Abstract: A gun mount for a spray gun includes a rigid bracket that is installed on a rigid vertical support such as a gun mover. The bracket securely mounts the guns so as to reduce vibration and swaying during a spraying operation, even when the guns are being vertically moved by an oscillator. A position label or other suitable indicia is provided on the bracket so that the gun mount position can be recorded and thereby accurately repeated during subsequent installations. The bracket in one embodiment includes a series of vertical and horizontal mounting holes that permit a gun body to be installed at a desired vertical and horizontal orientation. A gun blow off arrangement is also provided for mounting associated pairs of air nozzles in position to blow powder from gun exterior surfaces. The associated pairs of air nozzles are mounted on a common bracket that can be selectively and slideably positioned on a channel support. An air nozzle positioning indicating device is provided to accurate position and record the position of the air nozzles for particular gun positions.

Abstract: A powder spraying gun generates a desired pattern of electrostatically charged particles for coating a workpiece without rotating parts or particle deflectors. The powder pattern is generated with a funnel-shaped output in conjunction with air introduced into a powder charging chamber of the gun in a tangential swirling motion. The swirling air is additionally used to purge agglomerated powder particles from the charging electrodes in the charging chamber. The charging chamber surface is fashioned from material exhibiting low friction or high resistance to powder impact fusion.

Abstract: A spray gun includes a handle portion and an extension portion. A nozzle is connected with an outer end of the extension portion. An electrode assembly is disposed in the extension portion to establish an electrical field to electrostatically charge particles of coating material. A coating material flow control member and a purge air flow control member are disposed on the handle portion. Operation of either one of the two flow control members actuates a membrane switch assembly. Operation of the purge air flow control member directs the flow of air to the coating material passage in the extension portion to remove excess coating material from the passage and from the nozzle. Different size hand grips may be mounted on the handle portion of the spray gun to accommodate operators having hands of different sizes. Passages for air and electrical conductors are formed in the handle and extension portions of the spray gun by cooperation between outer side walls of the handle and extension portions and inner wall structures. A voltage multiplier unit in the extension portion of the spray gun is exposed to a flow of air to transfer heat from the voltage multiplier.

Abstract: An electrostatic spray gun apparatus includes a spray gun housing and a nozzle attached to a spray end of the housing, and a powder path that extends in a substantially straight line along an axis of the housing from the powder inlet to the powder outlet. The powder path is in the form of an enclosed smooth powder passage that is substantially continuous and uninterrupted from the powder inlet to the powder outlet to eliminate substantially all recesses or gaps that could capture or trap powder. The powder passage is formed by a plurality of tubular segments that are aligned along the housing axis and abut end to end. that when assembled in the housing axially compress the segments together to substantially eliminate dead spots or recesses to form the continuous smooth powder path. A gun purge function is provided that allows a purge line to be installed on the gun assembly. A cartridge valve and conductor assembly is provided between the gun electrode in the nozzle and the output of the voltage multiplier. The cartridge includes a conductive path to provide electrical continuity from the multiplier to the gun electrode, and also includes valve, preferably in the form of a stem check valve, that closes when the gun electrode is removed or at least unseated from the nozzle. The gun also includes a tube mount arrangement wherein the tube mount is rigidly held together with the gun housing in axial compression by a tie bar.

Abstract: The present invention describes a process for the application of a powder coating to a non-conductive substrate by first exposing the non conductive substrate to a combination of steam and heat at temperatures between 70° C. and 140° C. for a period between 5 seconds and up to 10 minutes, followed by electrostatic application of a powder coating to the substrate which is grounded; this simple and reliable pre-treatment method allows an efficient application of powder coatings to non-conductive substrates resulting in uniform and even deposition of the powder coating over the whole surface including edges and with no adverse effects on the subsequent curing of the powder film.

Abstract: A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots. Among other benefits, such flow control features reduce any tendencies for flow separation of the primary fluid in the diffuser.

Abstract: The invention provides a gun for spraying a powder onto a work piece to form a coating and includes a pistol-grip housing having an air valve coupled to a source of pressurized air. The housing also supports a source of variable electrical potential. A powder container is disposed in fluid communication with the air valve so that powder within the container may be fluidized by air from the source of pressurized air when the valve is opened. A nozzle is positioned within the housing and includes a central passageway having an open end and disposed in fluid communication with the powder container. The central passageway frictionally imparts a net electrical charge of a first polarity to a first portion of the powder when the first portion of the powder contacts the surface during the spraying. A discrete member is positioned within the central passageway and is capable of imparting a net electrical charge of a second polarity to a second portion of the powder when the second portion of the powder contacts the tubes during the spraying. An emitter rod is positioned within the central passageway and comprises a proximal end and a distal end, where the proximal end is interconnected to the source of variable electrical potential.
