Roboter für die Reparatur und Erneuerung von Leitungen mit auswechselbaren Behältern für das Ausbesserungsmaterial sind seit der EP-B1 0 211 825 bekannt. Erst damit wurde die praktisch kontinuierliche Ausbesserungsarbeit vor Ort ermöglicht.Robots for the repair and renewal of lines with exchangeable containers for the repair material have been known since EP-B1 0 211 825. Only then was the practically continuous repair work on site made possible.
Der Behälter gemäss dieser EP-B1, wie auch die verschiedenen darin enthaltenen Ausbesserungsmaterialien, sind in der Schrift nicht weiter spezifiziert.The container according to this EP-B1, as well as the various repair materials contained therein, are not further specified in the document.
Andererseits sind Mehrkomponentenbehälter für Harze u.ä. auch aus der Patentliteratur bekannt:
So lehrt und beansprucht die CH-A5 659 629 einen Zweikammer-Behälter für pastöse Massen, bestehend aus einem Gehäuse und einer Ausdrückanordnung, wobei das Gehäuse durch eine in Längsrichtung angeordnete Trennwand in zwei separate Kammern unterteilt ist. Am oberen Ende einer jeden Kammer ist jeweils eine Auslassöffnung vorgesehen, die durch einen quer zur Längsrichtung verschiebbaren Absperrschieber verschliessbar ist. In jeder Kammer ist zudem ein Kolben vorgesehen, der in Richtung zur Auslassöffnung verschiebbar ist.On the other hand, multi-component containers for resins and the like. also known from the patent literature:
For example, CH-A5 659 629 teaches and claims a two-chamber container for pasty masses, consisting of a housing and an ejection arrangement, the housing being divided into two separate chambers by a longitudinally arranged partition. At the upper end of each chamber there is an outlet opening through a gate valve which can be moved transversely to the longitudinal direction is lockable. A piston is also provided in each chamber and can be displaced in the direction of the outlet opening.
Eine Verwendung dieses Behälters auf irgenwelchen Automaten ist nicht vorgesehen, und die entsprechenden ausformungsmässigen Aenderungen sind nicht angedeutet. Eine Mischspitze wird im Text genannt, aber weder dort noch in der Zeichnung spezifiziert.It is not intended to use this container on any machine, and the corresponding changes in terms of shape are not indicated. A mixed tip is mentioned in the text, but is neither specified there nor in the drawing.
Der Materialbehälter gemäss der US-A 4 811 549 ist, gemäss den Figuren 4 und 5, ebenfalls ein Zweikammerbehälter für Zweikomponenten-Harze. Gemäss dem zu den genannten Figuren gehörenden Beispiel 5 wird, vor der Verwendung des Harzes, die Trennmembrane entfernt; eine diskontinuierliche Abgabe des Harzes wird dadurch praktisch verunmöglicht.According to FIGS. 4 and 5, the material container according to US Pat. No. 4,811,549 is also a two-chamber container for two-component resins. According to Example 5 belonging to the figures mentioned, the separating membrane is removed before the resin is used; discontinuous dispensing of the resin is practically impossible.
Von einer Verwendung dieses Materialbehälters in Applikationsvorrichtungen wird, aufgrund seiner Ausformung, zudem weggelehrt.Due to its shape, use of this material container in application devices is also taught away.
Schliesslich beschreibt die US-A 4 771 919 eine auf derartige Behälter aufschraubbare Mischspitze. Die gesamte Anordnung kann offensichtlich nicht auf Geräten u.a. angebracht werden (u.a. sind weder die vordere Ausbildungsform der Mischspitze noch die im Ausstoss-Sinn hintere Frontseite des Behälters spezifiziert oder beispielhaft erläutert).Finally, US Pat. No. 4,771,919 describes a mixing tip that can be screwed onto such containers. The entire arrangement obviously cannot be used on devices etc. are attached (among other things, neither the front design of the mixing tip nor the front of the container in the sense of ejection are specified or exemplified).
Auch für den Fachmann nicht ohne weiteres voraussehbar kann nun die oben spezifizerte Aufgabe mit dem erfindungsgemässen Wechselbehälter in praktisch genügendem Applikationsumfang gelöst werden.Even for the person skilled in the art, it is not readily foreseeable that the task specified above can now be achieved with the swap body according to the invention in practically sufficient scope of application.
Der erfindungsgemässe, auf Applikationsgeräten, Fahrzeugen, Robotern u.ä. anbringbare Wechselbehälter zur Aufnahme, Vermischung bzw. Homogenisierung und auch diskontinuierlichen Abgabe von ein- oder mehrkomponentigen fluiden Beschichtungs- und/oder Ausbesserungsmaterialien ist dadurch gekennzeichnet, dass der Behälter, als Hauptkomponenten, einen Aussenbehälter für das Beschichtungs- und/oder Ausbesserungsmaterial sowie einen darin einsetz- und daraus wieder entnehmbaren Misch-Einsatz aufweist, wobei, bei im Behälter eingesetztem Misch-Einsatz, die beiden Frontseiten des Wechselbehälters so ausgebildet sind, dass sie mit fixierenden Gegenflächen in Kontakt gebracht werden können.The inventive, on application devices, vehicles, robots, etc. Attachable interchangeable containers for receiving, mixing or homogenizing and also discontinuous dispensing of one- or multi-component fluid coating and / or repair materials is characterized in that the container, as main components, has an outer container for the coating and / or Repair material as well as a mixing insert which can be inserted and removed therefrom, wherein, when the mixing insert is inserted in the container, the two front sides of the interchangeable container are designed such that they can be brought into contact with fixing counter surfaces.
Dieser Wechselbehälter ist vorteilhafterweise so ausgebildet, dass der Aussenbehälter kreiszylidrisch ausgebildet ist und in seinem Innern einen oder mehrere ko- oder ex-axial angeordnete zylindrische Teilbehälter aufweist. Speziell kann ein zentraler axialer Teil-Behälter als Durchführung für eine Stange, ein Rohr, Leitungen u.ä. vorgesehen ist.This interchangeable container is advantageously designed such that the outer container is circular-cylindrical and has one or more co-or ex-axially arranged cylindrical partial containers in its interior. In particular, a central axial partial container can be used as a feedthrough for a rod, a pipe, lines and the like. is provided.
Alle Material enthaltenden Behälter sind dabei im Ausstoss-Sinn hinten durch mechanisch oder hydraulisch bewegbare Kolben oder durch festsitzende Verschlüsse abgedichtet. Bei festen Verschlüssen kann der Misch-Einsatz ein Förderaggregat wie eine Kreisel-, Zahnrad-, Kreiskolben- oder Spindelpumpe enthalten, welches Aggregat das Beschichtungs- und/oder Ausbesserungsmaterial durch den Misch-Einsatz fördert.All containers containing material are sealed at the rear in the sense of ejection by mechanically or hydraulically movable pistons or by fixed closures. In the case of fixed closures, the mixing insert can contain a delivery unit such as a centrifugal, gear, rotary piston or spindle pump, which unit conveys the coating and / or repair material through the mixing insert.
Ein passiver Misch-Einsatz besteht z.B. aus mehreren Schichten, wobei im Ausstoss-Sinn hinten eine kompakte, nur Durchführungsbohrungen aufweisende Schicht vorgesehen ist, wobei die folgenden Schichten eine nach vorne feiner werdende Sinter- bzw. Füllkörper-Struktur aufweisen und wobei die vorderste Schicht eine der Gegenfläche etwa entsprechende Austrittsöffnung aufweist. Ein aktiver Misch-Einsatz ist z.B. entweder ein mechanisch, hydraulisch oder elektrisch mittels einer(s) durch den zentralen Teilbehälter durchgeführten Stange, Rohres bzw. Leitung bewegter Mischkopf, Schaufel- oder Schneckenmischer, gegebenenfalls mit Antriebsmotor, oder ein Thermokopf zwecks Lösung von festen Härtern in EinKomponenten-Epoxidharzmischungen vor der Abgabe.A passive mixed use exists e.g. consisting of several layers, a compact layer with only through-holes being provided at the rear in the sense of ejection, the following layers having a sintered or filler structure which becomes finer towards the front, and the front layer having an outlet opening approximately corresponding to the counter surface. An active mixed use is e.g. either a mechanical, hydraulic or electrical mixing head, vane or screw mixer, possibly with a drive motor, which is moved through a rod, pipe or line through the central sub-container, or a thermal head for the solution of solid hardeners in one-component epoxy resin mixtures before delivery .
Der Misch-Einsatz kann grundsätzlich sowohl Konstruktionselemente der passiven wie auch der aktiven Misch-Einsätze aufweisen.The mixed use can basically be both construction elements of passive as well as active mixing inserts.
Eingesetzt wird der erfindungsgemässe Wechselbehälter so, dass vorerst - gegebenenfalls nach Entfernung einer Schutzabdeckung über dem Harz - der Misch-Einsatz vorn in den das bzw. die Material(ien) enthaltenden Wechselbehälter eingesetzt wird und dass, anschliessend, der Wechselbehälter in die dafür vorgesehene Aufnahmevorrichtung des Gerätes eingesetzt wird, wobei die hintere Behälter-Frontseite dichtend an die fixierende Gegenfläche mit der Druckluftdurchführung und die vordere Behälter-Frontseite dichtend an die Gegenfläche mit der Material- Austrittsöffnung angebracht wird.The interchangeable container according to the invention is used in such a way that the mixing insert is inserted in the front into the interchangeable container containing the material (s), and then, afterwards, the interchangeable container is placed in the receptacle provided for this purpose, possibly after removing a protective cover from the resin of the device is used, the rear front of the container sealingly attached to the fixing counter surface with the compressed air duct and the front front of the container sealingly attached to the counter surface with the material outlet opening.
In Analogie dazu wird, bei einem Misch-Einsatz mit Förderaggregat, der Misch-Einsatz vorn in den das bzw. die Material(ien) enthaltenden Wechselbehälter eingesetzt, die Energiezufuhr zum Aggregat angeschlossen und der Wechselbehälter dichtend an die Gegenflächen angebracht.In analogy to this, in the case of a mixed insert with conveying unit, the front mixed insert is inserted into the swap body containing the material (s), the energy supply to the unit is connected and the swap body is sealingly attached to the counter surfaces.
Bei der Verwendung eines aktiven Misch-Einsatzes im erfindungsgemässen Wechselbehälter wird so vorgegangen, dass vorerst der das bzw. die Material(ien) enthaltende Wechselbehälter unter Einführung der Stange, des Rohres oder der Leitung(en) in den zentralen, koaxialen Teilbehälter in die Aufnahmevorrichtung eingesetzt wird, dass, anschliessend, der Misch-Einsatz, gegebenenfalls unter Einhaken und/oder Befestigen und/oder Anschluss an Stange/Rohr/Leitung, in den Behälter eingesetzt wird, und dass, abschliessend, der Wechselbehälter dichtend an die fixierenden Gegenflächen angebracht wird.When using an active mixing insert in the swap body according to the invention, the procedure is such that the swap body containing the material (s) is initially inserted into the receiving device by introducing the rod, tube or line (s) into the central, coaxial sub-tank It is used that the mixing insert is then inserted into the container, possibly with hooking and / or fastening and / or connection to a rod / pipe / line, and that, finally, the interchangeable container is sealingly attached to the fixing counter surfaces .
Bei der Verwendung von Wechselbehältern mit gleitenden Abdichtungen kann das die Kolben bewegende Druckgas entweder ein von aussen über Schläuche oder ein mittels eines Kompressores im Gerät generiertes sein.When using interchangeable containers with sliding seals, the compressed gas moving the pistons can either be one from the outside via hoses or one generated by means of a compressor in the device.
Die Erfindung wird nun anhand der beiliegenden Figuren 1 bis und mit 3 sowie der anschliessenden, schriftlichen Ausführungen beispielhaft erläutert:The invention will now be described with reference to the accompanying figures 1 to and with 3 and the subsequent written explanations as an example:
Dabei zeigen:
- die Figur 1 die allgemeine Anordnung der Hauptkomponenten des erfindungsgemässen Wechselbehälters,
- die Figur 2 die Anordnung weiterer zylindrischer Materialbehälter und
- die Figur 3 einen passiven Misch-Einsatz.
- 1 shows the general arrangement of the main components of the swap body according to the invention,
- 2 shows the arrangement of further cylindrical material containers and
- 3 shows a passive mixing insert.
Alle Figuren sind so dargestellt, dass das linke Ende mit im Ausstoss-Sinn "hinten" und das rechte Ende mit im Ausstoss-Sinn "vorn" gleichzustellen sind.All figures are shown in such a way that the left end is to be equated with "rear" in the sense of ejection and the right end with "front" in the sense of ejection.
In Figur 1 ist mit 1.1 der zylindrische Aussenbehälter bezeichnet, Er besteht aus Metall oder aus - gegebenenfalls armiertem - Kunststoff. Zwecks Verhütung der Haftung des Ausbesserungsmaterials an der Innenwand kann diese speziell vorbehandelt oder beschichtet sein.In FIG. 1, 1.1 denotes the cylindrical outer container. It is made of metal or - optionally reinforced - plastic. To prevent the repair material from adhering to the inner wall, it can be specially pretreated or coated.
Das Ausbesserungsmaterial 1.2 selbst kann ein einkomponentiges sein; technisch wichtiger sind jedoch die zweikomponentigen. Diese gehören zur Gruppe der strukturellen Klebstoffe; typische Vertreter sind Phenolharze, Polyurethane, ungesättigte Polyester und Epoxidharze.The repair material 1.2 itself can be a one-component; However, the two-component are technically more important. These belong to the group of structural adhesives; typical representatives are phenolic resins, polyurethanes, unsaturated polyesters and epoxy resins.
Beim Einsatz als Ausbesserungsmaterial werden Epoxidharze normal erweise mit Aminen gehärtet. Die Härtungsreaktion verläuft unter Bildung von Hxdroxylgruppen, die über Wasserstoffbrückenbindungen für eine gute Haftung insbesondere auf Metallen und Bau-Werkstoffen sorgen. Als Härter werden je nach den gewünschten Verarbeitungs- und Endeigenschaften aliphatische, cycloaliphatische, aromatische Amine, Polyaminoamide oder deren Abmischungen eingesetzt. Polyaminoamide sind langkettige polymere Verbindungen, die flexibilisierend wirken. Sie sind kalthärtend und verlängern die Gebrauchsdauer sowie die Härtungszeit.When used as a repair material, epoxy resins are normally cured with amines. The hardening reaction proceeds with the formation of hydroxyl groups, which ensure good adhesion, in particular on metals and building materials, via hydrogen bonds. Depending on the desired processing and end properties, aliphatic, cycloaliphatic, aromatic amines, polyaminoamides or their mixtures are used as hardeners. Polyaminoamides are long-chain polymeric compounds that have a flexibilizing effect. They are cold curing and extend the service life as well as the curing time.
Die Standardsysteme der Epoxidharze sind flüssige oder durch den Einsatz von Füllstoffen pastös eingestellte Zweikomponentensysteme. Die Verarbeitungseigenschaften beider Komponenten sind aufeinander abgestimmt. Die Fliesseigenschaften der Harz- und Härterkomponente sind ähnlich, um Fehler bei der Dosierung und anschliessenden Durchmischung zu vermeiden.The standard systems of epoxy resins are liquid or two-component systems that are pasty due to the use of fillers. The processing properties of both components are coordinated. The flow properties of the resin and hardener components are similar in order to avoid errors in the dosage and subsequent mixing.
Das Dosieren, Mischen und Applizieren kann von Hand vorgenommen oder maschinell durchgeführt werden.Dosing, mixing and application can be done by hand or by machine.
Je nach der Grösse der auszubessernden Stelle und der Mischviskosität wird das Material mit einem Spatel, Zahnspachtel oder Rakel aufgetragen, aufgegossen oder eingewalzt. 2-Komponenten-Systeme sind kalt- bis warmhärtend. Die Härtungsdauer beträgt je nach System ca. 24 Stunden bei 20oC und wenige Minuten bei 120oC. Je höher die Härtungstemperatur, desto besser ist die erreichte Warmfestigkeit des Systems.Depending on the size of the area to be repaired and the mixed viscosity, the material is applied with a spatula, toothed spatula or squeegee, poured on or rolled on. 2-component systems are cold to warm curing. Depending on the system, the curing time is approx. 24 hours at 20 o C and a few minutes at 120 o C. The higher the curing temperature, the better the heat resistance achieved by the system.
Epoxidharze in Form von Einkomponenten-Systemen werden dann eingesetzt, wenn nach der Aushärtung hohe Festigkeiten bei Temperaturen über 100oC und eine einfache Verarbeitbarkeit gefordert sind. Bei solchen Systemen liegen Harz und Härter nebeneinander in der Mischung vor. Der Härter ist bei Raumtemperatur fest und unlöslich. Erst durch Zufuhr von Wärme geht er in Lösung und leitet so die Härtungsreaktion ein. Die Lagerstabilität ist je nach System auf einen Zeitraum von einigen Wochen bis zu einem Jahr begrenzt.Epoxy resins in the form of one-component systems are used when, after curing, high strengths at temperatures above 100 o C and easy processing are required. In such systems, resin and hardener are present side by side in the mixture. The hardener is solid and insoluble at room temperature. Only when heat is added does it go into solution and thus initiate the hardening reaction. Depending on the system, the storage stability is limited to a period of a few weeks to a year.
