Background technology
Spray applicators is used to apply various types of coating on object in process.Usually use robot device to apply car body with spray applicators.Robot can be programmed, and carrying out a series of operation, and is adjusted to the paint waste of minimum and makes that with program fast the car body part suitably and is exactly covered.
The atomizing applicator is used to reduce quantity for spray and further cuts the waste.In known atomizing applicator, cup is with rotation at a high speed, and coating, for example paints, and is arranged on the inboard of cup.Because centrifugal force outwards moves and shifts out when glass surperficial, coating is atomized into fine mist and is directed to object to be coated when paint or other coating.Known employing electromotive force make the charged and land of the mist of atomizing on object to be coated so that coating is adsorbed on the object, further reduced spraying, improve the covering on erose target object and make waste minimum.
The air-flow that known use is directed from applicator is to limit towards object and guiding coating.The hole of various diameters and length and passage are used to provide the atomizing spraying of required spray pattern shape.The hole can be the part of the shaping air branch road of the part of air nozzle of spray gun or rotary atomizer.Because the shaping air hole has the minor diameter of certain-length,, may change like this that air flows and the required function of shaping air so hole and passage may be stopped up by dirt or paint.Detect the hole to get rid of manually lancing door of fragment by using little digging tool.But manually cleaning may be damaged edge and diameter surface, causes that fault or unwanted shaping air flow.In addition, be slow by detecting manual cleaning, need to apply operation and stop the long period.
The inside and outside cleaned at regular intervals that all needs of cup.In some production process, for example for car body, the known parts that will allow are along the sequential advancement of production line with random color.Therefore for each object to be coated, it may need to change from the painting color that previous object uses the color of coating.Therefore, some surface at least of applicator must be cleaned when changing coating.
Though the outer surface of cup does not directly contact coating to be used, outer surface may be polluted by coating from the mist in being present between spraying.If remaining coating is allowed to accumulate on the bell cup surface outside, if be removed, the coating that then remaining coating may contaminate subsequent, and may change the operation of applicator unfriendly, this comprises the shaping air-flow of obstruction along the outward flange guiding of cup.Knownly provide a kind of clean hatch, and in specific interval, applicator moved to the rear portion that described clean hatch cleans cup.Moving to special-purpose cleaning position may lose time, and cleaning may be wasted cleaning fluid on clean hatch.
Need to make that the required time that is used to clean is minimum.The parts that move along production line can be by only there being several seconds the time interval to separate, and need be in normal aperture time cleaning and prepare applicator so that clean operation can not be slower than the general speed of assembly line significantly.The cleaning agent of required use may be expensive for some coating.Therefore, need to make that the amount of the cleaning agent that be used to clean use is minimum.Reduce to be used to clean the required time and to reduce required cleaning dosage and can reduce cost and increase the productivity ratio that applies operation significantly.But very difficult realization has makes the cleaning of coating drying quickly.

More specifically with reference to Fig. 3, rotation cup 18 is arranged on the end 30 of air turbine 32 now.Turbine 32 with rotation at a high speed, thereby makes cup 18 rotate by end 30 with high speed by the forced air operation.Paint supply pipe 34 passes turbine 32 and extends, and has outlet 36 on cup 18, is fed in the cup 18 and in cup from for example coating of paint of supply (not shown) thus to be discharged.Divide part, sputtering plates or other suitable one or more members 38 and device can be arranged in the cup 18, in the face of supply pipe outlet 36 or related, perhaps can be arranged to receive coating and cup 18, distribute coating equably from supply pipe 34 with it.The common structure and the operation of applicator 10, comprise the structure and the operation of turbine 32, supply pipe 34, and coating on cup 18 deposition and to handle be known for a person skilled in the art, and further do not specify in this article.
In the cup shown in the exemplary embodiment 18 is around its rotatable cup or bowl bodies.Cup 18 has inner surface 40 and outer surface 42.The cup-like shape of typical cup 18 is provided with narrower cardinal extremity 44 and the front end 46 of the broad that stops at leading edge 48 places; But, should be appreciated that the cup of other shape, for example the cup of substantially cylindrical shape also can advantageously be used in combination with the present invention.Inner surface 40 is smooth substantially, and outwards expands to leading edge 48 from cardinal extremity 44.Outer surface 42 also is smooth, and outwards expands from cardinal extremity 44.
It is pressurized air sources that air supplies with 80, and it can be the same pressurized air source that is used for operating air turbine 32, and/or can be to be used for being shaped the same pressurized air source of the air that is fed to nozzle 60,62.Alternatively, air supply 80 can be different pressurized air source.Air supply with 80 by air supply valve 102 fluid flow communications in pipeline 100 and the inner shaping air valve group 86 be connected to inwardly projecting orifice 60.Air supply 80 by air supply valve 106 fluid flow communications in pipeline 104 and the outside shaping air valve group 88 be connected to outer fluid nozzles 62.And, air supply with 80 by air supply valve 108 fluid flow communications in the paint supply valve group 90 be connected to coating supply pipe 34.In addition, air supply 80 is communicatively connected to cleaning nozzle 94 by the air supply valve 112 in the cleaning nozzle valve group 92 by pipeline 110 fluids.
It is the source of solvent that are applicable to the coating that is applied by applicator 10 that solution supplies with 82, dilutes and eliminating coating with the surface that the coating from applicator 10 contacts.Solution supply with 82 by solution supply valve 120 fluid flow communications in pipeline 100 and the inner shaping air valve group 86 be connected to internal flow nozzle 60.Solution supplies with 82 by pipeline 104 with externally be connected to outer fluid nozzles 62 solution supply valve 122 fluid flow communications in the shaping air valve group 88.And, solution supply with 82 by solution supply valve 124 fluid flow communications in the paint supply valve group 90 be connected to paint supply pipe 34.In addition, solution is supplied with 82 and is communicatively connected to washer jet 94 by the solvent valve 126 in the washer jet valve group 92 by pipeline 110 fluids.
Air supply valve 102,106,108 and 112 and solution supply valve 120,122,124 and 126 controls be clipped to the air of inwardly projecting orifice 60, external nozzles 62, pipe outlet 36 and washer jet 94 and flowing of solution from its source of supply branch.Each valve can be independent of other valve by the operation signal that comes self-controller 84 and be opened or cut out, so that fluid, air or solution can flow to the nozzle 60,62,94 in downstream and export 36 or stop it to flow respectively from its source of supply.Controller 84 can be based on the analog or the digitial controller of logic, or simple electric control, is used for opening and closing alternatively air supply valve 102,106,108 and 112, and solution supply valve 120,122,124 and 126.Therefore, controller 84 is connected to valve 102,106,108 and 112 by holding wire 130,132,134,136,138,140,142 and 144 respectively, and solution supply valve 120,122,124 and 126.Those skilled in the art will readily understand, slave controller 84 is to air supply valve 102,106,108 and 112, and the signals of solution supply valve 120,122,124 and 126 transmission can be the signal of telecommunication, with the fluid signal or the similar signal of pneumatic, waterpower or other pressure signal form, and holding wire 130,132,134,136,138,140,142 and 144 can be wire holding wire, the waterpower line (hydraulic lines) of electric wire or other carrying signal or the class liny that is suitable for transmitting signal.Also can use from being connected to emitter on the controller 84 to the radio communication of the receiver related with valve.
In applying the process of coating, cup 18 is rotated with high speed in a known way by the operation of turbine 32.Coating, for example paint is fed into the inside of cup 18 from its source of supply (not shown) by supply pipe 34, and is deposited on the inner surface 40.The centrifugal force that acts on the coating makes coating move towards leading edge 48 along inner surface 40.Leave leading edge 48 along with coating advances to, coating is quickened forward and outwards with respect to cup 18.
Operation shaping air system 20 with the jet mode of restriction from the coating of leading edge 48 ejections, and improves the transfer efficiency that is applied to the coating on the object to be coated thus.Those skilled in the art will appreciate that respectively by pipeline 100 and 104 and provide forced air for inwardly projecting orifice 60 and external nozzles 62.Comprise from the fluid stream 64 of the air of inwardly projecting orifice 60 near and be attached on the outer surface 42, flow towards leading edge 48 along outer surface 42.When coating left leading edge 48, inner fluid streams 64 directly acted on facing to coating thus.Directly limit and the control jet mode.Air stream 64 has formed barrier, or stops the further outwards expansion of jet mode in cup 18 fronts.Forced air also offers external nozzles 62, and comprise the control of strengthening from internal air stream 64 towards the external fluid stream 66 of the air of front end 46 guiding of cup 18 from nozzle 62, with control, restriction and shaping coating pattern towards movement of objects to be coated.
As required, clean according to the present invention.Can periodically clean,, perhaps,, then clean, pollute coating material with the residue coating before preventing if change coating so that stop up minimumly.In order to carry out clean operation, stop being fed to the supply of the coating of supply pipe 34.Air and solution from air supply 80 and solution supply 82 provides the purpose that is used to clean by valve group 86,88,90 and 92 respectively.Should be appreciated that cleaning course to be illustrated can simultaneously or carry out continuously, and if desired, the cleaning of outer surface 42 is less often carried out than the cleaning of inner surface 40.
For cleaning inner surface 40, by the control operation valve 108 and 124 of controller 84, with air and the solution that mutual discharge is provided.Air and solution do not mix, but are arranged to going out or pulse (bursts or pulses) in succession.Carry out the dilution of film coating by solution, and the material of dilution is impacted by subsequently air and is forced to leave.Extra air discharged and solution can then carry out required cleaning.The air of the pulsation in this mode and solution are called " air/solvent chop " herein, can cause vibration in supply pipe 34.The coating that these vibrations that are commonly called " hammering " are used to get rid of hardening or thickening accumulation carries out scrubbing action consumingly thus, with the passage of cleaning by supply pipe 34, and the surface and the inner surface 40 that divide part 38.
Similarly, the air supply valve 102 and the solution supply valve 120 of inner shaping air valve group 86 are pulsed in the air/solvent chop mode by the control signal of controller 84, provide air and the solution of going out alternately or pulsing for inner shaping nozzle 60 to pass pipeline 100.The inner shaping nozzle 60 of the air of going out alternately and solvent clean, coating may be accumulated in around the inner shaping nozzle or in the inner shaping nozzle, and hinder the air that is used to be shaped and flow.The hammer effect of air/solvent chop has been got rid of the coating that may be accumulated in the nozzle 60.In addition, the air of shaping nozzle 60 discharges internally and solution are attached on the outer surface 42 and along outer surface 42 and advance, and are used to clean the coating that may deposit thereon.
The air and the solution that are fed to inwardly projecting orifice 60 and external nozzles 62 make nozzle stay open with unimpeded, thereby emit the shaping air of required mode in the process that applies.By keeping fluid tip 60,62 and leading edge 48 cleanings and not having accumulation can keep required coating pattern control.Adopt effective cleaning of air/solvent chop only to need the minimum time.If outer surface 42 needs further cleaning, can spray 96 by air and the solution that pipeline 110 is emitted additional quantity from the cleaning nozzle 94 of special use.Valve 112 and 126 can be opened and closed under the control of controller 84, with air and the solution that provides continuous interactive to go out in air/solvent chop.In a kind of preferable configuration, cleaning nozzle 94 is positioned near the cardinal extremity 44, and provides fan-shaped to spray on outer surface 42.But should be appreciated that, not only nozzle can be set, and can locate one or more nozzle that with other position on outer surface 42, for example the position of close front end 46 provides air and solution.In addition, can use other discharge mode from this cleaning nozzle.Shown particular arrangement only is a typical case.
The cycle of air and solution supply can change in an air/solvent chop cycle process, and this change can be the quantity of the circulation used in cleaning course, to obtain optimum cleaning.Can expect that " air effect " part of circulation is shorter than " solution effects " duration partly of this circulation usually, but this cyclic part also can have the equal duration or have long " air effect " cyclic part.For example, for some paint, think that " solution effects " part of a circulation can continue about 1.7 seconds, and " air effect " of this circulation part can continue about 0.4 second; And can use 3 or 4 circulations.Also consider, in some cases, can use the overlapping of the air of this circulation and solution part; But the major part of this circulation only is air or solution in the air/solvent chop clean cycle.By making valve group 86,88,90 and 92 be positioned adjacent to applicator, can optimize the hammer effect of air/solvent chop cycle, thereby before arriving passage to be cleaned or hole, can not suppress this effect significantly.Preferably the valve group is attached in the applicator, to improve scrubbing action.
Should be appreciated that the single circulation in air/solvent chop can be gone out air and be begun, to force coating to pass opening or to leave the surface, perhaps, this circulation can be gone out the solution that is used for dilution rapidly and cleans and be begun, and it is following the air stream that is used to purify.Can operate as the fluid control systems 12 of the parts of cleaning course to managing 34, dividing the soft cleaning of part 38, inner surface 40 and outer surface 42 that the mixture of air and solution is provided.
Aforesaid distortion and improvement fall within the scope of the invention.Being appreciated that herein that the present invention open and that limit may extend into mentions from this paper and/or accompanying drawing or all various combinations of conspicuous two or more independent features.The aspect that has constituted various variations of the present invention that all these are different.Embodiment described herein has illustrated and has been used to realize known best way of the present invention, and can make others skilled in the art can realize the present invention.Claim should be interpreted into the various embodiments in the scope that is included in the prior art permission.
Various feature of the present invention is illustrated in the following claims.
