Problems solved by technology

[0008] On the one hand, due to their unsatisfactory application efficiency and the resulting overspray, known application devices incur extremely high investment costs for the necessary flushing and the need for explosion protection
[0009] On the other hand, due to said overspray occurring during operation, the known application equipment is associated with expensive operating costs due to paint loss and disposal costs of the overspray
In addition, the use of large amounts of paint also means a high load or threat to the environment

Embodiment Construction

[0117] figure 2 The cross-sectional view in FIG. 1 shows a painting installation according to the invention, which partly corresponds to the conventional painting installation shown in FIG. 1 , so to avoid repetition, reference is made to the above description, wherein the same reference numerals are used for corresponding details.

[0118] The specific features of the painting installation according to the invention initially consist of the fact that the painting robots 3, 4 do not use rotary atomizers as application means but use application devices 8, 9, each of which comprises an oscillation generator SE and can be called be the droplet generator or applicator head. Each application device 8, 9 has a higher application efficiency, which is more than 90% higher than that of a rotary atomizer. In this way, less overspray is likely to occur because the application devices 8, 9 are capable of forming coating agent droplets, in particular paint droplets, with substantially the...

Abstract

The invention relates to a coating device and to an associated coating method for coating components with a coating medium, in particular for painting motor vehicle body components and / or motor vehicle accessories with a paint. The coating device comprises at least one applicator unit (8, 9) for expelling the coating medium from at least one coating medium nozzle. Furthermore a drop generator (TE; TE') can be provided in order to impose a vibration and / or an instability on the coating medium in order to generate coating agent drops (70) and / or to break down the coating medium into drops (70). The applicator unit (8, 9) is preferably provided in order to expel at least one coherent coating medium jet (70') which breaks down into drops (70).

Description

technical field [0001] The invention relates to a system for coating parts with a coating agent, more particularly for painting motor vehicle body parts and / or accessories thereof (such as bumpers, mirror housings, bumper covers, etc.) Coating device. Furthermore, the invention also relates to a corresponding coating method. Background technique [0002] FIG. 1 shows a cross-section through a conventional painting installation for painting body parts of motor vehicles. Here, the motor vehicle body parts to be painted are transported at right angles to the plane of the drawing via a painting cabin 2 onto a conveyor belt 1 , wherein said motor vehicle body parts are then handled by painting robots 3 , 4 in a conventional manner. paint. The painting robots 3 , 4 have several rotating robotic arms, each arm carrying an application device such as a rotary atomizer, air atomizer or so-called airless device via a multi-axis robot arm. [0003] A disadvantage of these known appl...
