Description

Die Erfindung betrifft eine Tampondruckmaschine mit wenigstens einem Behälter zum Einfärben einer Druckplatte, mit einer Anpressvorrichtung zum Anpressen des Behälters an die Druckplatte und mit einem Antrieb, um die Druckplatte und den Behälter zum Einfärben eines Klischees der Druckplatte relativ zueinander hin- und herzubewegen.The invention relates to a pad printing machine with at least a container for inking a printing plate, with a Pressing device for pressing the container onto the Pressure plate and with a drive to the pressure plate and the Container for inking a plate printing plate relative to move back and forth to each other.

Die Erfindung betrifft ebenfalls ein Verfahren für den Tampondruck, bei dem mit einem unten offenen Behälter ein Klischee eingefärbt und mit einem Tampon Druck- oder Teilbilder auf ein Werkstück übertragen werden.The invention also relates to a method for pad printing, a cliché with a container open at the bottom colored and with a tampon printed or partial images can be transferred to a workpiece.

Tampondruckmaschine und Verfahren der genannten Art sind im Stand der Technik gut bekannt. Diese weisen einen unten offenen Farbbehälter auf, der auf einer hin- und her beweglichen Tiefdruckplatte, auch Klischee genannt, aufliegt. Der Farbbehälter besitzt einen auf der Druckplatte anliegenden Rand mit einer keilförmig zugeschärften Kante. Bei gefülltem Farbbehälter wird bei einer Verschiebung der Druckplatte auf diese Farbe aufgetragen und gleichzeitig mit einer weiteren Verschiebebewegung abgerakelt. Mittels eines Tampons wird nach dem Farbauftrag das Druckbild auf ein Druckgut übertragen. Beim Einfärben wird der Behälter ständig gegen die Druckplatte gepresst, was beispielsweise mit einer Druckfeder erfolgen kann. Eine Tampondruckmaschine dieser Art ist beispielsweise durch die WO-93/11 943 bekannt geworden. In der Schweizerischen Patentanmeldung Nr. 03 481, 94-4 vom 18. November 1994 ist vom Anmelder ein Verfahren und eine Vorrichtung für den Tampondruck vorgeschlagen worden, bei welchem der Behälter beim Einfärben um eine vertikale Achse gedreht wird. Bei dieser Tampondruckmaschine besteht unter anderem der Vorteil, dass der Pressdruck des Behälters an der Oberfläche des Klischees vermindert werden kann. Die Abnutzung des Rakelrandes und des Klischees ist damit geringer als bisher. Auf diese noch nicht veröffentlichte Anmeldung wird in dieser vorliegenden Anmeldung Bezug genommen.Pad printing machine and method of the type mentioned are in Well known in the art. These have an open bottom Paint container on which is moving back and forth Gravure plate, also called cliché, rests. The paint container has a border on the printing plate with a wedge-shaped edge. When the paint container is full is when the pressure plate is moved to this Paint applied and at the same time with a further shifting movement doctored. Using a tampon transfer the print image to a print item after the ink application. When inking, the container is constantly against the pressure plate pressed, which can be done with a compression spring, for example can. A pad printing machine of this type is for example made known by WO-93/11 943. In the Swiss Patent Application No. 03 481, 94-4 dated November 18, 1994 is a process and an apparatus for the Pad printing has been proposed in which the container is rotated around a vertical axis during coloring. At this Pad printing machine has the advantage, among other things, that the press pressure of the container on the surface of the cliché can be reduced. Wear of the squeegee edge and the cliché is less than before. To this Not yet published application is present in this Registration referred.

Der Erfindung liegt die Aufgabe zugrunde, eine Tampondruckmaschine und ein Verfahren für den Tampondruck zu schaffen, die sich durch eine noch höhere Lebensdauer und höhere Druckqualität auszeichnen.The invention has for its object a pad printing machine and to create a process for pad printing that through an even longer lifespan and higher print quality award.

Die Aufgabe ist bei einer erfindungsgemässen Tampondruckmaschine dadurch gelöst, dass beim Einfärben die relative Lage des Behälters zur Längsachse des Klischees und damit zum Druckbild durch eine weitere relative Bewegung geändert wird. Das erfindungsgemässe Verfahren ist dadurch gekennzeichnet, dass der Behälter beim Einfärben sich an seinem Rand nicht auf einer geraden Linie bewegt, sondern regelmässig oder unregelmässig an seinem äussersten Bereich eine Fläche überstreicht.The object is in a pad printing machine according to the invention solved by coloring the relative position of the container to the longitudinal axis of the cliché and thus to Print image is changed by another relative movement. The method according to the invention is characterized in that that the container does not stick to its edge when it is colored moved on a straight line, but regularly or irregularly covers an area at its outermost area.

Die erfindungsgemässe Tampondruckmaschine und das Verfahren zeichnen sich durch folgende Vorteile aus. Der Behälter und das Klischee können sich auch nach langer Betriebsdauer nicht aufeinander einschleifen. Bei gleichem Behälter kann deshalb das Klischee ohne weiteres gegen ein anderes Klischee ausgetauscht werden. Bei gleichem Klischee kann zudem ohne weiteres der Behälter gegen einen anderen ausgetauscht werden. Die Druckplatte wird gleichmässiger abgenutzt, da die Druckplatte mit dem Klischee den Behälter jeweils in einem anderen Winkel anfährt. Sowohl der Behälter als auch das Klischee werden weniger abgenutzt. The pad printing machine according to the invention and the method are characterized by the following advantages. The container and the cliché cannot change even after a long period of operation grind on each other. With the same container, therefore exchanged the cliché for another cliché become. With the same cliché, it can also be done easily the container can be exchanged for another. The Pressure plate is worn more evenly because the pressure plate with the cliché the container at a different angle starts. Both the container and the cliché are becoming fewer worn.

Nach einer Weiterbildung der Erfindung ist die relative Bewegung oszillierend, schlingernd, schwingend, pendelnd oder stossend. Eine solche Bewegung wird nach einer Weiterbildung der Erfindung durch zwei Exzenter, die abhängig oder unabhängig voneinander Kreisbewegungen ausführen dem Behälter aufgezwungen. Die Exzenter können abhängig voneinander und in gleichen Schritten eine Kreisbewegung auf den Topf übertragen oder abhängig voneinander und in nicht gleichen Schritten je eine Kreisbewegung auf den Behälter übertragen und diesem eine oszillierende Bewegung aufzwingen. Schliesslich kann mit den beiden Exzentern unabhängig voneinander und in gleichen oder nicht gleichen Schritten eine Kreisbewegung auf den Behälter übertragen werden. Die Exzenter können beispielsweise mit jeweils einer drehenden Kolbenstange betätigt werden. Ein geeigneter Antrieb ist in der oben erwähnten Schweizerischen Patentanmeldung offenbart.According to a development of the invention, the relative movement oscillating, lurching, swinging, swinging or pushing. Such a move will be after further training the invention by two eccentrics that are dependent or independent from each other circular movements forced the container. The eccentrics can depend on each other and in Transfer a circular motion to the pot following the same steps or depending on each other and in different steps transferred a circular motion to the container and this one Forcing oscillating movement. Finally, with the two eccentrics independently and in the same or not same steps a circular motion on the container be transmitted. The eccentrics can, for example can be operated with a rotating piston rod. On suitable drive is in the Swiss mentioned above Patent application disclosed.

Denkbar ist auch eine Ausführung, bei welcher gemäss einer Weiterbildung der Erfindung der Behälter mit zwei linearen Antrieben in x- beziehungsweise y-Richtung vor- und zurückgestossen wird. Die erwähnten Bewegungen können abhängig oder unabhängig voneinander ausgeübt und im wesentlichen beliebig kombiniert werden.An embodiment is also conceivable in which according to a Development of the invention of the container with two linear Drives pushed forwards and backwards in the x and y directions becomes. The movements mentioned can be dependent or exercised independently and essentially arbitrarily be combined.

Der Behälter ist vorzugsweise unrund und vergleichsweise flach. Ist er länglich, so besteht der besondere Vorteil, dass das Klischee mit einer vergleichsweise kurzen Bewegung eingefärbt werden kann. Da der Behälter keine vollständige Drehbewegung ausüben muss, kann er ohne weiteres mit einer Leitung für die Zuführung von Druckfarbe verbunden werden. Bei einem sich endlos oder um einen grossen Winkel drehenden und kreisrunden Behälter wäre dies problematisch.The container is preferably out of round and comparatively flat. If it is elongated, there is the special advantage that the cliché with a comparatively short movement can be colored. Because the container is not a complete one Must perform rotational movement, he can easily with a Line for the supply of ink to be connected. With one that rotates endlessly or through a large angle and circular containers would be problematic.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung. Further advantageous features result from the dependent ones Claims, the description below and the Drawing.

Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

  • Figur 1 schematisch drei unterschiedliche Positionen eines Behälters auf einem Klischee beim Einfärben,
  • Figur 2 einen Schnitt entlang der Linie II-II der Figur 1,
  • Figur 3 schematisch eine Draufsicht auf einen Behälter gemäss einer Variante,
  • Figur 4 schematisch einen Behälter mit einem Antrieb nach einer Variante, und
  • Figuren 5 bis 7 schematisch weitere Ausführungen mit jeweils einem Linearantrieb.
  • Exemplary embodiments of the invention are explained in more detail below with reference to the drawing. Show it:
  • FIG. 1 shows schematically three different positions of a container on a cliché during inking,
  • FIG. 2 shows a section along the line II-II in FIG. 1,
  • FIG. 3 shows a schematic plan view of a container according to a variant,
  • Figure 4 schematically shows a container with a drive according to a variant, and
  • Figures 5 to 7 schematically further versions, each with a linear drive.
  • Die Figur 1 zeigt eine Druckplatte 2 mit einem hier nicht gezeigten Klischee, auf der ein Behälter 1 mit zwei vertikalen Stangen 9 angepresst wird. Wie die Figur 2 zeigt, liegt der Behälter 1 mit einer umlaufenden scharfen Kante 4 auf der Oberseite 3 der Druckplatte 2 an. Der Behälter 1 enthält Druckfarbe 5 oder ein anderes geeignetes Druckmedium, das über eine Leitung 24 laufend nachgefüllt werden kann. Wird jedoch Platte 2 mit einem hier nicht gezeigten Antrieb hin- und herbewegt, so wird die Druckfarbe 5 auf der Oberseite 3 der Druckplatte 2 aufgetragen und anschliessend abgerakelt. Dies ist an sich gut bekannt und braucht hier nicht näher erläutert zu werden.1 shows a pressure plate 2 with one not shown here Cliché on which a container 1 with two vertical Rods 9 is pressed. As shown in Figure 2, the Container 1 with a peripheral sharp edge 4 on the Top 3 of the pressure plate 2. The container 1 contains Ink 5 or other suitable media that can be continuously refilled via a line 24. Becomes however plate 2 with a drive not shown here and moves, the printing ink 5 on the top 3 the printing plate 2 applied and then doctored off. This is well known per se and does not need to be explained in more detail here to become.

    In einer Deckenwandung 6 des Behälters 1 sind im Abstand zueinander zwei Führungen 7 und 8 angeordnet, in denen jeweils ein Exzenter 9 drehbar gelagert ist. An jedem Exzenter 9 greift eine vertikale Stange 12 an, die jeweils unabhängig voneinander mit einem Antrieb 10 gedreht werden kann. Die Stangen 12 sind vorzugsweise Kolbenstangen, die gleichzeitig auf den Behälter 1 von oben einen Druck ausüben. Ein solcher Antrieb ist in der Schweizerischen Patentanmeldung Nr. 34 81/94 offenbart.In a top wall 6 of the container 1 are spaced apart two guides 7 and 8 arranged in each an eccentric 9 is rotatably mounted. On each eccentric 9 attacks a vertical rod 12, each independently can be rotated from each other with a drive 10. The Rods 12 are preferably piston rods that operate simultaneously exert pressure on the container 1 from above. Such a The drive is in Swiss Patent Application No. 34 81/94.

    Die Figur 1 zeigt drei Positionen a, b und c, welche der Behälter 1 beim Einfärben der Druckplatte einnimmt. Beim Einfärben ist die relative Bewegung zwischen dem Behälter 1 und der Druckplatte wesentlich. Bei der hier gezeigten Ausführung wird der Behälter 1 festgehalten und die Druckplatte 2 hin- und herbewegt. Denkbar ist jedoch auch eine Ausführung, bei welcher die Druckplatte festgehalten und der Behälter 1 hin- und herbewegt wird. In der Figur 1 sind die drei Positionen a, b und c lediglich aus zeichnerischen Gründen auseinandergezogen. Beim Einfärben werden beide Stangen 11 und 12 um ihre vertikale Drehachse gedreht. Die Exzenter 9 sind so gestellt, dass in der Position a das linke Ende 1a eine oszillierende Bewegung ausführt. Damit diese Bewegung dem Behälter 1 aufgezwungen werden kann, ist der linke Exzenter in einer Längsführung 7 geführt. Damit kann der diesem Exzenter gegenläufige Hub des anderen Exzenters ausgeglichen werden. Während dieser oszillierenden Bewegung wird der Behälter in Figur 1 nach rechts in die Position bewegt. Der Exzenter wird entsprechend in der Längsführung 7 verschoben. In der Position c, die der Position b seitlich anschliesst, ist nun das linke Ende 1a des Behälters 1 vergleichsweise ruhig, während das rechte Ende 1b oszilliert. Die Kante 4 des Behälters 1 bewegt sich somit nicht auf einer Linie, wie dies bei einem runden drehenden Topf der Fall wäre, sondern überstreicht eine Fläche f, wie dies in Figur 1 schematisch dargestellt ist. Die relative Lage des Behälters 1 zur Längsachse 25 der Druckplatte 2 beziehungsweise des Klischees verändert sich während des Einfärbens stetig. Die oszillierende Bewegung des Topfes 1 kann nun so eingerichtet werden, dass das Klischee den Behälter 1 jeweils in einem anderen Winkel anfährt und damit das Klischee gleichmässiger abgenutzt wird.Figure 1 shows three positions a, b and c, which of the container 1 when inking the printing plate. When coloring is the relative movement between the container 1 and the printing plate essential. In the version shown here the container 1 is held and the pressure plate 2 is and moved. However, a version is also conceivable which holds the pressure plate and the container 1 and being moved. The three positions are in FIG a, b and c just pulled apart for drawing reasons. When coloring, both rods 11 and 12 around their vertical axis of rotation rotated. The eccentrics 9 are placed that in position a the left end 1a is an oscillating one Movement. So that this movement of the container 1 can be forced, the left eccentric is in one Longitudinal guide 7 out. This means that the counter to this eccentric Stroke of the other eccentric can be compensated. While this oscillating movement becomes the container in figure 1 moved right into position. The eccentric will moved accordingly in the longitudinal guide 7. In position c, which adjoins position b, is now that left end 1a of the container 1 comparatively quiet while the right end 1b oscillates. The edge 4 of the container 1 thus does not move on a line like this with one round rotating pot would be the case, but sweeps over one Area f, as shown schematically in Figure 1. The relative position of the container 1 to the longitudinal axis 25 of the Printing plate 2 or the cliché changes steadily during coloring. The oscillating movement of the Pot 1 can now be set up so that the cliché the container 1 starts at a different angle and so that the cliché is worn more evenly.

    Bei der Ausführung nach Figur 3 ist ein Behälter 14 etwa in seiner Mitte 15 drehbar fixiert und im Abstand dazu mit einem Exzenter 16 versehen, der beim Einfärben eine Kreisbewegung ausführt. Damit kann dem Behälter 14 eine Pendelbewegung um die Mitte 15 aufgezwungen werden.In the embodiment according to FIG. 3, a container 14 is approximately in its center 15 rotatably fixed and at a distance from it with one Eccentric 16 provided a circular movement when coloring executes. This allows the container 14 to oscillate the middle 15 to be forced.

    Nach einer weiteren Ausführung gemäss Figur 4 sind zwei Linear-antriebe 22 und 23 vorgesehen, die jeweils mit einer Stange 18 beziehungsweise 19 in Richtung der Pfeile 20 beziehungsweise 21 auf einen Behälter 17 jeweils eine stossende Hin- und Herbewegung ausüben. Die Antriebe 22 und 23 sind selbstverständlich gelenkig mit dem Behälter 17 verbunden. Durch eine geeignete Steuerung der Antriebe 22 und 23 kann auf den Behälter 17 ebenfalls eine oszillierende Bewegung ausgeübt werden. Diese Bewegung kann aber auch schlingernd, schwingend, pendelnd oder stossend sein. Wesentlich ist auch hier, dass die Kante 4 eine Fläche überstreicht und sich damit weniger in die Oberseite 3 der Druckplatte 2 einarbeiten kann.According to a further embodiment in accordance with FIG. 4, there are two linear drives 22 and 23 provided, each with a rod 18 or 19 in the direction of arrows 20 or 21 a pushing back onto a container 17 and exercise locomotion. The drives 22 and 23 are self-evident hinged to the container 17. By a suitable control of the drives 22 and 23 can on the Container 17 also has an oscillating movement become. But this movement can also wobble, swing, swinging or pushing his. It is also important here that the edge 4 is a Sweeps over the surface and thus less in the top 3 can incorporate the pressure plate 2.

    Bei der Ausführung gemäss Figur 5 ist ein Behälter 25 etwa mittig mit einer vertikalen Stange 26 drehbar fixiert und im Abstand dazu mit einem Exzenter 27 in einem Langloch 28 begrenzt verschiebbar geführt. Der Exzenter 27 ist mit einem hier nicht gezeigten Antrieb in Richtung des Pfeils 29 drehbar. Beim Drehen des Exzenters 27 führt der Behälter 25 um seine Mitte eine Bewegung aus, die in der Figur 5 durch strichpunktierte Linien ausgedehnt ist. Diese Bewegung wird ausgeführt, während die Druckplatte zum Einfärben des Klischees linear bewegt wird. Der Exzenter 27 könnte durch einen hier nicht gezeigten Linearantrieb ersetzt sein, welcher im Abstand zur Stange 26 am Behälter 25 angreift und diesen quer zu seiner Ergänzungsrichtung hin- und herbewegt.In the embodiment according to FIG. 5, a container 25 is approximately centrally rotatably fixed with a vertical rod 26 and in Distance to this is limited by an eccentric 27 in an elongated hole 28 slidably guided. The eccentric 27 is with one Drive not shown here can be rotated in the direction of arrow 29. When the eccentric 27 is rotated, the container 25 moves around its middle a movement from that shown in Figure 5 dash-dotted lines is extended. This movement will executed while the printing plate for inking the cliché is moved linearly. The eccentric 27 could by one Linear drive, not shown here, can be replaced, which in Distance to the rod 26 engages the container 25 and this transversely moved back and forth to its complementary direction.

    Bei der Ausführung nach Figur 6 ist ein Behälter 30 mittig mit einem Exzenter 31 und im Abstand dazu mit zwei Längsführungen 32 versehen. Beim Drehen des Exzenters 31 wird der Behälter 30 in Richtung des Doppelpfeils 33 quer zur Längsrichtung des Behälters 30 hin- und herbewegt. Auch in diesem Fall kann der Exzenter 31 durch einen Linearantrieb oder einen anderen geeigneten Antrieb ersetzt sein.In the embodiment according to FIG. 6, a container 30 is in the middle with an eccentric 31 and at a distance from it with two longitudinal guides 32 provided. When rotating the eccentric 31, the container 30 in the direction of the double arrow 33 transversely to the longitudinal direction of the container 30 reciprocated. In this case, too can the eccentric 31 by a linear drive or another suitable drive must be replaced.

    Schliesslich zeigt die Figur 7 einen Behälter 34, der ebenfalls mittig einen Exzenter 35 aufweist. Der Behälter 34 ist mit zwei Längsführungen 36 versehen, derart, dass beim Drehen des Exzenters 35 der Behälter 34 in den Richtungen des Doppelpfeils 37 eine oszillierende Bewegung ausführt.Finally, FIG. 7 shows a container 34, which also has an eccentric 35 in the middle. The container 34 is provided with two longitudinal guides 36 such that when turning of the eccentric 35 of the container 34 in the directions of the double arrow 37 executes an oscillating movement.

    Die oben erwähnten Bewegungen können auch kombiniert werden. Unterschiedliche Bewegungen können auch zeitlich nacheinander ausgeführt werden. Als Antriebe eignen sich Exzenter und Linearantriebe besonders, denkbar sind aber auch andere Antriebe, mit denen der Behälter während des Einfärbens bewegbar ist. In allen Fällen hat die Bewegung des Behälters bei stillstehender Druckplatte eine Vergrösserung der eingefärbten Fläche zur Folge.The movements mentioned above can also be combined. Different movements can also take place one after the other be carried out. Eccentric and linear drives are suitable as drives special, but other drives are also conceivable, with which the container can be moved during coloring is. In all cases, the movement of the container has stationary printing plate an enlargement of the inked Area to result.

    Grundsätzlich ist die relative Bewegung zwischen dem Behälter und der Druckplatte wesentlich. Denkbar ist deshalb auch eine Ausführung, bei welcher nicht der Behälter, sondern die Druckplatte zusätzlich zur translatorischen Bewegung beispielsweise oszillierend bewegt wird. Die zusätzliche translatorische Bewegung ist vergleichsweise langsam, beispielsweise wird der Exzenter während einer Einfärbung einmal gedreht. Es sind auch langsamere oder schnellere Bewegungen vorgesehen.Basically, the relative movement between the container and the printing plate essential. One is therefore also conceivable Version in which not the container but the Printing plate in addition to the translational movement, for example is moved oscillating. The additional translational Movement is comparatively slow, for example the eccentric is rotated once during coloring. They are also slower or faster movements intended.
