Description

METHOD FOR CURING PAINTS BY MEANS OF UV RAYS
The following invention relates to all the technological sectors in which flat component parts (for example, furniture parts, shelving parts, etc.) are covered with a layer of paint which is then dried by means of the application of ultraviolet rays emitted by special sources which, in most cases, consist of UV- ray lamps.
In accordance with the present state of the art, the method used to perform this drying operation is carried out as follows: the painted part to be dried is displaced by a conveyor belt or by a similar system with the painted surface directed upwards and, during its displacement, is made to pass through light beams emitted by a first set of UV-ray lamps. The layer of paint, which is for example acrylic or polyester based, undergoes a first drying stage which is not complete, however, since these paints, upon coming into contact with the air and the moisture contained in it, are subject to chemical reactions which tend to delay and prevent drying thereo .
At the same time, in the case of painted parts which have a more or less marked porosity, the air contained in the pores expands, owing to the heat irradiated by the ultraviolet rays, and forms small bubbles which project from the surface of the paint which has been treated as described above, namely which is not yet hard and rigid enough to withstand the expansion of said bubbles, but is hard and rigid enough to prevent the air from escaping to the outside.
It is therefore required to perform necessarily smoothing of the layer of semi-hardened paint by means of a special filler repainting station, and a further drying operation, so that the conveyor belt passes through a first sanding station and a second set of UV- ray lamps which continue the paint drying operation.
Usually, during this second drying stage as well, some small bubbles reoccur and must be definitively removed by causing the painted part to pass through a further sanding station.
Drying of the paint is then completed, while tne part is made to pass through a third and last set of UV-ray lamps.
In order to perform the method described above, it is therefore necessary to have a plant, located downstream of the painting station, comprising among other things a filler station and a sanding station and tnree consecutive sets of UV-ray lamps, resulting, as can be easily imagined, in a high energy consumption. During the process itself, moreover, on account of the prolonged exposure of the paints to the open air, substantial pollution of the environment occurs, tnis being made worse also by the accompanying aoundant production of ozone by the said three sets of UV-ray lamps.
It is also necessary to mention the high overall cost of the plant and the large area occupied D\ it, together witn the direct and indirect effects thereof on the production costs. In order to eliminate all the abovementioned drawbacks, i.e. m order to reduce tne environmental pollution, limit the space occupied by a drying plant and reduce the energy consumption, the inventor of the present invention has devised a method, which is novel as far as he is aware, whereby, during drying, by means of UV rays, of a layer of paint applied onto flat surfaces, a sheet of transparent material is arranged facing and pressed against said layer, thereby remaining in between the layer of paint itself and the source which generates the ultraviolet rays for the whole duration of the drying process.
The present invention m fact consists of a method for performing drying, by means of ultraviolet rays, of a layer of paint as described in the preamble of the accompanying Claim 1, characterized by the characterizing part of the same claim.
The present invention also relates to some preferred types of plant suitable for implementing the said method. The method according to the invention will now be described m more detail, with reference also to the accompanying drawings, m which:
Figure 1 shows the arrangement of the conveyor belt with respect to the layer of paint applied onto a flat surface belonging to a part which is displaced by means of a conveyor belt;
- Figure 2 shows a first example of a plant for implementing tne method m question, m which the strip is unwound from a first reel, πeing wound onto a second reel with a section between the reels which is kept facing and pressed against the layer of paint by two pressure rollers;
- Figure 3 shows another example of embodiment of a plant for implementing the method according to the invention, which is similar to that shown in Figure 2, except for the fact that a single tensionmg roller replaces the said unwinding and winding reels and the transparent sneet is formed as an endless strip. The essential features of the method according to the invention may oe determined from Figure 1: in said Figure it can be seen how, according to th s method, a layer 1 of paint which can be dried by means of exposure to ultraviolet rays has been applied beforehand onto a flat surface 2 of a part 12.
One or more lamps 3m, 3n (two in the Figure) form a set 3 which acts as a source of UV rays; the said layer of paint 1 passes through the light beam emitted by the said lamps 3m, 3n, while the part 12 is displaced by the action of a conveyor system 5 of a known type.
A sheet 4 of transparent material, for example polyester, has a section 4t opposite the lamps 3m, 3n, which is arranged facing and kept pressed with a predefined pressure against the layer 1 of paint, remaining in between the latter and the lamps 3m, 3n for the whole period of time needed to achieve complete drying of the layer 1 of paint.
3y means of this method, the said transparent section 4t firstly prevents the air from coming into contact with the layer 1 of paint, thus preventing the phenomena of delayed drying mentioned above; secondly, by exerting a pressure on the layer of paint, it prevents the formation of the already described small bubbles on the surface layer of the latter, so that it is not required to perform any repainting, filler and/or sanding operation. This results in a saving of up to 70% in the quantity of paint to be applied in order to achieve the same level of quality.
The chemical reaction of hardening of the layer of paint 1 occurs moreover in a "closed state", i.e. without any contact with the air, and this further reduces the environmental pollution. Moreover a single set of UV-ray lamps is used, resulting in a significant reduction in the energy required for the method.
If it is taken into account that, compared to the known methods, two or more filler or sanding stations and at least two further sets of UV-ray lamps are dispensed with, it may be considered that the method according to the invention helps save up to 70-80% of the energy used, with a qualitative result in the finish of the painted surfaces which is far superior to those obtained hitherto.
The persons skilled in the art may be able to design different types of plant suitable for implementing the method according to the present invention; the inventor, however, wishes to suggest two solutions which in his opinion are particularly functional and low-cost.
The first of said solutions is illustrated m Figure 2; the parts 12 are transported by a conveying roller system 5 which moves as indicated by the arrow A and are displaced (arrow B) opposite a set 3 of one or more UV-ray lamps 3m, 3n. The said transparent sheet 4 is unwound, by means of the friction exerted on it by each part 12, from a first reel 6 and is rewound by a second (motor-driven) reel 7, and a section 4t thereof is kept pressed against the layer of paint 1 present on the part 12 by two pressure rollers 8, 9, being located between the said lamps 3m, 3n and the layer of paint (1) itself for the entire duration of the paint drying process, said duration being adjustable by modifying the speed of displacement of the conveyor system 5.
Figure 3 snows a second example of embodiment of a plant which is designed to implement the method and which is similar to that shown m Figure 2 described hitherto, except for the fact that the said two reels 6, 7 are replaced here by a tensiomng roller 10, and the transparent sheet 4 is formed as an endless strip 11 which is wound around the tensiomng roller 10 and the two pressure rollers 8, 9, which are entirely similar to those of the preceding embodiment, said rollers keeping the section 4t of the transparent sheet 4 pressed against the layer of paint 1 during the drying process. The inventor suggests using, m the most frequent type of processing operations, a transparent sheet made of polyester with a thickness which may vary between 15 μm and about 1.5 mm since with this range of thicknesses it is possible to combine, for each application, an adequate transparency with good tensiomng of the section thereof which is pressed onto the layer of paint.
The polyester material, although not being the only one which can be used, also offers good resistance to even the high temperatures produced by UV rays.
Variations in the method and the manner of constructing the plants suitable for implementation thereof may be made by persons skilled in the art, said variations nevertheless falling within the scope of protection of the present application, provided that they refer to that expressed in the accompanying Claim 1 or in the remaining claims.
