Der Adapter sollte zugleich leicht zu handhaben und - v.a. - rasch und einfach anbring- bzw. entfernbar sein.The adapter should also be easy to use and - above all - quick and easy to attach or remove.
Durch den auch für den Fachmann überraschenden und zugleich einfachen Aufbau des erfindungsgemässen Stromzuführungs- und Antriebs-Adapters werden die obigen Aufgaben technisch genügend erfüllt.Due to the surprising and at the same time simple construction of the power supply and drive adapter according to the invention which is also surprising for the person skilled in the art, the above tasks are technically sufficiently fulfilled.
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.
- 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 . The named sealing ring has on its free side a contact ring for the purpose of securing the electrical contact to the front side of the printing cylinder, the said side is optionally provided with a corresponding current-drawing cone.
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
- dass schliesslich der bzw. die Druckzylinder mittels des Gesamt-Stromzuführungs- und Antriebs-Adapters im Galvanikbad gedreht wird/werden, wobei dem/den Druckzylinder(n) über mindestens eine fest angeordnete Elektrode, über den Stromaufnahmezylinder, über den Kolben mit Stromzuführungs-Rohrkörper sowie - gegebenenfalls - über Konus-Adapterstücke der zur Bearbeitung notwendige elektrische Strom zu- bzw. abgeführt wird.
- that one or more than one pressure cylinder of different bale lengths, possibly connected to one another, is / are positioned and fixed in it on the basis of the axes or auxiliary axes,
- that the power supply tubular bodies are then advanced by means of displacement of the pistons to such an extent that the end face of the said tubular bodies meet on both sides on the current-carrying opposite side of the pressure cylinder, whereupon the power supply tubular bodies are held in this position, and
- that the pressure cylinder (s) is / are finally rotated in the electroplating bath by means of the total current supply and drive adapter, the pressure cylinder (s) being connected via at least one fixed electrode, via the current absorption cylinder, via the piston with the current supply tube body and - if necessary - the electrical current required for processing is fed in or out via cone adapter pieces.
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.
Es zeigen
- die Figur 1 eine schematische Darstellung der Hauptkomponenten des erfindungsgemässen Stromzuführungs- und Antriebs-Adapters,
- die Figur 2 eine halbkonstruktive Schnitt-Darstellung einer ersten bevorzugten Ausführungsform des genannten Adapters und
- die Figur 3 eine halbkonstruktive Schnitt-Darstellung einer zweiten bevorzugten Ausführungsform des Adapters.
- 1 shows a schematic illustration of the main components of the power supply and drive adapter according to the invention,
- 2 shows a semi-constructive sectional view of a first preferred embodiment of the adapter mentioned and
- 3 shows a semi-constructive sectional view of a second preferred embodiment of the adapter.
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
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
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
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
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
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
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.
- 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.
