Abstract:
1. A carrying system for carrying a workpiece between a processing zone where the workpiece is processed by a processing machine and a loading zone substantially opposite the processing zone with respect to a pedestal on which the processing machine is installed, comprising: a first carrying machine configured to carry the workpiece along a substantially arc shaped first carrying route extending between the processing zone and the loading zone, the first carrying route having a middle part protruding away from the pedestal; and a second carrying machine configured to carry the workpiece along a substantially arc shaped second carrying route extending between the processing zone and the loading zone, the second carrying route having a middle part protruding away from the pedestal, the second carrying route being positioned opposite the first carrying route with respect to the pedestal; wherein each of the first carrying machine and the second carrying machine includes comprises a base, a first link, a second link, a first joint joining the first link to the base so as to be turnable relative to the base, a second joint joining the first link and the second link together so as to be turnable relative to each other, and a holding unit mounted on the second link, the holding unit being configured to support the workpiece and to be moved along the first carrying route and/or the second carrying route, the first link having a length longer than a length of the second link, wherein each of the first carrying machine and the second carrying machine further comprises an interlocking mechanism configured to turn the second link relative to the first link in coordination with a turning of the first link relative to the base so that the holding unit is moved along the first carrying route and/or the second carrying route when the first link is turned relative to the base, wherein the base of the first carrying machine is fixed to a side wall of the pedestal facing a transverse direction Y wherein the first link and the second link are configured to overlap each other when the holding unit is near the pedestal, wherein each of the first carrying machine and the second carrying machine further comprises a transmission mode selecting mechanism configured to select:
