Description

A coating device with coating nozzle arrangements for a plastic profile strand is described. The coating nozzle arrangements have, for coating a plastic profile strand, a plurality of first coating nozzles, which are arranged distributed in a coating chamber in a first coating station over the circumference of the plastic profile strand. A plurality of second coating nozzles are arranged in the coating chamber in at least one second coating station along a transport direction of the plastic profile strand downstream of the first coating station.

From the publication US 6,849,310 B2 For example, there is known a continuous surface film for a plastic profile strand which is provided as a weatherproof seal, wherein the surface film is formed by a colloidal powder coating. The surface film may be disposed on a support, a gasket or on a compensating portion of the weatherproof gasket. In this case, the surface film may be colored and selected to provide desired surface properties such as a reduced coefficient of friction.

In particular, sealing profiles made of elastomeric material for a variety of applications can be inexpensively and absolutely stable and formed with low coefficient of friction and made when the profiles made of a non-paint repellent material and after leaving an extruder with a perpendicular to the surface of the profile in the cross-flow direction to a Transport direction of the profile applied Gleitlack be coated. This results in a toothing of the profile surface with the bonded coating, so that correspondingly long service life for the sealing profile can be achieved. It is with a from the publication DE 197 06 804 A1 known methods achieved a continuous free from air bubbles, uniform coating.

The existing rubber, elastomeric plastics or mixtures corresponding profiles are required for a variety of areas and used for all-round seals of moving windows against a profile frame. The profiles are extruded to and annealed in a tempering device, in order to be further treated and to be provided with a further processing favoring coating. Also, this coating can serve in particular in motor vehicle to protect particularly stressed surfaces of the seal from rapid wear.

For this purpose, a conventional coating apparatus which is to apply such bonded coatings has at least one coating nozzle which is to be aligned relative to the transport direction in the crossflow direction perpendicular to the transport direction of the plastic profile strand. However, the reproducibility of the manual alignment of such coating nozzles is limited, so that it comes at least in the start-up phase of coating a plastic profile strand to Einlaufschwierigkeiten and by a non-optimally adjusted coating nozzle can occur during coating a relatively high rejects when starting the continuous coating process.

Moreover, with conventional coating devices, it is not possible to take into account different coating loading requirements depending on the areas of use of individual seal length portions of a wrap-around gasket for doors or windows of a motor vehicle when coating the extruded plastic profile strand.

An object of the invention is to provide a coating device with which reproducibly different load requirements for the coating can be taken into account as a function of the areas of use of individual seal length sections of a plastic profile strand.

This object is achieved with the subject matter of the independent claim 1. Advantageous further developments emerge with the features of the dependent claims.

One embodiment of the invention relates to a coating device with coating nozzle arrangements for a plastic profile strand. The coating nozzle arrangements have, for coating a plastic profile strand, a plurality of first coating nozzles, which are arranged distributed in a coating chamber in a first coating station over the circumference of the plastic profile strand. A plurality of second coating nozzles are arranged in the coating chamber in at least one second coating station along a transport direction of the plastic profile strand downstream of the first coating station. The first coating nozzles are connected to a first paint supply unit and the second coating nozzles are connected to a second paint supply unit which is independent of the first paint supply unit.

Such a coating device has the advantage that on the one hand the layer thickness of a bonded coating of a plastic profile strand over the circumference of the profile of Plastic profile strand can be made different by the at least one first coating station, so that areas of the contour of the plastic profile strand, which are heavily loaded, can be provided with a higher coating thickness than areas that are not subject to sliding load, in which a lubricious coating may even be undesirable, such as For example, in contour areas that are inserted positively into corresponding folds to hold the seal in position.

In these contour regions, it would even be beneficial if no coating that supports the sliding of the seal is applied, but a lacquer layer with completely different properties, such as improved adhesion in the fold of a door frame or window frame. Such a requirement for improved adhesion of a part of the contour contradicts the requirement for a bonded coating in the contour regions in which the sealing profile strand is intended to seal movable parts.

Furthermore, such a coating device has the advantage that sections of the extruded plastic profile strand paint layers can be arranged with different paint types, so that areas where a structure-borne sound transmission as occurs in hybrid and electric vehicles can be attenuated by a special type of paint more than in Areas subject to increased wear.

The more variations in coating thickness, coating color, coating quality, coating properties of different application areas of the paint layers on the plastic profile strand are applied to achieve optimum sealing, for example, vehicle windows or vehicle doors, the more paint stations are in the coating chamber with correspondingly differently aligned nozzle arrangements and the more paint supply units for Different types of paint with different requirement profiles can be provided in the new coating device.

In one embodiment of the invention, the first paint supply unit has a first paint container and the second paint supply unit has a second paint container, wherein an agitator is arranged in each of the paint containers. Such an agitator is intended to maintain the thorough mixing of the coating of volatile components and macromolecules, for example a bonded coating substance or an adhesion coating substance, homogeneously distributed in the paint container. This is particularly advantageous for paint types that apply color pigments during painting, or for paint types that have filler particles such as nanoparticles of graphite or steatite. Such nanoparticles can additionally improve the sliding properties, while particles such as ceramic particles, which have a greater hardness than nanoparticles of graphite or steatite, can be used as paint fillers to improve the wear resistance.

Furthermore, it is provided that a number of paint supply lines to the coating nozzle arrangements are arranged in each of the paint containers. Through the paint supply lines, individual paint types of a paint container are passed to several coating nozzles of a coating station. For this purpose, first lacquer feed lines can project from the first lacquer container, the number of which corresponds to a number of the first coating nozzles, and second lacquer feed lines protrude from the second lacquer container, the number of which corresponds to a number of the second coating nozzles.

These paint feed lines can be grouped together, with each group of one type of paint feeding the coating nozzles of one of the coating stations. For this purpose, peristaltic pumps are arranged in the paint supply lines, the peristaltic pumps of the first paint supply lines having a first common drive and the peristaltic pumps of the second paint supply lines having a second common drive. This has the advantage that the supply lines of each individual group and thus the associated peristaltic pumps provide a uniform and consistent flow rate and a uniform and consistent delivery pressure to the coating nozzles of a coating station.

In this case, the first paint supply unit may have a first type of paint and the second paint supply unit may have a second paint type, which are connected to two different coating stations.

In this case, the first type of paint other color pigments than the second type of paint. This has the advantage that visible areas of a sealing profile have a different color of work than the non-visible areas. Furthermore, it has the advantage that different assembly instructions can be marked by different colors on the length of the plastic profile strand. Furthermore, it is provided that the first type of paint has a different molecular composition than the second type of paint in order to adapt the paint properties to the requirements of different sealing length sections. It is particularly advantageous to use the coating device when the second type of paint identifies filler particles, so that the plastic profile strand can be coated with differently filled types of paint over its length.

With such a coating device plastic profile strands can be created, which are provided for sealing windows or doors or windows of a motor vehicle, the plastic profile strand has on its sealing length different paint qualities. It is also possible that the second length section achieves a higher wear resistance with the second type of lacquer than the first length section with the first type of lacquer, which has higher sliding properties.

In addition, a plastic profile strand produced with such a coating device can have different coating thicknesses and different color pigments on its outer contour of its sealing profile. In addition, the plastic profile strand may have a wear layer adapted Gleitlackschichtdicke in relation to limited Dichtungslängenabschnitte and with respect to limited outer contour regions of the vehicle sealing profile.

In a further embodiment, it is provided that a plastic profile strand for a vehicle door frame gasket of the front vehicle doors has a higher Gleitlackschichtdicke in entry sill area and in a lower B-pillar area than in the A-pillar area and in a roof spar area, especially the lubricating coating in the entry sill area and in the B-pillar area is more stressed by the opening and closing of the vehicle doors.

Furthermore, it is envisaged that the vehicle door frame gasket in the A pillar area and in the roof pillar area of the front vehicle doors has another paint type with higher body sound insulation than a paint type in the entry sill area and in the lower B pillar area. A higher structure-borne sound insulation can be achieved for example by a higher flexibility of the paint coating and a greatly reduced adhesion of the paint coating.
