VERFAHRENUND VORRICHTUNG ZURHERSTELLUNG VONWICKELNAUSEINERGROSSEN ZAHLFLÄCHIGER METHOD AND DEVICE FOR THE PRODUCTION OF NON-LARGE NUMBER OF AREAS
GEGENSTÄNDEOBJECTS
Die Erfindung betrifft ein Verfahren und eine Vorrichtung nach den Oberbegriffen der entsprechenden, unabhängigen Patentansprüche. Verfahren und Vorrichtung dienen zur Herstellung von Wickeln aus einer grossen Zahl von flächigen Gegenständen, insbesondere von Druckprodukten.The invention relates to a method and a device according to the preambles of the corresponding independent claims. The method and device are used to produce coils from a large number of flat objects, in particular printed products.
Druckprodukte (z.B. Zwischenprodukte ab Druckmaschine) werden für Transport und Zwischenlagerung vielfach in geschuppter Formation zu Wickeln aufgewickelt. Auch für andere flächige, mindestens beschränkt flexible Gegenstände, beispielsweise für textile Gegenstände, können derartige Wickel vorteilhafte Transport- und/oder Lagerformationen darstellen.Printed products (e.g. intermediate products from the printing machine) are often wound up in coils for transport and intermediate storage in shingled formation. Such coils can also represent advantageous transport and / or storage formations for other flat, at least limitedly flexible objects, for example for textile objects.
Die genannten Wickel weisen einen im wesentlichen zylindrischen Wickelkern auf und mindestens ein Wickelband, wobei das Wickelband in einem gespannten Zustand zusammen mit der geschuppten Formation der flächigen Gegenstände auf den Wickelkern gewickelt wird und diesen zusammenhält. Das Ende des Wickelbandes kann um den fertigen Wickel geschlossen oder in einer andern geeigneten Weise fixiert werden. Das Wickelband hat üblicherweise eine Breite, die bedeutend kleiner ist als die Breite der aufgewickelten Gegenstände. Druckprodukte werden meist in Schuppenformation aufgewickelt; es ist aber durchaus denkbar, diese auch hintereinander angeordnet, das heisst also einander nicht überlappend aufzuwickeln.The mentioned windings have an essentially cylindrical winding core and at least one winding band, the winding band being wound in a tensioned state together with the flaky formation of the flat objects on the winding core and holding it together. The end of the winding tape can be closed around the finished winding or fixed in some other suitable way. The wrapping tape usually has a width that is significantly smaller than the width of the wound objects. Print products are mostly in Scale formation wound up; however, it is also conceivable to arrange them one behind the other, that is, not to wind them overlapping each other.
In der Druckereibranche übliche, derartige Wickel haben Durchmesser bis zu über zwei Metern und können über eine Tonne wiegen. Die aufgewickelten Produkte sind beispielsweise ca. 30 bis 50 cm breit und derart geschuppt, dass der Produkteabstand etwa 10 cm oder weniger beträgt. Übliche Wickelbänder sind etwa 5 bis 10 cm breit.Coils of this type that are common in the printing industry have diameters of up to over two meters and can weigh over a ton. The wound products are, for example, about 30 to 50 cm wide and scaled in such a way that the product distance is about 10 cm or less. Usual winding tapes are about 5 to 10 cm wide.
Zur Herstellung der Wickel werden Wickelvorrichtungen eingesetzt, deren wesentliche Bestandteile die folgenden sind: Mittel zum Halten eines Wickelkerns (üblicherweise mit horizontaler Wickelachse), Mittel zur Zuführung der Schuppenforma- tion der flächigen Gegenstände zu einem Wickelpunkt an der Peripherie des Wickelkerns bzw. eines entstehenden Wickels, Mittel zur geordneten Zuführung des gespannten Wickelbandes zum Wickelpunkt und ein Antrieb für eine Rotation des Wickelkerns bzw. des entstehenden Wickels mit einer im wesentlichen konstanten Umfangsgeschwindigkeit. Derartige Wickelvorrichtungen sind beispielsweise be- schrieben in den Publikationen EP-0243838 (oder US-4775111) oder EP-0281790 (oder US-4898336).Winding devices are used to produce the windings, the essential components of which are the following: means for holding a winding core (usually with a horizontal winding axis), means for feeding the scale formation of the flat objects to a winding point on the periphery of the winding core or an emerging winding , Means for the orderly supply of the tensioned winding tape to the winding point and a drive for a rotation of the winding core or the resulting winding with an essentially constant peripheral speed. Such winding devices are described, for example, in the publications EP-0243838 (or US-4775111) or EP-0281790 (or US-4898336).
Die Mittel zur Zuführung der Schuppenformation weisen beispielsweise ein Paar von Förderbändern auf, die im wesentlichen tangential zum Wickelpunkt (z.B. Bereich des unteren Scheitelpunktes des Wickelkerns, bzw. des entstehenden Wickels) führen und auf denen die geschuppte Formation der Gegenstände lose aufliegend zugefördert wird. Das Wickelband wird beispielsweise zwischen den beiden Zuförderbän- dern zugeführt, derart, dass die Schuppenformation zwischen Wickelband und entstehendem Wickel in den Wickelpunkt geführt wird. Im Wickelpunkt, in dem die zugeführten Gegenstände nacheinander in den Wickel aufgenommen werden, über- nimmt das gespannte Wickelband die radiale Pressung der Gegenstände im Wickel, gegebenenfalls etwas unterstützt durch eine entsprechende, beispielsweise vom Zu- führungsmittel ausgeübte Presskraft im Bereiche des Wickelpunktes.The means for feeding the scale formation have, for example, a pair of conveyor belts which lead essentially tangentially to the winding point (for example the area of the lower vertex of the winding core or the resulting winding) and on which the flaky formation of the objects is conveyed in a loosely lying manner. The winding tape is fed, for example, between the two feed conveyor belts in such a way that the scale formation between the winding tape and the resulting winding is guided into the winding point. At the winding point at which the supplied objects are taken up one after the other in the winding, the tensioned winding band takes over the radial pressing of the objects in the winding, if necessary, somewhat supported by a corresponding pressing force, for example exerted by the feed means, in the area of the winding point.
Zur Anpassung der Wickelvorrichtung an den wachsenden Durchmesser des entstehenden Wickels wird entweder das Zuführungsmittel entsprechend verschwenkt oder die Achse des Wickelkerns wird entsprechend verschoben. Der Antrieb zum Wickeln greift beispielsweise am Wickelkern an oder an der Peripherie des entstehenden Wickels im Bereiche des Wickelbandes.To adapt the winding device to the growing diameter of the resulting winding, either the feed means is pivoted accordingly or the axis of the winding core is shifted accordingly. The drive for winding engages, for example, on the winding core or on the periphery of the resulting winding in the area of the winding tape.
Zur Wiedererstrellung der geschuppten Formation aus einem Wickel, das heisst zum Abwickeln, wird die Wickelvorrichtung im wesentlichen gegenläufig zum Wickel- Vorgang betrieben, wobei die Wickelrotation beispielsweise durch aktives Abziehen der Wickelbandes erzeugt wird.In order to recreate the shingled formation from a winding, that is to say for unwinding, the winding device is operated essentially in the opposite direction to the winding process, the winding rotation being generated, for example, by actively pulling off the winding tape.
Es zeigt sich, dass die oben beschriebenen Wickel und deren Herstellung und Auflösung um so problemloser ist, je kleiner und regelmässiger die Dicke der Gegenstände ist, je weniger kompressibel die Gegenstände sind und je weniger eng die Schuppung ist. In Wickeln von relativ dicken, kompressiblen und/oder eng geschuppten Druckprodukten erzeugt das Wickelband eine Einschnürung derart, dass die Produkte sich mindestens in den äusseren Lagen des entstehenden Wickels gegen aussen um das Band biegen und der Wickel im Bereich seiner Stirnseiten einen grösseren Umfang aufweist als im zentralen Bereich, wo er vom Wickelband zusammengehalten wird. Handelt es sich zusätzlich um Produkte die auf der einen Seite dicker sind als auf der anderen Seite, kommt zur Einschnürung noch eine Asymmetrie derart, dass die beiden Stirnseiten des Wickels verschiedene Durchmesser aufweisen. Die genannten Phänomene können Probleme erzeugen dadurch, dass sie den Wickel destabilisieren, dadurch, dass die Gegenstände im Wickel Schaden nehmen oder wegen der Verformung in einer aus dem Wickel wieder erstellten Schuppenformation nicht stabil liegen und/oder dadurch, dass es schwierig wird, die Umfangsgeschwin- digkeit eines entstehenden oder abzubauenden Wickels an die Geschwindigkeit einer Zuführung oder Wegführung der Schuppenformation anzupassen. Die genannten Probleme sind in der Druckereibranche insbesondere bekannt für das Wickeln von relativ dicken, zweimal gefalteten Druckprodukten, deren zweiter Falz im Wickel parallel zur Wickelachse ausgerichtet ist, derart, dass auf der einen Stirnseite des Wickels ungefaltete Produktekanten (kleinere Dicke) und auf der anderen Stirnseite des Wickels der erste Falz der Produkte, also gefaltete Produktekanten (grössere Dicke), aufeinander liegen. Derartige Produkte sind beispielsweise zweifach gefaltete Zeitungen oder Sektionen von Zeitungen.It turns out that the smaller and more regular the thickness of the objects, the less compressible the objects and the less tight the scaling, the less problematic is the winding described above and its production and dissolution. In the winding of relatively thick, compressible and / or closely scaled printed products, the winding tape constricts in such a way that the products bend outwards around the tape at least in the outer layers of the resulting roll and the roll has a larger circumference in the area of its end faces than in the central area, where it is held together by the winding tape. If there are additional products that are thicker on one side than on the other side, there is an asymmetry in the constriction in such a way that the two end faces of the roll have different diameters. The phenomena mentioned can create problems by destabilizing the winding, by the objects in the winding being damaged or not being stable due to the deformation in a scale formation created from the winding and / or by the circumferential speed becoming difficult - Adapt the speed of a emerging or to be dismantled roll to the speed of feeding or leading away the scale formation. The problems mentioned are particularly known in the printing industry for the winding of relatively thick, twice-folded printed products, the second fold of which is aligned parallel to the winding axis in such a way that unfolded product edges (smaller thickness) on one end of the roll and on the other The first fold of the products, i.e. folded product edges (greater thickness), lie on top of one another on the end of the roll. Such products are, for example, double-folded newspapers or sections of newspapers.
Die Erfindung stellt sich nun die Aufgabe, Verfahren und Vorrichtung zur Herstel- lung von Wickeln aus einer grossen Zahl von flächigen Gegenständen derart zu verbessern, dass die oben genannten Probleme weniger auftreten, dass also auch relativ dicke, relativ kompressible und/oder unregelmässig, insbesondere einseitig dicke Gegenstände mit besseren Resultaten zu Wickeln aufgewickelt werden können, auch wenn sie als enge Schuppenformation, das heisst mit kleinen Abständen zwischen benachbarten Gegenständen aufgewickelt werden sollen.The object of the invention is to improve the method and device for producing coils from a large number of flat objects in such a way that the above-mentioned problems occur less, that is to say also relatively thick, relatively compressible and / or irregularly, in particular objects that are thick on one side can be wound into coils with better results, even if they are to be wound as a narrow scale formation, that is to say with small distances between adjacent objects.
Diese Aufgabe wird gelöst durch das Verfahren und die Vorrichtung, wie sie in den unabhängigen Patentansprüchen definiert sind.This object is achieved by the method and the device as defined in the independent patent claims.
Gemäss Erfindung werden die flächigen Gegenstände in einem entstehenden Wickel während des Wickelvorganges nicht nur durch das gespannte Wickelband (zentraler Bereich) und ihre eigene Steifheit (seitliche Bereiche) gegen den Wickelkern ge- presst, sondern sie werden vorübergehend einer zusätzlichen Presskraft ausgesetzt. Die zusätzliche Presskraft wirkt während dem Wickelvorgang örtlich in einem vom Wickelpunkt beabstandeten, im wesentlichen stationären Pressbereich auf die Peripherie des entstehenden Wickels und hat eine Komponente in Richtung des Wickel- radius. Die zusätzliche Presskraft kann beispielsweise über die ganze Wickelbreite ausgeübt werden, beschränkt sich aber vorteilhafterweise auf Peripheriebereiche neben dem Wickelband bis zur Kante der Wickelstirnflächen. Vorteilhafterweise befindet sich der Pressbereich in Wickelrichtung hinter dem Wickelpunkt, derart, dass durch die zusätzliche Presskraft gepresste Gegenstände bald nachher in den Wickel- punkt gelangen und von einer weiteren Wickellage gedeckt wird.According to the invention, the flat objects in an emerging winding during the winding process are protected against the winding core not only by the tensioned winding band (central area) and their own rigidity (lateral areas) presses, but they are temporarily subjected to an additional pressing force. The additional pressing force acts locally during the winding process in a substantially stationary pressing area spaced from the winding point on the periphery of the winding being formed and has a component in the direction of the winding radius. The additional pressing force can be exerted, for example, over the entire winding width, but is advantageously limited to peripheral areas next to the winding tape up to the edge of the end faces of the winding. The pressing area is advantageously located behind the winding point in the winding direction in such a way that objects pressed by the additional pressing force soon reach the winding point and are covered by a further winding layer.
Es zeigt sich, dass für den Fall von zweifach gefalteten Produkten aus Papier, wie sie Zeitungen oder Zeitungssektionen darstellen, eine vorübergehende Pressung mit einer zusätzlichen Presskraft in der Grössenordnung von einigen Hundert Newton (ca. 200 bis 1000N) überraschend effektiv ist. Die zusätzliche Presskraft wird beispiels- weise erzeugt mit Hilfe einer an die Peripherie des entstehenden Wickels gepressten, passiv drehenden Pressrolle, deren Achse parallel zur Wickelachse ausgerichtet ist und die beispielsweise in Wickelrichtung vor dem Wickelpunkt und von diesem beabstandet angeordnet ist. Es zeigt sich, dass mit der erfindungsgemässen zusätzlichen Presskraft gewickelte Wickel enger gewickelt und dadurch stabiler sind. Dies zeigt sich beispielsweise daran, dass sie weniger abplatten, wenn sie auf ihrer Peripherie aufstehend positioniert werden. Es zeigt sich auch, dass derart gewickelte Wickel problemloser abgewickelt werden können und dass Produkte aus derart gewickelten Wickeln beim Abwickeln und nachfolgenden Bearbeiten problemloser sind.It turns out that in the case of double-folded paper products such as newspapers or newspaper sections, a temporary pressing with an additional pressing force in the order of a few hundred Newtons (approx. 200 to 1000N) is surprisingly effective. The additional pressing force is generated, for example, with the aid of a passively rotating press roller pressed against the periphery of the resulting roll, the axis of which is aligned parallel to the winding axis and which is arranged, for example, in the winding direction before the winding point and at a distance from it. It can be seen that windings wound with the additional pressing force according to the invention are wound more tightly and are therefore more stable. This can be seen, for example, from the fact that they flatten less when they are positioned on their periphery. It is also shown that windings wound in this way can be handled more easily and that products made from windings wound in this way are easier to handle and subsequent processing.
Für den Fall von Wickeln gefalteter Druckprodukte ist die vorteilhafte Wirkung der erfindungsgemässen zusätzlichen Presskraft, die beim Wickeln an der jeweils äusser- sten Wickellage angreift und über diese auch auf tiefer im Wickel positionierte Lagen wirkt, wohl auf eine mindestens teilweise irreversible oder mindestens nicht so- fort reversible Pressung der Faltkanten, insbesondere des zweiten Falzes und eine ebensolche Komprimierung (Auspressen von Luft) der Produkte zurückzuführen, derart, dass die Produkte einer nächsten Wickellage schon bei der Aufnahme in den Wickel, also bei der ersten Pressung durch das Wickelband weniger deformiert wer- den als dies ohne die zusätzliche Presskraft der Fall ist.In the case of winding folded printed products, the advantageous effect of the additional pressing force according to the invention, which acts on the outermost winding layer during winding and also acts on layers located deeper in the winding, is probably an at least partially irreversible or at least not so the reversible pressing of the folded edges, in particular the second fold, and the same compression (squeezing of air) of the products, in such a way that the products of a next winding layer are less deformed when they are taken up in the winding, i.e. during the first pressing by the winding tape - than is the case without the additional pressing force.
Die zusätzliche Presskraft des erfindungsgemässen Verfahrens ist insbesondere vorteilhaft für das Herstellen von Wickeln, also für Aufwickelvorgänge. Sie kann aber gleichermassen auch für Abwickelvorgänge zur Anwendung kommen.The additional pressing force of the method according to the invention is particularly advantageous for the production of windings, that is for winding operations. However, it can also be used for unwinding operations.
Anhand der folgenden Figuren sollen einige beispielhafte Ausführungsformen des erfindungsgemässen Verfahrens und der erfindungsgemässen Vorrichtung im Detail beschrieben werden. Dabei zeigen:The following figures are used to describe some exemplary embodiments of the method and the device according to the invention in detail. Show:

Figuren 4 und 5 zwei beispielhafte Ausführungsformen von Mitteln zur Erzeugung der zusätzlichen Presskraft (Blickrichtung senkrecht zur Wickelachse).Figures 4 and 5 show two exemplary embodiments of means for generating the additional pressing force (viewing direction perpendicular to the winding axis).
Figur 1 zeigt mit Blickrichtung parallel zur Wickelachse A eine beispielhafte Ausführungsform der erfindungsgemässen Vorrichtung. Es handelt sich dabei um eine im wesentlichen bekannte Wickelvorrichtung, von der nur die wesentlichen Be- standteile dargestellt sind, nämlich ein Mittel zum Halten eines Wickelkerns 1, ein Mittel zum Zuführen der flachen Gegenstände 2 zu einem Wickelpunkt 3 an der Peripherie des Wickelkerns 1 oder eines entstehenden Wickels 4, Mittel zum Zuführen und Spannen des Wickelbandes 5 und ein nicht dargestellter Antrieb, durch den der Wickelkern 1 bzw. der entstehende Wickel 4 in Pfeilrichtung rotierend angetrieben wird. Neu weist die Wickelvorrichtung Mittel 6 zur Erzeugung einer zusätzlichen Presskraft auf die Wickelperipherie eines in der Vorrichtung entstehenden Wickels 4 auf.FIG. 1 shows an exemplary embodiment of the device according to the invention, looking in the direction parallel to the winding axis A. It is an essentially known winding device, of which only the essential Components are shown, namely a means for holding a winding core 1, a means for feeding the flat objects 2 to a winding point 3 on the periphery of the winding core 1 or an emerging winding 4, means for feeding and tensioning the winding tape 5 and a drive, not shown , through which the winding core 1 or the resulting winding 4 is driven to rotate in the direction of the arrow. The winding device now has means 6 for generating an additional pressing force on the winding periphery of a winding 4 created in the device.
Als Mittel zum Halten eines Wickelkerns 1 ist ein um einen fixen Kernschwenk- punkt 10 schwenkbarer Kernarm 11 vorgesehen, an dem der Wickelkern 1 um die Wickelachse A drehbar angeordnet ist. Als Mittel zur Zuführung der flächigen Gegenstände 2 zum Wickelpunkt 3 ist ein Paar von parallel laufenden und voneinander beabstandet angeordneten Förderbändern 12 vorgesehen, von denen nur das Fördertrum dargestellt ist. Auf diesen Förderbändern 12 werden die Gegenstände 2 bei- spielsweise in einer geschuppten Formation lose aufliegend zugeführt. Als Mittel zum Zuführen und Spannen des Wickelbandes 5 ist eine gebremst drehbare Wickelbandrolle 13 und eine Bandumlenkrolle 14 vorgesehen. Zur Unterstützung der Pressung der Gegenstände im Wickelpunkt 3 kann in diesem Bereich eine Rolle 15 angeordnet sein, mit deren Hilfe die Förderbänder 12 und damit die zugeführten Gegen- stände 2 und das Wickelband 5 gegen den Wickelkern 1, bzw. an den entstehenden Wickel 4 gepresst werden.Provided as a means for holding a winding core 1 is a core arm 11 which can be pivoted about a fixed core pivot point 10 and on which the winding core 1 is arranged so as to be rotatable about the winding axis A. As a means for feeding the flat objects 2 to the winding point 3, a pair of conveyor belts 12 running in parallel and spaced from one another is provided, of which only the conveyor run is shown. On these conveyor belts 12, the objects 2 are fed loosely, for example in a shingled formation. As a means for feeding and tensioning the winding tape 5, a braked rotatable winding tape roll 13 and a tape deflection roller 14 are provided. In order to support the pressing of the objects in the winding point 3, a roller 15 can be arranged in this area, with the aid of which the conveyor belts 12 and thus the supplied objects 2 and the winding belt 5 are pressed against the winding core 1 or against the winding 4 that is being created become.
Das Mittel 6 zur Erzeugung der zusätzlichen Presskraft weist beispielsweise eine Pressrolle 20, einen Presshebel 21 und einen Pressantrieb 22 auf, die derart, beispielsweise an einem nicht dargestellten Vorrichtungsgestell angeordnet sind, dass der Pressantrieb 22 die Pressrolle 20 mittels Presshebel 21 gegen die Peripherie des in der Vorrichtung entstehenden Wickels 4 presst und zwar vorteilhafterweise in einem Pressbereich, der in Wickelrichtung hinter dem Wickelpunkt 3 liegt. Wenn der Wickelpunkt 3 im Bereiche des unteren Scheitelpunktes des entstehenden Wickels 4 ist, also etwa in Position 6 Uhr, und die Wickelrichtung im Uhrzeigersinn ausgerichtet ist, ist der Pressbereich vorteilhafterweise, wie in der Figur 1 dargestellt, etwa in einer Position zwischen 4 und 5 Uhr, gegebenenfalls 5 Uhr 30, also um einen Winkel von etwa 15 bis 60° vom Wickelpunkt 3 beabstandet.The means 6 for generating the additional pressing force has, for example, a pressing roller 20, a pressing lever 21 and a pressing drive 22, which are arranged, for example, on a device frame (not shown) in such a way that the pressing drive 22 presses the pressing roller 20 against the periphery of FIG of the device resulting from the winding 4 presses, advantageously in a pressing area which lies behind the winding point 3 in the winding direction. If the If winding point 3 is in the area of the lower vertex of the resulting winding 4, that is to say in the 6 o'clock position, and the winding direction is oriented clockwise, the pressing area is advantageously, as shown in FIG. 1, in a position between 4 and 5 o'clock, if necessary, 5:30 a.m., i.e. at an angle of approximately 15 to 60 ° from the winding point 3.
Der Pressantrieb 22 ist beispielsweise eine um einen fixen Antriebsschwenkpunkt 23 frei schwenkbar angeordnete, beispielsweise hydraulisch betriebene Kolben/Zylinder-Einheit, in der der Druck nach Bedarf geregelt oder ein konstanter Druck aufrechterhalten wird. Der Presshebel 21 ist beispielsweise schwenkbar um einen fixen Hebelschwenkpunkt 24 angeordnet, weist ein frei bewegliches Gelenk 25 auf und ist zwischen Gelenk 25 und Hebelschwenkpunkt 24 mit der Kolben/Zylinder-Einheit 22 gelenkig verbunden. Am dem Hebelschwenkpunkt 24 entgegengesetzten Hebelende ist die Pressrolle 20 frei drehend angeordnet. Das rollentragende Hebelende oder die Pressrolle 20 wird durch eine etwa parallel zu den Zu- führungsbändem 12 ausgerichteten Führung 26 geführt. Die Führung 26 ist schematisch durch eine strichpunktierte Linie angedeutet.The press drive 22 is, for example, a piston / cylinder unit, for example hydraulically operated, which is freely pivotable about a fixed drive pivot point 23 and in which the pressure is regulated as required or a constant pressure is maintained. The press lever 21 is, for example, pivotably arranged about a fixed lever pivot point 24, has a freely movable joint 25 and is articulated between the joint 25 and the lever pivot point 24 with the piston / cylinder unit 22. At the lever pivot point 24 opposite lever end, the press roller 20 is arranged to rotate freely. The roller-carrying lever end or the press roller 20 is guided by a guide 26 oriented approximately parallel to the feed belts 12. The guide 26 is indicated schematically by a dash-dotted line.
Ein Wickelvorgang mit der in der Figur 1 dargestellten Wickelvorrichtung verläuft wie folgt:A winding process with the winding device shown in FIG. 1 proceeds as follows:
Zu Beginn des Wickelvorganges ist der Wickelkern in seiner mit 1' bezeichneten und strichpunktiert dargestellten Position. Das Wickelband 5 ist auf der Wickelbandrolle 13 aufgewickelt und sein Anfang ist an der Peripherie des Wickelkerns 1 befestigt. Der Pressantrieb 22 ist in einem voll ausgefahrenen Zustand oder presst die Pressrolle gegen einen Endanschlag der Führung 26, vorteilhafterweise derart, dass die Pressrolle 20 vom Wickelkern 1 etwas beabstandet ist (strichpunktiert darge- stellte und mit 20' bezeichnete Position der Pressrolle). Sobald die ersten Lagen von Gegenständen 2 auf den Wickelkern 1 gewickelt sind, beginnt die Pressrolle 20 die zusätzliche Presskraft auszuüben, während sie auf der Peripherie des entstehenden Wickels 4 abrollt. Mit fortschreitendem Wickelvorgang wird der Wickeldurchmesser grösser und bewegt sich der Wickelkern 1 gegen oben. Gleichzeitig wird die Pressrolle 20 in der Führung 26 gegen rechts gedrückt, wobei die Presskraft etwa gleich bleibt.At the beginning of the winding process, the winding core is in its position denoted by 1 'and shown in broken lines. The winding tape 5 is wound on the winding tape roll 13 and its beginning is attached to the periphery of the winding core 1. The press drive 22 is in a fully extended state or presses the press roll against an end stop of the guide 26, advantageously in such a way that the press roll 20 is slightly spaced from the winding core 1 (position of the press roll shown by dash-dotted lines and designated 20 ′). As soon as the first layers of Objects 2 are wound on the winding core 1, the press roller 20 begins to exert the additional pressing force while it rolls on the periphery of the resulting winding 4. As the winding process progresses, the winding diameter increases and the winding core 1 moves upwards. At the same time, the pressing roller 20 is pressed against the right in the guide 26, the pressing force remaining approximately the same.
Die ausgezogenen Positionen des Wickelkerns 1 und der Pressrolle 20 illustrieren etwa das Ende des Wickelvorganges.The extended positions of the winding core 1 and the press roller 20 illustrate approximately the end of the winding process.
Figur 1 zeigt auch eine dritte Position der Pressrolle 20 und des Presshebels 21, strichpunktiert dargestellt und mit 20" und 21" bezeichnet. Diese Position wird erreicht, wenn die Kolben/Zylinder-Einheit vollständig eingefahren ist, und dient dazu, die Pressrolle beispielsweise für das Abwickeln aus dem Bereich des Wickels 4 zu entfernen.Figure 1 also shows a third position of the press roller 20 and the press lever 21, shown in dash-dot lines and designated 20 "and 21". This position is reached when the piston / cylinder unit is completely retracted and serves to remove the press roller from the area of the roll 4, for example for unwinding.
Figuren 2 und 3 zeigen mit gleicher Blickrichtung wie Figur 1, aber bedeutend schematischer als diese, zwei weitere beispielhafte Ausführungsformen der erfindungsgemässen Vorrichtung. Die Bestandteile der Vorrichtung sind im wesentlichen dieselben wie diejenigen der Vorrichtung gemäss Figur 1 und sind auch mit denselben Bezugsziffern bezeichnet.FIGS. 2 and 3 show, with the same viewing direction as FIG. 1, but significantly more schematically than this, two further exemplary embodiments of the device according to the invention. The components of the device are essentially the same as those of the device according to FIG. 1 and are also designated with the same reference numbers.
Figur 2 zeigt eine Ausführungsform der erfindungsgemässen Vorrichtung mit zwei Pressbereichen, einer vor und einer hinter dem Wickelpunkt 3. Die beiden Mittel 6.1 und 6.2 zur Erzeugung der zusätzlichen Presskraft weisen wiederum je eine Pressrolle 20.1 und 20.2 auf, je einen Presshebel 21.1 und 21.2 und einen Pressantrieb in Form einer Pressfeder 30.1 und 30.2, die den Presshebel 21.1 bzw. 21.2 gegen die Wickelkern 1 bzw. gegen den entstehenden Wickel 4 treibt und zur Erzeugung der zusätzlichen Presskraft an diesen anpresst.Figure 2 shows an embodiment of the device according to the invention with two press areas, one in front and one behind the winding point 3. The two means 6.1 and 6.2 for generating the additional pressing force each have a press roller 20.1 and 20.2, a press lever 21.1 and 21.2 and one Press drive in the form of a press spring 30.1 and 30.2, which press the press lever 21.1 and 21.2 against Drives the winding core 1 or against the emerging winding 4 and presses it to generate the additional pressing force.
Figur 3 zeigt ein Mittel 6 zur Erzeugung der zusätzlichen Presskraft, das eine Mehrzahl von Pressrollen 20.3, 20.4, 20.5 aufweist. Damit sich die Anordnung von Press- rollen 20.3, 20.4, 20.5 an die während dem Wickelvorgang abnehmende Krümmung der Wickelperipherie anpassen kann, weist sie einen gelenkigen Rollenträger 31 auf, der durch eine Vorspannfeder 32 vorgespannt ist.FIG. 3 shows a means 6 for generating the additional pressing force, which has a plurality of pressing rollers 20.3, 20.4, 20.5. So that the arrangement of press rolls 20.3, 20.4, 20.5 can adapt to the curvature of the winding periphery which decreases during the winding process, it has an articulated roll carrier 31 which is prestressed by a biasing spring 32.
Figuren 4 und 5 zeigen zwei weitere beispielhafte Ausführungsformen von Mitteln 6 zur Erzeugung der zusätzlichen Presskraft mit Blickwinkel senkrecht zur Wickel- achse A. Dargestellt sind je ein Wickel 4 mit Wickelband 5 und von den Mitteln zur Erzeugung der zusätzlichen Presskraft Pressrollen 20 und Teile von Presshebeln (21, 210, 210') und Pressrollenführungen (26).FIGS. 4 and 5 show two further exemplary embodiments of means 6 for generating the additional pressing force with a viewing angle perpendicular to the winding axis A. A respective winding 4 with winding tape 5 and pressing rollers 20 and parts of pressing levers of the means for generating the additional pressing force are shown (21, 210, 210 ') and press roller guides (26).
Figur 4 zeigt eine Pressrolle 20 mit einer axialen Länge, die mindestens so gross ist wie die Breite der aufgewickelten Gegenstände 2, und mit einem zentralen Bereich 40 mit reduziertem Durchmesser. Dieser zentrale Bereich hat eine axiale Ausdehnung, die mindestens so gross ist wie die Breite des Wickelbandes 5. Der Presshebel 21 ist als Gabel ausgebildet und weist auf jeder Seite des Wickels 4 einen die Pressrolle 20 tragenden Presshebelteil 210 und 210' auf. Durch den reduzierten, zentralen Bereich 40 der Pressrolle 20 wird dafür gesorgt, dass die zusätzliche Presskraft nur auf seitliche Bereiche der Wickelperipherie und nicht auf das Wickelband 5 wirkt.FIG. 4 shows a press roll 20 with an axial length that is at least as large as the width of the wound articles 2 and with a central area 40 with a reduced diameter. This central area has an axial extent which is at least as large as the width of the winding tape 5. The press lever 21 is designed as a fork and has a press lever part 210 and 210 'carrying the press roller 20 on each side of the roll 4. The reduced, central area 40 of the press roll 20 ensures that the additional pressing force acts only on lateral areas of the winding periphery and not on the winding tape 5.
Figur 5 zeigt von einem Mittel 6 zur Erzeugung der zusätzlichen Presskraft eine zweiteilige Pressrolle 20, deren Teilrollen 200 und 200' voneinander unabhängig betätigt werden. Die beiden Teilrollen 200 und 200' sind im wesentlichen koaxial - li ¬FIG. 5 shows a means 6 for generating the additional pressing force, a two-part pressing roller 20, the partial rollers 200 and 200 'of which are operated independently of one another. The two partial rollers 200 and 200 'are essentially coaxial - left
angeordnet und je über einen Achsstumpf frei drehbar an den Presshebelteilen 210 und 210' montiert. In diesem Falle ist für jeden Presshebelteil 210 und 210' ein eigener Pressantrieb (nicht dargestellt) vorgesehen, derart, dass die Pressung durch die beiden Teilrollen 200 und 200' voneinander entkoppelt ist.arranged and each rotatably mounted on the press lever parts 210 and 210 'via an axle stub. In this case, a separate press drive (not shown) is provided for each press lever part 210 and 210 'in such a way that the pressure is decoupled from one another by the two part rollers 200 and 200'.
Die in Figur 5 dargestellte Pressrollenanordnung ist insbesondere geeignet für die Herstellung von Wickeln aus flächigen Gegenständen, die auf den beiden Seiten des Wickelbandes verschiedene Dicken aufweisen, also beispielsweise für die Herstellung von Wickeln aus zweifach gefalteten Druckprodukten.The press roller arrangement shown in FIG. 5 is particularly suitable for the production of coils from flat objects which have different thicknesses on the two sides of the winding tape, that is to say for example for the production of coils from double-folded printed products.
Die Pressrollen, wie sie in den Figuren 4 und 5 dargestellt sind, sind beispielsweise anwendbar in den Vorrichtungen, wie sie in den Figuren 1 bis 3 dargestellt sind. Sie sind auch miteinander kombinierbar. The press rolls, as shown in FIGS. 4 and 5, can be used, for example, in the devices as shown in FIGS. 1 to 3. They can also be combined with one another.
