Der erfindungsgemässe schnellschliessende Stromzuführungs- und Antriebs-Adapter zur drehbaren Halterung von in galvanischen Anlagen zu behandelnden Druckzylindern ist gekennzeichnet

  • durch eine Stromaufnahmevorrichtung, insbesondere durch einen Stromaufnahmezylinder,
  • durch eine an der genannten Stromaufnahmevorrichtung beweglichen Stromzuführungsvorrichtung, insbesondere durch einen im Stromaufnahmezylinder leitend gleitenden Kreiszylinderkolben und einen daran befestigten Stromzuführungs-Rohrkörper, sowie
  • durch eine Aufnahme- und Arretierungsvorrichtung für den Druckzylinder bzw. für dessen Verlängerungsstück, insbesondere durch eine Rohrachse mit einem an ihrem Ende angebrachten und sie mit dem Stromaufnahmezylinder verbindenden Flansch bzw. durch eine entsprechende Massivachse, je mit Fixierungseinrichtungen für die Achsen.
The fast-closing power supply and drive adapter according to the invention for the rotatable mounting of pressure cylinders to be treated in galvanic systems is characterized
  • by a current absorption device, in particular by a current absorption cylinder,
  • by means of a current supply device movable on the current absorption device mentioned, in particular by a circular cylinder piston sliding in the current absorption cylinder and a current supply tube body fastened thereon, and
  • by a receiving and locking device for the pressure cylinder or for its extension piece, in particular by means of a tubular axis with a flange attached to its end and connecting it to the current receiving cylinder or by means of a corresponding solid axis, each with fixing devices for the axes.

Der Kreiszylinderkolben ist dabei hydraulisch und/oder pneumatisch und/oder mechanisch und/oder magnetisch im genannten Stromaufnahmezylinder längs-bewegbar.The circular cylinder piston can be moved longitudinally hydraulically and / or pneumatically and / or mechanically and / or magnetically in the current intake cylinder mentioned.

Wesentlich ist auch, dass der Stromaufnahmezylinder, der Kreiszylinderkolben und der Stromzuführungs-Rohrkörper aus einem den elektrischen Strom gut leitenden, metallischen Werkstoff bestehen und dass der genannte Stromzuführungs-Rohrkörper zur stromschlüssigen Verbindung mit dem entsprechenden, den elektrischen Strom leitenden Teil des Druckzylinders dient.It is also essential that the current intake cylinder, the circular cylinder piston and the current supply tube body consist of a metallic material that conducts the electrical current well and that the current supply tube body serves for the current-locking connection with the corresponding part of the pressure cylinder that conducts the electrical current.

Bevorzugterweise weist der genannte Stromzuführungs- und Antriebs-Adapter eine Rohrachse auf, welche auf der Seite des Druckzylinders einen Anschlagsring zur Führung des Stromzuführungs-Rohrkörpers und zur Arretierung des Kolbens hat. Weiter enthält in dieser Ausführungsform der Stromaufnahmezylinder auf der Seite des Druckzylinders einen Anschlagsring zur Führung des Stromzuführungs-Rohrkörpers und zur Arretierung des Kolbens.The power supply and drive adapter mentioned preferably has a tube axis which is on the side of the printing cylinder has a stop ring for guiding the power supply tube body and for locking the piston. Furthermore, in this embodiment, the current intake cylinder on the side of the pressure cylinder contains a stop ring for guiding the power supply tube body and for locking the piston.

Bei einer zweiten bevorzugten Ausführungsform des Stromzuführungs- und Antriebs-Adapter trägt die Massivachse am dem Druckzylinder entgegengesetzten Ende einen Flanschdeckel, welcher den Hubweg des kreiszylindrischen Kolbens auf der genannten Seite begrenzt. Auf der Massivachse ist ein lös- und verschiebbarer Führungsring zur Arretierung des Achsenzylinders befestigt, welcher Führungsring den Hubweg des kreiszylindrischen Kolbens auf der andern Seite begrenzt.In a second preferred embodiment of the power supply and drive adapter, the solid axis carries a flange cover at the end opposite the pressure cylinder, which limits the stroke of the circular cylindrical piston on the said side. A releasable and displaceable guide ring for locking the axle cylinder is fastened on the solid axis, which guide ring limits the stroke of the circular-cylindrical piston on the other side.

Weiter gilt, dass der Stomaufnahmezylinder am dem Druckzylinder zugewandten Ende einen inneren Anschlagring zwecks Sicherung des kreiszylindrischen Kolbens trägt und dass der Stromzuführungsrohrkörper am dem Druckzylinder zugewandten Ende einen Dichtring trägt, welcher mittels eines dehnbaren Faltenbalges mit einer auf dem entsprechenden Endteil des Stromaufnahmezylinders aufgebrachten Hülse verbunden ist. Der genannte Dichtring weist auf seiner freien Seite einen Kontaktring zwecks Sicherung des elektrischen Kontaktes zur Stirnseite des Druckzylinders auf, die genannte Seite ist gegebenenfalls mit einem entsprechenden Stromabnahme-Konus versehen.It also applies that the current receiving cylinder at the end facing the pressure cylinder carries an inner stop ring for securing the circular cylindrical piston and that the power supply tube body at the end facing the pressure cylinder carries a sealing ring which is connected by means of an expandable bellows to a sleeve attached to the corresponding end part of the current receiving cylinder .

Gewünschtenfalls liegt der Stromaufnahmezylinder in Form einer Antriebsvorrichtung zum Antrieb des Druckzylinders und/oder in Form eines Drehlagers zur Lagerung desselben vor.If desired, the power consumption cylinder is in the form of a drive device for driving the printing cylinder and / or in the form of a rotary bearing for supporting the same.

Der Gesamt-Stromzuführungs- und Antriebs-Adapter besteht aus zwei Stromzuführungs- und Antriebs-Adaptern gemäss einer der oben beschriebenen Ausführungsformen.The overall power supply and drive adapter consists of two power supply and drive adapters according to one of the embodiments described above.

Verwendet wird der Gesamt-Stromzuführungs- und Antriebs-Adapter so,

  • dass ein oder mehr als ein Druckzylinder verschiedener Ballenlängen, gegebenenfalls untereinander verbunden, anhand der Achsen bzw. Hilfsachsen darin positioniert und fixiert wird/werden,
  • dass anschliessend mittels Verschiebung der Kolben die Stromzuführungs-Rohrkörper soweit vor-verschoben werden, dass die Stirnfläche der genannten Rohrkörper beidseitig auf die stromführende Gegenseite des Druckzylinders auftreffen, worauf die Stromzuführungs-Rohrkörper in dieser Position gehalten werden, und

Die Erfindung wird nun anhand der beiliegenden drei Figuren allgemein und beispielhaft beschrieben.The invention will now be described in general and by way of example with reference to the three enclosed figures.

Der Druckzylinder 15 in Figur 1 hat die Achse 13. Diese ist technisch genügend sicher am erfindungsgemässen Stromzuführungs- und Antriebs-Adapter mit dem Gegenflansch 12 und dem Stromaufnahmezylinder 11 befestigt.The pressure cylinder 15 in Figure 1 has the axis 13. This is technical Sufficiently securely attached to the power supply and drive adapter according to the invention with the counter flange 12 and the current consumption cylinder 11.

Die Art der Befestigung bzw. Arretierung des Achsendes im/am Adapter wird weiter unten, anhand der bevorzugten Ausführungsformen detaillierter besprochen werden. Grundsätzlich ist hierzu jedoch zu sagen, dass eine relativ einfache Befestigung des Achsendes, z.B. mittels eines Einklink- oder Bajonett-Verschlusses an bzw. in der Rohrachse des Adapters, genügt. Dadurch, dass auf beiden Achsenden je ein Stromzuführungs-Rohrstück 16 an die Zylinderseitenwand gepresst wird, werden die beiden Adapter permanent vom Druckzylinder weggezogen, d.h. auf die Achse 13 wird ein Dauerzug ausgeübt.The type of fastening or locking of the axle end in / on the adapter will be discussed in more detail below on the basis of the preferred embodiments. Basically, however, it can be said that a relatively simple attachment of the axle end, e.g. by means of a latch or bayonet lock on or in the tube axis of the adapter. Due to the fact that a power supply pipe section 16 is pressed onto the cylinder side wall on both ends of the axis, the two adapters are permanently pulled away from the pressure cylinder, i.e. a permanent train is exerted on axis 13.

In der ersten der beiden bevorzugten Ausführungsformen wird die Achse 23 des Druckzylinders 25 durch die Achshülse 28 des Adapters hindurchgeführt und rechts, ausserhalb des Gegenflansches 22, arretiert, z.B. mittels eines lösbaren Bolzenverschlusses 22a.In the first of the two preferred embodiments, the axis 23 of the pressure cylinder 25 is passed through the axis sleeve 28 of the adapter and locked on the right, outside the counter flange 22, e.g. by means of a detachable bolt lock 22a.

Ueber der Achshülse 28 gleitet der Kreiszylinderkolben 24, an dessen linker Wand das Stromzuführungs-Rohrstück 26 befestigt ist. Beim Bewegen des genannten Kolbens nach links stösst der Frontring 21a desselben schliesslich an die Stirnseite des Druckzylinders 25; diese Seite kann durch den Strom gut leitende Konusstücke 25a besetzt sein.The circular cylinder piston 24, on the left wall of which the power supply tube piece 26 is fastened, slides over the axle sleeve 28. When the piston mentioned is moved to the left, the front ring 21a finally strikes the end face of the pressure cylinder 25; this side can be occupied by the cone pieces 25a which conduct well.

Das Gleiten des Kreiszylinderkolbens 24 wird hier pneumatisch bewirkt: Durch die Oeffnung 22b tritt das Druckfluid - bevorzugterweise trockene Druckluft - ein und bewegt den Zylinderkolben nach links bis zum Anschlag (des Stromzuführungs-Rohrstückes); in dieser Stellung wird die Stromzuführungs-Vorrichtung durch den aufrecht erhaltenen Druck gehalten; sie garantiert so die technisch gesicherte Stromzufuhr zum Druckzylinder. Beim Ausfahren des Stromzuführungs-Rohrstückes nach links wird der Balg 21b gedehnt; er ist sowohl am linken Ende des Stromaufnahmezylinders 21 wie auch am Frontring 21a befestigt und dient der Abschirmung des ausgefahrenen Stromzuführungs-Rohrstückes 26 vor Säuretröpfchen, Staub u.ä. Sobald der Adapter am Achsende fixiert und das Stromzuführungs-Rohrstück bis zum Anschlag ausgefahren sind, kann der Zylinder (der jetzt an beiden Achsenden einen solchen Adapter trägt) in das Bad gegeben werden. Dazu kann an jedem Adapter noch ein Rundlager 21f vorgesehen werden. Ebenso kann der Zylinder nun, gegebenenfalls über ein Antriebsrad 21g, um seine Achse gedreht werden. Auch ein Antrieb ohne spezielle Antriebsvorrichtung am Adapter ist möglich, nämlich die Lagerung des Adapters in/auf Haft-Antriebsrollen. Von den starr installierten Elektroden 21e, beispielsweise Kohleelektroden, wird der zur Beschichtung notwendige elektrische Strom auf den Stromaufnahmezylinder 21 gegeben. Von dort gelangt er über den Kreiszylinderkolben 24 zum Stromzuführungs-Rohrstück 26 und von dort schliesslich, gegebenenfalls über Stromzuführungskoni 25a, auf die Oberfläche des Druckzylinders.The sliding of the circular cylinder piston 24 is effected pneumatically here: through the opening 22b, the pressure fluid - preferably dry compressed air - enters and moves the cylinder piston to the left as far as it will go (of the power supply pipe section); in this position the power supply device is held by the pressure maintained; it guarantees the technically secure power supply to the printing cylinder. When the power supply pipe section is extended to the left, the bellows 21b is stretched; it is fastened to both the left end of the power take-up cylinder 21 and to the front ring 21a and serves to shield the extended power supply pipe section 26 against acid droplets, dust etc. As soon as the adapter is fixed to the axle end and the power supply pipe section is extended as far as it will go, the cylinder (which now carries such an adapter on both axle ends) can be placed in the bath. For this purpose, a circular bearing 21f can be provided on each adapter. Likewise, the cylinder can now be rotated about its axis, possibly via a drive wheel 21g. A drive without a special drive device on the adapter is also possible, namely the mounting of the adapter in / on adhesive drive rollers. From the rigidly installed electrodes 21e, for example carbon electrodes, the electrical current required for coating is applied to the current consumption cylinder 21. From there it reaches the power supply pipe section 26 via the circular cylinder piston 24 and from there finally, if necessary via power supply cones 25a, to the surface of the printing cylinder.

Eine in vielem der Darstellung in Figur 2 analoge, andere Ausführungsform des erfindungsgemässen Stromzuführungs- und Antriebs-Adapters ist in Figur 3 dargestellt. Die Zylinderachse 33 wird über die Achse 38 des Adapters gefahren und darauf einmal mittels des Anschlagringes 39a und mittels des Federringes 39c festgehalten. Die weiteren Bestandteile entsprechen denjenigen der Figur 2. Auch hier weisen der Stromaufnahmezylinder 31 links innen und die Adapterachse 38 links aussen je einen Anschlagring (39a, b) zwecks Sicherung des Kreiszylinderkolbens und zwecks Führung des Stromzuführungs-Rohrstückes 36 auf.A different embodiment of the power supply and drive adapter according to the invention, which is analogous to the illustration in FIG. 2, is shown in FIG. 3. The cylinder axis 33 is moved over the axis 38 of the adapter and held thereon once by means of the stop ring 39a and by means of the spring ring 39c. The other components correspond to those in FIG. 2. Here, too, the current intake cylinder 31 on the inside on the left and the adapter axis 38 on the outside on the left each have a stop ring (39a, b) for securing the circular cylinder piston and for guiding the power supply pipe section 36.

Bei der praktischen Verwendung des erfindungsgemässen Stromaufnahme- und Antriebs-Adapters werden erhebliche technische Fortschritte erzeugt:

  • eine schnelle und einfache Aufspindelung des Adapters,
  • ein technisch genügend gesicherter Stromkontakt,
  • wenig Einzelkomponenten (verglichen mit früher vielen Einzelstücken, durch deren Verschraubung solche Ansätze zusammenzustellen waren),
  • verbesserter Rundlauf des Druckzylinders aufgrund der Aufhebung der Durchbiegung (die Zylinderachse wird gestreckt) und
  • jeweils nur ein Adapterset für eine ganze Klasse von Druckzylindern, z.B. Bl 600 bis 1300.
Considerable technical advances are generated in the practical use of the current consumption and drive adapter according to the invention:
  • quick and easy opening of the adapter,
  • a technically sufficiently secured power contact,
  • Few individual components (compared to many individual pieces in the past, which were used to assemble such approaches),
  • improved concentricity of the printing cylinder due to the elimination of the deflection (the cylinder axis is stretched) and
  • Only one adapter set for a whole class of printing cylinders, e.g. Bl 600 to 1300.
