    System and method of coating grooves in carpentry pieces. The present invention relates to a system for coating grooves in carpentry pieces comprising lower rollers (7) and higher rollers (6) with conveyor coils (5a) and collectors (5b) of vinyl film (9) and a removable layer (10), respectively, and a heat pump (11) that helps the adhesion of the coating layers on the grooves (4). The method of coating grooves in carpentry pieces is carried out starting from a flat piece that will be coated, subsequently grooved and finally the lining of the grooves will be carried out by means of the coating system described above.

    Field of the Invention The present invention pertains to the technical field of the manufacture of carpentry pieces coated in series. The invention relates in particular to a system and method of coating grooves in flat woodwork pieces.
    Background of the invention
    Various methods of automated manufacturing of wood surfaces or derivatives are known from the prior art. EP1790464B2 describes a press for coating multiple sides of boards with sheet-shaped material, particularly for coating furniture components or doors or windows made of wood with a sheet of synthetic material, which comprises a surface of upper and lower pressure facing each other and a board support tray provided with a bottom. However, it is not contemplated that
    20 boards have slots or holes, limited exclusively to flat boards.
    It is currently known by technicians the automated manufacturing of the membrane press, in whose process on a board the grooving is carried out in a straight line on the surface. Subsequently the impregnation of adhesive is carried out and
    Coating said surface with vinyl papers or mines, the vinyl adhering to the grooves previously made. However, a sufficiently optimal result is not obtained with this system because the coating may not cover the groove in its entire depth and even open causing a breakage effect.
    30 Another method used when it is desired to achieve boards that include different colors, consists of impregnating adhesive on a flat surface, subsequently placing the vinyl paper or melamine, and making the grooving in a straight line. To achieve the desired color on the board, a layer of solvent paint is applied with a brush, which is a very laborious process and, like the
    In the previous system, the desired finish is not finished.
    It was therefore desirable a system and method of coating grooves in flat carpentry pieces, which would provide a more optimal result in the adhesion of the coating layers in the grooves, previously made in the pieces, avoiding the inconveniences existing in the previous methods of the state of the art.
    Description of the invention
    The present invention solves the problems existing in the state of the art by means of a system and method of coating grooves in flat woodwork pieces, which provides better adhesion of the coating layers in the grooves.
    The pieces to be grooved can be of different materials such as wood, fiber of various densities, agglomerates, PVC or aluminum, thanks to the versatility of the coating system.
    The slotting system in flat carpentry pieces comprises upper rollers with coils transporting coating layers (in this case vinyl film), lower rollers with collector coils of a removable layer (which protects the film adhesive) and heat pumps arranged between said rollers on a flat support.
    The conveyor coils contain the vinyl film that will be supplied to the grooves and which will be adhered by the heat produced by the heat pumps. In turn, as the film is transported, a removable layer will be removed, which will be collected in the collecting coils. All the elements of the system will move horizontally with respect to the grooves of the piece. All this means that the process can be carried out continuously, presenting advantages at the time of series production.
    In addition, the lower rollers contain guide rollers that are the same width as the vinyl film for proper placement of the film in the groove.
    The method of coating grooves in flat carpentry pieces is carried out on the basis of a piece that will be coated, then it will be grooved and finally the coating of the grooves will be carried out by means of the coating system described above.
    In this way, materials and colors can be used for coating the grooves different from those of the piece, and in addition a product with an optimal finish is obtained in a short time thanks to the fact that the coating system works continuously.
    BRIEF DESCRIPTION OF THE DRAWINGS Next, to facilitate the understanding of the invention, by way of illustration, but not limitation, an embodiment of the invention will be described that refers to a series of figures. Figures 1 a and 1 b are a perspective view of the different layers of the piece of
    15 carpentry initially coated. Figure 2 is a perspective view of the grooved piece. Figure 3 is a perspective view of the slot liner system. Figure 4 is a side view of the slot liner system. Figure 5 is a perspective view of the piece with the vinyl film arranged in the
    20 slots
    Detailed description of the invention
    The object of the present invention is a system and method of coating grooves 25 in flat woodwork pieces that provides better adhesion of the coating layers in the grooves.
    As can be seen in Figures 1a and 1b, the cladding method initially starts with a piece (1) of woodwork, several fibers
    Density, agglomerate, PVC or aluminum, which is the basis of the product, to which a coating layer (3), vinyl papers or melamine is adhered, by impregnating it with an adhesive layer (2).
    Subsequently, and once the piece (1) is completely covered, the grooving is carried out in a straight line by using a pantograph consisting of three wide-based drive wheels and a milling cutter with the groove pattern . This instrument makes the grooves always be made with the exact same depth and thus avoiding irregularities that the surface could have. Finally, a piece (1) with the desired grooves (4) is obtained (Figure 2).
    Then, through a system, as shown in Figures 3 and 4, the vinyl film (9) is adhered to the grooves (4). This system is composed of:
    - upper rollers (6) containing conveyor coils (5a) of vinyl film 10 (9) and collecting coils (5b) of a removable layer (9) that protects the film adhesive.
    - lower rollers (7) having guide rollers (8), which will have the same width of said film, in order to align said film with the groove (4) for proper coupling.
    15-heat pump (11), arranged on a flat support (12) between the rollers, which allows the film to adhere to the grooves (4).
    The upper (6), lower (7) and heat pumps (11) rollers move horizontally along the entire part (1), so that the rollers go
    20 supplying vinyl film (9) and removing the removable layer (10) And the heat pump (11) is supplying heat so that the film adheres to the groove (4).
    Once finished, the piece is obtained, as can be seen in Figure 5, in which the grooves are covered with vinyl film (9).
    Once the invention is clearly described, it is noted that the embodiments
    individuals described above are subject to detail modifications
    provided that they do not alter the fundamental principle and the essence of the invention.
