PumpfarbwerkPump inking unit
Die Erfindung betrifft ein Pumpfarbwerk gemäß dem Oberbegriff des Anspruches 1.The invention relates to a pump inking unit according to the preamble of claim 1.
Durch die DE 91 00 535 IM ist eine Pumpeinrichtung zum Zuführen fließfähiger Substanzen zu einer Druck- oder Beschichtungsmaschine bekannt, wobei eine einstückige lösbare Geräteeinheit zumindest aus einer Pumpe, einem Pumpenantrieb und einem Vorratsbehälter besteht.A pump device for supplying flowable substances to a printing or coating machine is known from DE 91 00 535 IM, a one-piece detachable device unit consisting at least of a pump, a pump drive and a storage container.
Die DE 38 32 183 C1 offenbart eine Pumpeinrichtung mit einem auswechselbaren Farbbehälter und einer Pumpe. Ein Antrieb der Pumpe und die Pumpe können mittels einer Elektromagnetkupplung gekoppelt werden.DE 38 32 183 C1 discloses a pump device with an exchangeable paint container and a pump. A drive of the pump and the pump can be coupled by means of an electromagnetic clutch.
Der Erfindung liegt die Aufgabe zugrunde, eine Farbpumpe für ein Pumpfarbwerk einer Rotationsdruckmaschine zu schaffen.The invention has for its object to provide an ink pump for a pump inking unit of a rotary printing press.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The object is achieved by the features of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß dem auswechselbaren Farbbehälter des Pumpfarbwerkes nur die unbedingt für den Farbaustrag benötigten Bauteile zugeordnet sind. Aus diesem Grunde ist zumindest der Antrieb für die Farbpumpe in der seitengestellfest gelagerten Traverse angeordnet. Die Kupplung zwischen dem in der Traverse befindlichen Antrieb und der im Farbbehälter befindlichen Farbpumpe ist robust ausgeführt, so daß Verunreinigungen durch Farbe und dergleichen die Kraftübertragung des Pumpenantriebes nicht beeinträchtigen können. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die einzige Zeichnung zeigt die schematische Darstellung des Querschnitts durch ein Pumpfarbwerk mit einer auf einer seitengestellfesten Traverse angeordneten teilpapierbahnbreiten transportablen FarbabgabeeinheitThe advantages that can be achieved with the invention are, in particular, that only the components absolutely necessary for the color discharge are assigned to the replaceable ink container of the pump inking unit. For this reason, at least the drive for the paint pump is arranged in the crossbar which is fixed to the side frame. The coupling between the drive located in the crossbeam and the paint pump located in the paint container is robust, so that contamination from paint and the like cannot impair the power transmission of the pump drive. An embodiment of the invention is shown in the drawing and will be described in more detail below. The only drawing shows the schematic representation of the cross-section through a pump inking unit with a transport unit for ink dispensers that is transportable on a cross member fixed to the side frame
Ein Pumpfarbwerk 01 besteht aus einem oder mehreren, vorzugsweise aus vier in achsparalleler Richtung zu einer druckmaschinenbreiten Farbauftragswalze 02 nebeneinander angeordneten transportablen Farbabgabeeinheiten 03. Die Farbabgabeeinheiten 03 sind auf einer zwischen den Seitengestellen in achsparalleler Richtung verlaufenden Traverse 04 und in radialer Richtung der Farbauftragwalze 02 verschiebbar angeordnet. Dabei sind die Farbabgabeeinheiten 03 jeweils auf Profilschienen 06 angeordnet, die auf der Traverse 04 quer zu deren Längsachse verlaufen. Die traversenfesten Profilschienen 06 haben am farbauftragwalzenseitigen Ende einen Anschlag 07 zur Begrenzung des Einschiebevorganges der Farbabgabeeinheit 03 sowie nicht dargestellte Mittel zum Arretieren der eingeschobenen Farbabgabeeinheit 03.A pump inking unit 01 consists of one or more, preferably four, portable ink dispensing units 03 arranged next to one another in the axis-parallel direction to a printing machine-wide inking roller 02. The ink dispensing units 03 are arranged so as to be displaceable on a crossbar 04 running between the side frames in the axis-parallel direction and in the radial direction of the inking roller 02 , The ink delivery units 03 are each arranged on profile rails 06, which run on the cross member 04 transversely to its longitudinal axis. The crossbar-fixed profile rails 06 have a stop 07 at the end of the inking roller on the inking roller to limit the insertion process of the ink delivery unit 03 and means (not shown) for locking the inserted ink delivery unit 03.
Jede auswechselbare oder transportable Farbabgabeeinheit 03 weist einen durch eine Öffnung 08 befüllbaren sowie mittels eines Deckels 09 verschließbaren Farbvorratsraum 11 auf.Each exchangeable or transportable ink delivery unit 03 has an ink supply space 11 which can be filled through an opening 08 and closed by means of a cover 09.
Der Farbvorratsraum 11 ist über eine Abflußleitung 12 sowie ein Rückschlagventil 13 mit dem Eingang einer in der Farbabgabeeinheit 03 befindlichen Farbpumpe, z. B. Membranpumpe 14, verbunden. Der Ausgang der Membranpumpe 14 ist wiederum über ein Rückschlagventil 16 und eine Zuführleitung 17 mit einer Verteilerleitung 18 verbunden. The ink reservoir 11 is via a drain line 12 and a check valve 13 with the input of an ink pump located in the ink delivery unit 03, for. B. diaphragm pump 14 connected. The outlet of the diaphragm pump 14 is in turn connected to a distributor line 18 via a check valve 16 and a feed line 17.
Die Verteilerleitung 18 verläuft abweichend von der in der Zeichnung dargestellten Lage achsparallel zur Farbauftragswalze 02 und weist eine Anzahl von drei bis zehn, vorzugsweise fünf, jeweils voneinander beabstandete Austrittsleitungen 19 für je eine viertelbreite Farbabgabeeinheit 03 auf. Die Austrittsleitungen 19 verlaufen jeweils parallel zueinander in radialer Richtung und münden jeweils über eine Austrittsöffnung 21 in einem kreisbogenförmigen Ringspalt 22, welchen die Farbauftragswalze 02 mit ihrer Mantelfläche durchläuft.Deviating from the position shown in the drawing, the distributor line 18 runs axially parallel to the inking roller 02 and has a number of three to ten, preferably five, respectively spaced-apart outlet lines 19 for a quarter-wide ink dispensing unit 03. The outlet lines 19 each run parallel to one another in the radial direction and each open via an outlet opening 21 in an arcuate annular gap 22, through which the ink application roller 02 passes with its outer surface.
Ein Pumpenantrieb 23 ist in der Traverse 04 angeordnet und besteht z. B. aus einem pneumatisch betätigbaren Arbeitszylinder 24, welcher über einen Zuführstutzen 26 intervallmäßig mit Druckluft versorgt wird. Die im Arbeitszylinder 24 befindliche Kolbenstange 27 ist an ihrem zylinderabgewandten Ende mit einem ersten Teil, z. B. einem Dauermagneten 28 einer zweiteiligen Kupplung 29 versehen, welcher in einer vertikal verlaufenden Führung, z. B. Bohrung 31 der Traverse 04 im Betriebszustand hin- und herbewegbar ist, d. h. eine oszillierende Bewegung ausführt. Die Bohrung 31 liegt einer in der auswechselbaren Farbabgabeeinheit 03 befindlichen Führung oder Bohrung 32 direkt gegenüber, so daß beide Bohrungen 31; 32 miteinander fluchten.A pump drive 23 is arranged in the cross member 04 and consists, for. B. from a pneumatically actuated working cylinder 24, which is supplied with compressed air intermittently via a feed connector 26. The piston rod 27 located in the working cylinder 24 is provided with a first part, e.g. B. provided a permanent magnet 28 of a two-part clutch 29, which in a vertical guide, for. B. bore 31 of the cross member 04 can be moved back and forth in the operating state, d. H. makes an oscillating movement. The bore 31 lies directly opposite a guide or bore 32 located in the exchangeable ink delivery unit 03, so that both bores 31; 32 are aligned.
In der Bohrung 32 ist ein zum Dauermagneten 28 gegensätzlich polarisierter, zweiter Dauermagnet 33 angeordnet, welcher mit der membranabgewandten Seite der Kolbenstange 34 der Membranpumpe 14 fest verbunden ist.Arranged in the bore 32 is a second permanent magnet 33 which is polarized opposite to the permanent magnet 28 and which is firmly connected to the side of the piston rod 34 of the diaphragm pump 14 facing away from the diaphragm.
Es ist natürlich auch möglich, als Pumpenantrieb 23 einen doppelt wirkenden Arbeitszylinder, ein Kurbelgetriebe oder ein sogenanntes Gleitsteingetriebe zu verwenden. It is of course also possible to use a double-acting working cylinder, a crank gear or a so-called sliding block gear as the pump drive 23.
Das Pumpfarbwerk 01 arbeitet wie folgt:Pump inking unit 01 works as follows:
Nachdem der Farbvorratsraum 11 mit Druckfarbe gefüllt ist, wird die Farbabgabeeinheit 03 z. B. mittels Handgriffen 36 auf die Profilschienen 06 gesetzt, gegen den Anschlag 07 geschoben und arretiert. Durch Betätigung des Pumpenantriebes 23 werden die Dauermagnete 28; 33 kraftschlüssig miteinander verbunden und die Druckfarbe wird von der Membranpumpe 14 in die Verteilerleitung 18 und somit in die Austrittsleitungen 19 und über die Austrittsöffnungen 21 zum Ringspalt 22 und weiter zur Mantelfläche der Farbauftragswalze 02 gebracht.After the ink supply space 11 is filled with printing ink, the ink delivery unit 03 is z. B. by means of handles 36 on the rails 06, pushed against the stop 07 and locked. By actuating the pump drive 23, the permanent magnets 28; 33 non-positively connected to one another and the printing ink is brought from the diaphragm pump 14 into the distributor line 18 and thus into the outlet lines 19 and via the outlet openings 21 to the annular gap 22 and further to the outer surface of the inking roller 02.
Es kann auch für jede Austrittsöffnung 21 ein Dosierventil vorgesehen werden. A metering valve can also be provided for each outlet opening 21.
