Description

Die Erfindung bezieht sich auf eine Mehrkomponenten-Dosieranlage mit einer Vielzahl von Dosierventilen und einer Kupplungsvorrichtung für ein Steuerventil.The invention relates to a multi-component dosing system a variety of metering valves and a coupling device for a control valve.

Zur Herstellung von Flüssigkeitsmischungen, wie Parfümen, Aromen, Farben oder dgl., bestehend aus einer Vielzahl unterschiedlicher Komponenten, werden in der Praxis gravimetrisch oder volumetrisch arbeitende Dosieranlagen eingesetzt. Abhängig von der Anzahl der Komponenten weisen die Dosieranlagen bis zu 500 einzelne Dosierventile auf. Die Anordnung der Dosierventile in der Dosieranlage ist kreisförmig, linear oder auch frei wählbar, jedoch durch die Abmessung der zu befüllenden Gebinde begrenzt.For the preparation of liquid mixtures, such as perfumes, Aromas, colors or the like, consisting of a variety different components, are in practice dosing systems operating gravimetrically or volumetrically used. Depending on the number of components, the Dosing systems up to 500 individual dosing valves. The Arrangement of the metering valves in the metering system is circular, linear or freely selectable, however by the Dimension of the containers to be filled limited.

Die Steuerventile der Dosierventile sind entweder direkt an den einzelnen Dosierventilen oder in einem separaten Schaltschrank untergebracht. Die direkte Anbringung der Steuerventile an zugehörigen Dosierventilen ist aufgrund von Platzproblemen häufig nicht möglich. Die Unterbringung der Steuerventile in einem Schaltschrank ist insbesondere bei Anlagen erforderlich, welche den besonderen Auflagen des Explosionsschutzes unterliegen. Die Steuerventile sind in einem explosionsgeschützten Bereich des Schaltschrank angeordnet und jeweils mit einer gesonderten elektrischen Verkabelung sowie einer aufwendigen Verschlauchung mit dem jeweiligen Dosierventil verbunden. Mehrere Schläuche werden zu einem Bündel zusammengefaßt, wodurch die Übersichtlichkeit in der Dosieranlage nachteilig beeinträchtigt wird.The control valves of the metering valves are either directly on the individual dosing valves or in a separate one Control cabinet housed. The direct attachment of the Control valves on associated metering valves is due to Space problems often not possible. The placement of the Control valves in a control cabinet is particularly useful for Plants required that meet the special requirements of the Subject to explosion protection. The control valves are in an explosion-protected area of the control cabinet arranged and each with a separate electrical Wiring and complex hoses with the respective metering valve connected. Multiple hoses become too summarized in a bundle, whereby the clarity in the dosing system is adversely affected.

In der DE 92 09 384 U1 ist eine Abgabeeinrichtung für verschiedene Flüssigkeiten über einen gemeinsamen Abgabekopf mit je einem Dosierzylinder pro Flüssigkeitskomponente beschrieben. Jeder Dosierzylinder im Abgabekopf weist ein 2/2-Ventil zur Steuerung des zugehörigen Dosierventiles auf. Die Anschaffung einer solchen Dosiereinrichtung ist aufgrund der hohen Anzahl von Steuerventilen kostenintensiv.DE 92 09 384 U1 describes a delivery device for different liquids via a common dispensing head with one dosing cylinder per liquid component described. Each dosing cylinder in the dispensing head has a 2/2 valve to control the associated metering valve. The Purchase of such a metering device is due to the high number of control valves costly.

Weiterhin ist aus der DE 37 09 554 A1 eine Vorrichtung zum kontinuierlichen Dosieren und Mischen von Flüssigkeitsmischungen in verschiedene Mischbehältern bekannt, in welcher für jede Flüssigkeitskomponente eine eigene Dosiereinrichtung mit einem Dosierzylinder und zwei zugeordneten, den Dosierzylinder schaltenden Steuerzylindern vorgesehen ist. Eine derartige Dosiereinrichtung ist aufgrund ihres großen Platzbedarf nur zum Einsatz in Dosieranlagen zur Herstellung von Flüssigkeitsmischungen aus wenigen Komponenten geeignet.Furthermore, DE 37 09 554 A1 describes a device for continuous dosing and mixing of liquid mixtures known in different mixing containers, in which a separate dosing device for each liquid component with a dosing cylinder and two assigned, the Dosing cylinder switching control cylinders is provided. Such a metering device is due to its large size Space requirement only for use in dosing systems for manufacturing of liquid mixtures from a few components.

Die bekannten Mehrkomponenten-Dosieranlagen haben daher den Nachteil hoher Kosten und eines großen Installationsaufwandes. Wegen der unübersichtlichen Installation treten auch bei der Wartung und Reparatur der Dosiereinrichtung Probleme auf. Eine eindeutige visuelle Zuordnung der einzelnen Dosierventile zu ihrem Steuerventil ist nicht zuverlässig gewährleistet.The known multi-component dosing systems therefore have the Disadvantage of high costs and a large installation effort. Because of the confusing installation, the Maintenance and repair of the dosing device problems. A clear visual assignment of the individual dosing valves their control valve is not reliably guaranteed.

Es ist daher Aufgabe der Erfindung eine Alternative zu diesem bekannten Stand der Technik zu schaffen, durch welche die genannten Nachteile vermieden werden. Diese Aufgabe wird durch eine Mehrkomponenten-Dosieranlage mit den Merkmalen des Patentanspruches 1 gelöst. It is therefore the object of the invention to provide an alternative to this to provide known prior art through which the mentioned disadvantages can be avoided. This task is accomplished by a multi-component dosing system with the features of Claim 1 solved.

Durch den Einsatz der Kupplungsvorrichtung für das Steuerventil ist nur noch ein einziges Schaltelement für alle Dosierventile erforderlich, da während des Mischvorganges der Flüssigkeitsmischung das Fahrzeug der Kupplungsvorrichtung mit dem zum Steuerventil gehörenden Kupplungsstück nacheinander zu der Position des Kupplungsgegenstückes verfährt, welches dem durch das Rezepturprogramm vorgegebene Dosierventil zugeordnet ist, und dort in Kupplungsposition das Steuerventil mit dem entsprechenden Dosierventil verbunden ist, so daß das Steuerventil das Dosierventil von der Schließstellung in die Abgabestellung schaltet. Beim Kuppeln wird das Kupplungsstück von dem Stellorgan quer zur Fahrbahn mit dem jeweiligen Kupplungsgegenstück in Deckung gebracht.By using the coupling device for the Control valve is only a single switching element for everyone Dosing valves required because during the mixing process Liquid mixture using the vehicle's coupling device the coupling piece belonging to the control valve one after the other moves the position of the coupling counterpart, which the assigned by the recipe program predetermined metering valve and there in the coupling position the control valve with the corresponding metering valve is connected so that Control valve the metering valve from the closed position to the Delivery position switches. When coupling, the coupling piece from the actuator across the lane with the respective Coupling counterpart brought into cover.

In der Entkupplungsposition sind alle Dosierventile geschlossen und in den verschiedenen Kupplungspositionen des Steuerventil besteht jeweils eine Verbindung zu dem vorgegebenen, in Abgabestellung zu schaltenden Dosierventil. Die einfach lösbare Verbindung zwischen dem Steuerventil und dem vorgegebenen Dosierventil aufgrund der erfindungsgemäßen Kupplungsvorrichtung gestattet es, die Anzahl an Steuermittel in der Dosieranlage erheblich zu reduzieren, was sich vorteilhaft in einem geringeren Installationsaufwand und niedrigeren Kosten auswirkt.All metering valves are in the uncoupling position closed and in the various coupling positions of the Control valve is connected to each predetermined metering valve to be switched in the delivery position.

In der Kupplungsposition ist durch die Kupplungsvorrichtung das aus Teilen des Kupplungstückes sowie des Kupplungsgegenstückes bestehende Steuerventil für das zu öffnende Dosierventil bereitgestellt. Das Dosierventil wird mittels Magnetventil aus der anfänglichen Schließstellung in die Abgabestellung geschaltet, indem der Spulenstrom eingeschaltet wird, wodurch der Anker zur Spule gezogen wird und gleichzeitig der Abschlußkörper die Abgabeöffnung des Dosierventiles freigibt. Nach Abschalten des Spulenstromes wird der Anker durch eine Rückstellfeder in die Schließstellung des Dosierventiles zurückgebracht und dort gehalten, so daß der Abschlußkörper die Abgabeöffnung verschließt.It is particularly advantageous to use a solenoid valve as a control valve use, the movable anchor as a coupling counterpart firmly connected to the end body of the metering valve and whose coil is arranged on the coupling piece. In the Coupling position is that from the coupling device Parts of the coupling piece and the coupling counterpart existing control valve for the metering valve to be opened provided. The dosing valve is switched off by means of a solenoid valve the initial closed position in the delivery position switched by turning on the coil current, whereby the armature is pulled towards the coil and at the same time the Closing body releases the discharge opening of the metering valve. After switching off the coil current, the armature is replaced by a Return spring in the closed position of the metering valve brought back and held there so that the final body closes the dispensing opening.

Der Anker ist kupplungsseitig vorteilhafterweise als eine Platte ausgebildet. Um das Dosierventil von der Schließstellung in die Abgabestellung zu schalten, ist es ausreichend, wenn die beiden Kupplungsteile zum überwiegenden Teil deckungsgleich aneinanderliegen. Hierdurch werden Ungenauigkeiten beim Positionieren des Fahrzeugs beim Kupplungsgegenstück des vorgegebenen Dosierventil ausgeglichen.The anchor is advantageously on the coupling side as one Plate trained. To the metering valve from the It is to switch the closed position to the delivery position sufficient if the two coupling parts predominate The parts are congruent. This will Inaccuracies when positioning the vehicle when Coupling counterpart of the specified metering valve balanced.

Bei einer anderen Ausführungsform ist das Kupplungsgegenstück kupplungsseitig als ein mit einem Hohlraum in der Spule im Kupplungsstück zusammenwirkender Zapfen ausgebildet, so daß in der Kupplungsposition der Kupplungsvorrichtung Anker und Spule eine formschlüssige Loch-Zapfen-Verbindung bilden.In another embodiment, the coupling counterpart coupling side as one with a cavity in the coil in the Coupling cooperating pin formed so that in the coupling position of the coupling device armature and coil form a positive hole-pin connection.

Bei diesen Ausführungsformen werden die Druckluftleitungen von der Schiene zu den Dosierventilen eingespart. Es wird nur noch eine Produktleitung zu jedem Vorratsbehälter benötigt, da das Steuerventil und das Dosierventil beide denselben Ventilkörper haben. Folglich ist der Installationsaufwand erheblich gesenkt. Die Reduzierung der Anzahl der verlegten Leitungen trägt wesentlich zur Übersichtlichkeit in der Dosieranlage bei, da die vorhandenen Leitungen den entsprechenden Dosierventilen direkt zugeordnet werden können.In these embodiments, the compressed air lines of saved the rail to the metering valves. It will only be a product line to each storage container is required because that Control valve and the metering valve both the same valve body to have. As a result, the installation effort is considerable lowered. The reduction in the number of lines laid contributes significantly to the clarity in the dosing system because the existing lines match the corresponding Dosing valves can be assigned directly.

Bei einer weiteren Ausführungsform der Erfindung ist jedem Kupplungsgegenstück auf der Führung, insbesondere einer Schiene, ein Loch und ein Anschluß für über eine Druckleitung mit dem zugehörigen Dosierventil zugeordnet. In dem Kupplungsstück verläuft eine Durchgangsleitung, an die eingangsseitig über einen Anschluß eine Druckleitung zu dem Steuerventil angeschlossen ist. In Kupplungsposition liegen das Loch der Führung und die Öffnung der Durchgangsleitung des Kupplungsstückes deckungsgleich übereinander, so daß eine durchgängige Verbindungsleitung von dem Steuerventil zu dem zugehörigen Dosierventil hergestellt ist. Die Dosierventil sind als von dem Steuerventil pneumatisch schaltbare Dosierzylinder mit angeschlossenen Vorratsbehälter ausgebildet. An der Kolbenstange des Dosierzylinders ist ein die Abgabedüse verschließender oder freigebender Abschlußkörper festgelegt. Das Steuerventil arbeitet als Druckluftventil, das die Flüssigkeitsabgabe des Dosierventiles steuert. In dieser Anordnung sind das Steuerventil und das jeweilige Dosierventil zwei separate, räumlich voneinander getrennte Ventile. In another embodiment of the invention, everyone Coupling counterpart on the guide, especially one Rail, a hole and a connection for a pressure line assigned with the associated metering valve. By doing Coupling piece runs a through line to on the input side via a connection a pressure line to the Control valve is connected. Lie in clutch position the hole of the guide and the opening of the through line of the Coupling piece congruent one above the other, so that a continuous connecting line from the control valve to the associated metering valve is manufactured. The dosing valve are pneumatically switchable from the control valve Dosing cylinder with connected storage container educated. There is a on the piston rod of the dosing cylinder closing or releasing the dispensing nozzle Final body set. The control valve works as Compressed air valve that controls the liquid delivery of the metering valve controls. In this arrangement, the control valve and the each metering valve two separate, spatially apart separate valves.

Bei einer weiteren vorteilhaften Ausführungsform der Kupplungsvorrichtung hat das Kupplungsstück mehrere nebeneinander und/oder hintereinander angeordnete Durchgangsleitungen mit jeweils eingangsseitig einen Anschluß für eine Druckleitung zu einem Steuerventil. In der Kupplungsposition übergreift das Kupplungsstück mehrere ein- oder mehrreihig angeordnete Löcher in der Schiene, so daß die Durchgangsleitungen in dem Kupplungsstück sich an die Löcher der Kupplungsgegenstücke anschließen und jeweils eine durchgehende Verbindungsleitung von den Steuerventilen zu den Dosierventilen entsteht. In einer Position der Kupplungsvorrichtung können durch die aufeinanderfolgende Ansteuerung der entsprechenden Dosierventile mit Hilfe der Steuerventile die Dosierungen verschiedener Flüssigkeitskomponenten vorgenommen werden, ohne daß das Fahrzeug weiterbewegt werden muß. Hierdurch werden die Taktzeiten zwischen den einzelnen Dosierungen verkürzt.In a further advantageous embodiment of the Coupling device, the coupling piece has several arranged side by side and / or one behind the other Through lines, each with a connection on the input side for a pressure line to a control valve. In the Coupling position overlaps the coupling piece several or multiple rows of holes in the rail so that the Through lines in the coupling piece attach themselves to the holes Connect the coupling counterparts and one each continuous connecting line from the control valves to the Dosing valves are created. In a position of Coupling device can by the successive Control of the corresponding metering valves using the Control valves the doses different Liquid components are made without the Vehicle must be moved. This will make the Cycle times between the individual doses reduced.

Die Herstellung der Kupplungsvorrichtung ist einfach und kostengünstig durchführbar ebenso ist die Montage der Kupplungsvorrichtung leicht und sicher vorzunehmen. Weiterhin wird eine einfache, zuverlässige Ansteuerung der einzelnen Dosierventile durch das eine Steuerventil erreicht.The manufacture of the coupling device is simple and The assembly of the is also inexpensive Make coupling device easily and safely. Farther becomes a simple, reliable control of the individual Dosing valves reached through a control valve.

Der wichtigste Vorteil der Erfindung besteht darin, daß alle Dosierventile nur durch ein Steuerventil, vorzugsweise ein Magnetventil, geschaltet werden. Lediglich wenn in derselben Position der Kupplungsvorrichtung auf der Führung mehrere Dosierventile angesteuert werden, sind dem Kupplungsstück mehrere Steuerventile zugeordnet.The main advantage of the invention is that all Dosing valves only by a control valve, preferably a Solenoid valve. Only if in the same Position of the coupling device on the guide several Dosing valves are controlled, the coupling piece assigned several control valves.

In einer Mehrkomponenten-Dosieranlage (10), wie schematisch in Fig. 10 und 11 dargestellt, werden aus vielen verschiedenen Einzelkomponenten bestehende Flüssigkeitsmischungen hergestellt, hierzu sind in Längsrichtung (L) an einem Gestell (50) die Dosierventile (DV) mit ihrer Komponenten-Zuleitung (8) zu einem Vorratsbehälter (VB) von der Flüssigkeitskomponente in Reihe festgelegt. Das Gestell (50) weist eine waagerechte, in Längsrichtung (L) verlaufende Führung (5), vorzugsweise eine Schiene, für ein Fahrzeug (4) einer Kupplungsvorrichtung (1) (vgl. Fig. 1a, 4a, 6a und 9) des Steuerventiles (SV) auf. In der Schiene (5) sind rechtwinklig zur Fahrbahn verlaufende Durchgangsbohrungen (11, 12) als Löcher (11, 12) in vorzugsweise zwei parallelen Reihen gleichmäßig zueinander beabstandet, wobei jede Durchgangsbohrung (11, 12, 17) an der dem Fahrzeug (4) der Kupplungsvorrichtung (1) zugewendeten Kupplungsseite (KS) gegenüberliegenden Längsseite (Anschlußseite) (AS) der Schiene (5) einen Anschluß (6) für eine Flüssigkeits- oder Druckleitung (8, 18) des zugehörigen Dosierventil (DV) hat. An der Kupplungsseite der Schiene (5) ist für jedes Dosierventil (DV) ein mit einem Kupplungsstück (3) der Kupplungsvorrichtung (1) zusammenwirkendes Kupplungsgegenstück (2) vorgesehen.In a multi-component dosing system (10), as schematically in 10 and 11 are shown from many different Individual components of existing liquid mixtures produced, for this are in the longitudinal direction (L) on a frame (50) the dosing valves (DV) with their component supply line (8) to a reservoir (VB) from the liquid component set in series. The frame (50) has a horizontal, guide (5) running in the longitudinal direction (L), preferably a rail, for a vehicle (4) of a coupling device (1) (see FIGS. 1a, 4a, 6a and 9) of the control valve (SV). In the rail (5) are perpendicular to the road Through holes (11, 12) as holes (11, 12) in preferably two parallel rows evenly to each other spaced, each through hole (11, 12, 17) on the the vehicle (4) facing the coupling device (1) Coupling side (KS) opposite long side (Connection side) (AS) of the rail (5) a connection (6) for a liquid or pressure line (8, 18) of the associated Dosing valve (DV). On the coupling side of the rail (5) is for each dosing valve (DV) with a coupling piece (3) the coupling device (1) cooperating Coupling counterpart (2) provided.

Die Kupplungsvorrichtung (1) (gem. Fig. 1a, 4a, 6a sowie 9) besteht aus einem auf der Schiene (5) aufgesetzten Fahrzeug (4) mit einem Hubzylinder (14) als Stellorgan für das Kupplungsstück (3), das beim Ankuppeln von dem Hubzylinder (14) in Richtung der Fahrbahn an das Kupplungsgegenstück (2) des zu schaltenden Dosierventiles (DV)x verfahren wird.The coupling device (1) (according to Fig. 1a, 4a, 6a and 9) consists of a vehicle (4) mounted on the rail (5) with a lifting cylinder (14) as an actuator for the coupling piece (3), which when coupling from the lifting cylinder (14) in the direction of the road to the coupling counterpart (2) of the metering valve (DV) x to be switched.

Das Fahrzeug der Kupplungsvorrichtung (1) ist ein fremd- oder eigenangetriebener Schlitten (4). Dieser Schlitten (4) hat einen nahezu C-förmigen Querschnitt mit innenwandig an den Schenkeln jeweils einer in Achsrichtung verlaufenden Nut als Laufrille für die Schiene (5). Bei auf der Schiene (5) aufgesetztem Schlitten (4) ergibt sich zwischen der Kupplungsseite der Schiene (5) und der Innendeckwandung des Steges von dem C-Profil ein Freiraum, in welchem sich das Kupplungsstück (3) an der in einer Bohrung des Steg gelagerten Kolbenstange (15) des Hubzylinders (14) befindet.The vehicle of the coupling device (1) is a foreign or self-propelled sled (4). This sledge (4) has an almost C-shaped cross-section with inner walls on the Legs each as an axially extending groove Groove for the rail (5). On the rail (5) mounted slide (4) results between the Coupling side of the rail (5) and the inner cover wall of the Bridges of the C-profile a space in which the Coupling piece (3) on the one in a hole in the web Piston rod (15) of the lifting cylinder (14).

Der Hubzylinder (14) ist vorzugsweise pneumatisch betätigt, wozu der Hubzylinder (14) über eine Druckluftleitung (16) an ein Druckluftnetz der Dosieranlage (10) angeschlossen ist. Zum Einnehmen der Kupplungsposition (P1) wird der Hubzylinder (14) mit Druck beaufschlagt, wodurch die Kolbenstange (15) entgegen der Federkraft einer im Kolbenraum des Hubzylinders (14) angeordneten Rückstellfeder (RF) in Arbeitsstellung ausgefahren wird, um das Kupplungsstück (3) zur Anlage mit dem Kupplungsgegenstück (2) zu bringen. In Kupplungsposition (P1) verbinden das Kupplungsstück (3) und Kupplungsgegenstück (2) das Steuerventil (SV) mit dem jeweiligen Dosierventil (DVX) um es von der Schließstellung (S0) in Abgabestellung (S1) zu schalten. In Entkupplungsposition (P0) der Kupplungsvorrichtung (1) bewirkt die Rückstellfeder des Hubzylinders (14), daß derselbe in seiner Endstellung gehalten wird, in der das Kupplungsstück (3) zu dem Kupplungsgegenstück (2) beabstandet ist. Die Kupplungsvorrichtung (1) ist in dieser Position (P0) entlang der Schiene (5) zu einem anderen Ort verfahrbar, um die Dosierung einer anderen Flüssigkeitskomponente mit Hilfe eines weiteren Dosierventiles (DVx) vornehmen zu können.The lifting cylinder (14) is preferably operated pneumatically, for which purpose the lifting cylinder (14) is connected to a compressed air network of the metering system (10) via a compressed air line (16). To take up the coupling position (P1), the lifting cylinder (14) is pressurized, whereby the piston rod (15) is extended against the spring force of a return spring (RF) arranged in the piston chamber of the lifting cylinder (14) in the working position in order to move the coupling piece (3). bring it into contact with the coupling counterpart (2). In coupling position (P1), the coupling piece (3) and coupling counterpart (2) connect the control valve (SV) to the respective metering valve (DV X ) in order to switch it from the closed position (S0) to the delivery position (S1). In the uncoupling position (P0) of the coupling device (1), the return spring of the lifting cylinder (14) causes it to be held in its end position in which the coupling piece (3) is spaced from the coupling counterpart (2). In this position (P0) the coupling device (1) can be moved along the rail (5) to another location in order to be able to dose another liquid component with the aid of a further metering valve (DV x ).

Die verschiedenen Flüssigkeitskomponenten werden jeweils über das angekoppelte Dosierventil (DV)x in einen unterhalb der Dosierventile (DV) auf einem Wägefahrzeug (20) positionierten Mischbehälter (MB) kontrolliert abgegeben. Vorzugsweise haben das Wägefahrzeug (20) und der Schlitten (5) eine gemeinsame Führung, dann ist der Schlitten (5) starr mit dem Wägefahrzeug (20) verbunden. Selbstverständlich kann auch jedes der beiden Fahrzeug (4, 20) einen eigenen Antrieb aufweisen.The various liquid components are dispensed in a controlled manner via the coupled metering valve (DV) x into a mixing container (MB) positioned below the metering valves (DV) on a weighing vehicle (20). The weighing vehicle (20) and the slide (5) preferably have a common guide, then the slide (5) is rigidly connected to the weighing vehicle (20). Of course, each of the two vehicles (4, 20) can also have its own drive.

In Fig. 5 ist die getrennte Verfahrbarkeit und die starre Verbindung (51) zwischen Schlitten (4) und Wägefahrzeug (20) zum gemeinsamen Fahren in strich-punktierten Linien gezeigt.In Fig. 5 is the separate travel and the rigid Connection (51) between slide (4) and weighing vehicle (20) shown for driving together in dash-dotted lines.

Zur Abgabe der einzelnen Flüssigkeitskomponenten nach dem gewählten Rezepturprogramm wird das Wägefahrzeug (20) mit dem Mischbehälter (MB) stets an dem Ort des Gestells (50) positioniert, an welchem sich die Abgabeöffnung des Dosierventiles (DVX) befindet, das als nächstes geschalten wird. Die verschiedenen Dosierventile (DV) sind abhängig von der Ausführungsform der Kupplungsvorrichtung (1), vorzugsweise linear oder kreisförmig, als platzsparende Einheiten in Längsrichtung (L) des Gestells (50) angeordnet, wobei es zweckmäßig ist, den Abstand zwischen den einzelnen Dosierventilen (DV) gering zu halten, um in der gleichen Position des Wägefahrzeugs (20) mit Mischbehälter (MB) mehrere Flüssigkeitskomponenten nacheinander zu dosieren, ohne das Wägefahrzeug (20) zu verfahren.To dispense the individual liquid components according to the selected recipe program, the weighing vehicle (20) with the mixing container (MB) is always positioned at the location of the frame (50) at which the dispensing opening of the metering valve (DV X ) is located, which is then switched on , Depending on the embodiment of the coupling device (1), preferably linear or circular, the various metering valves (DV) are arranged as space-saving units in the longitudinal direction (L) of the frame (50), it being expedient to determine the distance between the individual metering valves (DV ) to be kept low in order to meter several liquid components in succession in the same position of the weighing vehicle (20) with mixing container (MB) without moving the weighing vehicle (20).

Die in den Fig. 1 bis 6 gezeigten Kupplungsvorrichtungen (1) für das Steuerventil (SV) weisen als Kupplungsstück (3) eine Spule (S) auf, die an dem kupplungsseitigen Ende der Kolbenstange (15) des Hubzylinders (14) festgelegt ist. Die Dosierventile (DV) sind auf einer dem Schlitten (4) zugewandten Längsseite (Kupplungsseite) (KS) der Schiene (5) einreihig angeordnet, wobei die Kupplungsgegenstücke (2) jeweils einen mit der Spule (S) zusammenwirkenden Anker (A) aufweisen, der mit dem Abschlußkörper (AK) des dem Kupplungsgegenstück (2) zugehörigen Dosierventiles (DV) verbunden sind. In Kupplungsposition (P1) stellt die Kupplungsvorrichtung (1) aus dem Anker (A) und der Spule (S) ein Steuerventil (SV) als Schaltelement für das zu öffnende Dosierventil (DVx) in einer Mehrkomponenten-Dosieranlage (10) in Form eines Magnetventiles (MV) her, beide Ventile (SV, DVX) haben einen gemeinsamen, flüssigkeitsdurchströmten Ventilkörper (VK). In dem Magnetventil (MV) sind gleichzeitig die Funktionen des Steuerventiles (SV) und eines Dosierventiles (DVx) vereint.The coupling devices (1) for the control valve (SV) shown in FIGS. 1 to 6 have as the coupling piece (3) a coil (S) which is fixed to the coupling-side end of the piston rod (15) of the lifting cylinder (14). The metering valves (DV) are arranged in a single row on a longitudinal side (coupling side) (KS) of the rail (5) facing the carriage (4), the coupling counterparts (2) each having an armature (A) which interacts with the coil (S), which are connected to the closing body (AK) of the metering valve (DV) associated with the coupling counterpart (2). In the coupling position (P1), the coupling device (1) from the armature (A) and the coil (S) provides a control valve (SV) as a switching element for the metering valve (DV x ) to be opened in a multi-component metering system (10) in the form of a Solenoid valves (MV), both valves (SV, DV X ) have a common, liquid-flowed valve body (VK). The functions of the control valve (SV) and a metering valve (DV x ) are combined in the solenoid valve (MV).

Die Schiene (5) hat pro Dosierventil (DV) paarweise, nebeneinander angeordnete Durchgangsbohrungen (11, 12) mit je einem Anschluß (6, 7) für Flüssigkeitsleitungen (8, 9), nämlich für eine eingangsseitige Komponenten-Zuleitung (8) vom Vorratsbehälter (VB) zum Ventilkörper (VK) und für eine ausgangsseitige Komponenten-Ableitungen (9) vom Ventilkörper (VK) in den Mischbehälter (MB). The rail (5) has in pairs for each metering valve (DV), side by side through holes (11, 12) each with a connection (6, 7) for liquid lines (8, 9), namely for an input-side component feed line (8) from Reservoir (VB) to the valve body (VK) and for one component derivatives on the output side (9) from the valve body (VK) in the mixing container (MB).

Die Dosierventile (DV) sind als Tellerventile ausgebildet, wobei der von einem Ventilteller gebildete Abschlußkörper (AK) schienenseitig an dem in dem Ventilkörper (VK) beweglich geführten Anker (A) angeordnet ist. In der Schließstellung (S0) des Dosierventiles (DV) preßt eine Rückstellfeder den Abschlußkörper (AK) gegen die Öffnung der Komponenten-Ableitung (9) und sperrt diese gegen den Flüssigkeitsstrom. In Abgabestellung (S1) des Dosierventiles (DVX)sind die beiden Komponenten-Leitungen (8, 9) über den Ventilkörper (VK) durchgängig miteinanderverbunden.The metering valves (DV) are designed as plate valves, the closing body (AK) formed by a valve plate being arranged on the rail side on the armature (A) movably guided in the valve body (VK). In the closed position (S0) of the metering valve (DV), a return spring presses the closing body (AK) against the opening of the component discharge line (9) and blocks it against the liquid flow. In the delivery position (S1) of the metering valve (DV X ), the two component lines (8, 9) are continuously connected to each other via the valve body (VK).

Die Fig. 1a, 1b und 2 sowie Fig. 4a und 4b zeigen das ausgewählte Dosierventil (DVx) in Schließstellung (S0), alle übrigen Dosierventile (DV) in der Dosieranlage (10) sind ebenfalls geschlossen, weil sich die Kupplungsvorrichtung (1) in Entkupplungsposition (P0) befindet sich und das Steuerventil (SV) für die Dosierventile (DV) in seine einzelnen Bestandteile (S, A) zerlegt ist. Der Anker (A) des Kupplungsgegenstückes (2) ist zu der Spule (S) des Kupplungsstückes (3) beabstandet. Nun kann entweder der Abgabevorgang durch Kuppeln der Kupplungsvorrichtung (1) und Schalten des Dosierventiles (DVx) eingeleitet werden oder der Schlitten (4) mit dem Kupplungsstück (3) wird beim nächsten, zu schaltenden Dosierventil (DV) positioniert.1a, 1b and 2 and FIGS. 4a and 4b show the selected metering valve (DV x ) in the closed position (S0), all other metering valves (DV) in the metering system (10) are also closed because the coupling device (1st ) is in the uncoupling position (P0) and the control valve (SV) for the metering valves (DV) is broken down into its individual components (S, A). The armature (A) of the coupling counterpart (2) is spaced from the coil (S) of the coupling piece (3). Now either the delivery process can be initiated by coupling the coupling device (1) and switching the metering valve (DV x ) or the slide (4) with the coupling piece (3) is positioned at the next metering valve (DV) to be switched.

Die Fig. 3 sowie Fig. 5 zeigen die Kupplungsvorrichtung (1) in Kupplungsposition (P1) und das nach dem Rezepturprogramm ausgewählte Dosierventil (DVx) in Abgabestellung (S1). Der Hubzylinder (14) ist in Arbeitsstellung ausgefahren, so daß das Kupplungsstück (3) mit der Spule (S) und das Kupplungsgegenstück (3) mit dem innenliegenden Anker (A) zusammenwirkt. Erst jetzt ist das Steuerventil (SV) in Form eines elektrisch betätigten Magnetventil (MV) zusammengesetzt, so daß das zugeordnete Dosierventil (DVX) zum Dosieren und Mischen der gewählten Komponente freigeschaltet werden kann, um die Flüssigkeit über die Komponenten-Zuleitung (8) aus einem vorgeschalteten Vorratsbehälter (VB) nach dem Passieren des Ventilkörpers (VK) über die Komponenten-Ableitung (9) an einen unterhalb des Dosierventiles (DVx) positionierten Mischbehälter (MB), wie Gebinde, abzugeben. Beim Schalten des Dosierventiles (DVx) wird das Steuerventil (SV) von einem elektrischen Steuersignals direkt geschaltet. Nach Einschalten des Spulenstromes wird der bewegliche Anker (A) in Richtung Spule (S) gezogen, wodurch im Ventilkörper (VK) der Abschlußkörper (AK) von seinem Ventilsitz (VS) abgehoben wird. Das Dosierventil (DVx) befindet sich in Abgabestellung (S1).3 and 5 show the coupling device (1) in the coupling position (P1) and the metering valve (DV x ) selected according to the recipe program in the delivery position (S1). The lifting cylinder (14) is extended in the working position so that the coupling piece (3) with the coil (S) and the coupling counterpart (3) cooperate with the inner armature (A). Only now is the control valve (SV) assembled in the form of an electrically operated solenoid valve (MV) so that the associated metering valve (DV X ) for metering and mixing the selected component can be activated in order to supply the liquid via the component supply line (8) dispense from an upstream storage container (VB) after passing through the valve body (VK) via the component discharge line (9) to a mixing container (MB), such as a container, positioned below the metering valve (DV x ). When the metering valve (DV x ) is switched, the control valve (SV) is switched directly by an electrical control signal. After switching on the coil current, the movable armature (A) is pulled in the direction of the coil (S), as a result of which the closing body (AK) is lifted from its valve seat (VS) in the valve body (VK). The dosing valve (DV x ) is in the delivery position (S1).

Fig. 1a, 1b, 2 und 3 zeigen eine erste Ausführungsform der Kupplungsvorrichtung (1) deren Kupplungsstück (3) und Kupplungsgegenstück (2) kupplungsseitig eine ebene Oberfläche besitzen, die in der Kupplungsposition (P1) aneinander bzw. aufeinander liegen. Zu dem in Fig. 2 und 3 detailliert dargestellten Kupplungsgegenstück (2) gehört jeweils ein mehrteiliges, antimagnetisches Gehäuse, welches aus einem Deckel (21) und einem in dem Ventilkörper (VK) abgedichtet, eingesetzten Unterteil (22) mit einer innenseitigen axialen Führung für den Anker (A) zusammengesetzt ist.
