Operating method for an atomiser and a corresponding coating apparatus
First Claim
1. An operating method for an atomiser for the coating of components comprising:
- a) Presetting a desired spray jet width for the atomiser;
b) Application of a spray jet of a coating agent through the atomiser, wherein the spray jet comprises an actual spray jet width;
c) Determination of at least one application parameter which reproduces a characteristic of the applied coating agent or an operating variable of the atomiser;
d) Discharge of a first guide air flow onto the spray jet for shaping the spray jet;
e) Controlling the actual spray jet width to the preset and desired spray jet width by adjusting the first guide air flow depending on the determined application parameter, including modifying the actual spray jet width to a modified spray jet width in response to a change in the at least one application parameter during the application of the spray jet.

Abstract
The invention relates to an operating method for an atomiser (1) for the coating of structural components, particularly of vehicle body parts, with the following steps: Application of a spray jet of a coating agent through the atomiser (1); discharge of a first guide air flow (11) for the formation of a spray jet; determination of at least one application parameter (η, γ, T, BC/CC, Qvarnish, n, U,) which reproduces a property (η, γ, T, BC/CC) of the applied coating agent or an operating variable (Qvarnish, n, U) of the atomiser (1) as well as influencing of the first guide air flow (11) as a factor of the application parameter (η, γ, T, BC/CC, Qvarnish, n, U,). Within the framework of the invention, there is the alternative option that fluctuations of the application parameters and, based thereon, variations of the spray jet width are taken into account by means of an adaptation of the path spacing (d) between the adjacent coating agent paths for the purpose of keeping the path overlapping constant. Furthermore, the invention comprises a corresponding coating apparatus.
