The invention can advantageously be used for smaller print jobs with frequently changing printing ink. The number of components that come into contact with printing ink is small.
Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden im folgenden näher beschrieben. Die einzige Zeichnung zeigt die schematische Darstellung eines Querschnittes durch ein „Pumpfarbwerk" mit zwei transportablen Farbvorratsbehältern unterschiedlicher Bauart.Embodiments of the invention are shown in the drawing and are described in more detail below. The only drawing shows the schematic representation of a cross section through a "pump inking unit" with two transportable ink reservoirs of different designs.
Ein Farbwerk einer Rotationsdruckmaschine besteht u. a. aus einer Anordnung vonmehreren Walzen, von denen eine Farbauftragswalze 01 teilweise dargestellt ist. An die Farbauftragswalze 01 ist ein seitengestellfest, sowie ein verschiebbar gelagerter Farbzuführbalken 02 soweit anstellbar, daß noch ein Ringspalt 03 zwischen dem Farbzuführbalken 02 und der Mantelfläche der Farbauftragswalze 01 zum Übertragen von Druckfarbe bestehen bleibt. Zweckmäßigerweise erstrecken sich in achsparalleler Richtung der Farbauftragswalze 01 vier viertelbahnbreite, separat anstellbare Farbzuführbalken 02, denen jeweils zumindest ein Farbvorratsbehalter , zweckmäßigerweise jedoch wie in der Zeichnung dargestellt, zwei Farbvorratsbehalter, 04 oder 06 zugeordnet sind.An inking unit of a rotary printing press exists. a. from an arrangement of several rollers, of which an inking roller 01 is partially shown. On the inking roller 01 a side frame fixed, and a slidably mounted ink supply bar 02 can be adjusted so that an annular gap 03 remains between the ink supply bar 02 and the outer surface of the inking roller 01 for transferring printing ink. Expediently, four quarter-web-wide, separately adjustable ink feed bars 02 extend in the axially parallel direction of the ink application roller 01, each of which is assigned at least one ink reservoir, but expediently, as shown in the drawing, two ink reservoirs 04 or 06.
Jeder Farbvorratsbehalter 04; 06 ist auf Profilschienen 07; 08 in radialer Richtung A zur Farbauftragwalze 01 verschiebbar angeordnet, wobei die Profilschienen 07; 08 auf zwischen den Seitengesellen befindlichen Traversen 09; 11 befestigt sind.Each color reservoir 04; 06 is on rails 07; 08 slidably arranged in the radial direction A to the inking roller 01, the profile rails 07; 08 on trusses 09; 11 are attached.
Jeder der Farbvorratsbehalter 04; 06 kann alternativ zur Druckfarbenzufuhr für die Farbauftragwalze 01 benutzt werden, insbesondere dann, wenn der Farbvorrat einer Druckfarbe „fliegend" erneuert werden muß oder nachfolgend eine andere Druckfarbe vorgesehen ist.Each of the ink reservoirs 04; 06 can be used as an alternative to the ink supply for the inking roller 01, in particular when the ink supply of a printing ink has to be renewed "on the fly" or another printing ink is subsequently provided.
Nach einem ersten Ausführungsbeispiel weist der Farbvorratsbehalter 04 einen mit Druckfarbe 10 befüllbaren und mit einer Auslaßöffnung 12 versehenen Farbvorratsraum 13 auf, welcher, durch einen in einer Ebene 15 hin- und herbewegbaren Farbschieber 14 getrennt, an einen Druckraum 16 grenzt- Beide Räume 13; 16 haben einen gleichen Querschnitt, an dessen Konturen der Farbschieber 14 saugend anliegt. Am Ende des Druckraumes 16 ist eine Zuleitung 17 für Druckmittel, z. B. Druckluft vorgesehen, welche zu einer farbbalkennahen Schnellkupplung 18 führt, deren erstes Teil 19 mit dem Farbvorratsbehalter 04 und deren zweites Teil 21 mit dem Farbzuführbalken 02 verbunden ist.According to a first exemplary embodiment, the ink supply container 04 has an ink supply space 13 which can be filled with printing ink 10 and provided with an outlet opening 12 and which, separated by a color slide 14 which can be moved back and forth in a plane 15, borders on a printing space 16. Both spaces 13; 16 have the same cross-section, on the contours of which the color slide 14 rests. At the end of the pressure chamber 16 is a supply line 17 for pressure medium, for. B. Compressed air is provided, which leads to a quick coupling 18 near the color bar, the first part 19 of which Ink reservoir 04 and the second part 21 is connected to the ink supply bar 02.
Die Auslaßöffnung 12 mündet ebenfalls in eine farbbalkennahe Schnellkupplung 22, die gleichfalls wie die Schnellkupplung 18 aufgebaut ist. Das im Farbzuführbalken 02 befindliche zweite Teil 21 der Schnellkupplung 18 ist über eine Leitung 23 mit einem Wegeventil 20 verbunden, welche wiederum mit einer zentralen Druckversorgung 24, z. B. für Druckluft, in Verbindung steht. Das zweite Teil der Schnellkupplung 22 ist über ein Rückschlagventil 25 sowie über eine obere Zuleitung 26 für eine in achsparalleler Richtung verlaufende Verteilerleitung 27 zum Querfördern der Druckfarbe 10 verbunden. Die Verteilerleitung 27 führt zu einer Anzahl von drei bis zehn, vorzugsweise fünf Austrittsleitungen 28 je %-breitem Farbzuführbalken 02. Die Austrittsleitungen 28 enden jeweils in einer zum Ringspalt 03 gerichteten Austrittsöffnung 29.The outlet opening 12 also opens into a quick coupling 22 near the color bar, which is also constructed like the quick coupling 18. The second part 21 of the quick coupling 18 located in the ink supply bar 02 is connected via a line 23 to a directional valve 20, which in turn is connected to a central pressure supply 24, e.g. B. for compressed air. The second part of the quick coupling 22 is connected via a check valve 25 and via an upper feed line 26 for a distributor line 27 running in the axis-parallel direction for the cross-conveying of the printing ink 10. The distributor line 27 leads to a number of three to ten, preferably five, outlet lines 28 per%-wide ink supply bar 02. The outlet lines 28 each end in an outlet opening 29 directed towards the annular gap 03.
Der Farbzuführbalken 02 weist einen alternativen Anschluß für den zweiten Farbvorratsbehalter 06 auf. Dafür sind zweite, farbbalkenfeste Teile 34 einer unteren Schnellkupplung 37 über eine untere, erste Anschlußleitung 38 über das Wegeventil 20 mit der zentralen Druckversorgung 24 verbunden. Zweite farbkastenfeste Teile 34 einer oberen Schnellkupplung 36 sind über eine Zuleitung 41 mit der in achsparalleler Richtung der Farbauftragwalze 01 verlaufenden Verteilerleitung 27 zum Querfördern der Druckfarbe 10 verbunden. Diese Verteilerleitung 27 führt wiederum zu fünf unteren Austrittsleitungen 28 des %-bahnbreiten Farbzuführbalkens 02.The ink supply bar 02 has an alternative connection for the second ink reservoir 06. For this purpose, second, color bar-fixed parts 34 of a lower quick coupling 37 are connected to the central pressure supply 24 via a lower, first connecting line 38 via the directional control valve 20. Second ink box-fixed parts 34 of an upper quick coupling 36 are connected via a feed line 41 to the distributor line 27, which runs in the axis-parallel direction of the inking roller 01, for the transverse conveying of the printing ink 10. This distributor line 27 in turn leads to five lower outlet lines 28 of the% web-wide ink feed bar 02.
Nach einem zweiten Ausführungsbeispiel weist der untere Farbvorratsbehalter 06 einen in einem Druckraum 44 befindlichen und mit Druckfarbe 10 befüllbaren Farbsack 46 auf. Der Farbsack 46 ist mittels Druckmittel 24, z. B. Druckluft zusammenpreßbar angeordnet und weist eine nach einer farbbalkennahen ersten Stirnseite des Farbvorratsbehälters 06 gerichtete Auslaßöffnung 47 für die Druckfarbe 10 auf. Die Auslaßöffnung 47 ist mit einem ersten Teil 48 der unteren Schnellkupplung 36 verbunden. In der Nähe der zweiten Stirnseite des Farbvorratsbehälters 06, also gegenüber der Auslaßöffnung 47 ist eine vorratsbehälterfeste Verbindungsleitung 49 vorgesehen, die den Druckraum 44 mit einem ersten Teil 48 der unteren Schnellkupplung 37 zum Einleiten von Druckluft verbindet.According to a second exemplary embodiment, the lower ink reservoir 06 has an ink bag 46 which is located in a printing space 44 and can be filled with printing ink 10. The ink bag 46 is by means of pressure medium 24, for. B. compressed air is arranged compressible and has an outlet opening 47 for the printing ink 10 directed towards a first end of the ink reservoir 06 near the ink bar. The outlet opening 47 is connected to a first part 48 of the lower quick coupling 36. In the vicinity of the second end face of the ink reservoir 06, that is to say opposite the outlet opening 47, a connection line 49 fixed to the reservoir is provided, which connects the pressure chamber 44 to a first part 48 of the lower quick coupling 37 for introducing compressed air.
Die Funktion des ersten Farbvorratsbehälters 04 ist wie folgt: Der z. B. durch die Auslaßöffnung 12 mit Druckfarbe befüllte obere Farbvorratsbehalter 04 wird mittels des Handgriffes 51 auf den Profilschienen 07 in Radialrichtung A bewegt, bis die Schnellkupplungen 18; 22 miteinander in Verbindung sind. Durch Zuführen von Druckluft in den Druckraum 16 wird der Farbschieber 14 in Richtung Farbzuführbalken 02 gedrückt, so daß die Druckfarbe 10 über die Auslaßöffnung 12 sowie über die Leitungen 26 bis 28 und die entsprechende Austrittsöffnung 29 in den Ringspalt 03 austritt.The function of the first ink reservoir 04 is as follows: The z. B. through the outlet opening 12 filled with ink upper ink reservoir 04 is moved by means of the handle 51 on the rails 07 in the radial direction A until the quick couplings 18; 22 are connected. By supplying compressed air to the pressure chamber 16, the ink slide 14 is pressed in the direction of the ink supply bar 02, so that the printing ink 10 exits into the annular gap 03 via the outlet opening 12 and via the lines 26 to 28 and the corresponding outlet opening 29.
Eine Füllstandsanzeige für Druckfarbe kann z. B. dadurch geschaffen werden, daß ein Schieberteil 52 aus elektrisch leitfähigem Material besteht und beim Entleeren des Farbvorratsraumes 13 mit ersten oder zweiten Näherungsschaltern 53; 54 in Berührung kommt, was ein entsprechendes Signal auslöst.A level indicator for printing ink can e.g. B. be created in that a slide member 52 consists of electrically conductive material and when emptying the ink reservoir 13 with first or second proximity switches 53; 54 comes into contact, which triggers a corresponding signal.
Der zweite Farbvorratsbehalter 06 kann in Betrieb genommen werden, indem der Druckraum 44 über die Verbindungsleitung 49 mit Druckluft beaufschlagt wird. Die Druckluftzufuhr zum oberen Farbvorratsbehalter 04 ist dann durch das Umschalten des Wegeventils 20 unterbrochen.The second ink reservoir 06 can be put into operation by applying compressed air to the pressure chamber 44 via the connecting line 49. The compressed air supply to the upper ink reservoir 04 is then interrupted by the switching of the directional valve 20.
Es ist jeweils nur einer der Farbvorratsbehalter 04 oder 06 in Betrieb.Only one of the ink reservoirs 04 or 06 is in operation at a time.
Mittels der druckbeaufschlagten Druckfarbe selbst, wird also wechselweise die erste Zuleitung 26 und die zweite Zuleitung 41 geöffnet bzw. geschlossen.By means of the pressurized printing ink itself, the first feed line 26 and the second feed line 41 are alternately opened or closed.
Die Farbvorratsbehalter 04 oder 06 können jeweils mit Farbschieber 14 oder mit Farbsack 46 ausgebildet sein und mit Druckluft betrieben werden. Es ist auch möglich, das Druckmittel 24 nicht nur gasförmig, sondern auch flüssig auszubilden, d. h. Wasser oder Öl zu verwenden.The ink supply containers 04 or 06 can each be designed with a paint slide 14 or with an ink bag 46 and can be operated with compressed air. It is also possible to design the pressure medium 24 not only in gaseous form but also in liquid form, ie to use water or oil.
Das Druckmittel wirkt immer indirekt auf die Druckfarbe 10, d. h. unter Zwischenschaltung des Schiebers 14 bzw. des Farbsackes 46.The pressure medium always acts indirectly on the printing ink 10, i. H. with the interposition of the slide 14 or the paint bag 46.
Die Druckfarbe 10 wird ohne Zwischenschaltung einer Pumpe zur Austrittsöffnung 29 befördert. The printing ink 10 is conveyed to the outlet opening 29 without the interposition of a pump.
