Bei den bekannten Methoden für die Trommeltechnik stellt die Kontaminierung von Luft und/oder Wasser mit Chemikalien ein Problem dar. Zusätzliche Reinigungsanlagen sind bei der Anwendung solcher Techniken notwendig. Trotz hohem gerätetechnischem Aufwand ist die direkte Rückführquote von unverdünnten Behandlungslösungen aus Tauchtrommeln in die Behandlungsbäder innerhalb einer Produktionslinie, wenn überhaupt, gering.In the known methods for drum technology, the contamination of air and / or water with chemicals is a problem. Additional cleaning systems are necessary when using such techniques. Despite the high expenditure on equipment, the direct return rate of undiluted treatment solutions from submersible drums into the treatment baths within a production line is low, if at all.
Verdünnungs-Methoden lösen nicht die Umweltschutz-Probleme, sondern verlagern sie nur von der Produktionslinie in den Bereich der Abwasseraufbereitung.Dilution methods do not solve the environmental problems, but only move them from the production line to the area of wastewater treatment.
Hier schafft die Erfindung Abhilfe.
Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, lößt die Aufgabe, durch ein Sperr- und Dränagesystem, ohne Verwendung von Luft und/oder Wasser, nach dem Ausheben der Tauchtrommel aus einem Behandlungsbad die Behandlungslösung direkt in das Behandlungsbad zurückzuführen. Die Rotation der Tauchtrommel, die Drehrichtung, die Positionierung der Sperr- und Dränagevorrichtung im Stop- und Go-Betrieb, sowie die Transportabfolge werden von einem Steuersystem gesteuert, wobei die Programmabfolgen frei wählbar sind.Ein Positionselement an der Tauchtrommel ermöglicht es in Verbindung mit dem Steuersystem, die Stop-Position der Sperr- und Dränagevorrichtung bereits im Behandlungsbad und/oder während dem Ausheben der Tauchtrommel aus einem Behandlungsbad, zu fixieren.The invention provides a remedy here.
The invention, as characterized in the claims, solves the problem of returning the treatment solution directly to the treatment bath by means of a blocking and drainage system without using air and / or water after the immersion drum has been lifted out of a treatment bath. The rotation of the submersible drum, the direction of rotation, the positioning of the locking and drainage device in stop and go mode, as well as the transport sequence are controlled by a control system, whereby the program sequences are freely selectable Control system to fix the stop position of the blocking and drainage device already in the treatment bath and / or while the diving drum is being lifted out of a treatment bath.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß Chemikalien eingespart werden, die Spülwassermenge reduziert und der Energieverbrauch gesenkt wird, teure Abwasseraufbereitungsanlagen vermieden werden und die Spülwasserkreislaufführung für eine abfallarme/abfallose Galvanik ermöglicht wird. Erreicht werden diese Vorteile dadurch, daß Behandlungslösungen, zur Abfallvermeidung, bereits innerhalb der Produktionslinie in die jeweiligen Behandlungsbäder zurückgeführt werden. Weitere Vorteile sind die einfache Ausrüstung von Tauchtrommeln mit einer Sperr- und Dränagevorrichtung, sowie die Möglichkeit der einfachen Nachrüstung vorhandener Anlagen und die Zeitensparung beim Trocknungsprozeß der Ware in Trockenöfen.The advantages achieved by the invention are essentially to be seen in the fact that chemicals are saved, the amount of flushing water is reduced and the energy consumption is reduced, expensive wastewater treatment plants are avoided and the flushing water circuit is made possible for low-waste / waste-free electroplating. These advantages are achieved in that treatment solutions for avoiding waste are returned to the respective treatment baths within the production line. Further advantages are the simple equipping of submersible drums with a locking and drainage device, the possibility of simply retrofitting existing systems and saving time during the drying process of the goods in drying ovens.

Fig.11 zeigt eine Anlage im Querschnitt; zur galvanischen und/oder chemischen Behandlung von Massenteilen in Tauchtrommeln, die durch Transporteinheiten (Hub- und Transportwagen) durch die Prozeßstationen transportiert werden.11 shows a plant in cross section; for the galvanic and / or chemical treatment of mass parts in submersible drums which are transported through the process stations by transport units (lifting and transport vehicles).
In den Abbildungen, Fig.1 bis Fig.11, sind die für den Wirkmechanismus der Sperr- und Dränagevorrichtung relevanten Einzelteile; und die mit dem Funktionsablauf verbundenen Transportabfolgen dargestellt. Sperrleiste (2), Dränageleiste (3) und der Trommelmantel (4) bilden den geraden Dränagekanal (DK) oder den gebogenen Dränagekanal (DK'). Bevor eine Tauchtrommel (1) aus einem Behandlungsbad (13) ausgehoben wird ist es vorteilhaft, den Dränagekanal (DK) an einer bestimmten Stelle des Kreisumfang mittels Positionselement (9), im zusammenwirken mit dem Steuersystem, zu positionieren.In the figures, Fig.1 to Fig.11, the individual parts relevant to the mechanism of action of the locking and drainage device; and the transport sequences associated with the functional sequence are shown. Blocking strip (2), drainage strip (3) and the drum casing (4) form the straight drainage channel (DK) or the curved drainage channel (DK '). Before an immersion drum (1) is lifted out of a treatment bath (13), it is advantageous to position the drainage channel (DK) at a certain point on the circumference by means of a positioning element (9) in cooperation with the control system.
Wird nach dem Ausheben der Tauchtrommel (1) aus einem Behandlungsbad (13) die Tauchtrommel (1) mittels Trommel-Drehantrieb (16) in Richtung (B) gedreht, kann die Ware und die Behandlungslösung nicht mehr am Innenmantel der Tauchtrommel (1) abgleiten, Ware und Behandlungslösung werden durch die Sperrleiste (2) und die Dränageleiste (3) mitgenommen; über die Dränageleiste (3) wird die Behandlungslösung zwangsweise aus der Tauchtrommel (1) abgeschieden. Eine Abtropfleiste (15) sorgt dafür, daß die austretende Behandlungslösung auch vom Außenmantel der Tauchtrommel (1) getrennt wird.If, after lifting the immersion drum (1) out of a treatment bath (13), the immersion drum (1) is rotated in direction (B) by means of a rotary drum drive (16), the goods and the treatment solution can no longer slide off the inner jacket of the immersion drum (1) , Goods and treatment solution are taken through the locking bar (2) and the drainage bar (3); The treatment solution is forcibly separated from the immersion drum (1) via the drainage strip (3). A drip tray (15) ensures that the emerging treatment solution is also separated from the outer jacket of the immersion drum (1).
Die Drehbewegung der Tauchtrommel (1) kann kontinuierlich, oder um ein überlaufen der Behandlungslösung über die Sperrund Dränagevorrichtung zu verhindern, schrittweise erfolgen. Der Lochdurchmesser (5) der Perforation des Trommelmantels (4) reicht meistens nicht aus, um die Behandlungslösung schnell und mit hohem Wirkungsgrad aus der Tauchtrommel (1) abzuscheiden. Erfindungsgemäß ist deshalb der Teil des Trommelmantels (4), der zum Dränagekanal (DK) gehört, mit großen Öffnungen (6) versehen. Weiter kann noch durch Öffnungen (7) an den zwei Stirnseiten (8) und (8') der Tauchtrommel (1) das Abflußverhalten der Behandlungslösung aus dem Dränagekanal (DK) verbessert werden.The rotary movement of the immersion drum (1) can take place continuously or in order to prevent the treatment solution from overflowing via the blocking and drainage device. The hole diameter (5) of the perforation of the drum jacket (4) is usually not sufficient to separate the treatment solution quickly and with high efficiency from the immersion drum (1). According to the invention, the part of the drum jacket (4) that belongs to the drainage channel (DK) is provided with large openings (6). Furthermore, the outflow behavior of the treatment solution from the drainage channel (DK) can be improved through openings (7) on the two end faces (8) and (8 ') of the immersion drum (1).
Im Verlauf der Drehbewegung fällt das Warenkonglomerat, das sich in der Tauchtrommel (1) befindet, auseinander und in den Innenraum der Tauchtrommel (1) zurück. Die Massenware erschüttert dabei den Trommelmantel (4) stoßartig; als Folge wird noch Behandlungslösung aus der Perforation (5) des Trommelmantels (4) abgestoßen. Zur Umrüstung vorhandener Anlagen können ganz einfach die Trommeldeckel (4') mit einem Dränagekanal (DK) ausgerüstet, oder gegen einen solchen mit Dränagekanal (DK) ausgetauscht werden.In the course of the rotary movement, the goods conglomerate, which is located in the immersion drum (1), falls apart and falls back into the interior of the immersion drum (1). The mass-produced goods shake the drum jacket (4) abruptly; as a result, treatment solution is still expelled from the perforation (5) of the drum casing (4). To convert existing systems, the drum cover (4 ') can easily be equipped with a drainage channel (DK), or can be exchanged for one with a drainage channel (DK).
Für die Verfahrensabfolgen werden die Tauchtrommeln (1) von der Station (14) mittels Transportsystem (10), an das eine nach zwei Seiten ausfahrbare Auffangwanne (11) angebracht werden kann, durch die Behandlungsbäder (13) transportiert. Während dem Transport der Tauchtrommel (1) von einem Behandlungsbad (13) zum nächsten Behandlungsbad (13), kann die aus der Tauchtrommel (1) noch abtropfende Behandlungslösung noch in der Auffangwanne (11) aufgefangen werden. Je nach Transportrichtung der Tauchtrommel (11), von Behandlungsbad (13P) nach Behandlungsbad (13S) oder von Behandlungsbad (13P) nach Behandlungsbad (13S), wird zur Rückführung der aufgefangenen Behandlungslösung in das Behandlungsbad (13P) die Auffangwanne (11) nach der einen oder anderen Seite aus dem Transportsystem (10) ausgefahren. Die in der Auffangwanne (11) gesammelte Behandlungslösung wird über das steuerbare Magnetventil (12) in das Behandlungsbad (13P) abgelassen.For the process sequences, the immersion drums (1) are transported through the treatment baths (13) by the station (14) by means of a transport system (10) to which a collecting trough (11) which can be extended on two sides can be attached. During the transport of the immersion drum (1) from one treatment bath (13) to the next treatment bath (13), the treatment solution still dripping from the immersion drum (1) can still be collected in the collecting trough (11). Depending on the direction of transport of the immersion drum (11), from treatment bath (13P) to treatment bath (13S) or from treatment bath (13P) to treatment bath (13S), the collecting trough (11) is returned to the treatment bath (13P) one or the other side extended from the transport system (10). The treatment solution collected in the drip pan (11) is drained into the treatment bath (13P) via the controllable solenoid valve (12).
