Definitions

  • the invention relates to a device for electrostatic spray painting of plastic parts in a spray booth using a conductive liquid, which is applied by spraying on the surfaces of the parts before the painting process.
  • the conductive liquid is a solution of polar conductive substances in rapidly volatile alcohols.
  • the leading liquid therefore consists of a solvent and a carrier material, the solvent serving for the solution and uniform distribution of the carrier material during application.
  • the objects to be painted are so-called hangers through a spray booth, they are hung individually before painting on the conveyor hooks of the hangers and must be removed from them after painting.
  • Such a conveyor can not be used for long, rod-shaped profiles, because the rod-shaped components would deform too much only at their ends when hanging, or because they require a suspension in several places along their length in a complex manner.
  • the latter has the disadvantage in particular that additional points of contact would be created which the paint cannot reach, so that repainting would be required at these points.
  • the invention is therefore based on the object to design a device of the type mentioned so that the painting of long, rod-shaped objects, such as profile bars for doors and / or windows made of plastic or metal coated with plastic is possible in a simple manner without time-consuming additional manual operations is.
  • At least one roller conveyor is connected upstream and downstream of the spray booth, at least some of the conveyor rollers being driven and the conveyor rollers, which are preferably made of steel, simultaneously serving for power dissipation and being earthed.
  • the method according to the invention ensures that the ground contact with the conveying rollers is maintained both in front of and behind the spray booth.
  • the application roller expediently consists of a wear-resistant plastic which is deformable to such an extent that the application to the conveyor roller, which is a steel roller in a manner known per se, is ensured.
  • This plastic is advantageously low-pressure polyethylene.
  • Such a roller combination can be arranged both on the input and on the output side of the spray booth, it being possible for a plurality of such roller combinations to be connected in series if necessary.
  • the conveyor roller loaded with the conductive liquid can be driven directly, while the application roller is driven by its circumferential contact with the conveyor roller.
  • the application roller is advantageously rotatably mounted on the trough containing the conductive liquid.
  • the trough can be arranged to be adjustable, preferably pivotable about a horizontal axis.
  • the trough is expediently pivotably mounted between the two parallel rails of the roller conveyor and carrying the conveyor roller and suspended from the latter. This changes the distance between the conveyor roller and the application roller and thus the contact pressure between the two rollers when the tub is pivoted.
  • An actuating device is expediently provided for this purpose. This can consist of at least one set screw which acts on the side of the trough facing away from the conveyor roller beyond the pivot axis. In this way, the respective position of the tub can be adapted to the circumstances and readjustments can be made when worn.
  • a cleaning device which consists of at least one conveying roller loaded with cleaning fluid, to the roller combination arranged on the spray booth exit side for exposure to the conductive liquid in the conveying direction.
  • a medium-volatile glycol ester is particularly suitable as a cleaning liquid.
  • the cleaning device expediently has a trough containing the cleaning liquid, in which a brush roller acting on the associated conveying roller rotates.
  • a brush roller acting on the associated conveying roller rotates.
  • both the brush roller and the associated conveyor roller are preferably driven in opposite directions, so that the conveyor roller is simultaneously brushed off with the application of the cleaning liquid and maintains its full conveying function.
  • the trough containing the cleaning liquid can be arranged pivotably in the same way as the trough containing the guiding liquid.
  • an arrangement can also be provided in which the two-sided bearings of the brush roller are arranged so as to be vertically displaceable on the trough, the trough being arranged in a stationary manner on the rails of the roller conveyor.
  • the bearings of the brush roller can be adjusted by means of set screws that are supported against the tub.
  • cleaning devices can be arranged one behind the other and assigned to the successive conveyor rollers. Three such devices are preferably provided.
  • a wiper is provided in front of the first conveyor roller downstream of the spray booth in the conveying direction.
  • a scraper can have the shape of an elastic scraper plate, for example made of rubber or an elastic plastic, and is in contact with the profile surface to be cleaned. It is also possible to combine such a scraper with the scraper or brush roller of the cleaning device, wherein the scraper acts against the direction of rotation of the brush roller. Wiping off the excess paint from the brush roll presents no difficulty, since it reaches the scraper when it is diluted by the cleaning liquid.
  • an ionization device can additionally be provided directly at the spray booth exit, in the area of which the ambient air is charged with the opposite polarity to the painted profile, so that a charge reduction takes place as a result.
  • the guide liquid is expediently applied to the profiles to be painted in a separate application booth upstream of the spray booth in the conveying direction, the guide liquid being applied on all sides to the continuous profile by means of air spray guns. It is advisable, however, to exclude those sections of the underside of the profiles from the application of the master solution that are not to be coated with lacquer later. In any case, those parts of the surface that are in contact with the conveyor rollers must be provided with conductive solution to ensure adequate earthing.
  • the air spray guns can be spaced apart in the order booth. It is expedient if two air spray guns are arranged above the workpiece to be coated, while a further one acts obliquely on the workpiece from below.
  • air spray guns one of which acts on the workpiece from above and three laterally at an angle from above and below.
  • the air spray guns can be arranged one behind the other in the conveying direction, the air spray gun acting from above on the workpiece lying in the conveying direction in front of the other air spray guns and at least two side air spray guns being arranged one behind the other.
  • the unnecessary conductive liquid is also provided according to the invention to blow off a certain air pressure from the surface of the profile to be coated by means of blowing devices.
  • a preferred embodiment for such blow devices consists in a closed blow ring, which the air spray guns in Direction of conveyance is downstream and has diagonally directed openings spaced against the profile to be painted.
  • This blow ring is particularly advantageous because it ensures that all surface parts of the profile to be coated are evenly acted upon by the air flow.
  • a collecting funnel for the removed dripping or blown off guide liquid is provided below the air spray guns in the application booth, so that the excess guide liquid can be recycled.
  • the spray booth is equipped with two high-speed guns and one air gun for the supply of paint, the air gun advantageously being arranged in the middle between the two high-speed guns.
  • the high-speed pistols With the high-speed pistols, the surface of a rotating bell is applied with the paint at a speed of about 12 to 15000 revolutions per minute and, due to the centrifugal force that occurs, is torn off over the edge of the bell, so that atomizing cones are generated. With the air pistol, an atomizing jet is directed against the workpieces in a manner known per se.
  • jet-generating air pistols is therefore generally required in order to achieve deep grooves or the like to be able to, since the walls of such grooves form a Faraday cage, which prevents spray mist from entering the grooves without pressure energy. This deficiency is remedied with the air gun due to the additional kinetic energy imparted to the jet.
  • the individual guns can be arranged in the spray booth in a height-adjustable manner.
  • the invention further provides that at least one support roller is arranged inside the spray booth.
  • the support roller is expediently made of a plastic, preferably of a paint-repellent plastic, such as polyamide, but preferably polyethylene.
  • the support roller is expediently mounted interchangeably in upwardly open forks on a support frame, so that it can be exchanged with a handle.
  • the transmission also advantageously consisting of a paint-repellent plastic.
  • one or both pins of the support roller can be provided with pinions which automatically engage in corresponding drive pinions of the transmission when inserted into the fork.
  • the arrangement of several such support rollers one behind the other within the spray booth is possible.
  • All of the conveyor rollers expediently have a roughened surface to improve transport on the one hand and to improve application on the other hand, and they can have a slightly concave spherical shape.
  • the surface of the conveyor rollers with a conveyor covering, which consists of a fabric and can absorb the conductive liquid. Accordingly, it must be designed to be absorbent. Since these coverings can become dirty, it is expedient if they are designed in such a way that they can be removed quickly, and according to a preferred embodiment the conveyor cover is designed as a cylindrical sleeve which is formed by means of a
  • Zipper or the like can be fixed under tension on the respective conveyor roller.
  • a fabric is expediently chosen which shrinks under the influence of liquid, such as a fabric used for pressure rollers.
  • a conveying liquid bath must also be assigned to the conveyor rollers provided with such a casing.
  • a spray booth 1 in which the electrostatic painting of plastic profiles or plastic-coated profiles 2 (see FIG. 2) is to be carried out, two high-speed guns 3 and 4 and an air gun 5 for the paint supply are arranged.
