Robot for handling
First Claim
1. A handling robot in which an arm is fastened to an outside of each of a plurality of ring bosses that are arranged coaxially and turnably, deviated in position in a vertical direction, each of such arms is connected via a link to a carrier table so that turning the ring bosses in mutually opposite directions may cause the carrier table to reciprocate in a perpendicular direction to a turning axis and turning them in a same direction may cause the carrier table to turn, characterized in that it comprises:
- a plurality of motor units corresponding to the ring bosses and arranged coaxially with each other and at positions that are lower than a position where the carrier table may operate and that are deviated in a vertical direction;
a connecting member shaped in the form of a cup in cross section and fastened to an output member of each of the motor units, such connecting members being connected to the ring bosses, respectively.

Abstract
A handling robot prevents a positioning in a motor unit power transmission system from becoming inaccurate and can eliminate occurrence of vibrations due to a twisting deformation and so forth in the system. The handling robot has an arm fastened to an outside of each of a plurality of ring bosses that are arranged coaxially and turnably. Each of such arms is connected via a link to a carrier table so that turning the ring bosses in mutally opposite directions may cause the carrier table to reciprocate in a perpendicular direction to a turning axis; and turning them in a same direction may cause the carrier table to turn. A plurality of motor units corresponding to the ring bosses are arranged coaxially with each other and at positions that are insides of the ring bosses and lower than a position where the carrier table may operate. A connecting member is further arranged and is shaped in the form of a cup in cross section and fastened to the output member of each of the motor units, such connecting members being connected to the ring bosses, respectively.

5. A handling robot, characterized in that it comprises a plurality of motor units of direct drive type which are arranged coaxially with each other and disposed at vertically deviated positions, said motor units having their respective motor rotors, at least one of said motor rotors being substantially coincident in position with a corresponding arm of the robot in a vertical direction, each of said motor units having an output member to which the arms of the robot are fastened at at least two sites thereon, each of such arms being connected via a link to a carrier table, said carrier table being adapted both to reciprocate in a perpendicular direction to an axis of said motor units, and to turn.
