Definitions

  • the invention relates to a method for spray painting cylindrical bodies while avoiding paint loss through overspray and paint aerosols.
  • the method can be applied in particular to rotating cylindrical bodies for their exterior and interior painting. It is particularly suitable for the interior painting of cans that are open on one side. It can be done continuously.
  • the conventional spray painting of open cylindrical hollow bodies, in particular cans is described, for example, in US Pat. No. 4,246,300.
  • the inside is sprayed out individually with a spray varnish using the cycle method, can by can.
  • the paint spray jet is drawn 5 - 15% of its width beyond the edge of the rotating can.
  • the object of the invention is to provide a method in which this paint loss during spray painting is prevented and disposal measures and environmental damage are avoided.
  • This object is achieved by the method forming a subject of the invention for spray painting the inner and / or outer surfaces of rotating cylindrical objects, which is characterized in that the result of the painting of an object to be painted the overspray is almost completely absorbed by at least one further object to be painted.
  • the method according to the invention is particularly suitable for spray painting with fan-shaped guidance of the spray jet, which can be done, for example, by using conventional slot nozzles.
  • the method according to the invention can preferably be used continuously for spray painting the inner and / or outer surfaces of a plurality of cylindrical ones
  • Objects are carried out.
  • the overspray formed during the painting of a first article and the aerosols formed from the paint are generally absorbed by a second article to be painted.
  • the method according to the invention can be applied, for example, to the exterior painting of rotating cylindrical hollow bodies, such as cans and, in particular, barrels. At least two objects to be painted are guided next to each other at the smallest possible distance so that the small body gap during the painting of the first item and overspray and paint aerosols are absorbed by a second item.
  • the method according to the invention is also particularly suitable for the interior painting of cylindrical hollow bodies which are open on one side.
  • These are in particular cans, for example conventional food and beverage cans.
  • the cylindrical hollow bodies are therefore generally referred to in the following as cans.
  • the procedure is preferably such that at least two cans during their contact with the (in particular fan-shaped) spray jet with their open ends are inclined so that they overlap without contact.
  • the angle of inclination of two cans to be painted one after the other is 5 to 60 °, based on their axes of rotation.
  • At least two cylindrical hollow bodies e.g. cans to be subjected to an interior painting are brought together so that a loss-free transition is formed at their opening edges for the paint spray jet.
  • the required overspray spray jet from a previous can is applied without loss as a pre-coating in the next can.
  • the height of the hollow bodies In the embodiment in which two cans or cylindrical hollow bodies are inclined relative to one another, it is advantageous to offset the height of the hollow bodies relative to one another, so that if the openings are inclined relative to one another, an overlap of the openings is possible without material contact.
  • paint cans in particular food and usual beverage cans
  • the overlap of the can openings is preferably also 0.5 to 40 mm.
  • the height shift and the overlap are each preferably 0.5 to 10 mm.
  • the process according to the invention not only prevents the loss of paint from overspray, but also reduces the mechanical and electronic complexity of conventional spray painting, for example can spray painting.
  • the cans are staggered in height.
  • the Bl can is higher than the B2 can, which enables contact-free overlap of the can openings when inclined by the angle alpha.
  • Alpha represents the angle of inclination of the cans B1 and B2 against each other; it relates to their axes of rotation C.
  • the cans B1 and B2 are held at their closed ends by rotatable holding devices D1 and D2, for example magnetic brackets, and guided past the spray jet A. Of course, it is also possible to guide the spray jet A past the cans.
  • Fig. 2 shows the overlapping open ends of the cans B1 and B2 seen from the spray jet A. This is shown in a fan shape in FIG. 2. It can be seen that it acts on both bodies to be painted simultaneously, without an overspray loss E.
  • Fig. 3 shows an embodiment in which several cans B, which are held at their closed end by a rotatable holder and are guided over an inner circular path F, so as to enable a continuous flow of material from cans and paint.
  • the cans on the inner circular path are continuously inclined towards one another at an angle beta, which is preferably 10 to 200 °.
  • the spray jet A can be guided continuously over at least two cans so that there is no loss of overspray.

Abstract

Selon un procédé permettant de peindre au pistolet des surfaces internes et/ou externes d'objets cylindriques en rotation (B1, B2), notamment lorsque le jet de pulvérisation (A) est en forme d'éventail, l'excédent de peinture pulvérisée pendant la peinture d'un objet (B1) à peindre se dépose sur l'objet suivant (B2) à peindre. Ce procédé est particulièrement utile pour peindre l'intérieur de boîtes, les boîtes étant inclinées les unes par rapport aux autres, pendant qu'elles sont en contact avec le jet de pulvérisation en éventail, de sorte que leurs extrémités ouvertes se chevauchent sans se toucher.
