Robot system, conveying device, and wiring method

A conveying device comprising:

• a turning part configured to rotate about a center axis;
• a guide having a hollow in the guide extending along the center axis, the turning part is rotatably supported on an outer peripheral surface of the guide such that the turning part is rotatable about the center axis;
• a workpiece holder configured to hold a workpiece and provided at the turning part to move together with the turning part along a circular orbit around the center axis passing through a working region;
• a first device provided at the turning part;
• a linear object passing through the hollow in the guide and connecting the first device and a second device provided around the guide;
• and
• a cover which is provided on the turning part, the cover having an opening through which the guide extends, wherein
• a gap is provided between the opening of the cover and the outer peripheral surface of the guide, and
• the linear object passing through the gap and being connected to the first device.

A robot system comprising:

• a robot configured to perform work on a workpiece positioned in a working region;
• and
• a conveying device configured to convey the workpiece to the working region and comprising:
• a turning part configured to rotate about a center axis;
• a guide supporting the turning part rotatably about the center axis and having a hollow in the guide extending along the center axis;
• a workpiece holder configured to hold the workpiece and provided at the turning part to move together with the turning part along a circular orbit around the center axis passing the working region;
• a first device provided at the turning part;
• and
• a linear object passing through the hollow in the guide and connecting the first device and a second device provided around the guide, wherein
• a basal part of the robot is fixed to the guide such that the basal part is in a fixed relationship with the guide,
• the guide is configured to be fixed to a floor surface such that the basal part of the robot and the guide are in a fixed relationship with the floor surface,
• the conveying device includes a cover which is provided on the turning part, the cover having an opening through which the guide extends,
• a gap is provided between the opening of the cover and the outer peripheral surface of the guide, and
• the linear object passing through the gap and being connected to the first device.
