Definitions

• the invention relates to a system for the surface finishing of workpieces according to the preamble of claims 1 and 2, and is intended in particular for the coating of vehicle bodies or body parts.
• the object of the invention is above all to create a system for surface finishing of workpieces, in particular for vehicle bodies, in which different types of coating, e.g. Wet lacquer and powder lacquer coating, in batches one after the other or in succession on a workpiece, can be carried out without having to change the system and, at the same time, the technical-economic outlay can be optimized.
• different types of coating e.g. Wet lacquer and powder lacquer coating
• the object is achieved by a system for surface finishing of workpieces according to claim 1 or 2, which are essentially characterized by the respective characteristic features.
• the system designed according to the invention for the surface finishing of workpieces provides the following advantages, in particular for those for coating car bodies and the like.
• FIGS. 2 to 4 in longitudinal or cross-section the structure of a powder-Z wet lacquer cabin according to the invention.
• FIG. 1 shows an advantageous design of a system A for the surface finishing of workpieces W, in particular vehicle bodies, in which a preparation area B and an area of the surface finishing E are preferably arranged next to one another in the longitudinal direction construction of the latter E essential to the invention, successively in the longitudinal direction, into an application zone G, a section with a plurality of cross conveyors Q1, Q2 and Q3, a drying zone H, a section with at least one cross conveyor Q4, Q5, in which preferably another Buffer zone P lies, a testing and completion
• supply facilities such as Media supply, material storage etc. receiving areas C and D provided.
• the preparation area B, the area of the surface finishing E, and also the installation A itself are enclosed by known, building-like wall structures 1, 2 and 3, respectively.
• the drying zone H containing at least one dryer H1 or H2 or H3 is preceded by at least two application devices G1 ... G3b that at least one after the dryer H1, H2 or H3 or after the following test and completion zone J beginning and fed by at least one cross conveyor Q4 or Q6 located there, second or third conveyor path F2 or F3 laterally past the dryer H1, H2 or H3 is led to at least one of the application devices Gl, ... or G3b.
• a further version of the basic concept of the same rank and equivalent, alternative and generic to the generic term of the preceding solution, is characterized in such a way that at least one of the application devices G1,... G3b provided in the application zone G has a combined powder-Z wet paint booth GK is, which each have a first separator 11 for wet paint and a second separator 12 for powder paint, both separators 11 and 12 are held and displaceably guided 13 in the lower part 6, and that these separators 11 and 12 for optional, alternating docking with the Air-permeable bottom 7 of the powder-Z wet paint booth GK and the exhaust device 10 are formed, see FIGS. 2 to 4.
• Sealing is preferably carried out with a pneumatically controllable hose, ring or sealing lips.
• the second basic variant now provides for the separating devices 11 and 12 to be displaceably guided 13 in the longitudinal direction of the cabin and preferably coupled to one another, and for the air-permeable bottom 7 of the powder-Z wet lacquer cabin GK to be in one
• the longitudinal direction of the cabin and preferably in the middle area has the approximately U-shaped or V-shaped channel 8, which is sealed off from the separating devices 11 and 12 and lowered with respect to the level of the floor 7, the conveying path F1, F2a or F3a runs.
• the channel 8 is preferably irrigated.
• the separating devices 11 and 12 can be displaceably guided 13 in the transverse direction of the cabin, and the separating devices 11 and 12 can be provided several times, preferably as a 3 or 4 combination.
• the system according to FIG. 1 is further and particularly characterized by the combination of the following features:
• the application zone G has a first application device G 1, which is passed through a first conveying path F 1 coming from the preparation area B and which is arranged by means of a downstream one
• Cross conveyor Ql has connection to a dryer Hl
• the dryers Hl to H3 are of multi-lane design, these dryers Hl to H3 preferably each comprising an evaporation and drying section, a stoving section and a cooling section.
• the system according to FIG. 1 now also provides that between the cross conveyor Q4 arranged downstream of the dryers H1, H2, H3 and the testing and completion zone J, the latter faces J and faces that J connected, a buffer zone P and a further cross conveyor Q5 are arranged.
• the head part 4 includes the supply air devices in a known manner, the middle part 5 here with means for applying wet - and powder coating is provided, the lower part 6 is designed in accordance with the above embodiments with various insertable separating devices 11 and 12, and the combined powder-Z wet coating booth GK is known in each case by means of a frame-like substructure 9 on a floor N. is set up.
• This new system according to the invention is characterized in particular by its versatility, low structural and technical outlay and little changeover effort for changing the coating material and the type of coating.
• the application device G1 for the application of a base coating and the application devices G2 ... G3b for the application of a filler, base or first and possibly second topcoat or a final clearcoat are provided and designed as cabins.
• Application device Gl or in one or more of the following application devices G2 ... G3b a coating in the plunge pool, flood system or the like. to perform, or even an electrophoresis bath or the like to be used for priming or decorative surface finishing with possibly subsequent single or multi-layer top and Z or clear lacquer sealing.
