摘要： PROBLEM TO BE SOLVED: To provide an airless spray coating apparatus not only contributing to the improvement of atomization extent but also greatly to securing the evenness of atomization. SOLUTION: A plurality of minute coating material nozzles having an opening diameter of 0.02-0.10 mm are linearly arranged in front of a front wall of a nozzle head 1, and a coating material M is fed to the nozzle head 1 from a coating material supplying device 3 with a low pressure of 1-3 MPa to eject from a plurality of the coating material nozzles. A desired coating material ejecting amount is secured even under the condition of a minute opening diameter of the coating material nozzles 2 and a lowered coating material pressure since a plurality of the coating nozzles 2 are provided. In addition, atomization is enhanced by minifying the opening diameter of each coating material nozzle 2 so as to thinning a liquid thread ejected from the coating material nozzle 2, and the evenness of atomization rises by suppressing turbulent flow in the vicinity of nozzle outlets to the extent of lowering the coating material pressure.

SOLUTION: In the washing process which washes the residual coating in a coating pathway by alternately supplying washing air and washing solution in this order or opposite order to the coating pathway through which the coating is supplied to the rotation spraying head, the supply time for supplying the washing solution to the coating pathway at first (B pattern) is lengthened more than that of the standard (A pattern) or the pressure of the washing air supplied to the coating pathway at first is reduced more (C pattern) than that of the standard when the hardness of the pigment included in the coating to be washed is high. The wear of the center cone is controlled by reducing the amount of the remaining coating at the coating pathway in the case of B pattern, and by reducing the speed of the coating at which the washing air impinges to the center cone in the case of C pattern.

摘要： PROBLEM TO BE SOLVED: To prevent the imperfect coating material pulverization and air inclusion at a rotary atomizing head by providing a hollow part with an air vent route in addition to coating material ejection holes and a self-cleaning route in order to withdraw the coating material, etc., entering this hollow part. SOLUTION: The hollow part 16 of the revolving shaft 3 is provided with the air vent route 17 in addition to the coating material ejection holes 15 of the rotary atomizing head 1 and self-cleaning route 14 for withdrawing part of the air for preventing the infiltration of the coating material and detergent accumulating in the hollow part 16 in communication with the hollow part 16 of a revolving shaft 3. If the atomizing head is formed in such a manner, the pressure rise in the hollow part of the revolving shaft is suppressed and the vigorous ejection of the air from the coating material ejection holes and the self-cleaning route do not arise any more and almost all of the coating material arrives at edges by transferring the inside surface of the rotary atomizing head. Then, the coating material is splashed and pulverized therefrom and, therefore, and imperfect pulverization does not arise any more.
