Definitions

  • the present invention relates to a coating apparatus applicable to coating booths mainly although not exclusively used in the sector of treating leathers or other materials using machines of the rotary turntable type or alternative, to which numerous automatic airbrushes are applied.
  • the actuated machine allows the introduction of a single flow of hot air with various airbrushes connected to the distribution system of the air called the working fluid.
  • Such heated working fluid is introduced through an insulated conduit which is located on the supporting part of the rotating turntable, which then continues towards the airbrushes through a tube that is also insulated, having dimensions adapted to the necessary flow of working air, ending directly at the airbrush, obtaining rather higher performance results with respect to traditional applications that use unheated working air, with important improvements in the application of the coatings on the objects to be treated.
  • the system according to the invention is applied in the sector of coating leathers but can also be advantageously used in the sector of wood or ceramic, through relevant similar machines in which numerous airbrushes are installed, the number of which will vary according to whether they are leather or wood or ceramic coating processes.
  • Automatic spray coating systems are known and have been used for some time, both of the electrostatic and traditional type, in which liquid coatings are dispensed by spraying towards objects of various kinds.
  • Automatic spray coating systems use compressed air as the working fluid for atomising the coating so that it can be deposited onto different types of surfaces uniformly, e.g. on leather, wooden objects, or made of ceramic or other materials.
  • Traditional pneumatic spray coating systems for leathers but, more generally, also other products, comprise a coating booth inside which a conveyor belt with a horizontal arrangement runs on which the leathers are placed so that they can be moved along an advancement direction and according to a predefined conveying speed.
  • a rotating turntable is arranged, placed on a circular axis of rotation synchronised with the advancement of the leathers.
  • a plurality of spray guns is applied to said turntable, which are placed at regular distances from each other along the peripheral area of the turntable itself and facing towards the conveyor belt, so as to be able to apply the coating onto the leathers or other parts that are advancing while the turntable rotates at a predefined rotation speed.
  • the turntable while rotating, allows the vertically installed airbrushes to spray the coating onto the parts to be coated, dispensing the product in a fan-like way onto said parts.
  • the airbrushes are managed automatically and separately from each other by an electronic control, whereas the compressed air used during atomisation is taken from the dedicated circuit.
  • Compressed air represents the working fluid coming from a general compressed air line and passing through a variable pressure regulator, and conveyed air filtration.
  • the traditional type of filters that are used for filtering the compressed air use separating cartridges made of fibre, to be able to dehumidify the air through pressure absorption, and remove any oily particles and/or residues of hydrocarbons obtaining compressed, filtered and dehumidified air.
  • the flow rate of traditional compressed air systems for coating systems can also be very variable and in the event of only one airbrush the consumption of working air can reach about 900 n/1 minute, considered an optimal consumption, but only by traditional standards.
  • the present invention sets out to provide a machine for a booth that uses various airbrushes connected by means of a dedicated hot air feed conduit to guarantee high flow rates, so as to be able to serve various spray guns with a single heating system, in order to eliminate or at least dramatically reduce the drawbacks highlighted above .
  • the air introduced through the feed circuit crosses a heating system that can increase the temperature thereof and improve the application of the coatings to parts, thus creating an optimal condition for the purpose of the quality of the result obtained.
  • Such working air flow heating system conveying in the insulated conduit related to the atomisation of the airbrushes, crosses a heating device which, as well as comprising a filtering and dehumidifying system, is adapted to dispense hot air through the distribution conduit positioned above the rotary turntable.
  • the air treated through filtering and heating offers the ideal working conditions for the coating airbrushes, by placing the installed heating system in the condition to be able to also withstand the load of various airbrushes activated simultaneously.
  • the invention further sets out to lower the viscosity of the coating through the exchange that takes place when the product is split up with the heated atomisation working air, with a consequent reduction of the quantity of air used and therefore lower waste of dispensed coating and a significant increase in the transfer index, whose value can even reach 90%.
  • the dependent claims of the present solution outline advantageous embodiments of the invention.
  • the main advantage of this solution relates to the fact that the coating system according to the invention makes it possible on one hand to perform coating operations reducing the waste of materials and means to a minimum, and on the other to reach rather higher qualitative results than those that can be obtained with traditional cold air systems.
  • figure 1 represents a schematic and perspective view highlighting the conformation of a coating system comprising the treatment means for the optimisation of the working fluid relative to the compressed air
  • figure 2 illustrates a schematic view highlighting a plan view of a rotary turntable

  • figure 6 is a schematic sectional view of the air treatment device with the lines of the path of the air internally thereto.
  • 10 generally indicates a coating system according to the invention as a whole .
  • the coating system 10 comprises a conveyor belt 11 adapted to move the articles undergoing coating along a substantially horizontal advancement direction, so that from the spraying area the coated articles can be conveyed towards a drying oven indicated overall with 12.
  • the system 10 comprises a rotary turntable 13 represented in a plan view in figure 2, which is located on a frame above the conveyor belt 11 and is rotatable according to an axis of rotation orthogonal to a plane of the conveyor 11 itself on which the leathers or other articles to be coated lie and are moved .
  • the rotary turntable 13 comprises a plurality of spray guns 14 for spraying the coating, said guns 14 being mounted along the outer circumference of the turntable 13, in the example illustrated in figure 2, each of them is positioned on the end of arms 15 extending radially with respect to the axis of rotation.
  • the spray guns 14 are positioned on the end of conduits coming from a compressed air line 16, one of the hoses 17 thereof forms the conduit 18 that enters the turntable with the conduit 19 and branches off inside the turntable into the various channels for each gun.
  • a device 20 which represents the main characteristic of the invention as it constitutes the element for heating and filtering the air introduced into the guns 14.
  • the device 20 comprises an external tube 21, an internal heating tube 22, which, in turn, internally comprises a group of electrical heating elements 23.
  • the device 20 is equipped, at its lower base, with a bottom cover 24, whereas at the top it is closed by a cap or head 25.
  • the cap 25 is provided with an air inlet hole 26, an air outlet hole 27, and a plurality of smaller holes 28 suitable for passage of cables and feed probes.
  • the device 20 comprises spaces afforded between the external tube 21 and the internal heating tube 22, the latter, in turn, being provided with windows 29 in the lower part thereof, for passage of the air entering from the inlet 26 and exiting from the outlet 27.
  • the device 20 is equipped internally with electrical heating elements 23 located in proximity to the respective dissipaters that are licked by the air passing into the device and conveyed towards the guns 14.
  • the system thus described is commanded and controlled by a computerised control unit that controls all of the operating parameters that have been set and particularly the air temperature that has been set and is necessary for correct use of the system, by acting on the activation and deactivation of the heating elements.
  • the device 20 is newly conceived in this sector and is applied to the compressed air inlet 19 that feeds the complete machine, and the total air consumption of such machine notably exceeds the flow rate of the machines currently on the market, as the indicative rated consumption for 12 guns is around 6500/7000 nl/h.
  • a further characteristic of the invention comes from the presence of insulated working air conduits. Such conduits start from the heating device 20, pass through the distribution manifold 31 shown in figures 1 and 2, to be connected with the distribution conduit 15, also insulated, which feeds each individual gun.
  • the air at the inlet enters the device 20 at room temperature.
  • the electronic control system Based on the temperature measurement of the exiting air detected by the thermistor, the electronic control system compares this value with the value entered by the user and adjusts the activation and deactivation of the heating elements in a continuous modulation mode with an indicative absorption of around 16 A.
  • the elements are switched on and off by means of a feedback (or “tracking") control that constantly compares the value just read with the objective value, in an attempt to bring the magnitudes of interest towards such value, with a typically asymptotic trend or characterised by small oscillations.
  • a feedback or “tracking” control that constantly compares the value just read with the objective value, in an attempt to bring the magnitudes of interest towards such value, with a typically asymptotic trend or characterised by small oscillations.
  • the adjustment parameters are, in this case, all the possible ones: proportional, integral and derivative (PID type control) .
  • the elements are not supplied or cut off according to the start-stop modes typical of common thermostats, as PID control allows continuous adjustment and with a small hysteresis range.
  • the elements are supplied by a solid state static relay, controlled by the control board with PWM logic, which sends them high frequency voltage pulses with a variable duration of each pulse, according to the temperature difference measured between the outlet air and the set value.
  • the modulation takes place based on times of 2 msec with a variable work cycle from 0 to 100%, with minimum variations of 0.5%.
  • PID adjustment determines the activation percentage of the static relay (0-100%) according to the relationship :
  • TSET - T ARIA is the difference between the set temperature and the temperature of the air to be controlled .
  • Kp the proportional action constant, as the latter increases the action connected with an instantaneous difference between the measured temperature and the setpoint value increases.
  • the coating system according to the invention allows a sufficient flow rate to be obtained so that the booth and therefore also the guns for the air heated and filtered from all impurities, are treated so as to:
  • the reduced viscosity allows a reduction of the air used for spraying "coating" products; the reduction in the air pressure in this case is 30% with respect to normal conditions;
  • an auxiliary heating unit (33) is inserted along said conduit (18) that enters the turntable (13) through the conduit (19) for branching off into the latter in the various channels of each spray gun (14) and downstream of said device (20).
