Definitions

  • ABSTRACT Method of operating a drop generator while avoiding spattering during start up and termination of operations.
  • the method includes pressurizing the drop generator manifold with air or other gas and with a flushing liquid formulated to leave substantially no residue upon evaporation, before pumping coating material to the manifold.
  • a flushing liquid formulated to leave substantially no residue upon evaporation, before pumping coating material to the manifold.
  • the flow of coating material to the manifold is replaced with a flow of flushing liquid and the flow of flushing liquid is then terminated and, simultaneously, an evacuation line leading to a low pressure source is opened.
  • An electrostatic deflecting field is set up downstream of the charge rings and all drops which receive a charge while passing through the charge rings are deflected from their trajectory by the deflecting field.
  • a catcher is also associated with the system to catch those drops which it is desired to prevent from reaching the receiving member. In this way it will be seen, a patterned coating, such as printing, is applied to the receiving member.
  • the coating material does not contact the filament forming orifices until the pressure necessary to form a free filament of coating material has been reached in the manifold. This is accomplished by first pressurizing the manifold with a gas, such as air, to a pressure at least equal to or preferably substantially above the operating pressurerequired for production of a free standing filament of coating material.
  • a gas such as air
  • the coating material is pumped to the manifold at or above operating pressure and, since the manifold has already been pressurized before introducing the coating material, the coating material arrives at each of the orifices at or above operating pressure and immediately forms a free standing filament issuing from the orifice and forming a series of discrete drops.
  • a flushing liquid characterized by a substantial absence of residue upon evaporation may be pumped to the manifold before the coating material is pumped thereto.
  • the liquid will quickly evaporate, with negligible residue resulting.
  • free standing filaments of flushing liquid are established at each of the orifices the supply of flushing liquid to the manifold is terminated and simultaneously replaced with a flow of coating material at or above operating pressure. Also, at this point any gas which remains entrained in the manifold may be bled therefrom.
  • the supply of coating material is terminated and simultaneously replaced with a supply of the flushing liquid. Thereafter, the supply of flushing liquid is terminated and simultaneously a line is opened from the manifold to a waste sump operating at a pressure substantially below atmospheric. This sudden reduction of pressure in the manifold is sufficient to terminate the jets of flushing liquid without producing masses of liquid at the orifices or the formation of erratic drops.
  • Air may conveniently be used as the pressurizing gas and the flushing liquid may be any liquid which evaporates without appreciable deposit of residue.
  • the flushing liquid may be any liquid which evaporates without appreciable deposit of residue.
  • a mixture of approximately 50 percent distilled, deionized water and 50 percent denatured alcohol appears satisfactory.
  • FIG. 1 is a somewhat schematic showing of a drop generator in accordance with the present invention
  • FIG. 2 is a cross sectional view taken on line 2-2 of FIG. 1;
  • FIG. 3 is an enlarged cross sectional view showing the formation of coating material accumulations that result when pressure is allowed to build up gradually at the orifices; and 7 FIG. 4 is an enlarged cross sectional view similar to FIG. 3 but showing the formation of filaments and drops of coating material in accordance with the present invention.
  • a drop generator in accordance with the present invention may include manifold 12 having a chamber 14 formed therein. Mounted beneath the manifold 12 is an orifice plate 16, a spacer plate 18, a charge ring plate 20, a pair of deflecting'electrodes 22 attached to the charge ring plate, as at 23, and a catcher 24 spaced from the electrodes by mounting means 26.
  • Coating material supplied to the chamber 14 will be ejected through the orifices 28 to, form fine filaments which break up into discrete dropsof coating material. Itis desirable that if a charge is to be applied to a particular drop it is applied at approximately the point at which the drops'break from the filaments.
  • the spacer plate l8 having a series of openings 30 formed therethrough, spaces the charge ring plate at the proper distance from the orifice plate 16 such that the charge rings 32 charge each of the drops of coating material just as they break fromtheir respective filaments of coating material.
  • the coating material will tend to form pendulous masses, as indicated at 38 in FIG. 3 of the drawings,
  • chamber 14 is prepressurized with the system shown somewhat schematically in FIG. 1 of the drawings.
  • a gas port 40 is provided leadingto one end of the chamber 14 while a liquid port 52 communicates with the opposite end of the chamber.
  • a gas such as air, is pumped through line 44 and valve 46 by means indicated at 4 8.
  • a second line 50 also communicates with the gas port 40 and is provided with a valve 52 and a source of negative pressure as indicated at 54.
  • a bleed line 55 also branches from port 40, controlled by valve 56.
  • Liquid port 42 may be fed by line 57, which includes a'valve 58 and is connected with means, as indicated at 60, for pumping a flushing liquid through the line 57. Also connected to port 42 is a line 62, controlled by valve 64, and through which coating material may be.
  • valve 46 is opened, allowing air or other pressurizing gas to be pumped through line 44 by means of pump 48 at a pressure in excess of operating pressure.
  • the pressure and flow rate of, gas issuch that the pressure in the chamber 14 quickly rises to a pressure above normal operating pressure, despite the escape of gas through the orifices 28.
  • Coating material may then be introduced into the system by opening valve 64 and pumping. the coating at or above operating pressure through liquid port 42.
  • the coating material will advance through the chamber 14 in a coherent wave, from right to left as seen in FIG. 1 of the drawings. Since it is at or above operating pressure as it reaches each of the orifices, free standing jets are formed, as seen at 70 in FIG. 4 of the drawings,
  • valve 46 is closed about 0.3 opening of valve 64. 1
  • valves4'6 and 58 are opened, allowing gas to be pumped from source 48 and a flushing liquid to be pumped from source 60, both the gas and flushing liquid being at 'a pressure in excess of operating pressure. Again, the liquid entering the chamber 14 will advance as a coherent wave, replacing the gas flow at each of the orifices 28 with a liquid flow at or above operating pressure.
  • valve 64 is opened and simultaneously valve 58 is closed. This allows coating material at or above operating pressure. to flow through line 62 and liquid port 42 into the chamber l4, displacing any .flushing liquid therein with coating ,material. Thereafter, any air or other gas which may remain in the system may be bledout through line and valve 56.
  • valve 64 When it is desired to terminate operation of the drop generator, valve 64 is ,closed and valve 58 opened, causing the flow of coating material to be replaced by a flow of flushing liquid. Thereafter, valve. 58 is closed and valve 52 is simultaneously opened, causing both the flow of flushing liquid to terminate and the evacuation of the system to a waste sump operating at a pressure substantially below. atmospheric pressure. This sudden reduction in pressure in the system is sufficient to terminate the jets without producing erratic drops below the orifices or allowing coating material to collect in pendulous masses about the orifices.
  • the present invention provides method and apparatus for operating a drop generator without the problems normally associated with start up and shut down procedures.
  • a method of commencing operation of a drop generator which includes orifice defining means and a manifold communicating with said orifice defining means for providing a supply of liquid coating material thereto comprising:
  • step of pressurizing said manifold with gas comprises:
  • step of introducing coating material into said manifold comprises:
  • step of adding flushing liquid comprises:
  • step of evacuating said manifold comprises:
  • step of pressurizing said manifold with a gas comprises:
  • a method of operating a drop generator which includes an orifice plate having means defining a plurality of small diameter orifices therethrough, a manifold communicating with said orifices for providing a supply of coating material thereto, and a gas port and a liquid port communicating with said manifold comprising:
