Definitions
- the invention relates to a multicolor tampon printing device for printing workpieces along a circular, endless conveyor path, with at least two tampons (14) and at least two inking and doctoring devices and just as many holders (18) for receiving the workpieces (20), the tampons (14) and the holder (18) are arranged in vertically offset horizontal planes and are rotatable overall about vertical axes.
- a generic tampon device is known from DE-GM 91 03 235, in which several tampon devices are arranged in a star shape. This improves the accessibility to the printing devices.
- the workpieces carry a ring driven by a drive device from one stationary pad printing machine to the other. Each color is transferred to the workpieces with a different tampon.
- a multi-color tampon printing machine is already known from EP 05 44 176 A1, in which several tampons are arranged on a tampon carrier so as to be rotatable about a first axis.
- the clichés can be rotated on a cliché carrier about a second axis which is arranged parallel to the first.
- the tampon carrier and the cliché carrier paint over a common position in which the tampons remove color from the clichés.
- the tampons apply the ink to the printed matter after a 90 ° turn.
- the printed material remains in this position until all colors, here four, have been transferred.
- This device already takes too much time to transmit four colors.
- the transfer of the individual colors causes irregularities in fit due to the different elasticity of different tampons.
- the printing device known from US-PS 36 88 695 works with thermoplastic inks. Two rotary tables are provided for this. One on which the colors are heated and successively applied to a support in the form of a membrane; and a second eight-station turntable on which the colors are transferred to the article by pivoting the frame in which the membranes are clamped by 180 ° between a station on the first turntable and a station on the second turntable.
- This system is not suitable for large quantities and, due to its double turntable arrangement, involves greater mechanical effort.
- a tampon printing device which has four tampons offset by 90 ° on a turnstile. Either the matrices or the supports for the objects to be printed are arranged diametrically opposite each other. After every 90 ° cycle of the turnstile, an object is printed, whereby the objects are not constantly printed by the same, but by one of the four existing tampons.
- GB-PS 804 751 relates to a multi-color screen printing device with, for example, four screens arranged in a circular or linear manner. All four colors are applied one after the other by moving the screens on a carrier. This carrier then moves from the screen area under a tampon, which picks up the entire color sample and transfers it to an object.
- the performance of the device is very limited due to its workflow.
- the object of the invention is to increase the transmission accuracy and the performance of the multi-color printing press.
- each individual color is transferred from one and the same tampon to the respective workpiece during a multicolour printing process. This creates a high register accuracy. There is also the advantage of the high performance of this device. After a separate transmission station is provided for each color, there is no waiting time, but a continuous cycle with a high frequency.
- Fig. 1 shows the pad printing device with a rotary table 10, which has upper holding arms 12 for the tampons 14 and lower holding arms 16 for the holder 18 in two planes.
- the workpieces 20 arrive individually or stacked on a conveyor belt 22 at a transfer 24.
- This transfer takes a workpiece 20, here for example a plate, and places it on the conveyor belt 26 after a 180 ° swiveling movement.
- the plates then cycle from a dusting device 28 into a floor stamping device 30, which works in the screen printing process.
- the linearly movable transfer 34 places the plates on the holder 18, where it is held in place by means of negative pressure.
- the multi-color pad printing device has a stand 36 which accommodates the drive (not shown).
- the holders 18 are attached to the ends of the eight holding arms 16.
- the center of the holder 18 and the center or the longitudinal central axis of the tampons 14 lie on the respective common axis A.
- the tampon 14 in FIG. 1 on the right takes up color from the scraped-off engraving plate of the doctoring and inking device 38 and gives it to the surface the plate 20 off.
- the tampon 14 with the piston-cylinder unit 40 rises and falls.
- the guides 42, 44 located on the side next to the piston-cylinder unit 40 ensure the exact central transfer of the six different colors. Every color is applied in so-called direct printing.
- Each plate is assigned the same tampon when each of the six colors is transferred.
- the linear transport device 46 carries the plates onto the conveyor belt 48.

Description
Die Erfindung betrifft eine Mehrfarben-Tampondruckvorrichtung zum Bedrucken von Werkstücken entlang einer kreisbahnförmigen, endlosen Förderbahn, mit mindestens zwei Tampons (14) und mindestens zwei Einfärbe- und Abrakelvorrichtungen und ebenso vielen Haltern (18) zur Aufnahme der Werkstücke (20), wobei die Tampons (14) und die Halter (18) in vertikal zueinander versetzten horizontalen Ebenen angeordnet und insgesamt um vertikale Achsen drehbar sind.The invention relates to a multicolor tampon printing device for printing workpieces along a circular, endless conveyor path, with at least two tampons (14) and at least two inking and doctoring devices and just as many holders (18) for receiving the workpieces (20), the tampons (14) and the holder (18) are arranged in vertically offset horizontal planes and are rotatable overall about vertical axes.
Aus dem DE-GM 91 03 235 ist eine gattungsmäßige Tamponvorrichtung bekannt, bei der mehrere Tamponvorrichtungen sternförmig angeordnet sind. Dadurch wird die Zugänglichkeit zu den Druckvorrichtungen verbessert. Die Werkstücke trägt ein von einer Antriebseinrichtung angetriebener Ring von einer stationären Tampondruckmaschine zur anderen. Dabei wird jede Farbe mit einem anderen Tampon auf die Werkstücke übertragen.A generic tampon device is known from DE-GM 91 03 235, in which several tampon devices are arranged in a star shape. This improves the accessibility to the printing devices. The workpieces carry a ring driven by a drive device from one stationary pad printing machine to the other. Each color is transferred to the workpieces with a different tampon.
Aus der EP 05 44 176 A1 ist bereits eine Mehrfarben-Tampondruckmaschine bekannt, bei der mehrere Tampons an einem Tamponträger um eine erste Achse drehbar angeordnet sind. Dazu sind die Klischees an einem Klischeeträger um eine zweite Achse drehbar, die parallel zur ersten angeordnet ist. Der Tamponträger und die Klischeeträger überstreichen eine gemeinsame Lageposition, in der die Tampons Farbe von den Klischees abnehmen. Die Farbe geben die Tampons nach einer 90°-Drehung auf das Druckgut ab. Das Druckgut bleibt in dieser Stellung, bis alle Farben, hier vier, übertragen sind.A multi-color tampon printing machine is already known from EP 05 44 176 A1, in which several tampons are arranged on a tampon carrier so as to be rotatable about a first axis. For this purpose, the clichés can be rotated on a cliché carrier about a second axis which is arranged parallel to the first. The tampon carrier and the cliché carrier paint over a common position in which the tampons remove color from the clichés. The tampons apply the ink to the printed matter after a 90 ° turn. The printed material remains in this position until all colors, here four, have been transferred.
Diese Vorrichtung benötigt bereits für die Übertragung von vier Farben zu viel Zeit. Zusätzlich dazu verursacht die Übertragung der einzelnen Farben durch unterschiedliche Elastizität unterschiedlicher Tampons Passungsunregelmäßigkeiten.This device already takes too much time to transmit four colors. In addition, the transfer of the individual colors causes irregularities in fit due to the different elasticity of different tampons.
Die aus der US-PS 36 88 695 bekannte Druckvorrichtung arbeitet mit thermoplastischen Farben. Dazu sind zwei Drehtische vorgesehen. Einem, auf dem die Farben erwärmt und nacheinander auf einen Träger in Form einer Membrane aufgebracht werden; und einem zweiten Drehtisch mit acht Stationen, auf dem die Farben auf den Artikel übertragen werden, indem der Rahmen, in den die Membranen eingespannt sind, um 180° zwischen einer Station am ersten Drehtisch zu einer Station am zweiten Drehtisch geschwenkt werden. Diese Anlage ist nicht für hohe Stückzahlen geeignet und auf Grund ihrer Doppeldrehtischanordnung mit größerem mechanischen Aufwand verbunden.The printing device known from US-PS 36 88 695 works with thermoplastic inks. Two rotary tables are provided for this. One on which the colors are heated and successively applied to a support in the form of a membrane; and a second eight-station turntable on which the colors are transferred to the article by pivoting the frame in which the membranes are clamped by 180 ° between a station on the first turntable and a station on the second turntable. This system is not suitable for large quantities and, due to its double turntable arrangement, involves greater mechanical effort.
Aus der US-PS 40 60 031 läßt sich eine Tampondruckvorrichtung entnehmen, die an einem Drehkreuz vier um 90° versetzte Tampons aufweist. Jeweils diametral gegenüberliegend sind entweder die Matrizen oder die Träger für die zu bedruckenden Gegenstände angeordnet. Nach jedem 90°-Takt des Drehkreuzes wird demnach ein Gegenstand bedruckt, wobei die Gegenstände nicht ständig vom gleichen, sondern von einem der vier vorhandenen Tampons bedruckt werden.From US-
Die GB-PS 804 751 betrifft eine Mehrfarbensiebdruckvorrichtung mit beispielsweise vier kreisförmig oder linear angeordneten Sieben. Sämtliche vier Farben werden nacheinander durch Verschieben der Siebe auf einen Träger aufgebracht. Dieser Träger fährt anschließend aus dem Siebbereich unter ein Tampon, das das gesamte Farbmuster aufnimmt und auf einen Gegenstand überträgt. Die Leistung der Vorrichtung ist auf Grund ihres Arbeitsablaufs sehr begrenzt.GB-PS 804 751 relates to a multi-color screen printing device with, for example, four screens arranged in a circular or linear manner. All four colors are applied one after the other by moving the screens on a carrier. This carrier then moves from the screen area under a tampon, which picks up the entire color sample and transfers it to an object. The performance of the device is very limited due to its workflow.

Erfindungsgemäß ist die Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention the object is achieved by the features of claim 1.
Durch diese Ausführungsweise wird jede einzelne Farbe während eines Mehrfarbendruckvorgangs von ein und dem selben Tampon auf das jeweilige Werkstück übertragen. Dadurch entsteht eine hohe Passergenauigkeit. Dazu kommt der Vorteil der hohen Leistungsfähigkeit dieser Vorrichtung. Nachdem für jede Farbe eine eigene Übertragungsstation vorgesehen ist, entsteht keine Wartezeit, sondern ein kontinuierlich taktmäßiger Ablauf mit hoher Frequenz.With this design, each individual color is transferred from one and the same tampon to the respective workpiece during a multicolour printing process. This creates a high register accuracy. There is also the advantage of the high performance of this device. After a separate transmission station is provided for each color, there is no waiting time, but a continuous cycle with a high frequency.
