Problems solved by technology

[0003] A disadvantage of these known applicators is that the nozzle geometry is fixed and can only be changed by exchanging the corresponding nozzle
However, nozzle replacement requires a certain length of time, which is problematic in thick-substance systems for the continuous coating of motor vehicle body components (for example adhesive coating) due to the time required because the nozzles Variations can limit the cycle times achievable during painting

Embodiment Construction

[0034] The figures show different views of an applicator 1 for applying a strip of a thick substance (eg adhesive, sealant) to a component 3 (eg a body component of a motor vehicle). ) on the component surface 2.

[0035] The application of strips of thick substance to component surfaces is theoretically known from the prior art, so a detailed description of the application of strips of thick substance can be omitted, for which reference is made to the prior art in this field.

[0036] Furthermore, it should be mentioned that the drawings illustrate only schematically the principles of the invention, whereby variations in size and design of various components are possible.

[0037] The applicator 1 firstly has a hollow cylindrical inner tube 4 through which the coating agent to be applied flows during operation and which has a front opening 5 at its free end.

[0038]Furthermore, the applicator 1 has an outer tube 6 which surrounds the inner tube 4 on the outside and extends ...

Abstract

The invention relates to an applicator (1) for the application of a coating agent (for example a high-viscosity material) to a component (for example a body component of a motor vehicle) comprising anozzle (4-11) having a nozzle opening with a specific nozzle geometry, in particular for applying a bead of high-viscosity material to the surface of a component. The invention provides that the nozzle geometry of the nozzle opening is adjustable without exchanging the nozzle (4-11), in particular by a relative movement of two nozzle parts (4, 6). The invention also comprises an exchangeable part(6, 12) for such an applicator (1) and an operating method therefor.

Description

technical field [0001] The invention relates to an applicator for applying a coating agent, such as a thick substance, in particular an adhesive or a sealant, to a component, such as a body component of a motor vehicle, in particular with For applying strips of thick substance to the surface of a component. Furthermore, the invention relates to a replaceable part for such an applicator and a corresponding operating method therefor. Background technique [0002] It is known from the prior art to apply so-called adhesive strips to component surfaces by means of applicators. The applicator robot guides the applicator over the component surface along a specific path. During this movement, the applicator releases adhesive from the nozzle onto the component surface such that the adhesive then forms an adhesive bead on the component surface. Known nozzles for such applicators generally comprise a tube which narrows in the direction of flow and which has a V-shaped nozzle groove ...
