Definitions

  • the present invention relates to a method and a device for applying a coating such as paint or varnish on an article.
  • the varnish is sprayed, conventionally, with a spray gun at a painting or varnishing station.
  • the painting or varnishing station is generally located in a location away from the molding station and the item is exposed during transport towards this painting or varnishing station with dirt and if necessary at a risk damage to the decoration made on it.
  • Patent application JP-54-93015 describes a device making it possible to pour a certain amount of a coating into the bottom of a hollow body and make rotate the hollow body to spread the coating on its inner surface.
  • Patent application DE 34 20859 describes a process allowing the surface treatment of small parts.
  • Patent application DE 25 59 144 describes a device capable of being introduced into a conduit to paint the interior surface thereof.
  • the present invention relates to a new method for applying a coating such as a paint or varnish on a hollow article, in particular an article in molded plastic material such as a housing body, a housing cover, a plug or a bottle, the opening of the bottle can be narrower than the bottom.
  • the coating is deposited on the article without having to be dispersed beforehand in the atmosphere in the form of fine droplets.
  • the invention thus makes it possible to reduce the amount of paint or varnish coming in contact with the atmosphere and therefore reduce solvent losses by evaporation.
  • This varnish or this solvent-free paint is advantageously heated, being preferably brought to a temperature higher than room temperature, for example a temperature between 40 ° C and 50 ° C, in order to increase its fluidity.
  • the coating can be applied automatically in a closed enclosure, near the molding station, this enclosure being more compact than traditional equipment.
  • the surface on which the coating is deposited is located inside the article and a sufficient amount of coating for it to rise under the effect of force at least partially centrifugal along the side wall of the article.
  • the coating deposited at the bottom of the interior surface rises under the effect of centrifugal force along the side wall of the article even if it is vertical.
  • the side wall of the article is at least partially cylindrical with the same axis as the axis of rotation about which is driven article.
  • the side wall of the article can be stepped.
  • the invention also makes it possible to paint or varnish articles which do not could not be spray painted or varnished in a conventional manner, either because the opening is too small to allow the introduction of a spray nozzle to inside the article, either because the air present at the bottom of the article constitutes a gas mattress tending to oppose the diffusion of the spray aerosol.
  • the coating which is used does not contain any solvent, it is possible without fear of depositing the excess coating on the surface to be coated since it is easy to recycle without risk to the environment a residual amount of coating which would find it ejected from the article during its rotation.
  • stopping the rotational drive of the latter is preferably carried out immediately, by blocking for example of the drive mechanism, to avoid possible sagging on the outer surface of the item.
  • the surface on which is deposited the coating spreading under the effect of centrifugal force is substantially flat or slightly domed and located outside the article.
  • the coating can be applied by spraying in the form of a spray, by spraying or by other means over the entire outer surface of the article which is not covered by spreading the coating under the effect of centrifugal force.
  • the rotation speed of the latter is zero or very low (for example less than 5 r / s) to avoid the risk of ejection of the coating on first contact with the article.
  • the speed of rotation of the article increases very rapidly during start-up to avoid any run-off linked to the geometry of the surface on which the coating is spread out.
  • the article can reach, for example, a rotation speed of between 50 r / s and 100 rpm in less than a second.
  • Direct application of the coating to the exterior surface of the article may take place by means of a nozzle whose positioning and orientation are adjustable.
  • the means for applying the coating directly on the surface of the article has a nozzle inclined downwards and located slightly above the periphery of said substantially flat surface or slightly domed.
  • it is used to paint or varnish the interior surfaces and / or exterior of the article a coating which can crosslink under the effect of radiation ultraviolet.
  • the coating deposited on the article is crosslinked then that it is still rotating.
  • the invention also relates to a device for applying a coating to a article having at least a substantially flat or slightly curved surface as described in claim 19.
  • the device comprises an enclosure inside which takes place the item rotation.
  • the means for applying the coating directly to the article includes a nozzle whose inclination and positioning relative to the support rotary are adjustable.
  • the device further comprises means for exposing the article to ultraviolet radiation.
  • the distribution member is connected to a reservoir containing a coating without organic solvent.
  • the device includes means for warm the coating.
  • the invention is particularly suitable for applying a coating to a hollow article such as a housing body, a housing cover, a stopper or a bottle.
  • the means for applying the coating directly to the rest of the surface of the article advantageously comprise a nozzle inclined downwards and situated slightly above the periphery of said substantially planar surface or slightly bulged.
  • the coating used is advantageously a paint or varnish without solvents organic.
  • FIG. 1 There is shown in Figure 1 a device 1 for applying to an article 2 a coating such as paint or varnish.
  • Article 2 is here constituted by a cover of a make-up case having a generally rectangular in shape.
  • the top 3 of this cover 2 is substantially planar and horizontal and the sides 4 are substantially vertical and directed downward.
  • the top 3 of the cover 2 could also be convex towards the outside by example.
  • the device 1 comprises on the one hand a dispensing member 5 making it possible to place in the center of the surface constituting the top 3 of the cover 2 a drop of paint or varnish and secondly means for directly applying the paint or the varnish on the sides 4 of the cover 2 and in the corners, these means being constituted by example by a nozzle 6 as shown.
  • the device 1 also comprises means 7 for supporting the cover 2, able to drive the latter in rotation about a vertical axis of rotation X.
  • the cover 2 rotates inside an enclosure, not shown.
  • article 2 is rotated around the X axis by one revolution on itself.
  • the nozzle 6 is inclined slightly obliquely downwards and is situated slightly above of the cover 2 so as to be able to reach the corners of the latter.
  • the coating is emitted by nozzle 6 in the form of a jet and not an aerosol.
  • the latter After depositing the drop of paint or varnish on the cover, the latter is very quickly rotated to reach its rotation speed in less than 0.5 s nominal for example between 50 r / s and 100 r / s.
  • the workpiece is kept rotating at a speed of 50 to 100 r / s for 2 to 5 s in the example described.
  • a solvent-free varnish or paint which can crosslink is used. under the action of ultraviolet radiation.
  • the coating is heated in the example described to 45 ° C so as to be made more fluid.
  • the coating which is ejected from the article can be recovered in the enclosure and recycled after just a filtration operation.
  • the cover 2 is kept in rotation and subjected to ultraviolet radiation 8 causing it to crosslink as illustrated in the figure 5.
  • the coating used is preferably a paint or varnish without organic solvent, this coating being slightly warmed before application, by being brought for example to 45 ° C.
  • the coating can even gain the upper edge 14 of the cover 2, as illustrated in figure 10.
  • Nozzle 6 is not used when the coating is deposited on the surface inside of the article.
  • the article After the coating has been deposited and spread, the article is subjected for example to a ultraviolet radiation which causes its polymerization.
  • any hollow article such as a housing body, a housing cover, a stopper or a bottle, cylindrical or not, of circular section or not, the opening of which has a section for example between 0.25 and 10 cm 2 .
  • FIGS. 11 and 12 show two hollow articles, symmetrical of revolution, having a frustoconical side wall 16 widening towards the top in the case of the example of FIG. 11 and a stepped side wall comprising two truncated cones 17 and 18 in the case of FIG. 12.
