Description
Die Erfindung bezieht sich auf eine Tambourablagestation mit einem Wickeltambour, der einen mit einem Wickel einer Materialbahn bewickelten Wickelkern umfasst, und mit einem einseitig befestigten und feststehenden Wickeldorn.The invention relates to a Tambourablagestation with a winding drum comprising a wound with a winding of a web winding core, and with a unilaterally fixed and fixed winding mandrel.
Bei der Herstellung einer Materialbahn, insbesondere einer Papier-, Karton-, Tissue- oder einer anderen Faserstoffbahn, wird üblicherweise eine endlose Bahn erzeugt und auf Wickeltamboure bis zum Erreichen eines gewünschten Durchmessers aufgerollt. Die aufgewickelte Materialbahn wird zur nachfolgenden Behandlung in einer Verarbeitungsmaschine, beispielsweise in einer Rollenschneidmaschine, einer Umrollmaschine, einem Kalander oder einer Streichmaschine, weitertransportiert und in einer entsprechenden Abrollvorrichtung wieder abgespult Sowohl beim Auf- als auch beim Abwickeln dieser Wickeltamboure fallen bestimmte Mengen an Ausschussmaterial an, dessen Behandlung und Rückführung in den Produktionsprozess oft zu großen Behinderungen für den Produktionsprozess führt.In the production of a material web, in particular a paper, board, tissue or another fibrous web, an endless web is usually produced and rolled up on winding reels until a desired diameter is reached. The wound-up material web is transported further for subsequent treatment in a processing machine, for example in a slitter-winder, a rerolling machine, a calender or a coater, and unwound again in a corresponding unwinding device. Both when winding and unwinding these winding tubes, certain amounts of reject material are produced. its treatment and return to the production process often leads to major obstacles to the production process.
Bekannt sind Abrollvorrichtungen mit einer Bremse, bei denen der Ausschuss bahnbreit in einen Auflöser geleitet wird. Auch das Abrollen von Ausschuss in einer speziellen Abrollvorrichtung der Verarbeitungsmaschine ist bekannt. Ebenso gehört das Abschwarten von Ausschusslagen oder von Lagenpaketen von Hand in einer Abrollvorrichtung einer Verarbeitungsmaschine zum Stand der Technik. Auch in Volltambourablagestationen wird manuell eingegriffen, um Lagenpakete abzuschwarten.Abrolling devices are known with a brake in which the Committee is passed web width in a resolver. The unrolling of broke in a special unwinding device of the processing machine is also known.

Die Nachteile des Standes der Technik bestehen darin, dass alle genannten Verfahren einen permanenten Personaleinsatz zur Durchführung und Überwachung bedingen. Die Ausschussbehandlung innerhalb des Transportsystems zwischen einem Maschinenroller und der Verarbeitungsmaschine kann zu Störungen und Verzögerungen im Materialfluss zur Herstellung der fertig veredelten Materialbahn führen.The disadvantages of the prior art are that all said methods require a permanent staff deployment for implementation and monitoring. The scrap treatment within the transport system between a machine roller and the processing machine can lead to disturbances and delays in the material flow for the production of the finished finished material web.
Die manuelle Ausschussbehandlung ist oftmals mit besonderen Gefahren für das durchführende Personal verbunden und macht beispielsweise den Aufenthalt am Abwurfschacht erforderlich. Das Personal kann auch durch herabfallende Bahnschwarten gefährdet werden. Ebenso ist allein der Zug, den die Materialbahn ausübt, eine Gefahr für das Personal, das sich in der Nähe der Materialbahn aufhalten muss.The manual reject treatment is often associated with special risks for the personnel performing and makes, for example, the stay at the discharge chute required. The staff can also be endangered by falling ropes. Likewise, only the train, which carries the web, a danger to the staff who must stay near the web.
Es ist die Aufgabe der Erfindung, eine Vorrichtung zu schaffen, die die Nachteile des Standes der Technik überwindet und eine einfache Möglichkeit zur Beseitigung von Ausschuss einer Materialbahn schafft.It is the object of the invention to provide a device which overcomes the disadvantages of the prior art and provides an easy way to eliminate scrap of a web.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Wickeltambour durch eine Antriebseinrichtung antreibbar ist, dass der Wickeldorn im Abrollbereich des Wickeltambours unter einem Winkel zur Längsachse des Wickeltambours angeordnet ist, wobei der Winkel einen Wert im Bereich von größer 0 und kleiner 90°, vorzugsweise im Bereich von 5 und 45°, aufweist, dass auf den Wickeldorn die Materialbahn von dem Wickeltambour mittels einer Aufwickeleinrichtung wendelförmig aufwickelbar ist, und dass die wendelförmig gewickelte und von dem Wickeldorn herabgleitende Materialbahn einer Zerkleinerungseinheit, insbesondere zwei mit einander zusammenwirkenden Messern oder mit Zähnen oder Stacheln versehenen Walzen, zuführbar ist. Die Materialbahn wird somit um den Wickeldorn nach Art eines eine Zigarre umgebenden äußeren Tabakblattes gewickelt.According to the invention, this object is achieved in that the winding mandrel is drivable by a drive means that the winding mandrel is arranged in the rolling region of the winding drum at an angle to the longitudinal axis of the winding drum, wherein the angle has a value in the range of greater than 0 and less than 90 °, preferably in the Range of 5 and 45 °, that on the winding mandrel, the material web of the winding drum by means of a winding device is wound helically, and that the helically wound and sliding down from the winding mandrel web of a crushing unit, in particular two interacting knives or with teeth or spikes provided rolls, can be fed. The material web is thus wound around the mandrel in the manner of a surrounding a cigar outer tobacco leaf.
Bei der erfindungsgemäßen Tambourablagestation ist ein Eingreifen von Personal nicht erforderlich; Tambourablagestation umfasst eine Dreheinrichtung zum Antreiben des Wickeltambours, beispielsweise einen Getriebemotor mit einem auf die Mantelfläche des auf dem Wickeltambour aufgebrachten Wickels angreifenden Reibrad. Alternativ hat der Wickeltambour einen Kernantrieb, beispielsweise mit einer in der Antriebswelle eingebrachten verschiebbaren Zahnkupplung oder dergleichen. Die Tambourablagestation wird entweder von einem Tambourtransportsystem oder durch einen Tambourkran beschickt.In the tambourine storage station according to the invention, intervention by personnel is not required; Tambourablagestation comprises a rotating device for driving the winding drum, for example, a geared motor with an acting on the outer surface of the wound on the winding drum winding friction wheel. Alternatively, the winding drum has a core drive, for example, with a slidable toothed coupling introduced in the drive shaft or the like. The drum storage station is either fed by a spool transport system or by a tambour crane.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen.Advantageous developments emerge from the subclaims, the description and the drawings.
Die auf dem Wickeltambour aufgewickelte Materialbahn wird dadurch entsorgt, dass ein vorzugsweise mit einer reibungsarmen Oberfläche ausgestatteter Wickeldorn, eine Antriebseinrichtung zum wendelförmigen Umwickeln des Wickeldorns mit der Materialbahn und ein asymmetrisch geschlitzter Führungskanal oder eine Führungswanne eingesetzt werden, die die wendelförmig aufgewickelte Materialbahn von außen umgeben und leiten.The wound on the reel spool web is disposed of by a preferably provided with a low-friction surface mandrel, a drive means for helically wrapping the winding mandrel with the material web and an asymmetrically slotted guide channel or a guide trough are used, which surrounds the helically wound material web from the outside and conduct.
Der Bahnanfang wird vorzugsweise von einem Antriebsriemen, der den Wickeldom unter einem möglichst großen Winkel umschlingt, unter Zuhilfenahme einer Einführhilfe, beispielsweise eines Vakuumbandes erfasst. Die Einführhilfe besteht beispielsweise aus einer Antriebsrolle mit einer Antriebseinrichtung und einer Umlenkrolle mit einer entsprechenden Lagerung. Die Antriebseinrichtung kann zum Beispiel ein Elektromotor oder ein fluidbetriebener Motor sein. Zwischen den beiden Rollen ist ein luftdurchlässiges und umlaufendes Endlosband aus einem flexiblen Material, zum Beispiel eine gelochte Kunststoffbahn, ein Geflecht oder dergleichen, geführt. An der Antriebsrolle greift eine Belastungseinrichtung, zum Beispiel ein fluiddruckbeaufschlagter Aktuator, zur Herstellung des Kontaktes zwischen dem Endlosband und der Materialbahn auf dem Wickelkern an. Innerhalb des umlaufenden Endlosbands ist zur Seite der Materialbahn hin gerichtet ein Vakuumkanal angeordnet, welcher zum Bandtrum auf der Seite der ablaufenden Materialbahn offen ist. Dieser Vakuumkanal ist mit einer Einrichtung zur zeugung eines Unterdrucks versehen, welcher auf der offenen Seite des Vakuumkanals durch das umlaufende Endlosband wirkt und für das Ablösen des Bahnanfangs vom Wickelkern und dessen zuverlässigen Transport zu einer Einlaufstelle einer Ausschussbehandlungseinrichtung.The web start is preferably detected by a drive belt, which wraps around the winding dome at the largest possible angle, with the aid of an insertion aid, for example a vacuum belt. The insertion aid consists for example of a drive roller with a drive device and a deflection roller with a corresponding storage. The drive device may be, for example, an electric motor or a fluid-operated motor. Between the two rollers, an air-permeable and circulating endless belt made of a flexible material, for example a perforated plastic web, a mesh or the like, out. On the drive roller engages a loading device, for example, a fluiddruckbeaufschlagter actuator, for producing the contact between the endless belt and the material web on the winding core. Within the revolving endless belt is directed to the side of the web directed toward a vacuum channel, which is the belt strand on the side of the expiring Material web is open. This vacuum channel is provided with a device for generating a negative pressure, which acts on the open side of the vacuum channel through the circulating endless belt and for the detachment of the web start from the winding core and its reliable transport to an inlet point of a waste treatment device.
In einer bevorzugten Ausgestaltung ist die Riemenführung gegenüber der Materialbahn und/oder dem Wickeldorn verschränkt angeordnet. Alternativ ist eine die Materialbahn an den Wickeldorn anpressende Antriebsrolle vorgesehen. Die Bahnspannung wird dabei durch eine auf den Wickeltambour einwirkende Bremse annähernd konstant gehalten.In a preferred embodiment, the belt guide is arranged opposite to the material web and / or the mandrel entangled. Alternatively, a web of material to the winding mandrel pressing drive roller is provided. The web tension is kept approximately constant by a brake acting on the winding drum.
In einer weiteren bevorzugten Alternative oder zusätzlich zu einem Antrieb durch einen Antriebsriemen oder eine Antriebsrolle in Form eines Reibrades wird die Materialbahn durch einen Druckluftantrieb, insbesondere durch einen Zyklon, auf den Wickeldorn aufwickelt.In a further preferred alternative or in addition to a drive by a drive belt or a drive roller in the form of a friction wheel, the material web is wound on the winding mandrel by a pneumatic drive, in particular by a cyclone.
Durch die Anordnung der Wickelachsen des Wickeltambours und des Wickeldorns unter einem spitzen oder stumpfen Winkel und auch durch die Verschränkung der Riemenführung wird ein Vorschub der Materialbahn erzeugt, der die entstehende wendelförmige Materialbahnhülse entlang der Achse des Wickeldorns kontinuierlich in Richtung eines immer größeren Achsabstandes zwischen dem Wickeltambour und dem Wickeldorn bewegt. Zur Unterstützung dieser Bewegung ist vorzugsweise vorgesehen, dass der Wickeldorn von einem, insbesondere asymmetrisch mit Schlitzen ausgestatteten, Führungskanal zur Führung der wendelförmig aufgewickelten Materialbahn umgeben ist oder dass eine, insbesondere asymmetrisch mit Schlitzen ausgestattete, Führungswanne auf der Unterseite des Wickeldorns angeordnet ist. Der Führungskanal ist entweder auf der Innenseite der von der Materialbahn gebildeten Hülse oder auf der Außenseite der Materialbahnhülse angeordnet.By arranging the winding axes of the winding cylinder and the winding mandrel at an acute or obtuse angle and also by the entanglement of the belt guide a feed of the material web is generated, the resulting helical material web sleeve along the axis of the winding mandrel continuously in the direction of an ever greater center distance between the winding drum and the winding mandrel moves. To support this movement is preferably provided that the winding mandrel is surrounded by a, in particular asymmetrically equipped with slots, guide channel for guiding the helically wound material web or that, in particular asymmetrically equipped with slots, guide trough is arranged on the underside of the winding mandrel. The guide channel is arranged either on the inside of the sleeve formed by the material web or on the outside of the material web sleeve.
Es erweist sich als vorteilhaft, wenn der Führungskanal bzw. die Führungswanne einen kreis- oder schneckenförmigen Querschnitt hat.It proves to be advantageous if the guide channel or the guide trough has a circular or helical cross-section.
Die Mantelfläche des Wickelkerns ist durch einen geringen Reibungskoeffizienten gekennzeichnet, um das Gleiten der Innenseite der ihn umgebenden Materialbahnhülse zu begünstigen. Die Länge des Wickeldorns erstreckt sich im wesentlichen von seinem einseitigen Befestigungsbereich außerhalb der Wickelvorrichtung, das heißt außerhalb des Bereichs, in dem die Materialbahn wendelförmig aufgenommen wird, bis mindestens über den Umschlingungsbereich durch den Treib- oder Antriebsriemen bzw. den Angriffsbereich der Antriebsrolle. Eine weitere Maßnahme, um die Reibung zu reduzieren, besteht darin, dass der Wickeldorn einen inneren Kanal aufweist, aus dem über mantelseitige Bohrungen Druckluft gegen die wickeldornseitige Innenfläche der Materialbahn gepresst wird.The lateral surface of the winding core is characterized by a low coefficient of friction in order to promote the sliding of the inside of the material web sleeve surrounding it. The length of the winding mandrel extends substantially from its one-sided attachment region outside the winding device, that is outside of the range in which the material web is received helically, at least over the wrap around by the drive or drive belt or the attack region of the drive roller. Another measure to reduce the friction is that the winding mandrel has an inner channel, from the shell-side holes compressed air against the winding mandrel-side inner surface of the material web is pressed.
Von der Zerkleinerungseinheit oder unmittelbar vom freien Ende des Wickeldorns gleitet die Materialbahn auf ein Förderband, in einen zu einem Auflöser führenden Schacht oder wird einer Absaugeinrichtung zugeführt.From the crushing unit or directly from the free end of the winding mandrel, the material web slides on a conveyor belt, in a leading to a dissolver shaft or is fed to a suction device.
Die Tambourablagestation ist entweder separat angeordnet, oder sie ist in ein Magazin für Voll-, Ausschuss- oder Resttamboure integriert; sie kann jedoch auch in ein übergreifendes Transportsystem für bewickelte oder leere Tamboure eingebunden sein. Durch die kompakte Bauform und den seitlichen Materialbahnaustrag kann auch der Einbau in ein Tambourmagazin an einem Maschinenroller realisiert werden.The drum storage station is either arranged separately or it is integrated in a magazine for full, reject or residual reboots; However, it can also be integrated into an overall transport system for wound or empty reels. Due to the compact design and the lateral material web discharge also the installation in a spool magazine can be realized on a machine scooter.
Insgesamt bestehen die Vorteile der Lösung darin, dass ein verhältnismäßig geringer Einbauraum erforderlich ist, dass nur ein geringer Bedarf für einen manuellen Eingriff besteht und dass der Aufstellungsort der Abschwarteinrichtung nicht unmittelbar an die Aufstellung des Auflösers gebunden ist. Die Bahnablaufgeschwindigkeit lässt sich bedarfsorientiert steuern. Aufgrund der kontinuierlichen Abarbeitung der vorhandenen Ausschussmenge besteht nur eine geringe Anforderung an die maximale Auflöserkapazität. Die Erfindung ist unabhängig vom jeweiligen Wickeldurchmesser anwendbar und lässt sich mit Tambourtransportsystemen problemlos kombinieren.Overall, the advantages of the solution is that a relatively small installation space is required, that there is little need for manual intervention and that the site of the Abschwarteinrichtung is not directly tied to the installation of the resolver. The web run speed can be controlled according to demand. Due to the continuous processing of the existing waste quantity, there is only a small requirement for the maximum dissolving capacity. The invention is applicable regardless of the respective winding diameter and can be easily combined with Tambourtransportsystemen.
Nachfolgend wird die Erfindung in Ausführungsbeispielen näher erläutert.The invention will be explained in more detail in exemplary embodiments.
