- a film thickness distribution value is obtained.
- a film thickness distribution value as a result of the film thickness simulation is obtained.
- the input is made via the input mechanism 54 of the weight calculation device 1. Note that the film thickness distribution value is obtained as a coating film thickness value after the paint is dried.
- a work area is acquired. This process is to acquire the painting area of the work, and in this embodiment, it is assumed that the result is input via the input mechanism 54 of the weight calculation device 1 as a result of the film thickness simulation.
- the work area may be obtained from drawing data such as CAD data.
- the work area is multiplied by the film thickness distribution value. Since the film thickness distribution value is a coating film thickness value in each part of the work 13, an integral process is performed here to obtain a dried volume value of the paint adhered to the work 13. Then, in the next S330, the dry paint adhesion amount obtained in S320 is stored.

Then, the adhesive paint dry weight is subtracted from the discharged paint dry weight, and the non-adhesive paint dry weight is calculated and stored (S180, S190).
- the film thickness simulation is repeatedly executed while changing the input conditions, and the paint simulation is performed using the simulation result when the coating efficiency, which is the adhesion efficiency of the paint to the work 13, becomes relatively large.
- Perform weight calculation processing Entering film thickness simulation Since the coating efficiency, that is, the film thickness distribution value differs depending on the force condition, the non-adhesion amount of the coating material becomes smaller by using the simulation result when the coating efficiency becomes relatively large. As a result, it is only necessary to design the capabilities of various mechanisms used for post-coating treatment relatively small, which is economically advantageous.

Further, the above-described paint weight calculation processing corresponds to “non-adhered paint calculation processing”.
- the dry paint adhesion amount which is the volume value of the dry paint adhering to the work 13, is determined based on the film thickness distribution value and the work area obtained as a result of the film thickness simulation (FIG. S300 in 4—S330). Then, the applied paint dry weight is multiplied by the paint dry specific gravity to obtain the applied paint dry weight (S340, S350), and this is divided by the paint NV to obtain the applied paint weight including the solvent component (S360, S370). The VOC weight as the weight of the paint solvent is calculated by subtracting the dry weight of the paint from the weight of the paint (S380, S390).
- VOC weight By using this VOC weight, appropriate capacity design of various mechanisms used for post-drying treatment is realized.

- a weight calculation process and a solvent weight calculation process are performed.
- the coating efficiency that is, the film thickness distribution value
- the coating efficiency differs, so if the simulation result when the coating efficiency is relatively large is used, the amount of paint adhesion increases. .
- a higher coating efficiency is economically advantageous, but also increases the solvent content (VOC weight) in the post-drying treatment. Therefore, according to the present embodiment, it is possible to design the mechanisms of the various mechanisms used for the post-drying process to have sufficient capabilities.
