Abstract: A two-armed transfer robot is provided which includes an upper arm mechanism and a lower arm mechanism which is substantially identical to the upper arm mechanism. Each arm mechanism is provided with a handling member for carrying a workpiece to be processed. Each arm mechanism is also provided with a pantograph assembly consisting of a base arm, an outer link, a pair of intermediate links and an inner link. The handling member of each arm mechanism is arranged to be spaced from a central driving shaft when the handling member is retreated closer to the shaft. The base arm of the pantograph assembly is inclined away from the handling member when the handling member is retreated closer to the shaft. At the same time, the intermediate links are also inclined away from the handling member.

Abstract: A two-armed transfer robot is provided which includes a first double-pantograph mechanism and a second double-pantograph mechanism which is substantially similar in arrangement to the first double-pantograph mechanism. Each double-pantograph mechanism includes a first pantograph assembly and a second pantograph assembly. The first pantograph assembly is provided with an inner link, a pair of first intermediate links and an outer link. The second pantograph assembly is provided with the outer link in common with the first pantograph assembly, a pair of second intermediate links and a hand-supporting link. The transfer robot also includes a stationary base member, first to fourth shafts coaxially supported by the base member for rotational movement about a vertical axis, first to fourth driving devices for actuating the first to the fourth shafts, respectively. The driving devices are fixed to the base member.

Abstract: A two-armed transfer robot includes a first arm mechanism and a second arm mechanism. Each arm mechanism has a handling member for carrying a workpiece. The robot further includes a stationary base member and four shafts rotatable about a common vertical axis. Driving devices for the respective shafts are attached to the base frame. The first and second arm mechanisms are actuated upon rotation of the shafts driven by the driving devices. When the shafts are rotated in a same direction, the handling members of the arm mechanisms are caused to pivot about the common vertical axis. When the shafts are rotated in opposite directions, the handling members are caused to linearly move toward or away from the axis. The two arm mechanisms are vertically spaced from each other, so that they do not interfere with each other.
