Definitions

  • the present invention relates to an extraction system for containing and removing vapours generated during application of films to a surface and, in particular, but not exclusively to the safe removal of spray mists, particulates and vapours generated during body repair and/or repainting of a vehicle.
  • a vehicle requiring body repair and/or repainting is subject to a number of different processes depending on the type of repair or repaint.
  • the repainting process comprises a number of distinct stages including for example preparation for the paint, typically involving sanding the original surface to provide adhesion for the extra paint layers to be applied, or the removal of the paint film to provide adhesion for the layers of shaping filler that are to be applied to a dent and/or blemish in the surface.
  • Polyester filler is normally used to reshape damaged areas to the pre-damaged state. After shaping, final surface preparation requires the application of a hi-build primer to enable final levelling and filling of very small imperfections.
  • the hi-build primer or paint is usually applied using a spray gun or aerosol with a material transfer efficiency of between 50 to 80%.
  • the spray gun or aerosol atomizes the paint or primer into a fine spray by using either compressed air or a propellant.
  • the nature of this spray requires that undamaged surfaces adjacent the area to be repaired or repainted must be masked-off, that is covered, to prevent migration of the spray onto such.
  • the masked-off areas not only include adjacent surfaces of the vehicle, but often also adjacent vehicles and surfaces of the workshop, this is because if spray or overspray contacted clean or undamaged surfaces this would give rise to time consuming and costly removal thereof.
  • a dedicated spraybooth is provided within the workshop which provides an enclosed environment and all or part of the spraying process is carried out inside the controlled environment of the spraybooth.
  • the spraybooth is usually equipped with an extraction system which draws the air containing the noxious vapours from the booth and then filters out hazardous chemicals therein before release of the cleaned extracted air into the atmosphere.
  • the hi-build primer After the hi-build primer has been applied then it must be sanded to allow for any imperfections to be removed. Since the dedicated controlled environment is a critical resource within the workshop the vehicle or vehicle part is removed therefrom for this sanding operation. Once the sanding operations is complete the vehicle or part is re-masked and re-entered into the controlled environment for the further or final top coat of paint.
  • the dedicated controlled environment such as a spraybooth as mentioned above is a critical resource and the efficient and cost effective use thereof is essential to ensure profitability of the workshop.
  • the continuous removal and re-entry of the vehicle or part thereof, whilst done to free the spraybooth for spraying and/or curing operations nevertheless leads to downtime reducing effective use of this facility.
  • a controlled environment requires a large building to house it and it is an expensive item to purchase, meaning that it is often not possible for local small workshops and garages to offer a paint and repair service. This is not only an inconvenience to the customers who must then take their vehicle to a remote dedicated bodyshop facility, but is also a loss of custom for the local workshop.
  • an extraction system comprising a containment unit with means to enclose a selected area on a surface of an object to the sprayed and/or dried, the unit having an outlet which is connectable to an extraction unit and an inlet connectable to an air source.
  • the extraction system may comprise at least one flexible duct connectable between an inlet of an extraction unit and the outlet of the containment unit. This has the advantage that the duct enables movement between the extraction unit and the containment unit , enabling the containment unit to be selectively located at a position remote from the extraction unit.
  • the extraction system may include a moveable mounting for the duct. This will enable further flexibility in the placement of the containment unit.
  • the extraction system may comprise an extraction unit which may comprise at least one of an inlet, an extraction pump adapted to draw fluid into the extraction unit through the inlet, a filter adapted to remove particulate and hazardous contaminates from the fluid, and an exhaust to expel cleaned fluid into the atmosphere.
  • the extraction unit may additionally include a removable container to collect said removed contaminates and particulates.
  • the extraction unit may be mobile. This enables the extraction system to be used outside the confines of a workshop.
  • the containment unit may include at least one deflector.
  • the containment unit inlet may form an opening to the containment unit and may enable direction of a spray from a spray gun and/or aerosol into the containment unit.
  • the deflector may be provided about the inlet.
  • the deflector may include a movable shield, which may be located at least partially over the containment unit inlet any may be located adjacent said containment unit outlet.
  • the containment means may include a frame and the enclosing means may be a flexible media.
  • the flexible media may comprise means to enable its attachment to at least one of the surface of the object to be sprayed and/or painted or the frame. The flexible nature of the media enables the containment means to be readily adapted to enclose a variety of different sized surface areas.
  • the flexible media may be replaceable and may be in the form of flexible sheeting, the attachment means may be in the form of adhesive tape.
  • the extraction system may comprise a curing unit.
  • the curing unit may comprise a light source to effect curing of a painted surface.
  • the light source may be an ultraviolet light source and/or infrared light source.
  • the curing unit may be adapted to fit into said containment unit inlet.
  • the curing unit may have means to seal the inlet to contain the light from the source within the enclosure. This has the advantage that light from the light source does not leave the containment unit preventing damage by fugitive rays to operators' and bystanders' eyes. Furthermore the curing operation may give rise to hazardous gas which can be readily extracted via the extraction unit.
  • the curing unit may have cooling vents to enable air to enter the containment unit, this enables replacement of air extracted. The cooling vents may be shielded to prevent leakage of light from the unit.
  • the extraction system may comprise a forced air supply which may be heated.
  • the forced air supply may be provided on an articulated arm to enable its accurate placement.
  • a method of fluid extraction comprising the steps of enclosing a section of a surface to be sprayed and/or cured and/or dried within a containment unit and extracting fluid from the containment unit using an extraction unit.
  • the method includes the step of spraying within the containment unit the said surface with a paint and/or primer whilst at the same time extracting fluid from the containment unit
  • the method includes the step of drying or curing a painted surface within the containment unit at the same time as extracting said fluid.
  • the method may comprise the step of filtering said extracted fluid to remove particulate and/or contaminates.
  • the method may include the step of deflecting said spray within the containment unit.
  • the method may include the step of heating air within the containment unit prior to spraying. This has the advantage of creating a warm air environment prior to application of paint materials. Compliant coatings, waterboume base coat and ultra high solid top coats cannot be effectively applied if the temperature is below 15 0 C. This enables repairs to be carried out in unheated buildings and outdoors when the temperature is low, by creating an idea environment for the application of a particular material.

  • the hood 6 is adapted to contain a selected area to be resprayed and in use paint is sprayed into the hood 6 on to the selected area, whilst the extraction unit 4 sucks air from the hood 6 via the duct 8.
  • the interior of the hood 6 is designed to provide an aerodynamic foil which retains over-spray for extraction with the air from the hood 6.
  • the system comprises a filter for removing hazardous gases and particulates from the extracted air, before the cleaned air is then released into the atmosphere via exhaust flue 12 of the extraction unit 4.
  • the hood 6 is mounted on a substantially H-shaped, wheeled stand 12.
  • the stand 12 has a mast 14 extending substantially vertically thereof which is provided with a longitudinally extending glide section 16 in which is slidably retained a hood support bracket 18.

  • the hood guide bracket 22 is in the form of a grip type retaining ring and the other end of the mounting tube 24 is slidably retained therein.
  • the hood guide bracket 22 is provided with a swivel adjustment handle 26 which is operable to lock the position of the mounting tube 24 and thereby that of the hood 6, and a position whereby the mounting tube 24 is movable and thereby therewith the hood 6 in a transverse plane relative to the vertical plane of the mast 14, and in which the mounting tube 24 and thereby the hood 6 can also be rotated relative to its mounting in the guide bracket 22.
  • the above described possible adjustments to the hood 6 enable a full range of movement of the hood 6 enabling its accurate positioning over a surface to be resprayed or dried.
  • the H-shaped stand 12 comprises two spaced apart parallel bars 12a,
  • the parallel bars 12a, 12b are provided with swizel castors 28, which enable the stand 12, 14 to be manoeuvred to a selected location such as a vehicle, a panel of which requires respray. The orientation of the hood 6 is then adjusted in order for the hood 6 to contain the panel or area requiring respray (which will be described further hereinunder).
  • Each end of the parallel bars is provided with a moulded rubber bumper 30 which prevents damage to the wheels of the vehicle, in the instance that the stand is accidentally manoeuvred into the tyre.
  • the height of the stand 12 is such that the parallel bars 12a, 12b can be manoeuvred, at least partially under the chassis of the vehicle, enabling the hood 6 to be placed for example on a top surface of the vehicle, such as the hood or roof.
  • the parallel bars 12a, 12b are spaced apart at a distance which enable them to straddle the width of the wheel.
  • the mast 14 additionally carries a spray gun connection pipe 32 extending from a filter regulator 34.
  • the filter regulation 34 has for example a maximum pressure setting of 1.5 bar to ensure correct air pressure for atomisation of paint materials within the hood. In use a spray gun is attached to the free end of the spray gun connection pipe 32.
  • the hood 6 is a heavy duty plastics moulded design edged with a soft rubber strip to protect vehicles during use.
  • the hood 6 has a substantially rectangular outer frame 36 surrounding a through opening 38, the said hood opening 38 providing access into the containment zone created by the hood 6 for a spray gun.
  • the hood 6 is provided with an outlet 40, which is connectable to the flexible ducting 8.
  • the outlet 40 is connected to the hood opening 38 via an internal cavity 4 (as best illustrated in Fig. 7) provided in one of the walls of the outer frame 36.

  • the extraction unit 4 is additionally provided with a low airflow indicator and an alarm.
  • the low airflow indicator monitors the suction of the extraction unit 4 and if it drops below a preset value, which would indicate that one or more of the filters are blinded and thereby require changing, the low airflow indicator is adapted to trigger the alarm to provide a visual and/or audible signal that the filter(s) needs changing.
  • the extraction system 2 is operated as follows: As best illustrated in Figs. 3 to 6 the areas of the item around the area to be repainted are masked using a plastics or paper media 48. The edges of the media 48 are attached around the area to be repainted 50 using masking tape 52. The hood 6 is then moved over the area 50 to be painted and the free edges 54 of the media 48 remote from the area 50 to be painted are then pulled fully round the exterior of the hood 6 and attached thereto using a resilient masking band 56 provided about the outer frame 36 of the hood 6. This opening 38 in the frame 36 thereby provides an enclosure 39 about the area to be repainted 50 which is sealed to the vehicles surface.
  • Access to the area to be repainted is provided through the opening 38 in the hood 6.
  • the spray nozzle 58 is placed through the opening 38 into the enclosure 39 of the frame 36 and the extraction unit 4 is switched on thereby drawing air out of the enclosure 39 via ducting 8.
  • the spray nozzle 58 is applied via the spray nozzle 58 to the surface to be painted 50.
  • Fresh air 66 is drawn in through the opening 38 from the atmosphere due to the partial vacuum created in the enclosures 39. Excess material/gases forced to the bottom edge of the enclosure 39 is extracted through the primary filter 42 into the internal cavity 41.
  • any excess material 62 which is deflected upwards from the corners is unable to leave the enclosure 39 via the opening 38 because the frame 36 acts as a spoiler and contact with the interior of the frame 36 causes the material 66 to lose inertia and to be deflected back down into the enclosure 39 via entrainment in the flow of incoming fresh air 66 towards the entrance 42 to the internal cavity 41.
  • the frame 36 is provided with overhanging shoulders 68 which extend inwardly across the hoods opening 38, these shoulders 68 provide additional deflection surfaces, to increase containment.
  • One of the shoulders 68a located adjacent the point of extraction 42 provides a larger defection surface in this region.
  • a curing unit 70 then can be fitted to the enclosure 39.
  • a curing unit mounting bracket 72 is provided on the mounting tube 24, which bracket 72 provides a pivotal stand for the curing unit 70°.
  • the curing unit 70 is then adapted to seal the enclosure 39 by pivoting it to fit into the opening 38 of the frame 36 to provide a completely sealed unit for a curing operation.
  • the curing unit 70 can comprise a light source 76 such as an infrared or ultra violet light source to cure the paint.
  • the curing unit 70 has a power supply and a control unit which is used to program the curing cycle.
  • the curing unit is provided with a microswitch which only allows operation of the curing unit when it is fully within the opening so as to provide a light seal.
  • the curing unit 70 is also provided with cooling vents 78 enabling air to be drawn in to the enclosure 39.
  • the cooling vents 78 are provided with a light seal.
  • the extraction unit 4 is operated to draw air from the enclosure 39, thus removing and containing any gases created during curing.
  • the system 2 comprises a heating unit which comprises an articulated arm 80 mounted at one end to the mast 14.
  • the other end of the arm 80 carries an air blowing system 82 having an outlet nozzle 84, the air blowing system comprises a heater for warming the air.
  • the articulated arm 80 is foldable to hold the air blowing system 82 remote from the opening 38 to the hood 6, or can be deployed to insert the outlet nozzle 84 of the air blowing system through the opening 38 at a desired location, or to direct an air stream from the blowing system into the hood 6.
  • the air blowing system 80 is particular useful for drying water based paints in colder climates by providing additional turbulence and heat about the surface of the area to be dried and creating correct temperature for drying; water based paints generally require temperatures in the region of 15 to 40 0 C to dry.
  • the air blowing system 80 can be directed to provide an air jet obliquely towards the surface to be dried and thereby obliquely to the inflow of air through the opening into the hood created by the operation of the extraction unit 4, by this means the air from the air blowing system 80 disrupts the inflowing downdraft of air into the enclosure 39 of the hood 6 causing turbulence therein, with the formation of air vortices along the painted surfaces which accelerates drying thereof.
  • the extraction of air during the drying process by the extraction unit 4 also extracts vapours and particulates from the drying paint for safe containment, whilst the deflection of the hoods internal surfaces 44 contain such within the hood for extraction.
  • the hood 6 can be of any shape and/or size and that the deflection shoulders could be omitted, or the deflection surfaces could be adjustable. Also a variety of different hoods could be provided with each extraction unit 4, by this means a suitably sized and shaped hood can be selected for the area requiring repainting. Alternatively the hood can have adjustable sides. Likewise the curing unit could be adapted to provide a fit to a variety of hoods. A plurality of curing units could be provided each having a different curing system, such that a means of curing most suitable to the type of paint to be cured can be selected. Alternatively a plurality of different curing means may be provided within a single unit.
  • the curing unit has been described as fitting into the opening, other arrangements could be envisaged, for example the curing unit could be fixed in the containment unit. Whilst a manual adjustment of the position of the hood as been described, the stand and mast could be provided with pneumatic means to power the adjustment of the orientation of the head.
  • a fixed extraction unit has been described, other forms of extraction unit could be used for example a mobile extraction unit on wheels.
  • the extraction unit could be provided with a containment unit to collect the extracted contaminants for safe disposal.
  • the duct is mounted on a rail 200 via a trolley moveable 202 along the rail.
  • the rail 200 can be fitted at a low level close to the floor of a workshop, or to a ceiling of a working shop.
  • the duct 8 and hood 6 can then be moved around the workshop to an area where it is required.

Abstract

Système d'extraction localisé (2) permettant l'exécution d'un processus de finition à la peinture sans nécessiter de cabine de peinture classique. Le système (2) comporte un cadre (36) et des moyens de le fixer autour d'une portion de surface nécessitant une pulvérisation, un durcissement et/ou un séchage, le cadre (36) formant une enceinte de confinement localisée autour de ladite surface, le cadre (36) possédant un moyen d'extraction qui aspire l'air depuis l'ouverture centrale (38) du cadre et aspire en même temps tout excédent de pulvérisation de peinture par ladite ouverture (38) pour l'éliminer en toute sécurité. Le cadre (36) comporte éventuellement des moyens de déflexion pour piéger l'excédent de pulvérisation dans les limites du cadre (36) et en option une unité de durcissement qui s'adapte dans l'ouverture du cadre en vue de durcir la surface peinte, le moyen d'extraction étant en fonctionnement au même moment afin d'aspirer les vapeurs de peinture émises durant le séchage. Le système d'extraction peut en outre comporter une unité de séchage dotée de moyens pour fournir un courant d'air forcé dans le cadre en vue de faciliter le séchage.
