    Description: This invention relates to a coating booth for resin-based powder coating systems for elements of considerable length to be coated that outweighs the other two dimensions, such as aluminum alloy bars and extrusions, or ferrous material structural profiles suspended in a vertical position from an overhead conveyor.
    As is known, powder coating booths in the current state of the art constitute a special station in continuous coating systems in which an overhead conveying system, to which the elements to be coated are hooked, conveys them through the various stations of the system, at which successively the following is carried out [0003] Hook fastening of the elements to be coated on the conveyor, the elements generally assuming a vertical position; Pretreatment of the surfaces of the elements to be coated including degreasing by acid and deoxidation and washing; Drying the elements to be coated; The actual coating process in coating booths by spraying by means of special electrostatic spray guns for spraying resin-based coating powder, which adhere due to the electrostatic effect on the surfaces of the elements to be coated; Final polymerization of the synthetic resins by controlled heat distribution, usually by hot air in an oven through which the elements to be coated are passed; Cooling and dissolving the coated elements of the conveyor and their removal.
    Currently, coating booths are usually in the form of a parallelepiped tunnel closed at the sides, bottom and roof. The overhead conveying system passes through the two open surfaces at the tunnel entrance and exit, normally moves in a straight line, and the elements to be coated are hooked thereto, generally in a vertical position, at a distance apart substantially at the speed the conveyor system, the nature of the elements, their geometry, the type, quality and properties of the coating powders and the system's yield targets.
    As is known, the elements to be coated can be hung by systems with rigid or rotatable hooks on the conveyor, wherein the rotatable hooks also allow the relative rotation of the element to be coated to the conveyor, which allows all the surfaces of the coating powder jet or the series or be exposed to successive rows of electrostatic spray guns. It is also known that the attachment of the elements to be coated with systems that allow their relative rotation, can also cause the wavering of the elements so attached.
    With sudden acceleration or stopping of the transport movement of the conveyor system, this fluctuation can lead to contact between adjacent elements to be coated and cause errors or damage to the surfaces and affect the success of the result of the coating process.
    At the present state of the art, not all of the sprayed coating powders deposit on the elements to be coated in the coating booths and adhere electrostatically thereto.
    The proportion of powders that do not settle floats in the air of the cabin, resulting in
    Danger of excessive concentration and risk of explosion. In order to comply with regulations, as well as for reasons of hygiene and safety at the workplace, the air in the cabin is continuously extracted during operation and air circulation is ensured with air from the outside environment.
    Normally, the air is extracted from the cabin by means of forced ventilation systems by means of suction inlets located on the sides and on the roof.
    The unused coating powders that have been sprayed, but have not been deposited electrostatically on the elements to be coated, are then separated from the extracted air.
    These powders are recovered in a cyclone separator and reintroduced into the coating cycle.
    The coating booths of the prior art have several important disadvantages, u. a. the inferior coating quality of the elements to be coated, which relates to differences in the thickness of the coating powder layer, surface defects such as "orange peel" and problems with penetration of the powder into the tread grooves on elements having complex cross sections.
    In addition, the cabins of the prior art prove to be poorly efficient in the deposition of the coating powder, d. H. the proportion of sprayed powder that electrostatically deposits on the profile before the powder is removed by the cabin air extraction system, resulting in high cost of the coating powders in view of the inadequate efficiency and high cost of the material in the system operating costs ,
    In addition, the prior art booths require complex procedures for changing the coating powder color from one color to another in a continuous-duty coating system, with the risk of contamination between different color powder coating materials and difficulties with respect to coating on the automatic cleaning of the cabin, wherein the operator must enter the spray area of the cabin to perform the cleaning process manually when a color change occurs.
    No less important is that the cabs that are currently on the market offer a low level of safety, ergonomics, hygiene and cleanliness of the cab operator's workplace, and meeting the regulatory requirements for the large-scale system In particular, as regards air extraction from the coating booth, which must be suitable for the substantial amount of powder sprayed and not deposited on the elements to be coated in order to maintain the coating powder concentration in the air within the safety limits (ie below the lower explosion limit) , together with the high energy consumption, in particular as regards the energy required for the air extraction system.
    The most important technical object of this invention is therefore to eliminate the above-mentioned disadvantages of the prior art.
    In the context of this technical object, it is an object of the invention to provide the market with a coating booth for elements of considerable length to be coated, which enables a marked efficiency in the deposition of the coating powders, with regard to the proportion of sprayed powder, which is electrostatically deposited on the profile before the powder is removed by the cabin air extraction system. Another object of this invention is to provide a coating booth that allows the penetration of the powder into the grooves of the profile on elements having complex cross-sections and the change from one color to another in a continuous-duty coating system without contamination risk between different-colored coating powders.
    Another object of this invention is to provide a coating booth that can be automatically cleaned under conditions of absolute safety, ergonomics, hygiene and cleanliness.
    No less important is an additional object of the invention, namely to provide a coating booth which offers limited energy consumption, in particular with respect to the energy required for the air extraction system. These and other objects are achieved by a coating booth according to claim 1 as described below.
    Further features of the invention are contained in the dependent claims.
    The coating booth for continuous operation virtual coating systems, which is the subject of this invention, is illustrated by an approximate, non-limiting example of a preferred but not exclusive embodiment of the invention in the accompanying drawings. 1 shows an exploded view of the cabin without the rows of electrostatic spray guns according to the invention, FIG. 2 shows a schematic top view of the cabin shown in FIG
    Crossbeam of the roof.
    With reference to said figures, a coating booth is shown, which is designated in its entirety by the reference numeral 1.
    In particular, the cabin has an innovative triangular outline, which is schematically identified by a first vertex A, a second vertex B and a third vertex C, in which the conveyor 2 follows an angular path.
    The conveyor 2 enters the coating booth from the side BC, having the peaks B and C as endpoints, and completes a path that guides the elements 3 to be coated to the vertex A and then returns them and causes them to be coated elements 3 from the side BC in a substantially symmetrical position to the apex at the entrance to the cabin exit.
    The elements 3 to be coated, including elements of considerable length, are fastened to the horizontal conveyor conveyor 2 by means of hooks and hang in a vertical position by means of hook systems which do not allow rotation and which limit their wobbling (the hook systems are not in the Plates indicated). Along the approach path of Appendix 2 to the vertex A, a first series of electrostatic spray guns 4 for the coating powders are suitably mounted on the two sides of the elements 3 to be coated, with nozzles 4a pointing in the direction of movement of the conveyor 2, along the Off the plant 2, which leads away from the vertex A, a second series of electrostatic spray guns 5 for the coating powder is suitably mounted on the two sides of the elements 3 to be coated, with nozzles 5a facing in the direction of that of the conveyor 2 is opposite.
    The series of electrostatic spray guns 4 and 5 have a pendulum and controlled movement along a vertical axis, so that the coating powders are sprayed in a suitable manner along the entire extent of the height of the elements 3 to be coated, this height also quite possibly considerably is.
    The series of electrostatic spray guns 4 spray substantially the side surfaces ac and the back surface d of the elements to be coated 3 with the coating powders, while the series of electrostatic spray guns 5 substantially the side surfaces ac and the front surface b of the elements to be coated 3 sprayed with the coating powders.
    Advantageously, the spray guns of each row spray 4 and 5 powders from the two opposite sides, but so that even the powder clouds, which are sprayed out of the spray nozzles against constantly arranged, are always opposite, since at the opposite sides of the overhead conveying synchronously move mounted spray guns (which are therefore facing opposite sides of the workpieces to be coated) and are always aligned in height, d. that is, they are at the same height during the process of applying the powder. This aspect is essential because it has the advantage of "dipping" the workpieces in the spray phase into a powder cloud fed by the spray guns spraying from the two sides.
    In addition, the speed of the airborne powder particles is significantly reduced, due to the fact that the air currents that promote the powder, are opposed and therefore repel each other. There are two possibilities: When the air and powder stream flowing out of a spray gun hits the workpiece, this stream flows against the workpiece and the powder that does not adhere directly to the workpiece bounces off and contributes to the formation of the powder cloud around the workpiece , On the other hand, if the air and powder flow does not strike a work piece, this is due to the fact that the two counter-free flow streams meet between two adjacent profiles and therefore repel each other, releasing powder due to the low velocity of the air which floats it by electrostatic attraction easily adheres to the side surfaces (the "inside" side surfaces which face each other) of the two adjacent workpieces, and this creates an ideal state of "availability" of the powder, whereby the possibility exists, the orders of the To optimize powder on the workpieces, d. h. to increase the amount of powder adhered to the workpieces.
    A vertical suction inlet 6 of the cabin air supply system is suitably mounted at the apex A of the cabin, substantially along the entire cabin height, and has horizontal and vertical sections which are adjusted by means of movable baffles and suitable movement and control systems which are indicated schematically in the plates by 21.
    Flow and velocity of the extracted air and the vertical position within the limits of the height of the coating booth can be calibrated so advantageously, also in terms of size and dimensions of the elements to be coated.
    The concentration of the air stream extracted in the cabin and the remaining coating powders which have not deposited directly on the elements 3 to be coated, flows through only a vertical suction inlet 6, which is positioned at the apex A of the triangular cross-section of the cabin the elements 3 to be coated on approaching the vertex A and on the removal and advantageously increases the deposition on the elements to be coated of the remaining portion of the coating powder, not by the direct action of the rows of electrostatic spray guns 4 and 5 by means of the nozzles 4a and 5a and floating in the air in the cabin.
    The outer and inner walls of the car, which limit the path of the conveyor 2, consist of suitable plates with closed cross section of plastic material 7, which are inserted on motorized rollers 8 and are tightened by this, causing their rotation. The proportion of the excess coating powder deposited on the walls is recovered by means of a scraper 9 which, by appropriately scraping off the flexible material of the plate 7, removes the coating powder and introduces it into a special collection and recovery system.
    At the bottom of the booth 10 are suitable section elements 11 which, when moved in a suitable manner, collect the excess coating powder which may have accumulated on the floor and introduce it into the collection and recovery system.
    It should also be noted that the special geometry of the cabin in a narrow V-shape together with the travel of the overhead conveying system 2 in the cabin it advantageously allows the guided through the cabin to be coated elements 3 directly from the rows of electrostatic Spray guns 4 and 5 are sprayed, and that the coating powder, which has not deposited directly on the elements to be coated 3, is guided to the vertical suction inlet 6 in the vertex A of the V-shaped outline and meets the continuous "profile arrangement" before it is extracted by the air extraction system of the cabin.
    For the same sprayed amount of powder, the proportion of coating powder which deposits directly on the elements 3 to be coated during the passage through the coating booth, advantageously considerably, which leads to increase the coating quality and the efficiency of the system and also increases the proportion of Powder, which is recovered by the ventilation and filtration system of the cabin. As already mentioned, the air in the cabin is exhausted by a cyclone separator 20 connected to a suction inlet 6 with a vertical axis located in the vertex A of the V-shaped outline, which has a variable geometry and thus allows the height to change on which the suction is concentrated, based on the dimensional characteristics of the elements to be coated.
    In the same amount of sprayed powder proves in this way the concentration of the coating powder, which do not deposit and remain in the air in the cabin, as limited and thus more easily controllable for the sake of safety.
    Compared to the number normally used, each row 4 and 5 may have fewer electrostatic spray guns, resulting in significant advantages in terms of the amount of air to be extracted and thus the performance of the mammalian fan.
    Although the cabin is of the "open" type, the coating powder does not escape from the coating booth because with the same amount of powder sprayed, the amount of coating powder that remains floating and does not deposit on the elements to be coated is limited Air supply system through the suction inlet 6 with a variable geometry may have a lower performance and be particularly efficient. The coating booth remains essentially clean, as with the same amount of powder sprayed, there is a limited amount of excess coating powder that has not been deposited. Cleaning the system to change the color of the coating powders is fast, and normally, the personnel responsible for it does not need to enter the coating booth.
    In addition, due to the high amount of deposited coating powder, the coating powder consumption is advantageously reduced in the phases of cross-flow start at the start of a new batch of elements to be coated. This is also true when using special coating powders which do not allow easy recovery of the coating powder by the system for aeration and filtration of the air in the cabin, as well as in special coating powders where the recovery is not advisable since the recovered quantities would have properties that are too different from the original coating powder.
    In view of the high amount of deposited coating powder, the coating quality is generally advantageously improved, due to the fact that predominantly the original coating powder is deposited, which does not originate from the recovery process, and thus has more controlled physical-chemical properties.
    Due to the arrangement of the rows of electrostatic spray guns on both sides of the overhead conveying system, the two main sides of the elements to be coated 3 can be adequately coated without having to use rotatable hooks. The spray nozzle 4a and 5a of each spray gun can also be suitably inclined, so that the penetration of the coating at the corners and grooves of the elements 3 to be coated is improved and the inclination of the beam to the side of the elements 3 to be coated makes it possible that their Corners are coated appropriately. The V-shaped walls of the cabin, consisting of closed-section plates of plastic material 7, fitted on and motorized by rotatable rollers 8, are continuously cleaned by the scraper 9 and the powder removed from the walls can pass over a suitable conveying and collecting system to be recovered.
    Due to the intelligent and calibrated handling of the inlet through the suction inlet 6, the bottom of the cabin 10 remains almost completely clean, and in any case even the ground powder can be recovered thanks to suitable sector knives 11 by a suitable conveying and collecting system.
    The roof of the cabin represents the most critical area with regard to the risk of leakage of the coating powder, which has not deposited on the elements 3 to be coated and floats in the air of the cabin. However, due to the variable suction through the suction inlet 6 in the cabin according to the invention, the suction can also be concentrated in the upper part of the suction inlet, so that the coating powder, which has not deposited, can be sucked off before it emerges from the roof.
    The operation of the coating booth results clearly from the previous descriptions and representations.
    In particular, the elements 3 to be coated meet a first row of electrostatic spray guns 4 and nozzles 4a with spray guns on both sides as they are guided along the approach path to the suction inlet 6. The suitably sprayed powders flow against the lateral surfaces ac and the back surface d of the elements 3 to be coated. Once they have passed the innermost turn of the cab, the elements 3 to be coated begin the discharge path while still in the cab, away from the suction inlet , and are passed through another area with a second row of electrostatic spray guns 5 and nozzles 5a, with spray guns spraying from both sides. The side surfaces ac and the front surface d of the elements to be coated 3 expediently receive the coating powder directly, which is due to the suitable inclination of the nozzle 5a, as well as the so-called cascade effect, with the result that all four surfaces abcd coating elements 3 are suitably coated with coating powder, even if their geometry is difficult to coat.
    Variations and variations with respect to the geometry of the cabin are of course possible, based on the geometric properties of the elements to be coated, the physico-chemical characteristics of the coating powder and the properties of the complete coating cycle.
    In practice, it has been found that a coating booth according to the invention proves to be particularly advantageous because it offers a special geometry in a narrow V-shape, which together with the way that follows the overhead conveying system in the cabin, it to coating elements, which are passed through the cabin, advantageously allows to be sprayed directly, wherein the coating powder, which has not deposited directly on the elements to be coated, is guided to the vertical suction inlet.
    The coating booth designed in this way can be embodied in numerous embodiments and variants, all of which fall under the inventive concept. All details can also be replaced by technically equivalent elements.
    The materials employed as well as the dimensions and proportions may be of virtually any type according to the requirements and the state of the art.
