Abstract: PROBLEM TO BE SOLVED: To determine the thickness distribution of the coating layer formed by an electrostatic coating material spraying apparatus. SOLUTION: A phenomenological and mathematical model of a semi-static three-dimensional spraying pattern is set and used, and specified parameters as fixed input parameters are directly inputted in the phenomenological model. Practical physical input parameters whose effects on the spraying results are not known precisely are supplied to an artificial neural network in which simulation is previously carried out using practical input data. The artificial neural network carries out conversion of the added input parameters into model input parameters to be supplied to the phenomenological model and the spraying patterns formed by the phenomenological model are accumulated in a further functional unit as functions of the movement data of a spraying apparatus 2 included in the input parameters for forming the entire coating layer and the output of the thickness distribution of the coating layer is obtained.

Abstract: PROBLEM TO BE SOLVED: To cope with the precise distribution of coating material thickness by fixing a spray parameter to be set from a desired spray pattern to be attained by utilizing an artificial neural net work learning by using practically measured data. SOLUTION: A coating film is formed by the movement of a spray device in the horizontal or vertical direction and the distribution of the coating film thickness is measured. The profile curve of the distribution of the coating film thickness is shown is the form of 200 individually measured values and a variable to be inputted to the artificial neural net work is expressed by using the measured value. As the input parameter to the artificial neural net work, amplitude is used together with the Fourier analysis of the profile of the coating material thickness distribution, and the spray parameter is fixed from the desired spray pattern to be attained as the output parameter such as the quantity of a coating material, the directing-air quantity and high voltage.

Abstract: PROBLEM TO BE SOLVED: To provide a powder spraying device which carries out electric charging simultaneously in the inside and the outside and is suitable for electrostatic powder coating. SOLUTION: Both of internal high voltage electrodes 2 and an external high voltage electrode 5 are connected with a high voltage power source through high resistance members 1, 3, 4 to improve adhesion efficiency to be constant without largely depending on the distance between the spraying apparatus and the member in a manufacturing process.

Abstract: PROBLEM TO BE SOLVED: To prolong the service life of an electrically insulated piston valve by making the potential of a control electrode equal to the potential of the liquid in a liquid outlet. SOLUTION: The control electrode 2 is arranged on a prolonged part 11 of a cylinder 5. The metallic prolonged part 11 is formed to conform with the shape of the control electrode 2. Then, the control electrode 2 is electrically connected with the liquid 8a at the outlet 9. In the case that the prolonged part 11 is not made of metal but made of an electrically insulated material e.g. glass, the control electrode 2 is placed to be electrically connected between the liquid 8a and the electrode 2 and is welded. The shape of the electrode has at least about 3mm radius of curvature. Thus, the control electrode 2 is always at the potential of the outlet side liquid 8a and lowers the electric field intensity on the valve.

Abstract: PROBLEM TO BE SOLVED: To change the shape of powder cloud during operation by changing the feed of control air by forming a compressed air flow in the tangential direction on a powder/air flow in a space body and expanding and discharging the formed powder/air flow having spin from a powder spray device. SOLUTION: Fluidized powder 8 is put in a scattering device 1 as a dust/air flow from a nozzle 11. The scattering device 1 is constituted as a space 3, and the space 3 is formed of a pipe 4. In the pipe 4, plural drill holes 5 are made in rows on the periphery of the pipe, and compressed air is introduced into the space 3 from the drill holes 5 as control air 6 in contact with the powder/air flow 16 in the tangential direction. As a result, the helical motion of the powder/air flow 16 toward an outlet 12 is strengthened, and the outlet 12 is constituted so as to expand in a funnel. By this way, the shape of expanded powder cloud 15 is changed during operation by changing the feed of the control air 6.

Abstract: Electrostatically sprayed paint parameters suitable as input values for a paint spraying device are determined via at least one artificial neuronal network where each parameter is available as out output of the network. Initially, a learning phase involves inputting a number of realistic measured values into the network or into several networks to provide a paint thickness distribution and the associated realistic spray parameters. User phase input values are applied to the network or networks and result from an analysis of the paint thickness distribution of a specified spray result.

Abstract: The piston valve has a cylinder (5) containing a linearly displaced piston (1), with electrical isolation of the fluid inlet (12) from the fluid outlet (9), so that the fluid (8) can be held at earth potential at the inlet while the fluid (8.1) at the outlet is at a HV potential. The cylinder has an extension (11) associated with a control electrode (2), held at the same potential as the fluid at the valve outlet. Both the cylinder and the extension can be made of glass or ceramics.

Abstract: Determining the distribution of sprayed paint thickness of paint layers formed according to a set spraying parameter using an electrostatic spraying device requires use of a phenomenological mathematical model of a three-dimensional spray image with input of specific parameters such as the rotational angle of the spray device electrodes together with the latter's rate of movement. In addition, actual physical input parameters such as color volumes, pilot air data and high voltage value are supplied to an artificial neuronal network, although their influence on the result of paint spraying is not precisely known. The spray images from the phenomenological model are integrated to a total paint layer in a further functional unit, independent of the movement data.
