If necessary, the paint adjusting device drive unit 4b is driven via the paint adjusting device drive system joints 4c and 4d to cause the paint adjusting device (agitator or the like) 4a to function. The paint is not applied directly to the paint can, not to mention the joints and piping on the equipment side, and the paint circulation / paint adjustment unit is basically loaded on the paint circulation / paint adjustment unit frame 8 to the paint can 5. Is the buoyancy equivalent to the paint immersion portion of the paint feed pipe (paint can side) 2a, paint return pipe (paint can side) 3a, and paint adjusting device (paint can side) 4a (agitator, etc.) immersed in the paint. . If the weight of the paint circulation / paint adjusting unit mounting base 6 and the empty weight of the paint can 5 are subtracted from the indicated value of the weighing machine 9, "net paint weight + buoyancy equivalent value of paint dipping portion" is obtained. Use this value directly for those that require less severe accuracy such as remaining amount management, or
Alternatively, a known paint specific gravity is used to calculate the paint volume for use. Furthermore, when it is required to accurately grasp the amount of paint, the known paint specific gravity and paint feed pipe (paint can side) 2a,
Considering the shapes of the paint return pipe (paint can side) 3a and the paint adjusting device (paint can side) 4a (agitator, etc.), correct the paint immersion part buoyancy equivalent value and calculate and use the net paint weight or paint volume. .
