FIELD OF THE INVENTION

This invention relates to a process and system for marking or painting. The painting process and system is particularly useful for painting decorative designs to articles items or components used in automobiles vehicles wherein well defined edges of the painted designs are desirable and overspray is to be avoided for a good presentation.

BACKGROUND TO THE INVENTION

It is desirable In various industries, for example automobiles more specifically motorcycles, to apply decorative powder coatings or paint finishes which involve powder or paint to be applied to specific areas or surfaces of the automobile or component and which require well defined edges and/or without overspray to other regions of the component or part in question due to the aesthetic value of the painting being done. The remaining surface of the part /component may not require painting at all or require painting in different colours. In such cases as is known in prior art generally the remaining area is masked (to create, for example, a stripe), the desired location is painted and the mask is removed after the painting. However, this process involves more operations (eg masking) which results in increased processing time, cost and wastage of material (both the masking material and the excess overspray which is required to ensure a well defined edge is created once the mask is removed).

Alternatively, the desired location/portion which requires marking of a feature is applied with a decal adhesive film of required colour and the desired aesthetic effect is achieved in that way. The problem with this process is that during use and/or due to environmental conditions, the decal film may peel off or fade or otherwise deteriorate which gives a less than satisfactory appearance. Also, the application of such decals requires the use of sufficiently skilled labour with attendant costs.

Yet a further process previously used to create a desired decorative finish involves machining a groove or other feature into a surface which has already been painted. This machined groove or other feature is then coated with a clear lacquer to create the effect of a differentially painted surface with well defined edges. As the lacquer is clear, it does not need to remain strictly within the edges of the groove and therefore the entire surface, including the painted portions, is lacquered concurrently without affecting the well defined edge of the groove and the painted surface.

Other processes that could be used include adhering a decal of desired colour at the required location for the feature. Yet another process involves painting a groove formed in the article with a desired colour, masking the groove and applying a different colour paint on another part of the article.

OBJECT OF THE INVENTION

The object of the invention is to produce a surface which is a multicoloured surface.
Further object of the invention is to overcome the drawback in of the known methods which is that transition between the two colors is not sharp and clean due to scattering of the paint beyond the defined contour line or within contour line due pait edge being within the defined contour line. Very often the paint edge is never completely aligned with the contour line though it is aligned along the contour line. The object is to achieve a sharp dividing line between two colors of paint or sharp line dividing the painted portion and non-painted portion of the surface.

Further object of the invention is to provide a new method and system which achieves painting of different colors on a surface without having to hide/mask any portion of the surface.

Further object of the present invention is to provide a painting system for applying an effective amount of a paint composition or paint compositions in a pre-selected pattern on an article.

Further object of the present invention is to provide a painting system for applying an effective amount of a paint composition or paint compositions in a pre-selected pattern on a component of a vehicle or automobile.

Further another object of the present invention is to provide a process for applying an effective amount of a paint composition in a pre-selected pattern on an article and/or component.

The another object is to overcome the above defined deficiencies of prior art.

The another object of the present invention is to provide a system for applying paint to circumferential peripheral edge of circular surface article.

SUMMARY OF THE INVENTION:

The present invention relates to a process of marking or painting a feature on an article, where the article shall have some paintable surface. The invention comprises of a holder assembly(3) is arranged to attach article for painting and is adapted to move the attached article about predefined direction, and a fixed painting assembly is disposed adjacently to the surface area of the article and contains a volume of paint. Further it includes a plurality of movable paint release assembly such as paint hoses(9), paint feeding pressure pot(10), spray gun(6), nozzle which in a operation position releases paint inwardly and radially from the painting assembly towards the moving article to deposit the paint onto specific predefined portions of the moving surface area of the article by each of the plurality of paint release assembly.

DESCRIPTION OF THE INVENTION

The present invention provides a process of marking or painting a feature on an article, where the article shall have some paintable surface. The process comprising the steps of moving at least one marking device(6) relative to a surface of the article on which the feature is to be marked; and delivering marking agent to mark the feature on the article, wherein the at least one marking/spraying device(6) is positioned, by positioning means, relative to the surface of the article on which the feature is to be marked at a distance set such that the atleast marking device(6) delivers a narrow band width of marking agent to the surface of the article.

In this way, where a feature such as a stripe is being marked, a well defined edge is left between the marked stripe and the remaining surface of the article. The article may be moved rotationally or in other direction, or even multiple directions simultaneously (and along xyz axes and/or w directions) by a relative motion means, during the marking or painting operation to ensure delivery of marking agent to the correct location. This may be achieved by a different means or device to that used for positioning the marking device(s) relative to the article. It may be understood that marking device(s)(6), article or both may be moved during a marking or painting operation.

The marking device(s) may be positioned at an angle, desirably orthogonal, to the surface on which the feature is to be marked. The marking devices(6) are intended to be under supervision of a control means to ensure the required precision and definition.

The marking agent and process could involve a variety of processes including powder coating by electrostatic process or painting. Preferably, the marking device(6) is a paint head for spraying paint as is usual for automotive applications and may be a spray gun located at the set distance so that the spray gun delivers a narrow band width of paint spray.

The method of applying paint to a pre-selected pattern to the selected surface of the article comprises a following steps in sequence,

The process of painting involves mounting an article firmly in a plane by a support means. The article was then allowed to move in a predefined direction. A paint spray assembly arrangement is placed adjacent to the surface of the article to establish a path of movement of the paint. Arranging each of plurality of active spray nozzles of each of plurality paint release assembly of the paint spray assembly which is correspondingly based on the speed of movement of the article and length and width of the article, the paint is to be sprayed/released by each paint release assembly and adjusting the speed of the movement of the article mounted on the support means/sliding mechanism/positioning means. Further bringing continuously and sequentially a successive portion of the moving article in position in front of each of the paint release assembly for each selected paint release assembly to release a predefined paint onto the predefined portion selected in the length of the article for providing continuous painted surface on the predefined portion of the article. Once the surface of the article has got a continuous painted surface after which the moving article is stopped and the article is removed from the support means and all the process steps are made to stop. The paint is allowed to substantially dry on the surface to form a substantially dry paint.

The invention relates to a process or method of applying paint to an article surface in selective area as desired by the user, by applying an effective amount of a paint composition in a pre-selected pattern to the selected surface to affect a color change thereon comprising the steps described herein. The step involves mounting the article firmly in a plane by a support means adapted for moving the article in a predetermined direction during the process of painting. Then establishing a path of movement of the paint from a paint spray assembly arrangement disposed adjacent to the surface of the article. Thereafter the step is to adjusting the speed of the motion of the article or the paint spray assembly arrangement selectively. The process next involves arranging each of plurality of active spray nozzles of each of plurality paint release assembly of the paint spray assembly which is correspondingly based on the speed of motion of the selected article or the selected paint spray assembly and length and width of article or a portion of the article onto which the paint is to be released and sprayed by each paint release assembly. The process of painting means bringing continuously and sequentially a successive portion of the article in position in front of each of the paint release assembly for each paint release assembly to release a predefined paint onto the predefined portion selected along the area to be painted of the article. The paint release assembly of the paint spray assembly arrangement releases and applies the paint wherein the step of applying of the release assembly releases and sprays the predefined paint from each of the selected plurality of release assembly onto predefined portions of the area of the selected surface of the moving article assembly for determined time summing together to form a continuous painted surface on the predefined portion of the article by the selected plurality of release assembly. After the painting is over the entire process is brought to a stop and the article is removed and dried. As described above it is to be noted that the painting be controlled either by moving the article or moving the painting apparatus and managing the quantity and pattern of paint to be sprayed onto the article which is all achieved without masking any portion of the article.

The invention also provides a novel painting system for applying paint to a predefined portion of article surface to affect a color change thereon which comprises of an article supporting assembly configured to secure the article in a plane by a support means thereon for painting and being adapted to selectively move the attached article about an axis different from the mounting axis of the article and a paint spray supporting assembly configured to secure a paint spray assembly disposed adjacently to the surface of the article and being adapted to selectively move the attached paint spray assembly which paint spray assembly contains a volume of paste and further including plurality of movable paint release assembly which in a operation position releases paint inwardly and radially from the pain spray assembly towards the article to deposit the paint onto specific predefined portions of the article by each of the selected plurality of paint release assembly. The painting system allows the painting onto an article on selected portion of the article without masking the nearby area or remaining area of article and which is achieved by either moving the article or the painting mechanism and also managing the spray device.

However different techniques or applicator devices can be used to apply the paint onto the surface. Even though the preferred embodiment is described with a wheel rim which is generally circular in shape the invention is not restricted to this article. Nor the invention is restricted to any specific geometry of this article. The embodiments are for mere purpose of understanding and shall not be limiting the scope of the invention.

Where the feature to be marked or painted is a stripe, as is also common in automotive applications, each marking device, for example a paint head, or spray gun, is located at a set distance from the surface which approximates the width of the stripe like feature to be marked on the surface. In such case, a spray gun may be located at a set distance within 4 to 10 mm from the surface, more preferably within 5 to 7 mm from the surface. In contradistinction, in conventional painting, the spray gun is typically 250 mm or more from the surface. Motion means(7) may be provided to move spray gun(s) to the required locations.

Bandwidth may also be controlled by design of a nozzle of a paint head (spray gun) or marking device. Other parameters such as paint viscosity and the use of grooves(11) to confine marking agent to a particular location on the article, as described below, may be used as well.

Preferably, the viscosity of the paint, when used as a marking agent, is lower than for conventional painting and is maintained within pre-determined limits. Advantageously, the viscosity of the paint ranges from 18 to 25 seconds by Ford Cup B4, depending upon application process such as electrostatic reciprocation to conventional manual spray painting. Use of low viscosity paint ensures that a lower spray gun pressure can be used for painting resulting in less overspray and a better defined edge for the feature to be marked on the article. Advantageously, the paint is an air drying/curing paint as this will not require oven curing and will help to maximise the cost savings derived from the implementation of the invention.

Preferably, the article is provided with a groove as part of the process, said groove defining the area to which the feature is to be applied. The width of the groove corresponds to the width of the feature, such as a stripe, to be applied to the article. The width of the groove may be equal to or larger than the width of the stream of marking agent, for example, a paint spray emanating from the spray gun. The groove may be surface treated to provide enhanced adhesion of the paint to the surface of the groove relative the surrounding surface of the groove.

The groove may have a depth, at its edge, which is equal to or greater than the thickness of the paint to be applied when marking the feature. Whilst an increased depth of groove will provide advantages in terms of paint containment, other considerations such as article strength and durability impose a requirement to minimize the depth. This is especially true in the case of wheel rims. By way of example, the groove may have a depth at its edge of approximately 200 to 250 microns).

Preferably, a relative motion means of the spraying system is provided to move the article, for example by rotation or reciprocation, relative to a stationary paint head, such as a spray gun, during the marking/painting operation.

Preferably the article is feature to be marked a stripe. In such case, a marking device (spray gun) may be provided on either side of the article and the painting system then provides a paint stripe to each side of the article simultaneously, or near simultaneously, reducing cycle time and offering advantage for mass production. During the painting operation, it may assist for the article to be moved, at a fixed rate of movement, the rate of movement being selected such that a feature of the required definition is applied to the article. That is, the stripe has well defined edges and, if required, a consistent tone. It may be appreciated that the marking device(s) may be operated to mark a feature of varying tone.

Preferably, the surface on which the feature, such as a stripe, is to be marked or painted, has already been painted, in a first painting or priming step, for example to provide the surface with a background colour. For example, if the article is an alloy wheel, such painting and any necessary curing will have been conducted prior to the stage of marking a feature, such as a stripe, on the rim of the alloy wheel.
The article or component may have a surface of varying topography. In such case, the marking device may be moved to maintain the set distance between the surface of the article and marking device.

In another aspect, the present invention provides a system(1) for marking or painting a feature on an article comprising: at least one marking device for delivering marking agent, to mark the feature on a surface of the article; and a positioning means to position the at least one marking device(6) a set distance from the surface of the article such that the at least one marking device(6) delivers a narrow bandwidth of marking agent to the surface to which the feature is to be applied.

In a particularly advantageous form of the invention, a fully or partially automated marking or painting system is advantageously employed. In such a system, the marking device(s)(6), such as paint head(s) or spray gun(s), may be mounted on positioning means in the form of sliding mechanism(s) (7); and the article may be retained in a holding device during the marking or painting operation. The holding device may be capable of linear and/or rotary movement. The sliding mechanism(s) may be controlled to position the paint head at a predefined location and at a set distance from the article to which the feature is to be applied.

DESCRIPTION OF PREFERRED EMBODIMENT

The improvement proposed by this invention consists in maintaining optimum distance between the surface to be painted and the painting device and also further painting at a desired rate to a desired set of small portions of the surface through plurality of release points. An advantage of this embodiment is that only a quite narrow strips of paint has to be applied and from a optimum distance which can be done quite accurately, in particular so that a sharp edge can be obtained without using a mask.
The applicant has experimented with the process and system of the invention in an alloy wheel of a motorcycle. This is described as an embodiment herein.

In an embodiment of the invention, axis of the wheel of the vehicle or automobile is in a plane which may be horizontal or otherwise and wheel is mounted by a support/sliding mechanism and rotating the wheel with reference to an axis perpendicular to the mounting axis for starting a path of radial movement of the paint around this second axis and placing a paint spray assembly arrangement close to the circumferential surface of the wheel. Arranging each of plurality of active spray nozzles of each of plurality paint release assembly of the paint spray assembly which is correspondingly based on the speed of rotation of the wheel and circumferential length and width of wheel portion, the paint is to be sprayed/released by each paint release assembly and adjusting the speed of the rotation of the wheel mounted on the support means/sliding mechanism/positioning means. Further bringing continuously and sequentially a successive portion of the rotating wheel in position in front of each of the paint release assembly for each of the selected paint release assembly to release a predefined paint onto the predefined portion selected in the circumferential length of the wheel rim for providing continuous painted surface on the predefined portion of the wheel. Once the wheel assembly has got a continuous painted surface then the spinning wheel is stopped and the wheel is removed from the support means and the paint is allowed to substantially dry on the surface to form a substantially dry paint.

The preferred embodiment is described herein wherein a method of applying circumferential paint to a portion of wheel surface of a wheel assembly of vehicle, by applying an effective amount of a paint composition in a pre-selected pattern to the selected surface to affect a color change thereon comprises of sequence of steps. The first step is mounting the wheel in a plane by a support means adapted for rotating the wheel about an axis perpendicular to the mounting wheel axis during the process of painting. The second step is in establishing a path of radial movement of the paint around this axis and placing a paint spray assembly arrangement adjacent the circumferential surface of the wheel. The third step is in adjusting the speed of the rotation of the wheel or the paint spray assembly arrangement selectively. The fourth step is in arranging each of plurality of active spray nozzles of each of plurality paint release assembly of the paint spray assembly which is correspondingly based on the speed of rotation selected in step (3) and circumferential length and width of wheel portion onto which the paint is to be released and sprayed by each paint release assembly. The fifth step is bringing continuously and sequentially a successive portion of the rotating wheel in position in front of each of the paint release assembly for each paint release assembly to release a predefined paint onto the predefined portion selected in step (4) along the circumferential length of the wheel rim. The step six is applying paint release assembly of the paint spray assembly arrangement wherein the step of applying of the release assembly releases and sprays the predefined paint from each of the selected plurality of release assembly onto predefined portions of the circumference of the selected surface of the rotating wheel assembly summing together to form a continuous painted surface on the predefined portion of the wheel by the selected plurality of release assembly. The last step involves causing the moving wheel or the paint spray assembly to stop and inactivating the operation and removing the wheel from the support means, and thereafter allowing the paint to substantially dry on the surface of the removed wheel to form a substantially dry paint added thereto on the wheel.

The preferred embodiment is also described with the component painting apparatus for applying paint to a predefined portion of a component surface of a component of vehicle or automobile to affect a color change thereon which comprises of a component supporting assembly configured to secure the component in a plane by a supporting means thereon for painting and being adapted to selectively move the attached component about a predetermined axis and a paint spray supporting assembly configured to secure a paint spray assembly disposed adjacently to the surface of the component and being adapted to selectively move the attached paint spray assembly which paint spray assembly contains a volume of paint and further including plurality of movable paint release assembly which in a operation position releases paint inwardly and radially from the paint spray assembly towards the component to deposit the paint onto specific predetermined portions of the component by each of the selected plurality of paint release assembly. The assembly is novel for the purpose that either the component to be painted to be moved or the painting mechanism is moved and thereby having the component portion painted without a need for masking the nearby area or remaining area of component.

The system(1) may be operated in accordance with the marking or painting processes described above.

The painting system for applying an effective amount of a paint composition in a pre-selected pattern to the selected surface to affect a color change thereon which is now explained in detail with reference to the drawings as follows:

Referring now to Figures 1 and 2, illustrates the invention for preferred embodiments, there is shown a system 1 for painting a stripe on a wheel rim 2 comprising at least one marking device 6 for delivering marking agent to paint the stripe on the wheel rim 2a. The positioning means 7 is controllable to maintain a distance set such that the marking device 6 delivers a narrow bandwidth of marking agent when marking the stripe on the wheel rim 2a. That is, the narrow bandwidth minimises "overspray". Painting system 1 also includes a relative motion means 4 to provide relative motion between the at least one marking device 6 and the wheel rim 2a so that the stripe is painted around the circumference of the wheel rim 2 as required.

Painting system 1, which is mounted on a stand 8, comprises a wheel holder 3 to hold the wheel rim 2 such that the axis of the wheel rim 2 is maintained horizontal or very nearly so. The wheel holder 3 is coupled with motor drive 4, which is controlled by a motor controller (not shown), to control the rotational speed of the wheel rim 2 during the stripe painting process. The motor drive 4 rotates the wheel rim 2 during a stripe painting operation at a fixed speed of rotation, for example 15 rpm, this speed being selected to ensure a stripe of the required definition is painted on the wheel rim 2 . The painting spray guns are placed on either side of wheel rim 2 at the lower side of the wheel rim 2 to enable painting of stripe on both sides.

The spray guns 6 are movable by positioning means in the form of suitable sliding mechanisms 7 allowing adjustment of the distance between the spray guns 6 and the wheel rim 2 . The sliding mechanisms 7 also allow the spray guns 6 to move out laterally to facilitate removal of the wheel rim 2 from the wheel rim holder 3. The paint hoses 9 connected to paint feeding pressure pot 10 supply paint to the respective spray guns 6. Different pots may be provided for different colours. The paint has suitable viscosity (for example 18 to 25 second as measured by Ford Cup B4) and quick drying nature avoiding the need for oven curing. The curing may be in the oven without suffering any specific disadvantages due to this type of curing. The painting system includes a control panel 5 which actuates clamping/unclamping of wheel rim 2 , driving/stoppage of drive motor 4, sliding movement of spray guns 6 and other operations of painting system 1.

The pre-treated/painted wheel rim 2 may be manually mounted on wheel holder 3 and clamped into position with a suitable clamping mechanism. With the actuation of switches on control panel 5, the spray guns 6 are positioned in front of the surface of wheel rim 2 which is to be painted with a stripe. The surface of wheel rim 2 to be painted may be provided with a groove 11 (as seen in detail in Fig 2a) with predefined width, depth and corner radii to facilitate the painting operation while
minimising overspraying and providing a well defined edge to the stripe on the wheel rim 2a.

Once the start command is actuated for the painting process through control panel 5 the wheel rim 2 starts rotating, the spray guns 6 are brought to a predefined position at a set distance from the wheel rim 2 by the control panel 5. The spray guns 6 are relatively moved by sliding mechanisms 7 to the set distance from the wheel rim 2 so as to avoid spraying of paint outside the bandwidth to be painted (overspraying). The painting process is carried out for preset duration.

The set or predetermined distance between spray guns 6 and alloy wheel rim 2 for the particular preferred embodiment described here is maintained in a range of 5 to 7 mm. The spray guns 6 are selected to avoid overspray and consistent painting bandwidth as required. The particular painting bandwidth for the illustrated embodiment is 6 mm, this bandwidth being substantially equal to groove width 11 of wheel which is to be painted.

After the cycle is over, then paint flow stops, the rotation of wheel rim 2 is stopped and spray guns 6 are retracted to home position away from the wheel rim 2. The wheel rim 2 is unloaded manually and the paint is allowed to cure at room temperature or oven curing in the oven if desired. After that, the wheel rim 2 may be directed to further assembly operations including affixing of the tyres and so on. The above painting cycle is then repeated for the next alloy wheel. It may be appreciated that the production rate is rapid.

With this method a very narrow transition zone between the two colors is achievable that may not be visible to the naked eye.

With this method a very narrow transition zone between painted portion and non-painted zone is achievable that may not be visible to the naked eye.

Parameters such as speed of rotation of the wheel rim 2, paint viscosity, set distance between spray gun and object to be painted, and bandwidth of spray gun may vary and can be determined on the basis of the nature of the article.

Figure 3 illustrates the sequence of steps in the above described painting operation. In particular, Figure 3 shows progression of alloy wheels from machine shop to pre-treatment, painting and curing. Then the stripes are painted on wheel rims of the wheels as above described, with or without oven curing being required, and the wheels are passed on to further wheel assembly operations.

Whilst the specific definition of what may constitute a "well defined edge" may be different from manufacturer to manufacturer, it is to be understood that the invention is intended to provide a process which provides a painted edge which is comparable for the purpose of aesthetics to that achieved using a masking technique or by the use of decals, even though perhaps microscopically the edge definition achieved using the different process may in fact be differentiated.

Modifications and variations to the process and system for marking or painting a feature on an article as disclosed in this specification will be apparent to the skilled reader of this disclosure. Such modifications and variations for eg., moving spray assembly and fixed component or article, type of movement of component or spray assembly (i.e. linear, circular etc.) and other variations are deemed within the scope of the present invention.
