Patent ID: 8590481

Claim:
A dipping apparatus for dipping a workpiece into a treatment bath to treat a surface thereof comprising: a horizontal spindle crossing above the treatment bath; a rotation base rotatably supported about said horizontal spindle; a driving mechanism configured to rotate said rotation base in forward and reverse directions between a horizontal waiting posture above the treatment bath and rotated forwardly and downwardly to an upside down flipped posture from said horizontal waiting posture; a traveling body guiding mechanism provided on said rotation base so as to travelably support and guide a conveying traveling body along a back and forth direction, orthogonal to said horizontal spindle; a ground traveling path from which said conveying traveling body is configured to be transferred onto said traveling body guiding mechanism of said rotation base in said horizontal waiting posture, said ground traveling path serving as both an approach path and a retreat path of said conveying traveling body with respect to said rotation base and connected with said traveling body guiding mechanism only at a rear end of said rotation base in said horizontal waiting posture; a positioning and fixing device to position said conveying traveling body after being transferred from said rear end of said rotation base onto said rotation base via said traveling body guiding mechanism at a fixed position and coupling said conveying traveling body to said rotation base; a feeding mechanism to feed said conveying traveling body to said fixed position on said rotation base positioned by said positioning and fixing device; an operation mechanism to switch said positioning and fixing device between a fixation released state and a fixation active state; wherein said rotation base is supported at a position nearer to a front end thereof than a central position in the back and forth direction thereof by said horizontal spindle, and wherein a support mechanism receives said rear end of said rotation base in said horizontal waiting posture; and wherein said rotation base is composed of a pair of left and right front-back direction frame materials, said traveling body guiding mechanism on said rotation base is composed of a pair of left and right guide rails which are laid on said front-back direction frame materials constituting said rotation base and support wheels of said conveying traveling body, and said support mechanism is composed of a pair of left and right positioning guides to which rear ends of said pair of left and right front-back direction frame materials are fitted and wherein receivers receive said rear ends of said front-back direction frame materials.
