Description

Die Erfindung betrifft eine Wickelmaschine gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a winding machine according to the preamble of claim 1.

Eine solche Wickelmaschine ist durch die DE-PS 32 43 994 bekannt. Mit der dort vorgesehenen Trennvorrichtung soll ein sicheres Durchtrennen der Warenbahn an definierter Stelle erzielt werden, damit der hierdurch geschaffene Bahnanfang eine ausreichende Länge zum Befestigen an einer neuen Wickelhülse hat. Die Trennvorrichtung muß daher an einer Stelle des Ablaßtisches angeordnet sein, an der sie an der zwischen der Walze und der auf dem Ablaßtisch befindlichen Wickelrolle verlaufenden Bahn angreifen kann. Dabei darf die Trennvorrichtung den Übergang der Wickelrolle von der Walze auf den Ablaßtisch nicht behindern. Außerdem darf sie keine Schäden an den äußeren Lagen der Wickelrolle hervorrufen. Ferner muß die Trennvorrichtung für Wartungszwecke gut zugänglich sein. Schließlich muß die Trennvorrichtung aber so geschützt angeordnet sein, daß Verletzungen des Bedienungspersonals der Wickelmaschine sicher vermieden werden.Such a winding machine is known from DE-PS 32 43 994. With the separating device provided there, a reliable severing of the web at a defined point is to be achieved, so that the web start created thereby has a sufficient length for fastening to a new winding tube. The separating device must therefore be arranged at a point on the lowering table where it can engage the web running between the roller and the winding roll located on the lowering table. The separating device must not hinder the transition of the winding roll from the roller to the discharge table. In addition, it must not cause any damage to the outer layers of the winding roll. Furthermore, the separator must be easily accessible for maintenance purposes. Finally, the separating device must be arranged so that injuries to the operator of the winding machine can be safely avoided.

Der Erfindung liegt daher die Aufgabe zugrunde, diese zum Teil miteinander in Widerspruch stehenden Forderungen bei der Gestaltung einer konstruktiv einfachen Trennvorrichtung zu erfüllen.The object of the invention is therefore to meet these partially contradicting requirements when designing a structurally simple separating device.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichneten Merkmale gelöst.This object is achieved by the features characterized in claim 1.

Die Lösung ist insofern vorteilhaft, als die Trennvorrichtung zum einen während des Nichtgebrauchs im Ablaßtisch aufgenommen ist (Ruhestellung), wo sie die Übergabe der Wickelrolle auf den Ablaßtisch nicht stört und der leichten Zugänglichkeit entzogen ist, so daß Unfälle sicher vermieden werden. Zum anderen kann die Trennvorrichtung in eine Lage (Arbeitsstellung) gebracht werden, in der sie besonders wirkungsvoll ist und eine sichere Trennung der Bahn erzielt wird.The solution is advantageous in that the separating device is accommodated in the discharge table when not in use (rest position), where it does not interfere with the transfer of the winding roll to the discharge table and is out of the way of easy access, so that accidents can be avoided safely. On the other hand, the separating device can be brought into a position (working position) in which it is particularly effective and a safe separation of the web is achieved.

Durch die im Anspruch 1 angegebene Maßnahme wird einerseits eine stabile Lagerung der Trennvorrichtung am Ablaßtisch und andererseits eine geschützte Anordnung der Leiste mit Trennelement erzeugt. Dabei wird infolge der Anordnung gemäß Anspruch 1 ein behinderungsfreies Überführen der Wickelrolle ohne Schädigung von Bahnlagen erreicht.The measure specified in claim 1 produces a stable mounting of the separating device on the drain table on the one hand and a protected arrangement of the strip with separating element on the other hand. As a result of the arrangement according to claim 1, an unobstructed transfer of the winding roll is achieved without damaging the web layers.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments of the invention are characterized in the subclaims.

Mit dem in Anspruch 2 angegebenen Trennelement wird ein bewährtes Bauteil verwendet, welches mit seinen Zahnspitzen ohne großen Widerstand in die gestraffte Warenbahn einzudringen vermag und diese perforiert, so daß es zur sicheren Trennung der bahn an dieser Stelle kommt.With the separating element specified in claim 2, a tried-and-tested component is used which, with its tooth tips, can penetrate the taut web without great resistance and perforates it, so that the web is reliably separated at this point.

Mit der im Anspruch 3 angegebenen Maßnahme ist ein schneller Austausch eines verschlissenen Trennelementes möglich. Diese Wartungsarbeit wird zweckmäßigerweise in der Arbeitsstellung der Trennvorrichtung vorgenommen, weil dann das Trennelement gut zugänglich ist.With the measure specified in claim 3, a quick replacement of a worn separating element is possible. This maintenance work is expediently carried out in the working position of the separating device because the separating element is then easily accessible.

Die im Anspruch 4 gekennzeichnete Betätigungsvorrichtung erfüllt mit wenig konstruktivem Aufwand den Zweck, die Trennvorrichtung in ihre zwei Stellungen zu bewegen. Nennenswerte Kräfte sind dabei nicht aufzubringen, so daß eine relativ kleine Pneumatik-Einheit hierfür genügt.The actuating device characterized in claim 4 fulfills the purpose of moving the separating device into its two positions with little design effort. Significant forces cannot be applied, so that a relatively small pneumatic unit is sufficient for this.

Ein Ausführungsbeispiel der Erfindung ist nachstehend anhand der Zeichnung näher erläutert. Es zeigen:

Die in Fig. 1 mit Ziffer 10 bezeichnete Wickelmaschine weist eine Zentralwalze 11 sowie beiderseits dieser je eine parallel verlaufende Hilfswalze 12 und 13 auf. In ihrem oberen Zwickel bilden die Walzen 11 und 12 sowie 11 und 13 je ein Wickelbett 14 bzw. 15. Eine der Zentralwalze 11 von unten zugeführte Warenbahn 16 wird durch eine nicht dargestellte Längsschneideeinrichtung in zwei Bahnstreifen 16.1 und 16.2 geschnitten. Diese Streifen 16.1. und 16.2 werden im entsprechenden Wickelbett 14 bzw. 15 zu je einer Rolle 17 und 18 aufgewickelt, und zwar der über die Zentralwalze 11 von oben in das Wickelbett 14 laufende Bahnstreifen 16.1 zur Wickelrolle 17, während aus dem von unten in das Wickelbett 15 laufenden Streifen 16.2 die Wickelrolle 18 hergestellt wird.The winding machine designated by number 10 in FIG. 1 has a central roller 11 and on both sides of this a respective auxiliary roller 12 and 13 running in parallel. The rolls 11 and 12 and 11 and 13 each form a winding bed 14 and 15 in their upper gusset. A web 16 fed to the central roller 11 from below is cut into two web strips 16.1 and 16.2 by a longitudinal cutting device, not shown. These strips 16.1. and 16.2 are wound into a respective roll 17 and 18 in the corresponding winding bed 14 or 15, namely the web strip 16.1 running from above into the winding bed 14 via the central roller 11 to the winding roll 17, while the strip running from below into the winding bed 15 16.2 the winding roll 18 is manufactured.

Dem Wickelbett 15 ist eine um die Hilfswalze 13 von unten her einfahrbare Vorrichtung 19 zum Abtrennen des Streifens 16.2 von der Warenbahn 16 zugeordnet. Eine derartige Trennvorrichtung 19 ist ausführlich in der DE-PS 31 09 587 beschrieben. Bei einem Wechsel fertiger Wickelrollen 17 und 18 sind neue Wickelhülsen 20 auf weiter unten beschriebene Weise in das jeweilige Wickelbett 14 bzw. 15 einführbar.The winding bed 15 is associated with a device 19 which can be moved in from underneath the auxiliary roller 13 to separate the strip 16.2 from the web 16. Such a separation device 19 is described in detail in DE-PS 31 09 587. When changing finished winding rolls 17 and 18, new winding tubes 20 can be inserted into the respective winding bed 14 or 15 in the manner described below.

Beiderseits jeder Hilfswalze 12 und 13 befindet sich je ein Ablaßtisch 21 bzw.22 zum Aufnahmen der fertigen Wickelrollen 17 bzw. 18 beim Wickelwechsel. Zum Ausstoßen der Wickelrollen 17 bzw. 18 aus dem jeweiligen Wickelbett 14 bzw. 15 sind oberhalb der Zentralwalze 11 Ausstoßhebel 23 und 24 angeordnet. Dabei werden die Wickelrollen 17 bzw. 18 über die entsprechende Hilfswalze 12 bzw. 13 abgewälzt und in den jeweiligen, in seiner Aufnahmestellung gezeichneten Ablaßtisch 21 bzw. 22 gerollt. Die Ablaßtische 21 und 22 sind in Pfeilrichtung bewegbar, um die Wickelrollen 17 und 18 aus der Maschine 10 abzulegen.On both sides of each auxiliary roller 12 and 13 there is a discharge table 21 and 22 respectively for receiving the finished winding rollers 17 and 18 when changing the winding. To eject the winding rollers 17 and 18 from the respective winding bed 14 and 15 11 ejection levers 23 and 24 are arranged above the central roller. The winding rollers 17 and 18 are rolled over the corresponding auxiliary roller 12 and 13 and rolled into the respective discharge table 21 and 22 shown in its receiving position. The discharge tables 21 and 22 can be moved in the direction of the arrow in order to deposit the winding rolls 17 and 18 from the machine 10.

Die Hebel 23 und 24 sind mit Spannzangen 25 bzw. 26 versehen, mit denen sie nach Rückkehr in Pfeilrichtung in ihre Ruhestellung neue Wickelhülsen 20 (in der Position 20′) aufnehmen können. Diese neuen Wickelhülsen 20 werden auf einer oberhalb der Zentralwalze 11 verlaufenden Schiene 27 bereitgestellt. Beim Rollenwechsel werden die neuen Wickelhülsen 20 (in der Position 20˝) beidendig von nicht dargestellten Spannköpfen erfaßt und nach der Freigabe durch die Spannzangen 25 und 26 in das jeweilige Wickelbett 14 bzw. 15 abgesenkt. Eine derartige Maschinenausrüstung zur Hülseneingabe ist aus der DE-PS 35 40 490 bekannt. Im übrigen ist der prinzipielle Aufbau der Wickelmaschine in der eingangs erwähnten DE-PS 32 43 994 ausführlich beschrieben.The levers 23 and 24 are provided with collets 25 and 26, respectively, with which they can accommodate new winding tubes 20 (in the position 20 ') after returning in the direction of the arrow to their rest position. These new winding tubes 20 are provided on a rail 27 running above the central roller 11. When changing the reel, the new winding tubes 20 (in the position 20˝) are gripped at both ends by clamping heads (not shown) and, after being released by the collets 25 and 26, are lowered into the respective winding bed 14 and 15, respectively. Such machine equipment for sleeve input is known from DE-PS 35 40 490. Otherwise, the basic structure of the winding machine is described in detail in the aforementioned DE-PS 32 43 994.

Die Wickelmaschine 10 ist außerdem mit einer entlang dem walzennahen Randbereich des Ablaßtisches 21 angeordneten Vorrichtung 28 zum Trennen der Wickelrollen 17 vom Bahnstreifen 16.1, welcher dem Wickelbett 14 zuläuft, ausgestattet. Wie man aus der vergrößerten Darstellung in Fig. 2 deutlich erkennt, ist die Trennvorrichtung 28 in eine die Wickelrolle 17 stützende Platte 29 des Ablaßtisches 21 eingelassen. Die Stützplatte 29 hat in ihrem walzennahen Randbereich eine maschinenbreite Ausnehmung 30, in der eine parallel zur Walze 12 verlaufende Leiste 31 mit mehreren über ihre Gesamtlänge verteilten, mit der Stützplatte 29 verschraubten Topfscharnieren 32 schwenkbar gelagert ist. Entlang der walzenseitigen, freien Randzone der Leiste 31 ist ein Element 33 zum Trennen des zwischen der Zentralwalze 11 und der auf dem Ablaßtisch 21 befindlichen Wickelrolle 17 verlaufenden Warenbahnstreifens 16.1 mit Schrauben 34 befestigt. Das Trennelement 33 besteht aus einer gezahnten Klinge, die zweckmäßigerweise über die mehrere Meter betragende Maschinenbreite in mehrere Einzelelemente unterteilt ist. Als Trennelement kann aber auch ein Sägedraht, ein Hitzdraht oder eine Messerklinge Verwendung finden.The winding machine 10 is also equipped with a device 28 arranged along the edge region of the discharge table 21 near the rollers for separating the winding rolls 17 from the web strip 16.1, which runs towards the winding bed 14. As can clearly be seen from the enlarged illustration in FIG. 2, the separating device 28 is embedded in a plate 29 of the discharge table 21 which supports the winding roller 17. The support plate 29 has in its edge region near the roller a machine-wide recess 30 in which a strip 31 running parallel to the roller 12 also has a plurality of concealed hinges 32, which are distributed over their entire length and are screwed to the support plate 29, are pivotably mounted. Along the roller-side, free edge zone of the strip 31, an element 33 for separating the web strip 16.1 running between the central roller 11 and the winding roll 17 located on the discharge table 21 is fastened with screws 34. The separating element 33 consists of a toothed blade which is expediently divided into several individual elements over the machine width of several meters. A saw wire, a hot wire or a knife blade can also be used as the separating element.

Die Trennvorrichtung 28 ist mit einer Betätigungsvorrichtung 35 verbunden. Hierzu ist die Leiste 31 der Trennvorrichtung 28 an wenigstens einem ihrer beiden Ende mit einem Hebelarm 36 versehen, an dem eine am Ablaßtisch 21 gelagerte, pneumatisch betätigbare Kolben-Zylinder-Einheit 37 mit ihrer Kolbenstange 38 angreift.The separating device 28 is connected to an actuating device 35. For this purpose, the strip 31 of the separating device 28 is provided at at least one of its two ends with a lever arm 36, on which a pneumatically actuatable piston-cylinder unit 37 mounted on the discharge table 21 engages with its piston rod 38.

Während des Wickelvorgangs in der Maschine 10 befindet sich die Leiste 31 in ihrer mit strichpunktierten Linien in Fig. 2 gezeichneten Ruhestellung. In dieser Stellung ist die Leiste 31 zusammen mit dem Trennelement 33 völlig von der Ausnehmung 30 aufgenommen, so daß die obere Seite der Leiste 31, über welche die Wickelrolle 17 beim Entfernen aus der Maschine 10 abrollt, mit der entsprechenden Seite der Stützplatte 29 fluchtet. Mit der Betätigungsvorrichtung 35 kann die Trennvorrichtung 28 in ihre Arbeitsstellung (mit ausgezogenen Linien in Fig. 2 dargestellt) bewegt werden. Dabei tritt die Leiste 31 mit ihrem Trennelement 33 aus der Ausnehmung 30 des Ablaßtisches 21 heraus und nimmt in der erwähnten Stellung einen Winkel von etwa 60° zur Oberseite der Stützplatte 29 ein.During the winding process in the machine 10, the bar 31 is in its rest position drawn with dash-dotted lines in FIG. 2. In this position, the bar 31 together with the separating element 33 is completely received by the recess 30, so that the upper side of the bar 31, via which the winding roller 17 rolls when removed from the machine 10, is flush with the corresponding side of the support plate 29. With the actuating device 35, the separating device 28 can be moved into its working position (shown in solid lines in FIG. 2). Here, the strip 31 with its separating element 33 comes out of the recess 30 of the drain table 21 and, in the position mentioned, makes an angle of approximately 60 ° to the upper side of the support plate 29.

Beim Wickelwechsel werden im Maschinenstillstand die fertigen Wickelrollen 17 und 18 mit den Ausstoßhebeln 23 und 24 aus dem jeweiligen Wickelbett 14 und 15 über die Hilfswalzen 12 und 13 hinweg auf die entsprechenden Ablaßtische 21 und 22 gewälzt. Im Wickelbett 15 ist kurz zuvor die Trennvorrichtung 19 in ihre in Fig. 1 dargestellte Arbeitsstellung gebracht worden. Die Wickelrolle 18 ist daher bereits vom Warenbahnstreifen 16.2 abgetrennt. Unterdruck in der einen mit Bohrungen durchbrochenen Mantel aufweisenden Zentralwalze 11 hält diesen Bahnstreifen an der Walze fest, so daß die Trennvorrichtung 19 in Pfeilrichtung aus dem Wickelbett 15 bewegt werden kann, um dort eine neue Wickelhülse 20 einzubringen und mit dem Bahnstreifen 16.2 zu verbinden.When changing the winding, the finished winding rolls 17 and 18 with the ejection levers 23 and 24 are rolled out of the respective winding bed 14 and 15 over the auxiliary rollers 12 and 13 onto the corresponding discharge tables 21 and 22 when the machine is at a standstill. In the winding bed 15, the separating device 19 has just been brought into its working position shown in FIG. 1. The winding roll 18 is therefore already separated from the web strip 16.2. Negative pressure in the central roller 11 with a perforated jacket holds this web strip firmly on the roller, so that the separating device 19 can be moved in the direction of the arrow from the winding bed 15 in order to insert a new winding tube 20 there and connect it to the web strip 16.2.

Beim Bewegen der Wickelrolle 17 aus dem Wickelbett 14 auf den Ablaßtisch 21 befindet sich dagegen die Trennvorrichtung 28 in ihrer Ruhestellung. Sobald die Wickelrolle 17 ihre in Fig. 1 dargestellte Endlage auf dem Ablaßtisch 21 einnimmt, wird mit der Betätigungsvorrichtung 35 die Trennvorrichtung 28 in ihre Arbeitsstellung gebracht. Dabei greift das Trennelement 33 der Trennvorrichtung 28 an dem sich von der Zentralwalze 11 über das Wickelbett 14 und die Hilfswalze 12 zu der fertigen Wickelrolle 18 erstreckenden Bahnstreifen 16.1 an. Das Trennen des Warenbahnstreifens 16.1 kann durch Absenken der von den Spannköpfen erfaßten neuen Wickelhülse 20 in das Wickelbett 14 erfolgen. Dabei greift die Wickelhülse 20 am Warenbahnstreifen 16.1 an und strafft diesen, so daß das Trennelement 33 mit seinen Zähnen in den Bahnstreifen eindringt und diesen perforiert. Die weitere Bewegung der neuen Wickelhülse 20 führt zum Durchtrennen des Warenbahnstreifens 16.1 entlang dem Trennelement 33.When moving the winding roller 17 from the winding bed 14 to the discharge table 21, however, the separator 28 is in its rest position. As soon as the winding roll 17 assumes its end position shown in FIG. 1 on the discharge table 21, the separating device 28 is brought into its working position with the actuating device 35. The separating element 33 of the separating device 28 engages on the web strips 16.1 which extend from the central roll 11 via the winding bed 14 and the auxiliary roll 12 to the finished winding roll 18. The web strip 16.1 can be separated by lowering the new winding tube 20, which is gripped by the clamping heads, into the winding bed 14. The winding sleeve 20 engages and tightens the web strip 16.1, so that the separating element 33 penetrates with its teeth into the web strip and perforates it. The further movement of the new winding tube 20 leads to the severing of the web strip 16.1 along the separating element 33.

Der Trennvorgang kann auch durch Schwenken des Ablaßtisches 21 in Pfeilrichtung hervorgerufen werden. Hierbei wird ebenfalls der Warenbahnstreifen 16.1 gestrafft und am Trennelement 33 der Trennvorrichtung 28 durchtrennt. Zum sicheren Straffen des Warenbahnstreifens 16.1 wird die Zentralwalze 11 bei beiden Varianten des Trennvorganges in Bremsstellung gehalten und die Schiene 27 auf die Walze aufgesetzt, um den Bahnstreifen dort festzuhalten. Das Befestigen des derart gebildeten neuen Bahnanfangs des Warenbahnstreifens 16.1 an der neuen Wickelhülse 20 kann durch Kleben, Anheften od.dgl. erfolgen. Die Wickelmaschine 10 ist nach dem Ablegen der Wickelrollen 17 und 18 wieder wickelbereit.The separation process can also be brought about by pivoting the discharge table 21 in the direction of the arrow. Here, too, the web strip 16.1 is tightened and on the separating element 33 Cutting device 28 severed. In order to tighten the web strip 16.1 securely, the central roller 11 is held in the braking position in both variants of the separating process and the rail 27 is placed on the roller in order to hold the web strip there. The attachment of the new web start of the web strip 16.1 formed in this way to the new winding tube 20 can be done by gluing, tacking or the like. respectively. The winding machine 10 is ready for winding again after the winding rollers 17 and 18 have been put down.

Die beschriebene Trennvorrichtung 28 ist nicht nur bei Wickelmaschinen 10 mit drei Walzen 11, 12 und 13 verwendbar. Sind kann eingesetzt werden bei Maschinen mit zwei Walzen (sogenannten Doppeltragwalzen-Wickelmaschinen) oder auch bei Maschinen mit lediglich einer Walze (sogenannten Stützwalzen-Wickelmaschinen). Es ist dabei nicht erforderlich, bei derartigen Maschinen die zulaufende Warenbahn in Streifen zu zerteilen. Die beschriebene Trennvorrichtung kann auch zum Durchtrennen einer Warenbahn in voller Breite benutzt werden.The separation device 28 described can not only be used in winding machines 10 with three rollers 11, 12 and 13. Can be used on machines with two rollers (so-called double carrier roller winding machines) or also on machines with only one roller (so-called backup roller winding machines). It is not necessary to split the incoming web into strips in such machines. The cutting device described can also be used to cut a full width of a web.
