[0002] Installation for the process of decorative shading of extruded aluminum profiles
[0003]
[0004] Technical Field of the Invention
[0005]
[0006] The present invention corresponds to the technical field of the treatment plants for the production of anodized aluminum profiles, where said anodizing process presents, prior to the anodizing process itself, a series of pretreatment processes of said profiles among which Find the process of decorative shading.
[0007]
[0008] Background of the Invention
[0009]
[0010] Anodizing is an electrolytic process by which a protective alumina layer is formed on the aluminum profile. This process is preceded by a series of preparation stages or pre-treatment processes, which involves an acid or alkaline degreasing stage to remove cutting oils or polishing pastes, and then a shading stage whose function is to remove the layer of Natural oxide of aluminum and give a decorative finish.
[0011]
[0012] The standard design of an anodizing plant is constituted by a large number of vats and phases or processes by means of which the aluminum material must be pre-treated before proceeding to the anodizing itself, being able to later be colored and finally all the material must end a pore sealing process.
[0013]
[0014] A conventional plant can consist of at least the following processes, in which the high number of phases is observed, mainly rinses since the immersion of the profiles in numerous vats is used:
[0015]
[0016]
[0017]
[0018]
[0019] At present, the pre-treatment processes, prior to the anodizing process, as well as the anodizing itself are carried out industrially by immersion of the profiles, normally arranged horizontally, in large volume vats, because the Aluminum profiles are between 6 and 8 meters long.
[0020]
[0021] In total, these facilities consist of a minimum of 14 vats, and their number may be much higher depending on the finishings on the lines. The vats are of great volume, which implies facilities of high costs and dimensions.
[0022]
[0023] Among the processes listed above, the tinting process stands out. This process can be carried out in an acid medium, by means of fluorine salts, or in an alkaline medium by means of caustic soda and aims to eliminate the lines and veins inherent in the extrusion process and reduce the natural brightness of the extruded aluminum, resulting in a finish characteristic decorative. The matte decorative finish, also called natural or matt silver, accounts for approximately 30-50% of the production of anodized aluminum for the building.
[0024]
[0025] Due to the great influence of the tinting process on the final appearance of the material, it is essential that the process is carried out extremely uniformly over the entire surface of the profile, since otherwise a great variety of visual defects in the profiles originate anodized
[0026]
[0027] In addition, as indicated, a large number of vats are required in the current facilities that imply the need for ample space for them, with the cost that entails, so it would be convenient to find a way to achieve a large uniformity in the finishing of the profiles and at the same time reduce the dimensions and the cost of these anodizing facilities if we carry out all the stages before and after the anodizing process, in a single tank or treatment position, by applying the corresponding solution or product in each phase, by spraying.
[0028]
[0029] As an example of the prior art, reference documents WO2011 / 092160 (ES2457267) and WO2015 / 136353 can be mentioned.
[0030]
[0031] In the reference document WO2011 / 092160 (ES2457267) a procedure is defined in which the steps prior to anodizing are carried out by spraying on the profiles in vertical position. However, this process does not include the stage of obtaining a decorative shade, because the anodizing process is used as an anchoring system for a layer of powder paint, not as a final decorative anodizing finish.
[0032]
[0033] In the reference document WO2015 / 136353 a procedure is determined in which both the previous steps and the anodizing itself are performed by spraying the profiles placed vertically or horizontally. However, it is not mentioned at any time obtaining uniform decorative matte finishes on the entire surface of the profiles.
[0034]
[0035] Previous studies have been carried out on an industrial scale, in which the use of different types of spikes has been applied, with different oscillations, flows and rotational movements proposed by this invention to the teachings of what is described in the inventions WO2011 / 092160 and WO2015 / 136353 related to anodizing, the results of which show that in those cases, they do not allow obtaining a matte decorative finish, characteristic of the anodized aluminum sector destined for building.
[0036]
[0037] It is complex that this objective can be achieved by spraying, so that in the background, no systems or processes to achieve uniform matte decorative finishes are found on the entire surface of the aluminum profiles using spray techniques, since in the attack to the metal to achieve these finishes, irregular attack zones and lack of uniformity appear.
[0038]

[0104]
[0105] Detailed description of a preferred embodiment of the invention
[0106]
[0107] In view of the figures provided, it can be seen that in a preferred embodiment of the invention, the installation for the anodizing process with a decorative matte finish of extruded aluminum profiles (1) proposed herein refers to a process of anodizing that presents some pretreatment processes of said profiles (1) prior to the anodizing process, one of said pretreatment processes being a decorative matte finishing process, and comprising at least one pretreatment zone (2) having a plurality of spikes (3) and, an anodizing zone (4) arranged close to the pretreatment zone (2).
[0108]
[0109] Said installation comprises a mobile support structure (5) of the profiles (1), which as shown in Figures 2 and 3.1, is formed by a longitudinal central axis (6) that crosses a first and a second disc (7.1, 7.2) vertical planes, arranged at opposite ends of the central axis (6) respectively, concentrically with it, which have fixing means for each of the ends of each profile, so that the profiles (1) are arranged between both first and second discs (7.1, 7.2), horizontally and parallel to each other.
[0110]
[0111] Said mobile support structure (5) of the profiles (1) has a first position, arranged inside the pretreatment zone (2) and a second position arranged in the anodizing zone (4). In this preferred embodiment of the invention, as shown in Figures 4.1 and 4.2, the installation comprises a single pretreatment zone (2) for the execution of all pretreatment processes including the decorative matte finish.
[0112] Likewise, the installation comprises a drive motor (8) connected to the central axis (6), which generates a rotating movement between 90 ° and 360 ° in opposite directions alternated both in the central axis (6) and in the assembly of profiles (1) fixed to the first and second discs (7.1, 7.2).
[0113]
[0114] The installation further comprises connecting means of at least one metal part of the mobile support structure (5) of the profiles (1) with the positive pole (9) of means for generating electricity, in the second position of the mobile support structure (5), arranged in the anodizing zone (4), where said metal part is connected to the profiles (1), so as to allow the passage of electrical energy to them.
[0115]
[0116] As shown in Figure 2, in this preferred embodiment of the invention, the first disk (7.1) is metallic and the at least one metallic part of the installation connected to the connection means and to the profiles (1) is formed by a third disk (10) fixed to the longitudinal axis concentrically with the first disk (7.1) and with said central axis (6) and so that it is in contact with the first disk (7.1), which in turn is connected with profiles (1).
[0117]
[0118] In this preferred embodiment of the invention, as can be seen in Figures 4.1 and 4.2, the pretreatment zone (2) and the anodizing zone (4) comprise at two opposite ends of the same parallel upper edges (11). suitable for the support of the mobile support structure (5), where in the anodizing zone (4) the positive pole (9) is arranged on one of said edges (11).
[0119]
[0120] Also, in this preferred embodiment of the invention, the mobile support structure (5) comprises a frame shown in Figures 2 and 3.1, formed by a horizontal horizontal support (12) having a first and a second ends (13.1, 13.2) of support on the upper edges (11) of either the pretreatment zone (2) or the anodizing zone (4).
[0121]
[0122] It can also be seen that the central axis (6) of the mobile support structure (5) of the profiles (1) is arranged below said horizontal support (12) and is attached thereto by both ends of the central axis (6) .
[0123] In this preferred embodiment of the invention, it has already been indicated that the metal part of the mobile support structure (5) of the profiles (1) is formed by a third disk (10) in contact with the first disk (7.1 ).
[0124]
[0125] Thus, the connection means of said third disk (10) with the positive pole (9), are formed by a metal plate (14) and by connections (15) between said metal contact plate (14) and the third disk (10) of the installation, connected to the profiles (1). The metal plate (14), as shown in Figures 2 and 3.1, is arranged at the first support end (13.1) of the horizontal support (12), and is suitable for contacting the positive pole (9) when the Mobile support structure (5) is in the second position in the anodizing zone (4).
[0126]
[0127] Said metal plate (14) is suitable for contacting the positive pole (9) when the mobile support structure (5) is in the second position in the anodizing zone (4), shown in Figure 6.
[0128]
[0129] In this preferred embodiment of the invention, the means for fixing the ends of each profile to the first and second disc (7.1, 7.2) respectively, are formed by a series of socket notches and holes (16), arranged in said first and second discs (7.1, 7.2), close to their contour and facing each other.
[0130]
[0131] Said notches of lace and holes (16) of the discs can be different and of different sizes, so that the first and second disc (7.1, 7.2) that interest, according to the notches they present, are used to fit profiles (1 ) determined.
[0132]
[0133] Likewise, as shown in Figures 2 and 3.2, in this preferred embodiment of the invention, the mobile support structure (5) comprises an additional disk (17) for securing the profiles (1), attached to the axis central (6) in an intermediate position between the first and second discs (7.1, 7.2) and parallel to them.
[0134]
[0135] Said additional disk (17) has through holes (18) of the profiles (1), as shown in said Figure 2, each of said through holes (18) being arranged aligned with a pair of notches or holes (16) facing the first and second discs (7.1, 7.2).
[0136] In this preferred embodiment of the invention, both the second disk (7.2) and the additional disk (17) are made of plastic material. In addition, all the discs comprise means for fastening to the central axis (6) suitable to allow their replacement and movement along said central axis (6), by other discs.
[0137]
[0138] Thus, by being able to replace the discs with others, and it is the third disc (10) that is connected to the positive pole (9) of the electric power generation means, the first disc (7.1) used can be replaced by another first disc (7.2) while the necessary pickling of the same is being carried out, whereby the process can be continued without waiting for the initial first pickling (7.1) to be finished.
[0139]
[0140] Likewise, thanks to the fact that the disks are also movable, it is possible to vary the distance between them on the central axis (6), so that it is possible to fix the ends of profiles (1) of any given length.
[0141]
[0142] In this preferred embodiment of the invention, the means for fastening to the central axis (6) of each disk are formed by a plate (19) fixed to said central axis (6) and bolted elements (20), where each disk It is formed by two adjacent semicircular sections on the corresponding central axis area (6).
[0143]
[0144] In this preferred embodiment of the invention, as shown in Figure 2, the drive motor (8) of the installation is connected to the central shaft (6) by means of a timing belt (21).
[0145]
[0146] As shown in Figures 4.1 and 4.2, in this preferred embodiment of the invention, the plurality of spikes (3) are arranged on both sides of the mobile support structure (5) in the pretreatment zone (2), located longitudinally and at two levels.
[0147]
[0148] With these spikes (3) the solution corresponding to each process is sprayed on the profiles (1) and since said profiles (1) at the same time are performing a reciprocating rotating movement in either direction of rotation, it is possible to achieve that dissolution reaches all parts of the profile, whatever the shape of the section thereof, thus obtaining a perfect finish in each of the processes.
[0149] Therefore, in a first position of the mobile support structure (5) of the profiles (1), shown in Figure 5, it is located inside the pretreatment zone (2), with the plurality of spikes (3) arranged on both sides of the mobile support structure (5), obtaining a correct finish of the profiles (1) in each process.
[0150]
[0151] In this preferred embodiment of the invention, as already indicated, the installation comprises a single pretreatment zone (2). In this case it is a pretreatment tank, in which all the pretreatment processes are carried out, and for this, in this case the installation also comprises a series of tanks (not shown in the Figures) suitable for storing different solutions, externally arranged to the pretreatment tank.
[0152]
[0153] These solutions, each corresponding to one of the pretreatment processes, at the time that corresponds according to the process being carried out, are sent under pressure by a series of pumps through pipes, to the spikes (3 ) of the pretreatment tank, which spray the corresponding solution on the aluminum profiles (1).
[0154]
[0155] Once the pretreatment processes are completed, the mobile support structure (5) of the profiles (1) moves horizontally from said first position to a second position where it is inside the anodizing zone ( 4), in order to carry out the anodizing process.
[0156]
[0157] In this preferred embodiment of the invention, the anodizing zone (4) is formed by an anodizing vessel and the anodizing process is carried out by immersion. Likewise, the mobile support structure (5) next to the profiles (1), in said second position, are arranged inside said anodizing tank, as can be seen in Figure 6.
[0158]
[0159] In this second position, the metal plate (14) disposed at the first support end (13.1) of the horizontal support (12) of the frame when resting on the upper edge (11) of the anodizing zone (4), in which the positive pole (9) is found, contact is established between them, so that the profiles (1) are connected with electric power means and the process of anodizing them is started.
[0160] To reach this solution, several tests were carried out based on the existing installations in the state of the art and how to proceed in them. The tests were carried out on an aluminum profile of complex section, such as that which can be seen in Figures 7.1 to 7.4, since profiles with sections with wings and complicated shapes, such as that represented in said Figures, are profiles in which it is more complicated to obtain a uniform decorative matte finish over its entire surface.
[0161]
[0162] Thus, in the first place, the first trial detailed below was carried out:
[0163]
[0164] In said first test, it is based on an anodizing treatment plant for profiles, such as those existing in the state of the art, which includes a series of tanks containing each of the chemical solutions used in the process.
[0165]
[0166] To apply the pretreatment solutions to the anodizing by spraying, the tank has been provided with adjustable sprinklers or spreaders (3) on both sides of it with the aim of optimizing the treatment of those areas with difficult access and at different heights. The fixed frame (22) shown in Figure 1, used in the state of the art, supported by the aluminum downpipes (23) is supported in the central position, so that the profiles (1) are attached to said downspouts (23).
[0167]
[0168] The profiles (1) were oriented in the four different ways represented in Figures 7.1 to 7.4 and the brightness and finish were studied in the different AF areas, of the profile, in each of the orientations, according to the direction of action of the spiers on them, represented by arrows in these figures. The resulting aspect was classified from 1 to 3 according to the following criteria:
[0169]
[0170] 1. Bad decorative finish, lack of uniformity and very marked extrusion line.
[0171] 2. Bad decorative finish, lack of uniformity.
[0172] 3. Good decorative finish.
[0173]
[0174] Once the profiles (1) are anodized and sealed, the result observed is that the profiles do not have a satisfactory decorative appearance, due to a non-uniform nuance process, deficiencies appear in the profiles of Figures 7.1 to 7.4 tested according to it is observed in the attached table and, especially in all those profiles (1) that have wings.
[0175] The second test was carried out following the pretreatment scheme described above and the orientation of the spout nozzles (3) was modified, increasing the number of them and also increasing the liquid outlet pressure. The results, as can be seen in the attached table, were not satisfactory in any of the profile orientations.
[0176]
[0177] In the third test, the pretreatment scheme of the previous tests is considered again and then rotary systems are introduced, which cause the spray spouts (3) to rotate 360 ° during the process. Again, the results obtained were not satisfactory in any of the profile orientations.
[0178]
[0179] In the fourth test, and again following the scheme described above, the spraying process was carried out, using a first and second rotating discs (7.1, 7.2), so that the profiles (1) can be positioned on them , which rotate driven by a motor (8), between 45 ° and 180 ° and, the profiles (1) rotate with them.
[0180]
[0181] The first disk (7.1) is connected to the positive pole (9) of the rectifier, by means of a flexible copper wiring as a transmitter of the current from the rectifier to the first disk (7.1) that transmits the load to the profiles (1). The profiles (1) are also tightened by means of standard mooring systems, such as tweezers, clamps or aluminum wire hooks.
[0182]
[0183] This first disc (7.1) acts as an anode and in turn rotates between 45-180 ° so that all the faces of the profiles (1) are subjected to the sprinkling of the tank, interchangeably, since their orientation with respect to the sprinklers It changes during the pre-treatment process.
[0184]
[0185] With this half-turn system in both directions, there are no faces of preferred profiles regarding the projection of liquids, liquid retention or drained liquids.
[0186]
[0187] Thus, in this fourth trial, it was possible to obtain a satisfactory decorative finish on all sides of the profiles, regardless of the orientation in which they were placed and regardless of the profile morphology.
[0188]
[0189] Finally, in the fifth trial, the pretreatment described above was applied by spraying, but in this case the profiles (1) are supported on a first and second rotating discs (7.1, 7.2) and there is also a third outer disc (10) with respect to the position of the first disc (7.1), to which the rectifier is connected, directly fixed on the first disc (7.1) where the profiles are positioned (one). In this way, the third disk (10), which is the main input element of the current to the rectifier, is always fixed, and it is only necessary to strip or exchange the first disk (7.1), from which different interchangeable models can be maintained with different types of grooves for positioning the profiles (1).
[0190]
[0191] With this rotary spray pretreatment system and through the device that allows changing the orientation of the faces of the same, the result is that all profiles of complicated configuration, achieve a uniform decorative finish and low gloss finish, Finish finally sought as a final decorative finish.
[0192]
[0193] This system, a combination of spray pretreatment, combined with a special positioning design, by means of support in two-way turning discs up to 180 ° C, has allowed us to change the positioning orientation of the different faces of the different profiles of carpentry aluminum, allowing at the same time to keep connected to the rectifier, a third disk (10) connected to the anode where the connections (15) are fixed from the rectifier, and on which an interchangeable first disk (7.1) is anchored, which can adapt to different sizes and with different types of grooves, for perfect positioning and rapid change of the same, adapting them to the most appropriate configuration to the material to be treated.
[0194]
[0195] The combination of sprinkler system, together with the adaptation design of an orientation system consisting of a first rotating disk or a first and third superimposed rotating discs, has allowed us to overcome the problem that currently existed of achieving profiles of matt decorative anodized aluminum by a sprinkler or projection system.
[0196]
[0197] This same assembly of the rotating disc (s) that serves as a frame for the pretreatment process, subsequently allows us to rotate the profiles during the immersion anodizing process, avoid screening or preferential areas of current input to the bars and improve heat dissipation produced during the anodizing process.
[0198] Below is the table of test results, in which the results of 1 and 2, unfavorable, have been underlined.
[0199]

[0202]
[0203] For measurements, a glossometer has been used so that the 60 ° indicated is the angle of incidence.
[0204] The brightness ranges are low / matte <10 GU, so both test 4 (rotating disk) and test 5 (double disk) give results with satisfactory and fairly uniform decorative finishes, being useful for later use in the phase of anodizing by immersion.
[0205]
[0206] It is observed that in tests 1, 2 and 3, there is always some face with a poor finish result, either because there is no homogeneous decorative appearance or because the brightness obtained is high, since the brightness with a suitable or admissible decorative finish for The construction sector ranges from 5 to 10 GU.
[0207]
[0208] The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are only to be understood as a basis for the claims and as a representative basis that provides an understandable description as well as sufficient information to the person skilled in the art to apply the present invention.
[0209]
[0210] With the installation for the process of decorative shading of extruded aluminum profiles proposed here, significant improvements are achieved with respect to the state of the art.
[0211]
[0212] Thus, thanks to the combination of sprinkler system together with the design of adapting a mobile structure supporting the profiles with a rotating disk, or as in the case of this preferred embodiment, with two superimposed rotating discs, we It allows to solve the problem that currently exists of getting matt decorative anodized aluminum by means of a spray or projection system.
[0213]
[0214] In addition, the mobile support structure of the profiles itself serves as a frame for the pretreatment process and, subsequently, allows us to rotate the profiles during the immersion anodizing process, thus avoiding shielding or preferential areas of current input to the bars and improving heat dissipation produced during the anodizing process.
[0215]
[0216] Therefore, in general terms, the set consisting of two disks, one more external connected to the positive pole of the rectifier and another internal on which the profiles are supported, means that the external disk does not require maintenance and that only the disk more internal is the one that has to be sanded or chemically treated to remove the Anodic layer formed during the subsequent anodizing process, being able to use different interchangeable external disks according to the different profile models.
[0217]
[0218] In this way, this installation achieves perfect results in the anodizing process with a uniform decorative matte finish on the entire surface of extruded aluminum profiles, also achieving a lower consumption of chemicals and water, so it is very effective .
