Description

Die Erfindung betrifft eine Steuervorrichtung für die Konservierung von metallischen Bauteilen und Kraftfahrzeugkarosserien durch Aufbringen eines Korrosionsschutzmittels mit den im Oberbegriff des Anspruchs 1 genannten Merkmalen. Außerdem betrifft die Erfindung eine Anlage zum Konservieren von metallischen Bauteilen und von Kraftfahrzeugkarosserien durch Aufbringen eines Korrosionsschutzmittels mit einer derartigen Steuervorrichtung.The invention relates to a control device for the preservation of metallic components and motor vehicle bodies by applying a corrosion inhibitor with the features mentioned in the preamble of claim 1. In addition, the invention relates to a system for preserving metallic components and motor vehicle bodies by applying a corrosion inhibitor with such a control device.

Aus dem Stand der Technik ist es bekannt, die Konservierung von metallischen Bauteilen und Hohlräumen von Kraftfahrzeugkarosserien durch Aufbringen eines Korrosionsschutzmittels, insbesondere eines erhitzten Wachses, durchzuführen. Die Konservierung dient dem Oberflächenschutz und verhindert eine Korrosion der metallischen Bauteile bzw. der Kraftfahrzeugkarosserie. Eine Anlage für die Konservierung weist ein Flutbecken auf, das bei der Konservierung der Kraftfahrzeugkarosserie abtropfendes Wachs auffängt und in einen Wachsvorratsbehälter zurückführt. Der Wachsvorratsbehälter ist mit einer Heizvorrichtung versehen, um das im Vorratsbehälter enthaltende Wachs auf einer Verarbeitungstemperatur, von etwa 120 Grad Celsius zu halten. Vom Wachsvorratsbehälter führt eine eine Pumpe enthaltende Wachs-Speiseleitung zu einer rohrförmigen Versorgungsleitung, die üblicherweise als Ringleitung ausgebildet ist und längs der Seitenwände des Flutbeckens verläuft. Die Ringleitung wird von mehreren Steuerventilen durchsetzt, an deren stirnseitigen Auslassöffnungen als flexible Schläuche ausgebildete Zuführleitungen für das Korrosionsschutzmittel zu einer Flutstelle angeschlossen sind. Die Zuführleitungen sind an dem gegenüberliegenden Ende an üblicherweise vertikal orientierte, fest mit der Anlage verbundene Flutdüsen angeschlossen. Die zu konservierenden Hohlräume weisen an der Unterseite der Fahrzeugkarosserie liegende Öffnungen auf, über die das Korrosionsschutzmittel mittels der Flutdüsen eingebracht wird. Der Aufbau einer derartigen Anlage sowie der Steuervorrichtung umfassend die aus der Ringleitung gespeisten Steuerventile ergibt sich aus der DE 101 15 963 A1 .From the prior art it is known to carry out the preservation of metallic components and cavities of motor vehicle bodies by applying a corrosion inhibitor, in particular a heated wax. The preservation serves to protect the surface and prevents corrosion of the metallic components or of the motor vehicle body. A plant for preservation has a flood basin that collects dripping wax in the preservation of the vehicle body and leads back into a wax reservoir. The wax reservoir is provided with a heater to maintain the wax contained in the reservoir at a processing temperature of about 120 degrees Celsius. From the wax reservoir, a wax feed line containing a pump leads to a tubular supply line, which is usually formed as a loop and runs along the side walls of the flood basin. The ring line is penetrated by a plurality of control valves, are connected to the frontal outlet openings designed as flexible hoses supply lines for the anti-corrosion agent to a flood point. The feed lines are usually vertical at the opposite end connected, firmly connected to the system flood nozzles connected. The cavities to be preserved have openings lying on the underside of the vehicle body, over which the corrosion protection agent is introduced by means of the flood nozzles. The structure of such a system and the control device comprising the fed from the loop control valves results from the DE 101 15 963 A1 ,

Ein Nachteil der dort offenbarten Anlage und Steuervorrichtung besteht darin, dass über jedes Steuerventil der Steuervorrichtung das Korrosionsschutzmittel lediglich einer Flutstelle zugeführt werden kann. Des Weiteren lässt sich der Volumenstrom des Korrosionsschutzmittels nicht ohne weiteres an unterschiedliche, mit der Anlage konservierte metallische Bauteile bzw. Kraftfahrzeugkarosserien anpassen.A disadvantage of the system and control device disclosed therein is that the corrosion protection agent can only be supplied to a flood point via each control valve of the control device. Furthermore, the volume flow of the anticorrosive agent can not be readily adapted to different, preserved with the system metallic components or motor vehicle bodies.

Ausgehend von diesem Stand der Technik liegt der Erfindung daher die Aufgabe zu Grunde, eine Steuervorrichtung der eingangs erwähnten Art zu schaffen, die die Versorgung einer bestimmten Anzahl von Flutstellen mit geringerem konstruktiven Aufwand, insbesondere mit einer geringeren Anzahl an Steuerventilen ermöglicht. Des Weiteren soll eine Anlage zur Konservierung von metallischen Bauteilen und Kraftfahrzeugkarosserien angegeben werden, die einen geringeren konstruktiven Aufwand erfordert.Based on this prior art, the invention is therefore the object of the invention to provide a control device of the type mentioned above, which allows the supply of a certain number of flood points with less design effort, in particular with a smaller number of control valves. Furthermore, a system for the preservation of metallic components and motor vehicle bodies is to be specified, which requires less design effort.

Im Einzelnen wird diese Aufgabe bei einer Steuervorrichtung der eingangs erwähnten Art dadurch gelöst, dass die erste Auslassöffnung und mindestens eine weitere Auslassöffnung außerhalb der Versorgungsleitung radial in dem Schaltrohr angeordnet sind, mindestens ein Auslassdurchgang außerhalb der Versorgungsleitung radial in der Schaltwelle angeordnet ist und im Inneren der Höhlung mündet, wobei jeder Auslassdurchgang und die Auslassöffnungen derart zueinander angeordnet sind, dass in mindestens zwei relativen Winkellagen der Schaltwelle zu dem Schaltrohr stets nur eine Auslassöffnung über die Höhlung und den Vorlauf mit dem Inneren der Versorgungsleitung in für das Korrosionsschutzmittel leitender Verbindung steht.In detail, this object is achieved in a control device of the type mentioned above in that the first outlet opening and at least one further outlet opening are arranged outside the supply line radially in the switching tube, at least one outlet passage outside the supply line is arranged radially in the switching shaft and inside the Cavity opens, each outlet passage and the outlet openings are arranged to each other such that in at least two relative Angular positions of the switching shaft to the switching tube is always only one outlet opening on the cavity and the flow to the interior of the supply line in conductive compound for the anti-corrosion agent.

Durch die erfindungsgemäße radiale Anordnung sämtlicher Auslassöffnungen außerhalb der Versorgungsleitung ist es möglich, mit mindestens einem radial in der drehbaren Schaltwelle angeordneten Auslassdurchgang durch Verdrehen der Schaltwelle selektiv das Korrosionsschutzmittel zu den mit den mehreren Auslassöffnungen verbundenen Flutstellen zu leiten.The inventive radial arrangement of all outlet openings outside the supply line, it is possible with at least one radially arranged in the rotatable switching shaft outlet passage by rotating the switching shaft selectively to direct the anticorrosion agent to the taps connected to the multiple outlet openings.

Die mindestens zwei relativen Winkellagen zwischen Schaltwelle und Schaltrohr zur selektiven Versorgung der an die Auslassöffnungen angeschlossenen Flutstellen werden durch Verdrehen der Schaltwelle in dem Schaltrohr eingestellt.The at least two relative angular positions between the switching shaft and the switching tube for the selective supply of the flood points connected to the outlet openings are set by turning the switching shaft in the switching tube.

Die Auslassöffnungen in dem Schaltrohr sowie die Auslassdurchgänge in der Schaltwelle können beispielsweise als im Querschnitt runde Durchbohrungen ausgeführt sein. Vorzugsweise stimmt der Querschnitt der Auslassöffnungen mit dem Querschnitt der Auslassdurchgänge überein. Die Auslassdurchgänge in der Schaltwelle werden, sofern sie nicht mit einer Auslassöffnung in vollständiger oder teilweiser Überdeckung stehen, durch die Innenmantelfläche des Schaltrohres verschlossen.The outlet openings in the switching tube and the outlet passages in the switching shaft can be embodied, for example, as through-holes which are round in cross-section. Preferably, the cross section of the outlet openings coincides with the cross section of the outlet passages. The outlet passages in the switching shaft, unless they are with an outlet opening in complete or partial overlap, closed by the inner circumferential surface of the switching tube.

Der im Inneren der Versorgungsleitung angeordnete Vorlauf für jedes Steuerventil bringt in mindestens zwei relativen Winkellagen der Schaltwelle zu dem Schaltrohr die Höhlung im Inneren der Schaltwelle mit dem Inneren der Versorgungsleitung in für das Korrosionsschutzmittel leitende Verbindung. Um diese leitende Verbindungen herzustellen, weist der Vorlauf vorzugsweise mindestens eine radiale Einlassöffnung in dem Schaltrohr, die im Inneren der Versorgungsleitung mündet und mindestens einen radialen Einlassdurchgang in der Schaltwelle, der in der Höhlung mündet, auf, wobei durch Verdrehen der Schaltwelle jede Einlassöffnung des Schaltrohres mit mindestens einem Einlassdurchgang der Schaltwelle in Überdeckung bringbar ist.The arranged in the interior of the supply line flow for each control valve brings in at least two relative angular positions of the switching shaft to the switching tube, the cavity in the interior of the switching shaft with the interior of the supply line in conductive compound for the anti-corrosion agent. In order to produce these conductive connections, the flow preferably has at least one radial inlet opening in the switching tube which is located inside the switching tube Supply line opens and at least one radial inlet passage in the switching shaft, which opens into the cavity, on, by rotation of the switching shaft each inlet opening of the switching tube can be brought into overlap with at least one inlet passage of the switching shaft.

Sofern sämtliche Einlassöffnungen und Einlassdurchgänge des Vorlaufs in Richtung der Längsachsen von Schaltrohr und Schaltwelle nicht axial beabstandet sind, weist das Schaltrohr mindestens eine Einlassöffnung und die Schaltwelle mindestens zwei radial versetzte Einlassdurchgänge auf. Alternativ weist das Schaltrohr mindestens zwei radial versetzte Einlassöffnungen und die Schaltwelle mindestens einen Einlassdurchgang auf.If all inlet openings and inlet passages of the supply line are not axially spaced in the direction of the longitudinal axes of the shift tube and the shift shaft, the shift tube has at least one inlet opening and the selector shaft has at least two radially offset inlet passages. Alternatively, the switching tube has at least two radially offset inlet openings and the switching shaft has at least one inlet passage.

Sofern die Einlassöffnungen oder Einlassdurchgänge in Richtung der Längsachsen von Schaltrohr bzw. Schaltwelle axial beabstandet sind, weist das Schaltrohr mindestens zwei axial beabstandete und radial versetzte Einlassöffnungen und die Schaltwelle mindestens zwei axial beabstandete und radial versetzte Einlassdurchgänge auf.If the inlet openings or inlet passages are axially spaced in the direction of the longitudinal axes of the switching tube or switching shaft, the switching tube has at least two axially spaced and radially offset inlet openings and the switching shaft at least two axially spaced and radially offset inlet passages.

Um in unterschiedlichen relativen Winkellagen der Schaltwelle zu dem Schaltrohr stets nur eine Auslassöffnung über die Höhlung in der Schaltwelle und den Vorlauf mit dem Inneren der Versorgungsleitung in für das Korrosionsschutzmittel leitende Verbindung zu bringen, bestehen unterschiedliche Möglichkeiten der Anordnung der mindestens zwei Auslassöffnungen sowie der mit diesen Auslassöffnungen zusammenwirkenden Auslassdurchgänge in der Schaltwelle, die sich aus den Merkmalen der Unteransprüche 7 - 10 ergeben.In order to bring in different relative angular positions of the switching shaft to the switching tube always only one outlet opening over the cavity in the switching shaft and the flow to the interior of the supply line in conductive compound for the anticorrosive, there are different ways of arranging the at least two outlet openings and with these Outlet openings cooperating exhaust passages in the switching shaft, resulting from the features of the subclaims 7-10.

Um in dem zu konservierenden Hohlraum befindliches überschüssiges Korrosionsschutzmittel über die Zuführleitungen einem Flutbecken zur Wiederverwendung zuzuführen, ist die Steuervorrichtung vorzugsweise derart ausgebildet, dass außerhalb der Versorgungsleitung radial in dem Schaltrohr ein Rücklaufauslass angeordnet ist, ein radial in der Schaltwelle angeordneter Rücklaufdurchgang im Inneren der Höhlung mündet, der durch Verdrehen der Schaltwelle mit dem Rücklaufauslass in dem Schaltrohr in Überdeckung bringbar ist, wobei der Rücklaufdurchgang und jeder Einlassdurchgang in der Schaltwelle derart zueinander angeordnet sind, dass jeder Einlassdurchgang durch das Schaltrohr verschlossen ist, wenn der Rücklaufdurchgang mit dem Rücklaufauslass in Überdeckung steht. Hierdurch wird vermieden, dass aus der Ringleitung unter Druck stehendes Korrosionsschutzmittel durch den Rücklaufauslass zusammen mit dem überschüssigen Korrosionsschutzmittel abfließt. Der Rücklaufauslass befindet sich vorzugsweise an der Unterseite des Schaltrohres, damit das überschüssige Korrosionsschutzmittel drucklos abfließen kann. Die Auslassöffnungen in der Schaltwelle fluchten mit weiteren Durchgängen in der Schaltwelle, wenn der Rücklaufdurchgang mit dem Rücklaufauslass in Überdeckung steht. Hierdurch kann das überschüssige Korrosionsmittel aus den Schläuchen zu den Flutdüsen ungehindert durch den Rücklaufauslass abfließen.In order to supply excess flocculation agent in the cavity to be preserved via the supply lines to a flood basin for reuse, the control device is preferably such formed that outside the supply line radially in the switching tube, a return outlet is arranged, a radially arranged in the switching shaft return passage in the interior of the cavity opens, which can be brought into rotation by turning the switching shaft with the return outlet in the switching tube, wherein the return passage and each inlet passage are arranged in the switching shaft to each other such that each inlet passage is closed by the switching tube when the return passage is in register with the return outlet. This avoids that from the ring line pressurized corrosion protection agent flows through the return outlet together with the excess corrosion inhibitor. The return outlet is preferably located on the underside of the switching tube so that the excess corrosion inhibitor can flow off without pressure. The exhaust ports in the shift shaft are aligned with further passages in the shift shaft when the return passage is in register with the return port. As a result, the excess corrosive agent from the hoses to the flood nozzles flow freely through the return outlet.

Um die Durchflussmenge des Korrosionsschutzmittels von 0 bis zu einem vorbestimmten Maximalwert kontinuierlich einstellen zu können, sind jede Auslassöffnung und jeder Auslassdurchgang derart zueinander angeordnet, dass durch Verdrehen der Schaltwelle die Größe der Überdeckung, das heißt die Größe des freien Querschnitts zwischen jeder Auslassöffnung und jedem Auslassdurchgang verändert wird. Alternativ oder zusätzlich kann jede Einlassöffnung und jeder Einlassdurchgang des Vorlaufs derart zueinander angeordnet sein, dass durch Verdrehen der Schaltwelle die Größe der Überdeckung, das heißt die Größe des freien Querschnitts zwischen jeder Einlassöffnung und jedem Einlassdurchgang kontinuierlich verändert wird.In order to be able to continuously adjust the flow rate of the anticorrosion agent from 0 to a predetermined maximum value, each outlet opening and each outlet passage are arranged to each other such that by rotating the switching shaft, the size of the overlap, that is, the size of the free cross section between each outlet opening and each outlet passage is changed. Alternatively or additionally, each inlet opening and each inlet passage of the flow can be arranged to each other such that by rotating the switching shaft, the size of the overlap, that is, the size of the free cross section between each inlet opening and each inlet passage is changed continuously.

Der Antrieb zum Verdrehen der Schaltwelle ist vorzugsweise ein Stellmotor, insbesondere ein Servo-Antrieb. Der Vorteil eines Servo-Antriebs besteht in der hohen Genauigkeit der Drehbewegung des Rotors, die eine exakte Verdrehung der Schaltwelle in die mindestens zwei relativen Winkellagen der Schaltwelle zu dem Schaltrohr ermöglicht. Des Weiteren ist der Servo-Antrieb für die kontinuierliche Einstellung der Überdeckung zwischen jeder Auslassöffnung und jedem Auslassdurchgang bzw. jeder Einlassöffnung und jedem Einlassdurchgang geeignet. Des Weiteren lässt sich ein Servomotor vorteilhaft mit einer Programmsteuerung verbinden, die derart programmiert ist, dass der Drehwinkel der mit dem Stellmotor verbundenen Schaltwelle und damit die Flutstelle und/oder die Menge an Korrosionsschutzmittel für die Konservierung jedes Bauteils präzise einstellbar ist.The drive for rotating the switching shaft is preferably a servo motor, in particular a servo drive. The advantage of a servo drive is the high accuracy of the rotational movement of the rotor, which allows an exact rotation of the switching shaft in the at least two relative angular positions of the switching shaft to the switching tube. Further, the servo drive is suitable for continuously adjusting the coverage between each exhaust port and each exhaust port and each intake port. Furthermore, a servomotor can advantageously be connected to a program controller which is programmed in such a way that the angle of rotation of the control shaft connected to the servomotor and thus the flooding point and / or the amount of anticorrosion agent for the preservation of each component can be precisely adjusted.

Eine bevorzugte Anlage zum Konservieren von metallischen Bauteilen sowie von Kraftfahrzeugkarosserien ergibt sich aus den Merkmalen der Ansprüche 16 und 17.A preferred system for preserving metallic components and motor vehicle bodies results from the features of claims 16 and 17.

Für die nachfolgende Beschreibung wird davon ausgegangen, dass es sich bei dem Korrosionsschutzmittel um ein Wachs handelt, welches einen Schmelzpunkt von beispielsweise 90 Grad Celsius hat und in der erfindungsgemäßen Anlage für die Konservierung von metallischen Bauteilen und Kraftfahrzeugkarosserien auf einer Verarbeitungstemperatur von beispielsweise 120 Grad Celsius gehalten wird.For the following description it is assumed that it is the corrosion inhibitor is a wax having a melting point of, for example, 90 degrees Celsius and in the inventive system for the Conservation of metallic components and motor vehicle bodies is maintained at a processing temperature of, for example, 120 degrees Celsius.

Figur 1 zeigt einen Querschnitt durch eine rohrförmige Versorgungsleitung (1) zur Zuführung des Wachses zu mehreren Steuerventilen (2), die im Längsabstand voneinander in die Versorgungsleitung (1) eingesetzt sind. Das Steuerventil (2) umfasst ein die Versorgungsleitung (1) durchsetzendes Schaltrohr (3), in dem drehbar eine Schaltwelle (4) gelagert ist. FIG. 1 shows a cross section through a tubular supply line (1) for supplying the wax to a plurality of control valves (2), which are inserted at a longitudinal distance from each other in the supply line (1). The control valve (2) comprises a the supply line (1) passing through the switching tube (3) in which a control shaft (4) is rotatably mounted.

An den beiden diametral gegenüberliegenden Durchtrittsstellen des Schaltrohrs (3) durch die Versorgungsleitung (1) befinden sich jeweils rohrförmige Ansatzstücke (5, 6) an der Versorgungsleitung (1), die endseitig einen Flansch (7, 8) aufweisen. Die Ansatzstücke (5, 6) umgeben das Schaltrohr an der Durchtrittsstelle dichtend, so dass kein Wachs zwischen dem Schaltrohr (3) und der Durchtrittsöffnung durch die Wandung der Versorgungsleitung (1) austreten kann. Mit den Flanschen (7, 8) sind ein linker und ein rechter Ventilkörper (9, 10) verschraubt. Der linke und rechte Ventilkörper (9, 10) nehmen einen Teil des Überstandes des Schaltrohres (3) außerhalb der Versorgungsleitung (1) auf. Die in dem Schaltrohr (3) drehbar angeordnete Schaltwelle (4) ist mit einer zu deren Längsachse koaxialen Höhlung versehen, die beispielsweise als Sacklochbohrung von der in Figur 1 linken Seite in die Schaltwelle (3) eingebracht ist und sich bis zu einem Vorlauf (13) im Inneren (12) der Versorgungsleitung (1) erstreckt. Stirnseitig ist die Höhlung durch einen Deckel verschlossen. Der Vorlauf (13) bringt in zwei unterschiedlichen relativen Winkellagen der Schaltwelle (4) zu dem Schaltrohr (3) die Höhlung im Inneren der Schaltwelle (4) mit dem Inneren (12) der Versorgungsleitung (1) in für den Wachs leitende Verbindung, so dass das Wachs aus der Versorgungsleitung (1) in die Höhlung einströmt.
Der Vorlauf (13) wird in dem dargestellten Ausführungsbeispiel von zwei axial beabstandeten und radial versetzten Einlassöffnungen (14) in dem Schaltrohr (3) gebildet, die im Inneren (12) der Versorgungsleitung (1) münden. Von den beiden Einlassöffnungen ist lediglich die an der Unterseite des Schaltrohrs (3) angeordnete Einlassöffnung (14) erkennbar, während die axial beabstandete und radial versetzte Einlassöffnung sich auf der in Figur 1 nicht erkennbaren Rückseite des Schaltrohres (3) befindet.At the two diametrically opposite passages of the switching tube (3) through the supply line (1) are each tubular extension pieces (5, 6) on the supply line (1), the end a flange (7, 8). The extension pieces (5, 6) sealingly surround the switching tube at the point of passage so that no wax can escape through the wall of the supply line (1) between the switching tube (3) and the passage opening. With the flanges (7, 8), a left and a right valve body (9, 10) are screwed. The left and right valve body (9, 10) take part of the supernatant of the switching tube (3) outside the supply line (1). The in the switching tube (3) rotatably mounted switching shaft (4) is provided with a coaxial with its longitudinal axis cavity, for example, as a blind hole from the in FIG. 1 is introduced on the left side in the switching shaft (3) and extends to a feed line (13) in the interior (12) of the supply line (1). The front side of the cavity is closed by a lid. The lead (13) brings in two different relative angular positions of the switching shaft (4) to the switching tube (3), the cavity in the interior of the switching shaft (4) with the interior (12) of the supply line (1) in the wax conductive compound, so that the wax from the supply line (1) flows into the cavity.
The flow (13) is formed in the illustrated embodiment of two axially spaced and radially offset inlet openings (14) in the switching tube (3), which open in the interior (12) of the supply line (1). Of the two inlet openings, only the inlet opening (14) arranged on the underside of the switching tube (3) can be seen, while the axially spaced and radially offset inlet opening is located on the inlet opening (14) FIG. 1 unrecognizable back of the switching tube (3) is located.

Die Schaltwelle (4) verfügt über zwei um denselben Betrag axial beabstandete Einlassdurchgänge (15), wobei durch Verdrehen der Schaltwelle (4) in eine der beiden relativen Winkellagen zwischen Schaltwelle (4) und Schaltrohr (3) jede der beiden Einlassöffnungen (14) des Schaltrohres (3) mit einem der beiden Einlassdurchgänge (15) in der Schaltwelle (4) in Überdeckung bringbar ist. Die Einlassdurchgänge (15) sind derart radial versetzt in der Schaltwelle (4) angeordnet, dass stets nur einer der beiden Einlassdurchgänge (15) mit einer der beiden Einlassöffnungen (14) in Überdeckung steht.The selector shaft (4) has two inlet passages (15) spaced axially by the same amount, wherein each of the two inlet openings (14) of the actuator can be rotated by turning the selector shaft (4) into one of the two relative angular positions between the selector shaft (4) and the selector shaft (3) Switching tube (3) with one of the two inlet passages (15) in the switching shaft (4) can be brought into overlap. The inlet passages (15) are arranged radially offset in the switching shaft (4) such that always only one of the two inlet passages (15) is in register with one of the two inlet openings (14).

An dem linken Überstand des Schaltventils weist das Schaltrohr (3) zwei axial beabstandete und radial versetzte Auslassöffnungen (16 a, b) und die Schaltwelle zwei axial um denselben Betrag beabstandete, jedoch radial nicht versetzte Auslassdurchgänge (17a, b) auf, wobei durch Verdrehen der Schaltwelle (4) jede der beiden Auslassöffnungen (16 a, b) des Schaltrohres (3) mit einem der beiden Auslassdurchgänge (17a, b) in der Schaltwelle (4) in Überdeckung bringbar ist. In den linken Ventilkörper (9) sind fluchtend mit den radialen Auslassöffnungen (16 a, b) Schlauchanschlüsse (18a, b) eingeschraubt, in die die Auslassöffnungen (16 a, b) des Schaltrohres (3) einmünden. Die Schlauchanschlüsse (18a, b) sind mit den der Übersichtlichkeit halber nicht dargestellten Zuführleitungen für das Korrosionsschutzmittel zu zwei Flutstellen verbunden.At the left projection of the switching valve, the switching tube (3) has two axially spaced and radially offset outlet openings (16 a, b) and the switching shaft two axially spaced by the same amount, but not radially offset outlet passages (17 a, b), wherein by twisting the switching shaft (4) each of the two outlet openings (16 a, b) of the switching tube (3) with one of the two outlet passages (17 a, b) in the switching shaft (4) can be brought into overlap. In the left valve body (9) are aligned with the radial outlet openings (16 a, b) screwed hose connections (18 a, b) into which the outlet openings (16 a, b) of the switching tube (3) open. The hose connections (18a, b) are not shown with the sake of clarity Supply lines for the anti-corrosion agent connected to two flood points.

In dem Überstand des Schaltrohrs (3) außerhalb der Versorgungsleitung (1) ist radial in dem Schaltrohr (3) ein nach unten weisender Rücklaufauslass (19) angeordnet. Ein radial in der Schaltwelle (4) angeordneter Rücklaufdurchgang (20) mündet, ebenso wie die Auslassdurchgänge (17a, b) im Inneren der Höhlung. Der Rücklaufdurchgang (20) ist durch Verdrehen der Schaltwelle (4) mit dem Rücklaufauslass (19) in Überdeckung bringbar, wobei der Rücklaufdurchgang (20) und die beiden Einlassdurchgänge (15) in der Schaltwelle derart zueinander angeordnet sind, dass die beiden Einlassdurchgänge (15) durch das umgebene Schaltrohr (3) verschlossen sind, wenn der Rücklaufdurchgang (20) mit dem Rücklaufauslass (19) in Überdeckung steht und überschüssiges Wachs durch den an der Unterseite in den linken Ventilkörper (9) eingeschraubten Schlauchanschluss (21) in das der Übersichtlichkeit halber nicht dargestellte beheizbare Flutbecken der Anlage zum Konservieren geleitet wird. Hierdurch wird vermieden, dass aus der Ringleitung unter Druck stehendes Korrosionsschutzmittel durch den Rücklaufauslass zusammen mit dem überschüssigen Korrosionsschutzmittel abfließt. Die Auslassöffnungen (16a, b) in der Schaltwelle fluchten mit weiteren, in der Figur nicht dargestellten Durchgängen in der Schaltwelle (4), wenn der Rücklaufdurchgang (20) mit dem Rücklaufauslass (19) in Überdeckung steht. Hierdurch kann das überschüssige Korrosionsmittel aus den Zuführungsleitungen ungehindert durch den Rücklaufauslass (19) abfließen. Die weiteren, jeweils radial zu den Auslassdurchgängen (17a, b) versetzt angeordneten Durchgänge werden durch die Schaltwelle (4) verschlossen, sobald der Rücklaufdurchgang (20) mit dem Rücklaufauslass (19) nicht mehr in Überdeckung steht.In the projection of the switching tube (3) outside the supply line (1) is arranged radially in the switching tube (3) has a downwardly facing return outlet (19). A return passage (20) disposed radially in the shift shaft (4) opens, as well as the outlet passages (17a, b) in the interior of the cavity. The return passage (20) can be brought into coincidence by turning the selector shaft (4) with the return outlet (19), the return passage (20) and the two inlet passages (15) in the selector shaft being arranged relative to one another such that the two inlet passages (15 ) are closed by the surrounding switching tube (3) when the return passage (20) with the return outlet (19) is in overlap and excess wax through the at the bottom in the left valve body (9) screwed hose connection (21) in the clarity half not shown heated flood basin of the plant for preserving is passed. This avoids that from the ring line pressurized corrosion protection agent flows through the return outlet together with the excess corrosion inhibitor. The outlet openings (16a, b) in the switching shaft are aligned with further, not shown in the figure passages in the switching shaft (4) when the return passage (20) with the return outlet (19) is in register. As a result, the excess corrosive agent from the supply lines can flow unhindered through the return outlet (19). The further, in each case radially offset to the outlet passages (17a, b) arranged passages are closed by the switching shaft (4) as soon as the return passage (20) with the return outlet (19) is no longer in register.

Die Schaltwelle (4) ragt über den rechten Überstand des Schaltrohres (3) hinaus. Dieses Ende ist über eine Kupplung (22) mit einem als Servomotor ausgeführten Antrieb (23) zum Verdrehen der Schaltwelle (4) verbunden. Der Servomotor wird von einer nicht dargestellten Programmsteuerung angesteuert, die derart programmiert ist, dass der Drehwinkel der mit dem Servomotor verbundenen Schaltwelle (4) in unterschiedlichen relativen Winkellagen zwischen Schaltwelle (4) und Schaltrohr (3) einstellbar ist.The switching shaft (4) protrudes beyond the right projection of the switching tube (3). This end is connected via a coupling (22) with a drive (23) designed as a servomotor for rotating the switching shaft (4). The servomotor is controlled by a program control, not shown, which is programmed such that the angle of rotation of the connected to the servo motor switching shaft (4) in different relative angular positions between the switching shaft (4) and switching tube (3) is adjustable.

In einer ersten relativen Winkellage gelangt die im Bild linke Einlassöffnung (14) mit dem im Bild nicht dargestellten Einlassdurchgang (15) in Überdeckung. Gleichzeitig befindet sich die Auslassöffnung (16 b) in Überdeckung mit dem Auslassdurchgang (17b), so dass über den Schlauchanschluss (18 b) Wachs zu der ersten Flutstelle gelangt.In a first relative angular position, the inlet opening (14) left in the picture coincides with the inlet passage (15) not shown in the figure. At the same time, the outlet opening (16 b) is in overlap with the outlet passage (17 b), so that via the hose connection (18 b) wax reaches the first flooding point.

In einer zweiten Winkellage steht die im Bild nicht dargestellte Einlassöffnung (14) an der Vorderseite des Schaltrohres (3) mit dem im Bild dargestellten Einlassdurchgang (15) in Überdeckung (vgl. Figur 1). Gleichzeitig befindet sich die Auslassöffnung (16a) in Überdeckung mit dem Auslassdurchgang (17a), so dass über den Schlauchanschluss (18a) Wachs zu der zweiten Flutstelle gelangt.In a second angular position, the inlet opening (14) (not shown in the figure) on the front side of the switching tube (3) is in register with the inlet passage (15) shown in the image (cf. FIG. 1 ). At the same time, the outlet opening (16a) is in register with the outlet passage (17a), so that wax reaches the second flooding point via the hose connection (18a).

In einer dritten Winkellage sind die Einlassdurchgänge (15) in der Schaltwelle (4) durch das Schaltrohr (3) beide verschlossen, während der Rücklaufauslass (19) und der Rücklaufdurchgang (20) in Überdeckung stehen, so dass Wachs über den Schlauchanschluss (21) sowie eine daran angeschlossene Leitung in das nicht dargestellte Flutbecken zurückfließen kann.In a third angular position, the inlet passages (15) in the switching shaft (4) are both closed by the switching tube (3), while the return outlet (19) and the return passage (20) are in overlap, so that wax via the hose connection (21) and a line connected thereto can flow back into the flood basin, not shown.

Bei längeren Unterbrechungen des Flutvorgangs über die erste bzw. zweite Flutstelle ist es erforderlich, dass in den nicht dargestellten Zuführleitungen befindliche Wachs zu entfernen, um somit ein Verstopfen der Zuführleitungen durch erstarrtes Wachs zu verhindern.For longer interruptions of the flood process over the first or second flood point, it is necessary that in the not Removing wax shown to prevent clogging of the feed lines by solidified wax.

Der Vorteil der erfindungsgemäßen Lösung besteht darin, dass jedes Steuerventil mindestens zwei Flutstellen mit Wachs versorgen kann. Eine erfindungsgemäße Anlage zur Konservierung von metallischen Bauteilen bzw. zur Hohlraumkonservierung kann daher mit insgesamt weniger Steuerventilen in der Steuervorrichtung eine gleiche Anzahl von Flutstellen mit Wachs fluten. Insgesamt wird daher der Aufwand für die Steuervorrichtung der Anlage deutlich reduziert.The advantage of the solution according to the invention is that each control valve can provide at least two flooding with wax. A plant according to the invention for the preservation of metallic components or for cavity preservation can therefore flooding an equal number of flooding sites with wax with a total of fewer control valves in the control device. Overall, therefore, the cost of the control device of the system is significantly reduced.

Der programmgesteuerte Servomotor hat darüber hinaus den Vorteil, dass für jede Flutstelle der Volumenstrom des Wachses individuell mit Hilf eines insbesondere PC-basierten Programms einstellbar ist.The program-controlled servomotor has the additional advantage that for each flood the volumetric flow of the wax can be individually adjusted by means of a particular PC-based program.

Eine Anlage (24) für die Konservierung weist ein Flutbecken (25) auf, das bei der Konservierung der Kraftfahrzeugkarosserie abtropfendes Wachs auffängt und in einen in Figur 2 nicht dargestellten Wachsvorratsbehälter zurückführt. Der Wachsvorratsbehälter ist mit einer Heizvorrichtung versehen, um das im Vorratsbehälter enthaltende Wachs auf einer Verarbeitungstemperatur, von etwa 120 Grad Celsius zu halten. Vom Wachsvorratsbehälter führt eine eine Pumpe enthaltende Wachs-Speiseleitung zu der rohrförmigen Versorgungsleitung (1), die als Ringleitung ausgebildet ist und längs der Seitenwände (26) des Flutbeckens (25) verläuft. Die Ringleitung wird von mehreren Steuerventilen (2) durchsetzt, an deren beiden Auslassöffnungen (16a, b) mittels der Schlauchanschlüsse (18a, b) zwei als flexible Schläuche (27a, b) ausgebildete Zuführleitungen für den Heißwachs zu den Flutstellen (28a, b) angeschlossen sind. Die zu konservierenden Hohlräume (29a, b) weisen an der Unterseite der Fahrzeugkarosserie liegende Öffnungen auf, über die der Heißwachs mittels Flutdüsen (30a, b) eingebracht wird.A plant (24) for preservation has a flood basin (25), which collects dripping wax in the preservation of the vehicle body and in a FIG. 2 not shown wax reservoir returns. The wax reservoir is provided with a heater to maintain the wax contained in the reservoir at a processing temperature of about 120 degrees Celsius. From the wax reservoir, a wax feed line containing a pump leads to the tubular supply line (1), which is formed as a loop and runs along the side walls (26) of the flood basin (25). The ring line is penetrated by a plurality of control valves (2), at the two outlet openings (16a, b) by means of the hose connections (18a, b) two flexible hoses (27a, b) formed supply lines for the hot wax to the flood points (28a, b) are connected. The cavities to be preserved (29a, b) have at the bottom of the vehicle body openings lying over which the hot wax by means of flood nozzles (30a, b) is introduced.

Die Befestigung der Versorgungsleitung (1) erfolgt an den Seitenwänden (26) des Flutbeckens 25 über in den Flutbeckeninnenraum (33) ragende Traversen (31). In den Seitenwänden (26) des Flutbeckens (25) befinden sich Heizrohre (32), in denen Heißwasser zur Beheizung des Flutbeckeninnenraums (33) auf zirka 90°C gefördert wird. Außerdem sind im Flutbeckeninnenraum (33) Heizrohre (34) angeordnet, die bei Bedarf die Flutstellen (28a, b) ebenfalls beheizen. Durch die Erwärmung des Flutbeckeninnenraums (33) wird ein Erstarren des Heißwachses in den zu den Flutstellen 28a, b führenden Schläuchen (27a, b) vermieden. Ein zusätzliches Beheizen der Schläuche (27a, b) ist nicht erforderlich.The attachment of the supply line (1) takes place on the side walls (26) of the flood basin 25 in the trough interior (33) projecting trusses (31). In the side walls (26) of the flood basin (25) are heating tubes (32), in which hot water for heating the flood basin interior (33) is conveyed to approximately 90 ° C. In addition, in the trough interior (33) heating tubes (34) are arranged, which also heat the flood points (28a, b) as needed. The heating of the trough interior (33) prevents solidification of the hot wax in the hoses (27a, b) leading to the flood points 28a, b. An additional heating of the tubes (27a, b) is not required.

In dem Flutbecken (25) sind mehrere Flutstellen (28a,b) zur Hohlraumkonservierung von Hohlräumen (29a, b) angeordnet. Jeweils zwei Flutstellen (28a, b) werden von einem Steuerventil (2) in der Ringleitung (1) nacheinander geflutet. Durch die Flutdüsen (30a, b) werden die Hohlräume (29a, b) der zu konservierenden Bauteile fast vollständig mit Heißwachs geflutet, so dass die zu konservierenden Flächen vollständig mit Heißwachs benetzt werden. Nach Beendigung des Flutvorganges erfolgt eine Entleerung der Hohlräume von dem nicht benötigten Heißwachs, das danach über das Flutbecken (25) der Anlage (24) Wieder zugeführt wird.In the flood basin (25) a plurality of flooding points (28a, b) for cavity preservation of cavities (29a, b) are arranged. In each case two flood points (28a, b) are flooded one after the other by a control valve (2) in the loop (1). By the flood nozzles (30a, b), the cavities (29a, b) of the components to be preserved are almost completely flooded with hot wax, so that the surfaces to be preserved are completely wetted with hot wax. After completion of the flooding process, an emptying of the cavities of the unneeded hot wax, which is then fed back via the flood basin (25) of the system (24).

Der Antrieb (23) der Steuervorrichtung liegt außerhalb des Flutbeckens (25).The drive (23) of the control device is outside the flood basin (25).
