METHOD AND APPARATUS FOR AUTOMATIC SPRAYING

摘要

PURPOSE:To make a spraying state on a wall surface uniform by increasing the transferring velocity of a spray in a double spraying area wherein the transferring direction of the spray is changed and specifying it in the other area. CONSTITUTION:In an automatic spraying on a wall surface of a building and a tank or the like, while descending a gondola 13 in a specified velocity, a carriage 23 is reciprocally transferred in the horizontal direction and the spraying is performed for a wall surface 15 through a spray 14. In this case, the carriage 23 is relatively transferred in the high velocity in an area wherein the transferring direction of the carriage 23 is reversed. It is transferred in the specified velocity in the other area. In such a way, the spray state for the wall surface of the thickness of the coated film can be made uniform and also the operation is efficiently performed.
