Abstract

An offset printing machine has a half-tone roller (3) mounted above a trough from which ink is supplied by an inking roller. The ink trough is mounted on a support (9) which also supports two wiper blades (11,12). Each blade (11,12) is mounted loosely in a slot (15) formed in the support (9). The width of the slot exceeds the thickness of the blade by 0.03 to 0.04mm. The slot extends over the entire length of the blade support. When printing ink with a high viscosity is used, the friction between the wiper blades and the roller generates heat which causes the blades to expand. The clearance between blade and slot accommodates this expansion.

Description

Die Erfindung betrifft eine Rakeleinrichtung mit we­nigstens einem Rakelblatt, das auf einem Rakelhalter aufnehmbar ist.The invention relates to a doctor device with at least one doctor blade that can be received on a doctor holder.

Bei den bekannten Anordnungen dieser Art wird das Rakel­blatt fest eingespannt. Die Folge einer derartigen Ein­spannung ist, daß sich der eingespannte Bereich des Ra­kelblatts, das sich im Betrieb nicht unerheblich er­wärmt, nicht seitlich ausdehnen kann. Es kommt daher zu einer Welligkeit des nicht eingespannten, am abzu­rakelnden Zylinder anliegenden Bereichs des Rakelblatts. Um dennoch eine unexakte Anlage des Rakelblatts am ab­zurakelnden Zylinder zu vermeiden, ist es dabei erfor­derlich, das Rakelblatt mit hoher Kraft anzustellen. Dies führt aber zu einem schnellen Verschleiß des Ra­kelblatts, so daß eine häufige Nachstellung und ein häu­figer Rakelblattwechsel erforderlich werden. Die bekann­ten Anordnungen erweisen sich demnach als nicht bedie­nungsfreundlich und wirtschaftlich genug. Die obigen Nachteile treten bei der Verarbeitung von Offsetfarben besonders stark zutage, da hierbei infolge der hohen Farbviskosität eine sehr starke Erwärmung des Rakelblatts zu erwarten ist.In the known arrangements of this type, the doctor blade is firmly clamped. The consequence of such clamping is that the clamped area of the doctor blade, which heats up not inconsiderably during operation, cannot expand laterally. There is therefore a ripple in the area of the doctor blade which is not clamped and is in contact with the cylinder to be scraped off. In order to avoid inaccurate contact of the doctor blade with the cylinder to be doctored, it is necessary to apply the doctor blade with high force. However, this leads to rapid wear of the doctor blade, so that frequent readjustment and a frequent doctor blade change are necessary. The known arrangements therefore prove to be not user-friendly and economical enough. The above disadvantages are particularly evident when processing offset inks, because of the high Ink viscosity a very strong heating of the doctor blade is to be expected.

Hiervon ausgehend ist es daher die Aufgabe der vorlie­genden Erfindung, eine Rakeleinrichtung eingangs erwähn­ter Art mit einfachen und kostengünstigen Mitteln so zu verbessern, daß eine schonende und dennoch zuverlässige Betriebsweise gewährleistet ist.Proceeding from this, it is therefore the object of the present invention to improve a doctor device of the type mentioned at the outset with simple and inexpensive means in such a way that a gentle but nevertheless reliable mode of operation is ensured.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Rakelblatt lose in einen zugeordneten Einlegeschlitz des Rakelhalters einlegbar ist.This object is achieved in that the doctor blade can be inserted loosely into an associated insertion slot of the doctor holder.

Hierdurch wird erreicht, daß sich das Rakelblatt bzw. die Rakelblätter im Falle einer Erwärmung seitlich ausdehnen kann bzw. können, so daß auch bei geringer Anstellkraft und damit schonender Betriebsweise eine zuverlässige An­lage des Rakelblatts bzw. der Rakelblätter am abzurakeln­den Zylinder erreicht wird. Dies ist besonders dort von Vorteil, wo hochviskose Farben, wie Offsetfarben, verar­beitet werden, die zu einer starken Erwärmung des Rakel­blatts bzw. der Rakelblätter führen kann.This ensures that the doctor blade or the doctor blades can expand laterally in the event of heating, so that a reliable contact of the doctor blade or the doctor blades on the cylinder to be doctored is achieved even with low contact force and therefore gentle operation. This is particularly advantageous where high-viscosity inks, such as offset inks, are processed, which can lead to excessive heating of the doctor blade or the doctor blades.

Zweckmäßig kann dabei die lichte Weite des vorzugsweise über die ganze Länge des Rakelhalters durchgehenden Ein­legeschlitzes gegenüber der Dicke des zugeordneten Ra­kelblatts ein Übermaß von etwa 3/100mm bis 4/100mm auf­weisen. Diese Maßnahme ergibt trotz des erwünschten Aus­dehnungsfreiheitsgrads eine zuverlässige Rakelblattab­stützung.Appropriately, the inside width of the insertion slot, which preferably extends over the entire length of the doctor blade holder, can have an excess of about 3 / 100mm to 4 / 100mm compared to the thickness of the associated doctor blade. This measure results in a reliable doctor blade support despite the desired degree of freedom of expansion.

Vorteilhaft kann der Einlegeschlitz durch eine an den mit einer stufenförmigen Ausnehmung versehenen Rakel­halter ansetzbare Leiste begrenzt sein. Diese Maßnahme ermöglicht eine einfache Herstellung des Einlegeschlitzes.The insertion slot can advantageously be delimited by a bar that can be attached to the doctor holder provided with a step-shaped recess. This measure enables simple production of the insertion slot.

Bei einer Kammerrakel mit einem durch zwei Rakelblätter und an deren Stirnseiten anliegenden Dichtbacken begrenz­ten Farbaufnahmeraum kann eine weitere vorteilhafte Maß­nahme darin bestehen, daß die Dichtbacken in Längsrich­tung der Rakelblätter nachgiebig angeordnet, vorzugsweise federnd an die Rakelblätter andrückbar sein können. Hier­durch ist sichergestellt, daß im Falle einer Ausdehnung der Rakelblätter die Dichtbacken ausweichen können, wo­durch auch in diesem Falle eine Welligkeit der Rakelblät­ter verhindert wird.In the case of a chambered doctor blade with an ink receiving space delimited by two doctor blades and sealing jaws resting on their end faces, a further advantageous measure can be that the sealing jaws are arranged in a flexible manner in the longitudinal direction of the doctor blades, preferably being able to be pressed resiliently against the doctor blades. This ensures that in the event of expansion of the doctor blades, the sealing jaws can deflect, which also prevents ripple of the doctor blades in this case.

Weitere zweckmäßige Fortbildungen und vorteilhafte Aus­gestaltungen der übergeordneten Maßnahmen sind in den restlichen Unteransprüchen angegeben.Further expedient further training and advantageous refinements of the superordinate measures are specified in the remaining subclaims.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

In der Zeichnung zeigen:

  • Figur 1 eine schematische Darstellung eines Offset-­Kurzfarbwerks und
  • Figur 2 einen Schnitt durch eine Kammerrakel mit zwei lose angeordneten Rakelblättern.
The drawing shows:
  • Figure 1 is a schematic representation of an offset short inking unit and
  • Figure 2 shows a section through a chambered doctor blade with two loosely arranged doctor blades.

Das der Figur 1 zugrundeliegende Kurzfarbwerk besteht aus einer mit einem Plattenzylinder 1 zusammenwirkenden, gummierten Auftragwalze 2, die durch eine Rasterwalze 3 mit Farbe und durch ein Feuchtwerk 4 mit Feuchtmittel versorgt wird. Der Umfang der Rasterwalze 3, die einen Keramikbezug aufweisen kann, ist mit vergrößert ange­deuteten Näpfchen 5 und diese begrenzenden Stegen 6 ver­sehen. Die Näpfchen 5 werden mit Farbe gefüllt. Die Ste­ge 6 werden abgerakelt.The short inking unit on which FIG. 1 is based consists of a rubberized applicator roller 2 which interacts with a plate cylinder 1 and is supplied with ink by an anilox roller 3 and with dampening solution 4 by a dampening unit 4. The circumference of the anilox roller 3, which can have a ceramic cover, is provided with cups 5 indicated in an enlarged manner and webs 6 delimiting them. The cells 5 are filled with paint. The webs 6 are scraped off.

Die Farbzufuhr zur Rasterwalze 3 und die Abrakelung der Stege 6 erfolgen mittels einer in Figur 1 als Ganzes mit 7 bezeichneten Kammerrakel. Diese umfaßt, wie Figur 2 zeigt, einen auf gestellfesten Trägern 8 aufgenommenen, balkenförmigen Rakelhalter 9, auf dem zwei in Drehrich­tung der Rasterwalze gegeneinander versetzte Rakelblätter 11, 12 aufgenommen sind. Diese begrenzen eine Farbauf­nahmekammer 13, die mittels einer Pumpe 16 mit Offset­farbe versorgt wird. Das in Drehrichtung der Rasterwalze 3 hintere Rakelblatt 11 wirkt als Vorrakel, das von einer Ableitrinne 14 unterfaßt ist. Das andere Rakelblatt 12 wirkt als Schließrakel. Beide Rakelblätter sind im dar­gestellten Ausführungsbeispiel mit negativem Anstellwin­kel angeordnet.The ink supply to the anilox roller 3 and the scraping of the webs 6 take place by means of a chamber doctor blade designated as a whole in FIG. 1. As shown in FIG. 2, this comprises a bar-shaped doctor holder 9 which is accommodated on supports 8 fixed to the frame and on which two doctor blades 11, 12 which are offset with respect to one another in the direction of rotation of the anilox roller are accommodated. These limit an ink receiving chamber 13, which is supplied with offset ink by means of a pump 16. The doctor blade 11, which is at the rear in the direction of rotation of the anilox roller 3, acts as a preliminary doctor, which is covered by a discharge channel 14. The other doctor blade 12 acts as a closing doctor. In the exemplary embodiment shown, both doctor blades are arranged with a negative angle of attack.

Die Rakelblätter 11, 12, die infolge der hohen Viskosität von Offsetfarbe einer hohen Erwärmung unterliegen, sind lose, d. h. ohne Klemmung, auf dem Rakelhalter 9 aufge­nommen. Dieser ist mit den Rakelblättern 11, 12 jeweils zugeordneten, über seine ganze Länge durchgehenden Ein­legeschlitzen 15 versehen. Hierzu ist der Rakelhalter 9 im Bereich seiner Flanken mit jeweils einer stufenförmigen Ausnehmung versehen, die jeweils durch eine an den Rakel­halter 9 angesetzte Leiste 10 so geschlossen wird, daß sich der nutförmige Einlegeschlitz 15 ergibt. Die lichte Weite der Einlegeschlitze 15 besitzt gegenüber der Dicke des jeweils zugeordneten Rakelblatts ein Übermaß von et­wa 3/100mm bis 4/100mm.The doctor blades 11, 12, which are subject to high heating due to the high viscosity of offset ink, are received loosely, ie without clamping, on the doctor holder 9. This is provided with squeegee blades 11, 12, each of which has insertion slots 15 that extend over its entire length. For this purpose, the doctor holder 9 is in the region of its flanks, each with a step-shaped Provide recess, which is closed by a bar 10 attached to the doctor holder 9 so that the groove-shaped insertion slot 15 results. The clear width of the insertion slots 15 has an excess of approximately 3 / 100mm to 4 / 100mm compared to the thickness of the doctor blade assigned in each case.

Rakelblätter 11, 12 erstrecken sich ebenfalls über die ganze Länge des Rakelhalters 9. Im Bereich der Stirn­seiten des Rakelhalters 9 wird die Farbaufnahmekammer 3 durch am Umfang der Rasterwalze 3 und an den Stirnseiten der Rakelblätter 11, 12 anliegende Dichtbacken 43 be­grenzt. Diese werden durch mit ihren Seitenkanten in ent­sprechende, am Rakelhalter 9 vorgesehene Führungen 46 einsteckbare Bleche gebildet. Die lichte Weite der Füh­rungen 46 besitzt gegenüber der Dicke der Dichtbacken 43 so viel Übermaß in Längsrichtung der Rakelblätter 11, 12, daß im Falle einer Ausdehnung der Rakelblätter 11, 12 ein entsprechendes Ausweichen der Dichtbacken 43 mög­lich ist. Diese werden federnd an die Stirnseiten der Rakelblätter 11, 12 angedrückt. Hierzu werden die Dicht­backen 43 im Bereich ihrer Anlage an den Rakelblattstirn­seiten von fingerförmigen Widerlagern 44 hinterfaßt, die in Längsrichtung der Rakelblätter 11, 12 federnd am Ra­kelhalter 9 abgestützt sind, wie bei 45 angedeutet ist.Doctor blades 11, 12 also extend over the entire length of the doctor holder 9. In the area of the end faces of the doctor holder 9, the ink-receiving chamber 3 is delimited by sealing jaws 43 resting on the circumference of the anilox roller 3 and on the end faces of the doctor blades 11, 12. These are formed by their side edges in corresponding, 46 provided on the doctor holder 9 guides 46 insertable plates. The clear width of the guides 46 has so much excess in the longitudinal direction of the doctor blades 11, 12 compared to the thickness of the sealing jaws 43 that a corresponding evasion of the sealing jaws 43 is possible in the event of an expansion of the doctor blades 11, 12. These are pressed resiliently onto the end faces of the doctor blades 11, 12. For this purpose, the sealing jaws 43 are gripped in the area of their abutment on the doctor blade end faces by finger-shaped abutments 44, which are resiliently supported in the longitudinal direction of the doctor blades 11, 12 on the doctor holder 9, as indicated at 45.
