Description

Die Erfindung bezieht sich auf eine Reinigungsvorrichtung für auf Förderbahnen fortbewegte Teile gemäß Oberbegriff des Anspruchs 1 bzw. des nebengeordneten Anspruchs 8; eine derartige Vorrichtung ist durch die EP-A 0 110 525 bekannt.The invention relates to a cleaning device for moving parts on conveyor tracks according to the preamble of claim 1 and the independent claim 8; such a device is known from EP-A 0 110 525.

Bei der durch die EP-A 0 110 525 bekannten Vorrichtung zur Reinigung von auf einem Förderband transportierten verschmutzten Teilen werden diese an ihrem einen Ende vom Arm eines gesonderten, außerhalb von Förderbahn und Waschgerät angeordneten Roboters ergriffen, durch eine seitliche Beschickungsöffnung in den Waschbehälter zwischen darin oberhalb und unterhalb angeordnete Spritzdüsen gebracht und vom Roboter während des anschließenden Waschvorganges in Rotation gehalten.In the device known from EP-A 0 110 525 for cleaning soiled parts transported on a conveyor belt, they are gripped at one end by the arm of a separate robot arranged outside the conveyor track and washing device, through a lateral loading opening in the washing container between them Spray nozzles arranged above and below and kept in rotation by the robot during the subsequent washing process.

Durch die US-A 3 075 215 ist eine Geschirrspülmaschine bekannt, bei der in einer Waschkammer Tablette derart drehbar gelagert sind, daß sie zunächst von oben her mit Geschirrteilen belegt und dann um 180° gedreht und dadurch die Geschirrteile gegen den Strahl von im Unterteil der Waschkammer angeordnete Sprühköpfe gerichtet werden können.From US-A 3 075 215 a dishwasher is known in which tablets are rotatably mounted in a washing chamber in such a way that they are first loaded with dishes from above and then rotated through 180 ° and thereby the dishes against the jet of in the lower part of the Wash chamber arranged spray heads can be directed.

Bei einem aus der DE-B2 2 312 682 bekannten Waschgerät ist zum Waschen von schweren Waschgütem an der Tür des Waschgerätes ein Waschgutträger angebracht. Das Beladen erfolgt bei soweit ausgeschwenktem Waschgutträger und abgesenkter Türe, daß der Waschgutträger mit dem Boden niveaugleich liegt und ein mit dem Waschgut beladenes Transportgerät aufgeschoben werden kann. Nach Schließen der Türe wird diese samt Waschgutträger und Transportgerät angehoben und in die Wascheinrichtung hineingeschwenkt. In der Waschkammer sind zur Reinigung des Waschgutes mehrere Spritzdüsen vorgesehen, die in einem vertikalen Düsenträger seitlich des Transportgerätes und damit des Waschgutes angeordnet sind.In a washing device known from DE-B2 2 312 682, a laundry support is attached to the door of the washing device for washing heavy laundry items. Loading takes place with the laundry carrier swung out and the door lowered so that the laundry carrier lies at the same level with the floor and a transport device loaded with the laundry can be pushed on. After closing the door, it is lifted together with the laundry carrier and transport device and swiveled into the washing device. In the washing chamber, several spray nozzles are provided for cleaning the items to be washed, which are arranged in a vertical nozzle holder to the side of the transport device and thus of the items to be washed.

Der Erfindung liegt die Aufgabe zugrunde, eine Reinigung von Werkstückträgern zu ermöglichen, bei der mit geringem Aufwand and Zeit und Material auch schwere bzw. aufgrund von Verkrallung oder starker Fettverschmutzung am Werkstückträger intensiv haftende Schmutzpartikel entfernt werden können. Eine derartige Problemstellung ergibt sich insbesondere bei einer automatischen Elektromotorenmontage, bei der die Werkstückträger durch fettbehafteten Metallabrieb, insbesondere Späne, verschmutzt werden; dadurch besteht die Gefahr, daß erste Motorbauteile z.B. nicht plan auf dem Werkstückträger zur Auflage kommen und dementsprechend mit weiteren hinzugefügten Motorbauteilen nicht paßgenau zusammenmontiert werden können.The invention has for its object to enable cleaning of workpiece carriers, in which heavy dirt particles or particles adhering to the workpiece carrier due to claws or heavy grease contamination can be removed with little effort and time and material. Such a problem arises in particular in the case of automatic electric motor assembly, in which the workpiece carriers are contaminated by greasy metal abrasion, in particular chips; this creates the risk that the first engine components e.g. do not come to rest flat on the workpiece carrier and accordingly cannot be fitted together with other added motor components.

Die Lösung dieser Aufgabe ist bei einer Reinigungsvorrichtung der eingangs genannten Art durch die Lehre des Anspruchs 1 bzw. des Anspruchs 8 möglich. Die erfindungsgemäße Vorrichtung erlaubt in einfacher Weise, insbesondere auch als Nachrüstung für bereits installierte Montagesysteme, eine vollständige und schnelle Reinigung der Werkzeugträger, wobei durch die Ablage der Werkstückträger auf einem Waschgutträger die Beschickungsvorrichtung nach dieser Ablage während des Waschvorganges für weitere Handhabungen zur Verfügung steht.This object can be achieved in a cleaning device of the type mentioned at the outset by the teaching of claim 1 or claim 8. The device according to the invention allows, in a simple manner, in particular also as a retrofit for already installed mounting systems, a complete and quick cleaning of the tool carriers, the loading device being available for further handling after the storage of the workpiece carriers on a laundry carrier after this storage.

Zur aufwandsarmen und einfachen Halterung der Werkstückträger auf dem Waschgutträger sind auf dessen Oberseite winkelförmige, das hineingebrachte Waschgut mit einem Schenkel übergreifende Halterungsschienen befestigt.For low-effort and simple mounting of the workpiece carrier on the laundry carrier, angular mounting rails are attached to the upper side of the laundry which are brought in with one leg.

Wird zwischen den Waschgutträgem und der umgebenden Wandung der Waschkammer ein Dichtmittel vorgesehen, so kann Flüssigkeitsverlust und Geruchsbelästigung mit Sicherheit vermieden werden; außerdem kann auf einen gesonderten Türverschluß der Beschickungsöffnung verzichtet werden, was einer leichten sowie schnellen Be- und Entladung des Waschgerätes zugutekommt.If a sealant is provided between the items to be washed and the surrounding wall of the washing chamber, liquid loss and unpleasant smells can be avoided with certainty; in addition, a separate door lock of the loading opening can be dispensed with, which benefits easy and quick loading and unloading of the washing device.

Durch Verwendung eines zentralen Sprühkopfes ergibt sich eine besonders einfache und trotzdem sehr wirkungsvolle Sprühvorrichtung. Ein Filter unterhalb der Sprühvorrichtung sorgt für das Aussondern unlöslicher Schmutzpartikel aus der umgepumpten Waschflüssigkeit. Das Reinigen dieses Filters wird erheblich erleichtert, wenn dieser als von außen in die Reinigungsvorrichtung nach Art einer Schublade einschiebbarer Korb ausgebildet ist.Using a central spray head results in a particularly simple and yet very effective spray device. A filter below the spray device ensures that insoluble dirt particles are separated from the pumped-around washing liquid. Cleaning this filter is made considerably easier if it is designed as a basket which can be inserted from the outside into the cleaning device in the manner of a drawer.

Die Vorteile einer Ultraschallreinigung können genützt werden, wenn als Waschvorrichtung ein Waschbehälter mit durch Ultraschall bewegter Waschflüssigkeit vorgesehen und der geschwenkte Waschgutträger zumindest soweit absenkbar ist, bis das Waschgut in den Waschbehälter eintaucht.The advantages of ultrasonic cleaning can be used if a washing container with washing liquid moved by ultrasound is provided as the washing device and the pivoted laundry carrier can be lowered at least until the laundry is immersed in the washing container.

Eine Trockenvorrichtung, insbesondere mittels Luftdüsen, zwischen dem Waschgutträger und der Sprüh- bzw. Waschvorrichtung außerhalb des Schwenkbereiches des Waschgutträgers unterstützt einen möglichst schnellen Reinigungsablauf. Ein besonders rationeller Einsatz mit hoher Auslastung der Waschvorrichtung ergibt sich, wenn diese als mobile Station ausgebildet ist und an wechselnden Orten zur Reinigung des Waschgutes eingesetzt werden kann; dies ermöglicht auch in vorteilhafter Weise möglichst kurze Transportwege und Transportzeiten bei der Reinigung des Waschgutes.A drying device, in particular by means of air nozzles, between the laundry carrier and the spraying or washing device outside the pivoting range of the laundry carrier supports the fastest possible cleaning process. A particularly efficient use with high utilization of the washing device results if it is designed as a mobile station and can be used at different locations for cleaning the laundry; this also advantageously enables transport routes and transport times that are as short as possible when cleaning the items to be washed.

Besonders zweckmäßig ist die vollautomatische Beladung des Waschgerätes und das Waschen sowie Wiedereinschleusen der Werkstückträger in das Fertigungs- bzw. Montagesystem durch Anschluß des Waschgerätes an das übergeordnete Steuerungssystem des Montagesystems gemäß einer Ausgestaltung der Erfindung dadurch, daß das Waschgerät mit der Steuerung der zugeordneten Förderbahn des Fertigungs-bzw. Montagesystems über zumindest eine Steckverbindung in Funktionsabhängigkeit gestellt ist.The fully automatic loading of the washing machine and the washing and reinserting of the workpiece carriers into the manufacturing or assembly system by connecting the washing machine to the higher-level control system of the assembly system according to one embodiment of the invention is particularly expedient in that the washing machine with the control of the associated conveyor track of the manufacturing -respectively. Mounting system is made functionally dependent on at least one connector.
