Definitions

  • the invention relates to a method and apparatus for painting animals and/or objects, using a coating paint product.
  • the invention relates to an apparatus used for coating solid bodies with coating paint liquid compounds, which are vaporized and/or micronized and/or atomized while spraying a body to be coated, in accordance with a novel and particularly convenient and cost effective method.
  • the main drawbacks arising from this practice are based on the fact that the manual massage action is particularly difficult if the expected degree of coating is particularly high, e.g. when a liquid, a cream, a lotion or a general compound having tanning properties is to be applied, in which case the body on which said compounds are applied shall not only exhibit a degree of coating next to 100%, but also and further a particularly even and homogeneous coating, due to the fact that said coating shall allow the skin that is treated with the above compounds to react to sun exposure, or to react according to the chemical properties of the compounds and substances in use.
  • This is the case of sunless tanning creams and lotions, by which certain structural components of the skin react chemically by color variations (like in the case of
  • the skin is composed of various cells having different characteristics, which can give it important characteristics to be considered in the design and optimization of an apparatus for coating it.
  • the skin has a multifaceted surface having both a lipophilic and lipophobic character, which allow the skin to function as a kind of barrier against unwanted impurities, and yet . to let the gaseous component of the atmosphere in and water vapor or liquids out.
  • application apparatus is that; due to the particular texture of the skin, a full and evenly homogeneous coating is hardly attainable. It is also known that, in order to fully and homogeneously coat a body, one more person is often needed, especially for coating regions of the body that are hardly reachable by the subject (e.g. back, shoulders) and skin areas at joints, in whose folds, often due to the massage movement, the liquid and/or cream in use stagnates.
  • Apparatuses and methods are known in the art for spraying electrostatically charged liquid paints, to enhance the adhesion of the coating paint solution or liquid on the skin of the subject, which obviate many of the drawbacks caused by manually coating a body with liquids and/or creams, particularly having tanning properties.
  • closed booths are used, in which coating paint liquids are sprayed on subjects in said booths . From prior art various types of closed booths are known for painting with coating paint products having various useful
  • paint liquid or solution to enhance the adhesion of the coating paint solution or liquid is induced at the spray nozzles .
  • This invention has the object of obviating these drawbacks by a simple, cost-effective and easy to implement arrangement, which is also more interesting for the subject that is expected to use said invention, by providing a painting booth of the open type, which is made of at least two walls disposed one in front of the other and has one or more paint liquid or solution spray nozzles through which said liquid is propelled under pressure/' and exits therefrom in a finely micronized and/or atomized and/or vaporized form, and used various methods to charge electrostatically the solution and/or liquid being used, to achieve the purpose of fully and homogeneously coat the body.
  • said painting booth is conformed in such a manner as to form a sort of shower cabin, which is composed of at least two walls, preferably made of a transparent material and placed one in front of the other in a discontinuous manner, so as to leave at least two areas uncovered by said walls, which are particularly suitable to allow the movements of the incoming and ingoing subjects to be exposed to painting cycles .
  • an arrangement involving the construction of painting booths formed by two opposed walls, as described above is particularly interesting in that it allows to obviate certain typical drawbacks of prior art closed booths, as this particular arrangement allows people who may not feel at ease in
  • booths may be simply used on beaches and other public spaces as they need no particular maintenance, unlike closed booths .
  • a further improvement consists in that said booths need . no' particular for cleaning and ventilate the environment like those in. use for closed booths, because the natural aeration of the environment (booth) limits the stagnation of the coating paint liquid aerosol inside the environment, and the booth wall washing process is further facilitated by the openings on the sides of the walls and by the presence of a rotating platform, provided as an easily removable and cleanable tray, which is highly useful for possibly recycling the coating paint solution in use during the painting cycle or for a faster disposal of the exhausted component of said solution, as there is no pipe connection through which said solution would be forced to flow.
  • the above well-known apparatuses use spray nozzles which induce the electrostatic charge on the coating paint liquid to be used in the painting step, while said liquid exits from the nozzles and, as discussed above, may have the drawback of retaining an electric charge, though minimal, which might be discharged on the user of the apparatus, if he/she moves inside the closed booth.
  • a further advantage provided by the apparatus of this invention consists in that it provides various methods for inducing an electrostatic charge on the coating -paint liquid.
  • a tank is used which can induce the electrostatic charge on the solution contained therein by using one or more spark plugs and/or diodes and/or electrodes which are directly in contact with the liquid or dipped therein, thereby preventing the electrostatic charge from being induced at the spray nozzles, and consequently preventing any passage of electrostatic current from the nozzles to the body of the subject being painted, due to a contact between the subject and the charged nozzle .
  • a further embodiment uses micronizing and/or atomizing and/or vaporizing nozzles inside a polarization further containing electrodes and/or diodes and/or spark plugs, which come in direct contact with the vaporized mist of the liquid used for the painting process and directly induce the electrostatic charge thereon by contact.
  • the liquid is passed through a transparent coil, which is wound around or in contact with at least one UV lamp.
  • UV rays are known to be able to induce an electrostatic charge on a liquid passing near it, without any direct contact with electrostatically charged metal elements, and thereby preventing any short circuit condition.
  • micronizing and/or vaporizing and/or atomizing nozzles are provided in a polarization chamber wherein micronization and/or vaporization and/or atomization occur until liquid droplets of -about 20 ⁇ m are formed, which droplets are naturally charged With a positive electrostatic charge due to the high pressure exerted thereon.
