Definitions

  • Coating apparatus constructed in accordance with the above noted related application divides a supply of coating material into a series of discrete jets which tend to break down into a series of small drops. The drops are then directed through a charge ring which may be selectively activated to either impart or not impart an electrostaticcharge to each drop.
  • the drops then pass through an electrostatic field and are either deflected-or not deflected depending upon whether or not they have been charged by the charge rings.
  • a catcher is pro- 'videdbeneath the electrostatic field and prevents drops which are deflected by the field from impinging upon-the web or other article being coated.
  • the dimensions of components must be controlled with great precision.
  • the charge ring through which the droplets pass may be on the order of 0.023 inches in diameter while the orifices from which the coating material is ejected may be only 0.0015 inches in diameter.
  • the components of the coating head are each manufactured separately and then joined in laminar relationship to form the completed coating head.
  • each of the components may be manufactured with the degree of precision required for successful operation of the system. Constructing the coating head as an assembly of components also renders the task of insuring that each of the components is free of foreign material less complicated than would be the case if it were attempted to construct the printing head as a single unit or one or two subunits.

Adjacent one end of the inlet plate a cleanout port 35 formed extending from one side of the plate into the slot 31 and a cover plate 36 and gasket 37 are secured over port 35 by means of bolts or the like 38.
  • an orifice plate 40 Located beneath the inlet plate 30 an orifice plate 40 is positioned having a, series of openings 41 formed therein at regularly spaced intervals in substantial concentricity with the apertures 32 in the plate 30.
  • a spacer plate 42 having a series of openings 43 formed therein in line with openings 41 is mounted beneath orifice plate 40 and serves to space a charge ring plate 50 from orifice plate 40a predetermined distance for a purpose to be presently described.
  • the charge ring plate 50 formed of a dielectric material, is positioned beneath the spacer plate 42 and is provided with a series of openings 5] extending therethrough, concentric with and appreciably greater in diameter than, the orifices 41.
  • a discrete application of an electrically conductive coating material surrounds each opening 51, in circular outline, and covers the wall thereof to form a charge ring 52 (FIG. 5).
  • Also applied to the plate 50 are a series of discrete lines of electrically conductive coating material which form conductors extending from each charge ring 52 t o a connector 54 mounted on charge ring plate 50 adjacent each end of a clamp plate 60.
  • Connectors 54 engage complementary connectors 55, which in turn are in circuit with control unit 56 by means of cables 57.
  • the charge rings 52 and conductors 53 can quite conveniently be manufactured using conventional printed circuit techniques although it will be appreciated that a somewhat higher degree of precision will be required than is usually necessary in printed circuit manufacture.
  • the clamp plate 60 similarly to the plates 30, 40 and 50, has a series of openings 61 extending therethrough which are substantially concentric with the openings 32, 41 and 51.
  • a pair of electrodes 70 are attached to the lower surface 63 of the clamp plate 60 by means of a pair of pins 71 having enlarged portions 72 attached to each of the electrodes 70 and abutting the lower surface 63 by means of the shoulder 73 formed by the enlarged portion.
  • Each of the electrodes may conveniently e constructed of a resin impregnated fibrous material and provided with a coating of an electrically conductive material 74 along opposing faces thereof.
  • each of the electrodes 70 is formed throughout a major portion of its length with triangularly shaped cross section 75 while distal portions 76 of each electrode are of rectangular cross section and receive the lower ends of the pins 72. It will also be noted that the lower outermost corner of each of the electrodes is beveled as at 77 and that leads 78 are attached to the'electrically conductive coatings 74 and to a source ofelectrical energy 79.
  • a pair of brackets 80 are also attached to the lower surface 63 of the clamp plate 60 and extend downwardly to support the catcher 81 having a blade 82 projecting outwardly thereof and at a slight angle to the horizontal. At least the upper surface and preferably both surfaces of the blade 82 are covered with a porous material, such as screening, to permit any drops of coating material which strike the blade to move inwardly into the interior of the catcher 81 from whence they are evacuated by the vacuum pump 83.
  • the bracket 80 is preferably provided with adjusting means to permit limited movement of the catcher transversely of the coating head.
  • the manifold 'and the plate members 30, 40, 50 and 60 are provided with a series of aligned bolt holes 90 along their edges to provide a series of continuous passages 91 through the components of the coating head for reception of the assembly bolts 92.
  • Bolts 92 have threaded ends 93 and clamp plate 60 is provided with threaded openings 94.
  • coating material is delivered through the conduit 13 into the chamber 11 of the manifold and thence out through the opening 12 and the filter plate 20.
  • the filter plate serves to screen out any particles which may be large enough to obstruct orifices 41 during passage therethrough. By positioning the filter plate in proximity to the orifice plate, the danger of coating material having foreign particles therein reaching and clogging the orifices in the plate is reduced to a minimum. While from a filtering standpoint, it would be most desirable to have the filter plate immediately upstream of the orifices 41, it will be appreciated that faceto-face contact betweenfilter plate 20 and orifice plate 40 might result in partial blockage of orifices 41.
  • the inlet plate 30, with the chamber provided by the slot 31 is positioned between the filter and the orifice plate. Additionally, to channel the flow from the slot 31 and inhibit the formation of cross flows, the coating material is delivered from the slot 31 to the orifices 41 by means of the passages 32.
  • an externalstimulation is applied to the coating head.
  • this may take the form of a sonic vibrator 100 attached to the manifold 10 and imposing a sonic signal of a predetermined frequency on the system
  • the signal may be an electric signal applied to the jets as they leave the orifices 41 by means of an electrohydrodynamic plate 101 (FIG. 2) which may be substituted for spacer plate 42 (FIG.
  • Electrohydrodynamic plate 101 is preferably provided with an electrically conductive coating on the upper surface thereof and an insulating coating over the electrically conductive coating. Stimulation is achieved by connecting the conductive coating to an oscillating voltage source and thereby producing traction forces at the surfaces of the unbroken fluid filaments.
  • Control unit 56 controls the charge rings 52 and causes each drop passing through each of the charge rings to be charged or not, as desired. If a drop is charged, as it passes between the electrodes 70 it will be deflected from its normally vertical path a slight amount, to the right as seen in FIG. 2, where it is caught by the blade 82 of the catcher 81. Conversely, if the charge ring does not charge a particular drop it will continue in a substantially vertical path and be imprinted on the web or the like W.
  • the screen 20 is 0.001 inches thick and the central portion thereof provided with 41,000 holes of one-half mil in diameter and arranged in a 90 array.
  • the inlet plate is 0.250 inches thick and has 50 passages 32, each 0.0635 inches in diameter and spaced on 0.1000 inch centers.
  • the orifice plate is 0.011 inches in thickness and is provided with 50 orifices of 1.5 mils in diameter. If an electrohydrodynamic plate 101 is utilized, this plate may be 0.105 inches in thickness and have a series of 50 openings therethrough of 0.040 inches in diameter.
  • the charge ring plate is 0.093 inches thick and also has 50 holes 51 therethrough of 0.025 inches in diameter.
  • the clamp plate 60 which also serves as an insulating shield between the charge ring plate and the electrodes 70, may be seven sixty-fourths of an inch in thickness with 50 openings 0.0635 inches in diameter extending therethrough.
  • the electrodes may be 0.500 inches in thickness and spaced apart a distance of 0.065 inches.
  • the web W of paper or the like is trained past the coating head at an appreciable angle to the horizontal.
  • This arrangement lessens the tendency of the droplets projected onto the web to assume a noncircular shape and gives a more symmetrical imprint.
  • the corners of the electrodes are beveled as at 77 to permit the coating head to be positioned beveling of the right-hand electrode as seen in FIG. 1 has no effect upon the proximity of the coating head to the web, it will be appreciated that by manufacturing all electrodes identically the necessity for stocking two different types of electrodes is eliminated.
  • the filter plate 20, inlet plate 30 and orifice plate 40 are assembled on a jig in proper position with respect to each other.
  • a cleaning fluid is then pumped through the filter plate 20 and into the slot 31 and compressed air is pumped through the orifices 41; the air and cleaning fluid exiting the inlet plate through the cleanout port 35.
  • the cover plate 36 is attached to the inlet plate and the remaining components of the coating head stacked on a jig in their proper position with respect to each other.
  • Bolts 92 are then placed in each of the passages 91 with the screwthreaded lower end 93 of each bolt engaging complementary threads 94 in the openings in the clamp plate.
  • the electrodes are then attached to the assembly by inserting the pin 71, which is coated with a resilient material, into the openings in the lower surface of the clamp plate where they frictionally engage the walls of the openings.
  • the catcher 81 is next attached to the clamp plate and precisely positioned by means of the brackets just to one side, the right-hand side as seen in FIG. 2, of the path the nondeflected drops take from the orifice 41. It will be noted that by forming the electrodes 75 as triangular in cross section throughout most of their extent, the space between the electrodes and the bottom of the clamp plate 60 may be readily cleaned.
  • the present invention provides a laminated coating head in which each of the components thereof may be manufactured separately with the high degree of precision necessary for a system of this type. Additionally, the system may be readily cleaned both before assembly and after, and means are provided for filtering the coating material immediately upstream of a majority of the components of the coating head. It will also be noted that the unit is exceptionally compact and therefore ideally suited for suspension over a moving web or the like and yet may be readily dismantled if necessary for cleaning and repair.
