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 bzw. die sich bildende Wickelrolle anstellbaren, in einem Maschinengestell gelagerten Andrückwalze und mit einem die Bahn beim Rollenwechsel durchtrennenden Trennmesser. Eine solche Vorrichtung ist in der US 61 09 559, die als nächster Stand der Technik angesehen wird, offenbart.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, preferably with a drive provided winding shaft overlapping arms, with an engagable to the winding shaft or winding tube or the forming winding roll , In a machine frame mounted pressure roller and with a web when reel splitting severing cutter. Such a device is disclosed in US 61 09 559, which is considered as the closest prior art.

Bei Wickelvorrichtungen dieser Art wird die Andrückwalze gegen die Wickelhülse bzw. die sich bildende Wickelrolle durch eine Antriebseinrichtung angedrückt, um eine festgewickelte Wickelrolle ohne Lufteinschlüsse zwischen den einzelnen aufgewickelten Lagen zu erhalten. Es sind Vorrichtungen der eingangs angegebenen Art bekannt, bei denen die Andrückwalze auf einem Schlitten gelagert ist, der mit einem die Andrückwalze verfahrenden und gegen die Wickelhülse oder die sich bildende Wickelrolle andrückenden Antrieb versehen ist. Der in Führungen des Maschinengestells verschiebliche Schütten läßt sich nur gegen erhebliche unvermeidbare Reibungskräfte verfahren, er bildet auch mit der auf diesem gelagerten Andrückwalze erhebliche Massen, die beim Verfahren des Schlittens bewegt werden müssen.In winding devices of this type, the pressure roller is pressed against the winding tube or the forming winding roll by a drive device to obtain a tight wound reel without air pockets between the individual wound layers. There are devices of the type described above are known in which the pressure roller is mounted on a carriage, which is provided with a moving the pressure roller and provided against the winding tube or the winding roller forming drive. The sliding in guides of the machine frame pouring can be moved only against considerable unavoidable frictional forces, it also forms with the bearing on this pressure roller significant masses that must be moved while moving the carriage.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs angegebenen Art zu schaffen, die ein reibungsarmes Anstellen der Andrückwalze an die Wickelhülse bzw. die sich bildende Wickelrolle ermöglicht.The object of the invention is therefore to provide a device of the type described above, which allows a low-friction hiring the pressure roller to the winding tube or the forming winding roll.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Andrückwalze zumindest an einer Koppelstange gelagert ist, die gelenkig mit zwei Lenkern verbunden ist, deren anderen Enden im Maschinengestell schwenkbargelagert sind, und daß die Koppelstange oder einer der Lenker mit einer Antriebseinrichtung versehen ist.According to the invention this object is achieved in that the pressure roller is mounted at least on a coupling rod which is pivotally connected to two links whose other ends are pivotally mounted in the machine frame, and that the coupling rod or one of the links is provided with a drive means.

Zweckmäßigerweise ist die Andrückwalze zwischen zwei Koppelstangen gelagert, die jeweils gelenkig mit zwei Lenkern verbunden sind, deren anderen Enden in dem Maschinengestell schwenkbar gelagert sind.Conveniently, the pressure roller is mounted between two coupling rods, which are each pivotally connected to two arms whose other ends are pivotally mounted in the machine frame.

Die erfindungsgemäß vorgesehene Koppelstange mit zwei Lenkern bildet ein Vier-Gelenk-Tragsystem, das das Gewicht der Andrückwalze in günstiger Weise aufnimmt. Die erfindungsgemäße Vorrichtung zeichnet sich somit dadurch aus, daß die Andrückwalze reibungsarm zwischen Koppelstangen von Vier-Gelenk-Systemen gelagert ist. In der erfindungsgemäßen Vorrichtung läßt sich die Andrückwalze feinfühlig durch ihre Antriebseinrichtung an die Wickelhülse bzw. die sich bildende Wickelrolle anstellen, da keine größeren Reibungskräfte zu überwinden sind. Da die Andrückwalze nicht auf einem Schlitten gelagert ist, sind die zu bewegenden Massen verringert. Die Andrückwalze wird durch ihren Antrieb nur in horizontaler Richtung bewegt, so daß der Einfluß der Masse auf die Andrückkraft vernachlässigbar ist.The inventively provided coupling rod with two arms forms a four-joint support system that receives the weight of the pressure roller in a favorable manner. The device according to the invention is thus characterized by the fact that the pressure roller is mounted with low friction between coupling rods of four-joint systems. In the apparatus according to the invention, the pressure roller can sensitively by their drive device to the winding tube or the forming winding roll hire, as no major frictional forces are overcome. Since the pressure roller is not mounted on a carriage, the masses to be moved are reduced. The pressure roller is moved by its drive only in the horizontal direction, so that the influence of the mass on the pressing force is negligible.

Zweckmäßigerweise besteht die Antriebseinrichtung aus mindestens einem Pneumatikzylinder.The drive device expediently consists of at least one pneumatic cylinder.

Zweckmäßigerweise ist die Andrückwalze zwischen die einen Lenker in Richtung auf die Wickelrolle überragenden Abschnitten der Koppelstange gelagert. Nach einer besonders bevorzugten Ausführungsform ist vorgesehen, daß die Lenker aus einem in Richtung auf die Wickelhülse oder Wickelrolle gesehenen vorderen Lenker bestehen, der länger ist als der hintere. Ist die Wickelrolle zwischen den die beiden vorderen Lenker überragenden Abschnitten der Koppelstangen im Abstand von den vorderen Lenkern gelagert, verschwenken die hinteren kürzeren Lenker aufgrund ihres kleineren Schwenkradius die Koppelstangen um die Gelenke an den vorderen Lenkern in einer Weise, daß der anhebenden Wirkung des Vier-Gelenk-Systems eine Schwenkbewegung der Koppelstange überlagert wird, so daß die Andrückwalze bei ihrer Verschiebung in Richtung auf die Wickelhülse bzw. Wickelrolle eine lineare Bewegung ausführt.Conveniently, the pressure roller is mounted between the a handlebar in the direction of the winding roll superior portions of the coupling rod. According to a particularly preferred embodiment, it is provided that the links consist of a seen in the direction of the winding tube or winding roll front link, which is longer than the rear. If the winding roller between the two front links protruding portions of the coupling rods spaced from the front links, pivot the rear shorter links because of their smaller pivot radius, the coupling rods around the joints on the front links in such a way that the lifting effect of the four Joint system is a pivoting movement of the coupling rod is superimposed, so that the pressure roller performs a linear movement during its displacement in the direction of the winding tube or winding roll.

Diese angenäherte Geradführung läßt sich noch dadurch verbessern, daß die hinteren, kürzeren Lenker ausgehend von ihren Schwenklagerungen an dem Maschinengestell spitzwinkelig zu den längeren vorderen Lenkern verlaufen.This approximate linear guide can be further improved by the fact that the rear shorter handlebars extend from their pivotal mounting on the machine frame at an acute angle to the longer front arms.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß die Lenker an einem im Maschinengestell verfahrbaren Schlitten gelagert sind. Die Schlitten sind mit einem gesteuerten Antrieb versehen, der diesen verfährt, wenn der Weg der angenäherten Geradführung des aus den Lenkern und Koppelstangen bestehenden Systems erschöpft ist.In a further embodiment of the invention it is provided that the handlebars are mounted on a carriage movable in the machine frame. The carriages are provided with a controlled drive which moves them when the path of the approximate straight line of the system consisting of the links and connecting rods is exhausted.

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 Langlöchern 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 slots from guides 16 of the side parts 1 of the frame. The guides 16 consist of 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, sondern zusätzlich auch eine Lineareinheit, beispielsweise ein kolbenstangenloser Pneumatikzylinder, befestigt, der zum Zwecke des Durchtrennens der Bahn 11 ein Trennmesser 19 Ober die Breite der Bahn 11 verfährt.On the outwardly facing arms 10 of the two-armed lever 8 is not only the electrode 12, but also a linear unit, such as a rodless Pneumatic cylinder, fixed, 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 Zugfedern 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 tension springs 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 dem kolbenstangenlosen Pneumatikzylinder 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 the rodless pneumatic cylinder on the support of the electrodes 12 leads to 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.

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 stored between the side walls 2 of the carriage.

Die zweiarmigen Hebel 8 mit Elektroden 12 und Schneidmessern 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 cutting blades 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 median plane 40 which extends through the axes of the winding tube 9 and the pressure roller 38. In this way, a simple conversion of the winding device to left-right winding is possible.

Aus Fig. 2 ist das aus der Fig. 1 zum Zwecke der übersichtlicheren Darstellung herausgezogene aus den Lenkern und der Koppelstange bestehende Vier-GelenkSystem zur annähernden Geradführung der Andrückwalze 38 ersichtlich. Die Lenker bildenden Schwingen 20 jeder Seite sind an der Schwenkwelle 7 befestigt bzw. an diese angeklemmt, die in der aus Fig. 3 ersichtlichen Weise zwischen den Seitenwänden 2 des in Führungen 3 der Seitenteile 1 verschieblichen Schlittens gelagert sind. Die Lenker 32 sind auf den Achszapfen 34 schwenkbar gelagert, die in der aus Fig. 3 ersichtlichen Weise fest mit den Seitenwänden 2 verbunden sind. An den Schwingen 20 sind in den Gelenken 30 und an den Lenkern 32 sind in den Gelenken 33 die Koppelglieder oder Koppelstangen 31 angelenkt. Die Koppeistangen 31 überragen die Schwingen 20 um Abschnitte 40 vorbestimmter Länge, zwischen denen die Andrückwalze 38 gelagert ist.From Fig. 2, the drawn out of Fig. 1 for the sake of clarity of illustration consisting of the links and the coupling rod four-joint system for approximate linear guidance of the pressure roller 38 can be seen. The handlebars forming rockers 20 each side are attached to the pivot shaft 7 and clamped to this, which are stored in the manner shown in FIG. 3 way between the side walls 2 of the sliding in guides 3 of the side parts 1 slide. The links 32 are pivotally mounted on the axle journal 34, which are firmly connected in the manner shown in FIG. 3 manner with the side walls 2. On the rockers 20 are in the joints 30 and the links 32 in the joints 33, the coupling links or coupling rods 31 are hinged. The Koppeistangen 31 extend beyond the wings 20 to portions 40 of predetermined length, between which the pressure roller 38 is mounted.

Der Lenker 32 ist kürzer als die Schwinge 20 zwischen ihren Gelenken 7 und 30. Im dargestellten Ausführungsbeispiel ist der Lenker 32 ausgehend von seinem oberen Lager 34 spitzwinkelig in Richtung auf die Schwinge 20 geneigt. Die unterschiedlichen Längen der Schwingen 20 und der Lenker 32 sowie die Abstände der Gelenke 30 und 33 auf den Koppelstangen 31 und die Längen der Koppelstangenabschnitte 40 zwischen den Lagern für die Andrückwalze 38 und den Lagern 30 auf den Schwingen 20 sind so aufeinander abgestimmt, daß bei einem Verschwenken der Koppelstangen zwischen der in vollen Linien dargestellten Stellung der Andrückwalze 38 in Fig. 2, in der die Koppelstangen in Richtung auf die Wickelhülse verschoben sind, und der strichpunktiert dargestellten zurückgezogenen Stellung die Bewegung der Andrückwalze annähernd linear in horizontaler Richtung erfolgt.The link 32 is shorter than the rocker 20 between their joints 7 and 30. In the illustrated embodiment, the handlebar 32 is inclined starting from its upper bearing 34 at an acute angle in the direction of the rocker 20. The different lengths of the wings 20 and the handlebar 32 and the distances between the joints 30 and 33 on the coupling rods 31 and the lengths of the coupling rod portions 40 between the bearings for the pressure roller 38 and the bearings 30 on the rockers 20 are coordinated so that at a pivoting of the coupling rods between the position shown in solid lines of the pressure roller 38 in Fig. 2, in which the coupling rods are displaced in the direction of the winding tube, and the dot-dashed position shown retracted the movement of the pressure roller is approximately linear in the horizontal direction.

Die Schwingen 20 überragen die Koppelstangen 31 um Abschnitte 41 vorbestimmter Länge nach unten. An jedem Abschnitt ist unterhalb der Koppelstange 31 ein Lagerzapfen 22 vorgesehen, auf den die Kolbenstange 21 des Pneumatikzylinders 23 gelagert ist, der seinerseits auf dem Zapfen 24 schwenkbar gelagert ist, der fest mit der Seitenwand 2 verbunden ist.The wings 20 project beyond the coupling rods 31 by sections 41 of predetermined length down. At each section, a bearing pin 22 is provided below the coupling rod 31, on which the piston rod 21 of the pneumatic cylinder 23 is mounted, which in turn is pivotally mounted on the pin 24 which is fixedly connected to the side wall 2.

Unterhalb des Pneumatikzylinders 23 ist zwischen den Zapfen 26 der Abschnitte 41 der Schwingen 20 und den an den Seitenwänden 2 vorgesehenen Zapfen 27 die Zugfedern 25 gespannt, die dazu dienen, den Stellbereich der Anpreßkraft zu vergrößern, die von den Pneumatikzylindern 23 auf die Schwingen 20 ausgeübt wird.Below the pneumatic cylinder 23, the tension springs 25 are tensioned between the pin 26 of the portions 41 of the rockers 20 and provided on the side walls 2 pin 27, which serve to increase the adjustment range of the pressing force exerted by the pneumatic cylinders 23 on the wings 20 becomes.
