Description

Die Erfindung betrifft eine Vorrichtung zum kontinuierlichen Aufwickeln von Bahnen, vorzugsweise von Bahnen aus thermoplastischem Kunststoff, auf Wickelwellen oder Wickelhülsen zu Wickelrollen, mit die vorzugsweise mit einem Antrieb versehene Wickelwelle lagernden Armen, mit einer an die Wickelwelle oder Wickelhülse anstellbaren Andrückwalze, mit einem die Bahn bei einem Rollenwechsel durchtrennenden Trennmesser und mit einer Einrichtung zum Anwickeln des durch den Trennschnitt gebildeten neuen Bahnanfangs auf die Wickelwelle oder Wickelhülse.The invention relates to a device for the continuous winding of webs, preferably webs of thermoplastic material, on winding shafts or cores to winding rollers, with the preferably provided with a drive winding shaft arms, with an engageable with the winding shaft or winding roller pressure roller, with a the web at a roll change severing cutting knife and with a device for winding the formed by the separating cut new web start on the winding shaft or winding tube.

Ein besonderes Problem bei Vorrichtungen dieser Art besteht darin, den beim Rollenwechsel durch den Trennschnitt gebildeten neuen Bahnanfang auf eine neue Wickelwelle oder Wickelhülse anzuwickeln. Es ist bekannt, zum Anwickeln des Bahnanfangs der mit gleichbleibender Geschwindigkeit zugeführten Bahn die Wikkelhülse oder den Wickelkern mit einem klebrigen Auftrag zu versehen, an dem der Bahnanfang der auf Bahngeschwindigkeit beschleunigten Wickelwelle oder Wickelhülse haftet. Die Handhabung von mit klebrigen Aufträgen versehenen Wickelhülsen oder Wickelwellen ist jedoch aufwendig und schwierig. Weiterhin ist es bekannt, Bahnanfänge durch ringförmige Saugkanäle oder besondere ringförmige Führungskanäle mit Einführungskeilen um die Wickelhülse oder die Wickelwelle herumzulegen, bis die zweite Umschlingung den Bahnanfang auf der Wickelhülse festlegt. Auch derartige Einrichtungen sind verhältnismäßig kompliziert und aufwendig.A particular problem with devices of this type is to wind the new web beginning formed during the roll change by the separating cut on a new winding shaft or winding tube. It is known to provide the Wickkelhülse or the winding core with a sticky order to Anwickeln the web start of supplied at a constant speed web, where the web start of the accelerated at web speed winding shaft or winding tube adheres. However, the handling of tacky winding cores or winding shafts is complicated and difficult. Furthermore, it is known to lay web starts through annular suction channels or special annular guide channels with insertion wedges around the winding tube or the winding shaft until the second loop sets the beginning of the web on the winding tube. Such devices are relatively complicated and expensive.

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs angegebenen Art zu schaffen, die unabhängig von dem jeweiligen Durchmesser der Wickelwelle oder der Wickelhülse ein einfaches Anwickeln der beim Rollenwechsel durch Trennschnitte gebildeten Bahnanfänge auf den Wickelwellen oder Wickelhülsen ermöglicht.The object of the invention is to provide a device of the type described above, which allows independent of the respective diameter of the winding shaft or the winding tube a simple Anwickeln the web changes formed by separating cuts Bahnanfänge on the winding shafts or cores.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is solved by the features of patent claim 1.

Nach einer bevorzugten Ausführungsform ist vorgesehen, daß die Einrichtung zum Anwickeln aus einer den Bahnanfang mit einer elektrostatischen Ladung versehenden Aufladeelektrode besteht, die einem vorbestimmten Abstand zu der Bahn angeordnet und derart über Getriebemittel mit der verfahrbaren Andrückwalze gekoppelt ist, daß deren Abstand zu der Bahn unabhängig von dem Durchmesser der Wickelwelle oder Wickelhülse konstant bleibt.According to a preferred embodiment, it is provided that the means for Anwickeln from a web start providing the electrostatic charge charging electrode, which is arranged at a predetermined distance from the web and is coupled via transmission means with the movable pressure roller, that their distance from the web independently remains constant from the diameter of the winding shaft or winding tube.

Aus der US-PS 4 852 820 ist es bekannt, den durch einen Trennschnitt einer kontinuierlich zugeführten Folienbahn gebildeten Bahnanfang dadurch in anhaftenden Kontakt mit einem Wickelkern oder einer Wickelhülse zu bringen, daß der Bahnanfang durch eine Elektrode mit einer elektrostatischen Aufladung versehen wird, die diese Anhaftung bewirkt. Vor dem Trennschnitt kann jedoch dem durch den Trennschnitt gebildeten Bahnanfang nur dann in optimaler Weise die erforderliche elektrostatische Aufladung erteilt werden, wenn die Aufladeelektrode den richtigen vorbestimmten Abstand zu der Bahn aufweist. Auf Wickelvorrichtungen werden üblicherweise Bahnen und vorzugsweise Folienbahnen auf Wickelhülsen oder Wickelkerne unterschiedlicher Durchmesser aufgewickelt, so daß die Einhaltung des richtigen vorbestimmten Abstands der Aufladeelektrode zu der Bahn problematisch ist. Bei der erfindungsgemäßen Vorrichtung stellt sich die Aufladeelektrode immer dadurch auf den richtigen vorbestimmten Abstand zu der Bahn ein, daß sie durch Nachführungseinrichtungen in der Weise nachgeführt wird, daß der Abstand zu der Bahn unabhängig von dem Durchmesser der Wickelwelle oder Wickelhülse kon-, stant bleibt.From US Pat. No. 4,852,820 it is known to bring the web beginning formed by a separating cut of a continuously fed film web into adhesive contact with a winding core or a winding tube in such a way that the web start is provided with an electrostatic charge by an electrode which contains same Attachment causes. However, before the separation cut, the web start formed by the separation cut can be given the required electrostatic charge optimally only when the charging electrode has the correct predetermined distance from the web. On winding devices usually webs and preferably film webs are wound on winding tubes or hubs of different diameters, so that the maintenance of the correct predetermined distance of the charging electrode to the web is problematic. In the apparatus according to the invention, the charging electrode always adjusts itself to the correct predetermined distance from the web, that it is tracked by tracking devices in such a way that the distance to the web remains constant irrespective of the diameter of the winding shaft or winding tube.

Nach einer bevorzugten Ausführungsform ist vorgesehen, daß die Andrückwalze in einem in einem Maschinengestell verfahrbaren Schlitten gelagert und die sich über die Breite der Bahn erstreckende Aufladeelektrode zwischen den Armen von zweiarmigen Hebeln, die an Seitenteilen oder Schlitten schwenkbar gelagert sind, gehalten ist und daß die anderen Arme zweiarmigen Hebel Gleitsteine oder Rollen tragen, die in Führungen der Seitenteile des Gestells laufen, die entsprechend der erforderlichen Nachführungsbewegung der Aufladeelektrode ausgelegt sind.According to a preferred embodiment, it is provided that the pressure roller mounted in a carriage movable in a machine frame and extending across the width of the web charging electrode between the arms of two-armed levers which are pivotally mounted on side parts or carriage, is held and that the other Arm two-armed lever wear sliding blocks or rollers that run in guides of the side parts of the frame, which are designed according to the required tracking movement of the charging electrode.

Zweckmäßigerweise ist der Schlitten in oder parallel zu einer Ebene verfahrbar, die durch die Achsen der Wickelwelle und der Andrückwalze aufgespannt ist.Conveniently, the carriage is movable in or parallel to a plane which is spanned by the axes of the winding shaft and the pressure roller.

Der Schlitten kann in dem Maschinengestell durch einen Getriebemotor verfahrbar sein, dessen Ritzel mit einer Zahnstange des Schlittens kämmt. Die Steuerung des Getriebemotors kann durch einen Rechner erfolgen.The carriage can be moved in the machine frame by a geared motor whose pinion meshes with a rack of the carriage. The control of the geared motor can be done by a computer.

Zweckmäßigerweise ist das Trennmesser an dem die Aufladeelektrode tragenden Träger gehalten. Nach einer einfachen Ausführungsform ist vorgesehen, daß das Trennmesser von einem kolbenstangenlosen Pneumatikzylinder quer zu der Bahn bewegbar ist.The separating knife is expediently held on the carrier carrying the charging electrode. According to a simple embodiment it is provided that the separating knife is movable transversely to the web by a rodless pneumatic cylinder.

Um ein Links-Rechts Anwickeln zu ermöglichen, sind nach einer bevorzugten Ausführungsform spiegelbildlich zu der Ebene, die durch die Achsen der Wickelwelle und der Andrückrolle aufgespannt ist, eine zweite nachführbare Aufladeelektrode mit Trennmesser angeordnet.In order to allow a left-right Anwickeln, according to a preferred embodiment, a mirror image to the mirrored plane, which is spanned by the axes of the winding shaft and the pressure roller, a second trackable charging electrode with separating knife.

Aus Fig. 1 ist ein hinteres plattenförmiges Seitenteil 1 ersichtlich, das Teil eines Maschinengestells ist. Das vordere Seitenteil ist entfernt, um die zwischen den Seitenteilen angeordneten Einrichtungen besser sichtbar zu machen.From Fig. 1, a rear plate-shaped side part 1 can be seen, which is part of a machine frame. The front side panel is removed to better visualize the devices located between the side panels.

Zwischen den Seitenteilen 1 ist ein Schlitten horizontal verfahrbar geführt. Von dem Schlitten ist ebenfalls nur die hintere Seitenwand 2 dargestellt, da die vordere Seitenwand wiederum aus Gründen der besseren Darstellung entfernt ist. Die Seitenwände 1 des Schlittens sind durch nicht dargestellte Quertraversen miteinander verbunden. Die Seitenwände 2 sind in gestrichelt dargestellten Führungen 3 der Seitenteile 1 verschieblich geführt. An ihrer oberen Seitenkante ist mindestens die Seitenwand 2 mit einer Zahnstange 4 versehen, die mit dem Ritzel 5 eines Getriebemotors 6 kämmt, der zum Verfahren des Schlitten mit den Seitenwänden 2 von der elektronischen Maschinensteuerung gesteuert ist.Between the side members 1, a carriage is guided horizontally movable. Of the carriage also only the rear side wall 2 is shown, since the front side wall is again removed for better illustration. The side walls 1 of the carriage are interconnected by crossbeams, not shown. The side walls 2 are guided in dashed lines guides 3 of the side parts 1 slidably. At its upper side edge at least the side wall 2 is provided with a rack 4 which meshes with the pinion 5 of a geared motor 6, which is controlled for moving the carriage with the side walls 2 of the electronic machine control.

Auf einer zwischen den Seitenwänden 2 gelagerten Welle 7 sind beidseits zweiarmige Hebel 8 schwenkbar gelagert, deren in Richtung der Wickelhülse 9 weisenden Arme 10 die sich über die Breite der Bahn 11 erstreckende Aufladeelektrode 12 tragen. Die inneren Arme 13 des zweiarmigen Hebels 8 sind mit Achszapfen 14 versehen, auf denen Rollen 15 gelagert sind, die in aus Langlöchem bestehenden Führungen 16 der Seitenteile 1 des Gestells geführt sind. Die Führungen 16 bestehen aus einem schräg verlaufenden Abschnitt 17 und einen an diesen anschließenden parallel zu der Führung 3 verlaufenden Abschnitt 18.On a shaft 7 mounted between the side walls 2, two-armed levers 8 are pivotally mounted on both sides, their arms 10 pointing in the direction of the winding sleeve 9 carrying the charging electrode 12 extending over the width of the web 11. The inner arms 13 of the two-armed lever 8 are provided with journals 14, on which rollers 15 are mounted, which are guided in existing from elongated guides 16 of the side parts 1 of the frame. The guides 16 exist from an obliquely extending portion 17 and a subsequent thereto parallel to the guide 3 extending portion 18th

An den nach außen weisenden Armen 10 der zweiarmigen Hebel 8 ist nicht nur die Elektrode 12, sondem zusätzlich auch eine Lineareinheit, beispielsweise ein kolbenstangenloser Pneumatikzylinder, befestigt, der zum Zwecke des Durchtrennens der Bahn 11 ein Trennmesser 19 über die Breite der Bahn 11 verfährt.On the outwardly facing arms 10 of the two-armed lever 8 not only the electrode 12, but in addition also a linear unit, such as a rodless pneumatic cylinder, attached, for the purpose of severing the web 11 a separating knife 19 moves across the width of the web 11.

Beidseits der Welle 7 sind auf den Innenseiten der Seitenwände 2 des Schlittens Schwingen 20 schwenkbar gelagert, die durch Pneumatikzylinder 23 verschwenkbar sind, deren Kolbenstangen 21 auf Zapfen 22 der Schwingen 20 schwenkbar gelagert sind. Die Zylinder 23 sind auf Zapfen 24 der Seitenwände 2 der Schlitten schwenkbar gelagert.On both sides of the shaft 7 rockers 20 are pivotally mounted on the inner sides of the side walls 2 of the carriage, which are pivotable by pneumatic cylinders 23, the piston rods 21 are pivotally mounted on pins 22 of the rockers 20. The cylinders 23 are pivotally mounted on pins 24 of the side walls 2 of the carriage.

Unterhalb des Pneumatikzylinders 23 ist parallel zu diesem Zugfedem 25 angeordnet, deren Enden auf Zapfen 26 der Schwinge 20 und Zapfen 27 der Seitenwand 2 eingehängt sind.Below the pneumatic cylinder 23 is arranged parallel to this Zugfedem 25, whose ends are mounted on pins 26 of the rocker 20 and pin 27 of the side wall 2.

Die Schwingen 20 tragen oberhalb des Pneumatikzylinders 23 Achszapfen 30, auf denen Koppelglieder 31 gelagert sind. Die Koppelglieder 31 sind an ihren hinteren Enden gelenkig in den Gelenkpunkten 33 mit Lenkern 32 verbunden, deren oberen Enden auf Achszapfen 34 der Seitenwände 2 schwenkbar gelagert sind. Die Koppelglieder 31 überragen die Schwingen 20 in Richtung auf die Wickelhülse 9. Zwischen den freien Enden der Koppelstangen 31 ist die Andrückwalze 38 gelagert.The rockers 20 carry above the pneumatic cylinder 23 journals 30 on which coupling members 31 are mounted. The coupling members 31 are hingedly connected at their rear ends in the hinge points 33 with arms 32, the upper ends of which are pivotally mounted on journals 34 of the side walls 2. The coupling members 31 project beyond the rockers 20 in the direction of the winding tube 9. Between the free ends of the coupling rods 31, the pressure roller 38 is mounted.

Die Elektrode 12 kann aus einer Reihe von Nadeln bestehen und ist seitlich von Leisten eingefaßt, die diese schützend abdecken.The electrode 12 may consist of a series of needles and is laterally bordered by strips, which cover this protective.

Die Anordnung des Messers 19 mit Zylinder auf dem Träger der Elektroden 12 führt bei der Aktivierung des Trennmessers zu einem Durchtrennen dicht oberhalb des Walzenspalts zwischen der Wickelhülse 9 und der Andrückwalze 38, so daß ein Bahnanfang mit kurzer Fahne entsteht.The arrangement of the knife 19 with cylinder on the support of the electrodes 12 results in the activation of the cutting blade to severing just above the nip between the winding tube 9 and the pressure roller 38, so that a web start with a short flag is formed.

Die Bahn 11 läuft in Richtung des Pfeils A und wird der Andrückwalze 38 durch eine Leitwalze 39 zugeführt, die beispielsweise zwischen den Seitenwänden 2 des Schlittens gelagert sein kann.The web 11 runs in the direction of the arrow A and is supplied to the pressure roller 38 by a guide roller 39, which may for example be mounted between the side walls 2 of the carriage.

Die zweiarmigen Hebel 8 mit Elektroden 12 und Schneidmessem 19 sowie die Führungen 16 für die Rollen 15 der inneren Arme der zweiarmigen Hebel 8 sind spiegelbildlich zu einer Mittelebene 40 angeordnet, die durch die Achsen der Wickelhülse 9 und der Andrückwalze 38 verläuft. Auf diese Weise ist eine einfache Umstellung der Wickelvorrichtung auf Links-Rechts-Wickeln möglich.The two-armed lever 8 with electrodes 12 and Schneidmessem 19 and the guides 16 for the rollers 15 of the inner arms of the two-armed lever 8 are arranged in mirror image to a central plane 40 which extends through the axes of the winding tube 9 and the pressure roller 38.
