Definitions
- the invention relates to a washing device for a blanket cylinder of a printing machine with a tub for a washing liquid, with a drivable on rotation, can be brought into contact with the blanket cylinder and provided with a cover, and also with a plurality of axially spaced, attached to a wall of the tub Spray nozzles for spraying the washing roller with the washing liquid, and with a doctor blade arranged parallel to the axis of the washing roller, which is held on the tub and which is operatively connected to a plurality of adjusting screws which are screwed into the wall of the tub distributed over the length of the doctor blade.
- a washing device with these features is described in DE-39 03 434 C2.
- a plurality of stop pins are screwed into the front wall of the trough, the tips of which rest on the top of the squeegee.
- several further stop screws are also screwed into the front wall of the trough, the tips of which abut the rear wall of the squeegee.
- the doctor blade is thus supported in two directions by means of these two setscrew systems, namely against bending upwards and forwards towards the front wall of the tub.
- German utility model 70 05 448 which describes a roller doctor blade of a coating device which is supported on its side facing away from the coating cylinder by a plurality of pneumatic pistons which are spaced apart in the longitudinal direction of the doctor blade.
- an approximately semi-cylindrical receptacle is formed in the front of each pneumatic piston, in which the doctor blade is inserted.
- the roller doctor is supported upwards and downwards and also in a direction of force away from the cylinder, but not in a direction of force towards the cylinder.
- unpleasant vibrations can occur in operation, which have a negative effect on the quality of the product produced with them.
- the US 35 21 561 describes a color meter of a printing cylinder, the deflection of which can be adjusted with the aid of a plurality of spaced screws, that is to say in the tangential direction of the cylinder. An adjustment in the radial direction is not possible with this known construction.
- a washing device is known from EP 0 535 356 A1, cited in accordance with Article 54 (3) and (4) EPC, the doctor blade of which is attached to the Trough is held and is operatively connected to the washing roller by means of several adjusting screws.
- an inking unit is known, the washing roller of which is in contact with an inking roller.
- the doctor blade is not in operative connection with the washing roller, but with the inking roller.
- an inking unit is known from US Pat. No. 3,559,573, the ink slides of which are operatively connected to an ink fountain roller by means of adjusting screws.
- the invention is therefore based on the object to propose a washing device with the features of the preamble of claim 1, with the aid of which it is possible to set the position of the doctor blade very precisely without the disadvantageous vibrations and chatter phenomena described occurring during operation.
- the invention is characterized in that the set screws are positively connected to the squeegee.
- connection of the set screws to the squeegee means that a movement of these two parts against one another is not possible or is only possible to a limited extent in the elastic range. If the transferable force is exceeded, the connection would be destroyed.
- the set screws are form-fitting engage in blind holes in the squeegee.
- the blind holes are therefore only accessible to the side of the tub front wall and the material of the doctor blade therefore surrounds the blind holes from all other sides, so that the material of the doctor blade on these sides prevents any movement of the doctor blade relative to the adjusting screws. Movement in the longitudinal direction of the set screws is reliably prevented by the positive connection of the two parts.
- a preferred embodiment is characterized in that the set screws have two threaded sections with different pitches, with which they are screwed into corresponding counter threads in the wall of the tub or in the squeegee. If you turn the adjusting screw, these measures cause the doctor blade to be turned on or off the washing roller and the threaded connection simultaneously produces the necessary positive connection between these two parts.
- the washing device shown is mounted such that it can be tilted about an axis 2, so that it can be placed on a blanket cylinder (not shown in the drawing) or set down by it.
- the washing device has a tub 3 and in the tub a rotatably mounted and driven washing roll 4, the direction of rotation of which is indicated in FIG. 2 by the arrow 5.
- a plurality of spray nozzles 7 are fixed axially spaced apart, which direct a spray jet of the detergent onto the washing roller 4, but not onto the bottom of the tub.
- a doctor blade 8 which has blind bores 9 with threaded sections spaced apart from one another, into which set screws 10 are screwed with their front threaded sections.
- the set screws have further threaded sections 11, with which they are screwed into corresponding counter threads in the front wall 6 of the tub or into bushings inserted there.
- sheets 12, 13 are arranged in the tub for draining off the washing or spraying water.
- the threaded sections 9, 11 of the set screws 10 have different pitches. So if you turn the set screws, the squeegee 8 is placed in the longitudinal direction of the set screws on the washing roller 4 or switched off by it. This is done zone by zone via the plurality of adjusting screws 10 which are spaced apart from one another.
- the respectively set position of the set screws can be fixed via nuts 14.
- the doctor blade 8 can be finely adjusted zone by zone with the aid of the adjusting screws 10 with differential threads 9, 11 arranged in zones, whereby it is held on all sides by the adjusting screws in a force-fitting and positive manner.
- the described vibrations and chatter phenomena which are disadvantageous in the prior art, can no longer occur. This is achieved inexpensively using a single system of set screws or zone screws.

Description
Die Erfindung betrifft eine Waschvorrichtung für einen Gummituchzylinder einer Druckmaschine mit einer Wanne für eine Waschflüssigkeit, mit einer auf Drehung antreibbaren, in Berührung mit dem Gummituchzylinder bringbaren und mit einem Bezug versehenen Waschwalze, ferner mit mehreren, axial beabstandet angeordneten, an einer Wand der Wanne befestigten Sprühdüsen zur Sprühbeaufschlagung der Waschwalze mit der Waschflüssigkeit, und mit einer achsparallel zu der Waschwalze angeordneten Rakel, die an der Wanne gehalten ist und die mit mehreren Stellschrauben in Wirkverbindung steht, die über die Länge der Rakel verteilt in die Wand der Wanne eingeschraubt sind.The invention relates to a washing device for a blanket cylinder of a printing machine with a tub for a washing liquid, with a drivable on rotation, can be brought into contact with the blanket cylinder and provided with a cover, and also with a plurality of axially spaced, attached to a wall of the tub Spray nozzles for spraying the washing roller with the washing liquid, and with a doctor blade arranged parallel to the axis of the washing roller, which is held on the tub and which is operatively connected to a plurality of adjusting screws which are screwed into the wall of the tub distributed over the length of the doctor blade.
Eine Waschvorrichtung mit diesen Merkmalen beschreibt die DE-39 03 434 C2. Um zu verhindern, daß die Rakel beim Herandrücken an den Waschwalzenbezug sich aufgrund der Reibungskräfte in Richtung der Drehbewegung der Waschwalze durchbiegt, sind in die Vorderwand der Wanne mehrere Anschlagstifte eingeschraubt, die mit ihren Spitzen auf der Oberseite der Rakel aufliegen. Zur Verhinderung eines Abdrückens sind mehrere weitere Anschlagschrauben ebenfalls in die Vorderwand der Wanne eingeschraubt, die mit ihren Spitzen an der Rückwand der Rakel anliegen. Durch diese beiden Stellschraubensysteme wird die Rakel somit in zwei Richtungen gestützt, nämlich gegen ein Durchbiegen nach oben und nach vorne zur Vorderwand der Wanne. In der Patentschrift steht zwar, daß die beiden Schraubensysteme auch das Auftreten von Schwingungen oder Rattererscheinungen im Betrieb der Waschvorrichtung verhindern sollen, jedoch hat die Praxis gezeigt, daß dies nicht derA washing device with these features is described in DE-39 03 434 C2. In order to prevent the squeegee from bending due to the frictional forces in the direction of the rotary motion of the washing roller when it is pressed against the washing roller cover, a plurality of stop pins are screwed into the front wall of the trough, the tips of which rest on the top of the squeegee. To prevent pulling off, several further stop screws are also screwed into the front wall of the trough, the tips of which abut the rear wall of the squeegee. The doctor blade is thus supported in two directions by means of these two setscrew systems, namely against bending upwards and forwards towards the front wall of the tub. Although the patent states that the two screw systems are also intended to prevent the occurrence of vibrations or chatter during operation of the washing device, practice has shown that this is not the case
Fall ist. Dies liegt daran, daß die Rakel sich nach unten und nach hinten in Richtung der Waschwalze frei bewegen kann, weil nämlich der Waschwalzenbezug einer Bewegung nach hinten keinen richtigen Widerstand entgegensetzt. Hier ist auch zu beachten, daß die aktive Kante der Rakel Unebenheiten aufweisen kann bzw. sich im Laufe ihrer Betriebszeit abnutzt. Dasselbe gilt für die Waschwalze bzw. deren Bezug.Case is. This is because the squeegee can move freely downwards and backwards in the direction of the washing roller, because the washing roller cover does not offer any real resistance to a movement backwards. It should also be noted here that the active edge of the squeegee may have unevenness or wear out in the course of its operating time. The same applies to the washing roller or its cover.
Zum Stand der Technik wird auch verwiesen auf die deutsche Gebrauchsmusterschrift 70 05 448, die eine Rollrakel einer Streichvorrichtung beschreibt, die an ihrer vom Streichzylinder abgewandten Seite von mehreren, in Längsrichtung der Rakel beabstandet angeordneten Pneumatikkolben gestützt wird. Hierzu ist in der Vorderseite jedes Pneumatikkolbens eine etwa halbzylindrische Aufnahme ausgebildet, in der die Rollrakel eingesetzt ist. Dadurch wird die Rollrakel zwar nach oben und nach unten und auch in einer Kraftrichtung hinweg vom Zylinder gestützt, nicht aber in einer Kraftrichtung in Richtung auf den Zylinder zu. Auch hier kann es im Betrieb daher zu unangenehmen Vibrationen kommen, die sich nachteilig auf die Qualität des damit hergestellten Produkts auswirken.With regard to the prior art, reference is also made to German utility model 70 05 448, which describes a roller doctor blade of a coating device which is supported on its side facing away from the coating cylinder by a plurality of pneumatic pistons which are spaced apart in the longitudinal direction of the doctor blade. For this purpose, an approximately semi-cylindrical receptacle is formed in the front of each pneumatic piston, in which the doctor blade is inserted. As a result, the roller doctor is supported upwards and downwards and also in a direction of force away from the cylinder, but not in a direction of force towards the cylinder. Here, too, unpleasant vibrations can occur in operation, which have a negative effect on the quality of the product produced with them.
Die US 35 21 561 beschreibt ein Farbmesser eines Druckzylinders, das mit Hilfe von mehreren voneinander beabstandet angeordneten Schrauben in seiner Durchbiegung verstellt werden kann, also in tangentialer Richtung des Zylinders. Eine Verstellung in radialer Richtung ist mit dieser bekannten Konstruktion nicht möglich.The US 35 21 561 describes a color meter of a printing cylinder, the deflection of which can be adjusted with the aid of a plurality of spaced screws, that is to say in the tangential direction of the cylinder. An adjustment in the radial direction is not possible with this known construction.
Aus der EP 0 535 356 A1, gemäß Artikel 54 (3) und (4) EPÜ zitiert, ist eine Waschvorrichtung bekannt, deren Rakel an der Wanne gehalten ist und mittels mehrerer Stellschrauben in Wirkverbindung mit der Waschwalze steht.A washing device is known from EP 0 535 356 A1, cited in accordance with Article 54 (3) and (4) EPC, the doctor blade of which is attached to the Trough is held and is operatively connected to the washing roller by means of several adjusting screws.
Nach der US 2,363,817 ist ein Farbwerk bekannt, dessen Waschwalze mit einer Farbwalze in Kontakt steht. Die Rakel steht dabei nicht mit der Waschwalze, sondern mit der Farbwalze in Wirkverbindung.According to US 2,363,817, an inking unit is known, the washing roller of which is in contact with an inking roller. The doctor blade is not in operative connection with the washing roller, but with the inking roller.
Weiterhin ist aus der US 3,559,573 ein Farbwerk bekannt, dessen Farbschieber mittels Stellschrauben mit einer Farbkastenwalze in Wirkverbindung stehen.Furthermore, an inking unit is known from US Pat. No. 3,559,573, the ink slides of which are operatively connected to an ink fountain roller by means of adjusting screws.
Ausgehend von dem vorstehend geschilderten Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, eine Waschvorrichtung mit den Merkmalen des Oberbegriffs von Patentanspruch 1 vorzuschlagen, mit deren Hilfe es möglich ist, die Position der Rakel sehr genau einzustellen, ohne daß es im Betrieb zu den geschilderten nachteiligen Schwingungen und Rattererscheinungen kommt.Starting from the prior art described above, the invention is therefore based on the object To propose a washing device with the features of the preamble of
Zur Lösung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, daß die Stellschrauben formschlüssig mit der Rakel verbunden sind.To achieve this object, the invention is characterized in that the set screws are positively connected to the squeegee.
Man kann also jede der Stellschrauben um ein gewünschtes Maß verstellen, d.h. an die Waschwalze anstellen bzw. von ihr abstellen, wobei die Rakel allseits von den Stellschrauben formschlüssig und kraftschlüssig gehalten ist. Im Gegensatz zum Stand der Technik nach DE 39 03 434 C2 kommt man mit einem einzigen System der Stellschrauben aus und erzielt trotz dieser fühlbaren konstruktiven Vereinfachung ein wesentlich besseres Ergebnis, weil man die Rakel auch abstellen kann und weil insgesamt undefinierte Verbiegungen und Ausrichtungen der Rakel vermieden werden. Ein definiertes Zurückholen der Rakel ist auch mit dem vorstehend diskutierten System nach der erwähnten Gebrauchsmusterschrift nicht möglich, wohl aber mit dem erfindungsgemäßen System.So you can adjust each of the adjusting screws by a desired amount, i.e. Place on the washing roller or place it off, the squeegee being held positively and non-positively on all sides by the adjusting screws. In contrast to the prior art according to DE 39 03 434 C2, a single system of adjusting screws is sufficient and, despite this noticeable structural simplification, a much better result is achieved because the squeegee can also be switched off and because overall undefined bends and alignments of the squeegee are avoided become. A defined return of the doctor blade is not possible with the system discussed above according to the utility model mentioned, but it is possible with the system according to the invention.
Die erfindungsgemäß vorgesehene formschlüssige Verbindung der Stellschrauben mit der Rakel bedeutet, daß eine Bewegung dieser beiden Teile gegeneinander nicht bzw. nur im elastischen Bereich beschränkt möglich ist. Bei Überschreiten der übertragbaren Kraft würde die Verbindung zerstört.The positive connection of the set screws to the squeegee provided according to the invention means that a movement of these two parts against one another is not possible or is only possible to a limited extent in the elastic range. If the transferable force is exceeded, the connection would be destroyed.
Bevorzugt wird es, wenn die Stellschrauben formschlüssig in Sackbohrungen der Rakel eingreifen. Die Sackbohrungen sind also nur zur Seite der Wannenvorderwand zugänglich und das Material der Rakel umgibt also die Sackbohrungen von allen anderen Seiten, so daß das Material der Rakel zu diesen Seiten jedwede Bewegung der Rakel relativ zu den Stellschrauben verhindert. Eine Bewegung in Längsrichtung der Stellschrauben wird durch die formschlüssige Verbindung der beiden Teile sicher verhindert.It is preferred if the set screws are form-fitting engage in blind holes in the squeegee. The blind holes are therefore only accessible to the side of the tub front wall and the material of the doctor blade therefore surrounds the blind holes from all other sides, so that the material of the doctor blade on these sides prevents any movement of the doctor blade relative to the adjusting screws. Movement in the longitudinal direction of the set screws is reliably prevented by the positive connection of the two parts.
Für die formschlüssige Verbindung der beiden Teile miteinander gibt es mehrere Möglichkeiten. Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß die Stellschrauben zwei Gewindeabschnitte mit unterschiedlichen Steigungen haben, mit denen sie in entsprechende Gegengewinde in der Wand der Wanne bzw. in der Rakel eingeschraubt sind. Dreht man die Stellschraube, so wird durch diese Maßnahmen bewirkt, daß die Rakel an die Waschwalze an- bzw. abgestellt wird und durch die Gewindeverbindung wird gleichzeitig die notwendige formschlüssige Verbindung zwischen diesen beiden Teilen hergestellt.There are several options for the positive connection between the two parts. A preferred embodiment is characterized in that the set screws have two threaded sections with different pitches, with which they are screwed into corresponding counter threads in the wall of the tub or in the squeegee. If you turn the adjusting screw, these measures cause the doctor blade to be turned on or off the washing roller and the threaded connection simultaneously produces the necessary positive connection between these two parts.
