Abstract:
1. A vertical heat treatment system comprising: a lifting mechanism which is vertically moved for carrying a holder, in which an object to be treated is held, in and out of a heat treatment furnace; a holder mounting portion for mounting thereon the holder to transfer the object; a holder transfer mechanism for transferring the holder between the lifting mechanism and the holder mounting portion; a treating-object transfer mechanism for transferring the object to the holder which is supported on the holder transferring portion, the treating-object transfer mechanism having a motion space region which overlaps with a motion space region of the holder transfer mechanism; and a housing having a side face portion proximate to said treating object transfer mechanism wherein said treating-object transfer mechanism comprises a swivel arm supported so as to be rotatable about a vertically extending shaft, and a transfer head having a rotation center shaft provided for rotation about the tip portion of the swivel arm so as to be rotatable on a horizontal plane, and further comprises driving means having a sheltering function, the driving means rotating the transfer head of the treating-object transfer mechanism on its central axis on the horizontal plane along the outer peripheral edge of the lifting mechanism, which is positioned at a lower position, to cause the transfer head to take shelter on a side face portion of a housing.
