Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung nach den Oberbegriffen
der entsprechenden, unabhängigen Patentansprüche 1 und 8. 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
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., intermediates starting from printing press) are used for transportation and intermediate storage often wrapped in a shingled formation winding. Also for other flat, at least limited flexible objects, for example For textile articles, such winding advantageous transport and / or Represent storage formations.
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 named rolls have a substantially cylindrical winding core and at least one winding tape, wherein the winding tape in a tensioned state along with the shingled formation of the flat objects on the Winding core is wound and this holds together. The end of the wrap band can be closed around the finished roll or in any other suitable way be fixed. The wrapping tape usually has a width that is significantly smaller is the width of the wound objects. Printed products are mostly in Scaly formation wound up; but it is quite possible, this one behind the other arranged, that is, to wind each other not overlapping.
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 breitIn the printing industry usual, such rolls have diameters up to about two meters and can weigh over a ton. The wound products are for example, about 30 to 50 cm wide and scaled so that the product spacing is about 10 cm or less. Usual wrap bands 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 Schuppenformation
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 am Wickelzentium oder ander Wickelperipherie augreifender Antrieb für eine Rotation des
Wickelkerns bzw. des entstehenden Wickels mit einer im wesentlichen konstanten
Umfangsgeschwindigkeit. Derartige Wickelvorrichtungen sind beispielsweise beschrieben
in den Publikationen EP-0243838 (oder US-4775111), EP-0281790
(oder US-4898336), oder US-4523751, die dem Oberbegriff
der unabhängigen Ansprüche 1 und 8 entspricht.To produce the winding winding devices are used, the essential
Ingredients which are: means for holding a winding core (usually
with horizontal winding axis), means for feeding the scale formation
the flat objects to a winding point at the periphery of the winding core
or a resulting coil, means for orderly feeding, the tensioned
Winding tape to the winding point and a winding center or other winding peripherally extending drive for a rotation of the
Winding core or of the resulting coil with a substantially constant
Circumferential speed. Such winding devices are described for example
in the publications EP-0243838 (or US-4775111), EP-0281790
(or US-4898336), or US-4523751, the preamble
the
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 Zuförderbändern 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, übernimmt das gespannte Wickelband die radiale Pressung der Gegenstände im Wickel, gegebenenfalls etwas unterstützt durch eine entsprechende, beispielsweise vom Zuführungsmittel ausgeübte Presskraft im Bereiche des Wickelpunktes.The means for supplying the scale formation have, for example, a pair of Conveyor belts which are substantially tangential to the winding point (e.g., area the lower vertex of the winding core, or the resulting roll) lead and on which the scaly formation of the objects is conveyed loosely becomes. The wrapping tape, for example, between the two feed belts fed, such that the scale formation between winding band and developing Winding is performed in the winding point. In the winding point, in which the supplied objects are successively added to the winding takes over the tensioned winding band the radial pressing of the objects in the winding, optionally somewhat supported by a corresponding, for example, the feeding means applied pressing force in the areas 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 Wickels is pivoted either the supply means or the axis of the hub is moved accordingly. The drive for winding For example, it engages the winding core or at the periphery of the resulting Wickels 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 Wickelvorgang betrieben, wobei die Wickelrotation beispielsweise durch aktives Abziehen der Wickelbandes erzeugt wird.To Wiedererstrellung the scaly formation from a wrap, that is to Unwind, the winding device is essentially opposite to the winding process operated, wherein the winding rotation, for example, by active peeling the winding tape is generated.
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. It turns out that the above-described winding and its manufacture and dissolution the more problematic the smaller and more regular the thickness of the objects The less compressible the objects are and the less tight the scaling is. In winding relatively thick, compressible and / or tightly shingled printed products The winding tape creates a constriction such that the products are at least in the outer layers of the resulting roll to the outside around the Bend tape and the winding in the area of its front sides a larger extent than in the central area, where it is held together by the winding tape. Is it in addition to products that are thicker on one side than on the On the other hand, there is still an asymmetry to constrict such that the two End faces of the coil have different diameters.
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 Umfangsgeschwindigkeit 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.The phenomena mentioned can create problems by causing the winding Destabilize, in that the objects in the wrap take damage or because of the deformation in a scale formation created from the winding again not stable and / or in that it becomes difficult, the peripheral speed of an emerging or degraded roll at the speed of a Feeding or routing of the scaly formation adapt. The mentioned Problems are particularly known in the printing industry for winding relatively thick, twice folded printed products, the second fold in the winding is aligned parallel to the winding axis, such that on the one end of the Wickels unfolded product edges (smaller thickness) and on the other front side of the wrap the first fold of the products, so folded product edges (larger Thickness), lie one on top of the other. Such products are, for example, twice folded Newspapers or sections of newspapers.
Die Erfindung stellt sich nun die Aufgabe, Verfahren und Vorrichtung zur Herstellung 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 invention now has the object, method and apparatus for the production of winding from a large number of flat objects to improve in such a way that the above problems occur less so that too relative thick, relatively compressible and / or irregular, in particular one-sided thick Objects with better results can be wound up into coils, too if they are as a narrow scale formation, ie with small distances between to be wound up 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 in the independent claims are defined.
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 gepresst, 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 Wickelradius. 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 Wickelpunkt gelangen und von einer weiteren Wickellage gedeckt wird.According to the invention, the flat objects are in a resulting winding during the winding process not only by the tensioned winding tape (central Area) and their own stiffness (lateral areas) pressed against the winding core, but they are temporarily exposed to an additional pressing force. The additional pressing force acts locally during the wrapping process in one of the Winding point spaced, substantially stationary pressing area on the periphery of the resulting coil and has a component in the direction of the winding radius. The additional pressing force, for example, over the entire winding width be exercised, but is advantageously limited to peripheral areas next to the winding tape to the edge of the winding end faces. Advantageously located the pressing area in the winding direction behind the winding point, such that by the additional pressing force pressed objects soon after in the winding point arrive and is covered by another 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 beispielsweise 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 two-folded paper products, like them Newspaper or newspaper sections, a temporary press with one additional pressing force of the order of a few hundred Newton (approx. 200 to 1000N) is surprisingly effective. The additional pressing force, for example generated by means of a pressed to the periphery of the resulting coil, passively rotating press roll whose axis is aligned parallel to the winding axis and spaced, for example in the winding direction before the winding point and from this is arranged. It turns out that with the inventive additional Press wound wound coil wound tight and thus are more stable. this shows For example, remember that they have less decks when on their periphery be positioned upright. It also turns out that such wound coils can be handled more easily and that products are wound from such Winding when unwinding and subsequent editing are easier.
Für den Fall von Wickeln gefalteter Druckprodukte ist die vorteilhafte Wirkung der erfindungsgemässen zusätzlichen Presskraft, die beim Wickeln an der jeweils äussersten Wickellage angreift und über diese auch auf tiefer im Wickel positionierte Lagen wirkt, wohl auf eine mindestens teilweise irreversible oder mindestens nicht sofort 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 werden als dies ohne die zusätzliche Presskraft der Fall ist.In the case of winding folded printed products, the beneficial effect of according to the invention additional pressing force, which when winding on the outermost each Winding layer attacks and over this also on lower in the winding positioned layers works, probably at least partially irreversible or at least not immediately reversible pressing of the folded edges, in particular of the second fold and a attributed the same kind of compression (squeezing air) of the products, such that the products of a next winding layer already in the recording in the Winding, so less deformed at the first pressing by the winding tape as this 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 inventive method is particularly advantageous for making windings, so for winding operations. But she can equally be used for unwinding operations.
