Abstract

The winding apparatus comprises an elevationally adjustable bearing arrangement for rotatably mounting and driving a winding core. Underneath the bearing arrangement, there is provided a conveyor-belt arrangement which is driven by partially training or wrapping around the winding core or, as the case may be, a product package wound up thereon. The conveyor-belt arrangement conveys printed products, which are to be wound up, to the winding core. Prior to winding up the printed products, a winding band is unwound from the winding core and wound onto a winding-band spool. For this purpose, the winding-band spool is connected by means of a slip friction coupling with respective rolls and thus with the conveyor-belt arrangement. During the winding-up of the winding band in conjunction with the printed products onto the winding core, the winding-band spool is braked. A detaching roller for detaching the free end of the winding band wound-up on the winding core as a winding-band supply is drivably coupled with the winding-band spool by means of an endless belt. The endless belt takes the free end of the winding band from the detaching roller to the winding-band spool.

Description

Die vorliegende Erfindung betrifft eine Einrichtung zum Aufwickeln von, insbesondere in einer Schuppenformation anfallenden Druckereiprodukten, wie Zeitungen, Zeitschriften und dergleichen, zusammen mit einem unter Zugspannung stehenden Wickelband auf einen Wickelkern zu einem Wickel, gemäss dem Oberbegriff des Anspruches 1.The present invention relates to a device for winding up printed products, in particular in a scale formation, such as newspapers, magazines and the like, together with a winding tape under tension on a winding core to form a winding, according to the preamble of claim 1.

Eine Einrichtung, sowohl zum Auf- als auch zum Abwickeln von Druckereiprodukten zusammen mit einem Wickelband zu einem bzw. von einem Wickel ist aus der EP-A-0 281 790 bzw. der entsprechenden US-A 4,898,336 und der EP-A-0 298 267 bekannt. Diese weist einen in vertikaler Richtung an einem Gestell verschiebbaren Schlitten auf, an welchem eine Lageranordnung für den den Wickel tragenden Wickelkern vorgesehen ist. Die Lageranordnung weist einen Antriebsmotor auf, um den auf die Lageranordnung abgesetzten Wickelkern anzutreiben. Unterhalb der Lageranordnung ist ein Bandförderer mit zwei voneinander seitlich beabstandeten losen Förderbändern vorgesehen, welcher wippenartig gelagert und gegen den Wickel hin vorgespannt ist. Die Wickelbänder sind alleine durch das teilweise Umschlingen des Wickelkerns bzw. des darauf aufgewickelten Wickels von diesem angetrieben. An der Wippe des Bandförderers ist eine Umlenkrolle frei drehbar gelagert, um welche das vom Wickel herkommende Wickelband geführt ist und von welcher das Wickelband zu einer am Gestell ortsfest gelagerten und über einen eigenen Antriebsmotor angetriebenen Wickelbandspule verläuft. Zum Aufwickeln der anfallenden Druckereiprodukte ist der Wickelkern mittels des geregelten Antriebsmotores der Lageranordnung im Aufwickelsinn angetrieben, während die Wickelbandspule mit einer drehenden elektrischen Maschine gekuppelt ist, die zum Spannen des Wickelbandes mit Bremsschlupf läuft. Beim Abwickeln ab dem Wickelkern wird dieser mittels des Antriebsmotors in Abwickelrichtung angetrieben und die die Vorratsspule antreibende elektrische Maschine läuft mit Antriebsschlupf um das Wickelband gespannt zu halten. Diese bekannte Einrichtung eignet sich insbesondere zum Auf- bzw. Abwickeln von Druckereiprodukten zu bzw. ab einem grossen Wickel, wobei das Verhältnis zwischen dem Durchmesser des fertigen Wickels und des Wickelkerns gross, typischerweise 3:1 bis 5:1 ist. Die bekannte Einrichtung ist aber antriebsmässig und insbesondere was die Steuerung der Antriebe betrifft, aufwendig.A device, both for winding and unwinding printed products together with a winding tape to or from a winding, is known from EP-A-0 281 790 or the corresponding US-A 4,898,336 and EP-A-0 298 267 known. This has a slide which can be displaced in the vertical direction on a frame and on which a bearing arrangement is provided for the winding core carrying the winding. The bearing arrangement has a drive motor in order to drive the winding core set down on the bearing arrangement. Below the bearing arrangement, a belt conveyor with two laterally spaced loose conveyor belts is provided, which is rocker-like and biased against the winding. The winding tapes are driven solely by the partial wrapping around the winding core or the winding wound thereon. A deflection roller is freely rotatably mounted on the rocker of the belt conveyor, around which the winding belt coming from the winding is guided and from which the winding belt runs to a winding belt spool that is fixedly mounted on the frame and driven by its own drive motor. The winding core is used to wind up the resulting printed products of the regulated drive motor of the bearing arrangement is driven in the winding direction, while the winding tape reel is coupled to a rotating electrical machine that runs to tension the winding tape with brake slip. When unwinding from the winding core, the latter is driven in the unwinding direction by means of the drive motor and the electric machine driving the supply reel runs with drive slip in order to keep the winding tape taut. This known device is particularly suitable for winding or unwinding printed products to or from a large roll, the ratio between the diameter of the finished roll and the winding core being large, typically 3: 1 to 5: 1. However, the known device is drive-related and, in particular as far as the control of the drives is concerned, complex.

Aus der CH-A-652 379 bzw. der entsprechenden US-A-4,532,750 ist eine Einrichtung zum Aufwickeln von Druckereiprodukten in Schuppenformation auf einen Wickelkern bekannt, bei welcher vor dem Aufwickeln das Wickelband von einer im innern des Wickelkerns vorgesehenen Vorratsspule abgezogen und auf eine Wickelbandspule aufgewickelt wird. Zum Ablösen des Wickelbandes ab der Vorratsspule ist im Innern des Wickelkerns ein Stift vorgesehen, der gegen die Vorratsspule vorgespannt ist und beim Drehen der Vorratsspule in deren Abwickelsinn mittels eines separaten Antriebs zwischen das Wickelbandende und die Vorratsspule einsticht. Das abgelöste Wickelbandende wird durch eine Oeffnung aus dem Wickelkern herausgeführt, von einem Vorschubrollenpaar erfasst und durch eine entlang einer Wippe zum Zuführen der Druckereiprodukte zum Wickelkern verlaufenden Führung und mittels einer weiteren Wippe an den Umfang der Wickelbandspule geführt. Sind einige Windungen des Wickelbandes auf die Wickelbandspule aufgewickelt, wird der separate Antrieb mitsamt der angetriebenen Rolle des Vorschubrollenpaares aus dem Bereich des Wickelkerns verschwenkt. Weist das Wickelband einen Klettenreissverschluss auf, um das Wickelband auf der Vorratsspule zusammenzuhalten, so ist dieser vom Wickelbandende beabstandet vorgesehen, damit der Stift das Wickelbandende ablösen und das Vorschubrollenpaar das Wickelband erfassen kann, bevor der Klettenreissverschluss zu öffnen ist.From CH-A-652 379 or the corresponding US-A-4,532,750 a device for winding printed products in scale formation on a winding core is known, in which prior to winding the winding tape is drawn off from a storage spool provided inside the winding core and onto one Winding tape reel is wound. To detach the winding tape from the supply reel, a pin is provided inside the winding core, which is biased against the supply reel and sticks between the winding tape end and the supply reel when the supply reel is rotated in its unwinding direction by means of a separate drive. The detached end of the winding tape is led out of the winding core through an opening, gripped by a pair of feed rollers and through a guide running along a rocker for feeding the printed products to the winding core and by means of a further rocker on the Scope of the winding tape spool out. If a few turns of the winding tape are wound onto the winding tape reel, the separate drive together with the driven roller of the feed roller pair is pivoted out of the area of the winding core. If the winding tape has a Velcro zipper to hold the winding tape together on the supply spool, this is provided at a distance from the end of the winding tape so that the pin can detach the end of the winding tape and the pair of feed rollers can grip the winding tape before the Velcro zipper is to be opened.

Weiter ist eine ähnlich aufgebaute, an der Wippe zum Zuführen der Druckereiprodukte zum Wickelkern angeordnete Ablöseeinrichtung zum Ablösen des Wickelbandendes ab einem in einer überdeckten Umfangsnut des Wickelkerns angeordneten Wickelbandvorrat, aus der EP-A-0 280 949 bzw. der entsprechenden US-A-4,795,105 bekannt. Das von der nächsten Wickellage des Wickelbandvorrates abgelöste Bandende wird umgelenkt und einer von der Wippe entfernten Bandspule zugeführt.Furthermore, a similarly constructed detaching device for detaching the end of the winding tape, which is arranged on the rocker for feeding the printed products to the winding core, from a supply of winding tape arranged in a covered circumferential groove of the winding core, is known from EP-A-0 280 949 and the corresponding US-A-4,795,105 known. The end of the tape that has been detached from the next winding position of the winding tape supply is deflected and fed to a tape reel that is removed from the rocker.

Im weitern ist in der EP-A-0 310 784 ein Klettenreissverschluss für ein Wickelband beschrieben. Das Wickelband ist zusammen mit Druckereiprodukten auf einen Wickel aufgewickelt und weist an seinem äusseren Endbereich auf der dem Wickel zugewandten Seite einen Hakenflor auf, der mit einem Schlingenfloor zusammenwirkt, welcher auf der Aussenseite des Wickelbandes vorgesehen ist. Der Schlingenflor erstreckt sich über eine bestimmte Länge des Wickelbandes, sodass vom Durchmesser des Wickels unabhängig der Hakenflor immer an einem Bereich des Schlingenflors zur Anlage kommt. Der Haken- wie auch Schlingenflor flankieren je einen Abstandhalter, dessen Dicke höchstens der Höhe des zugeordneten Floors entspricht. Zum Oeffnen des Klettenreissverschlusses wird vom Ende des Wickelbandes her mittels eines spatelartigen Werkzeuges zwischen die dem Hakenfloor und dem Schlingenfloor zugeordneten Abstandhalter eingefahren.Furthermore, EP-A-0 310 784 describes a Velcro zipper for a winding tape. The winding tape is wound together with printed products on a winding and has at its outer end area on the side facing the winding a hook pile which interacts with a loop pile which is provided on the outside of the winding tape. The loop pile extends over a certain length of the winding tape, so that regardless of the diameter of the roll, the hook pile always comes into contact with an area of the loop pile. The hook and loop pile flank a spacer, the thickness of which corresponds at most to the height of the assigned floor. In order to open the Velcro zipper, a spatula-like tool is inserted from the end of the winding tape between the spacers assigned to the hook floor and the loop floor.

Ausgehend von eingangs erwähntem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine gattungsgemässe Einrichtung zu schaffen, die bezüglich Ihres Antriebs äusserst einfach aufgebaut ist.Starting from the prior art mentioned at the outset, it is an object of the present invention to provide a generic device which is extremely simple in terms of its drive.

Diese Aufgabe wird durch eine gattungsgemässe Einrichtung, die die Merkmale des kennzeichnenden Teiles des Anspruchs 1 aufweist, gelöst. Für die Wickelbandspule ist kein eigener aufwendiger Antrieb notwendig, sondern diese wird von der Förderbandanordnung angetrieben, welche ihrerseits auch keinen eigenen Antrieb aufweist, sondern vom Wickelkern her angetrieben ist.This object is achieved by a generic device which has the features of the characterizing part of claim 1. No separate, complex drive is necessary for the winding tape reel, but this is driven by the conveyor belt arrangement, which in turn does not have its own drive, but is driven by the winding core.

Eine erfindungsgemässe Einrichtung gemäss Anspruch 2 eignet sich besonders gut zum automatischen Betrieb.A device according to the invention is particularly well suited for automatic operation.

Weitere, bevorzugte Ausbildungsformen der erfindungsgemässen Einrichtung sind in den weiteren abhängigen Ansprüchen angegeben.Further preferred embodiments of the device according to the invention are specified in the further dependent claims.

Die vorliegende Erfindung wird nun anhand eines in der Zeichnung dargestellten Ausführungsbeispieles beschrieben. Es zeigen rein schematisch:

The present invention will now be described with reference to an embodiment shown in the drawing. It shows purely schematically:

Die in der Figur 1 gezeigte Aufwickeleinrichtung 10, weist einen auf dem Boden abgestützten Sockel 12 auf, an welchem eine aufrechtstehende Führungssäule 14 verankert ist. Die Führungssäule 14 weist zwei voneinander beabstandete und gegen einander offene U-förmige Führungsprofile 16 auf, an welchen eine Lageranordnung 17 zum drehbaren Lagern und Antreiben eines hohlzylinderförmigen Wickelkerns 18 höhenverstellbar geführt ist. Auf den Wickelkern 18 werden in Schuppenformation S und in Zuführrichtung F zugeführte Druckereiprodukte 19 zusammen mit einem unter Zugspannung stehenden Wickelband 20 zu einem Wickel 21 aufgewickelt.The winding device 10 shown in FIG. 1 has a base 12 which is supported on the floor and to which an upright guide column 14 is anchored. The guide column 14 has two spaced apart and mutually open U-shaped guide profiles 16, on which a bearing arrangement 17 for rotatably supporting and driving a hollow cylindrical winding core 18 is guided in a height-adjustable manner. Printed products 19 supplied in scale formation S and in the feed direction F are wound onto the winding core 18 together with a winding tape 20 under tension to form a winding 21.

Die Lageranordnung 17 weist einen Wagen 22 auf, welcher über Führungsrollen 22′ in den Führungsprofilen 16 verschiebbar gelagert ist. Zwischen den beiden Führungsprofilen 16 ist eine in vertikaler Richtung verlaufende Spindel 24 ortsfest angeordnet und mittels eines schematisch angedeuteten Motores 26 in beiden Drehrichtungen um ihre Achse antreibbar. Der Wagen 22 ist laufmutterartig mit der Spindel 24 verbunden. Durch Verdrehen der Spindel 24 in der einen Richtung wird somit der Wagen 22 angehoben und durch Verdrehen in entgegengesetzter Richtung abgesenkt.The bearing assembly 17 has a carriage 22 which is slidably mounted on guide rollers 22 'in the guide profiles 16. Between the two guide profiles 16, a spindle 24 extending in the vertical direction is arranged in a fixed position and by means of a schematically indicated motor 26 in both directions of rotation about its axis drivable. The carriage 22 is connected to the spindle 24 like a running nut. By rotating the spindle 24 in one direction, the carriage 22 is thus raised and lowered by rotating in the opposite direction.

Am Wagen 22 sind auf gleicher Höhe zwei den Wickelkern 18 von innen im Reibschluss antreibende Antriebsräder 28, 28′ sowie eine den Wickelkern 18 in Kontakt mit den Antriebsrädern 28, 28′ haltende, frei drehbar gelagerte Spannrolle 30 vorgesehen. Die beiden Antriebsräder 28, 28′ sind über einen schematisch angedeuteten Kettentrieb 32 miteinander verbunden und mittels eines schematisch angedeuteten Antriebsmotors 34 in beiden Drehrichtungen antreibbar. Die Spannrolle 30 ist in der Höhe verstellbar um in der, in der Figur 1 mit ausgezogenen Linien gezeigten Lage den Wickelkern 18 gegen die Antriebsräder 28, 28′ zu Spannen bzw. um in der strichpunktiert angedeuteten Lage 30′ den Wickelkern 18 freizugeben, damit dieser von den Antriebsrädern 28, 28′ abgehoben bzw. auf diese aufgesetzt werden kann. Diese Antriebsart für einen hohlzylindrischen Wickelkern ist beispielsweise in der EP-A 0 161 569 bzw. der enstprechenden US-A-4,601,436 und 4,682,741 eingehend beschrieben. Es versteht sich jedoch, dass auch ein verschieden aufgebauter Antrieb für den Wickelkern 18 der nicht zwingend hohlzylindrisch zu sein hat, vorgesehen werden kann. Eine in gleicher Art und Weise höhenverstellbare Lageranordnung 17 ist aus der EP-A-0 281 790 bzw. der entsprechenden US-A-4,898,336 und der EP-A-0 298 267 bekannt.On the carriage 22 two at the same level the winding core 18 from the inside driving friction wheels 28, 28 'and a winding core 18 in contact with the drive wheels 28, 28' holding, freely rotatably mounted tensioning roller 30 are provided. The two drive wheels 28, 28 'are connected to one another via a schematically indicated chain drive 32 and can be driven in both directions of rotation by means of a schematically indicated drive motor 34. The tensioning roller 30 is adjustable in height in order to tension the winding core 18 against the drive wheels 28, 28 'in the position shown in solid lines in FIG. 1 or to release the winding core 18 in the position 30 indicated by dash-dotted lines, so that this from the drive wheels 28, 28 'can be lifted or placed on this. This type of drive for a hollow cylindrical winding core is described in detail, for example, in EP-A 0 161 569 or the corresponding US Pat. Nos. 4,601,436 and 4,682,741. However, it goes without saying that a differently designed drive for the winding core 18, which does not necessarily have to be hollow cylindrical, can also be provided. A bearing arrangement 17 that is height-adjustable in the same way is known from EP-A-0 281 790 or the corresponding US-A-4,898,336 and EP-A-0 298 267.

Der Sockel 12 weist zwei zueinander parallele schaftförmige Tragglieder 36, 36′ auf, auf welche eine unterhalb der Lageranordnung 17 vorgesehene Förder- und Wickelbandeinheit 38 aufgesteckt ist. Diese Förder- und Wickelbandeinheit 38 weist zwei zueinander parallele und voneinander seitlich beabstandete Seitenschilder 40 auf, die über rohrförmige Träger 42, 42′ durch welche hindurch die Tragglieder 36, 36′ verlaufen, miteinander fest verbunden sind.The base 12 has two mutually parallel shaft-shaped support members 36, 36 ', one of which is below the Bearing arrangement 17 provided conveyor and winding belt unit 38 is attached. This conveyor and winding belt unit 38 has two mutually parallel and laterally spaced side plates 40, which are firmly connected to one another via tubular supports 42, 42 'through which the support members 36, 36' extend.

Die Förder- und Wickelbandeinheit 38 weist eine Förderbandanordnung 44 auf, deren Förderbänder 46 mit ihren oberen Trumen 46′ den Wickelkern 18 bzw. den darauf befindlichen, in der Figur 1 strichpunktiert angedeuteten Wickel 21 unterschlächtig teilweise umschlingen. Die Förderbänder 46 sind um ortsfeste Walzen 50, 50′ geführt. Die, in Zuführrichtung F (Fig. 1) der Druckereiprodukte 19, die zusammen mit dem, in der Figur 1 strichpunktiert angedeuteten Wickelband 20 auf den Wickelkern 18 zu einem Wickel 21 aufgewickelt werden und in Schuppenformation S anfallen, gesehen am Anfang der Förderbandanordnung 44 angeordneten Walzen 50 sitzen drehfest auf einer gemeinsamen Lagerwelle 56, die an den Seitenschildern 40 frei drehbar gelagert ist. Dadurch wird der Gleichlauf der beiden Förderbänder 46 sichergestellt. Die Walzen 50′ am von den Walzen 50 entfernten Ende der Förderbandanordnung 44 sitzen frei drehbar auf einer gemeinsamen Welle 58, die über im Aufspulsinn A (Fig. 1) wirksame Freiläufe 60 an zwei Lagerschildern 62 abgestützt ist. Die Lagerschilder 62 sind zwischen den beiden Walzen 50′ angeordnet und an den dem Tragglied 36′ zugeordneten Träger 42′ und einer, zwischen diesem und der Welle 58 vorgesehenen, die beiden Seitenschilder 40 am diesseitigen Ende miteinander verbindenden Traverse 64 befestigt, siehe auch Fig. 2. Ausserhalb der beiden Walzen 50′ ist je eine Hülse 66 vorgesehen, die über einen entgegen dem Aufspulsinn A wirksamen Hülsenfreilauf 68 auf der Welle 58 sitzt. Jede Hülse 66 durchdringt eine im wesentlichen dreieckförmige, mit der zugeordneten Walze 50′ über Bolzen 70 drehfest verbundene Platte 72, die über eine Rutschkupplung 74 mit der Hülse 66 zusammenwirkt. Im Aufspulsinn A ist somit die Hülse 66 mit der Welle 58 starr gekoppelt und entgegen dem Aufspulsinn A von dieser entkoppelt.The conveyor and winding belt unit 38 has a conveyor belt arrangement 44, the conveyor belts 46 with their upper runs 46 'loosely loop around the winding core 18 or the winding 21 located thereon, indicated by dash-dotted lines in FIG. The conveyor belts 46 are guided around stationary rollers 50, 50 '. The, in the feed direction F (FIG. 1) of the printed products 19, which, together with the winding tape 20 indicated by dash-dotted lines in FIG. 1, are wound onto the winding core 18 to form a winding 21 and accumulate in scale formation S, viewed at the beginning of the conveyor belt arrangement 44 Rollers 50 are non-rotatably seated on a common bearing shaft 56 which is freely rotatably mounted on the side plates 40. This ensures the synchronism of the two conveyor belts 46. The rollers 50 'at the end of the conveyor belt assembly 44 distant from the rollers 50 are freely rotatable on a common shaft 58 which is supported by two free plates 60 which are effective in the winding direction A (FIG. 1). The end shields 62 are arranged between the two rollers 50 'and attached to the support member 36' associated with the support 42 'and a provided between the latter and the shaft 58, the two side shields 40 connecting the cross member 64 at this end, see also Fig. 2. Outside of two rollers 50 ', a sleeve 66 is provided, which sits on an effective against the winding sense A sleeve freewheel 68 on the shaft 58. Each sleeve 66 penetrates a substantially triangular, with the associated roller 50 'rotatably connected by bolt 70 plate 72 which cooperates with the sleeve 66 via a slip clutch 74. In the winding direction A, the sleeve 66 is thus rigidly coupled to the shaft 58 and decoupled from the winding direction A counter to this.

Zwischen den beiden Lagerschildern 62 ist auf der Welle 58 eine Wickelbandspule 76 für das Wickelband 20 frei drehbar gelagert, siehe insbesondere Fig. 2. Der Durchmesser der Wickelbandspule 76 ist grösser als der Durchmesser der Walzen 50′ zusammen mit den diese umgreifenden Förderbändern 46. Die Wickelbandspule 76 ist radförmig aufgebaut und weist einen einstückig an einer Scheibe 78 angeformten Radkranz 78′ auf. Am Radkranz 78′ sind entlang dessen Umfang Permanentmagnete 80 angeordnet um das diesseitige Ende 82 des Wickelbandes 20 mit der Wickelbandspule 76 zu verbinden.Between the two end shields 62, a winding tape spool 76 for the winding tape 20 is freely rotatably mounted on the shaft 58, see in particular Fig. 2. The diameter of the winding tape spool 76 is larger than the diameter of the rollers 50 'together with the conveyor belts 46 encompassing them Winding tape reel 76 is wheel-shaped and has a wheel rim 78 'integrally formed on a disk 78. On the rim 78 'permanent magnets 80 are arranged along its circumference to connect this end 82 of the winding tape 20 to the winding tape reel 76.

An der Scheibe 78 sind verteilt mehrere Bremsglieder 84 angeordnet, die mit beidseitig der Scheibe 78 vorgesehenen und drehfest auf der Welle 58 sitzenden Bremsscheiben 86 zusammenwirken. Die Bremsglieder 84 weisen an ihren den Bremsscheiben 86 zugewandten Enden Bremsbeläge auf, die mittels einer, in der Figur 2 nicht gezeigten Druckfeder mit vorgegebener Kraft gegen die Bremsscheiben 86 gepresst werden. Die Bremswirkung zwischen der Wickelbandspule 76 und den Bremsscheiben 86 ist grösser als die entsprechende Wirkung der Rutschkupplungen 74.Distributed on the disk 78 are a plurality of brake members 84 which cooperate with brake disks 86 provided on both sides of the disk 78 and seated in a rotationally fixed manner on the shaft 58. The brake members 84 have, at their ends facing the brake disks 86, brake linings which are pressed against the brake disks 86 with a predetermined force by means of a compression spring (not shown in FIG. 2). The braking effect between the winding tape reel 76 and the brake discs 86 is greater than the corresponding effect of the slip clutches 74.

Die Funktionsweise der Kupplung zwischen den Walzen 50′ und somit den Förderbändern 46 und der Wickelbandspule 76 ist wie folgt: werden die Walzen 50′ entgegen dem Aufspulsinn A angetrieben, sind die Hülsenfreiläufe 68 aktiv, was bedeutet, dass die Welle 58 von den Walzen 50′ entkoppelt ist. Die Welle 58 ist am Drehen entgegen dem Aufspulsinn A durch die Freiläufe 60 gehindert, was zur Folge hat, dass beim Abspulen des auf die Wickelbandspule 76 aufgewickelten Wickelbandes 20 diese mit etwa konstanter Kraft gebremst wird. Sind hingegen die Walzen 50′ im Aufspulsinn A angetrieben, werden die Hülsen 66 über die Rutschkupplungen 74 mitgedreht, sodass durch die nun inaktiven Hülsenfreiläufe 68 die Welle 58 mit den Hülsen 66 mitdreht. Da die von den Bremsgliedern 84 verursachte Kopplung zwischen der Wickelbandspule 76 und der Welle 58 grösser ist als die Kopplung über die Rutschkupplung zwischen den Walzen 50′ und den Hülsen 66, dreht in diesem Fall die Wickelbandspule 76 mit der Welle 58 mit, und ein durch das auf die Wickelbandspule 76 aufzuwickelnde Wickelband 20 verursachter Schlupf zwischen der Wickelbandspule 76 und den Walzen 50′ wird durch die Rutschkupplung aufgenommen. Dies hat zur Folge, dass beim Aufspulen des Wickelbandes 20 auf die Wickelbandspule 76 das Wickelband 20 unter etwas geringerer Zugspannung steht als beim Aufwickeln des Wickelbandes 20 zusammen mit den Druckereiprodukten 19 auf den Wickelkern 18 unter gleichzeitigem Abspulen ab der Wickelbandspule 76.The operation of the coupling between the rollers 50 'and thus the conveyor belts 46 and the winding reel 76 is as follows: If the rollers 50' are driven against the winding direction A, the sleeve freewheels 68 are active, which means that the shaft 58 from the rollers 50 'Is decoupled. The shaft 58 is prevented from rotating against the winding direction A by the freewheels 60, which has the consequence that when the winding tape 20 wound on the winding tape reel 76 is braked, it is braked with approximately constant force. In contrast, the rollers 50 'are driven in the winding direction A, the sleeves 66 are rotated via the slip clutches 74, so that the shaft 58 rotates with the sleeves 66 through the now inactive sleeve freewheels 68. Since the coupling caused by the brake members 84 between the winding tape spool 76 and the shaft 58 is greater than the coupling via the slip clutch between the rollers 50 'and the sleeves 66, in this case the winding tape spool 76 rotates with the shaft 58 and through the winding tape 20 to be wound onto the winding tape reel 76 causes slippage between the winding tape reel 76 and the rollers 50 'is absorbed by the slip clutch. The consequence of this is that when the winding tape 20 is wound onto the winding tape spool 76, the winding tape 20 is under a somewhat lower tensile stress than when the winding tape 20 is wound together with the printed products 19 onto the winding core 18 with simultaneous unwinding from the winding tape spool 76.

Zwischen den beiden Förderbändern 46 ist eine als Ablösewalze 88 ausgebildete Umlenkeinrichtung 90 für das Wickelband 20 vorgesehen. Die Ablösewalze 88 ist in jenem Bereich vorgesehen, in welchem, bei auf die oberen Trume 46′ der Förderbänder 46 abgesetztem Wickelkern 18 bzw. Wickel 21 in Zuführrichtung F gesehen, die teilweise Umschlingung durch diese oberen Trume 46′ erfolgt, oder mit andern Worten, in jenem Bereich in welchem die mittels der Förderbänder 46 zugeführte Schuppenformation S auf den Wickelkern 18 bzw. den Wickel 21 aufläuft. Das mit seinem einen Ende am Wickelkern 18 befestigte und darauf aufgewickelte Wickelband 20 verläuft entgegen Pfeilrichtung B vom Wickelkern 18 herkommend um die Ablösewalze 88 herum und von dieser zur Wickelbandpule 76 um dort im Aufspulsinn A aufgespult, bzw. in Gegenrichtung von dieser abgezogen zu werden (Fig. 1).Between the two conveyor belts 46, a deflection device 90 designed as a detaching roller 88 is provided for the winding belt 20. The detaching roller 88 is provided in that area in which, on the upper runs 46 ' the conveyor belts 46 offset winding core 18 or winding 21 seen in the feed direction F, the partial wrapping takes place through these upper runs 46 ', or in other words, in that area in which the scale formation S fed by means of the conveyor belts 46 on the winding core 18 or the winding 21 runs up. The winding tape 20 fastened with one end to the winding core 18 and wound thereon runs in the opposite direction of the arrow B from the winding core 18 around the detaching roller 88 and from there to the winding tape reel 76 in order to be wound up there in the winding-up direction A, or to be pulled off in the opposite direction ( Fig. 1).

Die Ablösewalze 88 ist an einer in Richtung gegen den Wickelkern 18 vorgespannten Wippe 92 frei drehbar gelagert, welche ihrerseits um eine an den Seitenschildern 40 befestigte Lagerwelle 94 schwenkbar ist (Fig. 1 und 2). Die Wippe 92 weist zwei zueinander parallele und in Richtung der Lagerwelle 94 voneinander beabstandete Wippenschilder 96 auf, die an einer auf der Lagerwelle 94 frei drehbar sitzenden Lagerhülse 98 befestigt und durch einen Lagerschaft 100, an welchem die Ablösewalze 88 frei drehbar gelagert ist, miteinander verbunden sind. Die über Kugellager 100′ am Lagerschaft 100 drehbar gelagerte Ablösewalze 88 weist entlang ihrem Umfang Permanentmagnete 102 auf, um, wie dies weiter unten im Detail beschrieben ist, das freie Wickelbandende 82 vom auf den Wickelkern 18 aufgewickelten Wickelbandvorrat abzulösen und in Richtung gegen die Wickelbandspule 76 umzulenken. Eine Ablösewalze 88 dieser Art und eine dazu geeignete Ausbildungsform des Wickelbandes 20 ist in der nachveröffentlichten CH-Patentanmeldung 00971/90-0 vom 23. März 1990 ausführlich beschrieben.The detaching roller 88 is freely rotatably mounted on a rocker 92 biased in the direction against the winding core 18, which in turn can be pivoted about a bearing shaft 94 fastened to the side plates 40 (FIGS. 1 and 2). The rocker 92 has two rocker plates 96 which are parallel to one another and spaced apart in the direction of the bearing shaft 94, which are fastened to a bearing sleeve 98 which is freely rotatable on the bearing shaft 94 and are connected to one another by a bearing shaft 100 on which the detaching roller 88 is freely rotatably mounted are. The detaching roller 88, which is rotatably mounted on the bearing shaft 100 via ball bearings 100, has permanent magnets 102 along its circumference in order, as described in detail below, to detach the free end of the winding tape 82 from the supply of winding tape wound on the winding core 18 and towards the winding tape reel 76 redirect. A release roller 88 of this type and a suitable embodiment of the winding tape 20 is described in detail in the subsequently published CH patent application 00971 / 90-0 dated March 23, 1990.

Die Wippenschilder 96 weisen an ihrem freien Endbereich eine unterhalb des dem Tragglied 36 zugeordneten Trägers 42 vorstehende Nase 96′ auf. Im Bereich dieser Nasen 96′ sind die Wippenschilder 96 mittels eines unterhalb des Trägers 42 und parallel zu diesem verlaufenden, nicht gezeigten Querkörper miteinander verbunden. An diesem Querkörper stützt sich das eine Ende einer Druckfeder 106 ab, die andernends an einer Stellschraube 108 anliegt, die in eine am betreffenden Träger 42 befestigte Mutter 108′ eingreift. Durch Verdrehen der Stellschraube 108 ist die Kraft einstellbar, mit welcher die Ablösewalze 88 gegen den Wickelkern 18 bzw. den darauf aufgewickelten Wickel 21 gedrückt wird. Die Schwenkbewegung der Wippe 92 entgegen dem Uhrzeigersinn ist durch das Anstossen der Nasen 96′ am Träger 42 begrenzt.The rocker plates 96 have at their free end region a nose 96 'protruding below the support 42 assigned to the support member 36'. In the area of these lugs 96 ', the rocker plates 96 are connected to one another by means of a cross body, not shown, running below the carrier 42 and parallel to the latter. On this cross body, one end of a compression spring 106 is supported, the other abuts against an adjusting screw 108 which engages in a nut 108 'attached to the carrier 42 in question. The force with which the detaching roller 88 is pressed against the winding core 18 or the winding 21 wound thereon can be adjusted by turning the adjusting screw 108. The pivoting movement of the rocker 92 counterclockwise is limited by the abutment of the lugs 96 'on the carrier 42.

Zwischen der Ablösewalze 88 und der Wickelbandspule 76 sind Führungsmittel 110 vorgesehen, um das mittels der Ablösewalze 88 abgelöste freie Ende 82 des Wickelbandes 20 von der Ablösewalze 88 an die Wickelbandspule 76 zu verbringen und um das Wickelband 20 zu führen. Ein mit seinem oberen Trum 112′ die Wickelbandspule 76 mit der Ablösewalze 88 unterschlächtig verbindendes Endlosband 112 umschlingt diese teilweise und ist um Umlenkrollen 114 bzw. 114′ geführt. Die benachbart zur Wickelbandspule 76 vorgesehenen Umlenkrollen 114 sind an den Lagerschildern 62 frei drehbar gelagert. Die beiden der Ablösewalze 88 benachbarten Umlenkrollen 114′ sind hingegen an einer um den Lagerschaft 100 schwenkbaren Führungswippe 116 angeordnet. Diese weist zwei zwischen den beiden Wippenschildern 96 und benachbart zu diesen angeordnete Führungsschilder 116′ auf, die über mit 118 bezeichneten Lagerhülsen am Lagerschaft 100 abgestützt sind. Die in Pfeilrichtung F gesehen der Ablösewalze 88 vorgelagerten Umlenkrollen 114′ sind an diesen Führungsschildern 116′ frei drehbar gelagert, wobei die obere dieser beiden Umlenkrollen 114′ derart angeordnet ist, dass das Endlosband 132 die Ablösewalze 88 um ungefähr 90 Grad umschliesst. Ungefähr unterhalb der Lagerwelle 94 ist an den Führungsschildern 116′ eine sich bis unterhalb die Wickelbandspule 76 erstreckende Führung 120 befestigt. Die Führung 120 ist zusammen mit der Führungswippe 116 derart gegen oben vorgespannt, dass die Führung mit einer an ihrem freien Endbereich frei drehbar gelagerten Rolle 122 den oberen Trum 112′ des Endlosbandes 112 an die Wickelbandspule 76 bzw. an das darauf aufgewickelte Wickelband 20 andrückt. Zu diesem Zweck stehen von der Führung 120 in Richtung gegen oben zwei Bolzen 124 ab, die an der Wippe 92 bei der Lagerwelle 94 befestigte Haltenasen 126 durchgreifen, und durch sich an den Haltenasen 126 abstützende Druckfedern 128 in Richtung gegen oben gezogen werden.Guide means 110 are provided between the detaching roller 88 and the winding tape spool 76 in order to bring the free end 82 of the winding tape 20 detached by means of the detaching roller 88 from the detaching roller 88 to the winding tape spool 76 and to guide the winding tape 20. An with its upper run 112 'the winding tape reel 76 with the detaching roller 88 under-connecting connecting endless belt 112 wraps partially around and is guided around pulleys 114 and 114'. The deflection rollers 114 provided adjacent to the winding tape reel 76 are freely rotatably mounted on the end shields 62. The two of the detaching roller 88 adjacent deflection rollers 114 ', however, are arranged on a pivoting about the bearing shaft 100 guide rocker 116. This has two between the two rocker plates 96 and adjacent to them arranged guide plates 116 ', which are supported by bearing sleeves designated 118 on the bearing shaft 100. The seen in the direction of arrow F. the detaching roller 88 upstream deflecting rollers 114 'are freely rotatably mounted on these guide plates 116', the upper of these two deflecting rollers 114 'being arranged such that the endless belt 132 encloses the detaching roller 88 by approximately 90 degrees. Approximately below the bearing shaft 94 is attached to the guide plates 116 'extending to below the winding tape spool 76 guide 120. The guide 120 is preloaded together with the guide rocker 116 such that the guide presses the upper run 112 'of the endless belt 112 against the winding tape reel 76 or onto the winding tape 20 wound thereon with a roller 122 which is freely rotatably mounted at its free end region. For this purpose, two bolts 124 protrude from the guide 120 in the upward direction, which pass through retaining lugs 126 fastened to the rocker 92 on the bearing shaft 94, and are drawn in the upward direction by compression springs 128 which are supported on the retaining lugs 126.

Ein Abschnitt dieser Führung 120 ist in der Figur 3 vergrössert und in der Figur 4 ein Querschnitt dargestellt. Von ihrem der Ablösewalze 88 zugewandten Ende bis in den Bereich unterhalb der Wickelbandspule 76 weist die Führung 120 eine plattenförmige Anordnung 130 auf, welche breiter ist als das Endlosband 112 und entlang welcher auf beiden Seiten je ein im Querschnitt ungefähr rechteckiges Hohlprofil 132 hochkannt verläuft. Die plattenförmige Anordnung 130 weist in der Mitte ein schmales und aussen zwei breite Rechteckprofile 134, 134′, vorzugsweise aus Aluminium, gleicher Höhe auf, wobei zwischen dem mittleren Rechteckprofil 134 und den beiden äusseren Rechteckprofilen 134′ je ein profilförmiger Permanentmagnet 136 vorgesehen ist. Die plattenförmige Anordnung 130 und die Hohlprofile 132 werden mittels diese in Querrichtung durchdringende Bolzen 138 zusammengehalten. Es ist zu beachten, dass die Hohlprofile 132 seitlich des Endlosbandes 112 über die plattenförmige Anordnung 130 vorstehen, um dieses und das darauf liegende Wickelband 20 zu führen. Im Bereich unterhalb der Wickelbandspule 76 weist die Führung 120 zwei Seitenplatten 140 auf, welche in bekannter Art und Weise an den Hohlprofilen 132 befestigt sind und an welchen die Rolle 122 frei drehbar gelagert ist. Die Seitenplatten 140 verlaufen auf beiden Seiten benachbart zur Wickelbandspule 76, sodass das auf diese aufzuwickelnde Wickelband 20 nicht seitlich wegteleskopieren kann.A section of this guide 120 is enlarged in FIG. 3 and a cross section is shown in FIG. From its end facing the detaching roller 88 to the area below the winding tape reel 76, the guide 120 has a plate-shaped arrangement 130 which is wider than the endless tape 112 and along which a hollow profile 132 of approximately rectangular cross section runs up on both sides. The plate-shaped arrangement 130 has in the middle a narrow and outside two wide rectangular profiles 134, 134 ', preferably made of aluminum, of the same height, a profile-shaped permanent magnet 136 being provided between the central rectangular profile 134 and the two outer rectangular profiles 134' is. The plate-shaped arrangement 130 and the hollow profiles 132 are held together by means of these bolts 138 which penetrate in the transverse direction. It should be noted that the hollow profiles 132 protrude laterally beyond the endless belt 112 over the plate-shaped arrangement 130 in order to guide this and the winding belt 20 lying thereon. In the area below the winding tape reel 76, the guide 120 has two side plates 140 which are fastened to the hollow profiles 132 in a known manner and on which the roller 122 is freely rotatably mounted. The side plates 140 run on both sides adjacent to the winding tape reel 76, so that the winding tape 20 to be wound on it cannot laterally telescope away.

Die Ablösewalze 88 und das Endlosband 112 bilden einen Förderspalt 142 für das Wickelband 20. An dem der Wickelbandspule 76 zugewandten-Ende dieses Förderspaltes 142 ist ein spatelförmiges Trennorgan 144 vorgesehen (Fig. 1), welches an den Führungsschildern 116′ befestigt ist und das durch den Förderspalt 142 in Richtung zur Wickelbandspule 76 umgelenkte freie Ende 82 des Wickelbandes 20 von der Ablösespule 88 löst, damit dieses auf dem oberen Trum 112′ des Endlosbandes 112 aufliegend zur Wickelbandspule 76 gefördert werden kann.The release roller 88 and the endless belt 112 form a conveyor gap 142 for the winding tape 20. At the end of this conveyor gap 142 facing the winding tape reel 76, a spatula-shaped separating element 144 is provided (FIG. 1), which is fastened to the guide plates 116 'and through the conveyor gap 142 in the direction of the winding tape spool 76 deflected free end 82 of the winding tape 20 from the release spool 88 so that it can be conveyed on the upper run 112 'of the endless belt 112 to the winding tape spool 76.

Das Wickelband 20 weist an seinem freien Endbereich einen Klettenreissverschluss auf, wie er beispielsweise aus der EP-A-0 310 784 bekannt ist, um das äussere Wickelbandende 82 zum Zusammenhalten des Wickels 21 am darunter liegenden Bereich des Wickelbandes 20 zu befestigen. Der Klettenreissverschluss beginnt dabei vorzugsweise vom freien Ende 82 des Wickelbandes 20 um einige Zentimeter beabstandet, um einen über den Klettenreissverschluss vorstehenden Lappen zu bilden. Im Bereich dieses Lappens und im daran anschliessenden Bereich des Klettenreissverschlusses sind im Wickelband 20 dünne, übereinanderliegende Weicheisenplättchen eingelassen, wie dies in der nachveröffentlichten CH-Patentanmeldung 00971/90-0 ausführlich beschrieben und gezeigt ist.The wrapping tape 20 has a Velcro zipper at its free end area, as is known, for example, from EP-A-0 310 784, in order to fasten the outer wrapping tape end 82 to hold the winding 21 together on the area of the wrapping tape 20 underneath. The Velcro zipper preferably begins at a distance of a few centimeters from the free end 82 of the winding tape 20. to form a tab projecting over the Velcro zipper. In the area of this flap and in the adjoining area of the Velcro zipper 20 thin, superimposed soft iron plates are embedded in the winding tape, as is described and shown in detail in the subsequently published CH patent application 00971 / 90-0.

Der Vollständigkeit halber sei noch erwähnt, dass der Förderbandanordnung 44 ein als Bandförderer ausgebildeter Zuförderer 146 vorgeschaltet ist, um die aufzuwickelnden Druckereiprodukte 19 der Aufwickeleinrichtung 10 zuzuführen.For the sake of completeness, it should also be mentioned that the conveyor belt arrangement 44 is preceded by a feed conveyor 146 designed as a belt conveyor in order to feed the printed products 19 to be wound onto the winding device 10.

Die Förderbänder 46 weisen auf ihrer Innenseite einen Führungswulst 46′′ auf, der zur seitlichen Führung der Förderbänder 46 in entsprechende Umfangsnuten 50′′ in den Walzen 50, 50′ eingreift. Die Förderbänder 46 werden mittels auf den unteren Trumen aufliegenden Gewichtswalzen 148 gespannt gehalten. Die Gewichtswalzen 148 sind über Schwenkarme 150 an der Traverse 64 schwenkbar gelagert.The conveyor belts 46 have on their inside a guide bead 46 '' which for lateral guidance of the conveyor belts 46 engages in corresponding circumferential grooves 50 '' in the rollers 50, 50 '. The conveyor belts 46 are held tensioned by means of weight rollers 148 resting on the lower runs. The weight rollers 148 are pivotally mounted on the crossmember 64 via swivel arms 150.

Die Funktionsweise der Aufwickeleinrichtung 10 wird nun anhand der Figuren 5-7 beschrieben. In diesen Figuren sind die für das Verständnis der Funktionsweise der Aufwickeleinrichtung 10 wesentlichen Teile dargestellt und mit gleichen Bezugszeichen wie in den Figuren 1-4 bezeichnet.The mode of operation of the winding device 10 will now be described with reference to FIGS. 5-7. In these figures, the parts essential for understanding the mode of operation of the winding device 10 are shown and designated by the same reference numerals as in FIGS. 1-4.

Um einen Wickelkern 18 an die Antriebsräder 28, 28′ der Lageranordnung 17 zur Anlage bringen zu können, wird die Lageranordnung 17 in eine Höhe verbracht, die dem in der Figur 5 strichpunktiert angedeuteten Wickelkern 18 entspricht. Bei angehobener Spannrolle 30 (siehe auch Figur 1) wird der Wickelkern 18 auf die Antriebsräder 28, 28′ abgelegt, und durch anschliessendes Absenken der Spannrolle 30 an diese angepresst. Die Förderbänder 46 der Förderbandanordnung 44 werden durch die Gewichtswalzen 148 gespannt gehalten. Die Wippe 92 ist im Gegenuhrzeigersinn in ihre obere Endlage verschwenkt in welcher die Nasen 96′ am Träger 42 anliegen. Das Endlosband 112 liegt an der Ablösewalze 88 und an der leeren Wickelbandspule 76 an. Auf den leeren Wickelkern 18 ist das Wickelband 20 als Wickelbandvorrat aufgewickelt und mittels des nicht gezeigten Klettenreissverschlusses verzurrt.In order to bring a winding core 18 to the drive wheels 28, 28 'of the bearing arrangement 17, the bearing arrangement 17 is brought to a height which corresponds to the winding core 18 indicated by dash-dotted lines in FIG. When the tensioning roller 30 is raised (see also FIG. 1), the winding core 18 is placed on the drive wheels 28, 28 'and pressed onto the tensioning roller 30 by subsequent lowering. The conveyor belts 46 of the conveyor belt arrangement 44 are held under tension by the weight rollers 148. The rocker 92 is pivoted counterclockwise into its upper end position in which the lugs 96 'rest on the carrier 42. The endless belt 112 abuts the detaching roller 88 and the empty winding reel 76. On the empty winding core 18, the winding tape 20 is wound up as a supply of winding tape and lashed by means of the Velcro zipper, not shown.

Anschliessend wird die Lageranordnung 17 wie mit dem Pfeil C in Figur 5 gezeigt, abgesenkt, sodass der Wickelkern 18 auf die oberen Trume 46′ der Förderbänder 46 zur Anlage kommt. Dieses Absenken der Lageranordnung 17 wird fortgesetzt, bis in eine untere in der Figur 6 gezeigte Endstellung, in welcher die Förderbänder 46 den Wickelkern 18 teilweise umschlingen. Durch Inbetriebsetzen des Antriebsmotores 34 wird der Wickelkern 18 entgegen der Aufwickelrichtung B in Pfeilrichtung D angetrieben. Durch die Umschlingung des Wickelkerns 18 durch die Förderbänder 46 werden diese im entsprechenden Umlaufsinn angetrieben, was zur Folge hat, dass die Wickelbandspule 76 im Aufspulsinn A dreht. Diese Drehung der Wickelbandspule 76 wird über das Endlosband 112 an die gegen das auf dem Wickelkern 18 aufgewickelte Wickelband 20 gepresste Ablösewalze 88 übertragen. Da der Durchmesser der Wickelbandspule 76 geringfügig grösser ist als der Durchmesser der Walzen 50′ dreht die Ablösewalze 88 mit geringfügig grösserer Umfangsgeschwindigkeit als der Wickelkern 18 bzw. das darauf aufgewickelte Wickelband 20. Sobald nun das freie Ende 82 des Wickelbandes 20 auf die Ablösespule 88 aufläuft, wird dieses, infolge der Anziehungskraft der Permanentmagnete 102 auf die im Endbereich des Wickelbandes 20 vorgesehenen Eisenplättchen, an diese gezogen, wodurch das freie Ende 82 vom auf den Wickelkern 18 aufgewickelten Wickelband 20 gelöst und unter Oeffnen des Klettenreissverschlusses in den Förderspalt 142 eingeführt wird. Beim Auslaufen aus dem Förderspalt 142 wird das freie Ende 82 des Wickelbandes 20 durch das Trennorgan 144 von dieser gelöst, sodass es auf den oberen Trum 112′ des Endlosbandes 112 aufliegend in Richtung gegen die Wickelbandspule 76 transportiert wird. Sobald nun das freie Ende 82 in den Bereich der Führung 120 gelangt, wird der Bereich des Wickelbandes 20 in welchem die Metallplättchen vorgesehen sind, durch die Wirkung der in der Führung 120 angeordneten Permanentmagnete 136 am Endlosband 112 festgehalten und mit diesem zur Wickelbandspule 76 verbracht. Mittels der an der Wickelbandspule 76 vorgesehenen Permanentmagnete 80 wird das freie Ende 82 des Wickelbandes 20 an die Wickelbandspule 76 gezogen um auf diese aufgewickelt zu werden. Der Wickelkern 18 wird in Pfeilrichtung D solange angetrieben, bis das gesamte Wickelband 20 bzw. die notwendige Länge dieses Wickelbandes 20 auf die Wickelbandspule 76 aufgespult ist, wie dies in der Figur 6 gezeigt ist. Der Unterschied der Umlaufgeschwindigkeit zwischen den Förderbändern 46 und der Umfangsgeschwindigkeit der Wickelbandspule 76 bzw. des darauf aufgewickelten Wickelbandes 20, sowie des gleich schnell umlaufenden Endlosbandes 112 wird durch die Rutschkupplungen 74 (Figur 2) aufgenommen. Das Wickelband 20 wird somit unter einer von diesen Rutschkupplungen 74 bestimmten Zugspannung auf die Wickelbandspule 76 aufgespult.The bearing arrangement 17 is then lowered, as shown by the arrow C in FIG. 5, so that the winding core 18 comes to rest on the upper runs 46 'of the conveyor belts 46. This lowering of the bearing arrangement 17 is continued until it reaches a lower end position shown in FIG. 6, in which the conveyor belts 46 partially wrap around the winding core 18. When the drive motor 34 is started up, the winding core 18 is driven in the direction of the arrow D in the opposite direction of the winding B. By wrapping the winding core 18 through the conveyor belts 46, these are driven in the corresponding direction of rotation, which has the consequence that the winding tape reel 76 rotates in the winding direction A. This rotation of the winding tape spool 76 is transmitted via the endless belt 112 to the detaching roller 88 pressed against the winding tape 20 wound on the winding core 18. Since the diameter of the winding tape reel 76 is slightly larger than the diameter of the rollers 50 ', the detaching roller 88 rotates at a slightly greater peripheral speed than the winding core 18 or the wound thereon Wrapping tape 20. As soon as the free end 82 of the winding tape 20 runs onto the release spool 88, this is pulled onto the iron plates provided in the end region of the winding tape 20 due to the attraction of the permanent magnets 102, causing the free end 82 from the winding core 18 wound winding tape 20 released and inserted into the conveyor gap 142 by opening the Velcro zipper. When running out of the conveyor gap 142, the free end 82 of the winding tape 20 is released from the separating element 144, so that it is transported lying on the upper run 112 'of the endless belt 112 in the direction against the winding tape reel 76. As soon as the free end 82 reaches the area of the guide 120, the area of the winding tape 20 in which the metal plates are provided is held by the action of the permanent magnets 136 arranged in the guide 120 on the endless tape 112 and brought with it to the winding tape reel 76. By means of the permanent magnets 80 provided on the winding tape reel 76, the free end 82 of the winding tape 20 is drawn to the winding tape reel 76 in order to be wound thereon. The winding core 18 is driven in the direction of the arrow D until the entire winding tape 20 or the necessary length of this winding tape 20 is wound onto the winding tape reel 76, as shown in FIG. 6. The difference in the rotational speed between the conveyor belts 46 and the circumferential speed of the winding belt reel 76 or the winding belt 20 wound thereon, as well as the endless belt 112 rotating at the same speed, is absorbed by the slip clutches 74 (FIG. 2). The winding tape 20 is thus under a tensile stress determined by these slip clutches 74 on the winding tape reel 76 spooled.

Anschliessend wird zum Aufwickeln der in Schuppenformation S und in Zuführrichtung F anfallenden Druckereiprodukte 19 der Wickelkern 18 durch Richtungsumkehr des Antriebsmotors 34 in Aufwickelrichtung B angetrieben (Figur 7). Durch die teilweise Umschlingung des Wickelkerns 18 angetrieben, laufen auch die Förderbänder 46 entgegen dem Aufspulsinn A in Pfeilrichtung A′ um. In dieser Drehrichtung sind die Hülsenfreiläufe 68 aktiv, sodass die Welle 58 (Figuren 1 und 2) von den Walzen 50′ entkoppelt ist. Die Welle 58 wird am Drehen in Pfeilrichtung A′ durch die Freiläufe 60 gehindert, sodass nun die Zugspannung im von der Wickelbandspule 76 abzuspulenden und zusammen mit den Druckereiprodukten 19 auf den Wickelkern 18 aufzuwickelnden Wickelbandes 20 durch die Wirkung der Bremsglieder 84 bestimmt ist. Sobald die gesamte Schuppenformation S zu einem Wickel 21 aufgewickelt ist, wird der Wickelkern 18 noch weiter angetrieben, bis das gesamte Wickelband 20 auf den Wickel 21 aufgewickelt ist. Dabei wird das freie Ende 82 des Wickelbandes 20 entgegen der Anzugskraft der Permantmagnete 80 von der Wickelbandspule 76 abgelöst und im Bereich der Führung 120 durch die Wirkung der Permanentmagnet 136 am Endlosband 112 gehalten. Nach dem Durchlaufen des Förderspaltes 142 wird der Kettenreissverschluss geschlossen indem die gegen den Wickel 21 vorgespannte Ablösewalze 88 das Wickelband 20 gegen die darunter liegende Windung des Wickelbandes 20 presst.Then, in order to wind up the printed products 19 occurring in scale formation S and in the feed direction F, the winding core 18 is driven by reversing the direction of the drive motor 34 in the winding direction B (FIG. 7). Driven by the partial wrap of the winding core 18, the conveyor belts 46 also run counter to the winding direction A in the direction of the arrow A '. In this direction of rotation, the sleeve freewheels 68 are active, so that the shaft 58 (FIGS. 1 and 2) is decoupled from the rollers 50 '. The shaft 58 is prevented from rotating in the direction of arrow A 'by the freewheels 60, so that the tension in the reel 76 to be unwound from the winding tape spool and together with the printed products 19 to be wound on the winding core 18 winding tape 20 is determined by the action of the brake members 84. As soon as the entire scale formation S has been wound up to form a winding 21, the winding core 18 is driven further until the entire winding band 20 is wound onto the winding 21. The free end 82 of the winding tape 20 is detached from the winding tape reel 76 against the pulling force of the permanent magnets 80 and held in the region of the guide 120 by the action of the permanent magnet 136 on the endless tape 112. After passing through the conveyor gap 142, the chain zipper is closed in that the release roller 88, which is biased against the winding 21, presses the winding tape 20 against the winding of the winding tape 20 underneath.

Zum Wegnehmen des fertigen Wickels 21 ab der Lageranordnung 17 wird diese in eine obere Endposition angehoben, sodass der Wickel 21 mit den oberen Trumen 46′ der Förderbänder 46 nicht mehr in Berührung steht. Durch Anheben der Spannrolle 30 wird nun der Wickelkern 18 freigegeben, sodass der Wickelkern 18 zusammen mit dem sich darauf befindenden Wickel 21, beispielsweise mittels eines Hubfahrzeuges, von der Lageranordnung 17 abgehoben werden kann.To remove the finished roll 21 from the bearing assembly 17, this is raised to an upper end position, so that the roll 21 with the upper runs 46 'of the conveyor belts 46 is no longer in contact. By lifting the tensioning roller 30, the winding core 18 is now released, so that the winding core 18 together with the winding 21 located thereon can be lifted off the bearing arrangement 17, for example by means of a lifting vehicle.

Die beschriebene Aufwickeleinrichtung 10 eignet sich insbesondere zum Herstellen von Wickeln 21 in kleinerer Grösse, d.h. dass das Verhältnis zwischen dem Aussendurchmesser des fertigen Wickels 21 zum Aussendurchmesser des Wickelkerns 18 etwa 3:1 oder kleiner ist. Es ist selbstverständlich auch denkbar, die Wickelbandspule beim Abspulen des Wickelbandes geregelt zu bremsen, sodass mit der Aufwickeleinrichtung auch Wickel mit einem grösseren Durchmesserverhältnis problemlos hergestellt werden können.The winding device 10 described is particularly suitable for producing coils 21 in a smaller size, i.e. that the ratio between the outside diameter of the finished winding 21 to the outside diameter of the winding core 18 is approximately 3: 1 or less. It is of course also conceivable to brake the winding tape reel in a controlled manner when unwinding the winding tape, so that the winding device can also be used to easily produce coils with a larger diameter ratio.

Die antriebsaktive Kopplung zwischen der Förderbandanordnung und der Wickelbandspule zum Aufspulen des Wickelbandes kann selbstverständlich auch anders als im Beispiel gezeigt ausgebildet sein. So könnten beispielsweise steuerbare Kopplungsglieder verwendet werden. Falls zum Aufspulen sowie Abspulen des Wickelbandes auf die bzw. ab der Wickelbandspule dieselben Zugspannungen im Wickelband erwünscht sind, wäre es auch möglich, nur eine einzige Rutschkupplung bzw. Bremseinrichtung vorzusehen.The driving coupling between the conveyor belt arrangement and the winding tape reel for winding the winding tape can of course also be designed differently than shown in the example. For example, controllable coupling elements could be used. If the same tensile stresses are desired in the winding tape for winding and unwinding the winding tape onto or from the winding tape reel, it would also be possible to provide only a single slip clutch or braking device.

Es ist auch denkbar, das Ablösen des freien Endes des Wickelbande vom Wickel mit andern als magnetischen Mitteln zu erzielen. So könnte die Umlenkeinrichtung eine Saug alze aufweisen, oder durch Adhäsion oder mit mechanischen Mitteln das freie Ende ablösen. In ähnlicher Art und Weise wäre es möglich, das Endlosband als Lochriemen auszubilden und zum Festhalten des freien Endes bzw. des Wickelbandes am Endlosband dieses im Bereich zwischen der Umlenkeinrichtung und der Wickelbandspule über einen mit einer Unterdruckquelle verbundenen Trog laufen zu lassen.It is also conceivable to achieve the detachment of the free end of the winding tape from the winding by means other than magnetic means. The deflection device could have a suction salt, or detach the free end by adhesion or mechanical means. In a similar way it would be possible to design the endless belt as a perforated belt and to hold the free end or the winding belt on the endless belt in the area between the deflection device and the winding belt reel by means of a trough connected to a vacuum source.
