Description

Die Erfindung betrifft ein Verfahren zur automatischen Hülsenbestückung einer Wickelwelle an Rollenschneid- und Wickelmaschinen.The invention relates to a method for automatic tube insertion of a winding shaft on reel cutting and winding machines.

Rollenschneid- und Wickelmaschinen sind häufig mit zwei, zum Teil auch mit mehreren. Wickelwellen ausgerüstet, auf denen Wickelhülsen entsprechend der Breite der längs geschnittenen Bänder aufgebracht sind. Sehr oft sind diese Wickelhülsen auf friktionierenden Ringen befestigt, die von der etwas voreilenden Wickelwelle getragen werden. Die Voreilung dient dem Ausgleich von Längenund Durchmessertoleranzen der Wickelrollen. Die Befestigung der Hülsen auf den Friktionsringen geschieht üblicherweise, wie bei einem Freilauf, durch Klemmelemente, die über das Drehmoment aktiviert werden. Im Stillstand oder mit leichter Rückwärtsdrehung lassen sich die leeren Wickelhülsen axial leicht verschieben und an der richtigen Stelle, entsprechend der vorgegebenen Schnittbreiten der zu schneidenden Bänder, positionieren.Wrapping and winding machines are often with two, sometimes with several. Wickelwellen equipped, on which winding tubes are applied according to the width of the longitudinally cut bands. Very often, these cores are mounted on frictional rings, which are carried by the slightly leading winding shaft. The overfeed serves to compensate for length and diameter tolerances of the winding rolls. The attachment of the sleeves on the friction rings is usually done, as in a freewheel, by clamping elements that are activated by the torque. At a standstill or with slight backward rotation, the empty cores can be easily moved axially and positioned in the right place, according to the specified cutting widths of the tapes to be cut.

Es sind verschiedene Verfahren und Vorrichtungen zum Bestücken der Wickelwellen bekannt. Zwei unterschiedliche Wege zum Bestücken der Wickelwellen werden nachfolgend beschrieben. Vorausgesetzt wird für die nachstehende Beschreibung, dass beim Rollen- und Hülsenwechsel im Stillstand die Wickelwellen einseitig, meist an der Antriebsseite, fest gelagert sind und ein Stützlager am anderen Ende der Wickelwelle soweit von der Wickelwelle entfernt wird, dass ein fliegender Zustand der Wickelwelle entsteht, dies bezieht sich ebenso auf die erfindungsgemäße Vorrichtung und das Verfahren. Ein filegender Zustand wird beispielsweise dann erreicht, wenn ein Stützlager oder eine sonstige Lagerstelle von einem Ende der Wickelwelle entfernt wird, so dass das Ende der Wickelwelle frei in der Luft hängt. So können die fertig gewickelten Rollen abgeschoben und die leeren Hülsen aufgeschoben werden.Various methods and devices for equipping the winding shafts are known. Two different ways of equipping the winding shafts are described below. It is assumed for the following description that the roller shafts at standstill, the winding shafts are mounted on one side, usually on the drive side, and a support bearing at the other end of the winding shaft is far enough away from the winding shaft, that a flying state of the winding shaft is formed, this relates also to the device and the method according to the invention. A filing condition is achieved, for example, when a support bearing or other bearing is removed from one end of the winding shaft so that the end of the winding shaft hangs freely in the air. Thus, the finished wound rolls can be pushed off and the empty tubes are pushed.

In einem ersten Beispiel erfolgt das Abschieben der gewickelten Rollen von Hand auf ein stützendes Band oder auf eine an der Wickelwelle anliegenden Tragachse, von der die Wickelrollen später einzeln entnommen werden. Sind die Wickelrollen sehr schwer, dann kann das Abschieben von Hand sehr mühsam sein. Dann werden so genannte Abdrückschilde an den Maschinen vorgesehen, die an parallel zu den Wickelwellen verlaufenden Führungen gelagert sind und über Gewindespindeln, Ketten oder anderen Fördereinrichtungen motorisch bewegbar sind. Als Abdrückschilde werden hierbei Einrichtungen bezeichnet, die in den Bereich der Wickelwelle hinein bewegbar sind und mittels derer die Wickelhülsen und/oder die fertig gewickelten Rollen über die Wickelwelle verschiebbar sind. Während des Wickelvorgangs parken diese Schilde an der Antriebsseite im freien Raum zwischen einer äußerster Materialkante und dem Maschinengestell. Die Schilde sind mit einem hufeisenförmigen Gabelstück versehen, das die Jeweilige Wickelwelle eng, aber nicht berührend, umgreift. Damit wird sichergestellt, dass die Abdrückkraft der Schilde nicht nur gegen die Stirnfläche der Wickelrolle, sondern auch beziehungsweise ausschließlich gegen die Stirnfläche der Wickelhülse wirkt. Ein Teleskopieren, das heißt ein Verschieben des gewickelten Bandes relativ zur Hülse, der Wickelrollen durch das Abschieben mittels des Abdrückschildes wird dadurch vermieden.In a first example, the coiled rolls are pushed off by hand onto a supporting belt or onto a support shaft resting against the winding shaft, from which the winding rolls are later removed individually. If the bobbins are very heavy, then pushing them off by hand can be very tedious. Then so-called Abdrückschilde be provided on the machine, which are mounted on parallel to the winding shafts guides and motorized by means of threaded spindles, chains or other conveyors. As Abdrückschilde this means called devices which are movable into the region of the winding shaft and by means of which the winding tubes and / or the finished wound rollers are slidable over the winding shaft. During the winding process, these shields park on the drive side in free space between an outermost edge of the material and the machine frame. The shields are provided with a horseshoe-shaped fork, which engages the respective winding shaft tight, but not touching. This ensures that the pressure force of the shields not only acts against the end face of the winding roll, but also or exclusively against the end face of the winding tube. A telescoping, that is, a displacement of the wound tape relative to the sleeve, the winding rollers by pushing off by means of the Abdrückschildes is thereby avoided.

In einem weiteren Beispiel zum Aufbringen der Wickelhülsen wird jede Wickelhülse einzeln und nacheinander von Hand aufgesteckt und mit geeigneten Messmethoden, wie beispielsweise einem Messschieber oder einem Maßstab, an die Aufwickelposition geschoben. Für die Erkennung der richtigen Position sind vielfältige Hilfsmittel gebräuchlich: Von einem handmarkierten Strich und einem angelegten Maßstab über ein ausziehbares Maßband, wie in der DE 101 55 133 A1 beschrieben, wobei dass Maßband auch mit digitaler Anzeige der Position ausführbar ist, bis hin zu Laserlichtpunkten sind Verfahren bekannt und allgemein üblich.In a further example for applying the cores, each core is individually and sequentially plugged by hand and pushed with suitable measurement methods, such as a caliper or a scale, to the winding position. For the recognition of the correct position, a variety of tools are used: From a hand-marked line and a scale applied on an extendable tape measure, as in the DE 101 55 133 A1 wherein the measuring tape is also executable with digital display of the position, up to laser light points, methods are known and common practice.

Die Nachteile dieser Arbeitsweisen sind offenkundig, da diese Arbeitsweisen nicht wirtschaftlich sind, sind sie nur zu rechtfertigen, wenn die Anzahl der Wickelrollen je Wickelung, die auch als Wurf bezeichnet wird, nicht zu groß ist, die Grenze zur Unwirtschaftlichkeit liegt etwa bei 12 Rollen auf zwei Wickelwellen.The disadvantages of these operations are obvious, since these operations are not economical, they are only justified if the number of bobbins per winding, which is also referred to as throw, is not too large, the limit of inefficiency is about 12 rolls on two winding shafts.

Bei schmalen Schnittbreiten, womit allgemein eine größere Anzahl von Wickelrollen verbunden ist, ist die Verwendung von so genannten Coreboxen üblich. Coreboxen sind rinnenförmige Halbschalen mit halbkreisförmigen Kammern, in die die leeren Wickelhülsen eingelegt werden. Durch die Kammern stehen die Hülsen exakt rechtwinklig zur Rotationsachse. Auch entspricht der Kammerabstand genau der Schnittbreite. Oftmals sind die Coreboxen auch mit klappbaren oberen Halbschalen (Halbbox) versehen, so dass die leeren Wickelhülsen rundum geführt und gesichert sind. Diese Coreboxen werden mit den einllegenden Hülsen von Hand oder von Vorrichtungen getragen und über ein freies Ende Jeder Wickelwelle geschoben. Jetzt haben alle Wickelhülsen den korrekten Abstand zueinander. Nach dem Öffnen der oberen Halbbox wird die untere Corebox zuerst radial und dann axial aus dem Wickelbereich herausgenommen. Die Lösung mittels Coreboxen ist betriebssicher. Jedoch benötigt jede Schnittbreite eine dafür angefertigte Corebox. Somit kommen Coreboxen überwiegend nur für Standardbreiten in Frage, wie zum Beispiel bei Klebebendrollen.With narrow cutting widths, which is generally associated with a larger number of winding rolls, the use of so-called Coreboxen is common. Coreboxes are channel-shaped half-shells with semicircular chambers, in which the empty cores are inserted. Through the chambers, the sleeves are exactly perpendicular to the axis of rotation. Also, the chamber spacing corresponds exactly to the cutting width. Often the Coreboxen are also provided with hinged upper half shells (Halbbox), so that the empty cores are completely guided and secured. These coreboxes are carried with the inserting sleeves by hand or jigs and pushed over a free end of each winding shaft. Now all cores have the correct distance to each other. After opening the upper half box, the lower core box is first removed radially and then axially from the winding area. The solution using coreboxes is reliable. However, each cutting width requires a Corebox made for it. Thus, coreboxes come predominantly only for standard widths in question, as for example in adhesive end rolls.

WO 2005/023694 offenbart weiterhin ein Verfahren zum Positionieren mehreren Hülsen in einer Spulmaschine. WO 2005/023694 further discloses a method of positioning a plurality of sleeves in a winder.

Aufgabe der Erfindung ist es somit eine preisgünstige technische Lösung bereit zu stellen, um Wickelhülsen automatisch und in kürzester Zeit auf die Wickelwellen aufzuschieben und dort zu positionieren.The object of the invention is therefore to provide an inexpensive technical solution to postpone cores automatically and in no time on the winding shafts and position it.

Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst.The object is achieved by the features of claim 1.

Durch das erfindungsgemäße Verfahren ist nun die Möglichkeit geschaffen, die Wickelhülsen vollautomatisch auf der Wickelwelle zu verfahren und exakt zu positionieren. Hierbei kann die Wickelhülse mittels der Zange von den übrigen auf die Wickelwelle aufgeschobenen Wickelhülsen so weit entfernt werden, dass das Gabelstück des Abschiebeschildes zwischen die benachbarten Hülsen gelangen kann. Das Gabelstück fährt dabei über die Wickelwelle und gelangt in eine Position, in der es unmittelbar über der Wickelwelle befindliche gegen eine Stirnseite der Wickelhülse wirkt, so dass die Wickelhülse über die Wickelwelle verschiebbar ist. Das Gabelstück weist die Form einer zweizahnigen Gabel auf, wobei die Wickelwelle während des Eingriffs des Gabelstücks zwischen die beiden Zähne der Gabel gelangt und die Zähne und/oder die u-förmige Rundung der Gabel unmittelbar an der Wickelhülse anliegen. Die Zange ist am Abschiebeschild befestigt und ebenfalls gegen die Wickelwelle anstellbar und zwar so weit gegen die Wickelwelle anstellbar, dass die Greifer der Zange die Wickelhülse ergreifen, halten und über die Wickelwelle verschieben können.By means of the method according to the invention, it is now possible to move the winding tubes fully automatically on the winding shaft and to position them exactly. In this case, the winding tube can be so far away by means of the pliers of the other pushed onto the winding shaft winding sleeves that the fork piece of the Abschiebeschildes can get between the adjacent sleeves. The fork moves over the winding shaft and enters a position in which it is located directly above the winding shaft against a front side of the winding tube, so that the winding tube is slidable over the winding shaft. The fork has the shape of a bifurcated fork, wherein the winding shaft passes during the engagement of the fork between the two teeth of the fork and the teeth and / or the U-shaped curve of the fork abut directly on the winding tube. The pliers is attached to the Abschiebeschild and also against the winding shaft adjustable and although so far against the winding shaft adjustable so that the grippers of the pliers take the winding tube, hold and can move over the winding shaft.

In einem Vorratsbehälter 1, wie beispielsweise einem Magazin 1, sind leere Wickelhülsen 2 In großer Anzahl so gestapelt, dass die Rotationsachsen parallel zur Wickelwelle 5 liegen. Ein umlaufendes Transportband 3, das mit quer zu seiner Bandlaufrichtung befestigten Stegen ausgerüstet ist, erfasst nacheinander Wickelhülsen 2 aus dem Magazin 1 und bringt sie in koaxiale Position 4 mit der jeweiligen Wickelwelle 5.

Die zur Bestückung vorgesehene leere Wickelhülse 7 liegt nun direkt neben dem freien Ende 6 der Wickelwelle 5 in koaxialer Position. Eine Schiebevorrichtung 8, wie zum Beispiel ein Pneumatikzylinder 9 oder eine elektrisch betriebener Linearantrieb, schiebt jetzt die Wickelhülse 7 auf die Wickelwelle 5 und zieht sich sofort wieder zurück. Nun taktet das Förderband die nächste Wickelhülse 7 vom Transportband 3 in koaxiale Position zur Wickelwelle 5. Die Schiebevorrichtung 8 drückt nun diese Hülse 7 auf die Wickelwelle 5. Dabei wird die zuvor eingebrachte Hülse 7 durch die nachfolgende um eine Hülsenlänge weiter geschoben. Diese Vorgänge wiederholen sich gemäß dem eingestellten Programm solange, bis sich die erforderliche Anzahl von Leerhülsen auf der jeweiligen Wickelwelle 5 befindet.The Fig. 2 shows a plan view of the magazine 1, the conveyor belt 3, a winding shaft 5 and a pusher 8 with a pneumatic cylinder 9. The provided for assembly empty winding tube 7 is now located directly next to the free end 6 of the winding shaft 5 in the coaxial position. A pusher 8, such as a pneumatic cylinder 9 or an electrically operated linear drive, now pushes the winding tube 7 on the winding shaft 5 and retires immediately back. Now the conveyor belt clocks the next winding tube 7 from the conveyor belt 3 in a coaxial position to the winding shaft 5. The pusher 8 now presses this sleeve 7 on the winding shaft 5. The previously introduced sleeve 7 is pushed by the following by a sleeve length on. These operations are repeated in accordance with the set program until the required number of empty tubes on the respective winding shaft 5 is.

Nun kann das Magazin 1 und das Transportgerät 3 aus dem Wickelbereich zurückgezogen werden. Somit ist der erste Arbeitsschritt, Aufschieben der erforderlichen Wickelhülsen 2, 7 auf die Wickelwelle 5 abgeschlossen.Now the magazine 1 and the transport device 3 can be withdrawn from the winding area. Thus, the first step, pushing the required winding tubes 2, 7 is completed on the winding shaft 5.

In einem zweiten Arbeitsschritt werden die Hülsen 7 auf den Wickelwellen 5 positioniert. Dazu wird das Jeweilige Abdrückschild 10 zu einer Doppelfunktion herangezogen, indem durch eine Zange 12, die am äußeren Umfang einer Leerhülse 7 angreift und verfährt, ein Spalt 15 zwischen benachbarten Hülsen 7 entsteht, in den ein Gabeistück 14 eintaucht und damit die präzise Positionierung vornimmt, wie in Figur 3 dargestellt.In a second step, the sleeves 7 are positioned on the winding shafts 5. For this purpose, the respective Abdrückschild 10 is used to a dual function by a pair of pliers 12, the outer periphery of a Empty sleeve 7 attacks and moves, a gap 15 between adjacent sleeves 7 is formed, in which a Gabeistück 14 is immersed and thus makes the precise positioning, as in FIG. 3 shown.

Die bekannte Arbeitsweise der Abdrückschilde 10 ist weiter oben bereits erklärt. Diese Schilde 10 sind in quer zur Bandlaufrichtung, das heißt axial zur Wickelwelle 5, verlaufenden Führungen 11 gelagert und geführt. Die Führungen sind meist oberhalb der oberen und unterhalb der unteren Wickelwelle 5 angebracht. Außerdem sind diese Führungen durch motorische Antriebsmittel für die Abdrückschilde 10 ergänzt.
Um die Kosten für erfindungsgemäße Vorrichtung für die Wickelhülsenpositionierung zu sparen, werden die Abdrückschilde 10 entsprechend der Erfindung, in vorteilhafter Weise, auch für die Positionierung der Leerhülsen 2, 7, 13 herangezogen.The known operation of the Abdrückschilde 10 is already explained above. These shields 10 are mounted and guided in transversely to the strip running direction, that is, axially to the winding shaft 5, extending guides 11. The guides are usually mounted above the upper and below the lower winding shaft 5. In addition, these guides are supplemented by motor drive means for the Abdrückschilde 10.
In order to save the cost of the device according to the invention for the winding tube positioning, the Abdrückschilde 10 are used according to the invention, in an advantageous manner, for the positioning of the empty tubes 2, 7, 13.

Führung und Antrieb arbeiten mit einem Messglled und einem Rechenprogramm zusammen. Die Abdrückschilde 10 werden für die Positionierung der bereits auf den Wickelwellen 5 befindlichen Leerhülsen 13 zusätzlich mit einer Zange 12 ausgerüstet, mit der die leeren Hülsen 13 am äußeren Umfang gefasst werden können. Außerdem kann das hufeisenförmige, die Wickelwelle 5 umfassende Abschiebetell 14 soweit radial von der Jeweiligen Wickelwelle 5 zurückgezogen werden, dass es an den Leerhülsen berührungslos vorbeigefahren werden kann, wie in Fig. 5 dargestellt. Zum Positionieren der Hülsen 13 arbeiten die modifizierten Abdrückschilde 10 umgekehrt wie beim Abdrücken der Wickelrollen 7.Guidance and drive work together with a measuring device and a computer program. The Abdrückschilde 10 are additionally equipped for the positioning of the already on the winding shafts 5 empty tubes 13 with a pair of pliers 12, with the empty tubes 13 can be taken on the outer circumference. In addition, the horseshoe-shaped, the winding shaft 5 comprehensive Abschiebetell 14 can be radially retracted so far from the respective winding shaft 5 that it can be moved past the empty tubes contactless, as in Fig. 5 shown. To position the sleeves 13, the modified Abdrückschilde 10 work in reverse as in the printing of the winding rollers. 7

Das Abdrückschild 10 fährt mit der offenen Zange 12 und zurückgezogenem hufeisenförmigen Abdrückteil 14 über die zuerst aufgeschobene Wickelhülse 13. Die Zange 12 schließt und erfasst die erste Hülse 13. Nun bewegt sich das Schild 10 zusammen mit dieser Hülse 13 in Richtung Park- und Wickelposition, jedoch nur so weit, dass zwischen Leerhülse eins und Leerhülse zwei ein Spalt 15 entsteht. Dieser Spalt 15 ist etwas breiter als das hufeisenförmige Abschiebeteil 14, also ca. 25 mm. In diesen Spalt 15 taucht nun das hufeisenförmige Abschiebeteil 14 ein und die Zange 12 öffnet sich, wie in Figur 4 zu sehen.The Abdrückschild 10 moves with the open pliers 12 and withdrawn horseshoe-shaped Abdrückteil 14 on the first deferred winding tube 13. The pliers 12 closes and detects the first sleeve 13. Now moves the shield 10 together with this sleeve 13 in the park and winding position, however, only so far that between empty tube one and empty tube two, a gap 15 is formed. This gap 15 is slightly wider than the horseshoe-shaped Abschiebeteil 14, so about 25 mm. In this gap 15 now immerses the horseshoe-shaped Abschiebeteil 14 and the pliers 12 opens, as in FIG. 4 to see.

Alternativ kann zum Beginn der Positionierung mit der zuerst aufgeschobenen Hülse 13 mit der Positionierung der zuletzt aufgeschobenen Hülse 13 begonnen werden. Dann greift das hufeisenförmige Abschiebeteil 14 an die freie Stirnfläche der letzten Hülse 13 und schiebt diese mit der gesamten Säule von Wickelhülsen 13 auf die erste Position. Danach wird mit der Zange 12 die zweitletzte Hülse 13 erfasst und, wie oben beschrieben, ein Spalt 15 zwischen der letzten und vorletzten Hülse 13 geschaffen. Auch hierbei wird die restliche Hülsensäule verschoben. Der Vorgang wird bis zu der zuerst aufgeschobenen Hülse fortgesetzt. Diese Reihenfolge ist für den zeitlichen Ablauf vorteilhaft, da die Leerfahrten des Abdrückschildes 10 auf ein Minimum reduziert werden.Alternatively, the beginning of the positioning with the first pushed sleeve 13 with the positioning of the last deferred sleeve 13 can be started. Then the horseshoe-shaped Abschiebeteil 14 engages the free end face of the last sleeve 13 and pushes them with the entire column of winding tubes 13 to the first position. Thereafter, the second last sleeve 13 is detected with the pliers 12 and, as described above, a gap 15 between the last and penultimate sleeve 13 created. Again, the remaining sleeve column is moved. The process is continued until the first pushed sleeve. This sequence is advantageous for the timing, since the empty runs of Abdrückschildes 10 are reduced to a minimum.

Die Positionierung an einer Stirnfläche der Wickelhülsen 2, 7, 13 ist ein wesentlicher Bestandteil der Erfindung. Das hufeisenförmige oder gabelförmige Abschiebeteil 14 legt sich bei weiterer Fahrbewegung des jeweiligen Schildes 10 gegen eine Stirnfläche der zu positionierenden Wickelhülse 2, 7, 13. Sodann wird die gewünschte Position über das vorgegebene Programm angefahren. Der Vorgang wird so lange schrittweise wiederholt, bis alle auf der jeweiligen Wickelwelle 5 befindlichen Wickelhülsen 2, 7, 13 die erforderliche Position erreicht haben.The positioning on an end face of the winding tubes 2, 7, 13 is an essential part of the invention. The horseshoe-shaped or fork-shaped Abschiebeteil 14 sets with further travel movement of the respective shield 10 against an end face of the winding tube 2, 7, 13 to be positioned. Then, the desired position is approached via the predetermined program. The process is repeated step by step until all located on the respective winding shaft 5 cores 2, 7, 13 have reached the required position.

Die Verschiebung über das Abschiebeteil 14 und die Stlrnfläche der Hülse 2, 7,13 ist insoweit wichtig, als.alle Wickelhülsen 2, 7, 13, die meist aus Pappe bestehen, unvermeldbare Längentoleranzen haben. Es ist mit dem erfindungsgemäßen Verfahren slchergestellt, dass alle Wickelhülsen auf einer Wickelwelle einseitig auf einer exakten und in deckungsgleicher Position mit einer Schnittkante der zu wickelnden Bänder übereinstimmen. Nach der letzten Positionierfahrt fährt das jeweilige Abdrückschild 10 in seine Parkposition an der Antriebsseite. Nach vollendeter Wicklung agieren die Schilde 10 zunächst wieder als Abdrücker 10 für fertige Wickelrollen und anschließend wieder als Positionierer für die leeren Wickelhülsen 2, 7, 13.The displacement over the Abschiebeteil 14 and the Stlrnfläche the sleeve 2, 7,13 is important insofar as.alle winding tubes 2, 7, 13, which are usually made of cardboard, have unvermeldbare length tolerances. It is slchergestellt with the method according to the invention that all cores coincide on a winding shaft on one side on an exact and congruent position with a cutting edge of the belts to be wound. After the last positioning drive the respective Abdrückschild 10 moves to its parking position on the drive side. After completion of the winding, the shields 10 initially act again as a presser 10 for finished bobbins and then again as a positioner for the empty winding tubes 2, 7, 13th

Die Leistungsfähigkeit bezüglich Zeit und Positioniergenauigkeit und unter Berücksichtigung des geringen technischen Aufwandes ist ein wesentlicher Vorteil der Erfindung.The performance in terms of time and positioning accuracy and taking into account the low technical complexity is a significant advantage of the invention.
