Description

Die Erfindung betrifft eine Wickelmaschine zum Aufwickeln der einzelnen Bahnstreifen einer längsgeschnittenen Warenbahn, insbesondere einer Kunststoffolie, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a winding machine for winding up the individual web strips a longitudinally cut web, in particular a plastic film, according to the Preamble of claim 1.

Zum Aufwickeln der einzelnen Bahnstreifen einer längsgeschnittenen Warenbahn, beispielsweise einer Kunststoffolie, werden bekannterweise Wickelmaschinen eingesetzt, bei denen die beim Längsschneiden erzeugten Bahnstreifen wechselweise zwei getrennten Aufwickelgruppen zugeführt werden, die jeweils an einer Maschinenseite angeordnet sind. in jeder Aufwickelgruppe werden die Bahnstreifen zu Wickelrollen aufgewickelt, die mit koaxial fluchtenden Wickelachsen gehalten werden. Die Aufteilung der Bahnstreifen auf zwei Förderstrecken, die jeweils zu einer Aufwickelgruppe führen, ist erforderlich, um die Stirnseiten zweier benachbarter Wickelrollen beim Aufwickeln auf Abstand zu halten, um eine Reibung zwischen zwei Wickelrollen zu verhindern. Die Aufteilung der Bahnstreifen auf die beiden Förderstrecken erfolgt beim Ablauf von einer Separierwalze, die entweder zugleich als Schneidwalze beim Längsschneiden dient oder hinter der Längsschneideeinrichtung angeordnet ist.For winding up the individual web strips of a slit web, for example, a plastic film, are known to be winding machines used, in which the web strips produced during slitting alternately two separate take-up groups are fed, each on one machine side are arranged. in each winding group, the web strips become winding rolls wound, which are held with coaxially aligned winding axes. The Distribution of the lanes on two conveyor lines, each to a winding group lead is required to the end faces of two adjacent winding rolls Keep a distance when winding to avoid friction between two winding rollers to prevent. The lanes are divided between the two conveyor lines when running off a separating roller, which is also used as a cutting roller at the same time Longitudinal cutting is used or is arranged behind the longitudinal cutting device.

Zwischen der Separierwalze und den einzelnen Wickelstationen werden die Bahnstreifen von Führungswalzen umgelenkt. Beim Aufwickeln von Bahnstreifen aus Kunststoffolien dient üblicherweise als letzte Führungswalze eine Kontaktwalze, die pneumatisch gegen die jeweilige Wickelrolle angedrückt wird, um die an der Bahn haftende Luft abzuquetschen. Weiterhin ist es erforderlich, die Wickelrollen der einen Aufwickelgruppe gleichsinnig zu denen der anderen Aufwickelgruppe zu drehen, damit jeweils die gleichen Bahnseiten beim Aufwickeln innen bzw. außen liegen. The web strips are between the separating roller and the individual winding stations deflected by guide rollers. When winding up strips of plastic film usually serves as the last guide roller, a contact roller, the is pressed pneumatically against the respective winding roll in order to hold the on the web squeeze off sticking air. It is also necessary to use the winding rolls of one So that the winding group rotates in the same direction as those of the other winding group the same web sides lie inside or outside when winding.

Eine derartige Wickelmaschine der gattungsgemäßen Art ist in der DE 33 08 059-C beschrieben.Such a winding machine of the generic type is in DE 33 08 059-C described.

Bekannterweise ist es erforderlich, beim Aufwickeln einen anderen Bahnzug als beim Längsschneiden einzustellen. Um dies zu ermöglichen, müssen die Kontaktwalzen und die in Bahnlaufrichtung davor angeordneten Führungswalzen in einem ausreichend großen Winkel von den Bahnstreifen umschlungen sein, damit sie genügend an den Walzen haften.As is known, it is necessary to use a different web tension when winding than with To adjust slitting. To make this possible, the contact rollers and the guide rollers arranged in front of it in the web running direction are sufficient in one be wrapped in large angles by the lane strips so that they adhere to the Rolls stick.

In der Praxis hat es sich gezeigt, daß unterschiedliche Umschlingungsverhältnisse an den entsprechenden Walzen der beiden Förderstrecken zu Differenzen im Bahnzug beim Aufwickeln und damit zu Differenzen in der Wickelqualität in den beiden Aufwickelgruppen führen. Die Differenzen können nur konstruktiv aufwendig, beispielsweise mit Einzelantrieben für die Wickelrollen, korrigiert werden.In practice, it has been shown that different wrapping conditions on the corresponding rollers of the two conveyor lines to differences in the train at Winding up and thus differences in the winding quality in the two winding groups to lead. The differences can only be structurally complex, for example with Individual drives for the winding rolls are corrected.

Aus der DE 15 74 325-B ist eine Wickelmaschine zum Aufwickeln einzelner Bahnstreifen einer längsgeschnitten Warenbahn bekannt, die eine Längsschneideeinrichtung zum Unterteilen den Warenbahn in Bahnstreifen und ein Element zum Aufteilen der Bahnstreifen auf zwei getrennte Förderstrecken aufweist, die jeweils zu einer Aufwickelgruppe führen. In jeder Aufwickelgruppe werden Bahnstreifen zu Wickelrollen aufgewickelt, wobei jede der beiden Förderstrecken zu einer Aufwickelgruppe beim oder unmittelbar nach dem Aufteilen der Bahnstreifen mit je zwei Führungswalzen beginnt.DE 15 74 325-B describes a winding machine for winding up individual web strips a slit web known that a slitter for Divide the web into web strips and an element for dividing the web strips on two separate conveyor lines, each to a winding group to lead. In each winding group, web strips are wound into winding rolls, whereby each of the two conveyor lines to a winding group at or immediately after the division of the web strips begins with two guide rollers each.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Wickelmaschine so zu verbessern, daß die Bahnstreifen in den beiden Förderstrecken zu den beiden Aufwickelgruppen mit übereinstimmenden Umschlingungsverhältnissen an den jeweils entsprechenden Walzen geführt werden können.The invention has for its object to a generic winding machine improve that the web strips in the two conveyor lines to the two winding groups with matching looping ratios on the corresponding ones Rolls can be performed.

Diese Aufgabe wird mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of patent claim 1.

Die Unteransprüche enthalten bevorzugte, da besonders vorteilhafte Ausführungsformen der Erfindung. The subclaims contain preferred, since particularly advantageous, embodiments the invention.

Bei der Ausführungsform nach Patentanspruch 2 ist vor den beiden ersten Führungswalzen eine Separierwalze angeordnet, von der die beiden Gruppen von Bahnstreifen auf getrennten Strecken abgezogen werden. Die Separierwalze kann zugleich als Schneidwalze beim Längsschneiden dienen, oder es ist eine getrennte Separierwalze hinter der Längsschneideeinrichtung angeordnet. Die beiden getrennten Förderstrecken zu den jeweiligen ersten Führungswalzen verlaufen im wesentlichen symmetrisch zu dem durch die Mitte zwischen diesen verlaufenden Lot auf die gemeinsame Tangente, da das Lot zugleich eine Tangente an die Separierwalze ist. In the embodiment according to claim 2 is in front of the first two guide rollers a separating roller arranged from which the two groups of web strips be deducted from separate routes. The separating roller can also act as a cutting roller serve when slitting, or there is a separate separating roller behind the Longitudinal cutting device arranged. The two separate conveyor lines to the respective first guide rollers run essentially symmetrically to the through the middle between this perpendicular solder on the common tangent, since the solder is also a tangent to the separating roller.

Bei der Ausführungsform nach Figur 2 sind die beiden ersten Führungswalzen unmittelbar nebeneinander angeordnet. Die beiden Förderstrecken zu den verschiedenen Aufwickelgruppen verlaufen erst ab dem Ablauf von den ersten Führungswalzen getrennt. Bei markierungsunempfindlichen Warenbahnen können die beiden ersten Führungswalzen gegeneinander gepreßt werden, damit der Bahnzug zwischen den Aufwickelgruppen und der Längsschneideeinrichtung unterbrochen wird.In the embodiment according to FIG. 2, the two first guide rollers are arranged immediately next to each other. The two conveyor lines to the different Rewind groups only run from the first guide rollers Cut. The first two can be used for mark-insensitive webs Guide rollers are pressed against each other so that the web tension between the Winding groups and the slitter is interrupted.

Bei den Ausführungsformen nach den Ansprüchen 4 und 5 sind die Längendifferenzen zwischen entsprechenden Teilstrecken der beiden Förderstrecken gering gehalten, vorzugsweise stimmen die Streckenlängen im wesentlichen überein. Geringe, insbesondere übereinstimmende Längen in den entsprechenden Förderstrecken stellen sicher, daß die Unterschiede in den Luftgrenzschichten auf den Bahnstreifen gering gehalten werden, die zu einem unterschiedlichen Haftungsverhalten auf einer nachfolgenden Führungswalze führen würden. Weiterhin vereinfachen übereinstimmende Längen der beiden Förderstrecken einen Rollenwechsel, da vor dem Aufteilen angebrachte Klebestreifen gleichzeitig die beiden Aufwickelgruppen erreichen. Die Wickelmaschine braucht somit nur einmal angehalten zu werden.In the embodiments according to claims 4 and 5, the length differences are kept low between corresponding sections of the two conveyor lines, preferably the track lengths are essentially the same. low, in particular, set matching lengths in the corresponding conveyor lines sure that the differences in the air boundary layers on the lane are small are held that lead to a different liability behavior on a following guide roller would lead. Furthermore, matching simplify Length of the two conveyor lines a roll change because before dividing attached adhesive strips reach the two winding groups simultaneously. The The winding machine therefore only needs to be stopped once.

Die Wickelmaschine nach Anspruch 7 hat den Vorteil, daß die beiden Aufwickelgruppen in gleicher Höhe über dem Boden angeordnet werden können. Dies vereinfacht sowohl die Konstruktion, als auch die Bedienung der Maschine.The winding machine according to claim 7 has the advantage that the two winding groups can be arranged at the same height above the floor. This simplifies it both the construction and the operation of the machine.

Das Antreiben zumindest der jeweils zweiten Führungswalze gemäß Patentanspruch 8 ermöglicht es, den Bahnzug beim Längsschneiden auf den gewünschten Wert einzustellen.Driving at least the respective second guide roller according to claim 8 enables the web tension when slitting to the desired value adjust.

Die von einer nicht dargestellten Abwickelvorrichtung abgezogene Warenbahn 1, im Beispiel eine Kunststoffolie, wird von einer Längsschneideeinrichtung 2 in einzelne Bahnstreifen unterteilt, die auf zwei getrennten Förderstrecken 3, 4 jeweils zu einer Aufwickelgruppe geführt werden, die an beiden Seiten der Wickelmaschine angeordnet sind. In jeder Aufwickelgruppe werden die Bahnstreifen zu Wickelrollen 4, 5 aufgewickelt, die auf bekannte Weise von Tragelementen gehalten und von einem Drehantrieb gedreht werden, um die gewünschte Zugspannung beim Aufwickeln zu erzeugen. Wie in den Figuren mit den Pfeilen angedeutet, werden die Wickelrollen 5, 6 gleichsinnig gedreht, damit jeweils die gleichen Seiten der Bahnstreifen sich innen und außen in den Wickelrollen 5, 6 befinden. Bevorzugt sind die beiden Aufwickelgruppen in gleicher Höhe über dem Boden angeordnet, die Wickelrollen 5, 6 drehen sich somit in der gleichen Höhe.The withdrawn from a unwinding device 1, im Example of a plastic film, is cut by a slitter 2 into individual Railway strips divided into two separate conveyor lines 3, 4 each Winding group are performed, which are arranged on both sides of the winding machine are. In each winding group, the web strips become winding rolls 4, 5 wound, which is held in a known manner by support elements and by a Rotary drive can be rotated to the desired tension when winding produce. As indicated by the arrows in the figures, the winding rolls 5, 6 rotated in the same direction, so that the same sides of the web strips are inside and are located outside in the winding rollers 5, 6. The two winding groups are preferred arranged at the same height above the floor, the winding rollers 5, 6 thus rotate at the same height.

Als Längsschneideeinrichtung wird nach den Ausführungsbeispielen eine Längsschneidewalze 7 verwendet, die bei dem Ausführungsbeispiel nach Figur 1 zugleich als Separierwalze dient. Alternativ kann im Anschluß an eine Längsschneideeinrichtung eine getrennte Separierwalze angeordnet werden, von der die Bahnstreifen auf die beiden Förderstrecken 3, 4 aufgeteilt werden. In Figur 2 ist eine weitere mögliche Ausführungsform dargestellt, bei der die Aufteilung der Bahnstreifen an den ersten Führungswalzen 8, 8', also ohne eine eigene Separierwalze erfolgt.According to the exemplary embodiments, a longitudinal cutting roller is used as the longitudinal cutting device 7 used, the same in the embodiment of Figure 1 serves as a separating roller. Alternatively, following a slitter a separate separating roller can be arranged, from which the web strips on the two conveyor lines 3, 4 are divided. Another possible one is shown in FIG Embodiment shown, in which the division of the web strips on the first Guide rollers 8, 8 ', that is, without its own separating roller.

Unmittelbar nach dem Aufteilen der Bahnstreifen (Figur 1) oder beim Aufteilen der Bahnstreifen (Figur 2) beginnen die beiden Förderstrecken 3, 4 jeweils mit einer ersten Führungswalze 8, 8', von denen die Bahnstreifen jeweils nach außen umgelenkt werden, so daß die beiden Förderstrecken 3, 4 zunächst voneinander weg verlaufen. Die beiden ersten Führungswalzen 8, 8' haben bevorzugt den gleichen Durchmesser und werden mit dem gleichen Winkel α von den Bahnstreifen umschlungen.Immediately after dividing the web strips (Figure 1) or when dividing the Railway strips (Figure 2), the two conveyor lines 3, 4 each start with a first Guide roller 8, 8 ', each of which deflects the web strip outwards are so that the two conveyor lines 3, 4 initially run away from each other. The first two guide rollers 8, 8 'preferably have the same diameter and are wrapped at the same angle α by the web strips.

Mit einem Abstand L1, L1' folgt jeweils auf die erste Führungswalze 8, 8' eine zweite Führungswalze 9, 9', von denen die Bahnstreifen jeweils wieder zur Maschinenmitte hin umgelenkt werden. Bevorzugt haben die beiden zweiten Führungswalzen 9, 9' den gleichen Durchmesser und werden mit dem gleichen Umschlingungswinkel β von den Bahnstreifen umlaufen. Wesentlich ist, daß die beiden zweiten Führungswalzen 9, 9' eine gemeinsame Tangente T mit den beiden ersten Führungswalzen 8, 8' besitzen, und daß die Bahnstreifen den ersten Führungswalzen 8, 8' im wesentlichen symmetrisch zu dem durch die Mitte zwischen den beiden ersten Führungswalzen 8, 8' verlaufenden Lot O auf die gemeinsame Tangente T zugeführt werden. Dies ermöglicht es, sowohl an den Walzen 8, 8', als auch an den Walzen 9, 9' jeweils übereinstimmende Umschlingungsverhältnisse einzustellen. Damit die Wickelrollen 5,6 der beiden Aufwickelgruppen gleichsinnig rotieren, sind die beiden zweiten Führungswalzen 9, 9' auf verschiedenen Seiten der gemeinsamen Tangente T angeordnet.The first guide roller 8, 8 'is followed by a second one at a distance L1, L1' Guide roller 9, 9 ', each of which the web strip back to the machine center be redirected. The two second guide rollers 9, 9 'preferably have the same diameter and are with the same wrap angle β from the Run around the lane. It is essential that the two second guide rollers 9, 9 ' have a common tangent T with the first two guide rollers 8, 8 ', and that the web strips the first guide rollers 8, 8 'substantially symmetrical to the middle between the two first guide rollers 8, 8 ' perpendicular Lot O are fed to the common tangent T. This allows both on the rollers 8, 8 ', as well as on the rollers 9, 9' to set corresponding looping ratios. So that the winding rollers 5.6 of the two winding groups rotate in the same direction, are the two second guide rollers 9, 9 'arranged on different sides of the common tangent T.

Bei der Ausführungsform nach Figur 1 haben die ersten Führungswalzen 8, 8' einen gewissen Abstand voneinander. Sie sind so relativ zum Lot 0 angeordnet, daß ihre beiden Abstände a, a' von Lot 0 sich um weniger als 20 % des kleinsten Abstands unterscheiden. Vorzugsweise sind die beiden Abstände a, a' im wesentlichen gleich, wie in Figur 1 dargestellt ist. Die Bahnstreifen werden mit wachsendem Abstand von dem Lot O den ersten Führungswalzen 8, 8' von der Separierwalze 7 zugeführt. Damit dies möglich ist, ist das Lot O zugleich eine Tangente an die Separierwalze.In the embodiment according to FIG. 1, the first guide rollers 8, 8 'have one some distance from each other. They are so arranged relative to Lot 0 that their two distances a, a 'from Lot 0 are less than 20% of the smallest distance differ. Preferably, the two distances a, a 'are essentially the same, as shown in Figure 1. The lane strips are spaced from the first guide rollers 8, 8 'from the separating roller 7 to the solder O. In order to this is possible, the solder O is at the same time a tangent to the separating roller.

Bei der Ausführungsform nach Figur 2 liegen die beiden ersten Führungswalzen 8, 8' unmittelbar nebeneinander. Sie können umfänglich gegeneinander gepreßt werden, um die Bahnzüge zu unterbrechen. Die Bahnstreifen verlaufen daher auf der Förderstrecke zu den Führungswalzen 8, 8' im Lot O.In the embodiment according to FIG. 2, the two first guide rollers 8, 8 ' right next to each other. They can be pressed against each other extensively, to interrupt the train trains. The lanes therefore run on the conveyor line to the guide rollers 8, 8 'in Lot O.

Die Abstände L1, L1' der zweiten Führungswalzen 9, 9' von den ersten Führungswalzen 8, 8' unterscheiden sich um weniger als 20 % des kleisten Abstands L1, L1'. Vorzugsweise sind die beiden Abstände L1, L1' im wesentlichen gleich, und die zweiten Führungswalzen 9, 9' sind mit im wesentlichen gleichem Abstand vom Lot 0 auf verschiedenen Seiten der Tangente T angeordnet.The distances L1, L1 'of the second guide rollers 9, 9' from the first guide rollers 8, 8 'differ by less than 20% of the narrowest distance L1, L1'. Preferably, the two distances L1, L1 'are essentially the same, and the second guide rollers 9, 9 'are at substantially the same distance from the perpendicular 0 arranged on different sides of the tangent T.

Zumindest die beiden zweiten Führungswalzen 9, 9' jeder Förderstrecke, bevorzugt auch die ersten Führungswalzen 8, 8', sind mit einem Drehantrieb verbunden. Sie werden so angetrieben, daß sich die gewünschten Bahnzüge beim Längsschneiden und Aufwickeln einstellen.At least the two second guide rollers 9, 9 'of each conveyor section are preferred the first guide rollers 8, 8 'are also connected to a rotary drive. she are driven so that the desired web trains when slitting and adjust winding.

Jeweils im Anschluß an die zweite Führungswalze 9, 9' folgt eine dritte Führungswalze 10, 10', die bevorzugt als gegen die jeweilige Wickelrolle 5, 6 andrückbare Kontaktwalzen ausgebildet sind. Die beiden dritten Führungswalzen 10, 10' haben den gleichen Durchmesser und werden in einen gleichen Winkel γ von den Bahnstreifen umschlungen, der bei den Ausführungsbeispielen ca. 180° beträgt. Sie sind so angeordnet, daß sich die Längen L2, L2' in beiden Förderstrecken zwischen ihnen und der zugehörigen zweiten Führungswalze 9, 9' sich um weniger als 20 % der kleinsten Länge L2, L2' unterscheiden. Vorzugsweise sind die beiden Längen L2, L2' im wesentlichen gleich. Besonders vorteilhaft ist die Ausgestaltung, falls die Förderstrekken zu den dritten Führungswalzen 10, 10' auch parallel zueinander verlaufen und die Gerade durch ihre Mittelpunkte horizontal verläuft. Die beiden Aufwickelgruppen mit den Wickelrollen 5, 6 sind dann symmetrisch zueinander in gleicher Höhe in der Wickelmaschine angeordnet. Dies vereinfacht sowohl die Konstruktion als auch die Bedienung der Maschine.A third guide roller follows in each case after the second guide roller 9, 9 ' 10, 10 ', which is preferably pressed against the respective winding roll 5, 6 Contact rollers are formed. The two third guide rollers 10, 10 'have the same diameter and are at an equal angle γ from the web strip entwined, which is approximately 180 ° in the exemplary embodiments. You are so arranged that the lengths L2, L2 'in both conveyor lines between them and the associated second guide roller 9, 9 'is less than 20% of the smallest Differentiate length L2, L2 '. Preferably, the two lengths L2, L2 'in essentially the same. The configuration is particularly advantageous if the conveyor lines to the third guide rollers 10, 10 'also run parallel to each other and the Runs horizontally precisely through their centers. The two winding groups with the winding rollers 5, 6 are then symmetrical to each other at the same height in the Winding machine arranged. This simplifies both the design and the Operation of the machine.

Konstruktionsbedingt lassen sich auf den beiden Förderstrecken 3, 4 nicht immer exakt übereinstimmende Umschlingungsverhältnisse an den Walzen 8, 8' bzw. 9, 9' bzw. 10, 10' einstellen. Falls Abweichungen von der Idealsituation mit exakt übereinstimmenden Umschlingungsverhältnissen an den entsprechenden Walzen erforderlich sind, werden sie so gering gehalten, daß die Unterschiede der entsprechenden Winkel α, β, γ kleiner als 20 % des jeweils kleineren Winkels betragen.Due to the design, the two conveyor lines 3, 4 cannot always be used exactly matching wrapping conditions on the rollers 8, 8 'or 9, 9' or 10, 10 '. If there are deviations from the ideal situation with exact matching wrap ratios on the corresponding rollers necessary, they are kept so small that the differences of the corresponding Angles α, β, γ are less than 20% of the respective smaller angle.
