Verfahren und Vorrichtung zum Einführen einer Materialbahn in eine VerarbeitungsmaschineMethod and device for introducing a material web into a processing machine
Technisches GebietTechnical field
Die Erfindung betrifft ein Verfahren zum Einführen einer Materialbahn in eine Verarbeitungsmaschine, insbesondere in eine Maschine zum Aufwickeln von Papier- oder Kartonbahnen zu Wickelrollen, gemäß dem Oberbegriff des Patentanspruchs 1 und eine Vorrichtung zur Durchführung des Verfahrens. .The invention relates to a method for introducing a material web into a processing machine, in particular into a machine for winding paper or cardboard webs into winding rolls, according to the preamble of claim 1 and a device for carrying out the method. .
Zum Einführen einer Materialbahn in eine Verarbeitungsmaschine, insbesondere in eine Maschine zum Aufwickeln von Papier- oder Kartonbahnen, sind verschiedene Systeme bekannt, die einen erheblichen Arbeits- und■Konstruktionsaufwand erfordern. Insbesondere das Heranführen eines neuen Bahnanfanges an die Stütz- oder Tragwalze einer Wickelmaschine mit einer teilweise Unterflur verlaufenden Bahnführungsstrecke gestaltet sich schwierig, da die Bahnführungsstrecke streckenweise nicht zugänglich ist. In dem unzugänglichen Bereich müssen aufwendige Transportbänder und Bänderschwingen zur Führung des Materialbahnanfangs angeordnet werden, darüber hinaus ist es erforderlich, daß eine Bedienungsperson an den kritischen Stellen manuell nachhilft. Stand der TechnikVarious systems are known for introducing a material web into a processing machine, in particular into a machine for winding paper or cardboard webs, which require a considerable amount of work and construction. In particular, guiding a new start of the web to the support or support roller of a winding machine with a web guiding route running partially under the floor is difficult because the web guiding route is not accessible in some areas. In the inaccessible area, complex conveyor belts and swing arms must be arranged to guide the start of the material web. In addition, it is necessary for an operator to manually assist at the critical points. State of the art
Um den Einzug einer neuen Materialbahn zu automatisieren ist aus der DE-OS 37 10 039 ein gattungsge äßes Verfahren bekannt, bei dem längs der Materialbahnführung ein Aufführseil über Umlenkrollen geführt ist, an dem der Materialbahnanfang anschließbar ist. Diese Vorrichtung ist konstruktiv aufwendig, da zusätzliche Umlenkrollen für das stationär angeordnete Aufführseil und Auswürfmittel für das Aufführseil erforderlich sind, die es nach dem Bahneinzug in eine nicht störende Position bringen.In order to automate the insertion of a new web of material, a generic method is known from DE-OS 37 10 039, in which a guide rope is guided along the material web guide over pulleys, to which the material web start can be connected. This device is structurally complex, since additional deflection rollers for the stationary arranged rope and ejection means for the rope are required, which bring it into a non-disturbing position after the web is drawn.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren zu schaffen, das bei geringem konstruktiven Aufwand eine sichere Einführung einer neuen Materialbahn ermöglicht. Eine weitere Aufgabe liegt in der Bereitstellung einer Vorrichtung zur Durchführung eines erfindungsgemäßen Verfahrens.The invention has for its object to provide a generic method that enables safe introduction of a new material web with little design effort. Another object is to provide a device for carrying out a method according to the invention.
Die erste Aufgabe wird mit den Maßnahmen des Patentanspruchs 1 gelöst. Es hat sich gezeigt, daß sich ein Band mittels einer laminaren Druckluftströmung entlang eines Führungselementes durch eine mit Kurven versehene Strecke transportieren läßt. Es werden nur ein schmales Bahnführungselement, vorzugsweise eine Rinne, und in regelmäßigen Abständen angeordnete Flach- strahldüsen benötigt. Das Führungselement kann an den die Bahnführung kreuzenden Stellen Unterbrechungen aufweisen, so daß der Bahnverlauf nicht beeinträchtigt wird. Zum Einführen einer Materialbahn wird zunächst das elastische, zugfeste Band mittels Druckluft in die Bahnführungsstrecke eingeführt, anschließend wird es mit der daran befestigten Materialbahn durch die Bahnführungsstrecke gezogen und so wieder aus dieser entfernt.The first task is solved with the measures of claim 1. It has been shown that a belt can be transported by means of a laminar flow of compressed air along a guide element through a route provided with curves. Only a narrow web guiding element, preferably a channel, and flat jet nozzles arranged at regular intervals are required. The guide element can have interruptions at the points crossing the web guide so that the path of the web is not impaired. To insert a material web, the elastic, tensile band is first introduced into the web guide section by means of compressed air, then it is pulled with the material web attached to it through the web guide section and thus removed again from the latter.
Die zweite Aufgabe wird mit den Merkmalen des Anspruchs 2 gelöst. Die Unteransprüche enthalten bevorzugte Ausgestaltungen einer Vorrichtung nach Anspruch 2:The second object is achieved with the features of claim 2. The subclaims contain preferred configurations of a device according to claim 2:
Während das Merkmal des Anspruchs 3 einen sicheren Transport des Bandes durch die Bahnführungsstrecke gewährleistet, ermöglicht das Merkmal des Anspruchs 4 eine Verkürzung der für die Einführung benötigten Zeit, da die neue Vorratsrolle bereits vorher vorbereitet werden kann und während der Stillstandszeit nur noch das Band an das am Anfang der Materialbahn befestigte Verbindungsteil angekuppelt werden muß.While the feature of claim 3 ensures a safe transport of the tape through the web guide, the feature of claim 4 enables a reduction in the time required for the introduction, since the new supply roll can be prepared beforehand and only the tape to the during the downtime at the beginning of the material web attached connecting part must be coupled.
Kurze Beschreibung der ZeichnungBrief description of the drawing
Die Zeichnung dient zur Erläuterung der Erfindung anhand eines vereinfacht dargestellten Ausführungsbeispiels.The drawing serves to explain the invention with reference to an embodiment shown in simplified form.
Fig. 1 zeigt einen Längsschnitt in Bahnlaufrichtung durch eine Wiσkelmaschine mit einer Bahneinführungseinrichtung nach der Erfindung,1 shows a longitudinal section in the web running direction through a winding machine with a web insertion device according to the invention,
Fig. 2 zeigt einen vergrößerten Ausschnitt der. Führungsrinne.Fig. 2 shows an enlarged section of the . Guide trough.
Weg zur Ausführung der ErfindungWay of carrying out the invention
Die in Fig. 1 schematisch gezeigte Wickelmaschine ist eine sogenannte Stützwalzen-Rollmaschine, bei der die Materialbahn 1, eine bis zu 8 m breite Papier- oder Kartonbahn, von einer Abrollung 2 ankommend längs in Einzelbahnen aufgeteilt wird, die zu Wickelrollen 3 aufgewickelt werden. Die Wickelrollen 3 liegen während des Aufwickelns wechselweise beidseits der Scheitellinie angeordnet auf einer angetriebenen Stützwalze 4. Die Bahn 1 wird an die Stützwalze 4 von unten herangeführt, so daß diese teilweis umschlungen ist. Mit Abstand unterhalb der Stützwalze 4 befindet sich eine Längsschneideeinrichtung 5, die die Bahn 1 in Einzelbahnen aufteilt. Bei einer Zuführung der Bahn 1 von unten an eine Trag- oder Stützwalze ist es erforderlich, die Bahn 1 zumindest teilweise Unterflur zu führen, damit zwischen der Abrollung 2 und der Wickel aschine ein Freiraum zum Entladen der vollen Wickelrollen 3 bleibt. Zur Bahnführung dienen Leitrollen 6 bis 10, die die Bahn 1 zunächst nach unten in den Unterflurbereich ablenken, dann in etw horizontal bis in den Bereich unterhalb der Stützwalze 4. Dort wird sie von einer Leitrolle 11 in etwa senkrecht nach oben umgelenkt. Im Anschluß an die senkrechte Strecke, an der die Längsschneideeinrichtung 5 angeordnet ist, lenkt eine Umlenkrolle 12 die Bahn in etwa tangential an die Stützwalze 4.The winding machine shown schematically in FIG. 1 is a so-called back-up roll rolling machine, in which the material web 1, an up to 8 m wide paper or cardboard web, arriving from a roll 2 is divided lengthways into individual webs which are wound into winding rolls 3. The winding rolls 3 are alternately arranged on both sides of the apex line on a driven support roller 4 during the winding. The web 1 is brought up to the support roller 4 from below, so that it is partially wrapped around it. At a distance below the support roller 4 is a longitudinal cutting device 5, which divides the web 1 into individual webs. When the web 1 is fed from below to a support or support roller, it is necessary to guide the web 1 at least partially underfloor, so that there is a free space between the unwind 2 and the winding machine for unloading the full winding rolls 3. Guide rollers 6 to 10 serve to guide the web, which first deflect the web 1 downwards into the underfloor region, then horizontally into approximately the region below the support roller 4. There it is deflected approximately vertically upwards by a guide roller 11. Following the vertical line on which the longitudinal cutting device 5 is arranged, a deflection roller 12 guides the web approximately tangentially to the support roller 4.
Zum Einführen einer neuen Bahn 1 in die Wickelmaschine, z. B. nac einem Vorratsrollenwechsel in der Abrollung 2 oder nach einem Bahnabriß, dienen die nachfolgend beschriebenen Elemente.Etwa mittig zur Arbeitsbreite ist entlang der Bahnführungs- strecke mi geringem Abstand von dieser ein Führungselement, vorzugsweise.ein Führungsrinne 13, für ein Schleppband 15 angeordnet. Die Führungsrinne 13 weist einen U-förmigen Querschnitt auf und ist zur Bahnführungsebene hin offen. Ihre Breite beträgt zwischen 50 mm und 100 mm, die Höhe der Schenkel ca. 20 mm. Die Rinne 13 befindet sich im in etwa waagerecht verlaufenden Teil der Bahnführungsstrecke unterhalb von dieser und reicht bis zur letzten Umlenkrolle 11 vor der Längsschneideeinrichtung 5. Zur Vermeidung von störenden Kreuzungen mit der Bahnführungsstrecke ist die Führungsrinne 13 im Bereich der nach unten ablenkenden Leitrolle 8 unterbrochen. Dort befindet sich oberhalb der Leitrolle 8 ein kreisbogenförmig gekrümmtes Teil 13.1 der Führungsrinne 13, das nach unten geöffnet ist, wobei für die kreuzende Bahn 1 Freiräume zur Rinne 13 freigelassen wurden.To insert a new web 1 into the winding machine, e.g. For example, after changing the supply roll in the unwind 2 or after a web break, the elements described below are used. Approximately in the middle of the working width, a guide element, preferably a guide channel 13, is arranged along the web guide path at a short distance from it. The guide trough 13 has a U-shaped cross section and is open towards the web guide plane. Their width is between 50 mm and 100 mm, the height of the legs about 20 mm. The trough 13 is located in the approximately horizontal part of the web guide section below it and extends to the last deflecting roller 11 in front of the longitudinal cutting device 5. There is above the guide roller 8 a part 13.1 of the guide trough 13 which is curved in the shape of an arc of a circle and which is open at the bottom, wherein 1 spaces for the trough 13 have been left free for the crossing path.
Die Führungsrinne 13 ist in regelmäßigen Abständen, etwa alle 0,5-1 m, unterbrochen. An den Unterbrechungen sind jeweils Flachstrahldüsen 14 angeordnet, die in Bahnlaufrichtung laminar strömende Druckluft in die Rinne 13 einblasen, wobei der Abstand der Ausblasöffnungen vom Boden der Rinne 13 weniger als 10 mm, vorzugsweise 0,5 mm - 1 mm, beträgt. Der Aufbau derartiger Flachstrahldüsen ist in der DE-PS 24 13 614 beschrieben. Auf diese Weise wird die gesamte Rinne 13 von einer zu ihrem Boden in etwa parallelen laminaren Druck¬ luftströmung durchflutet.The guide trough 13 is interrupted at regular intervals, approximately every 0.5-1 m. At the interruptions, flat jet nozzles 14 are arranged in each case, which blow compressed air flowing in the web running direction into the channel 13, the distance of the blow-out openings from the bottom of the channel 13 is less than 10 mm, preferably 0.5 mm - 1 mm. The structure of such flat jet nozzles is described in DE-PS 24 13 614. In this way, the entire channel 13 is flooded by a laminar compressed air flow which is approximately parallel to its base.
Im senkrechten Bereich zwischen den Leitrollen 11 und 12 ist ein heb- und senkbares Rinnenstück 13.2 angeordnet, das zwischen den auseinandergefahrenen Messern der Längsschneide- einrichtung 5 bis an die obere Leitrolle 12 angehoben und bis unterhalb der unteren Leitrolle 11 abgesenkt werden kann. Im Bereich der Leitrolle 12 schließt sich ein entsprechend gekrümmtes Führungsrinnenteil 13.3 an, mit Abstand von diesem - da an dieser Stelle die Bahn 1 die Führungsrinne 13 wiederum kreuzt - folgt ein Führungsrinnenteil 13.4, das in etwa tangential an die Stützwalze 4 heranreicht.In the vertical area between the guide rollers 11 and 12, a liftable and lowerable channel piece 13.2 is arranged, which can be raised between the extended knives of the slitter 5 to the upper guide roller 12 and lowered to below the lower guide roller 11. In the area of the guide roller 12 there is a correspondingly curved guide trough part 13.3, at a distance from this - since at this point the web 1 again crosses the guide trough 13 - there follows a guide trough part 13.4 which reaches the support roller 4 approximately tangentially.
Zum Einführen einer neuen Bahn 1 wird zunächst das Teil 13.2 der Führungsrinne hochgefahren, so daß die senkrechte Strecke zwischen den Leitwalzen 11 und 12 überbrückt ist. Anschließend wird die Druckluft eingeschaltet, so daß die gesamte Führungs¬ rinne 13 von der Abrollung 2 bis zur Stützwalze 4 von laminar strömender Druckluft, durchströmt ist. Danach wird ein leichtes, jedoch zugfestes Band 15 aus Papier, Textil oder Kunststoff von geringerer Breite als die Breite der Fuhrungs- rinne 13 bei der Abrollung 2 in die Führungsrinne 13 ein¬ geführt. Das Band 15 hat eine größere Länge als die Unterflur verlaufende Bandführungsstrecke und wird von der Druckluft durch die Rinne 13 transportiert bis sein Anfang an der Stützwalze 4 aus dem Unterflurbereich hervortritt. Am Ende des Bandes 15 ist eine Befestigungsmöglichkeit für ein Verbin¬ dungsteil zur Materialbahn angebracht. Als Verbindungsteil wird ein sogenannter "Drachen" verwendet, ein trapezförmiges Verbindungsteil, das an dem Anfang der neuen Bahn 1 lösbar, z.B. mit einem Klebestreifen, befestigt werden kann. Der Drachen wird an dem vorbereiteten Bahnanfang der neuen Vorratsrolle 2.1 befestigt. Nachdem sein Ende an dem Drachen angekuppelt wurde, wird das Band 15 im Bereich der Stütz¬ walze 4 manuell oder maschinell aus der Führungsrinne 13 herausgezogen und dabei aufgewickelt. Um die Zugbelastung möglichst gering zu halten, wird dabei der Antrieb der Abrollung 2 zugeschaltet. Das Band 15 zieht so den neuen Bahnanfang durch die Unterflur liegende Bahnführungsstrecke bis der neue Bahnanfang an der Stützwalze 4 aus dem Unterflurbereich heraustritt und von der als Saugwalze ausgebildeten Stützwalze 4 übernommen wird. Das Ende des Schleppbandes 15 wird danach vom Bahnanfang gelöst, das Rinnenteil 13.2 wird abgesenkt, und die Messer der Längs- schneideeinrichtuήg 5 werden an die Bahn 1 gefahren. Der Transport des neuen Bahnanfangs zu den Wickelstationen und die Befestigung der Einzelbahnen an den jeweiligen Wickelhülsen erfolgt dann in bekannter Weise mit der Stützwalze 4, an der der Bahnanfang festgesaugt ist.To introduce a new web 1, part 13.2 of the guide trough is first raised so that the vertical path between guide rollers 11 and 12 is bridged. Then the compressed air is switched on so that the entire guide channel 13 is flowed through by the unwind 2 to the support roller 4 of laminar flowing compressed air. Thereafter, a light, but tensile tape 15 made of paper, textile or plastic of a smaller width than the width of the guide trough 13 is introduced into the guide trough 13 during unwinding 2. The belt 15 has a greater length than the belt guide section running under the floor and is transported by the compressed air through the channel 13 until its beginning emerges from the underfloor area on the support roller 4. At the end of the band 15 there is an attachment option for a connecting part to the material web. A so-called "kite" is used as the connecting part, a trapezoidal connecting part which can be detachably fastened to the beginning of the new track 1, for example with an adhesive strip. The kite is attached to the prepared web start of the new supply roll 2.1. After its end has been coupled to the kite, the band 15 in the region of the support roller 4 is pulled out of the guide trough 13 manually or mechanically and wound up in the process. In order to keep the tensile load as low as possible, the drive of the unwind 2 is switched on. The belt 15 thus pulls the new web start through the underfloor web guide section until the new web start emerges from the underfloor area on the support roller 4 and is taken over by the support roller 4 designed as a suction roller. The end of the drag belt 15 is then released from the start of the web, the gutter part 13.2 is lowered, and the knives of the longitudinal cutting device 5 are moved to the web 1. The transport of the new start of the web to the winding stations and the attachment of the individual webs to the respective winding cores is then carried out in a known manner with the support roller 4, on which the beginning of the web is sucked up.
Das aufgewickelte Schleppband 15 wird zu der Abrollung 2 befördert und steht somit für die Einführung des nächsten Bahnanfangs bereit. Um die zur Einführung eines neuen Bahnanfangs benötigte Zeit möglichst kurz zu halten, kann das Band 15 bereits während des Entladens der vollen Wickel¬ rollen 3 durch die Führungsrinne 13. geführt werden. Bereits während die vorhergehende Vorratsrolle 2.1 noch abgewickelt wird, wird die neue Vorratsrolle außerhalb der Abrollstation vorbereitet, indem der Bahnanfang angespitzt und ein Drachen daran befestigt wird. Nach Einhängen der neuen Vorratsrolle in die Abrollung braucht daher nur noch das Ende des Schlepp¬ bandes 15 an dem Drachen befestigt zu werden.The wound drag belt 15 is conveyed to the unwind 2 and is thus ready for the introduction of the next start of the web. In order to keep the time required for the introduction of a new start of the web as short as possible, the belt 15 can already be guided through the guide trough 13 during the unloading of the full winding rolls 3. Already while the previous supply roll 2.1 is still being unwound, the new supply roll is prepared outside the unwinding station by sharpening the beginning of the web and attaching a kite to it. After the new supply roll has been hooked into the unwind, only the end of the drag belt 15 needs to be attached to the kite.
Das vorstehend beschriebene Ausführungsbeispiel zeigt das Einführen einer neuen Bahn durch den schwer zugänglichen Unterflurbereich einer Wickelmaschine. Das erfindungsgemäße Verfahren ist jedoch nicht auf diese Ausfuhrungsformen beschränkt. Es ist vorteilhaft an allen Verarbeitungsmaschinen - ~The exemplary embodiment described above shows the introduction of a new web through the underfloor area of a winding machine which is difficult to access. However, the method according to the invention is not restricted to these embodiments. It is beneficial on all processing machines - ~
für Materialbahnen einsetzbar, die eine schwer zugängliche, mit Kurven versehene Bahnzuführung aufweisen. Can be used for material webs that have a difficult to access, curved web feed.
