摘要:
There is provided an electrodeposition coating apparatus for dipping a body (B) into an electrodeposition coating liquid (L) filled in an electrodeposition tank (1), which includes a first circulation system for causing a flow direction of the coating liquid (L) in a surface area and an intermediate area through which the body (B) passes in the electrodeposition tank (1) to be opposite to a moving direction of the body (B), and a second circulation system for causing a flow direction of the coating liquid (L) in a bottom area in the electrodeposition tank (1) to be equal to the moving direction of the body (B).

Objects, (4) especially vehicle bodies (4), are guided through a painting installation comprising at least one bath (2) in a continuous translation movement, by means of a transport device (5). Immersion devices carry the objects using a carrier structure (61) which is connected to the transport device (5) in such a way that it can be pivoted by a pivoting arm (50, 51). A first drive device (54, 55, 56, 57) causes a pivoting movement of the pivoting arm (50, 51) about a first axis. A second drive device (78, 79, 80, 81) is used to pivot the carrier structure (61) about the second axis, in relation to the pivoting arm (50, 51). One such immersion device enables very different kinematics of the immersing and emerging movement to be carried out.

The invention relates to a plant for the treatment, in particular the cataphoretic dip coating of objects, in particular of vehicle chassis (4), whereby the objects (4) are run by means of a transport car (5) through several treatment stations and on so doing are dipped in at last one treatment container (91) and retrieved therefrom again. The transport car (5) comprises a chassis (7, 8, 9 to 12), which travels along the trajectory of the objects (4), at least one pivot arm (50, 51), connected to the chassis (7, 8, 9 to 12), a mounting (61) joined to the pivot arm (50, 51), for at least one object (4) and independently operated drives (32, 33, 56, 57, 80, 81) for the translational displacement and the pivoting displacement of the at least one pivot arm (50, 51) and the mounting (61). The transport car (5) can be used not only for transport of the objects (4) for treatment but can also have a service basket (90) fixed thereto, suitable for the accommodation of at least one operative. The service basket (90) can be brought into any position which can be reached by the pivot arm (51), by means of the transport car, whereby the alignment of the service basket (90) in maintained permanently in the vertical by means of a special device (92). The operative in the service basket (90) can carry out maintenance and cleaning work on all reachable objects and surfaces in a convenient manner.

The invention relates to a method for introducing and removing workpieces, especially automobile bodies, into or from an appropriate workpiece (1) surface processing area (20, 70) where the workpieces (1) are removably secured to holders (7) each of which having a rotational axis (13, 41, 61) perpendicular to the direction in which the workpieces move. Said rotational axes (13, 41, 61) are engaged in a continuous translation movement at a constant speed and the workpieces (1) are steered simultaneously along one of these rotational axes (13, 41, 61) at the beginning or end of the processing area (20, 70) and continuously guided in the direction of the translation movement, rotating by approximately 180°. The invention also relates to a device for workpiece surface processing and an installation to process automobile body surfaces.

Glass containers (3) are taken to a high temperature in an annealing furnace (7) and removed from the annealing furnace belt (5) by grips (16) of a gripping device (12). The gripping device (12) is then moved by a handling device (13) first vertically upwards, then horizontally above a fluidised bed (18) and then downwards into the fluidised bed in order to coat the glass containers (3) with a powder; it is then taken upwards out of the fluidised bed (18) and finally moved horizontally over a conveyor belt (22). There, the glass containers (3) are released from the gripping device (12) and set down on the conveyor belt (22) which takes the powder-coated glass containers (3) through a second curing region (27) in which the powder coating is cured to form a substantially duroplastic layer.
摘要:
Um ein Verfahren zum Fördern von Fahrzeugkarosserien durch ein Behandlungsbad zur Oberflächenbehandlung der Fahrzeugkarosserien zu schaffen, bei dem die Flüssigkeit des Behandlungsbades den eintauchenden Fahrzeugkarosserien nur einen geringen Eintauchwiderstand entgegensetzt und die Strömungsgeschwindigkeiten der Flüssigkeit des Behandlungsbades relativ zu den eintauchenden und austauchenden Fahrzeugkarosserien niedrig gehalten werden, wird vorgeschlagen, daß die Fahrzeugkarosserien vor dem Einbringen in das Behandlungsbad aus einer Standardstellung, in welcher Fensteröffnungen der jeweiligen Fahrzeugkarosserie oberhalb der Bodengruppe der Fahrzeugkarosserie angeordnet sind, in eine Kopfüberstellung, in welcher die Fensteröffnungen der jeweiligen Fahrzeugkarosserie unterhalb der Bodengruppe der Fahrzeugkarosserie angeordnet sind, überführt werden und daß die Fahrzeugkarosserien anschließend in der Kopfüberstellung in das Behandlungsbad eingebracht, durch das Behandlungsbad gefördert und aus dem Behandlungsbad wieder ausgebracht werden.
摘要:
Glasbehälter (3) werden in einem Kühlofen (7) auf erhöhte Temperatur gebracht und vom Kühlofenband (5) durch Greifeinheiten (16) einer Greifvorrichtung (12) ergriffen. Die Greifvorrichtung (12) wird anschließend durch eine Handhabungsvorrichtung (13) zunächst senkrecht nach oben, dann waagerecht über ein Wirbelsinterbett (18) dann senkrecht nach unten in das Wirbelsinterbett zur Beschichtung der Glasbehälter (3) mit einem Pulver, dann wieder senkrecht aus dem Wirbelsinterbett (18) nach oben hinaus und schließlich in waagerechter Richtung über ein Transportband (22) bewegt. Dort werden die Glasbehälter (3) von der Greifvorrichtung (12) freigegeben und auf dem Transportband 22 abgesetzt. Das Transportband 22 fördert die mit Pulver beschichteten Glasbehälter (3) durch eine zweite Aushärtezone (27), in der die Pulverschicht zu einer im wesentlichen duroplastischen Schicht ausgehärtet wird.

摘要:
A method and apparatus (1) for coating exterior surfaces of heated glass containers (B) exiting from a lehr at a controlled temperature. A coating chamber (5) is provided with a dipping zone (6), a thermal ageing zone (7) and a curing zone (8). Conveying means (9) defines a coating path (2) extending successively through the dipping, thermal ageing and curing zones (6, 7, 8) of the coating chamber (5), and is operable to convey the containers (B) along the coating path (2) so that the containers (B) are arranged in a non-contact relationship with one another. A coating vessel (18) is provided in the dipping zone (7) for containing a bath of ultraviolet light radiation curable liquid coating material (M), the conveying means (9) being arranged to dip containers (B) being conveyed thereby along the coating path (2) so as to apply a coating of the coating material (M) to exterior surfaces of the containers (B). Radiation means (23) is located within the curing zone (8) and operable to subject the coated containers (B) being conveyed along the coating path (2) to irradiation with ultraviolet light radiation for curing the coating. The atmosphere in the coating chamber (5) is controlled so that the atmosphere within at least the curing zone (8) is inert to the coating material (M).
