Tire manufacturing method and manufacturing system

A system for manufacturing a tire, the system comprising:

• a plurality of work stations formed in a forming step;
• a forming drum body configured to sequentially move to the work stations;
• a robot arm installed in each of the work stations;
• and
• a vulcanization device and
• having a configuration in which a green tire is formed by performing a forming work of bonding a tire component to the forming drum body by using the robot arm installed in each of the work stations and in which the green tire is vulcanized by the vulcanization device;
• the system further comprising:
• one or a plurality of robot arms being installed in each of the work stations;
• a placement device installed between the work stations adjacent to each other;
• and
• a control device configured to control each of the robot arms,
• all placement devices included in the system, including the placement device, being fixed to a predetermined installation position,
• a plurality of the forming drum bodies being allowed to be temporarily placed between the work stations adjacent to each other, and at least three of the work stations adjacent to each other being provided in the forming step,
• in accordance with a specification of the green tire to be formed, a plurality of the work stations necessary for the forming work being selected from all the work stations by the control device, and a movement path of the forming drum body in the forming step being determined by the control device, and
• the robot arm disposed at a position corresponding to the movement path determined being controlled by the control device, the forming drum body being placed on the placement device disposed at a position corresponding to the movement path to deliver the forming drum body, thereby the forming drum body being moved along the movement path, and the forming work being performed in each of the selected work stations.
