Definitions

  • This invention relates to electrostatic spray systems and particularly to an improved nozzle assemby for electrostatic spray guns. More specifically, this invention relates to an external air atomizing nozzle assembly for electrostatic spray guns such as that disclosed in United States Patent No. 3,747,850 or United States Patent No. 4,273,293.
  • a fluid coating material such as paint, varnish, lacquer and the like is passed through the barrel of a spray gun, into a fluid nozzle which is threaded at its rear into a counterbore in the forward end of the barrel, and through and out of a small diameter bore in the nozzle tip at the forward end of the nozzle.
  • An air cap surrounds the forward end of the nozzle and includes a central bore surrounding the tip of the nozzle so as to define an annular air passage around the nozzle tip. Air issuing from this annular passage impacts with the stream of material issuing from the material orifice of the nozzle to at least coarsely atomise the material stream.
  • a trigger operated valve controls the flow of air through the atomising air passage, and a manually adjustable valve controls the amount of air issuing from the horn of the nozzle and thus the degree of "fan" formed by the atomised spray.
  • This solution comprises accurately positioning the central bore of the air cap around the nozzle tip by machining a plurality of axially aligned holes evenly spaced about the circumference of the bore and having those holes intersect the bore so that the holes define a plurality of uniformly dimensioned, circumferentially spaced ribs between the holes. These ribs are engageable with the peripheral surface of the nozzle tip to align the centre axis of the nozzle concentric with the centre axis of the air cap bore.
  • Still another objective of this invention has been to provide an electrostatic air spray nozzle assembly which is not subject to the problems described hereinabove and specifically, which is not brittle and thus subject to breakage, is not subject to deterioration by solvents, is not subject to plastic flow during production, and which may be reproduced under production manufacturing conditions.
  • an electrostatic air spray nozzle assembly in accordance with the invention which is made from polyamide-imide resin (commonly identified as "Torlon”).
  • Teorlon polyamide-imide resin
  • Such air spray nozzles are not brittle and subject to becoming easily broken, are not subject to plastic flow during machining, and are resistant to solvent attack. Consequently, such "Torlon” air spray plastic nozzles may be made to close tolerances and specifications under production conditions and will spray substantially identical spray patterns from one nozzle to the next.
  • the gun 10 illustrated in Figure 1 of the drawings is an air operated electrostatic spray gun which relies upon the impact of an air stream with liquid stream to effect atomisation of the liquid stream. While the invention is described as applied to an air gun, it should be understood, though, that the invention is equally applicable to all electrostatic spray guns or to spray systems in general.
  • the gun 10 shown in phanton in Figure 1 is described in detail in our United States Patent No. 3,747,850.
  • the gun is generally described here only for purposes of illustrating the application of the present invention.
  • the gun 10 comprises an electrically conductive metal handle assembly 11, an electrically insulative barrel assembly 12, and an insulative nozzle assembly 13. Paint or other spray material which may be in the nature of a coating, varnish, or lacquer (referred to in regard to this invention generically as paint) is supplied to the gun from an external reservoir or tank (not shown) through a material passage 14. A high voltage source of electrical energy is supplied to the gun by a cable 15 from an external electrical power pack (not shown).
  • the handle assembly 11 is generally made from a metal casting and incudes an air inlet 16, a trigger actuated internal air flow control valve 17 and a trigger 18 for controlling the flow of air through the valve 17.
  • an adjustable air valve 20 in the gun handle for controlling the shape or "fan" of the spray emitted from the gun.
  • the air inlet 16 opens into a generally vertical air passage in the handle 11 which communicates through the air flow control valve 17 with a pair of internal passages 22, 24 passing through the barrel 12 of the gun and terminating at the forward end of the barrel 12 ( Figure 2).
  • the passage 22 provides atomising air while passage 24 provides the fan-shaping air.
  • the flow of air through passages 22, 24 is controlled by the trigger operated air control valve 17 while the flow of fan air through the passage 24 is further controlled by the fan control valve 20.
  • the nozzle assembly 13 is made from an electrically non-conductive material. It comprises a nozzle 26 which is threaded at its rear 28 into a counterbore 30 in the forward end of the barrel 12. Nozzle 26 has six circumferentially spaced axial passages 32 which open into the rear of the counterbore 30 which in turn communicate with the air passage 22 such that atomising air passing through the passage 22 may enter and pass through the axial passages 32 in the nozzle and into an internal chamber 33 surrounding the forward end 34 of the nozzle 26.
  • the nozzle 26 also has a central axial passage 35 communicating with a material flow passage 36 in the barrel 12 for supply of liquid or fluid via the passage 14 ( Figure 1) from the tank or reservoir.
  • the forward end 34 of the nozzle is generally tapered and terminates in a nozzle tip 38 having a small diameter orifice 40 through which the coating material is emitted.
  • a hexagonal nut 60 is formed on the periphery of the nozzle. This nut facilitates threading of the threaded rear 28 of the nozzle into the threaded counterbore 30 of the gun barrel 12.
  • the flats 61 of this nut 60 have their intersecting corners rounded or radiused as indicated at 62.
  • these radiused surfaces 62 may function as a press fit surface on the front of the nozzle 26 engageable with a press fit internal diameter surface of the air cap.
  • a cylindrical section 63 of the nozzle of the same radius R as the rounded corners 67 may serve the same function or act to supplement the same press fit function.
  • a material ionising electrode or antenna 42 is mounted on the centre axis of the nozzle and is held in place in the passage 35 by means of a non-conductive holder 44 ( Figure 7). Electrical power is supplied to the electrode 42 which protrudes from the orifice 40 of the nozzle tip 38. This power is supplied generally from the electrical power pack which is connected to the gun via a cable 15 which is connected to the electrode 42 via an insulated cable 46 and spring 48.
  • the air cap 50 surrounds the forward end 34 of the nozzle 26. It includes a central bore 52 through which the nozzle tip 38 extends, a pair of fan control ports 54, one located on either side of the bore 52, two pairs of recessed fine atomising ports 56, and a pair of ports 58 in each air horn 59.
  • the surface of the central bore 52 is spaced from the internal surface of the nozzle tip 38 such that an annular air flow passage 64 is defined therebetween. This annular air passage 64 opens into the internal air chamber 33 such that air flow into the chamber 33 exits through the annular passage 64.
  • a flange 65 Extending inwardly into the air chamber 33 of the air cap 50, there is a flange 65.
  • This flange has an internal diameter D the same as or slightly smaller than the external diameter of the cylindrical section 63 of the nozzle and between the rounded corners 62 of the nut section 60 of the nozzle such that when assembled, the flange 65 is press fit onto the nut section 60 and/or the cylindrical section 63 of the nozzle 26.
  • This press fit enables this air cap 50 to be concentrically mounted onto the nozzle with the axis of the air cap bore 52 nearly perfectly concentric with the axis of the nozzle 26 and nozzle orifice 46.
  • the press fit surfaces thus align the nozzle such that the centre axis of the material orifice 40 is on the centre axis of the central bore 52.
  • the co-action of the fluid tip nozzle with the air cap thus provides an annular air flow passage 64 uniformly spaced around the fluid tip nozzle thereby producing a uniform atomising air flow pattern.
  • FIG. 3A in the prior art, the nozzle end 70 of the fluid tip 72 extends through a central bore 74 in the air cap 76 which has a diameter greater than the outside diameter of the nozzle 70 to form an annular air passage around the nozzle.
  • the fluid tip 72 is supported at points removed from the nozzle end 70 and because of inaccuracies in manufacture and dimensional instability, it is clearly not aligned in the central bore to provide a uniform annular air passage.
  • the misalignment of the nozzle in the central bore results in a lack of concentricity of the air passage 74 about the nozzle and therefore non-uniform atomisation of the material exiting the nozzle.
  • the nozzle assembly of tne present invention by virtue of the cooperation of the air cap 50 with the fluid tip nozzle 38 provides uniformly dimensioned air flow of passage 64 around the nozzle.
  • FIGS. 4A and 4B Still another prior art assembly is illustrated in Figures 4A and 4B.
  • a plurality of circumferentially spaced holes 80 whose axes are aligned with the axis of the central bore 52 are machined in the air cap 50.
  • These holes 80 intersect the circumference of the central bore 52 so as to define a series of circumferentially spaced gas flow passages with spaced radially extending ribs 84 therebetween.
  • the nozzle portion of the fluid tip 26 extends through the central bore 52 and the ribs 84 engage its outside diameter.
  • the ribs 84 align the nozzle such that the centre axis of the fluid orifice 40 is on the centre axis of the central bore 52.
  • the difficulty of this prior art structure is that the holes 80 are extremely difficult an expensive to machine and the ribs 84 partially obstruct the flow of air from the chamber 33 prior to engagement with the fluid stream emitted from the orifice 40.
  • the nozzle assembly of this application with its press fit surfaces on the outside diameter of the front of the nozzle 26 and inside diameter on the air cap 50 for effecting concentricity of the nozzle tip and air cap 50 and thus a uniform concentric air flow passage 64 about the nozzle tip 38, is less expensive to manufacture, maintains better concentricity of the assembled parts when produced on a production basis, and does not partially obstruct the air flow passage surrounding the nozzle tip.
  • the air cap 50 is mounted to the gun 10 by means of an annular retaining ring 66.
  • the retaining ring 66 is also made from an electrically non-conductive plastic material. It is threaded over a threaded section of the barrel 12 at one end and at its other end has an annular lip 67.
  • the retaining ring 66 although rigid is sufficiently flexible at the lip 69 to permit the air cap 50 to be snapped into position with the lip 67 engaging a ring 68 on the outside surface of the air cap 50 such that the air cap is securely retained and sealed against escape of air to the atmosphere.
  • the nozzle 26 and air cap 50 components of this nozzle assembly 13 are made from a polyamide-imide thermoplastic resin which is available commercially under the name "Torlon” from Amoco Chemical Corporation, 200 East Randolph Drive, Chicago, Illinois 60601.
  • Teorlon a polyamide-imide thermoplastic resin which is available commercially under the name "Torlon” from Amoco Chemical Corporation, 200 East Randolph Drive, Chicago, Illinois 60601.
  • the chemistry and properties of polyamide-imide are discussed at page 42 of the "Modern Plastics Encyclopaedia 1981-82" published by McGraw-Hill, Inc., 1221 Avenue of Americas, New York 10020. The disclosure of this portion of the Modern Plastics Encyclopaedia is hereby incorporated herein by reference. Further various grades of the material “Torlon” are discussed in the publication entitled “Torlon® Technical Data & Applications Information” (Publication No.
  • the invention has been described as being manufactured from pure or substantially pure polyamide-imide resin. It is within the scope of this invention though to manufacture the nozzle and air cap of this invention of a filled polyamide-imide resin containing a filler material.
