    [0003] DIGITAL PRINTING MACHINE TO CARRY OUT SUCH PROCEDURE
    [0005] OBJECT OF THE INVENTION
    [0007] The invention, as expressed in the wording of the present specification, refers to a procedure for the formation of hybrid license plates and to a digital printing machine to carry out said procedure, contributing, to the function for which it is intended, advantages and characteristics, which are described in detail below, which represent an improvement of the current state of the art.
    [0009] More specifically, the object of the invention focuses on a procedure for the formation of registration plates, that is, identification plates of those that are incorporated in transport vehicles and that have common identification symbols and unique characters, which, being of those formed from a metallic or synthetic material support base with the surface of its visible face provided with a sheet of reflective material and a cover of transparent film to protect the aforementioned symbols and identifying characters incorporated between said reflective sheet and said protective film, is distinguished by contemplating a printing phase of the reflective sheet in a digital printer that at the same time automatically incorporates the protective film on it, facilitating its subsequent application on the support base, for which a printing machine has been devised. printing provided with means to carry out said phase of the automatic incorporation procedure of the protective film, which also forms part of the object of the present invention.
    [0011] FIELD OF APPLICATION OF THE INVENTION
    [0013] The field of application of the present invention is framed within the sector of the industry dedicated to the manufacture and formation of license plates, focusing particularly on the field of hybrid plates, that is, made up of a metal support base and printed sheets. digitally with identifying signs.
    [0014] BACKGROUND OF THE INVENTION
    [0016] As is known, one of the manufacturing and forming methods for license plates that are currently being used, replacing plates formed by embossing characters, are those that combine a rigid base with digitally printed sheets that are glued on the plate. The visible surface of the base, for which the use of plate laminating machines is contemplated, which generally have rollers between which said base and said sheets are pressed to fix the adhesive provided between them and join them correctly.
    [0018] The problem is that, when there is more than one sheet to join on the base, which is the most common, since at least one sheet of reflective material is usually provided, which is mandatory in most countries to include in the plate, and an upper protection sheet that prevents said reflective and that the characters or symbols deteriorate with friction, the lamination of the set makes the work of forming the plates more complex and laborious, especially considering that they are usually the Vehicle workshops or distributors who, once the title has been sold and obtained, prepare the corresponding plate with the identifying number that will be unique and different for each vehicle.
    [0020] Specifically, the known procedure usually involves the following steps:
    [0022] - first, print the sheets on a digital printer, generally, on the one hand, the reflective sheet with the symbols that are common to many plates and, on the other hand, the transparent sheet with the particular characters of the plate in question, and
    [0024] - second, joining, in the laminating machine, the two printed sheets with the support base, which can either be done in two phases, that is, by first joining the reflective sheet to the base in a first laminating operation and , later, joining the transparent sheet with the characters on the base with the reflective already glued, or in the same operation but with a specific laminating machine that allows the three elements to be correctly centered at the same time to make them move through the rollers without problems, which makes the process more expensive and requires more skill.
    [0026] Well, the objective of the present invention is to provide a method and a printing machine that allows the automatic joining of the reflective sheet and the sheet transparent in the phase of the digital printer itself to form this type of license plates in a faster, more practical and simple way, avoiding, at least, some of the steps that occur in the conventional procedure so that it can be carried out by any operator without the need for special knowledge or skill and with any conventional laminating machine.
    [0028] EXPLANATION OF THE INVENTION
    [0030] The procedure for the formation of hybrid license plates and the digital printing machine to carry it out that the invention proposes allow to satisfactorily achieve the aforementioned objectives, the characterizing details that distinguish them being conveniently collected in the final claims that accompany the present description.
    [0032] More specifically, the object of the invention focuses, on the one hand, on a process for the formation of license plates, in particular and specifically for the formation of license plates that have common identification symbols and unique characters and are formed from of at least the following overlapping layers:
    [0034] - a rigid lower layer, made up of a metallic support base, preferably made of aluminum, or of synthetic material;
    [0036] - an intermediate layer, consisting of a thin flexible sheet of reflective material with the printed identification symbols and characters, which is glued on the surface of the upper or visible face of the support base, which may or may not be smaller than this , so that the base protrudes perimeter; Y
    [0038] - an upper layer, incorporated on the intermediate layer, and with the same dimension as this, consisting of a transparent and flexible film that acts as a protective cover for the upper surface of the intermediate layer, to which it is attached glued by adhesive.
    [0040] Where said procedure, in substitution of the known phases that contemplate, at least, the use of two different machines to print and join the flexible layers together, such as:
    [0041] - a preliminary phase of printing the identification symbols and characters on the intermediate layer that constitutes the reflective sheet, by using a digital printing machine,
    [0043] - and a subsequent phase of incorporation of the upper layer of protective transparent film on said reflective intermediate layer, at the same time as the rigid base, by means of the use of a laminating machine,
    [0045] It is distinguished by combining both phases into one, by using the same machine to carry out the printing phase of the identifying symbols and characters on the reflective intermediate layer, and incorporating the upper layer of transparent film on said reflective intermediate layer.
    [0047] Thus, the method, according to the invention, is distinguished by comprising a printing phase of the reflective sheet in a digital printing machine that, at the same time, automatically incorporates the protective film on said sheet once printed, facilitating its subsequent phase of Subsequent application of both layers already joined, the reflective intermediate and the transparent upper one, on the base of a metallic or synthetic support with a mining machine.
    [0049] For its part, the digital printing machine that allows to carry out this phase of the procedure is distinguished by comprising, at the exit of the printing unit thereof, where the reflective sheet is ejected once printed, means of automatic application of the protective film.
    [0051] More specifically, said means contemplate, at least, a pair of laminating rollers that, located under a support for the inclusion of a roll of pre-cut film, are linked to an automatic drive mechanism associated with a detector that, in turn connected to the electronics of the printer activates said drive mechanism when it detects the output of the printed reflective sheet so that the rollers move and laminate a pre-cut portion of transparent film from the roll together with said printed reflective sheet.
    [0053] It should be noted that, as already mentioned, the union between said reflective sheet and the transparent film is carried out by means of an adhesive which, preferably, is impregnated on the lower surface of the pre-cut portion of transparent film, for which, prior to its entry between the rollers, it is released from the protective paper that it incorporates by means of means provided for this purpose in the machine.
    [0055] This, however, does not imply a limitation, since, alternatively, it may be the reflective sheet that incorporates, on its upper surface, the adhesive that joins it to the transparent film.
    [0057] DESCRIPTION OF THE DRAWINGS
    [0059] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, the present specification is accompanied, as an integral part thereof, by a set of drawings in which for illustrative purposes and non-limiting, the following has been represented:
