Definitions
- This invention relates to a new painting or coating machine wherein, through the utilization of piezo-electric etfect, magnetostriction effect, and other phenomena, paint is supplied to a vibrating body which undergoes ultrasonic-wave vibration, and the paint is rendered by ultrasonic-wave energy due to this vibration into fine particles of a state of mist and caused to be sprayed uniformly over a wide area onto the article being painted or coated.
- the present invention seeks to eliminate the abovedescribed disadvantages of the conventional electrostatic painting machines by fixing a vibrating plate to an ultrasonic-wave vibrating element or transducer of the magnetostriction or electrostriction type excited by an ultrasonic-wave generator, transforming paint, which is caused to flow in a film state onto the surface of this vibrating plate, into fine particles through the vibratory action of this plate, and forcing these fine paint particles to fly in the direction of the sound wave progagation. Accordingly, the paint in a state of fine particles is projected with high eflieciency to the intended points on the article being painted. Moreover, since the propulsion velocity of the paint particles is high, the use of Furthermore, in impressing a direct-current, high voltage in order to promote the projection of the paint in an auxiliary manner,
- the paint is already transformed into a mist by ultrasonic-wave energy and has ample initial velocity, such a high direct-current voltage (70 to 120 kilovolts) as is required in, the case of the conventional rotating atomizing head cups in electrostatic painting machines is unnecessary, and a direct-current voltage (approximately 35 kilovolts) which is of an order suflicient merely to charge the ejected particles electrostatically is suflicient. Accordingly, the painting machine according to this invention has high industrial worth due to such advantageous features as greatly reduced equipment cost, safe operation for personnel, and reduction. of fire hazard.
- the paint which becomes stagnant at such points hardens and sticks, thereby obstructing the free vibrating of the vibrating plate, or moves to a neighbouring point of high concentration of ultrasonicwave energy and is ejected as large drops. If, in order .to accomplish effective atomization, a small quantity of the liquid is caused to flow out onto the vibrating plate, atomization will occur promptly only in the vicinity of the flow-out opening. On the other hand, if the liquid is caused to flow out at a high rate, the liquid film in the vicinity of the flow-out opening will become thick, and large drops will be ejected together with the atomized mist.
- the painting machine of the present invention is adapted to vary the ultrasonic- Wave freqeuncy, which excites the vibrating element or transducer, at a suitable periodv within. a range wherein the ultrasonic-wave output is not greatly reduced, and, by preventing points of low and high concentration of the ultrasonic-wave energy developed on the vibrating plate from becoming static, atomization is caused .to be accomplished at any point on the vibrating plate.
- the atomization is accomplished uniformly by supplying the paint continuously to the vibrating plate, periodically stopping the supply of ultrasonic-wave energy, then resupplying the ultrasonic-wave energy after a uniform spread of the paint film has been formed over a predetermined area of the vibrating plate, and atomizing and dispersing this paint with one action.
- It is an object of the present invention to provide a new ultrasonic-wave painting machine wherein a vibrating plate is fixed to an ultrasonic-wave vibrating element driven by an ultrasonic-wave generator, and paint supplied to the said vibrating plate is caused, by the deflection of the vibrating plate due to the ultrasonic-Wave energy and low and high concentration of the ultrasonic- Wave energy within the vibrating plate, to be atomized in fine particles of uniform size from a wide area of the said vibrating plate so as to be projected onto an article to be painted.
- FIG. 1 is a perspective View, in diagrammatic form and with certain parts deleted, showing one embodiment of the ultrasonic-wave painting machine according to the invention
- FIG. 2 is a schematic diagram, partly in perspective view and partly as an electrical circuit diagram, for a description of the principle of the painting machine .of the invention

- An ultrasonic-wave vibrating element tor transducer 7, which is fixed'to a vibrating plate 5, is disposed within this front chamber 3.
- An insulating transformer 11 is housed within the rear chamber 4 of the interrupting device15, by a suitable method, for example, by a method wherein, as shown in FIG. 2, an eccentric cam EC is rotated by a variable-speed motor M causes a switch SW to open and close periodically, thereby causing the suppressor grid G of the oscillating tube 14 to be subjected periodically to a negative.
- the rotational period of the eccentric cam maybe varied or the proportion between the exciting time of the vibrating plate during one period and the time when the said excitation does not take place maybe varied.
- the paint which is, poured out always forms a uniform filmover a Wide area of the vibrating plate 5, and such defective action as atomization only in the vicinity oftheflow outlet or irregularities in the particle sizedue todiiferences in positions of atomization does not occur.
- the ultrasonic-wave generator 8 of the instant embodiment further includes a sweep device 16 which varies the oscillation frequency by a suitable method, for example, by rotating a variable condenser-,VC by means of a variable-speed motor M as indicated in FIG. 2.
- a sweep device 16 tocause the ultrasonic-wave frequency to vary, with a suitable period, within a range wherein the In the operation of the painting machine ofthe above constructional arrangement, when.
- the ultrasonic-wave" vibrating element 7 is excited by the oscillationoutput (at a frequency of approximately kilocycles persecond in the case of the embodiment shown-) 'of the ultrasonic-wave generator 8, the ultrasonic-wave energy propagated by the excitation of the element 7 and deflection of the vibrating plate 5 due to the density of the ultrasonicwave energy concentration in the said vibrating plate 5 cause atomization of the paint supplied from the paint tank 9 and force the paint. particles to be projected onto the article 10.
- the insulating transformer 11 functions to insulate the ultrasonic-wave generator 8 and the vibrating members. 7
- the device for atomizing the paint will now be described in greater detail in conjunction with FIG. 2.
- a thin metal plate 13 is interposed betweenthe vibra ting plate 5 and the vibrating element or transducer 7.
- This thin metal plate.13 has;anarea which is somewhat greater thanthe area of the 'vibrating surface ofthe vi: brating'element 7 and; a thickness which is slightly greater than that of the vibrating plate 5 (in this embodiment, the
- thisthin metal plate 13 has a relatively/high thermal capacity and be a thin plate which will not. cause great variation in the resonance frequency (approximately 40 kilocycles ⁇ per second) of .the vibrating element 7 when only thismetal 'plate is bonded to the. vibrating element.
- Such a thin metal plate 13 functions'to prevent separation of the vi brating element 7 and thevibrating plate 5 and,1at the same time, facilitates the acoustic matching of these. two parts.
- FIG.. 2. This ultrasonic wave ,generator includes, in a'ddition to a high-frequency.'o'scillat ing tube 14,'an,oscillation interrupting device 15 forcaus 'ing the supplied paint to assume the form of a uniform fil on the entire surface of thevibrating plate 5.;
- This of an ultrasonic-wave generator euitable l 'forexciting the vibrating element 7 is represented by the ftration of ultrasonic-wave energy becoming static as in the case of operation with constant frequency.

- a direct-current voltage approximately 35 kilovolts
- the distribution of lines'of electric force will'become dense at the peripheral parts of the vibrating plate if thevibrating plate is a flat plate, and its emission positions, being readily affected by outside influences, will become astatic.
