ABSTRACT:
A work handling apparatus includes a pair of traveling guides (20, 20′) provided so as to extend in a front-and-rear direction X at right and left sides, and a pair of direct-acting arms (30, 30′) provided so as to travel independently on the pair of traveling guides. The direct-acting arms are extendable from contracted positions, at which the arms oppose each other and avoid mutual interference in a right-and-left direction Y, to extended positions at which the arms overlap with each other. An operation spot (41) is arranged in an operation area (40) sandwiched between the pair of traveling guides for performing a predetermined operation to a work. Also, work tools (60, 60′) are attached to the pair of direct-acting arms (30, 30′), respectively, for transferring the work between a work storage area (50) and the operation spot (41) or performing an operation after transfer.
