Definitions

  • the invention relates to paining equipment, in particular spray painting equipment.
  • the paint spray equipment is located in a paint booth and suitable for automatic operation, for example the use of a paint robot.
  • the automatic operation requires paint supply in sufficient quantity under controlled process conditions.
  • the quantity of the paint supplied to the paint spray nozzle, the temperature of the paint and the pressure of the compressed air are the most important parameters to watch for.
  • a rise in the temperature of the paint usually lowers the viscosity and allows to apply paints with higher solid content. Therefore it is proposed to heat the paint and the compressed air prior to the spray nozzle.
  • the application of heat reduces the viscosity of the liquid product.
  • the decrease in viscosity reduces the forces to atomize and break up the liquid into smaller particles.
  • the objective of the invention is to create a spray of insecticide of very small droplets or particles in order to achieve a dense fog.
  • a precisely defined temperature of the sprayed product is not necessary as the product is not required to adhere homogeneously on a solid surface, therefore no precise temperature regulation needs to be employed for this particular case.
  • US6183161 discloses a paint spraying equipment in which the paint is heated by exhaust gases from an engine whereby the paint is not in direct contact with the exhaust gases. The heating of the paint lowers the viscosity and therefore the quantity of solvent added to the paint can be reduced.
  • a paint flow control valve and a temperature control of the heating medium are necessary to act simultaneously as not only 2 cases can occur but a whole range of supply quantities must be covered.
  • GB700595 represents the state of the art and provides a possibility to heat paint for continuous and intermittent operation.
  • the paint passes through a coil in a vessel filled with hot water.
  • a coil for compressed air and a coil for steam are arranged in the water bath.
  • the water may be heated by the steam passing through the coil or by an electrical resistance heater. Due to the considerable amount of water present in the vessel, the heating of the water is rather time-consuming.
  • FR1252974 provides an alternative solution for the preheating of paints for a spray gun.
  • the paint is preheated by compressed air from a compressor.
  • the hot air from the compressor passes along serpentines around the paint before being introduced into the spray nozzle.
  • a similar concept is proposed in GB161738, where the constructive details of such a preheating system are shown.
  • the preheating of the paint is achieved in FR1252974 only in the nozzle area and in GB161738 additionally in the paint reservoir connected to the spray gun. None of the 2 disclosures provides a control of the air temperature of the air circulating in the nozzle area and/or around the paint reservoir. Consequently the application of the paint on a large surface may not be uniform due to uncontrollable temperature variations.
  • this invention relates to equipment for application of paints, in particular for paints containing solvents. It equally applies to mixtures of several different compounds making up a painting mixture.
  • the paint or paint mixture is heated in order to lower the viscosity of the paint which allows to employ higher viscosity paints. Consequently the number of paint layers - that means the number of repeated paint application processes - can be reduced.
  • An additional advantage of the application of paints containing a higher percentage of solids results in the reduction of solvent content.
  • a further advantage compared to the prior art is the possibility to maintain the heating or cooling medium temperature close to the paint temperature.
  • a temperature difference of only 5 °C between paint and the heating or cooling medium may be realized with air or another gas as heating or cooling medium.
  • a liquid heat exchanger such as an oil / paint heat exchanging system
  • the response to temperature changes is much shorter due to the minimum temperature differences.
  • the heater and pump required for a heat exchanging system based on liquids, such as oil do not only add to the cost of the equipment but also may cause problems in an environment subject to explosion risks.
  • any change in paint temperature may be signaled immediately to the control system, but the time to change the temperature of the oil and the time to pump the oil to the heat exchanger add to the response time.
  • the heat exchanger uses air or another gas as a medium substantially at the same temperature as the paint.
  • the air flow controlled by a ventilator installed outside the booth is subject to much less inertia than the liquid flow. Except the ventilator motor and the compressor, no electrical equipment is present in the paint cabin, which eliminates explosion risks altogether.
  • compressors, ventilators and their motors are anyway installed outside the paint booth, or at least in a room separated from the paint booth.
  • a further advantage of the invention is the possibility to paint large surfaces in a constant and repeatable quality. Due to the precise temperature control, a constant thickness of the paint layer may be obtained by a completely automated the painting process. In said painting process, the paint may be applied in a paint booth by one or more robots. Only in an automatic process, these accurate temperature and flow conditions of the paint and the pressurized air can be realized and maintained over a large series of parts. All of the cited prior art solutions deal with a manual or batch application of the paint, consequently the problems of a continuous operation do either not arise for small series or have to be circumvented by elaborate valving and switching equipment. Consequently the solutions of the prior art are not deemed to be suitable for a continuous painting operation especially for pieces with large surfaces, such as automotive exteriors.
  • the painting process In order to paint large surfaces in a constant and repeatable quality, the painting process needs to be completely automatic.
  • the quality of the paint surface is determined by the thickness of the paint layer as well as the constant operating conditions when processing a paint batch. Therefore the paint is advantageously applied in a paint booth by one or more robots. Consequently accurate temperature and flow conditions of the paint and the pressurized air may be realized.
  • the automatic paint processing usually leads to continuous paint application processes. Problems may arise, during the change of paint batch or paint composition. Critical situations may arise during each start-up and shut down of the process which requires careful planning of batch size and part geometry.
  • the paint process comprises the following steps: charging the conveyor means, e.g. skids, cleaning, usually with water based cleaning agents, rinsing with water and drying, increasing the surface tension of the thermoplastic piece by oxidation or fluorisation to substitute C-H by C-O or C-F by flame application, corona application, plasma or fluor gas treatment, as a subsequent step a primer application eventually together with a agent for promoting adhesion (e.g. for PP substrate), application of the basis paint composition, IR-heating, application of the clear coat, IR heating, drying and final cooling.
  • the paint is applied usually at temperatures, that differ substantially from the ambient conditions.
  • the heat exchanger provided for this purpose is arranged externally to the paint spray head and preferably outside the paint booth for reasons of explosion risk.
  • the dimensions of the heat exchanger are calculated as a function of the paint quantity and determine size and heat exchanging surface.
  • the heat transfer by conduction and/or convection may be achieved by air or water or other heat transfer fluid.
  • the temperature sensors are connected to a PLC.
  • the PLC compares the value of the temperatures with a preprogrammed value for the paint composition in use. Consequently the PLC sends a signal to the resistance heaters.
  • the resistance heaters generate heat by transforming electrical power into heat e.g. by heating a metallic strip or coil whereby the electrical power input may be translated into a series of current impulses.
  • the frequency of these impulses may be changed, which results in a variation of the heating capacity.
  • the PLC signal therefore enables the frequency change which eventually results in the temperature change of the hot air entering the heat exchanger.
  • the PLC may emit a signal to act on the of flow rate of the heat exchange fluid.
  • the flow rate of the heat exchanging fluid may be determined by a ventilator, driven by an electrical motor with variable rotational speed.
  • the rotational speed may also be determined by pulsed signals (e.g. stepper motor).
  • the signal emitted from the PLC results in a frequency change of the motor speed and therefore a change in air flow rate.
  • the change of flow rate of the air supply changes the residence time of the air in the heat exchanger. Increased air flow results in increased heat transfer.
  • the components may be heated separately in the same heat exchanger and may be mixed just prior to the application point.
  • a separate coil may be used, the coils are arranged in parallel either by attaching them or by arranging one or more coils in another coil, so that the diameter of the paint coils is smaller or larger as the diameter of the pressurized air coil, depending on the necessary overall length of the heat exchanging surface, which is equal to the coil surface.
  • the invention is suitable for being mounted to a paint robot. In the case of mixing more than one component the mixer may be located also in the robot arm.
  • the heat exchanger may be connected to the pulverization means (spray nozzle) by flexible conducts such as hoses, which are thermally insulated.
  • the heat exchanger may be placed also outside the paint booth, which allows for better accessibility in case of maintenance or in case of colour or paint composition change.
  • the heating of the paint allows the use of paints with high solid content. Consequently the solvent content decreases.
  • paints with a solid content of 60 to 70% are applied onto parts in one or more process steps.
  • the high viscosity of the paints made the use of high spraying pressures necessary, which caused difficulties to obtain homogeneous painted surfaces.
  • a further advantage is the reduction of paint layers per painted part, in many cases, the number of painting layers can be reduced to only one a single painting layer.
  • the operation at elevated temperature makes the paint equipment easier to clean, as clogging of the paint can be avoided due to the reduced viscosity at the elevated temperature.
  • the temperature is kept constantly close to operating temperature, so that the changeover to another paint product or composition is effectuated at operating temperature. Due to the lower solvent content, an increase in brilliance and better surface covering and reduction of the "orange peel" effect could be obtained.
  • the amount of solvent molecules, that have to pass the paint layer before evaporation decreases, therefore the disturbance of the paint surface may be kept at a minimum, which results in a more homogeneous surface resulting in an improvement in gloss and optical appearance.
  • Further advantages by the invention are a reduction of emissions of volatile compounds due to reduction of solvent content and therefore improved overall compatibility of the process with environment and health regulations.
  • the process may be used with conventional painting equipment and may be applied for products on solvent or water based coats. Any application conditions, such as seasonal temperature changes, affect paint quality less as the temperature can be controlled much more precisely.
  • Fig. 1 shows the painting equipment schematically.
  • the painting equipment consists of a gun, 1 a heat exchanger 2, a hot air generator 3 and an air compressor 4.
  • the air compressor 4 and the hot air generator 3 are located outside of the painting cabin 5.
  • the hot air is circulated through the heat exchanger located within the painting cabin.
  • the heat exchanger houses the tubes for the pressurized air 6 and the paint supply line 7.
  • the paint supply line transports paint from the paint container 8.
  • the paint supply line enters the heat exchanger in point 9 and leaves it at point 10.
  • the paint is stored in storage containers located outside of the paint booth to allow for unproblematic refilling and color substitution.
  • the paint transport is either done by gravity or by pumping.
  • a paint pump 18 is shown schematically in paint supply line 9.
  • the heat exchanger consists of a vessel 11, preferably a cylindrical vessel.
  • the hot air supply 14 tube is welded or flanged to the vessel on one end of the vessel 11, the hot air discharge tube15 is welded or flanged to the vessel on the opposite end of the vessel 11, so as to provide a countercurrent flow.
  • the pressurized air supply 16 enters the heat exchanger in the area of prechamber 13 and exits the heat exchanger in the area of prechamber 12.
  • the pressurized air and the paint circulate in separate conduits.
  • the conduits may have one or more coils as shown in fig. 3, so that the paint heats up when flowing through the tubes in the heat exchanger.
  • the compressed air for the spray nozzle is preheated in a separate coil tube.
  • a straight tube may be sufficient, but if temperatures up to 60 °C are necessary for lowering the viscosity of paints with high solid content, the heat exchanger would simply assume a length dimension which is difficult and costly to produce, if no coils are provided.
  • a temperature sensor in the flow path of the paint and preferably also in the flow path of the pressurized air. The measured temperatures are fed into a control unit 19, such as a PLC.
  • the PLC determines the air requirement to achieve the desired heating effect and actuates a variable flow restrictor, such as a throttle valve 20, or changes the rotational speed of the motor of the air ventilator 21.
  • a variable flow restrictor such as a throttle valve 20, or changes the rotational speed of the motor of the air ventilator 21.
  • the power of the electrical resistance heater 22 may be regulated.
  • a combination of the control alternatives may be foreseen so as to respond to different signal response speed requirements depending on the variation of the temperature difference to be regulated.
  • Fig. 3 shows a possible arrangement of the coils 23.
  • the coils 23 are preferably made from stainless steel and for the paint application it has to be ensured that the surface roughness of the internal surface in contact with the paint is low enough in order to avoid clogging of paint particles.
  • Fig. 4a,b,c show a variety of coil arrangements.
  • a whole range of different coil arrangements in the heat exchanger may be used.
  • the different heat exchangers may also be part of a modular equipment.
  • a different heat exchanger is attached to the spray gun. If the external dimensions of the heat exchanger are fixed due to assembly constraints, the heat exchanging surface can be modified by variation of coil length.
  • Fig. 4a shows an example in which the paint coil 24 fills the space inside of the pressurized air coil 26 over the whole length of the heat exchanger. Paint coil 24 and pressurized air coil 26 are mounted concentrically to each other.
  • Fig. 4b shows an example with a paint coil not covering the whole space within the heat exchanger.
  • Fig. 4c shows a heat exchanger with multiple paint coils.
  • the 2 coils shown in this embodiment serve only as an example. It is possible to arrange more than 2 coils concentrically within each other or use only a fraction of the available space for small coils.

  • a paint mixing device 27 between heat exchanger and spray gun.
  • Various types of heat exchangers such as those disclosed in Fig. 4a,b,c may be assembled onto the robot. This allows for a fast change in paint composition and allows the cleaning of the heat exchanger not in use without interrupting production.

The temperature sensors 28 and 30 located at the paint and pressurized air entries respectively provide information about the incoming temperature.
  • the signal sent to PLC 19 is evaluated by a program and determines the quantity and temperature of the hot air to be supplied.
  • the final value of the paint and hot air are stored in the program. It may either be programmed by a user or coming from a process controller (not shown) having stored all parameters concerning the application of any paint type.
  • the temperature sensors 29 and 31 measure the temperatures on the paint and pressurized air discharge and feed the value into the PLC.
  • the program in the PLC controls the calculated temperature with reference to the measured temperatures and issues a visible or audible alarm in case of exceeding the set tolerances.
  • the part to be painted such as an automotive exterior or interior part, is coated with a clear coat. Alternatively, a 2K- coating can be applied.
