Description

Einfärbevorrichtung an Kopfdruckpressen Zur Bewegung der Farbauftragwalzen an Kopfdruckpressen waren bisher Antriebsgestänge üblich, die, abgesehen davon, daß sie viel Raum beanspruchten und dadurch bei der Maschine leicht störend wirkten, teuer waren und wegen der vorhandenen, der Abnutzung unterworfenen Gelenke auf die Dauer ein zuverlässiges Arbeiten in Frage stellten.Inking device on head presses For moving the inking rollers up to now, drive rods have been common on head presses, which apart from that they took up a lot of space and were therefore slightly disruptive to the machine, were expensive and because of the existing joints subject to wear and tear on the Questioned reliable work over the long term.

Die Erfindung hilft diesen Übelständen dadurch ab, daß das Antriebsgestänge der Farbauftragwalzen auf einen einzigen, die Walzen tragenden Hebel beschränkt wird, der seine Bewegung vom auf und ab gehenden Druckkopf unmittelbar erhält.The invention helps these deficiencies in that the drive linkage the inking rollers are limited to a single lever that carries the rollers which receives its movement immediately from the printhead going up and down.

In den Abb. i und 2 der Zeichnung ist ein. Ausführungsbeispiel des Gegenstandes der Erfindung in zwei Arbeitsstellungen schematisch veranschaulicht.In Figs. I and 2 of the drawing is a. Embodiment of the Subject of the invention illustrated schematically in two working positions.

In dem den Druckstock i tragenden Druckkopf 2 ist -um den Drehzapfen 2a ein. Schwenkhebel 3 drehbar gelagert. Dieser ist mit einem Schlitz 3- versehen, in den eine Rolle oder ein Kulissenstein q. eingreift, der an dem Maschinengestell 5 drehbar gelagert ist. Wird nun auf bekannte Weise der Druckkopf 2 - im vorliegenden Falle durch eine Zugstange 6 und eine Kurbel 7 - auf und ab bewegt, so erfolgt eine Schwenkbewegung des Hebels 3. Beim Senken des Druckkopfes 2 wird der Hebel 3 nach dem Farbwerk 8 bewegt und bringt die Farbauftragwalze 9 in Farbaufnahmestellung, während beim Heben des Druckkopfes 2 der Hebel 3 die Auftragwalze 9 über den Druckstock r bewegt, der dadurch eingefärbt wird.In the printing head 2 carrying the printing block i there is a pivot 2a around the pivot pin. Swivel lever 3 rotatably mounted. This is provided with a slot 3- , in which a role or a sliding block q. engages, which is rotatably mounted on the machine frame 5. If the print head 2 is now moved up and down in a known manner - in the present case by means of a pull rod 6 and a crank 7 - a pivoting movement of the lever 3 takes place the inking roller 9 in the ink pick-up position, while when the printhead 2 is raised, the lever 3 moves the applicator roller 9 over the printing block r, which is thereby colored.

Durch entsprechende Krümmung des Schlitzes 3a kann die Bewegung der Auftragwalze 9 beschleunigt oder verzögert werden. Dadurch wird es möglich, die Dauer der Farbaufnahme am Farbwerk 8 sowie die Dauer der Farbabgabe am Druckstock i wahlweise zu bestimmen.The movement of the applicator roller 9 can be accelerated or decelerated by a corresponding curvature of the slot 3a. This makes it possible to selectively determine the duration of the ink uptake on the inking unit 8 and the duration of the ink release on the printing block i.
