Abstract

The holding device for hollow-cylinder printing formes comprises two adaptor rings (4) which are pressed into the free ends of the hollow cylinder (1) so as to form a seal and which are held under these circumstances in a latched condition by a spring-preloaded latch mechanism (5, 6). Because of the centred adaptor rings (4) a bulky and expensive mounting by means of plug-in spindle cone pieces and pressure pieces is unnecessary.

Description

Die Erfindung betrifft eine Haltevorrichtung für als Hohlzylinder ausgeführte Druckformen bei der Formherstellung, insbesondere im Galvanikbereich.The invention relates to a holding device for printing forms designed as hollow cylinders in mold production, in particular in the electroplating sector.

Hohlzylinder-Druckformen werden vor allem im Verpackungsdruck benutzt. Um solche Hohlzylinder bei der Formherstellung, insbesondere im Galvanikbereich, bearbeiten zu können, ist es notwendig, die Zylinder endseitig so zu adaptieren, daß in den Galvanikanlagen sowohl die erforderlichen hohen Stromdichten als auch ein ausreichendes Drehmoment übertragen werden können. Außerdem ist die Dichtheit zu gewährleisten, d.h. es darf kein Elektrolyt in den Innenraum der Hohlzylinder-Druckform gelangen.Hollow cylinder printing forms are mainly used in packaging printing. In order to be able to process such hollow cylinders in mold production, particularly in the electroplating sector, it is necessary to adapt the ends of the cylinders so that both the required high current densities and sufficient torque can be transmitted in the electroplating systems. In addition, the tightness must be guaranteed, ie there must be no electrolyte in the interior of the hollow cylinder printing form reach.

Bisher werden Hohlzylinderdruckformen überwiegend durch Spannfutter gehalten, die die Hohlzylinder mittels einer Hydraulik an den Stirnseiten verspannen (JP-59-16 753, JP-61-26 37 54). Zur Zentrierung und formschlüssigen Halterung sind die Hohlzylinder dazu mit konischen Bohrungen an den Stirnseiten versehen. Üblicherweise drückt dabei eine Ringdichtung gegen die Zylinderstirnwand und dichtet so den Spalt zwischen Haltevorrichtung und Hohlzylinder ab.So far, hollow cylinder printing forms have been held mainly by chucks which clamp the hollow cylinders on the end faces by means of hydraulics (JP-59-16 753, JP-61-26 37 54). For centering and positive locking, the hollow cylinders are provided with conical bores on the end faces. Usually, an annular seal presses against the cylinder end wall and thus seals the gap between the holding device and the hollow cylinder.

Diese bekannten Haltevorrichtungen benötigen sehr aufwendige Hydraulikeinrichtungen, was die Handhabung und Adaptierung der Hohlzylinder bei der Galvanisierung enorm erschwert.These known holding devices require very complex hydraulic devices, which enormously complicates the handling and adaptation of the hollow cylinders during the galvanizing.

Der Erfindung liegt die Aufgabe zugrunde, eine räumlich kleine, technisch wenig aufwendige Haltevorrichtung für Hohlzylinder der genannten Art und zu dem erläuterten Zweck zu schaffen.The invention has for its object to provide a spatially small, technically inexpensive holding device for hollow cylinders of the type mentioned and for the purpose explained.

Eine Haltevorrichtung für Hohlzylinder-Druckformen nach dem Oberbegriff des Patentanspruchs 1 ist erfindungsgemäß gekennzeichnet durch je eine an dem jeweils der Hohlzylinderinnenseite zugekehrten Ende eines Adapterrings angesetzte Klinkenvorrichtung mit mehreren sternförmig angeordneten, federvorbelasteten Klinken, die bei in das jeweilige Hohlzylinderende eingedrücktem Adapterring die innenseitige Stirnfläche einer in das jeweilige stirnseitige Hohlzylinderende eingesetzten und mit der Hohlzylinderinnenwand fest verbundenen Ronde hintergreifen und den Adapterring gegen Herausfallen sichern.A holding device for hollow cylinder printing plates according to the preamble of claim 1 is characterized according to the invention by a ratchet device attached to the end of an adapter ring facing the inside of the hollow cylinder with a plurality of star-shaped, spring-loaded pawls which, when the adapter ring is pressed into the respective hollow cylinder end, the inside end face of a insert the respective end of the hollow cylinder end, which is firmly connected to the inner wall of the hollow cylinder, and secure the adapter ring against falling out.

Die räumlich kleinen Adapterstücke, die auf den beiden Stirnseiten in die konische Bohrung der an der Zylinderinnenwand fixierten Ronden eingesteckt werden, sind durch den Klinkenmechanismus verspannt. Dadurch wird verhindert, daß die Adapter nach dem Eindrücken in die konische Rondenbohrung wieder herausfallen. Die außenseitig an die Adapterringe angesetzten Flanschschultern mit gegen die Zylinderstirnfläche drückender Abdichtung gewährleisten eine gewisse zusätzliche axiale Verspannung, aber auch eine sichere Abdichtung gegen das Eindringen von Elektrolyt in den Hohlzylinderinnenraum.The spatially small adapter pieces, which are inserted into the conical bore of the discs fixed to the inside of the cylinder on both ends, are clamped by the latch mechanism. This prevents the adapters from falling out again after being pressed into the conical round bore. The outside of the adapter rings attached flange shoulders with a seal pressing against the cylinder face ensure a certain additional axial bracing, but also a secure seal against the penetration of electrolyte into the hollow cylinder interior.

Die sternförmig angeordneten, federvorbelasteten Klinken verspreizen sich auf der innenseitigen Stirnringfläche der jeweiligen Ronde. Um den fest verspannten Adapterring am Ende eines Arbeitsprozesses abziehen zu können, wird in die axiale Mittelbohrung des jeweiligen Adapterrings ein Stift eingeführt, durch welche die Klinken entgegen der Kraft der Federvorbelastung entriegelt werden. Der Adapterring läßt sich dann leicht entnehmen.The star-shaped, spring-loaded pawls spread out on the inside front ring surface of the respective blank. In order to be able to pull off the firmly clamped adapter ring at the end of a working process, a pin is inserted into the axial central bore of the respective adapter ring, by means of which the pawls are unlocked against the force of the spring preload. The adapter ring can then be easily removed.

Die erfindungsgemäßen Adapterteile bieten in Verbindung mit einem entsprechend angepaßten Krantransportsystem bei der Handhabung der Hohlzylinderdruckformen in einer Galvanikanlage zusätzliche Vorteile. So lassen sich die Hohlzylinder mittels einer Krantraverse, die über Klemmbacken formschlüssig den Hohlzylinder ergreift, sicher transportieren. Über in der Galvanikanlage innerhalb von axialverschleblichen Dichtrohren, die das Eindringen von Elektrolyt verhindern, vorhandene Pinolen, läßt sich der notwendige Strom und das Drehmoment zum Rotieren der Hohlzylinder in der Galvanikanlage gewährleisten.The adapter parts according to the invention offer additional advantages in connection with a correspondingly adapted crane transport system when handling the hollow cylinder printing plates in a galvanic system. In this way, the hollow cylinders can be safely transported by means of a crane traverse, which grips the hollow cylinder with a form fit. The necessary current and torque for rotating the hollow cylinders in the electroplating system can be ensured by means of quills in the electroplating system within axially displaceable sealing tubes which prevent the penetration of electrolyte.

Die linksseitige Darstellung der Fig. 1 läßt ein stirnseitiges Ende einer Hohlzylinder-Druckform 1(im folgenden nur als Hohlzylinder bezeichnet) erkennen, in das eine als Ronde 2 bezeichneter Ring mit konischer Innenbohrung eingesetzt ist. Für die erfindungsgemäße Haltevorrichtung wesentlich ist ein Adapterring 4, der in die Axialbohrung der Ronde 2 eingedrückt wird und dabei, wie die Fig. 2 (links) erkennen läßt, aufgrund eines konischen Axialansatzes form- und kraftschlüssig in Eingriffmit der konischen Innenbohrung der Ronde 2 gelangt.The left-hand representation of FIG. 1 shows an end face of a hollow cylinder printing form 1 (hereinafter referred to only as a hollow cylinder), into which a ring, called a round blank 2, with a conical inner bore is inserted. Essential for the holding device according to the invention is an adapter ring 4 which is pressed into the axial bore of the round blank 2 and, as can be seen in FIG. 2 (left), comes into positive and non-positive engagement with the conical inner bore of the round blank 2 due to a conical axial approach .

Der Adapterring 4 ist auf der dem Inneren des Hohlzylinder 1 zuzukehrenden Seite mit einem Haltering 9 verbunden, dessen Durchmesser geringfügig kleiner ist als der innenseitige Enddurchmesser der Ronde 2. Der Haltering 9 ist mit mehreren, im dargestellten Beispiel 3, jeweils um 120° gegeneinander versetzten Axialschlitzen versehen, die zur Aufnahme jeweils einer Klinke 5 dienen, welche in der mittleren Darstellung der Fig. 1 ersichtlichen Weise durch eine Feder 6 nach oben (außen) vorgespannt ist.The adapter ring 4 is connected on the side facing the interior of the hollow cylinder 1 to a retaining ring 9, the diameter of which is slightly smaller than the inside end diameter of the round blank 2. The retaining ring 9 is offset from one another by 120 ° in the example 3 shown Provide axial slots, which each serve to receive a pawl 5, which is shown in the middle view of FIG. 1, biased upwards (outwards) by a spring 6.

Sobald der Adapterring 4 in die konische Rondenbohrung eingedrückt ist, rastet die federvorbelastete Klinke 5 hinter der innenseitigen Stirnfläche der Ronde 2 ein, wodurch der Adapterring 4 in Axialrichtung verspannt wird. Dabei drückt jetzt, wie der linke Teil der Fig. 2 erkennen läßt, die Ringdichtung 7 in der ringförmigen Flanschschulter 8 gegen die Stirnfläehe des Hohlzylinders 1.As soon as the adapter ring 4 is pressed into the conical round bore, the spring-loaded pawl 5 engages behind the inside end face of the round blank 2, whereby the adapter ring 4 is clamped in the axial direction. Now, as the left part of FIG. 2 shows, the ring seal 7 in the annular flange shoulder 8 presses against the end face of the hollow cylinder 1.

Sobald die Adapterringe 4 in die stirnseitigen Öffnungen des Hohlzylinders 1 eingedrückt sind (vgl. Fig. 3) läßt sich der Hohlzylinder 1 mittels einer Krantraverse 10 mit axialverschieblichen form- und kraftschlüssiger Klemmbacken 11 anheben, um die in Fig. 5 schematisch dargestellte Galvanikanlage überführt zu werden. In der Galvanikanlage werden vor der eigentlichen Bearbeitung durch Pinolen 12 gehaltene Abdichtrohre 13 angesetzt. Dabei greifen die Pinolen 12 in eine entsprechend angepaßte Axialbohrung 4b des Adapterrings 4 ein, so daß eine sichere Führung, Strom- und Drehkraftübertragung bei gleichzeitig vollständiger Abdichtung gewährleistet ist.As soon as the adapter rings 4 are pressed into the end openings of the hollow cylinder 1 (cf. will. In the electroplating system, sealing tubes 13 held by sleeves 12 are attached before the actual machining. The sleeves 12 engage in a correspondingly adapted axial bore 4b of the adapter ring 4, so that reliable guidance, transmission of current and torque is ensured with a complete seal at the same time.

Um nach beendeter galvanischer Bearbeitung die Adapterringe 4 zu entfernen, läßt sich mittels eines nicht dargestellten Stifts der federvorbelastete Klinkenmechanismus mit der Klinke 5 durch Einschieben des Stifts in die Bohrung 14 lösen, so daß die Adapterringe 4 für eine erneute, anderweitige Verwendung entnommen werden können.In order to remove the adapter rings 4 after the galvanic processing has been completed, the spring-loaded pawl mechanism with the pawl 5 can be released by inserting the pin into the bore 14 by means of a pin, not shown, so that the adapter rings 4 can be removed for another, different use.
