SPRAYING APPARATUS AND SPRAYING EXECUTION METHOD

摘要

PURPOSE:To prevent a hose for supplying a spraying material to a nozzle member from being entwined with a motion joint part and being twisted in a spraying apparatus formed by providing a spraying nozzle member on the forward end of a manipulator which comprises plural motion joint parts and is installed on a truck. CONSTITUTION:In a spraying apparatus constructed so that a manipulator comprising plural motion joint parts (rectilinear motion joint and rotary motion joint part) is installed on a truck 1, a spraying nozzle member 21 is provided on the final side rotary motion joint part and a spraying material is supplied to the spraying nozzle member 21 by a hose, a pipe line is disposed in the interior of a rotary motion joint part having the possibility that the hose is entwined and twisted. Hollow pivots 14, 12 of the rotary motion joint part are connected to each other by a joint R2, and the supply pope 22b is connected to the hollow pivot 12 by a rotary joint R3. Thus, entwinement and twisting of the hose can be avoided.
