Definitions

  • the present invention relates to fluid applicator apparatus, being more particularly directed to fluid distribution mechanisms for coating materials on surfaces (hereinafter generically referred to as sheets or sheet means such as, for example, hot melt adhesives, solvent-type pressure sensitive adhesives, resins, plastics or other fluid materials.
  • sheets or sheet means such as, for example, hot melt adhesives, solvent-type pressure sensitive adhesives, resins, plastics or other fluid materials.
  • Another object of the invention is to provide a new and improved fluid applicator apparatus of more general application, as well.
  • FIG. 2 is a longitudinal elevation ofa preferred nozzle distribution structure useful in the system of FIG. 1 and partly sectionalized to illustrate details of construction;
  • FIG. 3 is a longitudinal section upon a very much enlarged scale taken upon the line 2-2 of FIG. 2, looking the direction of the arrows;
  • FIG. 4 is a plan view of a modified multinozzle construction.
  • the invention is therein illustrated as applied to the example of the application of a pattern of intermittent adhesive coatings to sheet paper, cardboard, or similar material. It is to be understood, however, that this is only one illustrative application of the invention, in
  • a sheet 1 is shown moving in the direction of the arrow alongside the same under the control of draw rolls 3 driven from a control shaft 5 through the medium of conventional drive gears inside the gear box 7, as is well known.
  • the sheet 1 passes a fluid distribution member generally designated by the reference numeral 2 which receives fluids along lines carried within a preferably flexible duct 4 from an adhesive hot melt reservoir 6, as of the type describedin the said U.S. Pat. No. 3,323,5 ID or any other suitable type.
  • a metering pressurized pump 8 is preferably employed to introduce the hot melt fluid adhesive or other fluid under controlled metered conditions into the distribution member 2.
  • FIG. 2 The connections within the conduit 4 are more specifically illustrated in FIG. 2 wherein the adhesive or other fluid reservoir 6 is shown feeding through the metering pump 8 and a port line 4' into an inlet 9 in he distribution member 2.
  • the member 2 has an outlet 11 feeding a nozzle 13 for ultimate ejection of the adhesive upon the sheet I as successive portions of the sheet are presented to the nozzle in passing thereby or in other equivalent relative movement of nozzle and sheet.
  • the metering unit 8 may, for example, be of the type IBUPZ marketed by Acumeter Laboratories, Inc., Newton Lower Falls, Massachusetts, or any other well-known type, wherein the input drive shaft 8' thereto (FIG. 1) may be synchronously controlled, as by he belt 10 from a shaft 3 associated with the draw rolls 3, thus synchronously to adjust the metered fluid volume flow in accordance with the rate of movement of the sheet 1.
  • While the invention is also useful with more continuous coatings such as 12', it is particularly useful with patterns involving intermittent deposits.
  • Such intermittent distribution may be effected with theaid of apparatus of the type disclosed in said U.S. Pat. No. 3, l 74,689 or other similar distributors.
  • FIG. 2 it is shown, effected with the aid of a valving member 2 disposed to slide longitudinally intermediate the distribution member inlet 9 and outlet 11.
  • an opening 14 in the valving member 2' is shown permitting open communication of fluid from the inlet 9 through to the outlet 11; whereas upon operation of an air cylinder or other similar control 16 to the left, the intermediate valve member 2 will move to the left, blocking the communication between inlet 9 and outlet 11 of the distribution member 2.
  • the opening 14 will communicate the port line 4' and inlet 9 with a further opening 9' that connects back to the fluid source or reservoir 6 through a bypass return line 4".
  • the air cylinder 16 may be periodically operated by intake and exhaust conduits 18 and I8 operated from a valve mechanism 20, FIG. I, that may again, if desired, be synchronously controlled with the rate of rotation of the draw roll shaft 3' and thus with the rate of movement of the sheet 1 relative to the distribution mechanism 2.
  • a suitable device 20 for such purposes may be a cam-operated shutter valve as of the type marketed by Marsh Instrument Company, Skokie, Illinois (U.S. Pat. No. 3,020,927).
  • the restrictor section 22 is preferably located as close to the distribution member 2 as is practically feasible.
  • a novel nozzle construction 13 is connected to the outlet 11 of the distribution member 2.
  • the nozzle 13 is shown in more detail in FIGS. 2 and 3, having a first longitudinal or downward-direction flow section 13' and an orthogonally extending direction-changing expansion chamber section 13" which, as more particularly shown in FIG. 3, permits lateral expansion of the pressurized fluid in the long direction of the expansion chamber 13''.
  • a baffle wall 13" Spaced from the open end of the expansion chamber 13'', shown at the right-hand end in FIG. 2, a baffle wall 13" is disposed to define, preferably a slot aperture 30 through which the expanded fluid may be caused to eject in a substantially uniform laminar fashion upon the paper sheet I, as at 12.
  • nozzle 4 may be employed as with the nozzle located on a side or section of, for example, a hexagonal head I02, carrying other nozzles for indexing, with the apertures of each nozzle 130, 130, etc., differently dimensioned, if desired, for different deposition dimensions.
  • a further refined control is available in accordance with an additional feature of the invention in that both the volume of ejected fluid and, more particularly, the fluid ejection velocity from he aperture 30 of the nozzle 13 of the distribution member 2, can be controlled, again in accordance with variations in the rate of movement of the sheet 1, thereby to maintain uniform predetermined desired coating results.
  • This is illustrated as effected in the embodiment of FIG. 2 by opening or closing the aperture 30 as with the aid of a rotatable drive screw 30' (or any other well-known variable aperture device), under the control ofa speed converter shaft 31, FIG. I, driven by a converter 32 of any well-known type that monitors the speed of the draw rolls 3 and indicates variations to the desired degree.
  • variable aperture adjustment screw 30' The connection between the variable aperture adjustment screw 30' and the speed control shaft 31 is schematically illustrated at 33 for purposes of avoiding cluttering the drawing with known structures.
  • the aperture 30 may correspondingly be varied from 0.020 inches to .030 inches, more or less.
  • the cross dimension of the restriction 22 may synchronously correspondingly be varied in well-known fashion as by the adjustment screw 34, FIG. 2, again controlled by a link 33' from the speed converter shaft 31.
  • Fluid applicator apparatus having, in combination, a source of pressurized fluid, a distribution member provided with inlet and outlet means and intermediate-valving means movable between two positions to open and block fluid communication between the inlet and outlet means, respectively, means for connecting the source of fluid with the inlet means to supply fluid to the distribution member, nozzle means connected with the outlet means to eject fluid from the distribution member when the intermediate means is in a position permitting fluid communication of the inlet and outlet means, the nozzle means having a longitudinal flow section and a direction-changing expansion chamber connected thereto for laterally expanding the fluid flow and aperture means for directing the laterally expanded fluid as a substantially uniform flow.
  • said aperture means comprises a wall spaced laterally from said expansion chamber to define the aperture therebetween and directing the expanded fluid outward therethrough.
  • Apparatus as claimed in claim 2 an inwhich means is provided for varying the space defined by the said aperture means to control at least one of the fluid volume flow and the fluid velocity as ejected.
  • Fluid applicator apparatus having, in combination, a source of pressurized fluid, a distribution member provided with inlet and outlet means, means for connecting the source of fluid with the inlet means to supply fluid to the distribution member, nozzle means connected with the outlet means and having aperture means to eject fluid from the distribution member, moving means for presenting successive portions ofa sheet means to the nozzle means at a predetermined rate, and means responsive to said moving means for controlling the velocity of the ejected fluid in accordance with said rate.
  • Fluid applicator apparatus having, in combination, a source of pressurized fluid, a distribution member provided with inlet and outlet means and intermediate-valving means movable between two positions to open and block fluid communication between the inlet and outlet means, respectively, means for connecting the source of fluid with the inlet means to supply fluid to the distribution member, nozzle means connected with the outlet means to eject fluid from the distribution member when the intermediate means is in a position permitting fluid communication of the inlet and outlet means, means for moving said valving means between its said two positions for intermittent periods, said connecting means comprising an inlet line from the source to said inlet means and a bypass return line to the source, and restriction means disposed in said return line substantially to match the pressure that exists between the source and the nozzle means when fluid is ejected therefrom, during the intermittent periods of no ejection.
