Embodiment Construction

[0050] Figures 1A-1C The method steps according to the invention of the coating method are shown in the form of a flow chart. In this exemplary embodiment, the coating method is used for painting vehicle body components in a painting installation, wherein the painting is carried out by means of rotary sprayers which are each guided by a multi-axis painting robot. It is further mentioned that the method steps described in detail below are repeated continuously during the painting operation in order to enable a dynamic adaptation of the operating parameters of the rotary atomizer.

[0051] In a first step S1 it is initially ascertained whether the interior of the interior of the vehicle body component or the exterior of the vehicle body component is to be painted externally. This distinction is important because different requirements are placed on the operating parameters of the rotary sprayer (eg diverted air flow, high pressure) when painting the interior on the one hand and...

Abstract

The invention relates to a coating method and a coating system for coating the component surface of a component with a coating agent by means of an atomizer (4) in a coating system, in particular for painting a body part of a motor vehicle with paint, comprising the following steps: moving the atomizer (4) over the component surface of the component to be coated, or moving the component in the spray jet, thereby applying the coating agent to the component surface by means of the atomizer (4). The atomizer (4) is operated with at least one electrical and / or kinematic operating variable (U, Q+, Q-), comprising a certain high voltage (U) for the electrostatic charging of the coating agent and / or a certain rotational speed of a rotating spray element of the atomizer (4). According to the invention, the electrical and / or kinematic operating variable (U, Q+, Q-) of the atomizer (4) is dynamically varied during the movement of the atomizer (4).

Description

technical field [0001] The invention relates to a coating method and a corresponding coating system for coating components with a coating agent, in particular for coating vehicle body components with paint. Background technique [0002] In modern painting installations for painting vehicle body components, a multi-axis painting robot is usually used, which guides a rotary sprayer as a painting device. In this case, the painting robot guides the rotary sprayer over the component surface along a programmed trajectory, wherein the trajectories are typically arranged in a zigzag manner relative to one another. Alternatively, however, it is also possible to pass the components to be coated past the sprayer by means of suitable conveying technology or by robots. Unlike previously used painting machines such as roof and side machines, this type of painting robot is very flexible in its trajectory guidance. Furthermore, the use of a painting robot greatly reduces the number of rot...
