Description

Die Erfindung betrifft eine Vorrichtung zum Auf- und Abwickeln von flachen Druckprodukten auf resp. von einem in einem Gestell angeordneten Wickelkern, dem zur Bildung von Wickellagen der Druckprodukte wenigstens ein von einem Wickeldorn abrollbares, dem Wickelkern unterschlächtig zugeführtes Wickelband zugeordnet ist.The invention relates to a device for winding and unwinding from flat printed products to resp. from one in a rack arranged winding core, to form winding layers the printed products have at least one rollable from a winding mandrel, winding tape fed underneath the winding core assigned.

In der Branche der Druckweiterverarbeitung sind solche Vorrichtungen unter der Bezeichnung PrintRoll-Systeme der Firmengruppe Müller Martini bekannt. Diese Vorrichtungen dienen der Forderung nach kürzeren Durchlaufzeiten beim Druck von Zeitschriften, Broschüren und anderen Druckprodukten bzw. einer geforderten hohen Produktionsleistung. Sie bilden auch den Schlüssel zu einer vollautomatischen Weiterverarbeitung. Solche Vorrichtungen lassen sich deshalb in Produktionslinien zum Sammelheften, Klebebinden, Fadenheften und Einstecken integrieren; sie können auch Schneidapparaten, Falz- und Adressiereinrichtung vor- oder nachgeschaltet werden. Such devices are in the print finishing industry under the name PrintRoll systems of the group of companies Muller Martini known. These devices serve the Demand for shorter lead times when printing magazines, Brochures and other printed products or one required high production output. They also form that Key to fully automatic processing. Such Devices can therefore be used in production lines Integrate saddle stitching, perfect binding, thread stitching and insertion; they can also cutters, folders and addressing devices upstream or downstream.

Beim PrintRoll-System wurde im Interesse einer wirtschaftlichen Anwendung darauf geachtet, dass das Gestell, der darin antreibbare Wickelkern und das Wickelband resp. das Bandmagazin eine hinsichtlich Benutzung untrennbare Einheit bilden, die jeweils mittels eines Hebemittels versetzbar ist resp. an verschiedenen Verarbeitungsstellen eingesetzt wird.The PrintRoll system was in the interest of an economic Application made sure that the frame that is in it drivable winding core and the winding tape respectively. the band magazine form an inseparable unit in terms of use, which can be moved by means of a lifting device respectively. on different processing points is used.

Neben dem PrintRoll-System existiert das Prinzip der Loslösung der Wickel resp. des Wickelkerns gemeinsam mit dem Wickelband von einem Gestell unter der Auffassung, dass eine Einheit, wie oben beschrieben, mit hohen Beschaffungskosten belastet ist, vermeintlich mehr Abstellraum in Anspruch nimmt. Eine trennbare Lösung, wo der Wickelkern dem Gestell entnommen werden kann, weist jedoch in der Anwendung verschiedene Unannehmlichkeiten bzw. Unsicherheiten auf. So ist u.a. keine produkteschonende Lagerung des Wickels gewährleistet, d.h. beschädigte Produkte führen zu Unterbrüchen bei der Verarbeitung; vor dem Aufwickeln der Produkte resp. dem Abwickeln muss das Wickelband am Wickelkern resp. am Wickeldorn des Bandmagazins eingespannt werden; teilweise gefüllte Wickel müssen von den überflüssigen Bandwicklungen vor dem Abwickeln der Produkte befreit werden und umgekehrt bedarf es überflüssiger Bandwicklungen vor dem Loslösen des Wickels vom Gestell; die Wickel sind beim Transport mit Lastwagen, Staplern oder anderen Transporteinrichtungen anfällig auf Beschädigungen.In addition to the PrintRoll system, there is the principle of detachment the wrap resp. of the winding core together with the winding tape from a rack considering that a unit like described above, is burdened with high procurement costs, supposedly takes more storage space. A separable Solution where the winding core is removed from the frame may, however, have various inconveniences in use or uncertainties. Among other things, no gentle on the product Storage of the winding guaranteed, i.e. damaged Products lead to interruptions in processing; before the Winding the products resp. the winding tape must be unwound at the winding core resp. clamped on the winding mandrel of the band magazine become; partially filled wraps must be of the superfluous Tape windings freed before unwinding the products and vice versa, unnecessary tape windings are required before detaching the wrap from the frame; the wraps are transported by truck, forklift or other Transport equipment prone to damage.

Aufgabe der Erfindung ist es daher, nebst den genannten Vorteilen des PrintRoll-Systems, dessen optimale Mobilität bei der Schaffung einer Vorrichtung der eingangs genannten Art zu erhalten und auf geringere Beschaffungskosten zu achten.The object of the invention is therefore, in addition to the advantages mentioned of the PrintRoll system, whose optimal mobility to create a device of the type mentioned received and to pay attention to lower procurement costs.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass Wikkelkern und Wickelbock einstückig verbunden antreibbar sind und der Wickeldorn des Wickelbandes in dem Wickelbock abnehmbar bzw. versetzbar gelagert ist.
Dadurch können die oben angeführten Bedürfnisse befriedigt und eine Vorrichtung zum Auf- und Abwickeln von flachen Druckprodukten geringeren Ausmasses und Konstruktionsgewichtes geschaffen werden.According to the invention, this object is achieved in that the winding core and winding frame can be driven in one piece and the winding mandrel of the winding tape is mounted in the winding frame in a removable or displaceable manner.
As a result, the above-mentioned needs can be met and a device for winding and unwinding flat printed products of smaller dimensions and construction weight can be created.

Bei einer einfachen Ausführungsform ist der Wickelbock aus zwei seitlich beabstandeten, den Wickelkern aufnehmenden Wangen gebildet.In a simple embodiment, the winding block is made of two laterally spaced cheeks receiving the winding core educated.

Dies erweist sich dann als besonders günstig, wenn die Wangen des Wickelbocks die Nabe des Wickelkerns bilden, d.h. wenn die Wangen sich an die Stirnseiten des Wickelkerns erstrecken und sich zum Drehantrieb des Wickelkerns anbieten.This proves to be particularly beneficial when the cheeks of the winding block form the hub of the winding core, i.e. if the Cheeks extend to the end faces of the winding core and lend themselves to the rotary drive of the winding core.

Vorteilhaft ist es, wenn der Wickelbock an dem oberen Halbmesser des zylindrischen Wickelkerns endet, sodass zweckmässig eine Verbindung von Wickelkern und Wickelbock durch Schweissen entstehen kann.It is advantageous if the winding block on the upper radius of the cylindrical winding core ends, so expedient a connection of the winding core and winding block by welding can arise.

Zur Belegung ungenutzter Räume im Wickelbock, empfiehlt es sich, dass das den Wickeldorn des Wickelbandes aufnehmende Lager im unteren Seitenbereich des Wickelbocks angeordnet ist, möglichst so, dass bei aufgerolltem Wickelband keine Berührung mit der Aufstellfläche bzw. dem Boden und dem Wickel erfolgt, wozu sich der Freiraum seitlich von der durch die Drehachse verlaufenden Vertikalebene eignet.It is recommended to occupy unused rooms in the winding block that the winding mandrel of the winding tape Bearing is arranged in the lower side area of the winding block, if possible, so that there is no contact when the winding tape is rolled up with the footprint or the floor and the wrap, which is why the free space to the side of that through the axis of rotation vertical plane is suitable.

Als einfach erweist sich eine Lagerung, die durch schlitzartige, einenends offene Ausnehmungen gebildet ist, die eine rasche Demontage des Wickeldorn bzw. des auf den Wickeldorn aufgerollten Wickelbandes gestatten. Storage, which is characterized by slit-like, recesses open at one end are formed, which are rapid Disassembly of the mandrel or the one rolled up on the mandrel Allow wrapping tape.

Zum Auf- oder Abwickeln der Druckprodukte ist das Anheben des Wickelbocks und -kerns bzw. der Vorrichtung vom Boden erforderlich, wozu der Wickelbock vorteilhaft einen Drehkupplungsteil einer zugeordneten Hebevorrichtung aufweist.To wind up or unwind the printed products, lift the Winding blocks and core or the device from the ground required, why the winding block advantageously a rotary coupling part has an associated lifting device.

Hierzu eignet sich u.a. ein Kupplungsteil einer Kupplungsvorrichtung, welcher in der Drehachse des Wickelkerns angeordnet und mit diesem bzw. der Nabe verbunden ist.Among other things, this is suitable a coupling part of a coupling device, which is arranged in the axis of rotation of the winding core and is connected to this or the hub.

Um die Vorrichtung beim Versetzen aus der Abwickel- in die Aufwickelposition und umgekehrt in einer bestimmten Lage halten oder verdrehen zu können, ist die Kupplungsvorrichtung vorzugsweise mit einer einschaltbaren Verdreharretierung ausgebildet.To move the device from the unwind to the Hold the winding position and vice versa in a certain position or to be able to twist is the coupling device preferably formed with a switchable twist lock.

Das Versetzen der Vorrichtung erfolgt zweckmässig mittels einer Hebevorrichtung, die seitlich des Wickelbocks angreifende, mittels eines Druckmediums betätigbare Schwenkarme aufweist.The device is expediently moved by means of a Lifting device, which engages on the side of the has swivel arms which can be actuated by means of a pressure medium.

Die vorgeschlagene Ausgestaltungsform der Vorrichtung gestattet einen Antrieb des Wickelkerns an dessen Wickelachse oder tangential am Umfang des Wickels.The proposed embodiment of the device allows a drive of the winding core on its winding axis or tangential to the circumference of the wrap.

Der Wickelbock ist zu seinem Transport auf dem Boden vorteilhaft mit einer dem Boden zugewendeten Transportvorrichtung bzw. einer Adaptervorrichtung ausgebildet.The winding block is advantageous for its transport on the floor with a transport device facing the ground or an adapter device.

Zur Aufnahme von grösseren Wickeln als vorgesehen, ist der Wickelbock an dem dem Boden zugewendeten Ende zur Verbindung mit einem unterstellbaren Sockel ausgebildet.To accommodate larger coils than intended, the Winding block at the end facing the floor for connection designed with a base that can be placed underneath.

Die Fig. 1 und 2 veranschaulichen eine Ausführungsform nach dem Prinzip der erfindungsgemässen Vorrichtung 1 zum rotativen Auf- und Abwickeln von flachen Druckprodukten auf resp. von einem Wickelkern 2, der in einem Wickelbock 3 angeordnet ist. Wickelkern 2 und Wickelbock 3 sind durch Schweissnähte einstückig miteinander verbunden, wobei gemäss Darstellung der Wickelkern 3 mit einem Teil seines Umfanges und an den seitlichen Rändern auf zwei seitlich beabstandeten Wangen 4 aufliegt. Zu diesem Zweck sind die Wangen 4 an dem oberen Ende etwa halbkreisförmig ausgenommen und ihre Seitenkanten 5, 6 verlaufen einerseits tangential an den Wickelkern 2 und andererseits die Standsicherheit des Wickelbocks 3 verbessernd, laufen die Seitenkanten 5, 6 zum Boden hin die Wangen 4 verbreiternd aus.
Bei einer alternativen Ausführungsform könnten die seitlichen Wangen 4 die Nabe 7 des Wickelkerns 2 bilden, wenn sie im oberen Bereich etwa dem nach oben sich erstreckenden Halbmesser des Wickelkerns 2 angepasst sind.1 and 2 illustrate an embodiment according to the principle of the device 1 according to the invention for the rotary winding and unwinding of flat printed products on resp. from a winding core 2, which is arranged in a winding block 3. The winding core 2 and the winding frame 3 are integrally connected to one another by welding seams, the winding core 3, according to the illustration, resting with part of its circumference and on the lateral edges on two laterally spaced cheeks 4. For this purpose, the cheeks 4 are recessed approximately semicircularly at the upper end and their side edges 5, 6 run tangentially to the winding core 2 on the one hand and, on the other hand, to improve the stability of the winding frame 3, the side edges 5, 6 widen the cheeks 4 towards the bottom .
In an alternative embodiment, the side cheeks 4 could form the hub 7 of the winding core 2 if they are adapted in the upper region approximately to the upwardly extending radius of the winding core 2.

Bei einer solchen Ausführungsform wäre der Wickelkern 2 zwischen den seitlichen Wangen 4 angeordnet und durch Schweissnähte mit letzteren verbunden.
In Fig. 1 ist weiterhin ein senkrecht verlaufendes, die Steifigkeit des Wickelbocks 3 und die Lagerung der Vorrichtung verbesserndes Verstärkungsblech 8 angedeutet. Die Kennnisse eines Fachmannes gestatten es, die Verbindung zwischen Wickelkern 2 und Wickelbock 3 durch andere bekannte Mittel herzustellen, wobei der Wickelkern 2 an den Stirnseiten wenigstens teilweise offen bleiben oder geschlossen ausgebildet sein kann.
Weiter erkennt man in den Fig. 1 und 2 die Anordnung eines Wickeldorns 9 für ein Wickelband 10, welches zur Bildung von Wickellagen aus Druckprodukten an dem Wickelkern 2 bestimmt ist, wobei das Wickelband 10, wie veranschaulicht, dem Wickelkern 2 bzw. dem zu bildenden Wickel aus Druckprodukten unterschlächtig zugeführt wird. Das Wickelband 10 ist an seinen Enden jeweils mit dem Wickeldorn 9 bzw. dem Wickelkern 2 verbunden und zwischen diesen beiden Organen gespannt. Diese Technik ist übrigens bekannt und das Spannen des Wickelbandes 10 kann auf verschiedene, zum Stand der Technik gehörende Arten erfolgen, so u.a. mittels einer auf den Wickeldorn 9 einwirkenden Antriebsvorrichtung, die hier weder näher beschrieben noch dargestellt ist.
Der Wickeldorn 9 ist in dem Wickelbock 3 bzw. in den Wangen 4 auf eine einfache Art lösbar gelagert, wozu gemäss Fig. 1 ein einseitig zugänglicher Führungsschlitz bzw. eine einseitig offene, schlitzförmige Ausnehmung 11 vorgesehen ist.
Der eine Welle 12 aufweisende Wickeldorn 9 kann beispielsweise in zwei auf die Wangen 4 verteilte Führungsschlitze eingeschoben, arretiert und wieder entfernt werden, wobei Sinn und Zweck im Zusammenhang mit Fig. 3 näher erläutert werden. Die Lagerung des Wickeldorns 9 im unteren Seitenbereich des Wikkelbocks 3 steht in Verbindung mit der Verwendungsweise der Vorrichtung 1 beim Auf- oder Abwickelvorgang, letzterer ist in Fig. 3 gezeichnet.
In den Fig. 1 und 2 ist ein aus Druckprodukten gebildeter Wikkel 13 durch strichpunktierte Linien vermerkt.
Zur Bildung grösserer Wickel 13 als vorgesehen, kann an dem Wickelbock 3 ein adaptierfähiger Sockel 14 unterstellt werden, der ebenso wie der Wickelbock 3 für den Tranport mit einer Aufnahmevorrichtung für einen Hubwagen, Hubstapler oder Kran, etc. ausgebildet ist.
Selbstverständlich kann auch wie gezeichnet, der Sockel 14 mit der Möglichkeit der besonderen Lagerung des Wickeldorns 9 ausgebildet sein.In such an embodiment, the winding core 2 would be arranged between the side cheeks 4 and connected to the latter by welding seams.
In FIG. 1, a vertical reinforcing plate 8 is also indicated, which improves the rigidity of the winding frame 3 and the mounting of the device. The knowledge of a person skilled in the art allows the connection between the winding core 2 and the winding frame 3 to be established by other known means, wherein the winding core 2 can remain at least partially open on the end faces or can be designed to be closed.
1 and 2 also show the arrangement of a winding mandrel 9 for a winding tape 10, which is intended to form winding layers of printed products on the winding core 2, the winding tape 10, as illustrated, the winding core 2 or the one to be formed Wrapped from printed products is undershot. The winding tape 10 is connected at its ends to the mandrel 9 or the winding core 2 and stretched between these two organs. Incidentally, this technique is known and the winding tape 10 can be tensioned in various ways belonging to the prior art, for example by means of a drive device acting on the winding mandrel 9, which is neither described nor shown here.
The winding mandrel 9 is detachably supported in the winding block 3 or in the cheeks 4 in a simple manner, for which purpose a guide slot accessible on one side or a slot-shaped recess 11 open on one side is provided.
The winding mandrel 9 having a shaft 12 can, for example, be pushed into two guide slots distributed on the cheeks 4, locked and removed again, the purpose of which being explained in more detail in connection with FIG. 3. The storage of the winding mandrel 9 in the lower side region of the winding bracket 3 is related to the use of the device 1 during the winding or unwinding process, the latter being shown in FIG. 3.
1 and 2, a winding 13 formed from printed products is noted by dash-dotted lines.
To form larger windings 13 than provided, an adaptable base 14 can be placed on the winding frame 3, which, like the winding frame 3 for transport, is designed with a receiving device for a pallet truck, forklift or crane, etc.
Of course, the base 14 can also be designed as shown with the possibility of special mounting of the winding mandrel 9.

Der Drehantrieb des Wickelkerns 2 bzw. der erfindungsgemässen Vorrichtung 1 auf deren Wickelachse 15 erfolgt nach dem Anheben der Vorrichtung 1 vom Boden, so dass die längste Seitenkante 5, 6 des Wickelbocks 3 frei über dem Boden drehen kann.The rotary drive of the winding core 2 or the inventive Device 1 on its winding axis 15 takes place after lifting the device 1 from the bottom so that the longest side edge 5, 6 of the winding block 3 can rotate freely above the floor.

Die insbesondere aus Wickelbock 3 und Wickelkern 2 gebildete Vorrichtung 1 kann mittels einer Hebevorrichtung 16 in eine hängende Lage versetzt werden, wobei in dieser Lage die Vorrichtung 1 in der Wickelachse 15 derart gefasst ist, dass ihre Drehbewegung erfolgen kann. Zu diesem Zweck weist die Vorrichtung 1 in der Wickelachse 15 einen Kupplungsteil 17 einer in der Zeichnung nicht vollständig gezeigten Drehverbindung auf, die es ermöglicht, die Vorrichtung 1 bzw. den Wickelkern 2 bspw. über die Nabe 7 in der hängenden Lage in Drehung versetzen zu können. Der andere Kupplungsteil könnte sodann in einer Hebevorrichtung 16 angeordnet sein. Damit die Vorrichtung 1 bedarfsweise in einer besonderen Drehlage gehalten werden kann, ist die Drehverbindung mit einer einschaltbaren Arretiervorrichtung ausgerüstet.
Die Fig. 3 und Fig. 4 zeigen eine doppelte Abwickelstation, in welcher die aus Druckprodukten gebildeten Wickel 13 in einer Vorrichtung 1, aus Wickelbock 3, Wickelkern 2 und Wickeldorn 9 sowie eingespanntem Wickelband 10 bestehend, mittels Handhubwagen 18 zum Abwickeln der Druckprodukte bereitgestellt sind.
Als erstes wird der Wickeldorn 9 mit dem restlichen Wickelband 10 aus dem Wickelbock 3 gehoben und in eine zum Abwickeln vorgesehene Betriebslage seitlich der Ruhelage im Wickelbock 3 versetzt, d.h. der Wickeldorn 9 wird in der Abwickelstation umgelagert.
Von der Annahme ausgehend, dass der Wickel 13 zur Verarbeitung bzw. Abwicklung der Druckprodukte auf eine grössere Höhe, als dass sie durch die Drehfreiheit der Vorrichtung 1 entsteht, angehoben werden muss, und dass der Wickeldorn 9 in die in
Fig. 3 gezeichnete Lage versetzt wird, ist es zur Verminderung der Steilheit der von den Wickeln 13 ablaufenden Wickelbänder 10 und zum förderwirksamen Anlegen eines Auslaufbandes 20 erforderlich, das/die Wickelbänder 10 um eine (erhöhte) Umlenkrolle 19 umzulenken, wie in Fig. 3 dargestellt. Wie Fig. 3 weiter zeigt, wird der Wickel 13 von einer durch Schwenkarme 21 gebildeten Hebevorrichtung 16, die durch Kolben-Zylinder-Einheiten 22 betrieben wird, angehoben und abgesenkt. Die freien Enden der Schwenkarme 21 greifen auf der Wickelachse 15 seitlich in die Vorrichtung 1 bzw. in die Nabe 7 des Wickelkerns 2 durch beispielsweise zapfenartige Fortsätze ein, wobei die Nabe 7 als Kupplungsteil 17 einer Drehverbindung ausgebildet ist.
Der Antrieb des Wickels 13 erfolgt von aussen mittels eines Tangentialantriebes 23; selbstverständlich wäre auch ein Zentralantrieb auf die Wickelachse 15 möglich, dessen Drehzahl in Abhängigkeit von der Änderung des Wickeldurchmessers für eine gleichmässige Abrollgeschwindigkeit zu steuern wäre. Der Wikkelbock 3 ist an dem dem Boden zugewendeten Ende durch eine Transportvorrichtung ausgebildet, die es erlaubt, die Vorrichtung 1 in leerem oder gewickeltem Zustand mit einem Hubwagen oder Stapler zu versetzen, auch wenn ein Sockel 14 unterstellt ist.The device 1, which is formed in particular from the winding frame 3 and the winding core 2, can be placed in a hanging position by means of a lifting device 16, in which position the device 1 is contained in the winding axis 15 in such a way that its rotational movement can take place. For this purpose, the device 1 in the winding axis 15 has a coupling part 17 of a rotary connection, which is not shown completely in the drawing, and which enables the device 1 or the winding core 2 to rotate, for example, via the hub 7 in the hanging position can. The other coupling part could then be arranged in a lifting device 16. So that the device 1 can be held in a special rotational position as required, the rotary connection is equipped with a lockable locking device.
FIGS. 3 and 4 show a double unwinding station, in which the windings 13 formed from printed products are provided in a device 1, consisting of winding head 3, winding core 2 and winding mandrel 9 and clamped winding band 10, by means of hand pallet trucks 18 for unwinding the printed products .
First, the winding mandrel 9 with the remaining winding tape 10 is lifted out of the winding frame 3 and placed in an operating position intended for unwinding to the side of the rest position in the winding frame 3, ie the winding mandrel 9 is transferred in the unwinding station.
Based on the assumption that the winding 13 for processing or unwinding the printed products must be raised to a greater height than that caused by the freedom of rotation of the device 1, and that the winding mandrel 9 into the
Fig. 3 drawn position is offset, it is necessary to reduce the steepness of the winding tapes 10 running from the coils 13 and for the promotional application of a discharge belt 20 to deflect the / the winding tapes 10 by a (raised) deflection roller 19, as in Fig. 3rd shown. 3 further shows, the winding 13 is raised and lowered by a lifting device 16, which is formed by swivel arms 21 and is operated by piston-cylinder units 22. The free ends of the swivel arms 21 engage laterally on the winding axis 15 in the device 1 or in the hub 7 of the winding core 2 by, for example, peg-like extensions, the hub 7 being designed as a coupling part 17 of a rotary connection.
The winding 13 is driven from the outside by means of a tangential drive 23; Of course, a central drive on the winding axis 15 would also be possible, the speed of which would have to be controlled as a function of the change in the winding diameter for a uniform unwinding speed. The trestle bracket 3 is formed at the end facing the floor by a transport device which allows the device 1 to be moved in an empty or wound state with a lifting truck or forklift, even if a base 14 is placed under it.
