Description
Die Erfindung betrifft Tiegeldruckpressen mit mehreren vom Druckkopf unabhängigen, mittels einer dauernd umlaufenden Kette um diesen herumgeführten Farbauftragwalzen, und sie bezweckt, den Druckkopf durch möglichst einfache Weise so zu steuern, daß er im oberen Totpunkt seiner Bewegung während eines Teiles der Drehung der Hauptantriebswelle nahezu stillsteht, damit den Farbwalzen die zum Einfärben der Form benötigte Zeit gelassen wird.The invention relates to platen printing presses with several independent from the print head, by means of a continuously revolving chain around these inking rollers, and its purpose is to control the print head in the simplest possible way so that it at the top dead center of its movement during part of the rotation of the main drive shaft almost stationary so that the inking rollers are given the time it takes to color the form.
Die Erfindung besteht darin, daß der Druckkopfantrieb aus zwei Lenkstangen besteht, deren eine Enden mit einem Exzenter bzw. einer mit diesem kämmenden Kurbelscheibe und deren andere Enden mit einer an den Zapfen des Druckkopfes schwingbaren, ein Gleitstück tragenden Ouerstange gelenkig verbunden sind.The invention consists in that the print head drive consists of two steering rods, one ends of which with an eccentric or a crank disk meshing with this and the other ends thereof with an Ouerstange which is swingable on the pin of the print head and carries a slide are articulated.
ao In der schematischen Darstellung nach Abb. ι bezeichnen fa und ga die zwei Scheiben, die ihre Bewegung von der Hauptantriebswelle erhalten und die mit einer Kurbelscheibe F bzw. einem Exzenter G ver-ao In the schematic representation according to Fig. ι denote a f and g a the two discs, which receive their motion from the main drive shaft and the comparison with a crank or an eccentric F G
*5 bunden sind, an deren Zapfen zwei Lenkstangen D und E angebracht sind.* 5 are tied with two steering rods D and E attached to their journals.
Beide Scheiben sind derart zueinander ge^ stellt, daß ihre Zapfen um 900 verstellt sind, wenn die Scheibe F sich in ihrer Mittelstellung befindet. Die Enden der Stangen D und E sind an den Enden einer Querstange H angelenkt, die in ihrer Mitte um einen Zapfen / des zu bewegenden Teiles schwingbar gelagert und an dem Gleitstück Ea fest angebracht ist, das in den Gleitschienen Ga gleitet, und mit dem zu bewegenden Druckkopf verbunden ist.Both discs are in such relative ge ^ represents that their pins are adjusted to 90 0, F when the disk is in its center position. The ends of the rods D and E are hinged to the ends of a transverse rod H , which is pivotably mounted in its center around a pin / of the part to be moved and is fixedly attached to the slide E a , which slides in the slide rails G a , and with is connected to the print head to be moved.
Das Gleitstück bewegt sich während der Arbeit nach Form einer Kurve, deren Gestalt von den Abmessungen der verschiedenen Teile oder Glieder des Druckkopfantriebes, besonders von dem Verhältnis zwischen den Radien beider Kurbeln abhängt. So zeigt Abb. 2 die Gestalt der Kurve X, die in der Umgebung des Totpunktes einen nahezu geradlinigen Teil aufweist, der die Verlangsamung oder den fast völligen Stillstand der Bewegung des Gleitstückes bzw. des Druckkopfes andeutet.The slide moves during the work in the form of a curve, the shape of which depends on the dimensions of the various parts or links of the print head drive, especially on the ratio between the radii of the two cranks. Thus Fig. 2 shows the shape of the curve X, which has an almost straight part in the vicinity of the dead center, which indicates the slowing down or the almost complete standstill of the movement of the slide or the print head.
Die Verlangsamung des Gleitstückes ist gemäß beiliegender Zeichnung derart, daß während 28 "/0 der Umlauf zeit der Hauptantriebswelle in der Zeit während des Einfärbens der Form der Hub des Gleitstückes kaum '/eo seines vollen Hubes beträgt.The slowing down of the slider is according to the accompanying drawing such that during 28 "/ 0 of the revolution time of the main drive shaft in the time during the coloring of the shape, the stroke of the slider is hardly ½ of its full stroke.
