Description

Die Erfindung bezieht sich auf ein kontinuierliches Verfahren, bei dem die Gebinde mit einer überlagerten Eigenrotation auf einer Transportbahn und die Dekors auf einer Trägerbahn mit konstanten Geschwindigkeiten und tangierend an einem Übertragungsort vorbeibewegt werden, wo die Dekors nacheinander unter Druck und Wärme auf die Gebinde übertragen werden.The invention relates to a continuous process, in which the container with a superimposed self-rotation on a transport track and the decorations on a carrier web with constant speeds and be moved tangentially past a transmission location, where the decorations are applied to the Containers are transferred.

Die Erfindung bezieht sich weiterhin auf eine entsprechende Vorrichtung, die aus einer antreibbaren endlosen Transportbahn mit gleichmäßig beabstandeten, antreibbaren und rotierenden Aufnahmemittel für die Gebinde, aus einer antreibbaren endlosen Trägerbahn mit gleichmäßig beabstandeten Dekors und aus einem als Übertragungsort ausgebildeten Kontaktbereich zwischen der Transportbahn und der Trägerbahn besteht, wobei im Bereich des Übertragungsortes Mittel zur Ausübung eines Drucks und Mittel zur Erwärmung des Dekors angeordnet sind.The invention further relates to a corresponding one Device consisting of a drivable endless Transport track with evenly spaced, drivable and rotating receptacles for the containers a drivable endless carrier track with even spaced decor and from a place of transmission trained contact area between the transport track and the carrier web, being in the area of the transfer location Means to exert pressure and means are arranged to heat the decor.

Derartige Verfahren und Vorrichtungen werden u.a. in der Lebensmittel- und Getränkeindustrie zum Dekorieren von Gebinden aus Papier, Kunststoff, Glas oder Metall angewendet. Such methods and devices are used inter alia. in the Food and beverage industry for decorating Containers made of paper, plastic, glass or metal are used.

Zur Dekoration von Gebinden in der eingangs genannten Art setzt sich aus den verschiedensten Gründen das Thermotransferverfahren verstärkt gegenüber anderen, z.B. dem Etikettierungsverfahren durch.For decorating containers in the aforementioned Art uses the thermal transfer process for a variety of reasons reinforced against others, e.g. the labeling process.

Dabei wird das Dekorationsmotiv mittels bekannter Drucktechnik in der Art auf eine Trägerbahn gedruckt, daß es durch ein Haftmittel geringerer Haftkraft mit der Trägerbahn verbunden und mit einem anderen Haftmittel mit höherer Haftkraft überzogen ist. Eine so hergestellte Trägerbahn wird mit den zu dekorierenden Gebinden in Kontakt gebracht. Durch Druck und Wärme in diesem Kontaktbereich löst sich das Dekor von der Trägerbahn und verbindet sich gleichzeitig mit dem Gebinde. Die Wärmezufuhr erfolgt dabei über das Gebinde.The decorative motif is created using known printing technology printed on a carrier web in such a way that it by means of an adhesive of lower adhesive strength with the carrier web connected and with another adhesive higher adhesive force is coated. A so made Carrier web is in with the containers to be decorated Brought in contact. By pressure and heat in this contact area the decor separates from the carrier web and connects to the container at the same time. The heat supply takes place via the container.

Dieses Verfahren ist demnach nur bei Gebinden mit hoher Wärmekapazität z.B. Glasflaschen einsetzbar.This method is therefore only for containers with high Heat capacity e.g. Glass bottles can be used.

Ein kontinuierliches Verfahren und eine Vorrichtung dazu, bei dem das Thermotransferverfahren auch bei Gebinden mit geringer Wärmekapazität z.B. Kunststoffgebinden einsetzbar ist, sind in der DE 44 37 379.1 beschrieben. Hierbei wird die Trägerbahn in jeweils ein Druckmotiv tragende Einzelabschnitte getrennt und auf beheizte Auftragssegmente überführt, die mit gleichen Abständen auf einem Auftragsfördermittel angeordnet sind. Dieses Auftragsfördermittel übernimmt kurzzeitig die Gebinde in der Art, daß jedem Auftragssegment ein Gebinde zugeordnet ist. Während des Transportes wird dann das Dekor vom Einzelabschnitt auf das Gebinde übertragen. Dieses Verfahren erfordert aber wegen einer Vielzahl von Einzeloperationen einen hohen gerätetechnischen Aufwand. Weiterhin gibt es Probleme bei der Koordinierung der vielen Einzelbewegungen von den Schneckenförderern für die Gebinde, vom Auftragsfördermittel für die Gebinde und die Auftragssegmente, von den Auftragssegmenten, von den Gebinden, vom Endlosförderer für die Dekors und vom Schneidaggregat. Diese Koordination der Einzelbewegungen ist nur durch eine aufwendige Getriebe- und Kurvensteuerung möglich oder kann nur durch entsprechende elektrische Getriebe realisiert werden.A continuous process and an apparatus therefor in which the thermal transfer process also applies to containers with low heat capacity e.g. Plastic containers can be used are described in DE 44 37 379.1. Here, the carrier web is printed in a print motif load-bearing individual sections separated and on heated order segments transferred on at equal intervals an order funding are arranged. This order funding temporarily takes over the containers in the way that a container is assigned to each order segment is. During the transport, the decor is then removed from the Transfer the individual section to the container. This method but required because of a large number of individual operations a high expenditure on equipment. There are also problems with the coordination of the many individual movements from the screw conveyors for the containers, from the order funding for the containers and the order segments, from the order segments, from the containers, from the endless conveyor for the decorations and from Cutting unit. This coordination of the individual movements is only through complex gear and curve control possible or can only by appropriate electrical Gears can be realized.

Außerdem stellt die Handhabung der einzelnen Etikettenabschnitte eine Leistungsbegrenzung der Maschine dar. Besonders nachteilig ist, daß ein maschinengeschwindigkeitsabhängiger Wärmeenergieeintrag in das Etikettenmaterial nicht möglich ist. Dadurch wird der variable Leistungsbereich der Maschine stark eingeschränkt, welches sich nachteilig in einer Gesamtproduktionslinie auswirkt. Bei niedriger Geschwindigkeit besteht außerdem die Gefahr einer thermischen Beschädigung vom Etikettenmaterial und dünnwandigen Kunststoffgebinden.In addition, the handling of the individual label sections is a limitation of the machine's performance. It is particularly disadvantageous that a machine speed-dependent Entry of thermal energy into the label material not possible. This makes the variable performance range the machine is severely restricted, which adversely affects an overall production line. At low speed there is also the risk of thermal damage to the label material and thin-walled plastic containers.

Mit der US-A-4,806,197 wurde nun eine Thermotransfereinrichtung für gewölbte Gebinde bekannt, bei der die Gebinde auf einer Transportbahn und die Dekors auf einer Trägerbahn tangierend an einem Übertragungsort vorbeibewegt werden. Dabei werden die Dekors nacheinander unter Druck und Wärme auf die Gebinde übertragen.With the US-A-4,806,197 has now become a thermal transfer device known for domed containers, where the containers on a transport track and the decorations on one Carrier web tangentially moved past a transfer location become. The decors are placed one after the other Transfer pressure and heat to the container.

Von großem Nachteil ist, daß die Bewegungen der Transportbahn und der Trägerbahn in gleicher Richtung ablaufen. Das verlangt eine gleiche Teilung der Gebinde auf der Transportbahn und der Dekors auf der Trägerbahn, was nur mit einem erhöhten technischen Aufwand zu erreichen ist. Außerdem ergibt sich dadurch eine hohe Übertragungszeit. A major disadvantage is that the movements of the transport path and run the carrier web in the same direction. This calls for an equal division of the containers the transport track and the decorations on the carrier track what can only be achieved with increased technical effort is. This also results in a long transmission time.

Die nach dem Thermotransferverfahren bedruckten Gebinde bedürfen in der Regel noch einer Wärmenachbehandlung, damit das übertragende Farbbild einen erhöhten Glanz erhält, die Farben getrocknet und die Haftung des Untergrundes verbessert wird.The containers printed using the thermal transfer process usually require additional heat treatment, so that the transferred color image gets an increased gloss, the paints dried and the adhesion of the surface is improved.

Dazu wird in der DE 44 27 870.5 beschrieben, die frisch bedruckten Gebilde mit dem noch feuchten Druckbild über ein gesondertes Abfördermittel in einen gesonderten Ofen zu transportieren.For this purpose, DE 44 27 870.5 describes that fresh printed structures with the still damp print image above a separate discharge in a separate oven to transport.

Zum allgemeinen Stand der Technik gehört es auch, an Stelle des Ofens eine offene Flamme in Verbindung mit einer Rotation der Gebinde einzusetzen. Eine offene Flamme stellt aber sehr hohe Anforderungen an die Gerätetechnik und läßt obendrein den Einsatz bei Gebinden aus Kunststoff wegen der Gefahr von Deformationen nicht zu.It also belongs to the general state of the art Place an open flame in connection with the stove rotation of the containers. An open one Flame, however, places very high demands on the device technology and on top of that leaves the use with containers not made of plastic because of the risk of deformation to.

Es besteht daher die Aufgabe, ein Verfahren und eine Vorrichtung der vorliegenden Gattung zu schaffen, die mit großem variablen Leistungsbereich und einfacher Technik arbeitet.There is therefore the task of a procedure and a To create device of the present genus, the with large variable power range and easier Technology works.

Diese Aufgabe wird gelöst mit einem Verfahren mit den Merkmalen des Anspruchs 1.This problem is solved with a method with the Features of claim 1.

Der besondere Vorteil der Erfindung liegt in der äußerst hohen Umfangsgeschwindigkeit der Gebinde.The particular advantage of the invention lies in the extreme high peripheral speed of the containers.

Diese hohe Umfangsgeschwindigkeit ermöglicht einen kontinuierlichen Ablauf, da die Abstände der Gebinde auf der Transportbahn und die Abstände der Dekors auf der Trägerbahn nunmehr unabhängig voneinender sind. Ein Zuschneiden in Einzelabschnitte der Trägerbahn ist nicht mehr notwendig.This high peripheral speed enables a continuous Expiry because the distances of the containers on the transport path and the spacing of the decorations on the Carrier web are now independent of one another. A cropping in individual sections of the carrier web is not more necessary.

Die minimale Berührungszeit verhindert obendrein einen Temperaturtransfer aus der Trägerbahn in das Gebinde, was insbesondere bei Kunststoffgebinden von Vorteil ist. Außerdem bleiben die beiden temperaturabhängigen Schichten von Haftmittel auf der Trägerbahn unbeeinflußt.The minimal touch time also prevents you Temperature transfer from the carrier web to the container, which is particularly advantageous for plastic containers. In addition, the two temperature-dependent layers remain unaffected by adhesive on the carrier web.

Es ist besonders zweckmäßig, wenn die Gebinde nicht separat, sondern von der Bewegung der Trägerbahn angetrieben werden. Dadurch entfällt eine sonst notwendige Koordination der Bewegungen von Gebinde und Trägerbahn. Vorteilhaft ist es, wenn neben dem zu dekorierenden Gebinde gleichzeitig auch das in Bewegungsrichtung dahinterliegende Gebinde von der Trägerbahn angetrieben wird. Damit ermöglicht man dem dahinterliegenden Gebinde eine Beschleunigungsphase und vermeidet damit eine Geschwindigkeitsdifferenz zwische Gebinde und Trägerbahn während des Transfers.It is particularly useful if the containers are not separate, but driven by the movement of the carrier web become. This eliminates the otherwise necessary coordination the movements of the container and carrier web. It is advantageous if next to the container to be decorated at the same time that behind it in the direction of movement Container is driven by the carrier web. This enables the container behind Acceleration phase and thus avoids a speed difference between container and carrier web during of the transfer.

Es ist weiterhin von Vorteil, wenn die notwendige Wärme vor dem oder am Übertragungsort zugeführt wird. Dabei läßt sich in unmittelbarer Nähe des Übertragungsortes die Wärmezufuhr am besten dosieren und der Verlust an Wärme ist genauer kalkulierbar.It is also beneficial if the necessary heat is supplied before or at the transfer location. there can be in the immediate vicinity of the transmission location it is best to dose the heat supply and the loss Heat can be calculated more precisely.

Besonders günstig ist es, wenn die Erwärmzeit sich nach der Geschwindigkeit der Trägerbahn richtet und wenn diese Regelung automatisch erfolgt.It is particularly favorable when the warming up time is over the speed of the carrier web is directed and if this Regulation takes place automatically.

Das wirkt sich wieder positiv auf den Wärmeverlauf und damit auf die Qualität des Dekortransfers aus. This has a positive effect on the heat flow and the quality of the decor transfer.

Von einem besonderen Vorteil ist es, wenn die Gebinde mit den frischen Dekors eine Wärmenachbehandlungseinrichtung passieren, um einen höheren Farbenglanz zu erhalten. Dabei ist es günstig die vorhandene Transportbahn auszunutzen und die Gebinde an einer stationären und temperaturgeregelten Wärmequelle vorbeizuführen.It is of particular advantage if the containers with the fresh decorations a heat treatment device happen to get a higher color gloss. It is cheap the existing transport track exploit and the containers on a stationary and temperature-controlled heat source.

Die Aufgabe der Erfindung wird gelöst mit einer Vorrichtung mit den Merkmalen des Anspruchs 8.The object of the invention is achieved with a device with the features of claim 8.

Es ist günstig, die Aufnahmemittel für die Gebinde freidrehend auszuführen und das zu dekorierende oder das zu dekorierenden und das nachfolgende Gebinde durch die Trägerbahn anzutreiben.It is favorable to freely rotate the receptacles for the containers to execute and to decorate or to decorating and the subsequent packaging by the To drive the carrier web.

Es ist aber auch möglich. einen gesonderten herkömmlichen Antrieb zu verwenden. Dabei sind Mittel zur Realisierung gleicher Umfangsgeschwindigkeiten einzusetzen. Möglich ist auch die Kombination beider Antriebsmöglichkeiten. So wird über den gesonderten Antrieb eine Geschwindigkeit am Gebinde kleiner als die erforderliche Geschwindigkeit erzeugt und die fehlende Differenzgeschwindigkeit durch die Trägerbahn realisiert. Dazu ist der gesonderte Antrieb mit einem zusätzlichen Freilauf auszurüsten. But it is also possible. a separate conventional Drive to use. Thereby are means of realization use the same peripheral speeds. It is also possible to combine both drive options. In this way, a speed is achieved via the separate drive on the container smaller than the required Speed generated and the missing differential speed realized by the carrier web. Is to the separate drive with an additional freewheel equip.

In einer zweckmäßigen Ausgestaltung ist dem Führungselement für die Trägerbahn ein bewegliches Heizelement vorgeschaltet. Durch die Positionsveränderung des Heizelementes ist die Kontaktfläche zwischen dem Heizelement und der Trägerbahn stufenlos von null bis maximal veränderbar. Damit kann in vorteihafter Weise die Erwärmzeit der Geschwindigkeit der Trägerbahn angepaßt werden.In an expedient embodiment, the guide element a movable heating element connected upstream for the carrier web.

Die Vorrichtung zum Dekorieren besteht in der Hauptsache aus einer Transporteinrichtung für die Gebinde und aus einer Transporteinrichtung für die Dekors, die beide eine gemeinsame Schnittstelle für die Übertragung der Dekors auf die Gebinde besitzen.The device for decorating is mainly from a transport device for the containers and from a transport device for the decorations, both a common interface for the transmission of the Own decorations on the containers.

Dazu ist gemäß der Fig. 1 die Transporteinrichtung für Gebinde als ein drehbares Karussell 1 ausgebildet. Das Karussell 1 besitzt einen nicht gezeigten Antrieb, eine Eingabestation 2, eine Ausgabestation 3 und eine Transportbahn 4 für die Gebinde 5. Auf der Transportbahn 4 sind in gleichen Abständen Aufnahmemittel 6 für die zu dekorierenden Gebinde 5 angeordnet. Diese Aufnahmemittel 6 sind freidrehend ausgeführt.1 is the transport device for Container designed as a rotatable carousel 1. The Carousel 1 has a drive, not shown, one Input station 2, an output station 3 and a transport track 4 for the container 5. On the transport track 4 are receiving means 6 for the at equal intervals decorating containers 5 arranged. This means of reception 6 are designed to rotate freely.

Die Transporteinrichtung für die Dekors besteht aus einer, durch einen nicht dargestellten Antrieb ziehend belasteten Trägerbahn 7 und entsprechenden Führungselementen für diese Trägerbahn 7. Die Trägerbahn 7 ist in bekannter Weise ausgebildet und trägt mittels eines Haftmittels mit geringerer Haftkraft in gleichen Abständen angeordnete Dekors. Die Oberflächen der Dekors sind mit einem anderen Haftmittel mit größerer Haftkraft überzogen.The transport device for the decor consists of a pulled by a drive, not shown Carrier track 7 and corresponding guide elements for this carrier web 7. The carrier web 7 is in known manner trained and carries by means of a Adhesive with lower adhesive strength at equal intervals arranged decorations. The surfaces of the decorations are with another adhesive with greater adhesive strength overdrawn.

Die Führungselemente bestehen aus mindestens einer Umlenkrolle 8, einem schwenkbaren Heizelement 9 und einem in Richtung der Gebinde 5 verschiebbaren Druckkopf 10. Das schwenkbare Heizelement 9 besitzt eine äußere Führungsfläche 12, die zweckmäßigerweise konvex ausgebildet ist und einen oberen Drehpunkt. Um diesen Drehpunkt ist das Heizelement 9 durch einen Antrieb herkömmlicher Art in Richtung quer zur Bewegungsrichtung der Trägerbahn 7 schwenkbar. Dadurch ergibt sich eine in der Größe unterschiedliche, vom Schwenkwinkel abhängige Kontaktfläche zwischen der Führungsfläche 12 und der Trägerbahn 7. Der Druckkopf 10 besitzt ebenfalls eine äußere, vorzugs-weise ebene Führungsfläche 11 und wird durch eine vorgespannte Druckfeder oder durch ein anderes herkömmliches Antriebssystem in Richtung des Karussells 1 angetrieben. Die Transportbahn 4 für die Gebinde 5 und die Trägerbahn 7 für die Dekors tangieren einander im Bereich des Druckkopfes 10, wobei die Bewegungen der Transportbahn 4 und der Trägerbahn 7 entgegengerichtet sind. Somit kommt es in diesem Bereich zum direkten Kontakt zwischen der Trägerbahn 7 und den Gebinden 5 und damit auch mit den freidrehbaren Aufnahmemittel 6.The guide elements consist of at least one deflection roller 8, a pivotable heating element 9 and one Printhead 10 slidable in the direction of the container 5. The pivotable heating element 9 has an outer guide surface 12, which is expediently convex is and an upper pivot. Around that pivot point the heating element 9 by a drive of conventional type in the direction transverse to the direction of movement of the carrier web 7 pivotable. This results in a different size, contact surface dependent on the swivel angle between the guide surface 12 and the carrier web 7. The print head 10 also has an outer, preferably flat guide surface 11 and is biased by a Compression spring or by another conventional Drive system driven in the direction of the carousel 1. The transport track 4 for the container 5 and the carrier track 7 for the decorations affect each other in the area of Print head 10, the movements of the transport path 4 and the carrier web 7 are opposite. Thus comes it in this area for direct contact between the Carrier web 7 and the container 5 and thus also with the freely rotatable receiving means 6.

Wie die Fig 2 zeigt, kann in einer besonderen Weise in Bewegungsrichtung der Trägerbahn 7 nach dem Druckkopf 10 eine Umlenkrolle 13 angeordnet sein. Dabei liegt der Standort der Umlenkrolle 13 außerhalb der Transportbahn 4 in einem Abstand vom Druckkopf 10, der größer ist als der Abstand der Gebinde 5, wodurch es zum Kontakt der vom Dekor befreiten Trägerbahn 7 und dem nächsten Gebinde 5 kommt.As shown in Fig. 2, in a special way Direction of movement of the carrier web 7 after the print head 10 a deflection roller 13 may be arranged. Here lies the Location of the deflection roller 13 outside the transport path 4 at a distance from the printhead 10 that is greater than the distance of the container 5, which makes it to contact the Carrier web 7 freed from the decor and the next container 5 is coming.

Gemäß der Fig. 3 besteht das Führungselement für die Trägerbahn 7 aus dem Druckkopf 10' und dem Heizelement 9'. Beide sind feststehend zueinander ausgebildet. Der Druckkopf 10' besitzt eine äußere Führungsfläche 11', eine mechanische Voreinstelleinrichtung 14 und einen pneumatischen Antrieb 15.3 there is the guide element for the Carrier web 7 from the print head 10 'and the heating element 9 '. Both are fixed to each other. The Print head 10 'has an outer guide surface 11', a mechanical preset 14 and one pneumatic actuator 15.

Das Heizelement 9' ist mit einer äußeren, konvexen Führungsfläche 12' ausgerüstet und besitzt eine Wirkverbindung mit einem Schwenkarm 16. Dieser Schwenkarm 16 ist an seinem Kopf mit einer Umlenkrolle 17 und mit einer Abstandsrolle 18 ausgerüstet. Der Schwenkarm 16 besitzt weiterhin einen nicht dargestellten Antrieb, mit dem die Position der Umlenkrolle 17 gegenüber dem Heizelement 9' veränderbar ist. Diese Position wird in Abhängigkeit von der Geschwindigkeit der Trägerbahn 7 eingestellt und bestimmt die Größe der Kontaktfläche zwischen dem Heizelement 9' und der Trägerbahn 7. Bei einer langsamen Geschwindigkeit positioniert sich die Umlenkrolle 17 näher und bei einer schnellen Geschwindigkeit weiter vom Druckkopf 10' entfernt. Die Abstandsrolle 18 hält die Trägerbahn 7 im Bereich vor der Umlenkrolle 17 von dem Heizelement 9' fern.The heating element 9 'has an outer, convex guide surface 12 'equipped and has an operative connection with a swivel arm 16. This swivel arm 16 is on his head with a pulley 17 and with one Spacer roller 18 equipped. The swivel arm 16 has continue a drive, not shown, with which the Position of the deflection roller 17 relative to the heating element 9 ' is changeable. This position is dependent on the speed of the carrier web 7 set and determined the size of the contact area between the heating element 9 'and the carrier web 7. At a slow speed the deflection roller 17 is positioned closer and at a fast speed further from Printhead 10 'removed. The spacer roller 18 holds the Carrier web 7 in the area in front of the deflection roller 17 of the Heating element 9 'remote.

Die Trägerbahn 7' befindet sich in der Position, wenn die nicht dargestellte Rolle mit der Trägerbahn 7 abgelaufen ist.The carrier web 7 'is in the position when the roll, not shown, with the carrier web 7 expired is.

Die Wärmenachbehandlungseinrichtung nach der Fig. 4 besteht aus einer feststehenden und elektrisch betriebenen Wärmeplatte 19 und einem, auf eine Sollwerttemperatur einstellbaren Regler 20 und ist hinter dem Übertragungsort eingerichtet. Die Wärmeplatte 19 kann mit einer planen oder mit einer konkaven Wärmefläche 21 ausgerüstet sein, die sich danach richten sollte, ob die Transportrichtung der Gebinde 5 eine lineare oder eine Kreisbahn beschreibt. Wird beispielsweise die Transportbahn 4 des Karussells 1 auch für die Wärmenachbehandlung der Gebinde 5 verwendet, ist eine konkav ausgeformte Wärmefläche 21 vorteilhaft. Bei der richtigen Wahl der Form der Wärmefläche 21 kann über die Länge der Wärmefläche 21 eine bestimmte Wärmenachbehandlungszeit definiert werden.The heat aftertreatment device according to FIG. 4 exists from a fixed and electrically operated Heat plate 19 and one, to a setpoint temperature adjustable controller 20 and is behind the transfer location set up. The hot plate 19 can plan with one or equipped with a concave heating surface 21 that should depend on whether the transport direction the container 5 is a linear or a circular path describes. For example, the transport path 4 of the Carousels 1 also for heat treatment of the containers 5 used is a concave shaped heat surface 21 advantageous. With the right choice of the shape of the heating surface 21 can over the length of the heating surface 21 certain heat treatment times can be defined.

Als Antrieb für die Rotation der Gebinde 5 wird vorzugsweise wieder die auftretende Reibung zwischen den sich bewegenden Gebinden 5 und der feststehenden Wärmeplatte ausgenutzt. As a drive for the rotation of the container 5 is preferred again the occurring friction between the moving container 5 and the fixed heating plate exploited.

Eine Wärmenachbehandlungseinrichtung nach der Fig. 5 besteht in der Hauptsache aus einem Düsenkopf 22, einem temperaturgeregelten Heißluftgenerator 23, einem mengengerègelten Bypassventil 24 und einem Temperatur- und Mengenregler 25.A heat treatment device according to FIG. 5 exists mainly from a nozzle head 22, one temperature-controlled hot air generator 23, a volume-controlled Bypass valve 24 and a temperature and Flow regulator 25.

Die Gebinde 5 befinden sich wieder auf einer linearen oder einer Kreisbahn. Für die Rotation der Gebinde 5 ist ein gesonderter Antrieb erforderlich.The containers 5 are again linear or linear Circular path. For the rotation of the container 5 is a separate one Drive required.

Der Sollwert der Temperatur für den Regler 20 oder für den Temperatur- und Mengenregler 25 ist unter Berücksichtigung des Materials der Gebinde 5 vorzugeben. Gebinde 5 aus Kunststoff bedürfen daher einer besonderen Aufmerksamkeit. Zur Vermeidung von unerwünschten Deformationen ist es unter Umständen angebracht, Gebinde 5 aus Kunststoff zusätzlich mit eingeblasener Preßluft zu stabilisieren.The setpoint temperature for controller 20 or for the temperature and quantity controller 25 is taken into account to specify the material of the container 5. container 5 made of plastic therefore require a special one Attention. To avoid undesirable deformations it may be appropriate to use container 5 made of plastic additionally with injected compressed air stabilize.

Die Wirkungsweise der Vorrichtung wird an Hand der Fig. 1 erläutert.The operation of the device is based on the Fig. 1 explains.

Das Karussell 1 und die Trägerbahn 7 werden mit jeweils gewünschten aber konstanten Geschwindigkeiten angetrieben. Die Bewegungen sind dabei entgegengesetzt ausgerichtet. Die von der Eingabestation 2 auf die Aufnahmemittel 6 abgestellten Gebinde 5 werden auf der Transportbahn 4 in Richtung des Druckkopfes 10 transportiert. Gleichzeitig bewegen sich die am Heizelement 9 auf die notwendige Temperatur erwärmten Dekors auf der Trägerbahn 7 in entgegengesetzter Richtung auf den Druckkopf 10 zu.The carousel 1 and the carrier web 7 are each with desired but constant speeds driven. The movements are oriented in opposite directions. The from the input station 2 to the recording means 6 parked containers 5 are on the conveyor 4 transported in the direction of the print head 10. At the same time move on the heating element 9 on the necessary temperature heated decor on the carrier web 7 in the opposite direction to the printhead 10 to.

Durch den Kontakt, der sich zwischen jedem Gebinde 5 und der Trägerbahn 7 im Bereich des Druckkopfes 10 einstellt, kommt es zur Rotation des auf dem Aufnahmemittel 6 frei drehbaren Gebindes 5. Dabei stellt sich am Gebinde 5 eine Umfangsgeschwindigkeit in der Größe der Geschwindigkeit der Trägerbahn 7 ein. Das Gebinde 5 wälzt auf der Trägerbahn 7 unter dem Druck, der vom Druckkopf 10 ausgeht, ab. Dabei löst sich das Dekor von der Trägerbahn und haftet sich an das Gebinde 5.Due to the contact between each container 5 and the carrier web 7 adjusts in the area of the print head 10, there is a rotation of the on the receiving means 6 freely rotatable container 5. This turns on the container 5 a peripheral speed in the size of the speed the carrier web 7 a. The container 5 rolls on the carrier web 7 under the pressure exerted by the print head 10 goes out. The decor separates from the carrier web and adheres to the container 5.

Anschließend durchlaufen die Gebinde 5 eine der Wärmenachbehandlungseinrichtungen. The containers 5 then pass through one of the heat treatment devices.
