Description

Die Erfindung betrifft eine Tampondruckmaschine, mit einer Einfärbevorrichtung und einem in einem Gehäuse hin- und herbewegbaren Schlitten, an dem eine Druckeinrichtung mit einem Druckkissen angebracht ist und der mittels eines Antriebs horizontal zur Farbaufnahme und -abgabe zwischen einer ersten und einer zweiten Position verfahrbar ist.The invention relates to a tampon printing machine, with a inking device and a carriage which can be moved back and forth in a housing, to which a printing device with a pressure pad is attached and which can be moved horizontally between a first and a second position by means of a drive for ink absorption and delivery.

Eine Tampondruckmaschine dieser Art ist durch die CH-A-527 699 bekannt. Mit dieser ist es möglich, ebene und auch unebene Gegenstände auf einfache Weise zu bedrucken. Das Druckkissen, auch Tampon genannt, wird nach dem Einfärben eines Klischees auf dieses aufgepresst, vertikal angehoben und an zwei parallel verlaufenden Führungssäulen horizontal verschoben, bis das Druckkissen sich über dem zu bedruckenden Gegenstand befindet. Mit einer vertikalen Bewegung des Druckkissens wird dann der Gegenstand bedruckt. Mit der horizontalen Bewegung des Druckkissens ist eine ebenfalls horizontale Bewegung einer Einfärbevorrichtung gekoppelt. Es hat sich gezeigt, dass eine Tampondruckmaschine mit stillstehendem Klischee für die Bedienung günstiger ist als eine beispielsweise aus der DE-B-1 923 374 bekannte Tampondruckmaschine mit einem zu bewegenden Klischee. Eine Tampondruckmaschine mit stillstehendem Klischee zeigt ebenfalls die EP-B-0 086 742. Bei dieser wird das Druckkissen zum Bedrucken eines Gegenstandes jedoch nicht horizontal verfahren, sondern um eine horizontale Achse verschwenkt.A pad printing machine of this type is known from CH-A-527 699. With this it is possible to print flat and uneven objects in a simple manner. After inking a cliché, the pressure pad, also called a tampon, is pressed onto it, lifted vertically and horizontally on two parallel guide columns moved until the pressure pad is over the object to be printed. The object is then printed with a vertical movement of the pressure pad. A horizontal movement of an inking device is coupled with the horizontal movement of the pressure pad. It has been shown that a pad printing machine with a stationary cliché is cheaper to operate than a pad printing machine known from DE-B-1 923 374, for example, with a cliché to be moved. A pad printing machine with a stationary cliché is also shown in EP-B-0 086 742. In this case, however, the pressure pad for printing an object is not moved horizontally, but is pivoted about a horizontal axis.

Bei der genannten gattungsgemässen Tampondruckmaschine mit stillstehendem Klischee und horizontal verfahrbarem Druckkissen besteht die Schwierigkeit, dass die Lagerung des Druckkissens im Hinblick auf die erforderliche Stabilität sehr aufwendig ist. Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Tampondruckmaschine der genannten Gattung zu schaffen, die wesentlich kostengünstiger herstellbar ist und die dennoch eine hohe Druckqualität gewährleistet.The above-mentioned generic tampon printing machine with a stationary cliché and horizontally movable pressure pad has the difficulty that the storage of the pressure pad is very complex with regard to the required stability. The invention is therefore based on the object of creating a tampon printing machine of the type mentioned which can be produced much more cost-effectively and which nevertheless ensures high print quality.

Die Aufgabe ist bei einer erfindungsgemässen Tampondruckmaschine dadurch gelöst, dass der Schlitten mit seiner Führung auf einer Grundplatte des Maschinen gehäuses befestigt ist und einen kastenförmigen und von der Grundplatte nach obenragenden Träger aufweist und die Druckeinrichtung an diesem Träger angebracht ist. Ein solcher Träger ist einerseits sehr kostengünstig und andererseits sehr stabil herstellbar. Die vergleichbare hohe Stabilität erlaubt es, die Führung des Schlittens auf einer Grundplatte anzuordnen. Dies ermöglicht eine wesentlich einfachere Montage als bisher. Infolge der hohen Stabilität und Festigkeit des Trägers ist gewährleistet, dass auch bei schnellen horizontalen Hubbewegungen das Druckkissen schwingungsarm gehalten ist.The object is achieved in a tampon printing machine according to the invention in that the carriage is fastened with its guide on a base plate of the machine housing and has a box-shaped carrier which projects upwards from the base plate and the printing device is attached to this carrier. Such a carrier is on the one hand very inexpensive and very stable to manufacture. The comparable high stability allows the slide to be arranged on a base plate. This enables a much easier assembly than before. As a result of the high stability and strength of the carrier, it is ensured that the pressure cushion is kept low-vibration even with rapid horizontal lifting movements.

Nach einer Weiterbildung der Erfindung ist die Einfärbevorrichtung ebenfalls am Träger angebracht. Mit der horizontalen Bewegung des Schlittens werden somit das Druckkissen und die Einfärbevorrichtung gleichzeitig bewegt. Eine solche Ausführung ist besonders kostengünstig, da mit einem einzigen Antrieb das Druckkissen und die Einfärbevorrichtung horizontal bewegt werden können und gleichzeitig ein aufwendiges Uebersetzungsgetriebe nicht erforderlich ist. Die Montage ist besonders einfach, da der Schlitten mit seiner Führung und die Einfärbevorrichtung auf einer Grundplatte der Maschine montiert werden können. Das Maschinengehäuse kann ebenfalls sehr kostengünstig aus Blech hergestellt werden, da an diesem keine Führungsstangen oder Schienen gelagert werden müssen.According to a development of the invention, the coloring device is also attached to the carrier. With the horizontal movement of the carriage, the pressure pad and the inking device are thus moved simultaneously. Such an embodiment is particularly cost-effective since the pressure pad and the inking device can be moved horizontally with a single drive and, at the same time, an expensive transmission gear is not required. Installation is particularly simple since the slide with its guide and the coloring device can be mounted on a base plate of the machine. The machine housing can also be produced very cheaply from sheet metal, since no guide rods or rails have to be mounted on it.

Eine besonders stabile und dennoch einfache Ausführung ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung der Schlitten U-förmig ausgebildet ist und die beiden Schenkel horizontal ausgerichtet und übereinander angeordnet sind. Am oberen Schenkel des Schlittens ist bei dieser Ausführung die Druckeinrichtung angebracht, während am anderen Schenkel die Einfärbevorrichtung befestigt ist. Vorzugsweise befindet sich die Angriffsstelle des Antriebs am Schlitten, während die Führung des Schlittens an der Unterseite dieses Schenkels angeordnet ist. Dies ermöglicht eine sehr günstige Kraft- und Bewegungsübertragung.A particularly stable, yet simple design is obtained if, according to a development of the invention, the slide is U-shaped and the two legs are aligned horizontally and arranged one above the other are. In this embodiment, the printing device is attached to the upper leg of the carriage, while the inking device is attached to the other leg. The point of engagement of the drive is preferably on the slide, while the guide of the slide is arranged on the underside of this leg. This enables a very cheap transmission of power and movement.

Die in den Figuren 1 bis 3 gezeigte Tampondruckmaschine weist eine Grundplatte 1 auf, auf der ein Maschinengehäuse 2 aus Blech, ein Schlitten 45, ein Farbbehälter 22 sowie ein Klischee 23 angeordnet sind. Der Schlitten ist in den Richtungen des Doppelpfeils 32 horizontal mittels einer Zylinder-Kolben-Einheit 25 bewegbar. Ein zu bedruckender Gegenstand 3 ist im Abstand zur Grundplatte 1 so angeordnet, dass in der Position des Schlittens 45 gemäss Fig. 1 ein am Schlitten 45 angebrachtes Druckkissen 39 mittels einer vertikalen Bewegung an diesen anpressbar ist.The pad printing machine shown in FIGS. 1 to 3 has a base plate 1 on which a machine housing 2 made of sheet metal, a slide 45, an ink container 22 and a plate 23 are arranged. The carriage can be moved horizontally in the directions of the double arrow 32 by means of a cylinder-piston unit 25. An object 3 to be printed is arranged at a distance from the base plate 1 such that, in the position of the carriage 45 according to FIG. 1, a pressure pad 39 attached to the carriage 45 can be pressed against it by means of a vertical movement.

Der Schlitten 45 besteht im wesentlichen aus einem U-förmigen Träger 8, an dem unterseitig mittels einer Platte 17 und Befestigungsschrauben 7 eine Führung 6 mit einer sich horizontal erstreckenden Führungsnut fest angebracht ist. Die Führung 6 sitzt auf einer Führungsschiene 4, die mittels Befestigungsschrauben 5 an der Grundplatte 1 fixiert ist. Der Schlitten 45 ist auf der Schiene 4 mittels einer doppelwirkenden Zylinder-Kolben-Einheit 25 begrenzt in den Richtungen des Pfeils 32 hin- und herbewegbar. Diese Einheit 25 weist hier nur andeutungsweise gezeigte übliche Anschlüsse 26 auf und ist am einen Ende mittels einer Halterung 29 fest mit der Grundplatte 1 und am freien Ende des Kolbens 27 mittels eines Gelenks 28 an einem unteren Schenkel 9 eines Trägers 8 angelenkt. Die Einheit 25 ist vorzugsweise pneumatisch betätigt, jedoch kann diese Einheit auch durch einen anderen geeigneten Antrieb und insbesondere durch einen Handantrieb ersetzt sein.The carriage 45 consists essentially of a U-shaped carrier 8, on the underside of which a guide 6 with a horizontally extending guide groove is firmly attached by means of a plate 17 and fastening screws 7. The guide 6 sits on a guide rail 4 which is fixed to the base plate 1 by means of fastening screws 5. The carriage 45 can be moved back and forth on the rail 4 by means of a double-acting cylinder-piston unit 25 in the directions of the arrow 32. This unit 25 has only typical connections 26 shown here and is articulated at one end by means of a holder 29 to the base plate 1 and at the free end of the piston 27 by means of a joint 28 to a lower leg 9 of a carrier 8. The unit 25 is preferably pneumatically operated, but this unit can also be replaced by another suitable drive and in particular by a manual drive.

Am vorderen Ende des Schenkels 9 ist eine beispielsweise aus der EP-B-0 026 742 bekannte Einfärbevorrichtung 18 befestigt. Diese kann mittels einer pneumatischen doppelwirkenden Zylinder-Kolben-Einheit 30 um eine Achse 40 verschwenkt werden. Die Anschlüsse dieser Einheit 30 sind hier ebenfalls schematisch gezeichnet und mit den Bezugszeichen 31 versehen. Diese Einheit 30 ist am hinteren Ende gemäss Fig. 1 am Träger 8 des Schlittens 45 angelenkt. Diese Einheit 30 wird somit mit dem Schlitten 45 mitbewegt. Die Einfärbevorrichtung weist ein Rakelmesser 20 sowie einen Spachtel 19 auf. Das Rakelmesser 20 und der Spachtel 19 sind mittels einer Rändelschraube 21 an der Einfärbevorrichtung montiert. Wird der Schlitten 45 in Fig. 1 horizontal nach links bewegt, so streift das Rakelmesser 20 vom Klischee 23 überschüssige Farbe weg. Wird hingegen der Schlitten 45 in Fig. 2 nach rechts bewegt, so entnimmt der Spachtel 19 aus dem Farbbehälter 22 Farbe und verteilt sie über das Klischee 23.A coloring device 18, known for example from EP-B-0 026 742, is attached to the front end of the leg 9. This can be pivoted about an axis 40 by means of a pneumatic double-acting cylinder-piston unit 30. The connections of this unit 30 are also shown schematically here and provided with the reference number 31. This unit 30 is articulated at the rear end according to FIG. 1 on the carrier 8 of the carriage 45. This unit 30 is thus moved with the carriage 45. The inking device has a doctor blade 20 and a spatula 19. The doctor blade 20 and the spatula 19 are mounted on the inking device by means of a knurled screw 21. If the carriage 45 is moved horizontally to the left in FIG. 1, the doctor blade 20 strips excess ink away from the cliché 23. On the other hand, if the carriage 45 is moved to the right in FIG. 2, the spatula 19 takes paint from the paint container 22 and distributes it over the cliché 23.

Der Farbbehälter 22 kann zusammen mit dem Klischee 23 mittels einer Einstellschraube 24 sowie einer weiteren hier nicht gezeigten zweiten Einstellschraube horizontal genau auf das Druckkissen 39 ausgerichtet werden.The ink container 22 can be aligned horizontally precisely with the printing block 39 by means of an adjusting screw 24 and a further second adjusting screw (not shown here) on the pressure pad 39.

Der untere Schenkel 9 des Trägers 8 ist über einen vertikal verlaufenden Trägerteil 11 fest mit einem oberen Schenkel 10 verbunden, der durch eine Oeffnung 43 einer frontseitigen Wandung 46 des Maschinengehäuses 2 nach aussen ragt. Wie die Fig. 3 deutlich zeigt, weisen die Schenkel 9 und 10 jeweils eine Abdeckplatte 12 bzw. 13 auf, die an einem im Querschnitt U-förmigen Bereich des Schenkels 9 bzw. 10 befestigt, beispielsweise angenietet sind. Die Schenkel 9 und 10 sind somit jeweils für sich kastenförmig aus Blech hergestellt und bilden jeweils für sich stabile Teile des Trägers 8. Der obere Schenkel 10 ist etwas länger als der untere Schenkel 9 und trägt oberseitig am vorderen Ende einen an sich bekannten Maschinenteil 34, in dem eine Zylinder-Kolben-Einheit 36 zur Ausübung eines vertikalen Hubes des Druckkissens 39 untergebracht ist. Die doppelwirkende Einheit 36 ist selbstverständlich über Anschlüsse 35 in bekannter Weise mit hier nicht gezeigten pneumatischen Ventilen verbunden. Ein Kreuzschlitten 38, der die Einheit 36 mit dem Druckkissen 39 verbindet, ermöglicht ein horizontales Ausrichten des Druckkissens 39.The lower leg 9 of the carrier 8 is fixedly connected via a vertically running support part 11 to an upper leg 10 which projects outwards through an opening 43 in a front wall 46 of the machine housing 2. As FIG. 3 clearly shows, the legs 9 and 10 each have a cover plate 12 or 13, which are fastened, for example riveted, to a region of the leg 9 or 10 which is U-shaped in cross section. The legs 9 and 10 are thus each box-shaped made of sheet metal and each form stable parts of the carrier 8. The upper leg 10 is somewhat longer than the lower leg 9 and carries a machine part 34 known per se at the front end. in which a cylinder-piston unit 36 for accommodating a vertical stroke of the pressure pad 39 is accommodated. The double-acting unit 36 is of course connected via connections 35 in a known manner to pneumatic valves, not shown here. A cross slide 38, which connects the unit 36 to the pressure pad 39, enables the pressure pad 39 to be aligned horizontally.

In der Position gemäss Fig. 1 bewegt die Einheit 36 das Druckkissen 39 zum Bedrucken des Gegenstandes 3 vertikal nach unten. Die hierbei auf die Einheit 36 ausgeübte Gegenkraft wird über den oberen Schenkel 10 auf den vertikalen Trägerteil 11 und von diesem auf die Schlittenführung sowie schliesslich auf die Grundplatte 1 übertragen. Die Grundplatte 1 kann selbstverständlich auf einem Tisch oder dergleichen befestigt sein. Die bereits oben erwähnte hohe Stablität des Trägers 8 erlaubt diese Kraftübertragung ohne wesentliche Formänderungen des Schlittens 45.In the position according to FIG. 1, the unit 36 moves the pressure pad 39 vertically downwards for printing on the object 3. The counterforce exerted on the unit 36 is transmitted via the upper leg 10 to the vertical support part 11 and from there to the slide guide and finally to the base plate 1. The base plate 1 can of course be attached to a table or the like. The already mentioned high stability of the carrier 8 allows this power transmission without significant changes in the shape of the slide 45.

Der Träger 8 besteht aus zwei Teilen 8a und 8b, die entlang einer vertikalen Ebene 8c fest miteinander verbunden, beispielsweise verschweisst sind. Die Teile 8a und 8b können aus einem gestanzten Metallblech durch Abkanten in einfacher Weise und sehr kostengünstig hergestellt werden. Ausgestanzte Oeffnungen 14, 15 und 16 dienen für den Durchgang von Leitungen. Auf der Rückseite kann der Träger 8 offen sein. Zu seiner Herstellung können irgendwelche geeignete Bleche verwendet werden, wobei hier auch Verbundmaterialien oder Bleche aus nichtmetallischen geeigneten Stoffen denkbar sind. Zur Erhöhung der Stabilität des Trägers 8 ist auch ein Ausschäumen oder anderweitiges Verstärken dieses Trägers 8 denkbar.The carrier 8 consists of two parts 8a and 8b, which are firmly connected to one another along a vertical plane 8c, for example welded. The parts 8a and 8b can be produced from a stamped metal sheet by folding in a simple manner and very inexpensively. Punched out openings 14, 15 and 16 are used for the passage of lines. The carrier 8 can be open on the back. Any suitable metal sheets can be used for its production, although composite materials or metal sheets made of non-metallic materials are also conceivable here. To increase the stability of the support 8, foaming or other reinforcement of this support 8 is also conceivable.

Die Fig. 4 zeigt eine Ausführung der erfindungsgemässen Tampondruckmaschine, bei welcher ein L-förmiger Träger 52 mit einem Schenkel 53 und einem vertikalen Trägerteil 54 vorgesehen ist. Dieser Träger 52 ist wie oben beschrieben aus Blech hergestellt und wie der Träger 8 bzw. der Schlitten 45 auf einer Grundplatte 1 geführt und mittels einer Zylinder-Kolben-Einheit 25 begrenzt hin- und herbewegbar. Im Gegensatz zur oben beschriebenen Ausführung weist hier jedoch die Einfärbevorrichtung einen an sich bekannten Farbtopf 55 auf, der unten offen ist und der oben über ein Kugelgelenk 58 mit einer Zylinder-Kolben-Einheit 57 am Schenkel 53 befestigt ist. Das Klischee 51 wird durch hin-und herbewegen des Farbtopfes 55 und der darin befindlichen Farbe 56 in bekannter Weise eingefärbt. Da der Farbtopf 55 und auch das Druckkissen 39 fest mit dem Träger 52 bzw. dem Schlitten verbunden sind, werden diese immer gleichzeitig mit dem Schlitten bewegt. Denkbar ist auch eine Ausführung, bei welcher der Farbtopf 55 mit dem vertikalen Trägerteil 54 verbunden ist. Weiterhin ist eine Ausführung denkbar, bei der eine andere Einfärbevorrichtung vorgesehen ist. In einer sehr vereinfachten und kostengünstigen Ausführung kann schliesslich die Antriebseinheit 25 weggelassen und der Schlitten von Hand hin- und herbewegt werden. Des weiteren ist eine Ausführung denkbar, bei welcher das Klischee hin- und herbewegt und die Einfärbevorrichtung bezüglich des Maschinengehäuses 2 festgehalten ist. Bei dieser Ausführung wird somit lediglich die Druckeinrichtung 37 mit dem Schlitten bzw. dem Träger 52 hin- und herbewegt.4 shows an embodiment of the tampon printing machine according to the invention, in which an L-shaped support 52 with a leg 53 and a vertical support part 54 is provided. As described above, this support 52 is made of sheet metal and, like the support 8 or the slide 45, is guided on a base plate 1 and can be moved back and forth to a limited extent by means of a cylinder-piston unit 25. In contrast to the embodiment described above here however, the inking device has a known ink cup 55, which is open at the bottom and which is attached to the leg 53 at the top via a ball joint 58 with a cylinder-piston unit 57. The cliché 51 is colored in a known manner by moving the ink cup 55 and the ink 56 therein. Since the ink cup 55 and also the pressure pad 39 are firmly connected to the carrier 52 or the carriage, these are always moved simultaneously with the carriage. An embodiment is also conceivable in which the ink cup 55 is connected to the vertical support part 54. Furthermore, an embodiment is conceivable in which another coloring device is provided. In a very simplified and inexpensive embodiment, the drive unit 25 can finally be omitted and the carriage can be moved back and forth by hand. Furthermore, an embodiment is conceivable in which the cliché is moved back and forth and the inking device is held with respect to the machine housing 2. In this embodiment, only the printing device 37 is thus moved back and forth with the carriage or the carrier 52.
