Abstract

The roll (32), which consists of a winding core (12) and printed products (14) wound thereon in overlapping fashion (S) with a winding band (10), is mounted rotatably, and freely supported, on two endless carrier belts (28, 28'). The carrier belts (28, 28') are each guided round two rotatably mounted rollers (24, 26), of which the roller (26) is in each case in active connection with a drive (52). The winding band (10) becomes detached from the roll (32) in the region where the roll (32) bears on the carrier belts (28, 28') and is wound under constant tensile stress onto a band reel (48). The printed products (14) which become detached from the roll (32) during unwinding are transported away from the carrier belts (28, 28') and fed by means of a despatch conveyor (58) to the next processing station. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Abwickeln von zusammen mit einem Wickelband in Schuppen­formation auf einem Wickelkern aufgewickelten Druckpro­dukten gemäss dem Oberbegriff des Anspruches 1.The present invention relates to a device for unwinding printed products wound together with a winding tape in a scale formation on a winding core according to the preamble of claim 1.

Eine solche Vorrichtung ist beispielsweise aus der EP-A2 01 42 745 und der entsprechenden US-PS 4,597,541 be­kannt. Der Wickelkern ist bei dieser Vorrichtung an einer ortsfesten Lagerung drehbar gelagert. Für das Weg­führen der abgewickelten Schuppenformation ist ein Ste­tigförderer an den Wickel bzw. den Wickelkern anstell­bar. Bei dieser Anordnung ist es notwendig, dass der Stetigförderer so ausgebildet ist, dass die Druckproduk­te bei den verschiedenen Lagen, die der Stetigförderer im Verlaufe des Abwickelvorganges einnimmt, sicher abge­führt werden. Dies erfordert eine aufwendige Konstruk­tion des Stetigförderers. Ebenfalls muss bei dieser be­kannten Vorrichtung der Wickel auf eine Lagerwelle oder dergleichen aufgeschoben werden, bevor er auf die Lage­rung aufgesetzt werden kann, was wiederum entsprechende Geräte erfordert.Such a device is known for example from EP-A2 01 42 745 and the corresponding US Pat. No. 4,597,541. In this device, the winding core is rotatably mounted on a fixed bearing. A continuous conveyor can be placed on the winding or the winding core to remove the developed scale formation. With this arrangement, it is necessary for the continuous conveyor to be designed in such a way that the printed products are reliably removed in the various positions which the continuous conveyor assumes in the course of the unwinding process. This requires a complex construction of the continuous conveyor. Also in this known device, the winding must be pushed onto a bearing shaft or the like before it can be placed on the bearing, which in turn requires corresponding devices.

Aus der DE-OS 22 07 556 ist eine weitere Vorrichtung zum Abwickeln von Druckprodukten bekannt. Bei dieser Vor­richtung sind die Druckprodukte in geschuppter Form zwi­schen zwei Wickelbändern, einem Wickelbänderpaar, einge­klemmt auf einer Trommel aufgewickelt. Beim Abwickeln der auf der Trommel gespeicherten Druckprodukte wird das Wickelbandpaar zusammen mit den Druckprodukten von der Trommel abgespult, und die beiden Bänder laufen nach dem Ausleeren ihres Inhalts an einen Wegförderer zu ihren einzelnen, getrennten Speicherrollen auseinander. Der Schuppenstrom wird durch das Wickelbandpaar in ungefähr horizontaler Richtung vom Wickel weggeführt. Dabei wird die gesamte Trommel zum Ausgleich der mehr oder weniger dick aufgewickelten Schicht der Druckprodukte höhenver­stellt. Diese Vorrichtung eignet sich nicht zum Ab­wickeln von nur mit einem Wickelband in Schuppenforma­tion auf einem Wickelkern aufgewickelten Druckprodukten, weil diese oberschlächtig abgeführt werden. Ebenfalls ist es bei dieser Vorrichtung notwendig, dass die Trom­mel mit dem auf der Nabe aufgewickelten Wickel, welcher ein erhebliches Gewicht haben kann, infolge seiner ab­nehmenden Dicke aufwärts bewegt werden muss, damit der Abwickelpunkt auf derselben Höhe bleibt.DE-OS 22 07 556 a further device for unwinding printed products is known. In this device, the printed products are wound in a scaly form between two winding tapes, a pair of winding tapes, and are wound on a drum. When unwinding of the printed products stored on the drum, the pair of winding tapes is unwound from the drum together with the printed products, and after the contents have been emptied, the two tapes run apart on a conveyor to their individual, separate storage rolls. The shingled stream is led away from the roll in an approximately horizontal direction by the pair of winding tapes. The height of the entire drum is adjusted to compensate for the more or less thickly wound layer of the printed products. This device is not suitable for unwinding printed products that are wound on a winding core with only one wrapping tape in a shingled formation, because they are discharged oversized. It is also necessary with this device that the drum with the winding wound on the hub, which can be of considerable weight, has to be moved upwards due to its decreasing thickness so that the unwinding point remains at the same height.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrun­de, eine Vorrichtung der eingangs genannten Art zu schaffen, die eine vereinfachte Konstruktion aufweist und einfacher gehandhabt werden kann.The present invention has for its object to provide a device of the type mentioned, which has a simplified construction and is easier to handle.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst. Da­durch, dass der Wickel auf einem endlosen Tragband dreh­bar und frei abgestützt gelagert ist, kann auf eine La­gerwelle und auf eine Lagerung für diese Lagerwelle ver­zichtet werden. Der Wickel kann einfach auf die Tragbän­der aufgesetzt werden, und es ist nicht mehr nötig, dass der Wickel mit Hilfe von entsprechenden Geräten auf die Lagerwelle aufgeschoben werden muss.This object is achieved according to the invention by the features of the characterizing part of claim 1. Because the winding is rotatably and freely supported on an endless support belt, a bearing shaft and a bearing for this bearing shaft can be dispensed with. The winding can simply be placed on the carrier tapes, and it is no longer necessary for the winding to be pushed onto the bearing shaft with the aid of appropriate devices.

Die Rollen sind auf Wellen, welche vorzugsweise an einem Gestell ortsfest angeordnet sind, drehbar gelagert. Bei dieser Ausführungsform besitzt das Tragband entweder eine gewisse Elastizität, so dass dessen tragender Trum durch das Gewicht des Wickels verlängert wird, und der Wickel zwischen den beiden Rollen eine stabile Lage ein­nimmt, oder das Tragband ist im nichtbelasteten Zustand lose um die Rollen gelegt, so dass das rücklaufende Trum gespannt wird, während das tragwirksame Trum durch das Gewicht des Wickels durchhängt.The rollers are rotatably mounted on shafts, which are preferably arranged in a fixed position on a frame. In this embodiment, the carrier tape either has a certain elasticity, so that its supporting strand is extended by the weight of the winding, and the winding takes a stable position between the two rollers, or the carrier tape is loosely placed around the rollers in the unloaded state, so that the returning strand is tensioned, while the load-bearing strand sags due to the weight of the wrap.

In einer bevorzugten Ausführungsform ist eine Rolle an einer Welle drehbar gelagert, welche ortsfest an dem Ge­stell angeordnet ist, währenddem die andere Welle in ho­rizontaler Richtung veränderbar angeordnet ist. Dadurch wird erreicht, dass ein Tragband mit sehr wenig Elasti­zität auch im nichtbelasteten Zustand eine definierte Lage einnimmt, und bei Belastung durch den Wickel oder den leeren Wickelkern die veränderbare Welle sich soweit gegen die ortsfeste Welle verschieben kann, dass das tragwirksame Trum des Tragbandes durch das Gewicht des Wickels oder des Wickelkerns soweit nach unten gedrückt wird, dass der Wickel oder der Wickelkern ebenfalls eine stabile Lage zwischen den beiden Rollen einnimmt. Des weiteren kann bei dieser Ausführungsform der Durchhang des tragwirksamen Trums mit abnehmendem Wickelgewicht reguliert werden, so dass der Wickel auch gegen das Ende des Abwickelvorganges noch eine stabile Lage zwischen den Rollen einnimmt.In a preferred embodiment, a roller is rotatably mounted on a shaft which is arranged in a stationary manner on the frame, while the other shaft is arranged to be changeable in the horizontal direction. This ensures that a lanyard with very little elasticity assumes a defined position even when not in use, and that the changeable shaft can move against the stationary shaft when the liner or empty winding core is loaded so that the load-bearing strand of the lanyard is supported by the The weight of the winding or the winding core is pressed down so far that the winding or the winding core also assumes a stable position between the two rollers. Furthermore, in this embodiment, the sag of the load-bearing strand can be regulated with a decreasing winding weight, so that the winding still assumes a stable position between the rollers even at the end of the unwinding process.

Um die Sicherheit der Vorrichtung zu erhöhen und ein seitliches Abspringen des Wickels vom Tragband zu ver­ hindern, ist der Wickel zwischen seitlichen, im wesent­lichen parallel zum Tragband angeordneten Führungen auf dem Tragband gelagert.To increase the safety of the device and to ver a lateral jumping of the wrap from the carrier tape prevent the winding between the lateral guides, which are arranged essentially parallel to the carrier tape, on the carrier tape.

Bei einer besonders einfachen und bevorzugten Ausfüh­rungsform der Erfindung ist der Wickel auf zwei parallel verlaufenden, voneinander beabstandeten Tragbändern ab­gestützt; dabei wird das Wickelband nicht zwischen den Tragbändern und dem Wickel eingeklemmt, was die Stabili­tät des Wickels vergrössert und ein freies Wegführen des Wickelbandes ermöglicht.In a particularly simple and preferred embodiment of the invention, the winding is supported on two parallel, spaced-apart support tapes; the winding tape is not clamped between the carrying tapes and the winding, which increases the stability of the winding and enables the winding tape to be carried away freely.

Bei einer Ausbildungsform, die ein sehr schnelles Be­schleunigen und wieder Abbremsen des Wickels erlaubt, sind das Tragband oder die Tragbänder mit dem Antrieb wirkverbunden. Die Bandspule wird mittels demselben An­trieb derart angetrieben, dass eine Schlupfkupplung zwi­schen der Bandspule und dem Antrieb dafür sorgen kann, dass das Wickelband unter einer stetigen Zugbeanspru­chung steht.In the case of an embodiment which allows the winding to be accelerated and braked very quickly, the carrier tape or tapes are operatively connected to the drive. The tape reel is driven by means of the same drive in such a way that a slip clutch between the tape reel and the drive can ensure that the winding tape is under constant tensile stress.

Bei einer besonders einfachen und geeigneten Weiterbil­dung der Vorrichtung ist die Bandspule unterhalb den tragwirksamen Trums der Tragbänder gelagert. Das Wickel­band überkreuzt dadurch die tragwirksamen Trums bevor sich die Druckprodukte, in ihrer Förderrichtung gesehen, vom Wickel lösen. Dadurch kommen die vom Wickel abge­wickelten Druckprodukte bei der Trennung von diesem auf die Tragbänder zu liegen, und sie werden mittels diesen vom Wickel weggeführt.In a particularly simple and suitable further development of the device, the tape reel is mounted below the effective strands of the supporting tapes. As a result, the winding tape crosses the load-bearing strands before the printed products, seen in their conveying direction, detach from the winding. As a result, the printed products unwound from the roll come to rest on the carrier tapes when separated from them and are guided away from the roll by means of these.

Um die Sicherhcit der Vorrichtung noch weiter zu erhö­hen, ist bei einer weiteren bevorzugten Ausführungsform eine auf den Wickelkern in Richtung des Tragbandes ein­wirkbare Begrenzung vorgesehen. Dadurch wird ein Abrol­len des Wickels vom Band, auch wenn dieses in unbelaste­tem Zustand stark gespannt ist und die Achsen der Rollen nicht verschiebbar gelagert sind, sowie grosse Beschleu­nigungs- oder Verzögerungskräfte auftreten, verhindert.In order to increase the safety of the device still further, in a further preferred embodiment, a limitation which can be applied to the winding core in the direction of the carrier tape is provided. This prevents the roll from unrolling from the tape, even if it is tightly tensioned in the unloaded state and the axes of the rolls are not displaceably mounted, and large acceleration or deceleration forces occur.

Im folgenden wird anhand der Zeichnung ein Ausführungs­beispiel des Erfindungsgegenstandes näher beschrieben. Es zeigt rein schematisch:

  • Fig. 1 eine Seitenansicht der Vorrichtung mit einem vollen Wickel, wobei der vordere Teil des Gestells nicht dargestellt ist,
  • Fig. 2 eine teilweise geschnittene Stirnseitenan­sicht der Vorrichtung, und
  • Fig. 3 dieselbe Ansicht wie Fig. 1, jedoch mit einem grösstenteils entleerten Wickel.
An exemplary embodiment of the subject matter of the invention is described in more detail below with reference to the drawing. It shows purely schematically:
  • 1 is a side view of the device with a full wrap, the front part of the frame is not shown,
  • Fig. 2 is a partially sectioned end view of the device, and
  • Fig. 3 is the same view as Fig. 1, but with a largely empty coil.

In der Fig. 1 ist die Vorrichtung zum Abwickeln von zu­sammen mit einem Wickelband 10 in Schuppenformation S auf einem Wickelkern 12 aufgewickelten Druckprodukten 14 mit 16 bezeichnet. Ein solcher Wickel 32 ist in der CH-PS 642 602 und der entsprechenden US-PS 4 438 618 nä­her beschrieben.In Fig. 1, the device for unwinding together with a winding tape 10 in scale formation S on a winding core 12 printed products 14 is designated 16. Such a winding 32 is described in more detail in CH-PS 642 602 and the corresponding US-PS 4,438,618.

An einem Gestell 18 sind zwei Wellen 20, 22 ortsfest an­geordnet. An jeder Welle 20, 22 sind zwei Rollen 24, 26 drehbar gelagert. Eine obere gemeinsame, an die Rollen 24, 26 angelegte Tangente verläuft horizontal. Um je­weils zwei entsprechende Rollen 24, 26 ist je ein endlo­ses Tragband 28 geführt. Auf den oberen Trumen 30 dieser Tragbänder 28, 28′ liegt der Wickel 32, bestehend aus dem Wickelkern 12, den aufgewickelten Druckprodukten 14 und dem ebenfalls aufgewickelten Wickelband 10, auf und ist frei drehbar und nicht weiter abgestützt gelagert. Unter dem Gewicht des Wickels 32 hängen die tragwirksamen Trume 30 durch, so dass sie gegen die beiden Rollen 24, 26 hin ansteigend verlaufen. Der Wickel 32 wird von den Tragb­ändern 28, 28′ um den Umschliessungswinkel α umschlos­sen. Beidseits des Wickels 32 sind Führungen 34 angeord­net, welche am Gestell 18 befestigt sind, vgl. auch Fig. 2. Die Führungen 34 bestehen aus einem Rohrprofil und sind als rechteckförmige Rahmen ausgebildet. Zwischen den Stirnwänden 36 des Wickels 32 und den Führungen 34 ist ein kleiner Luftspalt vorgesehen, so dass der Wickel 32 auf den Tragbändern 28, 28′ um seine Drehachse 38 frei drehen kann, ohne dass der Wickel mit den Führungen 34 in Berührung steht. Auf jeder Stirnseite 36 des Wickels 32 sind die Führungen 34 paarweise symmetrisch zur vertika­len Ebene A durch die Drehachse 38 des Wickels 32 ange­ordnet. Die Führungen 34 jedes Paares sind so weit von­einander beabstandet, dass der Wickelkern 12 sicher immer zwischen zwei gegenüberliegenden Führungen 34 zu liegen kommt. Die Führungen 34 verhindern ein seitliches Ablau­fen der Rolle ab den Tragbändern 28, 28′ falls aus ir­gendwelchen Gründen der Wickel 32 sich aus der Mitte ver­schieben sollte. Die Führungen 34 verringern aber auch das Unfallrisiko für das Bedienungspersonal, denn sie vermindern die Gefahr mit dem doch sich schnell drehenden Wickel 32 in Berührung zu kommen.Two shafts 20, 22 are arranged in a stationary manner on a frame 18. There are two rollers 24, 26 on each shaft 20, 22 rotatably mounted. An upper common tangent applied to the rollers 24, 26 runs horizontally. An endless conveyor belt 28 is guided around each two corresponding rollers 24, 26. On the upper run 30 of these tapes 28, 28 'is the winding 32, consisting of the winding core 12, the wound printed products 14 and the also wound winding tape 10, and is freely rotatable and not supported. The load-bearing strands 30 sag under the weight of the winding 32, so that they run upwards towards the two rollers 24, 26. The winding 32 is enclosed by the support tapes 28, 28 'by the wrap angle α. Guides 34 are arranged on both sides of the winding 32 and are fastened to the frame 18, cf. also Fig. 2. The guides 34 consist of a tubular profile and are designed as a rectangular frame. Between the end walls 36 of the winding 32 and the guides 34, a small air gap is provided, so that the winding 32 on the support bands 28, 28 'can rotate freely about its axis of rotation 38 without the winding being in contact with the guides 34. On each end face 36 of the winding 32, the guides 34 are arranged in pairs symmetrically to the vertical plane A through the axis of rotation 38 of the winding 32. The guides 34 of each pair are spaced so far apart that the winding core 12 always comes to rest between two opposite guides 34. The guides 34 prevent the roller from running off to the side from the support bands 28, 28 'if, for any reason, the winding 32 should move from the center. However, the guides 34 also reduce the risk of accidents for the operating personnel, because they reduce the risk of coming into contact with the winding 32, which nevertheless rotates quickly.

Eine die Sicherheit nochmals erhöhende Massnahme ist in Fig. 1 gestrichelt eingezeichnet. Am Wickelkern 12 ist mit Speichen 40 ein Wellenstummel 42 abgestützt. Aus Fig. 2 ist ersichtlich, dass der Wellenstummel 42 (ge­strichelt dargestellt) seitlich über die Stirnseiten 36 des Wickels 32 vorsteht und zwischen je zwei der symme­trisch angeordneten Führungen 34 zu liegen kommt. Ein Abrollen des Wickels 32 ab den Tragbändern 28, 28′ in ihrer Laufrichtung ist damit auch verhindert. Eine Be­grenzung der zulässigen Verschiebung des Wickels 32 in Richtung der Tragbänder 28, 28′ kann selbstverständlich auch auf andere Weise als hier vorgeschlagen ausgebildet sein.A measure which further increases safety is shown in dashed lines in FIG. 1. A stub shaft 42 is supported on the winding core 12 with spokes 40. From FIG. 2 it can be seen that the stub shaft 42 (shown in dashed lines) projects laterally beyond the end faces 36 of the winding 32 and comes to rest between two of the symmetrically arranged guides 34. A roll of the roll 32 from the support bands 28, 28 'in their running direction is also prevented. A limitation of the permissible displacement of the winding 32 in the direction of the support tapes 28, 28 'can of course also be designed in a different way than proposed here.

Auf die Sicherung mittels dem Wellenstummel 42 oder einer anderen Begrenzung kann verzichtet werden, wenn ein genügend grosser Durchhang der oberen Trums 30 durch das Gewicht des Wickels 32, respektive des Wickelkernes 12 garantiert wird. Wie oben beschrieben, sind die Wel­len 20, 22 ortsfest am Gestell 18 angeordnet. Werden endlose Tragbänder 28, 28′ mit sehr geringer Elastizität eingesetzt, so ist es notwendig, dass diese Tragbänder 28, 28′ im unbelasteten Zustand sehr lose um die Rollen 24, 26 geführt sind; diese werden sich erst unter dem Gewicht des Wickelkerns 12 oder des gesamten Wickels 32 an die Rollen 24, 26 satt anlegen und damit den notwen­digen Durchhang der tragwirksamen Trums 30 sicherstel­len, wobei die rücklaufenden Trums sich spannen. Werden hingegen elastische Tragbänder 28, 28′ eingesetzt, so können diese auch im unbelasteten Zustand, unter Vor­spannung an den Rollen 24, 26 anliegen. Durch das Ge­wicht des Wickelkernes 12 oder des Wickels 32 werden die Tragbänder 28, 28′ gedehnt. Somit kann ein genügender Durchhang erzielt werden. Eine weitere Möglichkeit ist in der Fig. 1 gestrichelt dargestellt. Die Welle 20 ist in horizontalen Längsführungen 44 am Gestell 18 gela­gert. Eine Druckfeder 46 ist dafür besorgt, dass die Tragbänder 28, 28′ auch im unbelasteten Zustand immer angespannt sind. Unter Belastung durch den Wickelkern 12 oder den Wickel 32 wird die Feder zusammengedrückt und die Welle 20 kommt am federseitigen Ende der Längsfüh­rung 44 zum Anschlag. Das Gewicht des Wickels 32 oder des Wickelkerns 12 bewirkt also eine Bewegung der Rollen 24 in Richtung gegen die Rollen 26.Securing by means of the shaft stub 42 or another limitation can be dispensed with if a sufficiently large sag of the upper runs 30 is guaranteed by the weight of the winding 32 or the winding core 12. As described above, the shafts 20, 22 are arranged stationary on the frame 18. If endless carrier tapes 28, 28 'with very low elasticity are used, it is necessary that these carrier tapes 28, 28' are guided very loosely around the rollers 24, 26 in the unloaded state; these will only abut against the rollers 24, 26 under the weight of the winding core 12 or the entire winding 32 and thus ensure the necessary sag of the load-bearing strands 30, the returning strands tensing. On the other hand, elastic support straps 28, 28 'are used, so that they can rest against the rollers 24, 26 even when they are not under load. The weight of the winding core 12 or the winding 32 Straps 28, 28 'stretched. Sufficient sag can thus be achieved. Another possibility is shown in dashed lines in FIG. 1. The shaft 20 is mounted in horizontal longitudinal guides 44 on the frame 18. A compression spring 46 ensures that the straps 28, 28 'are always tense even in the unloaded state. When loaded by the winding core 12 or the winding 32, the spring is compressed and the shaft 20 comes to a stop at the spring-side end of the longitudinal guide 44. The weight of the winding 32 or the winding core 12 thus causes the rollers 24 to move in the direction against the rollers 26.

In der Fig. 2 ist besonders gut sichtbar, dass zwischen den beiden, auf der Welle 22 angeordneten Rollen 26 die Bandspule 48 zum Aufwickeln des vom Wickel 32 abgewik­kelten Wickelbandes 10 angeordnet ist. Die Rollen 26 drehen mit der Welle 22 mit, und die Welle 22 ist dreh­bar am Gestell 18 gelagert. Die Welle 22 ist mittels einem Kettentrieb 50 mit dem Antrieb 52 wirkverbunden. Es ist selbstverständlich, dass anstelle des Kettentrie­bes 50, wie allgemein bekannt, ein Zahnrad- oder Riemen­trieb treten kann. Der Antrieb 52 ist mittels einem zweiten Kettentrieb 54 mit einer Schlupfkupplung 56 wirkverbunden. Der Abtrieb der Schlupfkupplung 56 steht mit der Bandspule 48 in Wirkverbindung. Aus der Fig. 1 ist ersichtlich, dass infolge der unterschiedlichen Uebersetzungen der Kettentriebe 50, 54 die Bandspule 48 mit einer grösseren Rotationsgeschwindigkeit angetrieben wird als die Rollen 26. Die Funktionsweise des Antriebes wird weiter unten noch beschrieben.2 that the tape reel 48 is arranged between the two rollers 26 arranged on the shaft 22 for winding the winding tape 10 unwound from the winding 32. The rollers 26 rotate with the shaft 22, and the shaft 22 is rotatably mounted on the frame 18. The shaft 22 is operatively connected to the drive 52 by means of a chain drive 50. It goes without saying that, as is well known, a chain drive or belt drive can take the place of the chain drive 50. The drive 52 is operatively connected to a slip clutch 56 by means of a second chain drive 54. The output of the slip clutch 56 is operatively connected to the tape reel 48. It can be seen from FIG. 1 that, due to the different ratios of the chain drives 50, 54, the tape reel 48 is driven at a greater rotational speed than the rollers 26. The mode of operation of the drive will be described further below.

In Bewegungsrichtung B der oberen Trums 30 gesehen ist nach den Rollen 26 ein Wegförderer 58 angeordnet. Dieser Wegförderer 58 ist ein bekannter Bandförderer.Seen in the direction of movement B of the upper runs 30, a conveyor 58 is arranged after the rollers 26. This conveyor 58 is a known belt conveyor.

Die Vorrichtung 16 zum Abwickeln von Wickeln 32 funktio­niert wie folgt: Ein voller Wickel 32 wird auf die obe­ren Trume 30 der Tragbänder 28, 28′ gelegt. Dies kann mit bekannten Fördermaschinen, wie Krane oder Stapler, geschehen. Falls die Wickel 32 von der Seite her auf das Tragband 28 gestellt werden, so werden zu diesem Zwecke die seitlichen Führungen 34 vom Gestell 18 entfernt oder aus dem Bereich des Wickels 32 geschwenkt. Da der Wickel 32 zwischen die Rollen 24, 26 zu liegen kommt und dafür gesorgt ist, wie oben beschrieben, dass durch die Bela­stung durch den Wickel 32 ein Durchhang der Tragbänder 28, 28′ erfolgt, nimmt der Wickel eine stabile Lage im Bereich der Mitte zwischen den beiden Rollen 24, 26 ein. Der Wickel 32 kommt nie auf den Rollen 24, 26 zur Aufla­ge, sondern er liegt immer zwischen den Rollen 24, 26 nur auf den Tragbändern 28, 28′ auf. Anschliessend wer­den die Führungen 34 wieder auf das Gestell 18 montiert oder in ihre ursprüngliche Lage zurückgeschwenkt. Die Wickel 32 können aber auch von oben auf die Tragbänder 28, 28′ aufgelegt werden. Ein Entfernen der Führungen 34 ist dann nicht notwendig. Der Wickel 32 wird so auf die Tragbänder 28, 28′ gelegt, dass das äussere Ende des Wickelbandes 10 in Bewegungsrichtung B der oberen Trums 30 weggeführt und an der Bandspule 48 befestigt werden kann.The device 16 for unwinding of coils 32 works as follows: A full winding 32 is placed on the upper strands 30 of the support tapes 28, 28 '. This can be done with known carriers, such as cranes or forklifts. If the coils 32 are placed from the side onto the carrier tape 28, the side guides 34 are removed from the frame 18 for this purpose or pivoted out of the area of the coil 32. Since the winding 32 comes to lie between the rollers 24, 26 and ensures that, as described above, the sagging of the support tapes 28, 28 'takes place due to the load from the winding 32, the winding takes a stable position in the middle between the two rollers 24, 26. The winding 32 never comes to rest on the rollers 24, 26, but it is always between the rollers 24, 26 only on the support bands 28, 28 '. The guides 34 are then reassembled on the frame 18 or pivoted back into their original position. The winding 32 can also be placed on the support tapes 28, 28 'from above. It is then not necessary to remove the guides 34. The winding 32 is placed on the carrying tapes 28, 28 'in such a way that the outer end of the winding tape 10 is guided away in the direction of movement B of the upper run 30 and can be attached to the tape reel 48.

Das Moment des nun eingeschalteten Antriebes 52 wird mittels den Kettentrieben 50, 54 auf die Welle 22, die Rollen 26 und die Tragbänder 28, 28′ sowie auf die Band­spule 48 übertragen. Die Drehrichtung der Rollen 26 ist mit C bezeichnet. Da der Wickel 32 frei drehbar auf den Tragbändern 28, 28′ aufliegt und durch sein Gewicht einen Durchhang der oberen Trums 30 bewirkt, ist seine Lage zwischen den Rollen 24, 26 definiert, und er dreht sich in Richtung des Pfeiles D mit derselben Abwickelge­schwindigkeit, wie sich die oberen Trums 30 der Tragbän­der 28, 28′ in Richtung B bewegen. Da die Uebersetzung des Kettentriebes 54 grösser ist als jene des Ketten­triebes 50 wird das Wickelband 10 mittels der Schlupf­kupplung 56 immer unter einer definierten Zugspannung gehalten. Wie aus den Figuren 1 und 3 ersichtlich, trennt sich das Wickelband 10 im Mittelbereich zwischen den Rollen 24 und 26, innerhalb des Umschliessungswin­kels α, vom Wickel 32 und überkreuzt die tragwirksamen Trums 30 der Tragbänder 28, 28′ Die in Schuppenforma­tion S auf dem Wickelkern 12 aufgewickelten Druckproduk­te 14 trennen sich vom Wickel 32 kurz nach der Ablösung des Wickelbandes 10 und kommen auf die oberen Trums 30 zur Anlage.The moment of the drive 52 which is now switched on is transmitted to the shaft 22 by means of the chain drives 50, 54 Rollers 26 and the tapes 28, 28 'and transferred to the reel 48. The direction of rotation of the rollers 26 is designated C. Since the winding 32 rests freely rotatably on the carrying bands 28, 28 'and causes a sag of the upper runs 30 due to its weight, its position between the rollers 24, 26 is defined and it rotates in the direction of arrow D at the same unwinding speed, how the upper runs 30 of the carrier tapes 28, 28 'move in the direction B. Since the ratio of the chain drive 54 is greater than that of the chain drive 50, the winding tape 10 is always kept under a defined tension by means of the slip clutch 56. As can be seen from Figures 1 and 3, the winding tape 10 separates in the central region between the rollers 24 and 26, within the angle of wrap α, from the winding 32 and crosses the effective strands 30 of the support tapes 28, 28 'in scale formation S on the winding core 12 wound printed products 14 separate from the winding 32 shortly after the winding tape 10 has come off and come to rest on the upper runs 30.

Die Druckprodukte 14 werden mittels den Tragbändern 28, 28′ vom Wickel 32 weggefördert bis in den Bereich der Rollen 26. Dort werden die Druckprodukte 14 an den Weg­förderer 58 übergeben, welcher diese zur nächsten Verar­beitungsstation weiterfördert. Der ändernde Drehzahlun­terschied zwischen den mit ungefähr konstanter Drehzahl drehenden Rollen 26 und der stetig grösser werdenden Bandspule 48 mit dem aufgewickelten Wickelband 10 wird durch die Schlupfkupplung 56 ausgeglichen. Das Wickel­band 10 steht dauernd unter einer ungefähr konstanten Zugspannung.The printed products 14 are conveyed away by means of the carrying belts 28, 28 'from the winding 32 to the area of the rollers 26. There the printed products 14 are transferred to the conveyor 58, which conveys them to the next processing station. The changing speed difference between the rollers 26 rotating at approximately constant speed and the continuously increasing tape reel 48 with the wound winding tape 10 is compensated for by the slip clutch 56. The winding tape 10 is constantly under an approximately constant tension.

In Fig. 3 ist die Grösse des vollen Wickels 32 strich­punktiert gezeichnet. Durch das Abwickeln der Druckpro­dukte 14 vom Wickelkern 12 bewegt sich dieser in Rich­tung des Pfeiles E nach unten und nähert sich stetig den oberen Trums 30 der Tragbänder 28, 28′, bis schlussend­lich alle Druckprodukte 14 weggeführt sind. Das Ende des Wickelbandes 10 wird nun vom Wickelkern gelöst, welcher nun wieder zur freien Verfügung für die Uebernahme von neuen Druckprodukten 14 in einer Aufwickelstation steht.In Fig. 3 the size of the full roll 32 is shown in dash-dotted lines. By unwinding the printed products 14 from the winding core 12, this moves in the direction of arrow E downwards and steadily approaches the upper run 30 of the support tapes 28, 28 'until finally all printed products 14 are removed. The end of the winding tape 10 is now detached from the winding core, which is now again freely available for the takeover of new printed products 14 in a winding station.

Die Welle 22 weist im Bereich der Bandspule 48 ein ab­koppelbares Wellenstück auf. Zum Auswechseln einer vol­len gegen eine leere Bandspule 48, wird die volle von der Schlupfkupplung 56 gelöst und zusammen mit dem auf­gewikkelten Wickelband 10 vom Wellenstück entfernt, und eine leere Bandspule 48 wird in umgekehrter Reihenfolge eingesetzt. Dies ist auch möglich, falls die Bandspule 48 an einer separaten Drehwelle, welche am Gestell 18 angeordnet ist, drehbar gelagert ist. Das wickelkernsei­tige Ende des Wickelbandes 10 kann auch mit dem Wickel­kern 12 in Verbindung bleiben, und die mit dem Wickel­band 10 umwickelte Bandspule 48 steht zusammen mit dem Wickelkern 12 zur freien Verfügung, oder das Wickelband 10 wird vom Wickelkern 12 getrennt, die volle Bandspule 48 steht somit gesondert zur freien Verfügung.The shaft 22 has a detachable shaft piece in the area of the tape reel 48. To replace a full reel with an empty reel 48, the full is released from the slip clutch 56 and removed together with the wound winding tape 10 from the shaft piece, and an empty reel 48 is inserted in the reverse order. This is also possible if the tape reel 48 is rotatably mounted on a separate rotary shaft which is arranged on the frame 18. The end of the winding tape 10 on the winding core side can also remain in connection with the winding core 12, and the tape reel 48 wrapped with the winding tape 10 is freely available together with the winding core 12, or the winding tape 10 is separated from the winding core 12, the full tape reel 48 stands thus at your own disposal.

Die Tragbänder 28, 28′ übernehmen bei der in den Figuren 1 bis 3 gezeigten Ausführungsform der Erfindung die Auf­gabe des Stetigförderers zum Wegführen der abgewickelten Schuppenformation S vom Wickel 32 an den Wegförderer 58. Es ist aber auch durchaus denkbar, dass der Wickelkern 12 auf den endlosen Tragbändern 28, 28′ drehbar und frei abgestützt gelagert ist, und die abgewickelten Druckpro­dukte 14 in einen separaten Stetigförderer vom Wickel 32 wegtransportiert werden.The carrying tapes 28, 28 'take over in the embodiment of the invention shown in Figures 1 to 3 the task of the continuous conveyor to lead away the developed scale formation S from the winding 32 to the conveyor 58. But it is also quite conceivable that the winding core 12 on the endless straps 28, 28 'rotatable and free is supported and the unwound printed products 14 are transported away from the winding 32 in a separate continuous conveyor.

Es ist auch denkbar, dass nur die Bandspule 48 mittels dem Antrieb 52 angetrieben wird. Der Antrieb des Wickels 32 und der Tragbänder 28, 28′ erfolgen nur über das Wickelband 10; es überträgt die Antriebskraft von der Bandspule 48 auf den Wickel 32, welcher sich auf den frei oder leicht gebremst bewegbaren Tragbändern 28, 28′ abrollt.It is also conceivable that only the reel 48 is driven by the drive 52. The drive of the winding 32 and the carrier tapes 28, 28 'take place only via the winding tape 10; it transmits the driving force from the reel 48 to the winding 32, which rolls on the freely or slightly braked movable tapes 28, 28 '.
