Definitions
- the invention relates to a ⁇ method for metered Applying liquids to material webs according to the preamble of claim 1 and a device to carry out the procedure.
- Spray processes have the disadvantage of one in particular high environmental impact due to the open system.
- WO-A-93/07969 describes a method for metering Applying liquids to material webs described the properties of the applied To improve coating.
- the object of the invention is to overcome the disadvantages of the prior art to eliminate technology and a process and a Device for the dosed application of liquids to develop on material webs with which one homogeneous coating and minimal environmental impact are guaranteed.
- Ultrasonic vibration system (sonotrode) 1 formed, in which a feed 2 for a liquid, here for example for a lacquer.
- a feed 2 for a liquid here for example for a lacquer.
- an air duct 3 for the introduction of Compressed air arranged above the sonotrode 1 .
- the material web to be coated for example here a film web 4, is on the surface of the Sonotrode 1 performed (Fig. 1).
- the sonotrode 1 consists of an ultrasound bar, which for example consist of a large number in parallel working transducer is built, which together excite the vibration beam in phase, but are decoupled from each other against transverse swinging.
- the sonotrode could also be formed from a transverse oscillator.
- the sonotrode 1 swings over the entire working width with exactly the same amplitude A, frequency and Phasing.
- the film web 4 to be coated is by means of Overpressure of the duct 3 applied to the surface the sonotrode 1 is pressed.
- Compressed air can also be an elastically rotating roller or a similar agent can be used to control the Slide 4 with a defined pressure force over the Lead sonotrode 1. It can also be done by the Choice of film tension the necessary pressure can be achieved.
- a gap 5 which is with the set working frequency of the sonotrode 1 periodically opens.
- the gap size corresponds approximately the size of the set amplitude A.
- the gap 5 is evenly applied to the film 4 distributed.
- the sonotrode 1 swings perpendicular to the plane the film web 4.
- the film web 4 is rounded to 6 Sonotrode 1 out and over a tear-off edge 7 by derived there.
- the rounding 6 and the tear-off edge 7 are integrated in the sonotrode 1, both guide means can also run separately become.
- the rounding 6 is ⁇ and the tear-off edge 7 is formed with an outlet angle ⁇ , where the condition applies ⁇ ⁇ .
- the amount of paint is adjusted by a metering pump, not shown, as a function of the throughput speed of the film web 4, so that the amount of paint is determined exactly per m 2 of film web 4.
- Fig. 2 is shown schematically how the Vibration-decoupled paint supply via channel 2 in the sonotrode 1 can take place.
- the compressed air line 3 is designed to be adaptable to the width of the film web 4.
- the paint supply can also be adjusted and lockable edge cover segments (not shown) with a vibration decoupling on the feed pipes take place instead of the paint supply shown through the sonotrode 1.
- the sonotrode 1 For homogeneous coating of a flat surface or it is also a material web with a liquid conceivable, the sonotrode 1 with the feeds for the Liquid and the pressure medium to move.
