  • Ink jet printing apparatus prior to this time has ordinarily incorporated nozzle assemblies and pumping and ink supply members as completely separate and independent structures. This has required the use of lengthy conduits or hoses, additional hardware, and more careful control of parameters such as pressure, temperature, and the like.
  • an ink jet printing apparatus has a nozzle assembly mounted on a carrier for relative'movement in relation to a document to be printed. Integrally formed with the carrier are a pump and ink supply that are relatively movable along with the nozzle assembly.
  • the arrangement results in a compact, efficient structure and provides for required adjustments such as those pertaining to the jet stream itself and the relationship of the pressurizing system to the charging coil and deflection plates as well as adjustment of stream angle relative to the paper. This insures improved print quality and reduces maintenance requirements.
  • FIG. 1 is a block diagram of an ink jet printing apparatus incorporating pressurizing systems in accordance with the present invention.
  • FIG. 2 is a perspective view of an ink jet printer incorporating the pressurizing and printing systems on a movable carrier.

  • Nozzle assembly 201 is positioned for formation, propulsion, charging, and deflection of drops in a stream 210 toward a document 212 to be printed.
  • drops are formed by vibration of crystal under control of crystal plates205a and 205b in accordance with the strength of the charge placed on the drops by electrode 135. Any drops not required for printing such as drops 21% are directed to a gutter 165.
  • Other drops, such as drops 210a required for printing are directed along various paths to document 212. Drops landing in gutter are returned to ink supply 55 and conduit 227 for recirculation through the system.
  • currents generated in gutter 165 as a result of the drops passing therethrough can be used to determine synchronization following amplification by amplifier 230 comparision by comparator circuit 231 with a reference voltage from source 232 and application of a correction signal on line 233 to sync control 216.
  • a printer unit 235 shown in more detail in FIG. 2 includes the customary keyboard 236 and various other controls found in a printer such as the IBM Selectric printer described in the various customer engineering manuals referred to previously.
  • Nozzle assembly 201 is mounted adjacent a platen 242 on which document 212 is positioned for printing.
  • Nozzle assembly 201 is fastened to a carrier 9 that is slidably movable on shaft 241 adjacent to document 212 for printing of information on a character-by-character or line-by-line basis.
  • Also positioned on carrier 9 are the pump structures 243 that are shown in greater detail in the other figures such as FIGS. 3a, 3b, 4a, 4b, Sa-c.
  • Printer unit 235 includes a left margin switch 246 and a right margin switch 247 that are activated when the carrier reaches those respective locations to indicate the beginning and end of lines on document 212.
  • -Printer 235 may be activated from a data source, not shown, that may be any of various known types, such as a computer, a communication network, a magnetic card reader/recorder, a magnetic tape reader/recorder, etc.
  • FIGS. 3a, 3b, 4a, 4b, and 5a-5c Reference is made to FIGS. 3a, 3b, 4a, 4b, and 5a-5c. Only so many of the reference numerals as are believed necessary to facilitate an understanding 'of the elevational views in FIGS. 4a, 4b, and 5a-5c are incorporated in those figures.
  • Carrier 9 is mounted in the Selectric printer frame similarly to a type head carrier.
  • Print shaft 1 in addition to supporting carrier 9, provides the rotating motion to pump charging cam 3 via sleeve 2 which is free to traverse the distance between the side frames of the support casting with carrier 9 but which also rotates with print shaft 1 upon command to refill the pump with ink.
  • Cam 3 and sleeve 2 are rotated by print shaft 1 via key 4.
  • a partial rotation of cam 3 fills the pump by rotating rocker arm 6 clockwise about shaft 7.
  • the clockwise rotation of arm 6 stretches springs 16 and 17 via arms 10 and 11 and set screws 12 and 13 and adjusting nuts 14 and 15.
  • a bellows pump is described. Diaphragm and piston type pumps may be used instead.
  • Rotating bellcrank 6 clockwise stretches bellows 28 that has its peripheral left hand flange clamped between flanges 27a and 35a of housings 27 and 35.
  • the stretching force is translated from bellcrank 6 to bellows 28 by adjustable nut 25 and plunger shaft 26 whose flange is attached to bellows 28 and whose shaft portion is guided in housing 27.
  • Housings 27 and 35 are attached via screws 29, only one being shown. Typically. in subsequent discussion. only one screw of each set is shown.
  • valve 60 When bellows 28 is elongated, valve 60 is closed by force of spring 59 and vacuum created by the pump action. and valve 37 opens compressing spring 38.
  • Ink is drawn into pump chamber in housing 35.
  • the ink is drawn from reservoir 55 thru filter 52 support screen 51 (that are mounted to tank 55 via flange 54 and screws 53) and thru hose 50 and filter 44 and support screen 42.
  • the above filter and screen and valve 37 with its spring 38 are attached to housing 35 and sealed via seal 39, spacer 40, flange 46 and screws 48.
  • cycle valve 60 is closed, the energy stored in spring 123 and bellows 121 is sufficient to maintain a stream of ink thru the bolt 95, nozzle 115, charge ring 135 to the gutter 165.
  • Capacitance or reserve bellows 121 with its spring 123 and plunger 122 are mounted to housing 62 and supported by housings 120 and 125 and screws 128. Nut 126 is used to adjust maximum downstroke of the bellows.
  • Bolt ' is attached to strap via tensioning nut 96.
  • Nut 96 is torqued the proper amount to provide correct compressive pressure on piezoelectric crystal which is captured between shoulder of bolt 95 and strap 100.
  • the assembly just described is mounted to ears of bracket 88 by screws 106. Washer 90 and 0 ring 89 seal the ink path from bracket 62 to bolt 95.
  • the right hand tennon of nozzle 115 fits into end of bolt 95. It is sealed to bolt 95 by nut 116.
  • Housing 62 is attached to housing 35 and sealed to it by 0 ring 61.
  • Valve 60 seats in housing 35 and is forced into its seat by spring 59 which seats in housing 62 thus providing a valved ink path from pump reservoir in housings 27 and 35 out thru nozzle 115.
  • valve 69 whose seat 68 is in housing 62 is to close off the ink flow from the pump and capacitance chambers thru the nozzle any time the machine is shut down or there is a power failure.
  • the valve when closed also provides a by-pass so pressure level in bolt and nozzle is immediately reduced to atmospheric pressure thereby preventing nozzle from dribbling.
  • Valve 69 also provides a by-pass from pump chamber to capacitance chamber to provide for equalizing pressure in the two chambers when valve 69 is closed and a pump stroke is initiated.
  • valve unit parts are mounted and are operated as follows: Solenoid 87 pulls link 86 which rotates bellcrank 85 clockwise, FlG. 3a.
  • the forked portion 850 of bellcrank 85 presses on disc 80 which is attached to valve stem 73.
  • This action opens valve 69, compresses spring 81 and causes the lower portion of valve 69 to seal against pliable valve seat 75 which is supported and mounted to housing 62.
  • spring 81 pressing on disc 80 actuates valves stem 73 and valve 69 upwardly so valve 69 is seated at 68.

  • Deflection plate 152 is mounted on the lower angular or curved surface of bracket 150 which in turn is attached to bracket 140 via screws 151. Adjustment is provided to permit changing the surface of deflection plates 205 relative to the ink stream.
  • brackets 140, 145 and 150 The assembly consisting of brackets 140, 145 and 150 is snapped on to bracket 137 with forks 141 and 142 fitting about tennons 136 and the inside U portion of bracket 140 encapsulating the spherical portion of bracket 137.
  • Bracket 138 is adjustable relative to charge ring 135, by manipulation of mounting screw-spring pairs 155-156, 157158.
  • Bracket 138 is now adjustably mounted to bracket 88 with screws thru slots 175 in 138 and tapped holes 176 in bracket 88. This adjustment permits setting charge ring 135 the proper distance from the end of nozzle 115.
  • Gutter 165 collects all drops of ink that are not deflected to print characters on the paper. This ink is fed thru tube 165 into reservoir 55 thru hole 166.
  • Gutter 165 is mounted in bracket 160. The gutter height can be adjusted relative to the stream of ink drops by set screw 167.
