Definitions
- the present invention relates generally to spray gun type liquid spray devices, and more particularly, to an automatic spray gun manifold having a modular construction.
- Modular spray gun manifold assemblies that include a plurality of laterally spaced spray guns supported in a row for discharging an elongated spray pattern are known. Such manifolds are used, for example, in pill coating machines in the pharmaceutical industry. In these applications, the manifold must be movable between a predetermined operative position relative to a rotatable pill tumbler for applying the coating and a position in which the manifold is arranged away from the tumbler to facilitate cleaning. [0003] Current manifold designs require a support structure to hold the spray guns in place.
- manifold supports make it difficult to mount the manifold in cantilever fashion, such as from a pivot door of a pill coating machine and to manipulate the manifold as may be required during use and/or cleaning.
- current manifolds typically require a multiplicity of fluid supply lines that run along the support structure and communicate with each spray nozzle. This type of manifold not only requires extensive plumbing, but it is also difficult to clean, particularly to the extent required for use in pharmaceutical and food applications.
- an object of the present invention is to provide an improved lightweight spray gun manifold adapted for easier mounting and manipulation.
- Another object is to provide a modular spray gun manifold as characterized above which eliminates the necessity for massive support members that significantly increase the weight of the manifold and impede easy movement of the manifold.
- a further object is to provide a modular spray gun manifold of the above kind in which fluid directing conduits constitute the support structure of the manifold.
- Still another object is to provide a modular spray gun manifold of the foregoing type that is adapted for easy disassembly for cleaning, or for enabling a change in the number of spray guns in the manifold.
- FIG. 1 is a perspective view of an exemplary modular spray gun manifold in accordance with the invention.
- FIG. 2 is an enlarged, partially exploded perspective view of the modular spray gun manifold of FIG. 1 showing one of the spray gun modules and the adjacent supporting support assemblies.
- FIG. 3 is an enlarged, partially exploded perspective view of the modular spray gun manifold of FIG. 1 showing the end spray gun module and the adjacent fluid return plate.
- FIG. 4 is a perspective view of one of the supporting support assemblies of the modular spray gun manifold of FIG. 1.
- FIG. 5 is a perspective view of the body of one of the spray gun modules of the modular spray gun manifold of FIG. 1.
- FIG. 6 is a perspective view of the junction plate of the modular spray gun manifold of FIG. 1.
- FIG. 7 is a perspective view of an alternative embodiment of a modular spray gun manifold according to the present invention.
- FIG. 1 of the drawings there is shown an illustrated modular spray gun manifold 10 in accordance with the invention.
- the manifold 10 includes a plurality of spray gun modules 11 each of which includes a rectangular block- shaped body 12, a spray nozzle assembly 13 supported at one end of the module body 12, and an actuator 14 supported at the opposite end of the module body 12.
- the basic structure and mode of operation of the spray gun modules are known in the art, for example, as shown in U.S. Patent 5,707,010 assigned to the same assignee of the present application, the disclosure of which is incorporated herein by reference.
- the spray nozzle assembly 13 of the illustrated spray gun module 11 is an external mix type of spray nozzle, namely a nozzle in which liquid and pressurized air or other gases are mixed externally of a liquid discharge orifice to produce a predetermined atomized spray pattern.
- the spray nozzle assembly 13 comprises a nozzle body and an air cap 18 releaseably mounted at the discharge end of the module body by a retaining ring 19, which in this case threadably engages the module body (see FIGS. 1 and 2).
- atomizing air directed through the nozzle assembly interacts with and atomizes the discharging liquid and "fan air” directed through the air cap 18 further atomizes, forms and directs the discharging liquid spray.
- fan air directed through the air cap 18 further atomizes, forms and directs the discharging liquid spray.
- an external mix type nozzle is illustrated, it will be understood that the present invention is not limited to any type of spray nozzle.
- an internal mix type spray nozzle or any other suitable spray nozzle could be used.
- the actuator 14 which also may be of a known type, has an end cap secured by a retaining ring that threadably engages an opposite end of the module body 12, and a valve needle with a piston that is selectively moved between valve on and off positions in a high speed cyclic mode through direction of pressurized air (i.e., control air) to the piston. While in the illustrated embodiment the spray nozzle assembly 13 and actuator 14 are individually mounted on and affixed to the module body 12, alternatively, the spray nozzle assembly and actuator may be part of a unitary removable cartridge, as disclosed in application Serial No. 220,589 also assigned to the same assignee as the present application, the disclosure of which also is incorporated herein by reference. Of course, other types of actuators and spray nozzle assemblies could also be used and the present invention is not limited to any single type of actuator or spray nozzle.
- the module body 12 is formed with a plurality of respective fluid passages 20 extending transversely through opposite sides of the module body 12 that permit communication of fluids both to the spray nozzle assembly 13 and actuator 14 and through the module body 11 (see FIGS. 2 and 5).
- the module body 11 is also formed with a further return passage 20 for permitting recirculation of the liquid as explained in greater detail below.
- the manifold 10 has a lightweight, easy to manipulate and support construction with the spray gun modules 11 being connected and supported by the fluid communicating passages or conduits connecting the modules without the necessity for massive or heavy support plates or other structure. More particularly, the manifold 10 has a relatively lightweight construction that permits easy cantilever support of the manifold from a single end thereof and which can be easily disassembled for cleaning.
- the spray gun modules 11 are interconnected in laterally spaced apart relation by fluid communication and support assemblies 25 interposed between adjacent spray gun modules 11 (see FIG. 1).
- the support assemblies 25 in this case include a plurality of fluid conduits 26 for supplying liquid, atomizing air, cylinder air, and control air to the passages 20 in the module bodies as shown in FIG. 4.
- the support assemblies 25 comprise blocks 28 within which the fluid conduits 26 are embedded.
- the blocks 28 are made of a relatively lightweight material such as Teflon® or the like.
- the illustrated support assemblies have a pair of additional passages 29 therethrough which are not necessarily used to direct fluid.
- the fluid conduits 26 each preferably extend outwardly a small distance beyond the respective ends of the blocks for insertion into the passages 20 with a threadless union therebetween (see, e.g., FIG. 2). Appropriate sealing members are provided about the fluid conduits 26.
- a support and junction plate 35 is mounted at an upstream end of the manifold 10.
- the junction plate 35 in this case has an end plate portion 36 formed with a plurality of radial fluid connections 37 to which respective fluid supply lines can be connected at the end of the manifold. These connections 37 communicate with respective passages 39 that mate up with and communicate with the conduits 26 of the adjacent support assembly 25 when the manifold is assembled.
- an integrally formed mounting flange 38 can extend in axial relation to the end plate portion 36 for coupling to a pivot door or other support structure.
- an end plate 40 in this case is mounted against and closes the end of the last spray gun module in the downstream direction. It will be understood that fluid communicated to the radial passageways 37 of the junction plate 35 will communicate through the support assemblies to and through each spray gun module 11.
- a fluid return plate 50 can be provided after the last spray gun module 11 before the end plate 40 as shown in FIG. 3. In this case, the fluid return plate 50 is separated from the last spray gun module 11 by a gasket 52.
- the fluid return plate 50 includes a slot 54 that communicates with two of the fluid passages 20 in the last spray gun module 11 thereby establishing a path by which fluid can move between the two passages.
- the slot allows fluid exiting one of the passages 20 to recirculate back into the other passage 20 and from there back through the manifold 10 in the upstream direction through respective recirculation passages 20 in the other spray gun modules 11 and corresponding recirculation conduits 26 in the support assemblies 25.
- a pair of externally threaded retaining rods 42 are provided each of which extends the entire length of the manifold 10 and through the individual spray gun module bodies 12. In this case, each of the retaining rods 42 engage the junction plate 35 (see FIG.
- each support assembly 25 which house the rods (see, e.g., FIG. 4), through transverse passages 44 in the spray gun body 12 parallel to the fluid passages 20 (see FIG. 5), and through the end plate at the downstream end of the manifold (see FIG. 3).
- the passages 43 that house the retaining rods in this case do not protrude beyond the respective ends of the support assembly blocks.
- Wing nuts 48 are threaded onto the protruding ends of the retaining rods 42 to secure the spray gun modules 11 and support assemblies 25 in interposed relation between the retaining plate 40 and the junction plate 35 (see FIG. 1).
- FIG. 7 A manifold 10 having an alternative embodiment of the support assemblies 65 is shown in FIG. 7.
- the fluid conduits 26 associated with each of the support assemblies 65 are exposed.
- the conduits 26 are supported relative to each other by lightweight end plates 69 are provided at opposite ends of the support assemblies 65.
- the junction plate 35 also has a slightly different configuration and includes a mounting flange 38.
- the modular spray gun manifold of the present invention has a lightweight construction which enables its support and manipulation without the necessity for massive support bars or other structures typical of the prior art.
- the manifold also has a relatively simple construction which lends itself to economical manufacture, efficient cleaning, and easy modification for particular spray applications.
