Description

Die Erfindung betrifft einen Wasserkasten für ein Feuchtwerk einer Offset-Rotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a water tank for a dampening unit of an offset rotary printing press according to the preamble of patent claim 1.

Derartige Einrichtungen in Feuchtwerken von Offset-Rotationsdruckmaschinen sind in verschiedenen Bauarten bekannt. Die US-PS 30 45 592 zeigt einen Wasserkasten mit einem Wehr zur Regulierung eines Feuchtflüssigkeitsstandes. Das Wehr ist mit Ausnehmungen, die ein Leerlaufen des Wasserkastens ermöglichen, ausgerüstet.Devices of this type in dampening units of offset rotary printing presses are known in various designs. The US-PS 30 45 592 shows a water tank with a weir for regulating a moisture level. The weir is equipped with recesses that allow the water tank to drain.

Es ist aber auch bekannt, daß Duktorwalzen Papierabrieb in den Wasserkasten fördern. Dieser Papierabrieb setzt sich am Boden des Wasserkastens als Schlamm ab. Um diesen Schlamm zu entfernen, muß der Wasserkasten zum Reinigen ausgebaut werden. Hierzu müssen in nachteiliger Weise Zu- und Ablaufschläuche demontiert werden, was zu längeren Maschinenstillstandzeiten führt.But it is also known that ductor rollers promote paper abrasion in the water tank. This paper debris deposits as sludge at the bottom of the water tank. To remove this sludge, the water tank must be removed for cleaning. For this purpose, inlet and outlet hoses have to be dismantled disadvantageously, which leads to longer machine downtimes.

Der Erfindung liegt die Aufgabe zugrunde, einen Wasserkasten für ein Feuchtwerk einer Offset-Rotationsdruckmaschine zu schaffen, der ohne ein Lösen von Schläuchen oder Rohren aus der Maschine herausgenommen werden kann.The invention has for its object to provide a water tank for a dampening unit of an offset rotary printing press, which can be removed from the machine without loosening hoses or tubes.

Die Aufgabe wird erfindungsgemäß durch den kennzeichnenden Teil des Patentanspruchs 1 gelöst.The object is achieved by the characterizing part of patent claim 1.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß kurze prozeß-, produktions-, oder maschinenbedingte Stillstände zur Reinigung des Wasserkastens genutzt werden können. Da der Wasserkasten mit erfindungsgemäß gestalteten Wehren ausgestattet ist, hat die Oberflächenspannung der Feuchtflüssigkeit keinen Einfluß auf die gleichmäßige Strömung der Feuchtflüssigkeit im Wasserkasten. Dies führt zu einem gleichmäßigen Überlaufen der Wehre und damit zu einem gleichmäßigen Ablaufen der Feuchtflüssigkeit aus dem Wasserkasten.The advantages that can be achieved with the invention are, in particular, that short process, production or machine-related downtimes can be used for cleaning the water tank. Since the water tank is equipped with weirs designed according to the invention, the surface tension of the dampening liquid has no influence on the uniform flow of the dampening liquid in the water box. This leads to a uniform overflow of W honor and thus to a uniform drainage of the dampening fluid from the plenum chamber.

In besonders vorteilhafter Weise kann ein Luftstau in der Abflußleitung und ein dadurch verursachtes Überlaufen des Wasserkastens auf einfache Weise vermieden werden.In a particularly advantageous manner, an air congestion in the drain line and a resulting overflow of the water tank can be avoided in a simple manner.

Eine Ausführung der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Seitenansicht des aufgeschnittenen, erfindungsgemäßen Wasserkastens,
  • Fig. 2 eine Draufsicht des Wasserkastens nach Fig. 1.
An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it:
  • 1 is a side view of the cut, water box according to the invention,
  • FIG. 2 shows a top view of the water tank according to FIG. 1.

Ein Wasserkasten 1 einer Offset-Rotationsdruckmaschine besteht aus einer Vorderwand 2, einer linken Seitenwand 3, einer Rückwand 4, einer rechten Seitenwand 6 und einem Boden 7. Die Wände 2, 3, 4 und 6 haben alle eine gleiche Höhe k bezogen auf den Boden 7. Die Wände 2, 3 und 6 stehen senkrecht auf dem Boden 7. Ein Öffnungswinkel ß zwischen der Rückwand 4 und dem Boden 7 beträgt z.B. 135°. In einer linken vorderen Ecke 8, die durch die Wände 2 und 3 gebildet wird, weist der Wasserkasten 1 im Boden 7 ein kreisrundes Loch 9 auf. Ein Ablaufstutzen 11, der mit einer Innenfläche 12 des Bodens 7 bündig abschließt, ist in das Loch 9 eingeschweißt. Der Ablaufstutzen 11 besteht aus einem ca. 15mm langen Rohrstück 20 x 1. Parallel zu der Vorderwand 2 ist in einem Abstand a zur Vorderwand 2 ein, sich über eine gesamte Länge des Wasserkastens 1 erstreckendes, senkrechtes Auslaufwehr 13 angebracht.A water box 1 of an offset rotary printing press consists of a front wall 2, a left side wall 3, a rear wall 4, a right side wall 6 and a floor 7. The walls 2, 3, 4 and 6 all have the same height k with respect to the floor 7. The walls 2, 3 and 6 are perpendicular to the floor 7. An opening angle β between the rear wall 4 and the floor 7 is, for example, 135 °. In a left front corner 8 formed by walls 2 and 3 the water tank 1 has a circular hole 9 in the bottom 7. A drain socket 11, which is flush with an inner surface 12 of the bottom 7, is welded into the hole 9. The drain pipe 11 consists of an approximately 15 mm long piece of pipe 20 x 1. Parallel to the front wall 2 at a distance a from the front wall 2, a vertical outlet weir 13 extending over an entire length of the water tank 1 is attached.

Ein oberer Teil 14 des Auslaufwehrs 13 ist zur Vorderwand 2 hin in einem Winkel α von z.B. 45° abgewinkelt. In seinem oberen Teil 14 weist das Auslaufwehr 13 halbkreisförmige Ausnehmungen 16 auf, die voneinander einen Abstand b haben. In einem geringen Abstand c vom Boden 7 weist das Auslaufwehr 13 eine Mehrzahl von Ablauflöchern 17 auf. Parallel zum Auslaufwehr 13 ist in einem Abstand d (ca. 8cm) vom Auslaufwehr 13 ein Einlaufwehr 18 angebracht, das sich über die gesamte Länge des Waserkastens 1 erstreckt. Das Einlaufwehr 18 steht senkrecht auf dem Boden 7, wobei ein oberer Teil 19 des Einlaufwehrs 18 zur Rückwand 4 hin in einem Winkel c6 von z.B. 45° abgewinkelt ist. An einem oberen Teil 19 weist das Einlaufwehr 18 eine Mehrzahl von halbkreisförmigen Ausnehmungen 21 auf, die zueinander einen Abstand e (ca. 20cm) haben. In einem geringen Abstand f vom Boden 7 des Wasserkasten 1 weist das Einlaufwehr 18 eine Mehrzahl kleiner Ablauflöcher 22 auf.An upper part 14 of the outlet weir 13 is towards the front wall 2 at an angle α of e.g. Angled 45 °. In its upper part 14, the outlet weir 13 has semicircular recesses 16 which are at a distance b from one another. At a short distance c from the floor 7, the outlet weir 13 has a plurality of drain holes 17. In parallel to the outlet weir 13, an inlet weir 18 is attached at a distance d (approx. 8 cm) from the outlet weir 13 and extends over the entire length of the water tank 1. The inlet weir 18 is perpendicular to the floor 7, with an upper part 19 of the inlet weir 18 towards the rear wall 4 at an angle c6 of e.g. Is angled 45 °. On an upper part 19, the inlet weir 18 has a plurality of semicircular recesses 21 which are at a distance e (approx. 20 cm) from one another. At a short distance f from the bottom 7 of the water tank 1, the inlet weir 18 has a plurality of small drain holes 22.

Eine Höhe g des Einlaufwehrs 18 ist größer als eine Höhe h des Auslaufwehrs 13 und kleiner als die Höhe k der Wände 2, 3, 4 und 6.A height g of the inlet weir 18 is greater than a height h of the outlet weir 13 and less than the height k of the walls 2, 3, 4 and 6.

Die Wände 3 und 6 sind über den Boden 7 hinaus nach unten hin verlängert und weisen jeweils vorne an ihrer Unterkante je eine hakenförmige Aufnahme 23, 24 auf. Mittels der Aufnahmen 23 und 24 wird der Wasserkasten 1 an in Seitengestellen 26 und 27 der Maschine befestigten Bolzen 28, 29 eingehängt. Hinten stützt sich der Wasserkasten 1 über seine nach unten verlängerten Wände 3 und 6 auf je einem in den Seitengestellen 26 bzw. 27 befestigten Bolzen 31 bzw. 32 ab.The walls 3 and 6 are extended downwards beyond the base 7 and each have a hook-shaped receptacle 23, 24 at the front edge on their lower edge. By means of the receptacles 23 and 24, the water tank 1 is suspended on bolts 28, 29 fastened in side frames 26 and 27 of the machine. At the rear, the water tank 1 is supported via its downwardly elongated walls 3 and 6, each on a bolt 31 and 32 fastened in the side frames 26 and 27, respectively.

Ein rohrförmiger Zulauf 33 für eine Feuchtflüssigkeit ist am linken Seitengestell 26 befestigt. Eine Öffnung 34 des Zulaufs 33 befindet sich über dem Wasserkasten 1 zwischen dem Einlaufwehr 18 und der Rückwand 4. Dicht unterhalb des Ablaufstutzens 11 ist koaxial zum Ablaufstutzen 11 und in einem Abstand m von ihm ein Trichter 39 angeordnet. Der Trichter 39 ist in ein gestellfestes Ablaufrohr 36 eingesteckt. Das Ablaufrohr 36 ist an einer gestellfesten Traverse 37 befestigt.A tubular inlet 33 for a dampening fluid is attached to the left side frame 26. An opening 34 of the inlet 33 is located above the water tank 1 between the inlet weir 18 and the rear wall 4. A funnel 39 is arranged coaxially to the outlet nozzle 11 and at a distance m from it, just below the outlet nozzle 11. The funnel 39 is inserted into a drain pipe 36 fixed to the frame. The drain pipe 36 is attached to a cross member 37 fixed to the frame.

Der Trichter 39 ist so gestaltet, daß sein kleinster Ablaufquerschnitt größer ist als ein größter Auslaufquerschnitt des Ablaufstutzens 11.The funnel 39 is designed such that its smallest outlet cross section is larger than a largest outlet cross section of the outlet connector 11.

Aus dem Zulauf 33 fließt eine Feuchtflüssigkeit zwischen dem Einlaufwehr 18 und der Rückwand 4 in den Wasserkasten 1 ein. Da ein Querschnitt des Zulaufs 33 größer ist als eine Summe der Querschnitte aller Ablauflöcher 22 im Einlaufwehr 18, staut sich die Feuchtflüssigkeit vor diesem auf, bis sie die Oberkante erreicht hat. Die Feuchtflüssigkeit fließt über die Ausnehmungen 21 des Einlaufwehrs 18 in einen Raum zwischen dem Einlaufwehr 18 und dem Auslaufwehr 13 ab und staut sich vor diesem bis zu dessen Oberkante auf. Die über die Ausnehmungen 16 des Auslaufwehrs 13 abfließende Feuchtflüssigkeit läuft durch den Ablaufstutzen 11 aus dem Wasserkasten 1 ab und wird über den Trichter 39 dem Ablaufrohr 36 zugeführt. Über das Ablaufrohr 36 fließt die Feuchtflüssigkeit zu einer handelsüblichen Feuchtflüssigkeitsumwälzanlage und von dort über Zuleitungsrohre und Zulauf 33 wieder in den Wasserkasten 1. Wird die Zufuhr von Feuchtflüssigkeit gestoppt, fließt die Feuchtflüssigkeit über die Ablauflöcher 17 und 22 und den Ablaufstutzen 11 aus dem Wasserkasten 1 ab. Der leere Wasserkasten 1 kann bequem und ohne Zuhilfenahme von Werkzeug aus dem Feuchtwerk einer Druckmaschine entnommen werden.A dampening liquid flows from the inlet 33 between the inlet weir 18 and the rear wall 4 into the water tank 1. Since a cross section of the inlet 33 is larger than a sum of the cross sections of all the outlet holes 22 in the inlet weir 18, the dampening liquid builds up in front of it until it has reached the upper edge. The dampening fluid flows through the recesses 21 of the inlet weirs 18 into a space between the inlet weir 18 and the outlet weir 13 and builds up in front of it up to its upper edge. The dampening liquid flowing out via the recesses 16 of the outlet weir 13 runs out of the water tank 1 through the outlet connection 11 and is fed to the outlet pipe 36 via the funnel 39. Via the drain pipe 36, the dampening liquid flows to a commercially available dampening liquid circulation system and from there via feed pipes and inlet 33 back into the water tank 1 . The empty water tank 1 can be conveniently removed from the dampening unit of a printing press without the aid of tools.
