developments are given in the subclaims.

Erfindungsgemäß ist ein Vlieswickler vorgesehen, der einen Halteabschnitt, einen Transportabschnitt und einen Führungsabschnitt aufweist. Der Halteabschnitt ist gestaltet, eine Wickelwelle aufzunehmen. Der Führungsabschnitt weist eine im Wesentlichen von einem Boden, auf den der Vlieswickler aufgestellt ist, weg weisende Lauffläche auf und ist gestaltet, das Gewicht der Wickelwelle aufzunehmen. Transportabschnitt und Führungsabschnitt sind ferner gestaltet, die Wickelwelle vom Halteabschnitt auf der Lauffläche in Richtung einer Anwickelposition zu bewegen, in der der Vlieswickler eingerichtet ist, die Wickelwelle mit einem sich auf einer Kontaktwalze des Vlieswicklers befindlichen Vlies anzuwickeln. D. h. das Gewicht der Wickelwelle lagert während des gesamten Vorgangs auf dem Führungsabschnitt. Dies hat den Vorteil, dass die die Wickelwelle greifenden Elemente wesentlich weniger Greifkraft aufbringen müssen. Zudem kann die Wickelwelle im Fall einer Störung nicht abfallen, womit die Sicherheit insbesondere für einen Bediener verbessert ist.According to the invention, a fleece winder is provided which has a holding section, a transport section and a guide section. The holding section is designed to receive a winding shaft. The guide section has a running surface which essentially points away from a floor on which the fleece winder is set up and is designed to take up the weight of the winding shaft. The transport section and guide section are also designed to move the winding shaft from the holding section on the running surface in the direction of a winding-on position in which the web winder is set up to wind the winding shaft with a web located on a contact roller of the web winder. I. E. the weight of the winding shaft rests on the guide section during the entire process. This has the advantage that the elements gripping the winding shaft have to apply significantly less gripping force. In addition, the winding shaft cannot fall off in the event of a malfunction, which improves safety in particular for an operator.

Alternativ wird die Wickelwelle nahe der Lauffläche geführt, wobei nahe einen Bereich weniger Millimeter oder sogar unterhalb eines Millimeters bedeutet. Dabei muss der Transportabschnitt zwar das Gewicht der Wickelwelle aufnehmen, allerdings führt eine Störung nicht dazu, dass die sich etwaig lösende Wickelwelle unkontrolliert wegfällt oder Schäden am Vlieswickler verursachen kann. Zum einen bewirkt die geringe Fallhöhe, dass an der Lauffläche kaum Beschädigungen zu befürchten sind. Zum anderen kann die Wickelwelle aufgrund ihres wesentlich größeren Durchmesser nicht den Spalt zwischen Transportabschnitt und Lauffläche verlassen, sodass sie sich weiterhin ausschließlich im Bereich des Transportabschnitts aufhalten kann.Alternatively, the winding shaft is guided near the running surface, where near means a range of a few millimeters or even below a millimeter. The transport section has to take up the weight of the winding shaft, but a malfunction does not lead to the winding shaft that may come loose in an uncontrolled manner or cause damage to the fleece winder. On the one hand, the low height of fall means that there is hardly any risk of damage to the running surface. On the other hand, due to its significantly larger diameter, the winding shaft cannot leave the gap between the transport section and the running surface, so that it can continue to be exclusively in the area of the transport section.

Erfindungsgemäß, quer zur Bewegungsrichtung der Wickelwelle gesehen, steigt der Abstand der Lauffläche vom Halteabschnitt in Richtung Anwickelposition vorzugsweise zunächst an und fällt danach wieder ab. Damit wird der Verfahrweg der Wickelwelle quasi halbiert, entlang dem die Wickelwelle bei Störung und möglichen Lösens von der Greifeinrichtung, die die Wickelwelle ergreifen soll, wegrollen kann. Dies verringert die Endgeschwindigkeit der Wickelwelle und dient damit ebenfalls der Betriebssicherheit.According to the invention, viewed transversely to the direction of movement of the winding shaft, the distance between the running surface and the holding section preferably first increases in the direction of the winding position and then decreases again. The travel path of the winding shaft, along which the winding shaft can roll away in the event of a malfunction and possible loosening of the gripping device that is intended to grip the winding shaft, is thus virtually halved. This reduces the final speed of the winding shaft and thus also improves operational safety.

Vorzugsweise verläuft die Lauffläche dabei kontinuierlich. Somit gibt es während der Beförderung der Wickelwelle kaum Erschütterungen am Vlieswickler.The running surface preferably runs continuously. This means that there are hardly any vibrations on the web winder while the winding shaft is being transported.

Dabei ist die Lauffläche, quer zur Bewegungsrichtung der Wickelwelle gesehen, vorzugsweise kreisbogenartig oder elliptisch ausgebildet. Dies sind besonders gut geeignete Laufflächenformen, insbesondere Beschleunigung und Endgeschwindigkeit einer sich lösenden Wickelwelle in Grenzen zu halten.In this case, the running surface, seen transversely to the direction of movement of the winding shaft, is preferably designed as a circular arc or elliptical. These are particularly well-suited tread shapes, in particular to keep the acceleration and final speed of a winding shaft loosening within limits.

Bei jedem der vorgenannten Vlieswickler kann der Führungsabschnitt Bestandteil einer Gestellwand des Vlieswicklers sein. Diese übernimmt mithin eine Doppelfunktion und ermöglicht neben dem Beibehalten der Anzahl an Teilen gleichbleibende Außenabmessungen des Vlieswicklers zumindest in Breite und Länge.In each of the aforementioned web winder, the guide section can be part of a frame wall of the web winder. This therefore takes on a double function and, in addition to maintaining the number of parts, enables constant external dimensions of the web winder, at least in terms of width and length.

Zusätzlich oder alternativ kann der Vlieswickler über eine Sensorik verfügen. Diese ist eingerichtet zu detektieren, wenn sich die Wickelwelle im Halteabschnitt oder in Anwickelposition befindet. Dies ermöglicht einer Steuerung des Vlieswicklers, beispielsweise das Anlegen und/oder Trennen des Vlieses einzuleiten, wenn sich die Wickelwelle in Anwickelposition befindet.Additionally or alternatively, the fleece winder can have a sensor system. This is set up to detect when the winding shaft is in the holding section or in the starting position. This enables the web winder to be controlled, for example to initiate the application and / or separation of the web when the winding shaft is in the winding-on position.

Die Sensorik kann dabei optischer, magnetischer und/oder mechanischer Natur sein. Sie kann also auf die jeweiligen Anforderungen hin optimiert werden.The sensor system can be of an optical, magnetic and / or mechanical nature. It can therefore be optimized to the respective requirements.

Der Transportabschnitt jedes der vorgenannten Vlieswickler kann einen Verriegelungsabschnitt aufweisen. Dieser ist gestaltet, die Wickelwelle von einer der Kontaktwalze abgewandten Seite her anzugreifen. Er ist zudem an einem Bewegungsabschnitt angebracht, der eingerichtet ist, den Verriegelungsabschnitt in Richtung Kontaktwalze zu bewegen. Es kann demnach ausreichen, lediglich den Bewegungsabschnitt zu bewegen, um die Wickelwelle aus der Warteposition in die Anwickelposition zu bewegen. Dies führt zu einem sehr einfachen und kostengünstigen Aufbau.The transport section of each of the aforementioned fleece winders can have a locking section. This is designed to attack the winding shaft from a side facing away from the contact roller. It is also attached to a movement section which is set up to move the locking section in the direction of the contact roller. Accordingly, it can be sufficient to only move the movement section in order to move the winding shaft from the waiting position into the winding-on position. This leads to a very simple and inexpensive structure.

Vorzugsweise weist der Bewegungsabschnitt eine Linearführung auf, mittels der der Verriegelungsabschnitt entlang seiner Bewegung geführt wird. Die Linearführung ermöglicht den Einsatz eines pneumatischen Antriebs.The movement section preferably has a linear guide by means of which the locking section is guided along its movement. The linear guide enables the use of a pneumatic drive.

In den zwei letztgenannten Varianten umfasst der Bewegungsabschnitt vorzugsweise einen schwenkbar gelagerten Hebel. Dieser ist um eine Achse der Kontaktwalze herum rotierbar angeordnet. Der Vlieswickler ist dabei eingerichtet, die Bewegungen des Hebels und des Verriegelungsabschnitts derart abzustimmen, dass die Wickelwelle während ihrer Bewegung zur Anwickelposition sicher vom Verriegelungsabschnitt mitgenommen wird. Dies ermöglicht insbesondere bei einer anfangs ansteigenden Lauffläche, den Druck der Wickelwelle auf die Lauffläche nicht zu groß werden zu lassen, was der Betriebssicherheit zugute kommt.In the two last-mentioned variants, the movement section preferably comprises a pivotably mounted lever. This is arranged rotatably around an axis of the contact roller. The fleece winder is set up to coordinate the movements of the lever and the locking section in such a way that the winding shaft is safely carried along by the locking section during its movement to the winding position. In particular with an initially rising running surface, this makes it possible not to let the pressure of the winding shaft on the running surface become too great, which is beneficial to operational safety.

Jeder der vorgenannten Verriegelungsabschnitte kann gestaltet sein, die Wickelwelle herausfallsicher zu greifen. Dies erhöht die Sicherheit, dass sich die Wickelwelle auch bei einer Störung nicht ohne Weiteres lösen kann. Zudem kann der Führungsabschnitt mittels eines geringen Anhebens der Wickelwelle beispielsweise im Rahmen weniger Millimeter während des Beförderns der Wickelwelle zumindest teilweise von deren Gewicht entlastet werden.Each of the aforementioned locking sections can be designed to grip the winding shaft in such a way that it cannot fall out. This increases the security that the winding shaft cannot easily loosen even in the event of a malfunction. In addition, the guide section can be at least partially relieved of its weight by slightly lifting the winding shaft, for example within a few millimeters while the winding shaft is being conveyed.

Bei jedem der vorgenannten Vlieswickler können Halteabschnitt, Transportabschnitt und Führungsabschnitt jeweils doppelt vorgesehen sein, und zwar an einander gegenüberliegenden Seiten des Vlieswicklers. Dies ermöglicht, die Wickelwelle vermittels ihrer Enden befördern zu können. Die Fläche zum Aufnehmen des Vlieses untersteht mithin keiner mechanischen Belastung durch das Befördern und kann auf das Aufwickeln des Vlieses hin optimiert werden.In each of the aforementioned fleece winder, the holding section, transport section and guide section can each be provided in duplicate, specifically on opposite sides of the fleece winder. This enables the winding shaft to be conveyed by means of its ends. The area for receiving the fleece is therefore not subject to any mechanical stress from the conveyance and can be optimized for the winding up of the fleece.

Ein erfindungsgemäßes Verfahren zum Betreiben eines der vorgenannten Vlieswickler weist als erstes einen Schritt des Angreifens der sich im Halteabschnitt befindlichen Wickelwelle zumindest von einer der Kontaktwalze des Vlieswicklers abgewandten Seite her mittels eines Verriegelungsabschnitts des Vlieswicklers auf. Nachfolgend wird der Verriegelungsabschnitt im Rahmen des Verfahrens mittels des Bewegungsabschnitts des Vlieswicklers in Richtung Kontaktwalze bewegt. Ferner erfolgt ein Schritt des Detektierens des Vorliegens eines Zustands, in dem die Wickelwelle die Anwickelposition erreicht hat. Ist dieser Zustand detektiert, wird der Bewegungsabschnitt angehalten. Im Ergebnis bietet die Erfindung ein sehr einfaches Verfahren zum Befördern einer Wickelwelle von der Warteposition in die Anwickelposition.A method according to the invention for operating one of the aforementioned fleece winder first has a step of engaging the winding shaft located in the holding section at least from a side facing away from the contact roller of the fleece winder by means of a locking section of the fleece winder. Subsequently, within the scope of the method, the locking section is moved in the direction of the contact roller by means of the moving section of the fleece winder. Furthermore, there is a step of detecting the presence of a state in which the winding shaft has reached the winding-on position. If this state is detected, the movement section is stopped. As a result, the invention offers a very simple method for conveying a winding shaft from the waiting position to the winding-on position.

Figur 1 zeigt einen Vlieswickler 1 gemäß einer Ausführungsform der Erfindung. Die für die Erfindung unwesentlichen Bestandteile sind nicht weiter erläutert. Figure 1 shows a fleece winder 1 according to an embodiment of the invention. The constituents that are not essential to the invention are not explained further.

Der Vlieswickler 1 umfasst im Wesentlichen zwei Gestellwände 20, die über nicht bezeichnete Verbinder zu einem Gestell zusammengefasst sind, das alle anderen Funktionselemente des Vlieswicklers 1 aufnimmt bzw. hält.The fleece winder 1 essentially comprises two frame walls 20, which are combined to form a frame via connectors (not designated), which receives or holds all other functional elements of the fleece winder 1.

Die Gestellwände 20 weisen in einem rechten Bereich ein Magazin 2 auf, in dem sich nicht bezeichnete Wickelwellen (hier: zwei) befinden.In a right-hand area, the frame walls 20 have a magazine 2 in which there are unmarked winding shafts (here: two).

Weiterhin umfasst der Vlieswickler 1 an jeder Gestellwand 20 eine Ausnehmung, die eine Warteposition 3 für eine Wickelwelle 7 definiert. Da die Wickelwellen beidseitig von einer jeweiligen Gestellwand 20 gehalten werden, wird somit eine Warteposition 3 mittels der beiden Gestellwände 20 realisiert. Die Gestellwände 20 bilden mittels der Warteposition mithin einen Halteabschnitt für eine bewickelnde Wickelwelle 7.Furthermore, the fleece winder 1 comprises a recess on each frame wall 20 which defines a waiting position 3 for a winding shaft 7. Since the winding shafts are held on both sides by a respective frame wall 20, a waiting position 3 is thus implemented by means of the two frame walls 20. The frame walls 20 thus form a holding section for a winding shaft 7 by means of the waiting position.

In der Warteposition 3 wird die darin angeordnete Wickelwelle 7 mittels eines Andrehabschnitts 11 in Rotation versetzt. Der Andrehabschnitt 11 kontaktiert dabei den Bereich der Wickelwelle, der der Aufnahme von Vlies dient. D. h. nicht die gesamte Wickelwelle 7 wird in Rotation versetzt sondern nur deren hier mittig angeordneter somit Wickelabschnitt, der umfangsseitig die eigentliche Wickelfläche bildet.In the waiting position 3, the winding shaft 7 arranged therein is set in rotation by means of a turning section 11. The turning section 11 makes contact with the area of the winding shaft which is used to receive fleece. I. E. not the entire winding shaft 7 is set in rotation but only its winding section, which is arranged in the center here and which forms the actual winding surface on the circumferential side.

Um eine Wickelwelle vom Magazin 2 in die Warteposition 3 zu überführen, ist ein erster Transportabschnitt 9 vorgesehen.In order to transfer a winding shaft from the magazine 2 into the waiting position 3, a first transport section 9 is provided.

Ferner weist der Vlieswickler 1 eine Anwickelposition 4 auf, die sich in einem Knickbereich, gesehen entlang der Rotationsachse der Kontaktwalze 8 des Vlieswicklers 1, zwischen Gestellwand 20 und einer Kontaktwalze 8 befindet. Die Kontaktwalze 8 führt in bekannter Weise das hereinkommende Vlies an die zu bewickelnde Wickelwelle heran.Furthermore, the fleece winder 1 has a start-up position 4 which is located in a kink area, seen along the axis of rotation of the contact roller 8 of the fleece winder 1, between the frame wall 20 and a contact roller 8. The contact roller 8 leads the incoming fleece to the winding shaft to be wound in a known manner.

Zum automatischen Wechseln des Vlieses von einer Wickelwelle auf die nächste ist ein Trennabschnitt 12 vorgesehen, der einen hier nicht weiter bezeichneten Schneidabschnitt umfasst.For the automatic change of the fleece from one winding shaft to the next, a separating section 12 is provided, which comprises a cutting section not further designated here.

Ferner weist der Vlieswickler 1 eine Wickelposition 5 auf, die mittels eines hier links angeordneten Abschnitts zwischen Gestellwand 20 und Kontaktwalze 8 realisiert ist. In dieser Position 5 wird die entsprechende Wickelwelle, die bereits Vlies in der Anwickelposition 4 aufgenommen hat, endgültig bewickelt.Furthermore, the fleece winder 1 has a winding position 5, which is implemented by means of a section between the frame wall 20 and the contact roller 8 arranged here on the left. In this position 5, the corresponding winding shaft, which has already picked up fleece in the winding-on position 4, is finally wound.

Zum Transportieren hier der Wickelwelle 7 von der Warteposition 3 über die Anwickelposition 4 zur Wickelposition 5 wird ein Verriegelungs- und Bewegungsabschnitt 100 genutzt, der somit einen zweiten Transportabschnitt bildet.To transport the winding shaft 7 here from the waiting position 3 via the winding position 4 to the winding position 5, a locking and movement section 100 is used, which thus forms a second transport section.

Nach dem Bewickeln der jeweiligen Wickelwelle wird das Vlies mittels des Trennabschnitts 12 getrennt, und die bewickelte Wickelwelle wird mittels eines Wickel- und Ausschubabschnitts 10 in eine Ausschubposition 6 des Vlieswicklers 1 bewegt.After the winding of the respective winding shaft, the fleece is separated by means of the separating section 12, and the wound winding shaft is moved into an ejection position 6 of the fleece winder 1 by means of a winding and push-out section 10.

Jede Gestellwand 20 weist eine nach oben weisende Lauf- bzw. Führungsfläche 21 auf, die sich hauptsächlich von der Warteposition 3 zur Anwickelposition 4 erstreckt.Each frame wall 20 has an upwardly pointing running or guide surface 21, which extends mainly from the waiting position 3 to the winding position 4.

Figur 2 zeigt den Vlieswickler 1 hinsichtlich seines Verriegelungs- und Bewegungsabschnitts 100. Figure 2 shows the fleece winder 1 with regard to its locking and movement section 100.

Der Verriegelungs- und Bewegungsabschnitt 100 umfasst vorzugsweise an beiden Außenseiten der Gestellwände 20 Elemente, die dem Bewegen hier der Wickelwelle 7 von der Andrehposition 3 in die Anwickelposition 4 dienen.The locking and movement section 100 preferably comprises elements on both outer sides of the frame walls 20 which serve to move the winding shaft 7 from the starting position 3 to the starting position 4.

Diese Elemente umfassen jeweils einen Riemen 113, der um eine zugehöriges Paar von Riemenscheiben 116, 119 geschlungen ist. Mittels Rotierens der jeweiligen, hier nicht sichtbaren Riemenscheibe 116 wird ein zugehöriges Schwenkteil 120 mitrotiert. Eine Verbindungswelle 114 ist vorgesehen, beide Riemenscheiben 119, von denen nur die vordere sichtbar ist, miteinander bewegungszuverbinden.These elements each include a belt 113 that is looped around an associated pair of pulleys 116, 119. By rotating An associated swivel part 120 is rotated with the respective belt pulley 116, which is not visible here. A connecting shaft 114 is provided to movably connect both pulleys 119, of which only the front one is visible.

Die Verbindungswelle 114 ist durch beide Gestellwände 20 hindurchgehend mittels Drehlagern 22 in den Gestellwänden 20 frei rotierbar aufgenommen.The connecting shaft 114 is received in a freely rotatable manner in the frame walls 20 by means of pivot bearings 22, passing through both frame walls 20.

Ein Antriebsabschnitt 30 ist vorgesehen, mittels eines Motors 31 und hier eines Getriebes 32 über einen Riemen 33 eine vorzugsweise koaxial zur jeweiligen Riemenscheibe 116 angeordnete Riemenscheibe 34 anzutreiben, die drehfest zur Kontaktwalze 8, aber frei rotierbar in Bezug auf die Riemenscheibe 116, angeordnet ist.A drive section 30 is provided, by means of a motor 31 and here a gear 32 via a belt 33, to drive a belt pulley 34 which is preferably arranged coaxially to the respective belt pulley 116 and which is arranged non-rotatably relative to the contact roller 8, but freely rotatable with respect to the belt pulley 116.

Figur 3 zeigt den Vlieswickler 1 hinsichtlich dessen Verriegelungs- und Bewegungsabschnitts 100 von der in Figur 1 Rückseite her und ohne Antriebsabschnitt 30. Dadurch wird die in Richtung Kontaktwalze 8 dahinterliegende, benachbart angeordnete Riemenscheibe 116 sichtbar. Wie zu erkennen, ist die Anordnung im Wesentlichen die gleiche wie an der Vorderseite des Vlieswicklers 1 in Figur 2. Figure 3 FIG. 3 shows the web winder 1 with regard to its locking and movement section 100 from FIG Figure 1 The rear side and without the drive section 30. As a result, the adjacent belt pulley 116 located behind it in the direction of the contact roller 8 becomes visible. As can be seen, the arrangement is essentially the same as on the front side of the fleece winder 1 in FIG Figure 2 .

Abgesehen davon ist ein Antriebsabschnitt 110 vorgesehen, der im gezeigten Beispiel einen Motor 111 mit einem Getriebe 112 aufweist. Über das Getriebe 112 ist der Motor 111 in der Lage, die zugeordnete untere Umlenkrolle 119 in Rotation zu versetzen, um die der Riemen 113 geschlungen ist. Über die Verbindung zur Verbindungswelle 114 ist der Motor 111 damit in der Lage, den in Figur 2 dargestellten Verriegelungs- und Bewegungsabschnitt 100 ebenfalls in Bewegung zu versetzen.Apart from this, a drive section 110 is provided which, in the example shown, has a motor 111 with a gear 112. Via the transmission 112, the motor 111 is able to set the associated lower deflecting pulley 119 in rotation, around which the belt 113 is looped. Via the connection to the connecting shaft 114, the motor 111 is thus able to drive the in Figure 2 locking and moving section 100 shown to also set in motion.

Der Antriebsabschnitt 110 ist vorzugsweise vermittels eines Befestigungselements 101 an der hier dargestellten Gestellwand 20 befestigt.The drive section 110 is preferably fastened to the frame wall 20 shown here by means of a fastening element 101.

Der Verriegelungs- und Bewegungsabschnitt 100 umfasst dabei exemplarisch zwei Schwenkteile 120, die drehfest zu einer jeweiligen Riemenscheibe 116 angeordnet sind. Riemenscheibe 116 und Schwenkteil 120 können genauso gut einstückig miteinander ausgebildet sein.The locking and movement section 100 comprises two pivoting parts 120, which are arranged in a rotationally fixed manner with respect to a respective belt pulley 116. Belt pulley 116 and pivot part 120 can just as easily be formed in one piece with one another.

Figur 4 ist wiederum eine Darstellung von Figur 2 in größerem Detail und ohne Kontaktwalzen-Antriebsabschnitt 30. Hier ist zu erkennen, dass vorzugsweise eine Spannrolle 117 vorgesehen ist, um den Riemen 113 unter die notwendige Vorspannung zu setzen. Figure 4 is again a representation of Figure 2 in greater detail and without the contact roller drive section 30. It can be seen here that a tensioning roller 117 is preferably provided in order to put the belt 113 under the necessary pretension.

Figur 5 beinhaltet zwei vergrößerte Ansichten von Figur 4. Figure 5 includes two enlarged views of Figure 4 .

Im gezeigten Beispiel sind die Riemenscheibe 116 und das Schwenkteil 120 mittels Befestigungselementen 118 wie Schrauben aneinander befestigt. An dem Schwenkteil 120 ist ein Pneumatikzylinder 121 nebst einer Linearführung 123 befestigt. Die Linearführung 123 führt einen Schlitten 122 translatorisch von rechts nach links und zurück. An dem Schlitten 122 wiederum ist ein Verriegelungsabschnitt 130 befestigt.In the example shown, the belt pulley 116 and the pivoting part 120 are fastened to one another by means of fastening elements 118 such as screws. A pneumatic cylinder 121 together with a linear guide 123 is attached to the pivoting part 120. The linear guide 123 translates a slide 122 from right to left and back. A locking section 130 is in turn fastened to the slide 122.

Der Verriegelungsabschnitt 130 umfasst einen Pneumatikzylinder 131, der mit einem Ende seinem Kolben 132 abgewandten Ende an dem Schlitten 122 drehgelenkig befestigt ist. Das freie Ende des Kolbens 132 des Pneumatikzylinders 131 wiederum ist drehgelenkig an einem Verriegelungshebel 133 befestigt, der seinerseits ebenfalls drehgelenkig am Schlitten 122 befestigt ist.The locking section 130 comprises a pneumatic cylinder 131, which is attached to the slide 122 in a pivot-articulated manner with one end facing away from its piston 132. The free end of the piston 132 of the pneumatic cylinder 131 is in turn fastened in a pivot-joint manner to a locking lever 133, which in turn is also pivot-jointly fastened on the slide 122.

Mittels Herausfahrens des Kolbens 132 ist der Pneumatikzylinder 131 in der Lage, den Schwenkhebel 133 in Richtung Wickelwelle 7 zu bewegen, sodass mittels des Verriegelungsabschnitts 130 festgehalten wird.By moving out the piston 132, the pneumatic cylinder 131 is able to move the pivot lever 133 in the direction of the winding shaft 7, so that it is held by means of the locking section 130.

Der Pneumatikzylinder 121 ist über seinen hier nicht dargestellten Kolben in der Lage, den Schlitten 122 entlang der Linearführung 123 zu bewegen.The pneumatic cylinder 121 is able to move the slide 122 along the linear guide 123 via its piston (not shown here).

Soll die Wickelwelle 7 von der Warteposition 3 in die Anwickelposition 4 bewegt werden, wird mittels des hier nicht sichtbaren Antriebsabschnitts 110 der Riemen 113 so bewegt, dass die Riemenscheibe 116 hier entgegen dem Uhrzeigersinn rotiert wird. Damit wird nun die Anordnung Schwenkteil 120, Pneumatikzylinder 121, Linearführung 123 und Verriegelungsabschnitt 130 mitrotiert. Dabei rotiert der Verriegelungsabschnitt 130 zunächst um die Rotationsachse der Kontaktwalze 8.If the winding shaft 7 is to be moved from the waiting position 3 to the winding-on position 4, the belt 113 is moved by means of the drive section 110, which is not visible here, in such a way that the belt pulley 116 is rotated here counterclockwise. The arrangement of pivoting part 120, pneumatic cylinder 121, linear guide 123 and locking section 130 is now rotated with it. The locking section 130 initially rotates about the axis of rotation of the contact roller 8.

Um die Wickelwelle 7 in Kontakt mit oder sehr nahe der Lauffläche 21 der Gestellwand 20 zu halten bzw. zu führen, wird beim Verschwenken mittels des Pneumatikzylinders 121 bzw. mittels Einfahrens dessen Kolbens der Schlitten 122 nach und nach in Richtung Rotationsachse des Schwenkteils 120 entlang der Führung 123 bewegt. Nahe bedeutet dabei vorzugsweise im Millimeterbereich oder auch darunter.In order to keep or guide the winding shaft 7 in contact with or very close to the running surface 21 of the frame wall 20, when pivoting by means of the pneumatic cylinder 121 or by retracting its piston, the carriage 122 is gradually moved in the direction of the axis of rotation of the pivoting part 120 along the Guide 123 moves. Near means preferably in the millimeter range or below.

Figur 6 zeigt eine zu Figur 5 ähnliche Ansicht des Vlieswicklers 1, wenn sich die Wickelwelle 7 in Anwickelposition 4 befindet. Figure 6 shows one to Figure 5 Similar view of the fleece winder 1 when the winding shaft 7 is in the start-up position 4.

In der Anwickelposition 4 wird mittels bekannten Reibeschlusses zwischen Wickelwelle 7 und Kontaktwalze 8 das Vlies von der Kontaktwalze 8 auf die Wickelwelle 7 übertragen und damit die Wickelwelle 7 angewickelt.In the winding-on position 4, the fleece is transferred from the contact roller 8 to the winding shaft 7 by means of a known frictional connection between the winding shaft 7 and the contact roller 8, and the winding shaft 7 is thus wound on.

Ist die Wickelwelle 7 angewickelt, wird das Schwenkteil 120 gemäß Figur 6 weiter entgegen dem Uhrzeigersinn in Richtung Wickelposition 5 gedreht. Dabei wird im Rahmen der Linearführung 123 nunmehr darauf geachtet, dass die Wickelwelle 7 ständig in Kontakt mit der Kontaktwalze 8 steht.If the winding shaft 7 is wound, the pivoting part 120 is according to FIG Figure 6 turned further counterclockwise towards winding position 5. In the context of the linear guide 123, care is now taken to ensure that the winding shaft 7 is constantly in contact with the contact roller 8.

Befindet sich die Wickelwelle 7 in der Wickelposition 5, lässt der Verriegelungsabschnitt 130 die Wickelwelle 7 wieder los, und das Schwenkteil 120 wird in die entgegengesetzte Richtung, also im Uhrzeigersinn gemäß Figur 6, zurückgedreht, um die nächste, sich in Warteposition 3 befindliche Wickelwelle übernehmen zu können, wenn die sich nunmehr in Wickelposition 5 befindliche Wickelwelle 7 nahezu voll gewickelt ist und das Vlies auf eine neue Wickelwelle 7 zu übertragen ist.If the winding shaft 7 is in the winding position 5, the locking section 130 releases the winding shaft 7 again and the pivoting part 120 is rotated back in the opposite direction, i.e. clockwise according to FIG. 6, to take over the next winding shaft in waiting position 3 when the winding shaft 7, which is now in the winding position 5, is almost fully wound and the fleece is to be transferred to a new winding shaft 7.

Die Erfindung ist nicht auf die beschriebene Ausführungsform beschränkt.The invention is not restricted to the embodiment described.

Die Lauf- bzw. Führungsfläche 21 verläuft vorteilhafterweise kontinuierlich und ist vorzugsweise in der Form einer Umfangslinie eines Kreises bzw. einer Ellipse gebildet. Jedenfalls verringert sie ihren Abstand zum Boden, auf dem der Vlieswickler aufgestellt ist, zumindest in Richtung Warteposition 3 oder Anwickelposition 4.The running or guide surface 21 advantageously runs continuously and is preferably formed in the shape of a circumferential line of a circle or an ellipse. In any case, it reduces its distance from the floor on which the fleece winder is set up, at least in the direction of waiting position 3 or starting position 4.

Der Antriebsabschnitt 30 kann als Antriebsmittel auch einen Elektromotor aufweisen.The drive section 30 can also have an electric motor as a drive means.

Das gleiche gilt für den Pneumatikzylinder 121. Als Linearführung kommt beispielsweise ein vorzugsweise in Richtung Boden selbsthemmendes Schneckengetriebe infrage.The same applies to the pneumatic cylinder 121. A worm gear that is preferably self-locking in the direction of the bottom can be used as the linear guide.

Zudem kann eine Sensorik vorgesehen sein, um zu detektiere, wenn sich die Wickelwelle 7 in Warteposition 3, in Anwickelposition 4 und/oder in Wickelposition 5 befindet. Die Sensorik kann dabei optische Sensoren umfassen. Alternativ sind auch berührungssensitive Sensoren wie Schalter denkbar, die vorteilhafterweise von der jeweiligen Wickelwelle betätigt werden, wenn sie die jeweilige Position 3 - 5 erreichen.In addition, a sensor system can be provided in order to detect when the winding shaft 7 is in waiting position 3, in winding position 4 and / or in winding position 5. The sensor system can include optical sensors. Alternatively, touch-sensitive sensors such as switches are also conceivable, which are advantageously actuated by the respective winding shaft when they reach the respective position 3-5.

Als Verriegelungsabschnitt 130 kommt jede Art von Transportvorrichtung infrage, die in der Lage ist, eine Wickelwelle anzuheben. Sie kann beispielsweise elektromagnetisch ausgebildet sein.Any type of transport device that is capable of lifting a winding shaft can be used as the locking section 130. It can be designed electromagnetically, for example.

Der Schlitten 122 ist an der Linearführung 123 vorzugsweise mittels einer Schwalbenschwanzführung geführt aufgenommen.The slide 122 is received on the linear guide 123, preferably guided by means of a dovetail guide.

Die Riemenscheiben 34, 116 müssen nicht koaxial zueinander angeordnet sein.The pulleys 34, 116 do not have to be arranged coaxially with one another.

Die Riementriebe können einzeln oder insgesamt durch jedweden anderen Getriebemechanismus ersetzt sein.The belt drives can be replaced individually or as a whole by any other gear mechanism.

Im Ergebnis schafft die Erfindung eine einfache und kostengünstig zu realisierende Möglichkeit, eine Wickelwelle sicher zumindest von der Warteposition 3 in die Anwickelposition 4 zu bewegen.As a result, the invention creates a simple and cost-effective possibility of safely moving a winding shaft at least from the waiting position 3 into the winding-on position 4.
