Description

Die Erfindung betrifft eine Lagerung für Druckwerkszylinder oder dergleichen mit einstellbarem Seitenregister gemäss Oberbegriff des Anspruchs 1.The invention relates to a bearing for printing unit cylinders or the like with an adjustable side register according to the preamble of claim 1.

Bei einer aus der DE-C 897107 bekannten Lagerung dieser Art ist der Zylinder auf einer durchgehenden Welle gelagert, mit der ein Aussenkonus fest verbunden ist, während der andere Aussenkonus auf einer auf die Welle aufschiebbaren Hülse angeordnet ist, die durch eine Schraubverbindung zum Festspannen des Zylinders in Richtung auf den anderen Aussenkonus spannbar ist. Die Welle ist einseitig drehbar, aber axial unverschieblich in einer mit einem Handrad versehenen Hülse gelagert, die in einer im Gestell axial unverschieblichen Hülse eingeschraubt ist. Da die Welle auf der gegenüberliegenden Seite axial verschieblich gelagert ist, lässt sich durch Verdrehen der Hülse über das Handrad das Seitenregister einstellen.In a known from DE-C 897107 storage of this type, the cylinder is mounted on a continuous shaft with which an outer cone is fixedly connected, while the other outer cone is arranged on a sleeve which can be pushed onto the shaft and which is tightened by a screw connection for tightening the Cylinder can be clamped in the direction of the other outer cone. The shaft can be rotated on one side, but is axially immovable in a sleeve provided with a handwheel, which is screwed into a sleeve that is axially immovable in the frame. Since the shaft is axially displaceable on the opposite side, the side register can be adjusted by turning the sleeve using the handwheel.

Bei der bekannten Vorrichtung ist nicht nur das Auswechseln des Zylinders umständlich, weil hierzu die gesamte Welle ausgebaut und nach Wechsel des Zylinders der neue Zylinder auf der Welle durch die spannbare Hülse festgelegt werden muss, sondern eine Einstellung des Seitenregisters durch Drehen des Handrades ist erst nach der Lösung einer Verklemmung der Hülsen miteinander möglich, die nach der Einstellung des Seitenregisters wieder miteinander zu verklemmen sind.In the known device, not only is the replacement of the cylinder cumbersome, because the entire shaft has to be removed and the new cylinder has to be fixed on the shaft by the tensionable sleeve after changing the cylinder, but an adjustment of the side register by turning the handwheel is only after the solution of a jamming of the sleeves possible with each other, which are to be jammed together again after setting the side register.

Aufgabe der Erfindung ist es, eine Lagerung der eingangs angegebenen Art zu schaffen, die einen schnellen und einfachen Wechsel der Zylinder gestattet und die die insbesondere nach einem Zylinderwechsel notwendige Einstellung des Seitenregisters in einfacher Weise bei einer hohen Einspannkraft des Zylinders ermöglicht.The object of the invention is to provide a bearing of the type specified at the outset, which allows the cylinders to be changed quickly and easily and which, in particular after a cylinder change, allows the side register to be set in a simple manner with a high clamping force of the cylinder.

Erfindungsgemäss wird diese Aufgabe durch die Merkmale des Kennzeichens des Anspruchs 1 gelöst. Die erfindungsgemässe Lagerung erlaubt einen schnellen und einfachen Wechsel der Zylinder einfach dadurch, dass der eine Wellenzapfen unmittelbar nach oder bei dem Zurückfahren der diesen belastenden Kolbenstange aus dem Innenkonus herausgezogen und der andere Wellenzapfen durch Betätigung des Drehantriebs durch den durch die miteinander verschraubten Hülsen geschaffenen Spindeltrieb nach Zurückziehen der entsprechenden Kolbenstange zurückgefahren wird. Der auf diese Weise freigegebene Zylinder lässt sich gegen einen anderen austauschen, in dessen Innenkonen die Aussenkonen der Wellenzapfen in entsprechend umgekehrter Weise wieder eingefahren werden.According to the invention, this object is achieved by the features of the characterizing part of claim 1. The storage according to the invention allows the cylinders to be changed quickly and easily simply by pulling one of the shaft journals out of the inner cone immediately after or when the piston rod loading them moves back and the other shaft journals by actuating the rotary drive through the spindle drive created by the screwed sleeves Retracting the corresponding piston rod is retracted. The cylinder released in this way can be exchanged for another, in the inner cones of which the outer cones of the shaft journals are retracted in a correspondingly reverse manner.

Zur Einstellung des Seitenregisters ist es lediglich erforderlich, den Drehantrieb der äusseren Hülse zu betätigen, so dass aufgrund des Spindeltriebes die gewünschte Axialverschiebung des Zylinders erfolgt. Diese Einstellung des Seitenregisters kann bei voller, von den Kolben-Zylinder-Einheiten erzeugter Spannkraft erfolgen, wenn die sich bei einer Axialverstellung gegensinnig in ihrem Volumen ändernden Zylinderkammern miteinander verbunden sind. Denn der Spindeltrieb braucht nur die Reibung zwischen den relativ zueinander bewegten Teilen und die durch die Verdrängung der Hydraulikflüssigkeit zwischen den Zylinderkammern bewirkten Widerstände zu überwinden. Eine unverschiebliche Einspannung des Zylinders wird dadurch bewirkt, dass die Verbindung zwischen den Zylinderkammern aufgehoben wird oder die äusseren Zylinderkammern an die Druckmittelquelle angeschlossen werden.To set the side register, it is only necessary to actuate the rotary drive of the outer sleeve, so that the desired axial displacement of the cylinder takes place due to the spindle drive. This setting of the side register can take place with full clamping force generated by the piston-cylinder units if the cylinder chambers which change in volume in opposite directions during an axial adjustment are connected to one another. This is because the spindle drive only needs to overcome the friction between the parts moving relative to one another and the resistances caused by the displacement of the hydraulic fluid between the cylinder chambers. An immovable clamping of the cylinder is brought about by the fact that the connection between the cylinder chambers is broken or the outer cylinder chambers are connected to the pressure medium source.

Zweckmässigerweise ist der dem in der Hülse gelagerten Wellenzapfen gegenüberliegende Wellenzapfen mit der mit diesem axial fluchtenden Kolbenstange drehbar verbunden, so dass dieser Wellenzapfen zugleich mit dem Einfahren der Kolbenstange zurückgezogen werden kann.The shaft journal opposite the shaft journal mounted in the sleeve is expediently rotatably connected to the axially aligned piston rod so that this shaft journal can be retracted at the same time as the piston rod is retracted.

Die den Wellenzapfen lagernde Hülse kann mit einem radialen Hebel versehen sein, dessen Ende in einer axial verlaufenden gestellfesten Führungsnut geführt ist.The sleeve supporting the shaft journal can be provided with a radial lever, the end of which is guided in an axially extending guide groove fixed to the frame.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die mit der den Wellenzapfen lagernden Hülse verschraubte Hülse über einen Getriebemotor verdrehbar ist. Das Seitenregister ist sodann in einfacher Weise nur durch Betätigung des Getriebemotors, beispielsweise durch Knopfdruck, einstellbar, wobei sodann sogleich durch ein Steuerventil die entsprechenden Zylinderseiten der Kolben-Zylinder-Einheiten in einer eine Axialverschiebung ermöglichenden Weise miteinander verbunden werden.In a further embodiment of the invention it is provided that the sleeve screwed to the sleeve supporting the shaft journal can be rotated via a geared motor. The side register can then be adjusted in a simple manner only by actuating the geared motor, for example by pressing a button, the corresponding cylinder sides of the piston-cylinder units then being connected to one another in a manner which enables axial displacement by means of a control valve.

Zweckmässigerweise ist zur Einstellung des Seitenregisters der in der Hülse gelagerte Wellenzapfen im axialen Abstand mit das Seitenregister anzeigenden Markierungen versehen, die durch Fühler abtastbar sind.For setting the side register, the shaft journal mounted in the sleeve is expediently provided with markings which indicate the side register at an axial distance and can be scanned by sensors.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die den Wellenzapfen lagernde Hülse unmittelbar oder über einen zapfenförmigen Fortsatz in den Boden der im Gestell gelagerten Hülse eingeschraubt ist und dass sich die Kolbenstange der Kolben-Zylinder-Einheit auf die Hülse oder den mit dieser verbundenen Fortsatz abstützt.In a further embodiment of the invention it is provided that the sleeve supporting the shaft journal is screwed into the bottom of the sleeve mounted in the frame directly or via a journal-shaped extension and that the piston rod of the piston-cylinder unit is placed on the sleeve or the extension connected to it supports.

An embodiment of the invention is explained below with reference to the drawing. In this shows
  • 1 shows a longitudinal section through the mounting of a printing couple cylinder,

Ein Zylinder 1, beispielsweise ein Druckwerkszylinder, weist beidseitig konzentrisch zu seiner Mittelachse Innenkonen 2, 3 auf, in die die Aussenkonen 4, 5 von zentrierenden und drehbar gelagerten Wellenzapfen (Pinolen) 6, 7 eingreifen, die den Zylinder 1 in der Arbeitsstellung halten. Der Aussenkonus 4 ist mit einer Feder 8, die in eine in den Innenkonus 2 eingefräste Nut eingreift, mit dem Zylinder 1 formschlüssig verbunden. Die Wellenzapfen 6, 7 sind in Lagerbuchsen 10, 11 drehbar gelagert, die mit dem Gestell 12 fest verbunden sind. Die Lagerbuchsen 10, 11 sind derart ausgebildet, dass die Wellenzapfen 6, 7 über die diese lagernden Wälzlager in diesen in axialer Richtung verschieblich sind.A cylinder 1, for example a printing unit cylinder, has on both sides concentric to its central axis inner cones 2, 3, in which the outer cones 4, 5 of centering and rotatably mounted shaft journals (sleeves) 6, 7 engage, which hold the cylinder 1 in the working position. The outer cone 4 is positively connected to the cylinder 1 by a spring 8 which engages in a groove milled into the inner cone 2. The shaft journals 6, 7 are rotatably mounted in bearing bushes 10, 11 which are firmly connected to the frame 12. The bearing bushes 10, 11 are designed in such a way that the shaft journals 6, 7 can be displaced in the axial direction via the roller bearings that support them.

Der Wellenzapfen 7 ist mit der Kolbenstange eines gestellfesten Hydraulikzylinders 13 drehbar, aber axial unverschieblich verbunden.The shaft journal 7 is rotatably connected to the piston rod of a hydraulic cylinder 13 fixed to the frame, but is axially immovable.

Der Wellenzapfen 6 ist in einer gestellfesten Lagerbuchse 14 drehbar und ebenfalls axial unverschieblich gelagert. Auf dem Wellenzapfen 6 ist ein Zahnrad 16 aufgekeilt, das mit einem Zahnrad 17 kämmt. Das Zahnrad 17 sitzt auf einer nicht dargestellten Welle, die mit dem Hauptantrieb in Antriebsverbindung steht.The shaft journal 6 is rotatable in a bearing bush 14 fixed to the frame and is also axially immovable. A gearwheel 16, which meshes with a gearwheel 17, is wedged on the shaft journal 6. The gear 17 sits on a shaft, not shown, which is in drive connection with the main drive.

Der Wellenzapfen 6 ist in der Hülse 18 drehbar, aber axial unverschieblich gelagert. Die Hülse 18 ist axial verschieblich in der diese einfassenden Hülse 19 geführt. Mit der Hülse 18 ist der radiale Hebel 20 verbunden, dessen Ende in der Nut einer gestellfesten Führungsbahn 21 geführt ist, so dass die Hülse 18 keine Drehung, sondern lediglich eine Bewegung in axialer Richtung ausführen kann. Die Länge 22 der Führungsbahn 21 ist so bemessen, dass der Hebel 20 während seiner gesamten axialen Verschiebung mit der Führungsbahn 21 im Eingriff bleibt. Das Zahnrad 17 ist so breit, dass es immer mit dem Zahnrad 16 in Eingriff bleibt. Mit der Führungsbuchse 19 ist ein Tellerrad 23 fest verbunden, das mit einem Kegelrad 24 kämmt, dessen Welle gestellfest gelagert und mit einem nicht dargestellten Getriebemotor verbunden ist. Die Hülse 18 ist endseitig mit einem Zapfen 18.1 verbunden, dessen Mantelfläche mit einem Gewinde versehen ist, das in eine Gewindebohrung des Bodens der Führungshülse 19 eingeschraubt ist. Durch Drehen des Kegelrades 24 und damit der Führungshülse 19 wird die Hülse 18 ein- oder herausgeschraubt, so dass der mit dieser verbundene Wellenzapfen 6 hin- oder hergeschoben wird.The shaft journal 6 is rotatable in the sleeve 18, but is axially immovable. The sleeve 18 is guided axially displaceably in the sleeve 19 enclosing this. The radial lever 20 is connected to the sleeve 18, the end of which is guided in the groove of a guide track 21 which is fixed to the frame, so that the sleeve 18 cannot carry out any rotation, but rather only a movement in the axial direction. The length 22 of the guideway 21 is dimensioned such that the lever 20 remains in engagement with the guideway 21 during its entire axial displacement. The gear 17 is so wide that it always remains in engagement with the gear 16. With the guide bush 19, a ring gear 23 is firmly connected, which meshes with a bevel gear 24, the shaft of which is fixed to the frame and is connected to a geared motor (not shown). The sleeve 18 is connected at the end to a pin 18.1, the outer surface of which is provided with a thread which is screwed into a threaded bore in the bottom of the guide sleeve 19. By turning the bevel gear 24 and thus the guide sleeve 19, the sleeve 18 is screwed in or out, so that the shaft journal 6 connected to it is pushed back and forth.

Durch den Getriebemotor kann der Wellenzapfen 6 gänzlich aus dem Zylinder 1 zurückgezogen oder gegen diesen gespannt werden. Die Spannung des Zylinders 1 erfolgt von rechts über den Wellenzapfen 7 durch den Hydraulikzylinder 13.The shaft journal 6 can be withdrawn entirely from the cylinder 1 or tensioned against the latter by the geared motor. The cylinder 1 is tensioned from the right via the shaft journal 7 by the hydraulic cylinder 13.

Damit der Zylinder 13 nicht mit voller Kraft auf das Gewinde des Zapfens 18.1 wirkt, ist ein weiterer Hydraulikzylinder 26 vorgesehen, dessen Kolbenstange auf der Stirnfläche des Zapfens 18.1 abgestützt ist.So that the cylinder 13 does not act with full force on the thread of the pin 18.1, a further hydraulic cylinder 26 is provided, the piston rod of which is supported on the end face of the pin 18.1.

In Fig. 4 ist der Hydraulikschaltplan für die beiden Hydraulikzylinder 13, 26 schematisch dargestellt, die durch ein Vier-Wege-Ventil 27 einmal gemeinsam aufeinander zu und voneinander weg gesteuert und von der Druckmittelquelle getrennt werden können.4 schematically shows the hydraulic circuit diagram for the two hydraulic cylinders 13, 26, which can be controlled together towards and away from one another by a four-way valve 27 and separated from the pressure medium source.

Durch die dargestellte Verbindung der Zylinderkammern wird das Gewinde auf dem Zapfen 18.1 bzw. in der Hülse 19 vollständig entlastet und die von dem Getriebemotor über das Kegelrad 24 aufzubringende Arbeit beschränkt sich lediglich auf die Überwindung der Reibung in den Führungen und des Widerstandes infolge der Verdrängung der Hydraulikflüssigkeit.Through the connection of the cylinder chambers shown, the thread on the pin 18.1 or in the sleeve 19 is completely relieved and the work to be performed by the geared motor via the bevel gear 24 is limited only to overcoming the friction in the guides and the resistance as a result of the displacement of the Hydraulic fluid.

Zum Herausnehmen des Zylinders 1 werden die Hydraulikzylinder 13, 26 betätigt und die Kolbenstangen zurückgefahren, wodurch der Wellenzapfen 7 nach rechts verschoben wird. Der Wellenzapfen 6 wird durch Drehen des Kegelrades 24 nach links verschoben, bis der Zylinder freikommt.To remove the cylinder 1, the hydraulic cylinders 13, 26 are actuated and the piston rods are retracted, as a result of which the shaft journal 7 is shifted to the right. The shaft journal 6 is shifted to the left by turning the bevel gear 24 until the cylinder is released.

Auf dem Wellenzapfen 6 ist eine Hülse 28 mit drei vorstehenden Schaltringen 29, 30, 31 befestigt, die durch Fühler (Initiatoren) 32, 33 abgefastet werden können. Diese dienen dazu, dass die richtige Seitenregisterstellung des Zylinders erreicht wird. Die Mittelstellung wird durch den Initiator 32 gemeldet, wenn der Wellenzapfen- 6 nach rechts verschoben wird. Die maximal zulässigen Verschiebungen nach rechts und links werden durch den Initiator 33 gemeldet, wenn die Schaltringe 30 bzw. 31 in seinen Wirkbereich kommen.On the shaft journal 6, a sleeve 28 is fastened with three protruding switching rings 29, 30, 31, which can be chamfered by sensors (initiators) 32, 33. These are used to ensure that the correct side register position of the cylinder is achieved. The middle position is reported by the initiator 32 when the shaft journal 6 is shifted to the right. The maximum permissible displacements to the right and left are reported by the initiator 33 when the switching rings 30 and 31 come into their effective range.
