Application method and application system
Applying a coating medium may include: emission of a coating medium jet from an application device and positioning the application device relative to the component with a particular application distance between the application device and the component, so that the coating medium jet impacts on the component and coats the component. The application distance (d) can be smaller than the disintegration distance of the coating medium jet, so that the coating medium jet impacts with its continuous region on the component.
1. A system for application of a coating medium onto a component, comprising:
an application device arranged to emit a coating medium jet in response to a switch, wherein, after emerging from the application device, the coating medium jet has a continuous region in the jet direction until said jet reaches a disintegration distance, whereupon, after the disintegration distance, the coating medium jet then disintegrates into droplets that are separate from one another in the jet direction;
a positioning device to position the application device at an application distance away from the component, the application distance being no greater than 200 mm while the application device is emitting a coating; and
means for sensing that senses the application distance of the application device, the means for sensing coupled to the switch wherein the switch emits the coating medium jet in response to the means for sensing only when the sensing means detects the application distance to be less than the disintegration distance of the coating medium jet.
2. The system of claim 1 , further comprising:
a nozzle plate, included in the application device, in which a plurality of application nozzles are arranged, each of which emits a coating medium jet, wherein the coating medium jets together generate a stripe on the component.
3. The system of claim 2 , wherein the stripe has a width of at least one-hundred micrometers, and the stripe has a width of a maximum of one meter.
4. The system of claim 2 , wherein
the application device emits a plurality of coating medium jets which are oriented substantially parallel to one another;
distances between directly adjacent coating medium jets is large enough such that the adjacent coating medium jets do not merge between the application device and the component;
for emission of the coating medium jets, the application device has a plurality of application nozzles with a specified nozzle internal diameter and a specified nozzle spacing, wherein the nozzle spacing is at least equal to three times the nozzle internal diameter.
