Definitions

  • the invention relates to a device for a nonwoven winder, which is able to separate a nonwoven when changing the winding shaft to be wound.
  • the invention further relates to a nonwoven winder equipped with such a device and a method therefor.
  • Nonwoven winder are known per se. They serve to wind a fleece, for example coming out of a carding machine, onto a winding shaft.
  • empty winding shafts are automatically wound in succession. This is done by passing incoming nonwoven material around a rotating contact roll.
  • An empty winding shaft which is provided with an adhesive surface and rotates in the direction opposite to the contact roller, is placed against the contact roller and, due to the adhesion effect, takes over the nonwoven from the contact roller. If this winding shaft is full, a new, empty winding shaft is applied to the contact roller. At the moment, the still wound on the previous winding shaft fleece in the contact roller is separated. Thus, the web can be removed due to the adhesion effect with the free end of the empty winding shaft of the contact roller.
  • the cutting blade In order to separate the nonwoven, it is known to guide a rotating cutting blade along the axis of rotation of the contact roller along the nonwoven.
  • the axis of rotation of the cutting blade extends substantially perpendicular to the axis of rotation of the contact roller.
  • the cutting blade is housed in a frame which is arranged rotatable about the same axis as the contact roller. This frame is moved due to the subsequent, empty winding shaft in a single, coincident with the direction of rotation of the contact roller rotational direction.
  • the disadvantage is that the position the cutting blade is difficult to detect sensory.
  • the known electrically acting displacement sensors have the disadvantage that very expensive the required electrical lines must be performed from the outside to the respective displacement sensor. Contactless transmitting sensors are possible only by battery solution, which deteriorates the handling due to the necessary battery or battery change.
  • the object of the invention is to counteract these disadvantages.
  • a device which is designed to be integrated into a nonwoven winder so that the nonwoven winder is able to separate a nonwoven at a predetermined position during winding onto a first winding shaft by means of a separating section of the device.
  • the separating section comprises a cutting section.
  • the cutting section extends at least over a width of the fleece to be separated and is stationary with respect to a rotational axis of the contact roller or arranged to oscillate drivable by means of a drive of the cutting section.
  • the device has a holding section. This is arranged rotatable about an axis which coincides with the axis of rotation of the contact roller.
  • the device further comprises an actuating portion.
  • the operating portion is further configured to move the cutting portion between the first and a second state. In the second state, the cutting portion is so against a contact roller facing side of the nonwoven fabric, that the nonwoven is separated by means of the cutting section.
  • the device has a sensor. This is arranged to detect the presence of at least one of the states of the separation section. Due to the movement of the cutting device transversely to the axis of rotation of the contact roller can be dispensed with moving along the rotation axis, which makes a drive construction in this direction obsolete.
  • the movement transverse to the axis of rotation may involve a rotational movement and is also possible with pneumatic means due to the possible location stability along the axis of rotation.
  • the introduction of the drive medium (such as air) in a rotating part as the device according to the invention is possible by means of pneumatic connections to a non-rotating part of the web unwinder and transfer by means of pneumatic line structures cost.
  • the sensors can also be designed pneumatically, which also electrical leads can be omitted here. Last but not least, this increases operational safety due to the lack of danger of a short circuit.
  • the sensor has at least one sensor. This is arranged to be coupled via a connecting portion of the device with a control circuit of the nonwoven winder.
  • the connecting portion comprises a pivot bearing and a fixed bearing.
  • the fixed bearing in turn has a connection.
  • the connection is accessible from the outside with respect to the nonwoven winder to connect a first sensor line, and has an internal sensor line.
  • the pivot bearing is arranged stationary in relation to the holding section and designed to be rotatable in relation to the nonwoven winder arranged to be arranged. It also has a second sensor line. This is designed to be data transmitting at one end in each rotational position with the first sensor line and to be coupled to the sensor data transmitting at the other end. This is a secure data transfer between the rotating sensor and a controller, for example, the nonwoven winder realized, which serves the reliability.
  • the at least one sensor is preferably formed by means of an electronically and / or pneumatically acting sensor.
  • the sensor lines are accordingly electronic and / or pneumatic type.
  • An electronic sensor has the advantage of being able to pass signals unchanged to the controller.
  • For transmission to the non-rotating controller corresponding cable transmission components are known.
  • a pneumatic sensor has the advantage that instead of an electronic pneumatic signal transmission takes place. This is easily realized by means of pneumatically interconnected cavities on the rotary and fixed bearings. At the fixed bearing of the cavity, for example, circumferentially formed and is thus in each rotational position of the pivot bearing with the signal-transmitting cavity in combination.
  • the at least one sensor and the separating section may be arranged such that in the first or second state the separating section actuates the at least one sensor and in the second or first state an actuation of the at least one sensor by means of the separating section is avoided.
  • the sensor therefore detects only one of only two existing states in a purely technical manner. This simplifies the evaluation logic and ensures fewer errors, which benefits operational safety.
  • the at least one sensor and the separating section can be designed and arranged such that the actuation takes place without contact and / or mechanically.
  • the non-contact operation has the advantage of freedom from friction and thus wear independence.
  • the mechanical Operation allows the integration of very low-cost sensors, for example in the form of spring-loaded buttons. In both cases, existing moving parts can be integrated, which helps keep costs down.
  • Each of the aforementioned sensor systems preferably has a separate sensor for each drive element and / or the separation section. This has the advantage, on the one hand to be able to check the position of the separating section, and on the other hand its activation state. This increases the operational safety.
  • the separating section can be arranged rotatable or withdrawable in each of the aforementioned variants in the holding section.
  • the operating portion is accordingly configured to rotate the separating portion back and forth between the first and second states. These are particularly easy to implement movements to initiate the fleece separation.
  • the actuating portion may comprise an electric motor and / or a pneumatic cylinder.
  • the electric motor allows a particularly simple signal coupling
  • the pneumatic cylinder allows a particularly simple to be realized, pneumatic control line.
  • a nonwoven winder comprises one of the aforementioned devices. He is also adapted to wind on the first winding shaft a nonwoven by the nonwoven winder further comprises a contact roller and a pressure element.
  • the contact roller is rotatably driven.
  • the pressure element is adapted to press the first winding shaft against the contact roller and thereby guided the wound web around a partial circumference of the contact roller due to the friction between the contact roller and caused on the first winding shaft rotation on the first Wind up winding shaft.
  • the nonwoven winder is set up to separate the web and monitor the position of the cutting section by means of the device. The monitoring of the position of the cutting section has the advantage of always being in a defined state, which benefits operational safety.
  • the nonwoven winder preferably further comprises a conveying section. This is arranged, after separating the nonwoven a thus formed part fleece, which, as seen in the transport direction, before the separating section, to convey in the direction of a second winding shaft when it is detected by means of the sensor that the separating section is in the second state. This makes it possible to safely transfer the transfer of the separated, to be wound on the second winding shaft fleece on this winding shaft. In addition, it is ensured that the separating section occupies the separation position that is dangerous for users only at this particular changeover time.
  • a method of operating such a nonwoven winder comprises a step of winding an incoming nonwoven around the first winding shaft, a step of detecting the presence of a separation state in which the nonwoven is to be separated, and, in the presence of the separation state, a step of separating of the fleece. Finally, the method includes a step of detecting when the separation section is in the second state. If it is detected that the second state is present, ie at or immediately after separation of the nonwoven, the method comprises a step of conveying the partial nonwoven in the direction of a second winding shaft.
  • the device in this method, have an electronic or pneumatic sensor.
  • the method includes, at or immediately after conveying the sub-web, a step of moving the separating section to the first state.
  • the method comprises a step of moving the separating section away from the second winding shaft. This ensures that the danger to users is kept to a minimum over time. It also ensures that the second winding shaft can not be damaged by the separating section.
  • Each of the aforementioned methods may further comprise a step of detecting the presence of an activation state in which the device is to be activated.
  • the method provides a step of rotating the holding section into a separating position, such that the nonwoven is guided around a surface of the holding section facing away from the contact roller.
  • the method provides a step of rotating the holding section out of the separating position such that the web is freely movable past the holding section. This facilitates the transfer of the fleece by means of the second winding shaft.
  • FIG. 1 shows a nonwoven winder 1 according to an embodiment of the invention.
  • the components which are immaterial to the invention are not explained further.
  • the nonwoven winder 1 essentially comprises two frame walls 7, which are combined via non-designated connectors to form a frame which receives or holds all other functional elements of the nonwoven winder 1.
  • the frame walls 7 have in a right-hand area a magazine 2, in which two winding shafts 13, 14 are located by way of example here.
  • the nonwoven winder 1 comprises on each frame wall 7 a recess which defines a waiting position 3 for a winding shaft 15.
  • the winding shaft 15 on both sides of a respective frame wall. 7 is held, thus a waiting position 3 is realized by means of the two frame walls 7.
  • the frame walls 7 thus form a holding section for the winding shaft 15 to be wound by means of the waiting position 3.
  • the winding shaft 15 arranged therein is set in rotation by means of a clamping section 12.

Ein Schneidabschnitt (106) des Trennabschnitts (100) erstreckt sich über die Breite des Vlieses und ist in Bezug auf die Rotationsachse der Kontaktwalze (8) ortsfest oder oszillierend angetrieben, um die ein Halteabschnitt (130, 140) der Vorrichtung rotierbar angeordnet. Ein Betätigungsabschnitt (102, 104, 105) kann den Schneidabschnitt (106) im Halteabschnitt (130, 140) unterbringen, sodass der Schneidabschnitt (106) nicht mit dem Vlies in Kontakt gelangt. Der Abschnitt (102, 104, 105) kann den Schneidabschnitt (106) quer zur Rotationsachse der Vorrichtung so bewegen, dass der Schneidabschnitt (106) gegen das Vlies zum Trennen gedrängt wird. Eine Sensorik (160) der Vorrichtung dient dem Detektieren des Vorliegens zumindest eines dieser zwei Zustände des Trennabschnitts (100). Ein Vlieswickler (1) mit Vorrichtung kann mit einer Kontaktwalze (8) und einem Druckelement Vlies auf eine Wickelwelle wickeln. Das Druckelement drückt die Wickelwelle gegen die Kontaktwalze (8), um Vlies um einen Teilumfang der Kontaktwalze (8) herum geführt auf der Wickelwelle aufzuwickeln. Der Wickler kann das Vlies mittels der Vorrichtung trennen und die Position des Schneidabschnitts (106) überwachen. Ein Betriebsverfahren für den Vlieswickler (1) umfasst das Wickeln (S2) des Vlieses um die Wickelwelle, das Detektieren (S3) eines Trennzustands, wenn er vorliegt, das Trennen (S6) des Vlieses, das Detektieren, wenn der Schneidabschnitt gegen das Vlies gedrängt ist, und in dem Fall das Befördern (S7) des Teilvlieses in Richtung einer anderen Wickelwelle.A device is in a nonwoven winder (1) designed integrable, so that this fleece can separate with their device. A cutting section (106) of the separating section (100) extends across the width of the fleece and is driven stationary or oscillating with respect to the axis of rotation of the contact roller (8) about which a holding section (130, 140) of the device is rotatably arranged. An operating portion (102, 104, 105) can accommodate the cutting portion (106) in the holding portion (130, 140) so that the cutting portion (106) does not contact the nonwoven fabric.

Description

Die Erfindung betrifft eine Vorrichtung für einen Vlieswickler, die in der Lage ist, beim Wechsel der zu bewickelnden Wickelwelle ein Vlies aufzutrennen. Die Erfindung betrifft ferner einen mit solch einer Vorrichtung ausgestatteten Vlieswickler und ein Verfahren dafür.The invention relates to a device for a nonwoven winder, which is able to separate a nonwoven when changing the winding shaft to be wound. The invention further relates to a nonwoven winder equipped with such a device and a method therefor.

Vlieswickler an sich sind bekannt. Sie dienen dazu, ein beispielsweise aus einer Karde herauskommendes Vlies auf eine Wickelwelle aufzuwickeln. Dazu werden leere Wickelwellen im automatischen Wechsel nacheinander bewickelt. Dies erfolgt, indem ankommendes Vliesmaterial um eine rotierende Kontaktwalze herumgeführt wird. Eine mit einer adhäsiv wirkenden Oberfläche versehene und in zur Kontaktwalze entgegengesetzter Richtung rotierende, leere Wickelwelle wird an die Kontaktwalze angelegt und übernimmt aufgrund der Adhäsionswirkung das Vlies von der Kontaktwalze. Wird diese Wickelwelle voll, wird eine neue, leere Wickelwelle an die Kontaktwalze angelegt. In dem Moment wird das noch auf die vorherige Wickelwelle aufgewickelte Vlies im Bereich der Kontaktwalze getrennt. Damit kann das Vlies aufgrund der Adhäsionswirkung mit dem freien Ende von der leeren Wickelwelle von der Kontaktwalze abgenommen werden. Um das Vlies zu trennen, ist es bekannt, ein rotierendes Schneidmesser entlang der Rotationsachse der Kontaktwalze am Vlies entlang zu führen. Die Rotationsachse des Schneidmessers verläuft dabei im Wesentlichen senkrecht zur Rotationsachse der Kontaktwalze. Dabei ist das Schneidmesser in einem Rahmen untergebracht, der um dieselbe Achse rotierbar angeordnet ist wie die Kontaktwalze. Dieser Rahmen wird aufgrund der nachfolgenden, leeren Wickelwelle in eine einzige, mit der Rotationsrichtung der Kontaktwalze übereinstimmende Drehrichtung bewegt. Nachteilig ist, dass die Position des Schneidmessers nur schwer sensorisch zu erfassen ist. Zudem haben die bekanntermaßen elektrisch wirkenden Wegsensoren den Nachteil, dass sehr kostspielig die erforderlichen elektrischen Leitungen von außen zum jeweiligen Wegsensor geführt werden müssen. Kontaktlos übertragende Sensoren sind nur mittels Batterielösung möglich, was die Handhabbarkeit aufgrund des notwendigen Batterie- bzw. Akkuwechsels verschlechtert.Nonwoven winder are known per se. They serve to wind a fleece, for example coming out of a carding machine, onto a winding shaft. For this purpose, empty winding shafts are automatically wound in succession. This is done by passing incoming nonwoven material around a rotating contact roll. An empty winding shaft, which is provided with an adhesive surface and rotates in the direction opposite to the contact roller, is placed against the contact roller and, due to the adhesion effect, takes over the nonwoven from the contact roller. If this winding shaft is full, a new, empty winding shaft is applied to the contact roller. At the moment, the still wound on the previous winding shaft fleece in the contact roller is separated. Thus, the web can be removed due to the adhesion effect with the free end of the empty winding shaft of the contact roller. In order to separate the nonwoven, it is known to guide a rotating cutting blade along the axis of rotation of the contact roller along the nonwoven. The axis of rotation of the cutting blade extends substantially perpendicular to the axis of rotation of the contact roller. In this case, the cutting blade is housed in a frame which is arranged rotatable about the same axis as the contact roller. This frame is moved due to the subsequent, empty winding shaft in a single, coincident with the direction of rotation of the contact roller rotational direction. The disadvantage is that the position the cutting blade is difficult to detect sensory. In addition, the known electrically acting displacement sensors have the disadvantage that very expensive the required electrical lines must be performed from the outside to the respective displacement sensor. Contactless transmitting sensors are possible only by battery solution, which deteriorates the handling due to the necessary battery or battery change.

Aufgabe der Erfindung ist es, diesen Nachteilen zu begegnen.The object of the invention is to counteract these disadvantages.

Diese Aufgabe wird durch den Gegenstand der Ansprüche 1, 9 und 11 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen angegeben.This object is solved by the subject matter of claims 1, 9 and 11. Advantageous developments are specified in the subclaims.

Erfindungsgemäß ist eine Vorrichtung vorgesehen, die gestaltet ist, derart in einen Vlieswickler integriert zu werden, dass der Vlieswickler in der Lage ist, ein Vlies an einer vorbestimmten Position während des Aufwickelns auf eine erste Wickelwelle mittels eines Trennabschnitts der Vorrichtung zu trennen. Der Trennabschnitt umfasst einen Schneidabschnitt. Der Schneidabschnitt erstreckt sich zumindest über eine Breite des zu trennenden Vlieses und ist in Bezug auf eine Rotationsachse der Kontaktwalze ortsfest oder mittels eines Antriebs des Schneidabschnitts oszillierend antreibbar angeordnet. Die Vorrichtung verfügt über einen Halteabschnitt. Dieser ist um eine Achse rotierbar angeordnet, die mit der Rotationsachse der Kontaktwalze übereinstimmt. Die Vorrichtung umfasst ferner einen Betätigungsabschnitt. Dieser ist eingerichtet, den Schneidabschnitt in einem ersten Zustand so im Halteabschnitt unterzubringen, dass der Schneidabschnitt daran gehindert ist, mit dem Vlies in Kontakt zu gelangen. Der Betätigungsabschnitt ist ferner eingerichtet, den Schneidabschnitt zwischen dem erstem und einem zweiten Zustand zu bewegen. Im zweiten Zustand wird der Schneidabschnitt derart gegen eine der Kontaktwalze zugewandte Seite des Vlieses gedrängt, dass das Vlies mittels des Schneidabschnitts getrennt wird. Schließlich weist die Vorrichtung eine Sensorik auf. Diese ist eingerichtet, das Vorliegen zumindest eines der Zustände des Trennabschnitts zu detektieren. Aufgrund des Bewegens der Schneidvorrichtung quer zur Rotationsachse der Kontaktwalze kann auf das Bewegen entlang der Rotationsachse verzichtet werden, was eine Antriebskonstruktion in diese Richtung hinfällig macht. Die Bewegung quer zur Rotationsachse kann eine Drehbewegung beinhalten und ist aufgrund der möglichen Ortsfestigkeit entlang der Rotationsachse auch mit pneumatischen Mitteln möglich. Das Einleiten des Antriebsmediums (wie Luft) in ein rotierendes Teil wie die erfindungsgemäße Vorrichtung ist vermittels Pneumatikanschlüssen an einem nicht rotierenden Teil des Vlieswicklers und Überleitens mittels pneumatischer Leitungsstrukturen kostengünstig möglich. Die Sensorik kann ebenfalls pneumatisch ausgelegt werden, womit auch hier elektrische Zuleitungen entfallen können. Nicht zuletzt ist damit die Betriebssicherheit aufgrund der fehlenden Gefahr eines Kurzschlusses erhöht.According to the invention, a device is provided which is designed to be integrated into a nonwoven winder so that the nonwoven winder is able to separate a nonwoven at a predetermined position during winding onto a first winding shaft by means of a separating section of the device. The separating section comprises a cutting section. The cutting section extends at least over a width of the fleece to be separated and is stationary with respect to a rotational axis of the contact roller or arranged to oscillate drivable by means of a drive of the cutting section. The device has a holding section. This is arranged rotatable about an axis which coincides with the axis of rotation of the contact roller. The device further comprises an actuating portion. This is arranged to accommodate the cutting portion in a first state in the holding portion, that the cutting portion is prevented from coming into contact with the nonwoven. The operating portion is further configured to move the cutting portion between the first and a second state. In the second state, the cutting portion is so against a contact roller facing side of the nonwoven fabric, that the nonwoven is separated by means of the cutting section. Finally, the device has a sensor. This is arranged to detect the presence of at least one of the states of the separation section. Due to the movement of the cutting device transversely to the axis of rotation of the contact roller can be dispensed with moving along the rotation axis, which makes a drive construction in this direction obsolete. The movement transverse to the axis of rotation may involve a rotational movement and is also possible with pneumatic means due to the possible location stability along the axis of rotation. The introduction of the drive medium (such as air) in a rotating part as the device according to the invention is possible by means of pneumatic connections to a non-rotating part of the web unwinder and transfer by means of pneumatic line structures cost. The sensors can also be designed pneumatically, which also electrical leads can be omitted here. Last but not least, this increases operational safety due to the lack of danger of a short circuit.

Die Sensorik weist zumindest einen Sensor auf. Dieser ist eingerichtet, über einen Verbindungsabschnitt der Vorrichtung mit einer Steuerschaltung des Vlieswicklers gekoppelt zu werden. Der Verbindungsabschnitt umfasst dabei ein Drehlager und ein Festlager. Das Festlager wiederum weist einen Anschluss auf. Der Anschluss ist von außen in Bezug auf den Vlieswickler zugänglich, eine erste Sensorleitung anzuschließen, und weist eine inwendige Sensorleitung auf. Das Drehlager ist in Bezug auf den Halteabschnitt ortsfest angeordnet und in Bezug auf den Vlieswickler drehbar gelagert anordbar gestaltet. Es weist zudem eine zweite Sensorleitung auf. Diese ist gestaltet, einerends in jeder Rotationsstellung mit der ersten Sensorleitung datenübertragend gekoppelt zu sein und anderenends mit dem Sensor datenübertragend gekoppelt zu sein. Damit ist eine sichere Datenübertragung zwischen dem sich drehenden Sensor und einer Steuerung beispielsweise des Vlieswicklers realisierbar, was der Betriebssicherheit dient.The sensor has at least one sensor. This is arranged to be coupled via a connecting portion of the device with a control circuit of the nonwoven winder. The connecting portion comprises a pivot bearing and a fixed bearing. The fixed bearing in turn has a connection. The connection is accessible from the outside with respect to the nonwoven winder to connect a first sensor line, and has an internal sensor line. The pivot bearing is arranged stationary in relation to the holding section and designed to be rotatable in relation to the nonwoven winder arranged to be arranged. It also has a second sensor line. This is designed to be data transmitting at one end in each rotational position with the first sensor line and to be coupled to the sensor data transmitting at the other end. This is a secure data transfer between the rotating sensor and a controller, for example, the nonwoven winder realized, which serves the reliability.

Der zumindest eine Sensor ist vorzugsweise mittels eines elektronisch und/oder pneumatisch wirkenden Sensors gebildet. Die Sensorleitungen sind dementsprechend elektronischer und/oder pneumatischer Art. Ein elektronischer Sensor hat den Vorteil, Signale unverändert an die Steuerung weitergeben zu können. Zur Übertragung auf die sich nicht mitdrehende Steuerung sind entsprechende Kabelübertragungskomponenten bekannt. Ein pneumatisch ausgeführter Sensor hat den Vorteil, dass anstelle einer elektronischen eine pneumatische Signalübertragung erfolgt. Diese ist einfach vermittels miteinander pneumatisch verbundener Hohlräume am Dreh- und am Festlager realisierbar. Am Festlager ist der Hohlraum beispielsweise umlaufend ausgebildet und steht damit in jeder Rotationsstellung des Drehlagers mit dessen signalübertragendem Hohlraum in Verbindung.The at least one sensor is preferably formed by means of an electronically and / or pneumatically acting sensor. The sensor lines are accordingly electronic and / or pneumatic type. An electronic sensor has the advantage of being able to pass signals unchanged to the controller. For transmission to the non-rotating controller corresponding cable transmission components are known. A pneumatic sensor has the advantage that instead of an electronic pneumatic signal transmission takes place. This is easily realized by means of pneumatically interconnected cavities on the rotary and fixed bearings. At the fixed bearing of the cavity, for example, circumferentially formed and is thus in each rotational position of the pivot bearing with the signal-transmitting cavity in combination.

Alternativ oder zusätzlich kann der zumindest eine Sensor und der Trennabschnitt so angeordnet sein, dass im ersten oder zweiten Zustand der Trennabschnitt den zumindest einen Sensor betätigt und im zweiten bzw. ersten Zustand eine Betätigung des zumindest einen Sensors mittels des Trennabschnitts vermieden ist. Der Sensor detektiert rein technisch also nur einen von überhaupt nur zwei vorliegenden Zuständen. Dies vereinfacht die Auswertelogik und sorgt dabei für weniger Fehler, was der Betriebssicherheit zugutekommt.Alternatively or additionally, the at least one sensor and the separating section may be arranged such that in the first or second state the separating section actuates the at least one sensor and in the second or first state an actuation of the at least one sensor by means of the separating section is avoided. The sensor therefore detects only one of only two existing states in a purely technical manner. This simplifies the evaluation logic and ensures fewer errors, which benefits operational safety.

Dabei können der zumindest eine Sensor und der Trennabschnitt so ausgebildet und angeordnet sein, dass die Betätigung berührungsfrei und/oder mechanisch erfolgt. Die berührungsfreie Betätigung hat den Vorteil der Reibungsfreiheit und damit der Verschleißunabhängigkeit. Die mechanische Betätigung ermöglicht die Integration sehr preiswerter Sensoren beispielsweise in Form federbelasteter Taster. In beiden Fällen sind bereits vorhandene bewegliche Teile integrierbar, was Kosten niedrig halten hilft.In this case, the at least one sensor and the separating section can be designed and arranged such that the actuation takes place without contact and / or mechanically. The non-contact operation has the advantage of freedom from friction and thus wear independence. The mechanical Operation allows the integration of very low-cost sensors, for example in the form of spring-loaded buttons. In both cases, existing moving parts can be integrated, which helps keep costs down.

Jede der vorgenannten Sensoriken weist vorzugsweise für jedes Antriebselement und/oder den Trennabschnitt einen gesonderten Sensor auf. Dies hat den Vorteil, zum einen die Stellung des Trennabschnitts überprüfen zu können, und andererseits dessen Aktivierungszustand. Dies erhöht die Betriebssicherheit.Each of the aforementioned sensor systems preferably has a separate sensor for each drive element and / or the separation section. This has the advantage, on the one hand to be able to check the position of the separating section, and on the other hand its activation state. This increases the operational safety.

Der Trennabschnitt kann bei jeder der vorgenannten Varianten im Halteabschnitt drehbar oder herausfahrbar angeordnet sein. Der Betätigungsabschnitt ist dementsprechend gestaltet, den Trennabschnitt zwischen dem ersten und zweiten Zustand hin- und her zu drehen bzw. zu fahren. Dies sind besonders einfach zu realisierende Bewegungen, um die Vliestrennung einzuleiten.The separating section can be arranged rotatable or withdrawable in each of the aforementioned variants in the holding section. The operating portion is accordingly configured to rotate the separating portion back and forth between the first and second states. These are particularly easy to implement movements to initiate the fleece separation.

Dabei kann der Betätigungsabschnitt einen Elektromotor und/oder einen Pneumatikzylinder aufweisen. Der Elektromotor ermöglicht eine besonders einfache Signalkopplung, wohingegen der Pneumatikzylinder eine besonders einfach zu realisierende, pneumatische Ansteuerleitung ermöglicht.In this case, the actuating portion may comprise an electric motor and / or a pneumatic cylinder. The electric motor allows a particularly simple signal coupling, whereas the pneumatic cylinder allows a particularly simple to be realized, pneumatic control line.

Ein Vlieswickler weist erfindungsgemäß eine der vorgenannten Vorrichtungen auf. Er ist zudem eingerichtet, auf die erste Wickelwelle ein Vlies aufzuwickeln, indem der Vlieswickler ferner eine Kontaktwalze und ein Druckelement aufweist. Die Kontaktwalze ist drehbar angetrieben. Das Druckelement ist eingerichtet, die erste Wickelwelle gegen die Kontaktwalze zu drücken und dabei das aufzuwickelnde Vlies um einen Teilumfang der Kontaktwalze herum geführt aufgrund der Reibung zwischen der Kontaktwalze und der an der ersten Wickelwelle hervorgerufenen Rotation auf der ersten Wickelwelle aufzuwickeln. Der Vlieswickler ist schließlich eingerichtet, mittels der Vorrichtung, das Vlies zu trennen und die Position des Schneidabschnitts zu überwachen. Die Überwachung der Position des Schneidabschnitts hat den Vorteil, immer in einem definierten Zustand zu sein, was der Betriebssicherheit zugutekommt.A nonwoven winder according to the invention comprises one of the aforementioned devices. He is also adapted to wind on the first winding shaft a nonwoven by the nonwoven winder further comprises a contact roller and a pressure element. The contact roller is rotatably driven. The pressure element is adapted to press the first winding shaft against the contact roller and thereby guided the wound web around a partial circumference of the contact roller due to the friction between the contact roller and caused on the first winding shaft rotation on the first Wind up winding shaft. Finally, the nonwoven winder is set up to separate the web and monitor the position of the cutting section by means of the device. The monitoring of the position of the cutting section has the advantage of always being in a defined state, which benefits operational safety.

Der Vlieswickler weist vorzugsweise ferner einen Beförderungsabschnitt auf. Dieser ist eingerichtet, nach dem Trennen des Vlieses ein somit gebildetes Teilvlies, das sich, in Transportrichtung gesehen, vor dem Trennabschnitt befindet, in Richtung einer zweiten Wickelwelle zu befördern, wenn mittels der Sensorik detektiert ist, dass sich der Trennabschnitt im zweiten Zustand befindet. Dadurch ist es möglich, die Übergabe des abgetrennten, auf die zweite Wickelwelle aufzuwickelnden Vlieses sicher auf diese Wickelwelle zu übergeben. Zudem ist sichergestellt, dass der Trennabschnitt nur zu diesem jeweiligen Wechselzeitpunkt die für Benutzer gefährliche Trennposition einnimmt.The nonwoven winder preferably further comprises a conveying section. This is arranged, after separating the nonwoven a thus formed part fleece, which, as seen in the transport direction, before the separating section, to convey in the direction of a second winding shaft when it is detected by means of the sensor that the separating section is in the second state. This makes it possible to safely transfer the transfer of the separated, to be wound on the second winding shaft fleece on this winding shaft. In addition, it is ensured that the separating section occupies the separation position that is dangerous for users only at this particular changeover time.

Ein erfindungsgemäßes Verfahren zum Betreiben solch eines Vlieswicklers weist einen Schritt des Wickelns eines ankommenden Vlieses um die erste Wickelwelle, einen Schritt des Detektierens des Vorliegens eines Trennzustands, in dem das Vlies zu trennen ist, und, bei detektiertem Vorliegen des Trennzustands, einen Schritt des Trennens des Vlieses auf. Schließlich umfasst das Verfahren einen Schritt des Detektierens, wenn sich der Trennabschnitt im zweiten Zustand befindet. Ist detektiert, dass der zweite Zustand vorliegt, also bei oder unmittelbar nach erfolgtem Trennen des Vlieses, umfasst das Verfahren einen Schritt des Beförderns des Teilvlieses in Richtung einer zweiten Wickelwelle. Damit ist der Wechsel zwischen zwei Wickelwellen sicher durchgeführt, und dies mit verfahrenstechnisch geringem Aufwand.A method of operating such a nonwoven winder according to the present invention comprises a step of winding an incoming nonwoven around the first winding shaft, a step of detecting the presence of a separation state in which the nonwoven is to be separated, and, in the presence of the separation state, a step of separating of the fleece. Finally, the method includes a step of detecting when the separation section is in the second state. If it is detected that the second state is present, ie at or immediately after separation of the nonwoven, the method comprises a step of conveying the partial nonwoven in the direction of a second winding shaft. Thus, the change between two winding shafts is performed safely, and this with low process complexity.

Bei diesem Verfahren kann die Vorrichtung, wie vorstehend erläutert, über einen elektronischen bzw. pneumatischen Sensor verfügen. In dem Fall weist das Verfahren bei oder unmittelbar nach dem Befördern des Teilvlieses einen Schritt des Bewegens des Trennabschnitts in den ersten Zustand auf. Schließlich weist das Verfahren bei detektiertem Vorliegen des ersten Zustands mittels der Sensorik, einen Schritt des Wegbewegens des Trennabschnitts von der zweiten Wickelwelle weg auf. Dies stellt sicher, dass die Gefahr für Benutzer zeitlich auf ein Minimum begrenzt wird. Zudem wird sichergestellt, dass die zweite Wickelwelle nicht von dem Trennabschnitt beschädigt werden kann.In this method, the device, as explained above, have an electronic or pneumatic sensor. In that case, the method includes, at or immediately after conveying the sub-web, a step of moving the separating section to the first state. Finally, when the first state is detected by means of the sensor system, the method comprises a step of moving the separating section away from the second winding shaft. This ensures that the danger to users is kept to a minimum over time. It also ensures that the second winding shaft can not be damaged by the separating section.

Jedes der vorgenannten Verfahren kann ferner einen Schritt des Detektierens des Vorliegens eines Aktivierungszustands, in dem die Vorrichtung zu aktivieren ist, aufweisen. Bei detektiertem Vorliegen des Aktivierungszustands sieht das Verfahren einen Schritt des Drehens des Halteabschnitts in eine Trennposition vor, und zwar derart, dass das Vlies um eine der Kontaktwalze abgewandte Fläche des Halteabschnitts herumgeführt wird. Bei oder unmittelbar nach dem Befördern des Teilvlieses sieht das Verfahren einen Schritt des Drehens des Halteabschnitts aus der Trennposition heraus derart vor, dass das Vlies am Halteabschnitt frei vorbei bewegbar ist. Dies erleichtert die Vliesübernahme mittels der zweiten Wickelwelle.Each of the aforementioned methods may further comprise a step of detecting the presence of an activation state in which the device is to be activated. When the presence of the activation state is detected, the method provides a step of rotating the holding section into a separating position, such that the nonwoven is guided around a surface of the holding section facing away from the contact roller. During or immediately after conveying the partial web, the method provides a step of rotating the holding section out of the separating position such that the web is freely movable past the holding section. This facilitates the transfer of the fleece by means of the second winding shaft.

Figur 1 zeigt einen Vlieswickler 1 gemäß einer Ausführungsform der Erfindung. Die für die Erfindung unwesentlichen Bestandteile sind nicht weiter erläutert. FIG. 1 shows a nonwoven winder 1 according to an embodiment of the invention. The components which are immaterial to the invention are not explained further.

Der Vlieswickler 1 umfasst im Wesentlichen zwei Gestellwände 7, die über nicht bezeichnete Verbinder zu einem Gestell zusammengefasst sind, das alle anderen Funktionselemente des Vlieswicklers 1 aufnimmt bzw. hält.The nonwoven winder 1 essentially comprises two frame walls 7, which are combined via non-designated connectors to form a frame which receives or holds all other functional elements of the nonwoven winder 1.

Die Gestellwände 7 weisen in einem rechten Bereich ein Magazin 2 auf, in dem sich hier exemplarisch zwei Wickelwellen 13, 14 befinden.The frame walls 7 have in a right-hand area a magazine 2, in which two winding shafts 13, 14 are located by way of example here.

Weiterhin umfasst der Vlieswickler 1 an jeder Gestellwand 7 eine Ausnehmung, die eine Warteposition 3 für eine Wickelwelle 15 definiert. Da insbesondere die Wickelwelle 15 beidseitig von einer jeweiligen Gestellwand 7 gehalten wird, wird somit eine Warteposition 3 mittels der beiden Gestellwände 7 realisiert. Die Gestellwände 7 bilden mittels der Warteposition 3 mithin einen Halteabschnitt für die zu bewickelnde Wickelwelle 15.Furthermore, the nonwoven winder 1 comprises on each frame wall 7 a recess which defines a waiting position 3 for a winding shaft 15. In particular, the winding shaft 15 on both sides of a respective frame wall. 7 is held, thus a waiting position 3 is realized by means of the two frame walls 7. The frame walls 7 thus form a holding section for the winding shaft 15 to be wound by means of the waiting position 3.

In der Warteposition 3 wird die darin angeordnete Wickelwelle 15 mittels eines Andrehabschnitts 12 in Rotation versetzt. Der Andrehabschnitt 12 kontaktiert dabei den Bereich der Wickelwelle 15, der der Aufnahme von Vlies dient. D. h. nicht die gesamte Wickelwelle 15 wird in Rotation versetzt, sondern nur deren hier mittig angeordneter Abschnitt, der somit einen Wickelabschnitt und umfangsseitig die eigentliche Wickelfläche bildet.In the waiting position 3, the winding shaft 15 arranged therein is set in rotation by means of a clamping section 12. The Andrehabschnitt 12 contacts the area of the winding shaft 15, which serves to receive fleece. Ie. not the entire winding shaft 15 is set in rotation, but only their here centrally arranged portion which thus forms a winding portion and the circumference of the actual winding surface.

Um die einer Kontaktwalze 8 des Vlieswicklers 1 nächstliegende Wickelwelle (hier: 14) vom Magazin 2 in die Warteposition 3 zu überführen, ist ein Transportabschnitt 9 vorgesehen.In order to transfer the winding shaft (here: 14) closest to a contact roller 8 of the nonwoven winder 1 from the magazine 2 to the waiting position 3, a 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, zwischen Gestellwand 7 und Kontaktwalze 8 befindet. Die Kontaktwalze 8 führt in bekannter Weise das hereinkommende Vlies an die zu bewickelnde Wickelwelle heran.Furthermore, the nonwoven winder 1 has a Anwickelposition 4, which is located in a bending region, as seen along the axis of rotation of the contact roller 8, between the frame wall 7 and contact roller 8. The contact roller 8 leads in a known manner, the incoming fleece zoom to be wound on the winding shaft.

Zum automatischen Wechseln des Vlieses von einer Wickelwelle (hier: 16) auf die nächste, sich in Anwickelposition 4 befindliche Wickelwelle ist ein Trennabschnitt 100 vorgesehen, der einen hier nicht weiter bezeichneten Schneidabschnitt umfasst.For automatically changing the web of a winding shaft (here: 16) to the next, located in Anwickelposition 4 winding shaft, a separating portion 100 is provided which includes a cutting section not further described here.

Ferner weist der Vlieswickler 1 eine Wickelposition 5 auf, die mittels eines hier links angeordneten Abschnitts zwischen Gestellwand 7 und Kontaktwalze 8 realisiert ist. In dieser Position 5 wird die entsprechende Wickelwelle (hier: 16), die bereits Vlies in der Anwickelposition 4 aufgenommen hat, endgültig bewickelt.Furthermore, the nonwoven winder 1 has a winding position 5, which by means of a section arranged here on the left between frame wall 7 and contact roller 8 is realized. In this position 5, the corresponding winding shaft (here: 16), which has already taken up fleece in the Anwickelposition 4, finally wound.

Zum Transportieren beispielsweise der Wickelwelle 14 von der Warteposition 3 über die Anwickelposition 4 zur Wickelposition 5 wird ein Verriegelungs- und Bewegungsabschnitt 10 genutzt.To transport, for example, the winding shaft 14 from the waiting position 3 via the Anwickelposition 4 to the winding position 5, a locking and moving portion 10 is used.

Nach dem Bewickeln hier der Wickelwelle 16 wird das Vlies mittels des Trennabschnitts 100 getrennt, und die bewickelte Wickelwelle 16 wird mittels eines Wickel- und Ausschubabschnitts 11 in eine Ausschubposition 6 des Vlieswicklers 1 bewegt (dargestellt mittels der Wickelwelle 17).After winding here the winding shaft 16, the web is separated by means of the separating section 100, and the wound winding shaft 16 is moved by means of a winding and Ausschubabschnitts 11 in a Ausschubposition 6 of the web unwinder 1 (shown by the winding shaft 17).

Figur 2 zeigt den Vlieswickler 1 im Rahmen des Trennabschnitts 100 in größerem Detail und in zwei Ansichten. FIG. 2 shows the nonwoven winder 1 in the context of the separating section 100 in greater detail and in two views.

Der Vlieswickler 1 zeigt den Trennabschnitt 100 und die beiden für die Aufnahme nicht dargestellten Wickelwellen vorgesehenen Gestellwände 7. der Trennabschnitt 100 umfasst einen Gehäuseabschnitt 140, der alle zum Trennen des Vlieses notwendigen Bestandteile aufnimmt. An beiden stirnseitigen Enden ist der Gehäuseabschnitt 140 mittels eines jeweiligen Schwenkteils 130 abgeschlossen. Jedes der Schwenkteile 130 ist dabei um eine Rotationsachse schwenkbar bzw. rotierbar angeordnet, die mit der Rotationsachse der Kontaktwalze 8 übereinstimmt.The nonwoven winder 1 shows the separating section 100 and the two frame walls 7 provided for the take-up shafts, not shown for the receptacle. The separating section 100 comprises a housing section 140, which receives all the components necessary for separating the nonwoven. At both ends, the housing section 140 is closed by means of a respective pivoting part 130. Each of the pivoting parts 130 is arranged pivotable or rotatable about a rotation axis, which coincides with the axis of rotation of the contact roller 8.

Um das Schwenkteil 130 zu rotieren, ist ein Antriebsabschnitt 120 vorgesehen. Dieser umfasst hier an nur einer Außenseite einer Gestellwand 7 (hier: der vorderen) ein Modul, gebildet mittels eines Motors 121, eines abtriebsseitig angeordneten Getriebes 122 und eines Befestigungsteils 127, über das die Motor-Getriebe-Einheit 121, 122 an der Gestellwand 7 befestigt ist. Abtriebsseitig ist das Getriebe 122 mit einer Welle 128 rotationswirkverbunden. Deren Rotationsachse verläuft parallel zur Rotationsachse der Kontaktwalze 8. An den hier einander gegenüberliegenden Innenseiten der Gestellwände 7 ist auf der Welle 128 jeweils eine Riemenscheibe 125 drehfest angebracht bzw. einstückig mit der Welle 128 ausgebildet.In order to rotate the pivot part 130, a drive section 120 is provided. This comprises here on only one outer side of a frame wall 7 (here: the front) a module formed by a motor 121, a driven side arranged gear 122 and a fixing member 127, via which the motor-gear unit 121, 122 on the frame wall is attached. On the output side, the gear 122 is rotationally connected to a shaft 128. Their rotation axis is parallel to the axis of rotation of the contact roller 8. At the opposite sides of the frame walls 7 here on the shaft 128 each have a pulley 125 rotatably mounted or integrally formed with the shaft 128.

Um jede dieser Riemenscheiben 125 ist ein Riemen 123 geschlungen, der zudem um eine jeweils zweite Riemenscheibe 126 geschlungen ist. Jede Riemenscheibe 126 ist an einem jeweils zugehörigen der zwei Schwenkteile 130 befestigt oder einstückig mit diesem ausgebildet. Damit ist es dem Motor 121 möglich, über das hier einen Riementrieb aufweisende Getriebe das jeweilige Schwenkteil 130 und damit das Gehäuseabschnitt 140 mit den darin angeordneten Funktionselementen in Rotation zu versetzen.To each of these pulleys 125, a belt 123 is wound, which is also wrapped around a respective second pulley 126. Each pulley 126 is fixed to or integrally formed with a respective one of the two swing members 130. This makes it possible for the motor 121 to set the respective pivoting part 130 and thus the housing section 140 with the functional elements arranged therein into rotation via the gearbox having a belt drive here.

Dabei ist vorgesehen, dass der Trennabschnitt 100 bzw. der Gehäuseabschnitt 140 gemäß Figur 2a nur im Uhrzeigersinn gedreht wird. Da das Vlies beim Wickeln oberhalb der Kontaktwalze 8 verläuft, erfasst der Gehäuseabschnitt 140 beim Rotieren das Vlies, von links kommend, von der in Figur 2a Unterseite her und drückt es somit nach oben von der Kontaktwalze 8 weg, wenn er in die in Figur 2a gezeigte (Trenn-)Position gedreht wird.It is provided that the separating section 100 or the housing section 140 in accordance with FIG. 2a only turned clockwise. Since the fleece during winding runs above the contact roller 8, the housing section 140 detects during rotation the fleece, coming from the left, from the underside in FIG. 2a and thus pushes it upwards away from the contact roller 8, when it moves into the infeed roller FIG. 2a shown (separation) position is rotated.

Figur 2b zeigt die gleiche Anordnung von der in Figur 2a Rückseite der hinteren Gestellwand 7 aus gesehen. Die Welle 128 ist in den Gestellwänden 7 mittels Drehlagern 124 frei rotierbar aufgenommen. Ferner ist zu erkennen, dass auf der in Figur 2b Außenseite der vorderen Gestellwand 7 kein Antriebsmittel in Form eines Motors oder dergleichen vorhanden ist. D. h. ein einziger Motor 121 bewegt den gesamten Rest des Trennabschnitts 100. FIG. 2b shows the same arrangement of the in FIG. 2a Rear side of the rear frame wall 7 seen from. The shaft 128 is freely rotatably received in the frame walls 7 by means of pivot bearings 124. It can also be seen that on the in FIG. 2b Outside the front frame wall 7 no drive means in the form of a motor or the like is present. Ie. a single motor 121 moves the entire remainder of the separation section 100.

Figur 3 zeigt eine Detailansicht des Trennabschnitts 100 des Vlieswicklers 1. FIG. 3 shows a detailed view of the separating portion 100 of the nonwoven winder 1.

Beide Schwenkteile 130 umfassen in einem hier unteren Bereich eine beispielhaft kreisförmige Ausnehmung 131, um die hier nicht dargestellte Kontaktwalze 8 frei rotierbar zu umgreifen.Both pivoting parts 130 comprise, in a lower region here, an exemplary circular recess 131 in order to engage around the contact roller 8, not shown here, in a freely rotatable manner.

Ferner sind hier fünf Befestigungsabschnitte 109 beispielsweise in Form von Schrauben vorgesehen, mittels denen das jeweilige Schwenkteil 130 mit seiner dem Gehäuseabschnitt 140 abgewandten Außenseite an der zugehörigen, hier nicht dargestellten Riemenscheibe 126 befestigt ist.Furthermore, five fastening sections 109 are provided here, for example in the form of screws, by means of which the respective pivoting part 130 is fastened with its outer side facing away from the housing section 140 to the associated pulley 126 (not illustrated here).

Mithin bildet die Außenseite des jeweiligen Schwenkteils 130 vorteilhafterweise eine Absicherung, dass der Riemen 123 nicht in Richtung Schwenkteil 123 abrutschen kann. Die jeweils zugehörige Gestellwand 7 sorgt dafür, dass der Riemen 123 auch nicht in die andere Richtung von der Riemenscheibe 126 abrutschen kann. Somit sind die Riemen 123 sicher geführt.Consequently, the outside of the respective pivoting part 130 advantageously forms a safeguard that the belt 123 can not slip in the direction of the pivoting part 123. The respective associated frame wall 7 ensures that the belt 123 can not slip off in the other direction of the pulley 126. Thus, the belts 123 are guided safely.

Der Gehäuseabschnitt 140 besteht im Wesentlichen aus zwei Gehäuseteilen 141,142.The housing section 140 consists essentially of two housing parts 141, 142.

Diese sind an den Schwenkteilen 130 und/oder aneinander befestigt.These are attached to the pivoting parts 130 and / or each other.

Beide Schwenkteile 130 sind so ausgebildet und zueinander angeordnet, dass deren Durchgangsöffnungen 132, entlang der Rotationsachse der Schwenkteile 130 gesehen, miteinander fluchten. In diese ist eine später näher erläuterte Welle 151 mit einem jeweiligen Ende frei rotierbar aufgenommen.Both pivoting parts 130 are designed and arranged relative to one another such that their passage openings 132, viewed along the axis of rotation of the pivoting parts 130, are aligned with one another. In this, a later explained in more detail shaft 151 is freely rotatably received with a respective end.

Ferner gibt es zwei von zwei Befestigungsabschnitten 109 in Form von Senkkopfschrauben verdeckte, nicht bezeichnete Befestigungsöffnungen.Further, there are two mounting holes concealed by two fixing portions 109 in the form of countersunk screws, not designated.

Schließlich ist ein ebenfalls nachstehend näher erläutertes Schneidabschnitt 106 gezeigt.Finally, a likewise explained in more detail below cutting section 106 is shown.

Figur 4 zeigt eine Ansicht des Trennabschnitts 100 ohne Schwenkteil 130 und mit Kontaktwalze 8. Dadurch ist das Innere des Gehäuses 140 zu erkennen. FIG. 4 shows a view of the separating section 100 without pivoting part 130 and with contact roller 8. Thus, the interior of the housing 140 can be seen.

An dem hier dargestellten vorderen Ende des Gehäuses 140 ist an dem Gehäuseteil 142 ein Befestigungselement 101 angebracht, an dem ein Pneumatikzylinder 102 einerends drehbar angelenkt ist. Das freie Ende des Kolbens 103 dieses Pneumatikzylinders 102 ist drehgelenkig an einem Schwenkteil 104 angebracht. Das Schwenkteil 104 ist anderenends an einer Welle 105 bzw. einem später näher beschriebenen Übertragungselement 108 drehfest angeordnet. Mittels Einziehens des Kolben 103 ist der Pneumatikzylinder 102 in der Lage, das Schwenkteil 104 hier entgegen dem Uhrzeigersinn um die mittels der Welle 105 definierte Rotationsachse zu verschwenken. Ferner weist das Gehäuseteil 142 hier an der rechten Seite mehrere Durchgangsöffnungen 144 auf, die es ermöglichen, dass ein jeweiliges Blaselement 152 Luft nach außen in Bezug auf den Gehäuseabschnitt 140 ausblasen kann. Die Funktion des Blaselements 152 wird später näher erläutert. Das Blaselement 152 ist mittels eines Befestigungselements 153 drehfest auf der Welle 151 angebracht.At the front end of the housing 140 shown here, a fastening element 101 is attached to the housing part 142, to which a pneumatic cylinder 102 is pivotally hinged at one end. The free end of the piston 103 of this pneumatic cylinder 102 is pivotally mounted on a pivot member 104. The pivoting part 104 is at the other end rotatably arranged on a shaft 105 and a transmission element 108 described in more detail below. By retracting the piston 103, the pneumatic cylinder 102 is capable of pivoting the pivoting part 104 counterclockwise about the axis of rotation defined by the shaft 105. Furthermore, the housing part 142 here on the right side on a plurality of through holes 144, which allow that a respective blowing element 152 can blow out air with respect to the housing portion 140. The function of the blowing element 152 will be explained later. The blowing element 152 is fixedly mounted on the shaft 151 by means of a fastening element 153.

Ferner ist hier ein Lagerelement 143 angeordnet, das die Welle 151 zwischen deren Enden frei rotierbar aufnimmt, sodass die Welle 151 über ihre Länge nicht durchbiegen kann. Vorzugsweise ist das Lagerelement 143 auch in der Lage, die jeweilige Welle 105 frei rotierbar gelagert aufzunehmen. Im gezeigten Ausführungsbeispiel ist dies allerdings nicht der Fall, wie später näher erläutert.Further, here is a bearing element 143 is arranged, which receives the shaft 151 freely rotatable between the ends, so that the shaft 151 can not bend over its length. Preferably, the bearing element 143 also able to receive the respective shaft 105 freely rotatably mounted. In the embodiment shown, however, this is not the case, as explained in more detail later.

Der Gehäuseabschnitt 140 bzw. im gezeigten Beispiel das Gehäuseteil 142 weist an der der Kontaktwalze 8 abgewandten Seite eine Durchgangsöffnung bzw. eine Ausnehmung 145 auf, deren Funktion später näher erläutert wird.The housing section 140 or, in the example shown, the housing part 142 has, on the side facing away from the contact roller 8, a passage opening or a recess 145, the function of which will be explained in more detail later.

Figur 5 zeigt eine ausschnittsweise Innenansicht des Trennabschnitts 100 ohne Gehäuseabschnitt 140. Der Trennabschnitt 100 ist dabei im Bereich des in Figur 3 und Figur 4 vorderen Endes im Ausschnitt dargestellt. FIG. 5 shows a partial interior view of the separating portion 100 without housing portion 140. The separating portion 100 is in the range of in FIG. 3 and FIG. 4 shown in the neckline at the front.

Deutlich sind der Pneumatikzylinder 102 sowie das Befestigungselement 101 zu erkennen, das über Befestigungsabschnitte 109 hier in Form jeweils einer Schraube und einer Mutter an dem hier nicht dargestellten Gehäuseteil 142 ortsfest angebracht ist. Die Welle 105 ist am freien, hier rechten Ende mittels eines Drehlagers 111 in einem zugehörigen Befestigungselement 110 frei rotierbar aufgenommen. Dieses ist mittels der in Bezug auf Figur 3 angegebenen zwei Befestigungsabschnitte 109 in Form von Senkkopfschrauben durch die vorstehend angegebenen Befestigungsöffnungen im jeweiligen Schwenkteil 130 durchgehend an diesem angebracht. Das Schwenkteil 104 ist vorzugsweise an dem vorstehend erwähnten, im Querschnitt hier exemplarisch viereckigen Übertragungselement 108 angebracht oder einstückig mit diesem ausgebildet. Die Welle 105 greift vorzugsweise mit ihrem dem Übertragungselement zugewandten Ende form- bzw. kraftschlüssig in das Übertragungselement 108 ein, kann aber auch einstückig mit dem Übertragungselement 108 ausgebildet sein.Significantly, the pneumatic cylinder 102 and the fastener 101 can be seen, which is attached via mounting portions 109 here in the form of a respective screw and a nut on the housing part 142, not shown here stationary. The shaft 105 is freely rotatably received at the free, here right end by means of a rotary bearing 111 in an associated fastener 110. This is by means of in relation to FIG. 3 indicated two mounting portions 109 in the form of countersunk screws through the above-mentioned mounting holes in the respective pivot member 130 continuously attached thereto. The pivoting part 104 is preferably attached to the above-mentioned, in cross-section here exemplary square-shaped transmission element 108 or integrally formed therewith. The shaft 105 preferably engages with its end facing the transmission element positively or non-positively in the transmission element 108, but may also be integrally formed with the transmission element 108.

Über den Kolben 103 ist der Pneumatikzylinder 102 in der Lage, mittels Verschwenkens des Schwenkteils 104 das Übertragungselement 108 und gegebenenfalls auch die Welle 105 um eine Rotationsachse parallel zur Rotationsachse der Kontaktwalze 8 zu rotieren.By means of the piston 103, the pneumatic cylinder 102 is able to rotate the transmission element 108 and optionally also the shaft 105 about an axis of rotation parallel to the axis of rotation of the contact roller 8 by pivoting the pivoting part 104.

An dem Übertragungselement 108 ist ferner der Schneidabschnitt 106 befestigt, der an seiner hier oberen Seite eine Verzahnung aufweist. Die Verzahnung ist so gestaltet, dass sie bei Kontakt ein Vlies auftrennen kann.On the transmission element 108 of the cutting portion 106 is further attached, which has a toothing on its upper side here. The toothing is designed so that it can break a fleece on contact.

Wird der Kolben 103 eingezogen, wird der Schneidabschnitt 106 in Figur 3 entgegen dem Uhrzeigersinn nach außen durch die vorgenannte Ausnehmung 145 hindurch nach außen aufgeklappt, sodass die hier zackenartige Verzahnung des Schneidabschnitts 106 aus dem Gehäuseabschnitt 140 herausragt.When the piston 103 is retracted, the cutting portion 106 in FIG. 3 counterclockwise outwardly through the aforementioned recess 145 through outwardly unfolded, so that here the serrated teeth of the cutting portion 106 protrudes from the housing portion 140.

Ferner ist das Blaselement 152 gezeigt, das mittels eines zugehörigen Befestigungselements 153 auf der Welle 151 befestigt ist, die ihrerseits vorzugsweise im Schwenkteil 130 frei rotierbar gelagert ist. Die Befestigung erfolgt wiederum mittels hier zweier Befestigungsabschnitte 109 in Form jeweils einer Schraube und einer Mutter. Klappt der Pneumatikzylinder 102 den Schneidabschnitt 106 aus dem Gehäuseabschnitt 140 heraus, wird somit das daran anliegende Vlies getrennt, und das Blaselement 152, das vorzugsweise mehrfach vorgesehen über die gesamte Breite des Vlieses verteilt angeordnet ist, lässt Luft durch die in Figur 4 angegebenen Durchgangsöffnungen 144 aus dem Gehäuseabschnitt 140 austreten. Dadurch wird das abgetrennte Vlies in Richtung der neu zu bewickelnden, leeren Wickelwelle, die sich in Anwickelposition 4 befindet, befördert. Die Welle 151, das bzw. die Blaselemente 152 und das bzw. die Befestigungselemente 153 bilden mithin einen Beförderungsabschnitt 150.Furthermore, the blowing element 152 is shown, which is fastened by means of an associated fastening element 153 on the shaft 151, which in turn is preferably freely rotatably mounted in the pivoting part 130. The attachment is again by means of two attachment portions 109 in the form of a screw and a nut. If the pneumatic cylinder 102 folds out the cutting section 106 from the housing section 140, the fleece lying against it is thus separated, and the blowing element 152, which is preferably arranged distributed over the entire width of the fleece, allows air to flow through the fleece FIG. 4 indicated through holes 144 exit from the housing portion 140. As a result, the separated fleece is conveyed in the direction of the new winding shaft to be wound, which is in the winding position 4. The shaft 151, the blowing element (s) 152 and the fastening element (s) 153 thus form a conveying section 150.

Um steuerungstechnisch erfassen bzw. detektieren zu können, in welchem Zustand sich der Schneidabschnitt 106 befindet (ein- oder ausgeklappt), ist ein Sensor 160 vorgesehen. Dieser ist im gezeigten Fall mechanisch ausgebildet. Er umfasst ein Gehäuse 163, das mittels hier zweier Befestigungsabschnitte 109 an einem Befestigungselement 145 befestigt ist. Das Befestigungselement 145 seinerseits ist an der hier nach unten weisenden Seite mittels ebenfalls zweier Befestigungsabschnitte 109 vorzugsweise in Form jeweils einer Schraube und einer Mutter nunmehr an dem nicht abgebildeten Gehäuseteil 141 befestigt oder auch mit diesem einstückig ausgebildet.In order to be able to detect or detect control technology in which state the cutting section 106 is located (folded or unfolded), a sensor 160 is provided. This is mechanically formed in the case shown. It comprises a housing 163, which is fastened to a fastening element 145 by means of two fastening sections 109 here. The fastening element 145 in turn is attached to the here downwardly facing side by means of two fastening sections 109, preferably in the form of a screw and a nut now on the housing part not shown 141 or formed integrally therewith.

Der Sensor 160 weist an seiner dem Gehäuseteil 141 abgewandten Seite einen zweiarmigen Hebel 162 auf, an dessen freien Ende eine Tastrolle 161 vorzugsweise frei rotierbar angeordnet ist. Die Rotationsachse der Tastrolle 161 verläuft exemplarisch parallel zur Rotationsachse der Welle 105. An dem Übertragungselement 108 ist ein Betätigungselement 107 in Form eines hier plattenartigen Teils wiederum mittels zweier Befestigungsabschnitte 109, exemplarisch gebildet mittels jeweils einer Schraube und einer Mutter, so ortsfest angebracht, dass es in den Schwenkweg der Tastrolle 161 hineinragt. Im in Figur 5 gezeigten Zustand drängt das Betätigungselement 107 die Tastrolle 161 in Richtung Gehäuseabschnitt 163 und betätigt damit den Sensor 160. Wird der Schneidabschnitt 106 ausgeklappt, verschwenkt das Betätigungselement 107 gemäß Figur 5 im Uhrzeigersinn von der Tastrolle 161 weg und entlastet damit die vorzugsweise federnd gelagerte Hebelanordnung 162. Damit wird die Betätigung des Sensors 160 aufgehoben. So kann detektiert werden, dass sich das Schneidabschnitt 106 nunmehr im Ausklappzustand befindet, in dem Vlies getrennt werden kann.The sensor 160 has on its side facing away from the housing part 141 a two-armed lever 162, at the free end of a sensing roller 161 is preferably arranged freely rotatable. The axis of rotation of the follower roller 161 runs as an example parallel to the axis of rotation of the shaft 105. On the transmission element 108, an actuating element 107 in the form of a plate-like part in turn by means of two mounting portions 109, exemplified formed by a respective screw and a nut so fixedly mounted that it protrudes into the pivoting of the feeler roller 161. Im in FIG. 5 As shown, the actuating element 107 urges the follower roller 161 in the direction of the housing section 163 and thus actuates the sensor 160. If the cutting section 106 is unfolded, the actuating element 107 pivots according to FIG FIG. 5 clockwise away from the follower roller 161 and thus relieves the preferably spring-mounted lever assembly 162. Thus, the operation of the sensor 160 is released. Thus, it can be detected that the cutting section 106 is now in the unfolded state in which the nonwoven can be separated.

Der Sensor 160 ist vorzugsweise als Öffner ausgebildet. Dies bedeutet, dass er gemäß Figur 5 einen Stromkreis öffnet, sodass kein Strom verbraucht wird. Eine Steuerschaltung außerhalb des Trennabschnitts 100 registriert das Sensorsignal und schaltet beispielsweise das bzw. die Blaselemente 152 zu oder wieder ab.The sensor 160 is preferably designed as an opener. This means that he according to FIG. 5 opens a circuit so that no power is consumed. A control circuit outside of the separation section 100 registers the sensor signal and, for example, switches the blower element 152 on or off again.

Alternativ ist der Sensor 160 pneumatisch ausgebildet. D. h. er ist über eine hier nicht dargestellte pneumatische Leitung nach außen in Bezug auf den Trennabschnitt 100 aus diesem herausgeführt. Eine pneumatische Leitung hat den Vorteil, dass der Sensor 160 in jeder Rotationsposition der Welle 105 in Bezug auf den Gehäuseabschnitt 140 bzw. auf die Gestellwand 107 mittels eines ringartigen Kanals nach außen hin pneumatisch einfach angeschlossen werden kann. Bei einem elektrischen Sensor 161 müsste eine relativ teure bzw. verschleißanfällige Lösung beispielsweise mittels Schleifkontakten realisiert werden, um in jeder Rotationsstellung den elektrischen Kontakt zu gewährleisten.Alternatively, the sensor 160 is pneumatically formed. Ie. it is led out via a pneumatic line, not shown here in relation to the separating section 100 out of this. A pneumatic line has the advantage that the sensor 160 in any rotational position of the shaft 105 with respect to the housing portion 140 and on the frame wall 107 by means of a ring-like channel to the outside pneumatically easily connected. In the case of an electrical sensor 161, a relatively expensive or wear-prone solution would have to be realized, for example, by means of sliding contacts in order to ensure electrical contact in each rotational position.

Figur 6 zeigt die Befestigung des Sensors 160 am Gehäuseteil 141. FIG. 6 shows the attachment of the sensor 160 to the housing part 141.

Figur 7 zeigt ein Verfahren zum Betreiben des Vlieswicklers 1 zum Trennen eines Vlieses. FIG. 7 shows a method of operating the nonwoven winder 1 for separating a nonwoven fabric.

Nach dem Beginn in Schritt S1 wird in üblicher Weise zunächst die in Figur 1 dargestellte Wickelwelle 16 in der Wickelposition 5 in einem Schritt S2 bewickelt.After the start in step S1, the winding shaft 16 shown in FIG. 1 is wound in the winding position 5 in a customary manner, first in a step S2.

Dabei wird in einem nachfolgenden Schritt S3 geprüft, ob das Ende des Bewickelns ansteht. Diese Prüfung kann mittels eines Sensors geprüft werden, mittels dessen beispielsweise der Außendurchmesser und/oder das Gewicht der Wickelwelle 16 erfasst wird. Alternativ oder zusätzlich dazu kann auch die Länge des aufgewickelten Vlieses sensorisch beispielsweise mittels eines sensorischen Zählers sensorisch erfasst werden. Eine Kombination eines Inkrementalgebers für die Umdrehungen der Wickelwelle und eine sensorische Erfassung des jeweiligen Außendurchmessers der Wickelwelle wären eine geeignete Sensorlösung. Beide Schritte S2 und S3 können auch in ein und demselben Schritt ausgeführt werden.In this case, it is checked in a subsequent step S3, whether the end of the winding is pending. This test can be checked by means of a sensor, by means of which, for example, the outer diameter and / or the weight of the winding shaft 16 is detected. Alternatively or additionally Also, the length of the wound web are sensory detected, for example by means of a sensory counter sensor. A combination of an incremental encoder for the revolutions of the winding shaft and a sensory detection of the respective outer diameter of the winding shaft would be a suitable sensor solution. Both steps S2 and S3 can also be executed in one and the same step.

Ist dies nicht der Fall (Nein-Zweig nach Schritt S3), wird zu Schritt S2 zurückgekehrt. Andernfalls (Ja-Zweig nach Schritt S3) werden die nächste Wickelwelle und der Gehäuseabschnitt 140 in einem nachfolgenden Schritt S4 vorbereitet. Schritt S4 beinhaltet vorzugsweise das Andrehen der sich in Warteposition 3 befindlichen Wickelwelle 15 mittels des Andrehabschnitts 12 und das Transportieren von ihr in die Anwickelposition 4 mittels des Verriegelungs- und Bewegungsabschnitts 10. Der Gehäuseabschnitt 140 wird vermittels des Antriebsabschnitts 120 in die in Figur 1 dargestellte Position oder etwas weiter im Uhrzeigersinn gedreht. Exemplarisch stellt die in Figur 1 dargestellte Position des Gehäuseabschnitts 140 dessen Trennposition dar.If this is not the case (no branch after step S3), the system returns to step S2. Otherwise (Yes branch after step S3), the next winding shaft and the housing portion 140 are prepared in a subsequent step S4. Step S4 preferably involves turning the winding shaft 15 located in the waiting position 3 by means of the clamping section 12 and transporting it to the winding position 4 by means of the locking and moving section 10. The housing section 140 is inserted into the in FIG. 1 shown position or slightly further rotated clockwise. As an example, the in FIG. 1 shown position of the housing portion 140 whose separation position is.

In einem nachfolgenden Schritt S5 wird geprüft, ob die Trennposition erreicht ist. Wenn nicht (Nein-Zweig nach Schritt S5, wird zu Schritt S4 gesprungen.In a subsequent step S5, it is checked whether the separation position has been reached. If not (no branch after step S5), jump to step S4.

Andernfalls (Ja-Zweig nach Schritt S5) wird der Schneidabschnitt 106 in einem nachfolgenden Schritt S6 in einen Zustand bewegt, in dem er das Vlies trennen kann; bei der gezeigten Ausführungsform also mittels Einfahrens des Kolbens 103 des Pneumatikzylinders 102 herausgeklappt.Otherwise (Yes branch after step S5), the cutting portion 106 is moved to a state in which it can separate the nonwoven in a subsequent step S6; in the embodiment shown so folded out by retraction of the piston 103 of the pneumatic cylinder 102.

Zugleich (durchgezogene Linie) oder nach Schritt S6 (Strichpunktlinie) wird das mittels des Schneidabschnitts 106 getrennte, frei gewordene Teilvlies in einem Schritt S7 in Richtung der sich in Anwickelposition 4 befindlichen Wickelwelle hier mittels Blasluft aus den Blaselementen 152 befördert.At the same time (solid line) or after step S6 (dotted line) is the separated by means of the cutting portion 106, freed part fleece in a step S7 in the direction of the winding shaft 4 located in Anwickelposition 4 transported here by means of blown air from the blowing elements 152.

Danach (durchgezogene Linie) oder zugleich (Strichpunktlinie) kann der Schneidabschnitt 106 in einem Schritt S8 wieder eingeklappt werden. Im Zuge dessen wird der Gehäuseabschnitt 140 vorzugsweise im Uhrzeigersinn in Figur 1 weitergedreht, sodass der Gehäuseabschnitt 140 kein Vlies mehr berühren kann. Zudem werden die Wickelwelle 16 spätestens jetzt mittels des Wickel- und Ausschubabschnitts 11 in die Ausschubposition 6 bewegt, und die angewickelte Wickelwelle mittels des Verriegelungs- und Bewegungsabschnitts 10 in die Wickelposition 5 bewegt und vom Wickel- und Ausschubabschnitt 11 übernommen. Der Verriegelungs- und Bewegungsabschnitt 10 bewegt sich zurück, um die nächste zu bewickelnde Wickelwelle übernehmen zu können.Thereafter (solid line) or at the same time (dotted line), the cutting portion 106 can be folded back in a step S8. In the course of which the housing portion 140 is preferably in a clockwise direction in FIG FIG. 1 further rotated so that the housing portion 140 can no longer touch a fleece. In addition, the winding shaft 16 are now moved by means of the winding and Ausschubabschnitts 11 in the Ausschubposition 6, and the wound winding shaft by means of the locking and moving portion 10 moves to the winding position 5 and taken over by the winding and Ausschubabschnitt 11. The locking and moving portion 10 moves back to take over the next winding shaft to be wound can.

Schließlich wird vorzugsweise zu Schritt S2 zurückgesprungen, oder das Verfahren wird einfach beendet.Finally, it is preferable to return to step S2, or the process is simply terminated.

Die Erfindung ist nicht auf die vorbeschriebenen Ausführungen beschränkt.The invention is not limited to the above-described embodiments.

Das Übertragungselement 108 und die Welle 105 können frei rotierbar zueinander angeordnet sein.The transmission element 108 and the shaft 105 can be freely rotatable relative to one another.

Anstelle des Herausklappens des Schneidabschnitts 106 mittels Rotierens des Übertragungselements 108 kann auch ein Herausfahren beispielsweise mittels eines Schneckengetriebes und eines Elektromotors vorgesehen sein.Instead of folding out the cutting section 106 by means of rotating the transmission element 108, it is also possible to provide for moving out, for example, by means of a worm gear and an electric motor.

Das eingangs genannte Festlager ist vorzugsweise mittels einer der Gestellwände 7 gebildet, und das zugehörige Drehlager mittels der zugehörigen Riemenscheibe 126.The aforementioned bearing is preferably formed by means of one of the frame walls 7, and the associated pivot bearing means of the associated pulley 126th

Der vorbeschriebene Riementrieb kann durch einen Kettentrieb oder jedwede andere Getriebeart ersetzt sein. Die Motor-Getriebe-Einheit 121, 122 kann an beiden Gestellwänden 7, 7 vorgesehen sein.The above-described belt drive may be replaced by a chain drive or any other type of transmission. The motor-gear unit 121, 122 may be provided on both frame walls 7, 7.

Im Fall eines pneumatischen Sensors 160 ist dieser mit einem in Bezug auf den Vlieswickler 1 ortsfest angeordneten Wandler gekoppelt, der das pneumatische Sensorsignal in ein elektrisches Signal umwandelt und an die vorgenannte Steuerschaltung ausgibt.In the case of a pneumatic sensor 160, this is coupled to a stationary with respect to the nonwoven winder 1 transducer, which converts the pneumatic sensor signal into an electrical signal and outputs to the aforementioned control circuit.

Der Sensor 160 kann auch mehrfach vorgesehen sein, was die Ausfallgefahr verringert.The sensor 160 can also be provided several times, which reduces the risk of failure.

Im Ergebnis schafft die Erfindung eine sehr preiswerte und sichere Trennvorrichtung zur Integration in einen Vlieswickler und ein einfaches Betriebsverfahren dafür.As a result, the invention provides a very inexpensive and safe separator for integration into a nonwoven winder and a simple method of operation therefor.
