Definitions
- the invention relates to an ink fountain for printing machines according to the preamble of the first claim.
- the ink fountain side parts are first set against the ink fountain roller and there is rough regulation of the ink metering device, e.g. B. the color meter or the color metering elements with the machine stopped.
- the inking unit see DE patent application Az. F 10648, At .: 23.06.51
- the ink fountain see DE utility model 1 675 338
- parts of the ink fountain (DE- OS 3 325 005) or the color metering device (DE utility model 1 891 449)
- a predetermined operating temperature possibly also cooled, in order to keep the temperature gradient in the individual components small overall.
- thermal expansions against one another are also brought to a limited extent, so that the thermal stresses in the ink fountain, the dosing means and the ink fountain roller partially cancel each other out. Reduced tension due to thermal expansion leads to fewer ink fluctuations on the ink fountain roller, which can be more easily adjusted by the printer.
- the thermal insulation on the bottom and back of the ink fountain reduces the annoying heating of these parts, which are particularly exposed to the hot air flow from the sheet guiding devices of the machine.
- the side of the ink fountain facing the ink fountain roller is only slightly affected by the warm machine air, depending on the installation conditions. This part of the ink fountain is then at a lower temperature than the rest of the ink fountain body. To equalize the temperature, the hot air flow is directed by fans and baffles at the ink fountain edge on the metering side. This reduces the temperature gradient to less than 1 degree. Due to this low temperature gradient, correspondingly lower tensions occur in the ink fountain lower part, the metering elements and the ink fountain roller, i.e. H. the set color gap is subject to fewer fluctuations in the thickness, which can be more easily adjusted by the printer without the need for temperature control or additional heating.
- the invention also brings about a temperature control of the printing ink and a stabilization of the ink / fountain solution emulsion. Since the air from the sheet guiding systems of the machine heats up after a short period of operation, the ink is heated by blowing on the ink fountain roller. Because of this temperature control, the printing ink shows a much more uniform viscosity behavior in the warm-up phase of the machine, which is also important for constant Color guide is.
- the ink fountain 2 shown in FIGS. 1 and 2 is deposited on both sides on supports which are connected by a cross member 5 and can be inserted into the machine as a whole via rails of the machine frame (not shown here). This operating position is defined by stops, not shown, which end the insertion movement.
- the ink fountain 2 is arranged such that it can be pivoted away from the ink fountain roller 1 via a pivot point, not shown.
- the ink fountain 2 is delimited on the two end faces in a known manner by in each case one ink fountain side part, the end face of which is provided with a recess corresponding to the surface curvature of the ink fountain roller 1. This will cause the color to leak in the Contacting area prevented.
- the pivoting movement of the ink fountain 2 to the ink fountain roller 1 takes place via a toggle lever (not shown) and a swivel gear, also in a known manner.
- the underside of the ink fountain fuselage is provided with thermal insulation 6.
- a middle region (1/2) of the side of the ink fountain body facing the ink fountain roller 1 is acted upon by a warm air flow during the operating time of the printing press, which is increased by fans 3.
- the fans 3 are in the vicinity of a heat source arising in the operating time in the printing press, e.g. B. arranged below the ink fountain 2 above a sheet guide drum, so that the hot air flow from this drum acts on this area of the ink fountain 2.
- the fans 3 are surrounded by a guide device 4 such that the hot air is said middle area comes exactly into the gap between the ink fountain roller 1 and the side of the ink fountain body facing this. In this way, all essential parts of the ink fountain 2 are washed around evenly.
- insulation material against the flow of warm air for example as thermal insulation 6 three mm thick styrofoam with aluminum lamination is suitable.
- FIGS. 1 and 2 The air flow is illustrated by arrows in FIGS. 1 and 2, while in FIG. 1 it is also indicated that the guiding device 4 encloses the traverse 5 and thereby leaves a gap to the ink fountain body between the guiding device and the traverse, the guiding device 4 being by means of a screw is attached to the traverse.

Abstract
Description
Die Erfindung betrifft einen Farbkasten für Druckmaschinen nach dem Oberbegriff des 1. Patentanpruches.The invention relates to an ink fountain for printing machines according to the preamble of the first claim.
Farbkästen der genannten Gattung sind weit verbreitet und allgemein bekannt.Color boxes of the type mentioned are widespread and generally known.
Beim Offsetdruck hängt eine störungsfreie Druckproduktion im hohen Maße von der Gleichmäßigkeit der Farbdosierung ab. Üblicherweise werden zum Einstellen des Farbwerkes nach dem Einfüllen der Farbe zunächst die Farbkastenseitenteile an die Farbkastenwalze federnd angestellt und es wird eine grobe Regulierung der Farbdosiereinrichtung, z. B. des Farbmessers oder der Farbdosierelemente bei stillstehender Maschine vorgenommen.In offset printing, trouble-free print production depends to a large extent on the uniformity of the ink dosage. Usually, to adjust the inking unit after filling the ink, the ink fountain side parts are first set against the ink fountain roller and there is rough regulation of the ink metering device, e.g. B. the color meter or the color metering elements with the machine stopped.
Aus der Praxis ist es bekannt, daß die Farbführung des Farbwerkes stark von Temperatureinflüssen abhängig ist. Unerwünschte örtliche Erwärmungen des Farbkastens, der Dosierelemente und der Farbkastenwalze führen über Verspannungen zu Farbschwankungen auf der Farbkastenwalze, die vom Drucker nur schwer auszuregeln sind. Diese Farbschwankungen treten vor allem nach kurzen Betriebsunterbrechungen der Maschine auf, z. B. bei Waschintervallen, Stoppern oder nach Produktionspausen.It is known from practice that the color control of the inking unit is strongly dependent on temperature influences. Undesirable local heating of the ink fountain, the dosing elements and the ink fountain roller leads to tension fluctuations in the ink fountain roller fluctuations, which are difficult for the printer to correct. These color fluctuations occur especially after brief machine interruptions, e.g. B. at wash intervals, stoppers or after production breaks.
Zur Lösung der mit Temperaturschwankungen verbundenen Probleme ist es bereits bekannt, das Farbwerk (siehe DE-Patentanmeldung Az. F 10648, At.: 23.06.51), den Farbkasten (siehe DE-Gebrauchsmuster 1 675 338), Teile des Farbkastens (DE-OS 3 325 005) oder die Farbdosiereinrichtung (DE-Gebrauchsmuster 1 891 449) bei Maschinenstillstand oder bei laufender Maschine geregelt oder ungeregelt auf eine vorbestimmte Betriebstemperatur zu Erwärmen, gegebenenfalls auch abzukühlen, um insgesamt das Temperaturgefälle in den einzelnen Bauteilen klein zu halten. Durch eine derartige Erwärmung werden je nach Angriffspunkt der Wärme begrenzt auch Wärmedehnungen gegeneinander zur Wirkung gebracht, so daß sich die thermischen Verspannungen im Farbkasten, den Dosiermitteln und der Farbkastenwalze teilweise gegenseitig aufheben. Verringerte Verspannungen durch Wärmedehnungen führen zu geringeren Farbschwankungen auf der Farbkastenwalze, die vom Drucker leichter ausgeregelt werden können.To solve the problems associated with temperature fluctuations, it is already known to use the inking unit (see DE patent application Az. F 10648, At .: 23.06.51), the ink fountain (see
Bei den bekannten Maßnahmen ist jedoch von Nachteil, daß stets eine zusätzliche, in der Temperatur regelbare Wärmequelle installiert werden muß, was nicht nur zusätzlichen Aufwand bedeutet, sondern unter Umständen an dem erforderlichen Angriffspunkt nur schwer möglich ist.In the known measures, however, it is disadvantageous that an additional heat source that can be regulated in temperature must always be installed, which not only means additional effort, but may also be difficult at the required point of attack.
Es ist Aufgabe der Erfindung, örtliche Wärmedehnungsunterschiede im Farbkasten, den Dosiermitteln und in der Farbkastenwalze zu beseitigen, ohne hierzu eine zusätzliche Wärmequelle installieren zu müssen. Zugleich soll ein Temperieren der Druckfarbe, Stabilisieren der Farb-Feuchtmittelemulsion und ein Korrosionsschutz der Fabkastenwalze erreicht werden.It is an object of the invention to eliminate local differences in thermal expansion in the ink fountain, the dosing means and in the ink fountain roller without having to install an additional heat source. At the same time, temperature control of the printing ink, stabilization of the ink fountain solution emulsion and corrosion protection of the ink fountain roller should be achieved.
Es wurde gefunden, daß dies auf einfache Weise erreicht wird, indem Unter- und Rückseite des Farbkastens mit einer Wärmeisolierung versehen werden und zusätzlich ein Warmluftstrom aus der Maschine auf der Farbkastenwalze zugewandte Seite des Farbkastens und die Dosierwalze des Farbkastens gerichtet wird.It has been found that this is achieved in a simple manner by providing the bottom and rear of the ink fountain with thermal insulation and in addition a warm air flow from the machine on the Ink fountain roller facing side of the ink fountain and the metering roller of the ink fountain is directed.
Die Wärmedämmung an der Unter- und Rückseite des Farbkastens reduziert die störende Erwärmung dieser Partien, die dem Warmluftstrom aus den Bogenführungseinrichtungen der Maschine besonders ausgesetzt sind.The thermal insulation on the bottom and back of the ink fountain reduces the annoying heating of these parts, which are particularly exposed to the hot air flow from the sheet guiding devices of the machine.
Die der Farbkastenwalze zugewandte Seite des Farbkastens wird in Abhängigkeit von den Einbauverhältnissen nur wenig von der warmen Maschinenluft getroffen. Diese Partie des Farbkastens hat dann eine niedrigere Temperatur als der übrige Farbkastenrumpf. Zum Temperaturausgleich wird der Warmluftstrom durch Ventilatoren und Leitbleche auf die dosierseitige Farbkastenkante gerichtet. Dadurch wird das Temperaturgefälle auf unter 1 Grad reduziert. Durch dieses geringe Temperaturgefälle treten entsprechend geringere Verspannungen im Farbkastenunterteil, den Dosierelementen und der Farbkastenwalze auf, d. h. der eingestellte Farbspalt unterliegt weniger Schwankungen in der Dicke, die vom Drucker leichter ausgeregelt werden können, ohne daß eine Temperaturregelung oder eine zusätzliche Heizung erforderlich sind.The side of the ink fountain facing the ink fountain roller is only slightly affected by the warm machine air, depending on the installation conditions. This part of the ink fountain is then at a lower temperature than the rest of the ink fountain body. To equalize the temperature, the hot air flow is directed by fans and baffles at the ink fountain edge on the metering side. This reduces the temperature gradient to less than 1 degree. Due to this low temperature gradient, correspondingly lower tensions occur in the ink fountain lower part, the metering elements and the ink fountain roller, i.e. H. the set color gap is subject to fewer fluctuations in the thickness, which can be more easily adjusted by the printer without the need for temperature control or additional heating.
Außer dem bereits beschriebenen Vermeiden der Wärmedehnungen bewirkt die Erfindung noch ein Temperieren der Druckfarbe sowie ein Stabilisieren der Farb- Feuchtmittelemulsion. Da sich die Luft aus den Bogenführungssystemen der Maschine schon nach kurzer Betriebszeit erwärmt, wird durch das Anblasen der Farbkastenwalze eine Temperierung der Druckfarbe erreicht. Aufgrund dieser Temperierung zeigt die Druckfarbe in der Warmlaufphase der Maschine ein deutlich gleichmäßigeres Viskositätsverhalten, das ebenfalls wichtig für konstante Farbführung ist.In addition to avoiding the thermal expansions already described, the invention also brings about a temperature control of the printing ink and a stabilization of the ink / fountain solution emulsion. Since the air from the sheet guiding systems of the machine heats up after a short period of operation, the ink is heated by blowing on the ink fountain roller. Because of this temperature control, the printing ink shows a much more uniform viscosity behavior in the warm-up phase of the machine, which is also important for constant Color guide is.
Nach längerer Betriebszeit der Maschine verhindert die Warmluftzufuhr zum Farbduktor eine übermäßige Anreicherung von Feuchtmittel in der Druckfarbe. Ein erhöhter Feuchtmittelgehalt kann zu Korrosionserscheinungen am Farbduktor und Farbdosierelementen führen. Aufwendige Beschichtungen der Farbkastenwalze mit korrosionsbeständigen Werkstoffen sind nicht erforderlich.After the machine has been in operation for a long time, the supply of warm air to the ink duct prevents excessive accumulation of dampening solution in the printing ink. An increased dampening solution content can lead to signs of corrosion on the ink fountain and ink metering elements. Elaborate coatings on the ink fountain roller with corrosion-resistant materials are not necessary.
Die Erfindung wird nachstehend anhand der Zeichnung in einem Ausführungsbeispiel erläutert.The invention is explained below with reference to the drawing in one embodiment.
Es zeigen:

- FIG. 1 shows the side view of the ink fountain,
- 2 shows the view X of the ink fountain according to FIG. 1.
Der in den Figuren 1 und 2 dargestellte Farbkasten 2 ist beidseitig auf Trägern abgesetzt, die durch eine Traverse 5 verbunden sind und kann über hier nicht näher dargestellte Schienen des Maschinengestells in die Maschine als Ganzes eingeschoben werden. Diese Betriebsstellung ist durch nicht dargestellte Anschläge definiert, die die Einschubbewegung beenden.The
Der Farbkasten 2 ist über nicht dargestellten Drehpunkt von der Farbkastenwalze 1 abschwenkbar angeordnet. Die Begrenzung des Farbkastens 2 an den beiden Stirnseiten erfolgt in bekannter Weise durch jeweils ein Farbkastenseitenteil, dessen Stirnfläche mit einer der Oberflächenkrümmung der Farbkastenwalze 1 entsprechenden Ausnehmung versehen ist. Dadurch wird ein Auslaufen der Farbe in dem Kontaktierungsbereich verhindert. Die Schwenkbewegung des Farbkastens 2 zur Farbkastenwalze 1 erfolgt über einen nicht dargestellten Kniehebel und ein Schwenkgetriebe ebenfalls in bekannter Weise.The
Um das teilweise gegenseitige Aufheben der Wärmedehnungen im Farbkasten, den nicht näher bezeichneten Dosiermitteln z. B. einem Farbmesser und der Farbkastenwalze zu ermöglichen, ohne hierzu zusätzliche Wärmequellen zu benötigen, ist die Unterseite des Farbkastenrumpfes mit einer Wärmedämmung 6 versehen. Ein mittlerer Bereich (1/2) der der Farbkastenwalze 1 zugewandten Seite des Farbkastenrumpfes wird von einem Warmluftstrom in der Betriebszeit der Druckmaschine entstehender Wärme verstärkt durch Ventilatoren 3 beaufschlagt. Die Ventilatoren 3 sind in der Nähe einer in der Betriebszeit in der Druckmaschine entstehenden Wärmequelle, z. B. unterhalb des Farbkastens 2 oberhalb einer Bogenführungstrommel angeordnet, so daß die Warmluftströmung aus dieser Trommel auf diesen Bereich des Farbkastens 2 einwirkt. Damit die Wärme mit dem durch die Ventilatoren 3 erzeugten hohen Volumenstrom möglichst verlustfrei dem mittleren Bereich (1/2) der Farbkastenwalze 1 zugewandten Seite des Farbkastenrumpfes zugeführt werden kann, sind die Ventilatoren 3 von einer Leitvorrichtung 4 umgeben, derart, daß die Warmluft dem genannten mittleren Bereich exakt in den Spalt zwischen der Farbkastenwalze 1 und der dieser zugewandten Seite des Farbkastenrumpfes gelangt. Auf diese Weise werden alle wesentlichen Teile des Farbkastens 2 gleichmäßig umspült.In order to partially cancel each other out of the thermal expansions in the ink fountain, the unspecified dosing agents such. B. to enable an ink knife and the ink fountain roller without the need for additional heat sources, the underside of the ink fountain fuselage is provided with
