Abstract: PROBLEM TO BE SOLVED: To actualize an adequate capacity design of various mechanisms used for the post treatment of coating, for example, a mist removing filter for removing coating material mist. SOLUTION: A coating material weight calculation processing is carried out, and a dry coating material deposited quantity is calculated and stored by multiplying a work surface area and a film thickness distribution value together first (S120, S130) and further multiplying the obtained dry coating material deposited quantity and dry coating material specific gravity together to calculate and store coating material dry deposited quantity (S140, S150). Whereas, a discharge coating material dry weight which is a dry weight of the coating material discharged from a coater is calculated and stored by multiplying a discharged coating material weight and the NV of the coating material together (S160, S170). The non-deposited coating material dry weight is calculated and stored by subtracting the sticking coating material dry weight from the discharge coating material dry weight. The capacity design of the various mechanisms is carried out using the non-deposited coating material dry weight. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PURPOSE: To prevent the lowering of painting quality and to rapidly perform a color changeover, in a powder painting booth having a painting chamber to which a painting machine spraying powder paint and possible to change over a color is arranged, by providing both side walls of the painting chamber in a manner reversible so that the inside becomes the outside. CONSTITUTION: When the color of the powder paint applied to an article W to be painted, for example, is changed over from white to red within a painting chamber 11, respective painting machines 18, 19, 19 are subjected to color changeover operation and the respective side wall forming elements 13-1 forming both side walls 12L, 12R of the painting chamber 11 are rotated by 180 deg. so that the inner surfaces 14 to which white powder paint is bonded by painting executed up to now of both side walls 12L, 12R become outside and the cleaned outer surfaces to which no powder paint is bonded of the side walls of both side walls become inside. Therefore, after the color changeover operation of the painting machines 18, 19, 19 is completed, the article W to be painted can be immediately painted with red powder paint. The powder paint of the surfaces 14 made outside of the side wall forming elements 13-1 is removed using a wall cleaning means 31 to provide for a next color changeover.

Abstract: PROBLEM TO BE SOLVED: To actualize an adequate capacity design of various mechanisms used for a post treatment after drying, for example, the capacity design of a deodorization apparatus for removing a volatile organic compound (VOC). SOLUTION: A dry coating material deposited quantity which is a volume of a dry coating material deposited on a work is determined based on a film thickness distribution value and a work surface which are obtained as a result of a film thickness simulation (S300, S330). The dry coating material deposited quantity is multiplied by a coating material dry specific gravity to obtain a deposited coating material dry weight (S340, S350) which is then divided by the NV (nonvolatile content) of a coating material to obtain a deposited coating weight containing a solvent portion (S360, S370). The VOC weight is determined as the deposited coating material solvent weight by subtracting the deposited coating dry weight from the deposited coating material weight (S380, S390). The capacity design of the various mechanisms is carried out using the deposited coating material solvent weight. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide work electrifying type electrostatic coating equipment in which even when a worker's entrance in an automatically coating zone can not be detected, danger for the worker is surely avoided at the time when the worker approaches a work impressed with high voltage. SOLUTION: Approach limit distance against danger in the case of approaching a work W nearer than the limit is previously set. When a worker having penetrated an automatically coating zone Z approaches the work W, distance to the worker is measured by distance measuring sensors S placed on a traveling base 4 and compared with the approach limit distance. When the measured distance is smaller than the approach limit distance, an abnormal detection signal is outputted. Therefore, when the abnormal detection signal is outputted, for example, supply of high voltage impressed to the work W is immediately sopped and also the traveling base 4 and a coating machine 5 are stopped. Thereby, danger for the worker having approached the work W is avoided. Furthermore, generation of the abnormal state is informed also to other worker by generating alarm.

Abstract: PROBLEM TO BE SOLVED: To obtain a coating pattern relatively easily for simulation in consideration of air current and improve the precision of the coating thickness simulation. SOLUTION: To obtain a dynamic coating pattern based on a static coating pattern in consideration of the effect of air current, assuming that the coating pattern alteration owing to air current is linear and that even if the coating pattern is altered, the quantity of a coating material to be deposited on a work is constant, the alteration of the coating pattern owing prescribed air current application is measured and the alteration of the coating pattern owing to arbitrary air current is assumed to be linearly proportional to the coating pattern alteration by the prescribed air current application and in this case the coating thickness simulation is carried out with a computer system while paying an attention that the entire coating pattern is shifted parallel and the pattern width of the coating pattern is widened in the x-axis direction by the prescribed current application and on the other hand the pattern width of the coating pattern is narrowed in the y-axis direction.
