Maschinen dieser Art, wie sie beispielsweise aus der WO 97/07979 hervorgehen, dienen zum Bedrucken oder sonstigen Dekorieren von über eine runde Außenkontur verfügenden Hohlkörpern wie Hülsen, Tuben, Dosen oder dergleichen. Unter dem Ausdruck "Dekorieren" sind dabei beispielsweise auch Maßnahmen zum Lackieren, Etikettieren, Folienprägen oder Siebdruck zu verstehen. Die betreffenden Maschinen verfügen über einen rotationsangetriebenen Spindelteller, der mit in Drehrichtung aufeinanderfolgend angeordneten Spindeleinheiten versehen ist, die über Aufnahmespindeln verfügen, an denen die Hohlkörper während des Dekorier- bzw. Bedruckvorganges gehalten werden. Benachbart zum Spindelteller ist eine ebenfalls rotationsangetriebene Dekorationstrommel vorgesehen, die peripher mit einer oder mehreren, meist segmentiert ausgebildeten Dekorationsflächen versehen ist - bei Druckmaschinen handelt es sich hier um Druckflächen - , welche sich bei der Rotation der Dekorationstrommel entlang einer kreisförmigen ersten Bahnkurve bewegen, die eine zwischen der Dekorationstrommel und dem Spindelteller befindliche Dekorationszone durchläuft.Machines of this kind, as they emerge, for example, from WO 97/07979, serve for printing or otherwise decorating hollow bodies having a round outer contour, such as sleeves, tubes, cans or the like. By the term "decorating" are meant, for example, measures for painting, labeling, foil stamping or screen printing. The machines in question have a rotation-driven spindle plate, which is provided with rotationally successively arranged spindle units which have receiving spindles on which the hollow bodies are held during the decorating or printing process. Adjacent to the spindle plate is also a rotation-driven decorative drum is provided, which is peripherally provided with one or more, usually segmented decorative surfaces - in printing machines are printing surfaces - which move during the rotation of the decorative drum along a circular first trajectory, the one passes between the decoration drum and the spindle plate located decoration zone.

Die an den Aufnahmespindeln fixierten Hohlkörper werden bei der Rotation des Spindeltellers ebenfalls durch die Dekorationszone hindurchgeschleußt. Dabei bewegen sich die radial nach außen orientieren Abschnitte der aufgesteckten Hohlkörper entlang einer zweiten Bahnkurve und werden in der Dekorationszone mit der dort gleichzeitig befindlichen Dekorationsfläche in Kontakt gebracht. Auf diese Weise kann beispielsweise ein Farbauftrag auf die Hohlkörper stattfinden.The fixed to the receiving spindles hollow body are also slewed through the decoration zone during rotation of the spindle plate. In this case, the radially outwardly oriented sections of the plugged-on hollow bodies move along a second trajectory and are brought into contact in the decoration zone with the decorative surface located there simultaneously. In this way, for example, an application of paint take place on the hollow body.

Da die beiden vorerwähnten Bahnkurven entgegengesetzt gekrümmt sind, bedarf es bei kontinuierlichen Dekorationsverfahren, die insbesondere im Hochgeschwindigkeitsbereich zur Anwendung gelangen, einer Bahnkorrektur der zweiten Bewegungsbahn, um deren Verlauf beim Durcheilen der Dekorationszone mit dem dortigen Verlauf der ersten Bahnkurve in Übereinstimmung zu bringen. Zu diesem Zweck sind gemäß WO 97/07979 die Spindeleinheiten durch mehrere Führungsstangen radial verschiebbar am Spindelteller geführt. Gleichzeitig stehen an einem Spindelträger der Spindeleinheiten gelagerte rollenförmige Kurvenfolgemittel mit einer Steuerkurve in Eingriff, die so geformt ist, dass die Spindeleinheiten beim Durchlaufen der Dekorationszone eine quer zu Drehachse des Spindeltellers gerichtete Nachführbewegung ausführen, die den Verlauf der zweiten Bahnkurve demjenigen der ersten Bahnkurve anpasst.Since the two above-mentioned trajectories are curved in the opposite direction, in continuous decoration processes, which are used in particular in the high-speed area, a trajectory correction of the second trajectory is required in order to bring their course when crossing the decoration zone into conformity with the course of the first trajectory. For this purpose, according to WO 97/07979, the spindle units are guided by a plurality of guide rods radially displaceable on the spindle plate. At the same time, roller-shaped cam followers mounted on a spindle carrier of the spindle units are engaged with a control cam which is shaped so that the spindle units, when passing through the decoration zone, execute a tracking movement directed transversely to the axis of rotation of the spindle plate, which adjusts the course of the second trajectory to that of the first trajectory.

Bei einer aus der DE-A-2408279 bekannten Maschine sind die Aufnahmespindeln exzentrisch ausgebildet und über einen seitlich versetzten Längenabschnitt drehbar am Spindelteller gelagert. Zur Vornahme einer Bahnkorrektur wird die betroffene Aufnahmespindel aufgrund des Zusammenwirkens eines Kurvenfolgers mit einer Steuerkurve verdreht, sodass ihr einen Hohlkörper tragender Längenabschnitt quer zur Drehachse des Spindeltellers verlagert wird. Um bei Bedarf ein radiales Abrücken einer Aufnahmespindel zu ermöglichen, sitzt die Aufnahmespindel exzentrisch in einer verdrehbaren Hohlwelle. Im Falle der US-A-3356019 wird die zur Bahnkorrektur dienende Nachführbewegung ebenfalls durch Verdrehen der exzentrischen Aufnahmespindeln erreicht.In a machine known from DE-A-2408279, the take-up spindles are formed eccentrically and rotatably mounted on the spindle plate via a laterally offset longitudinal section. To make a path correction, the affected receiving spindle is rotated due to the interaction of a cam follower with a control cam, so that her a hollow body-bearing longitudinal portion is displaced transversely to the axis of rotation of the spindle plate. If necessary, a radial departure To allow a receiving spindle, the receiving spindle sits eccentrically in a rotatable hollow shaft. In the case of US-A-3356019 the tracking correction serving tracking movement is also achieved by rotating the eccentric take-up spindles.

Ein Problem der bekannten Maschinen der eingangs genannten Art besteht im relativ hohen Verschleiß der für die Bahnkorrektur der Spindeleinheiten vorgesehenen Maßnahmen. Die bei einem Dekorationsvorgang auf die Aufnahmespindel eingeleiteten Kräfte bewirken ein Kippmoment, das die unmittelbar am Spindelträger angeordneten Kurvenfolgerollen verstärkt gegen die Steuerkurve presst. Außerdem wirken starke Biegemomente auf die Führungsstangen des Spindelträgers ein. Dies alles führt dazu, dass die Steuerungs- und Führungspräzision mit der Zeit abnimmt und somit die Qualität des Dekorationsvorganges leidet.A problem of the known machines of the type mentioned is the relatively high wear of the measures provided for the path correction of the spindle units. The introduced during a decorating process on the take-up spindle forces cause a tilting moment, which presses the arranged directly on the spindle carrier cam follower rollers reinforced against the control cam. In addition, strong bending moments act on the guide rods of the spindle carrier. All this means that the control and leadership precision decreases over time and thus suffers the quality of the decoration process.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Maschine der eingangs genannten Art zu schaffen, bei der die an der Bahnkorrektur beteiligten Komponenten weniger verschleißgefährdet sind.It is therefore an object of the present invention to provide a machine of the type mentioned, in which the components involved in the web correction are less prone to wear.

Zur Lösung dieser Aufgabe ist vorgesehen, dass die Bahnkorrekturmittel auf der der Drehachse des Spindeltellers zugewandten Innenseite einer jeweiligen Spindeleinheit mit Abstand zu dieser eine zur zugeordneten Aufnahmespindel parallele und bezüglich ihrer Längsachse drehbar gelagerte Schwenkwelle aufweisen, die mit radialem Abstand zu ihrer Längsachse die Kurvenfolgemittel trägt und an der, ebenfalls mit radialem Abstand zu ihrer Längsachse, eine andererseits an der Spindeleinheit angreifende Pleueleinrichtung angelenkt ist, wobei eine durch die Kurvenfolgemittel verursachte Drehbewegung der Schwenkwelle über die zwischengeschaltete Pleueleinrichtung die für die Bahnkorrektur verantwortliche Nachführbewegung der betreffenden Spindeleinheit hervorruft.To solve this problem, it is provided that the web correction means on the axis of rotation of the spindle plate facing inside of a respective spindle unit at a distance to this have a parallel to the associated receiving spindle and rotatably mounted with respect to its longitudinal axis pivot shaft, which carries the curve following means with radial distance to its longitudinal axis and on which, on the other hand, at a radial distance to its longitudinal axis, on the other hand, on the spindle unit engaging connecting rod means is articulated, wherein a rotation of the pivot shaft caused by the Kurvenfolgemittel via the intermediate connecting rod causes responsible for the web correction tracking movement of the respective spindle unit.

Die Bahnkorrektur der zweiten Bahnkurve beim Durchlaufen der Dekorationszone wird nun dadurch hervorgerufen, dass die Schwenkwelle um einen gewissen Drehwinkel verdreht wird, wobei das ausgeübte Drehmoment vom Abstand zwischen der Längsachse der Schwenkwelle und den an dieser angreifenden Kurvenfolgemittel abhängt. Die Drehbewegung der Schwenkwelle hat eine Verschwenken der Anlenkstelle der Pleueleinrichtung zur Folge, so dass letztere, je nach Drehrichtung, nach innen gezogen oder nach außen gedrückt wird, um dementsprechend die zugeordnete Spindeleinheit zum Erhalt der Nachführbewegung zu verschieben. Neben der hiermit erreichten hohen Präzision der Bahnkorrektur, stellt sich gleichzeitig der Effekt ein, daß die beim Dekoriervorgang in eine Aufnahmespindel eingeleiteten Kräfte nicht direkt auf die Kurvenfolgemittel und die diesen zugeordnete Steuerkurve einwirken, sondern zumindest größtenteils von der Schwenkwelle und deren Lagerung aufgenommen werden. Soweit durch die Dekorationskräfte über die Pleueleinrichtung ein Drehmoment auf die Schwenkwelle ausgeübt wird, kann durch geeignete Abstimmung der wirksamen Hebelarme erreicht werden, daß die die Kurvenfolgemittel gegen die Steuerkurve drückenden resultierenden Kräfte auf einem niedrigen Niveau liegen. Insgesamt kann somit der auftretende Verschleiß an den beweglichen Bestandteilen erheblich reduziert werden, was auch noch nach langer Betriebsdauer qualitativ hochwertige Dekorationsvorgänge ermöglicht.The path correction of the second trajectory when passing through the decoration zone is now caused by the fact that the pivot shaft is rotated by a certain angle of rotation, wherein the torque exerted depends on the distance between the longitudinal axis of the pivot shaft and acting on this curve follower. The rotational movement of the pivot shaft has a pivoting of the articulation point of the connecting rod result, so that the latter, depending on the direction of rotation, pulled inwards or pushed outwardly to accordingly move the associated spindle unit to obtain the tracking motion. In addition to the hereby achieved high precision of the orbit correction, at the same time has the effect that the introduced during the decorating process in a receiving spindle forces do not act directly on the Kurvenfolgemittel and the associated control cam, but are at least largely absorbed by the pivot shaft and its storage. As far as a torque is exerted on the pivot shaft by the decorative forces on the connecting rod, can be achieved by appropriate vote of the effective lever arms, that the Kurvenfolgemittel pressing against the control cam resulting forces are at a low level. Overall, thus, the occurring wear on the moving components can be significantly reduced, which even after a long period of operation allows high-quality decoration operations.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention will become apparent from the dependent claims.

Zweckmäßigerweise verfügt jede Spindeleinheit über einen die zugeordnete Aufnahmespindel tragenden Spindelträger, über den sie am Spindelteller gelagert ist. Dabei können die Aufnahmespindeln am zugehörigen Spindelteller drehbar gelagert sein, was beim Dekorationsvorgang eine Rotation um die eigene Achse ermöglicht und somit leichtgängige Drehbewegungen der aufgesteckten Hohlkörper auch dann gestattet, wenn zwischen diesen und den Aufnahmespindeln eine etwas größere Reibung auftritt. Vorzugsweise ist dabei jede Aufnahmespindel mit Drehantriebsmitteln versehen, mit denen sich beim Dekorationsvorgang eine Drehbewegung erzwingen läßt, was beispielsweise bei einem Bedruckvorgang eine sehr präzise Abwicklung des Druckbildes gestattet.Conveniently, each spindle unit has a spindle carrier supporting the associated take-up spindle, via which it is mounted on the spindle plate. The receiving spindles can be rotatably mounted on the associated spindle plate, which allows the decoration process, a rotation about its own axis and thus smooth rotational movements of the plugged hollow body also allowed when between these and the spindles a slightly greater friction occurs. Preferably, each receiving spindle with rotary drive means provided with which can force a rotational movement in the decorating process, which, for example, in a printing operation allows a very precise processing of the printed image.

Die bei der Erzeugung der Nachführbewegung mitwirkende Pleueleinrichtung enthält zweckmäßigerweise zumindest zwei und vorzugsweise genau zwei sich zwischen der Spindeleinheit und der Schwenkwelle erstreckende Pleuelarme, die in der Achsrichtung der Schwenkwelle zueinander beabstandet sind und insbesondere am vorderen und rückwärtigen Endbereich des gegebenenfalls vorhandenen Spindelträgers angreifen. Mit einer derartigen Parallelanordnung zweier Pleuelarme läßt sich eine sehr formstabile und führungsgenaue Lagerung erzielen. Die Pleuelarme können dabei jeweils Bestandteil einer eigenständigen Pleueleinheit sein.The cooperating in generating the Nachführbewegung connecting rod expediently contains at least two and preferably exactly two extending between the spindle unit and the pivot shaft connecting rods, which are spaced apart in the axial direction of the pivot shaft and attack in particular at the front and rear end portion of the optionally present spindle carrier. With such a parallel arrangement of two connecting rods can be a very dimensionally stable and accurate guidance storage achieve. The connecting arms can each be part of an independent connecting rod unit.

Bei einer bevorzugten Ausführungsform greifen die Pleueleinrichtungen an der jeweils zugeordneten Spindeleinheit in relativ zu dieser schwenkbeweglicher Weise bzw. gelenkig an, wobei die Schwenkachse zur Längsachse der Spindeleinheit parallel verläuft oder mit dieser zusammenfällt. Im letztgenannten Fall kann insbesondere vorgesehen sein, daß die Pleueleinrichtungen die zugeordnete Spindeleinheit schwenkbeweglich umschließen, was besonders kompakte Abmessungen zuläßt.In a preferred embodiment, the connecting rod devices engage with the respectively assigned spindle unit in relative to this pivotally movable or articulated manner, wherein the pivot axis runs parallel to or coincides with the longitudinal axis of the spindle unit. In the latter case, it may be provided in particular that the connecting rod devices pivotally surround the associated spindle unit, which permits particularly compact dimensions.

Eine weitere vorteilhafte Maßnahme besteht darin, die zur Ermöglichung der Nachführbewegung der Spindeleinheiten vorgesehenen Lagerungs- und Führungsmaßnahmen etwa auf Höhe der Längsachse der jeweiligen Aufnahmespindel vorzusehen, wobei jede Spindeleinheit in der Rotationsrichtung des Spindeltellers beidseits von am Spindelteller fixierten Lagerungseinheiten fixiert sein kann. Da hier die Führungsmaßnahmen praktisch auf gleicher Höhe wie die Einleitung der Dekorationskräfte stattfindet, ist eine sehr exakte Führung unter weitgehender Eliminierung von Kippkräften möglich. Desweiteren werden durch diese Maßnahme Vibrationen wirksam unterdrückt.A further advantageous measure is to provide the provision for enabling the tracking movement of the spindle units storage and management measures approximately at the level of the longitudinal axis of the respective receiving spindle, wherein Each spindle unit can be fixed in the direction of rotation of the spindle plate on both sides of storage units fixed to the spindle plate. Since the management measures take place here practically at the same level as the initiation of the decoration forces, a very precise guidance is possible with a substantial elimination of tilting forces. Furthermore, vibrations are effectively suppressed by this measure.

Bei einer qualitativ noch hochwertigeren Ausstattung kann die Maschine zusätzlich mit Abrückungsmitteln ausgestattet sein, durch die die Aufnahmespindeln aus ihrer normalerweise eingenommenen Grundstellung vorübergehend radial nach innen in eine abgerückte Stellung verlagert werden können, so daß die zweite Bahnkurve beim Durchlaufen der Dekorationszone zur ersten Bahnkurve beabstandet ist. Dies ermöglicht ein individuelles Abrücken der Aufnahmespindeln von der Dekorationstrommel, wenn aufgrund einer Störung oder einer sonstigen Ursache die betreffende Aufnahmespindel nicht oder nicht korrekt mit einem Hohlkörper bestückt ist. Ohne Abrückung bestünde die Gefahr, daß der Dekorationsvorgang an der unbestückten Aufnahmespindel ausgeführt würde. Durch das vorübergehende Abrücken kann ein ausreichend großer Abstand herbeigeführt werden, um eine Berührung zwischen der Dekorationstrommel und einer Aufnahmespindel zu vermeiden.In a qualitatively even higher quality equipment, the machine may additionally be equipped with Abrückungsmitteln, by which the take-up spindles can be temporarily moved radially outwardly from their normally occupied initial position to a withdrawn position, so that the second trajectory is spaced when passing through the decoration zone to the first trajectory , This allows an individual retraction of the take-up spindles of the decorative drum, if due to a fault or other cause, the recording spindle in question is not or not correctly equipped with a hollow body. Without disengagement there would be a risk that the decoration process would be performed on the bare spindle recording. By temporarily moving away a sufficiently large distance can be brought about to avoid contact between the decorative drum and a receiving spindle.

Zweckmäßigerweise wird die von den Abrückungsmitteln erzeugte Abrückungsbewegung von den Spindeleinheiten als ganzes ausgeführt. Während im Falle der WO 97/07979 durch ein kurzzeitiges Verdrehen der exzentrisch gelagerten Aufnahmespindeln nur diese Aufnahmespindeln allein abgerückt werden, was einen gesonderten Abrückungsantrieb erfordert, können bei der Neuerung Bestandteile der Bahnkorrekturmittel auch zum Abrücken der Aufnahmespindeln eingesetzt werden.Conveniently, the Abrückungsbewegung generated by the Abrückungsmitteln is carried out by the spindle units as a whole. While in the case of WO 97/07979 only a short time twisting of the eccentrically mounted take-up spindles, these take-up spindles are moved away, resulting in a separate Abrückungsantrieb requires, in the innovation components of the web correction means can also be used to move the take-up spindles.

Dabei wird die Abrückungsbewegung der Aufnahmespindeln zweckmäßigerweise durch eine radiale Verlagerung der Schwenkwelle hervorgerufen. Die Abrückungsmittel können für jede Spindeleinheit ein am Spindelteller um eine zur Längsachse der zugeordneten Aufnahmespindel parallele Drehachse drehbar gelagertes Abrückungsteil enthalten, an dem die zugeordnete Schwenkwelle mit paralleler Drehachse exzentrisch drehgelagert ist. Zusätzlich vorgesehene Betätigungsmittel können dabei ein Verdrehen des Abrückungsteils relativ zum Spindelteller und zur zugeordneten Schwenkwelle hervorrufen, um das Abrückungsteil in zwei unterschiedlichen Drehstellungen zu positionieren, in denen die Schwenkwelle unterschiedlich weit von der Drehachse des Spindeltellers beabstandet ist.The Abrückungsbewegung the receiving spindles is advantageously caused by a radial displacement of the pivot shaft. The disengagement means may comprise, for each spindle unit, a disengagement part rotatably mounted on the spindle plate about a rotation axis parallel to the longitudinal axis of the associated take-up spindle and on which the associated swivel shaft with eccentric rotation axis is rotatably mounted. Additionally provided actuating means may cause a rotation of the Abrückungsteils relative to the spindle plate and the associated pivot shaft to position the Abrückungsteil in two different rotational positions in which the pivot shaft is spaced differently far from the axis of rotation of the spindle plate.

Eine besonders kompakte Bauweise und eine geringe zu bewegende Masse ergibt sich, wenn das Abrückungsteil jeweils hohlwellenartig ausgebildet ist und die Schwenkwelle zumindest teilweise umschließt.A particularly compact design and a low mass to be moved results when the Abrückungsteil each has a hollow shaft-like and encloses the pivot shaft at least partially.

Die Drehstellungen des Abrückungsteils können durch Federmittel fixiert sein, wobei ein Schnappmechanismus zum Einsatz kommen kann, welcher bewirkt, daß ein und dieselben Federmittel beide Drehstellungen festhalten können.The rotational positions of the Abrückungsteils may be fixed by spring means, wherein a snap mechanism may be used, which causes one and the same spring means can hold both rotational positions.

Um das Abrückungsteil in eine die abgerückte Stellung der zugeordneten Aufnahmespindel hervorrufende Drehposition zu verbringen, kann ein Auslöser vorhanden sein, der durch eine Sensoreinrichtung aktiviert wird, welche den Bestückungszustand der Aufnahmespindeln vor dem Erreichen der Dekorationszone erfaßt.To the Abrückungsteil in a the retracted position of the associated receiving spindle causing rotating position spend, there may be a trigger, which is activated by a sensor device which detects the mounting state of the take-up spindles before reaching the decoration zone.

Die Beschreibung des Ausführungsbeispiels orientiert sich an einem für eine Druckmaschine typischen Aufbau, wobei die erfindungsrelevanten Maßnahmen wie erwähnt auch bei für andere Dekorationsmaßnahmen dienenden Maschinen realisierbar sind, beispielsweise bei Maschinen zum Lackieren, Etikettieren, Folienprägen oder Siebdruck.The description of the embodiment is based on a construction typical for a printing machine, wherein the measures relevant to the invention as mentioned can also be implemented in machines serving for other decoration measures, for example in machines for painting, labeling, foil stamping or screen printing.

Die Figur 1 zeigt einen Ausschnitt einer Druckmaschine, welche eine Zufuhr-Fördereinrichtung 1 und eine Abfuhr-Fördereinrichtung 2 enthält, die dem peripheren Bereich eines rotationsangetriebenen Spindeltellers 3 zugeordnet sind. Mit der Zufuhr-Fördereinrichtung 1 können zu bedruckende Hohlkörper 4 dem Spindelteller 3 zugeführt werden. Durch die Abfuhr-Fördereinrichtung 2 werden bereits bedruckte Hohlkörper 4 vom Spindelteller 3 übernommen und abtransportiert.FIG. 1 shows a section of a printing machine which contains a feed conveyor 1 and a discharge conveyor 2 which are assigned to the peripheral area of a rotation-driven spindle plate 3. With the feed conveyor 1 to be printed hollow body 4 can be supplied to the spindle plate 3. By the discharge conveyor 2 already printed hollow body 4 are taken from the spindle plate 3 and transported away.

Der Spindelteller 3 ist im Betrieb zu einer Rotationsbewegung um eine Drehachse 5 mit einer durch Pfeil angedeuteten Spindelteller-Drehrichtung 6 antreibbar. Er ist mit einer Mehrzahl in der Spindelteller-Drehrichtung 6 aufeinanderfolgend angeordneten Spindeleinheiten 7 ausgestattet, die jeweils eine Aufnahmespindel 8 mit zur Drehachse 6 paralleler Spindelachse 11 enthalten.The spindle plate 3 is in operation for a rotational movement about a rotation axis 5 with a direction indicated by arrow spindle plate rotation 6 drivable. It is equipped with a plurality of spindle units 7 arranged in succession in the spindle-disk rotating direction 6, each of which contains a receiving spindle 8 with a spindle axis 11 parallel to the axis of rotation 6.

Jede Spindeleinheit 7 verfügt dabei über einen am teller- oder scheibenförmigen Grundkörper 9 des Spindeltellers 3 gelagerten Spindelträger 10, der die zugeordnete Aufnahmespindel 8 trägt, die mit einem Lagerabschnitt 14 im Innern des Spindelträgers 10 drehbar gelagert ist und mit einem Aufnahmeabschnitt 15 an der Vorderseite des Spindelträgers 10 herausragt.Each spindle unit 7 has a plate or disc-shaped base body 9 of the spindle plate 3 mounted spindle carrier 10, which carries the associated receiving spindle 8, which is rotatably mounted with a bearing portion 14 in the interior of the spindle carrier 10 and a receiving portion 15 protrudes at the front of the spindle carrier 10.

Auf die Aufnahmeabschnitte 15 können zu bedruckende oder in sonstiger Weise zu dekorierende Hohlkörper 4 lösbar aufgesteckt werden. Das Aufstecken geschieht durch die mit geeigneten Übergabemitteln ausgestattete Zufuhr-Fördereinrichtung 1. In vergleichbarer Weise erfolgt die Entnahme bereits bedruckter Hohlkörper 4 durch die Abfuhr-Fördereinrichtung 2.On the receiving portions 15 to be printed or in any other way to be decorated hollow body 4 are releasably attached. The plugging takes place by means of the supply conveyor 1 equipped with suitable transfer means. The removal of already printed hollow bodies 4 by the discharge conveyor 2 takes place in a comparable manner.

Zur Fixierung des auf einem Aufnahmeabschnitt 15 sitzenden Hohlkörpers 4 können einer jeweiligen Aufnahmespindel 8 geeignete Haltemittel 16 zugeordnet sein, beispielsweise auf magnetischer Basis oder auf Unterdruckbasis arbeitende Haltemittel 16. Letzteres ist beim Ausführungsbeispiel der Fall, wo die Aufnahmespindel 8 einen stirnseitig ausmündenden Unterdruckkanal besitzt, der an eine nicht näher dargestellte Unterdruckquelle angeschlossen ist, um den aufgesteckten Hohlkörper 4 durch Vakuum festzuhalten.For fixing the seated on a receiving portion 15 the hollow body 4 8 suitable holding means 16 may be associated with a respective receiving spindle, for example, on a magnetic basis or vacuum-based holding means 16. The latter is in the embodiment of the case where the receiving spindle 8 has a front side opening out vacuum channel, the is connected to a vacuum source, not shown, to hold the plugged hollow body 4 by vacuum.

In bezüglich der Drehachse 5 rechtwinkeliger Richtung versetzt, befindet sich in der Nachbarschaft des Spindeltellers 3 eine ebenfalls motorisch rotationsangetriebene Dekorationstrommel 17. Ihre Drehachse 18 verläuft parallel und mit Abstand zur Drehachse 5 des Spindeltellers 3, wobei die Anordnung so getroffen ist, daß sich die Dekorationstrommel 17 und der Spindelteller 3 peripher ein Stück weit seitlich überlappen. Auf diese Weise wird erreicht, daß umfangsseitig an der Mantelfläche der Dekorationstrommel 17 angeordnete Dekorationsflächen 19 - beim Ausführungsbeispiel von Druckflächen gebildet - auf gleicher axialer Höhe wie die Aufnahmeabschnitte 15 der Aufnahmespindeln 8 zu liegen kommen. Die durch Pfeil angedeutete Drehrichtung 6' der Dekorationstrommel ist derjenigen (6) des Spindeltellers 3 entgegengesetzt.Offset in relation to the axis of rotation 5 rectangular direction, is located in the vicinity of the spindle plate 3 is also a motor-driven rotation drum decoration 17. Its axis of rotation 18 is parallel and spaced from the axis of rotation 5 of the spindle plate 3, wherein the arrangement is made such that the decoration drum 17 and the spindle plate 3 peripherally overlap a bit far laterally. In this way it is achieved that peripherally arranged on the lateral surface of the decorative drum 17 decorative surfaces 19 - formed in the embodiment of printing surfaces - At the same axial height as the receiving portions 15 of the take-up spindles 8 come to rest. The direction of rotation indicated by arrow 6 'of the decorative drum is opposite to that (6) of the spindle plate 3.

Im Betrieb der Maschine durchlaufen die Dekorationsflächen 19 eine durch die Rotation der Dekorationstrommel 17 bedingte kreisförmige erste Bahnkurve 20. In einer dem Übergangsbereich zwischen dem Spindelteller 3 und der Dekorationstrommel 17 zugeordneten Dekorationszone 21 - auf diese konzentrieren sich die Abbildungen der Figuren 3 bis 7 - laufen die Dekorationsflächen 19 am Außenumfang 24 des jeweils gleichzeitig die Dekorationszone 21 durchlaufenden Hohlkörper 4 ab und nehmen an diesem die gewünschte Dekorierung vor, beim Ausführungsbeispiel einen Aufdruck.During operation of the machine, the decorative surfaces 19 pass through a circular first trajectory 20 caused by the rotation of the decorative drum 17. In a transition zone between the spindle plate 3 and the decorative drum 17 associated decoration zone 21 - concentrate on the figures of Figures 3 to 7 - run the decorative surfaces 19 on the outer circumference 24 of each simultaneously passing through the decoration zone 21 hollow body 4 and take on this the desired decoration, in the embodiment a print.

Die einzelnen Dekorationsflächen 19 werden von einer am Umfang der Dekorationstrommel 17 angeordneten Auftragseinrichtung 25 mit dem Dekorationsmaterial versehen, wobei die Auftragseinrichtung 25 beim Ausführungsbeispiel ein Farbwerk ist und das Dekorationsmaterial aus Druckfarbe besteht. Letztere wird dann in der Dekorationszone 21 auf den Außenumfang der kreiszylindrischen Hohlkörper 4 aufgedruckt.The individual decorative surfaces 19 are provided by a arranged on the periphery of the decorative drum 17 applicator 25 with the decoration material, the applicator 25 in the embodiment is an inking and the decorative material is made of ink. The latter is then printed in the decoration zone 21 on the outer circumference of the circular cylindrical hollow body 4.

Anstelle mehrerer, segmentartig über den Trommelumfang verteilter Dekorationsflächen 19 könnte auch eine einzige, ununterbrochen umlaufende Dekorationsfläche vorgesehen sein.Instead of several, segmentally distributed over the drum circumference decoration surfaces 19 and a single, continuous circumferential decorative surface could be provided.

Die Maschine ist für kontinuierlichen Dekorationsvorgang ausgelegt, wobei sowohl die Dekorationstrommel 17 als auch der Spindelteller 3 ständig rotieren. Dabei durchlaufen die radial nach außen orientierten Abschnitte 26 der auf die Aufnahmespindeln 8 aufgesteckten Hohlkörper 4 eine zweite Bahnkurve 27. Ohne besondere Maßnahmen hätte diese zweite Bahnkurve 27 beim Durchlaufen der Dekorationszone 21 wie die erste Bahnkurve 20 einen kreisförmigen Verlauf, jedoch mit entgegengesetzter Krümmung. Damit jedoch zur Durchführung eines kontinuierlichen Dekorationsvorganges über eine längere Wegstrecke hinweg ein Berührkontakt zwischen dem Außenumfang 24 der Hohlkörper 4 und den Dekorationsflächen 19 möglich ist, ist die Anordnung so getroffen, daß sich die beiden Bahnkurven 20, 27 bei kreisförmigem Verlauf überschneiden würden, wobei Bahnkorrekturmittel 28 vorhanden sind, die dafür sorgen, daß der Verlauf der zweiten Bahnkurve 27 beim Passieren der Dekorationszone 21 mit dem Verlauf der ersten Bahnkurve 20 übereinstimmt.The machine is designed for continuous decoration process, with both the decorative drum 17 and the Rotate spindle plate 3 constantly. The radially outwardly oriented portions 26 of the plugged onto the spindles 8 hollow body 4 through a second trajectory 27 without special measures would have this second trajectory 27 when passing through the decoration zone 21 as the first trajectory 20 a circular course, but with opposite curvature. However, in order to carry out a continuous decoration process over a longer distance away contact between the outer periphery 24 of the hollow body 4 and the decorative surfaces 19 is possible, the arrangement is such that the two trajectories 20, 27 would overlap in a circular course, wherein Bahnkorrekturmittel 28 are present, which ensure that the course of the second trajectory 27 when passing the decoration zone 21 coincides with the course of the first trajectory 20.

Die Bahnkorrektur wird dadurch erreicht, daß die Spindeleinheiten 7 bei mit gleichzeitigem Dekorationsvorgang erfolgendem Durchlaufen der Dekorationszone 21 zu einer durch Doppelpfeil markierten Nachführbewegung 29 angetrieben werden, die quer und insbesondere rechtwinkelig zur Drehachse 5 des Spindeltellers 3 gerichtet ist, so daß die betreffende Aufnahmespindel 8, und mit ihr der daran fixierte Hohlkörper 4, eine der Umlaufbewegung um die Drehachse 5 überlagerte Radialbewegung bezüglich dieser Drehachse 5 ausführen, und zwar derart, daß praktisch die Krümmung der ersten Bahnkurve 20 nachgefahren wird.The path correction is achieved in that the spindle units 7 are driven at simultaneous decoration process passing through the decoration zone 21 to a marked by double arrow Nachführbewegung 29 which is directed transversely and in particular perpendicular to the axis of rotation 5 of the spindle plate 3, so that the respective take-up spindle 8, and with it the hollow body 4 fixed thereto, perform a radial movement with respect to this axis of rotation 5 superimposed on the rotational movement about the rotational axis 5, in such a way that virtually the curvature of the first trajectory 20 is traced.

Aufgrund der leichtgängigen Drehlagerung der Aufnahmespindeln 8 können die Hohlkörper 4 dabei an der Dekorationsfläche 9 abrollen. Es ist ferner möglich, den Aufnahmespindeln 8 wie beim Ausführungsbeispiel Drehantriebsmittel 31 zuzuordnen, durch die aktiv eine Rotation um die Spindelachse 11 erzwungen werden kann, zumindest während des Hindurchlaufens durch die Dekorationszone 21.Due to the smooth pivotal mounting of the take-up spindles 8, the hollow body 4 can roll on the decorative surface 9. It is also possible to associate the take-up spindles 8, as in the embodiment, with rotary drive means 31, by which rotation about the spindle axis 11 can be actively forced, at least during passage through the decoration zone 21.

Um die Nachführbewegung 29 zu ermöglichen, sind die Spindeleinheiten 7 etwa auf Höhe der Spindelachse 11 in Richtung der Nachführbewegung 9 verschiebbar geführt. Die hierzu vorgesehenen Führungsmittel 32 enthalten beim Ausführungsbeispiel pro Spindeleinheit 7 zwei in der Rotationsrichtung 6 des Spindeltellers 3 zueinander beabstandete und dabei den Spindelträger 10 auf entgegengesetzten Seiten flankierende Lagerungseinheiten 33, die am Grundkörper 9 des Spindeltellers 3 festgelegt sind. Diese definieren an den einander zugewandten Seiten radial verlaufende Führungsflächen, an denen der zwischengefügte Spindelträger 10 bezüglich der Drehachse 5 radial verschiebbar anliegt.In order to enable the tracking movement 29, the spindle units 7 are displaceably guided approximately at the height of the spindle axis 11 in the direction of the tracking movement 9. The guide means 32 provided for this purpose contain in the exemplary embodiment per spindle unit 7 two mutually spaced apart in the direction of rotation 6 of the spindle plate 3 while the spindle carrier 10 flanking on opposite sides of storage units 33 which are fixed to the base body 9 of the spindle plate 3. These define on the mutually facing sides radially extending guide surfaces on which the interposed spindle carrier 10 is radially displaceable relative to the axis of rotation 5.

Zugunsten einer kompakten Bauweise sind die Lagerungseinheiten 33 beim Ausführungsbeispiel jeweils gleichzeitig auf entgegengesetzten Seiten mit Führungsflächen versehen, so daß sie zur gleichzeitigen Führung zweier benachbarter Spindelträger 10 dienen können. Die Anordnung ist so getroffen, daß Spindelträger 10 und Lagerungseinheiten 33 in der Drehrichtung 6 abwechselnd angeordnet sind.For the sake of a compact construction, the bearing units 33 in the embodiment are each provided at the same time on opposite sides with guide surfaces, so that they can serve for the simultaneous guidance of two adjacent spindle carriers 10. The arrangement is such that spindle carrier 10 and bearing units 33 are arranged alternately in the direction of rotation 6.

Die Bahnkorrekturmittel 28 enthalten für jede Spindeleinheit 7 eine auf deren der Drehachse 5 des Spindeltellers 3 zugewandten Innenseite plazierte Schwenkwelle 34. Bezogen auf die Drehachse 5 liegt sie bevorzugt mit Abstand radial innerhalb des zugeordneten Spindelträgers 10, wobei sie parallel zur zugeordneten Aufnahmespindel 8 verläuft und um ihre Längsachse 35 bezüglich dem Grundkörper 9 des Spindeltellers 3 drehbar ist.The web correction means 28 contain for each spindle unit 7 on which the rotation axis 5 of the spindle plate 3 facing inside placed pivot shaft 34. Relative to the axis of rotation 5, it is preferably at a distance radially within the associated spindle carrier 10, wherein it is parallel to the associated receiving spindle 8 and to its longitudinal axis 35 with respect to the base body 9 of the spindle plate 3 is rotatable.

Mit radialem Abstand "a" zu der Längsachse 35 ist an der Schwenkwelle 34 eine Pleueleinrichtung 36 angelenkt, die beim Ausführungsbeispiel aus zwei eigenständigen Pleueleinheiten 37a, 37b besteht. Jede dieser Pleueleinheiten 37a, 37b verfügt über einen Pleuelarm 38a, 38b, der einenends mit dem schon erwähnten radialen Abstand "a" an einer Anlenkstelle 43 gelenkig mit der Schwenkwelle 34 verbunden ist. Die jeweilige Anlenkstelle 43 kann durch eine Bolzenlagerung definiert werden, wobei die Gelenkachse 44 parallel zur Längsachse 35 der Schwenkwelle 34 verläuft.With a radial distance "a" to the longitudinal axis 35, a connecting rod device 36 is articulated on the pivot shaft 34, which consists in the embodiment of two separate connecting rod units 37a, 37b. Each of these connecting rod units 37a, 37b has a connecting rod arm 38a, 38b, which is connected at one end with the already mentioned radial distance "a" at an articulation point 43 to the pivot shaft 34 in an articulated manner. The respective pivot point 43 can be defined by a pin bearing, wherein the hinge axis 44 extends parallel to the longitudinal axis 35 of the pivot shaft 34.

Um die Abbildung übersichtlicher zu gestalten, ist der Bereich der Anlenkstellen 43 in Figur 2 übertrieben auseinandergezogen dargestellt. In der Praxis wird der radiale Abstand "a" regelmäßig relativ gering ausfallen, wie dies die Figur 3 illustriert, wobei die Anlenkstelle 43 durchaus auch zumindest partiell radial innerhalb des Außenumfanges der Schwenkwelle 34 liegen kann.In order to make the illustration clearer, the region of the articulation points 43 in FIG. 2 are exaggeratedly drawn apart. In practice, the radial distance "a" will regularly be relatively low, as illustrated in Figure 3, wherein the pivot point 43 may well be at least partially radially within the outer periphery of the pivot shaft 34.

An dem der Anlenkstelle 43 entgegengesetzten Ende ist jeder Pleuelarm 38 an der Spindeleinheit 7, relativ zu dieser schwenkbeweglich, gelagert. Die dabei definierte Schwenkachse 44 könnte prinzipiell parallel und beabstandet zur Spindelachse 11 verlaufen und sich beispielsweise auf der der Schwenkwelle 34 zugewandten Innenseite der Aufnahmespindel 8 befinden. Um besonders kompakte Abmessungen zu erzielen, ist die Anordnung beim Ausführungsbeispiel jedoch so getroffen, daß die Schwenkachse 44 mit der Längsachse der Spindeleinheit 7 bzw. mit der Spindelachse 11 zusammenfällt. Dies wird vorzugsweise dadurch realisiert, daß jede Pleueleinheit 37a, 37b am äußeren Ende ihres Pleuelarmes 38a, 38b einen den Spindelträger 10 koaxial umschließenden Lagerring 45 besitzt. Dieser hat eine kreisförmige Innenkontur, wobei die Außenfläche des Spindelträgers 10 im zugeordneten Bereich ebenfalls kreisförmig konturiert ist. Die Auslegung ist so getroffen, daß jede Pleueleinheit 37a, 37b relativ zur Spindelachse 11 verschwenkbar ist, wobei sich der Lagerring 45 um den lediglich in Richtung der Nachführbewegung 29 verstellbaren Spindelträger 10 dreht.At the pivot point 43 opposite end of each Pleuelarm 38 on the spindle unit 7, relative to this pivotable, stored. The thereby defined pivot axis 44 could in principle be parallel and spaced from the spindle axis 11 and, for example, on the pivot shaft 34 facing inside of the receiving spindle 8 are. In order to achieve particularly compact dimensions, the arrangement in the embodiment, however, is such that the pivot axis 44 coincides with the longitudinal axis of the spindle unit 7 and with the spindle axis 11. This is preferably realized in that each connecting rod unit 37a, 37b has at the outer end of its connecting rod arm 38a, 38b a bearing ring 45 surrounding the spindle carrier 10 coaxially. This has a circular inner contour, wherein the outer surface of the spindle carrier 10 is also contoured circular in the associated area. The design is such that each connecting rod 37a, 37b is pivotable relative to the spindle axis 11, wherein the bearing ring 45 rotates about the only adjustable in the direction of the tracking movement 29 spindle carrier 10.

Die beiden Pleueleinheiten 37a, 37b bzw. deren Pleuelarme 38a, 38b sind in der Achsrichtung der Schwenkwelle 34 zweckmäßigerweise so beabstandet zueinander angeordnet, daß sie am vorderen und rückwärtigen Endbereich des Spindelträgers 10 angreifen. Dadurch werden die Spindeleinheiten 7 sehr formstabil gegenüber der Schwenkwelle 34 abgestützt.The two connecting rod units 37a, 37b or their connecting rod arms 38a, 38b are expediently arranged in the axial direction of the pivoting shaft 34 at a distance from one another such that they engage the front and rear end areas of the spindle carrier 10. As a result, the spindle units 7 are supported in a very dimensionally stable manner with respect to the pivot shaft 34.

Von der Schwenkwelle 34 ragt radial ein Tragarm 46 weg, der drehfest mit der Schwenkwelle 34 verbunden ist. Er befindet sich zweckmäßigerweise an einem axialen Endbereich der Schwenkwelle 34, und dabei insbesondere an deren rückseitigem Ende, das der von der Dekorationszone 21 abgewandten Rückseite des Grundkörpers 9 des Spindeltellers 3 zugeordnet ist.From the pivot shaft 34 projects radially a support arm 46 which is rotatably connected to the pivot shaft 34. It is expediently located at an axial end region of the pivot shaft 34, and in particular at the rear side thereof End, which is assigned to the remote from the decoration zone 21 back of the main body 9 of the spindle plate 3.

An diesem Tragarm 26 sind, mit einem radialen Abstand "b" zur Längsachse 35 der Schwenkwelle 34, Kurvenfolgemittel 47 angeordnet, die vorzugsweise von Wälz- bzw. Rollkörpern gebildet sind, welche am Tragarm 46 mit zur Achsrichtung der Schwenkwelle 34 paralleler Drehachse drehbar gelagert sind.On this support arm 26, with a radial distance "b" to the longitudinal axis 35 of the pivot shaft 34, curve following means 47 are arranged, which are preferably formed by rolling or rolling bodies which are rotatably mounted on the support arm 46 with the axis of rotation of the pivot shaft 34 parallel axis of rotation ,

Die Kurvenfolgemittel 47 wirken mit einer beim Ausführungsbeispiel von einer Steuernut gebildeten ortsfesten Steuerkurve 48 zusammen, die an einem geeigneten Steuerkurventräger 49 vorgesehen ist, welcher beim Ausführungsbeispiel der Rückseite des Grundkörpers 9 beabstandet gegenüberliegt. Bei der Rotation des Spindeltellers 3 laufen die den einzelnen Schwenkwellen 34 zugeordneten Kurvenfolgemittel 47 an der Steuerkurve 48 entlang, die im Bereich der Dekorationszone 21 einen von der Kreisform abweichenden, zur Drehachse 5 hin ausgeknickten Verlauf 50 hat.The Kurvenfolgemittel 47 cooperate with a formed in the embodiment of a cam groove fixed cam 48 which is provided on a suitable cam carrier 49, which in the embodiment of the rear side of the main body 9 is spaced. During the rotation of the spindle plate 3, the cam followers 47 associated with the individual pivot shafts 34 run along the control cam 48, which has a profile 50 deviating from the circular shape in the region of the decoration zone and bent towards the axis of rotation 5.

Der ausgeknickte Verlauf 50 ist auf die Krümmung der ersten Bahnkurve 20 abgestimmt. Solange sich bei der Rotation des Spindeltellers 3 die Kurvenfolgemittel 47 in dem kreisförmig gekrümmten Bereich der Steuerkurve 48 befinden, bleibt die Radialposition der Spindeleinheiten 7 bezüglich dem Grundkörper 9 konstant. Diese Betriebsphase ist in Figur 4 angedeutet. Sobald jedoch die Kurvenfolgemittel 47 in den Steuerkurvenabschnitt mit ausgeknicktem Verlauf 50 eintreten, werden sie dem Kurvenverlauf entsprechend radial verlagert, was aufgrund des radialen Abstandes "b" zur Längsachse der Schwenkwelle 34 ein Verschwenken derselben um die besagte Längsachse 35 zur Folge hat. Die daraus resultierende Drehposition der Schwenkwelle 34 ist in Figur 5 gezeigt, wo durch Pfeil 53 auch die Schwenkrichtung angedeutet ist.The bent path 50 is matched to the curvature of the first trajectory 20. As long as during the rotation of the spindle plate 3, the curve following means 47 are in the circularly curved region of the control cam 48, the radial position of the spindle units 7 with respect to the base body 9 remains constant. This operating phase is indicated in FIG. However, as soon as the curve following means 47 enter the cam section 50 with a bent-over profile 50, they are displaced radially in accordance with the curve, which is due to the radial distance "b" to the longitudinal axis of the pivot shaft 34 has a pivoting thereof about the said longitudinal axis 35 result. The resulting rotational position of the pivot shaft 34 is shown in Figure 5, where indicated by arrow 53, the pivoting direction.

Die Drehbewegung der Schwenkwelle 34 hat zur Folge, daß die Anlenkstellen 43 für die Pleuelarme 38a, 38b ebenfalls verschwenkt und radial nach innen in Richtung zur Drehachse 5 des Spindeltellers verlagert werden. Dementsprechend werden die Pleuelarme 38a, 38b und mit diesen die mit ihnen verbundene Spindeleinheit 7 gemäß Pfeil 54 in Figur 5 nach radial innen verlagert.The rotational movement of the pivot shaft 34 has the consequence that the articulation points 43 for the connecting rod arms 38a, 38b also pivoted and displaced radially inwardly in the direction of the axis of rotation 5 of the spindle plate. Accordingly, the connecting rod arms 38a, 38b and with them the associated spindle unit 7 according to arrow 54 in Figure 5 are moved radially inward.

Dem ausgeknickten Verlauf 50 entsprechend wird jede Spindeleinheit 7 beim Durchlaufen der Dekorationszone 21 von der Pleueleinrichtung 36 zunächst nach innen gezogen und anschließend wieder nach außen gedrückt, so daß der der Dekorationszone 21 zugeordnete Bahnabschnitt 55 der zweiten Bahnkurve 27 einen mit der ersten Bahnkurve 20 übereinstimmenden Verlauf hat.Corresponding to the bent path 50, each spindle unit 7 is first drawn inwardly through the decorative zone 21 by the connecting rod 36 and then pressed outwards again, so that the decoration zone 21 associated track section 55 of the second trajectory 27 coincides with the first trajectory 20 course Has.

Während eines Dekorationsvorganges werden in die Aufnahmespindeln 8 bzw. die Spindeleinheiten 7 hohe Kräfte eingeleitet, die die Spindeleinheiten 7 in der Pfeilrichtung 54 beaufschlagen. Diese Kräfte bewirken über die kniegelenkartige Verbindung zwischen Pleueleinrichtung 36 und Schwenkwelle 34 an letzterer ein Drehmoment, das schließlich auch auf den Kontaktbereich zwischen den Kurvenfolgemitteln 47 und der Steuerkurve 48 übertragen wird. Da jedoch der radiale Abstand "a" wesentlich kleiner gewählt ist als der radiale Abstand "b", ergibt sich ein günstiges Hebelverhältnis, aus dem nurmehr geringe Anpreßkräfte zwischen den Kurvenfolgemitteln 47 und der Steuerkurve 48 resultieren. Dadurch ist der Verschleiß stark reduziert. Außerdem ergibt sich durch die Parallelanordnung der beiden Pleueleinheiten 37a, 37b in Verbindung mit dem Spindelträger 10 und der Schwenkwelle 34 eine rahmenähnliche Konstruktion, die eine sehr formstabile und führungsgenaue Lagerung gewährleistet.During a decoration process, high forces are introduced into the take-up spindles 8 or the spindle units 7, which act on the spindle units 7 in the direction of the arrow 54. These forces bring about the knee-joint connection between the connecting rod 36 and pivot shaft 34 to the latter a torque that is finally transmitted to the contact area between the Kurvenfolgemitteln 47 and the control cam 48. However, since the radial distance "a" is chosen to be much smaller than the radial distance "B", there is a favorable lever ratio, resulting in the only low contact forces between the Kurvenfolgemitteln 47 and the control cam 48. As a result, the wear is greatly reduced. In addition, results from the parallel arrangement of the two connecting rod units 37a, 37b in conjunction with the spindle carrier 10 and the pivot shaft 34, a frame-like construction, which ensures a very dimensionally stable and accurate guidance storage.

Zusätzlich zu den Bahnkorrekturmitteln 28 verfügt die Maschine vorzugsweise zusätzlich über Abrückungsmittel 56, die in der Lage sind, jede einzelne Spindeleinheit 7 und somit die zu dieser gehörende Aufnahmespindel 8 individuell vorübergehend aus ihrer Grundstellung in eine aus Figuren 6 und 7 hervorgehende abgerückte Stellung zu verlagern. Dabei ist unter Grundstellung diejenige Stellung der Spindeleinheiten 7 zu verstehen, die diese beim Durchlaufen der zweiten Bahnkurve 27 einnehmen. Die abgerückte Stellung zeichnet sich dadurch aus, daß die Spindeleinheiten 7 bezüglich der zweiten Bahnkurve 27 in Richtung zur Drehachse 5 des Spindeltellers 3 radial verlagert sind, so daß die radial nach außen orientierten Abschnitte 26 der aufgesteckten Hohlkörper 4, sofern vorhanden, eine modifizierte zweite Bahnkurve 57 durchlaufen, die zum eigentlichen Verlauf der zweiten Bahnkurve 27 und somit auch zu ersten Bahnkurve 20 um ein vorgegebenes Maß "c" beabstandet ist. Allerdings wird dieser Abrückungsvorgang normalerweise nur dann durchgeführt, wenn eine Aufnahmespindel 8 nicht oder inkorrekt mit einem Hohlkörper 4 bestückt ist. Zur Erfassung des Bestückungszustandes sind Sensormittel 58 vorgesehen, beispielsweise induktive Näherungssensoren, welche den Abrückungsvorgang auslösen, wenn aufgrund des ermittelten Zustandes kein Dekorationsvorgang hinsichtlich der betreffenden Spindeleinheit 7 ausgeführt werden soll. Die Aufnahmespindel 8 wird dann soweit von der Dekorationstrommel 17 abgerückt, daß ein Kontakt mit den Dekorationsflächen 19 ausgeschlossen ist und die Aufnahmespindel 8 nicht verschmutzt wird.In addition to the web correction means 28, the machine preferably additionally has release means 56 which are capable of individually displacing each individual spindle unit 7 and thus the associated take-up spindle 8 temporarily from its home position to a raised position resulting from Figs. In this case, the position of the spindle units 7 is to be understood by the basic position, which they occupy when passing through the second trajectory 27. The withdrawn position is characterized in that the spindle units 7 are radially displaced with respect to the second trajectory 27 in the direction of the axis of rotation 5 of the spindle plate 3, so that the radially outwardly oriented portions 26 of the plugged hollow body 4, if present, a modified second trajectory 57 through which the actual course of the second trajectory 27 and thus also to the first trajectory 20 by a predetermined amount "c" is spaced. However, this Abrückungsvorgang is usually carried out only when a receiving spindle 8 is not or incorrectly equipped with a hollow body 4. For detecting the mounting state, sensor means 58 are provided, for example inductive proximity sensors, which trigger the Abrückungsvorgang when due to the determined condition no decoration process with respect to the respective spindle unit 7 is to be executed. The take-up spindle 8 is then moved away from the decoration drum 17 so far that contact with the decorative surfaces 19 is excluded and the receiving spindle 8 is not contaminated.

Die Sensormittel 58 befinden sich zweckmäßigerweise an einer Stelle, die der Dekorationszone 21 entgegen der Drehrichtung 6 ein Stück weit vorgelagert ist und dort im Bereich neben der zweiten Bahnkurve 27 liegt. Somit bleibt ausreichend Zeit, um exakt die gewünschte Spindeleinheit 7 beim Durchlaufen der Dekorationszone 21 zielgerichtet abzurücken. Hat die betreffende Spindeleinheit 7 die Dekorationszone 21 passiert, kann sie durch entgegengesetzten Bewegungsablauf wieder in die Grundstellung eingerückt werden.The sensor means 58 are expediently located at a location which is upstream of the decoration zone 21 counter to the direction of rotation 6 and lies there in the area adjacent to the second trajectory 27. Thus, there is sufficient time to move exactly the desired spindle unit 7 when passing through the decoration zone 21 targeted. If the relevant spindle unit 7 has passed the decoration zone 21, it can be retracted into the basic position by an opposite movement sequence.

Beim Ausführungsbeispiel ist von Vorteil, daß die von den Abrückungsmitteln 56 erzeugte Abrückungsbewegung von den Spindeleinheiten 7 jeweils als ganzes ausgeführt wird. Dadurch können zur Erzeugung des Bewegungsablaufes Bestandteile der Bahnkorrekturmittel 28 herangezogen werden, was eine Einsparung von Bauvolumen und Kosten bewirkt.In the embodiment, it is advantageous that the Abrückungsbewegung generated by the Abrückungsmitteln 56 is performed by the spindle units 7 in each case as a whole. As a result, components of the path correction means 28 can be used to generate the movement sequence, which results in a saving of construction volume and costs.

So wird die Abrückungsbewegung der Spindeleinheiten 7 beim Ausführungsbeispiel durch eine radiale Verlagerung der Schwenkwelle 34 hervorgerufen. Die Abrückungsbewegung wird dabei der für die Bahnkorrektur verantwortlichen Drehbewegung der Schwenkwelle 34 überlagert.Thus, the Abrückungsbewegung the spindle units 7 in the embodiment caused by a radial displacement of the pivot shaft 34. The Abrückungsbewegung is superimposed on the responsible for the orbit correction rotational movement of the pivot shaft 34.

Konkret enthalten die Abrückungsmittel 56 beim Ausführungsbeispiel ein die Schwenkwelle 34 hohlwellenartig zumindest teilweise und vorzugsweise vollständig umschließendes Abrükkungsteil 59. Jeder Spindeleinheit 7 ist ein solches Abrükkungsteil 59 zugeordnet, das am Grundkörper 9 des Spindeltellers 3 drehbar gelagert ist, wobei die Drehachse 62 mit seiner Längsachse zusammenfällt und sich parallel zur Längsachse 35 der Schwenkwelle 34 erstreckt. Letztere ist nun in dem Abrückungsteil 59 drehgelagert, so daß ihre Drehlagerung bezüglich des Grundkörpers 9 mittelbar unter Zwischenschaltung des Abrückungsteils 59 erfolgt. Dabei ist die Schwenkwelle 34 exzentrisch am Abrückungsteil 59 drehgelagert, so daß ihre Längsachse 35 mit Abstand parallel zur Drehachse 62 des Abrückungsteils 58 verläuft.Specifically, the Abrückungsmittel 56 in the embodiment, the pivot shaft 34 at least partially hollow shaft and at least partially enclosing Abrükkungsteil 59. Each spindle unit 7 is assigned such a Abrükkungsteil 59 which is rotatably mounted on the base body 9 of the spindle plate 3, wherein the axis of rotation 62 coincides with its longitudinal axis and extends parallel to the longitudinal axis 35 of the pivot shaft 34. The latter is now rotatably mounted in the Abrückungsteil 59, so that their pivotal bearing with respect to the base body 9 indirectly takes place with the interposition of the Abrückungsteils 59. In this case, the pivot shaft 34 is eccentrically rotatably mounted on the Abrückungsteil 59, so that its longitudinal axis 35 extends at a distance parallel to the axis of rotation 62 of the Abrückungsteils 58.

Die oben in Verbindung mit der Bahnkorrektur erläuterte Drehbewegung der Schwenkwelle 34 findet somit relativ zu dem am Grundkörper 9 gelagerten Abrückungsteil 59 statt.The above-explained in connection with the path correction rotational movement of the pivot shaft 34 thus takes place relative to the mounted on the base body 9 Abrückungsteil 59.

Die Abrückungsmittel 56 enthalten desweiteren Betätigungsmittel 63, die ein Verdrehen des Abrückungsteils 59 um seine Drehachse 62 relativ zum Grundkörper 9 des Spindeltellers 3 und zur zugeordneten Schwenkwelle 34 hervorrufen können. Dabei kann das Abrückungsteil 59 wahlweise in einer von zwei Drehstellungen positioniert werden, die als Abrück-Drehstellung 64 und als Einrück-Drehstellung 65 bezeichnet seien und aus Figuren 6 und 7 hervorgehen. Bedingt durch die exzentrische Lagerung der Schwenkwelle 34 am Abrückungsteil 59, nimmt die Schwenkwelle 34 in den beiden Drehstellungen 64, 65 des Abrückungsteils 59 unterschiedliche Radialpositionen bezüglich der Drehachse 5 ein. In der Einrück-Drehstellung 65 hat sie ihre Normalposition, in der Abrück-Drehstellung 64 ist sie näher zur Drehachse 5 verlagert, und mit ihr die über die Pleueleinrichtung 56 angelenkte Spindeleinheit 7.The Abrückungsmittel 56 further include actuating means 63 which can cause a rotation of the Abrückstesteils 59 about its axis of rotation 62 relative to the base body 9 of the spindle plate 3 and the associated pivot shaft 34. In this case, the Abrückungsteil 59 can be selectively positioned in one of two rotational positions, which are referred to as Abrück-rotational position 64 and as engagement-turning position 65 and emerge from Figures 6 and 7. Due to the eccentric mounting of the pivot shaft 34 on the Abrückungsteil 59, the pivot shaft 34 takes in the two rotational positions 64, 65th of the Abrückungssteils 59 different radial positions with respect to the axis of rotation 5 a. In the engagement rotational position 65, it has its normal position, in the disengaging rotational position 64, it is moved closer to the axis of rotation 5, and with it the articulated about the connecting rod 56 spindle unit. 7

Die Betätigungsmittel 63 beinhalten einen durch die Sensormittel 58 gesteuert umschaltbaren Auslöser 66. Er kann mit einem drehfest mit dem Abrückungsteil 59 verbundenen, zugleich aber mit radialem Abstand zu dessen Drehachse 62 angeordneten ersten Anschlag 67 zusammenarbeiten. In der in Figuren 5 und 6 mit gestrichelten Linien dargestellten unwirksamen Stellung 68 des Auslösers 66, der ortsfest und dabei vorzugsweise am Steuerkurventräger 49 angeordnet ist, kann der Spindelteller 3 bei in Einrück-Drehstellung 65 befindlichem Abrückungsteil 59 rotieren, ohne daß der Auslöser 66 auf den ersten Anschlag 67 einwirken würde. Die Bewegungsbahn des ersten Anschlages 67 läuft an dem die unwirksame Stellung 68 einnehmenden Auslöser 66 vorbei.The actuating means 63 include a controlled by the sensor means 58 switchable trigger 66. It can cooperate with a non-rotatably connected to the Abrückungsteil 59, but at the same time arranged at a radial distance from the axis of rotation 62 first stop 67. In the illustrated in Figures 5 and 6 with dashed lines inoperative position 68 of the trigger 66, which is stationary and preferably arranged on the cam carrier 49, the spindle plate 3 can rotate at in engaging rotary position 65 Abrückungsteil 59 without the trigger 66 on the first stop 67 would act. The path of movement of the first stop 67 runs past the trigger 66 occupying the inoperative position 68.

Veranlaßt durch die Sensormittel 58 kann der Auslöser 66 jedoch in eine in der Zeichnung in durchgezogenen Linien abgebildete wirksame Stellung 69 bewegt werden, insbesondere durch eine Schwenkbewegung, in der er in die Bewegungsbahn des ersten Anschlages 67 ragt, wenn das zugeordnete Abrükkungsteil 59 die Einrück-Drehstellung 65 einnimmt. Somit trifft der erste Anschlag 67 auf den Auslöser 66 auf und wird in die Abrück-Drehstellung 64 verdreht, die aus Figuren 6 und 7 hervorgeht.Triggered by the sensor means 58, however, the trigger 66 can be moved into an effective position 69 shown in solid lines in the drawing, in particular by a pivoting movement in which it projects into the path of movement of the first stop 67, if the associated removal part 59 blocks the engagement. Rotary position 65 occupies. Thus, the first abutment 67 strikes the trigger 66 and is rotated to the Abrück-Drehstellung 64, which is apparent from Figures 6 and 7.

Die damit verbundene abgerückte Stellung der zugeordneten Spindeleinheit 7 wird beibehalten, bis nach dem Durchlaufen der Dekorationszone 21 ein ebenfalls zu den Betätigungsmitteln 63 zählender Rücksteller 72 wirksam wird. Dieser ragt bei die Abrück-Drehstellung 64 einnehmendem Abrückungsteil 59 in die Bewegungsbahn eines zweiten Anschlages 73, der wie der erste Anschlag 67 mit radialem Abstand zur Drehachse des Abrückungsteils 59 angeordnet ist. Als Folge wird das Abrükkungsteil 59 wieder in die Einrück-Drehstellung 65 zurückgedreht.The associated withdrawn position of the associated spindle unit 7 is maintained until, after passing through the decoration zone 21, a return actuator 72, which likewise counts toward the actuating means 63, becomes effective. This protrudes at the Abrück-rotational position 64 engaging Abrückungsteil 59 in the path of movement of a second stop 73, which is like the first stop 67 arranged at a radial distance from the axis of rotation of the Abrückungsteils 59. As a result, the Abrükkungsteil 59 is rotated back into the engagement rotational position 65.

Die Figuren 6 und 7 zeigen die abgerückte Stellung einer Spindeleinheit 7 mit in Abrück-Drehstellung 64 befindlichem Abrückungsteil 59. Dabei ist in Figur 7 eine Phase dargestellt, bei der die Dekorationszone 21 gerade verlassen wird und der zweite Anschlag 73 gerade im Begriff ist, auf den vorgeordneten Rücksteller 72 aufzulaufen. Letzterer ist ebenfalls ortsfest angeordnet und befindet sich insbesondere am Steuerkurventräger 49, wobei er eine unveränderliche Position einnehmen kann.Figures 6 and 7 show the withdrawn position of a spindle unit 7 located in Abrück-turning position 64 Abrückungsteil 59. In Figure 7, a phase is shown in which the decoration zone 21 is just left and the second stop 73 is just about to the upstream reset 72 run up. The latter is also arranged stationary and is located in particular on the cam carrier 49, wherein it can assume a fixed position.

Die beiden Drehstellungen 64, 65 des Abrückungsteils 59 werden zweckmäßigerweise durch Federmittel 74 lösbar fixiert. Diese Federmittel 74 greifen einerseits mit radialem Abstand zur Drehachse 62 am Abrückungsteil 59 an (Angriffsstelle 75), und stützen sich andernends an einer Lagerstelle 76 am Grundkörper 9 ab. Dabei liegt die Angriffsstelle 75 in den beiden Drehstellungen 64, 65 auf entgegengesetzten Seiten einer die Lagerstelle 76 und die Drehachse 62 des Abrückungsteils 59 verbindenden gedachten Linie 77. Dies hat einen Schnappeffekt zur Folge, wobei das Abrückungsteil 59 in beiden Drehstellungen 64, 65 durch Federkraft gehalten wird, unter Überwindung der Federkraft jedoch drehbar ist, wobei die Federmittel 74 um die Lagerstelle 76 verschwenkt werden.The two rotational positions 64, 65 of the Abrückungsteils 59 are suitably fixed releasably by spring means 74. These spring means 74 engage on the one hand with a radial distance from the axis of rotation 62 at the Abrückungsteil 59 (point of attack 75), and are supported at the other end to a bearing 76 on the base body 9 from. In this case, the point of attack 75 is in the two rotational positions 64, 65 on opposite sides of a bearing 76 and the axis of rotation 62 of the Abrückungsteils 59th This has a snap effect result, wherein the Abrückungsteil 59 is held in both rotational positions 64, 65 by spring force, is overcoming the spring force, however, is rotatable, wherein the spring means 74 are pivoted about the bearing 76.

  15. Machine according to claim 14, characterised in that the withdrawal movement generated by the withdrawal means (56) is performed by the spindle units (7) in each case in its entirety.
  16. Machine according to claim 14 or 15, characterised in that the withdrawal movement of the mounting spindles (8) is generated by a radial displacement of the pivoting shaft (34).
  17. Machine according to claim 16, characterised in that the withdrawal means (56) for each spindle unit (7) contain on the spindle plate (3) a withdrawal section (59), mounted so as to be capable of rotating around an axis of rotation (62) parallel to the longitudinal axis (11) of the assigned mounting spindle (8), on which the assigned pivoting shaft (34) is eccentrically rotatably mounted with a parallel axis of rotation, wherein there are provided actuating means (63) which can generate a rotation of the withdrawal section (59) relative to the spindle plate (3) and to the assigned pivoting shaft (34) in order to position the withdrawal section (59) in two different rotary positions in which the pivoting shaft (34) is at a different distance from the axis of rotation (5) of the spindle plate (3).
  18. Machine according to claim 17, characterised in that the withdrawal section (59) is in the form of a hollow shaft and at least partially encompasses the pivoting shaft (34).
  19. Machine according to claim 17 or 18, characterised in that the withdrawal section (59) is fixed in the two rotary positions by spring means (74).
  20. Machine according to any of claims 17 to 19, characterised in that the actuating means (63) contain a tripping device (66), preferably sensor-controlled, switchable between an inoperative position and an operative position and which, in the operative position, extends into the movement path of a stop (67), connected non-rotatably to the withdrawal section (59) and arranged with radial clearance from its axis of rotation (62) so that, on hitting the stop, the rotary position of the withdrawal section (59) is changed for the purpose of displacing the assigned mounting spindle (8) into the withdrawn position.
  21. Machine according to any of claims 17 to 20, characterised in that the actuating means (63) contain a resetting device (72) which, in the withdrawn position of an mounting spindle (8), extends into the movement path of a stop (73), connected non-rotatably to the withdrawal section (59) and arranged with radial clearance from its axis of rotation (62) so that, on hitting the stop, the rotary position of the withdrawal section (59) is changed for the purpose of shifting the assigned mounting spindle (8) back into the original position.
