Laminate molding system, method for controlling laminate molding system, and method for manufacturing laminate molded article

A laminate molding system in which at least three or more press devices are continuously provided and a laminate molded article is sequentially pressure-molded, the laminate molding system comprising:

• a first press device having a pressure reducible chamber and a pressurizing surface formed of an elastic body sheet, the laminate molded article being pressurized by a first driving force of a first servomotor;
• a second press device having a pressurizing surface formed of a metal press plate or a pressurizing surface formed of an elastic body sheet, the laminate molded article being pressurized by a second driving force of a second servomotor;
• a third press device having a pressurizing surface formed of a metal press plate, the laminate molded article being pressurized by a third driving force of a third servomotor, which are continuously provided;
• and
• a control device for controlling operation of the laminate molding system,
• wherein the control device is configured to measure, using a second position sensor provided in the second press device, a distance between board surfaces of an upper board of the second press device and a lower board of the second press device to obtain a board distance value after pressurization in the second press device, and further configured to perform position control of the third press device based on the board distance value,
• wherein the board distance value provided in the second press device is stored as a reference position A in a storage device of the control device, and position control of the third press device is performed based on a position control value B,
• wherein the position control value B is generated in the control device based on the reference position A.
