    DK 2019 00041 U1
    The object of the invention
    It is an object of the utility model application under consideration to protect people working in or around a spray booth.
    It is a further object of the utility model application during treatment to reduce pollution during operation of a spray booth.
    Description of the Invention
    This object can be accomplished with a control system of the type described in the introduction and in the preamble of claim 1, which is in particular that the control system is adapted to stop the spraying based on a maximum spray period and a detected maximum VOC level. .
    This ensures that the spray booth can be operated without polluting the outside environment. At the same time, the operation of the spray booth by the staff will be carried out in a very safe manner, because the VOC level can be kept at a relatively low level in the spray booth while operating any staff. This can be very effective when painting cars where only small parts of the car need to be painted. In this way, it is further efficient that the car can be placed in the spray booth and all preparation is done automatically until the spraying process has been performed manually. Because there is a control of the maximum spray period and also the VOC level during spraying, it is possible for the system to stop spraying, for example after five minutes, and also stop spraying if the VOC level is rising above a defined level.
    In a preferred embodiment of the invention, the control system comprises light sources where at least some of the light sources are adapted to shut down during spraying and as many as possible of other power consuming devices.
    This can reduce the power consumption of the spray booth, but the primary reason for switching off many other consumables is for safety reasons. Heating elements must not be used because there is a risk of sparks which could be dangerous due to the risk of explosion.
    DK 2019 00041 U1
    In addition, an interruption of the light sources is a security that forces an operator to leave the spray booth. Before the light source is switched off, a flash of light is established as a warning that the light sources will be completely switched off shortly.
    Furthermore, there is no need for more light than the light needed to spray. Therefore, most of the light can be turned off for the same reason.
    The only force to be used during spraying is the power supply to generate compressed air for spraying and for ventilation. Since ventilation is performed with switch-mode control of the electric motors, these motors can be designed as asynchronous electric motors, where the possibility of generating sparks is completely avoided simply because there is no electrical connection between the stator and the rotor.
    In a preferred embodiment of the invention, the control system comprises at least a first pressure sensor located at the input of the filter system, which control system comprises at least a second pressure sensor located at the output of the filter system.
    The system calculates the pressure difference between the first and second pressure sensors to calculate the filter status. This allows the control system to have almost complete control over the status of the filter system. The pressure difference will always be a good indication of the effectiveness of any filtering and indicate when the next filter replacement should be performed. In this way, the system is able to predict when the next filter replacement should be performed and in some situations it will be possible for the control system to simply refuse the start of the process until the filter is replaced. It is possible, for example, by active carbon filtration to reduce the level of VOC, but other filtration methods also appear to be possible. A filter that uses a combination of adding ozone and UV light should be able to reduce the VOC content almost completely by changing the chemical structure of the VOC to environmentally friendly components.
    In a further preferred embodiment of the invention, the spray device may be connected to an air supply through a supply line, which supply
    At least one solenoid valve for on / off control, which solenoid valve is controlled by the control system.
    Hereby it is achieved that traditional spraying equipment which uses compressed air to spray the paint during spraying is controlled by the control system because the solenoid valve must be open before any pressure is applied to the spraying unit. The control system thus has full control over the spraying process. In this way, it is possible that the VOC level in the spray booth must be at a low level before spraying is started, simply because the solenoid valve is closed until the correct VOC level is achieved. Further, by increasing the VOC level to a safety level where there is a risk to the operators, the solenoid valve will simply close and stop the spraying process.
    In a further preferred embodiment of the invention, the control system comprises an inlet fan arranged to control by frequency modulation of the power supply to a fan motor that a VOC sensor adapted to measure the VOC level in the inlet air is connected to the control system.
    In this way, it can be achieved that the unit which performs the frequency modulation is also able to monitor the power supply of the fan motor, thus communicating back to the control system if there is any deviation from normal in the power consumption of the fan motor. In the same way, it is of course possible to recall the frequency that drives the motor, thus providing the system with information relating to the fan speed. Similarly, the VOC level can be measured.
    In a further preferred embodiment of the invention, the control system comprises one or more outlet fans arranged to be controlled by frequency modulation of the power supply to a fan motor, comprising a VOC sensor adapted to measure the VOC level in the outlet air, which VOC sensor is connected to the operating system.
    As previously explained / described, it is possible to measure the engine speed from the control system as well as the engine power consumption. Therefore, the operation of the outlet fan is possible. The outlet fan is as important as controlling the inlet fan, because by controlling both ventilation systems it is also possible to control the current pressure in
    DK 2019 00041 U1 spray booth. This prevents VOC gases from leaving the spray booth through walls or roofs or through smaller openings. By keeping the internal pressure in the spray booth lower than the external pressure.
    In a further preferred embodiment of the invention, the control system comprises the inlet fan and the outlet fan adapted to increase the generated air flow during the spraying period and continue after the spraying operation during a vaporization period until a decreasing VOC level is detected.
    Hereby, it can be achieved that by increasing the velocity of the ventilation system, the VOC level is reduced during the spraying period and also just after the spraying, because there is an evaporation for a few minutes after the spraying is completed. This is very important during the evaporation period that as many of the VOC gases are sent to the filters as quickly as possible. After evaporation of the volatile gases and the VOC level is reduced, it is possible to reduce the rate of ventilation. It is further possible to let the VOC level more or less control the level of ventilation.
    In a further preferred embodiment of the invention, the filter system comprises at least one activated carbon filter. This results in the fact that most of the VOC gases will be collected in the activated carbon filter. Further cleaning of the air contaminated by VOC gases could be done by a combination of ultraviolet light and the addition of ozone to the air passing through the filter.
    In a further preferred embodiment of the invention, the control system may comprise an air flow measuring device for measuring air flow at least through the activated carbon filter. Hereby it can be achieved that the status of the activated carbon filter is under direct control by measuring the actual air flow through the activated carbon filter.
    In a further preferred embodiment of the invention, the air flow measuring device is a thermal flow sensor. In this way it can be achieved that the air flow will reduce the temperature of a heated cable, where the resistance of the cable depends on the temperature and the temperature changes the resistance and the cable. The resistor can be transferred to the system to indicate the air flow.
    DK 2019 00041 U1
    In a further preferred embodiment of the invention, the air flow measuring device is an ultrasonic air flow meter comprising one or more ultrasonic transducers to generate an ultrasonic signal in the air flow. This allows the air flow to be measured through the activated carbon filter and the actual air flow can be transferred to the system. A system for measuring air flow in an air duct is published in WO 2014/202084.
    In a further preferred embodiment of the invention, the control system comprises a one-touch cabin function switch. In this way it can be achieved that in the spray booth there is only one indication, as the one-touch cabin function switch when changing color can indicate different situations. Green means ready to spray, red can mean time to evacuate and finish spraying, and in this way, the one-touch cabin function switch is simply the only technical installation needed inside the spray booth.
    In a further preferred embodiment of the invention, the control system simply comprises the only technical installation. After finishing a spraying process, a drying process is necessary. Different kinds of paint need different types of heat treatment. It is therefore possible to use both infrared heating and ultraviolet light for heating. In many situations, a combination of the two different frequencies of radiation is performed. By locally heating a locally painted area, it is possible that the drying of the newly painted area can be completed in a relatively short period of time.
    In a further preferred embodiment of the invention, the control system comprises at least one grinding equipment. Hereby it is possible to monitor the grinding period that has been used and the operating system is able to compare the period used for the grinding with grinding periods stored on the server in the cloud-based database.
    In a further preferred embodiment of the invention, the control system is arranged to open and close a door or gate to access the spray booth. Hereby it can be achieved that the doors can only be opened in situations where the system accepts door openings, but also in emergency situations the control system will be able to open the doors or gates to have a rapid ventilation of the interior of a spray booth.
    DK 2019 00041 U1
    In a further preferred embodiment of the invention, the control system comprises one or more light drivers, which light drivers are connected to LED light sources. This results in the control system also controlling all the lights used inside the spray booth. The use of LED light is positive in that light or different frequencies can be obtained. Furthermore, the power consumption is reduced by the LEDs.
    In a further preferred embodiment of the invention, the spray booth may be a mobile spray booth for treating cars. This results in the fact that the spray booth may be made as a tent that can be easily moved from one position to another. This makes it possible for a short period of time to work with a spray booth, for example at a large parking area, where a number of cars must be measured in local areas.
    In a further preferred embodiment of the invention, the control system is arranged for processing which includes the following operating sequence in said order: grinding, priming, spraying, curing. This ensures that all the various functions are managed with the operating system and all activities are stored in the cloud-based database. In this way it can be further achieved that a documentation can be performed for each activity.
    In a further preferred embodiment of the invention, the control system is arranged to collect data for documentation and administration of the treatment. Hereby it is possible to obtain documentation for all the treatments performed in each of the syringe booths connected to the system. In this way, it will be possible to guarantee the treatment for all customers. In addition, it will be possible to perform statistical analyzes of how each spray booth works and who of the persons operating in the spray booth perform.
    In a further preferred embodiment of the invention, the control system is arranged to control at least the consumption of paints, varnishes and other consumables. Hereby, the data referring to the consumption of materials is also stored in the same cloud-based database.

    Detailed description of the invention
    FIG. 1 shows a sectional view of a possible spray booth 4 where the spray booth is cut and one looks into a part of the spray booth 4 where, for example, doors at both ends cannot be seen. In the walls of the spray booth 4, the activated carbon filters 52 are indicated; here stated inside the walls. Furthermore, UVA / IR heaters 56 and an inlet filter 88 are indicated. An explosive zone 82 is indicated inside the spray booth 4.
    During operation, an object, for example a car, will be placed inside the spray booth 4, and during all operation, doors will be closed and there will be an insulated climate inside the spray booth.
    Exhaust fans and also inlet fans regulate the climate inside the spray booth so that the pressure inside the spray booth is less than the pressure outside. This way, no VOC gases will leak from the spray booth.
    During the spray operation, an explosive zone will be found inside the spray booth, simply because the concentration of VOCs, along with dust from old paint that could occur inside the spray booth, will form a rather explosive atmosphere.
    DK 2019 00041 U1
    For example, to avoid any kind of explosion, the control system 2 is arranged to switch off the UVA / IR heater 56 during the spraying process. The control system 2 is further arranged to more or less switch off all other electrical consumables during the spraying process. The only technical installations that are in full operation are the VOC sensors and the ventilation means. In this way, it is possible to keep the VOC level inside the spray booth relatively low. As the VOC gases are passed through the activated carbon filters 52, almost all the VOC particles are held within the filters.
    FIG. 2 shows a control system 2 connected to a spray booth 4. The spray booth 4 comprises VOC detectors, where VOC means VOC which can be detected. Further, there is provided a ventilation system 8 which operates in connection with a filter system 12. FIG. 1 further shows a cloud-based database 20 and a spraying device 32, which spraying device 32 is connected to a supply line 36 which leads to a magnetic valve 38 which is controlled by the control system 2. The valve 38 is further connected to an air supply 34. Furthermore, indicating an inlet fan motor 42 and a VOC sensor 44. Both are connected to the control system 2. The figure also shows outlet fans 46 which operate with VOC sensors 50. All of these components are also directly connected to the control system 2. pressure cabin function switch 54, and a UVA / IR heater 56 are also indicated within the spray booth 4 and further abrasive equipment 58. The control system 2 is connected to a light control unit 62, which light control unit 62 is connected to a plurality of LED light sources 64. power supply 66 connected to the grinding equipment 58. Furthermore, a power supply 68 connected to UVA / IR heater 56. Further, FIG. 1 a customer online dashboard 70 and a support center 72.
    In operation, for example, a car may be placed in a spray booth 4, as a system of doors can be opened and the car may be placed in the spray booth 4. After the door is closed, the spray booth is an isolated climate zone where the VOC level is monitored by several VOC sensors . VOC sensors are mentioned as 6, 16, 44, 50, and in fact there are probably even more sensors. The VOC level is monitored by the various sensors, all connected to the operating system 2. All data collected in the operating system 2 is communicated to the cloud-based database 20 and the customer online dashboard 70 and to the support center 72. In operation, it is preferred that keep the pressure in the spray booth un
    GB 2019 00041 U1 that exterior pressure and in this way prevent some VOC gases leaking to the outside. During a spray operation in which spray equipment 32 is used, the VOC level but also the spray period is also measured. If the VOC level is above a limit, or if the spray period is above a limit, the magnetic valve 38 will be closed with a signal coming from the control system 2. The filter system 12 together with the ventilation system 8 will automatically reduce the VOC level after spraying has stopped, but In a very critical situation where, for example, the VOC level is rapidly increasing, evacuation may be necessary. The control system 2 further controls the inlet fan motor 42, where a VOC sensor 44 measures the inlet VOC level. Furthermore, a motor 46 for outlet air is indicated. Pressure sensors 22 and 26 measure the inlet pressure and the outlet pressure. Additional pressure indicators are used to measure the pressure difference over each filter used. In this way, it is possible to predict the life of the files. The control system 2 will also perform control via a light driver 62 which controls the number of LED sources 64. This allows the control system 2 to also control the light in the spray booth 4. Light control can be quite important, because if paint is done in different colors, it can be quite important to change the spectrum of light in the spray booth.
    FIG. 3 shows a possible embodiment of a filter system 12. Inlet ventilation means 74 indicate an inlet fan motor 42 which controls the inlet air. The VOC level of the inlet air is indicated by a sensor 44. Furthermore, outlet ventilation means 76 comprising outlet fans 46 driven by motors 48, wherein the VOC level is indicated by the VOC sensor 50. Furthermore, a pressure sensor 22 is provided. in the spray booth 4, and a pressure sensor 26 located outside the spray booth 4. Hereby the pressure difference can be indicated. Furthermore, in FIG. 2, an activated carbon filter 52 and an inlet filter 78 and an outlet pre-filter 80 are indicated.
    In operation, the inlet air is filtered and the amount of air is controlled by the fan motor 52, for example by frequency modulation. In this way, it is possible to perform speed control of the ventilation of the inlet air. Furthermore, the outlet air is controlled by ventilation 46 driven by a motor 48. This motor is also controlled by frequency modulation, and therefore the outlet fan speed can be set from the system 2. The outlet air is first pre-filtered through a pre-filter 80 before the outlet air is sent through the activated carbon filter 52. The outlet air 28 is then so clean that the VOC level can hardly be indicated.

    FIG. 4 indicates a circle with various functions indicating that system 2 is arranged to always operate in a circle as described. Starting with a standby 86 there will be a check indicated by a square until the next step which could be a preparation where a grinding operation or other form of preparation before painting is to be performed. This preparation must be completed and it must be checked before entering the next operating step, which is the spraying process 90. It should be noted that an external indicator arrow 84 is an evaporation indicating that during the spraying process an evaporation of VOCs is taking place. directly from the spraying process or from the surface being treated.
    There will be a high degree of evaporation of VOCs to be removed by the ventilation 94 which is also operating during preparation. At the end of the spraying process there will be a short waiting process because the evaporation period must be completed before the next step. Therefore, the VOC level must be accepted before entering the drying process 92.
    During the drying process 92, ventilation is still in operation. Ventilation is adjustable, so during the evaporation period there will be a much higher degree of ventilation, such as during drying, but even during this process some form of evaporation of VOCs will still occur from the painted surface. After the drying process, ventilation can be significantly stopped or reduced. The system can terminate where it starts in the standby situation. This standby process will reduce the power consumption of the system and the standby period may be very short if the next car is to be serviced or a new repair may need to be done on the other side of a car, then the standby function can be completed in a few minutes, or maybe it can wait until the next day.
    FIG. 5 shows a top view of a spray booth 4. This indicates that doors are closed and a closed volume is formed within the spray booth 4. The activated carbon filters 52 are indicated on the walls and at the top of the spray booth 4 an inlet fan 40 is indicated. which sends fresh air into the spray booth 4.
    In operation - when the doors are closed and spraying has started - an explosive zone 82 is formed inside the spray booth 4. This explosive zone exists as long as there is a relatively high VOC level in the spray booth 4. Therefore, many of the electrical consumables that works in the spray booth during spraying, off the system

    FIG. 6 shows the curvature of the VOC level during a possible spray sequence. The VOC level in the outlet 96 is indicated by the upper curve and the VOC level in the inlet is indicated by a lower curve 98. These two curves are more or less parallel at very low levels of VOC. A maximum VOC level 100 is specified, where the system is arranged to probably first send a warning to the personnel in the spray booth 4, and if the VOC level is still rising, the system is arranged to perform an automatic spraying interruption. Furthermore, the maximum spray period 102 is indicated.
    The spray booth is typically used for car repairs. Therefore, the spraying period will typically have a maximum of 10 minutes, and in many situations the spraying process is completed in less time.
    For safety reasons, an interruption occurs if the VOC level is above the safety level and also an automatic stop if the maximum spray period is reached.
    FIG. 7 indicates a curve for the VOC level at outlet 96, which curve increases over a very long period. In this way it is possible to specify the maximum service time for the activated carbon filters 52. The system also performs measurement of the pressure difference over the activated carbon filters 52. This information on increasing pressure difference together with increasing VOC level also indicates that it is time to replace the activated carbon filters 52.
    Because there is a check of the activity of the activated carbon filters 52, it is possible to predict the period of replacement of the activated carbon filters.
    FIG. 8 describes a sectional view of a flow channel 104. In the flow channel, a terminal 106 is provided containing a heated cable 108.
    The temperature of the cable 108 indicates the air flow. The temperature of the cable can be measured by measuring the resistance of the cable. Hereby, the system is arranged to measure the flow through the activated carbon filter.
    DK 2019 00041 U1
    FIG. 9 discloses a sectional view of a flow channel 110 comprising ultrasonic transducers 112 transmitting ultrasound 114 between the ultrasonic transducers.
    This achieves that the air flow is very efficiently measured in the flow channel 110. Several ultrasonic transducers can be used to measure more of the volume in the flow channel to obtain a better result.
