Description

Die Erfindung betrifft eine Transfervorrichtung für in einer Druckmaschine zu bedruckende oder bereits bedruckte Hohlkörper wie Hülsen, Tuben, Dosen oder dergleichen, gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a transfer device for printed or already printed in a printing machine hollow body such as sleeves, tubes, cans or the like, according to the preamble of patent claim 1.

Zum Bedrucken von über eine runde Außenkontur verfügenden Hohlkörpern wie Hülsen, Tuben, Dosen oder dergleichen sind Druckmaschinen vorgesehen, die einen rotationsangetriebenen Spindelteller aufweisen, der mit in Drehrichtung aufeinanderfolgend angeordneten Aufnahmespindeln versehen ist, an denen die Hohlkörper während des Bedruckvorganges gehalten werden. Dabei durchlaufen die Aufnahmespindeln bei der Rotation des Spindeltellers eine die Druckvorrichtung passierende Bahnkurve.For printing on a round outer contour possessing hollow bodies such as sleeves, tubes, cans or the like printing presses are provided which have a rotationally driven spindle plate, which is provided in the direction of rotation successively arranged receiving spindles on which the hollow body are held during the printing process. During the rotation of the spindle plate, the take-up spindles pass through a trajectory passing through the printing device.

Die zu bedruckenden Hohlkörper werden dem Spindelteller durch eine Zufuhr-Fördereinrichtung zugeführt, die in der Regel über eine endlos umlaufende Förderkette verfügt, an der Trägerstäbe angeordnet sind, auf denen die zuzuführenden Hohlkörper sitzen. In vergleichbarer Weise erfolgt regelmäßig die Abfuhr bereits bedruckter Hohlkörper durch eine Abfuhr-Fördereinrichtung. Dabei wird seitens der Fördereinrichtungen ein möglichst geringer Abstand der aufeinanderfolgenden Hohlkörper angestrebt, um eine möglichst geringe Baugröße bei möglichst hoher Fördergeschwindigkeit realisieren zu können. Würde der Abstand der Hohlkörper beispielsweise dem Teilungsmaß der Aufnahmespindeln des Spindeltellers entsprechen, hätte dies auch ein großes Bauvolumen zugeordneter Trockner zur Folge, durch die die Hohlkörper hindurchgeschleust werden. Ebenso erhöht sich bei derselben Taktzahl bei einer größeren Kettenteilung die Geschwindigkeit der Förderkette der Fördereinrichtung, was einen erhöhten Kettenverschleiß und eine größere Antriebsleistung zur Folge hat.The hollow bodies to be printed are fed to the spindle plate by a feed conveyor, which generally has an endlessly circulating conveyor chain on which support rods are arranged, on which the hollow bodies to be supplied are seated. In a comparable manner, the removal of already printed hollow body by a discharge conveyor takes place regularly. In this case, the smallest possible distance of the successive hollow body is sought on the part of the conveyors in order to realize the smallest possible size at the highest possible conveying speed can. Would the distance of the hollow body, for example, correspond to the pitch of the spindles of the spindle plate, this would also a large volume associated dryer result, through which the hollow body are passed. Likewise, at the same number of cycles with a larger chain pitch increases the speed of the conveyor chain of the conveyor, which has an increased chain wear and a greater drive power result.

Durch die somit vorhandene unterschiedliche Teilung der Aufnahmespindeln des Spindeltellers und der Trägerstäbe der Fördereinrichtungen ergibt sich ein Transferproblem beim Transferieren der Hohlkörper zwischen der jeweiligen Fördereinrichtung und dem Spindelteller. Dieses wird nach Kenntnis der Anmelderin bisher häufig durch mehrstufige Transfervorgänge zu beheben versucht, wobei die Hohlkörper zwischen den Fördereinrichtungen und dem Spindelteller mehrmals zwischen Transfertrommeln mit zunehmender Teilung und entsprechend unterschiedlichen Rotationsgeschwindigkeiten transferiert werden. Durch die große Anzahl der Übergabestellen ergibt sich jedoch ein hoher Platzbedarf. Auch sind die Übergabevorgänge aufgrund der unterschiedlichen Trommelgeschwindigkeiten noch immer störungsbehaftet und lassen insbesondere hohe Transportgeschwindigkeiten der Hohlkörper nicht zu.The thus existing different pitch of the take-up spindles of the spindle plate and the support rods of the conveyors results in a transfer problem when transferring the hollow body between the respective conveyor and the spindle plate. To the knowledge of the applicant, this has hitherto frequently been attempted to be remedied by multi-stage transfer processes, wherein the hollow bodies between the conveyors and the spindle plate are transferred several times between transfer drums with increasing pitch and correspondingly different rotational speeds. Due to the large number of transfer points, however, results in a large amount of space. Also, the transfer operations are still troublesome due to the different drum speeds and in particular do not allow high transport speeds of the hollow body.

Die WO 97/07979 beschreibt eine weitere Ausführungsform einer Transfervorrichtung, bei der eine neben dem Spindelteller angeordnete Transfertrommel zum Einsatz gelangt, die jedoch über die gleichen Abmessungen wie der Spindelteller verfügt, was insgesamt wiederum sehr hohe Abmessungen zur Folge hat.The WO 97/07979 describes a further embodiment of a transfer device, in which a arranged next to the spindle plate transfer drum is used, but which has the same dimensions as the spindle plate, which in turn has a very high overall dimensions result.

Aus der US 5 564 334 A ist eine Druckmaschine bekannt, die mit einer Transfervorrichtung der eingangs genannten Art ausgestattet ist, um bedruckte Hohlkörper von einem Spindelteller auf eine Förderkette zu transferieren. Die Transfervorrichtung besitzt einen scheibenförmigen Transferrotor mit als Saugvorrichtungen ausgebildeten Halteeinheiten für die Hohlkörper, wobei die Halteeinheiten an radialen Führungsschlitzen verstellbar geführt sind. Zur Steuerung der radialen Bewegung greifen die Halteeinheiten in an einem Stator ausgebildete Steuerkurven ein. Dadurch werden die Halteeinheiten bei der Rotation des Transferrotors auf einen Abstand zueinander gebracht, der dem Abstand der an der Förderkette angeordneten Tragstäbe entspricht.From the US 5 564 334 A a printing machine is known which is equipped with a transfer device of the type mentioned is to transfer printed hollow body of a spindle plate on a conveyor chain. The transfer device has a disc-shaped transfer rotor with suction units designed as holding units for the hollow body, wherein the holding units are guided adjustably on radial guide slots. To control the radial movement, the holding units engage in control cams formed on a stator. As a result, during the rotation of the transfer rotor, the holding units are brought to a distance which corresponds to the distance between the carrying bars arranged on the conveyor chain.

Es ist die Aufgabe der vorliegenden Erfindung, eine Transfervorrichtung zu schaffen, die auch im Hochgeschwindigkeitsbereich einen zuverlässigen Transfer von Hohlkörpern zwischen einerseits dem Spindelteller und andererseits einer zur Zufuhr der Hohlkörper dienenden Zufuhr-Fördereinrichtung und/oder einer zur Abfuhr der Hohlkörper dienenden Abfuhr-Fördereinrichtung ermöglicht.It is the object of the present invention to provide a transfer device which enables a reliable transfer of hollow bodies between the one hand the spindle plate and on the other hand serving for supplying the hollow body feed conveyor and / or serving for removal of the hollow body discharge conveyor even at high speed ,

Gelöst wird diese Aufgabe durch eine Transfervorrichtung mit den Merkmalen des Patentanspruches 1.This object is achieved by a transfer device having the features of patent claim 1.

Auf diese Weise kann auch bei hohen Fördergeschwindigkeiten und bei im Vergleich zur Teilung der am Spindelteller vorgesehenen Aufnahmespindeln sehr geringem Zufuhr- bzw. Abfuhrabstand der Hohlkörper ein sauberer, kontinuierlicher Hohlkörpertransfer zwischen einerseits dem Spindelteller und andererseits einer Zufuhr-Fördereinrichtung und/oder einer Abfuhr-Fördereinrichtung gewährleistet werden. Die mit der Transfervorrichtung ausgestattete Druckmaschine lässt sich daher auch im Hochgeschwindigkeitsbereich einsetzen. Der Transfer zwischen einer jeweiligen Fördereinrichtung und dem Spindelteller wird durch einen rotationsangetriebenen Transferrotor bewirkt, der mit Halteeinheiten bestückt ist, die jeweils einen Aufnahmeplatz für einen Hohlkörper definieren. Durch Variation des zwischen den Halteeinheiten und der Drehachse des Transferrotors gemessenen Abstandes können die von den Aufnahmeplätzen und von den Aufnahmespindeln durchlaufenen Bahnkurven derart beeinflusst werden, dass sie im Bereich einer zwischen dem Transferrotor und dem Spindelteller befindlichen Transferzone einen übereinstimmenden Bahnverlauf mit übereinstimmender Geschwindigkeit und Teilung aufweisen. Beim Durchlaufen dieser Strecke können die Hohlkörper störungsfrei zwischen den einander paarweise koaxial zugeordneten Aufnahmeplätzen und Aufnahmespindeln transferiert werden.In this way, even at high conveying speeds and compared to the division of the spindles provided on spindle spindles very low Zufuhr- or Abfuhrabstand the hollow body a clean, continuous transfer of hollow body between on the one hand the spindle plate and on the other hand, a feed conveyor and / or a discharge conveyor be guaranteed. The printing machine equipped with the transfer device can therefore also be used in the high-speed range. The transfer between a respective conveyor and the Spindle plate is caused by a rotation-driven transfer rotor, which is equipped with holding units, each defining a receiving space for a hollow body. By varying the distance measured between the holding units and the axis of rotation of the transfer rotor, the trajectories traversed by the receiving stations and the take-up spindles can be influenced in such a way that they have a matching trajectory with matching speed and pitch in the region of a transfer zone located between the transfer rotor and the spindle plate , When passing through this route, the hollow body can be transferred without interference between each pairwise coaxial associated receiving spaces and spindles.

Um in der Transferzone den gewünschten übereinstimmenden Bahnverlauf mit übereinstimmender Teilung zu realisieren, kann ausschließlich eine entsprechende Positionierung der Halteeinheiten des Transferrotors stattfinden. Allerdings ist zusätzlich auch eine Positionierung der Aufnahmespindeln möglich, wobei zweckmäßigerweise der größte Teil der Positionsanpassung durch die Halteeinheiten erfolgt, während seitens der Aufnahmespindeln eine nur geringe, auch als Bahnkorrektur bezeichenbare Positionierung stattfindet.In order to realize the desired coincident trajectory with matching pitch in the transfer zone, only a corresponding positioning of the holding units of the transfer rotor can take place. However, in addition, a positioning of the take-up spindles is possible, wherein expediently, the largest part of the position adjustment is performed by the holding units, while on the part of the take-up spindles takes place only a small, also marked as a path correction positioning.

Der unmittelbare Transfer zwischen dem Transferrotor und dem Spindelteller wird durch die Halteeinheiten bewirkt, die in einer zur Drehachse des Transferrotors parallelen Transferrichtung verstellbar gelagert sind und zur Durchführung eines Hohlkörper-Transfervorganges beim Durchlaufen der Transferzone zu einer Transferbewegung in der Transferrichtung veranlasst werden, wobei sie jeweils einen Hohlkörper zwischen zueinander koaxialen Paaren von Aufnahmeplätzen und Aufnahmespindeln transferieren. Je nach Transferrichtung werden die Hohlkörper dabei von den Halteeinheiten entweder auf die Aufnahmespindeln aufgesteckt oder von diesen abgezogen. Die Transferbewegung wird in Abhängigkeit von der momentanen Drehposition des Transferrotors ausgeführt, wozu mit einer Steuerkurve ausgestattete Steuermittel vorhanden sind.The direct transfer between the transfer rotor and the spindle plate is effected by the holding units, which are adjustably mounted in a direction parallel to the axis of rotation of the transfer rotor transfer direction and to carry out a hollow body transfer process when passing through the transfer zone to a transfer movement in the transfer direction are caused, wherein they each transfer a hollow body between mutually coaxial pairs of receiving spaces and take-up spindles. Depending on the direction of transfer, the Hollow body thereby attached by the holding units either on the receiving spindles or deducted from these. The transfer movement is carried out as a function of the instantaneous rotational position of the transfer rotor, for which control means equipped with a control cam are provided.

An dieser Stelle sei darauf hingewiesen, dass im Sinne der vorliegenden Erfindung unter den Begriffen "Drucken" und "Bedrucken" oder dergleichen jedwede Art der Dekoration von Hohlkörpern zu verstehen ist, wobei insbesondere an Farb- und/oder Lackauftrag, Etikettieren, Folienprägen und Siebdruck gedacht ist. Entsprechend ist unter dem Begriff "Druckmaschine" jedwede für eine Dekoration der vorerwähnten Art dienende und dementsprechend ausgestattete Maschine zu verstehen.It should be noted that for the purposes of the present invention, the terms "printing" and "printing" or the like any kind of decoration of hollow bodies is to be understood, in particular on paint and / or paint application, labeling, foil stamping and screen printing thought is. Accordingly, the term "printing press" is to be understood as meaning any machine which is used for a decoration of the aforementioned type and accordingly equipped.

Weitere vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further advantageous embodiments of the invention will become apparent from the dependent claims.

Die zueinander parallelen Drehachsen des Transferrotors und des Spindeltellers sind zweckmäßigerweise derart versetzt zueinander angeordnet, dass die Drehachse des Transferrotors außerhalb der in sich geschlossenen ersten Bahnkurve der Aufnahmespindeln liegt. Der Abstand beider Drehachsen zur Transferzone ist dabei zweckmäßigerweise identisch. Im Betrieb erfolgt zweckmäßigerweise eine Rotation des Transferrotors und des Spindeltellers mit entgegengesetztem Drehsinn, so dass sich in der Transferzone gleichgerichtete Bahnbewegungen der Aufnahmeplätze und der Aufnahmespindeln einstellen.The mutually parallel axes of rotation of the transfer rotor and the spindle plate are expediently arranged offset from one another such that the axis of rotation of the transfer rotor is outside the self-contained first trajectory of the take-up spindles. The distance between the two axes of rotation to the transfer zone is expediently identical. In operation, a rotation of the transfer rotor and the spindle plate expediently takes place in the opposite direction of rotation, so that rectified path movements of the receiving locations and the receiving spindles are established in the transfer zone.

Der Transferrotor ist vorzugsweise trommelartig ausgebildet, wobei sich die Halteeinheiten insbesondere im Bereich der radial nach außen orientierten Mantelfläche des Transferrotors befinden.The transfer rotor is preferably drum-shaped, wherein the holding units, in particular in the region of the radial are outwardly oriented lateral surface of the transfer rotor.

Zum Halten der Hohlkörper während des Transfervorganges zwischen einer Fördereinrichtung und dem Spindelteller, können die Halteeinheiten über geeignete Vakuumhaltemittel verfügen, die eine unterdruckbedingte Fixierung bewirken. Allerdings wären auch andere geeignete Haltemittel möglich.For holding the hollow body during the transfer process between a conveyor and the spindle plate, the holding units may have appropriate vacuum holding means, which cause a negative pressure-related fixation. However, other suitable holding means would be possible.

Die Übergabe der Hohlkörper zwischen einer jeweiligen Fördereinrichtung und dem Transferrotor kann in vergleichbarer Weise stattfinden, wobei sich eine Vereinfachung dadurch ergibt, dass keine Teilungsanpassung notwendig ist. Die Zufuhr-Fördereinrichtungen und/oder die Abfuhr-Fördereinrichtung können jeweils eine Förderkette mit aufeinanderfolgend angeordneten Trägerstäben für die Hohlkörper aufweisen, die in einer zwischen der betreffenden Fördereinrichtung und dem Transferrotor befindlichen Zufuhrzone bzw. Abfuhrzone eine mit dem dortigen Bahnkurvenverlauf der Aufnahmeplätze der Halteeinheiten übereinstimmende Zufuhrkurve bzw. Abfuhrkurve durchlaufen, wobei sich Trägerstäbe und Aufnahmeplätze paarweise etwa koaxial zugeordnet sind, was durch Abziehen bzw. Aufstecken eine Hohlkörperübergabe während des Durchlaufens der Zufuhrkurve bzw. Abfuhrkurve gestattet.The transfer of the hollow body between a respective conveyor and the transfer rotor can take place in a comparable manner, whereby a simplification results from the fact that no pitch adjustment is necessary. The feed conveyors and / or the discharge conveyor can each have a conveyor chain with successively arranged support bars for the hollow bodies, which in a supply zone located between the respective conveyor and the transfer rotor or discharge zone a matching with the local trajectory of the receiving locations of the holding units supply curve Run through or discharge curve, with carrier rods and receiving stations are assigned in pairs about coaxially, which allows by peeling or plugging a hollow body transfer during the passage of the feed curve or discharge curve.

Damit die Hohlkörper sehr exakt auf den Transferrotor übergeben werden, kann die Zufuhr-Fördereinrichtung im Bereich der Zufuhrzone ein drehbewegliches Zentrierrad mit zur Drehachse des Transferrotors paralleler Drehachse und mit in Umfangsrichtung verteilten, nach radial außen hin offenen Zentriertaschen aufweisen. Die Förderkette ist so angeordnet, dass sie in dem der Zufuhrkurve vorgelagerten Bereich einer durch den Teilkreis der Zentriertaschen vorgegebenen Einlaufkurve folgt, wobei im Betrieb zugeführte Hohlkörper aufeinanderfolgend in diese Zentriertaschen eingelegt werden. Die Anordnung ist dann ferner so getroffen, dass im Übergangsbereich zwischen der Einlaufkurve und der Zufuhrkurve paarweise Zentriertaschen des Zentrierrades und Aufnahmeplätze des Transferrotors zusammentreffen, so dass die Hohlkörper von den die Aufnahmeplätze definierenden Halteeinheiten übernommen werden können.So that the hollow bodies are transferred very precisely to the transfer rotor, the supply conveyor can have a rotatable centering wheel in the region of the feed zone with an axis of rotation parallel to the axis of rotation of the transfer rotor and with centering pockets which are distributed radially outwards and distributed in the circumferential direction. The conveyor chain is arranged so that it follows in the feed curve upstream region of a predetermined by the pitch circle of the centering entry curve, which are supplied in operation supplied hollow body successively in these centering pockets. The arrangement is then further made such that in the transition region between the inlet curve and the feed curve pairs centering pockets of Zentrierrades and receiving locations of the transfer rotor meet, so that the hollow body can be taken over by the holding stations defining holding units.

In der Zeichnung ist ein Ausschnitt einer Druckmaschine abgebildet, die mit einer Transfervorrichtung 1 ausgestattet ist, welche eine Zufuhr-Transfereinheit 2 und eine Abfuhr-Transfereinheit 2' enthält. Die Zufuhr-Transfereinheit 2 dient zum Transferieren von über eine Zufuhr-Fördereinrichtung 3 zugeführten, zu bedruckenden Hohlkörpern 4 zum Spindelteller 5 der Druckmaschine. Durch die Abfuhr-Transfereinheit 2' werden bereits bedruckte Hohlkörper 4' vom Spindelteller 5 zu einer Abfuhr-Fördereinrichtung 3' transferiert, die die bedruckten Hohlkörper 4' abtransportiert.Shown in the drawing is a detail of a printing press equipped with a transfer device 1 which includes a supply transfer unit 2 and a discharge transfer unit 2 '. The feed transfer unit 2 serves for transferring hollow bodies 4 to be printed via a feed conveyor 3 to the spindle plate 5 of the printing machine. By the discharge transfer unit 2 'are already printed hollow body 4' from the spindle plate 5 to a Transfer conveyor 3 'transfers, which removes the printed hollow body 4'.

Der Spindelteller 5 ist im Betrieb zu einer Rotationsbewegung um eine Drehachse 6 mit einer durch Pfeil angedeuteten Spindelteller-Drehrichtung 7 antreibbar. Er ist mit einer Mehrzahl in der Spindelteller-Drehrichtung 7 aufeinanderfolgend angeordneten Aufnahmespindeln 8 ausgestattet, die mit zur Drehachse 6 paralleler Spindelachse 11 vom teller- oder scheibenförmigen Grundkörper 12 des Spindeltellers 5 wegragen. Den Aufnahmespindeln 8 können Antriebsmittel 13 zugeordnet sein, die einen Rotationsantrieb mit der Spindelachse 11 als Drehachse ermöglichen.The spindle plate 5 is in operation for a rotational movement about an axis of rotation 6 with a direction indicated by arrow spindle plate rotation 7 drivable. It is equipped with a plurality in the spindle plate rotation direction 7 consecutively arranged receiving spindles 8, which protrude with the axis of rotation 6 parallel spindle axis 11 from the plate-shaped or disc-shaped base body 12 of the spindle plate 5. The receiving spindles 8 can be assigned drive means 13, which allow a rotational drive with the spindle axis 11 as a rotation axis.

Die Antriebsmittel für den Drehantrieb des Spindeltellers 5 sind in der Zeichnung nicht näher dargestellt.The drive means for the rotary drive of the spindle plate 5 are not shown in detail in the drawing.

Die Zufuhr- und Abfuhrtransfereinheiten 2, 2' sind in der Spindelteller-Drehrichtung 7 beabstandet im Umfangsbereich des Spindeltellers 5 platziert. Außerdem befindet sich im Umfangsbereich des Spindeltellers 5 noch die nur strichpunktiert angedeutete Druckvorrichtung 14, die in an sich bekannter Weise mit mehreren Farbwerken ausgestattet sein kann und die über einen sogenannten Druckzylinder verfügt, der einen Farbauftrag bezüglich der zu bedruckenden Hohlkörper 4 ausführen kann.The supply and discharge transfer units 2, 2 'are placed in the spindle plate rotation direction 7 at a distance in the peripheral region of the spindle plate 5. In addition, located in the peripheral region of the spindle plate 5 is still only indicated by dash-dotted lines printing device 14, which can be equipped in a conventional manner with multiple inking units and which has a so-called printing cylinder, which can perform an application of paint with respect to the hollow body to be printed.

Die Druckmaschine dient zum Bedrucken von Hülsen, Tuben, Dosen oder sonstigen rotationssymmetrischen Hohlkörpern mit runder Außenkontur. Zu bedruckende Hohlkörper 4 werden über eine Zufuhr-Fördereinrichtung 3 zugeführt, mittels eines Transferrotors 15 von der Zufuhr-Fördereinrichtung 3 nacheinander an den Spindelteller 5 übergeben und von diesem durch die Druckvorrichtung 14 hindurchgeschleust. Anschließend werden die bedruckten Hohlkörper 4' durch einen weiteren, zur Abfuhr-Transfereinheit 2' gehörenden Transferrotor 15' vom Spindelteller 5 zur Abfuhr-Fördereinrichtung 3' transferiert.The printing machine is used for printing sleeves, tubes, cans or other rotationally symmetrical hollow bodies with a round outer contour. To be printed hollow body 4 are fed via a feed conveyor 3, by means of a Transfer rotors 15 of the feed conveyor 3 successively passed to the spindle plate 5 and passed therethrough by the printing device 14. Subsequently, the printed hollow bodies 4 'are transferred from the spindle plate 5 to the discharge conveyor 3' by a further transfer rotor 15 'belonging to the discharge transfer unit 2'.

Während ihres Aufenthaltes am Spindelteller 5 sind die Hohlkörper 4, 4' einzeln koaxial auf die Aufnahmespindeln 8 aufgesteckt.During their stay on the spindle plate 5, the hollow body 4, 4 'individually coaxially attached to the take-up spindles 8.

Ein jeweiliger Transferrotor 15, 15' ist durch nicht näher dargestellte Antriebsmittel zu einer Rotationsbewegung um seine Drehachse 16 antreibbar. Die Transferrotor-Drehrichtung ist durch Pfeil 17 angedeutet.A respective transfer rotor 15, 15 'is drivable by means not shown in detail to a rotational movement about its axis of rotation 16. The transfer rotor direction of rotation is indicated by arrow 17.

Beim Ausführungsbeispiel haben beide Transfereinheiten 2, 2' einen erfindungsgemäßen Aufbau. Prinzipiell wäre es allerdings denkbar, nur eine Transfereinheit 2, 2' entsprechend auszubilden und bei der anderen Transfereinheit auf an sich bekannte, konventionelle Mittel zurückzugreifen.In the embodiment, both transfer units 2, 2 'have a construction according to the invention. In principle, however, it would be conceivable to design only one transfer unit 2, 2 'correspondingly and to resort to conventional means known per se in the case of the other transfer unit.

Ein jeweiliger Transferrotor 15, 15' ist mit in Transferrotor-Drehrichtung 17 aufeinanderfolgend angeordneten Halteeinheiten 18 ausgestattet, die jeweils einen Aufnahmeplatz 21 zur lösbaren Aufnahme bzw. Halterung eines zu transferierenden Hohlkörpers 4, 4' definieren. Die Halteeinheiten 18 sind im Bereich der Aufnahmeplätze 21 mit Haltemitteln zum zeitweiligen Halten von Hohlkörpern 4, 4' ausgestattet, vorzugsweise mit Vakuumhaltemitteln 22, die über eine gewünschte Zeitdauer ein durch Unterdruck bedingtes Festhalten der die Aufnahmeplätze 21 einnehmenden Hohlkörper 4, 4' gewährleisten.A respective transfer rotor 15, 15 'is equipped with holding units 18 arranged successively in transfer rotor rotation direction 17, each of which defines a receiving space 21 for releasably receiving or holding a hollow body 4, 4' to be transferred. The holding units 18 are in the field of recording slots 21 with holding means for temporarily holding hollow bodies 4, 4 'equipped, preferably with vacuum holding means 22, over a desired period of time, a conditional by vacuum holding the Recording seats 21 engaging hollow body 4, 4 'ensure.

Die Halteeinheiten 18 sind im Bereich der Aufnahmeplätze 21 taschenartig ausgebildet und nach radial außen hin offen, so dass Hohlkörper 4, 4' in einer zur Drehachse 16 quer verlaufenden Richtung eingesetzt bzw. eingelegt oder entfernt werden können.The holding units 18 are pocket-like in the area of the receiving places 21 and are open radially outward, so that hollow bodies 4, 4 'can be inserted or inserted or removed in a direction transverse to the axis of rotation 16.

Die Aufnahmeplätze 21 durchlaufen bei der Rotation des Transferrotors 15, 15' eine in Figuren 1 und 4 strichpunktiert angedeutete erste Bahnkurve 23. Diese ist in sich geschlossen. An den Aufnahmeplätzen fixierte Hohlkörper 4, 4' werden entlang einer Teillänge dieser Bahnkurve 23 entsprechend mitbewegt.The receiving stations 21 go through during the rotation of the transfer rotor 15, 15 'a in FIGS. 1 and 4 dash-dotted lines indicated first trajectory 23. This is closed in itself. At the receiving locations fixed hollow body 4, 4 'are moved along a portion of this trajectory 23 accordingly.

Die am Spindelteller 5 vorgesehenen Aufnahmespindeln 8 und somit die daran gehaltenen Hohlkörper 4, 4' werden bei der Rotation des Spindeltellers 5 entlang einer in Figuren 1 und 4 strichpunktiert angedeuteten zweiten Bahnkurve 24 bewegt.The spindle spindles 5 provided on the receiving spindles 8 and thus the hollow body 4, 4 'held thereon during rotation of the spindle plate 5 along a in FIGS. 1 and 4 dash-dotted lines indicated second trajectory 24 moves.

Die Teilung T1, also der in Spindelteller-Drehrichtung 7 gemessene Abstand der Spindelachsen 11 zweier aufeinanderfolgender Aufnahmespindeln 8, ist relativ groß und vor allem durch das für die Drehlagerungen der Aufnahmespindeln 8 benötigte Bauvolumen bestimmt. Um eine ausreichend große Anzahl von Aufnahmespindeln 8 am Spindelteller 4 vorsehen zu können, bedarf es daher außerdem auch der Einhaltung eines relativ großen Radialabstandes A1 zwischen der Drehachse 6 des Spindeltellers 5 und einer jeweiligen Spindelachse 11.The pitch T 1 , that is, the distance of the spindle axes 11 of two consecutive take-up spindles 8, measured in spindle-disk rotational direction 7, is relatively large and determined, above all, by the volume of construction required for the rotary bearings of the take-up spindles 8. To be able to provide a sufficiently large number of take-up spindles 8 on the spindle plate 4, therefore, it is also necessary to maintain a relatively large radial distance A 1 between the axis of rotation 6 of the spindle plate 5 and a respective spindle axis 11.

Im Bereich der Zufuhr- bzw. Abfuhr-Fördereinrichtungen 3, 3' liegen hingegen andere Randbedingungen vor. Um hohe Fördergeschwindigkeiten realisieren zu können und gleichzeitig das Bauvolumen der Druckmaschine und eventueller Peripherieeinrichtungen wie Trockner oder dergleichen möglichst gering halten zu können, werden die Hohlkörper 4, 4' mit möglichst geringer Teilung T2, also mit möglichst geringem Zentrumsabstand unmittelbar aufeinanderfolgender Hohlkörper 4, 4' zugeführt bzw. abgeführt. Die Teilung T2 wird dabei vom Abstand in Förderrichtung unmittelbar aufeinanderfolgender Trägerstäbe 25 bestimmt, die mit zueinander paralleler Ausrichtung derart an einer Förderkette 26, 26' der Zufuhr- bzw. Abfuhr-Fördereinrichtung 3, 3' angeordnet sind, dass sie jeweils rechtwinkelig bezüglich der durch Pfeile 27 angedeuteten Umlaufrichtung der jeweiligen Förderkette 26, 26' gleichgerichtet wegragen. Durch nicht näher dargestellte Antriebsmittel werden die jeweils in sich geschlossenen Förderketten 26, 26' zu einer endlosen Umlaufbewegung in der Umlaufrichtung 27 angetrieben.In the area of the supply or discharge conveyors 3, 3 ', however, are other boundary conditions. In order to be able to realize high conveying speeds and at the same time be able to keep the construction volume of the printing press and any peripheral devices such as dryers or the like as low as possible, the hollow bodies 4, 4 'with the smallest possible pitch T 2 , ie with the smallest possible center distance directly successive hollow body 4, 4th supplied or discharged. The pitch T 2 is determined by the distance in the conveying direction directly successive support rods 25, which are arranged with parallel alignment so on a conveyor chain 26, 26 'of the supply and discharge conveyor 3, 3', that they each perpendicular to the The directions of rotation of the respective conveyor chain 26, 26 'indicated by arrows 27 project in the same direction. By not shown drive means, the self-contained conveyor chains 26, 26 'are driven to an endless circulation movement in the direction of rotation 27.

Mit Hilfe der Zufuhr- und Abfuhr-Transfereinheiten 2, 2' wird der Teilungsunterschied T1 - T2 ausgeglichen, so dass ein kontinuierlicher Hohlkörpertransfer mit hohen Transfergeschwindigkeiten möglich ist. Dabei werden die Hohlkörper zwischen einer jeweiligen Zufuhr- bzw. Abfuhr-Fördereinrichtung 3, 3' und dem zugeordneten Transferrotor 15, 15' mit der Teilung T2 übergeben, die wie erwähnt auf den Abstand der durch die Fördereinrichtungen zugeführten bzw. abgeführten Hohlkörper 4, 4' abgestimmt ist. Die Teilung der Halteeinheiten 18 bzw. der durch diese definierten Aufnahmeplätze 21 entspricht somit beim Durchlaufen des der Zufuhr- bzw. Abfuhr-Fördereinrichtungen 3, 3' zugeordneten Übergabe-Bahnabschnittes 28 vorzugsweise der vorerwähnten Teilung T2 und ist somit wesentlich geringer als die Teilung T1 der Aufnahmespindeln 8 beim Passieren der Druckvorrichtung 14.With the help of the supply and discharge transfer units 2, 2 ', the division difference T 1 - T 2 is compensated so that a continuous transfer of hollow bodies with high transfer rates is possible. In this case, the hollow bodies are transferred between a respective supply or discharge conveyor 3, 3 'and the associated transfer rotor 15, 15' with the division T 2 , which, as mentioned, is based on the distance of the hollow bodies 4 fed or removed by the delivery devices. 4 'is tuned. The division of the holding units 18 or the receiving seats 21 defined by them thus corresponds to the passage of the supply or discharge conveyors 3, 3 'associated transfer path section 28 preferably the aforementioned division T 2 and thus is substantially less than the pitch T 1 of the take-up spindles 8 when passing the printing device fourteenth

Der Transfer von Hohlkörpern 4, 4' zwischen dem Transferrotor 15, 15' und dem Spindelteller 5 vollzieht sich in einer Transferzone 31, wobei in dieser Transferzone die Teilungen der Aufnahmespindeln 8 und der Aufnahmeplätze 21 ein identisches Maß aufweisen.The transfer of hollow bodies 4, 4 'between the transfer rotor 15, 15' and the spindle plate 5 takes place in a transfer zone 31, the pitches of the receiving spindles 8 and the receiving stations 21 having an identical dimension in this transfer zone.

Um diese Teilungsanpassung vornehmen zu können, ist der Verlauf der ersten und zweiten Bahnkurven 23, 24 variabel. So sind die Halteeinheiten 18 quer zur Drehachse des Transferrotors 16 stufenlos verstellbar, um den zwischen den Aufnahmeplätzen 21 und der Drehachse 16 des Transferrotors 15, 15' gemessenen Abstand A2 variieren zu können. Vergleichbares gilt für die Aufnahmespindeln 8, die quer zur Drehachse 6 des Spindeltellers 5 stufenlos verstellbar sind.In order to make this division adjustment, the course of the first and second trajectories 23, 24 is variable. Thus, the holding units 18 are transversely adjustable transversely to the axis of rotation of the transfer rotor 16 in order to be able to vary the distance A 2 measured between the receiving stations 21 and the axis of rotation 16 of the transfer rotor 15, 15 '. The same applies to the receiving spindles 8, which are continuously adjustable transversely to the axis of rotation 6 of the spindle plate 5.

Den Halteeinheiten 18 und den Aufnahmespindeln 8 sind Steuermittel 32 zugeordnet, durch die die rechtwinkelig zur zugeordneten Drehachse 16, 6 verstellbaren Halteeinheiten 18 und/oder Aufnahmespindeln 8 derart relativ zueinander positionierbar sind, dass die Aufnahmeplätze 21 und die Aufnahmespindeln 8 die Transferzone 31 paarweise mit koaxialer Zuordnung durchlaufen, wobei sie mit der gleichen Geschwindigkeit bewegt werden und in ihren Bahnverläufen übereinstimmen. Die übereinstimmenden Bahnverläufe sind in Figuren 1 und 4 bei 33 angedeutet.The holding units 18 and the receiving spindles 8 are assigned control means 32, by means of which the holding units 18 and / or take-up spindles 8, which are adjustable at right angles to the associated rotation axis 16, 6, can be positioned relative to each other such that the receiving spaces 21 and the take-up spindles 8 coaxially with the transfer zone 31 Passage assignment, where they are moved at the same speed and coincide in their trajectories. The matching trajectories are in FIGS. 1 and 4 indicated at 33.

Somit können die Hohlkörper 4, 4' während der übereinstimmenden Bahnverläufe 33 störungsfrei von den Aufnahmeplätzen 21 des Transferrotors 15 der Zufuhr-Transfereinheit 2 zu den Aufnahmespindeln 8 des Spindeltellers 5 transferiert werden, oder mit umgekehrter Transferrichtung von den Aufnahmespindeln 8 des Spindeltellers 5 zu den Aufnahmeplätzen 21 des Transferrotors 15' der Abfuhr-Transfereinheit 2' übergeben werden.Thus, the hollow body 4, 4 'during the matching tracks 33 are smoothly transferred from the receiving stations 21 of the transfer rotor 15 of the feed transfer unit 2 to the take-up spindles 8 of the spindle plate 5, or with reverse transfer direction of the take-up spindles 8 of the spindle plate 5 to the receiving stations 21 of the transfer rotor 15 'of the discharge transfer unit 2' are transferred.

Wie aus Figuren 1 und 4 hervorgeht, findet die radiale Hubbewegung der Halteeinheiten 18 vorzugsweise auf dem gesamten Bahnabschnitt der ersten Bahnkurve 23 außerhalb des Übergabe-Bahnabschnittes 28 statt. Bei den Aufnahmespindeln 8 hingegen findet die radiale Hubbewegung vorzugsweise nur während des Durchlaufens der übereinstimmenden Bahnabschnitte 33 oder kurz davor und/oder kurz danach statt. Dies hängt damit zusammen, dass die zur Anpassung der Bahnverläufe stattfindende Hubbewegung bei den Aufnahmespindeln 8 weniger ausgeprägt ist als bei den Halteeinheiten 18, deren Positionierstrecke maßgeblich für die Teilungsanpassung verantwortlich ist.How out FIGS. 1 and 4 As can be seen, the radial lifting movement of the holding units 18 preferably takes place on the entire path section of the first trajectory 23 outside of the transfer path section 28. In contrast, in the case of the take-up spindles 8, the radial lifting movement preferably takes place only during the passage of the coinciding track sections 33 or shortly before and / or shortly thereafter. This is due to the fact that the stroke movement taking place for the adaptation of the pathways is less pronounced in the case of the take-up spindles 8 than in the case of the holding units 18, whose positioning path is decisively responsible for the division adjustment.

Zur Reduzierung des maschinentechnischen Aufwandes wäre es prinzipiell erstrebenswert, die Anpassung der Bahnkurvenverläufe beim gemeinsamen Durchlaufen der Transferzone 31 allein durch eine gesteuerte Positionierung der Halteeinheiten 18 vorzunehmen und dabei die Teilung von der anfänglichen Teilung T2 auf die unverändert beibehaltene größere Teilung T1 der Aufnahmespindeln 8 anzupassen. Um jedoch einen stetigen, keine Wendepunkte aufweisenden Verlauf der ersten Bahnkurve 23 zu gewährleisten, erfolgt beim Ausführungsbeispiel beim Durchlaufen der Transferzone 31 auch eine geringfügige Abstandsverringerung zwischen den Aufnahmespindeln 8 und der Drehachse 6 des Spindeltellers 5.To reduce the mechanical complexity, it would be desirable in principle to make the adjustment of the trajectory curves when passing through the transfer zone 31 alone by a controlled positioning of the holding units 18 and the division of the initial pitch T 2 to the unchanged maintained larger pitch T 1 of the take-up spindles. 8 adapt. However, in order to ensure a steady course of the first trajectory 23, which does not have any turning points, a slight reduction in distance takes place in the embodiment when passing through the transfer zone 31 between the take-up spindles 8 and the rotation axis 6 of the spindle plate 5.

Der konstruktive Aufbau der beispielsgemäßen Anordnung sieht vor, dass die zueinander parallelen Drehachsen 6, 16 des Spindeltellers 5 und eines jeweiligen Transferrotors 15, 15' derart mit Abstand radial versetzt zueinander angeordnet sind, dass die Drehachse 16 des betreffenden Transferrotors 15, 15' außerhalb der in sich geschlossenen zweiten Bahnkurve 24 der Aufnahmespindeln 8 liegt. Der Spindelteller 5 und ein jeweiliger Transferrotor 15, 15' sind rechtwinkelig zu den Drehachsen so zueinander versetzt, dass sie sich lediglich im Bereich der Transferzone 31 ein Stück weit seitlich überlappen. Dabei sind die Drehachsen 6, 16 des Spindeltellers 5 und der Transferrotoren 15, 15' jeweils zweckmäßigerweise mit gleichem Abstand zur Transferzone 31 angeordnet.The structural design of the arrangement according to the invention provides that the mutually parallel axes of rotation 6, 16 of the spindle plate 5 and a respective transfer rotor 15, 15 'are radially offset from each other at a distance such that the axis of rotation 16 of the respective transfer rotor 15, 15' outside the closed second trajectory 24 of the take-up spindles 8 is located. The spindle plate 5 and a respective transfer rotor 15, 15 'are at right angles to the axes of rotation offset from each other so that they overlap only a little way laterally in the region of the transfer zone 31. The axes of rotation 6, 16 of the spindle plate 5 and the transfer rotors 15, 15 'are each expediently arranged at the same distance from the transfer zone 31.

Spindelteller 5 und Transferrotoren 15, 15' rotieren im Betrieb gegensinnig, so dass sich in der überlappenden Transferzone 31 gleichgerichtete Bahnbewegungen der Aufnahmeplätze 21 und der Aufnahmespindeln 8 einstellen.Spindle plate 5 and transfer rotors 15, 15 'rotate in opposite directions during operation, so that in the overlapping transfer zone 31 rectified path movements of the receiving stations 21 and the take-up spindles 8 are established.

Die Bahnsteuerung der Halteeinheiten 18 und/oder der Aufnahmespindeln 8 könnte prinzipiell berührungslos veranlaßt und gesteuert werden. Beim Ausführungsbeispiel wird jedoch auf mechanische Mittel zurückgegriffen. So enthalten die Steuermittel 32 zur drehwinkelabhängigen Radialpositionierung der Halteeinheiten 18, und somit zur Vorgabe der ersten Bahnkurve 23, eine in sich geschlossene ortsfeste Steuerkurve 34, die mit Steuerflächen versehen ist, an denen bei der Rotation des Transferrotors 15, 15' mit den Halteeinheiten 18 zusammenarbeitende Kurvenfolger 35 entlang laufen, um eine von der momentanen Drehposition des Transferrotors 15, 15' abhängige Positionierung hervorzurufen. Die Kurvenfolger 35 können über reibungsarme Wälzkörper verfügen.The path control of the holding units 18 and / or the receiving spindles 8 could in principle be initiated and controlled without contact. In the embodiment, however, resort to mechanical means. Thus, the control means 32 for rotational angle-dependent radial positioning of the holding units 18, and thus for specifying the first trajectory 23, a self-contained stationary control cam 34 which is provided with control surfaces on which at the rotation of the transfer rotor 15, 15 'with the holding units 18th cooperating Curve follower 35 along to cause a dependent on the current rotational position of the transfer rotor 15, 15 'positioning. The cam follower 35 may have low-friction rolling elements.

Eine vergleichbare Anordnung ist auch seitens der Aufnahmespindeln 8 möglich, wobei hier die entsprechende Steuerkurve 36 eine geringere Erstreckung aufweisen kann und nicht in sich geschlossen sein muss, da sie aufgrund der oben geschilderten Umstände im wesentlichen nur eine Beeinflussung der momentan die Transferzone 31 durchlaufenden Aufnahmespindeln 8 vorzunehmen hat. Alternativ könnten auch andere Steuermittel vorgesehen sein, um die wegmäßig geringe Abrückung der Aufnahmespindeln beim Durchlaufen der übereinstimmenden Bahnkurven 33 zu verursachen.A comparable arrangement is also possible on the part of the take-up spindles 8, in which case the corresponding control cam 36 may have a smaller extent and need not be self-contained, since due to the circumstances described above, it is essentially only an influence on the take-up spindles 8 currently passing through the transfer zone has to make. Alternatively, other control means could be provided to cause the wegmäßig small disengagement of the take-up spindles when passing through the matching trajectories 33.

Wie aus den Figuren 2, 3, 5 und 6 hervorgeht, besitzen die Transferrotoren 15, 15' zweckmäßigerweise einen trommelartigen Aufbau, wobei sich die Halteeinheiten 18 im Bereich der radial nach außen orientierten Mantelfläche des jeweiligen Transferrotors 15, 15' befinden. Dabei können die Halteeinheiten 18 wie abgebildet über radial bezüglich der Drehachse 16 des Transferrotors 15, 15' teleskopierbare Führungseinrichtungen 37 am Grundkörper 19 des betreffenden Transferrotors 15, 15' verstellbar gelagert sein. Bevorzugt verfügen die teleskopierbaren Führungseinrichtungen über schlittenartig verschiebbar aneinander geführte Bestandteile, wobei Gleitführungen oder Wälzführungen zum Einsatz gelangen können.Like from the Figures 2 . 3 . 5 and 6 shows, the transfer rotors 15, 15 'expediently have a drum-like structure, wherein the holding units 18 in the region of the radially outwardly oriented lateral surface of the respective transfer rotor 15, 15' are located. In this case, the holding units 18 as shown by means of radially with respect to the axis of rotation 16 of the transfer rotor 15, 15 'telescopic guide means 37 on the base body 19 of the respective transfer rotor 15, 15' be adjustably mounted. Preferably, the telescoping guide means on slide-like slidably guided together components, with sliding guides or rolling guides can be used.

Während einer Umdrehung des der Zufuhr-Transfereinheit 2 zugeordneten Transferrotors 15 werden die Aufnahmeplätze 21 ausgehend von der der Zufuhr-Fördereinrichtung 3 zugeordneten Zufuhrzone 38 bei sich vorzugsweise kontinuierlich vergrößerndem Querabstand zur Drehachse 16 in die Transferzone 31 bewegt. Im Anschluss daran verringert sich der Radialabstand wieder bis zu dem der Teilung T2 entsprechenden Minimalabstand bei neuerlichem Eintreffen in der Zufuhrzone 38. Ein entsprechendes Bewegungsverhalten ergibt sich im Zusammenhang mit dem Transferrotor 15' der Abfuhr-Transfereinheit 2', wobei lediglich anstelle der Zufuhrzone 38 eine Abfuhrzone 38' tritt, in der die bedruckten Hohlkörper 4' an die Abfuhr-Fördereinrichtung 3' ausgegeben werden.During one revolution of the transfer rotor 15 assigned to the feed transfer unit 2, the receiving stations 21 are moved into the transfer zone 31, starting from the feed zone 38 assigned to the feed conveyor 3, at a preferably continuously increasing transverse distance from the axis of rotation 16. Following this, the radial distance decreases again up to the minimum distance corresponding to the pitch T 2 on renewed arrival in the feed zone 38. A corresponding movement behavior results in connection with the transfer rotor 15 'of the discharge transfer unit 2', wherein instead of the feed zone 38 a discharge zone 38 'occurs, in which the printed hollow body 4' are discharged to the discharge conveyor 3 '.

Zumindest während eines Teils der beim Durchlaufen der ersten Bahnkurve 23 zurückgelegten Wegstrecke werden die Halteeinheiten 18 auch zu einer überlagerten Transferbewegung in einer durch Doppelpfeil angedeuteten Transferrichtung 42 veranlasst. Diese Transferrichtung 42 ist zur Drehachse 16 des zugeordneten Transferrotors 15, 15' parallel und somit auch gleichgerichtet mit der Spindelachse 11 der Aufnahmespindeln 8.At least during a part of the distance traveled when passing through the first trajectory 23, the holding units 18 are also caused to superpose a transfer movement in a transfer direction 42 indicated by a double arrow. This transfer direction 42 is parallel to the axis of rotation 16 of the associated transfer rotor 15, 15 'and thus also rectified with the spindle axis 11 of the take-up spindles 8.

Die Transferbewegung wird durch strichpunktiert angedeutete Steuermittel 43 derart gesteuert, dass bei der Zufuhr-Transfereinheit 2 die mit einem zu bedruckenden Hohlkörper 4 bestückten Aufnahmeplätze 21 beim Eintritt in die Transferzone 31 in koaxialer Verlängerung der Aufnahmespindeln 8 platziert sind. Ein daran fixierter Hohlkörper 4 liegt daher der jeweils zugeordneten Aufnahmespindel 8 axial gegenüber. Im weiteren Verlauf der Rotationsbewegung des Transferrotors 15 wird die betreffende Halteeinheiten 18 in Richtung zu der synchron mitlaufenden Aufnahmespindel 8 verlagert, wobei der mitbewegte Hohlkörper 4 auf die Aufnahmespindel 8 aufgesteckt wird. Am Ende der übereinstimmenden Bahnverläufe 33 kann somit die Halteverbindung zwischen den Halteeinheiten 18 und den zugeordneten Hohlkörpern gelöst werden, da diese nunmehr auf den Aufnahmespindeln 8 sitzen.The transfer movement is controlled by dashed line indicated control means 43 such that in the feed transfer unit 2 which are equipped with a hollow body 4 to be printed receiving slots 21 are placed on entry into the transfer zone 31 in coaxial extension of the take-up spindles 8. A thereto fixed hollow body 4 is therefore the respective associated receiving spindle 8 axially opposite. In the further course of the rotational movement of the transfer rotor 15th the respective holding units 18 is displaced in the direction of the synchronously co-rotating receiving spindle 8, wherein the co-moving hollow body 4 is attached to the receiving spindle 8. At the end of the matching tracks 33 thus the holding connection between the holding units 18 and the associated hollow bodies can be solved, since these now sit on the take-up spindles 8.

Ein Bewegungsablauf mit entgegengesetzter Transferrichtung findet beim Transferrotor 15' der Abfuhr-Transfereinheit 2' statt. Hier sind die Halteeinheiten 18 beim Eintreffen an der Transferzone 31 so platziert, dass ihre Aufnahmeplätze 21 mit dem an einer Aufnahmespindel 8 gehaltenen Hohlkörper 4' zusammenfallen. Es werden dann die Vakuum-Haltemittel 22 oder dergleichen aktiviert, um den bereits bedruckten Hohlkörper 4' an der Halteeinheit 18 zu fixieren, worauf diese beim weiteren Durchlaufen der Transferzone 31 in Transferrichtung 42 von der Aufnahmespindel 8 entfernt wird und dabei gleichzeitig den Hohlkörper 4 von dieser Aufnahmespindel 8 abzieht.A sequence of movements with opposite transfer direction takes place in the transfer rotor 15 'of the discharge transfer unit 2'. Here, the holding units 18 are placed on arrival at the transfer zone 31 so that their receiving places 21 coincide with the held on a receiving spindle 8 hollow body 4 '. The vacuum holding means 22 or the like are then activated in order to fix the already printed hollow body 4 'to the holding unit 18, whereupon it is removed from the receiving spindle 8 during the further passage through the transfer zone 31 in the transfer direction 42 and at the same time the hollow body 4 of FIG this recording spindle 8 subtracts.

Die die Transferbewegung hervorrufenden Steuermittel 43 können zumindest teilweise mit den die Teilungsanpassung durchführenden Steuermitteln 32 identisch sein.The transfer means 43 causing the transfer movement may be at least partially identical to the control means 32 performing the division adjustment.

Die für die radiale Hubbewegung der Halteeinheiten verantwortliche Steuerkurve und die für die Transferbewegung zuständige Steuerkurve können gemeinsam an ein und demselben Körper vorgesehen sein, beispielsweise am Stator 20 des Transferrotors 15, 15'.The control cam responsible for the radial lifting movement of the holding units and the control cam responsible for the transfer movement can be provided together on one and the same body, for example on the stator 20 of the transfer rotor 15, 15 '.

Um eine exakte Transferbewegung zu erhalten, sind die Halteeinheiten 18 beim Ausführungsbeispiel an geeigneten Führungsmitteln des Transferrotors 15, 15' schlittenartig verschiebbar geführt, wobei die Führungsmittel an den oben erwähnten Führungseinrichtungen 37 vorgesehen oder unmittelbar von diesen gebildet sein können.In order to obtain an exact transfer movement, the holding units 18 are in the embodiment on suitable guide means of the transfer rotor 15, 15 'slidably guided slidably, the guide means may be provided on the above-mentioned guide means 37 or formed directly from these.

Der im Betrieb rotierende trommelartige Transferrotor 15, 15' beinhaltet zweckmäßigerweise einen Grundkörper 19 mit zwei axial beidseits des feststehenden Stators 20 angeordneten Scheiben, die mittels einer den Stator 20 durchsetzenden Drehachse fest miteinander verbunden sind und stets nur gemeinsam rotieren können. An den dem Stator 20 axial zugewandten Innenflächen sind die erwähnten Scheiben mit radial verlaufenden Führungen versehen, an denen die Führungseinrichtungen 37 radial verschiebbar gelagert sind. Letztere können einen bügelartigen Aufbau haben, mit zwei seitlichen Führungsarmen und einem sich dazwischen erstreckenden Verbindungsabschnitt, wobei sie den Stator 20 klammerähnlich umgreifen. Der Verbindungsabschnitt dient zur schlittenartig verschiebbaren Lagerung der zugeordneten Halteeinheit 18 und befindet sich am radial orientierten Umfangsbereich des Stators 20. Die Führungsarme greifen seitlich an den beiden Stirnseiten des Stators 20 vorbei und stehen mit den innen an den Scheiben angeordneten Führungen radial beweglich in Führungseingriff.The rotating during operation drum-like transfer rotor 15, 15 'expediently includes a base body 19 with two axially on both sides of the fixed stator 20 arranged discs which are firmly connected to each other by means of a stator 20 passing through the axis of rotation and always rotate together. At the stator 20 axially facing inner surfaces of the aforementioned discs are provided with radially extending guides on which the guide means 37 are mounted radially displaceable. The latter may have a bow-like construction, with two lateral guide arms and a connecting portion extending therebetween, while embracing the stator 20 like a clip. The connecting portion is used for slide-like sliding support of the associated holding unit 18 and is located on the radially oriented peripheral portion of the stator 20. The guide arms engage laterally on the two end faces of the stator 20 and are radially movable with the inside arranged on the discs guides in guiding engagement.

An den beiden den Scheiben zugewandten axial orientierten Stirnflächen des Stators 20 ist jeweils eine Steuerkurve 34 angeordnet, wobei die beiden Steuerkurven 34 einen übereinstimmenden Verlauf haben. Jeder Führungsarm ist mit einem Kurvenfolger 35 ausgestattet, der mit der zugeordneten Steuerkurve 34 zusammenarbeitet. Auf diese Weise wird eine sehr sichere zweiseitige Betätigung und Führung einer jeweiligen Führungseinrichtung 37 erreicht. Wenn der Transferrotor 15, 15' rotiert, bewegen sich die Führungseinrichtungen 37 mit ihren Verbindungsabschnitten und den daran geführten Halteeinheiten 18 in Umfangsrichtung entlang dem Mantel des Stators 20, wobei ihr Radialabstand zur Drehachse 16 des Transferrotors 15, 15' in Abhängigkeit vom Verlauf der Steuerkurven 34 verändert wird.At the two disks facing axially oriented end faces of the stator 20, a control cam 34 is arranged in each case, wherein the two control cams 34 have a matching course. Every leadership arm is with one Curve follower 35 equipped, which cooperates with the associated control cam 34. In this way, a very secure two-sided operation and guidance of a respective guide device 37 is achieved. When the transfer rotor 15, 15 'rotates, the guide means 37 move with their connecting portions and the holding units 18 guided circumferentially along the mantle of the stator 20, wherein their radial distance from the axis of rotation 16 of the transfer rotor 15, 15' depending on the course of the cams 34 is changed.

Dieser Radialbewegung ist wie erwähnt die Transferbewegung in der Transferrichtung 42 überlagert. Hierzu können die Steuermittel 43 eine am Mantel des Stators 20 angeordnete, sich um den Stator herum erstreckende, in sich geschlossene Steuerkurve aufweisen, mit der eine jeweilige Halteeinheit 18 in Führungseingriff steht. Jede Halteeinheit 18 kann zu diesem Zweck mit einem geeigneten Kurvenfolger ausgestattet sein. Entlang des Umfanges des Stators 20 ändert die Steuerkurve ihren axialen Abstand zu den Stirnseiten des Stators 20, entsprechend der gewünschten axialen Verlagerung der Halteeinheiten 18.As mentioned, this radial movement is superimposed on the transfer movement in the transfer direction 42. For this purpose, the control means 43 may have a self-contained on the mantle of the stator 20, extending around the stator, self-contained control curve, with which a respective holding unit 18 is in guiding engagement. Each holding unit 18 may be equipped with a suitable cam follower for this purpose. Along the circumference of the stator 20, the control cam changes its axial distance to the end faces of the stator 20, corresponding to the desired axial displacement of the holding units 18th

Um die überlagerte Radialbewegung und Transferbewegung zu ermöglichen, ohne den für die Transferbewegung erforderlichen Führungseingriff zwischen den Halteeinheiten 18 und dem Stator 20 zu verlieren und zugleich einen einfachen Aufbau zu ermöglichen, hat die Steuerkurve der Steuermittel 43 bezüglich der Drehachse 16 des Transferrotors 15, 15' einen nicht konzentrischen Verlauf. Sie ist hierzu zweckmäßigerweise an der Mantelfläche des Stators 20 vorgesehen, der eine Umfangskontur hat, deren Verlauf demjenigen der stirnseitigen Steuerkurven 34 entspricht. Es ändert sich also der Radialabstand der für die Transferbewegung verantwortlichen Steuerkurve der Steuermittel 43 von der Drehachse 16 entsprechend dem Verlauf der für die Radialbewegung verantwortlichen Steuerkurven 34. Es ist auf diese Weise gewährleistet, dass der Führungseingriff nie verloren geht. Der nicht-konzentrische und vorzugsweise unkreisförmige Umfangsverlauf des Stators 20 ist beispielsweise aus Fig. 3 und 6 ersichtlich.In order to enable the superimposed radial movement and transfer movement, without losing the required for the transfer movement guide engagement between the holding units 18 and the stator 20 and at the same time to allow a simple structure, the control cam 43 has the control means 43 with respect to the axis of rotation 16 of the transfer rotor 15, 15 ' a non-concentric course. It is expediently provided on the lateral surface of the stator 20, which has a peripheral contour has, whose course corresponds to that of the front-side cams 34. It thus changes the radial distance of the responsible for the transfer movement control cam of the control means 43 of the rotation axis 16 corresponding to the course of the responsible for the radial movement cams 34. It is ensured in this way that the leadership intervention is never lost. The non-concentric and preferably non-circular circumferential course of the stator 20 is for example made Fig. 3 and 6 seen.

Bedingt durch die besondere Ausgestaltung der Führungseinrichtungen 37 ergibt sich eine sehr präzise Führung für die schlittenartig ausgebildeten Halteeinheiten 18, die sich unabhängig von ihrer Position stets im Bereich der radial nach außen orientierten Mantelfläche des trommelförmigen Transferrotors 15, 15' befinden. Es ist auf diese Weise ein sehr exakter Transfer eines jeweiligen Hohlkörpers 4 zwischen einer Halteeinheit 18 und einer Aufnahmespindel 8 möglich.Due to the special design of the guide means 37 results in a very precise guide for the carriage-like holding units 18, which are always independent of their position in the radially outwardly oriented surface area of the drum-shaped transfer rotor 15, 15 '. It is possible in this way a very precise transfer of a respective hollow body 4 between a holding unit 18 and a take-up spindle 8.

Die Übergabe der Hohlkörper 4, 4' zwischen den Trägerstäben 25 einer jeweiligen Zufuhr- bzw. Abfuhr-Fördereinrichtung 3, 3' und dem jeweils zugeordneten Transferrotor 15, 15' erfolgt vergleichbar der Übergabe zwischen dem Transferrotor 15, 15' und dem Spindelteller 8. Auch hier werden die Halteeinheiten 18 in der Transferrichtung 42 verlagert, um die Hohlkörper 4, 4' entweder von den Trägerstäben 25 abzuziehen oder auf diese aufzustecken. Dieser Übergabevorgang spielt sich in der Zufuhrzone 38 bzw. Abfuhrzone 38' ab, und zwar beim Durchlaufen des beispielsweise einen Kreisbogen beschreibenden bogenförmigen Übergabe-Bahnabschnittes 28.The transfer of the hollow body 4, 4 'between the support rods 25 of a respective supply and discharge conveyor 3, 3' and the respectively associated transfer rotor 15, 15 'is comparable to the transfer between the transfer rotor 15, 15' and the spindle plate. 8 Again, the holding units 18 are displaced in the transfer direction 42 to either remove the hollow body 4, 4 'from the support bars 25 or aufzustecken on this. This transfer process takes place in the supply zone 38 or removal zone 38 ', namely when passing through the example of a circular arc descriptive arcuate transfer path section 28th

Die Zufuhr- bzw. Abfuhr-Fördereinrichtung 3, 3' befindet sich zweckmäßigerweise in einem dem Spindelteller 5 entgegengesetzten Umfangsbereich des zugeordneten Transferrotors 15, 15'. Dort sind, in Umfangsrichtung des Transferrotors 15, 15' beabstandet, zwei Umlenkräder 44, 45 mit zur Drehachse 16 des Transferrotors 15, 15' paralleler Drehachse platziert. Eine Stelle ihres Außenumfanges liegt jeweils auf dem Übergabe-Bahnabschnitt 28, wobei sie so von der Förderkette 26, 26' oder einem anderen vergleichbaren Förderstrang partiell umschlungen sind, dass sich ein Förderstrangabschnitt 46 einstellt, der mit dem Übergabe-Bahnabschnitt 28 der ersten Bahnkurve 23 zusammenfällt. Auf diese Weise werden die Trägerstäbe 25 gezwungen, bei der Umlaufbewegung der Förderkette 26, 26' eine mit dem Übergabe-Bahnabschnitt 28 übereinstimmende Zufuhrkurve bzw. Abfuhrkurve 47, 47' zu durchlaufen. Während dieses Durchlaufes sind sich die Trägerstäbe 25 und die Aufnahmeplätze 21 der Halteeinheiten 18 paarweise etwa koaxial zugeordnet, so dass durch die überlagerte Transferbewegung der Halteeinheiten 18 ein Abziehen der zu bedruckenden Hohlkörper 4 bzw. ein Aufstecken der bereits bedruckten Hohlkörper 4' von den bzw. auf die Trägerstäbe 25 stattfinden kann.The feed or removal conveyor 3, 3 'is expediently located in a circumferential region of the associated transfer rotor 15, 15' which is opposite the spindle plate 5. There are, in the circumferential direction of the transfer rotor 15, 15 'spaced, two deflecting wheels 44, 45 with the axis of rotation 16 of the transfer rotor 15, 15' parallel axis of rotation. A location of its outer periphery is in each case on the transfer path section 28, whereby they are so partially wrapped by the conveyor chain 26, 26 'or another comparable conveyor line, that sets a conveyor strand section 46, which is connected to the transfer path section 28 of the first trajectory 23rd coincides. In this way, the support rods 25 are forced to go through during the circulating movement of the conveyor chain 26, 26 'a matching with the transfer path section 28 supply curve or discharge curve 47, 47'. During this passage, the support rods 25 and the receiving stations 21 of the holding units 18 are paired approximately coaxially, so that by the superimposed transfer movement of the holding units 18 a removal of the printed hollow body 4 and a plugging the already printed hollow body 4 'of the or can take place on the support rods 25.

Die beiden Umlenkräder 44, 45 sind somit der jeweiligen Zufuhrkurve 47 bzw. Abfuhrkurve 47' in der Drehrichtung des Transferrotors 15, 15' vor- und nachgeordnet.The two deflection wheels 44, 45 are thus the respective supply curve 47 and discharge curve 47 'in the direction of rotation of the transfer rotor 15, 15' upstream and downstream.

Bevorzugt ist das der Zufuhrkurve 47 vorgeordnete Umlenkrad 44 der Zufuhr-Fördereinrichtung 3 als Zentrierrad 48 ausgebildet, das am Außenumfang mit in Umfangsrichtung verteilten und jeweils nach radial außen hin offenen Zentriertaschen 49 versehen ist. Deren Teilung entspricht der Teilung T2 der zugeführten Hohlkörper 4 und der damit übereinstimmenden Teilung T2 der Aufnahmeplätze 21 innerhalb des Übergabe-Bahnabschnittes 28. Mit anderen Worten durchläuft die Förderkette 26 in dem der Zufuhrkurve 47 vorgelagerten Bereich eine bezüglich dieser entgegengesetzt gekrümmte Einlaufkurve 52, die durch den Teilkreis der Zentriertaschen 49 vorgegeben ist.Preferably, the feed cam 47 upstream deflection wheel 44 of the feed conveyor 3 is formed as a centering 48, which is distributed on the outer circumference with circumferentially distributed and each radially outwardly open centering pockets 49th is provided. Their pitch corresponds to the pitch T 2 of the supplied hollow body 4 and the corresponding pitch T 2 of the receiving stations 21 within the transfer path section 28. In other words, the conveyor chain 26 passes in the area upstream of the supply curve 47 with respect to this oppositely curved inlet curve 52, which is predetermined by the pitch circle of the centering pockets 49.

Die Drehpositionen des Zentrierrades 48 und des Transferrotors 15 sind derart aufeinander abgestimmt, dass in dem Übergangsbereich 53 zwischen der Einlaufkurve 52 und der Zufuhrkurve 47 paarweise Zentriertaschen 49 und Aufnahmeplätze 21 zusammentreffen, zwischen denen dann eine Hohlkörperübergabe stattfinden kann.The rotational positions of the centering wheel 48 and the transfer rotor 15 are matched to one another such that in the transition region 53 between the inlet curve 52 and the supply curve 47 pairs of centering pockets 49 and receiving slots 21 meet, between which then a hollow body transfer can take place.

Durch das Zentrierrad 48 wird eine exakt zentrierte Übergabe zu bedruckender Hohlkörper 4 an den Transferrotor 15 gewährleistet.By centering 48 an exactly centered transfer to be printed hollow body 4 is ensured to the transfer rotor 15.

Abschließend sei nochmals darauf hingewiesen, dass die in der Beschreibung der Erfindung verwendeten Begriffe wie "Drucken" oder "Bedrucken" als Bezugnahmen nicht nur auf das eigentliche Bedrucken von Hohlkörpern, sondern auch im Sinne sonstiger Dekorationen oder Materialaufträge zu verstehen sind, beispielsweise Lackieren, Etikettieren, Folienprägen oder Siebdruck. Dementsprechend sind Bezugnahmen auf eine Druckmaschine bzw. eine Druckvorrichtung als Bezugnahmen auch auf zur Durchführung der vorgenannten Dekorierungen geeignete Maschinen und Vorrichtungen zu verstehen, beispielsweise Lackier- oder Etikettiermaschinen.Finally, it should be pointed out once again that the terms used in the description of the invention, such as "printing" or "printing", are to be understood not only as meaning the actual printing of hollow bodies but also in terms of other decorations or material orders, for example painting, labeling , Foil stamping or screen printing. Accordingly, references to a printing machine or a printing device are to be understood as references to suitable for performing the aforementioned decorations machines and devices, such as painting or labeling.
