Claim:
1. A peeling system for separating a superimposed substrate including a first substrate bonded to a second substrate into the first substrate and the second substrate, the peeling system comprising: a peeling device configured to separate the superimposed substrate into the first substrate and the second substrate; a plurality of first cleaning devices each being configured to clean a bonded surface of the first substrate which was bonded to the second substrate; an inversion device configured to invert front and rear surfaces of the first substrate; a plurality of second cleaning devices each being configured to clean a non-bonded surface of the first substrate; a first conveyance device configured to take out the first substrate from the peeling device and convey the first substrate into one or more of the plurality of first cleaning devices by rotation around a vertical axis and extension and retraction in a horizontal direction; a second conveyance device configured to take out the first substrate from the one or more of the plurality of first cleaning devices and convey the first substrate into the inversion device by the rotation and the extension and retraction; and a third conveyance device configured to take out the first substrate from the inversion device and convey the first substrate into one or more of the plurality of second cleaning devices by the rotation and the extension and retraction, wherein delivery positions of the first substrate in the plurality of first cleaning devices are arranged in a region where an operation range of the first conveyance device and an operation range of the second conveyance device overlap each other, the plurality of first cleaning devices is further configured to be disposed separately in a first place and a second place different from the first place, the first conveyance device is further configured to be disposed such that a non-rotation region thereof is directed toward a positive second direction which is perpendicular to a first direction in a plan view, the first direction being an arrangement direction of the peeling device, the first conveyance device and the first place, the second conveyance device is further configured to be disposed such that a non-rotation region is directed toward the plurality of second cleaning devices, and the third conveyance device is further configured to be disposed such that a non-rotation region thereof is directed toward a negative second direction.
