Description

Die Erfindung betrifft eine Vorrichtung zum Verfahren von zwei auf in Schlittenführungen verschieblichen und Wellen lagernden Schlitten, vorzugsweise zum Verfahren der Lagerböcke von Druckzylindern und Raster- bzw. Farbauftragswalzen eines Druckwerks, mittels Spindeltrieben.The invention relates to a device for moving two slides, which are displaceable in slide guides and are supported by shafts, preferably for moving the bearing blocks of printing cylinders and anilox or inking rollers of a printing unit, by means of spindle drives.

Bei einer aus DE-43 08 711 A1 bekannten Vorrichtung dieser Art sind in dem ersten Schlitten zwei als Zahnriemenscheiben ausgebildete Spindelmuttern parallel zueinander und frei drehbar und die in diese eingeschraubten Spindeln frei drehbar und feststellbar einmal in dem Maschinengestell und zum anderen in dem zweiten Schlitten gelagert, wobei in dem ersten Schlitten eine von einem Motor antreibbare und durch eine Feststelleinrichtung fixierbare Antriebsriemenscheibe gelagert ist, die einen endlosen, die als Zahnriemenscheiben ausgebildeten Spindelmuttern antreibenden Zahnriemen antreibt. Mit dieser bekannten Vorrichtung lassen sich der Druckzylinderschlitten und der Rasterwalzenschlitten einer Flexodruckmaschine in der Weise relativ zu dem Maschinengestell verfahren, daß der Rasterwalzenschlitten sich relativ zu dem Gestell mit der doppelten Geschwindigkeit des Druckzylinderschlittens bewegt. Dadurch kann in einfacher Weise ein Druckzylinderwechsel vorgenommen werden, wobei bei dem Anstellen der Walzen im Druckbetrieb diese eine Lage zueinander annehmen, bei der der Druckzylinder den Gegendruckzylinder und die Rasterwalze den Druckzylinder berührt. Die bekannte Vorrichtung ist sowohl in ihrem Aufbau als auch ihrer Steuerung verhältnismäßig aufwendig.In a device of this type known from DE-43 08 711 A1, two spindle nuts designed as toothed belt pulleys are parallel to one another and freely rotatable in the first slide, and the spindles screwed into them are freely rotatable and lockable once in the machine frame and secondly in the second slide , in which a drive pulley, which can be driven by a motor and can be fixed by a locking device, is mounted in the first carriage and drives an endless toothed belt which drives the spindle nuts designed as toothed belt pulleys. With this known device, the printing cylinder carriage and the anilox roller carriage of a flexographic printing machine can be moved relative to the machine frame in such a way that the anilox roller carriage moves relative to the frame at twice the speed of the printing cylinder carriage. As a result, a pressure cylinder change can be carried out in a simple manner, the rollers assuming a position relative to one another when the rollers are set up in the printing operation the impression cylinder touches the impression cylinder and the anilox roller contacts the impression cylinder. The known device is relatively complex both in terms of its structure and its control.

Aufgabe der Erfindung ist es daher, eine einfachere Vorrichtung der eingangs angegebenen Art zu schaffen, die sowohl in ihrer Konstruktion als auch ihrer Steuerung weniger aufwendig ist.The object of the invention is therefore to provide a simpler device of the type specified, which is less complex both in its construction and in its control.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der eingangs angegebenen Art dadurch gelöst, daß eine Spindel mit zwei Gewindeabschnitten mit Links- und Rechtsgewinden gleicher Steigung versehen und mit ihrem vorderen Endbereich drehbar, aber in axialer Richtung unverschieblich in dem vorderen Schlitten gelagert ist und daß der erste Gewindeabschnitt in eine an der Schlittenführung oder einem Gestell gehalterte erste Spindelmutter und der zweite Gewindeabschnitt zwischen dem ersten Gewindeabschnitt und dem vorderen Schlitten in eine an dem hinteren Schlitten befestigte zweite Spindelmutter eingeschraubt ist.According to the invention, this object is achieved in a device of the type mentioned above in that a spindle is provided with two threaded sections with left and right-hand threads of the same pitch and is rotatable with its front end region, but is immovably mounted in the front carriage in the axial direction, and in that the first The threaded section is screwed into a first spindle nut held on the slide guide or a frame, and the second threaded section between the first threaded section and the front slide is screwed into a second spindle nut fastened to the rear slide.

Wird die erfindungsgemäße Vorrichtung als Spindelantrieb für den oder die Druckzylinderschlitten und Rasterwalzenschlitten einer Flexodruckmaschine benutzt, lassen sich die Schlitten derart verfahren, daß sich der Rasterwalzenschlitten mit der doppelten Geschwindigkeit des Druckwalzenschlittens bewegt. Die Schlitten lassen sich somit schnell und einfach in Stellungen verfahren, in denen der Druckzylinder gegen einen anderen Druckzylinder auch unterschiedlichen Formats ausgetauscht werden kann. Zweckmäßigerweise sind die Schlitten in einer gemeinsamen Schlittenführung hintereinander geführt. Die erfindungsgemäße Vorrichtung kann aber auch zum Verfahren von Schlitten verwendet werden, von denen ein erster in einer gestellfesten Schlittenführung und der andere Schlitten in einer Schlittenführung des ersten Schlittens geführt ist.If the device according to the invention is used as a spindle drive for the printing cylinder carriage or anilox roller carriage of a flexographic printing machine, the carriage can be moved in such a way that the anilox roller carriage moves at twice the speed of the printing roller carriage. The slides can thus be moved quickly and easily into positions in which the printing cylinder can be exchanged for another printing cylinder of different formats. The slides are expediently guided one behind the other in a common slide guide. However, the device according to the invention can also be used for moving slides, the first of which is in a sled guide fixed to the frame and the other sled in a sled guide of the first sled is led.

Mit besonderem Vorteil läßt sich die erfindungsgemäße Vorrichtung bei sog. Vorsatzdruckwerken verwenden, also für Druckwerke, die beispielsweise einer Papiersackherstellungsanlage vorgeschaltet sind und die zu Papiersäcken zu verarbeitende Papierbahnen mit einem Einfarbendruck oder einem mehrfarbigen Druck versehen. An ein derartiges Vorsatzdruckwerk sind nur geringere Anforderungen hinsichtlich der Präzision zu stellen, so daß die erfindungsgemäße Vorrichtung mit besonderem Vorteil eingesetzt werden kann.The device according to the invention can be used with particular advantage in so-called attachment printing units, that is to say for printing units which, for example, are connected upstream of a paper bag production system and which provide the paper webs to be processed into paper bags with a single-color print or a multi-color print. Such a front printing unit only has to meet lower requirements with regard to precision, so that the device according to the invention can be used with particular advantage.

Nach einer bevorzugten Ausführungsform ist vorgesehen, daß die erste Spindelmutter drehbar, aber axial unverschieblich in der Schlittenführung gelagert und mit einem Zahnrad oder einer verzahnten Scheibe versehen ist, die über einen Antrieb verdrehbar ist. Erfolgt nach dieser Ausführungsform der Antrieb der Spindel nicht durch Verdrehen der Spindel selbst, sondern durch Verdrehen der ersten Spindelmutter, werden die beiden Schlitten, bzw. der Druckzylinderschlitten der Rasterwalzenschlitten, gemeinsam verschoben, ohne relativ zueinander eine Bewegung auszuführen. Auf diese Weise können im Druckbetrieb die Walzen an den Gegendruckzylinder angestellt und von diesem wegbewegt werden.According to a preferred embodiment it is provided that the first spindle nut is rotatably but axially immovably mounted in the slide guide and is provided with a toothed wheel or a toothed disk which can be rotated via a drive. If, according to this embodiment, the spindle is not driven by rotating the spindle itself, but rather by rotating the first spindle nut, the two carriages, or the printing cylinder carriage of the anilox roller carriages, are moved together without executing a movement relative to one another. In this way, the rollers can be placed against the impression cylinder and moved away from it in the printing operation.

Zweckmäßigerweise besteht der Antrieb aus einer eine Zahnriemenscheibe tragenden Welle, wobei die Zahnriemenscheibe mit der verzahnten Scheibe durch einen endlosen Zahnriementrieb in Antriebsverbindung steht.The drive expediently consists of a shaft carrying a toothed belt pulley, the toothed belt pulley being in drive connection with the toothed disk by means of an endless toothed belt drive.

Die Spindel und die Welle können mit besonderen Antrieben, beispielsweise Getriebemotoren, versehen sein. Nach einer einfachen Ausführungsform ist vorgesehen, daß die Antriebseinrichtungen aus Handrädern bestehen.The spindle and the shaft can be provided with special drives, for example geared motors. According to a simple embodiment, it is provided that the drive devices consist of handwheels.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert, in deren einziger Figur eine Seitenansicht der auf Konsolen des Gestells einer Flexodruckmaschine verschieblich gelagerten Druck- und Rasterwalzenschlitten, teilweise im Schnitt, schematisch dargestellt ist.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing, in the single figure of which a schematic side view of the printing and anilox roller carriages slidably mounted on consoles of the frame of a flexographic printing press is shown, partly in section.

In einem Lagerbock 1 des nicht näher dargestellten Druckmaschinengestells ist in üblicher Weise der Gegendruckzylinder 2 gelagert. Der Gegendruckzylinder 2 ist in der dargestellten Weise von einer zu bedruckenden Papierbahn teilweise umschlungen, die über die im Druckmaschinengestell gelagerten Zuführungs- und Abführungswalzen 4, 5 läuft.The counter-pressure cylinder 2 is mounted in a bearing block 1 of the printing press frame, which is not shown in detail. The impression cylinder 2 is partially wrapped in the manner shown by a paper web to be printed, which runs over the feed and discharge rollers 4, 5 mounted in the press frame.

Das Druckmaschinengestell ist mit nach links und nach rechts auskragenden Konsolen 6, 7 versehen, die jeweils mit einer Schlittenführung versehen sind, auf denen die die Druckzylinder und Farbauftragszylinder lagernden Schlitten verfahrbar sind.The printing press frame is provided with brackets 6, 7 projecting to the left and to the right, each of which is provided with a slide guide on which the slides supporting the printing cylinders and inking cylinders can be moved.

Die Art des Antriebs der den Druckzylinder und den Farbauftragszylinder lagernden Schlitten wird nun anhand der rechten Konsole 6 näher erläutert.The type of drive of the carriage supporting the printing cylinder and the inking cylinder will now be explained in more detail using the right console 6.

In dem als verfahrbaren Schlitten ausgebildeten vorderen Lagerbock 8 ist der Klischee- oder Druckzylinder 9 in üblicher Weise gelagert. In einer Bohrung des Lagerbocks 8 ist das vordere Ende der Spindel 10 über Wälzlager 11 drehbar, aber axial unverschieblich, gelagert. Die Spindel 10 ist im Abstand voneinander mit Gewindeabschnitten 12, 13 mit Links- und Rechtsgewinde mit gleicher Steigung versehen. Der äußere Gewindeabschnitt 13 ist in eine Spindelmutter 14 eingeschraubt, die frei drehbar, aber axial unverschieblich, über Wälzlager 15 in einem aufragenden, fest mit der Konsole 6 verbundenen Träger (20) gelagert ist. Der Gewindeabschnitt 12, der sich auf der Spindel 10 zwischen dem Gewindeabschnitt 13 und dem vorderen Ende befindet, ist in eine Spindelmutter 16 eingeschraubt, die fest mit dem als Schlitten ausgebildeten Lagerbock 17 verbunden ist, in dem in üblicher Weise der Farbauftrags- oder Rasterwalzenzylinder 18 gelagert ist. Die Gewindebohrung der Spindelmutter 16 fluchtet mit einer Bohrung 19 des Lagerbocks 17, die die Spindel 10 durchsetzt.The cliché or printing cylinder 9 is mounted in the usual manner in the front bearing block 8, which is designed as a movable carriage. In a bore of the bearing block 8, the front end of the spindle 10 can be rotated via roller bearings 11, but is axially immovable. The spindle 10 is provided at a distance from one another with threaded sections 12, 13 with left and right hand threads with the same pitch. The outer threaded section 13 is screwed into a spindle nut 14, which is freely rotatable, but axially immovable, via roller bearings 15 in a towering carrier (20) firmly connected to the bracket 6. The threaded portion 12 located on the spindle 10 between the threaded portion 13 and the front end is screwed into a spindle nut 16 which is fixedly connected to the bearing block 17 designed as a slide, in which the inking or anilox roller cylinder 18 is mounted in the usual way. The threaded bore of the spindle nut 16 is aligned with a bore 19 of the bearing block 17 which passes through the spindle 10.

Die in dem aufragenden Träger 20 frei drehbar gelagerte Spindelmutter 14 ist an ihrem äußeren Umfang mit einer Zahnriemenscheibe 21 versehen. In dem aufragenden Träger ist eine Welle 22 drehbar gelagert, die in der dargestellten Weise eine Zahnriemenscheibe 23 trägt. Über die Zahnriemenscheiben 21, 23 läuft der endlose Zahnriementrieb 24. Auf die äußeren Enden der Spindel 10 und der Welle 22 sind Handräder bildende Knaufe 25, 26 aufgesetzt, über die sich die Spindel 10 bzw. die Welle 22 verdrehen lassen.The spindle nut 14, which is freely rotatably mounted in the upstanding carrier 20, is provided on its outer circumference with a toothed belt pulley 21. A shaft 22, which carries a toothed belt pulley 23 in the manner shown, is rotatably mounted in the upstanding carrier. The endless toothed belt drive 24 runs over the toothed belt pulleys 21, 23. Handwheels forming knobs 25, 26 are placed on the outer ends of the spindle 10 and the shaft 22, via which the spindle 10 and the shaft 22 can be rotated.

Der Zahnriementrieb ist derart selbsthemmend, daß er die Spindelmutter 14 undrehbar hält, wenn die Welle 22 nicht über den Knauf 26 verdreht wird.The toothed belt drive is so self-locking that it keeps the spindle nut 14 non-rotatable when the shaft 22 is not rotated via the knob 26.

Wird die Spindel 10 über den Handknauf 25 gedreht, lassen sich der Druckzylinder 9 an den Gegendruckzylinder 2 und der Farbauftragszylinder 18 an den Druckzylinder 9 anstellen. Der Antrieb ist derart aufeinander abgestimmt, daß der Farbauftragszylinder 18 den Druckzylinder 9 gerade dann berührt, wenn der Druckzylinder 9 an den Gegendruckzylinder 2 angestellt ist.If the spindle 10 is rotated via the hand knob 25, the pressure cylinder 9 can be turned on the impression cylinder 2 and the inking cylinder 18 on the pressure cylinder 9. The drive is coordinated with one another in such a way that the inking cylinder 18 touches the printing cylinder 9 just when the printing cylinder 9 is in contact with the impression cylinder 2.

Wird die Spindel 10 über den Knauf 25 in der Gegenrichtung gedreht, werden sowohl der Druckzylinder 9 von dem Gegendruckzylinder 1 und der Farbauftragszylinder 18 von dem Druckzylinder 9 abgefahren und zwar jeweils mit gleicher Geschwindigkeit bzw. um gleiche Strecken, weil sich relativ zu dem Gegendruckzylinder 2 der Farbauftragszylinder 18 mit der doppelten Geschwindigkeit wie der Druckzylinder 9 bewegt.If the spindle 10 is turned in the opposite direction via the knob 25, both the impression cylinder 9 are moved by the impression cylinder 1 and the inking cylinder 18 by the impression cylinder 9, in each case at the same speed or by the same distance, because relative to the impression cylinder 2 the inking cylinder 18 moves at twice the speed of the printing cylinder 9.

Wird bei stillstehender Spindel die Welle 22 über den Knauf 26 gedreht, wird über den Zahnriementrieb die Spindelmutter 14 gedreht, so daß die Böcke 8, 17 des Druckzylinders 9 und des Farbauftragszylinders 18 gemeinsam ohne Relativbewegung zueinander verfahren werden können.If the shaft 22 is rotated via the knob 26 when the spindle is at a standstill, the spindle nut 14 is rotated via the toothed belt drive, so that the jacks 8, 17 of the printing cylinder 9 and the inking cylinder 18 can be moved together without relative movement to one another.

Auf der links hin auskragenden Druckmaschinenkonsole 7 sind der Druckzylinder 9' und der Farbauftragszylinder 18' in ihren ebenfalls als Schlitten ausgebildeten Lagerböcken in entsprechender Weise verfahrbar. Die Antriebe der den Druckzylinder und den Farbauftragszylinder lagernden Böcke sind in gleicher Weise ausgebildet, wie es anhand der rechten Konsole 6 beschrieben worden ist.The printing cylinder 9 'and the inking cylinder 18' can be moved in a corresponding manner in their bearing blocks, which are likewise designed as slides, on the printing machine console 7 which projects out to the left. The drives of the trestles supporting the printing cylinder and the inking cylinder are designed in the same way as has been described with reference to the right console 6.
