Description
Elektrisch betriebene Vorrichtung zum selbsttätigen Abstellen der Bogenzuführvorrichtung oder des Druckzylinders einer Druckmaschine beim Ausbleiben der Bogen Bei Störungen in der Bogenzufuhr bei Anlegevorrichtungen für Druckmaschinen wird das Abstellen. der Bogenzuführvorr ichtung oder des Druckzylinders allgemein durch elektrische Kontakte auf dem Anlegetisch bewirkt, die mit Schleiffedern über dem laufenden Bogen zusammenarbeiten. Liegen- die Kontakte an den äußeren Rändern der Bogen, so entstehen leicht Störungen durch ,unnützes Ausschalten; liegen ,die Kontalkte, wie es wünschenswert ist, in der Bogenmitte, so entstehen Störungen durch Verschmutzen der Kontakte.Electrically operated device for automatically turning off the Sheet feeder or the impression cylinder of a printing press when it fails the sheet In the event of malfunctions in the sheet feed with feed devices for printing machines is turning off. the sheet feeder or the impression cylinder in general caused by electrical contacts on the feed table, which are covered with slide springs work together on the running arc. Are the contacts on the outer edges the arc, disturbances easily arise through useless switching off; lie that Contals, as is desirable, in the middle of the bow, this creates disturbances Contamination of the contacts.
Dieser letzte Übelstand tritt besonders stark bei vollfarbigen. Arbeiten, !in Erscheinung; durch häufiges Reinigen der Kontakte geht viel Zeit verloren. Besonders beim Mehrfarbendruck gehen bei Störungen in der Papierzufuhr beim Drucken der letzten Farben durch Nichtabstellen der Druckzylinder viel wertvolle fertige Druckbogen verloren, ganz abgesehen von der Zeit, die das Waschen der beschmutzten Zylinder erforert. Der Verlust an Bogen und Zeit kann durch diese Störungen bei besonders ungünstigen Arbeiten sehr groß sein.This last drawback is particularly pronounced with full-color. Work, ! in appearance; Frequent cleaning of the contacts wastes a lot of time. Particularly in multi-color printing, if there are faults in the paper feed when printing, the last one Colors by not turning off the printing cylinder a lot of valuable finished printed sheets lost, not to mention the time it takes to wash the stained cylinders explored. The loss of arc and time can be particularly severe as a result of these disorders unfavorable work can be very large.
Erfindungsgemäß wird nun, - wie in den Abb, x und 2 der Zeichnung dargestellt ist, der Kontälzt a über der Bahn des Bogens b angeordnet; dann kann kein Verschmutzen der Schleiffeder c mehr Schaden anrichten. Tritt eine Störung in der Bogenzufuhr ein, schließt sich der Kontakt a durch Senken der Schleiffeder in eine Vertiefung d des, Anlegetisches e.According to the invention is now, - as in Figs, x and 2 of the drawing is shown, the Kontälzt a arranged over the path of the sheet b; then can no more dirtying of the slide spring c cause damage. A malfunction occurs in the sheet feed, the contact a closes by lowering the slide spring into a recess d of the feed table e.
Bei :geregeltem Lauf der Bogen b wird die leichte Schleiffeder von den Bogen gehoben; somit ist der Kontakt a geöffnet.With: a regulated run of the sheet b, the light sanding spring of raised the bow; thus the contact a is open.
Diese Anordnung gewährleistet ein, ;sicheres Arbeiten, kann mit geringen Mitteln an jeder schon vorhandenen elektrischen Anlage angebaut werden und -spart somit Zeit und wertvolle Druckbogen.This arrangement guarantees; safe working can with limited resources at each existing electrical system are cultivated and - thus saving time and valuable printed sheets.
