Definitions

  • This invention relates to color changers and more particularly to apparatus for selectively providing paint of various colors to paint applicator apparatus.
  • paints such as the metallics, for example, may include solids which should be maintained in uniform suspension throughout the supply and piping system during any application operation.
  • Known color changers for high pressure systems operating at ranges exceeding 1000 psi are generally referred to as dead-end, or non-circulating to gun, changers. Paint is generally conveyed to the applicator gun, moving through a system including a color changer manifold. However, when the gun or applicator is shut down, or the particular paint color is not being selected, paint flow is stopped between the changer manifold and the gun with paint circulating between the paint supply and manifold only. The paint which is dead ended between the manifold and gun can cool. Even where there are no temperature gradients, for example, solids can settle out of suspension. Thus, in a heavy or viscous metallic paint, for example, used in such known system may be subjected to both undesirable cooling and settling.
  • Prior recirculating changers for low pressure systems operating in the range of 80 to 200 psi utilized bellows devices for separating and sealing paint from elements of the paint valve actuators. Such bellows rupture and break, however, if used in a high pressure system at 1000 psi and above, for example.
  • a further objective of the invention has been to provide an improved color changer which prevents paint overheating, temperature gradients, or solids from settling out of suspension for both the paint selected and the paint of non-selected colors.
  • a color changer preferably includes a plurality of identical changer modules, one module for each color of paint to be selected, and provides for full recirculation of paint of all non-selected colors, and a continuous recirculation return to supply of excess paint of a selected color during a spraying operation in a high pressure painting system.
  • the changer preferably includes a universal applicator supply manifold and a universal applicator return manifold, defined respectively by interconnected bores in a plurality of module supply and return blocks.
  • Each module also includes a recirculation block defining a recirculation passageway.
  • a normally closed supply valve in each module, passes paint of a non-selected color to a normally closed, but pneumatically opened recirculation valve on the recirculation block. Paint is thus passed back to its supply through the recirculation passage.
  • the supply valve is pneumatically opened, the recirculation valve closed, and paint is conveyed to the supply manifold block of that module, and thus to the universal supply manifold, the spray guns, and the universal return manifold. From the return manifold, the paint flows to the return manifold block of the module and to a normally closed, but now opened, return valve.
  • the return valve is mounted to the recirculation block and passes paint to the common recirculation passage and back to the supply.
  • Each module thus preferably includes a supply manifold block, a return manifold block, a recirculation block and pneumatic piston controlled supply, recirculation and return valves connected respectively thereto, as noted, for supplying and receiving a selected paint of one color to and from universal manifolds and the supply, for recirculating paint of the one color to the supply when that color paint is not selected, and for recirculating unused paint of the one color when the one color is selected.
  • One module is nonnally provided for. each paint color, and each module is provided with bores and sealable porting so it can be easily stacked and secured by screws to an adjacent module.
  • a basic color changer according to the invention can handle, it is only necessary to add modules to the basic changer. For example, it is easy to increase the number of colors a basic two-color changer can handle merely by stacking the same number of add-on modules required for the number of colors to be added.
  • each module including and defining its own portion of the universal supply and return manifolds. No additional piping or connections, except lines to and from the additional color supply, and to and from the valve control solenoid, are required.
  • separate solvent and air modules are provided for cleaning the color changer between color changes.
  • the solvent and air modules are disposed upstream in the universal supply manifold.
  • the dump valve is disposed downstream in the universal return manifold, to provide for entire system cleaning between color changes.
  • These modules do not require recirculation valves or recirculation blocks as the used solvent is simply piped to the dump valve, and the air is also vented or piped to the dump valve.
  • the color changer of the invention can be particularly effective with high pressure airless systems.
  • the valves may be provided with additional springing to help the valve close when high pressure flow may otherwise tend to keep it open.
  • the invention thus provides a recirculating color changer wherein paint of all non-selected colors is continually recirculated, and excess paint of a selected color is also returned to supply.
  • Add-on modules define their own portions of universal supply and return manifolds, and can easil ⁇ ' be added to a basic changer to handle additional colors, while retaining the full recirculation advantages described above in a high pressure spraying system.
  • Fig. 1 a color changer 10 according to a preferred embodiment of the invention. It will be appreciated that color changer 10 is particularly adapted for utilization in painting systems which are utilized to apply more than one particular color to an object. Multiple-color painting systems are utilized in many varied applications.
  • paint of different types within an application system, such as normal paint of one or more given colors and other paints having solids therein, such as metallic paints, for example.
  • the color changer 10 is useful in a variety of varying types of painting systems where it is desired to utilize more than one color or type of paint for application by a particular applying apparatus, such as an electrostatic paint spraying gun or other form of applicator.
  • color changers are utilized in high pressure systems, that is, on the order of about 1000 psi and above, such as 2000 to 3000 psi.
  • color changer 10 includes what will be referred to as a basic two-color color changer 11 and an additional color module means 12 added to the basic two-color changer 11, so as. to form a three-color color changer 10 as shown in Fig. 1.
  • the color module 12 is shown in exploded form from the basic color changer 11 for illustrative purposes only and it will be appreciated that in use, the color module 12 is connected to and operatively associated with the basic color changer 11 to form the integral color changer 10.
  • the basic color changer 11 is provided with means for selecting between two different colors or types of paints and it will be appreciated that additional color modules, such as the module 12, can be added to make a multiple-color color changer to provide a color changer having the capacity for selecting between three or more different colors or types of paints or fluids to be handled by the system.
  • Basic color changer 11 can thus be made in a unitary construction, or can be assembled from modules such as module 12, and appropriate solvent and air purge and dump valve components.
  • the color changer 10 includes a universal paint supply manifold 13 and a universal paint return manifold 14.
  • the manifolds 13 and 14 are defined by machined aluminum blocks, such as at 15 and 16.
  • the blocks 15 and 16 are integral and extend throughout the basic two-color color changer 11. It will be appreciated that the blocks 15 and 16 could be manufactured in separate assemblies, one block for each color, as will be described with respect to the color module 12.
  • manifolds 13 and 14, respectively eventually terminate at ports 17 and 18, located in terminal blocks 19 and 20, respectively, for connection to appropriate conduits leading to and from appropriate paint spraying guns, for example.
  • Terminal blocks 19 and 20 are used at the end of changer 10 for this purpose regardless of the number of modules used in the changer.
  • this module includes a paint supply valve 25, a recirculation valve 26 and a paint return valve 27, not particularly shown in Fig. 1 but more readily seen in Figs. 2 and 3.
  • the module 12 also includes a supply manifold block 28, a return manifold block 29 and a recirculation block 30.
  • Supply valve 25 and recirculation valve 26 are connected together by means of a connecting block 31 disposed therebetween and containing a bore 32 therethrough, operatively connecting a constantly open output port 33 in valve 25 to a constantly open input port 34 in the valve 26.
  • a connecting block 36 is mounted and extends between the return manifold block 29 and the return valve 27.
  • Block 36 includes a bore 37 therethrough, interconnecting an output port 38 of the manifold block 29 with an input port 39 of the return valve 27.
  • recirculation valve 26 and return valve 27 are both operatively mounted on the recirculation block 30 which defines a common recirculation passageway 41 therein.
  • the supply manifold block 28 contains and defines a portion 13a of the universal supply manifold 13.
  • the return manifold block 29 defines a portion 14a of the universal return manifold 14.
  • the supply manifold portion 13a and the return manifold portion 14a are situated as shown in Fig. 1 to eventually be connected to the specific supply and return ports 17 and 18 of the terminal blocks 19 and 20.
  • each of the modules includes a supply manifold block 28 and a return manifold block 29, each of which defines a respective portion of the supply and return manifolds 13 and 14 in a similar fashion, as does the module 12.
  • Sealing means such as grooves and O-rings, may be provided on abutting faces of the manifold blocks to prevent leakage along manifolds 13, 14.
  • the basic two-color color changer 11 also includes equivalent structure to the module 12 for each specific color to be applied. That is, for example, the apparatus for selecting color number 1 includes a supply valve 25a, a recirculation valve 26a, and a return valve 27a (not shown), all of which correspond to the supply recirculation and return valves 25-27, respectively, of the module 12. Likewise, the apparatus for selecting paint color number 2 includes a supply valve 25b, a recirculation valve 26b and a return valve 27b, all of which also correspond for example to the supply recirculation and return valves 25-27 of the module 12.
  • each of the apparatus for color number 1 and color number 2 in separate modular form, identical to that of module 12.
  • the basic two-color color changer 11 in the form as shown in Fig. 1 as an integral unit, since the basic color changer will be utilized for operations requiring only two colors and one or more identical modules 12 added thereto when additional colors or types of paints are to be utilized in the system.
  • the basic two-color changer 11 also includes means for cleaning the entire system between changes of color or types of paint.
  • a solvent supply valve 45 (Figs. 1 and 5) is connected to the block 15 and is operatively interconnected with the universal supply manifold 13 upstream of the apparatus for applying colors numbers 1 and 2.
  • Solvent can be supplied to the inlet conduit 46 and, when the solvent valve 45 is opened, solvent is introduced into the universal supply manifold 13 where it can flow out to the guns, back through the return manifold 14 and then can be conveyed to a dump valve (Fig. 5).
  • the apparatus for introducing solvent for cleaning purposes into the system is somewhat similar to the module 12 with the exception of the lack of any type of recirculation valve, such as the recirculation valve 26 as shown in Fig. 2. Since it is not believed necessary to recirculate solvent when solvent is not being utilized in the system, the solvent valve 45 does not include an outlet port 33, which port is simply closed up, for example, where a similar type of valve is utilized. Also, it will be appreciated that any outlet port from any recirculation block, such as circulation block 30, which might be utilized with the solvent apparatus, is also closed up, except as such port leads to a.solvent and waste paint dump.
  • the solvent supply valve 45 can be opened to' admit solvent to the universal supply manifold 13. From there, solvent runs through the conduit to the spraying apparatus, back to the universal return manifold 14 and through a dump valve 48, which is a valve similar to the valve 27 shown in Fig. 2.
  • a diagrammatic illustration of the solvent apparatus is shown in Fig. 5, wherein the dump valve 48 can be opened to pass solvent and waste paint to a waste tank (not shown).
  • the solvent can thus be run through the system from upstream of all colors at an upstream portion of manifold 13, throughout the system to a dump downstream of all return manifolds 14 and return valves 26 for thorough cleaning.
  • an air supply valve is connected to a source of pressurized air pressure and is mounted on the block 15 being operatively connected also to the universal supply manifold 13 upstream of the solvent supply valve 45.
  • air supply valve 50 When air supply valve 50 is open, it serves to pass pressurized air through the universal manifolds 13, any intervening conduits, the application apparatus, the return manifolds 14, and through the dump valve or return valve 48 to the dump, thereby purging solvent from the system.
  • dump valve 48 is also opened during the air purge.
  • each module or color applying apparatus can be operated independently.
  • the valves are preferably controlled by pneumatically operated pistons which control the various valves 25-27 in each module or changer apparatus in a predetermined manner.
  • Each module is selectively operated in order to select a particular color for application by a paint applying apparatus and at the same time provide recirculation for paint of that color when such paint is not being selected.
  • valves which are utilized in the color changer 10 each constitute a valve of the type referred to by applicant as an A7A valve, which applicant has used in non-circulating dead end color changers.
  • valves 25, 26 and 27 are similar. Beginning with supply valve 25, that valve 25 is connected to. a paint supply conduit 55, connecting a. supply of paint to valve port 56.
  • the supply valve itself includes a valve seat 57 and a reciprocating valve member 58, preferably comprising a ball-like member 58 as shown.
  • Valve member 58 is mounted on a reciprocal stem 59 connected at its upper end to a pneumatically operated piston 60.
  • Stem 59 is provided above the paint inlet chamber 61 with any necessary sealing in order to maintain the paint within the valve body and to prevent it from leaking upwardly.
  • Weep holes 64 prevent any paint which does leak upwardly from entering the air system for the pneumatically operated piston 60.
  • Each of the modules may include air inlet ports, such as ports 62 (see Fig. 1), for supplying pressurized air to expansible chambers 63.
  • the respective air inlet ports 62 may be provided with appropriate air fittings for selective connection to a source of selectively controlled pressurized air, or to an exhaust.
  • air pressure in chamber 63 is exhausted back through inlet port 62 and the valve spring 65 operates to urge the stem 59 and the ball member 58 against the seat 57 to close off the passageway through the seat.
  • supply valve 25 is controlled so as to be a normally closed valve, wherein the valve is normally positioned such as shown in Fig. 3.
  • any paint admitted through the conduit 55 into chamber 61 is ducted through the bore 32 to the inlet port 34 of the recirculation valve 26, which is a normally closed valve similar to valve 25. Since valve 26 is normally closed, paint moves through that valve 26 into the recirculation block 30, only when the valve 26 is pneumatically opened. When the valve is pneumatically opened, such as when paint of the color associated with this module is not selected, paint moves through the common recirculation chamber 41 and to the paint return through a suitable conduit, such as paint return conduit 67, to the supply of paint of the particular color with which the module is associated.
  • each of the return manifold blocks 29 also includes a check valve 70, diagrammatically shown in Fig. 2 and 3, for preventing any portion of the paint between the manifold block 29 and the return valve 27 from returning into the conduit 14.
  • check valve 70 diagrammatically shown in Fig. 2 and 3
  • valve 27 when valve 27 is closed, it traps paint between the seat of valve 27 and the check valve 70.
  • This paint being non-compressible, serves to hold check valve 70 closed, and thus prevents paint of another color from passing check valve 70 toward valve 27 and paint behind check valve 70 from passing forwardly into manifold 14.
  • the paint is admitted through the supply valve 25 into the chamber 61 and through the seat 57 to the universal manifold 13, and particularly into the portion 13a of the common manifold in the manifold block 28. From there, the paint runs down to or through the manifold 13 where it exits at the terminal block 19 through port 17 and goes to the guns or paint applying apparatus, as indicated in Fig. 2.
  • outlets and inlets to and from the paint applying apparatus as shown in Figs. 2 and 3 are diagrammatic only and are shown at a 90° angle with respect to their disposition in Fig. for the purposes of clarity and to illustrate the flow of paint through the module when paint of the color which the module controls is utilized.
  • the paint is circulated to the applicators. Any paint not applied returns through the port 18 to the universal paint return manifold 14. Paint moves along the universal manifold 14 fills up such manifold 14, and opens the check valve 70 in the manifold block 29 of the module which is controlling the paint being used. Paint flows through the check valve 70, through the now opened return valve 27 and past check valve 82 into the recirculation chamber 41 and from there back to the supply of paint for the color being utilized.
  • the flow of paint through return valve 27, as shown in Fig. 2 is a flow of excess paint which is not applied by the applicator.
  • a certain amount of the paint admitted to the system through the supply valve 25 will actually be applied and will not be returned to the universal return manifold 14.
  • some of the paint will be recirculated, in the manner as shown in connection with the description of Fig. 2, back to the paint supply so that paint is not burnt within the system and so that any solids in the paint do not settle out, but remain in suspension. Should the applicators be closed off, for example, then the flow of paint through the module as shown in Fig.
  • valve 25 and the valve 27 are released and closed, while at the same the recirculation valve 26 is opened, letting the previous color of paint recirculate now only through its module.
  • the solvent supply valve 45 is opened and solvent runs through the supply manifold 13 from upstream of all color modules or apparatus for selecting a color, thereby cleaning out the universal manifold 13 and all downstream conduits and applicators.
  • the solvent is then returned to the return manifold 14 through the port 18 and terminal block 20, and runs through the return manifold 14 to a point downstream of all of the modules or color selecting apparatus to the opened dump valve 48, where the solvent is returned to a waste tank (not shown).
  • the entire system is cleaned by solvent, with paint of the various colors recirculating through each module and through the valves 25 and 26 thereof.
  • the solvent supply valve is closed and, if desired, the air valve 50 may be opened to dry the entire system by directing air' through the entire common supply manifold 13 to the applicator guns and through the return manifold 14 to the dump valve
  • the dump valve 48 is retained open while the air is blown therethrough so that air is exhausted through the dump or waste valves More typically, the newly selected color would be introduced directly after the solvent flush to push solvent remaining in the system out of the dump valve 48.
  • each of the valves 25, 26 and 27 in each of the modules contains a check valve, such as the check valve 80, 81 and 82, as shown respectively in valves 25, 26 and 27.
  • a check valve such as the check valve 80, 81 and 82, as shown respectively in valves 25, 26 and 27.
  • each of the valves is constructed and oriented such that the operative flow of paint therethrough is in the same direction as the closing motion of the ball member 58.
  • the operative flow of paint through the seat 57 is in a downward direction, which is the same direction as the ball member 58 would be used to close that valve.
  • the specific check valves 80, 81 and 82 are thus utilized to prevent any back pressure which may occur in the valves from tending to open the main ball members of the valves and thereby prevent any unintentional opening or leakage of paint beyond the valves in an opposite direction of what is intended.
  • check valves 70 and 80 are extremely important to insuring total integrity of the respective paint colors.
  • check valve 80 keeps paint of another color in manifold 13 from opening valve 25 in the non-selected module, and contaminating paint therein.
  • the closing of return valve 27 in a non-selected module traps paint of that module's color between the seat of valve 27 and check valve 70. Since this paint is non-compressible, the trapped paint is useful to hold check valve 70 closed against passage therethrough of any paint of another color, or solvent, from return manifold 14. This contamination of the paint of the non-selected modules is effectively prevented by the respective check valves 70 and 80.
  • each of the modules is easily stackable or mountable against one another to define, in part, the respective universal supply and return manifolds. This is accomplished by means of appropriate grooves and O-rings in the ports at the edge of the supply and return manifold blocks of the respective modules. It will also be appreciated that the entire changer can be mounted on a bracket, such as bracket B as shown in Figs. 2 and 5, for mounting on a framework or any appropriate supporting structure.
  • valves 25, 26 and 27, for example are connected together through appropriate stacking means such as stack screws S in manifold blocks 28 and 29.
  • valves 25 and 26 could be connected together via block 31 and appropriate, screws (not shown) extending therethrough.
  • the return manifold block 29 is connected to the return valve 27 by the block 36 and by screws (not shown).
  • the respective modules 12 can be connected to the changer 11 and to additional modules by means of stacking screws, such as the screws S as shown in Fig. 1.
  • valve 84 which is similar to the valves 25, 26 and 27.
  • Valve 84 is particularly adapted for utilization in a high pressure, airless paint spraying system, for example.
  • This valve 84 is identical to the valves 25 26 and 27 and a valve 84 is substituted for each of these in each color module for higher pressure application operations.
  • the valve 84 differs only in the addition of the helper spring 85, which is disposed above the piston 86 for supplementing the normal spring (such as spring 65 in Fig. 2) to close the valve.
  • the high pressure flow of paint through such a valve may, simply by its high pressure, tend to maintain the ball member off the valve seat, even though air pressure is removed from beneath the piston 86.
  • the spring 85 may be provided in color changers which are to be utilized with high pressure spraying systems in order to insure that the valves will close when the control air is removed therefrom.
  • each of the valves 25, 26 and 27 includes its own control air inlet port, such as port 62 which was described with respect to the paint supply valve.
  • Such inlet ports may comprise the inlet port 66 in the paint recirculation valve 26 as shown in Fig. 1, but not shown in Figs. 2 and 3 for reasons of clarity.
  • all of the return valves, such as valve 27, include air inlet ports, such as air inlet ports 68b as shown in Fig. 1, with respect to the color changer apparatus for color number 2.
  • the color changer according to the invention is capable of handling numerous different colors which can be selected by the appropriate application of control means to the respective valves of the various color modules, or the valves of the basic two-color changer 11, in order to selectively supply paint of a particular color or type and under high pressures such as 1000 psi or over to an applicator apparatus and recirculating both non-selected paints, and excess selected paint to prevent overheating, the settling of solids, etc.
  • the invention provides a modular color changer for selectively supplying paint to applicators and recirculating unselected paint constantly to the supply of paints of the non-selected. colors. It will also be appreciated that the utilization of identical color modules and their associated component portions of the universal supply and return manifolds makes the addition of numerous colors or types of paint to a basic color changer an easy task to accomplish with minimal additional piping and assembly difficulties while retaining the recirculation capacities for both selected and non-selected paints. The pressure drop across the additional color changers is maintained at a very low level due to the utilization of the respective manifold blocks, and elimination of significant additional piping.
